An inkjet recording apparatus comprising:

• a carriage;
• an apparatus antenna;
• a light receptor;
• a liquid container detachably mountable to said carriage;
• and
• a discriminator constructed to discriminate whether the liquid container is mounted at a correct position in the carriage;
• wherein the liquid container includes:
• (A) a chamber containing a colored liquid,
• (B) a container antenna provided outside the chamber for communication with the apparatus antenna without physical contact therebetween,
• (C) an information storing portion provided outside the chamber and storing at least color discrimination information corresponding to a color of the liquid in the liquid chamber,
• (D) a light emitting portion provided outside the chamber and constructed to emit light toward the light receptor, and
• (E) a controller provided outside the chamber and constructed to receive control data including a light emitting command code and color identification information from the apparatus antenna through the container antenna, and further constructed to control light emission of the light emitting portion based on the color identification information included in the received control data and the color discrimination information stored in the information storing portion;
• and
• wherein the discriminator discriminates whether the liquid container is mounted at a correct position in the carriage based on light reception information of the light receptor provided by the light emitted from the light emitting portion.
