Abstract
An apparatus for reproducing a disc includes an operating member for manually operating an unloading tray from the body of the apparatus when the disc is clamped. The operating member is supported on a shaft and fixed to the main chassis and is thus capable of rotating around the shaft. The operating member is also provided with a protrusion for permitting a cylindrical cam to support the mechanical unit when the disc is being driven. With a supporting member of the operating member and the cylindrical cam positioned on the front side of the mechanical unit, fluctuations in disc can be reduced.
Claims9
An apparatus for reproducing a disc, the apparatus comprising:
- a mechanical unit including a mechanism for driving the disc;
- a cylindrical cam having a guide groove adapted for supporting said mechanical unit, the guide groove guiding said mechanical unit in order to move said mechanical unit between a first position and a second position, the first position enabling said disc to be driven, the second position disabling said disc from being driven;
- and
- an operating member adapted to cooperatively move with said cylindrical cam, said operating member permitting a user to manually move said cylindrical cam in order to move said mechanical unit from said first position to said second position when said mechanical unit is inoperable, the operating member having a supporting portion for supporting said mechanical unit positioned at said first position when said mechanical unit is positioned at said first position.

- and
- an operating member adapted to cooperatively move with said cylindrical cam, said operating member permitting a user to manually move said cylindrical cam in order to move said mechanical unit from said first position to said second position when said mechanical unit is inoperable, the operating member having a first contacting portion and a second contacting portion, each of the first and second contacting portions being configured to transfer power to said cylindrical cam;
- wherein all contacting portions simultaneously contact the cylindrical cam when transferring the power, the simultaneous contact thereby optimizing an operating load applied to said operating member.
