Description

The present invention relates to a control device, printer, and a program.

  A label printer that accepts input from an operator by a key operation unit and prints print information including a unit price of a product based on a predetermined format is disclosed in Patent Document 1.

JP-A-10-324320

  By the way, when a numerical value such as a unit price is input to the label printer, the operator performs an input operation for once entering a numerical value, and then performs an operation for designating an input destination for inputting the numerical value. And since each input item has a limit on the number of digits that can be input, if the input value does not meet the allowable range of the specified input item, it will be determined that the number of digits overflows when the input item is specified, for example. The display is output. Here, when there are multiple input items, the allowable number of digits differs depending on the input item, so it is not possible to remember the number of digits allowed to be input in all input items. There was a fear. If an incorrect number of digits are entered, it is determined that there is an error in the number of digits when the input destination is specified, and the correct number of digits is entered again after confirming the number of digits allowed for the input. There was a case where correct numerical values could not be input quickly due to work.

  The present invention has been made in view of the above points, and it is an object of the present invention to provide a control device and a printer that can reduce the possibility that a numerical value that causes an input error will be input and can quickly input a numerical value. To do.

According to one aspect of the present invention, there is provided display means for displaying a pricing screen including an input frame for displaying a numerical value input by an operator and an item frame as an output destination of the numerical value input to the input frame; and a predetermined operation depending on the control means for displaying the numerical tolerance information on the display means with respect to the items frame, Bei example, said predetermined operation is Ru operation der least one order of numerical to the input frame is input This is a control device characterized by that.
As a result, the control device can reduce the possibility of input of a numerical value causing an input error by showing the operator numerical value allowable range information of an item for outputting the input numerical value in the operator's input operation. Quick numerical input is possible. In this case, when there are multiple item frames that are the output destinations of the input numerical values, the numerical value allowable range information to be displayed is to display the numerical value allowable range information for all the item frames at a time. Alternatively, when the item frame that is the output destination of the input numerical value is limited, the numerical value allowable range information for the limited item frame may be displayed.
Moreover, since the numerical value tolerance range information is displayed only by inputting at least one digit in order to input a numerical value, the range can be confirmed immediately.

In the control device, the control means may display the numerical value tolerance range information in the vicinity of the item frame.
As a result, it is possible to check the numerical value tolerance of the item frame in the vicinity of the item frame where the numerical value is to be input, reducing the burden of checking the numerical value allowable range, and the operator can quickly enter the numerical value. It can be performed.

In the control device, the control means determines whether or not the input numerical value satisfies the numerical value allowable range information in the item frame every time a numerical value is input to the input frame. As a result of the determination, a prohibition display may be displayed in the item frame where the numerical value input in the input frame is not allowed.
As a result, it is possible to prevent the numerical value input in the input frame from being erroneously input to the item frame that has been prohibited. In addition, every time a digit is entered in the input frame, a prohibition display is made for the item frame that is out of the allowable range. It can be recognized that a numerical value outside the allowable range in the item frame has been input to the input frame. Therefore, the operator can recognize an error in numerical input at an early stage, correct the numerical value within the allowable range, and input it quickly.

Another aspect of the present invention is a printer comprising the above-described control device and a printing unit that prints a print content including data input to the item frame on a medium in a predetermined format.
Thus, the printer can reduce the possibility that a numerical value that causes an input error is input by indicating to the operator the numerical value allowable range of the item for outputting the input numerical value in the input operation of the operator.
According to another aspect of the present invention, there is provided a computer of a control apparatus for displaying a pricing screen including an input frame for displaying a numerical value input from an operator and an item frame as an output destination of the numerical value input to the input frame. And a program for realizing a control function for displaying the numerical value tolerance range information for the item frame on the pricing screen according to a predetermined operation, wherein the predetermined operation is applied to at least one of the input frames. The program is an operation for inputting a numerical value of a digit.

  According to the present invention, the control means displays the input numerical value allowable information on the display means when the operator performs an input operation to enter a numerical value such as a unit price, so that a numerical value that is not determined as an input error can be displayed to the operator. It can be confirmed. Therefore, it is possible to reduce the possibility that a numerical value that causes an input error is input, and it becomes possible to input a numerical value quickly.

It is a figure which shows the example of the item setting file in the embodiment. It is an example of the pricing screen in the same embodiment. It is a display example on the pricing screen in the same embodiment. It is a display example on the pricing screen in the same embodiment. 6 is a flowchart illustrating an example of an operation procedure of the label printer in the embodiment.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of a label printer. The label printer 1 includes a control device 100, a scale 2, a printing mechanism unit 3 (printing unit), and an operation unit 5. The scale 2 has a load cell 2a. The load cell 2a measures the weight of the product and outputs a signal indicating the weight of the product to the control device 100. The print mechanism unit 3 prints print data (print contents) on a label (medium) in a print format under the control of the control device 100 and issues the printed label.

  The operation unit 5 includes a key operation unit 7, a touch panel 9a, and a liquid crystal display 9b (display means). The key operation unit 7 receives an operation input by the operator and outputs a signal corresponding to the operation input via the key operation unit 7 to the control device 100. The key operation unit 7 includes a numeric key and a product number key (a key for declaring calling a product number in a product file). The touch panel 9a receives an operation input (for example, an operation of pressing an icon image) by an operator, and outputs a signal corresponding to the operation input via the touch panel 9a to the control device 100. The liquid crystal display 9b is provided integrally with the touch panel 9a, and displays an image based on control by the control device 100. The resolution of the liquid crystal display 9b is, for example, 640 × 480 [dots]. The liquid crystal display 9b is only a specific example of a display provided in the operation unit 5. Instead of the liquid crystal display 9b, for example, organic EL (Electro Luminescence) may be provided as a display.

  The control device 100 controls each part of the label printer 1. The control device 100 includes a CPU 20 (Central Processing Unit) (control means), a load cell control unit 21, a print control unit 22, an operation control unit 24, a display control unit 25, a RAM 30 (Random Access Memory), and a ROM 40. (Read Only Memory).

  The ROM 40 stores a control program in advance. The ROM 40 expands the control program in the RAM 30 when the control device 100 is powered on and supplied with power. A signal indicating the weight of the product is input to the load cell control unit 21 from the load cell 2 a of the scale 2. The load cell control unit 21 transfers a signal indicating the weight of the product to the CPU 20. The print control unit 22 executes image processing (for example, bitmap processing) based on control by the CPU 20 and controls the print mechanism unit 3. For example, the print control unit 22 controls the print mechanism unit 3 to print the print data on the label in a predetermined print format. Note that a signal indicating a printing result may be input from the printing mechanism unit 3 to the printing control unit 22.

  The display control unit 25 executes image processing based on control by the CPU 20. Further, the display control unit 25 controls the liquid crystal display 9b to display various screens subjected to image processing (which will be described later with reference to FIGS. 4 to 6). A signal corresponding to an operation input via the key operation unit 7 is input to the operation control unit 24 from the key operation unit 7 of the operation unit 5. For example, when a signal indicating a price is input from the key operation unit 7, the operation control unit 24 transfers a signal indicating the price to the CPU 20. A signal corresponding to an operation input via the touch panel 9 a is input to the operation control unit 24 from the touch panel 9 a of the operation unit 5. For example, when a preview instruction signal instructing execution of a preview is input from the touch panel 9a, the operation control unit 24 transfers the preview instruction signal to the CPU 20.

  The RAM 30 temporarily stores various data. For example, the RAM 30 temporarily stores a control program developed from the ROM 40. For example, the RAM 30 temporarily stores a product file and a format file. As will be described later, the product file stores, for example, a subcode, a product name, and a price for each product number. The product number indicates the product identification number. The product name indicates the product name of the product. The price indicates the price of the product. A format file (print format file) (not shown), for example, for each format number, is a print position (a point (start point) X for forming (setting) a rectangular area for printing print data) for each print item. Coordinate, Y coordinate), width data from the start point (widths in the X and Y directions from the start point for forming the rectangular area), print orientation (vertical / horizontal), typeface, and the like. The print format file stores the print position, width data, print orientation, typeface, and the like in association with the format number and print items. That is, the print format file includes a plurality of print items included in each print format (each print format is identified by a format number), a print area of each print data of each of the plurality of print items (each print item of each print item). A rectangular area for printing the print data), the print direction of each print data, the typeface of each print data, and the like are set. Since the format number in the print format file is stored in the product file corresponding to the product number in the product file (not shown), the product in the product file is read out. The label is issued in a predetermined print format.

  The CPU 20 is connected to each unit of the control device 100 via a bus. The CPU 20 controls each unit of the control device 100 based on the control program developed in the RAM 30. In addition, the CPU 20 stores various data in the RAM 30.

FIG. 2 is a diagram illustrating an example of a product file. In the figure, the product file is a data table (product data) including items such as “product number”, “subcode”, “product name”, “price”, “additive”, “origin”, and “tray”. Is a file. Product data exists for each product sold in the store. The item “product number” is information for identifying a product. The item “subcode” is identification information used when a price is registered for each sales unit in the same product. For example, if the same product is registered as 100 yen for 1 piece and 200 yen for 2 pieces, the price “100” yen is registered by combining the product number “000001” with the subcode “1”, and the product number “000001”. "200" yen is registered by combining subcode "2" with "." The item “product name” is a name of a product, and a unique name or a general name that can be recognized by a customer is used. The item “price” represents the selling price of the product. The item “additive” is identification information of the additive. The item “production area” is identification information of the production area. The item “tray” is tray identification information. Although not shown, the RAM 30 stores an additive file, a production area file, and a tray file, and includes each piece of information uniquely associated with identification information. For example, if the “production area” is “Hokkaido production”, the production area identification information “10” is uniquely associated. Further, although not shown, since the format number in the print format file is stored in association with each product number as described above, a label suitable for the product can be issued.
In addition, in the case of a packaging device that wraps a packaged object having a label printer in the present embodiment with a film, the “tray” data is used to identify the tray identification information (the identification It is used when controlling the strength of the tension in the packaging by setting the size information of the tray together with the information. In other words, in the case of a simple label printer that does not use the packaging device, there is no need for information on the “tray”.

  FIG. 3 is a diagram illustrating an example of the item setting file. In the figure, the item setting file is a file of a data table (item setting data) including items such as “item number”, “item name”, and “number of digits that can be input”. Item setting data exists for each item included in the label to be printed. The item “item number” is information for identifying an item printed on a label. The item “item name” is the name of the item printed on the label. The item “number of digits that can be entered” indicates the number of digits that can be entered in each item. For example, in the example of FIG. 3, the item name “product number” and the number of digits that can be entered “6” are registered for the item number “1”.

  FIG. 4 is an example of a pricing screen. The pricing screen is an operation screen for an operator to call a product set in the file from a product file and issue a label for the product. Therefore, as described above, the information such as the price of each product set in the product file of FIG. 2 is specified by pressing the numeric key and the product number key of the key operation unit 7, and the product file is specified. Information on the product in the middle is called. For example, when reading the product with the product number 000001 in the product file, the information set to the product number 000001 is displayed by pressing the product number key after pressing 1 with the numeric key. The merchandise number may be input from the highest-order digit in which a number other than 0 is set, and 0s in more digits can be omitted when inputting. For example, if the product number 000100 is set, the product number key may be pressed after the input of the numeric keys 1, 0, 0.

  In addition, the set information may be temporarily changed on the pricing screen. For example, it is conceivable to change the additive data set for the product to another additive data. In the product file shown in FIG. 2, “20” is set in the product number 000002 as additive data. “20” is an identifier that defines each record in the additive file storing additive data (not shown). Since “20” is set, “20” in the additive file is set. Is controlled to be called. However, if the additive of the commodity currently received is different from the usual and the additive with the identifier “10” in the additive file is used, the key operation unit 7 continues to 1, 0. After that, by touching the item frame 210-5 (see FIGS. 4 and 5), the additive data with the identifier “10” in the additive file is set to the product with the product number 000002. It becomes like this.

  The pricing screen shown in FIG. 4 includes (arranged) an input frame (input field) 201 and item frames (item fields) 210 (item frames 210-1, 210-2,..., 210-12). ) The input frame 201 is a field for displaying the product name set in the product file. When a numeric key is pressed from the key operation unit 7, the display of the product name is erased, and the numerical value input by the operator Is controlled to be displayed. The item frame 210 receives an input for designating an output destination of the numerical value input to the input frame 201.

  FIG. 5 is a display example on the pricing screen shown in FIG. In the example shown in FIG. 5, a numerical value allowable range display 310 (310-1, 310-2,..., 310-12) is displayed for each item frame 210. The numerical value allowable range display 310 is a numerical value allowable range predetermined for each item. For example, on the setting screen (not shown) of the label printer 1, the operator inputs the number of digits (allowable digits) allowed as a numerical value input to each item via the operation unit 5. The allowable number of digits is stored (set) as numerical value allowable range information, and a range indicated by the stored numerical allowable range information is displayed as a numerical allowable range display 310. For example, as shown in FIG. 5, when the allowable number of digits for a certain item is a numerical value (when numerical allowable range information indicating that the allowable number of digits for the item is “1 digit” is stored). Is displayed as “0-9” and the allowable number of digits for an item is a numerical value of 1 to 6 digits (the allowable number of digits for the item is “1 to 6 digits”). Is stored), the numerical value allowable range display 310 displays “0-999999”.

  Specifically, when a numeric key provided in the key operation unit 7 is pressed, a number input in the input frame 201 is displayed, and when even one digit is input in the input frame 201, the item setting shown in FIG. A numerical value allowable range display 310 is displayed for an item set in the file. In the example shown in FIG. 5, since “0-999999” is displayed as the numerical value allowable range display 310-5 in the vicinity of the item frame 210-5 of the additive, the identifier value “20” described above is It can be easily confirmed that it is allowed as an input value to the item frame 210-5. Further, for example, in the example shown in FIG. 5, “0-9” is displayed as the numerical allowable range display 310-1 (310-4) in the vicinity of the subcode item frame 210-1 (210-4). It is possible to grasp in advance that an error occurs when a numerical value of two or more digits (for example, a six-digit numerical value as in other items) is input as a subcode. The same applies to other items.

  In addition, the numerical value input to the input frame 201 by touching the item frame 210 can be reflected (input) to the touched item frame 210. Therefore, for example, if the operator touches the item frame 210-5 of the additive after inputting the value “20” in the input frame 201, the operator can input the value “20” in the item frame 210-5. The same applies to other items. The subcode can be input to both the item frame 210-1 and the item frame 210-4 by touching either the item frame 210-1 or the item frame 210-4.

  Then, the numerical value displayed in the input frame 201 is touched to be input to the displayed item frame 210, and when it is input to the item frame 210, the displayed numerical value allowable range display 310 is deleted. . In addition, when an erase key (not shown) provided in the key operation unit 7 is pressed, or a product number key for specifying a product stored in the product file is pressed after the numeric key. For example, the displayed numerical value allowable range display 310 is deleted. That is, in the case where the numerical value tolerance range display 310 is displayed, for example, when a numerical value input in the input frame 201 is input (reflected) in a predetermined item frame 210, or input to the item frame 210 is unnecessary. Therefore, when the erase key is pressed, or when there is an operation other than the input to the item frame 210 (for example, the product number key is displayed after the numeric key to call the product in the product file) When the button is pressed), it is not necessary to continue displaying the numerical value tolerance range display 310, so the displayed numerical value tolerance range display 310 is temporarily deleted. Further, when even one digit of the numeric key of the key operation unit 7 is newly input, the numerical value allowable range display 310 is displayed again. That is, the numerical value allowable range display 310 is confirmed when a numerical value is input to the item frame 210, and is not displayed when it is not necessary. Thereby, by always displaying the numerical value allowable range display 310, it is possible to prevent as much as possible that the entire screen becomes complicated and the display contents are overlapped, making it difficult to see.

  In the example shown in FIG. 5, the item setting of FIG. 3 is displayed among the items to be displayed (items where the item frame 210 is arranged on the screen) when a single numeric key is input on the key operation unit 7. Although an example of displaying the numerical value allowable range display 310 of all items set in the file has been shown, a dedicated key for displaying the numerical value allowable range display 310 instead of the numeric key input in the key operation unit 7 By providing and pressing the key, as shown in FIG. 5, the numerical value allowable range display 310 may be displayed for all corresponding items. Then, after confirming that the numerical value allowable range display 310 is displayed, a number may be input by operating a number key in the key operation unit 7.

  FIG. 6 is a display example on the pricing screen shown in FIG. In the example shown in FIG. 6, in addition to the numerical value allowable range display 310, a prohibition display 410 (410-1, 410-4, 410-7) is displayed. The prohibition display 410 indicates that the input (reflection) of the numerical value input in the input frame 201 to the item frame 210 is not permitted (the input of the numerical value input in the input frame 201 is prohibited to the item frame 210). Is notified. For example, the item frames 210-1, 210-4, and 210-7 are displayed such that “0-9” is displayed as the numerical value allowable range display 310 in each of the item frames 210-1, 210-4, and 210-7. Since the allowable number of digits is one digit ("0 to 9"), for example, when a two-digit numerical value "12" is input to the input box 201, as shown in FIG. The prohibition indications 410-1, 410-4, and 410-7 are displayed on 1, 2, 210-4, and 210-7, respectively.

FIG. 7 is a flowchart illustrating an example of an operation procedure of the label printer.
(Step S <b> 1) The operation control unit 24 of the control device 100 receives an operation input for displaying a pricing screen via the operation unit 5. The operation control unit 24 outputs an instruction signal for displaying the pricing screen to the CPU 20. The CPU 20 displays the pricing screen on the liquid crystal display 9b based on the instruction signal for displaying the pricing screen.

(Step S <b> 2) The CPU 20 reads a setting item file (see FIG. 3) from the RAM 30.
(Step S <b> 3) The CPU 20 determines whether or not a numerical value is input to the input frame 201. When a numerical value is input to the input frame 201 (step S3: YES), the CPU 20 advances the process to step S4. On the other hand, when a numerical value is not input in the input frame 201 (step S3: NO), the CPU 20 advances the process to step S8.

(Step S4) The CPU 20 determines whether or not the numerical value input to the input frame 201 is the first digit. When the numerical value input to the input frame 201 is the first digit (step S4: YES), the CPU 20 advances the process to step S5. On the other hand, when the numerical value input to the input frame 201 is not the first digit (step S4: NO), the CPU 20 advances the process to step S6.
(Step S5) The CPU 20 displays a numerical value allowable range display 310 in the vicinity of the item frame 210 that is the output destination of the input numerical value.

(Step S6) The CPU 20 determines whether or not the number of digits of the numerical value input in the input frame 201 is larger than the number of digits that can be input for each item of the item file. When the number of digits of the numerical value input in the input frame 201 is larger than the number of digits that can be input for each item in the item file (step S6: YES), the process proceeds to step S7. On the other hand, when the number of digits of the numerical value input in the input frame 201 is not larger than the number of digits that can be input for each item in the item file (step S6: NO), the CPU 20 advances the process to step S8.

(Step S7) The CPU 20 displays the prohibition display 410 in the item frame 210 in which the number of digits of the numerical value input in the input frame 201 is larger than the number of digits that can be input for each item in the item file.
(Step S8) The CPU 20 determines whether or not there is an end instruction. If there is an end instruction (step S8: YES), the CPU 20 ends the process. On the other hand, when there is no end instruction (step S8: NO), the CPU 20 returns the process to step S3.

  Here, an operation in which a numerical value input to the input frame 201 is output to the item frame 210 will be described. The operation control unit 24 of the control device 100 receives an input from an operator that specifies an output destination of a numerical value input to the input frame 201 via the operation unit 5. Here, one of the item frames 210 is designated as a numerical output destination. The operation control unit 24 outputs an instruction signal for inputting a numerical value to the designated item frame 210 to the CPU 20. The CPU 20 displays the input numerical value on the liquid crystal display 9b based on the instruction signal for inputting the numerical value to the item frame 210.

  However, when the operator gives an instruction to input a numerical value that does not satisfy the numerical value allowable range display 310 of the item frame 210, an error display is output and the input is not accepted. For example, if an instruction to input a 2-digit numerical value “12” is given to any of the item frames 210-1, 210-4, and 210-7, an input error is displayed and the input is not accepted.

  As described above, in response to an input from the operator, the control device 100 displays the numerical value allowable range display 310 and the prohibition display 410 in the item frame 210 in which numerical values are input, thereby inputting a numerical value that causes an input error. The possibility of being reduced can be reduced.

  As described above, when receiving a numerical value input from the operator, the control device 100 determines that there is an input error by displaying the numerical value allowable range display 310 in the item frame 210 specified as the output destination of the input numerical value. The item frame 210 not to be displayed can be shown to the operator. Therefore, the possibility that a numerical value that causes an input error is input can be reduced.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes designs and the like that do not depart from the gist of the present invention. For example, the numerical value allowable range display 310 may be provided with a dedicated key for receiving an input from the operator, and the numerical value allowable range display 310 may be displayed when the dedicated key receives an input from the operator. Moreover, in the said embodiment, if the numerical value by which the number of digits which can be input in each item is set in FIG. 3, the range information of "0-999999" was displayed. However, it is not limited to this. That is, for example, a product file is set in FIG. 2 and a product number from 0 to 999999 can be set. For example, if “000150” is set as a product number in the product file, Up to the maximum number of digits of the set product number may be displayed. In this example, 0 to 999 may be displayed. Further, the maximum numerical value of the set product number may be displayed instead of the maximum number of digits set. In the above example, 0 to 150 may be displayed. In other words, the numerical value allowable range information to be displayed may not be a number based on the information on the number of digits that can be input in each item number set in the item setting file of FIG.

Further, in the above embodiment, the input frame 201 in FIG. 4 is an example in which the field for displaying the product name and the field for displaying the numerical value when the numeric key is pressed from the key operation unit 7 are used as described above. Although shown, it is not limited to this. That is, a dedicated field for displaying the input numerical value may be provided. In this case, the name of the called product is always displayed in the input box 201 in the above embodiment, and the input numerical value is different from the input numerical value. It may be displayed in a dedicated column.
Further, in the above embodiment, when there are a plurality of item frames 210 that may be output destinations by inputting a one-digit numerical value in the input frame 201, as shown in FIG. The example which displays the numerical value tolerance range display 310 with respect to 210 at once was shown. In this way, by displaying numerical value allowance information for all possible item frames 210 as output destinations, all numerical value allowable range displays 310 can be visually recognized with a single operation. Is good but not limited to this. That is, when the item frame 210 that is the output destination of the input numerical value is limited, the numerical value allowable range display 310 for the limited item frame 210 may be displayed.

  Further, for the item name set in the item setting file of FIG. 3, only when the data in the item is set in the product in the product file in FIG. You may make it display. Specifically, since “2” is set as the subcode in the product number 000002 in FIG. 2, the product is called in the pricing mode in FIG. In this case, “0-9” is displayed as in the numerical value allowable range display 310-4. However, if no subcode data is set for the product 000002, the numerical value allowable range display 310- 4 may be controlled not to be displayed. In this way, it is possible to prevent a subcode from being input accidentally for a product for which no subcode is set.

Further, the numerical value allowable range display 310-4 displayed in FIG. 5 may be displayed for all items in which numerical values can be input in the pricing mode of FIG. More specifically, for example, in the setting mode for setting product file data and the like, if the subcode in FIG. 5 is set to “not used” for all products, the numerical value in FIG. “0-9” in the allowable range display 310-4 may be hidden. That is, for the items displayed in FIG. 5, there is a setting means for determining whether or not to accept numerical value input, and the numerical value allowable range display 310 is displayed only for the items for which input can be accepted by the setting means. Since the display is controlled, it is possible to prevent a numerical value from being erroneously input to an item that cannot be set on the pricing screen of FIG.
Additional notes are disclosed below.

According to one aspect of the present invention, there is provided display means for displaying a pricing screen including an input frame for displaying a numerical value input by an operator and an item frame as an output destination of the numerical value input to the input frame; and a predetermined operation And a control unit that causes the display unit to display numerical permissible range information for the item frame according to the control unit.
As a result, the control device can reduce the possibility of input of a numerical value causing an input error by showing the operator numerical value allowable range information of an item for outputting the input numerical value in the operator's input operation. Quick numerical input is possible. In this case, when there are multiple item frames that are the output destinations of the input numerical values, the numerical value allowable range information to be displayed is to display the numerical value allowable range information for all the item frames at a time. Alternatively, when the item frame that is the output destination of the input numerical value is limited, the numerical value allowable range information for the limited item frame may be displayed.
[Appendix 2]
In the control device, the predetermined operation may be an operation in which a numerical value of at least one digit is input to the input frame.
As a result, only by inputting at least one digit for inputting a numerical value, the numerical value allowable range information is displayed, so that the range can be confirmed immediately.
[Appendix 3]
In the control device, the control means may display the numerical value tolerance range information in the vicinity of the item frame.
As a result, it is possible to check the numerical value tolerance of the item frame in the vicinity of the item frame where the numerical value is to be input, reducing the burden of checking the numerical value allowable range, and the operator can quickly input the numerical value It can be performed.
[Appendix 4]
In the control device, the control means determines whether or not the input numerical value satisfies the numerical value allowable range information in the item frame every time a numerical value is input to the input frame. As a result of the determination, a prohibition display may be displayed in the item frame where the numerical value input in the input frame is not allowed.
As a result, it is possible to prevent the numerical value input in the input frame from being erroneously input to the item frame that has been prohibited. In addition, every time a digit is entered in the input frame, a prohibition display is made for the item frame that is out of the allowable range. It can be recognized that a numerical value outside the allowable range in the item frame has been input to the input frame. Therefore, the operator can recognize an error in numerical input at an early stage, correct the numerical value within the allowable range, and input it quickly.
[Appendix 5]
Another aspect of the present invention is a printer comprising the above-described control device and a printing unit that prints a print content including data input to the item frame on a medium in a predetermined format.
Thus, the printer can reduce the possibility that a numerical value that causes an input error is input by indicating to the operator the numerical value allowable range of the item for outputting the input numerical value in the input operation of the operator.

  The program for realizing the control device and printer described above is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into the computer system and executed, thereby executing the execution process. May be performed. Here, the “computer system” may include an OS and hardware such as peripheral devices.
