Abstract

The invention provides a device which, in a simple manner, changes the transparency being projected by a transparency projector and which requires only a short interval between the projection of successive transparencies. The device includes two transport members 9, 11, 12 which are so connected that they slide simultaneously in opposite directions. One of the members 11, 12 engages the transparency at the projection station and returns it to the magazine while the other member 9 engages the succeeding transparency and transports it to the projection station. The arrangement is such that the transparencies 4 and 5 are moved along different paths. The part 12 of the transport member 11 and 12 that engages the transparency 4 is pivotable with respect to the rest of the transport member 11 so that, when the transport member 11 and 12 is returned to its original position, it is pivoted out of the projection beam. <IMAGE>
