A board management number is assigned to each of these boards in the ball and ball game machine 100 and the spinning cylinder game machine 200 of the present embodiment.
Further, for each individual electronic component on the substrate, visible identification information is written to indicate the information. The identification information is, for example, a part number uniquely assigned to each electronic part. In particular, the identification information can be clearly recognized for the individual electronic components regardless of the density and arrangement of the electronic components on the substrate.
In the ball game machine 100 and the spinning game machine 200 according to the present embodiment, at least one or more of the boards corresponds to one of the following types regarding the identification information about each electronic component.

In addition, for each electronic component of the board attached to the gaming machine, the identification information of the electronic component is written on the board so that the board itself or a specific electronic component cannot be easily replaced. There is a request to make it difficult.
However, when a plurality of electronic components are densely installed on the substrate, it is difficult to accurately display identification information corresponding to each of the plurality of electronic components. Further, due to the increase in the number of electronic components in the board area due to the circuit configuration, the board area is pressed and it becomes difficult to display the identification information on the board. In such a situation, since many electronic components and identification information are mixed, it is difficult to specify at an early stage even if the electronic components are illegally replaced.
Therefore, in the present embodiment, an electronic component can be easily identified on an electronic circuit board by any one of the following types of techniques.

For example, specific notation examples of identification information for electronic components on a substrate are shown in FIGS. 14 to 17, which will be described later. Explain the types of information.

In the examples of FIGS. 9A, 9B, and 9C, since the identification information 25 is written in the vicinity of the extent that the correspondence between the electronic component 21 and the identification information 25 is not obscured, the operator or the like inspects the board. Thus, no problems arise when recognizing individual parts.
However, depending on the arrangement of the electronic components on the board, there are many cases where the identification information 25 cannot be written in the vicinity of the electronic component 21. Therefore, as described below, the above-described notation as the second identification information is also used.

9D, FIG. 9E, FIG. 9F, and FIG. 9G are examples corresponding to the second identification information, and are examples in which the identification information 25 is written at a position that cannot be said to be in the vicinity of the corresponding electronic component 21. .

A lead line 33 is extended from the surrounding line 31 of the electronic component 21 to show the corresponding identification information 25.
In the example of FIG. 9F, the identification information 25 “C101” for the electronic component 21 is shown at a position away from the electronic component 21. A surrounding line 32 is written around the identification information 25. A leader line 33 is written between the electronic component 21 and the surrounding line 32, and the correspondence between the electronic component 21 and the identification information 25 is shown.
In the example of FIG. 9G, a surrounding line 31 is written around the electronic component 21, and a surrounding line 32 is also written around the identification information 25. A leader line 33 is written between the surrounding lines 32 and 33 to indicate the correspondence between the electronic component 21 and the identification information 25.

In the example of FIG. 10A, a corresponding marker 34 “* A” is attached in the vicinity of the electronic component 21, and the same character “* A” is also displayed in the vicinity of the identification information 25 at a distant position as the second identification information. The correspondence is shown by attaching the marker 35.
In the example of FIG. 10B, an enclosure line 31 is provided around the electronic component 21, and a corresponding marker 34 “* B” is attached in the vicinity of the enclosure line 31. Correspondence is indicated by attaching a corresponding marker 35 of “* B” of the same character also in the vicinity of the identification information 25 at a distant position as the second identification information.

<5. Identification Information of Substrate of Embodiment>

The substrate 10 in the above-described embodiments such as the substrates 10A and 10B can clearly recognize the identification information 25 for the individual electronic components 21 regardless of the density and arrangement of the electronic components 21 on the substrates. ing. For this purpose, the first identification information such as the identification information 25 of FIGS. 9A, 9B, and 9C described above, and the second identification information such as FIGS. 9D, 9E, 9F, 9G, and 10 to 13 are used. And in combination.
On such a board, the board management number 50 is clearly described with a certain character size. For this reason, according to the plane size of each board | substrate and the convenience of the mounting area | region J, description 1 of description of the board | substrate management number 50 is described for every board | substrate or every board | substrate surface called the 1st main surface 10x and the 2nd main surface 10y. Select the format and the second description format.
Further, the substrate 10 according to the embodiment also realizes the ease of wiring, the ease of identifying terminals such as a BGA type IC, and the like.
Here, as the substrate configuration of the embodiment, details of arrangement and notation regarding the electronic component 21 (electronic component group 22) and identification information 25 (identification information group 27) shown in the above-mentioned type, and description of the substrate management number 50 Will be described.

First, referring to FIG. 18A and FIG. 18B, a description will be given of the combined use of first identification information and second identification information for identification information corresponding to each electronic component 21.
In FIG. 18B, identification information 25 as first identification information is written at a position from the electronic component 21 via the first distance K1, that is, in the vicinity of the electronic component 21. The first distance K1 is a distance where the correspondence relationship is clear without using the leader line 33 or the like. If the identification information 25 as such first identification information is written on all the electronic components 21 on the substrate 10, information about each electronic component 21 becomes clear.
However, there are many cases where the identification information 25 has to be written in the separated position via the second distance K2 longer than the first distance due to the convenience of the arrangement position of the electronic components and the dense arrangement. In such a case, the identification information 25 as the second identification information is written as shown in FIG. 18A.
For example, while the identification information group 27 is spaced apart from the electronic component group 22 by a second distance K2, which is a relatively long distance, the surrounding lines 31 and 32 are connected by the lead line 33. With such a notation, the correspondence between the electronic component group 22 which is a cluster of the dense electronic components 21 and the identification information group 27 is clarified. Of course, in addition to the example of FIG. 18A, the second identification information may be written in the manners exemplified in FIGS. 9D to 9G and FIGS. 10 to 13.

The substrates 10A and 10B shown in FIGS. 14 to 17 have such first identification information and second identification information as illustrated with reference numerals P1 to P7. In other words, the identification information 25 that can be visually recognized to indicate the information of the individual electronic components 21 mounted on the substrate 10 is expressed in the vicinity of the electronic component as a position via the first distance K1 from the electronic component. The first identification information and the second identification information written through the second distance K2 longer than the first distance K1 from the electronic component.
As described above, the identification information 25 is not necessarily only the first identification information in the vicinity of the electronic component 21, but the second identification information is used according to the component arrangement and its density, so that the identification information can be easily understood for each electronic component. Can be represented by state.

The first distance K1 does not indicate a specific value distance. The first distance K1 is a distance at which the notation position of the identification information 25 can be recognized as the vicinity of the electronic component 21, and is a distance that is recognized as being shorter than the second distance K2.
The second distance K2 does not indicate a specific value distance. The second distance K2 indicates a distance at which the notation position of the identification information 25 (identification information group 27) cannot be recognized as the vicinity of the electronic component 21, and is a distance that is recognized as being longer than the first distance K1. is there.
“Nearby” can be said to be a distance where the correspondence between the electronic component 21 and the identification information 25 is clear even without the leader line 33 and the corresponding marker 34. Therefore, when a specific electronic circuit board is viewed, if the identification information 25 is provided in the “neighborhood” in the above sense, the distance between the identification information 25 and the corresponding electronic component 21 is “ The first distance K1 ”.
Further, when there is identification information 25 provided at a position that is not “near” separated by a distance longer than the first distance K1, the distance between the identification information 25 and the corresponding electronic component 21 is “Second distance K2”.
The “second distance” is a distance between a certain electronic component 21 and the corresponding identification information 25, but as shown as a distance K2 ′ in FIGS. 18A and 18C, the electronic component group 22 and the identification information group. 27 may be considered as a distance between 27. That is, when considering the electronic component group 22 and the identification information group 27 as a reference, the “second distance” is a distance K2 ′ shown in the figure.

Further, the boards 10A and 10B are mounted on the boards 10 in such a state that the space between the adjacent at least one electronic component 21 is not enough to secure the notation area of the identification information 25 of a predetermined character size. With respect to the electronic component group 22 including a plurality of electronic components 21, identification information 25 based on the second identification information is written corresponding to each electronic component 21 in the electronic component group 22 (see symbols P5, P6, and P7).
This is shown in FIG. 19A. In the electronic component group 22 of FIG. 19A, the horizontal interval on the drawing of each electronic component 21 is “w1”, and the vertical interval is “h1”.
It is assumed that the identification information 25 to be written is, for example, “w2” in the character string direction and “h2” in the height direction. In this case, w1 <w2 and h1 <h2.
In such a case, it is difficult to write the identification information 25 in the vicinity of each electronic component 21. Even if it can be described, the correspondence is difficult to understand and the visibility is also lowered. Therefore, in such a case, in order to improve the visibility of the identification information 25, the identification information 25 separated from the electronic component 21 as the second identification information may be used.
If one of the conditions of w1 <w2 or h1 <h2 is satisfied, it is appropriate to write the identification information 25 as the second identification information.

  In particular, for the electronic component group 22 composed of a plurality of electronic components 21 of the same type, identification information 25 is written in the second identification information corresponding to each electronic component 21 in the electronic component group 22 (reference P5, (Refer to P6 and P7). For example, in a portion where capacitors are densely populated, even if “C101”, “C102”... Are added in the vicinity as identification information 25, it is difficult to understand the correspondence with the densely packed individual electronic components 21 (capacitors). It is to become.

There may also be an idea that the identification information 25 as the second identification information is written for all the electronic components 21 on the substrate 10. However, if the correspondence can be clearly described as the first identification information, it is desirable to use the first identification information. For example, if the second identification information is used for all the electronic components 21 including those that are not crowded, the identification information 25 is concentrated on the edge of the base 10 or the leader lines 33 are increased. This is because the correspondence may be difficult to determine.
That is, on the substrate 10, the identification information 25 is represented as first identification information as much as possible, but the identification information is represented in a portion away from the electronic component by adopting the second identification information for a dense electronic component. It is also appropriate to reduce. By using such first and second identification information in combination, it is possible to realize identification information notation with good visibility and information recognition.

Moreover, the board | substrates 10A and 10B are the examples in which the direction of the character string which forms all the identification information 25 as 1st identification information and 2nd identification information is made into the direction parallel to the long side of the corresponding electronic component 21. It was.
FIG. 19B shows the model. An electronic component 21H and an electronic component group 22H whose horizontal direction in the drawing is the long side direction, and an electronic component 21V and an electronic component group 22V whose vertical direction in the drawing is the long side direction are shown. The identification information 25 corresponding to them is all in the direction parallel to the long side of the electronic component 21 corresponding to the character string direction.
The rules in the character string direction as shown in FIG. 19B are also reflected in the identification information 25 (see symbols P1 to P7) on the substrates 10A and 10B in FIGS. That is, the identification information 25 is all in the character string direction parallel to the long side of the corresponding electronic component 21. Further, even when there is an electronic component 21 arranged in the electronic component group 22 so that the long side direction is different, as in the part indicated by reference numeral P7 in FIG. 15, each identification information in the identification information group 27 is matched accordingly. Reference numeral 25 denotes a direction parallel to the long side of each corresponding electronic component 21.

The first identification information can be easily viewed by matching the long side direction of the electronic component 21 and the character string direction as described above.
The second identification information can also easily recognize the identification information 25 corresponding to the electronic component 21 by setting the long side direction of the electronic component 21 to the character string direction. That is, for the second identification information at a distant position, the corresponding electronic component 21 is easily discriminated by the vertical and horizontal regularities in the character string direction.

In any case, the recognition of the correspondence and the visibility of the identification information 25 can be improved by notifying all the identification information 25 according to the rule that the long side direction of the electronic component 21 and the character string direction are matched. Can do.
However, there may be exceptions depending on circumstances. For example, depending on the component arrangement on the substrate 10 and the allowance for notation, some of the rules may be out of the rule. In that case, it is desirable to make the correspondence clear by using a leader line 33 or by marking it in the vicinity of the electronic component 21.
If the above-mentioned rules in the character string direction are applied to a part (for example, most) of the identification information 25 on the substrate 10, not necessarily all of the identification information 25, the discriminability and visibility of the correspondence relationship are Can be improved.
For the electronic component 21 having a substantially square or substantially circular planar shape, either the horizontal direction or the vertical direction described in FIG. 19B may be considered as the long side direction.

In addition, in the substrates 10A and 10B, adjacent second identification information corresponds to the plurality of second identification information in the identification information group 27 (second identification information group) based on the plurality of identification information 25 as the second identification information. They are shown separated by a third distance shorter than the distance (second distance K2 ′) between the electronic component group and the second identification information group (see symbols P5, P6, P7).
18A, the adjacent identification information 25 in the identification information group 27 is shown separated by a third distance K3. The third distance K3 is shorter than the second distance K2 ′.
By using the second identification information, the identification information can be easily understood for each component regardless of the component arrangement and its density, but a large number of identification information 25 is packed in the second identification information group. This makes it difficult to see the display. On the other hand, if the group as the identification information group 27 is not maintained, the correspondence with the electronic component group 22 becomes difficult to understand.
Therefore, in the identification information group 27, each identification information 25 is arranged at a relatively short third distance K3. As a result, the unity as the identification information group 27 can be maintained, the recognizability of the correspondence with the electronic component group 22 can be improved, and the identification information 25 in the identification information group 27 can be easily viewed.

In particular, the range of the identification information group 27 is further clarified by the enclosure line 32 by notifying the plurality of identification information 25 in the identification information group 27 enclosed by the enclosure line 32 as shown in FIG. In addition, the identification information 25 can be easily viewed, and the recognizability of the correspondence with the electronic component 21 can be improved.
In the above description, the third distance K3 does not indicate a specific distance. The third distance K3 is a notation interval between adjacent identification information 25. In the present embodiment, the third distance K3 is a distance that is recognized as being shorter than the second distance K2 ′ (or K2).
In addition, in all the identification information groups 27 on the substrate 10, the distance between the identification information 25 may not be the third distance. For example, when a plurality of character strings each having the identification information 25 are arranged only in the vertical direction, the third distance K3 may not be considered.

Further, in the substrates 10A and 10B, the identification information group 27 (second identification information group) corresponds to the electronic component group 25 of the same type of electronic component, and each identification information 25 in the identification information group 27 is the same type of electronic component. 22 (see reference numerals P5, P6, P7).
For example, in FIG. 18A, with respect to the electronic component group 22 group of the electronic component 21 as the capacitor, the identification information group 27 includes “C101”, “C102”. Further, in FIG. 18C, “R10”, “R11”,..., Which are identification information 25 as resistors, are grouped in the identification information group 27 with respect to the electronic component group 22 group of electronic components 21 as resistors.

Thus, the electronic component group 22 and the identification information group 27 are applied to the same type of electronic component. Thereby, the correspondence between the electronic component group 22 and the identification information group 27 becomes clearer, and it can be easily understood which electronic component 21 each identification information 25 is information about.
In particular, since each identification information 25 in the identification information group 27 surrounded by the enclosure line 32 as shown in FIG. 18A is the identification information about the same type of electronic component, a group of identification information groups can be easily grasped. .

In addition, by applying to the same kind of electronic component 21 in this way, the notation of the identification information 25 in the identification information group 27 can be made more efficient.
For example, FIG. 18D shows various examples of efficiency in the notation. For example, when the identification information 25 of nine capacitors is collected, it is possible to write only one “C” indicating a capacitor as an initial of the identification information 25 at the head as shown.
That is, as shown in the upper left of FIG. 18D, except for one piece of identification information “C101”, it may be simply expressed as “102” “103”.
Further, as shown in the upper right of FIG. 18D, “C” may be added in the middle of the surrounding line 32, and the inside of the surrounding line 32 may be expressed as “101”, “102”, “103”. .
Further, as shown in the lower left of FIG. 18D, “C” may be attached in the vicinity of the surrounding line 32, and the inside of the surrounding line 32 may be expressed as “101”, “102”, “103”, and “109”. .
Further, as shown in the lower right of FIG. 18D, after adding “C” to the inside of the surrounding line 32, they may be expressed as “101” “102” “103”.
In this way, the notation efficiency is reduced and the total number of characters in the identification information group 27 is reduced, so that the area size required for the identification information group 27 can be reduced, and the identification information group 27 can be arranged for convenience of component placement on the board 10. Even when it is difficult to secure a large area.

Note that the set of all the electronic component groups 22 and the identification information group 27 is not necessarily formed for the same type of electronic component. For example, a resistor and a capacitor are mixed in one electronic component group 22, and the corresponding identification information group 27 includes identification information 25 such as “C101” corresponding to the capacitor and identification information 25 such as “R10” corresponding to the resistor. May be mixed.
By providing at least a part of the electronic component group 22 and the identification information group 27 for the same type of electronic component, the correspondence and recognition of the group can be improved.

The substrates 10 </ b> A and 10 </ b> B have a surrounding line 32 written for the second identification information 25. For example, as shown in FIG. 18A, a surrounding line 32 is written around the identification information group 27 (second identification information group) (see symbols P5, P6, and P7).
Further, as shown in FIGS. 9F, 9G, 10C, and 10D to 10G, an enclosure line 32 may be provided around one piece of identification information 25.
Thus, the recognizability of 2nd identification information can be improved by providing a surrounding line with respect to 2nd identification information. In particular, when the second identification information is represented as the identification information group 27, by providing the enclosure line 32, it is possible to improve the group recognizability of the identification information group 27 and clarify the range corresponding to the electronic component group 22.

Also, the electronic component corresponding to the second identification information in which the enclosure line 32 is indicated also has an enclosure line 31 on the component side.
For example, in the portions indicated by reference signs P5, P6, and P7, the electronic component group 22 is also provided with a surrounding line 31. Further, as shown in FIGS. 9G and 10F, there may be a case in which a surrounding line 31 is provided for the single electronic component 21 corresponding to the second identification information.
In this way, the electronic component 21 (electronic component group 22) and the identification information 25 (identification information group 27) as the second identification information are surrounded by the component-side enclosure 31 and the identification-information-side enclosure 32, respectively. As a result, the respective recognizability can be improved, the correspondence can be clarified, and the visibility can be improved.

For example, as shown in FIGS. 9E, 10B, 10H, 11C, 12B, and 13E, no enclosure line is provided on the identification information 25 side, and an enclosure line 31 is provided on the electronic component 21 (electronic component group 22) side. There are also examples.
In any case, by providing the surrounding line 31 on the electronic component 21 (electronic component group 22) side, the recognizability of the electronic component 21 corresponding to the identification information 25 can be enhanced, or the range of the electronic component group 22 can be clarified.

Further, the electronic component group 22 can be set flexibly by the surrounding line 31 on the electronic component 21 side.
For example, two electronic component groups 22 are set by an encircling line 31 in two portions at substantially the center among the three portions denoted by reference numeral P5 in FIG. Further, in FIG. 21, a portion where the electronic components 21 in the substantially center are densely divided into four electronic component groups 22 by a surrounding line 31.
Since the electronic component group 22 can be flexibly set by the surrounding line 31 without depending on the component arrangement in this way, for example, according to the convenience of the notation area of the corresponding identification information group 27, the electronic component group is indicated by the surrounding line 31. 22 can be set. Thereby, easy-to-see identification information notation can be realized according to the arrangement on the substrate 10, the substrate area, and the like.
In other words, the electronic components 21 that are densely arranged in a certain area do not necessarily have to be one electronic component group 22. By distinguishing the electronic component group 22 according to the state of the notation area of the identification information group 27 on the substrate 10 and providing the identification information group 27 for each, it is possible to realize easy-to-read identification information notation.

The boards 10A and 10B correspond to the surrounding line 31 around the electronic component 21 (electronic component group 22) and the surrounding line 32 around the identification information 25 (identification information group 27) as the second identification information. There are provided portions where the markers 34 and 35 are indicated to indicate the corresponding relationship (see symbols P6 and P7).
Thereby, the correspondence between the surrounding lines 31 and 32 is clearly shown. In particular, when the lead wire 33 cannot be connected between the surrounding lines 31 and 32, or when the lead wire 33 is possible but becomes too long, or the lead wire 33 becomes difficult to see due to a wiring pattern or the like, the corresponding marker It is preferable to indicate the correspondence using 34 and 35.

  In addition, it is not necessarily the example which shows the surrounding lines 31 and 32 with the corresponding markers 34 and 35, FIG. 10A-10C, FIG. 10E, FIG. 10G, FIG. FIG. 13E may be used. That is, in some cases, the corresponding markers 34 and 35 may be attached without providing the enclosure line 31 to both or one of the electronic component 21 (electronic component group 22) and the identification information 25 (identification information group 27). Even in such a case, if the range of the electronic component group 22 and the range of the identification information group 27 are clear, the correspondence relationship at positions separated by the corresponding markers 34 and 35 can be clarified.

In addition, on the boards 10A and 10B, the leader line 33 is written so as to indicate the correspondence with the electronic component 21 (electronic component group 22) with respect to the identification information 25 (identification information group 27) as the second identification information. (See symbols P2 and P5).
The correspondence between the second identification information and the electronic component 21 can be clarified by the leader line 33. There are examples as shown in FIG. 9D to FIG. 9G and FIG. 11A to FIG.

In addition, in the boards 10A and 10B, a component-side surrounding line 31 is written around one electronic component 21 or around an electronic component group 22 of a plurality of electronic components 21, and one piece of identification information 25 as second identification information. The identification information side enclosure line 32 is written around the identification information group 27 or the identification information group 27, and the lead line 33 is written between the corresponding component side enclosure line 31 and the identification information side enclosure line 32. (See symbol P5, FIG. 9G).
For example, as shown in FIGS. 9G and 11E, the electronic component 21 (electronic component group 22) and the identification information 25 (identification information group 27) are surrounded by surrounding lines 31 and 32, respectively, and the correspondence relationship is shown by the leader line 33. By doing so, the recognizability of the correspondence between the electronic component 21 and the identification information 25 can be enhanced.
Note that it is not always necessary to provide the leader line 33 between all the electronic components 21 (electronic component group 22) and the identification information 25 (identification information group 27). In the portion where the leader line 33 is provided, the above-described effects can be obtained.

In the boards 10A and 10B, the plurality of pieces of identification information 25 in the identification information group 27 are represented by the same arrangement relationship as the arrangement relationship of the plurality of electronic components 21 in the corresponding electronic component group 22 (reference numerals P5, P6, P7). reference).
For example, in FIG. 21, four groups are illustrated as the electronic component group 22 and the identification information group 27. In any of the identification information groups 27, the identification information 25 such as “C101” is written in the same arrangement relationship as that of each electronic component 21 in the electronic component group 22 indicated by the lead line 33.
For example, for the electronic component group 22 in which the electronic component 21 is arranged in 4 rows and 3 columns, the identification information group 27 also describes the identification information 25 in 4 rows and 3 columns. Further, when the electronic component 21 is arranged such that the first row has three, the second row has four, and the third row has three, the corresponding identification information group 27 has three first rows and four second rows. The identification information 25 is written in an arrangement of three in the third row.
Thereby, it is possible to make it very easy to understand which electronic component 21 in the corresponding electronic component group 22 each identification information 25 in the identification information group 27 corresponds to. Since the shapes of the identification information group 27 and the electronic component group 22 are similar, it is easy to understand the correspondence between the groups, and the relationship between each electronic component 21 and each identification information 25 is easy to grasp from the positional relationship within the group. Because.

Further, the electronic component group 22 and the identification information group 27 whose arrangement relations are matched in this way are clarified by the surrounding lines 31 and 32 and further corresponded by the leader line 33, so that each identification information 25 and the electronic component 21 are matched. The remarkability and recognizability are significantly improved.
Further, when the electronic component group 22 and the identification information group 27 cannot be connected by the lead line 33, it is preferable that the correspondence relationship is indicated by the corresponding markers 34 and 35.
Note that in all the identification information groups 27 on the substrate 10, the arrangement of the individual identification information 25 is not necessarily the same as the arrangement of the electronic components 21 of the corresponding electronic component group 21. If at least the identification information 25 has the identification information group 27 in which the arrangement of the identification information 25 is the same as the arrangement relationship of the electronic components 21 of the corresponding electronic component group 21, the above-described effects can be obtained in the identification information group 27. Of course, if the arrangement of the identification information 25 in all the identification information groups 27 is the same as the arrangement of the respective electronic components 21 in the corresponding electronic component group 21, the recognizability improvement effect as a whole is great.

In addition, the boards 10A and 10B have lead lines 33 that are written so as to associate the electronic component 21 with the identification information 25 arranged on the board end side as viewed from the electronic component 21 (see reference numerals P2 and P5). .
For example, as shown in FIG. 21, a lead line 33 is provided from the electronic component 21 (electronic component group 22) on the substrate 10 toward the substrate edge, that is, the direction toward one of the end sides 11, 12, 13, and 14. The state of pointing to the identification information 25 (identification information group 27) is obtained by arranging the second identification information other than the central portion of the substrate.
Thereby, the information of the electronic component 21 in the central portion of the substrate having a relatively high component density can be clearly described by the second identification information in the vicinity of the end portion. Further, since the second identification information is not arranged at the center of the substrate, the identification information 25 itself as the second identification information can be easily seen.
It should be noted that all the leader lines 33 are not necessarily shown so as to be directed from the electronic component 21 (electronic component group 22) closer to the center of the board toward the outer edge of the board and to the identification information 25 (identification information group 27). This is because the presence of such a leader line 33 (that is, the positional relationship between the electronic component 21 and the identification information 25) can realize the efficiency of arrangement on the substrate and the visibility of the identification information 25.

Further, in the substrate 10A shown in FIGS. 14 and 15, each of the identification information 25 as the first identification information and the second identification information is either the first edge reference identification information or the second edge reference identification information. (See reference numerals P1 to P7 in FIGS. 14 and 15).
The identification information based on the first end side is that the character string direction is the first end side corresponding to the electronic component 21 in which the long side is arranged in parallel to the first end side (end side 12) of the substrate 10. And the first end side (end side 12) side is below the character.
The identification information based on the second end side means that the character string direction is the second end side corresponding to the electronic component 21 in which the long side is arranged in parallel to the second end side (end side 13) of the substrate 10. Is the identification information 25 in which the second end side (end side 12) side is below the character.

This will be described with reference to FIGS. 20A and 20B. 20A shows, for example, the first main surface 10x of the substrate 10, and FIG. 20B shows the second main surface 10y. Although the identification information 25 such as “C101” is illustrated here, any identification information 25 is either based on the end side 12 or based on the end side 13.
That is, in the identification information 25 corresponding to the electronic component 21 whose long side is parallel to the end side 12, the character string direction is parallel to the end side 12, and the end side 12 is the lower side (the direction indicated by the arrow DR1 is the upper side). .
In the identification information 25 corresponding to the electronic component 21 whose long side is parallel to the end side 13, the character string direction is parallel to the end side 13, and the end side 13 is the lower side (the direction indicated by the arrow DR2 is the upper side).
The fact that each piece of identification information 25 for each electronic component 21 is either a first edge reference or a second edge reference means that all identification information 25 is represented by two sides (end edge 12 and This means that it is easy to read when viewed from the end 13) side.
In addition, since the direction of the character string is parallel to the long side of the electronic component 21, it is easy to grasp the correspondence between the electronic component 21 and the identification information 25.
As a result, the correspondence of the identification information 25 is clarified and the identification information 25 is easy to read.

In addition, such a substrate 10 has a directionality in which either the first end side (end side 12) or the second end side (end side 13) is the lower end, and is attached to the ball game machine 100 or the revolving game machine 200. It is appropriate to ensure that it is attached.
In FIG. 20C, the outlines of the housings of the ball game machine 100 and the revolving game machine 200 are indicated by broken lines, but the substrates 10-1, 10-2, and 10-3 are indicated by the arrows attached in FIGS. It is attached so that the direction indicated by DR1 is upward.
By doing in this way, the identification information 25 based on the first edge (edge 12) is in a state that can be normally visually recognized by a viewer facing the gaming machine in a state of being attached to the gaming machine, The characters are not upside down and are very easy to see. For example, a posture facing the back surface of the ball game machine 100 (for example, see FIG. 31 to be described later), or the back panel of the front panel 202 by opening the front panel 202 of the swing game machine 200 (see FIG. 6), or a main body case In the posture facing the inside (see FIG. 7), the identification number 25 is not upside down for the viewer.
In addition, the identification information 25 based on the second end side (end side 13) is such that characters are horizontal when viewed from the viewer, but since the directions are aligned, it is not so difficult to read.

In addition, on both the front and back substrate surfaces of the first main surface 10x and the second main surface 10y, the identification information 25 is unified as either the first end side reference or the second end side reference.
By unifying the vertical direction on the front and back surfaces of the board 10, it is easy to see the identification information even when the board 10 is removed from the gaming machine, and the correspondence between the electronic component 21 and the identification information 25 is easy to grasp.
Further, for example, when considering a case where the first main surface 10x and the second main surface 10y are vertically attached to the gaming machine so that the end side 14 side is inserted, the second main side (end side 13) ) The reference identification information 25 is easy to see.

As described above, the substrate 10 is attached to the gaming machine in a state where the vertical direction of the characters forming the identification information is not opposite to the vertical direction of the gaming machine body. Specifically, the substrate 10 is attached to the gaming machine so that either the first end side (end side 12) or the second end side (end side 13) is located downward. This eliminates the identification information 25 that must be viewed in an inverted state on the board 10 attached to the ball and ball game machine 100 and the spinning cylinder game machine 200, so that the electronic component 21 can be easily identified. Can do.
It is best to set all the identification information 25 to be either the first edge reference or the second edge reference, but depending on the characteristics such as the shape of the electronic component 21, There may exist identification information 25 in which the vertical direction of the characters is exceptional. If the identification information 25 of the first edge reference and the second edge reference is dominant, the visibility of the identification information 25 can be improved as a whole substrate.

Also, the substrate 10B shown in FIGS. 16 and 17 is mounted in an oblique state in which the planar shape is a substantially square shape and each side of the substantially square shape is non-parallel to each end side (11 to 14) of the substrate. The electronic component 21 is provided. In FIG. 16, the identification information 25 is the electronic component 21 indicated as “IC13” to “IC17”.
In this way, by arranging some of the electronic components 21 in an oblique state, the wiring pattern can be easily routed on the substrate 10 and the manufacturing efficiency can be improved.

This will be described with reference to FIG. 23A. FIG. 23A shows an electronic component 21 </ b> S in an oblique state together with an electronic component 21 </ b> H whose long side is parallel to the end side 12 and an electronic component 21 </ b> V whose long side is parallel to the end side 13.
Attention is paid to the electronic components (IC) 21S whose identification information 25 is “IC100” and the electronic components 21H and 21V whose identification information 25 is “CN10” and “CN20”.
“IC100” has a large number of terminals, and connectors “CN10” and “CN20” are connected to a large number of wires. The electronic component 21 as a connector is usually disposed in the vicinity of the end on the substrate 10 in parallel with the end.
Here, when viewed from the connector “CN10”, two sides of “IC100” appear in the front. For this reason, it is easy to design the wiring 90 for the terminals on the two sides.
Further, when viewed from the lower right side of the drawing of “IC100”, the connectors “CN10” and “CN20” are seen in the diagonal direction on the front surface. Thereby, the design of the wirings 90 and 91 for the connectors “CN10” and “CN20” is easy.

  In other words, the plan view has a substantially square shape, and other electronic components 21H and 21V mounted in a state where each side of the substantially square shape is parallel to each end side (11 to 14) of the substrate 10. By providing the electronic component 21S mounted in an oblique state, the wiring pattern between the electronic components on the substrate 10 can be easily routed. This is because the electronic components 21H and 21V and the electronic component 21S can create a positional relationship in which it is easy to see the other side.

The direction of the character string forming the identification information 25 is a direction parallel to the long sides of the corresponding electronic components 21H, 21V, and 21S (see FIGS. 23, 16, and 17).
That is, the character string direction of the identification information 25 is parallel to the long side direction of the electronic component 21 in an oblique state. In addition, in the case of a substantially square planar shape, either may be the long side direction.
Accordingly, as the identification information 25, a character string parallel to the end side 12, a character string parallel to the end side 13, and a character string in an oblique direction exist. In this way, the correspondence between the identification information 25 as the second identification information and the electronic component 21 becomes clearer. That is, it is obvious that the oblique character string corresponds to the electronic component 21S in the oblique state.
On the electronic component side as well, an electronic component 21H parallel to the end side 12, an electronic component 21V parallel to the end side 13, and an electronic component 21S mounted obliquely are mixed, so that the visual discrimination of each electronic component 21 is achieved. Will improve.
In the case of the electronic component 21S, the direction of the character as the identification information 25 is inclined as compared with the character of the identification information 25 based on the first end side (end side 12), for example. Here, as described in FIG. 20, the board 10 is attached to the gaming machine in a state where the vertical direction of the characters forming the identification information 25 is not opposite to the vertical direction of the gaming machine body. For example, it is attached to the gaming machine so that the first end side (end side 12) is downward. In the case of the electronic component 21S as shown in FIG. 23, the direction of the characters as the identification information 25 is also not upside down when attached to the gaming machine body. That is, the lower side of the character has the end sides 12 and 14 obliquely downward, and is attached to the gaming machine so that one of the end faces is downward.
By doing so, even in the case of the electronic component 21S, the vertical direction of the characters forming the identification information is not opposite to the vertical direction of the gaming machine body when attached to the gaming machine. And visibility can be improved.

Further, among the electronic components 21 mounted on the substrates 10A and 10B, there is a bottom terminal type electronic component having a substantially square planar shape and a plurality of terminals arranged on the bottom surface of the chip. The bottom terminal type electronic component is, for example, a BGA type IC, a PGA (pin grid array) type IC, or the like. And the 1st terminal information which shows the terminal position of the column direction of the electronic component 21 and the 2nd terminal information which shows the terminal position of the row direction are described on the board | substrate 10 so that visual recognition is possible.
FIG. 22 shows an example of a BGA type IC 50. 22A is a plan view, FIG. 22B is a bottom view, and FIG. 22C is a front view. As illustrated, a large number of terminals 51 are formed in a matrix on the bottom side. In addition, as shown in FIG. 22D, there is a type in which the terminal 51 is not formed on the entire bottom surface and the terminal is not formed on a part of the bottom surface.
Such a BGA type IC 50 or the like in which the terminal is not exposed on the substrate 10 is difficult to visually distinguish the terminal.

Therefore, as shown in FIG. 22E, the first terminal information 55 and the second terminal information 56 are written on the side of the IC 50 so that the terminal arrangement can be recognized. For example, the first terminal information 55 is a terminal column number, and the second terminal information is a terminal row number. In FIG. 22E, the terminal column numbers “A” to “AH” of each column are shown as the first terminal information 55, and the terminal row numbers “1” to “28” of each row are shown as the second terminal information 56.
Note that not all terminal column numbers and terminal row numbers need to be written. For example, as shown in FIG. 22F, the terminal row numbers “A” and “AH” at the beginning and end may be written, and the terminal row numbers “1” and “28” at the beginning and end may be expressed. Of course, in addition to this, intermittent terminal column numbers and terminal row numbers may be used.

In the board 10B of FIG. 16, in the electronic component 21 of “IC17”, an example is shown in which the first terminal information 55 and the second terminal information 56 are represented as shown in FIG. 22E.
Further, in the substrate 10A of FIG. 14, in the electronic component 21 of “IC5”, the example in which the first terminal information 55 and the second terminal information 56 are represented as shown in FIG. 22F is shown.
As described above, by describing the first terminal information 55 and the second terminal information 56 for the bottom surface terminal-type electronic component in which the plurality of terminals 51 are arranged on the bottom surface of the chip, the terminal arrangement can be easily recognized visually.

In these cases, the first terminal information 55 is written on one side of the bottom terminal type electronic component, and the second terminal information 56 is written on a side different from the one side of the bottom terminal type electronic component. I try to write it.
By arranging the first terminal information 55 indicating the terminal position in the column direction and the second terminal information 56 indicating the terminal position information in the row direction on different sides of the electronic component 21, the column / row terminal information is obtained. Easy to recognize.
In the bottom terminal type electronic component, it is arbitrary which direction is the column direction or the row direction. A certain direction may be regarded as a column direction, and a direction perpendicular to the column direction may be regarded as a row direction.

Further, as shown in FIGS. 22E, 22F, and FIGS. 14 and 16, the characters as the first terminal information 55 and the characters as the second terminal information 56 are written in the same vertical direction. .
Thus, by unifying the vertical direction of the characters in the first terminal information 55 and the second terminal information 56, it is possible to make it easy to see the notation of each information and to grasp the terminal position.
This vertical direction is preferably matched with the direction of the identification information 25. For example, in the case of FIG. 14, it is the same as the character direction of the identification information 25 on the basis of the edge 12. In the case of FIG. 16, it is the same as the character direction of the identification information 25 of diagonal arrangement. By doing in this way, the visibility of the 1st terminal information 55 and the 2nd terminal information 56 can be improved.

The first terminal information 55 is represented by a first type character, for example, alphabet, and the second terminal information 56 is represented by a second type character, for example, a number.
By using different character types in this way, the first terminal information 55 and the second terminal information 56 can be easily distinguished from each other, and the recognizability can be improved.
In the electronic component 21 of “IC5” in FIG. 14, the first terminal information 55 and the second terminal information 56 have the same vertical direction as the identification information 25 based on the first edge (edge 12). It is said.
In the electronic component 21 of “IC17” in FIG. 16, the first terminal information 55 and the second terminal information 56 have the vertical direction of the characters in the same direction as the identification information 25 of “IC17”.
As described with reference to FIG. 20, the substrate 10 is attached to the gaming machine such that either the first end side (end side 12) or the second end side (end side 13) is downward. Then, similarly to the identification information 25, the first terminal information 55 and the second terminal information 56 are also upside down on the board 10 attached to the bullet ball game machine 100 or the spinning cylinder game machine 200. There is nothing. Thereby, the visibility of the 1st terminal information 55 and the 2nd terminal information 56 can be made favorable also in the state where it was attached to the game machine.

As described above, the terminal arrangement of the electronic component 21 (bottom terminal type electronic component) having a plurality of terminals 51 arranged on the bottom surface of the chip can be easily confirmed, which is convenient for manufacturing and inspection.
It should be noted that electronic parts 21 such as capacitors are easily arranged on the back surface of the BGA type IC. For example, in the case of the substrate 10B in FIGS. 16 and 17, on the second main surface 10y side, a large number of electronic components 21 such as capacitors are arranged just on the back of the “IC 17”. Also in the case of the substrate 10A of FIGS. 14 and 15, a large number of electronic components 21 such as capacitors are arranged on the back side of the “IC5”.
In such a case, it is very preferable that the identification information 25 of the dense electronic components 21 is represented in the form of the second identification information as described above.

<6. Substrate management number of substrate of embodiment>

Next, the substrate management number 50 will be described.
As described above, the board management number 50A in the first description format is written on the board 10A shown in FIGS. On the other hand, the substrate management number 50B of the second description format is described on the substrate 10B of FIGS.
The board management number is usually written in the first description format with its constituent characters in a single horizontal character string, but in this case, if there is not enough description area on the board, each character must be made extremely small Don't be.
For example, in the examples of FIGS. 14, 15, 21, and 23B, a description area having a height that can accommodate a relatively long and large character size can be secured in addition to the mounting area J. The management number 50A can be described. By using a sufficiently large character size and a horizontal character string, it is easy to read the entire board management number. However, in the example of FIGS. 16 and 17, such a horizontally long description area cannot be secured in addition to the mounting area J.

  Therefore, in the case of FIG. 16 and FIG. 17, the board management number 50B written in two rows in which the constituent characters are divided into the management number constituent parts 51 and 52 into two rows is described. In this way, even if a horizontally long region cannot be secured, the board management number 50B can be described with a sufficient character size.

In recent years, a large number of electronic components are often densely arranged on the substrate 10. The wiring pattern is also complicated. On the other hand, the plane size of the board itself cannot be increased unnecessarily for the convenience of mounting on the bullet ball game machine 100 or the spinning cylinder game machine 200.
Under these circumstances, the mounting area J occupies most of the area on the board, and it is difficult to secure an area for describing the board management number 50. When the description area is not sufficient, the description is made so that the character size is reduced and packed. However, in this case, the visibility of the board management number 50 is remarkably deteriorated.
Therefore, the substrate management number 50 having a sufficiently large size can be expressed by describing in the second description format according to the description region circumstances of the substrate 10 without necessarily focusing on the first description format.

As another example of the second description format, as shown in the example of FIG. 23A, the constituent characters of the board management number are divided into a plurality of management number constituent parts 51, 52. 10 may be described in spaced apart positions on the screen.
In the case of FIG. 23A, in addition to the mounting area J, a horizontally long area sufficient to describe all of the characters as the board management number 50 or an area that can be represented in two columns cannot be secured. Even in such a case, the board management number 50 can be expressed with a sufficiently large character size by separating the two management number components 51 and 52 of “FJ” and “AB1231C” as shown in the figure.

That is, if each column is written at the same position (neighborhood) in two-column writing as shown in FIGS. 16 and 17, the recognition of all characters of the board management number 50 can be improved.
On the other hand, the separation description as shown in FIG. 23A is preferable in that it realizes the description of the substrate management number with good visibility when the area that can be represented in two columns cannot be secured.
FIG. 23B shows a case where a horizontally long region describing the board management number 50A in the first description format can be secured by arranging the connectors “CN21” and “CN22” along the left side of the end side 12. As described above, if the board management number 50A in the first description format can be described in a sufficient size, the description in the first description format may be applied with priority over the second description format on the substrate surface. Conceivable.

Here, the expansion of the mounting area J, that is, the reduction of the area where the board management number 50 can be written is also affected by the above-described idea of the identification information 25.
For example, when the identification information 25 as the second identification information is written away from the electronic component 21, the number of cases where the identification information 25 is written at the peripheral edge of the substrate 10 also increases.
Further, when the identification information group 27 is provided, a relatively wide area is occupied, which leads to the expansion of the mounting area J. In particular, since the identification information group 27 is often provided in the vicinity of the end portion where the electronic components 21 are not so dense, the area where the board management number 50 can be written tends to be small.
It is also necessary to consider that the lead line 33 is not divided by the board management number 50.
Further, as shown in FIG. 21, a lead line 33 is provided from the electronic component 21 (electronic component group 22) on the substrate 10 toward the end of the substrate, that is, toward one of the end sides 11, 12, 13, and 14. Pointing to the identification information 25 (identification information group 27) also promotes occupation of the vicinity of the substrate edge by the identification information 25 (identification information group 27).
Further, by using the corresponding markers 34 and 35, the identification information 25 and the identification information group 27 are more easily displayed on the peripheral portion of the substrate 10.
Further, when there is an electronic component 21S mounted in an oblique direction, the peripheral wiring, identification information 25, and identification information group 27 can easily approach the edge of the substrate (for example, see FIG. 16).

For these reasons, the area in which the board management number 50 cannot be written is expanded as the mounting area J. In such a case, the board management number 50 can be described with good visibility by using the board management number 50B in the second description format. In other words, particularly when the identification information 25 (identification information group 27) as the second identification information is provided, the effect of using the board management number 50B in the second description format becomes remarkable.
That is, the relationship between the identification information 25 as the second identification information and the electronic component 21 is clarified, and the board management number 50B can be described with a sufficient character size compared to the identification information 25 using the second description format. Thus, the visibility of both the board management number 50 and the identification information 25 can be enhanced.

Specifically, the following substrates (a), (b) and (c) are desirable.
(A) A substrate having the board management number 50B in the second description format and the identification information 25 as the second identification information written away from the electronic component 21 as in the embodiment.
When the second identification information expressed separately from the electronic component 21 is expressed in correspondence with the electronic component 21 by the leader line 33, the corresponding markers 34, 35, etc., the board is widely occupied, and the horizontal row of substrate management numbers There are many cases that cannot be described. By using the board management number 50B in the second description format, the board management number can be described with a sufficient size.
Further, the relationship between the second identification information and the electronic component 21 is clarified, and the board management number can be described with a sufficient character size compared to the identification information 25 using the board management number 50B in the second description format. The visibility of both the substrate management number 50 and the identification information 25 can be improved.

(B) A substrate having the substrate management number 50B in the second description format and the identification information group 27 as the second identification information as in the embodiment.
The identification information group 27 is often described near the periphery of the substrate. In other words, the element is often dense in the central portion. As a result, there is no room for the substrate management number 50 to be written near the periphery of the substrate. In this case, since the board management number 50B having a large character size can be described in the second description format, both the visibility of the identification information 25 and the visibility of the board management number 50 can be compatible.

(C) As in the embodiment, the board having the board management number 50B in the second description format and the second identification information indicated by the lead line 33 drawn from the electronic component 21 toward the board edge.
The fact that the second identification information in the direction of the board edge is associated with the electronic component 21 by the lead line 33 facilitates the identification information 25 being written on the peripheral edge of the board. For this reason, it is easy to eliminate the margin for describing the substrate management number 50 in the vicinity of the peripheral edge of the substrate, but in this case, a large character size substrate management number 50B can be described in the second description format. As a result, both the visibility of the identification information 25 and the visibility of the board management number 50 can be achieved.

The board management number 50B in the second description format shown in each example of FIGS. 16, 17, 21, and 23 includes a management number component 51 as manufacturer information and a management number component 52 as other information. Are described in different rows or spaced apart.
When the two-column notation or the separation notation is used, the recognition of the substrate management number 50B of the viewer is not hindered by dividing the manufacturer information portion and other information portions (date, model-specific code, etc.). In other words, the second description format can be a description that allows manufacturer information, date, model-specific code, and the like to be easily recognized.

Further, the management number component 51 as manufacturer information and the management number component 52 as other information may be described by different methods.
The management number component 51 as manufacturer information is a character common to each board 10. On the other hand, the management number component 52 as other information may be different for each substrate. Therefore, by describing with different construction methods, it is possible to improve the efficiency of describing the common character portion.
As a construction method for describing the substrate management number 50, there are a printing method, a photographic method, and a direct drawing method (for example, laser drawing).
For example, the manufacturer information “FJ” or “FJ +” may be printed using the printing method, and the other information “AB1231C” may be directly drawn.
It is also conceivable that a master film is used for the manufacturer information portion common to each model, and a method that does not require a master film is used for the information portion that is different for each model.

In the bullet ball game machine 100 and the spinning cylinder game machine 200, a large number of boards 10 are mounted, but it is not necessary that all the boards 10 have the board management number 50B in the second description format. The board 10 having the board management number 50A in the first description format and the board 20 having the board management number 50B in the second description format may be used depending on the description area of each substrate 10.
Thereby, it is possible to realize easy-to-see board management number descriptions according to the area circumstances of each board 10.
It is also conceivable that a board management number 50A in the first description format is used for a board having a large substrate area, and a board management number 50B in the second description format is used for a board having a small substrate area.

Further, the first and second description formats may be properly used for the first main surface 10x and the second main surface 10y in one substrate 10.
For example, FIG. 14 and FIG. 15 show examples in which the first management format 50A is described on the first main surface 10x and the second main surface 10y. A substrate 10 on which 50A is described and the substrate management number 50B of the second description format is described on the other side is also assumed. In particular, the first main surface 10x and the second main surface 10y are different in the state of the description of the identification information 25 (identification information group 27), so that the situation of the area where the board management number 50 can be described tends to be different. Therefore, by properly using the board management numbers 50A and 50B on the front and back, both can clearly describe the board management number.

In each example shown, the board management number 50 is in either the first description format or the second description format, but in both cases, the characters constituting the board management number 50 are on the first end side (end side 12) side. It is written on the substrate 10 in a state below the characters.
Such a substrate 10 is attached to the ball game machine 100 or the revolving game machine 200 in such a direction that the first end side (end side 12) is the lower end.
For example, in FIG. 20C, it is assumed that the substrates 10-1, 10-2, and 10-3 are attached with the end sides 12 facing downward. The board management number 50B in the two-column notation is used for the board 10-1, the board management number 50B in which the management number components 51 and 52 are separated, and the board 10-3 is the board management shown in the first description format. The number 50A shows an example in which each is indicated. For any of the substrates 10, the viewer can open a normal posture, for example, a posture facing the back of the ball game machine 100 (see, for example, FIG. 31), or open the front panel 202 of the spinning game machine 200. The board management number 50 in which the character string is normally written horizontally can be confirmed in a posture facing the back of the front panel 202 (see FIG. 6) and the inside of the main body case (see FIG. 7). That is, the direction of the character as the board management number is not landscape or upside down. Therefore, the board management number 50 is very easy to read.

As described above, with regard to the identification information 25, regarding the directionality of the character, the vertical direction of the character is set as the first end side reference or the second end side reference, thereby improving the visibility. This also considers the correspondence with each electronic component 21, but it is not necessary to consider the correspondence with the individual electronic component 21 regarding the board management number 50. The substrate 10 is required to have good visibility in a state where it is attached to the bullet ball game machine 100 or the spinning cylinder game machine 200 to the last. Therefore, if the substrate 10 is attached in such a direction that the first end side (end side 12) is the lower end, the character as the substrate management number 50 may be described on the basis of the first end side. .
Therefore, when the board 10 is attached to the gaming machine with the direction in which the first edge is downward, the board management number 50 is described on the basis of the first edge, and the identification information 25 corresponds to the electronic component 21. It is appropriate to be described on the basis of the first end side or the second end side. That is, in any case, the vertical direction of the characters forming the identification information is not opposite to the vertical direction of the gaming machine body.
As a result, the visibility of each identification information 25, the visibility of the board management number 50, and the identification information 25 and the electronic are improved when the board 10 is mounted on the ball game machine 100 or the spinning machine 200. The comprehension of the correspondence of the component 21 can be realized together.

The character string direction of the identification information 25 is parallel to the long side of the electronic component 21 so that the correspondence between the electronic component 21 and the identification information 25 can be easily grasped. As shown in FIGS. 16, 17, and 23A, even when there is an electronic component 21S that is mounted in an oblique direction that is not parallel to the respective edges (11 to 14) of the substrate, identification information 25 corresponding to the electronic component 21S is also present. The correspondence relationship between the electronic component 21S and the identification information 25 is clarified as a direction parallel to the long side direction of the electronic component 21S (that is, non-parallel to the end sides (11 to 14)).
Also in these cases, the board management number 50 is described in a state parallel to the edges 11 and 12 of the board. Thereby, the visibility of each of the identification information 25 and the board management number 50 can be improved. That is, the identification information 25, 25S has a clear relationship with the electronic component 21, and the board management number 50 is a board with a sufficient character size compared to the identification information using the first or second description format. Since the management number can be described, the visibility of both the board management number and the identification information can be improved.

<7. Arrangement of board management number and relation between board case and cover>

As described so far, in the present embodiment, the substrate management number 50 is devised so as to be clearly described in a sufficient size on the substrate 10. Hereinafter, various examples of the arrangement of the board management number 50 will be described.

First, the substrate 10 is mounted on the back or inside of the gaming machine. At that time, the substrate 10 is not exposed and fixed with screws or the like, but is mounted in a state of being stored in the substrate case.
FIG. 24 is a perspective view showing a state in which the substrate 10 is stored in the substrate case 70, and FIG. 25A is a plan view thereof.
The substrate case 70 has a housing formed of a transparent or translucent resin. The housing of the substrate case 70 is formed by joining the upper surface portion 70A and the base portion 70B. Various types of electronic components 21 are mounted inside the housing, and the board 10 on which the board management number 50 is written is stored.
In the following description and illustration, the board management number 50 is an example in which the board management number 50A in the first description format is described, but both are set to the board management number 50B in the second description format. It may be.

The substrate case 70 is formed of a transparent or semi-transparent resin so that the inner substrate 10 can be visually recognized. Accordingly, the board management number 50, each electronic component 21, the identification information 25 (not shown), and the like are also visible from the outside of the board case 70.
Holes 72 are formed at various places in the substrate case 70 for the purpose of heat dissipation or the like. For example, an example is shown in which a large number of holes 72 as small holes are formed on the upper surface of the case, and holes 72 are formed on the case edge from the upper surface to the side surface. Of course, the position, shape, size, and number in the case of providing the hole 72 can be considered variously.
For the sake of explanation, the “hole portion 72” refers to a relatively small opening rather than having an opening space larger than the area described by all the characters of the board management number 50. An opening of a housing having an opening space larger than the area described by the substrate management number 50 is referred to as an opening 78A described later to be distinguished.

Further, the board case 70 is appropriately formed in a required shape according to the convenience of attachment to the gaming machine, the shape of the board 10, the type of parts to be mounted, the parts arrangement, and the like. As in the example of FIGS. 24 and 25A, a beveled portion 73 on the housing is formed by appropriately forming slopes, wall surfaces, etc., and reinforcing ribs 74 are formed at predetermined positions in the case. Is done.
Further, a screw support 75 (including a thickness changing portion around the support) for inserting a screw for joining the upper surface 70A and the base 70B is also provided at a required location.
Although not shown in FIGS. 24 and 25, the housing of the substrate case 70 has a notch or a large opening (a notch 78A or notch 78B in FIGS. 28 and 29) that exposes a part of the substrate 10. ) May be provided.
Further, the board type, the model name of the gaming machine, the setting information, and the like may be printed on the upper surface side of the board case 70 (printing unit 76 in FIGS. 28 and 29).
In particular, when the substrate 10 is the main control substrate 150, 240 or the like, a case where a sealing seal (sealing seal 77 in FIG. 29) is attached to prevent the substrate case 70 from being opened unnecessarily, or the case housing is attached by a caulking mechanism. In some cases, the substrate 10 cannot be taken out without being destroyed.

The connector CN attached to the substrate 10 needs to be exposed from the substrate case 70 in order to connect to another substrate or the like, that is, to connect the harness 63 or the flexible substrate. Therefore, a part opening 79 is formed in the case housing so that the connector CN is exposed from the board case 70, and the connector CN is exposed.
FIG. 25B shows an enlarged connector arrangement portion. The connector CN attached to the substrate 10 protrudes from a component opening 79 formed in the substrate case 70. In order to allow the connector CN to protrude in this way, the upper surface of the housing of the substrate case 70 is formed so that the portion corresponding to the connector position has a low height.
The connector CN to be mounted on the board 10 is, for example, a pin side housing, and a jack side housing 62 to which a harness 63 is attached is connected (of course, the pin side and the jack side may be reversed). Accordingly, the harness 63 is led out from the substrate 10 in the substrate case 70 as shown in FIG. 24 and is electrically connected to the other substrate 10 and the like.

In the ball and ball game machine 100 and the spinning cylinder game machine 200 of the present embodiment, each board 10 is mounted as shown in FIG. That is, the plurality of substrates 10 are electrically connected by the harness 63 connected to each other connector CN.
Below, arrangement | positioning of the board | substrate management number 50 in the board | substrate 10 is demonstrated.
First, the positional relationship between the board management number 50 and the connector CN will be described with reference to FIGS.

FIG. 26 shows an example in which the board management number 50 is written at a position near an end side different from the end side where the connector CN is arranged.
In the following description, as described above, it is assumed that the substrate 10 is attached to the gaming machine in a posture state in which the end 12 side is downward (the arrow DR1 is attached as in FIG. 20).
FIG. 26A is an example of the substrate 10 in which the end sides 11 and 12 are in the longitudinal direction. The connector CN101 is attached in the vicinity of the end side 14 with its long side extending along the end side 14 of the substrate 10. In addition, the connector CN102 is attached in the vicinity of the end side 13 with its long side extending along the end side 13 of the substrate 10. The position where the board management number 50 is written is in the vicinity of the end side 11 along the end side 11.
FIG. 26B is also an example of the substrate 10 in which the end sides 11 and 12 are in the longitudinal direction. Two connectors CN103 and CN104 are attached in the vicinity of the end side 11 with their long sides along the end side 11 of the substrate 10. The connector CN 105 is attached in the vicinity of the end side 13 with its long side extending along the end side 13. The position where the board management number 50 is written is in the vicinity of the end side 12 along the end side 12.
FIG. 26C is an example of the substrate 10 in which the end sides 11 and 12 are in the short direction. Two connectors CN106 and CN107 are attached in the vicinity of the end side 14 with their long sides along the end side 14 of the substrate 10. The connector CN 108 is attached in the vicinity of the end side 13 with its long side extending along the end side 13. The position where the board management number 50 is written is in the vicinity of the end side 11 along the end side 11.

In any of the examples of FIGS. 26A, 26B, and 26C, the board 10 is attached to the connector so that the long side of the connector CN is along the edge of the board, and the position indicated by the board management number 50 is the length of the connector CN. The position is in the vicinity of the substrate edge different from the substrate edge along which the edge is along.
As can be seen from each drawing, the board management number 50 is written on the end side different from the end side where the connector CN is arranged so that the board management number 50 is not made invisible by the harness 63 derived from the connector CN. can do. Further, in any case, even when viewed from the front in the direction directly above the substrate surface, it is not invisible.

In addition, the harness 63 is not necessarily arranged straight from the end side to the outside of the board (in a direction perpendicular to the end side) while being attached to the gaming machine. It is arranged so as to face the substrate. For example, FIG. 26B shows an example in which the harness 63 from the connectors CN103 and CN104 goes to the right side, and FIG. 26C shows an example in which the harness 63 from the connector 108 goes down.
However, regardless of the direction in which the harness 63 is directed, if the board management number 50 is described in the vicinity of an edge different from the edge on which the connector CN is disposed, the board management number 50 is assigned to the harness 63. There is almost no state where it is covered and invisible.
Further, when the harness 63 has a large margin, the harness 63 may be bent and cover the center side of the board somewhat from the connector CN. However, the board management number 50 is described near the edge different from the connector CN. The board management number 50 can be prevented from becoming invisible.

In order to make the board management number 50 easy to see without turning upside down with the board 10 attached to the gaming machine as described above, the board management number 50 is set to the edge 11 or 12 (that is, to the gaming machine). It is preferable that the edge 12 is written along the edge that is horizontal in the attached state, and the edge 12 is the lower side of the character. Therefore, when the connector CN is not arranged on either of the end sides 11 and 12 as shown in FIGS. 26A and 26C, the position where the board management number 50 is written may be in the vicinity of either of the end sides 11 and 12.
As shown in FIG. 26B, when the connector CN (CN103, CN104) is arranged on the end side 11, the position of the board management number 50 may be set near the other end side 12 in the horizontal direction.

FIG. 27 is an example in which the board management number 50 is written in the vicinity of the same edge as the connector CN.
FIG. 27A is an example of the substrate 10 in which the end sides 11 and 12 are in the longitudinal direction. Connectors CN 201 and CN 202 are attached in the vicinity of the end side 11 with their long sides along the end side 11. The connector CN 203 is attached in the vicinity of the end side 13 with its long side extending along the end side 13. The description position of the board management number 50 is in the vicinity of the connector CN provided along the end side 11 and is closer to the center side of the board.
FIG. 27B is also an example of the substrate 10 in which the end sides 11 and 12 are in the longitudinal direction. The connector CN 204 is attached in the vicinity of the end side 11 with its long side extending along the end side 11. The connector CN 205 is attached in the vicinity of the end side 12 with its long side extending along the end side 12. The description position of the board management number 50 is in the vicinity of the connector CN provided along the end side 12 and is closer to the center of the board.

As shown in FIGS. 27A and 27B, the position where the board management number 50 is described may be a position closer to the center of the board than the position where the connector CN is arranged.
Since the harness 63 is arranged so as to go from the connector CN toward the peripheral board or the like, the position closer to the center of the board than the connector arrangement position is a position that is hardly covered by the conductive wire material. Therefore, the board management number 50 is hardly invisible by the harness 63.

FIG. 27C is an example of the substrate 10 in which the end sides 11 and 12 are in the longitudinal direction. The connector CN 206 is attached in the vicinity of the end side 11 with its long side along the end side 11. Further, the connector CN 207 is attached in the vicinity of the end side 12 with its long side extending along the end side 12. The position where the board management number 50 is described is such that the board management number 50 is arranged side by side on the connector CN provided along the edge 11.
FIG. 27D is an example of the substrate 10 in which the end sides 11 and 12 are in the short direction. The connector CN 208 is attached in the vicinity of the end side 13 with its long side extending along the end side 13. The connector CN209 is attached in the vicinity of the end side 12 with its long side extending along the end side 12. The position where the board management number 50 is described is such that the board management number 50 is arranged side by side on the connector CN provided along the edge 12.

As shown in FIGS. 27C and 27D, the connector CN is attached so that the long side is along the board edge, and the position of the board management number 50 is near the board edge along the long side of the connector CN. Therefore, the position may be shifted from the connector position in the line direction of the board edge (arrow DL direction).
By arranging in such a shifted state, even when the board management number 50 is written in the vicinity of the same edge as the connector CN, the harness 63 can prevent the board management number 50 from becoming invisible. .

  In addition, it is desirable to set the position where the board management number 50 is set in the vicinity of the edge 11 or 12 that is in the horizontal direction in the mounted state. However, as shown in FIGS. When the connector CN is arranged, it is useful to set the description position of the board management number 50 along the same end side as the connector CN by the above method.

As in the examples of FIGS. 26 and 27 described above, the gaming machine according to the embodiment has a first electronic circuit board (as shown in FIGS. 26 and 27) on which the board management number 50 is written and the connector CN is attached. A gaming machine on which a plurality of electronic circuit boards 10 including a board 10) are mounted. The first electronic circuit board is not made invisible by the conductive wire in a state where it is mounted on the gaming machine and electrically connected to the other electronic circuit board by the conductive wire (harness 63) via the connector CN. The board management number 50 is written at the position.
Thereby, the visual recognition of the board management number 50 is not hindered by the conductive wire from the connector CN (for example, a cable, a cable harness, a flexible board, etc.), and the board management number 50 can be easily confirmed.
The arrangement relationship between the connector CN and the board management number 50 described with reference to FIGS. 26 and 27 is suitable even when the board 10 is attached to the gaming machine without being stored in the board case 70. Needless to say.

Next, the arrangement of the board management number 50 on the board 10 and the positional relationship of the board case 70 will be described.
The substrate case 70 is formed of a transparent or translucent resin as described above, but even in that case, the visibility of the substrate management number 50 may be reduced. For example, even if the substrate case 70 is transparent or translucent, there is a region where the visibility is lowered due to the shape, opening, or the like of the substrate case 70. Therefore, in the embodiment, the visibility of the board management number 50 is improved by placing the invisibility reduced portion of the board case housing in front of the board management number 50.

28 and 29, the outline of the board 10, the connector CN, and the board management number 50 are indicated by solid lines, and the board case 70 is indicated by broken lines.
In each figure, the peripheral part of the connector CN is a part where the upper surface of the substrate case is set low and the connector CN is exposed as shown in FIG. 25B.

FIG. 28A shows a state in which the hole 72 of the substrate case 70, the bent portion 73 of the case housing, or the printing unit 76 is not positioned in front of the substrate management number 50. The printing unit 76 is actually an area in which the type, specification, board specification, and other information of the gaming machine is printed on the case housing, and is indicated by hatching in the drawing.
In addition, the front of the board | substrate management number 50 means the front direction of a board | substrate surface. This is a direction toward a position where the board management number 50 is normally visually recognized for a person who inspects the gaming machine.
FIG. 28B shows a state in which the rib 74, the screw support 756, or the bent portion 73 of the substrate case 70 is not positioned in front of the substrate management number 50.
FIG. 28C shows a state in which an opening 78 </ b> A formed in the substrate case 70 is located in front of the entire substrate management number 50. That is, the entire character string of the board management number 50 can be seen through the opening 50. In addition, in this example, the hole portion 72 and the bent portion 73 of the substrate case 70 are not located in front of the substrate management number 50.
FIG. 28D shows a state in which a notch 78B formed in the substrate case 70 is located in front of the entire substrate management number 50. FIG. That is, the entire character string of the board management number 50 can be seen through the notch 78. In addition, the printed part 76 and the bent part 73 of the board case 70 are not located in front of the board management number 50.

FIG. 29A shows a state in which an opening 78 </ b> A formed in the substrate case 70 is located in front of the entire substrate management number 50. That is, the entire character string of the board management number 50 can be seen through the opening 50. In addition, in the front of the substrate management number 50, the hole 72, the bent portion 73, the rib 74, the screw strut portion 75, the printing portion 76, and the seal seal 77 of the substrate case 70 are not located. In the figure, the seal seal 77 is shown as a filled portion. The seal seal 77 is attached so as to extend from the upper surface to the side surface of the substrate case 70, for example.
Figure 29B, in front of the entire substrate control number 50, the hole portion 72 and the bent portion 73 of the base plate case 70, the ribs 74, the threaded post portion 75, the printing unit 76, in the example seal seal 77 is not located either is there.

The positional relationship between the substrate management number 50 and the substrate case 70 is summarized as follows.
In both examples of FIGS. 28 and 29, the invisibility-reduced portion of the housing of the substrate case 70 is located in front of the substrate management number 50.
One of the non-visibility reduction portions is a non-step portion in the substrate case 70. Visibility is ensured by preventing the front surface of the substrate management number 50 from becoming a stepped portion.

Specifically, the non-step portion is a flat portion having a uniform plate thickness in the housing of the substrate case 70. The example of FIG. 28A, FIG. 28B, and FIG. 29B corresponds to this, and the front surface of the board | substrate management number 50 is a plane part with uniform board thickness.
If the plate portion has a uniform plate thickness, the light transmission is uniform, and the substrate management number 50 is not hindered from being viewed through regions having different refractive indexes and transmittances.

Further, the non-step portion is considered to be a planar portion where the hole portion 72 does not exist in the housing of the substrate case 70. For example, FIG. 28A, FIG. 28B, FIG. 29A, and FIG.
In a region where a step due to the hole 72 is generated, the space due to the hole 72 and the case housing are mixed in front of the board management number, thereby hindering visibility. Improve sexiness.

Further, the non-step portion may be a flat portion where the bent portion 73 does not exist in the housing of the substrate case 70. 28A to 28D, 29A, and 29B, the front surface of the substrate management number 50 is not the bent portion 73.
If the bent portion 73 exists as a bent portion, a concavo-convex portion, a hole, a rib, or a thickness variation portion of the case housing, the refractive index and transmittance of light are not constant in front of the board management number, and visibility is reduced. . Therefore, visibility is improved by preventing the bent portion 73 from being in front of the substrate management number 50.

Further, the non-step portion may be a space portion formed by the opening 78A or the cutout portion 78B of the housing of the substrate case 70. 28C, 28D, and 29A are examples of this.
In these cases, the front of the board management number 50 is all space. Therefore, the visibility is improved because the visibility of the substrate case 70 is not reduced by the housing resin.

The condition that the non-reduced portion of the substrate case 70 is not limited to the non-stepped portion as described above is also appropriate as a portion that is not printed on the substrate case housing.
In FIG. 28A, FIG. 28D, FIG. 29A, and FIG. 29B, the printing unit 76 is provided, but the board management number 50 is described at a position where the printing unit 76 does not come to the front.
This is because the printed area has a very low visibility inside the case.
FIG. 28A, FIG. 28D, FIG. 29A, and FIG. 29B are also examples in which the front face of the board management number 50 is other than the printing unit 76 and is a non-stepped part. Visibility is improved by the substrate management number 50 being described at a position where the non-step portion other than the printing portion is the front.

Furthermore, the condition that the non-visibility reduction portion of the substrate case 70 is a portion other than the region where the seal seal 77 is attached to the substrate case housing is also appropriate.
29A and 29B are examples in which the front surface of the board management number 50 is outside the area where the seal seal 77 is attached. These are also examples in which the front surface of the board management number 50 is a non-stepped portion other than the attachment region of the seal seal 77 and other than the printing portion 76.
Since the inside of the region to which the seal seal 77 is attached cannot be visually recognized, it is inappropriate to be positioned in front of the board management number 50. And it is suitable for a visibility improvement that a non-visibility fall part is a non-step part other than the attachment area | region of the sealing seal | sticker 77 with respect to a substrate case housing | casing. It is also appropriate that the invisibility-reduced portion is a portion that is not the printing unit 76 other than the region where the seal seal 77 is attached to the substrate case housing.

Next, the arrangement of the board management number 50 on the board 10 and the positional relationship between the board case 70 and the cover body 80 will be described.
In gaming machines, electronic circuit boards are often mounted in gaming machines while being stored in board cases 70 for reasons such as protection and prevention of unauthorized tampering, but board protection and board 10 (board case 70) are also included. In many cases, a cover body is provided on the substrate case 70 for the purpose of preventing fraud by removing it.
For example, FIG. 30 shows an example of the cover body 80 attached to the back surface of the gaming machine, and FIG. 31 shows the state of the back surface of the gaming machine with the cover body 80 attached.
In FIG. 31, the outline of the board 10, the connector CN, and the harness 63 are shown by solid lines, the board case 70 is shown by broken lines, and the cover body 80 is shown by a dashed line.
FIG. 31 shows an example in which board cases 70a to 70e respectively containing boards 10a to 10e are attached to the gaming machine. The boards 10 in each board case 70 are electrically connected by a harness 63 from the connector CN.
And the cover body 80 is attached with respect to these board | substrate cases 70 so that a part of the upper direction (front side of the board | substrate 10) may be covered.

The cover body 80 is formed as a transparent or translucent resin, for example, as shown in FIG. A rotation shaft 81 is formed on one side of the cover body 80, and a fixing portion 82 is formed at a required location.
The cover body 80 can be opened and closed on the back side of the gaming machine by inserting a rotating shaft 81 through a shaft support (not shown) provided on the back side of the gaming machine. Further, in the closed state, the fixing pin attached to the fixing portion 82 is fixed to the back surface in the state shown in FIG. 31 by fitting with a fixing mechanism (not shown) on the back surface portion of the gaming machine.
The cover body 80 has an opening 83 for heat dissipation or the like at a required location. In this example, the opening 83 is a hole larger than the entire character string as the board management number 50.

  In the example of FIG. 31, the cover body 80 is not configured to cover all of the substrate cases 70 a to 70 e, and a part of the substrate cases 70 d and 70 e is exposed from the cover body 80. Yes. Of course, the cover body 80 may cover the entire substrate case 70 on the back surface. What part the cover body 80 covers should just be set suitably according to a model, board | substrate arrangement | positioning, etc.

The description position of the board management number 50 will be described as a positional relation including the cover body 80.
In the embodiment, all or a part of the boards 10 (first electronic circuit boards) are arranged so that the board management number 50 is not identifiable by the cover body 80 in the positional relationship with the cover body 80. ing. That is, in the embodiment, considering that the visibility of the board management number 50 may be slightly lowered by the cover body 80, the board management number is devised by devising the positional relationship between the board management number 50 and the cover body 70. The visibility of 50 is improved.
A specific example will be described with reference to FIG. In FIG. 31, the five substrates 10a to 10e are examples in which various methods for improving the visibility of the substrate management number 50 are employed. The visibility improving methods (1) to (5) will be described below, but as a gaming machine, the visibility improvement may be achieved by any method for each substrate 10. Of course, it is not necessary to mount all of the boards on which the following five types of methods (1) to (5) are adopted in the gaming machine.

(1) A method in which the front surface of the substrate management number 50 is set to a position where the cover body 80 does not exist.
The front surface of the substrate management number 50 of the substrates 10d and 10e is not covered by the cover body 80.
Therefore, in the gaming machine having the board 10d or 10e, all or part of the electronic circuit board 10 is housed in the transparent or semi-transparent board case 70, and further, the cover body 80 with respect to a part of the board case 70. Is attached to the board case 70 in a state in which the board management number 50 described on the board surface is in a position where the cover body 80 does not exist. It has a circuit board.
In the case of a gaming machine having the cover body 80, the visibility of the board management number 50 may be slightly reduced by the cover body. Therefore, the visibility is improved by making the cover body 80 not present in front of the board management number 50.
The board 10a is also housed and attached to the board case 70 in a state where the front of the board management number 50 is located at a position where the cover body 80 does not exist on the front due to the presence of the opening 83. It can be said that.

(2) A method in which the front face of the board management number 50 is a position where the cover body 80 does not exist and the invisibility-reduced portion of the board case 70 corresponds to the boards 10d, 10e, and 10a. The front surface of the board management number 50 is not covered by the cover body 80, and is a non-visibility reduction part of the board cases 70d, 70e, 70a. Specifically, the front surface of the substrate management number 50 is the non-step portion (not the hole 72, the bent portion 73, or the like, or the opening space) of the substrate case 70, and the substrate 10e is the substrate management number 50. The front side is a notch 78B.
Therefore, the gaming machine having the board 10d, 10e, or 10a is stored in the board case 70 in a state where the non-visibility reduction portion in the housing of the board case 70 is located in front of the board management number 50 described on the board surface. In addition, the electronic circuit board is attached in a state where the cover body 80 does not exist in front of the board management number 50.
The substrate case 70 is transparent or semi-transparent, but there is a region where the visibility is lowered due to the shape or printing of the substrate case 70. Therefore, the visibility of the board management number is improved by placing the invisibility reduced portion of the board case housing in front of the board management number.

(3) Method of making the substrate management number 50 visible without using either the cover body 80 or the substrate case 70 Substrates 10e and 10a are applicable.
In the substrate 10e, the notch 78B of the substrate case 70e is the front of the substrate management number 50 as described above.
The substrate 10a (substrate case 70a) is located in a range where all parts are covered with the cover body 80, but the front surface of the substrate management number 50 is the opening 78A of the substrate case 70a. The opening 83 is formed.
Therefore, in the gaming machine having the board 10e or 10a, the space portion formed by the notch 78B (or the opening 78A) of the housing of the board case 70 is located in front of the board management number 50 described on the board surface. In this state, the electronic circuit board is mounted in a state where the cover body 80 is not located in front of the board management number 50 after being housed in the board case 70.

In this case, the board management number 50 is not covered by the board case 70 or the cover body 80, and the visibility is the best.
In practice, it may be difficult to find the board management number 50 on the board 10 on which a large number of electronic components 21 are arranged. In the case of this method, since the position of the substrate management number 50 becomes clear at a glance by the opening 78A, the notch 78B, and the opening 83, there is also an advantage that the efficiency of visual inspection can be improved.

  In the case of (1), (2), and (3) above, the visibility of the substrate management number 50 is ensured even if the cover body 80 is opaque. Therefore, when any one of the methods (1), (2), and (3) is used for all the substrates 10 on which the substrate management number 50 is described, the cover body 80 may be an opaque member.

(4) Although the front surface of the board management number 50 is covered with the cover body 80, the method of setting the non-visibility reduction part of the cover body 80 and the non-visibility reduction part of the board case 70 to the boards 10b and 10c.
The substrates 10 b and 10 c (substrate cases 70 b and 70 c) are located within a range where all of them are covered with the cover body 80.
The front surface of the substrate management number 50 of the substrate 10b is a non-stepped portion of the substrate case 70a.
The front surface of the substrate management number 50 of the substrate 10c is an opening 78A of the substrate case 70c.
Therefore, in the gaming machine having any one of the boards 10b and 10c, all or part of the electronic circuit board 10 is housed in the transparent or semi-transparent board case 70, and further, with respect to part or all of the board case 70. A gaming machine to which a transparent or translucent cover body 80 is attached so as to cover it, and a non-visibility reduction portion in the housing of the substrate case 70 is located in front of the substrate management number 50 described on the substrate surface. In this state, the electronic circuit board is mounted in a state where the invisibility-reduced portion of the cover body is located in front of the board management number 50 after being housed in the board case 70.

In this case, the front of the board management number 50 is in a state where the non-visibility reduction part of the board case 70 and the non-visibility reduction part of the cover body 80 are located, and the visibility can be improved.
Here, the non-visibility reduction portion of the cover body 80 may be considered in the same manner as that of the substrate case 70. For example, since a step portion generated as a hole portion, a bent portion, a rib, a screw support portion, a printing portion, or a seal attachment portion is a visibility-decreasing portion, it can be considered as a portion other than those.
In the case of the example of FIG. 31, the front of the board management number 50 of the boards 10 b and 10 c is a plane part where the plate pressure in the cover body 80 is uniform, and thus it can be said that the invisibility reduced part is in front.

(5) Method for enabling visual recognition through only the cover body 80 within the range of the cover body 80 corresponds to the substrate 10c.
In the substrate 10c, the space defined by the opening 78A of the substrate case 70 is located in front of the substrate management number 50 as described above.
Therefore, in the gaming machine having the board 10c, all or part of the electronic circuit board is housed in the board case 70, and further, a transparent or translucent cover body 80 so as to cover part or all of the board case 70. In which the space formed by the opening 78A (or the notch 78B) of the housing of the substrate case 70 is located in front of the substrate management number 50 described on the substrate surface. Then, the electronic circuit board is mounted in a state where the invisibility-reduced portion of the cover body 80 is located in front of the board management number 50 after being housed in the board case 70.
In this case, the front of the board management number is in a state where only the non-visibility reduction portion of the cover body is located, and the visibility can be improved.

<8. Summary and Modification>

According to the present embodiment, it is possible to improve the visibility of the board management number 50 of the electronic circuit board 10 in a state where the board management number 50 is mounted on the bullet ball game machine 100 and the spinning cylinder game machine 200. For example, the inspector can read the character of the board management number 50 in a normal posture in a state of facing the back of the gaming machine or the inner surface (not upside down), and is not hidden by the harness 63. Further, the visibility is not hindered by the substrate case 70 or the cover body 80. As a result, the board management number 50 can be confirmed and easily and accurately, which is very effective in preventing fraud.
Note that the board management number 50 is not always written on all boards mounted on the gaming machine. There is also an electronic circuit board in which the board management number 50 is not described. In the present invention, the visibility of the substrate management number 50 is the same as that of the substrate 10 on which the substrate management number 50 is described or at least one of the substrates 10 on which the substrate management number 50 is described. Of course, the visibility should be improved by a technique.

Further, according to the present embodiment, in the electronic circuit board 10 of the ball game machine 100 and the revolving game machine 200, the board management number 50 can be clearly described with a sufficient character size, and is easy to see for the viewer. Can do.
Further, the identification information 25 of the electronic component 21 is clearly and accurately displayed on the electronic circuit board 10 of the bullet ball game machine 100 and the spinning cylinder game machine 200, so that the electronic component 21 can be easily identified.
In addition, by clearly and accurately displaying the board management number 50 and the identification information 25 of the electronic component 21 in this way, it is possible to provide a gaming machine that is excellent in anti-fraud measures.
In addition, the wiring pattern of the electronic component 21 can be easily routed on the electronic circuit board 10, and the manufacturing efficiency can be improved. This is due to the provision of the electronic component 21S mounted in an oblique direction. Furthermore, by using the board management number 50B in the second description format, the restriction for securing the description area of the board management number 50 is relaxed.
Further, the terminal arrangement of the electronic component 21 (bottom terminal type electronic component) in which a plurality of terminals are arranged on the bottom surface of the chip on the electronic circuit board 10 can be easily confirmed, which is convenient for manufacturing and inspection.

Note that the present invention is not limited to the examples given in the embodiment, and various modifications and application examples are conceivable.
For example, the board management number 50B has been described with an example of two-column notation, but notation of three or more columns is also conceivable.
In addition, although the example in which the board management number 50B is described at two positions separated by two management number components 51 and 52 has been given, it may be considered that the board management number 50B is separated into three or more management number components.

Although the identification information 25 is based on silk printing, various display colors of the identification information 25 are conceivable. Silk printing colors are diverse.
It is also conceivable that adjacent identification information 25 (identification information group 27) can be easily identified by changing the color of silk printing.
The character size may be different for each identification information 25 (identification information group 27).
As for the board management number 50, it is desirable that the character size is clearly different from that of the identification information 25 so that it can be clearly distinguished from the identification information 25. The character string as the board management number 50 may be a so-called hollow character or a color different from the identification information 25 in order to ensure clarity.

  Further, the identification information 25 of the electronic component 21 on the first main surface 10x of the substrate 10 is written on the second main surface 10y side, or the identification information 25 of the electronic component 21 on the second main surface 10y is displayed on the first main surface 10x. There may be a part as shown on the side.

The leader line 33 is indicated by a solid line in each figure, but is not limited to a solid line. For example, various lines such as a double line, a triple line,..., An n-fold line, a broken line, a dotted line, a one-dot chain line, a two-dot chain line,.
In addition to the straight line, the lead line 33 can be drawn out of a refraction line, a curve, or a combination of these.

The lines constituting the enclosure lines 31 and 32 are also various lines such as a solid line, a double line, a triple line ... n double line, a broken line, a dotted line, a one-dot chain line, a two-dot chain line ... n-dot chain line, a wavy line, etc. Can be used.
The shapes of the surrounding lines 31 and 32 may be in accordance with the electronic component 21 (electronic component group 22) and the identification information 25 (identification information group 27), and are square, rectangular, rhombus, trapezoid, parallelogram, triangle, 5 Various shapes can be used, such as polygons more than a square, shapes with various square corners with R, circles, ellipses, and irregular shapes.
The enclosure lines 31 and 32 are not limited to being provided in all the electronic components 21 (electronic component group 22) and the identification information 25 (identification information group 27) on the substrate 10. The effects described above can be obtained at least in the portion where the surrounding lines 31 and 32 are provided.

As the corresponding markers 34 and 35, alphabets, hiragana, katakana, numerals, symbols such as “@, #, *”, marks other than characters, and the like can be used.
The corresponding marker 34 on the electronic component 21 side and the corresponding marker 35 on the identification information 25 side may be the same, but may be different. That is, it is sufficient that the correspondence relationship is clear. For example, the correspondence marker on the electronic component side may be distinguished by uppercase / lowercase letters such as “A” and the correspondence marker on the second identification information side “a”.
Further, for example, the same character may be written in different fonts (fonts), such as Gothic and Mincho.

  The identification information 25 has been described as an example in which the part number of the electronic component 21 is used. However, the identification information 25 may be a constant (resistance value, capacitance value, characteristic value, etc.) of the electronic component 21, or may be a voltage / current limit value, a rated voltage, etc. Good. Alternatively, information indicating the operation function of the electronic component 21 may be used.

In order to improve the visibility of the substrate management number 50, the front surface of the substrate management number 50 is set as a non-visibility reduction portion of the substrate case 70. The non-visibility reduction portion can be considered variously besides the above example. That is, all the portions on the substrate case 70 where the visibility is lowered are the visibility-decreasing portions, and the portions not corresponding to them are the non-visibility-decreasing portions.
The part that reduces visibility means a hole part, thickness change part, bent part, rib, screw strut, concave part, convex part, or stamped part that corresponds to the above-mentioned stepped part and smaller than the board management number description area There are various types such as a portion where the thickness is irregular in the gate portion during injection molding.
Therefore, the non-visibility reduced portion is an area excluding these various visibility reduced portions. Further, it is an area excluding the above-described printing section and seal attachment sections such as the seal seal 77.
In addition, there is a portion of reduced visibility that does not correspond to the stepped portion. For example, parts that are opaque but not stepped, parts that are not opaque but have a very low light transmittance, and parts that cause irregular light refraction are also parts of reduced visibility. It can be considered that the lowered portion indicates other than these.
A non-visibility reduction portion in the cover body 80 may be considered in the same manner.

Furthermore, the non-visibility reduction part which becomes the front of the board | substrate management number 50 is good also as a part which improves a visibility actively. For example, the opening portion 78A, the cutout portion 78B, and the opening portion 83 are examples thereof, but the front portion of the substrate management number 50 in the substrate case 70 or the cover body 80 may be a thin portion even if it is not an opening.
Alternatively, the front portion of the substrate management number 50 in the substrate case 70 or the cover body 80 may be formed as a magnifying lens-shaped curved surface that enlarges and visually recognizes the substrate management number 50. Thereby, reading of the board | substrate management number 50 by an inspector can also be made easier.
