ABSTRACT:
According to detection results obtained by a plurality of printing medium detection device, a printing medium is carried in while controlling an operation of pressing a pinch roller to be in contact with a conveying roller and of separating the pinch roller from the conveying roller and an operation of pressing a spur to be in contact with a eject roller and of separating the spur from the eject roller. Accordingly, it is made possible to carry the printing medium into the apparatus in a proper state even when the printing medium is a nonstandard-sized printing medium. Moreover, while effectively utilizing one driving source, a plurality of mechanism is independently controlled. Hence, accurately controlled flat-pass printing can be realized despite of the relatively small number of components.
