摘要:
A recording apparatus using a recording head to effect recording on a recording material includes a recording head unit provided with a recording head for effecting recording on a recording material including a recording head supporting member for supporting the recording head at a predetermined position; a relaying electric contact member including a first electric contact member for external electric connection; a second electric contact for electrically connecting the first electric contact member with the recording head; and an electric current supplying device for supplying electric current to the first electric contact member.
摘要:
A container for containing printing liquid for supplying to an ink jet head for an ink jet recording apparatus. The container includes a first chamber containing negative pressure producing material and having an air vent communicating with ambient air and a supply port for supplying printing liquid to the ink jet head. The container also includes a second chamber communicating with the first chamber via a communication port and providing a printing liquid reservoir for the first chamber. The capillary force provided by the negative pressure producing material adjacent a wall extending from the communication port and decreasing in a direction perpendicular to and towards the wall at least adjacent a part of the communication port which is uppermost in use of the container.
摘要:
A liquid container for containing printing liquid for supplying to a recording head for an ink jet recording apparatus, the container includes a first chamber containing a negative pressure producing material and having a printing liquid supply port connectable to a recording head for allowing printing liquid to be supplied to the recording head and an air vent for allowing ambient air to enter the container, and a second chamber which provides a printing liquid reservoir for the first chamber and is substantially closed apart from a communication port communicating with the first chamber to allow the printing liquid to flow into the first chamber and to allow air to be introduced into the second chamber from the first chamber. The second chamber comprises a replaceable printing liquid chamber.
