Claims

[Scope of Claim for Utility Model Registration] A cutter mounting rod that is provided with a paper holding portion and is movably arranged in accordance with the paper cutting position of the paper feeding path, and retracting the cutter mounting rod from the paper feeding path. a biasing means that is slidably attached to the cutter mounting rod and moves the cutter mounting lever against the urging force of the biasing means during a pressing operation so as to press the paper holding portion against the paper. A paper cutting mechanism comprising: a cutter that is brought into pressure contact with the paper feeding path via a cutter and that cuts the paper by a sliding operation with a blade entering the paper cutting position.
