    • A liquid ejection head includes a common-chamber formation member including a common chamber to supply liquid to pressure chambers communicating nozzles for ejecting liquid droplets, a flexible thin-film member to form part of a wall face of the common chamber, and a thin-film support member bonded to the thin-film member with glue. The support member has an opening or a recessed portion at least partially having a shape that is broad in an area proximal to a first surface of the support member bonded to the thin-film member and becomes narrower as an area of the opening or the recessed portion is more distant from the first surface. The opening or the recessed portion is sealed with the thin-film member. A portion of the thin-film member corresponding to the opening or the recessed portion has the glue on only a periphery area of the portion that contacts the support member.
    • 液体喷射头包括共用室形成构件,其包括公共室以将液体供应到用于喷射液滴的连通喷嘴的压力室,形成公共室的壁面的一部分的柔性薄膜构件, 薄膜支撑构件用胶粘在薄膜构件上。 支撑构件具有开口或凹部,该开口或凹部至少部分地具有在接近薄膜构件的支撑构件的第一表面附近的区域中宽的形状,并且作为开口的面积变窄或凹入 部分距离第一表面更远。 开口部或凹部用薄膜部件密封。 对应于开口或凹部的薄膜构件的一部分仅在与支撑构件接触的部分的周边区域上具有胶水。

    • A light-emitting element is mounted on a first conversion element mounting portion prepared on a lead frame and resin-molded by using a mold. In this case, a focusing lens whose optical axis coincides with the major surface of the light-emitting element and a coupling portion in which a sleeve is fitted are integrally molded at once to mold a transmission section and an electronic circuit section. When these member are fixed in housings, and a ferrule holding an optical fiber is inserted in the sleeve fitted in a recess portion of the coupling portion, the optical fiber is optically coupled to the major surface of the light-emitting element. At this time, when the distal end portion of the sleeve is brought into contact with the abutment portion in the coupling portion, the end face of the optical fiber always coincides with the major surface of the light-emitting element, thereby realizing reliable optical axis alignment.
    • 发光元件安装在通过使用模具进行树脂模制的引线框架上制备的第一转换元件安装部分上。 在这种情况下,其光轴与发光元件的主表面一致的聚焦透镜和其中装配有套筒的联接部分一体地模制成模制透射部分和电子电路部分。 当这些构件固定在壳体中时,并且将保持光纤的套圈插入装配在耦合部分的凹部中的套筒中,光纤被光耦合到发光元件的主表面。 此时,当套筒的前端部与接合部的抵接部接触时,光纤的端面总是与发光元件的主面重合,从而实现可靠的光轴 对准。
