Abstract

PURPOSE:To effectively use a prepared document even in case when an electric power supply is disconnected, by providing an external memory device having a storing area and a working area, shifting a document stored in the work area to the storing area when a working area effective flag is on, and turning off it flag after the whole document is shifted. CONSTITUTION:This device is provided with a keyboard 1 for inputting a data to a word processor, a control part 2 for controlling the whole device, a picture buffer 4, and a floppy disk device 3 having a store area 9 and a work area 10, and whenever a document of 1 page portion is prepared, the document is stored in the area 10, and when all the documents are prepared, the document of the area 10 is shifted to the store area and is saved. Subsequently, an initializing signal is applied to an initializing control 11, whether a work area effective flag V of the area 10 is on or off is checked, and in case of on, a command for shifting the document of the area 10 to the store area 9 is generated to an external memory control 12. After all the documents are shifted, the flag V is turned off, and in case when disconnection of the electric power supply, a fault of hardware, etc. have occurred, the document stored in the area 9 is used effectively.
