Description of the invention () 5-1 Field of invention and background A. Field of invention • The present invention is a lamp tube transmission device, especially a rotary arm lamp tube transmission device built in the scanner, to Scan penetrating and reflective manuscripts. B. Background of the Invention Generally, platform scanners with the functions of scanning penetrating and reflecting manuscripts must be equipped with more than two lamp tubes, so that the light source comes from the lamp tubes above and below respectively. When scanning penetrating manuscripts, the light source comes from the lamp above. When scanning reflections, the light source comes from the lamp below. The reflected image is reflected by the mirror group to the image reading device, and the scanning operation is completed. The provision of such a light source has many disadvantages. For example, since two sets of lamp transmission devices are required, the structure is more complicated and the cost is higher. Moreover, the upper and lower two groups of lamp driving devices are separated separately, and only one group is active during scanning. If the penetrating and reflective manuscripts are scanned alternately, sufficient warm-up time is required. In addition, the volume of the two sets of lamp drive devices is also relatively large, and it is difficult to apply them to a photo drive with a relatively small volume.

Description of invention () ~~ Another purpose of the invention is to provide a single support The dual-purpose lamp transmission device of the lamp tube to reduce the use of the lamp tube and reduce the time for the lamp tube to warm up when switching between the reflection draft and the penetrating draft. Another object of the present invention is to provide a small-size, simple-structure dual-purpose lamp transmission device to facilitate the use of a cassette scanner. Based on the above purpose, the present invention is a rotary-arm lamp transmission device that can The rotating arm structure is used to control the rotation of the lamp tube, and the direction of the light source is adjusted. Therefore, as long as a single lamp tube is used, the penetrating and reflective drafts can be irradiated. The invention mainly includes: a lamp tube carrying device to provide a light source, and a rotary arm and a support arm are connected to both ends of the lamp tube. The rotating arm and the supporting arm are fixed on the bearing base. When scanning the reflected manuscript, the motor in the bearing base drives the rotating arm, which moves the lamp bearing device downwards, so that the light source reflects from below to the document. _When scanning penetrating manuscripts, the lamp carrier moves upwards so that the light source illuminates the document from top to bottom.

FIG. 4 is a side view of applying the present invention to a conventional transmission structure. 5-4 Detailed description of the invention Figure 1A shows a front view of the invention. As shown in FIG. 1, the rotary arm type lamp tube transmission device of the present invention mainly includes: a lamp tube carrying device 1 (Π, a lamp tube 102 is installed therein, and a group of reflectors 200 (see FIG. 1B). The reflector 201 is fixed in the lamp tube carrying device 101, and the position adjacent to the lamp tube 102 can change the direction of light source reflection as the lamp tube carrying device 101 rotates. Both ends of the lamp tube carrying device 101 are connected to The rotating arm 103 and a supporting arm 104. The main function of the rotating arm 103 is to control the direction of rotation of the lamp carrying device 101. The supporting arm 104 is responsible for supporting the lamp tube carrying device 101 when moving up and down. The rotating arm 103 consists of A gear set, see FIG. 1B, includes: driving gear 202, passive gear 203, idler 204, and grip wheel 205, and is connected and fixed by a connecting piece 206.

Description of the invention (rotate. At this time, the idler wheel 204 rotates clockwise and the connected grip wheel 205 rotates counterclockwise. Since the grip wheel 205 is fixed on the lamp carrier 101, the grip The rotation of the wheel 205 will cause the lamp carrier 101 to rotate with the yarrow. It should be noted that because the diameters of the four gears are not the same, the rotated position happens to make the lamp carrier 101 above the document. Make the reflector 201 above the lamp tube, so that the light source illuminates the penetrating manuscript from top to bottom. In addition, the reflector 201 can be replaced by a shading plate or a reflective plate to prevent light leakage. When the rotating arm is pushed up, it is inert The position of the wheel 204 happens to form a space between the lamp carrier 101 and the carrier base 106 to allow the document to pass through the middle. Similarly, when scanning the reflective manuscript, the driving gear 202 rotates counterclockwise, and the passive gear 203 Turn clockwise. The idler 204 rotates counterclockwise, and the connected grip wheel 20 turns clockwise. The result of the rotation happens to place the lamp carrier 101 in the document The reflective mirror 201 is located below the lamp tube, so that the light source illuminates the reflective manuscript from the bottom up. In this way, the present invention can scan the reflective manuscript and the penetrating manuscript using only a single lamp.

The document is placed on the document base 302. The document base 302 is made of transparent materials such as PC, glass, etc. When scanning, the lamp carrier 301 is located above the document base 302. When the entire carrier base When the base 3 03 moves, the document base 3 02 passes through the gap formed by the idler 3 04. The light source is irradiated from the top to the bottom, and then reflected by the mirror group 3 0 5 to the image reading device, such as CCD or CIS, etc. (Not shown in the figure), to convert the read image data into digital signals.

Description of the invention (1) Below the document base 4〇2. When the carrying base 403 moves, the document base 402 is passed by the lamp base 4〇3. At this time, due to the lamp The rotation relationship of the device 401 is such that the reflecting mirror 404 is located below the lamp tube 405, and the light source is irradiated from the bottom to the top. The reflected image of the document can be reflected to the image reading device (not shown) through the reflecting mirror group 406 The scanning operation is completed. The structure of the present invention is simple, so it can be built in the cassette scanner. FIG. 3A shows the situation in which the present invention is built in the cassette scanner when scanning the reflective manuscript. The present invention is installed on a ring-shaped transmission device 501, and moves in a synchronous and opposite direction with the image reading device 506. Reflective or penetrating drafts can be placed on the document base 502. The document base 502 is also made of transparent material to facilitate the passage of light. When scanning the reflective manuscript, the transmission device 50 1 moves the carrier base 5 07 in the direction of the document. The light source is below the document base 502. After the document is irradiated, it passes through the mirror group 5 0 3, 5 0 4, 5 0 5 50 $ reflected to the image reading device. Referring to Fig. 3B, in the same way, when scanning a penetrating manuscript, the rotating arm moves upward so that the lamp carrier 601 is located above the document base 602. The transmission device 609 moves the carrier base 608 in the direction of the document, and passes the document base 60 2 through the space formed by the idler 6 10. The reflector 603 illuminates the light source from top to bottom. The image of the penetrating document is reflected by the mirror group 604, 605, 606 to the image reading device 607, and the scanning operation is completed.
