A printer apparatus includes a frame, a printer head, a platen roller that is supported by the frame, a biasing member that is provided between the frame and the printer head and configured to exert force toward the platen roller, and an opening/closing arm supported by the frame to rotate and move about an arm rotation shaft. A contact part between the opening/closing arm and a platen bearing of the platen roller is positioned opposite from a side in which the printer head is provided with respect to a line that connects a center of the arm rotation shaft and a center of the platen bearing. |
