## Abstract

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.

## Claims

### Claim 1

An information processing system for 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 processed main information comprising an input means responsive to a computer which pre-processed said main information, a main information processing means for processing the pre-processed main information to provide said processed main information, a sub-information processing means, and an output means responsive to the main information processing means for recording on said recording medium, said main information processing means including (a) means for processing the pre-processed main information read out from said input means, (b) means for transferring the processed main information to said output means, (c) means for controlling the recording of the processed main information transferred to said output means onto said recording medium, (d) means for detecting key words that are part of said titles or indices and predetermined commands from said pre-processed main information read out from said input means, and (e) means for transferring the detected key words and predetermined commands to said sub-information processing means as input information thereto, said sub-information processing means including (a) means for preparing said sub-information including said titles or indices based on the key words thereof when the same has received said key words from said main information processing means, (b) means for transferring said prepared sub-information to said output means when the sub-information processing means has received said predetermined commands and (c) means for processing the sub-information at the same time said main information processing means is processing the pre-processed main information and controlling the recording of the processed main information and said main information processing means further including means for controlling the recording of the sub-information after the pre-processed main information has been processed.

### Claim 2 (depends on 1)

An information processing system according to claim 1 wherein said main information processing means and said sub-information processing means are micro-computers.

### Claim 3 (depends on 1)

An information processing system according to claim 1 wherein said output means is a cathode ray tube character display device.

### Claim 4 (depends on 1)

An information processing system according to claim 1 wherein said output means is a laser beam scanning recording device.
