Paper cutter having a rotary knife and a stationary knife

摘要

A paper cutter, for cutting paper (5) fed out from a roll (50) so that it can be separated from the roll (50), comprises: a rail (20) having its longitudinal direction extending perpendicular to the paper feeding direction; a stationary knife (12) fixed on and supported by a carriage (10) moving along the rail (20) in the longitudinal direction; and a rotary knife (11) supported by the carriage (10) and rotatable in contact with the stationary knife (12) as the carriage (10) is moved. When the carriage (10) is moved in the longitudinal direction, a cutting edge intersection (14) formed between the rotary knife (11) and the stationary knife (12) crosses and cuts the paper (5) in the width direction.
