Abstract

Disclosed is the use of a mechanical method for ejecting the media in a 3.5-inch diskette drive without an externally extending eject button. To insert the media, the user pushes the diskette cartridge into the slot in the diskette drive. At this point, the diskette cartridge is latched in engagement with the drive. To release the media, the user pushes the diskette inward, within the slot, a second time. At this point, the media is released for removal from the drive.

Push-Push Mechanism for Media Ejection

      Disclosed is the use of a mechanical method for ejecting the
media in a 3.5-inch diskette drive without an externally extending
eject button.  To insert the media, the user pushes the diskette
cartridge into the slot in the diskette drive.  At this point, the
diskette cartridge is latched in engagement with the drive.  To
release the media, the user pushes the diskette inward, within the
slot, a second time.  At this point, the media is released for
removal from the drive.

      This latching and releasing action can be achieved in a number
of ways.  Preferably, energy is stored within a spring mechanism as
the cartridge is inserted, to be released as the subsequent process
of media ejection is aided.  The latching and release mechanism may
be similar to a mechanism commonly used to hold a cabinet door shut
with a "push to latch," "push to release" action.  The action of
pushing the cartridge to release the media can occur with the
rotating media engaged with the spindle of the drive, since the media
is typically mounted on a center hub floating within the cartridge to
allow precise centering of the media with the spindle.

      In this way, a need to provide an outwardly-extending eject
button on the face of a diskette drive is eliminated, allowing the
development of a smaller drive, since space for the button is no
longer required.  Furthermore, the button is eliminated without
requiring the use of a compa...
