PURPOSE:To obtain a cassette type magnetic bubble memory device of good operability with which a defective connection is easily detected, by providing a cover at a cassette inserting slit to cover an ejection button and inhibiting the closure of the cover unless a cassette is completely inserted in order to inactivate a memory device. CONSTITUTION:A cover 10 is provided at a cassette inserting slit to cover an ejection button which transmits the lever function power to a slider and ejects easily a cassette C with a small power. Thus an unwilling ejection is avoided for the cassette C. A roll 41 forming a projected streak of a lever 40 is not fitted into a recess 7 of the cassette C unless the cassette C is inserted until it is connected to an inside connector 16 after opening the cover 10. thus the closure of the cover 10 is inhibited, and at the same time a microswitch 39 is not turned on. This prevents the actuation of a magnetic bubble device. Thus it is possible to obtain a cassette type magnetic bubble memory device which can detect easily a defective connection and is protected from a defect with good operability. |
