Claims

[Scope of utility model registration request]

In a printer configured to perform marking by a print head of a print carrier that reciprocates along a printing surface, and in which the print carrier is provided so as to be positionable in an approach state, an escape state, and a ribbon exchange state,
A blank printing prevention mechanism for a printer, characterized in that a detection means is provided for directly detecting the second position when the printing carrier is in an approach state, and printing is performed when the detection means is sending out a detection signal. .
