2-1. Operation of Each Mechanism
2-11 CLP-621 & CLP-631
Reel Drive Mechanism:
Though the ribbon holders are directly installed in the reels, ribbon is connected to the reels via the
spring mechanism of the ribbon holders. This means that ribbon is taken up via the spring
mechanism when the Ribbon Motor F/R turns.
On the take-up side, the Ribbon Motor F turns in the clockwise direction viewing from the right side
of the printer, the Ribbon Gear 5F (take-up reel) turns in the counterclockwise direction via the
Ribbon Gears 1, 2, 3 and 4, and ribbon is taken up.
On the supply side, the rotational direction of the Ribbon Motor R differs depending on the ribbon
winding type to be used. In the case of the outside-wound ribbon as shown in the following figure,
the Ribbon Motor R turns in the counterclockwise direction, the Ribbon Gear 5R (supply reel) turns
in the clockwise direction via the Ribbon Gears 1, 2, 3 and 4, and ribbon is supplied.
