摘要： A SLIDE PROJECTOR AND VIEWER WHEREIN THE HOUSING SUPPORTS A PIVOTABLE INSERT PROVIDED WITH A GATE FOR SLIDES AND CARRYING AN OPTICAL ELEMENT WHICH ACTS AS A MAGNIFYING LENS IN ONE ANGULAR POSITION AND AS A COMPONENT OF A CONDENSING LENS IN ANOTHER ANGULAR POSITION OF THE INSERT. THE PROJECTION LAMP DIRECTS LIGHT THROUGH THE CONDENSING LENS IN THE ONE POSITION OF THE INSERT WHEREBY SUCH LIGHT PASSES THROUGH THE SLIDE IN THE GATE AND THROUGH A PROJECTION LENS SO THAT THE IMAGE OF THE SLIDE IS PROJECTED ONTO A SCREEN. IN THE OTHER POSITION OF THE INSERT, THE OPERATOR CAN LOOK THROUGH THE MAGNIFYING LENS OF THE INSERT AND A SLIDE IN THE GATE TO SEE AN ENLARGED IMAGE BECAUSE THE GATE THAN EXTENDS ACROSS THE PATH OF A SECOND LIGHT SOURCE, EITHER A SEPARATE LAMP OR A REFLECTOR WHICH DIRECTS SOME LIGHT ISSUING FROM THE PROJECTION LAMP AGAINST THE UNDERSIDE OF THE SLIDE.

摘要： The housing of a still camera comprises a body whose front wall carries the lens mount, shutter release trigger and certain other components and which further defines one or more chambers for one or more film magazines. A frame of the body is pivotally connected with a front cover which can be moved to closed position to overlie the front wall and a rear cover which can be moved to a closed position to overlie and to seal the chamber or chambers. Both covers are hingedly connected to a bottom portion of the frame and each thereof can be releasably coupled to the body in closed position. The front cover can be locked in open position in which it permits the operator to use the camera and this front cover can be completely separated from the body to afford access to a socket by means of which the body is connectable to a tripod.
