ABSTRACT:
A simplified sound reproducing device having external output shafts disposed beneath the plane of rotation of a record disc and at positions corresponding to the starting point of sound reproduction of each record groove. Each of the external output shafts actuates predetermined external components for action corresponding to the content of the recorded item in the record groove. A transmission is provided for connecting a center pin to each of the external output shafts. The transmission includes a driving wheel fixed around the center pin, a revolvable bearing frame member which is journally connected for rotation with the center pin when under engagement with a coupling member, a planetary shaft carried by the revolvable bearing frame member, a planetary gear wheel supported by the planetary shaft capable of movement in an axial direction and rotated by meshing with the driving wheel. A pair of guide members fixedly disposed to the center pin, one positioned axially in front of and the other behind the driving wheel to hold the planetary wheel from both sides and to urge it to move axially together with the driving wheel, and driven wheels fixedly coupled to each external output shaft capable of meshing with the planetary wheel only when the pickup is supplied with stylus pressure. A coupling member is constructed such that the planetary shaft can be stationary, regardless of the rotation of the center pin, when the pickup is loaded with stylus pressure.
