ABSTRACT:
A sheet passage is formed so as to extend from a sheet feed position via a printing position to a sheet delivery position, delivery rollers driven by a driving unit are disposed between the printing position and the sheet delivery position on the sheet passage, pressure rollers are disposed on one side of the sheet passage so as to be in contact respectively with the delivery rollers disposed on the other side of the sheet passage, a back sheet guide is disposed between the delivery rollers and the sheet delivery position, and a printed sheet delivered by the delivery rollers and guided by the back sheet guide is transferred to a printed sheet storage unit by sheet transfer arms. Thus, the time required to transfer the printed sheet from the delivery rollers to the printed sheet storage unit is extended so that the time between the delivery of the preceding sheet to the printed sheet storage unit and the delivery of the succeeding sheet to the printed sheet storage unit is extended to prevent the smearing of the preceding printed sheet previously stored in the printed sheet storage unit with the ink by the succeeding printed sheet.
