Abstract
A photographing number change-over device is effectively used for a four lens camera capable of simultaneously photographing four pictures on a film. The device comprises a first sector for shutting off two photographing lenses symmetrically opposed with respect to a center axis of the film, a second for shutting off either one of two remaining photographing lenses, and a driving member rotatively driven in increments of 90.degree. by a motor through a reduction gear, a cam, a reciprocal moving member, a bell crank lever and an engaging pawl for driving the first and second sectors to positions where all the photographing lenses are not shut off. The device further comprises regulating pins which are engageable and stopping the first and second sectors at positions where the photographing lenses are shut off, and an annular change-over member for changing over the regulating pins to a first position where the regulating pins engage and stop both the first and second sectors, a second position where the regulating pins engage and stop only the first sector, and a third position where the regulating pins engage and stop neither the first sector nor the second sector. With this arrangement, required picture number photographing is always effected even if the photographing number is changed under any conditions.
