PROBLEM TO BE SOLVED: To provide a Pachinko machine capable of improving a sensitivity of detecting a striking fraud up to a sensitivity of detecting a magnetic fraud. SOLUTION: When a magnet approaches, an N pole and an S pole are induced and reeds of a magnetic detection switch MS become a conductive state by the magnetic attraction force to detect a fraud by a magnetic fraud, and the reeds having a function as a vibration sensor, which come into contact by an external force of vibration to become a conductive state, detect a fraud by a striking fraud. The number of the magnetic detection switches MS and the number of the vibration sensors are thus regarded as the same number, so that, when a Pachinko machine 1 has a plurality of magnetic detection switches MS to broaden the detection area of a fraud by the magnetic fraud and improve the sensitivity for detecting the magnetic fraud, consequently the detection area of the fraud by the striking fraud is broadened so as to improve the sensitivity of detecting the striking fraud. This constitution can improve the sensitivity for detecting the striking fraud up to the sensitivity for detecting the magnetic fraud. COPYRIGHT: (C)2010,JPO&INPIT
