Abstract

PURPOSE:To prevent a tuning device from having an error in channel selection caused by the vertical flaps of the front and rear ends of the rotary plate of a push-button tuner with double traverse plates to be stored during channel selection. CONSTITUTION:Two traverse plates Ca and Cb have holes with slanting edges 13a and 13b and when a push button 6 is pressed, two storage parts (pin) 2a and 2b of a frequency storage part piece 4 provided to the channel selection member A strike the slanting edges 13a and 13b to draw the traverse plate Ca to right (left) and the other traverse plate Cb to left (right). At this time, pivotal points between those two traverse plates and rotary plate 11 move up and down, and their fulcrum 10 has inclination to generate a play. For this purpose, a raised part 25 with a pressing part piece 22 is fitted to the substrate as shown in the figure and the circular hole edge 11' of the rotary plate 11 is inserted into the gap. Thus, the vertical flaps of the front and rear edges of the rotary plate are prevented.

３１ｂに対する衝合が解かれたとき消失する。However, the state in which the frequency storage piece (4) is suppressed is 9K.
When the push button (6) is pressed, the channel selection member A moves forward against a restoring spring (not shown), and one of the memory sections (21a is the corresponding inclined edge fi3) is moved forward.
a K abuts against each other, and due to this abutting action, one of the transversely moving plates Ca moves laterally to the left in the figure, and as a result, the other transversely moving plate O also moves laterally to the right. These two lateral movements llCa, C
For the relative movement of the channel selection member A and the sliding movement of the channel selection member A, a pair of memory sections (21, (2tl), as shown by the imaginary line in FIG. At the same time, their movement stops and the rotational part fi corresponds to the relative movement stroke of the two lateral movement plates C & M.
Tuning is performed by rotating υ and changing the variable inductance element, which is the same as in conventional push-button tuners. When abutting against the corresponding inclined edges α- and nib, respectively, the - movable part (one pivot part of 11 + 13. has its intermediate pivot part Q).
(The direction 0 force (arrow a) that pulls l forward is applied to the other pivot part C1'21b of moving part piece a1. (arrow b) acts, and due to this action and some backlash existing in the pivot joint, etc., the rotating part an tends to be agitated in the vertical direction with the intermediate pivot joint as a base point and tilt to some extent. That is, as shown in Fig. 3, when the rotating member αB is tilted from the state shown by the solid line to the state shown by the imaginary line, the pin also changes from the state shown by the solid line in the figure to the state shown by the imaginary line. K11jl as shown, this tlK
Therefore, the connecting piece (18') moves more or less in its longitudinal direction.The tilting action due to the tilting of the rotating piece aυ is performed by the inclined edges (13a, (1) of the memory part (2)a, +2To).
It disappears when the collision against 31b is resolved.
