ABSTRACT:
The thermal printer of the invention comprises a frame, a print head tiltably mounted in the frame, and a spring carried by the frame and forming a member for urging the print head into its printing position, with a flexible sheet of conductors terminating at the print head. According to the first characteristic of the invention, the spring is made of an electrically conductive material and includes a finger for being received in a corresponding orifice of the frame, while a portion of the sheet carries a conductive eyelet through which the finger of the spring passes when the spring is received in the orifice of the frame, the spring thus pinching the eyelet against the frame.
