Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is an optical pickup rod that holds and mechanically fixes the optical pickup. This is related to the storage device.

0002

[Conventional technology]

In recent years, optical pickup locks have been developed to protect optical pickups from shock during transportation. The device uses an optical pickup that moves up and down to reduce costs and simplify locking operations. is configured to reach lock mode using

0003 An example of the conventional optical pickup lock device mentioned above is shown below with reference to the drawings. explain about.

0004 3 and 4 show the configuration of a conventional optical pickup lock device. Figure 3 In FIG. 4, 9 is an optical pickup, and 10 is a rotor provided on the optical pickup 9. 11 is a movable base that holds the optical pickup 9, 12 is a movable base 11, which is provided with an inclined groove portion 12a. Also, 1 3 is a motor, 14 is a belt for transmitting driving force, and 15 is a fixed base. Bearing parts 15a and 15b that support the moving base 11 and a locking hole 1 shown in 16. A lock pin is provided that fits into the optical pickup 9 to lock the optical pickup 9.

[0005] In the above configuration, when the motor 13 rotates, the cam 12 rotates, The movable base 11 descends along the inclined groove portion 12a provided in the cam 12. So Due to its downward movement, the locking hole 10 fits into the locking pin 16 and the optical pin Backup 9 is locked.

[0006] Also, when the motor 13 is reversed, the movable base 11 rises and the locking hole 1 0 and the lock pin 16 are disengaged, allowing the optical pickup 9 to move freely. .

[0007]

[Problem that the idea aims to solve]

However, the conventional optical pickup lock device as described above is The position where the pickup is locked is restricted to one place, and the optical pickup must be inserted before locking. This has the problem of having to be moved to a predetermined position.

[0008] In view of the above-mentioned conventional problems, the present invention has been developed to solve the problems of the conventional technology. Optical pick that can be guided to the lock position and locked no matter where it is on the track. This was made for the purpose of providing an up-lock device.

[0009]

[Means to solve the problem]

In order to solve the above problems, the optical pickup lock device of the present invention is an optical pickup lock device. an optical pickup that plays back discs, and a movable device that supports the optical pickup and can be raised and lowered. a base; a cam that raises and lowers the movable base; and a cam that raises and lowers the movable base; an inclined shape that guides and holds the optical pickup and mechanically fixes it when the optical pickup is lowered; It has ribs.

0010

[Effect]

The present invention uses the above-mentioned configuration to cover the entire stroke of the optical pickup. Regardless of the position, when the movable base is lowered, the slanted ribs provide light. This allows the pickup to be guided to the lock position and locked.

[0011]

【Example】

Refer to FIGS. 1 and 2 below for an example of the optical pickup lock device of the present invention. This will be explained in detail with reference to the following. Figures 1 and 2 show an optical pick-up in an embodiment of the present invention. This figure shows the configuration of the pop-lock device.

0012 In FIGS. 1 and 2, 1 is an optical pickup, and 2 is an optical pickup provided in the optical pickup 1. 3 is a movable base that holds the optical pickup 1; 4 is a movable base; cam that raises and lowers base 3; 5 is a motor; 6 is a belt for transmitting driving force; 7 is a fixed The base includes bearing parts 7a and 7b that rotatably support the movable base 3, Equipped with an inclined rib 8 that guides and holds the roller 2 when the optical pickup 1 is lowered. ing.

[0013] The operation of the optical pickup lock device configured as above is explained below. explain about. First, the motor 5 rotates from the state where the movable base 3 is in the raised position. Then, the cam 4 rotates, and the movable base 3 protrudes into the inclined groove 4a provided on the cam 4. The movable base 3 descends along the pin 3a. And due to its downward movement, The roller 2 provided on the optical pickup 1 always moves along the inclined rib 8 in the x direction. The optical pickup 1 is held at a predetermined position y by the inclined rib 8, locked. Also, when the motor 5 reverses, the movable base 3 rises and the roller -2 and the inclined rib 8 are separated, and the optical pickup 1 can move freely.

[0014] As described above, according to this embodiment, in what position is the optical pickup when the performance is stopped? However, due to the movement of the movable base descending due to disc unloading, the It can be localized to the position of the camera. Also, when unloading a disk, The optical pickup is locked at the lock position directly below the innermost circumference of the disk. Therefore, the next time you load the disc into the playing position, the optical pickup is always located at the innermost position of the disc, allowing you to quickly read the TOC of the disc and play. can be done quickly.

[0015]

[Effect of the idea]

As described above, the present invention allows the optical pickup to move at any position in its entire stroke. Even when the movable base is lowered, the inclined ribs prevent the optical pickup from moving. Optical pickup lock device that can guide and lock the pickup to the lock position This is something that can be provided.
