A projector section is lined up, separated from a head section, on a side that a mirror is provided in the head section. A path for light reflected by the mirror is positioned further than the projector section on one side in a direction intersecting a direction in which the head section and the projector section are lined up. A wall section on the head section-side in a case has a covered section and an extension section. The covered section is covered by the head section and has provided therein an emission section having projection light emitted therefrom. The extension section extends to the opposite side to the reflected light path side, relative to a space between the covered section and the head section. An exhaust port that discharges air from inside the case is formed in this extension section, on the opposite side to the space side. |
