ABSTRACT:
A flash emitting apparatus has a straight-tube type flash discharge tube and a reflector for accommodating the flash discharge tube which condenses and reflects an emission of the flash discharge tube to direct light forward, the apparatus including: a pair of electrodes disposed on opposing end portions of said flash discharge tube; discharge tube supports for supporting the flash discharge tube on said reflector; a frame member having said flash discharge tube and said reflector disposed therein; and restriction members formed internally of said frame member for restricting movement of said flash discharge tube in a longitudinal direction coaxial with a line connecting the pair of electrodes so as to retain the flash discharge tube within a certain range with respect to the reflector.
