<5. Substrate Configuration 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. Together with.
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 the identification information 25 (identification information group 27) shown in the above-described type will be described.

First, referring to FIG. 18A and FIG. 18B, the use of the first identification information and the second identification information together is described.
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”... 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 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, and the third distance K3 is in the range that is recognized as short as compared with the second distance K2 '(or may be K2 is).
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 the 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 each 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, resistors and capacitors 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 resistance. May be mixed.
By providing at least a set 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 set 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 recognition of a group 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. 10H, FIG. 12A-12C, 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.

In addition, the electronic component group 22 and the identification information group 27 whose arrangement relation is 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. Correspondence and recognition 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 leader line is provided from the electronic component 21 (electronic component group 22) on the substrate 10 toward the substrate end, that is, the direction toward one of the end sides 11, 12, 13, and 14. The state in which the identification information 25 (identification information group 27) is pointed out 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. 20B shows, for example, the first main surface 10x of the substrate 10, and FIG. 20A 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 alternate long and short dash lines, but the substrates 10-1 and 10-2 are indicated by an arrow DR1 attached in FIGS. 20A and 20B. It is attached so that the direction is upward.
By doing so, the identification information 25 based on the first end side (end side 12) is in a state that can be normally viewed by the viewer when attached to the gaming machine, and the character is upside down. It is very easy to see.
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.

The board 10B shown in FIGS. 16 and 17 is mounted in an oblique state in which the planar shape is substantially square and each side of the substantially square is non-parallel to each edge (11 to 14) of the board. 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. FIG. 23 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. Therefore, it is easy to design the wiring 80 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. This facilitates the design of the wirings 80 and 81 for the connectors “CN10” and “CN20”.

  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, terminal column numbers “A” to “AH” of each column are shown as the first terminal information 55, and 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. Summary and Modification>

As described above, according to the present embodiment, the identification information 25 of the electronic component 21 is clearly and accurately displayed on the electronic circuit board 10 of the ball game machine 100 and the revolving game machine 200, and the electronic component 21 is displayed. It can be easily identified.
In addition, by clearly and accurately displaying 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.
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.
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).

  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 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”.
