Abstract

PURPOSE: To make possible the formation of information input in the absence of contact by generating photographing information digital signals from the change in the relative positions of light emitting elements and photodetectors.
CONSTITUTION: The light emitted from a lamp 24 provided to an aperture lever 5 or the like for controlling aperture is received in the photodetectors 271, 272W of a photodetecting system 27 opposing through holes 5c, whereby the photographing information corresponding to the aperture etc. is formed in the absence of contact. The information input device of a camera which generates information containing no noise etc. in high response without the effect of abrasion etc. is provided by this system which does not use any switch, brush, and the like.
