Abstract

PURPOSE:To copy two originals to the same form at different positions and also display the number of times of copying operation by taking a copy to the half part of the copy form in the 1st copy cycle and holding it in a repetitive copy tray part, and taking a copy to the remaining half part in the 2nd copy cycle and display the copy area. CONSTITUTION:When a repetitive copy key is pressed and magnification corresponding to an original and a form is set, a size recognition part 15 recognizes the size of the copy form to select either of trays 2 and 2' and feed paper, and also send out a form side signal to a repetitive copy mode control part 16 and a mode signal to a CPU13. The CPU13 reads a display pattern out of a ROM12 and sends it to a display control part 19, which makes a panel display 20. A reduced copy is taken to the half part of the form, which is held temporarily in the repetitive copy tray 15. When the 1st copy cycle ends, a next copy area is displayed 20 with a signal from the control part 16 and the 2nd copy cycle is started to copy the 2nd original to the remaining half part of the form.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a copying machine control system, and in particular, after an original is copied onto half of a copy paper by scale copying or the like, the remaining half is copied in the next copy cycle. Concerning what you want to copy into parts.

[Prior art]

As shown in Figure 1 (al), originals P and Q may be reduced by 70% and then copied side by side on copy paper of the same size as shown in (bl). When making such copies Conventionally, the originals P and Q are arranged adjacent to each other on a platen, and then the originals P and Q are pressed against the original holding plate before copying is performed.

By the way, when the originals P and Q are sheet materials, when the originals P and Q are placed next to each other on the platen and then pressed with the original pressing plate, these originals P and Q tend to shift easily, making it difficult to make high-quality copies. This was difficult, and in some cases it was necessary to lightly adhere the manuscripts P and Q with adhesive tape or the like in advance.

Therefore, instead of arranging the two originals P and Q and copying them all at once, there has been a demand for copying the originals one by one to obtain high-quality copies.

Moreover, when copying a document twice, one sheet at a time, it is necessary to display to the user which section is currently being copied and what number of copies it has been made.

[Purpose of the invention]

An object of the present invention is to make it possible to copy two originals one by one on the same sheet of paper with different positions, and to make it possible to make copies of two originals, one by one, on the same sheet of paper, in order to satisfy the above-mentioned requirements. An object of the present invention is to provide a copying machine control method that displays the information.

[Structure of the invention]

To achieve the above object, the copying machine control system of the present invention is provided with a double copying tray section, and after copying on half of the copy paper in the first copy cycle, this is held by the double copying tray section, In the second copy cycle, copies are made to the half-copied remaining portion held in this duplicate copy tray section, and a display is displayed on the display section 9 to identify whether it is the first copy or the second copy. be.

This not only makes it possible to copy two originals A and B one by one on the same copy paper as shown in Figures 2 (al, (bl), but also makes it possible to copy two originals A and B one by one on the same copy paper, as shown in Figures 2 (C1, (d ), it is possible to easily recognize whether the current copy cycle is the first copy cycle or the second copy cycle.9
For example, it is possible to prevent an erroneous operation in which a copy is not ejected because the first copy cycle is not repeated for the 22nd time.

〔Example〕

An embodiment of the present invention will be described based on FIGS. 3 and 4 and with reference to FIG. 2.

FIG. 3 is a block diagram of an embodiment of the copying machine of the present invention, and FIG. 4 is a block diagram of its control circuit.

In the figure, 1 is a photosensitive drum on which a latent image of a document is formed and this latent image is developed.

2.2' is the paper feed tray on which sheets of different sizes are set, and 3.3' is the first feed φ roller.

4 is a fuser, 5 is a tray unit for duplicate copying, and as shown in FIG.
The feed roller is the tray section 5 for duplicate copying.
7 is a paper detector for detecting the copy paper sent out from the duplicate copy tray section 5; 8 is a delay control section which will be described later. 9 is a control device in which the main parts of the control circuit shown in FIG. 4 are housed.

10 is an automatic document feeder, and 11 is a copy receiver.

12 is ROM (Read Only Memory
), which stores programs necessary to control the operation of this copying machine and various display data to be displayed on the panel display section 20, and 13, a processor for various controls for operating the copying machine. 9 is configured by a microprocessor, for example, and 14 is an R
A M (Random Access Memory
) which acts as a main memory; 15 is a size recognition unit which recognizes the size of copy paper;
16 is a duplicate copy mode control section.

As shown in FIG. 2, 17 is a scale recognition unit that outputs a control signal when copies are made twice on the same copy paper, in which copies are made on the same side of the same paper in different cycles. 18 is a delay conveyance section which delays the conveyance operation of copy paper and has a conveyance path for one sheet of paper, for example; 19 is a display control section which outputs a message on the panel display section 20. It performs various controls for displaying etc. Reference numeral 21 denotes a paper detector, which detects the insertion of copied paper into the duplicate copy tray section 5.

The delay control unit 8 is configured as shown in FIG.
When copy A' held in the duplicate copy tray section 5 copies original B on the copied paper, copy B' is prevented from being duplicated on copy λ without adjustment. Copy A is performed by delaying the paper feeding time to the photosensitive drum 1 only in the area where copy A' was made.
The adjustment is made so that copy B' is performed next to copy B'. Therefore, since this delay time varies depending on the paper size, the time required to send out the corresponding paper is increased, and the delay operation is performed by adjusting the rotational speed of two transport rollers (not shown). As a result, the paper is fed at a reduced conveyance speed from, for example, the vicinity of the paper detector 7 to the photosensitive drum 1, and adjustments are made so that copy B' is performed on the blank area of the remaining sheet of copy A'. become.

Of course, the timing of sending out the second feed roller and
Even if the conveyance speed from the outlet of the duplicate copying tray section 5 to the photosensitive drum 1 is adjusted according to the paper size, copying B' can be performed on the blank area.

The panel display section 20 displays various messages to the user.9For example, when performing duplicate copying as shown in FIG. 2, if the user presses the duplicate copy key, the second
As shown in Figure (C1), only the portion a to be copied first is displayed as a lit button, and when a sheet is inserted into the tray section 5 for one-double copying, the sheet detector 21 detects this.

As shown in FIG. 2 Fdl, the blank space is displayed by lighting.

Next, the operation of the present invention will be explained.

(1) When making separate copies on one side (duplicate copy mode) The user presses the duplicate copy key and selects the scale rate according to the original and paper. (70% when copying an A4 original onto A4 paper) )do. As a result, the size recognition unit 15 recognizes that the copy paper size is A4 and operates to feed the A4 paper from either tray 2 or 2'. to send out that the paper size is A4. Further, the redundant copy mode control unit 16 reports to the processor 13 that it will be operated in redundant copy mode.

Accordingly, the processor 13 reads the corresponding display pattern from the ROMI 2 and sends it to the display control section 19.
As shown in FIG. 2(C), a display in which only a, which is to be copied first, is lit is displayed on the panel display section 20.Next, when the user inserts the document A into the automatic document feeder 10, the copy begins as is well known. It will be done. At this time, Fig. 2 Ca
As shown in FIG. 1, a 70% scaled copy λ is performed, and the copy paper is controlled so that its conveyance path is closed at the end of the fixing device 4, with the copy tray section 5 side being empty and the copy receiving section 11 side being closed. 2 duplicate copy tray section 5
It is carried inside and held there. At this time, the paper detector 21 outputs a paper detection signal, so the 1-duplication copy mode control unit 16 detects the end of the first copy cycle to the processor 1.
Report to 3. As a result, the processor 13 uses the ROM 12
The display pattern corresponding to the second copy cycle is read out from the display control unit 19 and sent to the display control unit 19.

This time, as shown in FIG. 2(d), a display is performed in which b, which is to be copied nine times, is lit.

When the user inserts a second document into the automatic document feeder 10, a second copy cycle begins. Then, the image formed on the photosensitive drum 1 is adjusted to be correctly transferred onto the paper by the delay conveyance unit 18 according to the paper size, so that duplicate copies can be obtained as shown in FIG. 2(b).

In the second copy cycle, since the copy receiver 11 side of the conveying path is located beyond the fixing device 4, the copied paper is sent out to the outside of the copying machine.

In the above description, an example in which the scale ratio is 70% has been described, but for example, when copying a B5 original onto B4 paper, two sheets of the original can be copied on the same side without scaling.

〔Effect of the invention〕

According to the present invention, by using the double copy mode and image shift, it is possible to copy two originals on the same side in two cycles, so that not only a high quality copy can be obtained, but also the operation state can be displayed externally, preventing erroneous operations.
