Publication number: 20090021491Abstract: 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 object. The control unit limits operation input from a direction different from the detected direction.Type: ApplicationFiled: February 23, 2007Publication date: January 22, 2009Applicant: PIONEER CORPORATIONInventor: Katsuaki Kawamura
