Abstract

PURPOSE:To enable drops of ink to be formed at wide driving frequencies and at a low voltage by setting the distance between a pressure applying means and a connecting hole at a special range. CONSTITUTION:The distance (l) of a pressure applying means 4 to a connecting hole 5 is set so that (2m-1)/(4l)<=fm<=mc/(2l) (m takes a positive integer) is satisfied with the frequency fm of a signal to drive a pressure applying means (piezo element etc.) 4 and an ink pressure transmitting speed C. The threshold of jet of ink drops in a high driving frequency can be released and low voltage drive can be conducted in the range of practical frequencies about 20-100kHz.
