Abstract
Abstract A format pattern carried on a format transparency is photoelectrically converted into an electric signal. The electric signal representing the format pattern is inputted into an "exclusive-or" circuit together with a character pattern signal representing output information of a computer. The output of the "exclusive-or" circuit controls an on-off modulator which modulates a laser beam for recording the output information of the computer. The modulated laser beam is deflected by a beam scanner to scan a photosensitive or heat sensitive film to record thereon the format pattern together with the computer output information.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
132 words
A format-information synthesizing system comprising a character pattern signal generating means which generates a character pattern signal in accordance with the information to be recorded, a format pattern signal generating means which generates a format pattern signal by converting a format optically recorded on a format transparency into an electric signal, an "exclusive-or" circuit which receives the character pattern signal and the format pattern signal which are inputted thereinto in synchronization with each other, a laser source, an on-off modulator which modulates a laser beam emitted from the laser source in accordance with the output of the "exclusive-or" circuit, and a beam scanner which deflects the modulated laser beam to scan the surface of a recording medium to record the synthesized pattern of the information and the format on the recording medium.
Claim 2
Dependent Claim
132 words
A format-information synthesizing system comprising a character pattern signal generating means which generates a character pattern signal in accordance with the information to be recorded, a format pattern signal generating means which generates a format pattern signal by converting a format optically recorded on a format transparency into an electric signal, an "exclusive-or" circuit which receives the character pattern signal and the format pattern signal which are inputted thereinto in synchronization with each other, a laser source, an on-off modulator which modulates a laser beam emitted from the laser source in accordance with the output of the "exclusive-or" circuit, and a beam scanner which deflects the modulated laser beam to scan the surface of a recording medium to record the synthesized pattern of the information and the format on the recording medium.
Claim 3
Dependent Claim
57 words
A format-information synthesizing system as defined in claim 1 wherein said format pattern signal generating means comprises a laser source, a beam scanner for deflecting a laser beam emitted from the laser to scan the format transparency, and a photoelectric converter which converts intensity of the laser beam transmitting through the format transparency into an electric signal.
