A cassette type magnetic bubble memory comprise a bubble memory device including a bubble memory chip and lead terminals; a connector having contacts for electrically connecting the bubble memory device to an outside unit; thin flexible printed substrates for electrically connecting the contacts of the connector to the lead terminals of the bubble memory device; and a cassette case for accommodating therein the bubble memory device, the connector, and the printed substrates. The cassette case has inner walls. Some parts of the inner walls are in contact with at least some parts of an outer face of the bubble memory device to retain the device in the cassette case so that the majority of the outer face of the device is spaced from the majority of the inner walls of the cassette case. The bubble memory device and the connector are arranged in displaced positions along a plane common to the longitudinal direction of insertion of the cassette case into a bubble memory control unit.

Cassette type magnetic bubble memory

A magnetic bubble cassette including a case containing a magnetic bubble device and a connector. The cassette has a cover that is pivotably mounted by means of a support pin on the end of said case so as to permit opening and closing of the case. When the case is opened, the cassette connector can be connected to another connector provided in a cassette holder in which the magnetic bubble cassette is inserted.

Magnetic bubble cassette

A cassette type magnetic bubble memory having a magnetic bubble cassette and a cassette holder. The cassette is provided with a connector and contains within a case a magnetic bubble device comprising a magnetic bubble chip, a driving coil, a bias magnet and associated elements. The cassette holder has a cassette storing pocket and a connector to hold the magnetic bubble cassette with the corresponding connectors being connected to each other. An ejecting mechanism is provided for discharging the magnetic bubble cassette from the cassette storing pocket. An ejecting button controls the ejecting mechanism. A lid is provided in front of the cassette inlet of the cassette storing pocket. The lid is formed of a size capable of closing a cassette inlet of the cassette storing pocket and of concealing the ejecting button. The position of the lid is electrically detected.

The present invention relates to an electrical connecting device for effectuating electrical connection of a first connector unit and a second connector unit by inserting said first connector unit into the accepting port of said second connector unit. This electrical connecting device has a rotating member within said second connector unit as a coupling portion for engaging the second connector unit with the first connector unit. This rotating member rotates in combination with the inserting operation of said first connector unit, and engages with said first connector unit, pushing it in the inserting direction. In addition, the rotating member, when locked in place to secure the first connector unit, can be released by an eject button.
