Abstract

PURPOSE:To permit the free use of the captioned apparatus by cutting off a paper passage communicating to a collating apparatus by a paper discharging instruction after the release of paper clogging and discharging the paper left in a copying machine into a discharge tray by a paper transporting means. CONSTITUTION:When a start switch is turned-ON after the cause of clogging of paper sheet is removed, a solenoid 22 is operated to allow a switching gate 23 to communicate to a removing passage 25 side, and at the same time, a sorter motor 31 is driven. Therefore, the paper left in a copying machine 10 is discharged into a discharge tray 24 through the removal passage 25. When a sensor 15 does not detect the paper for a prescribed time, no existence of the paper left is judged, and the switching gate 23 returns to a sorter passage 26 side. With such constitution, the need of selecting the paper left after clogging is avoided.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a control device for a copying machine with a collating device that eliminates the trouble of sorting between usable copy paper and unusable copy paper when a paper jam occurs. Regarding.

[Conventional technology]

As a conventional copying machine with a collating device, for example,
There is one shown in Japanese Patent No.-186871. In this copying machine equipped with a combination device, a plurality of presser pieces are stacked on the copy paper ejection section, and chains hooked to sprockets arranged above and below are connected to support members provided above and below the presser pieces. By connecting one of the sprockets to a prime mover and reciprocating the sprocket, the chain and the plurality of presser pieces are reciprocated in the vertical direction in synchronization with the ejection of the copy paper.

In the above configuration, the plurality of contact surfaces formed by the plurality of pressing pieces are sequentially opened by the protruding pieces, and the copy sheets are fed into the discharge tray through the contact surfaces, thereby sorting the copy sheets.

[Problem that the invention seeks to solve]

However, with conventional copying machines equipped with a collating device, when a paper jam occurs, if the copy paper that caused the paper jam (hereinafter referred to as the cause of the jam) is removed and the copying machine is restarted, the remaining paper remains in the copying machine. Since the copy paper used in the machine is now discharged to the sorter section, it is necessary for the operator to sort out the copy paper that can be used by himself and the copy paper that cannot be used.

[Means and effects for solving the problems] The present invention has the following features:
This was done in consideration of the above, and in order to eliminate the troublesome process of sorting between usable copy paper and unusable copy paper when a paper jam occurs, the copy paper remaining in the copier when the cause of the jam is removed is removed. The present invention provides a control device for a copying machine with a collating device, which discharges the information to a place other than the sorter.

〔Example〕

Hereinafter, the control device for a copying machine with a collating device according to the present invention will be explained in detail.

FIG. 1 shows an embodiment of the present invention, in which a copying machine main body 10 includes a paper feed tray 1 that stores copy paper to be fed to a transfer section.
6, a paper passage 13 through which copy paper passes, a solenoid 11 for switching a switching gate 2 (to be described later), the switching gate 12, which becomes a discharge passage 17 when not sorting, and a sorter passage 18 when sorting, and a solenoid 12 which switches a switching gate 2, which will be described later. an output tray 14 that accommodates copy paper;
Paper path sensor (photo separator) that detects the passage of copy paper
A sensor) 15 is provided.

The sorter unit 20 includes a sorter bin 21 that sorts and stores copy paper, a solenoid 22 that switches a switching gate 23 (described later), and a sorter passage 26 that serves as a removal path 25 when a paper jam occurs and feeds the paper into the sorter bin 21 in normal conditions.
The copying machine has the switching gate 23, which is the switching gate 23, and an ejection tray 24 from which copy paper is ejected in the event of a paper jam or the like.

FIG. 2 shows a control section 30 provided in the copying machine body 1O or the sorter section 20, which includes an input interface for inputting the sensor signal of the paper path sensor 15, a RAM for temporarily storing data, etc., and the switching gate. ROM that stores programs etc. for driving the solenoid 22 or the sorter motor 31 (which conveys the paper in the paper path 13)
and a CPLJ that performs predetermined arithmetic processing based on the program in the ROM and outputs a control signal via an output interface.

The operation will be explained in the above configuration.

(b) When the start switch is turned on when not performing a sorting operation, copy paper is fed from the paper feed tray 16, and the copy paper copied by a predetermined copy operation passes through the paper path 13 to the resolenoid 11.
(switching gate) 12 which was switched to the discharge passage 17 by
The main body is discharged through the main body discharge tray 14.

(b) When performing a sorting operation (flow chart in Figure 3) When the start switch is turned on, copy paper is fed from the paper feed tray 16, and the copy paper that has been copied by the predetermined copy operation passes through the paper path 13. , solenoid 1
The predetermined sorter bin 2
It is accommodated in 1.

If a paper jam occurs during a sorting operation, the copier will stop. When the start switch is turned on after removing the cause of the jam based on the paper jam display (copy paper discharge command is issued), the solenoid 22 is activated and the switching gate 2 is turned on.
3 is a removal passage 25.

At the same time, the sorter motor 31 is driven and the copy paper remaining in the copying machine main body 1O is discharged to the sorter discharge tray 24 through the removal passage 25. The passage of this copy paper is detected by the paper path sensor (photo sensor) 15, and the paper path sensor 15 is detected for a predetermined time T.
When no copy paper is detected, the operation of the solenoid 22 is stopped and the switching gate 23 returns to the sorter passage 26. After this, the sorting operation is performed again.

〔Effect of the invention〕

According to the control device of the copying machine with a collating device of the present invention, the copy paper remaining in the copy machine is discharged to a place other than the sorter after removing the cause of the jam, so that copy paper can be used when a paper jam occurs. This eliminates the troublesome effort of sorting unusable copy paper.
