Figure 10 is a schematic left side view showing the state in which cassette C is inserted into the cassette storage chamber.
Figure a shows a state in which the cassette is not fully inserted, Figure 10b
indicates that the cassette is securely inserted. 1st
When the cassette C is inserted securely as shown in Figure 0b, the connector 3 inside the cassette is securely connected to the connector 16 on the holder side, and the roller 41 of the lever 40 is inserted into the recess 7 provided at the bottom of the cassette. insert. However, if the cassette is not inserted securely and a gap G is created between the cassette C and the connector 16 as shown in FIG.
The roller 41 cannot fit into the recess 7 because it is deviated from the position shown in FIG. The lever 40 is attached to the holder body with a support shaft 42, and the roller 41 is attached to one end of the lever 40.
is attached, and the other end extends near the lower end of the lid 10. Then, the roller 41 is moved into the recess 7 by the torsion spring 44.
It is biased in the direction of insertion. On the other hand, the lid 10 is provided with a protrusion 10a which comes into contact with the other end 43 of the lever when the cassette is not inserted securely and the roller 41 cannot fit into the recess 7, as shown in FIG. 10a. When the cassette is securely inserted and the roller 41 fits into the recess 7 as shown in FIG. can be closed to However, if the roller 41 cannot fit into the recess 7 due to incomplete insertion of the cassette, the other end 43 of the lever rises and the protrusion 10 of the lid 10
a, the lid 10 cannot be closed reliably. However, even if the lid 10 is not closed securely, if the lever 38 pressed by the operating pin 37 is restored and the signal indicating that the lid 10 has been opened stops, the control section will misinterpret this as the completion of the cassette device. and write the information,
There is a risk that reading will start.

In the figure, a slider 45 is provided with a protrusion 10b on the lid 10 and is slidably held by a holder body 15 at a position opposite to the protrusion 10b;
A lever 48 having a light shielding plate 47 at one end is provided which engages with a pin 46 formed at one end of the slider 45 and rotates about a shaft 50 as a fulcrum. The slider 45 is always connected to the holder body 1 by a torsion spring 49.
The first
As shown in FIG. 1, when the lid 10 is closed, it is pushed by the protrusion 10b and moves backward, and the light shielding plate 47 provided at one end of the lever 48 is inserted between the light emitting diode of the photo sensor 39 and the photo transistor. However, as shown in FIG. 12, when the lid 10 is opened, the slider 45 moves toward the front of the holder body 15, and the pin 46 operates the lever 48, causing the light shielding plate 47 at one end of the lever 48 to become a light emitting diode. Pull it out from between the phototransistors and remove the lid 10.
The control unit is configured to generate a signal indicating that the opening has occurred and notify the control unit.

(g) Effects of the Invention As described above, the present invention is equipped with a means for detecting the open/closed state of the lid and generating an electric signal, so that when ejecting a cassette, the lid is opened in advance and the detection signal is notified to the control unit, and the operation of the magnetic bubble device is stopped. Furthermore, since the operation of the magnetic bubble device does not start unless the cassette is installed in a predetermined position, it is possible to prevent the contents of the magnetic bubble memory from being destroyed due to an accident when the cassette is installed or removed.

1. A magnetic bubble cassette in which a magnetic bubble device consisting of a magnetic bubble chip, a drive coil, a bias magnet, etc. is assembled into a case together with a connector, a cassette storage chamber for holding the magnetic bubble cassette with the connector connected, and the magnetic bubble cassette. The cassette holder includes an eject mechanism for ejecting the cassette from the cassette storage chamber, and an eject button for operating the eject mechanism, and a lid that can close the cassette insertion port is provided on the front surface of the cassette storage chamber, and the lid In a cassette-type magnetic bubble memory device that generates an electric signal by detecting the open/closed state of A protruding pin, a lever rotatably fixed to the upper surface of the holder body, having a light shielding plate at one end and engaging the pin at the other end, and the slider suspended between the holder body and the lever. An electric signal generating means is constituted by a torsion spring that presses the light-shielding plate toward the front side, and a photo sensor in which the light-shielding plate is inserted and removed by rotating the lever between the light-emitting diode and the phototransistor that are opposed to each other. Characteristic cassette type magnetic bubble memory device.
