[0004]

However, in the conventional cartridge mounting device, the arm member for opening and closing the cartridge shutter always slides on the guide slit while the tray moves from the cartridge insertion position to the cartridge mounting position. Therefore, the sliding resistance always acts on the tray.

Therefore, conventionally, there has been a problem that the load on the tray drive motor for driving the tray is increased by the sliding resistance of the arm member, and the tray drive motor cannot be reduced in size accordingly.

Accordingly, it is an object of the present invention to provide a cartridge mounting device which solves the above-mentioned problems.

[0007]

The present invention has the following features to solve the above-mentioned problems.

According to the first aspect of the present invention, the shutter provided on the cartridge is moved by the operation of the shutter opening / closing member while the cartridge containing the recording medium is moved to the mounting position as the cartridge is inserted. In a cartridge mounting device that opens and closes, the shutter opening and closing member is provided to be swingable, and a conveying member that grips the cartridge inserted at the insertion position and conveys the cartridge to the mounting position, or ejects the cartridge at the mounting position to the insertion position. A cam portion that engages with the shutter opening / closing member to open and close the shutter of the cartridge in a part of a process of moving from the insertion position to the mounting position, and engages with the cam portion to move the shutter of the cartridge. A holding member for holding the shutter opening / closing member in a state displaced to an open position. Cage, it is possible to shutter closing member to reduce the load in the process of transporting the cartridge to shorten the distance to be engaged with the cam portion.

According to a second aspect of the present invention, the holding member is provided on the conveying member, and the shutter opening / closing member is locked when the shutter opening / closing member passes the cam portion in the process of mounting the cartridge. In order to release the lock of the shutter opening / closing member when the shutter opening / closing member engages with the cam portion during the ejecting operation, the shutter opening / closing member that has passed through the cam portion without being engaged with the cam portion is moved to the shutter open position. Thus, the distance in which the shutter opening / closing member is engaged with the cam portion can be shortened to reduce the load in the process of transporting the cartridge.

As described above, the 8 cm disk 11 or 1
The left and right ends of the 2 cm disk 12 are clamped by the first and second clip disks 74-1 and 74-2 and the third and fourth clip disks 74-3 and 74-4.

Here, paying attention to the arrangement positions of the tongue pieces 86 formed on the clip disks 74 to 76, FIG.
This will be described with reference to FIGS. As described above, each of the clip disks 74 to 76 has a pair of tongue pieces 8.
6, each of the clip disks 74 to 76
Is disposed, one tongue piece 86 is 8 cm
The disposition position is set so as to face the curved wall 94 for the disk (hereinafter, when the tongue portion 86 is specified and described, the tongue portion 86 is referred to as an 8 cm disk tongue portion 86-8). . The position of the other tongue piece 86 is set so as to face the curved wall 95 for a 12 cm disk (hereinafter, when the tongue piece 86 is specified and described, the tongue piece 86 is used). Is referred to as a 12 cm disc tongue piece 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 leave from.

On the other hand, in the present embodiment, the tongue piece 86 provided on the clip disks 74 to 76 as described above is used.
Are arranged so as to gradually approach each other in the insertion direction (the direction of the arrow Y1 in the drawing) and abut against the outer peripheral edges of the disks 11, 12. For this reason, in the holding state shown in FIG.
When a force (pulling force) is applied to the discs 11 and 12 in the direction of pulling out from the carrier unit 70, the pulling force generates a force indicated by an arrow B in the tongue piece portion 86, and this force is applied to the contact portion. 88 acts as a force for pressing the discs 11 and 12. Thereby, the disks 11, 1
2 to the carrier unit 70 (clip disks 74 to 7).
Even if the pull-out force is applied to the discs 11 and 12 by mistake after the holding in step 6), the discs 11 and 12 can be prevented from being detached from the carrier unit 70 (clip discs 74 to 76).

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 provided on the disk curved walls 94 and 95, respectively. However, the positions of the disk detection switches 96 and 97 may be set to positions opposed to the third clip disk 76 of the lower left half 73. FIG. 9 shows an example in which the disk detection switches 96 and 97 are arranged at positions facing the third clip disk 76. Disk detection switches 96 and 97
Has a contact portion 99 that is pressed by the insertion of the disks 11 and 12. This contact portion 99 is shown in FIG.
, And is urged upward by a spring (not shown) arranged in the switch body. The disc detection switches 96 and 97 are arranged such that the contact portion 99 faces the contact portion 88 of the third clip disc 76 as shown in FIG. 9A.

Therefore, when the disks 11, 12 are inserted into the carrier unit 70, as shown in FIG.
The discs 11 and 12 are sandwiched between the third clip disc 76 and the disc detection switches 96 and 97. Further, since the tongue piece portion 86 has a spring property and the contact portion 99 is urged upward, the disks 11 and 12 are connected to the third clip disk 76 and the disk detection switches 96 and 97. Firmly held between
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 75 disposed on the lower right half 72 in addition to the function as the switch. Thus, 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 top plate 121 has first and second concave portions 1.
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 structure 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 vertically between the base 20 and the base cover 120 (see 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 opening 133 is provided for the cover 13 except when the discs 11 and 12 and the disc cartridge 13 are inserted and removed.
1, 132, thereby preventing dust from entering the disk device 10.

Subsequently, the disk device 1 having the above configuration
The operation of 0 will be described. FIG. 2 shows disks 11, 1
2 shows the disk device 10 without the disk cartridge 13 inserted. 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, the lever body 61 of the disc lever 60
11A, as shown in FIG. 11A, is in contact with a step-shaped cam portion N1 formed on the back surface of the carrier unit 70. Thereby, the disk lever 60
Resists the urging force of the disc lever urging spring 65, and retracts to a position where the engaging claw 63 does not hinder the movement of the carrier unit 70. Also, the cartridge lever 77
Is configured to be displaceable in the directions indicated by arrows Y1 and Y2 with respect to the carrier unit 70 by moving the shaft portion 105 in the cartridge lever guide grooves 103 and 104 as described above. Also, 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 ejection position P1, the engaging claw 106 formed on the cartridge lever 77 is configured to engage with the cartridge lever retreat cam 54 disposed 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 retracting 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.
When the engaging claw 106 is pressed against the inclined surface by the elastic force of (1), the engaging claw 106 is displaced along the inclined surface.

However, outside the cartridge lever 77 (X2 direction side), the cover N2
(A part of which is shown in FIG. 2). Therefore, when the outer side surface of the cartridge 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. Therefore, the cartridge lever 77 is also displaced with respect to the carrier unit 70 in the arrow Y1 direction 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 drive 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 rotated clockwise 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 start position where engagement with a shutter 15 formed on the inserted disk cartridge 13 is started.

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. 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 disk 11, 12 or the disk cartridge 13 is inserted into the disk device 10 in the ejected state, the disk device 10 starts the carrying operation. Hereinafter, this transfer operation will be described with reference to the 8 cm disks 11, 12c.
The description will be given separately for the m disk 12 and the disk cartridge 13.

First, the transport operation when the 8 cm disk 11 is inserted into the disk device 10 will be described with reference to FIGS. 8c via the front bezel 130 to the disk device 10 in the ejected state shown in FIG.
When the m disk 11 is inserted, the 8 cm disk 11 is guided by the disk facing surface 93 and proceeds in the direction of the arrow Y1 in FIG.
8cm disc tongue piece 86-8
(Clip disks 74 to 76) (see FIGS. 7 to 9).

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. This allows the control device to control the 8 cm disc 11
Is held by the carrier unit 70.

The 8 cm disk 11 is used for the carrier unit 7
When it is detected that the value is held at 0, the control device 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 determines that the driving voltage applied to the loading motor 100 is half of the normal driving voltage (E volt) until the carrier unit 70 moves from the position shown in FIG. (E / 2).

[0093] Specifically, the carrier unit 70 corresponds to FIG.
During the movement from the eject position P1 shown in FIG. 12 to the position shown in FIG. 12, a voltage (E / 2) of about half of the normal drive voltage (E) is applied to the loading motor 100.
In the following description, the carrier unit 70 shown in FIG.
The position shown in FIG. 2 is called an 8 cm disc loading start position (abbreviated as 8L start position), and is indicated by P2 in the figure.

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 operation of the disk 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 disk lever 60 includes 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 disk 11 has a configuration in which the front part in the insertion direction is held by the clip disks 74 to 76 and the rear part in the insertion direction is held by the disk lever 60. Thus, in this embodiment, 8 cm
By holding both the front part and the rear part in the insertion direction of the disc 11, it is possible to prevent the 8 cm disc 11 from being detached from the carrier unit 70 even in the case of the 8 cm disc 11 which is not mounted on the cartridge. , It is possible to perform a stable transport process.

The pivoting operation 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. Therefore, there is no need to rotate the disk lever 61 in the direction of arrow C2 against the urging force of the disk lever urging spring 65 due to the outer periphery of the disk. With this configuration, a disk device with a low disk insertion load can be realized.

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 cartridge lever guide grooves 103 and 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.

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 retreating cam 54, so that 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.

As described above, the carrier unit 70 is 8L.
After moving to the start position P2, the control device applies the regular voltage (E) to the loading motor 100. 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. Then, as shown in FIG.
1 is transported to a position where the center hole 11a formed in the center thereof and the turntable 24 coincide with each other.
The control device stops the conveyance of the 8 cm disk 11 once.
In the following description, the position of the carrier unit 70 where the center hole 11a of the 8cm disk 11 and the turntable 24 coincide with each other is referred to as an 8cm disk loading completion position (abbreviated as 8L completion position).
It is assumed that The position of the 8-cm disc 11 at this time is referred to as a loading position.

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.

Further, 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 coil spring 108. For this reason, the cartridge lever 77 is
In a state where the side surface of the cartridge lever 77 is separated from the edge 53a in the clockwise direction around the shaft portion 105 so that the cartridge lever 77 is along the right rail 50 as shown in FIG. (In the figure, the state extends in the directions of arrows Y1 and Y2).

As described above, the 8 cm disc 11 is the 8L disc whose center hole 11a coincides with the turntable 24.
When transported to the completion position P4, the control device drives the above-described slide motor to move the holder driving slider 30 in the direction of arrow X1 in the figure (see FIG. 3). This allows
The holder 40 is moved from the upper position shown in FIG.
4B, the 8 cm disc 11 is also moved downward, and the turntable 2 is moved downward.
4 is attached. Further, as described above, the clamper 58 provided on the holder 40 is attracted to the turntable 24 by the attraction force of the clamp magnet.
The m disk 11 is clamped between the clamper 58 and the turntable 24.

As a result, the 8 cm disk 11 becomes rotatable by the disk motor 25. However, the 8 cm disk 11 cannot rotate while being held by the carrier unit 70 and the disk lever 60 described above. For this reason, 8cm disc 1
After 1 is clamped, the carrier unit 70 and the disk lever 60 are configured to retract from the position where the 8 cm disk 11 is held.

First, the operation of retracting the disk lever 60 from the position where the 8 cm disk 11 is held will be described. As described above, the first and second disk drive cams 28 and 29 are erected on the base 20. Of these,
The first disk drive cam 28 is
Is located at a position corresponding to the position of the disk lever 60 when it is moved to the 8L completion position P4 position.

That is, the disc lever 60 moves the carrier unit 70 in the direction of 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 drive cam 28 formed on the base 20.

Accordingly, the first disk drive cam 28 engages with the engaging portion 66 of the disk lever 60 by moving the holder 40 from the upper position to the lower position as described above, and It is urged to rotate in the direction indicated by arrow C2 in FIG. As a result, the engaging claw 63 provided on the disc lever 60 becomes 8c as shown in FIG.
Separated from the disk 11. At this time, as shown in FIG. 4A, the first disk drive cam 28 has a tapered surface, so that the rotation of the disk lever 60 can be smoothly performed.

Next, the operation of the carrier unit 70 retracting from the position for holding the 8 cm disk 11 will be described. As described above, the carrier unit 70 is 8L.
When transported to the completion position P4, the 8 cm disk 11 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 detects that the 8 cm disk 11 is clamped between the clamper 58 and the turntable 24 by a detection switch (not shown), the loading motor 100 is driven again, and the carrier unit 7 is turned on.
0 is moved to the position shown in FIG. In the following description, the position of the carrier unit 70 shown in FIG. 14 is referred to as an 8 cm disc loading retreat position (abbreviated as 8L retreat position), and is indicated by P5 in the drawing.

When the 8 cm disk 11 is clamped as described above, the carrier unit 70 is moved to the 8L completion position P.
By moving from the 4 position to the 8L retreat position P5, 8
The cm disk 11 is separated from each of the clip disks 74 to 76. Thereby, 8 by the carrier unit 70
The holding of the cm disk 11 is also released.

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 operator needs to
The operation of taking out (removing) the 8 cm disk 11 from is performed in a state where the carrier unit 70 is at the ejection 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, referring to FIG. 15 to FIG.
The transport operation when the m disk 12 is inserted into the disk device 10 will be described. When the 12 cm disc 12 is inserted into the ejected disc device 10 shown in FIG.
The 2 cm disk 12 is guided by the disk facing surface 93 and advances in the direction of the arrow Y1 in the figure, and then comes into contact with the curved wall 95 for the 12 cm disk. Is held.

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. Thereby, the control device detects that the 12 cm disk 12 is held by the carrier unit 70.

When it is detected that the 12 cm disk 12 is held by the carrier unit 70, the control device starts applying a voltage to the loading motor 100. At this time, even when the 12-cm disc 12 is inserted, the control device moves the carrier unit 70 from the position shown in FIG.
During the movement to the position shown in FIG.
Voltage (E / 2) that is half of the normal drive voltage (E) with respect to 0
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. 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. In addition, this 1
The 2L start position P4 is set to be the same as the 8L completion position P4 shown in FIG. 13 when the 8 cm disk 11 is transported.

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 disk 12 is inserted, the front of the 12 cm disk 12 in the insertion direction is held by the clip disks 74 to 76, and the rear of the insertion direction is held by the disk lever 60. Therefore, the 12 cm disc 12 is held at both the front part and the rear part in the insertion direction.
2 can be prevented from being separated from the carrier unit 70, and a stable transport process 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 of the carrier unit 70
With the movement to the start position P4, the cartridge lever 77
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 coil spring 108. As a result, the cartridge lever 77 rotates clockwise about the shaft 105 along the right rail 50, and moves along the right rail 50 as shown in FIG. State).

As described above, the carrier unit 70
When the control device moves to the L start position P4, the control device applies the regular voltage (E) to the loading motor 100, whereby the carrier unit 70 independently starts moving in the arrow Y1 direction in the figure. Then, as shown in FIG.
When the cm disk 12 is transported to a position where the center hole 12a formed in the center thereof and the turntable 24 coincide with each other, the control device temporarily stops transporting the 12 cm disk 12. In the following description, the center hole 12a of the 12 cm disc 12 and the turntable 2
The position of the carrier unit 70 corresponding to 4 is 12 cm
It is referred to as a disc loading completion position (abbreviated as a 12L completion position) and is indicated by P5 in the figure. The position of the 12 cm disk 12 at this time is referred to as a loading position.

When the carrier unit 70 moves from the 12L start position P4 to the 12L completion position P5, the disc lever 60 always engages with the rear portion of the 12cm disc 12 in the insertion direction, as in the case of transporting the 8cm disc 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 disk lever 60 is rotatably disposed on the holder 40, so that the rear of the 8 cm disks 11 and 12 cm disks 12 having different diameters in the insertion direction can be held by one disk 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.

As described above, when the center hole 12a and the turntable 24 coincide with each other,
When transported to the 2L completion position P5, the control device drives the above-described slide motor 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.
Accordingly, the 12 cm disk 12 is also moved down and mounted on the turntable 24 and clamped between the clamper 58 and the turntable 24.

As a result, the 12 cm disk 12 becomes rotatable by the disk motor 25. However, in the state held by the carrier unit 70 and the disc lever 60, the 12 cm disc 1
2 cannot rotate. For this reason, after the 8 cm disk 11 is clamped, the carrier unit 70 and the disk lever 60 are configured to retreat from the position where the 12 cm disk 12 is held.

First, the operation of the disk lever 60 retracting from the position for holding the 12 cm disk 12 will be described. As described above, the first and second disk drive cams 28 and 29 are erected on the base 20. Among them, the second disk drive cam 29 is used when the carrier unit 70 moves to the 12L completion position P5.
It is provided at a position corresponding to the position of the disk lever 60.

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 drive cam 29.

Accordingly, the second disk drive cam 29 is engaged with the engaging portion 66 of the disk lever 60 by moving the holder 40 from the upper position to the lower position as described above, and the disk lever 60 is moved. It is urged to rotate in the direction indicated by arrow C2 in FIG. As a result, the engaging claw 63 provided on the disc lever 60 is
Separated from the cm disk 12. At this time, since the second disk drive cam 29 has a tapered surface similar to the first disk drive cam 28, the rotation of the disk lever 60 can be smoothly performed.

Subsequently, the carrier unit 70 is 12 cm
The operation of retracting from the position where the disk 12 is held will be described.

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, and moves in the directions of arrows Y1 and Y2 in the figure. Impossible. When the control means detects that the 12 cm disk 12 has been clamped by a detection switch (not shown), it drives the loading motor 100 again to move the carrier unit 70 to the position shown in FIG.
In the following description, the position of the carrier unit 70 shown in FIG. 17 is referred to as a 12 cm disc loading retreat position (abbreviated as 12L retreat position), and is indicated by P6 in the drawing.

When the carrier unit 70 moves from the 12L completion position P5 to the 12L retreat position P6 in the state where the 12cm disk 12 is clamped as described above, the 12cm disk 12
Depart from 76. Thereby, the carrier unit 70

It becomes possible to perform reproduction and / or recording processing on the m disk 12.

When the 12-cm disk 12 is ejected from the disk device 10, the operation is the opposite of the operation at the time of loading, and the description is omitted. However, even when the 12 cm disc 12 is ejected, 12 c
The normal voltage (E) is applied to the loading motor 100 also from the 12L start position P4 shown in FIG. 15 to the eject position P1 shown in FIG. .

Next, a transport operation when the disk cartridge 13 is inserted into the disk device 10 will be described with reference to FIGS. When the disc cartridge 13 is inserted into the ejected disc device 10 shown in FIG. 2 through the insertion opening 133 of the front bezel 130, the tip of the disc cartridge 13 first contacts 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
Abuts on the front surface 89 of the carrier unit 70, the disc cartridge detection switch 98 is pressed. Thereby, the control device detects that the disk cartridge 13 has been inserted into the disk device 10. When the disc cartridge 13 is in contact with the carrier unit 70, the shutter drive pin 113 provided on the shutter lever 78 engages with the end of the shutter 15 provided on the disc cartridge 13.

When it is detected that the disk cartridge 13 has been inserted into the disk device 10, the control device starts applying a voltage to the loading motor 100. At this time, even when the disk cartridge 13 is inserted, the control device keeps the loading motor 100 at half the normal driving voltage (E) while the carrier unit 70 moves from the position shown in FIG. 2 to the position shown in FIG. Voltage (E /
2) is applied to improve the operability when the disc is inserted. That is, the carrier unit 70 moves in the arrow Y1 direction while being pressed by the insertion operation of the disc cartridge 13 while being assisted by the driving force of the loading motor 100. Therefore, the operator can insert the disc cartridge 13 with a relatively small operation force. 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 D start position), and is indicated by P3 in the figure.

When the carrier unit 70 is at the ejection position P
When moving from 1 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
Is moved 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 back 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 disk lever 6
0 means that the position when the carrier unit 70 is at the ejection position P1 is maintained, and the disk lever 60 does not hinder the insertion of the disk cartridge 13.

On the other hand, the carrier unit 70 starts moving from the ejection position P1 in the direction of the arrow Y1 in FIG.
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 toward the DL start position P3 from the position P2, 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 retraction cam 54, and the cartridge lever 77 moves in the arrow Y1 direction while rotating clockwise by the urging force of the coil spring 108. Accordingly, the cartridge lever 77 is biased by the coil spring 108 and rotates clockwise about the shaft 105 along the right rail 50. 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 counterclockwise. 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. .

As a result, the shutter lever 78
As shown in FIG. 8, the shutter 15 that rotates counterclockwise and engages with the shutter drive pin 113
The lid is opened by sliding in two directions. When the shutter 15 is completely opened, the shutter drive pin 113 is disengaged from the slit 126 as described above, and
Engages with the hemispherical projection 116 of the leaf spring 79, thereby restricting the movement of the shutter lever 78.

As described above, in the disk device 10, the cartridge lever 77 of the carrier unit 70 grips the disk cartridge 13 inserted at the insertion position and conveys it to the mounting position, or moves the disk cartridge 13 at the mounting position to the insertion position. Eject. Then, a shutter lever 7 swingably provided on the carrier unit 70 is provided.

The movement of the disk cartridge 13 engaged with the cartridge lever 77 is automatically conveyed in the direction of the arrow Y1 in FIG. Then, as shown in FIG. 19, when the center hole 14a of the DVD-RAM 14 mounted on the disc cartridge 13 is transported to a position where the turntable 24 is coincident with the turntable 24, the control device controls the loading motor 10
The rotation of the carrier unit 70 is stopped by stopping the rotation of 0. At this time, the projection 116 of the leaf spring 79 is engaged with the engagement hole 111 of the shutter lever 78 in a state where the shutter 15 of the disk cartridge 13 is displaced to the open position, and the shutter lever 78 is locked. Since the shutter drive pin 113 that fits into the long hole 112 of the 78 is disengaged from the slit 126, the disk cartridge 13 can be easily transported even with a slot-in type configuration, and the loading motor 100 that drives the carrier unit 70 The size can be reduced.
In the following description, the position of the carrier unit 70 where the center hole 14a of the DVD-RAM 14 and the turntable 24 coincide with each other is called a disk cartridge loading completion position (abbreviated as DL completion position), which is indicated by P6 in the figure. And This DL completion position P6 is shown in FIG.
This is the same position as the 12L retreat position P6 shown in FIG. The position of the disk cartridge 13 at this time is referred to as a loading position.

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.

When the disk cartridge 13 is transported to the DL completion position P6 as described above, the control device drives the above-described slide motor (not shown) 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.

Therefore, the DVD-RAM 14 provided in the disk 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,
-Reproduction / recording processing can be performed on the RAM 14.

When the disk cartridge 13 is ejected from the disk device 10, the operation is the opposite of the operation at the time of mounting described above, 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 ejection operability. Configuration.
