1, 2, and 6 show that when the detection lever 12 is swung in the counterclockwise direction in FIG. The gear 33 is in mesh with the gear 43 on the spool 38 side, and is out of mesh with the gear 39 on the ribbon spool 37 side. In this state, the pulse motor 5 When a pulse signal for winding the ink ribbon is applied to the shaft 8, the shaft 8 is rotated by a predetermined amount in a predetermined direction (the direction indicated by the arrow in FIG. 1), and the rotation is caused by the timing belt 11, gear 6,
10, 24, shaft 27, gears 25, 34, 42, 4
3 and shaft 44, etc., to the ribbon spool 38, and the ink ribbon 46 from the ribbon spool 37 is wound onto the ribbon spool 38. This state will be explained later in detail with the switching lever 2.
2 is maintained by the biasing force of the spring 32 until it is switched. In this way, ribbon spool 3
8, the winding of the ink ribbon 46 progresses, and the ribbon 4 wound around the ink ribbon spool 37
When the eyelet 47 provided at the end thereof engages with the notch 19 of the detection lever 12, and the winding movement causes the detection lever 12 to swing in the direction of the arrow in FIG. 6, this swing causes conversion. The lever 22 swings in the direction of the arrow in FIG. 6 against the bias of the spring 32.
The gear 34 disengages from the gear 42, and
As a result of the gear 33 meshing with the gear 39 on the ribbon spool 37 side and switching, the rotation of the pulse motor 5 for winding up the ink ribbon 46 is controlled by the timing belt 11 gears 6, 10, 25, 33, 39.
and is transmitted to the ribbon spool 37 via the shaft 40 so that the ribbon spool 3
Eight ink ribbons 46 are wound up.
(FIG. 7 shows this state.) This state is maintained by the biasing force of the spring 32 until the switching lever 22 is switched.
