Abstract
The utility model relates to an improved structure for an optical mechanism of a scanner. The utility model is formed by the method that two groups of optical path reflection lens groups of image taking, two groups of imaging lens groups, and two groups of image sensors are arranged in a casing body of a mechanism of an optical pattern assembly, and the optical pattern assembly can be caused to provide scanning of high solution degree and low solution degree.
Description
The utility model is the creation of relevant scanister optical facilities, the improvement structure of the beam path of pick-up image and adapting device thereof in the especially relevant optical facilities.
Generally commonly using the scanister optical facilities, see also shown in Figure 1ly, is to be provided with projecting lamp 2 in housing 1 outside, and housing 1 top is provided with a breach 11; Housing 1 is provided with reflector group 31,32,33 and imaging lens group 34 and image sensor 35.Projecting lamp 2 is in order to shine contribution to be scanned, do the image strip 3 of part and inject reflector group 31,32,33 via breach 11, reflection through these catoptrons is sent to imaging lens group 34, be sent to image sensor 35 after the line focus imaging, optical image is converted to the image information, and this image sensor 35 can be charged coupled device (Charge Coupled Device CCD).Comprise this above-mentioned optics module of commonly using optical facilities, single Optical Resolution can only be provided, be called single-lens optics module.Twin-lens scanister as another, for example No. 342158 " two resolution transmission-types and reflective scanning mode device " those shown of TaiWan, China patent announcement must dispose complicated, accurate mechanism, could switch different Optical Resolutions.For functions of use that promotes single-lens optics module and the labyrinth of simplifying twin-lens optics module, so creation of the present utility model is arranged.
A purpose of the present utility model is providing a kind of improvement structure of scanister optical facilities.
Another purpose of the utility model is providing a kind of employing twin-lens to be contained in the same optics module, and the improvement structure of the scanister optical facilities of high and low resolution scanning is provided.
Other purposes of the present utility model do not need other optics switching mechanisms in that a kind of tool two groups of independence optical paths reflector group and image sensor are provided, and can switch the scanister optical facilities improvement structure of carrying out high and low resolution scanning according to need.
A kind of scanister optical facilities improvement of the utility model structure is characterized in that, wherein is to be provided with first reflector group, the first imaging lens group and first image sensor that matches in the optics module; And be provided with second reflector group, the second imaging lens group and second image sensor that match; Respectively image strip is converted to the image information.
Wherein the first imaging lens group has higher Optical Resolution than the second imaging lens group.
Wherein first image sensor has higher Optical Resolution than second image sensor.
Wherein first image sensor and second image sensor are charged coupled device (CCD).
End face tool one breach of optics module is wherein injected respectively on first reflector group and second reflector group in the optics module for first image strip and second image strip.
Wherein end face tool two breach of optics module are injected respectively on first reflector group and second reflector group from this two breach respectively for first image strip and second image strip.
Other purposes of the present utility model, effect and specific embodiment see also graphic being described in further detail below, wherein:
Fig. 1 is for commonly using scanister optical facilities synoptic diagram.
Fig. 2 is the utility model scanister optical facilities first embodiment synoptic diagram.
Fig. 3 is the utility model scanister optical facilities second embodiment synoptic diagram.
Structurally improved first embodiment of the utility model scanister optical facilities, seeing also shown in Figure 2ly, is that left side in the housing 1 of optics module and right side top is provided with first reflector group 41,42,43 alternately downwards and is provided with the first imaging lens group 44 and first image sensor 45 in the bottom on right side in regular turn; And left side in the housing 1 of optics module and top, right side are provided with second reflector group 51,52,53,54 alternately downwards and are provided with the second imaging lens group 56 and second image sensor 57 in regular turn in left bottom; Housing 1 end face one side is provided with a breach 11, and breach 11 outsides are provided with projecting lamp 2.Projecting lamp 2 shines on contribution, and contribution reflects first image strip 4 and second image strip 5 passes breach 11; First image strip 4 is sent to the first imaging lens group 44 via first reflector group 41,42,43, and images in first image sensor 45, is converted to the image information; Second image strip 5 is sent to the second imaging lens group 56 via second reflector group 51,52,53,54, and images in second image sensor 57, is converted to the image information.
Second embodiment of the present utility model sees also shown in Figure 3, be to be provided with two breach 11 and two projecting lamps 2 in housing 1 top face both sides, first and second image strip 4,5 is injected by two breach 11 respectively, via first and second reflector group, first and second imaging lens group 44,56 passes to first and second image sensor 45,57 and is converted to the image information respectively respectively.First and second image sensor 45,57 of the utility model is located on the relative edge of housing bottom.Via first and second imaging lens group 44,56 of selecting the high and low different optical resolution of tool for use, or first and second image sensor 45,57, and directly switch the scan-image information of selecting for use first or second image sensor 45,57 obtained according to need, can obtain the image information of the high and low different resolutions of tool.
The above person only is embodiment of the present utility model, and any utilization the utility model exposure technology is done and simply become different, modifies the scope of all not taking off the utility model technology contents.
The utility model in same optics module via newly-increased one group of catoptron, imaging lens and increase the scanning information that an image sensor can provide high and low two kinds of resolutions, its structure truly has differently with commonly using single-lens scanister optical facilities, and effect truly has the enhancement part; And the utility model is used fixed two groups of reflector group, imaging lens group and two image sensor, can obtain two groups of scan-image information simultaneously, and simple directly switching, select needed image information for use, and complexity, accurate optics switching mechanism must be set, more known twin-lens scanister has more simple structure, easy to manufacture, and can obtain the advantage of two groups of scan-image information etc. simultaneously.
In sum, the utility model should close in patent requirement, earnestly asks and grants quasi patent early.
