Charging apparatus
A charging apparatus includes a plurality of holding members that holds a pair of plate-shaped members in a state the major surfaces of the plate-shaped members face each other, a movement member that causes the holding members to be moved towards and away from each other, an emission nozzle configured to be introduced into a gap between the plate-shaped members, retained by the holding members, to emit the charging liquid into the gap, a nozzle movement unit that causes movement of the emission nozzle in an in-plane direction of the plate-shaped members, a reservoir in which the charging liquid is to be accumulated, and a thrust unit that causes the charging liquid accumulated in the reservoir to be emitted via the emission nozzle.
1. A charging apparatus comprising:
a plurality of holding members that holds a pair of plate-shaped members in a state the major surfaces of the plate-shaped members face each other;
a movement member that causes the holding members to be moved towards and away from each other;
an emission nozzle configured to be introduced into a gap between the plate-shaped members, retained by the holding members, to emit the charging liquid into the gap;
a nozzle movement unit that causes movement of the emission nozzle in an in-plane direction of the plate-shaped members;
a reservoir in which the charging liquid is to be accumulated; and
a thrust unit that causes the charging liquid accumulated in the reservoir to be emitted via the emission nozzle; wherein,
the charging liquid, emitted via the emission nozzle, is charged as the liquid is contacted with the plate-shaped members carried in a relation of facing each other, and
the nozzle movement unit is configured to cause movement of the emission nozzle in at least two non-parallel directions while the emission nozzle emits the charging liquid so as to plot a preset emission pattern.
2. The charging apparatus according to claim 1 , wherein,
the holding member holds the plate-shaped member with major surfaces thereof disposed horizontally;
the nozzle having an emission opening for the charging liquid facing upwards.
3. The charging apparatus according to claim 2 , wherein,
the nozzle extends parallel to the plate-shaped member; an angle α of the emission opening being such that 30°≦α<90°.
4. The charging apparatus according to claim 1 , wherein,
there are provided a plurality of the emission nozzles; each of the emission nozzles intruding into the gap via a side of each of the paired plate-shaped members.
5. The charging apparatus according to claim 1 , wherein,
the emission nozzles are provided on one side and on an opposite side of each of the plate-shaped members; the emission nozzles intruding into the gap via the one sides and the opposite sides of the paired plate-shaped members.
6. The charging apparatus according to claim 4 , wherein,
there are provided two of the emission nozzles; each emission nozzle drawing a symmetrical shape with the charging liquid; the symmetrical shape having a thick line part extending along the longitudinal direction of the plate-shaped members and a thin line part extending from the thick line part outwardly along the transverse direction of the plate-shaped members.
7. The charging apparatus according to claim 1 , wherein,
the paired plate-shaped members, carried in a facing relation to each other, are a picture image display panel and a transparent protective panel bonded to the picture image display panel; the charging liquid being a transparent resin.
8. The charging apparatus according to claim 1 , further comprising:
curing means for curing the charging liquid charged into the gap.
9. The charging apparatus according to claim 5 , wherein,
there are provided two of the emission nozzles; each emission nozzle drawing a symmetrical shape with the charging liquid; the symmetrical shape having a thick line part extending along the longitudinal direction of the plate-shaped members and a thin line part extending from the thick line part outwardly along the transverse direction of the plate-shaped members.
