PURPOSE:To make it possible to protect collected data in a complete state by storing the operation of a control part in a non-volatile memory part at a time when a power supply part is turned off and restoring the stored operation state in an arithmetic control part when the power supply is turned on and recovering the original operation. CONSTITUTION:Arithmetic control part 13 accepts inputted data and performs a prescribed operation on a basis of this data and stores the result in non-voltile memory part 14 and supplies the operating power from power supply part 15 to control part 13 and memory part 14. Then, memory part 14 stores the operation state of control part 13 at a time when power source part 15 is turned off, and further, restores the stored operation state to control part 13 when power supply part 15 is turned on and the original operation is recovered. Thus, even if the power supply is turned off in arithmetic operation, collected data can be protected in a complete state without collapse. |
