Description

The present invention relates to a game machine board unit that includes a control board and a board case that houses the control board, and is mounted on the game machine.

The control board for the game machine is housed in a board case that is difficult to open from the viewpoint of fraud prevention, and is mounted on the game machine in a unitized state. Further, on the control board, at least different identification information is attached to the printed circuit board for each manufacturer. Here, in some conventional control boards, the identification information display unit to which the identification information is attached can be separated from the printed circuit board main body via an easy break line. This is a configuration for sharing the printed circuit board with a plurality of manufacturers in order to reduce costs (see Patent Document 1). That is, as in Patent Document 1, at the stage of manufacturing a printed circuit board, a plurality of identification information display units with identification information of different manufacturers are arranged, and a manufacturer of a game machine that actually mounts the substrate unit. The identification information display unit is left, and the identification information display unit of other manufacturers is configured to be separated by an easy break line.

Japanese Unexamined Patent Publication No. 2006-068112

As described above, in the control board configured to dispose a plurality of identification information display units on the printed circuit board and separate the parts other than the necessary identification information display units, the unnecessary identification information display units are easily broken. Although it can be easily separated, since the necessary identification information display unit is used in a state where it is continuous with the printed circuit board body via the easy break line, the easy break line is caused by vibration or impact during transportation or use of the game machine. Is broken, and there is a concern that the necessary identification information display unit will be separated. Even if the necessary identification information display unit is separated, there is no problem in the operation of the control board, but it cannot be used in the amusement park because it is confused with an illegally modified product. Under such circumstances, it is proposed to widen the interval of the penetrating portion of the easy breaking line to make it difficult to break. However, if the easy break line is hard to break, when the identification information display unit is separated, the portion other than the easy break line is easily damaged, and the defect rate increases. Further, the more difficult it is for the easy break line to break, the greater the labor and cost of using the instrument when disconnecting the identification information display unit.

The present invention has been made in view of the present situation, and the identification information display unit is located on a board unit for a game machine in which the identification information display unit is continuous with the printed circuit board main body via an easy break line, and the identification information display unit is formed by breaking the easy break line. It is an object of the present invention to provide a structure in which easy breaking lines are not easily broken by vibration or impact.

The first invention of the present invention is a board unit for a gaming machine, which includes a control board in which electronic components are mounted on a printed circuit board and a board case for accommodating the control board, and is mounted on the game machine. On the outer peripheral portion of the substrate, one identification information display unit, which is separably continuous with the printed circuit board main body via an easy break line, and identification information different from the identification information display unit are attached. The other identification information display unit is provided with a notch portion separated from the printed circuit board main body by an easy break line, and the easy break line between the printed circuit board main body and the one identification information display unit. Has a perforated shape formed by forming through portions penetrating the printed circuit board at intervals along the easy break line, and a part or all of the through portions is filled with a solder alloy. It is a board unit for a game machine characterized by being

Solder alloys are low melting point metals that exhibit creep characteristics and stress relaxation properties at room temperature, and generate strong stress against momentary loads, but the stress decreases when a continuous load is applied. Therefore, it can be easily deformed. Therefore, in such a configuration, when a strong load is temporarily applied to the easily broken line of the printed circuit board due to vibration or impact during transportation or use, the solder alloy filled in the penetrating portion is loaded. Since a strong stress is generated against the solder, it is possible to prevent the breakage line from breaking due to vibration, impact, or the like, as compared with the conventional configuration. On the other hand, in such a configuration, when the printed circuit board is bent at the easy breaking line and a strong load is continuously applied to the easy breaking line, the stress of the solder alloy decreases, so that the easy breaking line penetrates. The stress can be concentrated on a part other than the part, and the printed circuit board can be broken at the easy breaking line.

As described above, in the present invention, the easy breaking line is hard to break by vibration, impact, etc., and easily broken by bending, so that the unnecessary identification information display unit can be easily separated and the necessary identification is required. The information display unit has an advantage that it is difficult to separate due to vibration or impact. Further, in the present invention, the penetration portion is filled with the solder alloy because it can be performed by using the equipment used for soldering in the step of soldering the electronic component to the printed circuit board. There is an advantage that it can be realized with labor and cost.

In the first invention of the present invention, the inner surface of the penetration portion filled with the solder alloy is coated with the same conductive metal as the circuit wiring of the printed circuit board, and the conductive metal covering the inner surface of the penetration portion. Is proposed not to constitute the circuit wiring of the printed circuit board.

According to such a configuration, the solder alloy filled in the penetrating portion can be strongly bonded to the printed circuit board. Further, since the coating of the inner surface of the penetrating portion can be performed at the same time as the formation of the circuit wiring in the step of forming the circuit wiring on the printed circuit board, it can be realized with less labor and cost. Further, although a stronger load is likely to be applied to the penetrating portion of the easily broken line as compared with the printed circuit board main body, the conductive metal covering the inner surface of the penetrating portion does not constitute the circuit wiring, so even if the circuit is damaged, the circuit of the printed circuit board There is no problem with the wiring.

Further, in the first invention of the present invention, a part of the one identification information display unit is coated with the same conductive metal as the circuit wiring of the printed circuit board, and the conductivity covering the one identification information display unit. It is proposed that the metal does not constitute the circuit wiring of the printed circuit board.

According to such a configuration, since the identification information display unit is reinforced by the conductive metal covering the identification information display unit, it is possible to prevent the identification information display unit from being deformed by vibration or impact from the outside. Since the coating of the identification information display unit can be performed at the same time as the circuit wiring is formed in the process of forming the circuit wiring on the printed circuit board, it can be realized with less labor and cost. Further, since the coating of the identification information display unit does not constitute the circuit wiring, there is no problem in the circuit wiring of the printed circuit board even if it is damaged.

Further, in the first invention of the present invention, the one identification information display unit is continuous with the printed circuit board main body only through a straight easy break line provided on one side edge of the identification information display unit. The one identification information display unit is not supported by the substrate case, and the substrate case is connected to the printed circuit board main body along the straight line and / or the identification information display unit. It is proposed to provide ribs that abut and support the printed circuit board body.

When both the printed circuit board body and the identification information display part are supported by the board case, when different loads are applied to the support parts on both sides due to external vibration or impact, a relatively strong load is applied to the easy break line between the two. However, in such a configuration, the board case does not support the identification information display side, so that the board case may be damaged due to the vibration of the identification information display unit and the contact with the board case. When vibration or impact is applied from the outside, the load applied to the easy breaking line can be reduced, and the vibrated identification information display unit does not come into contact with the substrate case and be damaged. Further, in such a configuration, since the printed circuit board main body is supported along the easy break line and the identification information display unit, the vibration of the identification information display unit is minimized even if the identification information display unit is not directly supported. Therefore, the load applied to the easy breaking line can be minimized.

The second invention of the present invention is a board unit for a game machine, which includes a control board obtained by mounting electronic components on a printed circuit board and a transparent board case for accommodating the control board, and is mounted on the game machine. On the outer peripheral portion of the printed circuit board, one identification information display unit, which is separably continuous with the printed circuit board main body via an easy break line, and identification information different from the identification information display unit are attached. The other identification information display unit is provided with a U-shaped or L-shaped notch that is separated from the printed circuit board main body, and is a region of the substrate case that accommodates the control substrate. Has a gap in the area corresponding to the other identification information display unit, a socket is mounted on one surface of the printed circuit board in the vicinity of the notch portion, and a control chip is attached to the socket. The board unit for a gaming machine is characterized in that the socket and / or the control chip can be visually recognized from the back side of the one side of the printed circuit board through the notch.

In such a configuration, the control chip or socket can be visually recognized from the back side (diagonal direction), and the visibility of the control chip or socket is improved. Therefore, the control chip or socket is arranged between the control chip and the socket. It becomes easier to find illegal parts. Here, the cutout portion formed in the printed circuit board is in the conventional control board provided with a plurality of identification information display units, and is inevitably formed after the unnecessary identification information display unit is separated. In the present invention, in order to improve the visibility of the control chip and the socket, it is not necessary to form a new notch on the printed circuit board. Further, the internal space of the existing board case for accommodating the control board is designed to accommodate all the identification information display units so that the control board can be accommodated regardless of which identification information display unit is left. Even in the internal space of the existing substrate case, the region corresponding to the separated identification information display portion, that is, the region where the notch portion is formed is a gap. Therefore, the present invention has an advantage that it can be realized without expanding the internal space of the existing substrate case.

In the second invention of the present invention, the one identification information display unit is arranged so as to be adjacent to the notch portion, and the socket is located near the boundary between the one identification information display unit and the notch portion. The socket and / or the control chip is provided from the back side of the one side of the printed circuit board through a notch formed when the one identification information display unit is separated from the printed circuit board main body. It is proposed that it is visible.

In such a configuration, regardless of which of the plurality of identification information display units previously arranged on the printed circuit board is left, the socket is formed from the notch formed after the other identification information display units are separated. And / or the control chip becomes visible. That is, in such a configuration, the visibility of the control chip and the socket can be improved regardless of which identification information display unit is left, so that the convenience is improved.

Further, in the second invention of the present invention, an opaque sealing member configured to leave a trace when the substrate case is opened is disposed in the vicinity of the notch, and the substrate case is viewed from the outside. It is also proposed that the sealing member be visible through the notch.

Generally, the sealing member is arranged in the vicinity of the control board, and the printed circuit board becomes an obstacle and is difficult to see from only one direction. Therefore, traces are observed from various angles of the board unit for the gaming machine. We are checking for the presence of. On the other hand, in such a configuration, the printed circuit board does not interfere with the confirmation of the trace of the sealing member because the sealing member can be visually recognized through the notch, so that the presence or absence of the trace of the sealing member can be confirmed more easily than in the conventional configuration.

Embodiments of the present invention will be described with reference to the following examples. In the following examples, the sealing member according to the present invention corresponds to the lock member 12 and the sealing seal 44.

FIG. 1 is a slot machine 1 including a board unit 6 for a game machine (hereinafter, also referred to as a board unit) of this embodiment. As shown in FIG. 1, the housing 2 of the slot machine 1 is open to the front and is covered by the front door 3 from the front. Further, three reels 4 are provided in the central portion of the housing 2, and a visual recognition window 5 for visually recognizing the reel 4 is provided in the central portion of the front door 3. Then, the substrate unit 6 of this embodiment is mounted inside the housing 2 above the reel 4.

The substrate unit 6 of this embodiment accommodates the control substrate 8 in the substrate case 7. As shown in FIGS. 2 and 3, the substrate unit 6 includes a pair of mounting brackets 9a and 9b made of bent metal pieces, and the mounting brackets 9a and 9b are screwed 14 on the back plate 2a covering the back surface side of the housing 2. The board case 7 which is fixed by the above and houses the control board 8 is attached to the mounting brackets 9a and 9b. Here, the left side mounting bracket 9a and the board case 7 are fastened with screws 14. On the other hand, the mounting bracket 9b on the right side is locked to the substrate case 7 by inserting the lock member 12 described later into the through hole 9c while being inserted into the slit 38 (see FIG. 7) of the substrate case 7. Further, since the screws 14 for fixing the mounting brackets 9a and 9b to the back plate 2a are covered by the board case 7, the mounting brackets 9a and 9b cannot be removed from the back plate 2a when the board case 7 is mounted. It becomes. In the following, the front side in FIG. 2 is the front side of the board unit 6, the board case 7, and the control board 8, and the top, bottom, left, and right in FIG. 2 are the board unit 6, the board case 7, and the control board 8. It will be explained as top, bottom, left and right of.

The control board 8 constituting the board unit 6 is a main control board that comprehensively controls the game of the slot machine 1. As shown in FIG. 4, such a control board 8 is formed by mounting electronic components such as a socket 17 and connectors 16a and 16b on the front side of a horizontally long rectangular printed circuit board 15, and the socket 17 is controlled. The chip 18 is detachably attached. Although not shown in FIG. 4, a circuit wiring made of copper foil is arranged on the front side of the printed circuit board 15 and is covered with an insulating coating (solder resist). Although not shown, a large number of electronic components (capacitors, resistors, etc.) are mounted on the front side of the printed circuit board 15 in addition to the socket 17 and the connectors 16a and 16b. Through holes for mounting each electronic component are also formed. Further, a screw through hole 22 for fixing the printed circuit board 15 to the substrate case 7 is formed in the central portion of the printed circuit board 15.

As shown in FIG. 4, a rectangular identification information display unit 19b with identification information attached to the front side is arranged on the right edge of the printed circuit board 15 of the control board 8 of this embodiment. The identification information is composed of the manufacturer name (EFG company) of the slot machine 1 and the model number (H-5678), and is printed by silk printing. The identification information display unit 19b and the printed circuit board main body 20 are completely separated by a slit 29 at the upper and lower boundaries, and are continuous at the left and right boundaries via a linear easy break line 27 formed in a perforation pattern. The identification information display unit 19b can be separated from the printed circuit board main body 20 by pinching and bending the identification information display unit 19b with a finger or a tool to break the easy break line 27. Further, on the right edge of the printed circuit board 15, a U-shaped notch 28 is arranged so as to be vertically adjacent to the identification information display unit 19b. The cutout portion 28 is formed by separating another identification information display portion 19a arranged on the printed circuit board 15 from the printed circuit board main body 20. More specifically, at the time of manufacturing the printed circuit board 15, as shown in FIG. 5A, two identification information display units 19a and 19b are arranged adjacent to each other on the right side edge of the printed circuit board 15 on the front side. To. The two identification information display units 19a and 19b have the same shape and are separably continuous with the printed circuit board main body 20 via the easy break line 27, but different identification information is present on the front side thereof. It is attached. The two identification information display units 19a and 19b are configured to use the printed circuit board 15 for the slot machines of the two game machine manufacturers. That is, when used in a slot machine manufactured by EFG, as shown in FIG. 5B, the identification information display unit 19a to which the company name and model number of ABC are attached as identification information is separated by an easy break line 27. , EFG company name and model number are used as identification information with the identification information display unit 19b left. On the other hand, when used in a slot machine manufactured by ABC, as shown in FIG. 5C, the identification information display unit 19b to which the company name and model number of EFG are attached as identification information is separated by an easy break line 27. , ABC company name and model number are used as identification information with the identification information display unit 19a left. Therefore, in the control board 8 constituting the board unit 6 of the present embodiment, one identification information display unit 19a, 19b is left in a state of being connected to the printed circuit board main body 20, and the remaining identification information display units 19a, 19b are left. A portion separated from the printed circuit board main body 20 is a U-shaped notch 28. The control board 8 according to the present embodiment is shown in which the identification information display unit 19b with the company name and model number of EFG is left on the printed circuit board 15.

As shown in FIGS. 6 and 7, the substrate case 7 is formed by assembling a rectangular box-shaped cover member 10 with an open back side and a rectangular box-shaped base member 11 with an open front side with a fixing screw 13. The control board 8 is housed in the internal space 32 formed when the cover member 10 and the base member 11 are assembled. Specifically, the cover member 10 and the base member 11 have a horizontally long rectangular shape that is one size larger than the control board 8 when viewed from the front, and the internal space 32 of the board case 7 can accommodate the entire control board 8. It has a rectangular parallelepiped shape. Here, the internal space 32 of the substrate case 7 has a size capable of accommodating the control substrate 8 having a size before the identification information display units 19a and 19b are separated from the printed circuit board main body 20, and any of the identifications can be identified. The control board 8 including the information display units 19a and 19b can also be housed in the board case 7. Therefore, in the internal space 32 of the board case 7 that accommodates the control board 8 from which the identification information display unit 19a is separated, there is no region corresponding to the separated identification information display unit 19a, that is, a region corresponding to the notch 28. It is an unaccommodated void.

The cover member 10 and the base member 11 are molded products made of transparent resin, and are configured so that the inside of the substrate case 7 can be visually recognized through the cover member 10 and the base member 11. As shown in FIGS. 3 and 6, a connector opening 23 is formed in the cover member 10, and when the control board 8 is housed in the board case 7, only the connectors 16a and 16b mounted on the control board 8 are available. The portion of the control board 8 excluding the connectors 16a and 16 that is exposed to the outside from the connector opening 23 is covered with the cover member 10 and the base member 11.

As shown in FIGS. 6 and 7, columnar ribs 30a and E-shaped ribs 30b are formed on the inner side surface of the cover member 10 so as to project to the back surface side and abut on the front surface side of the outer peripheral portion of the printed circuit board 15. Further, as shown in FIGS. 6 and 7, bosses 35 and 37 that come into contact with the central portion of the printed circuit board 15 are formed on the inner side surfaces of the cover member 10 and the base member 11. The substrate case 7 is configured to stably support the housed control substrate 8 by bringing these ribs 30a, 30b and bosses 35, 37 into contact with the printed circuit board 15 in the internal space 32.

In order to prevent fraudulent acts on the control board 8, the cover member 10 and the base member 11 are difficult to separate from each other with the control board 8 housed in the board case 7. Specifically, as shown in FIGS. 6 and 7, the right side portion of the cover member 10 with the engaging claw 34 of the left side wall 31b of the base member 11 engaged with the engaging hole 24 of the left side wall 21b. The right side walls 21a and 31a of both members 10 and 11 are engaged by the sealing structure 40 of the above, and both members 10 and 11 are fastened to each other by a fixing screw 13 from the back surface side. Further, as shown in FIGS. 3, 6 and 7, in this embodiment, the seal seal 44 is attached so as to be wound around the right side portion of the substrate case 7 in a state where the cover member 10 and the base member 11 are engaged with each other. To.

As shown in FIGS. 3, 6 and 7, the sealing structure 40 is formed by inserting the lock member 12 into the through holes 25 and 39 formed in the right side walls 21a and 31a of the cover member 10 and the base member 11. The right side walls 21a and 31a of the members 10 and 11 are engaged with each other. Four sets of sealing structures 40 are provided on the right side of the substrate case 7, and the cover member 10 and the right side walls 21a and 31a of the base member 11 can be engaged with each other by an arbitrary sealing structure 40. The lock member 12 is an opaque resin member formed by projecting a locking pin 42 into a rectangular plate-shaped operating portion 41. A lock member holding frame 36 is formed on the right side wall 31a of the base member 11, and the lock member 12 is held by the lock member holding frame 36 with the locking pin 42 facing inward. Then, as shown in FIG. 8, when the operation portion 41 of the lock member 12 is pushed inward, the locking pin 42 penetrates the cover member 10 and the right side walls 21a and 31a of the base member 11, and both members 10 and 11 The right side walls 21a and 31a of the above are engaged by the locking pin 42, and the substrate case 7 is sealed by the sealing structure 40.

When the substrate case 7 is sealed by the sealing structure 40, the substrate case 7 cannot be opened unless an opening is formed in the cover member 10 or the base member 11. It is difficult to pull out the locking pin 42 on which the barb is formed from the right side walls 21a and 31a of both members 10 and 11, and a cutting tool is inserted inside the board case 7 to engage the inside of the board case 7. This is because the engagement between the cover member 10 and the base member 11 cannot be released unless the stop pin 42 is cut. Therefore, in this embodiment, as shown in FIG. 6, a rectangular thin-walled portion 26 capable of easily forming an opening for inserting a cutting tool in the front side portion of each sealing structure 40 of the cover member 10. Is provided.

Further, the sealing sticker 44 is an opaque ribbon-shaped adhesive sheet on which a characteristic pattern is printed, and is attached so as to be wound around the right side portion of the substrate case 7 as shown in FIGS. 3 and 8. At this time, the seal seal 44 is attached so as to straddle the boundary between the cover member 10 and the base member 11, and is also attached so as to cover the thin portion 26 of the cover member 10. Therefore, in the present embodiment, the substrate case 7 cannot be opened without damaging the seal seal 44, and the thin-walled portion 26 cannot be opened unless the seal seal 44 is broken. Will be done. The seal sticker 44 is firmly adhered to the substrate case 7 and is easily damaged, so that it is difficult to peel off and reattach the seal seal 44 without damaging it. ..

As described above, in the present embodiment, the substrate case 7 is sealed by the sealing structure 40 and the sealing seal 44, and when the substrate case 7 is opened, the locking pin 42 of the lock member 12 is cut or the locking pin 42 is cut. You have to break the seal 44. That is, in this embodiment, when the substrate case 7 is opened, a trace of opening remains on the locking pin 42 and the sealing seal 44. Therefore, in this embodiment, by checking whether the locking pin 42 is cut and whether the sealing sticker 44 is correctly attached, it is possible to check whether the substrate case 7 is opened without permission. You can check it.

The main components of the second invention of the present case will be described below.
As described above, in the substrate unit 6 of this embodiment, since the cover member 10 and the base member 11 constituting the substrate case 7 are made of transparent resin, the substrate case 7 is passed through to the internal control substrate 8. It is possible to check from the outside whether or not there is any fraudulent activity. Here, one of the most notable fraudulent acts is the act of mounting a fraudulent component between the control chip 18 and the socket 17. As described below, the present embodiment is configured so that the presence or absence of such fraudulent activity can be easily confirmed as compared with the conventional configuration.

In this embodiment, as shown in FIG. 4, on the front side of the printed circuit board 15, the socket 17 is mounted in the vicinity of the notch 28 on the right edge, and the control chip 18 is mounted on the socket 17. There is. Specifically, the socket 17 and the control chip 18 are arranged so that the identification information display unit 19b and the notch portion 28 are adjacent to each other on the left side of the vertically adjacent boundary portion. As described above, in this embodiment, the socket 17 and the control chip 18 are arranged so as to be adjacent to the notch 28, and the region of the substrate case 7 corresponding to the notch 28 is a gap. Therefore, in the board unit 6 of this embodiment, the socket 17 and the control chip 18 can be visually recognized from the back side of the control board 8 through the notch 28.

More specifically, as shown in FIG. 9A, in the case of the substrate unit 6a in which the notch 28 is not formed in the vicinity of the socket 17 and the control chip 18, the substrate unit 6a is opaque as shown in FIG. 10A. Since the printed circuit board 15 is an obstacle, the socket 17 and the control chip 18 can be seen only from the front side (upper side in the drawing) of the board unit 6a. On the other hand, as shown in FIG. 9B, in this embodiment, the notch 28 is formed in the vicinity of the socket 17 and the control chip 18, so that as shown in FIG. 10B, From the back side (lower part in the drawing) of the substrate unit 6, the socket 17, the control chip 18, or a region around the socket 17 can be visually recognized through the notch 28.

As described above, in this embodiment, by bringing the socket 17 and the control chip 18 close to the notch 28, the socket 17 and the control chip 18 can be visually recognized from the back side (oblique back side) of the printed circuit board 15. Therefore, the visibility of the socket 17 and the control chip 18 can be improved as compared with the conventional configuration. Therefore, in this embodiment, it becomes easier to find an illegal component arranged between the socket 17 and the control chip 18 as compared with the conventional configuration. Here, the notch 28 formed in the printed circuit board 15 is in the printed circuit board 15 including the plurality of identification information display units 19a and 19b, and after the unnecessary identification information display unit 19a is separated from the printed circuit board main body 20. It is inevitably formed. Therefore, in this embodiment, it is not necessary to newly form the notch portion on the printed circuit board 15 for improving the visibility of the control chip 18 and the socket 17. Further, the substrate case 7 is designed in a shape capable of accommodating all the identification information display units 19a and 19b so that the control board 8 can be accommodated even if any of the identification information display units 19a and 19b are left. is there. Therefore, in the internal space 32 of the substrate case 7, the region corresponding to the separated identification information display portion 19a, that is, the region where the notch portion 28 is formed is inevitably a gap. Therefore, in this embodiment, it is not necessary to expand the internal space 32 of the substrate case 7 in order to improve the visibility of the control chip 18 and the socket 17.

Further, in this embodiment, the socket 17 and the control chip 18 are arranged so as to be adjacent to the identification information display unit 19b left without separation (see FIG. 4). Therefore, the substrate unit 6 of the present embodiment has a configuration in which the printed circuit board 15 leaves the separated identification information display unit 19a and the remaining identification information display unit 19b is separated (see FIG. 5C). However, the socket 17 and the control chip 18 can be visually recognized from the back side of the printed circuit board 15 through the notch 28 formed after the other identification information display unit 19b is separated. That is, it is said that the control board 8 according to the present embodiment has improved visibility of the control chip 18 and the socket 17 as compared with the conventional configuration, regardless of which of the identification information display units 19a and 19b is left. There are advantages.

Further, as described above, in the substrate unit 6 of the present embodiment, since the locking pin 42 and the sealing seal 44 are configured to leave a trace when the substrate case 7 is opened, the locking pin 42 and the sealing seal 44 By checking for the presence or absence of traces, it can be confirmed whether or not the substrate case 7 has been opened without permission. Here, in this embodiment, since the locking pin 42 and the sealing sticker 44 are arranged on the right side of the cutout portion 28 of the printed circuit board 15, the locking pin 42 and the sealing sticker 44 are arranged as compared with the conventional configuration. The presence or absence of traces can be easily confirmed.

More specifically, as shown in FIG. 9A, in the case of the substrate unit 6a in which the notch 28 is not formed in the vicinity of the locking pin 42 and the sealing seal 44, as shown in FIG. 11A, The printed circuit board 15, the locking pin 42 on the front side, the sealing sticker 44, and the like are in the way, and the locking pin 42 and the sealing sticker 44 on the back side are difficult to see from the front side (upper part in the drawing). .. Therefore, in such a configuration, the locking pin 42 and the sealing seal 44 on the back side must be visually recognized from the back side (lower part in the drawing) of the substrate unit 6a. However, since the back side of the board unit 6a cannot be visually recognized when it is mounted on the slot machine 1, the board unit 6a must be removed from the housing 2 of the slot machine 1 in order to visually recognize the board unit 6a from the back side. , It takes a lot of time to confirm. On the other hand, as shown in FIG. 9B, in this embodiment, the notch 28 is formed in the vicinity of the locking pin 42 and the sealing seal 44, and therefore, as shown in FIG. 11B. From the front side (lower part in the drawing) of the substrate unit 6, the locking pin 42 and the sealing seal 44 on the back side can be visually recognized through the notch 28. Therefore, in this embodiment, the presence or absence of opening traces can be easily confirmed for the locking pins 42 and the sealing seal 44 on both the front and back sides without removing the board unit 6 from the housing 2 of the slot machine 1.

Further, in the case of the substrate unit 6a in which the notch 28 is not formed in the vicinity of the locking pin 42 and the sealing seal 44, as shown in FIG. 11A, the locking pin 42 on the front side (upper side in the drawing) And the seal seal 44 are difficult to see from the back side (lower part in the drawing), and the locking pin 42 and the seal seal 44 on the back side are hard to see from the front side. On the other hand, in this embodiment, as shown in FIG. 11B, the locking pin 42 and the sealing from the back side to the front side are passed through the notch 28 formed in the vicinity of the locking pin 42 and the sealing seal 44. The seal 44 can be visually recognized, and the locking pin 42 and the sealing seal 44 on the back side can be visually recognized from the front side. When the board case 7 is illegally opened, an unauthorized person attaches a similar sticker on the damaged seal 44 or attaches the cut locking pin 42 with an adhesive to open the board case 7. It has been reported that it is difficult to find the trace of the seal, but in this embodiment, since the locking pin 42 and the sealing seal 44 can be visually recognized from both the front and back sides, even if the trace of opening is difficult to find. , Will surely be discoverable.

Although the configuration of the main part according to the second invention of the present invention has been described above, the substrate unit of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention. .. For example, the above embodiment is a board unit related to the main control board of the slot machine, but the present invention may be a board unit related to other control boards (sub-control board, image control board, etc.) of the slot machine. Alternatively, it may be a substrate unit related to another gaming machine (pachinko machine or the like).

Further, at least one of the gaming machine manufacturing company and the model number may be attached as identification information to the identification information display unit according to the present invention. Further, the identification information attached to each identification information display unit may be at least partially different. Further, the identification information attached to the identification information display unit is not limited to letters and numbers, and any information that can be optically identified is sufficient. Specifically, the identification information according to the present invention may be a figure such as a logo mark of a game machine manufacturing company, or may be a barcode read by a machine. Further, in the above embodiment, the identification information of the identification information display units 19a and 19b is printed by silk printing, but the identification information according to the present invention is not limited to the one attached to the identification information display unit by printing. .. For example, the identification information according to the present invention may be attached to the identification information display unit by affixing a sticker on which the identification information is printed, laser marking, patterning with a copper foil constituting a circuit wiring, or the like. ..

Further, in the above embodiment, the easy break line 27 for separating the identification information display unit is perforated, but the easy break line according to the present invention may be a V groove.

Further, the identification information display units 19a and 19b according to the above embodiment cut out the edges of the printed circuit board 15 in a U shape to separate them, but the identification information display unit according to the present invention is the printed circuit board. The corners may be cut out in an L shape to separate them. Further, in the above embodiment, the narrow printed circuit board main body 20 is interposed between the two identification information display units 19a and 19b, but the printed circuit board main body 20 is interposed between the two identification information display units 19a and 19b. It may be made to be directly adjacent to each other without providing.

Further, the printed circuit board 15 according to the above embodiment is arranged so that two identification information display units 19a and 19b are adjacent to each other on one side, but the printed circuit board according to the present invention has three or more identification information. The display unit may be arranged. Basically, the identification information display unit is separated except for one, so even if the printed circuit board 15 according to the above embodiment is provided with the third and fourth identification information display units, even if the third and fourth identification information display units are arranged. This is because at least one of the two identification information display units 19a and 19b is separated from the printed circuit board main body 20 to form a notch 28 in the printed circuit board 15.

Hereinafter, the main components of the first invention will be described.
As shown in FIG. 12, on the control board 8 of this embodiment, the identification information display unit 19b is continuous with the printed circuit board main body 20 via a linear easy break line 27. In the present embodiment, the easy breaking line 27 has a perforated shape formed by forming the penetrating portions 50a and 50b penetrating the plate material of the printed circuit board 15 in the thickness direction at intervals along the easy breaking line 27. I'm doing it. The penetrating portions 50a and 50b are composed of a circular hole-shaped circular penetrating portion 50a and a long groove penetrating portion 50b having a long groove shape along the easy breaking line 27, and the easy breaking line 27 has two circular portions. The penetrating portion 50a and the long groove penetrating portion 50b are repeated at intervals.

The circular through hole 50a constituting the easy break line 27 is a through hole having the same size as the through hole formed in the printed circuit board main body 20, and as shown in FIGS. 12 and 13, the inner surface thereof is the same as the through hole. Is coated with copper foil 54. Further, the circular penetrating portion 50a is filled with the solder alloy 52. This solder alloy is the same as that used for soldering electronic components mounted on the printed circuit board body 20. On the other hand, the long groove penetrating portion 50b is a groove-shaped through hole having the same width as the diameter of the circular penetrating portion 50a. The long groove penetrating portion 50b is only obtained by hollowing out the plate material of the printed circuit board 15, and its inner side surface is not covered with copper foil, and the inside is not filled with a solder alloy.

Further, as shown in FIG. 12, the front side of the identification information display unit 19b is covered with a linear copper foil 55 at the upper portion and the lower portion. The copper foil 55 is made of the same material and has the same thickness as the copper foil forming the circuit wiring on the front side of the printed circuit board body 20, but does not constitute the circuit wiring of the printed circuit board 15. ..

As described above, in this embodiment, by filling the circular penetrating portion 50a constituting the easy breaking line 27 with the solder alloy 52, the easy breaking line 27 is easily broken when the identification information display portion 19b is separated. It is possible to achieve both the difficulty of breaking the easy breaking line 27 due to vibration or impact. This is due to the characteristics of the solder alloy 52. Specifically, since the solder alloy 52 is a low melting point metal that exhibits creep characteristics and stress relaxation properties at room temperature, it is circular when a strong load is temporarily applied to the rupture line 27 due to vibration, impact, or the like. The solder alloy 52 filled in the penetrating portion 50a can generate a strong stress against a load, which can prevent the easy breaking line 27 from breaking due to vibration, impact, or the like. On the other hand, in order to separate the identification information display unit 19b from the printed circuit board main body 20, when the printed circuit board 15 is broken along the easy breaking line 27, a continuous force is applied in the direction of bending the printed circuit board 15, but the shape is circular. Since the solder alloy 52 filled in the penetrating portion 50a generates only a low stress with respect to such a continuous force, the printed circuit board 15 can be broken relatively easily at the easy breaking line 27. As described above, in this embodiment, the easy breaking line 27 is hard to break by vibration, impact, etc., and easily broken by bending, so that the identification information display unit 19a to be separated can be separated relatively easily. The identification information display unit 19b that should not be separated has an advantage that it is difficult to separate due to vibration, impact, or the like.

In particular, in this embodiment, since the inner surface of the circular penetration portion 50a is covered with the copper foil 54, there is an advantage that the solder alloy 52 can be strongly bonded to the printed circuit board 15.

Further, the circular through portion 50a of this embodiment has the same shape as the through hole (not shown) formed in the printed circuit board main body 20, and the copper foil 54 covering the inner side surface is copper covering the through hole. The solder alloy 52, which has the same material and the same thickness as the foil and is filled inside, is the same as the solder alloy used for soldering electronic parts to the through holes. Therefore, the circular penetration portion 50a can be formed in the step of forming a through hole in the printed circuit board 15, and the filling of the solder alloy 52 is also soldered in the step of soldering the electronic component to the printed circuit board 15. It can be done using the equipment used for soldering. Therefore, the circular penetrating portion 50a can be realized with less labor and cost.

Further, as described above, in the present embodiment, since the upper portion and the lower portion of the identification information display unit 19b are covered with the linear copper foil 55, the identification information display unit 19b is formed by the copper foil 55. There is an advantage that the plate material can be reinforced to prevent the identification information display unit 19b from being deformed due to external vibration or impact. Further, since the copper foil 55 can be performed at the same time as the circuit wiring is formed in the step of forming the circuit wiring on the printed circuit board 15, it can be realized with less labor and cost. Further, since the copper foil 55 does not form a circuit wiring, there is no problem in the circuit wiring of the printed circuit board 15 even if it is damaged.

Further, as described above, the inner side surface of the cover member 10 is formed with columnar ribs 30a and E-shaped ribs 30b protruding toward the back surface (see FIG. 7), and these are the outer peripheral portions of the printed circuit board 15. The control board 8 is stably supported in the internal space 32 of the board case 7 by abutting on the front side. Here, the identification information display unit 19b does not come into contact with the columnar ribs 30a or the E-shaped ribs 30b, and is not directly supported by the substrate case 7. Specifically, as shown in FIG. 14, the E-shaped rib 30b comes into contact with the printed circuit board main body 20 along the easy break line 27 and the outer circumference of the identification information display unit 19b, and is in the vicinity of the identification information display unit 19b. By supporting the printed circuit board main body 20 with, the identification information display unit 19b is indirectly supported by the substrate case 7.

In this way, if the board case 7 does not support the identification information display unit 19b but only the printed circuit board body 20, it is compared with the case where both the printed circuit board body 20 and the identification information display unit 19b are supported by the board case 7. Therefore, when vibration or impact is applied from the outside, the possibility that a strong load is applied to the easy break line 27 is reduced, and the vibrated identification information display unit is not damaged by contacting with the substrate case. Further, in such a configuration, since the printed circuit board main body 20 is supported along the easy break line 27 and the identification information display unit 19b, the vibration of the identification information display unit 19b even if the identification information display unit 19b is not directly supported. Can be minimized, and the load applied to the easy break line 27 can be minimized.

Although the configuration of the main parts according to the first invention of the present invention has been described above, the substrate unit of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention. .. For example, the above embodiment is a board unit related to the main control board of the slot machine, but the present invention may be a board unit related to other control boards (sub-control board, image control board, etc.) of the slot machine. Alternatively, it may be a substrate unit related to another gaming machine (pachinko machine or the like).

Further, at least one of the gaming machine manufacturing company and the model number may be attached as identification information to the identification information display unit according to the present invention. Further, the identification information attached to each identification information display unit may be at least partially different. Further, the identification information attached to the identification information display unit is not limited to letters and numbers, and any information that can be optically identified is sufficient. Specifically, the identification information according to the present invention may be a figure such as a logo mark of a game machine manufacturing company, or may be a barcode read by a machine. Further, in the above embodiment, the identification information of the identification information display units 19a and 19b is printed by silk printing, but the identification information according to the present invention is not limited to the one attached to the identification information display unit by printing. .. For example, the identification information according to the present invention may be attached to the identification information display unit by affixing a sticker on which the identification information is printed, laser marking, patterning with a copper foil constituting a circuit wiring, or the like. ..

Further, in the above embodiment, the easy breaking line 27 has a perforated shape formed by forming the circular penetrating portion 50a and the long groove penetrating portion 50b at intervals along the easy breaking line 27. The easily broken line according to the above may be composed of only one of the circular penetrating portion 50a and the long groove penetrating portion 50b. Further, in the above embodiment, all the circular penetration portions 50a are filled with the solder alloy 52, but in the easy break line according to the present invention, at least a part of the circular penetration portion and / or the long groove penetration portion is filled with the solder alloy. It is enough if it is filled.

Further, the identification information display units 19a and 19b according to the above embodiment cut out the edges of the printed circuit board 15 in a U shape to separate them, but the identification information display unit according to the present invention is the printed circuit board 15. The corners of the printed circuit board may be cut out in an L shape for separation, or the entire side of the printed circuit board 15 may be cut out for separation. Further, in the above embodiment, the identification information display unit 19b and the notch 28 are arranged adjacent to each other on one side of the printed circuit board 15, but the identification information display unit 19b and the notch 28 are arranged on different sides. It may be installed. Further, the printed circuit board according to the present invention may be one that separates the other from the three or more identification information display units, leaving one.

Further, in the above embodiment, the front side of the identification information display unit 19b is covered with the linear copper foil 55, but the front shape of the copper foil 55 can be changed as appropriate. Further, the copper foil 55 may be formed on the back surface side (opposite side of the printing surface of the identification information) of the identification information display unit 19b. Further, although the copper foil 55 of the above embodiment is exposed on the front side of the printed circuit board 15, it is covered with an insulating film (solder resist) like the copper foil constituting the circuit wiring of the printed circuit board 15. May be good.

Further, as a modified invention of the first invention of the present invention, it is also proposed that the easy break line 27 is not perforated but has a V-groove, and the groove portion of the V-groove is filled with a solder alloy. Even in such a configuration, when the solder alloy 52 filled in the V-groove generates strong stress against vibration or impact applied from the outside, when the identification information display unit 19b is bent and broken at the easy breaking line. Since only low stress is generated in the solder, the identification information display unit 19a to be separated can be separated relatively easily, and the identification information display unit 19b which should not be separated has an effect that it is difficult to separate due to vibration, impact, or the like.

Further, as a modified invention of the first invention of the present invention, it is also proposed to fill the through portions 50a and 50b of the easy break line 27 with a metal other than the solder alloy 52. In such a configuration, the metal filled in the penetrating portions 50a and 50b generates a strong stress against vibration or impact applied from the outside, so that the identification information display portion 19b is separated by vibration or impact. It becomes difficult.
