Library device and logical number allocating method therefor

In a library device comprising recording/reproducing means for recording or reproducing the information using a removable recording medium, a plurality of housing means that is able to accommodate said recording medium therein, transporting means for transporting said recording medium between an optional housing unit in said housing means and said recording/reproducing means, and control means for controlling said transporting means and/or said recording/reproducing means, said respective means being accommodated in a plurality of consoles, depending on the console sorts, said consoles being combined and interconnected to permit relative positions thereof to be changed,

• a logical number allocating method comprising:
• a first step of demonstrating the relative positions of said consoles on display means and for demonstrating on said display means the locating positions of the respective console prior to change thereof by logical numbers affixed to the respective consoles;
• a second step of determining desired change positions of said consoles from said logical numbers;
• a third step of receiving the logical numbers of the consoles desired to be changed, as inputs, and allocating the logical numbers of the changed consoles based on the input logical numbers;
• and
• a fourth step of allocating the logical numbers to the respective housing sections in said changed consoles so that the allocated logical numbers of said housing sections will be contiguous to the logical numbers in said housing sections in said consoles prior to change.
