Claims

[Scope of utility model registration request]

(1) A printing device capable of printing on printing paper of any width is provided with a printing paper width detection mechanism that moves in front of the print head and the print head, and a line feed is generated based on a detection signal from the printing paper width detection mechanism. A printing device characterized by being designed to operate independently. -(2) In paragraph 1 of the claims for utility model registration,
A printing device characterized in that the printing paper width detection mechanism is constituted by a light emitting element that irradiates light onto the rotating pad surface on which the printing paper is mounted, and a light receiving element that detects reflected light from the rotating pad surface.
