Abstract
A printer apparatus includes a print head, a platen roller having a rod, a spring configured to press the print head toward a direction of the platen roller, a frame having in a side face thereof a platen supporting groove for supporting the rod of the platen roller, and a detection switch, wherein the platen supporting groove includes a first edge situated toward a direction of the print head and a second edge situated opposite from the first edge, and has on the second edge a projection projecting toward inside the platen supporting groove, and wherein placing the rod of the platen roller at a predetermined position at a deeper side of the platen supporting groove than the projection causes the rod of the platen roller to press the detection switch due to an urging force that is applied to the platen roller by the spring through the print head.
