PURPOSE:To enable a monitor means to monitor a copy means, to give an operation instruction to a collation means at aribitrarily given collating timing, to reduce time required for collation and to hold data to be the same. CONSTITUTION:An input means 50 inputs timing when the collation means 40 operates and the monitor means 60 inputs timing when the collation means 40 operates. The monitor means 60 stores timing when the collation means 40 operates and the copy means 30 copies copy source data 11 stored in a copy source storage means 10 to a copy destination data 21 stored in a copy destination storage means 20. The monitor means 60 supervises the operation of the copy means 30. When it is timing when the collation means 40 operates, the collation means 40 collates copy source data 1 to copy destination data 21. |
