Abstract
An Flat Bed-Multi Function Device includes an MPU, a reading section, a recording section, an operation section, an image memory, and a ratio changing section. In a reduction copy mode, the reading section reads an extended reading area of a document larger than a recording area of recording paper to generate image data. The ratio changing section reduces the image data at a predetermined reduction ratio. The recording section forms an image on a sheet of recording paper on the basis of the reduced image data.
Claims36
A copying machine comprising:
- a reading unit which reads a document to generate image data;
- a reducing unit which reduces the image data at a predetermined reduction ratio to generate reduced image data;
- and
- a recording unit which forms an image in a first recording area on a recording medium on the basis of one of the image data generated by the reading unit and the reduced image data generated by the reducing unit, wherein:
- the first recording area corresponds to the recording medium, and
- at least when the recording unit forms the image on the basis of the reduced image data, the reading unit reads an extended reading area of the document larger than a second recording area corresponding to a size of the document.

A copying method comprising:
- reading a document to generate image data;
- reducing the image data at a predetermined reduction ratio to generate reduced image data;
- and
- forming an image in a predetermined recording area on a recording medium on the basis of one of the image data generated in the reading and the reduced image data generated in the reducing, wherein:
- at least when in the forming, the image is formed on the basis of the reduced image data, an extended reading area of the document, which is larger than the recording area, is read in the reading.
2 more elements
A copying machine comprising:
- a reduction ratio setting section which sets a reduction ratio;
- a control section which compares the reduction ratio with a threshold value;
- an effective area setting section which detects a length of a document in a main scanning direction to set an effective area being larger than a recording area having a size of the document;
- a reading section which reads the document to generate image data;
- a data processing section which reduces the image data on the basis of a comparison result provided by the control section, the image data, and the effective area;
- and
- a recording section which forms an image on a recording area of a recording medium on the basis of the image data reduced by the data processing section.
