Abstract

PURPOSE:To contrive reductions in size and weight of a carriage and further in cost, by providing a switching means by which a driving force generated from a drive source is transmitted to either a type-selecting means or a ribbon take-up means. CONSTITUTION:When a pulse motor 2 is rotated counterclockwise, a one-way clutch 6 transmits the rotation of a shaft 2' to a pinion 4, whereas when the motor 2 is rotated clockwise, the transmission of the rotation from the shaft 2' to the pinion 4 is cut off. With the motor 2 roasted clockwise, a type wheel 1 is also driven to rotate counterclockwise through gears 3, 4, whereby a type corresponding to character data is positioned in front of a hammer 12. With the motor 2 rotated counterclockwise, a rack 5 engaged with the pinion 4 is moved in the direction of an arrow B. In this case, a gear 9 is rotated in the direction of an arrow C through engagement with a ratchet 8 provided on the rack 5, whereby a ribbon take-up shaft 9' inserted in the gear 9 is rotated in the direction of the arrow C, and a ribbon 11 is taken up by a ribbon take-up bobbin 10.
