であった。First, the elastic member 115 is used to stabilize the urging force applied to the guide shaft 104 within the range of the adjustment stroke and to secure the shock resistance for holding the impact load applied to the guide shaft 104 when it is applied. It has been difficult to provide both.

立して付与することが困難であった。When a strong impact is applied to the guide shaft 104, the elastic member 115 is greatly deformed when the spring constant of the elastic member 115 is small, and the guide shaft 104 is
This causes a problem that the elastic member 115 loses the urging force due to the elastic member 115 being plastically deformed. On the other hand, when the spring constant of the elastic member 115 is large, the rigidity against an external load increases, but the guide shaft 104 can be urged against the screw 113 with a stable urging force in a desired adjustment stroke range by the screw 113. It was difficult. It has been difficult to provide the elastic member 115 with these two characteristics of stabilizing the urging force and ensuring impact resistance.

ースが増大し、装置の大型化を招いていた。In FIG. 9, supporting members 118 and 119 are required for supporting the guide shaft 104 in the y direction, and other means not described for supporting in the x direction are required. Further, for supporting the elastic member 115 in the x and y directions, it is necessary to form the locking groove 110 separately from the support means for the guide shaft 104. As described above, since the support mechanisms for supporting the guide shaft 104 and the elastic member 115 are separately provided, not only the number of parts and the number of steps are increased, but also the space required for disposing the support mechanism. And the size of the apparatus has been increased.

Between the guide shaft 104 and the elastic member 115.
Cannot be urged in a fixed direction in the y direction, so it is not known which of the support members 118 and 119 the guide shaft 104 will contact. For this reason, there is a problem that a reference for positioning the guide shaft 104 in the y direction cannot be obtained, and the positioning accuracy is deteriorated.

い。The optical head 3 is provided for the disk 1 in two directions orthogonal to each other in the radial direction X and the tangential direction Y of the disk 1.
The angle between the surface of the optical head 3 and the optical axis 3a of the optical head 3 is detected, and it is determined whether each angle is 90 degrees. When each angle is 90 degrees, a favorable recording / reproducing operation can be realized as an optical disk device, and it is not necessary to adjust the tilt of the optical head 3. However, when the inclination of the optical disk in the radial direction X or the tangential direction Y is not 90 degrees, the inclination of the optical head 3 must be adjusted.

And the optical head 3 supported by the guide shaft 5, the inclination θT in the tangential direction Y changes. By this operation,

きさの小さい板バネ構成を実現できる。Next, the operation of the elastic member 16 when adjusting the inclination of the optical axis 3a will be described. In FIG. 5, when the lifting member 14 is tightened for tilt adjustment, the lifting member 1
The guide shaft 5 abutting on the tip of 4 is lifted by the lifting member 14 in the direction of the stopper abutting portion 15a. The elastic member 16 that urges the guide shaft 5 so as not to be separated from the elevating member 14 is lifted and deformed in the same direction as the guide shaft 5. At this time, the stopper 15 is not fixed to the stopper receiver 9a by screws or the like, but is supported by the first stopper receiver 9a only by engagement by the pair of hooks 15b and 15c. Therefore, the engaging portion has a slight degree of freedom of rotation, and not only the elastic member 16 but also the entire stopper 15 rotates about the contact point between the first hook portion 15b and the first stopper receiver 9a. Further, the second hook 15c prevents the stopper 15 from dropping from the first stopper receiver 9a by pulling the stopper 15 in a direction that hinders rotation of the entire stopper 15. At this time, the stopper 15 made of an elastic body is deformed as a whole and disperses the stress generated in the elastic member 16 to the entire stopper 15, so that the elastic member 16 is more elastic than the case where the elastic member 16 is fastened and fixed to the chassis 9. Even if the size of the member 16 is the same, the leaf spring force can be reduced, that is, the spring constant can be reduced. Normally, in order to reduce the spring constant of the leaf spring, it is necessary to increase the distance between the free end and the fixed end, which increases the size of the entire leaf spring. With the above configuration, the spring constant of the elastic member 16 can be reduced, and a small-sized leaf spring configuration can be realized.

ことが可能となる。When an impact larger than the urging force of the elastic member 16 is received in the Z + direction shown in FIG. 6, the guide shaft 5 is released from the tip of the elevating member 14 and moves in the Z + direction. However, when the guide shaft 5 moves by a predetermined amount or more, the guide shaft 5 collides with a stopper contact portion 15a provided integrally with the elastic member 16 and its movement is regulated. Dropping and plastic deformation of the elastic member 16 can be prevented. This eliminates the need to support the impact load with the urging force of the elastic member 16, thereby reducing the spring force of the elastic member 16, and the difference in the urging force for urging the guide shaft 5 within the adjustment stroke range of the lifting member 14. Becomes smaller, so that the guide shaft 5 can be urged with a stable urging force.

とを防止できる。When an impact is applied in the Z-direction shown in FIG. 5, the guide shaft 4 comes into contact with the tip of the elevating member 13 and further displacement is prevented. It can be prevented from dropping from the receiver 9b. Similarly, when an impact is applied in the Y + direction and the Y- direction shown in FIG. 5, the guide shaft 4 comes into contact with the first guide surface 17a or the second guide surface 17b, and further displacement is prevented. Therefore, it is possible to prevent the guide shaft 4 from dropping from the second stopper receiver 9b.

For this reason, the elastic member 16 can set the spring constant to be small, and can provide a disk device capable of urging the guide shafts 4 and 5 with a stable urging force.

, And hook portions 15b provided at both ends thereof,
Since the engaging portion 15c engages with the first stopper receiver 9a at 15c, the engaging portion has a rotational degree of freedom, and when the elastic member 16 is deformed, the entire stopper 15 is also deformed, so that the stress generated in the elastic member 16 can be suppressed to a small level. The spring constant can be set smaller than the size of the member 16, and a small disk device that does not require the large elastic member 16 can be provided.
