Patent ID: 8641195

Claim:
An image forming apparatus comprising: a projector configured to be capable of projecting light to thereby display an image on a rendering region formed on a display surface set around a guiding point to which a person should be guided and changing a position of the rendering region; a detecting unit that detects whether a person is present in a detection region set near the display surface and detects, when a person is present in the detection region, a moving state of the person; a control unit that controls, on the basis of a detection result of the detecting unit, driving of the projector to guide the person present in the detection region to the guiding point; a light emitting unit that emits a laser beam; and a light scanning unit that scans the laser beam emitted from the light emitting unit in a first direction and a second direction orthogonal to each other, wherein the projector includes a unit pivoting unit that pivots the light emitting unit and the light scanning unit integrally around at least one axis of two axes orthogonal to each other.
