Abstract

PURPOSE:To improve fitting precision while preventing a focal plane fitting member from breaking owing to erroneous operation by uniting a focal plane and the focal- plane fitting member in one body and by making it possible to attach and detach the body to and from a camera body. CONSTITUTION:On the flank of focal plane fitting member 1, projections 1' and 1'' are provided, and the projections at the side edge part of focal plane 2 are inserted into the flank groove part of fitting member 1 and united by being activated upward by spring 3. Unit 5 made in one body has projection part 1' of its fitting member 1 engaged in receiving opening 7' provided in receiving plate 7, and consequently the reverse surface of pentaprism frame 6 is by spring 3 pressed against the top surface of focal plane 2, so that the focal plane becomes a fixed position.
