ABSTRACT:
A foam unit for storing ink includes a porous member impregnated with ink and a film member wrapped around the porous member. A foam storing case has an opening for allowing insertion and removal of the foam unit into and from the case and a lid adapted to engage with the opening of the foam storing case. When the foam unit is inserted into the foam storing case, an O-ring engages with a projecting portion, and the film is burst by the projecting portion causing the foam member to abut against a filter. Then, a lid is fitted to the opening of the foam storing case. Thus, the foam unit is quickly and neatly replaced, and the ink impregnated in the replaced foam unit can be supplied to a print head.
