Abstract
The scanner includes: a shell body having a transparent platform for placing the file to be scanned; a scanning module movably placed in the shell body and can be used for scanning the file placed on the transparent platform, which possesses a downside ligh source for irradiating the file on the transparent platform from downside and an image converter for converting the image of the file into the digital image; an upper cover which can be movably mounted on the shell body and an upside light source is mounted on the downside of the upper cover and a shielding article is movably mounted at the downside of the upper cover, to be used for shielding upside light source.
Description
The present invention relates to a kind of scanner, refer to a kind of platform-type scanner that is provided with upper and lower sides light source and movable upside light source shielding thing especially.
Please refer to the synoptic diagram of existing scanner 10 shown in Figure 1, this scanner 10 comprises a housing 12, and it has a transparent platform 14, is used for placing file to be scanned.Be positioned at the file on the transparent platform 14 because the light sources of scanner 10 itself are the downsides by transparent platform 14, therefore can only scan opaque file.Scan a transparent file as desire, egative film for example, the user just must use a Portable backlight 16 by on the transparent file that is pressed on the transparent platform 14, so that light can be by upside through transparent file and make scanner 10 can scan this transparent file.When using backlight 16, the user must plug in the plug of backlight 16, and the light sources in the scanner 10 must be closed and could begin to scan transparent file, and this is very inconvenient concerning the user.
Except above-mentioned backlight 16, general scanner manufacturer also can provide the dismountable loam cake that is provided with backlight to scan transparent file for the user usually.When the scanning transparent file, the user must pull down the loam cake that does not have backlight, refills the loam cake with backlight.Because the loam cake with backlight is heavier, and is provided with plug, so the action of dismounting relatively wastes time and energy, and if user often need scan transparent and opaque file simultaneously the time, the action of dismounting dress can make the scanning work very trouble that becomes.
Therefore, fundamental purpose of the present invention is to provide a kind of scanner that is provided with upper and lower sides light source and movable upside light source shielding thing, to solve the above problems.
The object of the present invention is achieved like this, and a kind of scanner promptly is provided, and it comprises: a housing, and it has a transparent platform that is used for placing file to be scanned; The one scan module, be located at the file that is used in the described housing scanning on the described transparent platform in a movable manner, it comprises that a usefulness cause downside shines the downside light source of the file on the described transparent platform, and an image converter that is used for the video conversion of described file is become digitized video; One loam cake is installed on the described housing in mobilizable mode; One upside light source is installed on the downside of described loam cake, and when described loam cake was placed on the described transparent platform, described upside light source shone file on the described transparent platform by upside; One veil is installed on the downside of described loam cake in mobilizable mode, is used for covering described upside light source; Wherein when described upside light source was covered by described veil, the document image that described image converter is accepted was produced by the light that described downside light source returns through shining described file back reflection; And when described upside light source was not covered by described veil, described downside light source can be closed, and the document image that described image converter is accepted is penetrated after shining described file by described upside light source and the light crossed is produced.
The advantage of apparatus of the present invention is, and is simple in structure, easy to operate, can easily and carry out the scanning of transparent and opaque file with saving time.
Below in conjunction with accompanying drawing, embodiments of the invention are described, wherein:
Fig. 1 is the synoptic diagram of existing scanner;
Fig. 2 is the synoptic diagram of scanner of the present invention;
Fig. 3 is along the cut-open view of tangent line 3-3 among Fig. 2;
Fig. 4 is the functional block diagram of scanner of the present invention;
Fig. 5 is another enforcement illustration of scanner of the present invention;
When Fig. 6 covers for the upside light source crested thing of scanner shown in Figure 5 along the cut-open view of tangent line 6-6.
Please refer to shown in Fig. 2 to 4, scanner 20 of the present invention comprises: a housing 22, its upside are provided with a transparent platform 24, are used for placing file to be scanned; One scan module 26, be located in a movable manner in the housing 22, be used for scanning the file on the transparent platform 24, it includes sidelight source 28 and is used for upwards shining file on the transparent platform 24, and an image converter 30 is used for the video conversion of this document is become digitized video; One loam cake 32 is installed on the upper end of housing 22 in rotating mode; One upside light source 34 is installed on the downside of loam cake 32, and it is the tabula rasa module of an approximate square, is used for shining the file on the transparent platform 24 downwards when loam cake 32 is placed on the transparent platform 24; And a veil 36, be installed on the downside of loam cake 32 removably, be used for covering upside light source 34.This veil 36 is opaque caps, be used for being sleeved on the upside light source 34, it includes a smooth back side 38, be used for file on the concora crush transparent platform 24, and this back side 38 also can be used to the scanning background as downside light source 28, to avoid because of upside light source 34 and the different image qualities that influence the reflective scanning mode gained of loam cake 32 both reflectivity.
This scanner 20 comprises in addition; One sensor 40 is positioned at an end of upside light source 34, is used for sensing veil 36 whether to have covered upside light source 34; And a control circuit 42, be located in the housing 22, and be electrically connected on scanning module 26, upside light source 34 and sensor 40.When control circuit 42 senses veil 36 when having covered upside light source 34 via sensor 40, control circuit 42 can cut out upside light source 34, and opens downside light source 28, so that downside light source 28 is able to upwards shine file on the transparent platform 24 by downside.And sensing veil 36 when not covering upside light source 34 when control circuit 42, control circuit 42 can be opened upside light sources 34, and closes downside light source 28, so that upside light source 34 is able to shine file on the transparent platform 24 downwards by upside.Therefore, when upside light source 34 when crested thing 36 has covered, the document image that image converter 30 is accepted is produced by the light that downside light source 28 irradiation this document back reflections are returned.And when upside light source 34 when crested thing 36 does not cover, downside light source 28 can be closed by Be Controlled circuit 42, and the document image that image converter 30 is accepted then is that the light of crossing by penetrating behind upside light source 34 irradiation this document is produced.
Please refer to another embodiment of scanner 50 of the present invention shown in Fig. 5,6, the difference of this scanner 50 and scanner 20 is the design of its veil 52.This veil 52 comprises; One spool 54 is located at the downside of loam cake 56 and is positioned at a side of upside light source 58; One trip 60 is located at the opposite side of upside light source 58; And an opaque cloth curtain 62, be installed on the spool 54 in rollable mode.Cloth curtain 62 can be pulled out from spool 54, and is fixed in the trip 60, covering upside light source 58, or is wound on the spool 54, so that upside light source 58 is shone the file on the transparent platform 64.Whether scanner 50 also is provided with a sensor 66, is positioned at the next door of trip 60, be used for sensing cloth curtain 62 to be fixed on and to cover upside light source 58 in the trip 60.When scanner 50 sensed the position of cloth curtain 62 via sensor 66, it was identical with scanner 20 to the control mode of upside light source 58, did not therefore repeat them here.
