BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a tray door of a disc player, and more particularly to a tray door of a disc player suitable for preventing the tray door from being opened when the tray is housed inside the disc player. Regarding the structure.

[0002]

2. Description of the Related Art Conventionally, as a structure of a tray door of a disk player formed separately from a tray, many of those having a side sectional view shown in FIGS. 3 and 4 have been provided. FIG. 3 is a side sectional view showing a state in which the tray is housed inside the disk player, and FIG. 4 is a side sectional view when the tray moves down to bring the disk into a reproducing state.

In FIG. 1, reference numeral 1 denotes a panel of a disc player, 10 denotes a tray door, and the tray door 10 has a projection 10a formed in a substantially crank shape. Reference numeral 11 denotes a tray. The tray 11 is stored on a tray seat plate 12 of a disk drive mechanism (not shown).

Reference numeral 4 denotes a spring mounted on the tray door 10, and the spring 4 urges the tray door 10 to close. 5,6
Is a gear mechanism for braking the opening / closing operation of the tray door 10;
Is a large gear formed on the tray door 10, and 6 is a small gear formed on the main body.

[0005] The structure of the tray door 10 of the disc player thus configured is such that when the tray 11 is mounted, the tray door 10 is opened and the tray 11 storing the disc is inserted into a predetermined position. The tray 11 is placed on the seat plate 12 and housed inside the disc player, and the tray 11 is driven downward by the disc driving mechanism to be mounted at the disc reproduction fixed position shown in FIG.

When the tray 11 is mounted at the fixed reproduction position, even if the tray door 10 is to be opened, the protrusion 10
a contacted the tray 11 to prevent the tray door 10 from being opened.

[0007]

However, the above-described structure of the conventional tray door 10 of the disc player is such that the tray 11 housed in the main body moves down, and the tray 11 is mounted at a fixed reproduction position. In order to prevent the opening operation of the tray 10, the disc player in which the tray 11 does not move up and down at the time of mounting cannot prevent the opening operation of the tray door 10.

As a recent tendency of the disc player, the tray 11 mounted inside the main body is moved up and down by the driving mechanism, so that it takes time during reproduction and the vertical movement of the tray 11 is eliminated because the reliability of the mechanism is reduced. The playback drive has been started at the insertion position of the tray 11.

As described above, the disc player in which the tray 11 does not move up and down has a drawback that the tray door 10 can be arbitrarily opened even after the tray 11 is mounted.

The present invention has been made in view of the above points, and aims at solving the drawbacks of the conventional example, and opening the tray door after mounting the tray in a disc player which does not move up and down. An object of the present invention is to provide a structure of a disc player tray door for blocking.

[0011]

The structure of the tray door of the disc player according to the present invention includes a tray door formed separately from the tray of the disc player, a spring biased to close the tray door, and the tray door. The structure of a tray door of a disc player having a gear mechanism for braking the opening and closing operations of the disc player, comprising: a locking portion provided on the back surface of the tray door; and a projection provided on a lower portion of the tray. When the tray door is opened with the tray housed therein, the locking portion and the projection come into contact with each other to prevent the opening operation of the tray door.

[0012]

According to this invention, a locking portion is provided on the back surface of the tray door formed separately from the tray of the disc player, while the tray driving mechanism is housed inside the disc player and sets up and down movement of the tray by the tray driving mechanism. And a projection is provided at the lower part of the tray that can be reproduced at the stored position.

This tray door is kept closed by the urging force of a spring, as in the prior art, and the opening and closing operation of the tray door is braked by a gear mechanism so as not to perform an abrupt opening and closing operation.

When the tray door is to be opened while the tray is housed inside the disc player, the locking portion of the tray and the projection of the tray come into contact with each other to prevent the opening operation of the tray door. it can.

As described above, even when the tray is stored in the main body and the reproduction is driven at a position where the tray does not descend, it is impossible to open the tray door as long as the tray is stored.

Further, since the locking portion of the tray door and the projection of the tray are in a position where they do not come into contact with each other when the tray door is closed, unnecessary vibration of the tray door is not transmitted to the tray, and the tray is not stored. There is no loss of disc playback quality.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the structure of a tray door of a disc player according to the present invention will be described with reference to FIGS. The same parts as those in the conventional example are denoted by the same reference numerals, and description thereof will be omitted. FIG. 1 is a side sectional view showing a state where a tray is housed inside a main body, and FIG. 2 is a top view of the same.

In the drawing, reference numeral 2 denotes a tray door, and a locking portion 2a extending inside the main body is formed on the back of the tray door 2. Reference numeral 3 denotes a tray housed inside the main body, and a projection 3a is formed at a lower portion of the tray 3 on the panel side.

The structure of the tray door 2 of the disc player thus configured is such that the tray door 2 and the tray 3 are separated from each other, and the tray 3 housed inside the main body is, as shown in FIG. The disc is driven to be reproduced at the insertion position, and does not have a reproducing drive mechanism by vertical movement of the tray 3 as in the conventional example.

The tray door 2 is closed by the urging force of the spring 4, and the tray door 2 is normally fixed so as to be flush with the panel 1. The opening and closing operation of the tray door 2 is braked by the gear mechanisms 5 and 6 so as to perform a smooth operation.
In the state where is not stored inside the main body, the opening and closing of the tray door 2 can be arbitrarily and freely operated.

When the tray door 2 is opened and the tray 3 is inserted from the outside of the main body, and the tray 3 is stored in the reproduction fixed position as shown in the figure, the tray door 2 is completely closed by the urging force of the spring 4. Therefore, the locking portion 2a of the tray door 2 and the tray 3
Of the tray door 2 on the panel 1
Is not transmitted to the tray 3.

When the tray door 2 is to be opened in a state where the tray 3 is housed in the main body as described above, when the tray door 2 operates in the opening direction, the locking portion 2a of the tray door 2 causes the protrusion of the tray 3 to be protruded. Locked to the portion 3a, the tray door 2 is prevented from opening and cannot be opened.

It is possible to avoid that the tray 3 is stored in the main body to perform a disc reproducing operation, or that the tray door 2 is opened carelessly during the storing of the tray 3 before or after the reproduction.

The above-described disc player can be applied to, for example, an LD player for reproducing images and a CD player for reproducing sounds, in which the tray door 2 and the tray 3 are formed separately.

[0025]

As described above, the structure of the tray door of the disc player according to the present invention is reproduced and driven at the position where the tray is inserted into the main body, and the tray does not move up and down as in the conventional example. The locking operation of the tray door and the projection of the tray prevent the opening operation of the tray door in a state in which the tray is housed, and the tray door cannot be opened, thereby ensuring the quality in disc reproduction. it can.

Further, since the tray does not need to be moved up and down, the time required for reproducing the disc can be shortened, the driving mechanism of the disc player can be simplified, and the cost can be reduced. There is an effect that the performance can be improved.

In addition, it has excellent features such as a simple structure and easy implementation because it can be constructed at low cost.
