Description

本発明は、夜間など、自然光が不足な状態で写真撮影を行うときに、自然光の補助としてシャッターの作動に連動して発光させられるストロボ装置に係るものであり、詳細にはカメラに一体化して組み込めるように、特に発光部である投光レンズの小形化が要求されるストロボ装置に関するものである。   The present invention relates to a strobe device that emits light in conjunction with the operation of a shutter as an auxiliary to natural light when taking a picture in a state where natural light is insufficient, such as at night, and is specifically integrated with a camera. In particular, the present invention relates to a strobe device that requires a miniaturization of a projection lens that is a light emitting portion.

従来の発光部の小形化を図ったストロボ装置90としては、図4に示すようなものが開示されており、直接に光を外部に放射する発光部を小形化するために、例えば、カメラ本体80の右上部に設けられているストロボ装置90の投光レンズ91の表面に、ストロボ装置90から光を採取するための複数の光ファイバー92の一端を取付ける。   As a conventional strobe device 90 for reducing the size of a light emitting unit, a device as shown in FIG. 4 is disclosed. In order to reduce the size of a light emitting unit that directly emits light to the outside, for example, a camera body One end of a plurality of optical fibers 92 for collecting light from the strobe device 90 is attached to the surface of the light projecting lens 91 of the strobe device 90 provided at the upper right portion of 80.

そして、前記光ファイバー92の他端を、カメラ本体80の撮影レンズ81の外径に固定し、撮影レンズ81の周縁から光が放射されるようにしておく。このようにすることで、撮影レンズ81としての太さには実質的に影響を与えることなく、例えば、撮影レンズ81を挿入して口腔中の写真の撮影を可能とするものである。
特開2005−046388号公報
The other end of the optical fiber 92 is fixed to the outer diameter of the photographing lens 81 of the camera body 80 so that light is emitted from the periphery of the photographing lens 81. In this way, for example, the photographing lens 81 can be inserted to take a picture in the oral cavity without substantially affecting the thickness of the photographing lens 81.
JP 2005-046388 A

しかしながら、上記した従来のストロボ装置90の発光部の小形化手段は、確かに、口腔中など狭い場所の撮影を可能とするという利点は認められるものの、第一には、光ファイバー92により集めることのできる光量はストロボ装置90が発生する光量に対して、ごく一部に過ぎず、一般の使用時において、少ない外光を補うという本来の目的が達成できず、カメラ本体80の汎用性が失われるという問題点を生じる。   However, although the above-described conventional means for reducing the size of the light emitting portion of the strobe device 90 has the advantage of enabling photographing in a narrow place such as in the oral cavity, first of all, it is collected by the optical fiber 92. The amount of light that can be produced is only a fraction of the amount of light generated by the strobe device 90, and the original purpose of compensating for a small amount of external light cannot be achieved during general use, and the versatility of the camera body 80 is lost. This causes the problem.

また、第二には、例え光量の問題は解決したとしても、光ファイバー92、即ち導光部材がカメラ本体80の筐体よりも外側に引き回されている形状は、使用中の外部機材との接触などによる破損を生じ易いものとなり、また、外観上にも違和感を与えるものとなり、破損しやすく、且つ、外観を損なうものとなる問題点を併せて生じるものとなる。   Second, even if the problem of the light quantity is solved, the shape of the optical fiber 92, that is, the light guide member drawn outside the housing of the camera body 80 is different from the external equipment in use. It becomes easy to cause damage due to contact and the like, and also gives a sense of discomfort to the external appearance, and also causes problems that are easy to break and impair the external appearance.

本発明は、上記した従来の課題を解決するための具体的手段として、管状光源と、この管状光源を第一焦点として少なくとも前記光源の有効長と同一の幅を有する楕円柱状面とし、前記管状光源の中心で第二焦点の位置が上下方向に分割して生じるように形成された反射面と、前記光源の前方には透明部材により、この光源からの直射光に対する光取入口が設けられた略二股状に形成され前記光源からの光を上下方向に分割し、前記略二股状の内面側が、前記光源を第一焦点とし、第二焦点を前記反射面の第二焦点の近傍とする楕円柱状面とし、外面側が平面の鏡面とされた導光部材と、前記反射面と前記導光部材とによる2箇所の焦点にそれぞれ対応して設けられた一対のシリンドリカルレンズ状とした投光レンズとから成るストロボ装置を提供することで課題を解決するものである。   The present invention provides, as specific means for solving the above-described conventional problems, a tubular light source, and an elliptical columnar surface having at least the same width as the effective length of the light source with the tubular light source as a first focal point. A reflection surface formed so that the position of the second focal point is divided in the vertical direction at the center of the light source, and a light inlet for direct light from the light source is provided by a transparent member in front of the light source. An ellipse that is formed in a substantially bifurcated shape and divides the light from the light source in the vertical direction, and the substantially bifurcated inner surface side has the light source as the first focal point and the second focal point in the vicinity of the second focal point of the reflecting surface. A light guide member having a columnar surface and a mirror surface having a flat outer surface side; and a pair of cylindrical lens-shaped light projecting lenses provided corresponding to two focal points of the reflection surface and the light guide member; Strobe device consisting of It solves the problem by providing.

本発明により、第一焦点から発せられる光を第二焦点に集束する楕円柱状面を反射面に採用すると共に、前記反射面に当たらない光を、同様に楕円柱状面を採用した導光部材で捕捉し、且つ、両者の第二焦点をほぼ同じ位置に発生させ、この第二焦点を焦点とする投光レンズで外部に放射するものとしたことで、光源から発せられる光量に対する光束捕捉率を向上させ、明るいストロボ装置の実現を可能とするものである。   According to the present invention, the elliptical columnar surface that focuses the light emitted from the first focal point to the second focal point is adopted as the reflecting surface, and the light that does not hit the reflecting surface is similarly adopted by the light guiding member that adopts the elliptical columnar surface. By capturing and generating the second focal point of both at substantially the same position and emitting to the outside by a projection lens having the second focal point as a focal point, the luminous flux capturing rate with respect to the light amount emitted from the light source can be obtained. It is possible to improve and realize a bright strobe device.

つぎに、本発明を図に示す実施形態に基づいて詳細に説明する。図1に示すものは、本発明に係るストロボ装置1の断面図であり、このストロボ装置1は光源であるキセノン放電管2と、前記キセノン放電管2からの発光を照射方向に向かわせるべく反射する反射面3と、例えば、アクリル樹脂、ポリカーボネート樹脂など、透明な樹脂で形成された導光部材5と、前記導光部材5と同様に透明部材で形成された投光レンズ4とを主なる部品として形成されている。   Below, this invention is demonstrated in detail based on embodiment shown in a figure. FIG. 1 is a cross-sectional view of a strobe device 1 according to the present invention. This strobe device 1 reflects a xenon discharge tube 2 that is a light source and light emitted from the xenon discharge tube 2 in the irradiation direction. The reflecting surface 3 is mainly composed of a light guide member 5 formed of a transparent resin such as acrylic resin or polycarbonate resin, and a light projecting lens 4 formed of a transparent member similar to the light guide member 5. It is formed as a part.

ここで、本発明のストロボ装置1においては、前記キセノン放電管2の長手方向に沿う中心線を通る水平線Hに対して、ほぼ全ての部分が上下が線対称に形成されるものであり、このとき、前記キセノン放電管2は、本発明においても、従来から、この種のストロボ装置1に採用されているものと、特に変わるものではなく、所定の長さを有する管状光源である。   Here, in the stroboscopic device 1 of the present invention, almost all of the portions are formed symmetrically with respect to the horizontal line H passing through the center line along the longitudinal direction of the xenon discharge tube 2. In the present invention, the xenon discharge tube 2 is a tubular light source having a predetermined length, which is not particularly different from that conventionally used in this type of strobe device 1.

先ず、前記反射面3について説明を行えば、この反射面3は前記水平線Hを境として、上部反射面3aと下部反射面3bとが形成されているものであり、そして,本発明では、上部反射面3aも下部反射面3bも、前記キセノン放電管2の中心を第一焦点とする楕円柱面として形成されている。   First, the reflective surface 3 will be described. The reflective surface 3 is formed with an upper reflective surface 3a and a lower reflective surface 3b with the horizontal line H as a boundary. Both the reflection surface 3a and the lower reflection surface 3b are formed as elliptical cylinder surfaces having the center of the xenon discharge tube 2 as a first focal point.

そして、前記上部反射面3aの第二焦点f2は、前記したように水平線Hに対して線対称に2箇所に形成された前記投光レンズ4の内の上投光レンズ4aの焦点、若しくはその近傍の位置に設けられている。同様に下部反射面3bの第二焦点(図示せず)は、下投光レンズ4bの焦点、若しくはその近傍の位置に設けられている。   The second focal point f2 of the upper reflecting surface 3a is the focal point of the upper light projecting lens 4a of the light projecting lenses 4 formed symmetrically with respect to the horizontal line H as described above, or the focus thereof. It is provided in the vicinity. Similarly, the second focal point (not shown) of the lower reflecting surface 3b is provided at the focal point of the lower light projecting lens 4b or in the vicinity thereof.

ここで、再度、前記キセノン放電管2について述べれば、このキセノン放電管2は管状バルブにより形成されているものであるので、図1においては、前記水平線Hに対し紙面方向で直交する線状であり、その線状の光を第一焦点とする前記反射面3(a、b)が集束する第二焦点f2も同様に線状である。   Here, again, the xenon discharge tube 2 will be described. Since the xenon discharge tube 2 is formed by a tubular bulb, in FIG. The second focal point f2 at which the reflecting surface 3 (a, b) having the linear light as the first focal point is also linear.

よって、前記第二焦点を照射方向に投射する上下の投光レンズ4(a、b)も同様に線状、即ち、シリンドリカルレンズ状として形成されている。尚、左右の両端を円弧状とする。あるいは左右方向への拡散を行うように投光レンズ4(a、b)の裏面にプリズムカットを施すなどは、デザイン的な見地、あるいは所望の照射角を得るなど必要に応じて、行えば良いものである。   Accordingly, the upper and lower light projecting lenses 4 (a, b) that project the second focal point in the irradiation direction are also formed in a linear shape, that is, in a cylindrical lens shape. The left and right ends are arcuate. Alternatively, a prism cut or the like may be performed on the back surface of the light projecting lens 4 (a, b) so as to perform diffusion in the left-right direction, as needed, for example, to obtain a desired irradiation angle. Is.

ついで、導光部材5について説明を行う。この導光部材5には、一箇所の光取入口5aと、二箇所の光取出口5bとが設けられていて、前記光取入口5aは、前記キセノン放電管2の中心と同芯の曲面として形成され、これにより、前記キセノン放電管2から発光されて前記光取入口5aに達した光は、略直角に導光部材5内に入射するものとなり、効率良く導光部材5内に取込まれるものとなる。   Next, the light guide member 5 will be described. The light guide member 5 is provided with one light inlet 5 a and two light outlets 5 b, and the light inlet 5 a is a curved surface concentric with the center of the xenon discharge tube 2. Thus, the light emitted from the xenon discharge tube 2 and reaching the light inlet 5a enters the light guide member 5 at a substantially right angle, and is efficiently taken into the light guide member 5. It will be included.

そして、前記導光部材5は、光取入口5aの後方で二方向に分岐され、前記光取入口5aから入射した光を前記反射面3と同様に上下方向に二分する。このときに、前記導光部材5の二股状に分岐された内面5cの双方は、前記キセノン放電管2を第一焦点とする楕円柱面状に形成され、後に説明する所定の位置に第二焦点fgを有するものとされている。   The light guide member 5 is branched in two directions behind the light intake 5a, and divides light incident from the light intake 5a in the vertical direction in the same manner as the reflection surface 3. At this time, both of the bifurcated inner surface 5c of the light guide member 5 are formed in an elliptical columnar shape with the xenon discharge tube 2 as a first focal point, and are in a predetermined position described later. It has a focal point fg.

また、前記導光部材5の外面5dは、平面として形成され、例えば、屈折率差による全反射面、あるいは、アルミニウムなどの蒸着が行われた反射面とし、鏡面6とされている。このときに、前記した導光部材5の内面5cに形成された楕円柱面の第二焦点は、図2中に第二焦点fgで示すように、前記鏡面6を超えた位置に形成されている。   Further, the outer surface 5d of the light guide member 5 is formed as a flat surface, and is a mirror surface 6, for example, a total reflection surface due to a difference in refractive index or a reflection surface on which vapor deposition of aluminum or the like is performed. At this time, the second focal point of the elliptical cylindrical surface formed on the inner surface 5c of the light guide member 5 is formed at a position beyond the mirror surface 6 as indicated by the second focal point fg in FIG. Yes.

このようにしたことで、前記内面5cで反射した光は、第二焦点fgに収束される途上の状態で鏡面6に達し、光取出口5bの方向に向かい、外部に放射された後に収束して前記投影レンズ4の焦点fと略等しい位置に第二焦点fg’を結ぶものとなる。   By doing in this way, the light reflected by the inner surface 5c reaches the mirror surface 6 while being converged to the second focal point fg, travels toward the light outlet 5b, and converges after being emitted to the outside. Thus, the second focal point fg ′ is formed at a position substantially equal to the focal point f of the projection lens 4.

本発明では、前記反射面3(上部反射面3aと下部反射面3b)の第二焦点f2に対応しては、この第二焦点の近傍に焦点を有する投光レンズ4(4a、4b)が設けられているものであり、前記導光部材5の二つの光取出口5b、5bも、同様に前記投光レンズ4(4a、4b)の焦点の近傍に位置が設定されている。   In the present invention, the projection lens 4 (4a, 4b) having a focal point in the vicinity of the second focal point corresponds to the second focal point f2 of the reflective surface 3 (upper reflective surface 3a and lower reflective surface 3b). Similarly, the positions of the two light outlets 5b and 5b of the light guide member 5 are set in the vicinity of the focal point of the light projecting lens 4 (4a and 4b).

従って、前記投光レンズ4(4a、4b)の近傍には、前記反射面3(3a、3b)により形成される第二焦点f2と、前記導光部材5により形成される第二焦点fg’とが、各2本宛、存在するものとなる。このことは、図1からも理解できるように、前記キセノン放電管2から放射される光のほぼ全てを第二焦点として集束した状態で、前記投光レンズ4(4a、4b)に入射させるものであるので、キセノン放電管2に対する光束利用率を、従来例のものに比較して格段に向上させることが可能となる。   Accordingly, in the vicinity of the light projecting lens 4 (4a, 4b), a second focal point f2 formed by the reflecting surface 3 (3a, 3b) and a second focal point fg ′ formed by the light guide member 5 are provided. Are present for each of the two. As can be understood from FIG. 1, this is a state in which almost all of the light emitted from the xenon discharge tube 2 is incident on the light projecting lens 4 (4a, 4b) while being focused as a second focal point. Therefore, the luminous flux utilization factor for the xenon discharge tube 2 can be remarkably improved as compared with the conventional example.

尚、図中に符号7で示すものは遮蔽板であり、一対の前記投光レンズ4を一体化して形成したときなどには、上投光レンズ4aと下投光レンズ4bとの間のレンズ接続面4cも透明部材で形成されるものとなり、例えば非点灯時には、このレンズ接続面4c部分を透視して内部構造が見えたり、あるいは、点灯時に、このレンズ接続面4cから内部で生じた迷光が放射されて、配光、デザインを乱すなどを防止する目的で、不透明な板状などとして取付けられるものである。   In the figure, reference numeral 7 denotes a shielding plate. When a pair of the projection lenses 4 are formed integrally, the lens between the upper projection lens 4a and the lower projection lens 4b is used. The connection surface 4c is also formed of a transparent member. For example, when not lit, the internal structure can be seen through the lens connection surface 4c, or stray light generated from the lens connection surface 4c when lit. Is attached as an opaque plate or the like for the purpose of preventing the light distribution and design from being disturbed.

図2及び図3は、本発明に係るストロボ装置1の第二実施例であり、主として、前記レンズ接続面4cを改良することで、カメラに組込んだときにも斬新なデザインが得られるようにするものであり、また、遮蔽板7も不要として、構成の簡素化も可能とするものである。   2 and 3 show a second embodiment of the strobe device 1 according to the present invention. By mainly improving the lens connecting surface 4c, a novel design can be obtained even when incorporated in a camera. In addition, since the shielding plate 7 is not required, the configuration can be simplified.

この目的を達するために、図2に示すように、投影レンズ4における、上投影レンズ4aと下投影レンズ4b間のレンズ接続面4cは平坦面としておき、前記投影レンズ4自体、言い換えればストロボ装置1全体をカメラ本体20の内部に取付け、前記上投影レンズ4aと下投影レンズ4bのみを、前記カメラ本体20に設けたスリット状孔20aから外部に臨ませるものである。   In order to achieve this purpose, as shown in FIG. 2, the lens connection surface 4c between the upper projection lens 4a and the lower projection lens 4b in the projection lens 4 is a flat surface, and the projection lens 4 itself, in other words, a strobe device. 1 is mounted inside the camera body 20, and only the upper projection lens 4a and the lower projection lens 4b are exposed to the outside through a slit-like hole 20a provided in the camera body 20.

このようにすることで、デジタル、アナログのコンパクトカメラのデザインの常套手段であった、ストロボ装置1がカメラ本体20の向かって右上方に必ず設けられているデザインと、大きく見栄えが変わるカメラ本体20の形状が得られるものとなる。また、必要最低限の部分のみを外部に露出すればよいものとなるので、装飾面でも簡素化が可能となり、コストダウンが図れるものとなる。   By doing so, the camera main body 20 is greatly changed in appearance from the design in which the strobe device 1 is always provided on the upper right side of the camera main body 20, which is a conventional means of designing digital and analog compact cameras. The shape is obtained. Further, since only the minimum necessary part needs to be exposed to the outside, it is possible to simplify the decorative surface and to reduce the cost.
