ABSTRACT:
The invention relates to a parallelepipedic tray intended to accommodate slides (7) which are to be viewed. The tray mainly comprises an upper wall (1) and a lower wall (2) each of which has grooves (6). The slides can be inserted in or removed from the tray via either of two open side surfaces, and to prevent the slides from dropping out when the tray is being handled, the tray has two flaps (8 and 9). Such a tray can be used on a slides viewer which has two carriages (22 and 23) to support and guide the trays, which carriages are disposed symmetrically on either side of optical system (28).
