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.
