摘要： The record player comprises a container, a turntable mounted in the container and rotatable by an electric motor, a speaker movable about a pivot towards the turntable under the bias of a spring, and a tone arm having a stylus and being movable with the speaker towards the turntable against the bias of a second spring so as to engage a record in use on the turntable. The second spring biases the tone arm radially outwardly of the turntable. The turntable has a central upstanding boss and a reset member is mounted for angular movement relative to the boss about the axis of the boss. The reset member and the upper end of the boss have cam surfaces biased into engagement with each other by a third spring. The reset member has a radially outwardly extending arm engageable with the speaker or a part connected thereto as the tone arm moves towards the center of the turntable such that when the arm engages the speaker or the part, the member is prevented from rotating with the boss and hence the two cam surfaces are angularly moved relative to one another. The cam surfaces are so shaped that such relative angular movement results in an axial movement of the reset member away from the turntable to pivot the speaker away from the turntable against the bias of the first spring so as to allow the second spring to move the tone arm away from and radially outwardly of the turntable.
