An improved switchover device comprises 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. During a process in which information from one information source is being supplied to the information processing devices and, once there is an interrupt request for supplying information from another information source to the information processing devices, the switching element between the input terminal and the output terminal is made OFF, while the switching element between the input terminal and the output terminal is made ON. At this time, the switching element between the input terminal and the output terminal is kept ON. In this way, during a process in which information from one information source is being supplied to the information processing devices, once a different information is transmitted from another information source, the information processing means are allowed to respectively process the two different information.
