ABSTRACT:
A low-cost compact slide presentation toy offering combined slide projector and viewer function by integrating a slide projector section and a slide viewer section with a single housing. Both sections share a common slide recieving slot so that simulataneous viewing and projecting is made possible by means of a novel rotatable slide member which carries a plurality of image cells in a diametrically opposite manner. Also, images to be viewed or projected can be changed by simply rotating a slide member without the need of actually removing a slide from the device. This device is particular attractive for young children.
