Description

TECHNICAL FIELD The present invention relates to a data input device used for an electronic quiche register (ECR) and the like.

[Prior Art] Conventionally, in a data input device such as ECR, a dot matrix type liquid crystal display panel is laminated under a touch panel in which a plurality of touch sensors (touch keys) are arranged in a matrix. The function names of the keys arranged on the touch panel are displayed as symbols on the liquid crystal display panel in correspondence with the touch keys assigned to the touch panel. In the touch-type key input device configured as described above, the function of each product-specific key arranged in a matrix can be switched in order to use the same key as a product-specific key for different products. There is something. That is, for example, if it is assumed that there are 4 × 5 = 20 product-specific keys arranged in a matrix on the touch panel and the number of products handled is 60, the function of each product-specific key can be switched twice. Even individual product-specific keys can function as product-specific keys for 60 items. That is, when the first 1 to 20th product is assigned to 4 × 5 = 20 product-specific keys (switching state of the first page), when the first function switching is performed, 4 × 5 = 20 product-specific keys are 2
Those functions can be switched as the 21st to 40th product-specific keys belonging to the page. Then, when the function switching is performed for the second time, each key belongs to the third page.
Those functions can be switched as the thirtieth to sixtyth product-specific keys.

[Problems to be Solved by the Invention] However, in this type of product, when the merchandise belonging to several pages ahead is registered instead of the merchandise belonging to the same page is continuously registered, the key Since it is necessary to switch the functions, there are drawbacks that the key operation becomes complicated and causes an erroneous input.

The present invention has been made in view of the above circumstances, and an object thereof is to prevent erroneous input and facilitate the function switching operation.

[Means for Solving the Problem] The keyboard 1 includes a plurality of input units and a display unit corresponding to the input units.

The classification attribute data storage unit 2 stores display data and a plurality of attribute data for each classification.

The attribute designating means 3 designates any one of a plurality of attribute data stored in the classification attribute data storage means.

The classification designating means 4 designates the classification corresponding to the attribute data designated by the attribute designating means.

The function switching means 5 switches a plurality of input sections arranged on the keyboard to a function for inputting data of each classification designated by the classification designating means.

The display control unit 6 displays the display data of the classification corresponding to the function of the input unit switched by the function switching unit on the display unit corresponding to the corresponding input unit.

[Operation] When any one of the plurality of attribute data stored in the classification attribute data storage means 2 is designated by the attribute designating means 3, the classification corresponding to the designated attribute is stored in the classification attribute data storage means 2. The input section of the keyboard 1 is switched by the function switching means to a function for inputting the data of each of the specified classifications designated by the classification designating means 4 from the stored classifications. Further, display data corresponding to the switched classification is displayed on the display unit of the keyboard 1 by the display control means 6.

Therefore, erroneous input can be prevented and the function can be easily switched.

[Embodiment] The present invention will be specifically described below based on an embodiment shown in FIGS. 2 to 6. It should be noted that this embodiment shows an example applied to the ECR for restaurant specifications.

Structure Figure 2 is a basic block circuit diagram of this ECR. 1 in the figure
1 is an input section of this ECR. On this keyboard 11-1, there are pushbutton type numeric keypad KA, cash / deposit key KB, subtotal key KC, clear key KD, product number input key KE, and mode switching. A switch MS and a touch key input device TK are provided. Here, the mode changeover switch MS is a control lock for changing over each mode of “setting”, “registration”, “power OFF”, “inspection”, and “payment” according to the switching position. As shown in FIG. 3, the touch-type key input device TK has a dot-matrix liquid crystal display panel MD laminated below a touch panel TP having a plurality of touch sensors (touch keys) arranged in a matrix. Place and
Corresponding to each touch key assigned on the touch panel TP, the function name of the key is symbolically displayed on the liquid crystal display panel MD. Here, in the present embodiment, 5 in the row direction and 7 in the column direction, a total of 5 × 7 = 35 touch keys T1 to T35 are provided as product-specific keys and also as other touch keys. Key TA by classification,
TB, TC, page switching key TD, classification data input key TE, function switching key TF are provided. Then, the key input signal output from the input unit 11 corresponding to the operation key is the CPU
It is given to (central processing circuit) 12 and specifies its input processing program.

The CPU 12 controls various operations of this ECR, and executes input processing, product-specific registration processing, and the like. The CPU 12 has a register 12-3 in which the input classification code is set, in addition to the arithmetic unit 12-1, the control unit 12-2, etc. which are normally provided.
With the configuration, the CPU 12 has a ROM (read-on memory) 1
3, a RAM (random access memory) 14, a display unit 15, a printing unit 16, and a drawer drive unit 17 are connected to each other.

The ROM 13 stores a control program for controlling the operation of this ECR and has a character generator. In addition, the RAM 14 is a product-specific memory 14-1,
The memory 12-2 has a classification memory 14-2, a link destination memory 14-3, and the like, and data writing and reading operations are controlled under the control of the CPU 12. Here, the product-specific memory 14-1 stores the character data indicating the product name, the number of units sold, and the unit price corresponding to each product code.
A flag for designating a plurality of classifications corresponding to each product code, in this embodiment, "Chinese", "Japanese food", and "noodles" is stored. The classified memory 14-2 stores the amount of sales and the number of sold products corresponding to the classification code of each classification. Further, the link destination memory 14-3 is a classification memory 14-corresponding to the classification of the product memory 14-1.
The link destination address of 2 is stored.

Operation First, a case will be described in which classification data is set in the product-specific memory 14-1 in order to specify the classification to which the product belongs in correspondence with each product in the product-specific memory 14-1. In this case, of the classification keys TA, TB, TC of the touch-type key input device TK, operate the classification key corresponding to the classification to which the target product belongs, and then operate the ten-key KA to enter the product number. Operate the product number input key KE. Then, the operation according to the flow of FIG. 4 is executed. That is, the corresponding product code is searched from the product memory 14-1 based on the input product number (step A1). As a result,
When it is detected in step A2 that the corresponding product code is not stored in the product-specific memory 14-1, an input error (step A3) occurs, but the corresponding product code is stored in the product-specific memory 14-1.
If it is stored in 1, the flag "1" is set to the corresponding classification of the corresponding product (step A4). Therefore, taking the product "ramen" as an example, the flag "1" is set corresponding to the categories "Chinese" and "Noodles" (see FIG. 2). When the classification to which each product belongs is designated and input in this way, the inputted classification data is written in the product-specific memory 14-1 for each product.

Next, the display operation on the liquid crystal display panel MD when the page switching key TD, the classification data input key TE, and the function switching key TF are operated will be described. FIG. 5 is a flow chart showing the operation in this case.

First, when the page switching key TD is operated, this is detected in step B6, and the process proceeds to step B7, where the character data (product name) for the next page is displayed on the liquid crystal display panel MD. That is, each product in the product-specific memory 14-1 is designated by one page (35 corresponding to the product-specific keys T1 to T35) from the product number "1", and the product name is designated by the product-specific key T1 to.
When the page switch key TD is operated in the state where it is displayed in the display area of the liquid crystal display panel MD corresponding to T35 (display state of the first page), 35 product names for the next page are displayed on the liquid crystal display panel MD. The display is switched to. Therefore, every time the page switching key TD is operated, the products in the product-specific memory 14-1 are sequentially designated one page at a time from the beginning, and the product names are switched and displayed one page at a time on the liquid crystal display panel MD. . As a result, when 14-0 product codes are set in the product-specific memory 14-1, the page switching key TD may be operated four times. When the display content (product name) of the liquid crystal display panel MD is switched in this manner, the product-specific key T1 provided on the touch panel TP corresponding to this is switched.
~ The input function of T35 is also switched.

Next, a display operation when the classification data input key TE is operated will be described. Now, it is assumed that the classification-specific data input key TE is operated after the classification-specific key TA corresponding to "Japanese food" is operated. When the classification data input key TE is operated, that is detected in step B1 and the process proceeds to step B2.
Based on the contents of the register R in which the inputted classification code is set, it is checked whether or not the flag of the corresponding classification is "1" from the leading product of the product-specific memory 14-1 (step B3). Since the Japanese food flag corresponding to the first product “Ramen” is “0”, the process returns to step B2, and the Japanese food flag of the product memory 14-1 is sequentially changed from the first product until the product having the Japanese food flag “1” is searched. Check the set status. Now, when the product with the Japanese food flag “1” is retrieved, the process proceeds to the next step B4, and the maximum number of display areas of the liquid crystal display panel MD is “35”.
If the result is "35" or less, the product name of the product searched this time is displayed in the next display area (empty area) of the liquid crystal display panel MD (step BT). Then, returning to step B2, the above operation is repeated until the product name for one page is displayed on the liquid crystal display panel MD.
However, when the product name for one page (35 items) is displayed on the liquid crystal display panel MD, this is detected in step B4 and the process exits from this flow. When the classification data input key TE is operated in this manner, products belonging to the specified classification are retrieved from the product-specific memory 14-1 and their product names are displayed, so that the products displayed on the liquid crystal display panel MD are displayed. All products for pages are related to Japanese food. Similarly, when noodles are designated, the products with the noodles flag “1” in the product-specific memory 14-1 are sequentially designated, and the product names are displayed. Therefore, as shown in FIG. 2, when the Japanese food and noodles flag is set to "1" corresponding to the product "Udon", the product "Udon" is displayed in the Japanese food display mode and the noodle display mode respectively. The product name is displayed. When the display content of the liquid crystal display panel MD is changed in this way, the functions of the product-specific keys T1 to T35 corresponding thereto are also switched, as in the case described above.

On the other hand, when the function switching key TF is operated, the fact is detected in step B8, the process proceeds to the next step B9, and the next function data is displayed. For example, when the function switching key TF is operated while the function data and the like are displayed on the liquid crystal display panel MD, the product name is switched to the display state and the like. 7 (A), (B), and (C) show the display state in this case, the display state shown in FIG. 7 (A) is the Japanese food mode, and the display state shown in FIG. 7 (B) is the character setting. The display state shown in FIG. 7C is the noodles mode.

When any key other than the page switching key TD, the classification data input key TE, and the function switching key TF is operated, another display process corresponding to the operation key is executed (step B1.
0).

Next, the commodity-specific registration operation will be described with reference to the flowchart of FIG. In the registration mode, check whether the product name to be registered is displayed on the liquid crystal display panel MD, and if not, operate the page switching key TD or the classification data input key TE until the desired product name is displayed. .
When the desired product name is displayed on the liquid crystal display panel MD, touch the display position with a finger or the like to display product-specific keys T1 to T35.
The corresponding product-specific key is turned on and the product code is input. Based on the product code input in this manner, the product memory 14-1 is searched for the corresponding product code (steps C1 and C2). When the input product is searched, the sales quantity corresponding to the product in the product memory 14-1 is incremented by "1", and the sales data is accumulated (step C3). Then, the character and unit price of the product are read from the product-specific memory 14-1 and the display unit 1
5, sent to the printing unit 16, displayed and printed (step C4). Then, based on the contents of the product-specific memory 14-1, the classification for which the classification flag of the corresponding product is set to "1" is checked, the link destination address corresponding to the classification is read from the link destination memory 14-3, and the The classification memory 14-2 is addressed, and the number of sales and the amount of sales corresponding to the classification are added (steps C5 and C6). Such an operation is executed every time the product-specific registration operation is performed, and as a result, the product-specific memory 14 is executed each time the product-specific registration is performed.
The number of sales in -1 is accumulated and the memory for each category 14
-The number of units sold and the amount of sales are accumulated.

EFFECTS OF THE INVENTION According to the invention of the present application, a plurality of attributes such as “Chinese”, “Japanese food”, and “Noodles” are provided for each product (classification) such as “Ramen” and “Udon”. Data is stored, and according to the designation of one of these multiple attribute data,
Since the display contents of the product-specific (classification) keys displayed are switched to those corresponding to the attribute, a plurality of product-specific keys arranged on the keyboard can be changed according to a preset order. The function can be switched as a product-specific key of an item, and can also be made to function as a product-specific key for each same attribute. Therefore, in restaurants, for example, the product “Ramen” can be input regardless of whether “Chinese” or “Noodles” is specified. Since it is possible to easily switch the functions, and also the functions can be switched for each attribute, it is possible to effectively prevent erroneous input.
