Liquid discharge recording head

A liquid discharge head comprising:

• a liquid discharge unit on a surface of which a liquid discharge port for discharging liquid is provided;
• a liquid storing unit for storing liquid supplied to said liquid discharge unit, said liquid storing unit being connected to said liquid discharge unit from a side opposite to said surface;
• a first coupling mechanism for coupling said liquid discharge unit and said liquid storing unit upon an engagement movement in a coupling direction of said liquid discharge unit and said liquid storing unit, said first coupling mechanism having a first snap fitting provided on one of said units and extending in the coupling direction and a first receiving portion provided on another of said units, and upon engagement of said units, a slanted surface provided on said first receiving portion elastically deforms said first snap fitting in a direction different from the coupling direction so as to couple a hook-like portion of said first snap fitting with said first receiving portion;
• and
• a second coupling mechanism for coupling said liquid discharge unit and said liquid storing unit upon the engagement movement in the coupling direction of said units, said second coupling mechanism having a second snap fitting provided on one of said units and extending in a direction perpendicular to the coupling direction and a second receiving portion provided on another of said units, and upon the engagement of said units, a slanted surface provided on said second receiving portion elastically deforms said second snap fitting in a direction different from the coupling direction so as to couple a hook-like portion of said second snap fitting with said second receiving portion.
