PURPOSE:To prevent the occurrence of rubber chips when a title stylus is sticked into a rubber cap of an ink cartridge by a method wherein the outer diameter of a second hollow stylus is not larger than the bottom diameter of a sticking tip of a first hollow stylus, and the bottom periphery of the sticking tip and the tip end of the second hollow stylus abutting thereto are in close contact with each other at right angles to an insertion direction or in a tapered from. CONSTITUTION:A sticking tip 12 of a first hollow stylus 13 is provided so as to cover the tip end of a second hollow stylus 14 at the bottom periphery thereof. The outer diameter of the second hollow stylus 14 is not larger than the bottom diameter of the sticking tip 12 of the first hollow stylus. The bottom periphery 12a of the sticking tip 12 and the tip end 14a of the second hollow stylus 14 abutting thereto are in close contact with each other at right angles to an insertion direction. When the stylus is sticked into a rubber cap 4a of an ink cartridge 4, the tip end 14a of the second hollow stylus 14 is covered with the sticking tip bottom periphery 12a of the first hollow stylus 13 so as not to directly abut against the rubber cap, thus having no possibility of scraping off the rubber cap 4a and generating rubber chips. |
