Abstract
Abstract In a copying apparatus the original and an information characterizing the user is recorded in addition to the copy to be generated for registering the use of the copying apparatus. In order to prevent the original copy to be replaced by a non-recorded other original after recording the original copy comparator means are provided for comparing the recorded original with the original at the respective copying process and interrupting the copying process in case of differences.
