ABSTRACT:
A modular ink jet printer head has modules each having three spacers at their periphery in order to maintain a constant spacing between the modules. These spacers each have their base secured to the module and reside perpendicularly on a reference plane. The spacers of a module are brought into a detent engagement with at least those of one further, adjoining module. A base plate and two legs arranged at two first sides of the base plate form a U-shaped module carrier. Fastening elements for the modules are arranged at both second sides of the base plate and adjustment means are arranged at the legs. Offset stop edges for all modules are worked onto a side thereof parallel to one of the second sides of the base plate in the common opening of the base plates for the front edges of all modules. The reference edge of each module is brought into a detent engagement with an allocated stop edge of the base plate, so that a defined, lateral offset occurs between the modules.
