Abstract
A slide positioning and holding device includes a base, a number of first bearing members defining a bearing surface for slidably engaging a first edge of the slide, at least one second bearing member for slidably engaging a second edge of the slide generally perpendicular to the first edge, and first and second arms for contact with third and fourth edges, respectively, of the slide to urge the first and second edges of the slide into contact with the bearing members.
Claims23
A slide positioning and holding device, comprising:
- a base movable relative to a viewing apparatus between a first position wherein the slide is viewable by the viewing apparatus and a second position;
- a plurality of first bearing members defining a bearing surface for slidably engaging a first edge of the slide;
- at least one second bearing member for slidably engaging a second edge of the slide generally perpendicular to the first slide edge;
- and,
- first and second arms for contact with third and fourth edges, respectively, of the slide to urge the first and second edges of the slide into contact with the bearing members when the base is in the first position;
- wherein at least one of the arms is caused to move out of contact with the slide by an element fixed relative to the viewing apparatus when the base is moved toward the second position.
A device for holding a slide in a known position relative to a viewing apparatus, comprising:
- a base movable relative to the viewing apparatus;
- at least two bearing members arranged on the base for constraining the slide in two generally perpendicular directions;
- and
- first and second arms, each having a contacting end for contacting an edge of the slide to urge the slide toward the bearing members, each of the arms being rotatably mounted to the base at a point between the contacting end and a distal end and at least one of the arms being operable to contact a projection fixed relative to the viewing apparatus to cause the arms to rotate away from contact with the slide as the base is moved to a position away from the field of view of the viewing apparatus.
A slide positioning and holding device, comprising:
- a base movable relative to a viewing apparatus between a first position wherein the slide is viewable by the viewing apparatus and a second position;
- a plurality of bearing members for constraining the slide in two generally perpendicular directions;
- and
- an arm for urging the slide toward at least one of the bearing members holding it in place when the base in the first position;
- wherein the arm is caused to move out of contact with the slide by an element fixed relative to the viewing apparatus when the base is moved toward the second position.
