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).
Claims6
A tray for storing and classifying slides, said tray comprising:
- parallel, plane, top and bottom members held in fixed relationship to each other,
- said parallel, plane, top and bottom members being provided with corresponding facing sets of transverse, slide-receiving grooves,
- said tray being symmetrical about a longitudinal plane passing through the mid points of both sets of grooves and having open left and right sides via which slides may be inserted in or removed from the tray, and
- two, symmetrically disposed, independently movable side flaps pivotably mounted on at least one of said top and bottom members,
- each side flap having a first, open position in which it allows slides to be inserted or removed via its side of the tray, and a second, closed position in which it prevents insertion or removal of slides.
A viewer for reading slides disposed in trays employed in storing and classifying slides, each of said trays comprising parallel, plane, top and bottom members held in fixed relationship to each other, said parallel, plane, top and bottom members being provided with corresponding facing sets of transverse, slide receiving grooves, each of said trays being symmetrical about a longitudinal plane passing through the midpoint of both sets of grooves and having open left and right sides via which said slides may be inserted or removed from the tray, and two symmetrically disposed, independently movable side flaps pivotably mounted to at least one of said top and bottom members, each side flap having a first, open position in which it allows slides to be inserted or removed via its side of the tray, and a second, closed position in which it prevents insertion or removal of said slides, said viewer including oprical means, two carriages, each of said carriages accommodating one tray, said carriages being mounted for movement in translation along two parallel paths disposed on either side of said optical means, said viewer further including means for removing the slides from the trays and for moving said slides horizontally past the optical means, from one tray to the other, together with means for moving the optical system vertically past the slide.
