       This article describes a device which automates the
locating of a stored 3.5-inch floppy diskette, the checking of the
status of a file-protect switch of that diskette, and the changing of
the status of this file protect switch, if desired.  The attributes
of this device would be useful to handicapped individuals.

      Fig. 1 shows a floppy-diskette storage carousel device 1
holding a plurality of 3.5-inch diskettes 2.  Each of the diskettes
is bar-coded on an end edge for identification purposes.  Each
diskette fits into a groove on the carousel. The front of each groove
is angled for easier insertion of the individual diskettes.  A RS232
cable 3 connects the storage carousel with a personal computer, which
is used to control the activities of the storage carousel.  A
carousel unit 4 rotates about its base by means of a stepper motor 5.
This stepper motor has the same number of discrete steps per
revolution as the number of floppy diskettes in the carousel unit.

      When a user desires a particular diskette, he would enter a
command at the keyboard of his personal computer for this particular
diskette.  In Figs. 2 and 3, a bar-code reader 11 would scan the
bar-coded diskettes until the desired one is located and positioned
for removal from the storage carousel.

      Before the desired diskette is ejected, it is retracted
radially inwards by a gripper 13 and the position of the file protect
switch is opti...
