To describe the operation of this embodiment having such a configuration, first, the eject button 7 of the cassette device 1 is operated to open the cassette storage lid 2 covering the cassette storage opening 1b to the front. Next, insert the floppy disk 11 with the floppy disk 12 stored in the holding frame 2a from above in a predetermined direction, that is, when viewed from the front, so that the opening/closing lever 16 protrudes above and to the right of the cassette storage lid 2. and hold it. Next, when the cassette storage M2 is closed, the upper arm 2c and the lower arm 2d are guided by the arm guide inside the cassette device 1, and at the same time, the opening/closing lever 16 protruding upward and downward of the cassette storage lid 2 is operated. Each lever 13 has an upper notch 3. Passing through the lower notch 4 without contacting the panel 1&, the cassette storage lid 2 covers and closes the cassette storage opening 1b, and the floppy disk 11 is stored in the cassette device 1.

Next, by operating the ejecting mechanism inside the cassette device 1, the opening/closing lever 16 and the operating lever 13 are operated to eject the floppy disk 12 through the entrance/exit 11a of the floppy cassette 11 and load it into the disk drive mechanism. After this, data reading and writing operations will be performed using the floppy disk.

The above is the operation when the floppy cassette 11 is correctly held in the holding frame 2a of the cassette storage lid 2 as specified, but an operator who is not accustomed to operating the cassette device 1 may not hold the floppy cassette 11 correctly. The following is a case in which the operating lever 13 (
The cassette storage lid 2 cannot be closed because opening and closing the lower notch 4 provided in the small case does not allow 8-16 to pass through.
The operator will notice the erroneous operation. In addition, if the left and right direction of the floppy power set is reversed by mistake, the opening/closing lever 16 and the operating lever 8-13 will protrude to the upper left of the cassette storage lid 2 and to the left on one side, so the cassette storage lid 2 When closing the chain, there is no notch on the panel surface, so the chain contacts and becomes impossible to open.

As mentioned above, the present invention has been described using one embodiment, but within the scope of the gist of the present invention, for example, a flowchart may be used.

For example, by providing a notch in the beaker set and a protrusion that matches the notch on the holding frame or panel, or by providing four parts on the bottom of the holding frame that fit only one lever, it is possible to Various modifications can be made to ensure this, and these are not excluded from the scope of the present invention.

(Effect of N Light) As explained in detail above;;C, the present invention requires that the floppy cassette be held in a predetermined regular direction by the holding frame provided on the cassette storage lid when loading the floppy cassette into the cassette device. ,
Since the cassette storage lid cannot be closed, the operator can be alerted to the fact that the operation is erroneous. Since the erroneous operation can be seen at a glance from outside the cassette device, it can be corrected immediately, reducing time loss.Furthermore, since the floppy cassette is not inserted inside the cassette device, errors caused by the ejection mechanism inside the cassette device, etc. Accidents such as bending or damaging floppy disks can be completely prevented6.
