    • This invention provides a light-receiving package for flat-plate mounting which can make monitor reception sensitivity of an optical signal constant without increasing the size of a module.
      The light-receiving package for flat-plate mounting of the present invention is provided with a first subassembly 31 in which a photo diode 41 is fixed to a front surface of a retaining holder 42, a back surface of the retaining holder 42 is a flat surface capable of moving parallel on a plane parallel to a light-receiving surface of the photo diode 41 and a second subassembly 32 which has a rectangular U-shaped concave holder 43 for retaining the retaining holder 42, and a flat-plate base 44 disposed on a substrate 11 and in which a surface of the flat-plate base 44 that is mounted on the substrate 11 is a flat surface capable of moving parallel to a substrate surface, the rectangular U-shaped concave holder 43 and the flat-plate base 44 are fixed, at least one of surfaces of the concave holder 43 having a rectangular U-shape being a flat surface is a flat surface capable of moving parallel to the back surface of the retaining holder 42.
    • 本发明提供了一种用于平板安装的光接收封装,其可以使光信号的监视器接收灵敏度恒定,而不增加模块的尺寸。 本发明的用于平板安装的光接收封装设置有第一子组件31,其中光电二极管41固定到保持保持器42的前表面,保持保持器42的后表面是平的 表面能够平行于光二极管41的光接收表面平行的平面移动,第二子组件32具有用于保持保持器42的矩形U形凹形保持器43,以及设置有平板底座44 在基板11上,安装在基板11上的平板基座44的表面是能够平行于基板表面移动的平面的矩形U形凹形支架43和平板基座 44是固定的,具有平坦表面的矩形U形的凹形支架43中的至少一个表面是能够平行于保持夹持器42的后表面移动的平面。
