To provide a sheet carrying method and its device capable of gripping a sheet supplied by a simplified device in an undislocated state.

Two corner parts of a supply sheet W supplied on an idle stage S, are imaged by two CCD cameras 8a and 8b, and two-point imaging coordinates being the corner parts are taken in a control device N, and these two-point imaging coordinates and a dislocation quantity of the two-point coordinates being the corner parts of a model sheet MW taken in as a normal position in advance, are comparatively arithmetically operated. The sheet on the idle stage S is gripped by controlling a gripping part of a first delivery robot 5A by a driving unit H by correcting by the dislocation quantity.
