Abstract
A liquid container detachably mountable to a recording apparatus to which a plurality of liquid containers are detachably mountable, wherein the recording apparatus includes apparatus electrical contacts corresponding to the liquid containers, respectively, photoreceptor means for receiving light, and an electric circuit connected with a line which is commonly connected with the apparatus electrical contacts, the liquid container includes a container electrical contact electrically connectable with one of the apparatus contacts; an information storing portion capable of storing at least individual information of the liquid container; a light emitting portion; a controller for controlling emission of light of the light emitting portion in response to a correspondence between a signal indicative of individual information supplied through the container electrical contact and the information stored in the information storing means.

20. An ink jet printer, comprising:
-
a plurality of ink containers containing inks of different colors, respectively; a holder configured to detachably hold the ink containers; an electrical contact provided in each of the ink containers; a common electrical line configured to commonly electrically connect with the electrical contacts of the ink containers held in the holder; a sending portion configured to send, to the common electrical line, individual information corresponding to respective ones of the ink containers; a light emitter provided in each of the ink containers and configured to emit light; a light receptor configured to receive the light from the light emitters; a discriminator configured to discriminate properness of positions of the ink containers in the holder, on the basis of light reception information of the light receptor; a memory provided in each of the ink containers and storing discrimination information; and a controller provided in each of the ink containers and configured to control the light emitter to emit light on the basis of the individual information received from the common electrical line through the electrical contact and the discrimination information stored in the memory. - View Dependent Claims (23, 24, 25, 26, 27)

21. An ink jet printer, comprising:
-
a plurality of ink containers containing inks of different colors, respectively; an electrical contact provided in each of the ink containers; a light emitter provided in each of the ink containers and configured to emit light; a light receptor configured to receive the light from the light emitters; a carriage which has a plurality of mounting portions corresponding to the colors of the inks contained in the ink containers, respectively, and which is movable in a moving direction so that the light receptor faces the mounting portions sequentially, wherein each of the ink containers is detachably mountable to any one of the mounting portions; a common electrical line configured to commonly electrically connect with the electrical contacts of the ink containers mounted to the mounting portions; a sending portion configured to send, to the common electrical line, individual information corresponding to respective ones of the ink containers; a discriminator configured to discriminate whether the ink containers are mounted to the corresponding mounting portions, on the basis of light reception information of the light receptor provided by light emitted from the light emitters of the ink containers containing the inks of the colors which correspond to respective mounting portions at a movement position facing the light receptor; a memory provided in each of the ink containers and storing discrimination information; and a controller provided in each of the ink containers and configured to control the light emitter to emit light on the basis of the individual information received from the common electrical line through the electrical contact and the discrimination information stored in the memory.

22. An ink jet printer, comprising:
-
a plurality of ink containers containing inks of different colors, respectively; a carriage which is movable in a moving direction and to which the ink containers are detachably mountable so that the ink containers are arranged in the moving direction; an electrical contact provided in each of the ink containers; a common electrical line configured to commonly electrically connect with the electrical contacts of the ink containers mounted to the carriage; a sending portion configured to send, to the common electrical line, individual information corresponding to respective ones of the ink containers; a light emitter provided in each of the ink containers and configured to emit light; a light receptor configured to receive the light from the light emitters; a memory provided in each of the ink containers and storing discrimination information; a controller provided in each of the ink containers and configured to control the light emitter to emit light on the basis of the individual information received from the common electrical line through the electrical contact and the discrimination information stored in the memory; and a discriminator configured to discriminate properness of positions of the ink containers in the carriage, on the basis of light reception information of the light receptor provided while different light emitters emit light as the carriage takes different positions with movement of the carriage in the moving direction.
