Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc loading device for placing a disc on a turntable of a disc drive in an optical disc player, and more particularly, to a forward / backward movement direction of a slide table having a disc tray. The present invention relates to a disk drive device applied to a player in which a disk drive unit is arranged in a crossing direction.

[Conventional technology]

In some disc players in which a disc such as a CD (compact disc) is loaded, a disc tray on which the disc is installed moves back and forth with respect to the apparatus main body.
In this type of player, when the disc tray is projected, the disc is installed on the disc tray, and when the disc tray is pulled into the main body of the device, the disc is held at that position by the turntable and the clamp member in the drive unit. The disc is sandwiched between the discs and the disc is reproduced.

[Problems to be Solved by the Invention]

However, in consideration of various aspects expected of the disc player in the future, it is assumed that the disc drive unit cannot always be arranged at the position where the disc tray is pulled in. For example, a recent vehicle-mounted CD player is equipped with a disc changer in which a cartridge containing a plurality of discs is loaded, and the discs are pulled out from the cartridge and reproduced.
When a player equipped with this disc changer is used for home use, it is necessary to have not only a cartridge mounting portion but also a disc tray capable of immediately supplying a single disc. In this case, if the disc drive unit is provided at the position where the disc tray is pulled in, it becomes difficult to reproduce the disc taken out from the cartridge. Therefore, in this type of disc player, it is necessary to take out the disc supplied into the main body of the apparatus by the disc tray to a position outside the advance / retreat operation area of the disc tray. However, a very complicated mechanism is required to take out the disc from the disc tray and send it to the disc drive unit.

The present invention solves the above-mentioned conventional problems, and when the disc tray is housed in the main body of the apparatus, the disc can be easily supplied to the disc drive unit located on the side of the advance / retreat operation area of the disc tray. An object of the present invention is to provide a disc loading device for such a disc player.

[Means for solving the problem]

A disc loading device in a disc player according to the present invention comprises a slide table provided so as to be movable back and forth from a device main body, a tray holder further moving relatively on the slide table along a moving direction of the slide table, A drive mechanism that retracts the tray holder further into the apparatus body than the slide table after the slide table advances and retracts in the apparatus body, and a disc tray supported by the tray holder so as to be projectable in a direction intersecting the advancing and retracting direction, It is characterized in that a feeding mechanism for feeding the disc tray from the retracted tray holder into the apparatus main body and a disc driving unit for driving the disc placed on the fed disc tray are provided. .

In the above, the slide table is provided with a tray stopper that restricts the disc tray from protruding from the tray holder, and when the tray holder is relatively retracted into the main body of the apparatus on the slide table, the tray stopper is provided. It is preferable that the disc tray is made to be able to protrude without being regulated by.

In addition, the slide table is provided with a stop stopper that is locked to a part of the apparatus body when retracted into the apparatus body and that operates in a direction in which the lock is released when moving forward from the apparatus body. A structure is provided in which a stopper regulating portion is provided to regulate the movement of the stop stopper in the releasing direction together with the tray holder when the holder relatively moves into the apparatus main body on the slide table. With this configuration, the protrusion of the slide table can be restricted with a simple structure.

Further, the feeding mechanism for feeding the disc tray from the tray holder retracted into the main body of the apparatus is provided with a roller for giving a moving force with the disc tray sandwiched therebetween, and with a discharging member for discharging the disc tray to a position hitting the roller. The structure may be

Further, according to the present invention, a cartridge mounting portion into which a disc cartridge accommodating a plurality of discs is loaded is provided at a position overlapping the retracted slide table in the apparatus body, and the disc loaded in the cartridge loading unit is provided. The disc withdrawing direction from the cartridge is the same as the disc tray protruding direction, and the disc withdrawn from the disc cartridge and the disc placed on the disc tray are driven by a common disc drive unit. be able to.

[Work]

In the above means, the disc is set on the disc tray on the slide table protruding from the apparatus main body. When the slide table retracts into the main body of the device, the disc tray provided on the slide table is pushed out in the lateral direction together with the disc, with the disc installed.
The disc feeding mechanism feeds the disc tray together with the disc into the disc drive unit. Then, in the disc drive unit, the disc is held between the turntable and the clamp member, and the disc reproducing operation is performed.

In the above, the tray holder supporting the disc tray can move relative to the slide table, and after the slide table moves into the main body of the device, the tray holder further moves inward, so that the disc drive Even if the unit is located inside the main body of the apparatus, the disc tray protruding laterally from the tray holder can be reliably loaded into the drive unit.

Also, by providing a tray stopper on the slide table and allowing the disc tray to project only when the slide table retracts into the main body, it is possible to prevent the disc tray from moving when the slide table is ejected from the main body of the device. become.

Further, when the slide table is retracted inside the apparatus main body, a stop stopper that locks a part of the apparatus main body is provided, and release operation of the stop stopper can be regulated when the tray holder is further retracted. By
It is possible to prevent the slide table from protruding when the disc tray is moving toward the disc drive unit.

Further, when the slide table is pulled in the main body of the apparatus, the disc tray is pulled out in the lateral direction together with the discs. Therefore, even when the slide table and the disc cartridge are provided in two stages, the discs provided on the lifting table are provided. The feeding mechanism allows the disc in the cartridge and the disc tray to be pulled out under the same conditions and fed to the disc drive unit.

Further, by opening the roller of the feeding mechanism that has moved to the side of the disc tray, both the pulling-in operation of the disc inside the cartridge and the pulling-in of the disc tray can be performed by the same feeding mechanism.

Comes off the stop stopper 15. At this time, the tray holder 6a contacts the front side plate 5a of the slide table 5. After that, since the stop stopper 15 can rotate upward, the slide table 5 projects from the main body chassis 1.

Next, when the disc in the disc cartridge C is reproduced, the elevating table 20 rises to a position facing the side of the disc cartridge C. Lifting table
When the 20 is raised, as shown in FIG.
The arm 44a separates from the bottom plate 1b, and the upper roller 43 comes into close contact with the lower roller 42 by the force of the spring 46. When the elevating table reaches a position facing a predetermined disc in the disc cartridge C, the ejection member 52 pushes the ejector 61 of the disc cartridge C shown in FIG. 16 to eject the desired disc. Then, the disc is nipped by the upper roller 43 and the lower roller 42 which are in close contact with each other, and the disc is sent to the disc drive portion F by the rotation of the upper roller 43 to be reproduced.

〔effect〕

As described above, according to the present invention, the effects listed below can be obtained.

According to the first aspect of the present invention, when the slide table is retracted into the main body of the apparatus, the disc tray provided on the slide table is pushed out in the lateral direction together with the disc while the disc is installed, and the disc tray is driven by the disc feeding mechanism. Is sent to the disk drive unit together with the disk. Therefore, the disc can be fed to the end while being positioned on the disc tray, and even if the disc drive unit is provided outside the forward / backward movement area of the slide table, the disc is loaded at the position where it is securely clamped to the turntable. Become so.

Further, the tray holder supporting the disc tray further moves into the device body when the slide table moves into the device body, and the disc tray projects from the tray holder at that position. Therefore, even if the disc drive unit is located inside the apparatus body, the disc tray can be reliably loaded into the disc drive unit.

According to the second aspect of the present invention, the tray stopper is provided on the slide table so that the disc tray can project only when the slide table retracts into the main body. You can prevent it from moving.

According to the third aspect of the present invention, a stop stopper is provided that locks a part of the apparatus body when the slide table is retracted inside the apparatus body, and the stop stopper is released when the tray holder is further retracted. Since the operation can be restricted, the slide table can be prevented from protruding when the disc tray is moving toward the disc drive unit.

According to the fourth aspect of the invention, when the disc tray is pulled out from the tray holder, the disc tray is moved by directly receiving the force of the roller, so that the disc tray is surely moved.

According to the fifth aspect of the present invention, when the slide table is pulled in the main body of the apparatus, the disc tray is pulled out laterally together with the disc. Therefore, even when the slide table and the disc cartridge are provided in two stages,
By the common disc feeding mechanism provided on the lifting table, the disc in the cartridge and the disc tray can be pulled out under the same condition and fed to the disc drive unit.
