PURPOSE:To simplify the pointer mechanism, by fitting a rear end and moving plate of a pointer plate freely turnable to a shaft and linking a pointer plate turning chip of the moving plate with the pointer plate. CONSTITUTION:A pointer plate 20 has a pointer 21 at the tip, and the rear end is fitted freely turnably with a shaft projected on the frame of a push button tuner. An L-shaped moving plate 23 is fitted freely turnably at the lower stage of the pointer plate 20 of the shaft 22, a turning piece 23A of the plate 23 is linked with the pointer plate 20 with a pin 24 and a pin 25 provided with an engaging piece 23B is inserted in a coupling hole 27 of a core slide 26. The core slide 26 is moved back and forth with the operation of a tuning knob or a depressing operation of a push button and the moving plate 23 turns around the shaft 22. The pointer plate 20 also turns with the turning of the moving plate 23 and the pointer 21 displays the amount of movement of the core slide 26. |
