The invention relates to a pull-in device for microfilms on a microfilm projector. In order to be able to pull microfilms stored in a cassette mechanically into the microfilm projector with as little outlay as possible, the cassette consists of pivotably mounted plates 17-21 which are stacked one above the other in the manner of a book and between which a microfilm 12-16 is stored in each case. In order to be able to turn up the plates 17-21 by direct access, there is provided on each plate a contact surface 23-27 for a plunger 28, which can be freely accessed from the remaining plates. The exposed microfilm is pulled in by means of a friction roller 31, which can be pivoted over the microfilm. <IMAGE>
