  The guide member 25 guides the paper conveyed from at least one of the first carry-in path 21a and the second carry-in path 23a to at least one of the first discharge path 21b and the second discharge path 23b.

  Specifically, the guide member 25 includes a first guide member 251, a second guide member 252, and a third guide member 253. The first guide member 251 is a member that guides the sheet from the first carry-in path 21a to one of the first discharge path 21b and the second discharge path 23b. The second guide member 252 is a member that guides the sheet from the second carry-in path 23a to one of the first discharge path 21b and the second discharge path 23b. The third guide member 253 is a member that guides a sheet guided by one of the first guide member 251 and the second guide member 252.

  More specifically, the first guide member 251 includes a first movable guide member 251a and a first fixed guide member 251b. The first movable guide member 251a is disposed along the first carry-in path 21a, and can change the direction of the paper conveyed from the first carry-in path 21a. The first movable guide member 251a is formed in, for example, a comb shape. The first fixed guide member 251b movably supports the downstream side of the first movable guide member 251a. The first fixed guide member 251b guides the paper along the direction of the paper guided by the first movable guide member 251a.

  The second guide member 252 includes a second movable guide member 252a and a second fixed guide member 252b. The second movable guide member 252a is arranged along the second carry-in path 23a, and can change the direction of the paper conveyed from the second carry-in path 23a. The second movable guide member 252a is formed in, for example, a comb shape. The second fixed guide member 252b movably supports the downstream side of the second movable guide member 252a. The second fixed guide member 252b guides the paper along the direction of the paper guided by the second movable guide member 252a.

  The third guide member 253 includes a third movable guide member 253a and a third fixed guide member 253b. The third movable guide member 253a is disposed at a position facing each of the first fixed guide member 251b and the second fixed guide member 252b. The third movable guide member 253a is interlocked with at least one of the first movable guide member 251a and the second movable guide member 252a.

  When the sheet is guided toward the first discharge path 21b by the first guide member 251, the third movable guide member 253a corrects the direction in which the sheet is guided toward the first discharge path 21b. When the second guide member 252 guides the sheet toward the second discharge path 23b, the third movable guide member 253a corrects the direction in which the sheet is guided toward the second discharge path 23b.

  The third fixed guide member 253b is disposed at a position facing each of the first fixed guide member 251b and the second fixed guide member 252b via the third movable guide member 253a. The third fixed guide member 253b guides the paper transported along the third movable guide member 253a.

  Specifically, the third movable guide member 253 a includes a first surface 254 and a second surface 255. The second surface 255 has an obtuse angle with the first surface 254 and is a surface formed by extending the first surface 254.

  When the sheet is guided in a direction toward the first discharge path 21b or the second discharge path 23b, the third movable guide member 253a is a direction in which the sheet is guided out of the first surface 254 and the second surface 255. Of the first surface 254 and the second surface 255, the downstream surface of the first surface 254 and the second surface 255 in the direction in which the paper is guided is corrected. The position is corrected to a position along the sheet conveyance direction.

  For example, in the example of FIG. 2, a case where the paper is guided in the direction toward the first discharge path 21b will be described. In this case, of the first surface 254 and the second surface 255, the upstream surface in the direction in which the sheet is guided becomes the second surface 255. On the other hand, of the first surface 254 and the second surface 255, the downstream surface in the direction in which the sheet is guided becomes the first surface 254. Therefore, the second surface 255 is corrected to a position separated from the direction in which the sheet is guided by the first angle B. The first surface 254 is corrected to a position along the direction in which the sheet is guided.

  Further, for example, in the example of FIG. 3, a case where the paper is guided in a direction toward the second discharge path 23b will be described. In this case, of the first surface 254 and the second surface 255, the upstream surface in the direction in which the sheet is guided becomes the first surface 254. On the other hand, of the first surface 254 and the second surface 255, the downstream surface in the direction in which the sheet is guided is the second surface 255. Therefore, the first surface 254 is corrected to a position away from the direction in which the sheet is guided by the first angle B. The second surface 255 is corrected to a position along the direction in which the sheet is guided.

  In addition, since the 1st surface 254 and the 2nd surface 255 are integrally formed, if the position of any one of the 1st surface 254 and the 2nd surface 255 is corrected, the 1st surface 254 and the 2nd surface One of the other positions of 255 is corrected.

  The first fixed guide member 251b includes a first facing surface 257 that faces the third movable guide member 253a. As shown in FIG. 3, the first facing surface 257 is disposed at a position away from the second path 23 by the second angle C. The second fixed guide member 252b includes a second facing surface 258 that faces the third movable guide member 253a. As shown in FIG. 2, the second facing surface 258 is disposed at a position away from the first path 21 by the second angle C.

  The first angle B is, for example, 25 °, and the second angle C is, for example, 20 °. That is, it is preferable to keep the angle of the place where the paper is introduced at 20 to 25 °.

  Next, this embodiment is compared with a conventional example. FIG. 7 is a diagram illustrating an example of the overall configuration of a conventional paper transport device 1 ′. As shown in FIG. 7, in the conventional sheet conveying apparatus 1 ′, the auxiliary path 22 ′ where the decurler 33 ′ is arranged is connected to the second path 23 ′ by arranging the outlet path 24 ′. Yes. Also between the first path 21 ′ and the second path 23 ′, a plurality of output destinations are formed by arranging the outlet path 24 ′. The exit path 24 ′ is preferably formed with a constant curvature in order to stabilize the sheet transportability. Since the exit path 24 ′ formed with a constant curvature requires a certain space, the machine width of the sheet conveying apparatus 1 ′ is increased by the exit path 24 ′. Further, in order to realize a plurality of output destinations by the exit path 24 ′, a guide structure capable of selectively branching the path is further required, so that the path configuration is complicated.

  Therefore, in the present embodiment, the sheet transport apparatus 1 includes a first path 21 and a second path 23 that intersects the first path 21 at the intersection A. That is, by intersecting two routes at one intersection A, a certain space required for a route such as the exit route 24 'formed with a certain curvature for each output destination can be suppressed.

  In the present embodiment, the guide member 25 is disposed at the intersection A. The guide member 25 can connect the downstream side of the first carry-in path 21a and the second carry-in path 23a and the upstream side of the first discharge path 21b and the second discharge path 23b with a simple configuration.

  Therefore, the arrangement of the outlet path 24 ′ formed with a constant curvature as shown in FIG. 7 is suppressed, and the conveyance source and the conveyance destination are connected by a simple guide structure. Therefore, the conveyance path can be stabilized while suppressing the machine width of the entire apparatus.

  In the present embodiment, the output destination of the sheet is guided by the first guide member 251, the second guide member 252, and the third guide member 253. That is, the output destination of the first carry-in path 21 a is guided by the first guide member 251, the output destination of the second carry-in path 23 a is guided by the second guide member 252, and the first guide member 251 and the second guide member 252 The output destination is guided by the third guide member 253. Therefore, it is possible to stabilize the conveyance path of the paper connected from the upstream side to the downstream side.

  In the present embodiment, a guide structure is realized by the first movable guide member 251a and the first fixed guide member 251b. That is, after the direction of the sheet conveyed from the first carry-in path 21a is changed by the first movable guide member 251a, the sheet guided by the first movable guide member 251a can be guided by the first fixed guide member 251b. .

  Therefore, since the upstream side has a movable structure and the downstream side has a fixed structure, the first movable guide member 251a overlaps the other movable second movable guide member 252a and the third movable guide member 253a at the intersection A. There is no need. For example, conventionally, each of the movable guide structures has a comb-teeth shape, and it has been necessary to realize a crossing path by overlapping the movable guide members. There was a risk of JAM due to clogging.

  On the other hand, in the present embodiment, an intersecting path that avoids overlapping of movable guide members is realized by the movable guide by the first movable guide member 251a and the fixed guide by the first fixed guide member 251b. Thus, the sheet can be transported without causing JAM at the intersection A between the first carry-in path 21a and the downstream transport path.

  In the present embodiment, a guide structure is realized by the second movable guide member 252a and the second fixed guide member 252b. That is, after the direction of the sheet conveyed from the second carry-in path 23a is changed by the second movable guide member 252a, the sheet guided by the second movable guide member 252a can be guided by the second fixed guide member 252b. .

  Therefore, since the upstream side has a movable structure and the downstream side has a fixed structure, the second movable guide member 252a overlaps the other movable first movable guide member 251a and the third movable guide member 253a at the intersection A. There is no need.

  In the present embodiment, an intersecting path that avoids overlap between movable guide members is realized by the movable guide by the second movable guide member 252a and the fixed guide by the second fixed guide member 252b. As a result, the sheet can be transported without causing JAM at the intersection A between the second carry-in path 23a and the downstream transport path.

  In the present embodiment, a guide structure is realized by the third movable guide member 253a and the third fixed guide member 253b. That is, in any case of the sheet guided toward the first discharge path 21b and the sheet guided toward the second discharge path 23b, the third movable guide member 253a and the third fixed guide member 253b The sheet can be guided from the upstream side to the downstream side.

  Therefore, since the upstream side has a movable structure and the downstream side has a fixed structure, the third movable guide member 253a overlaps the other movable first movable guide member 251a and the second movable guide member 252a at the intersection A. There is no need.

  In the present embodiment, a crossing path that avoids overlap between movable guide members is realized by the movable guide by the third movable guide member 253a and the fixed guide by the third fixed guide member 253b. As a result, the sheet can be transported without causing JAM at the intersection A between one of the first transport path 21a and the second transport path 23a and the transport path on the downstream side.

  In the present embodiment, the upstream surface of the third movable guide member 253a in the direction in which the paper is guided is corrected to a position away from the direction in which the paper is guided by the first angle B, and the paper The downstream surface in the direction in which the sheet is guided is corrected to a position along the direction in which the sheet is guided. Therefore, even if the paper is curled, the paper can be scooped. Therefore, it is possible to transport the paper without generating JAM by the third movable guide member 253a.

  In the present embodiment, the first facing surface 257 provided in the first fixed guide member 251b is disposed at a position away from the second path 23 by the second angle C, and the second facing surface provided in the second fixed guide member 252b. The surface 258 is disposed at a position away from the first path 21 by the second angle C. Therefore, even if the paper is curled, the paper can be scooped. Accordingly, the paper is conveyed without generating JAM between the third movable guide member 253a and the first fixed guide member 251b and between the third movable guide member 253a and the second fixed guide member 252b. Can be made.

As shown in FIG. 4, the first movable guide member 251a can realize the first movable amount of the movable angle α. The second movable guide member 252a can realize the second movable amount of the movable angle β. The third movable guide member 253a can realize the third movable amount of the movable angle γ. The movable angle α is, for example, 30 °. The movable angle β is, for example, 30 °. The movable angle γ is 60 °, for example.

  FIG. 5 illustrates the first lever 251c, the second lever 252c, and the third lever 253c, the first movable guide member 251a, the second movable guide member 252a, and the third movable guide member 253a according to the second embodiment of the present invention. It is a figure which shows an example of the positional relationship of these.

  The first lever 251c is attached to the first movable guide member 251a, and the movable amount of the first movable guide member 251a can be adjusted within the range of the first movable amount. The second lever 252c is attached to the second movable guide member 252a and the first lever 251c, and the movable amount of the second movable guide member 252a can be adjusted within the range of the second movable amount. The third lever 253c is attached to the third movable guide member 253a, and the movable amount of the third movable guide member 253a can be adjusted within the range of the third movable amount.

  The third movable amount is adjusted to be larger than the first movable amount. The first movable amount is adjusted to the same movable amount as the second movable amount. Specifically, as shown in FIG. 5, the lever ratio of the first lever 251c, the second lever 252c, and the third lever 253c is Y: Y: X, and the first lever 251c and the second lever 252c, The lever ratio with the third lever 253c is set to 2: 1.

  Y in the first lever 251c is determined by the distance between the shaft member 271 and the shaft member 272. The shaft member 271 connects the first movable guide member 251a and the first lever 251c. The first movable guide member 251 a is driven to rotate around the shaft member 271 by the rotation of the shaft member 271.

  Y in the second lever 252c is determined by the distance between the shaft member 274 and the shaft member 278. The shaft member 278 connects the second movable guide member 252a and the second lever 252c. The second movable guide member 252a is rotationally driven around the shaft member 278 by the rotation of the shaft member 278.

  Y in the third lever 253c is determined by the distance between the shaft member 275 and the shaft member 276. The shaft member 275 connects the third movable guide member 253a and the third lever 253c. The third movable guide member 253a is driven to rotate around the shaft member 275 by the rotation of the shaft member 275.

  FIG. 6 is a diagram illustrating an example of the first lever 251c, the second lever 252c, and the third lever 253c according to the second embodiment of the present invention. A rotating member 282 is attached to the shaft member 272. A rotating member 281 is attached to the shaft member 274. A rotating member 283 is attached to the shaft member 276. The rotating members 281 to 283 are disposed at positions where the rotating members 281 to 283 are in contact with the base 261. The base 261 is supported by the support members 262 and 263 via rotatable shaft members 273 and 277.

  The support member 262 receives the rotational force of the transmission member 291 via the shaft member 279. The transmission member 291 is provided with a driving force by the driving source 16 shown in FIG. Specifically, the rotational force generated by the transmission member 291 is transmitted to the base 261 via the shaft member 279, the support member 262, and the shaft member 273. Although not shown, the driving force from the driving source 16 is transmitted to the support member 263 as well as the support member 262. Therefore, the position of the base 261 is controlled by the drive source 16. Since the rotation members 281 to 283 are in contact with the pedestal 261, the positions of the rotation members 281 to 283 vary by controlling the position of the pedestal 261. Accordingly, the positions of the first lever 251c, the second lever 252c, and the third lever 253c are changed, so that the first movable guide member 251a, the second movable guide member 252a, and the third movable guide member 253a are moved.

  That is, the drive source 16 drives the first lever 251c, the second lever 252c, and the third lever 253c. Specifically, the drive source 16 includes the first movable guide member 251a, the second movable guide member 252a, and the third movable guide member 253a via the first lever 251c, the second lever 252c, and the third lever 253c. Interlock.

  From the above description, according to the present embodiment, the third movable guide member 253a functions as a branch guide at the intersection A because the third movable amount is larger than the first movable amount and the second movable amount. Therefore, even if there is an intersection A in the transport path, the branch guide can be realized with a simple configuration, and thus the transport path can be stabilized at a low cost.

  Further, according to the present embodiment, the first lever 251c, the second lever 252c, and the third lever 253c are used in the first movable guide member 251a, the second movable guide member 252a, and the third movable guide member 253a. Different movable amounts can be realized by one drive source 16. Accordingly, different movable amounts can be realized without providing a driving motor or the like in each of the first movable guide member 251a, the second movable guide member 252a, and the third movable guide member 253a, and therefore, different at a low cost. A movable amount can be realized.

  As described above, the paper conveying apparatus 1 according to the present invention has been described based on the embodiment. However, the present invention is not limited to this, and modifications may be made without departing from the spirit of the present invention.

  For example, in the present embodiment, an example in which the decurler 33 is disposed in the paper transport apparatus 1 has been described, but the present invention is not particularly limited thereto. For example, the paper transport device 1 may be a post-processing device that performs post-processing of paper. Further, the sheet conveying apparatus 1 may be an image forming apparatus or a relay apparatus. That is, any device may be used as long as the route including the intersection A described above is arranged.

  In the present embodiment, an example in which the first path 21 is disposed as a path for transporting paper in the horizontal direction and the second path 23 is disposed as a path for transporting paper in the vertical direction has been described. Not limited to this, the first path 21 may be arranged as a path for conveying the paper in the vertical direction, and the second path 23 may be arranged as a path for conveying the paper in the horizontal direction.

  Moreover, in this embodiment, although the 3rd movable guide member 253a demonstrated an example provided with the 1st surface 254 and the 2nd surface 255, the 1st surface 254 and the 2nd surface 255 may be 1 set. Multiple sets may be used. When formed in a plurality of sets, for example, the third movable guide member 253a may be arranged in a comb-teeth shape in which a plurality of members including the first surface 254 and the second surface 255 are arranged at a constant pitch. Even in such a structure, the movable guide members do not overlap with each other due to the arrangement of the first fixed guide member 251b and the second fixed guide member 252b, so that JAM occurs at the intersection A. The sheet can be conveyed without the need to do so.

  In the present embodiment, an example in which the first angle B is, for example, 25 ° and the second angle C is, for example, 20 ° has been described. However, the present invention is not limited thereto, and the sheet can be stably conveyed. Any angle is acceptable.

  In the present embodiment, an example has been described in which the movable angle α is, for example, 30 °, the movable angle β is, for example, 30 °, and the movable angle γ is, for example, 60 °. It is sufficient that the movable amount is adjusted to be larger than the first movable amount and the second movable amount.

  In the present embodiment, an example in which the first movable amount, the second movable amount, and the third movable amount are adjusted by the lever ratio has been described. However, the present invention is not limited thereto, and the gear transmission member and the belt drive transmission member are not limited. You may adjust by gear ratio by using.
