- This cam groove 43 Since the first cam groove 53A for feeding the large optical disk 1 and the second cam groove 53B for feeding the small optical disk 1 are configured, a plurality of cam grooves are formed on the first drive cam 44.
- the disk feeding cam portion 51 can be configured with a simple structure in which the projection 52 is provided on the connecting member 423. Therefore, the cost for manufacturing the disc feeding cam portion 51 can be reduced.
- the first drive cam 44 also serves as a drive cam for moving the turntable 23 close to and away from the optical disc 1, the number of parts can be reduced, and the size of the disc device can be reduced. And low cost can be achieved.
- the connecting member 423 is formed in a substantially flat plate shape, it is possible to reduce the thickness of the disk device.
- roller-shaped contact portion 421A is provided at the tip of the arm 421, even if the optical disc 1 is pushed from the slot 1 OA with a strong force, the contact portion 421 A that contacts the optical disc 1 is provided. Since it rotates, the peripheral edge of the optical disk 1 is not damaged.
- the second disk delivery mechanism is the disk guide mechanism 41, but in the present invention, the second disk delivery mechanism is provided separately from the disk guide mechanism 41.
- the second disk delivery mechanism is the disk guide mechanism 41, it is not limited to the configuration of the above embodiment.
- the disk gas in the above embodiment, a separate motor and gear mechanism may be provided to move the disc guide mechanism 41 forward and backward.
- the disk diameter detection mechanism 42 is configured to detect the size of the optical disk 1 by the arm 421 whose one end is in contact with the optical disk 1 and whose other end is rotatable.
- a rod that can move forward and backward along the slot 10A is provided, and a means for interlocking the forward and backward movement of the rod via a cam mechanism or the like may be employed.
- the disk guide mechanism 41 is not limited to the configuration of a parallel link including two first links 411 and one second link 412.
- the disk guide mechanism 41 has coils at both ends of the second link 412. It is possible to connect the springs directly! / ⁇ .
- the present invention can be applied to three or more types of optical discs 1 exemplifying two types of 8 cm and 12 cm as different types of optical discs 1 and one type of optical disc 1 having the same size.
- the apparatus main body 10 provided with the slot 10A for inserting and ejecting the optical disk 1, the turntable 23 that is provided in the substantially central part of the apparatus main body 10 and rotationally drives the optical disk 1, And a disc ejection mechanism 43 for ejecting the optical disc 1 arranged on the turntable 23 toward the slot 10A.
- the disc ejection mechanism 43 is a first disc delivery mechanism provided on the inner side of the apparatus body 10.
- the first disc feed mechanism 61 and the second disc feed mechanism provided on the back side and the entrance side of the slot 10A respectively make it small. Since discharging disc 1 to the outside Te transfer from Tante one table 23 through slot 10A, even without a pair of rollers across the front and back surfaces of the optical disc 1, moreover, to determine the size of the diameter of the optical disk 1 Even if no switches are provided, the small optical disc 1 can be ejected from the slot 10A to the outside.
- the present invention provides a recording medium drive in which a slot for inserting and ejecting a disk-shaped recording medium is provided in the apparatus main body, and a drive unit for rotationally driving the disk-shaped recording medium is provided at a substantially central portion inside the apparatus main body. Available for equipment.
