制御することを特徴とする請求項第１項に記載の
ワイヤドツトプリンタ。[Claims for Utility Model Registration] (1) A wire dot printer that drives a wire by energizing a drive coil, comprising a detection means for detecting a terminal voltage of the drive coil when energized, and a detection means based on the detected terminal voltage. 1. A wire dot printer comprising: a time control means for controlling the energization time of the drive coil, the time control means making the input power per operation of the drive coil constant. (2) The time control means holds a standard energization time at a standard terminal voltage, and the standard energization time and the energization time are inversely proportional to the ratio of the standard terminal voltage and the detected terminal voltage. 2. The wire dot printer according to claim 1, wherein the energization time is controlled accordingly.
