PROBLEM TO BE SOLVED: To recover the FPC function without replacing or repairing the FPC itself upon occurrence of disconnection of wiring on the FPC. SOLUTION: At least one wiring 2 is provided on an FPC 1 connecting between circuit boards 21 and 22, and at least one redundant wiring 3 is provided on the outside of the wiring 2. When any one of the wiring 2 is disconnected, it is replaced by the redundant wiring 3. Out of terminals 23 for connecting the wiring 2 with the circuit boards 21, 22, connection is switched by jumper connection between the connection terminal of disconnected wiring and the selected redundant connection terminal 24 of the redundant wiring portion 3. Alternatively, an I/O port is employed capable of altering assignment of the connection terminal 23 and the redundant connection terminal 24, and connection is switched by an LSI performing assignment alteration control of the I/O port such that the I/O port corresponding to the connection terminal of disconnected wiring at the wiring 2 of the FPC 1 is reassigned to the I/O port corresponding to the redundant connection terminal 24.
