GAME BOARD MANUFACTURING EQUIPMENT

PROBLEM TO BE SOLVED: To prevent an erroneous shipment of defective products in manufacturing game boards.SOLUTION: A cell film 2 with determination reference marks MK1, MK2 in black circle shapes being printed in non-transparent areas 2Ba, 2Bb where patterns are printed in non-transparent ink other than in black color, is bonded to a plate 1 made of a transparent acrylic resin from the rear side thereof so as to correspond to boss holes for attaching corner ornaments in a second quadrant and a fourth quadrant. The plate 1 made of a transparent acrylic resin in which processing of penetration parts such as boss holes H1 to H4 are completed is placed with the cell bonded face downward on a placement table M42b whose top face is painted white. Then, a quality determination is performed on the basis of an image PICa of the second quadrant corner part and an image PICb of the fourth quadrant corner part of an image PIC captured from above by a camera M42a. If a state in which a part of black color is left at positions where the boss holes H2 and H4 should exist, it is determined as "NG".SELECTED DRAWING: Figure 6 【課題】遊技盤を製造する際に不良品が誤って出荷されることがない様にする。【解決手段】第２象限及び第４象限のコーナー飾り取付用ボス孔と一致する様に、黒色以外の非透明インクで絵柄が印刷された非透明領域２Ｂａ，２Ｂｂに黒丸の判定基準マークＭＫ１，ＭＫ２が印刷されたセルフィルム２を透明アクリル樹脂製板材１の裏面側から貼り付ける。上面白色に塗装された載置テーブルＭ４２ｂの上に、ボス孔Ｈ１〜Ｈ４等の貫通部の加工が完了した透明アクリル樹脂製板材１をセル貼付面を下にして載置し、上方からカメラＭ４２ａで撮像した画像ＰＩＣの第２象限角部の画像ＰＩＣａ及び第４象限角部の画像ＰＩＣｂのそれぞれに基づいて、良否判定を実行する。ボス孔Ｈ２，Ｈ４のあるべき位置に黒色が一部が残った状態が観察された場合は「ＮＧ」と判定する。【選択図】 図６
