A display control unit (101) displays a key image, which serves as an operation target, etc. on a display unit. An area memory unit (103) stores a reception area (area information) corresponding to the displayed key image. A detecting unit (104) senses a user's touching operation and detects its touch position. A determining unit (105) makes determinations whether the detected touch position is within the range of the reception area stored in the area memory unit (103), etc. A time measuring unit (106) measures a time period that has elapsed since the touching operation. When a touching operation is detected, an area control unit (107) expands a reception area that includes the touch position to a predetermined range. Thereafter, the area control unit (107) reduces the expanded reception area to its original size when the time measuring unit (106) measures a predetermined time period.
