ABSTRACT:
A thin ribbon cassette (16) is set on a tape winding device and its vertical-direction position is fixed by a position restricting member (18) provided on a back of a cover for an apparatus body. When the ribbon cassette (16) is thin in correspondence to a narrow width of an ink ribbon (15), a quantity of lowering of a ribbon winding top (5) engaged with a reel (16-1) of the cassette (16) is small. The biasing force of a clutch spring (7) which is compressed depending on the quantity of lowering of the ribbon winding top (5) is small, the force of a winding drive gear (6) which presses a clutch plate (4-1) through a felt member (12) is small, the frictional force of the felt member (12) is small, and the torque of the rotational shaft (4) is small. This torque is just suitable for winding a long and narrow ink ribbon having a corresponding small tensile strength. When a thicker ink ribbon cassette (22) is set on the apparatus body, the quantity of lowering of the ribbon winding top (5) is large, and the biasing force of the clutch spring (7) is correspondingly large, so that the torque of the rotational shaft (4) is large in correspondence to a long wide and ink ribbon (21).
