Title: Electrostatic removal method and device for game machine such as pachinko machine
Inventor: MORI TOSUKE
IPC: H05F3/04
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To remove electrostatic charge on the whole unit effectively by allowing the ions, which are generated with discharging by a discharge electrode, to blow into each island unit of pachinko machines. SOLUTION: A plurality of blower fans 1 are installed at a certain spacing in the upper part of the managing space 23 of each island unit 20 of pachinko machines. When a high voltage is impressed on a discharge electrode installed on the case of each blower fan 1, an electric discharge occurs to generate ions. This causes all fans 1 to send out ion winds downward simultaneously. The ion winds pass through the gap at the rear of the islands 20a and 20b and intrude to a pachinko machine 21 and ball paths, and therefore, the static charge on the whole islands 20a and 20b on both sides can be discharged effectively, including all pachinko machines 21.
