See also Fig. 7.Described page turning control circuit 4 comprises that mainly one is arranged on first of page turning parts front portion and triggers on the frame that inductor 41, is arranged on the page turning parts the second triggering inductor 42 and an IC control module 43 that can contact from gear with off-centre; The output that described page turning triggers inductor, a rotation triggering inductor is electrically connected with the input of described IC control module; The control end of described IC control module is electrically connected with page turning work button on the guidance panel of scanner; The output of described IC control module is electrically connected with the drive motors, the electric fan of page turning parts, the induced-draught fan of air draught parts and the motor in the page turning accessory that rotate the platen parts respectively; The output of this IC control module also is electrically connected with the lifting drive motors of the book information portion of scanner and the shutter trigger switch of the image application parts mesoprosopy sensor in the scanner.
First trigger of page turning parts front end is connected with the IC control module, first of page turner front end triggers inductor and provides page turning and finish pulse signal and send into the IC control module, off-centre triggers the second triggering inductor from gear and provides the pulse signal that a rubber wheel is finished a revolution, provide one by the IC control module swinging mounting shifted out the control signal of scanning space, drive swinging mounting and outwards rotate.
When the IC control module receive only eccentric trigger from gear second trigger inductor and provide pulse signal after, start the second joint air intake electric fan work, strengthen intake; Next trigger the inductor pulse signal as receiving page turner front end first, confirm the page turning success; Move out scanning space when receiving the eccentric for the second time pulse signal rear drive swinging mounting that provides from the gear triggering second triggering inductor.The utility model also comprises a bracing frame 5 (seeing also Fig. 8 c), is used to support the swinging mounting that moves out scanning space.In addition, trigger inductor owing on frame, be provided with one second, off-centre whenever circles from gear, second triggers inductor provides a pulse signal, if the IC control module is not received first of page turner front end and is triggered the pulse signal of inductor, and when receiving second flop signal, the IC control module can provide a control signal and restart second electric fan enhancing intake (possible page or leaf paper is thick) for the electric fan control button control on the page turning parts, do not trigger the pulse signal of inductor if also receive first, the IC control module provides a control command, stop the information bracket drive circuit, provide scanning work and finish signal.
The course of action that the swinging mounting of automatic page turning device of the present utility model shifts out book information portion as shown in Figure 8, wherein to be the automatic page turning parts be pressed together on view in the book information portion by swinging mounting to a; B is the view that begin shift out book information portion of automatic page turning parts at swinging mounting; C is the view that automatic page turning parts pressing plate shifts out book information portion fully.
Please continue to consult Fig. 7.In the automatic page turning device of the utility model books pair of pages synchronous scanning instrument, also comprise a page turning misoperation warning circuit 49, be electrically connected that the output of this page turning misoperation warning circuit is electrically connected alarm element 491 with the output of described IC control module.Described alarm element can be a buzzer, or stroboscopic signal lamp.First of page turning parts front end triggers the induction sensor and provides page turning and finish pulse signal and send into the IC control module, off-centre triggers the second triggering inductor from gear and provides the pulse signal that a rubber wheel is finished a revolution, provide one by the IC control module swinging mounting shifted out the control signal of scanning space, drive motors work.
Trigger second when triggering the pulse signal that inductor provides when the IC control module receives only twice off-centre continuously from gear, it is that whole page turning work is finished that the IC control module is confirmed as; Or think and the page turning fault occurs, send the control alarm signal, prompting operation person.
The process of the utility model automatic page turning as shown in Figure 9, Fig. 9 is that the automatic page turning device of the utility model books pair of pages synchronous scanning instrument is installed in the automatic page turning action demonstration graph among a kind of embodiment of book information portion, and wherein a is that the automatic page turning device of the utility model books pair of pages synchronous scanning instrument is installed in book information portion structural representation; The dentation rubber wheel played the paper view when b was air-supply; The page that c is risen is dug the page view of leaving the page turning parts under the suction function of energy that air-supply is assembled and air; D is the view that the books page will soon open fully.
At first, according to the size of books by top groove and Lock Part with swinging mounting fixedly the page turning parts on swinging mounting.When the transparent glass pressing plate moves up or after book information portion moved down, swinging mounting moved driver part and by driving handle swinging mounting moved in book information portion widdershins.When the page turning parts contact the page face of book information portion, at the miniature touch-switch pressurized of swinging mounting bottom and conducting, the micromachine that starts on the page turning parts rotates, and motor-driven dentation rubber wheel rotates, page in the book information portion is arched upward, by the wind in the air outlet again and hike up.Owing to the opposite side at books is provided with the air draught nozzle component, above the V-type carriage, form a negative pressure space again, page is climbed over center line smoothly.When climbing over, page contacts the triggering sensor of bottom surface, swinging mounting end, its output signal make the transparent glass pressing plate begin to move down or book information portion on move, swinging mounting moves the driver part reverse drive simultaneously, the swinging mounting clockwise direction moves, and shifts out the scanner chassis space before the printing opacity pressing plate arrives the bottom.The transparent glass pressing plate is pressed on the scanned document of book information portion, the beginning scanning imaging system.Behind this page end of scan, transparent glass pressing plate and book information part from, repeat above-mentioned action again, finish until this subjob.
The utility model is rational in infrastructure, and reliable in action is little with page contact area; By the strength of blowing and the air draught of air draught parts, the negative pressure that air-flow produces in cabinet with the another side of the direct pressure-vaccum of the page to books, is finished automatic page turning during page turning, and whole page turning process does not have the machinery contact, and is fool proof.
