Document Type and Number:
WIPO Patent Application WO/2010/121545
Kind Code:
A1
Abstract:
An electric paper shredder is disclosed, which comprises a SCM (Single Chip Micyoco) (23), a positive rotation drive circuit (24), a reverse rotation drive circuit (25), a motor (18), a sensor (13) and a lifting controller (12). The SCM is connected with the positive rotation drive circuit and the reverse rotation drive circuit which are both connected with the motor. The lifting controller is arranged at the bottom of a press board (14), and the sensor is arranged at a paper feeding port of the press board and connected with the SCM. The press board of this paper shredder is far away from a paper feeding roller when there is no paper to be shredded, and fixed by the lifting controller. The sensor sends a signal to the SCM when there is paper to be shredded, a control signal is sent by the SCM to the lifting controller according to a set instruction. The press board is released by the lifting controller, and the paper to be shredded is pushed toward the paper feeding roller under the elastic force of a spring (17) arranged at the bottom of the press board. Paper can be fed conveniently in the paper shredder, thus the shredding operation can be simplified and shredding efficiency is improved.
