リボン巻取装置。[Scope of Claim for Utility Model Registration] A ribbon cassette that is detachably attached to the main body of a printing machine, and a ribbon cassette that engages with a ribbon winding rotating body of the ribbon cassette at a predetermined meshing position to wind the ribbon. A ribbon winding device for a printing machine including a winding shaft and a drive motor that supplies torque for winding the ribbon to the winding shaft via a speed reduction mechanism connected to the winding shaft, a driven shaft connected to the speed reduction mechanism and rotatable about the axis of the winding shaft; and one engagement shaft rotatably and axially movably mounted on the driven shaft and connected to the winding shaft. a mating member, a second engaging member facing the one engaging member and mounted on the driven shaft so as to be movable only in the axial direction, and urging the other engaging member toward the one engaging member. and a biasing spring that engages between the one and the other engaging members to connect the two engaging members when torque is supplied from the drive motor to the winding shaft, and the ribbon winding rotating body 1. A ribbon winding device for a printing machine, characterized in that a ratchet mechanism is provided for separating both engaging members by releasing the engaged state while resisting the elastic force of an urging spring when torque is supplied.
