发明名称 Electronic Device
摘要 An electronic device includes a projector device that projects an image formed by an optical image formation element via a projection optical system towards a projection surface external to a body of the electronic device; and the projector device projects the image while determining an orientation of the projection light flux, so that neither in a first placement method, in which the electronic device is placed with a first surface of the body being downwards upon a plane upon which the electronic device and the projection surface are placed, nor in a second placement method in which the electronic device is placed with a second surface of the body that is different from the first surface being downwards, is the image projected from the projector device intercepted by the plane.
