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. 40563/1983.

In such a disc player, the discs are arranged at narrow intervals, and replacing the discs is 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 you replace some of the discs after storing them,
It is cumbersome to replace the disc by removing the housing and checking the disc labels one by one.

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.

SUMMARY OF THE INVENTION An object of the present invention is to provide a magazine disc player that can automatically play many discs, has good operability especially when changing discs, and is easy to downsize.

A magazine disc player according to the present invention includes a mounting part capable of holding a plurality of magazines each of which can accommodate a plurality of discs in an array, a positioning means for guiding and positioning a playing means in the direction in which the magazines are lined up, and a disc moving means for moving the disc between the playing means, and each magazine is lined up with a plurality of locking means provided corresponding to each loading position of the magazine and locking the magazine at the insertion position. The present invention is characterized by having a single ejecting means that is movable in the direction and releasing the magazine from the locked state by the locking means, and an ejecting means positioning means that positions the ejecting means.

Further, the above-mentioned guide driving means for moving the movable chassis 16 and the playing means position detecting means constitute a positioning means for positioning the playing means in the direction in which the magazines 5 are arranged.

FIG. 13 shows a modification of the above-mentioned performance means position detection means. As shown in FIG. 13, a slit 83c is formed in the detected member 83 having light shielding portions 83a and 83b, corresponding to the intermediate position of each disk storage position in the magazine 5. As shown in FIG. Two photocouplers 87a and 87b are arranged corresponding to this slit 83C, and together with other photocoupler 84a to 84c, movable chassis 16
is attached to. That is, when the optical axis centers of the two photocouplers 87a and 87b respectively coincide with the slits 83c, the position of the disc is determined, and thereby the storage position of the disc can be searched with high precision.

Next, the operation of the magazine disc player having the above-mentioned structure will be briefly explained along the operating procedure with reference to the songs in FIGS. 15 to 18.

First, when a disc to be played is specified by operating the operating section 3 shown in FIGS. 1 and 15, 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 chassis 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 signals shown in FIGS. 16 and 17 are detection signals emitted from the photocouplers 84a to 84c. Further, the DCHM signal is a detection signal emitted from the detection switch 86 that detects that the movable chassis 16 is at its movement limit position, that is, the home position. 16th
As shown in the figure, photocouplers 84a to 84c are DC
If a movement command is issued while the NT signal is being issued, the movable chassis 16 is moved by a distance corresponding to the difference between the current address (current MAG: magazine) and the desired address (search MAG). In addition, photocouplers 84a to 84c
If a movement command is issued while the DCNT signal is not being emitted, the movable chassis 16 is moved forward (left: direction of arrow X) until the DCHM signal is emitted from the detection switch 86, and then moves to the desired address (search MAG) position. be moved to

Next, the movable chassis 16 is slightly moved to a position corresponding to the target disk.

In this way, when the pushing member 41 reaches the engagement position with the tray carrying the disc 10 to be played, the motor 48
is rotated, and the extrusion member 4] is rotated via the moving member 43. Therefore, as shown in FIG.
For example, the tray B12) protrudes from the case 9 of the magazine 5, and the disk 10 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. 18(a). .

On the other hand, as the disk protrudes by the movement of the moving member 43, the moving member 43 rotates the clamper cam member 58 and the abutting member 68, respectively. As shown in FIG. It is held between the contact members 68.

Subsequently, as shown in Figure 18 (C1, (small), 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, Figure 18 songs) 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 member 81 comes into sliding contact with the lower end of the disk 10, and the insertion pin 55a of the pressing member 55 fits into the center hole of the disk. This prevents the disc 10 from shifting in the radial direction, and when the disc 10 is mounted on the turntable 52, the centering part 52b of the turntable is aligned with the recess 5 of the pressing member 55.
By engaging with 5b, the turntable 52 is centered with respect to the center of rotation with high precision. Thereafter, the disk guide member 81 is separated from the disk 10 as shown in FIG. 18 (small).

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 10 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.

Incidentally, the magazine 5 is ejected from the player by pressing an eject button included in the operating section 3 shown in FIG. At this time, when the magazine to be ejected is specified by operating the operation section 3, the photocoupler 28d and address play 29h shown in FIGS. 2 to 4, and the detection switch 28e are activated.
A desired magazine is searched for and the solenoid plunger 30 serving as ejecting means is moved to the engagement position with the locking pawl member 27 that locks the magazine. The positioning of the solenoid plunger 30 is performed in the same manner as the positioning of the movable chassis 16 described above, and therefore will not be described in detail.

Effects of the Invention As detailed above, the magazine disc player according to the present invention includes a mounting part 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. and a plurality of disk moving means for moving the disk between the magazine and the playing means, the plurality of disk moving means being provided corresponding to each loading position of the magazine and locking the magazine at the insertion position. a single eject means that is movable in the direction in which the magazines are lined up and releases the magazine from being locked by the locking means, and an eject means positioning means that positions the eject means. .

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, and when a disc needs to be replaced, it is possible to The operability is good because only the stored magazine needs to be attached and detached.

Furthermore, since it has the above-mentioned locking means, ejecting means, and ejecting means positioning means, it is possible to selectively attach or detach any magazine from the player body, and when replacing the disc, it is possible to store the disc to be replaced. Only the magazine can be attached and detached, which allows for quick disk replacement and even better operability.
