Claims

[Scope of utility model registration request]

(1) It includes a print head and a sprocket for paper feeding, and the recording paper having a guide hole for feeding is meshed with the sprocket and is intermittently fed, and the recording paper is fed by the print head at a predetermined position. A printer for printing, wherein a selected one of the guide holes is detected when a specific line of the recording paper is printed by the print head based on the relationship between the interval between the guide holes and the feed pitch by the sprocket. a logical product circuit having one input of the guide hole detecting means from the guide hole detecting means; and a microprocessor for applying as the other input of the AND circuit,
A printer characterized in that the microprocessor determines paper feed deviation of the recording paper based on an AND signal output from the AND circuit.

(2) Utility Model Registration The printer according to claim (1), wherein the guide hole detection means comprises an optical detector including a pair of a light emitting section and a light receiving section.

(3) In the utility model registration claim (1), the microprocessor has a function of supplying a stop signal to the print head and sprocket and displaying an alarm when detecting paper feed deviation of the recording paper. A printer characterized by being equipped with.
