ABSTRACT:
A housing has a front with a window therein. A shock mounting device in the housing is affixed to the bottom thereof. A projector support device extends from the shock mounting device. A securing device releasably secures the slide projector to the projector support device in a manner whereby the slide projector is selectively adjustable in position relative to the bottom of the housing and light transmitted from the slide projector is transmitted through the window. Electrical conductors extend through the housing and are electrically connected to the slide projector for supplying electrical energy for energizing the projector. A screen spaced from the front of the housing receives light transmitted from the slide projector and presents an enlarged reproduction of an image on a slide in the slide tray of the slide projector.
