<p>PURPOSE:To make possible to transfer at the instant printing is commenced and to eliminate idle hours by a method wherein a film for protection against air leakage is coated on the inner or the outer wall of the accumulator tank to prevent pressure drop of the air in the tank. CONSTITUTION:A tar film 17 is formed on the outer wall (or inner wall) of the sealed tank 15 for a polycarbonate resin accumulator excepting a peep hole 16 on the tank. Since the film 17 hinders permeability of the resin tank and keeps an excellent air-tightness of the tank 15, printing can be commenced immediately after a long time stop of the device. The peep hole 16 is so small that it hardly has an influence on the air-tightness in the tank 15. The film 17 can be formed by painting or be a metallic plated film also.</p> |
