Liquid container and liquid supplying system
First Claim
1. A liquid container detachably mountable to a carriage of an inkjet printer including an inkjet head, an electrical connecting portion and a light receptor, the liquid container comprising:
- a casing including a chamber configured to contain liquid;
a supply port provided at the casing and configured to supply the liquid in the chamber to the inkjet head;
a light emitter configured to emit light that can be received by the light receptor;
an electrical contact configured to receive control data from the electrical connecting portion; and
a controller storing discrimination information of the liquid container, and configured to cause the light emitter to emit light when the control data supplied from the electrical contact includes (a) information corresponding to the discrimination information and (b) a light emitting command code for causing the light emitter to emit light.

31. A liquid container detachably mountable to a carriage of an inkjet printer, wherein the inkjet printer includes an inkjet head, an electrical connecting portion and a light receptor, and wherein the inkjet printer is configured to determine whether the liquid container is mounted at a correct position in the carriage based on light reception information of the light receptor, the liquid container comprising:
-
a casing including a chamber configured to contain liquid; a supply port provided at the casing and configured to supply the liquid in the chamber to the inkjet head; a light emitter configured to emit light that can be received by the light receptor; an electrical contact configured to receive control data from the electrical connecting portion; and a controller storing discrimination information of the liquid container, and configured to cause the light emitter to emit light when the control data supplied from the electrical contact includes (a) information corresponding to the discrimination information and (b) a light emitting command code for causing the light emitter to emit light. - View Dependent Claims (32, 33, 34, 35, 36)

37. A liquid container, comprising:
-
a casing including a chamber configured to contain liquid, the casing having a supply port configured to supply the liquid in the chamber to an outside of the casing, the casing having a bottom wall having a supply port, a top wall opposed to the bottom wall, a plurality of side walls which are between the bottom wall and top wall, the bottom wall, the top wall and the plurality of side walls being defined by orientation when the liquid container is oriented with the supply port facing downward, the plurality of side walls including a first side wall and a second side wall which is opposed to the first side wall; an elastically deformable member having an engaging portion and elastically deformable toward the casing; a light emitter; an electrical contact; a controller (i) storing color information indicative of a color of the liquid in the chamber, and (ii) configured to control the light emitter based on (a) a control code for controlling the light emitter and color information supplied from the electrical contact and (b) the stored color information; and a substrate positioned outside the chamber and provided with the light emitter, the electrical contact and the controller, wherein the supply port is closer to the bottom wall than to the top wall and is closer to the second side wall than to the first side wall, wherein the engaging portion is closer to the first side wall than to the second side wall and is spaced from the first side wall, and wherein the electrical contact is closer to the bottom wall than to the top wall and is closer to the first side wall than to the second side wall. - View Dependent Claims (38, 39, 40, 41, 42, 43)
