PROBLEM TO BE SOLVED: To arrange a plurality of microprisms as closely as possible. SOLUTION: At an incidence hole of a pentagonal roof, a superimposition plate 32 is provided over a focus plate where a subject image obtained by a photography optical system is formed. A microprism group 52 is formed on the reverse surface of the superimposition plate 32. The microprism group 52 has a 1st prism array R1 and a 2nd prism array R2, which are arranged vertically by turns on a finder picture plane. The 1st prism array R1 is composed of a plurality of 1st microprisms 52a provided adjacently in the right-left direction of the finder picture plane. The 2nd prism array R2 has a 2nd microprism 52b. The 2nd microprism 52b is provided at a position corresponding to between two adjacent 1st microprisms 52a. COPYRIGHT: (C)2004,JPO&NCIPI |
