Claims

[Scope of Claim for Utility Model Registration] (1) A disk loading device equipped with a disk table on which a disk is placed so as to be able to enter and exit a disk loading position at the back of the cabinet through an opening window on the front surface of the cabinet, comprising: a spiral damper rotatably supported on one side of the movement path of the spiral damper, having a spiral spring wound in the insertion direction of the disk table, with a gear provided on the circumferential surface meshing with a locking gear formed on the disk table; When the disk table is inserted, a lock arm is biased and supported so that one end engages and locks the side of the disk table, and is capable of reciprocating in the direction of contacting and separating from the other end of the lock arm. and an eject lever that is supported by the lock arm and disengages and rotates one end of the lock arm from the engagement position by the forward movement, and the spring damper is biased in the disk eject direction by releasing the engagement and lock. - A device for inserting and extracting a disk table, characterized in that it is linked to the lock arm so that it can be rotated. (2) At the end of the disk table in the insertion direction, there is a clamp member supported rotatably in a direction to clamp or unclamp the loaded disk, and this clamp member locks or locks the disk table by a lock arm. 2. The disk table insertion/removal device according to claim 1, wherein the disk table insertion/removal device is connected to the lock arm so as to perform the rotation operation in conjunction with the rotation in the lock release direction. (3) The clamp member and the lock arm are cam-coupled, and the cam action in response to the rotation of the lock arm causes the clamp member to clamp the disc in conjunction with the insertion/removal operation of the disc table.
3. The disk table insertion/removal device according to claim 2, wherein the disk table insertion/removal device is configured to rotate in an unclamping direction. (4) Claim (3) characterized in that the clamp member has an inclined cam surface, and a cam follower provided on the lock arm is slidably engaged with this inclined cam surface.
) Insertion/ejection device for the disk table described in ). (5) The other end of the lock arm extends from the side of the disk table in a lateral and oblique angular direction, and the other end can come into contact with the inclined surface formed at the end of the eject lever; 2. The disk table insertion/removal device according to claim 1, further comprising a spring that urges the eject lever in the backward movement direction.
