Claims (1)
時に通過した撮影レンズ系からの撮影光が結像する位置
に配置されている固定撮像素子と、 該反射鏡の上方であって、該反射鏡により反射した撮影
レンズ系からの撮影光が結像する位置に配置されている
焦点板と、 該焦点板に結像された像をファインダー窓に導くルーパ
と、 該ルーパの下方且つ該固体撮像素子の後方に配置されて
いる磁気ディスク及びその駆動機構部と、を備える磁気
記録式カメラにおいて、該反射鏡の上方に該撮像レンズ
系との合成焦点距離が長くなる様な凹レンズを配置して
撮影光の結像倍率を拡大させると共に結像位置を該反射
鏡から遠方に移動させて、その結像位置に焦点板を配置
し、 更に、結像位置が移動した分だけ焦点距離の短かくなっ
たルーパを配置して該焦点板に結像した像を更に拡大す
る様にしたことを特徴とする一眼レフファインダー。[Scope of Claim for Utility Model Registration] A photographic lens system, a reflector placed behind the photographic lens system, and a photographic lens system that is behind the reflector and passes through when the reflector is flipped up. a fixed image sensor disposed at a position where the photographing light from the camera forms an image; and a fixed image sensor disposed above the reflector at a position where the photographic light from the photographic lens system reflected by the reflector forms an image. a magnetic disk comprising: a focusing plate; a looper that guides the image formed on the focusing plate to a finder window; and a magnetic disk and its drive mechanism disposed below the looper and behind the solid-state image sensor. In a recording camera, a concave lens that increases the combined focal length with the imaging lens system is arranged above the reflector to increase the imaging magnification of the photographing light and move the image formation position farther from the reflector. A focus plate is placed at that image formation position, and a looper whose focal length is shortened by the movement of the image formation position is placed to further enlarge the image formed on the focus plate. A single-lens reflex finder featuring the following features.
