Image forming device

Abstract

The present invention provides an image forming apparatus having a double-sided copying function, characterized by comprising: a document detection unit for detecting the size of a document, and a document size setting unit for setting the size of the document according to requirements. At least one; the top position setting unit of the original, which sets the top position of the original according to the requirements; the printing mode setting unit, which sets from double-sided to double-sided, from single-sided to double-sided, from double-sided to single-sided One side, one printing mode from one side to one side; the binding direction setting unit is used to set the binding direction of the original document and the binding direction of the output paper according to the requirements; the output size setting unit is set according to the requirements The size of the output paper; the printing magnification setting unit, which sets the printing magnification according to the requirements; and the copy area determining unit, when the top position of the original is set as the upper, and the upper left corner of the original is used as a reference. Specify the copy area.

Description

technical field [0001] The present invention relates to an image forming apparatus. Background technique [0002] Conventionally, there are known image forming apparatuses that read and record on one side of a plurality of original documents, print (record) the original on both sides of recording paper (output paper), or read and record on both sides of the original, And the original is printed on both sides or one side of the recording paper. In various double-sided recording modes of the image forming apparatus described above, sometimes a recording paper having a size α times the original paper is copied at a magnification ratio (printing magnification) times β. [0003] Here, when α = β, there is no problem because simply enlarged and reduced printing is performed, but when α ≠ β, the image of the original document may be recorded on both the front and back sides of the recording paper with a shift. In this regard, there is known an image forming apparatus that solves ...

AI Technical Summary

Problems solved by technology

That is, when performing double-sided copying, it is impossible to predict which part of the back side of the original document will be printed on which part of the recording paper, thereby causing the problem that double-sided copying cannot be performed according to the user's intention.
