When it is confirmed that the specified disk is stored in the magazine 5, the control unit causes another disk to be mounted on the disk holding unit 85 (the disk holding unit is referred to as a tray in the flowchart). Is checked by the photo sensor 167 (step S ₆ ), and whether or not the storage section for storing the other disk is in the magazine 5 is checked by the photo sensors 67 to 69 (step S ₇ ). . If there is another disk on the disk carrier 85 (tray) and there is no storage in the magazine 5 that can store this disk,
The magazine is ejected to prompt the exchange of
Made known to the listener by the alarm (step S _8). When a storage portion capable of storing the other disk is provided in the magazine 5 or replaced with a magazine having a storage portion, the other disk is stored in the magazine 5 by the pushing arm 121 (see FIG. 15). It is (step S _9).

If it the other disk is not on the disk carrying section 85 is confirmed, the disk carrying section 85 is moved to the storage position of the specified disk 17 (step S _10).
The stop of the disc holder 85 with respect to the designated disc storage position is performed by the photo sensors 162 and 212. When the disk carrier 85 stops, the operating rod 112 (see FIG. 15 and the like) is protruded rightward (in the direction opposite to the arrow X), whereby the trigger lever 26 (third illustration) in the magazine 5 is operated. The disk 17 to be played is projected out of the magazine 5 and moves onto the disk carrier 85 (step
S _11).

The disc protruding from the magazine 5 is moved by the swing lever 147,
Positioning means, such as 148 (shown in FIG. 15), is positioned at a predetermined position (directly above the turntable 79) on the disk holder 85, and when this is confirmed by the photo sensor 167, the motor 108 (see FIG. 10) Rotates to move the moving body 99 forward (in the direction of the arrow Y), and the disk holder 85 holding the disk is lowered (step
S _12). Disk carrying section 85 is in the process of moving to its lowermost position, the disk 17 that is on the disk carrying section is placed on the disk carrying surface 79a of the turntable 79 (10 shown) (step S _13).

The moving body 99 continues to move forward even after the disk holder 85 reaches its lowermost position, whereby the lever member A176 shown in FIG. 10 rotates for the first time in the counterclockwise direction in FIG. I'm sullen. Therefore, this lever member A1
The slide plate 179 connected to 76 moves to the left (in the direction of arrow X), and the clamp mechanism is operated.

 The operation of the clamp mechanism will be described in some detail.

When the slide plate 179 moves to the left (in the direction of the arrow X), first, the support arm 198 of the clamp mechanism rotates about the rotation support shaft 187, for example, in the counterclockwise direction in FIG. When the support arm 198 rotates by a predetermined angle and the pressing member 192 reaches just above the turntable 79, (the arm main body 189 which is a constituent member of the support arm).
Is engaged with the pin 202, and the rotation of the support arm is stopped. After this, slide plate
179 is further driven to the left, thereby supporting arm 1
The rotation lever 196, which is a component member of 98, rotates about the pin 196a, so that the slide plate 194 connected to the rotation lever moves along the arm body 189. Thus, as it is apparent from FIG. 13, the sub-arm 190 is swung downward, the pressing member 192 is the disc is clamped in contact with the main surface of the disk 17 (step S _14).

On the other hand, the movement of the slide plate 179 to the left (the direction of the arrow X) causes the lever member B183 shown in FIGS. 10 and 15 to rotate around the pin 183a in the counterclockwise direction in both figures. Then, as is apparent from FIG. 15, the pin 183e of the lever member B183 engages with the interlocking lever 149 to move the interlocking lever forward (in the direction of the arrow Y). Therefore, the swinging levers 147 and 148 that have positioned the disk 17 on the disk carrying portion 85 are separated from the outer peripheral portion of the disk 17. In addition, the rotation of the lever member B183 in the counterclockwise direction causes the protrusion 183c of the lever member to move the moving plate 170 (first
0) is pushed to the left (in the direction of arrow X). Therefore, the other swing lever 155 shown in FIG. 15 is separated from the outer peripheral portion of the disk. The movement of the moving plate 170 to the left causes the lifting lever 171 shown in FIGS. 11 and 15 to move.
Rotates about the pin 171a in the counterclockwise direction in FIG. 11, whereby the disk guide member 86 is swung upward by a predetermined angle. Thus, the disc can be played, and the turntable 79 and the carriage 80 (shown in FIG. 10 and the like) operate to start playing (step
S _15).

When playing is finished disc is being returned into the magazine 5 (step S ₁₆₎ is, are not described in detail since the disk return operation to the magazine 5 is made by tracing the substantially reverse process of the disk loading operation described above . 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. In addition, the control unit checks with the photosensors 67 to 69 whether or not a storage unit for storing a disk to be returned to the magazine 5 is present in the magazine 5. Fifteenth
As shown in the drawing, when the pushing arm 121 is at the pushing position for pushing the disc 17, the tip of the pushing arm seems to contact the magazine 5, but the magazine 5 is formed with a cutout 5b in this portion. Therefore, the operation of the pushing arm is not hindered. FIG. 2 (a),
This notch 5b is also shown in (d) and (f),
The listener can grasp the disk 17 with the nail and take it out of the magazine 5 through the notch. However, the cutout portion is quite small, and the listener can grip only the outer peripheral portion of the disk 17, so that the recording surface of the disk is not damaged by the listener's nail.

Hereinafter, the above operation is repeated according to the designated disk. When the magazine 5 is ejected in order to exchange the magazine 5, the lid 6 of the magazine insertion opening 3a is opened while being pushed by the magazine to be ejected.

Next, an 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 the automatic performance means is operated manually. First, the disc to be played is specified (step
When S ₂₀₎ is being, the designated disk is conveyed onto the turntable 79 (Step S _21). Then, playback from the head of the disk is started (step S _22), it is exchanged when the player has finished the next disk. When the disk are sequentially switched (step S ₂₆₎ has been played last specified disk is completed, it starts playing from the first disk again. When the stop button is pressed during the continuous performance, the performance ends.

FIG. 35 shows the operation of the automatic performance means when a program is programmed.

FIG. 36 illustrates a tune head detecting means for sequentially detecting the tune head of each tune recorded on each disk in the magazine 5 and continuously for a plurality of disks. First, when an index scan button (any of the operation button groups 7 to 10), which is a so-called lock button, is pressed,
The button locks when pressed. Then, the number X of the disc to leave the index scan is 1 and the set, the first track of the song head of the first disc is played (step S ₄₁ ~S _44). If left index scanning button in this state is depressed, the first sheet of the second music following song head of each song disks are sequentially played (S ₄₅ ~). When the beginning of each song recorded on the first disc ends,
The beginning of each song is performed for the second and subsequent discs. When the beginning of each song of all the discs is completed, the normal performance starts from the first disc. Also, when the RELEASE button is pressed during the beginning of each song, the operation shifts to the normal performance.

FIG. 37 and FIG. 38 are diagrams for explaining the deformation of the tune detecting means. FIG. 37 shows that if the index scan button is pressed immediately after the head of a song on a predetermined disc has been played, the beginning of the next song begins. FIG. 38 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 each song on this disc is released, and the first disc of the next disc is released. This indicates that the beginning of the tune is performed sequentially.
