Abstract: A printer has a mask sheet 25, a movable print stage 3, a camera head 40 provided with a mask recognition camera 41 and a board recognition camera 42, and a controller that controls the foregoing members. The controller drives the camera head 40 under its control so that mark recognition on a board W is executed using the board recognition camera 42 and mark recognition on the mask sheet 25 is executed periodically a plurality of times using the mask recognition camera 41 while the same mask sheet is used. Also, in order to superimpose the board W on the mask sheet 25, the controller finds a correction amount corresponding to a displacement between the mask sheet 25 and the board W according to latest mask position information acquired through mark recognition on the mask sheet 25 and board position information of the board and drives the print stage 3 according to the correction amount under its control.

Abstract: A printing device capable of improving the printing accuracy by preventing positional displacement of a stencil applies paste on a stencil onto a substrate by spreading the paste by sliding a squeegee along a surface of the stencil disposed on the substrate. Outer attracting means for holding the stencil by attracting an undersurface side thereof is provided on the outside of a squeegee sliding region in which the squeegee slides over the stencil.

Abstract: [Problems] To provide a printing device capable of improving the printing accuracy by preventing positional displacement of a stencil. [Means for Solving the Problems] A printing device of the invention applies paste on a stencil 51 onto a substrate by spreading the paste by sliding a squeegee 61 along a surface of the stencil 51 disposed on the substrate W. Outer attracting means for holding the stencil 51 by attracting an undersurface side thereof is provided on the outside of a squeegee sliding region in which the squeegee 61 slides over the stencil 51.
