STROBOSCOPIC DEVICE CAPABLE OF INCLINING ORIENTATION DIRECTION TOWARD OPTICAL AXIS SIDE OF PHOTOGRAPHING LENS IN THE CASE OF MACRO PHOTOGRAPHING AND CAMERA

摘要

PROBLEM TO BE SOLVED: To transmit stroboscopic light to all the close photographing ranges in the case of macro photographing without using a separate member such as an exclusive flash by changing the relative positions of a reflector and a light source and inclining a light distribution direction from a light source toward the optical axis side of a photographing camera. ;SOLUTION: Aperture parts 3 having respectively curved shape are formed on both side walls of the reflector 1. The end part of an Xe tube 10 as a stroboscopic light source can move in parallel along the part 3. When the tube 10 is on a position 3a which is far from the front aperture part 4 of the reflector 1, a light distribution range is the smallest so as to be adequate to telephotographing. When the tube 10 is on a position 3c which is above a central line C in a vertical direction, the direction of a light beam (light distribution direction) on the central part of the light distribution range is inclined downward; so that the tube 10 is inclined to the optical axis side of the photographing lens existing in a lower side. The condition is suitable for the close-up photographing (macro photographing).;COPYRIGHT: (C)1998,JPO
