The projected tip is projected outside.
Therefore, when the lock 77 is locked in the locking hole 36, the opening / closing support plate 15 is in an unopenable state in the closed position.

On the other hand, the main control board 16 and the dispensing control board 19 are set in a state where the opening / closing support plate 15 is locked at the closed position.
When removing the lock 77, after the lock 77 is unlocked, the opening / closing support plate 15 is opened. That is, the knob 31 for disengagement, which projects laterally outward from the left end of the storage chamber 25, is further pushed laterally outward, and the engagement of the insertion piece 50 with the engagement hole 29 of the engagement piece 30. The locked state of the claw 51 is released. When the knob 52 of the opening / closing support plate 15 is gripped and rotated in the opening direction from that state, the opening / closing support plate 15 is set to the open position.

When the main control board 16 is to be removed with the opening / closing support plate 15 being in the open position, the fork-like elastic piece 73a of the hook 73 is operated on the inner surface side of the opening / closing support plate 15 by a fingertip operation. The direction in which the engagement portion 73c of the hook 73 is disengaged from the engagement opening 54 by the knob 73b being pinched, and the back surface of the protection case 69 of the main control board 16 is separated from the outer surface of the opening / closing support plate 15. Is rotated. Then, the hook 73 is inserted into the through hole 5 of the opening / closing support plate 15.
When the protective case 69 is lifted upward from this state, the shaft hole 7 of the projecting piece 76 extends from the support shaft 62.
5 is removed, and the main control board 16 is removed from the opening / closing support plate 15.

Similarly, when removing the dispensing control board 19 with the opening / closing support plate 15 being in the open position, the hook 33 in the storage chamber 25 is elastically deformed in the direction away from the dispensing control board 19 while The board 19 is slightly moved rightward to release the holding state of the board pressing piece 28 at the left end. Then, in this state, if the payout control board 19 is gripped, the board 19 is easily taken out from the accommodation room 25.

Therefore, according to the pachinko gaming machine of the present embodiment configured as described above, the following effects can be obtained. (1) Main control board 1 mounted on the outer surface side of opening / closing support plate 15
Reference numeral 6 denotes an open / close support plate 1 unless the lock (lock means) 77 is unlocked and the open / close support plate 15 is opened (the shaft 48 cannot be removed).
The engagement opening 54 that constitutes the engagement means 78 on the inner side of 5
Even if the front frame 2 is pivotally released from the outer frame 1 by the unauthorized player and the main control board 16 on the back side of the machine is exposed, the engagement state between the main control board 16 and the hook 73 cannot be released. Unauthorized detachment can be reliably prevented.

(2) The main control board 16 has a hook (engagement support member) 73 protruding from the back surface of a protective case (case body) 69 supported through the through hole 53 from outside the opening / closing support plate 15. In addition, in the penetrating support state, the engaging opening (other gaming machine component) 54 located inside the opening / closing support plate 15 is configured to be engaged with the through hole 53 of the opening / closing support plate 15. (Engagement support member) 7
The main control board 16 can be hooked and supported on the opening / closing support plate 15 for each case body by the through support structure 3.

(3) When the locking means consisting of the locking plate 35 and the lock 77 is unlocked, the opening and closing support plate 15 is pivotally opened to the open position to easily engage the lock inside the opening and closing support plate 15. Since the engagement means 78 is exposed, the engagement means 78
, That is, the engagement state of the hook 73 with the engagement opening 54 can be easily released, and the main control board 16 together with the protective case can be easily removed from the opening / closing support plate 15.

(4) In addition, since the protective case 69 of the main control board 16 is rotatably supported on the outer surface of the opening / closing support plate 15 with the support shaft 62 as a fulcrum, the protective case 69 is provided.
When inspecting the back side (there is a circuit pattern or the like) of the circuit board 66 housed in the inside, the protective case 69 is always checked.
The inspection work can be easily performed only by turning the support shaft 62 as a fulcrum without lifting the support from the opening / closing support plate 15. Then, from this state, if the protection case 69 of the main control board 16 is closed to the opening and closing support plate 15 side to insert the hook 73 into the through hole 53, the hook 73 is elastically deformed at the engagement opening 54. The main control board 16 can be opened and closed by a one-touch operation with a fingertip because it is inserted and connected.
Can be mounted on

(5) Further, a payout control board accommodated in the accommodation chamber 25 in a state of being partially overlapped with the main control board 16 and the electric control board 18 in the thickness direction (front-back direction) of the pachinko gaming machine. When the attachment / detachment 19 is replaced, the main control board 16 and the illumination control board 18 are mounted on the opening / closing support plate 15 and the support plate 15 is rotated to the open position to rotate the storage chamber. Since the 25 opening surfaces can be exposed, it is possible to quickly and easily carry out the attachment / detachment / exchange operation of the payout control board 19.

(6) On the other hand, the dispensing control board 19 is supported by the board mounting piece 26 from below while elastically engaging the hook 33 with the frictional locking action and the board pressing piece 2.
8 can be positioned and mounted in the storage chamber 25 by attaching the latching and retaining action by the mounting 8, so that mounting components such as screws can be omitted, and the mounting set configuration of the dispensing control board 19 can be simplified. On the other hand, when taking out the discharge control board 19 from the storage chamber 25, the board holding piece 2 is moved by moving the board 19 against the elastic force of the hook 33.
The substrate 19 can be easily taken out of the storage chamber 25 by releasing the latched holding state of 8, so that the attachment / detachment / exchange operation can be performed more quickly.

(7) When the opening / closing support plate 15 is pivotally opened from the closed position to the open position, the engagement release knob 31 is gripped to elastically deform the engagement piece 30 laterally outward. As a result, the engagement and locking state of the engaging claw 51 on the opening / closing support plate 15 side with respect to the engaging hole 29 of the engaging piece 30 is released. It can be pivotally opened to the open position side. Conversely, when the opening / closing support plate 15 in the open position is set to the closed position in the closed position, the insertion piece 50 of the support plate 15 slides on the engagement piece 30 with the closing operation of the opening / closing support plate 15. Abut on the engaging piece 3
0 is elastically deformed laterally outward.
And the engaging claw 51 are automatically fitted and locked to open and close the support plate 15.

(8) Moreover, since the opening / closing support plate 15 is made of a conductive iron plate, the electromagnetic wave is cut off by the opening / closing support plate 15 and the circuit board 66 of the main control board 16 and the like. Can be suitably protected.
Since the opening / closing support plate 15 has a member structure having a supporting function such as the main control board 16 and a member structure having the electromagnetic wave blocking function, the number of parts in the pachinko game machine is reduced. And contribute to cost reduction.

(9) In the main control board 16, a see-through window 79 is provided by forming a concave molding 80 in the cover member 68 of the protective case 69, and the circuit housed in the protective case 69 by the see-through window 78. Since the notation portion 81 of the electronic device 64 on the substrate 66 can be visually recognized at a glance, in a case where the electronic device 64 is improperly attached or detached, it is possible to quickly and easily find the illegal fact.

(10) In addition, since the surface 82 of the dent forming portion 80 facing the electronic device 64 is disposed close to the electronic device 64 so that the distance between the device and the electronic device 64 is small, a fraudulent player can use a wire or the like. Is inserted between the tray member 67 and the cover member 68 of the protective case 69 to detach the electronic device 64 from the connection portion 65 on the circuit board 66 in a direction orthogonal to the circuit board 66, but it is necessary for the attachment and detachment. It is possible to effectively prevent the unauthorized detachment by eliminating the space. Furthermore, even if the electronic device 64 is detached from the connection portion 65 by any means, the stopping leg portion 83 which is arranged close to the electronic device 64 by a small distance so as to surround the electronic device 64 as a movement stopping portion is moved from the detached position. Since the electronic device 64 is prevented from being moved in the direction parallel to the circuit board 66, the unauthorized attachment / detachment can be more effectively prevented.

(11) Further, the opposing surface 82 functioning as a detachable stopper and the stationary leg 8 functioning as a movement stopper.
3 is a configuration in which none of the components directly contact the surface of the electronic device 64 but is arranged close to the electronic device 64 at a slight distance, so that the tray member 6
When the cover member 68 is set on the electronic device 64, the electronic device 64 is not mechanically damaged by the opposing surface 82 and the stopping leg portion 83 when the cover member 68 is set. Even if the genuine electronic device after connection and replacement has a slightly different size in a standard manner, the difference in size can be absorbed by the small distance. In addition, since the stopping leg 83 is formed as a short plate piece having a trapezoidal side shape from the dent forming portion 80 having a rectangular parallelepiped shape, the stopping leg portion 83 cannot be easily broken by an illegal jig such as a wire. , Can reliably function as a stopping portion.
