The difference is that the bottom of the light-emitting element 72 is the hemisphere, and the printed circuit board has a shape that matches the shape of the positioning = 728. A plurality of recessed holes 714, wherein the recessed holes 714 are also located on the area between each of the 犮 electrodes 712. With the positioning of the bottom of the light-emitting element, the starting point and position are on the printed circuit board 7 丨 〇. Please refer to Fig. 7B, which shows the bottom of a light-emitting element in Fig. 7A according to 9050twf.ptd Page 11 563348 V. Description of the invention (8) --- Schematic 'The positioning member 728 is a half sphere, and the positioning member can be packaged # 5 24 —Body forming. In order to make those skilled in the art better understand the present invention, please refer to FIGS. 8A to 8B, which shows the layout of the positioning element of the light-emitting element and the printed circuit with two recesses. As shown in FIG. 8A, when the light-emitting element When the positioning member 728 at the bottom is a cylindrical body, the positioning member 728 is the same as the positioning member described in the first embodiment, but the depth of the positioning member 728 is less than the thickness of the printed circuit board 71. In addition, the printed circuit board 710 is drilled and positioned. The depth of the piece 728 is equivalent to the hollow cylindrical recessed hole 714, so that the positioning member 728 and the recessed hole 71 4 can be tightly engaged; and when the positioning member 728 at the bottom of the light emitting element 720 is a half sphere, it is drilled on the printed circuit board 71 (). The hollow hemispherical recessed hole 71 4 (as shown in FIG. 8β), which is equivalent to the shape of the positioning member 728, enables the positioning member 728 and the recessed hole 714 to be tightly engaged, so that the light emitting element 7 2 0 can be more precisely positioned on the printed circuit. Board 7 丨 〇. However, those skilled in the art can change the positioning parts on the light-emitting elements, positioning holes ’and the recessed holes on the printed circuit board to convex points, which can also achieve the position of b. Please refer to Figures 9A ~ 9B for details. It shows the layout of the positioning of the light-emitting element and the bumps of the printed circuit board. The light-emitting element 9 2 0 has a positioning hole 928 at the bottom, and the printed circuit board 9 10 has a projection. Point 914, where the positioning member 9 2 8 at the bottom of the light-emitting element 9 2 0 is engaged with the bump 9 9 4 of the printed circuit board 9 1 0 can also accurately position the light-emitting element 9 20 on the printed circuit board 9 10. In summary, the light source module of a scanner of the present invention has at least the following advantages: 1. The light source module of the scanner of the present invention uses a positioning member or a positioning hole, which does not increase the difficulty in manufacturing the light-emitting element, which is extremely Practicality without increasing manufacturing costs.
