Abstract
A photographing- or playback- device for a continuous photo picture carrier which is moved along a guide track by means of a drive device, particularly for motion picture film, with an optical imaging system and at least one mirrored surface which is movable about an axis, particularly a polygonal set of mirrors for the optical equalization of the image shifting as well as a light source if necessary. In the optical path between the guide track of the picture carrier and the mirror there is provided a partially-mirrored surface, which surface is inclined relative to the optical path and forms a part of an autocollimation system. By the partially-mirrored surface a part of the beam rays is deflectable, whereby the axis of the optical imaging system runs inclined or transverse relative to the beam axis (which beam axis runs between the guide track and the mirror) and runs to, or respectively from, the partially-mirrored surface, and the axis of the mirror also is arranged on the beam axis.
