Abstract

A printer comprising a cutting device for cutting the recording paper with a clean, straight edge is achieved. The printer comprises a pair of separable cutting blades, a fixed blade 14 and a movable blade 9, disposed with the cutting edges thereof mutually opposed in a substantially facing relationship on opposite sides of the paper exit 15 from which the recording paper is ejected. The movable blade 9 contacts fixed blade 14 at a point, and is driven with a scissors-like sliding action across fixed blade 14 by means of movable blade drive 10. Fixed blade 14 is supported on an openable cover frame 8 by support member 16 with a certain amount of play. Movable blade 9 is housed inside cutter unit frame 11. The cover frame supporting the fixed blade can be displaced between a cutting position wherein the fixed blade and the movable blade are disposed in an adjacent, substantially facing relationship and a non-cutting position wherein the fixed blade and movable blade are disposed at a distance from one another.
