Abstract:
A simplified image sensor module includes a substrate, a photosensitive chip, a plurality of wires, and transparent glue. The substrate has an upper surface formed with a plurality of first connection points, and a lower surface formed with a plurality of second connection points. The photosensitive chip has a plurality of bonding pads and is mounted to the upper surface of the substrate. The wires electrically connect the bonding pads of the photosensitive chip to the first connection points of the substrate, respectively. The transparent glue is arranged on the upper surface of the substrate to encapsulate the photosensitive chip and is formed with a convex portion corresponding to the photosensitive chip. The photosensitive chip may receive focused optical signals focused by the convex portion of the transparent glue.

Abstract:
An optical scanning device includes a light source, an optical system, and a housing. The light source projects a light beam. The housing includes a holder and encloses the optical system. The optical system includes a liquid crystal element held by the housing via the holder, to modulate a phase of the light beam projected from the light source against a scanned surface. The liquid crystal element includes a plurality of substantially transparent substrates, a liquid crystal layer, and a sealing member. One of the plurality of the transparent substrates has a size larger than any other transparent substrates and is positioned in the holder. The liquid crystal layer is sandwiched between the plurality of substantially transparent substrates. The sealing member seals the liquid crystal layer between the plurality of substantially transparent substrates.

Abstract:
The present invention is made to provide a fixing structure for solid state image forming device made inexpensively and easily by simple caulking adhering method with keeping high positional accuracy, by which it is achieved that the solid state image forming device can be separated easily from the image focusing lens holding member when the image focusing lens holding member has a defect. In the fixing structure of present invention, an image focusing lens holding member 3 and an intermediate holding member 6 are adhered by caulking adhering method. Because one or more projecting portion 3c for painting adhesive material formed on the image focusing lens holding member 3, have smaller area than that of bottom surface 6a of the intermediate holding member 6, a space 10 is formed between the image focusing lens holding member 3 and the intermediate holding member 6, the solid state image forming device 1 fixed on the intermediate holding member 6 can be easily separated from the image focusing lens holding member 3 by inserting and turning a tool 11 whose width of top portion is smaller than the width of space 10.
