[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium mounting device, and more particularly, to a recording medium mounting device configured to mount different types of recording media.

[0002]

2. Description of the Related Art As a conventional recording medium mounting apparatus, an example of a conventional apparatus mounted on a disk apparatus compatible with a plurality of types of disk recording media (hereinafter referred to as a compatible disk apparatus) will be described. explain.

For example, in an electronic device such as a personal computer or a word processor, a disk device is built in or externally provided as a means for reproducing and / or recording information. This disk device uses a disk-shaped recording medium as a recording medium. Also,
This disk-shaped recording medium is mounted inside the disk device using a recording medium mounting device, and is configured to perform reproduction and / or recording processing.

[0004] On the other hand, various types of disc-shaped recording media are provided, for example, CD (Compact Disc), C
DR (Compact Disc-Recordable), CD-ROM (Compa
ct Disc-Read Only Memory), CD-RW (Compact Disc)
-Rewritable), DVD-ROM (Digital Versatile Disc)
-Read Only Memory), DVD-RAM (Digital Versatil
e Disc-Random Access Memory) is known. These are disks with a diameter of 12 centimeters,
There are two types, 8 cm. Furthermore, DVD-RA
There are three types of M, in addition to a configuration in which a disk is mounted in a disk cartridge.

[0005] As described above, various types of disk-shaped recording media are provided, but it is convenient if each of these disk-shaped recording media can be reproduced and / or recorded by a single disk device. is there. For this reason, compatible disk devices that are compatible with the various disk-shaped recording media described above have been provided.

In this compatible disk device, it is necessary to convey a disk-shaped recording medium having a different form to the disk device main body. However, a conventional recording medium mounting device uses a tray as a means for conveying various disk-shaped recording media to the disk device main body. Was used.

The tray can be pulled out of the disk drive main body, and is drawn out of the disk drive main body when a disk-shaped recording medium is loaded and ejected (hereinafter, referred to as "eject"). . In addition, a mounting recess for mounting a 12 cm disk, an 8 cm disk, and a disk cartridge is formed on the disk mounting surface of the tray, so that various types of disk-shaped recording media having different forms can be mounted on the tray. It had been.

[0008]

The conventional compatible disk device has a tray for mounting various types of disk-shaped recording media having different forms as described above. Inevitably, the tray must be drawn out of the disk drive body. For this reason, in a conventional compatible disk device,
When installing the apparatus, it is necessary to set a space in advance in consideration of the drawer amount of the tray, and there is a problem that the installation space becomes large.

Further, as a recording medium mounting apparatus which solves this problem, a configuration is conceivable in which the outer peripheral position of the disk-shaped recording medium is clamped by a clamp lever and pulled into the disk apparatus body without using a tray. However, in the configuration using the clamp lever, it is necessary to stop the clamp lever at a plurality of locations in the apparatus.

That is, in the recording medium mounting apparatus using the tray, even when the disk-shaped recording mediums of different forms are mounted in the mounting recesses of the tray, the center position (clamped position) of each disk-shaped recording medium is determined. Will be the same. For this reason, in the recording medium mounting apparatus using the tray, it is not necessary to change the draw-in position of the tray according to the type of the disk-shaped recording medium.

However, in the configuration in which the disk-shaped recording medium is conveyed by the clamp lever, the clamp lever holds the outer periphery (for example, the leading end in the insertion direction) of the disk-shaped recording medium, so that the 8 cm disk is clamped to the turntable. The position of the clamp lever to be used is different from the position of the clamp lever that clamps the 12 cm disc to the turntable. Specifically, the position of the clamp lever for clamping the 12 cm disc to the turntable is located at a position farther in the insertion direction than the position of the clamp lever for clamping the 8 cm disc to the turntable. Similarly, the position at which the clamp lever clamps each disk and the position at which each disk is retracted so as not to hinder the rotation of the disk after mounting each disk on the turntable are different for each type of disk.

Therefore, when controlling the movement of the clamp lever, it is necessary to stop the clamp lever at each stop position set for each different disk as described above. As means for detecting the stop position of the clamp lever,
It is conceivable to use an inexpensive and highly reliable on / off switch. In this case, the stop position of the clamp lever is detected by disposing the on / off switch at a predetermined stop position of the clamp lever and pressing the on / off switch with the movement of the clamp lever. be able to.

In this case, when one kind of disk is transported by the clamp lever, even if the on / off switch is used, the stop position of the clamp lever is small (for example, three places). The number of ON / OFF switches to be performed can be reduced. However, in a compatible disk device capable of mounting a plurality of types of disks, the stop position of the clamp lever is increased.
That is, for example, in a compatible disk device configured to mount three types of disks, if each of the three types of disks has three stop positions, a total of nine on / off switches are required.

Therefore, when the stop position of the clamp lever is to be detected by the conventional method using only the on / off switch which has been conventionally performed, the number of required switches is increased, and the number of components of the recording medium mounting apparatus is reduced. There has been a problem that the configuration is complicated and the cost is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to provide a recording medium mounting apparatus capable of simplifying the configuration and reducing the cost.

[0016]

3, 74-4.

Here, the disposition position of the tongue piece 86 formed on the clip disk 74 will be described with reference to FIG. As described above, a pair of tongue pieces 86 are formed on each of the clip disks 74, but when the clip disk 74 is provided, one of the tongue pieces 8 is formed.
The position of the tongue piece 6 is set so as to face the curved wall 94 for the 8 cm disc (hereinafter, when the tongue piece 86 is specified and described, the tongue piece 86 is attached to the 8 cm disc tongue piece 86- 8). Also, the other tongue piece 86 is 12 cm
The disposition position is set so as to face the curved wall 95 for the disk (hereinafter, when the tongue portion 86 is specified and described, the tongue portion 86 is set to the 12 cm disk tongue portion 86.
-12).

Therefore, when the 8 cm disc 11 is inserted into the carrier unit 70, the 8 cm disc 11
Is held by an 8 cm disc tongue piece 86-8. When the 12 cm disc 12 is inserted into the carrier unit 70, the 12 cm disc 12 is held by the 12 cm disc tongue piece 86-12. Each of the disks 11, 12 is provided with a disk tongue piece 86-8, 86-1.
In the state of being held in the disk drive 2, each disk 11,
12 is transported between a position where insertion / removal is performed (hereinafter, this position is referred to as an ejection position) and a loading position.

At the time of this transfer, each of the disks 11 and 12
The disc is conveyed while its outer peripheral edge (specifically, the front edge in the insertion direction) is held by the disk tongue pieces 86-8 and 86-12. Specifically, an area in which recording / reproduction is not performed is formed in a predetermined range on the outer periphery of each of the disks 11 and 12, and the abutting portion 88 of each of the disk tongue pieces 86-8 and 86-12.
Is configured to contact an area where recording / reproduction is not performed. Therefore, it is possible to prevent the recording / reproducing processing areas on the surfaces of the discs 11 and 12 from being damaged during transportation.

Further, as described above, each disk tongue piece 8
6-8 and 86-12 perform the carrying process in a state where the disks 11 and 12 are clamped. Therefore, during the carrying process, the tongue pieces 86-8 and 86-12 and the disks 11 and 12 are used.
And no relative displacement (slip) occurs between them, and a highly accurate transfer process can be performed.

By the way, the operator of the disk device 10
When the discs 11 and 12 are held in a gripped state after the discs 11 and 12 are inserted and held by the carrier unit 70, a pulling force acts on the discs 11 and 12. When the operator performs such an erroneous operation, operability is reduced in a configuration in which the discs 11 and 12 are immediately separated from the carrier unit 70, and the clamping operation may fail. Therefore, even if a certain amount of pulling force acts on the disks 11 and 12 after insertion, the disks 11 and 12 are immediately
It is desirable to configure so as not to be separated from.

On the other hand, in the present embodiment, the tongue piece 86 provided on the clip disk 74 gradually approaches the insertion direction (the direction of the arrow Y1 in the drawing) as described above, and It is configured to contact the periphery.
For this reason, in the holding state shown in FIG. 7B, when a force (pulling force) is applied to the disks 11 and 12 in the direction of pulling out from the carrier unit 70, the pulling force causes the tongue piece 86 to have an arrow in the drawing. A force indicated by B is generated, and this force acts as a force for pressing the contact portion 88 against the disks 11 and 12. As a result, even after the discs 11 and 12 are held by the carrier unit 70 (clip disc 74) and the discs 11 and 12 are pulled out by mistake, the discs 11 and 12 are retained by the carrier unit 70.
(Clip disk 74) can be prevented from being detached.

In this embodiment, a pair of upper and lower clip disks (a first clip disk 74-1 and a second clip disk 74-2, a third clip disk 7
Although the discs 11 and 12 are clamped by the 4-3 and the fourth clip discs 74-4), as shown in FIG.
4, the disks 11 and 12 may be sandwiched. In this case, the number of clip disks can be reduced, and the space for arranging the clip disks is also reduced, which is advantageous in reducing the size of the carrier unit 70.

In this embodiment, the disk detection switches 96 and 97 are disposed on the disk curved walls 94 and 95, respectively. However, the positions at which the disk detection switches 96 and 97 are disposed may be set to positions facing the clip disk 74. FIG. 9 shows an example in which the disk detection switches 96 and 97 are arranged at positions facing the clip disk 74.

Each disk detection switch 96, 97
It has a contact portion 99 that is pressed by inserting the disks 11 and 12. The contact portion 99 is configured to be movable in the vertical direction in FIG. 9, and is urged upward by a spring (not shown) arranged in the switch body. Then, as shown in FIG. 9A, each of the disk detection switches 96 and 97 is
Is disposed so as to face the contact portion 88 of the clip disk 74.

Therefore, when the disks 11, 12 are inserted into the carrier unit 70, as shown in FIG.
The disks 11, 12 are held between the clip disk 74 and the disk detection switches 96, 97. Further, since the tongue piece 86 has a spring property and the contact part 99 is urged upward, the disc 1
The discs 1 and 12 are firmly held between the clip disc 74 and the disc detection switches 96 and 97. Therefore, with the configuration shown in FIG. 9, the disk detection switches 96 and 97 have a function equivalent to that of the second clip disk 74-2 disposed on the lower right half 72 in addition to the function as a switch. Therefore, the number of parts can be reduced, and the size of the carrier unit 70 can be reduced.

Here, returning to FIG. 1, the description will be continued. The carrier unit 70 having the above configuration is movably attached to the holder 40 as described above. This holder 4
The base cover 120 is disposed above the “0”. The base cover 120 is formed by pressing a metal plate, and includes a top plate 121, a right plate 122, and a left plate 123.

The first and second concave portions 1 are provided in the top plate 121.
24, 125 are formed, in particular the first recess 124
Is formed with the slit 126 described above. Also,
The right and left side plate portions 122 and 123 are formed with a shaft hole 127 that supports the rotation shaft 57 formed in the holder 40 (the left rotation shaft 57 and the shaft hole 127 do not appear in the drawing).
The base cover 120 having the above configuration is fixed to the base 20, so that the position of the base cover 120 with respect to the base 20 does not change. Further, as described above, the holder 40 is configured to swing between the base 20 and the base cover 120 (FIGS. 4A and 4B).

Further, a front bezel 130 is provided at the front of the disk drive 10 (see FIGS. 2 and 4). An insertion opening 133 is formed in the front bezel 130, and the disks 11, 12 and the disk cartridge 13 are inserted into and removed from the disk device 10 through the insertion opening 133.

The insertion opening 133 is provided with lids 131 and 132 that can be opened and closed by an opening and closing mechanism (not shown). The insertion openings 133 are closed by the lids 131 and 132 except when the disks 11 and 12 and the disk cartridge 13 are inserted and removed, thereby preventing dust from entering the disk device 10.

Next, the operation of the recording medium mounting apparatus having the above configuration will be described. As shown in FIG.
The control device 150 includes an 8 cm disk detection switch 96.
(Hereinafter abbreviated as 8-SW 96), 12-cm disk detection switch 97 (hereinafter abbreviated as 12-SW 97), disk cartridge detection switch 98 (hereinafter abbreviated as DC-SW 98), clapping Motor 68, loading motor 100, and SW1 to SW
3 are connected. Then, based on signals from the switches 96 to 98 and the switches SW1 to SW3, the driving of the clamping motor 68 and the loading motor 100 is controlled. At this time, control device 150 performs the control operation shown in FIGS. Hereinafter, a specific control operation performed by the control device 150 will be described.

When the control process shown in FIG. 23 is started, the control device 150 determines whether or not the 8-cm disc 11 has been inserted in the output signal of the 8-SW 96 in step 1 (the step is abbreviated as S in the figure). Judge based on. Then, when the 8-SW 96 is ON (that is, when it is determined that the 8-cm disc 11 is inserted), the processing shown in FIG. 24 is started. If the 8-SW 96 is off (that is, if it is determined that the 8-cm disc 11 is not inserted), the process proceeds to step 2.

In step 2, it is determined whether or not the 12 cm disk 12 has been inserted based on the output signal of the 12-SW 97. Then, when the 12-SW 97 is ON (that is, when it is determined that the 12 cm disc 12 has been inserted), the processing shown in FIG. 25 is started. Also, 12
If the SW 97 is off (that is, if it is determined that the 12 cm disc 12 has not been inserted), the process proceeds to step 3.

In step 3, the disk cartridge 1
3 is determined based on the output signal of the DC-SW 98. Then, when the DC-SW 98 is ON (that is, when it is determined that the disk cartridge 13 has been inserted), the processing shown in FIG. 26 is started. If the DC-SW 98 is off (that is, if it is determined that the disk cartridge 13 is not inserted), the process returns to step 1 again.

FIG. 2 shows a state in which a negative determination (determination of NO) is made in any of the steps 1 to 3.
Shown in This state is a state in which the disks 11, 12 and the disk cartridge 13 are not inserted, and more specifically, is a state shown in FIGS. 2 and 21A. At this time, the carrier unit 70 has moved to a position limited in the direction of arrow Y2 in the figure (hereinafter, this position is referred to as an eject position P1).

When the carrier unit 70 is at the ejection position P
1, SW1 is the first convex portion 1 of the upper cam portion 141.
SW2 is engaged with the convex portion 14 of the lower cam portion 142.
2a, and SW3 is in a state of facing the first concave portion 141b of the upper cam portion 141. Therefore, SW1
The on / off state of SW3 is [SW1, SW2, SW
3] = [ON, ON, OFF].

In the following description, SW1 to SW3
The on / off state of is described in brackets as described above and shown as [on, on, off]. At this time, the left side of the brackets is the state of SW1, the middle is the state of SW2, and the right side is the state of SW3.

Further, as described above, the carrier unit 70
Is in the eject position P1, the lever main body 61 of the disc lever 60 moves as shown in FIG.
The carrier unit 70 is in contact with a stepped cam portion N1 formed on the back surface of the carrier unit 70 (details will be described later). As a result, the disc lever 60 resists the urging force of the disc lever urging spring 65, and the carrier unit 70
Has retreated to a position where it does not interfere with the movement of Also,
When the shaft 105 moves in the cartridge lever guide grooves 103 and 104 as described above, the cartridge lever 77 moves to the arrow Y in FIG.
The configuration is such that it can be displaced in the 1 and 2 directions. Further, the cartridge lever 77 is urged to move in the direction of arrow Y2 in the figure by a cartridge lever urging spring 108.

However, when the carrier unit 70 is at the eject position P1, the engaging claw 106 formed on the cartridge lever 77 is configured to engage with the cartridge lever retreat cam 54 provided on the right rail 50. ing. When the carrier unit 70 has moved to the ejection position P1, the shaft 105 is positioned in the direction indicated by the arrow Y1 of the cartridge lever guide grooves 103 and 104 in the drawing.
It is configured to be located in the direction limit.

The cartridge retreat cam 54 has an inclined surface, and the engaging claw 106 of the cartridge lever 77 is configured to engage with the inclined surface.
Therefore, when the cartridge lever 77 is pressed against the inclined surface, the engaging claw 106 is pushed by the cartridge lever urging spring 108.
Is displaced along the inclined surface against the elastic force of the cartridge lever 77, whereby the cartridge lever 77 rotates a little counterclockwise about the shaft 105.

However, a cover N2 (partially shown in FIG. 2) of the disk device is provided outside the cartridge lever 77 (in the direction of the arrow X2 in the figure). Therefore, when the outer side surface of the cartridge lever 77 comes into contact with the cover N2, further rotation of the cartridge lever 77 in the counterclockwise direction is restricted.

Here, pay attention to the position of the cartridge lever 77 with respect to the carrier unit 70 when the carrier unit 70 is at the eject position P1. As described above, the carrier unit 70 is positioned at the ejection position P.
When the cartridge lever 77 comes in contact with the cartridge lever retraction cam 54 and the cover N2, the shaft portion 105 moves the cartridge lever guide groove 103, 1
04 has been moved to the limit in the direction of the arrow Y1 in the figure.

Accordingly, the cartridge lever 77 is also displaced with respect to the carrier unit 70 in the direction of arrow Y1 in the figure. Therefore, even when the carrier unit 70 is located at the eject position P1, the cartridge lever 77 does not project from the front surface 89 of the carrier unit 70 in the direction of the arrow Y2 in the figure.

In a conventional disk device using a tray,
In the eject state, the tray extends forward from the apparatus main body, causing an increase in installation space and damage to the tray. However, in the disk device 10 according to the present embodiment, even when the disk device 10 is in the ejected state, there is nothing protruding in front of the disk device 10. Can be suppressed.

On the other hand, the shutter lever 78 is at a position clockwise rotated by being guided by a slit 126 (not shown in FIG. 2) formed in the base cover 120. In this state, the shutter driving pin 113
Is configured to be located at an engagement position for engaging with a shutter 15 formed on the disk cartridge 13 to be inserted.

Further, when the carrier unit 70 is at the ejection position P1, the holder 40 has been moved to the upward movement position as shown in FIG. 4 (A). Holder 40
Is in the upward movement position, the carrier unit 70 is in a state of facing the insertion opening 133 of the front bezel 130, and the disks 11, 12 and the disk cartridge 1
3 is allowed.

When the 8 cm disk 11 is inserted into the ejected disk device 10 shown in FIG. 2 via the front bezel 130, the 8 cm disk 11 is guided by the disk facing surface 93 as described above, and It advances in the Y1 direction, and eventually comes into contact with the 8 cm disk curved wall 94, and is held together with the 8 cm disk tongue piece 86-8 (clip disk 74). When the 8 cm disk 11 comes into contact with the 8 cm disk curved wall 94, the 8 cm disk detection switch 96 is pressed by the 8 cm disk 11. Thereby, control device 150 detects that 8 cm disk 11 is held in carrier unit 70. Accordingly, an affirmative determination is made in step 1, and the control device 150
The control process shown in FIG. Also, 8cm disc 1
With the insertion of 1, the carrier unit 70 moves in the direction of arrow Y1 in FIG. Therefore, SW1 to S
The switch state of W3 is [OFF, ON, OFF].

At step 10, the control device 150 starts applying a voltage to the loading motor 100, whereby the gear 102 is rotated via the gear group 101. At this time, the control device keeps moving the carrier unit 70 from the position shown in FIG.
The driving voltage applied to the loading motor 100 is about 20% of the normal driving voltage (E volt) (0.2%).

More specifically, the carrier unit 70 shown in FIG.
During the movement from the eject position P1 shown in FIG. 12 to the position shown in FIG. 12, a voltage (0.2 × E) of about 20% of the normal drive voltage (E) is applied to the loading motor 100. In the following description, the position of the carrier unit 70 shown in FIG. 12 is referred to as an 8 cm disk loading start position (abbreviated as 8L start position).
It is assumed that

When the voltage applied to the loading motor 100 is reduced as described above,
Since the driving force at which 0 is generated also decreases, the carrier unit 70 does not move in this state. However,
When the disc is inserted, the insertion force for the operator to insert the 8 cm disc 11 into the disc device 10 is applied to the carrier unit 7.
0 is applied. Thereby, the carrier unit 70 starts moving in the direction of arrow Y1 in the figure.

Therefore, when the operator inserts the 8 cm disc 11 to the first loading start position P2, the driving force of the loading motor 100 assists the insertion force of the operator. For this reason, the operator can insert the 8 cm disc 11 with a small insertion force,
Therefore, the operability at the time of inserting the 8 cm disk 11 can be improved.

The control device 150 constantly monitors whether the 8-SW 96 is turned off during the loading motor assist state (step 1).
1). Then, in step 11, an affirmative judgment (ie,
If it is determined that the 8-SW 96 is off, the process proceeds to step 12 and the control device 150
Drive 0 in the reverse loading direction. As a result, the carrier unit 70 returns to the eject position P1 again.

Here, if an affirmative determination is made in step 11, for example, the operator notices immediately after the insertion that the 8 cm disc mounted by the operator has mistakenly inserted a disc-shaped recording medium different from the 8 cm disc to be mounted, This is the case where the erroneously inserted 8 cm disc is pulled out. In the present embodiment, in the loading motor assist state performed in step 10, when the operator releases the insertion force, the movement of the carrier unit 70 stops, so that the 8 cm disk being conveyed can be pulled out as described above. is there. As a result, the operator can replace the 8 cm disc when he or she notices an erroneous insertion, without having to wait for the loading of the 8 cm disc once at the loading position as in the related art, thereby improving the usability. Can be planned. If it is determined in step 11 that the 8 cm disk 11 has been pulled out,
By the process of 2, the carrier unit 70 is automatically returned to the eject position P1. Therefore, the process of inserting a new 8 cm disc 11, 12 cm disc 12, or disc cartridge 13 can be performed quickly.

The control device 150 constantly monitors whether or not the switch SW3 is switched from off to on in step S13. Here, referring to FIG.
Is switched from off to on is the position where SW3 engages with the second convex portion 141c of the upper cam portion 141.

In this embodiment, this SW3 is connected to the second convex portion 1
The position for engaging with 41c is set to be the 8L start position P2 (see FIG. 21B). Therefore, step 1
3, until the carrier unit 70 moves to the 8L start position P2 position.
Steps 11 and 13 are repeatedly executed.

Here, the operation of the disc lever 60 while the carrier unit 70 moves from the eject position P1 to the 8L start position P2 will be described with reference to FIG. FIGS. 11A and 11B are views of the carrier unit 70 and the disc lever 60 as viewed from the back side. FIG. 11A shows a state in which the carrier unit 70 is located at the ejection position P1, and FIG.
1 shows a state located between the 8L start position P2 and
(C) shows a state where the carrier unit 70 is located at the 8L start position P2.

When the carrier unit 70 is at the ejection position P
By moving from 1 to the 8L start position P2, a stepped cam portion N formed on the back surface of the carrier unit 70 is formed.
1 moves in the arrow Y1 direction in the figure. Accordingly, the disc lever 60 rotates counterclockwise (the direction indicated by the arrow C1 in FIG. 12) while the lever body 61 slides against the stepped cam portion N1 by the urging force of the disc lever urging spring 65. , An engagement claw 63 formed on the disc lever 60
Engages with the rear of the 8 cm disk 11 in the insertion direction as shown in FIGS.

The disc lever 60 has a lever body 61
When is separated from the stepped cam portion N1, the rear portion of the 8 cm disk 11 in the insertion direction is pressed in the disk insertion direction by the urging force of the disk lever urging spring 65.

As a result, the 8 cm disc 11 has a configuration in which the front portion in the insertion direction is held by the clip disc 74 and the rear portion in the insertion direction is held by the disc lever 60. As described above, in the present embodiment, by holding both the front part and the rear part in the insertion direction of the 8 cm disc 11, even if the 8 cm disc 11 is not mounted on the cartridge, the 8 cm disc 1
1 can be prevented from being detached from the carrier unit 70, and stable transport processing can be performed.

The rotation timing of the lever main body 61 is adjusted by a stepped cam portion N1 formed on the back surface of the carrier unit 70. Only after the maximum diameter portion in the directions of the arrows X1 and X2 (that is, the center position) has passed in the direction of the arrow Y1 in the drawing, it comes into contact with the rear portion of the 8 cm disk 11 in the insertion direction. As a result, it is possible to reduce the disk insertion load.

Now, suppose that the engaging claw 63 of the disk lever 60 engages with the 8 cm disk 11 before passing through the maximum diameter portion of the 8 cm disk 11, that is, the 8 cm disk 11 immediately starts moving when the carrier unit 70 starts moving.
As long as the engaging claw portion 63 passes through the maximum diameter portion of the 8 cm disk 11, the disk lever 60 resists the urging force of the disk lever urging spring 65 in FIG. Counterclockwise (arrow C2 in FIG. 12)
(In the direction indicated by). For this reason, in the configuration in which the engaging claw portion 63 engages with the 8 cm disk 11 before passing through the maximum diameter portion of the 8 cm disk 11, 8 cm
The disk insertion load required to insert the disk 11 increases.

On the other hand, in the present embodiment, the engaging claw 63 is configured to come into contact with the 8 cm disk 11 only after the maximum diameter portion of the 8 cm disk 11 has passed in the direction of the arrow Y1 in the figure by the cam portion N1. Therefore, when the 8 cm disc 11 is inserted, the disc lever 60 is configured to rotate only in the urging direction of the disc lever urging spring 65, so that the disc insertion load can be reduced.

On the other hand, when the carrier unit 70 moves from the eject position P1 to the 8L start position P2, the cartridge lever 77 is urged by the cartridge lever urging spring 108 so that the shaft portion 105 moves the car and the ridge lever guide groove 103. , 104 in the direction of arrow Y2 in FIG. That is, the cartridge lever 77 moves relatively to the carrier unit 70 in the direction of arrow Y2 in the figure.

However, during the movement from the ejection position P1 to the 8L start position P2, the engaging claw 106 of the cartridge lever 77 is kept in contact with the cartridge lever retraction cam 54, and thus the holder 40
The position of the cartridge lever 77 with respect to is not changed.

The carrier unit 70 shown in FIG.
Is moved to the 8L start position P2, the cartridge lever 77 extends in the direction of the arrow Y2 in the figure with respect to the front surface 89 of the carrier unit 70. However, since the carrier unit 70 moves within the disk device 10, the cartridge lever 77 does not protrude from the disk device 10.

On the other hand, if a positive determination is made in step 13 shown in FIG. 24, that is, if it is determined that the carrier unit 70 has moved to the 8L start position P2, the control device 150 A voltage (E) is applied. Accordingly, the carrier unit 70 is driven by the driving force of the loading motor 100.
The movement starts in the direction of arrow Y1 in the figure. The movement of the carrier unit 70 is performed until the center hole 11a formed in the center of the 8-cm disk 11 shown in FIG. In the following description, the center hole 11a of the 8cm disc 11 will be described.
And the carrier unit 7 where the turntable 24 matches
0 position is 8cm disc loading completion position (8L
(Abbreviated as the completion position), and is indicated by P4 in the figure. The position of the 8 cm disk 11 at this time is referred to as the loading position of the 8 cm disk.

After executing the processing in step 14, the control device 150 always determines in step 15 whether or not the switch SW2 has been switched from on to off. Here, referring to FIG. 21, the position where SW2 switches from ON to OFF is a position where SW2 is separated from convex portion 142a of lower cam portion 142 and faces concave portion 142b.

In the present embodiment, this SW2 is
Is set to be the 8L completion position P4 (see FIG. 21D). Therefore, the movement of the carrier unit 70 is continued until an affirmative determination is made in step 15, that is, until the carrier unit 70 moves to the 8L completion position P4.

When the carrier unit 70 moves from the 8L start position P2 to the 8L completion position P4, the disc lever 60 always keeps engaging with the rear portion of the 8 cm disc 11 in the insertion direction. That is, the disk lever 60 is configured to be rotatable about the rotation shaft 62 and is constantly urged by the rotation shaft 62 in a counterclockwise direction (a direction indicated by an arrow C1 in FIG. 12). Therefore, 8 cm disc 1
1 is conveyed in the direction of the arrow Y1 in the figure, the disc lever 60 rotates following this, and the disc lever 60 always maintains the state of being engaged with the rear portion of the 8 cm disc 11 in the insertion direction. Thereby, the 8L start position P
While the 8 cm disk 11 is being transported from the 2 to 8 L completion position P4, the 8 cm disk 11 is
In addition, the disc is securely held by the disc lever 60, and stable conveyance is performed.

In addition, the cartridge lever 77 is
When the carrier unit 70 moves to the 8L start position P2 as shown in FIG.
Since the carrier unit 70 has moved to the position limited to the direction of the arrow Y2 in FIGS.

At this time, the engaging claw 106 is separated from the cartridge lever retreat cam 54, and moves in the arrow Y1 direction while rotating clockwise by the urging force of the cartridge lever urging spring 108. For this reason, the cartridge lever 7
7 rotates clockwise about the shaft 105 along the right rail 50, and when the side surface of the cartridge lever 77 is separated from the edge 53a, the cartridge lever 77 is moved to the right rail as shown in FIG. A state along line 50 (a state extending in the directions of arrows Y1 and Y2 in the figure).

On the other hand, if an affirmative decision is made in step 15, that is, the 8 cm disc 11 is
When the controller 150 is conveyed to the 8L completion position P4 where the control unit 150 and the turntable 24 match, the control device 150 stops the loading motor 100 and stops the movement of the carrier unit 70 in step S16. And the following step 17
In, a clamping process is performed.

Before the clamping process, the carrier unit 70 may be moved forward and backward while reducing the moving speed in order to improve the positional accuracy of the carrier unit stop position. For example, in step 15, SW
2 is switched from on to off, the loading motor 100 is driven in the reverse direction so that the speed of the carrier unit 70 is reduced to 1/2, and subsequently, when SW2 is switched from off to on, Loading motor 1 so that the speed of carrier unit 70 becomes 1/4
00 is driven in the forward direction, and the loading motor 100 is stopped in response to the switching of SW2 from ON to OFF. By performing such an operation, the positional accuracy of the stop position of the carrier unit 70 can be improved.

In the clamping process in step 17, the above-mentioned clapper motor 68 is driven to move the holder driving slider 30 in the direction of arrow X1 in the figure (see FIG. 3).
This causes the holder 40 to move from the upward movement position shown in FIG. 4A to the downward movement position shown in FIG. 4B with the rotation shaft 57 as the center, whereby the 8 cm disk 11 also moves downward and turns. It is mounted on the table 24. Further, the clamper 58 disposed on the holder 40 as described above
4, the 8 cm disk 11 is clamped between the clamper 58 and the turntable 24 by the attraction force of the clamp magnet.

In this state, the 8 cm disk 11 is rotatable by the disk motor 25. However, the 8 cm disk 11 cannot rotate while being held by the disk lever 60. Therefore, during the clamping process, the disc lever 60
Is configured to retreat from the position where the 8 cm disk 11 is held. Hereinafter, this disk lever 60 is 8c
The operation of retracting from the position holding the m disk 11 will be described. As described above, the first and second disk lever driving cams 28 and 29 are erected on the base 20. Of these, the first disk lever drive cam 28 is
It is arranged at a position corresponding to the position of the disc lever 60 when the carrier unit 70 has moved to the 8L completion position P4.

That is, the disc lever 60 moves the carrier unit 70 in the direction of the arrow Y1 in FIG.
When the m disk 11 is conveyed in the same direction, the m disk 11 rotates about the rotation shaft 62. Then, when the 8 cm disk 11 moves to the 8L completion position P4 shown in FIG. 13 and the disk lever 60 rotates to the position shown in FIG. 13 accordingly, the engaging portion 66 formed on the disk lever 60 It is configured to face a first disk lever drive cam 28 formed on the base 20.

Therefore, as described above, the holder 40 moves from the upper position to the lower position, so that the first disk lever driving cam 28 engages with the engaging portion 66 of the disk lever 60.
14 to urge the disk lever 60 to rotate in the direction indicated by the arrow C2 in FIG. Thereby, the disk lever 6
The engaging claw portion 63 provided at 0 is separated from the 8 cm disk 11 as shown in FIG.

At this time, as shown in FIG. 4A, since the first disk lever driving cam 28 has an inclined surface, the rotation of the disk lever 60 can be smoothly performed. it can. Further, in the configuration of the present embodiment, the disk lever 60 is rotated by using the movement of the holder 40 as a drive source without separately providing a drive means such as a solenoid to separate the disk lever 60 from the 8 cm disk 11. I have. Therefore, the disk lever 60 can be reliably separated from the 8 cm disk 11 with a simple configuration.

However, when the processing in step 17 is completed, the 8 cm disk 11 is maintained in the state held by the carrier unit 70. For this reason, even if the disk lever 60 is moved away from the 8 cm disk 11, the 8cm disk 11 cannot rotate yet.

As described above, when the carrier unit 70 is transported to the 8L completion position P4, the 8 cm disc 1
1 is clamped between the clamper 58 and the turntable 24. That is, in this state, the 8 cm disk 11 cannot move in the directions of arrows Y1 and Y2 in the figure.

When the control means 150 detects that the 8-cm disc 11 has been clamped by a detection switch (not shown), the control means 150 executes step 18 and drives the loading motor 100 to move the carrier unit 70 as shown in FIG.
Move to the position shown in. In the following description,
The position of the carrier unit 70 shown in FIG. 14 is the 8 cm disc loading retreat position (abbreviated as 8 L retreat position).
And is indicated by P5 in the figure.

The control device 150 controls the carrier unit 70
Is stopped at the 8 L retreat position P5, it is determined in step 19 whether the SW3 has been switched from on to off. Here, referring to FIG. 21, the position at which SW3 switches from ON to OFF is that SW3 is the upper cam portion 141.
From the second convex portion 141c, and the second concave portion 141d.
It is a position facing.

In this embodiment, this SW3 is connected to the second recess 1
The position facing 41d is set to be the 8L retreat position P5 (see FIG. 21E). Therefore, step 1
If an affirmative determination is made in step 9, the control device 150 proceeds to step 20 and stops the loading motor 100. As a result, the carrier unit 70 is stopped at the 8L retreat position P5.

With the 8 cm disk 11 clamped as described above, the carrier unit 70 moves from the 8L completion position P4 to the 8L retreat position P5, and the 8c
The m disk 11 is separated from each clip disk 74. Thereby, the holding of the 8 cm disk 11 by the carrier unit 70 is also released, and the reproduction and / or recording processing can be performed on the 8 cm disk 11.

It is to be noted that the 8 cm disk 11 is the disk device 1
When ejected from 0, the operation is the opposite of the above-described operation at the time of mounting, and the description thereof is omitted. However, 8
When the cm disk 11 is ejected, the normal voltage (E) is applied to the loading motor 100 also from the 8L start position P2 shown in FIG. 12 to the eject position P1 shown in FIG. For this reason, the operation of the operator to remove (remove) the 8 cm disk 11 from the carrier unit 70 is performed in a state where the carrier unit 70 is at the eject position P1 shown in FIG. In this state, 8
Since the cm disk 11 is largely pulled out from the front bezel 130, the operation of removing the 8 cm disk 11 can be easily performed.

Subsequently, in step 2 shown in FIG. 23, the control device 150 is executed when an affirmative judgment is made.
Will be described. The ejection state shown in FIG. 2 (that is, the carrier unit 70 is in the ejection position P
1 state), when the 12 cm disk 12 is inserted via the front bezel 130, the 12 cm disk 12 is guided by the disk facing surface 93 and advances in the arrow Y1 direction in the figure as described above, and eventually reaches 12 cm. It abuts against the curved disk wall 95 and is held together with the 12 cm disk tongue 86-12 (clip disk 74).

When the 12 cm disk 12 comes into contact with the 12 cm disk curved wall 95, the 12 cm disk detection switch 97 is pressed by the 12 cm disk 12. Accordingly, an affirmative determination is made in step 2, and control device 150 starts the process shown in FIG.

When the processing shown in FIG. 25 is started, the control device 150 proceeds to step 30 in which the loading motor 1
00 is a loading motor assist state. That is,
Even when the 12 cm disc 12 is inserted, the control device 1
Reference numeral 50 denotes a position where the carrier unit 70 is moved from the position shown in FIG.
While moving to the position shown in FIG.
A voltage (0.2 × E) of about 20% of the normal drive voltage (E) is applied to 00, thereby improving operability when a disc is inserted. In the following description, the position of the carrier unit 70 shown in FIG. 15 is referred to as a 12 cm disc loading start position (abbreviated as a 12L start position), and is indicated by P4 in the figure.
The 12L start position P4 is the position of the 8 cm disk 11
Is set to be the same position as the 8L completion position P4 shown in FIG.

While the carrier unit 70 moves from the eject position P1 to the 12L start position P4, the control device 150 monitors the output of the 12-SW 97 in step 31. Then, in step 31, 12-SW
If it is determined that 97 has been turned off, the control device 150
Determines that the 12 cm disk 12 has been pulled out by the operator, and
0 is returned to the ejection position P1.

Therefore, even when the 12 cm disc 12 is inserted, if the operator notices the erroneous insertion, the 12 cm disc can be immediately replaced when the erroneous insertion is noticed, thereby improving the usability. Can be.
When the disk is pulled out by the processing in step 32, the carrier unit 70 is automatically returned to the eject position P1, so that a new 8 cm disk 1
The process of inserting the 1,12 cm disk 12 or the disk cartridge 13 can also be performed quickly.

On the other hand, when the carrier unit 70 moves from the ejection position P1 to the 12L start position P4, the stepped cam portion N1 formed on the back surface of the carrier unit 70 moves in the direction of arrow Y1 in the figure. As a result, the disk lever 60 is moved to the disk lever biasing spring 6.
5 causes the lever body 61 to move to the stepped cam portion N.
1 while rotating in the counterclockwise direction (the direction indicated by arrow C1 in FIG. 15), the engaging claw 63 formed on the disc lever 60 inserts the 12 cm disc 12 as shown in FIG. Engages the rear part in the direction. Disc lever 60
After the lever main body 61 is separated from the stepped cam portion N1 by the urging force of the disc lever urging spring 65,
Press the 12 cm disc 12.

Thus, even when the 12 cm disc 12 is inserted, the front of the 12 cm disc 12 is held by the clip disc 74 and the rear of the 12 cm disc 12 is held by the disc lever 60. Accordingly, the 12 cm disc 12 is held at both the front and rear sides in the insertion direction, so that even the 12 cm disc 12 not configured to be mounted on the cartridge can be prevented from detaching from the carrier unit 70, Stable transport processing can be performed.

On the other hand, when the carrier unit 70 moves from the eject position P1 to the 12L starting position P4, the cartridge lever 77 is urged by the cartridge lever urging spring 108 so that the shaft portion 105 moves the cartridge lever guide grooves 103, 104. In the direction of arrow Y2 in the figure. That is, the cartridge lever 77 moves relatively to the carrier unit 70 in the direction of arrow Y2 in the figure. Also, when the 12 cm disc 12 is inserted,
The L start position P4 is compared with the 8L start position P2 when the 8 cm disk 11 described above is inserted, as indicated by an arrow Y1 in the drawing.
It is set at a position separated by a predetermined distance in the direction.

For this reason, the 12L
With the movement to the start position P4, the cartridge lever 77
The engagement claw 106 is separated from the cartridge lever retraction cam 54, and moves in the arrow Y1 direction while rotating clockwise by the urging force of the cartridge lever urging spring 108. As a result, the cartridge lever 77 moves the right rail 5
It rotates clockwise about the shaft 105 so as to be along 0, and becomes a state along the right rail 50 (a state extending in the directions of arrows Y1 and Y2 in the figure) as shown in FIG.

Here, returning to FIG.
The description of the control operation will be continued. The controller 150 constantly monitors whether or not the switch SW2 is switched from on to off in step 33. Here, referring to FIG. 21, the position where SW2 switches from on to off is SW2
Is detached from the convex portion 142a of the lower cam portion 142 and the concave portion 14
2b.

In the present embodiment, this SW2 is
Is set to be the 12L start position P4 (see FIG. 21D). Therefore, the processes of steps 31 and 33 are repeatedly executed until an affirmative determination is made in step 33, in other words, until the carrier unit 70 moves to the 12L start position P4.

On the other hand, if a positive determination is made in step 33 shown in FIG. 25, that is, if it is determined that carrier unit 70 has moved to 12L start position P4, control device 150
Applies a regular voltage (E) to the loading motor 100 in step 34. As a result, the carrier unit 70 starts moving in the arrow Y1 direction in the figure by the driving force of the loading motor 100. The movement of the carrier unit 70 is performed until the center hole 12a formed in the center of the 12 cm disk 12 shown in FIG. In the following description, the position of the carrier unit 70 where the center hole 12a of the 12cm disk 12 and the turntable 24 coincide with each other is referred to as a 12cm disk loading completion position (abbreviated as 12L completion position), which is indicated by P5 in the figure. And The 12L completion position P5 is 8
When the cm disk 11 is being conveyed, as shown in FIG.
It is set to be the same position as the L evacuation position P5. Further, the carrier unit 70 is moved to the 12L completion position P5.
The position of the 12 cm disc 12 when
This is referred to as the loading position of the cm disk.

After performing the processing in step S34, the control device 150 always determines in step S35 whether or not the switch SW3 has been switched from on to off. Here, referring to FIG. 21, the position where SW3 switches from ON to OFF is a position where SW3 is separated from second convex portion 141c of upper cam portion 141 and faces second concave portion 141d.

In this embodiment, this SW3 is connected to the second recess 1
The position facing 41d is set to be the 12L completion position P5 (see FIG. 21E). Therefore, until the affirmative determination is made in step 35, in other words, until the carrier unit 70 moves to the 12L completion position P5,
The movement of the carrier unit 70 is continued.

When the carrier unit 70 moves from the 12L start position P4 to the 12L completion position P5, the disk lever 60 is always engaged with the rear portion of the 12cm disk 12 in the insertion direction, as in the case of transporting the 8cm disk 11. maintain. Therefore, while the 12 cm disk 12 is being conveyed from the 12L start position P4 to the 12L completion position P5,
The 12 cm disk 12 is securely held by the carrier unit 70 and the disk lever 60, and is transported in a stable state.

In this embodiment, the disc lever 60 is rotatably disposed on the holder 40, so that the rear of the 8cm disc 11 and the 12cm disc 12 having different diameters in the insertion direction can be held by one disc lever 60. It is configured to do this. Thereby, the disk drive 10
The number of parts can be reduced and the configuration can be simplified.

On the other hand, if an affirmative determination is made in step 35 and it is determined that the 12 cm disk 12 has been transported to the 12L completion position P5 where the center hole 12a and the turntable 24 match, the control device 150 loads in step 36. The motor 100 is stopped, and the movement of the carrier unit 70 is stopped. Then, the clamp process of the following step 37 is performed. The processing in step 37 is the same as the clamp processing in step 17 shown in FIG.

More specifically, the clamping motor 68 is driven to move the holder driving slider 30 in the direction of the arrow X1 in the figure (see FIG. 3). As a result, the holder 40 is positioned as shown in FIG.
4A from the upward movement position shown in FIG.
(B), the 12 cm disc 12 is also moved down and attached to the turntable 24, and is clamped between the clamper 58 and the turntable 24.

In this state, the 12 cm disc 12
Become rotatable by the disk motor 25. However, the 12 cm disk 12 cannot rotate while being held by the disk lever 60. For this reason, the disc lever 60 is configured to retreat from the position for holding the 12 cm disc 12 during the clamping process. Hereinafter, this disk lever 6
The operation of retracting from the position where 0 holds the 12 cm disk 12 will be described. As described above, the first and second disk lever driving cams 28 and 29 are erected on the base 20. Of these, the second disk lever drive cam 29 is configured such that the carrier unit 70 is in the 12L completion position P5.
It is disposed at a position corresponding to the position of the disk lever 60 when the disk lever 60 has moved to the position shown in FIG.

That is, when the carrier unit 70 moves in the arrow Y1 direction in the figure, the disc lever 60
When the 2 cm disc 12 is conveyed in the same direction, it rotates about the rotation shaft 62. And 12cm
When the disk 12 moves to the 12L completion position P5 shown in FIG. 16 and the disk lever 60 rotates to the position shown in FIG. 13 accordingly, the engaging portion 66 formed on the disk lever 60 It is configured to face the formed second disk lever drive cam 29.

Therefore, as the holder 40 moves from the upper position to the lower position as described above, the second disk lever driving cam 29 is moved to the engagement portion 66 of the disk lever 60.
To bias the disk lever 60 in the direction indicated by the arrow C2 in FIG. Thereby, the disk lever 6
The engagement claw 63 provided on the disc 0 is separated from the 12 cm disk 12 as shown in FIG.

At this time, the second disk lever driving cam 2
9 has an inclined surface similar to the first disk lever drive cam 28 described above, so that the disk lever 6
The rotation bias of 0 can be performed smoothly. Also, 12
Even when the cm disk 12 is being transported, the disk lever 60 is rotated using the movement of the holder 40 as a drive source without using any other driving means to separate the disk lever 60 from the 12 cm disk 12. The configuration of the device 10 can be simplified.

However, at the time when the process of step 37 is completed, the state in which the 12 cm disk 12 is held by the carrier unit 70 is maintained. For this reason, even if the disk lever 60 is separated from the 12 cm disk 12, the 12 cm disk 12 cannot be rotated yet.

As described above, when the carrier unit 70 is transported to the 12L completion position P5, the 12 cm disc 12 is clamped between the clamper 58 and the turntable 24. That is, in this state, the 12 cm disk 12 cannot move in the directions of the arrows Y1 and Y2 in the drawing.

When the control means 150 detects that the 12 cm disk 12 has been clamped by a detection switch (not shown), the control means 150 executes step 38 and drives the loading motor 100 to move the carrier unit 70 as shown in FIG.
Move to the position shown in 7. In the following description, the position of the carrier unit 70 shown in FIG.
It is referred to as an m disk loading retreat position (abbreviated as a 12L retreat position) and is indicated by P6 in the figure.

The control device 150 controls the carrier unit 70
Is stopped at the 12L evacuation position P6 in step 39.
It is determined whether or not SW3 has been switched from off to on. Here, referring to FIG. 21, the position at which SW3 switches from OFF to ON is determined by the position of SW3
The first concave portion 141d is separated from the first second concave portion 141d.
e (see FIG. 21F).

In this embodiment, this SW3 is connected to the third recess 1
The position to be engaged with 41e is set to be the 12L retreat position P6. Therefore, when an affirmative determination is made in step 39, the control device 150 proceeds to step 40 and stops the loading motor 100. Thereby, the carrier unit 70 is stopped at the 12L retreat position P6.

When the carrier unit 70 moves from the 12L completion position P5 to the 12L retreat position P6 with the 12cm disk 12 clamped as described above, the 12cm disk 12 is separated from each clip disk 74. Thereby, the holding of the 12 cm disk 12 by the carrier unit 70 is also released, and the reproduction and / or recording processing can be performed on the 12 cm disk 12.

The operation at the time of ejecting the 12 cm disk 12 is the opposite operation to the operation at the time of loading, and the description is omitted. However, even when the 12 cm disk 12 is ejected, the normal voltage (E) is applied to the loading motor 100 from the 12L start position P4 shown in FIG. 12 to the eject position P1 shown in FIG. For this reason, the operator can change the carrier units 70 to 12
The operation of taking out (removing) the cm disk 12 is performed in a state where the carrier unit 70 is at the ejection position P1 shown in FIG. In this state, 12cm
Since the disk 12 is largely pulled out from the front bezel 130, the operation of removing the 12 cm disk 12 can be easily performed.

Subsequently, in step 3 shown in FIG. 23, the control device 150 is executed when an affirmative judgment is made.
Will be described.

When the disk cartridge 13 is inserted into the ejected disk device 10 shown in FIG. 2 via the front bezel 130, the tip of the disk cartridge 13 first comes into contact with the front surface 89 of the carrier unit 70. Since a disk cartridge detection switch 98 is provided on the front surface 89 (see FIG. 10), the disk cartridge 13 is moved to the front surface 8 of the carrier unit 70.
9, the disc cartridge detection switch 98 is pressed. Accordingly, an affirmative determination is made in step 3, and the control device 15
0 starts the processing shown in FIG. When the disc cartridge 13 is in contact with the carrier unit 70, the shutter drive pin 113 provided on the shutter lever 78 is engaged with the end of the shutter 15 provided on the disc cartridge 13.

When the processing shown in FIG. 26 is started, the control device 150 proceeds to step 50 where the loading motor 1
00 is a loading motor assist state. That is,
Even when the disc cartridge 13 is inserted, while the carrier unit 70 moves from the position shown in FIG. 2 to the position shown in FIG. 18, the control device 150 controls the loading motor 100 by about 20% of the normal driving voltage (E). (0.2 × E) is applied to improve the operability when the disc is inserted. In the following description, the position of the carrier unit 70 shown in FIG. 18 is referred to as a disk cartridge loading start position (abbreviated as DL start position), and is indicated by P3 in the figure.

While the carrier unit 70 moves from the eject position P1 to the DL start position P3, the control device 150 monitors the output of the DC-SW 98 in step 51. Then, in step 51, the DC-SW 98
Is determined to have been turned off, the control device 150 determines that the disk cartridge 13 has been pulled out by the operator,
0 is returned to the ejection position P1.

Therefore, even when the disc cartridge 13 is inserted, if the operator notices the erroneous insertion, the disc cartridge can be replaced immediately when the operator notices the erroneous insertion, thereby improving the usability. Can be. Further, when the disk cartridge is pulled out by the processing of step 52, the carrier unit 70 is automatically returned to the eject position P1, so that the processing of inserting a new 8 cm disk 11, 12cm disk 12, or disk cartridge 13 can be promptly performed. Can be performed.

When the carrier unit 70 moves from the eject position P1 to the DL start position P3, the disk lever 60 is retracted to a position where it does not hinder the insertion of the disk cartridge 13. That is, the carrier unit 70 moves from the eject position P1 to the DL start position P3.
, The lever body 61 of the disk lever 60 is separated from the stepped cam portion N1 on the rear surface of the carrier unit 70. However, as described above, since the disc cartridge 13 is in contact with the front surface 89 of the carrier unit 70, even if the lever main body 61 is separated from the cam portion N1, the engaging claw portion 63 continues to be Abut on the side of Therefore, the disc lever 60 maintains the position when the carrier unit 70 is at the ejection position P1, and the disc lever 60 does not hinder the insertion of the disc cartridge 13.

On the other hand, the carrier unit 70 starts moving from the ejection position P1 in the direction of arrow Y1 in the figure, and
When the cartridge lever 77 moves to the position indicated by P2 (this position is the same as the 8L start position P2 shown in FIG. 12), the cartridge lever 77 moves relative to the carrier unit 70 in the direction of the arrow Y2 with this movement. . When the carrier unit 70 moves to the position P2, the shaft portion 105 of the cartridge lever 77 has moved to the limit position of the cartridge lever guide grooves 103 and 104 in the direction of arrow Y2 in the drawing.

During the movement of the carrier unit 70 from the ejection position P1 to the position P2, the engaging claw 106 of the cartridge lever 77 is kept in contact with the cartridge lever retraction cam 54, and thus the holder 40
The position of the cartridge lever 77 with respect to is not changed. However, as described above, the cartridge lever 7
When the cartridge 7 moves in the direction of the arrow Y2 with respect to the carrier unit 70, the cartridge lever 77 extends from the front surface 89 of the carrier unit 70 in the direction of the arrow Y2 in the figure.

When the carrier unit 70 further moves from the position P2 to the DL start position P3, as described above, when the carrier unit 70 moves to the position P2, the shaft 105 is moved to the cartridge lever guide grooves 103, 1 as described above.
Since the cartridge lever 77 has moved to the position limited to the direction of the arrow Y2 in FIG. 04, the cartridge lever 77 moves in the direction of the arrow Y1 together with the carrier unit 70.

As a result, the engaging claw 106 is separated from the cartridge lever retreat cam 54, and the cartridge lever 77 moves in the arrow Y1 direction while rotating clockwise by the cartridge lever urging spring 108. Therefore, the cartridge lever 77 is moved by the cartridge lever urging spring 1.
08 to rotate clockwise about the shaft 105. An engagement recess 16 is formed on the side surface of the disc cartridge 13, and the formation position of the engagement recess 16 is located on the movement locus of the engagement claw 106 of the cartridge lever 77 that rotates as described above. It is configured as follows.

Therefore, by the rotation of the cartridge lever 77, the engaging claw 106 is engaged with the engaging concave portion 16 of the disk cartridge 13 as shown in FIG. When the side surface of the cartridge lever 77 is separated from the edge 53 a with the movement of the carrier unit 70, the cartridge lever 77 maintains the state in which the engaging claw 106 is engaged with the engaging concave portion 16 while maintaining the right rail. A state along line 50 (a state extending in the directions of arrows Y1 and Y2 in the figure).

Further, with the movement of the carrier unit 70, the shutter lever 78 rotates. Specifically, since the shutter drive pin 113 disposed on the shutter lever 78 is engaged with the slit 126, the shutter drive pin 113 is guided by the slit 126 and moves with the insertion of the carrier unit 70. .

Thus, the shutter lever 78 rotates, and the shutter 15 engaged with the shutter drive pin 113 is opened. When the shutter 15 is completely opened, the shutter driving pin 113 is disengaged from the slit 126 as described above, and the movement of the shutter lever 78 is restricted by the engagement hole 111 engaging the leaf spring 79. Is done.

Here, returning to FIG.
The description of the control operation will be continued. The controller 150 constantly monitors whether or not SW1 has been switched from off to on in step 53, and whether or not SW3 has been switched from on to off in step 54. here,
Referring to FIG. 21, the position where both SW1 and SW3 are turned on is the position shown in FIG. 21C, and in this embodiment, this position is set to be the DL start position P3. Accordingly, until the affirmative determination is made in both steps 53 and 54, in other words, the carrier unit 70
Until the movement to the start position P3, the processing of steps 51 to 54 is repeatedly executed.

On the other hand, if an affirmative decision is made in both steps 53 and 54, that is, the carrier unit 70
If it is determined that the motor has moved to the L start position P3, the control device 150
A normal voltage (E) is applied to 0. As a result, the carrier unit 70 starts moving in the arrow Y1 direction in the figure by the driving force of the loading motor 100. The movement of the carrier unit 70 is performed until the center hole 14a of the DVD-RAM 14 provided in the disk cartridge 13 shown in FIG.

Incidentally, in the following description, the DVD-RAM
The position of the carrier unit 70 where the center hole 14a of the 14 coincides with the turntable 24 is called a disk cartridge loading completion position (abbreviated as DL completion position), and is indicated by P6 in the figure. Also, this D
The L completion position P6 is set to be the same position as the 12L retreat position P6 shown in FIG. 17 when the 12 cm disk 12 is transported. Further, the carrier unit 7
The position of the disk cartridge 13 when 0 is at the DL completion position P6 is referred to as the loading position of the disk cartridge.

Also when the carrier unit 70 moves from the DL start position P3 to the DL completion position P6, the disk lever 60 contacts the side surface of the disk cartridge 13,
The retracted position is maintained so as not to hinder the transportation of the disk cartridge 13.

Further, after executing the processing in step 55, the control device 150 determines in step 56 and step 57 whether or not the switch SW3 is switched from on to off, and thereafter, whether the switch SW3 is switched from off to on. . Here, referring to FIG. 21, the position where SW3 switches from on to off and then switches from off to on is
This is the position shown in FIG.

In this embodiment, the position shown in FIG. 21F is set to be the DL completion position P6. Therefore, until the affirmative determination is made in both steps 56 and 57, in other words, the carrier unit 70
Until the carrier unit 70 moves to the L completion position P6.
The movement of is continued.

On the other hand, if an affirmative decision is made in both steps 56 and 57, the control device 150 stops the loading motor 100 in step 58.
As a result, the carrier unit 70 moves to the DL completion position P6.
Stop at In the subsequent step 59, the control device 1
Reference numeral 50 drives the clapping motor 68 to move the holder driving slider 30 in the direction of arrow X1 in the figure (see FIG. 3). As a result, the holder 40 moves from the upper movement position shown in FIG. 4A to the lower movement position shown in FIG. 4B around the rotation shaft 57, and accordingly, the disk cartridge 13 also moves down.

Thus, the DVD-RAM 14 provided in the disc cartridge 13 is mounted on the turntable 24 and clamped between the clamper 58 and the turntable 24. As a result, the DVD-RAM 14 becomes rotatable by the disk motor 25 and the DVD-RA
Reproduction / recording processing becomes possible for M14.

When the disk cartridge 13 is ejected from the disk device 10, the operation is the opposite of the above-described operation at the time of mounting, and the description thereof is omitted.
However, when the disc cartridge 13 is ejected,
The normal voltage (E) is applied to the loading motor 100 during the entire period from the DL completion position P6 to the ejection position P1 in order to improve the removal operability.

As described above, according to the present embodiment, SW1 to SW1
