A state occurs in which the subject 71 cannot be brightly illuminated by being blocked by the lens covering cylinder 62, and as a result, as shown in FIG. 8, the shadow image 62 a of the lens covering cylinder 62 is included in the captured image 81 of the subject 71. As a result, there is a problem that a high-quality captured image 81 cannot be obtained. In FIG. 6, θ is the strobe light irradiation angle of the built-in strobe.

特許文献1には、ストロボ内蔵カメラを収容する防水ケースに対して、内蔵したストロボからの光を近接撮影用レンズの前方近傍位置までガイドする光ガイド手段を着脱可能に備えた水中撮影用アダプタが提案されている。   Patent Document 1 discloses an underwater shooting adapter that includes a light guide unit that detachably guides light from a built-in strobe to a position near the front of a close-up lens for a waterproof case that houses a camera with a built-in strobe. Proposed.

この特許文献1の場合、近接撮影用レンズの前方近傍位置までストロボからの光をガイドし得るものの、内蔵したストロボからの光の被写体に対する照射範囲を調節することまでは考慮されていない。

To a range extending over the upper position of the case shoe portion 25.

図4に示すように、前記バウンスプレート11をケースシュー部25の上方位置に回動変位した際には、このバウンスプレート11は、内蔵ストロボ33のストロボ光照射角θの範囲外となり、近接撮影以外の撮影時におけるストロボ光に影響を与えることは皆無となる。   As shown in FIG. 4, when the bounce plate 11 is rotated and displaced to a position above the case shoe portion 25, the bounce plate 11 is out of the range of the strobe light irradiation angle θ of the built-in strobe 33, and close-up photography is performed. There will be no effect on the strobe light during shooting.

また、前記バウンスプレート11をレンズ被覆筒部23の前方位置に臨ませた状態では、前記バウンスプレート11のレンズ被覆筒部23に臨む面に設けた白色又は銀色等に色付けした反射面11cにより前記透過窓24を透過する内蔵ストロボ33のストロボ光を上から下へ向けて反射し、これにより、被写体10に対する照射領域を変更し得るように構成している。   In the state where the bounce plate 11 faces the front position of the lens covering cylinder portion 23, the bounce plate 11 is reflected by the reflecting surface 11c colored in white or silver or the like provided on the surface facing the lens covering cylinder portion 23 of the bounce plate 11. The strobe light of the built-in strobe 33 that passes through the transmission window 24 is reflected from the top to the bottom, so that the irradiation area on the subject 10 can be changed.

次に、本実施例に係る近距離撮影用バウンスアダプタ1を使用した被写体10に対する近接撮影動作について、図2、図3をも参照して説明する。
図2に示すように、内蔵ストロボ33を有する前記カメラ31をカメラ用水中ケース21内に収納し、この状態で水中にて内蔵ストロボ33を発光させ被写体10の近接撮影を行う。このとき、前記前記近距離撮影用バウンスアダプタ1におけるバウンスプレート11の位置は、図2に示すように、レンズ被覆筒部23の前方上方位置で、かつ、ストロボ光照射角θの範囲内とする。
Next, a close-up shooting operation for the subject 10 using the short-distance shooting bounce adapter 1 according to the present embodiment will be described with reference to FIGS.
As shown in FIG. 2, the camera 31 having the built-in strobe 33 is housed in a camera underwater case 21, and in this state, the built-in strobe 33 emits light to perform close-up shooting of the subject 10. At this time, as shown in FIG. 2, the position of the bounce plate 11 in the bounce adapter 1 for short-distance shooting is located at the upper front position of the lens-covered cylinder portion 23 and within the range of the strobe light irradiation angle θ. .

このようなバウンスプレート11の配置により、内蔵ストロボ33からのストロボ光の一部は前記反射面11cにより下方に向けて反射され、この結果、レンズ被覆筒部23により遮られる内蔵ストロボ33からの直接光が届かない被写体10の表面を反射光により明るく照射し、前記レンズ被覆筒部23による影を生じさせない状態となる。   Due to the arrangement of the bounce plate 11, a part of the strobe light from the built-in strobe 33 is reflected downward by the reflecting surface 11 c, and as a result, directly from the built-in strobe 33 that is blocked by the lens covering cylinder portion 23. The surface of the subject 10 that does not reach light is illuminated brightly by the reflected light, and no shadow is caused by the lens-covered cylinder portion 23.

このような本実施例の態様での近接撮影の実行によって、図3に示すように、前記被写体10の撮影画像10Aは、その表面にレンズ被覆筒部23の影部分が表出しない良好な画質を有するものとなる。尚、図3中、10Bは被写体10の底部に生じる影像である。   By performing close-up photography in this aspect of the present embodiment, as shown in FIG. 3, the photographed image 10A of the subject 10 has a good image quality in which the shadow portion of the lens covering cylinder portion 23 does not appear on the surface. It will have. In FIG. 3, reference numeral 10 </ b> B denotes a shadow image generated at the bottom of the subject 10.

また、前記操作円盤13を回動操作してバウンスプレート11のレンズ被覆筒部23の前方での回動位置を種々変更することもでき、近接撮影時の被写体10の前記レンズ被覆筒部23の突出端面からの位置の相違にも対応できる。   In addition, the operation disk 13 can be rotated to change various rotation positions of the bounce plate 11 in front of the lens-covered tube portion 23, and the lens-covered tube portion 23 of the subject 10 during close-up photography can be changed. It is possible to cope with the difference in position from the protruding end face.

さらに、前記バウンスプレート11の形を突出端11b側が大寸法の台形状としているので、ストロボ光照射角θに応じたストロボ光の広がりに対応してこのストロボ光を下方に反射でき、形状が種々に相違する被写体10の近接撮影にも広範に対応することができる。   Further, since the shape of the bounce plate 11 has a large trapezoidal shape on the protruding end 11b side, the strobe light can be reflected downward corresponding to the spread of the strobe light according to the strobe light irradiation angle θ, and various shapes are available. It is possible to deal with a wide range of close-up shooting of the subject 10 that is different from the above.

次に、図5、図6を参照して本実施例に係る近距離撮影用バウンスアダプタ1の変形例にいて説明する。   Next, a modified example of the bounce adapter 1 for short-distance shooting according to the present embodiment will be described with reference to FIGS.

図5、図6は変形例の近距離撮影用バウンスアダプタ1Aを示すものであり、この近距離撮影用バウンスアダプタ1Aは、既述した場合と同様な当接基体3、ガイド胴部4、没入体5及びプレート支持体6を備えるとともに、前記プレート支持体6に取り付けた前記カメラ31の対物レンズの光軸と同方向に沿う配置の第1軸支部41と、この第1軸支部41により回動可能に支持された前記カメラ用水中ケース21の幅方向に沿う配置の第2軸支部42とを具備する取付基部2Aと、この取付基部2Aにより支持された上述した場合と同様なバウンスプレート11とを有している。   5 and 6 show a modified bounce adapter 1A for short-distance shooting. This bounce adapter 1A for short-distance shooting has the same contact base 3, guide body 4, and immersion as in the case described above. A first shaft support portion 41 arranged along the same direction as the optical axis of the objective lens of the camera 31 attached to the plate support body 6 and rotated by the first shaft support portion 41. A mounting base portion 2A having a second shaft support portion 42 arranged along the width direction of the camera underwater case 21 movably supported, and a bounce plate 11 similar to that described above supported by the mounting base portion 2A. And have.

すなわち、変形例の近距離撮影用バウンスアダプタ1Aのバウンスプレート11は、前記回動連結体12を介してその基端11a側が第2軸支部42により上下方向に回動可能に支持され、突出端11b側が前記レンズ被覆筒部23の前方位置からケースシュー部25の上方位置に亘る範囲に変位するとともに、第2軸支部42とともに前記第1軸支部41により回動支持されてその軸線の回りを回動変位し、前記レンズ被覆筒部23に臨む面に設けた反射面11cにより前記透過窓24を透過する内蔵ストロボ33からのストロボ光を上から下へ向けて又は図6に示すように斜下方へ反射して、前記被写体10に対する照射領域を多様に変更し得るように構成している。   That is, the bounce plate 11 of the short-distance shooting bounce adapter 1A of the modified example is supported by the second shaft support portion 42 so that the base end 11a side can be pivoted in the vertical direction via the pivot coupling body 12, and the projecting end. 11b is displaced in a range extending from the front position of the lens covering cylinder portion 23 to the upper position of the case shoe portion 25, and is supported by the first shaft support portion 41 together with the second shaft support portion 42 so as to rotate around the axis.
