Embodiment 1

[0096] figure 1 is a schematic longitudinal sectional view of the basic structure of an example of the sensor module according to Embodiment 1 of the present invention. figure 2 is used for figure 1 Longitudinal cross-sectional view of an example of the basic structure of the housing components of the sensor module.

[0097] exist figure 1 Among them, the sensor module 10 according to Embodiment 1 is a sensor module having an internal moving part and an auto focus (AF) function. The sensor module 10 includes a dustproof housing part 1, a focus lens 2, a VCM (Voice Coil Motor) 3 serving as a driving part to vertically move the focus lens 2, a substrate 4, a solid-state image pickup chip 6 provided on the substrate 4, and an IR Cut-off filter 7. In addition, reference numeral 8 is a fixing part, which is a resin case, and reference numeral 9 is a furnishing case, which is an outer wall of an electronic information device (such as a mobile phone device).

Embodiment 2

[0111] In the above-mentioned embodiment 1, the opening diameter of the circular hole 13a of the light-shielding sheet 13 is set such that this diameter is smaller than the opening diameter of the circular hole 11a on the upper surface of the shell 11 (metal casing), and in addition , such that the diameter is set, no flare will be generated due to the lens characteristics of the focusing lens 2. In Embodiment 2, in addition to the above configuration, the inner peripheral side surface of the circular hole 13a of the light shielding sheet 13 is provided as a tapered surface so that the diameter can be reduced in the direction in which incident light enters.

[0112] image 3 is a longitudinal sectional view of an example basic structure of a case member for a sensor module according to Embodiment 2 of the present invention. Figure 4 Yes image 3 Plan view of the middle shell part. exist image 3 and Figure 4 , the same reference numerals refer to the figure 1 Those pa...

Embodiment 3

[0120] In Examples 1 and 2, a black adhesive sheet was used for the light-shielding sheet 13 or 13A. In Example 3, a color change will be added (patterned) to black on a black adhesive sheet (eg, light-shielding sheet 13B).

[0121] Figure 5 is a perspective view of an example basic structure of a case member for a sensor module according to Embodiment 3 of the present invention. Image 6 Yes Figure 5 Plan view of the middle shell part. exist Figure 5 and Image 6 , the same reference numerals refer to the figure 1 Parts with the same functions and effects as those in . in addition, figure 1 The structure of the sensor module 10 is also suitable for Figure 5 and Image 6 .

[0122] exist Figure 5 and Image 6 Among them, the dustproof case part 1B in the sensor module according to Embodiment 3 includes a case 11 covering a focusing lens 2, a VCM (Voice Coil Motor) 3, a solid-state image acquisition chip 6, and an IR cut filter 7 located thereon, and a substr...

Abstract

A case member has a predetermined surface and a sealable inside, where a first circular area for passing light is provided at the center portion of the predetermined surface, a double-sided light shielding sheet, which is provided with a second circular area for passing light at the center, is adhered to the predetermined surface such that the second circular area is positioned in a concentric circle manner to the first circular area, the second circular area having a diameter smaller than the diameter of the first circular area, a transparent dustproof film is adhered on the light shielding sheet.

Description

[0001] This non-provisional application claims priority under 35 U.S.C § 119(a) to Japanese Patent Application No. 2007-277008 filed on October 24, 2007, the entire contents of which are incorporated herein by reference. technical field [0002] The present invention relates to a sensor module equipped with a solid-state image acquisition chip for performing photoelectric conversion and acquiring image light from an object, a case member for the sensor module, and electronic information using the sensor module as an image input device in an image acquisition section Devices such as digital cameras (eg, digital video cameras and digital still cameras), image input cameras (eg, onboard cameras), scanners, fax machines, and camera-equipped cell phone devices. Background technique [0003] For this type of traditional module, the solid-state image acquisition chip is installed in a package, which includes epoxy resin and ceramic and glass substrates and shell parts such as plasti...
