<p>A circular slide tray in which the guide walls defining the slide receiving slots terminate spaced from the hub to provide close packing of adjacent slides at the hub. The guide walls are recessed at one face of the tray, the recess being beveled progressing radially and axially inward of the tray to provide proper alignment of the slide receiving slots with a slide projector by the normal slide pusher bar. And, a slide retaining strip extends around the hub and has straight fibers extending radially therefrom to guide and retain the edges of the slides adjacent the hub to maintain the slides in proper alignment.</p> |
