PURPOSE:To produce a cassette type magnetic bubble memory device which is free from destruction of information with a simple constitution, by cover a cassette ejection button with a cover provided a casssette inserting slit and at the same time detecting electrically the open/close of said cover. CONSTITUTION:A cassette ejection button 20 is covered together with a cassette inserting slit with a cover 10 which opens and closes freely. At the same time, the open/close of the cover 10 is detected by a lever, a switch, etc. interlocking the open/close of the cover 10. Therefore a cassette is never ejected unless the cover 10 is opened, and furthermore the operation of a magnetic bubble device is discontinued by an open detecting signal of the cover 10 when the cassette is ejected. This prevents the destruction of information due to an unwilling shift of the cassette or the like. Thus it is possible to obtain a cassette type magnetic bubble memory device which is free from destruction of information with a simple constitution. |
