Description
The utility model relates to a kind of scanister, especially relates to a kind of reflection and penetration type scanner.
Known reflective optic device of image scanning on the market now, majority is the purpose that reaches scanning transmission original text (for example lantern slide, transparency or egative film etc.) by the mode that lamp source module on (for example going up fluorescent tube, light list or backlight pulling) is set in the loam cake increase.Yet; since this kind transmission original text scan mode its go up light that lamp source module sent need be subjected to layer glass at least (one be positioned at lamp source module in order to protect fluorescent tube, another is positioned at the scanister body to bear this transmission original text) obstruct; so its not only be vulnerable to cleaning glass degree, flatness, and the influence of penetrability etc. make not optimum serious multiplication; and also will cause the reduction of scan-image quality, and can't further promote the image definition and the quality of high unit price or high-res scanister because of the effect of Newton ring.
Afterwards, there were some technology to be solved foregoing problems by exposure.For example, No. 87206369 case of TaiWan, China number of patent application, disclose the two platform scanner devices of a kind of reflection and transmission, its in order to lamp source that transmission original text scanning is provided at most an alternating floor glass just the lamp source can be projected on the transmission original text to be scanned, can obtain the scanning effect of relative better quality thus, yet the embodiment of disclosed multinomial located by prior art in No. 87206369 cases all has following common shortcoming:
(1) need a rotatable eyeglass to carry out the switching of light path at least.In case be used for the element that the eyeglass of reflection source is designed to a rotatable or motion, being positioned at of its rotation is bound to take place deviation to a certain degree under the long-time use, will therefore cause the reduction of scanning quality and is not suitable for senior machine.
(2) some embodiment must use light splitting piece, because light splitting piece the time can cover (reflection or scattering) and fall many light carrying out the scanning of transmission original text, and also is restricted in the quality of carrying out reflex time, so scanning quality is lower and be not suitable for senior machine.
(3) some embodiment must use changeable mobile anti-dazzling screen so that switch shading when different scanning pattern (for example reflective or transmission-type), so must many drivings be set additionally and actuated element removes to drive this anti-dazzling screen, not only cost height but also failure rate improve.
Again, located by prior art is as the device of image scanning of No. 84204336 novel patent application case exposure, it also can do reflection and the two-in-one scanning of penetration respectively according to user's selection, it disposes with traditional chassis (Chassis), reflection is configured to cooperate different paths light path with the required eyeglass of penetration need rotational angle or different angles on the mobile platform, and light source also must rotational angle cooperates the light path in different paths.More and the complex structure of its required element is with a motor eyeglass to be rotated an angle when reflecting and penetrate the scan pattern switching, and eyeglass is a dynamic element.Because its eyeglass is bound to take place to a certain degree deviation in being positioned at of rotation under the long-time use, therefore causes the reduction of scanning quality and be not suitable for senior machine.
For another example, No. 88204377 disclosed multi-functional image capture unit of novel patent application case, it also is to use the spectroscope of an optional gyration to carry out the switching of light path to reach the purpose of reflection and transmission scan, so it also has No. 87206369 identical shortcoming of case as described above.In addition, also because No. 88204377 case is only applicable to the scanning work of small-sized object (for example major part according to or egative film etc.), it is lower but also be not suitable for the scanning work of large-sized object that it not only scans resolution.
In fact, general scanister fabricator all knows, for the scanning work that generally will carry out large-size object (for example B3 size), and need senior high unit price scanister with high scanning quality (for example more than the 1200dpi Optical Resolution), except need adopt more the charge coupled cell of high-res (CCD), also owing to the required light path path of its blur-free imaging is longer, so be to adopt bireflection eyeglass module it carries out relative motion with two-to-one velocity ratio between the two mostly, the total optical path length (Total Track) that can significantly prolong imaging reaches the purpose of blur-free imaging.Because, about how carrying out the gear train of bireflection eyeglass module with two-to-one speed relative motion, for located by prior art and be not the main demand feature of this case, so following content will repeat no more, specifically can be with reference to TaiWan, China patent application case number No. 84213459 case and No. 85200915 case contents.
Yet, as previously mentioned, no matter be No. 87206369 case of TaiWan, China number of patent application, No. 84204336 case, No. 88204377 case or now in visible any can not using light shield, going up lamp source or backlight and just reflect scanister with the double mode scanning of transmission of commonly using on the market, all can't cooperate aforesaid bireflection eyeglass module to use with two-to-one speed relative motion, so all can't when carrying out the scanning of large scale object, provide a stable and high-quality transmission-type scanning image, therefore need further improvement.
The purpose of this utility model is to provide a kind of reflection and penetration type scanner, its not only device have with what two-to-one speed moved and two move the reflection module, scanning work applicable to large scale contribution and high scanning quality, and the emission eyeglass is to be fixed in to move on the reflection module, and the location is accurate and can obtain preferable and more stable quality of scanning.
