Abstract
To monitor the picture taking of documents in a camera assembly including a paging device and an exposure device, the documents pertaining to a partial stack of documents are provided with serial page numbers within a digital range assigned to the partial stack. In the exposure device the film pictures are exposed with a blip sign whose shape is assigned to the processed digital range. During the passage of respective documents through the assembly, an electronic control generates in the respective paging and exposure devices binary coded first and second signals assigned to the digital range of the serial numbers and to the corresponding blip signs. The first and second binary coded signals are applied via evaluation units and a comparator into an intermediate memory. After storing in the memory a predetermined count of the first and second signals, the comparator compares the same to reset the intermediate memory when an agreement has been detected or to generate an alarm signal when a disagreement is detected.
