It is also conceivable to have
Usually, the board management number is described in a first description format using a character string including characters (including numbers and symbols) that are continuous in a horizontal line. In this case, when the description area cannot be sufficiently secured on the substrate, each character is written. Must be extremely small. Therefore, the board management number can be described in a sufficient character size by performing the description in the second description format.
In the present specification and claims, the term "letter" is used as a general term for letters, hiragana, katakana, numbers, symbols, and the like used for a board management number.

In the gaming machine described above, the second description format may be a description format in which constituent characters of the board management number are arranged in a plurality of columns.
This enables the board management number to be written in a sufficient character size even if a horizontally long area cannot be secured on the board.

Format.
This allows the board management number to be written in a sufficient character size even if an area for writing the entire board management number cannot be secured on the board.

In the gaming machine described above, the board management number includes manufacturer information of the gaming machine and other information, and the second description format includes a management number component as the manufacturer information and the other information. It is desirable that the management number component part as the information has a description format described in a different column or a separated position.
When described in a different column or a separate position as the second description format, the board management number can be easily read by separating the management number component as the manufacturer information and the management number component as other information. .

In the gaming machine described above, it is conceivable that some of the plurality of electronic circuit boards have a board management number described in the first format.
For example, a board management number is described in a first description format on a board that can secure a sufficient description area, and a board management number is described in a second description format on a board for which it is difficult to secure a description area in the first description form. Use the description format properly.

In the gaming machine described above, the board management number is assumed to include manufacturer information of the gaming machine and other information, and in the second description format, a management number component as the manufacturer information, It is conceivable that the management number component part as information is described by a different method.
For example, the management number component as the manufacturer information is a character common to each board. On the other hand, the management number constituting part as other information may be different for each board. Therefore, by describing the common character portion in a different manner, the efficiency of the description of the common character portion is realized.

These boards in the ball game machine 100 and the torso gaming machine 200 of the present embodiment are each assigned a board management number.
Further, for each individual electronic component on the substrate, visually recognizable identification information is shown to indicate the information. The identification information is, for example, a component number uniquely assigned to each electronic component. In particular, the identification information can be clearly recognized for individual electronic components regardless of the density or arrangement of the electronic components on the substrate.
In the ball game machine 100 and the spinning game machine 200 of the present embodiment, at least one or more substrates correspond to any of the following types with respect to identification information on 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, and There are requests to make it difficult.
However, when a plurality of electronic components are densely arranged on a substrate, it is difficult to accurately display identification information corresponding to each of the plurality of electronic components. In addition, due to an increase in the number of electronic components in the substrate region due to the circuit configuration, the substrate region is squeezed, making it difficult to display identification information on the substrate. In such a situation, since many electronic components and identification information are mixed, it is difficult to identify the electronic components at an early stage even if the electronic components are illegally replaced.
Therefore, in the present embodiment, the electronic components can be easily identified on the electronic circuit board by any 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. Here, FIGS. The types of information notation will be explained.

There is no problem when recognizing individual components.
However, depending on the arrangement of the electronic components on the substrate, the identification information 25 cannot be described near the electronic component 21 in many cases. Therefore, as described below, the notation as the above-described second identification information is also used.

In this example, the second description format is a description format in which the constituent characters of the board management number are arranged in a plurality of columns. That is, the constituent characters as the board management number 50B are divided into management number constituent parts 51 and 52, and these are described as two rows arranged vertically.

Note that other specific examples of the second description format are also conceivable. For example, as shown in FIG. 23 to be described later, the description format in which the constituent characters as the board management number 50B are divided into management number constituent parts 51 and 52 and these are described at separated positions on the electronic circuit board is also a second form.

Depending on the type of board, it may be described without including manufacturer information.
14 to 17, the board management number 50 is tentatively indicated as “FJ + AB1231C”. However, “FJ” is an example of manufacturer information set unique to a manufacturer, and “AB1231C” is other information (date information). And model-specific numbers).
In the case of FIGS. 16 and 17, the board management number 50B describes the manufacturer information and other information in two rows (two columns).

<5. Board Identification Information and Board Management Number of Embodiment>

The board 10 in the above-described embodiments such as the boards 10A and 10B is configured so that the identification information 25 can be clearly recognized for each individual electronic component 21 irrespective of the density or arrangement of the electronic components 21 on the board. ing. For this purpose, the first identification information such as the identification information 25 shown in FIGS. 9A, 9B, and 9C described above and the second identification information such as FIGS. 9D, 9E, 9F, 9G, and FIGS. And are used together.
And on such a board, the board management number 50 is clearly described in a certain character size. For this reason, the first description of the board management number 50 is given for each board or for each board face of the first main face 10x and the second main face 10y according to the plane size of each board and the convenience of the mounting area J. Format and the second description format.
Further, the substrate 10 according to the embodiment also realizes easiness of wiring, easiness of terminal identification of a BGA type IC, and the like.
Here, as the board configuration of the embodiment, details of the arrangement and notation of the electronic component 21 (electronic component group 22) and the identification information 25 (identification information group 27) shown in the above-described type, and the board management number 50 are described. Will be described.

First, the use of the first identification information and the second identification information together will be described with reference to FIGS. 18A and 18B.
FIG. 18B shows the identification information 25 as first identification information at a position that is a first distance K1 from the electronic component 21, that is, near the electronic component 21. The first distance K1 is a distance at which the correspondence is clear in the vicinity without using the lead line 33 or the like. If the identification information 25 as such first identification information is described for all the electronic components 21 on the substrate 10, the information about each electronic component 21 becomes clear.
However, in many cases, the identification information 25 must be written at a separated position via the second distance K2 longer than the first distance due to the arrangement position of the electronic components or the dense arrangement. In such a case, the identification information 25 is described as the second identification information as shown in FIG. 18A.
For example, 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, and the surrounding lines 31 and 32 of the two are connected by a lead line 33. With such a notation, the correspondence between the electronic component group 22 which is a group 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 described in a manner as exemplified in FIGS. 9D to 9G and FIGS.

The substrates 10A and 10B shown in FIGS. 14 to 17 have such first identification information and second identification information as exemplified by reference numerals P1 to P7. That is, as the identification information 25 that is visibly displayed to indicate information of the individual electronic components 21 mounted on the substrate 10, the identification information 25 is displayed near the electronic component as a position via the first distance K1 from the electronic component. First identification information and second identification information written from the electronic component via a second distance K2 longer than the first distance K1.
As described above, the identification information 25 is not necessarily the first identification information in the vicinity of the electronic component 21, and the identification information is easily understood for each electronic component by using the second identification information according to the component arrangement and its density. It can be expressed in the state.

Note that the first distance K1 does not indicate a specific value of the distance. The first distance K1 is a distance by which the written position of the identification information 25 can be recognized as being in 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 also does not indicate a distance having a specific value. 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 being in the vicinity of the electronic component 21, and is a distance recognized as being long as compared with the first distance K1. is there.
The “near” is a distance where the correspondence between the electronic component 21 and the identification information 25 is clear even without the lead line 33 and the corresponding marker 34. Therefore, when looking at a specific electronic circuit board, if the identification information 25 is provided in “near” 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 cannot be said to be “near” and is separated by a distance longer than the first distance K1, the distance between the identification information 25 and the corresponding electronic component 21 is increased. "The second distance K2" is obtained.
Note that the “second distance” is a distance between a certain electronic component 21 and the corresponding identification information 25. As shown as a distance K2 ′ in FIGS. 18A and 18C, the electronic component group 22 and the identification information group It may be considered as a distance between 27. That is, when the electronic component group 22 and the identification information group 27 are considered, the “second distance” is the illustrated distance K2 ′.

Further, the boards 10A and 10B are mounted on the boards 10 in such a manner that an interval between at least one adjacent electronic component 21 is such that a notation area of the identification information 25 of a predetermined character size cannot be secured. With respect to the electronic component group 22 including the plurality of electronic components 21, identification information 25 based on the second identification information is described corresponding to each electronic component 21 in the electronic component group 22 (see reference numerals P5, P6, and P7).
FIG. 19A shows this state. In the electronic component group 22 of FIG. 19A, the horizontal interval in 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 described has, for example, a size in the character string direction “w2” and a size in the height direction “h2”. In this case, w1 <w2 and h1 <h2.
In such a case, it is difficult to write the identification information 25 near each electronic component 21. Even if it can be described, the correspondence is difficult to understand, and the visibility is reduced. 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 w1 <w2 or h1 <h2 is satisfied, it is appropriate to write the identification information 25 as the second identification information.

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

Note that there may be a concept that the identification information 25 as the second identification information is described for all the electronic components 21 on the substrate 10. However, it is desirable to use the first identification information if the correspondence can be clearly described as the first identification information. For example, if the second identification information is dared to be used for all the electronic components 21 including the non-dense parts, the identification information 25 is concentrated on the edge of the base 10 and the number of the lead lines 33 increases, This is because the correspondence may be difficult to determine.
That is, the identification information 25 is described as the first identification information as much as possible on the substrate 10, but the identification information is written in a portion far from the electronic component by adopting the second identification information for the dense electronic components. It is also appropriate to reduce By using such first and second identification information together, identification information notation with good visibility and information recognizability can be realized.

Further, in the substrates 10A and 10B, an example in which the direction of the character string forming all the identification information 25 as the first identification information and the second identification information is the direction parallel to the long side of the corresponding electronic component 21. And
FIG. 19B shows the model. An electronic component 21H and an electronic component group 22H in which the horizontal direction is the long side direction in the drawing, and an electronic component 21V and an electronic component group 22V in which the vertical direction is the long side direction in the drawing. All of the identification information 25 corresponding to them has a character string direction parallel to the long side of the corresponding electronic component 21.
Regarding the identification information 25 (see symbols P1 to P7) on the substrates 10A and 10B in FIGS. 14 to 17, the rules in the character string direction as in FIG. 19B are reflected. That is, the identification information 25 has a character string direction parallel to the long side of the corresponding electronic component 21. Further, when there is an electronic component 21 arranged in a different long side direction in the electronic component group 22 as shown by a reference numeral P7 in FIG. 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 with the character string direction as described above.
By setting the long side direction of the electronic component 21 as the character string direction also for the second identification information, the identification information 25 corresponding to the electronic component 21 can be easily recognized. That is, for the second identification information at a distant position, the corresponding electronic component 21 can be easily identified by the regularity in the vertical and horizontal directions in the character string direction.

In any case, it is possible to improve the recognizability of the correspondence and the visibility of the identification information 25 by expressing all the identification information 25 according to the rule that the long side direction of the electronic component 21 and the character string direction match. Can be.
However, exceptions may be made in some cases. For example, it is conceivable that some of them are out of the rule in accordance with the arrangement of components on the board 10 and the margin for notation. In such a case, it is desirable to clarify the correspondence by using the lead wire 33 or writing it in the vicinity of the electronic component 21.
If the above-described rules in the character string direction are applied to some (for example, most) pieces of the identification information 25 on the substrate 10, not necessarily all the identification information 25, the discrimination and visibility of the correspondence will be improved. Can be improved.
For the electronic component 21 having a substantially square or substantially circular planar shape, any of the horizontal direction and the vertical direction described with reference to FIG. 19B may be considered as the long side direction.

In the substrates 10A and 10B, 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 corresponds to adjacent second identification information. It is 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, and P7).
Explaining with reference to FIG. 18A, adjacent identification information 25 in the identification information group 27 is shown separated by a third distance K3. This third distance K3 is shorter than the second distance K2 '.
Notation using the second identification information makes the identification information easy to understand for each part regardless of the arrangement of parts and the density of the parts, but a large number of identification information 25 are described in the second identification information group. Then, on the contrary, the display becomes difficult to see. On the other hand, if the unity 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. This makes it possible to maintain the unity of the identification information group 27, improve the recognizability of the correspondence with the electronic component group 22, and make each identification information 25 in the identification information group 27 easy to see.

18A, the plurality of pieces of identification information 25 in the identification information group 27 surrounded by the surrounding line 32 are represented by the third distance K3, so that the range of the identification information group 27 is further clarified by the surrounding line 32. In addition, the identification information 25 can be easily viewed, and the recognition of the correspondence with the electronic component 21 can be improved.
In the above, the third distance K3 does not indicate a distance having a specific value. The third distance K3 is a notation interval between adjacent identification information 25. In the present embodiment, the third distance K3 is a distance recognized as being short as compared with the second distance K2 ′ (or K2).
Further, in all the identification information groups 27 on the substrate 10, the distance between the identification information 25 does not necessarily have to 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.

In the boards 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 is shown as identification information (see symbols P5, P6, P7).
For example, in FIG. 18A, “C101”, “C102”,..., Which are identification information 25 as capacitors, are grouped in the identification information group 27 with respect to the group of electronic components 22 of the electronic component 21 as capacitors. Further, in FIG. 18C, “R10”, “R11”,..., Which are identification information 25 as resistances, are grouped in the identification information group 27 for the electronic component group 22 group of the electronic components 21 as resistances.

As described above, the electronic component group 22 and the identification information group 27 are applied to the same type of electronic component. As a result, the correspondence between the electronic component group 22 and the identification information group 27 becomes clearer, and it is possible to easily understand which electronic component 21 each identification information 25 is.
In particular, since each identification information 25 in the identification information group 27 enclosed by the encircling line 32 as shown in FIG. 18A is identification information of the same type of electronic component, it is easier to grasp a group of identification information groups. .

Further, by applying the same type of electronic component 21 in this manner, 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 notation efficiency. For example, when the identification information 25 of nine capacitors is put together, it is possible to write only one “C” indicating a capacitor as an initial of the identification information 25 at the head as shown in the figure.
That is, as shown in the upper left of FIG. 18D, other than one piece of identification information “C101”, it may be simply expressed as “102” “103”.
Also, 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 described as “101” “102” “103”. .
Also, as shown in the lower left of FIG. 18D, “C” may be added in the vicinity of the surrounding line 32 and the inside of the surrounding line 32 may be described as “101”, “102”, “103”,. .
Also, as shown in the lower right of FIG. 18D, after “C” is attached inside the enclosing line 32, they may be described as “101”, “102”, “103”,.
In this way, the notation is streamlined to reduce the total number of characters in the identification information group 27, thereby reducing the area size required for the identification information group 27 and, for example, for arranging the components on the board 10 and so on. It is possible to cope with cases where it is difficult to secure a large area.

Note that not all sets of the electronic component group 22 and the identification information group 27 need to be formed for the same type of electronic component. For example, a resistor and a capacitor are mixed in one electronic component group 22, and a 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 group of the electronic component group 22 and the group of the identification information group 27 for the same type of electronic component, it is possible to improve the correspondence relationship and the recognizability of the group.

In addition, the substrates 10A and 10B have an enclosing line 32 written for the second identification information 25. For example, as shown in FIG. 18A, a surrounding line 32 is described around the identification information group 27 (second identification information group) (see reference numerals P5, P6, and P7).
9F, 9G, 10C, and 10D to 10G, an enclosing line 32 may be provided around one piece of identification information 25 in some cases.
By providing an enclosing line for the second identification information in this manner, the recognizability of the second identification information can be improved. In particular, when the second identification information is described as the identification information group 27, by providing the surrounding line 32, the recognizability of a group of the identification information group 27 can be improved, and the range corresponding to the electronic component group 22 can be clarified.

Also, for the electronic component corresponding to the second identification information in which the enclosing line 32 is indicated, the enclosing line 31 on the component side is indicated.
For example, in the portions indicated by reference numerals P5, P6, and P7, the enclosing line 31 is also provided in the electronic component group 22. Also, as shown in FIGS. 9G and 10F, an enclosing line 31 may be provided for a single electronic component 21 corresponding to the second identification information.
In this manner, 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 line 31 and the identification information-side enclosure line 32, respectively. Thereby, the recognizability of each can be enhanced, and the correspondence can be clarified and the visibility can be improved.

9E, 10B, 10H, 11C, 12B, and 13E, no enclosing line is provided on the identification information 25 side, and an enclosing line 31 is provided on the electronic component 21 (electronic component group 22) side. In some cases, it is provided.
In any case, by providing the enclosing line 31 on the electronic component 21 (electronic component group 22) side, it is possible to enhance the recognizability of the electronic component 21 corresponding to the identification information 25 and to clarify the range of the electronic component group 22.

The electronic component group 22 can be set flexibly by the surrounding line 31 on the electronic component 21 side.
For example, among the three locations denoted by reference numeral P5 in FIG. 17, two electronic component groups 22 are set by the enclosing line 31 in two locations substantially at the center, where the electronic components 21 are densely packed. In FIG. 21, a substantially central portion where the electronic components 21 are densely packed is divided into four electronic component groups 22 by a surrounding line 31.
In this manner, the electronic component group 22 can be flexibly set by the enclosing line 31 without depending on the component arrangement. 22 can be set. This makes it possible to realize easy-to-see identification information notation according to the arrangement on the substrate 10, the substrate area, and the like.
In other words, the electronic components 21 densely arranged in a certain area need not necessarily be one electronic component group 22. The electronic component group 22 is divided according to the status of the notation area of the identification information group 27 on the substrate 10 and the identification information group 27 is provided for each of them.

In the boards 10A and 10B, 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 correspond to each other. Markers 34 and 35 are provided to indicate the corresponding relations (see symbols P6 and P7).
Thereby, the correspondence between the surrounding lines 31 and 32 is clearly shown. In particular, when the lead lines 33 cannot be connected between the enclosing lines 31 and 32, or when the lead lines 33 are possible but too long, or when the lead lines 33 become difficult to see due to a wiring pattern or the like, a corresponding marker is used. It is preferable to show the correspondence using 34 and 35.

  Note that the surrounding lines 31 and 32 are not necessarily shown by the corresponding markers 34 and 35, but are shown in FIGS. 10A to 10C, 10E, 10G, 10H, 12A to 12C, 13A, 13B, and 13D. 13E. That is, the corresponding markers 34 and 35 may be attached to both or one of the electronic component 21 (electronic component group 22) and the identification information 25 (identification information group 27) without providing the enclosing line 31. 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 corresponding relationship at a position separated by the corresponding markers 34 and 35 can be clarified.

On the boards 10A and 10B, a leader 33 is written to indicate the correspondence between the identification information 25 (identification information group 27) as the second identification information and the electronic component 21 (electronic component group 22). (See symbols P2 and P5).
The correspondence between the second identification information and the electronic component 21 can be clarified by the lead line 33. 9D to 9G and FIGS. 11A to 11E are examples of the manner in which the correspondence is indicated by the lead line 33.

In the substrates 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. , Or around the identification information group 27, a portion where an enclosing line 32 on the identification information side is written and a lead line 33 is written between the corresponding enclosing line 31 on the component side and the enclosing line 32 on the identification information side. (Symbol P5, see 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 is indicated by a lead line 33. By doing so, the recognizability of the correspondence between the electronic component 21 and the identification information 25 can be improved.
Note that it is not always necessary to provide the lead 33 between all the electronic components 21 (the electronic component group 22) and the identification information 25 (the identification information group 27). In the portion where the lead wire 33 is provided, the above-described effects can be obtained.

Further, on the substrates 10A and 10B, the plurality of identification information 25 in the identification information group 27 is described in 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, FIG. 21 illustrates four sets as the electronic component group 22 and the identification information group 27. In each of the identification information groups 27, the identification information 25 such as “C101” is described in the same arrangement relationship as the arrangement relationship of each electronic component 21 in the electronic component group 22 indicated by the leader line 33.
For example, as for the electronic component group 22 in which the electronic components 21 are arranged in 4 rows and 3 columns, the identification information group 27 also describes the identification information 25 in 4 rows and 3 columns. When the electronic components 21 are arranged such that the first row is three, the second row is four, and the third row is three, the corresponding identification information group 27 also has three first rows and four second rows. And the third line describes the identification information 25 in an arrangement of three.
Thereby, it is possible to make it extremely easy to identify which electronic component 21 in the corresponding electronic component group 22 each identification information 25 in the identification information group 27 corresponds to. By making the shapes of the identification information group 27 and the electronic component group 22 similar, the correspondence between the groups can be easily understood, and the relationship between each electronic component 21 and each identification information 25 can be easily understood by the positional relationship within the group. That's why.

Also, the electronic component group 22 and the identification information group 27 whose arrangement relations are matched in this way are clarified by the enclosing lines 31 and 32, and are further associated with the lead lines 33, so that each identification information 25 and the electronic component 21 Responsiveness and recognizability are significantly improved.
In a case where the electronic component group 22 and the identification information group 27 cannot be connected by the leader line 33, it is preferable that the correspondence is indicated by the correspondence 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 does not have to be the same as the arrangement of each electronic component 21 of the corresponding electronic component group 21. As long as the identification information group 27 has at least the same arrangement relationship of the electronic components 21 of the corresponding electronic component group 21 as the arrangement of the identification information 25, the above-described effect 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 electronic components 21 of the corresponding electronic component group 21, the effect of improving the recognizability of the entire board 10 is great.

In addition, the boards 10A and 10B have lead lines 33 written so as to associate the electronic component 21 with the identification information 25 arranged on the board end side when 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 in a direction toward the end of the substrate, that is, any of the edges 11, 12, 13, 14. The state in which the identification information 25 (identification information group 27) is pointed out is obtained by arranging the second identification information at a position other than the center of the substrate.
Thereby, the information of the electronic component 21 at the center of the board having a relatively high component density can be clearly described by the second identification information near the end. By not arranging the second identification information in the center of the substrate, the identification information 25 itself as the second identification information can be easily viewed.
Note that not all the lead lines 33 are necessarily drawn from the electronic components 21 (electronic component group 22) near the center of the board to the identification information 25 (identification information group 27) near the outer edge of the board. This is because the presence of such a lead line 33 (that is, the positional relationship between the electronic component 21 and the identification information 25) can be realized in a part, so that the efficiency of arrangement on the substrate and the visibility of the identification information 25 can be realized.

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 may be any one of the identification information based on the first edge and the identification information based on the second edge. It is formed as a bridge (see reference numerals P1 to P7 in FIGS. 14 and 15).
The identification information based on the first edge refers to the electronic component 21 whose long side is arranged in parallel with the first edge (end 12) of the substrate 10 and the character string direction is the first edge. And the first end side (end side 12) side is below the character.
The identification information based on the second edge refers to the electronic component 21 whose long side is arranged parallel to the second edge (end 13) of the substrate 10 and the character string direction is the second edge. And 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, a first main surface 10x of the substrate 10, and FIG. 20A shows a second main surface 10y. Here, the identification information 25 such as “C101” is illustrated, but any of the identification information 25 is either based on the edge 12 or based on the edge 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 on the lower side (the direction indicated by the arrow DR1 is upward). .
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 on the lower side (the direction indicated by the arrow DR2 is upward).
That each of the identification information 25 for each electronic component 21 is either the first edge reference or the second edge reference means that the notation of all the identification information 25 is two sides (the edge 12 and the edge 12). The state is easy to read when viewed from the end side 13).
Further, since the character string direction 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.
Thereby, the correspondence between the identification information 25 is clarified, and the identification information 25 is easily read.

In addition, such a substrate 10 has a direction in which one of the first end side (end side 12) and the second end side (end side 13) is the lower end, and is used for the ball-ball game machine 100 and the torso game machine 200. It is appropriate to be attached.
In FIG. 20C, the outline of the housing of the ball game machine 100 or the torso gaming machine 200 is indicated by a broken line, and the substrates 10-1 and 10-2 are directed in the directions indicated by arrows DR1 in FIGS. 20A and 20B. Is installed so that it faces upward.
By doing so, the identification information 25 based on the first side (end 12) is in a state where a viewer can normally recognize it when attached to the gaming machine, and the characters are displayed upside down. Not very easy to see.
In the identification information 25 based on the second end (end 13), the character is horizontal when viewed from the viewer, but since the directions are aligned, it is not so difficult to read.

The identification information 25 is unified as either the first edge reference or the second edge reference on both the front and back substrate surfaces of the first principal surface 10x and the second principal surface 10y.
By unifying the vertical direction on the front surface and the back surface of the board 10, the notation of the identification information is easy to see 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.
In addition, for example, in a case where the game device is attached vertically to the gaming machine such that the end side 14 is inserted, both the first main surface 10x and the second main surface 10y are connected to the second end side (end side 13). ) The reference identification information 25 becomes easy to see.

As described above, the board 10 is attached to the gaming machine such that 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 such that either the first end (end 12) or the second end (end 13) faces downward. As a result, there is no identification information 25 that must be visually recognized in an upside down state on the substrate 10 attached to the ball-and-ball game machine 100 or the torso gaming machine 200, so that the electronic component 21 can be easily identified. Can be.
It is best that all the identification information 25 be based on either the first edge reference or the second edge reference. However, the character string direction or the character There may be identification information 25 in which the vertical direction of the character is exceptional. If the identification information 25 based on 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. Electronic component 21. In FIG. 16, the identification information 25 is the electronic component 21 indicated as “IC13” to “IC17”.
By arranging some of the electronic components 21 in an oblique state as described above, it is possible to easily route the wiring pattern on the substrate 10 and improve the manufacturing efficiency.

This will be described with reference to FIG. FIG. 23 shows an electronic component 21H in a diagonal state together with an electronic component 21H having a long side parallel to the end 12 and an electronic component 21V having a long side parallel to the end 13.
The electronic component (IC) 21S whose identification information 25 is “IC100” and the electronic components 21H and 21V whose identification information 25 is “CN10” and “CN20” are focused on.
The “IC 100” has a number of terminals, and is connected to the connectors “CN10” and “CN20” and a number of wires. The electronic component 21 as a connector is usually arranged near the edge on the substrate 10 and parallel to the edge.
Here, when viewed from the connector “CN10”, two sides of “IC100” appear in front. Therefore, it is easy to design the wiring 80 for the terminals on the two sides.
Also, when viewed from the lower right side of the drawing of “IC100”, the connectors “CN10” and “CN20” are seen obliquely from the front. This makes it easy to design the wirings 80 and 81 for the connectors “CN10” and “CN20”.

  That is, when the other electronic components 21H and 21V are mounted in such a manner that the planar shape is substantially square and each side of the substantially square is parallel to each end (11 to 14) of the substrate 10. By providing the electronic components 21S mounted in an oblique state, it is possible to facilitate the routing of the wiring pattern between the electronic components on the substrate 10. This is because the electronic components 21H and 21V and the electronic component 21S can create a positional relationship that makes it easy to see the other side of each other.

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 the oblique state. In the case of a substantially square planar shape, any may be the long side direction.
Therefore, as the identification information 25, a character string parallel to the side edge 12, a character string parallel to the side edge 13, and a character string in an oblique direction exist. By doing so, the correspondence between the identification information 25 as the second identification information and the electronic component 21 becomes clearer. That is, it is clear at a glance that the oblique character string corresponds to the electronic component 21S in the oblique state.
Also on the electronic component side, the electronic components 21H parallel to the edge 12, the electronic components 21V parallel to the edge 13, and the electronic components 21S mounted diagonally are mixed, so that the individual electronic components 21 can be visually distinguished. Is improved.
In the case of the electronic component 21S, the direction of the character as the identification information 25 is inclined, for example, as compared with the character of the identification information 25 based on the first side (end 12). As described with reference to 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 such that the first end (end 12) faces downward. In the case of the electronic component 21S as shown in FIG. 23, the direction of the character as the identification information 25 is not upside down when it is attached to the gaming machine body. That is, the lower side of the character has the end sides 12 and 14 obliquely lower, respectively, and the character is attached to the gaming machine such that one end face is lower.
By doing so, even in the case of the electronic component 21S, in the state where the electronic component 21S is attached to the gaming machine, the vertical direction of the character forming the identification information is not opposite to the vertical direction of the gaming machine body. And visibility can be improved.

Further, among the mounted electronic components 21 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 a chip bottom surface. The bottom terminal type electronic component is, for example, a BGA type IC or a PGA (pin grid array) type IC. Then, first terminal information indicating a terminal position in the column direction of the electronic component 21 and second terminal information indicating a terminal position in the row direction are marked on the substrate 10 so as to be visible.
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 shown, a large number of terminals 51 are formed in a matrix on the bottom side. In addition, as shown in FIG. 22D, the terminal 51 is not formed on the entire bottom surface, and there is also a type in which the terminal is not formed on a part of the bottom surface.
It is difficult to visually discriminate terminals such as the BGA type IC 50 whose terminals do not appear on the substrate 10.

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 row 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 all terminal column numbers and terminal row numbers need not be described. For example, as shown in FIG. 22F, the first and last terminal row numbers “A” and “AH” may be described, and the first and last terminal row numbers “1” and “28” may be displayed. Of course, other than this, intermittent terminal column numbers and terminal row numbers may be used.

In the board 10B of FIG. 16, an example is shown in which the first terminal information 55 and the second terminal information 56 are described as shown in FIG. 22E in the electronic component 21 of “IC17”.
Further, in the board 10A of FIG. 14, an example is shown in which the first terminal information 55 and the second terminal information 56 are described in the electronic component 21 of “IC5” as shown in FIG. 22F.
By describing the first terminal information 55 and the second terminal information 56 for the bottom terminal type electronic component in which the plurality of terminals 51 are arranged on the chip bottom surface in this manner, 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. Notation is used.
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 terminal information of the column / row can be obtained. Can be easily recognized.
Note that, in the bottom terminal type electronic component, which one is the column direction or the row direction is arbitrary. A certain direction may be considered as a column direction, and a direction perpendicular to the column direction may be considered as a row direction.

Also, as shown in FIGS. 22E and 22F, and further 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. .
By unifying the vertical direction of the characters in the first terminal information 55 and the second terminal information 56 in this way, it is possible to make the notation of each information easy to see and to easily grasp the terminal position.
This up-down direction may be 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, the direction is the same as the character direction of the identification information 25 in the oblique arrangement. By doing so, the legibility of the first terminal information 55 and the second terminal information 56 can be improved.

Further, the first terminal information 55 is represented by a first type of character, for example, alphabet, and the second terminal information 56 is represented by a second type of character, for example, numeral.
By writing in different character types in this way, the first terminal information 55 and the second terminal information 56 can be easily distinguished, 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 are such that the vertical direction of the character is the same as the identification information 25 based on the first edge (end 12). And
In the electronic component 21 of “IC17” in FIG. 16, the first terminal information 55 and the second terminal information 56 have the same vertical direction of the character 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 (end 12) or the second end (end 13) faces downward. Then, similarly to the identification information 25, the first terminal information 55 and the second terminal information 56 are also turned upside down on the board 10 attached to the ball game machine 100 or the torso game machine 200. Never. Thereby, the visibility of the first terminal information 55 and the second terminal information 56 can be improved even in a state where the terminal information is attached to the gaming machine.

As described above, the terminal arrangement of the electronic component 21 (bottom terminal type electronic component) in which the plurality of terminals 51 are arranged on the chip bottom surface can be easily confirmed, which is convenient for manufacturing and inspection.
Note that electronic components 21 such as capacitors are likely to be densely arranged on the back surface of the BGA type IC. For example, in the case of the substrate 10B shown in FIGS. 16 and 17, on the second main surface 10y side, a large number of electronic components 21 such as capacitors are arranged in a portion corresponding to the back of the "IC 17". Even 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 be described in the form of the second identification information as described above.

Subsequently, the board management number 50 will be described.
As described above, the board management number 50A in the first format is described on the board 10A in FIGS. On the other hand, the board management number 50B of the second description format is described on the board 10B of FIGS.
The board management number is usually described in the first description format in which the constituent characters are composed of a single horizontal character string. In this case, if the description area cannot be sufficiently secured on the board, each character must be extremely small. No.
For example, in the examples of FIG. 14 and FIG. 15, since a description area having a height that can correspond to a relatively wide and large character size can be secured outside the mounting area J, the board management number 50A in the first description format can be described. ing. However, in the examples of FIGS. 16 and 17, such a horizontally long writing area cannot be secured outside the mounting area J.

  Therefore, in the case of FIG. 16 and FIG. 17, the constituent characters are divided into the management number constituent parts 51 and 52, and the board management number 50B written in two columns in which the characters are divided into two columns is described. In this way, even if a horizontally long area cannot be secured, the board management number 50B can be described with a sufficient character size. FIG. 21 also shows an example in which the board management number 50B in the second description format is similarly described.

In recent years, an extremely large number of electronic components are often densely arranged on the substrate 10. Wiring patterns are becoming more complicated. On the other hand, the plane size of the substrate itself cannot be increased unnecessarily for convenience in mounting on the ball game machine 100 or the spinning game machine 200.
Under these circumstances, the area occupied by the mounting area J on the board is large, and it is difficult to secure an area for describing the board management number 50. If the writing area is not sufficient, the writing is performed in such a manner that the character size is reduced and stuffed. However, in such a case, the visibility of the board management number 50 is significantly deteriorated.
In view of the above, the substrate management number 50 having a sufficiently large size can be described by using the second description format according to the description area circumstances of the substrate 10 without necessarily using the first description format.

Further, as another example of the second description format, as in the example of FIG. 23, the constituent characters of the board management number are divided into a plurality of management number constituent parts 51 and 52, and each management number constituent part 51, 52 Alternatively, it may be described at a distance from the top 10.
In the case of FIG. 23, there is a case where it is not possible to secure a horizontally long area enough to describe all the characters as the board management number 50 or an area that can be described in two columns outside the mounting area J. Even in such a case, the board management number 50 can be written in a sufficiently large character size by separating the two management number components 51 and 52 of “FJ” and “AB1231C” as shown in the figure.

In other words, if each column is written in the same position (nearby) in two columns as shown in FIGS. 16 and 17, the recognizability of all characters of the board management number 50 can be improved.
On the other hand, the separation description as shown in FIG. 23 is preferable in that a board management number with good visibility is realized when an area that can be described in two rows cannot be secured.

Here, the above-described notation of the identification information 25 also affects the expansion of the mounting area J, that is, the reduction of the area where the board management number 50 can be written.
For example, since 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 on the peripheral portion of the substrate 10 also increases.
Further, when the identification information group 27 is provided, a relatively large area is occupied, and this leads to an expansion of the mounting area J. In particular, since the identification information group 27 is often provided near the end 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 wire 33 is not divided by the board management number 50.
As shown in FIG. 21, a lead 33 is provided from the electronic component 21 (electronic component group 22) on the substrate 10 in a direction toward the end of the substrate, that is, any one of the edges 11, 12, 13, and 14. Pointing the identification information 25 (identification information group 27) by using the identification information 25 (identification information group 27) also promotes the occupation of the vicinity of the substrate edge by the identification information 25 (identification information group 27).
In addition, by using the corresponding markers 34 and 35, the identification information 25 and the identification information group 27 are more easily written on the periphery of the substrate 10.
If there is an electronic component 21S mounted in an oblique direction, the peripheral wiring, the identification information 25, and the identification information group 27 can easily approach the end of the board (for example, see FIG. 16).

Due to these circumstances, the area where the board management number 50 cannot be described 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 description number 50B in the second description format. In other words, when the identification information 25 (identification information group 27) as the above-described 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 as compared with 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 improved.

Specifically, the following substrates (a), (b) and (c) are desirable.
(A) As in the embodiment, a board having a board management number 50 </ b> B in a second description format and identification information 25 as second identification information separated from the electronic component 21.
When the second identification information, which is written away from the electronic component 21, is written in correspondence with the electronic component 21 by the leader line 33, the corresponding markers 34, 35, etc., the board is occupied widely, and the board management number in a horizontal row Often cannot be described. By using the board management number 50B in the second description format, the board management number can be described in 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 in a sufficient character size as compared with the identification information 25 using the board management number 50B in the second description format. The visibility of both the board management number 50 and the identification information 25 can be improved.

(B) A board having a board management number 50B in a second description format and an identification information group 27 as second identification information as in the embodiment.
The identification information group 27 is often described near the periphery of the substrate. That is, the elements are often concentrated in the central part. Then, there is a tendency that there is no room to write the board management number 50 near the periphery of the board. 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) A board having a board management number 50B in the second description format and second identification information indicated by a lead 33 drawn from the electronic component 21 toward the board end as in the embodiment.
The association of the second identification information in the board edge direction with the electronic component 21 by the lead line 33 facilitates the identification information 25 to be written on the periphery of the board. For this reason, there is a tendency that there is no room to write the board management number 50 near the periphery of the board. In this case, the board management number 50B having a large character size can be written in the second description format. This makes it easy to see the identification information 25 and the board management number 50 at the same time.

The board management number 50B in the second description format shown in each example of FIGS. 16, 17, 21, and 23 is composed of a management number configuration part 51 as manufacturer information and a management number configuration part 52 as other information. Is described in a different row or at a separate position.
When the two-column notation or the separated notation is used, by dividing the information by the manufacturer information portion and other information portions (date, model-specific code, etc.), the recognition of the board management number 50B by the viewer is not hindered. That is, the second description format can also be a description that allows the manufacturer information, date, model-specific code, and the like to be easily recognized.

Also, the management number component 51 as the manufacturer information and the management number component 52 as the other information may be described by different methods.
The management number component 51 as the manufacturer information is a character common to each substrate 10. On the other hand, the management number component 52 as other information may be different for each board. Therefore, by describing the common character portion in a different manner, the efficiency of the description of the common character portion is realized.
Examples of a method for describing the board management number 50 include a printing method, a photographic method, and a direct drawing method (for example, laser drawing).
For example, it is conceivable that the part of the manufacturer information “FJ” or “FJ +” uses the printing method, and the part of the other information “AB1231C” uses the direct drawing method.
It is also conceivable that a master film is used for a manufacturer information portion common to each model, and a method that does not require a master film is used for a portion of information different for each model.

Although a large number of substrates 10 are mounted on the ball-and-ball game machine 100 and the spinning-wheel gaming machine 200, it is not necessary that all the substrates 10 have the board management number 50B of the second description type. 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 area where each board 10 can be written.
Thus, it is possible to realize a board management number description that is easy to read according to the area situation of each board 10.
It is also conceivable that a board having a large board area uses the board management number 50A in the first description format, and a board having a small board area uses the board management number 50B in the second description format.

Further, in one substrate 10, the first and second description formats may be selectively used for the first main surface 10x and the second main surface 10y.
For example, FIGS. 14 and 15 show an example in which the first principal surface 10x and the second principal surface 10y have the board description number 50A in the first description format, but one of the front and back sides has the board description number in the first description format. The board 10 in which 50A is described and the board management number 50B in the second description format is described is also assumed. In particular, the description of the identification information 25 (identification information group 27) is different between the first main surface 10x and the second main surface 10y, so that the situation where the board management number 50 can be written is likely to be different. Therefore, by using the board management numbers 50A and 50B properly on the front and back, clear board management numbers can be written in both cases.

In each illustrated example, the board management number 50 is described on the board 10 in a state where the first edge (edge 12) is downward.
Such a substrate 10 is attached to the ball game machine 100 or the torso game machine 200 in a direction in which the first edge (end edge 12) is the lower end.
For example, in FIG. 20C, it is assumed that the substrates 10-1 and 10-2 are attached in such a manner that the edge 12 is downward. The board 10-1 shows an example in which a board management number 50B in two columns is shown, and the board 10-2 shows an example in which a board management number 50B in which the management number components 51 and 52 are separated is shown. For the viewer, the board management number 50 can be confirmed in the normal character direction. Therefore, the board management number 50 is very easy to read.

As described above, regarding the identification information 25, the visibility of the character is improved by setting the vertical direction of the character as the first edge reference or the second edge reference. Although the correspondence with each electronic component 21 is taken into consideration, it is not necessary to consider the correspondence with the individual electronic components 21 for the board management number 50B. It is required that the visibility is good in the state where the substrate 10 is attached to the ball game machine 100 or the spinning game machine 200. Therefore, if the substrate 10 is mounted in a direction in which the first end (end 12) is the lower end, the character as the board management number 50 may be described based on the first end. .
Therefore, when the board 10 is attached to the gaming machine in a 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 is determined according to the electronic component 21. It is appropriate to be described on the basis of the first edge or the second edge.
Thereby, the visibility of each identification information 25, the visibility of the board management number 50, and the identification information 25 and the electronic In addition, the correspondence of the parts 21 can be easily understood.

The character string direction of the identification information 25 is made 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 23, when there is an electronic component 21S mounted in an oblique direction that is non-parallel to each edge (11 to 14) of the board, the identification information 25 corresponding thereto is also included. The correspondence between the electronic component 21S and the identification information 25 is defined as a direction parallel to the long side direction of the electronic component 21S (that is, non-parallel to each end side (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 correspondence between the identification information 25 and 25S and the electronic component 21 is clarified, and the board management number 50 has a sufficient character size compared to the identification information using the first or second description format. Since the management number can be described, visibility of both the board management number and the identification information can be improved.

<6. Summary and Modified Examples>

According to the present embodiment, the board management number 50 can be clearly described in a sufficient character size on the electronic circuit board 10 of the ball-and-ball game machine 100 and the torso game machine 200, and can be easily viewed by a viewer. it can.

In addition, the wiring pattern of the electronic component 21 on the electronic circuit board 10 can be easily routed, and the manufacturing efficiency can be improved. This is due to the provision of the electronic component 21S mounted in an oblique direction.

In addition, the board management number 50B has been described as an example in which the board management number 50B is divided into two management number constituent parts 51 and 52 and described at a position apart from each other. However, the board management number 50B may be divided and described in three or more management number constituent parts.

Although the identification information 25 is made by silk printing, the display color of the identification information 25 can be variously considered. Silk printing colors are diverse.
It is also conceivable that the adjacent identification information 25 (identification information group 27) can be easily distinguished by, for example, changing the color of silk printing.
Further, the character size may be different for each identification information 25 (identification information group 27).
Regarding the board management number 50, it is desirable that the character size is clearly different from that of the identification information 25 so as to be clearly distinguished from the identification information 25.

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 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 may be represented by "a".
Further, the same character may be represented in different fonts (fonts), such as Gothic font and Mincho font.
