ABSTRACT:
A printer system containing an elastic endless sheet member which extends between roller members in front of a print head. The roller members are disposed so as to form a flat surface of the elastic endless sheet member in front of the print head in order to ensure clean printing. One of the roller members is connected to a paper feed motor so that a paper sheet is fed in front of the print head in the vertical direction in unison with the rotation of the elastic endless sheet member around the roller members.
