PROBLEM TO BE SOLVED: To achieve both of miniaturization of a printer and its cost reduction by using skillfully belt tensile force. SOLUTION: When a driving motor 42 is operated, a drive roller 43 is rotated. When paper (α) is sent to between the drive roller 43 and a pinch roller 472, the paper (α) is surely sent to a printable position with a printer head 1 without slipping on the driven roller 43 with the pinch roller 472. After end of printing on the paper (α), the driving motor 42 is operated. Since a discharge roller 44 is connected to the drive roller 43 via a timing belt 43, the discharge roller 44 is also rotated together with the drive roller 43. When the paper (α) is sent to between the discharge roller 44 and a gear roller 46, the paper (α) is sent to a paper discharge opening without being slipped on the discharge roller 44 with the gear roller 46. Since a slant guide face is formed to a shaft freely rotatably supporting hole of the discharge roller 44, the discharge roller 44 comes in contact with the gear roller 46 by being urged by a component of a tensile force of the timing belt 45.
