Abstract

PURPOSE:To facilitate assembling work of the entire part of a camera by building a focal plane shutter device which is unitized with a film winding mechanism, a frame number counter mechanism, and a focal plane shutter mechanism collectively into a camera body. CONSTITUTION:Front and rear curtain winding drums 16, 17 which wind up front and rear curtains cooperatively with a film winding mechanism and a toothless gear 25 formed with toothless parts 26a, 26b on part of the circumferential surface are provided. Front and rear curtain winding gears 23, 24 which are in one body with the drums 16, 17 are disposed around this gear 25, and the parts 26a, 26b of the gear 25 is constituted of the upper toothless part 26a having no teeth only in the upper part meshed with one of the gears 23, 24 and the lower toolthless part 26b having no teeth only in the lower part meshed with the other gear in continuation with this. The front curtain and the rear curtain are wound by the time difference of these two parts 26a, 26b.
