The operation of the disk drive of the present invention having the above configuration will be described with reference to FIGS. First, the operation when the disc 10 is inserted will be described. In the disk device before the disk 10 is supplied, as shown in FIG. 2A, the first slide member 210 is located at the forefront, the second slide member 310 is located at the farthest position, and the first rocking body 250 is 2
As shown in (b), the pin 250s urged in the direction of the arrow 250A abuts against the cam groove 210s provided on the upper surface of the first slide member 210 and stops. It is urged in the direction of arrow 350A and stopped at the position shown in FIG.
At this time, the pin 350s is at a position away from the cam groove 310s provided on the upper surface of the second slide member 310 as shown in FIG. In this state, the disk 10 supplied by the operator first contacts the pin 250d provided at the tip of the first rocking body 250 at the position 10R.

Next, when the operator further inserts the disc 10 into the back, the disc 10 is inserted into the pins 250d at the tip of the first swinging body 250, the left and right guides 720 and 730, and the middle of the tip of the second swinging body 350 from the middle. It reaches the position shown in FIG. 3A while the height direction and the left and right positions are regulated by the pin 350d. At this time, the first rocking member 250 is pushed by the pin 250d at the tip of the disk 10 and rotates in the direction of the arrow 250B, and the pin 250s moves in the cam groove 210s to the position shown in FIG. Also, the second oscillator 35
0 also pushes the pin 350d at the tip by the disk 10 to rotate in the direction of the arrow 350B, and the pin 350s rotates to the entrance position of the cam groove 310s as shown in FIG. Also, as shown in FIG. 3A, the switch lever 370 rotates in the direction of the arrow 370A with one end 370e being pushed by a part 350e of the second rocking body 350, and the pin 370u pushes the detection switch 813.

When the detection switch 813 is pressed, the driving means 281 starts, and the movement of the first slide member 210 in the direction of the arrow 10A is started. In conjunction with this, the second slide member 310 also moves the arrow 10B. Start moving in the direction. Then, as shown in FIG. 4B, the first oscillator 2
The 50 pin 250s is driven by the cam groove 210s that moves in the direction of the arrow 10A and moves to the position shown in the drawing.
4A is an arrow 250A as shown in FIG.
Rotate in the direction. As a result, the pin 250d at the tip of the first rocking body 250 transports the disk 10 in the direction of arrow 10A until it comes into contact with the pins 511a and 511b of the disk positioning member 510.

At this time, the pin 350s of the second rocking body 350
Is driven by the cam groove 310s moving in the direction of the arrow 10B as shown in FIG.
As shown in FIG. 4A, the second rocking body 350 has an arrow 35

After moving in the direction of 50B and the disk 10 abutting the pins 511a and 511b of the disk positioning member 510, the disk 10 rotates to a position slightly away from the disk 10.
In the state of FIG. 4, the center hole 10a of the disk 10 is aligned with the center of the hub 110a of the spindle motor 110.

The operation of transporting the disk 10 from FIG. 3 to FIG. 4 is called a disk pull-in operation. Further, since the direction of the acting force of the reversing spring 356 is reversed during the retraction operation, the second sliding member 350 is rotated at a large angle in the direction of the arrow 350B.
The load applied to the first swinging member 250 in the pulling-in operation is slight, and the first swinging member 250 rotates in the original biasing direction by the first slide member 210.
Since the direction is the same as that in the 50A direction, the load on the driving means 281 in the pull-in operation becomes small. Furthermore, at this time, the first rocking body 250 and the second rocking body 350 are located outside the projected area of the base body 100, and do not hinder the subsequent rise of the base body 100.

Next, the raising operation of the base body 100 and the accompanying holding operation of the disk 10 by the spindle motor 110 will be described. Although the first slide member 210 and the second slide member 310 continue to move further, FIG.
As shown in FIG. 4B and FIG. 4C, both the pin 250s and the pin 350s are located in the straight portions of the cam grooves 210s and 310s, so that the first slide member 210 and the second slide member 310 The first oscillating body 250 is also moved to the second oscillating body 350 until the pin 250 s is at the position of 250 s ′ and the pin 350 s is at the position of 350 s ′.
Also, the rotation is stopped in the state of FIG.

On the other hand, as shown in FIG. 5, the base chassis 130 has a pin 132a provided on the side surface during the movement of the first slide member 210 in the direction of the arrow 10A until the state shown in FIG. Since the slide member 210 is positioned at the straight portion of the cam groove 210a, it is stopped in a lowered state. However, the first slide member 210 further moves until the pin 250s in FIG. 4B comes to the position of 250s'. In the meantime, FIG.
From the state shown in FIG. 5A to the state shown in FIG.
Pushes up the pin 132a, and the hub 110a of the spindle motor 110 on the base chassis 130
And the spindle motor 110 rises, and the disk 10 is sandwiched between the convex portion 90s provided on the ceiling of the frame 90 and the turntable surface 110b of the spindle motor 110.

However, as shown in FIG.
b has only a bottom surface, the pin 132b, which is the fourth point, may rise from the first cam groove 210b when the base body 100 is deformed. When the recording / reproducing position shown in c) is reached, the leaf spring portion 285a elongated from the driving means support body 285 pushes the base chassis 130 downward so that the lower end of the pin 132b follows the bottom surface of the cam groove 210b. , Lifting is prevented, and the base body 100
Can maintain level.

The operation of the first slide member 210 from FIG. 5 (b) to FIG. 5 (c) causes the pin 250s of the first rocking body 250 to move into the cam groove 210s as shown in FIG. 6 (a).
As a result, the pin 250d at the tip of the first rocking body 250 is separated from the disk 10 by rotation in the direction of the arrow 250B, and the bent portion 410b of the slide connection member 410 is rotated by the rotation of the slide connection member 410 in the direction of the arrow 410A.
