Therefore, the position restriction in the left-right direction is performed.

  Next, when a recording / reproduction start switch (not shown) is turned ON, the clamp base 10 moves from the standby position shown in FIG. 1 in the direction of arrow B (in the direction orthogonal to the moving direction of the optical pickup 2), It moves to the clamp position shown in FIG.

  Next, the first and second centering means 8a and 8b start sliding in the arrow A 'direction, and the third and fourth centering means 8c and 8d start in the arrow A direction almost simultaneously. The third and fourth centering means 8c and 8d move to a position where they abut against the outer periphery of the disk 4 and continue to slide, so that the third and fourth centering means 8c and 8d move to the outer periphery of the disk 4. The disk 4 can be moved in the direction of arrow A while supporting.

  When the disk 4 reaches the centering completion position shown in FIG. 3, the first to fourth centering means 8a to 8d abut against a stopper (not shown) and stop the sliding operation. The stopper is provided so as to stop at a centering position where the center of the disk 4 moved by the first to fourth centering means 8 a to 8 d matches the center of the turntable 1.

  Thereafter, as shown in FIG. 2, the traverse base 5 rotates about the support shaft 5a in the direction of arrow C, the turntable 1 moves through the opening 3b to the recording / reproducing position, and the disk 4 moves to the turntable 1. It is lifted on the disk mounting surface. As a result, the clamper 11 is attracted to the disk mounting surface of the turntable 1 by the magnetic force, and the disk 4 is clamped by the turntable 1 and the clamper 11 to be in a recordable / reproducible state as shown in FIG.

  As shown in FIGS. 3 and 4, when the traverse base 5 completes moving to the recording / reproducing position, the first and second centering means 8a and 8b slide in the direction of the arrow D ', and the third and fourth centering means 8c and 8d slide in the direction of arrow D and retreat to a position away from the outer periphery of the disk 4 placed on the turntable 1. In the present embodiment, the first to fourth centering means 8a to 8d are moved to the first position shown in FIG. At this time, the disk 4 is held on the turntable 1. Then, the turntable 1 rotates to rotate the disk 4 so that information can be recorded on and reproduced from the disk 4. If the first to fourth centering means 8a to 8d are separated from the outer periphery of the disk 4 placed on the turntable 1, they are retracted to any position between the first position and the second position. May be.

  The disk loading operation is performed in the order of clamp base movement, centering, and traverse movement (clamping). However, the order is not necessarily required, and the order is changed if the disk can be moved to the clamped state. Also good.

  In the present embodiment, the order in which the centering means 8a to 8d start to slide after the disk 4 is placed on the disk placement surface 3a starts almost simultaneously. First, the first and second centering means After the slides 8a and 8b start to reach the centering position and come into contact with a stopper (not shown) and stop, the third and fourth centering means 8c and 8d start to slide and the disc 4 It is good also as a structure which transfers to, reaches | attains a centering position, abuts on a stopper (not shown), and stops. In addition, the third and fourth centering means 8c and 8d first start sliding, transfer the disk, reach the centering position, abut against a stopper (not shown), and then stop. The second centering means 8a and 8b may start sliding, reach the centering position, and come into contact with a stopper (not shown) to stop.

  Next, a case where the disk 4 is removed from the apparatus will be described.

  When a disk ejecting switch (not shown) is turned on while the disk 4 is at the recording / reproducing position, the rotation of the turntable 1 is stopped and the rotation of the disk 4 is stopped. Then, the first to fourth centering means 8a to 8d slide from the first position to the second position that supports the outer periphery of the disk 4. Thereafter, the traverse base 5 rotates in the direction of arrow F about the support shaft 5a, and moves from the recording / reproducing state to the standby state shown in FIG. Accordingly, the disk 4 held by the turntable 1 and the clamper 11 is separated from the disk mounting surface of the turntable 1 and the clamper 11. Thereafter, the first and second centering means 8a and 8b slide in the direction of arrow D ', and the third and fourth centering means 8c and 8d slide in the direction of arrow D (standby position direction) with the disk 4 placed thereon. The disk 4 is moved to a position where the disk 4 abuts on the rib 3c. Further, when the third and fourth centering means 8c and 8d slide in the direction of the arrow D, the third and fourth centering means 8c and 8d are separated from the outer peripheral portion of the disk 4 until the first position shown in FIG. Move (At this time, the clamp base 10 is still in the position of FIG. 3). At approximately the same timing, the first and second centering means 8a and 8b move to the first position shown in FIG. Next, the clamp base 10 moves from the clamp position shown in FIG. 3 in the direction of arrow E and moves to the standby position shown in FIG. Thereby, the disk 4 can be taken out.

  Note that the above-described disk ejecting operation is performed in the order of releasing the clamp, releasing the centering, and retracting the clamp base. However, the order is not necessarily required. It may change.

  In the present embodiment, the slide start order of the centering means 8a to 8d when moving from the centering position of the disk 4 to the disk removal position starts sliding almost simultaneously. First, the first and second The centering means 8a and 8b start sliding, reach the first position (position in FIG. 1) and stop, and then the third and fourth centering means 8c and 8d support the disk 4. A configuration may be adopted in which the slide is started to reach the first position (position in FIG. 1) and stop. First, the third and fourth centering means 8c and 8d start sliding, move while supporting the disk, reach the first position and stop, and then first and second The centering means 8a and 8b may start sliding to reach the first position and stop.

  Next, the mounting operation of the cartridge 9 will be described with reference to FIGS.

  As shown in FIG. 5, the cartridge 9 can be mounted on the disk mounting surface 3a and the rib 3c in a state where the first to fourth centering means 8a to 8d are in the first position. Then, in a state where the cartridge 9 is placed on the disc placement surface 3a and the rib 3c by the user, by a regulating means (not shown) such as a wall provided at the left and right ends in the planar direction of the disc placement surface 3a, Position restriction in the left-right direction is made. At this time, the first and second centering means 8a and 8b are not in contact with the upper end portion 9c of the cartridge 9 and are in a separated state. The third and fourth centering means 8c and 8d are not in contact with the lower end portion 9a of the cartridge 9 and are separated from each other, but the upper ends of the third and fourth centering means 8c and 8d are ribs. The third and fourth centering means 8c and 8d may be positioned so as to be flush with the bottom 3c ′ of 3c.

  Next, when a recording / reproducing start switch (not shown) is turned ON, the clamp base 10 moves from the standby position shown in FIG. 5 in the direction of arrow H (in the direction orthogonal to the moving direction of the optical pickup 2), It moves to a clamp position where the center of the turntable 1 and the center of the clamper 11 substantially coincide (not shown).

Next, the first and second centering means 8a and 8b slide in the direction of arrow I, and the third and fourth centering means 8c and 8d slide in the direction of arrow G (direction toward the center of the turntable 1). The first and second centering means 8a and 8b are in contact with the upper end portion 9c of the cartridge 9 and the third and fourth centering means 8c and 8d are in contact with the lower end portion 9a of the cartridge 9. The sliding operation of the first to fourth centering means 8a to 8d is stopped.
Here, as the means for stopping the sliding operation when the first to fourth centering means 8a to 8d abut on the cartridge 9, for example, the centering means is constituted by a slip structure and is brought into contact with the cartridge 9. There is means for stopping the sliding operation by slipping. The cartridge 9 is already positioned at the centering position by being placed on the rib 3c. Thereby, the vertical positioning of the cartridge 9 can be performed.

  Thereafter, the shutter 9b provided on the cartridge 9 is opened by a shutter opening / closing mechanism (not shown).

  Next, as shown in FIG. 6, the traverse base 5 rotates about the support shaft 5a in the direction of the arrow J, the turntable 1 moves through the opening 3b to the recording / reproducing position, and the disc 4 moves to the turntable. 1 is lifted on the disk mounting surface. Along with this, the clamper 11 is attracted to the disk mounting surface of the turntable 1 by the magnetic force, and the disk 4 is clamped by the turntable 1 and the clamper 11 to be in a recording / reproducing state. Then, the turntable 1 rotates to rotate the disk 4 so that information can be recorded on and reproduced from the disk 4.

  Next, a case where the cartridge 9 is taken out from the apparatus will be described.

  When a disk ejection switch (not shown) is turned on while the disk 4 in the cartridge 9 is at the recording / reproducing position, the rotation of the turntable 1 stops and the rotation of the disk 4 stops.

  The first and second centering means 8a and 8b are moved in the direction of arrow G from the position where the first to fourth centering means 8a to 8d are in contact with and supported by the upper end portion 9c and the lower end portion 9a of the cartridge 9. The third and fourth centering means 8c and 8d slide in the direction of arrow I, and the first to fourth centering means 8a to 8d move away from the cartridge 9 and release the support. In addition, the sliding amount of the 1st-4th centering means 8a-8d at this time is slight.

  Next, the traverse base 5 rotates about the support shaft 5a in the direction opposite to the arrow J, and moves to a standby state as shown in FIG. Accordingly, the disc 4 held by the turntable 1 and the clamper 11 is detached from the disc placement surface of the turntable 1. Next, the clamp base 10 moves from the clamp position in the direction opposite to the arrow H, moves to the standby position shown in FIG. 5, and the cartridge 9 can be taken out.

  As described above, according to the first embodiment, the opening 3b through which the turntable 1 can be inserted and moved is provided in a part of the front cover 3, and the first to fourth centering means are provided above and below the front cover 3. By providing 8a to 8d, when the disk 4 is placed on the disk placement surface 3a and the rib 3c, the center of the disk 4 can be automatically transferred so as to match the center of the turntable 1. Therefore, it is not necessary to position and mount the disk 4 finely, and it can be easily mounted. Further, since the disk is supported from four directions, the disk mounting range in which centering can be performed is wide, and the degree of freedom of disk mounting can be increased.

  In this embodiment, as means for clamping the disk 4 to the turntable 1, means for moving the clamp base 10 parallel to the disk placement surface using the clamp base 10 is used. Other means such as translation or rotation from the direction may be used. Further, a means for clamping only by the turntable 1 without using the clamp base 10 may be used.
