In the drawer 18, the opening portion opens the drawer portion according to an instruction from the CPU 11. The opened drawer is manually closed by the operator after cash storage or the like.

  Next, the screen setting table 20 and main display screens stored in the storage unit 16 will be described with reference to FIGS. FIG. 2 is a diagram showing the configuration of the screen setting table 20. FIG. 3 is a diagram showing the input screen 30A. FIG. 4 is a diagram showing the configuration of the input screen 30B.

  The screen setting table 20 is a table for setting a default input screen for each operator. As shown in FIG. 2, the screen setting table 20 has items of an operator 21 and a setting value T22.

  The operator 21 is an identification number of an operator who uses the ECR 10. It is assumed that an operator who uses the ECR 10 can register up to four people. The numbers of the operators are set to 01, 02, 03, 04 in order. However, the maximum number of operators that can be registered in the ECR 10 may be a number other than four.

  The set value T22 is identification information of an input screen of default display corresponding to the operator 21. When the setting value T22 is “0”, the input screen 30A in which the detail area is enlarged is shown. When the set value T22 is “1”, an input screen 30B in which the detail area is reduced is shown.

  With reference to FIG. 3, the input screen 30A in which the detail area is enlarged will be described. The input screen 30 </ b> A is an input screen for an operator who is not familiar with the operation of the ECR 10. The input screen 30A includes a total area 31, a detail area 32A, a numeric display key 33, a correction key 34, an operator key 35, a PLU key 36, a cancel key 37, and a payment key 38.

  The total area 31 is a display area for displaying a subtotal, a total price, etc., of the prices of products registered for sale. The detail area 32A is a display area for displaying detailed information such as the PLU number and price of a registered single product, and is enlarged and relatively large in size.

  The numeric display key 33 is a key for accepting display switching between the input screen 30A in which the detail area is enlarged and the input screen 30B in which the detail area is reduced. That is, when the numeric display key 33 is touch-input while the input screen 30A is displayed, the input screen 30B is displayed. When the numeric display key 33 is touch-input while the input screen 30B is displayed, the input screen 30A is displayed.

  The detail area 32B is smaller than the detail area 32A and is relatively small in size. The numeric key 39B1 and the closing key 39B2 are arranged in an area that does not overlap the detail area 32B among the areas corresponding to the detail area 32A. That is, the detail area 32A is reduced to the detail area 32B, and the numeric key 39B1 and the closing key 39B2 are arranged in the empty space. The numeric key 39B1 is a so-called numeric keypad and includes keys of 0 to 9000 and clear (C). The closing key 39B2 includes a subtotal key, a loan (sell) key, a ticket (sell) key, and a cash (/ close) key.

  Next, the operation of the ECR 10 will be described with reference to FIGS. FIG. 5 is a flowchart showing money registration processing. FIG. 6 is a diagram showing an amount input screen 30C. FIG. 7 is a diagram showing a payment input screen 30D.

  The money registration process is a process of registering merchandise information (sales data) at the time of customer accounting in response to an operation input by the operator. In the ECR 10, for example, when the power is turned on or a monetary registration process execution instruction is input from the store manager via the operation unit 12, the CPU 11 reads the monetary registration program 151 read from the ROM 15. In cooperation with, cash registration processing is executed.

  An operator who uses the ECR 10 stands in front of the ECR 10 and inputs an operation for money registration, and changes with another operator as appropriate depending on work status, rotation, and the like. Further, it is assumed that the initial value of the variable T on the input screen is set to 1 (detail area expansion). However, for example, when there are many operators who are familiar with the operation, the initial value of the variable T may be set to zero.

  As shown in FIG. 5, first, according to the initial value of the variable T, the CPU 11 displays an input screen 30A in which the detail area is enlarged on the display unit 14 as an input screen at the start of the money registration process (step S14). S10).

  And CPU11 receives the touch input of the key from an operator via the operation part 12 corresponding to the display screen of the display part 14 (step S11). Then, the CPU 11 determines whether or not the key input in step S11 is the operator key 35 (step S12).

  When the input key is the operator key 35 (step S12; YES), the CPU 11 refers to the screen setting table 20 stored in the storage unit 16 and corresponds to the operator 21 of the operator key 35 input in step S11. The set value T22 to be substituted is substituted for the variable T (step S13). Then, the CPU 11 determines whether or not the variable T = 1 (detail area expansion) (step S14).

  When the variable T = 1 (step S14; YES), the CPU 11 displays the input screen 30A in which the detail area is enlarged on the display unit 14 (step S15), and proceeds to step S11. When the variable T = 0 (detail area reduction) (step S14; YES), the CPU 11 displays the input screen 30B with the detail area reduced on the display unit 14 (step S16), and proceeds to step S11.

  When the input key is not the operator key 35 (step S12; NO), the CPU 11 determines whether or not the key input in step S11 is the numeric display key 33 (step S17). When the input key is the numeric display key 33 (step S17; YES), the CPU 11 determines whether or not the variable T = 1 (step S18).

  When the variable T = 0 (step S18; NO), the CPU 11 displays the input screen 30A in which the detail area 32B of the input screen 30B being displayed is enlarged on the display unit 14, and substitutes 1 for the variable T (step). S19), the process proceeds to step S11. When the variable T = 1 (step S18; YES), the CPU 11 displays the input screen 30B in which the detail area 32A of the input screen 30A being displayed is reduced on the display unit 14, and substitutes 0 for the variable T (step S20), the process proceeds to step S11.

  If the input key is not the numeric display key 33 (step S17; NO), the CPU 11 determines whether or not the key input in step S11 is the PLU key 36 (step S21). When the input key is the PLU key 36 (step S21; YES), the CPU 11 determines whether or not the variable T = 1 (step S22).

  When the variable T = 0 (step S22; NO), the CPU 11 registers (registers as a product) the entered number as a product price (unit price) together with the PLU number of the input PLU key 36 (step S23). ), The process proceeds to step S11. In step S23, the PLU number and the amount registered for the product are displayed in the detail area 32B. In step S23, if there is no input number and the amount corresponding to the PLU number of the input PLU key 36 is set in the PLU setting table stored in the storage unit 16, the setting is performed. Is registered.

  When the variable T = 1 (step S22; YES), the CPU 11 displays the amount input screen 30C on the display unit 14, and the amount of money via the operation unit 12 corresponding to the amount input area 39C of the amount input screen 30C. The input is accepted, the input amount is registered (product registration) together with the PLU number of the input PLU key 36, the input screen 30A is displayed on the display unit 14 (step S24), and the process proceeds to step S11. In step S24, the PLU number and the amount registered for the product are displayed in the detail area 32A. In step S24, if there is no input number and the amount corresponding to the PLU number of the input PLU key 36 is set in the PLU setting table stored in the storage unit 16, the amount input is performed. The set amount is registered without displaying the screen 30C.

  Here, with reference to FIG. 6, the money amount input screen 30C displayed in step S24 will be described. The amount input area 39C is an amount input dialog, and includes an amount display area 39C1, a numeric key 39C2, and an OK key 39C3. The monetary amount display area 39C1 is a display area for the monetary amount entered with the numeric key 39C2. A numeric key 39C2 is a numeric keypad for inputting a numeric value. The OK key 39C3 is a key for confirming the numeric value input by the numeric key 39C2 as an amount.

  When the input key is not the PLU key 36 (step S21; NO), the CPU 11 determines whether or not the key input in step S11 is the payment key 38 (step S25). When the input key is the payment key 38 (step S25; YES), the CPU 11 displays the payment input screen 30D on the display unit 14 (step S26), and proceeds to step S11.

  Here, the payment input screen 30D displayed in step S26 will be described with reference to FIG. The payment input screen 30D has a total area 31, a detail area 32A, an operator key 35, a cancel key 37, a numeric key 39D1, and a closing key 39D2. The numeric key 39D1 is a numeric keypad similar to the numeric key 39B1. The fastening key 39D2 is a key group similar to the fastening key 39B2. The numeric key 39D1, the numeric key 39D1, and the closing key 39D2 are arranged at the position of the PLU key 36 on another input screen.

  Since the input screen 30A does not include a closing key, the payment input screen 30D must be displayed in order to perform the closing process. On the other hand, since the closing key 39B2 is included in the input screen 30B, the display of the payment input screen 30D is not essential even when performing the closing process.

  When the input key is not the payment key 38 (step S25; NO), the CPU 11 performs a process corresponding to the other key input in step S11 (step S27). And CPU11 discriminate | determines whether the process in step S27 is the fastening process according to the input of the cash (/ tightening) key of the closing key 39B2 or 39D2 (step S28).

  When it is not a tightening process (step S28; NO), it transfers to step S11. When it is a fastening process (step S28; YES), CPU11 displays the input screen 30A or 30B according to the variable T on the display part 14 (step S29), and transfers to step S11.

  As described above, according to the present embodiment, the ECR 10 receives a touch input on the display screen of the display unit 14 by the operation unit 12, and includes the detail area 32A, the PLU key 36, and the numeric display key 33, An input screen 30B that includes an input screen 30A that does not include a numeric key, a detail area 32B that is smaller than the detail area 32A, a PLU key 36, a numeric key 39B1, and a numeric display key 33. Either one is displayed on the display unit 14. The ECR 10 switches the input screens 30 </ b> A and 30 </ b> B to be displayed on the display unit 14 when the numeric display key is touch-input by the operation unit 12.

  For this reason, the operability on the input screen can be improved for all operators with different levels of operation proficiency. More specifically, an operator who is proficient in operation can use the input screen 30B that can be operated in detail using the numeric keys, and can improve the operability for the proficient operator and is proficient in operation. An operator who is not yet able to use the input screen 30A that can easily operate because there is no numeric key, can improve the operability even for an operator who is not familiar.

  Further, the ECR 10 receives an input of an operator who uses the ECR 10 from the operation unit 12, stores the screen setting table 20 in the storage unit 16, and when the operator inputs, the ECR 10 is input using the screen setting table 20. The input screen 30A or 30B corresponding to the operator is displayed on the display unit 14. For this reason, the input screen 30A or 30B corresponding to the operator can be appropriately displayed as a default.

  In addition, when the PLU key 36 is touch-input while the input screen 30A is being displayed, the ECR 10 displays an amount input area 39C for inputting a numerical value corresponding to the PLU key 36 on the input screen 30A. The money amount input screen 30C is displayed, and the number entered corresponding to the money amount input area 39C is accepted as the money amount. For this reason, an operator who is not familiar with the operation can easily input the amount of the PLU.

  The input screen 30A includes a payment key 38 for displaying a payment input screen 30D that includes a detail area 32A, a numeric key 39D1, and a closing key 39D2, and does not include the PLU key 36. The ECR 10 displays a payment input screen 30 </ b> D on the display unit 14 when the payment key 38 is touch-input by the operation unit 12. For this reason, even when the input screen 30A is used, by executing the payment input screen 30D, it is possible to reliably complete the tightening process by the tightening key 39D2.

  In the above description, the example in which the ROM 15 is used as the computer-readable medium of the program according to the present invention is disclosed, but the present invention is not limited to this example. As other computer-readable media, a non-volatile memory such as a flash memory and a portable recording medium such as a CD-ROM can be applied.
