In order to achieve the above object, in the island facility of the pachinko machine according to the present invention, the pachinko machine is installed in parallel with the frame, and the pachinko ball polishing apparatus is installed and circulated while the pachinko ball is polished by the pachinko ball polishing apparatus in the island facilities pachinko, the pachinko machine has an outer frame and the door-like front frame fixed to the frame, and the pachinko ball polishing apparatus is disposed behind the space of the pachinko machine Rutotomoni A pachinko ball transport provided with a transport section for transporting a pachinko ball discharged from the pachinko machine by winding a transport belt in a horizontal direction, a substantially horizontal direction or a direction inclined downward toward the transport direction by at least a pair of pulleys A polishing cloth unit having an apparatus and a polishing cloth for polishing the pachinko sphere transported by the transport section of the pachinko ball transporting apparatus. A pachinko ball polishing apparatus having a belt, and is configured to be detachable from the pachinko ball conveying device by sliding the polishing cloth unit, and the polishing cloth unit includes a cloth feeding unit that feeds the polishing cloth; A winding means having a cloth winding portion for winding the polishing cloth and a driving source for the cloth winding portion is attached .

In this case, the pre-Symbol Labs Migakununo unit is narrower than the inner width of the outer frame, and the upper surface of the conveyor belt of the pachinko ball polishing apparatus with the polishing pad unit is exposed polishing cloth to the lower end surface Is an open state, and when the polishing pad unit is set, the upper surface of the conveying belt and the polishing pad of the polishing pad unit may be opposed to each other.

In addition, the pachinko ball lifting unit is installed on the downstream side of the transport unit and lifts the pachinko ball transported from the transport unit, the pachinko ball transport unit is horizontal, substantially horizontal Alternatively, the working space includes a pachinko ball passage provided with a curved portion for guiding the pachinko sphere upward from a direction inclined downward toward the conveying direction and opened to the passage. An anti-back lever is disposed so as to be swingable about a swing shaft and is biased by a biasing means so as to protrude toward the pachinko ball passage side, and the working space against the bias by a conveying force of the pachinko ball. When it is pushed in, the flow of the pachinko sphere is allowed, and when it protrudes from the inner peripheral surface of the pachinko ball passage, the back flow of the pachinko sphere can be prevented .

In this case, the pre-Symbol Labs Migakununo unit is narrower than the inner width of the outer frame, and the upper surface of the conveyor belt of the pachinko ball polishing apparatus with the polishing pad unit is exposed polishing cloth to the lower end surface If the polishing cloth unit is set, the upper surface of the conveyor belt and the polishing cloth of the polishing cloth unit face each other when the polishing cloth unit is set, so that the polishing cloth unit is inserted into the pachinko machine through the outer frame. And can be installed in the pachinko ball polishing apparatus from above.
