- optical disks such as CD CD-ROM, CD-R, CD-RW and DVD-ROM DVD-R, DVD-RW DVD + R DVD + RW DVD-RAM, MO Disks (magneto-optical disks), magnetic disks and the like can be mentioned.
- the lever when the lid is opened, the lever is rotated by the urging force of the urging means, and the contact portion of the lever comes into contact with the disk end surface. Can be controlled.
- the lever is rotated by the first releasing means formed on the lid against the urging force of the urging means, so that the abutting portion of the lever is moved from the end face of the disk.
- the separation prevents the rotation of the disk from being hindered. Therefore, the disc can be braked according to the opening / closing operation of the lid.
- the rotation stopping mechanism is constituted by the lever, the urging means and the first releasing means provided on the lid, the configuration of the rotation stopping mechanism of the disk when the lid is opened can be simplified. It comes out.
- the contact portion for braking the rotation of the disk is brought into contact with the disk end face by the rotation of the lever. Therefore, the moving direction of the contact portion during the braking of the disk is the rotation direction of the lever. And According to this, the direction of the amount of force acting on the lever at the time of braking can be the same as or opposite to the direction of action of the urging force by the urging means. Therefore, the amount of force applied to the lever can be controlled by the urging force of the urging means.

- the lever when the contact portion of the lever comes into contact with the rotating disk, the lever is rotated by the rotating disk in a direction opposite to the rotating direction of the lever when the disk is braked.
- the lever receives a moving acting force (component), but this acting force (component) can be suppressed by the urging force of the urging means provided on the lever. That is, the acting force (component) for rotating the lever in the direction away from the disc force during disc braking can be controlled by the urging force of the urging means. Therefore, when the disc is braked, the contact portion can be reliably brought into contact with the disc end surface, and the pressing force of the contact portion against the disc end surface can be adjusted by the strength of the urging force by the urging means. Can be.

- the urging means is a magnetic member that attracts or repels the lever by a magnetic force.
- the biasing force for rotating the lever is generated by the magnetic member. Therefore, when the lever rotates with the opening of the lid and the contact portion comes into contact with the disk end surface, the largest force is applied. Power can be applied to the lever. Therefore, when the lid is opened, Since the force for bringing the contact portion into contact with the end face can be increased, the rotation of the disk can be reliably braked.
- the lid In the closed state of the lid, the urging force acting on the lever is minimized.
- the lid is opened when a disk is loaded into the storage unit and when the disk is removed from the storage unit, so that the lid is more closed than in the open state.

- FIG. 5 shows a rotating state of the lever 6 when the lid 13 is opened.
- figure 6 shows a side view of the lid 13 and the lever 6 with the lid 13 opened.

- the contact surface 632 of the arm 63 comes into contact with the end surface of the optical disc 4 stored in the optical disc storage section 20. Thereby, the friction with respect to the rotation of the optical disk 4 increases, and the rotation of the optical disk 4 is stopped.
- the contact surface 632 formed on the arm portion 63 is contacted while being inclined with respect to the rotational tangent direction of the optical disc 4. More specifically, with respect to the optical disc 4 rotating in the direction of arrow C in FIG. 5, the contact surface 632 facing the end face of the optical disc 4 is brought into contact with the end face of the optical disc 4 so as to face the rotation direction. . This allows any part of the contact surface 632 to contact the end surface of the optical disc 4 even if there is some error in the diameter of the rotating optical disc 4. Therefore, the rotation of the optical disc 4 can be reliably stopped even for the optical discs 4 having different diameters.
- the arm 63 of the lever 6 that has been turned is brought into contact with the end of a projection 20F and an opening 20C (see FIG. 3) projecting outward from the lower surface of the upper case body 14, and The rotation range is restricted.
- the protrusion 13B formed on the lever 13 contacts the surface 642 formed on the arm 64 of the lever 6 via the opening 20B.
- the surface 642 is formed so as to be inclined so that the dimension of the extending portion 641 in the extending direction becomes larger as it goes downward, so that as the lid 13 is closed, the protrusion 13B becomes 7 comes into deep contact with the surface 642, and as shown in FIG. 7, the lever 6 rotates in the direction of arrow B2 in FIG.
- the rotation of the lever 6 is opposed to the urging force of the coil spring 7 in the direction of arrow A1. Accordingly, the contact surface 632 of the contact portion 631 is separated from the end face force of the optical disc 4, so that the braking on the optical disc 4 can be released.
- the optical disk 4 rotates in the direction of arrow C in FIG. 5, and the lever 6
- the disc 4 rotates in the direction of arrow B1 around the projection 20D and is pressed against the end face of the optical disc 4.
- the lever 6 receives an acting force (component) outward from the rotating optical disc 4 in the circumferential direction around the center of the optical disc 4.
- the direction of this acting force (component) is opposite to the direction of arrow B1 in FIG. 5, and is the direction of arrow B2 in FIG. 7 in which the lever 6 rotates when the lid 13 is closed.
- the lever 6 abutting on the end face of the rotating optical disc 4 acts on the end face of the optical disc 4 due to the acting force (component) from the optical disc 4. Due to the biasing force of the spring 7, the lever 6 is kept in contact with the end face of the optical disc 4 against this acting force (component). According to this, the acting force (component) acting on the lever 6 from the rotating optical disc 4 during braking of the optical disc 4 is controlled by the urging force of the coil spring 7 for rotating the lever 6 in the direction of arrow B1. can do. Therefore, the contact surface 632 of the lever 6 can be reliably brought into contact with the end surface of the optical disc 4 to brake the optical disc 4, and the contact force of the coil spring 7 can be applied to the end face of the optical disc 4. The pressing force of the lever 6 to be touched can be adjusted.
- the braking member force that brakes the rotation of the optical disk 4 moves linearly toward the center of the optical disk, and is pressed against the end face of the optical disk 4, A force that is known to stop the rotation of the disk.
- Such a braking member is applied with a circumferential outward force from the rotating optical disk 4, that is, a force in a direction different from the moving direction of the braking member. Therefore, it is impossible to control the acting force (component) at the time of braking the optical disc 4 and the posture of the braking member, which causes rattling of the braking member.
- the acting force (component) applied to the lever 6 is controlled by the coil spring 7. And the play of the lever 6 can be suppressed. Further, such an acting force (component) can be controlled by the urging force of the coil spring 7, so that the configuration of the rotation stop mechanism 5 can be simplified.
