Abstract:
A stencil leading end mounting device of a printing drum of a rotary stencil printer, comprising:a base member having a stencil leading end supporting surface incorporating a magnet therein, the stencil leading end supporting surface extending along a generatrix of the printing drum for receiving thereon a leading end of a stencil to be mounted around the printing drum; a clamp member having a clamp portion formed with a stencil clamping surface and a drive portion opposite to the clamp portion, the clamp member being supported on the base member to be tiltable relative to the stencil leading end supporting surface between a closed position in which the clamp portion is laid over the stencil leading end supporting surface so as to clamp the stencil leading end between the stencil leading end supporting surface and the stencil clamping surface under a magnetic attraction of the clamp portion by the magnet toward the stencil leading end supporting surface and an open position in which the stencil clamping surface is inclined apart relative to the stencil leading end supporting surface so as to expose an inter space therebetween for entrance thereto and removal therefrom of the stencil leading end; pivot means for providing a linear pivot axis between the base member and the clamp member for the clamp member to tilt thereabout between the closed position and the open position with the linear pivot axis being positioned between the clamp portion and the drive portion of the clamp member; and actuation means for selectively biasing the drive portion of the clamp member for tilting the clamp member from the closed position to the open position, wherein the pivot means provide the linear pivot axis so as to move relative to the clamp member from a side of the clamp portion to a side of the drive portion according to a progress of tilting of the clamp member away from the closed position toward the open position.
