Then, the post-processed paper P is placed on a stacker (two in the present embodiment) 302 that extends 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 from the upper side in the vertical direction Z with respect to the paper P, and the paper P is transported along the transport path 120 in the recording apparatus side housing 101 of the printer 100. And a transporting unit 130 to be provided. The transport path 120 is formed such that the paper P is transported with the direction intersecting the width direction as the transport direction when the direction along the front-rear direction Y is the width direction of the paper (medium) P.

  The recording unit 110 includes a line head type recording head 111 that can simultaneously eject ink over substantially the entire width direction of the paper P. 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 conveyance unit 130 includes a plurality of conveyance roller pairs 131 arranged along the conveyance path 120 and a belt conveyance unit 132 provided immediately below the recording unit 110. In other words, ink is ejected from the recording head 111 onto the paper P being conveyed by the belt conveyance unit 132, and recording is performed.

  The belt conveyance unit 132 includes a driving roller 133 disposed upstream of the recording head 111 in the conveyance direction, a driven roller 134 disposed downstream of the recording head 111 in the conveyance direction, and each of these rollers 133. And an endless belt 135 hung on 134. When the driving roller 133 is driven and rotated, the belt 135 circulates, and the paper P is conveyed to the downstream side by the circulated belt 135. That is, the outer peripheral surface of the belt 135 functions as a support 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 paper P that has been recorded and recorded by the recording unit 110 is transported, and a discharge path 150. And a branching path 160 branching from.

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

  In the second supply path 142, in the vertical direction Z, the paper P accommodated in the paper cassette 103 provided at the lower part of the recording apparatus side housing 101 is conveyed to the recording unit 110. That is, the paper P stored in the paper cassette 103 in a stacked state is reversed in posture in the vertical direction Z after the uppermost paper P is fed out by the pickup roller 142a and separated one by one by the separation roller pair 145. However, 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 on which one side has been recorded by the recording unit 110 is conveyed again to the recording unit 110. That is, a branch path 160 that branches from the discharge path 150 is provided downstream of the recording unit 110 in the transport direction. That is, when performing duplex printing, the paper P is conveyed to the branch path 160 by the operation of the branch mechanism 147 provided in the middle of the discharge path 150. Further, the branch path 160 is provided with a branch path roller pair 161 capable of both normal rotation and reverse rotation on the downstream side of the branch mechanism 147.

  At the time of duplex printing, the paper P on which one side is printed is once guided to the branch path 160 by the branch mechanism 147 and conveyed downstream in the branch path 160 by the branch path roller pair 161 rotating in the forward direction. Thereafter, the sheet P conveyed to the branch path 160 is reversely transported from the downstream side to the upstream side in the branch path 160 by the branch path roller pair 161 that is reversed. That is, the transport direction of the paper P transported through the branch path 160 is reversed.

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

  Among the supply paths 141, 142, and 143, the second supply path 142 and the third supply path 143 convey the paper P toward the recording unit 110 while the posture of the paper P is curved in the vertical direction Z. On the other hand, compared to the second supply path 142 and the third supply path 143, the first supply path 141 transports the sheet P toward the recording unit 110 without significantly curving the posture of the sheet P. .

  The sheet P conveyed through the supply paths 141, 142, and 143 is conveyed to the alignment roller pair 149 disposed upstream of the recording unit 110 in the conveyance direction, and then is transferred to the alignment roller pair 149 that has stopped rotating. Its tip hits. And the inclination with respect to a conveyance direction is correct | amended (skew removal) by the state which the paper P contact | abutted to such an alignment roller pair 149. FIG. Then, the sheet P whose inclination is corrected is aligned and conveyed to the recording unit 110 by the subsequent rotational driving of the alignment roller pair 149.

  The recording unit 110 performs recording on one side or both sides, and the sheet P on which recording is completed is transported along a discharge path 150 that forms a downstream part of the transport path 120 by a transport roller pair 131. The discharge path 150 is branched into a first discharge path 151, a second discharge path 152, and a third discharge path 153 at a position downstream of the position branched from the branch path 160. In other words, the sheet P for which recording has been completed is transported through a common discharge path (upstream discharge path) 154 that constitutes an upstream portion of the discharge path 150, and then a guide mechanism (switching) provided at the downstream end of the common discharge path 154. The guide part) 180 guides to any one of the first to third discharge paths (downstream discharge paths) 151, 152, and 153 constituting the downstream part of the discharge path 150.

  The first discharge path (upper discharge path) 151 is provided so as to extend upward of the recording apparatus side housing 101 and bend along the branch path 160. The sheet 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 housing 101 so as to be the end of the first discharge path 151. The paper P discharged from the discharge port 155 falls downward in the vertical direction Z, and is discharged onto the mounting table 156 in a stacked state as indicated by a two-dot chain line in FIG. The paper P is discharged from the discharge port 155 to the mounting table 156 in a posture in which the recording surface in single-sided printing faces downward in the vertical direction Z by the conveyance roller pairs 131 arranged at a plurality of locations in the discharge path 150. The

  The mounting table 156 has an upwardly inclined shape that rises upward in the vertical direction Z as it goes to the right in the left-right direction X, and the sheets P are stacked on the mounting table 156. At this time, each sheet P placed on the placement table 156 moves to the left along the inclination of the placement table 156, and the vertical side wall 157 provided below the discharge port 155 of the recording apparatus side housing 101. Placed close to.

  The first discharge path 151 has a curved inversion 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 curve reversal path 151a is curved with the recording surface of the paper P recorded by the recording unit 110 facing inward, and the recording surface of the paper P is directed upward in the vertical direction Z in the vertical direction Z from the vertical direction Z. The paper P is reversed so that it faces downward. Therefore, in the discharge path 150, the paper P passes through the curved inversion path 151 a and is discharged from the discharge port 155 so that the recording surface at the time of single-sided printing faces the mounting table 156.

  The second discharge path 152 branches below the first discharge path 151 in the vertical direction Z, and extends linearly from the recording unit 110 toward the lead-out surface part 106 that forms a part of the recording apparatus side housing 101. Yes. Therefore, the sheet P conveyed through the second discharge path 152 is not conveyed in a curved posture as in the first discharge path 151, and the posture is kept constant as when passing through the recording unit 110. The sheet is conveyed linearly and discharged from a discharge port 108 formed in the drawing surface portion 106 to a discharge tray 109 attached to the drawing surface portion 106. That is, the second discharge path 152 functions as a non-reverse discharge path for transporting the paper P toward the paper discharge tray 109 without reversing the posture of the paper P in the vertical direction.

  The third discharge path (downward discharge path) 153 branches downward in the vertical direction Z with respect to the second discharge path 152 and heads obliquely downward in the vertical direction Z so as to go downward of the recording apparatus side housing 101. It extends. The downstream end is connected to the upstream end of the introduction path 211 of the transport apparatus 200 in the recording apparatus side casing 101. That is, the paper P conveyed through the third discharge path 153 is discharged to the conveyance 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 apparatus side housing 101. The drawer unit 170 is connected to the drawer surface unit 106 so as to be integrally handled. Therefore, the drawer unit 170 is pulled out from the recording apparatus side housing 101 when the drawer surface portion 106 is pulled out, and is exposed from the recording apparatus side housing 101.

  The drawer unit 170 includes a first path forming portion 171 constituting 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 constituting a part of the curved inner guide surface is attached so as to be rotatable about a shaft 173 provided in the drawer unit 170. That is, in the state where the drawer unit 170 is pulled out, the path forming portions 171 and 172 rotate in the clockwise direction in FIG. 3 about the shaft 173, so that the inside of the branch path 160 and the first discharge path 151 is exposed. (See FIGS. 8 and 9).

  As shown in FIGS. 4 to 6, the guide mechanism 180 includes a first guide part 181 and a second guide part 182. Each guide unit 181, 182 is provided at a branching position 190 that branches from the downstream end of the common discharge path 154 to each of the first to third discharge paths 151, 152, 153, and the conveyance direction of the paper P from the recording unit 110 In the left-right direction X, the first guide portion 181 is shifted and the second guide portion 182 is positioned on the left side on the downstream side. Also in the vertical direction Z, the first guide portion 181 and the second guide portion 182 are arranged so as to be shifted so as to be located on the lower side and the second guide portion 182 on the upper side.

  In addition, the guide portions 181 and 182 have 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 transport direction, respectively. It is provided at the center so as to be rotatable. Each of the guide portions 181 and 182 is a portion on the right side on the upstream side in the left-right direction X that is the transport direction by rotating about the shafts 185 and 186 that each has, and the base end portions 183 and 184 The positions of the tip portions 187 and 188 on the opposite side are displaced vertically in the vertical direction Z. In other words, the guide portions 181 and 182 are separated from the first path forming portion 171 and the upper position where the respective leading end portions 187 and 188 positioned 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. Incidentally, 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 guide portions 181 and 182 is selectively switched to the upper position or the lower position, and comes into contact with the paper P being conveyed through the common discharge path 154, whereby the paper P is moved from the first to the third. To one of the discharge paths 151, 152, and 153. Incidentally, the guide portions 181 and 182 are formed in, for example, comb teeth from the base end portions 183 and 184 to the tip end portions 187 and 188 so as not to interfere with each other's rotation operation so that they do not interfere with each other. It is configured. Note that this rotation operation in each of the guide units 181 and 182 is controlled by a control unit (not shown) included in the printer 100.

  FIG. 4 is a view when both the front end portion 187 of the first guide portion 181 and the front end portion 188 of the second guide portion 182 are located at the lower position. At this time, the front end 187 of the first guide 181 is positioned so as to block the upstream end of the third discharge path 153, and the front end 188 of the second guide 182 closes the upstream end of the second discharge path 152. Is located. That is, in the state of FIG. 4, the guide mechanism 180 guides the paper P conveyed through the common discharge path 154 to the first discharge path 151.

  FIG. 5 is a view when the distal end portion 187 of the first guide portion 181 is located at the lower position and the distal end portion 188 of the second guide portion 182 is located at the upper position. At this time, the front end 187 of the first guide 181 is positioned so as to block the upstream end of the third discharge path 153, and the front end 188 of the second guide 182 closes the upstream end of the first discharge path 151.

At this time, the tip 187 of the first guide 181 is positioned so as to block the upstream end of the first discharge path 151 and the upstream end of the second discharge path 152, and the tip 188 of the second guide 182 is It is located so as to block the upstream end of one discharge path 151. That is, in the state of FIG. 6, the guide mechanism 180 guides the paper P conveyed through the common discharge path 154 to the third discharge path 153.

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

  The intermediate conveyance unit 220 includes a plurality of intermediate conveyance roller pairs 221 provided along the intermediate conveyance path 210. In other words, the sheet P is conveyed along the intermediate conveyance path 210 when the pair of intermediate conveyance rollers 221 is rotationally driven in a state where the sheet P is sandwiched and supported from both the front and back sides.

  The intermediate transport 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 introduces the paper P into the transport apparatus-side casing 201 at the upstream end thereof. The introduction path 211 is provided at an upper position in the vertical direction Z in the introduction unit 202, and extends vertically from the inside of the recording apparatus side casing 101 on the upstream side in the transport direction to the inside of the transport apparatus side casing 201 on the downstream side. It extends straight down and crosses Z. That is, the introduction path 211 is provided so as to penetrate a part of the side wall constituting the left side surface of the recording apparatus side casing 101 and a part of the side wall constituting the right side face of the transport apparatus side casing 201. In addition, a sensor 222 that detects the paper P that is transported through the introduction path 211 is provided in a downstream portion of the introduction path 211 that is located in the transport apparatus-side casing 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 (leftward in FIG. 7) from the downstream end of the introduction path 211, and extends so as to curve downward in the middle. The second branch path 213 branches while curving further downward (rightward in FIG. 7) from the downstream end of the introduction path 211, and thereafter extends downward so as to meander. That is, the intermediate conveyance path 210 branches from the branch point A, which is the downstream end of the introduction path 211, to the first branch path 212 and the second branch path 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 unit) 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 on the introduction path 211 to the first branch path 212. The position is switched between the position to be guided to the branch path 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 transport direction is configured to be longer than the medium length in the transport direction of the paper P that can be recorded by the printer 100.

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

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

  On the other hand, as shown in FIG. 7, the upstream end of the second switchback path 215 is connected to the downstream end of the second branch path 213. The second switchback path 215 is provided so as to curve downward 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 opened toward the right inner surface of the transport apparatus side body 201. A guide portion 215b that curves and extends from the right inner surface of the transport apparatus side housing 201 to the bottom surface 215a of the transport apparatus housing 201 is provided at a position facing the downstream end. That is, when the paper P is transported through the second switchback path 215, the leading edge of the paper P protrudes from the opened downstream end, and the leading edge of the protruding paper P is guided by the guide portion 215b. It is guided so as to sink into the bottom surface 215a of the body 201 below the downstream end of the first switchback path 214.

  That is, the second switchback path 215 includes the guide portion 215b and the bottom surface 215a of the transfer device side housing 201. Further, the path length of the second switchback path 215 in the transport direction is configured to be equal to or longer than the medium length in the transport direction of the paper P that can be printed by the printer 100, as in the case of the first switchback path 214. Yes. Of course, the downstream part of the second switchback path 215 configured by the guide part 215b and the bottom surface 215a of the transport apparatus side body 201 may be the same as the upstream part or only the guide part 215b. It may be.

  In the upstream portion of the second switchback path 215, one sensor 227 that detects the paper P conveyed on the second switchback path 215 is positioned upstream of the curved portion, and the forward rotation direction and the reverse rotation. A pair of second reversing rollers 228 that can rotate in the direction is provided. Further, another pair of the second reversing roller pair 228 is provided at a position downstream of the curved portion in the upstream portion of the second switchback path 215. Two pairs of second reversing roller pairs 228 are provided to perform forward rotation driving or reverse rotation driving based on a 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 reverse roller pair 228.

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

  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 junction path 216 extends while curving in the right and left 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. . Further, the upstream end of the second junction path 217 is connected to the upstream end of the second switchback path 215. That is, the second junction path 217 extends in the left-right direction X while curving leftward 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. . Then, the first merge path 216 and the second merge path 217 are merged at the merge point D located between the first switchback path 214 and the second switchback path 215.

  In other words, when the paper P is transported 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 when the front end of the paper P comes into contact. Is displaced as follows. On the other hand, when the paper P is reversely conveyed (switched back) from the first switchback path 214, the conveyance of the paper P to the first branch path 212 is restricted by the first restriction flap 226, and the paper P is joined to the first joining path 212. Guided to route 216. Further, when the paper P is transported from the second branch path 213 to the second switchback path 215, the second regulating flap 229 opens the downstream end of the second branch path 213 by contacting the front end of the paper P. Is displaced as follows. On the other hand, when the paper P is reversely transported (switched back) from the second switchback path 215, the transport of the paper P to the second branch path 213 is restricted by the second restriction flap 229, and the paper P is joined to the second joining path 215. Guided to route 217.

  The upstream end of the derivation path 218 is connected to the junction point D where the downstream end of the first junction path 216 and the downstream end of the second junction path 217 are connected. The lead-out path 218 extends downward while bending so as to pass between the first switchback path 214 and the second switchback path 215 toward the post-processing device 300, and then the downstream end of the first switchback path 214 It detours to wrap around the lower side and extends to the upper part of the lead-out part 203. The downstream end of the lead-out path 218 passes through a part of the left side wall of the transport apparatus side housing 201 and extends toward the post-processing apparatus 300. That is, the intermediate transport path 210 includes the introduction path 211, the first branch path 212, the second branch path 213, the first switchback path 214, the second switchback path 215, the first merge path 216, the second merge path 217, and the like. A derivation path 218 is provided. Further, the positional relationship between 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 length. The path lengths of the first merge path 216 and the second merge path 217 are also substantially the same length.

  Next, the operation when the conveyance failure of the paper P in the recording system 1000 configured to include the printer 100 and the printer 100 and the conveyance device 200 is eliminated will be described.

  In a recording apparatus that records and conveys on a sheet-like medium such as paper P like the printer 100 shown in FIG. 3, a conveyance failure such as a paper jam occurs while the paper P is being conveyed along the path. May occur. In particular, in a recording apparatus that performs recording by discharging a liquid such as ink onto a medium, the recording surface of the paper P expands, and a curl that makes the recording surface convex is more likely to occur than in the recording unit 110. A conveyance failure is likely to occur on the downstream side. Accordingly, the printer 100 according to the present embodiment can pull out a part of the discharge path 150 and a part of the branch path 160 from the recording apparatus-side casing 101 in order to make it easy to take out the paper P that is jammed during such conveyance. It has a simple structure.

  As shown in FIG. 8, when the paper P is jammed in the discharge path 150 and the branch path 160, the user first removes the paper discharge tray 109 attached to the drawer surface portion 106 and then the user removes the drawer surface portion 106. The hand-drawn portion 107 is held and the pull-out surface portion 106 is pulled out along the pull-out direction that is the left direction in the left-right direction X that is the conveyance direction of the paper P. 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 housing 101 together with the pull-out surface portion 106. That is, a part of the curved inversion path 151a, the second discharge path 152, the third discharge path 153, and the branch path 160 constituting the discharge path 150 is drawn out. Further, the guide mechanism 180 provided at the branch position 190 that is the downstream end of the common discharge path 154 is also pulled out of the recording apparatus side housing 101.

  At this time, since the height of the introduction part 202 constituting the conveyance device 200 attached to the left side of the printer 100 is formed to be lower than the lower part of the drawer surface part 106, the drawer unit 170 is pulled out from the introduction part 202. Does not interfere with the drawer surface portion 106 and the drawer unit 170. The introduction unit 202 has a length in the left-right direction X that is longer than a region (movement region) in which the drawer unit 170 moves in the left-right direction X, that is, a length in which the drawer unit 170 is pulled out from the recording apparatus side housing 101. It is formed to become. Therefore, the lead-out part 203 formed so as to be higher than the introduction part 202 does not interfere with the drawer surface part 106 and the drawer unit 170 when the drawer unit 170 is pulled out. In other words, the transport apparatus 200 is formed so as to avoid a movement area when the drawer unit 170 is pulled out from the recording apparatus side casing 101. If the drawer unit 170 is configured to be able to be pulled out in a direction that intersects the conveyance direction of the paper P, when the drawer unit 170 is pulled out, the paper P in which a paper jam has occurred may be broken in the path. Therefore, it is preferable that the drawer unit 170 has a configuration that allows the drawer unit 170 to be pulled out in the direction along the conveyance direction of the paper P.

  As shown in FIG. 9, after the drawer unit 170 is pulled out from the recording apparatus side housing 101, the first path forming unit 171 and the second path forming unit 172 attached to the drawer unit 170 are watched around the shaft 173. Turn in the turning direction. Then, the inner guide surface of the curved reversing path 151a constituting 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. When the outer guide surface and the inner guide surface of the curved reversing path 151a and the branch path 160 are separated from each other, the path is opened, and the paper P in which a paper jam has occurred in the path can be taken out. Further, when the drawer unit 170 is pulled out, the paper P may remain in the recording apparatus side housing 101 instead of the drawer 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. Note that the opening 105b formed in the frame 105 of the printer 100 is at a position at least partially overlapping the drawer unit 170 when viewed from the front-rear direction Y in a state where the drawer unit 170 is not pulled out from the recording apparatus side housing 101. Is formed.

Next, an operation when the printer 100 performs recording 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 stored 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. The Since a medium such as cardboard is difficult to bend due to its high rigidity, if it is conveyed along the conveyance path 120 having a large degree of curvature, it may cause a conveyance failure such as a paper jam. Therefore, the first supply path 141 is a straight path that has a smaller degree of curvature than the second supply path 142 and extends straight toward the recording unit 110.

  The cardboard that has been 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 constitute the discharge path 150. Here, if the recorded cardboard is to be placed on the placement table 156, the first discharge path 151 is conveyed. However, since the first discharge path 151 has a curved reversal path 151a that is largely curved, there is a possibility that a conveyance failure may occur when thick paper is conveyed. Further, when the thick paper is to be placed on the stacker 302 included in the post-processing apparatus 300 from the third discharge path 153 via the transport apparatus 200, the transport apparatus 200 needs to be provided with a path with a small degree of curvature. There is a risk that the degree of freedom in designing the intermediate transport path 210 of the 200 may be reduced.

  Therefore, the printer 100 of the present embodiment is provided with a second discharge path 152 formed so as to extend straight along the common discharge path 154. In other words, the thick paper that passes through the recording unit 110 from the second supply path 142 and is transported through the common discharge path 154 and the second discharge path 152 always has one surface on the upper side in the vertical direction Z when inserted into the insertion port 141b. It is transported while facing upward. Then, the recording surface is discharged from the discharge port 108 with one surface facing upward and placed on the discharge tray 109.

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

  As shown in FIG. 10A, the first sheet P <b> 1 that is introduced into the conveyance apparatus side housing 201 is conveyed downstream along the introduction path 211. Then, the sheet flap P 223 provided at the downstream end of the introduction path 211 is positioned so as to block the upstream end of the second branch path 213, whereby the paper P 1 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 paper P1 conveyed on the first branch path 212 is conveyed to the first switchback path 214 by the first reverse roller pair 225 that is driven to rotate forward. On the other hand, the sheet P <b> 2 conveyed through the introduction path 211 is guided to the second branch path 213 by positioning the guide flap 223 so as to block 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 reverse roller pair 228 that is driven to rotate forward. 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. 10 (c), the paper P1 conveyed downstream in the first switchback path 214 and stored in the first switchback path 214 is moved by the first reverse roller pair 225 to be driven in reverse. The first switchback path 214 is transported from the downstream side toward the upstream side, is transported to the lead-out path 218 through the first junction path 216. On the other hand, the front end of the sheet P2 conveyed through the second switchback path 215 protrudes from the opened downstream end of the second switchback path 215, and the bottom surface 215a of the conveyance apparatus side casing 201 is along the guide portion 215b. Led up to. Depending on the medium length in the transport direction of the paper P transported through the second switchback path 215, the paper may not be guided to the bottom surface 215a of the transport device side casing 201. Further, the sheet P3 conveyed along 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 stored 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 that is driven to rotate backward. And is conveyed through the second merging path 217 to the outlet path 218. On the other hand, the sheet P3 conveyed through 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 reverse roller pair 225 through the first merge 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 is conveyed to the second switchback path 215.

  That is, the sheets P 1, P 2, P 3, and P 4 conveyed one after the other along 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 on which recording has been performed by the printer 100 is reversed in posture by the transport device 200, and the recording surface at the time of single-sided printing faces the lower side in the vertical direction Z to the post-processing device 300. It is conveyed. At this time, it is not preferable that the paper P is conveyed to the post-processing apparatus 300 in a state where the paper P is curled. Therefore, the intermediate conveyance path 210 is curved and meanders in the conveyance apparatus-side casing 201. By adopting the extended path shape, the path length in the transport direction of the paper P is secured.

  That is, it is known that the curl of the paper P caused by the ink being attached to the recording head 111 included in the recording unit 110 gradually settles with time. For this reason, the transport apparatus 200 secures the length of the intermediate transport path 210 so that the paper P is transported through the intermediate transport path 210 for the time required for the degree of curl generated on the paper P to become a predetermined level or less. The time required for Thereafter, the paper 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 transports it at high speed, the paper P may be transported without being sufficiently dried. That is, the curl may be conveyed to the post-processing apparatus 300 in a state where the curl does not sufficiently fit, and post-processing may not be performed correctly. However, if the transport speed in the intermediate transport path 210 is reduced to ensure the drying time, the sheet transported at a high speed during recording does not collide with the preceding paper in the intermediate transport path 210. The overall throughput is reduced due to the distance. In particular, there is a possibility that the succeeding sheet collides with the preceding sheet while the preceding sheet is performing the post-processing.

  Therefore, in the transport apparatus 200, by providing a plurality of switchback paths such as the first switchback path 214 and the second switchback path 215 described above, the size of the intermediate transport path 210 can be reduced while suppressing an increase in the size of the transport apparatus 200. It is possible to secure a path length and provide a drying time. Further, it is possible to satisfy both the need not to unnecessarily increase the distance between sheets even during recording of sheets and not to reduce the throughput. Further, as described above, by using a path shape that is curved 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 moving area when the drawer unit 170 included in the printer 100 is pulled out is configured to avoid the conveyance device 200 and the post-processing device 300 that constitute the recording system 1000. Therefore, the medium can be easily removed when the conveyance failure of the paper P in the printer 100 is eliminated.

  (2) When a conveyance failure of the paper P occurs in the discharge path 150 and the branch path 160, the conveyance failure of the paper P remaining in the path is solved by pulling out the drawer unit 170 from the recording apparatus side housing 101. However, the paper P may remain in the recording apparatus side housing 101 when it is pulled out. Even in such a case, the paper P can be easily taken out from the recording apparatus side housing 101 by inserting a hand from the opening 105 b formed in the recording apparatus side housing 101.

  (3) A first path forming unit 171 that forms part of the curved inversion path 151 a and a second path forming unit 172 that forms part of the branch path 160 provided in the drawer unit 170 rotate around the shaft 173. It is provided to be movable. Therefore, the conveyance failure of the paper P in the curved inversion path 151a and the branch path 160 can be easily eliminated.

  (4) Since the drawer unit 170 is configured to be able to be pulled out to the position where the shaft 173 that is the rotation fulcrum of the first path forming unit 171 is exposed from the recording apparatus side housing 101, the first path forming unit 171 is removed. When rotating, the possibility that the tip of the first path forming portion 171 interferes with the recording apparatus side housing 101 can be suppressed.

  (5) The drawer unit 170 pulled out from the recording apparatus side housing 101 is configured to be able to be pulled out from the recording apparatus side housing 101 together with the guide mechanism 180 provided at the branch position 190 where the conveyance failure of the paper P is likely to occur. Yes. Therefore, when the conveyance failure of the paper P in the printer 100 is eliminated, the paper P can be easily removed.

  (6) When recording is performed on a paper P that has high rigidity and does not require post-processing like a thick paper, 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-reverse discharge path. In other words, the cardboard does not need to be transported toward the post-processing apparatus 300 via the third discharge path 153 serving as a lower discharge path, and therefore, wasteful time is not required when transporting the paper P. Therefore, even when the post-processing apparatus 300 that performs post-processing on the paper P is attached to the printer 100, the conveyance time can be shortened for the paper P that has high rigidity and does not require post-processing.

  (7) Since the second discharge path 152 extends linearly along the direction in which the common discharge path 154 extends, a conveyance failure may occur even when a medium having a large rigidity such as cardboard is conveyed. 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 second discharge path 152 of the discharge tray 109 on which the sheet P conveyed through the second discharge path 152 is discharged. An external device such as the transfer device 200 or the post-processing device 300 can be provided below. Therefore, when an external device is attached to the printer 100, an increase in the installation area of the entire device can be suppressed when viewed from the upper side 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 housing 101, the paper P in the path can be easily taken out. Accordingly, 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 an upwardly inclined shape that rises upward in the vertical direction Z toward the downstream side in the transport direction, the already loaded paper P is discharged later. It is possible to reduce the possibility of the paper P being pushed out and falling.

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

  (12) Since the first switchback path 214 and the second switchback path 215 are curved and extend so as to meander, comparison is made while ensuring the path length of each switchback path 214, 215. Therefore, it can be accommodated in a small space, and can contribute to the miniaturization of the transport apparatus side housing 201.

  (13) When viewed from the front-rear direction Y, the discharge tray 109 has a portion that overlaps the intermediate conveyance path 210 in the vertical direction, but is the highest part of the intermediate conveyance path 210 in the vertical direction Z due to the rising shape. Arranged to avoid. Therefore, it is possible to transport the paper P to the post-processing apparatus 300 at a high position while ensuring the rising shape of the paper discharge tray 109. By delivering the paper P at a high position to the post-processing device 300, it is possible to secure the stacking amount of the stacker 302 and the route length of the derivation route 218.

  (14) In order to improve the processing speed of the paper P introduced from the introduction path 211, the transport device 200 has two switchback paths for switching back the paper P, 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 extends so as to bypass the downstream end of the first switchback path 214, so that the size of the transport device 200 may increase 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. And the second connection point C to be connected to each other 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, the conveying device in the vertical direction Z even if the derivation path 218 extends so as to bypass the downstream end of the first switchback path 214. The height dimension of 200 can be suppressed. Therefore, it is possible to suppress the enlargement 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 perpendicular to the branch point A that branches from the downstream end of the introduction path 211 to the first branch path 212 and the second branch path 213. Since it is located below in the direction Z, it is possible to reduce the possibility that the size of the transport device 200 increases when the first connection point B is located above the branch point A.

  (16) Since the introduction path 211 is provided to extend obliquely downward intersecting the vertical direction Z, as shown in FIG. 7, the first branch path 212 and the downward direction branch from the downstream end of the introduction path 211 to the left. The second branch path 213 can be branched relatively easily.

  (17) Since the introduction path 211 is provided on the upper side in the vertical direction Z in the transport apparatus side body 201, the first switchback path 214 and the second switchback path 215 extending downward in the vertical direction Z are provided. The introduction path 211 can be formed short. Accordingly, the degree of freedom of the path shape of the intermediate transport path 210 in the transport apparatus side housing 201 can be improved.

  (18) Since the downstream portion of the second switchback path 215 is composed of the guide portion 215b and the bottom surface 215a of the transfer device side casing 201, the cost required for manufacturing can be reduced.

  (19) The portion on the downstream side of the second switchback path 215 is configured to include the bottom surface 215a of the transport apparatus side housing 201, so that the second switchback path 215 is connected to the first switchback path 214. Similarly, compared with a configuration that extends downward in the vertical direction Z, it is possible to reduce the possibility that the transport device 200 is increased in size.

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

  (22) When a plurality of sheets P are continuously processed in the transport apparatus 200, two switchback paths, the first switchback path 214 and the second switchback path 215, are provided. The introduced second sheet P2 does not need to wait until the preceding first sheet P1 is derived. Therefore, since the paper P2, P3, and P4 can be derived one after another after the paper P1, the processing speed of the paper P can be improved.

In addition, you may change the said embodiment as follows.
In the above embodiment, as shown in FIG. 12, 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 is an introduction path in the left-right direction X.

In this configuration, the rotation unit 174 rotates about a rotation shaft 175 provided in the recording apparatus side housing 101, so that a part of the discharge path 150 is exposed. At this time, since the rotation unit 174 constitutes a guide surface of the guide outside the curve reversing path 151a included in the first discharge path 151, the inside of the curve reversing path 151a is opened. Further, since the guide mechanism 180 is also attached to the rotation unit 174, the guide mechanism 180 is rotated with respect to the recording apparatus side housing 101 together with the rotation unit 174. In other words, when the guide mechanism 180 moves together with the rotation unit 174 to the outside of the recording apparatus side housing 101, the branch position 190, which is a position where poor conveyance of the paper P is likely to occur, is viewed from the left in the left-right direction X. To be exposed. Therefore, it is possible to easily remove the medium when eliminating the conveyance failure of the medium in the recording apparatus.
