Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a compact disc ejector, and more particularly to a compact disc ejector used to take out a compact disc from a case.

BACKGROUND ART As shown in FIGS. 6 and 1, a compact disk 1 is clamped by fitting a central hole 1a into a clamper 2 having elastic pieces arranged in the shape of petals, and placed on a tray 3. It is housed in a case 4 with a rotating lid.

To take out this disk 1 from case 4,
It is necessary to do this without touching the recording surface with your fingers; for example, straddle Disc 1 with the fingers of one hand and press Disc 1.
At the same time, the user presses the clamper 2 with the fingers of the other hand to release the clamp, and then takes it out from the case 4.

Problems that the invention aims to solve: For this reason, it is difficult for people with small hands to take out the disc, and even people with normal-sized hands can accidentally record the disc's signal when taking it out. There were problems such as the surface being damaged.

Means for Solving the Problems The compact disk ejector of the present invention has a push rod support in the center, a body around the periphery, and an air chamber between them with an opening at the bottom, and the bottom faces the opening. It consists of a rubber body having a tongue and a ventilation hole communicating with the air chamber at a predetermined position, and a push rod for releasing the clamp provided at the push rod support part of the main body, the center of which is By fitting the hole into the clamper and placing it on the top surface of the compact disk stored in the case, pressing the body to reduce the air chamber, closing the ventilation hole, and releasing the pressure. , the air chamber becomes negative pressure due to the restoring force of the body itself, thereby adsorbing the compact disk to the main body, and pushing down the push rod to push the clamper;
The compact disk is configured to be unclamped.

Function The disk suction force is obtained by the restoring force of the body itself, and no special member is required to obtain the suction force, and the structure is simple.

Embodiment FIG. 1 shows a compact disc ejector 10 which is an embodiment of the present invention.

This disk ejector 10 has a main body 11 generally made of resilient rubber or soft synthetic resin.
and a push rod 12 for releasing the clamp.

The main body 11 has a substantially bell shape, and has a cylindrical push rod support part 13 in the center and an annular air chamber 15 around the push rod support part 13 with an opening 14 at the bottom.

The air chamber 15 is formed by the push rod support part 13 and a body part 16 which is an outer peripheral wall. The opening 14
is annular, and annular tongues 17 and 18 extending from the push rod support portion 13 face here.
Further, the ring of the opening 14 is made somewhat larger than the central hole 1a of the disk 1.

Concave finger rests 19 and 20 are formed on both upper sides of the body 16 in the radial direction. Each finger rest 19,
At the bottom of 20, there is a ventilation hole 2 that communicates with the air chamber 15.
1 and 22 are formed.

The push rod 12 is fitted into a sleeve 23 which is fitted and fixed within the support portion 13 so as to be slidable up and down.

This push rod 12 is moved by the arrow A by the return spring 24.
The substantially spherical contact 25 attached to the lower end is recessed inside the main body 11.

A cap 26 is made of the same material as the main body 11, is fixed to the upper part of the main body 2, and constitutes a head portion.

Next, an example of the operation and operation when taking out a disk from the case using the disk ejector 10 having the above structure will be described with reference to FIGS. 2 and 3.

In addition, as shown in FIG.
0 with the middle finger 31 placed on the disc 1, align the center of the disc 1, and place the tongues 17 and 18 on the upper surface 1b of the disc 1 so as to abut the area around the center hole 1a.

Next, as shown in FIG. 2, the body 16 is firmly pinched between the thumb 30 and middle finger 31 toward the center. As a result, the body 16 is elastically deformed, the air chamber 15 is contracted, and the air in the air chamber 15 is transferred from the opening 14 to the tongue 1.
7, 18 and is pushed out.

Next, push the top of the cap 26 in the direction of arrow B with your index finger 32 or your palm. As a result, the push rod 12 moves downward in the direction of arrow B against the spring 24, and the contact 2
5 pushes clamper 2, which bends and releases disk 1.
clamp is released.

Next, while keeping the ventilation holes 21 and 22 closed, the pinching force between the thumb 30 and middle finger 31 is slightly loosened. As a result, the body 16 tries to restore itself by its own restoring force, the air chamber 15 becomes negative pressure, and the disk 1
is attracted to the main body 11.

When the disk ejector 10 is pulled up in this state, the central hole 1a is easily removed from the clamper 2, as shown in FIG. 3, and the disk 1 is reliably removed from the case 4 while being attracted to the main body 11.

After taking out the disk 1 from the case 4, the pressing by the index finger 32 is released. As a result, the push rod 12 is returned upward by the spring 24.

To place the disc 1 on the tray of the player, hold the disc 1 on the tray, place it on the tray at a predetermined position, and separate the thumb 30 and middle finger 31 from the ventilation holes 21 and 22. As a result, the air chamber 15 communicates with the outside through the ventilation holes 21 and 22, the pressure inside the air chamber 15 becomes atmospheric pressure, the suction of the disk 1 is released, and the disk 1 is removed from the main body 11 and placed on the tray. be done.

The disk ejector 10 is removed alone from above the tray.

The operation of taking out the disk 1 from the player and returning it to the original case 4 is to do nothing but push down the push rod 12 when taking it out from the tray, and push down the push rod 12 when returning it to the case 4 to release the clamper 2. , is performed in the same way as above.

The disk 1 is housed in the case 4 with the recording surface facing downward, and since the upper surface 1b is not the recording surface, there is no problem even if the main body 11 comes into contact with the upper surface 1b.

FIGS. 4 and 5 show compact disc ejectors 40 and 50, respectively, which are other embodiments of the present invention. In each figure, parts that substantially correspond to those shown in FIG. 1 are designated by the same reference numerals, and their explanations will be omitted.

The disk ejector 40 shown in FIG. 4 is made by extending the upper part of the main body upward and integrally molding a head portion corresponding to the cap 26 of the disk ejector 10, and the main body 41 has a main body 41A and a head. It consists of part 41B. The clamp release push rod 42 is shorter than the push rod 12 described above, and has a support portion 43.
It is attached to.

When the head portion 41B of the main body 41 is pushed downward, the head portion 41B and the main body portion 41A are elastically deformed, the push rod 42 moves downward, and the clamper 2 is pushed in the same manner as described above.

This disk ejector 40 has fewer parts and is less expensive than the disk ejector described above.

The disk ejector 50 shown in FIG.
The push rod 52 for releasing the clamp is configured as follows.
is attached to the support portion 53, and the head portion 51 is attached to the support portion 53.
A ventilation hole 54 communicating with the air chamber 15 is provided at the top of B.

In addition to the effects of the disk ejector 40 described above, this disk ejector 50 is easy to use because it is only necessary to release the index finger blocking the ventilation hole 54 when setting the disk on the tray, and there is no need to change the grip.

Effects of the invention As mentioned above, according to the compact disc ejector of the present invention, anyone can easily take out a compact disc from a case, which was difficult in the past, and also remove the recording surface. It can be done safely and reliably without the risk of damage, and since the adsorption force of the compact disk is obtained from the elastic restoring force of the main body itself,
It has the features of simple structure, low cost, and high popularity.
