Title: Recorder
Inventor: HARA TOSHITAMI
IPC: B41J2/05
Filed: 1979-03-16
Abstract: PURPOSE:To improve thermal responsiveness in the high speed recording, discharge stability in the continuous recording and the like by arranging a heat energy generating means on the substrate having a low heat conductive thin film formed thereon. CONSTITUTION:A thin film 3 small in the heat conductivity is applied on a substrate 2 large in the heat conductivity and a heating material layer 4 and an electrode layer 5 for receiving the signal applied from outside is laminated thereon to form a heating resistor 1. When the recording signal S is inputted into a signal processing means 11 (for instance, pulse converter), the pulse-like signal leads the heating resistance 1 to generate heat to heat the recording liquid in a manner of pulse, that is a change in the state. With the change in the state, liquid drops 13 are delivered from a discharge orifice 8 and attached to the recording material to effect a recording. With such an arrangement, the heat energy is hard to transmit to the substrate at the rise of the signal applied, thereby allowing the effective generation of liquid drops.
