Abstract
The present invention relates to a print head assembly for use in an ultrasonic printer. The print head assembly comprises at least one print head which is slidably mounted in a block which is slidably secured in the ultrasonic printer. Each print head comprises an ultrasonic vibrator, a horn coupled to the ultrasonic vibrator for amplifying energy generated by the ultrasonic vibrator, and a print head wire coupled to the horn. The print head wire has a tip which forces an ink ribbon into engagement with a print medium and against a platen in the ultrasonic printer in order to print a pixel thereon. A pressurizing mechanism contacts the block and forces the tip of the at least one print head against the ink ribbon and the print medium and against the platen with a predetermined force in order to print at least one pixel on the print medium.
