Abstract
PURPOSE:To make the title camera small in size and light in weight by equipping a concave mirror which folds and reflects an incident luminous flux parallel with an optical axis direction from an object at a certain angle with respect to the incident direction of the incident luminous flux. CONSTITUTION:The photographing optical system for the camera is constituted of the concave mirror 10 which folds and reflects the incident luminous flux parallel with the optical axis direction from the object at a certain angle thetawith respect to the incident direction of the incident luminous flux and a reflecting mirror 12 which guides the incident luminous flux from said concave mirror to an image-formation surface by reflecting the luminous flux. Therefore the incident luminous flux from the object is folded and reflected by the concave mirror and also condensed, and the condensed incident luminous flux is reflected by the reflecting mirror and guided to the image-formation surface to form an image. Thus, the optical path can be shortened by the thickness of a lens as compared with a camera which bends at least backfocus reflecting mirrors and reduction in size and weight can be attained since the lens is not used.
