Information processing system for a computer output microfilmer

摘要

An information processing system is used in a computer output microfilmer in which sub-information such as titles and indices is recorded on a recording medium such as a microfilm together with pre-processed main information obtained from a computer. The pre-processed main information is processed through a main information processing unit. The sub-information is prepared and processed through a sub-information processing unit in which key words contained in the main information are detected and the sub-information is prepared based on the key words. The output of the main information processing unit and the output of the sub-information processing unit are combined and recorded on the recording medium by means of a recorder.
