IPC: B41J2/165
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To remove surely ink adhered in the vicinity of a sealing section by using tongues and providing an ink absorbing sheet composed of porous materials having a plurality of tongues being brought into contact with the side of the bottom of the cap sealing section to the extent not disturbing the sealing state in the case of sealing a recording head. SOLUTION: Ink discharged from a recording head is absorbed on ink absorbing sheets 63 and 73 of a top layer, and then the pore diameters are absorbed on the ink absorbing sheets 64 and 74 of a small lower layer by capillary force. Thus the ink impregnating amount of the ink sheets 63 and 73 is in the state of being minimized as much as possible by the arrangement to improve the absorbing force and prevent the adhesion of ink on the recording head and also reduce splashes of ink at the time of forcible discharge of ink. Although the ink is easy to store in thin wall sections and pawls of caps 65 and 75 by the splashes, the tongues are brought into contact with the thin wall sections and pawls in a system mentioned above, and ink is absorbed by the tongues to reduce the residual ink thereon.
