The pickup 432 includes a light source (not shown), various lens groups including the objective lens 432A, an optical sensor (not shown), and the like.

搬送手段は、光ディスクXをケース体110内外へ搬送する。この搬送手段は、複数の図示しないアームを備えている。各アームは、細長板状に適宜形成され、それぞれ長手方向の一端部がケース体110に回動可能に軸支され、他端部が光ディスクXの周縁に当接可能となっている。そして、各アームは、制御回路部の制御により回動し、長手方向の各他端部を光ディスクXの周縁に適宜当接させ、開口部を介してケース体110内へ光ディスクXを記録面に沿って搬入あるいはケース体110外へ搬出する。   The transport means transports the optical disc X into and out of the case body 110. This transport means includes a plurality of arms (not shown). Each arm is appropriately formed in an elongated plate shape, and one end portion in the longitudinal direction is pivotally supported by the case body 110 and the other end portion can be brought into contact with the peripheral edge of the optical disc X. Each arm is rotated under the control of the control circuit unit, and the other end in the longitudinal direction is appropriately brought into contact with the peripheral edge of the optical disc X, and the optical disc X is placed on the recording surface into the case body 110 through the opening. It is carried in along or carried out of the case body 110.

駆動部450は、制御回路部からの制御によりディスク処理部200を適宜回動させる。この駆動部450は、ケース体110に配設され制御回路部に動作制御される図示しないモータと、このモータの駆動により移動する移動カム460と、を備えている。
移動カム460は、台座部210の第1,第2台座係合部216A,216Bに係合するとともにモータに係合し、モータの駆動により移動されて台座部210を回動させる。具体的には、移動カム460は、移動に伴い第1,第2台座係合部216A,216Bをケース体110の下面112に対して進退させ、台座基部211の長手方向と略直交する仮想回動軸C1を中心に台座部210を回動させる。
この台座部210の回動は、搬送手段により光ディスクXが搬送される移動経路上に、ターンテーブル310が進退する状態である。具体的には、ターンテーブル310が光ディスクXの移動経路上に進出する進出位置と、ターンテーブル310が光ディスクXの移動経路上から後退して待避する後退位置との位置間で回動させる。
The drive unit 450 appropriately rotates the disk processing unit 200 under the control of the control circuit unit. The drive unit 450 includes a motor (not shown) disposed in the case body 110 and controlled in operation by the control circuit unit, and a moving cam 460 that moves by driving the motor.
The moving cam 460 engages with the first and second pedestal engaging portions 216A and 216B of the pedestal portion 210 and engages with the motor, and is moved by driving the motor to rotate the pedestal portion 210. Specifically, the moving cam 460 moves the first and second pedestal engaging portions 216A and 216B forward and backward with respect to the lower surface 112 of the case body 110 as it moves, and is a virtual rotation substantially orthogonal to the longitudinal direction of the pedestal base portion 211. The pedestal 210 is rotated around the moving axis C1.
The rotation of the pedestal portion 210 is a state in which the turntable 310 advances and retreats on a moving path along which the optical disc X is transported by the transporting means. Specifically, the turntable 310 is rotated between a position where the turntable 310 advances on the moving path of the optical disc X and a position where the turntable 310 retracts from the moving path of the optical disc X and retracts.

制御回路部は、例えば各種電気部品が搭載された複数の回路基板470上に構成され、ディスク装置100全体の動作を制御する。
すなわち、制御回路部は、上述したように、搬送手段のアームを回動させて光ディスクXをケース体110内外へ搬送する処理、駆動部450を制御して光ディスクXの搬送状況に対応してディスク処理部200を回動させる処理、ディスク回転駆動手段230を制御して光ディスクXを適宜回転させる処理、移動処理手段350を制御してピックアップ装置430を適宜移動させる処理、ピックアップ432の制御による光ディスクXの処理、などを実施する。
The control circuit unit is configured on, for example, a plurality of circuit boards 470 on which various electrical components are mounted, and controls the operation of the entire disk device 100.
That is, as described above, the control circuit unit rotates the arm of the transport unit to transport the optical disc X into and out of the case body 110, and controls the drive unit 450 to cope with the transport status of the optical disc X.

〔ディスク装置の動作〕
次に、上述したディスク装置100の動作として、台座部210の回動動作について説明する。
図8は、台座部が進出位置まで回動した状態を示す模式図である。図9は、台座部が後退位置まで回動した状態を表す模式図である。
[Disk unit operation]
Next, as the operation of the disk device 100 described above, the rotation operation of the pedestal unit 210 will be described.
FIG. 8 is a schematic diagram illustrating a state in which the pedestal portion is rotated to the advanced position. FIG. 9 is a schematic diagram illustrating a state in which the pedestal portion is rotated to the retracted position.

ディスク装置100の台座部210は、光ディスクXがケース体110内に挿入された際に、図8に示すような進出位置に位置する。
この進出位置では、台座部210に回動可能に設けられた保持部材本体241は、回動軸方向付勢ばね部材290により、図8における時計回り方向に付勢される。そして、保持部材本体241は、時計回り方向に付勢されると、回動規制爪当接部247が回動規制爪部218に当接して時計回り方向への回動が規制され、テーブル配置面241Bおよび台座基部211の台座上端面211Aの面方向が略平行となるテーブル台座平行状態となる。そして、台座部210が進出位置に位置する際、テーブル鍔部312のテーブル載置面312Aが上面114と略平行となり、ディスク装置100は、ターンテーブル310で光ディスクXを保持する。
When the optical disc X is inserted into the case body 110, the pedestal portion 210 of the disc device 100 is located at the advanced position as shown in FIG.
In this advanced position, the holding member main body 241 rotatably provided on the pedestal 210 is urged clockwise in FIG. 8 by the rotation axis direction urging spring member 290. When the holding member main body 241 is urged clockwise, the rotation restricting claw abutting portion 247 abuts against the rotation restricting claw portion 218 and the rotation in the clockwise direction is restricted. The table pedestal is in a parallel state in which the surface direction of the surface 241B and the pedestal upper end surface 211A of the pedestal base 211 is substantially parallel. When the pedestal 210 is positioned at the advanced position, the table mounting surface 312A of the table collar 312 is substantially parallel to the upper surface 114, and the disk device 100 holds the optical disk X on the turntable 310.

また、台座部210は、例えば光ディスクXの排出時や挿入待機時に、図9に示すように、進出位置から後退位置まで回動する。
この後退位置まで回動する際に、台座部210に回動可能に設けられた保持部材本体241は、ケース体110の下面112に近接する方向へ移動して、側縁近傍部分241A1が回動補助突出部113に当接する。さらに、保持部材本体241がさらに下面112に近接する方向へ移動すると、側縁近傍部分241A1は、回動補助突出部113により下面112と対向する上面114側に押圧される。そして、側縁近傍部分241A1が上面114側に押圧されると、保持部材本体241は、回動軸方向付勢ばね部材290の付勢力に抗して、図9における反時計回り方向に回動して、テーブル配置面241Bおよび台座基部211の台座上端面211Aの面方向が交差するテーブル台座交差状態となる。
このように、保持部材本体241がテーブル台座交差状態となると、ターンテーブル310のテーブル回転軸311の回転軸上面311Aが上面114と略平行になり、回転軸上面311Aおよび上面114の間に挿入スペースS1が形成される。
ここで、保持部材本体241が台座部210に対して回動しない場合、台座部210が後退位置まで回動したとしても、テーブル台座平行状態が保たれる。そして、図9の想像線で示すように、回転軸上面311Aが上面114に対して傾斜する状態となる、つまり、保持部材本体241が回動する構成と比べて、回転軸上面311Aの図9における右側の部分が上面114側に位置する状態となるため、挿入スペースS1が狭くなる。
Further, the pedestal part 210 rotates from the advanced position to the retracted position as shown in FIG.
When rotating to the retracted position, the holding member main body 241 rotatably provided on the pedestal 210 moves in a direction approaching the lower surface 112 of the case body 110, and the side edge vicinity portion 241A1 rotates. It contacts the auxiliary protrusion 113. Further, when the holding member main body 241 further moves in a direction closer to the lower surface 112, the side edge vicinity portion 241 A 1 is pressed toward the upper surface 114 facing the lower surface 112 by the rotation assist protrusion 113. When the side edge vicinity portion 241A1 is pressed toward the upper surface 114, the holding member main body 241 rotates counterclockwise in FIG. 9 against the urging force of the rotation axis direction urging spring member 290. Then, a table pedestal crossing state occurs in which the table arrangement surface 241B and the surface direction of the pedestal upper end surface 211A of the pedestal base 211 intersect.
As described above, when the holding member main body 241 enters the table base crossing state, the rotation shaft upper surface 311A of the table rotation shaft 311 of the turntable 310 becomes substantially parallel to the upper surface 114, and an insertion space is provided between the rotation shaft upper surface 311A and the upper surface 114. S1 is formed.
Here, when the holding member main body 241 does not rotate with respect to the pedestal part 210, the table pedestal parallel state is maintained even if the pedestal part 210 is rotated to the retracted position. 9, the rotation shaft upper surface 311A is inclined with respect to the upper surface 114, that is, compared to the configuration in which the holding member main body 241 rotates, the rotation shaft upper surface 311A of FIG. Since the right-hand side portion is positioned on the upper surface 114 side, the insertion space S1 is reduced.

〔ディスク装置の作用効果〕
上述したように、上記実施の形態では、ディスク装置100に、台座基部211の長手方向と略直交する仮想回動軸C1を中心に回動可能に長手方向の一端側がケース体110に軸支された台座部210と、ターンテーブル310が設けられる保持部材本体241と、この保持部材本体241に設けられた第1,第2回動軸244,245と、台座部210に設けられ第1,第2回動軸244,245を受ける第1,第2軸受部270,280と、を設けている。
このため、台座部210を、仮想回動軸C1を中心に後退位置まで回動させた際に、第1,第2回動軸244,245を中心に保持部材本体241を台座部210に対して回動させて、台座上端面211Aおよびテーブル配置面241Bの面方向が略平行となるテーブル台座平行状態から、面方向が交差するテーブル台座交差状態に移行させることにより、面方向が略平行な回転軸上面311Aおよび上面114により構成される挿入スペースS1を形成することができる。
ここで、保持部材本体241が台座部210に対して回動しない構成の場合、台座部210が後退位置まで回動したとしても、テーブル台座平行状態が保たれるため、回転軸上面311Aが上面114に対して傾斜する状態、つまり、保持部材本体241が回動する構成と比べて回転軸上面311Aの図9における右側の部分が上面114側に位置する状態となり、上記実施の形態と比べて狭い挿入スペースS1が形成される。
したがって、台座部210および保持部材本体241をそれぞれ独立的に回動させて、回転軸上面311Aおよび上面114の面方向を略平行にすることにより、台座部210が回動しない従来の構成と比べて、広い挿入スペースS1を形成することができる。また、傾斜ガイド孔によりピンを移動させて保持部材本体241を昇降させる従来の構成と比べて、がたの影響を抑制でき、ピックアップ装置430などとの位置関係を適切に保つことができる。また、台座部210を回動させることにより保持部材本体241を昇降させるので、一般的な構造を利用することができ、従来の構成のようにトルクが大きいモータなどを設ける必要がない。さらに、保持部材本体241を2個の回動軸を中心に回動させることにより昇降させるため、上下方向に直線運動させて昇降させる構成と比べて、自由度を小さくでき、昇降の規制を容易にできる。
よって、ターンテーブル310を簡単な構成で適切な位置に移動させることができる。
さらに、保持部材本体241が台座部210に対して回動しない構成と比べて広い挿入スペースS1を形成できるので、ディスク装置100の薄型化を容易に図ることができる。
[Effects of disk unit]
As described above, in the above-described embodiment, one end side in the longitudinal direction is pivotally supported by the case body 110 so that the disk device 100 can pivot about the virtual pivot axis C <b> 1 substantially orthogonal to the longitudinal direction of the pedestal base 211. The pedestal 210, the holding member main body 241 on which the turntable 310 is provided, the first and second rotating shafts 244 and 245 provided on the holding member main body 241, and the first and first rotations provided on the pedestal 210. First and second bearing portions 270 and 280 that receive the two rotation shafts 244 and 245 are provided.
For this reason, when the pedestal part 210 is rotated about the virtual rotation axis C <b> 1 to the retracted position, the holding member main body 241 is moved relative to the pedestal part 210 about the first and second rotation axes 244 and 245. The surface direction is substantially parallel by shifting from the table pedestal parallel state in which the surface directions of the pedestal upper end surface 211A and the table disposition surface 241B are substantially parallel to each other to shift to the table pedestal crossing state in which the surface directions intersect. An insertion space S1 constituted by the rotation shaft upper surface 311A and the upper surface 114 can be formed.
Here, in the case where the holding member main body 241 is configured not to rotate with respect to the pedestal portion 210, even if the pedestal portion 210 is rotated to the retracted position, the table pedestal parallel state is maintained, so In comparison with the configuration in which the holding member main body 241 is rotated, the right side portion in FIG. 9 of the rotation shaft upper surface 311A is located on the upper surface 114 side as compared with the configuration in which the holding member main body 241 rotates. A narrow insertion space S1 is formed.
Therefore, the pedestal 210 and the holding member main body 241 are independently rotated so that the surface directions of the rotation shaft upper surface 311A and the upper surface 114 are substantially parallel to each other, so that the pedestal 210 is not rotated. Thus, a wide insertion space S1 can be formed. Further, compared to the conventional configuration in which the pin is moved by the inclined guide hole and the holding member main body 241 is moved up and down, the influence of rattling can be suppressed, and the positional relationship with the pickup device 430 and the like can be appropriately maintained. Further, since the holding member main body 241 is moved up and down by rotating the pedestal portion 210, a general structure can be used, and there is no need to provide a motor having a large torque as in the conventional configuration. Further, since the holding member main body 241 is moved up and down by rotating about two rotation shafts, the degree of freedom can be reduced and the lifting control can be easily performed as compared with a configuration in which the holding member main body 241 is moved up and down by linear movement. Can be.
Therefore, the turntable 310 can be moved to an appropriate position with a simple configuration.
Furthermore, since the insertion space S1 that is wider than the configuration in which the holding member main body 241 does not rotate with respect to the pedestal portion 210 can be formed, the disk device 100 can be easily reduced in thickness.

さらに、台座部210が進出位置まで回動した際に、保持部材本体241を回動させてテーブル台座平行状態に位置決めする構成を設けている。
このため、台座部210が進出位置まで回動した際に、保持部材本体241をテーブル台座平行状態に位置決めするので、このような位置決めする構成を設けない場合と比べて、光ディスクXをテーブル載置面312Aに適切に載置させることができる。
Furthermore, when the base part 210 rotates to the advance position, the structure which rotates the holding member main body 241 and positions to a table base parallel state is provided.
For this reason, since the holding member main body 241 is positioned in a parallel state to the table base when the base 210 is rotated to the advanced position, the optical disk X is placed on the table as compared with the case where such a positioning configuration is not provided. It can be appropriately placed on the surface 312A.

そして、保持部材本体241をテーブル台座平行状態に位置決めする構成として、保持部材本体241を回動させる状態に付勢する第1,第2ばね端突出部292,293と、保持部材本体241の回動規制爪当接部247が当接されることによりテーブル台座平行状態に位置決めする回動規制爪部218と、を適用している。
このため、第1,第2ばね端突出部292,293により保持部材本体241を一方向に回動させる状態に付勢して、回動規制爪部218で回動を規制するだけの簡単な構成で、保持部材本体241をテーブル台座平行状態に確実に位置決めできる。
Then, as a configuration in which the holding member main body 241 is positioned in the table base parallel state, the first and second spring end protrusions 292 and 293 that bias the holding member main body 241 to rotate and the holding member main body 241 rotate. A rotation restricting claw portion 218 that is positioned in a parallel state to the table base by the contact of the movement restricting claw contact portion 247 is applied.
For this reason, the holding member main body 241 is urged to be rotated in one direction by the first and second spring end projecting portions 292 and 293, and the rotation is restricted by the rotation restricting claw portion 218. With the configuration, the holding member main body 241 can be reliably positioned in the table base parallel state.

また、保持部材本体241の第1,第2回動軸244,245の軸方向への移動を規制する構成を設けている。
このため、保持部材本体241の第1,第2回動軸244,245の軸方向の移動を規制するので、ターンテーブル310の面方向へのがたつきを防止した状態で、保持部材本体241をより回動させることができる。
Moreover, the structure which controls the movement to the axial direction of the 1st, 2nd rotating shaft 244,245 of the holding member main body 241 is provided.
For this reason, since the axial movement of the first and second rotating shafts 244 and 245 of the holding member main body 241 is restricted, the holding member main body 241 is prevented in the state in which the turntable 310 is not rattled in the surface direction. Can be rotated more.

そして、保持部材本体241の第1,第2回動軸244,245の軸方向への移動を規制する構成として、保持部材本体241を第1,第2回動軸244,245の軸方向に沿って第2軸受部280の方向に付勢するコイルばね部291と、保持部材本体241の第2突出部243が当接されることにより保持部材本体241の移動を規制する軸受基部材281と、を適用している。
このため、コイルばね部291により保持部材本体241を一方向に付勢して、軸受基部材281で移動を規制するだけの簡単な構成で、保持部材本体241の第1,第2回動軸244,245の軸方向への移動を確実に規制できる。
As a configuration for restricting the movement of the first and second rotation shafts 244 and 245 in the axial direction of the holding member main body 241, the holding member main body 241 is moved in the axial direction of the first and second rotation shafts 244 and 245. A coil spring portion 291 that is urged along the direction of the second bearing portion 280 along with the bearing base member 281 that restricts the movement of the holding member main body 241 by contacting the second projecting portion 243 of the holding member main body 241. , Has been applied.
Therefore, the first and second rotating shafts of the holding member main body 241 can be configured with a simple configuration in which the holding member main body 241 is biased in one direction by the coil spring portion 291 and the movement is restricted by the bearing base member 281. The movement of 244 and 245 in the axial direction can be reliably controlled.

さらに、保持部材本体241を第1,第2回動軸244,245の軸方向に沿って付勢するコイルばね部291と、保持部材本体241を回動させる状態に付勢する第1,第2ばね端突出部292,293と、を備えた回動軸方向付勢ばね部材290を適用している。
このため、保持部材本体241を第1,第2回動軸244,245の軸方向に沿って付勢する構成と、保持部材本体241を回動させる状態に付勢する構成と、を別体で設ける構成と比べて、部品点数を減らすことができ、ディスク装置100の組立てを容易にできる。
Furthermore, the coil spring portion 291 that urges the holding member main body 241 along the axial direction of the first and second rotating shafts 244 and 245, and the first and first urging members to rotate the holding member main body 241. A rotational-axis-direction biasing spring member 290 having two spring end protrusions 292 and 293 is applied.
For this reason, the structure for urging the holding member main body 241 along the axial direction of the first and second rotating shafts 244 and 245 and the structure for urging the holding member main body 241 to rotate are separately provided. The number of parts can be reduced as compared with the configuration provided in, and the disk device 100 can be easily assembled.

また、保持部材本体241の回動中心である第1,第2回動軸244,245を、台座部210の回動中心である仮想回動軸C1と略平行に設けている。
ここで、第1,第2回動軸244,245を仮想回動軸C1と交差する状態に設けた場合、後退位置において保持部材本体241が台座部210に対して回動したとしても、図9における反時計回り方向への回動量が上記実施の形態の構成と比べて小さくなる。
したがって、第1,第2回動軸244,245を仮想回動軸C1と交差する状態に設ける構成と比べて、広い挿入スペースS1を形成することができ、ディスク装置100のさらなる薄型化を容易に図ることができる。
Further, the first and second rotation shafts 244 and 245 that are the rotation center of the holding member main body 241 are provided substantially parallel to the virtual rotation axis C <b> 1 that is the rotation center of the pedestal portion 210.
Here, when the first and second rotation shafts 244 and 245 are provided so as to intersect the virtual rotation shaft C1, even if the holding member main body 241 rotates with respect to the pedestal portion 210 in the retracted position, FIG. 9, the amount of rotation in the counterclockwise direction is smaller than that of the configuration of the above embodiment.
Therefore, compared with the configuration in which the first and second rotating shafts 244 and 245 are provided so as to intersect the virtual rotating shaft C1, a wider insertion space S1 can be formed, and the disk device 100 can be further reduced in thickness. Can be aimed at.

そして、保持部材本体241の第1回動軸244の径方向への移動を規制する構成を設けている。
このため、保持部材本体241の第1回動軸244の径方向の移動を規制するので、ターンテーブル310の面方向と交差する方向へのがたつきを防止した状態で、保持部材本体241をさらに回動させることができる。
And the structure which regulates the movement to the radial direction of the 1st rotating shaft 244 of the holding member main body 241 is provided.
For this reason, since the movement of the first rotation shaft 244 in the radial direction of the holding member main body 241 is restricted, the holding member main body 241 is held in a state in which rattling in the direction intersecting the surface direction of the turntable 310 is prevented. Further rotation is possible.

また、保持部材本体241の第1回動軸244の径方向への移動を規制する構成として、面方向が略直交する一対の第1V溝面272A1と、第1回動軸244を第1V溝面272A1の方向へ付勢する第1軸受ばね部材275と、を適用している。
このため、第1軸受ばね部材275により第1回動軸244を一方向に付勢して、第1V溝面272A1で移動を規制するだけの簡単な構成で、保持部材本体241の第1回動軸244の径方向への移動を確実に規制できる。
In addition, as a configuration for restricting the movement of the first rotation shaft 244 in the radial direction of the holding member main body 241, the pair of first V groove surfaces 272 </ b> A <b> 1 whose surface directions are substantially orthogonal to each other and the first rotation shaft 244 are connected to the first V groove. A first bearing spring member 275 that biases in the direction of the surface 272A1 is applied.
For this reason, the first rotation of the holding member main body 241 is performed with a simple configuration in which the first rotation shaft 244 is urged in one direction by the first bearing spring member 275 and the movement is restricted by the first V groove surface 272A1. The movement of the moving shaft 244 in the radial direction can be reliably restricted.

さらに、ケース体110に、台座部210が後退位置まで回動した際に、保持部材本体241に当接して回動させることにより、テーブル台座平行状態からテーブル台座交差状態に移行させる回動補助突出部113を設けている。
このため、台座部210が後退位置まで回動した際に、保持部材本体241を確実にテーブル台座交差状態に移行させることができる。したがって、十分な広さの挿入スペースS1を確実に形成でき、良好な光ディスクXの挿排を実現できる。
Further, when the pedestal part 210 is rotated to the retracted position on the case body 110, the rotation assisting protrusion is caused to shift from the table pedestal parallel state to the table pedestal crossing state by rotating by contacting the holding member main body 241. A portion 113 is provided.
For this reason, when the base 210 is rotated to the retracted position, the holding member main body 241 can be reliably shifted to the table base crossing state. Therefore, a sufficiently wide insertion space S1 can be reliably formed, and good insertion / extraction of the optical disc X can be realized.

そして、軸受基部材281に、ガイドシャフト351の位置決め機能と、第2回動軸245の位置決め機能と、を設けている。
このため、光ディスクXと、ピックアップベース431と、の位置決めを精度よくすることができる。
The bearing base member 281 is provided with a positioning function for the guide shaft 351 and a positioning function for the second rotating shaft 245.
For this reason, the positioning of the optical disk X and the pickup base 431 can be accurately performed.

〔実施の形態の変形〕
なお、本発明は、上述した一実施の形態に限定されるものではなく、本発明の目的を達成できる範囲で以下に示される変形をも含むものである。
[Modification of Embodiment]

すなわち、上記実施の形態では、ディスク装置100は、ノート型パーソナルコンピュータなどに搭載可能な薄型ディスク装置を例示したが、これに限定されず、例えばデスクトップ型パーソナルコンピュータなどに搭載される比較的大型のディスク装置にも適用することができる。   That is, in the above embodiment, the disk device 100 is exemplified as a thin disk device that can be mounted on a notebook personal computer or the like. However, the disk device 100 is not limited to this, and for example, a relatively large disk device mounted on a desktop personal computer or the like.

[Effect of the embodiment]
As described above, in the above-described embodiment, the disk device 100 includes the pedestal 210 and the turntable 310 whose one end in the longitudinal direction is pivotally supported by the case body 110 so as to be rotatable about the virtual rotation axis C1. A holding member main body 241 provided, first and second rotating shafts 244 and 245 provided on the holding member main body 241, and first and second rotating shafts 244 and 245 provided on the pedestal part 210 are received. 1 and 2nd bearing parts 270 and 280 are provided.
For this reason, when the pedestal part 210 is rotated about the virtual rotation axis C <b> 1 to the retracted position, the holding member main body 241 is moved relative to the pedestal part 210 about the first and second rotation axes 244 and 245. The surface direction is substantially parallel by shifting from the table pedestal parallel state in which the surface directions of the pedestal upper end surface 211A and the table disposition surface 241B are substantially parallel to each other to shift to the table pedestal crossing state in which the surface directions intersect. An insertion space S1 constituted by the rotation shaft upper surface 311A and the upper surface 114 can be formed.
Therefore, the pedestal 210 and the holding member main body 241 are independently rotated so that the surface directions of the rotation shaft upper surface 311A and the upper surface 114 are substantially parallel to each other, so that the pedestal 210 is not rotated. Thus, a wide insertion space S1 can be formed. Further, compared to the conventional configuration in which the pin is moved by the inclined guide hole and the holding member main body 241 is moved up and down, the influence of rattling can be suppressed, and the positional relationship with the pickup device 430 and the like can be appropriately maintained. Further, since the holding member main body 241 is moved up and down by rotating the pedestal portion 210, a general structure can be used, and there is no need to provide a motor having a large torque as in the conventional configuration. Further, since the holding member main body 241 is moved up and down by rotating about two rotation shafts, the degree of freedom can be reduced and the lifting control can be easily performed as compared with a configuration in which the holding member main body 241 is moved up and down by linear movement. Can be.
Therefore, the turntable 310 can be moved to an appropriate position with a simple configuration.
Furthermore, since the insertion space S1 that is wider than the configuration in which the holding member main body 241 does not rotate with respect to the pedestal portion 210 can be formed, the disk device 100 can be easily reduced in thickness.
