PROBLEM TO BE SOLVED: To provide a monitoring device for an inter-machine unit which can surely detect the fraudulent opening of a game machine. SOLUTION: This monitoring device 10 for the game machine is equipped with an IC (integrated circuit) tag 11 which is attached to the game machine 2, and an IC tag reader 12 which is built in a call lamp 4 as a detecting mechanism for detecting the opening of the game machine 2. Under a state wherein the game machine 2 is closed, the IC tag 11 is located in a region A being communicable with the IC tag reader 12. When the game machine 2 is opened, the IC tag 11 which is attached to the game machine 2 separates from the IC tag reader 12, and when the IC tag 11 is separated from the region A, the IC tag reader 12 becomes incapable to receive the tag information of the IC tag 11, and the opening of the game machine 2 is detected. Compared with the case using a mechanical switch or a photo-coupler, the opening/closing state of the game machine 2 can surely be monitored. COPYRIGHT: (C)2005,JPO&NCIPI
