## Abstract

A lift frame supports a turntable unit, and moves between a lower-most position and a read/write position in conjunction with slide movement of a follower slider. The follower slider has a pressing member and a cam groove. Pressed to a bottom plate of a device chassis by a coil spring, the pressing member stabilizes the movement of the follower slider. The cam groove fits onto a lifting pin of the lift frame. At the read/write position, the cam bottom wall is constituted of a pin pushing portion. The pin pushing portion is pushed upward by the coil spring to press the lifting pin to a cam groove upper wall when the lift frame is in the read/write position.

## Claims

### Claim 1

A disk device including a slider configured to slide on a surface, and a lift frame configured to support a turntable to hold and rotate a disk, said lift frame having a lifting pin fit into a cam groove provided on the slider and said lift frame being lifted from a lower-most position in conjuction with slide movement of said slider, so as to attach said disk to said turntable, and then being put in a read/write position, said disk device comprising:
a pressing member provided on said slider;
a resilient pin pushing portion constituting a cam wall of said groove in the area where said lift frame is put in said read/write position; and
a spring, located between said resilient pin pushing portion and said resilient pin pushing portion to press said lifting pin to an opposite cam wall of said cam groove.

### Claim 2 (depends on 1)

The disk device of claim 1, wherein said surface is a bottom plate surface of a device chassis.

### Claim 3 (depends on 1)

The disk device of claim 1, wherein said pressing member is rotatably attached to said slider.

### Claim 4 (depends on 3)

The disk device of claim 3, wherein said pressing member has a plate-like shape with a shaft hole, which ratably fits onto a shaft formed on said slider.

### Claim 5 (depends on 1)

The disk device of claim 1, wherein said pressing member is integrated with said slider.

### Claim 6 (depends on 5)

The disk device of claim 5, wherein said pressing member is a projection having an L-shaped cross section.

### Claim 7 (depends on 1)

The device of claim 1, wherein said pressing member is attached to said slider and movable up and down with respect to said slider.

### Claim 8 (depends on 7)

The disk device of claim 7, wherein said pressing member includes a columnar portion and a retaining flange on said columnar portion, and said columnar portion projecting from an opening on a bottom of said slider.
