The present disclosure is an optical control device (60) which controls the angle of a reflecting member (4). The optical control device (60) is provided with a retaining unit (61), an actuator (66), an angle detection unit (67, 67a-67c), and a control unit (70). The angle detection unit (67) is disposed at a location, further outward than the profile of the actuator (66), in an actuator holder (65) in which the actuator (66) is mounted, and detects an angle of rotation of the reflecting member (4). The control unit (70) drives the actuator (66) on the basis of the angle detected by the angle detection unit (67) and controls the angle of rotation of the reflecting member (4).

    本公开是控制反射部件(4)的角度的光学控制装置(60)。光学控制装置(60)具备:保持部(61)、致动器(66)、角度检测部(67、67a~67c)以及控制部(70)。角度检测部(67)设置于载置有致动器(66)的致动器保持架(65)中比致动器(66)的外形更靠外侧的位置,检测反射部件(4)的旋转角度。控制部(70)基于由角度检测部(67)检测出的角度来驱动致动器(66),并控制反射部件(4)的旋转角度。
