The stack loader (9) has a movable receiving member (31) with two slide compartments (35 and 36), wherein the receiving member serves as a movable intermediate tray whose slide compartments can be selectively aligned with the opening of the chute (37) and can be selectively loaded and unloaded again with an end slide (21, 24) of the stack of slides in one of the storage chambers (17 or 19) by a series of friction wheels (47, 49, 61, 63).

Abstract: A slide receptacle comprised of a bin (8) and hopper (11) for receiving the bin. The bin is of substantially parallelepipedic shape, having an upper end, a lower end opposite the upper end, and four sidewalls. A pair of stop means including outwardly protruding tines (26, 28) are located on first and second opposing sidewalls at the lower end. Each of the stop means includes inwardly protruding tabs (22, 24) for partially closing the lower end, such that slides in the bin are prevented from dropping out of the lower end. The stop means are flexible such that pressure on tines (26, 28) causes tabs (22, 24) to open to allow slides to pass through the lower end. The hopper (40) has four inner walls, the dimensions of which conform to the outer dimensions of the bin. Two opposing inner walls (44, 46) are provided with grooves (48, 50, 52, 54), a bottom portion (70) of each groove bending outwardly.

Abstract: A computer-controlled slide previewer, sorter, projector tray loader and archiving system. Slides are held in a stack in a hopper in a known sequence. A slide release mechanism is provided to deliver one slide from the stack of slides to a position over one of a plurality of sorting bins or compartments of a projector tray. An accession number is derived for each slide either from a number read from a label affixed to the slide or from the relative position of the slide in the hopper. This accession number is transmitted to a sorting logic. In accordance with a sort algorithm using the accession number, the sorting logic positions the appropriate bin or compartment to receive the slide. The sorting logic then activates the release mechanism to deliver the slide into the bin or compartment positioned to receive the slide.

Abstract: A loading and indexing mechanism for loading articles into successive compartments in a circular tray is shown. It is particularly adapted for use with slide transparencies and their circular trays. The mechanism uses a pawl and gear arrangement to catch and hold successive compartments of a tray in registration with the insertion station. Cams are used to cause turning of the axle on which the tray is mounted and engagement and disengagement of the pawl and gear in coordination with each insertion operation.

Abstract: A slide previewer/sorter/stack loader having a holder (18) which is adapted to receive two photographic slides in first and second receptacles at one end thereof. The holder is initially positioned at an angle above horizontal so that a first slide placed on a chute (16, 17) will drop into the first receptacle by force of gravity. When in the initial position, the slide in the holder is illuminated by a back light so that the slide can be previewed through a window in the holder and edited. The holder pivots in such a manner that the second receptacle can be positioned over a slide slot (28) above a projector. Means (26) are provided to restrain the slide in the first receptacle during transit from the initial viewing position to the position wherein the second receptacle is positioned over the slide slot. A second slide in the projector is forced upward by the projector slide lifter mechanism into the second receptacle in the holder, and is retained therein by a latch (52).

Abstract: Apparatus for handling photographic slides is disclosed. According to one aspect of the invention, the apparatus is adapted to support two rotary slide trays disposed one above the other. Means is provided for indexing the lower tray and a coupling member extends between the two trays so that the upper tray is indexed in synchronism with the lower tray. A chute is provided for conveying slides from the upper tray to the lower tray and is shaped to turn the slides laterally so that they enter the second tray in reverse orientation compared with their former orientation in the first tray. Slide loading and unloading devices for use with the apparatus are also disclosed. According to another aspect of the invention, the apparatus is adapted to load stacked slides into a rotary slide tray.

Abstract: A slide projector and a slide cassette usable therewith for projecting slides. The slide projector includes a casing having a central hub located therein. Mechanisms for illuminating and projecting slides are located within the central hub. Also located in the central hub is a slide passage oriented generally vertically. A slide receiving tray in the casing is movable with respect to the central hub and includes a plurality of radially oriented compartments for receiving projected slides. The slide cassette containing slides to be projected has a slide storage tray rotatable with respect to a housing. The housing is releasably held in a predetermined position in the casing.

Abstract: A series of slides are placed in a vertical loader and are movable alternatively into respective ones of two projection positions. Each slide is moved laterally of the loader by a carriage, then pushed to the projection position by a push rod. During projection the following slide in the loader is similarly moved to the other projection position. After its projection, the first slide is brought back by a further push rod to its carriage and then is moved by the carriage to be deposited in a receptacle and be replaced by a new slide which will be moved into the same projection position.

Abstract: A slide viewer/sorter having a chute oriented at an incline to horizontal which is adapted to receive a photographic slide at one end. The slide drops by force of gravity to a viewing station where it is held by a detent. After viewing the slide the detent is actuated to release the slide which is transported by force of gravity to the lower end of the chute where it drops into a first receptacle. The first receptacle is rotatably mounted so that it can be moved out of the way, thus allowing the slide to drop further down into a second receptacle, having a number of bins. The second receptacle is mounted so that any bin can be positioned under the chute. This allows the operator of the viewer/sorter to sort the slides into two or more different stacks.
