INK CARTRIDGE AND METHOD FOR TAG DISCRIMINATION IN THE SAME

PROBLEM TO BE SOLVED: To facilitate the discrimination work at the time of cartridge disposal.SOLUTION: An engagement part 30 fitted in an outer package 20 of an ink cartridge 1 is provided with: a fit-in rib 34 which is provided at a circumferential edge on a rear side and which serves as a guide upon engagement with an opening of the outer package; an engagement rib 35a provided upright at the circumferential edge of the engagement hole 35 in the same direction as a direction of the fit-in rib 34; and a bonding region D for bonding a communication tag 36 that performs near field radio communication with a printer 100. A tag-removing hole 37 which is formed in the bonding region D and which is to be removed from a bonding surface side of the communication tag 36 with a bar-like member inserted is formed in a formation region Ea as the bonding region D located in a first quadrant and a fourth quadrant in an orthogonal coordinate system having, as coordinate axes, virtual lines X and Y having an origin at a center O of a virtual circle VC formed by linking together end parts of a circular arc part of the bonding region D.SELECTED DRAWING: Figure 4 【課題】カートリッジ廃棄時における分別作業を容易にすること。【解決手段】インクカートリッジ１の外装体２０に嵌合される係合部３０は、裏面側の周縁に外装体の開口と嵌合するときのガイドとなる嵌合リブ３４と、係合孔３５の周縁に嵌合リブ３４と同方向に立設される係合リブ３５ａと、印刷装置１００との間で近距離無線通信を行う通信タグ３６を貼着する貼着領域Ｄとが設けられている。また、貼着領域Ｄ内に形成され棒状部材を挿入して通信タグ３６の接着面側から剥がすためのタグ剥がし孔３７は、貼着領域Ｄの円弧部の各端部を結んで形成される仮想円ＶＣの中心Ｏを原点とする仮想線Ｘ、Ｙを座標軸とした直交座標系における第一象限及び第四象限内の貼着領域Ｄである形成領域Ｅａ内に形成される。【選択図】図４
