A fiscal printer reliably stores and holds, using a simple configuration, the date and time that a fiscal control circuit board is removed from the printer, and provides excellent security so that improper activities can be reliably discovered. The fiscal printer 1 has a removable fiscal control circuit board 4, and mounted thereon are fiscal memory 8, a backup battery power supply 11, a real-time clock 10, and a detection circuit 15 for detecting removal of the fiscal control circuit board 4. The real-time clock 10 includes an input terminal 10b(1) to which detection signals from the detection circuit 15 are input, and a storage unit 10c that, when a detection signal indicating that the fiscal control circuit board 4 was removed is input, stores data indicating that the fiscal control circuit board 4 was removed correlated to and associated with the time when the detection signal was input. |
