The actuating device 22 is connected to the movable guide 21, and when the upper cover 12 is closed with the flatbed scanning device 1, the movable guide 21 is rotated upward. In this preferred embodiment, the actuating device 22 is a magnetic member 2 21 mounted to the upper cover 12. When the upper cover 12 is covered with the flatbed scanning device 1 1 , the movable guide plate 2 1 can be rotated upward under the magnetic attraction of the magnetic member 2 2 1 'the limiting member located on the guiding wall 31 1 at this time. 24 abuts the movable guide 21 to ensure that there is sufficient clearance between the movable guide 21 and the guide wall 31 for the paper to pass. Conversely, when the user opens the upper cover 12, the movable guide 2 1 loses the attraction of the magnetic member 2 2 1 and descends back into the elongated groove 2 3 . Referring to the sixth figure, the user's automatic feeding by the automatic paper feeder 10 of the present invention is as follows. First, the user covers the upper cover 12 and the flatbed scanning device 1 to make the automatic paper feeder 1 〇 The scanning area 13 on the flatbed scanning device 11 is attached. Then, the paper is placed in the paper feed cassette of the automatic paper feeder 10; the paper placed in the paper feed tray is guided through the guiding path and sent to the scanning area 13 by the feeding of the paper feeding wheel 32. Scan in. At this time, the movable guide 21 is attracted by the magnetic force of the magnetic member 2 2 1 to rotate upward, and protrudes above the flat type scanning device 1 1 to form a slope ' and thereby guide the paper back to the feeding path 3 3 . Since the height of the rear end of the movable guide 21 is slightly higher than the guide wall 3 1, the paper passing through the scanning area 13 can be returned to the guiding path without being guided by the guiding guide 3 1 hindered. Referring to the seventh figure, as shown in the figure, after the user completes the scanning and lifts the upper cover 12, the movable guide 2 1 and the magnetic member 2 2 1 are far 1012038991-0 1012121# single number deletion 1 page 6 / Total 16 pages of money 42276 away. The movable guide 21 thus loses the driving force of the upward rotation and falls back into the elongated groove 23 'so that the upper surface of the flatbed scanning device returns to the complete plane again." In summary, the present creation and the conventional knowledge The technical difference is that a paper guiding mechanism 2 is provided at the upper surface of the flatbed scanning device 1 , and the paper guiding mechanism 2 Q includes at least an active gas guiding plate 21 and an actuating device 22 . The movable guide 2 1 is movably connected to the upper surface of the platform scanning device 1 and reciprocable along a predetermined path; and the actuating farm 22 is connected to the movable guide 21 'When the platform When the upper cover 12 of the scanning device 11 is closed, the movable guide 2 is moved upward, and the movable guide 2 1 is kept at an appropriate distance from the guide wall 31 on the feeding path 3 3 to prevent the occurrence of paper jam.
