Power transmission switching mechanism for office machine

Abstract

A power transmission switching mechanism for office machine. The power transmission switching mechanism has simple structure and enables the office machine to commonly use a motor to execute scanning and printing works. The power transmission switching mechanism includes a rotary shaft, a drive gear mounted on the rotary shaft, an actuator reciprocally movable on the rotary shaft and a driving gear for transmitting power of a motor to the drive gear. The drive gear has an spline. The actuator can be selectively moved forward or backward to make the spline disengaged from a first gear mounted on the rotary shaft or engaged with the first gear. When the spline is disengaged from the first gear, the power of the motor is transmitted to a scanning module. When the spline is engaged with the first gear, the power of the motor is transmitted to the rotary shaft for printing work.
