Abstract
PURPOSE: To enable fine tuning and facilitate quick tuning, by providing a planet gear mechanism, which is put in or out of operation by weights to which centrifugal force acts, for an operating shaft which is rotated with a knob.
CONSTITUTION: In a tuning mechanism, a variable capacitor or the like is operated through a transmission shaft 25 and a transmission system not shown in the drawing, by rotating a knob 7. At the time of fine tuning, a sun gear 10 is rotated through an operating shaft 8 as the knob 7 is rotated at a relatively low speed. The rotation of the operating shaft 8 is transmitted with speed reduction to the transmission shaft 25 by a planet gear mechanism 9. When received frequency is to be changed far, the knob 7 is relatively quickly rotated to rapidly revolve the operating shaft 8. At that time, weights 17,... are displaced so that stop teeth 23, 24 are engaged with each other as soon as a shifting drum 13 is separated from the partition wall 16 of a frame 6. As a result, the revolution of the operating shaft 8 is transmitted with no change to the transmission shaft 25 through a fixed plate 14, the drum 13 and an internal gear 12.
