The above-mentioned control section also includes an eject means that issues a magazine eject operation command even during disc play in response to a manual eject command, and an eject means that stores the disc when the disc is returned from the disc holding part 85 into the magazine 5. A storage unit confirmation means for checking whether or not a storage unit exists in the magazine 5; and a storage unit confirmation means for checking whether or not a storage unit is present in the magazine 5; and checking means for checking whether there is a storage section in the magazine 5 for storing the other disk.

The control unit also includes an automatic performance means for automatically playing a performance sequence including at least two discs unless a stop command is received, and a disc for checking whether a designated disc is stored in the magazine 5 or not. The apparatus includes a presence/absence confirmation means and a music head detection means for sequentially and continuously detecting the beginning of a famous piece of music recorded on a disc on a plurality of discs (for example, three discs).

Next, the operation of the multi-disc player having the above-described structure 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 S shown in FIG.
z).

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 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 designated 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 above! , IJ til1 uses the photosensor 167 to check whether another disk is being held on the disk holding section 85 (this disk holding section is referred to as a tray in the flowchart). i! (Step S6), and
It is confirmed by the photosensors 67 to 69 whether or not there is a storage section in the magazine 5 for storing the other disk (
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 Sa). If there is a storage section in the magazine 5 that can accommodate the other disk, or if a magazine with a storage section is replaced, the other disk will be stored in the magazine 5 by the push-out arm 121 (see FIG. 10). (step 89).

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 5e).
a). 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 Sn).

The disk protruding from the magazine 5 is the swinging lever 147.
, 148, etc. (shown in Figure 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, 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.
a (shown in Figure 10) (step 5L3)
.

Even after the disk carrier 1185 reaches its lowest position, the moving body 99 continues to move forward, causing the lever member Al 76 shown in FIG. 10 to rotate counterclockwise in FIG. 10 for the first time. Can be set. 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 set on the support arm (the arm body 189, which is a component thereof) engages with the pin 202, and the rotation of the support arm is stopped. It will be done. After this, slide plate 17
9 is further driven to the left, thereby causing the pivot lever 196, which is a component of the support arm 198, to move towards the bin 196.
The slide plate 194 rotates around a, and therefore, the slide plate 194 connected to the rotation lever moves along the arm body 189. Therefore, as is clear from FIG. 13, the sub-arm 190 swings downward, the pressing member 192 comes into contact with the main surface of the disk 17, and the disk is clamped (
step 314).

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 1830 engages with the interlocking lever 149 to move the interlocking lever forward (in the direction of arrow Y). Therefore,
The swinging levers 147 and 148, which were positioning the disk 17 on the disk carrier 85, disengage from the outer circumference of the disk 17. Furthermore, as the lever member 8183 rotates counterclockwise, the protruding portion 183C of the lever member pushes the moving plate 170 (shown in the 10th figure) to the left (in the direction of the arrow X). Therefore, the other swinging lever 15 shown in FIG.
5 separates from the outer periphery of the disk. Also, by moving the moving plate 170 to the left, FIGS. 11 and 15
The lifting lever 171 shown in the figure rotates counterclockwise in FIG. 11 about the bin 171a, thereby swinging the disk guide member 86 upward by a predetermined angle. In this way, the disc can be played,
The turntable 79 and carriage 80 (10th equivalent illustration) operate to start playing (step S+s).

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, we will not discuss it in detail. stomach. 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 FIGS. However, the notch 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 a magazine, the lid 6 of the magazine insertion slot 3a is pressed 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 Sn)
, 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 528) and the last designated disk has finished playing, the playback 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 each side of the second and subsequent tracks of the first disc will be played in sequence (from 845 to
). When the first song on each side recorded on the first disc is finished, the first 8 songs on each side recorded on the second and subsequent discs are played.
1 [Performance is performed.

When the beginning performance of each side of all discs is completed, the 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. In addition, FIG. 38 shows that when the index scan button is pressed on the MWI where the beginning of a certain song on a given disc is played at #8, the beginning of the music on each side of this disc is canceled and the beginning of the music on each of the following discs is canceled. This indicates that the beginning of the first song 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.

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 urging force of the coil spring 228 (thereby, 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 as the support arm 1980 rotates, 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), and the sub-arm 235 rotatably supports the pressing member 192 at its free end. Become. A rack portion 233b is formed on 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, the sub-arm is biased towards the non-clamped position (the position of the sub-arm where the pressing part @ 192 attached to the sub-arm separates from the main surface of the disk 17). A coil spring 237 is interposed therebetween. Zabu 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 trivial! As detailed above, the multi-disc play V according to the present invention includes a housing (2), a turntable (
79) a playing means disposed within the housing;
A plurality of disks (17) are arranged and housed in order in a direction substantially perpendicular to the disk holding portion of the turntable, holding one disk so that the disks can be moved while being mounted on the main surface of each disk, and A magazine (5) is detachably attached to a predetermined attachment portion in the housing, and a magazine attachment/detachment mechanism (IU!i holding plate 3) is attached to and ejected from the attachment portion.
7. a motor 50, etc.), and a disk that sequentially selects arbitrary disks in the magazine and conveys them onto the disk 10 of the turntable, and conveys the disks from above the holding surface of the disk 1υ into the magazine. It includes a transport mechanism, and a section for controlling the playing means, the magazine attachment/detachment mechanism, and the disk transport #M mechanism.

As described above, since the magazine is equipped with the magazine attachment 1152 mechanism that automatically attaches and detaches the magazine to and from the player housing, the operability of attaching and detaching the magazine is good, and the listener does not feel bothered at all.

Further, in the multi-disc player a5 according to the present invention, the control section has eject means for issuing a b magazine eject operation command during disc play in response to a manual eject command. Therefore, it is possible to change the disc in the magazine without interrupting disc play.
You can enjoy many of your favorite songs continuously for a long time.

Furthermore, in the multi-disc player according to the present invention, the disk transport mechanism includes a disk protruding and storing means (comprised of an actuating rod 112, etc.) for protruding and storing the disk in the magazine along the main surface of the disk.
and a disk that is movable along the arrangement direction of each of the disks, and that includes a disk holding part (85) that supports a disk that protrudes from the magazine, and that moves the disk in a direction substantially perpendicular to the disk holding surface of the turntable. and a moving means, wherein the control section checks whether or not there is a storage section in the magazine for storing the disk when the disk is transported from above the disk holding section into the magazine. It has storage section confirmation means.

In other words, if a magazine with no empty space is installed in the disk storage section while a disk remains on the disk holding section, this magazine is ejected and another magazine with a disk storage section is installed. It can be done.

Therefore, the disk is prevented from being inserted into the magazine, and the playing operation is performed smoothly and reliably.
