Abstract
In a printing device using m ink jets, a head for the deflection of said jets is made in modular form by the assembling of: a first plurality of elements, each comprising m electrodes, a second plurality of elements for the separation of the elements of the first plurality, that are interposed between certain elements of the first plurality to separate these elements electrically from one another; the elements of the first plurality and of the second plurality being aligned and stacked to form a compact assembly.

A modular multijet deflection head for a printing device with m parallel ink jets comprising, per ink jet, a pair of charge electrodes, a pair of phase detection electrodes and a pair of deflection electrodes, said deflection head comprising:
- a first plurality of elements, each comprising m electrodes,
- a second plurality of elements for the separation of the elements of the first plurality, that are interposed between certain elements of the first plurality to separate these elements electrically from one another;
- the elements of the first plurality and of the second plurality being aligned and stacked to form a compact assembly.
A method for the manufacture of a modular multijet deflection head for a printing device with m parallel ink jets that are deflected in a plane, wherein said method comprises the following main steps of:
- (a) manufacturing seven elements bearing the m charge electrodes, the m detection electrodes, the metal shielding layers made of identical plates of insulating material and the assembling of these elements to form a first sub-assembly;
- (b) manufacturing the elements bearing the deflection electrodes from a block of insulating material in which m metallized partitions are made to form a second sub-assembly;
- (c) assembling the first and second sub-assemblies to obtain the deflection head.
