New description: [New technical field] The present invention relates to a scanning device, and more particularly to a document scanning device that uses a transparent flat plate on a scanning device to reduce the invalid scanning range. [Prior Art] In the conventional zero-edge book scanner, in order to make the document located at the edge_area of the platform fall within the scannable range, the designer usually uses a charge-coupled device image sensor (Charge-coupled device, The CCD) optical module does not use a c〇ntact type image sensor (CIS) optical module to design a zero margin book scanner. The main reason is that the CCD-type optical module itself has a lens, and the CCD is transmitted through the lens, and the scanable range is fan-shaped, so that the document image of the edge region can be obtained. The light source of the CIS optical module is direct, and the position of the light source is a certain distance from the CIS itself, so that the scanning device has an invalid scanning area where the image cannot be obtained. 1 and 2 show a conventional CIS-type scanning device 100 and a schematic diagram. As shown in FIG. 1, the scanning device 1A includes a housing 11A, a transparent plate 120, and a CIS scanning module 13 ( ^The transparent plate 12〇 is mounted on the outer casing 11〇, in order to allow the structure of the outer casing to stably support the translucent flat plate 120, the transparent flat plate 12 is bulged into the outer casing. Since the cis scanning mode group 13 itself The structural limitation plus the thickness of the housing ιι〇 and the reason, the scanning module 1 3 〇 for the transparent plate! Μ There will be & effective scanning area 132 and an invalid scanning area (1), 3 M406»^ Lo in the invalid scanning area The portion of the original 〇 of 133 cannot be scanned by scanning -13〇, and the zero margin scanning cannot be achieved. As shown in Fig. 2, since the depth of field of the CIS scanning module is short, the design can be in the scanning device 100, and the CIS scanning module 13 A spacer 150 is added between the crucible and the transparent plate to allow the CIS scanning module 13 to slide on the lower surface of the transparent flat plate 12 by the spacer 150, and to make the cIS and the transparent plate j2 Maintain a fixed distance between each other. Interval = 150 is best 疋Sticking to the transparent plate 12〇, this limitation also causes the cis scanning module 130 itself to be further away from the edge of the transparent plate 12〇. Therefore, the scanning device of FIG. 2 has an invalid scanning area that is larger than the scanning device 100 of FIG. Invalid scan area 133, thereby reducing the effective scan area 132. · Combining the above original @, it can be known that the conventional scanning device of the Xiao (3) scanning module cannot achieve the purpose of zero margin scanning. Figure 3 shows the conventional CCD type scanning. A schematic diagram of the device 1 ", as shown in Fig. 3, 'this CCD type scanning device ι〇〇, the structure is similar to Fig. 1' except that the CCD scanning module 13 is used. As described above, the scannable range of the CCD image sensor is fanned out, so that the CCD scan module 130" can reach the maximum effective scan area 132. However, the disadvantage of the scan apparatus 100 is that the whole machine The platform is heavy and cannot achieve the characteristics of volume reduction and light weight. Therefore, the present invention provides a scanning device that reduces the invalid scanning range in order to solve the above problems. [New content] One of the novels The purpose is to provide a 4 Μ 4 υ〇 Ζ Ζ 扫 : : : : : : : : : : : : : : : : : : 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备 设备The invalid scanning range field device comprises a transparent plate and a scanning module. The transparent flat material has a chamfer. The transparent plate comprises a scanning plane and a chamfered surface formed by the chamfer for carrying the original. Cut: Adjacent. The scanning module is a movable floor facing transparent plate for scanning the original placed on the transparent plate. The following effects can be achieved by the scanning device described above. By using a transparent plate with chamfers, the alignment line of the original can be moved toward the center of the transparent plate, which reduces the invalid scanning range and even achieves zero-edge scanning. In addition, the non-to-be-scanned pages of the manuscript manuscript can be assisted by the chamfer of the transparent plate. This structure is not only suitable for the ccd type scanning module, but also for the CIS wire pure group, so that the (3) type scanning module can be more commonly used. Therefore, the scanning device can have the advantages of being light, thin, short, and small. In order to make the above description of the present invention more apparent, it will be described in detail below with reference to the accompanying drawings. [Embodiment] Figure 4 shows a schematic view of a scanning device according to a first embodiment of the present invention. Fig. 5 shows a partial enlarged view of a scanning device t according to the first embodiment of the present invention. As shown in FIG. 4 and FIG. 5, the scanning device 本 of the embodiment includes a transparent flat panel 1 and a scanning module 2A. The transparent plate ίο has a chamfer 13 at one end, and the corner of the chamfer 13 is 5 M406892 degrees A] can be any acute angle, for example, between 3 degrees and 60 degrees, the transparent plate 10 includes a scanning plane 14 and The chamfered surface 16 formed by the chamfer 13 is used to carry an original scanning plane 14 and the chamfered surface 16 adjacent to the β original document, in this embodiment, for example, a book, a file that can be opened and closed, etc. Limited to this. The original 〇 has - to be scanned page 〇 1 and - non-to-scan page 〇 2. Alternatively, the original document 〇 is a foldable document 'When the range of the original document 0 is larger than the effective scanning range 60 of the scanning device 1', the original document 〇 can be folded into a plurality of portions to be sequentially scanned. Since the portion close to the fold line is likely to be a very important part, it is necessary to reduce the invalid scan range and even eliminate the invalid scan range. The scanning module 20 can be moved to the transparent flat panel 1 to scan the original scanning module 20 disposed on the transparent flat panel 10 to provide a light source to illuminate the original web. In the present embodiment, the mode is scanned, and 20 includes a CIS image sensor. However, in other implementations, the scanning module 2 can include a CCD image sensor. The Sweeper includes "the side plate 3G, the platform housing 40 and the device 50". The side panel 3 is made of a metal material, a composite material or a plastic material. Side panel 3. The thickness is about 〇 5 faces between flat and 〇! The side panel 30 has a bearing surface 32 that abuts the transparent slit adjacent to the &^#心16 ‘Adjacency can be contiguous or non-sweeping. The carrier surface 32 and the chamfered surface 16 collectively carry the original defect; J 〇 2. In the present embodiment, the angle A2 at which the chamfered surface 16 is inclined is equal to the angle A3 at which the bearing surface 32 is inclined, that is, the slope of β is substantially equal to the slope of the bearing surface 32. Also, the chamfered surface 16 is mounted on the platform housing 40, the scanning module 20 6 M406892 is disposed in the platform housing 40, and the side panel 3 is mounted on the platform housing 40. The platform housing 4 includes a floor portion 42 for supporting the end of the transparent plate 10 at a level H. The support portion 42 is connected to the side plate 3A. In the present embodiment, the support portion 42 is integrally formed with the side plate 3 to form a metal outer frame which can be formed by punching. The interface 17 between the scanning plane 14 and the chamfered surface 16 (which may be referred to as the scanning starting point) is located at the edge 12E of the end 12 of the transparent plate 10 - inward (to the left in the drawing) at least the supporting portion 42 One of the width w bits. The spacer 50 is disposed on the scanning module 2A. When the scanning module 2 is moved, the spacer 50 slides against the support portion 42 to maintain a certain distance between the scanning module 2 and the original to obtain a reliable scanning result. It is to be noted that the spacer 5 左边 on the left side of Fig. 4 has a height greater than the height of the spacer 50 on the right side. Alternatively, two spacers 50 of the same size may be used as long as other structures can complement the thickness of the support portion 42.

As shown in Fig. 6, the present embodiment is similar to the first embodiment except that the angle VIII of the inclined plane 16 is substantially smaller than the angle 纟A3 at which the bearing surface 32 is inclined. Since the page 〇1 of the original document to be scanned is usually pressed on the scanning flat φ 14 , the scanning plane Μ provides the main supporting brown power to the original 〇, and the chamfered surface 16 and the side plate 30 can assist the original 〇, so The effect of this novel can still be achieved. The configuration of 13 makes the scanning plane 14 of 10, and the alignment reference line of the chamfered original 〇 of the transparent flat plate 10 can be moved to the center of the transparent flat plate 7 M406892, so that the page (1) (four) edge of the original 0 to be scanned can also be effectively scanned. Range 6". Moreover, the use of a thin metal frame to carry the transparent plate H)' allows the scanning module 2Q to move more toward the edge, thereby reducing the ineffective scanning range and even achieving the effect of zero margin scanning. In addition, the 'chamfer U can also assist the non-to-be-scanned page of the original ◦ 〇2. The surface of the metal frame is also relatively smooth so that the spacer 5 can slide at the bottom of the metal support 42 without sliding against the transparent plate. The inclination angle of the side 30 and the chamfered chamfered surface 16 can be adjusted to narrow the invalid scanning range, and even the invalid scanning range can be completely eliminated.
