Abstract

PROBLEM TO BE SOLVED: To reduce the time required for a disk, which is housed in a cartridge, to be clamped even when the tray loading and the slot-in loading are made compatible. SOLUTION: When a read-only disk 30 in the tray is not detected by a sensor for detecting the existence of disk after the pull-in of the tray is completed, the mutually separating state is maintained for a clamper 60 and a turntable 72. When the cartridge is slotted in, a rewritable disk as the disk in the cartridge is clamped by the turning of a servo mechanism chassis 70 and the turning of a clamp arm 61 linked therewith. Therefore, the time of transportation by the tray is omitted even when the tray loading and the slot-in loading are made compatible, thence the time required for the disk, which is housed in the cartridge, to be clamped is reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables loading of a single disk and a disk housed in a cartridge, and in particular, the loading of the cartridge is a slot-in system, thereby shortening the loading time of the cartridge. Regarding drive device.

[0002]

2. Description of the Related Art In recent years, as an important recording medium in a multimedia society, a DVD having a storage capacity much larger than that of a conventional optical disk has been developed and attracted attention.

DVD includes a DVD-ROM as a read-only disc and a DVD as a rewritable disc.
-RAM, etc., especially for DVD-RAM,
Since it is necessary to protect the recording surface in order to guarantee repeated recording a predetermined number of times (for example, 1 million times), it is to be stored in a cartridge.

By the way, as a disk drive device which is compatible with the loading of a read-only disk, which is a disk alone which is not housed in a conventional cartridge, and a rewritable disk which is a disk housed in a cartridge, is disclosed in, for example, Japanese Unexamined Patent Publication (Kokai) No. 7-161112
The publication discloses a disk drive device as shown in FIG. That is, the tray 20 that can be inserted into and taken out of the opening 11 of the housing 10 is provided with a sub-tray 40 having an accommodating and retaining groove 41 for accommodating and retaining the read-only disc 30, and one end of the sub-tray 40 is provided. The portion 40a side is pushed up by a spring (not shown).

A rewritable disc 51 capable of recording and reproducing.
In this case, it is protected by the cartridge 50 having the shutter 52 that closes the window 53, and when the cartridge 50 is loaded on the tray 20, it is held by the front wall 21a and the side wall 21. Further, when the cartridge 50 is accommodated in the tray 20, the sub tray 40 is tilted by its weight until the sub tray 40 is in a substantially horizontal state, and an accommodation space for the cartridge 50 in the tray 20 is secured.

When the read-only disc 30 is loaded, the tray 20 is pulled into the housing 10 as shown in FIGS. 12 (a) and 12 (b). At this time, the clamper 60 supported by the clamp arm 61 and the turntable 72 rotatably supported by the output shaft of the spindle motor 71 mounted on the servomechanical chassis 70 are separated in opposite directions, The tray 20 is retracted to a position where it does not interfere with the pulling operation.

When the pull-in is completed, the clamp arm 61 rotates downward in synchronization with this, and the clamper 60 abuts on the upper surface of the central portion of the read-only disc 30, as shown in FIG. Next, the servomechanical chassis 70 is rotated upward, and the turntable 72 is moved to the read-only disc 3
The clamp operation is completed by abutting on the lower surface of the center portion of 0. Then, the pickup 73 reproduces information from the read-only disc 30.

When the tray 20 is pulled in, the engaging pin 81 hanging from the end of the shutter opening member 80 is moved outside the tray 20 as shown in FIGS. 13 (a) and 13 (b). The shutter opening member 80 is pushed by the peripheral edge portion and is pushed out to a position where it does not interfere with disk loading.

When the disc is ejected, the clamp arm 61 and the servomechanical chassis 70 rotate in opposite directions to release the clamp, and then the tray 20 is pushed out from the inside of the housing 10.

On the other hand, when the cartridge 50 containing the rewritable disc 51 is loaded, the cartridge 50 is accommodated in the tray 20 so that the cartridge 50 shown in FIG.
The tray 20 is pulled into the inside of the housing 10 in the same manner as 2 (a) to 2 (c). At this time, as shown in FIGS. 14A and 14B, the engagement pin 81 of the shutter opening member 80 engages with the edge portion of the shutter 52, and the shutter 52 is opened along with the retracting operation of the tray 20. . After that, as described above, the rewritable disc 51 in the cartridge 50 is clamped by the rotation of the clamp arm 61 and the servomechanical chassis 70, and information reproduction or information recording is performed.

When ejected, the clamp arm 61 and the servomechanical chassis 70 are also provided in the same manner as described above.
After the clamp is released by rotating in the opposite direction, the tray 20 is pushed out from the inside of the housing 10.

[0012]

As described above, in the above-mentioned conventional disk drive device, the tray 20 for carrying the read-only disk 30 is used to load the cartridge 50 containing the rewritable disk 51. Therefore, the read-only disk 30 and the rewritable disk 51 can be loaded at the same time.

However, since the above-mentioned disc drive device employs tray loading, it is necessary to eject the tray 20 once even when the rewritable disc 51 stored in the cartridge 50 is loaded. However, there is a problem that it takes time to clamp the rewritable disc 51 in the cartridge 50.

Incidentally, in the conventional disc loading method, in addition to the tray loading by the tray 20 described above, there is a slot-in loading for pushing the disc into the opening 11 of the housing 10, and in the case of the above read-only disc 30, Tray loading is preferable in terms of protection from scratches and dust, and slot-in loading is preferable in order to shorten the time until the disc is clamped.

Therefore, in order to solve the above-mentioned problems, the rewritable disc 51 is set to the tray loading in the case of the read-only disc 30 and the slot-in loading in the case of the cartridge 50.
It is thought that the time taken to clamp the can be shortened.

In this case, in order to insert the cartridge 50 into the slot, the tray 20 is returned to the inside of the housing 10 and mounted on the clamper 60 supported by the clamp arm 61 and the servomechanical chassis 70. It is necessary to separate the turntable 72 from each other, but in the conventional disc drive device, the tray 20 is used.
Even when only the cartridge is returned to the inside of the housing 10, the clamper 60 and the turntable 72 are in the clamped state, so that the slot-in loading of the cartridge 50 becomes impossible.

Moreover, as shown in FIG.
When 0 is pulled into the inside of the housing 10, the shutter opening member 80 is pushed to a position where it does not hinder disk loading, so even if the cartridge 50 can be slot-in, the shutter opening member 80 will The shutter 52 cannot be opened, and it becomes difficult to achieve both tray loading and slot-in loading.

The present invention has been made in consideration of such a situation, and even when the tray loading and the slot-in loading are compatible with each other, until the disc accommodated in the cartridge is clamped. A feature of the present invention is to provide a disk drive device capable of shortening the time.

[0019]

According to the first aspect of the present invention,
A disk drive device for loading a single disk by a tray that can be inserted into and taken out of an opening of a housing, and loading a cartridge containing a disk by slot-in from the opening. Disk presence / absence detection means for detecting the presence / absence of a single disk, cartridge detection means for detecting the slot-in of the cartridge, and the loaded disk single body and the center of the disk supported by a rotatable servomechanical chassis. It is supported by a turntable that can be brought into and out of contact with a portion and a clamp arm that is rotatable, and can be brought into and out of contact with the disk unit and the central portion of the disk in a direction facing the turntable. And a clamper for retracting the tray After the completion, if the disk itself in the tray is detected by the disc detecting means, together with the servo mechanical chassis is rotated,
When the clamp arm rotates in conjunction with this, the central portion of the disk unit is clamped between the turntable and the clamper, and after the tray is completely drawn in, the disk presence / absence detection unit detects the tray. If no single disk in the cartridge is detected, the clamper and the turntable are maintained in a state of being separated from each other, and the cartridge slot-in from the opening of the casing is detected by the cartridge detection means. At this time, after the slot-in of the cartridge is completed, the disc in the cartridge is clamped by the rotation of the servomechanical chassis and the rotation of the clamp arm interlocked with the rotation.

According to a second aspect of the present invention, the opening of the casing is rotatable to the outside of the casing and is closed by a lid having a cartridge insertion opening for the cartridge. The insertion opening is closed by an inner lid that is rotatable inside the housing.

According to a third aspect of the present invention, in the tray,
Side walls are provided only on both sides along the moving direction, and the tray is accommodated inside the housing,
When the cartridge is slotted in from the cartridge insertion port of the lid, the cartridge is inserted into the housing while being guided by the side wall.

According to a fourth aspect of the present invention, the shutter of the cartridge is opened inside the casing when the cartridge is slot-in, and is urged in the unloading direction by the elastic force of the elastic member. A shutter opening member is provided, and when the disk presence / absence detection unit detects a single disk in the tray after the tray is completely drawn, the shutter opening is performed in synchronization with the rotation of the servomechanical chassis. The member is retracted in a direction substantially orthogonal to the surface direction of the disc unit so as not to prevent the clamped disc unit from rotating, and after the tray is completely drawn in, the disc presence / absence detection unit detects the inside of the tray. If a single disk is not detected, it will be Characterized in that the shutter of the cartridge is opened by the shutter opening member.

According to a fifth aspect of the present invention, the servomechanical chassis is provided with a lock mechanism for fixing the slot-inserted cartridge at a clamp position, and after the slot-in of the cartridge is completed, the lock mechanism is provided. With the rotation of the servomechanical chassis, the cartridge is fixed to the clamp position by the lock mechanism, and at the time of ejecting, the lock by the lock mechanism is released with the reverse rotation of the servomechanical chassis,
It is characterized in that the cartridge is pushed out to the outside of the housing by the restoring force of the shutter opening member.

[0024]

In the disk drive device of the present invention, when the disk presence / absence detecting means detects the single disk in the tray after the completion of pulling in the tray, the clamp arm is rotated in association with the rotation of the servomechanical chassis. The center of the disc is clamped between the turntable and clamper, and after the tray has been pulled in, if the disc presence detection means has not detected the disc in the tray, the clamper and turntable When the cartridge detecting means detects the slot insertion of the cartridge from the opening of the housing, the servomechanical chassis is rotated and the clamp arm is interlocked with the rotation of the servo mechanical chassis. The disc inside the cartridge is clamped by rotating Since the way, it is possible to achieve both the tray loading and slot-in loading.

Further, the lid for closing the opening of the housing is rotatable to the outside of the housing, and the inner lid for closing the cartridge insertion opening provided on the lid is rotatable to the inside of the housing. Therefore, when the cartridge is slotted in, it is sufficient to simply insert the cartridge into the cartridge insertion port, and the time required for carrying by the tray can be saved.

Further, when the cartridge is slot-in, the side wall of the tray guides the insertion, so that the slot-in of the cartridge can be easily and surely performed.

Further, after the completion of pulling in the tray, when the disk presence / absence detecting means detects the single disk in the tray, the shutter opening member is clamped in synchronization with the rotation of the servomechanical chassis. When the tray is inside the housing, the shutter opening member is set to the standby position so that it does not interfere with the rotation, so the shutter opening member is placed in the standby position. Since it is possible to surely perform the shutter opening associated with the slot-in, it is possible to achieve both tray loading and slot-in loading.

After the completion of slot insertion of the cartridge, the cartridge is fixed to the clamp position by the lock mechanism as the servomechanical chassis rotates, and at the time of ejection, the cartridge is locked by the lock mechanism as the servomechanical chassis reversely rotates. Since the lock is released and the cartridge is pushed out to the outside of the housing by the restoring force of the shutter opening member, both tray loading and slot-in loading can be achieved.

It is arranged so that. Here, the turntable 72 is provided with a metal plate (not shown),
At the time of clamping, the central portions of the read-only disc 30 and the rewritable disc 51 are sandwiched between the turntable 72 and the read-only disc 30 by attraction between a metal plate and a magnet provided in a clamper 60 described later.

The rotation of the servomechanical chassis 70 is performed by a switching mechanism (not shown) for switching the driving force of the loading motor 17 shown in FIG. 9 described later.

Here, the loading motor 17 not only provides driving force for pulling in and ejecting the tray 20, but also rotational force for the servomechanical chassis 70, and switching of these driving forces is illustrated. Not to be done by a switching mechanism

Above the servomechanical chassis 70, the shaft 6
The servomechanical chassis 7 is provided with a clamp arm 61 that is rotatable about 2 as a fulcrum and that is urged by an elastic member (not shown) in the clamp releasing direction (the direction in which the clamper 60 separates from the turntable 72).
By the rotation of 0, the push-up member 74 protruding toward the servomechanical chassis 70 pushes up the rear end of the clamp arm 61, so that the clamp arm 61 rotates in synchronization with the rotation of the servomechanical chassis 70. It is supposed to do. At the tip of the clamp arm 61, a clamper 60 having a magnet (not shown) is loosely fitted and supported.

The reference numeral 2 is adapted to be tilted outward and downward against the biasing force of an elastic member (not shown).

The tray 20 is provided above the inside of the housing 10.
A disk presence / absence detection sensor 15 for detecting the presence / absence of the read-only disk 30 therein is provided, and the tray 20 is provided with the housing 10 without the read-only disk 30.
When the disk is detected inside and the disk presence / absence detection sensor 15 detects the absence of the disk, the servomechanical chassis 70 is not rotated by the control by the control system shown in FIG. 9, which will be described later. The separated state of the turntable 72 and the turntable 72 is maintained. This enables slot-in loading of the cartridge 50, the details of which will be described later.

Incidentally, the location of the disk presence / absence detection sensor 15 is not limited to the upper part inside the housing 10 as shown in the drawing,
The tray 20 and the sub-tray 4 loaded may be provided below the inside of the housing 10.
It may be any location where the presence or absence of the read-only disk 30 can be detected through the 0 windows 25 and 43. Further, the disc presence / absence detection may be performed by a pickup (not shown), and in this case, the disc presence / absence detection sensor 15 can be omitted.

Further, when the cartridge 50 is slotted in from the cartridge insertion opening 14 of the lid body 12, FIG.
As shown in FIG. 6, when the inner lid 13 is pushed up by the cartridge 50 and the insertion of the cartridge 50 is completed, the lower end portion of the inner lid 13 is placed on the upper surface of the rear end portion of the cartridge 50. There is.

At this time, the engagement pin 81 of the shutter opening member 80 waiting in the central portion of the housing 10 abuts on the taper portion 54 of the cartridge 50, and the pushing force of the cartridge 50 opens the shutter 52, and the cartridge 52 is opened. Windows 53 provided above and below 50 are opened.

When the insertion of the cartridge 50 is completed, the shutter 52 is completely opened, and the detection switch 44 provided in the inner part of the sub-tray 40 is turned on to rotate the servomechanical chassis 70. At the same time when the clamping operation is performed, the cartridge 50 is fixed on the tray 20 by a lock mechanism (not shown) provided on the servomechanical chassis 70.

On the other hand, when the cartridge 50 is ejected, the lock mechanism is unlocked as the servo mechanical chassis 70 is rotated downward by the operation of the eject switch 16, and thereafter the coil spring 8 is released.
The cartridge 50 is pushed out to the outside of the housing 10 by the restoring force of the shutter opening member 80 toward the arrow a side by 3. At this time, the lower end of the inner lid 13 is the cartridge 5
Since it is taken on the upper surface of the rear end of 0,
Not only does the inner lid 13 prevent the ejection of the cartridge 50, but since both sides of the inner lid 13 are guided by the side walls 21 of the tray 20 when the cartridge 50 is ejected, the cartridge 50 can be pushed out smoothly.

FIG. 9 shows a control system of the disk drive device. When the eject switch 16 is operated, the loading / eject determination section 91 determines the content of the operation instruction by the eject switch 16.

That is, when the tray 20 is housed inside the housing 10 (closed), the eject switch 16
Is operated, it is determined that the operation instruction content is eject, and when the eject switch 16 is operated while the tray 20 is being pushed out of the housing 10 (open), the operation instruction content is determined as loading. To be done. As a result, the eject switch 16 has an eject / loading function.

The control unit 90 controls the loading motor 1 via the driver 93 based on the result of the ejection / loading determination by the loading / eject determination unit 91.
7 is driven, and the tray 20 is pulled in or ejected. Here, the loading motor 17 not only provides driving force for retracting and ejecting the tray 20, but also rotational force for the servomechanical chassis 70.
Switching of these driving forces is performed by a switching mechanism (not shown).

When the detection switch 44 is turned on by the slot-in loading of the cartridge 50, the controller 90 drives the loading motor 17 to rotate the servomechanical chassis 70 to perform the clamp operation.

Further, when the tray presence / absence detection sensor 15 detects the read-only disc 30 in the tray 20 when the tray 20 is completely pulled in, the controller 9
0 rotates the servomechanical chassis 70 to perform the clamping operation, but when the read-only disk 30 is not detected, the control unit 90 does not rotate the servomechanical chassis 70 and the clamper 60 The state where the turntable 72 is separated is taken.

Next, the operation of the above disk drive device will be described. First, as shown in FIG. 1, when the tray 20 is opened, the eject switch 16 is operated and the loading motor 17 is driven to pull out the tray 20 from the opening 11 of the housing 10. At this time, as shown in FIG.
By pressing 2 from the inner side, the lid body 12 falls downward to the outer side against the biasing force of the elastic member (not shown).
The tray 20 can be pulled out smoothly.

Then, when the eject switch 16 is operated after the read-only disc 30 is accommodated in the accommodating holding groove 41 of the sub-tray 40 of the tray 20 that has been pulled out, the tray 20 is retracted into the housing 10. At this time, when the disc presence detection sensor 15 detects the read-only disc 30 in the tray 20, the servomechanical chassis 70 rotates and turns as shown in FIG. The table 72 comes into contact with the central portion of the read-only disc 30 and slightly lifts the read-only disc 30 from the sub-tray 40.

At this time, the centering hub 72a of the turntable 72 is fitted into the center hole of the read-only disc 30 to center the read-only disc 30. In addition, substantially at the same time when the read-only disc 30 is placed on the turntable 72, the rear end portion of the clamp arm 61 is pushed up by the push-up member 74, and the clamper 60 is placed on the central portion of the read-only disc 30 from the upper surface side. Abut.

Then, the central portion of the read-only disc 30 is sandwiched between the turntable 72 and the magnet (not shown) of the clamper 60 and the metal plate on the turntable 72 side, and the clamping operation is completed.
At this time, the clamper 60 is attached to the tip of the clamp arm 61.
Is loosely fitted and supported, the clamper 60 is freed from the tip of the clamp arm 61 by attracting the magnet and the metal plate, so that the read-only disk 30 rotates smoothly.

At approximately the same time as this clamping operation, the shutter release member 80 is pushed up by the push-up member 75, and the engagement pin 81 is released to a position where it does not hinder the rotation of the read-only disc 30.

When the spindle motor 71 is driven, the read-only disc 30 is rotated by the rotation of the turntable 72, and information is reproduced by a pickup (not shown).

On the other hand, when ejecting the read-only disk 30, when the eject switch 16 is operated, the servomechanical chassis 70 rotates downward. At approximately the same time, as the push-up member 74 moves away from the rear end of the clamp arm 61, the clamp arm 61 rotates in the clamp release direction by the urging force of an elastic member (not shown).

As described above, the clamper 60 and the turntable 72 are moved in the directions away from each other, so that the suction state between the clamper 60 and the turntable 72 is released, and the read-only disc 30 is returned to the sub-tray 40 and clamped. It will be canceled. Then, when the clamp is released, the tray 20 is pushed out from the opening 11 of the housing 10, and the ejecting operation is completed.

Next, the slot-in operation of the cartridge 50 accommodating the rewritable disc 51 will be described with reference to FIG. First, the ejected read-only disc 30 is taken out from the sub-tray 40 of the tray 20, the eject switch 16 is operated, and the tray 20 is returned to the inside of the housing 10. At this time, when the disk presence / absence detection sensor 15 detects the absence of the disk, the servomechanical chassis 70 is not rotated, and the clamper 60 and the turntable 72 are separated from each other as shown in FIG.

In this state, when the cartridge 50 is inserted into the cartridge insertion opening 14 of the lid 12, the cartridge 50 is pushed into the housing 10 while pushing up the inner lid 13. At this time, the edge of the cartridge 50 contacts the taper portion 45 provided on the front side of the sub-tray 40,
If the cartridge 50 is pushed in as it is, the sub tray 4
The cartridge 50 is housed in the tray 20 with 0 being lowered against the biasing force of the elastic member. When the cartridge 50 is mounted on the sub-tray 40, the cartridge 50 keeps the sub-tray 40 in the lowered state, so that the accommodation space of the cartridge 50 in the tray 20 is secured. Further, at this time, the cartridge 50 is pushed in while being guided by the side wall 21 of the tray 20, so that the pushing is smoothly performed.

When the cartridge 50 is pushed in by about half, the engagement pin 81 of the shutter opening member 80 waiting in the central portion of the housing 10 abuts the taper portion 54 of the cartridge 50, and the cartridge 50 is pushed in as it is. Therefore, the shutter 5 is pushed by the pushing force.
2 is opened, and the windows 53 provided above and below the cartridge 50 are opened.

When the insertion of the cartridge 50 is completed, the shutter 52 is completely opened, and the detection switch 44 provided in the inner part of the sub-tray 40 is turned on to perform the clamping operation by the rotation of the servomechanical chassis 70. At the same time, the servo mechanism chassis 70
The cartridge 50 is fixed onto the tray 20 by a lock mechanism (not shown) provided on the tray 20.

Further, as the servomechanical chassis 70 rotates, the turntable 72 enters through the window 53 below the cartridge 50, abuts on the central portion of the rewritable disc 51, and slightly moves to a substantially intermediate position in the cartridge 50. lift.

At this time, the centering hub 72a of the turntable 72 is fitted into the center hole of the rewritable disc 51 to center the rewritable disc 51. The rewritable disc 5 is placed on the turntable 72.
When the clamp arm 6 is loaded, the rear end portion of the clamp arm 61 is pushed up by the push-up member 74 almost at the same time.
When 0 touches the center of the rewritable disc 51 from the upper surface side, the clamper 60 and the turntable 72 are attracted to each other, and the center of the rewritable disc 51 is sandwiched between the turntable 72 and the rewritable disc 51. The clamp operation is completed. In this state, as described above, the clamper 60 is freed from the tip end portion of the clamp arm 61, so that the rewritable disc 51 rotates smoothly.

The push-up member 75 rises at substantially the same time as this clamping operation. However, as shown in FIG. 6, the shutter release member 80 is rotated to the arrow b side, and therefore the push-up member 75 is pushed. The push-up operation of the shutter opening member 80 by 75 is not performed.

When the spindle motor 71 is driven, the rewritable disc 51 is rotated by the rotation of the turntable 72, and information is reproduced by a pickup (not shown).

On the other hand, when ejecting the cartridge 50, when the eject switch 16 is operated, the servomechanical chassis 70 rotates downward, and the lock by the lock mechanism is released. At approximately the same time, the lifting member 74
As is separated from the rear end of the clamp arm 61, the clamp arm 61 rotates in the clamp releasing direction by the urging force of an elastic member (not shown). Then, when the clamper 60 and the turntable 72 move in a direction away from each other, the suction state between the clamper 60 and the turntable 72 is released, and the clamp operation is released.

Almost at the same time when the clamping operation is released, the cartridge 50 is pushed out of the housing 10 by the restoring force of the shutter opening member 80 toward the arrow a side by the coil spring 83. At this time, since the lower end portion of the inner lid 13 is set on the upper surface of the rear end portion of the cartridge 50, not only the inner lid 13 does not prevent the ejection of the cartridge 50, but also the both ends of the cartridge 50 are ejected. Since the side is guided by the side wall 21 of the tray 20, the cartridge 50 is smoothly pushed out.

As described above, the tray 20 is used in this embodiment.
When the read-only disk 30 as a single disk in the tray 20 is detected by the disk presence / absence detection sensor 15 as the disk presence / absence detection means after the completion of the drawing of the disk, the servomechanical chassis 70 is interlocked and clamped. The arm 61 is rotated to clamp the central portion of the read-only disc 30 between the turntable 72 and the clamper 60, and after the tray 20 has been pulled in, the read-only disc 30 in the tray 20 is moved by the disc presence / absence detection sensor 15. If not detected, the state where the clamper 60 and the turntable 72 are separated from each other is maintained, and the slot-in of the cartridge 50 from the opening 11 of the housing 10 is detected by the detection switch 44 as the cartridge detection means. Slot 50 of the cartridge 50 After the completion, the rewritable disc 51 as the disc in the cartridge 50 is clamped by the rotation of the servomechanical chassis 70 and the rotation of the clamp arm 61 interlocked therewith, so that tray loading and slot-in loading are performed. It can be compatible.

The lid 12 that closes the opening 11 of the housing 10 is rotatable to the outside of the housing 10, and the inner lid 13 that closes the cartridge insertion opening 14 provided in the housing 12 is also fitted. Since the cartridge 50 is rotatable inside the body, when the cartridge 50 is slotted in, it is only necessary to insert the cartridge 50 into the cartridge insertion port 14, and therefore the time required to carry the tray 20 can be omitted.

Furthermore, when the cartridge 50 is slot-in, the side wall 21 of the tray 20 guides the insertion, so that the cartridge 50 can be easily and individually slotted.

Further, after the tray 20 is completely drawn in,
When the read-only disk 30 in the tray 20 is detected by the disk presence / absence detection sensor 15, the rotation of the read-only disk 30 clamped by the shutter opening member 80 is not prevented in synchronization with the rotation of the servomechanical chassis 70. When the tray 20 is inside the housing 10, the shutter opening member 80 is set to the standby position at the home position when the tray 20 is inside the housing 10. Therefore, even if the tray 20 is housed inside the housing 10, the cartridge is opened. It is possible to surely open the shutter due to slot-in of 50, and it is possible to achieve both tray loading and slot-in loading.

After the slot 50 of the cartridge 50 is completed, the cartridge 50 is fixed to the clamp position by a lock mechanism (not shown) as the servomechanical chassis 70 rotates, and the servomechanical chassis 70 reversely rotates at the time of ejection. Accordingly, the lock by the lock mechanism is released and the restoring force of the shutter opening member 80 pushes the cartridge 50 to the outside of the housing 10. Therefore, both tray loading and slot-in loading can be achieved.

Therefore, even when the tray loading and the slot-in loading are both compatible, when the cartridge 50 is slot-in, it suffices to simply insert the cartridge 50 into the cartridge insertion port 14, so that the tray 20 can be carried for a long time. Since the rewritable disc 51 housed in the cartridge 50 is clamped, the time required to clamp the rewritable disc 51 is shortened.

As described above, according to the disk drive apparatus of the present invention, when the disk presence / absence detecting means detects the single disk in the tray after the completion of the drawing of the tray, the servomechanical chassis The clamp arm is rotated in conjunction with the rotation to clamp the central part of the disk unit between the turntable and the clamper, and after the tray is completely drawn in, the disk presence / absence detection unit detects the disk unit in the tray. If not, the state where the clamper and the turntable are separated from each other is maintained, and when the cartridge slot-in from the opening of the housing is detected by the cartridge detecting means, after the slot-in of the cartridge is completed, the servomechanical chassis Rotation of the clamp arm and rotation of the clamp arm Tsu Since so as to clamp the disk in di-, and a tray loading and slot-in loading can be compatible.

Further, the lid for closing the opening of the housing is rotatable to the outside of the housing, and the inner lid for closing the cartridge insertion port provided on the lid is rotatable to the inside of the housing. Therefore, when the cartridge is slotted in, it is sufficient to simply insert the cartridge into the cartridge insertion port, and the time required for carrying by the tray can be saved.

Further, when the cartridge is slot-in, the side wall of the tray guides the insertion, so that the slot-in of the cartridge can be performed easily and surely.

Furthermore, after the completion of pulling in the tray, when the disk presence / absence detecting means detects the single disk in the tray, the single disk with the shutter opening member clamped is synchronized with the rotation of the servomechanical chassis. When the tray is inside the housing, the shutter opening member is set to the standby position so that it does not interfere with the rotation, so the shutter opening member is placed in the standby position. Since it is possible to surely perform the shutter opening associated with the slot-in, it is possible to achieve both tray loading and slot-in loading.

Further, after the completion of slot insertion of the cartridge, the cartridge is fixed to the clamp position by the lock mechanism as the servomechanical chassis rotates, and at the time of ejection, the cartridge is locked by the reverse rotation of the servomechanical chassis. Since the lock is released and the cartridge is pushed out to the outside of the housing by the restoring force of the shutter opening member, both tray loading and slot-in loading can be achieved.

Therefore, even when both tray loading and slot-in loading are compatible, when the cartridge is slot-in, it is only necessary to insert the cartridge insertion port into the cartridge insertion port, and therefore the tray transfer time is omitted. Therefore, it is possible to shorten the time until the disc contained in the cartridge is clamped.
