Printer

A printer comprising:

• a conveying roller that conveys a print medium;
• a print head that conveys an ink ribbon tape along a conveyance direction of the print medium conveyed by the conveying roller, and that performs printing on the print medium;
• a tension applying section that is provided at an upstream side of the print head with respect to a conveyance direction of the ink ribbon tape, and that allows tension applied to a center region along a width direction of the ink ribbon tape to be higher than tension applied to both end regions of the ink ribbon tape;
• and
• a guide roller that is provided between the print head and the tension applying section at the upstream side of the print head with respect to the conveyance direction of the ink ribbon tape, and that applies tensile force to the ink ribbon tape outward along the width direction of the ink ribbon tape,
• wherein the tension applying section includes a most protruding part at a position facing the center region along the width direction of the ink ribbon tape,
• the guide roller includes:
• a roller member which rotates according to conveyance of the ink ribbon tape;
• and
• at least one spiral feeding groove which is formed on a circumferential surface of the roller member and which is formed along an axial direction of the roller member,
• the at least one feeding groove is formed at an outer side of a position facing the most protruding part, and
• the at least one feeding groove is not formed at a portion where the most protruding part faces the roller member.
