Abstract

(57)【要約】 【目的】 2種の着色系の筆記体と、その筆記を消色可 能とする塗布体を具備した複式筆記具に於いて、携帯 性、使い勝手性を満足した軸体の太さで提供可能とす る。 【構成】 筆記具の前方に2種の筆記体を収納して、夫 々の筆記先端部を選択的に軸先から出没可能とすると共 に筆記具の後端に塗布体を備えた複式筆記具に於いて、 筆記体は、インキ収容管のインキ収容部が比較的大きな 断面積を有した非変形のものであって、インキ収容部に 着色系のインキが充填され、筆記先端部とインキ収容部 を接続する部位が軸長方向に対する横方向に容易に変移 可能と成されて筆記先端部が容易に求心されて軸先孔か ら出没可能となり、塗布体は、筆記体による筆記描線を 塗布することで消色可能とする塗布液が充填されて成 る。
PROBLEM TO BE SOLVED: To obtain a convenient combined writing utensil by easily shifting the part which connects an ink holding part to a note-taking tip part in the cross direction for the direction of barrel length and easily making the note-taking tip part centripetal to enable it to come in and out from the tip hole of a barrel. SOLUTION: The combined writing utensil consists of writing bodies 1a, 1b, the front barrel 52 and a middle barrel 30 which house the rising and setting mechanism thereof, a coating body 60 and the rear barrel 43 housing the rising and setting mechanism thereof. When the color indicator 56 of an internal cylinder is rotated for the rear barrel 43, the projection 63 of the coating body 60 is slid along a slit 39. The rear end part 40 of the rear cylinder part of a barrel part 37 has a slope and the abutting part 58 of the internal cylinder accommodating thereto is made to a slope. The rear end of the cylinder part having the slit 39 is prevented from being reduced in a diameter toward the inner part. The ink holding part of an ink holding tube has a comparatively large cross section and is deformable and has a nearly D-shaped sectional shape which is efficiently inserted into the middle barrel 30. Further, the part which connects the ink holding part to a chip 11 is easily shifted laterally with respect to the direction of barrel length. COPYRIGHT: (C)1997,JPO
