ABSTRACT:
A computer input system includes a facsimile machine connected to a computer through an interface. A data sheet which is fed to the facsimile machine includes a character pattern row in which a character pattern of data to be entered into the computer is written, and a standard pattern row in which a standard reference pattern corresponding to the character pattern is written. An identification index is marked on the data sheet, and the character pattern, standard pattern, and identification index are transmitted by the facsimile machine from the data sheet to the computer via the interface. The computer includes an arrangement responsive to the character pattern, the standard pattern and the identification index for recognizing and recording the corresponding relationship between the character pattern and the standard pattern.
