Zusammenfassung:To provide an operation mechanism which is able to not only avoid addition of great constraint torque to a component but also improve productivity, and can be freely configured regardless of a shape of the component and constitute the component which can be immune to a force generated in the case of contact.SOLUTION: An operation mechanism comprises: a first gear meshed with a plurality of gears; a hook installed rotatably on a side face of the first gear; and a unidirectional gear which has directivity in a shape of the gear so as to be meshed with the hook when the first gear is rotated in a specific direction. The unidirectional gear and a cam are connected by a common shaft so as to be rotated integrally, and a spring-up fitting is disposed so as to be in contact with the hook when a rotating position of the first gear comes to a maximum compressing position of a throw-in spring. The hook is rotated while being sprung up by the contact of the hook and the spring-up fitting, such that the meshing with the unidirectional gear is temporarily avoided.SELECTED DRAWING: Figure 1 【課題】部品に大きな拘束トルクが加わることを回避できることは勿論、製作性が良好で、かつ、部品の形状によらず自由に構成でき、接触時に発生する力に耐えうる部品を構成することが可能な操作機構を提供する。【解決手段】複数の歯車と噛み合う第一歯車と、該第一歯車の側面に回転可能に設置されたフックと、前記第一歯車と同軸上に、前記第一歯車が特定の方向に回転したときに前記フックと噛み合うように歯車の形状に指向性を持たせた一方向ギヤとを備え、前記一方向ギヤとカムを共通のシャフトで接続することで一体となって回転するように構成し、前記第一歯車の回転位置が前記投入ばねの最大圧縮位置となったときに前記フックと接触するように跳上金具を配置し、前記フックと前記跳上金具の接触により前記フックを跳ね上げながら回転させることで、前記一方向ギヤとの噛み合いを一時的に回避させるように構成されていることを特徴とする。【選択図】図1
