Description

  The present invention relates to a gaming machine board case for protecting an electronic board of a gaming machine, and a gaming machine using the gaming machine board case.

  Various electronic boards such as a main control board and a sub-control board are accommodated in a housing of a gaming machine such as a spinning machine or a pachinko machine. When these electronic boards or ROMs attached to the electronic boards are replaced with counterfeit goods, for example, a general player (a player who does not know the specific operation) performs a specific operation on the gaming machine. However, there is a possibility that a malicious player (a player who knows the specific operation) may be allowed to play an illegal game, such as making it possible to modify the gaming machine so that the game proceeds under advantageous conditions. For this reason, each manufacturer of gaming machines stores various electronic boards including the main control board in a case (board case) to take measures to prevent unauthorized access to the electronic board.

  On the other hand, an electronic board stored in the board case may be provided with a rotary switch for various settings. For example, Patent Document 1 describes a gaming machine in which a rotary switch for changing gaming specifications of a gaming machine is provided on a power supply board (power supply unit). In conventional gaming machines, in order to be able to adjust this type of rotary switch even from the outside of the board case, the entire knob portion of the rotary switch is exposed from the opening provided at the position overlapping the rotary switch in the board case. The structure is used.

  However, in a conventional gaming machine having such a structure, when performing operations such as cleaning the inside of the gaming machine housing, supplying a medal to the medal hopper, or canceling an error, the operator's body or the tool protrudes from a knob portion. There is a drawback that the rotary switch is damaged or easily peeled off from the substrate due to accidental collision. In particular, medals supply and error clearing work are often performed with the player sitting in front of the gaming machine, and it is necessary to work with the front door half open, so the hand is narrow and working. In addition, the problem is that the rotary switch is easily broken or peeled off from the substrate. Such a problem is likely to occur particularly when the rotary switch is provided only in a state where it is soldered to the electronic board.

JP 2007-105334 A (FIG. 4)

  The present invention has been made in order to solve the above-mentioned problems, and has a protective function capable of preventing damage to the rotary switch or peeling from the board while ensuring the operability of the rotary switch. A case is provided. It is also an object of the present invention to provide a gaming machine in which an electronic board is accommodated in the gaming machine board case.

The above issues
A board case for a gaming machine for protecting a board housed inside a gaming machine housing,
A rotary switch protector for covering the top of the rotary switch attached to the substrate and protecting the rotary switch;
This can be solved by providing a board case for a gaming machine characterized in that a knob operation opening for operating a knob portion of the rotary switch is provided on the side of the rotary switch protection section.

  In such a configuration, by covering the upper part of the rotary switch, it is possible to protect the rotary switch including the upper end of the knob portion that is most required to be protected from external force. The knob part has a certain length to ensure operability. However, when a lateral external force is applied to this part, the principle of the hook works and the rotary switch base (the part attached to the board) ) Is easy to apply a large force. The force applied to the rotary switch base is maximized when a lateral external force is applied to the upper end of the knob portion.In the present invention, the protection including the upper end of the knob portion protects the rotary switch. Peeling from the substrate can be effectively prevented. Further, since the side surface of the knob portion is exposed through the knob operation opening, it is possible to directly contact the side surface of the knob portion, which is a normal operation location, and to achieve high operability.

  In the board case for gaming machines of the present invention, the opening for knob operation can be provided on both lateral sides of the rotary switch protection part. In such a configuration, the knob portion can be operated from both sides, and the operability can be improved.

In the gaming machine substrate case of the present invention, as described above, when the knob operation openings are provided on both sides of the rotary switch protection part, the width W ₁ of the rotary switch protection part (see FIG. 7) is set. It is preferable that the diameter φ _{1 of the} knob portion (see FIG. 7) is approximately equal. This is because when the width W ₁ of the rotary switch protection portion is significantly smaller than the diameter φ ₁ of the knob portion, the protrusion width W ₂ (see FIG. 7) of the knob portion is increased, so that the rotary switch is sufficiently There is a possibility that not be sufficiently protected, if this remarkably greater than the width W ₁ in diameter phi ₁ Conversely, where there is likely to impair the operability becomes painful contact with the knob portion, the rotary switch with this configuration This is because it is possible to achieve both protection function and operability in a suitable balance.

  In the board case for gaming machines of the present invention, the rotary switch protection part is formed separately from the main body part of the board case, and the protective part mounting opening provided at a position overlapping the knob part of the rotary switch in the board case It can also be made to be mountable to the In such a configuration, even if there is a change in the installation location of the substrate case or the layout around the substrate case, the rotary switch protection of a suitable size or shape without changing the substrate case main body. It becomes possible to select and install a part.

In the gaming machine substrate case of the present invention, the end surface of the knob operation opening can be formed in an inwardly inclined shape. In other words, the end face of the knob operation opening is inclined so that the inner width W ₃ (see FIG. 7) of the rotary switch protection portion is smaller than the width W ₁ (see FIG. 7) of the rotary switch protection portion. You can also. In such a configuration, it is possible to facilitate contact with the knob portion while keeping the protrusion width W ₂ (see FIG. 7) of the knob portion small, and it is possible to improve operability.

  The board case for a gaming machine of the present invention described above can be suitably used as a part that protects a part to be protected in various gaming machines such as a swivel type gaming machine and a pachinko gaming machine.

2.1.2 Protective Cap FIG. 5 is an enlarged perspective view showing the positional relationship between the protective cap 120 and the rotary switch 210 in the gaming machine board case 100 of the first embodiment. FIG. 6 is a three-plane projection view of the protective cap 120 and the rotary switch 210 in the gaming machine substrate case 100 of the first embodiment. As shown in FIGS. 5 and 6, the protective cap 120 is protected by fitting into a rotary switch protective part 121 for protecting the rotary switch 210 and a protective part mounting opening 130 in the board case main body 110. An attachment base 122 for fixing the cap 120 to the substrate case main body 110 is provided. Here, the rotary switch protection unit 121 refers to a portion that is exposed outward from the outer surface of the substrate case main body 110 when the protective cap 120 is attached to the substrate case main body 110 (see FIG. 8). The attachment base 122 refers to a portion that is embedded in the substrate case main body 110 and is not exposed when the protective cap 120 is attached to the protective part attachment opening 130 of the substrate case main body 110. A knob operation opening 121 c for operating the knob portion 211 of the rotary switch 210 is provided on the side of the rotary switch protection section 121.

  The shape of the rotary switch protection unit 121 is not particularly limited as long as the rotary switch protection unit 121 can cover and protect the rotary switch 210 and has at least one knob operation opening 121c. In the gaming machine substrate case 100 of the aspect, as shown in FIGS. 5 and 6, a pair of knob operation openings 121 c are formed at opposing positions on both sides thereof. For this reason, the rotary switch protection part 121 has a form in which an upper protection part 121a for protecting the upper side of the rotary switch 210 and a side protection part 121b for covering and protecting the side are connected in a band shape. Yes. As a result, the knob portion 211 can be operated with fingers or the like sandwiched from both sides, and higher operability can be realized.

  Further, in the gaming machine substrate case 100 of the first embodiment, as shown in FIG. 6C, a gap is provided between the rotary switch protection part 121 and the knob portion 211 of the rotary switch 210, The rotary switch protection unit 121 does not directly contact the knob portion 211. As a result, even when an external force is applied to the rotary switch protection unit 121, it is possible to prevent the external force from being transmitted to the knob portion 211.

  Here, although the side protection part 121b may be formed in parallel to the side surface of the knob part 211, it is preferable that the side protection part 121b is inclined in a divergent shape as shown in FIG. Thereby, the external force applied in the lateral direction with respect to the rotary switch protection unit 121 can be dispersed, and a higher rotary switch protection function can be provided. It is also possible to prevent hands and the like from being caught during work. The corner formed by the upper protection part 121a and the side protection part 121b may be pointed, but is preferably a smooth curved surface. Thereby, said catch etc. can be prevented more suitably.

  The shape of the side edge 121d (see FIG. 6A) of the rotary switch protection unit 121 may be a straight line, but may be a shape including an inclination, a bulge, a curve, a constriction, and the like. For example, in the gaming machine substrate case 100 of the first embodiment, the side edge 121d of the rotary switch protection part 121 swells in an arc shape in a portion overlapping the upper surface of the knob portion 211 as shown in FIG. I'm out. As a result, not only can the upper end of the knob portion 211 be protected more firmly, but also the location where the knob portion 211 is located can be recognized from the outside of the rotary switch protector 121 and the rotary switch 210 is operated by groping. In this case, the knob portion 211 can be easily found. In the gaming machine substrate case 100 of the first embodiment, the side edge 121d of the rotary switch protection part 121 is inclined outward in the vicinity of the mounting base 122 as shown in FIG. The root part of the rotary switch protection part 121 is thick in the width direction. Thereby, the intensity | strength of the rotary switch protection part 121 itself can be raised.

Here, the AA plane is a plane including the upper end surface of the knob portion 211 of the rotary switch 210. The width W ₁ of the rotary switch protection unit shown in FIG. 7 is not particularly limited in size. However, if significantly smaller than the diameter phi ₁ of the knob portion 211 of the rotary switch 210 width W _1, becomes larger width W ₂ protruding knob portion 211, not be sufficiently protect the rotary switch 210 There is a fear. For this reason, the value of the difference φ ₁ −W ₁ between the diameter φ ₁ and the width W ₁ is preferably 1 mm or less, more preferably 0.5 mm or less. On the other hand, there is a possibility that it becomes painful and may contact width W ₁ when conspicuously larger than the diameter phi _1, the portion 211 knob through knob operation opening section 121c. For this reason, the value of the difference W ₁ −φ ₁ between the width W ₁ and the diameter φ ₁ is preferably 1 mm or less, more preferably 0.5 mm or less.

The shape and size of the knob operation opening 121c are not particularly limited as long as the knob part 211 of the rotary switch 210 can be operated through the opening 121c, but the knob part 211 can be easily operated by a fingertip or the like. Therefore, as shown in FIG. 6C, when the protective cap 120 is viewed laterally from the side toward the knob operation opening 121c, at least the entire upper portion of the knob portion 211 passes through the knob operation opening 121c. It is preferable that the size be exposed. Specifically, the area of the knob operation opening 121c is preferably 0.3 cm ² or more. However, if the knob operation opening 121c is too large, the rotary switch 210 may not be sufficiently protected. Therefore, the area of the knob operation opening 121c is preferably 1.5 cm ² or less.

The shape of the end surface 121c _{1 of the} knob operation opening 121c (the side end surface of the rotary switch protection unit 121. The portion shown by hatching in FIG. 6C) is the shape of the knob portion 211 through the knob operation opening 121c. Although there is no particular limitation as long as it does not hinder the operation, the gaming machine substrate case 100 of the first embodiment has an inwardly inclined shape as shown in FIG. In other words, as the width W ₁ of the rotary switch protection section is larger than the inner width W ₃ of the rotary switch protection section _(see Figure 7), the end surface 121c ₁ of the knob operation opening portion 121c is inclined. Thus, while maintaining reduce the width W ₂ protruding knob portion 211, it becomes possible to facilitate contact by a finger or the like with the knob portion 211.

  The shape of the attachment base portion 122 in the protective cap 120 is not particularly limited as long as it can be fitted into the protective portion mounting opening 130. In the gaming machine substrate case 100 of the first embodiment, the attachment base 122 is formed so that the outer peripheral surface thereof is along the protective part mounting opening 130 as shown in FIGS. 3 and 6A. It has become an annular body. The rotary switch base 212 (see FIG. 5) is arranged in the center of the mounting base 122 made of an annular body.

  FIG. 8 is a cross-sectional view of the periphery of the rotary switch protector 121 in the gaming machine substrate case 100 of the first embodiment, cut along a plane corresponding to the BB plane in FIG. The outer peripheral surface 122a of the mounting base 122 may be formed parallel to the center line of the knob portion 211 (parallel to the z axis), but as shown in FIG. 8, the lower diameter is larger than the upper diameter. It is preferable to incline so as to have a large taper shape. In this case, the inner peripheral surface 131 of the protective part mounting opening 130 is also inclined corresponding to the outer peripheral surface 122a of the attachment base. As a result, the protective cap 120 can be easily attached to the substrate case main body 110, and the efficiency of assembly work in a factory or the like can be increased. In addition, the protective cap 120 can be firmly fitted into the protective portion mounting opening 130.

  By the way, in the board case 100 for gaming machines of the first embodiment, as shown in FIGS. 5 and 6, a part on the hem side of the mounting base 122 is bulged outwardly to provide a tongue-shaped portion 122 b. Yes. For this reason, as shown in FIG. 8, in the state where the protective cap 120 is mounted on the substrate case main body 110, the upper surface of the tongue-shaped portion 122b is the back side of the edge of the protective unit mounting opening 130 (the substrate case main body). 110 a back surface). Thereby, when attaching the protective cap 120 from the lower side of the substrate case main body 110, the protective cap 120 can be prevented from being pushed upward from a predetermined position. Further, since it is possible to make it difficult to pull the protective cap 120 upward, it is possible to prevent unauthorized access by removing the protective cap 120. At this time, it is preferable that the lower end of the attachment base 122 is in contact with a portion where the load on the relay board 200 may be applied (see FIG. 8). In the gaming machine substrate case 100 of the first embodiment, as shown in FIGS. 5 and 6, a pattern wiring (illustrated) extending from the terminal 214 of the rotary switch or the terminal 124 in the bottom end of the mounting base 122. The wiring escape recess 122c is provided at a position overlapping with (not shown) and the like, and the other portions are in contact with the relay board 200. Thus, when a downward external force is applied to the protective cap 120, the protective cap 120 is prevented from falling off without affecting the terminal 214 of the rotary switch, wiring (not shown), or the like. It becomes possible.
