BACKGROUND ART A jukebox is generally known as a disc player that can play a plurality of discs in succession.

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

In recent years, digital audio disc (hereinafter referred to as DAI)
By recording digital signals, there are many discs that can store more information than conventional analog audio discs, and generate less noise during playback. Seeds have been developed and are widely used.

Among these, discs with an outer diameter of approximately 12 cm, which are generally called compact discs and which record and read signals using laser light, are easy to handle and allow the entire disc player to be made smaller. It is. Recently, a multi-disc player has been developed which is suitable for use as a home jukebox and is capable of storing a plurality of small DADs at all times and playing them continuously. By the way, a small DAD has a playing time of about one hour and can accommodate about 1.5 times as much 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., and a magazine that stores a plurality of discs arranged in order at a predetermined pitch and is removably attached to a predetermined mounting part in the player housing. ,

+ ). 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 about three feet rearward (in the direction opposite to the arrow Y direction) together with the magazine against the biasing force of the coil spring 59.

As a result, the detection switches 63 and 64 are activated, the motor 50 rotates, and the magazine 5 starts moving backward together with the moving member 41 and the support plate 37. Is the moving member 41 the guide 1? When the moving member moves backward a predetermined distance along the foot 34 and the rear end of the moving member comes into contact with the detection switch 65 and the detection switch operates, the motor 50 stops and the loading of the magazine 5 is completed (the first Step 82) shown in Figure 33).

Next, each operation button group 7 to 10 shown in FIG.
When a predetermined button is operated, the disc and song to be played are designated (step Sa>), and the control unit (not shown) determines whether the designated disc is stored in the magazine 5 or not. (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). The photosensor 167 confirms whether the other disk is stored (step S6), and the photosensors 67 to 69 confirm whether there is a storage section in the magazine 5 for storing the other disk (step Sy). 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. (Step Sg). If there is a storage section in the magazine 5 that can store the other disk, or if the magazine is replaced with a magazine that has a storage section, the other disk will be stored in the magazine 5 by the push-out arm 121 (see Fig. 15). (step Ss).

When it is confirmed that there is no other disk on the disk holder 85, the disk holder 85 is moved to the storage position of the designated disk 17 (step 81).
G). 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 diagram) is activated and played □
The disk 17 to be loaded protrudes out of the magazine 5 and moves onto the disk holder 85 (step Sn).

The disk protruding from the magazine 5 is the swinging lever 147.
．． 148 (shown in FIG. 15), a predetermined position (turntable 79
This is the 7th sensor 167.
Once confirmed, the motor 108 (see Figure 10)
rotates and the moving body 99 moves forward (in the direction of arrow Y),
The disk carrier 85 carrying the disk is lowered (step 5I2). In the process of the disk carrier 85 moving to its lowest position, the disk 17 on the disk carrier 85 is moved to the disk carrier surface 79 of the turntable 79.
a (shown in Figure 10) (step 513)
.

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 79, 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 constituent member of 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 514).

On the other hand, by moving the slide plate 179 to the left (in the direction of arrow X), the lever member B183 shown in FIGS. 10 and 15 rotates about the bottle 183a in the anti-Japanese sugar direction in both figures.

Then, as is clear from Fig. 15, part of the lever IJB
The bin 183e of 183 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 carrier 85, are disengaged from the outer circumference of the disk 17. Further, as the lever member 8183 rotates counterclockwise, the protruding portion 183C of the lever member moves the moving plate 170 (shown in the 10th figure) to the left (in the direction of arrow X).
Push to. 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 in the anti-Japan n1 direction in FIG.
As a result, the disk guide portion 86 is swung upward by a predetermined angle. In this way, the disc can be played, and the turntable 79 and carriage 80 (10th
(answer shown) operates and the performance begins (step S+
s>- When the performance is finished, the disc is returned to the magazine 5 (step 516), 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. I don't. However, the operation of pushing the disk 17 into the magazine 5 from above the disk carrier 85 is performed by the pushing arm 121 shown in FIG.
done by. In addition, the control section is configured such that the storage section for storing disks that should not be returned in the magazine 5 is
The photosensors 67 to 69 confirm whether or not there is one inside. 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. This notch 5b is also shown in FIGS. 2(ω, d) and (f+), and through this notch the listener can grasp the disc 17 with his or her nails and take it out of the magazine 5. However, the cutout is quite small and the listener can only grasp the outer circumference 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 the magazine is to be ejected, the lid 6 of the magazine insertion opening 3a is opened by being pushed by the ejected magazine.

Next, automatic performance means for automatically playing 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, a disc that should not be played is specified (step S6).
, this specified disc will be placed on turntable 7.
9 (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 replaced one after another (step Sx) and the last specified disk is played, the play 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 beginnings of six songs 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 841-544). If the index scan button is held down in this state, the beginnings of the six songs starting from the second song on the first disc will be played in sequence (S45~
). When the first performance of each side recorded on the first disc is completed, the first performance of each side of the second and subsequent discs is performed.

When the beginning performance of each side of all discs is completed, normal performance starts from the first disc. Also, if the RELEASE button is pressed during the beginning performance of each side, 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. Further, FIG. 38 shows that when the index scan button is pressed immediately after the beginning of a song on a given disc is played, the beginning of the song on each side of this disc is canceled and the beginning of the song on each of the following discs is canceled. 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 tenth gallebar 26 is pushed in the direction of arrow J, the protruding arm 21 resists the biasing force of the coil spring 29 to
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, thereby causing the coil spring link. The protruding arm 21, which is biased by
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 bin 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 attached to the distal end of the sub-arm 235 via a bottle 233a so as to be swingable in a plane including the up-down direction (arrow Z direction and the direction opposite thereto) and rotatably supports the corridor pressure member 192 at its free end. 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 body 233 and the sub-arm 235, a coil is provided which urges the sub-arm toward a non-clamped position (a position of the sub-arm where the suppressing member 192 attached to the sub-arm separates from the main surface of the disk 17). A spring 237 is interposed. The sub arm 235 is
By rotating an operating lever 239 rotatably provided on the arm body 233 by a pin 239a, the arm body 233 is caused to swing via a slider 240.

11 rows circle 1 As detailed 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 a turntable that sequentially selects any disc in the magazine. a disk transport mechanism that transports the disk onto the disk carrying surface of the turntable and returns the disk from the disk carrying surface into the magazine; and a clamping mechanism that clamps the disk that has been carried onto the turntable, the clamping mechanism comprising: A pressing member (192) that comes into contact with the surface of the disc to be played opposite to the turntable and cooperates with the turntable and performs a disc clamping action by the magnetic force of a magnet, and a pressing member (192) that is in a clamping position and a non-clamping position with respect to the turntable. and a support arm that is rotatable between clamp positions and rotatably supports the pressing member, and the support arm rotates along a plane parallel to the disk supporting surface of the turntable.

Therefore, compared to already developed multi-disc players in which the support arm moves in a direction approximately perpendicular to the disc supporting surface of the turntable, the overall size of the disc player can be reduced, and the height of the disc player is particularly high. This makes it easy to reduce the dimension C in the transverse direction (direction perpendicular to the disk supporting surface of the turntable).

Further, in the multi-disk play 17 according to the present invention, a non-magnetic material or nothing is arranged near the passage portion of the above-mentioned pressing member. Therefore,
The attraction force of the magnet provided on the pressing member 6 to the magnetic member does not work during the movement of the suppressing member, and the disc clamping operation is performed smoothly.
