本発明は、被駆動部材を直動させる直線駆動機構を備えた駆動装置に関するものである。 The present invention relates to a drive apparatus provided with a linear drive mechanism that linearly moves a driven member.

直線駆動機構を備えた駆動装置としては、例えば、モータの駆動力を送りねじに伝達してキャリッジを直動させ、被駆動部材を直動させる装置が提案されている（特許文献１参照）。かかる装置では、キャリッジと被駆動部材とが連結軸を介して連結されており、キャリッジと被駆動部材とは、常に一体に移動する。 As a driving device provided with a linear driving mechanism, for example, a device has been proposed which transmits the driving force of a motor to a feed screw to linearly move a carriage and linearly moves a driven member (see Patent Document 1). In such an apparatus, the carriage and the driven member are connected via the connecting shaft, and the carriage and the driven member always move integrally.

特開２００９−１２７７４２号公報JP, 2009-127742, A

特許文献１に記載の構成では、キャリッジと被駆動部材とが、常に一体に移動するため、例えば、直線駆動機構の駆動源であるモータの駆動力によって、他の機構を動作させる場合、他の機構と直線駆動機構とにおいて同一のタイミングで動作を開始することになる。このため、他の機構と直線駆動機構とにおいて異なるタイミングで動作を開始させるには、キャリッジの動作をカム機構等を介して変換して被駆動部材に伝達する必要がある等、構成が複雑化してしまう。 In the configuration described in Patent Document 1, since the carriage and the driven member always move integrally, for example, when operating the other mechanism by the driving force of the motor which is the driving source of the linear drive mechanism, The operation is started at the same timing in the mechanism and the linear drive mechanism. Therefore, in order to start operations at different timings in other mechanisms and the linear drive mechanism, the operation of the carriage needs to be converted via the cam mechanism etc. and transmitted to the driven member, etc. It will

以上の問題点に鑑みて、本発明の課題は、駆動源が動作を開始した後に被駆動部材が直動するタイミングを適正に設定することのできる駆動装置を提供することにある。 In view of the above problems, it is an object of the present invention to provide a drive device capable of appropriately setting the timing at which the driven member linearly moves after the drive source starts operation.

上記課題を解決するために、本発明に係る駆動装置は、被駆動部材と、駆動源と、前記駆動源の駆動力によって前記被駆動部材を前記第１方向の一方側および他方側に直動させる第１キャリッジを備えた直線駆動機構と、を有し、前記直線駆動機構は、前記被駆動部材と前記第１キャリッジとの機構的な接続を切り換える切り換え機構を有し、前記切り換え機構は、前記第１キャリッジが前記第１方向の一方側への移動を開始する際、前記被駆動部材と前記第１キャリッジとの機構的な接続が解除された解除状態としておき、前記第１キャリッジが前記第１方向の一方側に一定距離を移動した後、前記被駆動部材と前記第１キャリッジとが機構的に接続された接続状態とすることを特徴とする。 In order to solve the above problems, the drive device according to the present invention moves the driven member in one direction and the other side in the first direction by the driven member, the driving source, and the driving force of the driving source. And a linear drive mechanism having a first carriage, the linear drive mechanism having a switching mechanism for switching the mechanical connection between the driven member and the first carriage, the switching mechanism comprising: When the first carriage starts moving to one side in the first direction, the mechanical connection between the driven member and the first carriage is released, and the first carriage is placed in the released state. After moving a fixed distance to one side in the first direction, the driven member and the first carriage are brought into a connected state in which they are mechanically connected.

本発明では、第１キャリッジが移動を開始した場合でも、切り換え機構では、被駆動部材と第１キャリッジとの機構的な接続が解除された解除状態になっているので、被駆動部材が第１方向の一方側に移動しない。また、第１キャリッジが第１方向の一方側に一定距離を移動して、切り換え機構において、被駆動部材と第１キャリッジとが機構的に接続された接続状態になれば、被駆動部材は、第１キャリッジとともに第１方向の一方側に移動する。従って、駆動源が動作を開始した後、被駆動部材が直動するタイミングを適正に設定することができる。 In the present invention, even when the first carriage starts moving, in the switching mechanism, since the mechanical connection between the driven member and the first carriage is released, the driven member is in the first state. Do not move to one side of the direction. In addition, when the first carriage moves a certain distance to one side in the first direction and the driven member and the first carriage are mechanically connected in the switching mechanism, the driven member is: It moves to one side in the first direction together with the first carriage. Therefore, after the drive source starts operation, the timing at which the driven member linearly moves can be properly set.

本発明において、前記切り換え機構は、前記第１方向に交差する軸線周りに回転可能に前記第１キャリッジに支持されたレバーと、前記第１キャリッジの前記第１方向の移動に伴って前記レバーを回転させて、前記接続状態では前記被駆動部材と前記レバーとを係合
させ、前記解除状態では、前記被駆動部材と前記レバーとの係合を解除するカム機構と、を有している構成を採用することができる。 In the present invention, the switching mechanism comprises: a lever rotatably supported by the first carriage about an axis intersecting the first direction; and the lever along with the movement of the first carriage in the first direction. It has a cam mechanism which is rotated to engage the driven member and the lever in the connected state, and release the engagement between the driven member and the lever in the released state.

本発明において、前記被駆動部材は前記係合軸を有し、前記レバーには、前記解除状態から前記接続状態に切り換わる際に前記係合軸が開放端側から内側に嵌る凹部が設けられ、前記凹部の前記第１方向の他方側の縁によって前記第１当接部が構成され、前記凹部の前記第１方向の一方側の縁によって前記第２当接部が構成されている態様を採用することができる。 In the present invention, the driven member has the engagement shaft, and the lever is provided with a recess in which the engagement shaft is fitted inward from the open end side when switching from the release state to the connection state. A mode in which the first contact portion is constituted by the edge on the other side in the first direction of the recess and the second contact portion is constituted by the edge on the one side in the first direction of the recess It can be adopted.

この場合、前記第１キャリッジは、前記凹部内からの前記係合軸の抜けを防止する抜け止め用の凸部を備えていることが好ましい。 In this case, it is preferable that the first carriage is provided with a protrusion for preventing the engagement shaft from coming out of the recess.

本発明において、前記直線駆動機構は、前記駆動源の駆動力によって前記第１方向に延在する軸線周りに回転して前記第１キャリッジを前記第１方向に移動させる送りねじを備えている態様を採用することができる。 In the present invention, the linear drive mechanism includes a feed screw that rotates around an axis extending in the first direction by a driving force of the drive source to move the first carriage in the first direction. Can be adopted.

本発明において、前記送りねじは、第１ピッチで螺旋溝が設けられた第１ねじ部と、前記第１ピッチより短い第２ピッチで螺旋溝が設けられた第２ねじ部と、を有していることが好ましい。かかる構成によれば、第１キャリッジが第１ねじ部と係合している期間では、第１キャリッジが第２ねじ部と係合している期間より高速で移動させることができる。また、第１キャリッジが第２ねじ部と係合している期間では、送りねじの回転を停止させた状態で第１キャリッジと第２ねじ部とがセルフロック状態となる。従って、第１キャリッジが不用意に移動することを抑制することができる。 In the present invention, the feed screw has a first screw portion provided with a spiral groove at a first pitch, and a second screw portion provided with a spiral groove at a second pitch shorter than the first pitch. Is preferred. According to this configuration, while the first carriage is engaged with the first screw portion, it can be moved at a higher speed than the period during which the first carriage is engaged with the second screw portion. In addition, during a period in which the first carriage is engaged with the second screw portion, the first carriage and the second screw portion are in a self-locking state while the rotation of the feed screw is stopped. Therefore, it is possible to suppress the careless movement of the first carriage.

本発明において、前記送りねじは、前記第１ねじ部に対して前記第１方向の両側に前記第２ねじ部を有していることが好ましい。かかる構成によれば、被駆動部材の移動動作の初期および終期において被駆動部材を低速度で移動させるとともに、中間区間では、被駆動部材を高速度で移動させることができる。 In the present invention, preferably, the feed screw has the second screw portion on both sides in the first direction with respect to the first screw portion. According to this configuration, the driven member can be moved at low speed at the initial and final stages of the moving operation of the driven member, and the driven member can be moved at high speed in the intermediate section.

本発明において、前記第１方向の一方側に向けて開口する開口部を備えたフレームと、前記開口部を塞ぐ開閉部材と、前記駆動源の駆動力によって前記開閉部材を駆動して前記開口部を開閉する開閉機構と、を有し、前記直線駆動機構は、前記被駆動部材を前記第１方向の一方側および他方側に直動させて前記被駆動部材を前記開口部から外側に突出した出現位置と前記開口部から内側に引っ込んだ待機位置との間で移動させる態様を採用することができる。かかる構成によれば、開閉部材による開口部の開閉と、被駆動部材の待機位置と待機位置との間の駆動とを行う場合でも、開閉機構および直線駆動機構では、駆動源が共通になっている。従って、駆動装置の構成の簡素化を図ることができる。この場合、被駆動部材と開閉部材とが干渉することを回避することができるが、本発明では、駆動源が動作を開始した後、被駆動部材が直動するタイミングを適正に設定することができるため、被駆動部材と開閉部材との干渉を回避することができる。 In the present invention, a frame having an opening that opens toward one side in the first direction, an opening and closing member that closes the opening, and the opening and closing member driven by the driving force of the drive source. And the linear drive mechanism projects the driven member outward from the opening by causing the driven member to move linearly to one side and the other side in the first direction. It is possible to adopt an aspect of moving between the appearance position and the standby position which is recessed inward from the opening. According to this configuration, even when the opening and closing of the opening by the opening and closing member and the drive between the standby position and the standby position of the driven member are performed, the drive source is common to the opening and closing mechanism and the linear drive mechanism. There is. Therefore, the configuration of the drive device can be simplified. In this case, interference between the driven member and the opening / closing member can be avoided, but in the present invention, it is possible to properly set the timing at which the driven member linearly moves after the driving source starts operation. Therefore, interference between the driven member and the opening / closing member can be avoided.

本発明において、前記開閉機構は、前記駆動源の駆動力によって前記開口部を閉状態とする位置から前記第１方向と交差する第２方向に沿って前記開閉部材をスライドさせて前記開閉部材に対する前記第２方向の一方側で前記開口部を開状態とすることが好ましい。かかる構成によれば、被駆動部材が出現する側に開閉部材が突出しない。従って、開閉部材の存在が邪魔になりにくい。 In the present invention, the opening and closing mechanism slides the opening and closing member along a second direction crossing the first direction from a position where the opening is closed by the driving force of the drive source, thereby causing the opening and closing member to move. It is preferable to open the opening on one side in the second direction. According to this configuration, the opening and closing member does not protrude to the side where the driven member appears. Therefore, the presence of the opening and closing member is less likely to interfere.

本発明において、前記開閉部材は、第１部材と第２部材とを備え、前記開閉機構は、前記閉状態では前記第１部材が前記第２部材に対して前記第２方向の他方側に並んだ状態とし、前記開状態では前記第２部材を前記第２方向の他方側に移動させて前記第１方向で前記第１部材と重なった状態で前記第１部材および前記第２部材の前記第２方向の一方側の端部または前記第２方向の他方側の端部が前記フレーム内に引き込まれた斜め姿勢とすることが好ましい。かかる構成によれば、開閉部材の存在が邪魔になりにくい。 In the present invention, the opening and closing member includes a first member and a second member, and in the opening and closing mechanism, the first member is arranged on the other side in the second direction with respect to the second member in the closed state. In the open state, the second member is moved to the other side in the second direction, and the second member is overlapped with the first member in the first direction. It is preferable that an end on one side in two directions or an end on the other side in the second direction be in a diagonal posture drawn into the frame. According to this configuration, the presence of the opening and closing member is less likely to be an obstacle.

本発明において、前記駆動源の駆動力によって前記被駆動部材の先端側を前記第１方向と交差する第２方向の一方側または他方側に傾かせるチルト駆動機構を有し、前記直線駆動機構は、前記被駆動部材が前記待機位置から前記出現位置に向けて移動するまで前記被駆動部材の姿勢を規制するガイド部材を有し、前記チルト駆動機構は、前記ガイド部材による前記被駆動部材の姿勢の規制が解除された後、前記直線駆動機構が前記被駆動部材をさらに前記出現位置に向けて駆動した際に前記第２方向の一方側または他方側で前記被駆動部材が当接する当接部を有することが好ましい。かかる構成によれば、１つの駆動源を用いるという簡素な構成で、開口部を介しての被駆動部材の出し入れ、および被駆動部材の姿勢の調整を行うことができる。また、被駆動部材が当接部に当接した際に被駆動部材の先端側が第２方向に傾くため、被駆動部材の直動を利用して被駆動部材の姿勢を切り換えることができる。また、被駆動部材を傾かせる際、直動する距離が長ければ、被駆動部材を大きく傾けることができる等、被駆動部材の姿勢を調整することができる。かかる構成によれば、比較的簡素な構成で被駆動部材の姿勢を切り換えることができる。 In the present invention, the linear drive mechanism includes a tilt drive mechanism which tilts the tip end side of the driven member to one side or the other side in a second direction crossing the first direction by the driving force of the drive source. And a guide member that regulates the posture of the driven member until the driven member moves from the standby position toward the appearance position, and the tilt drive mechanism is configured to adjust the posture of the driven member by the guide member. The contact part with which the driven member abuts on one side or the other side of the second direction when the linear drive mechanism further drives the driven member toward the appearance position after the restriction of the restriction is released. It is preferable to have According to this configuration, it is possible to perform the insertion and removal of the driven member through the opening and the adjustment of the posture of the driven member with a simple configuration in which one drive source is used. Further, since the tip end side of the driven member is inclined in the second direction when the driven member abuts on the contact portion, the posture of the driven member can be switched by utilizing the linear motion of the driven member. Further, when tilting the driven member, if the linear movement distance is long, the attitude of the driven member can be adjusted, for example, the driven member can be largely tilted. According to this configuration, the posture of the driven member can be switched with a relatively simple configuration.

本発明において、前記直線駆動機構は、前記フレームに固定されたガイド軸と、前記ガイド軸が貫通するガイド穴が設けられ、前記被駆動部材を前記第２方向に揺動可能に支持した状態で前記被駆動部材と一体に直線移動する第２キャリッジと、前記第２キャリッジと前記被駆動部材との間に設けられ、前記被駆動部材を前記当接部に当接する方向に付勢する第２付勢部材と、を有することが好ましい。かかる構成によれば、簡素な構成でチルト駆動機構を適正に動作させることができる。 In the present invention, the linear drive mechanism is provided with a guide shaft fixed to the frame and a guide hole through which the guide shaft passes, and in a state where the driven member is supported so as to be able to swing in the second direction. A second carriage linearly moving integrally with the driven member, and a second carriage provided between the second carriage and the driven member to urge the driven member in a direction to abut the contact portion. It is preferable to have a biasing member. According to this configuration, the tilt drive mechanism can be properly operated with a simple configuration.

本発明において、前記駆動源は、双方向の回転を出力可能なモータである構成を採用することができる。この場合、前記モータは、互いに反対側に向けて突出した第１出力軸および第２出力軸を備え、前記第１出力軸から出力される駆動力によって前記開閉機構が動作し、前記第２出力軸から出力される駆動力によって前記直線駆動機構が動作する態様を採用することができる。 In the present invention, the drive source can adopt a configuration that is a motor capable of outputting bi-directional rotation. In this case, the motor includes a first output shaft and a second output shaft projecting toward the opposite side, and the opening / closing mechanism is operated by the driving force output from the first output shaft, and the second output is generated.

本発明では、第１キャリッジが移動を開始した場合でも、切り換え機構では、被駆動部材と第１キャリッジとの機構的な接続が解除された解除状態になっているので、被駆動部材が第１方向の一方側に移動しない。また、第１キャリッジが第１方向の一方側に一定距離を移動して、切り換え機構において、被駆動部材と第１キャリッジとが機構的に接続された接続状態になれば、被駆動部材は、第１キャリッジとともに第１方向の一方側に移動する。従って、駆動源が動作を開始した後、被駆動部材が直動するタイミングを適正に設

In addition, when the first carriage moves a certain distance to one side in the first direction and the driven member and the first carriage are mechanically connected in the switching mechanism, the driven member is: It moves to one side in the first direction together with the first carriage. Therefore, after the drive source starts operation, the timing at which the driven member linearly moves can be properly set.

（開閉動作）
図７は、本発明を適用した複合駆動装置１の開閉機構６の動作を示す説明図である。なお、図７では、閉状態における開閉部材４等の位置を実線で示し、開状態における開閉部材４等の位置を一点鎖線で示してある。 (Opening and closing operation)
FIG. 7 is an explanatory view showing the operation of the opening / closing mechanism 6 of the combined drive system 1 to which the present invention is applied. In FIG. 7, the positions of the opening and closing member 4 and the like in the closed state are indicated by solid lines, and the positions of the opening and closing member 4 and the like in the open state are indicated by dashed dotted line.

図７に示すように、開閉部材４によってフレーム２の開口部２０を塞いだ閉状態では、アーム状の回転部材６６は、第１方向Ｙの一方側Ｙ１に向かって起立した状態にあり、この状態で、開閉部材４では、第１部材４１が第２部材４２に対して第２方向Ｚの他方側Ｚ２に並んだ状態にある。かかる閉状態において、ピニオン６２は、第１スリット６１３の第２部分６１３ｂに位置する。また、ピニオン６２は、第２方向Ｚにおいて第１部材４１と第２部材４２との間にある。このため、第１ラック４１０のうち、段部４１２において、第２方向Ｚの一方側Ｚ１に向く端部に形成された部分が第２方向Ｚの他方側Ｚ２からピニオン６２と噛み合い、第２ラック４２０のうち、段部４２２において、第２方向Ｚの他方側Ｚ２に向く端部に形成された部分が第２方向Ｚの一方側Ｚ１からピニオン６２と噛み合っている。 As shown in FIG. 7, in the closed state in which the opening 20 of the frame 2 is closed by the opening / closing member 4, the arm-shaped rotating member 66 is in a state of standing up toward one side Y1 in the first direction Y. In the state, in the opening / closing member 4, the first member 41 is aligned with the second member 42 on the other side Z2 in the second direction Z. In the closed state, the pinion 62 is located at the second portion 613 b of the first slit 613. Also, the pinion 62 is between the first member 41 and the second member 42 in the second direction Z. For this reason, in the step portion 412 of the first rack 410, the portion formed at the end facing the one side Z1 in the second direction Z meshes with the pinion 62 from the other side Z2 in the second direction Z, and the second rack Of the step 420, in the step 422, a portion formed at the end facing the other side Z2 in the second direction Z meshes with the pinion 62 from the one side Z1 in the second direction Z.

この状態からモータ５０が一方方向に回転すると、モータ５０の回転駆動力が、図４等に示す伝達機構６７（歯車伝達機構６８およびベルト伝達機構６９）を介して回転部材６６に伝達される。従って、回転部材６６が第３軸線Ｌ３周りに矢印Ｃで示す一方方向に回転し、回転部材６６と第１部材４１との接続部６０が第３軸線Ｌ３周りに、矢印Ｃで示す一方方向に回転する。このため、接続部６０の軸４４２は、第２スリット６１４に沿って、第１軸線Ｌ１に接近する方向に移動する。従って、第１部材４１は、ホルダ６１に支持されたまま、矢印Ａ１で示すように、第１軸線Ｌ１に接近する方向に移動する。その結果、ホルダ６１は、第１軸線Ｌ１周りに矢印Ｂで示す方向に回転する。その際、ピニオン６２は、第２軸線Ｌ２周りに回転しながら第１ラック４１０に乗り上げ、ピニオン６２と第１ラック４１０との噛み合い位置が第１ラック４１０の第２方向Ｚの他方側Ｚ２に移動する。また、ピニオン６２の回転によって、第２ラック４２０は、第１ラック４１０とは反対側でピニオン６２に乗り上げ、ピニオン６２と第２ラック４２０との噛み合い位置が第２ラック４２０の第２方向Ｚの一方側Ｚ１に移動する。従って、第２部材４２は、矢印Ａ２で示すように、第２方向Ｚの他方側Ｚ２に移動し、ピニオン６２を挟んで第１部材４１に対して第１方向Ｙの一方側Ｙ１に重なる。かかる状態において、第１部材４１および第２部材４２は、第２方向Ｚの他方側Ｚ２の端部４１ａ、４２ａがフレーム２内に引き込まれた斜め姿勢となる。また、第２部材４２の少なくとも第２方向Ｚの一方側Ｚ１（開閉部材４の第２方向Ｚの一方側Ｚ１）では、開口部２０が開口した開状態となる。本形態では、開閉部材４の第２方向Ｚの他方側Ｚ１でも、フレーム２の開口部が開口した状態となるが、かかる開口部は、被駆動部材３の出し入れには用いられない。 When the motor 50 rotates in one direction from this state, the rotational driving force of the motor 50 is transmitted to the rotating member 66 via the transmission mechanism 67 (the gear transmission mechanism 68 and the belt transmission mechanism 69) shown in FIG. Therefore, the rotating member 66 rotates around the third axis L3 in one direction indicated by the arrow C, and the connecting portion 60 between the rotating member 66 and the first member 41 around the third axis L3 in the one direction indicated by the arrow C Rotate. For this reason, the axis 442 of the connection portion 60 moves along the second slit 614 in a direction approaching the first axis L1. Therefore, while being supported by the holder 61, the first member 41 moves in the direction approaching the first axis L1, as indicated by the arrow A1. As a result, the holder 61 rotates in the direction indicated by the arrow B around the first axis L1. At that time, the pinion 62 rides on the first rack 410 while rotating around the second axis L2, and the meshing position of the pinion 62 and the first rack 410 moves to the other side Z2 of the first rack 410 in the second direction Z. Do. Further, by rotation of the pinion 62, the second rack 420 rides on the pinion 62 on the opposite side to the first rack 410, and the meshing position between the pinion 62 and the second rack 420 is in the second direction Z of the second rack 420. Move to one side Z1. Therefore, the second member 42 moves to the other side Z2 in the second direction Z, as shown by the arrow A2, and overlaps the first member 41 on the one side Y1 in the first direction Y with the pinion 62 interposed therebetween. In this state, the first member 41 and the second member 42 are in an oblique posture in which the end portions 41a and 42a of the other side Z2 in the second direction Z are drawn into the frame 2. In addition, at least one side Z1 in the second direction Z of the second member 42 (one side Z1 in the second direction Z of the opening / closing member 4), the opening 20 is in an open state. In the present embodiment, the opening of the frame 2 is open also on the other side Z1 of the opening / closing member 4 in the second direction Z, but such an opening is not used for loading and unloading of the driven member 3.

かかる開状態からモータ５０が他方方向に回転し、モータ５０の回転駆動力が、開閉機構６の伝達機構６７（歯車伝達機構６８およびベルト伝達機構６９）を介して回転部材６６に伝達されると、回転部材６６が第３軸線Ｌ３周りに矢印Ｃで示す一方方向とは反対側の他方方向に回転し、回転部材６６と第１部材４１との接続部６０が第３軸線Ｌ３周りに
、矢印Ｃで示す一方方向とは反対側の他方方向に回転する。このため、接続部６０は、第２スリット６１４に沿って、第１軸線Ｌ１から離間する方向に移動する。従って、上記の動作とは反対側の動作が行われる結果、第２部材４２が第２方向Ｚの一方側Ｚ１に移動するので、第２部材４２の第２方向Ｚの一方側Ｚ１（開閉部材４の第２方向Ｚの一方側Ｚ１）で開口部２０が開閉部材４で塞がれた閉状態となる。 When the motor 50 rotates in the other direction from the open state, and the rotational driving force of the motor 50 is transmitted to the rotating member 66 via the transmission mechanism 67 (the gear transmission mechanism 68 and the belt transmission mechanism 69) of the opening / closing mechanism 6. The rotating member 66 rotates around the third axis L3 in the other direction opposite to the one shown by the arrow C, and the connecting portion 60 between the rotating member 66 and the first member 41 is an arrow around the third axis L3. It rotates in the other direction opposite to one direction indicated by C. For this reason, the connection portion 60 moves along the second slit 614 in a direction away from the first axis L1. Therefore, as a result of the movement on the opposite side to the above movement being performed, the second member 42 moves to the one side Z1 in the second direction Z, so that the one side Z1 in the second direction Z of the second member 42 (opening member The opening 20 is closed by the opening / closing member 4 on one side Z1) of the second direction Z in 4).

And a base 32 for holding the end of the other side Y2. The main body 31 is in the form of a panel whose thickness direction is oriented in the second direction Z. The base 32 has a dimension in the third direction X larger than that of the main body portion 31 and a dimension in the second direction Z larger than that of the main body portion 31.

（直線駆動機構７の構成）
直線駆動機構７は、第１方向Ｙに延在する軸線Ｌ４周りに回転する送りねじ７０と、送りねじ７０と係合する第１キャリッジ７１とを有しており、第１キャリッジ７１は、被駆動部材３を待機位置から出現位置に移動させる際に第１方向Ｙの一方側Ｙ１に移動する。本形態において、送りねじ７０の両端部は、フレーム２に支持された支持部材７８によって回転可能に支持されている。直線駆動機構７は、モータ５０の第２出力軸５２に固定された第１歯車７５１、第１歯車７５１と噛み合う第２歯車７５２、および第２歯車７５２と噛み合う第３歯車７５３からなる歯車伝達機構７５を有しており、第３歯車７５３は、送りねじ７０の端部７０９に固定されている。従って、送りねじ７０は、モータ５０の駆動力によって軸線Ｌ４周りに回転する。 (Configuration of linear drive mechanism 7)
The linear drive mechanism 7 has a feed screw 70 that rotates around an axis L4 extending in the first direction Y, and a first carriage 71 that engages with the feed screw 70. When moving the drive member 3 from the standby position to the emergence position, the drive member 3 is moved to one side Y1 of the first direction Y. In the present embodiment, both ends of the feed screw 70 are rotatably supported by support members 78 supported by the frame 2. The linear drive mechanism 7 includes a first gear 751 fixed to the second output shaft 52 of the motor 50, a second gear 752 meshing with the first gear 751, and a third gear 753 meshing with the second gear 752 The third gear 753 is fixed to the end 709 of the feed screw 70. Therefore, the feed screw 70 is rotated about the axis L4 by the driving force of the motor 50.

（切り換え機構８の動作）
図１１は、本発明を適用した複合駆動装置１の切り換え機構８の動作を示す説明図である。なお、図１１には、矢印Ｅ１、Ｅ２で示すように、第１キャリッジ７１が第１方向Ｙの一方側Ｙ１に移動するにともなって、レバー８１の姿勢が切り換わる様子を示してある。 (Operation of switching mechanism 8)
FIG. 11 is an explanatory view showing the operation of the switching mechanism 8 of the compound drive device 1 to which the present invention is applied. Note that, as shown by arrows E1 and E2, FIG. 11 shows that the attitude of the lever 81 is switched as the first carriage 71 moves to the one side Y1 in the first direction Y.

まず、図１１に示す時間ｔ１において、被駆動部材３が待機位置にあるとき、第１キャリッジ７１およびレバー８１は、被駆動部材３の係合軸３４に対して第１方向Ｙの他方側Ｙ２にあり、レバー８１と係合軸３４とは係合していない。従って、被駆動部材３と第１キャリッジ７１との機構的な接続が解除された解除状態にある。 First, at time t1 shown in FIG. 11, when the driven member 3 is in the standby position, the first carriage 71 and the lever 81 are on the other side Y2 in the first direction Y with respect to the engagement shaft 34 of the driven member 3. And the lever 81 and the engagement shaft 34 are not engaged. Accordingly, the mechanical connection between the driven member 3 and the first carriage 71 is released, which is the release state.

次に、図１１に示す時間ｔ１１において、モータ５０が一方方向に回転し、送りねじ７０が一方方向に回転すると、第１キャリッジ７１は、矢印Ｅ１で示すように、第１方向Ｙの一方側Ｙ１に移動する。その結果、レバー８１のカム面８４がカムピン８２に押圧されて、レバー８１は、矢印Ｆ１で示すように、軸線Ｌ６周りの一方方向に回転し、斜め姿勢となる。 Next, at time t11 shown in FIG. 11, when the motor 50 rotates in one direction and the feed screw 70 rotates in one direction, the first carriage 71 is one side in the first direction Y, as indicated by the arrow E1. Move to Y1. As a result, the cam surface 84 of the lever 81 is pressed by the cam pin 82, and as shown by the arrow F1, the lever 81 rotates in one direction around the axis L6 to be in an oblique posture.

さらに、図１１に示す時間ｔ１２において、第１キャリッジ７１が第１方向Ｙの一方側Ｙ１に移動すると、レバー８１は、カムピン８２による姿勢の規制が徐々に解除され、付勢部材８８の付勢力によって、矢印Ｆ２で示すように、軸線Ｌ６周りに他方方向に回転し始める。そして、図１１に示す時間ｔ２においては、矢印Ｆ２で示すように、レバー８１が軸線Ｌ６周りに他方方向にさらに回転し、係合軸３４が凹部８１３の開放端側から凹部８１３の内側に入る。その結果、係合軸３４に対して第１方向Ｙの他方側Ｙ２に第１当接部８１４が位置し、係合軸３４に対して第１方向Ｙの一方側Ｙ１に第２当接部８１５が位置し、レバー８１と被駆動部材３とが第１方向Ｙの一方側Ｙ１および他方側Ｙ２の双方で係合した状態となる。かかる状態は、被駆動部材３と第１キャリッジ７１とが機構的に接続されて一体に移動可能な接続状態である。かかる接続状態で、第１キャリッジ７１が第１方向Ｙの一方側Ｙ１にさらに移動すると、係合軸３４は、レバー８１の第１当接部８１４によって第１方向Ｙの一方側Ｙ１に押圧されるので、被駆動部材３は、第１キャリッジ７１とともに、第１方向Ｙの一方側Ｙ１に移動し、フレーム２の開口部２０から出現する。この状態で、レバー８１の凹部８１３の開放端側は、第１キャリッジ７１の凸部７１３で塞がれる。従って、凸部７１３は、レバー８１の凹部８１３からの係合軸３４の抜けを防止する抜け止め用の凸部として機能する。 Furthermore, at time t12 shown in FIG. 11, when the first carriage 71 moves to one side Y1 in the first direction Y, the restriction of the posture by the cam pin 82 is gradually released, and the biasing force of the biasing member 88 Thus, as indicated by the arrow F2, it starts to rotate in the other direction around the axis L6. Then, at time t2 shown in FIG. 11, the lever 81 further rotates in the other direction around the axis L6 as indicated by the arrow F2, and the engagement shaft 34 enters the inside of the recess 813 from the open end side of the recess 813. . As a result, the first contact portion 814 is positioned on the other side Y2 in the first direction Y with respect to the engagement shaft 34, and the second contact portion on the one side Y1 in the first direction Y with respect to the engagement shaft 34. 815 is positioned, and the lever 81 and the driven member 3 are engaged on both the one side Y1 and the other side Y2 in the first direction Y. In this state, the driven member 3 and the first carriage 71 are mechanically connected to be integrally movable. In this connection state, when the first carriage 71 further moves to one side Y1 in the first direction Y, the engagement shaft 34 is pressed to the one side Y1 in the first direction Y by the first contact portion 814 of the lever 81. Therefore, the driven member 3 moves to the one side Y1 in the first direction Y together with the first carriage 71, and emerges from the opening 20 of the frame 2. In this state, the open end side of the concave portion 813 of the lever 81 is closed by the convex portion 713 of the first carriage 71. Accordingly, the projection 713 functions as a projection for preventing the engagement shaft 34 from coming off from the recess 813 of the lever 81.

上記の動作とは反対に、モータ５０が他方方向に回転すると、矢印Ｅ２で示すように、第１キャリッジ７１が第１方向Ｙの他方側Ｙ２に移動する。その結果、被駆動部材３の係合軸３４は、レバー８１の第２当接部８１５によって第１方向Ｙの他方側Ｙ２に押圧されるので、被駆動部材３は、第１キャリッジ７１とともに、第１方向Ｙの他方側Ｙ２に移動し、フレーム２の開口部２０からフレーム２の内側に戻る。その途中において、レバー８１は、カム機構８５によって姿勢が切り換わり、被駆動部材３と第１キャリッジ７１との接続が解除される。 Contrary to the above-described operation, when the motor 50 rotates in the other direction, the first carriage 71 moves to the other side Y2 in the first direction Y as indicated by the arrow E2. As a result, the engagement shaft 34 of the driven member 3 is pressed by the second contact portion 815 of the lever 81 to the other side Y2 in the first direction Y, so the driven member 3 together with the first carriage 71 It moves to the other side Y 2 in the first direction Y and returns from the opening 20 of the frame 2 to the inside of the frame 2. Along the way, the attitude of the lever 81 is switched by the cam mechanism 85, and the connection between the driven member 3 and the first carriage 71 is released.

（チルト駆動機構９の構成）
図１２は、本発明を適用した複合駆動装置１のチルト駆動機構９の動作を示す説明図である。図８等に示すように、ガイド部材７４の第１方向Ｙの一方側Ｚ１の端部付近には軸９１が配置されており、軸９１はフレーム２に固定されている。本形態において、軸９１は、駆動源５の駆動力によって、出現位置に到達した被駆動部材３の先端側を第２方向Ｚの一方側Ｚ１または他方側Ｚ２に傾かせるチルト駆動機構９の当接部９０として機能する。本形態では、被駆動部材３の姿勢がガイド部材７４によって規制されているため、チルト駆動機構９は、出現位置において、ガイド部材７４による被駆動部材３の姿勢の規制が解除された後、被駆動部材３の先端側を第２方向Ｚに傾かせる。 (Configuration of tilt drive mechanism 9)
FIG. 12 is an explanatory view showing the operation of the tilt drive mechanism 9 of the combined drive apparatus 1 to which the present invention is applied. As shown in FIG. 8 and the like, the shaft 91 is disposed near the end of the guide member 74 in the first direction Z1 of the first direction Y, and the shaft 91 is fixed to the frame 2. In the present embodiment, the shaft 91 is a contact of the tilt drive mechanism 9 that tilts the tip end side of the driven member 3 that has reached the appearance position to the one side Z1 or the other side Z2 in the second direction Z by the driving force of the drive source 5 It functions as the contact portion 90. In the present embodiment, since the posture of the driven member 3 is restricted by the guide member 74, the tilt drive mechanism 9 is released after the restriction of the posture of the driven member 3 by the guide member 74 is released at the appearance position. The distal end side of the drive member 3 is inclined in the second direction Z.

本形態では、軸９１がガイド部材７４の第２方向Ｚの他方側Ｚ２に配置されている。また、被駆動部材３のベース３２には、本体部３１より第２方向Ｚの他方側Ｚ２に突出した干渉部３３が設けられている。従って、図１２を参照して以下に説明するように、干渉部３３が当接部９０に第１方向Ｙの他方側Ｙ２から当接した際、被駆動部材３の先端側は、軸線Ｌ５周りに第２方向Ｚの他方側Ｚ２に傾く。 In the present embodiment, the shaft 91 is disposed on the other side Z2 of the guide member 74 in the second direction Z. Further, the base 32 of the driven member 3 is provided with an interference portion 33 which protrudes from the main body portion 31 to the other side Z2 in the second direction Z. Therefore, as described below with reference to FIG. 12, when the interference portion 33 abuts on the contact portion 90 from the other side Y2 in the first direction Y, the tip end side of the driven member 3 is around the axis L5. To the other side Z2 in the second direction Z.

図１２に示すように、被駆動部材３は、ベース３２が第１キャリッジ７１および第２キャリッジ７２に対して軸線Ｌ５周りに揺動可能に支持されている。また、図１０を参照して説明した付勢部材７６は、軸線Ｌ５周りにおいて矢印Ｓで示す方向に被駆動部材３を付勢している。従って、図１２に一点鎖線で示すように、被駆動部材３の先端側は、軸線Ｌ５周りに第２方向Ｚの一方側Ｚ１に傾こうとするが、被駆動部材３の姿勢は、図１２に実線で示すように、ガイド部材７４によって規制される。 As shown in FIG. 12, the driven member 3 is supported so that the base 32 can swing about the axis L <b> 5 with respect to the first carriage 71 and the second carriage 72. Further, the biasing member 76 described with reference to FIG. 10 biases the driven member 3 in the direction indicated by the arrow S around the axis L5. Therefore, as shown by the alternate long and short dash line in FIG. 12, the tip end side of the driven member 3 is inclined to one side Z1 of the second direction Z around the axis L5, but the posture of the driven member 3 is as shown in FIG. As shown by the solid line in FIG.

そして、矢印Ｅ１で示すように、被駆動部材３が第１方向Ｙの一方側Ｙ１に移動し、ガイド部材７４による被駆動部材３の姿勢の規制が解除されると、図１２に一点鎖線で示すように、被駆動部材３の先端側は、まず、軸線Ｌ５周りに第２方向Ｚの一方側Ｚ１に傾く。 Then, as shown by the arrow E1, when the driven member 3 is moved to one side Y1 in the first direction Y and the restriction of the posture of the driven member 3 by the guide member 74 is released, FIG. As shown, the tip end side of the driven member 3 first inclines to the one side Z1 in the second direction Z around the axis L5.

そして、被駆動部材３が第１方向Ｙの一方側Ｙ１にさらに移動すると、干渉部３３が当接部９０に第１方向Ｙの他方側Ｙ２から当接し、被駆動部材３は、図１２に実線で示す姿勢を経た後、図１２に点線で示すように、被駆動部材３の先端側は、軸線Ｌ５周りに第２方向Ｚの他方側Ｚ２に傾く。ここで、付勢部材７６は、被駆動部材３を干渉部３３が当接部９０に当接する方向に付勢しているため、被駆動部材３の先端側は、付勢部材７６の付勢力に抗して、第２方向Ｚの他方側Ｚ２に傾く。また、本形態では、被駆動部材３を傾かせる際、直動する距離が長ければ、被駆動部材３を大きく傾けることができる等、被駆動部材３の姿勢を容易に調整することができる。この場合でも、被駆動部材３の第１方向Ｙの位置は大きく変化しないので、被駆動部材３の第１方向Ｙの位置の変化については無視することができる。なお、付勢部材７６に代えて、第１キャリッジ７１と被駆動部材３との間に、被駆動部材３の干渉部３３が当接部９０に当接する方向に付勢する付勢部材を設けてもよい。 Then, when the driven member 3 is further moved to one side Y1 in the first direction Y, the interference portion 33 abuts on the contact portion 90 from the other side Y2 in the first direction Y, and the driven member 3 is shown in FIG. After passing through the posture shown by the solid line, as shown by the dotted line in FIG. 12, the tip end side of the driven member 3 is inclined to the other side Z2 of the second direction Z around the axis L5. Here, since the biasing member 76 biases the driven member 3 in the direction in which the interference portion 33 abuts on the contact portion 90, the distal end side of the driven member 3 is a biasing force of the biasing member 76. Against the other side Z2 in the second direction Z. Further, in the present embodiment, when the driven member 3 is inclined, if the distance for linear movement is long, the attitude of the driven member 3 can be easily adjusted, for example, the driven member 3 can be largely inclined. Even in this case, since the position of the driven member 3 in the first direction Y does not change significantly, the change of the position of the driven member 3 in the first direction Y can be ignored. In place of the biasing member 76, a biasing member is provided between the first carriage 71 and the driven member 3 to bias the interference portion 33 of the driven member 3 in the direction in which the interference portion 33 abuts on the abutting portion 90. May be

FIG. 13 is an explanatory view of a feed screw 70 of the combined drive system 1 to which the present invention is applied. As shown in FIG. 13, in the feed screw 70 used in the linear drive mechanism 7, a spiral groove 706 is formed on the outer peripheral surface of the round rod-like shaft 705. Here, the feed screw 70 has a first screw portion 701 provided with a spiral groove 706 at a first pitch P1, and a second screw portion 702 provided with a spiral groove 706 at a second pitch P2 shorter than the first pitch P1. , And the boundary portion 703 between the first screw portion 701 and the second screw portion 702, and in the boundary portion 703, the groove interval changes continuously in the circumferential direction. Therefore, the engaging portion 711 of the first carriage 71 has an engaging portion (not shown) with the spiral groove 706 at one position.

本形態において、送りねじ７０は、第１ねじ部７０１に対して第１方向Ｙの両側に第２ねじ部７０２を有している。第２ねじ部７０２は、被駆動部材３を待機位置から出現位置に移動させる際の初期期間と最終期間において第１キャリッジ７１を駆動する部分であり、第１ねじ部７０１は、被駆動部材３を待機位置から出現位置に移動させる際の中間期間において第１キャリッジ７１を駆動する部分である。 In the present embodiment, the feed screw 70 has second screw portions 702 on both sides in the first direction Y with respect to the first screw portion 701.

図１４は、本発明を適用した複合駆動装置１の送りねじ７０の別の構成例を示す説明図
である。図１４に示す送りねじ７０でも、図１３を参照して説明した送りねじ７０と同様、丸棒状の軸体７０７の外周側に螺旋溝７０６が設けられている。送りねじ７０は、第１ピッチＰ１で螺旋溝７０６が設けられた第１ねじ部７０１と、第１ピッチＰ１より短い第２ピッチＰ２で螺旋溝７０６が設けられた第２ねじ部７０２と、第１ねじ部７０１と第２ねじ部７０２との境界部７０３を有しており、境界部７０３では、周方向で溝の間隔が連続して変化している。このため、第１キャリッジ７１の係合部７１１は、螺旋溝７０６との係合部（図示せず）を１個所に有している。送りねじ７０は、第１ねじ部７０１に対して第１方向Ｙの両側に第２ねじ部７０２を有している。 (Another configuration example of the feed screw 70)
FIG. 14 is an explanatory view showing another configuration example of the feed screw 70 of the combined drive system 1 to which the present invention is applied. Also in the feed screw 70 shown in FIG. 14, a spiral groove 706 is provided on the outer peripheral side of the round rod-like shaft 707 as in the feed screw 70 described with reference to FIG. 13. The feed screw 70 includes a first screw portion 701 provided with a spiral groove 706 at a first pitch P1, a second screw portion 702 provided with a spiral groove 706 at a second pitch P2 shorter than the first pitch P1, and A boundary portion 703 between the first screw portion 701 and the second screw portion 702 is provided, and in the boundary portion 703, the groove interval changes continuously in the circumferential direction. Therefore, the engaging portion 711 of the first carriage 71 has an engaging portion (not shown) with the spiral groove 706 at one position. The feed screw 70 has second screw portions 702 on both sides in the first direction Y with respect to the first screw portion 701.

本形態において、螺旋溝７０６は、軸体７０７の外周面を螺旋状に巻回するように配置されたコイルばね７０８からなる。コイルばね７０８としては、線材を螺旋状に巻回した構成を採用できるとともに、図１４に示すように、軸線方向に厚さ方向を向けた板状部材を螺旋状に巻回した構成を採用することができる。 In the present embodiment, the spiral groove 706 includes a coil spring 708 arranged to spirally wind the outer peripheral surface of the shaft 707. As the coil spring 708, a configuration in which a wire is wound in a helical shape can be adopted, and as shown in FIG. 14, a configuration in which a plate-like member whose thickness direction is directed in the axial direction is spirally wound is adopted. be able to.

ここで、コイルばね７０８は、軸線方向の両側の端部７０８ａが軸体７０７と固定されている。このため、コイルばね７０８は、軸体７０７と一体に軸線周りに回転可能である。また、コイルばね７０８は、螺旋状に巻回されている部分が軸線方向に弾性をもって変形可能である。 Here, the coil spring 708 is fixed to the shaft 707 at both ends 708 a in the axial direction. For this reason, the coil spring 708 is rotatable about the axis integrally with the shaft 707. Further, the helically wound portion of the coil spring 708 is elastically deformable in the axial direction.

このように構成した送りねじ７０によれば、図１３を参照して説明した構成と違って、丸棒状の軸体の外周面に機械加工を行って螺旋溝７０６を形成する必要がないので、送りねじ７０を効率よく製造することができる。また、第１キャリッジ７１に軸線方向の外力が加わっても、かかる力は、コイルばね７０８において螺旋状に巻回されている部分が軸線方向に弾性をもって変形することによって吸収することができる。それ故、第１キャリッジ７１や周辺機構が損傷しにくい。 According to the feed screw 70 configured as described above, unlike the configuration described with reference to FIG. 13, there is no need to machine the outer peripheral surface of the round rod-like shaft to form the spiral groove 706, The feed screw 70 can be manufactured efficiently. Further, even if an external force in the axial direction is applied to the first carriage 71, the force can be absorbed by elastically deforming a portion of the coil spring 708 which is spirally wound in the axial direction. Therefore, the first carriage 71 and the peripheral mechanism are less likely to be damaged.

（複合駆動装置１全体の動作）
図１５は、本発明を適用した複合駆動装置の動作を示すタイミングチャートである。本形態の複合駆動装置１において、開閉機構６、直線駆動機構７およびチルト駆動機構９は、駆動源５が共通である。従って、図１（ａ）および図２（ａ）に示す状態から図１（ｂ）および図２（ｂ）に示す状態に移行させる際、図１５に示すように、まず、時間ｔ１からモータ５０を一方方向に回転させると、開閉機構６は、時間ｔ３までの間に開閉部材４をスライドさせ、開閉部材４に対して第２方向Ｚの一方側Ｚ１で開口部２０を開状態とする。 (Operation of the entire composite drive unit 1)
FIG. 15 is a timing chart showing the operation of the compound drive to which the present invention is applied. In the complex drive device 1 of the present embodiment, the drive source 5 is common to the opening / closing mechanism 6, the linear drive mechanism 7, and the tilt drive mechanism 9. Therefore, when shifting from the state shown in FIGS. 1A and 2A to the states shown in FIGS. 1B and 2B, first, as shown in FIG. Is rotated in one direction, the opening / closing mechanism 6 slides the opening / closing member 4 until time t3 and opens the opening 20 on the one side Z1 in the second direction Z with respect to the opening / closing member 4.

一方、直線駆動機構７では、切り換え機構８によって、第１キャリッジ７１と被駆動部材３との機構的な接続が遅れるため、時間ｔ１から遅れて、時間ｔ２から被駆動部材３を第１方向Ｙの一方側Ｙ１に向けて直動させる。そして、時間ｔ３において、被駆動部材３が出現位置に到達した後、直線駆動機構７がさらに時間ｔ４まで被駆動部材３を第１方向Ｙの一方側Ｙ１に向けて直動させると、チルト駆動機構９は、被駆動部材３の先端側を第２方向Ｚの他方側Ｚ２に向けて傾かせる。そして、被駆動部材３の姿勢の調整が終了した後、時間ｔ５においてモータ５０を停止させる。 On the other hand, in the linear drive mechanism 7, since the mechanical connection between the first carriage 71 and the driven member 3 is delayed by the switching mechanism 8, the driven member 3 is moved in the first direction Y from time t2 after time t1. Make a linear motion toward one side Y1 of When the linear drive mechanism 7 further linearly moves the driven member 3 toward the one side Y1 in the first direction Y until time t4 after the driven member 3 reaches the appearance position at time t3, tilt drive is performed. The mechanism 9 tilts the tip end side of the driven member 3 toward the other side Z2 in the second direction Z. Then, after the adjustment of the attitude of the driven member 3 is completed, the motor 50 is stopped at time t5.

その際、図１３を参照して説明したように、送りねじ７０では、被駆動部材３を待機位置から出現位置に移動させる際の初期期間と最終期間において第１キャリッジ７１が第２ねじ部７０２と係合するので、第１キャリッジ７１は低速度で移動する。これに対して、被駆動部材３を待機位置から出現位置に移動させる際の中間期間においては、第１キャリッジ７０１が第１ねじ部７０１と係合するので、第１キャリッジ７１は高速度で移動する。また、モータ５０を停止させた際、第１キャリッジ７１は第２ねじ部７０２と係合しているので、第１キャリッジ７０１はセルフロックされた状態にある。このため、モータ５
０を停止した状態で、第１キャリッジ７１に被駆動部材３の質量が作用しても、第１キャリッジ７１は移動しない。それ故、図１（ｂ）および図２（ｂ）に示す状態が維持される。なお、時間ｔ３から時間ｔ５までの間、開閉機構６では、歯車６８３ｂによって空周りするので、開閉部材４の位置は変わらない。 At that time, as described with reference to FIG. 13, in the feed screw 70, the first carriage 71 is moved by the second screw portion 702 in the initial period and the final period when moving the driven member 3 from the standby position to the emergence position. And the first carriage 71 moves at low speed. On the other hand, since the first carriage 701 is engaged with the first screw portion 701 during the intermediate period when moving the driven member 3 from the standby position to the emergence position, the first carriage 71 moves at high speed. Do. When the motor 50 is stopped, the first carriage 71 is engaged with the second screw portion 702, so that the first carriage 701 is in a self-locked state. Therefore, the motor 5
Even when the mass of the driven member 3 acts on the first carriage 71 in the state where 0 is stopped, the first carriage 71 does not move. Therefore, the state shown in FIGS. 1 (b) and 2 (b) is maintained. In addition, in the opening and closing mechanism 6, since it idles by the gear 683b from time t3 to time t5, the position of the opening and closing member 4 does not change.

また、図１（ｂ）および図２（ｂ）に示す状態から図１（ａ）および図２（ａ）に示す状態に移行させる際、まず、時間ｔ６にモータ５０が他方方向に回転し始める。その結果、直線駆動機構７は、被駆動部材３を第１方向Ｙの他方側Ｙ２に向けて直動させる。その際、直線駆動機構７が時間ｔ６から時間ｔ７まで被駆動部材３を第１方向Ｙの一方側Ｙ１に向けて直動させる間に、チルト駆動機構９は、被駆動部材３の先端側が傾いた姿勢に元に戻す。そして、直線駆動機構７がさらに時間ｔ８まで被駆動部材３を第１方向Ｙの他方側Ｙ２に向けて直動させると、開閉機構６は、時間ｔ８から時刻ｔ１０までの間において開閉部材４をスライドさせ、開口部２０を閉状態とする。その際、直線駆動機構７は、時間ｔ９まで第１キャリッジ７１を第１方向Ｙの他方側Ｙ２に向けて駆動し、被駆動部材３を第１方向Ｙの他方側Ｙ２に向けて直動させるが、時間ｔ９以降、切り換え機構８は、被駆動部材３の駆動を停止させる。なお、時間ｔ６から時間ｔ８までの間、開閉機構６では、歯車８８３ｂによって空周りするので、開閉部材４の駆動は行われない。 Further, when shifting from the state shown in FIGS. 1B and 2B to the states shown in FIGS. 1A and 2A, first, at time t6, the motor 50 starts to rotate in the other direction. . As a result, the linear drive mechanism 7 linearly moves the driven member 3 toward the other side Y2 in the first direction Y. At that time, while the linear drive mechanism 7 linearly moves the driven member 3 toward the one side Y1 in the first direction Y from time t6 to time t7, the tip end side of the driven member 3 is inclined Restore to the normal posture. Then, when the linear drive mechanism 7 linearly moves the driven member 3 toward the other side Y2 in the first direction Y until time t8, the opening / closing mechanism 6 moves the opening / closing member 4 between time t8 and time t10. The slide is made to close the opening 20. At that time, the linear drive mechanism 7 drives the first carriage 71 toward the other side Y2 in the first direction Y until time t9, and linearly moves the driven member 3 toward the other side Y2 in the first direction Y. However, after time t9, the switching mechanism 8 stops driving the driven member 3. In the opening and closing mechanism 6, since the gear 883b makes an idle rotation from time t6 to time t8, the driving of the opening and closing member 4 is not performed.

（本形態の主な効果）
以上説明したように、本形態の複合駆動装置１においては、開閉部材４による開口部２０の開閉と、被駆動部材３の待機位置と待機位置との間の第１方向Ｙでの移動とを行う場合でも、開閉機構６および直線駆動機構７では、駆動源５が共通になっている。従って、複合駆動装置１の構成の簡素化を図ることができる。また、駆動源５は、互いに反対側に向けて突出した第１出力軸５１および第２出力軸５２を備えたモータ５０である。このため、第１出力軸５１から出力される駆動力によって開閉機構６を動作させ、第２出力軸５２から出力される駆動力によって直線駆動機構７を動作させることができる。従って、モータ５０の出力を直線駆動機構７と開閉機構６とに分岐して伝達するための機構が不要である。また、本形態の複合駆動装置１には、上記の駆動源５を用いて、被駆動部材３の先端側を第２方向Ｚの一方側Ｚ１または他方側Ｚ２に傾かせるチルト駆動機構９が設けられている。このため、１つの駆動源５を用いるという簡素な構成で、開閉部材４による開口部２０の開閉、開口部２０を介しての被駆動部材３の出し入れ、および被駆動部材３の姿勢の調整を行うことができる。それ故、被駆動部材３が表示部材３０である場合、利用者は、表示部材３０の姿勢を画像を見やすい姿勢に調整することができる。 (Main effects of this form)
As described above, in the compound drive device 1 of the present embodiment, the opening and closing of the opening 20 by the opening and closing member 4 and the movement of the driven member 3 in the first direction Y between the standby position and the standby position Even in this case, the drive source 5 is common to the open / close mechanism 6 and the linear drive mechanism 7. Therefore, the configuration of the compound drive device 1 can be simplified. Further, the drive source 5 is a motor 50 provided with a first output shaft 51 and a second output shaft 52 protruding toward opposite sides. Therefore, the opening / closing mechanism 6 can be operated by the driving force output from the first output shaft 51, and the linear driving mechanism 7 can be operated by the driving force output from the second output shaft 52. Therefore, a mechanism for branching and transmitting the output of the motor 50 to the linear drive mechanism 7 and the opening / closing mechanism 6 is unnecessary. Further, the compound drive device 1 of the present embodiment is provided with a tilt drive mechanism 9 which tilts the tip end of the driven member 3 to the one side Z1 or the other side Z2 in the second direction Z using the above-mentioned drive source 5. It is done. Therefore, the opening and closing of the opening 20 by the opening and closing member 4, the insertion and removal of the driven member 3 through the opening 20, and the adjustment of the posture of the driven member 3 are performed with a simple configuration using one drive source 5. It can be carried out. Therefore, when the driven member 3 is the display member 30, the user can adjust the posture of the display member 30 to a posture in which the image can be easily viewed.

また、本形態において、開閉機構６は、開閉部材４を第２方向Ｚにスライドさせて開閉部材４の第２方向Ｚの一方側Ｚ１で開口部２０を開状態とする。このため、被駆動部材３が出現する側に開閉部材４が突出しないので、開閉部材４の存在が邪魔になりにくい。また、開状態では、第１部材４１と第２部材４２とが重なった状態となるため、開状態において開閉部材４の第２方向Ｚの寸法が小さくなる。それ故、開閉部材４の存在が邪魔になりにくい。 Further, in the present embodiment, the opening and closing mechanism 6 slides the opening and closing member 4 in the second direction Z to open the opening 20 on one side Z1 of the opening and closing member 4 in the second direction Z. For this reason, since the opening and closing member 4 does not protrude to the side where the driven member 3 appears, the presence of the opening and closing member 4 is unlikely to be an obstacle. Further, in the open state, the first member 41 and the second member 42 overlap each other, so that the dimension of the opening / closing member 4 in the second direction Z decreases in the open state. Therefore, the presence of the opening / closing member 4 is unlikely to be an obstacle.

また、チルト駆動機構９では、ガイド部材７４による被駆動部材３の姿勢の規制が解除された後、直線駆動機構７が被駆動部材３をさらに出現位置に向けて駆動した際に被駆動部材３と当接部９０とを第１方向Ｙで当接させて被駆動部材３の先端側を第２方向Ｚに傾かせる構成が採用されている。従って、被駆動部材３の直動を利用して被駆動部材３の姿勢を切り換えるため、チルト駆動機構９の構成の簡素化を図ることができる。また、被駆動部材３を傾かせる際、直動する距離が長ければ、被駆動部材３を大きく傾けることができる等、被駆動部材３の姿勢を容易に調整することができる。また、被駆動部材３は、出現位置に移動した際にフレーム２から突出する本体部３１と、本体部３１より第２方向Ｚに突出してフレーム２の内側で当接部９０と当接する干渉部３３とを備えている。このた
め、比較的簡素な構成で被駆動部材３の姿勢を切り換えることができる。 Further, in the tilt drive mechanism 9, when the linear drive mechanism 7 drives the driven member 3 further toward the appearance position after the restriction of the posture of the driven member 3 by the guide member 74 is released, the driven member 3 And the abutting portion 90 are abutted in the first direction Y, and the tip end side of the driven member 3 is inclined in the second direction Z. Therefore, since the posture of the driven member 3 is switched by utilizing the linear movement of the driven member 3, the structure of the tilt drive mechanism 9 can be simplified. Further, when the driven member 3 is inclined, if the linear movement distance is long, the posture of the driven member 3 can be easily adjusted, for example, the driven member 3 can be largely inclined. Further, when the driven member 3 moves to the appearance position, the driven member 3 protrudes from the frame 2, and the interference portion protrudes from the main body 31 in the second direction Z and contacts the contact portion 90 inside the frame 2. And 33. Therefore, the attitude of the driven member 3 can be switched with a relatively simple configuration.

また、ガイド部材７４は、被駆動部材３に第２方向Ｚの他方側Ｚ２から接する第１ガイド部７４１と、被駆動部材３に第２方向Ｚの一方側Ｚ１から接する第２ガイド部７４２とを有している。従って、ガイド部材７４は、被駆動部材３を適正な姿勢で直動させることができる。また、ガイド部材７４は、第１ガイド部７４１の第１方向Ｙの一方側Ｙ１で先端側が第２方向Ｚの他方側Ｚ２に傾いた第１支持部７４１ａと、第２ガイド部７４２の第１方向Ｙの一方側Ｙ１で先端側が第２方向Ｚの一方側Ｚ１に傾いた第２支持部７４２ａとを有している。このため、被駆動部材が外部からの振動等によって第２方向Ｚに過度に傾くことを抑制することができる。 Further, the guide member 74 includes a first guide portion 741 in contact with the driven member 3 from the other side Z2 in the second direction Z, and a second guide portion 742 in contact with the driven member 3 from the one side Z1 in the second direction Z. have. Therefore, the guide member 74 can linearly move the driven member 3 in an appropriate posture. Further, the guide member 74 is provided with a first support portion 741a whose front end side is inclined to the other side Z2 in the second direction Z on the one side Y1 of the first guide portion 741 in the first direction Y; The one side Y1 of the direction Y has a second support portion 742a whose front end side is inclined to the one side Z1 of the second direction Z. Therefore, it is possible to prevent the driven member from being excessively inclined in the second direction Z due to vibration or the like from the outside.

また、チルト駆動機構９は、被駆動部材３の先端側を第２方向Ｚの他方側Ｚ２に傾かせる構成である。このため、被駆動部材３が傾いた側には開閉部材４が位置するが、このような場合でも、本形態では、被駆動部材３が出現する側に開閉部材４が突出しないので、開閉部材４の存在が邪魔になりにくい。 The tilt drive mechanism 9 is configured to tilt the tip end side of the driven member 3 to the other side Z2 in the second direction Z. Therefore, the open / close member 4 is positioned on the side to which the driven member 3 is inclined, but even in this case, in the present embodiment, the open / close member 4 does not project to the side where the driven member 3 appears. The presence of 4 is less likely to get in the way.

また、直線駆動機構７において、第２キャリッジ７２と被駆動部材３との間には、被駆動部材３の干渉部３３を当接部９０に当接する方向に付勢する付勢部材７６が設けられているため、チルト駆動機構９を確実に動作させることができる。 Further, in the linear drive mechanism 7, an urging member 76 is provided between the second carriage 72 and the driven member 3 for urging the interference portion 33 of the driven member 3 in a direction to abut on the abutting portion 90. Therefore, the tilt drive mechanism 9 can be operated reliably.

さらに、直線駆動機構７には切り換え機構８が設けられているため、第１キャリッジ７１が移動を開始した場合でも、被駆動部材３の直動を遅らせることができる。従って、被駆動部材３を開口部２０から外側に出現させる際、被駆動部材３と開閉部材４との干渉を抑制することができる。また、切り換え機構８は、レバー８１およびカム機構８５を有しているため、比較的簡素な構成で、被駆動部材３と第１キャリッジ７１との接続を切り換えることができる。 Furthermore, since the linear drive mechanism 7 is provided with the switching mechanism 8, the linear motion of the driven member 3 can be delayed even when the first carriage 71 starts moving. Therefore, when causing the driven member 3 to appear outward from the opening 20, interference between the driven member 3 and the opening / closing member 4 can be suppressed. Further, since the switching mechanism 8 includes the lever 81 and the cam mechanism 85, the connection between the driven member 3 and the first carriage 71 can be switched with a relatively simple configuration.

また、開閉機構６は、閉状態では第１部材４１が第２部材４２に対して第２方向Ｚに並んだ状態とし、開状態では第１部材４１と第２部材４２とを第１方向Ｙで重なった状態で第２方向Ｚの他方側Ｚ２の端部４１ａ、４２ａがフレーム２内に引き込まれた斜め姿勢とする。このため、開閉部材４の存在が邪魔になりにくい。 In the open / close mechanism 6, the first member 41 is aligned with the second member 42 in the second direction Z in the closed state, and in the open state, the first member 41 and the second member 42 in the first direction Y And the end portions 41a and 42a of the other side Z2 in the second direction Z are in a diagonal posture drawn into the frame 2. For this reason, the presence of the opening / closing member 4 is unlikely to be an obstacle.

また、開閉機構６は、ピニオン６２、第１ラック４１０および第２ラック４２０によって第１部材４１および第２部材４２を第２方向Ｚに沿ってスライドさせるため、比較的簡素な構成で、第１部材４１と第２部材４２とが第２方向Ｚに並んだ閉状態と、第１部材４１と第２部材４２とが第１方向Ｙで重なった開状態とを実現することができる。 In addition, since the opening and closing mechanism 6 slides the first member 41 and the second member 42 along the second direction Z by the pinion 62, the first rack 410 and the second rack 420, the first structure is relatively simple. A closed state in which the member 41 and the second member 42 are aligned in the second direction Z and an open state in which the first member 41 and the second member 42 overlap in the first direction Y can be realized.

また、開閉機構６は、歯車伝達機構６８に歯車６８３ｂを含んでいるため、開閉部材４に開閉動作を行わせた後、被駆動部材３の駆動を継続する一方、開閉部材４の駆動については停止することができる。それ故、共通の駆動源５によって複数の機構を作動させるのに適している。 In addition, since the opening / closing mechanism 6 includes the gear 683b in the gear transmission mechanism 68, the driving of the driven member 3 is continued after the opening / closing member 4 performs the opening / closing operation, while the driving of the opening / closing member 4 is It can be stopped. Therefore, it is suitable to operate a plurality of mechanisms by the common drive source 5.
