The operation|movement of the sheet|seat sticking apparatus EA mentioned above is demonstrated. First, as shown in (A) in FIG. 1 , the user of the sheet attaching device EA (hereinafter simply referred to as "user") sets the raw material sheet RS to the sheet attaching device EA, and the sheet attaching device EA Each component is arranged at the initial position shown by the solid line in the figure. After the raw sheet RS is set, a signal to start automatic operation is input through an operation unit (not shown) such as an operation panel or a personal computer. Then, the supply unit 10 drives the rotating motor 15A to pull out the raw material sheet RS. As shown by the solid line in FIG. At a predetermined length, the drive of the rotation motor 15A is stopped.

Next, as shown in (A) in FIG. 1 , when the user or an unillustrated conveying unit such as an articulated robot or a conveyor belt places the adhered body WK on the support surface 33A so that the reference position WKR and the table center 33R When overlapping, the moving unit 30 drives a decompression unit (not shown), and starts suction and holding by the supporting surface 33A. In addition, the supply unit 10 drives the rotary motor 15A, and pulls out the raw material sheet RS, as shown by the two-dot chain line in (A) in FIG. Book a spot. At this time, the leading end portion of the adhesive sheet AS in the feeding direction is urged by an unshown air nozzle, an ion generator, or other urging means, and is brought into a state of being in contact with the front of the pressing roller 21 .

Afterwards, the moving unit 30 drives the linear motor 31 to move the adhered body WK to the left, and as shown in (B) and (C) in FIG. When the platen centers 34R coincide, the drive of the linear motor 31 is stopped. At this time, the leading end portion of the adhesive sheet AS in the supply direction is in a state of being sandwiched between the pressing roller 21 and the outer edge end surface WKE of the adherend WK as shown in (B) of FIG. 1 , and becomes the first pressing roller. 51.
