Document Type and Number:

Japanese Patent JP3670402

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To make the surroundings of a finder compact.
SOLUTION: A visual field switching plate 20 provided with a panoramicsized visual field aperture 33 and a C-sized visual field aperture is installed so as to be freely rotated around a photographing optical axis 18a. The center of the panoramic visual field aperture 33 and the center of the C-sized visual field aperture are arranged on the circumference passing through the center of an H-sized visual field aperture 27 with the photographic optical axis 18a as the center. The visual field switching plate 20 is retreated on the circumference passing through the center of the finder optical axis, so that the horizontal size can be made smaller than that of a conventional finder device. A toggle spring 40 for selectively switching the energizing direction of the visual field switching plate 29 taking the position of the plate 29 with the C-sized visual field frame 34 set on the H-sized visual field aperture 27 as the boundary, is installed on the plate 29.
