ABSTRACT:
A continuous repeating type simplified sound reproducing device including on its casing, a fixed locking lever having a locking face parallel to the plane of rotation of a record disc and a rotating locking lever on the record disc which rotates together with the record disc and is able to enter under the locking face of the fixed locking lever only when the record disc is placed at its retracted position. At least one of the locking faces of the two locking members are arranged to have a face length corresponding to the angle of rotation sufficient to maintain the record disc at its retracted position until the record disc has completely returned to the starting point of sound reproduction. By virtue of this construction, satisfactory returning motion of this continuous repeating type sound reproduction device can be assured by a comparatively simplified construction.
