Abstract:
In an operation input device enabling multi-screen display, screen display functions are not prevented with each other, and smooth operation input becomes possible, respectively. The operation input device includes a multi-screen display device such as a liquid crystal display device enabling two-screen display on a right-left or up-down side. In addition, a touch panel is provided in a display area of the multi-screen display device. Moreover, a proximity sensor unit is provided around the touch panel. The proximity sensor unit may be formed by plural proximity sensors. The proximity sensor detects fingers of a user approaching the touch panel for operation input, a touch pen and an approach direction of other operation input obj ect. The control unit limits operation input from a direction different from the detected direction. For example, when the operation input device includes a two-screen (right-left-screen) display device, if the approach of the operation input object from the right direction is detected, the control unit makes the operation input from the left direction invalid, and deletes the operation input icon on the screen displayed in the left direction.
