Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disc player, and more particularly to an autoloading mechanism that automatically loads a disc.

In conventional disc players, in order to play the disc, the user usually has to manually load the disc onto the turntable, which is very cumbersome.

Furthermore, even if a machine that automatically v7iWs a disc is provided, the mechanism is extremely complicated, and therefore, handling of the low disc stabilizer of the player is difficult.
Many of the mechanisms were complex and difficult to operate. for example,
In a loading mechanism equipped with a stabilizer as described above, in order to prevent the stabilizer from becoming an obstacle when installing the disc on the turntable, the stabilizer must be moved by rotating the holder to which the stabilizer is attached, or the stabilizer must be moved separately. A device was installed to remove the stabilizer.

The main object of the invention is to provide an autoloading mechanism that eliminates the above-mentioned drawbacks.

The above objects and other objects and features will become more apparent from the detailed description given below with reference to the drawings.

FIG. 1 is a right side view of a disc player equipped with an autoloading mechanism according to an embodiment of the present invention, in which a portion of a disc holder is shown in cross section.

In this embodiment, basically there are a main body 1oo and a main body 10.
a disc holder 200 that is movably attached to the main body 100 and holds the disc 1; a link mechanism that moves the disc holder 200 relative to the main body 100;
A turntable 15 provided at 0 is provided with a pressing means for pressing the disc 1 and an If removing means for releasing the pressure from the pressing means.

While mainly explaining the above-mentioned link mechanism, pressing means, and releasing means, other configurations will also be described.

The above link mechanism will be explained with reference to FIG. In the configuration, a motor 22 is attached to the outside of the side plate 12 of the main body 100. The motor 22 is connected to a predetermined circuit and rotates in two directions: forward and reverse. A pulley 52 is fixed to the output shaft of the motor 22.
The rotation of the motor 22 is transmitted to the pulley 54 by a belt 24 wound around the motor 2 . A worm gear 25 is coaxially attached to the pulley 54, and a gear 23 is provided to engage with the worm gear 25. In addition, the gear 23 has a link 21 at an eccentric location.
One end is pivoted. Therefore, the rotational motion transmitted from the motor 22 now becomes a reciprocal motion by the link 21. Further, the other end of the link 21 is pivotally supported by one end of the lever 17 that rotates around the shaft 18. The other end of the lever 17 is pivotally connected to the arm portion 202 of the disc holder 200 by the post 19 via the opening 102 . Note that the shaft 18 passes through the main body 100 (FIG. 2), and a lever, an arm portion, etc. are also provided on the opposite side of the side plate 12, but in the following description, only the side plate 12 side will be described. The disc holder 200 is supported by the main body 100 by a boss 11 provided on the disc holder 200 and a guide groove 104 provided in the main body 100. Therefore, the disk holder 200
1 and is slidable in the length direction of the guide groove 104.

In operation, current from a predetermined circuit causes motor 2 to
2 rotates. The rotation of the motor 22 is controlled by the worm gear 25 via the pulley 52, the belt 24, and the pulley 54 in this order.
The worm gear 25 rotates accordingly.

When the worm gear 25 rotates, the gear 2 that engages with it
3 will rotate at a reduced speed. Here, gear 23
Assume that the direction of rotation is toward the arrow. As the gear 23 rotates in the forward direction, the link 21 whose one end is pivotally supported by the gear 23 is pulled in the direction of arrow B. When the link 21 is pulled in eight directions, the lever 17 pivotally connected to the other end rotates about the shaft 18 in the direction of arrow C. When the lever 17 rotates and the post 19 moves within the opening 102, the arm portion 202 of the disc holder 200 is pulled accordingly. At this time, it moves in the direction of the main body 100 by sliding.

Therefore, the disc holder 200 moves from the non-reproducing position shown in FIG. 1 to the reproducing position shown in FIG. 3. As the disc holder 200 moves in this manner, the disc 1 held within the disc holder 200 is carried onto the turntable 15[i. Thereafter, the disk 1 is pressed against the turntable 15 and mounted by a pressing means to be described later.

Figure 2 is a front view of this embodiment, W2 (Figure 1)
is shown removed. FIG. 3 is a right side view, partially shown in section, of this embodiment with the disc holder moved to the playback position and the disc mounted on the turntable.

With reference to FIGS. 1 to 3, the pressing means, the releasing means, and the disc holder will be mainly explained. In the configuration, referring to 1wJ and 2, the disk holder 20
A circular opening is formed in the middle plate 9 of 0, and the cylindrical stabilizer 4 is inserted into the opening. Seven flanges are formed at both ends of the stabilizer 4, respectively. A magnet 5 is attached to a flange formed on the turntable 15 side, and the stabilizer 4 is held within the recess 34 by being magnetically attracted to the middle plate 9 made of a magnetic material. Further, a plate spring 7 that rotates around a shaft 8 is provided on the middle plate of the disc holder 200. When the disc holder 200 moves toward the main body 100, the leaf spring 7 has both ends contacting the steel ball 6 provided at the top of the stabilizer 4 and the post 27 provided on the base plate 13 of the main body 100, respectively. positioned so that they touch each other. The disk holder 200 that holds the disk 1 has a passage hole 3 for inserting and removing the disk 1, and a protrusion 32 (Fig. 2) with which the disk 1 comes into contact and determines its approximate position. is provided.

In operation, when the disc holder 200 is in the non-playback position as described above, the disc 1 is set in the disc holder 200 through the passage port 3. At this time, the stabilizer 4 is held in the middle plate 9 by the magnet 5 in a retracted form into the recess 34, and insertion of the disk 1 is not hindered.

After disc 1 is set in disc holder 200,
By operating the switch, the disc holder 200 is rotated clockwise and the main body 10 is rotated by the above-mentioned link mechanism.
Vibratory movement in the direction of 0. As the disc holder 200 moves toward the main body 100, the leaf spring 7
, and one end of the leaf spring 7 approaches the direction of the substrate 1.
It is pushed by the post 27 provided at 3. When the leaf spring 7Q-man end is pressed, the leaf spring 7 rotates and the other end presses the steel ball 6. This pressing force is applied to the disc holder 2
00 increases as it moves toward the main body 100, and preferably exceeds the magnetic force of the magnet 5 after the adapter 16 is inserted into the hole of the disk 1. Therefore, as shown in FIG. 3, since the magnet 5 is separated from the middle plate 9 and the stabilizer 4 is urged by the plate spring 7,
The stabilizer 4 presses the disc 1 against the turntable 15. The stabilizer 4 is provided with a recess into which the adapter 16 is inserted, and the disc 1 is securely held by the stabilizer If 4 and the turntable 15 (FIG. 3).

As shown in FIG.
It rotates together with the turntable 15 and adapter 16, and the recorded information is reproduced by a pickup device (not shown). Note that while the disc 1 is rotating for playback, the stabilizer 4 is biased by a leaf spring 7 in order to press and hold the disc 1, but the leaf spring 1 is connected to the steel ball 6 at a point. Since they are in contact and the point of contact is located at the center of rotation, it does not affect the rotation of the disk 1 in any way.

In addition, in order to take out the disk when the playback of the disc 1 is finished, etc., by rotating the motor 22 in the opposite direction, each of the above-mentioned operations or the above-mentioned operation improvement can be achieved. The disc 1 can be easily taken out. The operation will be simply explained with reference to FIG. The above-mentioned motor 22 (Fig. 1) is connected to the disc 1 on the turntable 1.
Rotate inward in the opposite direction to when arriving at #5. Then, the third
From each configuration shown in the figure, the lever 17 rotates in the direction of the arrow. As a result, the mib is moved away from the main body 100 while holding the disc. According to this movement, the force with which the C1 post 27 presses the leaf spring 1 becomes weaker, and therefore the force with which the leaf spring 7 presses the steel ball 6 becomes weaker. Therefore, the stabilizer 4 is attracted to the middle plate 9 by the magnetic force of the magnet 5, and the turntable 1 of the disk 1 is
The pressure on 5 is released. At the same time, the stabilizer riser 4 is held on the middle plate 9 by the magnet 5, so that it does not become an obstacle when the disk 1 is removed or inserted.

In this way, the pressure of the disc 1 on the turntable 15 is released, and the disc holder 200 is placed in the first position all (
1), the current to the motor 22 is cut off and each component comes to rest.

In the above embodiment, the magnet 5 is attached to the stabilizer 4 and the middle plate 9 is made of a magnetic material, but the magnet may be attached to the middle plate 9, and in this case, the magnet 5 is attached to the stabilizer 4 and the middle plate 9 is made of a magnetic material.
By using a magnetic structure, the above-described pressing means and releasing means can operate more reliably. Moreover, if the disc holder 200 is made to rotate largely toward you, the stabilizer 4 can
The shape of the magnet being pulled into the recess 34 by self-deprecation, not by magnetic force, makes the magnet particularly unpopular. Although the above explanation C has been described for the case where the disc 1 is played back in a vertical plane, the same effect is produced even when the disc 1 is played back in a horizontal plane.

As described above, according to the present invention, the stabilizer for rotating the disc stably does not become an obstacle when inserting the disc, and the autoloading mechanism that allows the disc to be loaded with an easier operation is provided. can get.
