Claims
- 1. A liquid ejection recording head removably mountable on a storage tank for storing liquid therein, the head comprising:
- means defining an orifice for discharging the liquid therethrough;
- a liquid chamber communicating with said orifice;
- an energy generating member for generating energy for forming droplets of the liquid;
- a base plate having a first portion on which said liquid chamber and said energy generating member are provided; and
- needle-type liquid supply pipes for insertion into the storage tank, said liquid supply pipes being arranged at opposite sides of said energy generating member such that said energy generating member is disposed generally between said liquid supply pipes and thus can be fed liquid from opposite sides thereby, wherein said liquid supply pipes project away from another portion of said base plate opposite said liquid chamber to supply the liquid from the storage tank to said liquid chamber and said energy generating member, and wherein said recording head discharges droplets in a direction transverse to that of liquid conveyance to said energy generating member from said liquid supply pipes.
- 2. A liquid ejection recording apparatus comprising:
- means defining an orifice for discharging the liquid therethrough;
- a liquid chamber communicating with said orifice;
- an energy generating member for generating energy for forming droplets of the liquid;
- a base plate having a first portion on which said liquid chamber and said energy generating member are provided;
- a storage tank for storing liquid therein; and
- needle-type liquid supply pipes removably inserted into said storage tank, said liquid supply pipes being arranged at opposite sides of said energy generating member such that said energy generating member is disposed generally between said liquid supply pipes and thus can be fed liquid from opposite sides thereby, wherein said liquid supply pipes project away from another portion of said base plate opposite said liquid chamber to supply the liquid from said storage tank to said liquid chamber to supply the liquid from said storage tank to said liquid chamber and said energy generating member, and wherein said recording head discharges droplets in a direction transverse to that of liquid conveyance to said energy generating member from said liquid supply pipes.
- 3. A device according to claim 1 or 2, wherein flow path walls for forming a flow path corresponding to said orifice are arranged in said liquid chamber.
- 4. A device according to claim 1 or 2, wherein said energy generating member comprises an electrical-thermal converter.
- 5. A device according to claim 1 or 2, wherein said liquid supply pipes communicate with the storage tank through holes therein.
- 6. A device according to claim 5, wherein said holes have sealing rings mounted therein.
- 7. A device according to claim 1 or 2, wherein said energy generating member generates thermal energy.
- 8. A device according to claim 1 or 2, wherein said energy generating member generates thermal energy.
