Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stored program type data input device, and particularly to a general-purpose data input device that can handle even complex general-purpose data input.

In conventional data input devices using keyboard input, each program for a predetermined task is installed in advance, and by specifying the task using a function key, the data input procedure for that task and the number of digits of input data can be checked. and was performing the desired business process.

Therefore, it cannot be used for anything other than pre-programmed tasks, and has a major drawback of lack of versatility. Furthermore, since it is necessary to store programs for multiple tasks, a large area of program memory is required. Also,
This required a large number of function keys for specifying tasks and function keys for assigning meaning to item data.

In other words, the closer you try to make it to a general-purpose machine, the higher the cost and the physical impossibility. He was faced with the contradictory proposition that his character as a person would become stronger.

In view of the above points, it is an object of the present invention to solve these problems all at once, and to provide a versatile and low-cost general-purpose data input device.

In order to achieve such an objective, the present invention
A keyboard for inputting a task identification code given to each of a plurality of predetermined tasks, item data of a plurality of items whose input order is determined for each task, and the number of items of item data constituting one block; ,
A program memory that stores programs for performing general-purpose data input processing for each business;
As the business identification code is input using the keyboard according to the program and the number of items is input using the keyboard, this number of items is stored in a register, and the contents of this register and the number of item data repeatedly input from the keyboard are When they match, it is determined that the input for one block has been completed, and the central processing unit similarly repeats the input process for the item data composing the next block, and the input business identification code, the number of items, and the repeatedly input item data. Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a general-purpose data input device according to the present invention, and shows an example in which the present invention is applied to a portable data input device. In the figure, KB is a keyboard for inputting general-purpose identification data, the number of repeated items of general-purpose data, and general-purpose data, respectively.This keyboard KB is equipped with a numeric keypad and a function key, and the function keys include at least a start key, an enter key, an end key, There's a key. The start key is configured to specify/start a task together with a two-digit number, the enter key is configured to specify a category (item) of general-purpose data, and the end key is configured to specify the end of a task. There is. Other functions include a CE key for clearing numbers and resetting errors, and a month/day key for registering/confirming the year, month, and day, and specifying memory clear.

PM is a program memory that stores a program for processing data input from this keyboard KB, CPU is a central processing unit that repeatedly inputs general-purpose data according to a data processing program, and DM is a program memory that stores a program for processing data input from the keyboard KB. This is a data memory that stores general-purpose identification codes and item numbers as well as general-purpose item data input repeatedly. PRT is a printer that prints out the processing output of the central processing unit CPU via the input/output circuit I/O, and DP is a display that similarly displays the processing output of the central processing unit CPU via the input/output circuit I/O. .

Since the embodiment shown in FIG. 1 is portable, it also includes a battery BAT for backing up the data memory DM, a connector CN ₁ for connecting a charger CG for charging the battery BAT, and a data It is equipped with a connector CN ₂ for connecting the base unit to transfer data stored in the memory DM to the base unit MS. Figure 2 is a flowchart of the processing status by the central processing unit CPU, in which it is determined whether it is a numeric key input according to the output of the keyboard KB, and if it is YES, a shift register is configured in the central processing unit CPU. "Set to" temporarily stores all input data, and if "Numeric key input?" is NO, similarly determines "Start or Enter key input?" and selects YES for this.
According to the contents of the data memory DM, check whether the business's identification code has been written, and select NO.
In this case, the temporarily stored business identification code is stored and registered in the data memory DM by "Storing the contents of the shift register in memory".

Also, "Has the identification code been written?" is YES.
If so, check "Number of items written?" for one block according to the contents of the data memory DM,
If this is NO, the number of items for one block temporarily stored by the shift register can be stored in the A and B registers, which are configured in the same way as the shift register, by "Storing the contents of the shift register in the A and B registers". The data is stored in the register, a display signal is sent to the display DP, and the message "Enter first item data" is displayed by "display guide (H ₁ ) on display".

On the other hand, if "Number of items written?" is YES,
"Storing the contents of the shift register to memory" stores the input data temporarily stored by the shift register in the data memory DM as item data, and finally stores it.
=A-1", add "1" to the display of (H ₁ ) by "Add 1 to the guide display on the display", and check the contents of the A register by "A=0?" However, while this is NO, the process returns to "Numeric keypad input?" and repeats the same process.

Next, if "A=0?" becomes YES, it is determined that the number of items matches the number of repeatedly input item data, and all the item data of the number of items that make up one block have been input. "Set the contents of register B to register A"
Accumulate the number of items in the A register again, perform the "guide (H ₁ ) display on the display" in the same way as above, prepare for the input operation of the next block, and then press "Numeric keypad input?" Repeat and perform the same input processing.

For the above, "Start or Enter key input?"
If NO, it is determined whether the end key is input, and the series of input processing is completed in response to YES.

Therefore, after inputting the business identification code assigned to each job using a multi-digit number, etc., and then inputting the number of items of item data constituting one block, the item data for one block can be determined. If input is made in accordance with the input order set, these are sequentially stored in the data memory DM, and this input processing is sequentially repeated for each block.

In addition, since the number of items in one block of the central processing unit CPU naturally differs depending on the job, and the number of digits of item data also differs, data digit number monitoring checks for 9 or more digits in common item data and indicates an error. . Additionally, the number of digits in the identification code is checked.

FIG. 3 is a configuration diagram showing another embodiment of the present invention,
This shows the block configuration in the case of a hardware configuration. In the figure, TK is the numeric keypad on the keyboard, FK is the function key on the keyboard, CONT is the control unit, and this control unit CONT corresponds to the central processing unit CPU, program memory PM, and data memory DM shown in Figure 1, and the display vessel
It also includes DP. RG ₁ is B, which will be described later.
The output of the register is input, and the function key
An A register (subtraction counter) whose subtraction is controlled by a subtraction command from the FK (enter key), and this A register _RG1 is configured so that writing and clearing are controlled by a control unit CONT. RG ₂ is a B register for latch which receives the output of the numeric keypad TK as input, and this B register RG ₂ is configured so that reading, writing and clearing are controlled by the control unit CONT.

Next, the operation of this apparatus will be explained using the operation flowchart shown in FIG. In FIG. 4, the function key indicates the start key, and the function key indicates the enter key.

First, after turning on the power and checking, input the identification code of the desired business. For example, if you want to perform "ordering work", enter "01" from the numeric keypad and operate the start key.

On the other hand, the input order of item data is predetermined for each task, and is generally configured to be input in order of frequency of use. Therefore,
Assuming that the input format for “ordering operations” is also agreed to be in the order of product code, quantity, unit price, discount rate, size, color, season number, material, and weight, it is necessary to repeatedly input the item data up to the current number. Specify using the numeric keypad. As shown in FIG. 4, when repeatedly inputting the product code and quantity, "2" is input as the number of items data indicating the number of items for one block, and the enter key is operated.

Then, in response to the outputs of the numeric keypad TK and function key FK, the control unit CNT changes the B register.
To control RG ₂ and A register RG ₁ , the number of items is stored by B register RG ₂ and its contents are sent to A register RG ₁ , where the number of items is also stored.

Further, the following display is performed by the display device DP in the control unit CNT.

By operating the enter key, "H ₁ " indicating "input first general-purpose data" is displayed on the leftmost two digits of the display DP (8 digits). Then, following this guidance display, input the product code and operate the enter key. After pressing the enter key, "H ₂ " is displayed on the display DP, and the quantity data is input and the enter key is pressed. Here, since the specified number of repeated items is "2", when the input of quantitative data is completed, the guidance display becomes "H ₁ " again, and data input is repeated in the same manner as described above.

In other words, A register RG ₁ performs subtraction every time data is input according to the output of function key FK, and if the content becomes zero and the number of items matches the number of repeatedly input item data, then ,1
The item data for the block has been inputted, and the contents of B register RG ₂ are transferred to A register again.
RG ₁ and is stored again in A register RG ₁ , thus preparing the next block for input operation.

When all data input is completed, the user operates the end key to end the job. The input identification code data, repeat item number data, product code, and quantity data are stored in the data memory DM according to a predetermined format, and then transferred to the central master unit MS for transmission.

In this way, since guidance is displayed on the display DP, it is clear at a glance what data number to input.

Note that the input data is monitored on the display device DP. It can also be output using a printer PRT if necessary.

On the other hand, if the user wishes to perform another business process, the user inputs the identification code of the desired business and data on the number of repeated items, and performs the same operation as described above. Incidentally, in a certain task, when the number of repeated items is "4", if the third item data does not need to be input, it is sufficient to press the enter key blankly at "H ₃ ". For example, when performing the "attendance management work" shown in FIG. 4, that is, when the attendance code indicates absence, it is sufficient to press the function key four times. Alternatively, a return key may be provided to directly return to "H ₁ ".

Although the present invention has been described above with reference to an example in which the present invention is applied to a portable data input device, the present invention is not limited to this, and may be any device as long as it inputs data using a numeric keypad. Further, in the above embodiment, the identification code is input using the start key, but it may be input using the enter key. Further, although "H" is commonly used as a guide display, different identification symbols may be displayed for each task.

As is clear from the above description, the present invention has high versatility and can handle complex general-purpose data input, and also has a large program memory area and a large number of function keys. The practical effect is extremely large, since the cost can be reduced without requiring the above. Furthermore, since all business data can be input using the same operation, it is extremely effective in improving operability.
