PURPOSE:To prevent the confusion of a voice recognizing work to attain a high- reliability external trouble reporting system by providing a duplex circuit system consisting of a reporting circuit system, which reports errors of plural input/ output devices through a common bus, and a circuit system consisting of a multiswitching means. CONSTITUTION:If an error occurs in an input/output processing device 11a, it is detected by an error detecting circuit 4a, and error contents are stored in an error register 12a. The register 12a transmits an error signal to an external report switching circuit 15 by the input of error contents. The switching circuit 15 receives the error signal and instructs a multiselecting circuit 14 to read and transfer error contents, and the circuit 14 reads out error contents from the register 12a and transfers them to the external report switching circuit 15. The switching circuit 15 displays transferred error contents on a display device 9, and thus, the occurrence of the error in the input/output processing device 11a is recognized to devise a countermeasure. |
