INFORMATION PROCESSOR

PROBLEM TO BE SOLVED: To save the space and improve the usability for a multifunctional device by composing the information processor of a position input and image display hybrid device, and using the processor as a subordinate display device in common and also allowing it to operate independently of a main display device. SOLUTION: A simultaneous scan graphic controller 9 displays a ten-key image on a sub-LCD 3b and also displays an image of an application program on a main LCD 4 (main display device MD). In this state, position information on a key which is indicated is converted by a coordinate detection microcomputer 5 into X and Y coordinate data, which are supplied to a CPU 10 which executes a coordinate processing recognition program 11a through an I/F microcomputer 6 and a system bus. The CPU 10 compares the X and Y coordinate data from the I/F microcomputer 6 with display position information of the simultaneous scan graphic controller 9 and sends the indication key information (number/symbol information) of the ten-key image to the application program.
