To shorten adjustment processing time of an elastic vibration.SOLUTION: A movable device of the invention comprises: a reflection part; a pair of movable parts which applies each inclination to the reflection part; and a control part for inputting a drive signal for applying inclination to the pair of movable parts. The control part comprises: a drive signal generation part for generating a drive signal in which, a standing ratio of the drive signals to be input to the pair of movable parts, and a phase difference between the drive signal are variable numbers; a high frequency component extraction part for extracting a high frequency component from a signal corresponding to a vibration angle of the movable part, the vibration angle being detected by driving by the drive signal generated by the drive signal generation part; a memory part for associating values of the variable numbers of the drive signals with the high frequency component and storing them; and a drive signal selecting part for selecting a combination of the values of the variable numbers for updating the drive signal, on the basis of the high frequency component stored in the memory part.SELECTED DRAWING: Figure 17

    【課題】弾性振動の調整処理時間を短縮すること。【解決手段】本発明にかかる可動装置は、反射部と、反射部にそれぞれの傾きを与える一対の可動部と、一対の可動部に傾きを与える駆動信号を入力する制御部と、を有し、制御部は、一対の可動部にそれぞれ入力する駆動信号の立ち上がり比と駆動信号間の位相差とを変数とする駆動信号を生成する駆動信号生成部と、駆動信号生成部が生成した駆動信号による駆動で検知される可動部の振れ角に対応する信号から高周波成分を抽出する高周波成分抽出部と、駆動信号の変数の値と高周波成分とを紐づけて格納するメモリ部と、メモリ部に格納された高周波成分に基づいて、駆動信号を更新する変数の値の組み合わせを選択する駆動信号選択部と、を有する。【選択図】図17
