PURPOSE:To secure the operation of a clutch by slanting the line, connecting the rotation link point between the 2nd operating plate and rotary link piece to the intermediate support shaft of the rotary link, to the ejection direction of an engagement- disengagement part in the lengthwise direction of the 2nd operating plate. CONSTITUTION:With push button 9 depressed, channel selecting member 1 moves forth to permit engagement step part 40 to press against disengagement part 41 and while a couple of rotary link pieces 33 and 34 rotate easily in their slanting direction, disengagement part 41 is disengaged from engagement step part 40; and then rotary disk 36 rotates counterclockwise and slanting plate 26 is struck up to separate transmission wheel 24 from transmission wheel 27, thereby releasing the clutch. When channel selecting member 1 further advances, memory pin 3 while operating on the slanting edge of notch part 46 agrees with its peak and in the process, transverse plate 13 transverses corresponding to the rotation angle of regulation plate 4; and the variable element of variable tuning part 17 is varied according to its stroke to perform the channel selection. Push-button 9 restitutes by being released from the depression. In this state, rotating manual knob 21 adjusts variable tuning part 17. |
