その利用価値を頗る高めることができる。 As described above, according to the knock-type sharp pencil of this invention, the knob body is removably fitted to the rear end of the outer cylinder, and the knob part, the ballpoint pen, the tip shaft part, and the fitting elastic piece are provided. When the ballpoint pen is inserted into the rear end of the outer barrel, the knob tube can be used as a knob to allow the lead of the sharp pencil to be fed out, and the ballpoint pen can be inserted into the outer barrel by inverting the knob body. It is configured so that it can be used as a ballpoint pen when it protrudes from the rear end (when used as a ballpoint pen), so it can be used normally as a regular sharp pencil, and when necessary, it can be used as a ballpoint pen.
Its utility value can be greatly increased.
しかも、ノツク体は外筒に対して確実に挿着支
持され、使用中に脱落する虞れは全くなく、また
芯筒の後蓋としても機能する等極めて優れた実用
的効果がある。 Moreover, the knob body is securely inserted into and supported by the outer cylinder, there is no risk of it falling off during use, and it also functions as a rear cover of the core cylinder, providing extremely excellent practical effects.
尚、上記ノツク体４のノツク筒６に第１図の点
