PROBLEM TO BE SOLVED: To provide a power supplying device of a ball lifting device, capable of reliably protecting the whole operating part of the ball lifting device on a pachinko game machine island from abnormalities such as invasion of foreign matters and capable of reliably informing the abnormalities just after occurrence. SOLUTION: A current value of a motor 78 of a ball shooting device 33 is detected by a current converter 82, the state of detected load is compared with a judging reference value (an overload reference value and the overload allowable time) by an overcurrent detecting circuit 83 and an output circuit 86 to judge the overload (abnormalities). When overload is judged, an electromagnetic shut-off machine 81 is operated by functions of a relay 88 and a signal input part 89 to shut off power supply to the motor 78. A judging reference value can be optionally adjusted in a specified range by functions of a time value adjusting circuit 87 and a current value adjusting circuit 84.
