Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc take-out tool suitable for taking out a disc contained in a disc holder.

[0002]

2. Description of the Related Art Generally, a disc such as a compact disc is housed in a disc holder in order to protect it from external damage and dirt during storage. In general, a disc-shaped disc has a ring-shaped non-recording area having a predetermined width around the center hole, and a recording area sequentially arranged outside the ring-shaped non-recording area. The disk holder is generally made of a plastic material, and is composed of a rectangular main body and a normally transparent opening / closing lid hinged to the main body, and the central portion of the main body has a stepped circular portion and a large number of inverted L-shaped elastic pieces. They are arranged side by side in a ring shape to form a disc locking portion. The center hole of the disc is fitted into the disc locking portion so that the disc is stably locked and accommodated in the disc holder by the spring action of the elastic piece.

In order to take out a disc from such a disc holder, the disc locking portion is pressed with a finger from above to release the locking, and the other two fingers are used to grasp both ends of the disc. It is common practice to lift it up and remove it from the disc holder. However, such an extraction method has a problem that the recording surface of the disk surface may be erroneously touched with a fingertip to transfer dirt. In addition, there is a possibility that the disc may be deformed by giving an excessive bending stress when it is taken out. Therefore, various disk ejecting devices have been proposed to solve this problem.

For example, in the device proposed by Japanese Utility Model Laid-Open No. 62-175462 (and its microfilm copy), a holder and a gripping portion are formed in a T shape, and a pair of suction cups are provided at both ends of the holder. Further, a pressing member biased downward by a spring and movable up and down is provided in the center of the holder. The inside of each suction cup communicates with the atmosphere through the communication passage of the holder.The communication passage is connected to the operation part provided on the upper part of the holder through the lever and is constantly lowered by the spring. It is designed to be opened and closed by a valve element that is biased to. To take out the disc from the disc holder using this device, hold the grip and press the operation part provided on the top of the holder to open the valve body, and make sure that each suction cup is in communication with the atmosphere. It contacts the recording area (more precisely, the upper surface opposite to the lower recording surface in the recording area, that is, the display surface), and the locking part of the disk holder is pressed from above by the pressing member to unlock the disk. Then lift it.

[0005]

However, the device proposed above has a problem that the structure is complicated, its outer shape and weight are large, and the cost is high. Also, since the recording area is pressed from above by the suction cup when the disc is taken out, if an excessive operating force is applied, the recording surface may be temporarily deformed or the recording surface and the disc holder surface may come into contact with each other. However, if it is repeated, it may affect the reproduction of the disc. Further, since the horizontal distance from the pressing portion to the suction cup becomes large, it is difficult to uniformly and accurately press the suction cups onto the disc, which may cause the disc to be nonuniformly adsorbed and dropped. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a simple and efficient disc take-out tool which solves the problems of the conventional disc take-out device.

[0006]

That is, the disc take-out tool of the present invention has a pressing body that presses the disc locking portion of the disc holder and a suction cup that abuts the non-recording area in the central portion of the disc, integrated with the bottom portion. A main body made of an elastic body formed in the above, and a grip portion provided on the upper portion of the main body. The sucker is characterized by being communicated with an opening opening on the surface of the grip portion by a communication hole.
In a preferred embodiment of the present invention, the suction cup is an annular suction cup arranged so as to make a round around the pressing body. In another preferred embodiment, the grip portion is configured to have a constricted portion in the middle thereof.

[0007]

According to the disc take-out tool of the present invention constructed as described above, the pressing body is brought into contact with the disc locking portion of the disc holder from above, and the non-recording is arranged around the center hole of the disc. When the area is brought into contact with the suction cup from above and the main body is pressed against the disc as it is from the top by the gripping portion, the locking portion of the disc is released by the pressing body and the suction cup is deformed to the non-recording area of the disc, as shown in FIG. When the opening of the communication hole is closed, it is adsorbed. Then, the disc can be taken out with one touch by holding the grip and lifting the main body. Further, when the disc is returned to the disc holder, the operation is performed in reverse, and the communication hole 17 is opened as shown in FIG. 7, so that the disc take-out tool can be separated from the disc surface.

According to the disk ejector of the present invention, the pressing body and the suction cup are integrally formed with the main body made of an elastic body, and the elasticity is utilized to perform an effective pressing action and adsorption action. It is not necessary to mount a spring on the pressing body or mount a valve body or a spring on the suction cup, unlike the device of (1). Therefore, the disk ejector is simple and lightweight. Further, since the suction cup is adapted to adsorb the non-recording area around the center hole of the disc, the pressing body and the suction cup are arranged close to each other. Therefore, the outer shape of the disk ejector can be made extremely compact. Further, there is no possibility of damaging the recording area of the disc during the suction operation, and the suction ability of the suction cup becomes uniform.

[0009]

Embodiments of the present invention will now be described with reference to the drawings.

Such an annular suction cup 14 is compact in a particularly small space and can obtain a relatively strong suction force. At the same time, it has the advantage of being easy to mass-produce. A plurality of suction cups may be arranged around the pressing body 13 instead of the annular suction cup 14.

In order to obtain good take-out operability, the grip portion 12 preferably has a constricted portion 15 in the middle and an enlarged portion 16 on the upper portion. For example, as shown in the figure, the upper portion is a part of an enlarged flat sphere, and the portion that is connected to the main body 11 is a rod-shaped body having a smaller radius than the sphere.
With such a shape, for example, a finger can be placed on the enlarged portion 16 to close the opening of the communication hole communicating with the suction cup, and the disc can be easily taken out. Grip 1
It is preferable that 2 is integrally formed with the main body 11 as shown in the figure, and that it is made of an elastic body. However, the present invention is not limited to this, and for example, the grip portion 12 made of a hard plastic material separately from the main body 11 can be joined to the main body 11 by adhesion or screw connection.

An opening 17 is provided on the surface of the enlarged portion 16 of the grip portion 12. Then, the opening 17 and the opening 18 formed on the inner surface of the suction cup 14 are communicated with each other through the communication hole 19, which is in the grip portion 12 and the main body 1.
Penetrate through 1. The opening 17 can be provided on the upper surface or the side surface of the enlarged portion 16 at a position where it is easy to operate. When a plurality of suction cups are formed around the pressing body 13 without forming the suction cups 14 in an annular shape, the openings 1 are formed in the respective suction cups 14.
8 are provided, and these and the opening 17 are communicated with each other through a communication hole 19.

Next, the operation of the disk ejecting tool 10 will be described. As shown in FIG. 6, the grip portion 12 is supported by two fingers, and the opening of the communication hole is closed by another finger.

In this example, the communication hole 19 is formed in a straight line in the main body 11 and the grip portion 12 so as to connect the shortest distance, and therefore a ridge 20 is formed on a part of the outer periphery of the grip portion. This is the same as the embodiment of FIG. The same parts as those in FIG. 1 are designated by the same reference numerals. Forming the communication hole 19 as shown in FIG. 4 has an advantage of facilitating manufacturing by molding. In addition,
The operation of the disk ejecting tool 10 is similar to that shown in FIG. The disc ejecting tool 10 of the present invention has a ring-shaped non-recording area in the center of the disc, and is a compact disc if the disc is of a type in which the locking hole of the disc is locked in the locking portion of the disc holder. It can be applied to other discs. Examples of such discs include mini discs and laser discs.

Next, FIGS. 8 to 12 show a second embodiment of the present invention. In this embodiment, an air bleeding valve is press-fitted into the grip portion 12, and the valve 23 opens the upper end opening of the communication hole 19. Always closed. Then, when the disc is sucked and removed from the ejector, the valve 23 is pressed downward to open the upper end opening of the communication hole 19 to the atmosphere and guide air to the inside to attract the suction force of the suction cup 14. It is to be released. In this embodiment, as shown in FIGS. 8 and 11 and 12, the valve body 22 is formed in a double cylinder shape that is connected to each other at one end, and the inner cylinder part is formed in a stepped manner and the center thereof is formed. A valve insertion hole is formed in. A plurality of cutout portions 26 are provided at the hole edge portion, and the entire hole edge portion forms the valve seat portion 24.
