Description

[Detailed Description of the Invention] [Technical Field] The present invention includes a finisher that can automatically eject copy paper in a compiler tray when the staple mode is canceled due to a stoppage of the apparatus immediately before stapling. Concerning copying machines.

[Prior art]

As a copier with a conventional finisher,
For example, a document is continuously fed to a platen, and copy paper is fed accordingly to make a copy.
The output copied paper is sequentially fed to the compiler tray of the finisher.
Staple with a stapler,
There are some that allow you to perform copy sets.

When stapling, set the staple mode from the console, set the data necessary for copying, press the start button to start copying, and the automatic document feeder feeds the document to the platen at fixed time intervals. In response to this, copies are made on copy sheets that are sequentially fed. The ejected copy paper is sent to the finisher, and after the number of copy papers for the original is supplied to the compiler tray, the stapler is activated to perform stapling. As described above, stapling is automatically performed after the copy paper is ejected, so that it is possible to save labor.

However, with conventional copiers equipped with a finisher, if the staple mode is canceled for some reason (such as the stop button being operated during staple mode), stapling will no longer be performed. The operator had no choice but to take it out manually.

[Object and structure of the invention]

The present invention has been made in view of the above,
When staple mode is canceled due to an interrupt such as pressing the stop button or interrupt button just before stapling, copy paper in the compiler tray is automatically ejected to the output tray. For,
To provide a copying machine equipped with a finisher that automatically discharges copy paper in a compiler tray on the condition that an all clear button is pressed.

〔Example〕

Hereinafter, a copying machine equipped with a finisher according to the present invention will be explained in detail.

FIG. 1 shows an embodiment of the present invention, which comprises a copying machine main body 1 equipped with a discharge roller 2 for discharging copied paper, and a finisher 10.
The finisher 10 includes a transport roller 11 that transports the paper from the ejection roller 2, a selector 12 that selectively distributes the paper supplied from the transport roller 11 to either the ejection tray or the compiler tray, and the selector 12 located at the lower position. a paper sensor 13 that detects the passage of paper when the paper is at the paper sensor 13, a transport roller 14 that allows the paper that has passed the paper sensor 13 to naturally fall as it passes the end of the transport, and a compiler that sequentially receives the paper that falls through the roller 14. A tray 15, a gate 16 provided at the lower end of the tray 15 to keep the paper in the tray until stapling is completed, and a compiler tray 15.
a stapler 17 that staples a predetermined portion of a bundle of sheets supplied to the paper stack, a conveyance roller 18 that conveys the sheets that are naturally dropped from the tray 15 when the gate 16 is opened, and a conveyance roller 1.
A guide mechanism 19 that guides the paper (or copy set) discharged directly from the guide mechanism 1 or from the transport roller 18, an output tray 20 that receives and places the paper discharged from the guide mechanism 19, and a paper size, Based on the information and data from the sensor and the console 21, the console 21 is equipped with buttons for setting the number of copies, setting the reduction ratio, setting the mode, etc., and a display for displaying the operating status, number of copies, etc. A control section 22 outputs control commands that control the finisher 10 and the copying machine main body 1; and a control section 22 that drives each drive system in the copying machine main body 1 based on the control commands output from the control section 22. , a motor 24 for driving each conveyance roller in the finisher 10, a drive section 23 for driving the selector 12, gate 16, and stapler 17.

The control unit 22 includes an input interface 22b that inputs information and data from various sensors, the paper sensor 13, and the console 21, and sends the digitized signal to the bus 22a at a predetermined timing.
and a ROM 22c storing a program for copying and stapling.
A CPU 22d executes various processes according to the programs in the ROM 22c, and temporarily stores processing results by the CPU 22d and external data.
It is composed of a RAM 22e and an output interface 22f that outputs control commands generated as a result of processing by the CPU 22d to the drive section 23 at a predetermined timing and format.

In the above configuration, originals are sequentially fed to the platen by an automatic document feeding device (not shown), and copy paper is fed from a paper feed cassette (not shown) in synchronization with the progress of scanning and development. Copying is performed accordingly. After copying, the paper is transferred to the transport roller 2 via the transport path.
reaches the finisher 1 by the roller 2.
Sent to 0. The supplied paper is sent to the latter stage by the transport roller 11, but when the staple mode is selected by the console 21, the paper is sent to the transport roller 14 side because the selector 12 is located at the lower side. It will be done. Also, when the staple mode is off, selector 1
2 is located on the upper side, and the paper from the conveyance roller 11 is sent out to the guide mechanism 19.
The sheets naturally fall onto the discharge tray 20 from the conveyance roller provided at the exit of the tray 20, and are sequentially accommodated therein.

The paper fed into the conveyance roller 14 is sequentially fed into the compiler tray 15 from the leading edge of the paper, and as the tail end is paid out, it slides down on the tray 15, and the tail end is locked in the gate 16. It will be placed in The paper sensor 13 detects that the number of original sheets has passed, and the control unit 22 issues a command to the drive unit 23 to operate the stapler 17.
Output to. The stapler 1 is driven by the drive unit 23.
When the plunger 7 is driven and stapling is performed normally, the control section 22 outputs a command to open the gate 16 to the drive section 23, and the motor 24 that drives the guide mechanism 19 is driven. Under this control, the gate 16 rotates clockwise, and the stapled copy set is sent out from the compiler tray 15 to the guide mechanism 19, and conveyed by the mechanism 19 to the discharge tray 20.

By the way, an interrupt occurs for some reason just before the stapler 17 is driven after the staple mode is set (for example, when the stop button is pressed,
If an interrupt button or the like is operated), the control unit 22 cancels the staple mode and executes control to stop all drive mechanisms of the finisher 10. Therefore, in such a state, the operator should press the all clear button (a button that returns all the settings set prior to copying to the initial state and sets the same state as immediately after the power is turned on) provided on the console 21. (For example, if the above-mentioned stop button and all clear button are used together, only one operation is required).
It is determined whether or not the stapling mode is released, and the gate 16,
The motor 24 and conveyance roller 18 are turned on for a certain period of time. As a result, the unbound sheets in the compiler tray 15 are transferred to the output tray 2 via the gate mechanism 19.
sent out to 0.

〔Effect of the invention〕

As explained above, according to the copying machine equipped with the finisher of the present invention, when the all clear button (mode reset button) is operated in the staple mode immediately before stapling, the paper in the compiler tray is ejected to the output tray. Because of that,
Since the paper can be ejected without manual intervention, extra effort can be saved, and there is no risk of touching the inside, which can also prevent danger.
