    • A disclosed printer includes a frame; a thermal head attached to the frame; a platen roller drive motor attached to the frame; a reduction gear train attached to the frame and configured to reduce the speed of rotation generated by the platen roller drive motor; and a platen roller detachably attached to the frame and configured to be driven by the platen roller drive motor via the reduction gear train and to feed paper while pressing the paper against the thermal head. The frame is produced by press-forming sheet metal and includes a horizontal plate part, a backboard part rising vertically from a back edge of the horizontal plate part, sideboard parts rising vertically from corresponding side edges of the horizontal plate part, and a projecting part protruding outward from an edge of one of the sideboard parts and forming a surrounding part of a gearbox.
