Claims

[Scope of utility model registration request]

The ink ribbon is placed between the printing hammer and the platen.
In an impact printer, a ribbon separator is attached, paper is placed between the ribbon separator and the platen, and the print hammer and platen are hit to make the ink from the ink ribbon adhere to the paper, while the paper is moved by the paper feed mechanism to perform printing. a platen moving mechanism that moves the ribbon separator and the gap in the direction in which they are spread; a detecting means that detects that the amount of paper feed has exceeded a certain number of lines; A platen opening/closing control mechanism comprising: an electric drive means for moving in a direction to widen a gap between an ink ribbon and a ribbon separator located between an ink ribbon and a sheet of paper;
