Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine such as a slot machine or a pachinko machine, and in particular, a game control means for controlling the progress of a game on the gaming machine, a production means for performing an effect relating to the progress of the game, etc. The present invention relates to a gaming machine mounted on a main body in a state where a control board provided with a predetermined control means such as a production control means for controlling the is housed in a housing case.

[0002]

2. Description of the Related Art Conventionally, a slot machine as an example of this type of game machine has a game control board provided with game control means (CPU, ROM, etc.) for controlling the progress of the game, and the progress of the game. A control board provided with a predetermined control means, such as an effect control board provided with an effect control means for controlling an effect means for effecting an effect.

In recent years, there have been many fraudulent acts in which an unreasonable profit is gained by improperly processing the control board or replacing it with improperly modified control means. In order to suppress such illegal acts on the control board, the control board is attached to the housing in a state of being covered with the housing case.

On the other hand, since such a storage case may be opened when the control board is stored or when the shop side inspects the control board, it has been necessary to make it openable.

In order to meet these requirements, the control board is housed in a housing case that is composed of a case body that houses the control board and a case cover that covers the housing case body, and a predetermined portion of the housing case. Unless you destroy
In order to prevent the case cover from being opened or removed from the slot machine main body, it is difficult to rotate, for example, in the removal direction with respect to an attachment member previously attached to a predetermined location of the slot machine main body. It is known that a one-way screw or the like is used to leave a trace when the screw is attached and released or removed.

Particularly, in such a housing case, a plurality of mounting portions for mounting the housing case in an unopenable manner and non-removable with respect to the mounting member are provided outward from the case body and the case cover, respectively. Since it is formed on each protruding sealing piece, if it is necessary to open or remove it after mounting it on the main body as described above, it is sufficient to break the sealing piece fixed by the one-way screw or the like. Also, the next fixing could be attached to the main body by using another sealing piece.

[0007]

However, when the housing case is opened and removed a plurality of times, it is sufficient to break the sealing piece for each of the housing cases as described above, and finally a new one is created. However, in order to reuse (recycle) the main body of the slot machine, the broken sealing piece on the mounting member previously attached to the main body of the slot machine is fixed by the one-way screw or the like. In the case where it remains in the state of being kept, the mounting member had to be removed from the main body and a new mounting member had to be fixed to the main body with screws or the like.

In this case, if the mounting member, which has to be permanently attached to the main body of the slot machine in advance, is frequently replaced with the repeated opening and removal of the housing case, for example, in the main body of the slot machine. There is a possibility that the fixing strength of the screw for mounting the mounting member is reduced due to the widening of the screw-in hole of the screw, and thus the mounting strength of the housing case is reduced.

In order to solve such a problem, the mounting portion of the one-way screw in the mounting member is formed separately from the mounting member, as described in, for example, Japanese Patent Laid-Open No. 2000-354673. For example, there is a fixing member formed so that the fixing member can be detached from the mounting member when the housing case is removed.

However, in this case, since it is necessary to mold the fixing member separately from the mounting member, there is a problem that the number of parts is increased and the structure is complicated, resulting in an increase in manufacturing cost.

The present invention has been made by paying attention to such problems, and when the storage case is detached from the main body of the gaming machine, it is attached so that the traces remain, and the storage case is opened or removed. It is an object of the present invention to provide a gaming machine in which the mounting strength of the mounting member for mounting the housing case does not decrease even when the number of times is high.

[0012]

In order to solve the above problems, a gaming machine of the present invention is a gaming machine in which a player can play a predetermined game, and the gaming machine has a predetermined control means. It is provided with a housing case for housing the control board provided, and the housing case can be released from its mounting state unless a predetermined portion is destroyed by a mounting member provided in the main body of the gaming machine. It is attached by attaching means so that it does not exist, and the main body of the gaming machine is pre-fixed with holding means for holding the attaching member in the state of being attached to the main body of the gaming machine. Is characterized in that the holding state of the attachment member can be released in a state where the housing case is removed, and the attachment member can be removed. According to this feature, since the control board is housed in the housing case, it is hard to be tampered with and
When the housing case that is non-removably attached to the main body of the gaming machine via the mounting means is removed from the main body of the gaming machine, for example, at least a part of the housing case is destroyed, so that traces are surely left. Therefore, it is possible to immediately detect from outside that there is a possibility that fraud has been committed, so fraud can be effectively suppressed. Further, since the mounting member can be easily removed from the main body of the gaming machine with the housing case removed, a new mounting member can be used when a trace of the housing case remains on the mounting member when the housing case is removed. Can be exchanged for
Since the holding means is not attached to or detached from the main body of the gaming machine when attaching or removing the attaching member, the attaching strength of the holding means to the main body of the gaming machine does not decrease, and the attaching strength of the housing case decreases. Can be effectively avoided, and the main body of the game machine can be reused. Further, since the number of parts is small, the structure does not become complicated and the cost does not increase. The housing case includes a case body that houses the control board therein, and a case cover that is attached to the case body so as to cover the control board housed in the case body. It is preferable that the main body and the case cover are fixed so as not to be opened by a fixing means so that the covering state cannot be released unless a predetermined portion is broken. In this way, when the storage case is opened, for example, at least a part of the storage case is destroyed, so that traces are surely left,
Since it is possible to immediately discover from outside that there has been a possibility of fraud, fraud can be effectively suppressed.

It is preferable that the mounting member of the gaming machine of the present invention is mounted on the main body of the gaming machine via the holding means at a position where the mounting member is covered by the housing case and cannot be touched from the outside. . If you do this,
Since the holding means cannot be easily touched when the housing case is attached, removal of the housing case by removing the holding means is reliably prevented.

In the gaming machine of the present invention, the mounting member is composed of a plurality of members, and among the plurality of members, a member that can leave a trace of removal of the housing case is in a state where the housing case is removed. It is preferably held by the holding means so that it can be removed from the main body of the gaming machine. By doing so, it is economical because only the member having the trace of the housing case remains replaced, and it is not necessary to replace other members that do not need to be replaced.

In the gaming machine of the present invention, the attachment member is composed of a plurality of members, and one of the plurality of members is attached with a seal sticker to which one end of the seal sticker attached to the housing case is attached. It is preferable that the member formed with is held by the holding means so that it can be removed from the main body of the gaming machine in a state where the housing case is removed. By doing so, only the member in which a part of the seal is left unnecessarily replaced, and other members that do not need to be replaced need not be replaced, which is economical.

The holding means of the gaming machine of the present invention comprises a shaft member having one end fixed to the main body of the gaming machine and a holding portion formed at the other end, and the mounting member includes the shaft member. A hole formed of an insertion hole formed so as to be able to pass through the holding portion and an elongated hole formed so as not to be able to pass through the holding portion that is connected to the insertion hole, and the mounting member is formed. ,
It is preferable that the holder is held by the shaft member by the holder while the holder is inserted through the insertion hole and then slid to position the shaft member in the elongated hole. By doing this, by sliding the mounting member with the shaft member inserted in the hole,
Since the mounting member can be held in the shaft member or released from the held state, the mounting member can be easily attached to and removed from the shaft member.

Further, the gaming machine of the present invention is a gaming machine in which a player can play a predetermined game.
It is provided with a control board provided with a predetermined control means, and the control board cannot be released from its attached state unless a predetermined portion is destroyed by an attachment member provided on the main body of the gaming machine. As described above, the holding means for holding the mounting member attached to the main body of the gaming machine is fixed to the main body of the gaming machine in advance. It is preferable that the holding state of the attachment member can be released when the control board is removed, and the attachment member can be removed.

Further, in the gaming machine, the game can be started by setting the bet number for one game, and the display result of the variable display device capable of changing the display state is derived and displayed. As a result, one game is completed, and it is preferable that the slot machine is capable of generating a predetermined winning according to the display result of the variable display device.

02, the reel control signal is output via the motor circuit 216. This reel control signal is sent to each reel 51L, 51C, 51R via the reel relay board 203.
It is input to separately provided reel motors 54L, 54C, 54R. Further, the reel control signal is output to the outside of the slot machine 1 via the reel relay board 203 and the external output board 205.

As a result, each reel 51L, 51C, 5
1R begins to fluctuate. In addition, the reel control signal transmission path is the reel motor 54 in the reel relay board 203.
The reel control signal is branched to the L, 54C, 54R side and the external output board 205 side, and the reel control signal output to the external output board 205 side is output from the external output board 205 to the slot machine 1.
Is also output to outside. In this way, the external output board 20
The reel control signal output from 5 is not a signal processed for external output, but reel motors 54L, 54C, 5
It is the signal itself for controlling the drive of the 4R.

Further, in response to the detection signal of the start switch 102 being input, the control section 210 outputs a command capable of specifying the start of the game to the effect control board 201 via the buffer circuit 220. Production control board 2
The control unit 230 of 01 grasps the game situation based on the command, and according to the effect pattern determined corresponding to the start of the game, each of the game effect lamps 130 to 134, the liquid crystal display 135, the speakers 136a, 137b, 137, etc. To control.

Further, each stop switch 103L, 10L
The stop switch signals output from 3C and 103R are transmitted through a signal path that reciprocates between the game control board 200, the reel relay board 203, and the external output board 205, and then input to the switch circuit 215 of the game control board 200. . Furthermore, the stop switches 103L, 103C,
The stop switch signal output from 103R is directly
It is configured to be output to the outside via the external output board 205.

Upon receiving the stop switch signal input, the control section 210 receives reel motors 54L, 54C, 54R corresponding to the stop switch signal via the motor circuit 216.
And outputs a reel control signal for stopping. This reel control signal is supplied to the reel motors 54L, 54C, 54R.
And is output to the outside of the slot machine 1 via the external output board 205.

Further, the control unit 210 responds to the input of the stop switch signal by the buffer circuit 22.
A command capable of specifying the reel stop time is output to each reel 51L, 51C, 51R via 0 via the control board 201. The control unit 230 of the effect control board 201 follows the effect pattern determined corresponding to the reel stop time based on the command, and the game effect lamps 130 to 1
34, liquid crystal display 135, speakers 136a, 13
6b, 137, etc. are controlled.

The signal output from the external output board 205 can be used, for example, when a third party organization conducts a type test. In this type test, for example, it is confirmed whether or not each reel 51L, 51C, 51R corresponding to each stop button 40L, 40C, 40R is stopped within 190 ms after the operation of each stop button 40L, 40C, 40R. In the case of this slot machine 1, since the stop switch signals output from the stop switches 103L, 103C, 103R are directly output from the external output board 205, the stop buttons 40L, 40C, 4
The timing when the 0R is operated can be accurately grasped outside the slot machine. Similarly, since the reel control signal output from the motor circuit 216 is directly output from the external output board 205, the start and stop timings of the reels 51L, 51C and 51R can be accurately grasped outside the slot machine. Therefore, by using the signal output from the external output board 205, “each stop button 40L, 4L
Each reel 51 corresponding to each stop button 40L, 40C, 40R within 190 ms from the operation of 0C, 40R
An accurate test result can be obtained when the "test for whether L, 51C, 51R stops" is performed. In addition, “a configuration in which the control unit 210 of the game control board 200 once receives the signal and then outputs the signal to the external output board 205”
In such a case, there is a possibility that a fraud such as processing and outputting a signal is made on the game control board 200 side, but according to the present embodiment, such fraud can also be prevented.

In the slot machine 1 of the present embodiment, when the variable display device 50 is stopped, any of the pay lines L1, L2, L activated according to the number of bets.
2 ', L3, L3', for example, "BAR-BAR-BA
If the symbols of "R" are aligned, it means that you have won the RB (Regular Bonus) which is a big hit, and "BAR-BAR-
For example, 15 medals are paid out as a consideration that the symbols of “BAR” are arranged, and an RB (regular bonus) which is a special game state advantageous to the player occurs, and the regular bonus game described below is played. It is given to the player as a value. In this RB,
Jac games in which a predetermined number of medals are paid out by aligning the Jac symbols (plums in the embodiment) with a high probability are provided 12 times at the maximum, and this Jac game is also performed 12 times. The game ends when either the condition is satisfied, or the Jac prize is generated 8 times before the Jac game reaches 12 times. Therefore, the player can get a maximum of eight Jac winning opportunities during the 12 Jac games.

On the other hand, the activated pay lines L1 and L
2, L2 ', L3, L3', for example, "black 7-black 7-
If you have "Black 7" or "White 7-White 7-White 7", you have won the BB (Big Bonus).
For example, 15 medals are paid out as a consideration for having the symbols of "black 7-black 7-black 7" or "white 7-white 7-white 7", and in a special game state advantageous to the player. A certain BB (big bonus) occurs, and a small winning game described below is given to the player as a game value. To be more specific, in this BB, a small winning combination with a high probability that small winning symbols (bells, plums in the embodiment) are aligned with a high probability and a predetermined number of medals are paid out is generated with a high probability. If the winning combination game is provided up to 30 times and the Jac symbols are aligned until the small winning combination game is executed 30 times and the JacIn prize is won, the special game state RB occurs. The regular bonus game is provided. This RB
Has a predetermined maximum number of occurrences in BB, and in the present embodiment, it can occur up to three times. This BB is executed when 30 small win games are executed and ended, or when three RBs are provided before the small win game is executed 30 times and the third RB is ended. , And ends when at least one of the conditions is satisfied.

Further, in the case of a normal game state (base game) other than the special game state, when a predetermined prize is established in line on one activated line in which symbols of the same kind are activated, , A predetermined number of medals predetermined according to the type of the symbol are given to the player. The "cherry" drawn on each reel 51L, 51C, 51R
The symbol is a mark called a single symbol, and when this single symbol is stopped and displayed on one effective line, it is 2
The number of medals is given to the player. If there are multiple activated lines activated according to the number of bets, and if the combination of symbols for which medals are paid out is simultaneously established on multiple winning lines as described above, each winning line is As a general rule, medals corresponding to the total number of medals given by the combination of symbols on the line are given. However, since the maximum number of medals given to a player in one game is set at 15,
If the number of medals exceeds 15, the 16th and subsequent medals are invalidated.

In this embodiment, black 7-black 7-black 7 (black 7 award), white 7-white 7-white 7 in the normal game state.
(White 7 Award), BAR-BAR-BAR (BAR Award), Watermelon-Watermelon-Watermelon (Watermelon Award), Cherry (Cherry Award), Bell-Bell-Bell (Bell Award), or Plum-
Plum-Plum (replay) is the target of the prize, and only the black 7 or white 7 pattern and the BAR pattern are the jackpots (BB, RB), which are the most profitable prizes for the player. Other special cherries, bells or plums (replays) are considered to be small symbols, which are small prizes for the player.

The combination of the symbols targeted for each prize and the number of payout medals corresponding to the combination of the symbols (including the probability of winning) are corresponding to the normal game, BB, and RB. These are predetermined respectively, and these are stored in the ROM 2 as the winning determination table described above.
It is registered in 13.

A male screw portion 5 screwed into the female screw hole 533a of the embedded nut 533 is provided on the outer periphery of the head 535b on the opposite side.
35d is formed. Specifically, the shaft portion 535a is formed so that the elongated hole 521b formed in the base member 517 can be inserted therethrough, and the head portion 535b cannot be inserted through the elongated hole 521b of the base member 517, and serves as an insertion hole. The large-diameter hole portion 521a is formed to have a size that can be inserted therethrough. Further, the flange portion 53 of the shaft portion 535a
A male screw portion 535d that is screwed into the female screw hole 533a of the embedded nut 533 is formed on the outer periphery of the head portion 535b opposite to the center of 5c.

The locking pin 535 thus formed is
As shown in FIG. 10B, at the stage before the base member 517 is attached to the back plate 85, the male screw portion 5 of the base member 517 is attached.
The flange portion 535 is provided in the female screw portion 533a of the embedded nut 533 in which 35d is embedded in the back plate 85 so as not to deviate.
The c is screwed in until it is housed in the housing portion 534, and is attached to the back plate 85 in advance so that it cannot be deviated. That is, the locking pin 535 as a holding means is fixed to the back plate 85.

In this embodiment, the locking pin 535 as the holding means is constructed so that it can be attached to the embedded nut 533 of the back plate 85, but such a locking pin 535 is embedded. It may be formed integrally with the lock nut 533 in advance, or the locking pin 535 may be formed integrally with the back plate 85 in advance.

Then, as shown in FIG.
The upper and lower locking pins 535 fixed to the back plate 85 as described above are provided with two large-diameter hole portions 521a of the base member 517.
And the bottom surface of the base member 517 is brought into contact with the front surface of the back plate 85. In this state, the head portion 535b of the locking pin 535 is in a state of protruding to the upper surface side of the bottom plate 519 (see FIG. 10C).

From this state, as shown in FIG.
By sliding the base member 517 toward the opposite direction of the base member 518, the shaft portion 535a of the locking pin 535 is positioned in the elongated hole 521b, and the base member 5
Since the bottom surface of the head portion 535b abuts around the elongated hole 521b on the upper surface of the bottom plate 519 of No. 17, the base member 517
Is held by the locking pin 535 so as not to deviate from the front surface of the back plate 85. That is, the base member 517 is held in a predetermined position on the front surface of the back plate 85.

Thus, as shown in FIGS. 6 and 11, the accommodating case 500 is attached to the base member 517 and the base member 518, which are attached to the upper portion of the front surface of the back plate 85 so as to be separated from each other by a predetermined distance. It will be able to be attached to.

The housing case 5 is attached to the base members 517 and 518.
In the case of attaching 00, the housing case 500 is slid from the state shown by the chain double-dashed line in FIG. 12 in the direction of arrow Y in the figure. Then, the end of the housing case 500 on the side of the locking piece 505 is attached to the restriction piece 531 of the base member 518.
The bottom surface of the bottom plate 502a of the lower case 502 with the base member 517,
The housing case 500 is placed on the base members 517 and 518 so as to abut the upper end surfaces of the support pieces 526 and 520 of the 518.

In this state, as shown in FIG. 12 and FIG. 13, the lower surfaces of the four inner sealing pieces 516 are brought into contact with the upper surfaces of the raised portions 523, and the two sealing pieces 516 on both ends are provided. The lower surface of the'is brought into contact with the upper surfaces of the step portions 522 at both ends thereof, and the base member 51 on one end side of the housing case 500 is
The deviation from 8 is prevented by the restriction piece 531 and the side end surface of the restriction piece 531 and the side end surface of the raised portion 512 formed on the upper case 501 face each other.

Here, it is held in any one of the four sealing pieces 511 other than the both ends (in FIG. 13, the sealing piece 511 on the right side of the sealing piece 511 'on the left end side). If you screw in the one-way screw 509
The screw portion of 09 is screwed into the hole portion 515 of the sealing piece 516 and the hole portion 524 of the base member 517 by a thread cutting action, so that the upper case 501 and the lower case 502 are fixed so as not to be opened by the one-way screw 509. In addition, the housing case 500 including the upper case 501 and the lower case 502 that are fixed so as not to be opened is provided with the base member 51.
7, 518 attached.

Here, as shown in FIG. 11, the sliding movement of the base member 517 held by the locking pin 535 toward the base member 518 causes the base member 518 fixed to the back plate 85 to move. Since the base member 517 is reliably prevented from deviating from the locking pin 535 by being regulated by the housing case 500 whose ends are held, the housing case 500 includes the base members 517, 51.
It will be fixed irremovably to the back plate 85 via 8.

In this state, the base member 51
Locking pin 535 for holding 7 to the back plate 85 and fixing screw 527 for attaching the base member 518 to the back plate 85.
The upper part of the base members 517 and 518 is covered with the housing case 500 that is fixed to the base members 517 and 518 in a non-removable manner, and the locking pins 535 and the fixing screws 527 cannot be touched from the outside. It is difficult to remove it easily.

In this state, when the containing case 500 is to be opened, or when the containing case 500 is used as the base member 51.
7 and 518, it is difficult to remove the screwed one-way screws 509, and the sealing pieces 511, 511 ′ and the sealing pieces 511 and 511 ′ as the predetermined parts into which the one-way screws 509 are screwed are difficult to remove. 516,516 '
Since it is difficult to open or remove it unless it destroys a predetermined part, such as cutting and disconnecting etc.,
Not only can fraudulent acts such as replacing the ROM 213 mounted on the game control board 200 effectively suppressed,
Even if it is removed, the sealing pieces 511, 51
1'and the sealing pieces 516, 516 ', etc. will be destroyed by being cut off, etc., so the traces will surely remain, so it is possible to easily judge from the appearance that fraudulent acts may have been performed. Can be done. In addition, needless to say, the predetermined portion is the sealing piece 511 in the housing case 500,
511 ′ and sealing pieces 516, 516 ′ are not limited to the sealing pieces 511, 5 in the housing case 500.
11 'and the sealing pieces 516, 516', and the base member 517, the back plate 85, and the like, and all the parts from which the housing case 500 can be removed by breaking.

More specifically, the upper case 501 and the lower case 502 are one-way screws 50 as fixing means.
In the state where the one-way screw 509, which is the fixing means, cannot be removed in the state where the one-way screw 509 is fixed so as not to be opened by 9 and cannot be opened unless a predetermined part of the housing case 500 is broken. Further, when the housing case 500 is irremovably attached to the base member 517 by the one-way screw 509 serving as the mounting means, the one-way screw 509 serving as the mounting means cannot be removed, and a predetermined portion of the housing case 500 is destroyed. Unless it is done, it cannot be removed from the base member 517.

Further, since the housing case 500 cannot be detached from the back plate 85 only by fixing one end side of the housing case 500 with the one-way screw 509 so as not to be opened, the one-way screw 509 can fix a plurality of places. Without this, the housing case 500 can be attached by a simple operation.

In addition, the upper case 50 of the housing case 500
1 and the lower case 502 are fixed to each other in a non-openable state, and a base member 51 fixed to the housing 2a.
Since the mounting means for irremovably mounting the housing case 500 to the No. 7 is composed of the same one-way screw 509, the housing case 500 can be easily closed and mounted to the back plate 85. Not only can
The housing case 500 is a back plate 8 using one-way screws 509.
The workability is improved because it is fixed so that it cannot be opened when it is attached to the device.

Also, the housing case 500 has sealing pieces 511, 511 'and sealing pieces 516, 516' for fixing the upper case 501 and the lower case 502 with the one-way screw 509 so that they cannot be opened. Since a plurality of the sealing pieces 5 are provided in each case, even when the housing case 500 is opened or detached from the back plate 85 due to some factor such as an inspection, the sealing piece 5 is not broken during opening or detaching.
By using 11, 511 ′ and the sealing pieces 516, 516 ′, the housing case 500 can be fixed again so that it cannot be opened and cannot be removed from the back plate 85.

Further, since these sealing pieces 511, 511 'and sealing pieces 516, 516' are formed so as to project from the side of the upper case 501 and the lower case 502, they need to be removed and opened. In this case, since the sealing pieces 511, 511 'and the sealing pieces 516, 516' can be removed and opened without destroying an important part that covers the game control board 200, the housing case 5
00 can be used repeatedly.

Further, as described above, a fixing means for fixing the upper case 501 and the lower case 502 in a non-openable manner, and a mounting means for mounting the housing case 500 composed of these cases to the base members 517, 518 are provided. In particular, the present invention is not limited to the one-way screw 509 as described above, but can be variously modified. For example, even if a conventionally known blind rivet or the like (not shown) is used, the same action and effect as the case where the one-way screw 509 is used are obtained. Can be obtained.

Further, in the present embodiment, the upper case 501 and the lower case 502 which form the housing case 500.
One one-way screw 509 is used as a fixing means for fixing and to prevent the opening and a fixing means for fixing the housing case 500, which is a case, to the back plate 85 via the base members 517 and 518. Although it has been used in common, the present invention is not limited to this, and the fixing means and the attaching means may be configured separately. Specifically, a one-way screw for fixing the upper case 501 and the lower case 502 to each other in a non-releasing manner, and a one-way way to attach the housing case 500 including the upper case 501 and the lower case 502 to the back plate 85 in a non-removable manner. The screws may be separate one-way screws.

Then, as described above, the base members 517, 51
In the state where the housing case 500 is attached to 8,
As shown in FIG. 12, the upper surface 512 a of the raised portion 512.
And the upper surface 531a of the restriction piece 531 of the base member 518 are substantially flush with each other, so that the housing case 500 and the base member 5 are
The sealing seal 536 that is adhered over 18 is easily peeled off because a gap or the like is formed from the upper surface 512a of the raised portion 512 to the upper surface 531a of the restricting piece 531 and the upper end of the outer surface of the side plate 530b of the base member 518. It can be attached so that it does not come off and it looks good.

After the housing case 500 is attached to the back plate 85, if the housing case 500 is opened or detached from the base members 517 and 518, as described above, a sealing is performed at the time of opening or detaching. Stops 511, 51
1 ', 516, 516', etc. are broken, and the broken sealing pieces 511, 511 ', 516, 516' are inserted into the holes 524 of the base member 517 through the one-way screws. It remains in the state of being attached to the base member 517 side together with 509.

Therefore, the sealing piece 511 can be opened or removed.
The number of times corresponding to the number of attachments of 511 '(4 in this embodiment)
More than once) or a new storage case 5
For example, when the housing case 500 is attached, the sealing piece 51 left on the base member 517 is replaced.
1, 511 ', 516, 516' and one-way screw 50
9 is an obstacle, it is necessary to replace the base member 517. However, the base member 517 in this embodiment is the base member 518 with the housing case 500 removed.
The large-diameter hole portion 521 can be slid toward the side.
Since the head portion 535b of the locking pin 535 can be aligned with the position of a, it becomes possible to deviate from the locking pin 535, and the holding state by the locking pin 535 is released. New base member 517
It can be easily replaced.

When replacing the base member 517, it is not necessary to remove the locking pin 535 as a holding means for holding the base member 517 from the back plate 85.
Even if the number of times of exchanging the base member 517 increases, the locking pin 535 is fixed to the back plate 85 due to, for example, wear of the male screw portion 535d of the locking pin 535 and the female screw portion of the female screw hole 533a of the embedded nut 533. The reduction in strength does not reduce the attachment strength of the accommodation case 500 to the back plate 85, so that it is possible to effectively prevent illicit acts such as replacement of the accommodation case 500.

Needless to say, the embedded nut 533 integrated with the locking pin 535 as the holding means is replaced with the back plate 85 of the housing 2a constituting the main body of the slot machine 1 when the base member 517 is replaced. Since it is not necessary to remove the embedded nut 533 from the back plate 85, the embedded nut 533 is removed from the back plate 85 every time the base member 517 is replaced, and the embedded hole of the embedded nut 533 in the back plate 85 is widened. Since the fixing strength to 85 is not reduced, the attachment strength of the housing case 500 to the back plate 85 is not reduced, and the back plate 85 and the back plate 85 are not reduced.
It is possible to reuse the housing 2a including the same without replacing it.

Also, the base member 517 in this embodiment.
Is attached to the back case 85 by attaching the housing case 500.
Since it is irremovably attached to the back plate 85, it is not necessary to irremovably attach to the back plate 85 before the accommodation case 500 is attached. Therefore, workability is improved.

Further, the mounting member for mounting the housing case 500 to the back plate 85 is composed of a plurality of members (two base members 517 and 518 in this embodiment), and among the plurality of members, the housing case. Only the mounting portion (member having the hole 524 (base member 517) of 500 is replaceably mounted via the locking pin 535 which is the holding means as described above. Part of which can remain (base member 517)
It is economical because only the other member (base member 518) that need not be replaced does not have to be replaced.

Furthermore, a locking pin 535 as a holding means
The locking state in which the locking (holding) state can be released by being continuously provided near the periphery of the elongated hole 521b in the bottom plate 519, which is the locked portion (holding part) locked (held) by the head portion 535b. Since the large-diameter hole portion 521a, which is the release portion, is formed in the base member 517, which is the replaceable attachment member, a reduction in holding force is effectively prevented, and the base member 51
Since the state in which the base member 517 is held by the locking pin 535 or the state in which it is held can be released only by sliding the base member 517, it is easy to attach and detach the base member 517 to and from the locking pin 535. Can be done.

As described above, in this embodiment, the hole portion 524 as the mounting portion for mounting the housing case 500.

It may be made possible to replace the housing case 500 via the 35 'in a state where the housing case 500 is removed.

This is because the base member 518 is formed with the restriction piece 531 which serves as a seal sticker adhering portion to which the above-mentioned seal sticker 536 is stuck, so that the seal piece is broken by repeated opening or removal, for example. Seal 53
This is because the debris of No. 6 may remain on the upper surface of the upper surface 531a of the restriction piece 531 and the seal 536 may be replaced in order to attach it so as not to be easily peeled off.

Here, the hole portion 524 as the mounting portion of the housing case 500 and the restriction piece 531 serving as the sticking portion to which one end of the seal sticker 536 stuck to the housing case 500 is stuck respectively. Separate member (base member 51
7, 518), but when the mounting member is composed of a plurality of members in this way, the mounting portion (hole 524) and the sticking portion (regulating piece 531) are the same member. (For example, one of the base member 517 and the base member 518) may be formed. In this case, if only the member on which these are formed is provided so as to be replaceable via the holding means, it is economical because other members that do not need to be replaced need not be replaced.

Further, as described above, both base members 517, 5
In the case where 18 is made replaceable, in FIG. 14, the large-diameter hole portions 521a and 521a ′ are mutually attached so that the housing case 500 is attached in a state in which both base members 517 and 518 are moved in a direction in which they are separated from each other. The holes 521 and 521 'are formed so as to be located on the outer side, but the large diameter holes 521 and 521' are formed so that the housing case 500 can be attached in a state in which the base members 517 and 518 are moved in the direction in which they approach each other. Parts 521a and 521
The holes 521, 52 are arranged so that a'is located inside each other.
1'may be formed.

Further, the mounting member in this embodiment can be attached to the left and right longitudinal ends of the housing case 500.
Although it is composed of one base member 517, 518, the housing case 500 may be attached by two or more base members, or
It may be composed of one member.

That is, if the housing case 500 is attached in a state where the housing case 500 is moved in the opposite direction, the housing case 500 and the base member 51 are integrated with each other.
7, 5, 518 are slid in either the left or right direction, so that both locking pins 535, 535 ′ are moved to the base member 51.
7,518 are prevented from deviating simultaneously.

Next, FIGS. 15 to 17 show modified examples of holding means for holding the mounting member in the housing 2a which is the main body of the slot machine 1. As shown in FIG.

In the holding means shown in FIG. 15, a male screw portion is formed on the outer circumference, and a metallic screw member 537 is provided upright from the back plate 85 toward the front side, and a tip end of the screw member 537. It is composed of a metal nut 538 which can be screwed. One end of the screw member 537 is fixed to the back plate 85 by being screwed into the female screw hole 540a of the embedded nut 540 embedded in the back plate 85. On the other hand, the base member 517 has an outer diameter of the screw member 53.
An insertion hole 539 having a diameter slightly larger than that of the nut 7 and smaller than the outer diameter of the nut 538 is formed.

Since the locked state due to is released, the base member 517 is deviated from the shaft member 542.

In this case as well, when replacing the base member 517, it is not necessary to remove the shaft member 542 fixedly mounted on the back plate 85 from the back plate 85, so that the mounting strength of the housing case 500 is reduced each time it is replaced. In the state where the housing case 500 is removed, the base member 5
17 can be easily replaced.

The holding means shown in FIG. 17 is composed of two metal rail members 546 which are embedded in the front side of the back plate 85 so as to be vertically separated from each other. The rail member 546 is non-detachably fixed to the back plate 85 by a plurality of rivets 550, and, as shown in FIGS. A groove portion 548 is formed which is movable in the longitudinal direction in a state in which a substantially L-shaped locking piece 547 formed to bend inward is locked so as not to deviate. A wide portion 549 having a predetermined length is formed at a substantially central portion of the groove portion 548 so that the locking pieces 547 formed on the base members 517 and 518, respectively, having a predetermined length can be inserted therein.

When the base members 517 and 518 are attached to the back plate 85, after the respective locking pieces 547 are inserted from the central wide portion 549 into the inside of the rail member 546, the base members 517 and 518 are attached to the left and right sides of the groove portion 548.
