摘要： A capacitance-type proximity sensor device includes internal electrodes that are arranged such that capacitance is formed therebetween, external electrodes that are arranged in the outer circumference of the internal electrodes, a driving circuit that outputs a driving voltage, a detecting circuit that detects an output signal, a multiplexer that connects an electrode serving as a driving electrode to the driving circuit, connects an electrode serving as a detecting electrode to the detecting circuit, and connects an electrode serving as a shielding electrode to the ground, and a CPU that calculates the position of an object to be detected. When the object to be detected is detected, the multiplexer changes the internal electrodes and the external electrodes to the detecting electrodes, the driving electrodes, and the shielding electrodes.

摘要： In a capacitance detecting device including an offset adjustment circuit for removing offset from charge transmitted to an integrator from a charge reading mechanism, the offset adjustment circuit includes a variable capacitance element switching the number of capacitative elements connected in parallel to a charge transmission line made up of a plurality of the capacitative elements and setting the number to a predetermined capacitance value; and a capacitative element for adjustment connected in parallel to the variable capacitance element and parallel, and having a capacitance value corresponding to the minimum value of the capacitative elements constituting the variable capacitance element. Driving is controlled so that offset removal is performed only N times (M>N; M and N are natural numbers) in the capacitative element for adjustment while offset removal is repeated M times in the variable capacitance element.
