When various commands and image data are received via the controller I/F 201 , the print controller 202 temporarily stores them in the RAM 204 . The print controller 202 causes the image processing controller 205 to convert the stored image data into print data so that the print head 8 can be used for printing operations. When print data is generated, the print controller 202 causes the print head 8 to perform a print operation based on the print data via the head I/F 206 . At this time, the print controller 202 drives the feeding units 6A and 6B, the transport rollers 7, the ejection rollers 12, and the flapper 11 shown in FIG.

While the recording medium S is conveyed by the conveyance control unit 207, the recording head 8 performs a recording operation according to instructions from the print controller 202, and print processing is performed.

The head carriage control unit 208 changes the direction and position of the recording head 8 according to the operating state such as the maintenance state and recording state of the recording apparatus 1 . The ink supply control unit 209 controls the ink supply unit 15 so that the pressure of the ink supplied to the recording head 8 is within an appropriate range. The maintenance control unit 210 controls operations of the cap unit 10 and the wiping unit 17 in the maintenance unit 16 when performing maintenance operations on the recording head 8 .

In the scanner engine unit 300 , the main controller 101 controls hardware resources of the scanner controller 302 while using the RAM 106 as a work area according to programs and various parameters stored in the ROM 107 . As a result, various mechanisms provided in the scanner section 3 are controlled. For example, the main controller 101 controls the hardware resources in the scanner controller 302 via the controller I/F 301 to transport the document placed on the ADF by the user via the transport control unit 304 , and the sensor 305 read. The scanner controller 302 stores the read image data in the RAM 303 . The print controller 202 converts the image data acquired as described above into print data, thereby making it possible for the print head 8 to execute a print operation based on the image data read by the scanner controller 302. .

FIG. 8 is an enlarged detailed view showing the lifting means 240, the pressing means 220, the air blower 223 and the discharge tray 13 in this embodiment. As described above, the printing apparatus 1 of the present embodiment is provided with the lifting means 240, the pressing means 220, and the air blowing section 223 as the air blowing means at the tip of the discharge port 20. FIG. The lifting means 240 has a projecting member 241 that is movable forward and backward with respect to the mounting surface 131 of the discharge tray 13 by a motor (not shown). The convex member 241 has a movable lifting portion 248 at a position protruding upward from the mounting surface 131 , and the lifting portion 248 comes into contact with the recording medium S on the discharge tray 13 and lifts the recording medium S. The lifting portion 248 of the projecting member 241 is movable between a first position positioned so as to protrude upward from the mounting surface 131 and a second position positioned flush with or below the mounting surface 131 . At the second position, the convex member 241 lifts the recording medium S on the ejection tray 13 away from the mounting surface 131 .

The pressing means 220 is composed of a contact member 221 and a holding member 222 , and the contact member contacts and presses the recording medium S placed on the discharge tray 13 . Further, the pressing means 220 can move between a pressing position for pressing the recording medium S and a retracted position for not contacting the recording medium S to be ejected. The contact member 221 is rotatable around a rotation axis perpendicular to the ejection direction of the recording medium S, and a plurality of contact members 221 are provided on the same rotation axis. The holding member 222 is a member that rotatably holds the contact member 221 , and the holding member 222 itself is also rotatable on a rotation axis different from that of the contact member 221 .

The guide portion 233 is formed such that the distance from the discharge tray 13 gradually narrows as the distance from the discharge port increases. By gradually narrowing the conveying path, even if the discharged recording medium S is curled, it becomes possible to convey the recording medium S to the contact portion 228 while gradually correcting the curl, resulting in a conveying failure. can be discharged without causing The recording medium S that has moved to the contact portion 228 is inserted between the contact portion 228 and the mounting surface 131 so as to be sandwiched between the contact member 221 and the mounting surface 131 .

FIG. 8(d) shows how the recording medium S2 on which the recording operation has been subsequently performed is ejected from the state of (c). When the recording medium S2 is ejected from the ejection port 20, it passes between the already placed recording medium S and the air blowing section 223. Therefore, the air from the air blowing section 223 is blocked by the recording medium S2, and the recording medium S2 is ejected onto the ejection tray 13. The function of suppressing the floating of the recording medium S is not fulfilled. However, since the protrusion member 241 exerts a hanging force on the trailing edge of the recording medium S, the trailing edge is less likely to rise than when the recording medium S is placed on a flat surface. To prevent defective conveyance caused by winding.

8E shows a state in which a plurality of recording media S are stacked on the discharge tray 13. FIG. Since the contact member 221 is rotatably held by the holding member 222, when the recording operation is continuously performed, the contact member 221 rotates so as to follow the change in the stacking height of the recording medium S, and the recording medium S is rotated. Even if they are piled up on the discharge tray 13, an appropriate pressing force continues to be applied. Further, the rotation of the contact member 221 also changes the positional relationship between the guide portion 233 and the discharge tray 13 and changes the transport path. In the present embodiment, the pressing force of the contact member 221 can be adjusted by changing the balance of the weight of the contact member 221 using a pressing force adjustment unit 229, which will be described later. Furthermore, although the central portion of the recording medium S placed on the ejection tray 13 in the ejection direction is lifted by the projecting member 241, the rear end near the ejection port 20 is subjected to the force of the air blowing portion 223 and the hanging down force. , is pressed against the mounting surface 131 . Therefore, compared to the case where the projecting member 241 is not provided, there is no need to increase the height H from the end of the discharge tray 13 on the side of the discharge port 20 to the discharge port 20, thereby avoiding an increase in the size of the apparatus.

The predetermined pressing force applied to the recording medium S by the contact member 221 regulates the movement of the recording medium S on the discharge tray 13 , and the end of the recording medium S on the leading end side is the contact portion 228 and the discharge tray 13 . It is large enough to allow passage between That is, when the subsequent second recording medium is discharged on top of the first recording medium previously placed on the discharge tray 13, the second recording medium pushes away the contact portion 228 and contacts the first recording medium. It enters between the portion 228 and the first recording medium. By the above operation, the recording medium S ejected from the ejection port 20 is sandwiched between the contact member 221 and the ejection tray 13 and held in an aligned state.

The contact member 221 is arranged at a position to press the end of the ejected recording medium S on the leading end side in the ejecting direction, and the air blower 223 is positioned to blow air to the end of the ejected recording medium S on the trailing end side in the ejecting direction. are placed in The positional relationship between the contact member 221 and the air blower 223 is an important feature of this embodiment. In this manner, the trailing edge of the recording medium S is pressed by the wind force of the air blower 223, and the leading edge is pressed by the contact member 221, thereby suppressing the floating of both the leading edge and the trailing edge of the ejected recording medium S. can do. That is, it is possible to prevent the edge of the recording medium S placed on the discharge tray 13 from floating, hindering the next discharging operation of the recording medium S, and preventing deterioration of the alignment of the recording medium S. Furthermore, by pressing the recording medium S with the contact member 221 and fixing the mounting position of the recording medium S, alignment on the discharge tray 13 can also be improved.

When printing is completed, the lifting means 240 moves to the second position and the pressing means 220 moves to the retracted position, returning to the arrangement shown in FIG. 8(a). The reason for returning the position is that it is difficult to take out the recording medium S if the contact member 221 remains lowered. This is because, depending on the type of , there is a habit of forming mountains. Since some types of recording media do not have peculiarities, it is not always necessary to have a configuration in which the convex member 241 can be moved to the second position for operation. A similar ejection failure prevention effect can be obtained.

FIG. 9 is a detailed view showing the positional relationship in the ejection direction between the lifting means 240, the pressing means 220, and the ejection tray 13 when a plurality of recording media S are stacked on the ejection tray 13. As shown in FIG. The discharge tray 13 is inclined upward in the vertical direction from the end on the discharge port 20 side as the distance from the discharge port 20 increases. In addition, the discharge tray 13 has a regulation member 224 extending vertically upward at the end on the discharge port 20 side. The regulating member 224 prevents the recording medium S from falling from the discharge tray 13 along the inclination when the pressing force with which the contact member 221 presses the recording medium S is insufficient for some reason. The regulating member 224 is arranged directly below the ejection roller 12 , and when the trailing edge of the recording medium S is pulled out of the ejection roller 12 , the regulating member 224
This prevents the subsequent paper from being improperly transported due to leaning against 24.例文帳に追加Although the discharge tray 13 is inclined at a certain angle in this case, it may be a tray extending horizontally.

On the discharge tray 13, the horizontal distance from the contact portion 228 where the contact member 221 presses the recording medium S to the end of the recording medium S on the discharge port 20 side is L1, and the contact portion 228 to the regulating member is L1. 224 is defined as L2. L1 is configured to be shorter than L2, and a clearance L is ensured between the ejected recording medium S and the regulation member 224. As shown in FIG. By providing the clearance L, it is possible to prevent the edge of the recording medium S from contacting the regulating member 224 and bending. When the recording medium S contacts the regulating member 224 and bends, the recording medium S may clog the discharge port 20 and cause an ejection failure. . However, if the air volume is excessively large, the leading edge of the recording medium S may be buckled by the wind during ejection, which may cause a jam on the ejection tray 13 or poor alignment. Therefore, it is desirable to suppress the air volume as much as possible. In this embodiment, the contact member 221 holds the ejected recording medium S and secures the clearance L, thereby preventing the recording medium S from coming into contact with the regulating member 224 and bending. It is possible to suppress the amount of air blown from 223.

Further, detailed configurations of the contact member 221 and the holding member 222 will be described with reference to FIG. The contact member 221 has a contact portion 228 that presses the recording medium S and a guide portion 233 that guides the recording medium S to the contact portion 228 . The contact member 221 is rotatably attached to the holding member 222 about a rotation center 227 , and presses the recording medium S discharged to the discharge tray 13 with a contact portion 228 . If the pressing force by the contact member 221 is too low, the ejected recording medium S cannot be held, and the recording medium S slides down toward the regulating member 224 along the inclination. Clearance L cannot be secured. If the pressing force is too high, the recording medium S cannot pass between the contact portion 228 and the discharge tray 13 or between the recording medium S and the recording medium S cannot be held. Therefore, it is necessary to appropriately manage the pressing force so that the mounting position of the recording medium S can be fixed and the recording medium S can be allowed to pass through the pressing portion.

Further, the horizontal distance from the contact portion 228 to the lifting portion 248 that contacts the recording medium S is defined as L3, and the distance from the lifting portion 248 to the regulating member 224 is defined as L4. In this embodiment, the lengths of L3 and L4 are configured to be substantially the same. If L4 is short, the force of the recording medium S hanging down due to its own weight will be small, making it difficult to suppress the trailing edge lifting due to curling. Conversely, if L4 is long, the height of the projecting member 241 approaches the discharge port 20, and the leading edge of the recording medium S being discharged collides with the projecting member 241, increasing the possibility of occurrence of conveyance failure. Furthermore, the force of the leading end of the recording medium S to hang down is also reduced, and there is a possibility that the curling of the recording medium S cannot be suppressed only by the contact member 221 . Therefore, in order to take advantage of the ejection failure prevention effect, the convex member 241 needs to be arranged at an appropriate position. Also, if the protrusion amount H2 corresponding to the vertical height of the convex member 241 from the mounting surface 131 is small, the force of the recording medium S hanging down becomes weak, and curling may not be sufficiently suppressed. Conversely, if H2 is set too high, the leading edge of the recording medium S being ejected collides with the convex member 241, which increases the possibility of conveyance failure. There is a need. In this embodiment, H2 is set to 15 mm.

In this embodiment, the contact member 221 has a pressing force adjustment portion 229 for adjusting the pressing force on the side opposite to the contact portion 228 across the rotation center 227 . By increasing the weight of the pressing force adjusting portion 229, the pressing force is decreased, and conversely, by decreasing the weight thereof, the pressing force is increased. That is, by adjusting the weight of the pressing force adjustment unit 229, it is possible to adjust the pressing force to suit various recording media and device configurations. As another embodiment, it is also possible to manage the pressing force by applying an urging force in the direction in which the contact member 221 rotates using an urging member such as a torsion coil spring.

FIG. 10 shows the positional relationship between the convex member 241, the contact member 221 and the air blower 223. As shown in FIG. In this embodiment, the lifting means 240 includes a plurality of projecting members 241, and projecting members 241a on the back side of the device and projecting members 241b on the front side of the device are arranged side by side in the width direction. 10A and 10B are a top view and a perspective view showing the contact member 221, the air blower 223, the convex members 241a and 241b when the recording apparatus 1 is in the printing state. 10C and 10D are a top view and a perspective view showing the contact member 221, the air blower 223, the convex members 241a and 241b when the recording apparatus 1 is in the standby state. The widthwise length W, which is the length from the rear end of the projection member 241a arranged side by side to the front end of the projection member 241b, is equal to the widthwise length of the recording medium S. It is provided so as to have substantially the same length. When the widthwise length W of the projecting member 241 is extremely shorter than the widthwise length of the recording medium S, the widthwise end of the recording medium S hangs down so as to come into contact with the mounting surface 131 of the discharge tray 13. The leading and trailing edges are prevented from drooping, and the force to hold the curl is reduced. Therefore, it is desirable that the widthwise length W of the convex member 241 is equal to or greater than the widthwise length of the recording medium. In this embodiment, the widthwise length W of the convex member is fixed, and the length is determined based on the length of the maximum width of the recording medium. may be changed according to the As a configuration for making the length of the convex member variable in the width direction, there is a configuration in which more convex members are provided and driven by a necessary amount according to the recording medium to be ejected, or a configuration in which the convex member can be expanded and contracted in the width direction. A configuration formed of an elastic member or the like is conceivable.

As shown in FIGS. 10(a) and 10(b), when the lifting portions 248a and 248b of the convex members 241a and 241b are at the first position, they protrude from the mounting surface 131 with the same height and shape, thereby recording. A medium S is uniformly lifted in the width direction. On the other hand, as shown in FIGS. 10(c) and 10(d), when the lifting portion 248a is at the second position, the convex member 241a forms the same surface as the mounting surface 131, and the lifting portion 248b is positioned at the second position. When in the position, the convex member 241b as a whole is positioned so as to be recessed with respect to the mounting surface 131. As shown in FIG. In this embodiment, the front side of the device where the projecting member 241b is provided is open, and the operator can collect the recording medium S placed on the discharge tray 13 from the front side of the device. The loading surface 131 of the discharge tray 13 has a recessed portion 133 extending in the width direction between a loading area on which the recording medium S is loaded and a non-loading area on the front side of the device outside the loading area. is provided. A projecting member 241b serving as an end projecting member extending to the end of the discharge tray 13 moves into the recess so as to follow the recess 133, and is lower than the loading surface 131 at the boundary between the loading region and the non-loading region. configured to be located. That is, when the lifting portion 248b is at the second position, a space is created between the recording medium S placed on the ejection tray 13 and the projecting member 241b, so that the recording medium S can be easily taken out. The projecting member 241a is flush with the mounting surface 131, so that the recording medium S is held without being bent, and the recording medium S is prevented from sagging along the recessed projecting member 241b. In this embodiment, the lifting means is composed of two projecting members, but the same action and effect can be obtained even if the projecting member is made up of one and the same part or composed of a plurality of parts of three or more. .

Further, in this embodiment, two contact members 221 are provided in the width direction, and are arranged at positions for pressing the front end portion of the recording medium S in the discharge direction and the both end portions in the width direction. Similarly, two air blowing units 223 are also provided in the width direction, and are arranged at positions where the rear end portion in the discharge direction of the recording medium S and both end portions in the width direction are pressed by air. Furthermore, the blowing direction of the blowing unit 223 is determined by a duct (not shown in FIG. 10). That is, by providing a plurality of contact members 221 and air blowing units 223, the four corners of the recording medium S are pressed, the curling of the entire recording medium S on the ejection tray 13 is suppressed, and the alignment of the recording medium S is improved. can be done. In addition, since the convex member 241 lifts the central portion of the recording medium S, the effect of suppressing the curling of the recording medium S becomes more remarkable. That is, even if the duty of the ink ejected onto the recording medium S is not uniform in the discharge direction and the width direction, the pattern is printed only at the center and both ends of the paper, and the curl is uneven on the recording medium S, Curling of S can be suppressed appropriately.

Further, the two left and right contact members 221 shown in FIG. 10 are independently rotatably held by the holding member 222 . Therefore, even if there is a difference in curl amount between the left and right sides of the recording medium, the contact member 221 equalizes the state of the recording medium S, so that the recording medium can be pressed appropriately. A difference in the amount of curl between the left and right sides of the recording medium may be caused by a change in the left-right positional relationship between the contact member 221 and the discharge tray 13 due to dimensional tolerance, or a case where the duty of the ink ejected onto the recording medium S varies between the left and right sides. A different case is assumed. In the description of the present embodiment, the arrangement has been described with two locations on the left and right.

Next, the detailed configuration and operation of the lifting means 240 will be described with reference to FIG. FIGS. 11A and 11C are diagrams showing a state in which the recording apparatus 1 is in a standby state and the projecting members 241a and 241b do not protrude from the placement surface 131, respectively. 11B and 11D are diagrams showing a state in which the convex members 241a and 241b protrude above the mounting surface 131 and the recording medium S can be lifted. In this embodiment, the lifting means 240 is composed of convex members 241a and 241b, cam members 251a and 251b as drive members, and a shaft 261 to which the two cam members are connected. The projecting member 241a has a cam surface 242a and is rotatably attached to the discharge tray 13 with a rotating shaft 243a. A cam member 251a that lifts the projecting member 241a has a tip contact portion 252a that contacts the cam surface 242a of the projecting member 241a, and is rotatable on a rotation axis parallel to that of the projecting member 241a. A shaft 261 connected to the cam member 251a is connected to a motor (not shown) and driven by the motor. Similarly, the convex member 241b is in contact with the tip contact portion 252b of the cam member 251b on the cam surface 242b, and is rotatable on the rotating shaft 243b.

As shown in FIG. 11(a), when the recording apparatus 1 is in the standby state and the lifting means 240 is at the second position, when the shaft 261 rotates counterclockwise in the figure, the cam member 251a rotates accordingly. , the tip contact portion 252a contacts the cam surface 242a. When the cam member 251a connected to the shaft 261 continues to rotate, the convex member 241a rotates and lifts so that the lifting portion 248a protrudes above the mounting surface 131, thereby reaching the position shown in FIG. 11(b). Become. That is, the cam member 251a rotated by the shaft 261 moves the lifting portion 248a of the convex member 241a from the second position to the first position. Further, when the lifting portions 248a and 248b are at the first positions, that is, when the cam members 251a and 251b are fully raised, the weight of the recording medium S acts toward the center of the shaft 261. As shown in FIG. Therefore, even if a plurality of recording media S are stacked, the convex member 241a does not return from the first position to the second position due to its weight, and can hold the position. When the shaft 261 rotates clockwise from the state shown in FIG. 11B, the projecting member 241a drops due to its own weight or the force of a spring (not shown) and returns from the first position to the second position. With the above mechanism, the convex member 241 a is configured to be movable between a first position projecting upward from the mounting surface 131 and a second position flush with the mounting surface 131 . The projecting member 241 b has the same mechanism and configuration, and is configured to be movable between a first position projecting upward from the mounting surface 131 and a second position located below the mounting surface 131 . In this embodiment, a cam rotation mechanism is used, but other mechanisms such as a rack and pinion mechanism can also be used, and the present invention is not limited to this. In addition, in the embodiment, there are two stages, the first position and the second position, for the stop position of the projecting member, but the projecting member may be stopped at any position according to the type of medium. Further, even if the projecting members 241a and 241b are attached to the main body of the apparatus instead of the ejection tray 13, the same effect can be obtained.

FIG. 12 shows the fan 225 and the duct 226 that make up the air blowing section 223 . The wind of the fan 225 generated by the rotation of the blade passes through the duct 226 and blows onto the recording medium S stacked on the discharge tray 13 during or after discharge.

Here, the directions of the air blowing ports of the ducts 226 arranged in the width direction of the recording medium S are not symmetrical, but are inclined by angles α and β, respectively. This is because the blade rotates in the direction of the arrow shown in FIG. 11, and the generated wind has a rotational component in the blade rotation direction, and the width direction end of the recording medium S is pressed with a uniform force. is. That is, the orientation of the duct 226 is set so that the wind direction is symmetrical with respect to the recording medium S in the width direction, taking into account the rotational component of the blade. This is because, if there is a difference in pressing force between the left and right sides, a difference in the transport resistance that the recording medium S receives from the left and right sides may occur, and the alignment of the recording medium S may be affected.

As another embodiment, a wall is provided on the side opposite to the side from which the recording medium S stacked on the discharge tray 13 is taken out in the discharge section of the recording apparatus 1, so that air stays and pushes. It is conceivable that there may be cases where the pressure changes only on one side. In such a case, the pressing force in the width direction can be made bilaterally symmetrical by adjusting the blowing direction and position, such as changing the height direction of the fan 225 on the left and right.

When a specific size such as A4 or LTR is used for the recording medium S, the recording apparatus 1 of the present embodiment performs horizontal feeding in which the long side is set perpendicular to the conveying direction, and horizontal feeding in which the short side is set perpendicular to the conveying direction. The user can select and set the vertical feed to be set.

In the present embodiment, due to the configuration of the device such as the transport path, the curl of the recording medium S becomes particularly large, and in order to control the curl during lateral feeding that requires suppression of the curl on the discharge tray 13, the above-described The pressing means 220 and the air blower 223 are arranged at the position of . On the other hand, when the curl of the recording medium S is small and there is little need to suppress the curl, it is unnecessary to operate the pressing means 220 and the air blowing section 223, and paper jams may actually occur. . Therefore, when longitudinally feeding the recording medium S with less curl, the abutting member 221 and the holding member 222 are moved to the retracted positions as shown in FIG. By operating only under specific conditions, it is possible to appropriately reduce the occurrence of paper jams.

Furthermore, in the present embodiment, the positions of the lifting means 240 and the pressing means 220 are fixed, but it is possible to move them appropriately for each size of the recording medium S, so that more types of sizes can be handled. be.

13A and 13B are diagrams showing a mounting configuration of the holding member 222. FIG. A fixing member 230 is arranged at one end of the holding member 222 to press the holding member 222 in the direction of the rotation axis, and the holding member 222 and a drive transmission gear 231 are drivingly connected to each other by a meshing clutch mechanism at the opposite end. ing. Further, the drive transmission gear 231 is connected to a drive motor gear (not shown), and the holding member 222 can be rotated by the rotation of the motor. The holding member 222 , fixed member 230 and drive transmission gear 231 are attached to a holder 232 .

Since the holding member 222 is pressed toward the drive transmission gear 231 by the fixing member 230, the drive transmission is not interrupted even if the holding member 222 rotates. However, the drive can be released by manually moving the holding member 222 away from the drive transmission gear 231 in the direction of the rotation axis, which leads to an improvement in the ease of assembly.

With the configuration described above, it is possible to fix the mounting position of the recording medium while suppressing the curling of the recording medium on the discharge tray. Alignment of the placed recording medium can be improved.

In this embodiment, the lifting means has two protruding members arranged adjacent to each other in the width direction. . In addition, a configuration in which the convex member has a constant width in the transport direction and a configuration in which a plurality of convex members are provided in the transport direction can be effective especially when the size of the recording medium is large. Furthermore, although the cam members for lifting the convex members are connected to the same shaft, they may be connected to different shafts so that they can rotate individually.

(Modification 2)
In this embodiment, the structure is composed of two contact members and two blowers, but the same effect can be obtained with a structure in which the recording medium S is pressed by a single contact member or by three or more contact members. Alternatively, the air from one fan may be divided into a plurality of air blowing paths by ducts, and may be blown to two or more places. Furthermore, although the contact member has a constant thickness in the width direction from the guide portion to the contact portion, it may be shaped such that only the pressing portion at the tip is widened in the width direction.
