Description

BACKGROUND OF THE INVENTION 1. Field of the Invention 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 is so large that it is not suitable for home use.

In recent years, it has been called a digital audio disc (hereinafter abbreviated as DAD), and by recording a digital signal, the amount of information to be stored can be increased as compared with a conventional analog signal-added audio disc, and reproduction can be performed. Several types of discs have been developed and are widely used, which generate less noise. Among them, a disc having an outer diameter of about 12 cm, which is generally called a compact disc by a method of recording and reading a signal by using a laser beam, is easy to handle and enables downsizing of the entire disc player. is there. Recently, multiple small DADs (for example, 5
(~ 6 sheets), a multi-disc player has been developed which can be always stored and is optimal as a home jukebox that continuously plays these. By the way, the compact DAD has a playing time of one hour, and can store about 1.5 times as much information as a conventional analog audio disk. for that reason,
For example, six discs can accommodate about 120 songs if the playing time is about 3 minutes, and it is easy to cover the genres of interest such as jazz or enka.

The multi-disc player basically has a playing means including a turntable, a pickup, etc., a disc holder which holds the disc and is inserted and mounted in a mounting portion in the player housing, a playing position of the disc in the disc holder, That is, it is provided with a disc take-out and transport mechanism for transporting the disc onto the turntable.

In the multi-disc player, when the disc in the disc holder is conveyed onto the turntable, for example, the disc is moved in two directions, a direction parallel to the disc carrying surface of the turntable and a direction 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.

To solve this problem, recently, for example, Japanese Patent Application No. 60-1
As proposed as 04310, the disc holders may be arranged in a housing and in the housing in a direction substantially perpendicular to the disc-carrying surface of the turntable to carry a disc on each major surface and to the housing. On the other hand, a multi-disc player has been newly developed that is configured by a plurality of plate-shaped trays that can be projected and stored along each main surface. 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, as in the above-mentioned multi-disc player, the disc housed in the disc holder is directly held outside the disc holder by directly grasping the end portion of the disc in the protruding direction from the disc holder or substantially the entire disc by a complicated grasping mechanism. The structure is simpler than that of the one provided with a disc ejecting / conveying mechanism of a pull-out type, and it is easy to reduce the size and cost of the player as a whole.

As a specific structure of the disc take-out and transport mechanism for feeding the disc in two directions, a tray projecting means for projecting the tray carrying the disc to be played from the housing of the disc holder, and a tray projecting outside the housing. Disk moving means for moving the disk carried thereon in a direction substantially perpendicular to the disk carrying surface of the turntable, wherein the tray projecting means comprises a supporting member extending along the arrangement direction of the trays. A moving member movably provided in the supporting member in the arranging direction and carrying playing means (turn tail, pickup, etc.); and one of the trays movably provided on the moving member in a predetermined direction. A tray projecting member that engages with each other to project the tray out of the housing of the disc holder, Tray protruding member moving means for moving the tray protruding member together with the moving member to a position for engaging the tray carrying the disc to be driven, and tray protruding member driving for driving the tray protruding member to protrude the tray from the housing. And means.

That is, by moving the entire playing means including the turntable and the pickup along with the moving member carrying the playing means along the arrangement direction of the trays, the relative movement of the trays and the turntable in the tray arrangement direction. By moving the tray projecting member and moving the tray projecting member, each tray is pushed to project each tray out of the housing of the disc holder and the disc on the tray is turned. It is structured so that it can be located directly under the table.

SUMMARY OF THE INVENTION It is an object of the present invention to provide such a multi-disc player, particularly a multi-disc player having good vibration resistance with respect to playing means including a turntable and the like.

The multi-disc player according to the present invention is a lock that locks a moving member, which is movably provided in a tray arranging direction with respect to a predetermined supporting member, and carries a playing means, to the supporting member when a disc is being played.

The presence / absence of a disc is detected by detecting the numbers 45 and 146.

Next, the operation of the multi-disc player having the above-mentioned structure will be briefly described along the playing procedure with reference to FIGS. 28 to 32.

First, when a disc to be played is designated by operating the operation button group 6 shown in FIG. 1, a drive voltage is supplied to the motor 45, and the moving plates 37 and 38 are moved forward (in the direction of arrow Y) or The movement starts backward (in the direction opposite to the arrow Y). Therefore, by the action of the stepped cam grooves 37d and 38d formed in the moving plates 37 and 38 and the guide groove 16e formed in the chassis 16, the pin 20c movably fitted in each groove moves up and down. The moving member 18 including the movable chassis B20 on which the pin 20c is provided is vertically moved. Therefore, the tray projecting member 53 provided on the moving member 18 reaches the engagement position with the tray 11 or 12 carrying the disc to be played.

Here, the front and rear movement and positioning of the moving plate 37,
Therefore, the vertical movement and positioning of the tray protruding member 53 will be described in detail.

The DCNT signal shown in FIGS. 28 and 29 is a slit detection signal emitted from the photo sensor 51. Further, the DCHM signal is a detection signal emitted from the detection switch 49 for detecting that the moving plate 37 is at the most returning position (forward movement limit position), that is, the home position. As shown in FIG. 28, when the photo sensor 51 is issuing a DCNT signal and there is a movement command, the movement plate 37 is moved by a distance corresponding to the difference between the current address (current DISC) and the desired address (search DISC). Can be moved. In addition, the photo sensor 51 is DCN
If there is a movement command when the T signal is not issued, the movement plate 37 is moved back (moved forward) until the detection switch 49 issues the DCHM signal, and then moves to the position of the desired address (search DISC). Be punished.

Thus, when the tray protruding member 53 is positioned at the engagement position with the tray carrying the disc to be played,
Next, the motor 62 starts rotating, and the moving body 56 is driven backward (in the direction of the opposite arrow Y). Therefore, the intermediate lever 70 is rotated in the counterclockwise direction in FIG. 10, and the second lever member 72 connected to the intermediate lever moves to the right (counter arrow X direction). As shown in FIG. 20, the second lever member 72 is in the locked state with the first lever member 71 by the lock / release means composed of the movable piece 76 and the like. Therefore, the first lever member 71 also moves rightward together with the second lever member 72, whereby the tray protruding member 53 rotates, for example, in the clockwise direction in FIG. Therefore,
As shown in FIG. 2 (b), a tray (for example, tray B12) carrying a disk to be played protrudes from the magazine body 8, and the disk is a disk carrying surface 23a of the turntable 23 (see FIG. 11 (b)). ) With respect to (a), that is, immediately below the disk carrying surface. However, immediately before the rotation of the tray projecting member 53, and thus the movement of the first lever member 71 to the right, is completed,
The lock state of the first and second lever members 71, 72 by the releasing means is released, and the subsequent slight rightward movement of the first lever member 71 causes a coil spring 75 (see FIG. 20, etc.).
Positioning of the tray is completed by the arcuate portion 12n (see FIG. 2 (b)) of the tray B12 that is pushed by the biasing force of To do. In addition,
Completion of the ejection of the tray from the magazine body 8 is detected by a detection signal from a detection switch 87 (see FIG. 8 and the like) operated by the movement of the moving body 56. Also, tray B
Before the tray protrudes from the magazine body 8, the flexible shift preventing projections 12j and the like formed on the sheet 12 are in the state shown in FIG.

The second lever member 72 released from the locked state with the first lever member is further driven to the right (counter arrow X direction), and the pin 7 is attached to the tapered portion 72f (shown in FIG. 20) of the second lever member.
Clamping mechanism support 79 engaged by 9c
(10th illustration) rock | fluctuates upwards (arrow Z direction). Therefore, the disc is lifted up and clamped to the turntable 23 (state shown in FIG. 31). The upward movement of this disc is shown as DISC load in FIG. Further, with the upward movement of the disc, the disc pressing member 83 also rises together with the disc due to the rotation of the intermediate lever 70. However, when the loading of the disc on the turntable is completed, the disc pressing member 83 is slightly separated from the disc, and the disc pressing member does not hinder the rotation of the disc.

Here, the roller 111 shown in FIGS. 24 and 31 is used.
The operation of the lever member 112 and the like will be described in detail.

When the tray B12 projects from the magazine body 8, the roller 111 rotates while contacting the main surface of the disk 10 on the tray by the urging force of the coil springs 115 and 116. When the tray B12 is completely projected, the disc 10 is positioned immediately below the turntable 23, and thereafter, the disc is moved upward by the clamp mechanism as described above. With the upward movement of the disc, the lever member is moved. Since 112 swings upward, the contact state of the roller 111 with the main disk surface is maintained. At the same time when the disc is clamped, the other lever member 113 is swung, for example, in the clockwise direction in FIG. 31, and the protrusion 113b formed on the lever member engages with the protrusion 112b of the lever member 112, so that the lever The member 112 is further swung clockwise by a predetermined angle. As a result, the roller 111 separates from the main surface of the disc 10. As mentioned above,
The swinging of the lever member 113 is performed by the second lever member 72 (10th
(See the drawings, etc.).

On the other hand, as shown in FIG. 32, the rotation of the intermediate lever 70 causes the relay lever 132 to swing counterclockwise in FIG. 32 by a predetermined angle. Relay lever 13
The swinging of No. 2 is performed by the rotation of the intermediate lever 70 only at the initial movement, and the swinging operation thereafter is due to the urging force of the spring member 134. The swing of the relay lever 132 causes the first branch portion 132b of the relay lever to engage with the pin 122c of the slider 122 and push the slider to the left (direction of arrow X), whereby the other sliders 121 and 123 ( (The 25th illustration) also moves. Therefore, the locking pin 125 provided at the end of each slider fits into the locking hole 16g (shown in FIG. 25) formed in the chassis 16 as a supporting member, and thus the moving member 18 including the movable chassis B20 is inserted. The whole chassis 16
Locked against.

Thus, the performance becomes possible, and the turntable 23 and the carriage 24 (see FIG. 9 and the like) operate to start the performance.

When the performance is finished, the disc is stored in the magazine main body 8. However, 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 number of songs.

The eject operation of the magazine 5 to the outside of the player body is performed by pressing the magazine eject button of the operation button group 6. When the magazine eject button is pressed, the movable body 56 (see, for example, FIG. 19) is moved forward (in the direction of arrow Y) by a predetermined amount, whereby the locked state of the magazine 5 by the lock member 67 is released. As a result, the swing lever 64 shown in FIG. 10 swings around the pin 64a, and the magazine 5 engaged with the free end of the swing lever is pushed out of the player body.

As described above in detail, in the multi-disc player according to the present invention, the moving member, which is provided so as to be movable in the tray arranging direction with respect to the predetermined supporting member (chassis 16), carries the playing means including the turntable and the like. Locking means (comprising a locking pin 125, etc.) for locking (18) with respect to the supporting member when the disc is being played.
Is provided.

Therefore, even if the multi-disc player receives a relatively large force from the outside while the disc is playing, the moving member does not vibrate greatly. That is, it has good vibration resistance with respect to the playing means, and is suitable for, for example, on-vehicle use.
