Abstract

A stencil printer includes a document size sensing device for sensing the size of a document and a paper size sensing device for sensing the size of papers. A controller determines the orientation and size of the document and those of the paper on the basis of information output from the two sensing devices. If the document and paper are different in orientation, the controller controls a master making section on the basis of the orientation of the papers for forming a document image in a master in accordance with the orientation of the paper. At the same time, the controller controls a side fence moving device and an end fence moving device such that side fences and an end fence mounted on a paper discharge tray each are located at a particular position matching with the size of the papers. The side fences are movable in the widthwise direction of the paper while the end fence is movable forward and backward in the direction of paper discharge.

Dependent claims

A stencil printer comprising:

an ink drum for wrapping a master around an outer periphery thereof;
master making means for making the master;
a paper discharging section including a paper discharge tray having a pair of side fences spaced from each other in a widthwise direction of a paper and movable in said widthwise direction and an end fence selectively movable forward or backward in a direction of paper discharge;
side fence moving means for moving said pair of side fences in the widthwise direction;
end fence moving means for moving said end fence in the direction of paper discharge;
document size sensing means for sensing a size of a document;
paper size sensing means for sensing a size of the paper;
and
control means for controlling said master making means, said side fence moving means and said end fence moving means;
said control means determining, based on information output from said document size sensing means and said paper size sensing means, an orientation of the document, an orientation of the paper and a size of said paper and controlling, if said document and said paper are different in orientation, said master making means on the basis of the orientation of said paper to thereby orient a document image to be formed in the master in accordance with the orientation of said paper, and controlling said side fence moving means and said end fence moving means for locating each of said pair of side fences and said end fence at a particular position matching with the size of said paper.
