RD-6517 STACKED BLADE MATRIX PRINTER HEADS Abstract of the Disclosure A printer head for use in an impact printer of the dot- matrix type utilizes a stack of pivoted thin blades, each having a printing tip at one end thereof. A pancake coil is attached to each blade for initiating selective independent movement thereof within a common, externally- produced magnetic field to efficiently convert electrical print signals to kinetic energy in each printing of vertical array thereof thereby facilitating printing of symbols, characters and other indicia on underlying media with high resolution. The single magnetic-field-producing means interacts with all pancake coils of the stack of printer blades to facilitate close spacing of the printing tips for superior character printing. Resilient members are integrally formed in each blade to support the moving structure with negligible loss, thereby increasing the printing speed of the stacked blade head.
