In addition, when the electronic circuit board 2 in the board case 3 breaks down, it may be necessary to replace the board unit 4, but a tool such as a driver is not required for such replacement work. Therefore, the work efficiency can be improved.
By not requiring a tool at the time of work, it is possible to prevent the gaming machine 1 from being damaged or broken due to an erroneous operation of the tool.

11 to 13 show an example in which the board unit 4 is attached to the gaming machine 1 by latching, but the electronic circuit board 2 that is not housed in the board case 3 is played by latching. Even if it is attached to the machine 1, the same effect can be obtained.
Various other specific structures of the latching can be considered. For example, another regulated plate 8 may be provided instead of the shaft portion 7 and may be fixed by another slider unit 13 provided on the mounting surface 11 instead of the bearing portion 12. In addition, a rotation unit may be provided instead of the slider unit 13, and the movement of the regulated plate 8 may be regulated by rotating the flange portion 16b with the rotation unit.

[3-3. Hook stop]
An example in which the electronic circuit board 2 is attached to the gaming machine 1 by hooking is shown in FIGS. 14A and 14B.
The gaming machine 1 is provided with a mounting recess 9 for mounting the electronic circuit board 2. A plurality of hooks 17 are provided on the outer periphery of the mounting recess 9.
As shown in FIG. 14B, the hook 17 has a column portion 17a and an engagement portion 17b that protrudes laterally from one end of the column portion 17a. The engaging portion 17b is provided with a tapered surface 17c for facilitating the mounting of the electronic circuit board 2.

  When the electronic circuit board 2 is attached to the attachment recess 9 of the gaming machine 1, the column part 17 a of the hook 17 is elastically deformed, so that the engaging part 17 b is moved to the outside of the attachment recess 9, and the electronic circuit board 2 is attached to the gaming machine 1. That is, the electronic circuit board 2 is attached by being pushed into the attachment recess 9. That is, the electronic circuit board 2 can be easily attached. When the soldering surface 2b of the electronic circuit board 2 is substantially parallel to the mounting surface 9 and the mounting is completed, the column portion 17a is elastically restored, so that the engagement portion 17b and the component surface of the electronic circuit board 2 are restored. 2a engages.

  In a state where the engaging portion 17b and the component surface 2a of the electronic circuit board 2 are engaged, the electronic circuit board 2 is fixed to the mounting recess 9 as shown in FIG. 14B, and is prevented from falling off from the gaming machine 1. .

As illustrated, in the electronic circuit board 2, movement of the bottom surface of the mounting recess 9 in the in-plane direction is restricted by the wall portion of the mounting recess 9.
In the electronic circuit board 2, the vertical movement of the bottom surface of the mounting recess 9 is restricted by the bottom surface of the mounting recess 9 and the engaging portion 17 b of the hook 17.
In this way, the electronic circuit board 2 is attached and fixed to the attachment recess 9 of the gaming machine 1.

  In addition, the attachment location of the electronic circuit board 2 may not be a recess like the attachment recess 9. In that case, the movement of the bottom surface of the mounting recess 9 in the in-plane direction may be restricted by surrounding the electronic circuit board 2 with another member.

As described with reference to FIGS. 14A and 14B, the fixing of the electronic circuit board 2 by hooking using the hook 17 can be performed without using a tool such as a driver. In addition, a tool such as a driver is not required for unlocking.
This can improve the efficiency of the mounting work and contribute to cost reduction.
In addition, when the electronic circuit board 2 breaks down, it may be necessary to replace the electronic circuit board 2. However, since such a replacement work does not require tools such as a driver, work efficiency is improved. Can be improved.
By not requiring a tool at the time of work, it is possible to prevent the gaming machine 1 and the electronic circuit board 2 from being damaged or broken due to an erroneous operation of the tool.

14A and 14B show an example in which the electronic circuit board 2 is attached to the gaming machine 1 by hooking, but the electronic circuit board 2 housed in the board case 3, that is, the board unit 4, is hooked. Even if attached to the gaming machine 1, the same effect can be obtained.

[3-4. Insertion stop]
An example in which the electronic circuit board 2 is attached to the gaming machine 1 by insertion is shown in FIGS. 15A and 15B.
The gaming machine 1 is provided with an arrangement portion 18 for arranging the electronic circuit board 2. The aforementioned mounting recess 9 or the like can also function as the arrangement portion 18.
The placement unit 18 may be provided in a part of the gaming machine 1 or may be provided in a component attached to the gaming machine 1.
FIG. 15A shows a state in which the electronic circuit board 2 is arranged in the arrangement portion 18 provided in the component a attached to the gaming machine 1. Since the electronic circuit board 2 in this state is not fixed to the component a, the electronic circuit board 2 is easily dropped from the placement portion 18.

FIG. 15B shows a state where the component b is attached to the component a by the screw 300 or the like.
In the state shown in FIG. 15B, the component b is fixed to the component a, and the electronic circuit board 2 is fixed to the components a and b by being inserted into the component a and the component b.

  According to the insertion prevention, the electronic circuit board 2 inserted between them can be attached and fixed simultaneously by a member (for example, screw) for attaching the component b to the component a. This means that the screw 300 for attaching the component b to the component a is also used for fixing the electronic circuit board 2. That is, a dedicated member for attaching the electronic circuit board 2 to the component a (or component b) becomes unnecessary. Therefore, it is possible to reduce the number of parts, and it is possible to reduce costs and assembly man-hours.

In addition, when it becomes necessary to replace the electronic circuit board 2 due to a failure of the electronic circuit board 2, etc., it is only necessary to release the fixing of the component b to the component a, that is, to remove the component b from the component a. The electronic circuit board 2 is released from being fixed to the component a (or component b) and can be removed. Therefore, man-hours can be reduced even when the electronic circuit board 2 is removed.
Depending on the shape of the electronic circuit board 2 and the arrangement portion 18, it is possible to remove the electronic circuit board 2 from the gaming machine 1 simply by loosening the screw 300 without completely removing it.
Thereby, the improvement of the work efficiency in the case of replacing | exchanging the electronic circuit board 2 can be anticipated.

15A and 15B show an example in which the electronic circuit board 2 is attached to the gaming machine 1 by insertion, but the electronic circuit board 2, that is, the board unit 4 stored in the board case 3, is inserted. The same effect can be obtained even if it is attached to the gaming machine 1 by the retaining.

<4. Embodiment>

A plurality of types of electronic circuit boards 2 and board units 4 (boards K) are attached to one gaming machine 1. At this time, it is desirable to appropriately select from the various attachment methods (fixing methods) described above according to the conditions of the respective substrates K.

It is desirable that the substrate K attached to the gaming machine 1 can be attached and removed without using a tool for reasons such as reduction of work man-hours. In the above-described example, the screw stopper is an example that cannot be attached / detached without using a tool, and the latch stopper and the hook stopper are examples that can be attached / detached without using a tool.
That is, it is possible to reduce the number of assembling steps if a lot of latching and hooking can be used without using screws as much as possible.

However, depending on conditions such as the type of the substrate K and the mounting location, it is not always desirable to employ latching or hooking that can be attached and removed without using a tool.

[4-1. First Embodiment]
In the present embodiment, the attachment method is selected in consideration of the influence on the substrate K due to vibration during transportation or operation of the gaming machine 1.
The gaming machine 1 may vibrate during transportation or operation (a state in which a player is playing). For example, when transporting, vibration occurs due to the shaking of the vehicle when moving while being loaded on the vehicle at the time of shipment, and vibration occurs when the player presses a button during operation.

When the gaming machine 1 vibrates, the board K that is not sufficiently fixed may be rubbed with other members and the contact portion may be worn out or loosened. Wear or looseness of the attachment location may lead to dropping of the substrate K from the gaming machine 1 or damage to the substrate K.
Moreover, there is a possibility that the substrate K and parts may be blown by wear.
In addition, the player may feel uncomfortable due to the generation of vibration sound.

Specifically, in this embodiment, an attachment method is selected according to the height of the attachment position of the substrate K.
The board K attached above a predetermined position in the gaming machine 1 is fixed to the gaming machine 1 by screwing. And the board | substrate K attached below the predetermined position in the gaming machine 1 is fixed to the gaming machine 1 by latching or hooking.
In the following description of each embodiment, unless otherwise specified, the operating state of the gaming machine 1, that is, the state in which the glass door 105 of the bullet ball gaming machine 100 faces the front or the display of the spinning gaming machine 200. In the state where the window 208 faces the front, the vertical direction is described. Similarly to the operating state, the state in which the glass door 105 of the ball game machine 100 or the display window 208 of the revolving game machine 200 faces the front is described as “the standing state”, and the glass of the ball game machine 100 is displayed. A state in which the display window 208 of the door 105 or the swing game machine 200 faces upward is referred to as a “laying state”.

In this embodiment, the attachment method is selected according to the height of the attachment position of the substrate K. At this time, the attachment method may be selected for all the substrates K attached to the gaming machine 1. The attachment method may be selected only for some of the substrates K. An example of selecting the target substrate K is given below.
(A-1) All substrates K attached to the gaming machine 1
(A-2) Main control board K1 and effect control board K2
(A-3) Substrate K having a certain weight or more
(A-4) Substrate K in which the area of the component surface 2a is a certain level or more

  In the selection example (A-1), since the attachment method is selected for all the substrates K attached to the gaming machine 1, it is possible to reduce the number of substrates K that are insufficiently fixed, and an appropriate attachment method. Can increase the possibility of being selected.

In the selection example (A-2), the attachment method is selected only for the main control board K1 and the effect control board K2 among the various boards K attached to the gaming machine 1.
For example, with respect to the main control board K1 and the production control board K2 that play the main role in each board K, it is determined which method is used for fixing, and the other boards K are uniformly determined without making a determination. It may be fixed by latching or hooking. Thereby, it is possible to reduce the work man-hour for the attachment about the other board | substrate K. FIG.

In the selection example (A-3), it is determined which attachment method is applied to the substrate K having a certain weight or more based on the condition. Conversely, for the substrate K that is less than a certain weight, uniform latching or hooking may be employed without making a determination. Alternatively, a uniform screw stop may be employed.
The constant weight in the selection example (A-3) may be, for example, the average weight of all the boards K attached to the gaming machine 1 or the median value of the maximum weight and the minimum weight. Further, it may be the median value of the weights of all the boards K, may be calculated by taking into account the height of the center of gravity of the gaming machine 1, or may be calculated from the weight of the gaming machine 1.

As an example, an example in which a constant weight is determined in consideration of the height of the center of gravity of the gaming machine 1 will be described.
The gaming machine 1 has a different way of swinging upward depending on the height of the gravity center position of the gaming machine 1. Specifically, the higher the center of gravity of the gaming machine 1 is, the greater the swing of the gaming machine 1 is, and the lower the center of gravity of the gaming machine 1 is, the smaller the swing of the gaming machine 1 is. Therefore, when the constant weight of (A-3) is determined according to the gravity center position of the gaming machine 1, the constant weight in the gaming machine 1 with a high gravity center position is constant in the gaming machine 1 with a low gravity center position. It is desirable to make the value smaller than the weight of. Thereby, in the gaming machine 1 having a high center of gravity, the number of substrates K to be selected as an attachment method increases. That is, it is possible to increase the number of substrates K on which an appropriate attachment method is selected. Therefore, it is possible to reduce work man-hours by appropriately providing latching or the like while effectively suppressing the wear and damage of the substrate K.

As another example, an example in which a certain weight is determined in consideration of the weight of the gaming machine 1 will be described.
As the weight of the gaming machine 1 increases, the upward swing decreases, and as the weight decreases, the upward swing increases and the number of swings increases. Therefore, when the constant weight of (A-3) is determined according to the weight of the gaming machine 1, the constant weight in the light weight gaming machine 1 is greater than the constant weight in the heavy weight gaming machine 1. It is desirable to set a small value. Thereby, in the light weight gaming machine 1, the board | substrate K used as the selection object of an attachment method increases, and it can raise possibility that an appropriate attachment method will be selected.

In the selection example (A-4), for the substrate K having a certain area or more, it is determined which mounting method is applied based on the condition. And about the board | substrate K less than a fixed area, you may select the same attachment method uniformly, without performing determination based on conditions.
The fixed area in the selection example (A-4) may be, for example, an average area of the component surface 2a of the board K attached to the gaming machine 1, or a median value of the maximum area and the minimum area. It is good also as the median of the area of the component surfaces 2a of all the boards K.

In addition, as shown in FIG. 16, when a plurality of electronic circuit boards 2 constitute one board unit 4, the sum of the areas of the component surfaces 2 a of the plurality of electronic circuit boards 2 is added to the board unit 4. The area of the component surface 2a may be used. The board unit 4 shown in FIG. 16 has a configuration in which two electronic circuit boards 2 are connected by a spacer 19.
In addition, even in the case of the substrate unit 4 in a state where a plurality of electronic circuit boards 2 as shown in FIG. 16 are housed in the substrate case 3, the component surface 2a of the substrate unit 4 is obtained by adding the respective component surfaces 2a. It is good also as an area.

The board K having a large area of the component surface 2a tends to be enlarged. Such a substrate K is highly likely to come into contact with hands, tools, etc., for example, when the gaming machine 1 is assembled. Therefore, in the selection example (A-4), an attachment method is selected for the substrate K having a large area of the component surface 2a to realize an appropriate attachment state.
In addition, when screw fixing is employed for the substrate K having a large area, the number of screws increases, which may increase the number of man-hours for attachment work. Therefore, for example, even if the substrate K has a large area, latching or hooking may be employed for the substrate K that is not significantly affected by vibration. In this case, the effect of reducing the number of steps required for the work of attaching the substrate K can be increased.

Various examples of the predetermined position that is the determination threshold are also conceivable. For example:
(B-1) A height position that is X / 2 when the height of the gaming machine 1 is X (B-2) A position that is the uppermost end and a position that is the lowermost end of the target board K Center height position (B-3) Average height position of each center position of the target board K (B-4) Average height position (B-5) game of each top position of the target board K Center of gravity of machine 1

  When (B-1) is adopted as the predetermined position, an appropriate attachment method is selected simply by determining whether or not the target board K is attached to a position higher than half the height of the gaming machine 1 Therefore, the determination can be easily performed.

When (B-2) is adopted as the predetermined position, an appropriate number of boards K can be attached to the gaming machine 1 by screwing, and an appropriate number of boards K can be attached by latching or hooking. 1 can be attached.
A specific example is shown in FIG. FIG. 17 is a diagram schematically showing the positional relationship between the gaming machine 1 and the board K attached to the gaming machine 1. Among the substrates K, the one to be selected for the attachment method is indicated by hatching. That is, in FIG. 17, three of the seven substrates K are targeted. As the predetermined position, the height difference between the uppermost end and the lowermost end of the three target substrates K is set to H1, so that the height is H1 / 2 from the lowermost end.

  As shown in the figure, each board K is disposed above the gaming machine 1. When (B-1) is adopted for such a gaming machine 1, almost all of the boards K are positioned above a predetermined position, and screwing may be unnecessarily adopted as an attachment method. There is. Therefore, by adopting (B-2), it is possible to increase the possibility of selecting an appropriate attachment method in which only a part of the target substrate K is screwed.

A predetermined position when (B-3) is adopted is shown in FIG.
In addition, (C-1) mentioned later is used about the height position where each board | substrate K is attached. That is, a predetermined position is calculated from the center position C of each substrate K.
As shown in the figure, three substrates K, which are substrates K3, K4, and K5, are selected as attachment methods. The height of the center positions C3 and C4 of the boards K3 and K4 disposed above the gaming machine 1 is H2, and the height of the center position C5 of the board K5 disposed below the boards K3 and H4 is H3. According to (B-3), since the predetermined position is the average height of the center position C of the target substrate K, the predetermined position is (2 × H2 + H3) / 3.

  Even when (B-3) is adopted as the predetermined position, the possibility of unnecessarily screwing as an attachment method is eliminated, and only a part of the target substrate K is screwed. Selection of an appropriate attachment method can be realized.

FIG. 19 shows a case where (B-4) is adopted as the predetermined position.
Of the boards K3, K4, and K5 that are selected as attachment methods, the height positions of the upper ends of the boards K3 and K4 disposed above the gaming machine 1 are both H4, and the boards disposed below the boards. The height position of the upper end of K5 is set to H5. Therefore, the predetermined position is (2 × H4 + H5) / 3.

  Even when (B-4) is adopted as the predetermined position, the possibility of unnecessarily screwing as an attachment method is eliminated, and only a part of the target substrate K is screwed. Selection of an appropriate attachment method can be realized.

FIG. 20 shows the case where (B-5) is adopted as the predetermined position.
In the substrates K3, K4, and K5 that are to be selected as attachment methods, the height position of the center of gravity G3 of the substrate K3 is H6, the height of the center of gravity G4 of the substrate K4 is H7, The height position of the gravity center position G5 is set to H8. According to (B-5), since the average height of the gravity center position G of the substrate K is set to a predetermined position, the predetermined position is (H6 + H7 + H8) / 3.

  Even when (B-5) is adopted as the predetermined position, the possibility of unnecessarily screwing as an attachment method is eliminated, and only a part of the target substrate K is screwed. Selection of an appropriate attachment method can be realized.

  In each example in which the predetermined positions are described, the examples in which the boards K3, K4, and K5 are attached to the upper side of the gaming machine 1 are described. However, there is a possibility that they are attached to the lower side. However, even when the boards K3, K4, and K5 are attached to the lower side of the gaming machine 1, the predetermined positions (B-2), (B-3), (B-4), (B By adopting any of (5), it is possible to eliminate the possibility that all the substrates K are attached by latching or hooking, and increase the possibility that necessary parts are attached by screwing.

Further, in order to determine whether or not the target substrate K is positioned above the various predetermined positions, it is necessary to specify the height position of the target substrate K. That is, it is necessary to determine a location to be determined on each substrate K. There are several examples of this. For example:
(C-1) Center position of substrate K (C-2) Center of gravity position of substrate K (C-3) Upper end of substrate K (C-4) Lower end of substrate K (C-5) Position of fixed portion of substrate K The highest position in

  When (C-1) is selected as the position to be determined (determination position) in each substrate K, the position that is the center of the substrate K in the vertical direction and the center in the horizontal direction is set as the determination position. That is, the position is indicated by J1 in FIG. The center position J1 as the determination position can be easily specified. Therefore, it is not necessary to perform complicated calculation or measurement when selecting the attachment method, and the attachment method can be easily selected.

When (C-2) is selected as the determination position for each substrate K, J2 shown in FIG. 21 is the determination position.
The center-of-gravity position J2 of the substrate K may be different from the center position J1 depending on various electronic components mounted on the component surface 2a of the substrate K. For example, if the center position J1 is below the predetermined position when the center of gravity position J2 is shifted upward from the center position J1, and the latch stop or hook stop is selected, the game machine 1 is shaken. There is a possibility that the substrate K will be affected more than expected. As a result, there is a possibility that the engagement portion (latch portion or hook portion) of the substrate K may be worn or damaged.
Therefore, when the center of gravity position J2 is deviated from the center position J1, by selecting a method for attaching the board K based on a comparison between the center of gravity position J2 and a predetermined position, it is less likely to be affected by the shaking of the gaming machine 1. Therefore, it is possible to increase the possibility that an appropriate attachment method is selected.

When (C-3) is selected as the determination position for each substrate K, J3 shown in FIG. 21 is the determination position.
When (C-4) is selected as the determination position of the substrate K, J4 shown in FIG. 21 is the determination position.
The upper end position J3 and the lower end position J4 as determination positions need not be specially measured and can be easily specified. Accordingly, when selecting an attachment method, the predetermined position and the determination position (the upper end position J3 or the lower end position J4) of the substrate K can be easily compared, so that the number of steps can be reduced.

The case where (C-5) is selected as the determination position of the substrate K is shown in FIG.
Each substrate K is provided with a fixing portion. The fixing portion provided on the substrate K is a portion fixed to the gaming machine 1 by various attachment methods. For example, in the case of screwing, the fixing portion is a screw insertion hole 6 as shown in FIG. In the case of latching, the shaft portion 7 and the regulated plate 8 are as shown in FIGS. Further, in the case of hook fastening, it is a portion on the substrate K that is restrained by the hook 17.
FIG. 22 shows the position of the fixing portion I provided on the substrate K. The determination position J5 of the substrate K is the uppermost position among the plurality of fixed portions I on the substrate K.

When the board K receives the influence of the vibration of the gaming machine 1, the magnitude of the influence of the vibration received from the gaming machine 1 is determined according to the portion connected to the gaming machine 1, that is, the height position of the mounting position. For example, even if there are the boards K1 and K2 attached at the same height position, the board K1 and the board K2 that are mounted at the upper position are more susceptible to the vibration of the gaming machine 1.
By setting the position of the uppermost fixed portion I on the substrate K as the determination position J5, it is possible to improve the possibility of selecting an appropriate attachment method based on the sensitivity to the influence of the vibration of the gaming machine 1 Can do.

  As described above, the determination position selected from (C-1) to (C-5) on the substrate to be selected as the attachment method selected from (A-1) to (A-4). By determining whether or not is positioned above the predetermined position determined by any of (B-1) to (B-5), an appropriate attachment method is obtained while obtaining the corresponding effects described above. Can be selected.

  For example, when the attachment method of the board | substrate K is selected based on the combination of (A-2), (B-1), and (C-1), the board | substrate K made into object is the main control board K1 and the production | presentation control board K2. Yes (A-2), depending on whether or not the center position (C-1) of each board is higher than the height position (B-1) of X / 2 from the bottom surface of the gaming machine 1 The attachment method will be selected. When the board is attached so that the center position J1 is higher than X / 2 from the bottom surface, screwing is adopted, and when it is attached so as to be low, latching or hooking is adopted. .

This is intended only for the main control board K1 and the production control board K2 which are the most important boards in the gaming machine 1, and the center position J1 specified by a simple method is a specific position set by a simple method. Therefore, it is very easy to select the mounting method, and it can be realized with a small number of man-hours. That is, a great effect can be obtained with a small number of man-hours.
Moreover, it leads to the reduction of the man-hour concerning a design.

Moreover, as another example, when selecting the attachment method of the board | substrate K based on the combination of (A-1), (B-5), (C-2), all the board | substrates K attached to the gaming machine 1 are selected. As an object, the attachment method is determined depending on whether or not the gravity center position J2 of each board K is located above the gravity center position of the gaming machine 1. That is, when the center of gravity position J2 of the substrate K is located above the center of gravity position of the gaming machine 1, screwing is employed. And about the board | substrate K other than that, a uniform latch stop and a hook stop may be employ | adopted, and the attachment method may be further selected based on the various conditions demonstrated by other embodiment.
Therefore, there is a high possibility that an appropriate attachment method corresponding to the weight balance of the gaming machine 1 is selected for all the boards. Therefore, the possibility that the board K can be prevented from falling off or being damaged by the vibration of the gaming machine 1 becomes very high.

  The same effect can be obtained even when (C-5) is employed instead of (C-2). That is, it is possible to increase the possibility that an appropriate attachment method is selected for each substrate even if the position at the uppermost position of the fixed portion on the substrate K is set as the determination position J5 instead of the center of gravity position J2 of the substrate K. it can.

In addition, a combination of (A-4) and (C-2) may be used. Since the board K on which the area of the component surface 2a is equal to or greater than a certain number tends to include a large number of mounted electronic components, the center position J1 and the center of gravity position J2 are likely to deviate. For such a substrate K, an appropriate attachment method can be easily selected by using the center of gravity position J2 for the determination. In other words, among the boards K in which the area of the component surface 2a is made constant, screw fixing is adopted for the board K whose center of gravity position J2 is above a predetermined position.
This effect can be obtained by selecting any of (B-1) to (B-5).

Moreover, the combination of (A-3) and (C-2) is also good. The heavy substrate K may be affected by the vibration of the gaming machine 1 even if the center of gravity position J2 and the center position J1 are slightly shifted. Therefore, it is determined whether or not the center of gravity position J2 of the target substrate K is located above a predetermined position. That is, among the heavy substrates K, the screwing is employed for the substrates K whose center of gravity J2 is above the predetermined position.
As a result, it is possible to increase the possibility of selecting an appropriate attachment method in consideration of the deviation of the center of gravity position J2 from the center position J1.

Note that a method for attaching the substrate K may be selected by using a plurality of combinations simultaneously.
For example, the attachment method of the main control board K1 and the effect control board K2 is determined by the combination of (A-2), (B-1), and (C-1), and (A-3) and (B-5). , (C-2), the attachment method for the heavy substrate K among the substrates K other than the main control substrate K1 and the effect control substrate K2 may be determined.
That is, the main control board K1 and the effect control board K2 are fixed by screwing when the center position J1 of the board K is higher than half the height of the gaming machine 1. And about the board | substrates K other than the main control board K1 and the production | presentation control board K2, when the gravity center position J2 of the board | substrate K is located above the gravity center position of the gaming machine 1, it is fixed by screwing.

In the present embodiment, the selection of the attachment method for the substrate K as the electronic circuit board 2 or the substrate unit 4 has been described. However, the attachment method may be selected only for the substrate unit 4.
For example, the electronic circuit board 2 that is not accommodated in the substrate case 3 is attached by screwing regardless of the attachment position, and the substrate unit 4 that is accommodated in the substrate case 3 is attached by the screw unit. It is good also as selecting the attachment method according to the various determinations mentioned above according to the attachment position.

  When the substrate unit 4 is worn or damaged, there is a high possibility that the substrate case 3 may be worn or damaged. On the other hand, the electronic circuit substrate 2 not stored in the substrate case 3 is worn or damaged. In such a case, the electronic circuit board 2 itself may be worn or damaged, and may not operate normally. That is, there is a circumstance that the electronic circuit board 2 that is not housed in the board case 3 is at a high risk of being worn or damaged, and is therefore desired to be avoided as much as possible.

Therefore, the electronic circuit board 2 not stored in the board case 3 is firmly fixed to the gaming machine 1 by screwing.
On the other hand, the electronic circuit board 2 accommodated in the board case 3 is appropriately latched and hooked based on the selection of the mounting method described above, thereby reducing the number of parts and the number of assembly steps.
At this time, for example, when (B-2) is adopted as the predetermined position, “the center height position of the position of the uppermost end and the position of the lowermost end of the target substrate K” is “targeted”. It is good also as a center height position of the position used as the uppermost end and the position used as the lowest end among the board | substrate units 4.
Thereby, the predetermined number is appropriately set only for the board unit 4 that selects the attachment method to the gaming machine 1, and the possibility that an appropriate attachment method is selected can be increased.
Similarly, when (B-3) or (B-4) is adopted as the predetermined position, the predetermined position is determined in the board K excluding the electronic circuit board 2 that is not stored in the board case 3. May be.

  In this embodiment, an example in which latching or hooking is employed for the substrate K attached below the predetermined position has been described. However, in consideration of the environment and conditions for attaching the substrate K, the description will be given later. By applying any of the various embodiments, it may be determined whether to use screwing, latching, or hooking.

As described above, in the gaming machine 1 to which a plurality of board units 4 in which the electronic circuit board 2 is housed in the board case 3 are attached, the plurality of board units 4 are arranged at predetermined positions ( A first substrate unit having a fixing means (various fixing mechanisms such as a fixing portion I) above (any of (B-1) to (B-5)) and a fixing means below a predetermined position. The first substrate unit uses first fixing means (screw insertion hole 6) such as a screw fixing mechanism as the fixing means, and the second substrate unit uses the first fixing means as the fixing means. For example, a second fixing means such as a latching mechanism or a hooking mechanism (a portion on the substrate K that is restrained by the shaft portion 7, the regulated plate 8, or the hook 17) is used.
The first fixing means requires a tool such as a driver for releasing the fixing, and the second fixing means does not require a tool for releasing the fixing.
Thereby, for example, the board K is mounted on the upper side that is easily affected by the vibration of the gaming machine 1 and has a fixing means (for example, a fixing portion I as a part of the fixing mechanism) above a predetermined position. About the board | substrate K, a screw stop is employ | adopted suitably and it attaches to the game machine 1 firmly, and abrasion and damage to the board | substrate K are suppressed.
For some of the other substrates K, latching and hooking are employed, thereby reducing the number of man-hours required for attachment work.
A method of attaching each substrate K is selected based on the above (A-1) to (A-4), (B-1) to (B-5), and (C-1) to (C-5). As a result, the number of design man-hours can be reduced and the above (A-1) to (A-4), (B-1) to (B-5), and (C-1) to (C-5). Various effects mentioned in the description can be obtained.

In addition, the gaming machine 1 includes a main control board K1 as the main control means and an effect control board K2 as the sub control means as the board unit 4, and communication means capable of unilateral communication from the main control means to the sub control means. One of the main control means and the sub control means may be a first substrate unit, and the other may be a second substrate unit.
Thereby, possibility that an appropriate attachment method will be selected with respect to the main control board K1 and the production | presentation control board K2 which are the board | substrates K important for the game machine 1 can be raised.

Further, the main control board K1 as the main control means provided in the gaming machine 1 is the first board unit, the effect control board K2 as the sub control means is the second board unit, and the first board unit is screwed. The second fixing unit may be fixed to the gaming machine 1 by using, for example, a latching mechanism or a hooking mechanism without using the first fixing unit.
Thereby, the main control board K1 which is the more important board K among the main control board K1 and the effect control board K2 is attached to the gaming machine 1 by screwing. Therefore, it is possible to prevent the main control board K1 from being worn or damaged due to vibration or shaking.

Furthermore, as a predetermined position, when the height position of X / 2 when the height of the gaming machine is X, that is, when the above-described (B-1) is adopted, the target board K is the gaming machine 1 Since it is possible to select an appropriate mounting method simply by determining whether or not it can be mounted at a position higher than half the height, it is possible to easily design and contribute to a reduction in design man-hours. .

[4-2. Second Embodiment]
Some of the boards K attached to the gaming machine 1 are arranged so as to overlap with other boards K.
An example is shown in FIG.

The gaming machine 1 is provided with a first arrangement recess 20 to which the substrate K6 is attached. On the bottom surface 20a of the first arrangement recess 20, a second arrangement recess 21 to which the substrate K7 is attached is provided.
When the board K6 and the board K7 are attached to the gaming machine 1, as shown in the drawing, the board K6 is attached so as to overlap the board K7 or cover the board K7. FIG. 24 shows a state where both the boards K6 and K7 are attached to the gaming machine 1.

When it becomes necessary to remove the substrate K7, the substrate K7 cannot be removed unless the substrate K6 is removed.
Further, when a connector terminal is provided on the board K7, the board K6 needs to be removed when the connector is inserted into and removed from the connector terminal.

Therefore, in the present embodiment, latching or hooking is selected as the method for attaching the substrate K6.
FIG. 25 shows an example in which the board K7 is attached to the gaming machine 1 by screwing and the board K6 is attached to the gaming machine 1 by latching.

The bottom surface 21a of the second disposition recess 21 provided in the gaming machine 1 is provided with screw holes 21b into which the tips of the screws 300 are inserted at substantially four corners.
Two latch members 22 are provided on the peripheral edge portion of the first arrangement recess 20 provided in the gaming machine 1. The latch member 22 includes a columnar base portion 22a and a holding portion 22b protruding to the side of the column.
The base portion 22a can be rotated in the direction around the axis of the cylinder, and the holding portion 22b is also rotated with respect to the center of the cylinder along with the rotation. That is, the direction in which the holding portion 22b protrudes from the cylinder is variable.
Near the four corners of the substrate K7, screw insertion holes K7a through which the screws 300 are inserted are provided.

When attaching the boards K6 and K7 to the gaming machine 1, first, the board K7 is attached to the placement recess 21 by the screw 300, and then the board K6 is fitted into the placement recess 20.
The base portion 22a of the latch member 22 is rotated in a state in which the substrate K6 is fitted in the arrangement recess 20, and the holding portion 22b of the latch member 22 is protruded in a direction along the peripheral edge of the arrangement recess 20 from the arrangement recess 20. By changing to a state where the substrate K6 protrudes toward the center, the substrate K6 is prevented from falling off from the first arrangement recess 20.

FIG. 26 shows a state in which the boards K6 and K7 are attached to the gaming machine 1. As shown, the substrate K7 cannot be touched as long as the substrate K6 is attached. That is, when any work (such as replacement of the substrate K7, insertion / extraction of a connector, or pressing of a button terminal) is required for the substrate K7, it is necessary to remove the substrate K6.
For example, if the gaming machine 1 is stored in the position of the board K7 with the board K that is likely to be the target of unauthorized operation, the effect of preventing unauthorized operation can be enhanced.

  According to the configuration shown in FIGS. 25 and 26, when some work is required for the substrate K7, it becomes necessary to remove the substrate K6. However, since no tool is required to attach or remove the substrate K6, various operations on the substrate K7 can be performed by removing the substrate K6 by a simple operation.

Note that the board K7 is attached by the screw 300 only as an example, and may be attached by latching or hooking. For example, when there is a high possibility that the replacement work of the substrate K7 will occur, the substrate K7 may be attached by latching or hooking similarly to the substrate K6. Thereby, the removal operation | work of the board | substrate K7 also becomes easy.
Further, the substrate K7 is surrounded by five surfaces among the six surfaces by the bottom surface 21a and the wall surface of the second arrangement recess 21, and the remaining one surface is covered by the substrate K6, so that all six surfaces are surrounded. Therefore, it is difficult for the board K7 to fall out of the gaming machine 1. This is also the reason why there is no problem even if latching or hooking is selected as the method for attaching the substrate K7.

In the example shown in FIGS. 25 and 26, the example in which the substrate K7 is completely covered with the substrate K6 is shown. However, even if the substrate K6 is disposed so as to cover only a part of the substrate K7. Good.
Even if the substrate K7 is easily subject to unauthorized substrate replacement, it is necessary to remove the substrate K6 in order to replace the substrate K7 because the substrate K7 is partly covered with the substrate 6. Therefore, it is possible to obtain fraud prevention effects.

  The first placement recess 20 and the second placement recess 21 provided in the gaming machine 1 may be a recess formed on a mounting base for mounting the substrate K, and may be surrounded by a plurality of members (components). It may be a recess formed by. Of course, a part of the wall surface or bottom surface forming the recess may be a part of the outer frame 104 or a part of the front frame of the ball game machine 100, or the wall part of the main body case 201 of the revolving game machine 200. Or a part of the front panel.

Members required only for attaching the substrate K are formed by a member other than the member provided only for attaching the substrate K, in which part of the wall surface and the bottom surface of the first arrangement recess 20 and the second arrangement recess 21 is formed. Can be reduced.
Further, by forming all the wall surfaces and bottom surfaces of the first placement recess 20 and the second placement recess 21 without using a member only for mounting the substrate K, members necessary only for mounting the substrate K are eliminated. Therefore, it is possible to reduce the number of parts and the cost.

As described above, in the gaming machine in which a plurality of board units 4 in a state where the electronic circuit board 2 is housed in the board case 3 are attached, the plurality of board units 4 are the first board units (board K7). And a second substrate unit (substrate K6) attached in a state of covering at least a part of the first substrate unit. The second substrate unit is a second means such as a latching mechanism or a hooking mechanism as a fixing means. A fixing means is used, and at least one substrate unit other than the second substrate unit uses a first fixing means such as a screwing mechanism different from the second fixing means as the fixing means, and the first fixing means is fixed A tool such as a driver is required for release, and the second fixing means does not require a tool for release.
Thereby, when the operation | work with respect to a 1st board | substrate unit is needed, since the removal operation | work of a 2nd board | substrate unit is simplified, an operation man-hour can be reduced.

In the first substrate unit, the first fixing means may be used as the fixing means.
For example, when the work with respect to the first board unit is a connector insertion / extraction work, etc., the first board unit is provided with a first fixing means such as a screwing mechanism, so that rattling or the like during the work can be suppressed. It becomes possible to improve ease.

[4-3. Third Embodiment]
The gaming machine 1 is attached with one or more movable objects. The movable body accessory is often used mainly to improve game play, and for example, a design based on the theme or material set in the gaming machine 1 is applied. Specifically, a movable body accessory provided with a tire design provided on the gaming machine 1 with a car motif, or a horse provided with a horse design provided on the gaming machine 1 with a horse racing motif. It is a body accessory.

These movable body accessories are used for the effect of enhancing the gameability by moving between predetermined positions during the game.
The movable body accessory is provided with a power source such as a motor for movement. Since a power source such as a motor vibrates during operation, it can be a vibration source that affects other members. In addition, the movable object itself can be a vibration source due to the effect of trembling in small steps.

Such a vibration source (such as a motor or movable body accessory itself) may adversely affect other members. In particular, there is a high possibility that the power source having a high operation rate and a large-scale power source because the performance is frequently performed will have a great influence.
Examples of adverse effects on other members include, for example, dropping off of the substrate K attached by latching, wear of the substrate K due to vibration, and generation of noise due to contact between the substrate K and other members.

Therefore, in the present embodiment, an example will be described in which the substrate K attachment method is appropriately selected according to the distance from the vibration source of the movable body accessory.
However, the distance between the vibration source and the substrate K is the length of the shortest transmission path D when vibration from the vibration source is transmitted to the substrate K.

FIG. 27 shows the positional relationship between the movable body accessory 23 attached to the gaming machine 1 and the motor 24 for moving the movable body accessory 23 and the substrate K.
The gaming machine 1 has an arrangement surface 25 for attaching the substrates K8 and K9. A plurality of board attachment members 26 are arranged on the arrangement surface 25. In the example shown in the figure, substrates K8 and K9 are attached to two substrate attachment members 26, respectively.

A movable object 23 and a motor 24 are attached in the vicinity of the substrates K8 and K9.
The movable body accessory 23 includes a cylindrical portion 23a connected to the motor 24, a movable portion 23c that is a portion that moves by obtaining the power of the motor 24, and a portion that connects the cylindrical portion 23a and the movable portion 23c. The connecting portion 23b is provided.
The cylindrical portion 23a includes a mechanism for transmitting power from the motor 24 to the movable portion 23c.
The movable portion 23c can move with the connecting portion 23b as a fulcrum.
Although the movable portion 23c has a cylindrical shape in the drawing, the movable portion 23c may have a design shape so that the player can directly recognize it, or another member having the design may have a tip. It may be attached to.

FIG. 27 shows the shortest transmission paths D1 and D2 when vibration is transmitted from the motor 24 as a vibration source to the substrates K8 and K9.
The length of the transmission path D1 between the motor 24 and the substrate K8 is the shortest distance between the motor 24 and one end of the substrate mounting member 26 for the substrate K8 and the shortest distance between one end of the substrate mounting member 26 and one end of the substrate K8. It is said that the length.
Similarly, the length of the transmission path D2 between the motor 24 and the substrate K9 is set such that the shortest distance between the motor 24 and one end of the substrate mounting member 26 for the substrate K9, and the shortest distance between one end of the substrate mounting member 26 and one end of the substrate K9. It is the added length.

  When the transmission path D1 and the transmission path D2 are compared, the transmission path D2 is shorter as illustrated. Accordingly, the substrate K9 is closer to the motor 24 than the substrate K8.

Another example is shown in FIG.
As shown in the drawing, on the arrangement surface 25 of the gaming machine 1, substrates K10 and K11, a movable body accessory 23, and a motor 24 are arranged.
The length of the shortest transmission path D3 when the vibration of the motor 24 is transmitted to the substrate K10 is shorter than the length of the shortest transmission path D4 when the vibration of the motor 24 is transmitted to the substrate K11 as shown in the figure. .
In this example, the transmission path is short although the linear distance is long. That is, although the linear distance is shorter for the substrate K11 than for the substrate K10, the transmission path length through which vibration from the motor 24 is transmitted is shorter for the substrate K10 than for the substrate K11.

As shown in FIGS. 27 and 28, the vibration of the vibration source is attenuated as the transmission path D is longer. Therefore, the board K having the short reach route D is easily affected by vibration from the vibration source (motor 24), and therefore it is desirable that the board K be attached to the gaming machine 1 without looseness by screwing.
Further, since the substrate K having a long transmission path D is not easily affected by the vibration source, it is possible to improve work efficiency and reduce the number of parts by adopting latching or hooking.

  In addition, by selecting the substrate K attachment method based on the length of the vibration transmission path D, not the linear distance between the substrate K and the vibration source, the substrate K attachment method that takes into account the substantial vibration effect is provided. Since it is possible to select, when it is desired to use a part of the board K as a method of attaching the board K and a part of the latch or hook as an attachment method, an appropriate attachment method can be selected.

Next, an example in which the substrate K is affected by a plurality of vibration sources will be described with reference to FIG.
The gaming machine 1 shown in FIG. 29 has a substrate K12 that is attached to the placement surface 25 via a substrate attachment member 26, and two motors 24A and 24B.

The substrate K12 is affected by vibration from both the motors 24A and 24B.
The shortest transmission path D5 when the vibration of the motor 24A is transmitted to the substrate K12 is the shortest distance between the motor 24A and one end of the substrate mounting member 26, and the shortest distance between one end of the substrate mounting member 26 and one end of the substrate K12. The length is added.
The shortest transmission path D6 when the vibration of the motor 24B is transmitted to the substrate K12 is the shortest distance between the motor 24B and one end of the substrate mounting member 26, and one end of the substrate mounting member 26 and one end of the substrate K12. The length is the sum of the shortest distances.

The evaluation of the influence of the vibrations of the motors 24A and 24B on the substrate K12 is made by adding the influences received from the respective motors 24A and 24B.
For example, when the influence of the vibration that the substrate K12 receives from the motor 24A is E1, and the influence of the vibration that is received from the motor 24B is E2, the influence of the motors 24A and 24B on the substrate K12 is (E1 + E2).

At this time, the influence of the vibration that the substrate K12 receives from the motor 24A is based on the length of the transmission path D5. The higher the influence of vibration that the substrate K12 receives from the motor 24A, the higher E1 becomes. Specifically, E1 becomes a higher numerical value as the length of the transmission path D5 is shorter.
Similarly, E2 becomes higher as the influence of vibration that the substrate K12 receives from the motor 24B is higher, that is, as the length of the transmission path D6 is shorter.
The value of (E1 + E2) indicating the height of the influence received from the motors 24A and 24B as a plurality of vibration sources becomes a larger value as the influence is larger.

  When a plurality of substrates K and a plurality of vibration sources are arranged in the gaming machine 1, for example, as described above, it is desirable to add and evaluate the influence received from the plurality of vibration sources for each substrate K. . As a result, a method of attaching the substrate K according to the situation is appropriately selected, for example, screwing is adopted for the substrate K which is affected by a plurality of vibration sources and is greatly influenced by the overall.

Another example in which the substrate K is affected by a plurality of vibration sources will be described with reference to FIG.
As in the previous examples, the boards K13 and K14 are each attached to the arrangement surface 25 of the gaming machine 1 via the board attachment member 26.
The substrates K13 and K14 are affected by vibration from the plurality of motors 24C and 24D, respectively.

The shortest transmission path D7 when the vibration of the motor 24C is transmitted to the substrate K13 is shorter than the shortest transmission path D8 when the vibration of the motor 24C is transmitted to the substrate K14.
The shortest transmission path D9 when the vibration of the motor 24D is transmitted to the substrate K13 is longer than the shortest transmission path D10 when the vibration of the motor 24D is transmitted to the substrate K14.
That is, the influence of the vibration of the motor 24C is more susceptible to the substrate K13 than the substrate K14, and the influence of the vibration of the motor 24D is more susceptible to the substrate K14 than the substrate K13.

In such a case, it is assumed that the operating rate of the motor 24C is higher than that of the motor 24D. For example, consider a situation where the motor 24C operates frequently but the motor 24D rarely operates.
In such a situation, the substrate K13 that is easily affected by the motor 24C having a high operating rate can be considered as the substrate K that is more easily affected by the vibration source (motors 24C and 24D) than the substrate K14.

In the gaming machine 1, a plurality of substrates K and a plurality of vibration sources (for example, motors 24C and 24D) are arranged, and when each substrate K is affected by each vibration source, the substrate K and the vibration source It is desirable not only to consider the shortest transmission path D but also to evaluate the influence from the vibration source for each substrate K in consideration of the operating rate of the vibration source.
In the above example, it is desirable that the board K13 is attached to the gaming machine 1 by screwing. When the operating rate of the motor 24D is extremely low, it is possible to select latching or hooking as a method of attaching the board K14 to the gaming machine 1.
Thus, by considering the operating rate of the vibration source, it is possible to select a method for attaching the substrate K in accordance with the actual situation.

In addition to the operating rate of the vibration source, it is possible to select a mounting method for the substrate K that is more realistic in consideration of the vibration intensity of the vibration source. For example, when the motor 24 as a vibration source is moved, the larger the motor 24 is, the larger the vibration is and the greater the influence on the substrate K is. Further, the influence is exerted on the substrate K which is far away.
Therefore, it is possible to select an appropriate method for attaching the substrate K by evaluating the influence of vibration for each substrate K in consideration of the magnitude of vibration for each vibration source.

  27, FIG. 28, FIG. 29, and FIG. 30, the example in which the arrangement surface 25 is configured by one surface has been described, but it may be configured by a plurality of surfaces or a plurality of members. That is, a configuration in which vibration from the motor 24 is transmitted to the substrate K through a plurality of members may be employed.

Further, in the above-described example, the influence of the substrate K8 (K9, K10, K11, K12, K13, K14) from the motor 24 (24A, 24B, 24C, 24D) as the vibration source is described on the substrate K8 (K9, K10, K11, K12, K13, K14) and the influence of vibration were evaluated based on the shortest transmission path of the vibration source, but other examples are also conceivable.
For example, when the substrate K8 (K9, K10, K11, K12) is the substrate unit 4 accommodated in the substrate case 3, it is arranged inside the substrate case 3 instead of the shortest transmission path to one end of the substrate unit 4. The influence of vibration may be evaluated based on the shortest transmission path to one end of the electronic circuit board 2 that has been made, or the influence of vibration may be evaluated based on the transmission path to the approximate center of the electronic circuit board 2. Also good.

Note that the substrate K having the shortest distance of the vibration path D may be specified for each vibration source, and screwing may be employed as a method of attaching the specified substrate K. For example, referring to FIG. 30, the board K13 closest to the motor 24C employs screwing in consideration of being most susceptible to the vibration of the motor 24C. The board K14 closest to the motor 24D employs screwing in consideration of being most susceptible to the vibration of the motor 24D.
Thus, by specifying the closest board K for each motor 24 and using screwing, even in the gaming machine 1 provided with a plurality of vibration sources and a plurality of boards K, the mounting method can be easily set. Selection can be made.

As described above, the gaming machine 1 includes the movable body accessory 23 and the board unit 4 in which the electronic circuit board 2 is housed in the board case 3. The substrate unit 4 includes a first substrate unit closest to a vibration source (such as a motor) of the movable article 23 and a second substrate unit different from the first substrate unit. The distance to the vibration source can be expressed by, for example, the length of the vibration transmission path D.
The first substrate unit (for example, the substrate K9 with respect to the substrate K8) uses first fixing means such as a screwing mechanism as the fixing means, and the second substrate unit (for example, substrate K8 with respect to the substrate K9) serves as the first fixing means. Different from the fixing means, for example, a second fixing means such as a latching mechanism or a hooking mechanism is used. The first fixing means requires a tool such as a driver for releasing the fixing, and the second fixing means does not require a tool for releasing the fixing.
Thereby, since an attachment method is appropriately selected according to the distance from the vibration source to the substrate K, it is possible to prevent the substrate K from being worn or damaged, and to shorten the working time.

In addition, the gaming machine 1 includes a main control board K1 as the main control means and an effect control board K2 as the sub control means as the board unit 4, and communication means capable of unilateral communication from the main control means to the sub control means. One of the main control means and the sub control means may be a first substrate unit, and the other may be a second substrate unit.
Thereby, possibility that an appropriate attachment method will be selected with respect to the main control board K1 and the production | presentation control board K2 which are the board | substrates K important for the game machine 1 can be raised.

Further, the vibration source may be a motor for moving the movable body accessory.
This makes it easy to specify the vibration source. That is, since the position of the vibration source can be grasped only by grasping the position of the motor, the selection of the attachment method of each substrate K is simplified.

Furthermore, the substrate unit having the shortest path length through which the vibration from the vibration source is transmitted may be the first substrate unit closest to the vibration source.
Since the length of the path (transmission path D) when vibration is transmitted from the vibration source to the substrate K is used as the distance between the substrate K and the vibration source, the substrate K that is actually susceptible to vibration from the vibration source. Is attached by screwing, and the wear and damage of the substrate K can be prevented.

[4-4. Fourth Embodiment]
The board K attached to the gaming machine 1 may be heavy or light. The influence of vibration during transportation or operation of the gaming machine 1 may vary depending not only on the position where the substrate K is attached as in the previous example, but also on the weight of the substrate K.

Therefore, in this embodiment, an example in which an attachment method is appropriately selected according to the weight of the substrate K will be described.
Compared to the case where the board K is attached to the gaming machine 1 by screwing, when the board K is attached by latching or hooking, wear on the fixed portion (that is, the latching part or hook part) of the gaming machine 1 occurs. Cheap.
Furthermore, since the latch portion and the hook portion are often formed of a resinous member from the viewpoint of cost, they are easily worn from the surface of the material. Therefore, there is a risk that rattling or noise due to wear may be a problem.
Therefore, in this embodiment, the heavier substrate K is used for screwing. That is, when the substrate K has a predetermined weight or more, screwing is adopted as an attachment method, and when the weight is less than a predetermined value, latching or hooking is adopted.

Here, examples of the predetermined weight will be described below.
(D-1) Y-gram (D-2) Z% of the weight of the gaming machine 1 with all members attached
(D-3) Average weight of target board K (D-4) Average weight of main control board K1 and effect control board K2

When (D-1) is selected as the predetermined weight, for example, a constant value Y may be set to the predetermined weight regardless of the type of the gaming machine 1.
Since the Y-gram as the predetermined weight determined in this way does not need to consider the characteristics of each gaming machine 1, man-hours are required for determining a reference (that is, a specific weight) when selecting an attachment method. There is no need to break down. Therefore, the design man-hour can be reduced.
In addition, it is not necessary to consider the mounting method for each substrate K, and the mounting method is determined simply by comparing with a uniformly set standard (predetermined weight). It can contribute to reduction.

When (D-2) is selected as the predetermined weight, the predetermined weight can be changed according to the total weight of the gaming machine 1.
For example, it is conceivable that the way the gaming machine 1 shakes when the gaming machine 1 is carried on a truck bed or the like varies depending on the weight of the gaming machine 1. That is, the substrate K and the gaming machine 1 are worn according to the difference in the way of shaking. In such a case, if (D-2) is adopted, an appropriate threshold value can be determined according to the weight of the gaming machine 1, and the board K that needs to be firmly fixed is screwed to the gaming machine. 1 can be fixed.

When (D-3) is selected as the predetermined weight, among the plurality of boards K attached to the gaming machine 1, screw fastening is selected for an appropriate number of boards K and attached to the gaming machine 1. .
The target substrate K is a substrate K for which an attachment method is selected as in (A-1) and (A-2) as described above.
When all the boards K are attached to the gaming machine 1 by latching or hooking, the contact area and the contact location between the board K and the locking part (latch part or hook part) increase, so wear due to vibration from the vibration source. Therefore, there is a high possibility that a portion where the fixing force is reduced is generated.
However, according to (D-3), not all the substrates K are attached by screwing, and all the substrates K are not attached by latching or hooking. That is, since at least one board K is attached to the gaming machine 1 by screwing, it is possible to suppress the occurrence of problems such as a decrease in fixing force.

It is also conceivable to use a value obtained by multiplying the average weight of the substrate K by a coefficient as the predetermined weight. According to this, by setting the coefficient higher, it is possible to reduce the man-hours required for mounting the substrate K by reducing the number of screwing points and increasing the number of latching and hooking points.
On the other hand, by setting the coefficient low, it is possible to increase the number of screwing points and suppress the play of the substrate K and the occurrence of wear.

  Then, by selecting the screwing for the heavy substrate K which is considered to be easily affected by vibration, it is possible to appropriately prevent problems caused by the influence of vibration.

  When (D-4) is selected as the predetermined weight, one of the main control board K1 and the production control board K2 as the important board K attached to the gaming machine 1 is screwed to the gaming machine 1 Attached to. As a result, a simple method of selecting screw fastening as the heavier attachment method of the main control board K1 and the effect control board K2, that is, the attachment of the main control board K1 and the effect control board K2 with less man-hours. An appropriate method can be selected.

Further, as compared with the main control board K1 and the production control board K2 that are relatively large and easy to be weighted, the board K that is as heavy as that can be firmly fixed to the gaming machine 1 by screwing.
Thereby, since the predetermined | prescribed weight used as the reference | standard of the attachment method can be determined with a simple method, a man-hour can be reduced.
In addition, since the main control board K1 and the production control board K2 are relatively easy to increase in weight, a weight obtained by adding 1 g to the lighter weight of the main control board K1 or the production control board K2 is set as a predetermined weight. Also good. Thereby, with respect to a board that is as heavy as the main control board K1 and the effect control board K2, screwing is adopted and attached to the gaming machine 1, and the occurrence frequency of defects due to the influence of vibration can be suppressed. Further, the number of assembling steps can be reduced by adopting latching or hooking for the substrate K lighter than a predetermined weight.

  Further, the lighter weight of the main control board K1 and the effect control board K2 may be a predetermined weight. In this case, both the main control board K1 and the effect control board K2 are attached to the gaming machine 1 by screwing.

In the above example, the substrate K is the selection target of the attachment method to the gaming machine 1. That is, not only the substrate unit 4 accommodated in the substrate case 3 but also the electronic circuit substrate 2 not accommodated in the substrate case 3 was selected as an attachment method.
However, when the substrate unit 4 is damaged, there is a high possibility that the substrate case 3 may be damaged. On the other hand, when the electronic circuit board 2 not stored in the substrate case 3 is worn or damaged. In such a case, the electronic circuit board 2 itself may be worn out or damaged, and may not operate normally. That is, there is a circumstance that the electronic circuit board 2 that is not housed in the board case 3 is at a high risk of being worn or damaged, and is therefore desired to be avoided as much as possible.

  Therefore, the electronic circuit board 2 that is not stored in the board case 3 is attached to the gaming machine 1 by screwing regardless of the weight, and the electronic circuit board 2 is stored in the board case 3. The above determination may be performed when the substrate unit 4 in the state is attached.

For example, when (D-3) is adopted as the predetermined weight, the “average weight of the target substrate K” may be set as “the average weight of the target substrate unit 4”.
Thereby, a predetermined weight is appropriately set only for the board unit 4 that selects the attachment method to the gaming machine 1, and the possibility that an appropriate attachment method is selected can be increased.

In the above-described example, the “predetermined weight” as the same threshold value is applied to all the substrates K. However, the “predetermined weight” may be changed depending on the substrate K.
For example, the board K may have one electronic circuit board 2 as shown in FIG. 9, or may have two integrated electronic circuit boards 2 as shown in FIG. There is also.
Accordingly, an example in which the “predetermined weight” is changed between the board K15 having one electronic circuit board 2 and the board K16 having the board unit 4 in which a plurality of electronic circuit boards 2 are integrated. Will be explained.

For example, when the above (D-1) is adopted as the predetermined weight, the predetermined weight is set to Y gram for the substrate K15, and the predetermined weight is set to (Y ×) for the substrate K16. 0.5) Gram.
An example of the substrate K16 is the substrate unit 4 shown in FIG.
As shown in FIG. 16, the substrate unit 4 in a state where a plurality of electronic circuit boards 2 are stacked has a center of gravity away from the surface to be attached. When such a board unit 4 is attached to the gaming machine 1 by latching or hooking, the load applied to the latching part or the hooking part is likely to increase, and it is easy to wear even when vibration occurs. Since the degree of fixing to the gaming machine 1 is looser than that of screwing, the electronic circuit board 2 tends to be more unstable than the single board K.

With respect to the board unit 4 that is likely to be unstable when the electronic circuit board 2 is overlaid, a predetermined weight is reduced (Y × 0.5). The number of substrates K that are firmly fixed to the gaming machine 1 can be increased.
Therefore, it is possible to select an appropriate attachment method according to the state of the substrate K.

The predetermined weight may be set to 0 gram for the substrate K16 having the substrate unit 4 in which the plurality of electronic circuit substrates 2 are integrated. That is, when the substrate K has the substrate unit 4 in which a plurality of electronic circuit substrates 2 are integrated, unscrewing may be employed unconditionally.
Thereby, all the substrates K16 that are likely to be unstable are attached to the gaming machine 1 by screwing, and it is possible to prevent problems such as wear and generation of vibration noise.

As described above, a plurality of board units 4 in a state in which the electronic circuit board 2 is housed in the board case 3 are attached to the gaming machine 1. The plurality of substrate units 4 include a first substrate unit having a weight greater than or equal to a predetermined weight and a second substrate unit having a weight less than a predetermined weight. Any of (D-1) to (D-4) described above can be employed as the predetermined weight.
The first substrate unit uses first fixing means such as a screwing mechanism as fixing means, and the second substrate unit differs from the first fixing means as first fixing means such as a latching mechanism and a hooking mechanism. Two fixing means are used.
The first fixing means requires a tool such as a driver for releasing the fixation, and the second fixing means does not require a tool for releasing the fixation.
As a result, the board K that is likely to become unstable when attached with a heavy weight is attached to the gaming machine 1 using screwing. Accordingly, it is possible to prevent a problem that the board K is worn or damaged due to vibrations of the gaming machine 1 and the board K is light in weight and not affected by vibration or the like. Since latching and hooking are adopted and attached to the gaming machine 1, the number of work steps can be reduced.

The substrate unit 4 further includes a third substrate unit (substrate K16) having a plurality of electronic circuit boards 2 and having a weight less than a predetermined weight. The third substrate unit uses the first fixing means as the fixing means. May be.
Even if the weight is less than a predetermined value, if the electronic circuit board 2 is a board K that is stacked a plurality of times via spacers 19 (see FIG. 16) or the like, the position where the center of gravity is high (separated from the surface to be attached) Position). Since such a board | substrate K tends to become unstable when it is attached, it is considered that it is attached to the gaming machine 1 by screwing. As a result, it is possible to prevent problems such as wear of the substrate K and generation of vibration noise.

Further, the gaming machine 1 includes a main control board K1 as a main control means and an effect control board K2 as a sub control means as the board unit 4, and communication means capable of unilateral communication from the main control means to the sub control means. One of the main control means and the sub control means may be a first substrate unit, and the other may be a second substrate unit.
Thereby, it is possible to select an appropriate attachment method for the main control board K1 and the effect control board K2, which are boards K important for the gaming machine 1.

Furthermore, a main control board K1 as a main control means provided in the gaming machine 1 is a first board unit, an effect control board K2 as a sub-control means is a second board unit, and the first board unit is a screw. The second fixing unit may be fixed to the gaming machine 1 by using a first fixing unit such as a stopping mechanism, and the second board unit may be fixed to the gaming machine 1 by using, for example, a latching mechanism or a hooking mechanism without using the first fixing unit. .
Thereby, the main control board K1 which is the more important board K among the main control board K1 and the effect control board K2 is attached to the gaming machine 1 by screwing. Therefore, it is possible to prevent the main control board K1 from being worn or damaged due to vibration or shaking.

In addition, the predetermined weight may be an average weight per one board unit 4 attached to the gaming machine 1. Specifically, (D-3) described above may be employed as the predetermined weight.
As a result, not all the substrates K are attached by screwing, and all the substrates K are not attached by latching or hooking. That is, since at least one board K is attached to the gaming machine 1 by screwing, it is possible to suppress the occurrence of problems such as a decrease in fixing force.

[4-5. Fifth embodiment]
Some boards K attached to the gaming machine 1 are provided with connector terminals into which connectors for transmitting and receiving various signals to and from other boards K and the like are inserted. Some connectors inserted into the connector terminals are not removed once after being inserted at the time of manufacture, while others are removed and inserted again during maintenance or the like.
When the connector is inserted into and removed from the connector terminal, a load is applied to the connector portion and the locking portion that locks the board K to the gaming machine 1 (that is, a screw, a latch portion, or a hook portion).
For example, if an excessive load is applied to the locking portion, the latch portion or the hook portion may be damaged or worn.

Therefore, in the present embodiment, an example in which an attachment method to the gaming machine 1 is appropriately selected according to the number of connector terminals provided on the board K will be described.
FIG. 9A shows the electronic circuit board 2 on which six connector terminals 27 are arranged. The board K on which the electronic circuit board 2 is disposed inside the board case 3 is referred to as a board K17.
FIG. 31 shows the electronic circuit board 2 on which three connector terminals 27 are arranged. The board K on which the electronic circuit board 2 is disposed inside the board case 3 is referred to as a board K18.

  Whether the board K17 or the board K18 is to be screwed as a method of attaching to the gaming machine 1 or to be latched or hooked is determined by the number of connector terminals 27 arranged on the electronic circuit board 2. Specifically, when the number of connector terminals 27 arranged on the electronic circuit board 2 is a predetermined number or more, screwing is employed, and when the number is less than the predetermined number, latching or hooking is employed. Therefore, according to the present embodiment, the board K17 is more likely to employ screwing as an attachment method than the board K18, and the board K18 is more likely to employ latching or hooking as an attachment method than the board K17. Of course, depending on the predetermined number, any substrate K may be attached by screwing, or any substrate K may be attached by hooking.

Here, some examples will be given with respect to the predetermined number of connector terminals serving as determination criteria.
(E-1) F (E-2) Number of average connector terminals 27 of the target board K (E-3) Average number of connector terminals of the main control board K1 and the production control board K2 (E-4) The smaller of the number of connector terminals 27 on the main control board K1 and the number of connector terminals 27 on the effect control board K2

When (E-1) is selected for the predetermined number, the attachment method is selected based on the same value without considering the circumstances for each substrate K. For example, it is not necessary to provide a different reference value for each model of the gaming machine 1 in consideration of the circumstances for each type of the gaming machine 1, so that it is possible to suppress an increase in man-hours required for determining the mounting method.
Further, for example, when it is desired to employ screwing for the board K having at least one connector terminal 27, it can be realized by setting F = 1.

  When (E-2) is selected for the predetermined number, the connector K is appropriately screwed and latched (or hooked) for the board K having the connector terminal 27 to reduce the mounting man-hour. The board K, which is likely to be loosened due to the insertion / extraction, is screwed and firmly attached.

It is also conceivable that the number obtained by multiplying the number of average connector terminals 27 of the board K by a coefficient is set to a predetermined number. According to this, by setting the coefficient higher, it is possible to reduce the man-hours required for mounting the substrate K by reducing the number of screwing points and increasing the number of latching and hooking points.
On the other hand, by setting the coefficient low, it is possible to increase the number of screwing points and suppress the play of the substrate K and the occurrence of wear.

The main control board K1 and the effect control board K2 are important boards in the gaming machine 1, and the connector terminals 27 tend to increase. Therefore, at least one of the main control board K1 and the effect control board K2 is desired to be attached by screwing.
Such a case can be realized by selecting (E-3) as the predetermined number. For example, when the board K17 is the main control board K1 and the board K18 is the effect control board K2, the main control board K1 as the board K17 is attached to the gaming machine 1 by screwing, and the effect control as the board K18 is performed. The board K2 is attached to the gaming machine 1 by latching or hooking.
Therefore, when one of the main control board K1 and the production control board K2 is firmly attached by screwing, the occurrence of wear and backlash is suppressed, and the other is attached by latching or hooking. Man-hours for work are reduced.
Then, as with the main control board K1 and the effect control board K2, for the board K provided with many connector terminals 27, screwing is easily selected as the attachment method.

Further, when both the main control board K1 and the production control board K2 are firmly attached by screwing, it can be realized by selecting (E-4) as the predetermined number.
As a result, the main control board K1 and the production control board K2 and the board K provided with many connector terminals 27 are attached to the gaming machine 1 by screwing, and wear of the latching portion of the board K when the connector is inserted and removed. And damage is less likely to occur. For the board K with a small number of connector terminals 27, latching and hooking are employed, and the number of mounting steps can be reduced.

In the above example, the substrate K is the selection target of the attachment method to the gaming machine 1. That is, not only the substrate unit 4 accommodated in the substrate case 3 but also the electronic circuit substrate 2 not accommodated in the substrate case 3 was selected as an attachment method.
However, when the substrate unit 4 is damaged, there is a high possibility that the substrate case 3 may be damaged. On the other hand, when the electronic circuit board 2 not stored in the substrate case 3 is worn or damaged. In such a case, the electronic circuit board 2 itself may be worn out or damaged, and may not operate normally. That is, there is a circumstance that the electronic circuit board 2 that is not housed in the board case 3 is at a high risk of being worn or damaged, and is therefore desired to be avoided as much as possible.

  Therefore, the electronic circuit board 2 that is not housed in the board case 3 is attached to the gaming machine 1 by screwing regardless of the number of connector terminals 27, and the electronic circuit board 2 is attached to the board case 3. The above determination may be performed when the substrate unit 4 in the accommodated state is attached.

For example, when (E-2) is adopted as the predetermined number, “the number of average connector terminals 27 included in the substrate K” may be set as “the number of average connector terminals 27 included in the substrate unit 4”.
Thereby, the predetermined number is appropriately set only for the board unit 4 that selects the attachment method to the gaming machine 1, and the possibility that an appropriate attachment method is selected can be increased.

In addition, an attachment method to the gaming machine 1 may be selected in consideration of conditions other than the number of connector terminals 27.
For example, the board K with a large number of connector insertions / removals is attached to the gaming machine 1 by screwing even if the number of connector terminals 27 is small, and the board K with a small number of connector terminals 27 is latched even if the number of connector terminals 27 is large. It can be considered to be attached to the gaming machine 1 by stopping or hooking.
As a result, it is possible to increase the possibility of selecting an appropriate attachment method in consideration of the ease of occurrence of wear or breakage of the locking portion for each substrate K.
Specifically, a value obtained by evaluating the average number of insertions / removals for each connector terminal 27 is given, and the evaluation values of all the connector terminals 27 provided on the board K are added, thereby obtaining the evaluation value of the board K. calculate. Then, as the evaluation value for the substrate K is higher, screwing is adopted as a method of attaching to the gaming machine 1.

In addition to the number of connector terminals 27, the attachment method may be selected in consideration of the position on the board on which the connector terminals 27 are provided.
For example, when the connector terminal 27 provided on the board K is biased to one side of the board K, the burden applied when the connector is inserted or removed may be concentrated on one locking portion. In such a case, every time the connector is inserted / removed, wear of one locking portion is promoted, or only one locking portion may be destroyed.
Therefore, for the board K in which the connector terminals 27 are concentrated on one side (or two sides), the screwing can be easily adopted by multiplying the predetermined number as the determination reference value by a coefficient less than 1. it can.

  Thereby, not only the number of the connector terminals 27 but also the influence at the time of actual insertion / extraction with respect to the locking portion of the board K can be taken into consideration, and the attachment method to the gaming machine 1 can be appropriately selected.

Further, in addition to the number of connector terminals 27, the attachment method may be selected in consideration of the number of button parts, volume parts, etc. provided on the board K.
Specifically, a second type electronic component 5b (a variable resistor or a button component used for a volume or the like) that may be operated by a person for adjustment or maintenance of the gaming machine 1 and the electronic circuit board 2 are provided. A total of the number of third-type electronic components 5c (connector terminals 27 etc.) touched by a person when attached to the gaming machine 1 is evaluated for the substrate K, and the evaluation value is high (ie, the number of electronic components is large) As for K, screwing may be employed as an attachment method to the gaming machine 1.

Thus, it is determined whether or not wear is likely to occur in the locking portion of the board K in consideration of not only the insertion / extraction of the connector but also the pressing of the button component and the operation of the volume component, and an appropriate mounting method is determined based on the determination. Since the selection can be made, it is possible to effectively prevent the occurrence of defects such as rattling of the substrate K and generation of noise.
Of course, the attachment method may be selected in consideration of the number of operations for each electronic component (connector insertion / extraction frequency, button press frequency, etc.).

In addition, although the example which employ | adopts a screw stop as the attachment method to the game machine 1 was demonstrated about the board | substrate K with many connector terminals 27 above, you may employ | adopt a latch stop and a hook stop.
For example, an example will be described in which latching or hooking is used for the board K having many connector terminals 27 and screwing is used for the board K having few connector terminals 27.

Specifically, the board K having a small number of connector terminals 27 tends to take a space for forming the screw insertion hole 6 for the screw 300.
On the other hand, for the board K having many connector terminals 27, there is a tendency that a space for forming the screw insertion hole 6 for the screw 300 tends to be difficult, and in addition, the board K is made large in order to form the screw insertion hole 6. May need to be And when performing the operation | work which removes the board | substrate K from the game machine 1 in the state in which many connectors were inserted in the board | substrate K, it is necessary to insert tools, such as a driver, into the screw head of the screw | thread 300. It becomes difficult to work because it is blocked.

Therefore, for such a board K having many connector terminals 27, there is a possibility that the work man-hours can be remarkably improved by adopting latching or hooking.
Such a mounting method is selected for the board K on which many connector terminals 27 are provided, and the board K is likely to be removed while the frequency of connector insertion / extraction is low. It is desirable to apply.

As described above, a plurality of board units 4 in a state in which the electronic circuit board 2 is housed in the board case 3 are attached to the gaming machine 1. The plurality of board units 4 include a first board unit including a predetermined number or more of connector terminals 27 and a second board unit including a predetermined number of connector terminals 27. As the predetermined number, for example, any one of the above (E-1) to (E-4) may be selected.
The first substrate unit uses first fixing means such as a screwing mechanism as fixing means, and the second substrate unit differs from the first fixing means as first fixing means such as a latching mechanism and a hooking mechanism. Two fixing means are used.
The first fixing means requires a tool such as a driver for releasing the fixation, and the second fixing means does not require a tool for releasing the fixation.
With such a configuration, screwing is easily adopted for the board K having many connector terminals 27, and latching or hooking is easily adopted for the board K having few connector terminals 27.
Accordingly, it is possible to suppress the frequency of occurrence of problems such as wear or damage of the attachment portion when the connector is inserted or removed. Further, by adopting latching or hooking for the board K having a small number of connector terminals 27, the number of work steps can be reduced and the work efficiency can be improved.

In addition, the gaming machine 1 includes a main control board K1 as the main control means and an effect control board K2 as the sub control means as the board unit 4, and communication means capable of unilateral communication from the main control means to the sub control means. One of the main control means and the sub control means may be a first substrate unit, and the other may be a second substrate unit.
Thereby, possibility that an appropriate attachment method will be selected with respect to the main control board K1 and the production | presentation control board K2 which are the board | substrates K important for the game machine 1 can be raised.

Further, the main control board K1 as the main control means provided in the gaming machine 1 is the first board unit, the effect control board K2 as the sub control means is the second board unit, and the first board unit is screwed. The second fixing unit may be fixed to the gaming machine 1 by using, for example, a latching mechanism or a hooking mechanism without using the first fixing unit.
Thereby, the main control board K1 which is the more important board K among the main control board K1 and the effect control board K2 is attached to the gaming machine 1 by screwing. Therefore, it is possible to prevent the main control board K1 from being worn or damaged due to vibration or shaking.

The predetermined number may be an average of the connector terminals 27 included in the board unit 4 attached to the gaming machine 1. That is, (E-2) may be adopted as the predetermined number.
Thereby, screwing and latching (or hooking) are appropriately employed. Therefore, while reducing the number of mounting steps, the board K that is likely to be loosened by inserting and removing the connector is screwed and firmly attached to the gaming machine 1.

[4-6. Sixth Embodiment]
Some of the boards K attached to the gaming machine 1 may be attached at a position close to the player, and some may be attached at a far position.
For example, as shown in FIG. 32, in the ball game machine 100 as the gaming machine 1, the board K <b> 19 attached to the front (player side) from the game board 103 and the back (back side) from the game board 103. It has a substrate K20 to be attached.

In front of the game board 103, there is provided a game area 103a in which a game ball launched by a player falls while colliding with a nail 149, a windmill 147, or the like. The game ball hits not only the nail 149 and the windmill 147 but also the front surface of the game board 103 when falling.
The board K19 located in front of the game board 103 is more likely to receive impact and vibration when the game ball collides with each place than the board K20 located in the rear.

  Therefore, in the present embodiment, an example will be described in which the attachment method is selected in consideration of whether the board K is located in front of or behind the game board 103.

For example, the board K19 that is located in front of the game board 103 (player side) and is close to the location where the game ball collides is attached by screwing when it is attached to the gaming machine 1.
On the other hand, the board K20 which is located behind (on the back side of) the game board 103 and is far from the location where the game ball collides is attached by latching or hooking when being attached to the gaming machine 1.

  By selecting the mounting method in this way, it is possible to suppress the occurrence of defects (worn or damaged in the locking portion) of the substrate K due to various vibrations that occur during the gaming machine 1, and the influence of vibration is small. For the substrate K20 attached to the position, the number of attachment steps can be reduced by latching or hooking.

In addition, the production buttons 111 and 112 in the bullet ball game machine 100 may be strongly hit by the player.
The board K arranged in the vicinity of these effect buttons 111 and 112 is often arranged in front of the game board 103. In other words, such a substrate K is not only affected by impact and vibration caused by the collision of the game balls, but also affected by impact and vibration caused by operations on the effect buttons 111 and 112.

Therefore, it is desirable that such a substrate K is screwed.
Thereby, the abrasion and damage of the board | substrate K based on various impacts and vibrations can be prevented.

The spinning machine 200 will also be described.
As shown in FIG. 4, the spinning machine 200 is provided with a cross button 224 and an effect button 225 in front of the display window 208 and between the max insertion button 216 and the medal insertion port 212.
The max insertion button 216, the cross button 224, and the effect button 225 in the spinning machine 200 may be strongly hit by the player.

Therefore, the board K positioned in front of the symbol rotating unit 203 of the spinning machine 200 is affected not only by the vibration accompanying the rotation of the symbol rotating unit 203 but also by the impact and vibration based on the operation of the above various operators. .
Therefore, a part of the board K positioned in front of the symbol rotating unit 203 (for example, in front of the center of the symbol rotating unit 203) is attached to the rotating game machine 200 by screwing.
Thereby, the abrasion and damage of the board | substrate K based on various impacts and vibrations can be prevented.

Note that the glass door 105 and the front frame 102 of the ball and ball game machine 100 and the front panel 202 of the spinning cylinder game machine 200 may be opened forward during maintenance or when a malfunction occurs during the game.
The substrate K attached to the glass door 105 and the front frame 102 of the ball game machine 100 and the substrate K attached to the front panel 202 of the spinning cylinder game machine 200 are subjected to vibrations and shocks each time each part is opened and closed. Will be transmitted.

Therefore, such a substrate K is subjected to impacts and vibrations caused by a collision of a game ball, vibrations caused by the symbol rotating unit 203, impacts and vibrations caused by operations on various operators, and impacts and vibrations caused by opening / closing of frames and doors. It becomes.
Therefore, it is desirable that such a substrate K be attached to the gaming machine 1 by screwing.
Thereby, generation | occurrence | production of the malfunction based on various impacts and vibrations can be prevented.

As described above, the gaming machine 1 includes the gaming board 103 having the gaming area 103 a and the board unit 4 in a state where the electronic circuit board 2 is housed in the board case 3. The board unit 4 includes a first board unit (board K19) attached at a position on the player side with respect to the game board 103, and a second board unit (board K20) attached at a position on the back side with respect to the game board. Is included.
The first substrate unit uses first fixing means such as a screwing mechanism as fixing means, and the second substrate unit differs from the first fixing means as first fixing means such as a latching mechanism and a hooking mechanism. Two fixing means are used.
The first fixing means requires a tool such as a driver for releasing the fixing, and the second fixing means does not require a tool for releasing the fixing.
As a result, it is possible to suppress the occurrence of defects (abrasion or breakage of the locking portion) of the substrate K caused by the vibration caused by the game ball colliding with each part during the game machine 1 and the influence of the vibration. With respect to the board K20 attached to a position with a small amount, the number of mounting steps can be reduced by latching or hooking.

<5. Modification>

In the various examples described above, it has been described that either the latching or the hooking may be used when the screwing is not used as the mounting method when the board K is attached to the gaming machine 1. In some cases, latching is preferable to hooking, and conversely, hooking is preferable to latching.
Here, such an example will be described.

  Compared with the hook stopper, the latch stopper is often easier to attach and detach the substrate K. As shown in FIGS. 11A and 11B, it is possible to switch between a restricted state and a non-restricted state by sliding the movable portion 16.

On the other hand, as shown in FIG. 14A and FIG. 14B, the hook stopper elastically deforms the column portion 17a of the hook 17 outward to move the engaging portion 17b away from the substrate K on which it is disposed, thereby The attached state can be released.
However, since there is a possibility that the pillar portion 17a is broken when the pillar portion 17a of the hook 17 is elastically deformed, it may not be preferable to attach and remove the substrate K many times.
Further, in order to prevent the pillar portion 17a from being broken, it is conceivable to form the pillar portion 17a with a soft member. However, in this state, in the state where the substrate K is attached to the gaming machine 1, This is not preferable because it may cause sticking.

  Therefore, it is conceivable to adopt latching for the substrate K that is likely to be in a state where the substrate K must be attached or detached.

In addition, as shown in FIGS. 11A and 11B, the latching mechanism is likely to increase in size. Therefore, when there is a possibility that sufficient space for arranging the latching mechanism may not be taken, it is necessary to change the design.
On the other hand, as shown in FIG. 14A and FIG.
Therefore, when the space for providing various mechanisms for attaching the substrate K is narrow, it is conceivable to employ a hook stopper. Thereby, since it is not necessary to make a design change, man-hours and costs can be reduced. Moreover, since the space for arranging the hooking mechanism can be small, the degree of freedom of arrangement of each component such as the substrate K can be increased.

The various embodiments described above can apply a plurality of embodiments simultaneously.
An example is shown below.
In the first embodiment, the example in which the attachment method is selected according to the height of the attachment position of the substrate K has been described. In the fourth embodiment, the example in which the attachment method is selected according to the weight of the substrate K has been described.
Therefore, an example in which the attachment method is selected in consideration of both the height of the attachment position of the substrate K and the weight of the substrate K will be described here.

For example, even if the mounting position of the board K is high, if the weight is light, the board K is less likely to be worn or damaged due to vibrations caused by shaking of the gaming machine 1, and therefore screw fixing is not necessarily employed. Also good.
On the contrary, even if the mounting position of the board K is low, if the weight is heavy, the board K may be worn or damaged due to vibrations caused by shaking of the gaming machine 1, etc. It may be better to do.

Specifically, it is conceivable that a first score is assigned to each board K attached to the gaming machine 1 based on various indices.
For example, with respect to one substrate K, a first score corresponding to the height of the attachment position is given from 0 to 100. The numerical value is increased as the mounting position of the substrate K is higher. That is, the higher the first score, the easier it is to employ screwing as the attachment method.
Next, according to the weight of the board | substrate K, a 2nd score is provided with 0-100. At this time, the numerical value is increased as the substrate K is heavier.

Then, the first score corresponding to the height of the attachment position and the second score corresponding to the weight are added. That is, the total score given to one substrate K is 0 to 200.
Here, with respect to the substrate K having an overall score of 120 or more, screwing is adopted as the attachment method, and with respect to the substrate K having an overall score of less than 120, latching or hooking is adopted as the attachment method.

  In this way, it is possible to select an attachment method that takes into account both the height and weight of the attachment position of the substrate K.

Other examples are also described.
In the fifth embodiment, the example in which the attachment method is selected according to the number of connector terminals 27 provided on the substrate K has been described.
In this example, an example will be described in which the attachment method of the substrate K is selected in consideration of both the first embodiment and the fifth embodiment.

For example, the 1st score according to the height of an attachment position is provided with 0-100 for every board | substrate K. FIG. The numerical value is increased as the mounting position of the substrate K is higher. That is, the higher the first score, the easier it is to employ screwing as the attachment method.
Next, according to the number of connector terminals 27 provided on the substrate K, a second score is given by 0 to 100. At this time, the numerical value is increased as the number of the connector terminals 27 increases.

Then, the first score corresponding to the height of the attachment position and the second score corresponding to the number of connector terminals 27 are added. That is, the total score given to one substrate K is 0 to 200.
Here, with respect to the substrate K having an overall score of 120 or more, screwing is adopted as the attachment method, and with respect to the substrate K having an overall score of less than 120, latching or hooking is adopted as the attachment method.

  This makes it possible to select an attachment method that takes into account both the height of the attachment position of the substrate K and the number of connector terminals 27.

In addition, you may select the attachment method which considered three or more parameters | indexes.
For example, in addition to the first score and the second score described above, a third score or the like may be assigned to each substrate K, and the attachment method may be selected according to the value of the total score obtained by adding those scores.

In addition, the importance for each index may be considered.
For example, when the first score is given according to the height of the mounting position of the substrate K and the second score is given according to the weight of the substrate K, the first score is given if the height of the mounting position is more important. The total score may be calculated after multiplying by 1.5. In this case, the total score is 0 to 250.
Thereby, a total score is given to the substrate K according to the importance for each index. Then, by selecting the method of mounting the substrate K according to the total score calculated in this way, it is possible to effectively solve the problem (wearing portion of the mounting portion is worn or damaged, or noise is generated, and man-hours and costs increase). Can be suppressed.

Examples of arrangement modes of various electronic circuit boards 2 and board cases 3 will be described with reference to FIG.

The cover body 31 is formed of a transparent or translucent resin, and includes two rotation shafts 32 that serve as rotation fulcrums when attached to one side, and a plurality of stoppers 33 for fixing to the gaming machine 1. I have.
The cover body 31 can be opened and closed on the back side of the gaming machine by inserting a rotating shaft 32 through a shaft support (not shown) provided on the back side of the gaming machine 1. Further, in the closed state, the fixing pin attached to the stop portion 33 is engaged with a fixing mechanism (not shown) on the back side of the gaming machine to be fixed to the back side of the gaming machine 1 in a state as shown in FIG.
The cover body 31 is formed with a hole 34 for heat dissipation or the like at a required location.

In the example of FIG. 33, the cover body 31 is not disposed so as to cover all the substrate cases 3, and some of the substrate cases 3 are partially exposed from the cover body 31. Yes.
Of course, the cover body 31 may be disposed so as to cover the entire substrate case 3 on the back surface. What part the cover body 31 covers should just be set suitably according to a model, board | substrate arrangement | positioning, etc.

FIG. 34 shows another example. In FIG. 34, the harness 28 and the cover body 31 for electrically connecting the electronic circuit board 2 are omitted.
On the back side of the gaming machine 1, the electronic circuit board 2 is attached by hooking when it is not housed in the board case 3, or is attached by screwing or latching while being housed in the board case 3. An electronic circuit board 2 is disposed. Note that illustrations of screw and latch fixing portions are omitted.
Further, the substrate K shown in the drawing is a state in which the substrate unit 4 which is the electronic circuit substrate 2 accommodated in the substrate case 3 is overlaid (that is, another substrate unit 4 is arranged on the back side in the gaming machine 1). ).
When a plurality of electronic circuit boards 2 and board cases 3 are arranged in this way, each electronic circuit board is taken into consideration (for example, based on the results obtained by calculating various indices) in consideration of the respective arrangement modes. It is preferable to select a method of attaching 2 or the substrate case 3.
