A printer comprises a paper holding section, a conveying section, a printing section and a buffer section. The buffer section, which is arranged at the downstream side of the paper conveying direction of the paper holding section and the upstream side of the paper conveying direction of the conveying section, extends in the width direction of the paper orthogonal to the paper conveying direction and has a propping member that is propped against the paper surface of paper and a pair of elastic support sections that are connected with the two ends of the propping member in the width direction and press the propping member on the paper surface of the paper using an elastic force, wherein the pair of elastic support sections are connected with the propping member in such a manner that each of the elastic support sections can act separately.
