PROBLEM TO BE SOLVED: To facilitate storage and installation of an image projection screen, to use as a small image screen viewer even in an environment that is bright to a certain degree, and to allow large screen projection in an environment that is dark to a certain degree. SOLUTION: The projector apparatus 1 is provided with a projection lens cover member 22 having a reflecting mirror face, and a support member 26 supporting the projection lens cover member 22 in a desired position. The support member 26 supports the projection lens cover member 22 in the position where a projection luminous flux transmitted through a projection lens 14 and emitted from the projector apparatus 1 is reflected by the reflecting mirror face of the projection lens cover member 22 and forms an image on a transmission type screen 24 connected to the housing of the projector apparatus 1 and in the other position where a path along which the projection luminous flux reaches the projection face of a large screen or the like is not intercepted.
