概要

論文の詳細を見る
A high-efficiency thermal printing head with a resolution of 16 dot/mm has been developed. Print power efficiency was remarkably improved by using polyimide which has low thermal conductivity and high temperature stability, as a heat-resistant layer. The thickness of the polyimide layer was optimized to ensure both high efficiency and rapid cooling by temperature response analysis of the head using the finite-element method. Experiments show that the printing power for thermal paper decreased to half of that of conventional heads with glass glaze, and the pulse durability of the head exceeded 10^8 pulses within an electric resistance change of 10%.
