Abstract
PURPOSE:To simplify a clutch mechanism, by directly coupling the clutch plate and a tuning shaft. CONSTITUTION:A kick arm 22 is not turned at the channel selection by a tuning knob. Thus, a tuning shaft 17 is depressed with a coil spring 21 and a friction member 19 at the tip is pressed with a projection 16 of a clutch plate 15. At the channel selection by a push button, when the push button is depressed, the kick arm 22 turns around a fulcrum 24. Then, an index 27 formed at the end of the kich arm 22 is lifted up from an arm 26 and a tongue 29 is also lifted up. Since a tuning shaft 17 is coupled with the tip of the tongue 29, the tuning shaft 17 moves along a taper 30 of the tongue 29. As a result, the tuning shaft 17 moves against the pressing force of the coil spring 21 and the pressing between the tip of the tuning shaft 17 and the clutch plate 15 is released.
