ABSTRACT:
An image projector allowing a lamp to be replaced alone. The lamp has lamp retention projections each extending from the periphery of a reflector. A lamp mounting member includes a plate with which the reflector of the lamp is brought into contact. The plate has a window, leaf springs, and positioning projections. Each of the leaf springs is arranged along the rim of the window with one end fixed on the plate and the other end free, and has a concave portion between the fixed end and the free end. When the lamp is placed on the positioning projections and turned clockwise, each of the lamp retention projections is inserted between the plate and the free end of each of the leaf springs to be received in the concave portion. Thus, the lamp is held on the lamp mounting member. When the lamp is turned counterclockwise, the lamp is released from the lamp mounting member.
