Tray used in an optical disk drive
View Patent ↗The present invention relates to a tray used in an optical disc drive. At least two aligning means arranged in the tray for marking an aligning line at a front side and a back side of the tray, respectively. The aligning line is used for determining the dimensional accuracy of each component located on the front side and back side of the tray, respectively.
1. A tray used in an optical disc drive comprising:
a tray portion having at least two aligning means for defining a plurality of non-collinear aligning lines on a front side and a back side of the tray, respectively;
wherein the aligning lines are used for determining a dimensional accuracy of each component located on the front side and back side of the tray portion, respectively.
2. The tray as claimed in claim 1 , wherein the at least two aligning means are defined by at least two through holes passing through and formed by the tray portion.
3. The tray as claimed in claim 1 , wherein at least two aligning means are at least two prominent means projecting outward from the front side and back side of the tray.
4. The tray as claimed in claim 3 , wherein the prominent means is a spur.
5. The tray as claimed in claim 1 , wherein the tray is a tray made of a plastic material.
6. The tray as claimed in claim 1 , wherein the tray portion includes a carrier plane for carrying an optical disk, a protruding point is located at a center of the carrier plane, and the protruding point is configured to determine whether the components located on the tray meet proper dimensional requirements.
7. The tray as claimed in claim 6 , wherein the components include at least one of the carrier plane and a longitudinal rack.
