図２は、プロジェクタ機能を有するカメラのカメラボディに設けられている撮影レンズバリア機構及びプロジェクタレンズバリア機構の構成を示す断面図である。撮影レンズ２０が備えられている撮影鏡筒４は、固定筒２２の内側にカム筒２４が配置され、カム筒２４の内側に１群筒２６が配置され、１群筒２６の内側に更に直進筒（直進駆動部材）２８が配置されている。ここで直進筒２８のカメラボディ側の端部には、後述の直進連動部材３２に、直進筒２８の撮影レンズ２０の光軸方向への駆動力を伝達するための突起部２８ａが形成されている。固定筒２２の内壁面にはカム溝が形成されておりカム筒２４の外壁面に形成されたカムがカム溝に係合している。またカム筒２４の内壁面にはカム溝が形成されており１群筒２６の外壁面に形成されたカムがカム溝に係合している。更に直進筒２８はカム筒２４と直進方向にのみ連結されており固定筒２２に直進ガイドされている。   FIG. 2 is a cross-sectional view showing a configuration of a photographing lens barrier mechanism and a projector lens barrier mechanism provided in a camera body of a camera having a projector function. In the photographic lens barrel 4 provided with the photographic lens 20, a cam cylinder 24 is arranged inside the fixed cylinder 22, a first group cylinder 26 is arranged inside the cam cylinder 24, and further advances straight inside the first group cylinder 26. A cylinder (straight drive member) 28 is disposed. Here, a projecting portion 28a for transmitting a driving force in the optical axis direction of the photographic lens 20 of the rectilinear barrel 28 is formed on an end portion of the rectilinear barrel 28 on the camera body side, which will be described later. Yes. A cam groove is formed on the inner wall surface of the fixed cylinder 22, and a cam formed on the outer wall surface of the cam cylinder 24 is engaged with the cam groove. A cam groove is formed on the inner wall surface of the cam cylinder 24, and a cam formed on the outer wall surface of the first group cylinder 26 is engaged with the cam groove. Further, the rectilinear cylinder 28 is connected to the cam cylinder 24 only in the rectilinear direction, and is linearly guided to the fixed cylinder 22.

１群筒２６の先端部分には台座２６ａが設けられており、台座２６ａにより撮影レンズ２０を保持すると共に鏡筒バリアリング３０が支持されている。また鏡筒バリアリング３０上には、ボス６ａを介して撮影レンズバリア６が保持されている。   A pedestal 26a is provided at the tip of the first group cylinder 26, and the lens barrel barrier ring 30 is supported by the pedestal 26a to hold the photographing lens 20. On the barrel barrier ring 30, the taking lens barrier 6 is held via a boss 6a.

また、プロジェクタユニットのプロジェクタレンズ３６は、台座３８により保持されている。台座３８上にはプロジェクタバリアリング３４が保持されており、プロジェクタバリアリング３４上にはボス１０ａを介してプロジェクタレンズバリア１０が保持されている。また、台座３８のカメラボディの内側には、直進筒２８の撮影レンズ２０の光軸方向への駆動力をプロジェクタバリアリング３４へ伝達するための直進連動部材３２が配置されている。   The projector lens 36 of the projector unit is held by a pedestal 38. A projector barrier ring 34 is held on the pedestal 38, and the projector lens barrier 10 is held on the projector barrier ring 34 via a boss 10a. Further, a rectilinear interlocking member 32 for transmitting a driving force in the optical axis direction of the photographic lens 20 of the rectilinear barrel 28 to the projector barrier ring 34 is disposed inside the camera body of the pedestal 38.

この第１の実施形態に係るカメラ２においては、電源ＯＦＦ時には、図２に示すように撮影鏡筒４が沈胴状態となり撮影レンズバリア６及びプロジェクタレンズバリア１０が共に閉じた状態となる。ここでカメラ２の電源スイッチ１２を操作し、カメラ２の電源をＯＮすると共に、モード切替ボタン１６を操作し撮影モードを選択した場合には、図示しないモータの駆動力によりカム筒２４を回転させる。これにより図３に示すように、カム筒２４が回転しながら繰出され、１群筒２６及び直進筒２８も撮影レンズ２０の光軸方向に繰出される。この際に直進筒２８の先端部２８ａと鏡筒バリアリング３０のカメラボディに対向した面に形成されているリブ３０ａとが離れた状態になり、鏡筒バリアリング３０が回転して撮影レンズバリア６が開く。一方、直進連動部材３２の先端部３２ｂは、プロジェクタバリアリング３４のカメラボディに対向した面に形成されているリブ３４ａを押した状態であるため、プロジェクタレンズバリア１０は閉じたままである。   In the camera 2 according to the first embodiment, when the power is turned off, as shown in FIG. 2, the photographic lens barrel 4 is retracted and both the photographic lens barrier 6 and the projector lens barrier 10 are closed. Here, when the power switch 12 of the camera 2 is operated to turn on the power of the camera 2 and the shooting mode is selected by operating the mode switching button 16, the cam cylinder 24 is rotated by the driving force of a motor (not shown). . As a result, as shown in FIG. 3, the cam cylinder 24 is extended while rotating, and the first group cylinder 26 and the rectilinear cylinder 28 are also extended in the optical axis direction of the photographing lens 20. At this time, the distal end portion 28a of the rectilinear tube 28 and the rib 30a formed on the surface of the lens barrel barrier ring 30 facing the camera body are separated from each other, and the lens barrel barrier ring 30 rotates to rotate the photographing lens barrier. 6 opens. On the other hand, since the leading end portion 32b of the rectilinear interlocking member 32 is in a state where the rib 34a formed on the surface of the projector barrier ring 34 facing the camera body is pressed, the projector lens barrier 10 remains closed.

カメラ２のモード切替ボタン１６を操作しプロジェクタモードを選択した場合には、図示しないモータの駆動力によりカム筒２４を回転させることによりカム筒２４が回転しながら繰込まれ、１群筒２６及び直進筒２８も撮影レンズ２０の光軸方向に繰込まれて図２に示す電源ＯＦＦ状態になる。この際に直進筒２８の先端部２８ａにより鏡筒バリアリング３０のリブ３０ａが押され、鏡筒バリアリング３０が回転して撮影レンズバリア６が閉じる。このとき直進連動部材３２の先端部３２ｂは、プロジェクタバリアリング３４のリブ３４ａを押した状態であるため、プロジェクタレンズバリア１０は閉じたままである。   When the projector 2 is operated by operating the mode switching button 16 of the camera 2, the cam cylinder 24 is rotated by the driving force of a motor (not shown) so that the cam cylinder 24 is rotated while being rotated. The rectilinear cylinder 28 is also retracted in the direction of the optical axis of the taking lens 20 and is turned off as shown in FIG. At this time, the rib 30a of the lens barrel barrier ring 30 is pushed by the distal end portion 28a of the rectilinear tube 28, and the lens barrel barrier ring 30 rotates to close the photographing lens barrier 6. At this time, the leading end portion 32b of the rectilinear interlocking member 32 is in a state in which the rib 34a of the projector barrier ring 34 is pressed, so that the projector lens barrier 10 remains closed.

プロジェクタモードを選択した場合には、図４に示すように、図２に示す電源ＯＦＦ時よりも更に直進筒２８が繰込まれ、直進筒２８の突起部２８ａにより直進連動部材３２の基底部３２ａをカメラボディの内側方向へ押し込む。これにより直進連動部材３２の先端部３２ｂとプロジェクタバリアリング３４のリブ３４ａとが離れた状態になり、プロジェクタバリアリング３４が回転してプロジェクタレンズバリア１０が開く。   When the projector mode is selected, as shown in FIG. 4, the rectilinear cylinder 28 is further retracted than when the power is turned off as shown in FIG. 2, and the base portion 32 a of the rectilinear interlocking member 32 is caused by the protrusion 28 a of the rectilinear cylinder 28. Press inward on the camera body. As a result, the distal end portion 32b of the rectilinear interlocking member 32 and the rib 34a of the projector barrier ring 34 are separated, and the projector barrier ring 34 rotates to open the projector lens barrier 10.

この第１の実施形態に係る撮影レンズバリア機構及びプロジェクタレンズバリア機構によれば、撮影鏡筒の直進筒の撮影レンズの光軸方向への直進駆動力を用いて、撮影レンズバリア及びプロジェクタレンズバリアの開閉を行うことができるため、撮影レンズバリア機構及びプロジェクタレンズバリア機構の小型化を図ることができる。   According to the photographic lens barrier mechanism and the projector lens barrier mechanism according to the first embodiment, the photographic lens barrier and the projector lens barrier are used by using the straight driving force in the optical axis direction of the photographic lens of the photographic lens barrel. Therefore, the photographing lens barrier mechanism and the projector lens barrier mechanism can be downsized.

次に図５〜図７を参照して、本発明の第２の実施形態について説明する。なお、第２の実施形態の説明においては、第１の実施形態のカメラの構成と同一の構成には、第１の実施形態の説明で用いたのと同一の符号を用いて説明する。この第２の実施形態は、第１の実施形態において、撮影レンズバリアが開きプロジェクタレンズバリアが閉じた撮影状態と、撮影レンズバリアとプロジェクタレンズバリアとが共に閉じた収納状態（電源ＯＦＦ状態）と、撮影レンズバリアが閉じプロジェクタレンズバリアが開いた投影状態とを有していたのを、撮影レンズバリアとプロジェクタレンズバリアとが共に閉じた収納状態（電源ＯＦＦ状態）と、撮影レンズバリアが開きプロジェクタレンズバリアが閉じた第１撮影状態と、撮影レンズバリアとプロジェクタレンズバリアとが共に開いた第２撮影状態とを有するように変更したものである。   Next, a second embodiment of the present invention will be described with reference to FIGS. In the description of the second embodiment, the same reference numerals as those used in the description of the first embodiment are used for the same configurations as those of the camera of the first embodiment. In the second embodiment, in the first embodiment, an imaging state in which the imaging lens barrier is opened and the projector lens barrier is closed, and a storage state (power OFF state) in which the imaging lens barrier and the projector lens barrier are both closed. The projection lens barrier is closed and the projector lens barrier is opened, and the projection lens barrier and the projector lens barrier are both closed. The first imaging state in which the lens barrier is closed and the second imaging state in which the imaging lens barrier and the projector lens barrier are both opened are changed.

即ち、図５に示す収納状態（電源ＯＦＦ状態）から、図６に示す第１撮影状態に移行する場合には、第１の実施形態と同様にして、カム筒２４の回転により、カム筒２４、１群筒２６及び直進筒２８が繰り出され、撮影レンズバリア６が開く。この際に直進筒２８に設けられた突起部２８ａは、直進連動部材３２０の基底部３２０ａに接触しておらず、また直進連動部材３２０の先端部３２０ｂは、プロジェクタバリアリング３４のリブ３４ａと接触しておらずプロジェクタレンズバリア１０が閉じている。なお、この第２の実施形態においては、第１の実施形態と異なり、直進連動部材３２０の先端部３２０ｂによりプロジェクタバリアリング３４のリブ３４ａを押すと、プロジェクタバリアリング３４が回転してプロジェクタレンズバリア１０が開くように構成されている。   That is, when the storage state (power supply OFF state) shown in FIG. 5 shifts to the first photographing state shown in FIG. 6, the cam cylinder 24 is rotated by the rotation of the cam cylinder 24 in the same manner as in the first embodiment. The first group cylinder 26 and the rectilinear cylinder 28 are extended, and the photographing lens barrier 6 is opened. At this time, the projecting portion 28 a provided on the rectilinear cylinder 28 is not in contact with the base portion 320 a of the rectilinear interlocking member 320, and the tip end portion 320 b of the rectilinear interlocking member 320 is in contact with the rib 34 a of the projector barrier ring 34. The projector lens barrier 10 is not closed. In the second embodiment, unlike the first embodiment, when the rib 34a of the projector barrier ring 34 is pushed by the tip portion 320b of the rectilinear interlocking member 320, the projector barrier ring 34 rotates and the projector lens barrier is rotated. 10 is configured to open.

図６に示す第１撮影状態から図７に示す第２撮影状態に移行する場合には、カム筒２４の回転により、直進筒２８が更に微小距離繰出され、直進筒２８に設けられた突起部２８ａにより直進連動部材３２０の基底部３２０ａが押され、直進連動部材３２０の先端部３２０ｂによりプロジェクタバリアリング３４のリブ３４ａが押される。これによりプロジェクタバリアリング３４が回転してプロジェクタレンズバリア１０が開く。   When shifting from the first shooting state shown in FIG. 6 to the second shooting state shown in FIG. 7, the rectilinear cylinder 28 is further extended by a small distance by the rotation of the cam cylinder 24, and the protrusion provided on the rectilinear cylinder 28. The base part 320a of the rectilinear interlocking member 320 is pushed by 28a, and the rib 34a of the projector barrier ring 34 is pushed by the tip part 320b of the rectilinear interlocking member 320. As a result, the projector barrier ring 34 rotates and the projector lens barrier 10 opens.

従って、この第２の実施形態によれば、撮影鏡筒の直進筒の撮影レンズの光軸方向への直進駆動力を用いて、撮影レンズバリア及びプロジェクタレンズバリアの開閉を行うことができるため、撮影レンズバリア機構及びプロジェクタレンズバリア機構の小型化を図ることができる。また撮影を行いながらプロジェクタ投影を行うことができる。   Therefore, according to the second embodiment, the photographing lens barrier and the projector lens barrier can be opened and closed by using the rectilinear driving force in the optical axis direction of the photographing lens of the photographing lens barrel. The photographing lens barrier mechanism and the projector lens barrier mechanism can be reduced in size. Projector projection can be performed while shooting.

次に図８〜図１０を参照して、本発明の第３の実施形態について説明する。なお、第３の実施形態の説明においては、第１の実施形態のカメラの構成と同一の構成には、第１の実施形態の説明で用いたのと同一の符号を用いて説明する。この第３の実施形態は、第１の実施形態において、直進筒の直進駆動力を用いて撮影レンズバリアとプロジェクタレンズバリアの開閉駆動を行っていたのを、カム筒の回転駆動力を用いて撮影レンズバリアとプロジェクタレンズバリアの開閉駆動を行うようにしたものである。   Next, a third embodiment of the present invention will be described with reference to FIGS. In the description of the third embodiment, the same reference numerals as those used in the description of the first embodiment are used for the same configurations as those of the camera of the first embodiment. In the third embodiment, the shooting lens barrier and the projector lens barrier are opened / closed using the straight driving force of the straight cylinder in the first embodiment, but the rotational driving force of the cam cylinder is used. The photographing lens barrier and the projector lens barrier are opened and closed.

図８に示すように、鏡筒駆動モータ４０の回転力をカム筒（回転駆動部材）２４に伝達するための第１鏡筒駆動ギア４２、第２鏡筒駆動ギア４４、第３鏡筒駆動ギア４６及び第４鏡筒駆動ギア４８が設けられている。また、第４鏡筒駆動ギア４８の回転力をプロジェクタバリアリング３４に伝達するためのプロジェクタバリア駆動ギア５０が設けられている。図８に示す電源ＯＦＦ状態から撮影状態に移行する場合には、図９に示すように鏡筒駆動モータ４０の回転力を第１鏡筒駆動ギア４２、第２鏡筒駆動ギア４４、第３鏡筒駆動ギア４６及び第４鏡筒駆動ギア４８を介してカム筒２４に伝達し、カム筒２４、１群筒２６及び直進筒３８を繰出すことにより撮影レンズバリア６を開く。   As shown in FIG. 8, a first lens barrel drive gear 42, a second lens barrel drive gear 44, and a third lens barrel drive for transmitting the rotational force of the lens barrel drive motor 40 to the cam barrel (rotation drive member) 24. A gear 46 and a fourth lens barrel drive gear 48 are provided. In addition, a projector barrier drive gear 50 for transmitting the rotational force of the fourth lens barrel drive gear 48 to the projector barrier ring 34 is provided. When shifting from the power-off state shown in FIG. 8 to the photographing state, as shown in FIG. 9, the rotational force of the lens barrel drive motor 40 is changed to the first lens barrel drive gear 42, the second lens barrel drive gear 44, and the third. This is transmitted to the cam barrel 24 via the lens barrel drive gear 46 and the fourth lens barrel drive gear 48, and the photographing lens barrier 6 is opened by extending the cam barrel 24, the first group barrel 26, and the rectilinear barrel 38.

また、撮影状態から投影状態に移行する場合には、図１０に示すように、鏡筒駆動モータ４０の回転力によりカム筒２４を回転させて、カム筒２４、１群筒２６及び直進筒２８を繰込み、撮影レンズバリア６を閉じ、更に鏡筒駆動モータ４０の回転力を第４鏡筒駆動ギア４８及びプロジェクタバリア駆動ギア５０を介してプロジェクタバリアリング３４に伝達して、プロジェクタレンズバリア１０を開く。   When shifting from the photographing state to the projection state, as shown in FIG. 10, the cam barrel 24 is rotated by the rotational force of the lens barrel drive motor 40, and the cam barrel 24, the first group barrel 26, and the rectilinear barrel 28. , The photographing lens barrier 6 is closed, and the rotational force of the lens barrel driving motor 40 is further transmitted to the projector barrier ring 34 via the fourth lens barrel driving gear 48 and the projector barrier driving gear 50, and the projector lens barrier 10. open.
