JPH07104904A - Keyboard card - Google Patents

Abstract

PURPOSE:To mount keyboards provided with plural and different key arrangements by forming the keyboard in the shape of a card concerning an information processor with integrated keyboard. CONSTITUTION:The keyboard card is composed of a system device 1 for the information processor equipped with a card socket 1 and card-shaped keyboards 3, 4 and 5 equipped with a common interface. Therefore, a personal computer provided with versatility can be easily extended to a dedicated terminal provided with any special key arrangement and can be compatibly utilized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card type keyboard in a keyboard integrated personal computer.

[0002]

2. Description of the Related Art Cards specified by JEIDA or PCMCIA. However, there is no keyboard.

[0003]

Personal computers have become widespread, and in recent years, they are often used for various dedicated terminals. The dedicated terminal has a special keyboard layout for ease of use in the field. However, in the conventional keyboard-integrated personal computer, if the arrangement is changed, its versatility is lost, and it is necessary to develop replacement driver software for system operation or the operator to read the keyboard input. . Further, various application software operations as a personal computer cannot be performed, and the dedicated terminal and the personal computer cannot be used in combination.

[0004]

According to the present invention, the host interface of the integrated keyboard is a card type, and the keyboard itself is designed to have a single card structure so that it can be easily attached / detached. Personal computers can be used on both.

[0005]

The system unit has a card-type socket as a keyboard mounting interface, and the keyboard is
It is a keyboard-integrated information processing device that itself is configured as a card and that allows multiple keyboards to be interchangeably mounted by sharing a common interface architecture. The connected keyboard and system unit in the form of a card facilitates attachment and detachment using the keyboard as a card.

EXAMPLES Examples of the present invention will be described below.

An embodiment of the present invention will be described with reference to FIG. The system device 1 of the keyboard-integrated personal computer includes a card socket 2 as a built-in keyboard interface. Further, a guide structure 7 for mounting a keyboard card is provided. The keyboards that can be mounted include a general-purpose keyboard 3 and keyboards 4 and 5 having a special keyboard layout. Each keyboard has a card-shaped protrusion 6 as a connection interface with the system unit 1.

The keyboard itself, including the protrusion 6, is mounted while sliding the guide structure of the system unit 1 like a card, and the protrusion 6 is inserted into the card socket. As shown in FIG. 2, a keyboard matrix 8 and a keyboard LED 9 are provided in the keyboards 3, 4 and 5, and lines for controlling these are received from the system unit through the card interfaces 2 and 6. As a control line, a key matrix scan line 10, an LED control line 11, and a type classification signal 12 for discriminating a keyboard type are basically used. System unit 1 by type type signal
The internal keyboard controller 13 switches the matrix table and issues a key scan code according to the attached keyboard. Also, in the case of a keyboard that does not have a code table, the key scan controller 14 is installed in the keyboard, and the system unit 1
Then, the scan code information is passed through the serial communication line 15. All of these control signals are controlled by the keyboard controller 13 in the system unit.

In the present embodiment, the card interface signal is specified by the signal specific to the keyboard card, but it can be configured as one I / O device in accordance with a versatile card standard.

[0010]

According to the present invention, a general-purpose keyboard-integrated personal computer can be used for both a dedicated terminal and a general-purpose application, and system construction is facilitated. It can be widely used for various business purposes as a personal computer while maintaining operation compatibility. Also, the system provider can easily deploy the personal computer as an engine of a dedicated system.
