  The shutter member 151 is a coil spring 157 in which guide struts 156 are inserted into the left and right bearing portions 155 from the rear, and a washer 159 is supported by the strut portions protruding forward, and a screw portion at the tip is supported on the support boss 158 side. The support boss 158 is screwed and fastened to be attached to the back side of the cover plate 51. When the shutter member 151 is attached in this manner, the shutter member 151 is supported so as to be slidable back and forth along the left and right guide columns 156, and is always urged rearward by the urging force of the coil spring 157, so that the blade portion 152 is moved. It is held in a closed position for closing the lower surface of the shutter opening 116.

  As described above, in the shutter mechanism 150, the shutter opening 116 uses the lower end corner portion of the protruding portion 106 to reduce the opening / closing stroke of the shutter member 151, and the front portion of the bearing portion 155 is shortened from the blade portion 152 to provide a coil spring. The housing dimensions of 157 are secured, and the support portion of the guide column 156 and the support portion of the coil spring 157 are gathered on the support boss 157, and the opening / closing stroke of the shutter member 151 and the expansion / contraction length of the coil spring 157 are secured. Is realized.

  On the other hand, a shutter receiving portion 160 that receives the shutter mechanism 150 is formed on the game assisting board 20 side. The shutter receiving portion 160 has a concave shape in which the speaker cover 31 located immediately above the collective opening 26 is notched in accordance with the position and shape of the protrusion 106 and the shutter mechanism 150 on the upper ball tray 5 side and opens forward. The projection 106 and the shutter mechanism 150 can be retractably accommodated in accordance with the closing and opening of the upper ball tray 5.

  The collective recovery port 26 is formed with a frame-like upper edge surface in accordance with the height position of the blade portion 152 in the shutter mechanism 150, and an engagement protrusion 163 that protrudes forward and extends to the left and right is formed at the center of the front surface. ing. The front end portion of the engagement protrusion 163 is formed in a smooth arc shape when viewed from the side, and the shutter mechanism 150 is smoothly received by the shutter receiving portion 160 when the upper ball tray 5 is swung in the closing direction. The engagement member 153 is engaged, and the engagement receiver 153 is pressed forward to slide the shutter member 151 forward against the urging force of the coil spring 157.

  In a state where the upper ball tray 5 is closed to the front frame 2, the passage cover 103 of the lower ball tray flow passage L10 and the case cover 31 of the game assisting board are disposed to face each other, while the rear portion of the shutter mechanism 150 and The protruding portion 106 is accommodated in the shutter receiving portion 160, and the blade portion 152 in the shutter mechanism is accommodated below the bottom wall 107 and disposed at an open position where the shutter opening 116 is opened. In the open position, the coil spring 157 is disposed without being in close contact with the compression shell, and a predetermined clearance is secured between the engagement receiving portion 153 and the back plate back 51 (partial enlarged view in FIG. 10). And the upper ball tray 5 can be securely closed and held while the entire shutter opening 116 is opened.

  In a state where the upper ball tray 5 is closed to the front frame 2, the passing-out bar 55 communicates with the upper outlet 25 on the game auxiliary board side at the upper part of the upper ball tray 5, and from the ball payout device 43 of the back set board 40. An upper ball tray discharge passage L5 connected to the upper discharge passage 45 to the upper outlet 25 to the outlet plate 55 to the ball tray portion 56 is formed, and the passage is made from the opening 111 formed in the outlet rod 55 on the front side of the front frame 2. A lower ball dish flow passage L10 that passes through the chamber 112, the inclined passage 113, the shutter opening 116, and the collect collection port 26 through the lower ball dish communication bucket 37 and the lower outlet 27 is formed.

  Further, in the shutter receiving portion 160, a spherical passage is formed which communicates in the vertical direction from the confluence 115 on the upper surface side of the protrusion 106 accommodated in the receiving portion to the collection recovery port 26 through the shutter opening 116 on the lower surface side, As a result, the foul balls dropped into the foul ball collection port 32 and the spilled balls dropped into the ball receiving port 35 are respectively joined from the foul ball collection passage 33 and the spilled ball collection passage 36 to the confluence 115 to the shutter opening 116 to the collection collection port. A collecting and collecting passage is formed to flow down to the lower ball tray 7 through the lower ball tray communication bucket 37 and the lower outlet 27.

  Now, the flow of game balls (action of each ball passage) in the pachinko machine PM configured as described above will be described below. As shown in FIG. 1, the pachinko machine PM is provided for a game with the upper ball tray 5 and the glass door 3 closed and locked, and the player stores the game ball in the ball tray portion 56 of the upper ball tray 5. The operation is started by rotating the operation lever of the firing handle 9. When the operation lever is turned, the game balls waiting to be aligned in the firing ball alignment passage 57 are sent one by one to the firing rail 22 by the ball feeding cassette disposed at the downstream end of the firing ball alignment passage 57. Then, it is launched by the hammer of the game ball launcher 21.

  Of the game balls launched by the hammer, the game balls that have returned along the outer rail 12 without reaching the game area PA fall into the foul ball collection port 32, pass through the foul ball collection passage 33, and protrude. From the junction 115 on the top surface of the unit, the shutter 116, the collection / recovery port 26, the lower ball tray connecting bucket 37 and the lower outlet 27 flow down to be collected in the lower ball tray 7.

  On the other hand, of the game balls hit by the hammer, the game ball that has reached the game area PA rolls and falls in the game area PA while being hit by a large number of game nails and windmills that are driven into the game area. In the process of dropping, it drops into the winning device 14 and is guided to the back side of the decorative plate 11, or falls without falling into the winning device 14 and is guided to the back side of the decorative plate 11 through the out port 18, Both are discharged through the game-completed ball discharge passage 48 of the back set board 40 to the game island collection device. The game balls won in the winning tool 14 are detected by a winning ball detector provided in each winning tool and a winning detection signal is output to the main control board, and the main control board outputs a payout signal corresponding to the type of the winning tool. This is output to the ball payout device 43 via the payout control board, and the ball payout device 43 pays out a predetermined number of game balls (for example, 5 balls, 10 balls, 13 balls, etc.) according to the payout signal.

  The game balls paid out from the ball payout device 43 are guided to the upper payout passage 45 by the partition wall 44 formed in the payout passage before the upper ball tray payout passage L5 is filled. It flows into the outlet 55 through the upper outlet 25. Here, on the entrance side of the doorway 55, a ball approaching side 55s for guiding the game ball that has flowed into the doorway 55 toward the center is provided. The game ball that flows down is guided to the ball approaching side 55s, passes through the side of the opening 111, and is guided to the ball tray 56.

  Therefore, until the paid-out game ball stops around the opening 111, specifically, the ball tray portion 56 is filled with the game ball and the game ball is stored in the outlet 55. Until the game ball is discharged, the game balls discharged from the ball dispensing device 43 flow down the upper dispensing passage 45 to the upper passage outlet 25 to the passage basket 55 and pass through the upper ball tray dispensing passage L 5 to reach the ball tray portion 56. There is hardly any game ball that is guided to the ball tray 56 and moves into the lower ball tray flow passage L10 from the opening 111 and flows down to the lower ball tray 7.

  As the game progresses, if there are more game balls to be paid out for winning than the game balls launched from the game ball launching device 21 to the game area PA, the number of stored balls in the ball tray portion 56 gradually increases. Along with this, the stored balls stored in the ball tray part 56 go back up the slope to cover the ball dish part, and further stack in a plurality of stages in front of the exit of the outlet bowl 55 where there is a step with the ball dish part 56. Go up and the whole ball tray is filled with game balls.

  When the ball tray is filled up to the front of the exit bowl 55 and the game balls are stored in the passage of the exit bowl 55, a part of the game balls stopped near the side edge of the opening 111 However, it is pressed in the direction of the opening 111 by the game ball newly flowing into the doorway and connected to the rear, and moves into the passage chamber 112 from the opening 111. The game ball transferred into the passage chamber 102 is guided by the flow-down guide piece 103 s disposed at the lower part of the passage chamber 102 to smoothly roll down the inclined passage portion 113, and from the shutter port 116 to the collective recovery ports 26 to 26. The lower ball tray 7 is guided to the lower ball tray 7 through the lower ball tray flow passage L10 that reaches the lower ball tray 7 via the lower ball tray communication bucket 37 to the lower outlet 27.

  Here, after the game ball starts to be stored inside the passage of the doorway 55, the game ball that moves into the passage chamber 112 from the opening 111 is located in the vicinity of the opening 111 (for convenience, A vector of a pressing force acting on the stationary ball from a game ball connected to the rear of the stationary ball, and a vector of a pressing force acting on the stationary ball from a game ball located in front of the stationary ball. The resultant force obtained by synthesizing is limited to the direction toward the opening 111. That is, the resultant force acting on the stationary ball is determined by the acting direction of the pressing force and the magnitude of the pressing force due to the contact angle positional relationship between the spherical surfaces of the stationary ball and the game balls located before and after the stationary ball. A stationary ball that is inward of the portion 111 moves into the passage chamber 112 from the opening 111.

  Accordingly, the game balls that are transferred from the opening 111 to the passage chamber 112 after the game balls start to be stored inside the passage of the doorway 55 have the above-mentioned conditions among the game balls stopped near the side edge of the opening 111. Part of the game ball is filled, the game ball is paid out from the ball payout device 43, the pressing force to the stationary ball fluctuates, and the ball stored in the ball tray portion 56 is consumed by the game ball being fired. Each time the stored balls in 55 gradually flow down and move, several balls are sequentially transferred from the opening 111 to the passage chamber 112 and flow down through the lower ball tray discharge passage L10 and are led to the lower ball tray 7.

  As a result, the player can recognize that the ball passage is gradually filling before the upper ball tray payout passage L5 is completely filled, and the game ball flows down to the lower ball tray 7 little by little. At this point, for example, a game facility staff is called using a game island call lamp LP or the like indicated by a two-dot chain line in FIG. 1, and a ball box BB is received to prepare for the ball removal work of the lower ball tray 7 It can be performed.

  When the game balls are paid out one after another in such a state that the game balls flow down to the lower ball tray 7 little by little in this way, the paid-out game balls are passed from the outlet 通 55 to the upper outlet 25 to the upper outlet passage. It is stored so as to go back to the upper ball tray payout passage L5 to 45, and is filled with game balls up to the upstream portion of the upper payout passage 45.

  When the game ball is further paid out from the ball payout device 43 in a state where the game ball is filled up to the upper end of the partition wall 44 that partitions the upper payout passage 45 and the lower payout passage 47, the partition wall 44 is dammed. The game balls that have passed over the partition wall 44 overflow to the lower payout passage 47 side, or bypass the overflow ball passage 46 and flow into the lower payout passage 47. It flows down the lower ball tray discharge passage L 7 connected to the lower ball tray 7 through the outlet 27 and is discharged to the lower ball tray 7.

  In this state, the number of pooled balls that are consumed and reduced gradually by the release of the game balls and the game balls that gradually flow from the opening 111 to the lower ball dish 7 through the lower ball dish flow passage L10 are about The game balls are supplied to the upper ball tray payout passage L5 side, and most of the newly released game balls are paid out to the lower ball tray 7 through the lower ball tray payout passage L7. That is, a small number of game balls are sequentially led out to the lower ball tray 7 until the upper ball tray payout passage L5 is filled after the ball tray portion 56 of the upper ball tray is filled, while the upper ball tray payout passage L5. After the game is filled, a large number of game balls are paid out to the lower ball tray 7, and the player can thereby accurately recognize that the upper ball tray payout passage L5 is full.

  Therefore, the player arranges the ball box BB prepared at the notice notification stage below the ball outlet of the lower ball tray 7 and observes the state of paying out and storing the lower ball tray 7 and the lower ball removing mechanism. The ball removal operation can be performed by operating the 8 ball removal lever.

  If the stored balls in the lower ball tray 7 increase and fill up without performing the ball removal operation, the paid-out game balls fill the lower ball tray communication bucket 37 from the lower outlet 27, and further the lower ball tray The lower payout passage 47 is filled so as to go back through the payout passage L7. When the storage ball is filled up to the passage position of the full detector 49 provided in the lower payout passage 47 and a full detection signal is output from the full detector 49 to the main control board, the main control board detects the detection signal. Based on this, the operations of the ball payout device 43 and the game ball launching device 21 are restricted, and the payout operation and the firing operation are stopped.

  Here, in the path mechanism of this configuration, in addition to the lower ball tray discharge passage L7, a lower ball tray discharge passage L10 is provided separately, and even after the upper ball tray discharge passage L5 is filled with the stored balls, the lower ball tray A game ball that flows into the lower ball tray connecting bucket 37 from behind through the payout passage L7 and a game ball that flows into the lower ball tray connecting bucket 37 from the front through the lower ball tray flowing down passage L10 coexist. For this reason, the number of game balls that can be stored before the operation restriction based on the detection signal of the full detector 49 is applied is in addition to the numbers that can be stored in the upper and lower ball trays 5 and 7 and the upper and lower ball tray discharge passages L5 and L7. Thus, it is possible to increase the quantity stored in the lower ball tray flow passage L10, thereby extending the time until the operation restriction is applied, so that a large number of game balls are paid out to the lower ball tray 7. The ball removal work can be done with a margin without panic.

  By the way, in the pachinko machine, a ball clogging may occur in the ball feeding cassette attached to the back side of the upper ball tray 5, or a plurality of game balls may be detained on the launch rail 22 so that the game balls cannot be fired. During the game, it is necessary to open the upper ball tray 5 to solve the problem. The shutter mechanism 150 is provided so that even when game balls remain in the ball path of the upper ball tray 5 when the upper ball tray 5 is opened, these remaining balls do not fall out.

  When the upper ball tray 5 is unlocked from the state where the upper ball tray 5 is closed and locked and pulled forward, the upper ball tray 5 swings around the hinge pin of the hinge mechanism 4 provided on the left side of the front surface as a swing shaft. As shown in FIGS. 11 and 12, the protruding portion 106 and the shutter mechanism 150 in the lower sphere dish lowering passage L10 move away from the state accommodated in the shutter accommodating portion 160 and move to the front of the shutter accommodating portion 160, so 55 changes from being in communication with the upper outlet 25 to being separated from the upper outlet 25 in front of the upper outlet 25.

  At this time, in the shutter mechanism 150, the protrusion 106 moves forward, and the engagement protrusion 163 on the game auxiliary board side is displaced relatively rearward, so that it is in contact with and pressed against the engagement protrusion 163. The pressing force applied to the engagement receiving portion 153 is released, and the shutter member 151 slides backward by the elastic force of the compressed coil spring 157, and the blade portion 152 closes the lower surface of the shutter port 116.

  For this reason, when the upper ball tray 5 is opened, the game balls already stored in the lower ball tray flow passage L10 or when the upper ball tray 5 is opened, it flows into the lower ball tray flow passage L10 from the opening 111. The game ball is held by the blade portion 152 and held in the lower ball dish flow passage L10, and ball spillage does not occur.

  Further, since the lower ball tray flow passage L10 and the ball discharge flow passage 58 are merged and the shutter mechanism 150 is provided on the downstream side of the merge portion, for example, when the upper ball tray 5 is opened or after the upper ball is accidentally opened. Even when the ball removal operation lever of the removal mechanism 6 is operated in the opening direction, the game ball that has flowed down the ball removal flow path 58 and joined through the ball removal port 59 is blocked by the blade portion 152 and removed. It is held in the flow-down passage 58 and does not cause spilling of the ball as described above.

  Furthermore, in the shutter mechanism 150, the shutter member 151 slides back and forth in conjunction with the closing / opening of the upper ball tray 5 to open / close the shutter opening 116. There is no need to perform an operation, and a route mechanism with good workability can be provided.

  On the other hand, a ball receiving opening 35 is formed below the gap between the outlet bowl 55 and the upper outlet 25 generated when the upper ball tray 5 is opened, and the case cover 31 projects forward. A spilled ball collecting passage 36 is formed below the spilled ball that has fallen into the ball receiving port 35.

  For this reason, even if game balls are stored in the upper ball tray payout passage L5 before the upper ball tray 5 is opened, the spilled balls overflowing forward from the upper outlet 25 when the upper ball tray 5 is opened. Then, the spilled ball overflowing rearward from the outlet 55 drops into the ball receiving port 35 which is located on the lower side and opens upward, flows down the spilled ball collection passage 36, and the protruding portion 106 is detached. The shutter accommodating portion 160 falls and is collected in the lower ball tray 7 through the lower collection tray 26 through the lower ball tray communication bucket 37 to the lower outlet 26. Therefore, even when the game balls are stored in the upper ball tray payout passage L5 when the upper ball tray 5 is opened, the overflowing game balls pass through the spilled ball collection passage 36 to the lower ball tray 7. It will not be collected and scattered game balls.

  Therefore, by providing the path mechanism as described above, it is possible to prepare a ball box with sufficient time and spirit until both the upper and lower ball tray dispensing passages are full, and the upper ball tray is opened. In this case, a pachinko machine can be provided in which even when game balls remain in each ball passage, these game balls are not scattered.

  Next, the lower ball dish flow passage L20 in the second configuration form will be described. Here, FIG. 13 is a front view showing each ball passage on the game assisting board side with the upper ball tray 5 opened, and FIG. 14 is a front view showing each ball passage on the upper ball tray side with the upper ball tray closed. 15 is a rear view of the upper ball tray 5 mainly showing the lower ball tray flow passage L20, FIG. 16 is an exploded perspective view showing the configuration of the opening and shutter mechanism of the lower ball tray flow passage L20, and FIG. 18 is a cross-sectional plan view of the periphery of the shutter mechanism as viewed in the direction of the arrow XVII-XVII, FIG. 18 is a cross-sectional plan view of the pachinko machine PM mainly showing the upper ball tray discharge passage L5 and the lower ball tray flow-down passage L20, and FIG. FIG. 20 is a side sectional view of the pachinko machine PM for explaining the flow of the game ball at the time, FIG. 20 is a plan sectional view showing the positional relationship of each ball passage and the state of the shutter mechanism when the upper ball tray 5 is opened, FIG. Is for explaining the flow of the game ball when the upper ball tray 5 is opened It is a side sectional view of a pachinko machine PM.

  In the route mechanism of this configuration, the lower ball tray flow passage L20 that communicates between the outlet bowl 55 and the lower ball tray 7 with the upper ball tray 5 closed to the front frame 2 is provided on the front surface of the game auxiliary board 20. The spilled ball collecting passage 36 provided on the side is configured to be used in combination, the configuration of the game auxiliary board 20 excluding the opening width of the ball receiving port 35, and the lower ball dish flow passage L10 formed on the back surface of the counter plate 51. The main configuration of the upper ball tray 5 except for the same is the same as that of the pachinko machine PM described with reference to FIGS. Therefore, the same parts are denoted by the same reference numerals, and a duplicate description is omitted. Hereinafter, the lower ball dish flow path L20 will be described in detail.

  The lower ball tray flow passage L20 has a ball receiving port 35 located below the exit rod 55 in a state where the upper ball plate 5 is closed to the front frame 2, and the game ball dropped into the ball receiving port 35 is placed in the lower ball plate. 7 is used in combination with a spilled ball collection passage 36 that is caused to flow down to 7. An opening 211 is formed on the entrance side (the rear end side communicating with the upper exit 25) of the outlet rod 55 so that a part of the bottom surface on the left side in front view is cut out and communicates vertically. A branch flow path that branches from the upper ball tray payout passage L5 through the opening 211 is formed.

  Here, in the upper payout passage 45, as shown in FIG. 18, a first tilt guide side 45s for guiding the game ball paid out from the ball payout device 43 to the lower right, and the first tilt guide side The second inclined guiding side 45t that guides the game ball guided by 45s forward is provided, and the gaming ball paid out from the ball payout device is guided to the inclined guiding sides 45s and 45t and paid upward. The passage 45 flows down while being turned so as to turn clockwise in plan view. For this reason, in the vicinity of the entrance of the upper exit 25 to the exit pole 55, the game ball flows down the area on the right side of the ball passage, and the game ball is stored up to the inside of the upper exit 25 and is applied to the game ball stopped in the passage. There is a characteristic that almost no game ball passes through the region on the left side until it is guided leftward.

  Based on the above characteristics, the opening 211 is formed by partially cutting away the passage surface on the left side of the entrance of the exit rod 55 where game balls hardly flow down, and makes the exit rod 55 oblique. A partition wall 55t that protrudes upward and extends forward and backward is formed on the side edge near the center of the opening 211 so that the game ball that flows down does not directly transfer into the opening 211.

  Below the opening 211, a cover portion of the speaker cover 31 projects forward to form a ball receiving opening 35 that opens upward, and a spilled ball collection passage that allows the game balls that have fallen into the ball receiving opening 35 to flow downward. 36 is formed. As described above, the spilled ball collection passage 36 merges with the foul ball collection passage 33 at the substantially right and left central portions of the game assisting board 20 and vertically penetrates the shutter receiving portion 160 that receives the shutter mechanism 150 and the front frame 2. It is connected to the lower ball tray communication bucket 37 via the collective recovery port 26. Thereby, in a state where the upper ball tray 5 is closed to the front frame 2, the ball receiving port 35 to the spilled ball collecting passage 36 to the shutter receiving portion 160 to the collective collecting port 26 to the lower ball tray connecting bucket 37 to the lower passage from the opening 211. A lower ball dish flow passage L20 connected to the lower ball dish 7 through the outlet 27 is formed.

  On the other hand, a protrusion 206 is formed on the back side of the counter plate 51 in the upper ball tray 5 so as to surround the ball outlet 59 and protrude rearward. The shutter 206 is similar to the shutter mechanism described above. 150 is provided.

  The projecting portion 206 is formed in a box shape that surrounds the periphery of the ball outlet 59 by the left and right passage walls 201 and 202, the upper surface wall 204, the bottom wall 205, and the rear wall 207. At the rear of the projecting portion 206, a confluence 215 is formed on the upper surface side, and a shutter port 216 is formed on the lower surface side, and a ball passage extending in the vertical direction is formed so as to be connected to the ball outlet flow passage 58. The projecting portion 206 is configured such that the rear portion of the projecting portion 206 is accommodated in the shutter receiving portion 160 in the closed state of the upper ball tray 5, and the junction port 215 and the shutter port 216 are located in the shutter receiving portion 160. Thus, a part of the lower ball dish flow path L20 is configured, and the ball discharge flow path 58 and the lower ball dish flow path L20 merge in the shutter receiving portion 160.

  The shutter mechanism 150 has a shutter member 151 that opens and closes a shutter port 216, left and right guide columns 156 that support the shutter member 151 so as to be slidable in the front-rear direction, and a shutter member 151 that is supported by the left and right guide columns 156. A coil spring 157 urging in the closing direction), a support boss 158 that is formed on the outside of the left and right passage walls 201 and 202 and protrudes rearward to support the guide strut 156 and the coil spring 157, and the collective recovery port 26 on the side of the game auxiliary board It is comprised from the engagement protrusion 163 etc. which were protrudingly molded by the front-end part. The shutter mechanism 150 is configured in the same manner as the described shutter mechanism, as is apparent from a comparison of the exploded perspective view shown in FIG. 7 and the exploded perspective view shown in FIG. The same numbers are given to the constituent parts, and the duplicated explanation is omitted.

  The confluence 215 of the projecting portion 206 in this configuration form has a configuration in which the upper portion of the rear wall 207 is formed shorter than the left and right passage walls and the upper end corner portion is cut away. Even when the game balls are filled up above the junction 215, the upper ball tray 5 can be opened without the stored game balls biting between the junction 215 and the shutter receiving portion 160. ing. The shutter port 216 is formed by cutting out the lower part of the rear wall 207 and using the lower corner portion, and gathers the game balls flowing down from the lower ball dish flow path L20 and the ball discharge flow path 58 obliquely rearward. The shutter port 216 can be opened and closed with a relatively small slide stroke in the front-rear direction while flowing smoothly toward the recovery port 26.

  On the other hand, a shutter receiving portion 160 that receives the shutter mechanism 150 is formed on the game assisting board 20 side. Similarly to the shutter receiving portion described above, the shutter receiving portion 160 is also formed in accordance with the arrangement position and the protruding shape of the protruding portion 206 and the shutter mechanism 150 on the upper ball tray 5 side. The protrusion 206 and the shutter mechanism 150 can be retractably accommodated according to the opening. Further, an engaging protrusion 163 that protrudes forward and extends to the left and right is formed at the center of the front surface of the collective collection port 26, and is engaged with and disengaged from the engagement receiving portion 153 of the shutter mechanism 150 according to closing and opening of the upper ball tray 5. The shutter member 151 is slid to open and close the shutter port 216.

  In a state where the upper ball tray 5 is closed to the front frame 2, the rear portion of the shutter mechanism 150 and the protruding portion 206 are accommodated in the shutter receiving portion 160, and the blade portion 152 is accommodated below the bottom wall 205 and It is arrange | positioned in the open position which opens 216. In the open position, the coil spring 157 is disposed without being in close contact with the compression shell, and a predetermined clearance is secured between the engagement receiving portion 153 and the back plate back 51 (see a partially enlarged view in FIG. 19). ), The upper ball tray 5 can be reliably closed and held while the entire shutter port 216 is opened.

  In a state where the upper ball tray 5 is closed to the front frame 2, the passing-out bar 55 communicates with the upper outlet 25 on the game auxiliary board side at the upper part of the upper ball tray 5, and from the ball payout device 43 of the back set board 40. An upper ball tray discharge passage L5 connected to the upper discharge passage 45 to the upper outlet 25 to the outlet bowl 55 to the ball tray portion 56 is formed.

  Further, on the front side of the front frame 2, the ball receiving port 35 through the spilled ball collecting passage 36 through the collecting port 215 and the shutter port 216 are passed through the opening 211 formed in the outlet bowl 55, and the collecting and collecting port 26 communicates with the lower ball tray. A lower ball dish flow path L20 connected to the lower ball dish 7 via the bucket 37 to the lower communication outlet 27 is formed, and a ball discharge flow path 58 extended rearward by the protrusion 206 is formed in the shutter receiving part 160. There is a ball draining flow passage that joins with the lower ball tray flow passage L20 and is connected to the lower ball tray 7 through the ball discharge flow passage 58, the shutter port 216, the collection recovery port 26, the lower ball tray communication bucket 37, and the lower communication outlet 27. It is formed.

  In the path mechanism configured as described above, of the game balls launched by the hammer, the game balls that have returned without reaching the game area PA fall into the foul ball collection port 32 and fall into the foul ball collection passage 33. , And then flows down from the junction port 215 through the shutter port 216 to the collection / recovery port 26 to the lower ball tray connecting bucket 37 and the lower outlet 27 and is collected in the lower ball tray 7.

  On the other hand, of the game balls hit by the hammer, the game ball that has reached the game area PA rolls and falls on the game area PA while being hit by a game nail or windmill in the game area. And is guided to the back side of the decorative board 11, or dropped without falling into the prize-winning device 14 and guided to the back side of the decorative board 11 through the out port 18, It is discharged to the game island collection device through the game-completed ball discharge passage 48. The game ball won in the prize tool 14 is detected by the prize ball detector and a prize detection signal is output to the main control board, and the main control board sends a payout signal corresponding to the type of the prize tool through the payout control board. The ball payout device 43 pays out a predetermined number of game balls according to the payout signal.

  The game balls paid out from the ball payout device 43 are guided to the upper payout passage 45 by the partition wall 44 formed in the payout passage before the upper ball tray payout passage L5 is filled. It flows into the outlet 55 through the upper outlet 25. Here, as described above, the upper payout passage 45 is provided with the first and second inclined guide sides 45s and 45t, and the game balls flowing in from the upper payout passage 45 are arranged on the inclined guide sides 45s and 45t. Due to the action, the gas flows into the outlet rod 55 through a path on the right side of the opening 211, and a partition wall 55 t is erected on the side edge of the opening 211.

  Therefore, until the game ball is stored and stopped inside the upper passage 25, the game ball that has flowed into the passage 55 flows down the right region without contacting the partition wall 55t, or It is guided by the partition wall 55t to flow down the central portion, and all flow into the ball tray portion 56 without moving into the opening 211. That is, until the ball tray portion 56 is filled with the game balls and the game balls are stored retroactively to the inside of the outlet bowl 55 to the upper outlet 25, the game balls paid out from the ball payout device 43 are stored. The upper ball discharge passage 45 to the upper outlet 25 to the discharge rod 55 flow down to the ball tray portion 56 and is guided to the ball tray portion 56 through the upper ball tray discharge passage L5. A game ball that moves into the passage L20 and flows down to the lower ball tray 7 hardly occurs.

  On the other hand, if there are more game balls to be paid out for winning than the game balls launched from the game ball launcher 21 to the game area PA, the number of stored balls in the ball tray portion 56 gradually increases. Accordingly, the stored balls stored in the ball tray part 56 go back up the slope to cover the ball dish part, and further piled up in multiple stages in front of the exit of the outlet bowl 55 having a step difference from the ball dish part 56. The entire dish is filled with game balls.

  When the game ball is filled up to the entrance of the doorway 55 and the game ball stops inside the passage of the upper exit 25, the game ball that has flowed into the upper passage 25 gradually starts from the side of the right passage wall. The partition wall 55t is also stopped and the game ball newly flowing in from the upper payout passage 45 is bounced by the game ball stopped in this way and guided leftward, or in the vicinity of the partition wall 55t. The game ball that has been stopped is pressed by the game ball that has been stopped rearward and pushed leftward, and moves into the ball receiving port 35 from the opening 211. The game balls that have moved into the ball receiving port 35 roll down smoothly through the spilled ball collecting passage 36 and fall into the junction port 215, and from the shutter port 216 to the collecting / collecting port 26 to the lower ball tray connecting bucket 37 to the lower outlet 27. Is passed to the lower ball tray 7 through the lower ball tray flow passage L20 that reaches the lower ball tray 7.

  Here, after the game ball starts to be stored in the passage of the upper exit 25, the game ball transferred to the ball receiving port 35 from the opening 211 is a game ball (stopped ball) already stopped at the upper exit 25. There is a game ball that is touched and played in the direction of the opening 211, and a game ball that is pushed backward by the stored game ball and pushed out in the direction of the opening 211. Of these, the former is a game ball whose rolling direction is played toward the opening 211 on the left side when viewed from the front, in other words, a stop ball. The reflection direction determined according to the contact angle position between the spherical surfaces of the ball and the newly flowing game ball is limited to the game ball directed to the left.

  For the latter, a vector of pressing force acting on the stationary ball from the game ball connected to the rear of the stationary ball and a vector of pressing force acting on the stationary ball from the gaming ball located in front of the stationary ball. The resultant resultant force is limited to the direction toward the left (front of the opening of the opening 211). In other words, the resultant force acting on the stationary ball is determined by the acting direction of the pressing force and the magnitude of the pressing force due to the contact angle positional relationship between the spherical surfaces of the stationary ball and the game balls located before and after the stationary ball. Only the stationary ball in the direction is pushed out and transferred into the ball receiving port 35 from the opening 211.

  Accordingly, the game balls that are transferred from the opening 211 to the ball receiving port 35 after the game balls start to be stored inside the passage of the doorway 55 are game balls that satisfy the above conditions among the game balls that are stopped at the upper exit 25. Then, the game balls are paid out from the ball dispensing device 43 and played by the stationary balls, or the stored balls in the ball tray portion 56 are consumed by the launch of the game balls, and the stored balls in the upper outlet 25 gradually flow down and stop. Each time the pressing force on the sphere fluctuates, a small number is transferred from the opening 211 to the sphere receiving port 35, flows down the lower sphere tray discharge passage L <b> 20, and is led to the lower sphere tray 7.

  As a result, the player can recognize that the ball passage is gradually filling before the upper ball tray payout passage L5 is completely filled, and the game ball flows down to the lower ball tray 7 little by little. At this point, for example, a game facility staff is called using a game island call lamp LP or the like indicated by a two-dot chain line in FIG. 1, and a ball box BB is received to prepare for the ball removal work of the lower ball tray 7 It can be performed.

  When the game balls are paid out one after another in such a state that the game balls flow down to the lower ball tray 7 little by little in this way, the game balls that have been paid out are transferred from the upper outlet 25 to the upper payout passage 45. It is stored so as to go back through the dish payout passage L5 and is filled with game balls up to the upstream portion of the upper payout passage 45.

  When the game ball is further paid out from the ball payout device 43 in a state where the game ball is filled up to the upper end of the partition wall 44 that partitions the upper payout passage 45 and the lower payout passage 47, the partition wall 44 is dammed. The game balls that have passed over the partition wall 44 overflow to the lower payout passage 47 side, or bypass the overflow ball passage 46 and flow into the lower payout passage 47. It flows down the lower ball tray discharge passage L 7 connected to the lower ball tray 7 through the outlet 27 and is discharged to the lower ball tray 7.

  In this state, the amount of the game is a combination of the pooled balls that are consumed and gradually decreased due to the launch of the game balls, and the game balls that gradually flow from the opening 211 to the lower ball tray 7 through the lower ball dish flow passage L20. The balls are replenished to the upper ball tray payout passage L5 side, and most of the newly released game balls are paid out to the lower ball tray 7 through the lower ball tray payout passage L7. That is, a small number of game balls are sequentially led out to the lower ball tray 7 until the upper ball tray payout passage L5 is filled after the ball tray portion 56 of the upper ball tray is filled, while the upper ball tray payout passage L5. After the game is filled, a large number of game balls are paid out to the lower ball tray 7, and the player can thereby accurately recognize that the upper ball tray payout passage L5 is full.

  Therefore, the player arranges the ball box BB prepared at the notice notification stage below the ball outlet of the lower ball tray 7 and observes the state of paying out and storing the lower ball tray 7 and the lower ball removing mechanism. The ball removal operation can be performed by operating the 8 ball removal lever.

  If the stored balls in the lower ball tray 7 increase and fill up without performing the ball removal operation, the paid-out game balls fill the lower ball tray communication bucket 37 from the lower outlet 27, and further the lower ball tray The lower payout passage 47 is filled so as to go back through the payout passage L7. When the storage ball is filled up to the passage position of the full detector 49 provided in the lower payout passage 47 and a full detection signal is output from the full detector 49 to the main control board, the main control board detects the detection signal. Based on this, the operations of the ball payout device 43 and the game ball launching device 21 are restricted, and the payout operation and the firing operation are stopped.

  Here, in the route mechanism of this configuration, in addition to the lower ball tray discharge passage L7, a lower ball tray flow passage L20 is provided separately, and even after the upper ball tray discharge passage L5 is filled with stored balls, the lower ball tray A game ball that flows into the lower ball tray connecting bucket 37 from behind through the payout passage L7 and a game ball that flows into the lower ball tray connecting bucket 37 from the front through the lower ball tray flowing down passage L20 coexist. For this reason, the number of game balls that can be stored before the operation restriction based on the detection signal of the full detector 49 is applied is in addition to the numbers that can be stored in the upper and lower ball trays 5 and 7 and the upper and lower ball tray discharge passages L5 and L7. Thus, it is possible to increase the quantity stored in the lower ball tray flow passage L20, thereby extending the time until the operation restriction is applied, and a large number of game balls are paid out to the lower ball tray 7. The ball removal work can be done with a margin without panic.

  In addition, in the pachinko machine, a ball clogging may occur in the ball feeding cassette attached to the back side of the upper ball tray 5, or a plurality of game balls may be detained on the launch rail 22 so that the game balls cannot be fired. During the game, it is necessary to open the upper ball tray 5 to solve the problem. The shutter mechanism 150 is provided so that even when game balls remain in the ball draining flow path 58 of the upper ball tray 5 when the upper ball tray 5 is opened, these remaining balls do not fall out.

  When the upper ball tray 5 is unlocked from the state where the upper ball tray 5 is closed and locked and pulled forward, the upper ball tray 5 swings around the hinge pin of the hinge mechanism 4 provided on the left side of the front surface as a swing shaft. As shown in FIGS. 20 and 21, the protruding portion 206 and the shutter mechanism 150 in the lower sphere dish lowering passage L <b> 20 are moved away from the state accommodated in the shutter accommodating portion 160, and moved to the front of the shutter accommodating portion 160. 55 changes from being in communication with the upper outlet 25 to being separated from the upper outlet 25 in front of the upper outlet 25. Here, since the rear wall 207 of the protruding portion 206 is formed with a short upper portion and the junction 215 is provided at the upper corner of the projection 206, the lower ball dish flow passage L20 is located above the junction 215. Even when the game balls are filled with the ball, the stored game balls can fall into the collective recovery port 26 without being caught between the junction 215 and the shutter receiving portion 160 to open the upper ball tray 5. it can.

  In the shutter mechanism 150, the engagement that has been pressed against the engagement protrusion 163 as the protrusion 206 moves forward and the engagement protrusion 163 on the game auxiliary board side is displaced relatively rearward. The pressing force to the receiving portion 153 is released, and the shutter member 151 slides backward due to the elastic force of the compressed coil spring 157, and the blade portion 152 closes the lower surface of the shutter port 216.

  Therefore, for example, even when the upper ball tray 5 is opened or after the upper ball tray 5 is opened, the ball removal operation path of the upper ball removal mechanism 6 is accidentally operated in the opening direction. The game ball that has flowed down is blocked by the blade portion 152 and held in the ball draining flow passage 58, and ball spillage does not occur. Further, in the shutter mechanism 150, the shutter member 151 slides back and forth in conjunction with the closing / opening of the upper ball tray 5, and the shutter opening 216 is opened / closed. There is no need to perform an operation, and a route mechanism with good workability can be provided.

  On the other hand, a ball receiving opening 35 is formed below the gap between the outlet bowl 55 and the upper outlet 25 generated when the upper ball tray 5 is opened, and the case cover 31 projects forward. A spilled ball collecting passage 36 is formed below the spilled ball that has fallen into the ball receiving port 35.

  For this reason, even when the upper ball tray 5 is stored in the upper ball tray discharge passage L5 before the upper ball tray 5 is opened, the spilled balls overflowing forward from the upper outlet 25 when the upper ball tray 5 is opened and The spilled ball overflowing rearward from the tap 55 drops into the ball receiving port 35 located below and opening upward, and flows down the spilled ball collecting passage 36, and the shutter housing part from which the protruding part 206 is detached. 160 is dropped and collected from the collective collection port 26 to the lower ball tray 7 through the lower ball tray connecting bucket 37 to the lower outlet 26. Therefore, even when the game balls are stored in the upper ball tray payout passage L5 when the upper ball tray 5 is opened, the overflowing game balls pass through the spilled ball collection passage 36 to the lower ball tray 7. It will not be collected and scattered game balls.

  Therefore, by providing the path mechanism as described above, it is possible to prepare a ball box with sufficient time and spirit until both the upper and lower ball tray dispensing passages are full, and the upper ball tray is opened. In this case, a pachinko machine can be provided in which even when game balls remain in each ball passage, these game balls are not scattered.

  In this configuration, an example in which the partition wall 55t is integrally formed on the side edge of the opening 211 of the outlet rod 55 is shown. However, for example, a clip-shaped partition member 255 as shown in FIG. The partition wall 255 t that is formed separately from the upper wall 55 and protrudes upward may be configured to be locked and fixed to the entrance side of the outlet rod 55 according to the side edge of the opening 211.

  In each of the configuration modes described above, the configuration example in which the shutter member 152 slides back and forth to open and close the shutter port is shown. However, the opening and closing mode of the shutter mechanism 150 is not limited to the front and back slide, for example, slides to the left and right. Thus, the shutter opening / closing may be performed or the shutter opening / closing may be performed by swinging up and down. In addition, bells are arranged on either one of the lower ball tray flow-down passages L10, L20 or the lower ball tray discharge passage L7, or a tone is generated on each of the lower ball tray flow-down passage and the lower ball tray discharge passage. Different bells may be arranged so that when a game ball passes through each ball passage, a sound effect is generated by contacting the bell, thereby further clarifying the notice function. .
