  FIG. 1 is a schematic view of a sheet conveying apparatus A according to the first embodiment of the present invention.

<Device configuration>
The sheet conveying apparatus A is an apparatus that conveys one or a plurality of conveying media S stacked on the mounting table 1 one by one in the apparatus along a route RT, reads the image, and discharges the image onto the discharge tray 2. The reading medium S to be read is, for example, a sheet of OA paper, a check, a check, a card or the like, and may be a thick sheet or a thin sheet. Examples of the cards include an insurance card, a driver's license, and a credit card. The transport medium S also includes a booklet such as a passport. When targeting a booklet, a holder 100 described later can be used. By storing the booklet in a spread state in the holder 100 and placing it on the mounting table 1, the booklet is transported together with the holder 100 and the image can be read.

  A first transport unit 10 is provided as a feeding mechanism that feeds the transport medium S along the route RT. In the case of this embodiment, the first transport unit 10 includes a feed roller 11 and a separation roller 12 disposed to face the feed roller 11, and sequentially transports the transport medium S on the mounting table 1 one by one in the transport direction D1. Transport. A driving force is transmitted to the feed roller 11 from the driving unit 3 such as a motor through the transmission unit 5 and is rotationally driven in the direction of the arrow in the drawing (the forward direction in which the transport medium S is transported along the path RT). The transmission unit 5 is, for example, an electromagnetic clutch, and interrupts the driving force from the driving unit 3 to the feed roller 11.

  For example, in this embodiment, the transmission unit 5 that connects the drive unit 3 and the feed roller 11 is in a state in which the driving force is transmitted in a normal state, and interrupts the driving force when the transport medium S is reversely fed. When the transmission of the driving force is interrupted by the transmission unit 5, the feed roller 11 is in a freely rotatable state. In addition, such a transmission part 5 does not need to be provided when driving the feed roller 11 only in one direction.

  The separation roller 12 disposed to face the feed roller 11 is a roller for separating the transport medium S one by one, and is in pressure contact with the feed roller 11 with a constant pressure. In order to secure this pressure contact state, the separation roller 12 is provided so as to be swingable and is urged to the feed roller 11. The separation roller 12 is driven to rotate in the direction indicated by the solid line arrow (the direction opposite to the forward direction of the feed roller 11) when the driving force is transmitted from the driving unit 3 via the torque limiter 12a.

  Since the driving force transmission is restricted by the torque limiter 12a, the separation roller 12 rotates in a direction (indicated by a broken arrow) along with the feed roller 11 when contacting the feed roller 11. As a result, when a plurality of transport media S are transported to the pressure contact portion between the feed roller 11 and the separation roller 12, two or more transport media S are blocked so that they are not transported downstream except one. .

  In the present embodiment, the separation roller 12 and the feed roller 11 constitute a separation mechanism. However, such a separation mechanism is not necessarily provided, and the conveyance medium S is sequentially fed to the path RT one by one. Any feeding mechanism may be used. In the case where a separation mechanism is provided, instead of the configuration of the separation roller 121, a separation pad that applies a frictional force to the transport medium S is brought into pressure contact with the feed roller 11 so as to have the same separation work. May be.

  The second transport unit 20 as a transport mechanism on the downstream side in the transport direction D1 of the first transport unit 10 includes a drive roller 21 and a driven roller 22 driven by the drive roller 21 and is transported from the first transport unit 10. The transported medium S is transported downstream. Driving force is transmitted to the driving roller 21 from the driving unit 4 such as a motor, and the driving roller 21 is rotationally driven in the direction of the arrow in the figure. The driven roller 22 is brought into pressure contact with the driving roller 21 at a constant pressure, and rotates with the driving roller 21. The driven roller 22 may be configured to be biased against the driving roller 21 by a biasing unit (not shown) such as a spring.

The third transport unit 30 on the downstream side in the transport direction D1 with respect to the second transport unit 30 includes a drive roller 31 and a driven roller 32 that judos the drive roller 31 and is transported from the second transport unit 20. The transport medium S is transported from the discharge port between the driving roller 31 and the driven roller 32 to the discharge tray 2. That is, the third transport unit 30 functions as a discharge mechanism. Driving force is transmitted to the driving roller 31 from the driving unit 4 such as a motor, and the driving roller 31 is rotationally driven in the direction of the arrow in the figure. The driven roller 32 is brought into pressure contact with the driving roller 31 at a constant pressure, and is driven by the driving roller 31. The driven roller 32 may be configured to be biased against the driving roller 31 by a biasing unit (not shown) such as a spring.

  The sheet discharge tray unit 2 is pivotally supported via a first hinge 208a provided below the sheet conveying apparatus A so as to be rotatable with respect to the sheet conveying apparatus A. The first paper discharge tray 200a on the first hinge 208a side and the first paper discharge tray 200b connected to the front end thereof are configured, and the second paper discharge tray 200b is the front end of the first paper discharge tray 200a. The second hinge 208b provided on the shaft is pivotally supported about a fulcrum. FIG. 1 shows a tray unfolded state at a position where the paper discharge tray unit 2 receives the sheets discharged from the sheet conveying apparatus A, that is, a position where the discharged sheets can be stacked (first position).

  Here, in the sheet conveying apparatus A according to the present embodiment, the image reading unit 70 disposed between the second conveying unit 20 and the third conveying unit 30 reads an image. The three transport unit 30 transports the transport medium S at a constant speed. By always setting the transport speed to be equal to or higher than the transport speed of the first transport unit 10, it is possible to reliably avoid a situation in which the subsequent transport medium S catches up with the preceding transport medium S. For example, in this embodiment, speed control is performed so that the transport speed of the transport medium S by the second transport section 20 and the third transport section 30 is faster than the transport speed of the transport medium S by the first transport section 10. did.

  Even when the transport speed of the transport medium S by the second transport section 20 and the third transport section 30 and the transport speed of the transport medium S by the first transport section 10 are the same, the drive section 3 is controlled. It is also possible to form a minimum interval between the preceding transport medium S and the subsequent transport medium S by intermittently shifting the feeding start timing of the subsequent transport medium S.

  When the double feed detection sensor 40 disposed between the first transport unit 10 and the second transport unit 20 is in contact with transport media S such as paper due to static electricity or the like, and passes through the first transport unit 10 ( In other words, this is an example of a detection sensor (a sensor for detecting the behavior and state of the sheet) for detecting this in the case of a double feed state in which the sheets are conveyed in an overlapping manner. Various sensors can be used as the double feed detection sensor 40, but in the case of the present embodiment, it is an ultrasonic sensor, and includes an ultrasonic transmission unit 41 and a reception unit 42, and is a conveyance medium such as paper. Double feed is detected based on the principle that the attenuation amount of the ultrasonic wave passing through the transport medium S is different between the case where S is transported one by one and the case where S is transported one by one.

  The medium detection sensor 50 disposed on the downstream side in the transport direction D1 with respect to the double feed detection sensor 40 is upstream of the second transport unit 20 and upstream of the first transport unit 10. Detection sensor (sensor for detecting the behavior and state of the sheet), and the position of the transport medium S transported by the first transport unit 10, specifically, the transport medium S at the detection position of the medium detection sensor 50. It is detected whether or not the end of has reached or passed. As the medium detection sensor 50, various sensors can be used. In the case of this embodiment, the medium detection sensor 50 is an optical sensor, and includes a light emitting unit 51 and a light receiving unit 52, and receives light when the transport medium S reaches or passes therethrough. The transport medium S is detected based on the principle that the intensity (the amount of received light) changes.

  In the case of this embodiment, when the leading edge of the transport medium S is detected by the medium detection sensor 50, the above medium is used so that the transport medium S reaches a position where the double feed detection sensor 40 can detect double feed. The detection sensor 50 is provided on the downstream side in the vicinity of the double feed detection sensor 40. The medium detection sensor 50 is not limited to the optical sensor described above. For example, a sensor (image sensor or the like) that can detect the end of the transport medium S may be used, or a lever-type sensor that protrudes into the path RT. It may be a sensor.

  The medium detection sensor 60 different from the medium detection sensor 50 is an example of a downstream detection sensor disposed upstream of the image reading unit 70 and downstream of the second transport unit 20. The position of the transport medium S transported by the unit 20 is detected. Various media detection sensors 60 can be used. In the case of the present embodiment, the medium detection sensor 60 is an optical sensor similar to the medium detection sensor 50, and includes a light emitting unit 61 and a light receiving unit 62. The transport medium S is detected based on the principle that the received light intensity (received light amount) changes due to arrival or passage. In the present embodiment, the medium detection sensors 50 and 60 are disposed on the upstream side and the downstream side in the transport direction D1 of the second transport unit 20, respectively, but only one of them may be used.

  The image reading unit 70 on the downstream side of the medium detection sensor 60 is, for example, optically scanned, converted into an electric signal and read as image data, and internally includes a light source such as an LED, an image sensor, and a lens array. Etc. In the present embodiment, one image reading unit 70 is disposed on each side of the path RT, and reads the front and back surfaces of the transport medium S. However, only one side of the route RT may be arranged to read only one side of the transport medium S. Further, in the present embodiment, the image reading unit 70 is configured to be opposed to both sides of the route RT. However, for example, the image reading unit 70 may be arranged with an interval in the direction of the route RT.

  The control unit 8 will be described with reference to FIG. FIG. 2 is a block diagram of the control unit 8 of the sheet conveying apparatus A.

  The control unit 8 includes a CPU 81, a storage unit 82, an operation unit 83, a communication unit 84, and an interface unit 85. The CPU 81 controls the entire sheet conveying apparatus A by executing a program stored in the storage unit 82. The storage unit 82 includes, for example, a RAM, a ROM and the like. The operation unit 83 includes, for example, a switch, a touch panel, and the like, and accepts an operation from the operator.

  The communication unit 84 is an interface that performs information communication with an external device. When a PC (personal computer) is assumed as the external device, examples of the communication unit 84 include a USB interface and a SCSI interface. In addition to such a wired communication interface, the communication unit 84 may be a wireless communication interface, and may include both wired communication and wireless communication interfaces.

  The interface unit 85 is an I / O interface that inputs and outputs data with the actuator 86 and the sensor 87. The actuator 86 includes the drive unit 3, the drive unit 4, the transmission unit 5, and the like. The sensor 87 includes a double feed detection sensor 40, medium detection sensors 50 and 60, an image reading unit 70, and the like.

  A basic operation of the sheet conveying apparatus A will be described. For example, when the control unit 8 receives an image reading start instruction from an external personal computer to which the sheet conveying apparatus A is connected, the control unit 8 starts driving the first to third conveying units 10 to 30. The transport medium S loaded on the mounting table 1 is transported one by one from the transport medium S positioned at the bottom.

  During the conveyance, the conveyance medium S is determined by the double-feed detection sensor 40 to determine whether or not there is a double-feed, and if it is determined that there is no double-feed, the conveyance is continued. If it is determined that there is a double feed, the transport is stopped or the capture of the subsequent transport medium S by the first transport unit 10 is stopped, and the transport medium S in the double feed state is discharged as it is. It may be.

  The control unit 8 starts reading an image of the transport medium S transported by the second transport unit 20 by the image reading units 70 and 70 at a timing based on the detection result of the medium detection sensor 60, and reads the read image. Temporarily memorize and send to external PC. The transport medium S from which the image has been read is discharged to the discharge tray 2 by the third transport unit 30, and the image reading process for the transport medium S is completed.

  FIG. 12 is a cross-sectional view of a state in which the paper discharge stopper 202 incorporated in the second paper discharge tray 200b according to the first embodiment of the present invention is housed.

  As shown in FIGS. 6 and 7, the paper discharge stopper 202 is incorporated in the paper discharge stopper base 203 and is rotatably attached with the rotation shaft 204 of the paper discharge stopper 202 as a fulcrum. When the paper discharge stopper 202 is used, the paper discharge stopper 202 is used in an upright state as shown in FIG. 11, and when the paper discharge stopper 202 is not used, the paper discharge stopper 202 is used as shown in FIG. It is used in a state where it is stored in the same plane as the paper discharge stopper table 203. The paper discharge stopper 202 is provided with a click portion 207 in the vicinity of the rotation shaft 204, and the click portion 207 can be kept standing by getting over the convex portion of the paper discharge stopper base 203 (not shown).

  The paper discharge stopper 202 incorporated in the second paper discharge tray 200b is configured to rotate and store in the sheet discharge direction X as shown in FIG. 7, and the paper discharge stopper incorporated in the first paper discharge tray 200a. The stopper 202 is configured to rotate and store in a direction opposite to the sheet discharge direction X as shown in FIG. As the rotation direction of the sheet discharge stopper 202, the sheet discharge direction X and the reverse direction can be selected depending on the space of the sheet discharge tray, the position of the stopper, and the like.

  As shown in FIGS. 9 and 10, the paper discharge stopper 202 incorporated in the first paper discharge tray 200 a is formed when the click portion 207 gets over the convex portion provided on the paper discharge stopper base 203. And the first paper discharge tray 200a when the paper discharge opening of the apparatus main body comes into contact with the first paper discharge tray 200a so that the angle V becomes an acute angle, and further, it can be rotated to the apparatus main body side (that is, the sheet discharge opening side). A play is provided with the rotation shaft 204 as the center of rotation. For this reason, as shown in FIG. 10, the discharge tray unit 2 is moved from the position (first position) where the sheet discharge tray unit 2 receives the sheet discharged from the sheet conveying apparatus A (the first position). When tilted in the direction of tilting toward the apparatus main body, when the paper discharge stopper 202 gets over the click portion 207 and the paper discharge outlet of the apparatus main body of the paper discharge stopper 202 comes into contact with the first paper discharge tray 200a. When the angle V becomes an acute angle, the sheet discharge stopper 202 falls to the sheet discharge tray 2 side as it is, and the sheet discharge tray unit 2 is closed at a position (second position) that covers the exterior of the apparatus main body, the sheet discharge stopper 202 moves the sheet. The device A comes into contact with the external surface of the apparatus A, falls as it is toward the first paper discharge tray 200a, and is accommodated in the paper discharge stopper table 203. Therefore, even when the paper discharge tray unit 2 is closed to the apparatus main body without storing the paper discharge stopper 202, the paper discharge stopper 202 does not collide with the external surface of the sheet conveying apparatus A. Can be stored smoothly. In addition, it is preferable to attach an R shape or a C surface cut as shown in FIG. 9 so that the front end of the paper discharge stopper 202 can be easily rotated in the closing direction when contacting the external surface of the sheet conveying apparatus A. However, the present invention is of course not limited to this, and the R shape may not be provided. In this embodiment, the discharge stopper unit 203 is accommodated by contacting the exterior of the apparatus main body while tilting the discharge stopper 202 as the discharge tray unit 2 rotates. The invention is of course not limited to this, and the discharge stopper 202 may be completely tilted to the tray surface by rotating the discharge tray unit 2.

The sheet discharge stopper 202 includes a pair of left and right sheet discharge contact portions 205 that receive the sheet S that has been discharged and arrives from the sheet discharge direction X. The paper discharge contact portion 205 is one step higher than the paper discharge stopper surface (surface other than the paper discharge contact portion) 206, and is disposed at a position where the discharged paper contacts the earliest. Further, each of the raised paper discharge contact portions 205 is a linear portion extending toward the paper discharge stopper table 203 on the paper discharge stopper surface 206, and can receive the leading edge of the sheet S over a wide range. It has become. That is, regardless of the height at which the discharged sheet S collides with the paper discharge stopper 202, the paper discharge abutment portion 205 extends up and down with the paper discharge contact portion 205 as a linear portion. It is easy to absorb.

After the leading edge of the discharged sheet S comes into contact with the discharge contact portion 205 and returns to the upstream side of the conveyance, when the subsequently discharged sheet S contacts the discharge stopper 202, the discharge contact Since the sheet S that has been discharged first does not remain in the vicinity of the contact portion 205 and the discharged sheet S can be brought into contact with the discharge contact portion 205, the sheet S is placed on the discharge tray 200. Even when a plurality of sheets are loaded, collision energy can always be absorbed.

With the above-described configuration, when the leading edge of the discharged sheet S passes through the discharge tray unit 2 and collides with the discharge contact portion 205 in the discharge stopper 202, the discharge shown in FIG. The lower end portion 205a of the paper contact portion 205 can be brought into contact with the sheet S, and the load carrying portion 205a is displaced in the sheet discharge direction X, so that the collision energy can be absorbed and the collision sound can be reduced. Can do. In addition, the paper discharge stopper 202 can be rotated, and when the paper discharge stopper is not used, it is arranged so that it is flush with the paper discharge stopper table 203. Even when the sheet is conveyed, the sheet S can be conveyed without being jammed or damaged.

  In addition, according to the above-described configuration, the attachment position of the first hinge 208a can be provided at the lowermost end portion of the apparatus main body, so that it is possible to earn a distance that the discharged sheet contacts the first discharge tray 200a. , The alignment of discharged sheets can be improved.

  FIG. 15 is a cross-sectional view of the paper discharge stopper 202 according to the second embodiment of the present invention.

  The paper discharge stopper 202 includes a paper discharge contact portion 205 that receives the discharged sheet S. The paper discharge contact portion 205 is one step higher than the paper discharge stopper surface (surface other than the paper discharge contact portion) 206, and is disposed at the position where the discharged paper contacts the earliest. The paper discharge contact portion 205 is provided so as to be displaceable in the sheet discharge direction X by being elastically deformed, and absorbs the collision energy when the leading edge of the discharged sheet S collides. In the first embodiment, the upper end or the lower end of the paper discharge abutting portion 205 is displaced to absorb the collision sound. In the second embodiment, the collision sound is generated on the entire surface of the paper discharge abutting portion 205. Since the absorption noise is absorbed, the collision noise can be similarly reduced regardless of the position of the discharged sheet stopper 205 where the discharged sheet S comes into contact. Since the lower end portion 205a of the portion 205 can be eliminated, it is possible to prevent damage caused by something caught on the paper discharge contact portion 205.

  The present invention is not limited to this. For example, another image forming apparatus such as a copying machine or a printer, an image reading apparatus such as a scanner, or a multifunction machine type image forming apparatus having a combination of these functions as appropriate. The same effect can be obtained by applying the present invention to a sheet conveying apparatus in the image forming apparatus or the image reading apparatus.

<Other embodiments>
As mentioned above, although this invention was demonstrated in detail based on embodiment, this invention is not limited to embodiment mentioned above, The following aspects are included.

  In the present invention, in order to improve the alignment of the sheets on the sheet discharge tray in the sheet conveying apparatus, the sheet stacking position is set within a predetermined range by bringing the leading end of the sheet into contact with the sheet discharge stopper on the sheet discharge tray. Is limited to The sheet conveying apparatus can convey sheets of the same size, for example, but separates and conveys one sheet at a time from a bundle of sheets of different sizes such as various width dimensions and length dimensions. It is also applicable to.

  In that case, the sheet feeding unit in the sheet conveying apparatus is provided with a sheet separating unit that separates the sheets one by one, conveys the sheets one by one while separating them, and finally puts them on the discharge tray. Sequentially discharged. For this reason, it is preferable that the sheet discharge tray has a configuration that can be extended to accommodate sheets having various lengths.

  Specifically, as shown in FIGS. 16, 17, and 18, a discharge tray 600 is provided so as to be foldable by a rotary hinge 601 with respect to the apparatus main body 501 of the sheet conveying apparatus 500, and the discharge tray 600 is arranged in one stage. A second tray (second discharge tray) 620 may be pulled out from the second tray (first discharge tray) 610.

  At this time, for example, as shown in FIG. 16A, a paper discharge stopper 650 is rotated and erected on the first first paper discharge tray 610 that is rotatably connected to the apparatus main body 501. As a result, the leading edge of the sheet S discharged in the sheet discharge direction (the x direction in the figure) is brought into contact, the discharge position on the first discharge tray 610 is limited, and the discharged sheet S Alignment can be improved.

  In the case where such a discharge stopper 650 is accommodated so as to be flush with the sheet receiving surface 610a of the first discharge tray 610, the trailing end of the preceding sheet discharged onto the sheet receiving surface 610a follows. When the leading edge of the sheet comes into contact with the sheet and is pushed out, the alignment of the sheet may be disturbed, and the subsequent sheet may sink into the sheet receiving surface 610a side of the preceding sheet, and the stacking order of the discharged sheets may be disturbed. .

  In order to prevent the discharged sheet from being disturbed in this way, as shown in FIG. 16B, the discharge stopper 650 may be stopped in a posture inclined to the side opposite to the apparatus main body 501 side.

  As shown in FIG. 16B, the preceding sheet S1 to be ejected rides on the sheet ejection stopper 650 inclined like a jumping table in this way and easily stops on the apparatus main body 501 side. For this reason, the succeeding sheet S2 is landed on the preceding sheet S1 and discharged one after another.

  That is, the preceding sheet S1 is not pushed out by the succeeding sheet S2, and the succeeding sheet S2 does not sink under the preceding sheet S1. Therefore, it is possible to stack the sheets on the paper discharge tray 600 in the same order as the sheet bundle before feeding with good alignment.

  Note that when discharging a relatively long sheet, the discharge stopper 650 is inclined and stopped as shown in FIG. 16B, and when discharging a relatively short sheet, the discharge stopper 650 is illustrated. As shown in FIG. 16 (a), it may be used by raising it on the paper discharge tray 600 at a substantially right angle.

  Further, when it is desired to further improve the sheet alignment, as shown in FIG. 17, in the direction of lifting the front end of the discharge tray 600 while tilting the discharge stopper 650, as in the state shown in FIG. You may tilt.

  For example, as shown in FIG. 17, such a change in the posture of the discharge tray 600 is performed by placing a tray support portion 550 provided at the lower end 501 a of the apparatus main body 501 between the apparatus installation surface and the discharge tray 600. The posture of the paper discharge tray 600 with respect to the apparatus main body 501 may be changed in the lifting direction.

  As a result, the preceding sheet S1 discharged onto the paper discharge tray 600 stops more on the apparatus main body 501 side, so that the subsequent sheet S2 can easily land on the preceding sheet S1, and as a result, the sheet discharge alignment property. Can be further improved.

  Further, the example in which the paper discharge stopper 650 described above is provided in the first paper discharge tray 610 directly connected to the apparatus main body 501 side has been described. However, the present invention is of course not limited to this, and for example, FIG. ), It may be provided on a second discharge tray 620 extending from the first discharge tray 610.

  Further, as shown in FIG. 18B, the second discharge tray 620 may be accommodated in the first discharge tray 610 and extended from the state shown in FIG. 18A. As shown in FIG. 18 (c), the second discharge tray 620 together with the discharge stopper 650 may be stored in a storage space or groove in the first discharge tray 610.

  Further, as shown in FIG. 18D, when the second discharge tray 620 is pulled out from the first discharge tray 610 and extended, it is discharged by a biasing means (not shown) (for example, a leaf spring or a coil spring). The paper stopper 650 may be biased to an engaging portion that stops at a predetermined angle, and the paper discharge stopper 650 may be automatically protruded to a predetermined angle. Then, when the second paper discharge tray 620 is stored again from the state shown in FIG. 18D, it may be automatically stored as shown in FIGS. 18A and 18B. Further, it may be started up manually from the state of FIG. 18 (d) to the state of FIG. 18 (a).

  With the structure as shown in FIG. 18, the discharge stopper 650 is automatically pulled out only by the operation of extending the second discharge tray 620, so that the user operability can be improved. In addition, even when a sheet that is long enough to extend the tray is discharged, it is possible to get on the discharge stopper 650 and land the succeeding sheet S2 more reliably on the preceding sheet S1. As in the case described with reference to FIG. 16, the alignment of sheets can be improved. 18 may be applied to the structure of the tray support 550 described with reference to FIG. 17 to further improve sheet alignment.

  Note that the sheet discharge stopper 650 described above can improve the sheet discharge alignment property if it has a structure such as a jumping base inclined at a predetermined angle so that the preceding sheet S1 rides on. The angle may be changed in one step, but the angle may be adjusted in multiple steps. As a result, the sheet discharge alignment can be adjusted more finely, and good sheet discharge and alignment desired by the user can be realized.

  Further, the above-described sheet discharge stopper 650 shown in FIGS. 16 and 17 is provided so as to be able to stand up to a right angle with respect to the sheet receiving surface 610a. However, the present invention is not limited to this, and the sheet receiving surface 610a is of course not limited thereto. You may make it rotate to the state inclined so that it may become an acute angle instead of a right angle. Here, in order for the sheets to pass over the discharge stopper portions one after another, the discharge stopper does not simply stop the sheet discharge, but serves as a discharge guide for guiding the sheet discharge. have. The following description will be made with a paper discharge stopper for the sake of convenience, but it may be a paper discharge guide.

  As shown in FIGS. 19 and 20, when the second paper discharge tray 620 is pulled out from the first paper discharge tray 610, it automatically pops up to a predetermined angle to improve user operability. it can. Note that the extension of the second discharge tray 620 assumes that a sheet having a large discharge size (for example, an A3 size sheet) is received. It is preferable to improve the property. Therefore, it is preferable to pop up the discharge stopper (discharge guide) 650 to a predetermined angle in conjunction with the operation of extending the tray.

  FIG. 19 is a schematic view of the paper discharge tray 600 as viewed from above, and FIG. 20 is a diagram showing structural changes in the AA cross section and the BB cross section of FIG.

  As shown in FIGS. 19 and 20, the paper discharge stopper 650 is connected to the first paper discharge tray 610 so as to be rotatable to a predetermined angle by a rotating shaft 651 and a coil spring 652 at both ends.

  Further, around the rotation axis of the paper discharge stopper 650, both end portions in the width direction of the paper discharge tray 600 perpendicular to the advancing / retreating direction (extension / contraction direction) of the second paper discharge tray 620 (AA cross section in FIG. 19). Are partially provided with eccentric cams 653 as shown in FIG.

  On the other hand, an engaging portion 654 having a notch portion 654a is provided in the central portion of the paper discharge stopper 650, that is, in the vicinity of the central portion in the width direction of the paper discharge tray 600. On the inner wall surface 611 of the first paper discharge tray 610, an engaged portion 613 that is urged by a biasing means 612 such as a spring in the advancing and retreating direction of the second paper discharge tray 620 is provided to be engageable.

  Further, at the end of the second paper discharge tray 620 on the first paper discharge tray 610 side, a flat portion 621 and a taper portion 622 corresponding to the eccentric cam 653 of the paper discharge stopper 650 and a portion to be engaged 613 are supported. And the press part 623 which presses the said to-be-engaged part 613 by a level | step difference is provided.

  Here, a configuration in which the discharge stopper 650 is interlocked with the advancement / retraction of the second discharge tray 620 will be described. As shown in FIG. 20A-1, when the second discharge tray 620 is accommodated in the first discharge tray 610, the flat surface of the eccentric cam 653 is formed by the flat portion 621 of the second discharge tray 620. 653a is in surface contact, and the rotation of the discharge stopper 650 is restricted. That is, the upper surface 650 a of the paper discharge stopper 650 and the sheet receiving surface 610 a of the first paper discharge tray 610 are substantially flush with each other, and the paper discharge stopper 650 is accommodated in the groove portion of the first paper discharge tray 610. . At this time, in the central portion in the width direction of the paper discharge stopper 650, the pressing portion 623 of the second paper discharge tray 620 is engaged with the first discharge tray 610 as shown in FIG. The joining portion 613 is pushed in, and the engaging portion 654 (notch portion 654a) of the paper discharge stopper 650 and the engaged portion 613 are engaged.

  Next, as shown in FIG. 20B-1, when the second discharge tray 620 is pulled out from the first discharge tray 610 and extended, the flat portion 621 of the second discharge tray 620 becomes the eccentric cam 653. When the tapered portion 622 reaches the position of the eccentric cam 653 in sliding contact with the flat surface 653a, the engagement between the eccentric cam 653 and the second discharge tray 620 is released, and the discharge stopper 650 is moved by the biasing means 652. It rotates around the rotation axis S. As a result, the paper discharge stopper 650 pops up to a predetermined angle. At this time, when the second discharge tray 620 is pulled out from the first discharge tray 610 at the center in the width direction of the discharge stopper 650, the pressed state of the engaged portion 613 by the pressing portion 623 is released. Since the paper discharge stopper 650 is rotated, the engaged portion 613 is in contact with the end of the engaging portion 654.

  Next, as shown in FIG. 20 (c-1), if the user manually stores the paper discharge stopper 650 in the first paper discharge tray 610 with the second paper discharge tray 620 extended, the paper is discharged as it is. When the paper stopper 650 is pushed in and rotated around the rotation axis S, as shown in FIG. 20 (c-2), the engagement portion 654 (the notch portion 654a) of the second discharge tray 610 is engaged. 613 is engaged, and the paper discharge stopper 650 is in a rotation-stopped state. Accordingly, the user can manually store the paper discharge stopper 650 when the paper discharge stopper 650 is unnecessary. In this state, when the second paper discharge tray 620 is pushed into the first paper discharge tray 610, the state returns to the state of FIG. 20 (a-1) and FIG. 20 (a-2).

  In this way, if the paper discharge stopper 650 is automatically popped up as the second paper discharge tray 620 advances and retreats, it is possible to save the user from lifting the paper discharge stopper 650. It is also possible for the user to hold down the paper discharge stopper 650 when it is not needed.

  In addition, this invention is not limited to the form mentioned above, For example, it is not necessary to provide the engaging part 654, the to-be-engaged part 613, etc. in FIG.19 and FIG.20. Accordingly, the discharge stopper 650 can be automatically moved up and down based on the advance / retreat of the second discharge tray 620. In the present invention, the above-described discharge stopper 650 may be manually started up. In any case, by aligning and raising the paper discharge stopper 650 at an arbitrary angle, the paper discharge alignment can be improved.

  Further, as described in FIG. 17, another embodiment of the configuration in which the leading end of the discharge tray is tilted while tilting the discharge stopper as described in FIG.

  FIG. 21 is a schematic cross-sectional view of a sheet conveying apparatus according to another embodiment of the present invention. As shown in FIG. 21A, in the tray storage state, the paper discharge tray unit 700 is turned and folded by the rotary hinge (second hinge) 700a toward the apparatus main body 901 serving as the apparatus casing. In the first position, the first paper discharge tray 710 is accommodated so as to overlap the front surface of the apparatus main body 901 and the second paper discharge tray 720 is overlapped to the upper surface of the apparatus (a surface substantially parallel to the transport path RT). Further, the paper feed tray 800 rotates around the rotation hinge 850 and is accommodated on the second paper discharge tray 720 so that the paper feed tray 800 and the paper discharge tray unit 700 are accommodated. It is like that. The order in which the paper discharge tray unit 700 and the paper feed tray 800 overlap is not limited to this, and the paper discharge tray unit 700 may be folded from above the paper feed tray 800.

  When the sheet is transported (when the sheet discharged from the paper discharge tray unit 700 is received), the paper feed tray 800 and the paper discharge tray unit 700 are deployed away from the apparatus main body 901 and receive the discharged sheet. Is a position (second position) in which

  In the present embodiment, the paper discharge tray unit 700 folded into the apparatus main body 901 includes an end of the conveyance path RT in the vicinity of the first hinge 750 in addition to the first paper discharge tray 710 and the second paper discharge tray 720. It has an opening 711 that communicates with a paper discharge port 901a that is an opening of the apparatus main body 901 that is a portion (exit). The opening 711 is formed between the end of the first discharge tray 710 on the apparatus main body 901 side and the lower end of the apparatus main body 901.

  Thus, only the paper feed tray 800 is rotated from the tray storage state so as to be able to feed paper, and the paper discharge tray unit 700 is folded toward the apparatus main body side and conveyed from the apparatus main body 901. Paper can be discharged. Even in this case, the discharge tray unit 700 is configured to have the first discharge tray 710 and the second discharge tray 720, so that the leading edge of the discharged sheet is the first sheet of the first discharge tray 710. Landing on the receiving surface 710a and proceeding toward the second sheet receiving surface 720a of the second sheet discharge tray 710 formed at a predetermined angle with respect to the first sheet receiving surface 710a. Alignment can be improved. Further, since it is possible to discharge a sheet while the discharge tray unit 700 is housed in the apparatus main body, it is determined that the discharge tray unit 700 need not be expanded, that is, a situation where alignment is unnecessary. It is possible to improve the usability of the user in the case of conveying the type of paper or one sheet.

  Further, in the paper discharge tray unit 700 according to the present embodiment, the angle θ1 formed by the first sheet receiving surface 710a, which is a surface that receives the sheet on the top surface of the first paper discharge tray 710, with the installation surface of the apparatus main body 901 is discharged. The sheet discharge direction x is provided at a position facing the discharge port 901a while making it smaller than an angle θ2 formed by the installation surface of the apparatus main body 901, more preferably smaller than θ2. In this way, after the leading edge of the discharged sheet has landed on the first sheet receiving surface 710a, the second discharge tray 720 provided to have a predetermined inclination with respect to the first sheet receiving surface 710a. It can be configured to proceed with respect to the second sheet receiving surface 720a, the amount of movement of the sheet with respect to the discharge direction X and the tray surface direction can be reduced, and the alignment of the sheets can be improved.

  Further, as shown in FIG. 21B, a tray support portion 903 provided at the lowermost part of the apparatus main body 901 is brought into contact with the paper discharge tray unit 700 of this embodiment from below the first paper discharge tray 710. Accordingly, the posture of the discharge tray unit 700 with respect to the apparatus main body 901 may be changed in a lifting direction.

  In this way, in addition to the effect of improving the alignment by adopting the folded paper discharge tray unit 700 as described above, the use of the tray support portion 903 further improves the alignment of the sheets. become able to. On the other hand, the paper discharge tray unit 700 may be used without using such a tray support portion 903, and the paper discharge tray unit 700 may be used in consideration of sheet alignment. For example, although not particularly limited, the tray support portion 903 may not be used when discharging a relatively thin sheet, and the tray support portion 903 is used when discharging a relatively thick sheet. You just have to do it. Thus, the user can arbitrarily select the proper use of the paper discharge tray unit 700.

  Also in this embodiment, a protrusion 902 that protrudes in the surface direction of the installation surface is provided at the lowermost portion on the front end side of the apparatus main body 901 so that the tray support 903 is pulled out above the protrusion 902. Is provided. According to this configuration, although not shown, the center of gravity of the apparatus main body 901 can be stabilized by the protrusion 902 even when only the upper unit side is expanded to open the transport path RT of the apparatus main body 901. The tray support portion 903 can be easily brought into contact with the back surface of the first discharge tray 710 of the discharge tray 700, which is preferable.

  Further, the present invention is not limited to the configuration in which the posture of the discharge tray unit 700 is changed by the tray support portion 903 as described above. For example, in the rotary hinge 750 that connects the discharge tray unit 700 and the apparatus main body 901. The stepwise angle adjustment in the rotational direction of the discharge tray unit 700 may be possible, and a tray support portion that can be stored on the back surface of the first discharge tray 710 of the discharge tray unit 700 is provided. Accordingly, the posture of the paper discharge tray unit 700 may be changed by pulling out the tray support portion from the first paper discharge tray 710. As described above, the present invention adopts a bent discharge tray to improve the discharge alignment, and further changes the posture (angle, etc.) of the bent discharge tray, thereby further improving the discharge alignment. Can be increased. As described above, according to the present invention, not only when sheets of the same size are discharged one after another at a high speed, but also when sheets of different sizes are discharged one after another at a high speed, sufficient discharge alignment can be realized. It is extremely advantageous for increasing the sheet discharge speed.

  In order to improve the paper discharge alignment, there is a method of reducing the conveyance speed in the vicinity of the paper discharge outlet. However, if the above-described configuration is adopted, the paper discharge alignment can be improved without decelerating in the vicinity of the paper discharge outlet. If the speed is reduced near the discharge port, the throughput of the entire apparatus is reduced. Therefore, it can be said that the throughput of the conveyance can be improved by adopting the configuration of the present embodiment.

  As described above, the present invention has been described in detail based on various embodiments. However, by combining the above-described embodiments, the discharge alignment property may be further improved.
