Abstract

PURPOSE:To prevent generation of a binding failure, by operating a stapler before exceeding the binding capacity by the stapler. CONSTITUTION:When the binding capacity M is, for instance, 30 sheets, and the set number of sheets N by an operator is, for instance, 70 sheets, when a counter has counted 30 sheets, a stapler 9 is operated, copies of 30 sheets are bound, and subsequently, copies of 30 sheets are bound in the same way, and in he end, the residual copies of 10 sheets are bound. In this case, two copies of 30-sheet binding, and one copy of 10-sheet binding are obtained. In this way, in case the set number of sheets N of the copy exceeds the binding capacity M (N>M), the stapler 9 is operated before the number of sheets of the copy stacked in a tray exceeds M, and by repeating it, the copies are divided and bount at every operation of the stapler 9, and no binding failure is generated.

Description

DETAILED DESCRIPTION OF THE INVENTION Aid 4/1 The present invention relates to a copy binding method in an automatic binding device.

Some finishers attached to copying machines and the like are equipped with an automatic binding device. This automatic binding device operates a stapler to drive staples into a predetermined number of copies stacked on a tray, thereby binding the copies. In such an automatic binding device, if the stapler is used to staple the copies when the number of copies exceeds the binding capacity, binding defects will occur and subsequent handling will be extremely troublesome. In the past.

The situation was such that no measures were taken to address these issues.

An object of the present invention is to divide and bind copies when the number of copies exceeds the binding capacity.

The purpose is to prevent the above-mentioned binding failure from occurring.

In order to achieve the above object, the present invention provides an automatic binding device that binds a predetermined number of copies by stacking copies on a tray, arranging them, and driving a stapler to staple a predetermined number of copies. The number of copies to be stacked is counted by a counter, and assuming that the stapling capacity of the stapler is M and the number of copies set by the operator is N, if N>M, the number counted by the counter exceeds M. This method is characterized in that the stapler is first operated and then this is repeated, thereby dividing and binding the copies each time the stapler is operated.

The present invention will be explained below with reference to illustrated embodiments.

FIG. 1 shows a schematic configuration of a buini rasher embodying the present invention.

The finisher is attached to a copying machine or the like, and the copy paper P that has been copied is discharged from a pair of discharge rollers 1 of the copying machine and enters the finisher 2 as a copy. At this time, the sensor 3 detects each incoming copy P, and in conjunction with this detection, the number of copies is counted by a counter to be described later.

The switching claw indicated by numeral 10 has been switched to the imaginary line position,
The copy P is conveyed by the pair of conveying rollers 4 and guided by the switching pawl thereof toward the pair of conveying rollers 5. The copies that have passed through the transport roller pair 5 fall onto the tray 7 from the transport roller pair 6, and are stacked on the tray 7 as the copies are sequentially fed. Then, the copy on tray 7 hits gate 8,
Aligned in a predetermined direction.

The finisher 2 is equipped with an automatic binding device including the above-mentioned tray 7, gate 8, and stapler 9 that essentially performs binding.

As is already known, the stapler 9 automatically staples a predetermined number of copies to bind the copies.

When the number of copies that hit gate 8 reaches a certain number,
The stapler 9 operates, staples are driven, and the copies are bound. When this is completed, the gate 8 is opened and the bound copies are discharged onto the discharge tray 13 via conveyance rollers 11 and 12.

Here, the binding capacity of the stapler 9 is assumed to be M sheets. Further, the number of copies that the operator intends to make from now on, that is, the set number of copies, is set to N.

As shown in FIG. 2, the copy detection signal from the sensor 3 is input to a counter, where the number of copies is counted, and this count signal is input to the CPU. This CPU then uses the gate 8 and stapler 9 via the driver.
The drive is controlled as described below.

Here, let us assume that the binding capacity M is 30 sheets and the number of sheets N set by the operator is 25 sheets.

In the flowchart shown in FIG. 3, while the counter is counting up, the count number C is 25 (N
), the stapler 9 and gate 8 operate, and the stapler 9 staples 25 copies. This is the case with the following number of sheets.

Next, if the binding capacity M is also 30 sheets, and the number N set by the operator is 70 sheets, when the counter counts 30 sheets, which is the same number as the binding ability (C=M), the stapler 9 is activated, 30
First, 30 copies are bound in the same way, and finally the remaining 10 copies are bound.

In this case, two 30-sheet bound copies and one 10-sheet bound copy will be obtained.

As described above, the feature of the copy binding method of the present invention is that when the number of copies set by the operator N exceeds the binding capacity M (N>M), the number of copies stacked on the tray 7 exceeds M. First, the stapler 9 is activated, and this is repeated thereafter, so that the copies are divided and stapled each time the stapler is activated.

As described above, in the present invention, the stapler is activated before the stapling capacity of the stapler is exceeded, so that no binding defects occur and the trouble of rebinding copies is eliminated. Can be done.

Claims (1)

[Claims] By stacking the copies on the tray and aligning them, operate the stapler to staple the copies.
In an automatic binding device that staples a predetermined number of copies, a counter counts the number of copies stacked on the tray, and assuming that the stapling capacity of the stapler is M and the number of copies set by the operator is N, N>M.
If so, the copy binding method is characterized in that the stapler is operated before the count number by the counter exceeds M, and thereafter, this is repeated, thereby dividing and binding the copies each time the stapler is operated. .
