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 Laid-Open No. 40563/1983.

Δ In such a disc player, the discs are arranged at narrow intervals, so replacing the discs is not always easy. In addition, it is necessary to cover the disc storage section with nozzing to protect the disc, and it is also necessary to use an opening/closing type for disc replacement. Therefore, if you want to replace some of the discs after they have been stored, you will have to remove the housing and check the disc labels one by one 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.

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

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, a plurality of locking means provided corresponding to each loading position of the magazine and locking the magazine at the insertion position; and the locking means. and eject means for releasing the magazine from the locked state, and the eject means is provided individually for each magazine.

A pad 68e made of felt or the like is attached to the contact surface with 0. Similarly, the above-described tray guide member 5
A pad 50a made of felt or the like is also attached to the contact surface with the disc 10 and the trays 11, 12 of the disc 10.

As shown in FIGS. 2, 7, and 9 (J), the movable member 43 for rotating the pushing member 41 that pushes out the cylinders 11 and 12 of the magazine 5 has not only its lower end but also its upper end. A rack portion 43c is also formed in the rack portion 43c, and a binion 75 located near the rotationally moving member 67 is meshed with this rack portion 43c.The pinion 75 is meshed with a gear portion 76a of a gear cam 76. The gear cam has a projecting portion 76b on the outer circumference, and a long hole 76c formed in the projecting portion is connected to three pins 71 implanted in the rotationally moving member 67.
It is slidably engaged with one of the two.

That is, the movable member 43 is configured to reciprocate due to the rotation of the motor 48, thereby rotating the rotary moving member 67, thereby causing the abutment member 68 to move in the horizontal direction (in the direction of arrow X and the opposite direction thereof). It is being done.

The rotational movement member 67 consists of the above-mentioned rotational movement member 67 and a series of members from the motor 48 to the gear cam 76.
The abutting member 68 is supported by a driving force applying means that applies a driving force to the drive force and peripheral small members related thereto, and the abutting member 68 is supported against the disk supporting surface of the turntable 52 (shown in FIG. 3).

On the other hand, a projecting portion 67e is formed on the outer circumference of the rotationally moving member 67, which is also formed in an arc shape, and this shaft 58f is inserted into a U-shaped notch 67f formed in the projecting portion 67e. It engages smoothly. That is, the rotational movement member 67 is configured to be provided with a rotational driving force by the above-mentioned support driving means, thereby causing the pressing member 55 to move. In this way, the number of drive sources is reduced because both the pressing member 55 and the contact member 68 are driven by one drive source.

Next, the operation of the magazine disc player having the above-mentioned structure will be briefly explained along the operating procedure with reference to FIGS. 10 to 13 (small).

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 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 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 10 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 as shown in FIG.

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. 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. As shown in FIG. 13 (C1, (d)), 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 pressing member 55 pushes the disk 10
is clamped. In addition, Fig. 13(b) and (C
), the disk 10 protrudes outside the magazine 5.
When the disc 10 is transported in the horizontal direction, the disc guide bin 64 fits into the center hole of the disc to prevent the disc 10 from slipping, and the disc 10 mounted on the turntable 52 is placed on the turntable 52. The centering member 52b is engaged with the centering member 52b, and the turntable 52 is centered with respect to the center of rotation with high precision.

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.

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 installed, it preferably displays this on a display means (not shown) and searches for the disk. The next specified disk is searched 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, the magazine 5 is ejected from the player by, for example, 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 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. The magazine has a locking means, and an ejecting means for releasing the magazine from the locking state by the stopping means, and the ejecting means is provided individually for each magazine.

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 locking means and ejecting means configured as described above, it is possible to selectively attach or detach any magazine from the player body, and when replacing a disc, only the magazine containing the disc to be replaced can be used. The disks can be attached and detached, which allows for quick disk replacement and improved operability.
