ABSTRACT:
A conveying route along which the leading edge side of a roll stencil sheet is conveyed to a stencil sheet clamp section of a printing drum is formed. Along the conveying route, arranged are: a writing head which forms a perforated image on the stencil sheet; a platen roller on which the writing head is brought into pressure contact and which conveys the stencil sheet; a stencil sheet cutter which cuts the stencil sheet; a stencil positioning sensor which detects a leading edge of the stencil sheet; and storage means for temporarily storing the stencil sheet. Control means for controlling a timing with which the printing drum is rotated to start loading of the stencil sheet is included, the control means controlling the timing to be an arbitrary time between an earliest timing earlier, by a time period obtained by dividing a conveying distance between the stencil sheet cutter and the stencil sheet clamp section by a peripheral speed of the platen roller, than a timing with which the writing head completes forming a perforated image on the stencil sheet and a latest timing which is a same timing as completion of release of stencil making pressure.
