(Main control board)
Next, the main control board 63 will be described.

The main CPU 61 mounted on the main control board 63 has various functions realized by executing a program stored in the ROM 67 and various functions realized by controlling the hardware.

The main CPU 61 is a game of any one of a plurality of gaming states included in the slot machine 1 depending on the type of the winning combination group (having one or a plurality of combinations as constituent combinations) and the winning / non-winning of the winning combination. The game of the slot machine 1 is controlled to the state.

Further, the main CPU 61 adjusts the payout rate (number of medals won ÷ number of inserted medals × 100 [%]) based on a predetermined setting change operation for the power switch 50, the change processing start switch 56, and the reset switch 52. Change the settings for this (settings 1 to 6).

Further, the main CPU 61 selects one winning combination lottery table from a plurality of winning combination lottery tables based on the controlled game state type and the set setting values (settings 1 to 6). In this combination lottery table, for each of the plurality of preset winning combination groups, the winning combination group and the range of the lottery value at which the winning combination group wins the combination lottery are stored in association with each other.

Extract. Then, the main CPU 61 determines whether or not the winning combination group is won by using the selected combination lottery value table and the extracted lottery value.

Further, when the start switch 19 is operated by the player, the main CPU 61 starts the rotation of each reel 13L, 13M, 13R, and the detection signals of the left / middle / right position sensors 55L, 55M, 55R and the left / The rotation positions of the left, middle, and right reels 13L, 13M, and 13R are detected based on the number of supply pulses to the reel motors 14L, 14M, and 14R that drive the middle and right reels 13L, 13M, and 13R, respectively. The main CPU 61 is in a state of accepting the operation of each of the stop switches 21L, 21M, 21R as an effective operation when all the reels 13L, 13M, 13R rotate at a constant speed. When the player operates each of the stop switches 21L, 21M, 21R in this state, the main CPU 61 determines the detected rotation positions of the left, middle, and right reels 13L, 13M, and 13R, and each stop switch by the player. Based on the operation mode of 21L, 21M, 21R (for example, push order and operation timing) and the winning combination lottery result, each reel is within a preset number of sliding frames (retractable range: usually, maximum 4 frames). Stop control is performed so that 13L, 13M, and 13R stop.

After all the reels 13L, 13M, 13R have stopped rotating, the main CPU 61 has a symbol combination in which the symbol combinations of the winning lines of the reels 13L, 13M, 13R correspond to the winning combinations that constitute the winning combination group won by the combination lottery. If the symbol combination of the winning line is a symbol combination corresponding to the winning combination, it is determined that the winning combination has been won, and if not, it is determined that the winning combination is lost. When the main CPU 61 determines that a winning combination forming a winning combination group has been won by a combination lottery, if it is a winning combination with a medal payout, the hopper unit 43 is operated to win the winning combination. The corresponding number of medals are paid out. However, if the number of credit medals stored has not reached the upper limit (for example, 50 in this embodiment), the main CPU 61 increases the number of credit medals by the number of payouts.

Further, the main CPU 61 switches between medal acceptance and non-acceptance by controlling the operation of the medal selector 48.

Further, the main CPU 61 is set, a game state, information on a combination lottery result, information on a symbol determination result, a rotation / stop state of each reel 13L, 13M, 13R, a medal payout state, and an opening or closing of the front door 5.

A command for transmitting to the sub control board 73 (sub CPU 71) is generated, and the generated command is transmitted to the sub CPU 71 of the sub control board 73. The command is transmitted from the main control board 63 to the sub control board 73 in one way.

(Sub control board)
Next, the sub control board 73 will be described. The sub-control board 73 receives a command transmitted from the main control board 63, and performs an effect according to the operation and state of the main control board 63. The sub CPU 71 mounted on the sub control board 73 has various functions realized by executing a program stored in the memory 75 and various functions realized by hardware.

The sub CPU 71 receives commands including various data transmitted by the main control board 63 (main CPU 61). Then, the sub CPU 71 determines the content of the effect according to the received command, and according to the content of the determined effect, for example, performs display control for displaying an image such as a moving image on the liquid crystal display 27, or a speaker. Controlling the output of audio from the 31L and 31R, controlling the light sources of the upper lamp section 33 and the lower lamp section 37L and 37R to blink all at once or individually, and controlling the effect based on the operation of the effect button 42.

A lock member holding frame 136 is formed on the right side wall of the base member 111, and the lock member 112 is held by the lock member holding frame 136 with the locking pin 142 facing inward. Then, as shown in FIG. 7, when the locking member 112 is pushed inward, the locking pin 142 penetrates the right wall of the cover member 110 and the base member 111, and the right wall of both members 110 and 111 is the locking pin. Engaged by 142, the sealing structure 40 seals the substrate case 107.

As shown in FIG. 7, when the substrate case 107 is sealed by the sealing structure 40, the substrate case 107 cannot be opened unless an opening is formed in the cover member 110 or the base member 111. It is difficult to pull out the locking pin 142 having the barb formed from the right side walls of both members 110 and 111, and a cutting tool is inserted inside the board case 107 to insert the locking pin 142 inside the board case 107. This is because the engagement between the cover member 110 and the base member 111 cannot be released unless the cover member 110 and the base member 111 are disengaged. Therefore, in this embodiment, a rectangular thin-walled portion 126 capable of easily forming an opening for inserting a cutting tool is provided on the front side portion of each sealing structure 40 of the cover member 110.

As described above, in this embodiment, the substrate case 107 is sealed by the sealing structure 40, and when the substrate case 107 is opened, the locking pin 142 of the locking member 112 must be cut. That is, in this embodiment, when the substrate case 107 is opened, a trace of opening remains on the locking pin 142. Therefore, in this embodiment, by checking whether or not the locking pin 142 is disconnected, it is possible to confirm whether or not the substrate case 107 is opened without permission. In the sealing structure 40 according to the present embodiment, the cover member 110 and the base member 111 are engaged with each other by the lock member 112, but in addition to the lock member 112 or in place of the lock member 112, the cover member A sealing sticker attached so as to straddle the 110 and the base member 111 may be adopted.

FIG. 8A is a front view of the substrate unit 6. As shown in FIG. 8A, the substrate case 107 is provided with a rectangular sealing information recording unit 150 at the center of the front surface. FIG. 8B is an enlarged view of the sealing information recording unit 150. As shown in FIG. 8A, the sealing information recording unit 150 is for recording information related to the sealing of the substrate case 107 by the sealing structure 40. Specifically, the seal information recording unit 150 is provided with four seal information entry fields 151 to 154 for entering the date when each lock member 112 is used and the person in charge of using the lock member 112. More specifically, at the manufacturing site of the board unit 6, when the main control board 63 is housed in the board case 107 and the lock member 112 is pushed in from the outside to seal the board case 107, the date and the name of the person in charge Is entered in the first sealing information entry field 151 with a pen or a stamp. Next, at the manufacturing site of the slot machine 1, when the lock member 112 is pushed in from the outside and the board unit 6 is locked to the mounting bracket 109b fixed to the housing 3, the second sealing information entry field 152 Fill in. Then, after the slot machine 1 is shipped, when the board case 107 is opened for inspection at the amusement park and the lock member 112 is pushed in again from the outside to seal the board case 107, the third sealing information entry field 153 is used. Fill in. Finally, in order to return the board unit 6 to the manufacturer, when the board unit 6 is removed from the slot machine 1 and the lock member 112 is pushed in again from the outside to seal the board case 107, a fourth sealing information entry field is displayed. Fill in 154. Further, an identification information printing unit 155 and a two-dimensional code printing unit 156 are provided above the sealing information recording unit 150. Although not shown, the identification information printing unit 155 is printed with identification information (main board number) assigned to the main control board 63 as information related to sealing. Further, a two-dimensional code for recording the identification information and the like is printed on the two-dimensional code printing unit 156.

Further, as shown in FIG. 8A, a concavo-convex portion 200 (instruction means) indicating a sticking position of the sealing information recording unit 150 is provided in the front central portion of the substrate case 107, and the sealing information recording unit is provided on the concavo-convex portion. By pasting the 150 with the vertices and sides aligned, the sealing information recording unit 150 can be pasted without protruding from the specified position.

In the present embodiment, the indicating means is a concavo-convex portion, but the instructing means according to the present invention is not limited to the concavo-convex portion. For example, the surface of the substrate case 107 may be rough-processed, or the application area may be visually indicated by changing the transmittance by laser processing, printing, or the like. Further, in this embodiment, the affixing position is defined by aligning the upper left apex of the sealing information recording unit 150 with the apex of the indicating means, but the affixing position is defined by aligning another apex, or two adjacent sides. It may be the one that defines the sticking position together with.

The sealing information recording unit 150 is printed and formed on a transparent resin film coated with an adhesive on one side, and is attached to the front center portion of the substrate case 107 as shown in FIG. 8A. Here, as shown in FIG. 8B, each information is entered and printed in the seal information entry fields 151 to 154 of the seal information recording unit 150, the identification information printing unit 155, and the two-dimensional code printing unit 156. An opaque underprint (filled area) with white ink is applied for ease of use. In addition, explanatory characters 158 and borders 157 such as "main board number", "caulking use record", "use", and "date" are also printed on the sealing information recording unit 150, but these are also the same. Printed with opaque lines and characters with white ink. That is, in the sealing information recording unit 150 of this embodiment, the sealing information entry fields 151 to 154, the identification information printing unit 155, the two-dimensional code printing unit 156, the frame line 157, and the explanatory character 158 are opaque parts. Other parts are transparent. In particular, in the sealing information entry fields 151 to 154, the identification information printing unit 155, and the two-dimensional code printing unit 156, as described above, since each information is entered and printed, a continuous filling area for the base is used over a certain area. It has. Specifically, the sealing information entry fields 151 to 154, the identification information printing unit 155, and the two-dimensional code printing unit 156 are the character information printed on the fourth-type IC chip 164 and the fifth-type IC chip 165, which will be described later. Areas wider than the areas 180a and 190a for one character in the display areas 180 and 190 of 170d and 170e are continuously opaque. On the other hand, for the explanatory characters 158 and the border 157, since characters and thin lines are printed, a transparent area is provided between each printed portion instead of a continuous filled area, and one character is provided. Areas wider than the minutes areas 180a and 190a are not continuously opaque.

The transparency and opacity of the sealing information recording unit 150 are not limited to completely transparent (transparency 100%) and completely opaque (transparency 0%), but are transparent to the substrate case 107 and the sealing information recording unit 150. The transparent material is transparent so that the inside of the substrate can be visually recognized, and the transparent material is transparent so that the inside of the substrate cannot be visually recognized through the substrate case 107 and the sealing information recording unit 150.

FIG. 9 is a front view of the main control board 63. The main control board 63 constituting the board unit 6 is a main control board that comprehensively controls the progress of the game of the slot machine 1. The printed circuit board 115 of the main control board 63 has a horizontally long rectangular shape, and screw through holes 22 for fixing the printed circuit board 115 to the board case 107 are formed at the four corners thereof. The front side of the main control board 63 is a mounting surface on which electronic components are mounted, and various electronic components 161 to 167 are arranged on the front side of the printed circuit board 115. More specifically, six IC chips 161 to 166 having different forms are arranged on the front side of the printed circuit board 115. The first type IC chip 161 constitutes a microcomputer, the second type IC chip 162 is a transistor array and constitutes a switching element, and the third type IC chip 163 constitutes a regulator and is a fourth type. The IC chip 164 and the fifth type IC chip 165 form a buffer (Schmitt trigger buffer), and the sixth type IC chip 166 constitutes a negative circuit. Of these, the first type IC chip 161 is mounted in the socket 117 mounted on the printed circuit board 115, and the other IC chips 162 to 166 are soldered to the printed circuit board 115. The first type IC chip 161 and the second type IC chip 162, the third type IC chip 163, and the sixth type IC chip 166 are arranged one by one on the printed circuit board 115, but other model numbers. A plurality of IC chips 164 and 165 are arranged. Specifically, four fourth-type IC chips 164 (164a to 164d) and four fifth-type IC chips 165 (165a to 165d) are arranged. Here, a plurality of IC chips 164 and 165 having a model number are arranged so that the same type of IC chips are arranged in a vertical row. As shown in FIG. 9, character information 170a to 170f indicating the model number is printed on each of the IC chips 161 to 166, respectively. Specifically, the six types of IC chips 161 to 166 have model numbers "ICA001", "ICB002", "ICC003", "ICD004", "ICE005", and "ABC" (FIG. 10 (a)). (See) is printed on the upper surface side (front side of the main control board 63).

Further, as shown in FIG. 9, different part numbers are printed in the vicinity of the arrangement positions of the IC chips 161 to 166 on the printed circuit board 115 depending on the white ink. For example, "IC1" is printed near the arrangement position of the IC chip 161, "IC2" is printed near the arrangement position of the IC chip 162, and "IC3" is printed near the arrangement position of the IC chip 163. Printed, "IC4" to "IC7" are printed in order near the arrangement position of the IC chip 164 (164a to 164d), and "IC8" to "IC8" to the vicinity of the arrangement position of the IC chip 165 (165a to 165d). "IC11" is printed in order, and "IC12" is printed in the vicinity of the arrangement position of the IC chip 166. With this part number, a designer or an engineer can easily grasp which electronic component should be arranged at which position without checking the model number of the electronic component.

Further, as shown in FIG. 9, an LED array 167 for checking the operating state of various switches is arranged on the upper left portion of the printed circuit board 115. Further, the connectors 16a, 16b, 16c are mounted in the lower center of the printed circuit board 115. The electronic components 161 to 167 illustrated and described above are a part of those arranged on the printed circuit board 115, and although not shown, other electronic components are on the front side of the printed circuit board 115. Multiple components (capacitors, resistors, diodes, etc.) are mounted. Further, although not shown in FIG. 9 and the like, a wiring pattern made of copper foil is formed on the front and back surfaces of the printed circuit board 115 in a visible state.

Next, the configuration according to the main part of the present invention will be described.
Although not shown in FIG. 8 and the like, as described above, since the cover member 110 constituting the front side of the substrate case 107 is a molded product made of transparent resin, the substrate unit 6 is the front surface in this embodiment. The main control board 63 inside can be visually recognized through the cover member 110 from the side. However, since the sealing information recording unit 150 arranged at the center of the front surface of the cover member 110 has the opaque portion filled areas 151 to 156 as described above, it is in front of and behind the opaque portion filled areas 151 to 156. The main control board 63 is difficult to see from the front side with respect to the portion overlapping the above. In this embodiment, the electronic components 161 to 167 are arranged on the printed circuit board 115 so that the electronic components 161 to 167 can be easily grasped even if a part of the main control board 63 is difficult to see from the front side. Will be done. Hereinafter, a specific description will be given.

FIG. 10 (a) is an enlarged view of the front center portion of the main control board 63, and FIG. 10 (b) shows a state in which the main control board 63 is housed in the board case 107 (a state in which the sealing information recording unit 150 is attached). ) Is a view of the same portion as in FIG. 10A as viewed from the front side of the substrate unit 6. As shown in FIG. 10B, in this embodiment, when the substrate unit 6 is visually recognized from the front side, the six IC chips 164 and 165 overlap with the opaque portions 151 to 158 of the sealing information recording unit 150. As a result, three IC chips 164 and 165 are difficult to see due to the opaque portions 151 to 156 of the sealing information recording unit 150. Specifically, of the fourth type IC chips 164a to 164d arranged in a vertical row in the central portion, the display area 180a for one character in the display area 180 of the character information 170d of the IC chip 164b is the sealing information recording. Since it is smaller than the filled areas 155 and 156 of the part 150 and is arranged at a position where it partially overlaps the filled areas 155 and 156 of the sealing information recording part 150 when viewed from the front side, a part of the character information 170d is It is hidden in the filled areas 155 and 156, making it difficult to see. For example, in the character information 170d of the fourth type IC chip 164b, which is the second from the top, the "IC" of the "ICD004" is hidden behind the two-dimensional code printing unit 156, and the remaining "D004" is "004". Is hidden behind the identification information printing unit 155, making it difficult to see.

Further, the fifth type IC chips 165a to 165d arranged in a vertical row on the right side of the fourth type IC chips 164a to 164d are also for one character in the display area 190 of the character information 170e of the IC chips 165b and 165d. The display area 190a is smaller than the filled areas 151 and 153 of the sealing information recording unit 150, and is arranged at a position partially overlapping the filled areas 151 and 153 of the sealing information recording unit 150 when visually recognized from the front side. A part of the character information 170e is hidden in the filled areas 151 and 153 of the sealing information recording unit 150, making it difficult to see. For example, in the character information 170e of the fifth type IC chip 165b, which is the second from the top, "E005" of "ICE005" is hidden behind the first seal information entry field 151, and the fourth type from the top, the fifth type. All the character information 170e of the IC chip 165b is hidden behind the third sealing information entry field 153, making it difficult to see.

Here, regarding the fifth type IC chip 165c, although the “E005” part of the character information 170e is hidden behind the explanatory character 158 of the opaque portion, the explanatory character 158 is the display area 190 of the character information 170e. In a region wider than the display area 190a for one character in the above, there is a continuously non-opaque region and a partially transparent region. Therefore, the visual recognition of the character information 170e is relatively easier than the visual recognition of the character information hidden behind the filled area. In particular, when checking the character information with the main control board 63 installed, the character information is checked by shining light, but it is difficult to see because the light does not reach the character information hidden behind the filled area. On the other hand, the character information hidden behind the explanatory characters 158 and the frame line 157 can be easily visually recognized because the light reaches the character information by changing the light irradiation direction. The display area for one character in the character information display area is a rectangular area that is slightly larger than each character of the character information engraved or printed on the IC package and surrounds each character of the character information. , As shown in FIG. 10A, it is an area corresponding to each character information of "ICD004" and "ICE005" (for example, an area 180a corresponding to "4").

Further, as shown in FIG. 10B, the part numbers "IC4" to "IC7" are printed on the right side of the fourth type IC chips 164a to 164d, and among them, the part number "IC5" is printed. Is arranged at a position where it overlaps with the filled area 155 of the sealing information recording unit 150 when visually recognized from the front side, so it is difficult to visually confirm which part should be arranged here. However, "IC4" and "IC6", which are part numbers continuous with "IC5", are not printed in the area where they overlap with the filled areas 151 to 156 of the sealing information recording unit 150, and "IC4" to "IC6" are printed. Since it is printed in a vertical row, it can be easily inferred that the part number that is difficult to see is "IC5".

Similarly, the part numbers "IC8" to "IC11" are printed on the left side of the fifth type IC chips 165a to 165d, but the part number "IC11" is sealed when visually recognized from the front side. Since the information recording unit 150 is arranged at a position where the entire area overlaps with the filled area 154, it is difficult to visually confirm which component should be arranged here. However, the part numbers "IC8" to "IC10" continuous with "IC11" are not printed in the area overlapping the filled areas 151 to 156 of the sealing information recording unit 150, and "IC8" to "IC11" are printed. Since it is printed in a vertical row, it can be easily inferred that the part number that is difficult to see is "IC11".

In this way, when visually recognized from the front side, the character information 170d, 170e indicating the model number is visually recognized for the IC chips 164b, 165b, 165d arranged at positions overlapping the filled areas 151 to 156 of the sealing information recording unit 150. It has become difficult. However, in this embodiment, the IC chips 164a, 165a having the same model number as these IC chips 164b, 165b, 165d are positioned so as not to overlap the opaque portions 151 to 158 of the sealing information recording unit 150 when visually recognized from the front side. The model numbers of the IC chips 164b, 165b, and 165d, which are difficult to see the character information 170d and 170e, can be estimated.

Specifically, as shown in FIG. 10B, with respect to the fourth type IC chips 164a to 164d, the top IC chip 164a completely overlaps with the opaque portions 151 to 158 of the sealing information recording unit 150. The character information 170d is easily visible from the front side because it is arranged at a position where it does not become. Also, regarding the fifth type IC chips 165a to 165d, the top IC chip 165a is arranged at a position where it does not overlap with the opaque portions 151 to 158 of the sealing information recording unit 150, and the character information 170e is displayed from the front side. It is easy to see. On the other hand, the IC chips 164c, 164d, 165c in which the character information 170d and 170e are not easily visible and the IC chips 164b, 165b and 165d in which the character information is difficult to see are partially opaque portions 151 to 158 and filled areas 151 to 156 of the sealing information recording unit 150. Although they overlap, the whole is not hidden and the shape of the package and pins can be seen to some extent, so even if the model number cannot be read, the characteristics of the shape can be compared with the surrounding IC chips 161 to 165. Then, by searching for those having the same characteristics, it is possible to find IC chips 164a and 165a of the same type in which the character information 170d and 170e are arranged at positions that are easily visible. Further, since the part number of the part that is difficult to see is a part number that is continuous with the part number that can be seen or is a part number of a stepping stone, the part number that is difficult to see is an electronic part of the same type as the part number that can be seen. Can be estimated to be. Therefore, in the present embodiment, the character information 170d of the fourth type IC chips 164c and 164d, which are not easy to see, and the fourth type IC chip 164b, which is difficult to see, are based on the characteristics of the visible form. By finding an IC chip 164a having the same model number at a position where 170d can be easily seen and referring to the character information 170d printed on the upper surface thereof, those model numbers can be estimated. Similarly, for the fifth-type IC chip 165c, which is not easy to see the character information 170e, and the fifth-type IC chips 165b, 165d, which are difficult to see, the character information 170e is easy to see based on the characteristics of the visible form. By finding the IC chips 165a of the same model number at the position and referring to the character information 170e printed on the upper surface thereof, those model numbers can be estimated.

Here, with respect to the fourth type IC chips 164c and 164d which are not easy to see and the fifth type IC chips 165c which are not easy to see, a part of the character information 170d and 170e is the back side of the explanatory characters 158 and the frame line 157 as described above. Although it is hidden in, there is a partially transparent area that is not continuously opaque in a region wider than the display area 190a for one character in the display area 190 of the character information 170e, so that the character information 170d and 170e can be visually recognized. Is not as easy as the IC chips 164a and 165a, but it is relatively easier to see than looking at the character information hidden behind the filled area.

Further, as shown in FIG. 10B, even at a position overlapping the opaque portion, it is continuous in an area wider than the display area for one character in the character information display area such as the explanatory character 158 and the frame line 157. The sixth type IC chip 166 is arranged in a region that is not opaque. Regarding this, as described above, since it is relatively easy to visually recognize the character information overlapping the explanatory characters 158 and the frame line 157 of the sealing information recording unit 150, the fourth type IC chips 164a to 164d and the fifth type The sixth type IC chip 166 can be arranged without disposing the IC chips 164a and 165a of the same model number which are easily visible in order to estimate the model number, such as the IC chips 165a to 165d of the above. Because. In this way, thin opaque parts such as the frame line of the sealing information recording part can be easily confirmed by slightly changing the viewing angle or changing the light irradiation angle for viewing the character information. The parts can be arranged without being limited to the parts arranged outside the sticking area of the sealing information recording unit, and the degree of freedom in design can be increased.

As described above, in this embodiment, even if the character information 170d and 170e of some IC chips 164b, 165b and 165d are difficult to see due to the filled areas 151 to 156 of the sealing information recording unit 150, the same form is used. The model numbers of the character information 170d and 170e can be estimated by searching for IC chips 164a and 165a of the same type that can be easily visually recognized by using the property as a clue. Therefore, in this embodiment, the IC chips 164a to 164d and 165a to 165d are arranged at positions overlapping the sealing information recording unit 150, and the model number is difficult to grasp due to the filled areas 151 to 156 of the sealing information recording unit 150. There is an advantage that the chips 164b, 165b, 165d can be reduced as compared with the conventional configuration. In particular, in this embodiment, in the front view, the filling of the sealing information recording unit 150 is applied to all the IC chips 164b, 165b, 165d in which the filled areas 151 to 156 of the sealing information recording unit 150 and the character information 170d, 170e overlap. Since the IC chips 164a and 165a of the same type are arranged at positions where the areas 151 to 156 and the character information 170d and 170e do not overlap, it is difficult to visually recognize the character information 170d and 170e by the filled areas 151 to 156 of the sealing information recording unit 150. There is an advantage that the model numbers of all the IC chips 164a to 164d and 165a to 165d can be grasped.

In particular, in this embodiment, among the IC chips 164b, 165b, 165d in which the character information 170d and 170e are difficult to see, the two IC chips 164b and 165b arranged at the upper part are as shown in FIG. Since the character information 170d is arranged so as to be vertically adjacent to the IC chips 164a and 165a of the same type that are easy to see, the IC chips 164a and 165a of the same type that are easy to see the character information 170d and 170e can be easily found. In addition, there is an advantage that it can be strongly estimated that both have the same model number from the arrangement relationship of the two adjacent to each other.

Further, as shown in FIG. 10B, it is assumed that the uneven portion 200 of the substrate case 107 is displaced vertically and horizontally from the determined position by defining the pasting area so that the filled areas 151 to 156 of the sealing information recording unit 150 are displaced from the determined positions. It is possible to prevent the part other than the part that has been used from being difficult to see.

Further, as shown in FIG. 10B, the character information 170d and 170e of the IC chips 164a and 165a do not overlap with the uneven portion 200 of the substrate case 107 in the front view. This is because the uneven portion 200 is roughened so that it can be easily seen by the operator, or the thickness of the substrate case is changed, so that the transmittance is low. Therefore, the character information 170d, 170e of the IC chips 164a, 165a and the uneven portion 200 overlap in a front view, which hinders the estimation of the character information 170d, 170e hidden in the filled areas 151 to 156 of the sealing information recording unit 150. This is to prevent it from becoming a factor.

Further, in this embodiment, as shown in FIG. 11A, the IC chips 164a and 165a, which make it easy to see the character information 170d and 170e, and the character information 170d and 170e arranged so as to be adjacent to each other are used. IC chips 164b and 165b of the same type, which are difficult to see, are interconnected by wiring 172 on the printed circuit board 115, and as shown in FIG. 11B, the wiring 172 can be visually recognized from the front side of the board unit 6. It has become. Therefore, in this embodiment, there is an advantage that it is easy to estimate that they are the same type due to the interconnection relationship between the IC chips 164a, 164b, 165a, and 165b that are adjacent to each other when visually recognized from the front side. In particular, the wiring 172 that interconnects the IC chips 164a, 164b, 165a, and 165b is, as shown in FIG. 10B, one IC chip 164a, 165a and the other IC when visually recognized from the front side. Since the chips 164b and 165b are visually recognized so as to connect the two opposite side edges of the chips 164b and 165b, it is easier to estimate that they are the same type.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, 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 a main control board of a slot machine, but the present invention may be a board unit related to another control board (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).
