Abstract

PURPOSE: To improve efficiency in process by making it possible to obtain any output code from any input code, by recording conversion information on the same recording medium as a recording medium.
CONSTITUTION: In case of using a card reader as an input device, code conversion data is recorded on card 50 through perforation and stored in the code conversion table in the card reader by feeding the card; and then, a normal card is read and the data is converted by this code conversion table before being transmitted to the center side. On card 50, odd columns 1, 2,... express an input code and all combinations among rows Y to 9 are available in the same column; and even columns 2, 4... express an output code against the input code immediately before (8-bit binary display and combinations among columns 2 to 9 are available), so that a code conversion pair will be stored. Namely, the input code of X-2-9 is made to correspond to the output code of 10100110 by columns 1 and 2.
