Abstract

A microfilm pickup camera comprises a device for continually horizontally transporting originals to be projected in the camera through the camera, and an ink printing head for marking originals before they enter an exposure station provided in the camera. The ink printing head is provided with a drive which pivots, rotates and displaces the ink printing head between a use position, a cleaning position and a non-operative position. The printing head is EDV-controlled.
