ン検知機構。 1 on one side of the printing ribbon, facing the printing ribbon.
In a ribbon detection mechanism of a printing device that includes a pair of a light emitting element and a light receiving element, and detects the ribbon end by reflecting light emitted from the light emitting element by a reflecting part provided at a ribbon end and receiving the light by the light receiving element. , the other side of the printing ribbon is provided with either a second light-receiving element that receives light from the light-emitting element or a second light-emitting element that emits light that is received by the light-receiving element when the printing ribbon is not present. Ribbon detection mechanism of printing device.
