Abstract

PURPOSE:To attain the immediate transfer of desired information and to de crease the waste time by sending selectively the character information, the operating information on a pointing device, etc. according to a transfer request given from a device at the receiver side. CONSTITUTION:A keyboard controller 2 always monitors a transfer command given from a host computer 4 and then transfers the corresponding information to the computer 4 in accordance with the transfer command for the character information and the operating information on the X or Y direction of a pointing device like a mouth, etc. Therefore only the information required by the computer 4 is transferred only when necessary. This wastes no time for transfer of information.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention particularly relates to a keyboard information transfer control method used in devices such as information processing devices.

[Conventional technology]

Conventionally, in information processing devices equipped with a pointing device (commonly known as a mouse) in addition to a keyboard with character and numeric keys, character information from the keyboard, operation information in the X and Y directions of the pointing device, and switches are provided. When transferring the on/off information to the information processing system on the host side, many devices add header information for synchronization to the beginning, and then sequentially transfer the above information.

[Problems to be Solved by the Invention] However, in the case where the character t# information etc. are transferred in a predetermined order as described above, for example, even when the pointing device is not being operated in any way, the pointing device is It is necessary to prepare a time to transfer the operation information, and the information processing device on the host side also has to wait for a long time until the transfer time for all information ends, which results in wasted time. There was a problem that the processing efficiency as a whole was poor.

Means for Solving Problems 2 Effects] The present invention selectively transfers information such as character information in response to a transfer request from a transfer destination device, thereby eliminating wasted time for transfer. , which aims to improve processing efficiency.

〔Example〕

The present invention will be explained below with reference to Examples. FIG. 1 is a block diagram showing one embodiment of the present invention, and the present invention is applied to a keyboard device 1. As shown in FIG. This keyboard device 1 is provided with character keys and numeric keys (not shown), and further includes a keyboard controller that detects a single operated key when operating these keys and generates character information or numeric information corresponding to the key. 2 is provided. This keyboard controller 2 has a pointing device 3.
Operation information in the X direction and Y direction and on/off information of the on/off switch are input in parallel, and information such as character keys or output method information of the pointing device 3 is input in parallel according to the transfer command from the host computer 4. The information is selectively transferred to the host computer 4.

FIG. 2 is a flowchart showing the transfer processing operation of the keyboard controller 2, in which the keyboard controller 2 constantly monitors transfer commands from the host computer 4 and the like (steps 10 to 13). When any transfer command is received, the information on the seed number corresponding to the transfer command at this time is selected and transferred to the host computer 4 (steps 14 to 17). For example, when receiving a command to transfer operation information in the X direction of the pointing device 3, the operation information in the X direction is selected and transferred to the host computer 4.

Therefore, according to such a gutter bottom, the host computer 4
Since only the information that is needed is transferred whenever it becomes necessary, there is no wasted time for transfer, and the overall processing efficiency can be improved.

Note that it goes without saying that the same effect can be obtained even if the keyboard device iiζ is limited to the keyboard and the pointing device.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, information such as character information is selectively transferred in response to a transfer request from the destination device S, etc. This has the advantageous effect that wasted time is eliminated, information needed by the destination can be transferred immediately, and overall information processing efficiency can be improved.
