There is an electrostatic adsorption force between the rotating conveyor belt and 8.
Since this does not occur, the winding operation and ejection of this document
The operation can be performed extremely smoothly. By the way, conventionally, as a holding and conveying device for sheet members, etc.
For example, air suction method, comb-teeth electrode and electric double layer method are used.
Devices based on electrostatic adsorption methods are known. It can also be used as a page turning device for book manuscripts. Devices using air suction methods have been proposed. However, each of these methods has its own limitations, which will be discussed later.
Books based on these methods have drawbacks such as
It is very difficult to put a manuscript page turning device into practical use.
Almost impossible. In other words, the air suction method generates negative pressure by suctioning air.
Requires an air pump to generate air and an air suction path.
This has the drawback of increasing the size of the device. In addition, the comb-shaped electrode embedding method uses two comb-shaped electrodes.
, embedded in the dielectric material so that each tooth meshes with the other.
, apply positive and negative voltages to each electrode.
This method not only increases costs but also reduces the quality of the manuscript.
It is possible to form the flip-up conveyor belt into an endless belt.
It becomes difficult. Furthermore, in the electric double layer method, corona discharge etc.
, charge the belt and seat with charges of opposite polarity.
Therefore, when turning the pages of book manuscripts, etc., use the
If you do not separate the coming pages in advance, they will be charged with electric charge.

It is moved up and down according to the thickness of the book original 92. As the page turning reading unit 1 rises, that is, as the thickness of the book document 92 increases, the tension of the turning conveyance belt 8 that drives it increases. Therefore, if the tension of this turning conveyor belt 8 becomes too high, that is, if the book document 92 is too thick and the page turning reading unit 1 rises too much, this tension acts as a brake, causing the page turning reading unit 1 to scan. become unable to do so. The scan cutoff sensor 34 detects the level at which the book document 92 is so thick that the page turning reading unit 1 cannot scan it. When this scan cutoff sensor 34 is ON,
Perform error processing 2 (turn on the warning buzzer and display the error message "Book manuscript is too thick"). When the user forcibly closes the transport section 19, the transport section 19
to prevent it from being damaged. Here, if the thickness of the book document 92 is less than the adaptation level, the user closes the transport section 19, thereby turning on the transport section lock sensor 31. At this time, if the transport section 19 remains open, that is, the transport section lock sensor 31 remains OFF, the abnormality processing 3

If the book size of 2 is detected and turned on, that is, the book size of the book original 92 set on the original placing surface 116 exceeds the reading area of the page turning reading unit 1 and is an unreadable book. In the case of the size, abnormality processing 4 (turning on the warning buzzer and displaying ``Book document size is too large'') is performed. After that, after checking the number of print positions, variable magnification, and number of pages to be turned, the prescan flag is set if the automatic book size recognition mode is selected.
Automatic book size m1! If it is not the mode, the book size input mode is entered, and the reading area of the book document 92 is determined by manually operating a predetermined key on the operation display board 313 to set the book size. When the start key 600 is pressed, the transport unit locking device 140 is activated, and the transport unit 19 is locked to the document table 18. By kneading, it is possible to avoid a situation where the user accidentally opens the conveying section 19 and damages the book original 92 during the page turning operation by the page turning reading unit. Next, this transport section locking device t! After operation of 140. If the prescan flag described above is set, the prescan operation of the page turning reading unit 1 is executed. Here, if the prescan flag is not set, this prescan operation is skipped. After this prescan operation, the connection fiN (printer 30

Then, when this connected device (printer 300) is ready, when it receives a reading start signal output from the connected device (printer 300), the page turning reading unit 1 is moved, and as described above, The reading operation of the manuscript picture of the book manuscript 92 is started. The reading operation by the page turning reading unit 1 is performed the number of times according to the number of print positions set previously.
It is done repeatedly. 2.When the predetermined number of reading operations are completed,
In order to read the document image of the next page, the page turning operation is executed by the page turning reading unit 1-1, as described above. In this way, the operation of reading the original image of the book manuscript 92 and the operation of turning the pages are repeatedly performed according to the preset number of pages until the last page is turned over. When the page turning operation for the preset last page to be turned is completed and the reading operation for the last read page is completed a predetermined number of times, the page turning reading unit 1 starts without performing the page turning operation for the last page to be read. , is returned to its home position 1-A, and this book document reading moto routine is returned. The basic operation of book manuscript reading mode is 1 or more 33rd
The flowchart shown in the figure shows the above-mentioned 2-page spread continuous reading mode, its double-sided mode, and 1-page spread reading mode!

The two-page spread continuous reading mode will be explained. In FIG. 34, when the start key 600 of the operation display board 313 is pressed and the reading start switch SW is turned on, a shutter (not shown) in the first reading sensor unit 9 is closed. The inner surface of this shutter is a white reference plate, which allows shading correction of the first reading sensor unit 9 to be performed. This shading correction is performed every time the page turning reading unit 1 starts up, and is completed before the moving speed of the page turning reading unit 1 reaches a constant speed (the timing chart for this part is not shown). The page turning reading unit 1 is started by a normal rotation start signal sent from the main control board 310 to the turning unit movement control board 312. In response to this normal rotation start signal, the page turning reading unit 1 starts pre-scanning. Here, after the moving speed of the page turning reading unit 1 rises to the constant speed Vf, the aforementioned shutter has already been opened, and the first CCD 315 detects the book original 92.
Reading of the original image has started. By reading the pre-scan of the page-turning reading unit 1, the edges of the spread book document 92 are detected by image processing, and the output of the encoder 152 attached to the turning roller 2 at this time is counted. , the book manuscript 9 set on the manuscript placement surface 116
2 book size! ? ! Then, the document image reading area of the page turning reading unit 1 and the page turning area are determined. In this way, this MFDS is configured such that the book original 92 is set with the center of the original placing surface 116 as a reference, so that the set book original 92
By detecting only the left edge of the page turning reading unit 1. reading area of the original image, and
The page turning area can be calculated. Therefore, in this MFDS, when detecting the book size of the book original 92, there is no need to pre-scan the entire page with the page turning reading unit 1. By simply performing a short press scan of the page turning reading unit 1, the book J placed on the document placement surface 116 can be read.
The book size of liI92 can be detected. As a result, during pre-scanning by the page-turning reading unit 1, the reading start page of the book M manuscript 92 is not erroneously turned over. The book size data of this book manuscript 92 is stored in the main control board 310 and the printer 3 as an externally connected device.
00. On the other hand, while this book size detection is completed and the book size data is being sent to the printer 300, the main control board 310 causes the turning unit drive control board 312 to reverse the turning unit park movement motor 60. A reversal signal is given, and the page turning reading unit 1 moves to its home position 1 at a speed Vr.
- It is moved back towards A. Note that the document placement surface 1 of the document table 18 of this MFD
16 in a chromatic color, such as yellow, which is not often used for book manuscripts, it is possible to read the manuscript images of this manuscript placement surface 116 and the book manuscript 92. Since the region identification accuracy can be improved, the book size can be detected more accurately during the pre-scan described above, and the reliability of the book size data is improved. Also, here, manuscript tif1. For example, the haze surface 11G is
If it is colored in a neutral color such as gray, it can be used as the first CCD 315 of the first reading sensor unit 9. Area identification during pre-scanning is possible without using a color sensor. After the above-mentioned pre-scan is completed and the page turning reading unit 1 is evacuated to the home position 1-A, the printer 300 is ready, and the main control board 310 is sent from the printer 300. When a transfer request signal requesting data transfer is given,
As a result, the main control board 310 gives a normal rotation signal to the turning unit movement control board 312 to rotate the turning unit movement motor 60 in the normal direction, and the normal rotation operation of the page turning and reading unit 1 is started. . As mentioned above, this page turning reading unit 1 has the following features:
By feeding back the output of the encoder 152 of the turning roller 2, the turning roller 2 is moved along the document surface of the book document 92 toward its end position 1-0 while being controlled at a constant speed Vf. . At this time, the L E D of the first reading sensor unit 9
316 is already lit, and the first CCD 315 of the first reading sensor unit 9 has started reading the document information of the book document 92. Here, as shown in FIG. 1, the document surface is severely warped near the binding part (part of the center) of the book Ms92, which is set with a nine-page spread on the manuscript paper surface 11G. It becomes difficult to read information accurately. Further, normally, manuscript information such as characters and images is not formed near the binding portion of the book manuscript 92. Therefore, in this MFDS, as shown in FIG. 34, the first CCD 3
15 reading 5FGATE is turned off, and reading of Mv5 information near this binding section is masked. As mentioned above, the mask area at the time of initial setting of this document information is +
It is set to be 10 kaku, -10 mwn,
The setting value of this mask area can be changed manually using the book binding mask area setting key 608 on the operation display board 313, so that it can also be used for book manuscripts with special bindings. There is. By the way, the first reading sensor unit 9 reads the document information of the book document 92 until the page turning reading unit 1 reaches its end position 23rd position 11i1-C.
When it reaches near the center of the book manuscript 92, the first
High voltage power supply 320 is turned on at frequency f1. As a result, the above-mentioned charge pattern is formed on the portion of the turning conveyor belt 8 that comes into contact with the right page of the book original 92. As described above, this turning conveyor belt 8 is not disturbed when the page turning reading unit 1 is being driven, and functions to hold down the book document 92. In this way, the page turning reading unit 1 is driven to its end position 1-C, and when the reading of the document information up to the reading area at the right end of the book document 92 is completed, the second high voltage is applied to the source 320. At the same time as the output is turned off, a turning signal is given from the main control board 310 to the turning unit failure control board 312, and the book manuscript 9 is read by the page turning reading unit 1.
The second page turning operation is started. At this time, if the document surface read by the first reading sensor unit 9 corresponds to the last read page of the book document 92 set in advance, the main control board 310 does not output a turning signal. After the page turning reading unit 1 finishes the final reading of the book original 1i 192, it is returned to its home position 9 without performing the above-mentioned page turning operation.
It is evacuated to the 1-in position 1-A. During the page turning operation of the book manuscript 92, the reverse operation of the page turning reading unit 1 starts at a slow speed until the page turning resensor 29 is turned on. Book manuscript 9
Page 2 (the right page in FIG. 1) that has been read is led into the page storage section 7. Then, the page turning reading unit 1 is further moved back toward its home position 1-A, and up to the center part of the page of the book document 92 that has been read is turned over into the page storage section 7. In addition, during the page turning operation of the page turning reading unit 1, the first high voltage power supply 320
is turned on at frequency f2. In this way, the page of the book manuscript 92 that has been turned into the page storage section 7 of the page-turning reading unit 1 is read after the page-turning reading unit 1 passes a part of the center of the book manuscript 92. While reaching the end position 1ii1-C, the page is ejected from the page storage section 7, and the page turning operation is completed. Page turning reading unit 1 when this page is ejected
The return speed Vrm is set so that it is larger than the speed Vf when reading the document, that is, V r
It is set so that m>Vf, and this page turning operation is made faster. The state of this series of page turning operations is detected by a page turning resensor 29. That is, this M F D S is 0 of the page turning resensor 29 at each position of the page turning reading unit 1.
The presence or absence of an abnormality is detected by checking N10FF, and if an abnormality exists, an abnormality processing operation is executed. This abnormal processing operation includes activating a warning buzzer, and, for example, if the document page cannot be turned into the page storage section 7, "page turning is not possible" and the document page turned over into the page storage section 7 is displayed. If the page cannot be ejected, a message such as ``Page stacking not possible'' will be displayed on the operation display board 31.
3, and furthermore, this page turning operation is stopped. Further, in order to enable the user to confirm the page turning state in which this abnormality has occurred, the location where the abnormality has occurred in this page turning state is displayed on the operation display board 3]3. Hereinafter, the reading of the second and subsequent pages of the book manuscript 92 and the page turning operation are started M times in response to a transfer request signal from the printer 300, and the reading operation and page turning operation similar to those described above are started. , is repeatedly executed until a preset final read page is reached. Here, in the timing chart of FIG. 34, when the number of print positions of the original is set to "1", that is, each read page of the book original 92 is read once, and the page that has been read is turned over. As shown above, the number of print positions for this document is "2".
”, when the first document reading operation by the first reading sensor unit 9 is completed, the turning unit 5! A reversal signal is sent to the motion control board 312 instead of a turning signal, and the page turning reading unit 1 is returned toward its home position [1-A] at a speed Vr, and this return operation At the same time as the page turning reading unit 1 is finished, the second original reading operation of the page turning reading unit 1 is started. Then, the document reading operation of the page turning reading unit 1 is repeatedly executed as many times as the number of document print positions set in advance, and when the number of times of this operation matches the number of print positions, the document is read for the first time. A turning signal is transmitted from the main control board 310 to the turning unit movement control board 312, and the above-described page turning operation is executed. Hereinafter, the reading of the second and subsequent pages of the book manuscript 92 and the page turning operation are sequentially started in response to a transfer request signal from the printer 300, and the reading operation is performed a number of times according to the number of print strokes as described above. Then, the page turning operation is repeatedly executed until the preset f&, the last read page is reached. Also, here, by the print magnification key 614. When the scanned original image is set to be scaled, the scan speed Vf of the first reading sensor unit 9 is varied to a speed corresponding to the scale ratio, so that the sub-image of the original image is In addition to scaling in the scanning direction, the first image processing board 314 also scales the original image in the main scanning direction. On the other hand, in the double-sided mode of the two-page spread continuous reading mode as described above, in order for the printer 300 to print both sides of the original image, the timing at which the transfer request signal is transmitted from the printer 300 to the main control board 310 is delayed. The difference is that there is a slight delay, but other operations are the same as in the two-page spread continuous reading mode described above. Next, with reference to FIG. 35, the one-page spread reading mode will be described. This one-page spread reading mode is. There is a mode in which the left page and right page of the spread-sheet book manuscript 92 are read separately and image formation is performed, and a mode in which each of these images is printed on separate transfer paper, and a mode in which the images are printed on the front and back sides of a single sheet of transfer paper. There is a printing mode (double-sided mode of this one-page spread reading mode). In this mode, either one of the operations of reading from the left page of the book manuscript 92 and the operation of reading from the right page is manually selected using the reading start page selection key 603 on the operation display board 313. Can be set. FIG. 35 shows a timing chart when reading starts from the left page of the book manuscript 92. The operation of this one-page spread reading mode is approximately the same as the operation of the double-sided mode of the two-page spread continuous reading mode described above. A transfer request signal is sent to the main control board 310 for each page, and this causes the page turning reading unit 1 to move at a constant speed from the left page to the right page of the book document 92. (scanned). FIG. 36 shows a timing chart when reading is set to start from the right page of the book original 92 in this one-page spread reading mode. As is clear from the second timing chart. When reading starts from the right page of the book [492], the moving speed of the page turning reading unit 1 for the left page, which is not read, of this book document 92 is the same as that of the first reading sensor unit 9 for the right page.
The scan speed is programmed to be faster than the scan speed Vf of An attempt is being made to shorten the time required to read a g-document, that is, to improve the performance of the reading function. Further, in this one-page spread reading mode, if a page is set to be skipped without being scanned using the reading skip page setting key 618. The page turning reading unit 1 for this reading skip page is moved at a speed faster than the scanning speed Vf of the first reading sensor unit 9 when reading, so that the turning operation for this reading skip page is immediately executed. (timing chart not shown). By the way, in general, as shown in FIGS. 35 and 36, there are few printers in which the printer 300 can continuously request a transfer request signal from the main control board 310 in a normal state. Therefore, when using such a general printer to perform this two-page spread/page separation reading mode, this can be achieved by feeding two sheets of transfer paper in a stacked manner on the printer side. can be done. In addition, if it is necessary to provide a certain distance between these two sheets of transfer paper due to the registration between the transfer paper and the photosensitive drum, the left page of the book manuscript 92 may be This is achieved by transmitting the image data on the right side of the book manuscript 92 to the printer as is, and delaying the transfer timing of the image data on the right page side of the book manuscript 92 to the printer by a time corresponding to the distance between these transfer sheets through a delay memory. can be done. A block diagram of an example of the latter case is shown in FIG. 37, and a timing chart thereof is shown in FIG. 38. In this example, internal gates A and B on the main control board 310 control the image data that is output to the printer through the delay memory for a time Td, with respect to the image data that is output as is to the printer through the switch. Configured to be delayed. Next, the double-sided mode in this one-page spread reading mode will be explained. First, a case will be described in which the image data of the two left and right pages of the spread book yK draft 92 are printed on the front and back sides of one sheet of transfer paper. In this case, it is necessary to reversely convey the transfer paper on the printer 300 side, so there will be a slight delay between printing the image data of the left page and starting printing the image data of the right page. It takes time. Therefore, in this mode, the page turning reading unit 1 finishes reading the left page of the book manuscript 92 and reaches the vicinity of the binding section. The drive of this page turning reading unit is temporarily stopped. Then, print 1 of the left page image on the printer 300 side
-2 and the reversal conveyance of this transfer paper is completed. When a transfer request signal is issued from the printer 300 to the main control board 310, the page turning reading unit 1, which had been stopped, is moved again at a predetermined scanning speed Vf.
The right page of the book manuscript 92 is read, and the image data of this right page is transferred to the printer 300.
On the back side of the transfer paper with the left page image printed on the front side,
This right page image is printed, and double-sided printing is performed. A timing chart at this time is shown in FIG. Next, a double-sided mode will be described in which an image is formed by matching the relationship between the front and back sides of the printed transfer paper and the front and back sides of the document surface of the book original 92 in this one-page spread reading mode. In this mode, when starting reading from the left page of the book document 92, as described above, the printer 300 is instructed to continuously feed two sheets,
The transfer paper with the right page image printed on it is ejected as is, while the transfer paper with the right page image printed on it is reversely conveyed, and the left page image of the next page of the book manuscript 92 is printed on the back side of the transfer paper. Make preparations. During this time, the MFDS side performs a page turning operation for the document page that has been read. When this page turning operation on the MFDS side is completed, 1
A reading operation for the next page is executed, and the read left page image is printed on the back side of the transfer paper on which the right page image was previously printed and is then reversely conveyed and then discharged. Further, the right page image read at this time is printed on newly fed transfer paper. This transfer paper, like the previous transfer paper, is conveyed in one reversal,
Preparations are made to print the left page image of the next page of the book manuscript 92 on the back side. By repeating this series of operations, Book 7$1i1! Transfer paper on which a document image with a page structure exactly similar to that of i92 is printed is obtained. The above is an example of the operation in the book document reading mode. Here, setting of a book document in the double-page spread reading mode will be explained. In the connected device check in FIG. 29, the printer 300
If the backside paper can be ejected, the following display will be displayed. Namely. If the manuscript is written horizontally (left-handed), open the first page you want to read and place it face up. If the manuscript is written vertically (right-handed), open the first page you want to read and set it upside down. For example, when writing a book manuscript horizontally or vertically,
t is also instructed on how to set it. On the other hand, in the connected device check of FIG. 29, if the printer 300 is capable of only front surface ejection, the following display will be made. Namely. ``If the book manuscript is written horizontally (left-handed), open the last page you want to read and set it upside down.' ``If the book manuscript is written vertically (right-handed), open the last page you want to read with the last page facing forward. Cent upwards. '', instructions are given for how to set the book manuscript horizontally and vertically. In this MFDS, by setting the book manuscript 92 according to the instructions described above, the book manuscript 92 can be connected to the Regardless of the function of the printer 300, it is possible to align the pages of the ejected transfer paper.Furthermore, there are two methods for inputting the number of pages to be turned in this MFDS: manual input using keys on the operation display board 313; There are several input methods, and the user can select one of these input methods according to his/her preference.One of these input methods is to press the reading total page setting key 60.
6, etc. to set the total number of pages you want to read.Another input method is to use the reading start page setting key 604, the reading last page setting key 605, etc. to set the first page you want to read. , is the method of inputting the last page. The number of pages to be turned in this MFDS may be input by any of the above methods, as long as the number of times the page is turned by the page-turning reading unit 1 can be calculated accurately. Hereinafter, a method of calculating the number of page turns in each of the above-mentioned methods will be explained. First, the case where the total number of pages to be read is input will be explained. Here, let X be the total number of pages you want to read and M be the number of pages you want to turn. When reading from the left page. (X, -2)/2=M remainder... ■When reading from the left page, (X-1)/2=M remainder...■ From these formulas, the value of M By calculating , the number of turns can be obtained. Next, the case where the first page and last page to be read are input will be explained. Here, select Y for the first page you want to read and 2 for the last page.
If the total number of pages you want to read is X, then X=Z-Y+1...■ By substituting this 0 formula into the above formulas ■ and ■, you can calculate the number of turns M. I can do it. By the way, this MFDS, as mentioned above. A single device is configured to be able to selectively read a book document and a sheet document and form images thereof. The image reading mode for book originals is as described above, and the image reading mode for sheet originals in this MFDS will be explained below. As shown in FIG. 31, this sheet document reading mode includes a sheet document through mode. There are a sheet original scanning mode and a sheet original manual opening/closing mode. First, the sheet document through mode will be explained. This sheet document through mode includes a five-sided document reading mode and a double-sided document reading mode, and this double-sided document reading mode includes a same-position reading mode and a different-position reading mode. Selection of these modes is performed as shown in FIG. First, in the single-sided original reading mode, FIG. 41 and
As shown in FIG. 42, a sheet M document 200 is set facing downward on the sheet document tray 94. As shown in FIG. In this state, when the start key 600 is pressed, first,
The power of the turning conveyor belt temporary movement motor 61 is turned on, the beating roller 12 is rotated, and the turning conveyor belt 8 is rotated. At this time, if there is no abnormality in each sensor and each input data, the paper feed is started. When the clutch 128 is turned on, the ji@paper roller 96 is rotated from the second paper feed pulley 130 attached to the first belt support roller 97 via the paper feed drive belt 127, and the sheet document 200 is fed. It is transported toward the bad 95. This paper feed separation pad 95 separates the lowest one sheet original 200 from other sheet originals, and
Conveyance guide 108 and the second! The paper is conveyed to the seventh position where it contacts the conveyor belt 8 without being guided by the second conveyance guide 109.
6 is attached, and by this paper feed sensor 2G,
The conveyance timing of the sheet original 200 is set so that the paper feed clutch 128 is turned off after the trailing edge of the sheet original 200 is detected. On the other hand, during this time, along with the rotation of the turning conveyor belt 8, a high AC voltage is applied to the second bias roller 11 from the AC power supply 35, and a striped charge pattern is formed on the turning conveyor belt 8. As a result, the fed sheet document 200 is attracted and conveyed by the turning conveyance belt 8. At this time, the linear speed of the turning conveyor belt 8 is 3 at the same magnification.
60 guns/s, and when changing magnification, it changes according to the set magnification. On the other hand, in the second mode, the page turning reading unit 1 is located at the end position 1i-c, and the first reading sensor unit 1-9 detects the sheet document 200 conveyed by the turning conveyor belt 8. Information is read out sequentially (pixel density is 400 dpi). After this reading, the sheet original 200 is transferred to the third feed guide 110 and the fourth facing roller 1o3. Fifth opposing roller 104. Sixth opposing roller 105. The paper is nipped and conveyed by the seventh opposing roller 106 and discharged from the paper discharge port 117 onto the paper discharge tray 23 . A paper discharge sensor 28 is attached to the 311!3rd feed guide 110 near the paper discharge [:] 117, and detects a paper discharge jam of the sheet original fgJ200 to be discharged. When the reading operation of the first sheet original 200 is completed, the paper feed clutch 128 is turned on again at a predetermined paper feeding timing, and the second sheet original 200 is read.
is fed, and a reading operation similar to that described above is performed. In this way, the sheet originals 200 that have been inserted into the sheet original tray 94 are sequentially fed and read, and when the last (top) sheet original 200 is fed and the sheet original sensor 25 is turned off, , second bias roller 1
1 is switched to a high-frequency AC voltage, the charge pattern on the turning conveyor belt 8 is neutralized, and after this final sheet document 200 is ejected, all operations of the MFDS are stopped. The reading operation described above is an operation when a printer with this MFD S1: back side ejection function is connected, and as a result, the sheet original vJ200 and the printed and sloping transfer paper are page aligned and ejected. is realized. Here, if the printer connected to this MFDS has only a front side ejection function, set the sheet original 200 facing north on the sheet original tray 94, and then By reading the sheet original 200, page-aligned ejection of the sheet original 200 and the printed transfer paper is realized, as in the case of the printer having the above-mentioned face-up ejection function. Further, the other operations when a printer with the front side paper ejection function is connected are the same as when a printer with the back side paper ejection function is connected. Next, the double-sided document reading mode in this sheet document through mode will be described. In this double-sided document reading mode, a horizontally written sheet document is set on the sheet G document T-ray 94 with the leading edge of the document facing downward. This is because the first reading sensor unit 9 and the second reading sensor unit 14 do not have memory.
This is because only mirror inversion in the main scanning direction can be used. First, the basic operation of the same-position reading mode in this double-sided document reading mode is shown in FIG. And, as shown in FIG. 44, this is the same as in the case of the 5-sided original reading mode, but in this mode. The page turning reading unit 1 is located at its home position fil-A, and the document information on both the front and back sides of the sheet document 200 is read at the same position as the second reading sensor unit 14 on the document table 18. , these first reading sensor units 9. and is simultaneously executed in parallel by the second reading sensor unit 14. On the other hand, the basic operation of the alternate position reading mode in this double-sided original reading mode is the same as that of the single-sided original reading mode, as shown in FIGS. 45 and 46. Unit 1 is located at its end position 1-C. As is clear here, in this separate position reading mode, the distance between the reading positions of the first reading sensor unit 9 and the second reading sensor unit 1.4 is larger than the length of the maximum size document. Document information on both the front and back sides of the sheet document 200 read by the first reading sensor unit t-9 and the second reading sensor unit 14 is output in time series. Next, the sheet scan mode in the sheet document reading mode will be described. In this sheet scan mode, Fig. 47 and Fig. 4
As shown in FIG. 8, a sheet original 200 is set on the sheet original tray 94 facing upward. When the start key 600 is pressed in this state. First, the power of the turning conveyor belt beating motor 61 is turned on, the drive roller 12 is rotated, and the turning conveyor belt 8 is rotated.
is rotated. At this time, if there is no abnormality in each sensor and each input data, the paper feed clutch 128 is turned on, and paper is fed from the second paper feed pulley 130 attached to the first belt support roller 97 via the paper feed drive belt 127. Paper feed roller 96 is rotated, and sheet document 200 is conveyed toward paper feed separation pad 95 . This paper feed separation pad 95 separates the lowest one sheet original 200 from other sheet originals, and
While being guided by the Wi feed guide 108 and the second #1 feed guide 109, the sheet is conveyed to a position in contact with the turning conveyor belt 8. Here, a paper feed sensor 26 is attached to the second Wi feed guide 109, and after the paper feed sensor 26 detects the trailing edge of the sheet document 200, the paper feed clutch 128 is turned OFF. So, sheet manuscript 200
The transport timing is set. On the other hand, during this time, along with the rotation of the turning conveyor belt 8, a high AC voltage is applied to the second bias roller 11 from the AC power supply 35, and a striped charge pattern is formed on the turning conveyor belt 8. As a result, the fed sheet document 200 is attracted and conveyed by the turning conveyance belt 8 . The linear speed of the turning conveyor belt 8 at this time is 360 rr
m/s is set at 9, and when the leading edge of the sheet document 200 reaches the home position fill-A,
Rotation of the turning conveyor belt 8 is stopped. On the other hand, in this mode, the page turning reading unit 1 is located at its home position 111-A,
After the rotation of the page-turning conveyor belt 8 is stopped, the page-turning reading unit 1 is moved toward its end position 1-C by the reunit drive motor 60, while its first reading sensor unit 9 , sheet document 2 conveyed by the turning conveyor belt 8
00 original information is read sequentially (pixel density is 400
dpi). When reading this document information, the first bias roller 3
Then, a high frequency AC voltage is applied by the 18th high voltage power supply 320, and the charge pattern formed on the turning conveyor belt 8 is neutralized. This prevents the sheet document 200 from entering the page-turning reading unit 1 when the page-turning reading unit 1 is moved back. After the page turning reading unit 1 has finished reading the sheet original 200 in this way, the page turning reading unit 1 is at its home position 1! It is returned towards l-A. Also, when the page turning reading unit 1 returns, the first reading sensor unit 9 reads the sheet document 200.
At the same time, a high-voltage AC voltage is applied to the first bias roller 3 from the first high-voltage power supply 320, and a striped charge pattern is formed on the turning conveyor belt 8. The paper is turned over and is attracted to the conveyor belt 8 and fixed. After the above-described operation is repeated the set number of times, the turning conveyor belt drive motor 61 is turned on, the turning conveyor belt 8 is rotated, and the sheet document 200 that has been read is delivered to the paper ejection port. 117 to paper output tray 2
The paper is ejected onto 3. In the third conveyance guide 110 near this paper ejection port 117,
A paper discharge sensor 28 is attached to detect a paper discharge jam of the sheet document 200 to be discharged. When the reading operation of the first sheet original 200 is completed, the paper feed clutch 128 is turned on again at a predetermined paper feeding timing, and the second sheet original 200 is read.
is fed, and a reading operation similar to that described above is performed. In this way, the sheet originals 200 set in the sheet original tray 94 are sequentially transported and read, and when the last (top) sheet original 200 is fed and the sheet original sensor 25 is turned off, the second Bias roller 11
After the power source of the MF is switched to the high-frequency AC voltage of the second high-voltage electric M321, the charge pattern of the turning conveyor belt 8 is neutralized, and this final sheet document 200 is ejected, the MF
All operations of the DS are stopped. Next, the sheet 1-manual document opening/closing mode in this sheet document through mode will be described. As shown in FIGS. 49 and 50, the operation of this sheet document manual opening/closing mode is performed by turning off each power source for the sheet conveying means and sheet suction in the sheet document scanning mode described above. In this state, the sheet originals are replaced manually by the operator. The operation control of the page turning reading unit 1 in this MFDS will be explained below. 5 shows an operation control circuit for the page turning reading unit l in this MFDS. This operation control circuit performs reciprocating active control of the page turning reading unit 1 and its speed control, and is incorporated into the turning unit drive control board 312. In FIG. 51, a microcomputer 520 (hereinafter simply referred to as microcomputer) also performs mode control and sequence control of this MFDS (details are not shown). As such a microcomputer 520, for example, μPD7
Programmable interval timer 5 with 1054G
21 (hereinafter simply referred to as a timer) is connected. This timer 521 is for sending out a pulse width modulated PWM output for controlling the speed of the turning unit drive motor 60 (DC motor) under the control of the microcomputer 520. The period of this PWM control is 50 (μ5ec),
This is controlled with a resolution of 400 bits. This timer 521 is connected to an 8 MHz oscillator 522 and is configured to receive a clock signal. Further, the turning unit drive motor 6o is driven by a microcomputer 52.
0, the driving transistors Q, ~Q. connected via. That is, when the transistors Q, , Q, are ON and the transistors Q, , Q, are OFF, a current is supplied to the turning unit drive motor 60 to rotate clockwise (CW), and the transistors Q, , Q . is ON and transistors Q,,Q, are OFF,
The turning unit drive motor 60 has a counterclockwise direction (CC
W) is supplied with a rotating current. Here, the turning unit drive motor 60 is rotated clockwise (
CW), the page turning reading unit 1. is set to move forward, and when the turning unit drive motor 60 rotates counterclockwise (CCV), the page turning reading unit 1 is set to move backward. The rotation direction of this turning unit drive motor 60 is determined by the port PF6 of the microcomputer 520. It is controlled by the CW multiplied signal and the CCW signal respectively output from the PF7. Further, an encoder 152 that generates pulses according to the rotation of the turning roller 2 is directly connected to the turning roller 2. Here, the encoder 152 generates two pulse signals with different phases depending on the rotation amount and rotation direction of the knit drive motor 60. One is the A-phase encoder pulse ENCA, and the other one is the A-phase encoder pulse ENCA.
One is the B-phase encoder pulse ENCB. The human phase encoder pulse ENCA is input to the counter input terminal C3 of the microcomputer 520 via the frequency division multiplexer 524. As a result, the microcomputer 520 determines that the pulse interval of the A-phase encoder pulse ENCA is determined by the internal counter of the microcomputer 520 (the oscillation frequency of the oscillator 525 of the microcomputer 520 is 10
MHz). In addition, the input signal to this counter input terminal C]- is 1 interrupt input, and during the processing of the interrupt program, the value of the measurement data of the pulse interval of the A-phase encoder pulse ENCA is read, and based on this data, , calculation of the number of revolutions of the turning unit drive motor 60, calculation of the motor control amount by proportional/integral control calculations, and output (loading data to the timer 521). Specifically, the output of the A-phase encoder pulse ENCA is divided into 1, 1,
By dividing the frequency by 2.4.8, an interrupt input signal is provided to the counter input terminal C1. Here, when the frequency is divided by 1, the first reading sensor unit 9
However, by one pulse of the encoder 152, it becomes 0.116
(2) By moving, the speed is calculated inside the microcomputer 520 according to the interrupt interval. Then, the output timer value is determined by proportional/integral calculation processing based on the calculated speed data. In addition, the A-phase encoder pulse ENCA, and. The B-phase encoder pulse ENCB is the flip-flop 5.
26 to the input terminal PC3 of the microcomputer 520, the phase difference between the two is detected, and the direction of rotation of the turning unit drive motor 60 is determined based on the phase difference. That is, the rotational direction of the turning unit drive motor 60 is determined by inputting the state of the B-phase encoder pulse ENCB at the rising edge of the A-phase encoder pulse ENCA to the port of the microcomputer 520. Next, speed control of the turning unit drive motor 60 will be explained. The speed control of this turning unit drive motor 60 is PWM.
done by control. First, when the page turning reading unit 1 scans the scanner,
That is, when the turning unit drive motor 60 rotates clockwise, the transistor Q is turned on, and the gate 527 is turned on by the PWM output from the timer 521.
The transistor Q is made 0N10FF through
A potential difference is generated between both terminals of the reunit drive motor 60, and the flipping unit immediate action motor 60 is rotated at a speed corresponding to the duty ratio of the PWM signal. On the other hand, when the page turning reading unit 1 returns,
Contrary to the above case, the transistor Q is turned on, and the PWM output from the timer 52 causes the transistor Q to become By generating a potential difference in the direction, the turning unit drive motor 60 is rotated at a speed corresponding to the duty ratio of the PWM signal. (Effects of the Invention) According to the present invention, at the document a reading position on the document placement surface,
The document information for two spread pages of a book manuscript placed with the document side facing up can be copied continuously or in a reduced size on one side of a single sheet of transfer paper. , the copying time and copying amount are significantly reduced, and the operability and filing performance are improved.
