Abstract

PURPOSE:To facilitate an operation by holding a calculation result obtained by an electronic calculator function in a part of a data area, and allowing a control program to be executed next to utilize the arithmetic result when necessary. CONSTITUTION:This device operates normally in a data input/output mode, and when an electronic calculator key on a keyboard 1 is pressed, the operation is shifted to an electronic calculator function program 5 through the operation of an operating system. The electronic calculator function program 5 after completing a series of operations stores the arithmetic result in a working area 7a and finishes the operation. When an electronic calculator data fetch key on the keyboard 1 is pressed when the operation mode returns to the original input/output control program 4, a control part 7 reads the data stored in the working area 7a and the data is processed equally to the data inputted from the keyboard 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a portable terminal device with a built-in calculator function. This type of device is used separately from the data processing device at the center, and allows data to be manually operated at a remote location. It also has calculator functions such as four arithmetic operations.

Conventionally, in this type of device, a control program for data output and an execution program for the calculator function existed independently, and only one of the programs was executed by changing a switch. That is, when the terminal device is used as a calculator, it is switched to the calculator mode with a switch, and the calculator function execution program is executed.When the terminal device is used as a data input/output device, it is switched to the calculator mode by changing the switch. This took the form of using a control program.

In other words, there was no relationship between the calculator function execution program and the human output control program.

Therefore, for example, in order to input the calculation result obtained by executing the calculator function execution program as one of the input data of this device whose switch is set as an input/output device, the operator records the calculation result on paper etc. This has the disadvantage that the operation is complicated because the key-in has to be input again into the device.

Therefore, an object of the present invention is to facilitate operations for inputting calculation results as data.According to the present invention, the calculation results calculated by the calculator function are held in a part of the data area. A portable terminal device is obtained in which the control program to be executed next can utilize the calculation results as necessary.

Next, the present invention will be described in detail with reference to the drawings showing one embodiment of the present invention.

In FIG. 1, the portable terminal device includes a keyboard 1 for inputting data. A display section 2 for displaying data and a printing section 39 A program memory 6 that stores the human output control program 4 and a calculator function program 5, a data storage section 7 that stores manually entered data, and a control section 8 that controls each of these sections. has. Further connected to the control unit 8 is an interface 9 for connecting this input/output device to a data processing device at the center.

The control unit 8 executes the human output control program 4 or the 'calculator function program 5' on the program memory 6 according to the designation from the keyboard 1, and causes this device to function as a data input/output device or a calculator.

That is, programs 4 and 5 are placed on the same level based on the same operating system.

A part of the data storage section 7 is a work area 7 that stores calculation results when this device functions as a calculator.
Used as a.

When this device functions as an input/output device, data is input from the keyboard 1, stored in the data storage section 7 by the control section 8, and outputted to the display section 2 and/or the printing section 3. The data stored in the data storage section 7 is sent to a processing device by an operator taking this device back to an office or the like and connecting it to the data processing device main body via an interface 9, where it is subjected to processing such as aggregation. .

When this device functions as a calculator, an arithmetic expression is entered manually using the numerical keys and operator keys on the keyboard 1, the calculation is performed by the control section 8, and the calculation result is displayed on the display section 2. Further, the result of this calculation is also stored in the work area 7a by the program 5.

Next, the operation of this device will be explained with reference to the flowchart shown in FIG.

This device normally operates in the data output mode, and when the calculator key on the keyboard 1 is pressed, the operating system shifts the operation to the calculator function program 5.

In the calculator function program 5, after completing a series of calculations,
The calculation result is stored in the work area 7a and the operation is completed. Next, when the operation mode shifts to the original human output control program 4, when the calculator data import key on the keyboard 1 is pressed, the control unit 8 reads the data stored in the work area 7a, and inputs it from the keyboard 1. The data will be treated as equivalent to the data provided.

That is, to explain the above-mentioned operations in blocks according to functions, as shown in FIG. 3, the key control block 31 determines the functions of the device, and also inputs data and arithmetic expressions. The arithmetic function block 32 calculates the input arithmetic expression, displays the result on the display section 2, and stores it in the work area 7a. Input/output control block 33
Then, the data from the key control block 31 and the data stored in the work area 7a are processed as human data. By providing means for associating the output results of the arithmetic function block 32 with the input/output control block 33 in this way, it is possible to facilitate the operator's manual data manipulation.

As explained above, the present invention stores the calculation results of a portable terminal device that functions as a calculator in a work area that can be accessed when it functions as an input/output device.
This has the effect of facilitating manual data manipulation by operators.
