Patent ID: 7059793

Claim:
A printer, comprising: a printing section printing on a printing paper fed continuously thereto; a cutting section arranged downstream of said printing section in a paper feeding direction, said cutting section comprising; a fixed blade and a movable blade which cooperate with each other to cut the printing paper, said fixed blade and said movable blade being shiftable relative to each other between a cooperative mutually-adjoining position and an uncooperative mutually-remote position, a power transmission mechanism transmitting the driving force of said drive source to said movable blade to move said movable blade, and wherein said power transmission mechanism includes a first gear train disposed on said first support member and connected with said drive source and a second gear train disposed on said second support member and connected with said movable blade, said first gear train being connected with said second gear train when said fixed blade and said movable blade are in said mutually-adjoining position, said first gear train being disconnected from said second gear train as said fixed blade and said movable blade are shifted from said mutually-adjoining position to said mutually-remote position, and an elastic member biasing said movable blade on said second support member toward a retraction position, and wherein said movable blade is operated for cutting by the driving force of said drive source against biasing force of said elastic member when said first gear train is connected with said second gear train, and is retracted into said retraction position under the biasing force of said elastic member when said first gear train is disconnected from said second gear train; a support mechanism supporting said printing section and said cutting section, said support mechanism including a first support member supporting said fixed blade of said cutting section and a second support member supporting said movable blade of said cutting section, said first support member being fixedly arranged to specify an operative printing point in said printing section and said second support member being shiftably arranged relative to said first support member; and a drive source provided in said cutting section generating a driving force to move said movable blade on said second support member, said drive source being mounted on said first support member.
