  The latch receiver 121 includes a closing portion 129 that closes the slit-shaped latch receiver 121 on the connecting wall 127 side opposite to the receiver 128. However, the closing portion 129 is formed at the end of the locking receiver 121 opposite to the side where the receiving portion 128 is formed. Further, the closing portion 129 does not close the entire slit-shaped locking receiver 121 but only a part thereof.

  In the state where the front side structural body 101 and the back side structural body 102 are integrated, as shown in FIGS. 10 (a) and 10 (b), the hook portion 111 is inserted into the locking receiver 121, As shown in FIG. 10A, the receiving portion 128 of the locking receiver 121 is inserted into the locking groove 117 of the hook portion 111. The receiving portion 128 is in contact with the frame portion 112 and is in contact with the extending portion 116 of the hook portion 111.

  In this case, even if the front side structure 101 and the back side structure 102 are moved and separated in the entering direction of the receiving part 128 with respect to the locking groove 117, the receiving part 128 is provided on the standing part 115 of the front side structural body 101. It is regulated by contacting. Further, even if the front side structural body 101 and the back side structural body 102 are separated in the thickness direction of the substrate box 92, they are restricted by the contact between the hook portion 111 and the receiving portion 128. Further, as shown in FIG. 10B, the hook portion 111 is sandwiched between both the lower peripheral wall portion 123 and the inner wall portion 126 constituting the locking receiver 121. Therefore, even if the front side structural body 101 and the back side structural body 102 are moved up and down to be separated, the hook portion 111 is regulated by contacting either the lower peripheral wall portion 123 or the inner side wall portion 126. . That is, the direction in which the front side structure 101 and the back side structure are separated by the hook portion 111 and the locking receiver 121 is the direction in which the receiving portion 128 is extracted from the locking groove 117, that is, one short side of the substrate box 92. It is regulated on the side.

  In particular, a plurality of combinations of the hook portion 111 and the locking receiver 121 are provided on both long side portions of the substrate box 92, and further, these combinations are substantially the same in the length direction of each long side portion. It is performed at positions dispersed throughout. Therefore, the above regulations are strictly enforced.

  As shown in FIG. 10B, in the restricted state where the hook portion 111 is inserted into the locking receiver 121 and the receiving portion 128 is inserted into the locking groove 117, the lower frame portion 114 of the front side structure 101. Are overlapped in the thickness direction of the lower pedestal 125 and the substrate box 92. In this case, the lower frame portion 114 is overlapped over the entire lower pedestal portion 125, and the inner space of the substrate box 92 is formed in the long side portion of the substrate box 92 by the lower pedestal portion 125 and the lower frame portion 114. A part of the peripheral surface is configured.

  As described above, the lower frame portion 114 is provided so as to stand from the base portion 110 of the front side peripheral edge portion 103 toward the back side structure 102. Further, the lower pedestal portion 125 is a portion constituting the slit-like locking receiver 121 as described above, and accordingly, is formed thicker than the lower frame portion 114. Further, the lower frame portion 114 is disposed at a position biased toward the lower peripheral wall portion 123 so as to contact the lower peripheral wall portion 123 on the lower pedestal portion 125. Therefore, as shown in FIG. 10B, a predetermined gap is formed between the base portion 110 that continues to the lower frame portion 114 and the lower pedestal portion 125, and the main control board 91 is formed in the gap. Part of the peripheral edge of

  As described above, the lower peripheral wall portion 123 of the back-side structure 102 protrudes to the front-side structure 101 side with respect to the lower pedestal portion 125, and the protruding portion is outward with respect to the outer side surface of the lower frame portion 114. Are overlapping. Further, the lower peripheral wall portion 123 has an end surface on the leading end side thereof that is flush with the surface of the base portion 110 in the front peripheral edge portion 103. That is, the lower peripheral wall portion 123 overlaps the entire outer peripheral surface of one long side portion in the front side peripheral edge portion 103. Due to this configuration, the boundary of the long side portion between the front-side structure 101 and the back-side structure 102 is linear as shown in FIG.

  Moreover, the said boundary exists in the outer side rather than the base part 110 of the front side peripheral edge part 103, as shown in FIG.10 (b). Even if a fraudulent jig such as a lead wire is inserted into the internal space of the board box 92 through the boundary, the lower frame part 114 and the lower pedestal part 125 overlap with each other as described above. Is blocked. Furthermore, since the restriction by the hook portion 111 and the locking receiver 121 is firmly performed as described above, even if the lower frame portion 114 and the lower pedestal portion 125 are separated from each other, this is firmly prevented. .

  Here, by providing the hook portion 111 and the locking receiver 121 as described above, the restriction on the separation direction of the front side structure 101 and the back side structure 102 can be achieved while reducing the size of the substrate box 92. It is done firmly. This configuration will be described using FIG. 11 in comparison with a configuration in which the size of the board box 92 is increased. FIG. 11A is a cross-sectional view showing a restriction location of the substrate box 92 in the pachinko machine 10, and FIG. 11B is a cross-sectional view showing a restriction location of the substrate box 131 to be compared.

  The board box 92 of the pachinko machine 10 is provided with the hook part 111 and the locking receiver 121 as described above, so that the board can be moved from the edge of the internal space of the board box 92 to the board as shown in FIG. The distance to the peripheral surface of the box 92 is X1.

  On the other hand, in the board box 131 to be compared, as shown in FIG. 11B, the hook portion 132 and the locking receiver 133 are in a reverse relationship with the board box 92, and the front side structure 134 and It is formed on the back side structure 135. That is, the hook portion 132 is formed on the back-side structure 135, and the locking receiver 133 is formed on the front-side structure 134. Further, in the substrate box 92, the edge portion of the front side structure 101 provided with the hook portion 111 constitutes a part of the peripheral surface of the internal space in the substrate box 92, but in the substrate box 131, the hook portion 132 is formed. The edge part of the provided back side structure 135 does not constitute a part of the peripheral surface of the internal space. Therefore, the distance from the edge of the internal space of the substrate box 131 to the peripheral surface of the substrate box 131 is X2, which is longer than the distance X1 of the corresponding portion in the substrate box 92 by X3.

  As described above, according to the substrate box 92 of the pachinko machine 10, the separation of the front side structure 101 and the back side structure 102 is firmly regulated while the size of the substrate box 92 is reduced. In the pachinko machine 10, it is preferable to increase the size of the display screen of the symbol display device 41 and to make the pachinko machine 10 multifunctional. However, if an attempt is made to increase the size of the display screen or to make the pachinko machine 10 multifunctional, a space for mounting electrical devices on the back side of the pachinko machine 10 is limited. In contrast, by reducing the size of the substrate box 92 as described above, it is possible to satisfactorily realize an increase in the size of the display screen and the increase in the number of functions of the pachinko machine 10.

  Next, the assembling work of the front side structural body 101 and the back side structural body 102 by the restriction means will be described with reference to FIG. FIGS. 12A to 12C are explanatory views for explaining the assembly work of the front side structural body 101 and the back side structural body 102.

  When the front-side structure 101 and the back-side structure 102 are fixed to each other, first, the hook portion 111 is engaged from the back side of the back-side structure 102 so that the state shown in FIG. 12A is changed to the state shown in FIG. Insert into the catch 121. In this case, the free end of the hook part 111 faces the receiving part 128 side in the inserted locking receiver 121. Further, in this state, the front-side structure 101 and the back-side structure 102 are not completely overlapped but are shifted in the left-right direction.

  After that, at least one of the front-side structure 101 or the back-side structure 102 is slid in the direction in which both the structures 101 and 102 are completely overlapped, as shown in FIG. The receiving portion 128 of the locking receiver 121 enters the working groove 117. Thereby, the moving direction of the front side structural body 101 and the back side structural body 102 is regulated so as to be movable only in the direction in which the receiving portion 128 is removed from the locking groove 117. In this state, the fixing by the fixing means makes it impossible to move in the movement direction restricted by the restricting means, and the front structure 101 and the back structure 102 are fixed to each other.

In this case, the hook plate portion 163 is in a state of being hooked on the inner groove wall portion 156 among the wall portions forming the groove portion 155 in the coupling region forming portion 152. Further, as shown in FIGS. 9 and 14, among the opposing plate portions 164 and 165 of the receiving base portion 162, the outer opposing plate portion 165 is formed with a plurality of locking recesses 167. Correspondingly, as shown in FIG. 9, a locking portion 158 is integrally formed on the outer groove wall portion 157 among the wall portions defining the groove portion 155 in the coupling region forming portion 152. The locking portions 158 are formed at a plurality of locations in a one-to-one correspondence with the locking recesses 167.

  In a state where the receiving member 153 is installed in the coupling region forming portion 152, the locking recess 167 is locked by the locking portion 158, and the receiving member 153 is fixed to the coupling region forming portion 152. In a state where the receiving member 153 is fixed to the coupling region forming portion 152, the recessed space 161 in the receiving base portion 162 is opened toward the front-side component 101, and the receiving base portion 162 is substantially entirely in the groove portion 155. It is located across.

  That is, as shown in FIG. 8, the receiving member 153 is located over substantially the entire short side of the substrate box 92. In other words, the receiving member 153 is provided so as to be located over the whole or substantially the whole between the corner portions of at least a predetermined peripheral surface portion of the plurality of peripheral surface portions of the substrate box 92. In other words, the substrate box 92 is formed in a polygonal shape (rectangular shape) when viewed from the front, and the receiving member 153 is located over the whole or substantially the entire extending direction of the side of the predetermined side.

A plurality of locking pieces 168 are formed at equal intervals, and this number is the same as the number of front side coupling portions 142 formed in the front side coupling region 141 and corresponds to the position of the front side coupling portion 142. Is formed.

  As described above, the cover member 154 is installed on the coupling region forming portion 152 to which the receiving member 153 is fixed. The cover member 154 is formed of a colorless and transparent polycarbonate resin, but the forming material is not limited to this, and may be an acrylic resin or the like. The cover member 154 has the same or substantially the same length as the coupling region forming part 152, and has a function of covering the whole or substantially the whole of the coupling region forming part 152 and the receiving member 153. It has a function for partitioning the coupling region forming portion 152 to which the member 153 is fixed into the same number of back side coupling portions 176 as the front side coupling portion 142.

  Specifically, as shown in FIG. 13, the cover member 154 includes a first cover plate portion 172 and a second cover plate portion 173 orthogonal to the first cover plate portion 172. 171. When the cover member 154 is installed in the coupling region forming portion 152, the first cover plate portion 172 has the groove walls 156 and 157 facing the coupling region forming portion 152 and the receiving member 153 fixed to the coupling region forming portion 152. On the other hand, the second cover plate portion 173 overlaps the entire outer peripheral surface of the outer groove wall portion 157 in the coupling region forming portion 152 from the outside, overlapping from the open side of the recessed space 161 of the receiving member 153. ing.

  As shown in FIG. 15A, the first cover plate portion 172 is formed with a plurality of through-hole portions 174 at equal intervals in the length direction. By forming the through hole portion 174, the recessed space 161 of the receiving member 153 is not completely closed by the first cover member 154, and is directed toward the front-side component 101 at the position of the through hole portion 174. Open.

  The through-hole portion 174 has a one-to-one correspondence with the locking piece 168 of the receiving member 153, and as shown in FIG. 13, one through-hole portion 174 and one position aligned with the substrate box 92 in the thickness direction. The locking piece 168 is located. Further, the through-hole portion 174 corresponds to the front side coupling portion 142 on a one-to-one basis.

  On the surface side of the first cover plate portion 172, as shown in FIGS. 15 (a) and 15 (b), regions where the through-hole portions 174 are formed on the surface side of the first cover plate portion 172 are individually provided. A partition wall 175 is integrally formed so as to partition. And the back side coupling | bond part 176 is comprised by each area | region divided by the division wall part 175. FIG. Each back side coupling part 176 is opened toward the front side structure 101 and is also opened toward the short side part facing the short side part on the side where the back side coupling region 151 is formed in the back side structure 102. Yes. Each back side coupling portion 176 has a size that can accommodate the corresponding front side coupling portion 142, and in the state where each front side coupling portion 142 corresponding to each back side coupling portion 176 is accommodated, The through-hole part 143 and the through-hole part 174 of each back side coupling | bond part 176 will be in the state connected.

  As shown in FIG. 15B, positioning protrusions 177 are formed at a plurality of locations on the back surface side of the first cover plate portion 172. When the cover member 154 is installed, these positioning protrusions are formed. By setting 177 into the recessed space 161 of the receiving member 153, the installation location can be easily positioned. Further, when the projection 177 enters the recessed space 161 of the receiving member 153, the removal direction when the cover member 154 is detached from the installation location is the direction in which the recessed space 161 is opened, that is, from the back side structure 102. It is regulated in the direction toward the front side structure 101.

  Next, the flow of work in forming the back side coupling region 151 will be described with reference to FIG. FIGS. 16A to 16C are explanatory views for explaining the work in forming the back side coupling region 151.

  As shown in FIG. 16B, a receiving member 153 is installed on the coupling region forming portion 152 of the back side structure 102 shown in FIG. In the installation, the receiving base portion 162 of the receiving member 153 enters the groove portion 155 of the coupling region forming portion 152 and the hooking plate portion 163 of the receiving member 153 is hooked on the inner groove wall portion 156 of the coupling region forming portion 152. It is performed so that it will be in the state.

  As shown in FIG. 16B, the receiving base portion 162 of the receiving member 153 is overlapped with the inner peripheral surface of the groove portion 155 of the coupling region forming portion 152, so that the locking recess 167 of the receiving base portion 162 is engaged. Is locked by the locking portion 158 of the coupling region forming portion 152. The locking portion 158 has a tip protruding into the groove portion 155, but the locking portion 158 is formed to be elastically deformable to a position that does not hinder the entry when the receiving base portion 162 enters the groove portion 155. ing.

  Thereafter, as shown in FIG. 16C, the cover member 154 is installed in the coupling region forming portion 152 where the receiving member 153 is installed. At this time, since the positioning projection 177 is formed on the cover member 154, the cover member 154 can be installed satisfactorily. When the cover member 154 is installed, the locking portion 158 is covered from the outside by the cover member 154. Further, the portion where the locking portion between the locking portion 158 and the locking recess 167 at the opening portion of the groove portion 155 is exposed is also covered with the cover member 154. As a result, even if the locking state between the locking portion 158 and the locking recess 167 is illegally released, the act becomes difficult to perform.

  Installation of the cover member 154 completes the formation of the back side coupling region 151. In this case, a fixing tool for fixing the cover member 154 to the coupling region forming portion 152 and the receiving member 153 is not provided, and the cover member 154 is not fixed to the coupling region forming portion 152 and the receiving member 153.

  Next, the coupling | bonding of the front side coupling | bond part 142 and the back side coupling | bond part 176 is demonstrated using FIG. FIG. 17 is a cross-sectional view showing a connecting portion between the front side connecting portion 142 and the back side connecting portion 176 in the substrate box 92.

  In a state where each front side coupling portion 142 corresponding to each back side coupling portion 176 is accommodated, as described above, the corresponding penetration formed in the through hole portion 143 and the first cover plate portion 172 of each front side coupling portion 142. The hole 174 is in communication with the hole 174. As shown in FIG. 17, a metal coupler (fixing tool) 181 is inserted into the through-hole portions 143 and 174 communicated with each other from the front-side coupling portion 142 side, so that the front-side coupling portion 142 is inserted. And the back side coupling portion 176 are coupled (fixed).

  That is, the engaging hole 181a is formed in the coupler 181, and the engaging piece 168 enters the engaging hole 181a by inserting the coupler 181. In this case, since the locking piece 168 functions as a leaf spring as described above, and the free end is directed to the back side of the recessed space 161, the movement of the coupler 181 in the insertion direction is not restricted. However, after the locking piece 168 enters the locking hole 181a, the movement of the coupler 181 in the extraction direction is restricted. Thereby, the front side coupling | bond part 142 and the back side coupling | bond part 176 are couple | bonded, and the front side structure 101 and the back side structure 102 are fixed.

  The coupler 181 is made of metal so as to have higher strength than the wall portion of the back-side structure 102, but is limited to metal as long as it is stronger than the wall portion of the back-side structure 102. It may be made of synthetic resin, may be formed of a material in which a reinforcing agent such as glass fiber is dispersed in a synthetic resin material, and surface treatment such as plating is applied to the material formed of the synthetic resin material You may form by giving.

  Here, as described above, the cover member 154 is provided in a non-fixed state with respect to the coupling region forming portion 152. However, the direction in which the cover member 154 is detached from the installation location is determined from the back side structure 102 by the projection 177. Since it is restricted in the direction toward the body 101, the movement in the direction in which the cover member 154 is detached is restricted when the front-side coupling portion 142 is superimposed on the back-side coupling portion 176. Then, the front side coupling portion 142 and the back side coupling portion 176 are coupled, so that the cover member 154 is sandwiched between the front side coupling portion 142 and the coupling region forming portion 152 and is fixed without play.

  As shown in FIG. 17, a receiving plate portion 185 is integrally formed on the cover member 154 so as to enter the internal space of the substrate box 92 from the first cover plate portion 172. As shown in FIG. 15 (b), the receiving plate portion 185 is provided at a plurality of locations so as to be located over the entire length of the cover member 154. As shown in FIG. A base end portion 186 extending from the one cover plate portion 172 toward the back side structural body 102 side, and a front end portion 187 extending from the base end portion 186 toward the center side of the internal space of the substrate box 92 are provided. The front end portion 187 of the receiving plate portion 185 is in contact with a support base portion 188 formed adjacent to the coupling region forming portion 152 in the back side structure 102 with the cover member 154 installed in the coupling region forming portion 152. . Further, the front end portion 187 of the receiving plate portion 185 is a state of the main control board 91 integrated with the frame portion 112 of the front side structural body 101 and the front side structural body 101 in a state where the front side structural body 101 is combined with the back side structural body 102. It will be in the state where the peripheral part got on. That is, the front end portion 187 of the receiving plate portion 185 is sandwiched between the support base portion 188 of the back side structure 102, the frame portion 112 of the front side structure 101, and the peripheral edge portion of the main control board 91. Thereby, the cover member 154 is fixed in a more stable state.

  Next, the work flow when the front side coupling portion 142 and the back side coupling portion 176 are in the coupled state will be described with reference to FIG. FIGS. 18A to 18C are explanatory diagrams for explaining the flow of work when the front side coupling portion 142 and the back side coupling portion 176 are in the coupled state.

  As shown in FIG. 18A, the front side structure 101 is combined with the back side structure 102 in a state where the receiving member 153 and the cover member 154 are installed in the coupling area forming portion 152 and the back side coupling area 151 is formed. Accordingly, as shown in FIG. 18B, the through-hole portion 143 of the front-side coupling portion 142 and the corresponding through-hole portion 174 of the back-side coupling portion 176 are in communication with each other. In this case, by making the state regulated by the regulating means including the hook portion 111 and the locking receiver 121, the front side coupling portion 142 naturally corresponds to each back side coupling portion 176 of the back side coupling region 151. The portion 142 is accommodated, and the through-hole portions 143 and 174 are communicated as described above.

  Thereafter, as shown in FIG. 18 (c), by inserting the coupler 181 from the front coupling portion 142 side into the through-hole portions 143 and 174 communicated, the front coupling in which the coupling 181 is inserted. The combination of the part 142 and the back side coupling part 176 is in a coupled state, and the front side structural body 101 and the back side structural body 102 are fixed. In this case, a plurality of combinations (specifically, five sets) of combinations of the front-side coupling portion 142 and the back-side coupling portion 176 are provided, and the coupler 181 is inserted into at least one of these combinations. Thus, the front side structure 101 and the back side structure 102 are fixed.

  Next, with reference to FIG. 19, a description will be given of the work flow when releasing the fixed state of the front side structure 101 and the back side structure 102 in a state where the front side connection part 142 and the back side connection part 176 are in the combined state. . FIGS. 19A to 19C are explanatory diagrams for explaining a work flow when the fixed state of the front side structure 101 and the back side structure 102 is released.

  When releasing the fixed state of the front side structure 101 and the back side structure 102, as shown in FIG. 19A, the connecting portion 144 between the front side connecting portion 142 and the bulging portion 104 that are in a connected state. In addition, the connecting portion 144 between the front side connecting portion 142 that is in the connected state and the front side connecting portion 142 that is not in the connected state is cut using a tool such as a nipper or a cutter. As a result, the separation between the front side structure 101 and the back side structure 102 is not hindered by the binding of the front side coupling part 142 and the back side coupling part 176.

  In this case, the connection part 144 is provided with respect to the front side coupling part 142, and the back side coupling region 151 is not destroyed. Therefore, the front side coupling portion 142 in the coupled state remains on the back side coupling region 151 side. In addition, the state in which the cover member 154 is fixed to the coupling region forming unit 152 through the coupling between the front side coupling unit 142 and the back side coupling unit 176 is obtained by leaving the front side coupling unit 142 in the coupled state in this way. Maintained.

  Thereafter, as shown in FIG. 19 (b), by sliding and moving at least one of the front side structure 101 or the back side structure 102 in the direction regulated by the regulation means comprising the hook portion 111 and the locking receiver 121, the hook The locked state between the portion 111 and the locking receiver 121 is released. After that, as shown in FIG. 19C, the front side structure 101 and the back side structure 102 are separated in the thickness direction of the substrate box 92, so that the structures 101 and 102 are completely separated. .

  In this case, since the connecting portion 144 is cut, it is possible to confirm whether or not the front-side structure 101 and the back-side structure 102 are separated by checking the cut portion of the connecting portion 144. Become. In addition, since a plurality of combinations of the front-side coupling portion 142 and the back-side coupling portion 176 are provided as described above, only a part of the combinations is coupled at the time of fixing once, so that the front-side structure 101 again. And the back side structure 102 can be fixed. However, the coupling process may be performed on all combinations of the front side coupling unit 142 and the back side coupling unit 176 at the time of fixing.

  Next, another fixing structure provided in the substrate box 92 will be briefly described.

  As shown in FIG. 8, a pasting plate portion 191 is provided on the short side portion of the substrate box 92 opposite to the side on which the front side binding region 141 and the back side binding region 151 are provided. The affixing plate part 191 is configured by superimposing an affixing plate part formed on the front-side component 101 and an affixing plate part formed on the back-side component 102. A seal seal 192 is attached to the sticking plate portion 191 so as to straddle the boundary between the two. When the seal seal 192 is peeled off after being stuck, the pressure-sensitive adhesive layer remains on the sticking plate portion 191 side, and re-sticking becomes impossible.

  A fixing portion 193 is provided on the short side portion of the substrate box 92 where the sticking plate portion 191 is provided so as to sandwich the sticking plate portion 191, and screws are fixed to the fixing portion 193. Thus, the front side structure 101 and the back side structure 102 are fixed.

  Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG. In FIG. 20, a power supply line is indicated by a double line arrow, and a signal line is indicated by a solid line arrow.

  The CPU chip 93 is provided with an input port and an output port. Connected to the input side of the CPU chip 93 are a power failure monitoring circuit 203 provided on the main control board 91, a payout control board 211 provided on the payout control device 82, and a switch group (not shown). In this case, the power failure monitoring circuit 203 is connected to a power source and launch control board 215 provided in the power source and launch control device 83, and power is supplied to the CPU chip 93 via the power failure monitoring circuit 203.

  On the other hand, a power failure monitoring circuit 203, a payout control board 211 and a relay terminal board 219 are connected to the output side of the CPU chip 93.

Various commands are output from the main control circuit 202 to the sound lamp control board 221 provided in the sound lamp control device 66 via the relay terminal board 219.

  The power failure monitoring circuit 203 relays between the main control circuit 202 and the power source and launch control board 215, and monitors a DC stable voltage of 24 volts that is the maximum voltage output from the power source and launch control board 215.

  The payout control board 211 performs payout control of prize balls and rental balls by the payout device 78. The CPU 212 that is an arithmetic unit includes a ROM 213 that stores a control program executed by the CPU 212, fixed value data, and the like, and a RAM 214 that is used as a work memory or the like.

  The CPU 212 of the payout control board 211 is provided with an input / output port. A main control circuit 202, a power and launch control board 215, and a back pack board 79 are connected to the input side of the CPU 212. The main control circuit 202 and the back pack substrate 79 are connected to the output side of the CPU 212.

  The power source and launch control board 215 includes a power source unit 216 and a launch control unit 217. The power supply unit 216 is connected to, for example, a commercial power supply (external power supply) in a game hall or the like. Then, based on the external power supplied from the commercial power supply, necessary operating power is generated for each of the main control circuit 202, the payout control board 211, etc., and the generated operating power is indicated by a double line arrow. This is supplied to the main control circuit 202 and the payout control board 211 through the path. The launch control unit 217 is responsible for launch control of the game ball launch mechanism 50, and the game ball launch mechanism 50 is driven when predetermined launch conditions are met.

  The sound lamp control board 221 controls the display control device 225. The CPU 222 that is an arithmetic unit includes a ROM 223 that stores a control program executed by the CPU 222, fixed value data, and the like, and a RAM 224 that is used as a work memory or the like.

  The CPU 222 of the sound lamp control board 221 is provided with an input / output port. A main control circuit 202 is connected to the input side of the CPU 222 through a relay terminal board 219 and controls the display control device 225 based on various commands output from the main control circuit 202. The display control device 225 controls the symbol display device 41 based on a display command input from the sound lamp control board 221.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  In the board box 92 of the main control device 63, the front side coupling part 142 and the back side coupling part 176 are coupled by the coupling tool 181, so that the separation of the front side structural body 101 and the back side structural body 102 is prevented. In this case, since the receiving member 153 that locks the coupling tool 181 in the back side structure 102 is made of metal, even if the locking portion between the receiving member 153 and the coupling tool 181 is broken to try to release the locking. It becomes difficult to do. In this configuration, the receiving member 153 is provided across all the back side coupling portions 176. Thereby, compared with the structure which installs the receiving member 153 with respect to each of each back side coupling | bond part 176, the formation operation | work of the board | substrate box 92 can be performed favorably. Further, the number of members of the receiving member 153 can be reduced as compared with the configuration in which the receiving member is individually installed for each of the back side coupling portions 176.

  Since the metal receiving member 153 is provided over substantially the entire length of the predetermined peripheral surface portion of the substrate box 92, the predetermined peripheral surface portion is broken to the internal space of the substrate box 92. It is possible to prevent the act of illegally forming the opening that leads to it. In addition, since the receiving member 153 constituting the fixing means fulfills the function of preventing the illegal act, the receiving member 153 can be multi-functional.

  The receiving member 153 includes a series of recessed spaces 161 formed with a width direction defined by a pair of opposing plate portions 164 and 165 facing each other, and a locking portion 158 corresponding to each back side coupling portion 176. Is formed in the recessed space 161. The locking with the coupler 181 is performed in the recessed space 161. That is, the locking portion of the coupler 181 is performed in the recessed space 161 defined by the metal receiving member 153. Therefore, even if it is attempted to release the locked state by destroying the surroundings of the locked portion, it becomes difficult to do so, and it is possible to prevent such illegal acts. In addition, the above-described excellent effect can be obtained for each back-side coupling portion 176 by a relatively simple configuration in which a plurality of locking portions 158 are provided in the series of recessed spaces 161.

  In addition, a pair of opposed plate portions 164 and 165 that form the recessed space 161 are provided so as to be located over substantially the entire length of a predetermined peripheral surface portion of the substrate box 92. Therefore, compared to the configuration in which one plate portion is provided, the strength of the predetermined peripheral surface portion is increased, and the predetermined peripheral surface portion is destroyed and attempts to illegally form an opening leading to the internal space of the substrate box 92 Can be prevented.

  The back side structure 102 is provided with a cover member 154 that divides the entrance of the recessed space 161 of the receiving member 153 into a plurality of openings and forms a plurality of back side coupling portions 176. As a result, even if the metal receiving member 153 is not provided with a portion that divides the entrance of the recessed space 161 into a plurality of openings, the function of partitioning is performed by the cover member 154. Thereby, the shape of the receiving member 153 can be simplified. In particular, since the cover member 154 is made of synthetic resin, a portion having a complicated shape in the back side coupling portion 176 is formed with the cover member 154 made of synthetic resin, and a portion for locking the coupler 181 is made of metal. The back side coupling portions 176 can be formed satisfactorily.

  Further, in the configuration in which the receiving member is individually installed for each of the four back side coupling portions 176, at least four members to be installed in the coupling region forming portion 152 of the back side structure 102 are required. In the configuration of the pachinko machine 10 provided with the receiving member 153 provided over the connecting portion 176 and the cover member 154 that covers the receiving member 153, the number of members installed in the connecting region forming portion 152 is two. . That is, in a configuration in which three or more back side coupling portions 176 are provided, even if the cover member 154 is provided separately from the back side configuration body 102, the receiving member is individually provided for each of the back side coupling portions 176. The number of members can be reduced as compared with the conventional configuration in which the is installed. Accordingly, it is possible to reduce the number of work steps for forming the back side coupling region 151 in the back side structure 102 as compared with the conventional structure.

  Further, instead of providing the cover member 154 separately from the backside structure 102, a configuration in which the function of the cover member 154 is integrally formed with the backside structure 102 is also conceivable. In this case, the backside structure 102 is also possible. There is a concern that the function of covering the periphery of the receiving member 153 and preventing unauthorized access to the receiving member 153 may deteriorate due to the structure of the mold for molding the mold. On the other hand, by providing the cover member 154 separately from the back-side structure 102, the function of preventing the unauthorized access is enhanced, and as described above, the back-side coupling region is compared with the conventional structure. Reduction in the number of members and the number of work steps in forming 151 can be achieved.

  By forming the partition wall portion 175 on the cover member 154, the arrangement of the corresponding front side coupling portion 142 to the back side coupling portion 176 is guided by the partition wall portion 175, and the arrangement can be performed favorably. Further, according to this configuration, the cover member 154 having a function of partitioning the entrance of the recessed space 161 into a plurality of openings functions as a guide portion, so that the cover member 154 can be multifunctional.

  The receiving member 153 is installed with respect to the coupling region forming part 152 of the back side structure 102 after completion. For example, a configuration in which the receiving member 153 is insert-molded when the back-side structure 102 is formed may be considered, but in this case, the mold becomes complicated, which is not preferable. On the other hand, the occurrence of such inconvenience can be suppressed by adopting a configuration in which the receiving member 153 is installed on the back-side structure 102 after completion.

  Further, a fixing portion of the receiving member 153 with respect to the coupling region forming portion 152 is covered with a cover member 154. As a result, in the configuration in which the receiving member 154 is installed on the back-side structure 102 after completion, it is possible to make it difficult to perform an act of illegally releasing the fixed state of the receiving member 153 with respect to the back-side structure 102. Become. Further, according to this configuration, the cover member 154 having a function of partitioning the entrance of the recessed space 161 into a plurality of openings functions to cover the fixing portion of the receiving member 153 with respect to the coupling region forming portion 152, and thus the cover member Multi-function of 154 is achieved.

  While the fixing member and the adhesive for fixing the cover member 154 to the back side structural body 102 are not provided, the cover member 154 is sandwiched between the front side structural body 101 and the back side structural body 102 and fixed to the installation location. . Further, the cover member 154 is not provided with a fixture or an adhesive for fixing the cover member 154 to the back-side structure 102, while the cover member 154 has the front-side coupling portion 142 and the back-side coupling portion 176 in a coupled state, Fixed to the installation location. As a result, the cover member 154 can be fixed to the installation location while simplifying the configuration of the cover member 154.

  By destroying the connecting part 144, it is possible to separate the front side structural body 101 and the back side structural body 102 while maintaining the coupling state of the coupling parts 142 and 176 using the coupling tool 181. It is possible to leave a trace when separating the front side structure 101 and the back side structure 102 while firmly fixing the tool 181. In this case, the connecting portion 144 is provided for the front side connecting portion 142. For example, assuming a configuration in which the connecting portion 144 is provided with respect to the back side coupling portion 176, the front side structure 101 and the back side structure 102 cannot be separated only by destroying the connecting portion 144. It is assumed that the receiving member 153 needs to be broken. If it does so, isolation | separation operation of the front side structure 101 and the back side structure 102 cannot be performed easily. On the other hand, since the connection part 144 is provided with respect to the front side coupling part 142, the above-described inconvenience does not occur, and the separation operation of the front side structure 101 and the back side structure 102 is easily performed. It becomes possible.

  In addition, the connecting portion 144 is provided for the front side coupling portion 142 and is individually provided for each front side coupling portion 142. Accordingly, for example, in a situation where the cover member 154 is fixed in association with the one set of the front side connecting portion 142 and the back side connecting portion 176 being in a fixed state, the one set of the connecting portions 142 and 176 is set. Even if the connecting part 144 corresponding to the above is broken and the front side structural body 101 and the back side structural body 102 are separated, the fixed state using the coupler 181 is maintained for the pair of coupling parts 142 and 176, Accordingly, the state where the cover member 154 is fixed is maintained. Therefore, the fixed state of the cover member 154 via the coupler 181 can be favorably maintained.

  The cover member 185 includes a receiving plate portion 185, and in a state where the front side structural body 101 and the back side structural body 102 are combined, the frame portion 112 of the front side structural body 101, the peripheral portion of the main control board 91, and the back side structural body 102. The support plate portion 185 holds the receiving plate portion 185. Accordingly, the cover member 185 can be held in a stable state at the installation location without providing a dedicated fixture or the like for the cover member 185.

  In the board box 92 of the main control device 63, a hook portion 111 is provided on the long side portion of the front side structure 101, and a latch receiver 121 is provided on the long side portion of the back side structure 102 so as to correspond to the hook portion 111. The hook portion 111 and the locking receiver 121 are in the locked state, and even if an attempt is made to widen the boundary between the front structure 101 and the back structure 102, it is physically suppressed. . Thereby, it becomes possible to suppress the fraud.

  In this case, a part of the peripheral surface defining the internal space of the substrate box 92 is formed on the inner surface of the frame portion 112 with which the hook portion 111 is integrally formed. For example, a configuration in which the inner wall portions 126 of the pedestal portions 124 and 125 constituting the locking receiver 121 are provided so as to overlap the entire frame portion 112 on the inner space side of the substrate box 92 is considered. If the space is reduced by that amount and an internal space of the same degree as in the above embodiment is to be secured, the substrate box 92 needs to be made larger than in the above embodiment. On the other hand, according to the present configuration, it is possible to suppress the cheating while reducing the size of the board box 92.

  The combination of the hook part 111 and the latching receiver 121 is provided in the long side part which opposes in the board | substrate box 92, respectively, and multiple sets are provided in each long side part. Therefore, it is possible to more firmly suppress the act of trying to widen the boundary between the front side structure 101 and the back side structure 102. Further, in the configuration in which the hook part 111 and the locking receiver 121 are provided in each of the opposing long side parts, there is a concern that the size of the substrate box 92 is increased accordingly. On the other hand, since the inner surface of the frame portion 112 forms part of the peripheral surface defining the internal space of the substrate box 92 in both of the corresponding long side portions, the substrate box 92 can be reduced in size. It becomes possible to plan.

  The locking receiver 121 is provided for the pedestal portions 124 and 125, and the locking portion between the hook portion 111 and the locking receiver 121 is an internal space of the substrate box 92 by the peripheral wall portions 122 and 123 and the inner wall portion 126. Surrounded by the sides and outside the substrate box. Thereby, it becomes difficult to perform the act of trying to release the locked state between the hook part 111 and the lock receiver 121 illegally, and the illegal action can be prevented. In this case, since the inner surface of the frame portion 112 and the inner surface of the inner wall portion 126 constitute a part of the peripheral surface that defines the internal space of the substrate box 92, the hook portion 111 as described above. The board box 92 can be downsized in a configuration that can prevent the act of illegally releasing the locked state between the lock receiver 121 and the lock receiver 121.

  The front end portion of the frame portion 112 overlaps the portion of the base portions 124 and 125 where the insertion opening for the hook portion 111 is formed. When a part of the peripheral surface that defines the internal space of the substrate box 92 is formed by the inner surface of the frame portion 112 as described above, the substrate box 92 is formed between the frame portion 112 and the pedestal portions 124 and 125. It is assumed that a fraudulent jig such as a lead wire is inserted into the internal space of the. On the other hand, since the front end portion of the frame portion 112 overlaps the portion of the pedestal portions 124 and 125 where the insertion portion of the hook portion 111 is formed, the substrate box is inserted between the frame portion 112 and the pedestal portions 124 and 125. It is possible to prevent the act of inserting the fraudulent jig into the internal space 92.

  In particular, by making the projecting dimension of the frame part 112 from the base part 110 the same as the thickness dimension of the main control board 91, the main control is performed in a region where the internal space of the substrate box 92 is defined on the inner surface of the frame part 112. While allowing the peripheral edge of the substrate 91 to be inserted, the entire tip of the frame 112 can be overlaid (abutted) on a portion of the pedestals 124 and 125 where the insertion opening for the hook 111 is formed. It should be noted that by making the projecting dimension of the frame part 112 from the base part 110 larger than the thickness dimension of the main control board 91, the entire front end part of the frame part 112 and the insertion opening of the hook part 111 in the pedestal parts 124 and 125 are provided. It is possible to superimpose with the site where the is formed with a margin.

  In addition, since the boundary between the frame portion 112 and the pedestal portions 124 and 125 is closed from the outside by the peripheral wall portions 122 and 123, an attempt to insert a fraudulent jig into the internal space of the board box 92 through the boundary. It's hard to do.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows. Incidentally, the configuration of the following different embodiment may be applied individually to the configuration in the above embodiment, or may be applied in combination with each other.

  (1) A modification of the main control device is shown in FIGS.

  (1-1) The main controller 230 shown in FIG. 21A includes a board box 231, and the board box 231 has a coupling structure, like the board box 92 of the main controller 63 in the above embodiment. ing. However, one set of coupling portions 232 constituting the coupling structure is provided on both ends of the short side portion 233 of the substrate box 231, and the coupling portions 232 are separated from each other. In this case, the coupling structure includes a receiving member 234 that locks the coupler. The receiving member 234 is made of metal, and is provided over the entire short side portion 233 or substantially the whole. And it is located over both the coupling | bond parts 232 spaced apart.

  Even in this configuration, since the metal receiving member 234 that locks the coupler is provided over the plurality of coupling portions 232, the latching portions are individually provided for the coupling portions 232. Compared with the configuration, the workability in performing the forming operation of the coupling structure is improved. The receiving member 234 is made of metal, and is provided over the entire short side 233. Therefore, it is possible to prevent the receiving member 234 from destroying the short side portion 233 and attempting to illegally access the internal space of the substrate box 231.

  (1-2) The main controller 240 shown in FIG. 21B includes a substrate box 241. The substrate box 241 includes a coupling structure similar to the substrate box 92 of the main controller 63 in the above embodiment. Yes. However, the coupling structure is provided not only on one short side portion of the substrate box 241 but also on both short side portions 242 and 243. In this case, each of the short side portions 242 and 243 has a plurality of connecting portions 244 arranged in parallel. In addition, metal receiving members 245 and 246 are provided for the short side portions 242 and 243, respectively. Each receiving member 245,246 is provided over the whole or substantially the whole in the corresponding short side part 242,243.

  As described above, the coupling structures are provided on the short sides 242 and 243, so that each component of the substrate box 241 can be more firmly fixed, and traces remain when the fixation is released. Increasing the number will facilitate discovery. In addition, since the metal receiving members 245 and 246 are provided over the entire short side portions 242 and 243 facing each other, the short side portions 242 and 243 are broken to break down the substrate box 241. It is possible to prevent the receiving members 245 and 246 from illegally trying to access the internal space of the receiving members 245 and 246.

  In the configuration of FIG. 21 (b), the coupling portion 244 is arranged in parallel to the opposing long side portions, and a metal receiving member is positioned so as to be located over the whole or substantially the entire long side portion. It is good also as a structure which installs. Moreover, it is good also as a structure which installs the connection part 244 only in the opposing long side part, and installs a metal receiving member so that it may be located over the whole or substantially whole of these long side parts.

  (2) It is not an essential configuration that the receiving member 153 has the recessed space 161, and a locking portion 158 is formed on one plate portion, and when the receiving member 153 alone is viewed, The engaging portion 158 may be exposed instead of being accommodated in the space. In this case, although the locking portion 158 is not accommodated in the space, the security is lower than that of the above embodiment, but the configuration of the receiving member 154 can be simplified.

  (3) Although the cover member 154 is made of synthetic resin in the above embodiment, it may be made of metal instead of this. In addition, a dedicated fixing tool for fixing the synthetic resin or metal cover member 154 to the front side coupling region 141 may be provided. Instead, the synthetic resin or metal cover member 154 may be coupled to the front side coupling. The region 141 may be fixed using an adhesive. In this case, although the configuration is more complicated than that of the above embodiment with respect to fixing the cover member 154, the cover member 154 can be held in the front-side coupling region 141 in a stable state.

  (4) Although the receiving member 153 is made of metal in the above embodiment, the receiving member 153 is not limited to metal as long as it has higher strength than the wall portion of the backside structure 102. For example, the receiving member 153 is formed of a material in which a reinforcing agent such as glass fiber is dispersed in a synthetic resin material that forms the back side structure 102 or a synthetic resin material different from the synthetic resin material. Also, the strength may be increased. Further, by forming the receiving member 153 by subjecting a synthetic resin material forming the back side structural body 102 or a synthetic resin material different from that to surface treatment such as plating, the back side structural body 102 You may make it stronger than a wall part.

  (5) The cover member 154 is not provided. Instead, the opening corresponding to the shape of the front side coupling portion 142 and a function as a guide portion for guiding the front side coupling portion 142 are integrated into the receiving member 153. It is good also as a structure. In this case, since the back side coupling region 151 is formed by installing the receiving member 153 in the coupling region forming part 152, the operation of forming the back side coupling region 151 can be simplified and the cover member 154 is not provided. Thus, the number of members can be reduced.

  (6) The receiving member 153 may be insert-molded with respect to the back side structure 102. Even in this case, a single receiving member 153 can be used in the mold for molding the back side structure 102 compared to a configuration in which the receiving member is individually provided corresponding to each back side coupling portion 176. The workability of the work of arranging the receiving member 153 is improved.

  (7) The front-side coupling portion 142 and the back-side coupling portion 176 may be coupled by the breaking screw instead of the coupling tool 181. Here, the breaking screw is a screw whose strength is set low at the connection between the head where the tip of a tool such as a screwdriver can be inserted and the side where the screw groove is formed, and can be tightened further. When a predetermined force is further applied to the head by the tool at a position where it cannot be performed, the connecting portion is cut and the head is separated. That is, the breaking screw cannot be rotated in the loosening direction using the tool after screwing. In the case of this configuration, the receiving member 153 may have a configuration in which screw hole portions for screwing the fracture screws are provided corresponding to the respective back side coupling portions 176.

  Moreover, it is good also as a structure by which the coupling | bonding of the front side coupling | bond part 142 and the back side coupling | bond part 176 is performed with a normal screw instead of a fracture | rupture screw. In this case, after the front side coupling portion 142 and the back side coupling portion 176 are coupled by the normal screw, the head portion of the screw is sealed so that the screw cannot be removed. It becomes impossible or difficult to release the coupling state with the back side coupling portion 176.

However, instead of this, the inner wall portion 126 may not be provided in the surrounding portion, and the locking portion between the hook portion 111 and the locking receiver 121 may be exposed in the internal space of the substrate box 92. In this case, it is easier to access the locking portion between the hook portion 111 and the locking receiver 121 than in the above embodiment, but the inner wall portion 126 can be omitted in the pedestal portions 124 and 125. Therefore, the internal space of the substrate box 92 can be expanded as compared with the above embodiment.

  (13) In the above-described embodiment, the number of box structures forming the substrate box 92 is arbitrary as long as it is plural. As a structure in which the substrate box 92 is formed by combining four or more box structures. Also good. In this case, another box structure may be provided between the main control board 91 and the front side structure 101 so as to block the space between the two, and between the main control board 91 and the back side structure 102. Another box structure may be provided so as to block both spaces.

  (14) In the above embodiment, the hook portion 111 and the locking receiver 121 may be omitted, and the front side structure 101 and the back side structure 102 may be bonded to each other with an adhesive at the long side portion of the substrate box 92.

  (15) The configuration applied to the board box 92 of the main control device 63 in the above embodiment is applied to other control devices such as the sound lamp control device 66, the payout control device 82, the power source and the launch control device 83. Also good.

  (16) In each of the above embodiments, the present invention is applied to the pachinko machine 10 provided with the upper plate 57a and the lower plate 58a as the outer storage unit. Instead, a single outer storage unit is provided. The present invention may be applied to a pachinko machine. Further, by providing the power failure monitoring device separately from the main control device 63, the main control board 91 may be configured to have only the function of the main control circuit 202.

  (17) Other types of pachinko machines different from the above-described embodiments, such as pachinko machines in which an electric accessory is released a predetermined number of times when a game ball enters a specific area of a special device, or games in a specific area of a special device The present invention can also be applied to a pachinko machine that generates a big hit when a ball enters, a pachinko machine equipped with another accessory, an arrangement ball machine, a sparrow ball, and the like.

  Also, a non-ball-type gaming machine, for example, a plurality of reels with a plurality of types of symbols attached in the circumferential direction, starts rotation of the reel by inserting a medal and operating a start lever, and a stop switch is operated. If a specific symbol or a combination of specific symbols is established on the effective line visible from the display window after the reel has stopped after a predetermined time has passed, a privilege such as paying out medals is given to the player The present invention can also be applied to a slot machine.
