Description

【0001】
【発明の属する技術分野】
本発明はカメラのストロボ等の照明装置に関するものである。
【0002】
【従来の技術】
近年では、使い勝手の良さから自動発光ストロボを内蔵したカメラが一般化している。ストロボ発光部は、発光管としての細長い円柱状のXe(キセノン)管と、Xe管から被写体側とは反対側に発光した光線を被写体側に反射させるためにXe管の背面側を覆う反射笠とXe管から発光した光を撮影画角に対応した照射範囲に効率良く導光するための光学部材を有して構成されている。反射笠は、表面が鏡面処理されたAl(アルミ)の板材が使用されている。Xe管は円柱状のガラス管の中にXeガスを満たして作られ、ガラス管の両端にはプラスとマイナスの端子が形成されている。Xe管のガラス表面には、両極近傍を除いた中央部に透明の導電性のコーティングが施されており、このコーティングはトリガ電極として用いられる。
【0003】
Xe管を発光させるには、Xe管の両端に約280〜330Vに充電された主コンデンサを接続するとともに、トリガ電極に数kVのパルス電圧をかけてXe管内部のXeガスを励起させ、主コンデンサの充電エネルギーをXe管を介して放電させて光エネルギーに変換させる。
【0004】
トリガ電圧を印加する手段としては、反射笠を金属部材(アルミ)で作り、反射笠とXe管のトリガ電極部を接触させて反射笠に直接トリガ電圧を印加する手法が多用されている。この場合、反射笠とトリガ電極とが確実に接触していないと、トリガ電圧を印加してもXeガスが励起せず、Xe管が発光しない。従って、Xe管を確実に発光させるためには、反射笠とトリガ電極との接触状態が重要になり、具体的には、反射笠とトリガ電極部の接触抵抗が数KΩ以下である必要がある。このとき、光学部材は撮影者等が誤ってXe管や反射笠に触れないようにプロテクタの役割もしている。
【0005】
このため、従来のストロボ装置では、トリガ電極部を有するXe管を反射笠に押し当てるように押圧力を付与するようにしている。押圧力としては、例えば実公昭61−18502号公報に開示されているように、円形状あるいは円弧状の弾性体よりなるブッシングの一方を反射笠の側面部分に当てて、その弾性力を利用してXe管を反射笠に押し当てるものもある。
【0006】
また、実公昭61−18503号公報に開示されているように、両端に穴のあいた帯状の弾性部材をXe管の両端に引っかけて反射笠の裏側を通し、弾性部材の弾性力によってXe管を反射笠に引き寄せるものもある。
【0007】
【発明が解決しようとする課題】
ところで、近年開発されている光学部材にライトガイド光学系を用いたストロボ装置は、側面反射笠を必要としない。そのために上述の従来例の実公昭61−18502号公報に開示されているように側面反射笠に弾性体よりなるブッシングの一方を反射笠の側面部分に当てることは不可能である。
【0008】
また、カメラの小型化に伴ってストロボ装置も小型化が要求されている。したがって、上述の従来例の実公昭61−18503号公報に開示されているように弾性部材をXe管の両端に引っかけて反射笠の裏側を通すと、その弾性体の分だけ奥行き方向が伸びてしまい、装置の大型化を招くことになる。
【0009】
また、カメラ等の携帯機器にストロボ装置を組み込む時にはストロボ装置をユニット化しておいて欲しいという要望がある。
【0010】
本発明は上記従来技術の問題点を考慮してなされたもので、小型で、なおかつ、携帯機器に組み込み易いストロボ装置を提供することを目的とする。
【0011】

【0013】
また、前記目的を達成するために本願における請求項3記載の発明によれば、請求項1または2記載の照明装置において、上記弾性部材は上記発光管の端部に一体的に配置されることを特徴とする。

【0016】
さらに、ストロボ装置を小型化したので、本発明が搭載されるカメラ全体も小型化を図ることが可能となる。
【0017】
【発明の実施の形態】
以下本発明の実施の形態を図面を参照しながら説明する。
【0018】
図1は本発明の照明装置をカメラ本体1の上辺部に設けたときの実施形態の要部概略図、図2は本発明の照明装置(ストロボ装置)の分解斜視図、図3は本発明の照明装置の斜視図、図4は本発明の照明装置の上面から見た図を示している。図5は本発明の照明装置の正面から見た図を示している。図6は本発明の照明装置の側面から見た図を示している。図中、1はカメラ本体、2はレンズ鏡筒部であり、撮影レンズを保持している。3はファインダである。4は照明装置であり、カメラ本体1の右上部に設けている。
【0019】
図2において、5は被写体に光を発する発光管(Xe管)であり、このXe管5の両端にはプラス電極5aとマイナス電極5bとが形成されている。プラス電極5aおよびマイナス電極5bにはそれぞれ不図示のリード線が接続されている。
【0020】
6は円形状のゴム等の弾性部材よりなるブッシングであり、Xe管5の発光した光を遮らない位置までそれぞれ挿入される。
【0021】
7はXe管5からの放射光束のうち前方以外の、例えば後方(被写体側と反対方向に発する光を被写体側に反射させるための反射笠であり、集光反射する一次元方向に曲率を有し、表面が鏡面処理されたAl(アルミ)の板材により形成されている。Xe管5の表面には両端部近傍を除いて、導電性コーティング(不図示)が施されている。導電コーティングと反射笠7とが接触しているので、反射笠7がXe管5のトリガ電極になる。反射笠7には、トリガ電極である反射笠7にトリガ電圧を印加するためのリード線(不図示)を接続するための接続部7aがある。
【0022】
8はXe管5から直接入射した光束及び反射笠7で反射して入射した光束を所定形状の光束として集光し、被写体側へ撮影に必要な画角に効率良く照射する照明光束導光用の光学部材(ライトガイド)であり、アクリル等の透明樹脂またはガラスより形成される。
【0023】
ここで、上記光学部材(ライトガイド)を用いたストロボ装置は、一般的に発光管(Xe管)とライトガイドを近接させることにより、効率をほとんど落とすことなく小型化が図れるため、発光管の発する熱の影響を受けない程度離すだけの設定をしていることが多い。したがって、ライトガイドと発光管の空気間隔は極めて小さいことになる。
【0024】
9はストロボ発光部を保持するストロボ筐体(装置筐体)であり、非導電性の樹脂により形成されている。ストロボ筐体9の上下には孔部9aが形成されている。
【0025】

【0027】
このとき、弾性部材よりなるブッシング6と一体的に構成されるXe管5は、ライトガイド8とXe管5の空気間隔が小さいことから、弾性部材よりなるブッシング6の大きさを大きくする必要がなく、ストロボ筐体9の後方にはみ出すことなく、ライトガイド8がストロボ筐体9にパッチン嵌合する際にライトガイド8により弾性部材よりなるブッシング6が押圧され、Xe管5は反射笠7に押し当てられる。こうして、ストロボ装置の奥行きを大きくすることなしに、Xe管5を反射笠7に確実に密着することができ、Xe管5は確実に発光することができる。
【0028】
ここで、本発明は、ストロボ筐体9にライトガイド8がパッチン嵌合するするために孔部を有する照明装置を用いて説明したが、本発明はこれに限定されるものではなく、ストロボ筐体9にライトガイド8がパッチン嵌合するするために凹部を設けても構わない。
【0029】
また、本発明は、弾性部材よりなるブッシング6はXe管5に一体的に取り付けられている照明装置を用いて説明したが、本発明はこれに限定されるものではなく、ライトガイド8に一体的に取り付けられていても構わない。
【0030】
【発明の効果】
以上説明したように、本発明によれば、ストロボ筐体に反射笠とXe管が所定の位置に配置し、光学部材とXe管の間に弾性部材を配置し、光学部材をストロボ筐体に押し込み、パッチン嵌合で固定するようにしたので、反射笠にXe管を確実に当接することができるとともに、ストロボ装置を小型化することができた。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lighting device such as a camera strobe.
[0002]
[Prior art]
In recent years, cameras with built-in automatic flashes have become popular due to their ease of use. The stroboscopic light emitting section includes an elongated cylindrical Xe (xenon) tube as an arc tube, and a reflection shade covering the back side of the Xe tube to reflect light emitted from the Xe tube to the side opposite to the object side to the object side. And an optical member for efficiently guiding the light emitted from the Xe tube to the irradiation range corresponding to the angle of view. The reflector is made of an Al (aluminum) plate whose surface is mirror-finished. The Xe tube is made by filling a cylindrical glass tube with Xe gas, and plus and minus terminals are formed at both ends of the glass tube. The glass surface of the Xe tube is provided with a transparent conductive coating at the center except for the vicinity of both poles, and this coating is used as a trigger electrode.
[0003]
In order to cause the Xe tube to emit light, a main capacitor charged to about 280 to 330 V is connected to both ends of the Xe tube, and a pulse voltage of several kV is applied to the trigger electrode to excite the Xe gas inside the Xe tube. The charge energy of the capacitor is discharged through the Xe tube and converted into light energy.
[0004]
As a means for applying a trigger voltage, a method of forming a reflection shade from a metal member (aluminum), and applying a trigger voltage directly to the reflection shade by bringing the reflection shade into contact with a trigger electrode portion of the Xe tube is often used. In this case, if the reflection shade and the trigger electrode are not securely in contact with each other, the Xe gas is not excited even when the trigger voltage is applied, and the Xe tube does not emit light. Therefore, in order to ensure that the Xe tube emits light, the contact state between the reflector and the trigger electrode is important. Specifically, the contact resistance between the reflector and the trigger electrode must be several KΩ or less. . At this time, the optical member also serves as a protector so that a photographer or the like does not accidentally touch the Xe tube or the reflection shade.
[0005]
For this reason, in the conventional strobe device, a pressing force is applied so as to press the Xe tube having the trigger electrode portion against the reflector. As the pressing force, as disclosed in, for example, Japanese Utility Model Publication No. 61-18502, one of a bushing made of a circular or arcuate elastic body is applied to the side surface portion of the reflector, and the elastic force is used. In some cases, the Xe tube is pressed against the reflector.
[0006]
Further, as disclosed in Japanese Utility Model Publication No. 61-18503, a band-shaped elastic member having holes at both ends is hooked to both ends of the Xe tube, and passes through the back side of the reflecting shade, and the elastic force of the elastic member causes the Xe tube to pass through. Some are drawn to the reflective shade.
[0007]
[Problems to be solved by the invention]
By the way, a recently developed strobe device using a light guide optical system for an optical member does not require a side reflector. Therefore, as disclosed in the above-mentioned conventional example of Japanese Utility Model Publication No. 61-18502, it is impossible to apply one of the bushings made of an elastic body to the side reflectors to the side portions of the reflectors.
[0008]
In addition, with the miniaturization of cameras, miniaturization of strobe devices is also required. Therefore, when the elastic member is hooked on both ends of the Xe tube and passed through the back side of the reflection shade as disclosed in the above-mentioned conventional example of Japanese Utility Model Publication No. 61-18503, the depth direction is extended by the amount of the elastic body. This leads to an increase in the size of the device.
[0009]
Further, there is a demand that the strobe device be unitized when the strobe device is incorporated into a portable device such as a camera.
[0010]
SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-described problems of the related art, and has as its object to provide a small-sized strobe device which can be easily incorporated into a portable device.

[0013]

[0015]
As described above, according to the present invention, the reflector and the Xe tube are arranged at predetermined positions in the strobe housing, the elastic member is arranged between the optical member and the Xe tube, and the optical member is pushed into the strobe housing. Since the Xe tube is fixed by the patch fitting, the Xe tube can be reliably brought into contact with the reflector and the strobe device can be downsized.
[0016]
Further, since the size of the strobe device is reduced, the size of the entire camera on which the present invention is mounted can be reduced.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0018]
FIG. 1 is a schematic view of a main part of an embodiment in which an illumination device of the present invention is provided on an upper side of a camera body 1, FIG. 2 is an exploded perspective view of an illumination device (strobe device) of the present invention, and FIG. FIG. 4 is a perspective view of the lighting device of FIG. FIG. 5 shows a front view of the lighting device of the present invention. FIG. 6 shows a view from the side of the lighting device of the present invention. In FIG. 1, reference numeral 1 denotes a camera body, and 2 denotes a lens barrel, which holds a taking lens. Reference numeral 3 denotes a finder. Reference numeral 4 denotes an illumination device, which is provided at an upper right portion of the camera body 1.
[0019]
In FIG. 2, reference numeral 5 denotes an arc tube (Xe tube) for emitting light to a subject, and a plus electrode 5a and a minus electrode 5b are formed at both ends of the Xe tube 5. Lead wires (not shown) are connected to the positive electrode 5a and the negative electrode 5b, respectively.
[0020]
Reference numeral 6 denotes a bushing made of an elastic member such as a circular rubber, which is inserted to a position where the light emitted from the Xe tube 5 is not blocked.
[0021]
Reference numeral 7 denotes a reflection shade for reflecting light emitted from the Xe tube 5 other than the front, for example, rearward (light emitted in the direction opposite to the object side) to the object side, and has a curvature in a one-dimensional direction in which light is condensed and reflected. The surface of the Xe tube 5 is coated with a conductive coating (not shown) except for near both ends. Since the reflection shade 7 is in contact with the reflection shade 7, the reflection shade 7 becomes a trigger electrode of the Xe tube 5. The reflection shade 7 has a lead wire (not shown) for applying a trigger voltage to the reflection shade 7 serving as a trigger electrode. ) Is provided.
[0022]
Reference numeral 8 denotes an illumination light guide for condensing a light beam directly incident from the Xe tube 5 and a light beam reflected by the reflection shade 7 as a light beam having a predetermined shape and efficiently irradiating the object side with an angle of view required for photographing. The optical member (light guide) is made of a transparent resin such as acrylic or glass.
[0023]
Here, a strobe device using the above-mentioned optical member (light guide) can be miniaturized with almost no reduction in efficiency by bringing the light emitting tube (Xe tube) and the light guide close to each other. In many cases, the distance is set so that it is not affected by the heat generated. Therefore, the air gap between the light guide and the arc tube is extremely small.
[0024]
Reference numeral 9 denotes a strobe housing (device housing) for holding a strobe light emitting unit, which is formed of a non-conductive resin. Holes 9a are formed in the upper and lower portions of the strobe housing 9, respectively.
[0025]
The light guide 8 is integrally formed with a patch claw (engaging claw) 8a for fixing the light guide 8 to the flash housing 9.
[0026]
In FIG. 3, in a lighting device 4, an Xe tube 5 integrated with a reflection shade 7 and a bushing 6 made of an elastic member is arranged at a predetermined position in a strobe housing 9, and a light guide 8 is pushed into the strobe housing 9. Then, the patch claw 8a of the light guide 8 is fixed to the hole 9a of the strobe housing 9 by patch fitting (collet chuck type clamp fitting using spring force).
[0027]
At this time, in the Xe tube 5 integrally formed with the bushing 6 made of the elastic member, since the air gap between the light guide 8 and the Xe tube 5 is small, it is necessary to increase the size of the bushing 6 made of the elastic member. The bushing 6 made of an elastic member is pressed by the light guide 8 when the light guide 8 is fitted into the strobe housing 9 without being protruded from the rear of the strobe housing 9. It is pressed. Thus, the Xe tube 5 can be securely brought into close contact with the reflection shade 7 without increasing the depth of the strobe device, and the Xe tube 5 can reliably emit light.
[0028]
Here, the present invention has been described using an illuminating device having a hole for fitting the light guide 8 to the strobe housing 9 in a patch-fit manner. However, the present invention is not limited to this. A concave portion may be provided for the light guide 8 to be fitted into the body 9 in a patch-fit manner.
[0029]
In the present invention, the bushing 6 made of an elastic member has been described using an illumination device integrally attached to the Xe tube 5, but the present invention is not limited to this. It may be attached to it.
[0030]
【The invention's effect】
As described above, according to the present invention, the reflector and the Xe tube are arranged at predetermined positions in the strobe housing, the elastic member is arranged between the optical member and the Xe tube, and the optical member is mounted on the strobe housing. Since the Xe tube is fixed by pushing in and fitting with a patch, the Xe tube can be reliably brought into contact with the reflector and the strobe device can be downsized.
[0031]
Further, since the size of the strobe device is reduced, the size of the entire camera on which the present invention is mounted can be reduced.
