Optical disc drive
View Patent ↗An optical disc drive with a positioning mechanism suitable for reading data from an optical disc is provided. The optical disc drive comprises a casing, a tray, a reading module and a rail. The tray is disposed inside the casing. The tray has a first positioning part and is suitable for withdrawing from the casing. The reading module is disposed on the tray and is suitable for reading data from an optical disc. The rail is disposed inside the casing and is suitable for withdrawing from the casing when driven by the tray. The rail has a second positioning part. When the tray is ejected from the casing, the location of the tray relative to the casing is maintained through the first positioning part and the second positioning part. Therefore, an optical disc can be put on the tray or removed from the tray with ease.
1. An optical disc drive suitable for reading data from an optical disc, comprising:
a casing;
a tray disposed inside the casing, wherein the tray has a first positioning part and is suitable for ejecting from the casing;
a reading module disposed on the tray, wherein the reading module is suitable for reading the data in the optical disc; and
a rail disposed inside the casing, wherein the rail is suitable for withdrawing away from the casing when driven by the tray, the rail has a second positioning part such that the relative position between the tray and the casing when the tray is ejected from the casing is maintained through the first positioning part and the second positioning part.
2. The optical disc drive of claim 1 , wherein the first positioning part is a protrusion and the second positioning part is a recess or a hole.
3. The optical disc drive of claim 1 , wherein the first positioning part is a recess or a hole and the second positioning part is a protrusion.
4. The optical disc drive of claim 1 , wherein the first positioning part and the second positioning part are protrusions.
5. The optical disc drive of claim 1 , wherein the optical disc drive further comprises:
a control circuit board disposed inside the casing; and
a flexible printed circuit for connecting the reading module with the control circuit board.
6. The optical disc drive of claim 1 , wherein the reading module further comprises:
a turntable disposed on the tray for gripping and spinning the optical disc; and
an optical pick-up disposed on the tray suitable for moving along a track-seeking path to read the data from the optical disc.
7. The optical disc drive of claim 1 , wherein the rail further comprises:
an outer rail disposed inside the casing; and
an inner rail forming a sliding engagement with the outer rail, wherein the tray forms a sliding engagement with the inner rail.
8. The optical disc drive of claim 1 , wherein the tray has an arm such that the first positioning part is located on the arm.
