After finishing it, the clutch 16 is turned on to rotate the eccentric cam 15 by half and the bin is returned to the former position and a motor for shifting a stapler is energized to shift the stapler 21 in the vertical direction and when it detects the correspondence of a bin 3 corresponding to it, it stops and starts a stapler driving work. In this way, the device can be simplified.

The paper entry sensor 53 inputs a paper detection signal to a timer means 59 which generates an output signal to energize each deflection solenoid 34 at a predetermined timing.

It is also used to obtain paper count information for determining the paper output destination.

Further, the CPU 56 of the main body of the copying machine, the sorter, and the automatic document feeder rn (hereinafter referred to as ADF) are connected online, so that information can be exchanged at all times.

The present invention having the above configuration operates as follows,
This will be explained with reference to FIG.

When the power is turned on, an electrical initial setting such as setting the storage location of each data in the RAM 57 is performed, and then the stapler 21 moves to the stapler driving position of the first bin.

Further, the operator loads desired originals onto the ADF, and inputs the number of copies for each original as a number using operation buttons (not shown) on the copying machine, and the input information is stored in the RAM.
57. Here, when the stapling mode is designated, a stapling flag is set in the RAM 57. When the operator inputs a copy start signal, copying is started and the ADF and sorter are put into operation.

The paper ejected from the copying machine main body to the sorter is detected by the paper incoming sensor 53, and this detection signal is stored as a count number in the counter in the RAM 57, and is also stored in the counter in the RAM 57.
After receiving the detection signal, U 56 drives a timer 59 to energize the bin deflection pawl solenoid 34 corresponding to the count number at a predetermined timing.

When the deflection pawl solenoid 34 corresponding to the count is energized, the deflection pawl 32 enters the paper conveyance path 51 and guides the paper to the corresponding bin 3.

That is, if the count is 1, the deflection pawl solenoid 34 for the first bin is energized.

When the paper is discharged into the bin 3, the photoelectric paper end detection sensor 52 detects this, deenergizes the deflection claw solenoid 34, and the deflection claw 32 returns to its original position.

In this way, each deflection claw 32 corresponding to each bin is sequentially controlled according to the count contents, and the second and subsequent sheets are also distributed to predetermined bins. Then, the CPU 56 clears the count stored in the counter when the paper count detected by the paper input sensor 53 is equal to the number set by the operator. Further, the ADF ejects the paper on the contact glass based on the signal and feeds the next original. Further, the same operation as described above is repeated for discharging the second and subsequent documents, and the sheets are distributed to each bin.

This process continues until there are no more manuscripts left. That is, a document end sensor 51 is attached to the document table of the ADF, and when there is no document on the document table, a detection signal is sent to the CPU.
Send to 56. Upon receiving this signal, the CPU 56 outputs a command to connect the bin moving motor 17 and the 172-rotation clutch 16 for stapling when the paper on which the final original has been copied is discharged into the first bin. That is, f! when the document end sensor detects that the document is not on the paper feed table.
The tCPU 56 determines the presence or absence of a stapling flag. If the flag is set, a timer element is provided that measures a predetermined period of time based on the counter clear signal generated when the original has been copied for the set number of copies, and the output drives the bin moving motor 17 to perform the stapling operation. Do it like this. The timer is connected to the first one from the photoelectric paper input sensor 53.
If the time required for conveyance to the bin is measured, there will be no chance of accidentally stapling before all the sheets have been ejected.

Note that the motor 17 is driven by a copy start command.

In FIG. 2, the connected 1/2 rotation clutch 16 rotates the eccentric cam 15 by half a turn, presses the large diameter portion of the eccentric cam 15 against the roller 14, and swings the bin 3 by moving the lever 8. A pair of photoelectric sensors 55 are attached near the eccentric cam 15 with the eccentric cam 15 in between.
It is designed to output when it is brought close to .

When the photoelectric sensor 55 outputs an output, this output status signal is sent to the CPU 56, and the CPU 56 sends a stapling command to the stapler 21.

The stapler 21 is provided with a stapling detection sensor 54, which detects the completion of the stapling operation.

Further, the detection signal 5 is sent to and stored in the RAM 57 as stapling count information. Furthermore, this information is sent to the CPU 56, and the CI'tJ5G operates the motor 17 and l/l based on the information to return the bin to its original position.
A command to connect the two-rotation clutch 16 is issued. Therefore, the 1/2 rotation clutch 16 is engaged, and the eccentric cam 15 rotates, and the roller 14 and the small diameter portion of the cam oppose each other, so that the bin 3 returns to its original position. At that time, a second photoelectric sensor 55' sandwiching the eccentric cam 15 is provided, and the small diameter portion of the cam is connected to the roller 14.
Since the output of the photoelectric sensor 55' is arranged to be output when the photoelectric sensor 55' is opposed to the
can be conveyed to. Then, the CPU 56 compares "the number of times staples have been driven" stored in the RAM with "the number of copies to be made for each document, that is, the number of copies placed", and if they are different, energizes the stapler moving motor 42 and moves the stapler to the next detection hole. 44 until the position sensor 43 detects the stapler movement motor 42.
is driven and the staple moves.

The CPU 56 outputs a signal to reduce the power of the motor 42 when the position sensor 43 detects the detection hole 44 corresponding to the bin to be stapled. At the same time, the staple 21 is stopped at a predetermined position by a braking means (not shown), such as applying reverse braking to a motor. Further, vertical movement of the stapler 21 due to impact during the staple driving operation is prevented by a worm gear 41 having a mechanically irreversible characteristic.

From now on, work on the second and third bins in the same way as the first bin, and after each stapling is completed, the "Number of staples" and "Number of staples"
The number of copies to be made for each document is compared, and the staple movement and driving operations are performed until the numbers of copies are the same.

If the comparison results in a match, all the operations are completed and the stapler returns to the stapler driving position of the first bin and returns to the standby state.

As described above, the present invention has the feature that the apparatus is simplified because the work for each bin of the sorter is executed by moving one stabler apparatus up and down.
