A transformable toy which can be instantly transformed by merely reversibly changing its state between a horizontal state and a vertical state, without operating the toy with an intention to carry out transformation, and surprises and excites users; and an accommodating case for accommodating the transformable toy. The present invention applies a photo mask or a reticle each of which is provided with a diffraction grating pattern or with an auxiliary pattern formed of a semi-translucent film having a light intensity reducing function to a photolithography step for forming wires in an overlapping portion of wires. The controller partitions an area of the nonvolatile memory for management and numbers management information for managing data for each area and a map of the management information in an integrated manner to write the numbered management information and map to the nonvolatile memory, thereby determining whether the management information and the map are normal on the basis of the numbering. A number of storage areas are also included within the compartment including a bin formed within the hose rack. The calculating of the second parameter includes summing the particular component of the pixels of the second region.
