Abstract

PURPOSE:To obtain an electronic computer requiring no large scale by putting a system program and a real processing program in one body into an IC card and inserting this IC card into the computer main body for execution of various arithmetic operations. CONSTITUTION:An IC card 8 contains a system program and a real processing program at a ROM part 8a. Then a connection part 8b of the card 8 is connected to an interface part 7 of an electronic computer main body. In such a constitution, the card 8 is put into the interface 7 and a power supply is applied. Thus the prescribed arithmetic operations are carried out in response to the program contents of the card 8. Therefore a ROM pack, etc., which are inconvenient in handling can be omitted and the thickness and the size of the card 8 are reduced. As a result, the operability is extremely improved together with the improvement of the space efficiency with the electronic computer.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic computer that processes input signals based on a predetermined program.

[Prior Art] FIG. 3 shows an example of a conventional electronic computer. The central processing unit (1) that controls the overall arithmetic processing functions of the computer main body includes a ROM (2) that stores system programs related to processing operations specific to the computer, and a RAM (3) that temporarily stores calculation results of input data. is connected and a signal is supplied by the user from an input section (5) such as a keyboard, the central processing section (1) displays the processing result on the display section (4).

A ROM pack (6), which is a cartridge containing an actual processing program for causing the computer to execute a predetermined function, is connected to the central processing unit (1) via an interface (7) of the computer main body. There is.

Next, the operation will be explained. When the power is first turned on, the ROM
(2) checks whether a ROM pack is inserted. If No, of course the main unit will not work, but YE
If it is S, it performs arithmetic processing based on the program in the ROM pack (6).

For example, recording data in the RAM (3), arithmetic processing based on input signals, receiving data from the input section (5),
This includes displaying data on the display section (6), etc.

[Problems to be Solved by the Invention] However, since the above-mentioned conventional device uses a ROM pack as a command program for executing various functions of the computer body, the problem is that as the amount of information increases, the device becomes large and inconvenient to handle. was there.

In other words, since a ROM pack is constructed by mounting a ROM on a substrate, an increase in the amount of information directly results in an increase in the size and thickness of this substrate.
This in turn led to an increase in the size of the computer itself, resulting in a decrease in operability and space efficiency.

Purpose of the Invention The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide an electronic computer in which a program for actual processing of an electronic computer can be configured in a small and simple manner, without causing an increase in the size of the device. It's about doing.

[Means for Solving the Problems] The computer according to the present invention integrates a system program related to the operating functions of the computer itself and an actual processing program for executing various functions of the computer in an ultra-small and thin IC card. It is constructed so that various calculation operations can be performed by inserting a card into the main body.

[Function] In the present invention, the functional operations specific to the computer and the actual processing operations selected by the user are carried out by connecting an ultra-small and thin IC card containing both programs to the connection part of the computer. This is accomplished by inserting.

[Example] Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 1 is a block diagram showing the overall configuration of an electronic computer according to the present invention. In the figure, the same components as those in the conventional device are given the same numbers, and their explanations will be omitted.

A feature of the present invention is that a small and thin IC card is used for both the system program related to the specific operations of the computer and the various arithmetic processing execution programs.

This eliminates the need for ROM packs that are inconvenient to handle, greatly improving operability and increasing space efficiency.

Figure 2 schematically shows the IC card according to the present invention.The ROM part (8) in the figure contains both a system program and an actual processing program. The connecting portion (8a) is connected to the interface portion (7) of the computer main body.

Therefore, connect the IC card (8) to the main unit's interface (
When the IC card (8) is inserted into the IC card (8) and the power is turned on, predetermined arithmetic processing will be performed according to the program contents in the IC card (8). The processing contents here include word processing,
Examples include telephone directories, address books, schedulers, etc.

In the above embodiment, the IC card (8) is configured to contain both the system program and the actual processing program, but the system program can also be connected to the main body.

It is also possible to arrange a RAM in the IC card (8) and record data in the card for each function.

[Effects of the Invention] As explained above, according to the present invention, since the program for executing each function is built into the IC card, the card can be made smaller and thinner, and its operability can be improved. becomes possible.
