Abstract

PURPOSE:To prevent stop of a copying device due to lack of transfer paper and degradation of the picture quality by inhibiting the input of information if the total copy number in a storage part exceeds the number of copies, which can be obtained, in a transfer paper remainder detecting part. CONSTITUTION:Input information of an input part for the original number and the copy number of every original is stored in a storage part 9, and an automatic original feeding device feeds automatically originals in accordance with stored information in the storage part 9. A transfer paper remainder detecting part 10 detects the remainder of transfer paper and copies automatically originals to a determinate number of papers on a basis of stored information in the storage part 9. If total copy number information in the storage part 9 exceeds the number of copies which is discriminated in accordance with a transfer paper remainder signal of the detecting part 10 and can be obtained, information input from the input part is inhibited. Consequently, stop of the copying machine due to lack of transfer paper after copying start and degradation of the picture quality are prevented.

Description

[Detailed Description of the Invention] (Technical Field) -K TA kRIJ νKI 7 `` Product Mitsuru ← 舅su I 7 こ 卜 rj 一 百拮 し・ Δ1 Bamboo 71 child rice soup, etc. Input information is stored in the storage unit The present invention relates to a programmable copying machine ff1K that automatically feeds originals according to this stored information and automatically copies a predetermined number of sheets, and particularly relates to its input control system.

(Prior Art) Programmable copying devices such as those described above have been conventionally known, but in the prior art, when information is input into the storage unit such as copy sheet 1 & etc., the number of remaining copies that can be made is checked using the remaining transfer paper. If this is not done, the machine may stop after copying starts due to lack of transfer paper, and the image quality may deteriorate, and the copying operator must perform maintenance every time this happens, reducing the effectiveness of the programmable copying device. The disadvantage is that it cannot be used to its full potential.

(Purpose) The biggest advantage of a programmable copying machine is that the close-up operator can spend more time away from the copying machine, allowing him or her to engage in other work during that time, or to transfer multiple copying machines to one machine. The purpose of this project is labor saving and rationalization.

In view of the prior art, the present invention aims to further ensure the above-mentioned characteristics.

In other words, photo spread! The purpose of this is to prevent the stoppage of copying and the deterioration of image quality due to lack of transfer paper after printing.

(composition) The configuration of the present invention will be explained below based on an actual example shown in the drawings.

Figure 1 is the programmable undercover fl according to the 'J/- invention.

Figure 4 shows the copy information input control flow. This will be discussed later.

FIG. 5 is a control circuit block diagram of the copy process control section 20, in which 6 is a CPU, i is an I10 unit, 8 is a ROM, and 9 is a RAM for storing copy information. I10
The unit 7 is configured to receive a signal from the transfer paper remaining amount detection section 10.

This transfer paper amount detection section 10 includes three sets of level detection sections 10cL each consisting of an LED and a transistor.

It consists of 10b and 10c. For example, the level detection units 1 (1#10b, 10C) are provided on the side wall of the paper feed tray (not shown) in order from the top.If the transfer paper is loaded sufficiently, the LED and phototransistor is blocked, and the seal detection section 105.10b,
Since the output of 10c is turned off, the transfer paper RE (thickness) and the number of copies that can be made can be determined by which level detection section is turned off. An example of the table is shown below.

As can be seen cheerfully from this table, if the level detection unit 10fZ (indicated as α, the same applies hereafter) is off (therefore bSc is also off of course), there is enough transfer paper remaining, and the number of possible remaining sheets is 1
This means 000 pieces.

Similarly, if the level detecting section 10b is off, 500 copies are made, if the level detecting section 10C is off, 100 copies are made, and if all are on, there is no transfer paper and copying is not possible.

FIG. 6 shows the contents of the copy information storage section (RAM) memory shown in FIG. 5, and FIG. 6(b) shows the contents of the storage memory, but naturally they are the same.

JOB (JOB 1, F) is a combination of the number of originals and the number of copies.

FIG. 7 is a copying process diagram of a programmable/l/copying apparatus according to an embodiment of the present invention.

In the figure, the block indicated by A is the input process, and the block indicated by B
The blocks indicated by C indicate the image forming process 1C, and the blocks indicated by C indicate the conveyance process.

To explain this simply, set the number of copies and the number of originals, press the input key, and press the copy start key to start copying.
This is repeated according to the number of B. Then, the image forming process begins, and the document side undergoes exposure, development, and transfer, and the transfer paper side performs paper feeding, transportation, and image registration (registration), and the unfixed image is transferred onto the transfer paper. Ru. The paper then reaches the fixing section, where it is fixed and the copy is completed, and then delivered to a paper stacker or sorter.

Next, the control of the present invention will be explained based on FIGS. 7 and 4.

The copying work in this embodiment is to copy 5 copies of a group of 5 manuscripts with 1 attention (IJOB"l) and 10 copies of a group of 20 manuscripts with 2 attention (2JOB).

First, copying information (number of originals, number of copies) must be input into the storage section of the programmable copying device.

The input method is as shown in Fig. 7.
is turned on, the number of copies is turned on using the number key 3h, and the number of originals is set using the number key 3hlC.

Each set human power information is displayed on display parts 3f and 3 in the beat 3 diagram.
9 and JOBNO is also displayed on the display 3e. After this, the copy information of the IJOB is stored in the storage unit 9 by turning on the person 30, but in the present invention, at this point, each 1-bell detection unit 10α of the “transfer paper cost” detection unit 10 is stored in the storage unit 9. , 10b110c (central control unit) (0,P
, U) 6 compares the set number of remaining copies and the total number of copies (5×5-25 copies) from the combinations shown in the table according to the control program in the ROMB. As a result, if the total number of copies is less than the set number of copies, the input 1# information is stored in ij (fl+9).

If the total number of copies is greater than the ftU era setting number L', the input copy information becomes invalid and is not stored in the storage unit 9.
Transfer paper remaining warning display G;)1α is lit.

Next, input the copy information for the second job using the same method as described in fJrJ. The input information is the total number of copies (I
JOB+2JOB) is checked.

After inputting the copy information, when the copy start key 3d is turned on, copying starts at step 7''.

Thereafter, the copying apparatus executes a feeding and conveying process, an image forming process, and a fixing process as shown in FIG. 7 in accordance with the copy control program stored in the ROMB of the control section 2, and the copies are sorter-herited.

Thereafter, feeding, conveyance, image formation, fixing, and sorting are automatically repeated until the total number of copies (225 copies), which is the copy information stored in the storage section 9, is exhausted.

During this time, the copying operator can leave the copying machine and perform other tasks.

By implementing the present invention in this way, the copying machine will not be stopped due to lack of transfer paper during copying, and the copying operator can safely engage in other tasks or manage other copying machines while copying is in progress. The effects of streamlining and labor saving in the copying work of the copying device can be fully demonstrated.

(Effects) The present invention is as described above, and when inputting copy information to a programmable copying device, the total number of copies of copy information in the storage unit and the remaining amount of transfer paper from the remaining amount of transfer paper detection unit are detected. When the total number of copies exceeds the number of remaining copies determined from the signal, the machine is stopped due to lack of transfer paper after copying has started. , and image quality deterioration can be prevented in advance, and the time when a copying operator can be away from the copying device is ensured, and the effect of labor saving and rationalization of copying work of the programmable copying device is further ensured. I can do it.
