An electronic apparatus comprising: a display device having a predetermined display region, apposition detection sensor disposed in a superposed relationship with said display device to detect a position pointed to by a pointer in the predetermined display region, and configured to discretely detect positions pointed to by the pointer at a predetermined time interval, characterized by a plane member having first surface side and a second surface side opposite from the first surface side, the first surface side being configured for use as an operation face for position pointing by the pointer, and said position detection sensor and said display device being disposed at the second surface side, a decision circuit configured to determine, in response to a moving operation of the pointer in a first direction on the operation face, whether or not the moving operation of the pointer in the first direction has passed an end of the predetermined display region of said display device at an end position (Pe), based on a first position (P11, P21) detected by said position detection sensor and a second position (P12, P22) detected at the predetermined time interval after the detection of the first position, a display region end position calculation circuit configured to calculate the end position (Pe) of the predetermined display region of said display device, based on the first position (P11, P21) and the second position (P12, P22) detected by said position detection sensor when it is determined by said decision circuit that the moving operation of the pointer in the first direction has passed an end of the predetermined display region of said display device, and a display controlling circuit configured to control a display screen of said display device in response to the calculation of the end position (Pe) by said display region end position calculation circuit. a display device having a predetermined display region, apposition detection sensor disposed in a superposed relationship with said display device to detect a position pointed to by a pointer in the predetermined display region, and configured to discretely detect positions pointed to by the pointer at a predetermined time interval, characterized by a plane member having first surface side and a second surface side opposite from the first surface side, the first surface side being configured for use as an operation face for position pointing by the pointer, and said position detection sensor and said display device being disposed at the second surface side, a decision circuit configured to determine, in response to a moving operation of the pointer in a first direction on the operation face, whether or not the moving operation of the pointer in the first direction has passed an end of the predetermined display region of said display device at an end position (Pe), based on a first position (P11, P21) detected by said position detection sensor and a second position (P12, P22) detected at the predetermined time interval after the detection of the first position, a display region end position calculation circuit configured to calculate the end position (Pe) of the predetermined display region of said display device, based on the first position (P11, P21) and the second position (P12, P22) detected by said position detection sensor when it is determined by said decision circuit that the moving operation of the pointer in the first direction has passed an end of the predetermined display region of said display device, and a display controlling circuit configured to control a display screen of said display device in response to the calculation of the end position (Pe) by said display region end position calculation circuit.
