サーマルヘツドアレイ。[Claims for Utility Model Registration] A thermal insulating layer is formed on a ceramic substrate, a linear heating resistor is formed on the thermal insulating layer, and the heating resistors are arranged at regular intervals in a direction perpendicular to the straight line of the heating resistor. A lead conductor is formed to be connected to the heat generating resistor, every other lead conductor is equally spaced and used as a ground side lead conductor and a power side lead conductor, and a wear-resistant layer is provided on the heat generating resistor and the lead conductor. In the thermal head array formed, temperature coefficients are placed on a straight line perpendicular to the straight line of the heat generating resistor in the same layer as the heat generating resistor at both ends of the straight line of the heat generating resistor. A large resistor pattern is formed, and a wiring pattern is formed to measure the temperature of each part of the resistor pattern with a large temperature coefficient by the resistance value of that part.When using a thermal head array, the above temperature coefficient is Measure the temperature of each part of the large resistor pattern, determine that the lowest temperature part is the part that contacts the recording drum of the recording device, and determine the relationship between the straight line of the heating resistor and the axis of the recording drum. A thermal head array characterized by having a means for adjusting the position.
