Abstract
It is an object of he present invention to provide a disc transfer mechanism that allows a disc to be reliably installed and removed. As shown in FIG. 3, this invention includes a damper means provided between a base (2) and a tray (1) to reduce the moving speed of the tray (1) using the urging force of a spring (3). The damper means comprises a first damper (45) interposed between the tray (1) and the base (2) to reduce the tray moving speed during all the tray moving steps and a second damper that operates, separately from the first damper (45), during the step of delivering a disc set on a turntable to the tray.
Claims5
A disc transfer mechanism for setting on a turntable a disc placed on a tray in response to the drawing-out and -back of said tray, comprising:
- a spring provided between said tray and a base that supports said tray in the direction in which said tray is drawn out and back, in order to urge the tray in the direction in which it is pushed out from the base;
- and
- a damper means provided between the base and said tray, and adapted to reduce the speed of the tray movement effected by the urging force of said spring;
- said damper means comprising:
- a first damper interposed between said tray and the base that supports the tray in the direction in which the tray is drawn out and back, in order to reduce the tray moving speed during all the steps in which the tray is moved by the urging force of the spring;
- and
- a second damper that operates during the step of delivering the disc set on the turntable to the tray.
A disc transfer mechanism comprising:
- an elevating mechanism for elevating and lowering a turntable in response to the drawing-out and -back of a tray to allow the turntable to be installed on and removed from a disc placed on the tray;
- a disc receiving member provided at the front end of said tray and adapted to freely slide in the direction in which the tray is drawn out and back, and having a positioning protrusion that can abut on the outer circumference of the disc being loaded while said disc receiving member is urged toward the internal end of the tray;
- said disc receiving member being arranged to abut on the fixed side when the central hole of the disc placed on the tray reaches a position over said turntable and to move toward the front end of the tray relative to the movement of the tray toward the internal end thereof;
- a spring provided between said tray and the base that supports said tray in the direction in which it is drawn out and back, in order to urge said tray in the direction in which it is pushed out from the base;
- and
- a damper means provided between the base and said tray in order to reduce the speed of the tray movement effected by the urging force of the spring;
- said damper means comprising:
- a first damper interposed between said tray and the base that supports the tray in the direction in which the tray is drawn out and back, in order to reduce the tray moving speed during all the steps in which said tray is moved by the urging force of the spring;
- and
- a second damper interposed between the base that supports the tray in the direction in which the tray is drawn out and back and an elevating mechanism for elevating and lowering the turntable in response to the drawing-out and -back of the tray, in order to operate during the step of delivering the disc set on the turntable to the tray.
A disc transfer mechanism comprising:
- an elevating mechanism for elevating and lowering a turntable in response to the drawing-out and -back of a tray to allow the turntable to be installed on and removed from a disc placed on the tray;
- a disc receiving member provided at the front end of said tray and adapted to freely slide in the direction in which the tray is drawn out and back, and having a positioning protrusion that can abut on the outer circumference of the disc being loaded while said disc receiving member is urged toward the internal end of the tray;
- said disc receiving member being arranged to abut on the fixed side when the central hole of the disc placed on the tray reaches a position over said turntable, and to move toward the front end of the tray relative to the movement of the tray toward its internal end;
- a spring provided between said tray and the base that supports said tray in the direction in which it is drawn out and back, in order to urge said tray in the direction in which it is pushed out from the base;
- and
- a damper means provided between the base and said tray in order to reduce the speed of the tray movement effected by the urging force of the spring;
- said damper means comprising:
- a first damper attached to the base that supports the tray in the direction in which the tray is drawn out and back, and engaging with a first rack formed to extend from the front end to internal end of said tray;
- and
- a second damper attached to said base and engaging with a second rack formed only at the front end of the tray.
A disc transfer mechanism for setting on a turntable a disc placed on a tray in response to the drawing-out and -back of said tray, comprising:
- a spring provided between said tray and a base that supports said tray in the direction in which said tray is drawn out and back, in order to urge the tray in the direction in which it is pushed out from the base;
