Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a copying apparatus that can also copy additional information displayed on a display means when copying document information.

(Prior Art) Proposals for imprinting dates (year, month, day or time) on copies have already been made (for example, Japanese Patent Laid-Open No. 53-3912
No. 4). However, with conventional devices, the operator simply displays the date or input number on the display and copies it, but in order to change the number imprinted on the copy, the operator must input a new number. Ta. For this reason, (A
) When creating the desired number of copies of conference materials (with pages) that combine multiple types of manuscripts, the operator must input a serial number (number of pages) for each manuscript and make copies, or After filling in and making copies, it was necessary to either erase the serial number written on the manuscript, or make a copy without adding a serial number and then write the serial number on the copy. . Or (B) When distributing copies to multiple departments, either: ■Enter a code number indicating each department for each copy, or■Write a code number on each copy. I needed to find a way.
・ (Problem to be solved by the invention) However, in the case of (A), the pagination work, method ■ requires an extremely large amount of labor, and even if methods ■ and ■ are used,
The problem was that it required a considerable amount of effort. Also, (B)
In the case of (1) and (2), there is a problem in that the number must be updated every time a copy is made.

The present invention has been made in view of the above-mentioned problems, and its purpose is to solve problems such as when creating a number of paged materials by combining multiple types of manuscripts, or when assigning different numbers to copies of the same manuscript, etc. The object of the present invention is to realize a copying apparatus that can significantly reduce the labor required for the operation.

(Means for Solving the Problems) The present invention, which solves the above problems, provides a copying apparatus that can also copy additional information displayed on a display means when copying document information. a display means capable of displaying a date or a number; a mode selection means for displaying a date or a number on the display means; The present invention is characterized by having a number increasing/decreasing means that can automatically increment or decrement the number.

(Function) According to the present invention, when the number display mode is selected by the mode selection means, the number can be automatically incremented or decremented, so there is no need to update the number for each original or each copy.

(Example) Embodiments of the present invention will be described in detail below with reference to the drawings.

The paper feed timing signal is driven so that the leading edge of the paper coincides with the paper feed timing signal.

The transfer pole 28 transfers the toner image on the photoreceptor drum 20 to the transfer paper P.
The separation pole 29 separates the transfer paper P from the top of the photoreceptor drum 20, and the separated transfer paper P is sent to the fixing device 31 via the transfer paper conveying means 30.
After being fused and fixed by a heat fixing roller and a pressure roller, the sheet is discharged onto a sheet discharge tray 33 by a sheet discharge roller 32. After the transfer process is completed, the photosensitive drum 20
The cleaning device 34 removes the toner remaining on the drum.
However, in order to facilitate this removal, a cleaning static eliminator 35 that performs alternating current corona discharge is provided in the preceding stage. Further, a charge erasing section 36 is disposed downstream of the charging electrode 21 and faces the photoreceptor drum 20 for erasing the charge in the non-image area with light so that toner does not adhere to the non-image area. In addition, 37 and 38 are the exposed areas before charging, respectively.

This is the pre-transfer exposure area.

FIG. 6 is a diagram showing the main parts of the operation panel of the above embodiment, and the operation panel is provided on the front side of the upper surface of the main body of the copying apparatus. In this figure, 40 is a numeric keypad for setting the number of copies, etc., and the set number of copies is displayed on an LED 41. Further, 42 is a button (hereinafter referred to as the P button) used to perform thick paper fixing 1 interrupt copying and other functions, 43 is a stop/clear button, and 44 is a copy button. Furthermore, 45 is a mechanism (
46 is a power cut selection button, 47 is a magnification switching button, 48 is a zoom button, and 49 is a magnification display LED. The zoom button 48 is used to change the magnification in fixed increments when the zoom mode is set using the magnification switching button 47.

4 are density selection buttons, density down button 498
and a density up button 49b, and the selected density is displayed in seven levels on the density display LED 50.

Furthermore, numeral 51 is a mode selection button used when imprinting additional information, etc., which allows you to select: ■ a mode for imprinting the date as additional information, ■ a mode for imprinting a number as additional information, and ■ a mode for not imprinting. You can select one of the modes. By pressing this mode selection button 51 in sequence, the mode selection is performed cyclically in the order of mode ■ → mode ■ → mode ■. When mode ■ is selected, the ED 51a lights up, and when mode ■ is selected, it is turned on. When the ED 51b is lit and mode (2) is selected, neither of the LEDs 51a and 51b is lit.

The display content of the display module 4 in the date imprint mode is the display of the year, month, and day (for example, as shown in FIG. 5, 1984
1984.12.31) or the time (for example, 16:40 is 16:40).
40). If the display module 4 has a perpetual calendar function and a clock function, the keys 4b to 4
Once the time is set using e, subsequent settings become unnecessary.

On the other hand, the display content in number imprint mode is, for example, a maximum of 6 digits, and when this mode is entered, the 6th digit from the bottom of the display content is displayed in the tens place of the LED 41 for displaying the set number of sheets.
A to F corresponding to the first digit are displayed in sequence, and when A to F is displayed, enter the numerical value of each digit using the numeric keypad 40 (if it is blank, turn on the stop/clear button 43), and then When the user turns on the P button 42, this data is loaded into the display module 4 at a certain timing. FIG. 7 shows an example of setting the number 12345 (the sixth digit from the bottom is blank). In this example, the input value is displayed at the 1's digit of the LED 41 for a short period of time, and then the input value is set to a standby state for inputting the next digit.

FIG. 8 shows a configuration in which a control microcomputer 60 in the main body of the copying machine sends input setting data to the display module 4 via a buffer 61. In order to transfer this data, an 8-bit signal line is used. is used, and the data itself is expressed in 8CD code, so 4 bits (
DATAO~3) is assigned (blank, all 4 bits are at H level), and a signal D/N5ELECT indicating whether it is date data D (L) or number data N (H) is sent to the display module 4 at the rising edge of the signal D/N5ELECT. ~3) to the signal ENABLE for capturing, the signal 5TART indicating the data sending period at H level, and /S T OP,
One bit is assigned to each.

FIG. 9 shows a time chart for transferring the number data N, and FIG. 10 shows a time chart for specifically transferring the number 123456.

Furthermore, this device can change the number of the display module 4 for each copy by turning on the main switch (not shown) while simultaneously pressing the stop/clear button 43 on the operation panel and the "3" key on the numeric keypad 40. can be automatically incremented using the stop/clear button 43 and the numeric keypad 4.
By turning on the main switch while pressing the "2" key of 0 at the same time, the number on the display module 4 can be decremented for each document (change of documents is detected by opening/closing the document cover 3, etc.), and the number can be stopped/cleared. The number of the display module 4 can be fixed (locked) by turning on the main switch while pressing the button 43 and the "1" key of the numeric keypad 40 at the same time. Specifically, the microcomputer 60 writes "3" on the numeric keypad 40 into a corresponding area of a non-volatile memory (not shown) in the main body of the copying apparatus.
J.

Mode data indicating which key of r2J and rlJ was pressed during the above operation is written, and thereafter, the mode data is read every time paper is fed by the first paper feed roller 24, and new data is written if necessary based on the data. Display module 4
Increase or decrease the sending number. FIG. 11 shows a flowchart of this routine.

Further, in this embodiment, when either the date imprinting mode or the number imprinting mode described above is selected, these additional information are copied together with the document information. In other words, the toner image including additional information (
The start timing of the second paper feed roller 25 is set higher than in the conventional device so that the leading edge of the photosensitive drum 20 (on the photosensitive drum 20) and the leading edge of the transfer paper P coincide with each other. In addition, if most of the document size is used for document information, if the start timing of the second paper feed roller 25 is advanced, the end of the document information will not be copied. It is designed to perform reduced copying.

Here, when the document length in the direction of optical scanning is l, and the length of additional information is a, the appropriate magnification for reducing copying is -1/(1+a), but depending on the document size. It's rather inconvenient to manually change m each time, so it's ugly -0,90
Set it to about ~0.98.

To make a copy with the above magnification -, first the optical system (
b) Changing the focal length of the main lens 16 and moving the lens position; (b) Moving the main lens 16 and the second mirror unit 15; (c) Changing the focal length of the main lens 16 and moving the lens position. A magnified image is formed on the photosensitive drum 20 by means such as moving the mirror unit 15. The focal length of the main lens 16 can be changed by using a zoom lens as the main lens 16 or by adding an attachment lens. Further, a pulse motor is used as a method for moving the optical unit to the magnification position. For example, a home position sensor is provided and the optical unit is moved to a magnification m position by controlling a motor using the number of pulses from the home position sensor.

In this way, the optical unit moves to its initial position with the projection magnification on the photosensitive drum 20 being 1x, and also changes the scanning speed of the first mirror unit 12 to 1/M. In the copy image obtained in this way, no missing original information occurs due to insertion of additional information.

Copies produced by a copying device with the above configuration are the same as conventional general copies when additional information is not imprinted, but when dates and numbers are imprinted, the additional information is the same as the original information. It will be copied onto transfer paper. If there is imprinting, the document information is slightly reduced, but this is not a problem at all if the convenience of imprinting additional information is taken into consideration. Furthermore, when in the number imprint mode, it is possible to add a number that is incremented for each copy as shown in Figure 1 (a), or it is possible to add a number that is decremented for each copy as shown in Figure 1 (b). It can also be attached.

In the latter case, if the number of originals matches the initial setting number, the number of the copy becomes the number of pages. In the above embodiment, a reflective liquid crystal was used as a means for displaying additional information, but a transmissive liquid crystal with a light source placed on the back side may be used, or an ECD (electrochromic display) or the like may be used. May be used.

(Effects of the Invention) As explained above, according to the present invention, when creating multiple paginated materials by combining multiple types of manuscripts, when assigning different numbers to copies of the same manuscript, etc. The required labor can be significantly reduced.
