Description

DETAILED DESCRIPTION OF THE INVENTION 1t1 The present invention relates to a disc player, and more particularly to a multi-disc player that can accommodate 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, disks with an outer diameter of about 12 CI, which are generally called compact disks and which record and read signals using laser light, are easy to handle and allow the overall size of the disk player to be miniaturized. 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 CAD has a playing time of about one 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.

Multi-disc player V 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 attachment part in the player housing. ,
A disk transport Ia system is provided for sequentially selecting arbitrary disks in the magazine, transporting them onto the disk holding surface of the turntable, and returning them from the disk holding surface into the magazine.

In a multi-disc player, when a selected disc is conveyed onto the disc-supporting surface of a turntable, two directions are used: one in a direction parallel to the disc-supporting surface and the other in a direction perpendicular thereto.
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.

0''1 The present invention has been made in view of the above-mentioned points, and its purpose is to provide a multi-disc player that can easily be downsized and cost-reduced as a whole.

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. The magazine includes a disk transport mechanism for returning the disk, a protrusion mechanism for protruding the disk out of the magazine along the main surface of the disk, and a holding mechanism for holding the disk at 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 protruding storage means for storing the disk in the magazine, 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, and the disk is placed on the disk holding surface of the turntable. and a disk moving means that moves in a direction substantially perpendicular to the magazine, and the trigger lever is provided biased to one side with respect to the direction in which the disk protrudes and is accommodated with respect to the magazine.

When the magazine 5 is pushed, the slide plate 58 provided on the lower surface of the support plate 37 moves approximately 3 mm backward (in the direction opposite to the arrow Y direction) together with the magazine against the biasing force of the coil spring 59. do. 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. Moving member 4
1 moves backward by a predetermined distance along the guide shaft 34 and the rear end of the moving member abuts the detection switch 65, and when the detection switch operates, the motor 50 stops,
Mounting of the magazine 5 is completed (step 82 shown in FIG. 33).

Next, each operation button group 7 to 1o shown in FIG.
When a predetermined button is operated to specify the disc and song to be played (step 83), 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 87). 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 specified disk 17 (step 5z).
o). 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 projects out of the magazine 5 and moves onto the disc carrier 85 (step So).

The disk protruding from the magazine 5 is the swinging lever 147.
．． 148 (shown in FIG. 15), a predetermined position (turntable 79
7), and this is the position directly above the 7 oto sensor 16.
7, the motor 108 (see FIG. 10) rotates and the movable body 99 moves forward (in the direction of arrow Y), and the disk carrying a! 185 is lowered (step 512). In the process of moving the disc holder 85 to its lowest position, the disc 17 on the disc holder is placed on the disc holder 79a (shown in FIG. 10) of the turntable 79 (step 51).
3) The forward movement of the movable body 99 continues even after the rod disk carrier 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 presses the pressing 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 pin 202, and the rotation of the tough support arm is stopped. After this, 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 disc is clamped against the main surface of the disc 7 (step 514).

On the other hand, by moving the slide plate 179 to the left (in the direction of arrow X), the lever part 0B183 shown in FIGS. 10 and 15 rotates in the counterclockwise cutting direction in both figures about the bin 183a. .

In other words, 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 carrier 85, are disengaged from the outer periphery of the disk 17. Further, by rotating the lever part 08183 in the counterclockwise direction, the protruding part 183C of the lever part moves the moving plate 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, it becomes possible to play the disc, and the seven turntables and carriage 80 (as shown in the 10th answer) operate to start playing (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. 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. Further, the control section is configured such that the storage section for storing the disks to be returned into 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 Figures 2 +a) and (Small 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 only grasps the outer periphery of the disc 17, so that the recording surface of the disc is not 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 82G).
>, the designated disc is transported 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 replaced one after another (step 826) and the last designated disk has finished playing, 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 track head detecting means that sequentially and continuously detects the track start of each side recorded on each disc in the magazine 5 for a plurality of discs. 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 of the first disc is played (
Steps 841 to 544), If the index scan button is held down in this state, the beginnings of the second and subsequent famous songs on the first disc will be played in sequence (S45).
~). 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 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.

Moreover, in the magazine 5 shown in FIG.
The disk 17 swings around the bin 21a against the biasing force of the disk 17, and the disk 17 projects out of 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 pressing 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 opposite direction thereof), and rotatably supports the pressing 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 main body 233 and the sub-arm 235, the sub-arm is placed in a non-clamped 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 coil spring 237 is interposed which biases in the direction 1. The sub-arm 235 includes an operating lever 2 rotatably provided on the arm body 233 by a pin 239a.
By rotating 39, it is caused to swing via the slider 240.

li Δ 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 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.
), and the disk transport mechanism operates the trigger lever to cause the disk to protrude outside the magazine and to store the protruded disk in the magazine. ), and a disk holding part (85) which is movable along the arrangement direction of each disk in the magazine and holds the disk protruding from the magazine by IR, and the disk is held at a substantially right angle to the disk holding surface of the turntable. and a disk moving means that moves in the same direction.

However, by simply activating the trigger lever, the disk protrudes out of the magazine by the disk protruding storage means forming a part of the disk transport mechanism, and thereby the disk is transported onto the turntable. The structure is such that movement in one of the two required directions of the disk (disk transport in a direction parallel to the disk supporting surface of the turntable) is completed. The construction of the disc protruding and storing means, which only has to perform the action of, for example, pushing 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 almost the entire disc is gripped by a complicated gripping mechanism. The configuration of the disc transport mechanism is simpler than that of a disc transport mechanism that is pulled out of the magazine, 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 trigger lever is provided so as to be biased to one side with respect to the direction in which the discs are protruded and accommodated with respect to the magazine.

Therefore, the disk protruding storage means forming a part of the disk transport mechanism is compactly arranged on the side of the disk transport path.
As a result, the space within the player housing is effectively utilized, making it easier to further downsize the disc brake 17 as a whole.
