Abstract
An information input device is provided which is to make input of information by operating a disk-shaped rotating member. The device includes the rotating member () which is rotatable with one main side thereof being operated, rotation detecting means () for detecting a rotation of the rotating member (), a central switch activator () provided at the center of rotation of the rotating member (), a central switch () which is activated by operating the central switch activator (), and a plurality of peripheral switches () which are turned on when a portion, apart from the center of rotation, of the rotating member () is pressed. Rotating the rotating member and pressing the apart portion makes input of information, and operating the central switch activator sets the information thus entered.
