The present invention relates to a disk device in which various disks such as a CD (compact disk), a DVD (digital versatile disk), a CD-ROM, and a CD-RAM are loaded, and in particular, a transport roller for transferring the disk is provided. The present invention relates to a disk device.
[0002]
[Prior art]
In a disk device, a conveyance roller is provided between an insertion / discharge port provided in the apparatus main body or a disk storage unit in which a plurality of disks are stored and a disk drive unit. The disc is transferred between the insertion / ejection port or the disc storage portion and the disc driving portion.
[0003]
[Problems to be solved by the invention]
However, if the distance between the insertion / ejection port and the transport roller is large, the tip of the disk inserted from the insertion / ejection port may come off the transport roller, and the disc cannot be reliably transported by the transport roller. is there.
In addition, in a disk device in which a large-diameter disk having a diameter of 12 cm is inserted, in order to convey the large-diameter disk inserted from the insertion / ejection port by the conveyance roller and to be loaded into the disk drive unit, A certain distance is provided between the transport roller and the disk drive unit. As a result, when a small-diameter disk having a diameter of 8 cm is inserted, the small-diameter disk conveyed by the conveying roller may not be reliably fed to a position where it can be positioned on the disk drive unit.
[0004]
In addition, one of the disks is selected from the disk storage unit in which a plurality of disks are stored, and is transported to the disk drive unit by the transport roller. The disk storage unit stores a large diameter disk and a small diameter disk. In some cases, if the conveying roller is arranged to convey a large-diameter disk, the small-diameter disk may not be fed to the disk drive unit.
[0005]
The present invention solves the above-described conventional problems, and transports a disc inserted from the insertion / ejection port or a disc stored in the disc storage unit even if the distance between the insertion / ejection port and the transport roller is long. An object of the present invention is to provide a disk device that can be securely clamped by a roller.
[0006]
It is another object of the present invention to provide a disk device that can reliably transport even a small-diameter disk to a disk drive unit.
[0007]
[Means for Solving the Problems]
The present invention relates to a disk device in which a conveying roller for sandwiching a disk and a facing member are provided on a disk transfer path in the apparatus body.
A drive member for moving the transport roller in the disc transfer direction while holding the disc. And a power transmission device that continues to rotationally drive the transport roller in the disk transport direction when the transport roller is moved in the disk transport direction by the drive member, and the transport roller rotates. While moving in the disk transfer direction, the disk continues to be held between the transport roller and the opposing member. It is characterized by this.
[0008]
In the disk device of the present invention, the transportable roller moves between the insertion / ejection port and the disk drive unit or between the disk storage unit and the disk drive unit, thereby substantially extending the distance that the disk can be transferred.

Therefore, for example, in a disk device that transports a large-diameter disk having a diameter of 12 cm, a small-diameter disk having a diameter of 8 cm can be reliably transported toward the disk drive unit or the disk storage unit. The disc to be transported may be stored in a hard case, such as a mini disc (MD).
[0009]
In this case, the opposing member is an opposing pad or opposing roller that moves together with the conveying roller. With the conveying roller stopped, the disk is sandwiched between the conveying roller and the opposing member and moved by a predetermined distance. Alternatively, after this movement is completed, the conveying roller may be started to transfer the disk.
[0011]
The transport roller rotates during movement, so that the disk can be transported quickly.
[0013]
In this case, the opposing member is formed of a material having a small coefficient of friction with the disc such as a synthetic resin, and the disc is slid and transferred with the opposing member when the transport roller moves.

[0027]
In the region immediately inside the insertion / discharge port 2, the upper chassis is provided with a transport means III.
The transport means III is provided with a transport roller 21. The conveying roller 21 is formed of a material having a large friction coefficient such as rubber fixed to the outer periphery of the roller shaft 21a. As shown in FIG. 1, the roller shaft 21a of the roller 21 is supported by an arm 23a. A base end portion of the arm 23a is rotatably supported with respect to the upper chassis via a support shaft 24a. As shown in FIG. 5, the arm 23 a is urged clockwise by the torsion spring 13.
[0028]
FIG. 5 is a side view showing in detail the support structure of the transport roller 21, and FIGS. 6A and 6B are side views showing the structure of a drive member that moves the transport roller 21.
As shown in FIG. 5, an elongated hole 23b is formed in the arm 23a along the length direction, and the roller shaft 21a is slidably inserted into the elongated hole 23b. Further, a tension spring 25 is applied as a biasing member between the roller shaft 21a and the support shaft 24a, and the roller shaft 21a and the transport roller 21 are biased in the direction of the support shaft 24a.
[0029]
As shown in FIG. 5, a guide hole 4 is opened in a side plate of the lower chassis 3 that serves as a fixed portion. The guide hole 4 has an inclined guide portion 4a and a horizontal guide portion 4b extending in the X1-X2 direction. And are formed. The roller shaft 21 a is inserted into the guide hole 4. Therefore, the roller shaft 21a that is pulled in the direction of the support shaft 24a by the tension spring 25 is urged in a direction in which the roller shaft 21a contacts the inclined guide portion 4a and the horizontal guide portion 4b.
[0030]
As shown in FIGS. 6A and 6B, a driving member 31 is supported on the side plate of the lower chassis 3 so as to be linearly reciprocable in the X1-X2 direction, and this driving member 31 is not shown. It is reciprocated in the X1-X2 direction by the power of the motor.
An elongated hole is formed in the drive member 31, and the roller shaft 21a is inserted into the elongated hole. This long hole is comprised from the vertical guide part 32a extended in a perpendicular direction (Z1-Z2 direction), and the circular arc guide part 32b continuous to the lower end of this vertical guide part 32a. As shown in FIG. 6B, when the drive member 31 has moved most in the X1 direction, the arc guide portion 32b is located on an arc locus centering on the support shaft 24a.
[0031]
A drive arm 33 is rotatably provided on the drive member 31 by a support pin 34. As shown in FIG. 6A, normally, the drive arm 33 is located away from the vertical guide portion 32a. As shown in FIG. 6B, when the drive arm 33 is driven clockwise by a switching mechanism (not shown) after the drive member 31 has moved most in the X1 direction, the roller shaft 21a is pushed by the drive arm 33, The roller shaft 21a moves along the arc guide portion 32b, and the arm 23a is rotated counterclockwise so as to face the urging force of the torsion spring 13.
[0032]
As shown in FIG. 6A, when the drive member 31 is moving in the X2 direction, the roller shaft 21a is positioned above the vertical guide portion 32a, and the arm 23a is rotated counterclockwise. . Further, the roller shaft 21 a receives the pulling force of the pulling spring 25 and is in contact with the inclined guide portion 4 a of the guide hole 4. As shown in FIG. 1, the position of the transport roller 21 at this time is in a standby position {circle around (3)} just inside the insertion / discharge port 2 and above the transport surface (transport path) L of the disk D.
[0033]
When the driving member 31 moves in the X1 direction from the position of FIG. 6A, the roller shaft 21a is pushed by the vertical guide portion 32a, and the arm 23a is rotated clockwise by the torsion spring 13. At this time, the roller shaft 21a inserted into the guide hole 4 formed in the lower chassis 3 moves while descending in the Z2 direction along the inclined guide portion 4a and reaches the horizontal guide portion 4b. At this time, as shown in FIG. 2, the transport roller 21 is in a clamping position {circle around (4)} where the disk D can be clamped by a counter pad 26 described later.
[0034]
When the drive member 31 moves in the X1 direction as it is, the roller shaft 21a is moved along the horizontal guide portion 4b of the guide hole 4. Therefore, the transport roller 21 moves in the X1 direction along the counter pad 26, that is, while maintaining the state in which the disk D can be clamped with the counter pad 26, and as shown in FIG. When most moved in the direction, the conveying roller 21 moves to the movement end position (5) shown in FIG.
[0035]
When the drive arm 33 rotates clockwise in the state of FIG. 6B, the roller arm 21a is pushed by the drive arm 33 and moves along the arc guide portion 32b. As a result, the arm 23a rotates counterclockwise, and the transport roller 21 moves to the retracted position (6) away from the opposing pad 26 and the disk D as shown in FIG. When the drive arm 33 rotates counterclockwise, the conveying roller 21 returns from the retracted position (6) to the movement end position (5) by the urging force of the torsion spring 13 shown in FIG.
[0036]
6B, when the drive member 31 is moved in the X2 direction without operating the drive arm 33, the transport roller 21 located at the movement end position (5) is moved along the opposing pad 26. Then, it moves in the X2 direction, and further returns to the standby position (3) as shown in FIG.
In the transport means III, the counter pad (opposing member) 26 for sandwiching the disk D with the transport roller 21 is provided. As shown in FIGS. 2 to 4, the counter pad 26 is made of a resin material having a small friction coefficient. Further, the length of the counter pad 26 in the X direction is formed such that the disk D is continuously clamped with the transport roller 21 while the transport roller 21 moves from the clamping position (4) to the movement end position (5). ing.
[0037]
The counter pad 26 is connected to a pair of links 28a and 28b by shafts 27a and 27b, and the links 28a and 28b are rotatable by shafts 29a and 29b on a support body (not shown) provided on the upper chassis. It is supported by. Therefore, the counter pad 26 moves in a substantially parallel posture. This movement is interlocked with the rotational movement of the arm 23a supporting the transport roller 21, and the opposing pad 26 is moved to the standby position (7) in FIG. 1 and the transport position (8) shown in FIGS. , And moves between the three positions of the retracted position (9) shown in FIG.
[0038]
7A and 7B show a structure for transmitting power to the transport roller 21 in the transport means III, and are side views equivalent to FIG.
In this power transmission device, a roller gear 41 is fixed to the roller shaft 21a of the transport roller 21, so that the transport roller 21 and the roller gear 41 can rotate together. A conveyance motor Mt is provided on a side plate of the upper chassis, a fixed shaft 43 is provided on a side of the conveyance motor Mt, and a driving gear 44 is provided on the fixed shaft 43. The pinion gear 42 fixed to the output shaft of the transport motor Mt and the drive gear 44 are always meshed with each other.
[0039]
A planetary gear 45 meshes with the drive gear 44, and both ends of the link 47 are rotatably supported by the shaft 46 and the fixed shaft 43, respectively. The planetary gear 45 is engaged with a connecting gear 48, and both ends of the link 51 are rotatably connected to the shaft 49 and the shaft 46 of the planetary gear 45, respectively. Accordingly, the drive gear 44, the planetary gear 45, and the connecting gear 48 can change their relative positions while being engaged with each other.
The shaft 49 of the connecting gear 48 is guided by a guide portion 52 provided on the side plate of the lower chassis 3 and is only between the position shown in FIG. 7A and the position shown in FIG. It can be moved horizontally in the direction. Further, the link 47 is urged counterclockwise by a spring 53 which is an urging member, and by this urging force, the shaft 49 of the connecting gear 48 is always urged toward the end portion of the guide portion 52 on the X2 side. Has been.
[0040]
When the conveying roller 21 is at the standby position (3) shown in FIGS. 1 and 6A, the roller gear 41 provided on the roller shaft 21a is separated from the connecting gear 48 at the position shown in FIG. 7A. Yes. When the conveying roller 21 reaches the clamping position (4) shown in FIGS. 2, 6 (A) and 7 (A), the roller gear 41 meshes with the connecting gear 48. While the conveying roller 21 is moved to the movement end position (5) shown in FIGS. 3 and 7B by the moving force of the driving member 31 as it is, the roller gear 41 and the connecting gear 48 are connected to the spring 53 and the torsion spring. The coupling gear 48 linearly moves in the X1 direction along the guide portion 52 so as to be engaged with the urging force of 13 and pushed by the roller gear 41 moving in the X1 direction. During this time, the planetary gear 45 moves around the drive gear 44 as a planet.
[0041]
Accordingly, the transport roller 21 can be rotationally driven by the transport motor M while the transport roller 21 moves in the X1 direction and the X2 direction between the clamping position (4) and the movement end position (5).
Also, as shown in FIGS. 4 and 6B, when the conveying roller 21 moves to the retracted position (6), the roller gear 41 is separated from the connecting gear 48.
[0042]
The overall operation of the disk device will be described below.
In this disk device, the disks D are inserted one by one from the insertion / discharge port 2 and discharged one by one. Therefore, the transport position of the disk is always the height position where the insertion / ejection port 2 is formed.
When the disk D is inserted from the insertion / ejection port 2, a vacant storage area in the disk storage unit I is selected in the state shown in FIG.
[0043]
In the selection operation in the state of FIG. 1, in the disk storage portion I, the holding bracket 7 holding the base end portion of each support 6 is guided by the guide shafts 9 and 9 and moved up and down in the Z1-Z2 direction. Thus, the support 6 that forms the storage area into which the disk is to be sent is selected. That is, when the support body 6 moves up and down in the Z1-Z2 direction and reaches the height position of the transport surface L, the up-and-down movement of the holding bracket 7 stops.
[0044]
In this selection operation, as shown in FIG. 1, the restriction member 55 is fixed on the upper side and the restriction member 56 is fixed on the lower side so that the disk D held on the support body 6 does not come out from the support body 6 in the X2 direction. When the holding bracket 7 moves up and down, the restricting members 55 and 56 enter the restricting hole formed in the support 6 and the center hole Da of the disc D, and the disc D is prevented from coming out in the X2 direction. The However, the regulating members 55 and 56 are spaced apart from each other in the vertical direction, and the disk D moving on the transport surface L passes through the gap between the regulating members 55 and 56.
[0045]
In the selection operation shown in FIG. 1, the disk drive unit II is in the standby position {circle around (1)} moved to the side opposite to the disk storage portion I, that is, the inside of the insertion / ejection port 2. Further, both the transport roller 21 and the counter pad 26 constituting the transport means III are located at standby positions {circle around (3)} and {circle around (7)} that overlap above the disk drive unit II.
In this disk apparatus, the disk drive unit II and the transport means III are overlapped with each other to be a standby position that does not interfere with the disk D. Therefore, for example, in a compact structure configured in the 1 DIN size housing 1, when the selection operation is performed by raising and lowering the disk storage portion I, the selection operation is not hindered by the disk drive unit II and the transport means III. .
[0046]
Hereinafter, the operation of feeding the disc D to the area on the support 6 at the third stage (iii) from the top of the disc storage portion I will be described.
As described above, the holding bracket 7 is moved up and down, and the holding bracket 7 is stopped when the third stage (iii) support body 6 reaches almost the same height as the conveying surface L.
Here, using a selection means (not shown), the two supports, the uppermost support (i) 6 and the second support (6) 6 are lifted upward with the support shaft 8 as a fulcrum. The lower stage (iv) support body 6 is also rotated downward with the support shaft 8 as a fulcrum, and an interval (space) is formed above and below the third stage (iii) support body 6.
[0047]
Next, as shown in FIG. 2, the disk drive unit II is moved in the X1 direction to the drive position (2).
After the disk drive unit II moves to the drive position {circle around (2)} or simultaneously with the movement, the drive member 31 at the position shown in FIG. 6 (A) is driven in the X1 direction, and the arm 23a moves the support shaft 24a. It is rotated clockwise as a fulcrum, and the roller shaft 21a is guided by the inclined guide portion 4a, so that the conveying roller 21 is moved to the clamping position (4). At the same time, the opposing pad 26 moves in parallel and moves to the transport position (8). In FIG. 2, the conveyance roller 21 is in the clamping position (4), and the disk D can be clamped between the conveyance roller 21 and the opposing pad 26 at a position close to the insertion / ejection port 2.
[0048]
When the disk D is inserted from the insertion / ejection port 2, the insertion of the disk is detected by a detection means (not shown), and in the state of FIG. 2, the transport motor Mt is started and the transport roller 21 starts to rotate counterclockwise. . Therefore, the disk D inserted from the insertion / discharge port 2 is sandwiched between the transport roller 21 and the opposing pad 26 at the sandwiching position (4), and the rotational force of the transport roller 21 causes the disk D to be transported in the X1 direction. Be started.
Until the detection means (not shown) detects that the disk D has been sent to a predetermined position in the X1 direction, the conveying roller 21 stops at the clamping position (4) in FIG. 2, and continues to rotate at that position.
[0049]
When it is detected by the detection means that the disk D has moved a predetermined distance in the X1 direction, the drive member 31 starts to move in the X1 direction, and the drive member 31 moves to the position shown in FIG. Stop. Accordingly, the transport roller 21 moves horizontally from the clamping position (4) to the movement end position (5). During this time, the transport motor Mt continues to rotate, and the transport roller 21 continues to rotate counterclockwise. Therefore, the disk D is continuously conveyed in the X1 direction by the conveying roller 21, and during this time, the conveying roller 21 moves to the movement end position (5) shown in FIG.
[0050]
In the state shown in FIG. 3, the transport motor Mt continues to rotate, and the disk D is fed onto the vacant support 6 at the third stage (iii). The disk D moving in the X1 direction passes between the turntable 12 and the clamper 16 of the disk drive unit II, and is fed onto the support 6 while being guided up and down by the turntable 12 and the clamper 16. When the end detection means (not shown) detects that the disk D is completely stored in the support 6, the transport motor Mt stops and the loading of the disk D is completed.
[0051]
In this disk carry-in operation, as shown in FIG. 2, when the disk D is inserted from the insertion / discharge port 2, the transport roller 21 approaches the insertion / discharge port 2 side to greet the disk D. The disk D inserted from the discharge port 2 is securely held between the transport roller 21 and the opposing pad 26. Further, since the distance between the insertion / discharge port 2 and the transport roller 21 is shortened, it is not necessary to dispose a guide member between the insertion / discharge port 2 and the transport roller 21.
However, when the disk D is fed in the X1 direction while the transport roller 21 is stopped at the clamping position (4) shown in FIG. 2, X2 of the disk D is not yet inserted before the disk D is completely inserted into the support 6. The end on the side is detached from the transport roller 21. However, in this disk apparatus, the transport roller 21 transporting the disk D moves to the movement end position (5) on the X1 side as shown in FIG. Can do.
[0052]
Further, when the disk is fed onto the other support 6 in the disk storage section I, the disk drive unit II and the transport means III once return to the state shown in FIG. 1, and then the disk storage section I is raised and lowered, The support 6 into which the disc is to be sent is selected. Thereafter, the state shown in FIG. 2 is obtained, and the disk D can be inserted. Then, the state shifts to the state shown in FIG.
[0053]
When any of the disks in the disk storage unit I is ejected, the disk storage unit I moves up and down with the disk drive unit II and the transport means III shown in FIG. 1, and the disk to be ejected is selected. . After the disk D is selected and the support 6 positioned above and below it rotates upward and downward, the disk drive unit II moves in the X1 direction to reach the drive position (2). Thereafter, the drive member 31 moves in the X1 direction from the position shown in FIG. 6A. At this time, the drive member 31 moves to the position shown in FIG. 6B without stopping midway. Therefore, the transport roller 21 moves to the movement end position (5) shown in FIG. 3, and the end on the X2 side of the disk D to be ejected in the disk storage portion I is held between the transport roller 21 and the counter pad 26. Is done.
[0054]
Then, the transport motor Mt is started and the transport roller 21 starts to rotate clockwise. The disk D is sent out in the X2 direction by this rotation, but when the detecting means (not shown) detects that the disk D has been transported in the X2 direction by a predetermined distance, the drive member 31 located at the position of FIG. The transfer roller 21 starts to move in the X2 direction and moves in the X2 direction while rotating. When the conveying roller 21 reaches the clamping position (4) shown in FIG. 2, the driving member 31 stops. The conveyance roller 21 continues to rotate at the clamping position (4), and the disk D is discharged from the insertion / discharge port 2.
[0055]
The transport motor Mt stops when the end of the disk D on the X1 side is sandwiched by the transport roller 21 at the sandwiching position (4). Therefore, the disk D protruding from the insertion / discharge port 2 stops at a position sandwiched between the transport roller 21 and the opposing pad 26, and then the disk D is pulled out by hand. At this time, since the transport roller 21 comes close to the insertion / ejection port 2 and stops, the protruding amount of the disk D from the insertion / ejection port 2 can be lengthened, and it is easy to grasp it by hand. In particular, when the insertion of a small-diameter disk having a diameter of 8 cm is enabled, the small-diameter disk is sufficiently inserted from the insertion / discharge port when the conveyance roller 21 is stopped by moving the conveyance roller 21 in the X2 direction and stopping it. It will stop at the protruding position.
[0056]
Next, the operation of selecting a disk in the disk storage unit I and loading it into the disk drive unit II will be described.
At this time, in the state of FIG. 1, the disk storage portion I is moved up and down to select a disk to be driven. The subsequent operation is the same as the discharging operation. That is, after the support bodies 6 positioned above and below the selected disk are respectively rotated up and down, the disk drive unit II moves in the X1 direction. At this time, the clamper 16 passes above the selected disk D and the turntable 12 passes below, so that the disk drive unit II reaches the drive position (2).
[0057]
Thereafter, the drive member 31 moves from the position shown in FIG. 6A to the position shown in FIG. 6B, and the conveying roller 21 moves to the movement end position (5) shown in FIG. Since the X2 side end of the selected disk D, for example, the third stage (iii) disk D slightly protrudes from the disk drive unit II in the X2 direction, the X2 side of the third stage disk D Is sandwiched between the transport roller 21 and the opposing pad 26.
Thereafter, when the transport roller 21 is driven to rotate clockwise by the power of the transport motor Mt, the disk D sandwiched between the transport roller 21 and the opposing pad 26 is sent out in the X2 direction by the rotational force of the transport roller 21. It is. When the center hole Da of the disk D substantially coincides with the rotation center of the turntable 12, the transport roller 21 stops.
[0058]
Next, as shown in FIG. 4, the support body 6 supporting the third-stage (iii) disk D, which has been in a substantially horizontal position, is pivoted downwardly so that the support body 6 is in the third-stage ( iii) Move away from the lower surface of the disk D. At substantially the same time, the drive arm 33 shown in FIG. 6B rotates clockwise, the conveying roller 21 is guided by the arc guide portion 32b to reach the retracted position (6), and the opposing pad 26 is raised. To the retreat position {9}. Then, in the disk drive unit II, the clamper 16 is lowered, and the center hole Da of the third-stage disk D in the free state is clamped by the turntable 12 and the clamper 16.
[0059]
The clamped disc D is rotated by the power of the spindle motor Ms. Further, in the disk drive unit II, the optical head is moved by the thread motor, and the reading operation or writing operation on the recording surface of the disk D is performed.
When the drive of the disk D is completed, the state returns to the state shown in FIG. That is, the clamper 16 is raised and the clamp of the disk D is released. Further, the third stage (iii) support body 6 rotates counterclockwise from the state of FIG. 4 to reach the position of FIG. 3 to support the disk D from below, and at substantially the same time, the transport roller 21 and the opposing pad 26 It reaches the movement end position (5) and the transfer position (8). Then, the disk D is fed in the X1 direction by the rotational force of the transport roller 21 at the movement end position (5), and is held on the third stage support 6.
[0060]
Thereafter, when another disk D is selected, as shown in FIG. 2, the disk drive unit II returns to the standby position {circle around (1)}, and the transport roller 21 and the opposing pad 26 also move to the standby positions {circle around (3)} and {circle around (7)}. Return. In this state, when the holding bracket 7 and each support body 6 are moved up and down to newly select a disk and the next selected disk D substantially coincides with the transport surface L, the same as described above. Then, the disk D is pulled out, clamped and driven.
[0061]
【The invention's effect】
As described above, in the present invention, since the transport roller moves along the transport direction of the disk, it is easy to sandwich the disk to be transported by the transport roller, and the disk is securely attached to the disk drive unit and the disk storage unit. It can be sent.
