Abstract

PURPOSE:To allow a copy processor to perform copy processing without causing any paper jam even when a copying machine whose copying speed is faster than the processing speed of the copying processor is connected by allowing the copying machine to start copying operation after receiving a response from the copy processor. CONSTITUTION:When a form sensor 10 detects copying paper and outputs a sensor signal, a motor 9 drives a feeding-in means to send copying paper in a processing part 8, which exemplifies a transcript, an abstract, etc. When the copying machine A takes another copy during the processing, a circuit 20B outputs a response signal to a circuit 20A at the precedent timing where no paper jam occur even if the copy processor C receives the finished copying paper. When the circuit 20A inputs the response signal, the copying machine A is allowed to take the next copy. Thus, the copying machine take copies one after another and they are processed by the processor C, and a series of copying operations is completed when a specific number of copies are taken.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is designed to prevent problems such as paper jams from occurring in the copy processing machine even when a copy machine with a faster copy speed than the processing speed of the copy processing machine is connected. The present invention relates to a control device for a copying machine equipped with peripheral equipment capable of performing copying processing to create certified copies, extracts, etc. without any need for copying.

[Conventional technology]

As a conventional control device for a copying machine equipped with peripheral equipment, there is one disclosed in, for example, Japanese Patent Laid-Open No. 121060/1983. As shown in FIG. 4, this control device includes a copying machine A that copies an original onto copy paper, a copy processing machine B that processes copies made by the copying machine A, and a copy processing machine B that processes copies made by the copying machine A. It has a transport section C that transports paper to a copy processing machine B.

The copying machine A has a document table 1 on which originals are placed, a paper feed tray 2 that stores copy paper, a transfer section 4 that transfers the toner image on the photosensitive drum 3 onto the copy paper, and a unit that fixes the transferred image on the copy paper. and a first paper sensor 6 that detects passage of the fixed copy paper. (Other parts are self-explanatory and will not be explained).

The copy processing machine B includes a paper tray 7 that stores the copy paper copied by the copy machine A, a processing section 8 that performs copy processing to produce certified copies, extracts, etc., and a processing section that transfers the copies from the paper tray 7 to the processing section 8. It is comprised of a motor 9 that drives a feeding means that feeds the copy paper into the paper tray 8, a second paper sensor 10 that detects copy paper on the paper tray 7, and a lid 11 that opens and closes to take out the copy paper.

The conveyance section C has a conveyance belt 12 that conveys the copy paper copied by the copying machine A to the copy processing machine B.

A control circuit 20 (for example, a microcomputer) is provided to control the operations of the copying machine A, copy processing machine B, and transport section C described above. Sensor signals are input to the control circuit 20 and various control signals are sent to the control circuit 20. Output. For example, sensor signals from the first and second paper sensors 6.10 are input, and a control signal for controlling the drive of the motor 9 is output.

In the above configuration, when the original is placed on the original platen I and the start switch is turned on, the specified copying operation starts.
A toner image is transferred to copy paper fed from a paper feed tray 2 in a transfer section 4, and the toner image is fixed in a fixing section 5. After the copied copy paper passes over the first paper sensor 6, it is ejected from the copying machine A, and is sent onto the paper tray 7 in the copy processing machine C by the conveyor belt 12, and then transferred to the second paper sensor 6.
It is detected by the paper sensor 10. When the second paper sensor 10 outputs a sensor signal due to this detection, the motor 9 drives the feeding means to transfer the copy paper to the processing section 8.
The processing unit 8 performs processing to create a certified copy or an extract.

When the copying speed of the copying machine A is faster than the processing speed of the copying processing machine B, when the second paper sensor 10 detects copy paper that has arrived on the paper tray 7, the first paper sensor 6
When the next copy paper is detected, the control circuit 2
0 inputs each sensor signal and outputs a control signal to stop the motor 9. This allows motor 9
Since the machine stops, copies of copied paper are piled up one after another on the paper tray. When a predetermined number of copies have been made, the lid 11 is opened and the copy paper stacked on the paper tray 7 is taken out.

[Problem that the invention seeks to solve]

However, according to the control device of a copying machine equipped with conventional peripheral equipment, if the copying speed of copying machine A is faster than the processing speed of copying processing machine B, the motor 9 will stop and processes such as copying and extracting cannot be performed. Therefore, there is an inconvenience that such processing work must be performed manually.

[Means and effects for solving the problems] The present invention has been made in view of the above, and even when copying machine A having a faster copying speed than copying processing machine B is connected, the copying process can be completed. In order to be able to perform copy processing operations such as creating certified copies and extracts without causing problems such as jams on the machine, we have installed a peripheral device that allows the copier to start copying after receiving a response from the copy processing machine. The present invention provides a control device for a copying machine equipped with the following functions.
