Further, at this time, the operating rod 95 is maintained in the upward moving state by the pins 95a and 95b coming into contact with the outer peripheral edges of the engaging members 80a and 80b. When the front frame 70 is closed in this latched state, the engaging pieces 63a and 63b enter the engaging grooves 80c of the engaging members 80a and 80b and rotate the engaging members 80a and 80b upward, as shown in FIG. As described above, the engaging pieces 63a and 63b are engaged with the engaging grooves 80c, the latch pins 95a and 95b are engaged with the locking grooves 80d of the engaging members 80a and 80b, and the operating rod 95 moves downward. Therefore, the front frame 70 is locked in the closed state by returning the key to the original rotating state and removing the key from the cylinder lock 79.

An upward protrusion 86 is fixed to the upper portion of the vertically long plate 90 via a fixing member 86a, and the upward protrusion 86 projects to the back surface of the front frame 70 so as to face the guide member 64. Therefore, when the front frame 70 is closed, the upward protrusion 86 rides on the guide member 64 so that the heavy front frame 70 is easily closed to the housing 40. An elastic protrusion 87 is provided on the back upper edge of the front frame 70 so as to come into contact with the front surface of the game board 2 when the front frame 70 is closed.

Further, by inserting a key into the cylinder lock 79 of the front frame 70 locked in the closed state to rotate the rotating piece 91 and moving the operating rod 95 upward against the elasticity of the tension springs 96a and 96b, the latch pin 95a, Since the 95b is pulled out from the lock groove 80d, the engaging members 80a and 80b become rotatable, and by pulling the front frame 70 forward in this state, the engaging pieces 63a and 63b are pulled out from the engaging groove 80c and the front frame The 70 can be opened, and when the front frame 70 is opened, the latch pins 95a and 95b come into contact with the outer peripheral edges of the engaging members 80a and 80b as described above, so that the operating rod 95 is prevented from moving downward. It is maintained in an upward motion state and latched. In short, the unlocked state of the locking device 78 is maintained even when the key is released. A tab 95e for interlocking, which will be described below, is bent and formed at the lower end of the operating rod 95, and an engaging hole 95f is provided in the tab 95e.

Next, the configuration of the entrance shutter device 100 shown in the exploded perspective view of FIG. 14 will be described. The entrance shutter device 100 is provided at the ball inlets 84a and 84b of the front frame 70, and the shutter member 100a is movably provided inside the box-shaped body 101 having the ball inlets 84a and 84b formed on the upper portion thereof. At the same time, the base end portion 102a of the transmission rod 102 is rotatably supported in the box-shaped body 101, and the tip of the pin 102b projecting from the substantially intermediate portion of the transmission rod 102 is engaged with the shutter member 100a. At the same time, the short shaft portion 102c formed at the other end of the transmission rod 102 is loosely fitted into the engagement hole 95f of the tab 95e. 103 and 104 indicate a lid body screwed to the box-shaped body 101. Further, when the interlocking pin 100b is fixed to the shutter member 100a, the interlocking pin 100b is projected from the notch portion 104a formed in the lid body 104, and the front frame 70 is closed, the tip portion of the interlocking pin 100b is said. It is fitted into the engagement hole 68. Therefore, when the operating rod 95 moves downward, the transmission rod 102 moves downward with the base end portion 102a as a fulcrum, and the pin 102b provided on the transmission rod 102 moves downward to move the shutter member 100a downward. Therefore, the ball entrances 84a and 84b are opened. Further, when the front frame 70 is closed, the ball inlets 84a and 84b match the ball outlets 59a and 59b, and the shutter member 100a and the shutter member 66a are connected via the interlocking pin 100b. At the same time that 100a moves downward and the ball inlets 84a and 84b are opened, the shutter member 66a moves downward and the ball outlets 59a and 59b are opened. Therefore, the game ball paid out from the ball payout device 55 flows from the ball outlets 59a and 59b to the ball inlets 84a and 84b, and is paid out to the upper ball saucer 74 or the lower ball saucer 75.

On the other hand, when the locking device 78 is opened and the operating rod 95 and the shutter member 100a move upward, the ball inlets 84a and 84b are closed. At the same time, the interlocking pin 100b moves upward and the shutter member 66a moves upward, so that the ball outlets 59a and 59b are closed. Then, when the front frame 70 is opened, the interlocking pin 100b is disengaged from the engaging hole 68, but the shutter member 66a is maintained in the upward moving state due to the elasticity of the spring 67. Therefore, when the front frame 70 is opened, the game ball does not spill out from the ball outlets 59a and 59b and the ball inlets 84a and 84b.
Further, when the front frame 70 is closed, the engaging pieces 63a and 63b move the operating rod 95 downward via the engaging members 80a and 80b, and the shutter member 66a and the shutter member 100a move downward, so that the ball outlet 59a , 59b and ball entrances 84a, 84b are opened, and the game ball is paid out.

Next, the second embodiment of the ball game machine according to the present invention will be described with reference to FIGS. 23 to 34. In the second embodiment, the game board unit 1 is provided with a payout ball tank 110 for storing game balls. That is, in the first embodiment, the payout ball tank 58 is provided in the housing 40, but in the second embodiment, the payout ball tank 110 is provided at the upper edge of the case body 3 constituting the game board unit 1, and the payout ball tank 110 is provided. A game ball is supplied from the 110 to the ball payout device 55. The payout ball tank 110 is integrally formed with a ball supply gutter 111 for arranging the stored game balls in a row and causing them to flow out, and an opening / closing shutter 113 is provided at the downstream end 112 of the ball supply gutter 111. ing. By closing the opening / closing shutter 113 when the game board unit 1 is separated from the housing 40, the game ball in the payout ball tank 110 may spill out from the downstream end portion 112. It is something to prevent.

To explain the configuration of the opening / closing shutter 113 in more detail, as shown in FIGS. 25 to 27, the rectangular frame-shaped portion 113a of the opening / closing shutter 113 is larger than the outer diameter dimension of the downstream end portion 112 in the front-rear direction. A valve portion 113b is integrally formed on the inner surface of the front corner portion of the rectangular frame-shaped portion 113a so as to have an inner diameter, and a frame-shaped spring accommodating portion 113c is formed next to the rectangular frame-shaped portion 113a. A spring-stopping protrusion 113d is formed at one end of the spring accommodating portion 113c, and an elongated hole 113e is integrally formed on the outside of the spring accommodating portion 113c. Further, a hanging wall 111a and a boss 111b are formed on the lower surface of the ball supply gutter 111 of the payout ball tank 110, and a notch 112a through which the valve portion 113b can enter is formed in the front corner of the opening edge of the downstream end portion 112. It is formed. Then, the opening / closing shutter 113 is attached to the downstream end portion 112 so that the downstream end portion 112 is surrounded by the rectangular frame-shaped portion 113a, the hanging wall 111a is loosely inserted into the spring accommodating portion 113c, and the boss 111b is inserted. Is loosely inserted into the elongated hole 113e, and a headed screw 111c inserted into the elongated hole 113e from below is screwed to the boss 111b to support the opening / closing shutter 113 so as to be slidable in the front-rear direction. The coil spring 113f is accommodated in the spring accommodating portion 113c in a compressed state by engaging both ends of the spring retaining protrusion 111d and the spring retaining projection 113d formed on the inner surface of the hanging wall 111a. The opening / closing shutter 113 is always urged backward as shown in FIGS. 25 and 26. Due to this urging, the valve portion 113b faces the notch 112a, and the valve portion 113b projects into the ball passage of the downstream end portion 112, so that the game ball is prevented from falling from the downstream end portion 112. NS.
On the other hand, as shown in FIGS. 29 and 31, the ball payout device 55 fixedly installed in the housing 40 is formed with a ball entry port 55a capable of matching the downstream end portion 112 on the upper end surface. The piece 55b is fixed to the inner side surface on the right side of the housing 40 so as to be located on the upper rear side of the ball payout device 55 so that the piece 55b can come into contact with the opening / closing shutter 113.
Since the other configurations of the second embodiment are substantially the same as those of the first embodiment, detailed description thereof will be omitted by assigning the same reference numerals to the drawings of the second embodiment to the same parts or the corresponding parts as those of the first embodiment.

In the ball game machine shown in the second embodiment, with the game board unit 1 mounted in the housing 40, as shown in FIGS. 32 to 34, the opening / closing shutter 113 hits the piece 55b to open / close. By moving the shutter 113 forward against the elasticity of the coil spring 113f, the valve portion 113b is retracted from the notch 112a, so that the gaming ball in the payout ball tank 110 is ejected from the downstream end portion 112 to the ball payout device 55. It is supplied to the ball entry port 55a. Therefore, when the ball payout device 55 operates during the game, the game balls stored in the payout ball tank 110 are paid out to the ball tray on the front surface of the game machine.
On the other hand, when the front frame 70 and the game board unit 1 are opened as shown in FIG. 30, the opening / closing shutter 113 is separated from the piece 55b and pushed backward by the elasticity of the coil spring 113f, so that the valve portion 113b is notched. As it enters 112a, the downstream end 112 is closed. Therefore, for example, even if the game board unit 1 is opened as shown in FIG. 30 in an attempt to inspect the payout ball tank 110 due to ball clogging during the game, the game ball falls out from the downstream end 112. Instead, the hall employee can quickly clear the ball jam while the payout ball tank 110 is visible. As described above, in the ball game machine shown in the second embodiment, the payout ball tank 110 for storing the game balls is provided in the game board unit 1, so that the ball game machine can be opened by opening the game board unit 1. It becomes possible to easily check the status of the payout ball tank 110 from the front of the payout ball tank 110, and it is possible to quickly deal with a ball clogging or the like in the payout ball tank 110 during the game.

As described above, in the first and second embodiments, in the present invention, instead of the machine frame and the main body frame of the conventional ball game machine, the housing 40 is fixedly attached to the island stand of the game hall, and the housing is said. On the inner edge of the 40, non-replaceable parts such as a ball launching device 49, a ball payout device 55, a control board 56, and a power supply device 54, which do not need to be replaced at the same time when the game board 2 is replaced, are fixedly fixed. Therefore, the weight of these non-replaceable parts is borne by the housing 40, and it is no longer necessary to rotatably support a heavy object by a robust shaft support unlike a conventional machine frame or main body frame. At the same time as the cost is reduced, the space is widened, and a larger effect device 13 can be provided on the game board 2. As a result, the game can be made more interesting and powerful, and the entertainment of the ball game machine is enhanced.
Further, in the ball game machine according to the present invention, the locking device 78 may be provided with a function of holding the front frame 70 in the closed state with respect to the housing 40. Unlike a locking device, it does not require complicated key operations such as opening only the front frame or opening the main body frame at the same time depending on whether the key is rotated clockwise or counterclockwise. Therefore, the configuration of the locking device is simplified and the cost is reduced. Then, since only the front frame 70 is easily opened and closed by key operation, it is possible to deal with ball clogging in the game area on the front surface of the game board 2 during the game. In addition, the inspection and inspection of the main control board 23 and the ball payout control board 56 become easy. Further, by operating the clamp devices 46a and 46b with the front frame 70 open, the gaming board 2 can be easily replaced from the front of the gaming machine.

In the embodiment shown above, the ball launching operation handle 76 is provided on the front frame 70, but the game ball launching operation handle may be projected from the lower part of the front surface of the housing 40. Further, in the embodiment shown above, the locking device 78 and the cylinder lock 79 are provided on the front frame 70, but the locking device 78 and the cylinder lock 79 may be fixedly attached to one front side edge of the housing 40. .. Further, the ball striking device 72, the relay board case 73, the upper ball tray 74, the lower ball tray 75, etc. do not need to be replaced at the same time when the game board unit 1 is replaced. It may be formed.
By reducing the number of parts provided on the front frame 70 in this way, the front frame 70 can be made lighter, so that the weight burden on the multi-axis hinges 77a and 77b, which are the shaft support thereof, can be further reduced at the same time. The weight balance when the front frame 70 is opened can be improved.
Further, the housing 40 does not necessarily have to be formed in a box shape having a closed back surface as shown in the embodiment, but the strength can be increased by forming the housing 40 in a box shape as shown in the embodiment. In addition, since it can be manufactured robustly even if it is molded with a relatively thin iron plate, it is possible to secure a large space that can store a large production device, etc., and it is possible to maintain the strength that can be supported by a heavy front frame. ..
