Abstract
Abstract A slide previewer/tray loader having a holder which is adapted to receive a photographic slide at one end thereof. The holder is initially positioned at an angle above horizontal so that the slide will drop into the holder 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 and edited. The holder pivots in such a manner that the slide can be moved to a vertical position over a slide tray slot. Means are provided to restrain the slide in the holder during transit from the initial viewing position to the position over the slide tray slot. The restraining means releases the slide to allow it to drop into the tray slot.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
96 words
A slide-handling mechanism comprising: means for holding a slide; means for moving said holding means in the vertical plane from a first position to a vertical position; means for restraining said slide in said holding means, including means for allowing said slide to drop from said holding means when said holding means is in said vertical position; and, means for registering said slide-handling mechanism above a slide compartment of a slide tray, such that a slide in said holding means is allowed to drop into said compartment when said holding means is in said vertical position.
Claim 2
Dependent Claim
96 words
A slide-handling mechanism comprising: means for holding a slide; means for moving said holding means in the vertical plane from a first position to a vertical position; means for restraining said slide in said holding means, including means for allowing said slide to drop from said holding means when said holding means is in said vertical position; and, means for registering said slide-handling mechanism above a slide compartment of a slide tray, such that a slide in said holding means is allowed to drop into said compartment when said holding means is in said vertical position.
Claim 3
Dependent Claim
92 words
The slide mechanism in accordance with claim 1 wherein said slide tray is provided with a plurality of slide compartments and wherein said means for registering said slide-handling mechanism above a slide compartment of said slide tray, includes means for allowing relative motion between said slide tray and said slide-handling mechanism so that said slide-handling mechanism may be registered above any one compartment of said plurality of compartments, whereby a slide in said holding means is allowed to drop into said one compartment when said holding means is in said vertical position.
Claim 4
Dependent Claim
121 words
The combination in accordance with claim 1 further comprising: a chute oriented at an incline to horizontal adapted to receive a photographic slide, for providing a passage through which said slide may pass from an upper end of said chute to a lower end of said chute by force of gravity, said chute being located with respect to said holding means such that the lower end of said chute is in alignment with said holding means when said holding means is in said first position; whereby a slide placed in said chute at the upper end thereof drops by force of gravity to the lower end of said chute where said slide exits from said chute and into said holding means.
Claim 5
Dependent Claim
61 words
The combination in accordance with claim 1 or claim 3 wherein said slide tray is provided with a plurality of slide compartments and wherein said means for registering said slide-handling mechanism above a slide compartment of a slide tray includes means for indexing said slide-handling means to a particular slide compartment above which it is desired to register said slide-handling mechanism.
Claim 6
Dependent Claim
32 words
The combination in accordance with claim 3 further comprising: means located above said upper end of said chute for dropping slides, one by one, onto said chute at said upper end thereof.
Claim 7
Dependent Claim
58 words
The combination in accordance with claim 5 wherein said slide tray is provided with a plurality of slide compartments and wherein said means for registering said slide-handling mechanism above a slide compartment of a slide tray includes means for indexing said slide-handling means to a particular slide compartment above which it is desired to register said slide-handling mechanism.
Claim 8
Dependent Claim
92 words
The combination in accordance with claim 5 further comprising: first means for activating said means for moving said holding means to place said holding means in said first position; and, second means for activating said slide-dropping means to thereby drop a slide onto said chute; whereby a slide in said slide-dropping means is dropped onto said chute, where it drops by force of gravity into said holding means and upon deactivation of said first means is moved to said vertical position, where said slide is free to drop from said holding means.
Claim 9
Dependent Claim
58 words
The combination in accordance with claim 7 wherein said slide tray is provided with a plurality of slide compartments and wherein said means for registering said slide-handling mechanism above a slide compartment of a slide tray includes means for indexing said slide-handling mechanism to a particular slide compartment above which it is desired to register said slide-handling mechanism.
Claim 10
Dependent Claim
74 words
The combination in accordance with claims 4, 6, or 8 wherein said slide tray is provided with a plurality of numbers associated with said slide compartments and wherein said means for indexing includes a pointer so that one of said plurality of numbers on said slide tray opposite said pointer can be read when said slide-handling means is indexed to a particular slide compartment above which it is desired to register said slide-handling mechanism.
