Power transmission for four operation modes
Depending upon the clutch solenoid ON/OFF state and the motor rotation direction, the plan-
etary gear train switches the power transmission route for the four operation modes.

[ 1 ] Recording mode (Solenoid: OFF, Motor rotation: Forward)
In the recording mode, the control system deactivates the clutch solenoid (see the above fig-
ure, Solenoid: OFF). Therefore, when the motor rotates in the forward direction, the clutch
lever turns clockwise with the spring and its cutout

becomes engaged with the stopper of
arm A. Once arm A is locked, the planet gear 20A (C2) will not be engaged with any other
gear but simply idle.
The motor rotation turns the sun gear 18/73 (B) counterclockwise so that the planet gear 20B
(C1) transmits the rotation to the platen gear (E) via the gear D.
