SOLUTION: A detection means 31 detecting that each cover body 4 is brought into the closed position is installed for each cover body. When a locking instruction is given to the electric locking device, if the detection means does not detect the cover closing of the cover body, an error is displayed by an error display means 22b. Thus, the non-closed cover body can be easily detected without confirming the cover closed position of the cover body 4 beforehand. COPYRIGHT: (C)2006,JPO&NCIPI
