INK CARTRIDGE FOR BUBBLE JET TYPE PRINTER

摘要

PURPOSE: An ink cartridge of a bubble jet type printer is provided to rapidly emit heat from a print head chip by preventing a formation of bubbles through lowering a temperature of the print head chip. CONSTITUTION: An ink cartridge(100) includes a body section(140), and a bottom section(142), which is connected to the body section(140) and provided at a bottom surface(146) thereof with a print head chip(120). An edge of the print head chip(120) is bonded to the bottom surface(146) of the bottom section(142). A flexible printed circuit(130) is arranged around the print head chip(120). Electrode pads are connected to the flexible printed circuit(130) through wires. The wires are bonded to a lateral part(144) of the ink cartridge(100). The flexible printed circuit(130) is made of polymer material and formed at an inner portion thereof with conduits. The flexible printed circuit(130) is connected to a heater so as to emit heat generated from the heater.
