Abstract
Data sets DSto DSeach consisting of plural linear functions obtained by approximating an output characteristic of a Y-axis rotation position detection Hall element Hand a data set DSconsisting of plural linear functions obtained by approximating an output characteristic of an and the X-axis position detection Hall element Hare stored for each of plural positions in a direction X in a ROM of a memory. A system controller detects a position of a movable member in the direction X based on the data set DSand an output signal of the X-axis position detection Hall element H, then selects the data set corresponding to the position among the data sets DSto DS, and detects a position of the movable member in a direction Y based on the selected data set and an output signal of the Y-axis rotation position detection Hall element H
