DEVICE FOR MEASURING INTERPUPILLARY DISTANCE

摘要

The present invention relates to a device for measuring interpupillary distance. The device of the present invention comprises: a housing; a light source; a reflecting mirror for reflecting the light irradiated from the light source toward a pair of visible windows placed in the housing; a lens installed along an optical path between the pair of visible windows and the reflecting mirror to be movable; a lens control lever for moving the lens; a first side pointer installed in the first visible window to be movable; a first side pointer control lever for moving the first side pointer; a first side pointer position sensor for detecting the position of the first side pointer; a second side pointer installed in the second visible window to be movable; a second side pointer control lever for moving the second side pointer; a second side pointer position sensor for detecting the position of the second side pointer; a display for displaying information; a calculating unit for receiving detection information of the first side pointer position sensor and the second side pointer position sensor and calculating the interpupillary distance of the subject; an operating mirror installed on the optical path to be able to change the angle; an operating mirror control lever for changing the angle of the operating mirror; and an inclined mirror for reflecting the light reflected by the operating mirror to be inclined upward toward the pair of visible windows.
