Abstract
A roll thermosensitive recording material is wound about a winding core, which has a hole code disposed in an end surface. The end surface has a black color. The hole code includes plural holes formed in the end surface at a regular depth, and has a hole base face with a white color. In a code reader, a code detecting photo sensor is set so as to adapt a detection distance thereof to the hole base face, and detects the white color from the hole base face, to read the holes. A code inspecting photo sensor is set so as to adapt a detection distance thereof to the end surface, for inspecting the end surface. The winding core is detected unacceptable if the code inspecting photo sensor detects the white color from the end surface.
