Abstract

서멀헤드의 프린터 본체의 프레임에 대한 유지를 원터치로 용이하게 행할 수가 있고, 더욱이 유지를 위한 특별한 부재를 필요로 하지 않는 서멀헤드의 유지기구 및 유지된 서멀헤드를 스프링에 의해서 플래튼측으로 균일하게 누를 수가 있으며, 더욱이 스프링을 장착한 헤드스프링 어셈블리의 탈착을 원터치로 행할 수 있는 서멀헤드의 누름기구를 제공하는 것을 목적으로 하고, 서멀헤드의 히트싱크부의 양단에 돌기를 형성하며, 또한 프레임을 서멀헤드를 프레임에 장착시에 그 돌기가 끼워져 들어가고, 또한 장착된 서멀헤드를 플래튼측으로 넘어뜨렸을 때, 상기 돌기의 탈락이 저지되는 걸림 구멍을 형성하며, 또한 헤드 스프링을 장착한 헤드 스프링 어셈블리에 돌출편 및 위치결정 구멍을 형성하고, 또한 프레임에는 상기 돌출편이 끼워져 들어가는 돌출편 받이 및 위치결정 구멍이 끼워 맞추어지는 돌기를 형성한다.One-touch holding of the thermal head to the frame of the printer main body can be easily performed, and further, the holding mechanism of the thermal head and the retained thermal head that do not require a special member for holding are evenly pressed to the platen side by a spring. It is also an object of the present invention to provide a thermal head pressing mechanism capable of detaching the spring-loaded head spring assembly with a single touch, and forming projections at both ends of the heat sink portion of the thermal head, and also providing the frame with the thermal head. The projection is inserted into the frame, and when the mounted thermal head is turned over to the platen side, it forms a catching hole in which the projection is prevented from falling off, and also protrudes into the head spring assembly to which the head spring is mounted. And a positioning hole, and the projecting piece is fitted into the frame. Projection piece forms a projection that is fitted into the socket, and the positioning hole.
