PLACEMENT METHOD OF SPACER

A technology for placing spacers free from the occurrence of streaks is provided. Random numbers are generated by a computer 8, and made in one-by-one association with discharge positions 11 of an object 10 for discharging every generation, and stored in a memory unit 9 of the computer 8.

Zusammenfassung:	A technology for placing spacers free from the occurrence of streaks is provided. Random numbers are generated by a computer 8, and made in one-by-one association with discharge positions 11 of an object 10 for discharging every generation, and stored in a memory unit 9 of the computer 8. Coefficient values are determined for the respective discharge positions 11 based on the stored random numbers, and individual voltage values to be required for the respective discharge positions 11 are calculated through the multiplication of voltages set for respective nozzle holes N 1 to N n by the coefficient values. When the respective voltages corresponding to the discharge positions 11 are applied to piezoelectric elements inside a discharge head 4 and a discharge liquid containing the spacers are discharged through the plural nozzles N 1 to N n provided in the discharge head 4, the spacers are placed on the object 10 for discharging by numbers according to the random numbers.
