摘要： A liquid container which can precisely detects existence/absence of residual liquid at a low cost, a cartridge including the liquid container, and a printing apparatus using the cartridge. The lengthwise direction of a triangular prism provided on the bottom of the ink tank is along a direction of print medium conveyance in the printing apparatus, such that when an ink-jet head cartridge holding the ink tank is attached to the printing apparatus for performing printing, light emitted from an optical unit of the printing apparatus is precisely captured by the prism. Further, if two ink-jet head cartridges are mounted on the printing apparatus, the first and second ink-jet head cartridges are set in positions shifted from each other by a length shorter than the length in the lengthwise direction of the prism, such that the light emitted from the optical unit reaches the prisms provided in the ink tanks of the first and second ink-jet head cartridges.

摘要： A flow path forming member is formed with a recessed portion for forming an ink flow path. A junction surface of the flow path forming member is in a protruded state from a non-junction surface. The flow path forming member is composed of a transparent resin exhibiting transmissivity of laser beam. A tank holder is composed of a non-transmissive resin having no transmissivity of the laser beam. In a state where the flow path forming member is press-connected to the tank holder, the junction surface is welded by irradiating a periphery of the ink flow path with the laser beam from the side of the flow path forming member, thereby forming an ink flow path. Provided is an ink jet recording head in which the tank holder and the flow path forming member that serve to form the ink flow path are surely connected by a small number of steps without producing foreign matters within the ink flow path.

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： An ink tank having a negative pressure generating member for retaining ink, a case for accommodating the negative pressure generating member, the case having an atmosphere communicating portion held in communication with the atmosphere and an ink supply portion through which the ink is led out to the exterior, and an ink holding member disposed near the ink supply portion and developing a higher capillary action than the negative pressure generating member, wherein a recess is formed in an inner surface of a side wall of the case adjacent to a wall provided with the ink supply portion, the recess extending in a direction from the side of a wall opposing the wall provided with the ink supply portion toward the ink supply portion. Alternatively, in an ink tank having no ink holding member, at least a part of inner surfaces of the case is subjected to pear-skin treatment. With those ink tanks, a satisfactory ink supply ability is obtained while achieving a reduction of the tank size.

摘要： A magnetic disc has a magnetic recording area on or from which the information may be recorded or reproduced by a recording head loaded on a slider. The magnetic recording area has a data area including a recording track as a crest and a guard band as a valley, and a servo area having servo marks as crests and valleys. A CSS area for contact-start-stop (CSS) with the slider is made up of CSS data areas radially consecutive to the data areas and CSS servo areas radially consecutive to the servo areas. The entire surfaces of the CSS servo areas may be planarized at the same height level as the recording tracks. The CSS servo areas are provided with the same pattern of crests and valleys similar to that of the data areas. This suppresses generation of powder debris during CSS while optimizing the amount of float of the slider and the floating posture in the CSS area.
