Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a tractor unit which can realize stable paper feed.SOLUTION: A tractor unit 50 transports a continuous paper R, which has plural engaging holes Q along a transportation direction at both end parts in the paper width direction, by sequentially engaging engaging pins 45 with the engaging holes Q of the continuous paper R. The tractor unit 50 includes: an endless belt 46 on an outer peripheral surface of which plural engaging pins 45 are provided; a drive pulley 47 and a driven pulley 48 over which the endless belt 46 is bridged; and a presser roller 55 which is rotatably disposed in a pressed state on either the drive pulley 47 or the driven pulley 48 via the endless belt 46. 【課題】安定した紙送りを実現できるトラクターユニットを提供する。【解決手段】紙幅方向の両端部分に、搬送方向に沿って複数の係合孔Ｑを有する連続用紙Ｒを、係合ピン４５を前記連続用紙Ｒの前記係合孔Ｑに順次係合させて搬送するトラクターユニット５０であって、外周面に複数の前記係合ピン４５が設けられている無端ベルト４６と、前記無端ベルト４６が架け渡されている駆動プーリー４７および従動プーリー４８と、前記駆動プーリー４７および前記従動プーリー４８のいずれかに、前記無端ベルト４６を介して押圧状態で回転自在に配置される押えローラー５５と、を備える。【選択図】図４
