Abstract

PURPOSE:To attain the operation from an optionally remote location and to save the signal cable by providing a radio wave transmission section modulating a key entry signal into a frequency corresponding to a designated key from a key detection control section and sending the resulting signal as a radio wave. CONSTITUTION:In the depression of a key part 11 on a keyboard 15, a signal corresponding to a specific depressed key is fed to a key detection control section 12, where the signal is converted into a corresponding code. A radio wave transmission section 13 applies modulation by using a frequency in matching with the code signal and sends the result to an information processing unit 14. The information processing unit 14 demodulates the received signal into the original signal to recognize which key of the key pad is to be depressed.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明はキーボード装置に関し、特に信号ケーブルを使
用しないワイヤレスのキーボード装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyboard device, and more particularly to a wireless keyboard device that does not use a signal cable.

〔従来の技術〕[Conventional technology]

従来、この種のキーボード装置は、情報処理装置の本体

とができる。FIG. 1 shows an embodiment of the invention. In FIG. 1, in this embodiment, when a key portion 11 on a keyboard 15 is pressed and operated, a signal corresponding to the specific key pressed is sent to a key detection control portion 12. When the key detection control section 12 detects this, it converts it into a corresponding code and sends this code signal to the radio wave transmission section 13. The wave transmitter 13 modulates the code signal with a frequency matching the code signal, and then transmits it to the information processing device 14. The information processing bag 214 can determine which key in the key section has been pressed by demodulating the received signal.
