No.).

In this prior invention, the slide pull on which the disk is placed is provided with a 1 arm and 7 arm along the direction of its moving force,
This rank is driven by a vinyl on which is rotationally driven by an electric motor, and the slide table is pulled into the player body from the ejection position where it is pulled out of the player body. Move to storage position (loading) 1
Also, the slide table was configured to be moved (unloaded) from the stowed (☆; 6') position to the lJi extended position (unloaded) by reverse rotation of the electric motor.

D Problems to be Solved by the Invention However, a fairly large torque is required to move the slide table between the (111) exit position and the stowed position. As in the claimed invention, the slide/slide table is moved by an electric motor.
In this case, it is necessary to use an electric motor that can provide a large 1-back, which results in extremely high costs.

Furthermore, as is well known, the compact disc used in compact disc players has a very small diameter of 12 cm, and portable compact disc players have been developed to take advantage of this advantage. In this case, it will be battery powered, but as mentioned above, the electric motor that can provide a large torque consumes a lot of battery power. For this reason, a large battery with a large capacity must be used, which is inconvenient for portable devices that require smaller size and lighter weight.

Therefore, the present invention makes it possible to move the slide table from the storage position to the ejection position without using an electric motor.

E. Means for Solving the Problems The present invention provides that in the above-described disc player, as the slide table is moved from the ejection position to the storage position, the driving force for moving the slide table from the storage position to the ejection position is gradually accumulated. It is equipped with a driving means (for example, a tension coil spring or a mainspring).

F Function The present invention is such that when the slide table is moved from the ejection position to the storage position, driving force (spring force) for moving the slide table from the storage position to the ejection position is gradually accumulated in the driving means such as a tension coil spring or a mainspring. be done. This accumulated driving force moves the slide table from the storage position to the ejection position.

The front end surface of the horizontal guide bearing 21 is in contact with the front wall 25a of the i1f straight chassis 25 on the - side, and the slide [
The movement of the table 5 is stopped, and the movement of υ1 is completed.

As the slide table 5 is moved from the ejection position to the storage position, the tension coil spring 40 is gradually stretched, and the scoop 1 is inserted into the tension coil spring 40.
: The driving force (spring force) that moves the table 5 from the storage position to the ejection position is gradually accumulated, so when the slide table 5 is unlocked in the storage position, the accumulated driving force moves the sleigh 1. The table 5 is moved from the storage position to the ejection position.

By the way, the driving means using the tension coil spring 40 has an extremely simple structure and can be placed in an extremely small space inside the player body 1, and there is no need to use gears, etc., so there is no need to worry about gear noise etc. do not have. Furthermore, as in the embodiment, by guiding the guide pulley 3EH and using the tension coil spring 40 with a long free length,
Even if the slide table 5 has a long movement distance, springs with a small spring constant can be used, so the slide table 5 can be moved extremely smoothly.

G. Next, details of another drive stage and its operation will be explained with reference to FIGS. 6 and 7.

In this case, the drive means is a mainspring (thinly wound spring) 81
It was constructed by First, a pair of gears 82 and 83 are rotatably supported on the outer surface of the vertical shaft 25 in the player body 1 near both front and rear ends.

A guide boo IJ 92 is integrally formed with the intermediate gear 85, and a guide pulley 93 is also rotatably supported near the guy 1' gear 82 on the front end side. A timing heald 94 is wound along the front-rear direction between the pair of guide gears 82 and 83. Furthermore, a pair of guys)・
Pulleys 92 and 93 are located at the bottom 4-1 of the timing held 94.
- The timing bell I and 9 are arranged so as to be pushed by the force, and thus the timing bell I and 9 are connected to the pair of guide gears 82 and 83.
Winding number 4 has a large angle.

A part of the timing bell I 94 is fixed to the 11ζ surface of the horizontal guy 1 bearing 21 of the slide table 5 by a screw 95 or the like.

According to the above example, when the slide table 5 is pushed from the ejection position to the storage position in the direction of the arrow a, as shown by the dashed line from the solid line in FIG. 6G, the timing belt 94 is driven along with this movement. , drive gear 84 and middle II old +

Note that the present invention is applicable to various types of disc players that use various types of audio discs and video discs, in addition to the Combat 1-disc player.

EFFECTS OF THE INVENTION The present invention utilizes a driving means that gradually accumulates the driving force for moving the slide table from the storage position to the ejection position as the slide table is moved from the ejection position to the storage position. Therefore, it is possible to move the slide tape 2 full from the storage (1) position to the ejection device (automatic transfer 1) without using an electric motor. (This means that there is no need for an expensive electric motor that generates a large torque to move the slide 1" table, and it is possible to reduce losses. Since there is no need for an electric motor to move the disc player, even in the case of Hanokerry drive, all that is required is the battery capacity required for the disc rotation drive motor, and there is no need to use a large battery with a large capacity. This greatly facilitates miniaturization and weight reduction, which is very convenient for portable disc players.
