PURPOSE: A device for transferring and guiding a paper of a printer for printing on both faces is provided to smoothly transfer papers along a transfer route by improving a structure. CONSTITUTION: In printing both faces, a paper of which one face is printed in a print unit is transferred toward a reversible rotary roller(41) via a reversal route(40). A blocking member(100) blocks an outlet of the reversal route. A front end of the paper is collided with a blocking lever(100) and comes out by being butted with the reversible rotary roller. The passage of a rear end of the paper is sensed by a second sensor, and the paper comes out of the reversal route. The blocking lever is rotated in a clockwise direction and blocks the output of the reverse route. Accordingly, when the paper enters a relay route(50) by the rotation of the reversible rotary roller, the paper enters the relay route by colliding with the blocking lever even if it faces the reversal route.
