Title: Stopper opening structure of ink tank
Inventor: FURUICHI AKINORI
IPC: B43K5/14
Filed: 2000-09-29
Abstract: PROBLEM TO BE SOLVED: To solve such a trouble that an ink tank is conventionally structured in such a manner as to activate an elastically deformable protrusion part provided on a stopper to push an ink guide member so that the opening of the ink tank stopper increases but this member comes off depending upon the way the member is fixed, to adversely affect the writing. SOLUTION: This stopper opening structure of the ink tank opens the stopper integrally molded with the ink tank by bringing a pressurizing element into contact with the stopper. The protrusion part which comes into contact with the pressurizing element after the start of a contact action between the stopper and the pressurizing element, is formed on the stopper, on the front side of the stopper and/or near the contact part between the stopper and the pressurizing element. Thus the opening of the stopper is prompted by a reaction generated by the contact between the protrusion part and the pressurizing element.
