发明名称 Print head
摘要 A print head for a line printer in which errors between print head chips and another component are reduced and ink leakage is prevented, and in which heat generated in print head chips is efficiently dissipated without making the structure of the print head complex or increasing the size of the print head. A plurality of print head chips ( 11 ) are arranged along an ink path ( 20 ) and are disposed on both sides of the ink path in a zigzag pattern. Dummy chips ( 21 ) which do not eject ink are disposed at regions between the print head chips ( 11 ) arranged along the ink path ( 20 ). In addition, an ink-path member ( 23 ) is provided, at least a part of the ink-path member ( 23 ) which includes portions adhered to the print head chips ( 11 ) being composed of a material having a high thermal conductivity, so that the ink-path member ( 23 ) also serves as heat-dissipating means which dissipates heat generated in the print head chips ( 11 ).
