<p>PURPOSE:To enhance the controllability and at the same time realize a small-sized and thin-gage structure for a tape player, by locking a control member at the position of reproduction with use of an electromagnetic plunger. CONSTITUTION:A working member 7 interlocking a rotary cam 14 which is driven by a rotary motor mechanism is used to actuate a control member 3 that gives a forward/backward movement to a reproduction relating mechanism of a head and a pinch roller or an idler. At the same time, the member 7 carries out both the forward/backward operation of the reproduction relating mechanism and the switching operation of a channel in a single mechanism through an operation of the switching cam 14 which is used for switching of channels.</p> |
