Abstract

PURPOSE:To use in common a storage device of an input side, and to eliminate the limitation by the number of information destinations, by storing an informed external signal and the proceeding external signal, comparing the new and old signals by an indication of a detecting signal indication device, and detecting its variation. CONSTITUTION:An external signal is stored in a storage device 2 under the control of a multi-data transmitting device 3 through an input device 5. Information stored in the device 2 is transferred to a storage device 6 of each information destination in a prescribed period through the device 3. Information stored in the device 6 is stored successively in an old signal storage device 7. The new information stored in the device 6 and the old information stored in the device 7 are fetched in accordance with a place designated by a detecting signal indication device 9, comparison of the new and old information is executed by a signal variation detecting device 8, and a state variation is detected. In this way, even if a signal generating source of an input side exists at one point, the variation of an external signal can be detected individually by many information destinations.
