Patent ID: 7731905

Claim:
A production apparatus for producing a probe carrier by discharging plural kinds of liquids respectively containing plural kinds of probes capable of being specifically bonded to a target substance on a carrier, comprising: a liquid discharging device having nozzles for discharging the liquids respectively containing the plural kinds of probes capable of being specifically bonded to the target substance on the carrier; positioning means for determining a relative position between said liquid discharging device and the carrier, said positioning means comprising a stage for placing the carrier thereon and a first driver for moving the carrier in a secondary scanning direction parallel to a liquid-application surface thereof and substantially perpendicular to a main scanning direction; an application information detector to detect application information of the liquids discharged on the carrier on the stage from said liquid discharging device on the basis of discharge data; a defective spot detector for detecting defective spots where the liquids are not applied but where the respective liquids should have been applied by comparing the discharge data with the application information detected by said application information detector; discharge data forming means for forming discharge data as to the defective spots on the basis of defective spot information from said defective spot detector; and a processor for counting a number of redrawings, wherein said liquid discharging device executes redrawing according to the discharge data formed by said discharge data forming means by respectively applying the liquids to the defective spots on the carrier on the stage from a nozzle which is different from a nozzle that caused the defective spots, and wherein when the number of redrawings exceeds a prescribed number a message of abnormality is outputted to stop redrawing.
