  If the money sensor 19 detects that coins and / or bills are placed on the upper surface of the cash tray 17 after the total sales amount is displayed on the display 14 for the operator and the display 15 for the customer, the money detection A signal is output to the control unit 80 (step S5).

  When a currency detection signal is input from the currency sensor 19, the control unit 80 executes a process for calculating the amount received (step S6).

  As shown in FIG. 11, first, the control unit 80 outputs an imaging start signal to the camera 18, and the camera 18 causes the still image on the upper surface of the cash tray 17 to be displayed at a predetermined time interval, for example, every 0.2 seconds. An image is taken (step SA1).

  Still image data captured by the camera 18 at predetermined time intervals is output to the control unit 80 every time it is generated. When still image data is input from the camera 18, the control unit 80 stores the still image data in the fourth memory area 82D of the RAM 82 each time (step SA2).

  At the same time, the control unit 80 stores the reference optical data related to the size, color, and surface pattern of the banknote to be processed and the diameter, color, and hole of the coin type to be processed, stored in the reference data memory area of the ROM 81. Reference optical data relating to the presence / absence is read, and compared with the still image data stored in the fourth memory area 82D of the RAM 82, the denomination of bills and / or coins placed on the upper surface of the cash tray 17 by the customer, and By discriminating the number of sheets, the denomination and number of bills and / or coins placed on the upper surface of the cash tray 17 are stored in the second memory area 82B of the RAM 82 and placed on the upper surface of the cash tray 17. The total amount of bills and / or coins being calculated is calculated and the total amount of bills and / or coins is calculated. Storing the total amount of the second memory area 82B of the RAM 82 (step SA3). At this time, the control unit 80 displays the total amount of bills and / or coins placed on the upper surface of the cash tray 17 on the operator display 14 and the customer display 15.

  Here, the control unit 80 calculates the denomination and number of banknotes and / or coins based on the still image data captured by the camera 18 as follows, for example.

  FIG. 12 shows a still image captured by the camera 18 when three coins are placed on the upper surface of the cash tray 17 so as not to overlap each other.

  As shown in FIG. 12, the still image includes the cash tray 17 and three coin images (pixel aggregates) 120, 121, and 122 placed so as not to overlap each other. .

  When the customer places the coins on the upper surface of the cash tray 17 so as not to overlap, the control unit 80 determines that the coins are placed on the upper surface of the cash tray 17 as follows, The number and amount of coins placed on the upper surface of the cash tray 17 can be calculated.

  First, the control unit 80 compares the previous still image obtained by imaging the cash tray 17 on which no coins or banknotes are placed with the next captured still image (step SA4).

  As a result, when it is determined that the pattern of the still image data captured last time is different from the still image data captured this time, the control unit 80 determines the number of coins placed on the upper surface of the cash tray 17.

  First, the control unit 80 compares the previous still image obtained by imaging the cash tray 17 on which no coins or banknotes are placed with the next captured still image (step SA4).

  As a result, when it is determined that the pattern of the still image data captured last time is different from the still image data captured this time, the control unit 80 determines the number of coins placed on the upper surface of the cash tray 17. Start the calculation process of the amount.

  At this time, the three coins are placed on the upper surface of the cash tray 17 so as not to overlap each other, and the still image captured this time is on the cash tray 17 as shown in FIG. Three coin images (pixel aggregates) 120, 121, and 122 including a plurality of pixels are included.

  When the money placed on the cash tray 17 is a coin, the pixels 120A, 120B, 120C, 120D... 120N, 121A, 121B, 121C, 121D. Since the distances from 121N, 122A, 122B, 122C,... 122N are close to each other, the control unit 80 can detect the pixels 120A, 120B, 120C, 120D,. 121B, 121C, 121D... 121N, 122A, 122B, 122C... 122N are determined to be coins when the coins placed on the cash tray 17 are close to each other. These distances are doubled to calculate the diameters of the pixel aggregates 120, 121, and 122.

  Next, the control unit 80 reads the reference optical data regarding the diameter, color and presence / absence of the coin type to be processed stored in the reference data memory area of the ROM 81, and the diameter of the coin thus obtained is determined. The denomination of the coin is determined by comparing the data with the reference diameter data of the coin of each denomination.

  Of the inclination angle data of the line segment connecting two adjacent pixels of each set of peripheral edges obtained in this way, the inclination angle data with different inclination angles is read, and the inclination angle data with different inclination angles is read. When the number is less than the first threshold value, the control unit 80 determines that the pixel aggregate 130 defined by the peripheral pixels is the banknote image 130.

  When it is determined that the image defined by the peripheral pixels 130A, 130B, 130C, 130D,... Is the banknote image 130, the control unit 80 determines the coordinate points of the two sets of two pixels thus obtained. The average value of the inclination angles with the inclination angle difference equal to or less than the second threshold value is calculated by the inclination angle of the line segment connecting the two pixels, and between the peripheral pixels along the straight line whose inclination angle is equal to the average value The distance is obtained, the maximum distance D1 between the peripheral pixels is obtained, the distance between the peripheral pixels along the straight line having an angle orthogonal to the average value of the inclination angles thus obtained is obtained, and the peripheral pixels are obtained.

  When one bill is placed on the upper surface of the cash tray 17 by the customer, it can be determined that the money placed on the upper surface of the cash tray 17 is a bill as follows.

  FIG. 13 shows a still image captured by the camera 18 when a banknote is placed on the upper surface of the cash tray 17. The still image includes a plurality of pixels on the upper surface of the cash tray 17. A banknote image (pixel aggregate) 130 is included.

  First, in the same way as when the coin placed on the upper surface of the cash tray 17 is a coin, the control unit 80 detects the pixels 130 </ b> A, 130 </ b> B, 130 </ b> C at the peripheral edge of the banknote image (pixel aggregate) 130. , 130N is selected.

  Next, the control unit 80 obtains the distance between each pair of pixels by combining the two pixels 130A, 130B, 130C,..., 130N constituting the peripheral portion of the pixel assembly 130 thus selected. When the distance between the pixels of all the sets is equal to or greater than the second predetermined value, for example, 70 mm, it is tentatively determined that the currency placed on the cash tray 17 is a banknote.

  On the other hand, the two pixels 130A, 130B, 130C,..., 130N constituting the peripheral portion of the money image (pixel aggregate) 130 are set as one set, and the distance between each set of pixels is obtained. When the distances between all the pairs of pixels are equal to or less than a first predetermined value, for example, 30 mm or less, it is tentatively determined that the currency placed on the cash tray 17 is a coin.

  When it is tentatively determined that the money placed on the cash tray 17 is a banknote, the control unit 80 selects two pixels at adjacent peripheral edges as a set of pixels, and adjacent to the peripheral edge. An inclination angle data is generated by calculating an inclination angle of a line segment connecting a pair of matching pixels. Similarly, the inclination angle data is generated by calculating the inclination angle of each line segment connecting a plurality of sets of pixels.

  Of the inclination angle data of the line segment connecting two adjacent pixels of each set of peripheral edges generated in this way, the inclination angle data with different inclination angles is read, and the inclination angle data with different inclination angles is read.

An average value of the inclination angles of the inclination angle data having different numbers of inclination angles is calculated, and it is determined that the obtained inclination angle coincides with the longitudinal direction of the bill.

  On the other hand, when the number of inclination angle data having different inclination angles is equal to or larger than the second threshold value, the control unit 80 indicates that the image defined by the peripheral pixels is a coin image 130. It is temporarily determined that there is.

  Further, the control unit 80 calculates the distance between the peripheral pixels located in the longitudinal direction, determines the length in the longitudinal direction of the banknote, and determines the cash tray 17 based on the length in the longitudinal direction of the banknote. It is tentatively determined that the money placed on the top is a banknote.

  Next, the control unit 80 compares the reference optical data of the banknote regarding the color and surface pattern of the banknote with the data about the color and surface pattern of the banknote read from the banknote image 130 defined by the peripheral edge, and The denomination is finally determined.

  As shown in FIG. 14, the still image includes three banknote images 130, 131, and 132 superimposed on the upper surface of the cash tray 17 while being shifted from each other.

  In such a case, the denomination of the banknote 130 stacked on top can be determined as described with reference to FIG.

  The denomination of the banknote 131 stacked second from the top and the denomination of the banknote 132 stacked third represent the face value printed on the corner of the banknote based on the reference optical data of the banknote regarding the surface pattern. It can be determined by detecting numbers and colors.

  FIG. 15 shows a still image captured by the camera 18 when a coin is placed on the upper surface of one banknote 130 placed on the upper surface of the cash tray 17.

  In this case, by comparing the still image immediately before the coin 120 is placed on the upper surface of the banknote 130 with the still image shown in FIG. 15, the method described with reference to FIG. The denomination of the coin placed in can be discriminated.

  Specifically, when the control unit 80 determines the denominations of bills and / or coins placed on the upper surface of the cash tray 17, first, the control unit 80 determines a large number of pixels corresponding to the peripheral portion, Based on the distance between the pixels corresponding to the section and the inclination angle between the pixels, it is determined whether the money placed on the upper surface of the cash tray 17 is a banknote or a coin. Calculate the denomination and number of coins.

  Similarly, a still image on the upper surface of the cash tray 17 is captured at a predetermined time interval by the camera 18 to generate still image data (step SA1), and the generated still image data is sent to the control unit 80. Is output.

  When still image data is input from the camera 18, the control unit 80 stores the still image data in the fourth memory area 82D of the RAM 82 (step SA2).

  At the same time, the control unit 80 stores the reference optical data regarding the size, color and surface pattern of the banknote to be processed and the diameter, color and hole of the coin type to be processed, stored in the reference data memory area of the ROM 81. Reference optical data relating to the presence / absence is read out and compared with the pattern of banknotes and / or coins placed on the cash tray 17 stored in the fourth memory area 82D of the RAM 82, by the customer on the upper surface of the cash tray 17 The denomination and number of bills and / or coins placed are discriminated, and the denomination and number of bills and / or coins placed on the upper surface of the cash tray 17 in the second memory area 82B of the RAM 82. And / or banknotes placed on the upper surface of the cash tray 17 and / or Calculate the total amount of currency, storing the total value of the total amount and / or coins banknotes in the second memory area 82B of the RAM 82 (step SA3).

  The control unit 80 captures the image of the banknotes and / or coins placed on the cash tray 17 stored in the fourth memory area 82D of the RAM 82, and the image of the RAM 82 by the camera 18 during the previous imaging. The still image data pattern stored in the fourth memory area 82D is compared to determine whether the still image data pattern is different from the previous still image data pattern (step SA4).

  As a result, when the pattern of the still image data is different from the pattern of the previous still image data, the control unit 80 accesses the second memory area 82B of the RAM 82 and the cash tray by the customer at the previous imaging. It is determined whether or not the money placed on the upper surface of 17 is only a coin (step SA5).

  If the coin placed on the top surface of the cash tray 17 was only a coin at the time of the previous imaging, still image data generated by the camera 18 and stored in the fourth memory area 82D of the RAM 82 this time. Based on the above, it is determined whether or not the money placed on the upper surface of the cash tray 17 is only a coin even during the current imaging (step SA6).

  As a result, when it is determined that the money placed on the upper surface of the cash tray 17 is only a coin at the time of the current image capture, the customer can use the cash tray between the previous image capture time and the current image capture time. A coin is further added to the coin placed on the upper surface of the cash tray 17 on the upper surface of the cash tray 17, a coin placed on the upper surface of the cash tray 17 is replaced with a higher price coin, or the cash tray It is thought that some coins were removed because coins exceeding the trading value were placed on the upper surface of 17.

  Therefore, the control unit 80 calculates the denomination and number of coins and the total amount of coins based on the still image data generated by the current imaging, and writes them in the second memory area 82B of the RAM 82 (step SA7). ). At the same time, the control unit 80 displays the total amount of coins on the operator display 14 and the customer display 15.

  On the other hand, when it is not only coins that are placed on the upper surface of the cash tray 17 at the time of this imaging, the previous time when only coins were placed on the upper surface of the cash tray 17 Since the customer placed the banknote on the upper surface of the cash tray 17 between the time of imaging and the time of the current imaging, it is considered that the banknote was placed on the coin placed on the upper surface of the cash tray 17. The control unit 80 calculates the denomination and number of banknotes and the total amount of banknotes based on the still image data generated by the current imaging, and writes them in the second memory area 82B of the RAM 82 (step SA8). . At the same time, the control unit 80 reads the total amount of coins written in the second memory area 82B of the RAM 82, adds them up, and puts the total amount of bills and coins on the display 14 for the operator and the display 15 for the customer. indicate.

  On the other hand, when it is determined that it is not only coins that are placed on the upper surface of the cash tray 17 at the previous imaging (step SA5), the control unit 80 controls the upper surface of the cash tray 17 at the previous imaging. It is determined whether or not it is only a bill that is placed on (step SA9).

  As a result, when it is determined that only the banknote is placed on the upper surface of the cash tray 17 at the previous imaging, the control unit 80 further controls the upper surface of the cash tray 17 at the current imaging. It is determined whether or not only the banknote is placed (step SA10).

  As a result, when it is determined that only the banknote is placed on the upper surface of the cash tray 17 at the time of the current imaging, only the banknote is placed on the upper surface of the cash tray 17 during the previous imaging. Since the customer added the banknote on the top surface of the cash tray 17 or removed a part of it or exchanged it for a banknote of a different denomination between the time and the current imaging, the control unit 80 Based on the still image data generated by the current imaging, the denomination and number of banknotes and the total amount of banknotes are calculated and written in the second memory area 82B of the RAM 82 (step SA11). At the same time, the control unit 80 displays the total amount of bills on the operator display 14 and the customer display 15.

  On the other hand, when it is determined that it is not only the banknote that is placed on the upper surface of the cash tray 17 at the time of the current imaging, the cash tray 17 is set by the customer between the previous imaging time and the current imaging time. Since the coin is considered to have been placed on the banknote placed on the upper surface, the control unit 80 determines the denomination and number of coins and the total amount of coins based on the still image data generated by the current imaging. Is calculated and written to the second memory area 82B of the RAM 82 (step SA12). At the same time, the control unit 80 reads the total amount of banknotes written in the second memory area 82B of the RAM 82, adds them up, and adds the total amount of banknotes and coins to the operator display 14 and the customer display 15. indicate.

  On the other hand, when it is determined that it is not only the bill that is placed on the upper surface of the cash tray 17 at the time of the previous imaging, only the coin is placed on the upper surface of the cash tray 17. Therefore, the bills and coins are placed on the top surface of the cash tray 17, and the bills and coins are placed on the top surface of the cash tray 17 even during the current imaging. When banknotes and coins are placed on the upper surface of the cash tray 17, usually coins are placed on the banknotes.

  Therefore, the control unit 80 compares the pattern of the still image data captured last time with the pattern of the still image data captured this time, and the cache tray 17 between the previous imaging time and the current imaging time. It is determined whether it is a bill or a coin that is placed on the top surface of the bill (step SA13). When it is determined that the bill is a bill, the bill is based on the still image data generated by the current imaging. Are calculated and written in the second memory area 82B of the RAM 82 (step SA14). At the same time, the control unit 80 reads the total amount of banknotes and coins written in the second memory area 82B of the RAM 82, and displays the total amount of banknotes and coins on the display 14 for the operator and the display 15 for the customer. To do.

  On the other hand, when it is determined that the coin was added or placed on the top surface of the cash tray 17 between the previous imaging and the current imaging, Based on the still image data generated by the imaging, the denomination and number of coins and the total amount of coins are newly calculated and written in the second memory area 82B of the RAM 82 (step SA15). At the same time, the control unit 80 reads out the new total amount obtained by adding the newly calculated amount of coins to the total amount of bills and coins written in the second memory area 82B of the RAM 82, and displays it for the operator. 14 and the display 15 for customers display the total amount of bills and coins.

  When the above process is repeatedly executed at predetermined time intervals and the customer determines that the payment of the trading price has been completed, the operator inputs a received amount confirmation signal that instructs the touch panel 13 to confirm the received amount. (Step SA16).

  At this time, when the operator determines that there is an error in the amount received from the customer calculated based on the still image data of the banknote and / or coin taken by the camera 18, the amount received from the customer is corrected. A received money amount correction signal is input to the touch panel 13 and a correct received money amount is input to the touch panel 13. The received amount correction signal and the correct received amount data input to the touch panel 13 are input to the control unit 80. When the received amount correction signal and the correct received amount data are received, the control unit 80 stores in the second memory area 82B of the RAM 82. Rewrite the stored amount received from customers.

  The operator inputs a received amount confirmation signal to the touch panel 13 after inputting the received amount correction signal and the correct received amount to the touch panel 13.

  The received amount confirmation signal is output to the control unit 80. When the control unit 80 receives the received amount confirmation signal, the total amount of bills and / or coins stored in the second memory area 82B is determined as the received amount, The received amount is displayed on the operator display 14 and the customer display 15 (step S7).

  The control unit 80 further calculates the amount of change by comparing the data relating to the received amount thus determined with the data relating to the buying and selling amount of the product purchased by the customer stored in the first memory area 82A of the RAM 82. The change amount is displayed on the display 14 for the operator and the display 15 for the customer, and the number of banknotes to be paid to the customer as change and / or the denomination and the number of coins are determined. The third memory area 82C is written (step S8).

  Next, the control unit 80 specifies the number of types of coins to be dispensed and outputs a withdrawal instruction signal to the second controller 100 of the coin depositing and dispensing mechanism 22 of the coin depositing and dispensing machine 20. The number of banknotes to be withdrawn is specified to the third controller 110 of the banknote dispensing mechanism 23 of the money machine 20, and a withdrawal instruction signal is output. Here, the banknote dispensing mechanism 23 is configured to withdraw only 1000 yen banknotes in the case of banknotes of denominations that are most frequently used as change, Japanese banknotes, and therefore, the control unit 80. Is configured to instruct the third controller 110 of the banknote dispensing mechanism 23 to specify only the number of banknotes to be dispensed and to dispense as change.

  When receiving the withdrawal instruction signal from the control unit 80 of the POS terminal device 1, the second controller 100 of the coin depositing / dispensing mechanism 22 recognizes the coin according to the number of coins to be dispensed specified by the control unit 80. A drive signal is selectively output to the feeding mechanisms 63A, 63B, 63C, 63D, 63E, and 63F, and a drive signal is output to the fifth motor 107, so that the coin storage cylinders 60A, 60B, 60C, 60D, 60E, The coins stored in the 60F are selectively fed out one by one onto the coin dispensing endless belt 64.

  Coins fed on the coin dispensing endless belt 64 are guided to the coin dispensing port 65 by the guide plate 66 and dispensed as coins for change.

  On the other hand, when the withdrawal instruction signal is received from the control unit 80 of the POS terminal device 1, the third controller 110 of the banknote dispensing mechanism 23 changes the number according to the number of banknotes to be dispensed specified by the control unit 80. Drive signals are output to the sixth motor 114, the seventh motor 115, the eighth motor 116, and the ninth motor 117.

  As a result, among the banknotes placed on the withdrawal banknote placement plate 74 of the withdrawal banknote storage box 70, the banknote located at the top is kicked out by the kicking roller 75 toward the feeding roller 76. The banknote kicked out by the kicking roller 75 is fed into the dispensing banknote transport path 71 by the feeding roller 76. At this time, the separation roller 77 prevents two or more banknotes from being fed into the withdrawal banknote transport path 71, and banknotes are fed into the withdrawal banknote transport path 71 one by one. By 78 and 79, the inside of the withdrawal banknote conveyance path 71 is conveyed and withdrawn to the banknote withdrawal port 72 as a banknote for change.

  The withdrawal bill transport path 71 is provided with a withdrawal bill sensor 113 that counts the number of bills to be dispensed, and every time a bill to be dispensed is detected, the withdrawal bill sensor 113 controls the third controller. A withdrawal bill detection signal is output to 110, and the third controller 110 counts the number of dispensed bills based on the withdrawal bill detection signal input from the withdrawal bill sensor 113, and a POS terminal device. If it is determined that the number of banknotes instructed from the first control unit 80 is withdrawn, a drive stop signal is sent to the sixth motor 114, the seventh motor 115, the eighth motor 116, and the ninth motor 117. Output, and the withdrawal of banknotes is completed.

  The bills and / or coins withdrawn in this manner are delivered to the customer by the operator as change.

  If it is determined that the result of automatic calculation of the received amount up to step SA15 is correct and the operator immediately inputs a received amount confirmation signal to the touch panel 13, the customer delivers the change to the customer, and then the customer cashes the transaction price. The cash placed on the tray 17 is removed by the operator and deposited into the money depositing / dispensing machine 20.

  On the other hand, when the operator determines that the result of automatic calculation of the amount received up to step SA15 is not correct, the operator places the cash placed on the cash tray 17 as a trading value and reconfirms it. After that, the correct receipt amount is input to the touch panel 13. Therefore, banknotes and / or coins from the customer placed by the operator are handed over to the customer and then deposited into the money depositing / dispensing machine 20 by the operator.

  When depositing banknotes received from a customer, the banknotes are inserted one by one into the banknote deposit port 30 by the operator, and the banknotes are detected by the banknote sensor 93.

  The banknote sensor 93 outputs a banknote detection signal to the first controller 90 when it detects a banknote inserted into the banknote deposit slot 30.

  Upon receipt of the bill detection signal, the first controller 90 outputs a first drive signal to the first motor 94, rotates the pair of endless belts 31, 32 in the forward direction, and drives the gear 38. A drive signal is output to the second motor 95.

  As a result, the banknotes are transported in the deposited banknote transport path 33 by the pair of endless belts 31, 32, and the optical data and magnetic data of the banknotes are detected by the deposited banknote sensor 34. The optical data and magnetic data of the bill are output from the deposited bill sensor 34 to the first controller 90.

  When receiving the optical data and magnetic data of the banknote from the deposited banknote sensor 34, the first controller 90 accesses the ROM 91 to read the optical standard data and magnetic standard data of the money type of the banknote, In contrast to the optical data and magnetic data of the banknote input from the sensor 34, the banknote detected by the deposited banknote sensor 34 is genuinely receivable or cannot be received such as counterfeit banknotes in a known manner. Determine if it is a banknote.

  As a result, when it is determined that the banknote detected by the deposited banknote sensor 34 is an unreceivable banknote such as a counterfeit banknote, the first controller 90 outputs a second drive signal to the first motor 94. The pair of endless belts 31 and 32 are rotated in the opposite directions to return the banknotes to the banknote deposit slot 30 and unreceivable banknotes are detected in the memory area for storing information on the authenticity of the deposited banknotes in the RAM 92. Record the information to the effect.

  On the other hand, when it is determined that the banknote detected by the deposited banknote sensor 34 is a genuinely receivable banknote, the first controller 90 simultaneously determines the denomination of the banknote and the denomination of the RAM 92. The number of deposited banknotes written in the memory area for storing data relating to the banknotes is increased by one.

  Further, the first controller 90 drives the pair of endless belts 31 and 32 to place the bills on the guide member 36 of the deposit bill storage box 35 and outputs a drive signal to the second motor 95. Then, the gear 38 is driven to rotate.

  As a result, when the pusher 39 is moved downward and passes through an opening (not shown) of the guide member 36, the deposited banknote supported by the guide member 36 is pushed toward the deposited banknote placement plate 37, and the deposited banknote It is mounted on the mounting plate 37.

  At this time, the deposited bill placement plate 37 is lowered by a distance corresponding to the thickness of the bill against the biasing force of the biasing means 40 such as a spring.

  Thus, the banknotes received from the customer are deposited in the deposit banknote storage box 35 of the banknote deposit mechanism 21 of the money depositing / dispensing machine 20, and the total amount of the deposited banknotes is stored in a memory area for storing data on the deposited banknotes in the RAM 92. Written.

  On the other hand, when depositing coins received from a customer, a plurality of coins are inserted into the coin deposit port 50 by the operator.

  As a result, the coin sensor 103 detects that a coin has been inserted into the coin deposit port 50, and a coin detection signal is output to the second controller 100.

  When receiving the coin detection signal from the coin sensor 103, the second controller 100 outputs a drive signal to the rotating disk motor 104 to rotate the rotating disk 52.

  As a result, the coins inserted into the coin deposit port 50 fall onto the upper surface of the rotating rotating disk 52 and are sent out one by one to the deposited coin transport path 51 by the centrifugal force generated by the rotation.

  When the coin detection signal is output to the second controller 100, the second controller 100 simultaneously outputs a drive signal to the third motor 105 to drive the endless belt 53 provided in the deposit coin transport path 51. To do.

  Thus, when the coin is transported through the deposit coin transport path 51 by the endless belt 53 and reaches the deposit coin sensor 54, the deposit coin sensor 54 detects and detects the optical data and magnetic data of the deposit coin. The optical data and magnetic data of the deposited coin are output to the second controller 100.

  When receiving the optical data and magnetic data of the received coin, the second controller 100 accesses the ROM 101 to read out the optical reference data and magnetic reference data of the coin money type and input from the received coin sensor 54. In comparison with the optical data and magnetic data of the received coin, it is determined whether the coin detected by the deposited coin sensor 54 is a genuine coin that can be received or a coin that cannot be received such as a counterfeit coin. To do.

  As a result, when it is determined that the coin is an unacceptable coin such as a counterfeit coin, an unacceptable coin storage box (not shown) is inserted from the unacceptable coin recovery port 55 provided on the downstream side of the deposit coin sensor 54. To be recovered.

  On the other hand, when the second controller 100 determines that the coin can be accepted, the denomination and the number of the received coins are stored in the memory area for storing the received coin data in the RAM 102.

  The coins are further transported in the deposit coin transport path 51 and sent to the coin sorting passage 57 via the bent portion 56.

  When the coin detection signal is output to the second controller 100, the second controller 100 simultaneously outputs a drive signal to the fourth motor 106, and a pair of endless belts 61 provided in the coin sorting passage 57, 62 is driven.

  As a result, the deposited coin is conveyed toward the downstream side along the reference rail 58 in the coin sorting passage 57 by the pair of endless belts 61 and 62.

  The coin sorting passage 57 is formed with coin sorting ports 59A, 59B, 59C, 59D, 59E, and 59F for dropping coins according to denomination along the reference rail 58 and forming the most of the coin sorting passage 57. The diameter of the coin sorting port 59A located on the upstream side is such that, among the coins to be processed, the coin with the smallest diameter falls, but the coin with the second smallest diameter does not fall. The diameter of the coin sorting port 59B is such that the coin with the second smallest diameter falls, but the coin with the third smallest diameter does not fall, and the diameter of the coin sorting port 59C is 3 The coin with the fourth smallest diameter will fall, but the coin with the fourth smallest diameter will not fall, and the diameter of the coin sorting port 59D will be the coin with the fourth smallest diameter. Will fall, but the fifth smallest coin will not fall The diameter of the coin sorting port 59E located on the most downstream side of the coin sorting passage 57 is such that the coin with the fifth smallest diameter falls, but the coin with the largest diameter does not fall. In addition, the diameter of the coin sorting port 59F is set to such a diameter that the coin of the denomination of the maximum diameter falls.

  Accordingly, among the coins to be processed, only the coin with the smallest diameter is selected from the coin sorting port 59A formed on the most upstream side of the coin sorting passage 57, and only the coin with the second smallest diameter is selected. From the mouth 59B, only the coin with the third smallest diameter is from the coin sorting slot 59C, and only the coin with the fourth smallest diameter is from the coin sorting slot 59D, and the coin with the fifth smallest diameter is the coin. Only the coins from the coin sorting port 59E fall and the coins with the largest diameter fall from the coin sorting port 59F. Therefore, among the coins to be processed, the coin with the smallest diameter is the second in the coin storage cylinder 60A. Coins of a denomination with the smallest diameter are in the coin storage cylinder 60B, coins of a denomination with the third smallest diameter are in the coin storage cylinder 60C, and coins of a denomination with the fourth smallest diameter are in the coin storage cylinder 60D. In addition, the fifth smallest denomination coin is stored In 60E, the maximum diameter of the coin is housed in the coin storing cylinder 60F.

  Thus, banknotes and / or coins received from the customer are deposited into the money depositing / dispensing machine 20.

  According to the present embodiment, the amount of cash received by the customer on the top surface of the cash tray 17 as the purchase price of the product is imaged by the camera 18 at the predetermined time interval on the top surface of the cash tray 17. , Generating still image data of banknotes and / or coins placed on the upper surface of the cash tray 17, optical reference data about the size, color, surface pattern of the banknote denomination and / or diameter of the coin denomination, Since it is configured to be determined by discriminating the denomination and the number of bills and / or coins placed on the upper surface of the cash tray 17 in comparison with the optical reference data on the presence / absence of holes and colors. , The operator does not have to determine the amount received from the customer at his own risk, thus reducing the operator's mental burden Bets can be, after receipt amount is determined, because immediately change is paid, it takes a long time to pay the change, it is possible to reliably prevent the to waste time to the customer.

  FIG. 16 is a schematic perspective view of a POS terminal device 1 according to another preferred embodiment of the present invention.

  As shown in FIG. 16, in the POS terminal device 1 according to another preferred embodiment of the present invention, the camera 18 that is an imaging device includes not only the upper surface of the cash tray 17 but also the peripheral region on the upper surface of the cash tray 17. It is configured to be capable of imaging.

  As shown in FIG. 6, also in this embodiment, the RAM 82 stores a first memory area 82 </ b> A that stores data related to the purchase / purchase amount of the product purchased by the customer, and a first memory region 82 </ b> A that stores data related to the received amount received from the customer. A second memory area 82B, a third memory area 82C for storing data relating to the amount of change to be paid to the customer, and a fourth memory area 82D for storing still image data of bills and / or coins captured by the camera 18. I have.

  FIG. 17 is a subroutine showing a received money amount calculation process executed in the POS terminal apparatus 1 according to another preferred embodiment of the present invention configured as described above.

  Also in the POS terminal device 1 according to the present embodiment, according to the flowchart shown in FIG. 10, the purchase price is received from the customer, and the change is calculated.

  First, the operator causes the barcode reader 11 to read a barcode (not shown) attached to the product, so that the transaction price data of the product that the customer intends to purchase is read into the POS terminal device 1 (step S1). ) When the barcode reader 11 reads a barcode (not shown) attached to the product, the sale price data is output from the barcode reader 11 to the control unit 80 each time.

  When the control unit 80 receives the transaction amount data from the barcode reader 11, the control unit 80 writes the transaction amount data for each product in the first memory area 82A that stores data related to the transaction amount of the product purchased by the customer in the RAM 82. Each time, the total amount is calculated and written to the first memory area 82A of the RAM 82 (step S2), and the sales amount for each product and the total sales amount are displayed on the display 14 for the operator and the display 15 for the customer. .

  When the input of the transaction price data of all the products purchased by the customer is completed, the operator inputs to the touch panel 13 that the input of the transaction price data of the products is completed (step S3).

  When it is input to the touch panel 13 that the input of the sales amount data of the product is completed, a sales amount data input completion signal is output from the touch panel 13 to the control unit 80, and the control unit 80 receives the sales amount data input completion signal. The total sales amount written in the first memory area 82A of the RAM 82 is displayed on the operator display 14 and the customer display 15 as the total sales amount of the products purchased by the customer (step S4).

  If the money sensor 19 detects that coins and / or bills are placed on the upper surface of the cash tray 17 after the total sales amount is displayed on the display 14 for the operator and the display 15 for the customer, the money detection A signal is output to the control unit 80 (step S5).

  When a currency detection signal is input from the currency sensor 19, the control unit 80 starts a received amount calculation process.

  First, the control unit 80 outputs an imaging start signal to the camera 18, and the camera 18 captures still images on the upper surface of the cash tray 17 at predetermined time intervals (step SB1).

  Still image data captured by the camera 18 at predetermined time intervals is output to the control unit 80 every time it is generated. When still image data is input from the camera 18, the control unit 80 writes the still image data in the fourth memory area 82 </ b> D of the RAM 82. At this time, the control unit 80 determines whether or not a hand is shown in the peripheral area of the cash tray 17 based on the still image data input from the camera 18 (step SB2).

  As a result, when it is determined that the hand is not shown in the peripheral area of the still image cache tray 17, the control unit 80 converts the still image data into the fourth memory area of the RAM 82 in the form of an image pattern each time. 82D is stored (step SB3).

  At the same time, the control unit 80 stores the reference optical data regarding the size, color and surface pattern of the banknote to be processed and the diameter, color and hole of the coin type to be processed, stored in the reference data memory area of the ROM 81. Reference optical data relating to the presence / absence is read out and compared with the pattern of banknotes and / or coins placed on the cash tray 17 stored in the fourth memory area 82D of the RAM 82, by the customer on the upper surface of the cash tray 17 The denomination and number of bills and / or coins placed are discriminated, and the denomination and number of bills and / or coins placed on the upper surface of the cash tray 17 in the second memory area 82B of the RAM 82. And / or banknotes placed on the upper surface of the cash tray 17 and / or Calculate the total amount of currency, storing the total value of the total amount and / or coins banknotes in the second memory area 82B of the RAM 82 (step SB4).

  On the other hand, when it is determined that the hand is in the still image, the control unit 80 determines whether the hand is the customer's hand or the operator's hand (step SB5).

  Here, whether the hand moving to the still image belongs to the customer or the operator can be determined by determining the direction in which the hand extends.

  As a result, when it is determined that the hand shown in the still image is the customer's hand, the customer adds banknotes and / or coins to the upper surface of the cash tray 17 or is placed on the upper surface of the cash tray 17. In order to remove a part of the bills and / or coins that have been used, or to replace the bills and / or coins placed on the top surface of the cash tray 17 with bills and / or coins of other denominations This is a normal action for paying the trading value, so that the process proceeds to step SB3 and the same processing as when the hand is not shown in the still image is executed. .

  On the other hand, when it is determined that the hand shown in the still image is the hand of the operator, the control unit 80 determines the receipt amount of the banknotes and / or coins placed on the cash tray 17 by the customer, Since the POS terminal device 1 may not be able to automatically perform calculation processing, the operator is reaching out to confirm the banknotes and / or coins placed on the upper surface of the cash tray 17 by the customer. Judge.

  Therefore, when the operator's hand extends toward the cash tray 17, the calculation is performed based on the still image data generated at the previous imaging, that is, at the imaging before the operator reaches the cash tray 17. Since it is efficient to keep the denomination and number of banknotes and / or coins and the total amount on the cash tray 17 written in the second memory area 82B of the RAM 82 as they are, the control unit 80 Does not write still image data picked up after the operator reaches for the cash tray 17 in the fourth memory area 82D of the RAM 82, but invalidates it (step SB6).

  If the received amount of the banknote and / or coin confirmed by the hand matches the received amount from the customer calculated based on the still image data of the banknote and / or coin imaged by the camera 18, Immediately, a received amount confirmation signal is input to the touch panel 13 to instruct that the received amount should be confirmed. On the other hand, when it is determined that there is an error in the amount received from the customer calculated based on the still image data of the banknote and / or coin taken by the camera 18, the amount received from the customer is corrected. The received amount correction signal is input to the touch panel 13, and after the correct received amount is input to the touch panel 13, a received amount confirmation signal is input to the touch panel 13 (step SB20).

  When the still image data is stored in the fourth memory area 82D of the RAM 82 in the form of an image pattern, the control unit 80 is placed on the cache tray 17 stored in the fourth memory area 82D of the RAM 82. The pattern of the bills and / or coins that have been captured is compared with the pattern of the still image data captured and input by the camera 18 and stored in the fourth memory area 82D of the RAM 82 at the time of the previous imaging, It is determined whether or not the current still image data pattern is different from the previous still image data pattern (step SB7).

  As a result, when the pattern of the still image data is different from the pattern of the previous still image data, the control unit 80 accesses the fourth memory area 82D of the RAM 82, and the cash tray is set by the customer at the previous imaging. It is determined whether or not the currency placed on the upper surface of 17 is only a coin (step SB8).

  When it is determined that the money placed on the upper surface of the cash tray 17 was only a coin during the previous imaging, the still image generated by the camera 18 and stored in the fourth memory area 82D of the RAM 82 this time. Based on the data, it is determined whether or not the money placed on the upper surface of the cash tray 17 is only a coin even during the current imaging (step SB9).

  As a result, when it is determined that the money placed on the upper surface of the cash tray 17 is only a coin at the time of the current image capture, the customer can use the cash tray between the previous image capture time and the current image capture time. A coin is further added to the coin placed on the upper surface of the cash tray 17 on the upper surface of the cash tray 17, a coin placed on the upper surface of the cash tray 17 is replaced with a higher price coin, or the cash tray It is considered that some coins were removed because coins exceeding the trading value were placed on the upper surface of 17.

  Therefore, the control unit 80 calculates the denomination and number of coins and the total amount of coins based on the still image data generated by the current imaging, and writes them in the second memory area 82B of the RAM 82 (step SB10). ). At the same time, the control unit 80 displays the total amount of coins on the operator display 14 and the customer display 15.

  On the other hand, what is placed on the upper surface of the cash tray 17 at the time of imaging this time is not only a coin but is placed on the upper surface of the cash tray 17 when a banknote is reflected. The customer places the banknote on the upper surface of the cash tray 17 between the previous imaging and the current imaging, which is only a coin, and the banknote is placed on the coin placed on the upper surface of the cash tray 17. Therefore, the control unit 80 calculates the denomination and number of banknotes and the total amount of banknotes based on the still image data generated by the current imaging, and the second memory area of the RAM 82 Write to 82B (step SB11). At the same time, the control unit 80 reads the total amount of coins written in the second memory area 82B of the RAM 82, adds them up, and puts the total amount of bills and coins on the display 14 for the operator and the display 15 for the customer. indicate.

  On the other hand, when it is determined that it is not only coins that are placed on the upper surface of the cash tray 17 at the previous imaging (step SB8), the control unit 80 controls the upper surface of the cash tray 17 at the previous imaging. It is determined whether or not it is only a bill that is placed on (step SB12).

  As a result, when it is determined that only the banknote is placed on the upper surface of the cash tray 17 at the previous imaging, the control unit 80 further controls the upper surface of the cash tray 17 at the current imaging. It is determined whether or not only the bill is placed (step SB13).

  As a result of the determination, when it is determined that only the banknote is placed on the upper surface of the cash tray 17 at the time of the current imaging, the control unit 80 is based on the still image data generated by the current imaging. Then, the denomination and number of banknotes and the total amount of banknotes are calculated and written in the second memory area 82B of the RAM 82 (step SB14). At the same time, the control unit 80 reads the total amount of bills written in the second memory area 82B of the RAM 82, and displays the total amount of bills on the operator display 14 and the customer display 15.

  On the other hand, when it is determined that it is not only the banknote that is placed on the upper surface of the cash tray 17 at the time of the current imaging, the cash tray 17 is set by the customer between the previous imaging time and the current imaging time. Since the coin is considered to be further placed on the banknote placed on the upper surface of the coin, the control unit 80 determines the coin type and number of coins and the coin based on the still image data generated by the current imaging. Is calculated and written to the second memory area 82B of the RAM 82 (step SB15). At the same time, the control unit 80 reads the total amount of banknotes written in the second memory area 82B of the RAM 82, adds them up, and adds the total amount of banknotes and coins to the operator display 14 and the customer display 15. indicate.

  On the other hand, when it is determined that it is not only the bill that is placed on the upper surface of the cash tray 17 at the time of the previous imaging, only the coin is placed on the upper surface of the cash tray 17. Therefore, the bills and coins are placed on the top surface of the cash tray 17, and the bills and coins are placed on the top surface of the cash tray 17 even during the current imaging. When banknotes and coins are placed on the upper surface of the cash tray 17, usually coins are placed on the banknotes.

  Therefore, the control unit 80 compares the pattern of the still image data captured last time with the pattern of the still image data captured this time, and the cache tray 17 between the previous imaging time and the current imaging time. It is determined whether the bill is a bill or a coin (step SB16). When it is determined that the bill is a bill, the bill of the bill is determined based on the still image data generated by the current imaging. The denomination and number of sheets and the total amount of bills are newly calculated and written in the second memory area 82B of the RAM 82 (step SB17). At the same time, the control unit 80 reads the total amount of coins written in the second memory area 82B of the RAM 82, adds them up, and puts the total amount of bills and coins on the display 14 for the operator and the display 15 for the customer. indicate.

  On the other hand, if it is determined that it is a coin that has been added to or placed on the top surface of the cash tray 17 between the previous imaging and the current imaging, Based on the still image data generated by the imaging, the denomination and number of coins and the total amount of coins are newly calculated and written in the second memory area 82B of the RAM 82 (step SB18). At the same time, the control unit 80 reads the total amount of banknotes written in the second memory area 82B of the RAM 82, adds them up, and adds the total amount of banknotes and coins to the operator display 14 and the customer display 15. indicate.

  The above processing is repeatedly executed at predetermined time intervals, and when the operator determines that the customer has paid for the trading price, the operator inputs a received amount confirmation signal instructing that the received amount should be confirmed on the touch panel 13. (Step SB19).

  The received amount confirmation signal is output to the control unit 80. When the control unit 80 receives the received amount confirmation signal, the total amount of bills and / or coins stored in the second memory area 82B is determined as the received amount, The received amount is displayed on the operator display 14 and the customer display 15 (step S7).

  The control unit 80 further calculates the amount of change by comparing the data relating to the received amount thus determined with the data relating to the buying and selling amount of the product purchased by the customer stored in the first memory area 82A of the RAM 82. The amount of change is displayed on the display 14 for operator and the display 15 for customer, and the denomination and number of banknotes and / or the denomination and number of coins to be paid to the customer as change are determined, together with the amount of change, Write to the third memory area 82C of the RAM 82 (step S8).

  In step SB19, when the operator determines that the received amount displayed on the operator display 14 is incorrect for some reason, the operator inputs a received amount correction signal to the touch panel 13 and inputs the correct received amount to the touch panel. 13 is input.

  The received money amount correction signal input to the touch panel 13 and the data related to the correct received money amount are input to the control unit 80. When the received money amount correction signal is received, the control unit 80 is written in the second memory area 82B of the RAM 82. Rewrite the amount received from customers. Next, when the receipt amount confirmation signal is input to the touch panel 13 by the operator, the control unit 80 stores the data regarding the corrected receipt amount in the first memory area 82A of the RAM 82 for the purchase amount of the product purchased by the customer. The amount of change is calculated in comparison with the data relating to the amount of money, and the total sales amount stored in the first memory area 82A of the RAM 82, the received amount and the amount of change stored in the second memory area 82B of the RAM 82 Is displayed on the display 14 for the operator and the display 15 for the customer. At the same time, the control unit 80 determines the number of banknotes to be paid to the customer as change and / or the denomination and number of coins and stores them together with the change amount in the third memory area 82C of the RAM 82 (step S8).

  Next, the control unit 80 outputs a withdrawal instruction signal to the second controller 100 of the coin depositing / dispensing mechanism 22 of the coin depositing / dispensing machine 20 based on the determined number of coins to be dispensed. Based on the determined number of banknotes to be withdrawn, a withdrawal instruction signal is output to the third controller 110 of the banknote dispensing mechanism 23 of the money depositing and dispensing machine 20.

  When the control unit 80 outputs the second controller 100 of the coin depositing / dispensing mechanism 22 of the money depositing / dispensing machine 20 and the third controller 110 of the bill dispensing mechanism 23 of the money depositing / dispensing machine 20, The change is paid out from the money depositing / dispensing machine 20 in the same manner as the embodiment shown in FIGS.

  According to this embodiment, the amount of cash received on the upper surface of the cash tray 17 by the customer as the purchase price of the product is captured by the camera 18 at the predetermined time interval. Still image data of banknotes and / or coins placed on the top surface of the cash tray 17, optical reference data on the size, color, and surface pattern of banknotes and / or diameters of coins, and presence / absence of holes The POS terminal device 1 is configured to determine the banknote and / or coin denomination and number of coins placed on the upper surface of the cash tray 17 in comparison with the optical reference data about the color. Since the amount received from the customer is tentatively determined, the operator is completely responsible for determining the amount received from the customer Therefore, it is possible to reduce the mental burden on the operator, and since the change is paid immediately after the amount received is confirmed, it takes a long time to pay the change and wastes time for the customer. This can be reliably prevented.

  Further, when the operator reaches for the upper surface of the cash tray 17, the control unit 80 automatically receives the bills and / or coins received on the cash tray 17 by the customer. The operator may determine that the banknotes and / or coins placed on the upper surface of the cash tray 17 by the customer are reaching out to confirm for the hand. Even after reaching for the upper surface of the cash tray 17, it is useless to calculate the denomination and number of banknotes and / or coins placed on the upper surface of the cash tray 17 based on the captured still image data. This is a process and causes an error in calculating the amount received. However, according to the present embodiment, when the operator reaches for the top surface of the cash tray 17, the still image data captured after the operator reaches for the cash tray 17 is invalidated, and the previous time The banknotes on the cash tray 17 calculated at the time of imaging, that is, based on the still image data generated at the time of imaging before the operator reaches for the cash tray 17 and written in the second memory area of the RAM 82 And / or coin denomination and number and the total amount are kept as they are, which is very efficient, and as a result of the operator confirming the banknote and / or coin, The amount of coins received is the amount of bills and / or coins captured by the camera 18 If the received amount from the customer calculated based on the image data matches, the operator immediately inputs a received amount confirmation signal to the touch panel 13. If not, the operator receives the received amount from the customer. The received money amount correction signal is input to the touch panel 13 and the correct received money amount is input to the touch panel 13 and then the received money amount confirmation signal is input to the touch panel 13. It becomes possible to effectively prevent the calculation error of the denomination and the number of bills and / or coins due to being extended toward the upper surface of the cash tray 17.
