Pattern data conversion processing system

A pattern data conversion processing system, comprising:

• first means for storing a plurality of one-character pattern data items, and for generating the one-character pattern data items according to input character codes;
• second means for generating basic pattern data items obtained by dividing a one-character pattern data item generated by said first means;
• third means for generating enlarged basic pattern data items in response to the basic pattern data items generated by said second means;
• fourth means for storing a one-character pattern data item including the enlarged basic pattern data items generated by said third means and representing one enlarged character pattern data;
• fifth means, coupled to said second, said third, and said fourth means, for controlling said second, third, and fourth means to perform the following operations:
• (i) one of the basic pattern data items generated by said second means is converted to one of the enlarged basic pattern data items by said third means;
• (ii) the enlarged basic pattern data item is written into said fourth means;
• and
• (iii) said operations of (i) and (ii) are repeated until the enlarged basic pattern data items amount to one enlarged character pattern data item, and are written into said fourth means;
• sixth means for storing one-page pattern data including the enlarged one-character pattern data items read from said fourth means;
• seventh means connected to said fourth and said sixth means, for controlling said fourth and sixth means to perform the following operations:
• (iv) each enlarged one-character pattern data item is read from said fourth means immediately after being written into said fourth means, and is then written into said sixth means;
• and
• (v) said operation (iv) is repeated until enlarged one-character pattern data amounting to one page are written into said sixth means;
• eighth means for printing one-page pattern data when read out from said sixth means;
• and
• ninth means, coupled to said sixth and said eighth means, for controlling said sixth and eighth means so that the one-page pattern data is read out from said sixth means immediately after being written into said sixth means, to be printed.
