"Prior Art" In such a copying apparatus, generally only an image of an original document is copied onto copy paper.

By the way, it is necessary to write additional information that is not present in the original manuscript image, such as textual information about the image, such as the date, name, size, number of pages, user/department, etc., on the copy paper along with the copied image. occurs frequently.

In such cases, conventionally, the first step has been to hand-write the relevant character information on the copy paper on which the image has already been copied by the copying device. Also second
First, the text information written on the image of the manuscript is written by hand with a pencil or the like, and then the copying device is used to copy the text information along with the image onto the copy paper. Information was also erased.

"Problems to be Solved by the Invention" By the way, the following problems have been pointed out in such conventional examples.

First of all, the above-mentioned conventional handwriting method is time-consuming and troublesome, and especially when there are a large number of copies, the text information must be handwritten one by one, resulting in a problem of very low office efficiency. . Furthermore, the method of writing on the original in Conventional Example 2 is also time-consuming and troublesome, and the text information on the copy paper may become unclear or unclear.Furthermore, in the case of a reader printer, etc. It is difficult to write such character information to a computer, and it has become impossible to use such a method.

In the conventional example, the above points were pointed out.

31 The present invention has been made in view of the above-mentioned circumstances and to solve the problems of the conventional example, and is made by providing a slit with a liquid crystal panel for displaying character information regarding the image. An object of the present invention is to propose a copying device in which character information can be simply, easily and reliably printed together with an image.

"Means for Solving the Problems" The technical means of the present invention to achieve this objective are as follows.

This copying device scans and moves the original and an optical system relative to each other, projects the image of the original illuminated by light from a light source onto a photoreceptor through a slit, and copies it onto copy paper. be. It also includes the following input means, print position designation means, liquid crystal panel, and the like.

The input means is for inputting character information regarding the image.

The print position specifying means specifies the print position of this character information with respect to the image.

The liquid crystal panel is provided with a slit, and the light transmittance changes from light-transmitting to light-blocking, and the character information is displayed in synchronization with the scanning movement of the projected image based on signals from the input means and the printing position designation means. This is what is displayed.

The character information displayed on the liquid crystal panel is then formed as a corresponding electrostatic latent image on the charged photoreceptor.
Printed on copy paper by developing and copying.

"Function" Since the copying apparatus according to the present invention is comprised of such means, it functions as follows.

First, character information necessary for the image is input by the input means. Further, the print position specifying means specifies the print position of the text information with respect to the image at an appropriate location in the margin area 1 image around the image.

Then, in synchronization with the scanning movement of the projected image in the slit, the character information is displayed on the liquid crystal panel provided in the slit based on signals from the input means and the print position designation means.

Therefore, on the charged photoreceptor, the character information shown in Table 5 is projected and exposed together with the image to form a corresponding electrostatic latent image. After this electrostatic latent image is developed, it is transferred to the fed copy paper.

In this way, the copied image and its text information are simply, easily and reliably printed on the copy paper.

"Example" The present invention will be described in detail below based on the example shown in the drawings.

First, the configuration etc. will be explained in the following order: the outline of the reader printer, the recording card, etc., the operation panel, the print position designating means 2 image designating means, the liquid crystal panel, etc.

An overview of a reader printer, which is an example of a copying device, is as follows.

FIG. 11 is a perspective view of its appearance, and FIG. 12 is a perspective view of its optical system.

Light from a light source 1 such as an exposure lamp is focused by a movable condenser lens 2 and a fixed condenser lens 3,
It passes through the microfilm 4, which is the manuscript, by irradiating it from below,
The projection lens 5 is reached. As a result, the image P on the microfilm 4 is enlarged and projected by the projection lens 5.

In the reader mode, the image P projected from the projection lens 5 is transmitted to the reader first mirror 6 at the reader position.
The image is then bent by a fixed leader second mirror 7 and is enlarged and projected onto a screen 8 placed at the upper front of the main body. During this time, the first print mirror 9 moves to the retracted position on the right side of the figure and assumes a folding posture, and the third print mirror 10 also moves to the retracted position at the front in the figure, retracting out of the leader optical path formed together. ing.

Next, in the print mode, first the reader first mirror 6 moves upward from the reader position and retreats out of the formed printer optical path. Print on behalf of the first mirror 9
The print third mirror 10 synchronizes with the above-mentioned retracted position and moves in reverse scanning to the left and rear scan start positions in the figure, respectively, and then moves from the respective scan start positions toward the right and front scan end positions. Scan and move. In this way, the image P from the projection lens 5 is transferred to the print first mirror 9
．． Fixed printed second mirror 11. Printed third mirror 10. The printed image is bent by a fixed fourth mirror 12 and projected onto the surface of a rotating drum-shaped photoreceptor 13 through a slit to be described later. Then, an image is formed by a known process and copied onto copy paper 14. That is, the image P is projected onto the charged photoreceptor 13 by slit projection exposure to form an electrostatic latent image, toner is attracted to this electrostatic latent image to develop it, and the image is fed from a paper feeder (not shown). The image is copied by transferring it to the printed copy paper 14.

In the illustrated example, the first print mirror 9 and the third print mirror
A method is used in which the mirror 10 scans and moves, that is, the optical system moves in a scanning manner.However, as is adopted in some electronic copying machines, on the contrary, the optical system is all fixed and the document is scanned. Of course, it is also possible to consider a method in which both sides move in a scanning manner.

In FIG. 1F, 15 is a roll film carrier into which the microfilm 4 is loaded, 16 is a paper feed cassette for the copy paper 14, and 17 is a paper discharge tray after copying. Further, in FIG. 12, 18 is a first reflecting mirror arranged behind the light source 1, and 19 is a second reflecting mirror that bends the light upward.

The reader printer looks like this.

Next, the recording card etc. will be explained.

This reader printer, which is a copying device, is managed by a system using a recording card. This record card records management information regarding the usage status of the reader printer, such as the total number of copies made, number of copies per size per date, user/department, number of service calls, copying fee, etc. In addition to the method of recording various items of management information, it is of course possible to perform this recording of only one type of item, such as the total number of copies.

A typical example of this recording card is a magnetic card 20 that records magnetically.
IC cards that record on AM and various other recording methods are conceivable. Reference numeral 21 in FIG. 11 is a card reading means 21 connected to the reader/printer. This card reading means 21 reads, for example, a loaded magnetic card 2.
Management information is read from 0 using a magnetic head.

The recording cards etc. are like this.

Next, the operation panel 22 will be explained.

FIG. 4 is a front view thereof.

-10= The operating panel 22 thus primarily forms such a general operating means of the reader-printer.

The operation panel 22 also forms a second means for inputting character information regarding the image P.

That is, this operation panel 22 further includes a print set key 3.
2 and a print display section 33 such as a liquid crystal type, a signal corresponding to the press of the print set key 32 is sent to the microcomputer 31, and a display signal is sent from the microcomputer 31 to the print display section 33 via a drive circuit 34. is output. Note that the textual information regarding the image P is additional information that is not present in the image P on the microfilm 4 that is the original manuscript, that is, information that is not projected on the screen 8.
Date 1 name, size, number of pages of image P.

Refers to users, departments, etc. Also, symbols other than pure letters.

It is also possible to use figures etc. as a medium.

By pressing the print set key 32, the lamp key 28 is first pressed.
The code is shifted from the key for turning on the light source 1 and extinguishing smoke to the key representing a slash, that is, "/", and a display signal is output to the print display section 33. For example, by using the numeric keypad 27 and lamp key 28, r87/3/2
When 0J is pressed, the date will be displayed on the print display section 33. The clear key 29 is used normally (for erasing and redoing).

Note that the means for inputting character information regarding the image P is not limited to using the operation panel 22 of the main body of the reader printer, etc., but may also use, for example, a connected Mars controller, a personal computer, or the like. That is, for example, a Mars controller, which is an accessory device for automatic image search of the reader printer, may be used, and character information regarding the image P may be input using its operation panel in the same manner as described above. In this case, the nth
When copying from frame to nth frame plus m frame, 1/
It is possible to print the number of pages from m+1 to m+1/m+1, and it is also possible to provide an automatic page printing function.

Now, thirdly, the operation panel 22 It also forms steps.

That is, management information regarding the usage status of the reader printer, which is a copying device, is read from the magnetic card 20 or the like by the card reading means 21 and sent to the microcomputer 31. Select items and make other additional inputs.

This is done, for example, on the condition that the magnetic card 20 is loaded into the card reading means 21 and the print set key 32 is pressed.
This is done by shifting the code of each key and sending out the corresponding signal.

For example, "1" to "9" on the numeric keypad 27 indicate the total number of copies, which is management information related to usage status.

Number of copies by size 2 This key is used to specify the date, user/department, number of service calls, copying fee, etc. and either numeric keypad 2
By pressing 7, via the microcomputer 31 etc.
The management information corresponding to that number is selected, and the print display section 3

Further, the lamp key 28 is used as a composite key. For example, if you need the total number of copies by department,
After pressing the number key 27 corresponding to the department, the lamp key 28 is pressed, and then the number key 27 corresponding to the total number of copies is pressed. Moreover, "0" on the numeric keypad 27 is not the management information recorded on such a magnetic card 20, but the date, page number, etc. are displayed and printed as manual management information in accordance with the character information regarding the image P mentioned above. Used as a shift key when Regarding the number of copies by size, the number of copies of the selected copy paper 14 is added. That is, the number of copies recorded on the magnetic card 20 up to the previous time plus one copy, in other words, the number of copies including the current copy will be displayed and printed.

Note that, other than the example described above, it is also possible that only one type of management information is recorded on the magnetic card 20, so that there is no need to use the operation panel 22 as a management information instruction means.

The operation panel 22 looks like this.

Next, the print position designation means will be explained.

FIGS. 5 and 6 are front views thereof.

The print position specifying means 35 specifies the print position of the character information regarding the image P inputted through the operation panel 22, which is the input means described above, to an appropriate location in the image P, for example, in the margin area around the image P. be.

Since the printing position specifying means 35 is configured as shown below,
For example, it is used as shown in FIG.

First, if character information regarding the image P input manually using the operation panel 22 serving as an input means is, for example, [87/3/20j], that fact is displayed on the print display section 33. The size and position of the image P on the screen 8 are shown by imaginary lines in the figure.

First, the first X cursor 43 is moved in the X direction to the outside of the key frame 48 using the first X knob 36 .

As a result, the image P is specified to be printed side by side in the Y direction and the vertical direction on the screen 8. Then the second

The positions of the Y knobs 38 and 39 are input to the microcomputer 31 via potentiometers, and a signal for specifying a printing position is output to a liquid crystal panel, which will be described later.

In the figure, 51 is a display section for displaying the number of copies and the size of the copy paper 14, and 52 is a hiding panel.

Firstly, the printing position specifying means 35 is configured to specify the first printing position as shown in the figure. 2nd X knobs 36, 37, 1st. 2nd Y knob 38
．． 39, 1st. 2nd X cursor 43.44, 1st. Second
The method is not limited to the method of specifying the print position using the Y cursor 45, 46, etc., and a method using, for example, an LED is also possible. That is, a large number of LEDs are lined up in the X direction and the Y direction on the screen frame 40, and by shifting the code of each key on the operation panel 22, the lighting location of the LEDs is moved and controlled, and the image P is changed by lighting the desired location. You may also specify the print position for.

Second, the printing position specifying means 35 is not limited to such a variable specifying method, but may also be a fixed specifying method in which a specific position is fixedly specified from the beginning.

Thirdly, this printing position designation means 35 prints the management information regarding the above-mentioned usage state, which is read by the card reading means 21 and selected by the operation panel 22 as management information instruction means, by the printing means described below. Of course, it can also be used for specifying a print position when printing. When the print position designating means 35 is used only for such management information, the cursor and knob may be simplified as shown below, regardless of the illustrated example. For example, a Y cursor and its knob that can be moved in the Y direction, and an
It is also possible to provide a cursor and its knob, with the position of each knob being outputted via a potentiometer.

The print position designating means 35 is as follows -20- Ru.

Next, the image instruction means will be explained.

The image designating means appropriately designates the leading and trailing edges of the projected image P to be copied in the scanning direction and, in the illustrated example, both ends in the image width direction orthogonal thereto.

FIG. 7 is a side view showing an example of the optical sensor 53, etc.;
FIG. 8 is a front sectional view thereof, and FIG. 9 is an explanatory plan view thereof.

54 is a moving table, and this moving table 54
The mirror 9 is held via a holder 55 and guided by a scanning shaft 56 to move it in the scanning direction and in the reverse scanning direction shown by arrows in FIGS. 8 and 9. An optical sensor 53 such as a solid-state imaging device is fixed to the bottom surface of the front end of the moving table 54 in the reverse scanning direction. As shown in FIG. 9, this optical sensor 53 is set to be longer than the size in the image width direction of the largest image P' projected from the projection lens 5. Therefore, by moving the optical sensor 53 in the reverse scanning direction indicated by the arrow, the optical path from the projection lens 5 is sequentially cut, thereby making it possible to photometer the necessary amount of light over the entire surface of the projected image P.

Since the optical sensor 53 is configured as described above, in the case of the so-called negative-positive mode in which a positive image is copied from the microfilm 4 of the original negative image, the projected image P is detected at the leading and trailing ends to be copied in the scanning direction. In the illustrated example, the leading and trailing edges 57 and 57 of the image P itself, and both side edges to be copied in the image width direction orthogonal thereto, and both side edges 58 and 58 of the image P itself in the illustrated example are detected and indicated as follows.

That is, first, the size specifying means 59 (first
0), the size of the copy paper 14 to be fed is selected. When the print key 26 (see FIG. 4) is pressed and the first print mirror 9 moves in reverse scanning to its scanning start position, the optical sensor 53 prints a copy of length 15iW corresponding to the size of the copy paper 14. The amount of light in the paper area 60 is measured. Then, in the image width direction, ranges a and a' where the light amount does not change and are large, ranges b where the light amount changes and is small, and ranges c and c' where the light amount does not change and are large and ranges d where the light amount changes and is small are detected in the scanning direction. That will happen. These ranges a and a' correspond to the margins between the opposite edges 58° 58 of the projected image P and the opposite edges of the copy paper area 60. Similarly, ranges c and c' are
This corresponds to the margin between the leading and trailing edges 57 and 57 of the projected image P and the leading and trailing edges of the copy paper area 60. In this way, the range d extends from the area of the image P, and its both sides 5
8.58 and the leading and trailing ends 57.57 are detected and indicated.

Note that the image indicating means is not limited to the method using such an optical sensor 53, but may also be a manual method using the above-described printing position specifying means 35, or other methods. That is, for example, 1st. 2nd X knob 36.37
and 1st. By operating the second Y knobs 38 and 39, the first.
2nd X cursor 43.44 and 1st. 2nd Y cursor 45
By placing .degree. 46 at each edge of the image P projected onto the screen 8, the front and rear edges 57,57 and both side edges 58,58 are easily indicated.

In the case of partial copying, a manual method using this printing position specifying means 35 is mainly adopted as the image specifying means, and each cursor 43, 44, This is done by placing 45°46.

The image indicating means is like this.

Next, the liquid crystal panel etc. will be explained.

FIG. 1 is a perspective view thereof, and FIGS. 2 and 3 are explanatory views of its operation, respectively.

The drum-shaped photoreceptor 13 is rotated, for example, in the counterclockwise direction as shown by the arrow, and this rotation is caused by the scanning movement of the first printing mirror 9 and the third printing mirror 10, that is, the projected image P is thereby rotated. It is synchronized with the scanning movement. A slit frame 6 is provided near the photoreceptor 13.
1 are located opposite to each other.

This slit frame 61 has a slit 6 formed therein.
A liquid crystal panel 63 is fitted over the entire area of 2.

This liquid crystal panel 63 has a large number of partitioned transparent electrodes arranged in a dense matrix, each of which is addressed, and the light transmittance varies depending on the voltage applied to each transparent electrode. It is designed to change from transparent to blackout. Further, in this liquid crystal panel 63, a downstream end 64 of the image P in the arrow scanning direction is covered with a light shielding plate 65 having an internal space, and is always shielded from light from the optical path. This light shielding plate 6
In the internal space of 5, there is a dedicated light ri, 66 such as a halogen lamp that can uniformly illuminate the downstream end 64 of the liquid crystal panel 63.
is provided.

First of all, as shown in FIG. 2, during scanning movement in the so-called negative/positive mode, the liquid crystal panel 63 displays an image of the projected image P based on a signal from the optical sensor 53, which is an image indicating means. Light transmission is controlled in synchronization with the scanning movement between the leading and trailing ends 57,57 at intervals corresponding to both ends 58,58 in the width direction, that is, in the entire range. The liquid crystal panel 63 is shielded from light except for this light transmission control portion.

That is, at the start of the scanning movement, the entire surface of the liquid crystal panel 63 is initially in a light-shielded state. Based on the signal related to the image P detected by the optical sensor 53, control is performed as shown in FIG. 2 (1), (2), and (3). First, when the front and rear ends 57 of the projected image P pass the upstream edge 67 of the liquid crystal panel 63, the light shielding of the liquid crystal panel 63 is released as the image P is scanned downstream in the scanning direction. Note that the width thereof is an interval corresponding to both side edges 58.58 of the image P. During the scanning movement of the image P, the liquid crystal panel 63 maintains the light-transmitting state, and when the rear end of the front and rear edges 57 of the image P passes the upstream edge 67, the image P is scanned downstream in the scanning direction and Translucency is removed again.

Note that partial copying also follows this method, and only necessary portions of the image P are controlled to transmit light, while unnecessary portions are blocked.

Secondly, as shown in FIG.
Based on the signal from the -26= projected image P, text information regarding the image P is displayed at a predetermined position in synchronization with the scanning movement of the image P.

Thirdly, as shown in FIG. 3, this liquid crystal panel 63 displays management information regarding the usage status of the reader/printer etc. based on the signal from the card reading means 21, and displays the copy fed from the paper feed section. Display to be printed on paper 14.

That is, in this case, the liquid crystal panel 63 forms a printing means for printing management information on the copy paper 14 together with the photoreceptor 13 and the like.

Note that the means for printing such management information is the liquid crystal panel 63. It is not limited to the type using the photoreceptor 13, for example, a type device may be provided in the paper feed section of the copy paper 14, and various other types of devices such as a reader printer etc. that print predetermined management information on the copy paper 14 may be used. This method is possible.

Now, let's move on to the second point mentioned above. The details of the third liquid crystal panel 63 are as follows.

First of all, in PosiPosi mode, it is as follows. That is, in the mode of obtaining a copy of a positive image from the microfilm 4 of a positive image, the liquid crystal panel 63 in the slit 62
When the projected image P scans and moves, the operation panel 22, which is an input means, and the print position designation means 35. Card reading means 21. Control is performed as follows based on signals from the operation panel 22 or the like as management information instruction means. That is, characters 68 representing character information regarding the image P or management information regarding the state of use are displayed as light-shielding portions on the liquid crystal panel 63 at timings corresponding to predetermined positions.

As shown in FIG. 3 (1), (2), and (3), the characters 68 are continuously displayed moving downstream at the same speed as the scanning movement of the image P. . In this way, using the projection optical path of the image P, predetermined character information and management information are projected onto the photoreceptor 13 and printed on the copy paper 14.

Next, the negative/positive mode is as follows.

The light shielding plate 6 of the liquid crystal panel 63 is indicated by the broken line in FIG.
A downstream end portion 64 covered by 5 is always shielded from light, and the rest of the downstream end portion 64 is, in principle, transparent. When projecting and exposing the image P onto the photoreceptor 13, an operation panel 22 serving as an input means is used. Print position designation means 35. Based on signals from the card reading means 21, the operation panel 22 as management information indicating means, etc., the following control is performed. In other words, predetermined character information or characters 68 representing management information are displayed downstream of the liquid crystal panel 63. The end portion 64 is displayed as a transparent portion at a timing corresponding to a predetermined position in synchronization with the circumferential speed of the photoreceptor 13 being rotated, and a dedicated light source 66 is turned on during this time. light rX
66 light, predetermined character information and management information are transferred to the photoreceptor 1.
3 is projected and exposed and printed on copy paper 14.

The liquid crystal panel 63 has this structure.

The above is the explanation of the configuration, etc.

Next, the operation etc. will be explained.

The operator of the reader printer searches for the image P on the microfilm 4, and presses the zoom key 232, image rotation key 24, focus key 25, etc. on the operation panel 22 to perform necessary zooming, image rotation, focusing, etc. , the desired image P is accurately projected onto the screen 8.

Then, when the print key 26 is pressed, the image P
is ready to be copied immediately.

Now, if you want to print character information regarding the image P, the procedure is as follows.

First, necessary character information regarding the image P is input using an input means such as the operation panel 22 or the like.

In other words, in the illustrated example, when the print set key 32 is pressed, the code of a predetermined key is first shifted, and then the numeric keypad 27 . Lamp key 28. By pressing the clear key 29 or the like, character information regarding the image P is input. The text information is displayed on the print display section 33.

Further, the position of such character information with respect to the image P is specified by the print position specifying means 35.

That is, in the illustrated example, the first. 2nd X knob 36°37,
1st. By operating the second Y knobs 38 and 39, the first. 2nd X cursors 43, 44, 1st. 2nd Y cursor 45.
46 is moved in the X direction and the Y direction, so that the screen 8
The position of the text information relative to the image P is specified above. Note that in many cases, this designation is performed in the margin around the image P.

When the print key 26 is then pressed, the above text information is displayed at a predetermined position on the liquid crystal panel 63 provided in the slit 62 in synchronization with the scanning movement of the projected image P, as shown in FIG. will be displayed.

That is, first of all, in the positive-positive mode, the following is true.

In this case, the entire surface of the liquid crystal panel 63 is in a translucent state. And the liquid crystal panel 6 in the slit 62
When the projected image P scans and moves, an operation panel 22.3 serving as an input means is used. Based on the signal from the print position specifying means 35, control is performed as follows. That is, characters 68 representing the above-mentioned character information are displayed as a light-shielding portion on the upstream side of the liquid crystal panel 63 at a timing corresponding to a predetermined position. The characters 68 are continuously moved and displayed on the liquid crystal panel 63 toward the downstream side at the same speed as the scanning movement of the image P.

In this way, predetermined character information is projected onto the photoreceptor 13 using the projection optical path of the image P.

In addition, in the negative/positive mode, the following applies.

In this case, the liquid crystal panel 63 is configured such that a downstream end 64 covered by a light shielding plate 65 is always shielded from light, and other parts than this downstream end 64 are, in principle, transparent.

When projecting and exposing the image P onto the photoreceptor 13, an operation panel 22 serving as an input means. Based on the signal from the print position specifying means 35, control is performed as follows. That is, characters 68 representing the above-mentioned character information are displayed as a transparent portion on the downstream end 64 of the liquid crystal panel 63 at a timing corresponding to a predetermined position in synchronization with the circumferential speed of the photoreceptor 13 being rotated. During this time, the dedicated light source 66 is turned on.

In this way, predetermined character information is projected and exposed onto the photoreceptor 13 using the light from the dedicated light source 66.

Then, such character information is projected and exposed together with the image P onto the charged photoreceptor 13 to form a corresponding electrostatic latent image.

After this electrostatic latent image is developed, it is transferred onto the fed copy paper 14.

In this way, the copied image P and its text information are simply, easily and reliably printed on the copy paper 14.The above is a description of the operation, etc.

"Effects of the Invention" As explained above, the copying apparatus according to the present invention is provided with a liquid crystal panel in the slit for displaying text information regarding the image, so that the text information can be easily, easily and reliably displayed along with the copied image. is printed on. Therefore, it is no longer necessary to write text information on copy paper or manuscripts each time.
It is convenient to save time and improves office efficiency, and it can also be used easily and reliably in the case of manuscripts such as microfilm that are difficult to write on, that is, in reader printers, and the problems that existed in this type of conventional method are avoided. Its effects, such as being wiped out, are remarkable and great.
