Further, in the ADF25 of this example, two sections of springs 49 have the 1st little position 101 of diameter and large the 2nd position 102 of diameter.On the other hand, sheet metal 48 is formed with the installing hole 108 that can insert the 1st position 101, the 2nd position 102 can not be inserted.
Thus, when clipping two sections of springs 49 with lid 11 and sheet metal 48, will give prominence to from sheet metal 48 as long as two sections of springs 49 to be inserted the 1st position 101 in installing hole 108.Therefore, as long as installing that two sections of springs 49 just can be formed can the structure of ground connection.Further, the location of two sections of springs 49 can easily be carried out.
Further, in the ADF25 of this example, use sheet metal 48 as electroconductive component.
Thus, due to electroconductive component can be formed thinly, therefore, it is possible to make lid 11 thinning, can the compact ADF25 of implementation structure.Further, because sheet metal processability is good, therefore corresponding with the ADF varied in size etc. easily.
Further, in the ADF25 of this example, lid 11 is formed with the Embedded Division 105 that can keep two sections of springs 49.
Thus, when two sections of springs 49 are clipped between lid 11 and sheet metal 48, two sections of springs 49 can be remained on Embedded Division 105.Therefore the position of two sections of springs 49 fixedly need not be kept it with finger etc., two sections of springs 49 can be easily installed.
Further, the image-scanning device 10 of this example has above-mentioned ADF25.
Thus, not only do not need the parts (screw etc.) for installation two sections of springs 49, and the trouble of installing these parts can be saved.Therefore, it is possible to reduce the manufacturing cost of image-scanning device 10.
