DRIVING FORCE TRANSMISSION MECHANISM IN IMAGE FORMATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a driving force transmission mechanism in an image formation device which prevents the trouble by a simple configuration that a transfer roller cannot be driven by a correct timing due to a slip caused by the invasion of grease in a coupling part (friction face) between a rotor and an armature of a clutch used in the image formation device so that a recording paper can be transferred only when a transfer command comes while the grease is generally used in the driving force transmission mechanism to smoothly transmit the clutch driving force and to make the sound quiet. SOLUTION: A motor is set at one face of a drive plate constituted of one sheet of a plate material. A mechanism for transmitting the driving force to a paper feeding/transfer system in the image formation device, and a means for transmitting and cutting the driving force to a roller of the paper feeding/transfer system are set at the other face. A gear at the driving force transmission mechanism for transmitting the driving force and transmitting the driving force to the cutting means is made a two-stage gear. COPYRIGHT: (C)2005,JPO&NCIPI
