Abstract: PROBLEM TO BE SOLVED: To provide a terminal equipment burglar prevention system capable of detecting the disconnection of the power source of a terminal equipment or the disconnection of the connection line of the terminal equipment and a monitoring device and reporting that the terminal equipment is detached. SOLUTION: When the power source of a KARAOKE (recorded accompaniment) commander 7 is disconnected, since the DC voltage Vc of a monitoring device connection means 108 becomes 0 volt, a current is not made to flow to the photodiode of a photocoupler 202.
