[Technical field to which the creation belongs] The present invention relates to an automatic document feeder (ADF), and more particularly to an automatic document feeder equipped with a supporting plate on an elastic element in an inclined feeding E. [Prior art] 凊 Refer to FIG. 1A ', which is a sectional view showing the structure of a conventional automatic paper feeding device. In FIG. 1A, the automatic paper feeding device 100 includes a horizontal paper tray 104, an automatic paper feeding roller group 106, a paper tray 108, and a spring lu for feeding the paper to be fed 102 to the printer. , Photocopiers, scanners and fax machines (not shown in Figure 1A). The horizontal paper tray 104 is used to place the paper 102 to be fed, and the rim of the automatic paper feeding roller group 106 and the paper feeding pad 10 are adjacently contacted to form the feeding end 112, and the automatic paper feeding roller group 1 06 rotates clockwise around the center of the wheel shaft 116 to drive the paper to be fed forward. One end of the paper tray 108 is pivotally connected to the horizontal paper tray 104, so that the paper tray 108 can be rotated on the paper tray 104. One end of the spring 111 is fixed in the groove 113 of the horizontal paper feed £ 104, and the other end of the spring 111 is fixed under the other end of the paper tray 〇08, so that the paper tray 1 08 and the horizontal tray 104 There is an included angle Θ 1. Please refer to FIG. 1B, which is a structural cross-sectional view of an automatic paper feeding device in which a paper stack 丨 4 is placed in FIG. 丨 A. In Fig. 1B, the paper stack 114 is placed on the horizontal tray 104, and the paper stack 114 is the paper sheets 102a and 102b, the paper stack 114a, and the paper 102c from top to bottom, respectively. Because the gravity of the paper stack 114 is much greater than the gravity of the single paper to be fed 102 in Figure 1A,

TW1276-BF (虹光) .ptd Page 5 M252557 V. Creative Instructions (2) In the picture, the included angle between the 'Paperboard 108' and the horizontal tray 104 is smaller than the cool angle 01 in Figure 丨 A. Because the weight of the paper stack 114 is relatively heavy, the spring ui must be large enough to support the paper stack 丨 4 leading edge to the feeding pad 丨 丨 0, and the leading edge of the paper 10 2a just just resists the feed端 丨 12.

When the automatic paper-feeding roller group 106 successively drives the paper 102a, 102b, and paper 114a to feed the MFP completely, only the paper 102c is left on the horizontal tray 104. At this time, The situation is the same as in Figure 1A. Because of the upward elastic force of the spring ln, the f angle between the paper tray 108 and the horizontal tray 10 is increased to 01, which is used to push the paper 102c upwards so that the leading edge of the paper 102 (: Resist the feed end 112. Therefore, the automatic paper feed roller group 丨 〇6 can drive the paper 102c to the feed end 112 to complete the automatic paper feed step of the automatic paper feed device 100. However, due to the horizontal paper feed The box 104 is designed in a horizontal structure, and the spring 111 must provide an upward elastic force to overcome the weight of the paper, so that the paper support 108 can support the paper high, so that the front end of the paper is against the feeding end 1 丨 2. When the paper support As the number of papers supported by 1 0 8 increases, the spring force of the spring must also increase, so as to ensure that the top paper can resist the feeding end 112. Such a horizontal paper tray 104, The combined design of the impeachment u and the cardboard 108 is complicated because of its combined structure, so it is not easy to assemble in the production process. The cost is also relatively low. Please refer to Figure 2A, which shows the patent publication number of the Republic of China Structural cut-out of automatic paper feeding device 200 disclosed in 509 1 43 In Figure 2A, the automatic paper feeding device 200 includes an inclined paper tray 204, an automatic paper feeding roller set 206, and an elastic sheet (Mylar) 20 8 for feeding the paper to be fed 202.

The inclined paper feed tray 204 is used to place the paper to be fed 202, and the paper roll roller group 206 and the paper feeding pad 21 () are located at the bottom of the inclined paper tray 204 and the automatic paper feed roller group 206 The wheel edge is in contact with the paper feeding pad 21, and the paper feeding 212 is fed. In addition, the automatic paper feeding roller set 206 rotates clockwise with the wheel shaft 216 as the center to drive the paper 202 forward. The elastic sheet 208 is covered with ^ 口 2 0 8 a and the support part 208 b, the joint part 208 a is closely and flatly attached to the inclined tray 204, and the support part 208 b and the tilt There is an included angle between the paper trays 504/5 1 and the elastic sheet 208 supporting the more the amount of paper, the smaller the included angle between the supporting portion 208 b and the = oblique tray 204. The elastic sheet 2 08 supports the paper to be fed 202 by its own elastic force on the structure, and the tilted tray 204 is inclined, and the β of the structure is counted. The front end of the paper 2 to be fed will be caused by The gravity relationship slides down to the feeding end 212, so that the automatic paper feeding roller set 206 can drive the paper to be fed 202 to the feeding end 212. (2) Referring to FIG. 2B, a cross-sectional view of the structure of the automatic paper feeding device 200 with the paper stack 214 placed in FIG. 2A is shown. In Fig. 2B, we place the paper stack 214 on the inclined tray 204, where the paper stack 214 is paper 202a, 202b, paper 21a, and paper 202c from top to bottom, respectively. Because the downward gravity of the paper stack 214 is much greater than the gravity of the single sheet to be fed 200 in the second figure and is greater than the upward elastic force of the elastic sheet 20, at this time, the support portion 2j8b and the inclined paper tray 204 The included angle is smaller than yj}, which even causes the bottom surface of the supporting portion 20b of the elastic sheet 208 to contact the inclined paper tray 204. At the same time, the leading edge of the paper stack 214 is in contact with the feed pad 21o, and the leading edge of the paper 202 is just in contact with the feeding end 212. ., TW1276-BF (Rainbow) .ptd Page 2 M2557

When the automatic paper feed roller set 2 06 drives the papers 202a, 202b and paper ® 214a one by one and feeds them to the MFP, at this time, only the paper 2c is left on the tray 204_. The situation is the same as in Figure 2A. Because of the upward elasticity of the elastic sheet 208, the included angle between the support portion 208b and the inclined tray 2004 becomes cold J, which is used to push the paper 202c upward so that the leading edge of the paper 202c abuts住 feed end 212. Therefore, the automatic paper feeding roller group 206 can drive the paper 202c to the feeding end 212 to complete the automatic paper feeding process of the automatic paper feeding device 20 (). However, since the structure of the flexible sheet 208 itself is quite weak, and is directly exposed to the inclined tray 204, when the automatic paper feeding device 2000 is used for a long time, or the user is not careful Under operation, the elastic sheet 208 is easily damaged. Once the elastic sheet 208 is damaged, the automatic paper feeding device 208 cannot perform the normal paper feeding operation, and the user must also send the automatic paper feeding device 200 to the factory for repair, thus increasing the user's maintenance cost for the machine. [Creation content] = In view of this, the purpose of this creation is to provide an automatic paper feeding device. The design of the loading plate on the inclined tray can protect the loading. The elastic sheet below can be prevented from being damaged and the elastic sheet can be reduced. The damage machine 2 guarantees the service life of the elastic sheet and maintains the operating stability of the automatic paper feeding device. According to the purpose of this creation, an automatic paper feeding device including an inclined paper tray, a carrying plate and an elastic element is proposed, including tilting.

The downward gravity of Zhangfeng 314 is far greater than that of the sheet in Figure 3A—the paper to be fed 3002 is greater than the upward elastic force of the elastic sheet 3008. The included angle between the carrier plate 307 and the inclined inlet IE304 is smaller than the included angle ⑴ 丨 in FIG. 3A. Even the bottom surface of the supporting portion 30813 of the elastic sheet 308 is brought into contact with the inclined paper feed 304, and the bottom surface of the carrier plate 307 is in contact with one end of the joint portion 308a. At the same time, the leading edge of the paper stack 314 is in contact with the feed pad 31, and the leading edge of the paper stack is just in contact with the feeding end 3 1 2. When the automatic paper feeding roller group 306 starts to rotate around the wheel axis 316 as the center of the paper 30 2a contacts the feeding end 312, the rotation of the automatic paper feeding roller group 306 will move the paper 302a toward the feeding end 312. . Therefore, after Tian, Zhang and Zhang 302a are all driven by the automatic paper feeding roller group 306 through the feeding end 312, the upward elasticity of the elastic sheet 308 makes the leading edge of the paper 3002b contact the feeding end 3 12.
