Ink drop generator for ink jet printer

摘要

A drop generator for an ink jet printer comprises a mechanical vibration amplifier which is adapted, when set in vibration at one end, to cause at least one ink jet emitted from its other end to break up into drops. An electromechanical converter device is fitted at said one end to impart a vibratory movement to the amplifier when it is excited electrically. A compensating block is attached to the electromechanical converter device so as to set up in the latter a nodal vibration zone. A support member holds the generator in position in the printer and the part of the support member which is in contact with the generator is situated in the nodal zone.
