Abstract
A laser scanning device includes a light source, a rotary polytope, a motor, a bearing, and a detection processing portion. The rotary polytope scans light emitted from the light source. The motor rotates the rotary polytope. The bearing rotatably supports a rotation shaft of the motor. The detection processing portion, in a case where the motor is driven at a first speed that is higher than a predetermined reference speed, performs detection of an abnormal state based on an atmospheric temperature detected at a position located within a predetermined first range from the bearing, and in a case where the motor is driven at a second speed that is lower than the reference speed, does not perform the detection of the abnormal state, wherein the abnormal state is a state where the temperature of the bearing has exceeded a predetermined allowable temperature.
