Abstract
An opening thermal printer device comprising a stationary frame having a print head provided with a line of heater points and a moving frame that carries a backing roller for paper strip via the ends of an axle, and that moves relative to the stationary frame between a first relative position in which the roller has one of its generator lines in contact with the line of heater points of the head, and a second relative position in which the roller and the head are spaced apart from each other. The print head is fixed to the stationary frame and the device includes a holding mechanism for pressing the roller against the line of heater points when the frames are in the first relative position, the mechanism comprising respective hooks for receiving each of the ends of the axle of the roller, the hooks being slidably mounted on the stationary frame to move in a direction perpendicular to the line of heater points and being subject to the action of respective resilient return members directed towards the print head.
