たものである請求項１記載のカメラ用光投射装置
。 (3) 上記拡散手段は上記光源の光を拡散させる
特性を有する反射面を持つた部材を含んだもので
ある請求項１記載のカメラ用光投射装置。[Claims for Utility Model Registration] (1) A light source, a focusing optical system provided corresponding to the light source, and a light emitted from the light source entering the focusing optical system from a direction different from the direct incident light from the light source. It is characterized by comprising a light diffusing means for guiding the light so that the light is incident, so that the light emitted from the focusing optical system can be used as an auxiliary light for automatic focusing or distance measurement and a light for displaying a self-timer operation. Light projection device for cameras. (2) The light projection device for a camera according to claim 1, wherein the light diffusing means includes a block material having diffused transmittance provided around the light emitting portion of the light source. (3) The light projection device for a camera according to claim 1, wherein the diffusion means includes a member having a reflective surface having a property of diffusing the light from the light source.
