<p>PURPOSE:To provide a gradated recording method executing a current passage in response to a bit which is different at every block of a plurality of blocks of a heat generating body of a thermal head. CONSTITUTION:A plurality of heat generating bodies R of a thermal head 1 are divided into two or more blocks B1 to B4. And, a current passage in response to a different bit at respective block is executed. This makes a continuation time of a maximum electric current short and realizes a small size of a capacity of an electric source and so on.</p> |
