发明名称 FLASH LIGHT GENERATING DEVICE
摘要 PURPOSE:To make a device small-sized, by forming a reflector against a flash tube, also providing a press-contact coupling part on a part of a back metal connected to a transparent electrode part of the flash tube, and press-contacting an electric conductor part for trigger, to said coupling part. CONSTITUTION:On the front surface of a housing 2 storing a flash tube 6, a Fresnel lens 4 is firmly fixed, and irraidates a light beam onto an object to be photographed. A reflector 5 is coupled with a back metal 7 at the part of a screw hole 7a with a screw, and the reflection mirror is formed by both of them 5, 7. The back metal is made of a bright alloy, a projecting part 7b is provided, and when the flash tube 6 is pressed against the projecting part 7b, the flash tube 6 is located against the reflection mirror, and also a transparent electrode part for trigger, with which the outside wall of the flash tube 6 is coated, and the back metal 7 are made to contact electrically.
