! ! In the middle of the process, Toshimoto, a member of the work, was restrained and
), Fltl @The tuning member in the holding state completely disables the tuning, and the operating member displays the position of the tuning mechanism during tuning, and furthermore, the tuning member in the forward holding state performs manual adjustment. 4 to preset in conjunction with the Yutaka mechanism! ? The push-button recycle device that has been developed has already been proposed in Japanese Patent Application No. 183982/1982.
ところで、上記した既発間の押釦式回訓器に。By the way, regarding the push-button recycler mentioned above.
選局動作中の雑音を消去する目的で、その選局動作に関

ィング操作機構を装備しようとすると、以下のような不
都合を有する。If a muting operation mechanism is installed to turn off the audio circuit of the radio receiver in connection with the tuning operation in order to eliminate noise during the tuning operation, the following disadvantages arise.

なされることがら困雌であるので、操作部材の肋陵動作
に関連して行う必要がある。That is, for its purpose, the operation of the switch for muting operation needs to be maintained at least until the tuning member is moved forward by the operating member and then held in the forward position. Operation of the switch 1. What should be done in connection with the operation of the channel selection member is difficult because it is difficult to select a channel when the channel selection member is in the forward motion state, so it is difficult to do anything related to the operation of the operating member. It is necessary to do so.

う不都合を有する。However, if the muting switch is operated in conjunction with an operating member, the operating member will be more immersed in the non-tuned state than in the non-tuned state, and will be in the next state. , the operation of the muting switch cannot be simply related to the operation member 1b, and the muting switch is actuated in conjunction with the operation member Fi'i], and then the tuning section $1) is moved forward. When configuring it so that it is tilted, the suppression stroke of the operating member must include the stroke necessary to operate the muting switch in addition to the stroke necessary to select the IY4 station member. This has the disadvantage that the aesthetic dimensions of the height tuner become large.

tを表示する。Therefore, when the 2nd push-down α21t is pressed against the restoring spring α9 from the non-tuned state shown in Fig. 2, the +4 operating rod (9) bends and the locking piece <1)1 comes into contact with the inclined line of the locking part, and the restraint piece (7) temporarily moves sideways against the spring (at the time of this movement, other operations that are locked to the locking part) The locking piece (1) 1 of the member t131 comes off). Next, as the operating rod (9) moves forward, the tongue αα moves to the operating member (6) opposite to it, as shown in FIG.
Since it comes into contact with the protruding piece (41'), the channel selection member (8; moves forward together with the operating member a3.) With this forward movement, the locking piece 6 comes into contact with the inclined edge of the locking part 2, and is locked. Piece Q4 temporarily moves laterally against its spring 1271 (at the time of this @ excitation, the protruding piece (jllg of the other tuning member +81 that is locked on the locking part c!■) comes off)0 Then, as shown in Fig. 5, after the channel selection member (81) has moved forward sufficiently, press the push button σ force to t〈, and then press the button σ force to the end (with the channel selection member 81 moved slightly backward). -, L LLL l'1C

At the same time, the gear (7) meshes with the transmission gear ta of the transmission mechanism C. On the other hand, the operation member (91) is further retreated by its belly spring a9, but in the middle of this movement, as shown in the off-line diagram, the locking piece 01: locks into the locking part (2) of the restraint part. Then, its retreat is restrained, and the button push button becomes more immersed than the position in the non-tuning state shown by the imaginary line in the same figure, and as a result, the position of the tuning system is displayed. .
