Image recorder for properly orienting output images

Claim 2

An image recorder comprising: inputting means for inputting input image data representative of a document comprising a plurality of paper sheets which may be oriented in different directions; storing means for storing the input image data inputted by said inputting means; direction determining means for processing the input image data stored in said storing means to determine a direction of character data included in said input image data, wherein the direction determining means detects the direction of a plurality of character elements and the direction of the character data is determined based on a majority of the detected directions of the plurality of character elements; direction changing means for changing, when the determined direction of the character data determined by said direction determining means differs from a predetermined direction, an orientation of an output image data including a plurality of sheets of output image data, corresponding to the plurality of sheets of the input image data, relative to the input image data by turning said output image data upside down or rotating said output image data so that each of the plurality of sheets of the output image data is consistently oriented; and recording means for recording the output image data consistently oriented in the predetermined direction on a predetermined recording medium.

Claim 3

An image recorder as claimed in claim 1, wherein said direction changing means generates, when the output image is rotated, said output image in a particular magnification by enlargement or reduction based on a size of an input image in a widthwise or lengthwise direction and a size of the recording medium in a lengthwise or widthwise direction.

Claim 4

An image recorder as claimed in claim 1, wherein said direction changing means generates, when an output image is rotated, said output image by arranging the character data in positions different from positions in the input image based on a size of said input image in a widthwise or lengthwise direction and a size of a recording medium on which the output image data is recorded in a lengthwise or widthwise direction.

Claim 5

An image recorder as claimed in claim 1, wherein said direction changing means arranges, when the output image is rotated, the character data in positions different from positions in the input image data based on a size of said input image in a widthwise or lengthwise direction and a size of a recording medium on which the output image data is recorded in a lengthwise or widthwise direction, identifies a first blank area between consecutive character lines in said input image, and forms a second blank area of a same spacing as said first blank area between consecutive character lines of said output image data.

Claim 6

An image recorder comprising: inputting means for inputting input image data representative of a document comprising a plurality of paper sheets which may be oriented in different directions; storing means for storing the input image data inputted by said inputting means; direction determining means for processing the input image data stored in said storing means to determine a direction of character data included in said input image data, wherein the direction determining means detects the direction of a plurality of character elements and the direction of the character data is determined based on a majority of the detected directions of the plurality of character elements; direction changing means for changing, when the determined direction of the character data determined by said direction determining means differs from a predetermined direction, an orientation of an output image data including a plurality of sheets of an output image data, corresponding to the plurality of sheets of the input image data, relative to the input image data by turning said output image data upside down or rotating said output image data so that each of the plurality of sheets of the output image data is oriented consistently; and recording means for recording the output image data oriented consistently in the predetermined direction on a predetermined recording medium; wherein said recording means records an image on the front and the rear of each recording medium, said direction changing means determining the predetermined direction in conformity to a direction of characters of an image to be recorded on the front and, only for an image to be recorded on the rear, changing an orientation of an output image only if a direction of characters of an input image differs from said predetermined direction.

Claim 7

An image recorder comprising: inputting means for inputting input image data representative of a document comprising a plurality of paper sheets which may be oriented in different directions; storing means for storing the input image data inputted by said inputting means; direction determining means for processing the input image data stored in said storing means to determine a direction of character data included in said input image data, wherein the direction determining means detects the direction of a plurality of character elements and the direction of the character data is determined based on a majority of the detected directions of the plurality of character elements; direction changing means for changing, when the determined direction of the character data determined by said direction determining means differs from a predetermined direction, an orientation of an output image data including a plurality of sheets of an output image data, corresponding to the plurality of sheets of the input image data, relative to the input image data by turning said output image data upside down or rotating said output image data so that each of the plurality of sheets of the output image data is oriented consistently; and recording means for recording the output image data oriented consistently in the predetermined direction on a predetermined recording medium; wherein said recording means records an image on the front and the rear of each recording medium, said direction changing means determining the predetermined direction in conformity to a direction of characters of an image to be recorded on the front and, only for an image to be recorded on the rear, changing an orientation of an output image only if a direction of characters of an input image differs from said predetermined direction.

Claim 8

An image recorder as claimed in claim 5, wherein said direction changing means generates, when the output image is rotated, said output image in a particular magnification by enlargement or reduction based on a size of an input image in a widthwise or lengthwise direction and a size of the recording medium in a lengthwise or widthwise direction.

Claim 9

An image recorder as claimed in claim 5, wherein said direction changing means generates, when an output image is rotated, said output image by arranging the character data in positions different from positions in the input image based on a size of said input image in a widthwise or lengthwise direction and a size of a recording medium on which the output image data is recorded in a lengthwise or widthwise direction.

Claim 10

An image recorder as claimed in claim 5, wherein said direction changing means arranges, when the output image is rotated, the character data in positions different from positions in the input image data based on a size of said input image in a widthwise or lengthwise direction and a size of a recording medium on which the output image data is recorded in a lengthwise or widthwise direction, identifies a first blank area between consecutive character lines in said input image, and forms a second blank area of a same spacing as said first blank area between consecutive character lines of said output image data.
