PURPOSE:To realize a long life of a lamp, and to execute a correct fixation by moving a reflector to match a size of a recording paper under a flash lamp. CONSTITUTION:A reflector 2 whose section has an inverted trapezoidal shape is fixed to the outside circumference of a flash lamp 1 by which the maximum size of a recording paper 11 can be fixed, and plate-shaped movable reflectors 3, 3' are placed in the lower part of both ends of the reflector 2. The reflectors 3, 3' install linear pulse motor use rails 4,4' to its one side, respectively, and linear pulse motors 5, 5' are provided on the rails 4, 4'. The motors 5, 5' are connected to motor driving circuits 9, 9', respectively, through a linear pulse motor controlling circuit 8 from a CPU7 to which a recording paper size detecting circuit 6 is connected. Also, a circuit extending from the CPU7 to the circuit 8 is made to branch and connected to a flash energy controlling circuit 10. and the circuit 10 is connected to the lamp 1.
