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.

Moreover, the left end thereof is swingably attached to the carrying member via a pin 29a. A pin 12a that supports the support 29 is provided on the moving member 12. Support 29
At the left end of the disc 5, there is a disc-shaped pressing member 30 that abuts on the surface of the disc 5 opposite to the turntable 15 and cooperates with the turntable to perform a disc clamping action.
It is rotatably attached via. These supports
29 and the pressing member 30 constitute a clamp mechanism for clamping the disc 5.

Next, the operation of the multi-disc player having the above-mentioned configuration will be briefly described according to the playing procedure.

First, when the disc to be played is designated by pressing the operation button, the moving member 12 moves up and down.
Therefore, the tray protruding member 19 provided on the moving member 12
Reach the position of engagement with the tray 6 carrying the disc to be played. After this, the cam bodies 20 and 21 are driven to the right (counter arrow X direction) and left, respectively. Therefore, the tray protruding member 19 rotates counterclockwise in FIG. 1 about the rotation support shaft 8 which is the virtual rotation center. As a result, the tray 6 carrying the disk 5 to be played protrudes from the magazine body 4, and the disk 5 moves to a concentric position with respect to the disk carrying surface of the turntable 15, that is, just above the disk carrying surface. After that, the cam bodies 20 and 21 are further driven, and the cam portions 20a and 21a formed at both ends of the both cam bodies are driven.
Passes through a pin 27 protruding from the carrying member 13. As a result, the carrying member 13 is driven upward (in the direction of arrow Z), the disk carrying surface of the turntable 15 contacts the lower surface of the disk 5 on the tray 6, and the disk is set on the turntable 15. At the same time, the pressing member 30 clamps the disc.

Thus, the performance becomes possible, and the turntable 15 and the carriage 17 operate to start the performance. When the performance is finished, the disc 5 is stored in the magazine main body 4, but the disc storing operation is performed in the reverse process of the disc loading operation described above, and thus the detailed description thereof will not be given. Thereafter, the above operation is repeated according to the designated curve.

Effect of the Invention As described in detail above, in the multi-disc player according to the present invention, the playing means including the turntable and the pickup is also mounted on the moving member which carries the tray protruding member and moves in the tray arrangement direction of the disc holder. ing.

Due to such a structure, the disc can be quickly loaded into the playing means. What happens is that if the playing means is provided not on the moving member but on the fixed side, in order to convey the disk to be played onto the turntable, the tray carrying the disk should be projected out of the magazine. Therefore, it is necessary to move the discs in one direction, and then the discs need to be largely moved also in the tray arrangement direction perpendicular to the projecting direction, which increases the disc transport time. It should be noted that the moving distance of the discs in the tray arrangement direction becomes larger as the discs on the trays located farther from the playing means out of the arranged trays. As described above, in the multi-disc player according to the present invention, the playing means is mounted on the moving member together with the tray projecting member and moves in the tray arranging direction, so that the disc to be played is transported to the turntable. This is completed by simply protruding the carried tray out of the magazine, and the disc transport time is shortened. Further, as described above, in the multi-disc player according to the present invention, since the disc transport time, that is, the transport distance is short, downsizing of the disc ejecting and transporting mechanism, and further downsizing of the player as a whole, has been achieved. . Further, in the multi-disc player according to the present invention, the disc (5) carried on an arbitrary tray (6) protruding outside the housing (magazine body 4) of the disc holder (magazine 3) is loaded onto the turntable (15). The disk moving means, which moves in a direction substantially perpendicular to the disk carrying surface, is attached to a moving member (12) provided movably in the array direction of each tray in the disk holder so as to be movable in parallel in the array direction. A carrying member (13) mounted via a member (coil spring 14) and carrying playing means (turntable, pickup, etc.), and driving means for driving the carrying member, wherein the playing means is the housing. It is arranged on the side of the tray protruding outward that is opposite to the disk carrying surface. That is, after the desired tray is projected to the outside of the housing by the tray projecting means, the carrying member is driven so as to approach the tray from the side opposite to the disk carrying surface of the tray, that is, the lower surface side. The disk carrying surface of the disk contacts the lower surface of the disk on the tray so that the disk is set on the turntable. As described above, the pickup is arranged on the opposite side of the disc holding surface of each tray together with the turntable. Therefore, when the listener puts each disc on each tray in the disc holder, The recording surface is stored with the recording surface facing downward. Therefore, the listener always mounts the disc while checking it, with the side opposite to the recording surface of the disc, that is, the side on which the song title is written, as the upper side. Therefore, when loading a plurality of discs into the disc holder, it is unlikely that the discs will be placed in the wrong order, and the operability for loading the discs is good.

Also, in the multi-disc player according to the present invention, the playing means is attached to the carrying member via a vibration isolating member (coil spring 14). Therefore, the playing means is protected from external vibration, and a smooth playing state can be obtained.

Further, in the invention of the present application, in addition to such a configuration, the supporting means for movably supporting the above-mentioned carrying member in the vertical direction is a vibration isolating member, and the supporting means is also utilized as a vibration isolating means. As described above, the number of parts is reduced, the cost is reduced, and the size of the apparatus is reduced by performing two functions by one means.
