A printer in which an end surface of a paper cutter having a sharp blade can be utilized as a paper carrying path by shunting the continuous sheet from the blade. The paper cutter is disposed in the carrying path of the continuous sheet. The paper cutter has a blade extending in a direction transverse to a carrying direction of the continuous sheet at its distal end. A conducting protrusion is formed on a part of the blade of the paper cutter along an extending direction of the blade. An outer periphery of the conducting protrusion, which contacts with the continuous sheet, has a cross section of a substantially circular arc.
