    • In an optical scanning device 1, a housing 3 has a space 3a in the inside thereof. A floating rotational plate 2 is housed in the space 3a, and is caused to float and to rotate by a magnetic force. The floating rotational plate 2 has an optical deflection layer 6 thereon. A diffraction grating 71 is formed on the optical deflection layer 6 on and around the center axis Z of the floating rotational plate 2. When a beam of light falls incident on the diffraction grating 71 in a direction normal to the surface of the optical deflection layer 6, the diffraction grating 71 diffracts the light in a radius direction of the circular-shaped floating rotational plate 2. The light is transmitted through optical waveguides 20 and 51 to be emitted outside from the housing 3. By rotating the small-sized floating rotational plate 2 at a high speed inside the housing 3, it is possible to scan the light at a high speed and with a high resolution.
    • 在光学扫描装置1中,壳体3的内部具有空间3a。 浮动旋转板2容纳在空间3a中,并通过磁力而浮起并旋转。 浮动旋转板2上具有光学偏转层6。 衍射光栅71形成在浮动旋转板2的中心轴线Z上和周围的光学偏转层6上。 当光束沿垂直于光偏转层6表面的方向入射到衍射光栅71上时,衍射光栅71沿圆形浮动旋转板2的半径方向衍射光。 光通过光波导20和51传输,从外壳3发射出去。 通过使小型浮动旋转板2在壳体3内部高速旋转,可以高速,高分辨率地扫描光。

    • Connector housings (11, 12) to be mounted on a printed circuit board (100) have a plurality of rows of contacts (13, 14) extending from wall surfaces of the housing (11, 12). These contacts (13, 14) are soldered to conductive pads (23) of a flexible circuit (20). The flexible circuit (20), bent in a generally U-shaped, about an insertion portion (31) of a metallic guide portion (30) which is to be inserted between rows of contacts (50) of a mating connector (40) for interconnection therebetween. The guide member (30) preferably engages a ground conductor (176) on the reverse surface of the flexible substrate and includes extending portions (142) to groundingly engage conductive member (43, 124) positioned at both ends of the housing. In an alternate embodiment strengthening plates may be adhered to the flexible circuit between the opposed arrays of conductive pads and ground contact pads.
