[Basic operation of pachinko machines]
When the launch handle 8 is turned and operated in a state where the game balls are stored in the upper plate 6, the game balls are launched toward the game board 4. When the launched game ball wins a start opening 14 or a winning opening (not shown), a predetermined number of game balls are paid out as winning balls. Further, when the game ball passes through the gate (not shown), the normal symbol display device 20 displays the variation of the normal symbol, and when the stop symbol is a predetermined hit symbol, it is provided at the start port 14. The ordinary electric accessory 14a is opened for a predetermined time. When the game ball wins the start opening 14, the special symbol display device 18 and the production symbol display device 19 display the special symbols and the variation of the production symbols related to the special symbols, and these symbols are determined in advance. When the player stops at the hit arrangement, the player becomes a big hit mode in which the player can acquire many game balls.
Hereinafter, various game modes of the pachinko gaming machine 1 that are switched in response to the start or end of a big hit will be described with reference to FIG.

(1) Normal game mode In this mode, a low probability (for example, 1/300) is applied among the two stages of jackpot probabilities in the special symbol lottery. In this mode, the normal symbol lottery cycle is long.
(2) Big hit mode This mode is executed when the special symbol (effect symbol) stops in a predetermined hit arrangement, and the special electric accessory 15a provided in the big prize opening 15 is opened. This releasing operation is repeated over a predetermined number of rounds (for example, 15 rounds), with a predetermined time (for example, 30 seconds) or a predetermined number of winnings (for example, 10 balls) as one round.

That is, the terminal surface case 42, the non-terminal surface case 43, and the main control board 23 constitute a single unit, and this unit (hereinafter simply referred to as “substrate case unit 350”) is attached to the back surface of the pachinko gaming machine 1. By attaching, the main control board 23 can be attached to the pachinko gaming machine 1.

  The terminal surface case 42 is integrally formed of a transparent resin, and includes a connector housing portion 42h, a cable insertion hole 42a formed in the connector housing portion 42h, and a terminal hole 42b, a through hole 42c, and a through hole. 42d, an engagement ring portion 42e, a hinge pin engagement portion 42f, a main body fixing portion 42g, and the like.

  The connector housing portion 42h has a housing space for housing the first connector 38 (connector housing of the first connector 38) therein, and is provided with a specific terminal 36A provided on the main control board 23 in the terminal surface case 42. A protruding shape is formed at a corresponding position. For example, the connector housing portion 42h of the present embodiment protrudes around the terminal hole 42b that exposes the specific terminal 36A to the outside, and the left and right side wall portions 42i that face the left and right side surfaces of the first connector 38, A ceiling portion 42j facing the upper surface of the first connector 38 is provided, and an opening 42k is formed on the front surface.

  The cable insertion hole 42a is formed corresponding to a specific terminal 36A provided on the main control board 23. Specifically, the cable insertion hole 42a is formed in the ceiling part 42j facing the terminal hole 42b in the accommodation space.

  The terminal holes 42b are holes for exposing the terminals 36 provided on the main control board 23 to the outside of the case, and a plurality of terminal holes 42b are formed according to the number of terminals 36 provided on the main control board 23. Then, the cable connection structure unique to the present invention is applied to the specific terminal 36A described above, and the cable connection structure similar to the conventional one is applied to the other terminals 36B. However, all the terminals provided on the main control board 23 are applied. The cable connection structure of the present invention may be applied to the terminal 36.

  The through hole 42c (female screw) is a hole into which a board fixing screw 40 (male screw) for fixing the main control board 23 to the terminal surface case 42 is screwed, and the through hole 42d is described later with the terminal surface case 42. This is a hole into which a case closing screw 41 for fixing the non-terminal surface case 43 is inserted or screwed.

The hinge pin engaging portion 42 f is a portion that serves as a pivot for the non-terminal surface case 43 when the substrate case unit 350 is opened and closed.
The main body fixing portion 42g is a portion into which a mounting pin (not shown) is inserted when fixing the substrate case unit 350 to the gaming machine main body.

The non-terminal surface case 43 is also integrally formed of a transparent resin, and includes a through hole 43a, a boss portion 43b, a hinge pin 43c, a main body engaging portion 43d and the like which will be described later.
The through hole 43 a is a hole into which the case closing screw 41 is inserted or screwed, and corresponds to the position of the through hole 42 c formed in the terminal surface case 42.

The hinge pin 43c is engaged with the hinge pin engaging portion 42e of the terminal surface case 42, and when the terminal surface case 42 and the non-terminal surface case 43 are attached / detached, that is, when the board case 35 is opened / closed, the non-terminal surface case 43 is a portion that becomes a pivotal support point.
The main body engaging portion 43d is a portion that is engaged and held by the pachinko gaming machine main body.

  Here, the relative positions of the terminal surface case 42 and the non-terminal surface case 43 are fixed by a known sealing structure 34 in a state where the main control board 23 is covered. That is, the relative position between the terminal surface case 42 and the non-terminal surface case 43 is not changed unless the sealing of the sealing structure 34 is released. As described above, the sealing structure 34 may be any known structure. For example, the sealing structure 34 is formed on the engagement ring portion 42e provided on the terminal surface case 42 and the terminal surface case 42. The boss portion 43b is provided on the non-terminal surface case 43 so as to correspond to the position of the engagement ring portion 42e. Note that a plurality of engagement ring portions 42e and a plurality of boss portions 43b may be formed in accordance with the number of sealable times.

  Such a sealing structure 34 is employed in a gaming machine in order to detect an illegal act performed on the control board at an early stage. More specifically, when the sealing structure 34 is opened, a trace of opening remains on the sealing structure 34. This trace has a function of notifying the administrator of the pachinko gaming machine 1 that the fixing of the terminal surface case 42 and the non-terminal surface case 43 has been released, that is, that the substrate case 35 has been opened. . In other words, the sealing structure 34 can prevent a fraudulent act against the main control board 23 to some extent.

  Next, the cable 37 will be described. The cable 37 includes a first connector 38 electrically connected to the terminal 36A on one end side, and a second connector 39 connected to the gaming machine main body side on the other end side. The connection structure 39 is a part of the attachment structure between the board case unit 350 and the pachinko gaming machine 1. That is, the main control board 23 and the gaming machine main body are connected or separated by connecting / disconnecting the connectors 38 and 39.

Next, the structure of the substrate case unit 350 and the cable 37 according to this embodiment that makes it difficult to separate the cable 37 and the main control board 23 (substrate case unit 350) will be described. First, as a premise, the outer shape of the connector housing of the first connector 38 is formed larger than that of the connector housing of the second connector 39. For example, when the first connector 38 has a connector housing with a left-right width W1 and a front-rear width D1, and the second connector 39 has a connector housing with a left-right width W2 and a front-rear width D2, the following relational expression holds: To do.
W2 <W1
D2 <D1

In addition, a cable insertion hole 42a that allows passage of the second connector 39 and restricts passage of the first connector 38 is formed in the connector housing portion 42h. That is, assuming that the cable insertion hole 42a has a lateral width W3 and a longitudinal width D3, the following relational expression is established.
W2 <W3 <W1
D2 <D3 <D1
Then, after connecting the first connector 38 in which the cable 37 is inserted into the cable insertion hole 42a to the terminal 36A of the main control board 23, the above-described through hole 23a, the board fixing screw 40 (male screw), and the penetration The terminal surface case 42 is fixed to the side of the main control board 23 on which the terminals 36 are arranged by fixing means constituted by the holes 42c (internal threads). Here, the state in which the cable 37 is inserted into the cable insertion hole 42a described above is a state in which the second connector 39 and then the cable 37 are passed through the cable insertion hole 42a from the inside of the housing space.

Furthermore, in the state where the terminal surface case 42 is fixed to the terminal surface of the main control board 23 as described above, the distance L between the first connector 38 inserted into the terminal 36A and the cable insertion hole 42a is the terminal It is set not to exceed the insertion stroke S of the first connector 38 with respect to 36A. That is, the distance L between the upper end of the first connector 38 and the lower surface of the ceiling portion 42j where the cable insertion hole 42a is formed is set so that the following relational expression is satisfied.
L <S
In this way, the first connector 38 cannot be detached from the terminal 36A unless the main control board 23 and the terminal surface case 42 are released and the relative positions of the two are changed. It is possible to prevent an illegal act of attaching an unauthorized device to 36A and impersonating an input / output signal of the main control board 23. Further, in an appropriate maintenance operation for removing the main control board 23 from the board case 35, the first connector 38 can be easily detached from the terminal 36A by releasing the fixation of the main control board 23 and the terminal surface case 42.

Next, a procedure for incorporating the main control board 23 into the board case 35 will be described.
First, the cable 37 is inserted into the cable insertion hole 42a of the terminal surface case 42 in the above-described procedure, and the first connector 38 of the cable 37 is accommodated in the connector accommodating portion 42h of the terminal surface case 42.
Next, the main control board 23 is housed in the terminal surface case 42 and fixed using the above-described fixing means. At this time, the first connector 38 is connected to the terminal 36 </ b> A of the main control board 23 in a plug-in manner substantially simultaneously with the main control board 23 being housed in the terminal surface case 42.
Next, the hinge pin 43c of the non-terminal surface case 43 is engaged with the hinge pin engaging portion 42f of the terminal surface case 42, and the substrate case 35 is closed using this as a rotation fulcrum.
Next, the case closing screw 41 is screwed into the through hole 42 d of the terminal surface case 42 from the non-terminal surface case 43 side through the non-terminal surface case 43 and the through holes 43 a and 23 b of the main control board 23. Thereby, the relative position of the terminal surface case 42 and the non-terminal surface case 43 is fixed, and the substrate case 35 is held in a closed state. When the substrate case 35 is closed, the screw heads of the substrate fixing screws 40 are accommodated in the substrate case 35.
Next, sealing is performed with the sealing structure 34. This sealing is performed by screwing a sealing screw 45 into the boss portion 43 b of the non-terminal surface case 43 via the engagement ring portion 42 e of the terminal surface case 42. The sealing screw 45 is a special screw that can only be turned in the screwing direction. After sealing, it is difficult to open the substrate case unit 350 unless the base end portion of the engagement ring portion 42e is cut. Become. That is, the opening of the sealing structure 34 leaves a trace of cutting of the base end portion. Here, once the sealing as described above is performed once, the screw head of the board fixing screw 40 is not operated unless the sealing is released.

  The sealed board case 35 (board case unit 350) is attached to the gaming machine main body via the main body fixing portion 42g and the main body engaging portion 43d. The second connector 39 of the cable 37 is connected to a predetermined terminal on the gaming machine main body side. In other words, the attachment structure for attaching the board case unit 350 to the gaming machine main body includes the main body fixing portion 42g, the main body engaging portion 43d, the connection between the first connector 38 and the terminal 36A, the second connector 39 and the gaming machine main body side. And a predetermined terminal.

Next, a procedure for properly removing the main control board 23 from the board case 35 will be described.
First, a cable (not shown) connected to the terminal 36B is disconnected.
Next, the substrate case unit 350 is removed from the gaming machine main body, and the sealing structure 34 is opened. This is done by cutting the proximal end portion of the engagement ring portion 42e.
Next, all the case closing screws 41 are removed, and the non-terminal surface case 43 is opened.
Next, all the board fixing screws 40 are removed, and the main control board 23 is taken out from the terminal surface case 42. At that time, the first connector 38 is disconnected from the terminal 36 </ b> A of the main control board 23 at substantially the same time as the main control board 23 is taken out from the terminal surface case 42.

  In this way, the work of removing the board case unit 350 from the gaming machine main body is the work of removing the first connector 38 that requires the release of the sealing structure 34 that requires time for a person who performs an illegal act, or the first connector 38. If the second connector 39 is not removed, the board case unit 350 cannot be removed from the gaming machine main body unless the second connector 39 is removed from the board case unit 350. Can be. As a result, it is possible to effectively prevent an illegal act of removing the genuine board case from the gaming machine body and replacing it with the unauthorized board case.

  Further, in order to perform maintenance, in the operation of removing the first connector 38 from the terminal 36A of the main control board 23, the first connector 38 can be connected from the terminal 36A of the main control board 23 without performing the destruction work in the vicinity of the terminal 36A. Can be removed. In addition, since the main control board 23 is covered with the terminal surface case 42, it is possible to prevent an illegal act of attaching an unauthorized instrument to the main control board.

  The second connector 39 provided on the other end side of the cable 37 is preferably not easily removed from the gaming machine main body side. For example, a structure in which the second connector 39 is disposed at a deep position in the gaming machine body, a structure in which the removal of the second connector 39 is regulated using a locking device, a structure in which the second connector 39 cannot be removed unless a tool is used, etc. Apply. In this way, the time required for the fraudulent act of removing the genuine board case to which the cable is connected by performing the removing operation of the second connector 39, and then replacing the genuine board case with the unauthorized board case to which the cable is connected.
