Claims

[Scope of utility model registration request]

In a printer comprising a printer unit main body disposed below a supply paper path and an openable/closable cover disposed above a supply paper route, a light emitting unit is provided on a surface of the printer unit main body facing the supply paper. and a light-receiving section are arranged with an interval between them, and a reflector is provided on the surface of the cover facing the paper supply, and the reflector is a first reflector that reflects the light beam traveling from the light-emitting section across the path of the paper supply. a reflective surface, and a second reflective surface that reflects the light beam from the first reflective surface such that the reflected light beam crosses the path of the supplied sheet again and reaches the light receiving section. A paper detection device for a printer, comprising:
