Description

本発明は、搬送機構で搬送されたディスクが回転駆動部に保持されるディスク装置に係り、特に、ディスクが搬送完了位置に移動したときに、ディスクで検知部材が押されて移動し、この検知部材の動作によって切換え部材の動作開始のタイミングが決められるディスク装置に関する。 The present invention relates to a disk device in which a disk transported by a transport mechanism is held by a rotation drive unit. In particular, when the disk moves to a transport completion position, the detection member is pushed by the disk and moved. The present invention relates to a disk device in which the operation start timing of a switching member is determined by the operation of the member.

筐体に形成されたスリット状の挿入口からディスクが挿入されるいわゆるスロットインタイプのディスク装置は、車載用などとして使用されている。このディスク装置は、筐体の内部に、ディスクの中心部を保持する回転駆動部と、搬送ローラを備えた搬送機構と、ディスクが回転駆動部に保持できる搬送完了位置まで搬送されたときにディスクの外周縁で押される検知レバーとが設けられている。 A so-called slot-in type disk device in which a disk is inserted from a slit-shaped insertion opening formed in a housing is used for in-vehicle use. The disk device includes a rotation driving unit that holds the center of the disk, a conveyance mechanism including a conveyance roller, and a disk when the disk is conveyed to a conveyance completion position that can be held by the rotation driving unit. And a detection lever that is pushed at the outer periphery of the.

挿入口から挿入されたディスクが前記搬送ローラで筐体の内部に搬送されて、ディスクの外周縁で前記検知レバーが押されて回動すると、検知レバーでラックを有する切換え部材が押されて、ラックと歯車とが噛み合う。その後は、歯車の回転によって切換え部材が移動させられ、切換え部材の移動力によってクランプ機構が動作させられる。 When the disk inserted from the insertion port is transported into the housing by the transport roller and the detection lever is pushed and rotated at the outer periphery of the disk, the switching member having a rack is pushed by the detection lever, The rack and gears mesh. Thereafter, the switching member is moved by the rotation of the gear, and the clamp mechanism is operated by the moving force of the switching member.

この方式では、検知レバーが、搬送されてくるディスクと当たることができるように、挿入口に向けて付勢されているのが一般的である。そのために、ディスクが搬送完了位置まで搬送された後に、検知レバーがディスクの外周縁に弾圧されたままとなる問題がある。 In this system, the detection lever is generally urged toward the insertion slot so that it can come into contact with the disc being conveyed. Therefore, there is a problem that the detection lever remains pressed against the outer peripheral edge of the disk after the disk is transported to the transport completion position.

そこで、以下の特許文献１に記載のディスク装置は、筐体内に検知レバーと共に板ばね部材が設けられている。ディスクが搬入されるまでは、板ばね部材によって、検知レバーがディスクに当たる向きに付勢されている。ディスクが搬送完了位置まで搬送され、ディスクの外周縁で検知レバーが押されて回動すると、検知レバーに設けられた突起が板ばね部材を乗り越え、検知レバーが、ディスクを押圧する向きに戻らないようにしている。 Therefore, in the disk device described in Patent Document 1 below, a leaf spring member is provided in the casing together with a detection lever. Until the disc is carried in, the detection lever is urged by the leaf spring member in the direction in which it hits the disc. When the disc is transported to the transport completion position and the detection lever is pushed and rotated at the outer periphery of the disc, the protrusion provided on the detection lever gets over the leaf spring member and the detection lever does not return to the direction of pressing the disc. I am doing so.

しかし、特許文献１に記載されているディスク装置は、ディスクが搬送完了位置に至った後に、検知レバーは、ディスクを弾圧する向きに回動しないように拘束されるだけであって、検知レバーがディスクの外周縁に接触できる位置に留まっている。そのため、ディスクが回転するときに、検知レバーがディスクの外周縁と摺動しやすい課題がある。 However, in the disk device described in Patent Document 1, after the disk reaches the conveyance completion position, the detection lever is only restrained so as not to rotate in the direction of repressing the disk. It remains in a position where it can contact the outer periphery of the disc. Therefore, there is a problem that the detection lever easily slides with the outer peripheral edge of the disk when the disk rotates.

他の解決方法として、前記切換え部材が移動してクランプ機構によってディスクが回転駆動部に保持された後に、さらに切換え部材の移動ストロークで検知レバーを直接押して、検知レバーを、ディスクの外周縁と当たらない位置に強制的に回動させることも考えられる。 As another solution, after the switching member is moved and the disc is held by the rotation drive portion by the clamp mechanism, the detection lever is directly pressed by the moving stroke of the switching member, and the detection lever is brought into contact with the outer peripheral edge of the disc. It is also conceivable to forcibly rotate it to a position where it does not exist.

しかし、切換え部材の移動力で検知レバーを直接に動かす構造では、検知レバーが筐体の奥側に位置しているため、この検知レバーを回動させるために切換え部材を筐体の奥側まで延長させることが必要になる。切換え部材は、前記延長分と、さらに検知レバーを回動させる分のストローク分だけ筐体の奥側に長く延ばすことが必要になるため、筐体の奥行き寸法が必要以上に長くなり、筐体の小型化を制約することになる。 However, in the structure in which the detection lever is moved directly by the moving force of the switching member, the detection lever is located on the back side of the housing, so that the switching member is moved to the back side of the housing to rotate the detection lever. It needs to be extended. Since the switching member needs to be extended to the back side of the casing for the extension and the stroke for further rotating the detection lever, the depth dimension of the casing becomes longer than necessary. This will limit the size reduction.

本発明は上記従来の課題を解決するものであり、ディスクが搬送完了位置まで移動した後に、切換え部材の移動力で検知部材をディスクから離すことができ、しかも筐体の奥側に切換え部材の移動領域を広く設けることが不要なディスク装置を提供することを目的としている。 The present invention solves the above-mentioned conventional problems, and after the disk has moved to the conveyance completion position, the detection member can be separated from the disk by the moving force of the switching member, and the switching member is disposed on the back side of the housing. An object of the present invention is to provide a disk device that does not require a wide movement area.

本発明は、回転駆動部と、ディスクの中心部を前記回転駆動部に保持させるクランプ機構と、ディスクを前記回転駆動部に保持可能な搬送完了位置に向けて搬送する搬送機構と、切換え部材と、前記切換え部材を待機位置から切換え完了位置まで移動させる動力部とを備え、前記切換え部材が待機位置から切換え完了位置へ移動する力で前記クランプ機構が動作してディスクが前記回転駆動部に保持されるディスク装置において、
搬送完了位置に至ったディスクの周縁部で押されて移動する検知部材と、前記検知部材がディスクで押されるときの移動力によって前記動力部の動力を待機位置の前記切換え部材に伝達する伝達機構とを有し、
前記検知部材と前記切換え部材との間に連結部材が設けられており、前記切換え部材が切換え完了位置へ移動するときの移動力によって前記連結部材が移動させられ、このときの前記連結部材の移動力によって、前記検知部材がディスクの外周縁から離間させられることを特徴とするものである。 The present invention relates to a rotation drive unit, a clamp mechanism that holds the center of the disk on the rotation drive unit, a conveyance mechanism that conveys the disk toward a conveyance completion position that can be held on the rotation drive unit, and a switching member. A power unit that moves the switching member from the standby position to the switching completion position, and the clamp mechanism is operated by the force of the switching member moving from the standby position to the switching completion position to hold the disk in the rotation driving unit. In the disk device to be
A detection member that is pushed and moved at the peripheral edge of the disk that has reached the conveyance completion position, and a transmission mechanism that transmits the power of the power unit to the switching member at the standby position by a moving force when the detection member is pushed by the disk. And
A connecting member is provided between the detection member and the switching member, and the connecting member is moved by a moving force when the switching member moves to the switching completion position, and the connecting member moves at this time. The detection member is separated from the outer peripheral edge of the disk by force.

本発明のディスク装置は、切換え部材が切換え完了位置まで移動するときの移動力で、検知部材がディスクから離れる位置に保持されるため、ディスクが回転するときに検知部材がディスクに当たるのを防止しやすくなる。また、検知部材は切換え部材によって直接に移動させられるのではなく、切換え部材の移動力が連結部材を介して検知部材に伝達されるため、切換え部材を装置の奥側に長く延長させる必要がなくなり、装置の奥行き寸法を短くしやすくなる。 The disk device of the present invention prevents the detection member from hitting the disk when the disk rotates because the detection member is held at a position away from the disk by the moving force when the switching member moves to the switching completion position. It becomes easy. In addition, the detection member is not moved directly by the switching member, but the moving force of the switching member is transmitted to the detection member via the connecting member, so that it is not necessary to extend the switching member to the back side of the apparatus for a long time. It becomes easy to shorten the depth dimension of the device.

本発明は、前記連結部材は、待機位置にある前記切換え部材と重なる領域で移動することが好ましい。 In the present invention, it is preferable that the connecting member moves in a region overlapping with the switching member at the standby position.

このように構成すると、切換え部材に奥方向へ延長する延長部を設けることが不要になるのみならず、切換え部材と連結部材を配置するための領域の幅寸法も短くできる。 If comprised in this way, it will become unnecessary not to provide the switching member with the extension part extended in a back direction, but the width dimension of the area | region for arrange | positioning a switching member and a connection member can also be shortened.

本発明は、前記伝達機構は、前記切換え部材に移動自在に搭載された伝達部材と、前記伝達部材に形成されたラック部とを有し、前記切換え部材が待機位置のときに前記ラック部が、前記動力部の歯車と離れており、
前記検知部材がディスクで押されるときの移動力によって前記伝達部材が移動させられると、前記ラック部と前記歯車とが噛み合って、前記切換え部材が切換え完了位置まで移動させられるものとして構成できる。 According to the present invention, the transmission mechanism includes a transmission member that is movably mounted on the switching member, and a rack portion that is formed on the transmission member. When the switching member is in a standby position, the rack portion is , Apart from the gear of the power part,
When the transmission member is moved by a moving force when the detection member is pushed by the disk, the rack portion and the gear mesh with each other, and the switching member can be moved to the switching completion position.

本発明は、前記切換え部材が待機位置のときに、前記切換え部材を前記歯車から離れる位置で拘束するロック機構が設けられており、前記ラック部と前記歯車とが噛み合って、前記伝達部材が前記切換え部材上で移動したときに、前記ロック機構によるロックが解除されることが好ましい。 The present invention is provided with a lock mechanism for restraining the switching member at a position away from the gear when the switching member is in the standby position, the rack portion and the gear mesh with each other, and the transmission member is It is preferable that the lock by the lock mechanism is released when it moves on the switching member.

上記構成では、切換え部材が待機位置のときに、切換え部材が不用意に動いて、ラック部と歯車とが噛み合ってしまう不都合を防止できるようになる。 In the above configuration, when the switching member is at the standby position, it is possible to prevent the switching member from inadvertently moving and meshing the rack portion with the gear.

例えば、本発明は、前記ロック機構は、前記切換え部材に設けられた第１のカム部と、前記伝達部材に設けられた第２のカム部と、前記連結部材に設けられて前記第１のカム部と前記第２のカム部の双方を移動するロック突起とで構成されており、
前記切換え部材が待機位置のときに、前記ロック突起が、前記第１のカム部のロック部に嵌合して、前記伝達部材が前記切換え部材上でロックされており、前記伝達部材が前記切換え部材上で移動したときに、前記ロック突起が、前記第２のカム部で案内されて第１のカム部のロック部から抜け出るものである。 For example, according to the present invention, the lock mechanism includes a first cam portion provided on the switching member, a second cam portion provided on the transmission member, and the first member provided on the connecting member. A lock protrusion that moves both the cam portion and the second cam portion;
When the switching member is in the standby position, the lock protrusion is fitted to the lock portion of the first cam portion, and the transmission member is locked on the switching member, and the transmission member is the switching member. When moved on the member, the lock protrusion is guided by the second cam portion and comes out of the lock portion of the first cam portion.

連結部材にロック突起が設けられていると、ロック機構が構成する部品数を削減できる。 If the connection member is provided with the lock protrusion, the number of parts that the lock mechanism forms can be reduced.

さらに、本発明は、前記切換え部材が切換え完了位置まで移動するときの移動力によって、前記第１のカム部で前記ロック突起が案内されて、前記連結部材が移動させられ、このときの前記連結部材の移動力によって、前記検知部材がディスクの外周縁から離間させられるものである。 Further, according to the present invention, the locking projection is guided by the first cam portion by the moving force when the switching member moves to the switching completion position, and the connecting member is moved. The detection member is separated from the outer peripheral edge of the disk by the moving force of the member.

本発明は、前記連結部材は、回動自在に支持されており、前記切換え部材が切換え完了位置まで移動するときの移動力によって前記連結部材が回動させられ、このときの前記連結部材の回動力によって、前記検知部材がディスクの外周縁から離間させられるものとして構成できる。 In the present invention, the connecting member is rotatably supported, and the connecting member is rotated by a moving force when the switching member moves to the switching completion position. The detection member can be configured to be separated from the outer peripheral edge of the disk by power.

この場合に、前記検知部材は回動動作するものであり、前記検知部材の回動軸と、前記連結部材の回動軸が、搬送完了位置まで移動したディスクと重ならない位置に配置されていることが好ましい。 In this case, the detection member rotates, and the rotation shaft of the detection member and the rotation shaft of the connecting member are arranged at positions that do not overlap with the disk that has moved to the transfer completion position. It is preferable.

検知部材の回動軸と連結部材の回動軸を、ディスクと重ならない位置に配置することで、ディスク装置の高さ寸法を小さくしやすい。 By disposing the rotation shaft of the detection member and the rotation shaft of the connecting member at a position that does not overlap the disk, the height of the disk device can be easily reduced.

なお、検知部材は、回動動作するものに限られず、切換え部材の移動方向と同じ方向または切換え部材の移動方向と交叉する方向へ、直線的に移動するものであってもよい。 The detection member is not limited to a member that rotates, and may be a member that moves linearly in the same direction as the moving direction of the switching member or in a direction that intersects the moving direction of the switching member.

本発明は、前記連結部材には、弾性変形部が一体に形成されており、
前記切換え部材が切換え完了位置まで移動するときの移動力によって前記連結部材が移動させられるときに、このときの前記連結部材の移動力が前記弾性変形部を介して前記検知部材に伝達され、前記検知部材がディスクの外周縁から離間させられる構造とすることができる。 In the present invention, the connecting member is integrally formed with an elastic deformation portion,
When the connecting member is moved by the moving force when the switching member moves to the switching completion position, the moving force of the connecting member at this time is transmitted to the detection member via the elastic deformation part, The detection member can be structured to be separated from the outer peripheral edge of the disk.

前記構成では、連結部材の移動力で検知部材を動作させるときに、連結部材と検知部材の当接部に過大な荷重が作用するのを防止できるようになる。 In the above configuration, when the detecting member is operated by the moving force of the connecting member, it is possible to prevent an excessive load from acting on the contact portion between the connecting member and the detecting member.

本発明のディスク装置は、ディスクが搬送完了位置に至ったときに、ディスクの搬送完了を検知する検知部材がディスクの外周縁から離される。よって、ディスクが回転しているときに、ディスクの外周縁と検知部材とが当たる確率を大幅に低下させることができる。 In the disk device of the present invention, when the disk reaches the transport completion position, the detection member for detecting the completion of the disk transport is separated from the outer peripheral edge of the disk. Therefore, when the disc is rotating, the probability that the outer peripheral edge of the disc hits the detection member can be greatly reduced.

また、切換え部材の移動力が連結部材を介して検知部材に与えられるため、切換え部材を装置の奥側へ長く延長させる必要がなくなり、装置の奥行き寸法を短くしやすくなる。 In addition, since the moving force of the switching member is applied to the detection member via the connecting member, it is not necessary to extend the switching member to the back side of the apparatus, and the depth dimension of the apparatus can be easily shortened.

The transmission member 30 is formed of the same synthetic resin material as that of the switching member 20. The transmission member 30 has a guide groove 31 formed on the Y2 side and a guide rib 32 formed on the Y1 side. Guide protrusions 26 and 27 projecting downward (Z2 direction) are integrally formed on the switching member 20.

The motor, the reduction gear train, and the composite gear 40 constitute a power unit.

図５に示すように、機構シャーシ１０の下面１０ｂに連結部材５０が設けられている。連結部材５０は、機構シャーシ１０と切換え部材２０との間に配置され、切換え部材２０の移動領域内に配置されている。連結部材５０は、金属板で形成されており、上方（Ｚ１方向）に延びる回動軸５１が固定されている。図５に示すように、回動軸５１が、機構シャーシ１０に形成された軸受穴１０ｆに挿通され且つ抜け止めリングなどで抜け止めされて、連結部材５０が回動自在に支持されている。 As shown in FIG. 5, a connecting member 50 is provided on the lower surface 10 b of the mechanism chassis 10. The connecting member 50 is disposed between the mechanism chassis 10 and the switching member 20, and is disposed within a moving region of the switching member 20. The connecting member 50 is formed of a metal plate, and a rotation shaft 51 extending upward (Z1 direction) is fixed. As shown in FIG. 5, the rotation shaft 51 is inserted into a bearing hole 10f formed in the mechanism chassis 10 and is prevented from being detached by a retaining ring or the like, so that the connecting member 50 is rotatably supported.

連結部材５０に、Ｙ２側の端部から下向き（Ｚ２方向）に突出する金属製のロック突起５２が固定されている。図１ないし図４に示すように、ロック突起５２は、切換え部材２０に形成された第１のカム部２４と、伝達部材３０に形成された第２のカム部３４に摺動自在に挿入されている。また、連結部材５０には比較的大きな面積の開口部５３が設けられており、この開口部５３のＹ１側の内縁が退避押圧部５４となっている。 A metal lock protrusion 52 that protrudes downward (Z2 direction) from the end on the Y2 side is fixed to the connecting member 50.

Further, the connecting member 50 is provided with an opening 53 having a relatively large area, and the inner edge of the opening 53 on the Y1 side is a retraction pressing part 54.

筐体２の奥側において、機構シャーシ１０の上面１０ａに検知部材６０が取り付けられている。検知部材６０には軸受穴６１が開口している。図５に示すように、機構シャーシ１０には上向き（Ｚ１方向）に突出する回動軸６２が固定されている。前記軸受穴６１が回動軸６２に挿通され、検知部材６０は機構シャーシ１０の上面１０ａで回動自在に支持されている。 A detection member 60 is attached to the upper surface 10 a of the mechanism chassis 10 on the back side of the housing 2. A bearing hole 61 is opened in the detection member 60. As shown in FIG. 5, a rotating shaft 62 protruding upward (Z1 direction) is fixed to the mechanism chassis 10. The bearing hole 61 is inserted into the rotation shaft 62, and the detection member 60 is rotatably supported on the upper surface 10 a of the mechanism chassis 10.

検知部材６０は、Ｘ１方向へ延びる検知腕６３を有しており、その先部に検知突起６４が上向き（Ｚ１方向）に一体に形成されている。検知突起６４は、搬送機構４によって筐体２の内部に向けて搬入されるディスクＤの外周縁と当たることができる高さ位置に配置されている。 The detection member 60 has a detection arm 63 extending in the X1 direction, and a detection projection 64 is integrally formed upward (Z1 direction) at the tip thereof. The detection protrusion 64 is disposed at a height position where the detection protrusion 64 can come into contact with the outer peripheral edge of the disk D carried into the housing 2 by the transport mechanism 4.

検知部材６０には、軸受穴６１を挟んで検知腕６３と逆側であるＸ２方向に延びる動作腕６５が形成されている。動作腕６５には、下向き（Ｚ２方向）に延びる伝達押圧突起６６と、退避制御突起６７が一体に形成されている。図５に示すように、機構シャーシ１０には逃げ穴１０ｇ，１０ｈが開口している。逃げ穴１０ｇ，１０ｈは、回動軸６２を中心とする円弧軌跡に沿って形成されている。伝達押圧突起６６は、逃げ穴１０ｇを通過して機構シャーシ１０の下側に延び、退避制御突起６７は逃げ穴１０ｈを通過して機構シャーシ１０の下側に延びている。そして、伝達押圧突起６６と退避制御突起６７が、共に連結部材５０の開口部５３の内部に入り込んでいる。 The detection member 60 is formed with an operating arm 65 extending in the X2 direction opposite to the detection arm 63 with the bearing hole 61 interposed therebetween. The operating arm 65 is integrally formed with a transmission pressing projection 66 that extends downward (Z2 direction) and a retraction control projection 67. As shown in FIG. 5, the mechanism chassis 10 has relief holes 10g and 10h. The escape holes 10g and 10h are formed along an arc locus centering on the rotation shaft 62. The transmission pressing projection 66 passes through the escape hole 10g and extends to the lower side of the mechanism chassis 10, and the retraction control projection 67 passes through the escape hole 10h and extends to the lower side of the mechanism chassis 10. The transmission pressing protrusion 66 and the retraction control protrusion 67 both enter the opening 53 of the connecting member 50.

図４に示すように、ディスクＤがターンテーブル８上に保持される搬送完了位置に至ったときに、連結部材５０の回動軸５１と検知部材６０の回動軸６２は、ディスクＤの外周縁から離れた領域に位置している。また、ディスクＤが搬送完了位置に至ったときに、連結部材５０と検知部材６０との重なり部、および連結部材５０と切換え部材２０との重なり部も、ディスクＤの外周縁から離れた位置にある。このように、回動軸５１と回動軸６２や部材どうしの重なり部を、ディスクＤの外周縁から離れた領域に配置することで、回動軸５１と回動軸６２および部材どうしの重なり部を、ディスクＤの面から離れた位置に配置することも必要でなくなり、装置全体を薄型化しやすくなる。 As shown in FIG. 4, when the disk D reaches the conveyance completion position where the disk D is held on the turntable 8, the rotation shaft 51 of the connecting member 50 and the rotation shaft 62 of the detection member 60 are outside the disk D. It is located in a region away from the periphery. Further, when the disk D reaches the conveyance completion position, the overlapping portion between the connecting member 50 and the detection member 60 and the overlapping portion between the connecting member 50 and the switching member 20 are also located at positions away from the outer peripheral edge of the disk D. is there. Thus, by arranging the overlapping part of the rotating shaft 51 and the rotating shaft 62 and the members in the region away from the outer peripheral edge of the disk D, the rotating shaft 51 and the rotating shaft 62 and the members overlap each other. It is not necessary to dispose the part at a position away from the surface of the disk D, and the entire apparatus can be easily thinned.

次に、ディスク装置１のディスク装填動作を説明する。
図１は、ディスクＤの挿入を待機するとき、または搬送中のディスクＤが未だ搬送完了位置に至っていないときの動作状態を示している。 Next, the disk loading operation of the disk device 1 will be described.
FIG. 1 shows an operation state when waiting for insertion of the disk D or when the disk D being transported has not yet reached the transport completion position.

図１では、切換え部材２０が、主ラック部２３が駆動歯車４２と噛み合うことなくＹ１方向に離れた待機位置にある。伝達部材３０は連結ばね２９によってＹ１方向に引かれて、切換え部材２０上で伝達部材３０がＹ１方向へ移動させられている。伝達部材３０が連結ばね２９でＹ１方向へ引かれるに伴い、連結部材５０に設けられたロック突起５２が、伝達部材３０に形成された第２のカム部３４のロック制御部３４ｂに導かれて差動部３４ａに移動させられる。その結果、ロック突起５２が、切換え部材２０に形成された第１のカム部２４のロック部２４ａ内に嵌合させられている。 In FIG. 1, the switching member 20 is in a standby position separated from the main rack portion 23 in the Y1 direction without meshing with the drive gear 42. The transmission member 30 is pulled in the Y1 direction by the connecting spring 29, and the transmission member 30 is moved in the Y1 direction on the switching member 20. As the transmission member 30 is pulled in the Y1 direction by the connection spring 29, the lock protrusion 52 provided on the connection member 50 is guided to the lock control portion 34b of the second cam portion 34 formed on the transmission member 30. It is moved to the differential section 34a. As a result, the lock protrusion 52 is fitted in the lock portion 24 a of the first cam portion 24 formed on the switching member 20.

図１の状態では、待機位置にある切換え部材２０とこれに搭載された伝達部材３０が、ロック突起５２を介して連結されているために、伝達部材３０が切換え部材２０上で動くことがない。また、ロック突起５２が、切換え部材２０の第１のカム部２４に形成されたロック部２４ａで保持されているため連結部材５０も回動することがない。すなわち、切換え部材２０と伝達部材３０および連結部材５０が、ロック突起５２で互いに連結されたまま、この３つの部材が筐体２内で動くことなく拘束されている。このとき、切換え部材２０の主ラック部２３と伝達部材３０の伝達ラック部３３が、共に駆動歯車４２から離れている。 In the state of FIG. 1, since the switching member 20 in the standby position and the transmission member 30 mounted on the switching member 20 are connected via the lock protrusion 52, the transmission member 30 does not move on the switching member 20. . Further, since the lock protrusion 52 is held by the lock portion 24a formed on the first cam portion 24 of the switching member 20, the connecting member 50 does not rotate. That is, the switching member 20, the transmission member 30, and the connecting member 50 are constrained without moving in the housing 2 while being connected to each other by the lock protrusion 52. At this time, the main rack portion 23 of the switching member 20 and the transmission rack portion 33 of the transmission member 30 are both separated from the drive gear 42.

なお、切換え部材２０をＹ１側に位置で安定させるために、切換え部材２０をＹ１方向へ付勢する付勢部材や、連結部材５０を図１において時計方向へ付勢する付勢部材を付加することもできる。 In order to stabilize the switching member 20 on the Y1 side, a biasing member that biases the switching member 20 in the Y1 direction and a biasing member that biases the connecting member 50 in the clockwise direction in FIG. 1 are added. You can also.

図１の状態で、検知部材６０に設けられた伝達押圧突起６６と退避制御突起６７が、連結部材５０の開口部５３の内部で動くことができ、検知部材６０が回動方向へ若干の動作余裕を有している。ただし、図１に示すように、伝達押圧突起６６が伝達部材３０の奥側（Ｙ１側）の端面の押圧受け部３９に当たるときが、検知部材６０の時計方向への回動限界である。検知部材６０が時計方向への回動限界に位置しているとき、搬送されてくるディスクＤが搬送完了位置に至る前に、検知突起６４に必ず当たる。 In the state of FIG. 1, the transmission pressing projection 66 and the retraction control projection 67 provided on the detection member 60 can move inside the opening 53 of the connecting member 50, and the detection member 60 moves slightly in the rotation direction. I have a margin. However, as shown in FIG. 1, when the transmission pressing protrusion 66 hits the pressure receiving portion 39 on the end surface (Y1 side) of the transmission member 30, the rotation limit of the detection member 60 in the clockwise direction is the limit. When the detection member 60 is positioned at the rotation limit in the clockwise direction, the transported disk D necessarily hits the detection protrusion 64 before reaching the transport completion position.

図６に示すように、切換え部材２０がＹ１方向へ移動した待機位置にあるとき、切換え部材２０のクランプ制御突起２１によって当接部１２ａが押し上げられ、クランプアーム１２が反時計方向へ回動し、クランプ部材１３がターンテーブル８から上方へ離れている。また、切換え部材２０の搬送制御突起２２が搬送ローラ５を支持するローラ支持部材から離れており、搬送ローラ５がばねの力でＺ１方向へ付勢され、搬送ローラ５と挟持部材６とでディスクＤを挟持できるようになっている。さらに、切換え部材２０がＹ１方向の待機位置にあると、切換え部材２０が筐体２の内部の拘束部と当接し、ダンパーで弾性支持されている機構シャーシ１０が自由に動くことのないように拘束されている。 As shown in FIG. 6, when the switching member 20 is in the standby position moved in the Y1 direction, the abutting portion 12a is pushed up by the clamp control projection 21 of the switching member 20, and the clamp arm 12 rotates counterclockwise. The clamp member 13 is separated upward from the turntable 8. Further, the conveyance control projection 22 of the switching member 20 is separated from the roller support member that supports the conveyance roller 5, and the conveyance roller 5 is biased in the Z <b> 1 direction by the force of the spring. D can be clamped. Further, when the switching member 20 is in the standby position in the Y1 direction, the switching member 20 abuts against the restraining portion inside the housing 2 so that the mechanism chassis 10 elastically supported by the damper does not move freely. It is restrained.

筐体２の挿入口３からディスクＤが挿入されたことが挿入検知器によって検知されると、動力部のモータが始動する。モータの動力は搬送ローラ５に伝達されて、搬送ローラ５が搬入方向（反時計方向）へ回転し始める。また、駆動歯車４２が図１において時計方向へ回転し始める。 When the insertion detector detects that the disk D has been inserted from the insertion port 3 of the housing 2, the motor of the power unit is started. The power of the motor is transmitted to the transport roller 5, and the transport roller 5 starts to rotate in the carry-in direction (counterclockwise). Further, the drive gear 42 starts to rotate clockwise in FIG.

挿入口３から挿入されたディスクＤは、搬送ローラ５と挟持部材６とで挟持され、搬送ローラ５の回転力によって筐体２の奥側（Ｙ１方向）へ向けて搬送される。ディスクＤが、ターンテーブル８とクランプ部材１３との間をＹ１方向へ向けて搬送されると、中心穴Ｄａがターンテーブル８の中心部に一致する搬送完了位置に至る前に、ディスクＤの外周縁が、図１に示す姿勢の検知部材６０に設けられた検知突起６４に当たる。そして、ディスクＤの搬送力によって、検知部材６０が強制的に時計方向へ回動させられる。 The disc D inserted from the insertion port 3 is sandwiched between the transport roller 5 and the sandwiching member 6 and transported toward the back side (Y1 direction) of the housing 2 by the rotational force of the transport roller 5. When the disk D is conveyed between the turntable 8 and the clamp member 13 in the Y1 direction, before the center hole Da reaches the conveyance completion position that coincides with the center of the turntable 8, the disk D is removed from the disk D. The peripheral edge hits the detection protrusion 64 provided on the detection member 60 in the posture shown in FIG. Then, the detection member 60 is forcibly rotated clockwise by the conveying force of the disk D.

図２に示すように、ディスクＤによって検知部材６０が時計方向へ回動させられると、検知部材６０の伝達押圧突起６６で伝達部材３０の押圧受け部３９がＹ２方向へ押される。このとき、ロック突起５２が、第１のカム部２４のロック部２４ａに嵌合しているため、切換え部材２０と連結部材５０が動くことはない。一方、ロック突起５２は、第２のカム部３４においてＹ１−Ｙ２方向に延びる差動部３４ａ内に位置しているため、伝達押圧突起６６で押された伝達部材３０のみが連結ばね２９の付勢力に対抗してＹ２方向へ移動する。そして、伝達部材３０の伝達ラック部３３が、時計方向へ回転している駆動歯車４２に噛み合う。 As shown in FIG. 2, when the detection member 60 is rotated clockwise by the disk D, the pressure receiving portion 39 of the transmission member 30 is pushed in the Y2 direction by the transmission pressing protrusion 66 of the detection member 60. At this time, since the lock protrusion 52 is fitted in the lock portion 24a of the first cam portion 24, the switching member 20 and the connecting member 50 do not move. On the other hand, since the lock projection 52 is located in the differential portion 34a extending in the Y1-Y2 direction in the second cam portion 34, only the transmission member 30 pushed by the transmission press projection 66 is attached to the connection spring 29. Move in the Y2 direction against the force. Then, the transmission rack portion 33 of the transmission member 30 meshes with the drive gear 42 rotating in the clockwise direction.

その結果、時計方向へ回転している駆動歯車４２の回転力が伝達ラック部３３に伝達されて、伝達部材３０がＹ２方向へ移動させられる。図３に示すように、この移動に伴い、ロック突起５２が、伝達部材３０の第２のカム部３４の差動部３４ａからロック制御部３４ｂに案内されてＸ２方向へ移動させられ、連結部材５０が少しだけ反時計方向へ回動する。このとき、ロック突起５２が、切換え部材２０の第１のカム部２４のロック部２４ａから抜け出て逃げ部２４ｂに移動する。 As a result, the rotational force of the drive gear 42 rotating in the clockwise direction is transmitted to the transmission rack portion 33, and the transmission member 30 is moved in the Y2 direction. As shown in FIG. 3, along with this movement, the lock protrusion 52 is guided to the lock control part 34b from the differential part 34a of the second cam part 34 of the transmission member 30 and is moved in the X2 direction. 50 rotates a little counterclockwise. At this time, the lock protrusion 52 moves out of the lock portion 24a of the first cam portion 24 of the switching member 20 and moves to the escape portion 24b.

ロック突起５２によるロックが外れるため、切換え部材２０は、伝達部材３０と共にＹ２方向へ移動し、主ラック部２３が駆動歯車４２と噛み合って、切換え部材２０がＹ２方向へ移動させられる。 Since the lock by the lock projection 52 is released, the switching member 20 moves in the Y2 direction together with the transmission member 30, the main rack portion 23 meshes with the drive gear 42, and the switching member 20 is moved in the Y2 direction.

駆動歯車４２の回転力によって切換え部材２０がＹ２方向へ駆動されると、図７に示すように、切換え部材２０に一体に設けられたクランプ制御突起２１が当接部１２ａから外れる。クランプアーム１２はクランプばね１６の付勢力によって時計方向へ回動させられ、クランプ部材１３によってディスクＤがターンテーブル８に押圧されて、ディスクＤがターンテーブル８とクランプ部材１３とで挟持されて保持される。また、切換え部材２０に形成された搬送制御突起２２のＹ２方向への移動力によって、ローラ支持部材がＺ２方向へ移動させられ、ローラ支持部材に支持されている搬送ローラ５がＺ２方向へ移動してディスクＤから離れる。ディスクＤがターンテーブル８に保持されると、ディスクＤが挟持部材６から離れ、ディスクＤにＹ１方向への搬送力が作用しなくなる。これとほぼ同時に、切換え部材２０の移動力によって、機構シャーシ１０の拘束が解除され、機構シャーシ１０がダンパーによって筐体２内で弾性支持される。 When the switching member 20 is driven in the Y2 direction by the rotational force of the drive gear 42, as shown in FIG. 7, the clamp control projection 21 provided integrally with the switching member 20 is detached from the contact portion 12a. The clamp arm 12 is rotated clockwise by the urging force of the clamp spring 16, the disk D is pressed against the turntable 8 by the clamp member 13, and the disk D is held between the turntable 8 and the clamp member 13 and held. Is done. Further, the roller support member is moved in the Z2 direction by the movement force in the Y2 direction of the conveyance control protrusion 22 formed on the switching member 20, and the conveyance roller 5 supported by the roller support member is moved in the Z2 direction. To leave the disk D. When the disk D is held on the turntable 8, the disk D is separated from the clamping member 6, and the conveying force in the Y1 direction does not act on the disk D. At substantially the same time, the movement of the switching member 20 releases the restraint of the mechanism chassis 10 and the mechanism chassis 10 is elastically supported in the housing 2 by the damper.

駆動歯車４２が主ラック部２３と噛み合って切換え部材２０がＹ２方向へ移動しているとき、切換え部材２０に設けられた第１のカム部２４の逃げ部２４ｂが、ロック突起５２と摺動し、この間は、連結部材５０が、図３よりもわずかに反時計方向へ回動した姿勢で停止している。図３に示すように、このとき、検知部材６０に設けられた伝達押圧突起６６と退避制御突起６７が、連結部材５０の開口部５３内で拘束されておらず、検知部材６０は時計方向および反時計方向へわずかな角度だけ自由に動くことができる。そのため、ディスクＤのクランプ動作を行っているときに、ディスクＤが検知部材６０の検知突起６４によってＹ２方向へ不用意に押されることがなく、中心穴Ｄａをターンテーブル８の位置決め凸部８ａに嵌合させることができる。 When the drive gear 42 meshes with the main rack portion 23 and the switching member 20 moves in the Y2 direction, the relief portion 24b of the first cam portion 24 provided on the switching member 20 slides on the lock protrusion 52. During this time, the connecting member 50 is stopped in a posture in which it is rotated slightly counterclockwise as compared with FIG. As shown in FIG. 3, at this time, the transmission pressing protrusion 66 and the retraction control protrusion 67 provided on the detection member 60 are not restrained in the opening 53 of the connecting member 50, and the detection member 60 is clockwise and It can move freely by a slight angle in the counterclockwise direction. Therefore, when the disc D is clamped, the disc D is not inadvertently pushed in the Y2 direction by the detection projection 64 of the detection member 60, and the center hole Da is formed on the positioning convex portion 8a of the turntable 8. Can be fitted.

ディスクＤがターンテーブル８に保持された後も、駆動歯車４２の回転が継続し、切換え部材２０がさらにＹ２方向へ移動して、図４に示す切換え完了位置に至る。切換え部材２０が切換え完了位置に至ったことが切換え検知部材であるリミットスイッチで検知されると、動力部のモータが停止し、駆動歯車４２が停止する。 Even after the disk D is held on the turntable 8, the rotation of the drive gear 42 continues, and the switching member 20 further moves in the Y2 direction to reach the switching completion position shown in FIG. When it is detected by the limit switch that is the switching detection member that the switching member 20 has reached the switching completion position, the motor of the power unit stops and the drive gear 42 stops.

図４に示すように、切換え部材２０が切換え完了位置に至ると、ロック突起５２が、切換え部材２０に設けられた第１のカム部２４の回動拘束部２４ｃに保持され、連結部材５０が反時計方向へ回動させられる。このとき、連結部材５０の開口部５３に設けられた退避押圧部５４によって退避制御突起６７が押され、検知部材６０が時計方向へ回動させられ、検知突起６４がディスクＤから離れる。 As shown in FIG. 4, when the switching member 20 reaches the switching completion position, the lock protrusion 52 is held by the rotation restricting portion 24 c of the first cam portion 24 provided on the switching member 20, and the connecting member 50 is It is turned counterclockwise. At this time, the retraction control projection 67 is pushed by the retraction pressing portion 54 provided in the opening 53 of the connecting member 50, the detection member 60 is rotated clockwise, and the detection projection 64 is separated from the disk D.

その後、スピンドルモータ７が回転し、ディスクＤが回転駆動され、機構シャーシ１０に設けられた光ヘッドによって、ディスクＤに対する情報の再生動作や記録動作が行われる。機構シャーシ１０は弾性支持されているため、ディスクＤは、回転しながら外部振動に応じて前後左右にやや動くが、図４に示すように、検知部材６０が時計方向へ回動させられて保持されているため、ディスクＤの外周縁が検知突起６４に当たるのを防止しやすくなる。 Thereafter, the spindle motor 7 is rotated, the disk D is rotationally driven, and an information reproducing operation and a recording operation for the disk D are performed by the optical head provided in the mechanism chassis 10. Since the mechanism chassis 10 is elastically supported, the disk D moves slightly back and forth and left and right in response to external vibration while rotating. However, as shown in FIG. 4, the detection member 60 is rotated and held clockwise. Therefore, it is easy to prevent the outer peripheral edge of the disk D from hitting the detection protrusion 64.

次に、記録動作や再生動作が完了したディスクＤを排出するときは、動力部のモータが逆転し、駆動歯車４２が反時計方向へ駆動される。駆動歯車４２により、切換え部材２０が図４の切換え完了位置からＹ１方向へ向けて移動させられる。切換え部材２０が図３の位置に復帰する間に、図６に示すように、ターンテーブル８でのディスクＤの保持が解除され、搬送ローラ５がＺ１方向へ上昇し、搬送ローラ５でディスクＤが持ち上げられて、ディスクＤが搬送ローラ５と挟持部材６で挟持される。同時に、筐体２の内部で機構シャーシ１０が拘束される。そして、搬送ローラ５の時計方向の回転力によって、ディスクＤが挿入口３から排出される。 Next, when the disk D for which the recording operation and the reproducing operation have been completed is ejected, the motor of the power unit is reversely rotated and the drive gear 42 is driven counterclockwise. The switching member 20 is moved by the drive gear 42 from the switching completion position in FIG. 4 in the Y1 direction. While the switching member 20 returns to the position of FIG. 3, as shown in FIG. 6, the holding of the disk D on the turntable 8 is released, and the transport roller 5 rises in the Z1 direction. Is lifted, and the disk D is sandwiched between the transport roller 5 and the sandwiching member 6. At the same time, the mechanism chassis 10 is restrained inside the housing 2. Then, the disk D is ejected from the insertion slot 3 by the clockwise rotational force of the transport roller 5.

切換え部材２０が図２の位置を経て図１の待機位置に戻る間に、ロック突起５２が、第２のカム部３４のロック制御部３４ｂに導かれ、ロック突起５２が、切換え部材２０に設けられた第１のカム部２４のロック部２４ａに保持されて、切換え部材２０と伝達部材３０が、駆動歯車４２から外れた待機位置でロックされる。 While the switching member 20 returns to the standby position of FIG. 1 through the position of FIG. 2, the lock projection 52 is guided to the lock control unit 34 b of the second cam portion 34, and the lock projection 52 is provided on the switching member 20. The switching member 20 and the transmission member 30 are locked at the standby position disengaged from the drive gear 42 by being held by the lock portion 24 a of the first cam portion 24.

図１に示すように、待機位置にある切換え部材２０の奥側（Ｙ１側）の端部の位置（ｉ）は、そのときの検知部材６０のＹ１側の端部の位置（ｉｉ）よりも手前側（Ｙ２側）に有る。切換え部材２０は位置（ｉ）からＹ２方向へ向けてのみ移動するため、位置（ｉｉ）よりもＹ１側に切換え部材２０の移動ストロークのためのスペースを設ける必要がない。したがって、筐体２の奥行き寸法は、図４に示す退避状態まで回動した検知部材６０の奥側の位置（ｉｉｉ）よりも奥側に若干の余裕を持たせるだけで十分であり、筐体２の前後方向の寸法を小型化しやすい。 As shown in FIG. 1, the position (i) of the rear side (Y1 side) end of the switching member 20 in the standby position is more than the position (ii) of the end of the detection member 60 on the Y1 side. Located on the near side (Y2 side). Since the switching member 20 moves only in the Y2 direction from the position (i), it is not necessary to provide a space for the moving stroke of the switching member 20 on the Y1 side from the position (ii). Therefore, the depth dimension of the housing 2 is sufficient to provide a slight margin on the back side of the back side position (iii) of the detection member 60 rotated to the retracted state shown in FIG. It is easy to reduce the size in the front-rear direction of 2.

比較例として、切換え部材２０によって直接に検知部材６０の伝達押圧突起６６をＹ２方向へ押して、検知部材６０を時計方向へ回動させる構造を想定する。この場合、図４に示すように、退避位置まで回動した検知部材６０に設けられた伝達押圧突起６６の位置（ｉｖ）よりもＹ１方向に、切換え部材２０の移動ストロークＳと、伝達押圧突起６６を押圧するために切換え部材２０に設けられる押圧部の寸法Ｔを加算した移動領域を設けることが必要になる。とすると、切換え部材２０がＹ１方向へ最も移動した待機位置において、切換え部材２０のＹ１側の端部の位置が（ｖ）となり、この位置（ｖ）が、退避位置に回動した検知部材６０の端部の位置（ｉｉｉ）よりも奥側となりやすい。前記位置（ｖ）に、さらにＹ１方向の余裕寸法を加算する必要があるため、筐体２のＹ１方向の奥行き寸法が非常に大きくなってしまう。 As a comparative example, it is assumed that the switching member 20 directly pushes the transmission pressing protrusion 66 of the detection member 60 in the Y2 direction to rotate the detection member 60 in the clockwise direction. In this case, as shown in FIG. 4, the movement stroke S of the switching member 20 and the transmission pressing protrusion in the Y1 direction from the position (iv) of the transmission pressing protrusion 66 provided on the detection member 60 rotated to the retracted position. In order to press 66, it is necessary to provide a moving region in which the dimension T of the pressing portion provided in the switching member 20 is added. Then, at the standby position where the switching member 20 is most moved in the Y1 direction, the position of the end portion on the Y1 side of the switching member 20 is (v), and this position (v) is the detection member 60 rotated to the retracted position. It is easier to be on the back side than the position (iii) of the end of the. Since it is necessary to add a margin dimension in the Y1 direction to the position (v), the depth dimension in the Y1 direction of the housing 2 becomes very large.

実施の形態のディスク装置１では、切換え部材２０の移動力が、連結部材５０を介して検知部材６０に伝達され、しかも連結部材５０が、切換え部材２０の移動ストロークの領域内で切換え部材２０と重なって配置されている。そのため、図１に示すように、待機位置のときの切換え部材２０の端部の位置（ｉ）を手前側にでき、筐体の奥側に切換え部材２０の移動ストロークのための領域を確保する必要がなくなる。特に、連結部材５０を回動式にすることで、連結部材５０の移動のための領域も狭くできる。 In the disk device 1 according to the embodiment, the moving force of the switching member 20 is transmitted to the detection member 60 via the connecting member 50, and the connecting member 50 is connected to the switching member 20 within the region of the moving stroke of the switching member 20. It is arranged overlapping. Therefore, as shown in FIG. 1, the position (i) of the end portion of the switching member 20 at the standby position can be on the near side, and an area for the moving stroke of the switching member 20 is secured on the back side of the housing. There is no need. In particular, by making the connecting member 50 pivotable, the area for movement of the connecting member 50 can be narrowed.

図４に示すように、ディスクＤが搬送完了位置に至ったときに、連結部材５０の回動軸５１と、検知部材６０の回動軸６２が、ディスクＤと重ならない位置に配置されている。さらに、連結部材５０と検知部材６０とが重なっている部分、および検知部材６０と切換え部材２０とが重なっている部分も、ディスクＤと重ならない位置に配置されている。そのため、ディスクＤが、前記回動軸や重なり部分に当たる心配がないため、筐体２の高さ寸法をさらに低くすることが可能になる。 As shown in FIG. 4, when the disk D reaches the conveyance completion position, the rotation shaft 51 of the connecting member 50 and the rotation shaft 62 of the detection member 60 are arranged at positions that do not overlap the disk D. . Further, a portion where the connecting member 50 and the detection member 60 overlap and a portion where the detection member 60 and the switching member 20 overlap are also arranged at positions where they do not overlap the disk D. Therefore, there is no fear that the disk D hits the rotating shaft or the overlapping portion, so that the height dimension of the housing 2 can be further reduced.

図８は、本発明の第２の実施の形態のディスク装置１０１の一部を示している。
このディスク装置１０１に設けられている検知部材６０は、図１ないし図７に示す実施の形態のディスク装置１検知部材６０と同じである。図８に示す連結部材６０は、前記ディスク装置１の連結部材５０と基本的な構造が同じである。ただし、図８では、連結部材５０の開口部５３の縁部に弾性変形部１５４が一体に形成されており、連結部材５０が反時計方向へ回動するときに、弾性変形部１５４によって、検知部材６０の退避制御突起６７が押圧される。 FIG. 8 shows a part of the disk device 101 according to the second embodiment of this invention.
The detection member 60 provided in the disk device 101 is the same as the disk device 1 detection member 60 of the embodiment shown in FIGS. A connecting member 60 shown in FIG. 8 has the same basic structure as the connecting member 50 of the disk device 1. However, in FIG. 8, the elastic deformation portion 154 is integrally formed at the edge of the opening 53 of the connecting member 50, and the elastic deformation portion 154 detects when the connecting member 50 rotates counterclockwise. The retraction control protrusion 67 of the member 60 is pressed.

よって、連結部材５０と退避制御突起６７との当接部に、破損に繋がるような過大な応力が作用するのを防止できる。 Therefore, it is possible to prevent an excessive stress that leads to breakage from acting on the contact portion between the connecting member 50 and the retraction control protrusion 67.
