A stencil printing machine of the present invention has an inner press roller ( ) arranged in the inside of a printing drum ( ), an inner press mechanism ( ) for shifting the inner press roller ( ) between a pressure position (B) and a standby position and for adjusting a pressure power of the inner press roller ( ) at the pressure position (B). At the pressure position (B), the inner press roller ( ) presses the inner peripheral surface of a screen ( ) forming a peripheral wall of the printing drum ( ). At the standby position, the inner press roller ( ) is separated from the inner peripheral surface. During printing, the inner press roller ( ) is positioned at the pressure position (B) at which the inner press roller ( ) presses the inner peripheral surface of the screen ( ). The inner press mechanism ( ) has an ink supply unit ( ) arranged at the inside of the printing drum ( ) in order to shift the inner press roller ( ) between the pressure position (B) and the standby position. A power transfer section ( ) is arranged in the outside of the printing drum ( ). The power transfer section ( ) transfers the driving power to the ink supply unit ( ) in order to shift the inner press roller ( ) between the pressure position (B) and the standby position and also in order to adjust the pressure power of the inner press roller ( ) at the pressure position (B).
