Abstract
A printer of the present invention includes a print drum around which a master made by cutting a stencil is to be wrapped, an ink feeding device for feeding ink to the master wrapped around the print drum and a pressing member for pressing a sheet relatively to the print drum to thereby print an image on the sheet. The operator of the printer is capable of selecting either one of a usual print mode and a silence print mode that give priority to image quality and noise reduction, respectively.
Claims14
A printer, comprising:
- a print drum configured to wrap a master produced from a stencil therearound;
- ink feeding means for feeding ink to the master wrapped around said print drum;
- pressing means for pressing a sheet relatively to said print drum to thereby print an image on said sheet;
- a controller configured to implement at least one of a usual print mode giving priority to image quality and a silence print mode giving priority to noise reduction, the usual print mode and the silence print mode both having a pressing force, an air volume, and a print speed associated therewith;
- pressure control means for driving a press motor in accordance with a signal output from said controller to cause a spring to selectively extend and contract to vary a pressure force of said pressing means acting on said print drum;
- and
- a unit including at least one fan and blowing/peeling means for regulating a stream of air sent from said at least one fan, wherein
- said controller operates said press motor in such a manner as to provide said pressing means with a standard pressing force assigned to said usual print mode and to provide said pressing means with a reduced pressing force assigned to said silence print mode, said blowing/peeling means controls a rotation speed of said at least one fan such that a standard volume of air is sent from said at least one fan when the usual print mode is selected, and a lower standard volume of air is sent from at least one fan when the silence print mode is selected.
