出手段を備えであるインクリボン障害検出装置。[Claim for Utility Model Registration] In a printing device having an ink ribbon that runs horizontally along the printing position, a conductor is attached to the upper and lower ends of the ink ribbon, and the conductors are attached to both sides of the ink ribbon so as to be in contact with the ink ribbon. A pair of conductors are provided on each side so as to cover the entire printing area of the ink ribbon, and if the ink ribbon is bent or lifted, the conductor at the top or bottom end of the ink ribbon may be connected to the conductor, and either of the conductors provided on both sides of the ink ribbon may be connected. An ink ribbon failure detection device comprising detection means for generating an abnormal signal when one or both of the conductors are short-circuited.
