れる。(3) Prior art and problems In a bubble memory cassette device, it is desirable that the bubble memory cassette can be inserted and removed while the holder unit is powered on. At the same time, the bubble memory cassette becomes operational, so the connection order of the signal line, power supply line, and ground line connecting the bubble memory cassette and the holder unit may cause malfunction of the bubble memory cassette or loss of memory. be. However, the order in which the pins of a general connector are connected is not specified at all, and when such a connector is used, the above-mentioned malfunction or memory loss may occur.

ユニツトとの接続構造である。(5) Structure of the Invention The present invention provides a structure in which a bubble memory cassette containing a built-in bubble memory chip and a holder unit including a circuit for controlling the bubble memory cassette are connected via a connector. The connector provided in the unit has a metal envelope that surrounds the connection pins of the signal line and the power line, and the metal envelope is grounded, and the bubble memory cassette and the holder unit are connected to each other. In this connection structure between a bubble memory cassette and a holder unit, the metal envelope is connected before the connection pin when the bubble memory cassette is connected to the holder unit.

ることが望ましい。(6) Embodiment of the invention FIG. 1 is a diagram showing an embodiment of the invention. In this embodiment, connector 1 on the bubble memory cassette side and connector 2 on the holder unit side are used.
Both are made of metal to form an envelope, and a ground line is connected to the metal envelope, and other signal lines and power lines are connected through ordinary connection pins.
In this case, the metal envelope is brought into contact first, and after being positioned, a normal connection pin is connected, so that the configuration of the invention described above can be satisfied. Note that it is desirable to make a notch in one side of the metal envelope so that the connection between the two is ensured by the force of the spring of the metal plate that constitutes the metal envelope.
