Description

  The present invention relates to a technology of a substrate case that is formed by assembling a case main body and a lid member, and includes a caulking portion cover that covers a caulking portion that fixes the case main body and the lid member.

  Conventionally, in a gaming machine such as a pachinko machine or a throttle machine, a board case formed by assembling a case body and a lid member is used as a member for housing a control board. Various techniques relating to the substrate case are known in order to prevent illegal acts on the control board accommodated in the substrate case.

  For example, a substrate case (substrate box) formed by assembling a case main body (first box constituent member) and a lid member (second box constituent member) by the technique described in Patent Document 1 is provided in the case main body. The case-side cylindrical portion (caulking portion) and the lid-side cylindrical portion (caulking portion) provided on the lid member are arranged to face each other, and the one-way screw straddles the case-side cylindrical portion and the lid-side cylindrical portion. It is fixed by screwing into the slender state. The substrate case is provided with a caulking part cover (adhering part cover) that covers the case side cylinder part and the lid side cylinder part. The caulking part cover suppresses an illegal act on the case side cylinder part and the lid side cylinder part, that is, an act of illegally releasing the fixing of the case side cylinder part and the lid side cylinder part, to the control board stored in the board case. To suppress fraud. The caulking portion cover is attached to the substrate case with attachment screws.

  However, in such a configuration, the caulking portion cover can be easily removed from the substrate case by removing the mounting screw. Therefore, the fixing of the case side cylinder part and the lid side cylinder part covered with the caulking part cover is illegally released, and there is a possibility that an illegal act is performed on the control board stored in the board case. Further, after such a fraudulent act is performed, when the caulking portion cover is reattached to the substrate case by the mounting screw, the caulking portion cover is removed, that is, the case side tube covered with the caulking portion cover. The person in charge at the game hall or the like where this gaming machine is located, indicating that there is a risk that fraudulent acts may have been performed on the control board stored in the board case. However, there was a problem that it was difficult to confirm afterwards.

  Therefore, it is considered that the caulking portion cover is not a mounting screw, but a snap pin which is a known technique is provided on the substrate case, and the snap pin and the caulking portion cover are snap-coupled to attach the caulking portion cover to the substrate case. It is done. That is, when the caulking part cover is removed from the board case, the snap pins are cut even if the caulking part cover is removed by an illegal act if the snap pins that are snap-coupled must be cut. Therefore, if the person confirms the cutting trace of the snap pin, the person in charge is illegally released from the fixing of the case side cylinder part and the lid side cylinder part to the control board stored in the board case. It can be easily confirmed visually that there has been a risk of being performed.

  However, if the snap pin provided on the substrate case and snap-coupled to the caulking portion cover is not cut but is urged toward the anti-bonding direction and elastically deformed, the snap-pin coupling with the caulking portion cover is not possible. It may be possible to cancel. In such a case, even if the caulking part cover is removed from the board case, there is no cut mark on the snap pins, and after the caulking part cover is removed from the board case, the caulking part is utilized using the snap pins. The cover can be reattached (locked) to the substrate case. That is, in such a case, there is a problem that it is difficult for the person in charge to visually confirm that the caulking portion cover has been once removed from the substrate case.

  The present invention has been made in view of the above problems, and the problem to be solved is formed by assembling the case body and the lid member, and caulking the case body and the lid member. Provided is a substrate case that includes a caulking portion cover that covers the portion, and that can easily visually confirm that the caulking portion cover has been removed.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

That is, according to claim 1, in the substrate case formed by assembling the case main body and the lid member, the caulking portion is provided on one side surface of the case main body and the lid member and caulks the case main body and the lid member. And in a state where the one surface is opened in a substantially box shape, the opened surface is directed to one side surface of the case body and the lid member, and the caulking portion is accommodated therein, and the case body and the A caulking portion cover that is locked to the lid member, and the caulking portion cover protrudes from the one side surface of the case main body or the lid member into the caulking portion cover; and have the locked portion that engages so as not to release inside of the caulking portion cover, on the side facing the locking portion in the crimping part cover, positions on both sides sandwiching the opposing portion between the locking portion In addition, Through hole penetrating through the side surface is formed, the object to be locked part from the side viewed in the locking portion of the caulking cover the through hole is formed is located in the rear of the locking unit, wherein By cutting the facing portion and the locking portion, the locking of the caulking portion cover with respect to one side surface of the case body or the lid member can be released.

As shown in FIG. 9 (b), the main body side accommodating part 222 and the second main body side cylinder part 221 are arranged around the main body side accommodating part 222 and formed in a substantially double cylindrical shape whose axial direction is the front-rear direction. The Here, the second main body side caulking portion 220 is reduced in diameter from the rear to the front in accordance with the shapes of the second main body side accommodating portion 222 and the second main body side cylindrical portion 221 in the inner cylindrical portion. However, the front side that is the side facing the lid member 3 is opened, and the rear side that is the side opposite to the lid member 3 is opened. The outer cylindrical portion of the second main body side frame 223 is opened. Depending on the shape, the front side that faces the lid member 3 is opened, the rear side that is opposite to the lid member 3 is opened, and the lower side is further opened.

  The second lid side caulking portion 230 is disposed on the front side of the second caulking portion 200 as shown in FIGS. 6 and 8 to 11. The second lid side caulking portion 230 is provided on the lid member 3. The second lid side caulking portion 230 includes a second lid side frame 233, a second lid side accommodating portion 232, and a second lid side cylindrical portion 231.

  As shown in FIG. 6, the second lid side cylinder portion 231 is formed in a substantially cylindrical shape with a lid whose front side is closed by a closing portion 235 and whose rear side is opened. The second lid-side cylinder portion 231 is disposed above the top plate of the lid member 3 (the top plate of the substrate case 1) with the axial direction as the front-rear direction.

The second lid side accommodating portion 232 is formed in a substantially cylindrical shape with the front and rear sides and the upper side opened. The second lid-side accommodating portion 232 is disposed immediately above the second lid-side cylindrical portion 231 with the axial center direction being the front-rear direction above the top plate of the lid member 3. It is provided so that it may continue. The second lid side accommodating portion 232 is formed to have a larger diameter than the second lid side cylindrical portion 231 so that the outer peripheral shape of the lower portion protrudes downward, and communicates with the second lid side cylindrical portion 231.
Further, as shown in FIGS. 10 and 11, the lengths in the front, rear, left, and right and up and down directions of the inner diameter of the second lid side accommodating portion 232 are the outside of the second main body side cylindrical portion 221 of the second main body side caulking portion 220. The length is set to be slightly longer than the length in the front-rear, left-right, and vertical directions. Further, the lengths of the second lid-side housing portion 232 in the front-rear, left-right, and vertical directions are the lengths in the front-rear, left-right, and vertical directions of the inner diameter of the second body-side frame 223 of the second body-side caulking portion 220. Shorter than this. And all the 2nd lid side accommodating parts 232 are comprised so that accommodation in the 2nd main body side frame 223 is possible, and substantially all the 2nd main body side cylinder parts 221 can be engage | inserted in the 2nd lid side accommodating part 232. Configured.

The second lid side frame 233 is formed in a substantially rectangular tube shape with the front and rear sides and the upper side opened. The second lid side frame 233 is disposed immediately after the second lid side accommodating portion 232 with the axial direction as the front-rear direction above the top plate of the lid member 3. It is provided so as to be continuous forward and backward. The second lid side frame 233 is formed with a larger diameter than the second lid side accommodating portion 232 and communicates with the second lid side accommodating portion 232. The second lid side frame 233 is directly fixed to the top plate of the lid member 3.
As shown in FIGS. 10 and 11, the length of the outer diameter of the second lid side frame 233 in the front-rear direction and the vertical direction is equal to the inner diameter of the second main body side frame 223 of the second main body side crimping portion 220. The length is set slightly shorter than the length in the front-rear and up-down directions. The second lid side frame 233 is configured to be fitted into the second main body side frame 223.

  Thus, the second lid side caulking portion 230 is configured by successively connecting the second lid side cylindrical portion 231, the second lid side accommodating portion 232, and the second lid side frame body 233 from the front to the rear. As a whole, it is formed in a substantially cylindrical shape whose axial direction is the front-rear direction. Here, the second lid side caulking portion 230 is stepwise from the front to the rear in accordance with the shapes of the second lid side cylindrical portion 231, the second lid side accommodating portion 232, and the second lid side frame body 233. While expanding the diameter, the front side opposite to the case main body 2 is closed, and the rear side opposite to the case main body 2 is opened.

  In such a configuration, when the substrate case 1 is assembled as described above, when the upper portion of the lid member 3 is slid upward while being fitted to the case body 2, the second lid side caulking portion of the lid member 3 is used. 230 moves upward as the lid member 3 slides, and is fitted into the second body side caulking portion 220 of the case body 2 from below as shown in FIGS. 10 and 11. Specifically, the entire second main body side cylindrical portion 221 is fitted in the second lid side accommodating portion 232, and the second lid side accommodating portion 232 is accommodated in the second main body side frame 223. Then, the front end portion of the second main body side accommodating portion 222 is fitted into the second lid side frame body 233. At this time, the second main body side accommodating portion 222 is not fitted into the second lid side accommodating portion 232, and the second main body side cylindrical portion 221 is not fitted into the second lid side cylindrical portion 231. Thus, when the case main body 2 and the lid member 3 are assembled, the second caulking portion 200 fits the rear portion of the second lid side caulking portion 230 into the front portion of the second main body side caulking portion 220 from below. The second lid side caulking portion 230 is formed so as to be aligned substantially in a straight line with the second main body side caulking portion 220.

  Further, in the second caulking portion 200, the second lid side cylinder portion 231 is disposed on the substantially same axis as the second main body side cylinder portion 221 in front of the second main body side cylinder portion 221, and the second main body side. The tube portion 221 is communicated. That is, the second caulking portion 200 communicates from the second main body side accommodating portion 222 located at the rearmost portion to the second lid side cylindrical portion 231 located at the foremost portion, and has a lid with the axial direction as a whole in the front-rear direction. It is formed in a substantially cylindrical shape. Here, the second caulking portion 200 has a closed portion 235 on the front side and has a shape that opens the rear side.

  Next, the structure of the fitting member 50 inserted in the 1st crimping part 100 and the 2nd crimping part 200 is demonstrated using FIG.

The fitting member 50 is formed by assembling a spring pin 51 and an assembly pin 52. The width in the axial direction of the fitting member 50 is set slightly smaller than the front-rear width of the first main body side caulking portion 120.
The spring pin 51 is a substantially cylindrical member made of steel or spring steel. A notch 51a is formed in a part of the outer peripheral surface of the spring pin 51 so as to extend while meandering in the axial direction. The outer diameter of the spring pin 51 in the natural state is set to be slightly larger than the inner diameters of the first main body side cylinder portion 121 and the first lid side cylinder portion 131. The spring pin 51 has elasticity, and when a force is applied from the outer peripheral side of the spring pin 51 to the radially inner side (the direction in which the width of the notch 51a is reduced), the spring pin 51 is elastically deformed in the direction in which the force is applied. When the spring pin 51 is elastically deformed radially inward, the spring pin 51 has a restoring force outward in the radial direction (direction in which the width of the cut 51a increases).
The assembly pin 52 is made of a synthetic resin material such as ABS and has flexibility. The assembly pin 52 is formed by extending the insertion shaft 54 from the central portion of the plate-like piece 53 formed in a substantially square plate shape. The diameter of the plate-like piece 53 is set to be slightly larger than the outer diameter of the spring pin 51 and slightly larger than the inner diameters of the first lid side accommodation portion 132 and the second main body side accommodation portion 222. The assembly pin 52 is assembled with the spring pin 51 by inserting the insertion shaft 54 from the opening on one side of the spring pin 51 and fixing the plate-like piece 53 to one end of the spring pin 51. .

  Next, fixing of the case main body 2 and the lid member 3 will be described with reference to FIG.

  The case main body 2 and the lid member 3 are fixed by inserting the fitting member 50 into the first caulking portion 100 and the second caulking portion 200, respectively, and the first main body side caulking portion 120 and the first lid of the first caulking portion 100. The side caulking portion 130 is caulked, and the second main body side caulking portion 220 and the second lid side caulking portion 230 of the second caulking portion 200 are caulked.

Specifically, when the case body 2 and the lid member 3 are assembled when the substrate case 1 is assembled, in the group on the left side of the caulking portion 10, the first lid side caulking portion 130 has a rear portion thereof. The first caulking part 100 is assembled in a state of being fitted in the front part of the first main body side caulking part 120 so that the first caulking part 120 is arranged in a substantially straight line before and after communicating with the first main body side caulking part 120. It is formed in a substantially cylindrical shape with a bottom having the center direction as the front-rear direction.
Then, the fitting member 50 is fitted into the first caulking portion 100 from the front opening, that is, the front opening of the first lid side accommodating portion 132 with the spring pin 51 as the rear side.
At this time, since the diameter of the plate-like piece 53 is set to be slightly larger than the inner diameter of the first lid-side accommodating portion 132, the fitting member 50 bends the left and right outer peripheral portions of the plate-like piece 53 to the first lid side. It is inserted into the first caulking portion 100 while being in contact with the inner peripheral surface of the housing portion 132 (while the left and right end portions of the plate-like piece 53 are warped forward).
When the rear part of the spring pin 51 of the fitting member 50 passes through the first lid side cylinder part 131 and reaches the first main body side cylinder part 121, the plate-like piece 53 returns the bending of the left and right outer peripheral parts. (That is, the left and right end portions of the plate-like piece 53 are not warped forward and the shape of the plate-like piece 53 is restored), and is fitted into the openings 136 on the left and right side walls of the first lid-side accommodation portion 132. . Thus, the fitting member 50 is prevented from coming off from the first caulking portion 100.

When the fitting member 50 is fitted into the first caulking portion 100, the inner diameter of the first main body side cylindrical portion 121 and the inner diameter of the first lid side cylindrical portion 131 are set slightly smaller than the outer diameter of the spring pin 51 in the natural state. Therefore, the spring pin 51 fitted in the first main body side cylinder portion 121 and the first lid side cylinder portion 131 is elastically deformed in a direction in which the diameter is reduced (inward in the radial direction).
In this state, the restoring force of the spring pin 51 of the fitting member 50, that is, the force directed outward in the radial direction of the spring pin 51, and the reaction of each of the first main body side cylindrical portion 121 and the first lid side cylindrical portion 131. Due to the force, a frictional force is generated between the outer peripheral surface of the spring pin 51 and the inner peripheral surfaces of the first main body side cylindrical portion 121 and the first lid side cylindrical portion 131.

With such a configuration, the fitting member 50 is held by the first caulking portion 100 in a state of straddling between the first main body side cylindrical portion 121 and the first lid side cylindrical portion 131, and the first main body side caulking portion 120. And the first lid side caulking portion 130 are caulked, and the case body 2 and the lid member 3 are fixed.
Further, the fitting member 50 does not easily move forward from the state straddling between the first main body side cylinder portion 121 and the first lid side cylinder portion 131. Therefore, once the first main body side caulking portion 120 and the first lid side caulking portion 130 are caulked, the fitting member 50 is removed from the first caulking portion 100 to fix the case main body 2 and the lid member 3. It cannot be easily released.

Further, when the case body 1 and the lid member 3 are assembled when the substrate case 1 is assembled, the second lid side caulking portion 230 and the rear portion of the caulking portion 10 are connected to the second main body when the case main body 2 and the lid member 3 are assembled. The first caulking part 100 is assembled so that the first caulking part 100 as a whole is aligned in a straight line while communicating with the second main body side caulking part 220 in a state of being fitted to the front part of the side caulking part 220. It is formed in a substantially cylindrical shape with a lid in the front-rear direction.
Then, the insertion member 50 is inserted into the first caulking portion 100 from the rear opening, that is, the rear opening of the second main body side housing portion 222 with the spring pin 51 as the front side.
At this time, since the diameter of the plate-like piece 53 is set to be slightly larger than the inner diameter of the second main body side accommodating portion 222, the fitting member 50 bends the left and right outer peripheral portions of the plate-like piece 53 to the second main body side. While being brought into contact with the inner peripheral surface of the accommodating portion 222 (while the left and right end portions of the plate-like piece 53 are warped backward), the fitting is inserted into the second caulking portion 200.
When the front part of the spring pin 51 of the fitting member 50 passes through the second main body side cylinder part 221 and reaches the second lid side cylinder part 231, the plate-like piece 53 returns the bending of the left and right outer peripheral parts. (That is, the left and right end portions of the plate-like piece 53 are not warped backward, and the shape of the plate-like piece 53 is restored) and is fitted into the openings 226 on the left and right side walls of the second main body side housing portion 222. It is. Thus, the fitting member 50 is prevented from coming off from the second caulking portion 200.

When the fitting member 50 is fitted into the second caulking portion 200, the inner diameter of the second main body side cylindrical portion 221 and the inner diameter of the second lid side cylindrical portion 231 are set slightly smaller than the outer diameter of the spring pin 51 in the natural state. Therefore, the spring pin 51 fitted in the second main body side cylinder part 221 and the second lid side cylinder part 231 is elastically deformed in the direction in which the diameter is reduced (inward in the radial direction).
In this state, the restoring force of the spring pin 51 of the fitting member 50, that is, the force directed outward in the radial direction of the spring pin 51, and the reaction of each of the second main body side cylindrical portion 221 and the second lid side cylindrical portion 231. Due to the force, a frictional force is generated between the outer peripheral surface of the spring pin 51 and the inner peripheral surfaces of the second main body side cylindrical portion 221 and the second lid side cylindrical portion 231.

With such a configuration, the fitting member 50 is held by the second caulking part 200 in a state of straddling between the second main body side cylindrical part 221 and the second lid side cylindrical part 231, and the second main body side caulking part 220. And the second lid side caulking portion 230 are caulked, and the case body 2 and the lid member 3 are fixed.
Further, the fitting member 50 does not easily move rearward from the state straddling between the second main body side cylinder portion 221 and the second lid side cylinder portion 231. Therefore, once the second main body side caulking portion 220 and the second lid side caulking portion 230 are caulked, the fitting member 50 is removed from the second caulking portion 200 to fix the case main body 2 and the lid member 3. It cannot be easily released.

  Next, release of the fixation between the lid member 3 and the case body 2 will be described with reference to FIG.

  The lid member 3 and the case main body 2 are released from being fixed without removing the fitting member 50 from the first caulking portion 100 and the second caulking portion 200, and the first lid side caulking portion 130 of the first caulking portion 100 is covered with the lid member 3. The lid side connecting piece 135 to be connected to 3 and the main body side connecting piece 225 for connecting the second main body side caulking portion 220 of the second caulking portion 200 to the case main body 2 are cut.

Specifically, after the substrate case 1 is assembled, when the lid-side connecting piece 135 on the first caulking portion 100 side is cut by a tool such as a nipper, the first caulking portion 100 is caulked by the first lid-side caulking portion. The first lid side accommodation part 132 of the part 130 is separated from the top plate of the lid member 3 and detached from the lid member 3.
At this time, the spring pin 51 of the fitting member 50 is in the first main body side cylinder portion 121 in a state where the first lid side cylinder portion 131 of the first lid side caulking portion 130 is fitted in the first main body side cylinder portion 121. Since the plate-like piece 53 of the fitting member 50 is fitted into the opening 136 of the first lid-side accommodating portion 132, the first lid-side caulking portion 130 is inserted into the first lid-side cylindrical portion 131. It is connected to the case body 2 via a first body side caulking portion 120. However, since the first lid side accommodating portion 132 is detached from the lid member 3, the first caulking portion 100 (the first main body side caulking portion 120 and the first lid side caulking portion 130) is provided only on the case main body 2. Then, the case body 2 and the lid member 3 are released from being fixed.

Further, after the substrate case 1 is assembled, when the main body side connecting piece 225 on the second caulking portion 200 side is cut by a tool such as a nipper, the second caulking portion 200 has a second caulking portion 220 of the second main body side caulking portion 220. The second main body side accommodating portion 222 is separated from the second main body side frame 223 and the top plate of the case main body 2 and detached from the lid member 3.
In this state, the second main body side cylindrical portion 221 of the second main body side caulking portion 220 is fitted in the second lid side accommodating portion 232, and the spring pin 51 of the fitting member 50 is in the second lid side cylindrical portion. Since the plate-like piece 53 of the fitting member 50 is fitted into the opening 226 of the second main body side accommodating portion 222, the second main body side caulking portion is inserted into the inner portion 231 and the second main body side cylindrical portion 221. 220 is connected to the lid member 3 via a second lid side caulking portion 230. However, since the second main body side accommodating portion 222 is detached from the case main body 2, the second caulking portion 200 (the second main body side caulking portion 220 and the second lid side caulking portion 230) is provided only on the lid member 3. Then, the case body 2 and the lid member 3 are released from being fixed.

  Next, a configuration for attaching the caulking portion cover 5 to the substrate case 1 will be described.

Further, the vertical length of the inner diameter of the caulking portion cover 5 is set slightly longer than the length from the top plate of the substrate case 1 to the uppermost end portion of the caulking portion 10. Thus, the length of the inner diameter of the caulking portion cover 5 in the left, right, front, rear, and upper and lower directions is set to a length that allows the plurality of caulking portions 10 to be collectively covered from the outside.

Next, the structure of the locking piece insert 70 provided in the caulking portion cover 5 will be described in more detail.
In the present embodiment, a total of six locking piece inserts 70 are provided. In the following description, only the configuration of the locking piece insertion body 70 disposed on the rear side of the two locking piece insertion bodies 70 formed on the right side of the right side plate 65 of the caulking portion cover 5 will be described. . About the structure of the other latching piece insertion body 70, the description is abbreviate | omitted by attaching | subjecting the code | symbol same as a code | symbol used in description of the latching piece insertion body 70 arrange | positioned in the said back side by drawing.

  As shown in FIG. 19, among the six inner locking pieces 82 provided on the top plate of the substrate case 1, the corresponding locking piece insert 70 is inserted and locked. Is. The locking piece insertion body 70 is formed in a substantially rectangular tube shape having an opening on the lower side, and is formed on the right side of the right side plate 65 of the caulking portion cover 5. The locking piece insert 70 formed on the right side of the right side plate 65 is disposed on the rear side of the right side plate 65 of the caulking portion cover 5 in the front-rear direction. At the front lower end portion of the locking piece insert 70, a substantially rectangular tube-shaped member (referred to as “front square tube portion 71” in the following description) having an opening on the rear side and the lower side protrudes forward. In addition, a substantially rectangular tube-like member (referred to as “rear square tube portion 72” in the following description) whose front and lower sides are opened at the rear lower end portion of the locking piece insert 70 is directed rearward. Projected. The front square tube portion 71 and the rear square tube portion 72 are formed substantially symmetrically with respect to the front and rear center portion of the locking piece insert 70.

  A pair of front and rear through holes 75 are formed in the right side plate of the front square tube portion 71 and the right side plate of the rear square tube portion 72. The pair of front and rear through holes 75 penetrates the right side plate of the front square tube portion 71 and the right side plate of the rear square tube portion 72, that is, the right side plate of the locking piece insert 70 in the left-right direction, and is substantially square in a side view. Formed. Between the through-hole 75 of the front square cylinder part 71 and the through-hole 75 of the rear square cylinder part 72, the latching piece coating | coated part 73 which is a part of right side board of the latching piece insertion body 70 is provided. The locking piece covering portion 73 is a portion that covers the inner locking piece 82 so that the inner locking piece 82 cannot be directly seen in a side view in a state where the inner locking piece 82 is inserted into the locking piece insert 70. The length in the front-rear direction of the locking piece covering portion 73 is set to be substantially the same as or longer than the length in the front-rear direction of the inner locking piece 82. Further, in a state where the inner locking piece 82 is inserted into the locking piece insertion body 70, there is almost no gap between the inner locking piece 82 and the locking piece insertion body 70.

  The front rectangular tube portion 71 communicates with the front and rear central portions of the locking piece insert 70, that is, the inside of the locking piece covering portion 73 in the locking piece insert 70 through the opening on the rear side. Further, the rear rectangular tube portion 72 communicates with the front and rear central portions of the locking piece insert 70, that is, the inside of the locking piece covering portion 73 in the locking piece insert 70 through the opening on the front side. That is, the front square tube portion 71 and the rear square tube portion 72 are communicated with each other through the front and rear center portions of the locking piece insert 70, that is, the inside of the locking piece covering portion 73 of the locking piece insert 70.

A space formed in a substantially rectangular parallelepiped shape with the longitudinal direction being the vertical direction is provided in the front and rear central portion of the locking piece insert 70, that is, inside the locking piece covering portion 73 of the locking piece insert 70. The inner locking piece 82 is inserted into the space.
Therefore, the front and rear, left and right, and vertical lengths of the inner diameter of the locking piece insert 70 (the space) are substantially the same as the front and rear, left and right, and vertical directions of the outer diameter of the inner locking piece 82, or slightly. Set long. In other words, in a state where the inner locking piece 82 is inserted into the locking piece insert 70, the outer peripheral surface of the inner locking piece 82 and the inner peripheral surface of the locking piece insert 70 are set so as to substantially contact each other. Is done. With such a configuration, in a state where the inner locking piece 82 is inserted into the locking piece insertion body 70, the inner locking piece 82 is biased in any direction regardless of the direction, and the locking piece insertion body 70. Since it abuts against the inner peripheral surface of the plate, it is formed so as not to be elastically deformed.

  An opening 74 is formed in the upper part of the left side plate of the locking piece insert 70. The opening 74 penetrates the left side plate of the locking piece insert 70 in the left-right direction and is formed in a substantially rectangular shape in side view. The opening 74 is provided with a locking piece receiving portion 79 that is a substantially plate-like elastic member. The locking piece receiving portion 79 protrudes from the lower edge of the opening 74 toward the upper right side, that is, toward the inner locking piece 82 side with its plate surface directed in the left-right direction. The upper end surface of the locking piece receiving portion 79 is a substantially horizontal plane.

  Next, locking between the caulking portion cover 5 and the substrate case 1 will be described.

As shown in FIG. 19, the caulking portion cover 5 and the substrate case 1 are locked by inserting an inner locking piece 82 of the substrate case 1 into the locking piece insert 70.
When the inner locking piece 82 is inserted into the locking piece insertion body 70, the upper end portion of the inner locking piece 82 is the front and rear center of the lower end portion of the locking piece insertion body 70, that is, the locking piece insertion body 70. Is inserted into the locking piece covering portion 73 from the inside thereof. The inner locking piece 82 inserted into the locking piece insertion body 70 moves inside the locking piece insertion body 70 while sliding the claw portion 84 of the inner locking piece 82 upward. Then, when the claw portion 84 of the inner locking piece 82 comes into contact with the locking piece receiving portion 79 of the locking piece insertion body 70 (the diameter is increased toward the locking piece receiving portion 79 as it goes downward). The claw portion 84 moves upward while pressing the locking piece receiving portion 79, which is an elastic member, to the left side, that is, in a direction away from the claw portion 84 of the inner side locking piece 82 to be elastically deformed. Further, when the inner locking piece 82 moves upward and the claw portion 84 of the inner locking piece 82 is positioned above the locking piece receiving portion 79, the locking piece receiving portion 79 of the claw portion 84 is moved. The locking piece receiving portion 79 that has been released and is elastically deformed is restored to the right side, that is, in the direction approaching the claw portion 84 of the inner locking piece 82, and the claw portion 84 of the inner locking piece 82. And the locking piece receiving portion 79 of the locking piece insert 70 are locked.

  In the state where the claw portion 84 of the inner locking piece 82 and the locking piece receiving portion 79 of the locking piece insert 70 are locked by such a configuration, the bottom surface of the claw portion 84 formed in a substantially horizontal plane, The upper end surface of the locking piece receiving portion 79 formed in a substantially horizontal plane is in contact with the upper end surface in a plan view. Therefore, once the claw portion 84 of the inner locking piece 82 and the locking piece receiving portion 79 of the locking piece insert 70 are locked, the locking is not easily released (the inner locking piece 82 is engaged). The structure is such that it cannot be removed from the stopper insert 70.

Since the total of the six inner locking pieces 82 and the locking piece inserts 70 in the present embodiment are formed in substantially the same shape, all the inner locking pieces 82 are attached when the caulking portion cover 5 is attached to the substrate case 1. The locking piece 82 and the locking piece insertion body 70 are locked substantially simultaneously. Further, when the caulking portion cover 5 is attached to the substrate case 1, the outer locking piece 81 (the claw portion 83) together with the inner locking piece 82 of the substrate case 1 becomes the locking piece receiving portion 66 of the caulking portion cover 5. Locked.
As a result, the caulking portion cover 5 is locked by the two outer locking pieces 81 and the six inner locking pieces 82 of the board case 1 and attached to the board case 1.

  Next, release of the engagement between the caulking portion cover 5 and the substrate case 1 will be described.

  In order to remove the caulking portion cover 5 from the substrate case 1, it is necessary to unlock the caulking portion cover 5 and the substrate case 1. As shown in FIG. 20, the engagement between the caulking portion cover 5 and the substrate case 1 is not removed from the engagement piece insertion body 70 of the caulking portion cover 5 in the inner engagement piece 82 of the substrate case 1. This is done by cutting the inner locking piece 82 locked to the locking piece insert 70 of the caulking portion cover 5.

  Specifically, in a state where the caulking portion cover 5 is attached (locked) to the substrate case 1, first, a cutting edge of a tool such as a nipper is inserted into the pair of front and rear through holes 75 of the locking piece insert 70. The lower end portion of the right side plate of the locking piece insert 70 provided between the pair of front and rear through holes 75, that is, the locking piece covering portion 73 of the locking piece insert 70 is cut. And if the latching piece coating | coated part 73 is removed, the front-and-rear center part of the latching piece insertion body 70 in which the lower end part of the inner side latching piece 82 is inserted is the front square cylinder part 71 and the rear square cylinder part. 72, the cutting edge of a tool such as a nipper is inserted into the front square tube portion 71 and the rear square tube portion 72, and the lower end portion of the inner locking piece 82 is cut.

In this way, even when the claw portion 84 of the inner locking piece 82 and the locking piece receiving portion 79 of the locking piece insert 70 are locked, when the inner locking piece 82 is cut, it is initially integrated. Since the inner locking piece 82 and the substrate case 1 formed separately are separated, the locking between the substrate case 1 and the caulking portion cover 5 is released. Therefore, in the present embodiment, since a total of six inner locking pieces 82 and the locking piece inserts 70 are provided, all these locking piece covering portions 73 and the inner locking pieces 82 are cut. By doing so, the engagement between the substrate case 1 and the caulking portion cover 5 by the inner engagement piece 82 is released.
Further, since the outer locking piece 81 of the substrate case 1 is disposed outside the caulking portion cover 5, the outer locking piece 81 is directed toward the non-locking side, that is, the locked substrate case. When the outer locking piece 81 is elastically deformed by being urged away from the one locking piece receiving portion 79, the outer locking piece 81 is detached from the locking piece receiving portion 79, and the substrate case 1 and the caulking portion cover 5 are separated. The lock is released.
In this way, the locking of the substrate case 1 and the caulking portion cover 5 by all the inner locking pieces 82 is released, and the locking of the substrate case 1 and the caulking portion cover 5 by all the outer locking pieces 81 is released. Then, the caulking portion cover 5 can be removed from the substrate case 1.

  Finally, the function and effect of the substrate case 1 configured as described above will be described.

  The substrate case 1 is a substrate case formed by assembling a case main body 2 and a lid member 3, and a main body side caulking portion (main body side cylindrical member) 20 provided on one side surface of the case main body 2, and the lid member 3 is formed by assembling a lid-side caulking portion (lid-side cylindrical member) 30 provided on one side surface, and a main-body-side caulking portion (main-body-side cylindrical member) 20 and a lid-side caulking portion (lid-side cylindrical member). 30 and the caulking portion (substrate case tubular member) 10 into which the insertion member 50 is inserted, and a substantially box-like shape with one surface opened. The opened surfaces are formed on the case body 2 and the lid member 3. A caulking portion cover (substrate case tubular member cover) that is locked to the case body 2 and the lid member 3 in a state in which the caulking portion (substrate case tubular member) 10 is accommodated in the posture toward the one side surface. ) 5 and a caulking part cover The (board case cylindrical member cover) 5 includes an inner locking piece (locking portion) 82 protruding from the case body 2 or the lid member 3 into the caulking portion cover (substrate case cylindrical member cover) 5; Locking that is locked inside the caulking portion cover (substrate case cylindrical member cover) 5 and that is a side surface facing the inner locking piece (locking portion) 82 in the caulking portion cover (substrate case cylindrical member cover) 5. The right side plate of the locking piece insertion body 70 is penetrated through the right side plate of the locking piece insertion body 70 at both side positions sandwiching the locking piece covering portion 73, which is a portion facing the inner locking piece (locking portion) 82. A pair of front and rear through-holes 75 are formed.

With such a configuration, the caulking part cover 5 attached to the substrate case 1 is viewed, and whether or not the caulking part cover 5 has been removed from the substrate case 1 before, that is, the caulking part and the caulking part It is possible to easily confirm whether or not the engagement with the cover 5 has been released.
Specifically, the inner locking piece 82 is covered with the locking piece covering portion 73 of the locking piece insertion body 70 in a state where the inner locking piece 82 is inserted (locked) into the locking piece insertion body 70 of the caulking portion cover 5. Has been. Accordingly, the inner locking piece 82 is configured not to be urged to the right side, that is, in a direction away from the locking piece receiving portion 79 locked in the locking piece insertion body 70. Yes. Therefore, in order to release the engagement between the board case 1 and the caulking portion cover 5 in the inner locking piece 82, after cutting and removing the locking piece covering portion 73 in the locking piece insertion body 70, It is necessary to cut the inner locking piece 82.
Thus, even when the caulking portion cover 5 is attached to the substrate case 1, the locking piece covering portion 73 in the locking piece insertion body 70 of the caulking portion cover 5 is visually recognized, for example, If the piece covering portion 73 is cut, it can be confirmed from the cut mark 73 a that the caulking portion cover 5 is once removed from the substrate case 1 and temporarily attached by the outer locking piece 81. If the engagement piece covering portion 73 is not cut, it can be confirmed that the caulking portion cover 5 has not been removed from the substrate case 1 yet. That is, a person in charge such as a game hall where the gaming machine is arranged can easily visually confirm that the caulking portion cover 5 has been removed from the substrate case 1.

  In the substrate case 1, the pair of front and rear through holes 75 are preferably formed at the ends of the caulking portion cover (substrate case cylindrical member cover) 5 on the case body 2 side and the lid member 3 side.

  With such a configuration, the pair of front and rear through-holes 75 are disposed at positions separated from the claw portion 84 of the inner locking piece 82 and the locking piece receiving portion 79 of the locking piece insert 70. The claw portion 84 and the locking piece receiving portion 79 are locked with each other using the through hole 75 (without cutting the locking piece covering portion 73 in the inner locking piece 82 and the locking piece insertion body 70). To prevent as much as possible fraudulent acts to be canceled, for example, fraudulent attempts to release the locking between the claw portion 84 and the locking piece receiving portion 79 by inserting a member such as a wire from a pair of front and rear through holes 75 Can do.

  In the substrate case 1, the pair of front and rear through holes 75 are provided on at least two or more side plates (side surfaces) of the caulking portion cover (substrate case cylindrical member cover) 5. It is desirable to provide inner locking pieces (locking portions) 82 corresponding to the through holes 75 respectively.

  With such a configuration, when the locking of the caulking portion cover 5 and the substrate case 1 is released and the locking piece covering portion 73 of the locking piece insert 70 is cut, the caulking portion cover 5 is engaged with the engagement portion cover 5. What is necessary is just to confirm it seeing from one side plate among the several side plates in which the stop piece insertion body 70 was provided. Therefore, for example, when the locking piece insert 70 is provided only on one side plate of the caulking portion cover, and it is checked whether or not the locking piece covering portion 73 in the locking piece insertion body 70 is cut by searching for this one side plate. The person in charge can quickly and efficiently confirm that the caulking portion cover 5 is once removed from the substrate case 1 and temporarily attached by the outer locking piece 81.
