Description

本発明は、例えばレンズ交換式カメラのカメラ本体に設けられる発光装置に関し、より詳しくは発光装置をカメラ本体内に収納するための構造に関する。   The present invention relates to a light emitting device provided in a camera body of, for example, an interchangeable lens camera, and more particularly to a structure for housing the light emitting device in the camera body.

従来レンズ交換式カメラの発光装置は、不使用時にはカメラ本体内に収納され、使用時にはカメラ本体からポップアップするように構成されている。発光装置のポップアップ高さは、カメラ本体から前方に突出する撮影レンズによって発光装置からの照明光が遮られる、いわゆるケラレが生じることがないよう、できるだけ大きいことが好ましい。カメラ本体に対してポップアップするように連結された発光装置として、例えば特許文献１、２に開示されたものが知られている。   Conventionally, the light emitting device of the interchangeable lens camera is configured to be housed in the camera body when not in use and to pop up from the camera body when in use. The pop-up height of the light emitting device is preferably as large as possible so that the illuminating light from the light emitting device is not blocked by the photographing lens protruding forward from the camera body. As light emitting devices connected so as to pop up with respect to the camera body, for example, those disclosed in Patent Documents 1 and 2 are known.

特許文献１に開示された発光装置が設けられたカメラはレンズ交換式ではなくコンパクトカメラであるため、カメラ本体内の制約が少なく、カメラ本体内にコンパクトに収納することができる。これに対して特許文献２に開示された発光装置では、ポップアップのための支持機構が大きいために、発光装置の収納部はカメラ本体の上面から大きく突出するという問題がある。   Since the camera provided with the light emitting device disclosed in Patent Document 1 is not a lens interchangeable type but a compact camera, there are few restrictions in the camera body, and the camera body can be stored compactly. On the other hand, the light emitting device disclosed in Patent Document 2 has a problem that the support mechanism for the pop-up is large, so that the housing portion of the light emitting device protrudes greatly from the upper surface of the camera body.

本発明は、レンズ交換式カメラにおいて、発光装置のポップアップの高さを十分に大きくすることができる支持機構であっても、カメラ本体内にコンパクトに収納することができる発光装置の収納構造を提供することを目的としている。   The present invention provides a storage structure for a light-emitting device that can be stored compactly in the camera body even if the support mechanism can sufficiently increase the pop-up height of the light-emitting device in the interchangeable lens camera. The purpose is to do.

本発明に係る発光装置の収納構造は、前面にレンズ鏡筒を装着するためのレンズマウントが形成されるとともに、背面側に、レンズマウントの中央部に中心が位置するようにして撮像素子が配置されたカメラ本体と、レンズマウントの上部に形成され、発光装置が出没自在に取付けられる収納凹部とを備え、収納凹部の内側底面が、レンズマウントの上側縁部に設けられた係合爪の下縁と撮像素子の撮像領域の上辺との間に位置することを特徴としている。   In the light emitting device housing structure according to the present invention, a lens mount for mounting a lens barrel is formed on the front surface, and an imaging element is disposed on the rear surface side so that the center is located at the center of the lens mount. And a storage recess formed in the upper portion of the lens mount, in which the light emitting device can be freely inserted and retracted, and the inner bottom surface of the storage recess is below the engaging claw provided on the upper edge of the lens mount. It is characterized by being located between the edge and the upper side of the imaging area of the imaging device.

収納凹部と、収納凹部に収納された状態にある発光装置の全てがレンズマウントよりもカメラ本体の背面側に位置することが好ましい。この構成によれば、カメラ本体をより小さくすることができる。   It is preferable that all of the storage recess and the light emitting device stored in the storage recess are located on the back side of the camera body with respect to the lens mount. According to this configuration, the camera body can be made smaller.

収納凹部に収納された状態にある発光装置の上面は、カメラ本体の上面に設けられた発光装置以外の部材、例えばモードダイアルと略同じ高さである。すなわち収納状態にある発光装置がカメラ本体の他の部材よりも大きく突出することはない。   The upper surface of the light emitting device that is housed in the housing recess is substantially the same height as a member other than the light emitting device provided on the upper surface of the camera body, for example, a mode dial. That is, the light emitting device in the housed state does not protrude larger than the other members of the camera body.

カメラ本体を正面から見たときの収納凹部の幅はレンズマウントの幅よりも小さいことが好ましい。また収納凹部に収納された状態にある発光装置の高さは、カメラ本体内に設けられる暗箱の高さよりも小さい。さらにレンズマウントの上端を基準として見た場合に、上端から収納凹部の内側底面までの高さが上端から発光装置の上面までの高さよりも大きいことが好ましい。収納凹部の下端部が撮像素子の撮像領域にできるだけ近づくように、収納凹部の内側底面を下方に位置させることも可能である。   The width of the storage recess when the camera body is viewed from the front is preferably smaller than the width of the lens mount. The height of the light emitting device in the state of being housed in the housing recess is smaller than the height of the dark box provided in the camera body. Further, when viewed from the upper end of the lens mount, it is preferable that the height from the upper end to the inner bottom surface of the housing recess is larger than the height from the upper end to the upper surface of the light emitting device. It is also possible to position the inner bottom surface of the storage recess downward so that the lower end of the storage recess is as close as possible to the imaging region of the image sensor.

好ましくは発光装置をカメラ本体に取付けるための支持機構は、カメラ本体に、第１支持部において枢支された第１のアームと、第１のアームの先端に、第２支持部において回動自在に連結された連結部材と、連結部材において、第２支持部とは異なる第３支持部において回動自在に連結され、発光部を有する発光ブロックが取付けられた発光ブロック支持部材とを備え、第１のアームと連結部材と発光ブロック支持部材とをカメラ本体の収納凹部に収納した状態において、第１のアームと発光ブロック支持部材は平行状態になり、発光部は第１支持部に近接する。   Preferably, the support mechanism for attaching the light emitting device to the camera body includes a first arm pivotally supported by the first support part, a tip of the first arm, and a second support part that is pivotable at the second support part. And a light-emitting block support member that is rotatably connected to a third support portion different from the second support portion and to which a light-emitting block having a light-emitting portion is attached. In a state where the one arm, the connecting member, and the light emitting block support member are housed in the housing recess of the camera body, the first arm and the light emitting block support member are in a parallel state, and the light emitting portion is close to the first support portion.

また本発明に係る第２の発光装置の収納構造は、レンズ鏡筒を装着するためのレンズマウントが形成されるとともに、背面側に、レンズマウントの中央部に中心が位置するようにして撮像素子が配置されたカメラ本体と、レンズマウントの上部に形成され、発光装置が出没自在に取付けられる収納凹部とを備え、レンズマウントの上端を基準として見た場合に、上端から収納凹部の内側底面までの高さが上端から発光装置の上面までの高さよりも大きいことを特徴としている。   According to the second light emitting device housing structure of the present invention, the lens mount for mounting the lens barrel is formed, and the image pickup element is arranged so that the center is located at the center of the lens mount on the back side. From the upper end to the inner bottom surface of the storage recess when viewed from the upper end of the lens mount. Is higher than the height from the upper end to the upper surface of the light emitting device.

本発明によれば、レンズ交換式カメラにおいて、発光装置のポップアップの高さを十分に大きくすることができる支持機構であっても、カメラ本体内にコンパクトに収納することができる。   According to the present invention, in the interchangeable lens camera, even a support mechanism capable of sufficiently increasing the pop-up height of the light emitting device can be stored compactly in the camera body.

以下、本発明の一実施形態を図面を参照して説明する。
図１はレンズ交換式カメラの外観を示し、カメラ本体１０からレンズ鏡筒を外した状態を示している。このカメラはいわゆるミラーレスタイプであり、光学ファインダは設けられておらず、被写体像はカメラ本体１０の背面に設けられたモニタに表示される。カメラ本体１０の上面には、撮影モード等を選択するためのモードダイアル１１が設けられ、モードダイアル１１の横には発光装置３０が設けられる。またカメラ本体１０の上面には、発光装置３０をポップアップさせるための発光ボタン３９（図３参照）が設けられる。なお図１において発光装置３０はカメラ本体１０内に収納された状態にある。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows the appearance of an interchangeable lens camera, and shows a state in which the lens barrel is removed from the camera body 10. This camera is a so-called mirrorless type, is not provided with an optical viewfinder, and the subject image is displayed on a monitor provided on the back of the camera body 10. A mode dial 11 for selecting a shooting mode or the like is provided on the upper surface of the camera body 10, and a light emitting device 30 is provided beside the mode dial 11. A light emitting button 39 (see FIG. 3) for popping up the light emitting device 30 is provided on the upper surface of the camera body 10. In FIG. 1, the light emitting device 30 is housed in the camera body 10.

カメラ本体１０の前面には、レンズ鏡筒を装着するためのレンズマウント１２が形成される。レンズマウント１２は円形を呈し、カメラ本体１０を正面から見ると光学装置３０の真下に位置する。レンズマウント１２には、カメラ本体１０内の制御システムとレンズ鏡筒内の制御システムとの間においてデータ通信等を行うための接点１３、レンズ鏡筒を取付けるための爪１４等が設けられる。   A lens mount 12 for mounting a lens barrel is formed on the front surface of the camera body 10. The lens mount 12 has a circular shape, and is positioned directly below the optical device 30 when the camera body 10 is viewed from the front. The lens mount 12 is provided with a contact 13 for performing data communication between the control system in the camera body 10 and the control system in the lens barrel, a claw 14 for attaching the lens barrel, and the like.

図２はカメラ本体の中の構造の一部を抜き出して示すものである。レンズマウント１２は暗箱１５の前面に固定される。暗箱１５の上部には、発光装置３０が出没自在に取付けられる収納凹部１６が形成される。カメラ本体の背面側には撮像素子１７が設けられ、撮像素子１７と暗箱１５の間にはシャッタ１８が設けられる。撮像素子１７の前面に設けられる撮像領域１７ａはカバーガラス１９により覆われる。図３に示すように撮像領域１７ａは、カメラ本体を正面から見ると矩形を呈し、撮像素子１７はレンズマウント１２の中央部に受光面１９の中心が位置するようにして配置される。また収納凹部１６の幅はレンズマウント１２の幅よりも小さい。   FIG. 2 shows a part of the structure inside the camera body. The lens mount 12 is fixed to the front surface of the dark box 15. On the upper part of the dark box 15, a housing recess 16 is formed in which the light emitting device 30 can be freely inserted and retracted. An image sensor 17 is provided on the back side of the camera body, and a shutter 18 is provided between the image sensor 17 and the dark box 15. An imaging region 17 a provided on the front surface of the imaging element 17 is covered with a cover glass 19. As shown in FIG. 3, the imaging area 17 a has a rectangular shape when the camera body is viewed from the front, and the imaging element 17 is arranged so that the center of the light receiving surface 19 is located at the center of the lens mount 12. The width of the storage recess 16 is smaller than the width of the lens mount 12.

本実施形態において収納凹部１６はレンズマウント１２の上部に形成され、発光装置３０の上面３１がカメラ本体の上面から突出する量が極力小さくなるよう、できるだけ下方に位置するように考慮されている。すなわちレンズマウント１２の上端１２ａを基準として見た場合に、上端１２ａから収納凹部１６の内側底面２５までの高さは、上端１２ａから発光装置３０の上面３１までの高さよりも大きい。収納凹部１６の内側底面２５は、図２に示すようにレンズマウント１２の上側縁部２１に設けられた係合爪の下縁２１ａと撮像領域１７ａの上辺２２との間に位置し、また収納凹部１６の前端面２３はレンズマウント１２よりもカメラ本体の背面側に位置する。すなわち収納凹部１６および収納状態にある発光装置３０の全てがレンズマウント１２よりも背面側に位置する。   In the present embodiment, the storage recess 16 is formed in the upper part of the lens mount 12 and is considered to be positioned as low as possible so that the amount of the upper surface 31 of the light emitting device 30 protruding from the upper surface of the camera body is minimized. That is, when viewed from the upper end 12 a of the lens mount 12, the height from the upper end 12 a to the inner bottom surface 25 of the housing recess 16 is larger than the height from the upper end 12 a to the upper surface 31 of the light emitting device 30. The inner bottom surface 25 of the housing recess 16 is located between the lower edge 21a of the engaging claw provided on the upper edge 21 of the lens mount 12 and the upper side 22 of the imaging area 17a as shown in FIG. The front end surface 23 of the recess 16 is located on the back side of the camera body with respect to the lens mount 12. That is, all of the storage recess 16 and the light emitting device 30 in the storage state are located on the back side of the lens mount 12.

このように収納凹部１６は、下端部２０が撮影レンズからの入射光に干渉しない限度において最下位置に設けられており、これにより発光装置３０の上面３１はカメラ本体１０の上面に設けられた発光装置３０以外の部材（本実施形態ではモードダイアル１１）と略同じ高さにあり、この部材よりも大きく突出することはない。また撮像レンズの設計に応じて、収納凹部１６の下端部２０をさらに下方に定めることができ、下端部２０が撮像領域１７ａの上辺２２にできるだけ近づくように、収納凹部１６の内側底面２５を下方に位置させればよい。   As described above, the housing recess 16 is provided at the lowest position as long as the lower end 20 does not interfere with the incident light from the photographing lens, whereby the upper surface 31 of the light emitting device 30 is provided on the upper surface of the camera body 10. It is substantially the same height as a member other than the light emitting device 30 (mode dial 11 in this embodiment), and does not protrude larger than this member. Further, depending on the design of the imaging lens, the lower end 20 of the storage recess 16 can be further set downward, and the inner bottom surface 25 of the storage recess 16 is set downward so that the lower end 20 is as close as possible to the upper side 22 of the imaging region 17a. What is necessary is just to be located.

図２から理解されるように、収納状態にある発光装置３０の高さ、すなわち内側底面２５から上面３１までの高さは、暗箱１５の高さよりも小さく、発光装置３０はコンパクトに折り畳まれて収納凹部１６に収納される。   As understood from FIG. 2, the height of the light emitting device 30 in the housed state, that is, the height from the inner bottom surface 25 to the upper surface 31 is smaller than the height of the dark box 15, and the light emitting device 30 is compactly folded. It is stored in the storage recess 16.

図４は発光装置３０がポップアップした状態を示している。発光装置３０は第１のアーム３２と第２のアーム３３によってカメラ本体に回動自在に支持されており、これらのアーム３２、３３が図２の収納状態から立ち上がることによって発光ユニット３４がポップアップする。ポップアップ状態において、第１のアーム３２は収納凹部１６の底面に対して略垂直であり、第２のアーム３３は第１のアーム３２よりも撮像素子１７側に傾斜しており、発光ユニット３４の発光部３５の前面はレンズマウント１２の面に略平行である。   FIG. 4 shows a state where the light emitting device 30 pops up. The light emitting device 30 is rotatably supported on the camera body by a first arm 32 and a second arm 33, and the light emitting unit 34 pops up when these arms 32 and 33 are raised from the stored state of FIG. . In the pop-up state, the first arm 32 is substantially perpendicular to the bottom surface of the housing recess 16, the second arm 33 is inclined toward the image sensor 17 with respect to the first arm 32, and the light emitting unit 34 The front surface of the light emitting unit 35 is substantially parallel to the surface of the lens mount 12.

再び図２を参照すると、収納状態、すなわち第１および第２のアーム３２、３３と連結部材３６と発光ユニット３４を収納凹部１６に収納した状態において、第１および第２のアーム３２、３３と発光ユニット３４は相互に平行であり、発光部３５は、後述するピン４１に近接しており、また第１のアーム３２と発光ユニット３４を連結する連結部材３６は、アーム３２と３３と発光ユニット３４に対して略垂直である。すなわち発光装置３０は収納状態においてカメラ本体の横方向から見てコの字状を呈する。   Referring again to FIG. 2, the first and second arms 32 and 33 in the storage state, that is, in the state where the first and second arms 32 and 33, the connecting member 36 and the light emitting unit 34 are stored in the storage recess 16. The light emitting units 34 are parallel to each other, the light emitting unit 35 is close to a pin 41 to be described later, and the connecting member 36 that connects the first arm 32 and the light emitting unit 34 includes the arms 32 and 33 and the light emitting unit. 34 is substantially perpendicular. That is, the light emitting device 30 has a U shape when viewed from the side of the camera body in the housed state.

図５、６、７を参照して発光装置３０のカメラ本体に対する支持機構の構成を説明する。第１のアーム３２は第１支持部であるピン４１によってカメラ本体に枢支される。連結部材３６は第１のアーム３２の先端に、第２支持部であるピン４２によって回動自在に連結される。発光ユニット３４は連結部材３６において、ピン４２とは反対側の端部に位置する第３支持部のピン４３に回動自在に連結される。第２のアーム３３は第１支持部のピン４１とは異なる第４支持部であるピン４４によってカメラ本体に枢支される。第２アーム３３の先端は第３支持部のピン４３に連結される。このように、第１および第２のアーム３２、３３と連結部材３６とピン４１〜４４によってリンク機構が構成される。   The structure of the support mechanism for the camera body of the light emitting device 30 will be described with reference to FIGS. The first arm 32 is pivotally supported on the camera body by a pin 41 which is a first support portion. The connecting member 36 is rotatably connected to the tip of the first arm 32 by a pin 42 that is a second support portion. The light emitting unit 34 is rotatably connected to the pin 43 of the third support portion located at the end of the connecting member 36 opposite to the pin 42. The second arm 33 is pivotally supported on the camera body by a pin 44 which is a fourth support portion different from the pin 41 of the first support portion. The tip of the second arm 33 is connected to the pin 43 of the third support part. Thus, the first and second arms 32 and 33, the connecting member 36, and the pins 41 to 44 constitute a link mechanism.

発光ユニット３４の側壁５１には円弧状のスリット５２が形成される。第２のアーム３３のピン４３に近接した部位には係合ピン５３が固定され、係合ピン５３は円弧状スリット５２に係合する。発光ユニット３４は係合ピン５３が円弧状スリット５２に係合する範囲内において第２のアーム３３に対して回動自在である。すなわち係合ピン５３は、図２の収納状態では円弧状スリット５２の一方の端部に係止し、図４のポップアップ状態では円弧状スリット５２の他方の端部に係止する。   An arc-shaped slit 52 is formed in the side wall 51 of the light emitting unit 34. An engagement pin 53 is fixed to a portion of the second arm 33 adjacent to the pin 43, and the engagement pin 53 engages with the arc-shaped slit 52. The light emitting unit 34 is rotatable with respect to the second arm 33 within a range where the engaging pin 53 engages with the arc-shaped slit 52. That is, the engaging pin 53 is locked to one end of the arc-shaped slit 52 in the retracted state of FIG. 2, and is locked to the other end of the arc-shaped slit 52 in the pop-up state of FIG.

ピン４３にはコイルバネであるポップアップバネ５４が設けられる。バネ５４の一方の端部は発光ユニット３４に係止し、他方の端部は係合ピン５３すなわち第２のアーム３３に係止する（図８、１０参照）。バネ５４により、発光ユニット３４と第２のアーム３３は、これらの成す角が１８０度に近づく方向に常時付勢される。例えば図２に示す収納状態では、発光ユニット３４と第２のアーム３３の成す角は略０度であり、発光ユニット３４はピン４３を中心として第２のアーム３３から離れる方向に回動する方向に付勢される。また図４に示すポップアップ状態では、発光ユニット３４は第２のアーム３３と成す角がより大きくなる方向に付勢されるが、係合ピン５３が円弧状スリット５２の端部に係止するため、発光ユニット３４と第２のアーム３３の成す角はこれ以上大きくならない。   The pin 43 is provided with a pop-up spring 54 that is a coil spring. One end of the spring 54 is locked to the light emitting unit 34, and the other end is locked to the engaging pin 53, that is, the second arm 33 (see FIGS. 8 and 10). By means of the spring 54, the light emitting unit 34 and the second arm 33 are constantly urged in a direction in which the angle formed between them approaches 180 degrees. For example, in the storage state shown in FIG. 2, the angle formed between the light emitting unit 34 and the second arm 33 is approximately 0 degrees, and the light emitting unit 34 rotates in a direction away from the second arm 33 around the pin 43. Be energized by. In the pop-up state shown in FIG. 4, the light emitting unit 34 is urged in a direction in which the angle formed with the second arm 33 becomes larger, but the engaging pin 53 is locked to the end of the arc-shaped slit 52. The angle formed between the light emitting unit 34 and the second arm 33 does not increase any more.

カメラ本体の上面であって収納凹部１６の側方には、係止爪６１が設けられる。係止爪６１はカメラ本体１０の前後方向、すなわち第１および第２のアーム３２、３３が回動する面に平行な面に沿って変位自在であり、第１および第２のアーム３２、３３と連結部材３６と発光ユニット３４とを収納凹部１６に収納した状態（図２に示す収納状態）において発光ユニット３４に係合可能である。発光ユニット３４の下面には、係止爪６１が係合するための溝６２が形成される。   A locking claw 61 is provided on the upper surface of the camera body and on the side of the storage recess 16. The locking claw 61 is displaceable along the front-rear direction of the camera body 10, that is, along the plane parallel to the plane on which the first and second arms 32, 33 rotate, and the first and second arms 32, 33. The connecting member 36 and the light emitting unit 34 can be engaged with the light emitting unit 34 in a state where the connecting recess 36 is housed in the housing recess 16 (the housing state shown in FIG. 2). On the lower surface of the light emitting unit 34, a groove 62 for engaging the locking claw 61 is formed.

カメラ本体１０内には係止爪６１を変位させるための係止爪駆動部６３が配設される。係止爪駆動部６３は電磁石６４と可動部材６５と係止バネ６６とを有する。係止爪６１は、図示しない支点の周りに回動自在であり、可動部材６５は支点を挟んで係止爪６１とは反対側の揺動部に連結される。係止爪６１は係止バネ６６によってカメラ本体１０の前方（図７の右方）に付勢される。可動部材６５は電磁石６４が通電されたとき、図７の右方に突出し、この突出動作に連動して係止バネ６６の付勢力により係止爪６１が図７の左方に後退する。すなわち図２に示す収納状態では、係止爪６１は溝６２に係合し、これにより発光ユニット３４は収納状態に保持されるが、発光ボタン３９が押されて電磁石６４が通電されると、係止爪６１が後退して溝６２を解放し、発光ユニット３４がポップアップする。   A locking claw driving unit 63 for displacing the locking claw 61 is disposed in the camera body 10. The locking claw driving unit 63 includes an electromagnet 64, a movable member 65, and a locking spring 66. The locking claw 61 is rotatable around a fulcrum (not shown), and the movable member 65 is connected to a swinging portion on the opposite side of the locking claw 61 with the fulcrum interposed therebetween. The locking claw 61 is urged forward (rightward in FIG. 7) of the camera body 10 by a locking spring 66. When the electromagnet 64 is energized, the movable member 65 protrudes to the right in FIG. 7, and the interlocking claw 61 is retracted to the left in FIG. That is, in the storage state shown in FIG. 2, the locking claw 61 engages with the groove 62, whereby the light emitting unit 34 is held in the storage state, but when the light emitting button 39 is pressed and the electromagnet 64 is energized, The locking claw 61 moves backward to release the groove 62, and the light emitting unit 34 pops up.

図６から理解されるように、カメラ本体を前面側から見たときに、第１のアーム３２と連結部材３６と係止爪駆動部６３とが発光部３５の幅の中に収まるように構成されている。第１のアーム３２と連結部材３６の中はそれぞれ、発光ユニット３４と図示しない電子回路を電気的に接続するリード線が収納されており、第１のアーム３２と連結部材３６のピン４１の軸方向に沿う長さは発光部３５の幅よりも小さく、第１のアーム３２と第２のアーム３３との間に形成されるスペースに、係止爪駆動部６３と係止爪６１が配置されている。   As can be understood from FIG. 6, the first arm 32, the connecting member 36, and the locking claw drive unit 63 are configured to fit within the width of the light emitting unit 35 when the camera body is viewed from the front side. Has been. Each of the first arm 32 and the connecting member 36 accommodates a lead wire for electrically connecting the light emitting unit 34 and an electronic circuit (not shown), and the shaft of the pin 41 of the first arm 32 and the connecting member 36 is accommodated. The length along the direction is smaller than the width of the light emitting portion 35, and the locking claw driving portion 63 and the locking claw 61 are disposed in the space formed between the first arm 32 and the second arm 33. ing.

図８〜１１を参照して、本実施形態において採用されているポップアップ機構の構成と作用を説明する。
連結部材３６を貫通して延びる第３支持部のピン４３には、上述したようにポップアップバネ５４が設けられる。また連結部材３６には、円板の一部を径方向の外側に膨出させて形成されたストッパ７１が形成される。ストッパ７１は発光ユニット３４に形成された当接面７２に当接可能である。一方第２のアーム３３は、ピン４４の近傍において第３支持部のピン４３とは反対方向に延びる突起７３を有する。この突起７３はカメラ本体に固定されたストッパピン７４に係合可能である。 With reference to FIGS. 8-11, the structure and effect | action of the pop-up mechanism employ | adopted in this embodiment are demonstrated.
As described above, the pop-up spring 54 is provided on the pin 43 of the third support portion that extends through the connecting member 36. Further, the connecting member 36 is formed with a stopper 71 formed by bulging a part of the disk outward in the radial direction. The stopper 71 can come into contact with a contact surface 72 formed on the light emitting unit 34. On the other hand, the second arm 33 has a protrusion 73 extending in the direction opposite to the pin 43 of the third support portion in the vicinity of the pin 44. The protrusion 73 can be engaged with a stopper pin 74 fixed to the camera body.

発光装置の収納状態では、図８、９に示すように、発光ユニット３４と第２のアーム３３の成す角は略０度である。また発光ユニット３４は連結部材３６に対して略垂直であり、ストッパ７１は当接面７２から離間している。この状態において係止爪６１が後退して発光ユニット３４を解放すると、バネ５４の付勢力により、発光ユニット３４は連結部材３６に対して回動するように作用し、図１０、１１に示すように発光ユニット３４は連結部材３６に対して起き上がる。発光ユニット３４の当接面７２にストッパ７１が当接すると、発光ユニット３４は連結部材３６に対して回動しなくなり、発光ユニット３４と第２のアーム３３はバネ５４の付勢力により、これらの成す角が大きくなるように変化する。すなわち、図１２に示すように第２のアーム３３がピン４４を中心に回動して起き上がり、突起７３がストッパピン７４に係合した位置において静止する。   In the housed state of the light emitting device, as shown in FIGS. 8 and 9, the angle formed by the light emitting unit 34 and the second arm 33 is approximately 0 degrees. The light emitting unit 34 is substantially perpendicular to the connecting member 36, and the stopper 71 is separated from the contact surface 72. In this state, when the locking claw 61 moves backward to release the light emitting unit 34, the light emitting unit 34 is rotated with respect to the connecting member 36 by the urging force of the spring 54, as shown in FIGS. Further, the light emitting unit 34 rises with respect to the connecting member 36. When the stopper 71 comes into contact with the contact surface 72 of the light emitting unit 34, the light emitting unit 34 stops rotating with respect to the connecting member 36, and the light emitting unit 34 and the second arm 33 are moved by the biasing force of the spring 54. It changes so that the formed angle becomes large. That is, as shown in FIG. 12, the second arm 33 rises by rotating around the pin 44, and stops at a position where the protrusion 73 is engaged with the stopper pin 74.

以上のように本実施形態の発光装置３０の支持機構は、第１のアーム３２に連結部材３６を介して発光ユニット３４を連結したので、発光ユニット３４のポップアップ高さが十分に大きくなり、したがって、カメラ本体１０に装着された撮影レンズの突出量が大きくてもケラレが発生することが防止される。   As described above, since the support mechanism of the light emitting device 30 of the present embodiment connects the light emitting unit 34 to the first arm 32 via the connecting member 36, the pop-up height of the light emitting unit 34 becomes sufficiently large. The occurrence of vignetting is prevented even if the projection amount of the photographic lens mounted on the camera body 10 is large.

また、発光ユニット３４が収納状態にあるとき、発光装置３０は全体的にコの字状になるように折り畳まれるので、収納凹部１６内にコンパクトに収納される。さらに、収納凹部１６の内側底面２５はレンズマウント１２の上側縁部２１と撮像素子１７の受光面１９の上辺２２との間に位置し、また収納凹部１６の前端面２３がレンズマウント１２よりもカメラ本体の背面側に位置している。したがって、収納凹部１６を極力下方に配置することができ、発光装置３０の上面３１のカメラ本体１０の上面からの突出量を小さく抑えることができる。   Further, when the light emitting unit 34 is in the housed state, the light emitting device 30 is folded so as to be entirely U-shaped, so that it is housed in the housing recess 16 in a compact manner. Further, the inner bottom surface 25 of the housing recess 16 is located between the upper edge 21 of the lens mount 12 and the upper side 22 of the light receiving surface 19 of the image sensor 17, and the front end surface 23 of the housing recess 16 is more than the lens mount 12. Located on the back side of the camera body. Therefore, the storage recess 16 can be disposed as low as possible, and the amount of protrusion of the upper surface 31 of the light emitting device 30 from the upper surface of the camera body 10 can be kept small.

なお、上記実施形態では、ポップアップバネ５４はピン４３のみに設けられていたが、これに代えて、バネを、ピン４１、４２に設けるとともに、発光ユニット３４と連結部材３６の間に設けてもよく、このような構成によると第２のアーム３３を省略することができる。   In the above embodiment, the pop-up spring 54 is provided only on the pin 43, but instead of this, a spring may be provided on the pins 41 and 42 and provided between the light emitting unit 34 and the connecting member 36. Well, according to such a configuration, the second arm 33 can be omitted.

なお発光ユニット３４は電磁石６４を設けるのではなく、発光ボタン３９を押すと機械的に係止爪６１が外れるように構成されてもよい。   The light emitting unit 34 may be configured not to provide the electromagnet 64 but to mechanically disengage the locking claw 61 when the light emitting button 39 is pressed.
