Abstract
The present invention relates to a disc ejecting apparatus for ejecting a disc by utilizing a pick-up drive motor. It is proposed to simplify the construction of the disc ejecting apparatus. A slip mechanism is provided in a route leading from the pick-up drive motor to a pick-up, and in the last stage of restoration of the pick-up to an initial position the disc ejecting mechanism is connected to the pick-up drive motor.
Claims3
Disc ejecting apparatus for ejecting a disc by a disc ejecting mechanism with a driving force of a pick-up drive motor for reciprocally moving a pick-up, having:
- a first gear driven by the driving force of said pick-up drive motor;
- a pick-up support for supporting said pick-up;
- a second gear for reciprocally moving said pick-up support, said pick-up support being disposed coaxially with said first gear and able to be moved to an end position in which said pick-up is positioned in an initial position;
- a friction member inserted between said first and second gears, said friction member transmitting the driving force from the first gear to said second gear and providing a slip action;
- a third gear for selectively engaging the first gear and transmitting the driving force of the pick-up drive motor to said disc ejecting mechanism;
- a stopper adapted to be in contact with said pick-up support to stop the pick-up to said initial position when the pick-up support is restored to said end position;
- and
- a connecting member for supporting said third gear and engaging said third gear with said first gear in response to the movement of the pick-up support in a last stage of restoration of the pick-up to the initial position, thereby to transmit the driving force of the pick-up driving motor to the disc ejecting mechanism, wherein:
- after said pick-up is restored to the initial position, said pick-up is held to the initial position by said slip action.
