THEORY OF OPERATION
Fig. 2-17 Print Head Carrying Mechanism
4-3. Ink Ribbon Feed Mechanism
The ink ribbon feed mechanism is linked to the print head carrying mechanism described previously so that the ink ribbon
is wound up automatically while the carriage moves left or right.
The ribbon feed mechanism is driven by torque from the carriage motor, and carriage movement allows the idler gear to
rotate.
This rotation is conveyed sequentially to the gears that work to wind the ribbon. The carriage is equipped with a clutch
lever so that the direction of cassette gear rotation remains constant regardless of the direction of the idler gear rotation.
