The head 238 of the headed insertion pin 236 and the E-type retaining ring 248 are both locked by the upper end surface of the small diameter cylindrical portion 244 to prevent the headed insertion pin 236 from falling off during the assembly work of the control board storage box 200. Is done.
[0047]
FIG. 12A shows a state in which the dropout is prevented, that is, a state in which the E-type retaining ring 248 is fitted by inserting the headed insertion pin 236 attached with the spring 246 into the insertion pin insertion portion 208a. . As shown in this figure, an E-shaped retaining ring 248 is fitted slightly above the groove 250 of the headed insertion pin 236 provided with a spring 246. As a result, the spring 246 and the E-shaped retaining ring 248 are locked to the small-diameter cylindrical portion 244 as described above, so that the headed insertion pin 236 is prevented from falling off the insertion pin insertion portion 208a.
[0048]
12B shows a state in which the head portion 238 of the headed insertion pin 236 is struck with a screwdriver or the like, and the groove portion 250 formed around the tip portion of the pin main body portion 242 is locked in the insertion fitting hole 228a. It is shown. As shown in this figure, the groove portion 250 is engaged with the insertion fitting hole 228a, but the diameter of the groove portion 250 is the same as the diameter of the insertion fitting hole 228a (a slight error is allowed). It is formed in the size.
[0049]
That is, the insertion fitting hole 228a opens to a diameter that allows the pin main body portion 242 to be inserted when the headed insertion pin 236 is inserted. This is because a radial cut 230 is provided, and the opening and closing of each cut piece 231 (see FIG. 10) is slightly effective. Further, it depends on the material characteristics of the stainless spring material forming the insertion pin fixing base 210. Further, after the groove portion 250 is locked in the insertion fitting hole 228a, the insertion fitting hole 228a is not fixed in the insertion pin as shown in FIG. This is because it is formed in a bulging shape that is often recessed on the lower surface side of the base 210.
[0050]
Further, as shown in FIG. 12B, the headed insertion pin 236 is urged in the direction opposite to the insertion direction by a spring 246 inserted between the head 238 and the small diameter cylindrical portion 244. Due to this urging, an appropriate force is applied to each part of the insertion fitting hole 228a, the insertion pin insertion part 208a, and the head part 238. As a result, the insertion pin insertion portion 208a and the insertion pin fixing base 210 are securely fixed by the headed insertion pin 236 without wobbling. Similarly, the insertion pin insertion portions 208b to 208d and the corresponding insertion fitting holes 228b to 228d are inserted by inserting the headed insertion pin 236 by a driver or the like, and the groove portion 250 is inserted by the insertion fitting holes 228b to 228d. The cover member 202 is securely attached to the case member 204.
[0051]
Accordingly, a long insertion pin fixing base mounting portion 206 is provided on both the left and right side surfaces of the case member 204, and the cover member 202 has a plurality of insertion pin insertion portions 208a corresponding to the left and right side surfaces. To 208d, the cover member 202 is attached in a state where the main board 91 is housed in the case member 204, and from the insertion pin insertion portions 208a to 208d side of the cover member 202, the insertion pin fixing base 210 side of the case member 204 The case member 204 and the cover member 202 are integrally assembled by inserting the headed insertion pin 236.
[0052]
Assembling and mounting of the cover member 202, the case member 204, and the main board 91 described above are performed using the headed insertion pin 236 as follows. First, the main board 91 is sandwiched between the ribs 212a and 212b and the claws 214 shown in FIG. 8, the screws 220a and 220b are inserted into the screw insertion holes 218a and 218b, respectively, and screwed into the bosses 216a and 216b. The substrate 91 is accommodated and fixed in the case member 204. At this time, since the screws 220a and 220b penetrate the bosses 216a and 216b, the penetrated portions are screwed to the left and right brackets 184a and 184b on the back of the game board, and the case member 204 is attached to the back of the game board.
[0053]
Then, the screws 222a and 222b are inserted into the screw insertion holes 226a and 226b, respectively, and screwed into the bosses 224a and 224b, thereby fixing the insertion pin fixing base 210 to the insertion pin fixing base mounting portion 206. At this time, since the screws 222a and 222b penetrate the bosses 224a and 224b, the penetrated portions are screwed to the left and right brackets 184a and 184b on the back of the game board to further attach the case member 204 to the back of the game board. Make sure.
[0054]
Next, the cover member 202 is attached to the case member 204. Prior to this, the spring 246 is inserted into the headed insertion pin 236, and in this state, the headed insertion pin 236 is inserted into the insertion pin. The insertion parts 208a to 208d are inserted. Then, an E-type retaining ring 248 is fitted in a position slightly closer to the head side of the groove portion 250. This prevents the headed insertion pin 236 from falling off the insertion pin insertion portion 208a during the assembly operation.
[0055]
Then, the cover member 202 is covered from the upper side of the main board 91, the insertion pin insertion portions 208a to 208d are aligned with the insertion fitting holes 228a to 228d, and the head portion 238 of the headed insertion pin 236 is struck with a screwdriver into the groove portion 250. The insertion fitting holes 228a to 228d are locked.
[0056]
Then, the screws 220a and 220b are covered with the screw cover pieces 232, and the screws 222a and 222b are covered with the screw cover pieces 234a and 234b, so that the screwing portions are covered from the outside. Therefore, even if it is attempted to take out the main board 91 for the purpose of fraud, the fraud cannot be done unless these screw cover pieces 232 or screw cover pieces 234 are separated using a nipper or the like. In addition, even if a fraudulent act has been made, since there are traces of scratching and opening each member using nippers etc., it is necessary to deal with the act immediately, for example using such pachinko machines It is possible to deal with such as canceling.
[0057]
Next, a second embodiment of the present invention will be described with reference to FIGS. 13A to 13D. In the first embodiment, a groove is formed in the headed insertion pin to form a locking portion, and the cover member and the case member are securely fixed by the biasing force of the spring. In the second embodiment, a bent opening / closing piece is provided in the headed insertion pin without forming a groove.
[0058]
FIG. 13A is an external perspective view of a headed insertion pin according to the second embodiment. As shown in the drawing, a bent opening / closing member 258 including four bending opening / closing pieces 256 elongated along the main body is fitted on the pin main body portion 254 of the headed insertion pin 252. The bent opening / closing piece 256 is formed with a valley-shaped bent portion 260 and a mountain-shaped bent portion 262. The length of the bending opening / closing member 258 in the longitudinal direction is formed to be shorter than the length of the pin main body 254, and the diameter thereof is larger than the diameter of an insertion pin receiving port (see FIG. 13C) described later. It is formed larger. Moreover, the diameter of the head 264 is formed larger than the diameters of the insertion pin outlet and the insertion pin fixing port (see FIG. 13C), which will be described later.
[0059]
FIG. 13B schematically shows the appearance of the cover member 266 and the case member 268 in which the headed insertion pin 252 is used. As shown in this figure, the insertion pin insertion portions 270 into which the headed insertion pins 252 are inserted are provided at two positions on the left and right wall surfaces of the cover member 266 at two intervals, and are inserted. The insertion pin fixing portions 272 that fix the headed insertion pins 252 are provided on the left and right side wall surfaces of the case member 268 corresponding to the insertion pin insertion portions 270. The insertion pin insertion part 270 is formed slightly smaller than the insertion pin fixing part 272.
[0060]
FIG. 13C shows a state in which the headed insertion pin 252 is inserted from the insertion pin insertion portion 270 toward the insertion pin fixing portion 272. As shown in this figure, the insertion pin insertion portion 270 is formed so that the diameter of the insertion pin insertion port 274 is the same as the diameter of the head 264, and the diameter of the insertion pin outlet 276 is a bending opening / closing member. It is formed in the same size as the diameter of 258, and the inside is formed in a hollow shape. When the headed insertion pin 252 is locked by the bending opening / closing member 258, the ball 278 is placed on the insertion pin insertion port 274. The ball 278 having a diameter larger than that of the insertion pin insertion port 274 is used. Moreover, the cavity of the insertion pin insertion part 270 is formed in a size that allows the head 264 and the ball 278 to be stored exactly.
[0061]
On the other hand, the insertion pin fixing portion 272 is formed so that the diameter of the insertion pin fixing port 280 is the same as the diameter of the bending opening / closing member 258, that is, the diameter of the insertion pin outlet 276 described above. The diameter is substantially the same as the diameter of the pin main body 254. Therefore, the diameter of the insertion pin fixing port 280 is formed to be slightly larger than the diameter of the insertion pin receiving port 282 as much as the bent opening / closing member 258 is attached. And the inside of the insertion pin fixing | fixed part 272 is formed in a cavity shape, and the bending | flexion opening / closing piece 256 bends in this cavity.
[0062]
FIG. 13D shows a state where the ball 278 is press-fitted into the cavity of the insertion pin insertion portion 270 from the insertion pin insertion port 274. Since the cover member and the case member are formed of plastic resin or the like, even if the insertion pin insertion port 274 is smaller than the diameter of the ball 278, the insertion pin insertion can be performed by biasing the ball 278 with an appropriate force. The mouth 274 opens and closes according to the diameter of the ball 278 that passes therethrough. When the ball 278 is press-fitted into the insertion pin insertion portion 270 in this way, the urging force is transmitted to the headed insertion pin 252 and the headed insertion pin 252 is further inserted in the insertion direction by the force. Is done.
[0063]
At this time, since the tip of the bending opening / closing piece 256 is locked at the upper end of the insertion pin receiving port 282, the valley-shaped bending portion 260 of the bending opening / closing piece 256 is bent into a valley shape and the mountain-shaped bending portion 262 is recoiled. Is bent in a mountain shape, and the bent opening / closing member 258 is opened in the cavity. Then, the mountain-shaped bent part 262 comes into contact with the wall surface in the insertion pin fixing part 272. Thus, the headed insertion pin 252 is securely fixed at the tip of the bent opening / closing member 258. In particular, wobble in the lateral direction (direction perpendicular to the insertion direction) is avoided.
[0064]
As for the vertical direction (insertion direction), the length from the insertion pin insertion port 274 to the tip of the insertion pin receiving port 282 is exactly equal to the length of the ball 278 and the headed insertion pin 252 plus the length. In addition, since the diameter of the ball 278 is larger than the diameter of the insertion pin insertion port 274, the ball 278 and the headed insertion pin 252 are attached without a gap. Therefore, wobbling of the headed insertion pin 252 in the vertical direction is avoided.
[0065]
The above-described assembly of the cover member 266, the case member 268, and the main board 91 is performed using the headed insertion pin 252 as follows. First, the main board 91 is accommodated and fixed in the case member 268. Next, the cover member 266 is attached to the case member 268, the insertion pin insertion portion 270 and the insertion pin fixing portion 272 are aligned, and the headed insertion pin 252 is inserted from the insertion pin insertion portion 270 into the insertion pin. Insert toward the fixing portion 272. Next, after placing the ball 278 in each insertion pin insertion port 274, the ball 278 is press-fitted into the insertion pin insertion portion 270. As a result, the main board 91 is housed and fixed to the cover member 266 and the case member 268.
[0066]
Therefore, even if it is attempted to take out the main board 91 for the purpose of fraud, the headed insertion pin 252 is blocked by the ball 278 and cannot be seen from the outside, so that if the insertion pin insertion port 274 is not cut, it is illegal. I can't act. Even if a fraudulent act is carried out, since the traces of scratching and opening each member remain, it is possible to take measures such as stopping the use of the pachinko gaming machine related to the fraudulent act.
[0067]
Next, a third embodiment of the present invention will be described with reference to FIGS. 14A to 14C.
