Abstract
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 printerhas a removable fiscal control circuit board, and mounted thereon are fiscal memory, a backup battery power supply, a real-time clock, and a detection circuitfor detecting removal of the fiscal control circuit board. The real-time clockincludes an input terminal() to which detection signals from the detection circuitare input, and a storage unitthat, when a detection signal indicating that the fiscal control circuit boardwas removed is input, stores data indicating that the fiscal control circuit boardwas removed correlated to and associated with the time when the detection signal was input.
