図3は、本実施の形態に係るカメラのフォーカスレンズ駆動機構を正面から視た図である。フォーカスダイヤル18は、カメラ2の上面に取付部32を介して回転可能に取り付けられている。また、フォーカスダイヤル18は接続ピン34を介して連結部材36の一方の端部に取り付けられている。また、カメラ2の上面における接続ピン34が貫通する部分には図示しない円弧状の貫通穴が設けられ、フォーカスダイヤル18の回転可能角度は貫通穴により規定される。なお、フォーカスダイヤル18の回転可能角度は360°未満であり、本実施の形態においては120°である。   FIG. 3 is a front view of the focus lens driving mechanism of the camera according to the present embodiment. The focus dial 18 is rotatably attached to the upper surface of the camera 2 via an attachment portion 32. Further, the focus dial 18 is attached to one end portion of the coupling member 36 via the connection pin 34. Further, an arc-shaped through hole (not shown) is provided in a portion through which the connection pin 34 penetrates on the upper surface of the camera 2, and the rotatable angle of the focus dial 18 is defined by the through hole. Note that the rotatable angle of the focus dial 18 is less than 360 °, and is 120 ° in the present embodiment.

図3における連結部材36のもう一方の端部には伝達部材40に設けられたピン38が取り付けられている。伝達部材40は、投影光学系42を構成するフォーカスレンズ42bを駆動するために設けられた略L字状に形成された部材であり、L字状を構成する腕40aと腕40bとの交差部分44においてカメラ2の筐体に回動可能に軸支されている。また、図3における腕40bの右端部には、略U字状の切欠部46が設けられ、切欠部46にはフォーカスレンズ42bに設けられたピン43が嵌挿されている。従って、切欠部46によりフォーカスレンズ42bの上下方向の移動が規制される。また、フォーカスレンズ42bはプロジェクタユニット48のケース内に配設されており、プロジェクタユニット48のケース内において上下方向に移動する。   A pin 38 provided on the transmission member 40 is attached to the other end of the connecting member 36 in FIG. The transmission member 40 is a substantially L-shaped member provided to drive the focus lens 42b constituting the projection optical system 42, and is an intersection of the arm 40a and the arm 40b constituting the L-shape. In 44, it is pivotally supported by the housing of the camera 2 so as to be rotatable. Further, a substantially U-shaped cutout 46 is provided at the right end of the arm 40b in FIG. 3, and a pin 43 provided on the focus lens 42b is fitted into the cutout 46. Accordingly, the vertical movement of the focus lens 42b is restricted by the notch 46. The focus lens 42 b is disposed in the case of the projector unit 48 and moves in the vertical direction in the case of the projector unit 48.

ここで、プロジェクタユニット48は、光源であるLED(発光ダイオード)50、LED50から射出された光を集光する集光レンズ52、投映画像を表示するLCOS(反射型液晶素子)54、入射した光をP偏光成分の光とS偏光成分の光とに分離するPBS(偏光ビームスプリッタ)56を備え、PBS56から図3における上方へ射出された光はフォーカスレンズ42bに入射する。また、フォーカスレンズ42bに入射した光はフォーカスレンズ42bの上方に設けられたズームレンズ42aを透過した後、不図示のミラーによって反射されプロジェクタ投映窓8からカメラ2の前方へ射出される。   Here, the projector unit 48 includes an LED (light emitting diode) 50 that is a light source, a condensing lens 52 that collects light emitted from the LED 50, an LCOS (reflection liquid crystal element) 54 that displays a projected image, and incident light. 3 is separated into P-polarized component light and S-polarized component light, and light emitted upward from the PBS 56 in FIG. 3 enters the focus lens 42b. The light incident on the focus lens 42b passes through the zoom lens 42a provided above the focus lens 42b, is reflected by a mirror (not shown), and is emitted from the projector projection window 8 to the front of the camera 2.

上述のように構成されるフォーカスレンズ駆動機構においては、図2において反時計回りにフォーカスダイヤル18が操作されると、図3において2点鎖線で示すように接続ピン34と共に連結部材36が右方向へ移動する。このとき、ピン38及び腕40aは鉛直方向に対して右側に傾き、腕40bの右端が下方へ移動する。従って、フォーカスレンズ42bは下方へ移動し、ピントがカメラ2に近い側に調節される。   In the focus lens driving mechanism configured as described above, when the focus dial 18 is operated counterclockwise in FIG. 2, the connecting member 36 is moved in the right direction together with the connecting pin 34 as shown by a two-dot chain line in FIG.

Accordingly, the focus lens 42b moves downward, and the focus is adjusted to the side close to the camera 2.

同様にして、図2おいて時計回りにフォーカスダイヤル18が操作されると、フォーカスレンズ42bは上方へ移動し、ピントがカメラ2から遠い側に調節される。   Similarly, when the focus dial 18 is operated clockwise in FIG. 2, the focus lens 42 b moves upward and the focus is adjusted to the side far from the camera 2.

本実施の形態に係るカメラによれば、プロジェクタボタンとフォーカスダイヤルとを一体として設けたため、投映に関する操作を行う際の操作性を優れたものとすることができる。また、撮影に関する操作を行う操作部と投映に関する操作を行う操作部とをユーザは直感的に判別することができる。   According to the camera of the present embodiment, since the projector button and the focus dial are provided integrally, the operability when performing operations related to projection can be improved. In addition, the user can intuitively distinguish between an operation unit that performs operations related to shooting and an operation unit that performs operations related to projection.

また、フォーカスダイヤルに溝を設け、また、フォーカスダイヤルの内部にばねを設けることにより、使用者がフォーカスダイヤルの回転操作を行う際の指掛かりを良好なものとし、ピントの微調節を行うことができると共にエルゴノミー性の向上を図ることができる。また、投映に関する操作部に指標を付したため、使用者が操作機能を容易に判別することができる。   In addition, by providing a groove in the focus dial and providing a spring inside the focus dial, the user can have a good finger grip when performing the rotation operation of the focus dial, and fine adjustment of the focus can be performed. In addition, it is possible to improve ergonomic properties. In addition, since an index is attached to the operation unit related to projection, the user can easily determine the operation function.

なお、上述の実施の形態において、投映指標22及びフォーカス指標24,26をLED等により構成して発光させるようにしてもよい。この場合においては、カメラ2の電源が入った状態で投映を行っていない場合には、投映指標22のみの発光を行う。また、プロジェクタボタン16の操作により投映の開始指示が行われると、フォーカス指標24,26の発光を開始する。従って、投映が行われている間は投映指標22及びフォーカス指標24,26の発光を行う。   In the above-described embodiment, the projection index 22 and the focus indices 24 and 26 may be configured by LEDs or the like to emit light. In this case, when projection is not performed with the camera 2 turned on, only the projection index 22 is emitted. Further, when an instruction to start projection is given by operating the projector button 16, the focus indicators 24 and 26 start to emit light. Accordingly, while the projection is being performed, the projection index 22 and the focus indices 24 and 26 are emitted.
