In this pachinko machine installation island 1, a large number of pachinko machines 3 are arranged back-to-back on a support base 2, and a ball polisher 4 is provided on one side, and is provided at the upper end of the ball polisher. A ball transfer basket 6 is provided in an inclined shape in the transfer direction from the ball tank 5 so that pachinko balls lifted to the ball tank 5 flow down the ball transfer basket 6 by its own weight and are supplied to each pachinko machine 3. ing. Reference numeral 7 denotes an out-ball collecting basket provided at the inner bottom of the pachinko machine installation island 1, and the pachinko balls collected from each pachinko machine by the collecting bowl are lifted to the ball tank 5 by the action of the ball polishing machine 4. It is sent and circulates in the pachinko machine installation island.

  The ball transfer rod 6 is formed into an equal cross section in the longitudinal direction by extrusion molding of aluminum. As shown in FIG. 5 and FIG. 6 in an enlarged cross-sectional shape, the bottom plate 6a and both side walls 6b are used. An inward rib 6d is integrally formed on a hanging wall 6c which is formed in a U-shaped cross section and descends from both side edges of the bottom plate 6a. A bottom rib 6e having an L-shaped cross section is formed integrally with the lower surface of the inward rib 6d. Reference numeral 8 denotes a pachinko ball that flows down on the ball transporting cage 6, and 9 denotes an island pillar that constitutes the pachinko machine installation island 1.

  Reference numeral 10 denotes a support device according to the present invention for fixing the ball transfer rod 6 to the island pillar 9, and the support device 10 is composed of a cross beam member 11 and a fixing bracket 12 as shown in FIG. Become. The cross beam member 11 is formed by bending a sheet metal into an L-shaped cross section. Stop holes 11a are formed at both ends thereof, and a long hole 11b along the longitudinal direction is formed at the center of the upper side. A support shaft (screw shaft) 13 is inserted through the hole 11b from below. On the other hand, the fixing bracket 12 forms a horizontal substrate portion 12a and a vertical upright plate portion 12b by bending a sheet metal into an L-shaped cross section, and the support shaft 13 is screwed into a screw hole formed in the horizontal substrate portion. As a result, the fixing bracket 12 is connected on the cross beam 11 so as to be rotatable about the support shaft 13 as a rotation center. Further, the vertical upright plate portion 12b is formed in a substantially left-right symmetric shape with the support shaft 13 as the center, and downward projecting end claw pieces 12c are formed at both ends. Reference numeral 12d denotes a stopper portion extending downwardly from the vertical upright plate portion 12b to a position below the horizontal substrate portion 12a. The stopper portion abuts against the side surface of the transverse beam member 11 so that the transverse beam member 11 of the fixture 12 The upper range of rotation is limited.

  When the ball transport rod 6 is fixed in the pachinko machine installation island 1 using the support device 10, as shown in FIG. As shown in FIG. 6, the stopper 12d is in contact with the cross beam member 11 in the direction perpendicular to the ball transfer rod as shown in FIG. Rotate until As a result, the end claw pieces 12c at both ends of the fixing metal press the upper surface of the inward rib 6d to be in an engaged state. it can. In addition, according to the length of the ball transfer rod 6, a plurality of support devices 10 are fixed to the ball transfer rod 6 in advance in this manner at regular intervals. Then, the ball transfer rods 6 are arranged in a slanting shape in the pachinko machine installation island 1 as shown in FIG. 1, and the cross beam members 11 of the respective support devices 10 are arranged in the stop holes as shown in FIG. A set screw 14 is passed through 11 a, and the set screw 14 is fixed to the island pillar 9. As a result, the ball transport rod 6 can be fixed in the pachinko machine installation island 1 with an intended inclination angle at which the pachinko ball can roll under its own weight.

  The ball transfer rod 6 thus fixed is firmly fixed without being separated from the upper surface of the cross beam member 11 because the fixing fitting 12 is engaged with the inward rib 6d. For this reason, even if the pachinko ball rolls down on the bottom plate 6a of the ball transporting basket 6, the ball transporting basket 6 can withstand the heavy load of a large number of pachinko balls without causing reluctance. Moreover, since the cross beam 11 and the ball transport rod 6 can be easily fixed without the need for tools by simply rotating the fixing bracket 12 below the ball transport rod 6, a narrow space within the island 1 where the pachinko machine is installed. Work with is easy.

  Further, the support device 10 can appropriately move the support shaft 13 in the longitudinal direction of the cross beam member 11 within the range in which the long hole 11b is formed. As shown in FIG. 2, even when it is necessary to dispose the ball transport rod 6 in the width direction, it can be used without any trouble. Further, the support shaft 13 formed of a screw shaft is tightened with a screwdriver as necessary, so that the fixing bracket 12 is pulled downward, so that the end claw piece 12c can be more strongly pressure-bonded to the inward rib 6d.

  Further, the fixing bracket 12 may be manufactured by bending a relatively thin sheet metal by bending the sheet metal into an L-shaped cross section to form the horizontal substrate portion 12a and the vertical upright plate portion 12b. The rigidity of the vertical upright plate portion 12b is increased, so that it can be strongly pressed against the inward rib 6d, and a more secure fixation is possible. By bending the sheet metal in this way, a rigid fixing bracket can be easily manufactured at low cost. In addition, since the end claw pieces 12c are formed at both ends of the vertical upright plate portion 12b, the end claw pieces 12c are pressed by concentrating the upper surface of the inward ribs at one point. Can keep the state.

Further, even after the ball transport rod 6 is fixed in the pachinko machine installation island 1, the ball transport rod 6 can be easily removed by rotating the fixing bracket 12 in the opposite direction. For this reason, it becomes possible to easily perform maintenance work that cannot be performed unless the ball transfer basket 6 is temporarily removed.
