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, when creating the desired number of copies of meeting materials (with pages) by combining multiple types of manuscripts, the operator must give a serial number (
(number of pages) and make a copy, or ■ Enter a serial number for each manuscript and make a copy, then delete the serial number written on the manuscript, or ■ Make a copy without adding a serial number and make a copy. It was necessary to either write serial numbers on the items or to use one of two methods.

(Problems to be Solved by the Invention) However, in the case of the above-mentioned pagination work, there is a problem that method (■) requires an extremely large amount of labor, and even methods (■) and (■) require a considerable amount of labor. Ta.

The present invention has been made in view of the above-mentioned problems, and its purpose is to realize a copying device that can significantly reduce the labor required for creating multiple paginated materials by combining multiple types of manuscripts. It's about doing.

(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. The present invention is characterized by having a display means capable of displaying a number, and a means capable of automatically decrementing or incrementing the number displayed on the display means for each document.

(Function) According to the present invention, since the display number can be automatically decremented or incremented for each manuscript, the number 8 can be used as the number of pages. This eliminates the need to update the number for each document.

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

There is. The main lens 16 allows the reflected light from the original on the original placing table 1 to pass through the first mirror 11. 2nd mirror 1
The light exiting the main lens 16 passes through the fourth mirror 17 and enters the slit 1 onto the photoreceptor drum 20 as an image support.
The light is made to enter through ``8''.

The charging electrode 21 uniformly charges the photosensitive drum 20 with an electric charge. Therefore, electrostatic latent images are sequentially formed on the photoreceptor drum 20, which rotates clockwise in FIG. 2, due to the incidence of light from the optical system. The developing device 22 converts the electrostatic latent image on the photosensitive drum 20 into a visible toner image.

On the other hand, the paper feeding device that feeds the transfer paper includes a paper feed cassette 23 (here, two are illustrated) that accommodates the transfer paper P, and a first cassette that feeds the transfer paper P one by one from the paper feed cassette 23. A paper roller 24, a second paper feed roller 25 that feeds the transferred transfer paper P to the photosensitive drum 20, and a space between the paper feed cassette 23 and the second paper feed roller 25 and the second paper feed roller It consists of guide plates 26 and 27 arranged between a paper roller 25 and a transfer pole to be described later. When copying,
The transfer paper in the selected paper feed cassette 23 is fed out by the first paper feed roller 24, guided by the guide plate 26, and reaches the second paper feed roller 25. The leading edge of the toner image on 20 and the transfer paper P
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 is used to separate the transfer paper P from the photosensitive drum 20, and the separated transfer paper P is sent to the fixing device 31 via the transfer paper conveyance means 30.
After being fused and fixed by a heat fixing roller and a pressure roller, the paper is discharged onto a paper discharge 133 by a paper discharge roller 32. After the transfer process is completed, the photosensitive drum 2
0 is a cleaning device 3 that removes toner remaining on the drum.
4, but to facilitate this removal,
A cleaning removal electrode 35 for performing alternating current corona discharge is provided at the front stage thereof. 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 LED 41. Further, 42 is a button (hereinafter referred to as P button) used for 9-interrupt copying with thick paper fixing and other functions, 43 is a stop/clear button, and 44 is a copy button. Furthermore, 45 is an auto mode button used to operate a mechanism (ΔPS) that detects the document size and automatically determines which size of transfer paper to feed, 46 is a cassette selection button, and 47 is an auto mode button. Magnification switching button, 48 is a zoom button, 52 is a magnification display LED
It is. The zoom button 48 allows the magnification to be changed in fixed increments when the zoom mode is set using the magnification switching button 47, and 48a is an enlargement button and 48b is a reduction button. Reference numeral 49 denotes a density selection button, which consists of a density down button 49a and an m degree 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 sequentially, the mode is selected cyclically in the order of mode ■ → mode ■ → mode ■. When mode ■ is selected, the LED 51a lights up, and when mode ■ is selected, the mode is selected. L
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
Displaying December 31st, 2014 as 1984.12.31) or displaying the time (e.g. Eva, displaying 16:40 as 16.40).
40). If the display module 4 has a perpetual calendar function and a clock function, the keys 4b to 4
By using e to set whether to display the year, month, day or time, and to adjust the time, subsequent settings become unnecessary.

On the other hand, the display content in the number imprinting mode is, for example, a maximum of six digits. When this mode is entered, displays A to F indicating the 6th to 1st digits from the bottom of the number to be entered in the tens digit of LED 41 for displaying the set number of sheets will be displayed in order. ~ When F is displayed, press numeric keypad 4
Enter the numerical value of each digit with o (if blank, turn on the stop/clear button 43), and finally turn on the P button 42, this setting number will be read into the control microcomputer inside the copying machine body, which will be described later. From there, the number to be displayed on the display module 4 is sent. FIG. 7 shows an example in which the number 12345 is set (the sixth digit from the bottom is blank).

In this embodiment, the number of originals is input as the value of the setting number. In this example, the input value is displayed for a short time in the 1's digit of the LED 41, and then the next digit is input 4! The device is configured to move to a machine state.

FIG. 8 shows that a control microcomputer 60 in the main body of the copying apparatus transmits data to the display module 4 via a baranoa 61.
Although the configuration for sending data to the data is not shown, a signal line for 8 bits is used for each transfer of this data, and the data itself is expressed in a BCD code, so 4 bits < DATAO
~3) are assigned (all 4 bits are blank at level 1), and date data D (L) or number data N (1-
1) Signal D/N5ELECT' (if the display module 4 does not have a clock function etc., the microcomputer 60 obtains date data from the clock module etc. and sends it to the display module 4. In this case, it is also possible to transfer date data.
(The configuration using the N5ELECT signal is shown), the signal ENABLE for causing the display module 4 to take in data (DATAO~3) at the rising edge, and the signal 5TART/5TOP indicating the data transmission period at H level, each one bit is set. Assigned. Figure 9 shows a time chart for transferring number data N, and Figure 10 shows number 1.
A time chart for specifically transferring 234.56 is shown.

Furthermore, this device can decrement the number on the display module 4 for each document by simultaneously pressing the stop/clear button 43 on the operation panel and the "2" key on the numeric keypad 40 and turning on the main switch. For example, the number of the display module 4 can be fixed by turning the main switch A" while pressing the stop/clear button 43 and the r1J key on the numeric keypad 40 at the same time. Specifically, the microcomputer 60 can lock the
"2" on the numeric keypad 40 is placed in the corresponding area of the non-volatile memory (not shown) within the main body of the copying apparatus.

Write mode data indicating which key "1" was pressed during the above operation, read the mode data every time the first paper feed roller 24 feeds the paper, and write new data if necessary based on the data. is sent to the display module 4 to change 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 advanced compared to 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. 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 length of the document 11 in the optical scanning direction and the length of the additional information is a, the magnification l for reduction copying is m = 1! / (Il+a) is appropriate, but it is rather inconvenient to manually change m depending on the document size, so 111=0.
Set it to about 90 to 0.98.

In order to make a copy with the above magnification m, first, the optical system is equipped with a mirror unit (12), (a) the focal length of the main lens 16 is changed and the lens position is moved, (b) the main lens 16 and the second mirror unit 15 are (c) changing the focal length of the main lens 16 and moving the second mirror unit 15 so that an image with a magnification of m is formed on the photoreceptor drum 20-H. 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 is moved to its initial position with the projection magnification on the photosensitive drum 20 multiplied by 1, and the scanning speed of the first mirror unit 12 is changed to 1, . . . /Ill. In the copy image obtained in this way, no missing original information occurs due to insertion of additional information.

Copies made by the copying device with the above configuration are the same as conventional general copies when additional information is not imprinted, but when the date and scent are imprinted, the additional information is the same as the original information. - Transfer paper - will be copied on paper.

If there is imprinting, the manuscript information is reduced to a celebrity size, 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, for example, if the number of originals is 10 and the set number of copies is 5, inputting 10 as the setting number and setting the set number of copies to 5 will print the image in Figure 1. As shown, a decremented number can be assigned to each document. In this case, since the number of original sheets and the setting number match, the number of the copy becomes the number of pages. In the above explanation, an example was shown in which copying started from the last page of the original (original 1 in Figure 1 is the last page), but this is because it is adapted to use the automatic document feeder (ADIN). .Therefore, the first page of the manuscript is
．． When copying from s +, the setting number may be set to 1 and the setting number may be incremented.

Further, 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 also be used, or an ECD (electrochromic display) or the like may be used. may also be used.

(Effects of the Invention) As described above, according to the present invention, when a plurality of paginated materials are created by combining a plurality of types of manuscripts, the labor required for the work can be significantly reduced.
