Abstract

A message 6 received or created in a message generating section 10 is stored in a message memory 3. Upon lapse of a stand-by time, a message processing section 15 reads out the message 6 from the message memory 3 for transmission to an external device or for an internal process. When the transmission or the internal process is completed, an ID code attaching section 18 attaches a code indicating that the message 6 has been processed, to the message 6. A database stored in a discrimination database memory 4 describes an effective term with respect to each of contents of the message 6. In response to receiving a restart signal 8 after the operation of an apparatus controlling device 100 is suspended, a message discriminating section 20 causes the message processing section 15 to process the message which has not been processed and whose effective term has not lapsed, among the message(s) 6 stored in the message memory 3. With this arrangement, a proper process is executable with respect to the message which has been left unprocessed by the suspension of the operation of the apparatus controlling device 100, after the operation of the apparatus controlling device 100 is resumed.
