The open space contains a laser having a low operating temperature. The closed space contains a heat generating element and the like, which have higher operating temperatures than the laser. The heat generating element is in close contact with the base, which also serves as a heatsink, so that the heat generating element is cooled. Most parts of a motor, which is a heat generating member, are disposed in the closed space. A fan is diagonally disposed with respect to side surfaces of the heat generating element, which has a rectangular shape and flat side surfaces, so as to efficiently blow air toward the heat generating element disposed in the closed space.
