[Prior art]
Conventionally, a start winning ball detector detects that a hit ball has won a start winning opening, derives a display result of the variable display device based on the detection signal, and the display result becomes a predetermined specific display result. There are many ball game machines on the market that are in a big hit game state and give a chance to win a large number of winning balls by repeatedly opening a variable winning ball device, for example. In such a ball game machine, whether or not the display result of the variable display device displays a specific display result is a big hit that is extracted at the time of starting winning of the hit ball (at the time of detection of the starting winning ball detector) It was determined by a random number for determination. The random number for determining the big hit changes every moment at a predetermined speed (for example, 2 msec) from when the power is turned on.
[0003]
[Problems to be solved by the invention]
By the way, in recent years, a counter which changes in synchronization with the random number for determining the big hit is incorporated in the middle of the wiring connecting the start winning ball detector and the game control circuit board, and the detection signal from the start winning ball detector Is stored, and when the value of the counter reaches a predetermined value (the same value as the big number of random numbers for determining the big hit), an illegal circuit board that sends a detection signal to the game control circuit board is connected. I found out that the cheating is being done. In addition, for the purpose of performing the same fraud as the above-mentioned fraudulent circuit board, for example, a fraudulent circuit board that is sent to a game control circuit board as if there was a start signal when a radio signal of a predetermined frequency is used is also used. I found out. Then, such illegal circuit boards are hidden in a bundle of wirings so that an illegal act is not easily detected. The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a ball game machine in which an unauthorized circuit board cannot be connected between the start winning ball detecting means and the game control circuit board. .

FIG. 3 is a perspective view showing an attachment state of the substrate storage box 80, and FIG. 4 is a cross-sectional view of the substrate storage box 80 attached to the mechanism plate 50.
[0020]
As shown in FIG. 3, the board storage box 80 includes an assembly of a lid body 82 and an attachment base 81 that accommodates the game control circuit board 87 therein. It is configured to be attached to the mechanism plate 50. The mounting base 81 is formed in a box shape whose upper surface is opened by a conductive synthetic resin, and an engaging rail 83 that engages with an engaging rail 111 formed on the mounting base 110 is formed on the back side of the bottom surface. Yes. Further, an opening (not shown) through which the inside can be seen is formed on the bottom surface of the mounting base 81, and a transparent bottom plate 84 is provided in a laminated manner inside the bottom surface so as to close the opening. In the case of the illustration, a transparent bottom plate 84 is provided in a laminated form so as to close an elongated opening (a plurality of openings along the vertical direction in FIG. 4 are provided). After passing through the mounting bosses 85 protruding from the inner four corners of the mounting base 81, the interval holding cylinder 86 is loosely fitted to the mounting boss 85, and then the game control circuit board 87 is brought into contact with the mounting boss 85. By fixing with a screw, it is attached in a state of being in contact with the bottom surface of the attachment base 81.
[0021]
As is well known, the game control circuit board 87 attached to the mounting boss 85 is mounted with electronic parts such as a CPU, ROM, RAM, etc. and a connecting part such as a connector 104 constituting a microcomputer on one side thereof. . In the case of the illustrated embodiment, an upper region in the width direction is configured as a connector mounting region, and a lower portion of the connector mounting region is formed as an electronic component mounting region. When the lid 82 is assembled to the mounting base 81, the connector mounting area 103 is the connector mounting area exposed to the outside.
[0022]
Incidentally, the game control circuit board 87 in the present embodiment is provided with a ball passage 90 through which a hit ball can pass vertically. Specifically, the ball passage 90 is composed of a plate rectangular ball passage configuration first member 88 and a ball passage configuration second member 89 having a U-shaped cross section whose one side is closed by the ball passage configuration first member 88. The pachinko ball is configured as a path through which the inside falls from top to bottom. The ball path configuration first member 88 is screwed in a state of being slightly lifted from the game control circuit board 87 by mounting pieces 96 formed of transparent synthetic resin and projecting above and below the ball path configuration second member 88. The member 89 is also made of a transparent synthetic resin and is screwed in a state where it is slightly lifted from the game control circuit board 87 by mounting pieces 97 protruding upward and downward. Further, the ball passage 90 is formed over substantially the entire length in the width direction of the game control circuit board 87. In the middle of the ball passage 90 configured as described above, a start winning ball detector 93 as a start winning ball detection means is provided in the recesses 91 and 92 of the ball passage configuration first and second members 88 and 89. It is locked and attached to. In the illustrated embodiment, a proximity switch is used as the start winning ball detector 93, but a micro switch, a photo switch, or the like may be used. In particular, in the case of a photo switch, since it can be directly mounted on the game control circuit board 87, it becomes more difficult to connect an unauthorized circuit board in the middle thereof. The wiring 94 extending from the start winning ball detector 93 is connected to the game control circuit board 87 by a connector 95.
[0023]
With the game control circuit board 87 configured as described above attached to the attachment base 81, the lid body 82 is assembled so as to cover the electronic component mounting area excluding the connector connection area 103. The lid body 82 is formed in a flat plate shape with a transparent synthetic resin through which the inside can be seen through, and an electronic component mounting area and a connector mounting area are partitioned by a bent side portion 82a bent along the upper side. A cutout opening 98 is formed in the bent side portion 82a at a position corresponding to the ball passage 90 so that the lid 82 can be attached to the attachment base 81 smoothly.
[0024]
By the way, the attachment structure of the lid 82 to the attachment base 81 includes an engagement piece 101 which is bent at right angles with an appropriate interval on both sides and the lower side of the lid 82 and the engagement piece 101. It is attached by guide ribs 100 protruding at appropriate intervals along the outer periphery of the inner surface of the lid 82 so as to sandwich the upper side portion of the attachment base 81. In some cases, it is difficult to remove the lid 82 thereafter by applying an adhesive or the like to the outer surface of the guide rib 100 and holding the upper side of the mounting base 81 between the guide rib 100 and the locking piece 101. It may be made to become. Whether the adhesive is used or not, when the lid 82 is attached to the attachment base 81, a seal seal 102 is pasted between the lid 82 and the attachment base 81. It is desirable to do. As the seal seal 102, a hologram seal or the like in which a peeled trace clearly remains is considered. The hologram seal includes a hologram layer, a light reflection layer, and an adhesive layer, and the hologram pattern formed on the hologram layer is configured to be a pattern that is difficult to forge, thereby preventing the seal from being replaced due to fraud. It has become. In this hologram pattern, coherent light (laser light) incident on the surface of the hologram seal enters the light reflection layer through the embossed surface of the hologram layer, and is reflected from the light reflection layer to the outside of the hologram seal as hologram interference light. Is formed. Further, when the hologram sticker is peeled off, the hologram pattern does not return to its original shape even if it is re-applied, so that the peeled trace remains reliably. Of course, any seal other than the hodogram seal may be used as long as the trace remains.
[0025]
In the state where the lid 82 is attached to the attachment base 81 as described above, the start winning ball detector 93 and its wiring 94 and the connector 95 for connecting the start winning ball detector 93 and the game control circuit board 87 are provided. Since it is housed and arranged in the space formed by the mounting base 81 and the lid 82, they cannot be touched from the outside. For this reason, an unauthorized circuit board cannot be interposed in the middle of the wiring 94 connecting the start winning ball detector 93 and the game control circuit board 87. If an attempt is made to interpose an unauthorized circuit board, the lid 82 must be removed from the mounting base 81. However, if the lid 82 is removed, the trace remains on the seal seal 102, so that illegal acts may occur. You can easily see if it was done. In addition, since the lid 82 is formed of a transparent synthetic resin, the wiring 94 and the connector 95 portion of the start winning ball detector 93 can be easily visually recognized from the outside, so that an unauthorized circuit board is temporarily provided in this portion. If so, it can be easily discovered from the outside. It should be noted that the transparent portion of the lid 82 does not necessarily have to be the whole, for example, only the portion where the start winning ball detector 93, the wiring 94, and the connector 95 can be visually recognized (the ROM must also be visible). good.
[0026]
Next, the mounting base 110 for mounting the above-described substrate storage box 80 to the mechanism plate 50 will be described with reference to FIG. As shown in FIG. 3, the mounting base 110 is made of a rectangular plate made of synthetic resin (or metal), and a pair of engagement rails 111 having an inverted L-shaped cross section are arranged at a predetermined interval at the center of the substrate. It is laid down. The direction in which the engagement rail 111 is provided is the left-right direction along the long side portion of the mounting base 110. Guide pieces 112 that are orthogonal to the substrate surface project from the long side portions (front and rear end edges) of the mounting base 110. A release lever 114 that is elastically deformed is formed at the right end of the mounting base 110, and a base that engages with a locking hole (not shown) formed in the mounting base 81 at the base of the release lever 114. A mating projection 113 is projected. Further, a stop hole 115 for screwing the mounting base 110 to the mounting boss 116 on the mechanism plate 50 side is formed in the board surface of the mounting base 110.
[0027]
Thus, the mounting base 110 is fixed to a predetermined portion on the mechanism plate 50 by being screwed to the mechanism plate 50 via the stop hole 115 and the mounting boss 116. When the board storage box 80 is attached to the mounting base 110, the box 80 is slid from the left side of the mounting base 110. At this time, the engagement rail 111 on the mounting base 100 side is engaged with the engagement rail 83 on the box 80 side, and the guide piece 112 guides the sliding movement of the box 80. Then, the sliding movement of the box 80 causes the release lever 114 on the mounting base 110 to be elastically deformed downward. Finally, the locking hole on the box 80 side engages with the engagement protrusion 113 on the mounting base 110 side. Thus, the mounting of the box 80 is completed. On the other hand, when removing the substrate storage box 80 from the mounting base 110, the release lever 114 is pushed downward to release the engagement between the locking hole and the engagement protrusion 113, and the box 80 is slid to the left from this state. Easy to remove. That is, the substrate storage box 80 is configured to be detachable from the mounting base 110 fixed to the mechanism plate 50 with screws.
[0028]
In the state where the substrate storage box 80 is attached to the mechanism plate 50 as described above, the hitting ball that has won the start winning opening 43 is guided to the ball passage 90 formed in the substrate storage box 80, and the start winning ball. The detector 93 is activated. Referring to FIGS. 2 and 4, this configuration will be described with reference to FIG. 2 and FIG. 4, a communication passage 124 is formed in the winning ball collecting cover body 52 on the back surface corresponding to the position where the start winning opening 43 is arranged. The upper ball guide passage body 120 is attached to the rear end opening so as to communicate therewith. The upper ball guide passage body 120 is formed by closing the open surface of the first component member 121 formed of a conductive synthetic resin or a normal synthetic resin in a U shape with a flat plate-like second component member 122. It is configured as a square-shaped passage body, and is fixed by fixing an attachment piece 123 (see FIG. 2) formed on the base portion to the back surface of the winning ball collective cover body 52. The end of the upper ball guide passage body 120 is bent at a substantially right angle so as to face the upper end of the ball passage 90.
[0029]
On the other hand, a lower ball guide passage body 130 is attached at a position corresponding to a notch opening 99 (the notch opening 99 is formed on the lower side wall of the mounting base 81) facing the lower end opening of the ball passage 90. ing. The lower ball guide passage body 130 is formed by closing the open surface of the first component member 131 formed of a conductive synthetic resin or a normal synthetic resin in a U shape with a flat plate-like second component member 132. It is configured as a passage body having a square cross section, and is fixed by fixing an attachment piece 133 (see FIG. 2) formed on the base thereof to the back surface of the mechanism plate 50. The end of the lower ball guiding passage body 130 is located above the winning ball collecting basket 74 that guides all of the winning balls generated by projecting to the lower portion on the front side of the mechanism plate 50 to the winning ball processing device 60. It communicates with an outlet 134 established at The end of the lower ball guide passage body 130 does not necessarily face the mechanism plate 50. For example, the lower ball guide passage body 130 may face the winning ball collecting cover body 52, and is finally guided to the winning ball collecting rod 74. Just do it.
[0030]
When the board storage box 80 is attached to the mechanism plate 50, the ball hitting the start winning port 43 is located in the board storage box 80 via the communication path 124 and the upper ball guide path body 120. 90, the start winning ball detector 93 facing the middle of the ball passage 90 is actuated, and then released to the winning ball collecting rod 74 of the mechanism plate 50 through the lower ball guiding passage body 130. The predetermined prize ball is paid out by being guided to the winning ball processing device 60.
[0031]
As described above, the configuration and operation of the present embodiment have been described. According to the present embodiment, the board storage box 80 guides the hit ball that has won the start winning opening 43 and the start winning ball detector 93 faces. While forming the ball passage 90, the start winning ball detector 93 and the connection portion between the start winning ball detector 93 and the game control circuit board 87 are provided inside the board storage box 80 in a state visible from the outside. Therefore, since the start winning prize detector 93 and the connector 95 which is the connection part of the wiring 94 are inside the board storage box 80, it is difficult to interpose an unauthorized circuit board in the middle of the board storage box 80. Even if it is known, since the start winning ball detector 93, the wiring 94, and the connector 95 can be visually recognized from the outside, it is possible to easily discover whether fraud has been performed.
[0032]
The board storage box 80 includes a mounting base 81 for storing the game control circuit board 87 and a lid 82, and a seal seal 102 that can easily recognize that the mounting base 81 and the lid 82 have been removed. Therefore, it becomes difficult to attach the unauthorized circuit board to the start winning ball detector 93, the wiring 94, and the connector 95 existing in the board storage box 80, and the sealing seal 102 is temporarily damaged. If so, there is a high possibility that the cheating has been performed, and the cheating can be easily detected.
[0033]
In the above-described embodiment, the sealing seal 102 is exemplified as a sealing means for sealing the mounting base 81 and the lid 82 of the substrate storage box 80. However, the function of the sealing seal 102 is as follows. It can be easily understood from the trace that the lid body 82 has been removed, but a sealing means that makes it difficult to remove the mounting base 81 and the lid body 82 may be used. As such sealing means, there are a welded portion 105 shown in FIG. 5 and a one-way screw 140 shown in FIGS. 6 and 7. FIG. 5 is a cross-sectional view schematically showing the welded portion 105 as a sealing means between the mounting base 81 and the lid 82, and FIG. 6 is a one-way screw 140 as a sealing means between the mounting base 81 and the lid 82. FIG. 7 is a drawing for explaining the operation of the one-way screw 140.
[0034]
In FIG. 5, when the mounting base 81 and the lid 82 are sealed by the welded portion 105 as a sealing means, the portion of the guide rib 100 that is the contact portion between the mounting base 81 and the lid 82 is made of a solvent. A welding part 105 is formed by applying ultrasonic waves by a welding or ultrasonic welding apparatus (not shown) to thermally weld the contact part. In this case, since the attachment base 81 and the lid 82 cannot be removed unless the welded portion 105 is destroyed, it is difficult to remove them, and if they are destroyed, there is a probability that an illegal act has been performed. High and cheating can be easily detected.
[0035]
On the other hand, as shown in FIG. 6, the one-way screw 140 as a sealing means is inserted into a through hole 82 a drilled in the lid body 82 and screwed into the mounting hole 81 a of the mounting base 81. The mounting base 81 can be sealed. In this case, the one-way screw 140 is a special screw that rotates only in the screw tightening direction, and once tightened, it cannot be removed unless the screw is destroyed. Specifically, as shown in FIGS. 7A and 7B, a screw groove provided in the head 141 is composed of an abutment surface portion 142, a concave portion 143, and a central hole portion 144. 7C and 7D, when the screw 140 is tightened with the special minus driver 145, the central shaft portion 146 of the driver 145 is inserted into the central hole portion 144, and from this state, the contact piece of the driver 145 The part 147 is brought into contact with the contact surface part 142 and the head 141 is rotated in one direction (clockwise direction in FIG. 7A), thereby tightening the screw 140. On the other hand, when the screw head 140 is rotated by the driver 145 in the other direction (counterclockwise direction in FIG. 7A) to remove the screw 140, the driver 145 enters the recess 143 and slides. The head 141 cannot be rotated and the screw 140 cannot be removed. It is possible to rotate the head 141 in one direction and tighten the screw 140 even with a normal flathead screwdriver. However, like the special flathead screwdriver 145, the central shaft portion 146 is connected to the central hole portion 144 of the one-way screw 140. The tightening operation can be easily performed by inserting and positioning with the one-way screw 140. As described above, even when the one-way screw 140 is used, the attachment base 81 and the lid 82 cannot be removed unless the screw 140 is destroyed. There is a high probability that an act has been performed, and fraudulent acts can be easily detected.
[0036]
If it is difficult to remove the lid 82 and the mounting base 81 due to the welded portion 105 and the one-way screw 140 described above, the inspection of the ROM or the like by the supervisory authority cannot be performed, so this inspection can be performed. In addition, the initial welded portion 105 and the one-way screw 140 fastening portion are structured so as to be easily broken, and at the time of proper inspection, the original welded portion 105 and the one-way screw 140 fastening portion are destroyed and inspected. Alternatively, the welded portion that is formed may be welded or the fastening portion may be fastened with the one-way screw 140 so that an inspected proof seal can be attached to the broken portion. That is, a structure that can be fixed multiple times may be used.
[0037]
In the above-described embodiment, the ball passage 90 is formed so as to penetrate the central portion of the substrate storage box 80. However, the ball passage 90 may be formed along the outer periphery of the substrate storage box 80. Further, although the substrate storage box 80 is detachably attached to the mechanism plate 50 via the mounting base 110, the structure is such that the substrate storage box 80 can be directly attached to the attachment portion formed on the mechanism plate 50. Things can be used. In this case, a detachable material may be attached, but it is difficult to attach the mechanism plate 50 and the substrate storage box 80 in order to prevent unauthorized replacement of the entire substrate storage box 80 with similar objects. It is good also as a structure (for example, above-mentioned one-way screw etc.).
