Abstract
An improved switchover device includes input terminals connected with information sources, first and second output terminals connected with information processing devices, switching elements for effecting switchover connection between the input terminals and the output terminals and a switchover control circuit for controlling the switching elements. When information from one information source is being supplied to the information processing devices and there is an interrupt request for supplying information from another information source devices, the switching element between the input terminal of the one information source and the first output terminal is made OFF, while the switching element between the input terminal of the other information source and the first output terminal is made ON. The switching element between the input terminal of the one information source and the second output terminal is kept ON. Thus, the information processing devices are allowed to respectively process information from a plurality of information sources.
