ABSTRACT:
A shutter locking mechanism for a FDD capable of securely keeping the shutter in opened state against any external impact. This mechanism comprises a pivot secured to the carrier for axially and rotatably supporting the shutter opening lever, and a projecting portion formed at the distal end of the shutter opening lever and fit to an aperture existing at the shutter opening lever contact side of the shutter in the loading position. The projecting portion enters the aperture at the right corner of the shutter in the loaded position while at the left corner claw portions of the stopper hold the shutter for preventing the distal end of the shutter opening lever from separating from the shutter.
