Abstract

PURPOSE:To prevent a cover from vibrating by sensing magnetic flux leaking from the transformer, reactor, etc., of the power unit of a flash lamp and to reduce noises during the operation of the device by covering at least part of the power unit with the cover made of a nonmagnetic body. CONSTITUTION:Discharge electrodes 4 and 4 of the flash lamp 1 are connected to the charging and discharging circuit 9 of the power unit 8 through terminals 51 and 52, and a trigger electrode 6 is connected to the trigger circuit 10 of the power unit 8 through a terminal 7. Then, the whole of the power unit consisting of the charging and discharging circuit 9 and trigger circuit 10 is covered with the cover 11. Charges accumulated in a charging and discharging capacitor 12 are discharged between the discharge electrodes 4 and 4 of the flash lamp 1 through a reactor 18 for discharge control when a trigger pulse voltage is applied to the trigger electrode 6 and then the flash lamp 1 flashes. The cover 11 is made of a nonmagnetic body such as stainless steel or resin and never magnetized with leaking magnetic flux from the transformer 15 and reactors 16 and 18, thereby reducing noises due to vibrations.

.. It will discharge for 4 hours and a flash of light will be emitted from the flash lamp l. The energy of this flash fuses the undefined layer toner image on the recording paper P (FIG. 3) and fixes it on the recording paper P, or the flash energy is stored in the capacitor 12 and supplied by electrical energy Q. As is well known, Q is determined by the formula Q-4CV2. 1, C is the capacitance of the capacitor 12, and ■ is the photoelectric voltage.
