[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compact disk lifting device for slightly lifting a disk from a compact disk storage case by a spring mechanism.

[0002]

2. Description of the Related Art A CD case for accommodating a compact disk (hereinafter abbreviated as CD) has a circular hole 11 at the center as shown in plan and side sectional views in FIGS. 6A and 6B. Body 21 for storing CD 10 having
And a protrusion 21 formed in a cylindrical shape on the bottom surface of the case body 20 corresponding to the circular hole 11. The projecting portion 21 has elasticity capable of being deformed in the radial direction. When the projecting portion 21 is pressed into the circular hole 11 by lowering the CD 10, the CD 10 is firmly held in the case main body 20.

FIG. 6C is an enlarged sectional view showing the protrusion 21. The projecting portion 21 includes a plurality of projecting pieces 22.
Are arranged in an annular shape, and each protruding piece 22 is
A and a flat portion 22B extending inward in the horizontal direction from the tip of the upright portion 22A. The upright portion 22A is slightly inclined inward, and the diameter of the middle portion thereof matches the diameter of the circular hole 11 of the CD 10. Therefore, lower CD10,
When the protruding portion 21 is press-fitted into the circular hole 11, the upright portion 22A slightly deforms inward in the radial direction as shown by an arrow 23,
The CD 10 is firmly held around the protruding portion 21 by the reverse elasticity for restoring this deformation.

In order to remove the CD 10 from the case body 20, it is necessary to raise the CD 10 whose projection 21 is pressed into the circular hole 11, but the force required at this time is unexpectedly large, and it is difficult to grip the CD 10. There are drawbacks. What solves this problem is a CD lifting device called a CD push-up button.

FIG. 7 is an enlarged sectional view showing an example of a conventional CD raising device 30. As shown in FIG. The device 30 includes a push button 31 for pushing the flat portion 22B of the projecting portion 21, a spring (for example, a coil spring) 32 for raising the CD, and a spring 3
And a two-end CD contact body 33. Push button 31
The CD contact body 33 is a resin material. The push button 31 includes a pressing head 31A, a body 31B extending downward from the head 31A, and an engaging portion extending laterally from the lower end of the body 31B and engaging with the lower surface of the protruding portion 21. 31C. One end of the spring 32 is molded on the push button 31, and the other end is molded on the CD contact body 33.

[0006] With the CD lifting device 30 mounted on the projection 21 of the CD storage case, the CD 10 is lowered.
When the protrusion 21 is pressed into the circular hole 11 of the CD 10, the CD
The spring 32 of the lifting device 30 is deformed and held between the CD 10 and the case main body 20 in a state where the spring 32 is pushed in the direction of the arrow 34 by the CD 10 to store the elastic return force. This is C
The holding force of CD10 by D10 and protrusion 21 is
This is because it is superior to the elastic return force of No. 2.

To remove the CD 10, the head 31A of the push button 30 is pressed downward from above. In this manner, as shown by the arrow 23 in FIG.
Of the flat portion 22A is deformed inward, whereby the upright portion 22A is deformed radially inward. As a result, CD10
Press-fit state between the circular hole 11 and the protruding portion 21 is released, and the elastic return force of the spring 32 indicated by the arrow 35 wins, and the CD 10
Slightly rises due to the elasticity of the spring 32. The CD 10 raised by the elasticity of the spring 32 can no longer be elastically engaged with the protruding portion 21 and can be easily taken out.

[0008]

The C of the structure shown in FIG.
Since the D lifting device 30 is of a cantilever type in which the integral spring 32 protrudes to one side of the protruding portion 21, the CD 10 is necessarily tilted and raised. In addition, since the number of parts is three, parts management is complicated. In addition, since the shape of the push button 31 is complicated, a mold slide mechanism is required, and manufacturing is not simple. These are the problems to be solved by the present invention.
