DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk feed mechanism of a disk player, and more particularly to a disk feed mechanism for automatically pulling a disk placed on a tray into and out of the disk player.

[0002]

2. Description of the Related Art Generally, discs such as compact discs and laser discs are put in a jacket.
At the time of use, the disc was taken out of the jacket and manually inserted into the disc reproducing apparatus, and the disc was taken out after the end of the reproduction.

[0003]

However, in a disc player of the autochanger type in which a disc is placed on a tray and the tray is moved to feed the disc to a reproducing apparatus, the above-mentioned prior art cannot be applied. A retraction and delivery mechanism is required.

Therefore, the present invention provides a disk reproducing device by providing rollers and a disk detecting means near the entrance of the disk so that the disk placed on the tray can be automatically fed into the reproducing device and can be fed out after the reproduction. It is an object of the present invention to provide a disk feeding mechanism of a disk reproducing apparatus.

[0005]

SUMMARY OF THE INVENTION The present invention, in the entrance provided in the vicinity of the disk entrance of disk playback device
To pull the inserted disc into the playback device
And roller, a tray the disc is placed, the
Move the tray in the direction of the playback device and place it on the tray.
Tray retraction to insert the placed disc into the entrance
Gear and the tray has been moved in the direction of the playback device
Sometimes detects the disc loaded on the tray
It is characterized in that a disc sensing means for rotating said roller by.

[0006]

When the tray is moved in the direction of the disc reproducing apparatus and the disc on the tray is inserted into the entrance of the disc, the disc detecting means detects the disc, rotates the roller, and contacts the rotating roller. , The disc is pulled into the playback device. After the end of the reproduction, the rollers are reversed and the disc is sent out onto the tray.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 are views showing an embodiment of a disk feed mechanism of a disk reproducing apparatus according to the present invention. First, the configuration will be described. In FIG. 1, reference numeral 100 denotes a disk player. The disk player 100 has a storage box 1 having a storage section 26 for storing a tray 12 on which a disk 11 is placed.
0 and a moving unit 25 having a mechanism capable of moving a disk reproducing device 28 (hereinafter abbreviated as a reproducing device) for reproducing the disk 11 up, down, left and right behind the storage unit 26.

Each storage section 26 is provided with a tray pull-in gear 27. By driving the gear 27, the tray 12 in the storage section 26 is moved toward the reproducing device 28, and the disk 11 in the tray 12 is reproduced. It is adapted to be guided into the device 28.

The moving section 25 communicates with each of the storage sections 26, has a space in which the reproducing apparatus 28 can be moved in the upper, lower, left, and right directions, and is formed with the upper and lower parts opened. . A vertically moving rack member 29 made of a long material having an L-shaped cross section is fixed to the left and right walls of the moving portion 25. The rack member 29 is formed with a rack 29a in which a vertically moving gear meshes. Have been.

[0010] The reproducing apparatus 28 is mounted on a moving table 30 which moves in the vertical direction. The movable table 30 has a slider 31 whose both sides slide along the vertical moving rack member 29.
And the vertical movement gears provided on both sides of the back surface of the movable base 30 are connected to the rack 29 of the rack member 29.
a to move in the vertical direction or stop it. The moving table 30 is vertically moved by a drive motor of a vertically moving gear mounted on the back surface of the moving table 30, whereby the reproducing device 28 moves up and down.

The reproducing device 28 can be moved in the left and right directions and stopped by a left and right moving gear meshing with a rack 32a of a left and right moving rack member 32 provided on the surface of the moving table 30. At this time, the left and right movement gears are mounted on the lower surface of the reproducing device 28 together with the drive motor.

A rubber roller 34 is mounted inside the disk entrance 38 at the front of the reproducing device 28 so as to face a smooth resin guide plate 36 mounted on the lower surface of the top plate 28A of the reproducing device 28. . This rubber roller 34
As shown in FIG. 3, the center 35 has a tapered surface with the smallest diameter and the diameter increases toward both ends. Are in contact with each other.

A gear 37 is mounted on the shaft of the rubber roller 34. The gear 37 is driven by a motor (not shown) provided in the reproducing device 28 so that the rubber roller 34 rotates. I have. Numeral 39 denotes a disk detecting piece. The disk detecting piece 39 is attached to the upper top plate 28A of the disk entrance 38 at the front of the reproducing device 28 so as to be movable left and right along the disk entrance 38. The tray 12 moves to the playback device 28 side, and the tray 12
When the upper disk 11 engages with the detection piece 39 and the disk detection piece 39 moves left and right by a predetermined amount, the disk detection piece 3
9, a detection switch (not shown) is operated, and the motor driving the rubber roller 34 starts to rotate forward. The disk detecting piece 39 and the detecting switch constitute a disk detecting means. When the leading edge of the disk 11 comes into contact with the center of the rubber roller 34, the disk 11 is sandwiched between the guide plate 36 and the rubber roller 34, drawn into the playback device 28, and stopped at a turntable position (not shown) in the playback device 28. It has been made like that. Further, the disk 11 after reproduction is ejected onto the tray 12 from the disk entrance 38 in the reverse direction by the reverse rotation of the motor.

Next, the operation will be described. The playback device 28 moves left and right along the rack member 32 and up and down via the rack 29a, stops at the position of a desired disc, and the tray 12 on which the disc is placed is moved via the gear 27 to the playback device. Move in the direction of 28. When the leading edge of the disk 11 on the tray 12 engages with the detection piece 39 and moves the detection piece 39 right and left by a predetermined amount, the detection switch is activated,
The motor starts rotating forward, and the rubber roller 34 starts rotating.
When the disc 11 is further inserted, the front edge of the disc 11 is sandwiched between the guide plate 28A and the rubber roller 34, and with the rotation of the rubber roller 34, the disc is drawn into the turntable of the reproducing device 28 and set. . When the reproduction is completed, the rubber roller 34 rotates in reverse with the reverse rotation of the motor, and the disk 11 is moved from the disk entrance 38 to the tray 1.
2 is discharged.

[0015]

As described above, according to the present invention,
Since a rubber roller and a disc detecting means for feeding and unloading a disc are provided at the disc entrance and exit of the disc reproducing apparatus, the disc mounted on the tray can be automatically fed into and out of the reproducing apparatus. It is possible to select an arbitrary disc from the discs and reproduce it with a simple configuration at a low cost.
