<p>A head-up display (2) has a light source unit (3), a combiner (5), a clip section (9), and a switch section (91). The clip section (9) attaches the head-up display (2) to a sun visor (29) such that the head-up display can be used. On the basis of output signals (S1) supplied from the switch section (91), a control unit (55) of the light source unit (3) detects an attached state of the head-up display (2). Then, when the control unit (55) detects that the attaching state of the head-up display (2) has been deteriorated, the control unit makes the combiner (5) display an image indicating that the mounting state has been deteriorated.</p> |
