PROBLEM TO BE SOLVED: To enable much interaction by processing detection results from plural contact sensors compositely. SOLUTION: In a head sensor 91, when a head exterior member 203 is pressed in the substantially horizontal direction to the array direction of a first contact sensor 201 and a second contact sensor 202, one of the first contact sensor 201 and the second contact sensor 202 is earlier pressed. One of the first contact sensor 201 or the second contact sensor 202 is stronger pressed. When the head exterior member 203 is pressed in the substantially vertical direction to the array direction of the first contact sensor 201 and the second contact sensor 202, the first contact sensor 201 and the second contact sensor 202 are simultaneously pressed. At that time, the head sensor 91 detects the external stimulation as plural kinds of patterns according to a time change or a difference in a detection signal of the pressure detecting result between the first contact sensor 201 and the second contact sensor 202.
