Abstract
PURPOSE:To facilitate the easy insulation between metal and another metal part of a flash device, by applying a coat for insulation on the rear surface of the back metal. CONSTITUTION:An insulated coat 8 is adhered close on the rear surface of a back metal 7. The coat 8 is formed by sticking an electrically insulated tape like a polyester film adhesive tape, etc. to a shining alloy aluminum plate, i.e., a material of the metal 7 with a press process and then forming them into a form of the metal 7. With application of such coat 8, an electrical contact is avoided between the metal 7 and a rail 1 to assure the insulation between the metal 7 and another metal part. Thus the insulation can be facilitated for a flash device.
