Abstract

PURPOSE:To attain the function for stopping feeding out and taking in a paper sheet and discharging it at the time point when counting is ended, and also, to miniaturize the device by rotating forward a motor in the course of counting, transferring its rotation to each roller through a one-way clutch, rotating backward the motor at the time when counting is ended, and transferring its rotation to a roller of a carrying- out part through the one-way clutch. CONSTITUTION:When a motor 21 is rotating forward, its rotation is transferred to feeding-out rollers 14, 15 and a taking-in roller 8 through a first one-way clutch 34, and transferred to a roller 13 of a carrying-out part through a second one-way clutch 35. When the motor 21 is rotating backward, the transfer of its rotation is cut off in a first one-way clutch 34, and the rotation is transferred to the roller 13 of the carrying-out part through a third one-way clutch 37. Accordingly, in the case of executing batch counting, a function for rotating forward the motor 21 in the course of counting and rotating backward the motor 21 at the time when counting is ended, and executing continuously feeding-out, taking-in and carrying-out in the course of counting, and a function for executing carrying-out, while stopping sending-out and taking-in at the time when counting is ended can be attained by one motor 21. In such a way, the device can be made light in weight and small in size.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paper sheet counting device used for counting banknotes and the like.

[Prior Art] Batch counting type paper sheet counting devices that count and take out a set number of paper sheets, such as banknotes, are conventionally known. In general, this type of device includes a delivery section that sends out paper sheets stacked in a hopper one by one through a delivery row, a take-in roller that takes in the paper sheets sent out from the delivery section, and a guide member attached to the outer periphery of the delivery section. a take-in section that takes in sheets between the above-mentioned take-in section and sends them along the outer periphery of the take-in roller; a take-out section that catches paper sheets on the downstream side of the take-in section and carries them out to the take-out side while holding them between the take-out rollers, etc.; The apparatus includes a counting means for counting the number of sheets passing through the delivery section, and a drive mechanism for driving each of the rollers at a predetermined rotation speed ratio.

Then, in response to the number setting operation on the operation section, etc., the banknotes, etc. are continuously sent one by one from the sending section to the take-out section through the take-in section and the carry-out section, and the counting means counts the set number of bills. It is supposed to continue until it reaches .

In this type of device, when the set number of sheets is reached and counting is completed, the sending and taking of paper sheets from the hopper to the receiving section is stopped, but the sheets are left in the path from the receiving section to the unloading section. The final paper sheets counted need to be carried out. Therefore, although the delivery roller and the take-in roller are immediately stopped at the end of counting, the delivery section such as the delivery roller needs to be operated even after the counting is completed.

As a device having such a function, for example, Japanese Patent Application Laid-open No. 6
As shown in Publications No. 1 to 130145, a hopper, a delivery roller, etc. constitute a delivery section, a delivery drum (take-in roller), a guide, etc. constitute a take-in section, and the delivery drum rotates coaxially with the delivery drum. The unloading section is made up of an inertial drum freely disposed and a unloading roller (unloading roller) in close contact with the inertial drum, and some unloading rollers are configured to transmit rotation from a motor via a one-way clutch. According to this device, during counting, the delivery roller and the delivery drum are driven by a motor and rotate, and the rotation is also transmitted to the delivery roller, so that the delivery roller and the inertial drum rotate together.Then, when counting is finished, the delivery roller and the inertial drum rotate together. When the motor is stopped, the delivery roller and delivery drum are stopped, while the inertia drum and delivery roller continue to rotate due to the inertia of the inertia drum, thereby delivering the last sheet to be counted.

In addition, in this type of sheet counting device, after performing batch counting to count a set number of sheets, when repeating the process of taking out the counted sheets from the stacker and performing batch counting again, it is necessary to perform a start operation each time. Doing so requires complicated operations.

As a countermeasure for this point,
As shown in the publication, a stop mechanism consisting of an electromagnetic clutch mechanism is installed between the motor and the feeding roller that feeds paper sheets from the hopper. The above-mentioned stop mechanism stops the above-mentioned feeding roller while the motor continues to be driven so as to keep the banknotes in an operating state, and when the sensor detects that a banknote has been taken out from the stacker, the stop of the above-mentioned stop mechanism is released. , a device is known that automatically restarts batch counting processing.

[Problem to be solved by the invention]

According to the device disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 61-130145, since the inertial drum continues to rotate due to inertia at the end of counting, a considerable amount of f is applied to the inertial drum.
Iffl must be provided, which poses problems such as an increase in the weight of the entire device.

Further, according to the device disclosed in the above-mentioned Japanese Patent Publication No. 57-22282 for automating batch counting processing,
After the batch counting process is performed until the next batch count process is performed, when sheets are held in the stacker, the feeding roller is stopped, but the motor and the feeding unit ( transport conveyors and stacker impellers, etc.) continue to operate. Therefore, when taking out paper sheets from the stacker, there is a risk that the rotating impeller or the like may hit the fingers and injure them.

In view of these circumstances, the present invention has been developed in a batch counting type sheet counting device to achieve the function of stopping feeding and taking in sheets at the end of counting and ejecting the last sheet counted. The purpose is to make it small and lightweight.

In addition to this object, it is another object of the present invention to make it possible to safely take out paper sheets from a stacker while automating batch counting processing.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the first invention includes a delivery section that sends out paper sheets stacked and stored in a hopper one by one by a delivery roller, and a delivery section from the delivery section. A take-in section that sends out the paper sheets along the outer periphery of the take-in roller, a take-out section that carries out the paper sheets that have passed through the take-in section to the take-out side, and a counter that counts the paper sheets that have passed through the take-out section. and a drive mechanism for driving the sending section, the taking-in section, and the taking-out section, wherein the sending-out section is rotatably provided coaxially with the taking-in roller. It has a conveyance roller and a discharge roller closely attached to the outer periphery of the conveyance roller, and these rollers are configured to rotate together. , a transmission system for delivery and intake that interlocks the delivery roller and the intake roller, and a transmission system that is provided on the input side of the transmission system for delivery and intake, and that is provided on the input side of the transmission system for delivery and intake so that only the rotation of the drive shaft when the motor rotates forward is used for delivery and intake. a first one-way clutch that transmits the transmission to the transmission system; and a second one-way clutch that is provided between the drive shaft and the delivery section and transmits only the rotation of the drive shaft when the motor rotates in the normal direction to the roller of the delivery section. , a rotation direction conversion member that rotates in a direction opposite to the rotation direction of the drive shaft in conjunction with the drive shaft, and a rotation direction conversion member that is provided between the rotation direction conversion member and the unloading section when the motor is reversed. and a third one-way clutch that transmits only the rotation of the roller to the roller of the carrying-out section.

In addition to the configuration of the first invention, a second invention includes a stacker that accommodates paper sheets discharged from a discharge section, a sensor that detects the presence or absence of paper sheets in the stacker, and a motor that controls a drive mechanism. The control means rotates the motor in the forward direction until the number of sheets counted by the counting means reaches a set number, and when the set number is reached, rotates the motor in the reverse direction until the number of sheets counted by the counting means is completed. The motor is then stopped and restarted in response to a signal from the sensor when the paper sheet in the stacker is removed.

Note that it is preferable that the unloading section is provided with an impeller that hits the trailing edge of the sheet sent from the unloading roller to the stacker.

[Effect]

According to the configuration of the first invention, if the motor is rotated in the normal direction during counting, the rotation is applied to the sending roller, the taking-in roller, and the roller of the unloading section through the first and second one-way clutches, respectively. By being transmitted, paper sheets are continuously sent out, taken in, and carried out. Moreover, if the motor is reversed at the end of counting, the transmission of rotation to the sending roller and the taking-in roller is cut off and these rollers are stopped, while the rotation of the motor in the reverse direction is caused by the rotation direction changing member and the taking-in roller. The final sheet is conveyed by being converted into the normal rotation direction via the third one-way clutch and transmitted to the rollers of the conveyance section.

Further, according to the configuration of the second invention, when the batch counting process is completed by the forward rotation of the motor until the set number of sheets is reached, and the reverse rotation of the motor from the time when the set number of sheets is reached until the ejection of the sheets is finished, the motor is rotated. This stops all moving parts, and then, when sheets are removed from the stacker, the motor is restarted and the batch counting process is automatically performed.

〔Example〕

Embodiments of the present invention will be described based on the drawings. Based on the figure J5, in the example, the present invention is applied to a total of 0 banknotes.

FIG. 1 schematically shows an apparatus according to a first embodiment of the present invention.

In this figure, a hopper 3 in which a large number of banknotes 2 are stacked and accommodated is provided at the upper part of the device main body 1.
A delivery port 4 is formed at the lower end of one side. Hopper 3
An eccentric delivery roller 6 is arranged below the hopper 3 and faces into the hopper 3 through a notch 5 in the bottom surface of the hopper 3. The hopper 4 and the delivery roller 6 constitute a delivery section. The banknotes 2 in the hopper 4 are delivered one by one from the delivery port 4 by the rotation of the delivery roller 6, and are taken in by a take-in roller 8, which will be described later. The delivery roller 6 is attached to a delivery roller shaft 7, and the delivery roller shaft 7 is rotatably supported by the apparatus main body 1.

A take-in roller 8 is provided below the delivery port 4, and a thickness adjusting member 9 and a guide roller 10 are arranged near the delivery port 4, and a guide roller 10 is disposed in the vicinity of the delivery port 4. A guide member 11 is provided along the outer circumference of the take-in roller 8 in a range extending to a predetermined position below the take-in roller 8. The taking-in roller 8, the guide roller 10, the guide member 11, etc. take the banknotes sent out from the delivery port 4 to the taking-in roller 5.
8 and the guide roller 10, a taking-in portion is configured to take in the food and feed it along the outer periphery of the taking-in roller 8. The take-in roller 8 is attached to a take-in roller shaft 12, and the take-in roller shaft 12 is rotatably supported by the apparatus main body 1.

Further, a conveyance roller 13 is provided coaxially with the intake roller 8 . For this conveyance, the roller 13 is used as the take-in roller 8.
As shown in FIGS. 3 and 4, it is rotatably supported on the take-in roller shaft 12 via a bearing 13a on the side of the take-in roller 8. A first carry-out roller 14 and a second carry-out roller 15 are disposed outside the lower part of the m-feed roller 13 corresponding to the vicinity of the terminal end of the take-in section so as to be in close contact with the circumferential surface of the carry roller 13. 13 to 15 are configured to rotate together.

Then, the banknotes 2 that have passed through the receiving section pass between the transport roller 13, the first unloading roller 14, and the second unloading port 2 and 15, and are unloaded to the stacker 17 for banknote retrieval provided at the bottom of the device main body 1. It is now possible to do so. The first carry-out roller 14 is located on a drive shaft 18, and the second carry-out roller 15 is attached to an auxiliary drive shaft 19.

A count sensor 20 is provided near the unloading section. This count sensor 20 detects the bill 2 when it passes through the delivery section, and is composed of, for example, a light emitting element and a light receiving element. A counter in the control circuit constitutes a counting means. Furthermore, a motor 21 capable of forward and reverse rotation is provided at the lower part of the device main body 1 . Then, a control circuit (not shown) drives the motor 21 in the forward rotation direction when a counting start command is issued by key operation, and stops the motor 21 when the count sensor 20 reaches the set number of sheets. Then, the motor 21 is driven in the reverse direction for a predetermined period of time. Note that the driving of the motor 21 in the forward rotation direction may be started in response to a signal from a sensor that detects when the banknotes 23 are stacked and stored in the hopper 3.

On the front side of the main body 1 of the device, there are provided an operation section 22 for setting the number of banknotes to be counted, commanding the start of counting, etc., and a display section 23 for displaying the counted value, etc. (see Fig. 2).
.

A drive mechanism for transmitting the rotation of the motor 21 to drive each of the above-mentioned parts will be explained with reference to FIGS. 2 to 4.

A pulley 25 and a gear 26 are attached to one end of the drive i11@18, and the pulley 25 and motor 21
The rotation of the motor 21 is transmitted to the drive shaft 18 by a belt 28 that is wrapped around a pulley 27 provided on the output shaft of the motor 21 . In addition, pulleys 29 and 30 are attached to one end of the intake roller shaft 12 and one end of the delivery roller shaft 7, respectively, and a belt 31 wrapped around these pulleys 29 and 30 connects the intake roller shaft 12 and the delivery roller. The shaft 7 is interlocked with the shaft 7, thereby forming a delivery/take-in transmission system that interlocks the take-in roller 8 and the delivery roller 6.

A gear 32 is attached to the other end of the drive shaft 18.
A gear 33 that meshes with this gear 32 is connected to the intake roller shaft 12.
It is attached to the other end side (input side of the transmission system for delivery and intake) via a first one-way clutch 34. This first
The one-way clutch 34 is connected to the drive shaft 18 during forward rotation of the motor.
Only the rotation of the roller is transmitted to the take-in roller shaft 12.

Further, the first delivery roller 14 is attached to the drive shaft 18 via a second one-way clutch 35. The second one-way clutch 35 transmits only the rotation of the drive shaft 18 during normal rotation of the motor to the first delivery roller 14 .

Auxiliary drive shaft 1 to which the second carry-out roller 15 is attached
One end has a gear 26 attached to the drive shaft 18.
A gear 36 serving as a rotational direction changing member that meshes with the drive shaft and rotates in a direction opposite to the rotational direction of the drive shaft is engaged several times via a third one-way clutch 37. This third one-way clutch 37 transmits only the rotation of the gear 36 when the motor is reversed to one auxiliary 5 drive shaft.

In FIGS. 3 and 4, one pair of each of the sending roller 6, the taking-in roller 8, the conveying roller 13, and the carrying-out roller 14.15 are provided. For rollers other than 13.14°15 (such as the guide roller 10 shown in FIG. 1), please follow the above drive i.
Since it is not directly related to power transmission by the 1+ mechanism, illustration is omitted in FIGS. 3 and 4.

The operation of the counting device in this actual flow example as described above will be explained next.

When there is a command to start counting by key operation, etc., the motor 21 is driven in the forward rotation direction (arrow a) as shown in Fig. 3.
), and in conjunction with this, the drive shaft 18 also rotates in the normal rotation direction (
Arrow b). In this forward rotation driving state, the rotation of the drive shaft 18 is transmitted to the intake roller shaft 12 via the gear 1' 32, 33 and the first one-way clutch 34, and the belt 31
As a result, the sending roller 6 and the taking-in roller 8 rotate six times in a predetermined bill feeding direction (arrows c, cl). Further, the rotation of the drive shaft 18 is controlled by the unloading roller 1 via the second one-way clutch 35.
4, and from the first carry-out roller 14 to the conveyance roller 1
3. By transmitting the rotation to the second U & output roller 15, these rollers 13, 14 degrees 15 rotate in a predetermined banknote output direction (arrow e).

f, g>. At this time, rotation transmission is cut off in the third one-way clutch 37 between the gear 36 and the auxiliary drive shaft 19, and the gear 36 enters an idling state.

In this way, the sending out of banknotes by the sending section, the taking in of banknotes by the taking in part, and the taking out of banknotes by the taking out part are performed continuously, and while these operations are being performed, the count sensor 20 shown in FIG. Banknotes 2 are counted.

Once the set number of banknotes 2 have been counted, the motor 21 is temporarily stopped in response to signals from the counter 1 to the sensor 20, and then the motor 21 is driven in the reverse direction as shown in FIG. a'), and in conjunction with this, the drive shaft 18
also rotates in the reverse direction (arrow b'). In this reverse drive state, the first one-seven-way clutch 34 cuts off rotation transmission to the take-in roller shaft 12 side, so the take-in roller 8 and the delivery roller 6 are stopped. In addition, the second one-way clutch 35
Also, the transmission of rotation from the drive shaft 18 to the first carry-out roller 14 is cut off, but the rotation transmitted from the motor 21 to the gear 26.36 is transmitted to the auxiliary drive shaft 19 via the third one-way clutch 37, Rotation is transmitted from the second carry-out roller 15 to the conveyance roller 13 and the first carry-out roller 14.

Even if the motor 21 and drive IM 18 are in the reverse rotation drive state, the rotation direction is changed by the gear 26.36, so the rollers 13, 14.15 rotate in the same direction as in the normal rotation drive state (arrow e.

f, Cl). In this way, while the sending out of banknotes by the sending out section and the taking in of banknotes by the taking in section are stopped, the unloading section is operated and the final counted banknotes remaining in the unloading section are taken out.

5 to 8 show an apparatus according to a second embodiment of the invention. In this embodiment as well, the hopper 3 and the delivery roller 6 provided below the hopper constitute a delivery unit that delivers the banknotes 2 one by one, and the take-in roller 8 provided on the take-in roller shaft 12 and guide roller 1
0 and the guide member 11, etc., constitute a taking-in section that takes in the banknotes 2 sent out from the sending out section and sends them along the outer periphery of the taking-in roller 8. The banknotes 2 that have passed through the receiving section are transferred to the stacker 1 by the freely supported transport roller 13 and the first and second transport rollers 14 and 15 that are in close contact with the peripheral surface of the transport roller 13.
The configuration of the unloading section 7 for unloading is the same as in the first embodiment. Further, the drive mechanism for driving the delivery section, the take-in section, and the carry-out section also has the structure shown in FIGS. 3 and 4, as in the first embodiment. In other words, the transmission mechanism between the motor 21 and the drive@18, the intake roller shaft 1
2 and the delivery roller shaft 7, gears 32, 33 and the first one-way clutch 34 between the drive shaft 18 and the delivery roller shaft 12, and the drive shaft 18 and the first delivery roller 14. The second one-way clutch 35 between the drive shaft 18, the second one-way clutch 35, the second unloading roller 15, the gear 26, 36 between the drive shaft 18, the third one-way clutch 37, etc. When the motor rotates in the normal direction, each roller 6.8.13.14.15 is driven to rotate in a predetermined direction, and when the motor rotates in the reverse direction, rotation transmission to the delivery section and the intake section is cut off, and the rollers 13 and 15 of the delivery section are rotated.
Only 14 and 15 are rotated in the same predetermined direction as when the motor rotates normally.

In this embodiment, the elements 20a and 20b constituting the count sensor 20 that detects banknotes passing through the delivery section are located at two locations spaced at a predetermined distance in the axial direction of the delivery section so that they can also be used for checking stubs, etc. are located in each. Also,
The stacker 17 that holds the banknotes 2 carried out from the carry-out section is provided with a sensor (hereinafter referred to as stacker sensor) 41 that detects the presence or absence of banknotes in the stacker 17.

This stacker sensor 41 is composed of, for example, a transmission type sensor, and its light emitting element 41a and light receiving element 41b are arranged in the lower part and the upper part of the stacker 17. On the other hand, the hopper 3 is provided with a sensor (hereinafter referred to as a hopper sensor) 42 that detects the presence or absence of banknotes in the hopper 3 . This hopper sensor 4
2 is a reflective sensor, for example, and is attached to the bottom plate of the hopper 3.

Each sensor 20, 4L 42 mentioned above and each key 45, 46 mentioned later
．． The signal from 47 is sent to the control circuit 4 that controls the motor 21.
3 is entered. This control circuit 43 starts the motor 21 when the start key 45 is pressed while the banknotes 2 are present on the hopper 3. In particular, in this embodiment, as will be described in detail later based on a flowchart, in order to automate the batch counting process of counting banknotes 2 in units of a set number, the number of banknotes counted based on the signal from the count sensor 20 reaches the set number. The motor 21 is rotated forward until the set number of bills is reached, and when the set number of bills is reached, the motor 21 is rotated in the reverse direction for a certain period of time and then stopped. The control circuit 43 is configured to restart the motor. Further, when such batch counting processing is repeated 2 times, the accumulated count value is outputted from the control circuit 43 to the count display section 48.

Panel 44 for operation and display on the front side of the device main body 1
As shown in FIG. 7, the operation section is provided with a start key 45, a preset key 46 for selecting and changing the set number of sheets, and a clear key 47, and as a display section, a counted sheet number display section 48 is provided. and set number of sheets display 11149
is provided, and there is also a display section for error and warning displays (
(not shown) is provided. Above preset key 46
is for changing the set number of bills.The set number of bills can be multiple types such as 10, 20, 25, 50, etc., and the total number of bills in the hopper can be counted instead of batch counting. Infinity (oo), which means ``0'', is predetermined, and the set number of sheets is changed each time the preset key 46 is operated, and the set number of sheets selected in this way is displayed on the set number of sheets display 8b-49. The clear key 47 is used to clear count values and the like.

In Fig. 5, the stacker 17 provided on the banknote take-out side has a fixed bottom plate 1 that is inclined forwardly downward.
7a, and a movable support plate 17b provided perpendicularly to the fixed bottom plate 17a, and the banknotes 2 carried out from the carry-out section are placed on the fixed bottom plate 17a by the movable support plate 17b.
It is designed to be stacked and held along the same lines. The movable support plate 17b is attached to the link mechanism 51 via a bracket 52, and is maintained perpendicularly to the fixed bottom plate 17a by the link mechanism 51, and is moved inward and outward within a certain range (indicated by solid lines in FIG. 5). It is possible to move within the range from the inner side position to the outer side position shown by the two-dot chain line. Since the link mechanism 51 is biased by the spring 53, the movable support plate 17b is normally in the inward position, and when the number of bills 2 in the stacker 17 increases, the movable support plate 17b is movably supported accordingly. The plate 17b moves outward (to the front of the main body of the apparatus), and the movable support plate 17b can also move outward in response to an external force when taking out banknotes from the stacker 17. An impeller 54 for correcting the posture of the banknotes 2 fed into the stand 3 force 17 is provided in the unloading section of the stacker 17 of the structure. The blades 54a are attached to the auxiliary drive shaft 19 on each side of the pair of second conveyance rollers 15.Then, when the banknote 2 passes between the conveyance roller 13 and the second discharge roller 15, While the blade 54a is
is pressed down by the banknote 2, but when the banknote 2 passes the second carry-out roller 15, the blade 45a stands up and hits the rear end of the banknote 2, thereby moving the movable support plate 17b of the stacker 17.
The posture of the banknote 2 rising along the direction is corrected.

In step S35 following the YES determination in step S35, the flag Fb is set to zero. In this state, if there are banknotes in the hopper 3, step 83 follows the YES determination in step S2 and the YES determination in step S9.
At step 6, the presence or absence of banknotes in the stacker 17 is checked based on the signal from the stacker sensor 41, and while there are banknotes in the stacker 17, the process of returning to step S1 via the process from step S3 onwards is repeated. Motor 219 remains stopped. During this time, press the start key 4.
5 is erroneously operated, following the YES determination in step S6 and the NO determination in step S14, a warning is displayed in step 837, and then the process returns to step S1.

When the banknotes in the stacker 17 are taken out from the state after the batch counting described above, the determination in step 836 becomes YES, the batch counter value cb is cleared to O in step 838, and then the batch counter value cb is cleared to O in step 839. The determination as to whether Ca≠O is YES, in which case step S15
Move to. Therefore, the motor 21 is restarted and the batch counting process described above is performed again.

The banknotes in the hopper ran out during the counting process.4 When the banknotes in the hopper 3 run out during the counting process, step S described above is performed.
In step S19, the flag "a" is set, and in step S17, a state in which banknotes are not sent for a certain period of time (NG) is set.
) is determined, the process moves to step 834 and the motor 21 is stopped.
Return to step S1. After that, YES in step S1
In step S40 following the determination of , it is checked whether or not a new banknote has been placed in the hopper 3. If a new banknote has been placed, the flag Fa is cleared in step 841, and then in step S42, the flag Fa is cleared. 0<Cb<set number of sheets and fc
a≠O]. If this determination is No, the process moves to step S2, but if it is YES, the process moves to step S15 and subsequent steps. Therefore, if the banknotes in the hopper 3 run out before the set number of banknotes is reached during batch counting a, and the counting process is interrupted, then when banknotes are replenished, the batch counting process will be restarted from the state it was in when it was interrupted. Ru.

If there is an error, etc. If a device error (NG) is determined in step S20 during batch division processing, the motor 21 is stopped in step S43, and an error is displayed in step 844. , the clear key is checked in step S45, and when the clear key is turned ON, the motor 21 is reversed for a certain period of time in step S46, and the data is cleared in step 847, and then the process returns to step s1. Similar processing is performed when it is determined that the banknote stub or the like is defective (NG) in the banknote check at step 823 or step S33.

According to the above control, when batch counting is performed after a desired set number of sheets is selected by operating the preset key 46, the motor 21 is initially started in response to the start key operation. Then, by rotating the motor 21 in the normal direction, the feeding section, the taking-in section, and the taking-out section are operated while counting is performed, and when the set number of sheets is reached, the motor 21 is rotated in the reverse direction, and the sending-out section and the taking-in section are stopped. Only the unloading section is operated, and then the motor 21 is stopped when the banknotes have been unloaded. Thereafter, the motor 21 is restarted when the banknotes 2 are taken out from the stacker 17. In this way, batch counting processing is automatically performed.

Moreover, when there are banknotes in the stamper 17 during each batch counting process, the motor 21 is stopped, and the rollers 13 to 15 and the impeller 5 of the unloading section are
Since the banknotes 4 are also stopped, banknotes can be safely taken out from the stacker 7.

In addition, in the above control, it is also possible to add a stop function that interrupts the counting operation as desired during the counting process. In this case, for example, the start key 45 is also used as a stop key, and the counting operation after the start is stopped. If the start key 45 is pressed, the determination in step S22 is Y.
The process from step S27 onwards may be performed in the same way as in the case of ES. In addition, the specific example of the control and the structure of the device may be changed in design without departing from the gist of the present invention.

Further, the counting device of the present invention can be used to count various paper sheets in addition to banknotes.

〔Effect of the invention〕

As described above, according to the counting device according to claim 1, when the motor rotates normally, the rotation is transmitted from the drive shaft to the delivery roller and the take-in roller via the first one-way clutch, and The rotation is transmitted to each roller in the delivery section via the two one-way clutches, causing each roller to rotate in a predetermined direction, and when the motor reverses rotation, the transmission of rotation is cut off at the first one-way clutch, thereby preventing the delivery. While the roller and the take-in roller are stopped, the rotation is transmitted to each roller of the unloading section via the rotational direction conversion member and the third one-way clutch, so that each roller of the unloading section is rotated in the same direction as when the motor rotates forward. It is configured to rotate.

Therefore, when performing batch counting to count a set number of banknotes, all you need to do is run the motor in the forward direction during counting, and rotate the motor in the reverse direction when counting is complete, so that the paper sheets can be sent out, taken in, and taken out continuously during counting. A single motor can perform the function of carrying out the final count, and the function of carrying out the last sheet to be counted while stopping feeding and taking in the sheets at the end of counting. Furthermore, since there is no need to provide a heavy object such as an inertial drum in the drive system, the device can be made lightweight and compact.

4. According to the invention set forth in claim 2, in addition to the above configuration, when the set number of sheets is reached by the counting process, the motor is reversed until the conveyance of the sheets is completed and then stopped, Since a control means is provided to restart the motor in response to a signal from a sensor when a leaf is taken out, in addition to the above effects, batch counting, which counts sheets by a set number of sheets, can be performed by counting sheets from the stacker. This can be done automatically in response to the unloading process, and all moving parts, including the unloading section, are stopped when there are sheets in the stacker during each batch counting process, so sheets can be taken out safely. It is something that can be done.

In addition, in this apparatus, if an impeller is provided in the unloading section to hit the rear end of the sheet being sent from the unloading roller to the stacker, the posture of the sheet being sent into the stacker can be corrected. be able to.
