FIGS. 8(a), 8(b), and 8(c) are a sectional front view, a front view, and a left side view showing details of the tray body 103 in the above, in which the radius of curvature R1 suitable for the disc 101 to be stored is shown. A large number (50 in the illustrated case) of storage grooves 102 in the shape of an approximately i semicircle as described above having valleys and peaks having a radius of curvature R2 smaller than R1 are arranged at a predetermined pitch in the depth direction (1 degree in the illustrated case). For CD with 2 fin thickness, it is continuously formed with 3 pieces, the width of the valley is 1.3, and the width of the crest is 2.2 pieces (widening at the end), and the above R1

~I(s') are held in a positionally regulated state by holders 177.

In this case, the holder 177 has slits SL1 to SL8 formed in front of the holding holes H1 to H8 as shown in FIG.
The width of SL is 0.5m+a, and the width of other SL
It is narrowed to half the value of the 3-5LsO width (1 謔).

In addition, these slits SL1 to SLs are connected to each sensor 81 to
As shown in FIG. 11 as a representative example, the sensors S8 face each other with both the light emitting part (LED) and the light receiving part (P, T) of each of the sensors S1 to S8, which are arranged in a substantially semicircular shape. It is formed by relationships.

Then, the sensor S1*S of the one above! The output is for positioning and is connected in a differential Wb configuration as shown in FIG. That is, both these sensors S1, S

It is configured to control 72.

Additionally, sensors 5s to 8s other than those mentioned above are for reading addresses.

Figure 13 shows the access reflector plate 11) g
This shows the details of the upper two reflection patterns pltp.
, are for positioning, and both correspond to each storage groove 102 of the double-hole tray main body 103, respectively.
In this case, 50 pieces are each formed on both sides, with 25 pieces wrapped.

In addition, in Figure 13, the other nine turns of reflection P3 to P8
Addresses 1 to 50 corresponding to each storage groove 102 of the tray body 103 described above are formed in binary notation.

One! f, the above-mentioned light reflection sensor section 174 is attached to the reflection plate 10 like the above-mentioned 7-, which is attached to the back part of the tray main body 103.
After reading reflection patterns P3 to Ps''k giving addresses 1 to 50 with sensors S3 to S8 for B, the tray unit 100 is moved via the tray drive mechanism unit 150 so as to reach a predetermined access position. , sensor S1 18
2, it is possible to accurately position it with an accuracy of 0.25 (±0.125).

FIG. 14 shows a state in which the tray section 100 described above is assembled into the tray drive mechanism section 150, and the disk selection mechanism section 200 is also shown. However, the tray part 10
0 indicates one disk 101 located at a predetermined position (positioning position of the above-mentioned sensors S1 to Ss) that should be accessed for convenience of illustration.
Please only illustrate.

Here, the 1-disk selection mechanism section 200 includes a motor 201 which is turned into a driving state after the tray section is moved to a predetermined access position by the tray drive mechanism section 150 as described above, and a motor 201 which will be described later from the motor 201. Transmission mechanism 20
2, and a positioning shaft portion 203 and a disk push-up lever portion 204 that are driven via the lever 203.

15(a), (b), and (e) show details of the disk selection mechanism section 200. When the motor 201 is driven, the pinion gear 220 fixed to the output shaft of the motor 20 is shown in FIG. Rotate counterclockwise.

By this, the above transmitter'! ! Clockwise rotation is transmitted to the cam gear 207 via reduction gears 205 and 206 that constitute Q202.

In this case, the cam gear 207 is as shown in the figure (d) e (e)
# It has first to third cam portions 2θ8, 2θ9, and 21o as shown separately in (f).

Of these, the third cam part 210 is for regulating the rotation angle of the cam gear 207 by coming into contact with a bent part 212 formed on the mounting plate 21 of the disc selection mechanism part 200, and is used to control the rotation angle of the cam gear 207. It is designed so that it cannot rotate clockwise.

Then, as the cam gear 207 rotates clockwise, the first cam portion 20B first pushes the shaft pushing lever 213 onto the support shaft 214.
The distal end thereof is bent so as to push the rear end of the positioning shaft 215.

This positioning shaft 215 is pressed toward the shaft pushing lever 213 by a spring 216 and a retaining ring 217 provided on the positioning shaft 215.

As a result, when the shaft pushing lever 213 is rotated by the first cam portion 20B and the positioning shaft 215 is pushed out in the direction of the arrow, the tip portion formed in the shape of a chi-9 moves to the position of the tray portion 100 described above. The corresponding hole 123 formed in the ejecting member 110 enters.

As a result, the above-mentioned accelerator position accuracy of the tray section 100 can be obtained by the light reflection sensor section 1-74 within ±0.
Even higher accuracy is obtained from 125 m, but the fitting clearance between the idle hole 123 and the positioning shaft 215 is 0.01 to 0.03.
You will be able to do it within wa.

In this case, by increasing the force for pushing out the positioning shaft 215, it is possible to overcome the frictional force of the tray drive mechanism section 150 and correct the position of the tray section 100.

Then, when the cam gear 207 further rotates, the second cam part 209 presses the lever 2111 and the lever 218
Rotate counterclockwise.

Here, the tip of the lever 218 is connected to the tray portion 100 mentioned above.
Each lever 104 of the push-up lever mechanism 106 incorporated in
The disk selection mechanism section 200 is disposed in such a position that it can engage with the base end of the disk.

As a result, the lever 218 is moved from (-) to (,) in FIG.
Then, as shown in FIG. 17, 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 rotated to the position indicated by the chain line. Since the disk can be pushed up about 5 degrees from the position shown by the solid line, it becomes possible to select only the target disk accessed here.

The actual selection completion state is when the cam gear 207 rotates further and the third cam portion 210 comes into contact with the bent portion 212 as shown in FIG. 16(e).

The disk selection mechanism section as described above also functions as a disk selection operation and a mutual locking operation of the tray section.

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 features of the above-mentioned tray section JOO, tray drive mechanism section LL, and disk selection mechanism section 200 will be explained.

Regarding the tray section 100, the first point is regarding the structure of the tray body 103, which has a storage groove 102 that holds approximately one semi-circumferential portion of the disk 101, and has a storage groove 102 that holds approximately one half circumference of the disk 101. Guide groove 1 for loading and unloading disc 10 at a high position
14.

In other words, by having such a structure, the disk 101 housed in the tray portion 10Q is prevented from moving unless an external force is applied.
Misalignment due to vibration etc. is prevented,
This is because it becomes possible to always access the desired disk 101 and contribute to reliable loading.

The second point is that the tray part 100 has a storage groove 102 for the disk 101, whereas the tray body 103 has a storage groove 102 for the disk 101.
The disk pushing mechanism 106, which has push-up grooves 115f corresponding to the respective disks 101f and can push up each desired disk 101f, is integrally constructed.

In other words, this means that the tray section 100 can accommodate as many discs 101 with as little volume as possible.
This is because it can contribute to bringing the desired disk 101f into a state in which it can be reliably rotated.

The third point is that the tray section 100 is the target disk JO.
As a final positioning reference portion for 1f access, for example, it may include an id hole 123 formed at a pitch corresponding to the storage groove 102 of the disk 1θ1.

In other words, this can contribute to further improving the access accuracy based on the electrical signals by the tray drive mechanism section 150.

Note that the final positioning of the tray section 100 referred to here refers to the positioning of the tray drive mechanism section 150 after the tray drive mechanism section 150 has positioned the tray section 100 based on the electrical signal from the light reflection sensor section 174 as described above. This means that the tray section 200 can be positioned more accurately by overcoming friction. Specifically, this is achieved by pushing the tip i4 portion of the positioning shaft 215 into the hole 123 of the positioning member 110 to correct the position of the tray portion 100.

The fourth point is that the tray part J is configured to be freely attachable and detachable, and in particular, the structure is such that accuracy when attached to the tray drive mechanism part 150 can always be ensured.

This is because it is possible to load or replace the disks 101 with the tray section removed from the main body of the device.The more disks 101 to be stored, the more It is something that can be very powerful.

The fifth point is related to the light reflection sensor section 174 for access in the tray drive mechanism section 150, and is the front part of the sensors S1 to S8, which have a light emitting section (LED) and a light receiving section CP, T). One point is that the SLI to 15L8 are positioned so as to be able to face both the light emitting section (IJD) and the light receiving section (P, T).

Normally, the slit is provided so that it faces only the light-receiving part of the sensor, but in order to improve access accuracy, it is better to provide the slit so that it faces both the light-emitting part and the light-receiving part of the sensor. This is because it is advantageous.

In this case, access accuracy can be further improved by making the slit width narrower in the slit facing the positioning sensor than in the absolute address reading sensor.

The sixth point is the light reflection sensor section 17 for access as well.
Regarding point 4, is there a reflection for positioning? Turn P1. P2 is a predetermined minute distance (for example, 0.25 m)
The reflection f-turn P1*
P! One point is that each output of the positioning sensor 51eB that reads the snow has a differential configuration.

In other words, access is controlled by the tray drive mechanism section 150f using the error signal calculated from the output between the positioning sensors S1 and 82, so the access (positioning) accuracy is controlled by the error signal calculated from the output between the positioning sensors S1 and 82. This is because it is possible to achieve high accuracy within a very small distance (for example, 0.25 square meters) for lapping.

The seventh point is related to the disk selection mechanism section 200, and includes a positioning shaft section 2θ3 that performs final positioning with respect to the tray section 100 and a disk push-up that performs push-up to select the target disk 101. The lever part 204 and the disk selection part use the same power source as the motor 20.
1 to the mounting plate 211 in an interlocking relationship with a predetermined timing via the transmission mechanism 202.

In other words, 1. This can contribute to reliably and smoothly perform a series of functions, including the final positioning of the tray section 100 and the intended pushing up of the disk 10, and is constructed by using the same power source. This is because it can contribute to the simplification of the system, and furthermore, by making it into a unit, it can also contribute to convenience in handling as fine adjustments of each part can be made as necessary before assembling the device into the main body of the device.

The eighth point is also related to the disk selection mechanism section 200, and is that the accessed target disk 101 is selected by slightly pushing up only the disk 101 from the storage position of the tray section 100. It will be done.

In other words, when a large number of disks are stored in the tray section 100 using as little volume as possible, only the desired disk can be selected without fail even though there is not much space between the stored disks. This is because it can contribute to creating a state suitable for loading.

Next, the disc 101 selected from the tray unit 100 as described above is transferred to the disc pocket mechanism unit 500 via the first and second loading mechanism units 30 (h400), as described above. It will be played. And,
After the reproduction is finished, the disc 101 is returned to the tray unit 100 via the disc temporary standby mechanism section 700 and the unloading mechanism section 700.

Here, the first and second loading mechanism sections 300
．． Before explaining the details of 400, we will briefly explain the overall movement process of the disk 101 during loading and unloading.

That is, FIGS. 18(a) and 18(b) show the movement of the disk 101 from the top side and the front side of the disk autochanger device previously shown in FIG. 1, respectively. In addition, Fig. 18 (a) and (b)
, DCl to DCl are respectively disks 10
Figure 18 (&) # (
b) It is assumed that disks 101 shown with the same symbol in between are shown to have the same center position.

First, in FIGS. 18A and 18B, when the disk 101 is stored in the tray section 100 as described above, the center position of the disk 101 is D C1 in the figure.
Disk 1 is placed in the position shown in the figure and 1 above.
01, when the tray section 100 is pushed up by the disk selection mechanism section 200, its center position is shifted to the above D.
DC2 directly above the Cl point is moved completely.

Then, due to the action of the control circuit E)10,
The first loading mechanism section 300 starts to be driven. This first loading mechanism section 300 includes a tray section 100.
The disk 101 that has been pushed up is rolled to the right in FIG. 18 and taken out from the tray section 100.

Then, with this first loading mechanism section 100,
The rolled disk 101 is first placed in the tray section 100.
The center position is moved to the DC3 point, and the loading path 301 (see FIG. 18(&)) provided between the tray section 100 and the disc pocket mechanism section 500 is be transported.

This loading path 301 is formed in the form of a slit that is slightly wider than the thickness of the tray section 101.
An entrance portion 3 into which the disk 101 taken out from the
02 has a wide tapered opening as shown in FIG. 18(a), so that the disk 101 can be easily inserted into the opening. Then, the disk 101t transferred into the loading path soi by the first loading mechanism section 300 is stopped within the loading path 301, and its center position is set as a point DC.

When the disk 101 is stopped in the loading path 30 in this way, the first loading mechanism section 30
0, the second loading mechanism section 40
0 starts driving. This second loading mechanism section 4
00 lifts up the disk 101 stopped in the loading path 301 and moves its center position to point DC.

Here, the loading path 301 has a center position D
An incline (FIG. 18) is formed that allows the disk 101 moved to point C5 to roll out under its own weight and send it out to the loading position (IN) inside the disk pocket mechanism section 500. Therefore, the disc 101 falls on the above-mentioned inclination and is stored in the loading position (IN) in the disc pocket mechanism section 500, with its center position being a point DC.

Then, the 1-disc pocket control mechanism 550 is started to be driven by the action of the control circuit 910, and the 10th disc passes through the unloading position (OUT) and moves to the playback position (
PLAY).

At this playback position (PLAY), the disc 101
The center position is slightly higher than the DC point above in Figure 18 (b
) It is moved to the DC point of the middle upper force, and is completely floating without touching anywhere inside the disk pocket mechanism section SOO. In this state, the disk 101 is
The disk is rotated and played back by a disk playback mechanism section 580.

When the playback operation is completed in this state, the disk deck control mechanism 550 is driven again by the action of the control circuit 910, and the disk 10 is moved to the unloading position (
OUT), and its center position is set as point DC. This carry-out position (OUT) is the carry-in position (
This is set between the playback position (PLAY) and the playback position (IN), and the disc 1 is
0 is delivered to an unloading path 701 which is arranged in parallel with the loading path 301.

Like the loading path 301, this unloading path 70 is formed like a slit that is slightly wider than the thickness of the disk 101.
A slope (downward to the left in FIG. 18) is formed to cause the disk 101 at the unloading position (OUT) in 00 to roll out in the direction of the tray section 100 due to its own weight. Therefore, when the disk 10 reaches the unloading position (OUT), the disk pocket mechanism section 50 naturally moves along the above-mentioned slope.
0 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 open in the shape of a chi A' as shown in FIG. 18(a). The disc 10 is designed to be easily inserted. The disk 10 that has fallen into the unloading path 70 is temporarily held in the unloading path 701 by the disk temporary standby mechanism section 600, and its center position is set at DC.
Scored 9 points.

This temporary standby state of the disk 101 in the unloading path 70 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 is configured to operate a disk 101 in a standby state within an unloading path 701.
The paper is rotated to the left in the figure and fed into the tray section 100. Therefore, the disk 101 is accommodated in the tray section 100 beyond the front edge 113 of the tray section 100, and its center position is set as the DC1o point.

Here, the disk 101 takes different paths during loading and unloading. Specifically, in terms of the number of disks 101 stored in the depth direction of the tray section 100, there are 1012 disks between the disk 101 in the loading path 301 and the disk 10 in the unloading path 701. There is an interval in which . In other words, Figure 18 (
a) The position of the disk 101 indicated by the dotted line in the figure is from the position of the disk 101 indicated by the two-dot chain line to the disk J 0
This corresponds to the 13th image.

For this reason, this disc autochanger device
- First, select the desired disk 1 using the disk selection mechanism section.
When selecting 01, the disk 101 to be selected by the tray drive mechanism is moved to the loading path 3.
The tray section 100 is moved so as to face the population section 302 of No. 01. As described above, the movement of the tray section 100 at this time is performed by the tray drive mechanism section in accordance with the control of the control circuit 910 based on the address (that is, disk access information) added corresponding to the name groove of the tray section 100. This is done by driving 150.

Then, the disk 101f selected in this way,
When returning from the unloading path 70 to the Radley section 100, the control circuit 910 operates to select the tray N corresponding to the disk access information based on the disk access information used to move the tray section 100 previously. The tray section 100 is completely automatically moved to a position shifted by the 1013th disk from the 100th position. For this purpose, the groove which becomes empty after the disk 101 of the tray section 100 is taken out is made with 75 beads so as 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 70 is such that the disk 10 is moved into the unloading path by the disk temporary standby mechanism section 600. It is designed to be executed when the program is on standby in 701. For this reason, the tray section 100 is
The disk 1oxtd,s that was sent out is returned to the groove of the tray section that was first taken out, and the desired disk 101 is selected from the tray section 100, played back, and the tray section receives 1000 yuan. The operation of returning it to the groove is completed.

Here, as is clear from FIG. 18(,), the outlet portion 703 of the unloading path 701 is narrower than the inlet portion soz of the loading path 301, and the thickness of the tamping disk 10 is also slightly wider. It is formed. With this configuration, the disk 101 taken out from the tray section 100 can be quickly transferred to the loading path 3.
01, and the disk 101 in the unloading path 701 is positioned so as to accurately face the sea of the tray section 100 when being fed out by the unloading mechanism section 700. Therefore, the disk 101 can be accurately accommodated in the groove of the tray section 100.

In this regard, in particular, the spacing between each groove of the tray portion 100 is
In order to accommodate as many disks 101 as possible, it is configured to be extremely narrow.

Therefore, without positioning as described above, the disk 1
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 described above, by configuring the outlet portion 703 of the unloading path 70) to be narrower than the inlet portion 302 of the loading path 301, it is possible to accurately position the disk 101 and store it in the correct groove of the tray portion W. In addition, the disk lθ1 taken out from the tray section 100 can be reliably transferred into the loading path 301.

Above, we have explained the operation of taking out one disc 101 from the tray section 100, playing it, and returning it to the tray section again. The operation of returning to section 100 will be explained. First, when a desired first disk 101 is selected from among the plurality of disks 101 stored in the tray section 100 and pushed up from the tray section μ,
As mentioned above, the first disk 10 is located at the loading position (IN) within the first and second load kerato mechanism sections 500.
and is played back at the playback position (PI, AY).

Here, for example, during playback of this first disc 101,
Next, the tray unit 100 is accessed to the second disc 101 to be reproduced, and the tray unit 100 is moved to a position where the second disc 101 faces the entrance 302 of the loading path 301. . However, even if this access operation is completed, the second disk 10
1 has not been pushed up from the tray section 100 yet.

After the playback is completed, the first disc 101 is sent out from the unloading position (OUT) at the time of unloading 701, and the first disc 101 is placed in a standby state by the disc temporary standby mechanism section 600. When the disk 101 is in the standby state, the second disk 10 is pushed up from the tray section 100 where the access operation has been completed, and then the first and second loading mechanism sections SOO.

400, the disc is transferred to the loading position (IN) in the disc pocket mechanism section 500, and is played back at the playing position (PLAY). During playback of the second disc 101, the tray section 100 moves the groove in which the first disc 101 was stored into the exit section 703 of the unloading path 701.
is moved to face the After that, it is in standby state. Then, while this second disc 101 is being played back, the tray section ioo performs an access operation to the third disc 101 to be played next, and the same operation is repeated thereafter, resulting in a plurality of An operation is performed in which the disks 101 are automatically taken out one after another from the tray section ioo, played back, and returned to the tray section 100 again.

In addition, in the above, while the first disc 101 is being played, the tray unit 10 is moved to the second disc 10 to be played next.
Although the explanation has been made so that the access operation of the tray section 100 is performed, the access operation of the tray section 100 is performed as follows:
0 may be performed while the unloading path 701 is temporarily on standby.

The series of operations in which the plurality of discs 101 are sequentially taken out from the tray section 100, played, and returned to the tray section 100 are all performed by the control circuit 910 for each mechanism based on the operation command signal from the operation section 900. This is done by sequentially controlling the sections so that they have a predetermined time sequence. Therefore, as described above, the tray section 100 (7
) Whether the 7-access operation is performed while the first disc 101 is being played or when the first disc 101 is in a standby state can be selected by appropriately setting the sequence control function of the control circuit 910. It is possible to do so.

As described above, in this disc autochanger device, the disc 101 is caused to pass through different routes (loading path 301 and unloading path 20) during loading and unloading, and the first Disc Jl)J is temporarily put on standby when unloading, and during this waiting, the next second disc 101 is taken out from the tray section 100 and played back, and while this second disc 101 is being played back, the first disc 101 is Since the disk is returned to the tray section 100, the time from the end of playback of the first disk 101 to the start of playback of the second disk 101, which is the so-called loading tip, can be shortened. It is possible to effectively enhance the function of the device.

Above, we have described how the disc 101 stored in the tray section 100 is squared and returned to the tray section 100. However, as mentioned earlier, the disc 101 to be played is brought in from outside to this disc autochanger device. A disk external loading/unloading mechanism section SOO is provided which can carry out the loading and unloading of the disk 101 to the outside after the completion of tIJ recording. That is, this disk external loading/unloading mechanism section SOO, which will be described in detail later, loads the disk 101 (center position DC 11 point) from the outside of the disk autochanger device, as shown in FIGS. 18(,) and (b) again. The disk 101 placed in the carry-in position (IN) in the pocket mechanism section 500 can be played back, and the disk 101 in the carry-out position (OUT) in the disk pocket mechanism section 500 can be played outside (center position DC, 2 points). ).

Therefore, in this disc cart changer device,
In addition to reproducing and returning the disc 101 stored in the tray section 100, it is also possible to reproduce the disc 101 brought in from outside and transport it to the outside, or to remove the disc 101 from the tray section 100.
The operation of the control circuit 910 also serves as a bow section when the disc 101 that has been taken out and played is carried out to the outside, or when the disc 101 that has been brought in from the outside and played back is stored in the tray section 100. It is something. in this case,
While disc 101 is being played, is disc 101 designated as the disc from the outside? As long as the disc 101 is not carried into the pocket mechanism section 500 and is sent out to the unloading path 701 or outside after the end of the pick-up playback, the disc 101 is not carried into the disk pocket mechanism section 5 from the outside.
00.

The overall movement process of the disk 101 has been described above, but next, the first and second loading mechanism sections 300, 400. Disc pocket mechanism part ξ00,
Disc pocket control mechanism section 550, disk playback mechanism section 580, disk temporary standby mechanism section [su, unloading mechanism section 700, and disk external loading/unloading mechanism section 80]
The details of 0 will be explained.

First, the first loading mechanism section 30θ will be explained. That is, as shown again in FIG. The two guide rails 303, 3
04 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.

The guide rails 303 and 304 have a 19th
As shown in the figure (the guide rail 304 is not visible in FIG. 19), a loading unit 307 is attached. This loading unit 307 is configured to move in one direction and the other direction on the guide rails 303 and 304, respectively, by rotating a built-in motor 308 in the normal and reverse directions.

FIG. 20 shows the structure of this loading unit 30'1. 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 opposite sides 310 and 311 of this support body 309, respectively.
, 315 are fitted respectively. In this bearing, a rotating shaft 316 is rotatably inserted into the members 314 and 315. Both ends of this rotating shaft 316 also protrude outward from both side surfaces 310 and 311 of the support body 3090, and washers 317 and 31 are provided at both protruding portions, respectively.

Here, on the outer surface of one side 310 of the support body 309, as shown in FIG.
Cylindrical guide portions 321 to 3 that are in contact with 3 on opposite sides
23 is attached. 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. The guide parts 321 to 323 on one side 310 of this support body 309, the guide 9 part on the other side 311, and the moving gears 319, 320
Due to this action, the loading unit 307 is supported by the guide rails 303 and 304.

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 of the rotation shaft 316. Further, on the circumferential side of this drive gear 324, first and second gear parts 325 and 32 are provided.
6 are formed respectively. The first gear portion 325 includes a rotation shaft (not shown) of the motor 30B.
A worm gear 327 fitted on the worm gear 327 is meshed with the worm gear 327.

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 that is disengaged from the outer periphery toward the center of the friction plate 329 to the rotating shaft 316. It rotates integrally with the rotating shaft 316.

Further, a recess 331 is formed approximately at the center of the right end surface of the driving gear 324 in FIG.
A coil-shaped spring 332 is loosely fitted within 31. This tin ring 332 has one end located in the recess 33.
A ring-shaped spring holder is positioned by a washer 333 whose other end is fixed to the rotating shaft 316 and is in contact with the plate 334, and the drive gear 324 and the friction plate 329 are connected to each other. are urged to be pressed against each other via a friction member 328.

Therefore, when the motor 30B is driven in forward and reverse rotation, the rotational force is applied to the worm gear 327, the drive gear 324, the friction member 328, the friction plate 329, and the rotating shaft 31.
6 to the moving gears 319, 320,
When the moving teeth 31y, s;to are rotated in the forward and reverse directions, the loading unit 307 is moved in one direction and the other direction on the guide rails 303 and 304. .

Here, a shaft 335 is provided on the side surface 31 of the support body 309.
One end of is fixed. A transmission gear 336 that meshes with the second gear portion 326 of the drive gear 324 is rotatably fitted on the shaft 335, and the transmission gear 336 is attached to the other end of the shaft 335. The ring-shaped receiver fitted in is prevented from being removed by a member 337.

The support body 309 also has both sides 310.31.
A support portion 338 is bent approximately in the center between the two sides and is arranged parallel to the side surfaces 310° and 311. This support part 338
One end of a shaft 339 is fixed to the. This shaft 339 has first and second gear parts 34 having different diameters.
A substantially cylindrical operating gear 3 integrally formed with 0°341
42 is loosely fitted in a rotatable manner. Here, the first gear portion 340 of this operating gear 342 is connected to the transmission gear 336.
It is geared to the

Furthermore, one end of a loading lever 343 is rotatably fitted into the tip of the shaft 339. This loading lever 343 is prevented from being removed by a washer 344 fixed to the tip of l1il11339. A ring-shaped friction member 345 made of, for example, felt is interposed between the loading lever 343 and the operating gear 342. Further, a ring-shaped spring bearing plate 346 is provided on the left end surface of the operating gear 342 in FIG. 347
is interposed between the operating gear 342 and the loading brake. -343 are biased so as to be pressed against each other via a friction member 345.

At the other end of the loading lever 343,
A rotating shaft 348 is loosely fitted so as to be rotatable. A loading gear 350 that meshes with the second gear portion 341 of the operating gear 342 via a washer 349 is fitted onto one end of the rotating shaft 348 . In addition, the rotating shaft 3
A loading pulley 352 is fitted onto the other end of 48 with a washer 351 interposed therebetween.

A flange 3 that can sandwich the peripheral edge of the disk 101 in the thickness direction is provided on the peripheral side of the loading pulley 352.
53 is formed. A ring-shaped friction material 354 made of, for example, rubber is fitted between the flanges 353.

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 disc autochanger device shown in FIG. Since the side surfaces 310, 311, etc. overlap each other, they are shown with one leader line and two numbers each in the drawing.

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. And the guide rails 303, 304
When the loading unit 307 is in the non-driving position, the loading lever 343 (D 20th
A locking portion 355 having an abbreviated side shape is formed to engage with the lower end portion in the figure and hold the loader lever 343 from falling downward in FIG. 21 about the shaft 339. ing. For this reason, the loading unit 30
7 is in the non-driving position, the tray portion 100i
Disk 101 that is stored and whose center position is DC, a point
Needless to say, the disk selection mechanism section 200 pushes up from the tray section 100 and the center position is DC,
The loading pulley 352 is also configured not to come into contact with the disc 10) which is set as a point.

Further, when the loading pulley (J07) 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, for example. This leaf switch 356 is
This is for detecting the position of the rope ink unit 307, and when this leaf switch 356 is in the on state (the state in which the loading unit 307 is in the non-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 that drives the.

In this way, when the disk 101 is pushed up from the tray part 307 with the loading unit 3077% in the non-driving position, the motor 30B of the loading unit 307 is rotationally driven by the sequence control of the control circuit 910. Ru. The rotation direction of this motor 307 is controlled so as to rotate the moving gears 319, 320 clockwise in FIG. 21. For this reason, the loading unit 307
3, 304 in the direction of arrow L1 in FIG.

Then, the loading lever 343 is separated from the locks 5355 formed on the guide rails 303 and 304. Here, the rotational force of the motor 30B is transmitted via the worm gear 327, drive gear 324, transmission gear 336, and operating gear 342 to the loading lever 343 via the friction member 345, and is transmitted to the loading gear 343 via the friction member 345. 350 and the rotation shaft 348 to the loading pulley 352 .

The rotation direction of the motor 308 is determined by the moving gear 31.
9, 320 in the clockwise direction in FIG. 21, the transmission gear 336 is rotated counterclockwise in FIG. 21, and the operating gear 342 is rotated in the clockwise direction in the figure. .

Therefore, the friction member 3 is attached to the loading lever 343.
45 to the loading pulley 352 to the disk 10
A rotation biasing force is applied in the direction of contacting 1. In addition, the loading pulley 352 itself has a 21st
Rotational force in the counterclockwise direction in the figure is transmitted.

Therefore, when the loading unit 3o7 is moved in the direction of the arrow L1 in FIG. 21 and the rope ear f lever 343 is separated from the locking portion 355, the loading sled 352 rotating counterclockwise in FIG.
It is brought into pressure contact with the disk 101 which has been pushed up from J and is at the center position DC2. In this case, the peripheral edge of the disc 101 is interposed between the flange 353 of the loading pulley 352, and the peripheral side of the disc 101 is pressed against the friction material 354.

Therefore, as shown in FIG. 18(b), the disk 101 pushed up from the tray section 100 is again rotated in the direction of escape from the tray section 100 by the rotational force of the loading pulley 352. Since the disk 101 is moved along the I-id rails 303 and 304 to push out the disk 101, the disk 101 ends up rolling along the loading path 3.
01.

Here, as shown in FIG. 21, the guide rail 303,
At the right end of 304 in the figure, there is a loading unit 307.
guide portion 323 (the guide portion of the side surface 311 is not shown)
A stop Z4 portion 357 is formed which abuts against and forcibly stops the movement of the loading unit 307 in the direction of the arrow L1. For this reason, loading unit 307
The movement in the direction of arrow L1 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 DC in FIG. 18(b).

Note that even if the loading unit 307 is stopped, the rotation of the motor 30B is not stopped. That is, when the loading unit 307 is in a stopped state, as shown in FIG. It is something that The rotational force of the drive tooth section 324 is used for the 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 loading pulley 35
2 is brought into pressure contact with the outer periphery of the disk 101, so by simply pushing up the disk 101 to be selected by about 5 mm from the tray section 100, it can be reliably distinguished from the other disks 10 and taken out. This prevents the wrong disk 101 from being ejected, and is also suitable for downsizing. Also, disk 10
Since the disc 1 is taken out from the tray part ioo through the roller 2, the disc 101 can also be taken out easily and smoothly.

Furthermore, since the outer periphery of the disk 101 is sandwiched between the flange 353 of the loading pulley 352,
The disk 101 can be stably transferred, and the disk 101 can also be positioned when it is guided into the loading path 301, which can further contribute to smooth loading operations.

Further, the rotational force of the drive gear 324 is applied to the friction plate 32 through a friction mechanism such as a friction member 328 and a stripe ring 332.
9 and, in turn, to the moving gears 319, 320, the rotational force of the moving gears 319, 320, the rotational force of the moving gears 319, 320,
The force moving on 3° 304 is not stronger than the frictional force of the friction mechanism. This means that the force with which the loading pulley 352 pushes out the disk 101 while rotating is regulated to a certain value without correcting the +Hy condition. Therefore, the disk 101 can be transferred safely.

Note that since the operating gear 342 and the loading gear 343 are connected via a friction mechanism consisting of a friction member 345 and a spring 347, the force with which the loading gear 352 is pressed against the disk 101 is limited to a certain value. In this respect as well, disc 10
It is designed so that no excessive force is applied to 1.

Furthermore, as is clear from FIG. 20, the drive gear 324
The diameter of the transmission wheel 336 is made smaller than the diameter of the second gear portion 326.

Therefore, the rotational speed of the transmission gear 336 is the same as that of the drive gear 32.
The rotational speed of 4 is also faster, which means that the speed has been increased. The diameter of both transmission parts 336 and the operating gear 34 are
The diameter of the second gear part 341 of the operating vehicle 342 and the diameter of the loading gear 350 are substantially the same. Therefore, the rotational speed of the loading spool 352 is equal to the rotational speed of the drive gear 324, the rotational speed of the pawl moving gear, and ? J9, J2
This means that the rotation speed is faster than the zero rotation speed, that is, the speed is increased.

On the other hand, the diameter of the loading spool 352 is the same as that of the moving gear 31.
Since the diameter of 9,320 is also large, the speed of the peripheral portion of the loading spool 352 and the circumferential speed of the spool are lower than those of the moving gear 31.
The circumferential speed of 9,320 mm is also increased.

Therefore, after the disk 10 is rotated by the rotational force of the loading pulley 352 itself, the loading unit 907 is moved to follow the disk 101. Therefore, the loading unit 307 is faster than the disk 101, and there is no possibility that the loading unit 307 will move over the disk 101.
This allows the disk 101 to be brought into contact with the disk 101 in such a manner as to push out the disk 101, thereby allowing stable transfer of the disk 101.

Next, the second loading mechanism section 400 will be explained. That is, as shown in FIG. 21 again, the loading unit 307 reaches the right end of the guide rails 303, 304 in the figure, and the loading unit 307 reaches the stop I? 357 and is stopped, the second gear part 32 of the drive gear 324
6 is now meshed with the cam gear 401.

As shown in FIG. 22, this 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. A washer 40 attached to the tip of the shaft 403
4 prevents removal.

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. 21, a part of the flat part 406 has
A substantially doglegged notch 407 is formed. Then, the second gear portion 32 of the drive gear 324 is attached to the cam gear 401.
6 are not engaged, a retaining portion 409 protruding from one end of the holding member 40B is located at the innermost part of the cutout portion 407.

This holding member 40B 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 40B.

This is the unloading path 101 for the pocket section 5/3 and the disk 10/disk section unloading path 802.
When sending out the disc 10 to the guide part 515
Since the rotation of the disk 101 is sent out in a circular motion, it is possible to control the operation of the disk 101 as reliably as possible.

The guide portion 5-5 provided in the opening 5-4 of the pocket portion 5-3 is shaped like a step so that the disk 101 rolls under its own weight, and the loading path 30 and the unloading path 30 are shaped like steps. It is also effective to construct the disc 10 so that it can be taken in and out in a state corresponding to the loading path 70, the external disk loading path 801, and the external disk unloading path 802, respectively.

The fifth point is that the heating material soe for carrying in and out of the disk from the outside is configured as a receiving part for carrying in and out of the disk to the outside of the tray part 100 for supplying the internal disk.

In other words, this serves as a disk holder when loading and unloading 10 external disks, and can contribute to improving the handling of disks from the outside as much as possible. It is what it is.

Next, as above, the disk pocket & structure SO
A disk temporary standby mechanism section 600 temporarily waits the disk 101 transferred from O in the unloading path 701, and a tray section Lo.

The unloading mechanism section 700 that returns to the original state will be explained. That is, as shown in FIG. 29, the disk 101 that has finished playing and has been transferred from the disk pocket mechanism section SOO into the unloading path 70 is still in contact with the substantially round-shaped locking section 601. It is placed in a standby state within the unloading path 701.

Here, the locking section 601 is connected to an unloading mechanism section 700. That is, in FIG. 29, a frame 704 is fixed to the upper plate 14 (not shown in FIG. 29). In this frame 7θ4,
A motor 206 is attached via a handle 705,
The rotating shaft 207 of the motor 706 has a worm gear 2
08 is fitted. And this worm gear 20
8 is meshed with a drive gear 709 rotatably supported by the frame 704.

Further, the driving gear 7θ9 is meshed with two horns of the friction gear of the unloading unit 2JO. 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. Opposing both sides 713 and 714 of this unloading member 7J2 extend in the same direction, and one side 2
The distal end in the extending direction of 14 is formed into a substantially disk shape, and the friction portion 7
15.

Friction part 7 of this unloading member 2)
A shaft 717 is loosely inserted from the outside of the friction portion 715 into the through hole 7 6 formed in the center of the friction portion 715 . This axis 717 is
Friction member 71 formed in a ring shape, for example, from felt or the like
8. Through hole 71 formed in the center of the friction gear 71
9-ring-shaped friction part 72o, a through hole 722 formed at one end of the operating lever '121, and a coil-shaped spring 723 are loosely inserted into the unloading member 7.
It is loosely inserted into a through hole 724 formed on the side surface 713 of No. 2, and an E IJ ring 725 is fitted to the tip thereof to prevent it from being removed.

Here, among the shafts 712, the unloading member 7
The outwardly projecting portions of the 12 friction parts 7 and 5 are fixed to the frame 204. Therefore, the unloading member 112 is attached to the shaft 21 with respect to the frame 704.
It is supported so as to be rotatable around 7. Further, the friction gear 711 is rotatable about a shaft 717, and the operating lever 72 is rotatable about a shaft 717.

Furthermore, the friction portion 71 of the unloading member 712
5. Friction members 718, 720. The friction gear 71 and the operating lever 72 are pressed against each other by a spring 723. The locking portion 60 is attached to the other end of the operating lever 72. Note that even when the unloading member 712 is rotated about the shaft 717, the driving gear 709 and the friction gear 71 are of course in mesh with each other.

Also, one side surface 7 of the unloading section side 712
13, a shaft 727 is loosely inserted into a through hole 726 formed in the center of the side Tl1i 713. This shaft 727 is connected to the through hole 2 formed in the center of the transmission gear 728.
29 is loosely inserted into the through hole 7 formed on the other side surface 714.
,? 0 is loosely inserted. Of this shaft 727, both sides 213°2 of the unloading member 712
The part projecting outward from 14 has an E-ring 781.7.
32 are fitted into each other to prevent them from coming off. Thus, 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 meshes with the friction gear 7. This is what is being done.

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 7-3. This axis 736
Of these, the portion that protrudes outward from the side surface 713 is
An unloading gear 738 is loosely inserted into the shaft 736, a through hole 739 formed on the other side surface 714 is loosely inserted, and an E ring 740 is attached to the tip of the shaft 736. The unloading gear 73 is fitted and prevented from being removed.
8 is fixed to the shaft 736 by screw 24, and the shaft 7
36 to rotate integrally with it. and,
This unloading gear 738 is connected to the transmission gear 72.
It is meshed with the second gear portion 734 of No. 8.

Here, as shown in FIG. 29 again, the mounting plate 402
A shaft 742 is installed at a predetermined position, and the shaft 74
2, one end of a detection lever 743 is rotatably supported. A cam portion 745 that can be engaged with and disengaged from a microswitch 744 attached to the frame 704 is formed at the rotating base end of the detection lever 743 . Note that this microswitch 744 is for detecting that the disc is placed in the tray section 1θ0, and the details will be described later. Further, a detection pin 746 is installed at the other end of the detection lever 243 so as to be substantially parallel to the locking portion 601.

The operation of the unloading mechanism section 100 configured as described above will be described below. First, when the reproduced disk 10 is transferred into the disk decking machine's unloading path 70 (as described above), the nuclear disk 10 hits the locking section 60 and is stopped. It is put into 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 SOO for reproduction. During this reproduction, the control circuit 91
0 sequence control, the motor 706 is rotationally driven.

The rotational force of the motor 706 is transmitted to the friction gear 71 via the drive gear 709. At this time, the motor 70
The direction of rotation of the friction gear 711 is indicated by the arrow in FIG. 29:
It is controlled to rotate in the direction. The rotational force of the friction gear 7 in the direction of arrow L2 is then applied to the friction member 7.
1B to the unloading member 712, and the operating lever 721 via the friction part y2o.
transmitted to. For this reason, the unloading member 712
At this time, a rotating force g1/+ is applied in the direction of bringing the unloading roller 731 into contact with the peripheral 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 72 in a direction to move the locking portion 60 away from the disk 101, that is, in the four directions indicated by arrows in FIG. Therefore, the disk 101 is released from the locking portion 60 and becomes movable in the direction of the tray portion 100.

On the other hand, the rotational force of the friction member 71 in the direction of arrow L2 is
Transmission gear 728, unloading gear 738 and shaft 7
36 to the unloading roller 737. 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 toward the tray portion 10θ, that is, in the direction indicated by the arrow in FIG. 29.

Therefore, the unloading roller 737 rotated in the direction of the arrow L5 is moved in the direction of the force of the arrow Ls and is brought into pressure contact with the circumferential side of the disk 1010 in the standby position, so that the disk 101 begins to roll out in the direction of the tray section 100. .

Then, the unloading roller 737 is moved in the direction of arrow L3 so as to further push out the rolled disk 10, so that as shown in FIG.
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 disk 101
01 presses the detection bin 746, the detection lever 743 is rotated in substantially the same direction as the operating lever 721, in the direction of arrow L4 in FIG.

Here, when the detection lever 743 is in the position shown in FIG. 29, the microswitch 744 is turned on by the action of the cam portion 745.
When the disk 101 is moved in the direction of the tray section 100 and the center position of the disk 101 reaches the DC3 point as shown in FIG. 18(b) again, the detection lever 743 is rotated most clockwise in the figure. state.

At this time, the four parts 747 formed on the cam part 745 face the microswitch 744, so the microswitch 744 is turned off.

Then, when the disc 101 is completely stored in the tray section 100, the detection lever 243 moves to the 29th position due to its own weight without the detection lever 243 touching the disc 10.
It is returned to the position shown in the figure. Then, the cam portion 74
5, the microswitch 744 is turned on.

When the microswitch 744 is switched from the OFF state to the ON state, the control circuit 910 detects that the disk 10 is completely accommodated in the tray portion 1θO, and reverses the motor 7θ6. control so that Therefore, the unloading section old 712 and the operating lever 72 are returned to the positions shown in FIG. 29, so that they can handle the next unloading operation.

Therefore, according to the disk temporary standby mechanism section 600 and the unloading mechanism section 700 configured as described above,
First, since the disk 101 that has finished playing is temporarily held in the unloading path 701, the next 10 disks are played during this waiting period, and the disk lθ is returned to the tray section 100 during this playback. This makes it possible to shorten the re-stopping and interruption time as much as possible, and to quickly replace the disks 10. In this case, the disc autochanger device described here causes the disc 101 to take different paths during loading and unloading.
A similar effect can be obtained by providing a special unit that temporarily waits for disc 101 and loading the next disc 10 through the above path while the special unit is waiting for disc 101. Of course.

Further, according to the above-mentioned disk temporary standby mechanism, the movement of the disk 101 is prevented by the locking portion 601, so the configuration is extremely simple, and the disk 101 is prevented from moving.
There is no need for excessive force to be applied to the part.

On the other hand, according to the unloading mechanism section 7oo, the rotating unloading roller 7.97 is connected to the disk 10.
1 is brought into contact with the disk J (I7), and the tray section J (as it is pushed into the JO, the other disks 10 stored in the tray section LμJ) are reliably pushed out without any influence on the other disks 10 stored in the tray section LμJ. Tray part 1 on disc 10
It can be stored in 00.

Further, since the disc 101 is stored in the tray portion 100 while shifting, the disc 101 can also be stored smoothly and easily.

Further, since the detection lever 743 is moved while engaging with the first white contact disk 101, the first white contact disk 101 is moved.
00 can be detected reliably and accurately.

It goes without saying that the present 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 the invention.

〔Effect of the invention〕

Therefore, as described in detail above, according to the present invention, it is possible to contribute to an improvement in the disk exchange speed, and to satisfy the requirements of ensuring operation with a simple configuration. It becomes possible to provide an extremely good disc autochanger device.
