Abstract
An inkjet print head of an inkjet recorder is provided with a masking plate (or nozzle protecting plate), which is of such configuration as to securely protect the nozzle face against contact and collision with a recording medium and adherence of foreign matter on the recording medium, and to prevent undesired ink droplets from collecting on the masking plate (or nozzle protecting plate) or the nozzle face. The inkjet print head with an assembly of more than one nozzle is designed to be scanned over a cloth while injecting inks from said nozzles onto the cloth to form image patterns on it, and is made up of a nozzle protecting plate mounted on the print head at a given distance from the nozzle face, the nozzle protecting plate having an opening or openings formed as a path or paths for discharge of the inks. The inkjet print head of the present invention can securely protect the nozzle face against contact and collision with a recording medium and adherence of foreign matter on the recording medium to it, irrespective of the arrangement of the nozzles and the type of the recording medium used.
