Abstract: A nonvolatile memory and a data rewriting method of the nonvolatile memory that can readily detect a state of operation at a time of a system failure due to a power failure or the like and quickly and reliably restore the nonvolatile memory to a normal storage state by a simple method. In the nonvolatile memory including a physical block as a storage unit, the physical block having a data area (1) and a redundant area (2), the redundant area (2) includes: a logical block address storing area (3) for storing an address of a corresponding logical block; a previously used physical block address storing area (4) for storing an address of a physical block to be erased; and a status information storing area (6) for storing status information for distinguishing a state of operation in each stage occurring in performing data rewriting operation on the physical block.

Abstract: A roll film connecting device comprises means for transporting a preceding film and a film following the film via a connecting station, a pair of connecting members arranged at the connecting station and movable toward or away from each other with a film transport path positioned therebetween, each of the connecting members having a face opposed to the other and serving as a suction face, a pair of cutters so arranged as to be movable out of or into the respective suction faces of the connecting members, and a cutter receiver so disposed as to be movable into or out of a space between the connecting members as moved away from each other.
