Abstract

In a facsimile device, an application program to perform 'concurrent' transmission, multicopy, etc., is divided beforehand into a plurality of phases each being allocated a phase value for identifying purposes. A phase value corresponding to a predetermined phase such as the processing 'wait for an operation' which is to be executed at the beginning of the application program is registered in a non-volatile memory. The following processes are sequentially repeated to execute the appropriate application program: (a) A phase of the application program to be executed is specified in accordance with a phase value registered in the non-volatile memory; (b) The program allocated to the specified phase is executed; and (c) The phase value registered in the non-volatile memory is updated with the phase value of a phase which the program to be executed next is allocated, in response to the ending of the program to be executed. In any case, when the facsimile device is started up, the process (a) is started. Thus, even if the application operation is interrupted due to trouble such as power stoppage, the application operation is continued smoothly when the facsimile is recovered.
