When the tray 12 is inserted in the direction A, the locking plate 63 comes into contact with a rib (not shown) projecting from the lower surface of the tray 12 and rotates to the unlock position. As a result, the rack 61 rotates clockwise together with the locking plate 63 and retreats from the moving path of the bearing 12 d formed on the tray 12.

Next, the operation of the shutter opening / closing mechanism 15 configured as described above will be described. FIG. 9 is a plan view showing a state in which the gear portion 56 of the first arm 32 meshes with the rack 61. FIG. 10 is a plan view showing an operation of opening the shutter 45c of the disk cartridge 45 with the movement of the tray 12.
FIG. 11 is a plan view showing a state where the shutter 45c of the disk cartridge 45 is fully opened.

[0041] When the rear side wall 23 of the tray 12 is the disc cartridge 45 is inserted into the tray 12 when in the P ₁ position (disc exchange position), with the engaging portion 45d of the shutter 45c as shown in FIG. 8 The mating roller 34 is engaged. When reaching the tray 12 is moved in the B direction P ₂ position as shown in FIG. 9, the gear portion 56 of the first arm 32 begins to mesh with the rack 61.

Further, when the tray 12 moves in the
_{At the third} position, since the gear portion 56 of the first arm 32 is engaged with the rack 61 as shown in FIG.
The first arm 32 rotates clockwise due to the relative displacement between the rack 2 and the rack 61, the second arm 33 connected to the first arm 32 by the burring caulking 51 rotates counterclockwise, and the guide pin 53 rotates. It moves in the C direction along the guide groove 58. Thus, the engagement roller 34 moves in the same direction to open the shutter 45c.

When the tray 12 moves in the direction B,
_{At the fourth} position, as shown in FIG. 11, the first arm 32 and the second arm 33 are pivotally displaced so as to extend in the C and D directions, and the shutter opening arm 31 becomes linear. In this state, the disk cartridge 45 is
Is fully opened, the disk 43 is exposed, and recording and reproduction by the optical pickup 25 are enabled. At this time, the disk cartridge 45 is located in front of the turntable 24, and is fully opened before the shutter 45c passes above the turntable 24.

When the shutter opening arm 31 is fully opened, the first arm 32 and the second arm 3 are actuated by the spring force of the torsion spring 60 biasing the first arm 32.
3 is urged so as to be in close contact with the rear side wall portion 23 of the tray 12, and the shutter is held in a fully opened state. In the position shown in FIG. 10, the other end 60b of the torsion spring 60 is located on the line L connecting the pin 47 and the one end 60a, so that the spring force of the torsion spring 60 acts on the pin 47. .

In the position shown in FIG. 11, the other end 60b of the torsion spring 60 is located on the left side of the line L connecting the pin 47 and the one end 60a.
Urges the first arm 32 to rotate clockwise. As a result, the first arm 32 and the second arm 33 are held in the shutter fully open state.

As described above, the gear portion 56 of the first arm 32 engages with the rack 61 provided on the base 22b of the housing 22 with the relative displacement when the tray 12 moves in the direction B, and the shutter is opened. The arm 31 can open the shutter 45c of the disk cartridge 45 in a short time, and can fully open the shutter 45c before the front end of the disk cartridge 45 reaches the turntable 24.

Therefore, the conventional disk cartridge 4
Although the insertion height position of 5 is set to a height position where the shutter 45c passes above the turntable 24 so that the shutter 45c does not collide with the turntable 24, according to the present embodiment, the shutter 45c is fully opened. Since the disk 43 passes above the turntable 24, the insertion height can be lowered to such an extent that the disk 43 does not contact the turntable 24, and the device can be made thinner accordingly.
Further, since the shutter 45c passes below the clamper 44 with the shutter 45c fully opened, the clamper 44 can be disposed below the upper surface of the shutter 45c, which is advantageous in reducing the thickness of the apparatus. Further, a support plate for supporting the shutter opening member as in the conventional apparatus is not required, and the apparatus can be made thinner accordingly.

After the disk cartridge 45 is mounted in the apparatus as described above,
When taking out, the operator presses the eject button 17 provided on the front bezel 16. As a result, the lock mechanism 13 moves the lock lever 1 disposed on the lower surface of the tray 12.
The lock 8 is released from the lock pin 19 provided on the main body side. When the lock of the tray 12 is released, the pressing lever 20 of the tray pressing mechanism 14 kicks the rear side wall 23 of the housing 22 by the spring force of the coil spring 21 and
In the direction A. Thereby, the operator can use the tray 12
Can be pulled out to the disk replacement position.

After the eject operation, the disc cartridge 45 passes through the turntable 24 as the tray 12 moves in the direction A, and then the shutter opening / closing mechanism 15 performs the reverse operation to close the shutter 45c. FIG. 12 is a plan view of a modification of the present invention, and FIG. 13 is a front view before a disk cartridge is inserted. 12 and 13, the same parts as those in the above embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

The disk device 70 has a slide member 71 which locks the disk cartridge 45 inserted in place of the tray and moves to the mounting position. The slide member 71 is formed to have substantially the same dimensions as the thickness of the disk cartridge 45, and a shutter opening arm 72 for opening the shutter 45c of the disk cartridge 45 is rotatably provided at an intermediate portion.

One end 72a of the shutter opening arm 72 is rotatably supported by a shaft 73 fitted to the support portion 71a of the slide member 71, and the other end 72b is engaged with the shutter 45c of the disk cartridge 45. Engaging pin 72c is provided. The shutter opening arm 72 is urged clockwise by a spring member (not shown). Therefore, before the disk is inserted, the shutter opening arm 72 has the engagement pin 72 c

Therefore, since the shutter opening arm 72 is provided so as to be accommodated in the upper and lower surfaces of the slide member 71, there is no need to form a space for supporting the shutter opening arm 72 above the disk cartridge 45, and The separation device has been made thinner.

Further, at both ends of the slide member 71,
A clamp member (hook member) 74 for hooking both sides of the disk cartridge 45 is attached. The clamp member 74 is rotatably supported by a shaft 75 implanted in the slide member 71, and has an engagement claw 74 a that engages with an engagement recess 45 e formed on both sides of the disk cartridge 45 at the end. Having. The engaging claw 74a of the clamp member 74 is rotationally urged inward by a spring member (not shown). Before the disk cartridge 45 is inserted, the engaging claw 74a slides on a pin 76 rising from the base 22b and moves outward. It is turning.

When the disc cartridge 45 is inserted into the apparatus, the end of the disc cartridge 45 contacts the slide member 71 to move the slide member 71 in the direction B. Since it is spaced apart from 76, the engaging claws 74a are fitted into the engaging concave portions 45e provided on both sides of the disc cartridge 45 by the spring force. As a result, the disk cartridge 45 is clamped by the clamp member 74 and can move in the B direction together with the slide member 71.

The slide member 71 is driven in the directions A and B by the drive mechanism 77 to move the disk cartridge 45 to the mounting position or the disk replacement position. The drive mechanism 77 includes a motor 78 provided on the base 22b, a lead screw 80 that is rotationally driven via a worm gear 79, and a pair of guides that engage with both ends of the slide member 71 to guide the movement of the slide member 71. It comprises a rail 81.

The slide member 71 includes a lead screw 8
When the lead screw 80 is rotationally driven by the motor 78, the lead screw 80 slides in the A direction or the B direction while being guided by the pair of guide rails 81 according to the rotation direction of the lead screw 80. The housing 22
When the slide member 71 moves in the direction A, a stopper 22c that regulates the movement position protrudes from the inner surface of the side wall.

Here, the operation of the modified example configured as described above will be described. 14 is a plan view showing a state where the disk cartridge is inserted, FIG. 15 is a plan view showing a state where the disk cartridge is mounted, and FIG. 16 is a front view showing a state where the disk cartridge is mounted.

When the disc cartridge 45 is inserted into the apparatus, first, the shutter 45c is engaged with the engaging pin 72c of the shutter opening arm 72. Then, while the disk cartridge 45 is being inserted in the direction B, the shutter opening arm 72 rotates counterclockwise to open the shutter 45c. Thereafter, the disc cartridge 45 contacts the slide member 71 with the shutter 45c opened.

When the disc cartridge 45 is pressed and the slide member 71 is moved in the direction B,
The engaging claw 74a of the clamp member 74 is separated from the pin 76 and fitted into the engaging recess 45e provided on both sides of the disc cartridge 45, and the motor switch (not shown) is turned on.

Thus, the motor 78 is rotationally driven, and the rotational driving force of the motor 78 is transmitted to the lead screw 80 via the worm gear 79. Therefore, the slide member 71 moves in the B direction according to the amount of rotation of the lead screw 80. Along with the movement of the slide member 71, the disk cartridge 45 clamped on both sides by the clamp members 74 is drawn into the apparatus.

When the disk cartridge 45 reaches a predetermined mounting position, the motor 78 is stopped, and the traverse 27 rotates upward. Thus, the traverse 27
Is turned upward, the turntable 24 mounted on the traverse 27 lifts the disk 43 of the disk cartridge 45 and clamps it to the clamper 44 provided on the top plate 22 a of the housing 22.
