Abstract: Clutch means for changing inductance of a push-button tuner which is compact in size and adapted for use with a tape recorder. The mechanism includes flat slidable cam plates provided with cam portions at the front portions thereof, which are arranged horizontally and slidably through holes of side walls and a push-button assembly slidably arranged in front and rear walls, which is equipped with a channeling plate pivotably mounted thereon, the position of which may be set at a desired angle by means of the operation of a manual shaft when a clutch mechanism is engaged.

Abstract: A clutch mechanism for a push-button type tuner is adapted for use in a tuner having cores shiftable with respect to coil bodies, the tuner being devised to maintain the varied position of the core. The mechanism includes a disc unitarily connected to a rotatable shaft, the disc being sandwiched between a lever support and plural levers which function to bring the lever support into engagement or disengagement with the disc upon the depression or release of one of the push-buttons, whereby smooth clutching or declutching operation is obtained.
