A stencil printing machine of the present invention has an inner press roller (47) arranged in the inside of a printing drum (16), an inner press mechanism (20) for shifting the inner press roller (47) between a pressure position (B) and a standby position and for adjusting a pressure power of the inner press roller (47) at the pressure position (B). At the pressure position (B), the inner press roller (47) presses the inner peripheral surface of a screen (19) forming a peripheral wall of the printing drum (16). At the standby position, the inner press roller (47) is separated from the inner peripheral surface. During printing, the inner press roller (47) is positioned at the pressure position (B) at which the inner press roller (47) presses the inner peripheral surface of the screen (19). The inner press mechanism (20) has an ink supply unit (38) arranged at the inside of the printing drum (16) in order to shift the inner press roller (47) between the pressure position (B) and the standby position. A power transfer section (39) is arranged in the outside of the printing drum (16). The power transfer section (39) transfers the driving power to the ink supply unit (38) in order to shift the inner press roller (47) between the pressure position (B) and the standby position and also in order to adjust the pressure power of the inner press roller (47) at the pressure position (B).
