Linear actuator device

To provide a novel linear actuator driving device which has achieved power saving in correcting offset displacement produced due to self weight of the moving element without any increase in device size, a linear actuator driving device includes an electromagnetic driving unit which makes a moving element reciprocate by carrying out energization in response to a driving command and an offset correcting unit which corrects the driving command to carry out offset energization to make the center of reciprocation of the moving element be moved in the direction in which deviation between the center of reciprocation of the moving element and the center of the movement possible range is eliminated in a case in which, in a non-energized state, the moving element is displaced from the center of the predetermined movable range due to self weight and, therefore, the movable range is narrower than the movement possible range. The offset correcting unit is configured such that the amplitude information corresponding to an
