Claims (4)
- 筒状の本体の端部に、熱変色性インキの筆跡を摩擦しその際に生じる摩擦熱で該筆跡を熱変色可能な低摩耗性の弾性材料からなる摩擦体を備え、内部に熱変色性インキを収容した熱変色性筆記具であって、前記本体の摩擦体側の端部の外周面に螺合可能な筒状の保護部材を備え、前記本体の端部の外周面にオネジ部を形成し、前記保護部材の内周面に前記オネジ部に螺合可能なメネジ部を形成し、前記保護部材を前記本体に対して回転させることにより、前記保護部材の内側から前記摩擦体を出没可能に構成したことを特徴とする熱変色性筆記具。
- 摩擦体非使用時、前記保護部材が前記摩擦体外周を包囲し且つ前記保護部材の頂部が前記摩擦体の頂部より外方に位置し、摩擦体使用時、前記摩擦体の頂部が前記保護部材の頂部より外方に位置する請求項1記載の熱変色性筆記具。
- 本体の端部に、熱変色性インキの像または筆跡を摩擦しその際に生じる摩擦熱で該像または筆跡を熱変色可能な低摩耗性の弾性材料からなる摩擦体を備えた摩擦具であって、前記本体の摩擦体側の端部の外周面に螺合可能な筒状の保護部材を備え、前記本体の端部の外周面にオネジ部を形成し、前記保護部材の内周面に前記オネジ部に螺合可能なメネジ部を形成し、前記保護部材を前記本体に対して回転させることにより、前記保護部材の内側から前記摩擦体を出没可能に構成したことを特徴とする摩擦具。
- 摩擦体非使用時、前記保護部材が前記摩擦体外周を包囲し且つ前記保護部材の頂部が前記摩擦体の頂部より外方に位置し、摩擦体使用時、前記摩擦体の頂部が前記保護部材の頂部より外方に位置する請求項3記載の摩擦具。
