A projector (1) includes a housing (1a), a light source (L) disposed in the housing, a light projection unit (6), disposed in the housing (1a), to project light emitted from the light source (L), a detector (8) to detect a load caused by an object blocking the light projection unit (6), and a microprocessor (20) to activate a protection operation for the projector (1) when the detector detects that the load caused by the object blocking the light projection unit (6) exceeds a threshold load. |
