Abstract: The casing houses the scanning optical system, and includes a holding portion holding an optical element configuring the scanning optical system. The pressing holding member presses and holds the optical element to the holding portion. The pressing holding member includes a body portion and a pressing portion. The pressing portion is coupled to the body portion, and presses the optical element held by the holding portion, against the holding portion. The casing includes a support portion provided to face the holding portion and supporting the body portion. The support portion is disposed on a peripheral edge of a through hole penetrating through the casing, and includes a support protrusion. The support protrusion protrudes from an outer surface to come into contact with a peripheral edge of the body portion. The through hole is an emission port emitting the laser beam to outside of the casing.
