Description
Technical field:
The variable reflection/transmission one of single light source film direct exposure scanner belongs to sensitization scanner technical field.Be particularly related to a kind of unique light source that utilizes, You Zhineng does the scanning of reflective medium image and penetration medium image respectively according to user's selection.
Background technology:
The scan mode of device of image scanning (as scanner) can be categorized as reflective medium image and penetration medium image dual mode scanning document usually.
The reflective scanning mode mode is applicable to opaque file, and as paper or photograph etc., wherein, the scanning light source of reflective scanning mode is positioned at the below of file to be scanned, utilizes the reflected light signal of light supply apparatus shot file and finishes scanning;
The penetration scan mode is applicable to transparent or semitransparent file, and as egative film or transparency etc., wherein, the scanning light source of penetration scanning is positioned at the top of file to be scanned, and the light signal that penetrates that utilizes the light of light supply apparatus to pass file is finished scanning;
At the different images medium, its exclusive device of image scanning is arranged all generally.That is reflective medium device of image scanning can not scan penetration medium image.Vice versa.
The applying date be on October 15th, 1997, open day are that April 14, application number in 1999 are 97120079.3, Chinese invention patent that name is called " scanner " proposed a kind of alternative that is used for and has been installed in scanning light source light shield on the scanning gantry, though it has only used a light source, but strengthened the volume of scanner, increase cost, carried inconvenience.The applying date be April 14 nineteen ninety-five, open day are that April 9, application number in 1997 are 95103826.5, Chinese invention patent that name is called " device of image scanning " proposed upper and lower two light sources of a kind of use, change two light source sensitization scanners of the reflection/transmission one of reflection/transmission mode by the position that changes catoptron with a mode selecting arrangement, its shortcoming is to use the device complexity of upper and lower two light sources and control mode, bulky, need two groups of scanning light source assemblies, the production cost height.
The utility model discloses a kind of dual-purpose platform image scanister, and this device can carry out the image scan of penetration medium or reflective medium respectively according to user's selection.
Summary of the invention:
The purpose of this utility model is to provide a kind of to use a light source and the variable reflection/transmission one of single light source film direct exposure scanner simple in structure, that cost is lower, easy to use.It will carry out the device of image scanning of penetration medium and reflective medium, all place the inner space of lower casing, the volume of dual-purpose type device of image scanning is greatly reduced, and unique light source can direct exposure when scanning penetration medium to the film information face, and utilize unique light source and unique actuated element, its frame and light source can same moved further, reduce manufacturing cost simultaneously improving the scanning effect.
Of the present utility model being characterised in that: it contains: shell at the upper and lower socket that respectively has a film support and scanning mode switch boards of its Width one side, has the printing opacity mouth at the top; The upper and lower guide rail that runs through shell along its length; The mirror group, contain: there is the printing opacity mouth at the top and has the mirror shell that can switch the breach that the medial surface about upper and lower two positions of mirror group can make self upper and lower again slides on upper rail in the broad ways both sides, be installed in mirror shell inwall both sides along its length and be positioned at the swing type crank arm mechanism of upper rail superjacent air space, be contained on the crank arm driven end and the fluorescent tube in the printing opacity mouth of shell top of extending, the receiving light path that is contained in the mirror shell and constitutes by catoptron, condenser lens, CCD optoelectronic sensor.When reflective sensitization scanned, film supported and the scanning mode switch boards, should be inserted under the power wheel of mirror group bottom; When transmission-type sensitization scanned, film supported and the scanning mode switch boards, between fluorescent tube and mirror group top printing opacity mouth; The described swing type crank arm mechanism that is positioned at the upper rail superjacent air space is the spring drive-type.
Experimental results show that: it simple in structure, easy to use, cost is lower, has reached intended purposes.
Description of drawings:
Fig. 1: the horizontal partial sectional view of the variable reflection/transmission one of the single light source during reflective scanning mode film direct exposure scanner;
Fig. 2: the horizontal partial sectional view of the variable reflection/transmission one of the single light source during transmission-type scanning film direct exposure scanner;
Embodiment:
See Fig. 1.Among the figure: scanner shell 1, transmissive mirror 2, photo 3, mirror group 4 also can be placed directly in photo 3 on the printing opacity mouth without transmissive mirror 2, and is not shown among Fig. 1.Fixing pin 5 is fixing pins of fixing spring 6 usefulness, and movable pin 7 connects spring 6 and crank arm 9, and stationary shaft 8 is slidingly connected with crank arm 9, crank arm 9 connects fluorescent tube 10, mirror group 4 has two along scanner shell 1 Width, on same surface level through upper rail 11; The 12nd, the catoptron on the receiving light path, have three, the 13rd, be bonded on the mirror group 4 broad ways inwalls, be used for connecting the link of catoptron 12, also there are three, the 14th, be screwed the condenser lens on mirror group 4 inner bottom surfaces, the 15th, the CCD photoelectric coupled device, it is the imaging sensor, the 16th, be contained in four rotor wheels of mirror group 4 bottoms, by motor-driven, not shown in the figures, film 17, it can also can be contained in following transmissive mirror 2 separately in film support and the scanning mode switch boards 19 together, and the 18th, the fixing nut, mirror group lower guideway 20 used, also there are two along shell 1 Width, on same surface level.
See Fig. 2, different with Fig. 1 is, when doing transmission-type sensitization scanning, to extract film support and scanning mode switch boards 19 out from the following socket 23 of shell 1 broad ways, at this moment, mirror group 4 descends naturally, the upper inner face of the breach of mirror group 4 broad ways just contacts with upper rail 11, crank arm 9 clockwise direction under 6 effects of crank support spring is rotated, withstand on the bottom surface of the transmissive mirror 2 at shell 1 top once more, at this moment, on transmissive mirror 2, add plane mirror 12, film is supported and scanning mode switch boards 19 is inserted between fluorescent tubes 10 and the mirror group 4 from the last socket 22 of shell 1 broad ways, just can make transmission-type sensitization scanning usefulness.Film 17, it can be contained in film support and the scanning mode switch boards 19, and by plateholder 21 clampings, at this moment, the rotor wheel 16 of mirror shell 4 bottoms just frame under motor-driven, just can drive the mirror group along laterally sensitization scanning on lower guideway 20.
This shows that this scanner has simple in structure; Easy to use, only just can realize reflection, transmission scan with a light source, one group of transmission.
