従来、この種の截断装置としては、第１図に示すように
半円筒状に丸められた紙０と同一の曲率半径をもつ固定
台１と円板状の刃物２を有し回動桿３によって刃物２を
固定台１に強く押し付けながら回転して紙Ｏを截断する
ものが用いられていた。
この截断装置では、刃物２の刃先が固定台１に直接強く
圧接されるため、刃物２または固定台１のいずれか一方
あるいは両方が早期に摩耗損傷してしまい、紙を切断す

本発明は上記欠点を解決し、より長寿命で信頼性の高い
截断装置を得ることを目的とするものである。

この条件と弾性体を用いることと相俟って切断性がよく
長寿命の截断装置を得ることができる。
また角θ（截断角）を適宜選定することにより、截断力
を変えることもできる。
本発明を実施例について説明する。
第３〜５図において固定刃１１は丸められた紙０と同じ
曲率半径１００ｍｍの半円形凹型の刃部を有し、９８ｍ
ｍ半径の円形の刃部を有する可動刃１２は、皿ばね１３
を介して偏心軸１４に固着されている。
固定刃１１と可動刃１２との中心間距離は１０ｍｍであ

に圧接される。
偏心軸１４にモーターのような回転駆動源（図示せず）
を連結駆動することにより、固定刃１１と可動刃１２の
間に位置する半円筒状に丸められた紙を固定刃１１と可
動刃１２とが切断中常に１点で交接し、良好な截断を行

第６〜８図は可動刃２２を駆動する他の実施例であり、
上記実施例と同様に固定刃２１の半径は１００ｍｍ、可
動刃２２の半径は９８ｍｍ、中心間距離は１０１ｍｍで
ある。
固定刃２１と可動刃２２は２組のリンク２３によって連

定刃２１に圧接する。
リンク２５は左右のリンク２３が死点に位置して可動刃
２２の動きが不安定になるのを防いでいる。
可動刃２２は平行回転するので回転駆動源（図示せず）
を可動刃２２の任意の位置に取付けることが可能であり
、偏心軸２６の位置にモーターを取り付けて紙Ｏの截断
を切断性良く行なうことができ、寿命を延長することが
できる。
第９〜１１図は可動刃３２を駆動する他の実施例であり
、固定刃３１の半径１００ｍｍ，可動刃３２の半径９６
ｍｍおよび中心間距離６ｍｍに設定した。
固定刃３１と可動刃３２とはピン３３によって互いに回
転できるように連結され、ピン３３と同じ軸に取り付け

されている。
可動刃３２の一端に設けられたレバー３５を用い、手動
により紙０を截断するのに特に適している。
この装置も良好な截断ができ著しい耐久性を有する。
実施例においては円形および半円形の刃部を有する可動
