Description

  The present invention relates to a disk drive device that records and / or reproduces signals on and from an optical disk, and more particularly to a slot-in type disk drive device and electronic equipment.

  Conventionally, optical disks such as CD (Compact Disk) and DVD (Digital Versatile Disk) and magneto-optical disks such as MO (Magneto optical) and MD (Mini Disk) have been widely known as optical disks. Various disk drive devices corresponding to the above have appeared.

  In the disk drive, the lid or door provided on the housing is opened, the disk is directly mounted on the turntable facing from the door, and the disk is placed on the disk tray that is horizontally removed from the housing. There are a type in which a disc is automatically mounted on an internal turntable when the disc tray is pulled in, a type in which a disc is directly mounted on a turntable provided in the disc tray, and the like. However, both types require operations such as opening and closing the lid and door, inserting and removing the disc tray, and loading the disc on the turntable.

  On the other hand, there is a so-called slot-in type disk drive device in which a disk is automatically mounted on a turntable simply by inserting the disk from a slot provided on the front surface of the housing. In this disk drive device, when a disk is inserted from the slot, the pair of guide rollers are inserted from the slot by rotating the pair of guide rollers in opposite directions while sandwiching the disk between the pair of guide rollers facing each other. A loading operation for drawing the disk into the housing and an ejecting operation for ejecting the disk from the slot to the outside of the housing are performed.

  By the way, mobile devices such as notebook personal computers on which a disk drive device is mounted are required to be further reduced in size, weight, and thickness, and the accompanying demand for reduction in size, weight, and thickness of the disk drive device is also increasing. In recent years, there has been an increasing demand for slot-in type disk drive devices having a better operational feeling than tray type disk drive devices that have been mainstream in personal computers and the like.

  However, in the slot-in type disk drive device, since the length of the pair of guide rollers described above is longer than the diameter of the disk, the overall width of the device becomes longer. Further, since the disk is sandwiched between the pair of guide rollers, the dimension in the thickness direction is also increased. For this reason, the conventional slot-in type disk drive device is very disadvantageous for miniaturization and thinning.

  In particular, an ultra-thin disk drive device mounted on a notebook personal computer or the like has a standard thickness of 12.7 mm, and further up to 9.5 mm, which is the same thickness as a hard disk drive (HDD) unit. When the thickness is reduced, it is difficult to divert such a guide roller as it is.

Therefore, in the slot-in type disk drive device, in order to meet the demand for downsizing and thinning, a plurality of rotations are performed between the disk inserted from the slot and the base to which the turntable to which the disk is mounted is attached. A moving arm is disposed, and while the rotating arms are rotated in a plane parallel to the disk, a loading operation for pulling the disk from the slot into the inside of the housing, and a disk is ejected from the slot to the outside of the housing. A disk drive device that performs an ejection operation has been proposed (see, for example, Patent Document 1).
JP 2002-117604 A (paragraphs [0018] to [0028], FIG. 1) Japanese Patent Laid-Open No. 7-220353 (paragraph [0049], FIG. 6)

  However, in the technique of Patent Document 1, for example, when a slot-in type disk drive device is used as a vehicle-mounted disk drive device, the disk is ejected from the slot by about 6 cm until the center hole of the disk comes out, and then for a certain time. If the user does not remove the disk when the time has elapsed, the disk may fall out of the slot due to vibration or the like. For this reason, there is a desire to be able to redraw the disc, but in order to draw the disc once ejected, the disc must be pushed in by about 10 cm, for example. Many slot-in type disk drive devices for consumers use a disk when the user inserts the disk into the slot by about 5 to 6 cm. Therefore, when it is necessary to insert about 10 cm, there is a possibility that the user feels uncomfortable.

  Further, the technique disclosed in Patent Document 2 includes a guide roller for transporting the disk while sandwiching the upper surface and recording surface of the disk near the slot. Therefore, it is not necessary to insert the disk, for example, about 10 cm in order to pull the disk inserted into the slot. However, since a mechanism for moving the guide roller up and down is required to release the disk from the guide roller, there is a problem that the size of the apparatus is large.

  In view of the circumstances as described above, an object of the present invention is to allow a recording medium to be drawn from the slot side to the mounting portion side without depending on the position of the recording medium in the slot and to be miniaturized. To provide equipment.

  In the present invention, since the recording medium is provided with the first transport mechanism capable of drawing the recording medium from the slot side to the mounting portion side, the recording medium is moved to the mounting portion side without depending on the position of the recording medium in the slot. You can pull in. Further, the recording medium drawn from the first transport mechanism to the mounting portion side is transported to the mounting position by the mounting portion by the second transport mechanism, whereby the recording medium is released from the first transport mechanism. As a result, for example, a mechanism for moving the first transport mechanism in a direction perpendicular to the recording surface of the recording medium in order to release the recording medium from the first transport mechanism becomes unnecessary, and the disk drive device can be made smaller (thin). Can be planned.

  According to an aspect of the present invention, it further includes a detection unit for detecting whether or not the recording medium is inserted into the slot. Accordingly, when the detection unit detects that the recording medium is inserted into the slot, the recording medium can be drawn to the mounting unit side by the first transport mechanism.

  According to an aspect of the present invention, the first transport mechanism has a roller provided so as to rotate in contact with a recording surface of the recording medium or an opposite surface thereof, and the roller A rotation driving mechanism for driving the rotation; and a guide member for guiding the recording medium between the rollers. Accordingly, the recording medium in the slot can be stably pulled to the mounting portion side by rotating the roller by the rotation driving mechanism while the recording medium is sandwiched between the roller and the guide member.

  According to an embodiment of the present invention, the second transport mechanism includes a side roller provided to rotate in contact with the side surface of the recording medium, and rotatably supports the side roller. A lever member that can rotate, a rotation mechanism that rotates the lever member while the side roller presses the side surface of the recording medium, and the side surface of the recording medium in cooperation with the rotating lever member. And an arm for transporting the recording medium while being held. Accordingly, the recording medium in the slot can be pulled in a state where the side surface of the recording medium is sandwiched by the arm while the side roller is pressed against the side surface of the recording medium by rotating the lever member.

  “Cooperating” means a case where the time periods of operation of both (for example, the lever member and the arm) overlap. Or the time zone of the said operation | movement includes the case where it operate | moves sequentially without overlapping.

A mechanism and a guide member that guides the recording medium by sandwiching the recording medium between the side rollers. Accordingly, the recording medium in the slot can be pulled in without damaging the recording surface of the recording medium by rotating the side roller by the rotation driving mechanism in a state where the side surface of the recording medium is sandwiched between the side roller and the guide member. it can. In the invention according to claim 4, the “side roller” is a member of the “second transport mechanism”. However, in the present invention according to claim 5, the “side roller” is the “first transport mechanism”. It is a member having.

  According to an embodiment of the present invention, the second transport mechanism is rotatably provided, the lever member rotatably supporting the roller, and the roller pressing the side surface of the recording medium while the roller presses the side member. A rotation mechanism for rotating the lever member. The “lever member” is a member that the “second transport mechanism” has. That is, since the “side roller” is supported by the “lever member”, the side roller pulls the recording medium toward the mounting portion side by the positive driving of the rotation driving mechanism, and the rotation mechanism actively By driving, the lever member is rotated and the recording medium can be conveyed to the mounting position. That is, the work performed in cooperation between the first transport mechanism and the second transport mechanism becomes smooth. In this case, while the lever member is rotated by the driving of the rotation mechanism, the rotational driving of the side roller by the rotation driving mechanism may or may not be performed. When the side roller is not actively driven by the rotation driving mechanism, the lever member and the side roller are relatively rotated by the frictional resistance between the side roller and the side surface of the recording medium.

  According to an aspect of the present invention, it further includes a detection unit for detecting whether or not the recording medium is inserted into the slot. Accordingly, when the detection unit detects that the recording medium is inserted in the slot, the lever member is rotated to press the side roller against the side surface of the recording medium, and the slot is cooperated with the side roller. The recording medium inside can be pulled in.

  According to an embodiment of the present invention, the second transport mechanism includes an arm for transporting the recording medium while sandwiching a side surface of the recording medium, and the guide member includes the side roller.

The recording medium can be pulled in.

  According to an embodiment of the present invention, the guide member is provided in the casing so as to extend in a direction in which the recording medium is drawn by the side roller. As a result, the side roller of the recording medium is pressed against the side surface of the recording medium by rotating the lever member, and the side surface of the recording medium is sandwiched between the side roller and the guide member by rotating the side roller. The recording medium can be drawn in the extending direction.

  The inventions according to claims 6 to 9 described above are supported as a second embodiment or a third embodiment described later.

A lever member that conveys the recording medium; and a conveyance member that conveys the recording medium to a mounting position by the mounting unit in cooperation with the lever member. When the diameter of the recording medium is relatively large, the lever member receives the recording medium from the first transport mechanism and transports it to the mounting portion side in cooperation with the first transport mechanism, and the transport member records in cooperation with the lever member. When the medium is transported to the mounting position by the mounting unit, the lever member reliably and stably presses the side surface of the recording medium, so that the recording medium can be transported stably. On the other hand, when the diameter of the recording medium is relatively small, for example, the lever member needs to be relayed so that the conveying member can convey the recording medium to the mounting position after the recording medium is separated from the first conveying mechanism. Therefore, in this case, it is useful that the second transport mechanism has a lever member and a transport member. The present invention according to claim 10 is supported as a first, second or third embodiment to be described later.

  According to an aspect of the present invention, the transport member is an arm for transporting the recording medium while sandwiching a side surface of the recording medium. Accordingly, the recording medium can be conveyed while the side surface of the recording medium is held by the arm in cooperation with the lever member.

  In the present invention, since the recording medium is provided with the first transport mechanism capable of drawing the recording medium from the slot side to the mounting portion side, the recording medium is moved to the mounting portion side without depending on the position of the recording medium in the slot. The recording medium that can be pulled in is transported to the mounting position by the mounting section by the second transport mechanism by releasing the recording medium from the first transport mechanism. Therefore, for example, a mechanism for moving the first transport mechanism in a direction perpendicular to the recording surface of the recording medium in order to release the recording medium from the first transport mechanism becomes unnecessary, and the disk drive device is small (thin).

Then, in a state where the first front surface side contact member 38 and the second front surface side contact member 40 are in contact with the front surface side of the outer peripheral portion of the large-diameter disk 2A, The two rotating arms 36 are urged by the torsion coil spring 71d and the second torsion coil spring 77 and are rotated in directions close to each other, that is, in the directions of arrows a ₁ and b ₁ shown in FIG.

The third rotating arm 49, by the roller 50 is pressed at the contact state to the back side of the outer peripheral portion of the large-diameter disk 2A, is rotated in the direction of the arrow d ₁ shown in FIG. 18 The Then, when the large-diameter disk 2A is pulled in at the disk mounting position shown in FIG. 18, the third rotating arm 49 is brought into contact with a restriction piece (not shown) of the second rotating arm 36. The rotation is restricted.

  Thereby, the first rotating arm 35 and the second rotating arm 36 convey the large-diameter disk 2A to the disk mounting position shown in FIG. 18 while pressing the front side of the outer peripheral portion of the large-diameter disk 2A. It will be.

  As shown in FIGS. 16 to 18 and the like, when the large-diameter disk 2A is pulled in and conveyed to the disk mounting position, the side roller 48 can stably press the side surface of the large-diameter disk 2A from the state shown in FIG. Therefore, the large-diameter disk 2A can be reliably and stably conveyed to the disk mounting position.

  On the other hand, when the small-diameter disk 2B is inserted into the slot 19 of the housing 3, first, as shown in FIG. 23, as in the case of the large-diameter disk 2A, the detection unit 111 and the small-diameter disk 2B are If the insertion is detected, the motor 302 is driven to rotate and the roller 301 is rotated so that the small-diameter disk 2B inserted into the slot 19 is illustrated. As shown in FIG. 24, the disk is pulled into the disk mounting portion 23 side. This is the role of the first transport mechanism 300.

  The first rotation arm 35 and the second rotation arm 36 of the second conveyance mechanism 34 are the first front-side contact member so as to cooperate with the operation of the first conveyance mechanism 300. The outer peripheral portion of the small-diameter disk 2B is sandwiched between 38 and the second front-side contact member 40.

  Then, when the third rotating arm 49 is rotated by a predetermined amount to the position shown in FIG. 24, for example, the detection switch SW2 provided on the circuit board 105 is pressed, whereby the drive lever by the displacement drive mechanism The slide to the back side of 52 is started.

Thus, the lever member 46 of the second transfer mechanism 34 is rotated in the direction of arrow c ₁ shown in FIG. 24. Further, the lever member 46 cooperates with the roller 301 while pressing the front surface side of the outer peripheral portion of the small-diameter disk 2B by the side roller 48 being in contact with the front surface side of the outer peripheral portion of the small-diameter disk 2B. Thus, the small-diameter disk 2B is pulled from the slot 19 into the housing 3. That is, the lever member 46 receives the small-diameter disk 2B from the first transport mechanism 300, and transports the small-diameter disk 2B to the disk mounting portion 23 side in cooperation with the first transport mechanism 300. It should be noted that while the lever member 46 is being rotated by driving the drive lever 52, the motor 302 may or may not be actively driven to rotate the roller 301.

Then, as shown in FIG. 25, until the center hole 2a of the small-diameter disk 2B is located further to the back side than the straight line connecting the first front side contact member 38 and the second front side contact member 40, When the small-diameter disk 2B is drawn into the housing 3, the first front-side abutting member 38 and the second front-side abutting member 40 move from the back side to the front side along the outer peripheral portion of the small-diameter disk 2B. And wrap around. Then, in a state where the first front surface side contact member 38 and the second front surface side contact member 40 are in contact with the front surface side of the outer peripheral portion of the small-diameter disk 2B, The rotating arm 36 is biased by the torsion coil spring 71d and the second torsion coil spring 77, and is rotated in the directions close to each other, that is, in the directions of arrows a ₁ and b ₁ shown in FIG. That is, the first and second rotating arms 35 and 36 serving as the transport members transport the small-diameter disk 2B to the mounting position of the disk mounting portion 23 in cooperation with the lever member 46. In this way, the work performed in cooperation between the first transport mechanism 300 and the second transport mechanism 34 becomes smooth.

The third rotating arm 49, by the roller 50 is pressed at the contact state to the back side of the outer peripheral portion of the small-diameter disk 2B, is rotated in the direction of the arrow d ₁ shown in FIG. 25 . Then, when the small-diameter disk 2B is pulled in at the disk mounting position shown in FIG. 26, the third rotating arm 49 is brought into contact with a regulating piece (not shown) of the second rotating arm 36, and the rotation thereof. The movement is restricted.

  As a result, the first rotating arm 35 and the second rotating arm 36 press the front surface side of the outer peripheral portion of the small-diameter disk 2B while the small-diameter disk 2B is placed in the disk mounting position (chucking position) shown in FIG. Will pull in.

  In this disk drive device 1, as shown in FIG. 19, when the first rotating arm 35 and the second rotating arm 36 pull the large-diameter disk 2A to the disk mounting position, for example, the first front surface. The large diameter disk 2A is inserted into the disk by sandwiching the large diameter disk 2A inside the side contact member 38, the first back surface contact member 39, the second front surface contact member 40, the side roller 48 and the roller 50. A centering operation for positioning to the mounting position is performed. That is, the center hole 2a of the large diameter disk 2A and the engagement protrusion 28a of the turntable 23a are made to coincide with each other in the direction orthogonal to the recording surface of the large diameter disk 2A.

  This centering operation is not limited to this, and as shown in FIG. 19, for example, the large-diameter disk 2A is moved so that the first back contact member 39, the side roller 48, and the roller 50 have three vertices. You may make it carry out by pinching similarly. On the other hand, as shown in FIG. 26, the centering operation of the small-diameter disk 2B is performed by, for example, the first front-side contact member 38, the first back-side contact member 39, the second front-side contact member 40, and the third. This is similarly performed by sandwiching the small-diameter disk 2B inside a roller 50a used for centering the small-diameter disk 2B provided on the rotating arm 49.

  Next, in the disk drive device 1, after the centering operation of the large-diameter disk 2A and the small-diameter disk 2B, the base elevating mechanism 55 raises the base 27, whereby the large-diameter disk 2A and the small-diameter positioned at the disk mounting position. A chucking operation for mounting the disk 2B on the turntable 23a of the disk mounting portion 23 is performed.

  Specifically, when the base 27 is raised from the chucking release position shown in FIG. 13 to the chucking position shown in FIG. 14 by the base lifting mechanism 55, the large-diameter disk 2A or the small-diameter disk 2B positioned at the disk mounting position. While the engagement protrusion 28a enters the center hole 2a, the periphery of the center hole 2a of the large-diameter disk 2A or the small-diameter disk 2B is pressed against the contact protrusion 7 of the top plate part 5a. Is engaged with the center hole 2a of the large-diameter disk 2A or the small-diameter disk 2B, and the plurality of locking claws 28b are engaged around the center hole 2a of the large-diameter disk 2A or the small-diameter disk 2B. The large diameter disk 2A or the small diameter disk 2B is held on the turntable 23a. Then, with the large-diameter disk 2A or the small-diameter disk 2B being held on the turntable 23a, the base 27 is lowered to the intermediate position shown in FIG.

Further, in the disk drive device 1, after the chucking operation, as shown in FIGS. 20 and 27, the first rotation arm 35 and the second rotation are interlocked with the slide of the drive lever 52 to the back side. The moving arm 36 is slightly rotated in the direction away from each other, that is, in the directions of arrows a ₂ and b ₂ shown in FIGS. At this time, the third rotating arm 49 is rotated integrally with the second rotating arm 36 while being in contact with a regulating piece (not shown). Further, the lever member 46, in conjunction with the slide to the rear side of the driving lever 52 is slightly rotated in the direction of arrow c ₂ shown in FIGS. 20 and 27.

  Thereby, from the outer peripheral part of the large diameter disk 2A or the small diameter disk 2B held by the turntable 23a, the first front surface side contact member 38, the first back surface side contact member 39, the second front surface side. The contact member 40, the side roller 48, and the roller 50 are in a separated state.

  In this disk drive device 1, when a recording or reproduction command is sent from the drive control circuit from the state shown in FIGS. 20 and 27, a signal is sent to the large-diameter disk 2A or the small-diameter disk 2B based on this command. Is recorded or reproduced. Specifically, the spindle motor 24a rotates the large-diameter disk 2A or the small-diameter disk 2B integrally with the turntable 23a, and the optical pickup 25 is moved from the outer peripheral side to the inner peripheral side by the pickup feeding mechanism 26, thereby focusing. When servo control and tracking servo control are applied, the TOC data recorded in the lead-in area of the large-diameter disk 2A or small-diameter disk 2B is read. Thereafter, when a signal is recorded, the optical pickup 25 moves to a predetermined address in the program area of the large diameter disk 2A or the small diameter disk 2B based on the read TOC data. When the signal is reproduced, the optical pickup 25 moves to an address in the program area where the designated data is recorded. The optical pickup 25 performs a signal writing or reading operation on a desired recording track of the large diameter disk 2A or the small diameter disk 2B.

  In the disk drive device 1, when an eject button 21 provided on the display unit 20 is pressed or an eject command is sent from the personal computer to the disk drive device 1, first, based on this command, the displacement The drive mechanism 52 starts to slide the drive lever 52 toward the front side.

Then, as shown in FIGS. 19 and 26, in conjunction with the slide of the drive lever 52 toward the front surface, the first rotating arm 35 and the second rotating arm 36 approach each other, that is, 19 and slightly rotated in the directions of arrows a ₁ and b ₁ shown in FIG. At this time, the third rotating arm 49 is rotated integrally with the second rotating arm 36 while being in contact with the regulating piece.

  As a result, the first front-side contact member 38, the first back-side contact member 39, and the second front-side contact are placed on the outer periphery of the large-diameter disk 2A or the small-diameter disk 2B held by the turntable 23a. The contact member 40 and the roller 50 are in contact with each other.

  Next, in this disk drive device 1, the base lifting mechanism 55 lowers the base 27 to the chucking release position, thereby performing a chucking release operation for detaching the large-diameter disk 2 </ b> A from the turntable 23 a of the disk mounting portion 23. .

  Specifically, when the base 27 is lowered to the chucking release position, the tip end portion of the push-up pin 66 hits the non-signal recording area on the inner peripheral side of the large-diameter disk 2A or the small-diameter disk 2B mounted on the turntable 23a. By contacting, the large-diameter disk 2A or the small-diameter disk 2B is detached from the turntable 23a while pushing up the large-diameter disk 2A or the small-diameter disk 2B.

  Next, in this disk drive device 1, an ejection operation is performed to eject the large diameter disk 2 </ b> A or the small diameter disk 2 </ b> B in the disk mounting portion 23 from the slot 19 to the outside of the housing 3.

Specifically, when the large-diameter disk 2A is ejected from the slot 19 of the housing 3, first, as shown in FIG. 21, the third rotation is performed in conjunction with the slide of the drive lever 52 toward the front side. arm 49 is rotated in the direction of arrow _{d 2} shown in Figure 21. Further, the third rotating arm 49 is in a state in which the roller 50 is in contact with the back side of the outer peripheral portion of the large-diameter disk 2A, thereby pressing the back side of the outer peripheral portion of the large-diameter disk 2A. The large-diameter disk 2A is pushed out of the housing 3.

  When the detection unit 111 detects the large-diameter disk 2A while the large-diameter disk 2A is being ejected by the third rotating arm 49, the motor 302 is energized in the opposite direction to that during the pull-in, so The motor 302 is driven to rotate. Thereby, the third rotating arm 49 cooperates with the roller 301 to discharge the large-diameter disk 2A.

Then, as shown in FIG. 22, until the center hole 2a of the large-diameter disk 2A is located on the front side of the straight line connecting the first front-side contact member 38 and the second front-side contact member 40, When the large-diameter disk 2A is ejected to the outside of the housing 3, the first front-side contact member 38 and the second front-side contact member 40 are front-side along the outer periphery of the large-diameter disk 2A. From the back to the back. Then, in a state where the first front surface side contact member 38 and the second front surface side contact member 40 are in contact with the back surface side of the outer peripheral portion of the large-diameter disk 2A, The two rotating arms 36 are urged by the torsion coil spring 71d and the second torsion coil spring 77 and are rotated in directions close to each other, that is, in the directions of arrows a ₁ and b ₁ shown in FIG.

  When the first rotating arm 35 and the second rotating arm 36 are closed during the ejection of the large-diameter disk 2A, the contact pin 76a of the pressing lever 76 moves from the position shown in FIG. 20 in the direction of the arrow e1. Then, as shown in FIG. 22, it engages with the stepped portion of the stopper 110. As a result, the contact pin 76a cannot transmit the force that presses the stopper 110, and the torque for closing the first rotating arm 35 and the second rotating arm 36 is not provided with the stopper 110. Compared to

  Subsequently, until the detection switch (not shown) detects that the large-diameter disk 2A has reached a predetermined position, for example, the first rotation arm 35, the second rotation arm 36, the roller 301, Ejects the large-diameter disk 2A. That is, for example, when the detection switch detects that the center hole 2a of the large-diameter disk 2A is exposed to the outside of the housing 3 from the slot 19, the driving of the motor 302 is stopped. Thereby, for example, the large-diameter disk 2A is discharged from the slot 19 to a position where the center hole 2a of the large-diameter disk 2A is exposed to the outside of the housing 3, and the movement of the large-diameter disk 2A is stopped by the frictional force with the curtain or the like. .

  When the user takes out the large-diameter disk 2A from the slot 19, the force that restricts the rotation of the first rotating arm 35 and the second rotating arm 36 disappears, and the torsion coil spring 71d and the second torsion coil spring The first rotating arm 35 and the second rotating arm 36 are closed by the force of 77, moved to the HOME position, and a series of operations is completed.

On the other hand, when the small-diameter disk 2B is ejected from the slot 19 of the housing 3, first, as shown in FIG. 28, the third rotating arm 49 is interlocked with the slide toward the front side of the drive lever 52. It is rotated in the direction of arrow d ₂ shown in Figure 28. Further, the third rotating arm 49 is in a state in which the roller 50 is in contact with the back side of the outer peripheral portion of the small-diameter disk 2B, thereby pressing the back side of the outer peripheral portion of the small-diameter disk 2B. The disk 2B is pushed out of the housing 3.

  When the detection unit 111 detects the small-diameter disk 2B while the small-diameter disk 2B is being ejected by the third rotating arm 49, the motor 302 is energized in the opposite direction to that during the pull-in, so that the motor is reversed in the reverse direction. 302 is rotated. Thereby, the third rotating arm 49 cooperates with the roller 301 to discharge the small-diameter disk 2B.

24, until the center hole 2a of the small-diameter disk 2B is located on the front side of the straight line connecting the first front-side contact member 38 and the second front-side contact member 40, When the disk 2B is ejected to the outside of the housing 3, the first front-side contact member 38 and the second front-side contact member 40 are moved from the front side to the back side along the outer periphery of the small-diameter disk 2B. Wrap around. Then, in a state where the first front-side contact member 38 and the second front-side contact member 40 are in contact with the back side of the outer peripheral portion of the small-diameter disk 2B, The rotating arm 36 is biased by the torsion coil spring 71d and the second torsion coil spring 77, and is rotated in the directions close to each other, that is, in the directions of arrows a ₁ and b ₁ shown in FIG.

  The first rotating arm 35 and the second rotating arm 36 push the small-diameter disk 2B to the disk insertion / ejection position in cooperation with the roller 301 while pressing the back side of the outer peripheral portion of the small-diameter disk 2B. It will be. The disk discharge position of the small diameter disk 2B can be set to the position where the center hole 2a of the small diameter disk 2B is discharged from the slot 19 as in the case of the large diameter disk 2A. The first rotating arm 35 and the second rotating arm 36 are moved to the HOME position by the drive lever 52, and the series of operations is completed.

  When the large-diameter disk 2A or the small-diameter disk 2B is not pulled out by the user after a lapse of a certain time after the large-diameter disk 2A or the small-diameter disk 2B is discharged, the roller 301 is rotated again to rotate the inside of the slot 19 The large-diameter disk 2A or the small-diameter disk 2B may be retracted. Further, although the curtain is diverted to the guide member 304 in order to apply a friction load to the large diameter disk 2A or the small diameter disk 2B, a dedicated guide member may be provided close to the slot 19, for example.

  As described above, the disk drive device 1 according to the present embodiment includes the first transport mechanism 300 that can draw the optical disk 2 from the slot 19 side to the disk mounting portion 23 side. The optical disk 2 can be pulled into the disk mounting unit 23 without depending on the position of the optical disk 2, and the optical disk 2 pulled into the disk mounting unit 23 by the first transport mechanism 300 is first and second. Since the optical disk 2 can be released from the first transport mechanism 300 by transporting it to the mounting position by the receiving disk mounting section 23 by the rotating arms 35 and 36 and the lever member 46, for example, the first transport mechanism 300 is used. A mechanism for moving the first transport mechanism 300 in a direction perpendicular to the recording surface of the optical disk 2 to release the optical disk 2 from It can be made smaller (thinner) of the disc drive apparatus 1. In addition, the first transport mechanism 300 can automatically re-draw the optical disk 2 regardless of the position of the optical disk 2 in the slot 19, which may give the user a feeling of strangeness when inserting the optical disk 2. Absent.

  Further, a detection unit 111 for detecting whether or not the optical disc 2 is inserted into the slot 19 is further provided. For this reason, when the detection unit 111 detects that the optical disk 2 is inserted into the slot 19, the first transport mechanism 300 can pull the optical disk 2 toward the disk mounting unit 23.

  Further, the first transport mechanism 300 includes a roller 301 provided so as to rotate in contact with the recording surface of the optical disk 2 in the slot 19, a rotation driving mechanism 303 that rotates the roller 301, and the optical disk 2. And a guide member 304 that guides the roller so as to be sandwiched and drawn by the roller 301. For this reason, the optical disc 2 in the slot 19 is moved to the disc mounting portion 23 side by rotating the roller 301 by the rotation drive mechanism 303 in a state where the optical disc 2 in the slot 19 is sandwiched between the roller 301 and the guide member 304. It can be pulled in stably.

  Further, the second transport mechanism 34 receives the small diameter disk 2B from the first transport mechanism 300, cooperates with the first transport mechanism 300, and pulls the small diameter disk 2B toward the disk mounting portion 23, and In cooperation with the lever member 46, first and second rotating arms 35 and 36 are provided as conveying members for conveying the small-diameter disk 2B to the mounting position of the disk mounting portion 23. Thereby, for example, when a small-diameter disk 2B having a diameter of 8 cm is inserted into the slot 19, the lever member 46 is rotated to cooperate with the first transport mechanism 300 so that the small-diameter disk 2B is inserted into the disk mounting portion 23. Then, the first and second rotating arms 35 and 36 cooperate with the lever member 46 to smoothly transport the small-diameter disk 2B to the mounting position of the disk mounting portion 23.

(Second Embodiment)
Next, a disk drive device according to a second embodiment of the present invention will be described. In the following embodiments, the same components and the like as those in the first embodiment will be denoted by the same reference numerals, description thereof will be omitted, and different portions will be mainly described.

  FIG. 29 is a plan view showing the configuration of the disk drive device 200 according to the second embodiment.

  In the first embodiment, an example in which the disk drive device 1 includes the first transport mechanism 300 including the roller 301 that contacts the recording surface of the optical disk 2 has been described. However, in the present embodiment, the first transport mechanism 300 is provided. Instead, the disk drive device 200 includes a first transport mechanism 310 including a side roller 148 that contacts the side surface of the optical disk 2.

  The first transport mechanism 310 includes a side roller 148 provided so as to rotate in contact with the side surface of the optical disc 2 in the slot 19. Further, the first transport mechanism 310 includes a rotation driving mechanism 313 that rotationally drives the side roller 148, and guide rollers 73a and 73b that are provided so as to sandwich the optical disc 2 that is in contact with the side roller 148 between the side rollers 148. ing. The guide rollers 73a and 73b are made of a resin such as rubber. Here, for convenience of explanation, the lever member 46 that rotatably supports the side roller 148 is a member included in the second transport mechanism 34, and the guide rollers 73 a and 73 b are members included in the first transport mechanism 310. .

  The side roller 148 has a rotational axis set in a direction perpendicular to the recording surface of the optical disc 2. As the constituent material of the side roller 148, for example, a high friction material such as rubber or elastomer softer than the optical disk 2 is used.

  The guide rollers 73 a and 73 b are used to guide the optical disk 2 by inserting the side surface of the optical disk 2 with the side roller 148 when the optical disk 2 inserted into the slot 19 is pulled.

  The rotation drive mechanism 313 is configured by the side roller 148 described above, a motor 312 as a drive source for driving the side roller 148 to rotate, and a gear or the like for reducing the number of rotations of the motor 312 and transmitting it to the side roller 148. A reduction gear train 315 and a belt 316 wound around the side rollers 148 and the reduction gear train 315. In this way, the rotational driving force of the motor 312 can be transmitted to the side roller 148 via the belt 316 or the like.

  The operation of the disk drive device 200 of this embodiment will be described.

  In the disk drive device 200, for example, whether or not the optical disk 2 is inserted into the slot 19 is detected by the detection unit 111, and when the detection unit 111 detects that the optical disk 2 is inserted, it is shown in FIG. Thus, the drive lever 52 is driven to rotate the lever member 46 in the direction of the arrow c1. As a result, the side roller 148 of the lever member 46 is brought into contact with and pressed against the side surface of the optical disc 2, whereby the optical disc 2 is sandwiched between the side roller 148 and the guide rollers 73a and 73b.

  Next, the motor 312 is driven to rotate the side roller 148 in the arrow B direction via the belt 316 or the like. As a result, the optical disc 2 inserted into the slot 19 is pulled into the disc mounting portion 23 side. This is the role of the first transport mechanism 310. That is, the member having the function of drawing the optical disk 2 toward the disk mounting portion 23 (the function of the first transport mechanism 310) is the side roller 148, the belt 316 for rotating the side roller 148, the motor 312 and the guide roller 73a. Etc.

  Subsequently, the lever member 46 of the second transport mechanism 34 cooperates with the first and second rotating arms 35 and 36 to transport the optical disk 2 to the disk mounting position of the disk mounting portion 23.

  That is, the lever member 46 is rotated by driving the drive lever 52 and the optical disc 2 can be conveyed to the disc mounting position. In this way, the work performed in cooperation between the first transport mechanism 310 and the second transport mechanism 34 becomes smooth.

  In this case, after the optical disk 2 is drawn by the first transport mechanism 310 to a position where the side roller 148 can press the front side surface of the optical disk 2, the lever member 46 is rotated by driving the drive lever 52. During this period, the motor 312 may or may not actively rotate the side roller 148. When the motor 312 does not actively rotate the side roller 148, the lever member 46 and the side roller 148 are relatively rotated by the frictional resistance between the side roller 148 and the side surface of the optical disk 2.

  As described above, in the disk drive device 200 according to the present embodiment, the first transport mechanism 310 includes the side roller 148 provided so as to rotate in contact with the side surface of the optical disk 2 in the slot 19. , A rotation driving mechanism 303 for rotating the side roller 148, and a guide roller 73a for guiding the optical disc 2 so as to be sandwiched and pulled by the side roller 148. Therefore, the roller 301 is rotated by the motor 302 while the side surface of the optical disk 2 in the slot 19 is sandwiched between the side roller 148 and the guide roller 73a, so that the recording surface of the optical disk 2 is not damaged. The optical disk 2 can be pulled in.

  In this case, it is not necessary to provide another member for sandwiching the optical disc 2 pressed by the side roller 148, and the guide roller 73a can be used. Therefore, the cost and weight can be reduced without impairing the thinning. be able to.

  Further, the first transport mechanism 310 includes a lever member 46 that rotatably supports the side roller 148 so that the side roller 148 presses the side surface of the optical disc 2 in the slot 19. Therefore, by rotating the lever member 46 by driving the drive lever 52, the side roller 148 presses the side surface of the optical disc 2, and the side roller 148 rotates to cause the side roller 148 and the guide roller 73a to rotate the optical disc. The optical disk 2 in the slot 19 can be transported to the disk mounting position with the two side surfaces sandwiched. In this way, the work performed in cooperation between the first transport mechanism 310 and the second transport mechanism becomes smooth.

  Furthermore, a detection unit 111 for detecting whether or not the optical disc 2 is inserted into the slot 19 is provided. For this reason, when the detection unit 111 detects that the optical disk 2 is inserted into the slot 19, the lever member 46 is rotated to press the side roller 148 against the side surface of the optical disk 2. The optical disk 2 inserted in the slot 19 can be drawn in cooperation.

(Third embodiment)
Next, a disk drive device according to a third embodiment of the present invention will be described.

  FIG. 31 is a plan view of a disk drive device according to a third embodiment of the present invention.

  In the first and second embodiments, the disk drive devices 1 and 200 including the first rotating arm 35, the second rotating arm 36, and the interlocking mechanism 41 for interlocking these are exemplified. The disk drive device shown in FIG. 31 does not include the first rotating arm 35, the second rotating arm 36, and the interlocking mechanism 41 described above. The disk drive device shown in FIG. 31 has, for example, a first transport mechanism 310 capable of drawing a large diameter disk 2A from the slot 19 side to the disk mounting section 23 side, and a mounting position of the large diameter disk 2A by the disk mounting section 23. And a second transport mechanism for transporting to the surface.

  The first transport mechanism 310 of this embodiment includes a side roller 148 and the like, and a guide member 318 for guiding the large-diameter disk 2A so as to be sandwiched and pulled by the side roller 148.

  As shown in FIG. 31, the guide member 318 sandwiches the side surface of the large-diameter disk 2 </ b> A with the side roller 148 and guides the large-diameter disk 2 </ b> A from the slot 19 toward the disk mounting portion 23. A large diameter disk 2A is extended in the direction of drawing in the inner surface side of the side wall. As a constituent material of the guide member 318, for example, a resin material such as rubber is used in order to secure a frictional force with the optical disc 2.

  The second transport mechanism of the present embodiment includes a lever member 46 and a transport lever 317 that cooperates with the lever member 46 to transport the large-diameter disk 2 </ b> A to the mounting position by the disk mounting unit 23.

  The lever member 46 is provided to rotate so as to be pulled in until the center of the large-diameter disk 2A is aligned with the center of the disk mounting portion 23. The lever member 46 is provided so as to be rotatable in the same plane as the transport lever 317.

  The transport lever 317 is provided so as to rotate in the direction of arrow C about the support shaft 319, and a contact pin 320, for example, protrudes from a tip portion opposite to the support shaft 319 side.

  The operation of the disk drive device of this embodiment will be described.

  When the detection unit 111 detects that, for example, a large-diameter disk 2A is inserted into the slot 19, the lever member 46 is rotated by driving the drive lever 52, and the side roller 148 and the guide member 318 of the first transport mechanism 310 are rotated. And sandwich the side surface of the large-diameter disk 2A.

  Next, the side roller 148 is rotated by driving the motor 312, and the side roller 148 can press the front side surface of the large-diameter disk 2A while being sandwiched between the side roller 148 and the guide member 318. The large-diameter disk 2A is guided from the slot 19 to the disk mounting portion 23 side to the position. This is the role of the first transport mechanism 310 of the present embodiment. That is, the member having the function of drawing the optical disk 2 toward the disk mounting portion 23 (the function of the first transport mechanism 310) is the side roller 148, the belt 316 for rotating the side roller 148, the motor 312 and the guide member 318. Etc.

  Subsequently, the lever member 46 of the second transport mechanism is rotated by driving the drive lever 52, and the side roller 148 presses the front surface of the large-diameter disk 2A. As described above, the lever member 46 cooperates with the side roller 148 to convey the large-diameter disk 2A to the disk mounting portion 23 side.

  In this case, the lever member 46 is driven by the drive lever 52 after the large-diameter disk 2A is drawn by the first transport mechanism 310 to a position where the side roller 148 can press the front side surface of the large-diameter disk 2A. During the rotation, the motor 312 may or may not actively rotate the side roller 148. When the motor 312 does not actively rotate the side roller 148, the lever member 46 and the side roller 148 are relatively rotated by the frictional resistance between the side roller 148 and the side surface of the optical disk 2.

  The transport lever 317 transports the large-diameter disk 2 </ b> A to the mounting position by the disk mounting portion 23 in cooperation with the lever member 46.

  On the other hand, when the large-diameter disk 2A is ejected, the transport lever 317 functions as a lever for ejection and rotates around the support shaft 319 with the contact pin 320 in contact with the large-diameter disk 2A. The diameter disk 2A is pushed out.

  As described above, in the disk drive device according to the present embodiment, the guide member 318 extends in the direction in which the large-diameter disk 2A is drawn by the first transport mechanism 310 and is provided on the side wall of the bottom case 4. Yes. Therefore, the lever member 46 is rotated, the side roller 148 is pressed against the side surface of the large-diameter disk 2A, and the side roller 148 is rotated, so that only the lever member 46 is provided, and the side roller 148, the rotation drive mechanism 313, and the like are provided. Even when the large pressure angle is such that the guide member 318 is not retracted, the side surface of the large-diameter disk 2A is sandwiched between the side roller 148 and the guide member 318, and the guide member 318 has a large diameter in the extending direction. The disc 2A can be pulled in without damaging the recording surface.

  Further, in cooperation with the lever member 46 of the second transport mechanism, the transport lever 317 can transport the optical disk 2 from the slot 19 side to the disk mounting portion 23 side and from the disk mounting portion 23 side to the slot 19 side. it can.

  Further, as compared with the first embodiment or the like, it is not necessary to provide the first transport mechanism 300 including the roller 301, so that the disk drive device can be reduced in size.

  In the third embodiment, an example is shown in which the first transport mechanism 310 that rotates the side roller 148 and the guide member 318 are provided, but instead of the first transport mechanism 310 and the guide member 318. 3 includes the first transport mechanism 300 shown in FIG. 3 for drawing the large-diameter disk 2A inserted into the slot 19 as in the first embodiment, and the lever member 46 includes a roller similar to the side roller 48. It may be. Even in this manner, the large-diameter disk 2A inserted into the slot 19 can be pulled in regardless of the insertion position.

  In the first embodiment, an example in which the roller 301 is used is shown. However, a belt (not shown) is wound around a gear (not shown) that rotates by the rotation of the motor 302 without using the roller 301, and the optical disk 2 is conveyed by the belt. You may make it do.

  Furthermore, in the first and second embodiments, the example in which the motor 302 is provided separately from the drive motor 102 has been described. However, the mechanical force in which the drive force of the drive motor 102 is omitted without providing the motor 302 is illustrated. You may make it transmit to the roller 301 via a mechanism.
