Abstract
A liquid storing container having a liquid storing chamber for storing liquid, the liquid container includes a plurality of light-transmissive prisms for forming interfaces with the liquid or gas in the liquid storing chamber; wherein each of the prisms includes at least one surface contactable to the liquid in the liquid storing chamber, wherein each of the prisms includes a surface integral with a surface constituting a part of the liquid storing chamber, and wherein the prisms are substantially diagonally disposed in the liquid storing chamber.
Claims9
A liquid storing container having a liquid storing chamber for storing liquid, said liquid container comprising:
- a plurality of light-transmissive prisms for forming interfaces with the liquid or gas in the liquid storing chamber;
- wherein each of said prisms includes at least one surface contactable to the liquid in said liquid storing chamber,
- wherein each of said prisms includes a surface integral with a surface constituting a part of said liquid storing chamber, and
- wherein said prisms are substantially diagonally disposed in said liquid storing chamber.
A liquid container having a liquid storing chamber for storing liquid and usable in a plurality of orientations, said liquid container comprising:
- wherein said liquid storing chamber has a plurality of light-transmissive prisms for forming interfaces with the liquid or gas in the liquid storing chamber, and said prisms are disposed at respective positions corresponding to the orientations.
a recording apparatus usable with a liquid container having a liquid storing chamber for storing liquid, wherein said recording apparatus is operable in a plurality of orientations, said recording apparatus including detecting means for detecting an amount of the remaining liquid in said liquid container, said recording apparatus,
- wherein said liquid storing chamber has a plurality of light-transmissive prisms for forming interfaces with the liquid or gas in the liquid storing chamber, and said prisms are disposed at respective positions corresponding to the orientations of said recording apparatus;
- wherein said amount of the remaining liquid detecting means are disposed correspondingly to the respective prisms, and include light emitting portions for emitting light to be incident on said interfaces at predetermined incident angles, and light receiving portions for receiving the light reflected by said interfaces at predetermined reflection angles to produce predetermined detection signals, and discriminating means for discriminating whether or not a remaining amount in the liquid storing chamber reaches a predetermined level, on the basis of outputs of said light receiving portions.
