ABSTRACT:
The present invention provides a printing device wherein a sublimable dyestuff contained in a dyestuff case is heated to sublime to form steam of the dyestuff into which gas is flowed in order to pressurize the dyestuff steam to form pressurized dyestuff steam. A nozzle plate having a nozzle formed therein for jetting the pressurized dyestuff steam toward a record medium is communicated in a closing up relationship with the dyestuff case, and a valve for opening and closing the nozzle is provided at a deformable portion of a valve beam. An electrode plate is provided in an opposing relationship to the valve and in an isolated relationship from the valve and the pressurized dyestuff steam. The valve is displaced by an electrostatic force caused by a difference in potential between the valve and the electrode plate to close the nozzle. By selectively opening the nozzle, the pressurized dyestuff steam at a high pressure is jetted from the nozzle to effect printing.
