PURPOSE:To keep the release timing of a press roller to a stencil constant regardless of a rotary moving amount by interlocking a rotary moving lever with a press roller releasing lever through a link mechanism. CONSTITUTION:When a lever 4 is revolved to a counterclockwise direction from such a state that a rotary moving amount is + or -0 (a rotary moving lever 4 and a cam roller 29 are set to the position shown by a chain line) to set the rotary moving amount to the + side (the lever 4 is set to the position shown by a solid line), a cam 12 is also revolved to a counterclockwise direction along with a lower cylinder 2 but, in this case, because a link mechanism consisting of a bell crank 20 and a link 24 tilts the release lever 26 of a press roller 11 through a pin 21 and moves the cam roller 29 provided to the leading end of the lever 26 to a counterclockwise direction along a cam surface (the position shown by the solid line), the revolving amount of the aforementioned cam 12 is almost negated and the release timing of the press roller is kept constant. |
