To provide a knitting information recording medium that can be read without discrimination, and a knitting information reading device that can efficiently read information indicating a knitting pattern and the number of needle selection units using the same scanning member as digital electrical signals. It is in.

The present invention will be explained in detail below using illustrated embodiments applied to a home-use hand knitting machine.

First, the overall outline of a hand knitting machine to which the present invention is applied will be explained with reference to FIG. 1. A knitting machine main body X having a needle bed a reading device A equipped with a scanning member (not shown in FIG. 1) that optically scans recorded information;
In addition to this reading device A, manual operations used to manually operate various mechanisms to be described later are provided on the operation panel 2, and a control box B is equipped with various electrical and electronic circuits to be described later. It is installed behind the needle bed X, and
On the needle bed X, there are left and right needle selection range setting switch activation pieces 31 which are point setting means for locating the edge of the knitting needle group where the needle selection range can be divided arbitrarily, that is, the end of the knitting needle group where needle selection is to be performed.
, 3r are mounted at arbitrary positions, and on the back side of the base plate 4 of the carriage Y that runs on the needle bed In response to electrical signals obtained by scanning the knitting pattern, the rows of knitting needles on the needle bed A pair of knitting needle sorting mechanisms are arranged at a predetermined length apart on the left and right sides.

The reading device A has a scanning member mounted on a carriage Y.
(More specifically, when the carriage Y approaches the switch activation piece 31 or 3r)
By automatically scanning the recorded information horizontally and linearly, a corresponding electrical signal is output, and the subsequent processing of the electrical signal is now performed using an electronic configuration. Further, power is supplied to the electrical components of the pair of left and right knitting needle sorting mechanisms by a cord 6 that is passed through a tension member 5 that applies tension to the knitting yarn, and the carriage Y is connected to the switch activation piece. 31
, 3r, only the knitting needles within the distance between the switch starting pieces 31 and 3r are subjected to the effective sorting action (even those within this range are at a rest position where they are not subjected to any sorting action at all). (excluding things).

First, let's talk about the mechanical configuration of the reading device A.
This will be explained in detail with reference to FIG.

It is installed in the frame 7 further behind the rising wall X1 at the rear end of the needle bed X of the entire reading device A, and first therein is a recording medium transport mechanism, that is, the knitting program card 1 is loaded and transported. To explain the mechanism, endless sprocket belts 81 and 8r, which are feeding members, are mounted on the left and right sides of the frame 7 so as to be able to circulate.

The sprocket belts 81, 8r have sprockets 8' projecting from the outer circumferential surface at a constant interval to fit into the left and right perforations 1 of the knitting program card 1, and the sprocket belts 81, 8r on the left and right , by inserting the card 1 between them and a card guide plate 9 having a U-shaped cross section disposed below the perforation 1' and fitting the perforation 1' to the sprocket 8'. The sprocket belts 81 and 8r can support the card 1 in a U-shaped bent state, and in this supported state, the transfer drive mechanism a installed on the right side of the frame 7
By being circulated by the card 1, the card 1 can be transferred in the direction in which the perforations 1' are arranged.

That is, each sprocket belt 81, 8r is shown in FIGS. 3 and 4 (belts 81, 8r are partially cut away).
As shown in the figure, the hook is turned between the lower dog pulley 101.10r and the small boot 11°11r diagonally above it.
Furthermore, the left and right thick boots') 101, 10r are drive shafts 12, and the left and right small boots') 111, 11r are connected to each other by a rotating shaft 13. It is integrally connected to a ratchet wheel 14 of the transfer drive mechanism a, and as the ratchet wheel 14 rotates, the left and right sprocket belts 81 and 8r are simultaneously rotated.

As shown in FIGS. 2 and 4.5, the transfer 1 drive mechanism a has a forward feeding piece 15 on the front side of the ratchet wheel 14, and a reverse feeding piece 15' on the rear side, and these two feeding pieces 15, 15' are connected to a pair of electromagnets 16, 16', respectively.
The ratchet wheel 14 is connected to the plungers 17 and 17' by pins 18 and 18', and the forward and reverse directions of the ratchet wheel 14 are determined depending on which of the dual chamber magnets 16 and 16' is driven.

In other words, both feed pieces 15 and 15' are always kept in such a way that their pawls 21 and 21' are engaged with the ratchet wheel 14 by the springs 19 and 19' acting individually on them and the spring 20 stretched between them. However, when the corresponding electromagnets 16 and 16' are repeatedly energized and deenergized by inputting a pulse electric signal, and the plunger 17 or 17' moves up and down, Each of them rotates a little while moving up and down along the guide pieces 22, 23 or 22', 23' to repeatedly engage and disengage with the ratchet wheel 14.

Therefore, depending on which of the pair of electromagnets 16 and 16' is driven, the forward and reverse directions of the ratchet wheel 14 are determined. It is decided to send it in the direction.

As mentioned above, the card 1 optically scans horizontally and in a straight line, and if there are any irregularities on the line to be scanned, the accuracy of reading the information recorded on the card 1 may be compromised. In order to prevent this, a card receiving plate 24 is stretched between the left and right sprocket belts 81 and 8r, and furthermore, on the left and right sides of the left and right belts 81°8r, the card receiving plate 24 is placed on the left and right sides of the card 1. Left and right card pressers that lightly press the edges, respectively (piece 251)
It is equipped with ゜25r.

That is, as shown in FIG. 3, the upper surface of the card receiving plate 24 is a flat inclined surface that is high on the rear side and low on the front side.
Each card holding piece 251', 25r has a fulcrum on the axis of the drive shaft 12, as shown in the side view of the right side in FIG. It can be rotated around the center, that is, opened and closed, and is biased toward the rear, that is, in the closing direction, by the spring 26, and as described above, the card 1 connects its left and right perforations 1 to the sprockets of the sprocket belt 8tt8r. 8
' and is pressed by the card holding pieces 251, 25r, the card is transferred along the flat inclined upper surface of the card receiving plate 24 while remaining in close contact therewith.

As described above, the portion of the card 1 along the card receiving plate 24 always forms a flat slope over almost the entire length on the left and right sides, and next, the card 1 is automatically scanned horizontally and in a straight line in this flat sloped portion. In order to achieve this, a traveling drive mechanism for automatically traveling the scanning member will be described.

Two upper and lower guide rods 27 and 28 are horizontally suspended in parallel to each other on the frame 7, and a scanning member is mounted on these so as to be able to slide left and right.

That is, as shown in FIG. 3, the scanning member has left and right through holes 29 provided in its main body, the running body 29, slidably fitted into the upper guide rod 27, and the running body 29
The bobbin 30 integrally provided on the lower side of the lower guide rod 28
It is fitted in a slidable manner.

A coil 31 is wound around the pobbin 30, and a horizontally long permanent magnet 32 is placed slightly below the lower guide rod 28 in parallel thereto.

The entire length of the upper side of the permanent magnet 32 is, for example, an N pole, and the entire length of the lower side is an S pole.The lower guide rod 28 is made of a magnetic material, and when a current is passed through the coil 31, the current is , the permanent magnet 32 crosses the magnetic field that is constantly created, and the traveling body 2 is moved by the magnetic force acting between them.
9. Therefore, the scanning member automatically moves to the left or right along the guide rods 27, 28 depending on the direction of the current flowing through the coil 31.

That is, the coil 31 and the permanent magnet 32 are
This constitutes a type of linear motor with 2 serving as a stator.

At positions corresponding to the left and right ends of the permanent magnet 32, as shown in FIG. 7 (cross section taken along the line ■-■ in FIG. 2), left and right limit switches 331 act to switch the polarity of the current flowing through the coil 31. .33r is placed.

The limit switch 331 on the left is turned on when the scanning member collides with the left row, and the right limit switch 33r is turned on when the scanning member collides with the right row. limit switch 3
It moves left and right between 31 and 33r, and these left and right limit switches serve as the left and right stroke ends, and as will be described later, the scanning member is always located at the left stroke end, which is its original position. , in relation to the reversal of carriage Y, it moves rightward from its original position at a considerable speed to the right stroke end, and as soon as it reaches the right stroke end, it immediately reverses (
The left and right limit switches 331 and 33r respectively check whether the scanning member is at the original position or the inverted position (right stroke). end)
It also functions as a means of detecting whether or not it is present.

As shown in FIG. 3, the upper extension 29' of the scanning member running body 29 extends obliquely upward on the rear side, and then extends obliquely downward, and its leading edge is on the inclined surface of the card receiving plate 24. It faces it at a close position, and at its tip is a so-called light-receiving element that consists of a reading element, that is, a light-emitting element, and a light-receiving element that receives reflected light that is reflected from the surface of the card and converts it into an electrical signal. A photoelectric sensor C is installed inside.

As the scanning member travels, its photoelectric sensor C optically scans a straight line along the card receiving plate 24 of the card 1. Hereinafter, the photoelectric sensor C will be referred to as a scanning sensor. Make it.

Next, card 1 will be explained with reference to FIG. 2. It is translucent, and the perforations 1' on its left and right
On the white surface in between, a knitting pattern recording section 1b, which is a part for recording the knitting pattern, and
The function mark entry field 1f, which is the organizing function information recording area on the right side, that is, the area where the function mark is recorded, is set to a color that is the same as the emission color of the light emitting element of the scanning sensor C and that the light receiving element does not discriminate (for example, the light emitting element is red). It is created by displaying the grid division lines (red when using light emitting diodes) in advance using an appropriate display method such as printing, and is read by the scanning sensor C on the left side of the knitting pattern entry field 1p. A large number of feed control marks 34, which can control the feed amount of the card 1, are displayed, for example, slightly thick horizontal black lines at regular intervals in the direction in which the perforations 1' are arranged. By doing so, you can record it in advance.

The spaces between the entry fields 1p and 1f and between the entry field 1p and the feed control mark 34 are blank.

In the above-mentioned knitting pattern entry field 1p, the vertical lines of the grid dividing lines that constitute it are the dividing lines between the stitches, and the horizontal lines are the dividing lines between the knitting rows, and below the outside of the field, The numbers representing the stitches are displayed in the same color as the grid dividing lines.

More specifically, in the knitting pattern entry field 1p, one minimum section, that is, a witness grid corresponds to one stitch,
The horizontal arrangement, or row, corresponds to one knitting needle, and the vertical arrangement, or row, corresponds to a knitting row (wale), and n horizontal rows of stitches are considered as one group. When knitting a so-called unit pattern, the vertical line at the left edge and the vertical line 0 vertical lines to the right of it are regarded as the boundary line, and a picture (knitting pattern) corresponding to the unit pattern to be knitted is drawn between them. is extracted solidly in black using an appropriate writing instrument such as a pencil, for example, as shown in the figure.

For example, when knitting a unit pattern of 12 stitches in a horizontal row by selecting 12 knitting needles as a unit of one group, the vertical line at the left edge and the vertical line at the 12th edge are This is to extract pictures within the range.

At this time, as long as the outline of the picture is within the above range, the inside of the picture may be filled in solidly without filling in the witness grid one by one.

This is because the reading is performed by sampling each witness grid, and this will be explained in detail later.

Further, in the function mark entry field 1f, the horizontal line is on the same line as the horizontal line of the knitting pattern entry field 1p, the vertical line is parallel to the vertical line of the knitting pattern entry field 1p, and the function mark entry field is The rows (vertical rows) of the witness grid in 1f are arranged on the same line as those in the turn entry field 1p, and there are the same number of rows (
For example, if the knitting pattern entry field 1p is 3
There are 4 instead of 6.

The function mark entry field 1f is used to mark (for example, fill in black) any witness grid when performing a required function operation.In this example, a total of four witness grid columns (vertical The left column is for programming the forward direction of card 1, and the column to the right is for programming the reverse direction of card 1. The other two columns are for programming required function operations other than card feeding, such as thread exchange and start/end of needle selection operations, respectively.

Further, in this example, the feed control marks 34 displayed in advance on the left edge are individually positioned on the extension line of the horizontal center line of each stage of the witness grid in the knitting pattern entry field 1p. As will be described later, the card 1 is automatically advanced to each stage of the criminal grid.

Furthermore, in addition to the three types of displays mentioned above, the card 1 also has a needle selection unit number setting section that allows you to program the number of needle selection units arbitrarily by recording information that instructs the number of needle selection units. The number setting field 1s is also displayed in advance in the same color below the knitting pattern entry field 1p.

In this setting field 1s, a required number of independent rectangular criminal grids 35 are arranged horizontally at regular intervals.
It is displayed in columns, and each grid is unique for setting a fixed number of needle selection units, and the number of units set is different from each other, and The set number of units increases in a predetermined base number, and a number representing the number of needle selection units is displayed in advance in the same color below each culprit grid 35.

In this example, the number of culprit grids 35 is 6 in total, and the one on the left is the number of needle selection units "6", and the following numbers are 1-12, 18, 24, 30, 36J in hexadecimal. .

Therefore, this needle selection unit number setting column 1s is also scanned by the scanning sensor C of the scanning member, and the number of needle selection units is set in which of the culprit grids 35... The number of needle selection units is determined by information for setting, that is, whether marks are applied.

For example, when knitting a unit pattern using 12 knitting needles, the culprit grid 35 labeled "12" is painted black.

Further, search information, that is, a search mark 36, is displayed on the card 1 in advance in order to enable effective reading of only the setting field 1s in the electrical signal processing process after reading by the scanning sensor C, as will be described later. It is.

This mark 36 is composed of, for example, a horizontally long black band with the same vertical width as the vertical width of the criminal grid 35 in the setting field 1s, and its position on the card 1 is in the direction in which the criminal grid 35 is arranged. On the extension line and the feed control mark 34...
...-, but its width is longer to the right than that of the feed control mark 34... and is between the feed control mark 34... and the knitting pattern entry field 1p. The length includes the width of the blank space.

Then, with the card 1 loaded on the left and right sprocket belts 81 and 8r as described above, when the scanning member is in its original position (right stroke end), the card 1 is placed within the length range of the feed control mark 34. The position of the card 1 is read by a scanning sensor C, and the card 1 is automatically transported according to the feed control mark 34 only when the scanning member is in its original position. When the reversal position (right stroke end) is reached, the grid row on the right side of the function mark entry field 1f can be read, and the range between these two reading positions is the same as the movement of the scanning member. It is meant to be read inside.

Therefore, before starting the knitting operation, the card 1 scans the needle selection unit number setting column 1s using the scanning sensor C of the scanning member, and then repeats the automatic step-by-step feeding with the knitting operation. The knitting pattern entry field 1p and the function mark entry field 1f are scanned step by step by the same scanning sensor C, and such scanning is performed by the forward and backward moving steps of the scanning member as described above. However, as will be described later, only the electrical signals associated with the forward (rightward) stroke of the scanning member are effectively extracted from the electrical signals associated with the scanning of both the reciprocating strokes.

By the way, as mentioned above, in the knitting pattern entry column 1p,
The scanning sensor C, which is a scanning member, scans horizontally and linearly for each stage of the witness grid. The electrical signal related to one-stage scanning is the first
As shown in Figure 8 [■] (an example when card 1 is scanned along the p2-p2 line in the same figure), the aspect of the knitting pattern in the first stage of the witness grid, that is, the knitting pattern 1
The electric signal obtained by scanning is a square wave according to the horizontal scanning mode, and if it is only this, the electrical signal obtained by scanning will not have a one-to-one correspondence with the knitting needle to be selected, and it will not be possible to write the function mark. The function mark entered in column 1f is also read by the scanning sensor C in the same way as the knitting pattern, becomes an electric signal in the same electrical system, and is also displayed in advance.

The search mark 36 is also read in the same way and becomes an electrical signal in the same electrical system, but these three
The electrical signals related to reading the knitting pattern are separated from each other, and the electrical signals related to reading the knitting pattern are converted into digital electrical signals corresponding to the knitting needles in a one-to-one relationship, and the electrical signals related to reading the function marks are also converted to the digital electrical signals related to reading the function marks. The mechanical structure of the sampling mechanism that performs such an operation, that is, a sampling operation, which is separated for each witness grid row (vertical arrangement) in column 1f, will be explained with reference to FIGS. 2 and 3.

The frame 7 is located behind the running body 29 of the scanning member.
The horizontally long plate-shaped linear encoder 37 is connected to the guide rod 27.
．． It is horizontally mounted parallel to 28.

In order to sample only the search mark 36 on the card 1, the linear encoder 37 is installed at a position corresponding to a blank space between the feed control mark 34... and the knitting pattern entry field 1p on the card 1. ,
One search mark sampling slit 38s is bored, and a predetermined number (120 in this example) of knitting pattern sampling is provided on the right side of the slit 38s for sampling the knitting pattern drawn in the knitting pattern entry field 1p. 38p......, in the knitting pattern entry field 1p, from the position corresponding to the witness grid row on the left side, to the right in a straight line at regular intervals, and write it in the entry field 1.
A predetermined number (four in this example) of function mark sampling slits 38f are arranged in a row to a predetermined position exceeding the right edge of p. of,
The holes are drilled in correspondence with each witness grid row in the function mark entry field 1f in a 1:1 relationship.

On the other hand, on the rear side of the scanning member running body 29, there is a photoelectric sensor for optically reading the three types of slits 38 s, 38 p p 38 f, that is, a light emitter that illuminates the front surface of the linear encoder 37. A sampling sensor d consisting of a light receiving element and a light receiving element that receives the reflected light is attached.

As the scanning member s travels, the sampling sensor d scans the slits 38s, 3.8p, . . .

It outputs a pulse, that is, a sampling pulse according to Only the forward stroke of both the forward and backward strokes is shown in Figure 13 [■
] As shown in FIG. The 120 sampling pulses for sampling the function mark and the 4 sampling pulses for sampling the function mark are separated from each other.

By the way, when sampling the knitting pattern, 120 Surin IJ 38p were used for that purpose.
The reason why we were able to obtain 3 sampling pulses was because the number of rows (horizontal arrangement) of the witness grid in the knitting pattern entry field 1p was set to 3.
This is to make it possible to apply the card (FIG. 20) with the number of rows of "120" as described later, in addition to the above-mentioned card 1 having the number of columns "6".

Therefore, for card 1 whose number of columns is "36",
Three slits 38p correspond to each witness grid in the knitting pattern entry field 1p, and the witness grid 1 corresponds to three slits 38p.
Three sampling pulses are changed for each scan, but as will be described later, when organizing by card 1 with the number of columns "36", as shown in Fig. 13 (XV)
As shown in , two of the above three sampling pulses
is removed, and the electrical signal related to the scanning of one witness grid is sampled by the remaining one sampling pulse.

In this way, the electrical signal related to one stage scanning of the knitting pattern entry field 1p is sampled for each witness grid, and
As shown in Figure (xvi), each bit corresponds to each witness grid, and therefore one knitting needle, and is converted into a digital electrical signal that determines whether it is a month or a zero depending on whether each witness grid is marked or not. The digital electrical signals are stored in a predetermined memory sequentially from left to right, as will be described later.

Then, the stored digital electric signal is transferred to the carriage Y.
The needles are sequentially and repeatedly read in accordance with the running timing of the carriage Y, and are supplied to one of the pair of left and right knitting needle selection mechanisms (this configuration will be explained later) that is to be operated effectively. It is now possible to do so.

The reading device A is mechanically configured as described above.

Next, we will discuss the mechanical configuration of the carriage Y side in Sections 3.8 to 3.8.
This will be explained with reference to FIG.

As mentioned above, the main hand knitting machine automatically starts running the scanning member by reversing the left and right running of the carriage Y.
In order to do this, it is necessary to automatically detect the reversal of the carriage Y in left-right travel, and the effective scanning of the knitting pattern by the scanning sensor C of the scanning member is performed only during the working process, and digital electrical signals related to the scanning are transmitted. In contrast to storing data in memory sequentially from left to right,
The actual needle selection operation, which is performed by reading out the digital electric signal stored in the memory, is performed during both the reciprocating strokes of the carriage Y, with the left and right knitting needle selection mechanisms operating alternately according to the traveling direction of the carriage Y. In order to knit a pattern similar to the knitting pattern drawn on card 1, it is necessary to detect the running direction of the carriage Y and use the detected signal to control the storage and reading of digital electrical signals in the memory. Must be.

Therefore, the rear side of the carriage Y is shown in Fig. 8 (the right half of the carriage Y shows the top surface of the plywood with the top cover removed, and the left half shows the back surface) and Fig. 9. It is equipped with a carriage reversal switch mechanism E at the center of the edge, and this will be explained first.

A horizontally rectangular sheath frame 39 is fixed on the base plate 4 of the carriage Y, and a switch actuator 40 is fitted therein so as to be able to slide back and forth within a predetermined length range from side to side.

The switch actuator 40 is made into a single plate-like unit by sandwiching a connecting piece 41 having a T-shaped cross section and a magnet piece 42, which slide on the upper surface of the sheath frame 39, between two front and rear magnetic plates 430, 43□. The two magnetic plates 431, 43□
The lower end of the horizontally elongated hole 4' provided in the base plate 4 and the base plate 4
The lower end surfaces of the magnetic plates 43□, 43□ pass through a horizontally elongated hole 44' provided in the slide pipe 44 fixed to the needle bed
It is designed to be constantly attracted to a carriage guide bar 45 made of a magnetic material and placed horizontally above.

On the other hand, a microswitch e having three switch parts e1 to e3 is fixed on the rear side of the sheath frame 39, and a lever e of the switch e is attached to the rear wall of the sheath frame 39. The hole 43 of the magnetic plate 43□ on the rear side passes through the window hole 39'.
' is involved.

Therefore, the switch actuator 40 is fitted into the sheath frame 39 so as to be able to slide freely within a predetermined range on the left and right, and is attracted to the carriage guide bar 45, thereby allowing the carriage Y to move. When the carriage Y is moved to the left, it is slid to the right sliding limit position with respect to the sheath frame 39 and then moved with it, and when the carriage Y is moved to the right, contrary to the above, it is slid to the left sliding limit position. After being moved, the switch actuator 4 will move with it.
16 (I), the lever e' of the microswitch e is switched to the left or right by the left/right switching operation of 0, and the switch e operates to switch one of them, that is, the switch section e for detecting the carriage traveling direction. Or the first
As shown in FIG. 8 (II), by reversing the running of the carriage Y, a binary electric signal is reversed from rHJ to rLJ or vice versa.

Next, the left and right knitting needle selection mechanisms Fl and Fr, which ultimately perform the front and rear selection of the knitting needles N, will be explained with reference to Figures 3 and 8 and 10.The arrangement of the component parts of both mechanisms is symmetrical. However, they have essentially the same structure.

The electromagnet 46 is installed on the carriage base plate 4, and
The upper and lower magnetic poles each have a single piece integrally molded with magnetic material.
One ends of the pair of magnetic conductors 47 and 48 are joined from above and below, respectively, so that different magnetic poles are excited in both magnetic conductors 47 and 48.

On the other hand, a bat guide 49 made of a non-magnetic material is fixed to the lower surface of the carriage base plate 4.

This bat guide body 49 has a bat passage 49 long from side to side on its lower surface, and in the bat passage 49,
The butt N' of the knitting needle N set at the needle selection receiving position can be received through the side cam 50.

The front and back of this bat passage 49 are almost the same as those of the bat N', and the upper wall surface of the bat passage 49 is such that the outer half 49 □ on the outside as seen from the carriage Y descends inward as shown in FIG. On the tapered surface, the inner half 493 is the butt N.
The horizontal plane is slightly lower than the steady height of ′.

Therefore, in the process of passing through this bat passage 491, the bat N' is pushed toward the leaf spring 5 from the middle of the outer half portion 492.
1 (Fig. 3) and is gradually pushed down, and the inner half 4
93 and passes through the butt passage 491 in a snugly fitted state.

In the bat guide 49 having such a structure, the one magnetic conductive body 47 has the outer end of the horizontal portion below the carriage base plate 4 embedded in the thickness of the bat guide 49 from the front side. , a part thereof faces the inner end of the bat passage 491, and the lower surface of the horizontal part faces the inner end of the bat passage 491.
The inner half 493 of the upper wall surface of 1 and the surface continuing therefrom.

Further, the other magnetic conductor 48 has a notch 481 extending halfway from the upper side in a vertical portion below the carriage base plate 4, and the electromagnet 46 Although the magnetic force acts on the inner vertical portion 483, it hardly acts on the inner vertical portion 483.

The magnetic conductor 48 has its outer vertical portion 482 along the rear wall surface of the bat passage 49□, and the bat passage 49,
The vertical front surface from the outer vertical part 48□ to the inner vertical part 483 faces inward from the inner end (bat outlet) of the bat passage 49, as shown in FIG. The surface is inclined to .

In addition, the width t is slightly shorter than the arrangement pitch of the knitting needles N on the left and right sides of the outer vertical portion 48□ of the magnetic conductor 48, and the batt N' passing through the butt connecting portion 491 is vertically The rear surface is brought into pressure contact with the vertical front surface of the portion 48 □, and the head end is brought into pressure contact with the horizontal lower surface of the other magnetic conductor 47, and the front surface of the inner vertical portion 483 of the magnetic conductor 48 is also pressed against the horizontal lower surface of the other magnetic conductor 47. A rearwardly inclined gap passage 51 (FIG. 8) is formed between the horizontal portion and the rear edge of the horizontal portion.

Therefore, the selection of the knitting needles N having the rose l-N' inserted into the butt passage 491 is performed as follows.

The bat N' that has entered the bat passage 49 is gradually pushed down with its back and forth movement restrained as the carriage Y travels, and its head end is brought into pressure contact with the horizontal lower surface of one of the magnetic conductors 47. The rear surface is brought into pressure contact with the vertical front surface of the other magnetic conductor 48 while passing through the magnetic conductor 48 .

If the electromagnet 46 is in an excited state during this width t, that is, while the carriage Y is traveling for one pitch of knitting needles, the magnetic conductor 47
Different magnetic poles are excited in the outer vertical part 48□ of the magnetic conductor 48, and a kind of magnetic path is formed between them via the rose t-N', and the outer vertical part 48□ of the magnetic conductor 48 is excited. Because the 48□ is tilted backwards, the bat N
' is slightly attracted and biased backward along its outer vertical portion 482, deviates from the horizontal lower surface of the magnetic conductor 47, enters the gap passage 51, and immediately rises to a steady height behind the horizontal portion of the magnetic conductor 47. become.

The butt N' that has entered the gap passage 51 is formed on the carriage base plate 4 by the rising part of the magnetic conductor 47 and the rising part extending from the inner vertical part 483 (portion not subjected to the magnetic action of the electromagnet 46) of the magnetic conductor 48. By disposing a magnet piece 52 between the carriage Y and the carriage Y, the magnet piece 52 is subsequently attracted and biased rearward, and the carriage Y passes through a rearward guide passage formed by a group of cams arranged on the back surface of the carriage Y.

On the other hand, when the electromagnet 46 is in a non-energized state, the bat N' is not attracted to the straight path 482 on the outer wall of the magnetic conductor 48, and after passing through the bat passage 49□ while being pushed down to the horizontal part of the magnetic conductor 47. The beam also travels straight, rises to a steady height beyond the inner edge of the horizontal portion, and then passes through a forward guide path different from that in the case of excitation.

The left and right knitting needle sorting mechanisms Fl and Fr are set to the one that should be effectively operated by switching the electromagnet changeover switch section e2 in the microswitch e of the carriage reversal switch mechanism E according to the traveling direction of the carriage Y. Only the electromagnet 46 (in this example, the one on the front side in the traveling direction of the spearhead Y) is supplied with power for the needle selection operation.

The left and right knitting needle sorting mechanisms Fl and Fr are configured as described above, and the knitting needles N with the butt N' fitted into the butt passage 49 However, even with the inserted knitting needles N, it is the left and right needle selection range setting switch activation pieces 31.3r mentioned above.
If the electromagnet 4 is located outside the range of
6 does not receive any excitation command and remains in a non-excited state, so that it is not subjected to the above-mentioned sorting action by the electromagnet 46. Next, see FIGS. 8 and 9 for such a configuration. Explain.

Left and right switch activation piece 31.3r which is a point setting means
Both have a cam groove 3□ running left and right on their upper surface, and a plurality of protrusions 3□ that fit into the needle groove x2 from the upper side protrude from the front end of the lower surface, and knitting needles N on the front side.
A plurality of butt receiving grooves 33 are formed that can snugly receive the hat N' of the needle groove x2. However, the shapes of the cam grooves 31 are symmetrical to each other. .

In other words, the left switch activation piece 31 is arranged so that the front and rear cam parts 34° 3, which form the front and rear wall of the cam groove 3 On the other hand, the relationship of the right switch activation piece 3r is opposite to that described above.

On the other hand, a switch on the base plate 4 of the carriage Y is engaged with the switch activation pieces 31 and 3r as the carriage Y runs, thereby operating a switch.

That is, a pair of left and right needle selection end detection switch mechanisms Gl detect the points determined by the switch activation pieces 31, 3r.

It is equipped with Gr.

The left and right switch mechanisms Gl and Gr have substantially the same structure, although the mutual arrangement of component parts is symmetrical.

The crank 53 is connected to the carriage base plate 4 by a pivot 54.
A protrusion 55 is provided on the lower surface of the carriage base plate 4 to project downwardly through the window hole 4'' of the carriage base plate 4, and the other end The base plate 4
The crank 53 is connected to the lever of the micro switch 56 mounted on the top, and as the carriage Y travels, the protrusion 55 passes through the cam groove 3□ of the left or right switch activation piece 31s3r. It rotates to switch a microswitch 56.

That is, the left and right switch mechanisms Gl and Gr microswitches 56 and 56 have corresponding protrusions 55.
, 55 are both turned on when they are within the distance between the left and right switch activation pieces 31 and 3r, and turned off when they are outside this distance.

The left and right protrusions 55, 55 are located at the sorting points of the left and right knitting needle sorting mechanisms Fl and Fr, that is, on the rear extension line of the width portion, and the left and right switch mechanisms Gl, Gr is a switch activation piece 3t where the selection points of the left and right knitting needle selection mechanisms Fl and Fr are on the needle bed X, respectively.

When approaching the installation position of 3r, the switch operates and outputs an electrical signal that inverts rHJ to rLJ or vice versa, as shown in Figure 18 CI) (IV), and both of these switch mechanisms The electrical signals Gl and Gr are sent to the effective needle selection range indicating switch section e in the microswitch e of the carriage reversal switch mechanism E.
3, only the one on the side where the effective needle selection operation is performed is taken out.

Therefore, as shown in FIG. 18 [■], the effective needle selection range indicating switch part e3 is turned off after the needle selection end detection switch mechanism Gl or Gr on the side that performs effective needle selection is switched on. In other words, while the needle selection point of the knitting needle selection mechanism Fl or Fr on the front side in the direction of movement of the carriage Y is within the interval between the left and right switch activation pieces 31.3r,
It outputs a signal rHJ indicating the effective needle selection range, and outputs a signal rLJ beyond the above-mentioned interval range, and the above-mentioned IH
j Output In other words, the above-mentioned memory storing the digital electric signals related to the knitting pattern is read out, and only during that time the electromagnet 46 on the side that performs the effective needle selection operation is energized.
It is designed to receive de-energized control.

In this way, reading of the memory is performed only within the effective needle selection range determined by the left and right switch activation pieces 31.3r, but the reading is performed because the traveling speed of the carriage Y is not constant and varies greatly. , must be done in accordance with the timing of carriage Y travel.

Therefore, a photoelectric sensor H1°Hr is attached to the carriage Y at the rear end of the base plate 4 at a position corresponding to the left and right knitting needle sorting mechanisms Fl and Fr. However, the slits x3, which are arranged in a row in a one-to-one relationship with the needle grooves x2, are formed on the rising wall x1 at the rear end of the needle bed X, using a kind of linear encoder. By reading the data as the carriage Y travels, the photoelectric sensors Hl and Hr output a pulse, that is, a timing pulse, that matches the timing of the travel of the carriage Y, as shown in FIG. 18 (1). This timing pulse controls the reading of the aforementioned memory, and hereinafter the photoelectric sensors H1 and Hr will be referred to as timing pulse generators.

In addition, the pulses from the left and right timing pulse generators H1 and Hr are sent to the knitting needle selection mechanism Fl or F on the side that performs effective needle selection operation by the carriage reversal switch mechanism E.
Only those corresponding to r are extracted as valid.

The mechanical configuration of the hand knitting machine is as described above, and next, the electrical and electronic configuration will be explained.

First, the card 1 is scanned and fed,
The outline of the configuration of the input function section that stores the read knitting pattern in the memo IJMEM as a digital electric signal will be explained with reference to FIG.

Of the electric signals related to card scanning by the scanning sensor C, only those related to the rightward stroke of the scanning member from the original position, which is the left stroke end, to the reversed position, which is the right stroke end, are valid by the effective scanning data forming circuit C. It is taken out as a card feeding and scanning instruction circuit C8, a needle selection unit number setting circuit NS, a memory control circuit MC, and a function discrimination circuit FS.

The card feeding and scanning instruction circuit C8 receives an electric signal when the left limit switch 331, which is a scanning member original position detection means, is turned on. Only when the card 1 is in the position, it is determined whether the electric signal from the effective scanning data forming circuit C is "H" or II, 1, that is, whether the display on the card 1 is a mark or no mark, An electric signal corresponding to the determination result is supplied to the card feeding and scanning control circuit SC, and the control circuit SC thereby controls the card feeding drive circuit CD according to the mark/no mark mentioned above for card feeding. Electromagnet 16
Alternatively, the card 16' is driven so that the card 1 is automatically transferred by the distance between the search mark 36, feed control mark 34, etc. displayed thereon.

Further, the instruction circuit C8 is configured to receive an electric signal representing the effective needle selection range from the effective needle selection range instruction switch section e3.
When the needle enters from outside the effective needle selection range divided by the left and right switch activation pieces 31 and 3r, an instruction signal for starting the scanning member to travel is input to the control circuit SC. Furthermore, the control circuit SC is configured to receive an electric signal when the right limit switch 33r, which is the scanning member reversal position detecting means, is turned on, thereby causing the control circuit SC to operate as the scanning member drive circuit. SD is controlled so that the drive circuit SD also supplies sufficient current to the coil 31 of the scanning member to enable the scanning member to travel back and forth in one go.

On the other hand, among the sampling pulses related to the linear encoder reading of the sampling sensor d, only those related to right row scanning are taken out as valid ones by the effective sampling pulse forming circuit and inputted to the pulse separation circuit PS. The pulse for sampling the search mark 36 above, the pulse for sampling the knitting pattern, and the pulse for sampling the function mark are separated from each other, and
Here, the pulses (120 pulses in total) for sampling the above-mentioned knitting pattern are for each witness grid when using card 1 in which the number of rows of the witness grid in the knitting pattern entry field 1p is "36" as described above. Two pulses are thinned out and the remaining pulses are sent to the write address designating circuit WA and the memory control circuit MC, and one pulse for sampling the search marks 36 is used to set the number of needle selection units. In addition to the circuit NS, four pulses for sampling the function mark are input to the function discrimination circuit FS.

The needle selection unit number setting circuit NS samples the electric signal related to the reading of the search mark 36 from the effective scanning data forming circuit C according to the one pulse inputted, and determines the number of needle selection units. The setting circuit NS receives instructions for electrically presetting the mark in the number setting field 1s, that is, the number of needle selection units. If the pulse before thinning is input, the number of needle selection units setting field depends on how many of the pulses the electric signal related to reading the mark in the number of needle selection units setting field 1s is input from the effective scanning data forming circuit C. The number of needle selection units programmed in 1s is stored using a digital electrical signal, that is, the number of needle selection units is electrically preset.

Then, the needle selection unit number setting circuit NS determines whether or not to thin out the pulses for sampling the knitting pattern and how many pulses to thin out in accordance with the stored number of needle selection units. For example, when the number of needle selection units is between "6" and "86", the pulse separation circuit PS is controlled to thin out two needles at a time as described above. The setting circuit NS receives an instruction to electrically preset the number of needle selection units as described above, and controls the card feeding and scanning instruction circuit C8 and the card feeding and scanning control circuit SC,
After the scanning member scans the needle selection unit number setting field 1s once and returns to its original position, move the card 1 to the bottom of the scanning member feed control mark 34. It is designed to automatically move until the mark is read.

The write address designating circuit WA - includes a binary counter that counts the pulses inputted from the pulse separation circuit PS as described above, and writes a parallel binary electrical signal to the memory control circuit MC according to the counting result to designate a write address. It is designed to be input as a signal.

The memory control circuit MC samples the electrical signal related to the scanning of the knitting pattern from the effective scanning data forming circuit C using the pulses from the pulse separation circuit PS as described above, and samples the electrical signal related to the scanning of the knitting pattern from the effective scanning data forming circuit C, and assigns the electrical signal to each knitting needle and each bit corresponding to each other. After converting the digital electrical signal into a digital electrical signal (see FIG. 13 [X■]), the digital electrical signal is sequentially transferred to a certain fixed address of the memory MEM, and moreover, to a certain fixed address of the memory MEM under the addressing control of the write address specifying circuit WA. An electric signal corresponding to the carriage running direction from the running direction detection switch e1 is used to store the left-hand scanning of the carriage Y and the right-hand scanning in separate storage sections, that is, two memories. It is designed to be stored separately in each section.

The function discrimination circuit FS uses the four pulses inputted from the pulse separation circuit PS as described above to
The electric signal related to function mark scanning from the effective scanning data forming circuit C is entered in the function mark entry field 1f.
Samples are taken for each witness grid row, and the sampling of the two columns on the left side of the witness grid row is inputted to the card feeding and scanning control circuit SC, and the card 1 is sent to it in the forward direction or in the reverse direction. In addition, the sampling related to the two columns on the right side is inputted to the function drive circuit FD, which controls necessary function operations such as thread exchange operation.

Further, the card feeding and scanning instruction circuit C8, the control circuit SC, and the memory control circuit MC operate a manual operation means, that is, a clear button CB provided on the operation panel 2 (FIG. 1) of the control box B. This enables manual control, and by operating the button, the card 1 can be moved one step in the direction opposite to the direction of movement before the button was operated, and the data currently stored in the memory MEM can be cleared. This is to facilitate re-knitting in case of incorrect knitting.

Further, the card feeding and scanning control circuit SC is controlled by operating another manual operation means, that is, a stop button SB, which is also provided on the operation panel 2, and the transfer of the card 1 can be stopped by operating the button. It is possible to do so.

Furthermore, when performing a special organization, by operating the special function button W, which is also provided on the operation panel 2, the card feeding and scanning instruction circuit C8 is controlled, and the card feeding and scanning perform special operations. It is now possible to do so.

Next, the specific configurations of the effective scanning data forming circuit C, effective sampling pulse forming circuit D, pulse separating circuit PS, needle selection unit number setting circuit NS, and function discrimination circuit FS will be explained with reference to FIGS. 12 and 13. do.

The R-S flip flop 60 is set by the limit switch 331 on the left side, which is a scanning member original position detection means, and reset by the right limit switch 33r, which is a scanning member reversal position detection means, so that the scanning member is moved from its original position. AND gate 61c only during the forward stroke of traveling to the reverse position.

61d is opened, and only during this time the output signal of the scanning sensor C and the sampling sensor d are
and the output signals of the effective scanning data forming circuit C5, respectively.
AND gate 61c as an output signal of effective sampling pulse forming circuit 'D.

61d (Fig. 13 [■
], [■], [I]).

As shown in FIG. 13(n), the output of the limit switch 331 becomes "H" when the scanning member moves away from the original position at ILj. An R-S flip-flop 62 for separating 36 sampling pulses,
It is set when the scanning member moves away from the original position, and is reset by the fall of the first pulse (pulse for sampling the search mark 36) from the effective sampling pulse forming circuit. .

The output of the flip-flop 62 opens the AND gate 63 which receives the pulse from the effective sampling pulse forming circuit. Pulses excluding the pulses for sampling the search marks 36, pulses for sampling the zigzag pattern, and pulses for sampling the function marks are output.

On the other hand, the Q output of the flip-flop 62 is added to the AND 64, which is the Q output of the flip-flop 62.
When the output of the effective scanning data forming circuit C and the output of the effective sampling pulse forming circuit are both rHJ, that is, the scanning sensor C detects the search mark 36 on the card 1 and the needle selection unit number setting field 1s. When performing cross-scanning (scanning along the X-ray in Fig. 13 pt 9, the figure [v] is the output waveform of the effective scanning data forming circuit C at that time), the sampling sensor d is used for sampling the search mark of the linear encoder 37. slit 3
When 8s is detected, one pulse is output as shown in [VI].

Therefore, this pulse output from AND64 is
This indicates that the search mark 36 has been detected.

The R-S flip-flop 65 stores the fact that the search mark 36 has been detected by the output of the AND 64 (actually, the output is inverted by the knot 54').
is now set.

This flip-flop 65 is reset by the output of AND66.

The AND 66 is inputted with the Q output of the flip-flop 65, the output of the flip-flop 62, the output of the effective scanning data forming circuit C, and the output of the effective sampling pulse forming circuit. The outputs are (1), (IV), (V), (■) in Figure 13.
As is clear from the above, when all the values are rHl, that is, when the mark placed in the needle selection unit number setting field 1s is detected after the search mark 36 is detected as described above, As shown in (2), one pulse is output, and the flip-flop 65 is reset by this pulse.

Therefore, the Noritsubu flop 65 stores the fact that the search mark 36 has been detected as shown in [■] only until the mark in the needle selection unit number setting column 1s is detected.

In addition, the above-mentioned one pulse also controls the above-mentioned card feeding and scanning instruction circuit C81 and the same control circuit SC as will be described later.

On the other hand, as described above, the pulse (L) from the AND gate 63 from which the pulse for sampling the search mark 36 has been removed is sent to the hexadecimal-binary counter 67, specifically, the pulse (IV) directly counted by the hexadecimal-binary counter 67. Counting is performed by a counter consisting of a hexadecimal counter and a binary counter that converts the count of the hexadecimal counter into a binary number, and the count value of the counter 67 advances by one every time six pulses (IV) are counted. It looks like this.

The count value of this counter 67 is the output of the above AND 66 [
When the mark in the number of needle selection units setting field 1s is detected by the gate network 68 which uses [ ] as the gate operation signal, it is written into the memory 69 that stores the numerical value of the number of needle selection units; It is designed to be remembered.

This memory 69 stores the output of the flip-flop 65 [■
], that is, when the search mark 36 is sampled.

Further, the count output of the counter 67 is
Whether the number of pulses (IV) from 3 is within 120 or 1
It is input to a gate network 70 which discriminates whether the number is 21 or more.

This gate network 70 performs the above discrimination using a logic circuit consisting of a combination of parallel output gates from the counter 67. If it is within the above 120, as shown in (X), from the hanger terminal "1" AND gate 711 produces an output
If it is equal to or greater than l-12ij, an output is generated from the output terminal "2" and the AND gate 711 is opened.

Therefore, the AND gate 711 outputs 120 pulses for sampling the knitting pattern as shown in (Xll), and the AND gate 71□ outputs [■
], four pulses for sampling the function mark are output.

The 120 pulses from the AND gate 711 are input to a pulse selection circuit 72, where they are divided into eight types of pulses.

That is, the pulse selection circuit 72 has its "1" output system passing through the 120 pulses as shown in (XI), and its "2" output system is a T-type filter. It includes a flop flop and an AND gate connected to this output side, and as shown in [X■], 120
The even-numbered pulses are thinned out and the remainder is output, and the "3" output system is
It includes a ternary counter and an AND gate connected to this output side, and as shown in (XV), out of 120 pulses, the 3n-1 (where n is an integer) pulse is left and the others are thinned out. It has become.

On the other hand, the output of the memory 69 which stores the number of needle selection units programmed in the needle selection unit number setting field 1s in the card 1 as described above is the same as the above three types output from the pulse selection circuit 72. Gate network 73 for selecting which of the pulses is actually used as a sampling pulse
If the number of needle selection units is between 6 and 36,
An output is generated from the output system "3" of the gate network 13, the AND gate 743 is opened, and one of the three types of pulses [XV
] is designed to pass through the OR 75, and if it is between 42 and 60, an output is generated from the output system "2", opening the gate door 42, and the pulse (XIV) is passed through the OR 75. If it is between 66 and 120, an output is generated from the output system of "1", the AND gate 141 is opened, and the pulse of (XI) passes through the OR 75. It has become.

In this way, the sampling pulses for sampling the knitting pattern are divided into three types, and the pulses are selectively extracted depending on the number of needle selection units. The number of witness grid rows in the knitting pattern entry field 1p is 36, and the number of needle selection units is 6, 12, 18, 24, 3.
In addition to the cards that can be selected as 0.0 and 36, as shown in FIG. And as shown in Figure 20, the number of witness grid rows is 120 and the number of needle selection units is 6.
6.72,78,84,90,96゜102.108,
This is because a total of three cards, which can be selected as 114 and 120, are used depending on the number of needle selection units.

Incidentally, when the card 1 shown in FIG. 2 is used, the pulses output from the OR 75 are a total of 40 pulses shown in FIG. 13 (XV, l), which are explained in FIG. This output is input to the memory control circuit MC and the write address designation circuit WA, thereby generating the output of the effective scanning data forming circuit C (the output when the scanning sensor C scans the card 1 along the p27p2 line in FIG. 13). (shown in (■)), and the output related to the scanning of the knitting pattern entry field 1p is converted into a digital electrical signal corresponding to the knitting needles in a one-to-one relationship as shown in (XVI). , [X■], the address designation operation of the write address designation circuit WA causes the data to be sequentially stored at a certain fixed address in the memory IJMEM.

The digital electrical signals are stored in the memo IJMEM for all of the input grids in the first row of the knitting pattern entry field 1p from the left edge to the right edge as described above, but their readout is performed only when the selection is made. This is repeated only for the number of needle selection units set in the number of needle unit setting field 1s. The numerical output is converted into a binary number by a code converter 76 and is input to a read address designation circuit RA, which will be described later.

On the other hand, four pulses [■] for function mark sampling are output from the AND gate 712.
are separated from each other by a pulse discrimination circuit 77 composed of a gate group.

That is, the four pulses are counted by the counter 78, which causes the decoder 79 to calculate (xvi) according to the number of pulses.

As shown in [X■], outputs are generated from the output systems "l" to "4", respectively, and the gates in the pulse discrimination circuit 77 are opened, thereby "1" of the pulse discrimination circuit 77
~The output system of "4" is (XX).

As shown in (XXt), outputs are produced sequentially in accordance with the order of the pulses.

The four pulses separated by the pulse discrimination circuit 77 are input to a function memory circuit 80 composed of a D-type flip-flop, etc., and the output [■] from the effective scanning data forming circuit C is sampled here. is performed for each entry grid row in the function mark entry field 1f, and the sampled data is
] As shown in ], each story grid is stored separately.

Then, “1” to “
r I J , l-2J of the four output systems of ``4''
The output of ``1'' is input to the aforementioned card feeding and scanning control circuit SC, which will be explained in detail later, and the output of ``1'' controls the forward feeding of card 1, and the output of ``2'' controls the forward feeding of card 1. It is designed to control directional feed, and furthermore, "3", "
The output of "4" is input to the above-mentioned function drive circuit FD to control required function operations other than card feeding.

Next, the card feeding and scanning instruction circuit C8 and the same control circuit S
The specific configuration of C will be explained with reference to FIGS. 14 to 16.

The above-mentioned clear button CB is used not only in case of incorrect organization as mentioned above, but also as a kind of start button to start the organization when starting the organization using card 1. Before explaining the operations caused by this, an outline of how to use the hand knitting machine will be explained.

First, operate the carriage in the usual manner to perform the necessary knitting such as waste knitting, and when the knitting is completed to the point where the pattern is to be added, the carriage Y is set on the left and right of the knitting needle group set at the needle selection receiving position on the needle bed It is stopped outside one of the ends.

In this state, the card 1 is fed manually, that is, by turning the ratchet wheel 14 by hand, and set so that the upper and lower intermediate portions of the search mark 36 face the scanning sensor C of the scanning member in its original position. I'll keep it.

After that, press the middle clear button CB, card 1
is transferred one pitch in the forward or reverse direction (the direction at this time is not determined as will be explained later), and then the scanning member travels along the pl-β1 line shown in FIG. During the working process, after the number of needle selection units is set as described above, forward transport of the card 1 is restarted upon completion of the backward movement.

This transfer continues intermittently until the lowermost feed control mark 34 is detected by the scanning sensor C, and upon that detection, it stops and the scanning member is immediately moved. When the robot travels back and forth along the route and returns to the original position, the series of operations performed by operating the clear button CB ends.

After that, perform the necessary work for pattern knitting, such as inserting the desired colored thread into the thread opening of the carriage Y, and then move the carriage Y to the left and right switch activation pieces 3 installed on the needle bed
If the card 1 is repeatedly run back and forth until it exceeds 1.3r, the card 1 can be fed step by step and knitted in the knitting pattern drawn on it.

Now, when the clear button CB is operated, the accompanying signal (Fig. 15 [I]) is inverted at knot 81, passes through or 82, and is inverted again at knot 82' (II
), is output as a card feeding and scanning instruction signal from the card feeding and scanning instruction circuit C8, and is sent to the R-S flip-flop 83 for instructing card feeding and the R-S flip-flop 84 for instructing scanning member forward movement in the control circuit SC. It is designed to be set.

By setting the flip-flop 83, its Q output (1)
is applied to a card feed drive control circuit 86 consisting of a gate network through an AND 85, and is applied to either the output terminal "l" on the forward direction sending side or the "2" output terminal on the reverse direction sending side of this control circuit 86. On the other hand, for example, one pass shown in (V) is generated from the output terminal "2", and the aforementioned card feed drive circuit CD is driven, and the pair of electromagnets 16 and 16' for the card feed is activated. Either one of them is activated to transport the card 1 either in the forward direction or in the reverse direction.

This transfer is performed by the search mark 3 on card 1 as described above.
When the upper and lower intermediate portions of the scanning member 6 are opposed to the scanning sensor C of the scanning member, scanning is performed by a predetermined one pitch.

That is, the card feed drive control circuit 86 drives the card feed drive circuit CD using an output pulse from a timer 87 that determines the feed amount for one pitch of the card 1, and the output pulse is applied to a D-type flip-flop. The flip-flop 83 is reset by the rise of the output (IV) of the flip-flop 88.

Further, the output of the effective scanning data forming circuit C is input to the D terminal of the above-mentioned flip-flop 88, and the flip-flop is connected to the right limit switch which is the scanning member reversal position detecting means. 33r
Further, the timer 87 includes an oscillator such as an unstable multi-by-break and a binary counter that counts the oscillation signal, and the output of the counter is counted for a predetermined period of time. In addition, the counter is reset by the rLJ output (IN) of the flip-flop 83.

The D-type flip 70 knob 88 is designed to sample and output the input from the D terminal using the rising edge of the input pulse from the T terminal, and the timer 87 is activated by operating the clear button CB as described above. When the card 1 is sent by one pitch, the retrieval mark 36 has not yet crossed the scanning line of the scanning sensor C either above or below, so the D terminal of the flip-flop 88 is An rHJ output indicating that a mark has been detected is input from the effective scanning data forming circuit C, and the flip-flop 83 is reset by the output of the flip-flop 88.

Therefore, the timer 87 stops operating after outputting only one pulse, and the card 1 is only sent one pitch.

By the way, when the clear button CB is operated, the R-S flip-flop 89 is set, and its output causes the feed direction reversal circuit 90 to be set for the set time, that is, until it is reset by the right limit switch 33r.
is controlled to switch the output operation of the card feed drive control circuit 86 and transport the card 1 in the opposite direction. In the above state, if the clear button CB is pressed When operated,
Since it is not determined whether the R-S flip-flop 91, which indicates the direction in which the card 1 is to be transported, is in the set state or not, it has not been determined in which direction the one-pitch transport will be carried out.

When this one-pitch transfer is completed, the scanning member moves forward.

That is, when the clear button CB is operated, the scanning member forward movement instruction flip-flop 84 is set as described above, and its Q output is input to the AND 92; Since the signal obtained by inverting the Q output of the flop 83 with the knot 93 is input, when the flip-flop 83 is being set, that is, when the card 1 is being transferred, the output of the AND 92 is output from the above-mentioned scanning member drive circuit. The SD is not driven to move the scanning member forward, but only when the card 1 is stopped.

This forward movement ends when the flip-flop 84 is reset by the right limit switch 33r as shown in FIG. 15 (XI), and at the same time, the R-S flip-flop 94 for instructing the scanning member to move backward is set. As a result, the scanning member immediately begins to move back.

This backward movement is caused by the limit switch 33 on the left side of the scanning member.
However, since the scanning member collides with the limit switch 331 at a considerable speed, the reaction causes the limit switch 331 to be turned on.
31 may chattering as shown in FIG.
The home position return signal from 31 is delayed as shown in FIG. 16 [X■] and resets the flip-flop 94 as shown in FIG. , even after reaching the left stroke end, a force is applied to cause the shaft to warp further to the left, thereby preventing the above-mentioned fear.

As described above, when the scanning member reciprocates by operating the rear button CB, during the forward movement, the needle selection unit number setting field 1s is activated by the needle selection unit number setting circuit NS as described above.
The number of needle selection units programmed in the unit is electrically set, and when the setting is done, one pulse is sent from the needle selection unit number setting circuit NS (more specifically, the number of needle selection units 64'). (FIG. 15 (Vl)), the R-S flip-flop 9 in the card feeding and scanning instruction circuit C8
CI).

However, the card feed drive control circuit 86 is configured such that the signal from the leftmost limit switch 331 can be inputted through the knot 91, and the card feed drive control circuit CD is activated only when the scanning member is in the original position. of,
Since the card 1 is driven, the card 1 is not transferred while the scanning member is running after the number of needle selection units is set.

When the scanning member returns to its original position, the flip flop 8
3 has already been set as described above, the pulse of the timer 87 is input to the card feed drive control circuit 86, and the card 1 is transferred.

At this time, the transfer direction is set by the one pulse from the needle selection unit number setting circuit NS which sets the flip-flop 91 which instructs the card feed direction via the OR 98, and by the operation of the clear button CB. Since the flip-flop 89, which had previously been reset, has been reset by the right limit switch 33r, the Q
The output is directly applied to the card feed drive control circuit 86 through the feed direction inversion circuit 90, and a pulse is output from the "1" output terminal as shown in [■].
It is forward direction.

The feed direction reversing circuit 90 is composed of two exclusive OR circuits, and when the output of the flip-flop 89 is "L", the input from the flip-flop 91 is directly inputted to the control circuit 86, and vice versa. When the output is "H", the above input is inverted, and the flip-flop 91 has a Q output of "H" when set.
This instructs to forward the card 1, and when the reciprocal output at the time of reset becomes rHJ, it instructs to forward the card 1 in the reverse direction.

First, one pitch of the card 1 is transferred, but at that time, the scanning sensor C is still detecting the search mark 36, so the card is detected by the output (IV) of the D-type Flinopf west knob 88. The sending flip-flop 83 is about to be reset.

However, since this flip-flop 83 has priority over the set signal, and the flip-flop 96 supplying the set signal receives the output [X] of the AND 99 due to the subsequent detection of the search mark 36. Since it is not reset (reset by a falling edge) due to the output of the effective scanning data forming circuit C that has passed, the set state is still maintained, and the card 1 is continuously and repeatedly transported in the forward direction intermittently.

When the search mark 36 is moved away from the position facing the scanning sensor C due to such forward movement, the flip-flop 96 is reset at that moment, and the set signal to the card feeding flip-flop 83 disappears, but the flip-flop 83 is reset. Since the input to the D terminal of the D-type flip-flop 88 (output of the effective scanning data forming circuit C) also corresponds to the no mark, (IV
, l, the output of the D-type flip-flop 88 does not reset the flip-flop 83, and the flip-flop 83 still maintains the set state.
The card 1 continues to be transported in the forward direction even in the unmarked section where the search mark 36 is removed.

When the lowermost one of the feed control marks 34 is detected by the scanning sensor C due to the continuous forward movement, the D-type flip-flop 88 sets the flip-flop 83.
Transfer of card 1 is stopped.

At the same time, the Q output (xm) of the flip-flop 84 for forward movement of the scanning member, which is in the set state by operating the clear button CB as described above, is transmitted to the scanning member drive through the AND 92 by resetting the flip-flop 83. By inputting it to the circuit SD, the scanning member b moves back and forth, the scanning sensor C scans the card 1 along the line p2-p2 in Fig. 13, and when it returns to its original position, the scanning member b stops. , thereby also completing the above-described series of operations performed by operating the clear button CB.

It should be noted that a digital electrical signal (see FIG. 13 (XIV)) representing the knitting pattern obtained by the first one-stage scanning is
) is so limited that it is simultaneously written to both of the two storage units of the memo IJMEM, but its structure is not shown.

The first scanning of the knitting pattern entry field 1p and function mark entry field 1f of card 1 is automatically performed by operating the clear button CB as described above, but subsequent scanning is performed automatically by operating the clear button CB. This is automatically performed for each stage by reciprocating the carriage Y, which will be explained next.

11. When the carriage Y reverses its travel. The output of the carriage traveling direction detection switch e1 in the carriage reversal switch mechanism E (Fig. 16 [■]) is reversed from rHJ to rLJ or vice versa, but this reversal is due to knots and two It is detected by a carriage reversal detection circuit 100 including a differential circuit and a NOR, and from that,
The signal shown in 1) is output, the carriage inversion storage flip-flop 101 is set, and the fact that the carriage Y has been inverted is stored.

When the carriage Y enters the effective needle selection range divided by the left and right switch activation pieces 31 and 3r by running after this reversal, as described above, the effective needle selection range indication switch part e3
Since the output of ``H'' becomes "H" as shown in FIG. After this signal passes through the orer 82 and is inverted as shown in [IVI] at knot 82', it is output as a card feeding and scanning instruction signal from the card feeding and scanning instruction circuit C8, and the control circuit The flip-flops 83 and 84 in the SC [■].

It is designed to be set as shown in (XI).

By the way, since the output of knot 82' is also used as a reset signal for the flip-flop 101, the flip-flop 101 is reset the moment the output of knot 82' occurs, and as a result, AND102/not The output of 82' becomes a trigger waveform as shown in (VL (Vl)).

By setting the flip-flop 83, the pulse (Vl) from the timer 8T passes through the "1" output terminal of the card feed drive control circuit 86 as shown in [■], as in the case of operating the clear button CB described above. is input to the card feed drive circuit CD, and its first pulse (VI,
)l is first sent in the forward direction by one pitch, but because this one pitch movement causes the feed control mark 34 to miss the scanning sensor C, the output [) of the effective scanning data forming circuit C becomes a no mark. It corresponds to the above-mentioned type flip-flop 8.
8 fails to reset the flip-flop 83, the next pulse is output from the timer 87, and the card 1 is further transferred by one pitch.

When the card 1 is transferred in this way and the next feed control mark 34 is detected by the scanning sensor C, the flip-flop 83 is reset and the transfer of the card 1 is stopped. The Q output of the scanning member forward movement instruction flip-flop 84 (
XI) is input to the scanning member drive circuit SD via the AND 92 as shown in (XIV), so the scanning member moves forward immediately after the transfer of the card 1 is stopped, and the right limit switch 33r is turned on. When this happens, the output (XV) resets the flip-flop 84, and instead, the flip-flop 94 for instructing the scanning member to move back is set, causing the scanning member to move back and stop when it reaches its original position. , after completing one stage scanning of the card 1, the carriage Y is moved to the left and right switch activation pieces 31.3.
Every time card 1 is moved leftward or rightward from outside the range of r to within the range, card 1 moves to the feed control mark 34...
The scanning sensor C scans each stage automatically.

Note that the output of "1" from the function storage circuit 80 in the function discrimination circuit FS (when a mark is applied to the leftmost witness grid row among the four witness grid rows in the function mark entry field 1f) The output of "2" sets the flip-flop 91 for instructing the feed direction via the OR 98, and the output of "2" (a mark is placed in the second witness grid row from the left edge) is set. The output (output when the card was applied) is reset, and by marking any witness grid in the above two witness grid rows, it is possible to decide whether card 1 is to be sent forward or backward. can be controlled arbitrarily.

Further, when the above-mentioned stop button SB is operated, the card feed drive control circuit 86 is reset.
Even when the carriage Y is moved back and forth as described above, the card 1 is not transferred and only the scanning member is moved.

Therefore, when the stop button SB is operated,
The card 1 is repeatedly scanned in the same row, and one aspect of the knitting pattern in that row can repeatedly knit a continuous pattern.

Furthermore, the AND 102 generates the output shown in FIG. 16(V) when the special function button W is not operated, and as a result, card feeding and scanning are performed so that the carriage Y is left and right within the effective needle selection range. It is designed to be performed in the same way no matter which direction you enter.
When button W is operated, an output is generated from another AND 103 only when the carriage Y is reversed from the left row to the right row and enters the effective needle selection range from the right. It is designed for feeding and scanning.

Furthermore, the clear button CB functions as a kind of start button when starting the scanning of card 1 as described above, but if it is operated during the scanning stage of the knitting pattern, each time the clear button CB is operated, card 1 is It is possible to transfer only one step in the opposite direction from the previous step,
This is clear from the above.

The input function section described above transfers and scans the card 1, and the knitting pattern drawn in the knitting pattern entry field 1p is read one by one row by row, and the knitting pattern corresponding to the knitting needle N in a one-to-one relationship is digitalized. Memo IJM as an electrical signal
This is stored in the EM, and next, the digital electrical signal stored in this memo IJ M EM is read out at the same time as the carriage Y is moving within the effective needle selection range. Accordingly, the output function portion of the left and right knitting needle sorting mechanisms Fl and Fr for sorting the knitting needles N will be explained with reference to FIGS. 17 and 18.

When the carriage Y enters the effective needle selection range, the effective needle selection range indicating switch part e3 of the carriage reversal switch mechanism E outputs a signal "H" as shown in FIG. 18 [■] while traveling in the effective needle selection range. When the signal is output, the read address designating circuit RA is in the set state only during the output.

This read address designation circuit RA includes an up/down counter, and is configured to count timing pulses CI input from the timing pulse generators H1 and Hr each time the carriage Y travels by one pitch of knitting needles. However, the counted value is based on a parallel binary signal (more specifically, the first
By inputting the output of the code converter 76 shown in FIG. At the same time, the switching of addition and subtraction is performed by a signal (II) representing the carriage running direction from the carriage running direction detection switch section e1, and the timing pulse is added according to the carriage running direction. Or it is supposed to be subtracted.

Thus, the read addressing circuit RA
Each time the preset number of timing pulses is counted while running within the effective needle selection range, (Vl)
The same value (parallel binary electrical signal) will be taken repeatedly as shown in .

In other words, it can be said that this circuit RA encodes the knitting needles N between the left and right switch activation pieces 31 and 3r, and assigns repeat numbers to them in a certain direction.

The output of this circuit RA is supplied to the memory control circuit MC as a read address designation signal for the memory MEM, and the signal [■] indicating the carriage traveling direction is supplied to the memory control circuit MC. The digital electrical signal stored in the memo IJMEM is input to the control circuit MC as a signal that determines which of the two storage parts of the memo IJMEM is to be read. In this example, it is from 0 to 1 for the storage part corresponding to the running direction of Y.
The 12 pits of 1 are repeatedly read out, and as shown in (X), they are output as binary electrical signals from the memory control circuit MC and input to the waveform processing circuit WP.

The waveform processing circuit WP receives the signal [■] from the effective needle selection range indicating switch section e3, and only during the (H) period, the electromagnet drive circuit treats the signal from the memory control circuit MC as valid. MD, and the output of this drive circuit MD is input by the electromagnet changeover switch e2 to the electromagnet 46 of the knitting needle sorting mechanism Fl or Fr, which is the one that performs the effective sorting operation. It has become.

In this way, the knitting needles N between the left and right switch activation pieces 31 and 3r are grouped into 12 needles as shown in [■].
Sort according to the aspect of the knitting pattern drawn between the leftmost witness grid and the 12 witness grids on the right side of the knitting pattern entry field 1p (for example, in Fig. 18, the oval indicated by the solid line is forward-biased, The filled-in area is the backward deflection, and the oval shown by the broken line is the rest position l where the needle is not affected by the needle selection action.
(to indicate something) will be done.

By the way, as mentioned above, the knitting pattern entry column 1p is scanned over the entire length of its left and right ends, and all the bits of the digital electric signal obtained by the one-stage scanning are stored in the memory MEM, and are read out from there. The number of bits is determined by the number of needle selection units programmed by marking the number of needle selection unit setting field 1s. For example, if it is set to "12", even if the left Even if a knitting pattern is recorded on the right side of the 12th witness grid, the recorded part on the right side is scanned and temporarily stored in the memo IJMEM, but it is not a signal for needle selection. It will never be read as .

With the above configuration, it is possible to knit a unit pattern according to the knitting pattern on the card 1, but the main hand knitting machine can also knit the pattern actually knitted without changing the knitting pattern. can be changed by manual operation of the manual operation member on the operation panel 2, which will be explained next.

The left/right pattern selection means RL changes the output electric signal as shown in FIG. 18 (IV) by switching its manual operation section.
The signal is inverted from "H" to "L" or vice versa as shown in (XIII), and the signal is connected to the signal (1) representing the carriage running direction and the comparator circuit CO.
It is now possible to compare (exclusive OR) with
The comparison signal [■] specifies the addition/subtraction direction of the up/down counter of the read address designating circuit RA.

Therefore, the count value of the read addressing circuit RA is determined by the above-mentioned C Vl ) when the carriage Y travels in a certain direction.
It is decided based on the operation of the pattern left/right selection means RL whether to take the relationship of (V) or [X■].
In the case of l[) and (XV), the pattern to be knitted has a relationship as if the left and right sides were reversed.

Next, the pattern mode selection means MS changes from "L" to "H" as shown in (XI) by switching the manual operation section.
Alternatively, the means M outputs an electrical signal that is inverted and supplies it to the waveform processing circuit WP.
The operation of S determines whether the waveform processing circuit WP passes the input (X) from the memory control circuit MC without inverting it or inverts it as shown in [■].

Therefore, by operating this means MS, the front and rear sorting mode of the knitting needles N can be reversed, and thereby the card 1
This allows the ground pattern of the knitted pattern to be reversed without changing the knitting pattern above.

Furthermore, when the clear button CB is operated, the memory control circuit MC clears the stored contents of the memo IJMEM.

Although one embodiment of a hand knitting machine to which the present invention is applied has been described above, the present invention is not limited to this.

That is, in the above embodiment, all bits of digital electrical signals related to one stroke scanning of the scanning member b are stored in the memo IJM.
Unit pattern knitting was carried out by storing it in EM and reading it for the set number of needle selection unit bits, but at the stage of storing it in memo IJMEM, the bits of the digital electric signal stored in it are Substantially the same result can be achieved even if the number is set for the number of needle selection units set above and all of them are read out.

In addition, in the above case, by fitting the coil 31 of the scanning member into the guide rod 28 and passing currents of opposite polarities through it, magnetic forces in opposite directions on the left and right sides are applied to the coil 31 using the permanent magnet 32 as a stator. The scanning member was caused to reciprocate by using two coils whose winding directions were opposite to each other.
Moreover, the guide rod 28 is made of a magnetic material so that current is passed alternately through two coils, and the coil and the guide rod 28 are made of a magnetic material.
Even if a magnetic force is generated between the scanning member and the scanning member, the scanning member can be moved back and forth.

In this case, the guide rod 28 functions as a guide means for guiding the movement of the scanning member, and at the same time functions as a stator of the linear motor.

Further, in the above description, the card 1 is driven by the electromagnets 16 and 16', but a pulse motor may also be used.

Furthermore, in the above, a card in which one witness lattice corresponds to one stitch is used as the knitting program card 1, but a card in which one witness lattice corresponds to a predetermined plurality of stitches may also be used. A card on which a pattern, function mark, and needle selection unit number setting mark are printed in advance may be used.

Furthermore, the knitting pattern and the above marks can be created by filling in the card surface, or by pasting colored paper of the desired shape onto the card, and can be read in the same way as above. It is.

Furthermore, it is clear that the information for setting the number of needle selection units and the information for searching for the same can be formed by marking as in the embodiment, or even if it is formed by drilling, it can be detected as an electrical signal. be.

As is clear from the above, the uninvented knitting information recording medium includes a knitting pattern recording section for recording a knitting pattern representing a pattern to be knitted, and a number of needle selection units for indicating the number of needle selection units. A selected needle unit number setting section is formed for recording information, and search information instructing that the selected needle unit number information should be read is provided at a predetermined position for this selected needle unit number setting section. In addition to the knitting pattern representing the pattern to be knitted, information instructing the number of needle selection units can be recorded in a program on the same recording medium, and the information can be read and distinguished from the knitting pattern without being confused with the knitting pattern. I can do it.

Further, the configuration information reading device of the present invention reads the knitting pattern/needle selection unit number information recorded on the knitting information recording medium and its search information as an electric signal using the same scanning member.
The electrical signal related to reading the knitting pattern is sampled with a sampling pulse to generate a digital electrical signal, and the number of needle selection units is determined by the number of sampling pulses between the reading of the search information and the reading of the needle selection unit number information. This device obtains a digital electrical signal representing the knitting pattern and the number of selected needle units, and can read both the knitting pattern and the information on the number of selected needle units as digital electrical signals. The pattern can be efficiently read using the same reading mechanism (scanning member and sampling device) that reads the pattern.
