[Configuration of controlled system board]
FIG. 14 is a plan view showing the configuration of the controlled system substrate of the pachislot machine according to the present embodiment. FIG. 14A shows the configuration immediately before the final manufacturing process, and FIG. 14B shows the configuration after the final manufacturing process.

  The controlled system board 150 shown in FIG. 14 is an example of the LED board on which the LED and its drive circuit are mounted, among the device boards 130 shown in FIG. As this controlled-system board | substrate 150, the board | substrate arrange | positioned in the position which may be exposed outside, such as LED board 331 which comprises the light emission part 330, for example is assumed.

  As shown in FIG. 14, a connector arrangement pattern 161a for installing a connector and LEDs are installed on one surface of the controlled system substrate 150 (the surface on the side shown in FIG. 14 (hereinafter referred to as the surface)). LED arrangement pattern 161b for performing, circuit element arrangement pattern 161c for arranging circuit elements such as resistors, through-holes 171 formed through the back surface, which is another surface with respect to the front surface, and the like are formed. ing.

  As shown in FIG. 14A, the controlled substrate 150 immediately before the final manufacturing process is in a state where the resist processing for closing the through holes 171 on the front surface and the back surface is not performed. Therefore, in this state, the hole of the through hole 171 is visible in FIG.

  Thereafter, a resist process is performed on the controlled substrate 150 immediately before the final manufacturing process shown in FIG. 14A by applying a resist with a predetermined thickness on the front and back surfaces of the substrate including the through holes 171. . However, at this time, the resist process is performed except for regions where connection processes are left in the future, such as the connector arrangement pattern 161a, the LED arrangement pattern 161b, and the circuit element arrangement pattern 161c.

  FIG. 14B shows the structure of the controlled substrate 150 completed through the resist processing step. In FIG. 14 (b), the front and back surfaces of the controlled substrate 150 are in a state in which the through holes 171 are closed by the resist process in the final manufacturing process described above. This state can be confirmed from the fact that the through hole 171 that was visible in FIG. 14A is not visible in FIG. 14B.

  FIG. 15 is a cross-sectional view of a principal part showing a manufacturing process of the controlled substrate shown in FIG. FIG. 15 particularly shows a cross-sectional structure taken along line CC of the controlled system substrate 150 of FIG. 15A shows a cross-sectional structure of the controlled substrate 150 immediately before the final manufacturing process shown in FIG. 14A, and FIG. 15B shows a state after the final manufacturing process shown in FIG. 14B. 2 shows a cross-sectional structure of the controlled system substrate 150.

  As shown in FIG. 15A, in the controlled substrate 150 immediately before the final manufacturing process, an LED arrangement pattern 161b or the like is formed on the front surface of the base material 153, for example, and a through-hole penetrating the front and back surfaces of the substrate. 171 is formed.

  The structure of the controlled system substrate 150 in FIG. 15A can be generated by a known manufacturing process. For example, a base material 153 made of a copper clad laminate having copper foil formed on both sides is first cut into a predetermined shape, and then a hole 172 for a through hole 171 or an electronic component is placed at a predetermined position according to a circuit design. Drill holes for mounting holes. Subsequently, for example, copper plating is applied to the inside of the hole 172 or the electronic component mounting hole to form a through hole 171 having a plated layer 173 or a component mounting hole.

  Next, a pattern forming process for forming patterns such as wiring patterns and component mounting patterns on both the front and back surfaces is performed. For example, an etching resist is applied to both sides of the holed portion, and after exposure, unnecessary portions other than the pattern are removed to leave a pattern forming resist. Further, the copper foil other than the pattern is removed by an etching process, and the remaining resist is removed.

  The controlled substrate 150 (see FIG. 15A) obtained through the above manufacturing process is subjected to resist processing in the final manufacturing process. In the final manufacturing process, a resist is applied to both the front and back surfaces of the controlled substrate 150 shown in FIG. The controlled substrate 150 having the structure shown in FIG. 15B is completed by resist processing in this final manufacturing process. As shown in FIG. 15B, the completed controlled substrate 150 has resist layers 181 and 182 formed on both the front and back surfaces, and the holes 172 of the through holes 171 are formed on the surface by the resist layer 181 and on the back surface by the resist layer. The structure is closed by 182. That is, the resist layers 181 and 182 that cover the through holes 171 in an insulating manner form a contact prevention layer.

  14 and 15 exemplify a structure in which a through hole 171 is provided in one insulating substrate as the base material 153 and is blocked by resist layers 181 and 182 as contact prevention layers. The present invention is not limited to this. For example, in a laminated substrate in which a plurality of insulating substrates are stacked and a conductive pattern of an arbitrary layer of each insulating substrate is conducted by vias, the vias on both the front and back surfaces are the same as the through holes 171. It is good also as a structure which closes this hole by resist application.

  14 and 15, the controlled substrate 150 for processing the through hole 171 and the via hole, the LED substrate 331 of the device light emitting unit 330, the dot display 100, the reel upper display 101, the reel Although the example of the LED board corresponding to each of the illuminator 102, the reel effect display 103, and the side effect display 104 has been given, in the present invention, in addition to this, the information display for the sound board and the reel lower display 105 is targeted. General boards corresponding to each of a plurality of devices 130 that are production execution means, such as a display control board equipped with a control circuit, or bet buttons 11 and stop buttons 7L, 7C, 7R related to the progress of the game are attached respectively. A switch board (not shown) or the like to be processed can be the target of the above processing.

[Responding to Goto acts]
As a go-to action for the controlled system board 150, for example, an external member provided outside the front door 2 is forcibly taken out to expose the controlled system board 150, or a speaker of the front door 2 is used. Use the 9L and 9R mounting surface gaps, the gaps in the exterior members that cover the outside of the LEDs, etc. to penetrate the device board 130, such as the LED board or audio board, into the place where the special instrument such as a cable is inserted. Insert the conductor part at the tip, that is, the conductor part from which the insulation coating has been peeled, into the hole of the hole 171 (or via), or insert the conductor part at the tip of the special instrument into the hole of the through hole 171. An illegal act such as sending an illegal signal from a communication device (information processing apparatus) connected to the other end of the special instrument is performed.

  In the controlled substrate 150 according to the present embodiment, the through hole 171 (or via) is blocked on both the front and back sides by the resist against such an illegal act (got action). The conductor portion at the tip of the special instrument cannot enter the hole, and electrical conduction through the plating layer 173 that is the conductor layer in the hole of the through hole 171 can be prevented. Therefore, it is possible to prevent power interruption due to a short circuit of the circuit through the through hole 171 and transmission of an unauthorized signal from a communication device, and it is possible to prevent an illegal act.

  As described above, in the present embodiment, through the controlled system substrate 150, for example, the device substrate 130 that may be exposed to the outside, among the device substrates 130 for production such as LED substrates and audio substrates, through holes are provided. The contact prevention layer 171 or the via hole is closed with a resist.

  According to this structure, a third party who performs fraudulently removes the external member of the pachislot machine 1 to expose the controlled system substrate 150, so that the conductor portion at the tip of the illegal special instrument is placed on the substrate. Even if it can penetrate to the position, the through hole or via is blocked by the contact prevention layer so that the conductor part cannot contact, so the tip of the special instrument is in the hole of the through hole or via. It becomes impossible to transmit an illegal signal that may cause the circuit to be short-circuited and a communication device connected to the other end of the special device to disrupt the production. Therefore, by mounting the controlled system board 150 according to the present embodiment, it is possible to reliably prevent an illegal act (power supply gotten) that hinders the operation related to the effect due to the use of the special instrument.

  In the present embodiment, depending on the type of pachislot machine 1, as a controlled system board 150 having a structure in which a through hole 171 or a via hole is closed with a resist, a board on which a graphic module is mounted, a board on which a liquid crystal inverter is mounted, etc. Good for.

[Control system board configuration]
FIG. 16 is a fragmentary cross-sectional view showing the manufacturing process of the control system substrate for the pachislot machine in the present embodiment. As the control system board 760, a board such as the main board 710, the sub board 720, and the sub relay board 750 shown in FIG. 13 is assumed. FIG. 16 particularly illustrates the sub relay board 750.

  Since these control system boards 760 have a function of issuing a control command or the like for the controlled system board 150 described above, more strict prevention measures against a short circuit due to goto operation by a special instrument, sending of illegal signals, etc. are desired. . Therefore, with respect to the control system substrate 760, the strength of the structure that closes the through holes and via holes is increased.

  In FIG. 16A, a through hole 771 is formed in the control system substrate 760 obtained in this step. The through hole 771 is formed by forming a plating layer 773 such as copper plating on the inner peripheral surface of the hole 770 formed through the base 753. Further, on the front and back surfaces of the control system board 760, a region pattern for electronic parts such as connectors, ICs, resistors, etc. (not shown), wiring patterns for electrically connecting the electronic parts, and the like are formed. .

  The manufacturing process of the control system substrate 760 having the structure shown in FIG. 16A in the above process then proceeds to the resin filling process. In the resin filling step, as shown in FIG. 16B, a resin member 775 is filled in the through hole 771 of the control system substrate 760 shown in FIG.

  The manufacturing process of the control system substrate 760 having the structure shown in FIG. 16B in the resin filling process then proceeds to the final process. In the final step, as shown in FIG. 16 (c), the base material is closed so as to block the entire region (exposed portion) facing the front and back surfaces of the through hole 771 sealed with resin in the form shown in FIG. 16 (b). A lid plating process is performed on both the front and back surfaces of 753 to form a lid plating layer 777. After the lid plating process, a resist process for applying a resist with a predetermined thickness on the front and back surfaces of the substrate including the lid plating layer 777 is further performed. In the resist processing, resist coating is not performed on regions such as element region patterns where connection processes remain in the future.

  By the resist process, a control system substrate 760 having a structure shown in FIG. 16C is completed. As shown in FIG. 16C, the completed control system substrate 760 has resist layers 781 and 782 formed on both front and back surfaces, and the holes of the through holes 171 are filled with a resin member 775 and covered with a lid plating layer 775. After plating, the structure is such that the back surface and the back surface are closed by resist layers 181 and 182, respectively. That is, the control system substrate 760 according to the present embodiment includes a resin member 775 embedded in the through hole 771, a lid plating layer 777 that closes the exposed portion of the resin member 775 on the substrate surface, and the lid plating layer 777. The contact prevention layer composed of resist layers 781 and 782 applied so as to insulate the through hole 771 from above is formed.

  Note that FIG. 16 illustrates a structure in which a through hole 771 is provided in one insulating substrate, which is a base material 753, and resin filling, lid plating, and resist coating are performed. For example, in a laminated substrate in which a plurality of insulating substrates are laminated (four to eight layers) and a conductive pattern of an arbitrary layer of each insulating substrate is made conductive by vias, the vias are formed on both front and back surfaces like the through hole 171. A structure may be adopted in which the contact prevention layer is formed by filling a hole with resin, performing lid plating, and applying a resist.

[Responding to Goto acts]
Regarding fraudulent acts targeted at the control system board 760, for example, the main board 710 has a function of sending an execution command of an effect according to the progress of the game to the sub board 720. It is conceivable that the tip of a special instrument is inserted into the through-hole 771 or via of the circuit to be operated to work.

  On the other hand, in the present embodiment, the control system substrate 760 has a structure in which the through hole 771 or the via is filled with a resin and covered with a resist after being subjected to lid plating. As a result, the control system substrate 760 blocks the through hole 771 or the via as compared with the controlled system substrate 150 (see FIG. 15B) whose surface is simply covered with the resist while leaving the through hole or via hole. The surface strength of the contact prevention layer, that is, the laminated portion of the resin member 775, the lid plating layer 777, and the resist layers 781 and 782 is greatly increased. Therefore, the control system substrate 760 can more securely prevent the tip of the unauthorized device from entering the through hole 771 or the via than the controlled system substrate 150.

  Note that the control system board 760 has a control function for the controlled system board 150 under its control and has a high tendency to increase the damage when the goto action is performed. Regardless of whether or not there is a property, it is desirable to form a contact prevention layer composed of the above-described resin member 775 for preventing fraud, the lid plating layer 777, and the resist layers 781 and 782.

  Although the embodiment has been described above, the present invention is not limited to this.
