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).

摘要： A line head includes a nozzle plate, a frame-shaped outer frame, a plurality of head chips, and a head support member arranged within the outer frame. The linear expansion coefficients of the nozzle plate and the head support member are larger than that of the outer frame. The nozzle plate is joined onto the outer frame and a tensile stress is produced in the nozzle plate by the outer frame. The head support member is joined and fitted with the outer frame. When the head support member thermally expands relative to the outer frame, a compression stress is produced in the head support member while a strain of the head support member is restricted by the outer frame.
