M431516 V. New description: 【New technology field】 »*.V Year of the month! 1. Correction replacement page on the 17th of the thirteenth month. This creation is about the image sensing module, 4 is related to a contact type. ~ Contact Image Sensor Module (CISM). [Prior Art] When the front photocopying machine or the facsimile machine is in use, most of the contact image sensing modules are used as elements for sensing the to-be-scanned document for sensing such as text photos or pictures. These photocopiers or fax machines have a light-transmissive sweeping station, but

The touch image ❹m group is disposed below the (4) platform and coupled with the transmission mode group. When the photocopier or the fax machine scans a file to be scanned, the file to be scanned needs to be placed on the sweeping table first, and the money is driven by the driving module to scan the image of the image to be scanned. A preset scanning web; the contact image sensing module generates and outputs a result after sensing, that is, completes the scavenging work on the _ file. Referring to FIG. 1, the component of the conventional image sensing module 100 is not intended to be exploded. The structure mainly includes: a linear lens 2, a light source unit 18, and a casing H. When the above-mentioned components of the conventional image sensing module (10) are assembled, the light source unit 18 and the linear lens 2 are adhered and adhered to the housing 1G by the manual bonding method, and the light source unit 18 is The plurality of terminals 8 are penetrated under the casing ,, and the terminal 8 located under the casing 1G is bonded to the solder joints or through holes on the sensor substrate 12. When the conventional image sensing module is produced by such a combination, if the sensor is inadvertently, the sensor group on the sensor substrate 12 may be glued to reduce the manufacturing yield. If the quality is bad and heavy work is required, it is difficult to disassemble the individual components that have been bonded, and it is extremely easy to cause damage to the components, resulting in an increase in manufacturing cost. 3M431516

17曰Revision replacement page is to solve the above-mentioned shortcomings of the gluing method. The component is combined with the image sensing module. Point: Although it is another conventional method, it has the following defects in the manner of snapping. (1) It needs to be manually The snap-fit assembly is performed to make the assembly cost high. (2) A complex and corresponding hook structure must be formed between the snap-in components. Therefore, in the assembly, the tolerance between the components is often caused, resulting in defective products. (3) Because the complex hook structure of the small-sized mutual cooperation must be designed between the snap-in components, the mold development is relatively complicated, so that the manufacturing cost and maintenance cost of the mold are high, so the component manufacturing cost is high. (4) Due to the smallness and lightness of the combined card groove, it is often broken or damaged during the handling process, resulting in the failure to enter the manufacturing stage, that is, the occurrence of defective products, the cost of making and assembling parts is high and the maintenance is not easy. Therefore, I know that the combination of the image sensing module has disadvantages in terms of whether the glue sensing or the clamping method is used. Therefore, it is necessary to propose a solution to the assembly method of the image sensing module. '[New content] The purpose of this creation is to provide an image sensing module, which is structured to avoid the disadvantages of conventional assembly or manufacturing cost of the image sensing module, excessive defect caused by residual, and suitable for a large number of produce.

W] [Embodiment] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. Please refer to FIG. 2, which is a schematic diagram showing the explosion of the image sensing module U0 according to the first preferred embodiment of the present invention. The image sensing module (4) is suitable for M431516 101 g month 7 g correction replacement page contact image reading system to sense a target of a cat to be scanned, such as a document, the main name of the structure includes: · a linear lens 52, a first A light guide strip 53, a light source unit 68, a housing 60 and a sensor substrate 62 are shown in FIG. 2, the light source aquarium 68 is for providing linear light and further comprising at least one light source 56, a first Two light guiding strips 54 and a set of light source terminals 58. The at least one light source 56 provides light of at least one light source and is disposed on one of the shorter sides of the second light guiding strip 54. The second light guiding strip 54 guides the light of the spot light source into a linear light and faces the longer side of the second light guiding strip 54 to be incident on the first light guiding strip 53 (like the first Figure 3b). The light source terminal 58 is located below the light source unit 68 for electrically connecting the at least one light source 56 as a power source for driving the light source 56. In the preferred embodiment, the at least one light source 56 includes a plurality of light sources. Because of the uniformity of the light source, a plurality of light sources must be equidistantly arranged on the shorter side of the second light guiding strip 54. The light source of the light source faces the other shorter side of the second light guiding strip 54 to uniformly introduce the light emitted by each light source 56 into the second light guiding strip 54 to become a linear light. In Fig. 2, the first light guiding strip 53 has a cylindrical shape for changing the direction in which the linear light emitted from the light source 'single S 68' is changed. In the preferred embodiment, the first light guiding strip 53 is disposed adjacent to the longer side of the second light guiding strip 54 (as shown in FIG. 3b) for using the linear light. The transmission path of 1 is directed outside the first light guiding strip 53 in the direction of the linear lens 52. In the embodiment, the linear lens 52 has a T-shaped cross section for collecting the linear light emitted from the first light guiding strip 53 to face a target to be scanned outside the image sensing module. Shooting, and then sensing the target to be scanned. The "sensing the target to be scanned" means that the linear light of the image sensing module 110 is projected to the target U to be scanned, because the light projected on the target to be bounced is reflected, so that the image is sensed 6 M431516

ibJ • At the end of February π, the correction replacement page *·ι .1 The measurement module 110 receives the reflected light. It should be noted here that in other embodiments, the linear lens 52 may be a flat type, a cylindrical type, an irregular type linear lens or any shape of a linear lens capable of projecting a linear type of light onto a target. The spirit of creation.
