Abstract

PURPOSE:To eliminate the need for removing operation and save labor by discharging the copy set in a compiler tray to discharge tray automatically when a jamming form is detected. CONSTITUTION:When a jam detection sensor 25 detecting a form to be send to the compiler tray 15 being jamming and the copy set is almost discharged after a stapler 17 is driven, a gate 16, motor 24, and conveyor roller 18 are each turned on for a specific time. The copy set in the tray 15 falls on the roller 18 gravitation and is sent out to a guide mechanism 19 by the roller 18 and further discharged to the discharge tray 20 by the mechanism 19.

Description

[Detailed Description of the Invention] [Technical Field] The present invention provides a system in which when a finisher jam occurs when a stapled copy set is in a container or an in-tray, the compiler tray automatically ejects the Sycoby set and then drives it. Finisher that stops the mechanism
[Prior art] As a copying machine equipped with a conventional finisher, for example,
The document is continuously fed to the grating, the copy paper is fed accordingly to make copies, and the ejected copied paper is sequentially fed to the compiler tray of the finisher, and the copy paper is sequentially fed to the compiler tray of the finisher.
There is one that can be stapled with r) to make copy sets.

When stapling, set the console to sister pull mode, set the r-number necessary for copying, press the start button to start copying, and the document will be fed to the automatic document feeder at regular intervals. Copies are made on copy sheets that are fed sequentially in response to the copy sheets supplied to the printer. The ejected copy paper is sent to a finisher, and after the copy paper for the number of original documents is supplied to the compiler tray, the stapler is operated and stapling is performed. As described above, stapling is automatically performed after the copy paper is ejected, so that it is possible to save labor.

However, in a copying machine equipped with a conventional finisher, when a jam (JAM) has occurred in the paper to be stapled that has been conveyed to the finisher, the entire drive mechanism of the finisher is activated. To stop
There was an inconvenience in that the operator had to take out the stapled paper (print set) in the compiler tray by hand.

[Object and structure of the invention]

The present invention has been made in view of the above, and in order to automatically eject the print set in the compiler tray when a jam is detected, the drive mechanism and dart are set in a predetermined manner upon detection of the occurrence of a jam. To provide a copying machine equipped with a finisher which is driven for a period of time to automatically discharge a print set in a compiler tray to a discharge tray.

〔Example〕

Hereinafter, a copying machine equipped with a finisher according to the present invention will be described in detail. FIG. 1 shows an embodiment of the present invention. -10. The finisher 10 has a transport port 211 that transports paper from the discharge row 22, and selectively distributes the paper supplied from the transport port 211 to either the discharge tray or the tray 4 and 2. A separating filler lever 12, a paper sensor 13 that detects the passage of paper when the selector 12 is in the lower 1 position, and a transport port that allows the paper that has passed through the paper sensor 13 to fall naturally as it passes through the transport end, -214. and a tray 15 that sequentially receives and stops the sheets falling through the row 214.
and an r-tray 16 provided at the lower end of the tray 15 to keep the paper in the tray until stapling is completed;
A stapler puller 17 staples a predetermined portion of the paper bundle supplied to the compiler tray 15, and a conveyor roller transports the paper that is naturally discharged from the tray 5 when the r-) 16 is opened. 18, and the paper (
a guide mechanism 19 that guides a paper ejected from the guide mechanism 19 (or a copy set), an ejection tray 20 that receives and places the paper ejected from the guide mechanism 19, the paper size, the number of copies, the reduction ratio,
A console 21 is provided with a button for setting the mode, etc., and a display for displaying the operating status, number of copies, etc., and a finisher 10 based on information and data from the sensor and the console 21. A control section 22 outputs control commands for controlling the copying machine main body 1, and a finisher. Whether or not a jam has occurred in the drive unit 23 that drives the motor 24 for driving each conveyance roller in 10, the selector 12, r-) 16, and the staple puller 17, and the paper conveyed through the conveyance port 211. The jam detection sensor 25 is configured to detect jam detection.

The control unit 22 includes an input interface 22b that inputs information and data from various sensors, the paper sensor 13, the jam detection sensor 25, and the console 21, and sends the digitized signal to the path 22a at a predetermined timing; A ROM 22 c that stores programs for copying and stapling, and a CPU 22 that executes various processes according to the programs in the ROM 22 c.

The output interface 22f outputs control commands to the drive unit 23 at a predetermined timing and format.

In the above configuration, the originals are sequentially supplied to the platen by an automatic document feeding device (not shown), and the paper is fed from a paper feed cassette (not shown) in synchronization with the progress of scanning and development. Copies are made according to the number of original sheets. The sheet on which copying has been completed reaches the general feed row 22 via the conveyance path, and is sent to the finisher 10 by the roller 2. The supplied paper is sent to the latter stage by the conveyance roller 11, but the paper is not conveyed to the console 2.
When the stelasol mode is selected by 1, the transport row 21 is
Sent to the 4th side. When the Stellanol mode is off, the selector 12 is set to the upper position, and the paper from the conveyance roller 11 is sent to the guide mechanism 19, which is provided at the exit of the mechanism 19. The sheets naturally fall through the conveyance rollers onto the discharge tray 20 and are stored one after another.

The paper fed into the conveyance roller 14 is sequentially fed into the compiler tray 15 from the leading edge of the paper, and the trailing edge is taken out and slides down on the tray 15, r-
It is placed on the seat 16 with its tail end locked. When the paper sensor 13 detects that the number of original sheets has passed, the control section 22 outputs a command to operate the stapler 17 to the drive section 23 . When the stapling of the Stella Blur 17 is driven by the drive unit 23 and stapling is performed normally, a command to open the control unit 22 (9r7) 16 is output to the drive unit 23, and the guide mechanism 1

Incidentally, a jam detection sensor 25 monitors whether or not a jam occurs in the paper while it is being fed from the conveyance roller 11 to the withdrawal roller 14. Conventionally, the entire drive mechanism of the finisher 10 was controlled to stop at the same time as a jam was detected, but in the present invention, the second
The processing shown in the flowchart in the figure is executed.

That is, when the jam detection sensor 25 detects that a paper to be sent to the blank tray 15 is jammed, and after the Stellar Blur 17 is driven, the copy set is about to be dispensed. dirt 16

a few seconds). With this control, con/? The copy set in the illustration tray 15 naturally falls onto the conveyance roller 18, is sent to the guide mechanism 19 by the conveyance roller 218, and is then delivered to the discharge tray 20 by the guide mechanism 19. Note that even if there is paper in the compiler tray 15, if it is not stapled, the r-)16
, motor 24 and transport roller 18 are not driven and the paper is stored until removed by the operator.

〔Effect of the invention〕

According to the above-described copier and the copying mode equipped with the finisher of the present invention, when a jammed sheet is detected, the copy set in the four-color tray is automatically ejected to the output tray. This eliminates the need for removal work by the operator, resulting in labor savings. Additionally, since there is no need to touch the inside, there is no risk of an accident, and safety is improved.
