  FIG. 5 shows an example of a registration screen displayed on the operator display 21 by the display control function (1). The registration screen 300 includes a title area 301 arranged at the upper part of the screen, a current area 302 arranged at the left side of the lower part of the screen, a total amount display area 303 arranged at the right side of the lower part of the screen, and the right end of the middle part of the screen. Placed in the middle of the screen, the single item registration area 305 located in the middle of the screen and adjacent to the category area 304, and the middle portion of the screen located in the position adjacent to the left end of the single item registration area 305 It consists of a receipt image display area 306.

  In the category area 304, a category key 304a for displaying a category of a product such as “sale item”, “vegetables”, “fruit”, “prepared food” is displayed. In the single item registration area 305, preset keys 305a with product images such as “tomato”, “cucumber”, “carrot”, “potato”, and “bitter”, according to the category designated by the category key 304a, A preset key 305b with no product image such as “ginger”, “nira”, “elinge”, and a preset key 305c such as “green onion with organic mud”, “cutting onion wash” are displayed. Each preset key displayed in the single item registration area 305 is set to an integral multiple of the minimum area ma. In the example shown in FIG. 5, each preset key 305a is displayed 16 times (4 rows × 4 columns) of the minimum area ma, and each preset key 305b is displayed 4 times (2 rows × 2 columns) of the minimum area ma. Each preset key 305c is displayed by 8 times (2 rows × 4 columns) of the minimum area ma.

  In the receipt image display area 306, for each product information registered in the product information registration area 110, the name, the number of purchases, and the price of each product are displayed. The receipt image display area 306 is set to an integral multiple of the minimum area ma, as with each preset key. In the example shown in FIG. 5, it is displayed in 64 times (16 rows × 4 columns) of the minimum area ma.

  Note that the combined display area of the single item registration area 305 and the receipt image display area 306 is fixed to 320 times (16 rows × 20 columns) of the minimum area ma (default area). In the operation to be described later, the combined display area of the single item registration area 305 and the receipt image display area 306 satisfies the predetermined area and does not exceed the predetermined area. The display area is adjusted.

[Operation]
Next, operations of the main body 4 and the product information input unit 6 according to the present invention will be described.
The operator can operate the keyboard 10 or touch panel 12 of the main body 4 to display a maintenance menu on the operator display 11 and change the size of the receipt image display area 306 of the registration screen 300 by an integral multiple of the minimum area ma. it can. Processing executed by the CPU 100 of the main body 4 and the CPU 200 of the product information input unit 6 in this change will be described with reference to the flowchart of FIG.

  First, the CPU 100 of the main body 4 waits for designation of the width of the receipt image display area 306 (steps S101 and S102). At this time, the operator can specify the width of the receipt image display area 306 by operating the keyboard 10 or the touch panel 12 of the main body 4. For this specification, for example, data for predetermining a plurality of widths such as large (width 12W), medium (width 8W), and small (width 4W) is stored in the ROM 101 or the HDD 104, and an operator designates the data. The operator may input the width of the receipt image display area 306 via the keyboard 10 or the touch panel 12 so as to be an integral multiple of the minimum area ma.

  If the width of the receipt image display area 306 is designated by the method as described above (Yes in step S102), the CPU 100 displays the upper right corner and the lower right row of the receipt image display area 306 registered in the display position designation data 113. The display position is adjusted according to the width for which the designation is accepted (step S103).

  Further, when the CPU 100 displays the single item registration area 305 and the receipt image display area 306 registered in the area data 112 on the display 21 for operator according to the display position designation data 113, the receipt image display area 306 and the single item registration area 305 are displayed. Are identified, and the flag F registered at a location corresponding to the corresponding area in the flag data 115 is set to "1" (step S104). Note that the flag F registered in a portion corresponding to an area other than the overlapping area is set to “0”. After updating the flag F in this way, the CPU 100 transmits the screen data 111 to the product information input unit 6 via the connection I / Fs 105 and 203. When the screen data 111 is received from the main body 4, the CPU 200 of the product information input unit 6 stores the received screen data 111 in the RAM 202, and the operator uses the area data 112 and the display position designation data 113 constituting the screen data 111. The registration screen displayed on the display 21 is updated (step S105). Thus, a series of change processing is completed.

  FIG. 7 and FIG. 8 show examples of registration screens displayed on the operator display 21 of the product information input unit 6 as a result of changing the size of the receipt image display area 306. FIG. 7 shows an example in which the width of the receipt image display area 306 of the registration screen 300 shown in FIG. 5 is expanded to eight times the width W of the minimum area ma. FIG. 8 shows the registration screen 300 shown in FIG. This is an example in which the receipt image display area 306 is expanded to 12 times the width W of the minimum area ma.

  In the registration screen 300 shown in FIG. 7, the receipt image display area 306 covers the portions corresponding to four columns from the left end of the single item registration area 305 to the minimum area ma by expanding the width of the receipt image display area 306. Has been. As a result, the flag F corresponding to the four columns in the flag data 115 is set to “1”. Further, because the width of the receipt image display area 306 is widened, the purchased product information that has been displayed in two stages on the registration screen 300 shown in FIG. 5 is displayed in one stage except for the lowest stage.

  In the registration screen 300 shown in FIG. 8, the receipt image display area 306 covers and covers the portions corresponding to eight columns of the minimum area ma from the left end of the single item registration area 305 by widening the receipt image display area 306. Has been. As a result, the flag F corresponding to the eight columns in the flag data 115 is set to “1”. Further, because the width of the receipt image display area 306 is widened, all of the purchased merchandise information displayed in two stages on the registration screen 300 shown in FIG. 5 is displayed in one stage.

  Thus, by changing the width of the receipt image display area 306 so as to cover the single item registration area 305, the combined display area of the single item registration area 305 and the receipt image display area 306 satisfies the predetermined area, and , It will be changed within the range not exceeding this default area.

  If the purchased product information displayed in the second row is displayed in one row as in the receipt image display area 306 of the registration screen 300 shown in FIGS. 7 and 8, more purchased product information is collectively displayed. Since it can display in the said area 306, an operator becomes easy to notice misoperation.

Next, processing executed by the CPU 100 of the main body 4 and the CPU 200 of the product information input unit 6 when inputting product information using the registration screen 300 will be described with reference to the flowchart of FIG.
During execution of the product registration work, the CPU 200 of the product information input unit 6 displays the registration screen 300 on the operator display 21 and waits for a touch operation on the touch panel 22 (steps S201 and S202). At this time, if the operator touches the touch panel 22 (Yes in step S202), the CPU 200 specifies the position (row m, column n) of the minimum area ma that has been touched, and specifies the specified position (row m, column). The value of the flag F for n) is specified from the flag data 115 stored in the RAM 202 (step S203). Thereafter, the CPU 200 determines whether the value of the specified flag F is “1” or “0” (step S204).

  When the value of the specified flag F is “0” (“F = 0” in step S204), the touch operation can be performed in the touch area such as the category key 304a, the preset keys 305a, 305b, and 305c. The key is displayed. Therefore, the CPU 200 specifies information associated with the area from the position specifying data 114 and executes an operation based on the specified information. That is, when one of the category keys 304a is operated, the preset keys 305a, 305b, and 305c displayed in the single item registration area 305 are changed according to the category indicated by the operated category key 304a, and the preset key 305a is changed. , 305b, 305c, the product information associated with the preset key operated via the connection I / F 203, 105 is input to the main body 4 as purchased product information (step S205). ). After executing the process according to the operation key as described above, the CPU 200 waits for the next touch operation on the touch panel 22 (step S201).

  On the other hand, when the value of the specified flag F is “1” (“F = 1” in step S204), the touched area is an area other than the category area 304 or the single item registration area 305, or a single item. Although it is a display area of the registration area 305, it is an area that is hidden by the receipt image display area 306 and is not actually displayed on the screen. In such a case, since the touch operation is an erroneous operation, the CPU 200 waits for the next touch operation on the touch panel 22 without performing the process of step S205 (step S201).

  As is well known, when a bar code attached to a product is read by the vertical scanner 24 or the hand-held scanner 25, the information read via the connection I / Fs 203 and 105 is purchased as main product information. 4 When the purchased product information is input to the main body 4 in this way, the CPU 100 of the main body 4 registers the input purchased product information in the product information registration area 110 of the RAM 102, and displays a current area 302 and a total price display area 303. , Information to be displayed in the receipt image display area 306 is transmitted to the product information input unit 6. When receiving this information, the merchandise information input unit 6 updates the display content of each part of the registration screen 300 using the information. That is, the purchased product information input immediately before is displayed in the current area 302, the total score and the total amount of the total amount display area 303 are updated, and the purchased product information input immediately before is added to the receipt image display area 306. To do.

  When the operator has finished inputting the merchandise information for all of the customer's purchased merchandise, as is well known, the keyboard 10 of the main body 4 or the keyboard 20 of the merchandise information input unit 6 is operated to complete the commercial transaction. When the commercial transaction is completed, the purchased product information registered in the product information registration area 110 is cleared, and accordingly, the purchased product information is deleted from the receipt image display area 306 of the registration screen 300.

  As described above, the POS terminal in the present embodiment displays the preset key and the receipt image on the operator display 21 and accepts designation of the display width of the receipt image, and the single item registration area 305 and The width of the receipt image display area 306 is changed complementarily. By using this function, for example, when there are many opportunities to input product information using the vertical scanner 24 or the hand-held scanner 25, the receipt image display area 306 can be enlarged and the single item registration area 305 can be displayed smaller. The receipt image display area 306 can be reduced and the single item registration area 305 can be displayed larger when there are many opportunities to input product information using the. That is, a registration screen that realizes quick input of purchased merchandise information using a preset key and prevention of erroneous input using a receipt image can be configured with a high degree of freedom and can be used for the convenience of the operator of the registration screen.

  In addition, the POS terminal displays the single item registration area 305 and the receipt image display area 306 on the registration screen 300 in a size that is an integral multiple of the minimum area ma that can be touch specified on the touch panel 22, and the size of both areas 305 and 306. Is adjusted to be an integral multiple of the minimum area ma. In this way, since the boundary between the single item registration area 305 and the receipt image display area 306 does not extend over the minimum area ma, the operation cannot be performed even though a part is displayed on the registration screen 300. There are no preset keys.

  Further, the POS terminal changes the sizes of the single item registration area 305 and the receipt image display area 306 in a complementary manner while satisfying the predetermined area. Therefore, if the size of the receipt image display area 306 is increased / decreased, the size of the single item registration area 305 is always increased / decreased by the increase / decrease. Become.

  In addition, when the receipt image display area 306 is enlarged and the single item registration area 305 is reduced, the POS terminal covers both areas 305, The size of 306 is changed. In this way, since it is not necessary to make any changes to the area data 112 itself of the single item registration area 305, the processing time of the CPUs 100 and 200 required to change the size is shortened. Furthermore, since the position, size, and range of the preset key registration screen 300 as a whole are not changed, it is convenient for a skilled operator who stores and operates the position of the preset key in the single item registration area 305.

  Further, when a part of the preset key is covered with the receipt image, the POS terminal sets the flag F of the covered area to “1” and does not accept a touch operation on the area. Therefore, even if the receipt image on the registration screen 300 is touched by mistake, the merchandise information assigned to the preset key hidden by the receipt image is not input as the purchased merchandise information.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.

  For example, in the embodiment, the case where the present invention is applied to a two-person POS terminal and the display content of the registration screen 300 displayed on the operator display 21 of the product information input unit 6 is changed has been described. However, the application target of the present invention is not limited to this. For example, a one-person POS terminal that does not include a product information input unit and is provided with an input interface for purchased product information such as a hand-held scanner on the POS terminal body. You may apply to. In this case, the registration screen 300 disclosed in the embodiment is displayed on an operator display provided in the POS terminal main body. Even in a POS terminal including the product information input unit 6, the registration screen 300 may be displayed on the operator display 11 of the main body 4.

  Further, in the above-described embodiment, the case has been described in which the designation of the width of the receipt image display area 306 is received and the size of the receipt image display area 306 is changed according to the designated width. However, the designation of the width of the single item registration area 305 may be received, the size of the single item registration area 305 may be increased or decreased according to the received width, and the size of the receipt image display area 306 may be increased or decreased by the increased or decreased area. Even in this case, since the single item registration area 305 and the receipt image display area 306 are adjusted complementarily within the predetermined area, the same as the case where the designation of the width of the receipt image display area 306 is accepted and changed. The effect of. Also, instead of accepting designation only of the width, designation of the size including the height of the single item registration area 305 or the receipt image display area 306 is accepted, and the height of the single item registration area 305 and the receipt image display area 306 is determined according to the accepted size. The height and width may be changed.

  In the embodiment, when the size of the receipt image display area 306 is enlarged, a part of the single item registration area 305 is covered. However, instead of obscuring a part of the single item registration area 305, the single item registration area 305 may be reduced to compensate for the enlarged area of the receipt image display area 306.
