Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compact disk simple ejector for taking out a compact disk in which information used in music, video, computer and other industries is recorded from a stored case. .

[0002]

2. Description of the Related Art Compact discs (hereinafter simply referred to as "C
D ". As a method of taking out the CD mounted on the mating tube inside the case, the upper surface of the mating tube fitted with the CD is pressed down with one finger so that the upper surface of the mating tube falls down and fits. The outer diameter of the cylinder is slightly reduced, so that the spring effect of pressing the center hole of the CD is lost, and the center hole of the CD is disengaged from the fitting cylinder. The CD is detached from the CD case by sandwiching and lifting the outer peripheral edge of the CD with a finger.

[0003]

In such a conventional method of removing a compact disk, when the fitting cylinder is pressed by one finger and the outer periphery of the compact disk is removed by another finger or by hand, the compact cylinder is removed. The information recording surface may be damaged by mistake, or the shape of each side of the upper surface of the fitting tube may be different when pressing the fitting tube, or the thickness of the finger may be different, so that the pressing method may be different. There were problems such as failure to go well and failure.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention provides a compact disk simple ejector which has a simple structure and is capable of uniformly and effectively instantaneously ejecting a CD by the action of an elliptical lift arm radius of curvature. It is intended to provide.

[0011]

[Form and name of each part of simple CD ejector] The simple CD ejector 1 has a cylindrical push base body 2, a pressing portion 3 formed on the top of the push base body 2, and a bottom ellipse of the push base body 2. The push base body 2, the pressing portion 3, and the elliptical lift are formed of a predetermined smoother reinforcing cylinder 6 and two elliptical lift arms 4 having a radius of curvature R on the pressing portion 3 side. The arm 4 is integrally formed of plastic or resin.
In addition, a smoother reinforcing cylinder 6 for facilitating insertion of the main body of the simple CD ejector, and a fall-off prevention portion 5 for preventing fall-off.
Is arranged.

In order to attach the simple CD removal tool 1 to the fitting cylinder 12 on which the CD 10 is mounted, the push base body 2 is adjusted by aligning the elliptical lift arm 4 with an arbitrary groove 13 formed in the fitting cylinder 12. Is fitted into the circular space portion 14 formed in the center of the fitting tube 12 to obtain a state as shown in FIG. At this time, it is preferable to push in such that the back surface of the pressing 3 is in close contact with the upper surface of the fitting tube 12.

A method of removing the CD 10 from the fitting tube 12 using the simple CD removal tool 1 will be described. As shown in FIG. 3, a state in which the pressing portion 3 is pressed downward with a finger to crush the fitting tube 12 is shown. When pressing is performed, the back surface of the pressing portion 3 is
4, the fitting tube 12 falls down and contracts in diameter to release the fitting between the outer periphery of the fitting tube 12 and the CD 10.

At the same time, as shown in FIG. 2B, the simple CD ejector moves downward by pressing, so that the elliptical lift arm 4 moves upward with the division groove 13 and the elliptical base point 23 as fulcrums, and the principle of medium movement. Lifts the CD 10. Therefore, the CD 10 can be inserted into the fitting cylinder 1 only by pressing the pressing portion 3 with a finger.
2 and protrudes to the upper part of the fitting tube 12, so that the CD 10 can be easily taken out only by holding the CD 10 between the floating fingers.

In this case, an intermediate portion of the elliptical lift arm 4 is supported by the elliptical base point 23 of the dividing groove 13 and the tip of the elliptical lift arm 4 is pressed to lift the back surface of the CD 10 by the movement of the elliptical base point 23. Since the back surface of the CD 10 is reliably lifted by simply pressing the portion 3 lightly, the CD 10 can be reliably lifted by simply pressing the pressing portion 3 lightly.

The division groove 13 formed in the fitting tube 12 has a width reduced at the inner edge of the circular space portion 14 and is arranged by the reinforcing cylinder 6 formed on the elliptical lift arm 4 and the radius of curvature R, so that an elliptical base portion 23 is formed. The drop-out prevention unit 5 prevents the simple CD removal tool 1 from falling off, thereby reducing the play in the vertical direction of the CD removal tool, and the fingertip adheres to the pressing unit 3 by sweat or the like to prevent the CD from being removed.
The simple removal tool 1 can be prevented from lifting together with the CD 10, and the strength when the elliptical lift arm 4 moves to the base point can be improved. Simple CD removal tool 1
Can be integrally molded by an injection molding machine or the like, so it has mass productivity, is inexpensive, and can be used for various types of CD cases such as CDMD, DVD, and the like.

[0017]

As described above, the simple CD ejector of the present invention is arranged so as to cover the upper surface of the fitting cylinder and the cylindrical simple CD ejector mounted in the circular space of the fitting cylinder. And an elliptical lift arm disposed inside the division groove of the fitting cylinder, wherein the CD simple ejector, the pressing portion, and the elliptical lift arm are integrally formed of plastic or resin. , So just press the pressing part lightly
Can be easily and reliably taken out. In addition, since the simple CD ejector is integrally molded, mass production is possible.

According to the second aspect, the stability of the elliptical lift arm 4 is effectively increased by the R of the connecting portion between the elliptical lift arm and the body of the push base, the dividing groove introduction portion 22 and the fall prevention 5, and the CD is simplified. While reducing the play of the removal tool 1,
It becomes difficult to separate from the CD case 11, and the strength of the elliptical lift arm 4 can be improved.
