Abstract
A configuration for ink supply and ink disposal through connecting lines for an ink printing head has a minimum number of disposable parts, a reliable system for detecting when ink runs out, an easily adaptable coding system for individual types of ink, prevents incorrect insertion and improves servicing properties and environmental friendliness. The configuration has a cassette with a housing and two identically constructed flat boxlike containers supported in the housing. One container is intended for ink supply and the other container is intended for ink disposal. A flexible film for covering the ink is secured in the middle of each container and its size is dimensioned in such a way that the entire container volume can be utilized for the ink. A well is molded into the bottom of the container and outside it two electrodes for detecting the ink running out are fitted into the bottom and spaced apart from one another. A rubber-elastic seal for receiving an ink connecting line is inserted into a front wall of the container. Coding bores are incorporated into the front wall of the housing. Some bores are blocked while the others are open and correspond with associated coding pins in a receptacle for the cassette in the printer.
