PROBLEM TO BE SOLVED: To make an AF target mark and a short distance correction mark, etc., view and to facilitate operation by making information within a finder displayed on a field frame or a mask pressing plate peep from an ocular system. SOLUTION: A mask pressing plate 1 is attached to both pins 14 protrusively provided on a finder frame 13 in the state that the pins 14 pierce through holes provided at the opaque part of the plate 1. Thus, an screen size switching mask 16 is prevented from falling. The light of a finder image passes through an objective lens system 7 constituted of plural objective lenses, reaches a roof prism 8 and reaches the ocular system 10 through a prism 9 after its advancing direction is changed. Since an autofocus target mark and a short distance correction mark are printed and formed at the transparent part of the plate 1 through which the light is transmitted on the way to the prism 9 from the prism 8, the marks are viewed together with the finder image at the time of peeping the finder.
