With such a configuration, when the PDP is suction-held, the rotation of the PDP suction-holding mechanism about two orthogonal axes as center axes is regulated. Therefore, the PDP suction-holding mechanism is fixed, and accurate positioning is performed. It can be carried out. Further, when the FPC is crimped to a terminal provided at the end of the glass of the plasma display panel, the regulation of the rotation of the PDP suction holding mechanism about two orthogonal axes as center axes is released, and the PDP suction holding mechanism is released. Since it is possible to rotate around two orthogonal axes as center axes, F
When the PC crimping mechanism presses the FPC across the glass end of the PDP, the PDP suction holding mechanism rotates according to the applied force, peeling off the glass applied near the glass end or causing cracks. The power can be reduced.
