Positioning mechanism for heat-sensitive recorder

Abstract

Abstract PURPOSE: To unnecessitate the adjustment of the positioning of a head utilizing a simple structure by a method wherein the head is supported elastically and is provided with a guide groove which engages the shaft of a roller. CONSTITUTION: A thermal head 27 supported elastically on the frame 24 of a recorder through a coil spring 28 has riser postions 42 on both sides in the longitudinal direction of its base 32. Each of riser portions 45 is provided with a U-shaped groove 43 which engages the metal 31 provided at either end of the shaft of a pressure roller 26. The centers of the guide grooves 43 are in register with that of a heating resistor 41. When the frame 24 is reclosed after the installation of a recording paper 30 and the cleaning of the head 27 are finished under the condition where a rock lever 35 is released and the frame 24 is opened, the head 27 adn the pressure roller 26 are automatically brought into coincidence and into mutual contact under an adequate pressure at the engaging position of the lock lever 35.
