Abstract
An adjustable scanner module features that an assembly of an adjusting seat and a lens is arranged on the base of an optical unit, and an adjusting unit on said adjusting seat is combined with the assembly of image sensor set and its seat. The image sensor seat can move relatively to the adjusting seat, so the position of image sensor seat can be adjusted to unify the optical pathes of different colors in the image information obtain by image sensor.
Description
Technical field
The present invention relates to a kind of scan module, especially have the scan module that to adjust position of image sensor.
Background technology
See also Fig. 1, be disclosed as the light path synoptic diagram among the figure.After image information 11 in the general optical system refers to scanning, the light that scanned document 12 reflects.The total optical path of this image information 11 comprises stroke that image information 11 penetrates glass 13, at the reflection of 14,15,16 of the reflecting optics stroke of advancing, and through the stroke of lens 17 to 18 of image sensors.
Because the wavelength of the three primary colors (RGB) of light is to the refractive index difference of glass 13, and because the image sensor of RGB is not to be positioned on the same line, but have some differences, so the total optical path length of each coloured light in the image information 11 can be slightly variant.The total optical path of each coloured light differs bigger in image information 11, and then the color effect that is produced is just poorer.
Adjusting the position of this image sensor 18, is a kind of feasible method of revising the optical path difference of each coloured light.But the image sensor of many scanners 18 is to be cemented on the pedestal, and when cemented, this image sensor 18 is easy to generate skew or crooked situation, can't effectively reach the effect of revising light path.In addition, cemented means are inconvenient on the implementation.
Summary of the invention
One of purpose of the present invention provides a kind of adjustable scan module, and it can be by the assembling position of adjusting image sensor, and revises the optical path difference of each coloured light.
Two of purpose of the present invention provides a kind of adjustable scan module, its have can easy adjustment image sensor assembling position effect.
For reaching above-mentioned purpose, the present invention is provided with adjustment unit between adjustment pedestal and image sensor seat, and this adjustment unit can make this image sensor seat produce relative motion with adjusting pedestal, to reach the relative position of adjusting this image sensor seat and adjusting pedestal.

Embodiment
Figure 2 shows that the outside drawing of scan module.Fig. 3 is the exploded view of scan module.Fig. 4 is the combination synoptic diagram.Disclose this scan module among the figure respectively and include an optical base 21, an adjustment pedestal 31, lens 41, an image sensor seat 51, an image sensor 61 and two adjustment units 71.
The set accommodation space 22 of one end of this optical base 21 is assembled for this at least one scanning light source (not shown) and several reflecting optics 25-27.Wherein this scanning light source is in order to shining file to be scanned, and by the light that file to be scanned reflected, is defined as image information.This image information can be advanced between each reflecting optics in reflection in regular turn.
This optical base 21 also can not comprise light source, and in the case, light source is that the top from file penetrates file, and is received by optical base 21.
This adjusts pedestal 31, and group is located on this optical base 21, and these lens 41 can be organized and are located on this adjustment pedestal 31, and in order to receive the image information that reflecting optics reflected of this optical base 21, also can organize to be located on the optical base 21 and to adjusting pedestal 31.
It should be noted that this adjustment pedestal 31 can be one-body molded with this optical base 21.
This adjustment unit 71 is made into wing bulk, and offers slotted hole 72 on the surface of this adjustment unit 71.This slotted hole 72 can present arcuate shape.This adjustment unit 71 can extend from two sides of this adjustment pedestal 31 respectively, and this slotted hole 72 is adjusted pedestal 31 away from this.
51 pairs of this image sensor seats should be adjusted a side of pedestal 31 and away from these lens 41.It should be noted that this image sensor seat 51 and these adjustment unit 71 windings, and have a spacing 81 between this image sensor seat 51 and this adjustment pedestal 31.
The winding of this image sensor seat 51 and adjustment unit 71 is passed the slotted hole 72 of this adjustment unit 71 by a screw lock module 82, and these screw lock module 82 lockings fix on this image sensor seat 51 and reach.
This image sensor 61 is installed on this image sensor seat 51, the image information after focusing in order to receiver lens 41.
Fig. 5 and Fig. 6 are the adjustment view of this image sensor seat.This image sensor seat is located on this adjustment unit 71 for 51 groups, and this image sensor seat 51 combines for articulating with this adjustment unit 71, so unclamp this screw lock module 82, this image sensor seat 51 just can adjust upward, or adjusts downwards.
Promptly change the relative position of this image sensor 61 and these lens 41 after the adjustment, the optical path length that this moment, each coloured light after lens 41 focus on arrived this image sensor 61 has some variations, so just can make the light path of each coloured light in the image information more approaching, to obtain better scanning quality.
Because 71 of this image sensor seat 51 and adjustment units are combined by screw lock module 82, and the end of this screw lock module 82 can be made into and has bigger area with convenient rotation, so can conveniently carry out the adjustment of this image sensor seat 51 like this.
The above is preferred embodiment of the present invention and design, this embodiment and design only illustrate, be not to be used to limit the scope of the invention, all with the technological means that is equal to or any distortion in the scope that claim was contained, all do not break away from interest field of the present invention and category thereof.For example, adjustment unit 71 may extend on the image sensor seat 51, is positioned at the adjustment unit of adjusting pedestal 31 those ends this moment and is provided with slotted hole, and image sensor seat 51 is adjustably locked by screw lock module.
