Abstract:
1. An inkjet printing apparatus, comprising: a light receptor; an ink container; a carriage including a plurality of mounting positions to which the ink container is detachably mountable, wherein one of the mounting positions is a correct mounting position for the ink container, and wherein the carriage is configured to move relative to the light receptor so that the correct mounting position faces the light receptor; apparatus electric contacts corresponding to the mounting positions, respectively; and a common electrical line commonly electrically connected with the apparatus electric contacts, wherein the ink container includes: (i) an electrical contact electrically connectable with one of the apparatus electric contacts when the ink container is mounted at one of the mounting positions; (ii) a light emitter capable of emitting light toward the light receptor; (iii) an information storing portion storing container discrimination information that indicates a color of an ink in the ink container; and (iv) a controller configured (iv-i) to receive color information and a command from the common electrical line via the electrical contact and the one of the apparatus electric contacts, (iv-ii) to turn on the light emitter if (a) the received color information corresponds to the container discrimination information stored in the information storing portion and (b) the received command is a turn-on command for turning on the light emitter, and (iv-iii) to turn off the light emitter if (a) the received color information corresponds to the container discrimination information stored in the information storing portion and (b) the received command is a turn-off command for turning off the light emitter, wherein the inkjet printing apparatus further comprises a discriminator configured to discriminate whether the ink container is mounted at the correct mounting position, using light reception information of the light receptor when (a) the light emitter emits the light and (b) the correct mounting position faces the light receptor.
