The bundling module control unit 59 has a module CPU 61a, a bundling controller, a motor controller 61b, and a motor controller 61c. The bundling controller, the motor controller 61b and the motor controller 61c are electrically connected to the module CPU 61a.

The module CPU 61a is installed on the control board. The module CPU 61a receives supply of electric power and the like from the control board. Further, the module CPU 61a may control each part through a control board.

The module CPU 61a controls the power supply to the first power supply system 63 and the second power supply system 67. [ That is, the module CPU 61a controls the bundled-module power box 59a and causes the bundled-module power box 59a to supply power to the first power supply system 63 and the second power supply system 67. [ When the bundling module 60 is in a standby mode, which will be described later, the module CPU 61a stops power supply to the first power supply system 63. [ The first power supply system 63 and the second power supply system 67 may be physically independent electrical systems or the module CPU 61a may be an independent electrical system by executing the firmware.

The bundling controller controls the motor controller 61b and the motor controller 61c based on an instruction from the module CPU 61a.

The motor controller 61b controls the motor 63a. The motor controller 61c controls the backup motor 78. [

The bundle module power box 59a supplies electric power to the control board of the module CPU 61a. Further, the bundle module power box 59a supplies each part of the bundle module 60 based on the control of the module CPU 61a. Each part of the bundling module 60 operates with the power supplied by the bundling module power box 59a.

The bundled module power box 59a supplies power to the first power supply system 63 and the second power supply system 67 based on the control of the module CPU 61a. When the first power supply system 63 and the second power supply system 67 are physically independent power systems, the bundled module power box 59a includes a first power module for supplying power to the first power system 63, And a second power module for supplying power to the second power system (67). The bundled-module power box 59a turns on or off the first power module and the second power module based on the control from the module CPU 61a to switch the first power system 63 and the second power system 67, Lt; / RTI &gt; When the first power supply system 63 and the second power supply system 67 are independent power supply systems by the firmware, the bundled-module power supply box 59a is connected to the first power supply system 63 and / And supplies power to the second power supply system (67).

The first power supply system 63 can not receive the power supply when the bundling module 60 is in the standby mode. That is, when the bundling module 60 is in the standby mode, the module CPU 61a stops the power supply to the first power supply system 63. [

When the bundling module 60 is in the standby mode, the first power supply system 63 supplies electric power to a portion where there is no problem even if the power supply is stopped. The first power supply system 63 is a system for supplying electric power to the motor 63a, the heater 69 and the display device 71, for example.

The motor 63a operates other than the backup 75 in the bundling module 60. [ For example, the motor 63a is a general name of a motor for driving the impeller accumulator 66, a motor for driving the banknote clamper 88, and a motor for driving the sheet carrier 82. [

The second power supply system 67 is also supplied with power even when the bundling module 60 is in the standby mode. That is, the module CPU 61a does not stop the power supply to the second power supply system 67 even when the bundling module 60 is in the standby mode.

When the bundling module 60 is in the standby mode, the second power supply system 67 supplies power to the problematic part when the power supply is stopped. The second power supply system 67 is a system for supplying electric power to, for example, the backup motor 78, the sensor 67a, and the inter-board communication unit 67b.

The sensor 67a is installed in each unit in the bundling module 60 to detect the position of the banknote P and the occurrence of jamming or the like. The sensor 67a transmits the detected information to the module CPU 61a.

The inter-board communication unit 67b is an interface for communicating with other module CPUs (i.e., module CPU 13a and module CPU 177a). The module CPU 61a exchanges data with another CPU module via the inter-board communication unit 67b. The inter-board communication unit 67b may be an interface for LAN communication, for example.

Next, an operation example of the paper sheet processing apparatus 1 will be described.

The paper sheet processing apparatus 1 may be in the on state, the off state, and the standby mode.

Here, an example of operation when the paper sheet processing apparatus 1 changes to the on state, the off state, or the standby mode will be described.

The on state is a state in which the power of the paper sheet processing apparatus 1 is turned on and the paper sheet processing apparatus 1 collects the banknotes P and binds them together. The off state is a state in which the power of the paper sheet processing apparatus 1 is turned off and all operations of the paper sheet processing apparatus 1 are stopped.

The standby mode is a state in which the power of the paper sheet processing apparatus 1 is turned on but the operation of each section of the paper sheet processing apparatus 1 is stopped. In the stand-by mode, power is supplied to a part of the paper-sheet treating apparatus 1 so as to be immediately operable, but no power is supplied to other parts.

When the operation state enters the standby mode, the module CPU 13a causes the main module power box 12a to stop supplying power to each section in the main module 10. [ As a result, the motor, the sensor, the display unit, and the like in the main module 10 are stopped. The module CPU 13a causes the main module power box 12a to supply electric power to the module CPU 13a and the inter-board communication unit which is an interface for inter-board communication. Thereby, the module CPU 13a can judge whether or not the release switch is depressed, and can switch the paper-sheet processing apparatus 1 from the standby mode to the on-state. The module CPU 13a also transmits to the module CPU 177a and the module CPU 61a a signal indicating that the paper-sheet processing apparatus 1 has entered the standby mode.

The module CPU 177a causes the expansion module power box 170a to stop supplying power to each section in the expansion module 174. [ Thereby, the motor, the sensor, the display unit, and the like in the expansion module 174 are stopped. Further, the module CPU 177a causes the expansion module power box 170a to supply power to the module CPU 177a and the inter-board communication unit, which is an interface for inter-board communication. Thereby, the module CPU 177a can receive the signal indicating the transition from the module CPU 13a to the ON state, and the expansion module power box 170a can supply power to each section of the expansion module 174 .

The module CPU 61a causes the bundle module power box 59a to stop supplying power to the first power supply system 63. [ Thereby, the motor 63a, the heater 69, and the display unit 71 to which electric power is supplied from the first power supply system 63 are stopped.

Further, the module CPU 61a maintains power supply to the module CPU 61a and the second power supply system 67. [ The power supply to the backup motor 78 in the second power supply system 67 is maintained so that the backup motor 78 is driven and fixed even in the standby mode. As a result, the backup 75, which operates in conjunction with the operation of the back-up motor 78, does not move downward due to gravity even during the standby mode, and moves to the position immediately before the paper- Lt; / RTI &gt; Thereby, after the standby mode is released, the bundling module 60 can further stack paper money on the paper currency P loaded in the backup 75. [

By supplying power to the module CPU 61a and the inter-board communication section 67b, the module CPU 61a can receive a signal indicating the transition from the module CPU 13a to the ON state, 59a to supply power to the respective units of the bundling module 60. [

When the standby switch for shifting the paper-sheet treating apparatus 1 to the standby mode is pressed in the on-state, the paper-sheet handling apparatus 1 shifts to the standby mode. Further, the paper sheet processing apparatus 1 shifts to the standby mode if the paper money P is not accumulated for a predetermined time.

In the standby mode, when the release switch for releasing the standby mode is pressed, the paper sheet processing apparatus 1 shifts to the ON state and accumulates and binds the banknotes P. [

Fig. 5 is a flowchart for explaining an example of operation of the paper sheet processing apparatus 1. Fig.

Here, it is assumed that the paper sheet processing apparatus 1 is in the off state.

First, the module CPU 13a of the paper sheet processing apparatus 1 determines whether the on-switch for turning on the paper sheet processing apparatus 1 is pressed (step S11). In other words, the module CPU 13a determines whether a signal indicating that the on-switch is pressed from the operation unit 17 is received.

On switch is not depressed (step S11, No), the module CPU 13a returns to step S11.

On switch is pressed (step S11, Yes), the module CPU 13a performs initialization processing (step S12). In the initialization processing, each section of the paper sheet processing apparatus 1 is brought into a state in which banknotes P can be collected and bundled. For example, in the initialization processing, the module CPU 13a transmits a command for causing the module CPU 61a and the module CPU 177a to execute initialization processing. The module CPU 13a, the module CPU 61a, and the module CPU 177a drive the motors of the respective modules, and arrange the movable parts at appropriate positions. For example, the module CPU 61a drives the motor 63a and the backup motor 78 to drive the impeller accumulator 66, the banknote clamper 88, the sheet carrier 82, the backup 75, And placed at the processing position.

When the initialization process is performed, the module CPU 13a determines whether the standby switch is pressed (step S13). In other words, the module CPU 13a judges whether or not a signal indicating that the standby switch is depressed is received from the operation unit 17.

If it is determined that the standby switch is not depressed (step S13, NO), the module CPU 13a determines whether a predetermined time has elapsed since the banknote P was accumulated last (step S14). In other words, the module CPU 13a determines whether the elapsed time exceeds a predetermined time, based on the information indicating the elapsed time transmitted by the timer 13b.

If it is determined that the predetermined time has not elapsed (step S14, NO), the module CPU 13a determines whether the OFF switch is pressed (step S15). That is, the module CPU 13a judges whether or not a signal indicating that the OFF switch is pressed is received from the operation unit 17. [

If the off switch is not depressed (step S15, NO), the module CPU 13a returns to step S13.

If it is determined that the standby switch is depressed (step S13, Yes), or if it is determined that the predetermined time has elapsed (step S14, Yes), the module CPU 13a performs standby processing (step S16) . The standby processing sets the paper sheet processing apparatus 1 to a state capable of shifting to the standby mode. The standby processing continues the processing that can not be stopped midway until the end. For example, when the impeller accumulating device 66 is conveying the banknote P, the atmospheric treatment rotates the impeller accumulating device 66 to the conveying end position of the banknote P to load the banknote P on the backup 75 . When the banknote P is on the conveying path 16, the conveying path 31 or the conveying path 62, the waiting treatment is performed by conveying the banknote P to the bundling module 60, rotating the impeller accumulating device 66 The banknote P is loaded on the back-up 75.

When the standby processing is performed, the module CPU 13a shifts to the standby mode (step S17). That is, the module CPU 13a stops power supply from the main module power box 12a. The module CPU 13a transmits a signal indicating that the paper sheet processing apparatus 1 is in the standby mode to the module CPU 61a and the module CPU 177a.

When the module CPU 177a receives the signal, the module CPU 177a stops power supply from the expansion module power box 170a.

When the module CPU 61a receives the signal, the module CPU 61a stops power supply to the first power supply system 63. [ For example, when the first power supply system 63 and the second power supply system 67 are physically independent, the module CPU 61a supplies power to the first power supply system 63 to the bundling module power supply box 59a Quot; The bundle module power box 59a receives the command and stops power supply to the first power supply system 63. [ When the first power supply system 63 and the second power supply system 67 are independent of the firmware, the module CPU 61a stops power supply to the first power supply system 63 via the firmware.

When the mode shifts to the standby mode, the module CPU 13a determines whether the OFF switch is pressed (step S18). If it is determined that the off switch is not pressed (step S18, NO), the module CPU 13a judges whether the release switch for releasing the standby mode of the paper-sheet processing apparatus 1 is pressed (step S19). That is, the module CPU 13a judges whether or not a signal indicating that the release switch is depressed is received from the operation unit 17. [

If the release switch is not depressed (step S19, NO), the module CPU 13a returns to step S18.

If it is determined that the release switch has been depressed (step S19, Yes), the module CPU 13a performs an initialization process other than the backup 75 (step S20). That is, the module CPU 13a causes the main module power box 12a to supply power to each section of the main module 10. When electric power is supplied to each unit, the module CPU 13a places each movable unit at an appropriate initial position. Further, the module CPU 13a transmits a signal indicating the transition from the standby mode to the on-state to the module CPU 61a and the module CPU 177a.

The module CPU 177a receives the signal and causes the expansion module power box 170a to supply power to each section of the expansion module 174. [ When electric power is supplied to each unit, the module CPU 13a places each movable unit at an appropriate initial position.

The module CPU 61a receives the signal and causes the bundle module power box 59a to supply power to the first power supply system 63. [ When the module CPU 61a supplies power to the first power supply system 63, the module CPU 61a drives the movable part (for example, the impeller accumulator 66, the banknote clamper 88, the seat carrier 82, etc.) ) In a suitable initial position.

When the processings other than the backup 75 are initialized, the module CPU 13a returns to step S13.

The module CPU 13a performs a termination process (step S21) when it is determined that the off switch has been depressed (step S15, Yes) or the off switch has been depressed (step S18, Yes). The termination processing puts the paper sheet processing apparatus 1 into a state in which it can shift to the off state. For example, when the backup 75 of the bundling module 60 is loading the bundled banknote P, the termination process releases the laminated banknote P from the backup 75 to the outside. When the impeller accumulating device 66 is conveying the banknote P, the finishing process rotates the impeller accumulating device 66 to the conveying end position of the banknote P, and loads the banknote P onto the backup 75. [ In this case, subsequently, the termination process releases the laminated paper money P from the backup 75 to the outside. When the termination process is performed, the module CPU 13a turns off the power of the entire paper sheet processing apparatus 1 (step S22). In other words, the module CPU 13a transmits a command to turn off power to the module CPU 61a and the module CPU 177a. Further, the module CPU 13a turns off the main module power box 12a.

Upon receiving the signal, the module CPU 177a turns off the power supply of the expansion module power box 170a. When the module CPU 61a receives the signal, the module CPU 61a turns off the power of the bundle module power box 59a.

Also, at this point, the module CPU 13a may control the bundled-module power box 59a to supply power only to the operating unit 17 that detects the depression of the on-switch. In this case, the module CPU 13a may supply power to the module power supply box 12a to the module CPU 13a so that the module CPU 13a can receive the signal that detects the depression of the on-switch.

When the entire power of the paper sheet processing apparatus 1 is turned off, the module CPU 13a ends the operation.

The paper sheet processing apparatus configured as described above can be put into the standby mode. Also, during the standby mode, the backup of the bundled module is fixed at the position at the standby mode setting and is not moved. Thereby, the backup is maintained in a state in which the paper sheets are loaded. As a result, when returning from the standby mode to the normal mode, there is no need to extract or re-insert the banknotes accumulated on the backup, and there is no need to initialize the backup. Therefore, the paper sheet processing apparatus 1 can resume the accumulation of paper sheets continuously. As described above, the paper sheet processing apparatus capable of setting the standby mode without involving the troublesome return operation and saving power can be obtained.

(Second Embodiment)

Next, the second embodiment will be described.

The paper sheet processing apparatus according to the second embodiment is different from the paper sheet processing apparatus according to the second embodiment in that the backup motor 78 receives supply of electric power from the first power supply system 63 and a point where the first gear 77a, The configuration of the second embodiment is different from that of the first embodiment in that the backup mechanism 77c can fix the backup 75 by the gear ratio and the weight of each gear. In the second embodiment, the other configuration of the paper sheet processing apparatus is the same as that of the paper sheet processing apparatus according to the first embodiment described above, and the same portions are denoted by the same reference numerals and detailed description thereof is omitted.

Fig. 6 is a block diagram schematically showing a system configuration of the paper sheet processing apparatus 1. Fig.

As shown in FIG. 6, the backup motor 78 is included in the first power supply system 63. That is, when the bundling module 60 enters the standby mode, the bundling module control unit 59 stops supplying power to the backup motor 78.

The first gear 77a, the second gear 77b and the third gear 77c of the backup drive unit constitute a fixing mechanism and the backup 75 and backup 75 of the stacked banknotes P are supported. That is, even when the power supply to the backup motor 78 is stopped, the first gear 77a, the second gear 77b, and the third gear 77c are rotated by the resistance generated from the gear ratio and the weight of each gear, The backup 75 can be supported not to move downward. The backup 75 is fixed without moving downward by a resistance generated from each gear.

The gear ratio and weight of each gear of the first gear 77a, the second gear 77b and the third gear 77c are determined according to the weight of the backup 75 and the bill P to be loaded. For example, assume that the weight of the backup 75 is 700 g, the weight of 100 sheets of banknotes P is 100 g, and the weight of the connecting shaft 76 is 300 g. In this case, the weight of the first gear 77a is 100 g, the large-diameter gear of the first gear 77a has 40 pieces of gears, and the small-diameter gear has 16 pieces of gears. In addition, the weight of the second gear 77a is 100 g, the large diameter gear of the first gear 77a has 40 pieces of gears, and the small diameter gear has 16 pieces of gears. The weight of the third gear 77a is 100 g, and the first gear 77a has 40 gears. The gear provided at the tip of the rotary shaft of the backup motor 78 has nine gears.

When the bundling module 60 is shifted to the standby mode, the module CPU 61a stops power supply to the first power supply system 63. [ Therefore, the module CPU 61a stops power supply to the backup motor 78. [

When the power supply to the backup motor 78 is stopped, the backup 75 is not supported by the driving force of the backup motor 78. [ However, since the first gear 77a, the second gear 77b and the third gear 77c support the weight of the laminated paper P stacked on the backup 75 and the backup 75, The paper sheet processing apparatus 75 can maintain the same position as that immediately before the paper sheet processing apparatus is shifted to the standby mode. Therefore, like the first embodiment, the bundling module 60 can continuously stack the banknote P on the backup 75 after the standby mode is released.

In the paper sheet processing apparatus configured as described above, the power supply to the backup motor can also be stopped in the standby mode. As a result, in the standby mode, the paper sheet processing apparatus 1 can save power more than the paper sheet processing apparatus 1 according to the first embodiment.

(Third Embodiment)

Next, the paper sheet processing apparatus according to the third embodiment will be described.

The third embodiment differs from the first embodiment in that the backup motor 78 is supplied with electric power from the first power supply system 63, the temporary accumulation unit 65 has a solenoid functioning as a fixing mechanism, a plunger, The structure is different from that of the first embodiment in that a locking portion is provided on the connecting shaft 76. In the third embodiment, the other configuration of the paper sheet processing apparatus is the same as that of the paper sheet processing apparatus according to the first embodiment described above, and the same portions are denoted by the same reference numerals and detailed description thereof is omitted.

7 is a front view of the temporary accumulation unit 65 included in the bundling module 60 of the paper sheet processing apparatus 1 according to the third embodiment.

As shown in Fig. 7, the fixing mechanism of the temporary accumulation unit 65 is provided with a latching portion, a solenoid, and a plunger provided on the connection shaft 76. [ That is, at the lower end of the connecting shaft 76, a coupling groove 93 functioning as a latching portion is formed. The coupling groove 93 is formed by a gear-shaped groove in which convex portions and concave portions are alternately arranged in the vertical direction.

The solenoid 90 and the plunger 91 are provided substantially horizontally below the gear train 77 and the plunger 91 is inserted into the solenoid 90 such that the solenoid 90 and the plunger 91 reciprocate along the horizontal direction. A compression coil spring 94 for pressing the plunger 91 in the direction protruding from the solenoid 90 is provided in the solenoid 90. Further, a fixing member 92 is provided at the tip of the plunger 91. The fixing member 92 has a concave / convex engaging portion engaging with the engaging groove 93.

The solenoid 90 and the plunger 91 are disposed opposite to the connection shaft 76 and the plunger 91 is fixed to the distal end of the fixing member 92 by engaging with the coupling groove 93 of the connection shaft 76 And a releasing position spaced apart from the engaging groove 93, as shown in Fig. When the solenoid 90 is energized, the plunger 91 is drawn into the release position by the magnetic field generated from the solenoid. When the energization of the solenoid 90 is stopped, the plunger 91 is pressed by the compression coil spring 94 and moves to the fixed position. When the plunger 91 moves to the fixed position, the fixing member 92 is engaged with the coupling groove 93 of the coupling shaft 76 to fix the coupling shaft 76. [ Thereby, the connection shaft 76 and the backup 75a are fixed at the stop position to prevent movement.

When the backup motor 78 moves the backup 75, the module CPU 61a of the bundling module 60 controls the flow of current to the coil of the solenoid 90, and the plunger 91 is moved to the solenoid 90, And enters the inside. As a result, the fixing member 92 is spaced from the connection shaft 76, so that the backup motor 78 can move the backup 75.

Fig. 8 is a block diagram schematically showing a system configuration of the paper sheet processing apparatus 1. Fig.

As shown in Fig. 8, the first power supply system 63 includes a backup motor 78 and a solenoid 90. As shown in Fig.

Thereby, when the paper sheet processing apparatus 1 is set in the standby mode, the power supply to the backup motor 78 and the solenoid 90 is stopped.

The module CPU 61a forms a state in which the stationary member 92 contacts the connection shaft 76 by the waiting process and then shifts to the standby mode.

When the paper sheet processing apparatus 1 is shifted to the standby mode, the module CPU 61a stops power supply to the first power supply system 63. [ Accordingly, the module CPU 61a stops power supply to the backup motor 78 and the solenoid 90. [

When the power supply to the backup motor 78 is stopped, the backup 75 is not supported by the driving force of the backup motor 78. [ However, the fixing member 92 provided at the tip of the plunger 91 is pressed against the connection shaft 76 by the stress of the spring. As a result, the backup 75 is continuously fixed by the fixing member 92 provided at the front end of the plunger 91, so that the backup 75 can maintain the same position as the position immediately before the paper sheet processing apparatus is shifted to the standby mode. Therefore, like the first embodiment, the bundling module 60 can continuously stack the banknote P on the backup 75 after the standby mode is released.

The paper sheet processing apparatus structured as described above can also stop supplying power to the backup motor in the standby mode as in the second embodiment. As a result, in the standby mode, the paper sheet processing apparatus 1 can save power more than the paper sheet processing apparatus 1 according to the first embodiment. Further, the paper sheet processing apparatus can fix the backup regardless of the gear ratio and the weight.

While several embodiments have been described, these embodiments are provided by way of example and are not intended to limit the scope of the invention. These new embodiments described herein can be implemented in various other forms, and various omissions, substitutions, and alterations can be made without departing from the gist of the present invention. Such forms and modifications within the scope and spirit of the present invention are included in the appended claims and their equivalents.
