A motion-picture projector or viewer having a still projection device and having a film track, whose lamp-side part is constructed in the region of the projector gate as a flat glass plate, arranged between the projection lamp and projection lens is to be constructed such that the lamp-side surface of the glass plate is easy to clean or can be cleaned automatically by the flow of cooling air. For this purpose, the glass plate is connected to a heat-absorbing filter in such a way that the latter is flush with the film track holder on the lamp side or projects thereover. <IMAGE>
