9 sequentially meshes with gear B253, gear C254, and gear D255. The above-described operation is performed by rotating the gear A250 once.

Gear B253, gear C254, gear D255
The circular rotation restriction stoppers 275b, 275c, 275d are shown in the figure so that they do not rotate unnecessarily except when meshing with the gear A250.
As shown in Fig. 22 and Fig. 23, different gears and different heights are provided for each gear. Corresponding to the rotation restriction stoppers 275b, 275c, 275d of the gear B253, the gear C254, and the gear D255, the gear A250 has rotation restriction circles 270b, 270c, 270d, respectively. The rotation restriction circles 270b, 270c, 270d are the gear B253. , The rotation restriction stoppers 275b, 275c, and 275d rotate when the gear C254 and the gear D255 rotate, respectively.

Next, FIG. 26 is a plan view showing a state in which the intermediate chassis, the slider L, and the slider R are pulled out by the mechanism for moving the disc playing unit up and down, and the intermediate chassis is lowered.
(a), left side view (b), right side view (c), FIG. 27 shows a mechanism for moving up and down the disk playing unit, the intermediate chassis, the slider L,
A plan view (a), a left side view (b), a right side view (c) showing a state in which the slider R is pulled out and the intermediate chassis is raised is shown in FIG. 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 slider L261 and the slider R263, the recesses 284 at the ends are fitted with the projections 285 at both ends of the connecting arm 264, respectively, and the centers thereof are simultaneously moved through the connecting arm 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 the arrow B to above the disc mounting surface 106 of the tray 104, the disc 1 on the tray 104 turns to the turntable 204. Placed on top. Further, 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 a 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, the disc 1 rotates, and the signal of the disc 1 is read by the optical pickup 203.

Next, the operation of the tray transfer means will be described. First, in the operation of engaging and separating the hook 234 and the tray 104 with reference to FIG. 14, when the hook 234 moves in the stocker 100 direction (direction of arrow E) along the guide shaft 236, the unit chassis 201 near the stocker 100. Contact the upper protrusion 248. While the hook 234 contacts the protrusion 248,
By moving in the 100 direction (arrow E direction), 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), and at this position, the hook 234 contacts the protrusion 248 and rotates, and is separated from the tray 104. There is. In this initial position (see FIG. 7), the disc transporting / playing unit 200 can smoothly move in the directions of arrows A and B (see FIG. 2) with respect to the stocker 100.

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 protrusion 248 of the hook 234
Moves while rotating as indicated 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.

As a result, unlike the conventional example, a dedicated driving force is used to engage the tray 104 in the tray transfer means and to disengage and separate the tray 104 after returning it to the stocker 100. Instead, the operation of engaging and separating can be performed continuously with the operation of moving the hook 234 for transferring the tray 104.

Therefore, it is possible to reduce the dedicated driving force for engaging and separating the tray 104 and the parts related thereto, which leads to cost reduction, downsizing by reducing the exclusive space, and reliability improvement due to the small number of parts. Can be achieved. Further, the engagement between the hook 234 and the tray 104 and the subsequent movement thereof, the operation of returning the tray 104 to the stocker 100 and the subsequent separation thereof are smoothed only by linearly moving the hook support slider 235 along the guide shaft 236. Since it can be performed by a series of operations, it is not necessary to switch the operations such as stopping and starting the motor as in the case of using another power, and the operation time can be shortened. Further, the operation of engaging and separating the tray 104 and the hook 234, and the subsequent movement operation need only switch the moving directions of the hook 234 and the hook support slider 235, and become a very simple mechanism to improve reliability and parts. It is very effective in reducing the number.

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. Therefore, when the disc transport / performance unit 200 moves up and down with respect to the stocker 100,
It is possible to reduce the distance between the disc transporting / playing unit 200 and the tray 104 housed in the stocker 100, and it is possible to reduce the size of the apparatus by 2-3 mm. In this embodiment, the distance is 2 mm.

Next, as means for transferring the tray 104,
To move the hook support slider 235 shown in FIG. 15,
The hook support slider 235 is fixed to the timing belt 239, the timing belt 239 is supported by the first pulley 241 and the second pulley 243, and the driving means is connected via the first pulley 241 to drive the timing belt 239. I decided to do it.
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 position where the hook 234 is separated from the tray 104 is set so that the hook 234 is substantially above the second pulley 243.
(See Figure 7).

Now, the first pulley 241 and the second pulley 243
The space between the tray 104 and the transfer distance is required,
The position of the first pulley 241 is a condition for determining the depth dimension of the device, but in order to reduce the size of the device in the depth direction, the second pulley 243 and the hook 234 should be placed as close to the stocker 100 as possible. Good. At this time, the tray 104 needs a space for avoiding the hook 234 and a space for avoiding the second pulley 243. However, since the position where the hook 234 is separated from the tray 104 is above the second pulley 243,
Notch 276 that is a space to avoid the second pulley 243
(See FIGS. 16 and 18) avoids both the second pulley 243 and the hook 234, thus minimizing the width of the tray 104. Therefore, it is possible to reduce the size of the device, particularly the size of the depth without increasing the width in the width direction of the device.

Also, the first and second pulleys 241, 243
A guide shaft 236 for guiding the hook support slider 235 so as to be linearly movable is installed substantially above. As a result, the guide shaft 236 is installed on the unit chassis 201 of the disc transporting / playing unit 200 as compared with the case where the guide shaft 236 is arranged in parallel in the left-right direction of the timing belt 239 and the first and second pulleys 241 and 243. Since no space is required and the size of the unit chassis 201 in the width direction can be minimized, it is effective for downsizing the device, particularly for downsizing the device in the width direction.

Further, a shaft 242 is installed in the vertical direction to rotatably support the first pulley 241, and the second pulley 243 is installed.
Shaft 244 is installed in the vertical direction to rotatably support the shaft, and a guide shaft support hole 246 orthogonal to the axial direction is provided above the pulley support portion of the shaft 244 supporting the second pulley 243. A guide shaft 236, which guides the 235 so as to be linearly movable, is fitted into the guide shaft support hole 246 and installed. Accordingly, it is not necessary to provide a member for supporting the dedicated guide shaft, and the number of parts can be reduced by sharing the shaft 244 supporting the second pulley 243. Therefore, the cost can be reduced, and the size can be reduced by reducing the exclusive space.

Next, as a drive means for transferring the tray 104 on which the disc 1 is placed from the stocker 100 in which it is stored to the disc playing unit 202, a drive motor 252 shown in FIG.
And a gear A250 driven by the drive motor 252,
A gear B253 connected to and driven by the tray transfer means for transferring the gear A250 and the tray 104, and a 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).

In addition to the gears B253 and D255, a disc holding means (a mechanism for moving the disc playing unit 202 in a substantially vertical direction on the unit chassis 201, the disc 1 is provided between the clamper 210 and the turntable 204). The gear C254 for driving the holding mechanism) is driven. Further, the gear b257, the gear c258, and the gear d259 on the gear A250.
The drive motor 252 moves the gear A2 in one direction.
When 50 is driven to rotate, after the gear b257 drives the gear B253, the gear c258 drives the gear C254 which drives the disk holding means, and then the gear d259 drives the gear D255.
Configured to drive.

As a result, one drive motor 252 pulls out and stores the tray 104, and holds 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. And opening can be done. Therefore, by reducing the power to one, the number of parts can be reduced, space can be saved, and cost can be reduced. Further, the size can be reduced, the reliability can be improved due to the small number of parts, and the number of parts mounted on the unit chassis 201 can reduce the weight. It is possible to reduce the capacity of the lifting motor 212 for moving the unit chassis 201 up and down.

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
By rotating the tray in the opposite direction, the empty tray 104 can be pulled out, the disc 1 can be placed on the tray 104, and the disc 1 and the tray 104 can be returned to the stocker 100 by a series of operations. In operation, it is not necessary to perform switching operation such as motor stop, fast operating speed, short operating time,
Loading and unloading of the disk 1 to and from the stocker 100 can be performed.

Further, in the operation of the driving means, only two switches, that is, a detection switch 274 for detecting the end of the disc returning operation to the stocker 100 and a detection switch 268 for detecting the end of disc holding after the tray 104 is pulled out at the time of playing are used. Can be configured. When a motor is used for each of the transfer operation of the tray 104 and the elevating operation of the disk playing unit 202 for holding the disk 1 between the turntable 204 and the clamper 210, the tray pull-out completion detection, the tray return completion detection, the disk are detected. Detection of rising end of the playing unit,
Four detections of the descent end detection are necessary, but only two in the present embodiment. In the conventional example, four detection switches are used for the tray transfer operation and the disk holding operation.

Next, a tray stopper 105 for holding the tray 104 is provided in the stocker 100 for accommodating the tray 104 on which the disc 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
At the time of transfer to the position, the tray stopper 105 corresponding to the tray 104 is opened, and as a means for enabling transfer of the tray 104, the groove cam 251 mounted on the unit chassis 201 and provided on the flat portion of the gear A250. 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 driving groove cam 251 on the flat surface of the gear A250, there is no need for a dedicated member for driving the tray stopper opening / closing arm 249, and no dedicated power is required. Space can be reduced. Further, since the groove cam 251 is provided in the gear A250 which is the gear that determines the operation timing, the operation timing can be made accurate,
The tray stopper 105 can be opened immediately before the tray pull-out operation is started, so that no wasted time is generated and the operation time can be shortened.

Similarly, since the tray stopper 105 can be opened by a series of operations by the rotation of the gear A250, it is not necessary to switch the operation such as stopping the motor as compared with the case of using a dedicated power, and the operation is quick and quick. The detection switch for the end also uses the detection switch 274 described above, and it is not necessary to add a detection switch.

Further, on the tray stopper opening / closing arm 249,
A guide wall 287 for tray transfer is provided when the tray 104 is transferred (see FIGS. 16, 17, 18, 19, and 20). As a result, a smooth tray transfer operation can be performed, the number of parts can be reduced and the cost can be reduced by the combined use of parts, and the size can be reduced by reducing the exclusive space.

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, by the tray transfer means between the stocker 100 and the disc playing unit 202,
Prior to transferring the designated tray 104 in the stocker 100 to the position of the disc playing unit 202, that tray 104
The tray stopper opening / closing arm 249 which opens the tray stopper 105 corresponding to
Two vertical walls 260 are provided at the upper and lower sides of the tray 104 to be transferred when the tray is opened to prevent the tray 104 from which the holding is released from protruding from the stocker 100.

As a result, the tray stopper 105 is moved to the tray 1
It is possible to use one for each without having to provide each of 04. In this embodiment, 50 trays 104 on which the disks 1 are placed are stored, but one tray stopper 105 is used for each of the five trays 104, and a total of 10 tray stoppers are used. This is very effective in reducing the number of parts. Furthermore, since the tray stopper opening / closing arm 249 is provided with the vertical wall 260, the number of parts can be reduced and the cost can be reduced by also using the parts. Further, by being integrated with the tray stopper opening / closing arm 249, the operation of the tray stopper opening / closing arm 249 is utilized to sufficiently separate the tray 104 when the disc carrying / playing unit 200 is moved (see FIG.
6 and FIG. 17), when the tray 104 is pulled out, it can come close to the tip of the tray 104 that is not pulled out (see FIGS. 18 and 19).

In the case of the type fixed to the disc transport mechanism portion as in the conventional example, a tray pop-out prevention guide is provided at a slight distance from the tray 104 so as not to cause an inconvenience in the vertical movement of the disc transport mechanism portion. In this embodiment, compared to this fixed type, it is possible to prevent the tray 104 from popping out from the stocker 100 closer to the tray 104,
The range in which the tray 104 pops out in the stocker 100 can be reduced, which is effective for downsizing the apparatus.

Next, each drive operation will be described in order. Stocker
When playing a disc stored in 100, the disc transporting / playing unit 200 has a position of the lowermost loading tray 2, that is, a position where the inner tray 4 in the loading tray 2 can be pulled out onto the disc playing unit 202 (hereinafter , Home position) to the position of the tray 104 on which the disc 1 is instructed by the control unit.
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). When the gear A250 rotates in the direction of arrow M shown in FIGS. 16 and 21 (a), the tray stopper opening / closing arm 249 is driven by the groove cam 251 of the gear A250 to rotate, and the tray stopper 105 of the stocker 100 is opened (see FIG. 18, see Fig. 19).

The tray stopper 105 includes a plurality of (five) trays 1.
Since 04 is held, a plurality of (five) trays 104 are opened, but the vertical wall 2 at the tip of the tray stopper opening / closing arm 249
At this time, 60 is located at the tip of the tray 104 other than the purpose, and prevents unnecessary tray 104 from popping out while the apparatus is operating (FIG. 18,
(State of FIG. 19).

Next, the gear A250 shown in FIGS. 21, 22 and 23
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. 7). 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 disengagement of gear B253, and then gear A2
The gear c258 of 50 meshes with the gear C254 to drive the disc playing unit 202 up and down (see FIGS. 26 and 27).

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 is disengaged, the gear b257 of the gear A250 is reengaged 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. Thereafter, as shown in FIG. 16, the tray switch opening / closing arm 249 pushes the detection switch 274 to operate the control switch 274.
(Not shown) stops drive motor 252 and gear A250.

The same applies when playing the disc 1 on the loading tray 2.
The inner tray 4 on which the disc 1 therein is placed is pulled out to above the disc playing unit 202 to play as described above. At this time, the inner tray stopper 5 of the loading tray 2 is opened and closed by the tray stopper opening / closing arm 249.

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, the gear d259 of the gear A250 meshes with the gear D255. 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 A250 is rotating in the direction of the arrow M,
For gear B253, hook 234 in the stocker 100 direction (arrow E direction)
Drive to.

The path of the driving force for driving the hook 234 at this time is shown by the thick chain line in FIG. Gear B253 is gear D2
Since it is driven by 55, it rotates in the direction opposite to the direction of rotation when it meshes 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 detection switch 274 is operated by the tray stopper opening / closing arm 249 to drive the drive motor 252 and the gear A.
250 stops.

The disc carrying / playing unit 200 holding the disc 1 on the turntable 204 moves to the position of the tray 104 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 10
4 is pulled out. When the gear D255 is disengaged from the mesh of the gear d259, the gear c258 of the gear A250 then starts to mesh with the gear C254. The gear C254 drives the 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 disk 1 is placed on the tray 104, and the tray 104 on which the disk 1 is placed is stored in the stocker 100, as in the operation at the end of the performance.

The operation of unloading the disc 1 from the stocker 100 to the loading tray 2 is the same as the above-mentioned operation. First, the stocker 100 is accessed to access the disc 1
Is taken out and conveyed to the loading tray 2. The same can be done when transferring 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 a desired disc 1 is selected from the 50 discs 1 stored in the disc, the disc transport / play unit 200 is moved by the lifting motor 212 to the tray in which the desired disc 1 is stored from the home position. It is moved to a position where 104 can be pulled out. 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, spindle motor 20
5 is rotated, and the signal is read by the optical pickup 203 from the signal of the disk 1, so that the performance is performed.

When the performance is finished, 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. 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 Tray 10 with the disk 1 scheduled to be played
Move to a position where 4 drawers are possible,
The tray 104 on which is placed is pulled out, and the performance of the disc 1 is started.

From the above, the desired disc 1 stored in the stocker 100 can be played, and the disc 1 containing 50 discs can be continuously played.

Also, 50 stored in the stocker 100
When playing a disc 1 different from the one disc 1,
That is, when playing the disc 1 outside the apparatus, the loading motor 3 causes the loading tray 2 to project outside the apparatus in response to an opening command of the loading tray 2 (shown by a chain double-dashed line in FIG. 2). At this time, since the inner tray 4 is held by the loading tray 2,
It projects to the outside of the device 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. Pull out to. When the inner tray 4 is pulled out, the disc holding means holds the disc 1 between the turntable 204 and the clamper 210. When the spindle motor 205 rotates in this state, the disc 1 on the turntable 204 rotates, and the optical pickup 203 reads the signal to perform the performance.

Next, the operation of loading the disk 1 into the apparatus and storing the disk 1 in the stocker 100 will be described.

As described above, according to the disk playing device of the present invention, the disk playing means is mounted on the chassis and moved by the disk carrying means, so that the playing of the disk is performed in the space where the disk carrying means moves. It can be carried out. As a result, a space dedicated to the disc playing means is unnecessary, and the device can be downsized. Also,
When playing a desired disc stored in the disc storage portion, the chassis equipped with the disc playing means moves to a position corresponding to the tray on which the desired disc is placed, so that the desired disc is placed on the spot. The tray is pulled out onto the disc playing means, the disc is held by the disc playing means, and the playing is started.

Further, since the inner tray and the tray are provided with the notches opened toward the disc playing means, the inner tray and the tray are brought into contact with the turntable and the optical pickup after the disc is held by the disc playing means. Since the empty inner tray and the empty tray can be returned to the original state, the disk playing means can hold the disk on the turntable and carry it by the disk carrying means. In other words, the process of transporting the desired disc to the space dedicated to the disc playing means is omitted, so that the time from the input of the play start command to the start of the play can be shortened.

Further, since the loading tray having the inner tray removably attached thereto is provided, and the tray moving means capable of moving both the inner tray and the tray is provided, the disc is held on the turntable of the disc playing means so that the disc can be conveyed. , The disc can be automatically loaded or unloaded from the loading tray to the disc storage portion. Further, even when playing a disc other than the disc stored in the disc storage portion, the disc is loaded into the apparatus by the loading tray and the performance is immediately started like the disc stored in the disc storage portion.

Further, the hook-shaped hook engages with a hook engaging portion in the shape of a notch which is orthogonal to the tray transfer direction on a part of the tray, and guides straight from the disc storing portion to the disc playing means. It is movable and driven by the driving means. Further, the hook is rotatably supported on the hook support slider, and a member that abuts a part of the hook in the vicinity of the disk storage portion causes the hook to rotate around a rotation fulcrum and separate from the position at which the tray is engaged. Operates to move to a position. As a result, the engaging and separating operations can be performed continuously with the operation of moving the hook for transferring the tray. As a result, the operation time can be shortened without the need to switch the operation such as stopping and starting the motor when another power is used. Also, the hook engagement and separation operations need only change the moving direction of the hook support slider, and the reliability is improved and the number of parts can be reduced with a very simple structure.

Further, when the hook is at the second position separated from the tray, the hook is positioned substantially above the second pulley, so that the notch for avoiding the hook and the second pulley required for the tray is minimized. It can be limited. Therefore, the device can be downsized by reducing the space occupied by the tray.

Further, by providing the guide shaft for guiding the hook support slider so as to be linearly movable substantially above the first and second pulleys, it is possible to reduce the occupied space as compared with the case where the guide is arranged in parallel with the belt. Since the width of the chassis can be reduced, the device can be downsized.

Further, a hole for inserting a guide shaft for linearly moving the hook supporting slider is formed in a guide shaft supporting hole which is orthogonal to the axial direction above at least one pulley supporting portion of the first and second pulley supporting shafts. By providing the above, it is not necessary to provide a member for supporting the dedicated guide shaft, and the number of parts and the exclusive space can be reduced.

Further, the tray transfer means for moving the tray between the disk storage portion and the disk playing means and the disk holding means for holding the disk by moving the tray in a substantially vertical direction with respect to the clamper of the disk playing means are driven. Therefore, each part is operated in a continuous series of operations by the combination of the drive motor and the gear that transmits the driving force to each part. In each series of operations, it is not necessary to perform a switching operation such as stopping the drive motor, so that the operation can be performed quickly and in a short operation time.

Further, a tray stopper for holding the tray in the disc storage portion is provided, and a tray stopper opening member for opening the tray stopper before the tray is transferred is driven by a groove cam provided in the gear flat surface portion, whereby the tray is opened. A dedicated member for driving the stopper opening member is not required, and the number of parts and the exclusive space can be reduced. Further, since the grooved cam is provided on the plane portion of the gear that determines the operation timing, the operation timing can be made accurate and the operation time can be shortened without wasting time.

Further, by providing the guide wall on the tray stopper opening member, a smooth operation of tray transfer can be achieved and the size can be reduced by reducing the number of parts and the occupied space.

Further, the tray stopper which holds a plurality of trays at the same time with respect to the tray of the disc storage portion is effective in reducing the number of parts, and the tray stopper opening member for opening the tray stopper is provided with a vertical wall. The number of parts can be reduced by combining them.

As described above, the disk transporting and disk playing mechanisms are integrally configured to reduce the space, reduce the number of parts, and thereby reduce the cost and improve the assembling ability. An effect that a disc playing device that is easy to handle can be obtained.
