Abstract: PURPOSE:To receive both FM stereophonic broadcasting and sound multiplex broadcasting with a receiver, by installing a leaf switch to the drum of a variable condenser and switching an FM demodulator and TV sound multiplex demodulator in accordance with a receiving frequency. CONSTITUTION:A leaf switch 4 is installed to the drum of a variable condenser and the switch 4 is short-circuited when the receiving frequency is 90-108MHz. Since the leaf switch 4 does not operate when the receiving frequency is 76- 90MHz, this receiver outputs an FM multiplex demodulator 3 side. When the receiving frequency becomes 90-108MHz as in the case of TV sound multiplex broadcasting, the leaf switch 4 is short-circuited and a TV sound multiplex demodulator 5 side is outputted by switching a switching circuit 6. Therefore, by making the variable condenser variable, stereophonic reproduction is made when FM stereophonic broadcasting is received and, when TV sound multiplex broadcasting is received, stereophonic reproduction is made in the case of stereophonic broadcasting and duplex reproduction is made in the case of two-language broadcasting.

Abstract: PROBLEM TO BE SOLVED: To accurately detect a moving position by avoiding adverse influence as much as possible even when looseness exists between a rotary shaft (moving element) and rotary plate (detector) using a pair of light emitting and receiving means. SOLUTION: A rotary plate 13 is fixed to a rotary shaft 12. The plate 13 is formed of acrylic resin having light permeability, formed on the inner peripheral side with a reference reflecting surface 15 having a predetermined radius and formed on the outer peripheral side with a spiral detecting reflecting surface 17. Both the surfaces 15, 17 are opposed in the state inclined at 45 deg., the light from an upper LED 18 is totally reflected on the surface 15, further totally reflected on the surface 17 via the plate 13, and the light is outputted toward downward. This position is detected by a PSD (semiconductor position detector) 19. Since the radial position of the surface 17 is different in response to the rotary position of the plate 13, the rotary position can be detected by the pair of LED 18 and PSD 19.  Even if there is looseness in the rotary state of the plate 13 or the rotary state is eccentrically deviated, the position can be accurately detected.

At the time correction, a reset signal also enters a reset control circuit 18 at the same time. The time correction is accomplished by setting the minute hand 16 and the hour hand 17 to desired positions as the setting lever intermeshed with the minute wheel 13 is rotated manually, by which the center wheel and pinion iwht cannon-pinion 12 and cannon pinion 24 are slided. Thereafter, when the hand operation is started by releasing the time correction by the time announcement or the like, the second hand 15 begins to start from the just second position and therefore the accurate time correction may be accomplished.
