PRINTER HEAD

摘要

A printer head of line printer in which ink leakage is prevented by reducing an error occurring between a printer head chip and other members, and heat generated from the printer head chip can be dissipated efficiently without complicating the structure of the printer head or increasing the size thereof. A plurality of printer head chips (11) are arranged zigzag along an ink channel (20) on the opposite sides thereof. A dummy chip (21) ejecting no ink is placed between the printer head chips (11) in the direction of the ink channel (20). Furthermore, an ink channel member (23) also serving as means for dissipating heat generated in the printer head chips (11) is provided by forming at least a part, including a part being boded to the printer head chips (11), of a material having a high thermal conductivity.
