发明名称 PHOTOGRAPHIC SLIDE PROJECTORS
摘要 A photographic slide projector wherein a slide-changer is adapted to shift slides successively from a magazine to a projecting position and then back to the magazine. When each slide is in the projecting position it is held by a slide-holder, and this holder is supported for swinging movement by the housing of the projector. In this way, when the slide-holder is swung outwardly it is accessible to manually receive a slide which then can be manually removed therefrom. On the other hand, the slide-holder can remain in an operative position where it will receive a slide from the slide-changer and return a slide thereto.
