<p>PROBLEM TO BE SOLVED: To discriminate coordinate input from a clock operation and to realize a click function with an operation sense by operating an upper panel as a touch panel, inputting a coordinate and operating a key sensor by pushing down the upper panel. SOLUTION: A mouse pointer moves on the display of a portable terminal by touching on a touch panel part 12 with a coordinate 18 on the upper face of an input device 11 and the coordinate can be designated. When the touch panel part 12 is strongly pressed downward as it is, a protrusion part 15 pushes the key sensor 16. When pushing force is released, the key part of the input device 1 is restored to an original state with the force of a spring 17. Since a signal can be inputted to the key sensor 16 with such a pushing down operation, a click operation can be realized. Thus, an input operation as a click key is completely detached from a coordinate input operation from the touch panel part 12 and the click function with the operation sense and coordinate input with less error and with superior operability can be realized.</p> |
