Abstract

PURPOSE:To make it easy to observe the tips of nozzles and thereby to facilitate the inspection of discharge and the maintenance, etc., by providing cuts in a front plate for protecting the nozzles. CONSTITUTION:In a front plate 2 for protecting ink jet nozzles 4a-4d, cuts 3a-3d are provided in the places corresponding to the nozzles 4a-4d, respectively. The front plate 2 is set higher by the thickness (d) than the height of the ink jet nozzles 4a-4d. Owing to the construction as described above, each nozzle is protected well, while the tip thereof can be visually observed easily.

Description

ノズル保護の前面プレートを設けていた。Conventional technology In the past, inkjet ejection devices were equipped with a device to prevent damage to the nozzle orifice, and to prevent ink from flowing around between the nozzles and mixing colors when ejecting ink of multiple colors from multiple nozzles. (2) A front plate for protecting the nozzle was provided which was higher than the protrusion at the tip of the nozzle, as shown by reference numeral 2 in Fig. 1.

圧を決定していた。When testing the droplet ejection of an inkjet device, the speed of droplet ejection from the nozzle orifice is observed on a television screen (2) using strobe photography, and the drive voltage of the inkjet ejector is adjusted to achieve a certain ejection speed. It had been decided.

いる。In Fig. 2, the reference numeral 1 indicates a carriage for mounting an inkjet jetting device, and this carriage is driven by a motor (not shown) to the on-axis view via a timing bell (Tx, etc.). Move in the direction of the arrow shown. Reference numeral 2 denotes a front plate for protecting the inkjet nozzles 4a to 4d, and this front plate is provided with cutouts 3a to 3d at locations corresponding to the inkjet nozzles 4a to 4d, respectively.
