PROBLEM TO BE SOLVED: To provide a printer which can detect an unauthorized access by using a wiring sheet.SOLUTION: A printer 1 comprises: a memory board 15 provided with a fiscal memory 18; a wiring sheet 16 provided with first wiring 21 and wrapping the memory board 15; a memory board side RTC 42 detecting disconnection of the first wiring 21; and a flexible cable 27 connecting the memory board 15 and a fiscal control board 7. The wiring sheet 16 includes a second protrusion part 103 (sheet part) folded at a position overlapping with the memory board 15. The second protrusion part 103 includes a first slit 65 surrounded by the first wiring 21. The flexible cable 27 is routed to the outside of the wiring sheet 16 via the first slit 65. When the second protrusion part 103 is forcibly opened, the flexible cable 27 interferes therewith to break an opening edge of the first slit 65 in the second protrusion part 103 and disconnection is generated.SELECTED DRAWING: Figure 7 |
