Abstract

PURPOSE:To provide a spring with all the functions required for connecting a payout bobbin and a take-up bobbin and reduce the number of component parts, by providing a composite spring formed of a spring material, having one end fixed and the other end being a free end through which an ink ribbon is passed, and supporting a payout bobbin between the one end and the other end. CONSTITUTION:With a take-up gear 9 rotated in the direction of arrow (a), a back tension is exerted on the ink ribbon 1 against a frictional force exerted on the payout bobbin 2, and when the back tension becomes equal to the frictional force, the ribbon 1 is rotated in the direction of arrow (b), and is taken up by a predetermined pitch. At this time, the take-up bobbin 10 is constantly energized by the composite spring 14 in the direction of the take-up gear 9, whereby the bobbin 10 is prevented from idly rotating. As the take-up of the ink ribbon proceeds, the diameter of the bobbin 10 increases, so that the bobbin 10 is displaced in the direction of arrow (c) along a take-up bobbin guide 12. Therefore, the payout bobbin 2 is displaced in the direction of arrow (d) through flexure of the spring 14 with a boss 16 as a center.

By rotating the take-up gear 9 in direction a, pack tension is applied to the ink ribbon 1 against the frictional force applied to the feed bobbin 2, and when the frictional force becomes equal to the pack tension, the ink ribbon 1 It rotates in the opposite direction and is wound up by a predetermined pitch. At this time, the winding bobbin 10 is always urged toward the winding gear 9 by the composite spring 14 to prevent the winding bobbin 10 from idling. As the ink ribbon winding progresses, the winding bobbin 10 becomes larger in diameter and is displaced in the direction C along the winding bobbin guide 12. Therefore, the feed bobbin 2 is displaced in the direction d as the composite spring 14 bends around the boss 16.
