In this embodiment, a hinge shaft G64 (see FIG. 6) corresponding to the hinge shaft L3 of FIG. 1 fixed to the front lower unit hinge G6B corresponds to the hinge shaft L3 of FIG. 1 fixed to the front upper unit hinge G6A. The front upper unit hinge G6A and the front lower unit hinge G6B are the same except that they are different in that they are formed longer than the hinge shaft G63. The front lower unit hinge G6B is coupled to a hinge mounting hole (not shown) corresponding to the hinge mounting hole H62 in FIG. 3 by a set screw.
[0027]
In short, the front upper hinge G30 and the rear upper hinge H30 are fitted together, and the front lower hinge G40 and the rear lower hinge H40 are fitted together, so that the front ball dispensing unit G and the rear ball dispensing unit H having the same configuration can be obtained. Are connected to each other so as to be able to be opened. Therefore, the front ball paying unit G and the rear ball paying unit H can be used in common as a plurality of ball paying units provided at the front and rear, and the manufacturing cost is lower than when the plurality of ball paying units are formed in different forms. It becomes.
[0028]
The front ball dispensing unit G is attached to the front frame B so that it can be opened on the back side by fitting the upper and lower rear plate hinges C1 with the front upper unit hinge G6A and the front lower unit hinge G6B. Then, the rear ball paying unit H is attached to the front ball paying unit G so as to be able to open one side. Therefore, since the front ball paying unit G and the rear ball paying unit H are provided on the back side of the front frame B so as to be individually openable and closable, the front ball paying unit G is opened on the back side and the unit base of the front ball paying unit G is opened. A prize ball solenoid (not shown) corresponding to the prize ball solenoid H50 arranged between G20 and the front frame B can be exchanged.
[0029]
Further, by opening the rear ball dispensing unit H on the back side, the clogging occurring in the ball passage unit G10 disposed between the unit base G20 of the front ball dispensing unit G and the rear ball dispensing unit H is eliminated. Or the dust generated inside the passage unit G10 is removed from the working hole G13 with tweezers or the like not shown in the drawing, or the prize ball disposed between the unit base H20 of the rear ball dispensing unit H and the front ball dispensing unit G. Solenoid H50 can be replaced. That is, the maintenance work of the front ball paying unit G and the rear ball paying unit H can be easily performed by individually opening the front ball paying unit G and the rear ball paying unit H on the back side.
[0030]
Further, since the rotation center of the front ball dispensing unit G with respect to the front frame B and the rotation center of the rear ball dispensing unit H with respect to the front ball dispensing unit G are provided on the same side, the front ball dispensing unit G and the rear cover I Are connected from the front side with the front unit screw 30 and the rear ball paying unit H and the rear cover I are connected from the back side with the rear unit screw 31 to protect various control circuit boxes arranged on the back side of the game board. The rear cover I can be combined with the front ball paying unit G and the rear ball paying unit H to form the back cover unit K.
[0031]
In FIG. 6, the front upper unit hinge G6A and the front lower unit hinge G6B are fitted into the upper and lower rear plate hinges C1 from above, and the rear cover unit K is closed, whereby the rear cover receiver provided on the free end side of the rear cover I. The part I5 engages with a rear plate engaging part C3 provided on the rear plate C, and the closed state of the rear cover I is maintained.
[0032]
Since the lower hinge shaft H34; G64 is formed longer than the upper hinge shaft H33; G63, the front ball paying unit G is attached to the front frame 2 or the front ball paying out of the rear ball paying unit H. Mounting to the unit G is easy. As shown in FIG. 8a, the length of the hinge shaft P2 in the upper movable hinge P1 corresponding to the front upper unit hinge G6A and the rear upper hinge H30 is c, and the front lower unit hinge G6B and the rear side The length of the hinge axis P4 in the lower movable side hinge P3 corresponding to the lower hinge H40 is b, the distance between the hinge axis P2 and the hinge axis P4 is a, and corresponds to the upper rear plate hinge C1 and the front upper hinge G30. The distance between the hinge receiving hole Q2 of the upper fixed side hinge Q1 and the hinge receiving hole Q4 of the lower fixed side hinge Q3 corresponding to the lower rear plate hinge C1 or the front lower hinge G40 is A, and b> c, A = a Suppose that The hinge shaft P2 corresponds to the hinge shaft G63; H33, the hinge shaft P4 corresponds to the G64; H34, the hinge receiving hole Q2 corresponds to the upper hinge receiving hole C2; G33, and the hinge receiving hole Q4 Lower hinge receiving hole C2; corresponds to G43.
[0033]
Then, as shown in FIG. 8b, after the tip of the lower hinge shaft P4 is inserted into the lower hinge receiving hole Q4 from above, the front ball paying unit G and the rear ball paying unit H are lowered. As a result, the hinge shaft P4 enters the hinge receiving hole Q4. With the progress, as shown in FIG. 8c, the upper hinge shaft P2 is inserted into the upper hinge receiving hole Q2. Therefore, the insertion of the tip of the lower hinge shaft P4 into the lower hinge receiving hole Q4 can serve as a leading role, and the upper hinge shaft P2 can be inserted into the upper hinge receiving hole Q2. The length c of the upper hinge shaft P2 and the length b of the lower hinge shaft P4 can be similarly applied even when c> b.
[0034]
