Description

  The present invention relates to a gaming machine represented by a pachinko machine or a slot machine, and more particularly to a gaming machine including a board case that can accommodate a control board.

Some conventional gaming machines contain a control board for controlling various kinds of games in a board case. This type of substrate case is a substrate unit provided with a plurality of sealing mechanisms (such as a sealing portion and a sealing member), and is sealed by sequentially using the plurality of sealing mechanisms.
That is, a substrate unit having a first case and a second case and having a circuit board provided therein, and a plurality of first sealing portions provided on the first case side, and on the second case side A plurality of second sealing portions provided, and a plurality of sealing members for sequentially connecting the first sealing portion and the second sealing portion, and at least one of the first sealing portions is provided by the sealing member. When the sealing part and the second sealing part are connected, when the circuit board is taken out, it is necessary to destroy the board unit or cut a predetermined part.

  As described above, the plurality of sealing mechanisms (the first sealing portion, the second sealing portion, and the sealing member that connects them) are provided when there is a trace when the fraudster illegally takes out the control board. The rest is to make it easier to find out that fraud has been done when the branch confirms later, and by using multiple sealing parts individually, multiple opening and closing operations are possible. Yes. For example, when inspecting by an inspection organization such as a supervisory government office, the currently sealed sealing mechanism is destroyed and the substrate case is opened, and after the inspection, the substrate case is again opened using an unused sealing mechanism. It can be sealed. Then, the number of inspections is left as a history, and it is determined whether or not the sealing mechanism has been destroyed by an unauthorized act by comparing the number of inspections with the number of sealed sealing mechanisms. Note that the fraudulent act is performed for the purpose of exchanging a ROM storing a legitimate control program with a ROM storing a fraudulent control program.

  The thing with the same structure was used for all the 1st sealing parts and 2nd sealing parts, and the sealing member which connects these until now. Such a board unit is opened and closed by the inspection of the supervisory authority mentioned above, and is not opened and closed unnecessarily, so it is rarely used up all of the plurality of sealing portions. When the machine is discarded or replaced with another substrate unit, a lot of sealing members are left. Therefore, the fraudster forges the substrate unit (first case and second case) and uses the surplus sealing member to open the sealing member so that the initial sealing state appears. It is conceivable to perform a disguise to conceal what has been done, and the sales office will not notice any abnormality at first glance, and will not be able to find it, or it will be damaged because the discovery is delayed.

  The present invention was devised in view of such problems, and an object thereof is to prevent unauthorized opening (ROM replacement) by using a counterfeit board unit and using an excess sealing member. .

The gaming machine according to the present invention is
A board unit having a first case and a second case and having a circuit board provided therein, a plurality of first sealing portions provided on the first case side, and provided on the second case side A plurality of second sealing portions, and a sealing member that connects the first sealing portion and the second sealing portion, and at least a pair of the first sealing portion and the first sealing member by the sealing member. In a gaming machine equipped with a board unit that needs to destroy the board unit or cut a predetermined part when taking out the circuit board when two sealing parts are connected,
Among the plurality of first sealing portions and the plurality of second sealing portions, at least one pair of the first sealing portion and the second sealing portion that are used for the first time is replaced with another first sealing portion and a second sealing portion. Consists of a special sealing structure different from the sealing structure of the stopper,
Among the sealing members that connect the first sealing portion and the second sealing portion, at least one of the sealing members is configured with a special sealing member that conforms to the special sealing structure,
The substrate unit is sealed by connecting the first sealing portion and the second sealing portion of the special sealing structure by the special sealing member.

  According to the present invention, in the unlikely event that the substrate case itself is improperly formed, and the sealing member of another discarded or destroyed base case is used, the initial sealing is broken. If the sealing member of the initial sealing is of a special structure and cannot be easily obtained even if it is attempted to perform disguise in a state that has not been done, it is highly sophisticated assuming the molding of such a case. Impersonation can be avoided in advance.

In explaining the present invention, the following vocabulary is clarified.
The special sealing member suitable for the special sealing structure is a shape held by each sealing part so that it cannot be removed from the outside in a state where the first sealing part and the second sealing part are connected. Say what you have.
The plurality of sealing portions are usually provided in a number of 5 to 6 so that the opening and sealing of 4 to 5 times can be repeated. Things are included.
In the sealing of the substrate unit, two sealing portions may be used in the initial sealing, and in this case, three or more sealing portions are required.
And when using two sealing parts for such first time sealing, these two become a thing of a different structure from another sealing part (and sealing member).
Further, the two sealing portions (and the sealing member) can also have different structures, and three types, four types of sealing portions, and a sealing member can be used. Is possible.
The gaming machine according to the present invention has as means 1,
A board unit having a first case and a second case and having a circuit board provided therein, a plurality of first sealing portions provided on the first case side, and provided on the second case side A plurality of second sealing portions, and a sealing member that connects the first sealing portion and the second sealing portion, and at least a pair of the first sealing portion and the first sealing member by the sealing member. In a gaming machine equipped with a board unit that requires breaking the board unit or cutting a predetermined part when taking out the circuit board when the two sealing parts are connected,
Among the plurality of first sealing portions and the plurality of second sealing portions, at least one pair of the first sealing portion and the second sealing portion that are used for the first time is replaced with another first sealing portion and a second sealing portion. Consists of a special sealing structure different from the sealing structure of the stopper,
Among the sealing members that connect the first sealing portion and the second sealing portion, at least one of the sealing members is configured with a special sealing member that conforms to the special sealing structure,
The first sealing portion and the second sealing portion of the special sealing structure are connected by the special sealing member to seal the substrate unit.
According to the present invention, at least a pair of the first sealing portion and the second sealing portion is configured with a special sealing structure different from the sealing structure of the other first sealing portion and the second sealing portion, And, since at least one is made of a special sealing member that conforms to the special sealing structure, by any chance, the substrate case itself is improperly molded, and other discarded or Using the sealed base case sealing member, even when trying to disguise the state where the initial sealing is not broken, the initial sealing member is of a special structure, If it is not easily available, it is possible to avoid a high level of camouflage premised on molding such a case.

Means 2: In the gaming machine according to Means 1,
When two pairs of the first sealing portion and the second sealing portion are used for the initial sealing, the two pairs are configured differently from the other first sealing portions and the second sealing portions. Features.
Thus, by using two pairs of the first sealing portion and the second sealing portion for the initial sealing, the sealing can be ensured and two sealing members corresponding to these can be prepared. Otherwise, even if the case is camouflaged, the initial sealed state cannot be revealed and fraud can be prevented more reliably.

Means 3: In the gaming machine according to Means 1,
When two pairs of the first sealing portion and the second sealing portion are used for the initial sealing, each of the two pairs has a structure different from that of the other first sealing portion and the second sealing portion. The pairs are different in structure.
In this way, two pairs of the first sealing portion and the second sealing portion are used, and they are not only different from the structures of the other plurality of first sealing portions and second sealing portions, but also different from each other. Due to the structure, the fraudster has to prepare two special types of sealing members, and this imitation is almost impossible, and even if the case is improperly molded, the initial seal is released. It is possible to more reliably prevent fraudulent acts that appear to be not.

Means 4: In the gaming machine according to Means 1,
The sealing member used for the initial sealing is composed of a synthetic resin-molded sealing pin having elasticity, and the first sealing portion and the second sealing portion store and release the sealing pin. It is configured to be impossiblely engaged.

Means 5: In the gaming machine described in means 1,
The sealing member used for the initial sealing is composed of a sealing pin of a mechanical element having a spring, and the first sealing portion and the second sealing portion cannot be released by storing the sealing pin. It is comprised so that it may engage with.
In this way, by using a special sealing pin having a mechanical element with a spring, it is possible to make it impossible to forge the sealing pin itself, and different sealing members are accommodated in the camouflaged case. Even if it seems that the initial sealing is not broken, such a special mechanical sealing pin can be easily found from the outside when it is not used.

Means 6: In the gaming machine described in means 1,
The sealing member used for the initial sealing is made of a plastically deformable member, and the member is plastically deformed to engage the first sealing portion and the second sealing portion in an unreleasable manner. It is characterized by being.
In this way, the plastically deformable member is a unique part, and once the sealing is performed, the plastic deformation is not restored. For example, even if it is attempted to divert the sealing member from the discarded substrate unit, it cannot be reused. And this situation can be avoided.

Means 7: In the gaming machine described in means 1,
The sealing member used for the initial sealing is composed of a plastically deformable metal tubular member, and the first sealing portion and the second sealing portion are configured to accommodate the tubular member. The tubular member is plastically deformed by screwing the screw into the tubular member, and the first sealing portion and the second sealing portion are engaged so as not to be released. To do.
As described above, since the plastic-deformable metal tubular member is a unique part, it is difficult to prepare it in advance, and therefore, the dishonest act of impersonating the initial sealing by impersonation molding of the substrate case is performed. It is not possible, and prevention can be further ensured.

In addition, the gaming machine according to the present invention is
A board unit having a first case and a second case and having a circuit board provided therein, a plurality of first sealing portions provided on the first case side, and provided on the second case side A plurality of sealing members for connecting the first sealing portion and the second sealing portion, and at least a pair of the first sealing portion and the second sealing portion. In a gaming machine equipped with a board unit that requires breaking the board unit or cutting a predetermined part when taking out the circuit board when the part is connected by the sealing member,
The substrate unit is in a position where the first sealing portion and the second sealing portion face each other in a closed state in which contact with the inside is difficult, and is inserted by the first sealing portion and the second sealing portion. A part is formed, and the first sealing part and the second sealing part are connected by inserting the sealing part into the insertion part,
Among the plurality of first sealing portions and the plurality of second sealing portions, at least a pair of the first sealing portion and the second sealing portion are connected to other first sealing portions and second sealing portions. Consists of a special sealing structure different from the sealing structure,
Of the sealing portions, the number of the first-stage sealing members corresponding to the combination of the first and second sealing portions of the special sealing structure is formed by the first and second sealing portions of the special sealing structure. As a special sealing member that is inserted into the inserted portion and that is plastically deformed, the removal from the outside is restricted and the connection between the first and second sealing portions is maintained. ,
Among the sealing members, the sealing members other than the special sealing member are configured in a shape that does not engage with the first and second sealing portions of the special sealing structure,
At least the first and second sealing portions of the special sealing structure are connected by the special sealing member, and are formed by the first and second sealing portions in a state where the special sealing member is plastically deformed. Housed in the inserted insert,
It is characterized by that.
This gaming machine is a gaming machine in which a special sealing member is used (the front part is used when there are a plurality of special sealing members) and the board unit is in a sealed state. The present invention relates to a type of gaming machine in which an insertion portion is formed by a sealing portion.
Therefore, even if a spare sealing member is left, it cannot be inserted into the first and second sealing parts of the special sealing structure in the counterfeit substrate unit or is not held in the insertion part even if inserted. Therefore, it cannot be sealed.
In addition, the special sealing member is deformed when the sealing portions are connected, and is difficult (or impossible) to be restored, so that it cannot be used again. For example, the special sealing member used for a base unit that has been disposed of is discarded. Inconveniences such as diverting the stop member can be avoided.

  Hereinafter, embodiments of a gaming machine according to the present invention will be described with reference to the drawings. In the following embodiments, a pachinko machine will be described for the sake of convenience, but the present invention includes a ball ball machine other than a pachinko machine (for example, an arrange ball machine, a sparrow ball game machine, etc.), a slot machine, and a pachinko machine. The present invention can be applied to a multi-function machine (for example, a slot machine that uses a game ball as a game medium) combined with a slot machine, and other various game machines (for example, a so-called arcade game machine installed in a game center).

(Front configuration of pachinko machine)
FIG. 1 is a front view of the pachinko machine 10 of the present embodiment, and FIG. 2 is a perspective view showing a state in which the inner frame 12 and the front frame set 14 are opened with respect to the outer frame 11. However, FIG. 2 shows a state in which the lower plate unit 13 is removed from the inner frame 12 for convenience.

  As shown in FIGS. 1 and 2, the pachinko machine 10 includes an outer frame 11 that forms an outer shell of the pachinko machine 10, and an inner frame 12 that is supported on one side of the outer frame 11 so as to be opened and closed. ing. The outer frame 11 is formed in a rectangular shape as a whole by a wooden plate material, and each plate material is assembled by a detachable fastener such as a small screw. The outer frame 11 may be made of light metal such as resin or aluminum in order to reduce the weight. The opening / closing axis of the inner frame 12 is set to extend vertically on the opposite side of the game ball launching handle 18 installation position (left side of the pachinko machine 10 in FIG. 1) as seen from the front of the pachinko machine 10. The inner frame 12 can be sufficiently opened to the front side with an axial center. The inner frame 12 is made of a synthetic resin, specifically, ABS (acrylonitrile-butadiene-styrene) resin. By doing so, the advantages of high viscosity and high impact resistance and low cost production are exhibited.

  The configuration of the inner frame 12 will be described in detail with reference to FIG. FIG. 3 is a front view showing a state in which the front frame set 14 is removed from the pachinko machine 10 (however, in FIG. 3, for the sake of convenience, the configuration in the game castle on the surface of the game board 30 (nails, center accessory, etc.) is shown. (Indicated by white space).

  The inner frame 12 is roughly divided into a lower tray unit 13 attached to the lowermost portion thereof, and an opening / closing axis on the left and right sides of the inner frame 12 in the upper range of the lower tray unit 13 as an axis. A front frame set 14 that is freely attached, a resin base 20 to be described later, and a game board 30 that is attached to the rear side of the resin base 20 are provided.

  The lower plate unit 13 is fixed to the inner frame 12 with a fastener such as a screw. On the front side of the lower tray unit 13, a lower tray 15, a ball release lever 17, a game ball launching handle 18, an ashtray 22, and a sound output port 24 are provided. The lower tray 15 serving as a ball receiving tray is provided at a substantially central portion of the lower tray unit 13 and serves to stop a game ball discharged from the outlet 16 when the upper tray 19 described later becomes full. There is. The ball removal lever 17 is for removing a game ball in the lower plate 15. By moving the ball removal lever 17 to the left in FIG. 1, a predetermined position on the bottom surface of the lower plate 15 is opened, The game ball stopped in the tray 15 can be discharged through the opening on the bottom surface of the lower tray 15 to the player's ball storage box (dollar box). The game ball launching handle 18 is disposed so as to protrude to the front side on the right side of the lower plate 15.

  In accordance with the operation of the game ball launch handle 18 by the player, the game ball is driven toward the game board 30 by the game ball launch device 38 (see FIG. 6). The game ball launching device 38 includes a game ball launching handle 18, a set handle 228, which will be described later, a launching motor 229 (see FIG. 6), and the like. The sound output port 24 is an output port for outputting sound from a speaker (not shown) provided in the lower plate unit 13 or on the back surface. The ashtray 22 is provided on the left side of the lower plate 15. The right side of the ashtray 22 is supported by the lower plate 15 so as to rotate about the axis in the left-right direction (horizontal direction) as an axis (for example, forwardly toward the front side).

  Note that most of the lower dish unit 13 is molded of ABS resin in the same manner as the inner frame 12. By doing so, it is highly viscous and resistant to impact, and can be manufactured at low cost. In particular, the surface layer forming the lower plate 15 and the front panel portion at the back of the lower plate 15 are molded from flame-retardant ABS resin. For this reason, this part is hard to burn.

  As shown in FIG. 2, the front frame set 14 is attached to the inner frame 12 so as to be openable and closable. Like the inner frame 12, the front frame set 14 has an open / close axis extending vertically to the left when viewed from the front of the pachinko machine 10. It can be opened to the front side with an axial center. Moreover, the front frame set 14 is attached so as to fit into the outer wall (rib) 12B (see FIG. 3) of the inner frame 12. That is, since at least a part of the side surface of the front frame set 14 is attached so as to fit into the outer wall (rib) 12B of the inner frame 12, foreign matter (from the gap between the inner frame 12 and the front frame set 14) Such as a needle shape or a thin plate shape, specifically, a fraudulent act such as inserting a wire, piano wire, celluloid plate, etc.) can be prevented. Further, since the front frame set 14 is made of a synthetic resin, specifically, an ABS resin, like the inner frame 12, the front frame set 14 is highly viscous and resistant to impact, and can be manufactured at low cost.

  On the other hand, an upper plate 19 (see FIG. 1) as a receiving tray for game balls is provided integrally with the front frame set 14 at a lower portion of the front frame set 14 (above the lower plate 15 described above). The upper tray 19 is a ball receiving tray for temporarily storing the game balls and guiding them to the game ball launching device 38 while aligning them in a line. Similar to the lower plate 15, the upper plate 19 has a structure in which the surface layer is formed of flame-retardant ABS resin.

  As shown in FIG. 3, the inner frame 12 is mainly composed of a resin base 20 having a rectangular outer shape, and a substantially circular window hole 21 is formed at the center of the resin base 20. A game board 30 is detachably mounted on the rear side of the resin base 20. The game board 30 is made of a rectangular plywood, and is attached in a state in which the peripheral edge thereof is in contact with the back side of the resin base 20 (inner frame 12). Accordingly, a substantially central portion of the front surface portion of the game board 30 is exposed to the front surface side of the inner frame 12 through the window hole 21 of the resin base 20.

  Next, the configuration of the game board 30 will be described with reference to FIG. FIG. 4 is a front view showing the configuration of the game board 30. The game board 30 is a tenth prize opening 610, a general prize opening 600, a pair of left and right first start openings 601, a deformed portion of the first start openings 601, and provided at a position slightly below the first start openings 601. 2 A start port 602, an electric accessory unit (center accessory) 603 provided substantially in the center of the game area, and the like. The general winning port 600, the first starting port 601, the second starting port 602, the electric accessory unit 603, etc. are disposed in the respective through holes formed by the router processing in the game board 30, respectively. 30 It is attached from the front side with wood screws or the like. The parts corresponding to the above-mentioned winning prize opening 610, the general winning opening 600, the first starting opening 601, and the second starting opening 602 are respectively the winning entry entrance entrance sensor 609, the general winning entry entrance entrance sensor 607, A first start port entrance sensor 605 and a second start port entrance sensor 606 are provided, and these sensors are connected to a main control board (main control device) to be described later through an electric wiring (not shown). When a game ball enters the winning prize opening 610, the general winning opening 600, the first start opening 601, the second start opening 602, and the electric accessory unit 603, it is detected by each of the detection sensors described above. Based on the sensor output, a predetermined number of prize balls are paid out to the upper plate 19 (or the lower plate 15).

  The detection results detected by the winning detection mechanism are taken into a main control board, which will be described later, and a payout command (the number of game balls to be paid out) according to the winning situation is issued from the main control board. Sent to the board. Then, a predetermined number of game balls are paid out by the output of the payout control board. In such a case, a conventional method (so-called evidence ball method) in which game balls won in various winning openings are once collected in a winning ball processing device and paid out after the winning ball processing device confirms the presence of winning balls one by one in order. Unlike the above, in the pachinko machine 10 according to the present embodiment, the winning of a game ball is electrically detected for each winning opening and the payout is immediately made (that is, the winning ball processing apparatus is abolished in the pachinko machine 10). doing). Therefore, even if there are a lot of game balls to be paid out, the payout can be carried out quickly. However, the conventional “evidence ball system” may be applied to the present invention.

  In addition, a decoration member 630 having the general prize opening 600 is provided at the left and right ends of the game board 30, while the first start port 601 and the second start port 602 are provided below the game board 30. An auxiliary unit 608 is provided. Further, the game board 30 is provided with an out port 36 so that game balls that have not entered the various winning devices etc. are guided through the out port 36 toward a ball discharge path (not shown). It has become. Further, the game board 30 is provided with a large number of nails and a windmill having a similar function in order to appropriately disperse and adjust the falling direction of the game balls.

  Further, the game board 30 is provided with a rail unit 50 for guiding the game ball launched from the game ball launching device 38 to the upper part of the game board 30, and is launched in accordance with the turning operation of the game ball launch handle 18. The played game balls are guided to a predetermined game area through the rail unit 50. The rail unit 50 is formed of a ring-shaped resin molded product (for example, a molded product added with fluororesin), and has an inner rail 51 and an outer rail 52 that are integrally formed in an inner and outer double. . In addition, since the rail unit 50 is shape | molded by adding a fluororesin, it can reduce the frictional resistance of the game ball about the back surface 50A shown in FIG. The inner rail 51 is formed in a substantially annular shape except for about ¼ of the upper portion, and an outer rail 52 is formed so that a part (mainly the left side) faces the inner rail 51. In such a case, a guide rail is constituted by the inner rail 51 and the outer rail 52, and a spherical guide passage is formed by a portion (the left portion facing) where the rails 51 and 52 are parallel to each other at a predetermined interval. The ball guide passage is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened.

  A return ball preventing member 53 is attached to the tip of the inner rail 51 (upper left portion in FIG. 4). This prevents a situation in which the game ball once guided from the ball guide path between the inner rail 51 and the outer rail 52 to the upper part of the game board 30 returns to the ball guide path again. Yes. Further, a return rubber 54 is attached to the outer rail 52 at a position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 4: a portion corresponding to the tip portion of the outer rail 52). Accordingly, the game ball fired at a predetermined momentum or more hits the return rubber 54 and rebounds. On the inner surface of the outer rail 52, a sliding plate 55 (as a long metal strip made of stainless steel) is used to make the flight of the game ball smoother, that is, to reduce the frictional resistance of the game ball. 3) is attached.

  An arc-shaped flange 56 projecting outward is formed on the outer peripheral portion of the rail unit 50. The flange 56 constitutes a mounting surface for the game board 30. When the rail unit 50 is attached to the game board 30, the flange 56 is brought into contact with the game board 30, and in this state, screws or the like are inserted into a plurality of through holes formed in the flange 56. The rail unit 50 is fastened to 30. In the present embodiment, in order to firmly fasten at least the left side of the rail unit 50 to the game board 30, the left side of the rail unit 50 is fastened to the game board 30 with more screws than the right side. The adhesion to the game board 30 on the left side can be improved, and the ball flying of the game ball can be improved. This is because if the left side of the rail unit 50 is wobbled with respect to the game board 30, the momentum of the game ball emitted to the rail unit 50 is absorbed by the wobble.

  Further, in the present embodiment, the top, bottom, left, and right ends of the rail unit 50 are formed substantially linearly (flatly) when viewed from the front. That is, the flange 56 is cut off at each of the upper, lower, left and right ends of the rail unit 50, and the rail diameter can be expanded in a limited area in the pachinko machine 10, that is, the game area on the game board 30 can be expanded. ing.

  A convex portion 57 is formed at the entrance of the ball guide passage between the inner rail 51 and the outer rail 52 so as to close a part of the ball guide passage. The convex portion 57 is provided in a substantially vertical direction from the inner rail 51 to the lower end portion of the rail unit 50, and a foul ball that does not reach the game area and flows backward in the ball guide passage is used as a foul ball passage 63 (see FIG. 3). Play a role in guiding. Note that the lower right corner and the lower left corner of the game board 30 are spaces for sticking stickers (S1 and S2 in FIG. 4) and plates such as certificate stamps (for example, serial numbers are described). In order to secure this adhering space, notches 58 and 59 are formed in the flange 56. By sticking a seal such as a certificate (S1, S2 in FIG. 4) to the lower right corner or the lower left corner of the game board 30, the game board 30 and the certificate can be uniquely defined.

  Next, the game area will be described. The game area is partitioned and formed in a substantially circular shape by the inner periphery (inner and outer rails) of the rail unit 50. In the present embodiment, the game area is an area excluding the area of the guide rail that is a parallel part of the inner and outer rails 51 and 52 among the area surrounded by the inner rail 51 and the outer rail 52 when viewed from the front of the pachinko machine 10. It is said. Therefore, when it is referred to as a game area, the guide rail portion is not included, and the left limit position toward the game area is specified not by the outer rail 52 but by the inner rail 51. Similarly, the right limit position toward the game area is specified by the inner rail 51. Further, the lower limit position of the game castle is specified by the lower end position of the game board 30. Further, the upper limit position of the game area is specified by the outer rail 52.

  Returning to the description of FIG. 3, in the resin base 20, below the window hole 21 (game board 30), a launch rail 61 for guiding the game ball immediately after being launched from the game ball launcher 38 is attached. ing. The firing rail 61 is fixedly attached to the resin base 20 via a metal plate 62 behind the firing rail 61, and is configured to extend linearly at a predetermined firing angle (launch angle). Accordingly, the game ball that is launched in accordance with the turning operation of the game ball launching handle 18 is first launched obliquely upward along the launch rail 61, and thereafter, into the predetermined game area through the ball guide path of the rail unit 50 as described above. Guided.

  Further, there is a gap of a predetermined interval between the firing rail 61 and the rail unit 50 (guidance rail), and a foul ball passage 63 is formed below the gap. Therefore, if the game ball launched from the game ball launching device 38 does not reach the return ball prevention member 53 and returns to the inside of the guide rail as a foul ball, the foul ball passes through the foul ball passage 63 to the lower plate. 15 is discharged.

  When the foul spheres flow backward in the guide rail, most of them flow along the outer rail 52 and drop downward when reaching the lower end of the outer rail 52. However, some foul spheres fall inside the guide rail. There is also a thing that jumps to the inner rail 51 side. At this time, the foul ball that has bounced up hits the convex portion 57 at the entrance of the ball guide passage and is guided to the foul ball passage 63, whereby all of the foul balls are reliably guided to the foul ball passage 63. The interference between the foul ball and the next game ball to be fired is suppressed.

  Although detailed disclosure of the drawings is omitted, game balls are supplied to the game ball launcher 38 one by one from the ball outlet on the front frame set 14 side (the ball outlet leading from the most downstream portion of the upper plate 19). . Further, the game ball launching device 38 is provided with a ball striking ball, and the game ball is launched with the rotation of the ball striking center around the shaft portion.

  A reference numeral 67 in FIG. 3 is a discharge port communicating with the upper plate 19, and the game ball is discharged to the upper plate 19 through the discharge port 67. The discharge port 67 is provided with an openable / shutterable shutter 68 that is displaced in a substantially horizontal state and a substantially vertical state about a rotation axis in a substantially horizontal direction. The front frame set 14 is opened from the inner frame 12. In the performance (state of FIG. 3), the shutter 68 is changed from a substantially horizontal state to a substantially vertical state by an urging force of a spring or the like, and the discharge port 67 is closed so that the game ball does not spill from the discharge port 67. When the front frame set 14 is closed, the shutter 68 is pushed open by a ball passage rod 69 (see FIG. 2) provided on the back surface of the front frame set 14 to be in a substantially horizontal state. The game ball discharged toward the direction passes through the ball passage ridge 69 and is discharged to the upper plate 19 without any leakage. Therefore, in the pachinko machine 10, it is possible to prevent the inconvenience that the game balls in the payout passage and the like spill out of the pachinko machine 10 when the front frame set 14 is opened.

  As shown in FIG. 3, the resin base 20 is provided with a substantially rectangular small window 71 at the lower right portion of the window hole 21. Therefore, a sticker such as a stamp (S1 in FIG. 4) stretched at the lower right corner of the game board 30 can be seen through the small window 71. Further, a sticker or the like can be attached from the small window 71.

  As shown in FIG. 3, support brackets 81 and 82 are attached to the left end portion of the inner frame 12 as a support mechanism for the front frame set 14. The upper support fitting 81 is provided with a support hole 83 having a notch on the front side of the figure, and the lower support fitting 82 is provided with a protruding shaft 84 protruding in the vertical direction.

  As shown in FIG. 3, a front frame set open detection switch 90 that detects that the front frame set 14 is opened with respect to the inner frame 12 is provided above the inner frame 12. When the front frame set 14 is opened, it is output from the front frame set open detection switch 90 to the computer in the hall (in the pachinko shop). When the front frame set 14 is closed, the metal reinforcing plates 131 and 132 of the front frame set 14 shown in FIG. 5 come into contact with the pair of metal fittings 92 of the inner frame 12 shown in FIG. The grounding of the front frame set 14 is secured.

  Here, the front frame set 14 described above will be described in more detail with reference to FIGS. FIG. 5 is a rear view of the front frame set 14. The front frame set 14 is formed with a substantially elliptical window 101 so that most of the game area can be visually recognized from the outside. Specifically, the window portion 101 has a shape in which a substantially central portion on the left and right sides is curved relatively gently as compared with the upper and lower sides. The substantially central portion may be linear.

  Further, the shortest distance between the left end of the window portion 101 and the left end of the front frame set 14 when viewed from the front of the pachinko machine 10 (the left-right width of the so-called left side frame portion: shown on the right side in FIG. 5), The frame width on the opening / closing axis side is set to be relatively large in order to increase the strength and support strength of the front frame set 14 itself. In this case, as apparent from comparison between FIGS. 1 and 3, in the state where the front frame set 14 is closed, not only the left end portion of the outer rail 52 but also the left end portion of the inner rail 51 is the left frame portion. Obscured by. That is, at least a part of the guide rail overlaps and is covered with the left frame portion of the front frame set 14 when viewed from the front of the pachinko machine 10. Even if it becomes difficult to visually recognize the game ball in this way, it is only a passing point where the game ball is guided to the game area, and it is difficult to see the game ball in a game castle where the player mainly enjoys the game. It does n’t mean that. Therefore, there is no trouble in actual game. Moreover, while such a trouble does not arise, sufficient intensity | strength and support strength of the front frame set 14 are securable.

  In addition, the front frame set 14 is provided with light emitting means such as various lamps around it (for example, a corner portion). These light emitting means play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state in the big hit game state or when the blade is opened. For example, at the periphery of the window portion 101, an annular illumination portion 102 containing a light emitting means such as an LED is provided symmetrically, and at the center of the annular illumination portion 102 and at the top of the pachinko machine 10, Similarly, a central illumination unit 103 having a built-in light emitting means such as an LED is provided. In the pachinko machine 10, the central illumination unit 103 functions as a jackpot lamp, and lights and blinks during the jackpot gaming state to notify that the jackpot gaming state is in progress. Further, the upper plate 19 is also provided around the upper plate 19 with an upper plate illumination unit 104 having a built-in light emitting means such as an LED.

  In addition, on the left and right sides of the central illumination unit 103, there are provided a prize ball lamp 105 that is lit during the payout of a prize ball and an error display lamp 106 that is lit when a predetermined error occurs. Further, a small window 107 made of a transparent resin is provided so as to be adjacent to the lower end portion of the annular illumination portion 102 so that a part of the inner frame 12 surface, the game board 30 surface, or the like can be visually recognized. Since the predetermined portion of the small window 107 is flat, the certificate paper or the like attached to the lower right corner of the game board 30 can be suitably read from the flat portion of the small window 107 by a machine.

  In addition, a ball lending operation unit 120 is disposed below the window unit 101, and the ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. When the ball lending operation unit 120 is operated with a bill or a card inserted in a card unit (ball lending unit) (not shown) arranged on the side of the pachinko machine 10, a game ball is lent according to the operation. Done. The ball lending button 121 is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is supplied to the upper plate 19 as long as there is a remaining amount on the card or the like. Is done. The return button 122 is operated when requesting the return of a card or the like inserted into the card unit. The frequency display unit 123 displays remaining amount information such as a card. Note that the ball lending operation unit 120 is not required for a pachinko machine in which a game ball is directly rented from the ball lending device unit to the upper plate without using a card unit, that is, a so-called cash machine. Therefore, a decorative seal or the like is attached to the installation portion of the ball rental operation unit 120. Thereby, the common use of the lending operation unit of the pachinko machine using the card unit and the cash machine can be achieved.

  Further, as shown in FIG. 1, the vicinity of the small window 107 on the left side of the front frame set 14 is not protruded more than necessary to the front side (the front side in FIG. 1). Thus, when a game ball is lent directly to the upper plate 19 from the card sand ball lending device provided on the left side of the pachinko machine 10, the tip of the nose portion (so-called elephant nose) of the ball lending device is discharged. An exit can be suitably located in the upper position of the top plate 19, and the game ball lent from the nose part of the said ball lending apparatus can be received by the top plate 19. FIG.

  Various reinforcing members made of metal are provided on the back side of the front frame set 14 so as to surround the window portion 101. Specifically, as shown in FIG. 5, reinforcing plates 131, 132, 133, and 134 are respectively attached to the back side of the front frame set 14 and on the top, bottom, left, and right sides of the window portion 101. These reinforcing plates 131 to 134 are connected in contact with each other, but resin parts 135 for avoiding direct contact are interposed at the connecting portions of the left and upper reinforcing plates 132 and 133 in the drawing. Thus, since the resin part 135 is interposed in the connection part of the reinforcement boards 132 and 133, it can prevent that a noise loops with the reinforcement boards 131-134. In addition, the right reinforcing plate 131 in FIG. 5 is provided with an engaging claw 131A having a hook shape at an intermediate position thereof, and the engaging claw 131A of the inner frame 12 with the front frame set 14 closed. It is configured to be engaged with the hole 12A (see FIG. 3). With this configuration, the front frame set 14 is configured to include the upper plate 19, and even if the upper and lower pivot support positions are extended, the front frame set 14 can be prevented from being lifted at the intermediate position. Therefore, an illegal act or the like floating the front frame set 14 is suppressed.

  The lower reinforcing plate 134 is provided with a resin rail side wall member 136 at a position facing the firing rail 61 (see FIG. 3). The rail side wall member 136 becomes the side wall of the firing rail 61 when the front frame set 14 is closed. Therefore, the game ball is prevented from spilling from the launch rail 61.

  The reinforcing plates 131 to 134 described above also have a function as a metal frame for supporting the glass, and a part of the reinforcing plates 131 to 134 is folded back to form a glass holding groove. The glass holding grooves are formed in two rows on the front and rear sides, and a pair of front and rear glasses 137 having a rectangular shape are held in each glass holding groove. Thereby, the two glass 137 is attached to the front and back at a predetermined interval.

  Further, support metal fittings 151 and 152 are attached to the right end portion of the front frame set 14 in FIG. 5 (left end portion when viewed from the front of the pachinko machine 10) as a support mechanism for the inner frame 12. Therefore, the front frame set 14 can be opened and closed with respect to the inner frame 12 by assembling the support brackets 151 and 152 on the front frame set 14 side to the support brackets 81 and 82 (see FIG. 3) on the inner frame 12 side.

When the inner frame 12 is opened, it is output from the inner frame opening detection switch 388 to the computer for the hall (in the pachinko parlor).

  As shown in FIG. 8, the back pack unit 203 is detachably attached to the back surface of the inner frame 12 by a fastening hole 240, a ny latch 386, and a fixture 241. Since the fixture 241 is also used in this way, the back pack unit 203 is prevented from being detached from the inner frame 12 due to the weight of the game ball supplied to the tank 355.

  The configuration of the front side and the back side of the pachinko machine has been described above. Next, the most important part relating to the present invention, that is, the substrate case 263 of the main controller 261 will be described in detail. The substrate case 263 is a substrate unit having a first case (case main body 400) and a second case (lid body 500) and having a circuit board provided therein, and is provided on the first case side. A plurality of first sealing parts (main body side sealing part 401), a plurality of second sealing parts (lid side sealing part 501) provided on the second case side, and the first sealing part A sealing member (sealing pin 700) for connecting the second sealing portion, and at least one of the first sealing portion and the second sealing portion is connected by the sealing member. In this case, when taking out the circuit board, the board unit needs to be destroyed or a predetermined part must be cut. In the present invention, not only the substrate case 263 of the main control device 261 but also a sub control device (for example, the display control device, the sound lamp control device 262, the payout control device 311, the launch control device 312, the power control device 313, etc.). However, for the sake of convenience, in the following embodiment, only the case where it is applied to the substrate case 263 of the main controller 261 will be described.

As described above, a plurality of first sealing portions (main body side sealing portion 401) and second sealing portions (lid body side sealing portion 501) are provided, in this case, five, but the first sealing portion is used for sealing. Other than the sealing part, the other parts have the same structure, and at least a pair of the first sealing part and the second sealing that are used for the first time out of the plurality of first sealing parts and the plurality of second sealing parts. The part is configured with a special sealing structure different from the sealing structure of the other first sealing part and the second sealing part.
Therefore, first, the first and second sealing portions having the normal structure and the sealing member thereof will be described with reference to FIGS. 20 to 23. The first and second sealing portions having the normal structure and the second sealing member will be described. The sealing part and its sealing member have a structure known per se.

The case main body 400 that is the first case and the lid body 500 that is the second case are configured to be slid and fitted to each other. A main body side sealing portion 401 as a first sealing portion and a lid side sealing portion 501 as a second sealing portion are formed so as to face each other and correspond to each other.
And as a sealing member which connects the main body side sealing part 401 and the lid side sealing part 501, here, the sealing pin 700 is composed of a first sealing metal fitting 700A and a second sealing metal fitting 700B. The first sealing fitting 700A is set on the main body side sealing portion 401 side, and the second sealing fitting 700B is inserted from the lid side sealing portion 501 and engages with the first sealing fitting 700A. It is configured as follows.

Further, leaf springs 163 and 163 are provided slightly in the center of the first sealing metal fitting 700A, and the leaf springs 163 and 163 protrude on the opposite side of the back hooks 162 and 162. When the first sealing fitting 700A is inserted into the slit S1 of the main body side sealing portion 401 which is the first sealing portion, the back side hooks 162 and 162 and the leaf spring portions 163 and 163 are elastically deformed flat. When the back side hooks 162 and 162 reach the space 156 behind the bridging wall 155 in the state where the inner side hook 155 is moved, the inner side of the slits S1 is elastically deformed and the inner side hooks 162 and 162 are bridged. When it reaches the space 156 in the back of the wall 155, it returns to its original hook shape due to elasticity, and the leaf spring portions 163, 163 press the entire first sealing fitting 700A against the opposing walls 153, 153 and the bridge wall 155. Therefore, the first sealing fitting 700A cannot be extracted from the slit S1. At this time, the front side hook 161 is in a state of being caught by the protrusion 157, and further prevents the first sealing fitting 700A from proceeding to the back of the slit S1. In addition, inclined protrusions 164 and 164 are provided in the first sealing fitting 700A slightly closer to the center. The inclined protrusions 164 and 164 engage with a second sealing metal fitting 700B, which will be described later, in an inseparable state.

Here, referring to the lid-side sealing portion 501 and the second sealing fitting 700B, which are the second sealing portions, the second sealing fitting 700B is obtained by processing a metal plate material into a substantially J-shape. Of the body side sealing part 501, a connecting part connecting the long leg part 91 inserted into the wide side S20A of the rectangular hole S20 partitioned by the bridging part 183 and the short leg part 95 inserted into the rectangular hole S20B.

It is a vertical side view of the principal part which shows the state before sealing is started by the sealing attitude | position of a sealing pin.

As shown in FIGS. 24 to 26, the substrate case 263 serves as a pair of case components, that is, a case main body 400 serving as a first case having a capacity for substantially accommodating the control substrate, and a second case. The lid body portion 500 is included.
Note that the names of the case main body 400 (first case) and the lid body 500 (second case) have already been mentioned in the above solution section, and the lid is closed with respect to the base main body. Although it is a lid | cover, it may close | close with a main body with respect to this as a base, and may be recognized as a relative thing. Accordingly, which of the case body 400 and the first case is referred to as the lid body 500 and the second case may be arbitrarily selected from the viewpoint of the control board storage function or structure. In the present invention, it is called as described above.

The substrate case 263 is divided into two parts, a case body 400 that is a first case and a lid 500 that is a second case, but as shown in FIG. In order to perform the initial sealing using the sealing pin 700, here, one main body side sealing portion 401 serving as a first sealing portion and one lid side sealing serving as a second sealing portion. The sealing mechanism 470 including the portion 501 is configured so that the seal cannot be released. The specific configuration will be described later.

  As a basic configuration, here, one main body side sealing portion 401 at the right end portion is a pin storage space for storing in a preliminary storage posture (see FIG. 29) in which the sealing pin 700 is almost completely buried. The pin housing space 410 includes a pin position restricting portion 420 that is housed in a sealing posture (see FIGS. 30 and 31) that includes the front end engaging portion 451 of the sealing pin 700 and is exposed to the outside of the pin housing space 410. In the sealing posture in which the sealing pin 700 comes into contact with the pin position restricting portion 420, the tip engaging portion 702 is engaged with the lid-side sealing portion 501 so as not to be released. Further, the pin storage space 410 is configured to be able to leave and exit.

  The case main body 400 and the lid body 500 are assembled together to form a storage space for storing a control board (not shown). In this embodiment, as shown in FIGS. 24 and 26, U-shaped engagement grooves 411 and 411 are provided on both side edges of the case main body 400, while both side edges of the lid body 500 are provided. Are provided with fitting protrusions 511 and 511. Then, the case main body 400 and the lid body 500 are assembled by slidingly fitting the fitting protrusions 511 and 511 into the U-shaped engagement grooves 411 and 411.

More specifically, the case main body 400 and the lid body 500 have a fitting protrusion 511 that can be slidably fitted to one of them, and the fitting protrusion 511 on the other side. An engaging groove 411 is provided, and is configured to be opened and closed by sliding the lid body 500 with respect to the case main body 400.
That is, the fitting protrusions 511 and 511 protrude outwardly along the outer sides of the opening edges (openings of the box-like box) of both lateral side walls of the case body 400 which is the one case component. The U-shaped cross-section is formed so that the opening edge of both lateral side walls (opening of the box-shaped cover) of the lid portion 500 which is the other case component protrudes outward from the both lateral side walls. Engagement grooves 411 and 411, and the fitting protrusions 511 and 511 can be slidably fitted into the U-shaped engagement grooves 411 and 411 from the front wall side toward the rear wall side. It is configured.

  As a result, the case main body 400 and the lid body 500 are opened and closed by one fitting protrusion 511 and the other engagement groove 411 into which the fitting protrusion 511 is engaged. , Both the slides can be aligned in a stable position, and in the slide alignment, an accurate contact state of the lid side sealing portion 501 with respect to the distal end engaging portion 702 of the sealing pin 700 described later can be obtained. The expansion / contraction action (downward displacement) of the sealing pin 700 can be surely expressed.

24 to FIG. 26, the main body side sealing portion 401 is provided on the outer side of one side portion of the case main body portion 400, and the lid body side sealing portion 501 is provided on one side of the lid body portion 500. One is provided on the outer side of the side portion and at the right end corresponding to the main body side sealing portion 401. Further, the lid side sealing portion 401 is thicker than the lid portion 500 and can be easily broken. A thin pair of ribs 502 are connected to each other.
Furthermore, as shown in FIGS. 24 to 26, on both outer side portions of the main body side sealing portion 401 of the case main body portion 400, and on both outer side portions of the lid body side sealing portion 501 of the lid body portion 500, Projections having concave grooves that fit together and sealing fitting portions 505 and 405 for the projections that fit into the projections are integrally formed.

  In this way, by providing the fitting portions 405 (protruding bodies) and 505 (concave grooves) for fitting together on both outer sides of the case main body portion 400 and the lid body portion 500, both are slid. When closed by operation, coupled with the above-mentioned fitting between the fitting protrusion 511 and the engaging groove 411, the fitting state of both in the direction perpendicular to the sliding operation direction is made more robust. can do.

  Thus, the case main body 400 and the main body side sealing portion 401, and the lid body portion 500 and the lid body side sealing portion 501 are integrally formed. Here, the case main body 400 and the lid body 500 connect the four main-body-side sealing portions 401 and the lid-side sealing portion 501 having the normal structure described above to positions corresponding to each other. The one main body side sealing portion 401 and the lid side sealing portion 501 have a special structure. As shown in FIGS. 24 to 26, the lid-side sealing portion 501 stores the pin of the body-side sealing portion 401 when the case main body 400 and the lid body 500 are sealed. The space 410 is substantially closed.

  Further, as shown in FIGS. 24 to 26, the lid-side sealing portion 501 includes a pair of protrusions 506 at the tip in the sliding operation direction, and the main-body-side sealing portion 401 is sealed. At this time, a fitting hole 406 for fitting the protrusion 506 of the lid side sealing portion 501 is provided. Here, the protrusions 506 are protruded from both sides of the front end portion of the lid-side sealing portion 501 so as to be firmly fitted, but this may be one, and the position thereof may also be In addition, it may be in the center in the width direction or closer to one side, and conversely, it may have three protrusions like a fork.

  Thus, as shown in FIG. 24 and FIG. 26, the lid side sealing after the lid side sealing portion 501 and the main body side sealing portion 401 are in the fitted state. The position fixing at the portion 501 and the main body side sealing portion 401 is ensured, and the locking state of the lid side sealing portion 501 and the main body side sealing portion 401 by the sealing pin 700 is firmly held without any cracks, The seal can be reliably maintained.

  Furthermore, a rounded surface (shown at an acute angle in the drawing, but in fact, chamfered to form a small-diameter round) is formed on the lower surface of the distal end portion of the lid-side sealing portion 501. In this way, the rounded surface is formed on the lower surface of the distal end portion of the lid-side sealing portion 501 so that the distal end portion of the lid-side sealing portion 501 is exposed from the pin storage space 410 at the time of sealing. When coming into contact with the cam slope 701 of the tip engaging portion 702 of the stop pin 700, the downward displacement operation can be smoothly derived, and the sealing work by the sealing pin can be surely and smoothly performed. The round is equivalent to an arc or a slope (chamfer), and can be appropriately selected and replaced.

Here, the structure of the sealing pin 700 which is a sealing member having a special structure will be described with reference to FIGS.
The sealing pin 700 is manufactured by molding using an elastic synthetic resin, here, polyacetal. The sealing pin 700 is configured by integrally connecting the distal end engaging portion 702 and the base end portion 703 by a pair of curved connecting members 706 exhibiting elasticity (outward). Yes. And the front-end | tip engaging part 702 of the said sealing pin 700 is formed in the cam slope 701 contact | abutted to the inner surface side (R of the lower surface of a front-end | tip part) of the said cover body side sealing part 501 in the one side surface side. The other side surface is formed as a flat locking surface 704, and has a substantially wedge shape as a whole in side view.

  The pin position restricting portion is configured such that the width of the proximal end portion 703 of the sealing pin 700 is larger than the width of the distal end engaging portion 702, and the proximal end of the sealing pin 700 It is configured by providing a step portion at the bottom of the pin storage space that contacts the portion 703 and does not allow lowering, but does not contact the tip engaging portion 702 and has a groove width that allows lowering. It is characterized by being.

  More specifically, as shown in FIGS. 25, 27, and 28, the width W1 of the base end portion 703 of the sealing pin 700 is the groove width of the step portion 421 in the vicinity of the bottom portion of the pin storage space 410. On the other hand, the width W3 of the tip engaging portion 702 of the sealing pin 700 is configured to be smaller than the groove width W2 of the stepped portion 421. When inserted into the pin storage space 410 from the front end engaging portion 702 side, it reaches the inside of the step groove at the bottom of the pin storage space 410 and is completely stored and completely buried (preliminary storage). 29), but when inserted into the pin storage space 410 from the base end 703 side, the base end 703 of the sealing pin 700 is larger than the groove width W2 of the stepped portion 421. Completely fit Not in, the tip engaging portion 702 as described above, will be set within in a state of being exposed upward (sealing position) from the pin storage space 410 (see FIG. 31).

It is the pin position restricting portion 420 that creates this sealing posture. Here, the groove width W2 of the bottom step portion 421 inside the pin storage space 410 described above is set to the base end portion 703 of the sealing pin 700. It is formed by making it smaller than the width W1, and making the width W3 of the tip engaging portion 702 smaller than the groove width W2.
Thus, the groove width W2 of the step portion 421 at the bottom of the pin storage space 410 is configured to be smaller than the width W1 of the base end portion 703 of the sealing pin 700. The preliminary storage posture and the sealing posture can be properly used.

  As described above, the step portion 421 having the groove W2 having a predetermined width is provided in the bottom portion of the pin storage space 410, and the width W1 of the base end portion 703 of the sealing pin 700 is set to correspond to the step portion 421. A simple structure in which the width W3 of the tip engaging portion 702 is configured to be smaller than the groove width W2 of the step portion 421 (molding and sealing of the main body side sealing portion 401 is configured to be larger than the width W3. By forming the retaining pin 700), the sealing pin 700 can be positioned by changing from the preliminary storage posture to the sealing posture, and the sealing function can be exhibited. In addition to the bottom of the pin storage space as shown in the embodiment, the stepped portion may be installed at an appropriate predetermined position in the pin storage space.

  In this way, by forming the cam slope 701 in the tip engaging portion 702 of the sealing pin 700, the sealing pin is brought into contact with the inner surface side of the lid side sealing portion 501 from the state shown in FIG. The expansion and contraction function (downward movement displacement in the storage space) of 700 can be caused more smoothly and reliably, and the other side surface is formed as a flat locking surface 704, thereby locking the lid side sealing portion 501. Can be reliably exhibited as compared with a simple sharp pin.

  The lid-side sealing portion 501 is provided with a fitting recess 505 into which the front end engaging portion 702 of the sealing pin 700 is fitted, as shown in FIGS. 29 to 31. Thus, the engagement state of the distal end engaging portion 702 of the sealing pin 700 with respect to the lid-side sealing portion 501 is ensured by a simple structure in which the insertion recess 505 is formed on the inner surface of the lid-side sealing portion 501. A reliable locking state can be obtained by the engagement piece between the inner surface of the fitting recess 505 and the locking surface 704, and the sealed state can be made firm.

  As shown in FIG. 31, when the sealing pin 700 is positioned in the pin storage space 410 in a sealing posture, the tip engaging portion 702 configured in a substantially wedge shape has the pin storage space 410. Exposed upward. A concave portion 705 is formed below the cam inclined surface 701 of the wedge-shaped portion, but this structure is for saving molding resin, and the base end portions on both sides thereof are the band-shaped connecting members 706. It is connected with. As described above, the structure using the strip-shaped connecting member 706 can be made of a synthetic resin or a metal plate spring as a constituent material of the sealing pin 700, and can stably extract the elasticity. In the case of molding, it is not necessary to fill the gap between the sealing pin 7800 distal end engaging portion 702 and the base end portion 703 with a filling resin, and the molding resin can be saved.

(Modification 1 of a sealing member having a special structure)
Since it is important to make the sealing member used for the initial sealing different from other multiple-use sealing members, unlike the resin-molded sealing member 700 of the previous embodiment, here, the mechanical elements A sealing member 700C having the above is employed to prevent an unauthorized person from imitating more easily. Of course, for the other plurality of sealing portions and sealing members, the structure of the sealing sealing portion and the sealing members (first sealing fitting 700A and second sealing fitting 700B) of the above-described embodiment are used. Yes.
As shown in FIGS. 32 to 33, in this modified example, the sealing pin 700C is different from the above-described embodiment so that the distal end engaging portion 722 can be expanded and contracted with respect to the base end portion 723. First, the difference is that a spring 726 is provided between the two. The coil spring 726 is accommodated in a slightly compressed state in a space formed by the housing 727 and the base end portion 723 serving as a base, and the distal end engaging portion 722 is in contact with one end portion of the coil spring 726 and is always Is biased upward. The spring 726 can be replaced with an equivalent material such as a leaf spring or a piano wire instead of a coil spring.

And the pin position control part 750 is comprised from the support part 752 formed in the predetermined position of the pin storage space 751 of the main body side sealing part, and the engaging part 753 formed in the predetermined position of the sealing pin 700C. ing. Here, the following structure is used.
That is, the length L1 from the base end portion 723 of the sealing pin 700C of the engaging portion 7530 formed at a predetermined position of the sealing pin 700C is set shorter than the length L2 from the distal end engaging portion 722. Accordingly, the position of the support portion 752 formed at a predetermined position of the pin storage space 751 is also set such that the distance L3 from the bottom portion to the support portion 752 is longer than the length L2 from the front end engaging portion 722 of the sealing pin 700C. Slightly longer, the distance L4 from the upper opening to the holding portion 752 is slightly longer than the length L1 from the base end portion 723, so that the sealing pin 700C has a downward posture, as shown in FIG. When it is inserted into the pin storage space 410 in the preliminary storage posture, it is completely buried (preliminary storage posture). However, as shown in FIG. Projecting from the scan 7530, the exposed state (sealing position).

(Modification 2 of a sealing member having a special structure)
Further, in order to make the special sealing member used for the initial sealing different from other multiple-use sealing members, unlike the resin-molded sealing member 700 and the machine element sealing member 700C of the previous embodiment. Here, a special metal tube (tubular member) is employed to prevent unauthorized persons from imitating more easily. Of course, for the other plurality of sealing portions and sealing members, the structure of the sealing sealing portion and the sealing members (first sealing fitting 700A and second sealing fitting 700B) of the above-described embodiment are used. Yes.
The sealing member 700D will be described with reference to FIG.

  As shown in FIGS. 34 (A) to (C), the second case side sealing portion 501 at the right end here has a substantially bottomed rectangular tube shape with the side corresponding to the bottom surface side of the first case portion opened. The insertion hole 503 for inserting the sealing member 700D is formed in the bottom corresponding to the opening side of the first case 400. Notches are provided on both sides of the insertion hole 503 to reduce weight and reduce material costs. Further, the first case side sealing portion 401 is formed with a pair of tongue pieces 404 and 404 by providing notches in a pair of opposing side walls. On the inner surface side of each tongue piece 404, a holding portion 405 for temporarily fastening the sealing member 700D is provided. The holding portion 405 includes claw portions 405A and 405A having a tapered cross section tapered toward the center of the holding portion 405, which are arranged in tandem on the inner surface side of each tongue piece 404. In the present embodiment, the first case side sealing portions 401 are connected to each other by the first ribs, and are formed integrally with the outer wall of the first case portion 400 by the second ribs 7. Each rib is easily broken by applying a desired external force.

  The second case-side sealing portion 501 has a hollow, substantially rectangular parallelepiped shape, and the sealing member 700D is inserted into the opening-side surface of the second case portion (the surface facing the bottom of the first case-side sealing portion 401). It is set as the structure which formed the penetration hole 503 for letting it pass. Moreover, in this embodiment, the 1st case side sealing part 401 is mutually connected with the rib.

  The sealing member 700D is a tubular member made of a soft metal material (for example, aluminum or copper) excellent in malleability. As shown in FIGS. 34A to 34C, the sealing member 700 </ b> D is inserted into the insertion hole 403, 503 and the flange 711 to be locked to the first case side sealing portion 401 in order from the base end side. It has a cylindrical tubular portion 702 that passes therethrough, and has a screwing portion 713 for screwing a screw 800 inserted from the base end side of the sealing member 700D. The flange 711 has a substantially rectangular shape corresponding to the inner shape of the first case side sealing portion 401. That is, the inner peripheral portion of the first case side sealing portion 401 is an engaging portion 408 that engages the flange 711 of the sealing member 700D so as not to be relatively rotatable. The cylindrical part 702 has substantially the same diameter as the insertion hole 503 of the second case side sealing part 501. The length of the cylindrical part 712 is such that a part (tip part) of the cylindrical part 712 is in the second case in a state where the front surface side of the flange 711 is in contact with the bottom wall surface of the first case side sealing part 401. The length projects from the insertion hole 503 of the side sealing portion 501. Both the inner and outer diameters of the threaded portion 713 are formed smaller than the inner and outer diameters of the cylindrical portion 712. Further, the thickness of the sealing member 700D is substantially the same for both the cylindrical portion 712 and the screwing portion 713. The length of the sealing member 700 </ b> D is such that the front end of the screwing portion 713 is the first case side sealing portion 401 in a state where the flange 711 is temporarily fixed to the holding portion 405 of the first case side sealing portion 401. The length does not reach the insertion hole 403. This is to allow relative movement of the second case portion 500 and the first case portion 400 in a state where the sealing member 700D is temporarily fixed to the holding portion 405.

A sealing process of the substrate case 263 by the special sealing member 700D will be described.
FIG. 34A shows a state where the sealing member 700 </ b> D is temporarily fixed to the holding portion 405 of the first case side sealing portion 401. When the sealing member 700D is pushed in along the inclination of the claw portions 405A and 405A from this state, the tongue pieces 404 and 404 are gradually expanded so that the sealing member 700D is located behind the first case side sealing portion 401. Pushed in. Since the inner peripheral shape of the first case side sealing portion 401 is formed to correspond to the contour shape of the flange 711 of the sealing member 700D, the sealing member 700D is the inner peripheral surface of the first case side sealing portion 401. The cylindrical portion 712 is inserted into the insertion holes 403 and 503 of the first case side sealing portion 401 and the second case side sealing portion 501.

  FIG. 34B shows a state in which the sealing member 700D is pushed into the first case side sealing portion 401 and inserted into the insertion hole 403 and the insertion hole 503 of the second case side sealing portion 501. Yes. In the state of FIG. 5B, a screw 800 as a part of the axial force generating means is inserted from the proximal end side of the sealing member 700D. The outer diameter of the screw 800 is slightly larger than the inner diameter of the screwing portion 713. For this reason, just inserting the screw 800 into the sealing member 700D as shown in FIG. 4B, the tip of the screw 800 is only carried on the step formed at the inner peripheral upper end position of the screwing portion 713. It becomes the state of.

  FIG. 34C shows a state in which the screw 800 is screwed into the screwing portion 713 of the sealing member 700D from the state of FIG. In this embodiment, as shown in FIGS. 4A and 4B, the inner surface of the screwing portion 713 is not threaded in advance. That is, as shown in FIG. 5B, when the screw 800 having an outer diameter larger than the inner diameter of the screwing portion 713 is screwed, the screw 800 is screwed while the inner surface of the screwing portion 703 is threaded.

  FIG. 34C shows a state in which the screw 800 is further screwed and tightened from the state of FIG. When the screw 800 is tightened in a state where the screw head 801 (the flange portion) is in contact with the flange 711, the screw 800 is rotated in a state in which the axial movement of the screw 800 is prevented. A large axial compressive force is applied to the cylindrical portion 712 of the stop member 700D, and the cylindrical portion 712 of the sealing member 700D is buckled by plastic deformation in the diameter-enlarging direction, and caulking is performed. That is, the cylindrical portion 712 of the sealing member 700 </ b> D has a larger diameter than the threaded portion 713, and thus the axial rigidity is smaller than that of the threaded portion 713. For this reason, when the screwing portion 713 is pulled toward the proximal end side by tightening the screw 800, the cylindrical portion 712 is compressed and the portion protruding from the insertion hole 503 of the second case side sealing portion 501 undergoes plastic deformation. A locking portion 714 is formed to increase the diameter and lock the second main case side sealing portion 501. After the locking portion 714 is formed, the screw 800 may be either attached to the sealing member 700D or removed, but is usually removed. If the screw 800 is left attached, when the substrate case 263 is unsealed by inspection or the like and sealed again with another sealing portion, if it is removed and used, it is necessary to prepare another screw. It is convenient. Further, there is an advantage that the rigidity of the sealing member 700 against the shearing force is increased. The screw 800 is removed from the sealing member 700 after the locking portion 704 is formed.

In this way, for one of the first sealing member and the second sealing member, a sealing member 700D suitable for the first sealing member and the second sealing member is used. Even if the first case and the second case are forged by being different from the second sealing member, the initial sealing member of the unique structure cannot be easily obtained, so the initial sealing is not released. You can't camouflag the state.
Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.
For example, when at least one pair is used for initial sealing among a plurality of first sealing members and second sealing members, and when two pairs are used for initial sealing, one or two are others. The first sealing member used for the second sealing, the second sealing member, and the first sealing member used after the third position and The structures of the second sealing member and the sealing member may be different from those of the first, second and other counts.
In short, if the built-in sealing member other than the first sealing that can be obtained by being discarded or destroyed cannot be substituted for the case of the newly counterfeited substrate unit, the present invention. These objectives are achieved, and various combinations for such purposes are the subject of the present invention.

  The present invention prevents fraudulent impersonation that makes it difficult to discern fraud of ROM exchange based on counterfeit molding of a board unit, and various games such as pachinko machines, slot machines, game machines, etc. that employ it. It can be applied to the machine and its availability is great.
