Abstract
A piston-type ink container is inserted into an ink container holder of a stencil printer so that an ink suction nozzle of the stencil printer is fitted in a small diameter portion of the ink container to suck the ink in the ink container through an ink discharge port on the tip of the small diameter portion. A vacuum release mechanism at least partly releases vacuum in the space evacuated by the ink suction nozzle before the tip of the nozzle and the tip of the small diameter portion are aligned with each other when the ink container is drawn from the ink container holder.
