This printing device performs positioning so that laser light (LB) from a laser light irradiation unit (33) installed on a paper-supplying section (3) is irradiated on a laser light detection unit (35) installed on an entrance unit (9). Being highly coherent, the laser light (LB) is propagated rectilinearly without being diffused. Consequently, precise positioning can be accomplished using optical positioning, which performs positioning so that the laser light (LB) can be irradiated. |
