ツト印字ヘツド。[Claims for Utility Model Registration] A printing wire is driven by energizing a drive coil under the control of a control device of the printer body to perform printing, and a means for detecting the head temperature is provided to output the temperature detection signal. In the wire dot print head that sends out data to the control device, the head temperature detection means is composed of a temperature detection element and a temperature detection circuit, and the head temperature reaches the upper limit head temperature based on the detection result of the temperature detection element. A wire dot print head characterized in that a high temperature alarm signal is sent as a temperature detection signal from the temperature detection circuit to a control device of the printer main body.
