-RAM, especially in the case of DVD-RAM, it is necessary to protect the recording surface in order to guarantee repeated recording a predetermined number of times (for example, 1 million times), so it is stored in a cartridge. Has become.

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 / holding groove 41 for accommodating and holding the read-only disc 30, and one end thereof. Four
The 0a 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 shutters 52 that close the windows 53 provided at the top and bottom, and when the cartridge 50 is loaded on the tray 20, it is held by the front wall 21a and the side wall 21. It has become. 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 inside the housing 10 as shown in FIGS. 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.

After the pull-in is completed, the clamp arm 61 rotates downward and the clamper 60 contacts the upper surface of the central portion of the read-only disc 30 in synchronization with this, as shown in FIG. Then, the servomechanical chassis 70 is rotated upward, and the turntable 72 is brought into contact with the lower surface of the central portion of the read-only disc 30, whereby the clamping operation is completed. 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. 16 (a) and 16 (b). The shutter opening member 80 is pushed by the peripheral portion and is pushed out to a position where it does not hinder the disc loading.

When the disc is ejected, the servomechanical chassis 70 is rotated downward, and then the clamp arm 61 is rotated upward to release the clamp, and the tray 20 is moved inside the housing 10. Is pushed out from.

On the other hand, when loading the cartridge 50 containing the rewritable disc 51, if the cartridge 50 is placed in the tray 20, FIG.
The tray 20 is pulled into the inside of the housing 10 as in (c). At this time, as shown in FIGS. 17A and 17B, 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. . Then, as described above, the clamp arm 61 and the servomechanical chassis 70 are
The rewritable disc 51 in the cartridge 50 is clamped by the rotation of, and information is reproduced or recorded.

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 view of the above circumstances, and provides a disk drive device capable of slot-inserting a disk alone and a disk housed in a cartridge from a common opening. And

The roller 93 is for pulling in (loading) the cartridge 50 containing the read-only discs 30 and 30a and the rewritable disc 51, which will be described later, into the housing 10. When the cartridge 30a and the cartridge 50 are inserted through the opening 11, a detection switch (not shown) provided in the vicinity of the opening 11 is turned on, and the driving force of a loading motor (not shown) causes the roller 93 to rotate.

Also, these read-only disks 30, 3
0a and the cartridge 50 are ejected,
When an eject switch (not shown) provided on the front surface of the housing 10 is operated, the rollers 93 rotate in the reverse direction so that the read-only disks 30, 30a and the cartridge 50 are pushed out (unloaded) from the inside of the housing 10. ing.

A pressing member 100 is provided above the roller 93. The pressing member 100 is composed of a pressing piece portion 102 that is rotatable about a rotating shaft 101 as a fulcrum, and a pressing piece portion 104 that is rotatable about the rotating shaft 103 with respect to the pressing piece portion 102. At the same time, the pressing pieces 102 and 104 are urged downward by an elastic member (not shown).

Then, the read-only disks 30, 30a
When the insert is inserted through the opening 11, these pressing pieces 10
2, 104 are slightly pushed up by the thickness of the read-only discs 30 and 30a, but the lower surface side of the read-only discs 30 and 30a is pressed against the roller 93 side by the urging force of an elastic member (not shown), so the loading by the roller 93 is prevented. It is surely done.

On the other hand, when the cartridge 50 is inserted from the opening 11, the pressing pieces 102 and 104 are pushed up by the thickness of the cartridge 50, but the lower surface side of the cartridge 50 is pressed against the roller 93 side in the same manner as above. The loading by the rollers 93 is ensured.

Further, each read-only disk 30, 30a
Is in the play position (which is also a clamp position), the pressing pieces 102, 104 are pushed upward by the movement of an interlocking slide plate (not shown) described later, so that the rotation of the read-only disks 30, 30a is not disturbed. It has become. However, cartridge 5
When 0 is in the play position, it is pushed up by the movement of the interlocking slide plate (not shown) in the same manner as above, but in this state, the pressing pieces 102, 104 are in elastic contact with the upper surface side of the cartridge 50, At the time of clamping, an engaging pin (not shown) provided on the servomechanical chassis 70 is engaged with an engaging hole provided on the lower surface side of the cartridge 50, so that rattling of the cartridge 50 can be suppressed. ing.

The height position of the pressing member 100 is regulated by a cam (not shown) that regulates the movement of the interlocking slide plate. Furthermore, when the read-only discs 30 and 30a and the cartridge 50 are ejected, the pushing force to the holding member 100 is released by the movement of the interlocking slide plate in the eject direction, and the urging force of the elastic member (not shown) is released. The pressing member 100 urged downward by the read-only disks 30, 3
By pressing the cartridge 0a and the cartridge 50 against the roller 93 side, the unloading by the roller 93 is surely performed.

Further, since the pressing piece portion 102 of the pressing member 100 is inclined downward and has a tapered shape together with the tapered surface 91 of the support member 90, the read-only disks 30, 30a are formed by this tapered shape. Also, the cartridge 50 can be easily and surely inserted.

Above the pressing member 100, a lock member 110 is provided which is rotatable about a shaft 111 as a fulcrum and is urged in a locking direction (arrow direction in the drawing) by an elastic member (not shown). Has been done. The lock member 110 is provided with lock piece portions 113 and 114 at different positions along the loading direction, and when a lock piece portion 121 of a centering plate 120, which will be described later, is locked, the centering plate 120 of the centering plate 120 is locked. Movement in the loading direction is restricted. That is, a read-only disc 30 having a size of 8 cm described later.
When a is loaded, the locking piece 121 is locked to the lock piece 113, and when the 12 cm size read-only disc 30 described below is loaded, the locking piece 121 is locked to the lock piece 114. As a result, the center of the play position of these read-only disks 30, 30a is positioned.

However, when the cartridge 50 is loaded, the locking piece 121 is used to determine which lock piece 1
Centering plate 1 without being locked by 13, 114
20 can be pushed to the innermost part of the housing 10.

On the lower surface side of the lock member 110, the contact piece 1 that contacts the outer peripheral edge of the read-only disk 30 or the cartridge 50 during loading and unloading.
12 are provided. The contact piece 112 is for pushing out the lock member 110 in the unlocking direction (the direction opposite to the arrow direction in the drawing). That is, when the read-only disc 30 is loaded, the outer peripheral edge portion thereof contacts the contact piece 112, and the maximum outer peripheral edge portion (the outer peripheral edge portion in the disk radial direction orthogonal to the loading direction) of the contact piece 112. When the lock member 110 comes into contact with 112, the rotation amount of the lock member 110 becomes maximum, and when the lock member 110 exceeds the maximum outer peripheral edge portion, the lock member 110 is returned in the lock direction by an elastic member (not shown). This means that even when the read-only disc 30 is ejected,
0 performs the same rotation operation.

On the other hand, when the cartridge 50 is loaded, the linear side surface, which is the outer peripheral edge of the cartridge 50, abuts the abutment piece 112, so that the lock member 110 is unlocked (in the direction indicated by the arrow in the figure). Is the opposite)
The state of being pushed out is maintained, and the state is maintained even when the cartridge 50 is ejected.

However, in the case of the read-only disc 30a having a size of 8 cm, since the diameter is small, loading is performed without contacting the contact piece 112. Lock member 1
In the vicinity of 10, a centering plate 120 that is movable in the loading / ejecting direction, which is the arrow direction, and is biased in the ejecting direction by an elastic member (not shown) is arranged. The centering plate 120 is for positioning the center of the loaded read-only discs 30 and 30a in the play position, and has a centering groove 122 for centering the read-only disc 30 having a size of 12 cm described later and an 8 cm described later. A centering groove 123 is provided for centering the read-only disk 30a of a size. The centering grooves 122 and 123 have a curved shape that matches the shape of each disk.

On the upper surface of the end portion of the centering plate 120, there is provided a locking piece portion 121 which is locked to the lock piece portions 113 and 114, and when the read-only disk 30a of 8 cm size is centered, The locking piece 121 is locked by the lock piece 113, and is 12 cm.
When the read-only disk 30 of a size is centered, the locking piece 121 is locked by the locking piece 114. Further, in the vicinity of the locking piece 121 of the centering plate 120, a concave groove 125 into which a lower end 155 of a shutter opening member 152 described later is fitted.
Is provided.

Below the centering plate 120,
The shaft 132 is rotatable around a fulcrum, and an L-shaped groove 141 of a slide plate 140, which will be described later, is provided at the other end.
Interlocking lever 130 having an engagement pin 133 that is engaged with
Is provided. Then, the read-only disk 30,
When the disk 30a is loaded, the outer peripheral edge portions of the read-only disks 30 and 30a come into contact with the engaging pin 131 of the interlocking lever 130, so that the interlocking lever 130 is loaded.
Is slightly rotated, and the engagement pin 133 moves the slide plate 1
40 is slightly moved in the loading direction. Also, when the cartridge 50 is loaded, the slide plate 140 is slightly moved in the loading direction, which will be described in detail later.

Above the interlocking lever 130, the support arm 1 is rotatable about a shaft 151 as a fulcrum and is urged in the eject direction by an elastic member (not shown).
50 are provided. The U-shaped groove 156 provided at the end of the support arm 150 has a shutter opening member 1
52 is rotatably fitted around the shaft 154 as a fulcrum. An engaging pin 153 for opening a shutter 52 of the cartridge 50, which will be described later, is hung at the tip of the shutter opening member 152.
When is not loaded, the engaging pin 153 is biased to the upper position by an elastic member (not shown), and the operation of the shutter opening member 152 will be described later.

Below the shutter opening member 152, the slide plate 140 having the above-mentioned L-shaped groove 141.
Are arranged so as to be slightly movable in the loading / ejecting direction. The L-shaped groove 141 has a vertical groove 14
1a and a lateral groove 141b are provided, and the interlocking lever 1 is provided when the read-only disks 30 and 30a are loaded.
The engaging pin 133 of 30 is located on the vertical groove 141a side, and when the cartridge 50 is loaded, the engaging pin 133 is located on the lateral groove 141b side to slightly move the slide plate 140 in the loading direction.

The slide plate 140 moves an interlocking slide plate which moves up and down with respect to the pressing member 100 and rotates a servo mechanical chassis (not shown) by the driving force of a single loading motor (not shown). It is for making it. Then, when the interlocking slide plate is slightly moved in the loading direction by the engaging protrusion 142 of the slide plate 140, the interlocking slide plate is moved in the loading direction by receiving the driving force of the loading motor, and at the same time, the above-mentioned presser foot is held at the predetermined position. A predetermined operation is interlocked with the member 100 or a servomechanical chassis (not shown).

Incidentally, the servomechanical chassis (not shown) is arranged on the lowermost side of the casing 10, and the clamp arm (not shown) is arranged on the uppermost side of the casing 10. Next, the operation of the disk drive device having the above configuration will be described. First, the case where the read-only disk 30 of 12 cm size is slot-in is shown in FIG.
It will be described with reference to FIGS.

That is, as shown in FIGS. 3 and 5, when the read-only disk 30 is slightly inserted through the opening 11 of the housing 10, the detection switch (not shown) detects the insertion of the read-only disk 30, and the read-only disk 30 is not shown. The read-only disc 30 is drawn into the housing 10 by the roller 93 that is rotated by the driving of the loading motor.

At this time, the tapered surface 91 of the support member 90 disposed near the opening 11 and the pressing piece 102 of the pressing member 100 that is inclined downward form a tapered shape. Even when the read-only disc 30 is roughly inserted through the opening 11, the outer peripheral edge of the read-only disc 30 is easily and surely pushed into the roller 93 side.

At this time, the pressing pieces 102 and 104 of the pressing member 100 are slightly pushed up by the urging force of the elastic member (not shown) by the thickness of the read-only disc 30, but due to the restoring force, the lower surface of the read-only disc 30. Since the side is pressed against the roller 93 side, the roller 9
The loading by 3 is reliably performed.

When the read-only disc 30 is pulled in, the outer peripheral edge portion thereof contacts the centering groove 122, and the centering plate 120 is gradually pushed in as the read-only disc 30 is loaded.

When the outer peripheral edge of the read-only disk 30 contacts the contact piece 112 of the lock member 110, the lock member 110 resists the urging force of the elastic member in the unlocking direction (the arrow direction in the figure). When the maximum outer peripheral edge portion (outer peripheral edge portion in the disc radial direction orthogonal to the loading direction) is in contact with the contact piece 112, the lock piece portion 113 is pushed out of the locking piece portion 121. Since it deviates from the movement trajectory, the centering plate 120 is further pushed in as the read-only disc 30 is pulled in without the locking piece 121 being locked by the lock piece 113.

When the abutting position of the abutting piece 112 exceeds the maximum outer peripheral edge portion, the locking member 110 gradually returns in the locking direction by the urging force of the elastic member, and the locking piece portion 114 of the locking piece portion 121. It is returned to the movement track.

When the centering plate 120 is pushed further, the locking piece 121 is locked.
And the pushing of the centering plate 120 is restricted. As a result, the pulling-in of the read-only disc 30 is prevented by the movement of the centering plate 120 abutted against the centering groove 122, and the center of the read-only disc 30 is positioned in the pre-positioning.

At this time, as the centering plate 120 moves, the lower end portion 15 of the shutter opening member 152 is moved.
The shutter opening member 152 rotates by engaging the groove 5 with the recessed groove 125 by the urging force of the elastic member after the rider 5 rides on the upper surface side of the centering plate 120, and the engagement pin 153 at the tip of the shutter opening member 152 rotates the read-only disc 30. Away from the top side of.

At this time, the centering plate 12
With the movement of 0, the shaft 132 side of the interlocking lever 130 is moved in the loading direction, the engaging pin 133 of the interlocking lever 130 is pushed into the vertical groove 141a side of the L-shaped groove 141, and the engaging pin 131 of the interlocking lever 130 is also moved. Is disengaged from the engaging groove 124 of the centering plate 120 and pops out toward the read-only disc 30. When the outer peripheral edge of the loaded read-only disc 30 comes into contact with the engagement pin 131, the interlocking lever 130 rotates clockwise about the shaft 132 as a fulcrum, and the engagement pin 133 moves along the vertical groove 1.
The slide plate 140 is slightly moved in the loading direction via 41a.

When the slide plate 140 slightly moves in the loading direction and the engaging protrusion 142 slightly moves the interlocking slide plate (not shown) in the loading direction, the interlocking slide plate receives the driving force of the loading motor (not shown) and the loading direction. Move to. Then, with the movement of the interlocking slide plate (not shown),
When the holding member 100 pressing the lower surface of the read-only disc 30 against the roller 93 is gradually pushed up and the read-only disc 30 reaches the play position, the holding member 100 is completely pushed from the upper surface side of the read-only disc 30. Be separated.

When the read-only disc 30 reaches the position immediately before reaching the play position, the interlocking slide plate gradually rotates the servomechanical chassis (not shown), and when the read-only disc 30 reaches the play position, the servo mechanism is rotated. A turntable (not shown) mounted on the chassis places the read-only disc 30 while centering the central portion of the read-only disc 30 from the lower surface side.

At this time, in synchronization with the rotation of the servomechanical chassis, the clamp arm which loosely fits and supports the clamper 160 is rotated, and the clamper 160 abuts on the upper surface side of the central portion thereof. And as shown in FIG.
The read-only disc 30 is clamped.

When the clamping of the read-only disk 30 is completed, the driving of the loading motor is stopped, and in synchronization with this, the spindle motor (not shown) mounted on the servomechanical chassis is driven, so that the read-only disk 30 is It is rotated and information is reproduced by a pickup (not shown).

On the other hand, in the case of ejecting the read-only disk 30, if the eject switch (not shown) provided on the front side of the housing 10 is operated, the drive of the spindle motor is stopped, and in synchronization with this, the above-mentioned operation is performed. The loading motor is driven and the interlocking slide plate is sent out in the eject direction. With the movement of the interlocking slide plate, the servomechanical chassis is first rotated in the opposite direction, and the clamp arm is rotated upward by the urging force of the elastic member (not shown), so that the clamper 160 and the turntable are separated from each other. Then, the read-only disk 30 is released from the clamp.

In synchronism with this, since the pushing force to the pressing member 100 by the interlocking slide plate is released, the pressing member 100 is lowered by the urging force of the elastic member (not shown), and the lower surface side of the read-only disc 30 is moved to the roller 93. When pressed, the read-only disc 30 is pushed out in the eject direction by the reverse rotation of the roller 93.

At this time, as the read-only disk 30 moves in the eject direction, the centering plate 120 moves in the eject direction by the urging force of an elastic member (not shown).
The side is returned in the same direction, and the engaging pin 131 of the interlocking lever 130 is fitted into the engaging groove 124, so that the engaging pin 133 of the interlocking lever 130 is inserted into the vertical groove 141 a and the lateral groove 1.
It is returned to the intersection with 41b.

Further, at this time, the read-only disk 3 is moved along with the movement of the read-only disk 30 in the eject direction.
When the outer peripheral edge portion of 0 presses the contact piece 112, the lock member 110 is gradually pushed out in the unlocking direction (the arrow direction in the figure) against the biasing force of the elastic member, and the maximum outer peripheral edge portion (loading In the state where the outer peripheral edge portion in the disc radial direction orthogonal to the direction) abuts on the abutment piece 112, the lock piece portion 113 deviates from the movement trajectory of the engagement piece portion 121, so that the ejecting direction of the centering plate 120 The movement to the is smoothly performed without being disturbed by the lock piece portion 113.

Further, at this time, when the interlocking slide plate is returned to the position (home position) before the loading is started, the slide plate 140 is slightly returned in the eject direction via the engaging projection 142.

Then, the read-only disc 30 is pushed out in the eject direction by the reverse rotation of the roller 93, whereby the ejection of the read-only disc 30 is completed. Next, the slot-in operation of the read-only disk 30a having a size of 8 cm will be described with reference to FIGS.

That is, as shown in FIG. 7, when the read-only disc 30a is slightly inserted from the opening 11 of the housing 10, the roller 93 is rotated by the detection by the detection switch, and the read-only disc 30a is opened. It is drawn into the housing 10.

At this time, even when the read-only disk 30 is roughly inserted from the opening 11, the taper surface 91 of the supporting member 90 and the pressing piece 102 of the pressing member 100.
Read-only disk 30a due to the tapered shape of
