Abstract
An optical disk drive includes a main body and a tray. A tray locking mechanism includes a base fixed to the tray, a locking device installed on the base for combining with or separating from a stop pin of the main body, a transmission device installed on the base for driving the locking device, and a control device installed on the base for stopping the transmission device. When the locking device combines with the stop pin of the main body, the tray can be locked to the main body, and when the transmission device drives the locking device to be separated from the stop pin of the main body, the tray can eject from the main body and the control device can stop the transmission device from rotating.
Claims10
A tray locking mechanism for use in an optical disk drive, the optical disk drive comprising a main body and a tray, the tray locking mechanism comprising:
- a base fixed to the tray;
- a locking device installed on the base for combining with or separating from a stop pin of the main body;
- a transmission device installed on the base for driving the locking device;
- a control device installed on the base for stopping the transmission device;
- and
- an emergency ejection device for ejecting the tray, comprising an emergency ejection element sheathed on the tray for pushing the locking device and an elastic element sheathed on the emergency ejection element;
- wherein when the locking device combines with the stop pin of the main body, the tray can be locked to the main body, and when the transmission device drives the locking device to be separated from the stop pin of the main body, the tray can eject from the main body and the control device can stop the transmission device from rotating.
An optical disk drive comprising:
- a main body comprising a stop pin;
- a tray for sliding between a locking position and an ejecting position corresponding to the main body;
- and
- a tray locking mechanism installed on the tray for combining with the stop pin of the main body when the tray is in the locking position and for separating from the stop pin device of the main body when the tray is in the ejecting position, wherein the tray locking mechanism comprises:
- a base fixed to the tray;
- a locking device installed on the base for combining with or separating from the stop pin of the main body;
- a transmission device installed on the base for driving the locking device;
- and
- a control device installed on the base for stopping the transmission device;
- and
- an emergency ejection element sheathed on the tray for pushing the driving part of the locking shaft and an elastic element sheathed on the emergency ejection element.
