Abstract

An electric field-induced cordless mouse device with convenient operation is disclosed. The mouse device includes a cordless mouse, a mousepad and a housing. The mouse has a double-head trigger circuit connected to an output of a conventional interior circuit therein for converting a square-wave signal into a pulse signal. The interior circuit and the double-head trigger circuit are connected to a common power supply, and in a preferred embodiment, to a rechargeable battery. A connection point and a plurality of pulse transmitting electrodes are formed on an undersurface of the mouse. The electrodes are connected to the double-head trigger circuit for outputting signals. The mousepad is formed of a flexible pad, a metal sheet and an insulating pad. The metal sheet is made of a metal foil and connected to an RS-232 interface circuit in a computer via a demodulating circuit provided for converting a pulse signal to a square-wave signal. The housing is connected to the RS-232 interface circuit via a two-way signaling cord. The housing has a mouse accommodating portion, a charging circuit therein for charging the battery of the mouse and a plurality of conducting strips contacting the connection point of the mouse for detecting the setup program.

Claims
