Description

Description: TECHNICAL FIELD The present invention relates to a disc player, and more particularly to a multi-disc player capable of accommodating a plurality of discs and sequentially selecting any of the discs contained therein for continuous performance.

BACKGROUND ART A jukebox is generally known as a disc player capable of accommodating a plurality of discs and sequentially selecting any of the discs contained therein to enable continuous performance. However, the conventional jukebox itself has a very large body and is not suitable for home use.

In recent years, it is called a digital audio disk (hereinafter, abbreviated as DAD), and can record more digital information than a conventional audio disk containing analog signals. Several types of discs that generate less noise during development have been developed and are widely used. Among them, especially the method of recording and reading a signal by using a laser beam, a disc generally called a compact disc having an outer diameter of about 12 cm is easy to handle and enables downsizing of the entire disc player. is there. Recently, multiple small DADs (eg 5-6
A multi-disc player has been developed that can be stored at any time and is optimal as a home jukebox that plays these continuously. By the way, the performance time for a small DAD is 1
It can hold about 1.5 times as much information as conventional analog audio discs. Therefore, for example, 6
About 120 songs can be accommodated in a single disc if the playing time is about 3 minutes, and it is easy to cover each genre such as jazz or enka.

A multi-disc player is basically a playing means including a turntable, a pickup, etc., a disc holder for holding a plurality of discs in an array and inserting the disc holder into a mounting portion in the player housing, and an arbitrary disc holder inside the disc holder. Discs are sequentially selected and the disc take-out / conveyance mechanism for conveying the discs to the play position, that is, the turntable is provided.

In the multi-disc player, when carrying the desired disc in the disc holder onto the turntable,
For example, the disc is moved in two directions parallel to the disc carrying surface of the turntable and substantially perpendicular thereto. However, in the already-developed multi-disc player, the disc take-out / conveyance mechanism for carrying out this conveyance directly moves the disc in the disc holder directly to the end of the disc in the protruding direction from the disc holder or substantially the entire disc. This is a type of gripping and pulling out to the outside of the disc holder, and the structure of the disc ejecting and transporting mechanism including the gripping mechanism for gripping the disc is large and complicated, and the space required for its operation is large, and the entire player As a result, it is difficult to reduce the size, and the cost is increased.

Recently, as a solution to this problem, for example, JP-A-60-82.
As disclosed in Japanese Patent No. 759, the disc holder includes a housing, and a plurality of plate-like trays each capable of carrying a disc on its main surface and projecting and accommodating along the main surface with respect to the housing. Has been newly developed. That is, it is configured such that the plate-shaped trays carrying the respective discs can be conveyed in one direction (the discs can be conveyed in the direction parallel to the disc-carrying surface of the turntable) simply by protruding from the housing. -ing Therefore, like the above-mentioned multi-disc player,
A disk ejecting and conveying mechanism of a type in which the disk housed in the disk holder is directly grasped at the end of the disk in the protruding direction from the disk holder or substantially the entire disk by a complicated gripping mechanism and pulled out to the outside of the disk holder The structure is simpler than that of the player, and it is easy to reduce the cost for downsizing the player as a whole.

However, in this multi-disc player, when the disc is housed in the disc holder, the disc has a label surface as a lower face and is placed on the tray, that is, the playing means is configured to be accessed from above the disc. When checking the disc before mounting the disc holder on the player body, you cannot check the disc simply by protruding the tray from the holder body, and you can put it in your hand and turn it over. It was troublesome and could not stand the trouble.
