One operating member (11 and two channel selection members housing & and a&'
When trying to provide a push-button tuner with many tuning functions by equipping a single support frame A3 with a large number of tuning mechanisms each having one set of In particular, when selecting a channel by forward movement of the channel selection member near the longitudinal end of the slide plate (c), the channel selection piece 124
There is a risk that the slide plate (c) will tilt to some extent on the plane due to the force of collision with 1 to 241', which will only impair the smooth sliding of the slide plate 69 and reduce channel selection errors. This disadvantage largely occurs when the width of the front edge of the support frame t131 is short for downsizing, and therefore the distance between the front and rear support points of the slide plate ch51 with respect to the support rod is short.

る。As described above, according to Book A, the horizontal dimension of the unit sliding plate is shortened, so even if the tuning pieces of the tuning member collide at both end positions of the sliding plate, the collision force There is no fear that the slide plate will tilt on the horizontal plane, the slide plate can slide smoothly, and the occurrence of station errors can be prevented, thereby providing a push-button tuner with high station accuracy.

素子を連結したことをｔｒｆ徴とする押釦式同調器。The operating member includes an operating member having a main drive gear, and a channel selection member having a channel selection piece mounted on a threaded portion so as to be movable back and forth, and a driven gear meshing with the main drive gear. While moving forward and maintaining the forward moving state, tuning is performed by abutment between the tuning piece of the tuning member in the forward moving state and a slide plate that interlocks with the variable tuning element, and the main gear and the driven gear are moved forward. In a push-button tuner configured to perform a reset by meshing with a gear, the slide plate is divided into a plurality of parts, each divided slide plate is supported with respect to a support frame so as to be movable back and forth, and each slide A push-button tuner whose trf characteristic is that p'' variable tuning elements are connected in correspondence with the plates.
