In the above steps A1 and A2, the receiving unit 1
When the worker loads the paper sheet 7 between the pressing plate 4 and the step portion 3 at the standby position in the opening direction, the paper sheet detection sensor 31
Outputs a detection signal when the optical path 31c is blocked by the paper sheet 7, thereby driving the opening / closing drive unit 30 to move the pressing plate 4 in the closing direction. In step A3 above,
On the way of moving the pressing plate 4 in the closing direction by driving the opening / closing drive unit 30 (before the pressing plate 4 presses the loaded paper sheets 7).
When the output of the detection signal from the paper sheet detection sensor 31 is stopped by removing the loaded paper sheet 7 in step A1,
Proceeding to step 4, a predetermined process (described later) is performed.

In steps A4 and A5, when the detection plate 28 is detected by the closing limit position detection sensor 33 by driving the opening / closing drive section 30, the loaded paper sheets 7 are detected.
If the pressing plate 4 is pressed by the urging force of the urging means 19, the driving of the opening / closing drive unit 30 is stopped and the detection plate 28 is not detected by the closing limit position detection sensor 33, the pressing plate 4 is still on. Assuming that 4 does not press the paper sheet 7,
The process returns to step A3 and the process is repeated. Step A above
In Nos. 14 to A19, when the paper sheet detection sensor 31 stops outputting the detection signal after the pressing plate 4 is driven in the closing direction by the opening / closing drive unit 30, the paper sheet 7 has been removed. Turn on the timer to start timing. And
If the paper sheet detection sensor 31 outputs the detection signal within the predetermined time, it means that the paper sheet 7 has been reloaded, so the timer is turned off, the process proceeds to step A2, and the opening / closing drive unit 30 operates. When the pressing plate 4 is driven in the closing direction and the paper sheet detection sensor 31 does not output the detection signal even after the lapse of a predetermined time, the timer is turned off and the process proceeds to step 10 to open and close the pressing plate 4 by the opening / closing drive unit 30. Drive in the open direction.

In steps A6 and A7, when a feeding start switch (not shown) is manually pressed, the feeding driving unit 15 is driven to rotate the feeding roller 12 and the kick roller 11 which is interlocked with the feeding roller 12 and the paper sheet. The pieces 7 are sequentially separated one by one from the side in contact with the kick roller 11 and fed into the apparatus main body 2. In steps A8 and A9, when the paper sheet detection sensor 31 no longer detects the paper sheet 7 during the feeding operation, the feeding drive unit 15 is stopped after a predetermined time has elapsed. Here, the predetermined time period corresponds to a conveyance time period from when the paper sheet 7 is no longer detected by the paper sheet detection sensor 31 until it is completely taken into the apparatus main body 2 and reaches a predetermined storage position. The conveyance of the paper sheet 7 is not stopped during the feeding conveyance.

In step A10, the feeding drive unit 15
After a certain period of time has elapsed since the stop, the opening / closing drive unit 30 is driven to position the pressing plate 4 at the standby position in the opening direction in preparation for loading the paper sheets 7. Step A11 to above
At A13, the pressing plate 4 is driven in the opening direction, and the detection plate 2
If 8 is detected by the open limit position detection sensor 34,
Since the pressing plate 4 has reached the standby position in the opening direction, the driving of the opening / closing drive unit 30 is stopped and the movement of the pressing plate 4 is stopped.
Further, while the pressing plate 4 is moving in the opening direction (before reaching the standby position in the opening direction), the paper sheet 7 is loaded, and the paper sheet detection sensor 31
If the detection signal is output by, the process returns to step A2 to move the pressing plate 4 in the closing direction.

As described above, according to the paper sheet processing apparatus of the first embodiment, the output of the detection signal from the paper sheet detection sensor 31 is stopped when the paper sheet 7 is no longer present in the receiving section 1, and as a result,
The control unit 36 drives the opening / closing drive unit 30 to move the pressing plate 4 in the opening direction and position it in the standby position. When the paper sheet 7 is loaded in the receiving unit 1, the paper sheet detection sensor 31
A detection signal is output from the control unit 36.
The opening / closing drive unit 30 is driven to move the pressing plate 4 in the closing direction. Therefore, when there is no paper sheet 7, the pressing plate 4
Is located at the standby position in the opening direction and the receiving unit 1 is ready to load the paper sheet 7 as it is. Therefore, for example, when loading the paper sheet 7 with both hands held, It is not necessary to once place the paper sheet 7 at another place in order to open the pressing plate 4. Therefore, the processing operation at the time of loading the paper sheet 7 is reduced, and the processing time can be shortened.

Further, when the paper sheet 7 is taken out and the output of the detection signal from the paper sheet detection sensor 31 is stopped while the paper sheet is loaded and the pressing plate 4 is moving in the closing direction by the opening / closing drive unit 30. The pressing plate 4 is stopped, and if the paper sheet 7 is reloaded again before a predetermined time elapses in this state, the pressing plate 4 will automatically move in the closing direction from the position at that time. It will be. Therefore, when the paper sheets 7 are reloaded, the pressing plate 4 moves in the closing direction from the position where the paper sheets 7 have been once moved, so that the time to press the paper sheets 7 can be shortened.

Further, when the paper sheet 7 is pulled out and the output of the detection signal from the paper sheet detection sensor 31 is stopped during the movement of the pressing plate 4 in the closing direction by the opening / closing drive unit 30 during the paper sheet loading. The pressing plate 4 is stopped, and when a predetermined time elapses in this state, the pressing plate 4 is automatically moved to the standby position in the opening direction. Therefore, if the sheets 7 are not reloaded after waiting for a predetermined time, the pressing plate 4 is automatically moved to the standby position in the opening direction.

Next, a paper sheet processing apparatus according to a second embodiment of the present invention will be described below with reference to FIGS. 4 to 6 focusing on differences from the first embodiment. The same parts as those in the first embodiment are designated by the same reference numerals and the description thereof is omitted. In the second embodiment, the guide block 17 is directly fixed to the upper side portion 25a of the endless belt 25, whereby the pressing plate 4 is directly opened / closed by the forward / reverse driving of the opening / closing driving unit 30. .

Further, the kick roller 11 is the feeding roller 12
Is rotatably supported on the other side of the support member 38, one side of which is swingably supported by the shaft portion of the. The support member 38 is
The kicking roller 1 is biased in the clockwise direction in FIG. 4 by a biasing means such as a tension coil spring (not shown).
A part of the peripheral surface of No. 1 projects from the facing surface 9 of the step portion 3 by a predetermined amount and abuts on a stopper (not shown) (this position is referred to as a swing limit position). Further, the support member 3 at the swing limit position
A rocking limit position detection sensor 39, which detects the proximity of the upper end portion in this state and outputs a detection signal, is provided at the upper end portion of 8 supported by a frame (not shown). The detection sensor 39, as shown in FIG.
It is connected to the. Note that when the support member 38 reaches a position where it is not detected for the first time from the position detected by the swing limit position detection sensor 39 (the state shown in FIG. 4), the kick roller 11 is optimal for kicking the paper sheet 7. In this state, the projecting member 4 is protruded from the facing surface 9 in the direction of the pressing plate 4.

The control contents of the control unit 36 of the second embodiment will be described below with reference to the flow chart shown in FIG. The control content of the control unit 36 of the second embodiment differs from the first embodiment in that step A4 is changed to the following step B4, and the following steps B20 to B23 are inserted between step A7 and step A8. Furthermore, the difference is that the destination at the time of YES determination in step A8 is step B20, and the other points are the same as in the first embodiment.

[Step B4] It is determined whether or not a detection signal is output from the swing limit position detection sensor 39. If it is output, the process proceeds to step A3. If not, the process proceeds to step A5. move on. When the paper sheet detection sensor 31 detects the paper sheet 7 in the receiving section 1 in step A3 and the swing limit position detection sensor 39 detects the support member 38 in step B4, Since the pressing plate 4 is in a state in which the kick roller 11 is not being pressed via the paper sheet 7 (that is, the movement in the closing direction is insufficient), the process proceeds to step A3 to maintain the closing direction drive. Then, when the pressing plate 4 is moved in the closing direction to press the loaded paper sheet 7 and press the kick roller 11 via the paper sheet 7, the supporting member 38 supporting the kick roller 11 is formed. If the rocking limit position detection sensor 39 no longer detects the support member 38 due to the rocking in the counterclockwise direction, the rocking limit position detection sensor 39 no longer outputs a detection signal. The control unit 36 controls the opening / closing drive unit 30.
Drive is stopped and the pressing plate 4 is stopped. At this time, the pressing force of the kick roller 11 and the pressing plate 4 against the paper sheet 7 by the urging force of the urging means (not shown) introduced into the support member 38 is optimum for kicking the paper sheet 7. It is set so that the pressing force is high.

[Step B20] It is determined whether or not a detection signal is output from the swing limit position detection sensor 39,
If it is output, the process proceeds to step B21, and if not, the process proceeds to step A8. [Step B21] A drive signal is output to the opening / closing drive unit 30 to drive the endless belt 25 so that the upper side portion 25a of the endless belt 25 travels in the direction of approaching the step portion 3, and the process proceeds to step B22. In the second embodiment, this causes the guide block 17 and the pressing plate 4 to move in the closing direction.

[Step B22] It is determined whether or not a detection signal is output from the swing limit position detection sensor 39,
If it is output, this step B22 is repeated, and if not, the process proceeds to step B23. [Step B23] The output of the drive signal to the opening / closing drive unit 30 is stopped, the drive of the endless belt 25 is stopped, and the process proceeds to Step A8.

In steps B20 to B23, the kick roller 11 and the feeding rollers 12 and 13 are used to move the paper sheet 7.
When the number of sheets 7 decreases, the support member 38 swings clockwise in FIG. 4, and the swing limit position detection sensor 39 detects the support member 38 and outputs a detection signal.
As a result, the control unit 36 drives the opening / closing drive unit 30 to move the pressing plate 4 in the closing direction until the swing limit position detection sensor 39 no longer outputs a detection signal. By repeating such a process, the pressing plate 4 is gradually moved in the closing direction according to the reduction of the amount of the paper sheet 7, whereby the pressing plate 4 always presses the paper sheet 7 with the optimum pressing force. be able to.

[0042]

According to the paper sheet processing apparatus of the first aspect of the present invention, when there are no more paper sheets in the receiving section, the output of the detection signal from the paper sheet detection sensor is stopped, whereby The control means drives the opening / closing drive means to move the pressing member in the opening direction and position it at the standby position. Then, when a paper sheet is loaded in the receiving section, a detection signal is output from the paper sheet detection sensor, whereby the control means drives the opening / closing drive means to move the pressing member in the closing direction. Therefore, when there is no paper sheet, the pressing member is located at the standby position in the opening direction and the receiving section is ready to load the paper sheet. For example, when holding the paper sheet with both hands, Even when the paper sheet is loaded, it is not necessary to once place the paper sheet in another place to open the pressing member. Therefore, the processing operation at the time of loading paper sheets is reduced,
The processing time can be shortened.

According to the paper sheet processing apparatus of the second aspect of the present invention, while the opening / closing drive means is moving the pressing member in the closing direction, the paper sheet is taken out and the detection signal is output from the paper sheet detection sensor. If the sheet is stopped, the pressing member is stopped.If the sheets are reloaded before the predetermined time elapses in this state, the pressing member will automatically move from the position at that time to the closing direction. Will move. Therefore, at the time of reloading the above-mentioned paper sheets, the pressing member moves in the closing direction from the position once moved, so that the time until the paper sheets are pressed can be shortened.

According to the paper sheet processing apparatus of the third aspect of the present invention, while the opening / closing drive means is moving the pressing member in the closing direction, the paper sheet is taken out and the detection signal is output from the paper sheet detection sensor. When the pressing is stopped, the pressing member is stopped, and when a predetermined time elapses in this state, the pressing member is automatically moved to the standby position in the opening direction. Therefore, if there is no reloading of paper sheets even after waiting for a predetermined time, the pressing member is automatically moved to the standby position in the opening direction.
