The block 303B is provided so as to move along both screw shafts 305B and 306B when the second screw shaft 306B rotates. Therefore, according to the adjusting mechanism 34, the first screw shafts 305A and 305B are rotated by the drive source to move the first load body 32 so that the position of the guide surface 31 is the length of the sheet in the first direction. The second load body 33 is moved by rotating the second screw shafts 306A and 306B, and the guide surface 31 and the sphere of the second load body 33 as shown in FIG. The distance T between 331 can be adjusted.

  2 to 5 show the case where the distance T is the minimum, and FIGS. 6 to 8 show the case where the distance T is the maximum.

  Next, the operation of the cross transfer apparatus having the above configuration will be described.

  First, before starting the conveyance, the adjustment mechanism 34 is operated to move the first load body 32 and / or the second load body 33 so that the position of the guide surface 31 is the length of the sheet in the first direction. The distance T between the guide surface 31 and the sphere 331 of the rotation assembly 330 of the second load body 33 is adjusted in accordance with the dimensions. As shown in FIG. 9, the distance T is directed from the rotation assembly 330 toward the guide surface 31 with respect to the paper 100 in a state where the fold line 101 of the paper 100 is in contact with the guide surface 31 (that is, in the direction of arrow F). Set to the magnitude to which the load force is applied. The size of the distance T is determined depending on the type of paper, particularly the material and thickness of the paper. In the case of FIGS. 6 to 8, the distance T is adjusted by moving only the second load body 3.

  When the operation of the apparatus is started, first, the feed roller 1 is actuated to feed the paper 100 in the first direction with the fold 101 as the head, the paper 100 is placed on the transport surface 20, and the fold 101 is It passes under the sphere 331 of the rotation assembly 330 and the sphere 321 of the rotation assembly 320 and contacts the guide surface 31. At this time, since the sphere 331 has the gap D2 between the sphere 331 and the sphere 321, the sphere 321 can move upward to pass the crease 101, and the sphere 321 has a gap D1 between the sphere 321 and the rotation roller 322. Since it has, it can move upward to pass the crease 101. Therefore, the crease 101 passes under the spheres 331 and 321 without any trouble. Moreover, even if the spheres 331 and 321 move upward, the spherical bodies 331 and 321 do not escape upward because of the rotation rollers 332 and 322.

  Then, the transport roller 2 operates. Thereby, the paper 100 is conveyed in the direction of the arrow C, that is, the paper 100 is conveyed in the second direction while being conveyed to the alignment guide 3 side. At this time, since the load is applied to the paper 100 from above by the spheres 331 and 321, the paper 100 is strongly transported by the transport roller 2, and is thus reliably transported without slipping.

  By the way, the folded sheet 100 tends to move away from the guide surface 31 of the alignment guide 3 as shown in FIG. . However, in the cross conveyance device 10 configured as described above, since the sphere 331 of the second load body 33 applies a load in the direction of arrow F to the paper 100, the paper 100 tends to move away from the guide surface 31. Is prevented.

  Therefore, according to the cross conveyance device 10 configured as described above, the folded sheet 100 can be prevented from moving away from the guide surface 31 of the alignment guide 3, and thus the folded sheet 100 can be reliably transferred to the alignment guide. 3 along the guide surface 31.
