A terminal device capable of preparing a document and communicating data includes a system control section having storage means in which are resident a control program for outputting received document data either to an output section or an external storage, and a supervisor program for alternately practicing the control program and another program necessary for system control. Based on these resident programs, the system control is practiced to permit received document data to be fed to the output section or the external storage even when local work such as preparation of a document is under way. When printing operation is disabled due to a failure in a printer of the output section or the like after the received document data has been loaded in a memory of the communication control, the document data is immediately delivered to the external storage to open the document data storage area. Power is supplied only to the equipments which are indispensable for storing received document data in the memory, except for the duration of any local work such as preparation of document data.
