It is determined whether the counter set in ep 605 has finished counting (step 5 step 606), and if the count has increased, the process proceeds to step 5 609, and if the count has not increased, the process proceeds to step 5 607. 5Lep 607 determines whether there is a paper discharge signal from the copying machine main body, and only if there is no paper ejection signal, it is determined that the sheet has completely come out from the copying machine main body, and the conveyance speed is maximized (Step 608), 5t.
Step 609 proceeds after step 608 is determined to be the point at which discharge control is performed, and the conveyance motor 21 is controlled to the sheet discharge speed of the copying machine main body. After that, set the counter to measure the discharge completion point 5 step 61
0), the operation ends when the counter increases (Ste
p6 1 1).

Next, the stable operation will be explained along the diagram tJIJ19.

First, in 5tcp701, the stapler swing motor 85 is turned on to move the stapler 17, and the stapler 17 is moved to the operating position 17a until both the stapler operating position sensor S7 and the stapler positioning sensor S6 are turned on. The swing motor 85 is driven. Next, the stapler motor 71 is driven to perform stapling. For stapling, drive the stapler motor 71, and after confirming that the stapler cam sensor SIO is turned off, turn off the stapler motor 71 until it is turned on, that is, after one rotation, and finish the stapler motor 71 of fir-J ( 5tep702). After that, until the stapler operating position sensor S7 turns off and the stapler positioning sensor S6 turns on, that is, until the stapler 17 or the retracted position 1
Drive the stapler swing motor 85 until the stapler moves to 17b (5tep703).

After that, it is determined whether or not all bins B... have been completed, and if they have not been completed, the bins are shifted by one (Step
705), 5step7 to do the next stapling
The stapling operation progresses to step 01, and when the stapling operation is completed, the stapling operation is completed.

In the embodiment described above, a case has been described in which the non-sort sheet stable button S13 is provided on the sorter I side, and thereby the binding operation is performed without sorting the sheets, but the present invention is not limited to this.

It may be by a signal from the main body of an image forming apparatus such as a copying machine. For example, if the mode setting means provided on the main body of the image forming bag is set to a mode in which the sheets are bound without being sorted, the signal may be sent from the main body of the image forming bag. Depending on the sent mode setting signal, the binding operation may be performed without sorting the sheets.

(g) As described in detail, according to the present invention, when the binding operation is performed without sorting sheets, the sheet distributing means is switched to the bin side even if the sheet is not sorted. For example, even in the case of a single copy, where sheets that are not classified or are ejected into a bin when the operating means is operated, and which conventionally cannot be bound or fixed, the binding means, etc. It is possible to bind and fasten sheets without changing the structure of the transmission members.
