Traffic circle camera null for microfilm photographing

摘要

PURPOSE:To use space effectively and to secure a sufficiently long optical path by leading the image of an original on a rotating drum to a camera unit via a first mirror in the upper rear corner of a case and a second mirror in the bottom of the case. CONSTITUTION:The rotating drum 18 to carry the original with the original stuck on a rotating drum body by means of negative pressure is arranged sideways in the vicinity of the front plate 10a of the case 10 whose shape is almost a rectangular parallelopiped. A camera unit 24, constituted of lens 92, film 73, etc., is arranged at the rear of the top plate 10b of the case 10. The image of the original placed diagonally to the upper rear of the rotating drum 18 is led to the camera unit 24 via the first mirror 96 in the vicinity of the upper rear corner of the case and the second mirror 98 in the vicinity of the case bottom which is just beneath the camera unit 24, thereby photographing. Thus, a longer optical path is secured by effectively using the space of the long narrow case, and the device is miniaturized.
