Title:
A CIRCUIT DEVICE FOR PAPER SHEDDER
Document Type and Number:
WIPO Patent Application WO/2008/151478
Kind Code:
A1
Abstract:
A circuit device for paper shredder includes a motor (1) for driving a shredder mechanism, and a controller, in which the controller comprises a microcontroller (2), a switch circuit (4) for controlling power for the motor, a touch detection circuit (3). The touch detection circuit includes a touch sense strip provided at a paper feed entry and a touch sense module connected with the touch sense strip. The output of the touch detection circuit is connected to the touch signal input of the microcontroller. When a human body or an animal touches the touch sense strip, the sensed ground signal is sent to the touch signal input of the microcontroller via the touch detection circuit, and the microcontroller controls the switch circuit to cut off power, thus to ensure the shredder to stop, thereby the human body or animal is prevented from damage for misoperation.
