Abstract

PURPOSE: To make a beam member displaced by thermal energy of an exothermic body without allowing said body to make contact with recording liquid by providing the exothermic body to the beam member separately from the recording liquid, and by making the beam member bend by thermal energy of the exothermic body.
CONSTITUTION: A cantilever deforms suddenly from its stationary state to a state of displacement in the direction marked with an arrow by bending moment produced by expansion that is brought about by supplying of electricity to a heater 7 of a cantilever-supporting member 10. The movement of the cantilever at this time make ink inside an ink chamber 8 be ejected in the form of ink drops 12 through nozzles of a nozzle plate 11, and recording is made therewith on recording paper. In the above-mentioned process, bending by effect of thermal stress is utilized by heating (by giving thermal shock) only the surface of the cantilever that is made in a single-layer structure. It is necessary to provide the device with better radiation characteristics for improvement of recording frequency. Therefore, it is desirable to arranged the heater 7 in a liquid chamber containing insulating cooling liquid that is provided separately from the liquid chamber 8, or to make the heater 7 to be air-cooled with a fan or the like. In the case where the structure is such that the beam is supported at the opposite ends, the two heaters 7 are arranged on the supporting members on the opposite ends.
