Description

TECHNICAL FIELD The present invention relates to a data input device used for inputting numerical data.

[Prior Art] In a data input device having a keyboard provided with numerical keys for inputting numerical data and function keys for instructing the processing of the numerical data, a data input device is operated by inputting numerical keys. A numerical register for storing the input numerical data in the order of input is provided, and the numerical data stored in the numerical register is processed based on an instruction from the function key.

In such a device, a function of checking whether or not the numerical data stored in the register is an integer multiple of an arbitrary numerical value has been known (Japanese Patent Laid-Open No. 58-16).
No. 9671, etc.), there is no function for checking whether or not the same numerical data is continuously stored. For this reason, even if the operator makes an operation error such as pressing the same number key continuously, so-called double typing error, and the same numerical data is input continuously, the numerical data is treated as valid. It had been.

It is known that, in a data input device for inputting barcode data, a warning is issued to alert an operator when the same barcode data is continuously input (Japanese Patent Laid-Open No. 1-169696). Issue). However, in this case, the numerical data before data processing is stored, which is the collation of the barcode data that was previously input and has already been processed, and the barcode data that was input this time and is not yet processed. This is fundamentally different from checking whether or not the same numerical data is continuously stored in the number register.

[Problems to be Solved by the Invention] As described above, in the conventional data input device used for inputting numerical data, it is checked whether the same numerical data is continuously stored in the number register. Since there is no such function, even if the same numerical data is continuously input due to an operator's operation error, the numerical data is processed as valid.

Therefore, according to the present invention, when the same numerical data is continuously stored in the numerical register, the operator can be warned to call attention, and error data due to an operation error such as a double tap error can be processed. It seeks to provide a data entry device that can be disabled before.

[Means for Solving the Problems] The present invention provides a keyboard provided with numerical keys for inputting numerical data and function keys for instructing processing of the numerical data, and input of numerical keys. A data input device that has a numerical register that stores numerical data input by operation in the order of input, and that processes numerical data stored in this numerical register based on instructions from function keys And a judging means for judging whether or not the same numerical value data is continuously stored in the numeral register, and an alarm is output when it is judged by this judging means that the same numerical value data is continuously stored. The alarm output means, a selection means for selecting whether to validate or invalidate the numerical data output by the output means, and the selection means. A unit for clearing the number of registers that clears the contents of the number register when invalid is selected.

[Operation] According to the present invention having such a configuration, when the operator performs an input operation on the numeric key, the numerical data corresponding to the input key is stored in the numeric register in the order of input. After that, for example, when an operator inputs a function key to instruct the processing of numerical data, it is checked whether the same numerical data is continuously stored in the above register in response to the input of the function key. To be done. Then, when the same numerical data is continuously stored, a warning is issued. Here, when the operator selects the validity of the numerical data by the selection means, the numerical data stored in the numerical register is processed based on the instruction of the corresponding function key.

On the other hand, when the invalidation of the numerical data is selected, the numerical data stored in the numerical register is cleared. Therefore, when the same numerical data is continuously input by double typing by the operator, an alarm is always issued, so by selecting invalid numerical data, the numerical input data that is erroneously input is processed. You can prevent it in advance.

[Embodiment] An embodiment in which the present invention is applied to a portable ordering terminal used for product ordering work in a store will be described below with reference to the drawings. In addition to the product ordering work, this ordering terminal is capable of executing various works such as setting work such as date and time and writing work to the store controller.

FIG. 1 is a perspective view showing an external configuration of the ordering terminal. The power switch 2 is provided on the right side surface of the housing 1, and the keyboard 3 and the liquid crystal display 4 are provided on the upper surface.

36, various keys such as the "#" specific key 37 and the like.

The liquid crystal display 4 can display a screen with a maximum of 8 lines vertically and 24 characters horizontally.

FIG. 2 is a control block diagram of the ordering terminal, in which a CPU (central processing unit) 11 serving as a control unit main body stores a storage unit of ROM 13 and RAM 14 via a bus line 12 and a clock circuit for measuring the present time. 15, a buzzer circuit 17 for driving a buzzer 16 that emits an error sound and a warning sound, the keyboard 3
A keyboard circuit 18 to which a key signal is input from, a display control circuit 19 that outputs display data to the liquid crystal display 4, a communication interface 20 that transmits and receives data to and from the outside are connected.

Fixed data such as program data is stored in the ROM 13.

As shown in FIG. 3, the RAM 14 stores individual product data such as product code, product name, sales record, ordering unit, minimum ordering number, etc. of each product belonging to the classification code for classifying each product handled in the store. Preset Product Table 14
1, a classification table 142 in which the classification name and the number of products for each classification code are preset, a numerical register 143 that stores numerical data in the order of input, an area 144 of a numerical counter N that counts the number of input digits of numerical data, and an order Order registration buffer that stores the product code of each product whose number is registered and the number of orders
145, an area 146 of a registration number counter M for storing the number of registrations in the buffer 145, areas 147, 148, 149 of a first counter A, a second counter B and a flag F used for collation processing of numerical data described later. Has been formed.

The RAM 14 is backed up by a battery (not shown). Further, the preset processing of the single item data for the product table 141 and the classification data for the classification table 142 is performed at an appropriate time by an external device electrically connected via the communication interface 20 when the setting operation is selected. Here, the sales record is a score of the corresponding product sold from the time of the previous order to the present. The ordering unit is the unit number of one ordering order for the corresponding product. The minimum number of orders is the minimum number of orders for the corresponding product once.

When the power switch 2 is turned on, the CPU 11 causes the liquid crystal display 4 to display a menu screen for selecting the above-mentioned work. In this state, when the product ordering work is selected by the key operation, the program is controlled so as to execute the processing shown in the flow chart of FIG. 4A.

That is, first, as ST (step) 1, the order registration buffer 145 of the RAM 14 is cleared and the registration number counter M of the area 146 is initialized to "0". Next, as ST2, a classification screen display process is performed on the liquid crystal display 4. This classification screen display process is a process of displaying the classification code, classification name, and number of products set in the area indicated by the table pointer of the classification table 142. The table pointer is 1 point when the downscroll key 33 is input. When moving backward and inputting the up scroll key 34, 1
The point is designed to move forward. After the power switch 2 is turned off, the current value is held.

In this state, when the registration key 32 is operated as an input in ST3, a single item screen display process is performed on the liquid crystal display 4 as ST4. In this single-item screen display processing, the product table 141 of the classification code set in the area indicated by the table pointer of the classification table 142 is extracted, and the product code set in the area indicated by the table pointer of the product table 141,
In the process of displaying the product name, sales record, order unit, and minimum order number on the liquid crystal display device 4, the table pointer of the product table 141 has an initial value of "1", and then the down scroll key 33 is operated. It moves backward by one point and moves forward by one point when the up scroll key 34 is operated for input.

In this state, if the cancel key 35 is input in ST5, the process returns to the classification screen display process in ST2.

On the other hand, when the registration key 32 is input in ST6, the order quantity registration process shown in FIGS. 4B and 4C is executed. That is, the number register 143 is cleared and the number counter N is initialized to "0" to wait for the next key input.

If the numeric key 31 is operated as an input in ST7, the numeric counter N is updated by "+1", and the least significant digit R (0) of the numeric register 143 is input to the numeric key 31. Store the numerical data to be used. The contents of the numeral register 143 are displayed in a predetermined area of the liquid crystal display 4 and the next key input is awaited. If the numeric key 31 is also input next time, after updating the numeric counter N by "+1", the content of the least significant digit R (0) of the numeric register 143 is changed to the high digit R (1).
The numerical data input this time is stored in the least significant digit R (0) that has become an empty area. Also register register
Display the contents of 143 in a predetermined area of the liquid crystal display 4,
Wait for the next key input. In this way, every time numeric data is continuously input by the numeric key 31, the numeric counter N is updated by "+1", and then the content of the numeric register 143 is sequentially shifted to the upper digit to set an empty area. The lowest digit R
The numerical data input this time is stored in (0). Then, the contents of the numeral register 143 are displayed in a predetermined area of the liquid crystal display 4 and the next key input is awaited. However, if the number counter N exceeds the maximum digit number "8" of the number register N, the input of the number key 31 is ignored as an error.

There is no input of the numeric keypad 31 at ST7, and the registration key as ST8
If 32 is operated, this registration key 32 is a numeric key
Since the numerical data entered by 31 was entered as a function key for registration processing as the number of orders,
Product table 141 extracted in the single product screen display process
The minimum order number and the order unit set in the area indicated by the table pointer are compared with the numerical data in the number register 143. Here, if the numerical data is less than the minimum order quantity, or is more than the minimum order quantity but is not a positive multiple of the order unit, the order quantity for the product is not set as specified, so the registration key 32 Input error.

On the other hand, when the numerical value data is equal to or higher than the minimum order and is a positive multiple of the ordering unit, the numerical value data collating process from ST9 onward is executed because the ordering number for the product has been set. That is, as ST9, the flag F of the area 149 is reset to "0". Also, as ST10 area
It is assumed that the first counter A of 147 is a value obtained by subtracting “1” from the count value of the number counter N. Furthermore, as ST11, area 14
The second counter B of 8 is a value obtained by subtracting “1” from the count value of the first counter A. Then, as ST12, the numerical data of the digit R (A) corresponding to the first counter A of the number register 143 is checked. Then, if the numerical data is "0", the flag F is checked as ST13. Flag F here
Is reset, the first counter A is set to "-
After counting down "1", return to ST11.

On the other hand, in ST12, when the numerical data of the digit R (A) corresponding to the first counter A of the number register 143 is other than "0", the flag F is set to "1", and then the process goes to ST14. move on. Further, if the flag F is set in ST13, the process proceeds to ST14.

In ST14, the first counter A of the number register 143
Numerical data of digit R (A) corresponding to
The numerical data of the digit R (B) corresponding to the second counter B of 3 is compared (determination means). If they do not match, the first counter A is counted down by "-1", and then the count value of the counter A is checked in ST15.
If the count value of the counter A is larger than "0", the process returns to ST11.

When the count value of the first counter A becomes “0” in ST15, the same numerical value data is not continuously stored in the register number register 143.
Is updated by “+1”, and the product code and the number of products set in the area indicated by the table pointer of the product table 141 extracted in the single product screen display process are displayed in the area corresponding to the address M of the order registration buffer 145. Registration processing is performed with the numerical data (number of orders) in the buffer 143. After that, the table pointer of the product table 141 is updated by "+1", and the process returns to ST4.

On the other hand, in ST14, the digit R (A) in the number register 143
When the numerical value data of 1 and the numerical value data of the digit R (B) match, the same numerical value data is continuously stored in the register number register 143. Therefore, the buzzer circuit 17 is controlled and the buzzer 16 is turned on. Sounds (alarm output means) and waits for the next key input. If the cancel key 35 is input at ST16, the invalidation of the numerical data is selected. Therefore, the contents of the numerical register 143 are cleared and the numerical counter N is initialized to "0" (setting Wait for the next key input. If the numeric key 31 is pressed, the above-mentioned ST7
If the registration key 32 is input after performing the following processing,
The processing after ST8 is executed. Also, in ST7, the numeric key
If there is no input of 31 and the registration key 32 is not input in ST8 and the cancel key 35 is input in ST17, the table pointer of the product table 141 is updated by "+1" and the process returns to ST4.

On the other hand, there is no input of the cancel key 35 in ST16, and ST18
When the registration key 32 is input as, the registration number counter M in the area 146 is updated by "+1" because the registration data 32 is selected to be valid, and the area corresponding to the address M in the order registration buffer 145 is updated. Then, the product code set in the area indicated by the table pointer of the product table 141 extracted in the single-item screen display process and the numerical data (number of orders) in the number buffer 143 are registered. After that, the table pointer of the product table 141 is updated by "+1", and the process returns to ST4.

Therefore, the registration key 32 and the cancel key 35 function as selection means for selecting whether to validate or invalidate the numerical data output by the buzzer 16.

The buzzer 16 stops in response to the next first key input or after a certain period of time has elapsed.

In the order number terminal of the present embodiment configured as described above, when performing an ordering operation for a certain product, the operator, after turning on the power switch 2, looks at the classification data screen displayed on the display 4 and scroll keys. Operate 33 or 34 to select the classification data to which the ordered product belongs.
When the corresponding classification data is displayed on the display 4, the registration key 32 is operated. Then, display 4
Is switched to the single item data screen of the corresponding classification code, the scroll key 33 or 34 is operated while viewing the screen to select the order target product. When the individual product data such as the product code, product name, sales record, ordering unit, minimum ordering number, etc. of the product to be ordered is displayed, the registration key 32 is first operated. Next, after inputting a numerical value which is equal to or more than the minimum order number displayed and which is a positive multiple of the order unit from the numeric key 31, the registration key 32 is operated again. Then, it is determined whether or not the same numerical data is continuously stored in the numeral buffer 143.

Here, for example, when the numerical data stored in the numerical register 143 is “123” or the like, since the same numerical data is not continuously stored, the contents of the numerical buffer 143 is the ordering number. Registration processing is performed in the order registration buffer 145 together with the product code of the product.

On the other hand, for example, when the numerical data stored in the numerical register 143 is “112”, “122”, “111”, etc.,
Since the same numerical data is continuously stored, the buzzer 16 produces an alarm sound.

Therefore, the operator confirms the input data of the ordered quantity displayed on the display unit 4. Then, when the desired order quantity is correctly entered, the registration key 32 is operated. By doing so, the contents of the number buffer 143 are registered in the order registration buffer 145 together with the product code of the product as the number of orders.

On the other hand, if the desired order quantity has not been accurately entered due to an operation error such as double-strike of the numeral keys 31, the cancel key 35 is operated. By doing so, the contents of the number input buffer 143 are cleared, and the number of orders can be input again.

In the conventional ordering terminal of this type, even if the ordering number is erroneously input, an alarm is not issued as long as the ordering conditions such as the minimum ordering number and the ordering unit are met. For this reason, the operator can
There was a problem that I entered 32 and registered the wrong number of orders.

On the other hand, in the case of the ordering terminal of the present embodiment, for example, when the user has to enter "12" as the number of orders, "112" or "122" can be entered by double-pressing the numeric key 31.
If the user mistakenly inputs such as, an alarm sound is emitted by the buzzer 16 to alert the operator. Therefore, it is possible for the operator to be aware of erroneous input and to prevent the problem that the wrong number of orders is registered in the order registration buffer 145 by operating the cancel key 35. It should be noted that even if the desired number of orders is the same numerical value such as "112", "122", "111", etc., a warning sound will be emitted, but by operating the registration key 32, the numerical value can be changed. Since the data can be registered effectively, there is no particular problem.
In addition, for example, even in the work of setting the date and time, the numeric keypad 31 is operated to input numerical data, but at this time, even if the above-mentioned double striking check is performed, it is configured not to be performed again. It doesn't matter.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, after inputting the numeric data by the numeric key 31, it is checked whether the same numeric data is continuously stored in the numeric register 143 in response to the input operation of the registration key 32 as the function key. However, each time the numeric key 31 is operated for input, the numerical data input immediately before is compared with the numerical data of this time, and an alarm is issued if the two match. Good.
Further, it goes without saying that the present invention is not limited to the ordering terminal and can be applied to all data input devices for inputting numerical data. In addition, it goes without saying that various modifications can be made without departing from the spirit of the present invention.

[Effects of the Invention] As described in detail above, according to the present invention, when the same numerical data is continuously stored in the number register, the operator can be warned to call attention. It is possible to provide a data input device capable of invalidating error data due to an operation error such as a double hitting error before data processing.
