A is solved by a magnetic bubble cassette holder characterized in that it is provided with interlocking means for interlocking the lock release buttons 23 and 33 with the operation of fitting into the lock pawl fitting recess 6.

[Effect]

According to the above means, the operation of the lock release buttons 23, 33 is linked to the operation of the lock pawls 22, 32 that fit into the lock pawl insertion recess 6. Therefore, by detecting the operation of the lock release buttons 23 and 33, it is possible to easily confirm whether the magnetic bubble cassette 1 is completely inserted or incompletely inserted, and the magnetic valve cassette is inserted based on the confirmation information. By driving the internal magnetic bubble memory device, damage to stored information due to incomplete insertion has been eliminated.

〔Example〕

The magnetic bubble cassette holder according to the present invention will be explained below with reference to the drawings.

Fig. 1 is a partially cutaway plan view of a cassette 1 mounted on a holder which is an embodiment of the present invention;
The figure is a plan view for explaining the process of attaching the cassette 1 to the holder shown in FIG. FIG.

In FIG. 1, in which the same reference numerals are used for parts common to those in FIG. Lock claw 2 that fits into
The tip end portion 22a of 2 is provided in a protrusive window.
A rocking pawl 22 supported by the fixed shaft 10
The torsion coil spring 12 constantly urges the tip end 22a toward the cassette insertion hole. Further, an inclined surface 22b is provided in the intermediate portion of the lock pawl 22 in a direction opposite to the protruding direction of the tip portion 22a, and an end surface 22c is formed which is located behind the inclined surface 22b and faces the inclined surface 22b. .

The lock release button 23 is accessed from the front by the operating section 23a.
The insertion portion 23b of the return spring 15 and the shielding portion (rear end portion) 23c are integrated in the shape of a shaft, and an inclined surface 22b and an end surface are provided between the operating portion 23a and the insertion portion 23b. A protruding pin 24 is installed between the pin 22 and the pin 22c.

Therefore, in order to attach the cassette 1 to the holder 21, when the cassette 1 is inserted into the cassette insertion hole of the holder 21, as shown in FIG.
The lock pawl 22, whose tip 22a protrudes toward the side surface of the lock pawl 22 is pushed, rotates in the outward direction shown by arrow B.
The protruding end comes into contact with the side surface of the cassette 1 and maintains that position. At this time, since the inclined surface 22b pushes the pin 24 backward during the rotation, the lock release button 23 retreats, and the tip of the shielding part 23c comes to interrupt the optical path of the photointerrupter 17.

Then, the insertion is continued further and the lock claw 22 is
When the tip 22a of the locking claw 22a is fitted into the recess 6 by the repulsive force of the torsion coil spring 12, the locking pawl 22 rotates in the direction opposite to arrow B as shown in FIG. The lock release button 23 moves forward together with the inclined surface 22b due to the repulsive force of the coil spring 15, and the tip of the shielding part 23c comes to open the optical path of the photointerrupter 17.

Therefore, the peripheral circuit of the magnetic bubble memory device housed in the cassette 1 is configured to operate upon receiving the opening signal from the photointerrupter 17, and confirms that the tip end 22a is completely inserted into the recess 6. It will be driven from.

In FIG. 3, in which the same reference numerals are used for parts common to those in FIG. Lock claw 3 that fits into
A window is provided through which the tip end portion 32a of 2 can protrude.
A rocking claw 32 supported by the fixed shaft 10
The tip portion 32a protruding toward the cassette 1 is always urged toward the cassette insertion hole by the torsion coil spring 12. In addition, the lock claw 32
A groove 32b is formed in the middle portion of the groove 32b in a direction opposite to the protruding direction of the tip portion 32a.

The lock release button 33 is accessed from the front by the operating section 33a.
The insertion portion 33b of the return spring 15 and the shielding portion 33c are integrated in the shape of a shaft, and a pin that slidably fits into the groove 32b is provided between the operating portion 33a and the insertion portion 33b. 34 have been planted. Therefore, the rotation of the lock claw 32 is linked to the back and forth movement of the lock release button 33, and as a result of this linkage, when the lock release button 33 is moved backward, the shielding part 33c blocks the optical path of the photointerrupter 17. The shielding part 3 when the lock release button 33 moves forward due to this interlocking action.
3c opens the optical path of the photointerrupter 17.

Therefore, when the cassette 1 is inserted into the holder 31, the lock release button 33 operates in the same way as the lock release button 23, and a signal indicating that the cassette 1 has been completely inserted is output from the photointerrupter 17, so that the cassette 1 is inserted into the holder 31. The signal makes it possible to drive the magnetic bubble memory device within the cassette 1.

[Effect of idea]

As explained above, according to the present invention, it is no longer necessary to drive the magnetic bubble memory device in the state of incomplete insertion, and the practical effect of eliminating the conventional information destruction caused by incomplete insertion is extremely large.
