Stencil printing method and apparatus

A stencil printing apparatus which comprises

• a pressure chamber having a first wall and a second wall both of which face each other and are built up together via a frame-like packing, said first wall comprising a frame member which has sufficient flexibility to bend in all directions in response to a reduction in pressure in said pressure chamber and on which a flexible diaphragm is extended,
• means for supporting a stencil so as to have the stencil disposed opposite to said diaphragm in the pressure chamber,
• means for supporting printing paper so as to have the printing paper disposed between the stencil and the second wall in the pressure chamber, and
• means for reducing pressure in the pressure chamber.

A stencil printing apparatus which comprises

• a wall comprising a frame member on which a diaphragm having flexibility is extended,
• a frame-like packing disposed on said frame member to define a sealed chamber between said wall and a surface on which said wall is placed via said packing,
• means for supporting a stencil so as to have the stencil disposed opposite to said diaphragm, and
• means for reducing pressure in said chamber space,
• said frame member being sufficiently flexible to be capable of bending in all directions in response to a reduction in pressure in said chamber.
