1. A transporter that holds a product cut out from a plate-shaped workpiece, picks up the product from the workpiece, and transports the product, the transporter comprising:
a traveling body;
a supporting body on the traveling body and including a first member and a second member with relative positions that can be mutually changed;
a first suction pad on the first member to adhere to the product;
a second suction pad on the second member to adhere to the product;
a first presser on the first member and capable of being raised or lowered independent of the first suction pad;
a second presser on the second member and capable of being raised or lowered independent of the second suction pad, the first and second suction pads being between the first and second pressers; and
a controller configured or programmed to control the relative positions of the first member and the second member so that the first suction pad and the second suction pad are positioned inside a contour of the product to be picked up, and the first presser and the second presser are positioned above the workpiece outside the product to be picked up; wherein
the first presser is provided on the first member via an elastic body, and in a state of having been lowered, a lower end of the first presser is positioned below a lower end of the first suction pad;
the second presser is provided on the second member via an elastic body, and in a state of having been lowered, a lower end of the second presser is positioned below a lower end of the second suction pad;
the second member includes a lift driver to raise or lower each of a plurality of second pressers including the second presser;
the controller is configured or programmed to cause the lift driver to raise one of the plurality of second pressers, which is positioned above the product to be picked up and between the first presser and the second presser positioned outside the product to be picked up, above the lower end of the second suction pad; and
the controller is configured or programmed to select suction pads positioned above the product to be picked up and between the first presser and the second presser positioned outside the product to be picked up, including the first suction pad and the second suction pad, to be used to adhere to the product.
