Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a disc changer, for example, a disc in which a tray having a plurality of disc mounting portions concentrically with respect to the center of rotation is rotatably accommodated in a cabinet and is reproduced at that rotation angle. Regarding the disc changer that makes the selection.

[0002]

[Prior art]

 A conventional disc changer is one in which discs are accommodated in parallel, one of the discs is selected and pulled out, and the disc is transported to the playback position to select the playback disc. There has been a method in which a disc mounting portion is provided at a position, the disc is conveyed to the reproducing position at the rotation angle of the tray, and the disc to be reproduced is selected.

In the latter method, as shown in FIG. 2, the tray 1 has its center supported by a shaft 2 and is rotated by a drive gear 3 which meshes with a gear around the periphery of the tray 1, and the rotation of the tray 1 causes the tray 1 to rotate. The disc mounting portion 1a is conveyed to a reproducing position where a turntable for rotating the disc and a pickup for reading a signal of the disc are installed.

In this disc changer, when the disc mounted on the mounting portion 1 a of the tray 1 is replaced, first, the tray 1 is guided by the guide members 5 on both sides of the tray, and the tray 1 is mounted on the cabinet 4. The loading section 1a is unloaded on the front side to expose the loading section 1a, and the disk loaded on the loading section 1a is replaced.

However, when unloading the tray 1 to the front surface, since the shaft 2 and the drive gear 3 project above the tray 1, they hit the upper edge 4 a on the front side of the cabinet 4, and the tray 1 is unloaded. However, only one of the plurality of mounting portions 1a is exposed to the outside of the cabinet 4 that rotatably accommodates the tray 1.

Then, the disk mounted on the mounting portion 1a exposed to the outside of the cabinet 4 is replaced, and the tray 1 is loaded in the opposite direction to the above to store the tray 1 in the cabinet 4. After that, the disk to be reproduced is selected by rotating the tray 1 as described above.

[0007]

[Problems to be solved by the device]

 However, in such a conventional disc changer, as described above, the mounting portion 1a that is unloaded on the front side of the cabinet 4 is only one of the plurality of mounting portions 1a, and the plurality of mounting portions 1a are not included. Unloading was not performed to the extent that the entire placement portion 1a was exposed.

Therefore, when all or at least two of the disks placed on the tray 1 are to be replaced, the loading and unloading of the trays must be performed by the number of disks to be replaced. However, there was a problem that it was troublesome.

The present invention has been made in view of the problems of the conventional disk changer of this type, and it is possible to replace the entire disk by once unloading the tray, and to simplify the labor of the replacement. To aim.

[0010]

[Means for Solving the Problems]

 According to the present invention, in a disc changer that accommodates a tray in a cabinet, in which a plurality of discs can be placed concentrically, and a disc to be played is selected by rotating the tray, the tray is rotated. Rotating means having a height lower than the lower surface of the upper part of the front edge of the cabinet, and feeding means for feeding all the tray mounting portions inside the cabinet to the outside of the cabinet are provided.

[0011]

[Action]

 The disc changer of the present invention is provided with a rotating means having a height lower than that of the upper portion of the front edge of the cabinet, and a feeding means for exposing all of the placing portions for placing the disc to the outside of the cabinet by loading the tray. Therefore, the disks placed on the tray are all exposed to the outside of the cabinet by the sending means without touching the upper part of the front edge of the cabinet by the sending means, and all or at least two or more disks can be replaced at once. It is a thing.

[0012]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 11 is a disc changer of the present invention, and the same reference numerals are used for the same components as those of the conventional one. In the disc changer 11, the tray 1 is provided with disc mounting portions 1a at a constant pitch angle in the circumferential direction, for example, at five locations on a concentric circle of the rotation center. When it is loaded inside, the disc mounted on the mounting part 1a is transferred to the turntable by the rotation by the pitch angle of the mounting part 1a, and the disc is moved to the reproduction position where the reproduction by the pickup is performed. The disc is transported and the disc to be played is selected.

In this disc changer, the tray 1 is unloaded on the front surface of the cabinet 4 for the purpose of exchanging the placed disc, but the loading means 14 as the sending means is the tray 1. A loading guide 15 on both sides and extended to the front side 15a has a drive motor (not shown) for sending the tray 1 to the front side along the loading guide 15. Further, the height of the drive gear 13 meshing with the gear formed on the peripheral edge of the tray 1 and the height of the shaft 12 of the center of the tray 1 are lower than the height of the lower surface of the upper front edge of the tray 1, that is, the height of the lower surface. A low rotating means 16 is provided. The loading means 14 has a loading guide 15 and a drive motor (not shown), and the rotating means 16 has a shaft 12 and a drive gear 13.

Next, the operation will be described. Since the disc changer 11 has the loading means 14 and the rotation means 16, the tray 1 is guided by the loading guide 15 by the drive of the drive motor, and the tray 1 and the rotation means 16 are placed at the five mounting portions 1a of the cabinet 4. Is unloaded on the outside of the cabinet 4 so that the entire surface of the cabinet is placed outside the front side of the cabinet 4. For this reason, it is possible to replace all the five discs of the mounting portion 1a at one time, and the labor for exchanging a plurality of discs can be greatly simplified as compared with the conventional disc changer.

[0015]

[Effect of device]

 According to the present invention, since the front surfaces of the plurality of disk mounting portions provided on the tray are all unloaded to the front surface of the cabinet, all the disks or two disks can be loaded by one loading and unloading operation. The above disks can be exchanged.

Therefore, unlike the conventional disc changer of this type, it is not necessary to repeat the loading and unloading operations for the number of discs to be exchanged, and the number of exchanges can be greatly simplified.
