All the disc positioning mechanism element forces including the left centering lever 111 and the disc detection lever 112 are outside the disc 100 mounting area Id, and the mechanism can be configured at the same height as the discs 100 and 120. Therefore, the thickness of the disk loading device can be reduced (thinner) as compared with a device in which a disk positioning mechanism is arranged above the disks 100 and 120.
- the biasing spring 10 is shared. It is possible to reduce the cost. Even if the right centering lever 108 and the left centering lever 111 are not very rigid, the right centering lever 108 provided with the trigger lever 109 is directly locked by the disc detection lever 112. The right centering lever 108 will be pinched by force, and the rotation axis 108h of the trigger lever 109 will not move. Therefore, the positioning accuracy of the disk 120 is improved and no seating error occurs.
- the right centering lever 108 and the left centering lever 111 can be made of low-cost, low-stiffness materials, and the cost can be reduced.
- the control walls 101c and 101d for locking the disc detection lever 112 and the trigger lever 109 are provided, and the right centering lever 108 and the left centering lever 111 are provided.
- the chassis 101 is provided. That is, as shown in FIG. 29, all of the disc detection lever 112, the trigger lever 109, the right centering lever 108, the left centering lever 111, and the restriction portions 101c and 101d are provided in the sub chassis 101. As a result, there is no mounting error between the sub-chassis 101 and the support substrate 15, so that the centering accuracy of the disk 120 can be improved and a seating error can be eliminated.
- the same effect can be obtained even if the disc detection lever 112, the trigger lever 109, the right centering lever 108, the left centering lever 111, and the restricting portions 101c and 101d are all provided on the support substrate 15. Further, in the second embodiment of the present invention, the contact pin 109a of the trigger lever 109 that contacts the outer periphery of the disk 120 is engaged with the restriction wall 101c. As a result, the accuracy of the lock position of the right centering lever 108 is improved, so that the accuracy of the disc detection lever 112 with respect to the restriction wall 101d can be improved, and the lock of the right centering lever 108 can be stabilized to improve the quality.
- the present invention is not limited to the above-described embodiments, and can be implemented in various other modes.
- the right centering lever (8, 108), the trigger lever (9, 109), the left centering lever (11, 111), and the disc detection lever (12, 112) Although it is configured to be supported by a shaft and move by a rotating operation, these elements may be configured to move linearly (linear operation) by a slide mechanism or a link mechanism.
- the engagement pins (8b, 108b) of the right centering lever (8, 108), the engagement pins (9a, 109a) and the drive pins (9b, 109b) of the trigger lever (9, 109), the left centering lever ( 11 and 111) engagement holes (l lb, 11 lb) and the disc detection levers (12, 112) of the disc detection pins (12a, 112a) The invention is not limited to this. As long as the position fulfills each function, it may be provided at any position in each lever.
- the present invention is useful for a thin disk loading apparatus that can share a large-diameter disk and a small-diameter disk.
