| 主权项 | 1. A printer, comprising: a frame that includes a frame back part; an arm that includes a rotation shaft and is supported by the frame to rotate around the rotation shaft relative to the frame; a platen roller that includes a bearing rotatably supported by the frame or the arm; a print head that is disposed between the frame back part and the platen roller and performs printing on a recording sheet placed between the platen roller and the print head; and a first bias spring that is disposed between the frame back part and the print head and biases the print head toward the platen roller relative to the frame back part, wherein the frame includes a frame opening whose first edge is in contact with the bearing on a first side that is across the bearing from a second side where the print head is provided; and the first edge of the frame opening extends parallel to a first line connecting the rotation shaft of the arm and a center of the bearing of the platen roller. | ||
