A conductive material such as silver is charged in a via hole of an insulative substrate made of low-temperature-sintered ceramic. The conductor pattern has the effect that the intrinsic field of the operating current through the Hall element is suppressed outside the Hall element such that the Hall element effects an at least reduced offset in adjacent Hall elements. Consequently, the overall length can be shortened in comparison to a prior art movable body dispensing device, whilst maintaining the same dispensing amount, and hence satisfactory downsizing can be achieved. The touch is detected, and a communication signal is determined based on a number of the touch and a duration of the touch. The ink drop generators are arranged in at least four parallel rows.
