4-3. Ink ribbon feed mechanism
The ink ribbon feed mechanism is linked to the print head carrying mechanism so the ink ribbon always winds
automatically in the same direction while the carriage moves left and right.
The movement of the carriage along the serrated edge of the rear angle of the printer mechanism drives the idler gear. The
rotation of the idler gear is conveyed sequentially to the gears that work and wind the ribbon. The carriage has a clutch
lever that keeps the direction of the cassette gear rotation constant, regardless of the direction of the idler gear rotation
as the carriage moves left and right.
