Claims

[Claims for Utility Model Registration] A switching drive gear 5 that is rotationally driven by the motor 6, a power switching gear 40 that is rotationally driven by the switching drive gear 5, and a drive cam that rotates together with the power switching gear 40. 43
an auxiliary lever 29 connected to the activation lever 26 and whose relative position with respect to the activation lever 26 is variable; and an auxiliary lever 29 driven by the solenoid 50 and connected to the power switching gear 40. a trigger lever 51 that changes the relative position of the auxiliary lever 29 with respect to the starting lever 26 while starting and stopping the auxiliary lever 29 while the starting lever 26 is driven by the power switching gear 40; Guide 3 that maintains the relative position at a constant position
3a, 33b, and a pair of reel stands 9a that support the tape reel.
A power switching lever 21 is provided to drive the idler 12 that selectively transmits power to the idler 9b, and the starting lever 26 and the auxiliary lever 29 have a combination shape depending on the relative positions of both levers. A switching mechanism for a tape player in which changing cam holes 34 and 35 are provided, and the power switching lever 21 is driven by the cam holes 34 and 35.
