## Abstract

A pattern generator comprising a memory for storing a plurality of regular character and sign patterns, an input device for receiving as image data a character and sign pattern in a document, a pattern recognition unit for recognizing the character and sign pattern in the image data that the input device has received, a converter for converting the character and sign pattern recognized by the recognition into to the corresponding character and sign code, and an output device for reading from the memory a character and sign pattern corresponding to the character and sign code generated by the converter and outputting the read pattern to a recording medium.

## Claims

### Claim 1

A pattern generator comprising:
input means for receiving a character pattern of a first dot density, the character pattern existing at a designated area;
conversion means for converting the character pattern of the first dot density received by said input means into a character pattern of a second dot density;
means for setting character code data corresponding to the character pattern of the second dot density converted by said conversion means; and
means for storing the character pattern of the second dot density converted by said conversion means in correspondence with the character code data set by said setting means.

### Claim 2 (depends on 1)

A pattern generator according to claim 1, wherein said setting means includes means for inputting a code, and wherein said generator stores said image pattern in correspondence to said input code to form a new font pattern without converting the image pattern to a font pattern that said generator includes.

### Claim 3 (depends on 1)

A pattern generator according to claim 1, wherein said input means comprises an image scanner.

### Claim 4 (depends on 1)

A pattern generator according to claim 1, wherein a set of the character codes are input from a host computer.

### Claim 5

A pattern generator comprising:
input means for receiving a character pattern of a first number of dots;
conversion means for converting the pattern of the first number of dots received by said input means into a character pattern of a second number of dots;
means for setting character code data corresponding to the character pattern of the second number of dots converted by said conversion means; and
means for storing the character pattern of the second number of dots converted by said conversion means in correspondence with the character code data set by said setting means.

### Claim 6 (depends on 5)

A pattern generator according to claim 5, wherein said input means comprises an image scanner.

### Claim 7 (depends on 5)

A pattern generator according to claim 5, wherein a set of the character codes are input from a host computer.

### Claim 8

An information processing system comprising:
input means for inputting image data of a first dot density;
extracting means for extracting a character pattern from the input image data, the character pattern existing at a designated area;
conversion means for converting the character pattern of the first dot density extracted by said extracting means into a character pattern of a second dot density;
means for setting character code data corresponding to the character pattern of the second dot density converted by said conversion means;
means for storing the character pattern of the second dot density converted by said conversion means in correspondence with the character code data set by said setting means; and
output means for outputting, in response to input of code data, the character pattern stored in said storage means in correspondence with the input code data.

### Claim 9

A printer comprising:
input means for receiving a character pattern of a first dot density, the character pattern existing at a designated area;
conversion means for converting the character pattern of the first dot density received by said input means into a character pattern of a second dot density;
means for setting character code data corresponding to the character pattern of the second dot density converted by said conversion means;
means for storing the character pattern of the second dot density converted by said conversion means in correspondence with the character code data set by said setting means; and
printing means printing, in response to input of code data, the character pattern stored in said storage means in correspondence with the input code data.
