Description

  The present invention relates to a gaming machine board case in which a board housing space for housing a control board is formed inside by combining a case body and a lid member.

  Conventionally, a control board for controlling the operation of a gaming machine such as a pachinko machine or a slot machine is mounted in an appropriate position such as the back side of the gaming machine while being accommodated in a gaming machine board case.

  Therefore, the board case for gaming machines is generally formed into a hollow box structure in which a case body is combined with a lid member and an opening of the case body is covered with the lid member. In addition, in such a gaming machine substrate case, various measures have been conventionally taken in order to prevent an illegal act on the control substrate accommodated therein.

  Specifically, for example, as shown in Patent Document 1, cylindrical portions are provided in each of the case main body and the lid member to be assembled thereto, and lock pins are inserted into these cylindrical portions and fixedly held. As a result, there is known a board case for gaming machines in which relative displacement between the case body and the lid member (displacement in the direction in which the board case is opened) is prevented, and illegal actions on the accommodated control board are prevented. It has been.

  Moreover, in order to stabilize the sealing state by the lock pin, a pair of opening operation prevention mechanisms using such a lock pin is generally provided as shown in Patent Document 1. is there.

  By the way, in the gaming machine substrate case, it may be necessary to open the gaming machine substrate case after being brought into a sealed state by a lock pin. For example, when there is an inspection by a predetermined inspection organization, it is necessary to open the gaming machine substrate case and take out the control substrate accommodated therein.

  Therefore, as described in Patent Document 1, the opening of the gaming machine substrate case is generally performed by either one of the cylindrical portion provided in the case body and the cylindrical portion provided in the lid member. Is separated from the board case for gaming machines. Thereby, the trace that the board case for gaming machines was opened can be left in the board case for gaming machines.

  However, in the gaming machine substrate case described in Patent Document 1, the cylinder portion separated from the gaming board case when the sealing state of the gaming machine substrate case is released is provided only in either the case body or the lid member. Since this is not done, the following problems occur.

  In other words, the employees of the gaming hall where the gaming machine is installed can use the trace of the opening of the gaming machine substrate case to inspect and maintain the control board accommodated in the gaming machine board case. However, depending on the mounting position of the board case for the gaming machine on the back side of the gaming machine, it is difficult to see the trace of opening the board case for the gaming machine, which makes it difficult to manage. .

  Although it is possible to remove the gaming machine substrate case from the gaming machine and check the trace of opening, there is a problem that the detaching operation of the gaming machine substrate case is troublesome. In addition, since a large number of gaming machines are installed in the gaming hall, it is not realistic to perform confirmation work on all gaming machines in this way.

  Here, the present invention has been made in the background as described above, and the problem to be solved is that it is difficult to adversely affect the work of confirming the opened trace by the attachment position to the gaming machine or the like. An object of the present invention is to provide a gaming machine board case having a novel structure.

  Hereinafter, the aspect of this invention made | formed in order to solve such a subject is described. In addition, the component employ | adopted in each aspect as described below is employable by arbitrary combinations as much as possible.

  The present invention has a box structure in which a lid member is assembled to a case main body and has a board housing space, and a gaming board control board is housed in the board housing space. In the case, the case main body is provided with a main body side cylinder portion, and the lid member is provided with a lid side cylinder portion at a position corresponding to the main body side cylinder portion of the case main body. In the assembled state, the internal spaces of the main body side cylindrical portion and the lid side cylindrical portion are connected to each other, and the connecting member is inserted in the axial direction across the main body side cylindrical portion and the lid side cylindrical portion, and the inserted state At least a pair of opening operation blocking mechanisms that are prevented from opening the lid member relative to the case body by blocking the relative displacement between the body side cylinder portion and the lid side cylinder portion by the connecting member. Vs. Among the opening operation blocking mechanisms to be performed, one opening operation blocking mechanism separates the lid-side cylinder portion from the lid member, thereby releasing the blocking operation state of the lid member with respect to the case body by the one opening operation blocking mechanism. On the other hand, the other opening operation prevention mechanism separates the main body side cylindrical portion from the case body, so that the other opening operation prevention mechanism releases the blocking state of the lid member opening operation on the case body. The opening of the lid member with respect to the case main body is canceled in both of the paired opening operation blocking mechanisms, so that the lid member can be opened with respect to the case main body. , Feature.

  In the case of the gaming machine substrate case structured according to the present invention, when releasing the state in which the opening operation of the lid member with respect to the case main body is blocked by the one opening operation blocking mechanism, the lid side cylinder portion is When the state in which the opening operation of the lid member with respect to the case main body is blocked by the other opening operation blocking mechanism is released, the main body side cylinder portion is separated from the case main body. Thus, when the opening operation blocking state is released by one opening operation blocking mechanism, it is possible to leave a trace in which the lid side cylindrical portion is separated on the lid member, and the other opening operation blocking mechanism When the opening operation blocking state is released, it is possible to leave a trace in which the main body side cylinder portion is separated in the case main body.

  That is, in the gaming machine substrate case according to the present invention, the trace of the opening operation blocking state by the opening operation blocking mechanism is left on both the case body and the lid member constituting the gaming machine substrate case. In addition, since the opening operation blocking state is not canceled in both of the paired opening operation blocking mechanisms, the opening operation of the lid member with respect to the case body cannot be performed. It is only necessary to confirm the trace that the opening operation blocking state by the opening operation blocking mechanism has been released in any one of them, and the trace that has released the opening operation blocking state by the opening operation blocking mechanism is the mounting position of the board case for gaming machines, etc. Therefore, it is possible to advantageously avoid the difficulty of confirmation.

In addition, the spring pin 92 as a lock pin can be fitted into the second main body side cylinder part 34 and the second lid side cylinder part 56 positioned on the same central axis as described above. ing. In the present embodiment, the spring pin 92 fitted into the first main body side cylinder portion 32 and the first lid side cylinder portion 54, the second main body side cylinder portion 34, and the second lid side cylinder portion 56. Since the spring pins 92 fitted into the same are the same, only one spring pin 92 will be described, and the detailed description of the other spring pin 92 will be omitted.

  The spring pin 92 of this embodiment is made of steel, spring steel, spring stainless steel, or the like, and is meandering in the axial direction in a part of the circumferential direction as shown in FIGS. It has a cylindrical shape in which an extending cut 94 is formed. Note that such a spring pin 92 is advantageously formed by, for example, rounding a plate material in which both ends in the longitudinal direction are formed in a sawtooth shape using an appropriate machine or tool. Further, the spring pin 92 of the present embodiment is chamfered over the entire circumference with respect to the outer corners at both ends in the axial direction, so that from either side of both ends in the axial direction.

  As a result, a force for tightening the spring pin 92 acts on a portion of the spring pin 92 that is fitted into the lower housing portion 60 of the first lid-side cylinder portion 54. As a result, a force (restoring force) for the spring pin 92 to return to the original shape acts on the lower housing portion 60 of the first lid-side cylinder portion 54.

  Then, the restoring force by the spring pin 92 as described above acts on the lower housing portion 60 of the first lid-side cylinder portion 54, so that the outer peripheral surface of the spring pin 92 is below the first lid-side cylinder portion 54. It will be pressed against the inner peripheral surface of the accommodating part 60. As a result, a frictional force is generated between the outer peripheral surface of the spring pin 92 and the inner peripheral surface of the lower housing portion 60 of the first lid-side cylinder portion 54 in a direction that prevents displacement of the spring pin 92. .

  Then, as described above, when the spring pin 92 is further inserted against the frictional force from the state in which the spring pin 92 is inserted into the lower housing portion 60 of the first lid-side cylinder portion 54, as shown in FIG. As shown, the spring pin 92 is inserted across the first lid side cylinder portion 54 and the first main body side cylinder portion 32.

  Therefore, in the present embodiment, as described above, the spring pin 92 is inserted across the first lid-side cylinder portion 54 and the first main body-side cylinder portion 32, and the first in the spring pin 92. A force for tightening the spring pin 92 acts only on the portion fitted in the lower housing portion 60 of the lid-side cylinder portion 54. That is, in this embodiment, the frictional force that prevents the axial displacement of the spring pin 92 is exerted only on the portion of the spring pin 92 that is fitted in the lower housing portion 60 of the first lid side cylinder portion 54. As a result, in this embodiment, the spring pin 92 is fitted and fixed to the first lid side cylinder portion 54 (lower accommodation portion 60) only by press fitting.

  In the present embodiment, as described above, the spring pin 92 is inserted across the first lid side cylinder portion 54 and the first main body side cylinder portion 32, and the spring pin 92 is the first lid side. One end in the axial direction of the spring pin 92 is positioned in the first lid side cylindrical portion 54 while being fitted and fixed to the side cylindrical portion 54, and the other in the axial direction of the spring pin 92. Is positioned in the first main body side cylinder portion 32. Thereby, the opening operation of the lid member 14 with respect to the case main body 12 is inserted over the first lid side cylinder portion 54 and the first main body side cylinder portion 32 and is fixedly held in that state. It will be blocked by the spring pin 92. That is, in the present embodiment, the first lid side cylinder portion 54, the first main body side cylinder portion 32, and the spring pin 92 constitute one opening operation prevention mechanism 102.

  Furthermore, in this embodiment, when the spring pin 92 is further fitted from the state shown in FIG. 14, both longitudinal ends of the plate-like piece 98 in the assembly pin 96 fixed to the spring pin 92 are It is made to slide with respect to a pair of opposing wall part 104,104 which is made to oppose in the longitudinal direction (left-right direction in FIG. 14) in the upper side accommodating part 58 of the one cover side cylinder part 54. As shown in FIG.

  Therefore, in the present embodiment, the distance between the opposing surfaces of the pair of opposing wall portions 104, 104 is gradually shortened from the upper opening of the upper accommodating portion 58 of the first lid side cylinder portion 54 to the bottom wall. Has been. As a result, the longitudinal ends of the plate-like piece 98 of the assembly pin 96 fixed to the spring pin 92 gradually go to the first lid as they go to the bottom wall side of the upper housing portion 58 of the first lid-side cylinder portion 54. Warpage of the upper side accommodating portion 58 of the side cylinder portion 54 toward the upper opening side is increased.

  Then, when the plate-like piece 98 reaches the bottom wall of the upper accommodating portion 58 of the first lid-side cylinder portion 54, both longitudinal ends of the plate-like piece 98 are above the first lid-side cylinder portion 54. While returning from the state which warped the upper opening side of the accommodating part 58 to the original state, it enters into the opening hole 106 formed in the bottom wall vicinity of each opposing wall part 104. As shown in FIG. As a result, both end portions in the longitudinal direction of the plate-like piece 98 are formed on the inner peripheral surface of the opening hole 106 formed in each opposing wall portion 104 (particularly, on the side opposite to the insertion direction of the spring pin 92). The assembly pin 96 is displaced to the upper opening side of the upper housing part 58 in the first lid side cylinder part 54 by being locked to the opening side surface). The upward displacement (displacement in the pulling direction) is prevented.

  In the present embodiment, the state shown in FIG. 14, that is, the spring pin 92 is fitted into the first lid-side cylinder portion 54, and the upper surface of the plate-like piece 98 is the first lid-side cylinder portion 54. A gap is formed between both ends in the width direction of the plate-like piece 98 and the upper accommodating portion 58 of the first lid-side cylinder portion 54 in a state of being positioned at the same height as the upper end surface of the first lid-side cylinder portion 54. In particular, in the present embodiment, both ends in the longitudinal direction of the plate-like piece 98 from the state where the upper surface of the plate-like piece 98 is positioned at the same height as the upper end surface of the first lid-side cylinder portion 54 (upper accommodation portion 58). Until each enters the opening hole 106, a gap is formed between both ends in the width direction of the plate-like piece 98 and the upper accommodating portion 58 of the first lid-side cylinder portion 54. It has become. Thus, only the both longitudinal ends of the plate-like piece 98 are in the first state until the spring pin 92 is inserted across the first lid side cylinder portion 54 and the first main body side cylinder portion 32. One lid side cylinder portion 54 is warped toward the upper opening side of the upper accommodation portion 58. As a result, the spring pin 92 is inserted across the first lid side cylinder portion 54 and the first main body side cylinder portion 32 from the state where the spring pin 92 is fitted in the first lid side cylinder portion 54. It is possible to reduce the resistance to the state.

  Further, as described above, the spring pin 92 with the assembly pin 96 assembled is, as shown in FIG. 16, the second main body from the other end side in the axial direction where the assembly pin 96 is not attached. It is also inserted into the side tube portion 34.

  As a result, a force for tightening the spring pin 92 acts on a portion of the spring pin 92 that is fitted in the upper housing portion 44 of the second main body side cylindrical portion 34. As a result, a force (restoring force) that the spring pin 92 tries to return to the original shape acts on the upper accommodating portion 44 of the second main body side cylindrical portion 34.

  The restoring force of the spring pin 92 as described above acts on the upper housing portion 44 of the second main body side cylindrical portion 34, so that the outer peripheral surface of the spring pin 92 is the upper housing portion in the second main body side cylindrical portion 34. It will be pressed against the inner peripheral surface of 44. As a result, a frictional force is generated between the outer peripheral surface of the spring pin 92 and the inner peripheral surface of the upper housing portion 44 in the second main body side cylindrical portion 34 in a direction that prevents displacement of the spring pin 92.

  Then, as described above, when the spring pin 92 is further inserted against the frictional force from the state in which the spring pin 92 is inserted into the upper housing portion 44 of the second main body side cylinder portion 34, it is shown in FIG. As shown, the spring pin 92 is inserted across the second main body side cylinder portion 34 and the second lid side cylinder portion 56.

  Therefore, in the present embodiment, as described above, the spring pin 92 is inserted across the second main body side cylindrical portion 34 and the second lid side cylindrical portion 56, and the second pin is set in the spring pin 92. A force for tightening the spring pin 92 acts only on a portion of the main body side cylinder portion 34 that is fitted in the upper housing portion 44. That is, in this embodiment, the frictional force that prevents the axial displacement of the spring pin 92 is applied only to the portion of the spring pin 92 that is fitted in the upper housing portion 44 of the second main body side cylindrical portion 34. As a result, in this embodiment, the spring pin 92 is fitted and fixed to the second main body side cylindrical portion 34 (upper accommodating portion 44) only by press fitting.

  In the present embodiment, as described above, the spring pin 92 is inserted across the second main body side cylindrical portion 34 and the second lid side cylindrical portion 56, and the spring pin 92 is connected to the second main body side. One end in the axial direction of the spring pin 92 is positioned in the second main body side cylindrical portion 34 while being fitted and fixed to the side cylindrical portion 34, and the other axial direction of the spring pin 92 is positioned in the other side. The end portion is positioned in the second lid side cylinder portion 56. Thereby, the opening operation of the lid member 14 with respect to the case main body 12 is inserted over the second main body side cylinder portion 34 and the second main lid side cylinder portion 56 and fixedly held in that state. It will be blocked by the spring pin 92. That is, in the present embodiment, the second main body side cylinder portion 34, the second lid side cylinder portion 56, and the spring pin 92 constitute the other opening operation prevention mechanism 108.

  Furthermore, in this embodiment, when the spring pin 92 is further fitted from the state shown in FIG. 16, both longitudinal ends of the plate-like piece 98 in the assembly pin 96 fixed to the spring pin 92 are It is made to slide with respect to a pair of opposing wall part 110,110 which is made to oppose in the longitudinal direction (left-right direction in FIG. 16) in the lower accommodating part 42 of the 2nd main body side cylinder part 34. As shown in FIG.

  Therefore, in the present embodiment, the distance between the opposing surfaces of the pair of opposing wall portions 110 and 110 gradually increases from the lower opening of the lower housing portion 42 of the second main body side cylindrical portion 34 to the upper bottom wall. It is designed to be shorter. As a result, both longitudinal ends of the plate-like piece 98 in the assembly pin 96 fixed to the spring pin 92 gradually become second as they go to the upper bottom wall side of the lower accommodating portion 42 in the second main body side cylindrical portion 34. In the main body side cylindrical portion 34, warpage of the lower accommodating portion 42 toward the lower opening side is increased.

  When the plate-like piece 98 reaches the upper bottom wall of the lower accommodating portion 42 in the second main body side cylindrical portion 34, each of the longitudinal end portions of the plate-like piece 98 becomes the second main body side cylindrical portion 34. In addition to returning from the state of warping the lower opening side of the lower accommodating portion 42 to the original state, each of the opposing wall portions 110 enters the opening holes 112 formed in the vicinity of the upper bottom wall. As a result, both end portions in the longitudinal direction of the plate-like piece 98 are arranged on the inner peripheral surface of the opening hole 112 formed in each opposing wall portion 110 (particularly, on the side opposite to the insertion direction of the spring pin 92). The assembly pin 96 is displaced to the lower opening side of the lower accommodating portion 42 in the second main body side cylindrical portion 34, and consequently the spring pin 92. The upward displacement in the axial direction (displacement in the removal direction) is prevented.

  In the present embodiment, the state shown in FIG. 16, that is, the spring pin 92 is fitted into the second main body side cylindrical portion 34, and the lower surface of the plate-shaped piece 98 is the second main body side cylindrical portion 34. A gap is formed between the both ends in the width direction of the plate-like piece 98 and the lower housing part 42 of the second main body side cylinder part 34 in a state where it is positioned at the same height as the lower end surface of the second main body side cylinder part 34. In particular, in the present embodiment, the longitudinal direction of the plate-like piece 98 from the state in which the lower surface of the plate-like piece 98 is positioned at the same height as the lower end surface of the second main body side cylindrical portion 34 (lower accommodation portion 42). Until each of both ends enters the opening hole 112, a gap is formed between both ends in the width direction of the plate-like piece 98 and the lower accommodating portion 42 of the second main body side cylindrical portion 34, respectively. It is like that. As a result, only the both longitudinal ends of the plate-like piece 98 are in the first state until the spring pin 92 is inserted across the second main body side cylinder portion 34 and the second lid side cylinder portion 56. The second main body side cylindrical portion 34 warps to the lower opening side of the lower accommodating portion 42. As a result, the spring pin 92 was inserted across the second main body side cylindrical portion 34 and the second lid side cylindrical portion 56 from the state where the spring pin 92 was fitted in the second main body side cylindrical portion 34. It is possible to reduce the resistance to the state.

  In the gaming machine substrate case 10 having such a structure, the center extending in a direction intersecting the sliding displacement direction of the lid member 14 relative to the case body 12 in a state where the lid member 14 is assembled to the case body 12. A spring pin 92 inserted across the first lid-side cylinder portion 54 and the first main body-side cylinder portion 32 positioned on the axis is a lower housing portion 60 in the first lid-side cylinder portion 54. The second main body side cylinder portion 34 and the second lid side which are fitted and fixed to each other and positioned on the central axis extending in the direction intersecting the sliding displacement direction of the lid member 14 with respect to the case main body 12 Since the spring pin 92 that is inserted across the tube portion 56 is fitted into the upper housing portion 44 of the second body-side tube portion 34 and is press-fitted and fixed, the lid member 1 for the case body 12 Is displaced by the spring pin 92 constituting one opening operation prevention mechanism 102 and the spring pin 92 constituting the other opening operation prevention mechanism 108, that is, a pair of opening operation prevention mechanisms 102. As a result, the sealed state of the gaming machine substrate case 10 is realized. Incidentally, in the present embodiment, one open operation blocking mechanism 102 and the other open operation blocking mechanism 108 are provided in each of the four, so that there are a total of four open operation blocking mechanisms 102 and 108 in pairs. Thus, the sealed state of the gaming machine substrate case 10 can be realized four times.

  On the other hand, in order to release the sealed state of the gaming machine substrate case 10, a pair of attachment pieces 62 connecting the first lid side cylinder portion 54 constituting one opening operation prevention mechanism 102 to the lid member 14. , 62 are cut with a nipper or the like, and the spring pin 92 inserted in the first main body side cylinder portion 32 is extracted together with the first lid side cylinder portion 54, and the opening operation blocking state by one opening operation blocking mechanism 102 is removed. And the pair of attachment pieces 46, 46 connecting the second main body side cylinder portion 34 constituting the other opening operation blocking mechanism 108 to the case main body 12 is cut with a nipper or the like, This is realized by removing the spring pin 92 inserted into the lid side cylinder part 56 together with the second main body side cylinder part 34 and releasing the opening operation blocking state by the other opening operation blocking mechanism 108.

  Therefore, in the gaming machine substrate case 10 having the above-described structure, when the sealed state is released, the trace remains on both the case body 12 and the lid member 14, and the gaming machine substrate case 10 is attached. Depending on the position and the like, it can be advantageously avoided that it is difficult to confirm the trace of the release of the sealed state of the gaming machine substrate case 10.

  Therefore, in the present embodiment, since the spring pin 92 that generates a spring action in the direction perpendicular to the axis is employed as the lock pin, the lower housing portion 60 and the second main body in the first lid side cylinder portion 54 are used. Even if there is a dimensional error during molding in the upper housing portion 44 in the side cylinder portion 34 or there is a change in the ambient temperature of the board case 10 for gaming machines, the axial displacement of the spring pin 92 is advantageously prevented. It becomes. As a result, a stable sealed state of the gaming machine substrate case 10 can be advantageously realized.
