ABSTRACT:
A sound reproducing device is disclosed in which an index tracking portion formed on a record disc consists of a notch on the continuous flange of rotational periphery of a record disc unit. A center pin of the device is normally urged outside of a casing by a spring which also urges an index setting arm with a push button type index setting rotary knob supported on the tip end of said center pin. An index setting portion consists of a plurality of openings formed in the casing and arranged along the rotational plane of said record disc unit. The index setting arm has a resilient engaging hook on its lower tip end, the engaging hook directed toward the rotational cetner of the record disc unit. The engaging hook engages with the flange of the record disc unit where a specific index setting portion is selected by rotation of the push button type index setting knob. Pushing the index setting knob down makes the engaging hook pass through an index setting openings. The center pin keeps a speaker unit out of engagement with a pickup such that the pickup returns to the starting point of sound reproduction. The engaging hook returns through the index tracking portion when the index tracking portion comes on the engaging hook by rotational movement of the record disc unit, causing the center pin to retract so as to impart stylus pressure to the stylus by returning the speaker unit by a stylus pressure spring.
