Abstract
An ink jet recording apparatus comprises an ink jet recording head with a plurality of recording elements for generating energy for discharging ink, a plurality of ink flow paths, a plurality of ink discharge ports for discharging ink, and a plurality of recording element substrates, and a cap member for capping the discharge ports. The plurality of recording element substrates, the thickness of one being different from that of the others, are arranged adjacent to each other on a substantially even flat plane, and the cap member is made capable of capping the discharge ports of the plurality of recording element bases plates altogether on the substantially even flat plane.
Claims15
An ink jet recording apparatus comprising:
- an ink jet recording head provided with a plurality of recording element substrates respectively having a plurality of recording elements for generating energy to be utilized for discharging ink, a plurality of flow paths for retaining ink to receive said energy, and a plurality of ink discharge ports for discharging ink;
- and
- a cap member for capping the discharge ports of said ink jet recording head, wherein
- among said plurality of recording element substrates, the thickness of one recording element substrate thereof is different from that of the other recording element substrate and said plurality of recording element substrates are arranged adjacent to each other on a substantially flat plane, and
- said cap member is capable of capping said discharge ports of said plurality of recording element substrates collectively on said substantially flat plane or on another substantially flat plane.
