By strengthening the tray drive mechanism,
It is possible to correct the position of the tray part 100 by overcoming the frictional force of 150. Then, when the cam gear 207 rotates further,
The second cam portion 209 presses the lever 218 to rotate the lever 218 counterclockwise. Here, the disk selection mechanism section 200 is arranged in a positional relationship such that the tip of the lever 218 can engage with the base end of each lever 104 of the push-up lever mechanism 106 incorporated in the tray section 100 described above. There is. This causes the lever 218 to move as shown in FIGS.
Then, as shown in FIG. 11, the accessed lever 104 at the predetermined position is rotated clockwise in the figure, so that only the target disk stored in the push-up groove 115 of the lever 104 is removed from the position indicated by the chain line in the figure. By being able to push up about 5 mm to the position indicated by the solid line, it becomes possible to select only the target disk accessed here. In addition, the actual selection completion state is cam gear 207.

This also functions as a disk selection operation and a tray section 100 lock operation. Moreover, if the motor 201 is driven clockwise after this operation, it goes without saying that the original state will be restored through the reverse procedure as described above. Next, the disk 101 selected from the tray section 100 as described above is

0 to the disk pocket mechanism section 500 for reproduction. After the reproduction is finished, the disk 101 is returned to the tray section 100 via the disk temporary standby mechanism section 600 and the unloading mechanism section 700 . Here, before explaining the details of the first and second loading mechanism sections 300 and 400 , the overall movement process of the disk 101 during loading and unloading will be briefly explained. That is, FIGS. 12a and 12b show the movement of the disk 101 from the top and front sides of the disk autochanger device shown in FIG. 1, respectively. In addition, in Figure 12 a and b, DC ₁ to
DC ₁₂ indicates the center position of the disk 101, and disks 101 shown with the same symbol between FIGS. 12a and 12b indicate that the center position is the same. First, in FIGS. 12a and 12b, when the disk 101 is stored in the tray section 100 as described above, the center position of the disk 101 is
The position shown is DC ₁ point. The disk 101 is connected to the disk selection mechanism section 200.
When pushed up from the tray section 100 by
Its center position is moved to the DC ₂ point directly above the DC ₁ point. Then, due to the action of the control circuit 910, the first loading mechanism section 300 starts to be driven. This first loading mechanism section 300
12 shows the disk 101 pushed up from the tray section 100 , rolled to the right in FIG.
It is taken out from 00. And this first
By the loading mechanism section 300 , the rolled disk 101 first climbs over the front edge 113 of the tray section 100 , its center position is moved to _three points DC, and the disk 101 is moved between the tray section 100 and the disk pocket mechanism section. 500 (see FIG. 12a). This loading path 301 is connected to the disk 101.
It is formed into a narrow shape that is slightly wider than the thickness of the
Disk 101 taken out from tray section 100
The entrance portion 302 into which the disc 101 enters has a wide tapered opening as shown in FIG. 12a, so that the disc 101 can easily enter therein. Then, the disk 101 transferred into the loading path 301 by the first loading mechanism section 300 is stopped within the loading path 301, and its center position is set at the DC ₄ point. When the disk 101 is stopped in the loading path 301 in this way, the second loading mechanism 400 starts to be driven by receiving the power from the first loading mechanism 300 . This second loading mechanism section 400 lifts up the disk 101 stopped within the loading path 301 and moves its center position to _five points DC. Here, the loading path 301 has _a slope ( 12th (lower right in Figure b) is formed. Therefore, the disk 101 rolls along the above-mentioned slope and is housed in the loading position (IN) within the disk pocket mechanism section 500 , with its center position being at the DC ₆ point. Then, under the action of the control circuit 910, the disk pocket control mechanism 550 is started to be driven, and the disk 101 is moved past the unloading position (OUT) to the playback position (PLAY). At this playback position (PLAY), disk 101
Its center position is moved to DC ₇ point, which is slightly above the DC ₆ point in FIG . In this state, the disk 101 is rotated and played by the disk playing mechanism section 580 . When the playback operation is completed in this state, the disk pocket control mechanism 550 is driven again by the action of the control circuit 910, and the disk 101 is moved to the unloading position (OUT) so that its center position is at the DC ₈ point. It will be done. This unloading position (OUT) is set between the loading position (IN) and the playback position (PLAY), and at the unloading position (OUT), the disk 101 is arranged in parallel with the loading path 301. It is sent out to an unloading path 701. Like the loading path 301, this unloading path 701 is formed in a narrow shape that is slightly wider than the thickness of the disk 101, and is located at the unloading position (OUT) in the disk pocket mechanism section 500 .
An inclination (downward left in FIG. 12b) is formed that causes the disk 101 located in the tray part 101 to roll out in the direction of the tray part 100 due to its own weight. Therefore, when the disk 101 reaches the unloading position (OUT), it naturally moves along the above-mentioned slope to the disk pocket mechanism section 500.
It rolls out from inside and enters into the unloading path 701. Here, of the unloading path 701, an entrance portion 702 into which the disk 101 that has rolled out from the disk pocket mechanism section 500 enters is wide and tapered as shown in FIG. 12a.
The disk 101 is designed to be easily inserted. The disk 101 that has fallen into the unloading path 701 is temporarily held in the unloading path 701 by the disk temporary standby mechanism section 600 , and its center position is
Scored DC ₉ points. Unloading path 70 of this disk 101
1 continues for a predetermined period of time defined by the control circuit 910. When the predetermined time period has elapsed, the control circuit 910 operates to start driving the unloading mechanism section 700 . This unloading mechanism section 700 operates on a disk 101 that is in a standby state within an unloading path 701.
12 to the left in FIG .
It moves to 0. Therefore, disk 1
01 is stored in the tray part 100 beyond the front edge 113 of the tray part 100 , and its center position is
Scored as DC ₁₀ points. Here, the disk 101 takes different routes during loading and unloading. Specifically, the disk 101 in the loading path 301 and the unloading path 701
There is a tray section 10 between the disk 101 located at
In terms of the number of disks 101 stored in the depth direction of 0, there is an interval in which 1012 disks can fit. In other words, the position of the disk 101 indicated by the dotted line in FIG.
This corresponds to the 1013th image. Therefore, in this disk automatic changer device, when a desired disk 101 is selected by the disk selection mechanism section 200 , the disk 101 to be selected by the tray drive mechanism section 150 is first selected from the entrance section 301 of the loading path 301.
The tray section 100 is moved so as to face the.
The movement of the tray section 100 at this time is as follows :
This is done by driving the tray drive mechanism section 150 in accordance with the control of the control circuit 910 based on the addresses (that is, disk access information) written corresponding to each groove of 00. Then, disk 1 selected in this way
01 from the unloading path 701 to the tray section 100, the control circuit 9
10, the tray section 100 is moved to a position shifted by the 1013th disk from the position of the tray section 100 corresponding to the disk access information based on the disk access information used to move the tray section 100 earlier. I am trying to move it automatically. Therefore, the empty groove of the tray section 100 after the disk 101 is taken out can be made to face the outlet section 703 of the unloading path 701. Here, the operation of causing the empty groove of the tray section 100 after the disk 101 is taken out to face the outlet section 703 of the unloading path 701 is to
This is performed when the unloading path 701 is on standby due to the unloading path 701.
Therefore, the tray section 100 is moved from the unloading path 701 by the unloading mechanism section 700 .
The disk 101 sent out is returned to the groove of the tray section 100 from which it was first taken out, and a desired disk 101 is selected from the tray section 100 , reproduced, and returned to the original groove of the tray section 100 . This is the end of the returning operation. One disk 101 is placed in the tray section 100.
The operation of taking out a plurality of disks 101 from the tray section 100 for playback and returning them to the tray section 100 has been described.Next, the operation of sequentially taking out a plurality of disks 101 from the tray section 100 for playback and returning them to the tray section 100 will be described. First, a desired first disk 10 out of the plurality of disks 101 housed in the tray section 100 is selected.
1 is selected and pushed up from the tray section 100 , the first disk 101 is moved to the first and second loading mechanism sections 300 , 40, as described above.
0, the data is transferred to the carry-in position IN in the disk pocket mechanism section 500 , and is played back at the playback position PLAY. Here, for example, during playback of the first disk 101, the tray section 100 is operated to access the second disk 101 to be played next, that is, the second disk 101 is moved to the entrance section 302 of the loading path 301. An operation is performed to move the tray section 100 to the opposing position. However, even after this access operation is completed, the second disk 101 is still not pushed up from the tray section 100 . After the regeneration, the first disk 101 is moved from the unloading position OUT to the unloading path 7.
01, and the disk temporary standby mechanism section 6
00 puts it into a standby state. When the first disk 101 is in the standby state, the second disk 101 is pushed up from the tray section 100 where the access operation has been completed, and the first and second disks are
By the action of the loading mechanism sections 300 and 400 , the disc is transferred to the loading position IN in the disk pocket mechanism section 500 , and is played back at the playback position PLAY. During playback of the second disk 101, the tray portion 100 is moved so that the groove in which the first disk 101 was housed is connected to the outlet portion 70 of the unloading path 701.
Moved to face 3. Thereafter, the first disk 101 in the standby state is returned to the tray section 100 by the unloading mechanism section 700 . And this second disk 10
1, the third disk 1 to be played next
01 is accessed by the tray section 100 , and the same operation is repeated thereafter, whereby a plurality of disks 101 are automatically taken out from the tray section 100 one after another and played back .
An operation is performed to return it to 0. It should be noted that while it has been described above that during playback of the first disk 101, the access operation of the tray section 100 is performed to the second disk 101 to be played next, but this access operation of the tray section 100 is , may be performed while the first disk 101 is temporarily on standby within the unloading path 701. In this way, the plurality of disks 101 are sequentially taken out from the tray section 100 and placed in the playback tray section 10.
A series of operations for returning the value to 0 are performed by the control circuit 91 based on the operation command signal from the operation section 900.
0 is performed by sequentially controlling each mechanical section so as to have a predetermined time sequence. Therefore, as described above, the sequence control function of the control circuit 910 determines whether the access operation of the tray section 100 is performed during playback of the first disk 101 or when the first disk 101 is in the standby state. The selection can be made by appropriately setting . As described above, in this disk automatic changer device, the disk 101 takes different paths (loading path 301 and unloading path 701) during loading and unloading.
the first disk 101, which has finished playing, is made to temporarily stand by during unloading;
During this waiting period, the next second disk 101 is taken out from the tray section 100 and played back.
While the first disk 101 is being played, the first disk 10
1 is returned to the tray section 100 , so
So-called loading is prioritized, and from the end of playback of the first disk 101, the second disk 101 is loaded.
You can shorten the time it takes to start playing the

01 and returning it to the tray section 100. However, as mentioned earlier, this disk automatic changer device is capable of transporting the disk 101 to be recycled from outside, or transferring the disk 101 after the reproduction is completed. A disk external loading/unloading mechanism section 800 is provided which can transport the disk to the outside. That is, this disk external loading/unloading mechanism section 800 , which will be described in detail later, loads the disk 101 (center position DC ₁₁ points) into the disk pocket from the outside of the disk autochanger device, as shown in FIGS. 12a and 12b again. Mechanism part 500
The disk 101 at the carry-in position IN in the disk pocket mechanism section 500 can be regenerated, and the disk 101 at the carry-out position OUT in the disk pocket mechanism section 500 can be recycled.
can be sent out to the outside (center position DC ₁₂ points). Therefore, in this disk automatic changer device, the disk 1 housed in the tray section 100
In addition to regenerating and returning 01, it also regenerates the disk 101 brought in from the outside and transports it outside, transports the regenerated disk 101 taken out from the tray section 100 , and The action of the control circuit 910 also makes it possible to store the reproduced disc 101 in the tray section 100. In this case, while the disk 101 is being played, the disk 101 is not carried into the disk pocket mechanism section 500 from the outside.
Unless the disk 101 is delivered to the unloading path 701 or carried out to the outside, the disk 101 is not carried into the disk pocket mechanism section 500 from the outside. The overall movement process of the disk 101 has been described above, and next, the first loading mechanism section 300 , which is the gist of the present invention, will be described. That is, as shown in Figure 1 again,
On the upper plate 14 and the left end side plate 12, there is a substantially arch-shaped 2 plate above the disk 101 housed in the tray portion 100 along the periphery of the disk 101.
The book guide rails 303 and 304 are
00 are arranged in parallel in the depth direction. The upper surfaces of the guide rails 303 and 304 in FIG.
05,306 is formed. A loading unit 307 is attached to the guide rails 303 and 304, as shown in FIG. 13 (the guide rail 304 is not visible in FIG. 13). This loading unit 307 is configured to rotate the guide rail 30 by rotating a built-in motor 308 in the forward and reverse directions.
3,304 in one direction and the other direction, respectively. FIG. 14 shows the structure of this loading unit 307. In the figure, 309 is a support formed by bending a metal plate into a substantially U-shape. Through holes 312 and 313 are formed in opposing side surfaces 310 and 311 of this support body 309, respectively, and approximately cylindrical bearing members 314 and 315 are fitted into these through holes 312 and 313, respectively. There is. A rotating shaft 316 is rotatably inserted through the bearing members 314 and 315.
Both ends of this rotating shaft 316 are connected to the support body 309.
It protrudes outward from both end surfaces 310, 311, and washers 317, 3 are attached to both protruding parts, respectively.
Moving gears 319 and 320 are fitted through 18. And these moving gears 319, 32
0 rotates integrally with the rotating shaft 316, and the teeth 30 of the guide rails 303, 304
5 and 306, respectively. Here, one side surface 310 of the support body 309
As shown in FIG. 13 again, cylindrical guide portions 321 to 323 that contact the guide rail 303 in opposite directions are attached to the outer surface of the guide rail 303 . Further, although not visible in FIG. 13, on the outer surface of the other side surface 311 of the support body 309, there is a cylindrical guide portion that contacts the guide rail 304 on the opposite side and corresponds to the guide portions 321 to 323. It is attached. By the action of the guide parts 321 to 323 on one side 310 of the support body 309 and the guide parts on the other side 311, and the moving gears 319, 320, the loading unit 307 is moved to the guide rails 303, 304. It is supported by Further, the rotating shaft 316 has a substantially central portion loosely inserted into a substantially cylindrical drive gear 324 . This drive gear 324 is rotatable separately and independently from the rotation shaft 316. Furthermore, first and second gear portions 325 and 326 are formed on the circumferential side of this drive gear 324, respectively. A worm gear 327 fitted onto the rotating shaft (not shown) of the motor 308 is meshed with the first gear portion 325. Here, the left end surface of the driving gear 324 in FIG. 14 is connected to a substantially cylindrical friction plate 329 via a ring-shaped friction member 328 made of, for example, felt. This friction plate 329 is fixed to the rotating shaft 316 by pressing the tip of a screw 330 which is screwed from the outer periphery toward the center of the friction plate 329 to the rotating shaft 316. It rotates integrally with 316. Further, a recess 331 is formed at the approximate center of the right end surface of the driving gear 324 in FIG.
32 is loosely fitted. This spring 332
has one end in contact with the bottom surface of the recess 331 and the other end in contact with a ring-shaped spring receiving plate 334 positioned by a washer 333 fixed to the rotating shaft 316. The drive gear 324 and the friction plate 329 are urged to be pressed against each other via the friction member 328. Therefore, when the motor 308 is driven in forward and reverse rotation, the rotational force is transferred to the worm gear 3.
27, the driving gear 324, the friction member 328, the friction plate 329, and the rotating shaft 316 are transmitted to the moving gears 319, 320, and the moving gear 31
9 and 320 are rotated in the forward and reverse directions, thereby allowing the loading unit 307 to be moved in one direction and the other direction on the guide rails 303 and 304. Here, on the side surface 311 of the support body 309,
One end of the shaft 335 is fixed. This axis 33
5, the second gear portion 32 of the drive gear 324;
A transmission gear 336 meshed with 6 is freely rotatably fitted. The transmission gear 336 is prevented from coming off by a ring-shaped receiving member 337 fitted to the other end of the shaft 335. The support body 309 also has both end surfaces 31
Approximately in the center between 0 and 311, the side surfaces 310 and 31
A support portion 338 arranged in parallel with 1 is bent. One end portion of a shaft 339 is fixed to this support portion 338 . A substantially cylindrical operating gear 342, which is formed integrally with first and second gear parts 340 and 341 having different diameters, is rotatably fitted onto the shaft 339. Here, the first gear portion 340 of this operating gear 342 is meshed with the transmission gear 336. Furthermore, one end of a loading lever 343 is loosely fitted into the tip of the shaft 33 so as to be freely rotatable. This loading lever 343
It is prevented from coming off by a washer 344 fixed to the tip of 39. Between this loading lever 343 and the operating gear 342, there is a
A ring-shaped friction member 34 made of felt, etc.
5 is interposed. In addition, the operating gear 342
A ring-shaped spring receiving plate 346 is provided on the left end surface in FIG.
A coiled spring 347 is interposed between the drive gear 342 and the support portion 338, so that the operating gear 342 and the loading lever 343 are urged to be pressed against each other via a friction member 345. It is. A rotary shaft 348 is rotatably fitted into the other end of the loading lever 343. A washer 3 is attached to one end of this rotating shaft 348.
A loading gear 350 is fitted into the second gear part 341 of the operating gear 342 via a gear 49. Further, a loading pulley 352 is fitted onto the other end of the rotating shaft 348 via a washer 351. A flange 353 is formed on the circumferential side of the loading pulley 352 and can hold the circumferential edge of the disk 101 in its thickness direction. A ring-shaped friction material 354 made of rubber or the like is provided between the flange portions 353.
is fitted. Here, the loading gear 350 and the loading pulley 352 are rotated integrally via the rotating shaft 348. The operation of the first loading mechanism section 300 configured as described above will be described below with reference to FIG. 15. However, FIG. 15 shows the first loading mechanism section 300 as seen from the front side of the disk automatic changer device shown in FIG.
4. Moving gears 319, 320 and side surface 310,
Since numbers 311, etc. overlap, each number will be shown using one leader line in the figure and two numbers each. First, when the first loading mechanism section 300 is in a non-driving state, the loading unit 307 is located at the left end of the guide rails 303, 304 in FIG. When the loading unit 307 is in the non-driving position, the guide rails 303 and 304 engage with the lower end of the loading lever 343 in FIG. 3
Hold it so that it does not fall downward in FIG. 15 with 39 as the center. L-shaped locking part 355 on the side
is formed. Therefore, when the loading unit 307 is in the non-driving position, not only the disk 101 housed in the tray section 100 and centered at _one point DC, but also the disk selection mechanism section 200 selects the tray section. 10
The loading pulley 352 is also configured not to come into contact with the disk 101 which has been pushed up from 0 to _{the two} center positions DC. Further, when the loading unit 307 is in the non-driving position, the leaf switch 356 attached to the upper plate 14 is pressed by the guide portion 322 and turned on. This leaf switch 356 is for detecting the position of the loading unit 307. When this leaf switch 356 is on (that is, the loading unit 307 is in the driving position), the control circuit 910 detects the position of the loading unit 307. It is in a state where it can output a signal for driving 307. In this manner, when the disk 101 is pushed up from the tray section 100 with the loading unit 307 in the non-driving position, the motor 308 of the loading unit 307 is driven to rotate under the sequence control of the control circuit 910. The rotation direction of this motor 308 is controlled so as to rotate the moving gears 319, 320 clockwise in FIG. 15. Therefore, the loading unit 307 is moved along the guide rails 303, 304 in the direction of arrow _L1 in FIG. Then, the loading lever 343 engages the locking portion 3 formed on the guide rails 303 and 304.
55. Here, the motor 308
The rotational force of and is transmitted to the loading pulley 352. Since the rotation direction of the motor 308 is to rotate the moving gears 319 and 320 clockwise in FIG. 15, the transmission gear 336 is rotated counterclockwise in FIG. It will be rotated clockwise in the figure. Therefore, the loading lever 343 is connected to the loading pulley 352 via the friction member 345.
A rotation biasing force is applied in the direction of bringing the disc 101 into contact with the disc 101. Moreover, the rotational force in the counterclockwise direction in FIG. 15 is transmitted to the loading pulley 352 itself. Therefore, when the loading unit 307 is moved in the direction of arrow _L1 in FIG. 15 and the loading lever 343 is separated from the locking portion 355,
The loading pulley 352, which rotates counterclockwise in FIG. 15, is pushed up from the tray portion 100 and comes into pressure contact with the disk 101, which is located at _{the two} center points DC. In this case, the peripheral edge of the disk 101 is interposed between the flange 353 of the loading pulley 352, and the friction material 354
The circumferential side surface of the material is pressed against the surface of the material. Therefore, as shown in FIG. 12b again, the disk 101 pushed up from the tray section 100 is rolled in a direction to escape from the tray section 100 by the rotational force of the loading pulley 352. itself is moved along the guide rails 303 and 304, and the disk 1
01 is pushed out, the disk 101 ends up rolling along the loading path 30.
1. Here, as shown in FIG. 15, the right end portions of the guide rails 303 and 304 abut against the guide portion 323 of the loading unit 307 (the guide portion of the side surface 311 is not shown), and are loaded. A stopper portion 357 is formed to forcibly stop the movement of the turning unit 307 in the direction of arrow _L1 .
For this reason, the arrow of loading unit 307
Movement in the _L1 direction is stopped when the guide portion 323 abuts against the stopper portion 357. At this stop position of the loading unit 307, the disk 101 has been moved to the position indicated by the center position _DC4 in FIG. 12b. Note that even if the loading unit 307 is stopped, the rotation of the motor 308 is not stopped. That is, when the loading unit 307 is in a stopped state, as shown in FIG.
29, which causes slippage between the two. The rotational force of this drive gear 324 is used for a second loading mechanism section 400 , which will be described later. Therefore, according to the first loading mechanism section 300 configured as described above, the rotating pulley 3
52 is brought into pressure contact with the outer periphery of the disk 101. Therefore, by simply pushing up the disk 101 to be selected from the tray section 100 by about 5 mm,
It is possible to reliably take out the disk 101 while distinguishing it from other disks 101, prevent the wrong disk 101 from being taken out, and is also suitable for miniaturization. Furthermore, since the disk 101 is taken out from the tray section 100 while rolling, the disk 101 can also be taken out smoothly and easily. Furthermore, the flange 353 of the loading pulley 352
Since the outer periphery of the disk 101 is sandwiched between them, the disk 101 can be stably transferred, and the disk 101 can be positioned when it is guided into the loading path 301. This can further contribute to smooth operation. Further, the rotational force of the drive gear 324 is applied to the friction member 3
28 and a spring 332 to the friction plate 329, and in turn to the moving circular gears 319, 320. , 304 is not stronger than the friction force of the friction mechanism. This is irreversible,
This means that the force with which the loading pulley 352 pushes out the disk 101 while rotating is regulated to a certain constant value, so that the disk 101 can be safely transferred without applying excessive force to the disk 101. It is something that can be done. In addition, the operating gear 342 and the loading lever 3
43 means a friction member 345 and a spring 347.
Because they are connected via a friction mechanism consisting of
The force with which the loading pulley 352 is brought into pressure contact with the disk 101 is also regulated to a certain constant value, and in this respect as well, unreasonable force is not applied to the disk 101. Furthermore, as is clear from FIG. 14, the drive gear 3
The transmission gear 3 is smaller than the diameter of the second gear portion 326 of 42.
The diameter of No. 36 is made smaller. For this reason,
The rotational speed of the transmission gear 336 is faster than the rotational speed of the drive gear 324, that is, the rotational speed is increased. The diameter of the transmission gear 336 and the diameter of the first gear portion 340 of the operating gear 342 are approximately equal, and the diameter of the second gear portion 341 of the operating gear 342 and the diameter of the loading gear 350 are approximately equal. It is said that Therefore, the rotational speed of the disc pulley 352 is faster than the rotational speed of the drive gear 324, that is, the rotational speed of the moving gears 319 and 320, that is, the rotational speed is increased. On the other hand, since the diameter of the loading pulley 352 is larger than the diameter of the moving gears 319 and 320, the speed of the peripheral edge of the loading pulley 352, that is, the circumferential speed, is faster than the circumferential speed of the moving gears 139 and 320. It is done like this. For this reason, after the disk 101 is rolled by the rotational force of the loading pulley 352 itself, the loading unit 30 follows the disk 101.
7 will now be moved. Therefore, the loading unit 307 does not move faster than the disk 101, that is, it does not move over the disk 101, and the rotating loading pulley 352 is moved from behind the disk 101 to the disk 101.
1 can be brought into contact with the disk 101 so as to push it out, and the disk 101 can be transferred stably. Next, although not directly related to the gist of the present invention, in order to describe the entire configuration of the disk automatic changer device described here, we will explain the above-mentioned tray 103, its surroundings, and the second loading mechanism section 4.
00, the detailed configuration of the disk pocket mechanism section 500 , disk pocket control mechanism section 550 , disk playback mechanism section 580, disk temporary standby mechanism section 600 , unloading mechanism section 700 , and disk external loading/unloading mechanism section 800 will be explained. First, FIGS. 16a, b, and c are a sectional front view, a front view, and a left side view showing details of the tray main body 103, in which the disks 10 to be stored are shown in FIGS.
Approximately 1/4 as described above, with a radius of curvature R ₁ that conforms to R ₁ as a valley and a radius of curvature R ₂ smaller than R 1 as a peak.
A large number of circumferential storage grooves 102 (50 in the case shown)
are formed continuously in the depth direction at a predetermined pitch (in the case shown, it is 3 mm for a 1.2 mm thick CD, but the valley width is 1.3 and the peak width is 2.2 mm, widening at the end). In addition, the groove 10 described above is also formed in the front edge portion 113 which is connected to the extension line of R ₁ and R ₂ and is slightly higher than the lowest portion A of the groove 102.
A guide groove 1 having a similar shape and parallel to that corresponding to 2.
14 is formed. In addition, the storage groove 1 formed in the tray body 103
02 and the guide groove 114, a bag-shaped notch is formed, and the tip end portions of the levers 104-1, 104-2, . . . of the push-up lever mechanism 106 described above are inserted into the notch 124. In this case, each lever 104 as shown in FIG.
-1, 104-2... are also formed with push-up grooves 115 having valleys and peaks with predetermined radii of curvature R ₁ and R ₂ corresponding to the heat absorption grooves 102 described above. When the push-up lever mechanism 106 is rotatably supported relative to the tray body 103 as described above, the respective grooves 102 and 115 of the two are connected with each other with predetermined radii of curvature R ₁ and R ₂ . It also appears that the former guide groove 114 is continuous with the latter push-up groove 115 (see FIG. 8). Note that the tip of the guide groove 114 is such that when the disk 101 is returned, which will be described later, the disk 101 is placed in the guide groove 114.
It has a predetermined opening angle and is flared toward the end to facilitate entry. In addition, a guide portion 116 that enters the storage groove 102 of the tray body 103 is formed at the tip end of each lever 104-1, 104-2, thereby facilitating the disk push-up operation when selecting the disk 101 described above. It shall be ensured that this can be done smoothly. FIG. 17 shows the light reflection sensor section 174 in the above
, a plurality of sensors S ₁ to _{S 8} are electrically connected vertically at a predetermined pitch on a printed wiring board 176 attached to the inside of a mounting plate 175. S ₁ to S ₈ are each held in a positionally regulated state by a holder 177 having a plurality of holding holes H ₁ to _{H 8} that hold the heads thereof correspondingly. In this case, the holder 177 has slits SL 1 _to SL ₈ formed in front of the holding holes H ₁ to _{H 8} as shown in FIG. 18, but the upper two slits SL ₁ and SL ₂
The width of the slit is 0.5mm, and the width of other slits SL ₃ ~
It is narrowed to half the width of SL ₈ (1mm). Note that these slits SL ₁ to _{SL 8} are connected to each sensor S ₁
〜S ₈ , each sensor S ₁ exists in a substantially semicircular shape, as shown in FIG. 19.
It is formed in such a manner that it faces both the light emitting part (LED) and the light receiving parts P and T of ~ _S8 . The outputs of the two upper sensors S ₁ and S ₂ are for positioning, and are connected in a differential configuration as shown in FIG. 20. That is, by adding the respective outputs of these two sensors S ₁ and S ₂ to the positive and negative phase input terminals (+) and (-) of the operational amplifier (OP), the above-mentioned error signal output from the operational amplifier (OP) is applied. The configuration is such that the motor 172 of the tray drive section 162 is controlled. Further, sensors S ₃ to _{S 8} other than those mentioned above are for reading addresses. Figure 21 shows the reflector plate 1 for access in the above
08, the upper two reflection patterns P ₁ and P ₂ are for positioning, and both overlap by 0.25 mm in correspondence to each storage groove 102 of the tray body 103 described above. In this case, 50 pieces are formed for both. Also, in Fig. 21, other reflection patterns P ₃
~ _P8 is each storage groove 1 of the tray body 103 mentioned above.
Addresses 1 to 50 corresponding to 02 are formed in binary notation. That is, the above-mentioned light reflection sensor section 174 applies reflection patterns P 3 to P that give addresses of 1 to 50 with sensors S ₃ to _{S 8} to the above-described reflection plate 108 attached to the back surface of the tray body ₁₀₃ . After reading ₈ and moving the tray unit 100 via the tray drive mechanism unit 150 to a predetermined access position, the sensors S ₁ and S ₂ position it accurately with an accuracy of 0.25 (±0.125) mm. It is made in such a way that it can be taken out. Next, the second loading mechanism section 400
As shown in FIG. 15 again, when the loading unit 307 reaches the right end of the guide rails 303, 304 in the figure and stops by colliding with the stopper portion 357, the second The gear portion 326 comes to mesh with the cam gear 401. As shown in FIG. 22, the cam gear 401 is rotatably supported by a shaft 403 implanted in a mounting plate 402 installed upright between the main chassis 11 and the upper plate 14. axis 403
It is prevented from coming off by a washer 404 attached to the tip. As shown in FIG. 22, this cam gear 401 is provided with a toothed portion 405 with teeth and a flattened portion 406 without teeth on its circumferential surface. Here, as shown in FIG.
07 is formed. And the cam gear 4
When the second gear part 326 of the drive gear 324 is not engaged with the second gear part 326 of the drive gear 324, an engaging part 409 protruding from one end of the holding member 408 is located at the innermost part of the notch part 407. . This holding member 408 is formed by bending a metal plate into a substantially U-shape, and a shaft 412 implanted in the mounting plate 402 is loosely fitted into both opposing sides 410, 411 of the holding member 408. This allows it to be rotatably supported. One end of one side surface 410 of this support member 408 extends, and the engaging portion 409 is provided protrudingly at the tip thereof.
Further, the holding member 408 has a central portion wound around the shaft 412, and one end portion of the holding member 408 that is wound around the both side surfaces 410 and 412.
The engaging portion 409 is pressed into contact with the cutout portion 407 by a torsion spring 415 that is engaged with a base portion 413 that connects the mounting plate 11 and whose other end is engaged with a pin 414 that projects from the mounting plate 402. 21, that is, clockwise in FIG. When the loading unit 307 reaches the right end of the guide rails 303, 304 in FIG. Since the cam gear 401 is rotating in the same direction as the gears 319 and 320, the cam gear 401 is rotated counterclockwise in FIG. Then, the engaging portion 409 is pressed by the inclined surface of the notch 407 of the cam gear 401, so the holding member 408 rotates counterclockwise in FIG. 15 against the biasing force of the torsion spring 415. be done. At this time, the engaging portion 409 fits into the recess 416 formed on one side surface 310 of the support portion 309, and the engaging portion 409 is held in the recess 416 by the action of the flat portion 406. be done. As a result, the loading unit 307 is fixed at the position where it reaches the right end of the guide rails 303, 304 in FIG. Here, a substantially spiral grooved cam 417 is formed on one surface of the cam gear 401, as shown in FIGS. 15 and 22. This groove cam 4
An engaging portion 419 protruding from one end of a drive lever 418 is loosely fitted into the drive lever 17 . Here, this drive lever 418 is formed by bending a metal plate into a substantially U-shape, and its opposing sides 42
The shaft 4 implanted in the mounting plate 402 at 0,421
22 is loosely fitted so that it is rotatably supported. Note that this drive lever 418 is prevented from coming off by attaching a washer 423 to the tip of the shaft 422. One end of one side 420 of the drive lever 418 is extended, and the engaging portion 419 is provided protruding from the tip thereof. In addition, the drive lever 41
The other side 421 of 8 also extends in one direction, and one end of an operating lever 424, which will be described later, is rotatably connected to its tip. The drive lever 418 is connected to the cam gear 4
01 is not rotated, it is in the position shown by the solid line in FIG. 15, and as described above, the drive gear 324
When the second gear portion 326 meshes with the cam gear 401 and the cam gear 401 is rotated counterclockwise in FIG. 15, the grooved cam 417 rotates counterclockwise in FIG. This is the position indicated by the two-dot chain line in the figure. Here, at the other end of the operating lever 424,
As shown in FIG. 13, loading member 425
One end is rotatably connected. This loading member 425, as shown in FIG. 12b,
It is installed at the lower part of the loading path 301 in the figure, and the other end is rotatably supported by the mounting plate 402. The loading member 425 includes the operating lever 4.
A groove through which the disk 101 can be inserted is formed from the end connected to the bottom surface 4 to the approximate center thereof.
26 are provided. On the other hand, the loading member 425 is located on the bottom surface 427 of the loading path 301 on the downward right side in the figure.
Near the center of rotation with the mounting plate 402, the first
As shown in FIG. 2b, a locking portion 428 is formed which is cut approximately vertically. When the cam gear 401 is not rotated, the loading member 425 is at the position shown by the solid line in FIG. 12B. Therefore, the first loading mechanism section 30
The disk 101 transferred into the loading path 301 by 0 is placed on the bottom surface 426 of the loading member 425, and
28 and is temporarily stopped. When the cam gear 401 is rotated and the drive lever 418 is rotated counterclockwise in FIG.
25. Therefore, the loading member 425 is placed in the 12th position with the disk 101 placed thereon.
It is rotated clockwise in Figure b. Then, the bottom surface 426 of the loading member 425 is connected to the loading path 3.
01 (at this time, the center position of the disk 101 is at DC ₅ ), the disk 101 rolls under its own weight and falls into the disk pocket mechanism section 500 . Here, as shown again in FIGS. 15 and 22, a wall-shaped cam portion 429 is formed on the other surface of the cam gear 401. This cam part 429
As described above, when the cam gear 401 is rotated and the loading member 425 reaches the position where the disk 101 rolls out into the disk pocket mechanism section 500, the leaf switch 430 attached to the mounting plate 402 is activated. It is set to turn on. This leaf switch 430
is for detecting the end of the operation of the second loading mechanism section 400 , and this leaf switch 4
30 is turned on, the control circuit 910 controls the motor 3 of the loading unit 307.
A signal is output to 08 to reverse its rotation direction. Therefore, the cam gear 401 is rotated clockwise in FIG.
09 is removed from the recess 416, and the loading member 425 returns to its original position. Furthermore, the loading unit 307 includes a moving gear 31
9, 320 are rotated counterclockwise in FIG. 15, arrow L ₁
It is moved in the opposite direction and returned to its original position. Therefore, according to the second loading mechanism section 400 configured as described above, the loading path 3
By lifting the loading member 425, the disk 101, which has been temporarily stopped by hitting the locking portion 428 in
Since the disk 101 is rolled into the disk by its own weight, the disk 101 can be transferred very organically and reliably, and the configuration can be simplified. Further, since no external force is forcibly applied to the disk 101 itself to cause the transfer, no unreasonable force is applied to the disk 101, and safe transfer can be performed. Next, the disk pocket mechanism section 500 , disk pocket control mechanism section 550 , and disk playback mechanism section 580 will be explained in detail. That is, in FIG. 2, 501 is a partition plate provided between the loading path 301 and the unloading path 701, and a through hole 502 is formed in the partition plate 501 near the right side plate 13. In this through hole 502, a cylindrical support portion 50 constituting the disk pocket mechanism portion 500 is inserted.
3 is attached. First to fifth detectors 504 to 508 (see FIG. 1) for detecting the disk setting position are provided at predetermined intervals on the outer periphery of the front side of the support portion 503, and for driving the clamp mechanism. The engaging portion 509 has inclined both ends.
(see FIG. 1) is provided at a predetermined position. Also,
The support portion 503 has a guide groove 5 along its inner circumference.

The rotational force of this grinding gear 711 in the direction of arrow _L2 is transmitted to the unloading member 712 via the friction member 718 and to the actuating lever 721 via the friction member 720. For this reason, the unloading member 7
A rotation urging force is applied to the unloading roller 737 in the direction of bringing the unloading roller 737 into contact with the circumferential side of the disk 101 in the standby state, that is, in the direction of arrow _L3 in FIG. Further, a rotation biasing force is applied to the operating lever 721 in the direction of separating the locking portion 601 from the disk 101, that is, in the direction of arrow _L4 in FIG. Therefore, the disk 101 is released from the locking portion 601 and becomes movable in the direction of the tray portion 100 . Meanwhile, the rotational force of the friction member 711 in the direction of arrow _L2 is transmitted to the unloading roller 737 via the transmission gear 728, the unloading gear 738, and the shaft 736. Therefore, the unloading roller 737 is rotated in a direction that applies a rotational force to the disk 101 in the standby position in a direction in which it rolls onto the tray section 100 , that is, in the direction of arrow _L5 in FIG. Therefore, the unloading roller 737 is rotated in the direction of arrow _L5 , moved in the direction of arrow _L3 , and pressed against the peripheral side of the disk 101 in the standby position, so that the disk 101 rolls in the direction of the tray section 100 . It starts to come out. Then, the unloading roller 737 is moved in the direction of arrow _L3 so as to further push out the rolled disk 101, and as a result, as shown in FIG.

Then, when the disk 101 is moved in the direction of the tray section 100 and the center position of the disk 101 reaches the DC ₃ point as shown in FIG. The state will be as follows. At this time, the recess 747 formed in the cam portion 745 faces the micro switch 744, so the micro switch 744 is turned off. When the disk 101 is completely housed in the tray section 100 , the detection lever 743 is returned to the position shown in FIG. 29 by its own weight without the detection pin 746 touching the disk 101. Then, the micro switch 744 is turned on again by the action of the cam portion 745. When the micro switch 744 is switched from the OFF state to the ON state, the control circuit 910 detects that the disk 101 is completely accommodated in the tray section 100 and causes the motor 706 to reverse. control. Therefore, the unloading member 712 and the operating lever 721 are returned to the positions shown in FIG. 29, allowing the next unloading operation to be carried out.
