Description

ストロボ装置Strobe device
 本発明は、被写体などの照射対象に向けて閃光を発する光源などを備えたストロボ装置に関する。詳しくは、照射対象に対する閃光の照射角を可変としたストロボ装置に関する。 The present invention relates to a strobe device provided with a light source or the like that emits a flash toward an irradiation target such as a subject. More specifically, the present invention relates to a strobe device in which the irradiation angle of the flash light to the irradiation object is variable.
 ストロボ装置は、一般的に、閃光を発するキセノン(Xe)放電管のような棒状の光源と、光源から発せられた閃光を被写体などの照射対象に向けて反射させる樋状の反射傘とを備えている。また、ズーム機能を備えたカメラ用のストロボ装置は、照射対象に対する閃光の照射角を変更できる構成を、さらに備えている(例えば、特許文献1および特許文献2参照)。 A strobe device generally includes a rod-like light source such as a xenon (Xe) discharge tube that emits flash light, and a bowl-shaped reflector that reflects the flash light emitted from the light source toward an irradiation target such as a subject. ing. In addition, a flash device for a camera having a zoom function is further provided with a configuration capable of changing the irradiation angle of the flash light to the irradiation object (see, for example, Patent Document 1 and Patent Document 2).
 具体的には、特許文献1に記載されたストロボ装置は、反射傘の両端から前方に向けられた一対の側方反射板と、光源を反射傘内で光軸方向に移動させる駆動部とを、備えている。上記ストロボ装置は、望遠撮影を行うテレ側において、光源を反射傘の底側に近づける。同時に、一対の側方反射板の開口角度を広くする。これにより、ストロボ装置の光源から発する、照射対象に対する閃光の照射角を小さくしている。一方、広角撮影を行うワイド時においては、光源を反射傘の開口側の位置に移動させる。同時に、一対の側方反射板の開口角度を狭くする。これにより、ストロボ装置の光源から発する、照射対象に対する閃光の照射角を大きくしている。 Specifically, the strobe device described in Patent Document 1 includes a pair of side reflectors directed forward from both ends of the reflector and a drive unit for moving the light source in the reflector in the optical axis direction. , Equipped. The strobe device brings the light source closer to the bottom side of the reflector on the tele side where the telephoto shooting is performed. At the same time, the opening angle of the pair of side reflectors is increased. Thereby, the irradiation angle of the flashlight to the irradiation object emitted from the light source of the strobe device is reduced. On the other hand, when wide-angle shooting is performed, the light source is moved to the position on the opening side of the reflector. At the same time, the opening angle of the pair of side reflectors is narrowed. Thereby, the irradiation angle of the flash light with respect to the irradiation object emitted from the light source of the strobe device is increased.
 また、特許文献2に記載されたストロボ装置は、光源を保持する光源保持部材と、光源保持部材に保持された光源を反射傘内で往復動させるウォームギヤとを、備えている。上記ストロボ装置は、光源を反射傘の開口側に移動させて、照射角を大きくすることにより、広角レンズの画角に適する照射状態を実現している。一方、光源を反射傘の奥側に移動させて、照射角を小さくすることにより、望遠レンズの画角に適する照射状態を実現している。 Further, the strobe device described in Patent Document 2 includes a light source holding member for holding a light source, and a worm gear for reciprocating the light source held by the light source holding member in the reflector. The strobe device realizes an illumination state suitable for the angle of view of the wide-angle lens by moving the light source to the opening side of the reflector and enlarging the illumination angle. On the other hand, by moving the light source to the back side of the reflector and reducing the irradiation angle, the irradiation state suitable for the angle of view of the telephoto lens is realized.
 つまり、特許文献1のストロボ装置は、まず、一対の側方反射板の開口角度を変更する。そして、光源を反射傘内で移動させて照射角を変更するだけである。そのため、光源および反射傘を一体的に光軸方向に移動させる構成ではない。 That is, the strobe device of Patent Document 1 first changes the opening angles of the pair of side reflectors. Then, only the light source is moved within the reflector to change the irradiation angle. Therefore, the light source and the reflector are not integrally moved in the optical axis direction.
 また、特許文献2のストロボ装置は、一対の側方反射板を備えていない。 Further, the strobe device of Patent Document 2 does not include a pair of side reflectors.
 したがって、上記いずれのストロボ装置も、例えば「光源および反射傘を一体的に移動できない」、「側方反射板が固定」などの光学設計条件が限定されるという課題がある。 Therefore, in any of the above-described strobe devices, there is a problem that optical design conditions such as "the light source and the reflector can not be moved integrally", "the side reflector is fixed", etc. are limited.
 さらに、特許文献2のストロボ装置は、光源を光軸方向に移動させるウォームギヤを、反射傘の奥側から光軸方向に突出するように配備している。そのため、ストロボ装置が大型化し、近年、要望されるストロボ装置の小型化を実現できないという課題があった。 Further, in the strobe device of Patent Document 2, a worm gear for moving the light source in the optical axis direction is disposed so as to protrude from the back side of the reflector in the optical axis direction. Therefore, there has been a problem that the size of the strobe device is increased, and in recent years, the miniaturization of the desired strobe device can not be realized.

 本発明は、光学設計条件を限定することなく、小型化が図れるとともに、光源から発せられた閃光の照射角を可変にできるストロボ装置を提供する。 SUMMARY OF THE INVENTION The present invention provides a strobe device that can be miniaturized and can change the irradiation angle of flash light emitted from a light source without limiting the optical design conditions.
 つまり、本発明のストロボ装置は、閃光を発する光源と、光源から発せられた閃光を照射対象に向けて反射させる反射部とを備える発光部と、光源で発した閃光を透過させる閃光透過部を有し、閃光透過部に光源を向き合わせるように発光部を収納するケーシングと、発光部をケーシング内で閃光透過部に接離する方向に往復動させる駆動部とを備える。発光部の反射部は、閃光透過部に向けられた反射傘と、照射対象に向ける閃光の照射角を変更できるように反射傘に隣り合って揺動可能に配置された一対の側方反射板とを備える。そして、一対の側方反射板は、発光部の往復動に連動して揺動することにより、開口角度を変更可能な構成を有している。 That is, the strobe device of the present invention comprises: a light emitting unit including a light source emitting a flash light, a reflecting section reflecting the flash light emitted from the light source toward the irradiation target, and a flash light transmitting section transmitting the flash light emitted by the light source It has a casing which accommodates a light emission part so that a light source may be made to face a flash light transmission part, and a drive part which makes a light emission part reciprocate in the direction which contacts and separates a flash light transmission part within a casing. The reflecting portion of the light emitting portion is a reflector directed to the flash light transmitting portion, and a pair of side reflecting plates arranged swingably adjacent to the reflector so as to be able to change the irradiation angle of the flash light directed to the irradiation object And The pair of side reflectors has a configuration in which the opening angle can be changed by swinging in conjunction with the reciprocation of the light emitting unit.
 この構成によれば、光源から発せられた閃光は、反射部、すなわち、反射傘と一対の側方反射板とで反射する。そして、反射部で反射した閃光は、ケーシングの閃光透過部を透過して照射対象を照射する。このとき、反射部を構成する一対の側方反射板は、ケーシング内で、発光部の往復動に連動して揺動する、これにより、一対の側方反射板の開口角度が変更される。その結果、照射対象に向けて反射する閃光の照射角を変更することができる。 According to this configuration, the flashlight emitted from the light source is reflected by the reflective portion, that is, the reflector and the pair of side reflectors. And the flash light reflected by the reflection part permeate | transmits the flash light transmission part of a casing, and irradiates irradiation object. At this time, the pair of side reflection plates constituting the reflection portion is rocked in conjunction with the reciprocating movement of the light emitting portion in the casing, whereby the opening angles of the pair of side reflection plates are changed. As a result, it is possible to change the irradiation angle of the flashlight reflected toward the irradiation target.
 具体的には、発光部がケーシングの背面側(閃光透過部と反対側)に位置している場合、発光部の移動に連動して一対の側方反射板が揺動し、一対の側方反射板の開口角度が広くなる。これにより、光源から発した閃光は、望遠撮影に適した狭い照射角で照射できる開口角度となった一対の側方反射板で反射する。一方、発光部がケーシングの閃光透過部側に位置している場合、発光部の移動に連動して一対の側方反射板が揺動し、一対の側方反射板の開口角度が狭くなる。これにより、光源から発した閃光は、広角撮影に適した狭い照射角で照射できる開口角度となった一対の側方反射板で反射する。 Specifically, when the light emitting unit is located on the back side of the casing (the opposite side to the flash light transmitting unit), the pair of side reflection plates swings in conjunction with the movement of the light emitting unit, and the pair of side reflectors The aperture angle of the reflecting plate is broadened. As a result, the flashlight emitted from the light source is reflected by the pair of side reflection plates having an opening angle that can be emitted at a narrow irradiation angle suitable for telephoto photography. On the other hand, when the light emitting portion is located on the side of the flashlight transmitting portion of the casing, the pair of side reflectors swings in conjunction with the movement of the light emitting portion, and the opening angle of the pair of side reflectors narrows. As a result, the flashlight emitted from the light source is reflected by the pair of side reflection plates having an opening angle that can be emitted at a narrow irradiation angle suitable for wide-angle shooting.
 その結果、光学設計条件を限定することなく、小型化が図れるとともに、光源から発せられた閃光の照射角を可変にできるストロボ装置を実現できる。 As a result, without limiting the optical design conditions, miniaturization can be achieved, and a strobe device can be realized in which the irradiation angle of the flash light emitted from the light source can be made variable.

 そして、フレーム14の一対のフレーム軸受部145は、ホルダー12の一対のホルダー軸受部124を挟み込んで配置して形成される。さらに、ヒンジ用フレーム軸孔とヒンジ用軸孔124aとに、ヒンジ用軸部材15を挿通する。これにより、ホルダー12とフレーム14が連続する状態で一体化される。その結果、ホルダー12は、ヒンジ用軸部材15を揺動軸として、Z方向に対して、仰向きの状態と俯きの状態とに傾動可能に構成される。この場合、図5や図8に示すように、ヒンジ用軸部材15には、例えばトーションバネなどの付勢部材19が取り付けられる。これにより、ホルダー12は、図5に示すように、定常状態において、仰向きの状態になるように保持される。 The pair of frame bearing portions 145 of the frame 14 is formed by sandwiching the pair of holder bearing portions 124 of the holder 12. Furthermore, the hinge shaft member 15 is inserted into the hinge frame shaft hole and the hinge shaft hole 124a. Thereby, the holder 12 and the frame 14 are integrated in a continuous state. As a result, the holder 12 is configured to be tiltable in the state of supposing and in the state of turning in the Z direction with the hinge shaft member 15 as a swing axis. In this case, as shown in FIGS. 5 and 8, a biasing member 19 such as a torsion spring is attached to the hinge shaft member 15. Thereby, the holder 12 is held in the supine state in the steady state as shown in FIG.
 さらに、フレーム14の枠体部142の正面側には、光源10から発せられた閃光を透過させる、例えばフレネルレンズなどのカバー16が取り付けられている。 Furthermore, on the front side of the frame portion 142 of the frame 14, a cover 16 such as a Fresnel lens for transmitting flash light emitted from the light source 10 is attached.
 また、フレーム14の枠体部142のX方向の両端部は、基部141のX方向の両端よりも突出するように設けられている。これにより、フレーム14の枠体部142の端部と基部141の端部とが隣接する部位に、空間部が形成される。形成された空間部に、ホルダー12の光源保持部122が配置して設けられる。さらに、形成された空間部に、フレーム14の支軸部143が、Z方向に突出した状態で配置される。なお、フレーム14の支軸部143には、ネジ孔(図示せず)が、Z方向に形成されている。 Further, both end portions in the X direction of the frame body portion 142 of the frame 14 are provided so as to project more than both ends in the X direction of the base portion 141. Thereby, a space part is formed in the part which the end of frame body part 142 of frame 14 and the end of base 141 adjoin. The light source holding portion 122 of the holder 12 is disposed and provided in the formed space portion. Furthermore, the support shaft portion 143 of the frame 14 is disposed in the formed space portion so as to protrude in the Z direction. A screw hole (not shown) is formed in the Z direction in the support shaft portion 143 of the frame 14.
 また、反射部11を構成する一対の側方反射板112は、図3や図4に示すように、例えば板状の反射部材112aと、反射板保持部112bと、当接部112cとを備えている。反射部材112aは、フレーム14の枠体部142の両方の端部の内側に配置される。反射板保持部112bは、反射部材112aのZ方向の両端に設けられている。当接部112cは、反射部材112aのY方向の背面側端縁に設けられている。反射板保持部112bには、小孔(図示せず)がZ方向に形成されている。 Further, as shown in FIG. 3 and FIG. 4, the pair of side reflection plates 112 constituting the reflection portion 11 includes, for example, a plate-like reflection member 112 a, a reflection plate holding portion 112 b, and an abutment portion 112 c. ing. The reflecting member 112 a is disposed inside both ends of the frame portion 142 of the frame 14. The reflection plate holding portions 112 b are provided at both ends of the reflection member 112 a in the Z direction. The contact portion 112 c is provided at the rear edge of the reflection member 112 a in the Y direction. Small holes (not shown) are formed in the Z direction in the reflection plate holding portion 112b.
 これにより、一対の側方反射板112の反射板保持部112bを、フレーム14の支軸部143に重ね合わすことができる。このとき、重ね合わされた状態において、反射板保持部112bの小孔とフレーム14の支軸部143に形成されたネジ孔とが連通する。そして、反射板保持部112bの小孔からフレーム14の支軸部143のネジ孔にネジ部材17を通す。これにより、ネジ部材17を回転軸として、フレーム14に対して、一対の側方反射板112が左右(X方向)に揺動可能に一体化される。その結果、一対の側方反射板112のX方向の開口角度を、任意に変更することができる。 Thereby, the reflection plate holding portions 112 b of the pair of side reflection plates 112 can be superimposed on the support shaft portions 143 of the frame 14. At this time, the small holes of the reflection plate holding portion 112 b communicate with the screw holes formed in the support shaft portion 143 of the frame 14 in the overlapped state. Then, the screw member 17 is passed through the small hole of the reflection plate holding portion 112 b and the screw hole of the support shaft portion 143 of the frame 14. As a result, with the screw member 17 as a rotation axis, the pair of side reflection plates 112 is integrated with the frame 14 so as to be swingable to the left and right (X direction). As a result, the opening angle in the X direction of the pair of side reflectors 112 can be arbitrarily changed.
 また、反射板保持部112bには、反射部材112aと反対方向に引掛け部(図示せず)が突出して設けられている。同様に、フレーム14のガイド部144にも、引掛け部(図示せず)が突出して設けられている。そして、図3に示すように、反射部材112aの引掛け部とガイド部144の引掛け部には、例えば引張バネなどの弾性部材18が架け渡されている。これにより、一対の側方反射板112は、図4に示すように、定常状態において、X方向に開いた状態で保持される。つまり、定常状態において、一対の側方反射板112は、X方向に対して、開口角度が広く開いた状態で保持される。 Further, a hooking portion (not shown) is provided in the reflecting plate holding portion 112b so as to protrude in the opposite direction to the reflecting member 112a. Similarly, a hooking portion (not shown) is provided in the guide portion 144 of the frame 14 so as to project therefrom. Then, as shown in FIG. 3, an elastic member 18 such as a tension spring is bridged between the hooking portion of the reflecting member 112 a and the hooking portion of the guide portion 144. As a result, as shown in FIG. 4, the pair of side reflectors 112 are held in the open state in the X direction in the steady state. That is, in the steady state, the pair of side reflection plates 112 is held in a state where the opening angle is wide open with respect to the X direction.
 また、図1や図2に示すように、ケーシング2は、一対の側板部21と、底板部22と、天板部23と、背面部24とから構成されている。底板部22は、一対の側板部21の一方の端縁(Z方向の下縁)に架け渡された状態で設けられている。天板部23は、一対の側板部21の他方の端縁(Z方向の上縁)に掛け渡された状態で設けられている、背面部24は、一対の側板部21、底板部22および天板部23で形成された背面側を部分的に塞ぐように設けられている。そして、ケーシング2の正面側は、開口した閃光透過部25で構成され、光源10から発せられた閃光がケーシング2の閃光透過部25を透過する。 Further, as shown in FIG. 1 and FIG. 2, the casing 2 is configured of a pair of side plate portions 21, a bottom plate portion 22, a top plate portion 23, and a back surface portion 24. The bottom plate portion 22 is provided in a state of being bridged to one end edge (lower edge in the Z direction) of the pair of side plate portions 21. The top plate portion 23 is provided in a state of being stretched over the other end edge (upper edge in the Z direction) of the pair of side plate portions 21. The back surface portion 24 includes the pair of side plate portions 21, the bottom plate portion 22 and It is provided so as to partially close the back side formed by the top plate portion 23. The front side of the casing 2 is constituted by the flash light transmitting portion 25 opened, and the flash light emitted from the light source 10 is transmitted through the flash light transmitting portion 25 of the casing 2.
 さらに、ケーシング2の天板部23のX方向の中心線近傍の部位には、駆動部3をセットする窓穴部23aが設けられている。そして、上記構成を有するケーシング2内に、背面側の位置と正面側の位置との間を往復動できるように、発光部1が収納されている。 Furthermore, a window hole 23a for setting the drive unit 3 is provided in a portion near the center line of the top plate 23 of the casing 2 in the X direction. The light emitting unit 1 is accommodated in the casing 2 having the above configuration so as to be able to reciprocate between the position on the back side and the position on the front side.
 また、図2や図5に示すように、ケーシング2の底板部22のX方向の中心で、背面側には、ホルダー12の従動部123が接触するカム面221が形成されている。底板部22に形成されたカム面221は、底板部22の背面側で窪んだ凹部221aと、底板部22の中心部で天板部23の方へ僅かに、例えば傾斜して膨らんだ凸部221bとが連続して、例えば直動カムのような形状で形成されている。 Further, as shown in FIG. 2 and FIG. 5, at the center of the bottom plate portion 22 of the casing 2 in the X direction, a cam surface 221 with which the driven portion 123 of the holder 12 contacts is formed on the back side. The cam surface 221 formed on the bottom plate portion 22 is a concave portion 221a recessed on the back side of the bottom plate portion 22 and a convex portion slightly bulging toward the top plate portion 23 at the central portion of the bottom plate portion 22, for example. 221 b are formed continuously, for example, in the shape of a linear motion cam.
 これにより、図5に示すように、発光部1が背面側に位置している場合、ホルダー12の従動部123は、カム面221の凹部221aの底面に接触する。その結果、ホルダー12は、付勢部材19の付勢力により、仰向き姿勢に維持される。一方、図8に示すように、発光部1が正面側(照射対象側)に位置に移動した場合、ホルダー12の従動部123は、カム面221の凸部221bに接触し、ホルダー12の下方の移動が止められる。このとき、ホルダー12の上方部分は、付勢部材19の付勢力に抗って、前方に回動しながら移動する。その結果、ホルダー12は、前方に俯き姿勢となる。 Thereby, as shown in FIG. 5, when the light emitting unit 1 is positioned on the back side, the driven unit 123 of the holder 12 contacts the bottom surface of the recess 221 a of the cam surface 221. As a result, the holder 12 is maintained in the supposing position by the biasing force of the biasing member 19. On the other hand, as shown in FIG. 8, when the light emitting unit 1 moves to the front side (irradiation target side), the driven unit 123 of the holder 12 contacts the convex portion 221 b of the cam surface 221 and the lower side of the holder 12 Movement is stopped. At this time, the upper portion of the holder 12 is moved forward while being against the biasing force of the biasing member 19. As a result, the holder 12 turns to the front.
 また、ケーシング2の天板部23には、図3に示す一対のガイド軸部材26がY方向に取り付けられている。一対のガイド軸部材26は、フレーム14のガイド部144に形成されたガイド部軸孔144aに挿通される。これにより、フレーム14を含む発光部1は、一対のガイド軸部材26に規制されながら、以下で説明する駆動部3によってY方向に往復動することができる。 Further, a pair of guide shaft members 26 shown in FIG. 3 is attached to the top plate portion 23 of the casing 2 in the Y direction. The pair of guide shaft members 26 are inserted into guide portion shaft holes 144 a formed in the guide portions 144 of the frame 14. Thus, the light emitting unit 1 including the frame 14 can be reciprocated in the Y direction by the driving unit 3 described below while being restricted by the pair of guide shaft members 26.
 また、図1から図3に示すように、駆動部3は、モータ31と、送りネジ32と、連結部材33などから構成されている。モータ31は、ケーシング2の天板部23に固定されている。送りネジ32は、モータ31のY方向に延出する回転軸に連結される。連結部材33は、送りネジ32の周方向の回転によって、Y方向に往復動する。このとき、連結部材33は、フレーム14の基部141に連結されている。そのため、連結部材33のY方向の往復動にともなって、フレーム14の基部141は、Y方向に往復動する。 Further, as shown in FIGS. 1 to 3, the drive unit 3 is configured of a motor 31, a feed screw 32, a connecting member 33 and the like. The motor 31 is fixed to the top plate portion 23 of the casing 2. The feed screw 32 is connected to a rotating shaft extending in the Y direction of the motor 31. The coupling member 33 reciprocates in the Y direction by rotation of the feed screw 32 in the circumferential direction. At this time, the connecting member 33 is connected to the base 141 of the frame 14. Therefore, with the reciprocation of the connecting member 33 in the Y direction, the base 141 of the frame 14 reciprocates in the Y direction.
 つまり、駆動部3のモータ31の回転により、送りネジ32が周方向に回転する。これにより、駆動部3の連結部材33が、送りネジ32に沿ってY方向に移動する。その結果、連結部材33に連結されたフレーム14を含む発光部1が、Y方向に移動する。なお、モータ31や送りネジ32は、天板部23の窓穴部23aに収納された状態で配置し、天板部23から突出しない状態で配置することが好ましい。これにより、ストロボ装置の小型化を図ることができる。 That is, due to the rotation of the motor 31 of the drive unit 3, the feed screw 32 rotates in the circumferential direction. Thereby, the connecting member 33 of the drive unit 3 moves in the Y direction along the feed screw 32. As a result, the light emitting unit 1 including the frame 14 connected to the connecting member 33 moves in the Y direction. It is preferable that the motor 31 and the feed screw 32 be disposed in the state of being stored in the window hole portion 23 a of the top plate portion 23 and be disposed so as not to protrude from the top plate portion 23. As a result, the flash device can be miniaturized.
 以上のように、本実施の形態のストロボ装置が、構成されている。 As described above, the strobe device of the present embodiment is configured.
 以下に、本実施の形態のストロボ装置の使用態様について説明する。 The usage of the strobe device according to the present embodiment will be described below.
 まず、発光部1が、図1、図2、図4および図5に示すように、ケーシング2の背面側に位置している場合について、説明する。 First, the case where the light emitting unit 1 is located on the back side of the casing 2 as shown in FIGS. 1, 2, 4 and 5 will be described.
 この状態の場合、ホルダー12の従動部123は、ケーシング2のカム面221の凹部221a内の位置にある。このとき、ホルダー12は、トーションバネなどの付勢部材19によって、仰向きの姿勢になっている。つまり、ホルダー12の押圧部125は、一対の側方反射板112の当接部112cから離れた位置にある。 In this state, the driven portion 123 of the holder 12 is at a position in the recess 221 a of the cam surface 221 of the casing 2. At this time, the holder 12 is in the supposing position by the biasing member 19 such as a torsion spring. That is, the pressing portion 125 of the holder 12 is located at a distance from the contact portion 112 c of the pair of side reflection plates 112.
 そのため、反射部11を構成する一対の側方反射板112は、図4に示すように、弾性部材18によって開いた状態、すなわち、X方向において開口角度が大きい状態で維持されている。これにより、発光部1の光源10から発せられた閃光は、望遠撮影に適した狭い照射角で照射対象を照明することができる。 Therefore, as shown in FIG. 4, the pair of side reflection plates 112 constituting the reflection portion 11 is maintained in an open state by the elastic member 18, that is, in a state in which the opening angle is large in the X direction. Thereby, the flashlight emitted from the light source 10 of the light emitting unit 1 can illuminate the illumination target at a narrow illumination angle suitable for telephoto shooting.
 つぎに、発光部1が、図6から図8に示すように、ケーシング2の閃光透過部25側に位置している場合について、説明する。 Next, a case where the light emitting unit 1 is positioned on the side of the flashlight transmitting unit 25 of the casing 2 as shown in FIGS. 6 to 8 will be described.
 具体的には、駆動部3のモータ31を作動させることにより、発光部1は、ケーシング2の正面側、すなわちケーシング2の閃光透過部25の方へ移動する。 Specifically, by operating the motor 31 of the drive unit 3, the light emitting unit 1 is moved to the front side of the casing 2, that is, toward the flash light transmitting unit 25 of the casing 2.
 そして、発光部1の移動途中において、ホルダー12の従動部123は、ケーシング2のカム面221の凸部221bに接触し、ホルダー12の従動部123側の移動が止められる。 Then, in the middle of the movement of the light emitting unit 1, the driven portion 123 of the holder 12 contacts the convex portion 221 b of the cam surface 221 of the casing 2 and the movement of the holder 12 on the driven portion 123 side is stopped.
 さらに、発光部1がケーシング2の閃光透過部25まで移動すると、ホルダー12は、付勢部材19の付勢力に抗し、ヒンジ用軸部材15を軸にして俯きの姿勢となるように回動する。そして、ホルダー12の押圧部125は、一対の側方反射板112の当接部112cに当接し、当接部112cを正面側に押す。これにより、反射部11の一対の側方反射板112は、図7に示すように、弾性部材18に抗して、閉じた状態、すなわち、X方向において、開口角度が狭くなる。その結果、発光部1の光源10から発せられた閃光は、広角撮影に適した広い照射角で照射対象を照明することができる。 Furthermore, when the light emitting portion 1 moves to the flashlight transmitting portion 25 of the casing 2, the holder 12 resists the biasing force of the biasing member 19 and pivots so as to assume a winding posture with the hinge shaft member 15 as an axis. Do. Then, the pressing portion 125 of the holder 12 abuts on the abutting portion 112 c of the pair of side reflection plates 112 and pushes the abutting portion 112 c to the front side. As a result, as shown in FIG. 7, the pair of side reflection plates 112 of the reflection unit 11 has a narrow opening angle in the closed state, that is, in the X direction against the elastic member 18. As a result, the flashlight emitted from the light source 10 of the light emitting unit 1 can illuminate the irradiation target at a wide irradiation angle suitable for wide-angle shooting.
 つぎに、駆動部3のモータ31を逆転させて、発光部1をケーシング2の背面側の位置に戻す。この場合、上記で説明したように、ホルダー12の従動部123は、ケーシング2のカム面221の凹部221a内の位置に戻る。これにより、ホルダー12は、付勢部材19の付勢力により、仰向きの姿勢に戻る。そして、ホルダー12の押圧部125は、一対の側方反射板112の当接部112cから離れ、当接が解除される。これにより、反射部11の一対の側方反射板112は、弾性部材18によって開いた状態に戻る。なお、上記では、発光部1が、完全にケーシング2の背面側と正面側に移動した例で説明したが、これに限られない。例えば、発光部1を、ケーシング2の背面側と正面側との中間の位置で停止させてもよい。これにより、望遠撮影から広角撮影において、任意の照射角で、照射対象を照明して撮影することができる。 Next, the motor 31 of the drive unit 3 is reversely rotated to return the light emitting unit 1 to the position on the back side of the casing 2. In this case, as described above, the driven portion 123 of the holder 12 returns to the position within the recess 221 a of the cam surface 221 of the casing 2. Thereby, the holder 12 returns to the posture of the supine position by the biasing force of the biasing member 19. And the press part 125 of the holder 12 leaves | separates from the contact part 112c of a pair of side reflection plate 112, and contact is cancelled | released. Thereby, the pair of side reflection plates 112 of the reflection portion 11 return to the open state by the elastic member 18. In addition, although the example which the light emission part 1 moved completely to the back side and front side of the casing 2 was demonstrated above, it is not restricted to this. For example, the light emitting unit 1 may be stopped at an intermediate position between the back side and the front side of the casing 2. As a result, it is possible to illuminate and shoot an irradiation target at an arbitrary irradiation angle in telephoto shooting and wide-angle shooting.
 以上のように、本実施の形態のストロボ装置によれば、発光部1をケーシング2内でY方向に移動させることにより、一対の側方反射板112の開口角度を、容易に変更することができる。 As described above, according to the strobe device of the present embodiment, the opening angle of the pair of side reflection plates 112 can be easily changed by moving the light emitting unit 1 in the Y direction in the casing 2. it can.
 また、本実施の形態のストロボ装置によれば、発光部1をケーシング2内で移動させるだけで、一対の側方反射板112の開口角度を変更することができる。つまり、ケーシング2内で移動させて発光部1のホルダー12の姿勢を転換させることにより、一対の側方反射板112の開口角度を変更できる。その結果、ストロボ装置を大型化せずに、小型を維持できる。 Further, according to the strobe device of the present embodiment, the opening angle of the pair of side reflection plates 112 can be changed only by moving the light emitting unit 1 in the casing 2. That is, the opening angle of the pair of side reflection plates 112 can be changed by moving the inside of the casing 2 to change the posture of the holder 12 of the light emitting unit 1. As a result, compactness can be maintained without increasing the size of the strobe device.
 なお、本発明は、上記実施の形態に限定することなく、種々変更することができる。 The present invention can be variously modified without being limited to the above embodiment.
 例えば、上記実施の形態では、一対の側方反射板に当接部を備えた例で説明したが、これに限られない。つまり、一対の側方反射板に当接部を設けず、反射部がホルダーで直接、押される構成としてもよい。これにより、構造を簡略にできる。 For example, although the said embodiment demonstrated the example which provided the contact part in a pair of side reflection plate, it is not restricted to this. That is, without providing the contact portion on the pair of side reflection plates, the reflection portion may be directly pressed by the holder. This can simplify the structure.
 また、上記実施の形態では、一対の側方反射板が、反射部の反射傘から照射対象に向けられた光軸を対称軸として揺動する例で説明したが、これに限られない。例えば、一対の側方反射板が、非対称に揺動する構成としてもよい。これにより、より正確に照射角の変更を実施できる。 Moreover, although the said embodiment demonstrated the example which a pair of side reflectors rock | fluctuates by the optical axis turned to irradiation object from the reflector of a reflection part as a symmetry axis, it is not restricted to this. For example, the pair of side reflectors may be configured to swing asymmetrically. Thereby, change of an irradiation angle can be implemented more correctly.
 また、上記実施の形態では、両端部が開口したタイプの反射傘を用いた例で説明したが、これに限られない。例えば、反射傘の両端部を閉塞する反射部を有する反射傘の構成でもよい。この場合、一対の側方反射板は、反射傘の両端部の反射部よりも、照射対象側である前側に配置する。これにより、光の利用効率を向上させることができる。 Moreover, although the said embodiment demonstrated the example using the reflector of the type which the both ends opened, it is not restricted to this. For example, the configuration of a reflector having a reflection part that closes both ends of the reflector may be used. In this case, the pair of side reflectors is disposed on the front side, which is the side to be irradiated, with respect to the reflecting portions at both ends of the reflector. Thereby, the utilization efficiency of light can be improved.
 また、上記実施の形態では、ケーシングに設けたカム面と、ホルダーに設けた従動部とによって、ホルダーが傾動する構成を例に説明したが、これに限られない。例えば、カム面や従動部を備えることなく、ホルダーの移動により、ホルダーを傾動する構成としてもよい。これにより、部品点数を削減した上で同様の効果が得られる。 Moreover, although the said embodiment demonstrated the structure which a holder tilts with the cam surface provided in the casing, and the follower part provided in the holder as an example, it is not restricted to this. For example, the holder may be tilted by movement of the holder without providing a cam surface or a follower. Thereby, the same effect can be obtained after the number of parts is reduced.
 また、上記実施の形態では、ホルダーの押圧部と一対の側方反射板の当接部との当接により、一対の側方反射板の開口角度を変更する例で説明したが、これに限られない。例えば、ケーシングの底板部のX方向の左右に、ケーシングの閃光透過部側に向かって、少なくとも内側に広がる壁面を備える凹部形状の一対のカム面を設ける。さらに、一対のカム面の壁面に沿って移動する一対の従動部を設ける。そして、一対のカム面の壁面に沿って移動する一対の従動部により、一対の側方反射板の開口角度を変更する構成としてもよい。これにより、簡易な構成で照射角変更が可能となる。 Further, in the above embodiment, the example in which the opening angle of the pair of side reflection plates is changed by the contact between the pressing portion of the holder and the contact portion of the pair of side reflection plates has been described. I can not. For example, on the left and right sides of the bottom plate portion of the casing in the X direction, a pair of cam surfaces in the form of recesses is provided with a wall surface that extends at least inwardly toward the flashlight transmitting portion side of the casing. Furthermore, a pair of follower parts which move along the wall surface of a pair of cam surface are provided. Then, the opening angles of the pair of side reflection plates may be changed by the pair of driven parts moving along the wall surfaces of the pair of cam surfaces. Thereby, the irradiation angle can be changed with a simple configuration.
 以下に、上記実施の形態の別の例に係るストロボ装置の構成について、図9Aおよび図9Bを用いて、具体的に説明する。 The configuration of the strobe device according to another example of the above embodiment will be specifically described below with reference to FIGS. 9A and 9B.
 図9Aは、本発明の実施の形態に係るストロボ装置の別の例であって、カム面の壁面に沿って、従動部が望遠撮影状態に移動した状態を模式的に説明する概略説明図である。図9Bは、同ストロボ装置の別の例であって、カム面の壁面に沿って、従動部が広角撮影状態に移動した状態を模式的に説明する概略説明図である。 FIG. 9A is another example of the flash device according to the embodiment of the present invention, and is a schematic explanatory view schematically illustrating a state where the driven unit is moved to the telephoto shooting state along the wall surface of the cam surface. is there. FIG. 9B is another example of the flash device, and is a schematic explanatory view schematically illustrating a state in which the driven unit moves to the wide-angle shooting state along the wall surface of the cam surface.
 なお、別の例に係るストロボ装置の一対のカム面310および一対の従動部300においては、上記実施の形態のカム面221および従動部123と区別するために、以下では第2のカム面310および第2の従動部300と記して説明する。 Note that, in the pair of cam surfaces 310 and the pair of driven parts 300 of the flash device according to another example, in order to distinguish from the cam surface 221 and the driven part 123 of the above embodiment, the second cam surfaces 310 will be described below. And the second follower 300 will be described.
 図9Aおよび図9Bに示すように、本実施の形態の別の例のストロボ装置は、ケーシング2の底板部22に設けた第2のカム面310と、ホルダー12に設けられた第2の従動部300と、一対の側方反射板112に設けられた回動支持部320を備えている。それ以外の構成は、上記実施の形態と同様であるので、説明を省略する。 As shown in FIGS. 9A and 9B, the strobe device of another example of the present embodiment includes a second cam surface 310 provided on the bottom plate portion 22 of the casing 2 and a second follower provided on the holder 12. A portion 300 and a pivot support portion 320 provided on the pair of side reflection plates 112 are provided. The other configuration is the same as that of the above-described embodiment, and thus the description thereof is omitted.
 第2のカム面310は、ケーシング2の底板部22の中心線に対して、X方向の左右に設けられ、壁面310aを有する凹部形状で形成されている。第2のカム面310の少なくとも内側の壁面310aは、ケーシング2の背面部24から閃光透過部25に向かって、内側に広がるように、例えば湾曲状または直線状に設けられている。第2の従動部300は、ホルダー12のZ方向の下方に突出して、ホルダー12に設けられている。回動支持部320は、第2の従動部300が挿入される回動穴320aを有し、一対の側方反射板112に設けられ、フレーム14の支軸部143に軸支されている。そして、回動支持部320は、回動穴320aに挿入された第2の従動部300が、第2のカム面310の壁面310aに沿って移動する移動にともなって、一対の側方反射板112の開口角度を変更する。このとき、一対の側方反射板112は、図示しないバネなどの付勢部材により、第2のカム面310の壁面310aに、常に付勢されている。これにより、第2の従動部300は、第2のカム面310の壁面310aに沿って移動する。それ以外の構成は、上記実施の形態と同様であるので、説明を省略する。 The second cam surface 310 is provided on the left and right in the X direction with respect to the center line of the bottom plate portion 22 of the casing 2 and is formed in a concave shape having a wall surface 310 a. At least the inner wall surface 310 a of the second cam surface 310 is provided, for example, in a curved or straight shape so as to extend inward from the back surface portion 24 of the casing 2 toward the flashlight transmitting portion 25. The second follower 300 is provided on the holder 12 so as to protrude downward in the Z direction of the holder 12. The rotation support portion 320 has a rotation hole 320 a into which the second driven portion 300 is inserted, is provided in the pair of side reflection plates 112, and is pivotally supported by the support shaft portion 143 of the frame 14. The rotation support portion 320 is a pair of side reflection plates as the second driven portion 300 inserted in the rotation hole 320 a moves along the wall surface 310 a of the second cam surface 310. Change the opening angle of 112. At this time, the pair of side reflection plates 112 is always biased to the wall surface 310 a of the second cam surface 310 by a biasing member such as a spring (not shown). Thereby, the second follower 300 moves along the wall surface 310 a of the second cam surface 310. The other configuration is the same as that of the above-described embodiment, and thus the description thereof is omitted.
 つまり、ホルダー12の第2の従動部300は、第2のカム面310の壁面310aに沿って、駆動部3のモータ31の駆動により、図9Aに示すケーシング2の背面部24側から、図9Bに示す閃光透過部25に移動する。これにより、図9Aに示す望遠撮影状態の一対の側方反射板112の開口角度から、図9Bに示す広角撮影状態の一対の側方反射板112の開口角度に変更することができる。 That is, the second driven unit 300 of the holder 12 is shown from the back surface 24 side of the casing 2 shown in FIG. 9A by driving the motor 31 of the drive unit 3 along the wall surface 310a of the second cam surface 310. It moves to the flashlight transmitting portion 25 shown in 9B. Thus, the opening angles of the pair of side reflection plates 112 in the telephoto shooting state shown in FIG. 9A can be changed to the opening angles of the pair of side reflection plates 112 in the wide angle shooting state shown in FIG. 9B.
 上述したように、本実施の形態の別の例のストロボ装置によれば、発光部1をケーシング2内でY方向に移動させることにより、一対の側方反射板112の開口角度を、容易に変更することができる。 As described above, according to the strobe device of another example of the present embodiment, by moving the light emitting unit 1 in the Y direction in the casing 2, the opening angle of the pair of side reflectors 112 can be easily made. It can be changed.
 つまり、ケーシング2内で、第2のカム面310の壁面310aに沿って、発光部1を移動させることにより、一対の側方反射板112の開口角度を変更できる。その結果、ストロボ装置を大型化することなく、小型に維持できる。 That is, by moving the light emitting unit 1 along the wall surface 310 a of the second cam surface 310 in the casing 2, the opening angles of the pair of side reflection plates 112 can be changed. As a result, the electronic flash device can be kept compact without increasing the size of the electronic flash device.
 以上で説明したように、本発明のストロボ装置は、閃光を発する光源と、光源から発せられた閃光を照射対象に向けて反射させる反射部とを備える発光部と、光源で発した閃光を透過させる閃光透過部を有し、閃光透過部に光源を向き合わせるように発光部を収納するケーシングと、発光部をケーシング内で閃光透過部に接離する方向に往復動させる駆動部とを備える。発光部の反射部は、閃光透過部に向けられた反射傘と、照射対象に向ける閃光の照射角を変更できるように反射傘に隣り合って揺動可能に配置された一対の側方反射板とを備える。そして、一対の側方反射板は、発光部の往復動に連動して揺動することにより、開口角度を変更可能な構成としてもよい。 As described above, the strobe device of the present invention transmits the flash light emitted from the light source by the light emitting unit including the light source emitting the flash light and the reflecting portion reflecting the flash light emitted from the light source toward the irradiation target And a casing for housing the light emitting unit so as to face the light source to the flash light transmitting unit, and a drive unit for reciprocating the light emitting unit in a direction in which the light emitting unit is in contact with and separated from the flash light transmitting unit. The reflecting portion of the light emitting portion is a reflector directed to the flash light transmitting portion, and a pair of side reflecting plates arranged swingably adjacent to the reflector so as to be able to change the irradiation angle of the flash light directed to the irradiation object And The pair of side reflectors may be configured to be able to change the opening angle by swinging in conjunction with the reciprocating motion of the light emitting unit.
 この構成によれば、光源から発せられた閃光は、反射部、すなわち、反射傘と一対の側方反射板とで反射する。そして、反射した閃光は、ケーシングの閃光透過部を透過して照射対象を照射する。このとき、反射部の一対の側方反射板は、ケーシング内で、発光部の往復動に連動して揺動する、これにより、一対の側方反射板の開口角度が変更される。その結果、照射対象に向けて反射する閃光の照射角を変更することができる。 According to this configuration, the flashlight emitted from the light source is reflected by the reflective portion, that is, the reflector and the pair of side reflectors. Then, the reflected flash light passes through the flash light transmitting portion of the casing to irradiate the irradiation target. At this time, the pair of side reflection plates of the reflection portion is rocked in conjunction with the reciprocation of the light emitting portion in the casing, whereby the opening angle of the pair of side reflection plates is changed. As a result, it is possible to change the irradiation angle of the flashlight reflected toward the irradiation target.
 具体的には、発光部がケーシングの背面側(閃光透過部の反対側)に位置している場合、発光部の移動に連動して一対の側方反射板が揺動し、一対の側方反射板の開口角度が広くなる。これにより、光源から発した閃光は、望遠撮影に適した狭い照射角となった一対の側方反射板で反射する。一方、発光部がケーシングの閃光透過部側に位置している場合、発光部の移動に連動して一対の側方反射板が揺動し、一対の側方反射板の開口角度が狭くなる。これにより、光源から発した閃光は、広角撮影に適した狭い照射角となった一対の側方反射板で反射する。 Specifically, when the light emitting unit is located on the back side of the casing (the opposite side of the flash light transmitting unit), the pair of side reflection plates swings in conjunction with the movement of the light emitting unit, and the pair of side reflectors The aperture angle of the reflecting plate is broadened. As a result, the flashlight emitted from the light source is reflected by the pair of side reflection plates having a narrow illumination angle suitable for telephoto shooting. On the other hand, when the light emitting portion is located on the side of the flashlight transmitting portion of the casing, the pair of side reflectors swings in conjunction with the movement of the light emitting portion, and the opening angle of the pair of side reflectors narrows. As a result, the flashlight emitted from the light source is reflected by the pair of side reflection plates which has a narrow illumination angle suitable for wide-angle shooting.
 その結果、光学設計条件を限定することなく、小型化が図れるとともに、光源から発せられた閃光の照射角を可変にできるストロボ装置を実現できる。 As a result, without limiting the optical design conditions, miniaturization can be achieved, and a strobe device can be realized in which the irradiation angle of the flash light emitted from the light source can be made variable.
 また、本発明のストロボ装置は、発光部が、光源を保持するホルダーと、反射傘を保持するとともに一対の側方反射板を軸支するフレームと、をさらに備える。そして、ホルダーとフレームとは、個別に移動可能に設けられ、反射傘から照射対象に向けられた光軸を対称軸にして、一対の側方反射板がホルダーの移動によって揺動する構成としてもよい。 In the strobe device of the present invention, the light emitting unit further includes a holder for holding the light source, and a frame for holding the reflector and pivotally supporting the pair of side reflection plates. The holder and the frame are provided so as to be movable individually, and the pair of side reflectors are swung by the movement of the holder with the optical axis directed from the reflector to the irradiation target as the axis of symmetry. Good.
 この構成によれば、発光部に備えられたホルダーとフレームとが、個別に移動する。これにより、フレームが移動しながら、ホルダーがフレームに軸支された一対の側方反射板を押すことができる。その結果、一対の側方反射板の開口角度を、容易に変更することができる。 According to this configuration, the holder and the frame provided in the light emitting unit move individually. Thus, while the frame is moving, the holder can press the pair of side reflectors pivotally supported by the frame. As a result, the opening angle of the pair of side reflectors can be easily changed.
 また、本発明のストロボ装置は、ホルダーが、一対の側方反射板に向けて突出した押圧部を備え、一対の側方反射板は、閃光を反射する反射部材と、反射部材に突設されたホルダーの押圧部に押される当接部とを備えてもよい。 Further, in the strobe device of the present invention, the holder includes a pressing portion protruding toward the pair of side reflection plates, and the pair of side reflection plates are provided so as to protrude from the reflection member reflecting the flash light and the reflection member The holder may further include a contact portion pressed by the pressing portion of the holder.
 この構成によれば、ホルダーの押圧部が、一対の側方反射板の当接部を押す。これにより、一対の側方反射板の開口角度を変更することができる。また、ホルダーの押圧部で、一対の側方反射板の反射部材を押さない構成とできる、これにより、一対の側方反射板の反射部材が凹むなどの不具合を未然に防止できる。その結果、常に、発光部から均一な閃光を発生して、照射対象を照明できるストロボ装置を実現できる。 According to this configuration, the pressing portion of the holder presses the contact portion of the pair of side reflection plates. Thereby, the opening angle of the pair of side reflectors can be changed. In addition, the pressing member of the holder can be configured not to press the reflecting members of the pair of side reflectors. This can prevent problems such as the reflecting members of the pair of side reflectors being recessed. As a result, it is possible to realize a strobe device capable of illuminating the object to be illuminated by always generating uniform flash light from the light emitting unit.
 また、本発明のストロボ装置は、ケーシングが、凹部および凸部を有するカム面を備え、ホルダーは、カム面に接触する従動部を備える。そして、ホルダーの従動部がケーシングのカム面に沿って移動することにより、ホルダーが傾動する構成としてもよい。 Further, in the strobe device of the present invention, the casing includes a cam surface having a recess and a protrusion, and the holder includes a follower that contacts the cam surface. The holder may be configured to be tilted by moving the driven portion of the holder along the cam surface of the casing.
 この構成によれば、ケーシングにカム面が備えられ、ホルダーに従動部が備えられ、従動部がケーシングに備えられたカム面に接触する。そして、発光部が閃光の光軸方向に往復動する際に、従動部がカム面の凹部および凸部に沿って移動することにより、ホルダーは仰向き姿勢から俯き姿勢に傾動する。このとき、仰向き姿勢に傾動したホルダーは、一対の側方反射板を押さないので、一対の側方反射板の開口角度は望遠撮影の状態に維持できる。一方、俯き姿勢に傾動したホルダーは、一対の側方反射板を押して、一対の側方反射板の開口角度を狭めて広角撮影の状態にできる。その結果、ホルダーの傾動により、一対の側方反射板の開口角度は望遠撮影から広角撮影に容易に変更できる。 According to this configuration, the casing is provided with the cam surface, the holder is provided with the follower, and the follower is in contact with the cam surface provided in the casing. Then, when the light emitting part reciprocates in the optical axis direction of the flash light, the holder moves from the reclining posture to the unfolded posture as the follower moves along the concave and convex portions of the cam surface. At this time, since the holder tilted in the supposing position does not press the pair of side reflection plates, the opening angle of the pair of side reflection plates can be maintained in the state of telephoto shooting. On the other hand, the holder tilted to the unfolded position can push the pair of side reflectors to narrow the opening angle of the pair of side reflectors to obtain a wide-angle shooting state. As a result, by the tilting of the holder, the aperture angles of the pair of side reflectors can be easily changed from telephoto shooting to wide-angle shooting.
 また、本発明のストロボ装置は、発光部が、ホルダーとフレームとの間に介在し、ホルダーを仰向き姿勢とする付勢部材を、さらに備える。そして、ホルダーは、従動部がケーシングのカム面に沿って移動することにより、俯き姿勢になる構成としてもよい。 Further, in the strobe device of the present invention, the light emitting unit further includes an urging member interposed between the holder and the frame and setting the holder in the supposing position. Then, the holder may be configured to be in the winding posture by moving the follower along the cam surface of the casing.
 この構成によれば、ホルダーは、付勢部材によって、定常状態において、仰向き姿勢を維持することができる。そして、ホルダーを移動させることにより、付勢部材の付勢力に抗して、発光部は俯き姿勢に転換して、一対の側方反射板を押す状態となる。これにより、一対の側方反射板の開口角度は望遠撮影から広角撮影に容易に変更できる。 According to this configuration, the holder can maintain the reclining posture in the steady state by the biasing member. Then, by moving the holder, the light emitting unit is switched to the unfolded posture against the biasing force of the biasing member, and the pair of side reflectors is pushed. Thus, the aperture angle of the pair of side reflectors can be easily changed from telephoto shooting to wide-angle shooting.
 また、本発明のストロボ装置は、発光部が、一対の側方反射板とフレームとの間に介在し、一対の側方反射板の開口角度を広くする弾性部材を、さらに備える。そして、一対の側方反射板の開口角度は、発光部が移動することにより、狭くなるように構成としてもよい。 In the strobe device of the present invention, the light emitting unit further includes an elastic member interposed between the pair of side reflectors and the frame to widen the opening angle of the pair of side reflectors. The opening angles of the pair of side reflectors may be narrowed by moving the light emitting unit.
 この構成によれば、一対の側方反射板とフレームとの間に介在した弾性部材により、一対の側方反射板の開口角度を、定常状態において、広く開口した姿勢で維持できる。そして、ホルダーを移動させることにより、一対の側方反射板の開口角度を狭くすることができる。これにより、一対の側方反射板の開口角度を望遠撮影から広角撮影に容易に変更できる。 According to this configuration, the elastic members interposed between the pair of side reflection plates and the frame can maintain the opening angles of the pair of side reflection plates in a wide open posture in the steady state. Then, by moving the holder, the opening angle of the pair of side reflectors can be narrowed. Thus, the aperture angle of the pair of side reflectors can be easily changed from telephoto shooting to wide-angle shooting.
 また、本発明のストロボ装置によれば、ケーシングは、閃光透過部に向かって内側に広がる壁面を有するカム面を備え、発光部は、光源を保持するホルダーと、回動支持部を有する一対の側方反射板を軸支するフレームを備える。ホルダーは、回動支持部を回動自在に連結する従動部を、さらに備える。そして、ホルダーの従動部が、ケーシングのカム面の壁面に沿って移動することにより、回動支持部を介して一対の側方反射板が揺動する構成としてもよい。 Further, according to the strobe device of the present invention, the casing includes a cam surface having a wall surface extending inward toward the flash light transmitting portion, and the light emitting portion includes a holder for holding the light source and a pair of pivoting support portions. A frame pivotally supports the side reflectors. The holder further includes a follower which rotatably connects the rotation support. Then, when the driven portion of the holder moves along the wall surface of the cam surface of the casing, the pair of side reflection plates may be swung via the rotation support portion.
 この構成によれば、一対の側方反射板は、ケーシング内で、発光部の往復動に連動して揺動する、これにより、一対の側方反射板の開口角度が変更される。その結果、照射対象に向けて反射する閃光の照射角を変更することができる。 According to this configuration, the pair of side reflection plates is rocked in conjunction with the reciprocation of the light emitting unit in the casing, whereby the opening angle of the pair of side reflection plates is changed. As a result, it is possible to change the irradiation angle of the flashlight reflected toward the irradiation target.
