Description

[Detailed explanation of the idea]

0001

[Industrial application field]

In this invention, a transparent film is stacked on a mount with the edges joined, and the document is placed between the two. Regarding document carrier sheets configured to be able to sandwich If the original is larger than the size that can be copied, divide the original into multiple parts and make continuous copies. Concerning a document carrier sheet suitable for processing.

0002

[Conventional technology]

Conventionally, copying machines generally have a contact glass on a copying machine main body 301, as shown in FIG. Set the original B on the stand 302, fix the original B with the pressure bonding plate 600, and start. A series of copying processes is executed by operating a switch 400. has been done. In this case, the size A that can be processed for copying is preset depending on the model. , the contact glass 302 has a shape corresponding to this copying processable size A. Ru. By the way, when performing copy processing on originals B of various sizes, originals B There is no problem if it is smaller than the processable size A, but if it is larger than the copy processable size A. If the image be lost.

0003 At this time, for example, the document B is approximately twice the size of A3, which can be copied. For the A2 document, first, as shown in FIG. 7(a), the first half B1 of the document B is Set the position on the contact glass 302, and hold it in place while fixing it with the crimp plate 600. Operate the start switch 400 to copy the first half image G1 onto the copy paper C1, and then copy the first half image G1 onto the copy paper C1. Then, as shown in the same figure (b), position and set the rear half B2 of document B in the same way. The second half of the image G2 will be copied onto the copy paper C2, and the copying process will be very difficult. It becomes complicated.

0004 In normal copying machines, white areas (erasures) are placed on the leading and trailing edges of copy paper C1 and C2. ) is created, so there should be no overlap between the first half B1 and the second half B2 of manuscript B. As shown in FIG. 8(a), an uncopied portion is generated between the front and rear images G1 and G2. . Furthermore, if the document B has creases or is attached around the contact glass 302, If there is a protrusion in the position, the document B will move when the crimp plate 600 is closed, and this Therefore, as shown in FIG. 8(b), the front and rear images G1 and G2 are bent, resulting in two copies being - Fixed various problems such as not being able to paste sheets C1 and C2 straight together. arise.

[0005] From this, when the original B is larger than the size A that can be processed for copying, In order to make the work easier and faster, and to reduce copy errors, Measures are needed. One way to do this is to use a carrier sheet to simulate manuscript B. It is designed to look like computer-formed paper, and is suitable for automatic document feeders in copiers. automatically divides the document B into each size A that can be copied and processes the copies. It is conceivable to manage the

[0006] Conventionally, carrier sheets for originals, etc., were not used in sheet-through copiers. In order to protect thin documents and stabilize the transport, cover the document with a transparent film. There are some that are sandwiched between a mount and a mount. Also, Utility Model No. 61-22032 In the prior art published in the publication, the connection between copy paper and drum when transporting thin copy paper is In order to prevent the occurrence of wrinkles due to pressure bonding, a thick sheet is attached to the tip of this sheet. A copy paper locking means is provided at the edge, and at least one cut is made in the conveyance direction of the sheet. What is provided above is disclosed.

[0007]

[Problem that the idea aims to solve]

However, the carrier sheet of the above-mentioned prior art merely protects the original. It only has the function of preventing wrinkles and wrinkles, so it is not suitable for automatic document feeders. The problem was that it was impossible to respond.

[0008] In addition, when dividing a document into sizes that can be copied and making continuous copies, it is possible to The problem with using a carrier sheet like that used in line technology is that copying work becomes more complicated. There was a point.

[0009] This invention was made in view of the above, and it is possible to by making it into a pseudo computer form paper and making it possible to adapt it to an automatic document feeder. To improve workability, copy accuracy, etc. when dividing originals into continuous copy processing. purpose.

0010

[Means to solve the problem]

In order to achieve the above purpose, the present invention combines the edges of a transparent film with a mount. Document carrier sheet configured to allow documents to be stacked on top of each other and sandwiched between the two. The mount and the transparent film are formed to be longer than a copyable size, and A protrusion is formed on the side of the mount, and the protrusion automatically supports computer form paper. A document carrier with holes at regular intervals that can be transported by a document feeder. It provides sheets.

[0011] In addition, the original has a mark provided at a predetermined position on the joining side of the mount to prevent image chipping. It provides a manuscript carrier sheet.

0012

[Effect]

Based on the above configuration, when copying a document larger than the size that can be copied. , sandwich the original between a backing paper and a transparent film, and transfer it to the automatic document feeder. Set it up and perform copying work in the same way as for copying computer form paper. So As a result, the automatic document feeder recognizes the paper as computer form paper due to the punched holes. automatically divides the original, transports and exposes the document, overlaps some parts, and prints them continuously. Multiple sheets of copy paper can be obtained easily and quickly, and these copy papers can be pasted together. At the same time, it becomes possible to properly produce a sheet of copy paper that matches the original.

[0013]

【Example】

Hereinafter, embodiments of the present invention will be described based on the drawings. In Figure 1, the document carrier The sheet 100 is approximately the same width as the size A that can be processed for copying, and a size longer than the length. It has a transparent film 102 with a width of A transparent film 102 is bonded to 101 by an adhesive portion 103 at the tip and overlapped. , for example, insert an A2 original B, which is larger than the A3 A3 size that can be copied, between the two. It is now possible to A protrusion is formed on one side of the transparent film 102 of the mount 101. 104 is formed, and this protrusion 104 is provided with a punch hole 105.

[0014] Figure 3 shows an explanation of an automatic document feeder that supports computer form paper. I will clarify. The automatic document feeder 300 is connected to a contact glass on the top of the copying machine main body 301. 302, a document separation/feed section 310, a document transport section 330, and a document discharge section 340. It is constructed by sequentially arranging.

[0015] The document separation/feed unit 310 is used for loading and setting documents with the document side facing down. A table 311, an entrance claw 312 that aligns the leading edge of the document and regulates paper feeding, A calling roller 313, a separation roller 314, and a separation blade 31 that transport in a predetermined direction. 5. A pair of pull-out rollers 316, a document separator that detects when a document is set. registration sensor 317, a registration sensor that detects when the original has reached the registration position. 318. In addition, in response to the copying process of computer form paper D, C It has an F paper feed port 320, and a computer screen is installed at the CF paper feed port 320. punch hole detection sensors 321, 322, which detect punch holes provided in the paper D; CF paper detection sensor 323 that detects computer form paper D; ID plates 324 are provided respectively.

[0016] The document transport unit 330 is large enough to cover the entire surface of the contact glass 302 and is driven. The document conveying belt 333 passed between the roller 331 and the driven roller 332, A plurality of pressure rollers press the document conveyance belt 333 onto the contact glass 302. 334.

[0017] The original discharge unit 340 is conveyed and set onto the contact glass 302 and exposed. The intermediate conveyance roller 341 that takes over when the processed original is ejected, and the ejection history of the original Switching to selectively switch the road straight or to the upper turn guide 342 A claw 343, a paper ejection roller 344 provided in a straight ejection path to eject the paper, and a turn A reversing roller 345 and a turn roller are provided in the ejection path of the guide 342 and eject the paper. 346. In addition, a reversal registration sensor 3 is provided on the path of the turn guide 342. 47, a reversing entrance sensor 348 is provided, and a paper ejection sensor is provided on the path of the paper ejection roller 344. A charger 349 and a static eliminating brush 350 are provided, respectively.

[0018] On the other hand, computer form paper D has punch holes on one side, as shown in Figure 4. E are continuously provided at a constant pitch. Therefore, the document separation and feeding section 31 The CF paper detection sensor 323 of No. 0 is arranged on the conveyance path of the computer form paper D. punch hole detection sensor 321, 322 is placed in the path of the punched holes E to count the number of punched holes E, and Detects the feed amount of the computer form paper D and controls the stop at the reference position. It is configured so that it can be used.

[0019] As a result, when copying computer-form paper D, the computer Place the CF paper D on the document table 311, and place the first page on the CF paper. Pass the paper through the paper feed port 320 and set the leading end at the reference position on the contact glass 302. When the start switch 400 is turned on, first one page of computer form paper D is turned on. The image is exposed and scanned to perform copy processing, and after this exposure scan, the CF paper detection sensor 32 3 and punch hole detection sensors 321 and 322, the document transport belt 333 is driven. The first page is ejected, and the second page is transported and set at the reference position. The document is exposed and scanned in the same way by the automatic document feeder 300. Copying work is performed continuously while the computer form paper D is automatically transported. .

[0020] Therefore, in the document carrier sheet 100 described above, punch holes in the protrusion 104 are 105 is similar to the above computer form paper D, for example, about 4φ and 1 They are arranged in a straight line at a constant pitch of /2 inch. This allows punch hole detection. The sensors 321 and 322 similarly detect the punched hole 105, and the automatic document feeder 3 00 recognizes the document carrier sheet 100 as computer form paper D. , it is possible to drive and control the document conveyance belt 333.

[0021] Here, for example, the width of an A3 document is 297 mm, but the automatic document feeder 30 The feed amount by 0 is set to 279 mm, so the document carrier sheet 1 For example, the first half and the second half of an A2 document sandwiched between 00 and 00 are copied by 18 mm. The uncopied parts of the rear end of the first half and the tip of the second half will be erased. This has the advantage of not being able to do this, but on the other hand, images may be missing by the amount of overlap at the leading or trailing edge of an A2 document. Let's go. Therefore, as a measure to prevent this image loss, a document carrier is installed as shown in Figure 2. Mark 2 for aligning the original at a position 9 mm from the tip of the mount 101 of the sheet 100 00 is provided, and image defects are detected at 9 mm at the leading edge of the first half of the document and at 9 mm at the rear end of the second half. Divide into. Generally, there is no image within a 10mm area between the leading edge and trailing edge of an A2 document. Therefore, it is possible to practically prevent image defects by using the above-mentioned measures to sort out image defects. become.

[0022] Next, a document B larger than the size A that can be copied is placed on the document carrier sheet 100. The operation when copying is performed using this will be explained with reference to FIG. First, place the leading edge of the original Align the image G with the mark 200 on the document carrier sheet 100 and face the transparent film side. Then, the document B is sandwiched between the mount 101 and the transparent film 102. The manuscript carrier As shown in FIG. 5(a), the document sheet 100 is As in the case of CF paper D, pass it through the CF paper feed port 320, and 02 to its reference position facing the contact glass 302, and turn on the start switch. switch 400 is turned on. As a result, the front of the document B inside the document carrier sheet 100 is The half B1 is exposed and scanned through the transparent film 102, and the first half is printed on the copy paper C1. Image G1 is subjected to copy processing. At this time, the CF paper detection sensor of the automatic document feeder 300 The sensor 323 detects the document carrier sheet 100, and the punch hole detection sensors 321, 3 22 detects the punch hole 105 and recognizes it as computer form paper D. Ru.

[0023] Therefore, the automatic document conveyance device 300 drives the document conveyance belt 333 to The document carrier sheet 100 is automatically conveyed, and at this time, the document B is transferred to the document carrier sheet 100. Protected from scratches by sheet 100, and stabilized by eliminating creases, etc. transported. The second half B2 of the document B is placed on the contact glass 3 as shown in FIG. 5(b). Set the second half image G on the other copy paper C2 continuously in the same way. 2 is copied, and in this case, the CF paper detection sensor 323 detects the end of the document. By doing so, the document carrier sheet 100 is immediately ejected by the document ejecting section 340. Finish copying work.

[0024] In this way, the images G1 and G2 that have been copied onto the two copy sheets C1 and C2 are as follows: It is straight and continuous, and a part of the center is overlapped to prevent image chipping. It becomes a duplicate. Therefore, it is necessary to cut the overlapping parts of the two sheets of copy paper C1 and C2. By doing so, the images G1 and G2 are pasted straight together with the copy sheets C1 and C2. In this way, it is possible to properly make an exact copy of original B. Ru.

[0025]

[Effect of the idea]

As explained above, according to the present invention, the document carrier sheet is Documents that are printed on format paper and are larger than the size that can be copied are stored in the document scanner. Using the rear seat and automatic document feeder compatible with computer form paper, The original is automatically divided and continuous copy processing is performed, making the copying process much easier. First, it becomes faster. The images on the copy paper are continuous with some overlap, so they are not true. You can create a copy that is exactly the same as the original by directly pasting it together, which greatly reduces copy mistakes. reduce

[0026] In addition, since the original is transported on the original carrier sheet, the original is reliably protected and transported. It can improve image stability and accuracy. The document carrier sheet has a simple structure. It is simple, easy to operate, and highly practical. Furthermore, on the manuscript carrier sheet By providing a mark for document alignment, it is possible to accurately prevent image loss.
