Abstract:
An office information system comprising:a path record storage device which stores a plurality of path records related to components of the system, each path record indicating a locating path needed to reach a location of a specific one of the components in the system when a failure of the specific one of the components occurs; a failure location detecting device which detects a location of a component in the system when a failure related to the component occurs; a reached location determining device which reads a path record from the path record storage device when the location of the failure is detected, and determines a currently reached location in the system based on the path indicated by the path record; and a message device which generates, when the reached location is determined, an operational message needed for recovering the failure at a subsequent location of the path following the reached location, wherein said message device includes: a plurality of optical-output indicators, provided adjacent to the respective components of the system, each of which lights up in response to a light-on signal that indicates the subsequent location in the system; a voice synthesis unit which generates a synthesized voice signal indicating the subsequent location in the system, in synchronism with the light-on signal; and an operation control unit which allows the voice synthesis unit to generate the synthesized voice signal when a voice output mode is selected by a user.
