DESCRIPTION:
BRIEF SUMMARY
This application is a 371 of PCT/JP94/00667 filed Apr. 21, 1994.
TECHNICAL FIELD
This invention relates to a man machine controller (MMC) unit for controlling a man-machine communication, and more particularly to an MMC unit to be connected to a computer numerical control apparatus, robot control apparatus, and the like.
BACKGROUND ART
In order to control a computer numerical control apparatus, robot control apparatus and the like, a man machine controller (MMC) unit becomes necessary for controlling a man-machine communication. For example, an MMC unit connected to a computer numerical control apparatus is allowed to implement an animated simulation operation, interactive program input operation, etc.
A control apparatus or an MMC unit, available for displaying images during such operations, is heretofore provided with display control means therein. The display control means has a processor by itself, wherein an image control signal from a processor of the control apparatus is converted to an image signal, and a resultant image is displayed on a display unit such as a cathode ray tube (CRT), a liquid crystal display (LCD), and the like. The control apparatus also contains transfer control means for transferring input data through operator keys.
When the display control means and the transfer control means are built into a control apparatus, however, the board on which the display control circuit is mounted must be replaced in its entirety when upgrading and changing of the display functions and operational functions are required, whereby cost efficiency and working efficiency are lowered.
DISCLOSURE OF THE INVENTION
In view of the above problem, it is an object of the present invention to provide an MMC unit wherein the display functions and operational functions are allowed to be easily upgraded, changed, and so on.
To achieve the above object, there is provided in accordance with the present invention an MMC unit for controlling a man-machine communication, comprising a display unit, data input means, a personal computer function card which contains a processor, display control means for controlling a screen display on the display unit in accordance with display data and display command signals from a main control apparatus, and data transfer means for transferring the input data supplied from the data input means and the data processed by the processor to the main control apparatus, and a socket to which the personal computer function card is detachably connected.
Images can be displayed on the display unit by connecting both the display unit for displaying images and the data input means, via respective connectors, to the personal computer function card which contains a processor, display control means for controlling a screen display on the display unit in accordance with display command signals from a main control apparatus, and data transfer means. As the personal computer function card is detachably connected to the socket, the personal computer function card can be replaced as required.
