    • A tuning device for a radio receiver comprises a manual tuning system to manually drive a variable capacitor and an automatic tuning system to drive the same by a motor, wherein the mechanism for transmitting a motive force of a manipulated tuning knob to the variable capacitor in the manual tuning mode is arranged in a mechanically independent relation with a motive force transmitting mechanism provided by a motor in the automatic tuning mode, and the selection of either one of the two transmitting mechanisms is effected by a clutch mechanism whose connection of either one of the two transmitting mechanisms to the variable capacitor is changed over by a touch switch electrically connected to the tuning knob of the receiver.
    • 用于无线电接收机的调谐装置包括手动驱动可变电容器的手动调谐系统和通过电动机驱动其的自动调谐系统,其中用于将操纵的调谐旋钮的动力传递到可变电容器的可变电容器的机构 手动调谐模式以与自动调谐模式中的电动机提供的动力传递机构以机械独立的关系布置,并且两个传动机构中的任一个的选择由离合器机构实现,离合器机构的连接 通过电连接到接收器的调谐旋钮的触摸开关切换到可变电容器的两个发送机构。
