In addition, incident light quantity regulator 220 comprises first tube stand 222, second tube stand 224 and tube stand rotational structure 226, and wherein first tube stand 222 and second tube stand 224 are in order to fixing two light source 210a, 210b.And, have a tube stand among first tube stand 222 and second tube stand 224 at least for adjusting.Being all the tube stand that can adjust with first tube stand 222 and second tube stand 224 in the present embodiment is that example describes.In addition, these tube stands that can adjust 222,224 are articulated in respectively on the tube stand rotational structure 226, in order to adjust the light quantity in the above-mentioned zone 82 of overlapping.
In the above-mentioned adjustable light source module 200, tube stand rotational structure 226 for example comprises main support 226a and control panel 226b.Wherein, main support 226a is fixed on the scanning optics, and is connected to the two ends of first tube stand 222 and second tube stand 224.And main support 226a for example is provided with groove 227 with respect to the above-mentioned tube stand of adjusting 222,224.In addition, control panel 226b is disposed in this groove 227, and can move in groove 227, so that the above-mentioned tube stand of adjusting 222,224 rotates by the relative displacement of control panel 226b.
In a preferred embodiment of the present invention, main support 226a for example has more slotted eye 228 and is revealed between first tube stand 222 and second tube stand 224, and can and be incident in the scanning optics by this slotted eye 228 from the segment beam (not expressing among the figure) of above-mentioned zone 82 reflections of overlapping.In addition, control panel 226b is displaced among the groove 227 by adjusting screw 232.But this adjust screw 232 for example snap close on main support 226a, and adjust screw 232 for example by the fixing control panel 226b of location clasp 234.In addition, control panel 226b for example has pilot hole 236, and the above-mentioned tube stand of adjusting 222,224 for example has register pin 228 accordingly, is inserted in the pilot hole 236 also can move along pilot hole 236, so that 222,224 rotations of the above-mentioned tube stand of adjusting.
Fig. 5 A and Fig. 5 B are the illustrative view of the described adjustable light source module of first embodiment of the invention.Please be simultaneously with reference to Fig. 5 A and Fig. 5 B, at first, shown in Fig. 5 A, control panel 226b is disposed in the groove 227 movably in the present embodiment, so that the tube stand 222,224 that can adjust rotates an angle θ 1 by the relative displacement of control panel 226b.In more detail, for example control panel 226b is displaced among the groove 227 in the present embodiment by adjusting screw 232.When 232 rotations of adjustment screw make progress, control panel 226b can move up along groove 227, pilot hole 236 is and then moved up, and drive register pin 258 and move, and then make the tube stand 222,224 that to adjust rotate an angle θ 1 to the central shaft 229 of main support 226a along the central shaft 229 of pilot hole 236 to main support 226a.
Then, shown in Fig. 5 B, when adjustment screw 232 continued to rotate upwards, control panel 226b can continue to move up along groove 227, and makes pilot hole 236 and then continue to move up.This moment, register pin 238 meetings were further moved to the central shaft 229 of main support 226a, and the tube stand 222,224 that can adjust can become big to the angle of central shaft 229 rotations of main support 226a.It should be noted that in the present embodiment the tube stand 222,224 that can adjust for example is 30 degree to the maximum angle θ 2 of central shaft 229 rotations of main support 226a.And in the case, the light quantity in light beam 212a, the 212b zone 82 of overlapping on sweep object 80 can be maximum.
Please be simultaneously with reference to Fig. 3 B and Fig. 5 B, below will be at before and after adjustable light source module 200 starts, the light quantity variation in light beam 212a, the 212b zone 82 of overlapping on sweep object 80 describes.Please earlier with reference to Fig. 3 B, as yet not before the start, the distance that light beam 212a, the 212b that two light source 210a, 210b sent is passed to the zone 82 of overlapping on the sweep object 80 for example is d1 at adjustable light source module 200.Then, please refer to Fig. 5 B, after adjustable light source module 200 starts, the distance that light beam 212a, the 212b that two light source 210a, 210b are sent is passed to the zone 82 of overlapping on the sweep object 80 for example can shorten to d2.
From the above, since non-parallel light in a unit area incident light quantity and light source so far the square distance of unit area be inversely proportional to.And before and after adjustable light source module 200 starts, light beam 212a, 212b shorten into d2 from the distance that two light source 210a, 210b are passed to the zone 82 of overlapping on the sweep object 80 by d1, can increase so be incident upon the light quantity in the zone 82 of overlapping on the sweep object 80 in the same units area.And in the same units area from above-mentioned overlap the zone 82 the reflection light quantity of incident photo-sensitive cell (not expressing among the figure) also can and then increase by slotted eye 228 (as shown in Figure 3A).Therefore, known scanner (not expressing among the figure) is when high-velocity scanning, and often the deficiency in light quantity because of the incident photo-sensitive cell causes picture quality not good shortcoming can be improved.
It should be noted that, in a preferred embodiment of the present invention, though being adjustable tube stand with first tube stand and second tube stand is example, yet it is not all to be required to be the tube stand that can adjust in order to all tube stands that limit in the adjustable light source module.In other words, but the tube stand of adjusting in the present embodiment also instrument be first tube stand or second tube stand one of them.
In sum, the present invention's adjustable light source module is because of adopting incident light quantity regulator, and moving by control panel in the adjustment screw control incident light quantity regulator, so that register pin moves along the pilot hole of control panel, and then first tube stand and second tube stand rotated an angle, increase the two light beams that scans on the object overlap the zone light quantity, the segment beam of regional reflex and incident photo-sensitive cell so that overlap certainly can provide photo-sensitive cell more light quantity.Therefore, the present invention's adjustable light source module can improve scanning optics when scanning at a high speed, and often the deficiency in light quantity because of the incident photo-sensitive cell causes the not good shortcoming of picture quality.
Though the present invention with preferred embodiment openly as above; right its is not in order to limit the present invention; the ordinary skill of any technical field that the present invention belongs to; without departing from the spirit and scope of the invention; when can doing a little change and improvement, so the present invention's protection domain is as the criterion when looking claims person of defining.
