1254567 九、發明說明： 【發明所屬之技術領域】 本發明係提供一種掃描器，尤指一種可固定欲掃瞄文 件之掃瞄器。 【先前技術】 掃描器是一種非常普遍的電腦周邊產品，它可用來掃描 一實際的平面文件並產生相對應的資料，掃描器也可用來 轉換如相片等之影像或媒體資料，成為可在電腦上實際運 作修改的數位化格式資料。除此之外，它還可以提供某些 附加功能，如掃描器可藉由電話線將影像資料傳真到其他 傳真裝置，或是連接一網路而將影像資料以電子郵件 (e_mail)的格式傳送給其他人，亦或是透過連接一印表機而 達到影印的功能，更可將轉換之數位資料置於網際網路 上，供多人使用。而光學掃描器中的穿透式掃描器 (transmissive scanner )，乃用於掃描透明文件，例如投影 片、幻燈片、底片等。穿透式掃描器係投射一光線穿過待 掃描之透明文件，使得透明文件上的影像能以掃描器轉換 為數位電子形式的資料。 1254567 請參考第1圖與第2圖，第1圖為習知一掃描器10之 示意圖，第2圖為掃描器10掃描透明文件時之侧視示意 圖。掃描器10之主體以一殼體12包覆於外，殼體12上有 一透光平台14用來放置待掃描的文件。主體内包含有一滑 軌16以及一掃描模組18，滑軌16係沿著掃描器10的前 後方向（即箭頭A的方向）固定於殼體12内，而掃描模組 18係以可滑動的方式設置於滑執16上，用來接收由一光 源20發出並穿透一文件22的光線，以產生相對應之感測 訊號。如欲掃描透明之文件22時，必要時可配合一輔助框 24，以挾持文件22。輔助框24上有一開口 26，能讓光線 穿過，輔助框24上的其他部分則是不透光的，輔助框24 之開口 26係對應於文件22的位置。如第2圖所示，如欲 掃描文件22時，便可將文件22放置在開口 26的位置，並 將光源20覆蓋於輔助框24上，讓光源20發出的光線得以 穿過透明的文件22、開口 26及透光平台14，並入射至掃 描模組18中，由掃描模組18將入射的光線轉換為電子形 式的影像資料。 然而，若掃描模組18為一掃描景深淺之接觸式影像感 測器（contact image sensor, CIS)，則在掃描文件22時便需 將文件22緊貼於透光平台14之表面上，以確保文件22之 1254567 掃描品質，而習知掃描器10之輔助框24之設計僅提供將 文件22置放於輔助框24之開口 26内之功能，並未能有效 地將文件22緊貼於透光平台14之表面上；再者，若開口 26之尺寸與文件22之尺寸未能相互配合，則當光源20覆 蓋於輔助框24時，會造成文件22於輔助框24之開口 26 中移位之情況發生，而影響掃描品質。 【發明内容】 本發明係提供一種可固定欲掃瞄文件之掃瞄器，以解決 上述之問題。 本發明之申請專利範圍係揭露一種可固定欲掃瞄文件 之掃瞄器，其包含有一透光平台，用來放置一文件，一光 源，設置於該透光平台之上方，用來發出光線，以及一固 定裝置，設置於該光源上，其包含有一定位機構，包含有 一第一插栓，用來與該文件之第一孔洞相卡合，且該第一 插栓可於該第一插栓與該文件之第一孔洞卡合方向運動， 以及一第一彈性元件，連接於該第一插栓，用來提供一水 平於該第一插栓與該第一孔洞卡合方向之彈力至該第一插 栓，以及一夾緊機構，用來限制該文件於垂直於該第一插 栓與該第一孔洞卡合方向之位移。掃瞄器另包含一掃描模 1254567 組，設置於該透光平台之下方，用來接收由該光源發出並 穿透該文件的光線，並產生對應之感測訊號。 【實施方式】 請參閱第3圖，第3圖為本發明一掃描器30之各元件 的相關位置圖。掃描器30之主體以一殼體32包覆於外， 殼體32上有一透光平台34用來放置待掃描的文件。殼體 _ 32内包含有一滑軌36以及一掃描模組38,滑執36係沿著 掃描器30的前後方向（即箭頭A的方向）固定於殼體32 内，而掃瞄模組38係可為一接觸式影像感測器（contact image sensor，CIS)，且係以可滑動的方式設置於滑軌36 上，用來接收由一自光源40發出並穿透一文件42的光線， 以產生相對應之感測訊號，其中光源40可為一光罩 (transparent media adapter, TMA)，或為一平面光源之光 ^ 板，光源40包含一玻璃43，用來下壓文件42以使文件貼 緊透光平台34 ;而文件42係為一透明之物體，例如底片、 幻燈片、或投影片等。掃描器另包含一固定裝置44，設置 於光源40與透光平台34間，用來固定文件42以使文件 42能緊貼於透光平台34上，藉以增加文件42之掃瞄品質。 請參閱第4圖，第4圖為本發明第一實施例一固定裝 1254567 置44a之不意圖。固定裝置44a包含有一定位機構46，包 含有兩第一支架48a、48b，其上設有兩第一開口 50a、50b。 定位機構46另包含兩第一插栓52a、52b，其中兩第一開 口 50a、50b可分別用來容納兩第一插栓52a、52b，以及兩 第一彈性元件54a、54b，分別連接於兩第一插栓52a、52b 且分別安裝於兩第一支架48a、48b内。固定裝置44a另包 含有一夾緊機構56，包含有兩第二支架58a、58b，其上設 有兩第二開口 60a、60b。夾緊機構56另包含兩第二插栓 62a、62b，其中兩第二開口 60a、60b可分別用來容納兩第 二插栓62a、62b，以及兩第二彈性元件64a、64b，分別連 接於兩第二插栓62a、62b且分別安裝於兩第二支架58a、 58b内。其中兩第一彈性元件54a、54b以及兩第二彈性元 件64a、64b係可為彈簧結構。 由圖中可看出，由於兩第一開口 50a、50b之孔徑與兩 第一插栓52a、52b之外徑相當，故連接於兩第一彈性元件 54a、54b之兩第一插栓52a、52b係恰可穿過兩第一支架 48a、48b之兩第一開口 50a、50b，且僅能做上下之運動（即 箭頭X方向之運動），而兩第一彈性元件54a、54b則係可 提供X方向之彈力至兩第一插栓52a、52b ;此外，由於雨 第二開口 60a、60b之孔徑略大於兩第一開口 50a、50b之 10 1254567 孔徑，且兩第二開口 60a、60b之孔徑略大於兩第二插栓 62a、62b之外徑，故連接於兩第二彈性元件64a、64b之兩 第二插栓62a、62b係可穿過兩第二支架58a、58b之兩第 一開口 60a、60b，且可做上下左右之運動（即箭頭X與γ 方向之運動），而兩第二彈性元件64a、64b則係可提供水 平於X方向與Y方向之彈力至兩第二插栓62a、62b。兩第 一插检52a、52b係由可挽性材質所組成，故可於兩第二開 口 60a、60b中撓曲變形。 請參閱第5圖，第5圖為本發明第一實施例固定装置 44a固定文件42之示意圖。文件42之兩側包含複數個間 隔排列之孔洞。其中兩第一孔洞66a、66b，以及兩第二孔 洞68a、68b，可分別與定位機構46之兩第一插栓52a、52b 及夾緊機構56之兩第二插栓62a、62b相卡合，以固定文 件42於固定裝置44a上。再者於機構設計方面，第一插栓 52a與第二插栓62a之距離可大於文件42之第一孔洞66a 與第二孔洞68a之距離，如此一來若欲將文件42固定於固 定裝置44a時，可先將定位機構46之兩第一插栓52a、52b 與文件42之兩第一孔洞66a、66b相互卡合，而後再將夾 緊機構56之兩第二插栓62a、62b於Y方向撓曲變形以使 兩第二孔洞68a、68b與兩第二插栓62a、62b相互緊密卡 11 1254567 合，並將也就是說此時第二插栓62a、62b於Y方向有約束 文件42位移之作用，而達到夾緊文件42之功效。 請參閱第6圖，第6圖為本發明第一實施例文件42處 於掃描狀態時固定裝置44a固定文件42之示意圖。當文件 42處於掃描狀態時，由於重力之作用使玻璃43壓迫文件 42以使其與透光平台34緊緊相貼，此時固定裝置44a之 兩第一插栓52a、52b以及兩第二插栓62a、62b亦被壓迫 於透光平台34而縮入兩第一支架48a、48b與兩第二支架 58a、58b内，如此一來便可更縮短文件42與掃描模組38 (未顯示於圖中）間之景深，且由於兩第一彈性元件54a、 54b可提供兩第一插栓52a、52b卡合方向（X方向）之彈力， 以及兩第二彈性元件64a、64b可提供兩第二插栓62a、62b 卡合方向（X方向）與垂直於卡合方向（γ方向）之彈力，故 當光源40自透光平台34移除時，由於兩第—插栓52a、 52b以及兩第二插栓62a、62b不再被壓迫於透光平台34， 故可藉由彈力彈出兩第一支架48a、48b與兩第二支架 58a、58b上，而達到固定文件42之功效。 請參閱第7圖，第7圖為本發明第二實施例一固定裝 置44b之示意圖，於本實施例中若與前述實施例具有相同 12 1254567 標號之元件則具有相同結構與功能。固定裝置44b亦包含 有定位機構46，其包含有兩第一支架48a、48b，其上設有 兩第一開口 50a、50b。定位機構46另包含兩第一插栓52a、 52b，其中兩第一開口 50a、50b可分別用來容納兩第一插 栓52a、52b，以及兩第一彈性元件54a、54b，分別連接於 兩第一插检52a、52b且分別安裝於兩第一支架48a、48b 内。與前述實施例相同，兩第一開口 50a、50b之孔徑與兩 第一插栓52a、52b之外徑相當，故連接於兩第一彈性元件 54a、54b之兩第一插栓52a、52b係恰可穿過兩第一支架 48a、48b之兩第一開口 50a、50b，且僅能做上下之運動（即 箭頭X方向之運動），而兩第一彈性元件54a、54b則係可 提供X方向之彈力至兩第一插栓52a、52b。 固定裝置44a另包含有一夾緊機構70，包含有兩第三 支架72a、72b，兩第三插栓74a、74b，以及兩第三彈性元 件76a、76b，分別連接於兩第三插栓74a、74b且分別安裝 於兩第三支架72a、72b内。其中兩第三彈性元件76a、76b 係可為彈簧結構。兩第三插栓74a、74b可做上下左右之運 動（即箭頭X與Y方向之運動），且兩第三彈性元件76a、 76b則係可提供水平於X方向與γ方向之彈力至兩第三插 检 74a、74b。 13 1254567 請參閱第8圖，第8圖為本發明第二實施例固定裝置 44b固定文件42之示意圖。定位機構46之兩第一插栓 52a、52b可與文件42之兩第一孔洞66a、66b相卡合，且 夾緊機構70之兩第三插栓74a、74b可與文件42之兩第三 孔洞78a、78b相卡合，以固定文件42於固定裝置44b上。 如欲將文件42置入固定裝置44b時，可先將定位機構46 之兩第一插栓52a、52b與文件42之兩第一孔洞66a、66b 相互卡合，而後將第三插栓74a、74b卡合於第三孔洞78a、 78b。第三插栓74a、74b可於Y方向上左右彈性移動以與 第三孔洞78a、78b卡合。第三彈性元件76a、76b之彈性 回復力之作用，將使第三插栓74a、74b於Y方向有約束文 件42位移之作用，而達到夾緊文件42之功效。 請參閱第9圖，第9圖為文件42處於掃描狀態時固定 裝置44b固定文件42之示意圖。當文件42處於掃描狀態 時，由於重力之關係，光源40之玻璃43便會壓迫文件42 以使其與透光平台34緊緊相貼，此時固定裝置44b之兩第 一插栓52a、52b以及兩第三插栓74a、74b會被壓迫於透 光平台34 ’兩第一插检52a、52b便會縮入兩第一支架48a、 48b内，至於兩第三插栓74a、74b由於其結構類似懸臂樑 14 1254567 (cantilever)，故此時亦會受到透光平台34壓迫之力量而縮 回第三孔洞78a、78b内，如此一來便可更縮短文件42與 掃描模組38 (未顯示於圖中）間之景深。此外，由於兩第 一彈性元件54a、54b可提供兩第一插栓52a、52b卡合方 向（X方向）之彈力，以及兩第三彈性元件76a、76b可提供 水平與垂直於卡合方向（X方向與γ方向）之彈力，故光源 4〇移走時，由於兩第一插栓52a、52b>以及兩第二插栓62a、 62b不再被壓迫於透光平台34，故可藉由彈簧之回復力彈 出兩第一孔洞66a、66b與兩第三孔洞78a、78b外，而達 到固定文件42之功效。 請參閱第10圖，第10圖為本發明第三實施例_固定 裝置44c之示意圖，於本實施例中若與前述實施例具有相 同標號之元件則具有相同結構與功能。固定裝置44c亦包 含有定位機構46，其包含有兩第一支架48a、48b，其上設 有兩第一開口 50a、50b。定位機構46另包含兩第一插检 52a、52b，其中兩第一開口 50a、50b可分別用來容納兩第 一插栓52a、52b，以及兩第一彈性元件54a、54b，分別連 接於兩第一插栓52a、52b且分別安震於兩第一支架4ga、 48b内。與前述實施例相同，兩第一開口 5〇a、50b之孔;[说 與兩第一插栓52a、52b之外徑相當’故連接於兩第—彈性 15 1254567 元件54a、54b之兩第一插栓52a、52b係恰可穿過兩第一 支架48a、48b之兩第一開口 5〇a、50b，且僅能做卡合方向 之上下運動（即箭頭X方向之運動），而兩第一彈性元件 54a、54b則係可提供X方向之彈力至兩第一插栓52a、52b。 固定裝置44a另包含有一夾緊機構79,包含有兩檔板80a、 80b，用來下壓夾緊文件42(未顯示於圖中），以限制文件 42於X與Y方向之位移。 請參閱第11圖，第11圖為本發明第三實施例固定裝 置44c固定文件42之示意圖。文件42可於穿過兩檔板 80a、80b後’將定位機構46之兩第一插栓52a、52b與文 件42之兩第一孔洞66a、66b相互卡合，之後再下壓兩檔 板80a、80b以使文件42緊貼於玻璃43，而達到夾緊文件 42之功效。 若文件42為諸如單張底片之形式，則可設計一載具承 載該單張底片再使用固定裝置固定之。請參閱第12圖，第 12圖為本發明第四實施例一文件载具82承載文件42之示 意圖。文件載具82包含兩第四插栓84a、84b，用來與文 件42之兩第四孔洞86a、86b卡合以承載文件42。請參閱 第13圖，第13圖為本發明第四實施例固定裝置44c固定 16 1254567 文件42之示意圖。首先可先提起檔板80a，文件42與文

Description of the Invention: [Technical Field] The present invention provides a scanner, and more particularly to a scanner capable of fixing a file to be scanned. [Prior Art] A scanner is a very common computer peripheral product, which can be used to scan an actual flat file and generate corresponding data. The scanner can also be used to convert images or media data such as photos into a computer. The digital format data that was actually modified. In addition, it can provide some additional functions, such as the scanner can fax image data to other fax devices via telephone line, or connect to a network to transmit image data in e-mail format. For others, or by connecting to a printer to achieve photocopying, the converted digital data can be placed on the Internet for use by many people. Transmissive scanners in optical scanners are used to scan transparent documents such as slides, slides, and negatives. A transmissive scanner projects a light through a transparent file to be scanned so that the image on the transparent document can be converted to digital electronic data by the scanner. 1254567 Please refer to FIG. 1 and FIG. 2, FIG. 1 is a schematic view of a conventional scanner 10, and FIG. 2 is a side view showing the scanner 10 scanning a transparent document. The main body of the scanner 10 is covered by a casing 12 having a transparent platform 14 for placing documents to be scanned. The main body includes a slide rail 16 and a scan module 18, and the slide rail 16 is fixed in the housing 12 along the front-rear direction of the scanner 10 (ie, the direction of the arrow A), and the scan module 18 is slidable. The method is disposed on the slider 16 for receiving light emitted by a light source 20 and penetrating a file 22 to generate a corresponding sensing signal. To scan the transparent file 22, an auxiliary frame 24 can be used as necessary to hold the file 22. The auxiliary frame 24 has an opening 26 for allowing light to pass through, and other portions of the auxiliary frame 24 are opaque, and the opening 26 of the auxiliary frame 24 corresponds to the position of the document 22. As shown in FIG. 2, when the document 22 is to be scanned, the document 22 can be placed at the position of the opening 26, and the light source 20 can be covered on the auxiliary frame 24, so that the light emitted by the light source 20 can pass through the transparent file 22 The opening 26 and the transparent platform 14 are incident on the scanning module 18, and the scanning module 18 converts the incident light into image data in electronic form. However, if the scanning module 18 is a contact image sensor (CIS) that scans the shallow depth of field, the document 22 needs to be attached to the surface of the transparent platform 14 when scanning the document 22, The 1254567 scan quality of the document 22 is ensured, and the design of the auxiliary frame 24 of the conventional scanner 10 only provides the function of placing the document 22 in the opening 26 of the auxiliary frame 24, and fails to effectively adhere the document 22 to Further, if the size of the opening 26 does not match the size of the document 22, when the light source 20 covers the auxiliary frame 24, the document 22 is displaced in the opening 26 of the auxiliary frame 24. The situation occurs, which affects the quality of the scan. SUMMARY OF THE INVENTION The present invention provides a scanner that can fix a file to be scanned to solve the above problems. The patent application scope of the present invention discloses a scanner capable of fixing a file to be scanned, comprising a light-transmitting platform for placing a document, and a light source disposed above the light-transmitting platform for emitting light. And a fixing device disposed on the light source, comprising a positioning mechanism, comprising a first plug for engaging with the first hole of the document, and the first plug is applicable to the first plug Moving in a direction of engagement with the first hole of the document, and a first elastic member coupled to the first plug to provide a spring force horizontally to the direction in which the first plug engages the first hole to the a first plug and a clamping mechanism for limiting displacement of the document perpendicular to a direction in which the first plug engages with the first hole. The scanner further includes a scanning module 1254567 disposed under the transparent platform for receiving light emitted by the light source and penetrating the document, and generating a corresponding sensing signal.

The main body of the scanner 30 is covered by a casing 32. The casing 32 has a transparent platform 34 for placing documents to be scanned. The housing _32 includes a slide rail 36 and a scanning module 38. The slide 36 is fixed in the front and rear direction of the scanner 30 (ie, the direction of the arrow A), and the scan module 38 is attached. It can be a contact image sensor (CIS) and is slidably disposed on the slide rail 36 for receiving light emitted from the light source 40 and penetrating a file 42 to A corresponding sensing signal is generated, wherein the light source 40 can be a transparent media adapter (TMA) or a light source of a planar light source, and the light source 40 includes a glass 43 for pressing the file 42 to make the file The light-transmissive platform 34 is attached to the substrate 44; and the document 42 is a transparent object such as a film, a slide, or a slide. The scanner further includes a fixture 44 disposed between the light source 40 and the light transmissive platform 34 for securing the document 42 to enable the document 42 to adhere to the light transmissive platform 34, thereby increasing the scanning quality of the document 42. Please refer to FIG. 4, which is a schematic view of a first embodiment of the present invention in which a fixed device 1254567 is disposed 44a. The fixture 44a includes a positioning mechanism 46 that includes two first brackets 48a, 48b on which are disposed two first openings 50a, 50b.
