<p>PROBLEM TO BE SOLVED: To provide a pinball game machine capable of preventing the erroneous detection of a magnetic sensor more reliably.SOLUTION: When an ordinary ON/OFF solenoid and a distribution ON/OFF solenoid are turned on over a predetermined drive time period (opened for 28800 ms or 29000 ms), ordinary big winning port control means and distribution big winning port control means make controls to turn off an ordinary ON/OFF solenoid and a distribution ON/OFF solenoid temporarily over such an instantaneous stop time period as exerts no influence upon the drives of an ordinary ON/OFF door and a sharing ON/OFF door. Moreover, the abnormality decision means decides the presence and absence of the abnormality in response to the magnetic detection signal sent from the magnetic sensor, at the stopping time when the big winning port control means and the distribution ON/OFF solenoid are turned off and at the instantaneous stop time of the aforementioned drive time, the presence or absence of the abnormality is decided by receiving the magnetic detection signal sent from the magnetic sensor.</p> |
