Description

  The present invention relates to a gaming machine, and more particularly to a gaming machine in which a control device for electrically controlling various gaming parts is disposed on a mechanism set board provided on the back side of the machine.

  For example, in a pachinko machine or an arrangement ball machine, which is one of the representative examples of gaming machines, various winning holes and guide cars are arranged on the gaming board set in the machine, while a symbol display device, a winning device, lamps, etc. In addition, other electrical components such as a speaker are arranged. Further, a mechanism set board in which a ball passage of various game balls is formed is provided on the back side of the gaming machine, and a control board for controlling each electrical component is provided on the board case as a mechanism set board. The accommodated control device is arranged. Here, as the control device, for example, there are provided various control devices such as a main control device that controls the entire gaming machine, a sub-control device provided corresponding to each electric component, and a power supply control device that performs power supply control. It has been. Then, each control device controls the corresponding electrical component, so that the symbol display game is played on the symbol display device, and in response to the symbol variation game, the lamps are made to emit light or a sound effect is emitted from a speaker. Or play the required game.

By the way, if the control device is disposed on the mechanism set panel as it is, malfunction may occur in the control device due to noise generated from other control devices or the like. It is necessary to do. As a noise countermeasure for such a control device, for example, as disclosed in Patent Document 1, a shield member made of a conductive material is disposed on the back surface of the control device (a surface facing the mechanism set board). In order to prevent noise, the control device is known to prevent malfunction. In addition, the said shield member is attached with respect to the said control apparatus so that attachment or detachment or rotation is possible. That is, in the control device disclosed in Patent Document 1, it is possible to prevent the malfunction of the control device with a simple configuration by simply attaching the shield member, and only to attach or detach or rotate the shield plate as necessary. Thus, the control board inside the control apparatus can be visually observed from the outside so that the abnormality of the control board can be confirmed.
JP-A-11-267323

  Here, the shield member is a member that can be used as it is as long as there is no change in the outer shape of the control device even when it is necessary to replace the control device with a new control device. However, since the shield member is directly attached to the control device, when the control device is replaced, the shield member is also replaced, resulting in an increase in waste and a factor of increasing costs. When the shield member is detachably provided on the control device, the above-described problem does not occur if the shield member is removed and replaced with a new control device. However, in this case, since complicated replacement work is required, work efficiency such as model change is lowered. Further, the shield member removed from the original control device must be stored until it is attached to a new control device, so that it is necessary to secure the storage space, and in some cases, the removed shield member may be lost. There is.

In addition, when changing the model, the outer shape of the control device may be changed. In this case, the size of the shield member attached to the original control device will not match, so the shape of the shield member will also be changed. It is necessary to point out the problem of increasing costs. Further, in the configuration in which the shield member is attached to the control device, the shape of the shield member needs to be formed in accordance with the shape of the control device, and the shape of the shield member is limited. Here, the control device may be handled separately from the gaming machine, and it is preferable to suppress the weight of the control device as much as possible in consideration of convenience such as storage, transportation, and attachment to the gaming machine. . In this case, since there is a limit in reducing the weight of the control device itself, the weight of the shield member is inevitably reduced. Therefore, since the shape of the shield member is consequently limited to a simple flat plate shape and thin and light, there is a portion where the noise blocking effect on the control device is not perfect.
Accordingly, an object of the present invention is to provide a gaming machine that can be used in common without changing the shield member when changing the model.

In order to overcome the above-mentioned problems and achieve the intended purpose, a gaming machine according to the present invention includes:
In a gaming machine in which a control device (20) for various electrical components is detachably arranged on a mechanism set board (30) provided on the back side of the machine,
A shield member (40) for blocking noise from the noise generation source (21) is disposed on the mechanism set panel (30) so as to be positioned between the control device (20) and the noise generation source (21). It is characterized by that.

  In addition, the noise generation source (21) may be a second control device (21) disposed to face the control device (20) in a positional relationship where at least a part thereof overlaps in the front-rear direction.

  Furthermore, the shield member (40) can be attached via an attachment portion (35) in which the control device (20) formed on the mechanism set panel (30) is disposed.

Furthermore, the attachment part (35) is spaced apart from the first engagement part (36) formed to project rearward from the mechanism set board (30) and the first engagement part (36). An opening (38) formed at a position where the first engagement portion (36) is opened,
The control device (20) includes a second engaging portion (24a) that can be engaged with the first engaging portion (36), and a first protruding portion that can be inserted into the opening (38). (25) is provided,
The shield member (40) can be inserted into the third engagement portion (41) engageable with the first engagement portion (36) and the opening portion (38). A second protrusion (42) that is inclined toward the mechanism set panel (30) as it is separated from the engagement portion (41) is provided,
With the second projecting portion (42) inserted into the opening (38), the first engaging portion (36) and the third engaging portion (41) are engaged. The shield member (40) is attached to the attachment portion (35), and the first projecting portion (25) is inserted into the opening (38). The control device (20) may be attached to the attachment portion (35) by engaging the second engagement portion (24a).

The attachment portion (35) is separated from the first engagement portion (36) and the first engagement portion (36) formed to protrude rearward from the mechanism set board (30). A shaft portion (51) formed to project upward at a position,
The control device (20) includes a second engagement portion (24a) that can be engaged with the first engagement portion (36), and a first shaft hole into which the shaft portion (51) can be inserted. (53) is provided,
The shield member (40) has a third engagement portion (41) engageable with the first engagement portion (36) and a second shaft hole into which the shaft portion (51) can be inserted. (55) is provided,
The third engagement portion (41) and the first engagement portion (the first engagement portion (41) of the shield member (40), which is rotatably supported by inserting the shaft portion (51) into the second shaft hole (55). 36), the shield member (40) is attached to the attachment portion (35), and the shaft portion (51) can be inserted into the first shaft hole (53) and rotated. By engaging the second engagement portion (24a) and the first engagement portion (36) of the control device (20) supported by the control device (20), the control device (20) is attached to the attachment portion (35). It can also be configured to be mounted.

  The gaming machine according to claim 1 of the present invention is configured such that the shield member is attached to the mechanism set board, so that only the control device can be replaced when the model is changed or the control device fails or is damaged. That is, since the shield member can be used as it is, waste and cost do not increase when replacing the control device. Further, since it is not necessary to remove the shield member from the control device when replacing or maintaining the control device, the work can be easily performed and the shield member is not lost. And even if it is a case where the external shape of a control apparatus is changed, it is not necessary to change the shape of a shield member, and also in this case, there exists an advantage which can suppress a waste material and cost. Furthermore, since the shield member is attached to the mechanism set panel, the shape and the like of the shield member can be arbitrarily determined without being constrained by the weight, so that noise can be blocked more reliably. The shield member is configured not to be handled integrally with the control device, so that the control device can be stored, transported, attached to a gaming machine, etc. even when the weight of the shield member is increased. There will be no decrease in convenience.

  In addition, according to the gaming machine according to claim 2, when the shield member is located between the control device and the second control device as a noise generation source, the two control devices are arranged in an overlapping manner. However, it is possible to prevent malfunction of the control device due to noise. Similarly, since the noise generated due to the control device is also blocked by the shield member, it is possible to prevent malfunction from occurring in the second control device due to the noise. Furthermore, since the control device and the second control device are arranged one after the other so that there is a space margin in the surface direction of the mechanism set panel, the degree of freedom of installation of other members on the mechanism set panel is increased. Can be improved. Therefore, various members can be arranged on the mechanism set board with a margin, and new members that are not present can be installed.

  According to the gaming machine of the third aspect, since it is not necessary to form the attachment portion corresponding to each of the control device and the shield member, the cost can be reduced and a space can be provided.

  According to the gaming machine of the fourth aspect, the third engaging portion of the shield member is inserted into the opening formed in the mechanism set board in the state where the second protrusion formed on the shield member is inserted into the mechanism. By engaging with the first engaging portion of the set board, the shield member can be attached to the mechanism set board, and the control is performed with the first protrusion formed in the control device inserted into the opening. By engaging the second engagement portion of the device with the first engagement portion, the control device can be attached to the mechanism set board. Thus, since it is not necessary to form the attachment part corresponding to each of a control apparatus and a shield member, while being able to aim at cost reduction, a space margin can also be made. Further, when the control device is mounted with the shield member attached to the mounting portion by tilting the second projection portion of the shield member toward the mechanism set panel side, the first protrusion portion of the control device Can be easily inserted into the opening.

  According to the gaming machine of the fifth aspect, the third engagement portion of the shield member is connected to the mechanism set board in a state where the shaft portion of the attachment portion is inserted into the second shaft hole formed in the shield member. By engaging the first engaging portion, the shield member can be attached to the mechanism set panel, and the control device is inserted in the state where the shaft portion of the attachment portion is inserted into the first shaft hole formed in the control device. By engaging the second engagement portion with the first engagement portion, the control device can be attached to the mechanism set board. Thus, since it is not necessary to form the attachment part corresponding to each of a control apparatus and a shield member, while being able to aim at cost reduction, a space margin can also be made. In addition, since the control device is rotatably supported, it is possible to check the surface facing the shield member of the control device simply by rotating the control device, so that maintenance work and the like can be easily performed. There are advantages. And, since the shield member is configured to be rotatable, even if the member covered with the shield member needs to be replaced or maintained, it is not necessary to remove the shield member. The shield member is not lost during work.

  Next, preferred embodiments 1 and 2 of the gaming machine according to the present invention will be described in detail below with reference to the accompanying drawings. In the first and second embodiments, a general pachinko machine that uses a pachinko ball as a game medium will be described as an example. In the following description, “left” and “right” refer to the pachinko machine 10 as viewed from the back side as shown in FIG.

  First, a schematic configuration of the pachinko machine according to the first embodiment will be described with reference to FIG. In the pachinko machine 10, the inner frame 12 can be attached to and detached from the front side of the opening of the outer frame 11 forming the outer shell by using connection support means and locking means (both not shown) provided in the pachinko machine 10. It is assembled to. A game board (not shown) constituting a required game area is attached to the middle frame 12 so as to be detachable and replaceable, and a front frame 13 having a glass plate on the front side of the middle frame 12 is opened and closed. The game board is transparently protected by being assembled, and an upper ball tray and a lower ball tray (both not shown) capable of storing pachinko balls are disposed below the middle frame 12 and A handle unit 18 is provided for firing a pachinko ball stored in the upper ball tray toward the game board in accordance with the player's operation. Further, on the back side of the middle frame 12, a main control device (control device) 20 that controls the entire pachinko machine 10, and a power supply control device (second control device) that controls the power supplied to various electrical components and the like. 21 and a mechanism set panel 30 to which various control devices such as a payout control device 27 are attached. That is, in the pachinko machine 10 according to the first embodiment, a player operates the handle unit 18 to fire a pachinko ball in the upper ball dish, so that a required game is performed based on the control of the main controller 20. It is supposed to be.

  Here, the various control devices 20, 21, 27 arranged in the pachinko machine 10 are configured by accommodating a control board (not shown) in a protective case 22 made of transparent resin, and from the outside of the protective case 22. The control board can be visually recognized. The control board accommodated in the protective case 22 of the main control device 20 specifies the game content to be played by the pachinko machine 10, and is a so-called model change in which the game content is changed by exchanging a game board or the like. It is a dedicated board that sometimes needs to be replaced. On the other hand, the control board accommodated in the protective case 22 of the power supply control device 21 controls power supply to the control devices 20 and 27 and can be used between different models. It is a common board that sometimes does not require replacement. Further, one side edge (the right edge in FIG. 3) of the protective case 22 of the main control device 20 protrudes from the side edge toward the outside of the case at two locations separated in the vertical direction. Support portions 24 and 24 are formed, and first engagement holes (second engagement portions) 24a and 24a penetrating in the front-rear direction are formed in the support portions 24 and 24, respectively. Further, the other side edge portion (left side edge portion in FIG. 2) of the protective case 22 of the main control device 20 protrudes substantially perpendicularly to the side edge portion at two locations that are separated from each other in the vertical direction (that is, FIG. 2) (first projecting portions 25, 25 projecting to the left).

  The mechanism set board 30 is formed in a rectangular shape that substantially matches the outer shape of the middle frame 12, and the back surface of the game board faces the back of the pachinko machine 10 through a window 31 that is opened in the approximate center. It is configured. Further, a ball tank 32 for storing pachinko balls supplied from an external ball supply facility is disposed on the upper side of the mechanism set board 30, and the pachinko balls in the ball tank 32 are placed on the right side of the window 31. The upper ball tray and the lower ball tray are supplied through a ball passage 33 provided in the section. Further, an accommodation recess 34 that is recessed forward is formed on the mechanism set panel 30 below the window 31 (see FIG. 2).

  The opening size of the housing recess 34 is such that it substantially matches the surface of the power supply control device 21 facing the mechanism set board 30, and the depth dimension of the housing recess 34 in the front-rear direction is that of the power supply control device 21. It is set larger than the length dimension in the front-rear direction. That is, as shown in FIG. 3, the power supply control device 21 can be completely accommodated in the accommodation recess 34. Further, an attachment portion 35 for removably attaching the main control device 20 is formed in the mechanism set panel 30 in the vicinity of the accommodating recess 34, and the main control device 20 is connected to the main control device 20 via the attachment portion 35. The power supply control device 21 is attached in a positional relationship overlapping with the front and rear (see FIGS. 1 to 3). In the first embodiment, the power supply control device 21 is detachably disposed in the housing recess 34 by a conventionally known engagement means, screwing, or the like.

  Further, between the power supply control device 21 housed in the housing recess 34 and the main control device 20 attached to the attachment portion 35, a conductive material such as a metal plate is used as shown in FIGS. The formed noise shielding shield member 40 is arranged to prevent the noise generated in the power supply control device 21 from reaching the main control device 20, and the noise generated in the main control device 20 is controlled by the power supply. It does not reach the device 21. That is, in the pachinko machine 10 according to the first embodiment, as shown in FIGS. 1 to 4, the power supply control device 21 that does not require replacement when changing the model is disposed between the shield member 40 and the mechanism set panel 30. At the same time, the main controller 20 that needs to be replaced at the time of change is arranged on the opposite side of the shield member 40 from the mechanism set board 30 (that is, outside the pachinko machine 10).

  As shown in FIG. 3, the attachment portion 35 is an engagement protrusion (first engagement portion) that is detachably engaged with the first engagement holes 24a, 24a formed in the main controller 20. ) 36, 36, 39, 39, and openings 38, 38 into which the first protrusions 25, 25 formed in the main controller 20 can be inserted. In the first embodiment, the engaging protrusions 36, 36, 39, 39 are formed at four positions that are spaced apart in the vertical direction. The main control device 20 is used for mounting, and the two engaging protrusions 39 and 39 therebetween are used for mounting the payout control device 27. Here, since the shape of the engagement protrusion 36 for attaching the main control device 20 and the engagement protrusion 39 for attaching the payout control device 27 are the same, only the engagement protrusion 36 of the main control device 20 will be described. The engaging protrusions 36, 36 oppose the upper and lower positions of the rear surface 30 a of the mechanism setting panel 30 in the vicinity of the receiving recess 34 (on the right side of the receiving recess 34 in FIG. 3 or 4). It consists of a pair of hooks 37, 37 that can be elastically deformed in the direction and protrude rearward, and claw portions 37 a, 37 a are formed on the surfaces of the hooks 37, 37 that do not face each other. The claw portions 37a and 37a have rear end surfaces of the support portions 24 and 24 when the engagement protrusions 36 and 36 (hooks 37 and 37) are inserted into the first engagement holes 24a and 24a. The claw portions 37a and 37a are in contact with the rear end surfaces of the support portions 24 and 24, thereby restricting rearward movement of the main control device 20.

  The openings 38 are spaced apart in the vertical direction at the rear end of the wall 34a (the left side of the housing recess 34 in FIG. 3 or 4) that defines the housing recess 34 in the mechanism set board 30. Two openings are formed so as to open toward the engagement protrusions 36, 36. Therefore, when the first protrusions 25 and 25 formed in the main controller 20 are inserted into the openings 38 and 38, the first protrusions 25 and 25 are formed on the inner surfaces of the openings 38 and 38, respectively. The main controller 20 does not move backward. That is, the first engagement holes 24a and 24a and the first protrusions 25 and 25 of the main controller 20 are engaged with the corresponding engagement protrusions 36 and 36 and the openings 38 and 38, respectively. Thus, the main controller 20 is attached to the mechanism set panel 30 (attachment portion 35). In the first embodiment, the openings 38 and 38 are formed at a position rearward of the back surface of the power supply control device 21 disposed in the housing recess 34, and are attached via the openings 38 and 38. The control device 20 (shield member 40) is configured not to interfere with the power supply control device 21.

  The shield member disposed between the power control device 21 and the main control device 20 covers substantially the entire surface of the main control device 20 facing the power control device 21, as shown in FIG. 2 or FIG. The noise is generated from the power supply control device 21 to prevent the main control device 20 from malfunctioning. The shield member 40 includes a second engagement hole (third engagement portion) 41 that can be engaged with the engagement protrusion 36 formed in the mechanism set board 30, and the openings 38 and 38. And the second protrusions 42 and 42 can be inserted into the openings 38 and 38 of the mechanism set board 30 in the same manner as the main controller 20 described above. In this state, the engagement protrusion 36 and the second engagement hole 41 are engaged with each other to be attached at a predetermined position.

  Here, the second engagement hole 41 is composed of a pair of engagement pieces 41a and 41a spaced apart by a predetermined distance in the vertical direction, and the engagement pieces 41a and 41a are claw portions 37a and 41a of the engagement protrusion 36, respectively. It is comprised so that it may contact | abut 37a. In the first embodiment, the second engagement hole 41 is formed only at a position corresponding to the engagement protrusion 36 formed on the upper side, and the engagement protrusion 36 formed on the lower side. At the corresponding position, a through hole 43 through which the engaging protrusion 36 is inserted is formed. That is, the shield member 40 is prevented from falling off from the attachment portion 35 by the engagement of the second engagement hole 41 and the engagement protrusion 36.

  Further, as shown in FIG. 2, the second projecting portions 42, 42 are provided corresponding to the openings 38, 38 formed in the mechanism set board 30, and from the second engagement hole 41. Inclined surfaces 42a, 42a are formed which incline toward the mechanism set panel 30 as they are separated. That is, in the state where the second protrusions 42, 42 are inserted into the openings 38, 38, the opening width gradually increases from the opening end of the openings 38, 38 toward the inside ( (See FIG. 4 (b)).

[Operation of Example 1]
Next, the operation of the gaming machine according to the first embodiment will be described below. When the pachinko machine 10 is turned on, the power supply control device 21 converts the current values and voltage values appropriate for the electrical components of the control devices 20, 27, etc., and supplies power to the control devices 20, 27, etc. Supply. Then, the player operates the handle unit 18 to strike a pachinko ball on the game board, thereby developing a required game.

  By the way, since the power supply control device 21 changes the current value and the voltage value, noise is likely to occur. For this reason, if the main control device 20 is arranged in a positional relationship overlapping with the power supply control device 21 in the front-rear direction, the main control device 20 may malfunction due to noise from the power supply control device 21 as it is. Therefore, in the pachinko machine 10 according to the first embodiment, a conductive material is formed between the power supply control device 21 as a noise generation source and the main control device 20 to be protected from noise from the power supply control device 21. Since the shield member 40 is disposed to block noise, the main controller 20 can be prevented from malfunctioning. Further, since the shield member 40 is formed so as to cover substantially the entire rear surface of the power supply control device 21, noise from the power supply control device 21 is completely blocked, and the main control device 20 is suitably protected from noise. Can do. Similarly, there is also a possibility that noise is generated from the main control device 20, but noise generated due to the main control device 20 can also be blocked by the shield member 40, and therefore the power control device 21 is caused by the noise. Can be prevented from malfunctioning.

  When the main control device 20 and the power supply control device 21 are arranged side by side on the back surface 30a of the mechanism set panel 30, the installation area for the mechanism set panel 30 is increased, and the installation space for other members is reduced. turn into. Therefore, if the main control device 20 and the power supply control device 21 are arranged so as to overlap each other as in the first embodiment, a space margin is generated on the back surface (surface direction) of the mechanism set panel 30. The degree of freedom of installation of other members on the set board 30 is improved. Therefore, various members can be arranged with a margin with respect to the mechanism set board 30, and new members that are not conventionally provided can be installed.

  By the way, the main controller 20 that controls the entire pachinko machine 10 needs to particularly prevent unauthorized modification, and the protection case 22 is formed of a transparent resin material so that the inside can be visually observed. The control board built in the protective case 22 is inspected for abnormalities such as circuit patterns. Here, in the first embodiment, the shield member 40 and the main controller 20 are independently and detachably attached via the attachment portion 35 formed on the mechanism set panel 30. The control board of the main control device 20 can be confirmed simply by removing the main control device 20 from the attachment portion 35. That is, when the shield member 40 is attached to the main control device 20 so as to be attachable / detachable or pivotable as in the prior art, the main control device 20 is provided with a mechanism for checking the control board of the main control device 20. Although it is necessary to remove the shield member 40 and turn the shield member 40 to visually observe the inside of the main control device 20 after the set board 30 (mounting portion 35) is removed, the configuration according to the first embodiment described above. According to the above, since it is only necessary to remove the main controller 20 from the mechanism set panel 30 (attachment portion 35), there is an advantage that workability is improved and the inspection work of the control board can be performed quickly and easily.

  Further, when the above-described model change is performed or when a failure such as failure or damage occurs in the main control device 20, it is necessary to perform replacement / maintenance work of the main control device 20. Here, in the first embodiment, the power supply control device 21 is disposed between the shield member 40 and the mechanism set board 30 (that is, the housing recess 34), and the shield member 40 is opposite to the mechanism set board 30. The main control device 20 is disposed on the mechanism set panel 30 as a separate member from the main control device 20. For this reason, even when the main controller 20 is replaced or maintained, only the main controller 20 needs to be removed without removing the shield member 40 from the mechanism set panel 30. In addition, the shield member 40 is not lost. Further, since the shield member 40 remains attached to the mechanism set panel 30 (attachment portion 35), the shield member 40 can be used as it is even if the main control device 20 is replaced, thereby preventing an increase in waste and cost. obtain.

  Further, when the shield member 40 is attached to the mechanism set panel 30 via the attachment portion 35 for attaching the main control device 20, the outer shape of the main control device 20 is changed when the model is changed. Even so, there is no need to change the shape of the shield member 40 as long as the main controller 20 can be attached to the attachment portion 35. In this case as well, there is an advantage that waste and cost can be suppressed. Further, by attaching the shield member 40 to the mechanism set panel 30, the shape and the like can be arbitrarily determined without being trapped by the weight of the shield member 40. Therefore, it is possible to configure the shield member 40 to have a large thickness dimension so as to reliably block noise from the power supply control device 21. In addition, since the shield member 40 is configured not to be handled integrally with the main control device 20, the weight of the main control device 20 does not increase even when the weight of the shield member 40 is increased. There is no possibility that the convenience of storage, transportation, attachment to the pachinko machine 10, etc. of the main controller 20 will be reduced.

  Next, a method for attaching the main controller 20 and the shield member 40 to the mechanism set panel 30 will be described. With the second protrusions 42, 42 formed on the shield member 40 being inserted into the openings 38, 38 formed on the mechanism set board 30, the engagement protrusions 36, 36 of the mechanism set board 30 are The shield member 40 is inserted into each of the second engagement hole 41 and the through hole 43 (see FIG. 4A). At this time, the engagement pieces 41a and 41a of the second engagement hole 41 are engaged with the claw portions 37a and 37a of the engagement protrusion 36, and the shield member 40 is moved to the mechanism set board 30 (the attachment portion 35). (See FIG. 4 (b)). In this state, the first protrusions 25 and 25 formed in the main controller 20 are inserted into the openings 38 and 38, and the engagement protrusions 36 and 36 are connected to the first engagement of the main controller 20. It inserts in each of the joint holes 24a and 24a (refer FIG.4 (c)). At this time, the claw portions 37a, 37a of the engagement protrusions 36, 36 abut against the first engagement holes 24a, 24a, and the hooks 37, 37 are elastically deformed in a direction close to each other, and When the claw portions 37a, 37a come out of the first engagement holes 24a, 24a, the hooks 37, 37 are elastically restored, and the claw portions 37a, 37a are supported to form the first engagement holes 24a, 24a.
