Abstract
There is provided an optical disc drive that can guide the center of an optical disc to the position of a spindle motor, while allowing the number of components to be reduced. A base frame includes a stopper portion that comes into contact with an outer edge of the optical disc having reached the position of a spindle motor and that restricts backward movement of the optical disc. A switch arm includes a contact portion located on a side opposite to the stopper portion across the optical disc having reached the position of the spindle motor, and the switch arm uses the contact portion to push the optical disc toward the stopper portion.
Claims11
An optical disc drive comprising:
- an insertion port configured to receive an optical disc;
- a spindle motor located behind and away from the insertion port;
- a mechanism configured to convey the optical disc from the insertion port to a position of the spindle motor via a conveying roller rotating about a first axis;
- a frame including a stopper portion configured to come into contact with an outer edge of the optical disc having reached the position of the spindle motor, to restrict backward movement of the optical disc;
- a bias member including a contact portion located opposite to the stopper portion across the optical disc having reached the position of the spindle motor, the bias member operating to rotate about a second axis, transverse to the first axis, such that the contact portion moves and urges the optical disc toward the stopper portion;
- and
- a movable member configured to move in response to a collision with the optical disc during a process in which the optical disc is conveyed toward the position of the spindle motor, wherein the movable member engages with the bias member and, when the optical disc reaches the position of the spindle motor, moves the bias member such that the contact portion moves away from the optical disc.
An electronic apparatus, comprising:
- a cabinet configured to house an optical disc drive including
- an insertion port configured to receive an optical disc,
- a spindle motor located behind and away from the insertion port,
- a mechanism configured to convey the optical disc from the insertion port to a position of the spindle motor via a conveying roller rotating about a first axis;
- a frame including a stopper portion configured to come into contact with an outer edge of the optical disc having reached the position of the spindle motor, to restrict backward movement of the optical disc;
- a bias member including a contact portion located opposite to the stopper portion across the optical disc having reached the position of the spindle motor, the bias member operating to rotate about a second axis, transverse to the first axis, such that the contact portion moves and urges the optical disc toward the stopper portion;
- and
- a movable member configured to move in response to a collision with the optical disc during a process in which the optical disc is conveyed toward the position of the spindle motor, wherein the movable member engages with the bias member and, when the optical disc reaches the position of the spindle motor, moves the bias member such that the contact portion moves away from the optical disc.
