Abstract
A coordinate input device includes a housing containing a movable member, a resilient member formed of a coil spring, and first and second detectors for detecting the sliding direction and the sliding distance of the movable member. The movable member in an initial position before a sliding operation faces a supporter of a first cover provided in the housing. When the movable member is slid in a certain direction, the resilient member is stretched in the certain direction and the first and second detectors detect the sliding direction and the sliding distance of the movable member. When the sliding operation of the movable member is finished, a resilient force of the resilient member stretched in the certain direction forces the movable member to return automatically to the initial position.
