Patent ID: 8573732

Claim:
A treatment-liquid application device comprising: a treatment-liquid container to store a treatment liquid; a liquid supply unit to supply the treatment liquid from the treatment-liquid container; a liquid chamber unit to store the treatment liquid supplied from the treatment-liquid container; a treatment-liquid carrier having a carrying surface movable into and out from the treatment liquid stored in the liquid chamber unit to carry the treatment liquid; a transport unit to transport an application target to an application position; a treatment-liquid applicator to apply the treatment liquid transferred from the treatment-liquid carrier, to the application target at the application position; and a partition disposed in an area of the liquid chamber unit defined by an imaginary entry plane, an imaginary exit plane, the carrying surface, and a bottom face of the liquid chamber unit, the imaginary entry plane including an entry line at which the carrying surface of the treatment-liquid carrier enters the treatment liquid stored in the liquid chamber unit, the imaginary entry plane vertically extending from the entry line, the imaginary exit plane including an exit line at which the carrying surface of the treatment-liquid carrier exits from the treatment liquid stored in the liquid chamber unit, the imaginary exit plane vertically extending from the exit line, the partition extending in a longitudinal direction of the treatment-liquid carrier perpendicular to a moving direction of the carrying surface of the treatment-liquid carrier, the partition having an edge portion adjacent to the carrying surface of the treatment-liquid carrier.
