Mechanism mechanism for optical disc recorder / player

The present invention is directed to an apparatus for adjusting the mechanism of an optical disk recorder / player, and more particularly, to an apparatus for adjusting the mechanism of an optical disk recorder / player for minimizing the mechanism of other mechanisms for high-speed high-density (CVD) of an optical disk recorder / player.

Recently, as shown in FIG. 1, a disc recording / reproducing apparatus has a base 1, a spindle motor 10 provided on an upper surface of the base 1, and an optical disk rotatably provided on the upper surface of the spindle motor 10. As shown in FIG. A shuck portion (2) consisting of a turntable (20) to be mounted thereon; It consists of a pick-up part 3 which plays an optical disk mounted on the turntable 20 and moves forward and backward along guide shafts 5 and 5 'installed on the upper surface of the base 1.

However, in the above optical disc recording / reproducing apparatus, the accuracy of the inclined angle of the optical disc information surface and the laser optical axis of the pickup section becomes very important in the mechanism state according to the tendency of high speed and high density. There is a problem that adjustment is impossible with respect to the laser beam axis because it is fixed to (1).

The present invention solves the above-mentioned shortcomings, and by providing a shoe adjusting device in the lower part of the spindle motor, the accuracy of the inclined angle of the optical disk information surface and the laser beam axis of the pickup part in the mechanism state is improved in accordance with the tendency of high speed and high density. It is an object of the present invention to provide a mechanism mechanism for controlling an optical disk recorder / player.

In order to achieve the above object, the present invention has a base, a spindle motor which is installed on the upper surface of the base, and a spindle portion which is rotatably installed on the upper surface of the spindle motor and a turntable for mounting the optical disk; In the compact disc player consisting of a pickup unit for playing the optical disc mounted on the turntable and moving forward and backward along the guide shaft installed on the upper surface of the base, a shoe adjusting device is installed in the lower portion of the spindle motor to provide a surface attitude of the turntable. It is configured to be adjusted, the shoe adjusting device is formed with a guide protrusion protruding at a predetermined interval on the base; A guide plate for fitting to the guide protrusion is formed at both ends with respect to the spindle motor, and first and second screw holes are formed at opposite ends of the guide groove, respectively; The first screw hole and the fixing screw to be screwed to the base by the force of the spring is installed, the adjusting screw is fitted to the second screw hole.

1 is a simplified view of a conventional optical disc recording / reproducing apparatus;

FIG. 2 is a plan view briefly showing a mechanism wake adjusting device of the inventive optical disc recorder / player; FIG.

Figure 3 is a side view showing a partial extract of the mechanism of the mechanism mechanism of the present invention optical disk recorder / player.

The present invention is described in detail with reference to the accompanying drawings as follows.

First, the same names and shapes as in the prior art are given the same candidates, and description thereof is omitted.

Figure 2 is a side view showing a partial extract of the mechanism mechanism for adjusting the mechanism of the optical disk recorder / player of the present invention.

The present invention, as shown in Figure 1, the base 1, the spindle motor 10 is installed on the upper surface of the base (1), the spindle motor 10 is installed rotatably on the upper surface so that the optical disk is mounted A shuck portion 2 composed of one turntable 20; The compact disc player, which comprises an pickup unit 3 which plays an optical disc mounted on the turntable 20 and moves forward and backward along the guide shafts 5 and 5 'installed on an upper surface of the base 1, has a conventional structure. As shown in FIG. 2, however, a technical characteristic is provided in that the shoe adjusting device 30 is installed at the lower portion of the spindle motor 10 so that the surface attitude of the turntable 10 is adjusted.

The shrunk adjusting device 30 includes guide protrusions (1a) (1b) and protruding at a predetermined interval on the base (1) as shown in Figure 2; Guide grooves 31a and 31b for fitting to the guide protrusions 1a and 1b are formed at both ends with respect to the spindle motor 10, and are orthogonal to the guide grooves 31a and 31b. Control plates 31 each having first and second screw holes 31c and 31d formed at both ends thereof; The first screw hole 31c is provided with a fixing screw 33 which is screwed onto the base 1 by the force of the spring 32, and the adjusting screw 34 is inserted into the second screw hole 31d. Configured to be customized.

Reference numeral 4 in the drawings is a wire for supplying power to the pickup section 3 and the spindle motor 10.

Therefore, the mechanism shock adjusting device of the optical disk recorder / player configured as described above includes an adjusting device 30 for adjusting the inclined angle of the optical disk information surface and the laser beam axis of the pickup portion, that is, the adjusting plate of the shoe portion 2 ( When the adjusting screw 34 screwed to 31 is rotated in a clockwise or counterclockwise direction, the shuck portion 2 supports the fixing screw 33 installed to face the adjusting screw 34 as a supporting point. One side of the control plate 31 is raised or lowered according to the elastic force of the spring 32 that is formed on the fixing screw 33 to be properly adjusted.

As described above, the present invention can improve the accuracy of the inclined angle of the optical disc information surface and the laser beam axis of the pickup part in the mechanism state according to the tendency of high speed and high density by providing the shoe adjusting device in the lower part of the spindle motor.
