Defined orientation slide projector and slides

A film slide projector for generating images from film slides, the film slide projector comprising:

• a housing;
• a non-rotatable base having a groove and a receiving slot;
• a movable slide holder having:
• a plurality of walls forming a plurality of slots;
• a plurality of cylindrical elements, with each cylindrical element protruding from a respective wall into a respective slot;
• and
• a plurality of cover portions, each forming a respective open aperture of each slot over a respective cylindrical element for receiving a respective film slide to be positioned in the respective slot upon the respective cylindrical element;
• and
• wherein the cylindrical elements cause misoriented film slides positioned thereupon to have a respective portion thereof extending through a respective open aperture to indicate misorientation, and causes the film slides in a predetermined proper orientation in respective slots to be completely contained within the respective slots.

A film slide projector for generating images from film slides stored in slots of a movable slide holder rotatable about an axis, the film slide projector comprising:

• a housing;
• a non-rotatable base having an annular groove and a receiving slot, wherein the movable slide holder moves to slide within the annular groove to move each film slide over a receiving slot for passage therethrough to be positioned near an imaging light source for generating the images;
• a contact sensor for generating detection signals indicating only whether or not a film slide is present in the receiving slot;
• and
• a processor, responsive to the detection signals, for determining whether or not the received film slide is in a predetermined proper orientation, and for controlling the generation of images from the received film slide upon the determination of the orientation of the received film slide.

A film slide projector for generating images from film slides stored in slots of a movable slide holder rotatable about an axis, the film slide projector comprising:

• a housing:
• a non-rotatable base having an annular groove and a receiving slot, wherein the movable slide holder moves to slide within the annular groove to move each film slide over a receiving slot for passage therethrough to be positioned near an imaging light source for generating the images;
• a first magnetic head for generating detection signals indicating whether or not a region of magnetic material is present on a film slide being received in the receiving slot;
• a processor, responsive to the detection signals, for determining whether or not the received film slide is in a predetermined proper orientation, and for controlling the generation of images from the received film slide upon the determination of the orientation of the received film slide;
• and
• a slide push lever, responsive to ejection control signals generated by the processor upon determination that a received slide is misoriented, for ejecting the misoriented received film slide to return to an empty slot in the movable slide holder.

A film slide projector for generating images from film slides stored in slots of a movable slide holder rotatable about an axis, the film slide projector comprising:

• a housing;
• a non-rotatable base having an annular groove and a receiving slot, wherein the movable slide holder moves to slide within the annular groove to move each film slide over a receiving slot for passage therethrough to be positioned near an imaging light source for generating the images;
• a first magnetic head for generating detection signals indicating whether or not a region of magnetic material is present on a film slide being received in the receiving slot;
• a processor, responsive to the detection signals, for determining whether or not the received film slide is in a predetermined proper orientation, and for controlling the generation of images from the received film slide upon the determination of the orientation of the received film slide;
• an output device;
• and
• a second magnetic head, responsive to a region of magnetic material disposed on the base, for generation data signals;
• wherein the processor, responsive to the data signals, causes the output device to generate an identification message associated with the film slides in the movable slide holder corresponding to the region of magnetic material;
• wherein the region of magnetic material disposed on the base is positioned on an underside of the base;
• and
• wherein the second magnetic heads has a detection surface positioned to be substantially adjacent to the region of magnetic material for reading encoded identification data therefrom.
