Then, the post-processed paper P is placed on the stacker (two in the present embodiment) 302 extending leftward from the left side surface of the post-processing apparatus 300.

Next, the structure of the printer 100 will be described.
As shown in FIG. 3, a recording unit 110 that performs recording on the paper P from the upper side in the vertical direction Z and a paper P that is conveyed along a conveyance path 120 in the recording device-side housing 101 of the printer 100. And a transport unit 130 for performing the operation. The transport path 120 is formed such that when the direction along the front-rear direction Y is the width direction of the sheet (medium) P, the sheet P is transported with the direction intersecting the width direction as the transport direction.

  The recording unit 110 includes a line head type recording head 111, which can simultaneously eject ink over substantially the entire widthwise direction of the paper P, in the lower portion. The recording unit 110 forms an image on the paper P by the ink ejected from the recording head 111 being attached to the recording surface (the surface on which the image is printed) facing the recording head 111 on the paper P.

  The transport unit 130 includes a plurality of transport roller pairs 131 arranged along the transport path 120, and a belt transport unit 132 provided immediately below the recording unit 110. That is, ink is ejected from the recording head 111 onto the sheet P conveyed by the belt conveying unit 132, and recording is performed.

  The belt transport unit 132 includes a driving roller 133 disposed upstream of the recording head 111 in the transport direction, a driven roller 134 disposed downstream of the recording head 111 in the transport direction, and each of these rollers 133. And an endless annular belt 135 that is hung on the belt 134. The drive roller 133 is driven and rotated to rotate the belt 135, and the rotating belt 135 conveys the paper P to the downstream side. That is, the outer peripheral surface of the belt 135 functions as a supporting surface that supports the paper P on which recording is performed.

  The transport path 120 includes a supply path 140 through which the paper P is transported toward the recording unit 110, a discharge path 150 through which the recorded paper P that has been recorded by the recording unit 110 is transported, and a discharge path 150. And a branch path 160 branching from the.

  The supply path 140 has a first supply path 141, a second supply path 142, and a third supply path 143. In the first supply path 141, the sheet P inserted from the insertion opening 141b exposed by opening the cover 141a provided on the right side surface of the recording apparatus side body 101 is conveyed to the recording unit 110. That is, the sheet P inserted from the insertion port 141b is linearly conveyed toward the recording unit 110 by the rotational driving of the first drive roller pair 144.

  In the second supply path 142, in the vertical direction Z, the paper P stored in each of the paper cassettes 103 provided under the recording apparatus side body 101 is conveyed to the recording unit 110. That is, among the sheets P stacked in the sheet cassette 103, the uppermost sheet P is sent out by the pickup roller 142a and separated one by one by the separation roller pair 145, and then the posture in the vertical direction Z is reversed. While being conveyed, it is conveyed toward the recording unit 110 by the rotational drive of the second drive roller pair 146.

  In the third supply path 143, when performing double-sided printing in which images are recorded on both sides of the paper P, the paper P of which one side has been recorded by the recording unit 110 is conveyed to the recording unit 110 again. That is, a branch path 160 that branches from the discharge path 150 is provided on the downstream side of the recording unit 110 in the transport direction. That is, when performing double-sided printing, the paper P is conveyed to the branch path 160 by the operation of the branch mechanism 147 provided in the discharge path 150. Further, the branch path 160 is provided with a branch path roller pair 161 capable of rotating in both forward and reverse directions, on the downstream side of the branch mechanism 147.

  At the time of double-sided printing, the sheet P having one surface printed is once guided to the branch path 160 by the branch mechanism 147, and is conveyed downstream in the branch path 160 by the pair of forward branch path rollers 161. After that, the paper P conveyed to the branch path 160 is reversely conveyed from the downstream side to the upstream side in the branch path 160 by the pair of reverse branch path rollers 161. That is, the conveyance direction of the sheet P conveyed on the branch path 160 is reversed.

  The paper P conveyed in the reverse direction from the branch path 160 is conveyed to the third supply path 143 and conveyed toward the recording unit 110 by the plurality of conveyance roller pairs 131. By being conveyed through the third supply path 143, the sheet P is inverted so that the other side not printed faces the recording section 110, and is conveyed toward the recording section 110 by the rotational driving of the third drive roller pair 148. To be done. That is, the third supply path 143 functions as a reverse conveyance path that conveys the paper P while reversing the posture of the paper P in the vertical direction Z.

  Of the supply paths 141, 142, 143, the second supply path 142 and the third supply path 143 convey the paper P toward the recording unit 110 while the attitude of the paper P is curved in the vertical direction Z. On the other hand, as compared with the second supply path 142 and the third supply path 143, the first supply path 141 conveys the paper P toward the recording unit 110 without the posture of the paper P being greatly curved. ..

  The paper P conveyed through each of the supply paths 141, 142, 143 is conveyed to the alignment roller pair 149 arranged on the upstream side in the conveyance direction with respect to the recording unit 110, and then the rotation of the alignment roller pair 149 is stopped. The tip hits. Then, the inclination of the sheet P with respect to the transport direction is corrected (skew removal) depending on the state in which the sheet P hits the alignment roller pair 149. Then, the sheet P whose inclination has been corrected is conveyed to the recording unit 110 in an aligned state by the subsequent rotational driving of the aligning roller pair 149.

  The recording unit 110 performs recording on one side or both sides, and the recording-completed sheet P is conveyed by the conveyance roller pair 131 along a discharge path 150 that constitutes a downstream portion of the conveyance path 120. The discharge path 150 is branched to the first discharge path 151, the second discharge path 152, and the third discharge path 153 at a position downstream of the position where the discharge path 150 is branched. That is, the recording-completed paper P is conveyed through the common discharge path (upstream discharge path) 154 that constitutes the upstream portion of the discharge path 150, and then the guide mechanism (switching) provided at the downstream end of the common discharge path 154. The guide portion) 180 guides to any one of the first to third discharge paths (downstream discharge paths) 151, 152, 153 forming the downstream portion of the discharge path 150.

  The first discharge path (upper discharge path) 151 is provided so as to extend above the recording apparatus side body 101 and to curve along the branch path 160. The paper P conveyed through the first discharge path 151 is discharged from a discharge port 155 that opens at a part of the recording apparatus side body 101 so as to be the end of the first discharge path 151. Then, the paper P discharged from the discharge port 155 falls to the lower side in the vertical direction Z, and is discharged to the mounting table 156 in a stacked state as shown by the chain double-dashed line in FIG. The sheet P is discharged from the discharge port 155 to the mounting table 156 with the recording surface facing down in the vertical direction Z from the discharge port 155 by the pair of transport rollers 131 arranged at a plurality of positions in the discharge path 150. It

  The mounting table 156 has a sloped shape that rises to the upper side in the vertical direction Z toward the right in the left-right direction X, and the sheets P are stacked on the mounting table 156 in a stacked state. At this time, each sheet P placed on the mounting table 156 moves to the left along the inclination of the mounting table 156, and the vertical side wall 157 provided below the discharge port 155 of the recording apparatus side body 101. Placed close to.

  Further, the first discharge path 151 has a curved reversal path 151 a that reverses the front and back of the paper P while the paper P recorded by the recording unit 110 is conveyed to the discharge port 155. That is, the curving/reversing path 151a bends the recording surface of the paper P recorded by the recording unit 110 so that the recording surface of the paper P is directed upward in the vertical direction Z in the vertical direction Z. The sheet P is turned upside down. Therefore, in the discharge path 150, the paper P is discharged from the discharge port 155 by passing through the curved reversal path 151a so that the recording surface at the time of single-sided printing faces the mounting table 156.

  The second discharge path 152 branches downward in the vertical direction Z from the first discharge path 151, and extends linearly from the recording section 110 toward the pull-out surface section 106 forming a part of the recording apparatus side body 101. There is. Therefore, the paper P conveyed through the second discharge path 152 is not conveyed in a curved posture like the first discharge passage 151, and the posture is kept constant as in the case of passing the recording unit 110. The sheet is conveyed linearly and discharged from a discharge port 108 formed in the pull-out surface portion 106 to a paper discharge tray 109 attached to the pull-out surface portion 106. That is, the second discharge path 152 functions as a non-reverse discharge path that conveys the paper P toward the discharge tray 109 without reversing the attitude of the paper P in the vertical direction.

  The third discharge path (lower discharge path) 153 branches downward in the vertical direction Z from the second discharge path 152, and extends obliquely downward in the vertical direction Z so as to extend downward of the recording apparatus side body 101. Is extended. The downstream end thereof is connected to the upstream end of the introduction path 211 of the transport device 200 in the recording device side body 101. That is, the paper P conveyed through the third discharge path 153 is discharged to the conveying device 200.

  A part of the discharge path 150 and a part of the branch path 160 are attached to a drawer unit 170 provided in the recording device side body 101. The drawer unit 170 is connected to the drawer surface portion 106 so as to be integrally handleable. Therefore, the pull-out unit 170 is pulled out from the recording apparatus-side housing 101 by the pull-out surface portion 106 being pulled out, and is exposed from the recording apparatus-side housing 101.

  The drawer unit 170 includes a first path forming portion 171 that constitutes a part of the curved inner guide surface of the first discharge path 151 and a part of the curved outer guide surface of the branch path 160, and the branch path 160. A second path forming portion 172 that constitutes a part of the curved inner guide surface is rotatably attached about a shaft 173 provided in the drawer unit 170. That is, when the drawer unit 170 is pulled out, the path forming portions 171 and 172 rotate about the shaft 173 in the clockwise direction in FIG. 3 to expose the inside of the branch path 160 and the first discharge path 151. (See FIGS. 8 and 9).

  As shown in FIGS. 4 to 6, the guide mechanism 180 has a first guide portion 181 and a second guide portion 182. The guides 181 and 182 are provided at branch positions 190 where the downstream ends of the common discharge path 154 branch into the first to third discharge paths 151, 152, and 153, respectively, and the direction in which the paper P is conveyed from the recording unit 110. In the left-right direction X, where the first guide portion 181 is on the upstream side on the right side, and the second guide portion 182 is on the downstream side, the left side is displaced. Further, also in the vertical direction Z, the first guide portion 181 and the second guide portion 182 are displaced from each other so that they are located on the lower side and the upper side, respectively.

  Further, each of the guide portions 181 and 182 has shafts 185 and 186 at the base end portions 183 and 184, which are the left side portions on the downstream side in the left-right direction X that is the conveyance direction, and the shafts 185 and 186 are respectively attached. It is rotatably provided in the center. Each of the guide portions 181 and 182 is a right side portion on the upstream side in the left-right direction X that is the transport direction by rotating about the shafts 185 and 186 that the guide portions 181 and 182 have respectively. The positions of the tip portions 187 and 188 on the opposite side are vertically displaced in the vertical direction Z. That is, the guide portions 181 and 182 are separated from the first path forming portion 171 and the upper position where the respective tip portions 187 and 188 located on the upstream side in the transport direction of the paper P approach the first path forming portion 171. It is rotatably provided between two lower positions. By the way, as shown in FIG. 4, the leading end portion 187 of the first guide portion 181 is located upstream of the leading end portion 188 of the second guide portion 182 in the transport direction of the paper P.

  In other words, each of the guides 181 and 182 is selectively switched to the upper position or the lower position, and comes into contact with the paper P conveyed through the common discharge path 154, so that the paper P is first to third. To each of the discharge paths 151, 152, and 153. By the way, the guide portions 181 and 182 are formed in a comb-teeth shape, for example, from the base end portions 183 and 184 to the tip portions 187 and 188 so as not to hinder the mutual rotational movements, so that they do not interfere with each other. It is configured. The rotation operation of each of the guide units 181 and 182 is controlled by a control unit (not shown) included in the printer 100.

That is, in the state of FIG. 6, the guide mechanism 180 guides the sheet P conveyed through the common discharge path 154 to the third discharge path 153.

Next, the carrier device 200 will be described.
As shown in FIG. 7, an intermediate transport unit 220 that transports the paper P along an intermediate transport path (intermediate path) 210 is provided in the transport apparatus-side housing 201 of the transport apparatus 200. The intermediate conveyance path 210 is formed such that the sheet P is curved while being conveyed with a direction intersecting the width direction of the medium, which is a direction along the front-rear direction Y, as the conveyance direction.

  The intermediate transport unit 220 has a plurality of intermediate transport roller pairs 221 provided along the intermediate transport path 210. That is, the pair of intermediate conveyance rollers 221 rotationally drive the sheet P while sandwiching and supporting the sheet P from both front and back sides, so that the sheet P is conveyed along the intermediate conveyance path 210.

  The intermediate conveyance path 210 has an introduction path 211 that is connected to the downstream end of the third discharge path 153 of the printer 100 and that introduces the paper P into the conveyance device-side housing 201 at its upstream end. The introduction path 211 is provided at a position above the vertical direction Z in the introduction unit 202, and extends in the vertical direction from the inside of the recording apparatus side casing 101 on the upstream side in the conveying direction to the inside of the conveying apparatus side casing 201 on the downstream side. It extends diagonally downward and intersects Z. That is, the introduction path 211 is provided so as to penetrate a part of a side wall forming the left side surface of the recording apparatus side body 101 and a part of a side wall forming the right side surface of the transport apparatus side body 201. Further, a sensor 222 that detects the paper P that is conveyed through the introduction path 211 is provided at a downstream portion of the introduction path 211 that is located inside the transport device-side housing 201.

  The upstream end of the first branch path 212 and the upstream end of the second branch path 213 are connected to the downstream end of the introduction path 211 extending obliquely downward. The first branch path 212 branches upward from the downstream end of the introduction path 211 (to the left in FIG. 7) and extends so as to curve downward in the middle. The second branch path 213 branches while curving further downward (to the right in FIG. 7) from the downstream end of the introduction path 211, and then extends downward so as to meander. That is, the intermediate conveyance route 210 branches from the branch point A, which is the downstream end of the introduction route 211, into the first branch route 212 and the second branch route 213. Then, the sheet P conveyed on the introduction path 211 is guided to either the first branch path 212 or the second branch path 213 by the operation of the guide flap (guide portion) 223 provided at the branch point A. The guide flap 223 is driven based on a signal transmitted when the sensor 222 detects the paper P, and guides the paper P conveyed through the introduction path 211 to the first branch path 212 and the second position. The position is switched between the position for guiding to the branch route 213.

  As shown in FIG. 7, the upstream end of the first switchback path 214 is connected to the downstream end of the first branch path 212. The first switchback path 214 is slightly curved rightward in the left-right direction X from the middle thereof, and then extends downward in the vertical direction Z so as to approach the bottom surface 215a of the transport apparatus-side housing 201. That is, the downstream end of the first switchback path 214 is located at the lowest position in the first switchback path 214. Further, the path length of the first switchback path 214 in the carrying direction is configured to be equal to or longer than the medium length in the carrying direction of the paper P that can be recorded by the printer 100.

  In the first switchback path 214, a downstream portion, which is downstream of the curved portion, is configured by a guide 214a that supports the sheet P that is conveyed while being slightly curved rightward in the left-right direction X from the lower side in the vertical direction Z. .. Then, in the first switchback path 214, one sensor 224 for detecting the paper P conveyed on the first switchback path 214 is provided in the upstream part upstream of the curved portion, and in the forward and reverse directions. Two pairs of rotatable first reverse rollers 225 are provided. The two pairs of first reversing rollers 225 provided in the pair perform forward rotation driving or reverse rotation driving based on the signal transmitted when the sensor 224 detects the paper P. That is, the sheet P conveyed through the first switchback path 214 is conveyed (switched back) after the conveyance direction of the sheet P is reversed by the first reversing roller pair 225.

  Further, at the downstream end of the first branch path 212, the movement of the paper P from the first branch path 212 to the first switchback path 214 is permitted, while the first switchback path 214 to the first branch path 212 is allowed. A first regulation flap 226 that regulates the movement of the paper P is provided. The first regulation flap 226 is biased by a biasing member (not shown) so as to close the downstream end of the first branch path 212.

  On the other hand, as shown in FIG. 7, the downstream end of the second branch route 213 is connected to the upstream end of the second switchback route 215. The second switchback path 215 is provided so as to curve rightward in the left-right direction X from the middle thereof and then extend downward in the vertical direction Z. In the second switchback path 215, the downstream end of the upstream portion including the curved portion is open toward the right inner surface of the transport device-side housing 201. At a position facing the downstream end, a guide portion 215b is provided that extends in a curved manner from the right inner side surface of the carrier device side body 201 to the bottom surface 215a of the carrier device side body 201. That is, when the paper P is conveyed through the second switchback path 215, the front end of the paper P projects from the opened downstream end thereof, and the projected front end of the paper P is guided by the guide portion 215b, and the conveyance device side casing is formed. It is guided so as to go under the downstream end of the first switchback path 214 to the bottom surface 215a of the body 201.

  That is, the second switchback path 215 is configured to include the guide portion 215b and the bottom surface 215a of the transport device side body 201. Further, the path length of the second switchback path 215 in the carrying direction is configured to be equal to or longer than the medium length in the carrying direction of the paper P that can be recorded by the printer 100, as in the case of the first switchback path 214. There is. Of course, the downstream portion of the second switchback path 215, which is configured by the guide portion 215b and the bottom surface 215a of the transport device side body 201, may have the same configuration as the upstream portion, or may be configured by only the guide portion 215b. May be.

  Then, in the upstream portion of the second switchback path 215, one sensor 227 for detecting the paper P conveyed on the second switchback path 215 is provided at a position upstream of the curved portion, and the forward rotation direction and the reverse rotation direction are provided. One pair of second reversing rollers 228 rotatable in the direction is provided. In addition, another pair of the second reversing rollers 228 is provided in the upstream portion of the second switchback path 215 at a position downstream of the curved portion. The second pair of second reversing rollers 228 provided in two pairs performs forward rotation driving or reverse rotation driving based on the signal transmitted from the sensor 227. That is, the sheet P conveyed through the second switchback path 215 is conveyed (switched back) after the direction in which the sheet P is conveyed is reversed by the second pair of reversing rollers 228.

  Further, at the downstream end of the second branch path 213, movement of the paper P from the second branch path 213 to the second switchback path 215 is permitted, while on the other hand, from the second switchback path 215 to the second branch path 213. A second regulation flap 229 that regulates the movement of the paper P is provided. The second regulation flap 229 is biased by the biasing force of a biasing member (not shown) so as to close the downstream end of the second branch path 213.

  As shown in FIG. 7, the upstream end of the first merging path 216 is connected to the upstream end of the first switchback path 214. That is, the first joining path 216 extends while curving to the right in the left-right direction X from the first connection point B where the downstream end of the first branch path 212 and the upstream end of the first switchback path 214 are connected. .. The upstream end of the second merging path 217 is connected to the upstream end of the second switchback path 215. That is, the second merging path 217 extends in the left-right direction X while curving to the left from the second connection point C where the downstream end of the second branch path 213 and the upstream end of the second switchback path 215 are connected. .. The first merging path 216 and the second merging path 217 join at the merging point D located between the first switchback path 214 and the second switchback path 215.

  In other words, when the paper P is conveyed from the first branch path 212 to the first switchback path 214, the first regulation flap 226 opens the downstream end of the first branch path 212 due to the contact of the leading edge of the paper P. To be displaced. On the other hand, when the paper P is reversely conveyed (switched back) from the first switchback path 214, the first restriction flap 226 restricts the conveyance to the first branch path 212, and the paper P is first merged. You will be guided to route 216. Further, when the paper P is conveyed from the second branch path 213 to the second switchback path 215, the leading edge of the paper P comes into contact with the second regulation flap 229 to open the downstream end of the second branch path 213. To be displaced. On the other hand, when the paper P is reversely conveyed (switched back) from the second switchback path 215, the second restriction flap 229 restricts the conveyance of the paper P to the second branch path 213, and the paper P is second merged. You will be guided to route 217.

  The upstream end of the derivation path 218 is connected to the confluence point D where the downstream end of the first merging path 216 and the downstream end of the second merging path 217 are connected. The lead-out path 218 extends downward while curving so as to pass between the first switchback path 214 and the second switchback path 215 toward the post-processing apparatus 300, and then extends to the downstream end of the first switchback path 214. It circumvents the lower side and extends to the upper part of the lead-out portion 203. The downstream end of the lead-out path 218 penetrates a part of the left side wall of the transport device-side housing 201 and extends toward the post-processing device 300. That is, the intermediate conveyance route 210 includes the introduction route 211, the first branch route 212, the second branch route 213, the first switchback route 214, the second switchback route 215, the first merge route 216, the second merge route 217, and the like. It has a lead-out path 218. The positional relationship among the points A, B, C, D is arranged in the order of “A, B, D, C” from the top in the vertical direction Z, and “C, A, D, B from the right in the left-right direction X”. Are arranged in this order.

  In the present embodiment, the path lengths of the first branch path 212 and the second branch path 213 in the transport direction are substantially the same. Moreover, the path lengths of the first merging path 216 and the second merging path 217 are also substantially the same.

  Next, the operation of the printer 100 and the recording system 1000 including the printer 100 and the transport device 200 for eliminating the transport failure of the paper P will be described.

  In a recording apparatus that records on a sheet-shaped medium such as a sheet P and conveys the sheet P like the printer 100 illustrated in FIG. 3, a conveyance error such as a paper jam may occur during the conveyance of the sheet P along the path. May occur. In particular, in a recording apparatus that performs recording by ejecting a liquid such as ink onto a medium, the recording surface of the paper P expands and curls with a convex recording surface are more likely to occur. Poor conveyance is likely to occur on the downstream side. Therefore, in the printer 100 of the present embodiment, a part of the discharge path 150 and a part of the branch path 160 can be pulled out from the recording apparatus side body 101 in order to easily take out the paper P that is jammed during such conveyance. It has a unique structure.

  As shown in FIG. 8, when the paper P is jammed in the discharge path 150 and the branch path 160, the paper discharge tray 109 attached to the drawer surface portion 106 is first removed, and then the user pulls out the drawer surface portion 106. The pulling-out face portion 106 is pulled out along the pulling-out direction which is the leftward direction in the left-right direction X, which is the conveyance direction of the paper P, by holding the hand-holding portion 107 formed at. When the pull-out surface portion 106 is pulled out along the pull-out direction, the pull-out unit 170 is pulled out from the recording apparatus side body 101 together with the pull-out surface portion 106. That is, a part of the curved reversal path 151a, the second discharge path 152, the third discharge path 153, and the branch path 160 that configure the discharge path 150 is pulled out. Further, the guide mechanism 180 provided at the branch position 190, which is the downstream end of the common discharge path 154, is also pulled out to the outside of the recording apparatus side body 101.

  At this time, since the height of the introduction unit 202 that constitutes the conveyance device 200 attached to the left side of the printer 100 is formed to be lower than that of the lower portion of the drawer surface unit 106, the introduction unit 202 pulls out the drawer unit 170. When it is pulled, it does not interfere with the drawer surface portion 106 and the drawer unit 170. Further, the length of the introduction unit 202 in the left-right direction X is longer than the region (movement region) in which the drawer unit 170 moves in the left-right direction X, that is, the length in which the drawer unit 170 is pulled out from the recording device side body 101. Is formed. Therefore, the lead-out portion 203 formed to be higher than the lead-in portion 202 does not interfere with the pull-out surface portion 106 and the pull-out unit 170 when the pull-out unit 170 is pulled out. That is, the transport device 200 is formed so as to avoid a moving area when the pull-out unit 170 is pulled out from the recording device side body 101. If the pull-out unit 170 is configured to be able to be pulled out in a direction intersecting with the conveyance direction of the paper P, the paper P with the paper jam may be torn in the path when the pull-out unit 170 is pulled out. Therefore, it is preferable that the pull-out unit 170 be configured to be able to be pulled out in the direction along the conveyance direction of the paper P.

  As shown in FIG. 9, after pulling out the drawer unit 170 from the recording device side body 101, the first path forming portion 171 and the second path forming portion 172 attached to the drawer unit 170 are moved around the shaft 173. Rotate in the rotating direction. Then, the inner guide surface of the curved reversal path 151a forming the first discharge path 151 is separated from the outer guide surface, and the outer guide surface and the inner guide surface of the branch path 160 are separated from each other. By separating the outer guide surface and the inner guide surface of the curved reversing path 151a and the branching path 160 from each other, the inside of the path is opened, and the sheet P having the paper jam in the path can be taken out. Further, when the pull-out unit 170 is pulled out, the paper P may remain in the recording device side body 101 instead of in the pull-out unit 170. In this case, the paper P is pulled out by inserting a hand from the opening 105b formed above the paper cassette 103, and the conveyance failure is eliminated. The opening 105b formed in the frame 105 of the printer 100 is located at a position where at least a part of the drawer unit 170 overlaps the drawer unit 170 when viewed from the front-rear direction Y when the drawer unit 170 is not drawn out from the recording device side body 101. Has been formed.

Next, the operation when the printer 100 records on the paper P will be described.
As shown in FIG. 3, when recording on the paper P in the printer 100, recording is performed on either the paper P accommodated in the paper cassette 103 or the paper P inserted from the insertion port 141b. At this time, if recording is performed on a medium that cannot be accommodated in the paper cassette 103, particularly a medium having high rigidity such as thick paper, the thick paper is inserted from the insertion port 141b and conveyed to the recording unit 110 through the first supply path 141. It Since a medium such as a thick paper has a high rigidity and is difficult to be bent, if it is conveyed through the conveyance path 120 having a large degree of curving, a conveyance failure such as a paper jam may occur. Therefore, the first supply path 141 has a smaller degree of bending than the second supply path 142, and is a linear path that extends straight toward the recording unit 110.

  The thick paper recorded by the recording unit 110 is conveyed to any one of the first discharge path 151, the second discharge path 152, and the third discharge path 153 that form the discharge path 150. Here, when it is attempted to place the recorded thick paper on the mounting table 156, the thick paper is conveyed through the first discharge path 151. However, since the first discharging path 151 has the curved reversing path 151a that is largely curved, there is a possibility that defective conveyance may occur when the thick paper is conveyed. In addition, when the thick paper is to be placed on the stacker 302 of the post-processing device 300 from the third discharge path 153 via the transport device 200, it is necessary to provide the transport device 200 with a route with a small degree of bending. There is a possibility that the degree of freedom in designing the intermediate conveyance path 210 included in 200 may be reduced.

  Therefore, the printer 100 of the present embodiment is provided with the second discharge path 152 formed so as to extend straight along the common discharge path 154. That is, the cardboard that has passed through the recording unit 110 from the second supply path 142 and is conveyed through the common discharge path 154 and the second discharge path 152 always has the one surface on the upper side in the vertical direction Z when inserted into the insertion opening 141b. The paper is conveyed with it facing upward. Then, with one side serving as the recording surface facing upward, the sheet is discharged from the discharge port 108 and placed on the sheet discharge tray 109.

Next, an operation when the transport device 200 transports the paper P will be described.
As shown in FIG. 3, when the sheet P recorded by the recording unit 110 of the printer 100 is subjected to the post-processing, the sheet P is conveyed to the post-processing device 300 via the conveying device 200. That is, the recorded sheet P is guided from the common discharge path 154 to the third discharge path 153 by the branching mechanism 147 and introduced into the introduction path 211 in the recording device side body 101.

  As shown in FIG. 10A, the first sheet P<b>1 introduced into the conveyance device side body 201 is conveyed to the downstream side along the introduction path 211. Then, the guide flap 223 provided at the downstream end of the introduction path 211 is positioned so as to close the upstream end of the second branch path 213, so that the sheet P1 is guided to the first branch path 212. Subsequently, when the sheet P1 passes through the introduction path 211, the second sheet P2 is introduced into the introduction path 211.

  As shown in FIG. 10B, the sheet P1 conveyed through the first branch path 212 is conveyed to the first switchback path 214 by the first reverse roller pair 225 which is driven to rotate normally. On the other hand, the sheet P2 conveyed through the introduction path 211 is guided to the second branch path 213 when the guide flap 223 is positioned so as to close the upstream end of the first branch path 212. The sheet P2 conveyed to the second branch path 213 is conveyed to the second switchback path 215 by the second reversing roller pair 228 which is driven to rotate normally. Subsequently, when the sheet P2 passes through the introduction path 211, the third sheet P3 is introduced into the introduction path 211.

  As shown in FIG. 10C, the sheet P1 that has been conveyed to the downstream side of the first switchback path 214 and is accommodated in the first switchback path 214 is moved by the first reverse roller pair 225 that is driven in the reverse direction to the first reverse roller pair 225. It is conveyed from the downstream side to the upstream side of the 1-switchback route 214, passes through the first merging route 216, and is conveyed to the outlet route 218. On the other hand, the leading edge of the paper sheet P2 conveyed through the second switchback path 215 projects from the opened downstream end of the second switchback path 215, and the bottom surface 215a of the conveyance device side body 201 along the guide portion 215b. Be led up to. Depending on the medium length of the sheet P conveyed in the second switchback path 215 in the conveying direction, it may not be guided to the bottom surface 215a of the conveying device side body 201. Further, the sheet P3 conveyed through the introduction path 211 is guided to the first branch path 212 by the guide flap 223. Subsequently, when the sheet P3 passes through the introduction path 211, the fourth sheet P4 is introduced into the introduction path.

  As shown in FIG. 11A, the paper P2 accommodated in the second switchback path 215 is moved from the downstream side to the upstream side of the second switchback path 215 by the second reverse roller pair 228 which is reversely driven. And then conveyed to the outlet path 218 through the second merging path 217. On the other hand, the sheet P3 conveyed on the first branch path 212 is conveyed to the first switchback path 214.

  As shown in FIG. 11B, the sheet P3 conveyed through the first switchback path 214 is conveyed by the first pair of reversing rollers 225 through the first merging path 216 to the outlet path 218. On the other hand, the sheet P4 conveyed through the introduction path 211 is guided to the second branch path 213 by the guide flap 223 and conveyed to the second switchback path 215.

  That is, the sheets P1, P2, P3, and P4 that are successively conveyed through the introduction path 211 are alternately guided to the first branch path 212 and the second branch path 213 by the guide flap 223. For example, when the first sheet P1 is guided to the second branch path 213, the second sheet P2 is conveyed to the first branch path 212.

  In this way, the paper P recorded by the printer 100 has its posture inverted by the conveying device 200, and is transferred to the post-processing device 300 with the recording surface facing downward in the vertical direction Z during single-sided printing. Is transported. Further, at that time, it is not preferable that the sheet P is curled and conveyed to the post-processing apparatus 300. Therefore, the intermediate conveyance path 210 in the conveyance apparatus side body 201 is curved and meanders. The length of the path in the conveyance direction of the paper P is ensured by forming the path shape that extends.

  That is, it is known that the curl of the sheet P caused by the ink adhering to the recording head 111 of the recording unit 110 gradually subsides with the passage of time. Therefore, the transport device 200 secures the path length of the intermediate transport path 210, so that the sheet P is transported through the intermediate transport path 210 for a time required for the degree of curl generated in the sheet P to be less than or equal to a predetermined value. It is secured as the time required for. After that, the sheet P is subjected to post-processing such as cutting and stapling by the post-processing device 300.

  In particular, since the line head type recording head 111 performs high-speed printing on the paper P and conveys it at high speed, the paper P may be conveyed without being sufficiently dried. That is, the curl may be conveyed to the post-processing apparatus 300 in a state where the curl is not sufficiently set, and the post-processing may not be performed correctly. However, if the conveyance speed in the intermediate conveyance path 210 is reduced to secure the drying time, the paper conveyed at a high speed does not collide with the preceding paper in the intermediate conveyance path 210 during recording. Since the distance is taken, the overall throughput is reduced. In particular, the succeeding paper may collide with the preceding paper while the preceding paper is performing the post-processing.

  Therefore, in the transport device 200, by providing a plurality of switchback routes such as the first switchback route 214 and the second switchback route 215 described above, the size of the interior of the transport device 200 is suppressed while the intermediate transport route 210 of the intermediate transport route 210 is suppressed. A path length can be secured and a drying time can be provided. Further, it is possible not to unnecessarily widen the distance between the sheets even at the time of recording the sheets, and it is possible to achieve both the reduction of the throughput and the reduction of the throughput. Further, as described above, by using a path shape that curves and extends in a meandering manner for the intermediate conveyance path 210, it is possible to further increase the drying time.

According to the above embodiment, the following effects can be obtained.
(1) The movement area when the pull-out unit 170 of the printer 100 is pulled out is configured to avoid the transport device 200 and the post-processing device 300 that form the recording system 1000. Therefore, the medium can be easily removed when the poor conveyance of the paper P in the printer 100 is eliminated.

  (2) When the conveyance failure of the paper P occurs in the discharge path 150 and the branch path 160, the pull-out unit 170 is pulled out from the recording apparatus side body 101, thereby eliminating the conveyance failure of the paper P remaining in the path. However, the paper P may remain in the recording device side body 101 when it is pulled out. Even in such a case, the user can easily take out the paper P from the inside of the recording apparatus side casing 101 by inserting the hand through the opening 105b formed in the recording apparatus side casing 101.

  (3) The first path forming part 171 which is provided in the drawer unit 170 and which forms a part of the curved reversal path 151 a and the second path forming part 172 which forms a part of the branching path 160 rotate around the shaft 173. It is movably installed. Therefore, it is possible to easily eliminate the defective conveyance of the paper P in the curved reversal path 151a and the branch path 160.

  (4) Since the drawer unit 170 is configured to be able to be pulled out to a position where the shaft 173, which is the rotation fulcrum of the first path forming section 171, is exposed from the recording apparatus side body 101, the first path forming section 171 can be opened. It is possible to suppress the risk that the tip of the first path forming portion 171 interferes with the recording device side body 101 when rotating.

  (5) The pull-out unit 170 that is pulled out from the recording-device-side housing 101 is configured so that it can be pulled out from the recording-device-side housing 101 together with the guide mechanism 180 that is provided at the branching position 190 where the poor conveyance of the paper P easily occurs. There is. Therefore, it is possible to easily remove the paper P when the poor conveyance of the paper P in the printer 100 is eliminated.

  (6) When recording is performed on the paper P such as thick paper that has high rigidity and does not require post-processing, the paper P is conveyed to the printer 100 without reversing the posture of the paper P in the vertical direction Z. A second discharge path 152 is provided as a non-inverted discharge path. That is, the thick paper does not need to be transported to the post-processing apparatus 300 via the third discharge path 153 serving as the lower discharge path, and therefore wasteful time is not required when the paper P is transported. Therefore, even when the post-processing apparatus 300 that performs post-processing on the paper P is attached to the printer 100, it is possible to reduce the transport time for the paper P that has high rigidity and does not require post-processing.

  (7) The second discharge path 152 extends linearly along the direction in which the common discharge path 154 extends. Therefore, even when a medium having high rigidity such as thick paper is conveyed, conveyance failure may occur. Can be reduced.

  (8) Since the second discharge path 152 is provided so as to extend above the third discharge path 153 in the vertical direction Z, the discharge tray 109 of the discharge tray 109 from which the paper P conveyed through the second discharge path 152 is discharged. External devices such as the transport device 200 and the post-processing device 300 may be provided below. Therefore, when an external device is attached to the printer 100, it is possible to suppress an increase in the installation area of the entire device when viewed from above in the vertical direction Z.

  (9) By pulling out the drawer unit 170 to which a part of the first discharge path 151 and a part of the branch path 160 are attached from the recording apparatus side body 101, the paper P in the path can be easily taken out. Therefore, it is possible to eliminate the conveyance failure of the paper P that occurs in the first discharge path 151 and the branch path 160.

  (10) Since the paper discharge tray 109 has a sloped rising shape that rises to the upper side in the vertical direction Z toward the downstream side in the transport direction, the paper P already placed is discharged later. It is possible to reduce the risk that the paper P will be pushed out and fall.

  (11) By providing the transport device 200 having the intermediate transport path 210 between the printer 100 and the post-processing device 300, it is possible to increase the transport time for transporting the paper P that requires post-processing. That is, by increasing the transport time of the paper P, it is possible to suppress the degree of curling that occurs on the paper P due to recording by the recording unit 110.

  (12) Since the first switchback route 214 and the second switchback route 215 are curved and extend in a meandering manner, the route lengths of the respective switchback routes 214 and 215 are ensured, but comparison is performed. Since it can be accommodated in a small space, it can contribute to downsizing of the transport device side body 201.

  (13) When viewed from the front-rear direction Y, the paper discharge tray 109 has a portion that overlaps the intermediate conveyance path 210 in the vertical direction, but due to the rising shape, the highest portion of the intermediate conveyance path 210 in the vertical direction Z. It is placed avoiding. Therefore, it is possible to convey the paper P to the post-processing device 300 at a high position while ensuring the raised shape of the paper discharge tray 109. By passing the sheets P to the post-processing device 300 at a high position, the stacking amount of the stacker 302 and the route length of the lead-out route 218 can be secured.

  (14) The transport device 200 has two switchback paths for switching back the paper P in order to improve the processing speed of the paper P introduced from the introduction path 211, that is, the first switchback path 214 and the second switch. And a back path 215. Here, considering that the post-processing device 300 that performs post-processing on the paper P is attached to the transport device 200, it is preferable to lead the paper P to the post-processing device 300 at a high position in the vertical direction Z. For this reason, the lead-out path 218 is configured to extend so as to bypass the downstream end of the first switchback path 214, which may increase the size of the transport device 200 in the vertical direction Z.

  Therefore, the first connection point B where the downstream end of the first branch path 212 and the upstream end of the first switchback path 214 are connected is the downstream end of the second branch path 213 and the upstream end of the second switchback path 215. It is provided so as to be above the second connection point C to which is connected in the vertical direction Z. That is, since the downstream end of the first switchback path 214 is pulled up in the vertical direction Z, even if the lead-out path 218 extends so as to bypass the downstream end of the first switchback path 214, the transport device in the vertical direction Z is formed. The height dimension of 200 can be suppressed. Therefore, it is possible to suppress an increase in size of the apparatus while improving the processing speed of the paper P.

  (15) The first connection point B to which the upstream end of the first switchback path 214 is connected is more vertical than the branch point A that branches from the downstream end of the introduction path 211 into the first branch path 212 and the second branch path 213. Since the first connection point B is located above the branch point A because it is located below in the direction Z, it is possible to reduce the risk of the transport apparatus 200 becoming larger.

  (16) Since the introduction path 211 is provided so as to extend obliquely downward so as to intersect the vertical direction Z, as shown in FIG. 7, the first branch path 212 that branches leftward from the downstream end of the introduction path 211 and the downward direction. It is possible to relatively easily branch to the second branch path 213 that branches into.

  (17) Since the introduction path 211 is provided on the upper side in the vertical direction Z in the transport device side body 201, when providing the first switchback path 214 and the second switchback path 215 extending downward in the vertical direction Z, The introduction path 211 can be formed short. Therefore, it is possible to improve the degree of freedom in the route shape of the intermediate transport route 210 in the transport device-side housing 201.

  (18) Since the downstream portion of the second switchback path 215 includes the guide portion 215b and the bottom surface 215a of the transport device-side housing 201, the cost required for manufacturing can be reduced.

  (19) Since the portion on the downstream side of the second switchback path 215 is configured to include the bottom surface 215a of the transport device side body 201, the second switchback path 215 becomes the first switchback path 214. Similarly, as compared with the configuration that extends downward in the vertical direction Z, it is possible to reduce the possibility that the transport device 200 becomes large.

  (21) The intermediate conveyance path 210 secures a path length by curving so that the entire path meanders. By ensuring the path length, the curl generated on the paper P is kept below a predetermined value while being conveyed through the intermediate conveyance path 210, and the curl can be led out to the post-processing apparatus 300 in a state where the curl is contained. Therefore, the transport device 200 can discharge the paper P while suppressing the degree of curling that occurs on the paper P.

  (22) When the plurality of sheets P are continuously processed in the transport device 200, the two switchback routes, that is, the first switchback route 214 and the second switchback route 215 are provided. The second sheet P2 to be introduced does not need to wait until the preceding first sheet P1 is derived. Therefore, the papers P2, P3, and P4 can be successively derived after the paper P1, so that the processing speed of the paper P can be improved.

The above embodiment may be modified as follows.

The configuration may be arranged on the left side of the branch point A that branches from the downstream end of 211 to the first branch path 212 and the second branch path 213. According to this configuration, as compared with the embodiment shown in FIG. 7, it is possible to reduce the size of the intermediate conveyance route 210 in the left-right direction X and the vertical direction Z while securing the route length of the intermediate conveyance route 210.

In this configuration, the rotation unit 174 rotates about a rotation shaft 175 provided in the recording device side body 101, so that a part of the discharge path 150 is exposed. At this time, since the rotation unit 174 constitutes the guide surface of the guide on the outer side of the curved reversal path 151a included in the first discharge path 151, the inside of the curved reversal path 151a is opened. Further, since the guide mechanism 180 is also attached to the rotating unit 174, it is rotated together with the rotating unit 174 with respect to the recording apparatus side body 101. That is, when the guide mechanism 180 moves together with the rotating unit 174 to the outside of the recording apparatus side body 101, the branch position 190, which is a position where the defective conveyance of the paper P is likely to occur, when viewed from the left in the left-right direction X. It is exposed to. Therefore, the medium can be easily removed when the poor conveyance of the medium in the recording apparatus is eliminated. It should be noted that members that may interfere with each other when the rotating unit 174 rotates are formed in a comb shape so as not to interfere with each other.
