The bag holder 304 supports the shopping bag in an open state. The temporary placement table 306 is a table used for temporarily placing products after the barcode is read by the barcode scanner 204. The scale housing 302 incorporates a load cell unit (not shown) that converts a load of a product placed on the placement table 303a into an electric signal. An output signal from the load cell unit is output to the settlement terminal 201.

  FIG. 2 is a perspective view showing the coin discriminating apparatus 401 and the coin depositing / dispensing apparatus 1. The coin discriminating apparatus 401 includes a coin inserting unit 402 and a discriminating unit 403. The coin insertion unit 402 allows the customer to insert coins and sends the inserted coins to the determination unit 403. The determination unit 403 determines whether the coin sent from the coin insertion unit 402 is true or false and the denomination. Further, the determination unit 403 counts the determined coins for each denomination. The discriminating unit 403 discharges (injects) the genuine coins into a coin receiving unit (hopper unit) 3 that is a receiving unit of the coin depositing / dispensing device 1, and discharges the false coins to the discharging coin receiving unit 23 of the coin depositing / dispensing device 1. .

  FIG. 3 is a plan view showing the internal structure of the coin deposit / withdrawal apparatus 1. In front of the right side of the housing 2 which is a housing of the coin depositing and dispensing device 1, a coin receiving portion 3 opened upward is provided. The coin receiving unit 3 is located below the determining unit 403 of the coin determining device 401 and accepts coins input from the determining unit 403. A concave discharge coin receiving portion 23 having an open upper surface is disposed at a position on the left front side of the housing 2. The discharged coin receiving unit 23 is exposed from the base housing 202 of the payment terminal 201.

  The coin receiving unit 3 is provided with a plurality of sets of receiving sensors (detection sensors) 4 that photoelectrically detect the presence or absence of coins. In addition, the coin receiving unit 3 is provided with a receiving belt 5 that is a transport belt that transports the inserted coins toward the back (the sorting and storing unit 57). The receiving belt 5 is connected to and driven by a motor M (see FIG. 6). On the receiving belt 5, there is provided a receiving roller 6 that is positioned at one end of the coin receiving portion 3 and that feeds out the coins that are randomly input one by one. A passage sensor 56 that photoelectrically detects the presence or absence of coins is provided downstream of the receiving roller 6 in the conveying direction. A coin transport surface 7 a that supports the coin is formed at a position for receiving the coin sent out by the receiving roller 6. The coins on the coin transport surface 7a are transported while being pressed against the coin transport surface 7a by the rotation of the transport belt 7 provided on the upper surface side of the coin transport surface 7a. The conveyor belt 7 is connected to and driven by a motor M (see FIG. 6). A coin guide portion 50 that bends the conveyance direction at a substantially right angle is provided at the end portion of the conveyance belt 7. A conveying belt 8 is provided at a position continuous with the coin guide 50 so as to be substantially parallel to the width direction of the coin depositing and dispensing apparatus 1. The transport belt 8 transports coins whose transport direction is bent at a substantially right angle by the coin guide 50.

  Therefore, the receiving belt 5, the receiving roller 6, the conveying belt 7, the coin conveying surface 7a, the coin guiding unit 50, and the conveying belt 8 separate the coins on the conveying belt 7 input from the coin receiving unit 3 one by one. A coin transport mechanism 9 for transport is configured. In other words, the coin transport mechanism 9 has a receiving belt 5 provided at the bottom of the receiving unit 3, and the coin positioned on the receiving belt 5 in the receiving unit 3 by causing the receiving belt 5 to roll forward. Are conveyed toward the sorting and storing unit 57 (coin storing unit 14) described later.

  A hole base portion 31 that is a plate-like member parallel to the conveyor belt 8 is disposed below the conveyor belt 8. The hole base portion 31 is provided with six sorting holes 10 according to denomination along the conveyor belt 8. The sorting hole 10 is a hole of a metal type whose hole width dimension is gradually increased. That is, six sorting holes 10 having a size corresponding to each denomination are provided in the order of 1 yen, 50 yen, 5 yen, 100 yen, 10 yen, and 500 yen from the right side of FIG. The coins conveyed by the conveyor belt 8 fall from the corresponding denomination sorting holes 10 as described in detail with reference to FIG. The hole base 31 and the sorting hole 10 constitute a coin sorting unit 11 that sorts the coins transported by the transport belt 8 according to the denomination.

  The coin sorting unit 11 is provided with a counting sensor 12 as a second detection unit that detects coins falling from each sorting hole 10. The sorting hole 10 communicates with a coin storage portion 14 (14a to 14f) as a storage portion of an upper opening that is partitioned by denomination by a partition plate 13. The coin storage unit 14 is disposed at a position for receiving a coin dropped from the sorting hole 10 and stores the coin.

  The width of the bottom surface portion of each of the coin storage portions 14a to 14f is wider than the diameter of the coins stored in each of the coin storage portions 14a to 14f, and the coin has a diameter equal to that of the coin stored in each of the coin storage portions 14a to 14f. It is set to be narrower than the width including the thickness of. On one side of the sorting hole 10, a conveyance reference surface 10 b is formed along the conveyance belt 8.

  The coin C is pressed against the transport reference surface 10b by the transport belt 8 and transported. When the coin C transported along the transport reference surface 10b is positioned in the sorting hole 10 having a size corresponding to the denomination, the coin C falls from the sorting hole 10. Coins C that have fallen from the sorting holes 10 are stored in the corresponding coin storage portions 14. Here, the coin storage unit 14 and the coin sorting unit 11 constitute a sorting and storing unit 57 that sorts and stores coins by denomination. That is, the sorting and storing unit 57 includes the coin storing unit 14 and the coin sorting unit 11.

  A payout belt 15 is provided on the bottom surface portion of the coin storage portion 14. The payout belt 15 is rolled around a drive roller and a driven roller that are connected to and driven by a motor M (see FIG. 6).

  Further, a separation roller 18 that separates coins one by one is provided at an outlet of the coin storage unit 14 with an interval through which one coin can pass with respect to the payout belt 15. The separation roller 18 is provided across all the outlet portions.

  Furthermore, a coin aligning unit 19 is provided at the exit of the coin storage unit 14 to align a predetermined number of coins in a line and wait. The coin alignment unit 19 includes a payout belt 15 and also functions as a coin payout path.

  Each coin aligning unit 19 can press the top coin on the payout belt 15 to temporarily stop the coin, and pay out a specified number of coins to the discharged coin receiving unit 23.

  Immediately after each coin aligning unit 19, a payout sensor, which is an optical sensor for counting the number of coins paid out by denomination, is provided.

  Next, the shape of the coin receiving unit 3 will be described in detail. FIG. 4 is an enlarged perspective view showing the coin receiving unit 3 of the coin depositing and dispensing apparatus 1. As shown in FIG. 4, the coin receiving portion 3 includes a pair of left and right side wall portions 3 a and a connecting wall portion 3 b that connects upstream end portions of the pair of left and right side wall portions 3 a. The connecting wall 3b is formed in a curved shape that is recessed toward the upstream side. The connecting wall portion 3 b guides the coins that are in contact with the connecting wall portion 3 b toward the central portion of the receiving belt 5. For example, the connecting wall 3 b guides the standing coin C that has moved upstream along the side wall 3 b toward the center of the receiving belt 5. As a result, coins that are not conveyed while standing in the coin receiving unit 3 are guided toward the center of the receiving belt 5, fall down on the receiving belt 5, and are normally conveyed.

  Here, since the self-checkout terminal 101 is a device operated by a general customer, the coins that are thrown into the payment often have water or dirt or are deformed. Therefore, there is a case where a coin stays in the coin depositing / dispensing apparatus 1 as compared with a case where a store clerk uses the coin. As shown in FIG. 4, many of the coins stay in the receiving unit 3 stand so that the coin C leans against the side wall 3 a of the coin receiving unit 3, and even if the receiving belt 5 rotates forward, It is a phenomenon that cannot be rotated and conveyed. In this case, as will be described later, a retry process is executed to eliminate the stagnation of coins.

  FIG. 5 is a block diagram showing the electrical connection of each unit included in the payment terminal 201. The settlement terminal 201 includes a control unit 253 that controls each unit. The control unit 253 includes a CPU 255 that centrally controls each unit, a ROM 256 that stores fixed data in a fixed manner, a RAM 254 that stores variable data in a rewritable manner, a VRAM 257 that generates a display image to be displayed on the LCD 210, and an HDD 258. Yes. The HDD 258 stores various files such as operation programs, PLU files, image files, audio files, sales files, and the like. All or a part of these operation programs and various files are transferred to the RAM 254 and used when the settlement terminal 201 is activated. In addition to the unit price, the PLU file stores the weight, the lower and upper limit values for the weight, the product display, and the like in a rewritable manner in association with the product code that identifies each product.

  The control unit 253 includes a barcode scanner 204, an LCD 210, a touch panel 211, a receipt printer 251, a card reader / writer 252, a speaker 271, a light emitting unit 218, a coin discriminating device 401, a coin depositing / dispensing device 1, a bill depositing / dispensing device 501, a scale. A communication interface 261 that realizes data communication with the device 301 and an attendant terminal (not shown) for monitoring the plurality of self-checkout terminals 101 is connected via a bus line 259. The control unit 253 controls these units and executes various processes.

  Product sales data processing executed by the control unit 253 of the payment terminal 201 will be described. The merchandise sales data process includes a search process, a weight check process, and a settlement process (see FIG. 8).

  When the barcode attached to the product is read using the barcode scanner 204, the search processing recognizes the product code specified by the read barcode, searches the PLU file, and corresponds to the product code. It is a process which acquires the unit price to perform, weight, and a product display.

  The weight check process determines whether the weight weighed by the scale device 301 after reading the bar code and the weight obtained by the search process are the same as the weight obtained by the search process. This is a process of determining by determining whether or not the value is between the value and the upper limit value.

  The payment process is a process of calculating the total amount that the customer should pay based on the unit price acquired in the search process, and executing the payment of the total amount. The total amount is temporarily registered in the RAM 254 or registered in the sales file. In the settlement process, the calculated total amount can be settled using cash. The handling of cash is executed by the coin deposit / withdrawal apparatus 1 or the banknote deposit / withdrawal apparatus 501.

  FIG. 6 is a block diagram showing an electrical connection of each part provided in the coin depositing and dispensing apparatus 1. The coin deposit / withdrawal apparatus 1 includes a control unit (computer) 30 as an information processing unit that executes information processing. The control unit 30 is responsible for controlling each unit. A POS terminal and a coin discriminating device 401 are connected to the control unit 30 via the communication interface 33. The control unit 30 includes a CPU 30a that centrally controls each unit, a ROM 30b that stores fixed data such as a control program in advance, and a RAM 30c that stores rewritable data such as the number of coins C of denomination. ing.

  In the RAM 30c, a first denomination type file 41 and a second denomination type file 42 for storing the number of coins for each denomination are formed (see FIG. 7).

  The control unit 30 is connected to a receiving sensor 4, a passing sensor 56, a counting sensor 12, sensors 32 including a payout sensor, each motor M, and the like via a bus line 34. The control unit 30 controls driving of each motor M based on the detection output of the sensors 32 and the like.

  FIG. 7 is a schematic diagram showing a data structure of the first denomination type number file 41 and the second denomination type number file 42. The first denomination type number file 41 and the second denomination type number file 42 are formed in the RAM 30c of the coin deposit / withdrawal apparatus 1 for each transaction. As shown in FIG. 7, the first denomination number file 41 and the second denomination number file 42 have data structures that can store the number of coins for each denomination. The first denomination type number file 41 stores the number of coins discharged from the coin discriminating apparatus 401. The number of coins discharged from the coin discriminating apparatus 401 is the number of coins discharged from the coin discriminating apparatus 401 to the coin receiving unit 3 in one transaction. The number of discharged coins is included in the number of discharged coins information transmitted from the coin discriminating apparatus 401 to the control unit 30. In the second denomination number file, the number of coins for each denomination based on the detection output of the counting sensor 12 is stored by the control unit 30. That is, the second denomination type number file stores the number of coins sorted and stored in the sorting and storing unit 57 in one transaction.

  In such a configuration, in the payment terminal 201 of the self-checkout terminal 101, the above-described merchandise sales data processing is executed by the customer.

  FIG. 8 is a flowchart showing a flow of merchandise sales data processing executed by the control unit 253 of the payment terminal 201. First, the customer takes out a product from the shopping basket placed on the basket placing table 102 and causes the barcode scanner 204 to read the barcode. Thereby, the control part 253 of the payment terminal 201 performs a search process (step S101).

  Next, the customer causes the barcode scanner 204 to read the barcode, and then stores the product in a shopping bag held by the scale device 301. A product load is applied to the mounting table 303 a by storing the product in the shopping bag, and an output signal from the load cell unit is input to the settlement terminal 201. Thereby, the control part 253 of the payment terminal 201 performs a weight check process (step S102). When it is determined that the weights are not identical in the weight check process, the execution of the merchandise sales data process is stopped.

  When the customer has finished reading the barcodes for all products desired to be purchased, the customer touches the payment button displayed on the LCD 210 to make a payment using the coin deposit / withdrawal apparatus 1 or the like. Thereby, the control part 253 of the payment terminal 201 performs a payment process (step S103). In the settlement process, the control unit 253 of the settlement terminal 201 displays the calculated total amount on the LCD 210 and displays a message for prompting the insertion of money on the LCD 210. When the customer touches the payment button, it becomes possible to deposit money, so the customer inserts money into the coin insertion unit 402 or the banknote deposit port 503. As described above, the coins input to the coin input unit 402 are input from the coin discriminating device 401 to the coin receiving unit 3 of the coin depositing / dispensing device 1. The coin deposit / withdrawal device 1 and the banknote deposit / withdrawal device 501 transmit the recognized deposit amount to the settlement terminal 201. Then, the control unit 253 makes a settlement if the deposit amount is equal to or greater than the calculated total amount. And when there is change, the control part 253 transmits change data to the coin depositing / withdrawing apparatus 1 and the banknote depositing / withdrawing apparatus 501. The coin deposit / withdrawal device 1 and the banknote deposit / withdrawal device 501 that have received the change data pay out change. More specifically, when a deposit exceeding the total amount is counted by the coin deposit / withdrawal device 1 or the bill deposit / withdrawal device 501, an accounting button is displayed on the LCD 210, and a settlement is possible. Then, when the customer touches the accounting button, the change is paid and the accounting ends.

  Next, the coin receiving process which the control part 30 (CPU30a) of the coin depositing / withdrawing apparatus 1 performs is demonstrated. Here, FIG. 9 is a diagram showing a functional configuration of the coin depositing and dispensing apparatus 1. As shown in FIG. 9, the control unit 30 (CPU 30a) functions as an information reception unit 71, a determination unit 72, and a drive processing unit 73 by following a program.

  The information receiving unit 71 receives the number of discharged coins information indicating the number of discharged coins from the coin discriminating apparatus 401. The information receiving unit 71 stores the received information in the first denomination type number file 41.

  The determination unit 72 determines whether or not coins remain in the coin receiving unit 3 using the detection result of the detection sensor that detects the coins. As an example, a case will be described in which a counting sensor 12 that detects coins sorted in the sorting and storing unit 57 by denomination is used as a detection sensor. In this case, if the number of coins ejected by the coin discriminating apparatus 401 based on the number-of-ejection information does not match the number of coins detected by the counting sensor 12, the determination unit 72 has coins remaining in the coin receiving unit 3. Judge. Specifically, when the number of coins detected by the counting sensor 12 is smaller than the number of coins ejected by the coin discriminating apparatus 401 based on the number-of-ejection information, the determination unit 72 has coins remaining in the coin receiving unit 3. Judge. At this time, the determination unit 72 refers to the first money type number file 41 and the second money type number file 42. The determination unit 72 makes the above determination when the accounting button is touched.

  Another example of the determination by the determination unit 72 will be described. In this example, a receiving sensor 4 that detects a coin in the coin receiving unit 3 is used as a detection sensor. In this case, the determination unit 72 determines that coins remain in the coin receiving unit 3 when the receiving sensor 4 detects the coins for a predetermined time or more.

  As yet another example, the passage sensor 56 may be used as the detection sensor. In this case, when the coin discharge number of the coin discriminating apparatus 401 based on the discharge number information does not match the number of coins detected by the passage sensor 56, the determination unit 72 retains coins in the coin receiving unit 3. Judge that you are doing.

  The drive processing unit 73 controls the motor M to drive the receiving belt 5 forward and backward. When the drive processing unit 73 determines that the coin is discharged (inserted) into the receiving unit 3 based on the detection result of the receiving sensor 4, the drive processing unit 73 causes the receiving belt 5 to roll forward.

  When the determination unit 72 determines that coins remain, the drive processing unit 73 performs a first retry process of rotating the receiving belt 5 in the normal direction after rotating the receiving belt 5 in the reverse direction. If the remaining coins are not eliminated by the retry process, the first retry process is executed again (repetitively executed) with the reverse rotation time of the receiving belt 5 longer than the latest first retry process. For example, when the reverse rotation time of the receiving belt 5 in the first retry process is 1 second, the second time is extended by 1.5 seconds to 2 seconds. Note that increasing the reverse rotation time of the receiving belt 5 is not limited to the first retry processing from the second time onward, but may be the first retry processing from the specified number of times (for example, the third time) onward. That is, after the drive processing unit 73 performs the first retry process for the specified number of times without changing the reverse rotation time of the receiving belt 5, the drive processing unit 73 receives the reverse rotation time compared with the reverse rotation time for the first retry process during the specified number of times. The first retry process may be performed in which the time for reverse rotation of the belt 5 is increased.

  Further, the drive processing unit 73 executes the second retry process when the remaining coins are not eliminated even if the first retry process is performed a specified number of times. The second retry process is a process in which the reverse rotation and the normal rotation of the receiving belt 5 are alternately repeated in a relatively short time.

  Next, the flow of the coin acceptance process will be described with reference to the flowchart of FIG. First, the control unit 30 waits for a coin to be inserted into the coin receiving unit 3 (No in step S201). When it is determined that a coin has been inserted into the coin receiving unit 3 based on the detection result of the receiving sensor 4 (Yes in Step S201), the control unit 30 drives the motor M to cause the receiving belt 5 to roll forward ( Step S202). Thereby, the coins in the receiving unit 3 are conveyed toward the sorting and storing unit 57.

  And when the control part 30 judges that there is no residual coin in the coin receiving part 3 (No of step S203), the drive of the motor M is stopped and the receiving belt 5 is stopped (step S204).

  On the other hand, when the control unit 30 determines that there is a remaining coin in the coin receiving unit 3 (Yes in step S203), the number of retry processes (first retry process) exceeds the specified number N in the current coin receiving process. It is determined whether or not (step S205). Here, the control unit 30 stores the number of executed retry processes in the RAM 30c. Therefore, the control unit 30 can recognize the number of retry processes executed by referring to the RAM 30c. When determining that the number of retry processes does not exceed the prescribed number N (No in step S205), the control unit 30 performs the first retry process (step S206). In the first retry process, for example, after the second time, the reverse rotation time of the receiving belt 5 is made longer than in the previous first retry process. Note that increasing the reverse rotation time of the receiving belt 5 is not limited to the first retry processing from the second time onward, but may be the first retry processing from the specified number of times (for example, the third time) onward. When there is no remaining coin by this process (No in Step S203), the control unit 30 proceeds to Step S204, stops driving the motor M, and stops the receiving belt 5.

  On the other hand, when the control unit 30 determines that the number of retry processes exceeds the specified number N (Yes in step S205), the control unit 30 performs the second retry process (step S207). Then, after the second retry process is executed, if there is no remaining coin (No in Step S208), the control unit 30 proceeds to Step S204, stops driving the motor M, and stops the receiving belt 5. Let If there is a remaining coin even after performing the second retry process (Yes in step S208), the control unit 30 performs an error process (step S209), and then proceeds to step S204 to stop driving the motor M. Then, the receiving belt 5 is stopped. The error process is a process for notifying that there is a residual coin using the LCD 210 or the speaker 271, for example.

  As described above, in the present embodiment, when the determination unit 72 determines that coins remain in the coin receiving unit 3, the drive processing unit 73 rotates the receiving belt 5 in the reverse direction and then moves the receiving belt 5. When the first retry process for forward rotation is executed and the remaining of coins is not eliminated by the first retry process, the reverse rotation time of the receiving belt 5 is set to be longer than that of the most recent first retry process. Run the process again. Accordingly, it is possible to eliminate the stagnation of coins in the receiving unit 3 with higher accuracy.

  Further, in the present embodiment, the determination unit 72 determines whether or not there is a residual coin in the coin receiving unit 3 when the accounting button is touch-operated, and when there is a residual coin, the first retry process is performed. When the first retry process is executed again, the first retry process time is lengthened. As described above, the control for extending the first retry processing time is detected by the detection button such as the counting button 12 and the detection sensor such as the counting sensor 12 when the accounting button is pressed and the number of coins discharged by the coin discriminating apparatus 401 based on the number of discharged sheets It is possible to prevent occurrence of time loss other than when it is necessary only when the number of coins made does not match, that is, when there is a difference in the count between them. There is a high possibility that the deposit is in progress before the accounting button is pressed, and the remaining coins are often washed away at the next coin insertion, and it is more efficient not to extend the reversal time during the retry process. In addition, it is desirable that the first retry process is performed normally until the first and second times, and the reverse rotation time is increased from the third time so as to eliminate time loss as much as possible.

  Moreover, since the accumulation | storage of the coin in the receiving part 3 can be eliminated with higher precision in this way, it is possible to suppress the occurrence of an error in the deposit amount or the occurrence of an error in the coin depositing and dispensing apparatus 1. It is possible to suppress an increase in accounting time.
