The carriage 47 is formed so that a portion thereof can be inserted into the storage container 1 as shown in FIG. 5, and supports the disk 2 on its upper surface as shown in FIGS. 6 and 7. It is formed like this. Furthermore, an opening 55 is provided in the center so as not to interfere with the rotational drive of the disc 2 and optical reproduction when the disc is moved to the play position shown in FIG.

A pair of pawls 49 arranged to operate simultaneously on the connecting member 56 are connected to the shaft 47 at the distal end of the carriage 47.
Each is attached so that it can rotate freely around the center. Also,
As shown in FIG. 6, this pawl 49 is formed so as to protrude from the upper surface of the carriage 47 and press against the side surface of the disk 2 when it stands up.
As shown in the figure, it is formed so that it does not protrude from the upper surface of the carriage 47 when it is folded down.

One end of the link 50 is connected to the pawl 49, and the other end is connected to the lower end of the lever 52. Further, the link 50 is biased to the right in FIG. 6 by a coil spring 59 stretched between the link 50 and a protrusion 58 projecting downward from the carriage 47. Therefore, if the plunger solenoid 51 disposed on the carriage 47 is not energized,
As shown in FIG. 7, the link 50 is displaced to the right by the spring 59, and the pawl 49 rotates counterclockwise and falls below the disk 2. On the other hand, when the plunger solenoid 51 is energized, the link 50 moves to the left as shown in FIG. It becomes possible.

As is clear from FIGS. 5 and 8, the carriage moving mechanism includes a carriage moving motor 60 mounted on a movable base 33, a pulley 61 coupled thereto, and a driven pulley mounted on the movable base 33. 62, a belt 63 stretched between the pulleys 61 and 62, and a connecting member 64 that connects the belt 63 and the carriage 47.

A V-shaped groove is provided in the guide member 48 so that there is no difference in height between the upper surface of the guide member 48 and the guide member 7, and the side surface of the carriage 47 is engaged with the V-shaped groove.

As is clear from FIGS. 1, 9, and 10, the disk rotation mechanism 35 includes a disk motor 6.
7, a turntable 68, a clamper 69,
It consists of a mechanism for moving these between the non-play position shown in FIG. 9 and the play position shown in FIG. To enable movement of the motor 67 and clamper 69, the motor 67 is fixed to a support 70 shown in FIG. You will be guided around freely. The support 70 also supports the reproducing optics 36, ie, the optical reading head and the radial transport mechanism for this head.

In order to simultaneously displace the turntable 68 and the clamper 69 by a common driving source, a clamping motor 72, a cam 73 coupled thereto, and a cam 7

A fixed arm 77 that rotatably supports the is provided. One end of the rotating arm 74 is the movable base 33
It is rotatably supported by a shaft 78 at the hanging portion of the support body 70 and is engaged with a pin 80 of the support body 70 through an elongated hole 79. Accordingly, the support body 70 moves upward or downward in FIG. 9 following the rotation of the arm 74. Also, rotating arm 7
4 is biased upward, ie, counterclockwise, by a spring 81. Therefore, the rotating arm 74 is displaced along the cam surface of the elliptical cam 73. Connecting rod 7
5 moves in the vertical direction following the displacement of the rotating arm 74. The lever 76 is connected to the shaft 82 of the fixed arm 77.
The clamper 69 is rotatably supported at one end of the clamper 69.
The other end is connected to the connecting rod 75 by a pin 83. Therefore, when the cam 73 rotates 90 degrees from the position shown in FIG. 9 to the position shown in FIG. The clamper 69 and turntable 68 approach each other to clamp the disk 2.

Incidentally, as shown in number 11, a disk 84 is fixed to the shaft of the cam 73. Therefore, the angle of the cam 73 can be determined by detecting the slit 85 provided in the disc 84 with a position detector 86 using a photocoupler.

Next, the operation of this device will be described.

Disks 2 are stored one by one in a predetermined order on each shelf 3 of each storage container 1, 1a, 1b with the recording surface facing down. In addition, leaf springs 12, 1 are installed at the entrance of the shelf 3.
3, so when inserted, this is pushed out,
After insertion, it is pressed against the side surface of the disk 2. As a result, the disk 2 is stably accommodated in the container 1.

Next, the disk storage container 1 is fixedly placed at a predetermined position on the rotary plate 19 as shown in FIGS. 1 and 4. At this time, the counter 32 shown in FIG. 4 is reset, and the first container 1 is aligned with the disk attachment/detachment direction. Further, a second container 1a and a third container 1b are arranged counterclockwise.

Since playback can be started through the above steps, the microcomputer, ie, microprocessor, specifies the disk to be played from now on. That is, 3
One of the three containers 1, 1a, and 1b is selected, and the role of the disk 2 on the shelf 3 for that capacity is specified. If the first container 1 is selected, there is no need to rotate the rotary plate 19, and the process moves on to the next operation. However, if a container 1a or 1b other than the first is specified, the plunger solenoid 28 shown in FIG. 4 is energized, the roller 25 escapes from the first recess 23a, and the switch 31 is turned on. In response to turning on the switch 31, the container rotating motor 21 shown in FIG. 1 starts rotating, and the rotating plate 19 starts rotating clockwise in FIG. 4. When the rotary plate 19 rotates, the solenoid 28 is turned off, but the roller 25 rolls around the periphery of the rotary plate 19 and keeps the switch 31 on, so that the rotation of the motor 21 is maintained. After that, the roller 25 moves to the second
The motor enters the second recess 23b, the switch 31 is turned off, and the rotation of the motor 21 is temporarily stopped. When switch 31 is turned off, this counter 32
and the counter 32 counts the second container 1a.
Outputs a signal indicating that Then, the microcomputer judges whether it is the specified container or not. If yes, the container selection is completed, and if yes, the plunger solenoid 28 is operated again, and the roller 25 is the third one. recess 2
Rotary plate 19 is rotated until it engages with 3c.

When it is determined by the above operation that the designated container 1 is arranged so as to match the disk attachment/detachment direction as shown in FIG. 1, the height position of the shelf 3 of the desired disk 2 is then indicated. The shelf 3 is searched in response to the designation signal. That is, the movable base 3
By detecting the position of the reduction gear 87 of the reduction mechanism 45 connected to the motor 41 for the vertical movement of No. 3 with a position detector 88 made of a photocoupler,
Obtain a signal indicating the height of the movable base 33, supply this signal to the microcomputer, compare it with the height of the shelf 3 specified here, and if they do not match, move the movable base 33 until they match. move it. When the output of the position detector 88 and the specified height signal match, a stop signal for the motor 41 is generated, and the movable base 33 is fixed. Further, in response to the signal based on the above coincidence, the carriage moving motor 60 shown in FIGS. 5 and 8 is energized, and the carriage 47 is moved from the play position shown in FIG. 8 to the disk pull-out position shown in FIG. . That is, the carriage 47 is inserted under the disc 2 of the container 1.

When the carriage 47 moves to a position where the left end position detection switch 65 shown in FIG. 5 is turned on, the rotation of the motor 60 is stopped in response to the turning on of the switch 65. In addition, in response to turning on the switch 65, the plunger solenoid 51 shown in FIGS. 5 and 6 is turned on, and the claw 49 stands up in the back space 17 of the disk 2, and the plunger solenoid 51 shown in FIG. stand out like that.

In response to the detection of the on state of the plunger solenoid 51 in FIG. 5, that is, after a minute delay time from the on command of the plunger solenoid 51, a reverse drive signal for the carriage movement motor 60 is generated, and the plunger solenoid 51 is maintained on. The carriage 47 moves from the position shown in FIG. 5 to the position shown in FIG. At this time, since the claw 49 is standing up, the claw 49
presses the side of the disc 2 to the right in FIG. 5, and the disc 2 is pulled out together with the carriage 47 to the play position shown in FIG.

When the carriage 47 reaches the position shown in FIG. 8, the right end detection switch 66 is turned on, the rotation of the motor 60 is stopped, and the movement of the carriage 47 is also stopped. Further, in response to turning on the switch 66, the plunger solenoid 51 is turned off, and the pawl 49 falls to the position shown in FIG. 7 by the action of the spring 59.

The presence or absence of the disk 2 is detected by the photocoupler 89 shown in FIG.
The cam motor 72 shown in FIG. 9 rotates in response to the ON signal of
Rotate to the position shown in the figure. Incidentally, when the rotation of the cam 73 by 90 degrees is detected by the disk 84 and the detector 86 in FIG. 11, the motor 72 is stopped. When the cam 73 rotates from the position shown in FIG. 9 to the position shown in FIG. 68 is raised, the turntable 68 supports the disk 2, and the disk 2 is lifted from the carriage 47. On the other hand, the lever 76 is rotated counterclockwise in conjunction with the rotation arm 74 as shown in FIG. 1, and the disk 2 is held between the clubber 69 and the turntable 68.
As a result, the disk 2 can rotate without being restricted by the carriage 47 in any way. Further, the optical device 36 also rises at the same time as the turntable 68, and is in a playable position.

The 11th point is that the cam 73 is in the position shown in Figure 1.
When detected by the detector 86 shown in the figure, the disk motor 67 is energized in response, and the disk 2 starts rotating. Further, the optical device 36 is sent in the radial direction of the disk 1 by a radial direction sending mechanism (not shown), and the optical beam is scanned in a spiral or concentric pattern to read the recorded signal.

In response to an operation to end or stop the play of the disc 2, the cam motor 72 is turned on, and the cam 73 is rotated 90 degrees from the position shown in FIG. 1 to the position shown in FIG. 9. When this is detected by the detector 86 in FIG. 11, the cam motor 72 is controlled to be turned off, and the plunger solenoid 51 for the pawl is turned on. In addition, in response to the rotation of the cam 73 to the position shown in FIG. 9, the rotation arm 74 rotates clockwise, the turntable 68 descends, and the clockwise rotation of the lever 76 causes the clamper 69 to rotate. Away from disk 2,
The disk 2 is now free and placed back on the carriage 47.

When the plunger solenoid 51 is energized, the pawl 49 stands up at the position shown in FIG. 8, and the left side position of the disk 2 is restricted. Further, in response to turning on the solenoid 51 or an output from the cam angle position detector 86, the carriage motor 60 is energized, and the carriage 47 starts moving from the position shown in FIG. 8 to the position shown in FIG. 5. At this time, the disk 2 is pushed to the left by the two pins 53 and 54 on the carriage 47, and is inserted into the container 1 together with the carriage 47.

When the carriage 47 turns on the left end detection switch 65 as shown in FIG. 5, the solenoid 51 is turned off, the pawl 49 falls down as shown in FIG. placed on the shelf 3 and returned to the original position shown in FIG.
rotation stops.
