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 ejected from a copying machine and binds them with a stapler (trade name) or the like.

(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.

In some cases, a copy (referred to as a copy) is manually stapled at one corner or at 2.3 corners of a piece using a stapler such as a stapler (trade name).

Recently, recycling-type automatic document feeders (RADFs) have been used as part of office automation, and in this case, the - set of originals is automatically fed onto the contact glass of a copying machine. One exposure is performed for each original feeding, and the original is fed by circulating the required number of times, and a series of copies, so-called, are produced from the copying machine.
The required number of copies are continuously ejected. Therefore, if you connect a simple bookbinding machine that can automatically staple each set of copies that are output continuously to the copy output port of the copying machine, the bookbinding work will not require any manual effort. The bookbinding operation is speeded up and convenient.6Therefore, as an example of such a bookbinding apparatus, there is an apparatus shown in FIG. 12.

That is, the bookbinding apparatus 100 is disposed adjacent to the copying machine main body 200 such that the receiving port 101 is connected to the copy output port 201 of the copying machine main body 200.

Inside this device 100, there is a copy receiving port 101.
Following the guides 2 and 3 are provided, along with the guides 2 and 3 receiving rollers 4 and 5.

A tray 6 is provided which is tilted forward in the copy ejection direction.

Further, a pair of side guide plates 7.8 are provided on the sides of the tray 6 and are movable in a direction perpendicular to the moving direction of copying. An end stopper 9 is provided that enters onto the tray 6 only when stapling copies, 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 Application No. 180897/1989
Publication No.).

By the way, in the bookbinding apparatus having the above-described structure, the stapler 10 is fixedly provided within the apparatus.

- When binding a set of copies, it is necessary to move the copies to the position of the stapler 10, and as a result,
The stapling position is limited regardless of the size of the copy, the direction of travel, etc.

Furthermore, in the case of small-size copying, there is a risk that sufficient movement to the corresponding position with the stapler may not be possible or that alignment may be insufficient. This has a greater effect depending on whether the copy is ejected based on the center or edge.

(Purpose) The purpose of the present invention is to make copies ejected from a copying machine, regardless of whether the copy is ejected from the center or from the edge.
To obtain a bookbinding device capable of stapling at any location or at a plurality of locations.

Note that the switch S6 is located in front of the stapler 23 in the moving direction of the conveyor belt 24 and corresponds to the piece member 24a.

This switch S6 is operated by the piece member 24a,
During this operation, the conveyor belt 24 is stopped and placed at the starting position.

On the other hand, guide fences 34, which will be described later, are arranged on both sides of the tray 22, which is the intermediate stack section described above.

That is, as shown in the second figure, the stapler 23 is provided corresponding to the leading edge of the copy, and the guide fences 34 are provided corresponding to the edges of the copy.

The stapler 23 is configured to be able to move in the width direction of the copy in conjunction with a stepping motor (not shown), and the guide fence 34 is also movable in the width direction of the copy in conjunction with a stepping motor (not shown). There is.

The stapler 23 and the guide fence 34 are each configured as a pair, but they can move mutually or independently.

The above-mentioned stepping motor is driven by a driver 35 connected to a microcomputer 33 forming a control section of the bookbinding bag, as shown in the third figure.

That is, the microcomputer 33 is the copying machine 1000.
It is connected to the control CPυ of 1, and is also connected to each of the above-mentioned switches via an interface (not shown).

Data is serially transferred to the microcomputer 33 from the control CPU of the copying machine 2000, and the contents of the data include the staple position, number of staples, and copy size for copies ejected from the copying machine 2000. and ejection status (center reference, end face reference).

Microcomputer 3 to which such data was transferred
3 drives the stepping motor in accordance with the data to make the stapler 23 and guide fence 34 correspond to copying.

Since this embodiment has the above-described structure, the operation will be explained below using the flowchart shown in FIG. 7.8.

That is, in FIG. 7, when the bookbinding apparatus 1ooo is powered on, it is determined whether the pair of guide fences 34 are at the home position shown by the two-dot chain line in FIG. .

This is confirmed by determining whether the pair of staplers 23 are at the home position indicated by the two-dot chain line in FIG.

In this embodiment, the operation is performed based on a command from the control CPU of the copying machine 2000, and as shown in FIG. If you need to judge and punch,
The locking piece 29 is advanced into the conveyance path A, and the punch 2

In the case of a single copy, the copy that has passed through the conveyance path A is delivered to the copy receiver 18, and in the case of a group of copies, after confirming that the final copy has been stocked by the tray 22, It is stapled by the stapler 23. Thereafter, the copy is placed in the ejection position on the tray 22 by retracting the feeding member 30, is pushed and moved by the piece member 24a as the conveyor belt 24 moves, and is ejected to the copy receiver 32, and then 24 is placed in the starting position by actuating switch S6.

When the above-described copy requiring stapling is ejected from the copying machine 2000, the control CPU of the copying machine 2000
The microcomputer 33 operates by transferring the data regarding the copy by the microcomputer 33 .

That is, as shown in FIG. 5A, the microcomputer 33 checks whether the data from the control CPU of the copying machine 2000 is a central reference copy in step STI in FIG. The copy size is determined in step ST2.

Checking with Sr1, if it is now the A3 size, the stepping motor is driven to adjust the width of the guide fence 34 to that size.

A stepping motor is driven to adjust the position of the stapler 23 to the width of the stapler 23. In this case, the stapler 23 corresponds to the home position of the guide fence 34 in the embodiment. Then, it is checked in step ST4 whether the stapling position by the stapler 23 is fixed at one point on the left or right, and the stapler flag is set in step ST5. Sr1 is set to "1", the stapler 23 is operated, and as shown in FIG. 4(A),
Stapling is performed at the stapling position indicated by the symbol S in (B).

Also, if the staple position is not on the left or right,
It is determined that two-point fixing is required, and the stepping motor is driven to move the pair of staplers 23 to the center, thereby operating the staplers 23 to perform stapling as shown in FIG. 4(C).

On the other hand, even if the size is not A3, step ST
3, the stapling position is determined and set in the same manner (the contents of the flowchart indicated by reference numeral C in the figure are executed).

Further, as shown in FIG. 5B, when the data from the control CPU of the copying machine 2000 is based on the end face, the microcomputer 33 performs step 5TI in FIG.
The size of the copy is checked by O, 5 TII, and if it is now an A3 size, the Stella pin motor is driven to move one of the guide fence 34 and the stapler 23 in accordance with the size, as shown in FIG.

Then, as in the case of FIG. 9, after checking the stapling position, one or both of the staplers 23 is operated to perform stapling.

In this manner, the microcomputer 33 controls the operation of the guide fence 34 and the stapler 23 in accordance with the size and ejection state of copies ejected from the copying machine 2000, the staple position, and the number of staples.

Note that FIG. 11 is a timing chart showing the timing of activation of each switch, stapler, and members interposed in the conveyance path.

(Effects) As is clear from the above description, according to the present invention, copies ejected from a copying machine can be ejected without aligning the copies with the stapler, regardless of whether the copy is ejected from the center or from the edge. The staple position and number of staples can be easily set using the stapler.

Therefore, it is possible to perform stapling in a manner that is suitable for any kind of copying.
