Abstract
A printer includes 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 is 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.
Claims17
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 is 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.
A printer, comprising:
- a frame;
- 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 is rotatably supported by the arm or the frame;

- and
- a torsion coil spring that is wound around the rotation shaft,
- wherein a first end of the torsion coil spring is connected to the arm, and a second end of the torsion coil spring is in contact with the print head and presses the print head toward the platen roller.
A printer, comprising:
- a frame;
- an arm that is rotatably supported by the frame;
- a platen roller that is rotatably supported by the arm or the frame;
- a print head that performs printing on a recording sheet placed between the platen roller and the print head;
- and
- a plate spring that is connected to the arm,
