Description

  The present invention relates to a push button unit body that includes a push button member for a gaming machine that is pressed by a player and that can prevent a substrate disposed inside the push button member from being destroyed by static electricity.

  In an operation button or the like provided in an electronic device, for example, as disclosed in Patent Document 1, a configuration having a key top of an operation switch and a contact portion that is electrically connected when the key top is depressed. Is already known. Furthermore, in such a configuration, a conduction surface is provided in the vicinity of the key top so that static electricity generated in the key top or the like can be released to the exterior case satisfactorily.

  As for gaming machines such as slot machines, for example, as disclosed in Patent Document 2, a unitized operation button device is already known. In such a configuration, a shield plate made of a conductive material is sandwiched between the operation button unit and the cover member to prevent unauthorized operation using an electron gun or the like, and the shield plate is grounded. ing.

  Further, for example, Patent Document 3 discloses a gaming machine having a knob portion of a start lever operated by a player and having an aluminum tape attached to remove static electricity from the knob portion.

JP 2000-323295 A JP 2009-172216 A JP 2008-188281 A

  However, since the entire configuration of the operation switch structure is not unitized in the configuration disclosed in Patent Document 1, a work process for attaching the operation switch to the main body and a work process for applying a structure for preventing static electricity are separately required. It becomes. For example, as an example of a work process for countermeasures against static electricity, a very complicated configuration is disclosed in which a part of a metal case around a key top is scraped to expose a conductive surface.

  Further, the operation button device disclosed in Patent Document 2 has a problem that the shield plate itself connected to the ground is incorporated in the operation button device, and the operation button device is enlarged as a whole.

  Further, the configuration disclosed in Patent Document 3 is such that the aluminum tape is arranged on the housing side and the lever structure is not unitized. Therefore, the work process for attaching the knob portion etc. to the main body, and the aluminum tape on the housing side The work process to be attached to the sheet is required separately, and the structure becomes complicated.

  Accordingly, an object of the present invention is to provide a push button unit body that has already been subjected to static electricity countermeasures against electrical unauthorized operation or malfunction due to static electricity, is compact, and can be easily attached to a gaming machine body. And

  The present invention is a push button unit body that is mounted on a gaming machine body and includes a push button member that is pressed by a player, and is a push button housing space that is fixed to the gaming machine body and opened to the player side. A base body, a push button member disposed in the push button accommodating space of the base body, and a substrate mounted on the base body and mounted with electronic components, the push button member comprising A plunger body having a substrate housing space that advances and retreats with respect to the base body along the pressing direction of the push button member and is open to the player side, and the plunger body so as to shield the substrate housing space A cover body to be mounted, wherein the substrate is disposed in the substrate housing space in a state of being fixed to the base body, and surrounds the push button member. In the push button unit body, a conductive portion for protecting a substrate having conductivity is disposed at a position facing at least a part of a boundary portion between the plunger body and the cover body. is there.

  In such a configuration, since the substrate is disposed in the plunger body, the thickness of the entire push button unit body can be reduced, and as a result, the structure is made compact. In addition, since it is a unitized structure, the attachment work to the gaming machine body is simple.

In the above-described configuration, since the board is arranged in the plunger body, the distance between the surface of the push button member touched by the player and the board is reduced. For this reason, for example, when a player who has accumulated static electricity touches the surface of the push button member and the static electricity flows through the surface of the push button member, the static electricity is likely to face the substrate in the plunger body through the boundary portion. However, according to the present invention, since the substrate protection conductive portion is disposed at a position facing the boundary portion, it is possible to attract the static electricity to the substrate protection conductive portion before entering the plunger body.
As described above, the push button unit body according to the present invention has a unit structure in which countermeasures against static electricity have already been taken, and both the work for mounting on the gaming machine body and the work for countermeasures against static electricity are simplified.

By the way, as a countermeasure against static electricity of the push button member, a measure such as a direct ground connection to the push button member itself is usually considered. However, the push button member is a movable member that moves forward and backward with respect to the base body when pressed, and the configuration in which such a movable member is always connected to the ground makes the ground connection even if the movable member moves forward and backward. For example, it is necessary to consider the wiring so that it does not interfere with other members, and it is necessary to arrange the wiring so that no load is applied to the wiring even if the movable member moves back and forth. The structure becomes complicated. In some cases, the push button member repeatedly advances and retreats, so that the portion connected to the ground connection is fatigued, cracks and the like are generated, and there is a possibility that the countermeasure against static electricity cannot be maintained for a long time.
However, in the present invention, the conductive portion for protecting the substrate is disposed on the side wall portion of the base body, and the conductive portion for protecting the substrate and the push button member are not interlocked, so the structure is not complicated and the design is simple. The above-described problems such as cracks do not occur.

Moreover, since the conductive part for protecting the substrate is hidden from the player side and cannot be seen, it is excellent in aesthetics.
The conductive portion for protecting the substrate may be opposed to the boundary portion only when the push button member is pressed, or may be opposed to the boundary portion only when the push button member is not pressed, Of course, it may be opposed to the boundary portion at any position of the push button member regardless of whether or not it is pressed.

  Further, as a specific configuration of the push button unit body according to the present invention, a decorative member visible from the player side is disposed between the substrate and the cover body, and the surface of the decorative member is made conductive. And at least a part of the boundary part facing the conductive part for substrate protection and a part of the decorative member are opposed to each other, and a part of the boundary part not opposed to the conductive part for substrate protection A configuration in which the other part of the decorative member is opposed is proposed.

In such a configuration, the decorative member that attracts the player's interest can be compactly arranged in the push button member, so that the design of the gaming machine can be improved.
In addition, even if static electricity is charged around the boundary portion that does not face the conductive portion for protecting the substrate, it is possible to appropriately attract the static electricity to the conductive portion for protecting the substrate through the decorative member. .

  An embodiment in which the present invention is applied to a slot machine as a gaming machine will be described according to the following examples.

[Example 1]
A push button unit body 10A according to the first embodiment will be described with reference to FIGS.
As shown in FIG. 1, the push button unit body 10A is attached to the gaming machine main body 1 of the slot machine.

  As shown in FIGS. 1 and 3, the push button unit body 10 </ b> A includes a base body 20 having a box shape having a push button accommodation space X opened to the player side. A push button member 30, which is an effect button that is pressed by the player, is disposed in the push button accommodating space X of the base body 20.

  The base body 20 includes a side wall portion 21 that surrounds the push button accommodating space X, and a pair of fixing protrusions 23 provided with fixing holes 22 are provided on the outer surface thereof. Note that a metal bolt (not shown) as a fixing means can be inserted into the fixing hole 22, whereby the base body 20 is fixed to the gaming machine main body 1.

  A screw base 24 is formed on the bottom of the base body 20 so as to protrude toward the push button accommodating space X. And the board | substrate 40 with which electronic components, such as the light transmission type sensor 42 and the LED element 43, were mounted is attached to the screw stand 24 via the screw 41 (refer FIG. 1). The board 40 includes a connection terminal 44 that is electrically connected to a main board (not shown) attached to the gaming machine main body 1.

  On the other hand, the push button member 30 includes a plunger body 31 having a board housing space Y opened to the player side, and a transparent cover body attached to the plunger body 31 so as to shield the board housing space Y. 35.

  The plunger body 31 has a structure capable of moving forward and backward with respect to the base body 20 along the pressing direction M of the push button member 30. Specifically, as shown in FIG. 1, a coil spring 38 is disposed between the plunger body 31 and the base body 20, and the coil spring 38 moves the plunger body 31 from the base body 20 side to the player. It is energizing towards the side.

  As shown in FIGS. 1 and 3, the light path of the light transmission type sensor 42 mounted on the substrate 40 is shielded at a position located in the inner space of the coil spring 38 at the bottom of the plunger body 31. A light shielding plate 32 is formed so as to protrude toward the gaming machine main body 1 side.

  Further, the substrate 40 fixed to the base body 20 is disposed in the substrate housing space Y of the plunger body 31.

  As shown in FIG. 1, a boundary portion 37 between the plunger body 31 and the cover body 35 is formed by a portion where the peripheral edge portion of the plunger body 31 and the peripheral edge portion of the cover body 35 abut each other.

  Furthermore, as shown in FIGS. 1 to 3, a plate-shaped decorative member 50 that is visible from the player side and has a conductive surface is disposed between the plunger body 31 and the cover body 35. . The outer dimension of the decorative member 50 is set to a dimension slightly smaller than the inner dimension of the cover body 35, and the entire peripheral edge portion of the decorative member 50 faces the entire periphery of the boundary portion 37.

  Further, as shown in FIG. 1, gaps d are formed between the side wall portion 21 and the plunger body 31 of the base body 20 and between the side wall portion 21 and the cover body 35, respectively. Even when a pressing operation is performed to advance and retract 30, the arrangement does not interfere with each other.

  Note that the base body 20, the plunger body 31, and the cover body 35 are formed of a non-conductive resin material.

  In the above-described configuration, when the push button member 30 is not pressed, the operation surface 36 that is the surface of the cover body 35 is slightly protruded from the surface of the gaming machine body 1 to the player side. The light path of the light transmission type sensor 42 is blocked by the light blocking plate 32 of the plunger body 31.

Next, the operation mode of the push button member 30 will be described.
When the player presses the operation surface 36 of the cover body 35 of the push button member 30, the plunger body 31 is pushed into the base body 20 and the light shielding plate 32 is detached from the optical path of the light transmission type sensor 42.

  Then, the light transmission type sensor 42 detects this, and transmits an electric signal indicating that the push button member 30 has been pressed to the main body substrate.

Next, the main part of the present invention is described.
An electrically conductive substrate protecting conductive portion 60 is formed at a position facing at least a part of the boundary portion 37 of the push button member 30 in the side wall portion 21 of the base body 20 surrounding the push button member 30. . Specifically, a flat plate-like side plate portion 61 constituting a part of the substrate protecting conductive portion 60 is disposed on the side wall portion 21 of the base body 20. The dimensional shape of the side plate portion 61 is set so as to always face the boundary portion 37 regardless of the pressing operation of the push button member 30.

  The side plate portion 61 is disposed only at the position of the side wall portion 21 located on the left side in FIG. 1, and hereinafter, the portion of the boundary portion 37 facing the side plate portion 61 is defined as the conductive portion side boundary portion 37a (FIG. 2, FIG. 4), and a portion of the boundary portion 37 that does not face the side plate portion 61 will be described as a non-conductive portion side boundary portion 37b (see FIGS. 2 and 4).

  Further, the side plate portion 61 is formed with a continuous conductive protrusion 62 that covers one side surface of the fixing protrusion 23 provided on the base body 20. In the protrusion 62, a hole 63 through which a bolt (not shown) can be inserted is provided at a position corresponding to the fixing hole 22 provided in the fixing protrusion 23.

  In this configuration, when a metal bolt is inserted into the fixing hole 22 provided in the fixing protrusion 23 of the base body 20, the entire push button unit body 10A is attached to the gaming machine body 1 as described above. The board protecting conductive portion 60 is fixed and grounded via a bolt.

Here, as shown in FIG. 4A, static electricity is generated, for example, on the side of the operation surface 36 of the cover body 35 close to the board protection conductive portion 60 in a state where the push button member 30 is not pressed. In this case, the static electricity flows through the side surface of the cover body 35 as indicated by the arrow A, and is attracted to the side plate portion 61 of the board protecting conductive portion 60. Therefore, it is possible to prevent the substrate 40 from being electrically destroyed due to the generation of static electricity.
Here, the flow of static electricity in the push button unit body 10A is determined based on the creepage distance and the spatial distance in the so-called push button unit body 10A. Specifically, when there are two points with different directions relative to the position where the static electricity is generated, the static electricity is directed toward the point where the electrical distance is short, based on the position where the static electricity is generated. Flowing. At this time, when the creepage distance or the spatial distance is increased, the electrical distance is increased accordingly. However, when there is a conductive member such as metal on the path through which static electricity flows, the conductive member is practically used. Are excluded from the electrical distance.

  Here, in FIG. 4A, if the substrate protecting conductive portion 60 is not formed, the static electricity flows through the side surface and the boundary portion 37 of the cover body 35 as shown by the arrow B, and the arrow As shown to C, it will flow toward the board | substrate 40 through the decoration member 50 which has electroconductivity.

In other words, if the board protecting conductive portion 60 is not provided, the static electricity generated on the operation surface 36 tends to flow along the path via the boundary portion 37 as indicated by arrows B and C.
However, in the push button unit body 10 </ b> A, the side plate portion 61 of the board protecting conductive portion 60 is disposed at a position facing the boundary portion 37. The electrical distance between the operation surface 36 and the side plate portion 61 of the substrate protection conductive portion 60 (the shortest creepage distance between the operation surface 36 and the side plate portion 61 of the substrate protection conductive portion 60) is the operation surface 36 and the substrate. 40 (the total distance of the shortest creepage distance between the operation surface 36 and the decorative member 50 and the shortest spatial distance between the decorative member 50 and the substrate 40).
For this reason, the static electricity that has reached the vicinity of the boundary portion 37 is attracted to the side plate portion 61 of the substrate protection conductive portion 60 with a short electrical distance, and thus the static electricity flows toward the substrate 40 through the boundary portion 37. It becomes possible to avoid that.
That is, static electricity passes through the boundary portion 37 by making the electrical distance between the operation surface 36 and the side plate portion 61 of the board protecting conductive portion 60 shorter than the electrical distance between the operation surface 36 and the substrate 40. Thus, it is possible to avoid the flow toward the substrate 40.

  As described above, the push button unit body 10 </ b> A has the board protecting conductive portion 60 disposed at a position outside the push button member 30 and facing the boundary portion 37. The electrical distance between the operation surface 36 and the substrate 40 in the push button member 30 is sufficiently separated from each other. Easy design. Therefore, the design for making the push button unit 10A as compact as possible and the design for countermeasure against static electricity of the substrate 40 can be made compatible with each other.

  Also, as shown in FIG. 4B, when static electricity is generated on the side of the operation surface 36 of the cover body 35 close to the board protecting conductive portion 60 when the push button member 30 is pressed. Such static electricity flows through the side surface of the cover body 35 as indicated by the arrow D, and is attracted to the side plate portion 61 of the conductive portion 60 for substrate protection. Therefore, it is possible to prevent the substrate 40 from being electrically destroyed due to the generation of static electricity.

  Here, if the substrate protection conductive portion 60 is not formed, static electricity flows through the side surface and the boundary portion 37 of the cover body 35 as indicated by an arrow E, and further, as indicated by an arrow F, the decoration is applied. It flows toward the substrate 40 via the member 50.

In other words, as shown by arrows E and F, the static electricity generated on the operation surface 36 tends to flow along a route passing through the boundary portion 37. However, in the push button unit body 10A, the push button member 30 is pressed. The side plate portion 61 of the board protection conductive portion 60 is disposed at a position opposite to the position of the boundary portion 37 in the state where the substrate protection is performed. The electrical distance between the operation surface 36 and the side plate portion 61 of the substrate protection conductive portion 60 (the shortest creepage distance between the operation surface 36 and the side plate portion 61 of the substrate protection conductive portion 60) is the operation surface 36 and the substrate. 40 (the total distance of the shortest creepage distance between the operation surface 36 and the decorative member 50 and the shortest spatial distance between the decorative member 50 and the substrate 40).
For this reason, since the static electricity that has reached the vicinity of the boundary portion 37 is attracted to the side plate portion 61 of the board protection conductive portion 60 with a short electrical distance even when the push button member 30 is being pressed, It is possible to avoid flowing toward the substrate 40 through the boundary portion 37.
That is, even in the state where the push button member 30 is pressed, the electrical distance between the operation surface 36 and the side plate portion 61 of the conductive portion 60 for protecting the substrate is greater than the electrical distance between the operation surface 36 and the substrate 40. By shortening, it becomes possible to avoid that static electricity flows toward the board | substrate 40 through the boundary part 37. FIG.

As shown in FIG. 5A, static electricity is generated, for example, at a position far from the board protecting conductive portion 60 in the operation surface 36 of the cover body 35 in a state where the push button member 30 is not pressed. In this case, the static electricity flows through the side surface of the cover body 35 as indicated by an arrow G, and then enters the push button member 30 via the non-conductive portion side boundary portion 37b, and the surface of the decorative member 50 having conductivity is formed. It flows and is attracted to the side plate portion 61 of the substrate protection conductive portion 60 through the conductive portion side boundary portion 37a as indicated by an arrow H.
In other words, static electricity generated around the non-conductive portion side boundary portion 37b enters the push button member 30 through the non-conductive portion side boundary portion 37b, and has a conductive decorative member 50 as indicated by an arrow Z1. It is conceivable that the air flows toward the substrate 40 via the surface of the plunger body 31 or flows toward the substrate 40 via the surface of the plunger body 31 on the substrate accommodating space Y side as indicated by an arrow Z2.
However, in the push button unit body 10A, the decorative member 50 having a conductive surface is disposed at a position facing the conductive portion side boundary portion 37a and also facing the nonconductive portion side boundary portion 37b. . The electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60 is shorter than the electrical distance between the non-conductive portion side boundary portion 37b and the substrate 40. .
Specifically, the electrical distance between the non-conductive portion side boundary portion 37b and the substrate 40 is such that when static electricity flows through the path indicated by the arrow Z1, the non-conductive portion side boundary portion 37b and the surface of the decorative member 50 are When the static electricity flows through the path indicated by the arrow Z2, the distance between the shortest creepage distance and the shortest spatial distance between the surface of the decorative member 50 and the substrate 40 is the distance on the substrate housing space Y side of the plunger body 31. This is the shortest creepage distance between the non-conductive portion side boundary portion 37b and the substrate 40 via the surface.
On the other hand, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the board protecting conductive portion 60 is excluded from the electrical distance because the surface of the decorative member 50 on the path has conductivity. Therefore, the electrical distance between the non-conductive portion side boundary portion 37b and the substrate 40 can be shortened.
Specifically, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the board protecting conductive portion 60 is such that the non-conductive portion side boundary portion 37b of the decorative member 50 is separated from the non-conductive portion side boundary portion 37b. And the distance from the end portion of the decorative member 50 facing the conductive portion side boundary portion 37a to the side plate portion 61 of the conductive portion 60 for substrate protection through the conductive portion side boundary portion 37a Is the total distance.
Therefore, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60 is the actual distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60. The dimension of the decorative member 50 occupying most of the actual distance is excluded from the distance, and thus becomes shorter.
Thereby, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60 is shorter than the electrical distance between the non-conductive portion side boundary portion 37b and the substrate 40. Thus, the substrate 40 can be arranged.
The electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60 is made shorter than the electrical distance between the non-conductive portion side boundary portion 37b and the substrate 40. When static electricity is charged around the non-conductive portion side boundary portion 37 b that does not face the conductive portion for substrate protection 60, the static electricity can be appropriately attracted to the conductive portion for substrate protection 60 through the decorative member 50.
Therefore, even in such a case, it is possible to prevent the substrate 40 from being electrically destroyed due to the generation of static electricity.

  As described above, the push button unit body 10 </ b> A has the board protecting conductive portion 60 disposed at a position outside the push button member 30 and facing the boundary portion 37. It is easy to design the electrical distance between the conductive portion 60 for protecting the board and the board protecting conductive portion 60 sufficiently while effectively using the decorative member 50 as a conductive path, and it is within the operation surface 36 and the push button member 30. It is easy to design with a sufficient electrical distance from the substrate 40. Therefore, the design for making the push button unit 10A as compact as possible with the decorative member 50 incorporated therein and the design for the countermeasure against static electricity of the substrate 40 can be made compatible with each other.

Further, as shown in FIG. 5B, when the push button member 30 is pressed, for example, static electricity is generated at a position far from the board protecting conductive portion 60 in the operation surface 36 of the cover body 35. Even in such a case, the static electricity flows on the side surface of the cover body 35 as indicated by an arrow J, and then enters the push button member 30 via the non-conductive portion side boundary portion 37b and flows on the surface of the decorative member 50. Then, as shown by an arrow K, the side plate portion 61 of the substrate protecting conductive portion 60 is attracted via the conductive portion side boundary portion 37a.
In other words, static electricity generated around the non-conductive portion side boundary portion 37b enters the push button member 30 through the non-conductive portion side boundary portion 37b, and has a conductive decorative member 50 as indicated by an arrow Z3. It is conceivable that the gas flows toward the substrate 40 through the surface, or flows toward the substrate 40 through the surface of the plunger body 31 on the substrate accommodating space Y side as indicated by an arrow Z4.
However, in the push button unit body 10A, in a state in which the push button member 30 is pressed, the push button unit body 10A has conductivity at a position facing the conductive portion side boundary portion 37a and facing the nonconductive portion side boundary portion 37b. A decorative member 50 having a surface is arranged, and the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60 is the non-conductive portion side boundary portion 37b and the substrate 40. It is shorter than the electrical distance.
Specifically, the electrical distance between the non-conductive portion side boundary portion 37b and the substrate 40 is the shortest distance between the non-conductive portion side boundary portion 37b and the decorative member 50 when static electricity flows along the path indicated by the arrow Z3. When the static electricity flows along the path indicated by the arrow Z4, the creepage distance and the shortest spatial distance between the decorative member 50 and the substrate 40 are combined, and the surface of the plunger body 31 passes through the surface on the substrate accommodation space Y side. This is the shortest creepage distance between the non-conductive portion side boundary portion 37b and the substrate 40.
On the other hand, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the board protecting conductive portion 60 is excluded from the electrical distance because the decorative member 50 on the path has conductivity. The distance between the non-conductive portion side boundary portion 37b and the substrate 40 can be shortened.
Specifically, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the board protecting conductive portion 60 is such that the non-conductive portion side boundary portion 37b of the decorative member 50 is separated from the non-conductive portion side boundary portion 37b. And the distance from the end portion of the decorative member 50 facing the conductive portion side boundary portion 37a to the side plate portion 61 of the conductive portion 60 for substrate protection through the conductive portion side boundary portion 37a Is the total distance.
Therefore, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60 is the actual distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60. The dimension of the decorative member 50 occupying most of the actual distance is excluded from the distance, and thus becomes shorter.
Thereby, even in the state where the push button member 30 is pressed, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the board protecting conductive portion 60 is the same as the non-conductive portion side boundary portion 37b. The electrical distance from the substrate 40 is shorter.
Even in the state in which the push button member 30 is pressed, the electrical distance between the non-conductive portion side boundary portion 37b and the side plate portion 61 of the substrate protecting conductive portion 60 is the non-conductive portion side boundary portion 37b and the substrate. When the static electricity is charged around the non-conductive portion side boundary portion 37 b that is not opposed to the substrate-protecting conductive portion 60 because it is shorter than the electrical distance to 40, the substrate-protecting conductive portion 60 is interposed via the decorative member 50. It is possible to attract static electricity appropriately.
Therefore, even in such a case, it is possible to prevent the substrate 40 from being electrically destroyed due to the generation of static electricity.

The side plate portion 61 of the board protecting conductive portion 60 is disposed on the side wall portion 21 of the base body 20 so as to be separated from the push button member 30, and the substrate protecting conductive portion 60 is pressed by the push button member 30. Since the position does not change regardless of the presence or absence of the operation, the structure of the push button unit 10A is not complicated as a whole, and it is suppressed that the countermeasure against static electricity cannot be maintained due to the occurrence of cracks or the like in the parts. .
In addition, the unit structure has already been provided with countermeasures against static electricity, and both the mounting work to the gaming machine body 1 and the work for countermeasures against static electricity are simplified. In addition, since the board protecting conductive portion 60 is hidden from the player side and cannot be seen, it is excellent in aesthetics.

Furthermore, since the decorative member 50 that attracts the player's interest is compactly arranged in the push button member 30 in the push button unit body 10A, the thickness of the entire push button unit body 10A can be reduced, and The design of the slot machine can be improved.
Further, even when static electricity is charged around the non-conductive portion side boundary portion 37 b that does not face the conductive portion 60 for protecting the substrate, the static electricity is appropriately attracted to the conductive portion 60 for protecting the substrate through the decorative member 50. Can do.

[Example 2]
A push button unit body 10B according to the second embodiment will be described with reference to FIG. Since the push button unit body 10B has the same configuration as the push button unit body 10A of the first embodiment except that the decorative member 50 is not disposed, the same reference numerals are given to those having the same configuration. The description is omitted.

  As shown in FIG. 6A, in the state where the push button member 30 is not pressed, for example, when static electricity is generated on the side of the operation surface 36 of the cover body 35 that is close to the conductive portion 60 for protecting the substrate, this occurs. The static electricity flows through the side surface of the cover body 35 as indicated by an arrow N, and is attracted to the side plate portion 61 of the board protecting conductive portion 60. Therefore, it is possible to prevent the substrate 40 from being electrically destroyed due to the generation of static electricity.

  Here, if the substrate protection conductive portion 60 is not formed, static electricity flows through the side surface of the cover body 35 as indicated by the arrow P, and further, static electricity flows toward the substrate 40 via the boundary portion 37. It will flow.

In other words, the static electricity generated on the operation surface 36 tends to flow along a route passing through the boundary portion 37 as indicated by an arrow P, but in the push button unit body 10B, at a position facing the boundary portion 37, The side plate portion 61 of the substrate protection conductive portion 60 is disposed, and the electrical distance between the operation surface 36 and the side plate portion 61 of the substrate protection conductive portion 60 (the operation plate 36 and the side plate portion of the substrate protection conductive portion 60). 61 is shorter than the electrical distance between the operation surface 36 and the substrate 40 (the shortest creepage distance between the operation surface 36 and the substrate 40).
For this reason, the static electricity that has reached the vicinity of the boundary portion 37 is attracted to the side plate portion 61 of the substrate protection conductive portion 60 with a short electrical distance, and thus the static electricity flows toward the substrate 40 through the boundary portion 37. It becomes possible to avoid that.
That is, static electricity passes through the boundary portion 37 by making the electrical distance between the operation surface 36 and the side plate portion 61 of the board protecting conductive portion 60 shorter than the electrical distance between the operation surface 36 and the substrate 40. Thus, it is possible to avoid the flow toward the substrate 40.

  As described above, the push button unit body 10 </ b> B has the board protecting conductive portion 60 disposed at a position facing the boundary portion 37 outside the push button member 30. The electrical distance between the operation surface 36 and the substrate 40 in the push button member 30 is sufficiently separated from each other. Easy design. Therefore, the design for making the push button unit 10B as compact as possible and the design for countermeasure against static electricity of the substrate 40 can be made compatible with each other.

  Also, as shown in FIG. 6B, when static electricity is generated on the side of the operation surface 36 of the cover body 35 close to the board protection conductive portion 60 when the push button member 30 is pressed. Such static electricity flows through the side surface of the cover body 35 as indicated by an arrow Q, and is attracted to the side plate portion 61 of the board protecting conductive portion 60. Therefore, it is possible to prevent the substrate 40 from being electrically destroyed due to the generation of static electricity.

  Here, if the substrate protection conductive portion 60 is not formed, static electricity flows through the side surface of the cover body 35 as indicated by the arrow R, and further, electricity flows toward the substrate 40 via the boundary portion 37. It will flow.

In other words, the static electricity generated on the operation surface 36 tends to flow along a route passing through the boundary portion 37 as indicated by the arrow R, but the push button member 30 is pressed in the push button unit body 10B. The side plate portion 61 of the substrate protecting conductive portion 60 is disposed at a position opposite to the position of the boundary portion 37 in the state, and the electrical distance (the distance between the operation surface 36 and the side plate portion 61 of the substrate protecting conductive portion 60 ( The shortest creepage distance between the operation surface 36 and the side plate portion 61 of the substrate protecting conductive portion 60 is shorter than the electrical distance between the operation surface 36 and the substrate 40 (the shortest creepage distance between the operation surface 36 and the substrate 40). Therefore, since the static electricity that has reached the vicinity of the boundary portion 37 is attracted to the side plate portion 61 of the board protection conductive portion 60 having a short electrical distance even when the push button member 30 is pressed, the static electricity is bounded by the boundary. Via part 37 It is possible to avoid that may flow towards the plate 40.
That is, even in the state where the push button member 30 is pressed, the electrical distance between the operation surface 36 and the side plate portion 61 of the conductive portion 60 for protecting the substrate is greater than the electrical distance between the operation surface 36 and the substrate 40. By shortening the length, it is possible to prevent static electricity from flowing toward the substrate 40 via the boundary portion 37 even when the push button member 30 is pressed.

  In addition, in the said Example, the shape dimension of each member of pushbutton unit body 10A, 10B can be freely selected suitably.

  Further, for example, the cover body 35 may have a configuration having transparency as a whole, or may have a configuration in which a portion having transparency is partially formed.

  The board protecting conductive portion 60 may face the boundary portion 37 only when the push button member 30 is pressed, or face the boundary portion 37 only when the push button member 30 is not pressed. Also good.

Moreover, the board | substrate protective electroconductive part 60 should just be arrange | positioned in the position which opposes at least one part of the boundary part 37, and may have the location which is not partially opposed.
Moreover, the structure currently formed so that the board | substrate protection electroconductive part 60 may oppose the boundary part 37 over a perimeter may be sufficient.

  Moreover, the decoration member 50 does not need to have electroconductivity only in the surface, and the whole may be formed with the electroconductive material.

  Furthermore, the configuration may be such that the peripheral portion of the decorative member 50 faces the boundary portion 37 over the entire circumference, and a part of the conductive portion side boundary portion 37a that faces the board protecting conductive portion 60 is decorated. A part of the member 50 is opposed, and a part of the non-conductive part side boundary part 37b that is not opposed to the board protecting conductive part 60 is opposed to another part of the decorative member 50. Also good.

  The substrate 40 may have a circuit related to the operation of the push button member 30 or may have a circuit not related to the operation of the push button member 30. Specifically, the circuit related to the operation of the push button member 30 is exemplified by a circuit that detects a pressed state or a non-pressed state of the push button member 30 based on a pressing operation of the push button member 30. Further, as a circuit that is not specifically related to the operation of the push button member 30, a circuit for illuminating the inside of the push button member 30 by the LED element 43 and providing a stunning light emission mode is exemplified.
