Abstract

PURPOSE:To effectively use devices and to realize man-power saving of the operator, by automatically connecting a card to any of data processing systems based on information on an inputted card. CONSTITUTION:When a system switching card is inputted, it is read at a read section 10 and set to a buffer 13. In this case, the content of a column counter 14 shows 1 and a decoding circuit 16 outputs 1 signal. The content of the buffer 13 is * symbol and a decoder 15 outputs * signals. Thus, the output of an AND circuit 17 goes to 1 and an FF20 is set. When the 1-th column information is set to the buffer 13, AND circuits 18 and 19 are opened, and if the i-th column information goes to 1, the circuit 15 outputs 1 signal and an FF22 is set. If the i-th column information goes to 2, an FF21 is set. When the FF22 is set, a alteration switching section 12 is changed over to the system 1 and when the FF21 is set, the section 12 is changed over to the system 2.
