Abstract
PURPOSE: To eliminate error inputting, by preventing a code converter from operating even if any multiple-item switch closes when an input inhibit switch closes.
CONSTITUTION: According to inputs of item input switches SW2...SWn, code converter A outputs data DL1...DLm, and output SD1 of input inhibit switch SW1 is supplied to converter A. When switch SW1 is opening, the closing of one of switches SW2...SWn outputs fixed data of DL1...DLm to the data line of converter. When switch SW1 is closing, however, converter A will not be operated even if any one of swithces SW2...SWn. Consequently, the error inputting to the book-system multiple-item input device, etc., can be prevented from occurring during the replacement of the book.
