Abstract

PURPOSE:To utilize a card to display a key symbol and to increase the range of utilization of the card by providing a transparent sheet key which have no key symbol display over the card loading surface of an electronic instrument body and displaying the plural key symbols corresponding to incorporated software on the card surface. CONSTITUTION:The main body B of the electronic instrument is provided with a display part D, a common key K1, and the transparent sheet key K2 and an external input/output terminal E is at one corner. This main body B is held in a pocketbook case G, a card holder H is provided to the case G, and an application card A is inserted into the holder H and held therein. Then, a key symbol and the explanation corresponding to the incorporated software are printed on the surface of the card A. Then, the card A when used is inserted into the card loading part provided under the sheet keys K2 and a symbol on the card A is pressed through the sheet key K2 to generate a specific key input, increasing the utilization range of the card A.

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an electronic device main body having a key input section, a calculation section, a display section, etc., and a software built-in card (ROM or RAM or ROM) that is detachably attached to the main body. , cards containing both RAM and RAM) and architectures (e.g., pocket O-computers, personal computers, programmable measuring instruments, etc.).

<Prior Art> In conventional personal computers, a key that changes depending on the software is prepared as a definable 0 key, and a key 0 symbol is written near this key using the software. Therefore, it was necessary to rewrite this symbol every time the software was switched.

<Object of the invention> The present invention has been made with the aim of eliminating the above-mentioned inconvenience.0 <Configuration of the invention> The configuration of the electronic device of the present invention that achieves the above-mentioned object is as follows. It is.

That is, the electronic device of the present invention includes a key human power section, a calculation section,
In a device consisting of a device body having a display section, etc., and a software built-in card that is detachably attached to the device body,
A transparent sheet key without a key 0 symbol is provided above the card mounting portion of the main body, and
The present invention is characterized in that a plurality of keys and symbols corresponding to the card (built-in software) are displayed on the surface of the card. It should be noted that if explanations corresponding to the built-in software are also displayed on the card surface, it will be easier to use.

<Example> Hereinafter, the present invention will be described in detail based on examples. FIG. 1 is an external perspective view of one embodiment of the present invention.

On the main body B, there is a 1 on the display D1 common key and a transparent sheet 0.
2 is provided on the key. Note that E is an external input/output terminal. The main body B is held in a notebook case G. This notebook case G has a card.

A holder H is provided, into which an application card (software built-in card) A is inserted and held. On the surface of this card A, symbols of keys necessary for the built-in software and explanations corresponding to the built-in software are printed. When in use, insert the card A into the card mounting section provided below the transparent sheet O key 2.

FIG. 2 is a sectional view showing the relationship between transparent sheet key 2 and card A when the card is inserted.

Transparent sheet O key 2 is two transparent films T1, T
It has a structure in which a transparent electrode is formed on 2 and a separator S is provided between the two facing each other, and an application 0 card A is inserted under this.

A connection terminal is provided on the back surface of the card A, and when this connection terminal comes into contact with a contact connector J on the main body B side, an electrical connection between the circuit within the card and the circuit within the main body is achieved.

F indicates the user's finger, and the user follows the key 0 symbol printed on the card surface and presses the transparent sheet 0 key above it. Thereby, a predetermined key human effort is performed.

FIG. 3 is a circuit block diagram of this embodiment.

The calculation mounted CPU is connected to the display section D1, the external input/output terminal E1, the common key 1, and the transparent sheet
2 is connected to the key. Furthermore, read-only memo with built-in control program! Random access memory RAMI used for JROMI and data storage, etc.
is connected.

Inside the broken line is Card A, read 0 only 0 memory ROM 2 containing application software, or random as needed. Access memory RAM2 etc. are built-in.

As explained in detail above, according to the electronic device of the present invention, the key symbols suitable for the software are displayed at the same time as the card with the built-in software is inserted, so there is no need to write them on a sheet. Also, since there is no need to operate the table from the beginning, it is possible to prevent operational errors. Furthermore, the card shape is not simply used as a case for ROM, etc., but is also used to display keys and symbols, making the card shape more effective.
