More Information
Summary:An electronic device (1) includes a projection device (2) configured to project a light to a projection region (Aa) on a projection surface (F) and a detection device (3) separately disposed from the projection device (2). The detection device (3) includes a light detector (31) configured to detect a reflected light of the light projected from the projection device (2) and a notification light emitter (37) configured to emit to the projection surface (F) a notification light for indicating an inclination of the light detector relative to the projection surface (F). The notification light emitter (37) is further configured to emit the notification light in directions respectively fixed relative to the detection device (3) from a plurality of locations in the detection device (3), and each notification light passes through a same point on the projection surface (F) when the detection device (3) is installed at a predetermined inclination relative to the projection surface (F).
