Title
(EN) WIRE DOT PRINTING HEAD
(FR) TETE D'IMPRESSION PAR POINTS
Abstract
(EN)
A spring charge type of wire dot printing head, wherein a plurality of pairs of cores each consisting of a front core (35) and a rear core (36) are arranged toroidally on a base plate (44) and coils (39, 40) are wound alternately on one of these paired cores. Accordingly, the inductance of the coil (39, 40) can be increased and the reduction of current and power consumption can be accomplished.
(FR)
L'invention se rapporte à une tête d'impression par points du type à chargement par ressort, dans laquelle plusieurs paires de tores, composées chacune d'un tore antérieur (35) et d'un tore postérieur (36), sont placées selon une disposition toroïdale sur une plaque de base (44) et des enroulements (39, 40) sont enroulés de façon alternée sur l'un des tores de chaque paire. En outre, l'inductance de l'enroulement (39, 40) peut être augmentée, ce qui permet d'obtenir une réduction de la consommation de courant et de puissance.
