Description

  The present invention relates to an improvement in a magnetic recording / reproducing apparatus, a slip printer with a magnetic recording / reproducing apparatus, and a magnetic recording / reproducing method.

  As a magnetic recording / reproducing apparatus equipped with a magnetic head for reading and writing magnetic information from a magnetic recording medium attached to a sheet or a slip printer with a magnetic recording / reproducing apparatus, for example, as disclosed in Patent Document 1 Such a magnetic recording / reproducing apparatus, a magnetic stripe reading / writing mechanism as disclosed in Patent Document 2, a passbook / certificate issuing apparatus as disclosed in Patent Document 3, and the like are already known.

  In the magnetic recording / reproducing apparatus disclosed in Patent Document 1, an opening is provided in a guide plate that supports a sheet of paper such as a passbook from the lower surface side, and a magnetic head is provided below the guide plate so as to protrude upward from the opening. The magnetic head is pressed against the lower surface of the book by pressing the tip of the magnetic head to read and write magnetic information from the magnetic recording medium. Depending on the structure, depending on the carrying direction of the passbook or the moving direction of the magnetic head In such a case, there is a possibility that the end of the passbook is caught by the magnetic head.

  Further, the magnetic stripe sticking pattern used as a magnetic recording medium by sticking to a paper such as a passbook is a horizontal type as shown in FIGS. 13 (a) to 13 (b). 13 (c) to 13 (f) as shown in FIG. 13 (f). The magnetic stripe on the passbook 100 can be the same horizontal type or the same vertical type. There are various standards for the sticking position 101 depending on the issuer of the passbook.

Among them, the magnetic recording / reproducing apparatus disclosed in Patent Document 1 includes a magnetic stripe 101 orthogonal to the conveyance direction of the passbook 100, for example, as shown in FIGS. 13 (a) to 13 (b). It is configured on the assumption that the bankbook 100 is handled, and the relationship between the guide plate 102, its opening 103, the conveyance direction of the bankbook 100, and the movement direction of the magnetic head 104 is as shown in FIG. Yes.
That is, in FIG. 12, the bankbook 100 is conveyed from right to left, and the magnetic head 104 is moved in the direction perpendicular to the paper surface.
The tip of the magnetic head 104 is formed with a tapered surface for reliably contacting the tip of the magnetic head 104 over the entire width with the magnetic stripe 101. This tapered surface is used when reading and writing magnetic information. It is formed so as to protrude upward along the moving direction of the magnetic head 104 with respect to the bankbook 100, that is, to protrude upward in a plane orthogonal to the paper surface of FIG. 12 and the guide plate 102 in FIG. Therefore, when viewed from the moving direction of the magnetic head 104, that is, the direction orthogonal to the paper surface of FIG. 12, the tip of the magnetic head 104 has a planar shape as shown in FIG. 12, and corners are formed on both left and right sides thereof. Therefore, there is a possibility that the tip of the bankbook 100 is caught by the magnetic head 104 when the bankbook 100 is transported.
Since the home position of the magnetic head 104 is usually determined at one end in the width direction on the guide plate 100 orthogonal to the conveyance direction of the bankbook 100, when the end of the bankbook 100 is caught by the magnetic head 104. The posture of the passbook 100 may change carelessly, for example, it may be tilted in the direction α in FIG. 13A. In such a state, the magnetic head 104 is orthogonal to the conveyance direction of the passbook 100. Even if it is moved, the magnetic head 104 cannot be moved properly along the center of the magnetic stripe 101, and the magnetic information cannot be read or written normally.

On the other hand, assuming that the bankbook 100 as shown in FIGS. 13 (c) to 13 (f) is handled, the relationship between the guide plate 102, the opening 103, and the conveyance direction of the bankbook 100 is shown in FIG. Such a magnetic recording / reproducing apparatus is known.
In such a configuration, normally, the magnetic head 104 does not move, and magnetic information is read from and written to the magnetic stripe 101 using the relative movement between the passbook 100 and the magnetic head 104 that occurs when the passbook 100 is transported. It is like that.
In FIG. 11, the conveyance direction of the bankbook 100 is from right to left, and therefore the relative movement direction of the magnetic head 104 with respect to the bankbook 100 is from left to right.
As shown in FIG. 11, in the configuration on the premise that the magnetic head 104 is relatively moved in the carrying direction of the passbook 100, the tapered surface of the tip of the magnetic head 104 is in the carrying direction of the passbook 100 as shown in FIG. Therefore, the possibility that the tip of the bankbook 100 is caught by the magnetic head 104 is low.
However, as already described, since the magnetic head 104 does not move in the direction perpendicular to the paper surface of FIG. 11, the magnetic head 104 always comes into sliding contact only with a specific position in the width direction of the bankbook 100, and the magnetic stripe 101 is located at this position. Unless it is attached, magnetic information cannot be read or written.
That is, by specifying the specifications of the magnetic recording / reproducing apparatus, it is possible to deal with the passbook 100 having any one of the specifications shown in FIGS. 13C to 13F, but dealing with the passbook 100 having other specifications. There is a problem that can not be.
Even if the bankbook 100 to be handled is specified, the bankbook 100 must be positioned and inserted into the paper insertion slot so that the magnetic stripe 101 of the bankbook 100 is in sliding contact with the magnetic head 104. There is annoyance.
Since the width of the guide plate 102 is usually made larger than the width of the passbook 100 in order to facilitate the insertion of the passbook 100, for example, it is provided at the end of the guide plate 102 in the width direction. An operation of inserting the bankbook 100 while pressing the end of the bankbook 100 in the width direction against the side plate is necessary, which is troublesome.
In order to solve such a problem, it is also conceivable to move the magnetic head 104 in the direction perpendicular to the paper surface in the configuration as shown in FIG. However, in such a case, if the magnetic head 104 is simply moved in the direction perpendicular to the paper surface, the relative moving direction of the magnetic head 104 with respect to the bankbook 100 is the same as that of FIG. There arises a disadvantage that the corner is caught on the end of the bankbook 100.

Further, in the magnetic stripe read / write mechanism disclosed in Patent Document 2, the mounting position of the magnetic head 104 is set in a direction perpendicular to the conveyance direction of the passbook 100, that is, in several positions in the direction perpendicular to the paper surface in FIG. By changing to, a configuration for dealing with the passbook 100 having various specifications as shown in FIGS. 13C to 13F is proposed.
However, changing the mounting position of the magnetic head 104 requires complicated operations such as disassembling the casing of the magnetic stripe read / write mechanism and detaching the magnetic head 104. Naturally, such operations are performed by bank depositors and the like. Can't be done every time.
In other words, the magnetic stripe read / write mechanism disclosed in Patent Document 2 can adjust the magnetic stripe read / write mechanism in accordance with the specifications of each bank when the apparatus is delivered to a bank or the like, so that the apparatus has versatility. However, the single magnetic stripe read / write mechanism cannot deal with the passbook 100 having different specifications inserted by various users one after another.
Further, the magnetic head 104 is mounted by selecting one position from several predetermined mounting positions, and the mounting position is not completely free.
As a result, like the above-mentioned Patent Document 2, there is a disadvantage that it is not possible to deal with the passbook 100 of various specifications with a single device, and it is also impossible to deal with misalignment that occurs when the passbook 100 is inserted. .

On the other hand, the passbook / certificate issuing device disclosed in Patent Document 3 has a configuration in which a positioning side plate provided at an end in the width direction of the guide plate 102 is movable. It is possible to move the bankbook 100 in a direction orthogonal to the conveying direction by pressing the side edge of the bankbook 100 with a plate.
However, if the passbook 100 is forcibly moved in the width direction in this way, there is a high possibility that damage such as wrinkles and dirt will occur in the passbook 100 itself.
Further, even though the side plate can be moved and the end of the passbook 100 can be pushed, the end of the passbook 100 cannot be pulled. It is necessary to position the direction end against the side plate. In particular, when the end of the bankbook 100 in the width direction is greatly displaced from the side plate to a position closer to the center of the sheet conveyance path, there is a disadvantage that reading and writing of magnetic information cannot be performed at all.

Japanese Patent Application Laid-Open No. 2002-28891 (paragraph numbers 0032 and 0033) JP-A-9-245416 (paragraph number 0027) Japanese Patent Laid-Open No. 2-106373 (lower left column on page 2)

  Accordingly, an object of the present invention is to improve the inconveniences of the prior art, so that the tip of the magnetic head is not inadvertently caught on the paper or the magnetic recording medium, and various papers with different magnetic recording medium sticking positions. The present invention provides a magnetic recording / reproducing apparatus, a slip printer with a magnetic recording / reproducing apparatus, and a magnetic recording / reproducing method that can read and write magnetic information in response to the above-described problems and are not easily affected by a positional deviation when a sheet is inserted. .

The magnetic recording / reproducing apparatus of the present invention is a magnetic recording / reproducing apparatus provided with a magnetic head for reading and writing magnetic information from a magnetic recording medium attached to a sheet.
A guide plate that has a slit that allows the tip of the magnetic head to protrude over the entire width of the paper in a direction perpendicular to the paper insertion direction, and that supports the paper from the lower surface side. Guide means for guiding the horizontal movement of the magnetic head along the longitudinal direction of the slit in a plane parallel to the head, and feed means for feeding the magnetic head along the linear movement direction regulated by the guide means And a magnetic head lifting and lowering means for moving the magnetic head up and down in a direction protruding from the slit and a direction retracting downward from the slit,
The guide means is constituted by guide rods supported at both ends by the frame of the magnetic recording / reproducing apparatus ,
The magnetic head is attached to the carrier slidably fitted to the guide rod so as to be movable up and down .
The magnetic head lifting / lowering means includes a biasing means having a spring that constantly presses the magnetic head in the upward direction in the carrier, and the magnetic recording medium of the inserted paper is positioned at a slit on the guide plate. And forcibly returning means for moving the magnetic head to the lowered position against the pressing force of the spring until the magnetic head reaches the magnetic recording medium of the paper. It has a configuration.

With the above configuration, the magnetic head is moved in the longitudinal direction of the slit, that is, the direction perpendicular to the paper insertion direction, with the magnetic head retracted below the guide plate that supports the paper from the lower surface side. After positioning, the magnetic head can be protruded from the slit and brought into contact with the magnetic recording medium of the paper.
Therefore, the inconvenience that the end of the paper is caught by the magnetic head during the conveyance of the paper is solved. In addition, it is possible to deal with various types of paper with different magnetic recording medium attachment positions, and similarly, it is possible to cope with variations in the position of the magnetic recording medium caused by misalignment when inserting paper. Become.
Moreover, the magnetic head is attached to the guide rod serving as the guide means via the carrier, and only this magnetic head is moved up and down, so that the entire component including the guide rod is moved up and down compared to the case of moving the magnetic head. The structure of the magnetic head lifting / lowering means required for the vertical movement can be reduced in size and the energy required for the vertical movement of the magnetic head can be reduced .

  Furthermore, an accumulating means for urging the magnetic head in the upward direction in a state where the magnetic head is raised in the direction protruding from the slit may be provided.

  Since the tip of the magnetic head can be reliably pressed against the magnetic recording medium, magnetic information can be read and written accurately. When positioning the magnetic head, the magnetic head is fed with the magnetic head retracted downward, so even if the structure is such that the tip of the magnetic head is urged against the magnetic recording medium, There is no inconvenience that the end of the paper is caught by the magnetic head.

It may be configured such that the biasing means Ru also serves as the energy-storing means.

By adopting a configuration in which the magnetic head is lifted using a biasing means provided with a spring that constantly presses the magnetic head in the upward direction, the biasing means can be diverted as an energy storage means. As a result, the structure can be simplified as compared with the case where the accumulating means for pressing the tip of the magnetic head against the magnetic recording medium is provided independently of the urging means.

More specifically, the biasing means includes
Oscillation having a central portion rotatably supported by a shaft fixed in the carrier so as to be substantially parallel to the guide rod, and having one end pivotally attached to the lower end of the magnetic head A member,
With the axis as a center, the magnetic head can be configured by a spring that rotates and biases the swinging member in a direction in which the magnetic head rises.
The forced return means is
An elevating plate that has a sliding contact portion that is in sliding contact with the other end portion of the swing member, and that is disposed on the frame so as to be parallel to the guide rod, and at least allows the sliding contact portion to move up and down; ,
It can be configured by at least an elevating plate driving means for moving the sliding contact portion of the elevating plate up and down.

When such a configuration is applied, the swinging member pivotally supported at the center by the shaft in the carrier is rotated and biased by the spring, and the magnetic head pivotally attached to one end of the swinging member is raised. It is constantly urged toward the direction. Further, since the sliding contact portion of the lifting plate is in sliding contact with the other end portion of the swinging member, the other end portion of the swinging member is moved upward by raising the sliding contact portion of the lifting plate by the lifting plate driving means. When lifted, one end of the swinging member is lowered, and the magnetic head pivotally attached to this one end is lowered.
Since the elevating plate is arranged so as to be parallel to the guide rod, the vertical movement of the sliding contact portion of the elevating plate ensures that the carrier and magnetic head are located at any position on the guide rod. The head can be moved up and down.
As described above, a portion corresponding to the urging means in the magnetic head lifting / lowering means is provided on the carrier, and a part corresponding to the forcible return means, that is, a part requiring a drive source such as a motor and a solenoid is framed. By disposing it on the side, it is advantageous in terms of downsizing the carrier as a moving member and reducing the mass compared to the case where the forcible return means and its drive source are mounted on the carrier.
Further, since the drive source itself of the forced return means does not need to move with the carrier, failure factors such as disconnection of the lead wire are reduced, and the durability of the apparatus is improved.

Alternatively, the biasing means is
A parallel link mechanism provided between the carrier and the magnetic head, and a spring for changing the posture of the parallel link mechanism in a direction in which the magnetic head is raised,
The forced return means,
Oscillation having a central portion rotatably supported by a shaft fixed in the carrier so as to be substantially parallel to the guide rod, and having one end thereof slidably in contact with the upper surface of the parallel link mechanism A member,
An elevating plate that has a sliding contact portion that is in sliding contact with the other end portion of the swing member, and that is disposed on the frame so as to be parallel to the guide rod, and at least allows the sliding contact portion to move up and down; ,
You may make it comprise at least the raising / lowering plate drive means which moves the said sliding contact part of the said raising / lowering plate up and down.

When such a configuration is applied, the parallel link mechanism provided between the carrier and the magnetic head receives the force of the spring that changes the attitude of the parallel link mechanism, so that the magnetic head is directed upward. Will be energized. In addition, one end portion of the swinging member pivotally supported at the center by the shaft in the carrier is in sliding contact with the upper surface of the parallel link mechanism, and the other end of the swinging member is in sliding contact with the lifting plate. Since the sliding contact portion of the lifting plate is raised by the lifting plate driving means, the other end portion of the swinging member is lifted upward, and one end portion of the swinging member is lowered, and this one end portion Thus, the upper surface of the parallel link mechanism is pushed and the magnetic head is lowered.
As above, the elevating plate is arranged so as to be parallel to the guide rod, so that the magnetic head can be moved up and down reliably regardless of the position of the carrier and magnetic head on the guide rod. In addition, it is possible to reduce the size and weight of the carrier as the moving member, and there is no failure factor such as disconnection of the lead wire, thereby improving the durability of the apparatus.

Further, the above-described lifting plate is composed of a long plate-like body having a length comparable to that of the guide rod, and has a sliding contact portion that is in sliding contact with the other end portion of the swinging member on one side. It is pivotally attached to the frame around the side,
The elevating plate driving means includes
It is desirable that the driving mechanism is configured by swing driving means for swinging the sliding contact portion of the lift plate around the other side of the lift plate.

  Since only the sliding contact portion that slides in contact with the other end portion of the swinging member is actually required of the lifting plate, the sliding contact portion is provided on one side of the lifting plate made of a long plate-like body. It is possible to apply a simple structure such as installing and pivoting the other side and moving the sliding contact part up and down by the posture change caused by swinging of the lifting plate, and the structure is simplified compared to the case where a complicated linear motion mechanism is adopted. Manufacturing cost can be reduced.

  Further, it is desirable to provide a bearing that contacts the sliding contact portion of the lifting plate at the other end portion of the swing member.

  Since sliding resistance between the swinging member provided on the carrier side and the lifting plate provided on the frame side is reduced, the magnetic head is smoothly fed along the linear movement direction regulated by the guide rod. Can be hung.

And a shutter that protrudes and closes in the space between the slit of the magnetic head retracted downward from the slit of the guide plate and closes the slit, and the shutter is a partial circle with the slit-side surface convex upward An elongated plate-like body having an arc-shaped cross section, and arms at both ends in the longitudinal direction provided to hold the plate-like body swingably with a position below the slit as a swing center, The swing drive means for swinging the arm is such that the long plate-like body is located in a space between the tip of the magnetic head and the slit in a state where the magnetic head is retracted downward from the slit. Further, it the magnetic head is configured to swing said arm about said pivot center as plate-shaped body of the elongated so as to protrude from the slit is detached from the space Masui.

A direction perpendicular to the paper insertion direction to deal with various types of paper with different magnetic recording medium attachment positions, and also to deal with variations in the position of the magnetic recording medium caused by misalignment during paper insertion. For this reason, the length of the slit is inevitably longer due to the movement stroke of the magnetic head with respect to the magnetic head. It is possible to prevent the inconvenience of being caught on.
By applying a simple configuration in which the slit is opened and closed by a posture change caused by the swing of the shutter, the structure can be simplified and the manufacturing cost can be reduced .
In addition, by forming a long plate-like body that functions as a portion that closes the slit so as to protrude upward, this arc-shaped portion can be made to enter the slit by the swinging motion of the arm. Since the slit can be closed substantially on the same plane as the guide plate by the plate-like body having the arc-shaped cross section, the sheet can be more reliably prevented from being caught by the slit and the shutter .

  Further, the swing drive means for swinging the shutter arm and the swing drive means for swinging the elevating plate can be configured to cooperate with each other by a single drive source.

Both the movement required for the vertical movement of the sliding contact portion of the lifting plate and the movement required for opening and closing the shutter are oscillating movements, so that the movement of the lifting plate and the shutter is coordinated using a single drive source. The operation can be realized.
Link mechanisms, cams, etc. can be used to realize cooperative operation. By appropriately combining these mechanical elements, the swinging movement of the lifting plate and the opening / closing operation of the shutter are coordinated, that is, magnetic When the head is retracted downward from the slit (the sliding contact portion of the elevating plate is raised), the shutter plate is positioned in the space between the tip of the magnetic head and the slit to close the slit. In a state where the head protrudes from the slit (a state where the sliding contact portion of the lifting plate is lowered), the shutter plate can be separated from the space to open the slit.

The slip printer with a magnetic recording / reproducing apparatus of the present invention includes a magnetic recording / reproducing apparatus having any of the above-described configurations,
A sensor for detecting an end position of a sheet in a direction orthogonal to an insertion direction of the sheet carried on the guide plate;
Storage means for storing a separation distance from an end position of the paper to a sticking position of the magnetic recording medium;
The feed means is driven and controlled from the end position detected by the sensor in a direction perpendicular to the paper insertion direction by a distance corresponding to the separation distance, and retracted downward from the slit. The magnetic head in a state is positioned at the position where the magnetic recording medium is attached, and the magnetic head is moved in a direction protruding from the slit by the magnetic head lifting / lowering means to read and write magnetic information from the magnetic recording medium. And a control unit that drives and controls the feeding unit with the home position of the magnetic head as a movement target position after the magnetic head is retracted downward from the slit by the magnetic head lifting and lowering unit. Have

With the above configuration, the end position of the sheet in the direction orthogonal to the insertion direction of the sheet carried on the guide plate is detected by the sensor, and this end position is temporarily stored in the control unit. At this time, for example, a number line orthogonal to the paper conveyance direction is used as the coordinate system, and the edge position of the paper is detected using the position of the side plate provided at the edge in the width direction of the guide plate as the coordinate origin. To do. The sensor can be provided on the print head of a slip printer with a magnetic recording / reproducing device. In this case, the sensor is moved in a direction perpendicular to the paper insertion direction by feeding the print head when the paper is inserted. From the coordinate origin based on the amount of movement of the print head from the home position when the sensor detects the edge of the paper, specifically, the integrated value of the drive command pulse of the stepping motor that feeds the print head The distance to the edge of the paper can be obtained.
Then, the storage means is searched based on the specification of the paper, and a separation distance (specification corresponding to the paper) from the end position of the paper to the attaching position of the magnetic recording medium is obtained.
The target position to which the magnetic head should be moved is a value obtained by adding the distance from the end position of the paper to the sticking position of the magnetic recording medium to the distance from the coordinate origin to the end of the paper.
Then, the feeding means is driven and controlled with this position as the movement target position, and the magnetic head in a state of being retracted downward from the slit is positioned at the position where the magnetic recording medium on the paper is attached.
In particular, in the case of a slip printer equipped with a magnetic recording / reproducing apparatus having a shutter, the shutter inevitably closes the slit while the magnetic head retracts downward from the slit and moves in a direction perpendicular to the paper insertion direction. Therefore, it is possible to reliably solve the problem that the end portion of the paper carried on the guide plate is caught by the magnetic head and further the slit.
Then, when the positioning of the magnetic head is completed at the position where the magnetic recording medium is attached, the magnetic head lifting means is operated to move the magnetic head in the direction of protruding from the slit, and the tip of the magnetic head contacts the magnetic recording medium. The magnetic information is read or written from the magnetic recording medium in contact with the magnetic recording medium.
At this time, in the case of a slip printer having a magnetic recording / reproducing apparatus having a shutter, the shutter swings to open the slit as the magnetic head is raised.
When reading and writing magnetic information, in the case of a slip printer equipped with a magnetic recording / reproducing device corresponding to a sheet having a lateral type magnetic recording medium, the magnetic head is moved in a direction perpendicular to the inserting direction of the sheet by the feeding means. In the case of a slip printer equipped with a magnetic recording / reproducing device corresponding to a sheet having a longitudinal type magnetic recording medium, the sheet is fed along the sheet conveying direction to magnetize the magnetic head. This is done by moving relative to the recording medium.
When reading or writing of magnetic information is completed, the magnetic head lifting / lowering means is actuated again to retract the magnetic head downward from the slit, and further, the feeding means is driven and controlled with the home position of the magnetic head as the movement target position. Return the magnetic head to the home position. In the case of a slip printer equipped with a magnetic recording / reproducing apparatus having a shutter, the shutter swings to close the slit as the magnetic head is lowered.
The magnetic head returns to the home position in the lowered state, the slit is closed by the shutter, and the state of the slip printer with the magnetic recording / reproducing device returns to the initial standby state.

In the magnetic recording / reproducing method of the present invention, the paper is carried onto the guide plate with the magnetic head retracted below the guide plate that supports the paper from the lower surface side.
Detecting the edge position of the sheet in a direction orthogonal to the insertion direction of the sheet carried on the guide plate;
The insertion direction of the paper with a position moved in a direction orthogonal to the insertion direction of the paper by a distance corresponding to the separation distance from the end position of the paper to the attachment position of the magnetic recording medium on the paper The magnetic head is linearly moved along a slit formed in the guide plate in a direction orthogonal to the magnetic head to position the magnetic head at the movement target position ,
The magnetic head is projected from the slit and brought into contact with the magnetic recording medium of the paper to read and write magnetic information,
With the magnetic head retracted downward from the slit, the magnetic head is linearly moved along the slit to return to the home position.

The edge position of the paper is detected by detecting the edge position of the paper in a direction perpendicular to the insertion direction of the paper loaded on the guide plate with the magnetic head retracted below the guide plate that supports the paper from the lower surface side. The magnetic head is in the longitudinal direction of the slit, that is, the insertion of the paper, with the position moved in the direction perpendicular to the paper insertion direction by a distance corresponding to the separation distance from the magnetic recording medium on the paper to the attachment position of the magnetic recording medium. Since the magnetic head is positioned by moving it in a direction perpendicular to the direction, the magnetic head protrudes from the slit and comes into contact with the magnetic recording medium of the paper. The inconvenience of being caught on the magnetic head is eliminated, and it is caused by misalignment when inserting various types of paper with different magnetic recording media sticking positions and when inserting the paper. It has become possible to correspond to variations in the position of the magnetic recording medium.

  The magnetic recording / reproducing apparatus, the slip printer with the magnetic recording / reproducing apparatus, and the magnetic recording / reproducing method according to the present invention are configured so that the magnetic head is in the paper insertion direction with the magnetic head retracted below the guide plate that supports the paper from the lower surface side. Since the magnetic head is positioned by moving it in the orthogonal direction, the magnetic head protrudes from the slit and comes into contact with the magnetic recording medium of the paper. In addition, the magnetic information can be read and written by dealing with various types of paper with different magnetic recording media sticking positions, and further, misalignment when inserting the paper It is possible to read and write magnetic information without being affected by.

  Here, with reference to FIGS. 5 to 6, the structure of the biasing means 27 and the forcible return means 28 constituting the magnetic head lifting / lowering means 21 will be described in detail.

  First, the configuration of the carrier 16 corresponding to the horizontal bankbook 100 shown in FIG. 5 will be described.

  The urging means 27 of the carrier 16 corresponding to the lateral type bankbook 100 is rotatably supported at the center by a shaft 29 fixed in the carrier 16 so as to be parallel to the guide rods 18 and 19. The swinging member 30 whose one end is pivotally attached to the lower end of the magnetic head 13 and the swinging member 30 rotate in the direction in which the magnetic head 13 ascends around the shaft 29, that is, in the counterclockwise direction in FIG. And a spring 31 to be urged.

  Further, the forcible return means 28 is arranged on the frame 22 so as to be parallel to the guide rods 18, 19, and at least a sliding contact portion 33 a that makes sliding contact with a bearing 32 provided at the other end of the swing member 30. , An elevating plate 33 capable of moving up and down, elevating plate driving means 37 (see FIG. 3) for moving the sliding contact portion 33a of the elevating plate 33 up and down, and an inserter motor 34 (FIG. 2) functioning as the drive source And a swing driving means 35 (see FIG. 4A) for converting the rotation of the inserter motor 34 into a repetitive swing operation and transmitting it to the lift plate 33. The swing driving means 35 and the inserter motor 34 are part of the lifting plate driving means 37.

The elevating plate 33 is formed of a long plate-like body having a length comparable to that of the guide rods 18 and 19, and is provided on one side thereof, that is, on the right side in FIG. And a sliding contact portion 33a that is in sliding contact with the bearing 32.
The other side of the elevating plate 33 is bent into a substantially L-shape and fixed to the shaft 36, and is pivotally attached to the frame 22 with the shaft 36 as a center.

The rotation of the inserter motor 34 that functions as a drive source of the elevating plate driving means 37 is transmitted to the cam shaft 38 shown in FIG. 3 via a gear train (not shown), and the cam 39 fixed to the cam shaft 38 rotates.
Of the three links 40, 41, 42 constituting the swing driving means 35 (see FIG. 4A), the link 42 is provided with a cam follower 43 that contacts the outer periphery of the cam 39. With the change in the contact state between the cam follower 43 and the cam 39 accompanying the rotation of the cam 42, the posture of the link 42 that is constantly urged to swing clockwise by the spring 44 with its lower end portion as a fulcrum changes. The posture change is transmitted to the link 40 via the link 41, and the shaft 36 of FIG. 5 fixed to the link 40 rotates, and the lifting plate 33 fixed to the shaft 36 is moved to the other side, that is, in FIG. By swinging around the left portion, the sliding contact portion 33a of the lifting plate 33 located on the right side moves up and down.

  Furthermore, the magnetic recording / reproducing apparatus 2 in this embodiment includes a shutter 45 that appears and disappears in a space between the tip of the magnetic head 13 retracted downward from the slit 15 in the guide plate 5 and the slit 15 to open the slit 15. .

  As shown in FIG. 5, the shutter 45 includes a long plate-like body 45 a having a partial arc-shaped cross section in which the surface on the slit 15 side is convex upward, and a position below the slit 15 in a swing center. In order to hold the plate-like body 45a in a swingable manner, it is constituted by arms 45b, 45b provided at both ends in the longitudinal direction of the plate-like body 45a.

  The swing drive means 47 (see FIG. 4A) for swinging these arms 45b and 45b includes a shutter cam 48 (see FIG. 2) fixed in parallel with the cam 39 on the cam shaft 38 described above. A shutter link mechanism 46 (see FIG. 4A) that engages with an arm 45b provided at the end of the shutter 45 in the longitudinal direction, and an outer periphery of the shutter cam 48 attached to the end of the shutter link mechanism 46. It is comprised by the cam follower 62 which contact | abuts.

The configuration of the shutter link mechanism 46 is shown in FIG. As shown in FIG. 4B, the shutter link mechanism 46 is pivotally supported by a tongue piece 64 fixed on the bottom plate of the frame 22 via a rotary shaft 65 so that the central portion thereof can swing freely. Both ends are pivoted to the swing rod 66, the cam follower 62 attached to one end of the swing rod 66 and contacting the outer periphery of the shutter cam 48, and the other end of the swing rod 66 and the pin 67 on the arm 45b. A direction in which the attached link member 68 and the cam follower 62 are brought into contact with the outer periphery of the shutter cam 48, that is, a swinging force of the swinging rod 66 in the clockwise direction in FIG. It is comprised by the spring 69 for.
4A and 4B, the contact state between the cam follower 62 and the shutter cam 48 is changed by the rotation of the shutter cam 48, and the cam follower 62 resists the urging force of the spring 69 and the outer periphery of the shutter cam 48 in FIG. When the swing rod 66 is lifted upward and swings counterclockwise in FIG. 4B, the pin 67 attached to the right side in FIG. 4B swings from the swing center of the arm 45b. The shutter 45 is pulled downward via a link member 68 pivotally attached to the other end of the collar 66, and the shutter 45 swings clockwise in FIG.
On the other hand, the contact state between the cam follower 62 and the shutter cam 48 is changed by the rotation of the shutter cam 48, and the cam follower 62 is pushed downward in FIG. When the swinging rod 66 swings in the clockwise direction in FIG. 4B, the pin 67 attached to the right side in FIG. 4B with respect to the swing center of the arm 45b is at the other end of the swinging rod 66. When the shutter 45 is pushed upward via the pivoted link member 68 and the shutter 45 swings counterclockwise in FIG. 4B, it returns to the initial position shown in FIG. The slit 15 is closed.
The separation distance between the rotation shaft 65 of the swing rod 66 and the pin 67 on the arm 45b is changed by the swing of the arm 45b. This change in the separate distance is pivoted at the other end of the pin 67 and the swing rod 66. It is absorbed by the change in posture of the worn link member 68.

  Further, in this embodiment, the inserter motor 34 that functions as a drive source for operating the swing drive means 35 of the elevating plate 33 also functions as a drive source for operating the swing drive means 47 of the shutter 45.

As described above, the rotation of the inserter motor 34 that functions as a drive source of the swing drive means 47 that drives the shutter 45 is transmitted to the cam shaft 38 shown in FIG. 3 via a gear train (not shown).
When the shutter cam 48 fixed to the cam shaft 38 rotates, as described above, the posture of the shutter link mechanism 46 changes due to the change in the contact state between the cam follower 62 and the shutter cam 48 as the shutter cam 48 rotates. The posture change is transmitted to the arm 45b engaged with the shutter link mechanism 46, and the shutter 45 swings, and the plate-like body 45a portion of the shutter 45 closes the slit 15 as shown in FIG. 2 is retracted to a position for opening the slit 15 as shown in FIG. 2, or moved from the slit opening position in FIG. 2 to the slit closing position in FIG.

  In parallel with this operation, the cam 39 fixed to the cam shaft 38 also rotates. When the contact state of the cam follower 43 with respect to the cam 39 changes due to the rotation of the cam 39, the link 42 swings, and this change in posture is transmitted to the link 40 via the link 41 and fixed to the link 40 in FIG. The shaft 36 rotates.

When the shaft 36 rotates in the clockwise direction in FIG. 5, the elevating plate 33 fixed to the shaft 36 swings in the clockwise direction, and the sliding contact portion 33a of the elevating plate 33 descends. As a result, the carrier A swinging member 30 pivotally supported by a shaft 29 fixed in 16 swings counterclockwise in FIG. 5 according to the urging force of the spring 31 and is pivotally attached to one end of the swinging member 30. The head 13 starts to rise.
At this time, the shutter 45 has already been retracted from the slit closed position in FIG. 5 to the slit open position in FIG. 2, and the magnetic head 13 moves up beyond the slit 15.

The tip of the raised magnetic head 13 comes into contact with the magnetic stripe 101 of the passbook 100 sandwiched between the guide plate 5 and the upper plate 7, but in this state, the spring 31 has a certain amount of stored energy. The tip of the magnetic head 13 is reliably pressed against the magnetic stripe 101 by the stored energy of the spring 31.
That is, in this embodiment, the spring 31 constituting the main part of the urging means 27 functions as an urging means for urging the magnetic head 13 in the upward direction while protruding from the slit 15. .

On the contrary, when the shaft 36 rotates counterclockwise in FIG. 5, the elevating plate 33 fixed to the shaft 36 swings counterclockwise and the sliding contact portion of the elevating plate 33 is moved. 33a rises and forcibly pushes up the bearing 32 of the swing member 30.
As a result, the swing member 30 supported by the shaft 29 fixed in the carrier 16 swings clockwise in FIG. 5 against the urging force of the spring 31, and one end portion of the swing member 30. The magnetic head 13 pivotally attached to the head moves downward and returns to the retracted position as shown in FIG.
At this time, the portion of the plate-like body 45a in the shutter 45 moves from the slit open position as shown in FIG. 2 to the slit closed position as shown in FIG.
The state shown in FIG. 5 is the initial position of the magnetic head 13 and the shutter 45.

In other words, the relationship between the swing drive means 35 for swinging the lift plate 33 to move the magnetic head 13 up and down and the swing drive means 47 for swinging the shutter 45 is attached to the common cam shaft 38. By adjusting the shapes of the cams 39 and the shutter cams 48, the long plate-like body 45a in the shutter 45 is removed from the magnetic head 13 while the magnetic head 13 is retracted downward from the slit 15 as shown in FIG. The space between the front end and the slit 15, that is, the slit closed position is held, and when the magnetic head 13 protrudes from the slit 15, the long plate-like body 45 a in the shutter 45 is in the slit release position as shown in FIG. To move to.
Specifically, as shown in FIG. 4B, the cam follower 43 is in contact with the large diameter portion of the cam 39 and the magnetic head 13 is returned to the lower retracted position as shown in FIG. The mounting angle of the cam 39 and the shutter cam 48 with respect to the cam shaft 38 is determined so that the cam follower 62 contacts the small diameter portion of the shutter cam 48 and the shutter 45 returns to the closed position, and the magnetic head 13 starts to rise. The outer peripheral shapes of the cam 39 and the shutter cam 48 are designed so that the shutter 45 is closed after the retraction of the shutter 45 to the slit opening position is completed at the time and the movement of the magnetic head 13 to the retraction position is completed. ing.

Next, the configuration of the carrier 16 corresponding to the vertical bankbook 100 will be described with reference to FIG.
6A is a cross-sectional view showing an example of the configuration of the carrier 16 corresponding to the vertical bankbook 100, FIG. 6B is a plan view thereof, and FIG. 3), only the configuration of the parallel link mechanism for moving the magnetic head 13 up and down is taken out and shown by the direction of the left side view with reference to FIG.

  In the case of the carrier 16 corresponding to the vertical bankbook 100, the biasing means 27 for raising the magnetic head 13 is provided between the carrier 16 and the magnetic head 13, as shown in FIG. The parallel link mechanism 49 and the spring 50 that changes the posture of the parallel link mechanism 49 in the direction in which the magnetic head 13 is raised.

  In the case of the carrier 16 corresponding to the vertical bankbook 100, the forced return means 28 for lowering the magnetic head 13 is fixed in the carrier 16 so as to be parallel to the guide rods 18 and 19. A swinging member 30 whose central portion is rotatably supported by a shaft 29 and whose one end portion is in sliding contact with the upper surface 49a of the parallel link mechanism 49, and a frame so as to be parallel to the guide rods 18 and 19. 22 and at least the elevating plate 33 capable of moving up and down the sliding contact portion 33a slidably contacting the bearing 32 provided at the other end of the swing member 30, and the sliding contact portion 33a of the elevating plate 33 up and down. Lift plate driving means 37 (see FIG. 3) for moving, an inserter motor 34 (see FIG. 2) functioning as the drive source, and the rotation of the inserter motor 34. The constituted by repetitive converted into oscillating motion by rocking unit for transmitting to the elevating plate 33 35 (see Figure 4 (a)).

  Similarly to the above, the swing member 30 does not interfere with the spring 31 in the counterclockwise direction in FIG. 6A around the shaft 29, that is, the posture change of the parallel link mechanism 49 that tries to raise the magnetic head 13. It is urged to rotate in the direction. Further, a bearing 51 for reducing friction is attached to one end of the swinging member 30 that contacts the upper surface 49a of the parallel link mechanism 49 as shown in FIG. 6B.

Specifically, as shown in FIGS. 6 (b) and 6 (c), the parallel link mechanism 49 has one end portion on both the left and right sides of the magnetic head 13 with reference to the directionality of FIG. 6 (b). Inner link members 70, 70 pivotably pivoted, a connecting portion 71 for integrally joining the inner link members 70, 70, and one end pivotally coupled to the other end portions of the inner link members 70, 70 Outer link members 72, 72 and a connecting portion 75 that integrally joins the outer link members 72, 72.
As shown in FIG. 6C, the inner link members 70 and 70 and the outer link members 72 and 72 are pivotally attached via a shaft 73, and the other end portions of the outer link members 72 and 72 are interposed via a shaft 74. And pivotally attached to the base of the carriage 16.
The above-described spring 50 is loosely fitted to the shaft 73, and the inner link member 70 and the outer link member 72 are separated from each other about the shaft 73 by straight portions formed at both ends of the spring 50. The parallel link mechanism 49 is biased in the direction, that is, the direction in which the magnetic head 13 is moved upward with reference to the shaft 74 fixed to the carriage 16.

In the above configuration, when the sliding contact portion 33 a of the elevating plate 33 is lowered, the swing member 30 pivotally supported by the shaft 29 fixed in the carrier 16 is shown in FIG. 6A according to the urging force of the spring 31. The bearing 51 pivoted counterclockwise and pivotally attached to one end of the rocking member 30 is lifted. As a result, the parallel link mechanism 49 changes its posture according to the urging force of the spring 50, and the magnetic head 13 is moved. Raise.
At this time, the shutter 45 has already retracted from the slit closed position in FIG. 6A to the slit open position in FIG. 2, and the magnetic head 13 moves up beyond the slit 15.

The tip of the raised magnetic head 13 comes into contact with the magnetic stripe 101 of the passbook 100 sandwiched between the guide plate 5 and the upper plate 7, but in this state, the spring 50 has a certain amount of stored energy. As a result, the tip of the magnetic head 13 is pressed against the magnetic stripe 101 by the stored force of the spring 50.
That is, in this example, the spring 50 constituting the main part of the urging means 27 functions as an accumulating means for urging the magnetic head 13 in the upward direction while protruding from the slit 15.

On the contrary, when the sliding contact portion 33a of the elevating plate 33 rises, the bearing 32 of the swinging member 30 supported by the shaft 29 fixed in the carrier 16 is lifted by the sliding contact portion 33a. The swing member 30 swings clockwise in FIG. 6A against the urging force of the spring 31, and a bearing 51 pivotally attached to one end of the swing member 30 is connected to the inner link members 70, 70. The upper surface 49a of the communication part 71 is pressed.
As a result, the posture of the parallel link mechanism 49 changes in the direction in which the magnetic head 13 is lowered against the urging force of the spring 50, and the magnetic head 13 returns to the initial position shown in FIG.
At this time, the portion of the plate-like body 45a in the shutter 45 moves from the slit open position as shown in FIG. 2 to the slit closed position as shown in FIG. 6 (a).

  That is, the vertical type carrier 16 shown in FIG. 6 is a spring that functions as a means for returning the oscillating member 30 to the original position of the parallel link mechanism 49 and the spring 50 that constitute the main part of the biasing means 27. 31 (there is no function of urging the magnetic head 13 in the upward direction), the swing member 30 functioning as a means for regulating the operation of the parallel link mechanism 49, and a bearing for pressing the parallel link mechanism 49 Except for the structure 51, the basic structure is the same as that of the lateral type carrier 16 shown in FIG. 5, and the lift plate 33, the lift plate drive means 37, the inserter motor 34, the swing drive means 35, The shutter 45 and the like are exactly the same as those shown in FIGS. 1 to 5 including their functions.

  Therefore, it is possible to attach the carrier 16 corresponding to the vertical bankbook 100 shown in FIG. 6 in place of the carrier 16 (horizontal type) of the magnetic recording / reproducing apparatus 2 shown in FIG. is there.

  That is, the magnetic recording / reproducing apparatus 2 with the carrier 16 shown in FIG. 6 becomes the magnetic recording / reproducing apparatus 2 corresponding to the vertical bankbook 100, and the magnetic recording / reproducing apparatus 2 with the carrier 16 shown in FIG. Thus, the magnetic recording / reproducing apparatus 2 corresponding to the lateral bankbook 100 is obtained.

In this way, the peripheral structure of the carrier 16 that constitutes the main part of the magnetic recording / reproducing apparatus 2 is made common to the vertical type and the horizontal type, and the required parts have unity, so that the vertical type The mass production cost of the magnetic recording / reproducing apparatus 2 and the slip printer 1 corresponding to the passbook 100 and the magnetic recording / reproducing apparatus 2 and the slip printer 1 corresponding to the horizontal passbook 100 can be reduced.
In addition, when the magnetic head 13 is attached with being shifted by 90 ° with respect to the carrier 16 shown in FIG. 6A, there is a problem that the lateral width of the carrier 16 (the height in the vertical direction in FIG. 6B) slightly increases. However, this can be used as the horizontal carrier 16 and if the magnetic head 13 is attached to the carrier 16 shown in FIG. can do.

  Next, the configuration of the control unit 53 provided in the slip printer 1 will be briefly described. As shown in FIG. 7, the main part of the control unit 53 includes a CPU 54 as calculation means, a ROM 55 that stores a control program for the CPU 54, and a RAM 56 that is used for temporary storage of calculation data.

  The carrier drive motor 26, the inserter motor 34, the print head 10, the magnetic head 13, and the carriage drive motor 57 and the carry motor 58, which are not shown in other drawings, are fed by the CPU 54 via an input / output circuit 59 and respective drivers. Detection signals from the side edge detection sensor 12 and the paper insertion sensor 60 and the conveyance position detection sensor 61, which are not shown in other drawings, are read into the CPU 54 via the input / output circuit 59. It is like that. Further, a detection signal from a carrier sensor 52 (see FIG. 4A) fixed on the frame 22 side in order to detect the return of the home position of the carrier 16 moving along the guide rods 18 and 19 is also input / output. The data is read into the CPU 54 via the circuit 59.

The paper insertion sensor 60 is a sensor for detecting insertion of the bankbook 100 into the paper insertion slot 63, and the conveyance position detection sensor 61 is in a paper conveyance path formed between the guide plate 5 and the upper plate 7. It is a sensor for detecting the front-end | tip of the passbook 100 which moves and controlling conveyance operation | movement.
The transport position detection sensor 61 is located at an arbitrary position downstream of the position where mechanical feed to the passbook 100 is started in the paper transport path, that is, on the right side (downstream side) of the drive roller 8 positioned on the left side in FIG. Is provided.

  In addition, the ROM 55 functioning as a storage means corresponds to a separation distance (hereinafter referred to as an offset value) from the end position of the passbook 100 to the attachment position of the magnetic stripe 101 according to the type (issuer, etc.) of the passbook 100. Assume that the stored lookup table is registered in advance. The separation distance here is, for example, a value such as 10.3 mm, 15.7 mm, 40 mm, and 100 mm shown in FIGS. 13 (c) to 13 (f).

  Next, the overall operation of the slip printer 1 provided with the magnetic recording / reproducing apparatus 2 will be described with reference to the flowcharts of FIGS. However, it is assumed that the positions of the magnetic head 13 and the shutter 45 in the initial state are as shown in FIG. 5 in the case of the horizontal type and in FIG. 6A in the case of the vertical type.

  When the user inserts the passbook 100 of the slip printer 1, first, the paper insertion sensor 60 detects the leading edge of the paper and outputs an insertion detection signal to the CPU 54 (step S1).

  Then, the CPU 54 detecting this insertion detection signal drives and controls the carry motor 58, rotates the drive roller 8, and starts carrying the bankbook 100 (step S2). The conveyance direction of the bankbook 100 is a direction from left to right in FIG.

  At this stage, the magnetic head 13 is retracted below the slit 15, the shutter 45 is in the slit closed position shown in FIG. 5 or 6 (a), and the plate-like body 45 a having a partially arcuate cross section is shown in FIG. 3. As shown, since the slit 15 is closed on the same plane as the guide plate 5 by entering the slit 15, there is no fear that the tip of the bankbook 100 is caught on the edge of the slit 15, the shutter 15, or the like.

  Normally, when inserting the bankbook 100, it is necessary to position the side end against the side plate 6; however, in the present embodiment, the side end of the bankbook 100 needs to be accurately positioned on the side plate 6. No, it is only necessary that the side end portion of the bankbook 100 is parallel to the side plate 6.

  Then, the conveyance of the bankbook 100 proceeds by the rotation of the driving roller 8, and when the leading end of the bankbook 100 is detected by the conveyance position detection sensor 61, a leading edge detection signal is output from the conveyance position detection sensor 61 to the CPU 54 (step S3). ).

The CPU 54 that has detected the leading edge detection signal starts counting drive command pulses output to the transport motor 58 (step S4), and when the count value reaches a set value (step S5), the transport is performed. The driving of the motor 58 is stopped and the feeding of the bankbook 100 is stopped (step S6).
In the case of the horizontal passbook 100 as shown in FIGS. 13A to 13B, there may be some difference in the distance from the insertion end of the passbook 100 to the center position of the magnetic stripe 101. The setting value corresponding to the type of the passbook 100 is stored in the ROM 55 in advance, the setting value corresponding to the type of the passbook 100 is read, the setting value is compared with the count value, and the conveyance motor 58 is stopped. Although it is necessary to position the center of the magnetic stripe 101 at the position of the slit 15 on the guide plate 5, in the case of the vertical bankbook 100 shown in FIGS. 13 (c) to 13 (f), the bankbook 100 is inserted. Since the distance from the end to the tip position of the magnetic stripe 101 is common, this set value may be a fixed value.

  In this way, the feeding of the passbook 100 is stopped, and the center of the magnetic stripe 101 in the width direction (in the case of the horizontal type) or the tip portion (in the case of the vertical type) is positioned at the position of the slit 15 on the guide plate 5. Thereafter, the CPU 54 drives the carriage drive motor 57 while counting the number of drive command pulses output to the carriage drive motor 57, and starts the carriage 11 of the print head 10 in the direction orthogonal to the paper transport direction from the home position. It is moved (step S7), and the presence or absence of the input of the end detection signal from the side end detection sensor 12 provided in the print head 10 is watched.

  When the side edge detection sensor 12 that moves integrally with the carriage 11 detects the side edge of the bankbook 100, an edge detection signal is output from the side edge detection sensor 12 to the CPU 54 (step S8).

  The CPU 54 that has detected the input of the edge detection signal, based on the count value of the drive command pulse at this time, the distance from the home position of the carriage 11 to the side edge of the bankbook 100, that is, the side plate 6 to the bankbook 100. After obtaining and temporarily storing the distance to the side end (hereinafter referred to as the amount of positional deviation) (step S9), the carriage drive motor 57 is driven in reverse to return the carriage 11 of the print head 10 to the home position (step S9). S10).

Next, the CPU 54 searches the lookup table in the ROM 55 to obtain an offset value corresponding to the type of the bankbook 100 inserted at the present time (step S11), and adds this offset value to the above-described positional deviation amount. The movement target position in the direction perpendicular to the paper conveyance path where the magnetic head 13 is to be positioned is obtained with the home position of the magnetic head 13 as the coordinate origin. However, the value actually obtained is the number of drive command pulses required to move the magnetic head 13 from the home position (coordinate origin) to the movement target position (step S12).
In order to determine the type of the bankbook 100, another device such as a barcode reader may be provided.

  Next, the CPU 54 controls the drive of the carrier drive motor 26 while counting the number of drive command pulses output to the carrier drive motor 26, operates the drive pulley 23 and the timing belt 25 constituting the feeding means 20, and descends. While the carrier 16 holding the magnetic head 13 in the state is fed in the direction perpendicular to the sheet conveyance path (step S13), the system waits for the count value to reach the number of pulses corresponding to the movement target position.

  Since the carrier 16 is moved while the magnetic head 13 is lowered, the tip of the magnetic head 13 is not caught by the bankbook 100 or the magnetic stripe 101. No worries about change.

  When the carrier 16 is fed, the carrier 16 moves while the swing member 30 on the carrier 16 side is in sliding contact with the lift plate 33 on the frame 22 side. The swing member 30 is lifted and lowered via the bearing 32. Since it is in contact with the sliding contact portion 33a of the plate 33, an excessive sliding contact resistance does not act.

  Then, this count value reaches a value corresponding to the movement target position, and the magnetic head 13 is directly below the front end of the magnetic stripe 101 in the passbook 100 (in the case of the horizontal type) or directly below the center in the width direction (of the vertical type). When it is confirmed that the carrier drive motor 26 has been reached (step S14), the CPU 54 stops the operation of the carrier drive motor 26 and stops the feeding of the carrier 16 (step S15).

  Since the movement amount of the carrier 16 is calculated based on an offset value and a positional deviation amount unique to the bankbook 100, it is possible to deal with various types of bankbooks 100 having different magnetic stripe 101 attachment positions. Similarly, it is possible to deal with variations in the position of the magnetic stripe 101 caused by a positional shift when the bankbook 100 is inserted.

  Next, the CPU 54 operates the inserter motor 34 that functions as the drive source of the swing drive means 35 in the elevating plate 33 and the drive source of the swing drive means 47 in the shutter 45, so that the shutter 45 is operated as shown in FIG. 2 is retracted from the slit closing position shown in FIG. 2 to the slit opening position shown in FIG. 2 and the magnetic head 13 is raised and brought into contact with the magnetic stripe 101 of the pad 100 (step S16).

  As described above, even when the raising of the magnetic head 13 is completed, the spring 31 (in the case of the carrier 16 in FIG. 5) or the spring 50 (in the case of the carrier 16 in FIG. 6) functioning as a storing means Since the energy storage state is maintained, the tip of the magnetic head 13 can be reliably pressed against the magnetic stripe 101.

  Further, the carrier 16 is positioned at various positions on the guide rods 18 and 19 depending on the specifications of the bankbook 100, the amount of positional deviation at the time of insertion, and the like, but the lifting plate that drives the magnetic head 13 in the vertical direction. Since 33 is arranged so as to be parallel to these guide rods 18 and 19, the magnetic head 13 can be lifted and lowered reliably by the swinging motion of the lifting plate 33 regardless of the positioning position of the carrier 16. Can be made.

Next, the CPU 54 determines whether the horizontal carrier 16 or the vertical carrier 16 is mounted on the slip printer 1 (step S17).
Specifically, for example, the slip printer 1 is provided with a dip switch or the like, and a value corresponding to the type of the attached carrier 16 is manually set at the time of factory shipment, and the value of the dip switch or the like is read in the process of step S17. The determination process may be performed at.

  Here, when it is determined that the slip printer 1 is of the lateral direction type, the CPU 54 drives and controls the carrier drive motor 26 to operate the drive pulley 23 and the timing belt 25 constituting the feeding means 20. The carrier 16 is fed in a direction orthogonal to the paper transport direction while the tip of the magnetic head 13 is in contact with the magnetic stripe 101, and the magnetic head 13 is driven to read magnetic information from the magnetic stripe 101, or Write (step S18).

  Since the tip of the magnetic head 13 is reliably pressed against the magnetic stripe 101, reading and writing of magnetic information can be performed accurately.

  When reading and writing of magnetic information is completed in this way, the CPU 54 reverses the inserter motor 34 that functions as the drive source of the swing drive means 35 in the lifting plate 33 and the drive source of the swing drive means 47 in the shutter 45 in the reverse direction. And the magnetic head 13 is lowered to retract its tip portion below the slit 15 and the shutter 45 is moved from the slit open position shown in FIG. 2 to the slit shown in FIG. 5 or FIG. Return to the closed position (step S25).

  Then, the CPU 54 drives and controls the conveyance motor 58 in the reverse direction until the paper insertion sensor 60 no longer detects the passbook 100, and reverses the drive roller 8 to move the passbook 100 in the direction from right to left in FIG. After the sheet is discharged to the sheet insertion port 63 (steps S26 to S27), the operation of the transport motor 58 is stopped (step S28).

  At the ejection stage, the magnetic head 13 is retracted below the slit 15, the shutter 45 is in the slit closed position shown in FIG. 5 or 6 (a), and the portion of the plate-like body 45 a having a partial arc-shaped cross section is As shown in FIG. 3, the slit 15 is substantially blocked on the same plane as the guide plate 5 so as to enter the slit 15, so that the bankbook 100 may be caught on the edge of the slit 15, the shutter 15, or the like. There is no.

  Next, the CPU 54 drives and controls the carrier drive motor 26 to actuate the drive pulley 23 and the timing belt 25 constituting the feeding means 20, and return the carrier 16 holding the magnetic head 13 in the lowered state to the home position. When the input of the detection signal from the carrier sensor 52 is confirmed, the operation of the carrier drive motor 26 is stopped, and each part of the slip printer 1 is returned to the complete initial state (step S29).

  In this way, without waiting for the home position of the magnetic head 13 to return, immediately after reading and writing of magnetic information, the magnetic head 13 is lowered, the shutter 45 is closed, and the return of the bankbook 100 is started (step S18, step S18). The time required for the overall passbook process can be shortened (see S25 to step S26).

  On the other hand, if it is determined by the determination process in step S17 that the slip printer 1 is of the vertical direction type, the CPU 54 initializes the value of the retry counter C to 0 (step S19), and then carries it. The motor 58 is driven and controlled, and the driving roller 8 is rotated to move the bankbook 100 in the paper conveyance direction, so that the magnetic stripe 101 is made relative to the magnetic head 13 while the tip of the magnetic head 13 is in contact with the magnetic stripe 101. Then, the magnetic head 13 is driven and controlled to read or write magnetic information from the magnetic stripe 101 (step S20).

  Next, the CPU 54 determines whether or not an error has occurred during reading and writing of magnetic information (step S21). If there is no error, the CPU 54 executes the processing from step S25 to step S29 in the same manner as described above to transfer the bankbook 100 to the user. Return to

  If the occurrence of an error is detected in the determination process in step S21, the CPU 54 further determines whether or not the current value of the retry counter C has reached the retry allowable number N (set value) (step S21). S22).

  If the current value of the retry counter C has not reached the allowable number of retries N, the CPU 54 drives and controls the transport motor 58 and reverses the drive roller 8 so that the bankbook 100 is printed by the length corresponding to the length of the magnetic stripe 101. The feed pulley 20 and the timing belt 25 are operated by driving the carrier drive motor 26 to control the carrier drive motor 26, and the carrier 16 is orthogonal to the paper feed direction. The magnetic head 13 is moved to a position slightly offset from the center in the width direction of the magnetic stripe 101 to increment the value of the retry counter C by 1 (step S24). Feeding the bankbook 100 with the tip of the head 13 in contact with the magnetic stripe 101 More magnetic stripe 101 is relatively moved with respect to the magnetic head 13 reads the magnetic information from the magnetic stripe 101 drives and controls the magnetic head 13, or attempts to write (step S20).

  This retry process can be repeated up to N times. During this time, if it is detected in the determination process in step S21 that the magnetic information has been properly read and written, the same process as described above is performed. The process of step S25-step S29 is performed and the passbook 100 is returned to a user.

In addition, when the read / write is not performed properly even after repeating the retry process N times, and the value of the retry counter C reaches the retry allowable number N, the CPU 54 has serious damage to the magnetic stripe 101. Thus, the retry process is stopped, and the process of steps S25 to S29 is executed in the same manner as described above to return the bankbook 100 to the user.
In the case of the slip printer 1 used in a bank or the like, it is desirable to display an alert message notifying that the magnetic stripe 101 is damaged.

  As described above, in the longitudinal-type slip printer 1, the magnetic stripe 101 is demagnetized by repeating the processes related to reading and writing of magnetic information with the magnetic head 13 slightly shifted from the center in the width direction of the magnetic stripe 101. Even when there is a problem such as (demagnetization), it may be possible to read and write magnetic information, and the trouble of reissuing the passbook 100 and the running cost can be reduced.

  Note that the amount of offset movement of the magnetic head 13 for one time in step S24 is appropriately determined according to the width of the magnetic stripe 101, the size of the magnetic head 13, and the like.

  Further, in the case of the horizontal type voucher printer 1, when an error occurs in reading / writing magnetic information, the magnetic head 13 is temporarily returned to the home position, and the driving roller 8 is actuated to feed the bankbook 100. It is also conceivable that after the magnetic head 13 is slightly shifted from the center in the width direction of the magnetic stripe 101, the retry process is performed by moving the magnetic head 13 in the direction perpendicular to the transport path.

  In addition to the above processing operations, actually, the drive control of the print head 10 for printing various transaction information on the bankbook 100, and the drive control of the carriage drive motor 57 and the carry motor 58 required at that time. However, since these points are publicly known, description thereof is omitted.
