摘要： A liquid storing container attachable and detachable to and from a recording device includes a negative pressure producing member storage chamber which has a bottom wall and opposed side walls and which accommodates a negative pressure producing member and is equipped with a liquid supplying section in the bottom wall and an atmosphere communication section. A partition wall separates the negative pressure producing member storage chamber from a liquid storage chamber and defines a communicating hole for establishing communication therebetween. A path in the vicinity of the communicating hole on the negative pressure producing member storage chamber side introduces the atmosphere from the negative pressure producing member storage chamber into the liquid storage chamber. The negative pressure producing member is made with a fiber material having directionality and the communication hole is offset from the bottom wall.

摘要： An ink jet recording head has a plurality of discharge energy generating devices for discharging recording liquid, while being provided with a recording element base plate arranged on the face opposite to the surface where the devices are arranged, having a plurality of recording liquid supply ports for supplying recording liquid to the devices, as well as with a supporting member that holds and fixes the recording element base plate. For the supporting member, a plurality of recording liquid supply paths are arranged to supply recording liquid to each of the supply ports of the recording element base plate, respectively, and then, the flow path width of each supply flow path is formed to be smaller than the opening width of inlet portion of each supply port. Further, the steps to be created between the supply flow path and the supply port is buried by the bonding agent forced out from the bonding face of the recording element base plate and the supporting member. With the structure thus arranged, the ink jet recording head is capable of optimizing the discharge characteristics of recording liquid and the supply characteristics thereof, as well as the positioning precision of a recording element base plate to a supporting member.

摘要： A liquid storage tank having a compartment for accommodating a negative pressure generating member consisting of a fiber material, having a liquid supplying portion and a connecting portion with the atmosphere; a liquid storing compartment for storing liquid to be supplied to the negative pressure generating member, and having a connecting portion with the compartment for accommodating the negative pressure generating member and forming an almost closed space and a separating wall separating the compartment for accommodating the negative pressure generating member from the compartment for storing liquid and forming the connecting portion and an air importing portion for importing air from the compartment for accommodating the negative pressure generating member to the compartment for accommodating the liquid, formed in the vicinity of the connecting portion. The liquid storage tank has structure to suppress an unnecessary collapse in the negative pressure generating member in the vicinity of the air importing portion, such as concave portions on a wall opposite the separating wall in the compartment for accommodating the negative pressure generating member.
