    • The object of the present invention is to enable reliable supply of oxygen which is necessary for a fuel cell to generate electric power, to the fuel cell. In a camera, air orifices for linking the space inside a cell compartment with the outside of a casing are disposed in a position other than the portion (grip portion) which is held by a user, in the vicinity of the center of the front surface of the casing, that is, in the vicinity of a lens-barrel, and a concave-convex portion serving as an air orifice guard is formed at the side opposite to that where the lens-barrel is disposed with respect to the air orifices. As a result, even when the user takes a picture of an object by holding the camera with his/her own hand, the air orifices are prevented from being closed by the user's hand, oxygen (air) can be constantly supplied to the fuel cell accommodated inside the cell compartment, and the fuel cell can continuously generate a sufficient quantity of electricity. The present invention can be employed in a camera.
    • 本发明的目的是使燃料电池能够可靠地供应燃料电池产生电力所需的氧气。 在相机中,将用于将细胞室内的空间与壳体的外部连接的空气孔设置在除了由使用者握持的部分(握持部分)之外的位置,在前表面的中心附近 在镜筒附近形成有作为空气孔护罩的凹凸部,与透镜筒相对于空气孔相对的一侧形成。 结果,即使当用户通过用自己的手握住相机来拍摄对象的图片时,防止用户的手闭合空气孔,可以将氧气(空气)不断地供应到燃料电池 容纳在电池室内,并且燃料电池可以连续地产生足够的电量。 本发明可以用在相机中。
