Abstract
An ejection head 30 is formed in a carriage 29 as inclined at an ejection angle θ1. This permits a microdroplet Fb, which is ejected from the ejection head 30, to travel in an ejecting direction J1 that is inclined at the ejection angle θ1 with respect to a normal line of the substrate 2. Thus, the position at which the microdroplet Fb is received by a backside 2b of the substrate 2, or a receiving position Pa, is brought closer to a radiating position of a laser beam B, or located offset from a nozzle position PN toward the radiating position of the laser beam B, by a first offset amount L1. This adjusts the size of a dot formed by drying the microdroplet Fb to a desired size.
Claims12
A liquid ejection apparatus comprising:
- an ejection head having an ejection port through which a liquid droplet containing a dot forming material is ejected onto a substrate;
- and
- a laser radiation device that radiates a laser beam for drying the liquid droplet on the substrate and thus forming a dot from the dot forming material,
- wherein the ejection head is oriented in such a manner that the liquid droplet is ejected from the ejection port to a radiating position of the laser beam defined on the substrate.
An identification code formation apparatus for forming a dot-matrix identification code on a substrate, the apparatus comprising:
- an ejection head having a plurality of ejection ports aligned in a direction X, each of the ejection ports ejecting a liquid droplet containing dot forming material onto the substrate;
- a laser radiation device that radiates a laser beam onto each of the liquid droplets received by the substrate so as to dry the liquid droplet and thus form a dot from the dot forming material;
- a transport device that transports the substrate in a direction Y crossing the direction in which the ejection ports are aligned;
- and
- a controller that controls the ejection head, the laser radiation device, and the transport device in such a manner as to sequentially perform ejection of the liquid droplets, radiation of the laser beams, and transport of the substrate,
- wherein the ejection head is oriented in such a manner that each of the liquid droplets is ejected from the corresponding ejection port toward a radiating position of the laser beam defined on the substrate.
