Abstract | To provide an ink ribbon cassette that is able to restrict winding slack of an ink ribbon by urging a supply bobbin and a winding bobbin with appropriate urging forces, while maintaining a small size.SOLUTION: In an ink ribbon cassette having a supply bobbin, a winding bobbin, and a housing composing a supply-bobbin accommodating portion and a winding-bobbin accommodating portion, each of the supply-bobbin accommodating portion and the winding-bobbin accommodating portion has an opening in one side surface of the housing and an elastic piece in this opening and has a rotation restricting portion inside the other side surface. Each of the supply bobbin and the winding bobbin is movable in the direction of a rotation axis and has a rotation-to-be-restricted portion. The supply bobbin and the winding bobbin are respectively urged toward rotation restricting portions by the elastic pieces, and thereby the rotation-to-be-restricted portions and the respective rotation restricting portions are engaged to restrict rotations of the supply bobbin and winding bobbin.SELECTED DRAWING: Figure 3
【課題】 小型を維持しつつ適切な付勢力で供給ボビン及び巻き取りボビンを付勢することで、インクリボンの巻き緩みを規制可能なインクリボンカセットを提供することを目的とする。【解決手段】 供給ボビンと、巻き取りボビンと、供給ボビン収納部と巻き取りボビン収納部とを構成する筐体と、を有するインクリボンカセットにおいて、供給ボビン収納部及び巻き取りボビン収納部それぞれにおいて、筐体の一方の側面には開口と当該開口内に弾性片とが設けられ、他方の側面の内側には回転規制部が設けられており、供給ボビン及び巻き取りボビンは、回転軸方向に移動可能であると共に、被回転規制部を有し、弾性片により供給ボビン及び巻き取りボビンがそれぞれ回転規制部側に付勢されることにより、被回転規制部と回転規制部とが係合して供給ボビン及び巻き取りボビンの回転を規制することを特徴とする。【選択図】 図3 |
