Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Generally, a disc such as a compact disc or a laser disc is 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 by hand even after the reproduction was finished.

[0003]

However, the above-mentioned conventional technique cannot be applied to an automatic changer type disc player in which a disc is placed on a tray and the tray is moved to feed the disc to a reproducing device. A retracting and delivering mechanism is required.

Therefore, according to the present invention, by providing a roller and a disc detecting means in the vicinity of the disc entrance / exit of the disc reproducing device, the disc placed on the tray can be automatically fed into the reproducing device and can be ejected after the reproducing. It is an object of the present invention to provide a disc feeding mechanism of a disc reproducing device.

[0005]

SUMMARY OF THE INVENTION According to the present invention, in a disc feeding mechanism of a disc reproducing device for inserting and ejecting a disc placed on a tray, a roller provided near a disc inlet / outlet of the disc reproducing device, Disk detection means for detecting the insertion of the disk on the tray into the disk inlet / outlet and rotating the roller.

[0006]

When the tray moves toward the disc reproducing device and the disc on the tray is inserted into the disc inlet / outlet, the disc detecting means detects and rotates the roller, so that the disc comes into contact with the rotating roller. , The disc is pulled into the playback device. After the reproduction is completed, the rollers reversely rotate and the disc is sent out onto the tray.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 are views showing an embodiment of a disc feeding mechanism of a disc reproducing apparatus according to the present invention. First, the configuration will be described. In FIG. 1, reference numeral 100 denotes a disc player, and the disc player 100 has a storage box 1 having a storage portion 26 for storing a tray 12 on which a disc 11 is placed.
0 and a moving unit 25 having a mechanism capable of moving a disc reproducing device 28 (hereinafter abbreviated as a reproducing device) for reproducing the disc 11 vertically and horizontally to the rear of the housing 26.

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

The moving section 25 communicates with each storage section 26, has a space in which the playback device 28 can be moved in the upper, lower, left, and right directions, and is formed so that the upper and lower portions are open. . A vertical movement rack member 29 made of a long material having an L-shaped cross section is fixedly mounted on the left and right walls of the moving portion 25. The rack member 29 is formed with a rack 29a meshed with a vertical movement gear. Has been done.

The reproducing device 28 is mounted on a moving base 30 which moves in the vertical direction. The moving table 30 has sliders 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 table 30 are connected to the rack 29 of the rack member 29.
It is adapted to engage with a and move up or down, or to stop. The vertical movement of the movable table 30 is performed by a drive motor of a vertical movement gear attached to the back surface of the movable table 30, whereby the reproducing device 28 is vertically moved.

Further, the reproducing device 28 can be moved in the left-right direction and stopped by the left-right moving gear meshing with the rack 32a of the left-right moving rack member 32 provided on the surface of the moving table 30. The left and right moving gears at this time are attached to the lower surface of the reproducing device 28 together with the drive motor.

Inside the disk inlet / outlet 38 at the front of the reproducing device 28, a rubber roller 34 is attached so as to face a smooth resin guide plate 36 attached to 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 the smallest diameter and has a tapered surface with the diameter increasing toward both ends, whereby the rubber roller 34 is provided on the outer peripheral edge which is the non-recording surface of the disk 11. Are in contact with each other.

A gear 37 is attached to the shaft of the rubber roller 34, and the rubber roller 34 is rotated by driving the gear 37 by a motor (not shown) provided in the reproducing device 28. There is. Reference numeral 39 denotes a disc detecting piece, and the disc detecting piece 39 is attached to the upper top plate 28A of the disc inlet / outlet 38 at the front part of the reproducing device 28 so as to be movable left and right along the disc inlet / outlet 38. The tray 12 moves to the playback device 28 side, and the tray 12
When the upper disk 11 is engaged with the detection piece 39 and the disk detection piece 39 moves left and right by a predetermined amount, the disk detection piece 3
A detection switch (not shown) connected to 9 is actuated, and the motor for driving the rubber roller 34 starts to rotate in the normal direction. The disc detection piece 39 and the detection switch constitute a disc detection means. When the front edge of the disk 11 comes into contact with the central portion of the rubber roller 34, the disk 11 is sandwiched between the guide plate 36 and the rubber roller 34, drawn into the reproducing device 28, and stopped at a turntable position (not shown) in the reproducing device 28. It is done like this. Further, the disc 11 after being reproduced is reversely moved as described above by the reverse rotation of the motor and is ejected from the disc inlet / outlet 38 onto the tray 12.

Next, the operation will be described. The reproducing device 28 moves left and right along the rack member 32 and up and down via the rack 29a, stops at a desired disc position, and the tray 12 on which the disc is mounted is transmitted through the gear 27 through the reproducing device. Move in the direction of 28. Then, when the front edge of the disk 11 on the tray 12 is engaged with the detection piece 39 and the detection piece 39 is moved right and left by a predetermined amount, the detection switch is activated,
The motor starts to rotate normally, and the rubber roller 34 starts to rotate.
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 the disc is drawn and set on the turntable of the reproducing device 28 as the rubber roller 34 rotates. . When the reproduction is completed, the rubber roller 34 is reversely rotated in accordance with the reverse rotation of the motor, and the disk 11 is moved from the disk inlet / outlet 38 to the tray 1.
2 discharged on top.

[0015]

As described above, according to the present invention,
Since the rubber roller and the disc detecting means for feeding and ejecting the disc are provided at the disc inlet / outlet of the disc reproducing device, the disc placed on the tray can be automatically fed into / out of the reproducing device, and accordingly, a large number of discs mounted on the tray can be provided. It is possible to implement it at low cost with a simple configuration in which an arbitrary disc is selected from the discs and reproduced.
