摘要： An improved push button type tuner is disclosed which assures that an operator can selectively tune to one of two preset radio frequencies merely by actuating a single push button. The push button type tuner includes a plurality of channel selecting mechanisms each of which comprises an actuating shaft with a push button fixedly secured thereto and two channel selecting shafts disposed by both the sides of the actuating shaft. The actuating shaft and the channel selecting shafts are supported so as to move between the fore inoperative position and the rear operative position. The actuating shaft includes a main gear and a shifting lever which performs shifting operation in such a manner that the pair of channel selecting shafts are alternately displaced to the rear operative position at every time when a cycle of foreward and rearward movements of the actuating shaft between the fore inoperative position and the rear operative position is achieved. Each of the channel selecting shafts includes a follower gear adapted to mesh with the main gear when the it is displaced to the rear operative position and a channel selecting dog mounted thereon to move in the axial direction as it is rotated. The channel selecting dog serves to select a frequency of the variable tuning device as the channel selecting shaft is displaced in the axial direction.

摘要： A mechanism for changing inductance of a push-button tuner which is constructed to be compact and flat in size as to be 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 a front and a rear walls, which is equipped with a channeling plate pivotable thereon the position of which may be set at a desired angle by means of the operation of manual shaft when a clutch mechanism is closed. With the advancement of the push-button plate against a coil spring arranged at the end thereof, the projections positioned on the channeling plate set at desired angle collide with the cam portions of the slidable cam plates intermittently whereby the slidable cam plates are shifted conversely and the intermittent shifting movement of the cam plates thus created are transmitted to the foot of a core carriage by turns through a rotation means connected therewith with the result that the cores mounted on the carriage are shiftable back and forth with respect to the coil bodies whereby the variation of inductance is obtained.

摘要： In a pushbutton tuner in which a tuning carriage is designed to be laterally positioned by a selected one of a plurality of carriage levers which are designed to slip with respect to the carriage as the carriage is moved, a reduced degree of force is required for moving the carriage by making the levers normally loosely associated with the carriage so that relative motion between them involves little or no friction, but in which the carriage lever operative at any given time to position the carriage is urged into snug engagement with the carriage thereby to eliminate backlash and achieve high accuracy tuning.

摘要： 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.

摘要： A first selector is to be set up to cause the control tone produced by a variable frequency oscillator to have a first selected frequency. A second selector is set up to cause the control tone to have a second selected frequency. A third selector set at a third selected frequency determines which of the first or second selectors is operable to control the oscillator. The second selector is operative to cause the control tone to have the second selected frequency when the first and third selectors are set in corresponding conditions, and the first selector is operative to cause the control tone to have the first selected frequency when the first and third selectors are set in noncorresponding conditions.
