Patent ID: 7302695

Claim:
A slot-in type optical disk player comprising a disk guide device to guide an optical disk onto a central portion of a turntable regardless of a diameter of the optical disk, the disk guide device comprising: a chucking plate provided in a main body of the optical disk player, with a first hinge shaft provided on a rear portion of the chucking plate to allow the chucking plate to be rotated upward and downward around the first hinge shaft relative to the main body, and a chuck provided on a front portion of the chucking plate to compress an upper surface of the optical disk seated on the turntable; a guide arm provided on a predetermined portion of a lower surface of the chucking plate to be moved forward and rearward, with a guide protrusion provided on each of both ends of a lower surface of the guide arm to guide the optical disk, inserted into the optical disk player, onto the central portion of the turntable; a select arm provided on a predetermined portion of an upper surface of the chucking plate, so that the select arm is rotated around a second hinge shaft thereof on the chucking plate at a predetermined angle, the select arm being coupled at a first end thereof to the guide arm, with a protrusion guide hole comprising a first guide hole part and a second guide hole part and provided on a second end of the select arm, and a spring coupled to a predetermined portion of the select arm to rotate the select arm in a predetermined direction, thus moving the guide arm forwardly; a push arm provided on a predetermined portion of the lower surface of the chucking plate while being coupled to the second hinge shaft of the select arm, so that the push arm is rotated around the second hinge shaft of the select arm at a predetermined angle and is linearly and horizontally moved under the guide of the second hinge shaft, with a stop protrusion provided on a predetermined portion of the push arm and inserted into the protrusion guide hole of the select arm while being seated in one of the first and second guide hole parts of the protrusion guide hole, and a spring coupled to a predetermined portion of the push arm to move the push arm in a direction opposite to a pushing direction thereof; and a push lever coupled to a third hinge shaft provided on a predetermined portion of the main body, with a contact pin extending downward from a predetermined portion of the push lever, so that, when a large-diameter optical disk is inserted into the optical disk player, the push lever is rotated around the third hinge shaft of the main body while the contact pin is in contact with the large-diameter optical disk, thus pushing the push arm inwardly, thereby allowing the stop protrusion of the push arm to be removed from the first or second guide hole parts of the select arm, with a spring coupled to a predetermined portion of the push lever to return the push lever to an original position thereof when the contact pin is released.
