摘要： A signal pickup device in a rotary recording medium reproducing apparatus comprises a turntable placed thereon with a rotary recording medium recorded with an information signal as variations in geometrical configuration, for rotating the rotary recording medium, a reproducing stylus provided at a tip end of a cantilever, for making contact with and sliding against a recorded region of the rotary recording medium upon reproduction to reproduce the information signal, a resonator having a resonance frequency which varies in accordance with the above variations in geometrical configuration, and a conductive ribbon having one end connected to the reproducing stylus and the other end connected to the resonator to electrically connect an electrode of the reproducing stylus with the resonator, where the conductive ribbon is in a curved and bent state upon reproduction of the rotary recording medium. The conductive ribbon has a length such that the conductive ribbon is put into an extended state from the above curved and bent state when the reproducing stylus is lowered below the height position of the rotary recording medium, to restrict the lowering of the reproducing stylus at a height position higher than that of the turntable.

摘要： A reproducing apparatus is capable of performing special reproduction of information signals recorded on a rotary recording medium. The information signals are recorded in either spiral track turns or concentric tracks. The reproducing apparatus comprises a detector for generating a rotation detection signal having a frequency which varies proportionally to the rotational speed of the rotary recording medium. A special signal generator generates a special reproduction synchronizing signal and a generator generates an external control signal based on a signal which is obtained by variably controlling the frequency of the special reproduction synchronizing signal. A manual switch varies the frequency of the special reproduction synchronizing signal by controlling the control signal generator responsive to an output code signal corresponding to a position of the manual switch. The manual switch is positioned at a predetermined neutral position to produce the external control signal once every one rotation of the rotary recording medium, to repetitively reproduce the same track. The manual switch varies the frequency of the external control signal to vary, with predetermined steps, a speed of picture motion of the reproduced information signal, corresponding to positions of the manual switch.

摘要： An apparatus for automatically reproducing recorded signals from a rotary recording medium, in accordance with the mode in which signals were recorded. The reproducing apparatus comprises a micro-computer which produces a two-bit mode control signal and a one-bit muting signal. The one-bit muting signal puts one of two processing circuits in a non-operational state, so that the other of the two processing circuits can perform the signal processing in accordance with the mode specified by the two-bit mode control signal. Four codes constituted by the two-bit mode control signal are commonly used to specify four reproducing modes of a video rotary recording medium and four reproducing modes of an audio rotary recording medium.
