【發明所屬之技術領域】 α。本案係指一種具有多焦距及多解析度之接觸式影像掃蹈器’尤指一種可應用於具有不同掃瞄影像焦矩之待掃猫物件的接觸式影像掃瞄器。【先前技術】接觸式影像感測器（contact image sensor，CIS)模組的工作原理是將光源所產生的光線照射到待掃晦的稿件上，經過鏡片組的反射，再聚集於電荷耦合元件 (charge-coupled device，CCD)或是互補式金屬氧化物半導體(complementary metal oxide semiconductor， CMOS)之上由其接收後，利用這類型的感光元件將光的訊號轉變為電的訊號，進而產生出類比或數位畫素（pixel) 資料。在掃瞄的過程中，由於CCD可以檢測影像上不同區域反射回來不同強度的光，因此利用紙張上較暗的區域反射較少的光、較亮的區域反射較多的光的原理，可以將 CCD所反射的光波轉換為類比或數位資料，此電訊訊號會與光的強度成正比，最後，再使用與CIS相容的文字或影像掃瞄軟體讀入這些數據，並將其重組為電腦影像檔。由於優異的C I S取像表現仰賴成熟的光控制技術，因此由光學模組所獲取的影像品質不但重要，更是影響CIS運作表現的主要成因之一。[Technical field to which the invention belongs] α. This case refers to a contact image scanner with multiple focal lengths and multiple resolutions, and more particularly a contact image scanner that can be applied to cat objects to be scanned with different focal moments of the scanned image. [Prior technology] The working principle of the contact image sensor (CIS) module is to irradiate the light generated by the light source onto the manuscript to be scanned, reflected by the lens group, and then concentrated on the charge-coupled element. (charge-coupled device, CCD) or complementary metal oxide semiconductor (CMOS) after receiving it, using this type of photosensitive element to convert the light signal into an electrical signal, and then generate Analog or digital pixel data. During the scanning process, since the CCD can detect light with different intensity reflected from different areas on the image, the principle that less light is reflected on the darker areas of the paper and more light is reflected on the lighter areas can be used. The light waves reflected by the CCD are converted into analog or digital data. This signal is proportional to the intensity of the light. Finally, the data is read using CIS-compatible text or image scanning software and recombined into computer images. files. Since excellent C I S imaging performance relies on mature light control technology, the image quality obtained by the optical module is not only important, but also one of the main reasons affecting the performance of CIS.

1240556 五、發明說明（2) &目岫主流的光學影像之取像方法即為前述被稱為接觸式景>像感測器（contact image sensor ’CIS)的技術，其是以模組化的型態，將光源、柱狀透鏡、感測基板及外殼等組合在一起。明參考第一圖（a)，其為習知技術中應用接觸式影像感測器技術之掃瞄模組的結構圖。其中，掃瞄模組丨〇係由光源11、柱狀透鏡（Rod lens)12、間距元件（spacer)13、玻璃（cover glass)14以及電路板15所共同結合而成；而1240556 V. Description of the invention (2) & The mainstream optical image acquisition method is the aforementioned technology called contact image sensor 'CIS', which is a module The light-emitting type combines a light source, a lenticular lens, a sensing substrate, and a housing. Reference is made to the first figure (a), which is a structural diagram of a scanning module using a contact image sensor technology in the conventional technology. Among them, the scanning module 丨〇 is a combination of a light source 11, a rod lens 12, a spacer 13, a cover glass 14, and a circuit board 15; and

電路板1 5上更具有由CCD或是CM0S所構成的一感光元件 1 6 〇在利用掃瞄模組1 〇進行掃瞄物件的過程中，係以玻璃 14為基準面，藉由間距元件13來保持柱狀透鏡12至掃描物件的焦距為一固定距離，再藉由柱狀透鏡12將光源u發出的光$物件反射之後所產生的物像聚焦至感光元件16上，以獲得影像之訊號。由於一般的待掃描物件丨7通常係與玻璃1 4平貼’因此非常容易保持固定的焦距，使得掃描品質良好，如第一圖（b)所示。、一惟當待掃描物件為幻燈片、底片等時，如第一圖（c)The circuit board 15 further has a light-sensitive element 16 composed of a CCD or a CM0S. During the process of scanning an object by using the scanning module 10, the glass 14 is used as a reference plane, and the distance element 13 is used. To keep the focal length of the lenticular lens 12 to the scanned object at a fixed distance, and then focus the object image generated by the lenticular lens 12 to reflect the light from the object u to the photosensitive element 16 to obtain the image signal . Since the general object to be scanned 7 is usually attached flat to the glass 14 ', it is very easy to maintain a fixed focal length and make the scanning quality good, as shown in the first figure (b). 1. When the object to be scanned is a slide, a negative, etc., such as the first picture (c)

所不’因為待掃描物件1 8所具有的外框造成被掃描面並非平貼在玻璃14上，而是與玻璃14之間具有一段距離時，此 ¥傳統的掃描設備並無法同時適用兩種不同位置的被掃描物件（平貼破璃14及位於玻璃14的上方），而容易造成影像擁取口口貝之調變轉換函數（MTF，Modulation Transfer Function)不良，因此其掃描品質始終為人所詬病。What's wrong? When the scanned surface is not flat on the glass 14 because of the outer frame of the object to be scanned 18, this traditional scanning equipment cannot be used for both types at the same time. Scanned objects at different positions (flatly attached to the broken glass 14 and located above the glass 14), which will easily cause the modulation transfer function (MTF, Modulation Transfer Function) of the image capture mouth and mouth, so its scanning quality is always human So criticized.

第6頁 1240556 >、發明說明（3) 要解決上述因具有不同掃瞄影像焦距之待掃瞄物件所造成的問題，目前較為普遍的技術係使用可變化高度的間距元件13，也就是說，藉由升降技術來改變間距元件13的位置，進而調整第一圖（b)及第一圖（c)中所需之不同的相對焦距，使得柱狀透鏡1 2的表面到不同的被掃描物件j 7 (平貼玻璃）或18(在玻璃上方）的距離皆能相同。然而，因為間距元件1 3 —般係以塑膠滾珠、鋼珠、滑軌等組合而成，其所具有公差、變形、磨損等因素很容易在使用的過程中使得升降的高度在精確度的控制上變得困難；另外，右疋須使用小尺寸的待掃描物件，例如：幻燈片、底片等’而須要較南解析度的掃描時，亦無法使用一般的掃描器，而須更換成具有更高解析度的接觸式影像掃瞄器，這不但相當不方便、亦不符合經濟原則。為了消除這種問題，日本專利特開2004 — 〗26284號公報提出了一種具有雙焦距及雙解析度之接觸式影像掃瞄器，如第二圖（a)及（b)所示。與前述之諸多技術不同的是，其係利用兩排平行排列於電路板25上的感光元件陣列（3^”）26及27，分別對應具不同焦距的柱狀透鏡2 2及23，來適應具有不同掃瞄影像焦距之待掃猫物件28及29，以消除其所造成成像不良的問題，請參閱第二圖（a)及（b)之示意圖。攸表面上來看，日本專利特開2〇〇4—1 26284號公報似乎已經解決了先前技術所面臨的所有問題，實則不然，對於熟驾接觸式影像掃瞒器之成像原理&製作技術的技術者Page 6 1240556 > Description of the invention (3) To solve the above-mentioned problems caused by objects to be scanned with different focal lengths of the scanned image, the currently more common technology is to use a variable height pitch element 13, that is, By changing the position of the pitch element 13 through the lifting technology, and then adjusting the different relative focal lengths required in the first image (b) and the first image (c), the surface of the lenticular lens 12 is scanned differently. The distance between object j 7 (flat glass) or 18 (above the glass) can be the same. However, because the pitch element 1 3 is generally made of a combination of plastic balls, steel balls, slide rails, etc., its tolerances, deformation, wear and other factors can easily make the height of the lift in the accuracy control in the process of use It becomes difficult; in addition, the right side must use a small size of the object to be scanned, such as slides, negatives, etc., and when scanning at a lower resolution than a normal resolution, a general scanner cannot be used, and it must be replaced with a higher The resolution of a contact image scanner is not only inconvenient, but also not in line with economic principles. In order to eliminate such a problem, Japanese Patent Laid-Open No. 2004-26726 proposes a contact image scanner with dual focal lengths and dual resolutions, as shown in the second figures (a) and (b). Unlike many of the aforementioned technologies, it uses two rows of photosensitive element arrays (3 ^ ”) 26 and 27 arranged in parallel on the circuit board 25, corresponding to the lenticular lenses 2 2 and 23 with different focal lengths, respectively. Cat objects to be scanned 28 and 29 with different focal lengths of the scanning image to eliminate the problem of poor imaging caused by them, please refer to the schematic diagrams in (a) and (b) of the second figure. On the surface, Japanese Patent Laid-Open No. 2 〇〇4-1—26284 seems to have solved all the problems faced by the previous technology, but it is not true. For those who are familiar with the imaging principle of the contact image concealer & the production technology

1240556 五、發明說明（4) 來說’該日本專利之技術不但適用範圍狹小，且製造了更多使用上的問題。首先，固定以平行方式排列的感光元件陣列26及27，限制了與其對應之柱狀透鏡2 2及2 3的相對位置及排列方式’連鎖性地使得該接觸式影像掃瞄器的體積受到限制，為了滿足裝置微型化的趨勢，勢必要對所使用之柱狀透鏡的數目作限制，這也是該專利僅適用於兩組柱狀透鏡的原因。其-人，由於只有兩組柱狀透鏡和感光元件陣列，因此該專利在待掃瞄物件之可應用的範圍上便受到相當的侷限，亦即，可以應用之待掃瞄物件28及29的不焦距範圍不夠廣泛。〜体再者，感光元件陣列26及27、柱狀透鏡22及23 '以及電路板25之相對位置皆為固定，與先前技術比較起來雖然增加了一個不同的掃瞄焦距及解析度，實際上其掃瞄隹距度仍然不具有可調變性，{故，仍然只：能治本。職是之故，申請人鑑於習知技術之缺失，采、驗與研究，並一本鍥而不捨之精神，終構思出本案=且有多焦距及多解析度之接觸式影像掃瞄器」。 ^ ς 簡要說明。卜马本案之發明内容第8頁 1240556 五、發明說明（5) 本案之主要構想為提出一種具有多焦距及多解析产之接觸式影像掃瞄器，其可應用於具有不同掃瞄影像隹距之待掃瞄物件。 …、本案是將不同特性之兩組或多組柱狀透鏡、兩組或多組感光70件、以及一只或兩只以上的電路板組合於一接觸 ί Ϊ Ϊ内：成為一組光學元件，能適用於雙或多功能存=象知描，以滿足不同解析度之物件掃描或其他不同高度特性的被掃描物件來使用。組感ί =將或多組柱狀透鏡、兩組或多式影像模組内，成為：：組光學^的= = -接觸 ^ ^ ^ 兀*子1千亚搭配系統端的問距 $ ρ璃’以掃描具有不同掃瞒影像焦距之待掃瞒物 :機影像掃瞒器能具有多焦距及多解析度之機雙用或多用的功能。〜又< 之柱ΐ被ί描面位置不同時需選擇或調整不同來付合不同高度之掃描面的需求。辱又玻璃厚度等本案在電路板的設計上可同片（二片或多片）的電路板上放在-片或放不能力，而當感光元件被放置於 ^成又或多功能之掃描整電路板相對於不同高度之立同片之電路板上時，可調求。 ’以達到所需之光學需本案針對每一特定之需求（如得知骑物件之高度或解 1240556 五、發明說明（6) 析度不同），會有適合之感光元件與柱狀透鏡相配合之固定結構，並可依使用的需求作切換，因此每一特定之被掃描面與焦距位置會是相當準確，所得之掃描品質亦能得到良好的品質。本案得藉由下列圖式及詳細說明，俾得更深入之了解：【實施方式】1240556 V. Description of the invention (4) As far as the technology of this Japanese patent is concerned, it not only has a narrow scope of application, but also creates more problems in use. First, the parallel array of photosensitive element arrays 26 and 27 is fixed, limiting the relative position and arrangement of the corresponding lenticular lenses 2 2 and 23, so that the volume of the contact image scanner is limited. In order to meet the trend of device miniaturization, it is necessary to limit the number of lenticular lenses used, which is why the patent is only applicable to two sets of lenticular lenses. Its-man, since there are only two sets of lenticular lenses and photosensitive element arrays, the patent is quite limited in the applicable scope of the objects to be scanned, that is, the objects to be scanned 28 and 29 that can be applied The out-of-focus range is not wide enough. In addition, the relative positions of the photosensitive element arrays 26 and 27, the lenticular lenses 22 and 23 ', and the circuit board 25 are fixed. Compared with the prior art, although a different scanning focal length and resolution are added, in fact, Its scanning distance still has no tunability, {so, still only: can cure the root cause. For this reason, the applicant, in view of the lack of known technology, has adopted research, experimentation, and research, and has a spirit of perseverance, and finally conceived this case = a contact image scanner with multiple focal lengths and multiple resolutions. " ^ ς Brief description. The content of the invention of Bu Ma's case on page 8 1240556 V. Description of the invention (5) The main idea of this case is to propose a contact image scanner with multiple focal lengths and multiple resolutions, which can be applied to different scanning image pitches. Objects to be scanned. …. This case combines two or more sets of lenticular lenses with different characteristics, two or more sets of 70 photosensitive elements, and one or more circuit boards in one contact. Ϊ Ϊ: Become a set of optical elements It can be applied to dual or multi-functional storage = Xiangzhi tracing to meet the scanning of objects with different resolutions or other scanned objects with different height characteristics. Sense of grouping = put a plurality of groups of lenticular lenses, two or more types of image modules into :: group optics ^ = =-contact ^ ^ 兀 * 1 thousand Asian pairs with the system distance $ ρ 璃'To scan objects to be concealed with different focal lengths of the concealed image: the machine image concealer can have multi-focus and multi-resolution functions of dual or multiple functions of the machine. When the position of the painted surface is different, you need to select or adjust it to meet the needs of scanning surfaces of different heights. In this case, the thickness of the glass can be placed on the same (two or more) circuit boards in the design of the circuit board, or it cannot be placed, and when the photosensitive element is placed in a multi-functional or multi-functional scanning The whole circuit board can be adjusted when it is relative to the same circuit boards of different heights. 'In order to achieve the required optical requirements, this case is for each specific requirement (such as knowing the height of the riding object or solution 1240556 V. Description of the invention (6) Different resolution), there will be suitable photosensitive elements to cooperate with the lenticular lens The fixed structure can be switched according to the requirements of use, so each specific scanned surface and focal position will be quite accurate, and the obtained scanning quality can also get good quality. This case can be understood in more depth through the following drawings and detailed description: [Embodiment]
