The pull-in lever 27 in a state where the disk adapter 10 is not inserted is in a standby state in a state where it is rotated by a predetermined angle toward the spindle motor 23 side. In this state, the convex portion 28A of the sub lever 28 is located at the movable side end of the long groove 27C. Further, the distance between the guide 26 and the second disk guide 27 </ b> A is narrower than the diameter of the disk adapter 10.
In the initial stage when the disk adapter 10 is inserted, the disk adapter 10 firstly has the fourth contact surface 17D in contact with the guide 26 and the first contact surface 17A in contact with the second disk guide 27A. 26 and the second disk guide 27A are supported and regulated.
When the disk adapter 10 is further pushed in, the second disk guide 27A swings in the direction away from the spindle motor 23 along the first contact surface 17A. As the second disk guide 27A pivots, the convex portion 28A of the sub lever 28 slides in the long groove 27C toward the fixed side end. Therefore, the sub lever 28 also turns around the rotation fulcrum 28B. When the insertion operation of the disk adapter 10 is further continued, the third contact surface 17C of the disk adapter 10 contacts the guide 29A of the discharge lever 29. FIG. 6 illustrates this state.
In the state shown in FIG. 6, the loading motor 60 does not operate, and therefore the main slider 40 and the sub lever 50 do not operate.

FIG. 7 is a plan view of the base body of the disk device showing a stage during disk insertion.
When the disk adapter 10 is further inserted from the state shown in FIG. 6, the fifth contact surface 17 </ b> E of the disk adapter 10 is supported by the guide 26. The pull-in lever 27 is in the state farthest from the spindle motor 23. In this state, the convex portion 28A of the sub lever 28 is located at the fixed side end of the long groove 27C. On the other hand, since the guide 29A is pushed by the third contact surface 17C of the disk adapter 10, the discharge lever 29 continues to rotate with the insertion operation of the disk adapter 10.

When the disk adapter 10 is further pushed in from the state shown in FIG. 7, the second disk guide 27 </ b> A moves along the first contact surface 17 </ b> A in the direction close to the spindle motor 23 in this insertion operation. As the second disc guide 27A pivots, the projection 28A of the sub lever 28 slides in the long groove 27C from the fixed side end toward the movable side end. Therefore, the sub lever 28 also turns around the rotation fulcrum 28B.
On the other hand, in the above-described operation process, the second abutting surface 17B of the disk adapter 10 abuts on the guide 30B of the regulating lever 30, and the regulating lever 30 rotates.
When the second disk guide 27A is rotated by a predetermined angle in the direction approaching the spindle motor 23, the regulating lever 30 is also rotated by a predetermined angle by the second contact surface 17B of the disk adapter 10. Then, when the regulating lever 30 rotates by a predetermined angle, the limit switch operates and the driving of the loading motor 60 is started. Note that the guide 182 of the guide lever 180 is in a state of protruding toward the disk adapter 10, and the disk adapter 10 is supported by the guide 182 and slides.
By driving the loading motor 60, the main slider 40 starts to slide toward the rear surface side. Then, by the operation of the main slider 40, the pin 28C of the sub lever 28 moves along the cam groove provided in the corresponding main slider 40. At this time, the pin 28C moves to the spindle motor 23 side by the corresponding cam groove. By the movement of the pin 28C, the sub lever 28 urges the pull-in lever 27 in a direction in which the movable side end turns to the spindle motor 23 side. Accordingly, the pull-in lever 27 urges the disk adapter 10 in the insertion direction. Due to the urging force of the pull-in lever 27, the disk adapter 10 is released from the artificial operation and further pushed.

FIG. 8 is a plan view of the base body of the disk device showing the completion of the disk adapter insertion.
The disk adapter 10 is supported at three points: the second disk guide 27A, the guide 182 of the guide lever 180, and the guide 30B of the restriction lever 30, and the center hole of the disk A is restricted to a position corresponding to the spindle motor 23. . In this state, the guide 30B of the regulating lever 30 is engaged with the second displacement portion 15B.
On the other hand, the loading motor 60 continues to be driven and the main slider 40 continues to slide.
The main slider 40 moves for a predetermined time from the state shown in FIG. 8, but the sub lever 28 does not operate because the cam groove corresponding to the pin 28C of the sub lever 28 is formed in parallel with the moving direction. In this state, the convex portion 28A of the sub lever 28 is positioned in the groove 27C. The pull-in lever 27 does not operate, and the state where the disk adapter 10 is supported is continued.
On the other hand, the cam lever 70 still does not operate for a predetermined time from the state shown in FIG. That is, cam grooves corresponding to the pins 72 and 73 of the cam lever 70 are formed in parallel with the moving direction of the main slider 40.

FIG. 9 is a plan view of the base body of the disk device showing the stage after the predetermined time has elapsed from the state shown in FIG.
