Abstract

PURPOSE:To satisfactorily accomplish the projection of an image upon the built- in and outside screens by removably mounting a focal plane and distance changing lens in an optical path. CONSTITUTION:The light having passed from its source 3 through a film is projected through a projecting lens 8 and first and second reflecting mirrors 10 and 11 upon a built-in screen 9. When a mirror 11 is turned, the light having passed through the film further passed through a focal plane in the optical path, a focal range changing lens 19 and an optical path changing mirror 18 so that the projected image having its focus and focal point adjusted is formed on an outside screen. As a result, it is possible to project a satisfactory image upon the built-in and outside screens with the use of such small and simple construction. Incidentally, similar results can be obtained if a wide converter of the focal plane and range changing lens is mounted removably in the built-in screen projecting optical path.
