Fig. 2 is an exploded perspective view of the floppy disk drive device equipped with the accidental erasure prevention mechanism according to this invention, Fig. 3 is an assembled perspective view of the same with the disk cartridge inserted, and Fig. 4 is the disk cartridge pushed in. FIG. 2 is an assembled perspective view of the device in a state where it is attached to the main body of the device.
FIGS. 5A and 5B are perspective views showing an enlarged switch member portion of the disk cartridge;
A is when the switch member is in the erasable position, B
indicates that it is in a non-erasable position. FIG. 6 is a longitudinal cross-sectional view along the length of the detection member, showing the erroneous erasure prevention mechanism. 7 and 8 show a conventional erroneous erasure prevention mechanism, with FIG. 7 being a perspective view of the detection mechanism, and FIG. 8 being a partially sectional side view illustrating its operation.

Claims

[Claims for Utility Model Registration] The disk cartridge is provided with a switch member that is movable between an erasable position and a non-erasable position, and the device body to which the disk cartridge is installed is provided with a switch member that can move between an erasable position and a non-erasable position. The detection member is integrally formed with a single plate spring member having a detection part that detects the position of the switch member when the disk cartridge is attached, and a shutter part that opens and closes the detection sensor. A mechanism to prevent accidental erasure of disk drives.
