<p>PURPOSE:To easily perform a quality control for a large number of cassettes with a button operation, by writing a deterioration flag at the area concerned of a corresponding cassette when abnormality is generated in a reproducing picture, and performing the retrieval and the ejection of a deteriorated cassette later automatically. CONSTITUTION:By depressing a cassette ejection button 15, a control part 9 retrieves the content of a memory 8, and outputs a command to eject all of the cassettes on which the deterioration flags are attached from the output port 5 of a cassette console 3. As for an ejected deteriorated cassette, the dubbing of the content of the deteriorated cassette is performed, or when a master cassette is prepared, the same cassette is generated from the master cassette, or an action, such as the disposal of the deteriorated cassette, is performed. So that a decision for deterioration in the cassette by an automatic system, is not complete, it is desirable to use the system combined with the check, or the judgement of a monitor picture by human eyes. In such case, by providing a cassette deterioration mark button 14, or a cassette ejection button 15, a time and labor for the retrieval and the process of the deteriorated cassette can be remarkably reduced, and the quality control of the cassette can be performed skilfully.</p> |
