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.

Claims

1-19. -19. (canceled)

20. A liquid container detachably mountable to a recording apparatus to which a plurality of liquid containers are detachably mountable at different positions, wherein said recording apparatus includes apparatus electrical contacts corresponding to the liquid containers, respectively, liquid container position detecting means for detecting liquid container positions in said recording apparatus by receiving light, and an electric circuit connected with a line which is commonly connected with said apparatus electrical contacts to generate a signal relating to individual information, said liquid container comprising:

ink contained in said liquid container;

a container electrical contact electrically connectable with one of said apparatus contacts;

an information storing portion storing information relating to the ink contained in said ink container;

a light emitting portion for emitting light toward said position detecting means;

a controller for emitting light of said light emitting portion when information supplied through said container electrical contact and the information stored in said information storing means correspond to each other,

wherein said container electrical contact includes a communication contact portion for communication with said recording apparatus, and a power source contact portion for supplying electric power to said light emitting portion.

21. A liquid container according to claim 20, wherein said communication contact portion includes a data signal contact for communication for controlling the emission of light of said light emitting portion and a clock signal contact.
