Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a disc player that is equipped with a plurality of magazines each containing a plurality of discs so as to be able to be taken out one by one.

BACKGROUND ART An example of a disc player that stores a plurality of discs in advance and selectively plays them is disclosed in Japanese Patent Application Laid-Open No. 1983 (1983). In such a disc player, the discs are arranged at narrow intervals, making it difficult to replace the discs. It's not always easy. Furthermore, it is necessary to cover the disc storage section with a housing to protect the disc, and it is also necessary to use an open/close type for replacing the disc. Therefore, if some of the discs are to be replaced after they have been stored, the housing must be removed and the labels of each disc must be checked while replacing them, which is cumbersome.

However, when such a disc player is used for karaoke, the range of requests is wide and there is not enough storage space to satisfy all requests, so discs that are requested frequently are stored in advance in the player's storage compartment. However, when a request is made for a song that is not on the pre-stored discs, a spare disc must be removed and replaced, but this is extremely difficult due to lack of time.

Next, the operation of the magazine disc player having the above-mentioned configuration will be briefly explained along the operating procedure with reference to FIGS. 10 to 13+d+.

First, when a disc to be played is specified by operating the operating section 3 shown in FIGS. 1 and 10, the first
A driving voltage is supplied to the motor 24 by the CPU (control unit) shown in FIG.
6 starts moving left (forward) or right (backward). Therefore, the push-out member 41 provided on the movable shear 16 pushes the tray 11 carrying the disc 10 to be played.
Alternatively, the engagement position with 12 is reached.

Here, the movement and positioning of the movable chassis 16 and hence the playing means will be described in detail.

The DCNT signal shown in FIGS. 11 and 12 is a slit detection signal emitted from the photocoupler 38. Further, the DCHM signal is a detection signal emitted from the detection switch 36 that detects that the movable chassis 16 is at its movement limit position, that is, the home position. As shown in FIG. 11, when there is a movement command while the photocoupler 38 is emitting the DCNT signal, the current address (current Disc) is
The movable chassis 16 is moved by a distance corresponding to the difference between the desired address (search DISC) and the desired address (search DISC). Furthermore, if a movement command is issued while the photocoupler 38 is not emitting the DCNT signal, the movable chassis 16 is moved forward (left: direction of arrow X) until the DCHM signal is emitted from the detection switch 36, and then moves to the desired address ( search DISC).

In this way, when the pushing member 41 reaches the engagement position with the tray carrying the disc 1o to be played, the motor 48
is rotated, and the pushing member 41 is rotated via the moving member 43. Therefore, as shown in FIG. 5) and FIG.
For example, the tray B12) protrudes from the case 9 of the magazine 5, and the disk 1o moves to a position concentric with the disk holding surface 52a of the turntable 52, that is, to the right side of the disk holding surface, as shown in FIG. 13(a). .

On the other hand, as the disk protrudes by the movement of the moving member 439, the moving member 43 rotates the clamper cam member 58 and the abutting member 68, respectively. As shown in FIG. 13), by the action of the cam portion 68b formed on the abutting member 68, the abutting member 68 is brought close to the suppressing member 55 of the disk clamp mechanism, and the disk 1
0 is held between the pressing member 55 and the abutting member 68. FIG. 13 (as shown in C1, +cb, after this,
Due to the action of the cam portion 68b of the abutting member 68 and the cam portion 58b of the clamper cam member 58, the disc 10 is mounted on the turntable 52 while being held by the pressing member 55 and the abutting member 68, and then the abutting member 68 is separated from the disk 10 and the suppressing member 55 pushes the disk 10
is clamped. In addition, in Fig. 13) and (C)
As shown in FIG. 2, when the disk 10 protruding outside the magazine 5 is conveyed in the horizontal direction, the disk guide pin 64 is fitted into the center hole of the disk.
The disc 10 mounted on the turntable 52 is engaged with the centering member 52b of the turntable, and is centered with respect to the center of rotation of the turntable 52 with high accuracy.

In this way, it becomes possible to play, and the turntable 52 and optical pickup (not shown) operate to start playing.

When the performance is finished, the disc 1o is stored in the magazine 5, but this disc storage operation is simply performed by following the reverse process of the disc loading operation described above, and will not be described in detail.

Thereafter, the above operation is repeated according to the specified number of songs.

Furthermore, during the above disk loading operation, the CP
The U detects the presence or absence of each magazine based on the detection signal from the detection switch 33, and if the magazine containing the desired disk is not loaded, it preferably displays this using a display means (not shown), and displays the information of the disk concerned. Searches the next specified disk without performing a search. Further, when the movable chassis 16 reaches a position corresponding to a magazine containing a disc to be played, the CPU lights only the light emitting diode 35 provided corresponding to the position. However, each light emitting diode 35 is capable of emitting light in two colors, so that all the light emitting diodes are lit in one color, and only the light emitting diodes that the movable chassis 16 reaches close to are colored in a different color. It may also be configured to emit light. Alternatively, a configuration may be adopted in which each light emitting diode is sequentially turned on as the movable chassis 16 moves, and the light emitting diode that the movable chassis 16 passes is turned off.

On the other hand, ejecting the machine 5 out of the player is done, for example, by pressing the push button 29a shown in FIG.

Effects of the Invention As detailed above, the magazine disc player according to the present invention includes a stone loading section capable of holding a plurality of magazines, each of which can accommodate a plurality of discs in an array, and a playing means guided in the direction in which the magazines are lined up. It also includes positioning means for positioning, and disk moving means for moving the disk between the magazine and the playing means, and the magazines are arranged side by side in the horizontal direction.

By arranging a plurality of magazines side by side and moving the playing means in the direction in which they are lined up, automatic playing of many discs is achieved. Since only the magazine containing the disks needs to be attached and detached, operability is improved.

Furthermore, by arranging the magazines in parallel in the horizontal direction, the entire player is horizontally elongated and the center of gravity is lower, making the player more stable.

Further, in the magazine disk player according to the present invention, each disk in the magazine is arranged so that its recording surface is vertical.

On the other hand, when the operator attaches or detaches the magazine to/from the player, the operator must grasp the flat magazine in its thickness direction. This allows the magazine to be loaded in a comfortable position, resulting in even better operability.
