Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disc player, and more particularly to a multi-disc player that can store a plurality of discs and can sequentially select any of the stored discs for continuous play.

A jukebox is generally known as a disc player that can play multiple discs in succession.

However, conventional jukeboxes have very large bodies, making them unsuitable for home use.

In recent years, it has been called a digital audio disc (hereinafter abbreviated as DAD), and by recording digital signals, it is possible to increase the amount of information that can be stored compared to the conventional audio disc that contains analog signals, and it is easier to play. Several types of disks that generate less noise have been developed and are widely used.

Among these, discs with an outer diameter of approximately 12□□□, which are generally called compact discs and which record and read signals using laser light, are easy to handle and allow the overall size of the disc player to be made smaller. That is. Recently, multiple pieces of this small DAD can be stored at all times.
A multi-disc player that is suitable for use as a home jukebox and can play these discs continuously has been developed.

By the way, a small DAC has a playing time of about 1 hour and can accommodate about 1.5 times the amount of information as a conventional analog audio disc. Therefore, for example, three discs can accommodate approximately 60 songs with a performance time of around 3 minutes, and it is easy to cover favorite songs by genre, such as jazz or enka.

A multi-disc player basically consists of a playing means including a turntable, a pickup, etc., a magazine in which a plurality of discs are sequentially arranged and stored at a predetermined pitch, and is removably attached to a predetermined attachment part in the player housing.
The apparatus includes a disk transport mechanism that sequentially selects arbitrary disks in the magazine, transports them onto the disk holding surface of the turntable, and returns them into the magazine from the disk holding surface.

In a multi-disc player, when a selected disc is conveyed onto the disc-supporting surface of a turntable, two directions are used: one parallel to the disc-supporting surface and the other perpendicular to the disc-supporting surface.
Moving the disk in the direction is performed. However, in the multi-disc players that have already been developed, the disk conveyance mechanism for carrying out this conveyance directly grips the desired disk in the magazine, the end of the disk in the direction in which the disk protrudes from the magazine, or almost the entire disk. The structure of the disk transport mechanism, including the gripping mechanism that grips the disk, is complex and large, and the space required for its operation is large, making it difficult to use as a whole for the disk player. It is difficult to miniaturize the device, and it also increases costs.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned points, and its purpose is to easily reduce the size and cost of the entire disc player, and to provide a multi-purpose disc player that facilitates the smooth transportation of discs. To provide a disc player.

A multi-disc player according to the present invention includes a magazine that sequentially arranges and stores a plurality of discs, and sequentially selects and transports arbitrary discs in the magazine onto a disc-carrying surface of a turntable, and transports the discs from the disc-carrying surface onto the magazine. a disk transporter for returning the disk, the magazine includes a protruding mechanism for protruding the disk out of the magazine along the main surface of the disk, and a holding mechanism for holding the disk in the storage position. and a trigger lever for actuating the ejection mechanism and the holding mechanism from outside the magazine, and the disk transport mechanism activates the trigger lever to eject the disk to the outside of the magazine and to remove the ejected disk. A disk holding surface of the turntable includes a disk protruding storage means for storing the disk in the magazine labeled F, and a disk holding part that is movable along the arrangement direction of the disks in the magazine and supports the disk protruding from the magazine. a disk moving means that moves in a direction substantially perpendicular to the magazine; and detecting that the disk holding section has reached a position where it can support any disk protruding outside the magazine, and stopping the disk holding section.

The apparatus includes a confirmation means, and a music head detecting means that successively detects the beginning of each picture recorded on a disc sequentially and continuously for a plurality of discs (for example, three discs).

Next, the operation of the multi-disc player configured as described above will be briefly explained along the playing procedure with reference to FIGS. 33 to 38.

First, as shown in FIG. 1, insert the magazine 5 from the magazine insertion port 3a (step S in FIG. 33).
+ ). First, the magazine 5 is supported on the support plate 37 shown in FIGS. 7 to 9. In this state, press the magazine 5 a little forcefully. When the magazine 5 is pushed, a slide plate 58 provided on the lower surface of the support plate 37 moves rearward (in the opposite direction of arrow Y) together with the magazine by about 3 seconds against the biasing force of the coil spring 59.

As a result, the detection switches 63 and 64 are operated, the motor 50 rotates, and the magazine 5 starts moving backward together with the moving member 41 and the support plate 37. When the movable member 41 moves backward by a predetermined distance along the guide shaft 34 and the rear end of the movable member contacts the detection switch 65 and the detection switch operates, the motor 50 stops and the magazine 5 is loaded. is completed (step 3 shown in Figure 33).
2).

Next, each operation button group 7 to 10 shown in FIG.
When a predetermined button is operated to specify the disc and song to be played (step S3), the control section (not shown) determines whether or not the designated disc is stored in the magazine 5. (Step 84)
). This confirmation is performed by photosensors 67 to 69. If the specified disk is not in the magazine 5, this is notified to the listener by an alarm, and the magazine is ejected to prompt replacement of the magazine 5 (step Ss). When it is confirmed that the specified disk is stored in the magazine 5, the control section controls whether another disk is supported on the disk holding section 85 (this disk holding section is called a tray in the flowchart). It is confirmed by the photosensor 167 whether the lumbosacral disc is stored (step S6), and it is also confirmed by the photosensors 67 to 69 whether there is a storage section in the magazine 5 for storing the lumbosacral disc (step S7). If there is another disk on the disk holding section 85 (tray) and there is no storage section in the magazine 5 that can accommodate this disk, the magazine is ejected to prompt replacement of the magazine 5, and an alarm is activated. The listener is informed (step Ss). If there is a storage section in the magazine 5 that can accommodate the other disks mentioned above, or if the magazine is replaced with a magazine that has a storage section, the lumbosacral disk will be stored in the magazine 5 by the push-out arm 121 (see Figure 15). (step Ss).

When it is confirmed that there is no other disk on the disk carrier 85, the disk carrier 85 is moved to the storage position of the designated disk 17 (step 81).
0). The disk holder 85 is stopped at the designated disk storage position by the photosensors 162 and 212. When the disk holding part 85 stops, the actuating rod 112 (see FIG. 15, etc.) is projected to the right (in the direction opposite to the arrow X), thereby causing the trigger lever 2 in the magazine 5 to
6 (shown in the third figure) is activated, and the disc 17 to be played is projected out of the magazine 5 and moved onto the disc carrier 85 (step 511).

The disk protruding from the magazine 5 is the swinging lever 147.
．． 148 (shown in FIG. 15), a predetermined position (turntable 79
), and this is the photo sensor 16
7, the motor 108 (see FIG. 10) rotates, the movable body 99 moves forward (in the direction of arrow Y), and the disk carrier 85 carrying the disk is lowered (step 512). In the process of moving the disc carrier 85 to its lowest position, the disc 17 on the disc carrier 85 is moved to the disc carrier surface 79 of the turntable 79.
Step 5L3)
.

The forward movement of the movable body 99 continues even after the disk holding part 85 reaches its lowest position, thereby causing the first
The lever member A176 shown in FIG. 0 is rotated counterclockwise in FIG. 10 for the first time. Therefore, the slide plate 179 connected to this lever member A176
moves to the left (in the direction of arrow X), and the clamp mechanism is activated.

The operation of this clamp mechanism will be explained in some detail.

By moving the slide plate 179 to the left (in the direction of arrow X), the support arm 198 of the clamp mechanism first moves.
rotates about the rotation support shaft 187, for example, in the counterclockwise direction in FIG.

The support arm 198 rotates by a predetermined angle and the suppressing member 19
2 reaches directly above the turntable 7, the adjustment screw 201 provided on the support arm (the arm body 189, which is a component thereof) engages with the bin 202, and the rotation of the support arm is stopped. This model, slide plate 179
is driven further to the left, thereby causing support arm 19
A rotating lever 196, which is a component of the arm 8, rotates around the bin 196a, and therefore a slide plate 194 connected to the rotating lever moves along the arm body 189. Therefore, as is clear from FIG. 13, the sub-arm 190 swings downward, and the pressing member 192 pushes the disk 1
The disk is clamped against the main surface of 7 (step 814).

On the other hand, as the slide plate 179 moves to the left (in the direction of arrow X), the lever member B183 shown in FIGS. 10 and 15 rotates counterclockwise in both figures about the bin 183a.

Then, as is clear from FIG. 15, the lever member B1
83 bin 183e engages with the interlocking lever 149 to move the interlocking lever forward (in the direction of arrow Y). Therefore,
The swing levers 147 and 148, which were positioning the disk 17 on the disk holder 85, are disengaged from the outer periphery of the disk 17. Further, by rotating the lever member 8183 in the counterclockwise direction, the protruding portion 183C of the lever member moves the moving plate t-170<shown in the 10th figure to the left (in the direction of the arrow X).
Press. Therefore, the other swinging lever 1 shown in FIG.
55 separates from the outer circumference of the disk. Also, by moving the moving plate 170 to the left, FIGS.
The lifting lever 171 shown in FIG. 5 rotates counterclockwise in FIG. 11 about the bin 171a, thereby causing the disk guide member 86 to swing upward by a predetermined angle. In this way, the disc can be played, and the turntable 79 and carriage 80 (see FIG. 10) are operated to start playing (step 515).
.

When the performance is finished, the disc is returned to the magazine 5 (step 816), but since the operation of returning the disc to the magazine 5 is almost the reverse of the disc loading operation described above, it will not be described in detail. However, the operation of pushing the disk 17 into the magazine 5 from above the disk holder 85 is carried out by the pushing arm 121 shown in FIG.
done by. Further, the control section is configured such that the storage section for storing the disks to be returned into the magazine 5 is
It is confirmed by the 7 sensors 67 to 69 whether or not there is. As shown in FIG.
When the push-out arm is in the push-out position to push out the disk 17, the tip of the push-out arm seems to come into contact with the magazine 5, but since the magazine 5 has a notch 5b formed in this part, the movement of the push-out arm is limited. not be hindered. Fig. 2 +a+, (d+ and +f+ also have this notch 5b.
is shown, the listener can grasp the disc 17 with his or her fingernails and take it out of the magazine 5 through the notch. However, the cutout is quite small, and the listener can only grasp the outer periphery of the disc 17, so the recording surface of the disc will not be damaged by the listener's fingernails.

Thereafter, the above operation is repeated depending on the specified disk. Also, in order to replace magazine 5,
When ejecting the magazine, the lid 6 of the magazine insertion opening 3a is opened by being pushed by the ejected magazine.

Next, automatic performance means for automatically performing a performance sequence including at least two discs unless a stop command is issued will be described. FIG. 34 shows a case where this automatic performance means is operated manually. First, the disc to be played is specified (step 820).
), the designated disc is conveyed onto the turntable 79 (step 521). Then, the performance starts from the beginning of the disc (step 522), and when the performance ends, it is replaced with the next disc. When the disks are sequentially replaced (step 526) and the last designated disk has finished playing, the playing starts again from the first disk. If the stop button is pressed during this continuous performance, the performance ends.

Incidentally, FIG. 35 shows the operation of the automatic performance means when the number of songs is programmed.

FIG. 36 is a diagram illustrating a song head detecting means that sequentially detects the beginning of a famous piece of music recorded on each disk in the magazine 5 and continuously for a plurality of disks. First, when the index scan button (any one of the operation button groups 7 to 10), which is a so-called lock button, is pressed, the button is locked in the pressed state. Then, the number X of the disc to be index scanned is set to 1, and the beginning of the first track on the first disc is played (
Steps 341-544). If the index scan button is held down in this state, the beginnings of famous songs starting from the second track on the first disc will be played in sequence (from 845 to
). When the opening performance of the famous song recorded on the first disc is completed, the opening performance of the famous song is performed on the second and subsequent discs.

When the opening performance of the famous songs on all discs is completed, the normal performance starts from the first disc. Also, if the RELEASE button is pressed during the beginning performance of a famous song, the normal performance is resumed.

FIGS. 37 and 38 are for explaining modifications of the curve head detection means. FIG. 37 shows that when the index scan button is pressed immediately after the beginning of a certain song on a predetermined disc is played, the beginning of the next song immediately starts playing. In addition, FIG. 38 shows that when the index scan button is pressed immediately after the beginning of a certain song on a given disc is played, the beginning of the famous song on this disc is canceled and the first song of each next disc is played. This indicates that the beginnings of the songs will be performed in sequence.

39 to 42 show modified examples of the internal structure of the magazine 5. FIG.

In the magazine 5 shown in FIG. 39, when the trigger lever 26 is pushed in the direction of arrow J, the protruding arm 21 resists the biasing force of the coil spring 29 and moves the pin 2.
The disk 17 is pushed out of the magazine 5 by swinging about 1a.

In the magazine 5 shown in FIG. 40, when the trigger lever 26 is pushed in the direction of the arrow J, the intermediate lever 221 rotates about the pin 221a against the tension of the coil spring 222. The protruding arm 21, which is biased by the pin 223, swings around the pin 21a, and
protrudes to the outside of the magazine 5.

Furthermore, in the magazine 5 shown in FIG. 41, by pulling the wire 226 as a trigger lever in the direction of the arrow, the protruding arm 21 swings about the pin 21a against the biasing force of the coil spring 227. , the disk 17 protrudes outside the magazine 5.

In the magazine 5 shown in FIG.
7 in the direction of the arrow against the biasing force of the coil spring 228, the disk 17 is projected out of the magazine 5 by the wire.

In addition, in the multi-disc player mentioned above, the first
As shown in FIG. 6, etc., the clamp mechanism is configured such that the suppression member 192 moves parallel to the disk supporting surface of the turntable 79 by rotation of the support arm 198, but the present invention is not limited to this configuration. . Another embodiment of the clamping mechanism is shown in FIGS. 43 and 44. As shown in the figure, a guide shaft 231 is provided that extends parallel to the disk supporting surface 79a of the turntable 79, and the support arm 232 includes an arm body 233 that slides on the guide shaft, and an arm body 233 that slides on the guide shaft. A sub-arm 235 is swingably attached to the tip via a pin 233a in a plane including the up-down direction (arrow 7 direction and the opposite direction), and rotatably supports the suppressing member 192 at its free end. It consists of A rack portion 233b is formed in the arm body 233 along the direction of movement thereof, and the arm body is driven by a drive source including a gear 236 that meshes with the rack portion 233b.

Further, between the arm main body 233 and the sub-arm 235, a coil 9A is attached so that the sub-arm is in an unclamped position (a position of the sub-arm where the pressing member 192 attached to the sub-arm is separated from the main surface of the disk 17). A spring 237 is interposed. The sub-arm 235 is operated by rotating an operating lever 239 rotatably provided on the arm body 233 by a pin 239a.
It is made to swing via a slider 240.

As described in detail above, the multi-disc player according to the present invention includes a magazine (5) that sequentially arranges and stores a plurality of discs (17), and an arbitrary disc in the magazine that is sequentially selected and placed on the turntable. a disk conveying mechanism for conveying the disk onto a disk carrying surface and returning the disk from the disk carrying surface into the magazine, the magazine having a mechanism for causing the disk to protrude out of the magazine along the main surface of the disk; Projection mechanism (projection arm 21
), a holding mechanism (holding arm 24) for holding the disk in the storage position, and a trigger lever (26) for operating the protruding mechanism and holding mechanism from outside the magazine.
), the disk transport mechanism has a disk protruding and storing means (comprised of an actuating rod 112, etc.) for actuating the trigger lever to cause the disk to protrude out of the magazine and to accommodate the protruded disk in the magazine. ,
It includes a disk holding part (85) that is movable along the arrangement direction of each disk in the magazine and supports a disk protruding from the magazine, and moves the disk in a direction substantially perpendicular to the disk holding surface of the turntable. and a disk moving means.

That is, by simply actuating the trigger lever by the disk protruding and storing means forming a part of the disk transport is, the disk protrudes out of the magazine, thereby allowing the disk to be moved out of the magazine. The structure is such that movement vJ (disk conveyance in a direction parallel to the disk supporting surface of the turnchill) in one of the two directions of the disk is completed. The structure of the disk protruding and storing means, which only has to act by pressing the trigger lever, is extremely simple and compact. Therefore, in a multi-disc player that has already been developed, a desired disc stored in a magazine is directly gripped by the end of the disc in the direction of protrusion from the magazine or by approximately the entire disc using a complicated gripping mechanism. The configuration of the disc transport mechanism is simpler than that of a disc transport mechanism that can be pulled out, making it easier to downsize the disc player as a whole and reducing costs.

Further, in the multi-disc player according to the present invention, the disk transport mechanism stops the disk carrying section upon detecting that the disk carrying section has reached a position where it can carry any disk protruding outside the magazine. The disk protruding storage means is provided on the disk holding part and is reciprocally movable in a predetermined direction, and its reciprocating movement causes the trigger lever (2
6), and an actuating rod (112) which is swingable between an extrusion position and a non-extrusion position, and which presses the outer periphery of the disk with its free end to extrude the disk from above the disk holder. It has an extrusion arm (121) for storing in the magazine, and a drive source for driving the operating rod and the extrusion arm, and the position detection means includes a plurality of extrusion arms (121) provided in the magazine along the disk arrangement direction. marks (reflectors 161a to 161c), and a sensor (attached to the disc holder to detect each mark).
a photosensor 162) located in close proximity to the actuating rod.

The sensor (photo sensor 162) and the actuating rod (112) are both provided on the disk holder (85).
However, let us consider a case where they are placed quite apart. Due to manufacturing errors in the disk holding part (85), bending due to its own weight, or distortion due to thermal expansion, etc.
It is conceivable that the sensor and the actuating rod may be relatively displaced from their normal installation positions, and the amount of this displacement increases as the distance between the sensor and the actuating rod increases. As a result, even if the disk holding part (85) is accurately stopped relative to the magazine by the action of the sensor and mark, the position of the actuating rod does not correspond to the position of the trigger lever, resulting in the worst case. In this case, a problem may occur in which the disk cannot be ejected from the magazine.

In the multi-disc player according to the present invention, since the sensor and the operating rod are provided close to each other, such a problem does not occur, and the discs are transported smoothly.
