FIG. 29 is a view showing the relationship (the tray is not shown), and FIG. 29 is a view showing a state in which the disc playing unit is raised in the unit chassis and the disc is held on the turntable.

26, 27, 28, and 29, the intermediate chassis 265 is a member that supports the disc playing unit 202 via a damper (not shown). The gear C254 meshes with the rack 262 of the slider L261, moves the slider L261, and raises the intermediate chassis 265 on which the disc playing unit 202 including the optical pickup 203 is mounted.

In the sliders L261 and R263, the recesses 284 at the ends are fitted with the projections 285 at both ends of the connecting arm 264, and the centers thereof are simultaneously moved through the connecting arms 264 rotatably supported. Slide in the opposite direction.
At that time, the connecting arm 264 rotates in the direction of arrow K. The inclined grooves 266 on the side surfaces of the slider L261 and the slider R263 are
The convex pins 267 of the intermediate chassis 265 are fitted in two places and one place, respectively. The slider L261 and the slider R263 slide on the intermediate chassis 265, so that the intermediate chassis 265 rises along the inclined surface of the inclined groove 266.

When the turntable 204 on the disc playing unit 202 mounted on the intermediate chassis 265 moves upward in the direction of arrow B to above the disc mounting surface 106 of the tray 104, the disc 1 on the tray 104 is placed on the turntable 204. Placed on. The clamper 210 facing the turntable 204 magnetically attracts the turntable 204 and holds the disc between the turntable 204 and the clamper 210.

Thereafter, the detection switch 268 is moved to the slider L261.
Is pushed via the lever 269, and the control unit (not shown) stops the drive motor 252 and the gear A250. In this state, the disc playing unit 202 drives the turntable 204 by its spindle motor 205 to rotate the disc 1,
The optical pickup 203 reads the signal of the disc 1.

Next, FIG. 30 is a diagram showing the on / off relationship between the detection portion of the detection member and the switch.

As shown in FIG. 30, a detecting member 307 having a detecting portion 307a corresponding to the position corresponding to each of the trays 104 accommodated in the stocker 100 and the home position of the disc carrying / playing unit 200, The sensor 306 is arranged on the same side as the main slide guide 207 (see FIGS. 7 and 8).

Next, the disc carrying means will be described.
The disc transport means is the disc transport / performance unit 200
Is a mechanism that moves the guide shafts 208 and 209 in the directions of arrows A and B, and includes gears, pulleys, and the like that transmit the driving force from the unit transport driving unit 309 (see FIGS. 1, 2, and 3).

When performing playing and loading / unloading of the disc 1, the disc carrying / playing unit 200 is at the position of the lowermost loading tray 2, that is, the home position where the inner tray 4 in the loading tray 2 can be pulled out onto the disc playing unit 202. To the position of the tray 104 on which the disc 1 is instructed by the control unit. At this time, the switch 308 for detecting the home position of the disc carrying / playing unit 200 is changed from on to off (see FIG. 30). The loading tray 2 and the stocker 10 are at the lowest position when the disc transport / performance unit 200 moves in the substantially vertical direction.
A home position detection switch 308 is arranged between 0.

Then, the disc transport / performance unit 200
The sensor 306 attached to the main slide guide 207 side detects the detecting portion 307a of the detecting member 307, and detects the substantially vertical position corresponding to each of the trays 104 stored in the stocker 100 (see FIG. 7). . This makes the target tray
Move to position 104. Further, the mounting vertical position of the loading tray 2 is set to an integral multiple of the storage pitch of the tray 104 in consideration of the detection unit 307a detected by the sensor 306.

Further, the driving force of the unit transport driving unit 309 is transmitted through the gears 218 and 290 of the connecting gear 310 and then to the pulley gears 219 and 22.
The timing belts 222 and 223, which are movably supported by 1 and pulleys 224 and 225, are attached to the disc transport / performance unit 20.
Connected to each of the main slide guide 207 attached to one end of 0 and the sub slide guide 206 attached to the other end, the disc carrying / playing unit 200 is moved in the directions of arrows A and B (see FIG. 13).

The driving force of this unit transport driving unit 309 is
Since it is transmitted by the transport drive meshing portion 218b of the worm gear 216 and the coupling gear 310, the unit transport drive portion 309 can be attached last. Further, the connecting gear 310 is attached to the lower portion of the loading tray 2 to reduce the size of the apparatus.

The pulley gears 219 and 221 that movably support the timing belts 222 and 223 are composed of gear portions 219a and 221a and pulley portions 219b and 221b, respectively. Even if it is set to a small value, the disc transport / performance unit 200 can be accurately driven in a short time.
Further, the connecting gear 310 meshes with the unit transport drive section 309 by the transport drive meshing section 218b, and the pulley gears 218a, 290a of the gear 290 via the gear 218 and the synchronous shaft 220 form the pulley gear 2.
The gear parts 219a and 221a of 19 and 221 are meshed with and driven.

Further, since the disc holding means holds the disc 1, the clamper support plate 211 for supporting the clamper 210 is provided.
Are attached in such a manner that the main slide guide 207 and the sub slide guide 206 are connected to each other. As a result, the number of parts can be reduced without the need for new attachment parts.

Next, a positioning portion is provided on the unit chassis 201 of the disc transporting / playing unit 200, and the sub-slide guide 206 and the main slide guide 207 are substantially positioned.
By moving the disk transport / performance unit
The 200 can be easily mounted in the correct position (Fig. 12
reference).

Further, the slave slide guide 206 shown in FIG.
The main slide guide 207 has the same height surfaces 206a and 207a that have the same height when attached to the unit chassis 201, and are movably fitted to the guide shafts 208 and 209 (see FIG. 1), respectively. ing. This makes it easy to attach the same to the timing belts 222 and 223 that move in the substantially vertical direction of the disc transporting / playing unit 200 by aligning the same height surfaces 206a and 207a.

Next, the operation of the tray transfer means will be described. First, the operation of engaging and separating the hook 234 and the tray 104 will be described with reference to FIG.
When moving in the direction of the stocker 100 (arrow E direction) along the line 36, the protrusion 24 on the unit chassis 201 near the stocker 100
Touch 8. While the hook 234 is in contact with the protrusion 248 and further moves in the stocker 100 direction (direction of arrow E), the hook 234 rotates on the hook support slider 235 as indicated by arrow G. While the hook 234 rotates, the hook supporting slider 235 moves to engage and disengage from the tray 104. The initial position of the operation is the position where the hook 234 is closest to the stocker 100 side (the position of the hook 234 shown by the arrow H).
At this position, the hook 234 contacts the protrusion 248 and rotates, and is separated from the tray 104. This initial position (Fig. 7
2), the disc transport / play unit 200 smoothly moves relative to the stocker 100 in the directions of arrows A and B (see FIG. 2).
(See) can be moved to.

From the initial position, the hook 234 conveys the disc /
When moving in the direction of the playing unit 200 (direction of arrow F), the hook 234 rotates clockwise (direction opposite to arrow G) in the drawing. The hook 234 is spring 272 on the hook support slider 235.
Is urged clockwise by. As it rotates, the hook 234 has its tip inserted into the hook engaging portion 109 of the tray 104 and engages with the tray 104. Tray 104 engaged
Following the movement of the hook 234, is pulled out onto the disc transport / play unit 200. At this time, the hook 234 is
This is the position indicated by arrow J in (a).

On the contrary, when returning the tray 104 to the stocker 100,
By moving the hook 234 toward the stocker 100, the hook 23
The tip of 4 pushes a part of the hook engaging portion 109 of the tray 104,
Return the tray 104 to the stocker 100. Unit chassis 201
From the position where the hook 234 contacts the projection 248 of the
4 moves while rotating as shown by arrow G. The tray 104 is pushed down along the movement path of the tip of the hook 234, and the hook 234 separates from the tray 104. Further, the position where the tray 104 is pushed down is the position where the tray 104 is stored in the stocker 100.

Further, the hook supporting slider 235 is linearly moved along the guide shaft 236 in order to engage the hook 234 and the tray 104 and to move the tray 104, to return the tray 104 to the stocker 100, and to move the tray 104 away. It can be done smoothly with a series of operations. Further, the operation of engaging and separating the tray 104 and the hook 234, and the operation of the subsequent movement only need to switch the moving directions of the hook 234 and the hook support slider 235, which is a very simple mechanism.

When the tray 104 is returned to the stocker 100,
The hook 234 comes into contact with the protrusion 248 and rotates to hook 234.
Since the tray 104 is pushed completely by the hook 234 due to the trail of the tip, the tray storage position in the stocker 100 is almost the protrusion 2.
It depends on the position of 48. The protrusion 248 is the unit chassis 2
Since it is integrated with 01 (see FIG. 12), its position can be easily determined and an accurate tray storage position can be obtained.

Next, as a means for moving the tray 104, the hook supporting slider 235 is fixed to the timing belt 239 to move the hook supporting slider 235 shown in FIG. The timing belt 239 is driven by being supported by the second pulley 243 and being connected to the driving means via the first pulley 241. Then, the hook 234 pivots on the hook support slider 235, thereby making it possible to take a position engaged with the tray 104 and a position separated from the tray 104. At this time, the hook
At the position where 234 is separated from the tray 104, the hook 234 is at the second position.
The position is set to be substantially above the pulley 243 (see FIG. 7).

By the way, the tray 104 needs a space for avoiding the hook 234 and a space for avoiding the second pulley 243, but since the position where the hook 234 is separated from the tray 104 is above the second pulley 243, The notch 276 (see FIGS. 16 and 18), which is a space for avoiding the second pulley 243, can avoid both the second pulley 243 and the hook 234. In addition, a guide shaft 236 for guiding the hook support slider 235 so as to be linearly movable is installed substantially above the first and second pulleys 241, 243.

Further, a shaft 242 is installed in a substantially vertical direction to rotatably support the first pulley 241, and a shaft 244 is installed in a substantially vertical direction to rotatably support the second pulley 243. 2 A guide shaft supporting hole 246 that is orthogonal to the axial direction is provided above the pulley supporting portion of the shaft 244 that supports the pulley 243, and the guide shaft 2 that guides the hook supporting slider 235 so as to be linearly movable 2
36 was fitted in the guide shaft support hole 246 and installed.

Next, a drive motor 252 shown in FIG. 21 is provided as a drive means for moving the tray 104 on which the disc 1 is placed from the stocker 100 storing the disc 104 to the disc playing unit 202.
And a gear A250 driven by the drive motor 252,
The gear A250 and the gear B253 connected to and driven by the tray transfer means for moving the tray 104, and the gear D255 (gear A250 to gear D255 to gear B253) installed between the gear A250 and the gear B253.
~ Gear A250 by drive transfer called tray transfer means ~
Gear B 253 to tray transfer means (which can drive the tray transfer means in the opposite direction to the drive transmission) (see FIGS. 24 and 25), and gear A 250 has gear b 257, which is provided only in a certain angular range on the outer periphery thereof. It has a gear c258 and a gear d259 (Fig. 22, Fig.
23).

Besides the gears B253 and D255, the gear C254 for driving the disc holding means is driven. Further, the positional relationship among the gear b257, the gear c258, and the gear d259 on the gear A250 is such that when the gear A250 is rotationally driven in one direction by the drive motor 252, the gear b257 drives the gear B253 and then the gear c258 drives the disc holding means. The gear C254 for driving the gear is driven, and then the gear D255 is driven by the gear d259. Thus, one drive motor 252 pulls out and stores the tray 104, and holds and releases the disc 1 on the turntable 204 by moving the disc playing unit 202 having the optical pickup 203 in the directions of arrows A and B. It can be carried out.

Further, when the gear A250 is rotated in one direction, the tray 104 is pulled out and the disc 1 is rotated by the turntable 204.
Between the clamper 210 and the clamper 210, and the stocker 10 of the empty tray 104
Return to 0 can be done by a series of operations, and then gear A250
It is possible to pull out the empty tray 104, place the disc 1 on the tray 104, and return the disc 1 and the tray 104 to the stocker 100 by a series of operations by rotating the disc 1 in the stocker Can carry in and out of 100. Further, in the operation of this driving means, the stocker 10
Detection switch 27 that detects the end of the disk return operation to 0
4. It can be constructed by using only two detection switches 268 for detecting the end of holding the disc after pulling out the tray 104 during playing.

Further, a tray stopper 105 for holding the tray 104 is provided in the stocker 100 for accommodating the tray 104 on which the disk 1 is placed, and the stocker 1 is moved by the tray transfer means.
Set the indicated tray 104 in 00 to the disc playing unit 202
When moving to the position of, a groove cam 251 mounted on the unit chassis 201 and provided on the plane portion of the gear A250 is provided as means for opening the tray stopper 105 corresponding to the tray 104 and making the tray 104 movable. A tray stopper opening / closing arm 249, which is a member that is driven and acts on the tray stopper 105 to move the tray 104 in the opening direction, is provided.

By providing the grooved cam 251 to be driven on the plane portion of the gear A250 which is a gear for determining the operation timing, the operation timing can be accurately made and the tray stopper 105 can be opened immediately before the start of the tray pull-out operation. Similarly, the tray stopper 1 is operated by a series of operations by rotating the gear A250.
Since 05 can be opened, the detection switch 274 described above can also be used as the detection switch for the end of operation.

Further, on the tray stopper opening / closing arm 249,
A guide wall 287 for moving the tray when the tray 104 is moved is provided (see FIGS. 16, 17, 18, 19, and 20). This enables a smooth movement of the tray movement.

Next, the tray stoppers 105 for holding the trays 104 in the stocker 100 are configured to simultaneously hold a plurality of trays 104. At this time, before moving the designated tray 104 in the stocker 100 to the position of the disc playing unit 202 by the tray transfer means between the stocker 100 and the disc playing unit 202, the tray stopper 105 corresponding to the tray 104 is opened. Then, the movable tray stopper opening / closing arm 249 is provided with two vertical walls 260 for preventing the tray 104 above and below the tray 104, which is moved when the tray stopper 105 is opened, from being released from the stocker 100. I set up some places.

As a result, the tray stopper 105 is attached to the tray 1.
It is possible to use one for each without having to provide each of 04. Further, by being integrated with the tray stopper opening / closing arm 249, the tray stopper opening / closing arm 249 is used to sufficiently separate from the tray 104 when the disc carrying / playing unit 200 is moved (see FIGS. 16 and 17). 1
When the tray 04 is pulled out, it can come close to the tip of the tray 104 that is not pulled out (see FIGS. 18 and 19).

Next, each drive operation will be described in order. Stocker
When playing a disc stored in 100, the disc transport / play unit 200 includes a unit transport drive unit from the position of the loading tray 2 at the lowermost stage to the position of the tray 104 on which the disc 1 is instructed by the control unit. Driven by 309 and rises. Up to the target tray 104 Detection unit of detection member 307
The sensor 306 detects 307a and stops. At this time, the tray 104 on which the target disk 1 is placed is held by the tray stopper 105 in the stocker 100. At this time, in the disc carrying / playing unit 200, the hook 234 is at a position separated from the tray 104 (the position of the hook 234 shown by the arrow H in FIG. 14A). The gear A250 has an arrow M shown in FIGS. 16 and 21 (a).
When the tray stopper opening / closing arm 249 is rotated in the direction, the tray stopper opening / closing arm 249 is driven by the groove cam 251 of the gear A250 to rotate, and the stocker 100 is rotated.
Open the tray stopper 105 (see FIGS. 18 and 19).

Since the tray stopper 105 holds the plurality of trays 104, the plurality of trays 104 are opened, but the vertical wall 260 at the tip of the tray stopper opening / closing arm 249 is positioned at the tip of the tray 104 other than the target at this time. However, the unnecessary tray 104 is prevented from popping out while the apparatus is operating (states of FIGS. 18 and 19).

Next, the gear A250 shown in FIG. 21, FIG. 22 and FIG.
Gear b257 meshes with gear B253. Gear B253 is first
The timing belt 239 connected to the gear 245 of the pulley 241 and connected to the hook support slider 235 is driven to convey the tray 104 from the stocker 100 to the turntable 204 (state in FIG. 8). Also, the hook 234 at this time
The path of the driving force for driving the is shown by the thick dashed line in FIG.
Around the time when the gear B253 is disengaged, the gear c258 of the gear A250 then meshes with the gear C254 to drive the disc playing unit 202 up and down (see FIGS. 26 and 27). The main slide guide 207 and the slave slide guide 206 are held between the clamper 210 provided on the clamper support plate 211 and the turntable 204 so as to be played (see FIG. 29).

After the performance, the drive motor 252 rotates in the reverse direction,
Gear A250 rotates in the direction of arrow N, which is the reverse of the previous one. The disc playing unit 202 descends in the direction of arrow A in the reverse operation to the above action, and the disc 1 is turned on.
Move from top 204 to top tray 104. After that, the gear C254
The meshing is disengaged, the gear b257 of the gear A250 is again meshed with the gear B253, and the hook 234 is driven. After the tray 104 on which the disc 1 is placed is returned to the stocker 100, the gear B253 is disengaged. Around this time, the tray stopper opening / closing arm 249 starts to rotate by the groove cam 251 of the gear A250, and the tray stopper 105 engages with the tray 104.
After that, as shown in FIG. 16, the detection switch 274 is operated by pushing the tray stopper opening / closing arm 249, and the control unit (not shown) stops the drive motor 252 and the gear A250.

The same applies to the case of playing the disc 1 on the loading tray 2. The disc carrying / playing unit 200 descends to the home position and the switch 308 is turned on. The inner tray 4 on which the disc 1 in the loading tray 2 is placed is pulled up to above the disc playing unit 202 to perform as described above. At this time, the loading tray 2 is opened by the tray stopper opening / closing arm 249.
Open and close the inner tray stopper 5 of.

Next, the operation of loading the disc 1 into the stocker 100 from the loading tray 2 will be described. The same operation is performed until the disk 1 placed on the inner tray 4 is held on the turntable 204. After that, the gear A250 continues to rotate in the direction of the arrow M, and the gear c258 is disengaged. Next, gear d259 of gear A250 is gear D
Mesh with 255. The gear D255 always meshes with the gear B253 and drives the hook 234 via the gear B253. Since the gear B253 is driven via the gear D255, the gear B253 drives the hook 234 in the stocker 100 direction (arrow E direction) even though the gear A250 rotates in the arrow M direction.

The path of the driving force for driving the hook 234 at this time is shown by a thick chain line in FIG. Gear B253 is gear D2
Since it is driven by 55, it rotates in the direction opposite to the rotation direction when meshed with the gear b257. The inner tray 4 is returned to the loading tray 2 while the disc 1 is placed on the turntable 204 by the movement of the hook 234. After that, as the gear A250 rotates, the gear D255 disengages from the gear d259, and the tray stopper opening / closing arm 249 is driven by the groove cam 251 around that time to close the inner tray stopper 5. The tray switch opening / closing arm 249 operates the detection switch 274, and the drive motor 252 and the gear A250 are stopped.

The disc carrying / playing unit 200 holding the disc 1 between the turntable 204 and the clamper 210 is
It moves to the tray 104 position of the designated stocker 100.
The tray 104 at this position is in an empty state in which the disc 1 is not placed. At that position, the gear A250 starts rotating in the direction of arrow N.

The tray stopper opening / closing arm 249 is driven to open the tray stopper 105 of the stocker 100. Sequentially, the gear d259 of the gear A250 meshes with the gear D255, the hook 234 is driven toward the turntable 204, and the empty tray is driven.
104 is withdrawn. When the gear D255 disengages from the mesh of the gear d259, the gear c258 of the gear A250 then shifts to the gear C254.
Start meshing with. Gear C254 drives rack 262,
The slider L261 and the slider R263 slide, and the disc playing unit 202 moves in the direction of arrow A. After that, the disc 1 is placed on the tray 104, and the tray 104 on which the disc 1 is placed is the stocker 100, as in the operation at the end of the performance.
Is stored in.

The operation of unloading the disc 1 from the stocker 100 to the loading tray 2 is the same as the above-described operation. First, the stocker 100 is accessed to access the disc 1
Is taken out and conveyed to the position of the loading tray 2.
The same can be done when moving the stored disks 1 to the trays 104 at different positions in the stocker 100.

The operation of the disc playing device of this embodiment having the above-described structure will be described below.

First, the operation of playing the disc 1 stored in the stocker 100 will be described. Stocker 100
When the desired disc 1 is selected from the 50 discs 1 accommodated therein, the disc transport / playing unit 200 causes the unit transport drive unit 309 to store the desired disc 1 from the home position. Target tray 10
The position of 4 is detected by the sensor 306 of the detection unit 307a of the detection member 307 and moved to that position. When the operation is completed, the tray stopper 105 is opened by the tray transfer means, and the tray 104 on which the desired disk 1 is placed is moved onto the disk playing means 202. Then, the disc holding unit moves up the disc playing unit 202 to hold the desired disc 1 between the turntable 204 and the clamper 210 (see FIG. 29). In this state, the spindle motor 205 rotates and the optical pickup 203 reads the signal of the disk 1 to perform the performance.

When the performance ends, the disk 1 is stored in the stocker 100 at the original position by the process reverse to the start of the performance. When the disc 1 is completely stored in the stocker 100, the disc carrying / playing unit 200 moves down to the home position and the switch 308 is turned on. However, if there is a command to play the disk 1 stored in the stocker 100 in addition to the disk 1 that was playing, the disk transport / play unit 200 does not move to the home position after the performance ends, and The tray 104 on which the disk 1 scheduled to be played is moved to a position where the tray 104 can be pulled out, and similarly, the tray 104 on which the disk 1 is placed is pulled out, and the performance of the disk 1 is started.

From the above, it is possible to perform the desired performance of the discs 1 stored in the stocker 100 and the continuous performance of the discs 1 containing 50 discs.

A stocker in which the inner tray 4 can be pulled out at the home position of the disc carrying / playing unit 200.
By placing the loading tray 2 at the bottom of 100,
When playing the disc 1 outside the apparatus, the loading tray 2 is caused to project outside the apparatus by the loading motor 3 in response to the opening instruction of the loading tray 2.
(Indicated by a chain double-dashed line in FIG. 2). At this time, the inner tray 4
Is held by the loading tray 2, and thus projects out of the apparatus together with the loading tray 2. The disc 1 is mounted on the disc mounting surface 6 of the inner tray 4 which is held in the loading tray 2 and protrudes out of the apparatus.

When the loading tray 2 is closed, the loading tray 2 is stored in the apparatus, the inner tray stopper 5 is opened by the tray transfer means, and the inner tray 4 on which the disc 1 is placed is placed on the disc playing unit 202.
