Patent

CA 2056950

A thermal print head includes a head circuit board, a flattened flexible member partially overlapped on the head circuit board for electrical connection thereto in a limited region which is sufficiently smaller in length than the head circuit board, and a pressure applying member for pressing the flexible member into contact with the head circuit board in the limited region. The pressure applying member is in the form of a plate spring having a presser portion which is elastically deformed for pressing the flexible member into contact with the head circuit board in the limited region by elastic restoring force of the spring. :

ne tête d'impression thermique comprend une plaquette de circuit de tête, un élément flexible aplati chevauchant partiellement la plaquette de circuit de tête pour y être connecté dans une zone limitée qui est suffisamment plus courte que la plaquette de circuit de tête, et un élément de pression pour assurer le contact de l'élément flexible avec la plaquette de circuit de tête dans la zone limitée. L'élément de pression se présente sous forme d'un ressort plat ayant une partie presseuse qui est déformée élastiquement pour assurer le contact de l'élément flexible avec la plaquette de circuit de tête dans la zone limitée au moyen de la force de reprise élastique du ressort.
