  • the movement of the opening arm 110, 910 from the lower to the upper holding position is substantially perpendicular to the plane of the paper in a direction perpendicular to the plane of the paper along a length of the guide path 135.
  • the projection 115, 116, 120, 923, 914 slides during the movement of the Opening arm from the lower to the upper holding position on the walls 133a, 131c and 132c over.
  • Fig. 34A shows a guide rail 930 in a sectional view, wherein the sectional plane is selected substantially perpendicular to a direction of movement of the opening arm 110, 910 and substantially along a length of a guide shaft 129, 929.
  • the guide rail 930 has a guideway 135 formed as a passage.
  • the guide rail 930 has a guide track 935.
  • the guideway 935 has the lateral wall sections 931 and 932.
  • the wall portions 931 and 932 each have a first wall (surface) 931a and 932a, a second wall (surface) 931b and 932b and a third wall (surface) 931c and 932c, respectively.
  • the third wall 931c or 932c of the first and second wall sections 931 and 932 delimit the guide track 935. Since the guide track 935 is designed as a passage, the guide rail 930 has no third wall section.
  • Fig. 34B the guide rail 930 is off Fig. 34A shown, wherein in the guide track 935, a lateral or middle projection 115, 116, 120, 923, 914 of an opening arm 110, 910 engages.
  • the movement of the opening arm 110, 910 from the lower to the upper holding position is substantially perpendicular to the paper plane in a direction perpendicular to the paper plane along a length of the guide track 935.
  • the projection 115, 116, 120, 923, 914 slides past the walls 933a, 931c and 132c as the opening arm 110, 910 moves from the lower to the upper holding position.
