Title: Recording head of current supply transfer recording apparatus
Inventor: TOYOSHIMA TETSURO
IPC: B41J2/32
Filed: 1987-05-11
Abstract: PURPOSE:To reduce the generation of extraneous matter and to make said matter easy to detach by controlling the mechanical load of a recording head, by forming the backing substrate supporting a recording electrode if a resin having friction coefficient larger than that of the recording electrode having a lubricant compounded therewith. CONSTITUTION:A recording head 1 is constituted by providing a large number of arranged recording electrodes 8... on a resin substrate 6 through a heat resistant insulating layer 7 composed of a polyimide film. When a current is selectively supplied to the recording electrodes 8..., the resistance layer 2 at the current supply part generates that heat and the ink of an ink layer 3 is melted to be transferred to recording paper 4. Herein, since the fluorocarbon resin, graphite or molybdenum disulfide compounded with the resin constituting the resin substrate 6 acts as a lubricant, the friction coefficient of said substrate is set to an extremely small valve of about 0.10-0.20. Therefore, the mechanical load to the resistance layer 2 of an ink ribbon 10 is suppressed to make it possible to reduce the damage of the resistance layer 2 and the generation of the extraneous matter, which is apt to generate from the resistance layer 2, to the circumferences of the recording electrodes 8... can be reduced.
