Abstract
A slide projector has a slide exchange element and a slider movable on the latter and having different widths suitable for magazines with different slide compartment widths, wherein the slider is engageable with the slide exchange element under the action of a spring in direction normal to the displacement direction of the slide exchange element, a magazine sensing element senses a magazine inertable into a respective magazine path and provides for disengagement of the slider from the slide exchange element, and an abutment slides in the displacement path of the slider in the disengaged position of the same.
Claims13
A slide projector for framed slides arranged in magazines of at least two different types having different slide compartment widths, the slide projector comprising a slide exchange element for a first magazine with a smaller slide compartment widths and having a portion insertable into and withdrawable from the first magazine in a slide exchange element displacement direction so as to take along a central slide from three slides, said portion of said slide exchange element having a width which is smaller than a distance between one slide and a neighboring slide in the first magazine with the smaller slide compartment width;
- a slider for a second magazine with a greater slide compartment width and movable on said portion of said slide exchange element in said displacement direction over a predetermined path, said slider having a width which is greater than the width of said slide exchange element and smaller than a distance between one slide and a neighboring slide in the second magazine with the greater slide compartment width, said slider being spring-engageable with said portion of said slide exchange element in a direction normal to said displacement direction;
- means forming two magazine paths each for a respective one of the magazines;
- a magazine sensing element extensible into one of said magazine paths for a respective one of the magazines and displaceable upon insertion of the one magazine in said one magazine path so as to disengage said slider from said portion of said slide exchange element;
- an abutment arranged to lie in the movement path of said slider upon insertion of said one magazine in said one magazine path and in the disengaged condition of said slider so as to retain the latter, and to lie out of the movement path of said slider upon insertion of said other magazine in said other magazine path and in the engaged position of said slider so as to release the latter;
- and spring means arranged to urge said slider into engagement with said portion of said slide exchange element.
