2. Description of the Related Art Image reading apparatuses used in image scanners, facsimile machines, and the like include a method of reading an original while conveying the original and a method of fixing the original and moving the reading means to read the original. The method of reading a document while conveying it is easy to downsize due to its structure, but it cannot read special documents such as books, thick paper, and thin paper. on the other hand,
A document of a fixed type that can be read allows a special document to be read, but since the reading area is satisfied, there is a limit to miniaturization. Particularly in a device having both functions, downsizing is a major technical issue.

Therefore, as disclosed in Japanese Unexamined Patent Publication No. 62-275933, there is known one in which a conveyed document is set on a fixed document holder to achieve a compact size. In this conventional technique, the reading means is moved on the same plane to operate both the original fixing mode and the original conveying mode.

Further, in order to convey the conveyed original document to a position separated from the transparent original document table, a pair of conveying rollers for nipping and conveying the original document with a roller pair are used.

[0004]

However, in such a conventional image reading apparatus, the original document feeding means provided on the apparatus box side makes the conveyed original document reading position distant from the transparent original table by that much. However, it cannot be said that the apparatus has been sufficiently downsized because the installation space for the document conveying means cannot be effectively used. Further, since a roller pair type transport roller is used as the transport means, a space corresponding to the space is required, which is disadvantageous for downsizing.

Therefore, the present invention has been made in order to solve such a problem, and an object of the present invention is to provide an image reading apparatus and a facsimile apparatus which can realize miniaturization of the apparatus.

[0006]

Reference numeral 27 denotes a tray (first tray) provided on the upper surface of the fixed document pressing unit 14 for receiving the document discharged from the paper discharge roller pair 26. The tray 27 is arranged at a height that does not hinder the feeding of the original from the original guide 18, and at a position where the original setting on the original guide 18 is not an obstacle, that is, a position where the original guide 18 is not covered. There is.

The idler 28, which is a roller facing the conveying roller 24, is attached to the apparatus box 1 side. Two
Reference numeral 9 denotes a guide for guiding the conveyance-completed document to a tray (second tray) 9 of recording-finished recording paper, and 30 denotes a pair of discharge rollers provided at the exit of the guide 29. Reference numeral 31 denotes a discharge port that linearly discharges the transported original document to the outside, and is formed by a gap opened between the apparatus box body 1 and the fixed document pressing unit 14. Reference numeral 32 denotes a switching plate which is provided at the next stage of the transport roller 24 and which switches the paper discharge direction. The destination of the document to be transported is guided to the tray 27 on the upper surface side, the guide 29 to the internal tray 9, or to the outside. It is switched to any one of the discharge ports 32. This switching plate 3
As shown in FIG. 6, 2 has a tapered guide hole 32a on the side of the conveying roller 24, and upper and lower surfaces thereof serve as guide surfaces 32b and 32c, respectively, which are rotatable about a fulcrum 32d. By manually operating a knob (not shown) attached to the fulcrum 32d, it is possible to perform a switching operation of the paper discharge direction.

FIG. 2 shows the document feeding and reading section.
Will be described in more detail with reference to. Reference numeral 33 denotes a sensor for detecting the presence or absence of a conveyed document, which is a pickup roller 19
The presence of the original is detected by pushing down the original fed out. Reference numeral 34 denotes a pressing plate that presses the original lightly from above, and has a function of stabilizing the original state in the sensor 33 portion and a function of lightly pressing the original against the pickup roller 19. The pickup roller 19 feeds out the document in response to the start signal and sends it to the separating section. The fed document is frictionally separated by the separation roller 20 and the separation pad 21 and becomes a single sheet and is sent to the conveyance roller 22. This document is conveyed by the conveyance roller 22 at a predetermined speed, and while being guided by the flexible sheet 23 and passing through the conveyance document reading position A, image information is read by the image sensor 12. The flexible sheet 23 is made of, for example, a polyester film, and as shown in the partially cut-away perspective view of FIG. 3, adhesives or the like are attached to the hypotenuses of a large number of mounting plates 35 integrally molded on the lower surface side of the tray 27. It is fixed by. In this embodiment, the transport roller 22 is composed of three rollers provided on the shaft 22a at equal intervals, and the portion of the flexible sheet 23 in contact with the rollers 22, 22 has a square hole of a corresponding size. Are formed so that they do not contact each other.

In addition, on the front end side of the flexible sheet 23, a portion corresponding to the conveyed document reading position A of the transparent document table 10 is provided.
A flat plate 36 made of a rigid member such as a metal or a molding material is attached by an adhesive agent or the like, and only this portion is provided with flatness without flexibility. Therefore, the flexible sheet 23 comes into contact with the original document passing therethrough only by the weight of the flat plate 36, imparts the flatness without impeding the transportability of the original document, and prevents the occurrence of waviness and undulation. There is. 37
Are stoppers formed on both ends of the flat plate 36,
By locking the stopper 37 to the locking portion 38 provided integrally on the lower surface side of the tray 27, it is possible to prevent the flexible sheet 23 from moving too downward when the fixed document pressing unit 14 is opened. To prevent.

Reference numeral 39 is a low-friction member made of, for example, polyethylene resin or ethylene tetrafluoride resin, which is adhered in the vicinity of the portion of the fixed original holding plate 15 corresponding to the conveying roller 22. The transport roller 22 is pressed against the fixed document pressing plate 15 via the low friction member 39. Since the pulling force acts on the low friction member 39 and the fixed document pressing plate 15 when the transport roller 22 rotates, the low friction member 39 and the fixed document pressing plate 15 are fixed to the leg portion 17a of the pressure plate 17.

Reference numeral 40 denotes a print band printed on the upper surface of the transparent original platen 15 located below the conveying roller 22. The print band 40 is formed, for example, as shown in FIG. 4 when viewed from the upper surface side of the transparent document table 15. That is, first, the black mark 41 for position detection by the image sensor 12 is printed outside the maximum document width within the reading range of the image sensor 12. Next, band-shaped white printing is performed on the black mark 41 in the width direction, and guide printing is performed on the black mark 41 to instruct the setting position for each document size.

Further, as shown in FIG. 5, a document detection mark 42 is printed on the lower surface side of the flexible sheet 23 corresponding to the transported document reading position A. When the leading edge of the document reaches between the transparent document table 10 and the flexible sheet 23, the document detection mark 42 is blocked by the document and cannot be detected by the image sensor 12, so that the leading end of the document is detected. When the trailing edge of the document passes, the document detection mark 42 is detected, and the trailing edge of the document is detected.

Reference numeral 43 denotes an end detection switch for detecting that the image sensor 12 has reached the left end, and is operated by being pressed by the image sensor 12.

Next, the operation of the facsimile apparatus thus constructed will be described.

The recording of the received image is performed in the recording unit 2. That is, the cassette 3 is synchronized with the reception of the image.
The recording paper is fed out by the paper feed roller 4, the fed recording paper is conveyed and guided by the paper feed roller pair 5 and the guide 6, and the platen 7 is pressed against the thermal head 8 to record the received image. After the recording, the recording paper is discharged and stored in the tray 9. This recording paper is taken out by pulling out the tray 9 toward you.

On the other hand, there are two methods for transmitting an original, that is, fixing the original and conveying the original depending on the type of the original. First, in the case of a special document such as a book, the fixed document holding unit 14 is opened, the transmission page of the book is opened and placed on the transparent document table 10, and the fixed document holding unit 14 is closed. In the case of a normal original, the original is set on the original guide 18 on the fixed original pressing unit 14. In this case, a tray 27 for discharging the paper is provided on the fixed document holding unit 14 in addition to the document guide 18, but since the tray 27 is provided at a position not overlapping the document guide 18, the document guide 18 is provided. It does not interfere with setting the manuscript on page 18.

As described above, when the start button is pressed while the original is set on the transparent original table 10 or the original guide 18, the image sensor 12 detects the black mark 41 printed on the print band 40. Move to. This movement is set so as to move from right to left in FIG. 1 or FIG. 2, but when the image sensor 12 is at the position shown in FIG. The switch 43 is turned on and the direction is changed from left to right. When the image sensor 12 detects the black mark 41, the white image of the print band 40 is read, and shading correction data for correcting the light amount distribution of the light source in the main scanning direction is obtained and stored. After that, the shading correction of the read image is performed based on this correction data.

Next, if the conveyed document detecting sensor 33 is not turned on, it is a fixed document, so the fixed document is read while moving the image sensor 12 to the right. On the other hand, when the conveyed document detecting sensor 33 is on, the conveyed document is set, and therefore the image sensor 12 is moved to the conveyed document reading position A as shown in FIG. The original is separated by the roller 20
Also, the sheets are separated one by one by the separation pad 21 and supplied to the conveyance roller 22. The document is held by the transport roller 22 and the low-friction member 39 attached on the fixed document pressing plate 15 and transported. Here, the transport roller 22 also rotates before the document is loaded, but at this time, the low-friction member 39.
The friction load is small because it is in contact with. Therefore, it is possible to enjoy the advantage of downsizing obtained by using a single roller as the conveying roller instead of the roller pair. Also,
Even when the original is conveyed, the lower surface of the original serves as the low-friction member 39, so that the original can be conveyed smoothly.

The original sent out from the conveying roller 22 is guided by the flexible sheet 23, and is inserted between the transparent original 10 and the flat portion of the flexible sheet to which the flat plate 36 is attached. In this way, by imparting the flatness only to the reading position corresponding portion of the flexible sheet 23, the transportability is improved without deteriorating the reading performance. Further, since the document conveying means such as the conveying roller 22 is mounted on the fixed document pressing unit 14, it is possible to set the fixed document reading position on the lower side of the document conveying means, overlapping with the document conveying means. That is, here, up to the print band 40 is used for reading the fixed document. Therefore, a useless space for the document conveying means is unnecessary, and as a result, the apparatus can be downsized.

The image sensor 12 detects the document detection mark 42 at the conveyed document reading position A, and detects the leading end of the document by blocking the mark 42 with the conveyed document. When the leading edge of the document is detected, the transport of the document is temporarily stopped and the reading operation is started, and thereafter, the transport and the reading operation of the document are alternately performed. When the document detection mark 42 is detected by the passage of the trailing edge of the document, and the trailing edge of the document is detected, the reading operation ends and the document is ejected. As described above, since the image sensor 12 can detect the leading edge and trailing edge of a document, the document leading edge and trailing edge detection sensors are not required on the document transportation path, and the transportation of the document is not hindered. ,
The device can be constructed inexpensively. In order to detect the leading edge of the document by the image sensor 12, the image sensor 1
2 needs to move to the reading position A before the document, but the distance until the image sensor 12 reaches the reading position A is much larger than the distance until the document reaches the reading position A. Because it is short, there is no problem.

For the original sent by the conveying roller 24 and the idler 28 after completion of reading, the discharge destination is selected by the switching plate 32. The switching plate 32 is set to one of the states shown in FIGS. 6 to 8 by the operator operating a knob (not shown). FIG. 6 shows a set state in which the sent document P is guided by the guide hole 32 a of the switching plate 32 and directly discharged from the discharge port 31. Further, in FIG. 7, the document P is guided by the lower guide surface 32c of the switching plate 32 and guided to the tray 9 inside the apparatus 29.
The setting state is shown in FIG. And in FIG.
The setting state is shown in which the document P is guided by the upper guide surface 32b of the switching plate 32 and discharged to the guide 25 to the tray 27 at the upper part of the apparatus. In this way, by operating the switching plate 32 according to the operator's intention to select the storage area for the discharged original, the discharged original can be stored within the area occupied by the apparatus.

As shown in FIG. 6, when the document P is directly discharged to the outside from the discharge port 31, the operator directly receives it by hand or attaches a detachable stacker to receive it. This is convenient when reading a large number of thick originals. That is, normally, a thick original is read one by one with the original fixed, but if the paper is linearly ejected, it can be conveyed and read.

Further, as shown in FIG. 7, the document P is guided by the guide 29.
To the tray 9 inside the apparatus by the discharge roller pair 30.
In the case of being ejected, there is an advantage that the ejected document can be stored within the area occupied by the apparatus and the ejected document does not get in the way. Further, since the original is discharged to the same tray 9 as the recording paper, one tray can be saved, which is advantageous for downsizing.

Then, as shown in FIG.
When the sheet is sent to the sheet No. 5 and is discharged to the upper portion of the apparatus, that is, the tray 27 on the fixed document pressing unit 14 by the discharge roller pair 26, there is an advantage that it can be stored within the area occupied by the apparatus and the document can be easily handled. . The tray 27 is
The tray is not formed to have a sufficient size due to the restriction that it does not disturb the document setting on the document guide 18 and the size reduction. Therefore, depending on the size of the original document, the leading edge side may protrude toward the original document guide 18 side, but the trailing edge side of the original document may remain on the tray 27, so that the discharged original document may be ejected.
There is no problem of being set again and transported again.

In the above embodiment, after the start button is turned on, the image sensor 12 moves to the print band 40 to perform the processing for obtaining the shading correction data. However, as shown in the flowchart of FIG. When the power switch is turned on, the movement of the image sensor 12 and the shading correction data calculation process may be performed as a preparatory operation.

That is, as shown in FIG. 9, when the power switch is turned on, the reading operation of the image sensor 12 is started (process 101). In this reading operation, it is determined whether the black mark 41 attached to the print band 40 is detected (decision 102). If the black mark 41 is not detected, the image sensor 12 is moved to the left (process 10).
3) It is determined whether the black mark 41 is detected (decision 104). If the black mark 41 is not detected, it is determined whether the end detection switch 43 is turned on (decision 10).
5). If the end detection switch 43 is in the off state, the process returns to the judgment 104, and the judgment 104 and the judgment 105 are made until the black mark 41 is detected or the end detection switch 43 is turned on.
Repeat. Here, when the end detection switch 43 is turned on, the image sensor 12 is switched to the rightward movement (process 106). Then, the above loop is repeated until the black mark 41 is detected. Black mark 4 at decision 104
When 1 is detected, the process proceeds to step 107 and the movement of the image sensor 12 is stopped. Then, by reading the white image of the print band 40, the above-described shading correction data is obtained and stored (process 108). This process 108
When is finished, the reading operation of the image sensor 12 is stopped (process 109).

Next, it is determined whether or not the start button is turned on (decision 110), and the process waits until the start button is turned on. When the start button is turned on, it is determined whether the conveyed document detection switch 33 is turned on (determination 111),
If the switch 33 is not on, it means that the conveyed original is not set, so the image sensor 12 is moved to the right and the fixed original placed on the transparent original table 10 is read (process 112).

On the other hand, if the conveyed document detecting switch 33 is turned on, it means that the conveyed document has been set. Therefore, the document is conveyed and the image sensor 12 is moved leftward to the conveyed document reading position A. Allow (Process 11
3). Next, it is determined whether or not the leading edge of the document is detected (decision 114), and if the leading edge of the document is detected as described above, the reading operation of the image sensor 12 is performed (Process 1).
15). After the reading operation of this process 115, it is determined whether the trailing edge of the document is detected (decision 116). Judgment 1 above
When the leading edge of the original cannot be detected in 14 or when the trailing edge of the original cannot be detected in determination 116, an error display of the original jam is performed assuming that a paper jam has occurred (Processing 11).
7). When the trailing edge of the document is detected in the determination 116, the document is discharged and the process ends (process 118).

In the operation of the image sensor 12 of the above-described embodiment, the portion where the position is not detected by the mark or the switch is controlled by counting the pulse number of the stepping motor constituting the drive system.

Further, in the above embodiment, the document conveying process to the reading position A and the image sensor moving process are performed at the same time, but the image sensor moving process may be performed before the document conveying process, In this case, the leading edge of the document can be detected more reliably.

Further, a position detecting mark 43 similar to the black mark 41 attached to the print band 40 shown in FIG. 4 is provided at a portion of the flexible sheet 23 corresponding to the conveyed document reading position A in FIG.
It may be provided as indicated by 0. By doing so, the termination detection switch 43 becomes unnecessary.

According to the first aspect of the present invention, since the feeding original reading position is set at one end of the transparent original table and the original feeding means is attached to the fixed original pressing unit,
The fixed document reading position can be set to overlap with the document conveying means. Therefore, no unnecessary space is required for the document conveying means, and as a result, the apparatus can be downsized.

Further, according to the inventions of claims 2 to 6, the following effects can be obtained in addition to the effects of claim 1. That is, according to the second aspect of the present invention, the document conveyed by the document conveying means is selectively discharged by the switching means to the upper portion of the apparatus, the inside of the apparatus, or the outside of the apparatus. Therefore, by operating the switching means according to the operator's intention to select the storage area for the discharged original, the discharged original can be stored within the area occupied by the main body, and the size can be reduced. Further, the linear paper discharge to the outside of the apparatus is convenient for reading a large amount of thick originals. That is, normally
This is because the thick original can be read one by one with the original fixed, but it can be conveyed and read as long as it is a linear paper discharge.

According to the third aspect of the present invention, since the original document which has been conveyed can be stored in the tray on the upper surface of the fixed original document holding unit, that is, in the area occupied by the main body, and does not interfere with the setting of the original document on the conveyed original document loading table, Miniaturization can be achieved without disturbing the set.

According to the fourth aspect of the present invention, the fixed document holding plate is covered with the low friction member, and the conveying roller is pressed against the transparent document table side from above. Therefore, since the transport roller does not directly contact the transparent document table or the fixed document pressing plate but contacts the low friction member, the friction load applied to the roller when the roller is rotated can be greatly reduced without the document intervening. For this reason,
It is possible to enjoy the advantage of downsizing obtained by using a single roller as the conveying roller instead of the roller pair.

According to the invention of claim 5, the flexibility of the sheet provided on the document transport path ensures continuity of document transport, and the attached flat plate allows flexibility at the reading position. The sheet is wavy in the width direction of the original,
It is possible to prevent the generation of undulations. Further, since the pressing force is not applied, the transportability is not hindered.
