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. 18a, 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 ( a _first
(lower right in Fig. 8b) is formed. For this reason,
The disk 101 rolls along the above-mentioned inclination and is stored at the carry-in position IN in 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). In this playback position (PLAY), the center position of the disk 101 is moved to the DC ₇ point slightly above the DC ₈ point in FIG . It is said to be in a floating state. 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, and its center position is set at the DC ₈ point. . This unloading position OUT
is set between the loading position IN and the playback position (PLAY), and at the loading position OUT, the disk 101 is placed in the loading path 3.
01 is sent out to an unloading path 701 which is arranged in parallel with 01. This unloading path 701 is formed like a slit slightly wider than the thickness of the disk 101, similar to the loading 301, and also allows the disk 101 at the unloading position OUT in the disk pocket mechanism section 500 to be moved to the tray by its own weight. Part 1
An inclination (downward left in FIG. 18b) is formed that causes the wheel to roll out in the 00 direction. For this reason, disk 10
When the disk 1 reaches the unloading position OUT, it naturally rolls out of the disk pocket mechanism section 500 along the above-mentioned slope and enters 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. 18a.
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.
18 to the left in FIG .
It is sent to For this reason, disk 10
1 extends beyond the front edge 113 of the tray section 100 ,
It is stored in the tray section 100 and its center position is DC _10.
Points are made. 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 that accommodates 1012 disks. In other words, Figure 18a
The position of the disk 101 indicated by the middle dotted line corresponds to the 1013th disk from the position of the disk 101 indicated by the two-dot chain line in the figure. 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.
As described above, the movement of the tray section 100 at this time is controlled by the tray drive mechanism section 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 the tray section 100. This is done by driving 150 . 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. For this reason, the outlet section 70 of the unloading path 701 fills the groove that is empty after the disk 101 of the tray section 100 is taken out.
3 can be made to face each other. 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. Here, as is clear from FIG. 18a, the exit portion 703 of the unloading path 701
is formed to be narrower than the entrance portion 302 of the loading path 301, that is, to be slightly wider than the thickness of the disk 101. With this configuration, the disk 101 taken out from the tray section 100 can be quickly moved to the loading path 301.
When the disk 101 in the unloading path 701 is fed out by the unloading mechanism 700 ,
Since the disk 101 is accurately positioned to face the groove of the tray section 100 , the disk 101 can be accurately accommodated in the groove of the tray section 100 . In this regard, in particular, the intervals between the grooves of the tray section 100 are configured to be extremely narrow in order to accommodate as many disks 101 as possible. Therefore, if you do not position disk 1 as described above,
If an attempt is made to return the disk 101 to the tray section 100 , there will be problems such as the disk 101 being stored in a groove adjacent to the correct groove. Therefore, as mentioned above, unloading path 7
By configuring the outlet section 703 of the loading path 301 to be narrower than the inlet section 302 of the loading path 301, the disk 101 can be accurately positioned and the tray section 10
The disk 1 can be stored in the correct groove of the tray section 100, and the disk 1 taken out from the tray section 100 can be stored in the correct groove of the disk 1.
01 can be reliably transferred into the loading path 301. In the above manner, one disk 101 is transferred to the tray section 10.
The operation of taking out a plurality of disks 101 from 0, playing them, 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 , playing them, and returning them to the tray section 100 will be explained. First, a desired first disk 1 is selected from among the plurality of disks 101 housed in the tray section 100 .
01 is selected and pushed up from the tray section 100 , as described above, the first disk 101
are the first and second loading mechanism parts 300 , 4
00, it is transferred to the carry-in position IN in the disk pocket mechanism section 500 , and is moved to the playback position (PLAY).
is played. Here, for example, while the first disk 101 is being played back, 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, so that the plurality of disks 101 are automatically taken out from the tray section 100 one after another and played back, and then the disks 101 are loaded onto the tray section 100 again.
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. The series of operations in which a plurality of disks 101 are sequentially taken out from the tray section 100 , played, and returned to the tray section 100 are all performed by the operation section 90.
This is performed by the control circuit 910 sequentially controlling each mechanical part so as to have a predetermined time series based on the operation command signal from 0. 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
The function as a disk automatic changer device can be effectively enhanced. Above, we have explained how the disk 101 stored in the tray section 100 is recycled and returned to the tray section 100. However, as mentioned earlier, this disk autochanger device has A disk external loading/unloading mechanism section 800 that can carry the disk 101 in from the outside or carry it out after playback is completed.
is provided. That is, this disk external loading/unloading mechanism unit 800 , as shown in FIGS. 18a and _18b again, will be described in detail later. Mechanism section 50
0 to the carry-in position IN and the corresponding disk 101
The disc 10 at the unloading position OUT in the disc pocket mechanism section 500 can be regenerated.
1 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, or transports the regenerated disk 101 taken out from the tray section 100 to the outside, or The operation 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, but next we will explain the first and second loading mechanism sections 300 , 400 , the disk pocket mechanism section 500 , the disk pocket control mechanism section 550 , and the disk reproducing mechanism section. 580 , the disk temporary standby mechanism section 600 , the unloading mechanism section 700, and the disk external loading/unloading mechanism section 800 will be explained in detail. First, the first loading mechanism section 300 will be explained. That is, as shown in FIG. 1 again, the upper plate 14 and the left end side plate 12 have two substantially arch-shaped rods extending above the disk 101 housed in the tray portion 100 and along the periphery of the disk 101. Guide rails 303 and 304 are arranged in parallel in the depth direction of the tray section 100 . On the upper surface of the guide rails 303, 304 in FIG.
Teeth portions 305 and 306 are formed. A loading unit 307 is attached to the guide rails 303 and 304, as shown in FIG. 19 (the guide rail 304 is not visible in FIG. 19). 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. 20 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 sides 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 side surfaces 310, 311, and both protruding parts are provided with washers 317, 3, respectively.
Moving gears 319 and 320 are fitted through 18. And these moving gears 319, 320
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. 19 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. 19, 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 drive gear 324 in FIG. 20 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 drive 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. Further, the support body 309 has both sides 31 thereof.
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 rotatably fitted into the tip of the shaft 339. 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

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 clamp 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. 21. However, FIG. 21 shows the first loading mechanism section 300 viewed from the front side of the disk automatic changer device shown in FIG.
04, Moving gears 319, 320 and side surface 31
Since numbers 0, 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. The locking portion 35 has a substantially L-shaped side surface and is held so as not to fall downward in FIG. 21 with 339 as the center.
5 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 tray section 1
The loading pulley 352 is made not to come into contact with the disk 101 which has been pushed up from 00 and whose center position is set at _two points 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, and this leaf switch 356 is in the ON state (that is, the state in which the loading unit 307 is in the non-driving position).
Then, the control circuit 910 is in a state where it can output a signal for driving the loading unit 307. In this way, 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 rotational direction of this motor 308 is controlled so as to rotate the moving gears 319, 320 clockwise in FIG. 21. 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 is transmitted to the loading lever 343 via the friction member 345 after passing through the worm gear 327, the driving gear 324, the transmission gear 336, and the operating gear 342, and the loading gear 350 and the rotating shaft 348. The signal is transmitted to the loading pulley 352 via. The rotation direction of the motor 308 is determined by the moving gears 319 and 320.
21, the transmission gear 336 is rotated counterclockwise in FIG. 21, and the operating gear 342 is 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. 21 is transmitted to the loading pulley 352 itself. Therefore, when the loading unit 307 is moved in the direction of arrow _L1 in FIG. 21 and the loading lever 343 is separated from the locking portion 355,
The loading pulley 352, which rotates counterclockwise in FIG. 21, is pushed up from the tray portion 100 and comes into pressure contact with the disk 101, which is at _{the two} center positions 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. 18b, the disk 101 that has been pushed up from the tray section 100 is again rolled in the direction of 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. 21, 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 the 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. 18b. 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, since the rotating loading pulley 352 is brought into pressure contact with the outer circumference of the disk 101, the disk 1 to be selected is
01 by about 5 mm from the tray section 100 , it is possible to reliably take out the disk 101 distinguishing it from other disks 101, and there is no possibility that the wrong disk 101 will be taken out.
It is also suitable for downsizing. 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 35 of the loading pulley 352
Since the outer periphery of the disk 101 is sandwiched between the three spaces, the disk 101 can be stably transferred, and the disk 101 can also be positioned when it is guided into the loading path 301. This can further contribute to smoothing the loading operation. Further, the rotational force of the drive gear 324 is applied to the friction member 3
The rotating force of the moving gears 319, 320, that is, the loading unit 307, is transmitted to the friction plate 329 through a friction mechanism consisting of a spring 332 and a spring 332. , 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.
The disk 101 can be transferred safely without applying excessive force to the disk 101. 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 too, it is ensured that no unreasonable force is applied to the disk 101. Furthermore, as is clear from FIG. 20, the diameter of the transmission gear 336 is smaller than the diameter of the second gear portion 326 of the drive gear 324. Therefore, the degree of rotation of the transmission gear 336 is the same as that of the drive gear 32.
It is faster than the rotation speed of No. 4, that is, the speed has been increased. The diameter of the transmission gear 336 and the diameter of the first gear portion 340 of the operating gear 342 are approximately the same, and the diameter of the second gear portion 340 of the operating gear 342 is approximately the same.
The diameter of the loading gear 350 is approximately the same as the diameter of the loading gear 350. Therefore, the rotational speed of the loading 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 portion of the loading pulley 352, that is, the circumferential speed, is faster than the circumferential speed of the moving gears 319 and 320. It is done like this. Therefore, after the disk 101 is rolled by the rotational force of the loading pulley 352 itself, the loading unit 307 follows the disk 101.
will now be moved. Therefore, the loading unit 307 does not move farther 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.

This can contribute to promoting downsizing. The second point is that the disk pocket member 511
The first and second disks carry in, play, and take out the disks.
Another advantage is that the third position is rotatably controlled to move in and out (forward and backward) so that the disk playback position also serves as the disk loading and unloading position. In other words, this is to reliably prevent the disc 101 from moving in and out of the disc pocket member 11 when the disc 101 is in the playback state, and to ensure that the operation of the disc pocket mechanism section 500 can be controlled as reliably as possible. This makes it possible to make a contribution. The third point is that a clamper holder 518 is provided at the point where the disc pocket mechanism 500 can be rotated in and out (forward and backward), which takes the first, second, and third positions for loading, reproducing, and unloading the disc. Another advantage is that the clamper holder 518 is configured to be interlocked with the second position taken by the disk pocket mechanism section 500 . In other words, by interlocking the clamper part 519 of the clamper holder 518 at the second position taken by the disposable mechanism part 500 , the operation of the clamper holder 518 can be controlled as reliably as possible. This makes it possible to contribute to the The fourth point is that the opening 5 of the pocket portion 513
14, the guide portion 515 is configured such that the disk 101 rolls under its own weight. In other words, when the disk 101 is sent out from the pocket section 513 to the unloading path 701 and the disk external unloading path 802, the disk 101 is rolled and sent out by the guide section 515, and the operation of the disk 101 can be controlled reliably. It will be possible to contribute to making it possible to achieve the goals. Note that the guide portion 515 provided in the opening 514 of the pocket portion 513 is formed into a step-like shape so that the disk 101 rolls under its own weight, and the loading path 301, the unloading path 701, the disk external carrying path 801, and the It is also effective to configure the disk 101 so that it can be moved in and out in a state corresponding to the disk external carry-out path 802, respectively. As shown in FIG. 5, an external disk loading/unloading member 806 is provided outside the tray section 100 for supplying internal disks as a receiving section for loading/unloading external disks. In other words, this serves as a disk holder when the disk 101 is brought in and taken out from the outside, and can contribute to improving the handling of disks from the outside as much as possible. . Next, the disk 101 rolled out from the disk pocket mechanism section 500 as described above is
The disk temporary timing unit 600 that temporarily waits within the unloading path 701 and the unloading mechanism unit 700 that returns the temporarily held disk 101 to the tray unit 100 will be described. That is, as shown in FIG .
The disk 101 that has been rolled out into the unloading path 701 is brought into contact with the substantially cylindrical locking portion 601 and placed in a standby state within the unloading path 701 . Here, the locking part 601 is connected to an unloading mechanism part 700 . That is, in FIG. 29, a frame 704 is fixed to the upper plate 14 (not shown in FIG. 29). A motor 706 is attached to this frame 704 via a fixture 705, and a worm gear 708 is attached to a rotating shaft 707 of this motor 706.
is fitted. And this worm gear 7
08 is meshed with a drive gear 709 rotatably supported by the frame 704. Further, the drive gear 709 is meshed with a friction gear 711 of an unloading unit 710. FIG. 30 shows details of this unloading unit 710. In the figure, 712 is an unloading member formed by bending a metal plate into a substantially U-shape. This unloading member 71
Both side surfaces 713 and 714 facing each other extend in the same direction, and one of the side surfaces 713 and 714 of
The distal end portion in the extending direction of 14 is formed into a substantially disk shape and serves as a friction portion 715 . A shaft 717 is loosely inserted into a through hole 716 formed in the center of the friction portion 715 of the unloading member 712 from outside the friction portion 715 . This shaft 717 includes a friction member 718 formed in a ring shape of felt, etc., and the friction gear 7.
A through hole 719 formed at the center of the unloading member 712, a ring-shaped friction member 720, a through hole 722 formed at one end of the operating lever 721, and a coiled spring 723 are loosely inserted into the side surface of the unloading member 712. It is loosely inserted into a through hole 724 formed in 713, and an E ring 725 is fitted to its tip to prevent it from coming off. Here, a portion of the shaft 717 that protrudes outward from the friction portion 715 of the unloading member 712 is fixed to the frame 704.
Therefore, the unloading member 712 is supported so as to be rotatable about the shaft 717 with respect to the frame 704. Also,
The friction gear 711 is rotatable about a shaft 717, and the operating lever 712 is rotatable about a shaft 717. Further, the friction portion 715, friction members 718, 720, friction gear 711, and operating lever 721 of the unloading member 712 are pressed against each other by a spring 723. The locking portion 601 is attached to the other end of the operating lever 721. Note that even if the unloading member 712 is rotated about the shaft 717, the drive gear 7
09 and the friction gear 711 are of course meshed with each other. Further, from the outside of one side surface 713 of the unloading member 712, a shaft 727 is loosely inserted into a through hole 726 formed in the center of the side surface 713. This shaft 727 is loosely inserted into a through hole 729 formed in the center of the transmission gear 728, and is loosely inserted into a through hole 730 formed in the other side surface 714. E-rings 731 and 732 are fitted onto portions of the shaft 727 that protrude outward from both side surfaces 713 and 714 of the unloading member 712, respectively, to prevent them from coming off. Here, the transmission gear 728 has a first gear part 733 with a small diameter and a second gear part 734 with a large diameter, and this first gear part 733 is meshed with the friction gear 711. It is something that exists. Further, from the outside of one side surface 713 of the unloading member 712, a shaft 736 is loosely inserted into a through hole 735 formed at the base end of the side surface 713. An unloading roller 737 is attached to a portion of the shaft 736 that protrudes outward from the side surface 713. And the above shaft 7
36 loosely inserts an unloading gear 738,
It is loosely inserted into a through hole 739 formed on the other side surface 714, and an E ring 740 is fitted to the tip thereof to prevent it from coming off. Further, the unloading gear 738 is fixed to the shaft 736 by a screw 741 so as to rotate integrally with the shaft 736. This unloading gear 738 is meshed with the second gear portion 734 of the transmission gear 728. Here, as shown in FIG. 29 again, a shaft 742 is implanted at a predetermined position on the mounting plate 402, and one end of a detection lever 743 is rotatably supported by the mounting shaft 742. There is. This detection lever 7
A cam portion 745 that can be engaged with and disengaged from a micro switch 744 attached to the frame 704 is formed at the pivoting base end of 43. Note that this micro switch 744 is for detecting that the disk 101 is housed in the tray section 100, and its details will be described later. Further, a detection pin 746 is implanted at the other end of the detection lever 743 so as to be substantially parallel to the locking portion 601 . Unloading mechanism section 7 configured as above
00, its operation will be explained below. first,
When the disk 101 that has finished playing is rolled out from the disk pocket mechanism section 500 into the unloading path 701 as described above, the disk 10
1 is stopped when it hits the locking portion 601, and is placed in a temporary standby state. Then, the next disc 101 to be reproduced is taken out from the tray section 100 and transferred into the disc pocket mechanism section 500 for reproduction. During this reproduction, the motor 706 is rotationally driven by the sequence control of the control circuit 910. The rotational force of this motor 706 is applied to the drive gear 709
is transmitted to the friction gear 711 via. At this time, the rotation direction of the motor 706 is determined by the friction gear 711.
is controlled to rotate in _{the two} directions indicated by arrow L in FIG. The rotational force of the friction 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, which is rotated in the direction of arrow _L5 , is moved in the direction of arrow _L3 and comes into pressure contact with the circumferential side of the disk 101 in the standby position, so that the disk 101 is moved to the tray section 100.
It starts to move in the same direction. 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.
1 is returned to the tray section 100. Here, when the disk 101 is moved from the standby position toward the tray section 100 as described above, the circumferential side of the disk 101 touches the detection pin 74.
6, the detection lever 743 moves in approximately the same direction as the actuation lever 721, that is, in the direction indicated by the arrow L ₄ in FIG.
rotated in the direction. Here, the detection lever 743 is in the 29th position.
When in the position shown in the figure, the cam portion 745
The micro switch 744 is turned on by this action. Then, when the disk 101 is moved toward the tray section 100 and the center position of the disk 101 reaches the DC ₃ point as shown in FIG. 18b again, the detection lever 743 is rotated most clockwise in the figure. The state will be as follows. At this time, the cam portion 7
Since the recess 747 formed in 45 faces the micro switch 744, 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. and,
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 controls the motor 706 to rotate in the reverse direction. do. For this reason,
Unloading member 712 and actuation lever 72
1 is returned to the position shown in FIG. 29, and is ready for the next unloading operation. Therefore, the disk temporary standby mechanism section 600 and the unloading mechanism section 7 configured as described above
According to 00, disk 101 that has finished playing first
Since the disc 10 is made to temporarily wait in the unloading path 701, the next disk 10 is
1 can be played back and the disk 101 can be returned to the tray section 100 during this playback, so that the playback interruption time can be shortened as much as possible and the disk 101 can be replaced quickly. In this case, the disk automatic changer device described here causes the disk 101 to take different paths during loading and unloading. A standby section is provided, and the disk 101 is placed in the standby section.
Of course, the same effect can be obtained even if the next disk 101 is loaded via the above route while the next disk 101 is on standby. Further, according to the disk temporary standby mechanism section 600 , since the movement of the disk 101 is prevented by the locking section 601, the configuration is extremely simple and there is no need to apply excessive force to the disk 101. It's nothing. On the other hand, according to the unloading mechanism section 700 , the rotating unloading roller 737 is moved so as to push out the disk 101.
Since the discs 101 are brought into contact with the discs 101 and pushed into the tray section 100 , the other discs 101 stored in the tray section 100 are not affected in any way.
This allows the disk 101 to be reliably stored in the tray section 100 . Also, disk 1
01 is stored in the tray portion 100 while rolling, so that it can be easily and smoothly stored into the disk 101. Furthermore, the detection lever 743 directly
01 and is moved, the disk 101
It is possible to reliably and accurately detect that the paper is stored in the tray section 100 . It goes without saying that this invention is not limited to the embodiments described above and illustrated, and that various modifications and applications can be made without departing from the gist of this invention. [Effects of the invention] Therefore, as detailed above, according to this invention, it is possible to increase the number of disks that can be stored with as little space as possible, and it can also contribute to improving the disk replacement speed. Thus, it is possible to provide an extremely good disk autochanger device that satisfies the requirement of reliable operation with a simple configuration.
