装置。[Claims for Utility Model Registration] An AC output circuit that outputs an AC voltage with a frequency higher than the frequency of the AC voltage applied to the electroluminescent element, and a transformation that boosts the AC voltage output from the AC output circuit. A conversion circuit that converts the AC voltage boosted by the transformer into a DC voltage, and a conversion circuit that switches the DC voltage converted by this conversion circuit and alternately applies it to both electrodes of the electroluminescence element. A driving device for an electroluminescent sensing element, comprising a driving circuit that drives the sensing element with alternating current, and a control circuit that controls the switching operation of the driving circuit.
