  • Patent number: 12037151
    Abstract: A box transport rail 70 extending in the box transport direction Tb and a plurality of box transport shuttles 76 movably arranged on the box transport rail 70 to be movable in the box transport direction Tb, which is the movement direction of a packing box Bx, are provided. When located in the sheet feeder 81, the box transport shuttles 76 receive the sheet 9 while being apart from each other across an interval greater than the bottom sheet portion 91 of the sheet 9. During movement from the pushing unit 82 to the sealer 84, the box transport shuttle 76 arranged frontward in the box transport direction Tb is brought close to the bottom sheet portion 91 to reduce the angle of a part 93 frontward of the bottom sheet portion 91 in the box transport direction Tb relative to the bottom sheet portion 91.

  • Patent number: 11933726
    Abstract: A measurement apparatus includes a generator that causes electromagnetic waves to be incident on a sample, a receiver that receives electromagnetic waves reflected by the sample, and a controller that controls the generator and receiver. The sample includes a first layer on which the electromagnetic waves are incident and a second layer stacked on the first layer. The controller detects whether a third layer is present between the first and second layers based on the electromagnetic waves incident on the sample from the generator and the electromagnetic waves received by the receiver. The generator causes the electromagnetic waves to be incident at an angle such that the electromagnetic waves are totally reflected between the first and third layers and/or between the first and second layers.
