PURPOSE: To improve an operability at the time of inputting document information with a stylus pen by providing a display screen at each opposed face of an original placing part and an opening and closing member which can be folded, and controlling the serial display or divided display of the document information.

CONSTITUTION: Each document information is displayed on first and second display screens at each opposed face of the original placing part and the opening and closing member which can be folded. A display control part 9 controls the serial display or divided display of the document information of each display screen 11 and 12. And also, a document information input accompanied with a pen sense can be operated on the second display screen 12 by a pen position detector 10 at the lower face side of the second display screen 12. Thus, for example, the processing of the input of a document retrieval can be operated on the second display screen 12, and the retrieved result can be displayed on the first display screen 11, so that the operability at the time of inputting the document information with the stylus pen can be attained. And also, the document information can be transition-displayed between each display screen 1 and 2, or the serial display of the document information can be operated on the screens 1 and 2, so that the display information can be increased.
