Abstract
A coordinate input device includes an operation unit that is provided so as to be operated, strain sensors that output data corresponding to an operation amount of the operation unit, and a control unit. The control unit performs the count corresponding to the increase or decrease of speed data that is obtained by converting data sequentially output from the strain sensors, and generates counted count values or coordinate data calculated from the count values. The control unit calculates a moving average value from the count values that are sequentially output every predetermined time. When the moving average value satisfies predetermined conditions, the control unit regards that the operation of the operation unit is cancelled, and stops the output of the coordinate data or outputs 0 as the count value.
