ABSTRACT:
An ink leaking from an atmosphere communication hole of a waste ink container is guided to an end portion of the waste ink container. Electrodes are provided for shutting off an ink guide path. By this, the ink leaking through the atmosphere communication hole is inherently guided into the end portion of the container to come into contact with both of the electrodes. By contacting of the ink, a resistance value between the electrodes is varied to permit detection of ink leakage based on the variation of the resistance value. As a result, ink leakage from a waste ink container employed in an ink-jet printer or so forth can be certainly detected. Also, sealing ability of the waste ink container can be enhanced.
