組中的反射稿光源，將光線投射於被讀取稿件的表面，使 得光線從被謓取稿件的表面反射，然後再經由反射鏡Η組 與鏡頭組的傳遞，而使得被讀取稿件的影像聚焦於感測元 件上，以產生該影像的電子訊號。而當該掃描器要謓取穿 透稿時，則需搭配一個穿透稿光源装置，該穿透稿光源裝 置係設置在被謓取稿件的上方，且該穿透稿光源裝置所發 出的光線必須先穿透過被讀取稿件之後*再經由反射鏡片 組與鏡頭組的傅遞，而使得被謓取稿件的影像聚焦於感測 元件上，Μ產生該影像的電子訊號。 習用的掃描器所使用的穿透稿光源裝置可分為二種， 一種是光板的塑式，其係提供一個平面的光源*而旦位置 是固定的；而另外一種則是使用長條形燈管型式的光源， 且該光源會隨著掃描模組的移動，而做同步的移動。而穿 透稿一般可分為正片及負片，由於正片的透明度較高，因 此穿透稿光源裝置所發出的光線可穿透過正片的數量較多 ;而因負片的透明度較低，因此該穿透稿光源裝置所發出 的光線可穿透過負片的光線數量較少，約只有正片的三分 — 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐） ------------- — I -III--— I « — — — — —— I— (請先閱讀背面之注意事項再填寫本頁) 五 經濟部智慧財產局員Η消費合作杜印製 A7 B7 發明說明（） 之一左右。

型式的穿透稿光源裝置來謓取穿透稿’都會因該穿透稿光 源裝置的亮度只有一種，而使得該掃描器在謓取負片時， 其所需要的讚取時間約為讀取正片時所需要的時間的三倍 ，才能得到與正片相同的電子訊號強度。 為解決上述問題*習用的掃描器使用前述穿透稿光源 裝置謓取負Η時，係採用將謓取負片時的掃描模組移動速 度減低到為謓取正片時的掃描模組移動速度的三分之一， Μ延長該掃描橫組謫取負片的時間，而使得進入感測元件 的光線數量增加三倍*以得到相同的電子訊號強度。然而 採用該種方法卻會使得掃描模組的謓取速度減慢，而使得 掃描器謓取負片時的操作時間加長。 本發明人有鑒於此，乃苦思細索，積極研究，加以多 年從事相關產品研發之經驗，終於發展出本發明。 發明概述： 本發明之目的，係在於提供至少兩個光源輸出，其具 有不同的亮度，分別供掃描器於謓取正片及負Μ時使用， Μ得到相近的電子訊號強度的掃描器穿透稿光源装置。 —3

Description of the invention () Background of the invention: The present invention is a scanner penetrating light source device * especially refers to a scanner to provide positive film Scanner with negative penetrating manuscript penetrating manuscript light source device. Press, the conventional scanner is mainly used to get the reflection draft. If you want to get through the transmission draft *, you need to use a penetrating light source device to capture the transmission draft. When the scanner wants to fetch the reflection manuscript, it uses the reflection manuscript light source in the scanner's scanning module to project light onto the surface of the manuscript being read, so that the light is reflected from the surface of the manuscript being picked up, and then Through the transmission of the mirror group and the lens group, the image of the read manuscript is focused on the sensing element to generate an electronic signal of the image. When the scanner is to capture the penetrating manuscript, it needs to be equipped with a penetrating manuscript light source device. The penetrating manuscript light source device is arranged above the manuscript being picked up, and the light emitted by the penetrating manuscript light source device is provided. The manuscript must be transmitted through the read manuscript first * and then transmitted through the reflection lens group and the lens group, so that the captured manuscript image is focused on the sensing element, and the electronic signal of the image is generated. The penetrating light source device used by conventional scanners can be divided into two types. One is the plastic type of the light plate, which provides a flat light source *, and the position is fixed; the other is a strip light. A tube-type light source, and the light source moves synchronously with the movement of the scanning module. Transparency can generally be divided into positive and negative. Because the transparency of the positive is higher, the light emitted by the light source device of the penetration can pass through the positive; moreover, because the transparency of the negative is low, the penetration The light emitted by the light source device can pass through the negative film. The amount of light is relatively small, only about three-thirds of the positive film. — This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) ------- ------ — I -III --— I «— — — — — — I— (Please read the precautions on the back before filling out this page) Five members of the Intellectual Property Bureau of the Ministry of Economic Affairs and Consumer Cooperation Du printed A7 B7 Invention description () around one. The sensor elements used in conventional scanners are mainly KCCD (Charse Coupled Device) or CIS (Contact Image Sensor ·). Regardless of the CCD or CIS sensor element, the strength of the electronic signal generated by the sensor is similar to that of the sensor. The amount of light of the sensing element is directly proportional, that is, the more the number of rays of light entering the sensing element, the stronger the intensity of the electronic signal generated by the sensing element. Therefore, no matter which type of penetrating manuscript light source device is used by the aforementioned scanner to capture penetrating manuscripts, because the penetrating manuscript light source device has only one type of brightness, the scanner will not The required praise time is about three times the time required to read the positive film, so as to obtain the same electronic signal strength as the positive film. In order to solve the above problem, when a conventional scanner uses the aforementioned penetrating light source device to take a negative film, the scanning module is used to reduce the moving speed of the scanning module when taking a negative film to three times the moving speed of the scanning module when taking a positive film. For one-half, M prolongs the scanning time of the negative scanning group to increase the amount of light entering the sensing element by three times * to obtain the same electronic signal intensity. However, adopting this method will slow down the scanning speed of the scanning module, and make the operation time of scanning the negative film longer. In view of this, the present inventor has been thinking hard, actively researching, and having years of experience in research and development of related products, and finally developed the present invention. Summary of the invention: The purpose of the present invention is to provide at least two light source outputs with different brightnesses, which are used by the scanner when capturing positive and negative M, respectively. Μ obtains a scanner penetrating draft with similar electronic signal strength.

Description of the invention () Another object of the present invention is to provide at least Two light source outputs with different brightness, which are used by the scanner when taking the positive and negative, respectively, so that the scanner penetrates the light source device when the scanner does not need to reduce the speed of the scanner when taking the negative . The special feature of the scanner penetrating light source device is that the scanner penetrating light source device can generate at least two light source outputs with different brightness. When the positive film is taken, the light source output with lower brightness is used to provide light; When the negative is captured, the light source output with higher brightness is used to provide light. Therefore, when the scanner uses the scanner of the present invention to penetrate the manuscript light source device to capture the negative, there is no need to reduce its scanning due to insufficient brightness of the light source. The module's moving speed * can effectively increase the scanning speed when the scanner is capturing negatives and increase the strength of the electronic signal.

The scanning module 30 includes: a reflective light source 31 for providing light required for reading reflection; and at least one lens group 50, a reflective lens group 40, and at least one sensing element 60. The light passing through the manuscript light source 70 passes through the manuscript 20 to be read, passes through the reflection lens group 40 and the lens group 50, and finally focuses on the sensing element 60, so that the manuscript 20 is allowed to be fetched.

Description of the invention () The first light source with a low degree of output 70A provides the light required to capture the manuscript 20; and when the scan module When taking a negative film at 30 謓, a second light source with a higher brightness can be used to output 70B * M to provide more light, so that the scanner of the present invention does not need to reduce the speed of the scanning horizontal group 30 when reading the negative film. Therefore, it does not affect the operation time of the scanner to read negatives. The penetrating light source 70 of the first cell example has: a body 71, which is installed inside the cover plate 12, and a guide device 72, which is used to erect the body 71 and to guide the body 71 along The indexing device 72 is moved; and a light-emitting element 73 is used to generate the light required to capture the captured manuscript 20. The light generated by the light-emitting element 73 can be radiated vertically downward to form a second light source output 70B; and a reflective sheet 74 is disposed in front of the light-emitting element 73, so that the light generated by the light-emitting element 73 can be first After the horizontal movement, it is refractioned by the reflection sheet 74 to change the direction and illuminate downward; and a light shielding sheet 75 is disposed below the reflection sheet 71, and M allows the light generated by the light emitting element 73 to pass through the The light-shielding sheet 75 * forms a first light source output 70A. The first embodiment of the present invention uses a single light-emitting element 73, and is combined with a reflective sheet 74 and a light-shielding sheet 75, so that the light generated by the light-emitting element 73 can be output from different positions, and a first light source output 70A and a second light source are generated. Output 70B. Since the light-shielding sheet 75 can reduce the brightness of the light generated by the light-emitting element 73, the brightness of the first light source output 70A is smaller than the brightness of the second light source output 70B. Therefore, the scanning module 30 obtains a negative value and a negative value. For positive films, the same picking speed can be used, so it can effectively save the operation time of the scanner when reading negative films. -7- This paper size applies to Chinese national standard (CNS > A4 specification (210 X 297 mm) -----— — — — — 111 --- II 1 丨 —Order ------- (Please Read the notes on the back before filling this page) Member of the Intellectual Property Bureau of the Ministry of Economic Affairs II Consumption printed by Akasaku A7 _____B7_ V. Description of the invention () As shown in Figure 1 and Figure 2, the light source is a penetrating manuscript 7〇 Scanning module 30 works in positive and negative modes. As shown in Figure 1, 'when scanning horizontal group 30 to take positives', the first light source output 70A is used to provide access to the captured manuscript 20 Therefore, the penetrating light source 70 must be moved to a first position 76A where the first light source output 70A and the light entering position 41 of the scanning module 30 are aligned with each other; and as shown in FIG. 2, when the scanning module 30 When switching to scan mode for capturing negatives, the data is captured using the second light source output 70B with higher brightness *.

The fourth embodiment of the invention is different from the first example in that the penetrating light source 70 is directly fixed on the scanning unit 30 . When the scanning wedge group 30 moves, the penetrating light source 70 moves along with the scanning module 30. As shown in FIG. 6, the fixed position of the penetrating light source 70 is the first position 76A where the first light source output 70A with lower brightness and the light entering position 41 of the scanning module 30 are aligned with each other. As shown in FIG. 7 *, the fixed position of the penetrating light source 70 is a second position 76B where the second light source output 70B with higher brightness and the light entering position 41 of the scanning module 30 are aligned with each other. Therefore, just by manually or using a driving mechanism to move the position of the penetrating light source 70, JL · 乂 can make a first light source output 70A with a lower brightness and a second light source output 70B with a higher brightness separately The light entry positions 41 of the scanning chess set 30 are aligned with each other * to provide the light required by the scanner to capture positive and negative films. As shown in FIG. S and FIG. 9, the fifth embodiment of the scanner penetrating light source device of the present invention is different from the fourth embodiment in that the penetrating light source 70 is a light shielding sheet 75 Position, a first light source output 70A with a lower brightness and a second light source output 70B with a higher brightness are formed to provide the light required by the scanner for the positive and negative films, respectively. As shown in FIG. 8, the light-shielding sheet 75 is disposed below the light-emitting element 73, so that a first light source output 70A * M with a relatively low brightness can be generated to provide the scanning module 30 with the light required for the positive film. As shown in FIG. 9, the light-shielding sheet 75 can be rotated to the side of the light-emitting element 73 by manual operation or driven by a driving device (not shown), so the light-shielding M 75 no longer blocks the light of the light-emitting element 73. Therefore, a high-brightness second light source output 70B′M can be generated to provide the light required for scanning the 30 ′ group to take the negative. -9- This paper size is in accordance with China National Standard (CNS) A4 (210 X 297 mm) nn ί υ n I nnn —J 一 K ϋ n Order ---------- line "(please Read the meaning on the back of the page before filling in this page) A7 B7 03 Modified by the Economic and Intellectual Property Bureau Printed by the Consumer Cooperatives of the V.

Go to the position where the positive film is taken (as shown in Fig. 3 and Fig. 8), or move to the position where the negative film is taken (as shown in Fig. 4, plaque 15 and Fig. 9). After the light shielding plate 75 is moved to the correct position, the actual material reading process of the post M can be performed. As shown in FIG. 14, it is a control flowchart of the sixth embodiment of the present invention. The control procedure is to first determine whether the manuscript 20 being captured is a penetrating or reflecting manuscript. If it is a reflecting manuscript, the light source of the reflecting manuscript is turned on. 31, and use the reflective manuscript light source 31 to provide light; and when the captured manuscript 20 is a penetrating manuscript, the captured manuscript 20 is positive or negative, and when the captured manuscript 20 is positive , Light up the light emitting element 83A, and move the penetrating light source 80 to the correct position; when the manuscript 20 is negative, light up the light emitting element 83B * and move the penetrating light source 80 to the correct position, and then Carry out subsequent retrieval procedures. In addition, it must be emphasized here that although the penetrating light sources 70 and 80 of the above-mentioned embodiment of the present case both provide two light source outputs with different brightnesses for reading positive or negative image data. However, in practice, the present invention can also be modified to be designed to have two or more different light source outputs, so that the scanner can read positive, negative, and other different forms of penetrating manuscripts. In the present invention, the method of achieving the above-mentioned method for making the penetrating light source 70, S0 to have more than two light sources with different brightness is quite simple.
