Recording mode (Solenoid: OFF, Motor rotation: Forward)
In the recording mode, the control electronics deactivates the solenoid. When the motor rotates in
the forward direction, the clutch lever turns counterclockwise with the compression spring so that its
cutout
becomes engaged with the stopper of arm A. Once arm A is locked, planet gear 34A
("J") will not be engaged with any other gear but simply idle.
The motor's rotational torque turns sun gear 24/90 ("B") counterclockwise so that planet gear 34B
("C") transmits the torque via sun gear 65/60 ("K") and other gears to the platen gear ("Y") and the
paper ejection roller gear ("R").
If gear 39/62 ("V") of the friction torque transmission ASSY rotates, gear 20 ("z") on the inner side of
the drive unit also rotates so as to drive the ribbon drive gear ("w") that rotates the ribbon take-up
gear ("a") on the ribbon cartridge, as shown on the next page.
Arm A Locked by Cutout
of Clutch Lever
Active Gears on the Outer Side of the Drive Unit and Left Side of the Platen Frame
