ABSTRACT:
The present fine tuning device comprises a fine tuning shaft mounted concentrically around a main channel selecting shaft supported in a chassis base. A plate spring member is disposed on the chassis for thrust biasing the fine tuning shaft. A gear member is arranged for transmitting the fine tuning movement from the fine tuning shaft to a fine tuning screw. The fine tuning shaft is provided with a radially extending flange and a peripheral gear, and the transmitting gear member is provided with a first gear engageable with the peripheral gear of the fine tuning shaft and a second gear engageable with the fine tuning screw. The plate spring member supports the rotating transmitting gear member whereby the axial direction of movement may be changed or shifted by deformation of the plate spring member. In this arrangement, when the fine tuning shaft is pushed to change the shape of the plate spring member, the first gear of the transmitting gear member is securely engaged with the peripheral gear of the fine tuning shaft. At the same time, the second gear of the transmitting gear member is engaged with a pinion gear of the fine tuning screw so as to permit a memory fine tuning for one of the tuning coil units selected by the main channel selecting shaft.
