Abstract: A game machine includes a diorama mounting cabinet on the front side containing a diorama object and a semitransparent mirror and a projector mounting cabinet on the rear side containing a cathode ray tube and a screen. An image displayed on the cathode ray tube is projected onto the screen in such a way that it is superimposed on a virtual image of the diorama object, as viewed form a player. The cathode ray tube and screen are integrally mounted in a projector housing which is made movable within the projector mounting cabinet. This makes it possible to vary relative positions of the individual images in depth directions so that depth relationships therebetween can be changed to provide increased reality and flexibility in three-dimensional visual presentation.
