Description

Disk device, disk transport device

technical field

The present invention relates to a disc device configured to remove a desired disc from a plurality of stacked disc holding members, set it to a drive unit, and play the disc, and particularly relates to a disc device capable of holding a plurality of discs during disc playback. Improvement of a disc device in which a drive unit is inserted into a space formed by lifting and lowering of a member to play a disc, and a disc transfer device and a disc loading mechanism used therein.

Background technique

In the past, disc devices of the type in which a disc cartridge containing a disc is installed in the device and automatically play back the disc drawn from the disc cartridge have been widely used. Such a disk drive does not require the operation of inserting and ejecting disks one by one every time the disk is played, and thus has excellent operability.

However, as a disc cartridge that is attached to and detached from the device, sufficient strength is required to protect the plurality of discs held by it when it is taken out to the outside. Therefore, the wall of the disc cartridge main body is very thick. The overall size of the device is increased. In addition, grooves or rails for guiding are provided on the inner surface of the side wall of the disc case to pull out a tray or the like holding a disc in the disc case. When such grooves or rail portions are formed, the thickness of the side wall of the disc case increases further, and at the same time, the interval between adjacent disc holders also becomes wider, so the height dimension of the disc case increases, and the device for mounting it is also enlarged. change.

In addition, in order to pull out and play the disc stored in the disc cartridge, it is necessary to provide a sufficient space in the device, which increases the size of the device. In particular, when it is necessary to accommodate a DIN size of 180×50 (mm) or a double DIN size of 180×100 (mm), such as a vehicle-mounted disk device, the demand for miniaturization is high.

In order to meet this requirement, a disc device has been developed (Patent Document 1, Patent Document 2) that forms a disc case in a split type, and makes the drive assembly for disc playback into the disc mounted on the device by splitting. The space formed by the case, so that the disc can be played without pulling it out of the case. In this disc device, since there is no space for pulling out the disc for playback, the device can be miniaturized as a whole.

In addition, there has been proposed a disk device that does not use a detachable disk cartridge, but is provided with a disk holder capable of accommodating a plurality of disks in a stacked state in advance in the device, and the slave disk can be automatically accommodated with respect to the disk holder. Insert the disk inserted into the port, and at the same time, the stored disk can be automatically discharged. In this disc device, since the thickness of the disc cartridge and the opening and mechanism for attaching and detaching the disc cartridge are not required, the size of the disc device can be reduced. In particular, the invention disclosed in Patent Document 3 is provided with a disc holder that can be divided up and down like the above-mentioned divided disc case, and by inserting the drive unit into the divided disc holder, playback can be performed without pulling out the disc. Further miniaturization.

However, conventional disc devices using the above-mentioned divided disc cartridges and disc holders require a mechanism for individually raising and lowering disc holding members such as trays and disc holders in the disc cartridge. As a mechanism for this purpose, a structure in which a member joined to it is raised or lowered by sliding a plate having a linear or stepped cam in an oblique direction is generally used.

However, in this case, a space is formed by evacuating the disk holding member of either one of the upper and lower sides of the desired disk toward the upper and lower sides, so that the disk cartridge or The opening width of the disc holder increases or decreases. Therefore, useless space is generated above and below the disk holder depending on the division position of the disk cartridge or the disk holder.

Also, when the disk insertion port is set at the center in the height direction of the front plate of the disk device as in the disk device described in Patent Document 3, it is difficult to lay out the display unit or the operation unit. In particular, in a car-mounted disk drive, a larger display is required for reasons such as a navigation system or a DVD player, but it is difficult to arrange a large display if the disk insertion slot is located in the center of the front panel.

Also, as described above, in a disk device of the type that stores disks in disk holders provided in advance in the device, a disk loading mechanism for individually inserting and ejecting disks is required. As the disk loading mechanism, generally, a loading roller whose length is substantially equal to the disk insertion port and driven by a motor is used, and the loading roller in contact with the surface of the disk rotates in the insertion direction (forward direction) or the ejection direction (opposite direction), thereby Insert and eject the disc against the disc holder.

Then, in order to rotate the loading roller, it is necessary to arrange a driving unit such as a motor or a gear mechanism at either of both ends (left and right in the case of the horizontal direction) of the loading roller.

However, when the drive unit is arranged on one end side of the loading roller in this way, the loading roller and the disk insertion opening are arranged at positions deviated to either the left or the right when viewed from the front side of the disk device. In this way, in order to store the disk linearly fed from the loading roller into the disk holder, the disk holder must also be arranged at a position offset to the same side as the loading roller, and in the disk device, the capacity of the loading roller cannot be effectively utilized. Deep space on the side of the drive unit.

In order to cope with this problem, although it is also conceivable to set the drive assembly sent into the divided disk holder at the depth of the drive part, in consideration of the space required by the drive part and the drive assembly, in order to avoid the moving drive assembly and Interference and collision of the drive unit require both to be arranged with a sufficient distance between them, which increases the size of the entire disk drive.

In addition, the disk loading mechanism is arranged at a position spaced apart from the disk holder by a predetermined distance so that the loading roller does not hit the disk stored in the disk holder or the disk being played. For this reason, it is necessary to provide a member or mechanism for taking in the disk conveyed from the loading roller on the side of the holder for storing the disk, and a member or mechanism for pushing the disk to the side of the loading roller. Providing such a member or mechanism increases the space required for the disk holder and increases the size of the disk drive. Therefore, the advantage of not using a disk cartridge cannot be fully obtained.

The control by these control circuits is performed based on the detection results obtained by detection units such as switches and sensors arranged in various parts of the device, but these detection units will be described only when necessary for the following operations and will not be shown in the illustration.

[D. Role]

With regard to the operations of this embodiment as described above, first the outline of the operations will be described, and then the details of the disk loading (disk insertion and storage) operations, disk playback operations, and disk unloading (disk ejection) operations will be sequentially described.

[1. Outline of operation]

[1-1. Flow of operations at the time of disk loading]

First, an outline of the flow of operations at the time of disk loading will be described with reference to FIG. 95 . In FIG. 95 , M1 to M5 are symbols showing the above-mentioned motors, and the motors that operate according to the operation content are marked with ○ symbols. That is, the drive chassis elevating motor M2 is activated to move the drive chassis unit 40 to a position where the holder plate 11 for storing the disk D can be selected. Then, the cam gear driving motor M1 is actuated to slide the disk selectors 41A and 41B, place the loading roller 51 on the selected holder plate 11, and open the disk holder 10 so that the disk D can be inserted (the holder open position ( 1)). Then, the drive frame elevating motor M2 is actuated to lift the drive frame assembly 40 to a position where the disk can be loaded, that is, a position where the loading roller 51 is aligned with the disk insertion opening 31 .

In this state, the cam gear drive motor M1 is continuously actuated to move the loading roller 51 to the disk holder 10 side (rear), and the disk D can be held. Then, the gate 32 is opened, the disk insertion port 31 is opened, and the disk holding link 17, 18 of the disk holding mechanism 15 is rotated in the holder plate 11 for accommodating the disk D, and the engagement claws 17a, 17b are closed, and the disk holder 10 Open further so that the center of the holder plate 11 does not interfere with the insertion path of the disk (cage open position (2)).

Then, when the sensor detects the insertion of the disk from the disk insertion port 31, the loading motor M3 is activated, and the loading roller 51 rotates in the loading direction (forward direction). Thus, the disk D is fed into the disk holder 10 . Then, when the sensor detects that the disk D is completely accommodated in the disk holder 10, the loading motor M3 is stopped, and the rotation of the loading roller 51 is stopped. Then, the disk insertion port 31 is closed by the shutter 32 due to the actuation of the cam gear drive motor M1, and the disk D is held on the holder plate 11 by the loading roller 51 and the disk restraint members 25A, 5B.

The drive chassis elevating motor M2 is actuated so that the disc holder 10 housing the disc D is at the height of the initial position, and the drive chassis assembly 40 is moved. Then, the cam gear driving motor M1 is operated in the opposite direction to the above to disengage the disk restricting members 25A, 25B from the disk D, and the loading roller 51 is moved to the disk insertion port 31 side (forward) to be released from the disk D. In this way, in the disk holding mechanism 15 of the holder plate 11 that accommodates the disk D, the engagement claws 17a, 17b of the disk holding links 17, 18 are opened to hold the inner edge of the disk.

Next, the disk selectors 41A and 41B are slid to be disengaged from the disk holder 10, and the disk holder 10 is brought into a state where the holder plates 11 are in close contact with each other by the biasing force of the spring 14e. Then, the drive frame elevating motor M2 is activated to move the drive frame assembly 40 to the height of the initial position. When the disk D is unloaded, the above-mentioned operation sequence is reversed.

[1-2. Operation flow during disc playback]

Next, an outline of the flow of operations during disc playback will be described with reference to FIG. 96 . That is, the drive chassis lift motor M2 is actuated to move the drive chassis unit 40 to a position where the holder plate 11 storing the disc D to be reproduced can be selected.

Then, the cam gear drive motor M1 is actuated to slide the disk selectors 41A, 41B, and the disk holder 10 can be opened so that the loading roller 51 can be inserted into the selected holder plate 11 (holder open position (1)). . In this state, the cam gear drive motor M1 is continuously operated to move the loading roller 51 to the disk holder 10 side (rear), and at the same time, the disk restricting members 25A, 25B are moved in the direction of contacting the disk D, thereby Keep disk D.

In the disk holding mechanism 15 of the holder plate 11 accommodating the disk D, the engagement claws 17a, 17b of the disk holding links 17, 18 are closed to release the disk inner edge. Then, the holder plate 11 moves downward to open the disk holder 10 away from the disk D (holder open position (2)). Then, the disc holder 10 is further opened (holder open position (3)) so that the drive base 61 enters the lower part of the disc D released from the disc holding mechanism 15 and held by the loading roller 51 and the disc restraint members 25A, 25B.

The drive base 61 is rotated so that the drive unit 62 enters the space formed by thus opening the disk holder 10 . Now, the clamping ring 64a comes to the position corresponding to the top of the center hole of the disc D, and the turntable 63 comes to the position corresponding to the bottom of the center hole of the disc D. Then, the disk D is loaded on the turntable 63 by closing the grip ring 64 a while raising the drive chassis assembly 40 .

Then, the disk restricting members 25A, 25B are released from the disk D, and the loading roller 51 is also moved to the disk insertion port 31 side (forward) to be released from the disk. The suspension lock is released by the suspension lock mechanism 67 , so that the driving unit 62 is in a suspended state supported only by the buffer 66 . In the above state, the screw motor M4 is activated to send the pick-up assembly 65a to the inner periphery, the spindle motor M5 is activated to rotate the disk D, and the signal of the disk D is read by the pick-up assembly 65a moving in the radial direction of the disk. . After the disc playback is completed, the disc D is accommodated in the disc holder 10 by performing the reverse operation to the above.

[2. Details of operation of each part]

The operation of each part in the flow of the above operation will be described in detail below. In the following description, the description of the operation of each of the electric motors M1 to M5 and the gear mechanism corresponding thereto, which are prerequisites for the operation of each part, will be omitted. In addition, FIG. 97 shows the relationship between the operating position of the cam gear 21 and the holding and releasing of each part of the relative disk D, and the relationship with the open position of the disk holder 10 .

[2-1. At the time of disk loading]

First, the operation for storing a disk in the disk holder 10 will be described. In the following description, an example in which disks are housed in the empty holder plate 11 on the third stage from the bottom will be assumed. That is, when the holder plate 11 of the 3rd floor is empty, as shown in Figure 56 (A), (B), the front ends of the middle stage cams 41Ac, 41Bc of the disc selectors 41A, 41B become empty with the 3rd floor. The protrusions 14 a of the holder plate 11 move the drive frame elevating plates 34A, 34B at the same height, thereby lifting the drive frame assembly 40 . At this time, the cam gear 21 is at the initial position as shown in FIG. 23 .

Then, as shown in FIG. 24, the cam gear (camgia) 21 is rotated in the loading direction (counterclockwise in the figure), so that the disc selector drives the control cam 21b and the disc selector plates 24D, 24C, 24B, and 24A. When the selectors 41A, 41B slide and move to the cage open position (1), as shown in Fig. 57(A) and (B), the protrusion 14a of the cage plate 11 of the third layer enters the middle cam 41Ac, 41Bc, and the third stage The protrusions 14a of the cage plates 11 of the fourth layer and above are lifted by the upper cams 41Aa, 41Ba, and the protrusions 14a of the cage plates 11 of the second layer and below are pressed down by the lower cams 41Ab, 41Bb. Therefore, a gap into which the disk D and the loading block 50 can be inserted is formed above and below the third stage holder plate 11 .

Then, the drive chassis elevating plates 34A, 34B are moved to move the drive chassis assembly 40 so that the gap on the third stage holder plate 11 and the position of the loading roller 51 coincide with the disk insertion port 31 . Then, as shown in FIG. 25, the cam gear 21 is further rotated toward the loading direction, and as shown in FIG. , So, the right loading block sliding plate 26 moves backward. On the other hand, as the right loading block sliding plate 26 moves, the pin 27b inserted into the cam hole 26c is biased to the right, so the shutter connecting plate 27 slides to the right. In this way, the pivot plate 34 that engages the pin 34a to the recessed portion 27a of the shutter link plate 27 pivots, so the slide link 36 is energized to slide to the left.

As shown in FIG. 47 , the slide link 36 energizes the gate opening and closing plate 33 to the left, so the gate opening and closing plate 33 slides to the left, thereby upwardly energizing the pin 32a inserted through the inclined cam hole 33a. Empowerment. Therefore, the shutter 32 provided with the pin 32a is raised, and the disc insertion port 31 is opened. Simultaneously, the sliding link 36 moves to the left to make the rotary link 37 turn around, and the left loading block sliding plate 38 connected with it slides and moves towards the rear. As above, when the right loading block sliding plate 26 and the left loading block sliding plate 38 move backward, since the protrusion 52 at the right end of the loading block 50 engages with the hole 26a of the right loading block sliding plate 26, the pin 53 at the left end engages. Because of the groove 38a of the left loading block slide plate 38, the loading block 50 slides backward as shown in FIGS. 2 and 72 . Then, as shown in FIG. 74 , the loading roller 51 is in a state where the roller gear 51 a is engaged with the gear 44 a of the loading gear mechanism 44 and can be rotated by the loading motor M3 .

On the other hand, by turning the cam gear 21 in the loading direction from the initial position shown in FIG. Position (2), therefore, the disk restricting plate 25F slides to the right. In this way, the cam hole 25Ec of the disk restricting plate 25E is energized by the pin 25Fa of the disk restricting plate 25F, and the disk restricting plate 25E slides forward. Thus, the cam holes 25Ea, 25Eb of the disk restricting plate 25E energize the pins 25Cb, 25Db of the disk restricting links 25C, 25D, so that the disk restricting link 25C rotates counterclockwise, and the disk restricting link 25D rotates clockwise. Rotate, and its shaft 25Ca, 25Da moves toward the direction (front) which contacts the edge of disk D.

By the movement of such shafts 25Ca and 25Da, the disk restricting members 25A and 25B also move forward. In this way, the convex portion 25Aa of the disk restricting member 25A energizes the pressed portion 16a of the disk holding arm 16, so that, as shown in FIGS. closure. In addition, as shown in FIG. 25, as the cam gear 21 further rotates, as shown in FIGS. The projections 14a of the third stage holder plate 11 are energized downward by the middle stage cams 41Ac and 41Bc, and the space below the disk D is further expanded.

When the sensor detects that the disk D has been inserted through the disk insertion port 31 from the above state, the loading roller 51 rotates in the normal direction, and the disk D is drawn into the apparatus. In the process of drawing in this way, the disc D is retracted between the upper clamp ring 64a and the lower turntable 63 as shown in FIG. 61 . Then, the right edge of the disk D is energized by the energizing guide member 55. At the same time, as shown in FIGS. , is guided to the obliquely upper right direction when viewed from the plane direction. Thereafter, as shown in FIG. 2 , when the sensor detects that the rear edge of the disk D is held by the holding portions 25Ab, 25Ba of the disk restricting members 25A, 25B and the disk is housed in the disk holder 10, the loading roller 51 stops. .

Then, the cam gear 21 is rotated in the direction opposite to the above, and as shown in FIG. The protrusions 14a of the upper side are energized upward by the mid-stage cams 41Ac, 41Bc, so that the holder plate 11 of the third layer rises, and its center is aligned with the center hole of the disk D held by the disk restraining members 25A, 25B and the loading roller 51.

In addition, by the rotation of the cam gear 21, as shown in FIG. 39, the pin 26b in the loading block drive control cam 21e enters the release position (0) from the holding position (2), so the right loading block slide plate 26 faces forward. Simultaneously with the movement, the slide link 36 operates in the opposite direction to the above, thereby lowering the shutter 32 and closing the disc insertion port 31 .

At this time, the drive chassis elevating plates 34A, 34B are slidably moved so that the disk holder 10 is at the height of the initial position, and the drive chassis assembly 40 is moved. Simultaneously, along with the movement of the sliding link 36, contrary to the above loading, the left loading block sliding plate 38 slides forward. As described above, when the right loading block sliding plate 26 and the left loading block sliding plate 38 move forward, the loading block 50 is slid forward and separated from the disk D. As shown in FIG.

On the other hand, as shown in FIG. 32, the pin 25Fb in the disk restricting plate 25F returns to the release position (1) in the disk restricting member drive control cam 21d, so the disk is moved by the disk restricting plate 25F and the disk restricting plate 25E. The restricting link 25C rotates clockwise, the disk restricting link 25D rotates counterclockwise, and the axes 25Ca, 25Da move away from the edge of the disk D (backward). By the movement of the shafts 25Ca and 25Da, the disk restricting members 25A and 25B also move backward, and the gripping parts 25Ab and 25Ba release the disk D. As shown in FIG. In addition, the convex portion 25Aa of the disk restricting member 25A releases the pressed portion 16a of the disk holding arm 16, so, as shown in FIGS. Engages with the inner edge of the pan.

In the state where the disk D is set on the holder plate 11 in this way, the cam gear 21 turns to the position shown in FIG. Initial position (0), at this time, the protrusions 14a of the holder plate 11 are released from the disk selectors 41A, 41B, so the holder plates 11 are moved toward each other by the urging force of the spring 14e, and the disk holder 10 is closed. Then, the drive frame assembly 40 is moved to the height of the initial position by slidingly moving the drive frame elevating plates 34A, 34B.

[2-2. At the time of disc playback]

Next, the operation of each part during disc playback will be described. In addition, in the following description, an example in which the disk D held by the holder plate 11 on the third stage from the bottom is played will be described. That is, as shown in FIG. 56(A), (B), the front ends of the middle stage cams 41Ac, 41Bc of the disk selectors 41A, 41B are positioned at a height consistent with the protrusion 14a of the holder plate 11 of the third layer to drive The movement of the frame lift plates 34A, 34B moves the drive frame assembly 40 .

Then, as shown in FIG. 26 , the cam gear 21 is rotated toward the playing direction (clockwise in the figure), so that the disk selectors 41A, 41B are slid to move to the cage open position (1). At this time, as shown in FIG. As shown in 57, the protrusions 14a of the cage plate 11 of the third layer enter the middle cams 41Ac, 41Bc, the protrusions 14a of the cage plate 11 of the fourth layer and above are lifted by the upper cams 41Aa, 41Ba, and the second and The protrusion 14a of the holder plate 11 below it is pushed down by the lower cam 41Ab, 41Bb. Therefore, a gap into which the load block 50 can be inserted is formed above and below the disk D provided on the holder plate 11 of the third stage.

In this state, when the cam gear 21 is further rotated toward the playback direction, as shown in FIG. The block slide plate 26 moves backward. On the other hand, as the right loading block slide plate 26 moves, the pin 27b inserted through the cam hole 26c is energized to the right, so the shutter connecting plate 27 slides to the right. In this way, similarly to the above, the turning plate 34 turns and the sliding link 36 slides leftward, so the left loading block sliding plate 38 slides backward through the turning link 37 . As described above, when the right loading block sliding plate 26 and the left loading block sliding plate 38 move rearward, the loading block 50 slides and moves rearward in the same manner as above, and the loading roller 51 clamps the disk D.

At this time, as shown in FIG. 33, the pin 25Fb of the disk restricting plate 25F enters the holding position (2) from the release position (1) of the disk restricting member drive control cam 21d, so the disk restricting links 25C, 25D pass through the disk. The restricting plates 25F, 25E move in the direction (forward) in which the shafts 25Ca, 25Da approach the edge of the disk D. As shown in FIG. By such movement of the shafts 25Ca, 25Da, as shown in FIGS. 2 and 20 , the disk restricting members 25A, 25B also move forward, and the edge of the disk D is gripped by the gripping portions 25Ab, 25Ba of the disk restricting members 25A, 25B. In addition, the convex portion 25Aa of the disk restricting member 25A energizes the pressed portion 16a of the disk holding arm 16, so that the disk holding links 17, 18 rotate, the engagement claws 17a, 17b close, and the disk inner edge is released.

In this way, the disk D is gripped by the disk restricting members 25A, 25B and the loading roller 51, and the inner edge of the disk is released. When the cam gear 21 further rotates in the playback direction, during this process, as shown in FIG. 41A, 41B slides to the open position of the cage (3), and the protrusion 14a of the cage plate 11 of the third layer is energized downward by the mid-section cams 41Ac, 41Bc, so the cage plate 11 of the third layer descends from the disk. D leaves, and the space below disk D expands.

Then, as shown in FIG. 27, when the rotation of the cam gear 21 is further carried out, the disc selectors 41A, 41B move to the cage open position (3), and as shown in FIG. 59, the cage plate 11 of the third layer is The protrusion 14a merges with the lower cam 41Ab, 41Bb, the protrusion 14a of the upper cage plate 11 moves to the uppermost stage of the upper cam 41Aa, 41Bb, and the protrusion 14a of the cage plate 11 after the third stage moves to the lower cam 41Ab, 41Bb. bottom paragraph. For this reason, the disk holder 10 is further divided to form a space above and below the disk D into which the drive base assembly 60 can enter.

In addition, with the rotation of the cam gear 21 as described above, the drive assembly shown in FIG. 43 drives the control cam 21c to move, so the pin 28b inserted therein enters the rotation position, thereby causing the drive base drive plate 28 to slide rightward. move. In this way, as shown in FIG. 79 , the drive displacement plate 68 is slidably moved to the right by the pin 68a engaged with the hole 28a of the drive plate 28 of the drive base. In this way, as shown in FIG. 88, the drive base 61 is energized by the connecting shaft 67a inserted through the cam hole 68b of the drive displacement plate 68 and the cam hole 61a of the drive base 61, and begins to rotate counterclockwise in the figure. At this time, the connecting shaft 67a moves in the arc-shaped portion of the cam hole 40c of the drive frame assembly 40 as shown in FIG. 93 .

When the drive base 61 rotates in this way, the guide hole 72a is energized by the guide pin 61b of the drive base 61, so that the drive support plate 72 is rotated clockwise. Then, the drive base 61 stops rotating when the guide pin 61b reaches the end of the guide hole 72a. At this time, as shown in FIG. 87, the turntable 63 of the drive unit 62 is positioned below the center of the disk D held by the disk restricting members 25A, 25B and the loading roller 51, and the clamp ring 64a is positioned above.

Then, the drive frame lifting plates 34A, 34B make the drive frame assembly 40 rise, and at the same time, when the drive shift plate 68 continues to slide to the right, as shown in Figure 94, the connecting shaft 67a of the sliding locking plate 69 enters The linear portion to the cam hole 40c of the drive frame assembly 40 moves. Like this, as shown in Fig. 89, Fig. 92 (A)～(B), slide lock plate 69 moves, and lifting portion 67b disengages from energizing roller 64c, so, by the energizing force of spring, clamp arm 64 toward Rotating below, the clamping ring 64 a pushes the disc against the turntable 63 .

When the cam gear 21 rotates in this way, under the state that the disk D is clamped on the turntable 63, the pin 26b in the loading block drive control cam 21e enters the release position (0) from the holding position (1) shown in FIG. 39, so , the right loading block sliding plate 26 moves forward. Simultaneously, the left loading block slide plate 38 also slides forward as mentioned above, so the loading block 50 slides forward to release the disk D.

On the other hand, by the rotation of the cam gear 21, the pin 25Fb of the disk restricting plate 25F is moved from the holding position (2) of the disk restricting member drive control cam 21d shown in FIG. The plate 25F and the disk restricting plate 25E rotate the disk restricting link 25C clockwise, the disk restricting link 25D rotates counterclockwise, and the shafts 25Ca, 25Da move away from the edge of the disk (rearward). By the movement of such shafts 25Ca and 25Da, the disk restricting members 25A and 25B are also moved backward, and the gripping parts 25Ab and 25Bb release the disk D. As shown in FIG.

Then, as the sliding lock plate 69 moves, as shown in FIGS. The lock pin 62b and the lock groove 62c are disengaged. Then, the rotation lock plate 70 and the hook plate 71 are also rotated, and the lock pin 70 a and the hook 71 a are disengaged from the lock groove 62 c and the pin 62 a of the driving assembly 62 . In this way, the drive unit 62 is in a suspended state elastically supported only by the damper 66 .

In this way, the disk is set on the turntable 63, its surroundings are released, and at the same time, it is in a floating state. After that, the pick-up unit 65a is moved to the inner periphery of the disk, and the turntable 63 is rotated. Then, the signal of the disk D is read while the pickup unit 65a is moved in the radial direction of the disk.

[2-3. At the end of disc playback]

Next, the operation of each part when the disk D is returned to the disk holder 10 at the end of the disk playback will be described. In the following description, an example in which the disk D is returned to the holder plate 11 on the third stage from the bottom will be described.

That is, after the disk is played, when the cam gear 21 rotates toward the direction of the initial position shown in FIG. Swipe left to move. In this way, the drive displacement plate 68 is slidably moved to the left by the pin 68a engaged in the hole 28a of the drive plate 28 of the drive base.

In this way, as shown in FIG. 94, the connecting shaft 67a inserted through the cam hole 68b of the drive displacement plate 68 is energized to the left, so that the linear portion of the cam hole 40c of the drive frame assembly 40 faces left. party moves. By the movement of the connecting shaft 67a, as shown in Fig. 89, Fig. 91 (C) - (A), and Fig. 92 (C) - (A), the sliding locking plate 69 which is fixed also slides on the drive base 61. , Therefore, the locking groove 69a and the locking pin 69b are engaged with the locking pin 62b and the locking groove 62c of the drive assembly 62 . Then, as the slide lock plate 69 moves, the rotation lock plate 70 and the hook plate 71 also rotate, and the lock pin 70 a and the hook 71 a are engaged with the lock groove 62 c and the pin 62 a of the driving assembly 62 . In this way, the drive unit 62 is in a locked state where it is pressed and fixed to the bumper 66 .

At the same time, by the rotation of the cam gear 21 towards the initial position, as shown in Figure 40, the pin 26b in the loading block drive control cam 21e enters the holding position (1) from the release position (0), so the right loading block sliding plate 26 moves towards the rear. On the other hand, as the right loading block slide plate 26 moves, the pin 27b inserted through the cam hole 26c is energized to the right, so the shutter connecting plate 27 slides to the right. In this way, similarly to the above, the turning plate 34 turns and the sliding link 36 slides leftward, so the left loading block sliding plate 38 slides backward through the turning link 37 . When the right loading block sliding plate 26 and the left loading block sliding plate 38 move rearward as described above, the loading block 50 slides backward and the loading roller 51 clamps the disk D in the same manner as above.

In addition, the pin 25Fb of the disk restricting plate 25F enters the holding position (2) from the release position (1) of the disk restricting member drive control cam 21d as shown in FIG. Shafts 25Ca, 25Da of rods 25C, 25D move toward the edge of the disk (forward). By the movement of the shafts 25Ca and 25Da, the disk restricting members 25A and 25B also move forward, and the edge of the disk D is held by the holding parts 25Ab and 25Ba.

Then, with the movement of the slide lock plate 69 as described above, as shown in Fig. 92(C) and (A), the raised portion 67b comes into contact with the energizing roller 64c, so the clamp arm 64 is moved against the energizing force of the spring. Turning upward, the clamping ring 64a is separated from the disc D. As shown in FIG. In this way, the disk D is gripped by the loading roller 51 and the disk restricting members 25A, 25B, and is released from the clamp ring 64a and the turntable 63. In this state, when the rotation of the cam gear 21 is further progressed, the drive base drive plate 28 is further to the left. Square swipe to move. Thus, the drive displacement plate 68 is slidably moved to the left by the pin 68a engaged with the hole 28a of the drive plate 28 of the drive base.

Like this, as shown in Figure 88, through the connecting shaft 67a inserted in the cam hole 68b of the driving displacement plate 68 and the cam hole 61a of the driving seat 61, the driving seat 61 is energized toward the left, and moves forward in the direction of the figure. Turn clockwise. At this time, the connecting shaft 67a moves in the arc-shaped portion of the cam hole 40c of the drive frame assembly 40 as shown in FIG. 93 . When the drive base 61 rotates in this way, the guide pin 61b of the drive base 61 energizes the guide hole 72a, so that the drive support plate 72 is rotated counterclockwise. Then, as shown in FIG. 77, the drive base 61 stops turning when the connecting shaft 67a reaches the end of the cam hole 40c and returns to the initial position.

With the rotation of the cam gear 21 as described above, as shown in FIG. 26 and FIG. Since the middle cams 41Ac and 41Bc are energized upward, the holder plate 11 of the third stage rises and its center is aligned with the center hole of the disk D held by the disk restricting members 25A, 25B and the loading roller 51 .

Then, by the rotation of the cam gear 21, as shown in FIG. 32, the pin 25Fb of the disk restricting plate 25F returns to the release position (1) of the disk restricting member drive control cam 21d, so the disk is restricted by the disk restricting plates 25F, 25E. The links 25C, 25D move in directions in which their axes 25Ca, 25Da separate from the edge of the disk D (rearward). By the movement of the shafts 25Ca and 25Da, the disk restricting members 25A and 25B also move backward, and the gripping parts 25Ab and 25Ba release the disk D. As shown in FIG. In addition, the convex portion 25Aa of the disk restricting member 25A releases the pressed portion 16a of the disk holding arm 16, so, as shown in FIGS. Engages with the inner edge of the pan.

At the same time, as shown in FIG. 39, the pin 26b in the loading block drive control cam 21e enters the release position (0) from the holding position (1), so the right loading block slide plate 26 moves forward. Simultaneously, similarly to the above, along with the movement of the slide link 36, the left loading block slide plate 38 moves forward. Thus, the loading block 50 slides forward and the disk D is released.

With the disk set on the holder plate 11 in this way, as shown in FIG. 23 and FIG. 56, when the disk selectors 41A, 41B slide to the initial position (0), the protrusion 14a of the holder plate 11 moves from the disk to the initial position (0). The selectors 41A, 41B are released, so the disk holder 10 is closed as described above. Then, the drive frame assembly 40 is moved to the height of the initial position by slidingly moving the drive frame elevating plates 34A, 34B.

[2-4. At the time of disk loading]

Next, the operation of each part when the disc D is ejected from the apparatus will be described. In the following description, an example in which the disk D is ejected from the holder plate 11 on the third stage from the bottom will be described. That is, when the disk D is stored in the holder plate 11 of the third stage, when an instruction to discharge the disk D is input, as shown in FIG. The drive frame elevating plates 34A, 34B are moved so that the front end of the drive frame assembly 40 is at the same height as the protrusion 14a of the holder plate 11 of the third layer, thereby lifting the drive frame assembly 40 . At this time, the cam gear 21 is at the initial position as shown in FIG. 56 .

Then, as shown in FIG. 57 , the cam gear 21 is rotated in the loading direction, and the disk selectors 41A, 41B are slid to the holder through the disk selector drive control cam 21b, disk selection plates 24D, 24C, 24B, and 24A. Open position (1), at this time, as shown in Figure 58, the protrusions 14a of the third layer of the cage plate 11 enter the middle cams 41Ac, 41B, and the protrusions 14a of the fourth layer and above the cage plate 11 are moved by The upper cams 41Aa, 41Ba are raised, and the protrusions 14a of the second and lower retainer plates 11 are pushed down by the lower cams 41Ab, 41Bb. Therefore, a gap into which the disk D and the loading block 50 can be inserted is formed above and below the holder plate 11 on the third stage.

Then, the drive chassis elevating plates 34A and 34B are moved so that the gap on the third stage holder plate 11 and the position of the loading roller 51 are aligned with the disk insertion opening 31, thereby moving the drive chassis assembly 40. When the cam gear 21 is rotated like this, as shown in FIG. 41, the pin 26b in the loading block drive control cam 21e enters the holding position (2) from the release position (0), so the right loading block slide plate 26 moves backward. On the other hand, as the right loading block sliding plate 26 moves, the gate connecting plate 27 slides to the right, so as described above, the gate opening and closing plate 33 is moved to the left through the rotary plate 34 and the slide link 36 .

By such movement of the shutter opening and closing plate 33 , as shown in FIG. 47 , the shutter 32 is raised to open the disk insertion opening 31 . Simultaneously, the sliding link 36 slides the left loading block sliding plate 38 towards the rear through the rotary link 37 . As described above, by moving the right loading block sliding plate 26 and the left loading block sliding plate 38 rearward, the loading block 50 is slid backward, and the disk is clamped by the loading roller 51 . At the same time, the loading roller 51 is in a state where it can be rotated by the loading motor M3. The end of the energizing guide member 55 is in contact with the right edge of the disc D as shown in FIGS. 2 and 60 .

On the other hand, the pin 25Fb of the disk restricting plate 25F enters the holding position (2) from the release position (1) of the disk restricting member drive control cam 21d shown in FIG. 25F and the disk restricting plate 25E move toward the direction (forward) in which the shafts 25Ca and 25Da approach the edge of the disk D. By such movement of the shafts 25Ca, 25Da, as shown in FIGS. 2 and 20 , the disk restricting members 25A, 25B also move forward, and the edge of the disk D is gripped by the gripping portions 25Ab, 25Ba of the disk restricting members 25A, 25B. In addition, the convex portion 25Aa of the disk restricting member 25A energizes the pressed portion 16a of the disk holding arm 16, so that the disk holding links 17, 18 rotate, the engagement claws 17a, 17b close, and the inner edge of the disk D is released.

Then, as shown in FIG. 25, as the cam gear 21 rotates in the loading direction, the disk selectors 41A, 41B slide and move to the holder open position (2), so, as shown in FIG. The shelf plate 11 descends downward through its protrusion 14a being energized downward by the mid-section cams 41Ac and 41Bc, and the space below the disk is further expanded.

As described above, when the loading roller 51 rotates in the opposite direction with the disk released from the holder plate 11 , the disk starts to move in the direction of ejection from the disk holder 10 . In this process, the disk D is guided in the obliquely lower left direction when viewed from the planar direction as shown in FIG. 42 of the inclined surface 42a, thereby changing the advancing path to a direction perpendicular to the loading roller 51, as shown in FIG. Then, the disk D is ejected from the disk insertion port 31 opened by the lift of the shutter 32, and the disk D protruding from the device is pulled out by hand, so that the disk D can be completely taken out.

[E.Effect]

According to the above embodiment, as shown in A of FIGS. 11 to 13 , the opening amount of the disk holder 10 due to the lifting and lowering of the holder plate 11 is constant, so the disk will not be distorted depending on which disk D is played. The space required for the upper and lower sides of the holder 10 is different, and the space in the device can be effectively used.

In addition, as shown in FIG. 16, since the height at which the disk D is inserted is offset upward between a certain amount of opening of the disk holder 10, the disk insertion port 31 can be provided offset upward. Therefore, compared with the case where it is installed in the center of the front panel, the space for arranging the display unit or the operation unit can be increased. This is advantageous when a disk drive with a large display is required, such as a navigation system or a DVD player. On the other hand, since the opening amount of the disc holder is constant, as shown in FIG. As shown in FIG. 15, the opening amount of the disk holder 10 at the time of disk insertion becomes larger than the opening amount of the disk holder 10 at the time of playback, so that the required space is not enlarged unnecessarily.

In addition, the desired holder plate 11 is held by the middle cams 41Ac, 41Bc of the disk selectors 41A, 41B when the disk is inserted, and the desired holder plate 11 is retracted downward by the lower cams 41Ab, 41Bb when the disk is played. , the disk insertion position can be biased upward as described above, and at the same time, the space in the upward direction can be prevented from being enlarged.

In addition, if the drive frame assembly 40 is raised and lowered when a desired holder plate 11 is selected, the loading roller 51, the disk selectors 41A, 41B, and the drive assembly 62 mounted thereon will be raised and lowered while keeping a certain distance from each other. Therefore, the intervals between the insertion position of the disk D, the dividing position of the disk holder 10, and the playback position of the disk D are always constant. Therefore, stable operation can be performed and reliability can be improved.

In addition, in the state where the disk D is gripped by the disk restricting mechanism 25, all the upper and lower holder plates 11 of the desired disk D are retreated by the disk selectors 41A, 41B, and the drive unit 62 enters the space, and the desired disk D is selected. The disc D is set on the turntable 63. Therefore, in order to transfer the disk D from the holder plate 11 to the drive unit 62, the specific holder plate 11 does not need to perform complex operations, and the disk selectors 41A, 41B and their drive mechanisms can be simplified.

In addition, the disk holder 10 is set at a position where the center of the hole 11a is slightly shifted to the right from the center of the disk insertion opening 31 when viewed from the planar direction. In this way, the center of the disk D stored in the disk holder 10 is located on the right side relative to the center of the disk D passing the loading roller 51, and the disk holder is accommodated in the deep space of the loading motor M3 and the loading gear mechanism 44. Part of 10. Therefore, the space in the disk device can be effectively used.

In this way, even if the disc holder 10 and the loading roller 51 are arranged in a shifted manner, since the movement of the disc D is guided by the disc guide member 42, it can be reliably loaded into and out of the disc holder 10. In particular, the disc guide member 42 is a simple and compact member having only the inclined surface 42a on which the outer edge of the disc D contacts, so that the size of the device does not increase.

In addition, since the drive unit 62 is arranged in the space on the left side formed by disposing the disk holder 10 to the right side, the space can be effectively used, and the overall size of the device can be reduced. In particular, since the drive unit 62 is disposed on the opposite side to the loading motor M3 and the loading gear mechanism 44, mutual interference or collision can be prevented.

In addition, when the disc D is played, the disc D is clamped between the clamping ring 64a and the turntable 63, thereby enhancing the anti-vibration capability. When the disk D is transported, the disk D can pass between the clamp ring 64a and the turntable 63. Therefore, the drive unit 62 can be arranged at a position close to the loading block 50 and the disk holder 10, and the entire disk device can be miniaturized.

In addition, the disk selectors 41A, 41B, which require a small space, and the drive unit 62 and the loading block 50, which require a large space, are arranged at opposite positions so as to sandwich the disk holder 10, so that the depth direction and width of the disk device are not enlarged. One side of the direction can make the whole compactly concentrated.

In addition, the loading roller 51 itself moves in a direction to move away from the disk D, so that the disk D can be inserted into the disk holder 10 or pulled out from the disk holder 10 . Therefore, in order to take in the disk D fed from the loading roller 51 and eject the disk D to the loading roller 51 , no special member or mechanism is required for each holder plate 11 of the disk holder 10 . Therefore, the size of the disk holder 10 can be reduced, the required space can be saved, and the size of the entire disk device can be reduced. In addition, since the loading roller 51 is retracted from the disk D when the disk D is reproduced, a vibration-proof stroke that allows displacement during vibration can be ensured, and collision with the disk D can be prevented.

In addition, since the loading motor M3 and the loading gear mechanism 44 are fixed, and only the loading roller 51 moves, the moving part is the minimum necessary limit, and the space for securing the movement can be reduced, enabling miniaturization of the disk drive. In addition, since the loading roller 51 is used, the contact length with respect to the surface of the disk D is long. Therefore, when the loading roller 51 is brought into contact with and separated from the disk D for insertion and removal of the disk D, it is only necessary to simply slide forward and backward, and high precision is not required. In addition, the loading motor M3 and the loading roller 51 can be connected and disconnected by a simple method of engaging and disengaging the loading gear mechanism 44 and the roller gear 51a, so that the structure can be simplified and the reliability of operation can be ensured.

In addition, when a space is formed above and below a desired disk D for the drive unit 62 to enter, the desired disk D can be held by the loading roller 51, so there is no need to press the holder plate 11 holding the desired disk D. Continuing with complex operations such as the turntable 63, the retainer plate 11 can be retracted smoothly.
