  Money processing equipment represented by automated teller machines is installed not only outdoors, but also indoors near the entrance of buildings and near glass walls. May receive direct light. For this reason, the light receiving element of the sensor installed at a site where strong external light is directly irradiated, such as the deposit / withdrawal port, is previously installed in a place where direct light does not enter to suppress the influence of external light. However, external light reflected by the money handling apparatus itself may enter the light receiving element, and it is difficult to completely prevent the influence of external light.

  Guidance that the shutter should be closed to the user when the shutter is temporarily closed in order to determine the presence or absence of the medium because the presence or absence of the medium cannot be accurately detected due to external light entering the deposit / withdrawal port of the money handling apparatus. If the user misses and the user's hand is not pulled out of the shutter, the hand may be pinched by the shutter, which is not preferable for safety.

  Furthermore, even when a sensor for detecting whether or not there is a hand near the shutter of the deposit / withdrawal port portion is provided in order to prevent the user's hand from being caught, the hand detection sensor is affected by external light, and the user's hand is There is a case where a hand is caught due to false detection. Further, if the shutter is once closed in order to prevent the influence of external light, the transaction processing time becomes long.

  An apparatus according to the present invention is a medium handling apparatus for handling a medium, and is a medium inlet / outlet part into which a medium is input or discharged, a shutter that covers and opens the medium inlet / outlet part, and an inlet / outlet to / from the medium inlet / outlet part. A sensor that detects the medium or the user's hand, and a control unit that opens and closes the shutter according to the output value of the sensor. The control unit outputs a predetermined value when the output value from the sensor exceeds a predetermined value. The shutter is moved to the following position.

  According to the present invention, it is possible to provide a medium processing apparatus that realizes improvement of safety and reduction of transaction time.

First, features of the apparatus according to the embodiment of the present invention will be described.
An apparatus according to an embodiment of the present invention is a medium handling apparatus that handles a medium, and is provided with a medium inlet / outlet part into which a medium is charged or discharged, a shutter that covers and opens the medium inlet / outlet part, and a medium inlet / outlet part. A sensor that detects the input or discharged medium or a user's hand, and a control unit that opens and closes the shutter according to the output value of the sensor. The control unit outputs an output when the output value from the sensor exceeds a predetermined value. The shutter is moved to a position where the value is equal to or less than a predetermined value. In addition, the sensor is preferably a sensor that is set as a detection target at an upper position of a medium that is installed in the medium inlet / outlet part and that is input to or discharged from the medium inlet / outlet part. Further, the controller preferably moves the shutter to the fully open position, and then closes the shutter for a predetermined time or a predetermined distance when the output value from the sensor exceeds a predetermined value, and detects the position of the shutter. It is more preferable to move the shutter until the position detecting means detects a predetermined position. With such a configuration, the presence / absence of the user's hand can be determined in a state where the shutter is opened and the influence of external light is suppressed, so that there is a user's hand while preventing the transaction time from being prolonged. It is possible to prevent a situation in which the shutter is not closed due to an erroneous detection, or a situation in which the shutter is closed erroneously when there is no user's hand and the hand is pinched.

  In addition, after the shutter is closed for a predetermined time or a predetermined distance, the presence / absence of the user's hand is determined by the sensor, and when it is determined that there is no user's hand, the shutter is closed. Is preferred. With such a configuration, the presence or absence of the user's hand can be determined more reliably, and safety can be improved.

  In addition, the control unit monitors the output value while the shutter is moving, and moves the shutter to the position where the output value is equal to or less than the predetermined value, or moves the shutter to the fully open position and then closes the output value. It is made to move. With this configuration, the shutter stop position can be flexibly and automatically determined in accordance with the environment such as the intensity of external light and the incident angle, so that safety can be further improved.

Furthermore, an apparatus according to an embodiment of the present invention is a money handling apparatus that handles money, and a shutter that opens and closes by sliding and moving a deposit / withdrawal port portion into which money is inserted or discharged, It has a sensor that is installed at the deposit / withdrawal port and detects the upper position of the money that has been inserted into or discharged from the deposit / withdrawal port, and a controller that opens and closes the shutter according to the amount of light received by the sensor. The unit is characterized in that the shutter is stopped in a state in which the shutter is moved from the fully opened position to the partially closed side when it is determined that the amount of received light exceeds a predetermined value and is influenced by outside light. With such a configuration, when handling money such as banknotes and coins, it is possible to determine the presence / absence of the user's hand in a state in which the shutter is opened and the influence of external light is suppressed, thereby prolonging the transaction time. Preventing situations where the user's hand is erroneously detected and the shutter is not closed, and when the user's hand is not detected, the shutter is closed erroneously and the hand is pinched. It becomes possible.
Hereinafter, an embodiment of the present invention will be described. In this embodiment, a coin processing apparatus that handles coins will be described as an example.

  FIG. 1 is an external view of an automatic teller machine equipped with the coin processing device of this embodiment. The automatic cash transaction apparatus 100 is an apparatus that is installed in a financial institution or the like and performs transactions such as depositing and withdrawing cash by a user's operation, and automatically executing various transactions requested by the user. Inside, an operation unit 105 having an input / display function, a card / detail processing mechanism unit 102 having a card processing mechanism and a statement slip processing mechanism, a passbook processing mechanism unit 103, a banknote deposit / withdrawal processing mechanism unit 104, a coin The processing mechanism unit 101 is configured.

  FIG. 2 is a diagram illustrating a schematic configuration of a coin processing device 200 corresponding to the coin processing mechanism unit 101 of FIG. 1 according to the embodiment of the present invention. Here, the coin processing apparatus 200 is intended to handle not a wrapping coin but a loose coin. When a user inserts coins into the automatic teller machine 100, coins are inserted into the deposit / withdrawal port 203 of the coin processing device 200 with the shutter 201 opened, and the inserted coins are temporarily stored in the deposit / withdrawal port 203. Will be held. Here, the deposit / withdrawal port unit 203 temporarily holds the coins to be deposited and then takes the coins to be dispensed into the automatic teller machine 100 or the coins to be withdrawn conveyed from the inside of the automated teller machine. After temporarily holding it, it can be taken out. The shutter 201 is a cover that is provided above the deposit / withdrawal port portion 203 and covers the deposit / withdrawal port portion 203, and is a door that opens and closes the deposit / withdrawal port portion 203 by sliding.

  The coins taken into the inside from the deposit / withdrawal port 203 are separated one by one by the feeding unit 205 and sent out. Then, the fed coins are conveyed to the coin identifying unit 206, and the authenticity and denomination of the coins are identified. The identified coins are collectively held by the temporary holding unit 202 based on the identification result, or are conveyed and stored in the denomination stacker 208 by the deposit transfer unit 207 in denomination.

The collective stacker 210 is a stacker that collects coins discharged from the temporary storage unit 202 and the like, and the operation cartridge 211 is a cartridge in which replenishment coins are installed. Further, the vertical transport unit 209 is a transport unit for transporting coins stored in the batch stacker 210 and the operation cartridge 211 upward.
Next, the withdrawal conveyance unit 204 is a conveyance unit for conveying coins in the temporary storage unit 202 or the like to the deposit / withdrawal port unit 203. The hand detection sensor 220 is a sensor installed at the top of the deposit / withdrawal port portion 203, and detects that there is no user's hand in the deposit / withdrawal port portion 203 when the shutter is closed. This is a sensor installed at the lower part in the deposit / withdrawal port 203 for detecting the presence or absence of a medium.

  FIG. 3 is a functional block diagram of the coin processing apparatus according to the present embodiment, and corresponds to the schematic configuration diagram of FIG. Specifically, the shutter unit 301, the temporary storage unit 302, the deposit / withdrawal port unit 303, the withdrawal / conveyance unit 304, the feeding unit 305, the coin identification unit 306, the deposit / conveyance unit 307, the money type stacker 308, the vertical conveyance unit 309, The batch stacker 310, the operation cartridge 311, the memory 313, and a control unit 312 that controls them are configured. The control unit 312 has a CPU and controls the entire operation of the coin processing device 200 and communicates with a host device 314 corresponding to the automatic teller machine 100 in which the coin processing device 200 is built. An operation unit 315 corresponds to the operation unit 105 in FIG. 1 and accepts an input operation by a user.

  Furthermore, the shutter unit 301 includes an open detection sensor 322 that detects that the shutter 301 is in the fully open position, a close detection sensor 323 that detects that the shutter 301 is in the fully closed position, and a shutter motor 324 that drives the shutter 301. Consists of. Further, the deposit / withdrawal port portion 303 has a hand detection sensor 320 for detecting whether or not a hand is in the deposit / withdrawal port portion 303, and a residual detection sensor 321 for detecting the presence / absence of residual medium in the deposit / withdrawal port portion 203. Yes, the hand detection sensor 320 and the residual detection sensor 321 convert the received light amount received by the light receiving element into a digital amount via an A / D converter and confirm it as an output value.

  FIG. 4 is an enlarged view of the deposit / withdrawal port portion 303 and the shutter 301 of the coin processing apparatus 200 according to the present embodiment. Hand detection sensors 320 </ b> A and 320 </ b> B that detect the presence or absence of the user's hand are provided in the upper part of the deposit / withdrawal port 303 and in the vicinity of the shutter 301. 320A is a light emitting element, 320B is a light receiving element, and a pair serves as a detection sensor. This detection sensor can detect the presence / absence of the user's hand by setting the upper position of the medium inserted or discharged into the deposit / withdrawal port 303 as a detection target. Reference numerals 321 </ b> A and 321 </ b> B are residual detection sensors 321 that are installed in the lower part of the deposit / withdrawal port 303 and detect whether a medium such as coins remains in the deposit / withdrawal port 303. Reference numeral 321A denotes a light emitting element, and reference numeral 321B denotes a light receiving element, which function as a pair of sensors. Further, 322 is an open detection sensor 322 that detects that the shutter 301 is in the fully open position, and 323 is a close detection sensor 323 that detects that the shutter 301 is in the fully closed position. Here, the shutter 301 is driven by a shutter motor (not shown). When the shutter motor is rotated forward, the shutter 301 moves to the open side, and when it is rotated reversely, the shutter 301 moves to the closed side.

  FIG. 5 is a diagram illustrating an example of a light shielding or light transmission determination method for the hand detection sensor 220 and the residual detection sensor 221 that are necessary for controlling the coin processing device according to the present embodiment. These sensors are composed of light emitting elements such as light emitting diodes and light receiving elements such as phototransistors. In addition, unlike a sensor installed in the automatic teller machine 100, it is installed in a place where it is exposed to external light, and thus a mechanism that can withstand a certain amount of external light effect is required. Specifically, the sensor power supply of the light emitting element is controlled to be turned on and off intermittently (FIG. 5A), and the light receiving amount A2 when the light emitting element is turned on and the light receiving amount B2 when the light emitting element is turned off are respectively determined by the light receiving elements. Confirm (FIG. 5B). If the difference between the amount of light received when the light is turned on and the amount of light received when the light is turned off is smaller than a predetermined value, the sensor is determined to be in a light shielding state. By performing the determination in this way, if the light is weak external light such as a fluorescent lamp, the amount of received light is increased by the amount of external light, but both the amount of received light A3 when turned on and the amount of received light B3 when turned off are both. Since the difference is the same, there is no change in the difference, and the correct light-shielding state can be determined (FIG. 5C). However, when strong external light such as sunlight enters, similarly, the amount of received light is increased by the amount of external light. However, since the external light is very strong, the maximum amount of received light is exceeded. Then, both the received light amount A4 when turned on and the received light amount B4 when turned off are close to the maximum value, and there is no difference, and it is impossible to accurately determine whether the sensor is in a light-shielded state or in a light-transmitted state (FIG. 5D). Hereinafter, in determining the presence or absence of the influence of external light, the state of being influenced by external light means a state where the external light is very strong as shown in FIG. 5D.

  Next, the processing flow according to the present embodiment will be described with reference to FIG. 6, taking as an example the opening operation of the shutter 301 for the withdrawal transaction. Here, when the shutter 301 of the withdrawal transaction is opened, the shutter is opened when coins are released to the deposit / withdrawal port 303 and the user opens the shutter to prompt the user to remove the coins. Means. In the withdrawal transaction, when the operation unit 315 is operated by the user and a designated withdrawal amount is designated, a coin of the designated amount is discharged to the deposit / withdrawal portion 303. Here, a shutter opening process is executed. In this shutter opening process, as shown in FIG. 6, the shutter motor 324 is rotated forward (step 601). Then, it is monitored whether the open detection sensor 322 has detected the fully open position (step 602). When the fully open position is detected, the shutter motor 324 is stopped (step 603).

  Next, the hand detection sensor 320 determines whether there is an influence of external light. Specifically, in the hand detection sensor 320, when the light emitting element 320A is not emitting light, the light receiving amount read by the light receiving element 320B or an output value based on the light receiving amount (hereinafter referred to as the light receiving amount) is previously set. It is determined whether or not it is larger than a predetermined value. If the value is equal to or greater than the predetermined value, it is determined that there is an influence from external light (step 604). When it is determined that there is no influence due to external light, the shutter opening process is terminated. On the other hand, if it is determined that there is an influence due to external light, the shutter motor 324 is reversed (step 605). Then, it is monitored whether a certain time has elapsed (step 606), and when the certain time has elapsed, the shutter motor 324 is stopped (step 607). Then, the shutter closing operation ends. Thus, by rotating the shutter motor 324 in reverse for a certain period of time, the shutter 324 moves to the closed side for a certain distance, and the amount of light received by the hand detection sensor 320 becomes equal to or less than a predetermined value. As a result, the shutter plays the role of a shade (shade), and the influence of external light can be prevented. In addition, since the shutter is only partially closed, the user can remove the coin even in this state.

  In this embodiment, the shutter motor 324 is reversed for a certain period of time in order to close a part of the shutter. However, if it is a fixed amount, the shutter movement distance based on the encoder value of the shutter motor 324 is calculated and constant. A configuration in which the drive of the shutter motor 324 is controlled by detecting the movement of the distance may be employed. Alternatively, a configuration may be employed in which position detection means that can detect the position of the shutter is provided and control for moving to the position is performed. Furthermore, in this embodiment, in order to determine the influence of external light, a hand detection sensor 320 composed of a light emitting element and a light receiving element is used, but determination is made using both the hand detection sensor and the residual detection sensor 321. You may do it. In addition, a sensor different from the hand detection sensor 320 and the residual detection sensor 321 may be newly provided, or a sensor constituted only by a light receiving element may be used. By adopting such a configuration, the presence / absence of the user's hand can be determined in a state where the shutter is open and there is no influence of external light, so that the user's hand can be prevented while prolonging the transaction time. It is possible to prevent a situation in which the shutter is not closed due to an erroneous detection, or a situation in which the user closes the shutter due to an erroneous detection that there is no user's hand.

  Subsequently, the second embodiment will be described. Since the physical configuration shown in FIGS. 1 to 5 described in the description of the first embodiment and the method for determining the influence of external light are the same as the present embodiment, Detailed description is omitted. Hereinafter, the processing flow according to the present embodiment will be described with reference to FIG. 7, taking as an example the opening operation of the shutter 301 for the withdrawal transaction. Here, when the shutter 301 of the withdrawal transaction is opened, the shutter is opened when coins are released to the deposit / withdrawal port 303 and the user opens the shutter to prompt the user to remove the coins. Means. In the withdrawal transaction, when the operation unit 315 is operated by the user and a designated withdrawal amount is designated, a coin of the designated amount is discharged to the deposit / withdrawal portion 303. Here, a shutter opening process is executed. Specifically, first, the shutter motor 324 is rotated forward (step 701). Then, while the shutter motor 324 is rotating forward, the hand detection sensor 320 determines whether the state is immediately before being affected by external light (step 702). Here, the determination of the state immediately before the influence of external light is determined as follows. Determination is made based on whether or not the received light amount read by the light receiving element 320B when the light emitting element 320A of the hand detection sensor 320 is not emitting light is greater than a preset upper limit value of the received light amount that is not affected by external light. To do. When the amount of received light reaches the upper limit, there is still no influence from outside light, but when the amount of received light is further increased, the influence from outside light comes out.

  If it is determined in step 702 that the state is just before the influence of external light, the shutter motor 324 is stopped (step 703), and the shutter opening process is terminated. That is, while the shutter motor 324 is rotating forward, the external light level is monitored by the hand detection sensor 320, and when the amount of light received by the hand detection sensor 320 reaches a predetermined value, the shutter motor 324 is stopped. To do. If it is determined that the state is not immediately before the influence of external light, it is monitored whether the open detection sensor 322 detects the fully open position (step 704). If the fully open position is detected, the shutter motor 324 is stopped ( Step 703), the shutter opening process is terminated.

  As described above, when the shutter 301 detects that the shutter 301 is fully opened by the open detection sensor 322 and the shutter motor 324 is stopped, it is a case where there is no influence due to the external light. When the shutter motor 324 is stopped, there is an influence due to external light. Therefore, the shutter 301 is not moved to the fully open position, and the shutter closing operation is stopped at a position not affected by the external light. It is possible to prevent the influence of external light by using the shade as a shade.

  In this embodiment, the hand detection sensor 320 composed of a light emitting element and a light receiving element is used to determine the influence of external light. However, the determination is made using both the hand detection sensor and the residual detection sensor 321. You may do it. In addition, a sensor different from the hand detection sensor 320 and the residual detection sensor 321 may be newly provided, or a sensor constituted only by a light receiving element may be used.

  By adopting such a configuration, the presence / absence of the user's hand can be determined in a state where the shutter is opened and there is no influence of external light, so that the user's hand can be prevented while prolonging the transaction time. It is possible to prevent a situation in which the shutter is not closed due to an erroneous detection, or a situation in which the user closes the shutter due to an erroneous detection that there is no user's hand. Further, since the stop position of the shutter can be automatically and flexibly determined according to the environment such as the intensity of external light and the incident angle, safety can be further improved.

  Subsequently, the third embodiment will be described. Since the physical configuration shown in FIGS. 1 to 5 described in the description of the first embodiment and the method for determining the influence of external light are the same as the present embodiment, Detailed description is omitted. Hereinafter, the processing flow according to the present embodiment will be described with reference to FIG. 8 taking as an example the opening operation of the shutter 301 for the withdrawal transaction. Here, when the shutter 301 of the withdrawal transaction is opened, the shutter is opened when coins are released to the deposit / withdrawal port 303 and the user opens the shutter to prompt the user to remove the coins. Means. In the withdrawal transaction, when the operation unit 315 is operated by the user and a designated withdrawal amount is designated, a coin of the designated amount is discharged to the deposit / withdrawal portion 303. Here, a shutter opening process is executed. Specifically, first, the shutter motor 324 is rotated forward (step 801). Then, it is monitored whether the open detection sensor 322 detects full opening (step 802), and if full opening is detected, the shutter motor 324 is stopped (step 803).

  Next, the hand detection sensor 320 determines whether there is an influence of external light. Specifically, the received light amount read by the light receiving element 320B when the light emitting element 320A of the hand detection sensor 320 is not emitting light is higher than a preset upper limit value of the received light amount that is not affected by external light. Determine whether it is larger. If it is larger than this upper limit value, it is determined that there is an influence of external light (step 804). If it is determined in step 804 that there is no influence from outside light, the shutter opening process ends. On the other hand, if it is determined that there is an influence due to external light, the shutter motor 324 is reversed (step 805). Then, while the shutter motor 324 is rotated in the reverse direction, it is determined whether or not there is an influence due to external light (step 806). If it is determined that there is no influence from outside light, the shutter motor 324 is stopped (step 807). That is, while the shutter motor 324 is rotated in the reverse direction, the external light level is measured by the hand detection sensor 320, and the shutter motor 324 is stopped when the amount of light received by the hand detection sensor 320 becomes a predetermined value or less. To do.

  As described above, when the shutter 301 detects the full opening by the open detection sensor 322 and the reverse rotation operation of the shutter motor 324 is not performed, there is no influence by the external light, and there is an influence by the external light at the fully open position. If the shutter motor 324 is reversed and the shutter 301 is partially closed from the fully open position, the shutter 301 is stopped at a position that is not affected by the external light, and the shutter 301 is shaded. It is possible to prevent the influence of external light by playing a role.

  In this embodiment, the hand detection sensor 320 composed of a light emitting element and a light receiving element is used to determine the influence of external light. However, the determination is made using both the hand detection sensor and the residual detection sensor 321. You may do it. In addition, a sensor different from the hand detection sensor 320 and the residual detection sensor 321 may be newly provided, or a sensor constituted only by a light receiving element may be used.

  By adopting such a configuration, the presence / absence of the user's hand can be determined in a state where the shutter is opened and the influence of external light is suppressed. It is possible to prevent a situation in which the hand is mistakenly detected and the shutter is not closed, or a situation in which the user is erroneously detected and the shutter is closed and the hand is pinched. Further, since the stop position of the shutter can be automatically and flexibly determined according to the environment such as the intensity of external light and the incident angle, safety can be further improved.

  Subsequently, the fourth embodiment will be described. Since the physical configuration shown in FIGS. 1 to 5 and the method for determining the influence of external light described in the description of the first embodiment are the same as the present embodiment, Detailed description is omitted. Hereinafter, the processing flow according to the present embodiment will be described with reference to FIG. 9, taking as an example the closing operation of the shutter 301 for the withdrawal transaction. Here, the closing operation of the shutter 301 in the withdrawal transaction means a closing operation of the shutter 301 after the user finishes extracting coins. In the withdrawal transaction, when the operation unit 315 is operated by the user and a designated withdrawal amount is designated, a coin of the designated amount is discharged to the deposit / withdrawal portion 303. Here, the shutter opening process is executed, and the shutter motor 324 is driven until the shutter 301 detects the full opening regardless of the influence of external light. Then, when the user completes the extraction of coins by the residual presence / absence sensor 321 of the deposit / withdrawal port portion 303, a shutter closing process is executed.

First, the hand detection sensor 320 determines whether there is an influence of external light. Specifically, in the hand detection sensor 320, the light reception amount read by the light receiving element 320B when the light emitting element 320A is not emitting light is the upper limit value of the light reception amount that is not affected by preset external light. It is judged whether it is larger than. If the value is larger than the upper limit value, it is determined that there is an influence of external light (step 901). If it is determined in step 901 that there is an influence from external light,
The shutter motor 324 is reversely rotated (step 902). Then, it is monitored whether a certain time has elapsed (step 903), and when the certain time has elapsed, the shutter motor 324 is stopped (step 904). As a result, the amount of light received by the hand detection sensor 320 becomes a predetermined value or less. Then, the presence / absence of the user's hand is determined by the hand detection sensor 320 (step 905). If it is determined that there is a hand, the shutter 301 is not operated, the shutter is not closed, and the process ends. On the other hand, if it is determined in step 905 that there is no hand, the shutter motor 324 is reversed (step 906). Then, it is monitored whether the close detection sensor 323 detects full close (step 907). If it is detected that the shutter is fully closed, the shutter motor 324 is stopped (step 908), and the shutter closing process ends normally.

  If it is determined in step 901 that there is no influence by external light, the presence or absence of hand detection by the hand detection sensor 320 is confirmed before the shutter 301 is closed (step 905). If the hand detection sensor 320 determines that there is hand detection, the shutter 301 is not operated and the upper device 314 is notified that the shutter could not be closed, and the process ends. If the hand detection sensor 320 determines that there is no hand detection, the shutter motor 324 is reversely rotated (step 906). Then, it is monitored whether the close detection sensor 323 detects full close (step 907). If it is detected that the shutter is fully closed, the shutter motor 324 is stopped (step 908), and the shutter closing process ends normally. The withdrawal transaction is completed when the shutter can be closed in this way.

  In this embodiment, the shutter motor 324 is reversed for a certain period of time in order to close a part of the shutter. However, if it is a fixed amount, the shutter movement distance based on the encoder value of the shutter motor 324 is calculated and constant. A configuration in which the drive of the shutter motor 324 is controlled by detecting the movement of the distance may be employed. Moreover, the structure which provides the sensor which can detect a position and performs the control which moves to the position may be sufficient. Further, as described above in the second and third embodiments, the configuration may be such that the external light level is monitored by the hand detection sensor 320 and the shutter motor 324 is stopped when the amount of received light becomes a predetermined value or less. Furthermore, in this embodiment, in order to determine the influence of external light, a hand detection sensor 320 composed of a light emitting element and a light receiving element is used, but determination is made using both the hand detection sensor and the residual detection sensor 321. You may do it. In addition, a sensor different from the hand detection sensor 320 and the residual detection sensor 321 may be newly provided, or a sensor constituted only by a light receiving element may be used.

  By adopting such a configuration, the presence / absence of the user's hand can be determined in a state where the shutter is opened and the influence of external light is suppressed. It is possible to prevent a situation in which the hand is mistakenly detected and the shutter is not closed, or a situation in which the user is erroneously detected and the shutter is closed and the hand is pinched.

  In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Further, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment. Specifically, in the above embodiment, the withdrawal transaction has been described as an example.
