ABSTRACT:
A weight means disposed in a casing of a phonograph is capable of being swung and urged normally in a predetermined direction. The weight means is associated with a lifting means. The lifting means is able to mechanically lift a sound transmitting member to move it in a direction away from a record disc against which, said transmitting member is urged under stylus force by means of a stylus force spring.
According to this simple and correct mechanism, the stylus force exerted on the sound transmitting member is released by means of a shock without fail. Hence, a pickup will return to a starting point of sound reproduction by a return spring. The weight means is then able to return to its original location so that the necessary stylus force may be imparted again to the pickup through the sound transmitting member.
