Use Figure 11～Figure 15 that the second execution mode of the present invention is described.Figure 11 is the major part profile of the scanning means of present embodiment.The optical system 52 of the first execution mode as shown in Figure 5.It is different that the scanning means A2 of present embodiment possesses on reflection part 526 this point scanning means A1 from the first execution mode in optical system 52.The structure of scanning means A2 is except camera 5, identical with the structure of the scanning means A1 of the first execution mode.
In the present embodiment, substrate 4 is equipped on the sidewall sections of base end part 21.Camera 5 possesses capturing element 51, optical system 52 and support 53.
Figure 12 is that major part along the XII-XII line of Figure 11 is to view.Figure 13 is the figure of read range of original copy Dc in the scanning means of expression present embodiment.Figure 14 is the major part plane graph of capturing element 51.Figure 15 is the major part enlarged drawing of Figure 14.In addition, in Figure 12, for convenient, optical system 52 and support 53 have been omitted.
Such as Figure 12, shown in Figure 14, capturing element 51 has the sensitive surface 511 of rectangle.The size of sensitive surface 511 for example is vertical 5.8mm, horizontal about 7.7mm.Such as Figure 14, shown in Figure 15, on sensitive surface 511 with the unit light area 512 of a plurality of rectangles of rectangular configuration.Constituent parts light area 512 is that the limit is at the rectangle of direction x and direction y extension.The arrangement pitches p1 of the unit light area 512 on the direction x for example is about 4.5 μ m.Arrangement pitches p1 is slightly larger than the size w1 of the direction x of constituent parts light area 512.The arrangement pitches p2 of the unit light area 512 among the direction y for example is about 8 μ m.Arrangement pitches p2 is slightly larger than the size w2 of the direction y of constituent parts light area 512.In the present embodiment, dispose 1280 * 960 unit light areas 512 at sensitive surface 511.Thus, capturing element 51 can read with the resolution of 265DPI the original copy Dc of L version size.
As shown in figure 11, optical system 52 possesses lens 525 and reflection part 526.Lens 525 remain on the support 53.Lens 525 make the light imaging on the sensitive surface 511 of capturing element 51 from the incident of original copy Dc side.In the present embodiment, lens 525 are that for example the visual angle is so-called standard lens about 50 °.
As shown in figure 11, reflection part 526 is installed on base end part 21.Reflection part 526 for example is made of aluminium.Reflection part 526 has the reflecting surface 526a that is made of the high minute surface of reflectivity.Reflecting surface 526a is positioned at the front of lens 525.Reflecting surface 526a is the aspheric surface of convex.More specifically, as shown in figure 13, its direction of reflecting surface 526a z distances upper and lens 525 are more larger towards original copy Dc side on direction x, and constant on direction y.Namely, reflecting surface 526a is to the convex surface of lens 525 side bulgings on direction x.In addition, the reflecting surface 526a that is consisted of by convex surface along with from lens 525 away from and curvature diminishes.By such structure, reflection part 526 makes it towards lens 525 by the light of reflecting surface 526a reflection from original copy Dc incident.
