  The holder 19 holds the CD2 when the CD2 inserted into the device main body 3 through the insertion port 10 enters inside through the opening. The plurality of holders 19 are arranged to overlap each other so that the surfaces of the CDs 2 held by the holders 19 are parallel to each other. The holder 19 is supported by the moving chassis 18 and the like so as to be movable along the thickness direction Z. The disk storage unit 6 stores a plurality of holders 19 that can hold the CD 2 in a stacked arrangement.

  The disc moving mechanism 7 is accommodated in the apparatus main body 3, moves the moving chassis 18 of both the disc reproducing unit 5 and the disc accommodating unit 6 along the thickness direction Z, and each holder 19 of the disc accommodating unit 6. Is moved in the thickness direction Z. When reading information from the CD 2 in the apparatus main body 3, the disk moving mechanism 7 moves the moving chassis 18 of the disk storage unit 6 farthest from the bottom plate 11, that is, raises it the most so that the moving chassis of the disk reproducing unit 5 has a thickness. Move along direction Z. Then, the disc moving mechanism 7 moves the holder 19 of the disc accommodating portion 6 along the thickness direction Z, moves the holder 19 holding one CD 2 away from the other holders 19, and swings between these holders 19. The other end of the moving chassis is inserted, and the information is read from the one CD 2 described above by the clamp reproducing unit of the disk reproducing unit 5.

  The disc moving mechanism 7 moves the moving chassis of the disc reproducing unit 5 closest to the bottom plate 11, that is, descends the most when the CD 2 is inserted into and removed from the inside and outside of the apparatus main body 3, and the moving chassis 18 of the disc storage unit 6 is thickened. Move along direction Z. Then, the disc moving mechanism 7 moves the holder 19 of the disc accommodating portion 6 along the thickness direction Z to hold the CD 2 inserted into the device main body 3 or to discharge the held CD 2 out of the device main body 3. The one holder 19 is moved away from the other holder 19, and the one holder 19 is positioned in a position along the depth direction Y between a later-described roller arm 21 and the disk guide 23 of the disk transport unit 4. 3 is held by the one holder 19 described above, or the CD2 held by the one holder 19 is discharged out of the apparatus main body 3.

  As shown in FIGS. 3 and 4, the disk transport unit 4 includes a main body chassis 20 as a transport unit body, a roller arm 21, a transport roller 22, a disk guide 23 as a clamping member, and a first gear 24. And a second gear 25 and a rotation support portion 26 (shown in FIG. 5).

  The main body chassis 20 is made of sheet metal, and is disposed in the vicinity of both the insertion slot 10 and the one peripheral plate 12 on the laborious side in FIG. 2, that is, in the vicinity of the motor 13 and the intermediate plate 14. The main body chassis 20 is integrally provided with a parallel portion 27 parallel to the bottom plate 11 and an upright portion 28 erected from the parallel portion 27.

  The main chassis 20 is attached to the moving chassis of the disk reproducing unit 5. For this reason, the main body chassis 20, that is, the disc transport unit 4, is movable along the thickness direction Z together with the clamp playback unit of the disc playback unit 5.

  The roller arm 21 is made of sheet metal or the like, and is formed in a strip shape whose longitudinal direction is along the width direction X of the device body 3. The roller arm 21 is disposed in the vicinity of the insertion port 10, and extends in the width direction of the main body chassis 20 around one end portion of the device main body 3 in the depth direction Y with a projecting pin 31 described later of the rotation support portion 26. It is supported rotatably around X.

  The transport roller 22 has an axis arranged in parallel with the width direction X, and is supported on the other end of the roller arm 21 so as to be rotatable around the axis. A roller driving gear 29 is coaxially fixed to the end of the transport roller 22 on the near side in FIG. The transport roller 22 is in contact with the CD 2 that passes through the insertion port 10 on the outer peripheral surface. Further, a coil spring 30 is attached to the above-described end portion of the conveyance roller 22 to urge the conveyance roller 22, that is, the other end of the roller arm 21 toward the disk guide 23. That is, the coil spring 30 serves as a biasing unit that biases the transport roller 22, that is, the roller arm 21 and the disk guide 23 toward each other.

  The disc guide 23 is made of a synthetic resin having a small coefficient of friction with the CD 2 and is formed in a strip shape. The disk guide 23 has a longitudinal direction arranged in parallel with the width direction X and is fixed to the main body chassis 20. The disk guide 23 urges the conveyance roller 22 by the coil spring 30 to sandwich the CD 2 positioned on the surface between the disk guide 23 and the conveyance roller 22.

  The first gear 24 is disposed at a distance from the roller driving gear 29 and is rotatably supported by the main body chassis 20. The first gear 24 meshes with the other gear 17 described above. For this reason, the first gear 24 is used to transmit the driving force of the motor 13 to the transport roller 22 and rotate the transport roller 22 around the axis.

  The second gear 25 is rotatably provided on the roller arm 21 and meshes with both the first gear 24 and the roller driving gear 29 described above. For this reason, the second gear 25 is rotated by the driving force of the motor 13 and rotates the gear 29 for driving the roller, that is, the conveying roller 22 around the axis. For this reason, the second gear 25 is used to transmit the driving force of the motor 13 to the transport roller 22 and rotate the transport roller 22 around the axis.

  As shown in FIG. 5, the rotation support portion 26 includes a protruding pin 31 provided on the roller arm 21 and a notch 32 serving as a through portion provided on the standing portion 28 of the main body chassis 20. . The protruding pin 31 is formed in a columnar shape and protrudes along the width direction X from one end of the roller arm 21 in the depth direction Y near the back of the device body 3.

  The notch 32 is formed by notching the standing portion 28 from the edge of the standing portion 28 near the insertion port 10 toward the back of the device main body 3. The notch 32 positions the protruding pin 31 on the inner side, and supports the roller arm 21 rotatably around the protruding pin 31. That is, the protruding pin 31 forms the rotation center of the roller arm 21. Further, the notch 32 is formed larger than the protruding pin 31 and allows the protruding pin 31 to move inside.

  The notch 32 is in contact with force vectors T1 and T2 (shown in FIGS. 6 and 7) for pressing the second gear 25 from the first gear 24 when the CD 2 is inserted into and removed from the device body 3. It extends in the direction of separation (which means approaching or leaving). Further, the notch 32 is a force vector T1, for pressing the second gear 25 from the first gear 24 at a meshing point K where the gears 24 and 25 mesh when the CD 2 is inserted and removed as will be described later. It extends in a direction crossing T2 (shown in FIGS. 6 and 7). A vector T1 (shown in FIG. 6) of the force with which the second gear 25 is pressed from the first gear 24 when the end (the lower edge 32a in the illustrated example) of the notch 32 closes the engagement position K accommodates CD2. The second gear 25 is pressed from the first gear 24 when the end (the upper edge 32b in the illustrated example) located on the front side of the notch 32 and away from the meshing location K of the notch 32 ejects CD2. The notch 32 extends in a direction intersecting the above-described vectors T1 and T2 so as to be positioned in front of the force vector T2 (shown in FIG. 7).

  With such a configuration, the notch 32 has the protruding pin 31 at the meshing point K (shown in FIGS. 6 and 7) where the first and second gears 24 and 25 mesh with each other and the force vectors T1 and T2 described above. It is allowed to move in the direction of contact and separation. In the illustrated example, the notch 32 allows the protruding pin 31 to move along the substantially thickness direction Z. Thus, the notch 32 extends in a direction closer to and away from the force vectors T1 and T2 than the protruding pin 31. The vectors T1 and T2 are along the tangential direction of the gears 24 and 25 at the meshing point K described above.

  According to the above-described configuration, when the rotation support portion 26 rotates the transport roller 22 by the driving force of the motor 13 to insert and remove the CD 2, the first gear 24 is provided in the main body chassis 20 and the second support gear 26 is provided. Since the gear 25 is provided on the roller arm 21, the projecting pin 31 is moved in the notch 32 and the roller arm 21 is projected by the reaction force when the first gear 24 rotates the second gear 25. Moments M1 and M2 (shown in FIGS. 6 and 7) that rotate about the pin 31 are generated.

  In the illustrated example, when the CD 2 is accommodated in the device main body 3, the second gear 25 is rotated in the direction of the arrow K1, as shown in FIG. Then, of course, the second gear 25 is pressed in the direction approaching the disk guide 23 along the thickness direction Z by the rotation of the first gear 24. In this way, the second gear 25 is pressed by the first gear 24 with the force of the vector T1. Then, the protruding pin 31 abuts the lower edge 32a of the notch 32, and the length L1 between the lower edge 32a of the notch 32 and the vector T1 described above is used as an arm in FIG. A rotational moment is generated in which the conveying roller 22 is moved away from the disk guide 23.

  Further, when the CD 2 is discharged out of the device main body 3, as shown in FIG. 7, the second gear 25 is rotated in the arrow K2 direction. Then, of course, the second gear 25 is pressed in the direction away from the disk guide 23 along the thickness direction Z by the rotation of the first gear 24. Thus, the second gear 25 is pressed by the force of the vector T2 by the first gear 24. Then, the protruding pin 31 abuts on the upper edge 32b of the notch 32, and the length L2 between the upper edge 32b of the notch 32 and the vector T2 described above is used as an arm in FIG. A rotation moment that causes the conveying roller 22 to approach the disk guide 23 is generated.

  Here, when the CD 2 is accommodated in the device main body 3, the distance between the upper edge 32b and the lower edge 32a of the notch 32 protrudes when the position of the protruding pin 31 is the position shown in FIG. When the movement of the protruding pin 31 is suppressed to be substantially equal to the diameter of the pin 31, the length between the lower edge 32a of the notch 32 with which the protruding pin 31 abuts and the vector T1 described above is shown in FIG. The length L1 between the lower edge 32a of the notch 32 with which the moved protruding pin 31 abuts and the vector T1 described above is shorter. Further, when the CD 2 is accommodated in the apparatus main body 3, the conveyance roller 22 is moved away from the disk guide 23, and when the CD 2 is discharged out of the apparatus main body 3, the conveyance roller 22 is brought close to the disk guide 23. The force that sandwiches the CD 2 between the transport roller 22 and the disc guide 23 when the CD 2 is accommodated in the device main body 3 is between the transport roller 22 and the disc guide 23 when the CD 2 is discharged out of the device main body 3. It is weaker than the force to sandwich CD2. However, this force difference can be reduced by the movement of the protruding pin 32.

  In this way, the rotation support portion 26 causes the transport roller 22 to move from the disc guide 23 by the driving force from the motor 13 when the CD 2 is accommodated in the device main body 3 and when the CD 2 is discharged out of the device main body 3. When the CD 2 to be moved away is accommodated in the apparatus main body 3, the projecting pin 31 that forms the rotation center of the roller arm 21 is moved so as to be movable in the direction approaching the vector T1 described above. For this reason, the rotational moment M1 when the conveying roller 22 is moved away from the disk guide 23 when the CD 2 is accommodated in the apparatus main body 3 is more than the rotational moment when the conveying roller 22 is moved away from the disk guide 23 when the protruding pin 31 does not move. Can be small. Therefore, it is possible to further reduce the difference from the force caused by the rotational moment M <b> 2 that causes the transport roller 22 to approach the disk guide 23 when the CD <b> 2 is discharged out of the apparatus body 3.

  According to the present embodiment, when the CD 2 in which the conveying roller 22 is moved away from the disk guide 23 by the motor 13 for taking in and out the CD 2 is accommodated in the apparatus main body 3, the protruding pin 31 as the rotation center of the roller arm 21 is provided. The rotational moment M1 acting on the roller arm 21 in the direction in which the conveying roller 22 moves away from the disk guide 23 is suppressed close to the vector T1 described above. For this reason, the force of moving the conveying roller 22 away from the disk guide 23 by the motor 13 when taking in / out the CD 2 is suppressed, and the decrease in the force for sandwiching the CD 2 between the conveying roller 22 and the disk guide 23 when moving away is suppressed. it can.

  Therefore, the above-described CD changer 1 can suppress the difference in the force for sandwiching the CD 2 of the disc transport unit 4 when the CD 2 is ejected and accommodated, and the CD 2 can be reliably put in and out of the apparatus main body 3.

  In addition, the rotation support portion 26 includes a protruding pin 31 and a notch 32 as a through portion that extends in a direction in which the protruding pin 31 is movably passed and contacts and separates from the vectors T1 and T2 described above. . For this reason, the protruding pin 31 as the rotation center of the roller arm 21 can be reliably moved between when the CD 2 is ejected and when it is accommodated. Can be reliably suppressed, and the CD 2 can be reliably taken in and out by the device body 3.

  In the above-described embodiment, the CD changer 1 that accommodates a plurality of CDs 2 as recording media is shown. However, the present invention may be applied to an information processing apparatus that accommodates one or more CDs, DVDs (Digital Versatile Discs), and MDs (Mini Discs) as recording media.

  In the above-described embodiment, the transport roller 22 is moved away from the disk guide 23 when the CD 2 is accommodated, and the transport roller 22 is moved closer to the disk guide 23 when the CD 2 is ejected. However, in the present invention, the transport roller 22 may be moved away from the disk guide 23 when the CD 2 is ejected, and the transport roller 22 may be moved closer to the disk guide 23 when the CD 2 is stored.

  Further, in the present invention, the projecting pin 31 may be provided in the main body chassis 20, and the roller arm 21 may be provided with a through portion such as a notch 32. In the present invention, the through portion may be formed in various shapes. Furthermore, in the present invention, not only the protruding pin 31 and the notch 32 but also the rotation support portion 26 may have various configurations.

  According to the embodiment described above, the following CD changer 1 is obtained.

An arm 21, a first gear 24 provided on the main body chassis 20 and for transmitting a driving force from the motor 13 to the conveying roller 22, and a first gear 24 provided on the roller arm 22 and the first gear 24 A disc guide that is fixed to the main body chassis 20 and sandwiches the CD 2 between the second gear 25 for transmitting the driving force from the motor 13 to the transport roller 22 and the transport roller 22. CD changer 1 with 23,
The rotation center of the roller arm 21 is movable, and the driving force from the motor 13 when the CD 2 is accommodated in the device main body 3 and when the CD 2 is discharged out of the device main body 3. When the conveying roller 22 is stored away from the disk guide 23, the rotation center of the roller arm 21 approaches the vector T1 of the force by which the second gear 25 is pressed from the first gear 24. The CD changer 1 is provided with a rotation support portion 26 that is movable to the CD changer 1.

  According to the remarks, when the CD 2 in which the conveying roller 22 is moved away from the disk guide 23 by the motor 13 when the CD 2 is taken in and out is accommodated in the device body 3, the protruding pin 31 as the rotation center of the roller arm 21 is the first. The rotational moment M1 acting on the roller arm 21 in the direction in which the conveying roller 22 moves away from the disk guide 23 is suppressed close to the force vector T1 from which the second gear 25 is pressed from the second gear 24. For this reason, the force of moving the conveying roller 22 away from the disk guide 23 by the motor 13 when taking in / out the CD 2 is suppressed, and the decrease in the force for sandwiching the CD 2 between the conveying roller 22 and the disk guide 23 when moving away is suppressed. it can. Therefore, the above-described CD changer 1 can suppress the difference in the force for sandwiching the CD 2 of the disc transport unit 4 when the CD 2 is ejected and accommodated, and the CD 2 can be reliably put in and out of the apparatus main body 3.

  In addition, the Example mentioned above only showed the typical form of this invention, and this invention is not limited to an Example. That is, various modifications can be made without departing from the scope of the present invention.
