A printing machine capable of printing characters on two kinds of paper sheets, long paper sheets and short paper sheets, comprises two paper holder members movably provided relative to a paper feed roller to cause the long paper sheet to be clamped between the paper holder members and the paper feed roller, and a drive mechanism for moving the paper holder members to clamp a long paper sheet between the paper holder members and the paper feed roller when a pinch roller is pivoted away from the paper feed roller by another drive mechanism in order to set a short paper sheet into a space between a platen and a printing head. |
