Abstract
In an ink jet recording device having an ink tank integrated type jet recording head and a carriage for mounting the head thereon, good electrical connection is obtained wherein the electrical pad of the connecting terminal of the recording head and the electrical pad of the connecting terminal of the carriage are connected to each other while rubbing against one another. Further, also by specifying the arrangement position of the positioning member, more accurate electrical conduction is effected and also breaking of the positioning member is prevented, thereby providing an ink jet recording device having high reliability in aspects of both recording and durability.
Claims13
An ink jet cartridge for use in a recording apparatus having a carriage upon which is mounted said ink jet cartridge, said carriage having a first electrical contact portion, said ink jet cartridge having a plurality of different surfaces including a front surface and a bottom surface, said ink jet cartridge comprising:
- a recording head having a discharge port for discharging an ink;
- a second electrical contact portion;
- and
- a center of rotation about which the recording head is rotated into a mounting position on the carriage, said center of rotation being provided at a position which is closer to said ink discharge port than said second electrical contact portion and said ink jet cartridge is mounted on said carriage by rotation about said center of rotation thereby causing said first and said second contact portions to rub together with relative lateral movement and an electrical connection to be made between said first and said second electrical contact portions, said second electrical contact portion and said ink discharge port being provided on said different surfaces of said ink jet cartridge,
- wherein said ink discharge port is provided on the front surface of said ink jet cartridge and said second electrical contact portion is provided on the bottom surface of said ink jet cartridge.
