Description

The present invention relates to a banknote processing device.

For example, in a cashier system installed in a financial institution or the like, a small bundle of banknotes in which a predetermined number of banknotes are bundled with a paper band is stored in a storage for each denomination, or a small bundle of banknotes is withdrawn from the storage. There is a small bundle processing machine (banknote processing device) that can be used.

Inside the small bundle processing machine, a safe unit (drawer unit) having a small bundle safe (storage) for each denomination is provided. The safe section can be pulled out from the housing. For example, in a small bundle processing machine, the door is opened, and the safe section having a plurality of storages is pulled out from the inside of the machine to the door side (see Patent Document 1).

Conventionally, for security, an electromagnetic lock mechanism for fixing the safe portion and a sensor for detecting the withdrawal of the safe portion are provided in the small bundle processing machine.

Normally, when the small bundle processor is in the command standby state (so-called idle state) in which the processing command is waited from the host device, the safe portion cannot be pulled out from the housing because the electromagnetic lock mechanism fixes the safe portion.

If the safe is forcibly pulled out, the small bundle processor will be in a faulty state due to sensor detection. When a failure occurs, the small bundle processor cannot be used in that state, a close examination operation is performed at the time of recovery from the failure, the number of bundles of banknotes is counted, and the number of bundles matches the number of bundles that should be. Check if. Then, if the number of bundles counted in the scrutiny operation does not match the number of bundles that should exist, a scrutiny mismatch is displayed, and the small bundle processor cannot be used until the scrutiny results match or the administrator approves.

It should be noted that the above-mentioned scrutiny operation is also performed when the operator operates the safe unit, such as a manual loading process in which the operator loads a small bundle of banknotes and a manual collection process in which the operator takes out a small bundle of banknotes, other than when the failure is recovered. Will be done.

(A-1-3) Detailed Configuration of Small Bundle Safe Next, the configuration of the small bundle safe 10a to 10d according to the embodiment will be described in detail with reference to FIGS. 3 and 4.

Since each of the four small bundle safes 10a to 10d can basically have the same configuration, the configuration will be described below with reference to the small bundle safe 10.

FIG. 3 is a transparent perspective view showing the internal configuration of the small bundle safe 10 according to the embodiment. FIG. 4 is an internal configuration diagram showing an internal configuration of the banknote small bundle T stored in the small bundle safe 10 of the embodiment as viewed from the lateral side.

In addition, in FIGS. 3 and 4, the small bundle safe shutters 39ab and 39cd are omitted, and there is an opening 16 at the upper part of the small bundle safe 10 for storing or discharging the small bundle T of banknotes. ..

[Stage, stage urging member]
The stage 18 is a support base that supports the banknote bundles T arranged side by side in the thickness direction in the internal space of the box-shaped small bundle safe 10. The stage 18 is formed of a plate-shaped member, and as shown in FIG. 4, the upper end portion of the stage urging member 19 is fixed to the lower surface of the stage 18, and the stage 18 is raised by the stage urging member 19. It is urged in the direction (ie, the direction of the opening 16 of the small bundle safe).

An urging member such as a compression coil spring can be applied to the stage urging member 19, and the stage urging member 19 is fixedly provided between the lower surface of the housing of the small bundle safe 10 and the lower surface of the stage 18. A small bundle of banknotes T is placed on the upper surface of the stage 18, and the pusher portion 14 presses the small bundle of banknotes T placed on the stage 18 downward, so that the small bundle of banknotes T is placed on the stage. The stage urging member 19 urges the stage 18 upward against the weight of the 18 and the downward pressing force of the pusher portion 14. As a result, the stage 18 moves up and down according to the weight of the small bundle of banknotes T and the pressing force of the pusher portion 14.

[Stage position change detection mechanism]
The stage position change detection mechanism 300 detects the position of the stage 18 that moves up and down in the upward or downward direction, and outputs information regarding the amount of the position change of the stage 18 to the control unit 2.

The stage position change detection mechanism 300 includes a toothed belt 32, a connecting member 33, a driven rotation member 32a, and a stage position detection encoder 34.

The driven rotating member 32a is fixedly provided near the upper portion of the internal space of the small bundle safe 10, supports the inside of the toothed belt 32, stretches the toothed belt 32, and rotates the toothed belt 32. A roller member that rotates according to motion.

The stage position detection encoder 34 is fixedly provided near the lower portion of the internal space of the small bundle safe 10, supports the inside of the toothed belt 32, stretches the toothed belt 32, and stretches the toothed belt 32. It is an encoder that detects the amount of change in the stage position based on the rotation. For example, a rotary encoder or the like can be applied to the stage position detection encoder 34, and the shaft (not shown) rotates due to the rotation of the toothed belt 32, and the amount of rotational displacement of the shaft is converted into an electric signal (pulse waveform) to be converted into a control unit. Output to 2 (see FIG. 7).

The toothed belt 32 is an endless belt stretched by a driven rotating member 32a and a stage position detection encoder 34. A portion of the toothed belt 32 is connected to the side wall of the stage 18 by a connecting member 33, and rotates as the stage 18 moves up and down.

That is, the stage position change detection mechanism 300 provides information on the amount of position change of the stage 18 that moves upward or downward as follows, based on the rotation of the toothed belt 32 that is interlocked with the vertical movement of the stage 18. Is output to the control unit 2.

For example, when a plurality of small bundles of banknotes T are placed on the stage 18, and the highestmost small bundle of banknotes T is removed, the stage 18 moves upward due to the urging of the stage urging member 19. .. Then, in conjunction with the movement of the stage 18, the toothed belt 32 connected to the stage 18 rotates in the first direction, the axis of the stage position detection encoder 34 rotates in the first direction, and the stage position is detected. The encoder 34 converts the amount of rotational change of the shaft rotating in the first direction into an electric signal, and outputs a pulse signal.

On the contrary, for example, when the banknote bundle T is further laminated on the stage 18, the weight of the banknote bundle T and the downward pressing force of the pusher portion 14 are applied, and the stage 18 moves downward while being urged. .. Then, in conjunction with the movement of the stage 18, the toothed belt 32 connected to the stage 18 rotates in the second direction, the axis of the stage position detection encoder 34 rotates in the second direction, and the stage position is detected. The encoder 34 converts the amount of change in rotation of the shaft rotating in the second direction into an electric signal, and outputs a pulse signal.

In this way, the stage position detection encoder 34 outputs information regarding the amount of position change of the stage 18 moving upward or downward to the control unit 2.

[Guide plate]
The guide plates 21a and 21b are plate-shaped members that guide both ends of the small bundle of banknotes T in the lateral direction along the elevating direction of the stage 18. The guide plates 21a and 21b are arranged to face each other on both sides of the small bundle T of banknotes stacked on the stage 18 in the lateral direction in the internal space of the small bundle safe 10.

When the small bundle of banknotes T is stored, the guide plates 21a and 21b guide the small bundle of banknotes T onto the stage 18. Further, when the banknote bundle T is stored (deposited) and withdrawn, the guide plates 21a and 21b are in the vicinity of the opening 16 of the banknote safe 10, and the banknote small bundle T that moves up and down is the counting sensor 24. It has a function to protect it from getting caught in.

[Stopper]
The stoppers 22 are provided at four locations in the vicinity of the opening 16 of the small bundle safe 10 to support both ends of the uppermost banknote small bundle T on the stage 18 in the longitudinal direction. In other words, the stopper 22 supports the vicinity of the four corners of the banknote bundle T downward.

Each of the four stoppers 22 is positioned parallel to the upper surface of the uppermost banknote bundle T laminated on the stage 18 by a torsion spring (not shown) (the upper end position shown in FIG. 4, hereinafter, this position is referred to as the "original position". (Also referred to as)), and holds the stacked banknote bundles T with the stage 18 urged by the stage urging member 19.

In FIG. 4, each stopper 22 rotates downward toward the stage 18 side around the rotation fulcrum 22a, and the tip of each stopper 22 can be accommodated in the guide plates 21a and 21b. For example, the guide plates 21a and 21b have grooves for storing the stoppers 22, and the stoppers 22 are stored in the stoppers 22 in each groove and retracted from the storage space surrounded by the guide plates 21a and 21b. It is configured as follows. The position where the stopper 22 is retracted is called a "evacuation position".

[Counting sensor, sensor drive unit]
5 and 6 are explanatory views for explaining the process of detecting the number of bundles of banknotes by the counting sensor 24 according to the embodiment.

The counting sensor 24 is a sensor that detects the paper strip S of the banknote small bundle T stored in the small bundle safe 10 and counts the number of bundles of the banknote small bundle T.

As the counting sensor 24, for example, a reflective optical sensor can be applied. More specifically, in this embodiment, as illustrated in FIGS. 3 to 6, the case where the counting sensor 24 has three reflective optical sensors is illustrated, and each of the reflective optical sensors is illustrated. , "Sensor A", "Sensor B", and "Sensor C".

The counting sensor 24 is provided on the guide plate 21a side at a position where the paper band S of the banknote bundle T on the stage 18 can be detected, and the three reflective optical sensors “sensor A” of the counting sensor 24, The "sensor B" and the "sensor C" are arranged along the longitudinal direction of the banknote bundle T. The counting sensor 24 can move upward or downward by receiving a driving force from the sensor driving unit 27 described later.

Each of the three reflective optical sensors "sensor A", "sensor B", and "sensor C" of the counting sensor 24 passes through a slit (not shown) and irradiates light toward the paper band S of the bundle of bills T. Each sensor receives the reflected light reflected on the paper strip S, and the sensor detects the paper strip S based on the amount of the reflected light and the determination threshold value.

The sensor driving unit 27 drives the counting sensor 24 in the vertical direction along a guide rail 28 provided in the vertical direction of the small bundle safe 10.

The sensor drive unit 27 includes a toothed belt 29 that raises and lowers the counting sensor 24, a motor 30 that drives the toothed belt 29, a rotary encoder 31 that measures the amount of rotation of the motor 30, and the like.

As shown in FIGS. 4 and 5, the sensor drive unit 27 can raise and lower the counting sensor 24 from the lower end position to the upper end position in the storage space of the small bundle safe 10.

When the counting sensor 24 detects the paper strip S, the sensor driving unit 27 once moves the counting sensor 24 to the lower end position, and then starts light irradiation of the counting sensor 24. Then, the sensor drive unit 27 moves the counting sensor 24 upward from the lower end position, and the irradiated light is reflected on the paper band S, and the position where the counting sensor 24 starts to receive the reflected light is "started counting". "Position". More specifically, when the amount of reflected light received by the counting sensor 24 exceeds the threshold value, the reflected light may be received. Further, the sensor drive unit 27 moves the counting sensor 24 upward and moves the counting sensor 24 to the upper end position.

The counting sensor 24 determines that there is a paper band S when the value of the amount of reflected light received is large (exceeding the determination threshold value) in the movement from the lower end position to the upper end position, and the value of the amount of reflected light is increased. When it is small (less than the judgment threshold value), it is judged that there is no paper band S. Then, the counting sensor 24 identifies the break of the paper strip S and counts the number of small bundles of banknotes T.

(A-1-4) Configuration of Control System of Small Bundle Processing Machine FIG. 7 is a configuration diagram showing a configuration of a control system of the small bundle processing machine 1 according to the embodiment. In FIG. 7, the small bundle processing machine 1 includes a control unit 2, a storage unit 3, a sealing unit 5, an elevating mechanism unit 7, a gripping and transporting unit 9, a pusher unit 14, a counting sensor 24, a sensor drive unit 27, and a stage position change. It has an information acquisition unit 35.

[Stage position change information acquisition unit]
The stage position change information acquisition unit 35 acquires information on the position change amount of the stage 18 from the stage position change detection mechanism 300 and gives it to the control unit 2.

The stage position change information acquisition unit 35 instructs the stage position change detection mechanism 300 to enable or disable the position detection process of the stage 18 according to the instruction from the control unit 2.

[Control unit, storage unit]
The control unit 2 is a processing unit or device that controls various functions of the small bundle processing machine 1 based on a command from the control device 51 of the accounting system 50. The control unit 2 is, for example, an arithmetic processing unit centered on a CPU, and various functions are realized by executing a processing program stored in the storage unit 3.

The control unit 2 compares the value of the stage position change amount from the stage position change information acquisition unit 35 with the preset threshold value, and when the value of the stage position change amount exceeds the threshold value, the position of the stage 18 is changed. Detect that it has changed.

That is, when the control unit 2 detects that the position of the stage 18 of each small bundle safe 10 has changed, it can be considered that the small bundle T of banknotes has been illegally removed from the small bundle safe 10. When the value of the stage position change amount exceeds the threshold value, the control unit 2 may notify the control device 51 of the accounting system 50 to that effect and output or display a predetermined alarm.

Here, the threshold value for determining the value of the stage position change amount can be, for example, a value similar to the thickness of one bundle T of small bundles of banknotes sealed with a predetermined number of banknotes. According to this, when one or more bundles of banknotes T are extracted, the position of the stage 18 moves upward by at least one bundle of thickness, so that illegal extraction of the small banknotes T can be detected. ..

Further, the control unit 2 changes the position of the stage 18 of each small safe 10 at least during the command waiting period (that is, the idle state) in which the processing command from the control device 51 of the accounting system 50 is waiting. Determine if it is. In other words, the control unit 2 effectively activates the operation of the stage position change detection mechanism 300 during the command standby period, and invalidates the operation of the stage position change detection mechanism 300 during the period other than the command standby period.

The control unit 2 controls each component of the small bundle processing machine 1 according to a command from the control device 51 of the accounting system 50, and deposits and withdraws the small bundle T of banknotes, and the small banknotes stored. Counting processing of bundle T and the like are performed.

The storage unit 3 stores a program executed by the control unit 2, various data necessary for executing the process, a processing result by the control unit 2, and the like.

In the storage unit 3, for example, (a) a deposit process for storing the banknote small bundle T formed by the sealing unit 5 in the small bundle safe 10 of the corresponding denomination, and (b) discharging from the small bundle safe 10. A function to execute a withdrawal process of transporting and discharging the small bundle T of banknotes to the withdrawal port 8, (c) a counting process of counting the number of bundles T of the small bundle T stored in each small bundle safe 10. The business execution program having the above is stored in advance. Each functional means of the small bundle processing machine 1 is formed by the step of the business execution program executed by the control unit 2.

(A-2) Operation of the Embodiment The processing operation in the small bundle processing machine 1 according to the embodiment will be described below.

For example, in a store of a financial institution, when a staff member turns on the power of the accounting system 50 and power is supplied to the small bundle processing machine 1 at the start of business, the small bundle processing machine 1 sends the small bundle processing machine 1 to the storage unit 3. The stored business execution program starts automatically.

When the business execution program is activated, the small bundle processor 1 starts waiting in a command standby state (idle state) in which the control unit 2 waits for a processing command from the control device 51 of the accounting system 50.

At this time, in the small bundle processing machine 1, the small bundle safe shutters 39ab and 39cd are opened, and the stage position change detection mechanism 300 enables the stage position detection processing.

(A-2-1) Deposit Processing FIG. 8 is a flowchart showing the operation of the deposit process in the small bundle processing machine 1 of the embodiment.

When a predetermined number of banknotes are sealed with a paper band S and stored in the small bundle safe 10, a predetermined number of banknotes (for example, 100) are stored in the banknote collection section (not shown) of the accounting system 50. When the banknotes are collected, the control device 51 of the cashier system 50 transmits a deposit processing command to which the denomination of the collected banknotes is attached to the control unit 2 of the small bundle processing machine 1.

In the small bundle processor 1, when the control unit 2 receives the deposit processing command from the control device 51 of the accounting system 50 (S101), the control unit 2 performs the stage position detection process on the stage position change detection mechanism 300. Instruct invalidation (S102).

Here, the stage position detection processing is disabled when the small bundle processing machine 1 is not in the idle state but is in a state where a deposit processing command is received from the accounting system 50, and the safe unit 36 is withdrawn and the banknotes are invalidated. This is because it is difficult for the small bundle T to be illegally extracted. Further, when the deposit process is being executed, the small bundle T of banknotes is stored in the small bundle safe 10, so that the stage 18 moves up and down significantly. Therefore, even in such a case, the position change of the stage 18 is detected. This may increase the processing load. Therefore, in the state of receiving the processing command from the accounting system 50 (non-command standby state), the stage position detection processing is disabled.

When a predetermined number of bundled banknotes collected in the banknote collection unit are conveyed as a bundle and the banknote bundle is delivered to the sealing unit 5 of the small bundle processing machine 1 (S103), the sealing unit 5 delivers the banknotes. The bundle is sealed with a paper band S to form a small bundle T of banknotes (S104).

Then, in the small bundle transport path 6, the sealed small bundle T of banknotes is sandwiched, the small bundle of banknotes T is conveyed in the direction of the elevating mechanism portion 7 (see FIG. 2), and the small bundle of banknotes T is the elevating mechanism portion 7. When it is delivered to, the elevating mechanism portion 7 moves downward and stops at the position of the gripping and transporting portion 9 (S105).

The control unit 2 refers to the denomination setting information of the storage unit 3 based on the denomination information of the small bundle T of banknotes attached to the deposit processing command, and specifies the small bundle safe 10 to be transported (S106).

Then, the control unit 2 performs a storage process in the small bundle safe 10 (S107). Specifically, the transported banknote bundle T is placed on the stopper 22 of the transport destination safe 10, and the pusher portion 14 is operated to place the banknote bundle T placed on the stopper 22. Press. When the small bundle of banknotes T is pressed, the stopper 22 is rotated in the direction (downward) to retract from the storage space between the guide plates 21a and 21b, and is small against the urging force of the stage urging member 19. Push the small bundle T of banknotes into the bundle safe 10. Then, when the small bundle of banknotes T passes through the tip of the stopper 22 in the retracted position, the stopper 22 rotates in the opposite direction (upward direction) due to the urging force of the torsion spring and stops at the original position.

After confirming that the stopper 22 has stopped at the original position, the control unit 2 raises the pusher unit 14 pressing against the banknote bundle T, and the banknote bundle T is stacked on the stage 18. Store in a higher position. Then, while holding the plurality of small bundles of banknotes T stacked on the stage 18 between the pusher portion 14 and the stage 18, the stage 18 is raised by the urging force of the stage urging member 19 to the maximum. The stopper 22 is brought into contact with the upper surface of the banknote bundle T on the upper side. As a result, the small bundle T of banknotes is stored in the small bundle safe 10.

When the above-mentioned payment process is completed, the control unit 2 transmits a payment normal end notification indicating that the payment process has been completed normally to the control device 51 (S108), and the control unit 2 sends the stage position change detection mechanism 300 to the stage position change detection mechanism 300. On the other hand, the validity of the stage position detection process is instructed (S109).

Here, the stage position detection processing is enabled because the small bundle processing machine 1 is in the idle state (command standby state) after the deposit processing is completed in the small bundle processing machine 1. This is because the unit 36 is pulled out and the small bundle T of banknotes is likely to be illegally extracted.

(A-2-2) Withdrawal Processing FIG. 9 is a flowchart showing an operation of withdrawal processing in the small bundle processing machine 1 of the embodiment.

When withdrawing the small bundle T of banknotes stored in the small bundle safe 10, the control device 51 of the accounting system 50 issues a withdrawal processing command with the denomination and the number of bundles of the small bundle T of banknotes to be withdrawn. It is transmitted to the control unit 2 of the small bundle processor 1.

When the control unit 2 receives the withdrawal processing command (S201), the control unit 2 instructs the stage position change detection mechanism 300 to invalidate the stage position detection process (S202).

The control unit 2 refers to the denomination setting information of the storage unit 3 based on the denomination information of the small bundle T of banknotes attached to the withdrawal processing command, and identifies the small bundle safe 10 as the transport source (S203). ..

Then, the control unit 2 discharges the small bundle T of banknotes from the small bundle safe 10 of the transport source (S204).

Specifically, the gripping and transporting portion 9 and the pusher portion 14 are moved in the direction of the specified small bundle safe 10 and stopped on the small bundle safe 10. In order to start withdrawal of the banknote bundle T, the pusher portion 14 is operated to press the uppermost banknote bundle T held between the stopper 22 and the stage 18, and the stage urging member 19 Against the urging force, the highest-ranked banknote bundle T is pushed into the bundle safe 10. At this time, the pusher portion 14 pushes down the banknote bundle T until the tip of the stopper 22 moves from the storage space between the guide plates 21a and 21b to the retracted position. After that, the stopper 22 is rotated by a drive mechanism of the stopper 22 (not shown), the stopper 22 is stopped at the retracted position, and the opening 16 of the small bundle safe 10 is opened.

After confirming that the stopper 22 has stopped at the retracted position, the control unit 2 raises the pusher unit 14 and brings all the banknote bundles T stacked on the stage 18 to the pusher unit 14 and the stage by the stage urging member 19. The highest-ranked banknote bundle T is raised to the outside of the opening 16 while being held between the banknote and the banknote 18. Then, the ejected top-level banknote bundle T is stopped in a state of being held by the pusher portion 14.

After confirming that the uppermost banknote bundle T has stopped outside the opening 16, the control unit 2 operates the gripping and transporting unit 9 to set the lower gripping claw to the uppermost banknote bundle T and the second. It is inserted between the small bundle T of the banknote and the highest-ranked small bundle T of banknotes is gripped and pulled out with a pair of gripping claws (S205).

Then, the gripping and transporting unit 9 that grips the small bundle of banknotes T is moved in the direction of the elevating mechanism unit 7, and the small bundle of banknotes T is delivered to the elevating mechanism unit 7. The elevating mechanism 7 moves upward, and the small bundle of banknotes T is ejected from the withdrawal port 8 (S206).

When the uppermost banknote bundle T is pulled out, the control unit 2 operates the pusher unit 14 to raise the second banknote bundle T (new maximum) by the stage urging member 19. The upper banknote bundle T) is pressed, the banknote bundle T is pushed into the banknote safe 10 against the urging force of the stage urging member 19, and the second banknote bundle T is stopped at the retracted position. Push it below the tip of the stopper 22 to temporarily stop it. After that, the stop at the retracted position of the stopper 22 is released, and the stopper 22 is rotated by the urging force of the torsion spring to stop at the original position.

After confirming that the stopper 22 has stopped at the original position, the control unit 2 raises the pusher unit 14, and the small bundles of banknotes T stacked on the stage 18 are brought into the pusher unit 14 and the stage 18 by the stage urging member 19. The upper surface of the newly top-level banknote bundle T is brought into contact with the stopper 22 and re-stored while being held between the two.

The control unit 2 transmits a withdrawal normal end notification indicating that the withdrawal of the small bundle of banknotes T has been completed normally to the control device 51 (S207), and lowers the counting sensor 24 to the lower end position to stop it.

When the withdrawal process described above is completed, the small bundle processing machine 1 is in an idle state. Therefore, in order to monitor the illegal extraction of the small bundle T of banknotes, the control unit 2 causes the stage position change detection mechanism 300 to perform the stage. Instructs the validity of the position detection process (S208).

(A-2-3) Manual Loading Process and Manual Recovery Process Next, the operation of the manual loading process or the manual recovery process by the staff in the small bundle processing machine 1 of the embodiment will be described.

The manual loading process is a process in which a staff member pulls out the safe unit 36 and loads the banknote small bundle T into the corresponding small bundle safe 10. On the other hand, the manual collection process is a process in which a staff member pulls out the safe unit 36, takes out a small bundle T of banknotes from the corresponding small bundle safe 10, and collects the banknotes. Since both processes are basically performed by a staff member pulling out the safe unit 36, both processes will be described together here.

FIG. 10 is a flowchart showing the operation of the manual loading process or the manual recovery process in the small bundle processing machine 1 of the embodiment.

For example, the clerk selects the manual loading process or the manual collection process by the clerk from the transaction selection menu using the display unit 510 and the operation unit 511 of the accounting system 50, and starts each process.

The control device 51 of the accounting system 50 transmits a manual loading processing command or a manual collecting processing command to the control unit 2 of the small bundle processing machine 1.

When the control unit 2 receives the hand loading process command or the hand recovery process command in the small bundle processor 1 (S301), the control unit 2 instructs the stage position change detection mechanism 300 to invalidate the stage position detection process. (S302).

The control unit 2 opens the small bundle safe shutters 39ab and 39cd and releases the electromagnetic lock mechanism 37 in order to allow the staff to pull out the safe unit 36 (S303). The clerk pulls out the safe portion 36 from the housing of the small bundle processing machine 1 (S304).

When the clerk manually loads the small bundle T of banknotes into the small bundle vault 10, the clerk places the small bundle of banknotes T to be loaded on the corresponding small bundle of banknotes 10 and pushes the small bundle of banknotes T by hand. As a result, the stopper 22 rotates downward, the small bundle of banknotes T is placed at the top of the stage 18, and then the stopper 22 rotates upward again, and the tip of the stopper 22 is the banknote. It contacts the upper surface of the bundle T. In this way, manual loading is possible.

On the other hand, when the clerk collects the small bundle T of banknotes from the small bundle safe 10, the clerk manually moves the stopper 22 to the evacuation position while pushing the small bundle T of banknotes stacked in the small bundle safe 10 to be collected. do. Then, for example, by pulling a release lever (not shown) and returning the pushed small bundle safe 10, the small bundle T of banknotes and the stage 18 are moved onto the stopper 22 to collect the small banknote bundle T.

After that, when the safe unit 36 is returned to the housing of the small bundle processing machine 1 by the staff, for example, the switch 38 detects the storage of the safe unit 36 (S305), and the control unit 2 notifies the control device 51 of the normal end. (S306).

Then, since the small bundle processing machine 1 is in the idle state, the control unit 2 instructs the stage position change detection mechanism 300 to enable the stage position detection processing in order to monitor the illegal extraction of the small bundle T of banknotes. (S307).

(A-2-4) Scrutiny operation Next, the scrutiny operation in the small bundle processing machine 1 of the embodiment will be described. That is, the operation of the counting process of the small bundle T of banknotes at the time of scrutiny will be described.

FIG. 11 is a flowchart showing the operation of the counting process at the time of scrutiny in the small bundle processing machine 1 of the embodiment.

The scrutiny operation is an operation executed by a staff member during a manual loading process, a manual recovery process, a failure recovery, or the like. Further, the scrutiny operation can be executed by a staff member at an arbitrary timing through the accounting system 50. Here, the scrutiny operation during the manual loading process or the manual recovery process will be described as an example.

For example, in the case of manual filling processing, the display unit 510 and the operation unit 511 of the cashier system 50 are used to input the denomination and the number of bundles (loading number) of the banknote small bundle T loaded by the staff. Further, for example, in the case of manual collection, the denomination and the number of bundles (collection number) of the small bundle T of banknotes collected by the staff are input by using the display unit 510 and the operation unit 511 of the cashier system 50.

In order to count the number of bundles of bills of the input denomination, the control device 51 of the accounting system 50 transmits a counting processing command with the input denomination to the control unit 2 of the small bundle processing machine 1. ..

When the control unit 2 receives the counting processing command in the small bundle processing machine 1 (S401), the control unit 2 instructs the stage position change detection mechanism 300 to invalidate the stage position detection processing (S402).

The control unit 2 identifies the designated small bundle safe 10 based on the denomination of the small bundle T of banknotes attached to the counting processing command and refers to the denomination setting of the storage unit 3 (S403). The small bundle T of banknotes stored in the small bundle safe 10 is counted (S404).

Specifically, in the specified small bundle safe 10, the motor 30 of the sensor drive unit 27 is rotated to raise the counting sensor 24 from the lower end position to the upper end position. When the optical axes of each of the sensors A, B, and C of the counting sensor 24 reach the counting start position in the process of raising the counting sensor 24, as shown in FIG. 6, they rotate in conjunction with the rotation of the motor 30. A periodic rectangular wave (pulse signal) is output from the encoder 31, and a waveform of the amount of reflected light is output from the sensor A, the sensor B, and the sensor C. Then, when the optical axis of the counting sensor 24 reaches the upper end position, the control unit 2 receives a bundle of banknote small bundles T stored in the small bundle safe 10 specified by the waveform from the counting start position to the upper end position. Count the number.

The control unit 2 transmits a counting end notification with the counted number of bundles attached to the control device 51 (S405), lowers the counting sensor 24 to the lower end position, and stops the counting sensor 24.

After that, since the small bundle processing machine 1 becomes idle, the control unit 2 instructs the stage position change detection mechanism 300 to enable the stage position detection processing in order to monitor the illegal extraction of the small bundle T of banknotes. (S406).

The control device 51 of the accounting system 50 compares the number of bundles of the attached banknote small bundle T with the input number of loaded or collected bills, and if they match, displays that fact on the display unit 510. On the other hand, in the case of a mismatch, the control device 51 displays the fact of the mismatch and the number of bundles and the number of loaded small bundles T counted on the display unit 510 to notify the error.

(A-2-5) Unauthorized sampling detection processing Next, the operation of the illegal extraction detection processing in the small bundle processing machine 1 according to the embodiment will be described.

The illegal extraction detection process is a process for detecting the possibility that the safe unit 36 is pulled out from the housing and the banknote small bundle T is illegally extracted from the small bundle safe 10 when the small bundle processing machine 1 is in the idle state. ..

FIG. 12 is a flowchart showing the operation of the illegal sampling detection process in the small bundle processing machine 1 according to the embodiment.

First, the control unit 2 determines whether or not the stage position detection process is valid (S501), and if it is invalid, the process returns to S501, and if it is valid, the process shifts to S502.

Here, the illegal sampling detection process is performed when the small bundle processor 1 is in the idle state (command standby state). In other words, when the control device 51 of the accounting system 50 issues a processing command for each process to the small bundle processing machine 1, and the processing based on the processing command is executed in the small bundle processing machine 1, the illegal sampling detection process is executed. Not done.

When the stage position detection process of the stage position change detection mechanism 300 is enabled, the control unit 2 monitors whether or not the stage position change detection mechanism 300 has notified the stage position detection information (S502), and the stage position detection information is transmitted. When acquired, the process shifts to S503, and when the stage position detection information is not acquired, the process returns to S502.

Here, the stage position change detection mechanism 300 detects the position change of the ascending / descending stage 18.

That is, when the small bundles of banknotes T stacked on the stage 18 are illegally extracted, the small bundles of banknotes T on the stage 18 are pushed by a person who tries to illegally extract the small banknotes T, and the stage 18 Moves downward, and after the small bundle of banknotes T is pulled out, the stage 18 moves upward due to the urging of the stage urging member 19.

Then, the toothed belt 32 connected to the stage 18 rotates in conjunction with the position change of the stage 18 that moves up and down, the shaft of the stage position detection encoder 34 rotates, and a pulse corresponding to the amount of rotation change of the shaft rotates. The waveform (pulse signal) is output from the stage position detection encoder 34 to the control unit 2 as stage position detection information.

The control unit 2 counts the pulse waveform (the number of pulses) as the stage position detection information, and derives the value of the position change amount of the stage 18 based on the count value (S503).

Then, the control unit 2 compares the value of the position change amount of the stage 18 with the threshold value (S504), and when the value of the position change amount exceeds the threshold value (S504 / YES), the position of the stage 18 changes. An alarm is output to that effect (that is, there is a risk of unauthorized extraction) (S505). On the other hand, when the value of the position change amount is less than the threshold value, the process shifts to S502.

For example, when the value of the position change amount of the stage 18 exceeds the threshold value, the possibility of illegal removal of the banknote bundle T can be detected at an early stage. In that case, the small bundle processing machine 1 may execute the scrutiny operation.

That is, when it is determined that an illegal operation is detected, a scrutiny operation is executed, the number of bundles of the stored banknote small bundle T is compared with the counted number of bundles, and an alarm is displayed if they do not match. May be good.

(A-3) Effect of Embodiment As described above, according to this embodiment, when the small bundle processor is in the idle state, some work is applied to the electromagnetic lock mechanism, the switch, etc., and the safe portion is pulled out. Therefore, it is possible to detect at an early stage that an illegal operation has been performed.

(B) Other Embodiments Although various modified embodiments have been mentioned in the above-described embodiments, the present invention can also be applied to the following modified embodiments.

(B-1) In the above-described embodiment, the case where the stage position change detection mechanism unit is composed of the toothed belt 32, the connecting member 33, the driven rotating member 32a, and the stage position detection encoder 34 has been illustrated.

However, the stage position change detection mechanism unit is not limited to the above-described configuration, and can have various configurations as long as it can detect the stage position change.

For example, the stage position change detection mechanism unit may use a counting sensor 24 that can be raised and lowered by the sensor drive unit 27.

More specifically, a stage detection label is attached to the side wall of the stage 18, and the reflective optical sensor of the counting sensor 24 that moves up and down between the lower end position and the upper end position transmits the reflected light reflected on the stage detection label. The position of the stage 18 may be determined based on the amount of received light and the reflected light.

That is, when the position of the stage 18 is intermittently recorded in the idle state, the position changes between the past stage position and the current stage position, and the value of the position change amount exceeds the threshold value. , It can be determined that the position of the stage 18 has changed. That is, it is possible to detect at an early stage that the small bundle safe has been illegally extracted.

(B-2) In the above-described embodiment, the small bundle processing machine 1 is a component device of the accounting system 50, and the small bundle processing machine 1 is a control device 51, an operation unit 511, and a display unit 510 of the accounting system 50. Although the case of operating in conjunction with each other has been illustrated, the present invention is not limited to this configuration, and the small bundle processing machine according to the present invention may operate as a single small bundle processing machine.

(B-3) Further, the small bundle processing machine according to the present invention may be applied to a cash processing device having a storage for storing banknotes. When applied to a cash processing device that stores non-bundle banknotes, the threshold value for determining the value of the stage position change amount may be, for example, a value similar to the thickness of a predetermined number of banknotes.
