A registration processing section 74 is operated by the operation of the registration switch 60 to make initial registration of a magnetic force level Vs detected by a locking detecting Hall sensor 48, into a nonvolatile memory 68 together with cover opening/closing information 86 detected by a tamper switch 64 and to set unlocking and locking determination thresholds TH based on the registered magnetic force level Vs. The registered magnetic force level Vs and the cover opening/closing information 86 can be read later from the outside, and whether the initial registration of the magnetic force level is correctly made in the closed state of the cover can be confirmed.
