Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a disc insertion device for a disc player such as a video disc player or a compact disc player, and particularly to a disc insertion device for a disc player that uses a slot-in method. Regarding.

[Background of the idea]

2. Description of the Related Art In recent years, attention has been paid to the so-called slot-in method in which, when a disc, such as a compact disc, on which information is recorded is inserted into a disc player, the disc is directly inserted into the player from the outside. A disk player that adopts such a slot-in method has a horizontally elongated insertion opening in the front of the case that houses the player's mechanism body, and the disk is directly inserted into the case through this insertion opening, and the inserted The disc is mounted on the disc holding surface of the holder provided in the case, which simplifies the mounting of the disc, improves operability, and makes the player more compact. It has the advantage of

However, in the past, when such a slot-in method was adopted, there was a risk that the disk surface would be damaged by the disk holding surface of the holder during insertion. That is, as shown in FIG. 1, when inserting the disk 1 into the case 2 by pushing it in the direction of arrow A, the disk 1 that has passed through the vertical center of the insertion opening 3 remains directly on the disk holding surface of the holder 4. At this time, if the disk 1 and the disk holding surface 4a are kept in surface contact with each other, the lower surface of the disk 1 may be damaged. This is disk 1 when inserted.
This is due to the positional relationship between the holder 4 and the
In order to prevent the disk surface from being rubbed against the wall surface of the insertion opening 3, the disk 1 needs to be inserted approximately at the vertical center of the insertion opening 3. The location is also
The height is set so that such a disk can be easily inserted.

It is known that if the disc surface is damaged, the playback function of the disc may be adversely affected. For example, in the case of a compact disk,
Although the recording surface is protected by transparent plastic, if this plastic surface gets scratched, it may interfere with music playback.

[Purpose of invention]

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and its purpose is to provide a disk insertion device for a disk player that does not cause damage to the disk surface during insertion.

[Summary of the idea]

In order to achieve this purpose, the present invention provides a rotatable structure that is placed near the insertion opening inside the case housing the mechanism body and that comes into contact with the lower surface of the disk during insertion and guides the disk toward the holder. A roller is provided, and the disk holding surface of the holder is positioned below the top of the outer peripheral surface of the roller.

[Example of idea]

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

FIG. 2 is a partially sectional plan view showing an embodiment of the present invention, FIG. 3 is a side sectional view thereof, and FIG. 4 is an enlarged view of the main part of FIG. 2 is a case housing a mechanism main body (not shown); 3 is a horizontally elongated insertion slot provided on the front surface of the case 2; and 4 is a case provided inside the case 2 to hold the disk holding surface 4a. Holders 5 and 6 are respectively a roller and a presser roller that are rotatably supported near the insertion opening 3 inside the case 2, and these rollers 5 and 6 are
For example, it is constructed by covering the peripheral surface of a metal shaft with rubber, soft plastic, fiber, or the like. In addition, virtual lines B and C in FIG. 2 are, respectively,
It shows the position of the disk during insertion and at the end of insertion.

The roller 5 and the presser roller 6 serve to sandwich the disk inserted through the insertion opening 3 and guide it toward the holder 4.
The disk inserted into the case 2 in this manner is mounted on and held on the disk holding surface 4a of the holder 4. As shown in FIG. 4, the disk holding surface 4a of the holder 4 is positioned below by a dimension D with respect to the top of the outer circumferential surface of the roller 5 that contacts the lower surface of the disk.

Now, when the disk 1 is inserted from the outside into the insertion slot 3, the leading end of the disk 1 is first held between the roller 5 and the presser roller 6, and then the disk 1 is Since the tip of the disk 1 is lowered by its own weight, when the tip is lowered by the dimension D, the outer edge corner of the disk 1 comes into contact with the disk holding surface 4a of the holder 4, as shown in FIG. The disk 1 that is further pushed in from this state is guided into the case 2 while sliding on the disk holding surface 4a as the rollers 5 and presser rollers 6 rotate, and is guided to the position indicated by the imaginary line B in FIG. reach.

At this time, disk 1, which is tilted forward and downward,
Since sliding is performed with only the outer edge corner portion contacting the disk holding surface 4a, the lower surface of the disk 1 is not damaged by this sliding. Further, when passing through the insertion opening 3, the disk 1 is positioned approximately at the vertical center of the insertion opening 3 by being held between the roller 5 and the presser roller 6, and is guided into the case 2 in this state. Therefore, there is no risk that the disk surface will be rubbed against the wall surface of the insertion slot 3.

By providing an appropriate loading mechanism inside the case 2, the disk 1 inserted up to the position of the imaginary line B in FIG.
It is possible to complete the loading by moving it to the position shown in FIG.
Such loading mechanisms include, for example,
A possible mechanism is a combination of a worm, gears, etc. with a motor capable of forward and reverse rotation, and a means for pressing the outer edge of the disk.

[Effect of idea]

As explained above, according to the present invention, since the outer edge corner of the disk slides on the disk holding surface of the holder during insertion, there is no risk of damaging the bottom surface of the disk with the disk holding surface, and moreover, the roller Since the disk position is set and guided, there is no risk of the disk surface being damaged by the wall surface of the insertion slot during insertion.
