Abstract

PURPOSE:To prevent the generation of a data error due to dirt by providing a case having a filter in a shape to surround the whole device in the external periphery of a frame. CONSTITUTION:A base plate 1 is fitted through a rubber vibration insulator 11 to a frame 8, and a case 10 being equipped with a filter 9 in the shape to surround the whole device is arranged in the external periphery of the frame 8. Consequently, since air to the inside of the device flows in and out through the filter 9, the circumstances near an optical disk and an optical head 6 are cleanly held, and the dirt does not attach or piles up. Thus, the data error due to the dirt can be prevented from being generated.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an optical disc device, and particularly to improvements in its housing.

(Prior Art) Conventionally, hard magnetic disk devices have generally adopted a closed structure, while optical disk devices have generally adopted an open structure.

However, in recent years, in consideration of the negative effects of dust that adheres to and accumulates on optical discs, improvements have been made to the air flow configuration, or to a double-write closed structure to bring the cleanliness closer to that of a closed structure. The current situation is that

(Problem to be Solved by the Invention) The conventional optical disk device described above does not fundamentally have a completely sealed structure, but instead has an open structure that communicates with the outside air. Therefore, there is a drawback that floating dust from the atmosphere flows into the inside of the optical disk device and accumulates on the surface of the objective lens of the optical disk or optical head, causing data errors when recording or reproducing information. .

An object of the present invention is to provide a mechanical unit and a mechanism for driving an optical disc. To eliminate the above-mentioned drawbacks by providing a case having a filter that covers the entire frame around the outer periphery of the frame provided with the L-child circuit, and to provide a Natisk device configured to prevent data errors from occurring due to dust. be.

(Means for Solving the Problems) An optical disc device according to the present invention includes a spindle, an optical head, a carriage, a base plate, a frame,
This configuration includes a filter.

The spindle is for supporting and rotating an optical disk on which information is recorded, and the optical head is for writing/reading information to/from the optical disk.

The ridge is for holding and fixing the optical head, and the base plate is the spindle and carriage! II
-It is the largest one to be mounted, and the frame is to support the base plate.

The filter is a slit that wraps around the entire outer periphery of the frame and covers the entire frame.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a front view of a mechanism section showing an embodiment of an optical disc device according to the present invention.

In FIG. 1, 1 is a base plate, 2 is a spindle, 3 is an optical disk, 4 is a spindle hub, S is a carriage, 6 is an optical head, 7 is a magnetic circuit, 8 is a frame, 9
10 is a filter, 10 is a case, and 11 is a vibration-proof rubber.

Figure 1? For reference, a spindle 2 fixed on a base plate 1 has an optical disk 3 mounted on a spindle hub 4 of the spindle 2, and a dedicated O motor (not shown).
, ) drive the rotation of the optical disc 3. The carriage S carries an optical head 6 and is held on a rail (not shown) fixed on the base plate 1 so as to be able to linearly reciprocate in the radial direction of the optical disk 3.

In order to drive the linear reciprocating motion of the carriage S, a magnetic circuit 7 constituted by a permanent magnet is electrically connected to the base plate 1. The base plate 1 is connected via vibration-proof rubber 11.
, is attached to the frame 8, and the whole frame is attached to the outer circumference of the frame 8. A case 10 having a surrounding filter 9 is arranged.

Therefore, since air flows into and out of the optical disc device through the filter 9, the atmosphere near the optical disc 3 and the optical head 6 is kept clean, and no dust is deposited.

(Effects of the Invention) As explained above, the present invention provides a case having a filter having a shape that intercolors the entire frame around the outer periphery of the frame, thereby keeping the atmosphere around the optical disc and the objective lens of the optical disc clean. Further, there is an effect that dust does not adhere and accumulate on the objective lens surface, data errors do not occur during information recording/reproduction, and reliability can be maintained high.
