摘要： An interconnecting member which operatively connects a pushbutton slide with either one of a pair of tuning slides comprises a flat body portion which has its one end pivotally connected with the pushbutton slide. At its other end, the body portion is provided with means for mechanically engaging with one of the pair of tuning slides selectively. The body portion is also provided, at said other end, with means for engaging with shift means which shifts the interconnecting member from one operational position to the other operational position. The interconnecting member moves angularly across the surface of the pushbutton slide in response to an operation of the shift means.

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.
