PURPOSE:To prevent a cassette type magnetic bubble memory device from malfunction with a simple constitution by generating ON and OFF signals through a douser according with a slider interlocking with the opening/closing of a lid. CONSTITUTION:When a cassette is inserted incompletely and the lid 10 of a cassette insertion port is not closed, the slider 45 to be locked by a projection 10b of the lid 10 is slided, a lever 48 is oscillated by a pin 46 and the ON/OFF state of an electric signal from a photosensor 39 is switched through the douser 47 fitted to the leading end of the lever 48. Therefore, power is not supplied to the cassette type magnetic bubble memory device until the cassette is completely loaded and the lid 10 is completely closed, so that the memory device is prevented from malfunction with a simple constitution. |
