Description

Optical disc data access device with two feeding modes

technical field

The utility model belongs to an optical disc data access device with two ways of feeding discs, in particular to a disc data accessing device of a suction-type disc data accessing device with the function of flipping the cover and withdrawing discs, and having both. Advantages of optical disc data access device.

Background technique

The existing optical disc data access device uses a replaceable optical disc as a data recording medium, so it must have the function of advancing/ejecting the disc. The traditional feeding/removing method is nothing more than any one of the tray type, suction type or flip type, which are incompatible with each other and each has its own application.

The slot-in type optical disc data access device is the easiest way to insert/eject discs. The slot-in type opening can be allowed to face any direction, which is widely favored by users. It is most commonly used in optical disc data access devices on cars. However, along with the diversification of the appearance of optical disks, various optical disks with irregular appearances are gradually popularized. Restricted by the congenital limitation of the slot-in mechanism, these irregular-shaped optical discs cannot be used on the slot-in type optical disc data access device, which is a major obstacle to the application of the slot-in type optical disc data access device.

The clamshell type optical disc data access device has the opposite usage characteristics. Its usage is the most complicated, but it has the highest compatibility with various special-shaped optical discs, and can almost load optical discs of any shape. As can be seen from the above, the existing optical disc advance/eject technology has the dilemma that it cannot achieve the best of both worlds.

Please refer to FIG. 1 and FIG. 2 , the existing standard 8cm and 12cm optical disks 10a and 11a can be used by general optical disk reading devices. Please refer to FIG. 3 and FIG. 4 , the existing irregular business card-shaped optical discs 12 a and Christmas tree-shaped optical discs 13 a can only be used in flip-type optical disc reading devices and loaded manually.

It can be seen from the above that the above-mentioned existing optical disc data access device obviously has inconvenience and disadvantages in actual use, and needs to be improved.

Aiming at the above-mentioned problems of the prior art, the inventor has devoted himself to research and combined with the application of theories, and finally proposes a utility model which is reasonably designed and effectively improves the above-mentioned shortcomings.
