    • A reflection-type overhead projector for projecting large transparencies onto a remote screen. The overhead projector has a base with a Fresnel mirror that serves as a stage on which a transparency to be projected is placed, and a lamp housing for a projection lens with an associated mirror which is supported on a pivotable arm above the base. The lamp housing is formed with an opening for allowing the passage of light to illuminate the transparency on the stage. This opening is fitted with a protective screen for guarding the fingers from the heated illumination lamp.
    • 一种用于将大型透明胶片投影到远程屏幕上的反射型高架投影仪。 高架投影仪具有带有菲涅耳镜的底座,其作为放置透明体的台阶,以及具有支撑在基座上方的可枢转臂上的相关反射镜的投影透镜的灯壳体。 灯壳形成有用于允许光通过以照亮台上的透明度的开口。 这个开口配有一个保护屏,用于保护手指不受加热的照明灯的影响。
