ABSTRACT:
A storage medium disk driving apparatus of a first embodiment includes a rotary plate including a centering section and a recessed section, a fixing plate received in the recessed section and having a proximal end portion pivotally attached to a peripheral portion of the rotary plate, and an engaging projection formed on a distal end portion of the fixing plate and having an inclined surface formed on a distal side portion thereof. When elastic deformation of the fixing plate is caused by pressing its distal end portion, the inclined surface moves so as to extend in parallel to the rotary plate. The apparatus of a second embodiment includes a protector plate fixed in parallel to the rotary plate to thereby cover the rear side of the rotary plate.
