Printer

A printer that performs printing for a glass plate provided with a print region and used for a preparation slide, the printer comprising:

• a conveying unit that includes a plurality of paired rollers adapted to sandwich both side faces of the plate in a width direction orthogonal to a conveyance direction of the plate, brings the paired rollers respectively in contact with the both side faces of the sandwiched plate by urging each of the paired rollers with an urging force of an elastic member, and conveys the plate in the conveyance direction by the plurality of the paired rollers while sandwiching the plate by rotating each of the paired rollers with a driving force of a drive motor;
• a printing unit that includes a printhead and a swinging unit adapted to swing the printhead between a printing position and a retracting position apart from the printing position, shifts the printhead to the printing position by the swinging unit when printing, brings the printhead in contact with the print region on the surface of the plate being conveyed by the conveying unit, and performs printing for the print region by the printhead;
• and
• a suppressing guide unit that regulates floating-up of the plate when printing by coming in contact with the plate from a surface side only on a neighborhood region of the side face so as not to come in contact with an observation region at a center in the width direction of the plate on a surface of the plate being conveyed by the conveying unit;
• wherein the suppressing guide unit includes one pair of plate members disposed on the both side-faces of the plate.
