Abstract

PURPOSE:To perform perfect rewinding operation by stopping the reversing of an idle cam temporarily in rewinding. CONSTITUTION:In rewinding, reverse rotation from a sprocket is transmitted to a counter drum 2 via a counter driving gear 1 and the drum 2 rotates counterclockwise. Consequently, an idle cam 3 reverses counterclockwise by the force of a spring 4. In this state, rewinding advances and the tip 5a of a switch 5 hits the flank 3c of the cam 3 to stop the reversing of the cam 3, and the drum 2 continues to reverse to complete the rewinding operation.
