Japanese Patent Laid-Open No. 11-169549 (FIG. 7) Japanese Patent Laying-Open No. 2004-174160 (FIG. 5)

By the way, the clamp member of the above-mentioned patent documents 1 and 2 replaces a polishing belt with respect to the game island stand 100 (hereinafter referred to as the vertically installed game island stand 100) in which the ball polishing and lifting device 111 is placed vertically. There is no problem in workability at the time of play, but for the game islands 101 and 102 (hereinafter referred to as horizontal game islands 101 and 102) in which the ball polishing and lifting device 111 is placed horizontally. May cause problems in workability when exchanging the polishing belt. Specifically, when the clamp member of Patent Document 1 is attached to the ball polishing and lifting device 111 of the vertically installed gaming island base 100, as shown in FIGS. If the lifting device door 115 that opens and closes the door is opened, the pusher plate 202 faces the worker side. Therefore, the pusher plate 202 around the support shaft 203 is located at either end. As a result, it is possible to easily replace the polishing belt. Moreover, when the clamp member of patent document 2 is attached to the ball polishing lifting device 111 of the vertically installed gaming island stand 100, the lifting device door 115 is opened as shown in FIGS. 12 (A) and 12 (B). For example, since the pushing plate 212 faces the operator side, it is possible to easily remove the wing nut screwed to the bolts 211a and 211b regardless of which end the support bolt 211a is at. As a result, the polishing belt can be easily replaced.
On the other hand, when the clamp member of Patent Document 1 is attached to the ball polishing and lifting device 111 of the horizontally installed gaming islands 101 and 102, the polishing belt can be easily replaced with the lifting device door 115 opened. In order to achieve this, it is necessary to attach the pushing plate 202 so that the open side (the opposite side of the support shaft 203) is on the lifting device door 115 side. Therefore, as shown in FIG. 11C, in order to make it easy to replace the polishing belt in the horizontally placed gaming island 101 with the ball discharge port 114 facing right, the pushing plate 202 is moved from the front. It is necessary to provide the support shaft 203 at the left end when viewed. In other words, as the clamp member of Patent Document 1 in which the pushing plate 202 is provided so as to be openable and closable around the support shaft 203 with respect to the fixed plate 201, it is necessary to prepare a member that opens on the right side. However, when such a right-side opening clamp member is used in the horizontal gaming island stand 102 with the ball discharge port 114 facing leftward, as shown in FIG. 11 (D), the lifting device door 115 is opened. In this state, the support shaft 203 side (opposite side of the opening) of the push-in plate 202 faces the worker side, so that it is difficult to replace the polishing belt.
In addition, when the clamp member of Patent Document 2 is attached to the ball polishing and lifting device 111 of the horizontally mounted game islands 101 and 102, the polishing belt can be easily replaced with the lifting device door 115 opened. In order to achieve this, it is necessary to attach the pushing plate 212 that engages with the locking bolt 211b of the fixing plate 211 so that the engaging side (opposite side of the supporting shaft side by the supporting shaft bolt 211a) is on the lifting device door 115 side. There is. Therefore, as shown in FIG. 12 (C), in order to make it easy to replace the polishing belt in the horizontally placed gaming island 101 with the ball discharge port 114 facing right, the pushing plate 212 is moved from the front. It is necessary to provide the support bolt 211a at the left end of the fixed plate 211 in the viewed state. In other words, as a clamp member of Patent Document 2 that pushes the pushing plate 212 by screwing a wing nut into the support bolt 211a at one end of the fixing plate 201 and the locking bolt 211b at the other end of the fixing plate 201, the clamping member is supported on the left side. It is necessary to prepare what provided the engaging part (locking bolt 211b) on the right side while providing the shaft part (supporting bolt 211a). However, when such a clamp member of the left pivot is used in the horizontally mounted game island 102 with the ball outlet 114 facing leftward, as shown in FIG. 12D, the lifting device door 115 is opened. In this state, the support bolt 211a side (opposite side of the engaging portion) of the fixing plate 201 faces the worker side, so that it is difficult to replace the polishing belt.
Thus, according to the configurations of Patent Documents 1 and 2, when the ball polishing and lifting apparatus is placed horizontally, a right-facing one and a left-facing one are separately prepared in order to facilitate the polishing belt replacement work. Therefore, there is a problem that an increase in cost and an increase in the amount of stock of supplementary parts are inevitable for manufacturing both of the right-handed and left-handed clamping members. In addition, if two types of clamp members are transported to the installation site (amusement hall) and are mistaken, the installation work cannot be performed until the regular clamp members arrive, leading to a delay in work.
