Title:
LIQUID STORAGE CONTAINER
Document Type and Number:
WIPO Patent Application WO/2014/132614
Kind Code:
A1
Abstract:
In conventional liquid storage containers, it is difficult to improve detection accuracy of the remaining quantity of liquid. This liquid storage container is characterized by being provided with: a first electrode (61A) and a second electrode (61B) which pass from an outer side of a storage part capable of storing ink (75), to an inner side of the storage part, and which extend in a direction intersecting a vertical direction; and a support part (63) which is provided inside the storage part, and which supports the first electrode (61A). The liquid storage container is further characterized in that: the height of the second electrode (61B) in the vertical direction, relative to the first electrode (61A), is equal to that of the first electrode (61A), or less than that of the first electrode (61A); the support part (63) is provided with a support wall (64) which supports the first electrode (61A), and a side wall (65) which intersects the support wall (64) and extends vertically downward from the support wall (64); and the support wall (64) is formed, at a second-electrode (61B) side of the first electrode (61A), so as to be capable of protruding further towards the second-electrode (61B) side than a meniscus (91) formed in the ink (75) between the first electrode (61A) and the support wall (64).
