TECHNICAL FIELD OF THE INVENTION
The present invention relates to a handy terminal used by a user to collect various data while carrying it.
[0002]
[Prior art]
The handy terminal is equipped with a group of keys including numeric input keys, which are used by the operator to collect data, for example, to record the number of goods in the warehouse during inventory, or to record the number of cases. Used for Then, the data recorded in the handy terminal is transferred to the host computer and is centrally managed by the host computer.
[0003]
To explain an example of a work using a conventional handy terminal, for example, when it is desired to record the number of products stored in case units, an operator first counts the number of cases, and then manually calculates the number of cases. The calculator calculates the number of products using a calculator, and inputs the calculation result to the handy terminal using keys.
[0004]
As another example, when inputting the price of a product into a handy terminal, a calculator is used to calculate the price and the number, and the calculation result is key-input to the handy terminal.

The work was complicated. In addition, since it is necessary to input a key to the handy terminal while observing the calculation result displayed on the display unit of the calculator, when inputting a numerical value to the handy terminal, a mistake is likely to occur due to misunderstanding or the like. .
[0009]
Therefore, an object of the present invention is to provide a handy terminal that can simplify the operation of inputting a numerical value of the handy terminal.
[0010]
It is a further object of the present invention to provide a handy terminal capable of assisting the calculation of the number of commodities when inputting a numerical value of the handy terminal.
[0011]
[Means for Solving the Problems]
According to the present invention, such a technical problem
An input unit having a key and / or a touch panel and a display unit, and a numerical value input by the input unit when a numerical value input screen is displayed on the display unit in a numerical value input mode is determined. In the handy terminal that records the confirmed input value,
The handy terminal further has a calculator mode functioning as a calculator,
When transitioning from the numerical value input mode to the calculator mode by operating the input unit, the numerical value input to the numerical value input screen in the numerical value input mode is temporarily stored in the internal memory, and this numerical value is stored. Set as the input value of the calculator mode,
When this is determined after the calculation in the calculator mode is completed, the calculation result is temporarily stored in the internal memory, the calculator mode returns to the numerical value input mode, and the numerical value of the calculation result is set in the numerical value input mode. This is achieved by providing a handy terminal characterized by being set as an input value.
[0012]
According to the handy terminal of the present invention, the mode is switched from the numerical value input mode to the calculator mode and from the calculator mode to the numerical value input mode only by operating the input section of the handy terminal such as a key operation. Then, when the mode is switched, the value before the switching is set as the input value after the switching, so that it is not necessary to input again when the mode is switched. That is, at the time of switching from the numerical value input mode to the calculator mode and at the time of switching from the calculator mode to the numerical value input mode, the numerical value before the mode switching is reflected as the input value in the mode after the switching.

The table 30 also has a communication interface control and processing unit 302 for communicating with the host computer, and the handy terminal 1 is placed on the table 30 so that the optical communication window 31 ( It can communicate with the host computer using the light receiving / emitting element 303 installed facing the infrared transmitting filter).
[0024]
The handy terminal 1 has a calculator function. That is, a calculator program for executing the four arithmetic operations is stored in the ROM 201 of the handy terminal 1, and the calculator function uses the handy terminal 1 by pressing down the function key 16 and selecting the calculator mode. When the enter key 14 is depressed, the calculation result is recorded in the RAM 202 of the handy terminal 1 and the numerical value is set as an initial value of the numerical value input mode and displayed on the display unit 7.
[0025]
The operation and the operation of the handy terminal 1 when inventorying the number of commodities contained in the case from the number of cases stored in the warehouse using the handy terminal 1 of the embodiment will be specifically described. When the product code is input to the handy terminal 1 by reading the bar code, this product code is recorded in the RAM 202, the handy terminal 1 enters a numerical value input mode, and the display 7 displays the number of cases to the operator. A numerical value input screen D1 (FIG. 6) for requesting an input is displayed. The worker counts the number of cases in the warehouse. For example, if the number is “12”, the operator inputs the number of the products using the ten keys 15.
[0026]
D2 in FIG. 6 shows a numerical value input screen when the number of cases has been input. When it is desired to use the calculator function of the handy terminal 1 to calculate the number of commodities contained in the case from the number of cases, a key for shifting to the calculator mode, for example, the F1 key 16 may be depressed. Thereby, the handy terminal 1 transits to the calculator mode, and executes the four arithmetic operations by the same operation as the normal calculator.
[0027]
D3 in FIG. 6 shows the display screen before the start of the calculation in the calculator mode. When shifting to the calculator mode, the numerical value (“12” in this example) for which numerical input has been completed on the numerical value input screen D2 immediately before that is temporarily stored in the RAM 202 when switching to the calculator mode by operating the F1 key 16. This numerical value is set as an input value in the calculator mode, and is displayed on the calculation start screen D3. That is, the calculation start screen D3 is displayed in a state where a numerical value is input.
[0028]
The operator selects "x" by key operation, and then inputs the number of commodities contained in one case by keying, and the handy terminal 1 executes multiplication and displays the calculation result (D4). . When the operator completes the calculation in the calculator mode, the operator depresses the enter key (for example, the ENT key 14), the handy terminal 1 escapes from the calculator mode, returns to the numerical value input mode, and the screen of the display unit 7 displays the numerical value. The screen switches to the input screen.
[0029]
When exiting from the calculator mode, the numerical value of the calculation result is temporarily stored in the RAM 202, the calculation result is set as an input value in the numerical value input mode, and the calculation result obtained in the calculator mode is input to the numerical value input screen D5. It is displayed in the state where it was done. Therefore, the operator presses down the ENT key 14 to determine the quantity, and the quantity of the product is recorded in the handy terminal 1 (RAM 202).
[0030]
Note that it is convenient to be able to cancel in the middle of the calculator mode. For example, if the cancel key 13 is depressed in the middle of the calculator mode, it is preferable to return to the numerical value input screen D2 immediately before entering the calculator mode. .
[0031]
Although the preferred embodiment of the present invention has been described above, a touch panel may be provided on the display unit 7 of the handy terminal 1 so that four arithmetic operations (×, ÷, +, −, =) can be input on the touch panel. . In addition, four arithmetic operations (×, ÷, +, −, =) and the “MR”, “MC”, and “M +” functions of the calculator may be assigned to various keys of the key input unit 9 of the handy terminal 1.
[0032]
By adding the “MR”, “MC”, and “M +” functions of the calculator to the calculator mode of the handy terminal 1, for example, by repeating addition and multiplication in the calculator mode, the total amount or discount amount of the product can be determined by a series of operations. You can ask.
