Abstract
A portable type information device includes: a projector device that, with illumination light from a light source unit, projects a projection pattern which has been created upon an image pattern generation unit to an exterior of the portable type information device via a projection lens; and a power supply command device that commands the projector device to turn ON only a power supply to the light source unit. The projector device is configured to be utilized as a simple electric torch. In addition, by retracting the image pattern generation unit from an optical path for projection, the illumination light can be irradiated to the exterior effectively.
