Abstract
A coordinates input device includes an operation unit that receives an operation input, a vibration generator that applies a vibration to the operation unit, and a vibration control unit that controls the vibration generator to apply the vibration to the operation unit when the operation input is received by the operation unit. The vibration generator includes a power feed unit provided to the operation unit, and a magnetic-field applying unit having sub-units. Each of the sub-units has first and second magnets spaced apart from each other with a given gap. The magnetic flux produced by the first and second magnets crosses a current flowing in the power feed unit.
