[0171] (Overall structure of liquid ejecting equipment)
[0172] Next, a liquid ejecting apparatus 10 as an embodiment of the present invention will be described with reference to FIGS. 11-14C. FIG. 11 is a block diagram schematically showing the structure of the liquid ejection device 10 .
[0173] The liquid ejection apparatus 10 includes a carrier K, a liquid ejection mechanism 50 for ejecting charged solution droplets on the carrier K, a thermostat 41 for accommodating the liquid ejection mechanism 50 and the carrier K on which the ejected droplets land, air Regulator 70, which serves as a unit for regulating the spraying environment, for regulating the temperature and humidity of the environment inside the thermostat 41, an air filter for filtering dust in the air circulating between the thermostat 41 and the air conditioner 70 42, a differential pressure gauge 43 for detecting the pressure difference between the inside and outside of the thermostat 41, a flow control va...

[0270] Refer below Figure 18 The liquid ejection mechanism 101 according to the second embodiment of the electrostatic attraction type liquid ejection apparatus is explained. Figure 18 It is a schematic diagram showing main parts of the liquid ejection mechanism 101 . The nozzle 51 is shown facing downward in the same manner as in actual use. Among them, the same elements as those of the above-mentioned liquid ejection mechanism 50 are denoted by the same reference numerals, and their repeated descriptions are omitted.
[0271] It is assumed that the liquid ejection mechanism 101 is not used within the thermostat 41 which can be set to a suitable dew point, unlike the liquid ejection mechanism 50 described above. Therefore, the liquid ejection mechanism 101 suppresses the influence from the uneven potential distribution on the surface of the carrier using a method different from that used in the liquid ejection mechanism 50 .

[0294] Refer below Figure 20 A liquid ejection mechanism 201 according to a third embodiment of the electrostatic attraction type liquid ejection apparatus will be described.
[0295] (the difference)
[0296] Such as Figure 20 As shown, the liquid ejection mechanism 201 is used outside the thermostat 41 as in the liquid ejection mechanism 101 , and includes the liquid ejection head 56 , and an ejection voltage applying unit having a charging unit 204 . The liquid ejection head 56 has the same structure as that of the second embodiment, but the ejection voltage applying unit having the charging unit 204 is different from that of the second embodiment. While the ejection voltage applying unit having the charging unit 104 applies a stable voltage in the second embodiment, the ejecting voltage applying unit having the charging unit 204 applies a pulse voltage in the third embodiment.
[0297] The ejection voltage applying unit having the charging unit 204 includes a stabiliz...
