2.3 Power Transmission Mechanism
The equipment has a single drive motor whose power transmission route can be switched by
the planetary gear train and the solenoid. This switching allows the equipment to function in
four operation modes (recording, scanning, copying, and cutter driving modes).
2.3.1 Structure of the gear train
The gear train consists of two groups of gears: one group on the drive unit and the other on
the scanner frame ASSY. Mounting the drive unit onto the scanner frame ASSY makes
those two groups of gears engage with each other so that the rotation torque of the motor on
the drive unit is transmitted to the separation roller, white pressure roller, and platen.
Shown below are a group of gears, the motor and solenoid on the drive unit. The cutter gear
(Q) is integrated in the cutter flange (R) whose boss is placed in the hole provided in the
cutter’s upper blade.
