Abstract

PURPOSE:To smooth the manual turning operation of manual tuning mechanism at preset operation by receiving a meshing collor meshing with a turning system of the manual tuning mechanism by a reception piece fixing an elastic piece pressed elastically forward to the support frame and using the elastic force exerted to a channel selection member with a restoring spring only. CONSTITUTION:A transmission mechanism D is provided with a crown gear 34 meshed and pressed into contact with a pinion gear 19 by an elastic piece 33 at all times and consists of a transmission member 36 having an engagement 35 and a sleeve fitted freely turnably to a support piece 21 and a transmission collor 40 energized elastically by a spring 38 at all times and projected with an engaging projection 39 engaged with the engaging section 35. Further, the support frame bottom plate 13 is provided with a lock piece 44 freely laterally and energized elastically at all times by a spring 43 and a lock section 45 is provided correspondingly to each channel member 29 at the tail ridge. Thus, an elastic pressure of the elastic piece meshing and pressing in contact with the rotary shaft 20 of the manual tuning mechanism B is not exerted to the channel selection member 29.

に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present application relates to a push-button tuner that is particularly useful for in-vehicle radio receivers.

〔従来技術とその問題点〕[Prior art and its problems]

押釦の押圧操作によって前動した選局部材が前動状態に
保持された状態で選局が達成されると共に、この状態で
選局部材が手動同調機構の回転系と噛合して、手動同調

−１６７５１５号公報において公知である。Tuning is achieved with the tuning member moved forward by the pressing operation of the push button held in the forward moving state, and in this state, the tuning member engages with the rotation system of the manual tuning mechanism, and the manual tuning mechanism A push-button tuner in which precession can be performed by rotating the button is disclosed, for example, in Japanese Patent Application Laid-open Nos. 53-36i01 to 1983-60.
It is publicly known in the publication No.-167515.

ところで、上記したいづれの構成においても、前動状態
の保持された選局部材の噛合駒を、手動同調機構の回転
系に正しく噛合させるために、該噛合駒を強い弾性片に
より圧接する必要がある。Incidentally, in any of the above-mentioned configurations, in order to properly mesh the engaging piece of the tuning member held in the forward moving state with the rotating system of the manual tuning mechanism, it is necessary to press the engaging piece with a strong elastic piece. be.

そのため、その強い弾圧力が、選局部材の前動保持状態

抵抗として作用し、従ってプリセッＩ−操作時における
手動同調機構の手動回転操作が重くなると共に、微細調
整が行い難くなるなどの欠陥があった。Therefore, when the tuning member is in the state of forward movement and holding, the strong elastic force is applied in the axial direction of the tuning member along with the elastic force of the restoring spring, which creates a large rotational resistance between the tuning member and the support frame. Therefore, there were defects in that the manual rotation operation of the manual tuning mechanism during the preset I-operation became difficult and fine adjustment became difficult to perform.

〔発明の目的、実施例及び作用〕[Object of the invention, embodiments and effects]
