Abstract

PURPOSE:To supply a following copy group to a staple without providing any waiting time behind a preceding copy group by outputting a signal for stapling when a final copy is discharged from a copying machine and supplied to a bookbinding device. CONSTITUTION:This device is provided with a counter which counts copies discharged from the copying machine 2000 and a counter which counts copies stacked at the intermediate stack part 22 of the bookbinding device. Then when the control CPU in the copying machine 20 commands the number of copies discharged from the copying machine 2000 and the passage of the final copy is checked, a stapler 23 is put in stapling operation by condition that the counted values of the two counters are equal to each other. Therefore, when successive copy groups are stapled, and waiting time need not be provided by interrupting the stapling operation for the following copy group and the efficiency of the bookbinding operation is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a bookbinding apparatus, and more particularly to a bookbinding apparatus that stacks copies discharged from a copying machine and binds them with a stapler such as Stapler (trade name).

(Prior Art) As is well known, when a set of manuscripts consisting of multiple sheets is copied using a copying machine, the resulting copy (hereinafter referred to as "copy") is produced.

Copies may be manually bound at one corner or at two or three locations on one side using a stapler (trade name).

By the way, recently, as part of office automation, recycled automatic document feeding bags [(RADF)
is being used, in this case.

- A set of originals is automatically fed onto the contact glass of the copying machine, one exposure is performed for each original feeding, the M originals are fed through the required number of times, and the copy is made. A series of copies, so-called copies, are continuously ejected from the machine in the required number. Therefore, if you connect a simple bookbinding machine that can automatically staple each set of copies that are continuously ejected to the copy output port of the copying machine, the binding process will not require any manual effort. This is convenient because it speeds up the work.

Therefore, as an example of such a bookbinding apparatus, there is an apparatus shown in FIG. 4.

That is, this bookbinding bag [100 is disposed adjacent to the copying machine main body 20G so that the receiving port 101 is connected to the copy outlet 201 of the copying machine main body 200.

Inside this device 100, a copy receiving port 10 is provided.
Guides 2 and 3 are provided following guides 2 and 3, receiving rollers 4 and 5 are provided along the guides 2 and 3, and a tray 6 that serves as an intermediate stack section extending forward and downward in the copy ejection direction is provided. A copy receiver 11 is provided in front of the tray 6 in the ejection direction.

Further, a pair of side guide plates 7 and 8 are provided on the sides of the tray 6 and are movable in a direction perpendicular to the moving direction of copying.

are provided, and staplers 10 are fixed near both sides of the end stopper 9.

In such a bookbinding device 100, the copying machine main body 20
The copies introduced in page order from 0 to the receiving port 101 are as follows:
Guided by the guides 2 and 3, the paper advances on the tray 6, and is stapled by the stapler 10 with the side edges and tips aligned by the side guide plate 7 and the end stopper 9 (for example, Japanese Patent Laid-Open No. 60-180897
Publication No.).

By the way, in such a bookbinding device, a set of copies ejected from the copying machine is all stored on the tray 6, and then stapled in response to a staple signal from the copying machine, and the copy reception is carried out at the input 11. However, the staple signal from the copying machine is not output until the final copy is placed on tray 6, and stapling is therefore not performed. Until the copy is stored on tray 6, another subsequent one
The set of copies cannot be ejected to the bookbinding device. Therefore, in such a bookbinding apparatus, when stapling successive copy groups, the stabilization operation of the subsequent copy group is interrupted until the stapling of the preceding copy group is completed between each copy group. However, there was a problem in that it was necessary to provide a waiting time, and the efficiency of bookbinding work could not be improved.

(Objective) In view of the problems of conventional bookbinding devices, an object of the present invention is to staple a subsequent group of copies without creating a waiting time between the preceding group of copies when stapling successive groups of copies. The purpose of this invention is to obtain a bookbinding device that is capable of binding books.

(Structure) In order to achieve this object, the present invention includes a counter that counts the number of copies ejected from a copying machine, and! 1. A counter is provided in the intermediate stack section of this device to count the number of copies to be stacked, and stabilization work is performed by determining when the numbers of the counters match and a stapling signal from the copying machine. It is a suggestion of what to do.

(Effects) As is clear from the above description, according to one aspect of the present invention, a signal for stapling is outputted at the time when the final copy is ejected from the copying machine and introduced into the bookbinding device, thereby making it possible to copy the copy. This eliminates the waste of waiting until the final copy ejected from the machine reaches the intermediate stack section, the so-called stapling position, before outputting the stapling signal.

Therefore, since it is possible to introduce the subsequent copy group into the bookbinding device in succession to the preceding copy group, the binding of the subsequent copy group can be performed until the copies reach the stapling position between each copy group. There is no need to interrupt the introduction into the apparatus, and as a result, stapling work can be performed efficiently and without slowing down the speed.
