Claims

[Scope of utility model registration request]

a photo sensor that receives light projected onto the ink ribbon and outputs a signal; and a first photo sensor that determines at least whether the ink ribbon is a black ribbon or a multicolor ribbon based on the signal output from the photo sensor. What is claimed is: 1. An ink ribbon identification device comprising: a second determination device that determines the color of a multicolor ribbon;
