In the present embodiment, 15a is used as the light emitting unit and 15b as the light receiving unit in the paper set sensor. On the contrary, 15a can be used as the light receiving unit 15b as the light emitting unit.

The attached figure 1a shows the initial stapling operation state of the stapler 1. When the sheet 17 is placed in the stapler 1, the sheet set sensor 15a, 15b causes the sheet to be removed. It is detected as set. At this time, the stapler (1) state is a state in which the staple sensor 14 is in the sensing groove 13 of the staple sensing plate 12 (in contrast to the sensing groove of the staple sensing plate 12 13) can also be used as a sensing protrusion).

1B is a diagram illustrating a stapling operation state of the stapler 1. When the staple switch 26 (not shown in FIG. 1A) is pressed in the state of FIG. The staple motor 11 rotates in the forward direction to move the staple head 16 downward in the direction of the set paper 17 to perform stapling. At this time, since the staple sensing plate 12 is coupled to rotate at the same time as the rotating shaft of the staple motor 11 at all times, the staple sensor 14 is the sensing groove 13 of the staple sensing plate 12 ) Out of state.

Even after the stapling is completed by placing the staple stitches on the sheets of paper 17 set through the staple head 16, the staple motor 11 continues to rotate in the forward rotation direction and is again used. By returning to the state of 1a, one cycle (1CYCLE) of the stapling operation is completed.

As described above, in the present invention, the driving force for the stapling operation is provided from the motor to perform the stapling operation, but under normal operation, to perform the stapling operation while rotating the staple motor 11 only in the forward rotation direction. do.

2 is a block diagram illustrating an exemplary embodiment of a control circuit of a stapling apparatus according to the present invention, in which FIG. 21 is a central control unit, 22 is a staple motor driver, 23 is a staple motor, and 24 is a staple. A sensor, 25 is a paper set detecting unit, 26 is a staple switch, and 27 is a staple jam display unit, respectively.

As shown in FIG. 2, the control circuit of the stapling apparatus according to the present invention includes a ROM, a RAM, and a CPU (Central Processing Unit), and controls the overall operation of the control circuit. And a staple motor driver 22 connected to the central controller 21, the staple motor driver 22 for providing power required for stapling operation, and the staple motor driver 22. A staple motor 23 capable of reversing, a staple sensor 24 connected to an output terminal of the central control unit 21 and detecting a groove 13 formed in the staple sensing plate 12; The output terminal is connected to the central control unit 21 and is connected to the paper set detecting unit 25 for checking whether the paper 17 is set in the stapler 1, and the central control unit 21. So that users can request stapling Is provided with a staple switch 26, and a staple jam (STAPLE JAM) display unit 27 are connected to the central control unit 21 and indicating to the user that the event of a jam.

3 is a flowchart illustrating an embodiment of a method for controlling a stapling apparatus according to the present invention.

Initially, the system is initialized (301), and it is checked whether or not the staple switch 26 is ON (302). If the staple switch 26 is not ON, it is repeatedly checked while waiting until it is ON (302), and if it is ON, the stapling subroutine of FIG. In step 303, the staple switch 26 is checked again.

4 is a STAPLING subroutine execution flow diagram of FIG. As described above, this is performed every time the staple switch 26 is turned on. In the stapling subroutine execution, first, a plurality of sheets of paper 17 are in the stapler 1. It is checked whether it is set (401). Thus, if the paper 17 is not set in the stapler 1, it returns immediately so as not to perform an unnecessary stapling operation, and if the paper 17 is set in the stapler 1, The staple motor 23 is turned ON in the electrostatic direction in the stapling direction (402), and the staple timer (set to a time that can sufficiently staple in the normal state) is started (403).

Then, the staple sensor 14 is checked to determine whether or not the staple is completed (404). If the staple operation is completed normally, the staple motor 23 is stopped (OFF) (405), Returns. On the other hand, if the staple operation is not completed (404), then it is checked whether the staple timer has timed out (406). If the set time of the staple timer has not been exceeded, it is again checked whether or not the staple is completed (404). If the set time of the staple timer has been exceeded, the set paper 17 sets the stapler capacity. It is regarded as jam caused by exceeding or bad staple needle condition, and so on, the STAPLE JAM subroutine of FIG. 5 described later is performed (407) and returned.

FIG. 5 is a STAPLE JAM subroutine execution flow diagram of FIG. 4. This is performed to process jams generated every time jam occurs during the execution of FIG. 4. In the STAPLE JAM subroutine execution, first, the staple motor 23 is turned OFF (501). At the same time, the jam flag is set so that the user can recognize the staple jam, and the jam flag is set (502), and the staple motor 23 is rotated in the reverse direction opposite to the stapling operation (503). .

As such, the reason for reversing the staple motor 23 is that the number of sheets of the set paper 17 has exceeded the stapler capacity or the staple needle is in poor condition, so that the staple needle is incompletely formed on the paper 17. Since it is lodged, it is very difficult to remove the paper at this time. Thus, the staple jam is generated by rotating the staple motor 23 in reverse direction so that the stapler 1 is driven in the reverse stapling direction in which a small load is applied. The paper and staple needles can be easily removed.

Then, by checking whether or not the staple reversal operation is completed (505), if it is determined that the operation to reverse the staple motor 23 is completed (505), the staple motor 23 is stopped (OFF) ( In step 508, it is checked whether the jam paper in the stapler 1 has been removed through the paper set sensors 15a, 15b, and 25 (509). If the jam paper is not removed (509), the process of determining whether to remove the paper 509 is repeatedly performed while waiting until the jam paper is removed. Thus, when the jam sheet is removed, the stapler 1 is regarded as in a normal state, and the staple jam display and flag are released (510), and then returned.

At this time, in order to detect an overload or the like during the reverse rotation operation of the staple motor 23, the staple reversal timer set to a predetermined time is started at the time of the reverse rotation of the staple motor 23 (503) ( 504). If the staple reversal operation is determined to be incomplete (505), if it is determined that the staple reversal operation is not completed, it is checked whether the staple reversal timer has timed out (505). Then, if the set time of the staple reversal timer has not exceeded, the reversal determination is repeatedly performed (505). If the set time is exceeded (506), only the staple motor 23 is stopped (507). Then return immediately, so that the staple jam is not released. In this case, the reverse rotation of the staple motor 23 is performed to release the staple jam. However, the staple reversal time has been exceeded, and the staple motor 23 may operate normally even if the staple motor 23 is out of power. Since it is in a state where it is impossible, it processes by the abnormal operation of the stapler 1.

Therefore, the present invention is constructed and operated as described above, so that the stapling operation is performed only when paper is set in the stapler, so that unnecessary staple needle consumption or stapling error does not occur, and staple jam When it occurs, the staple motor is rotated in reverse to make it easier to remove the jammed paper and needles.If the paper with the staple jam is not removed, no further action is taken to prevent further operation errors. This has the effect of remarkably improving the ease of use.
