ABSTRACT:
A slide projector having a slidably movable magazine with slides, a platform to receive a slide from the magazine, a first support member to transport a slide from the magazine into the platform and a second support to return the used slide from the platform into the magazine. The first support is rigidly mounted on a slidably movable carriage and adapted to push each successive slide from the magazine when the latter is in alignment with the platform. The second support is pivotally mounted on the slide carriage which moves in the direction toward or backward from the magazine. The second support is a three-linked member adapted to engage the used slide to push the latter back to the magazine and having a pin between a first lever and a second lever. A cammed surface is provided in the housing which engages the pin upon slidable movement of the carriage. The cammed surface has a downwardly projecting inclined portion to restrict the movement of the second support toward the magazine after the used slide has been returned into the magazine.
