  The control board 34 is housed in the housing space of the board box 30 with the mounting surface 34 a on which the one-chip microcomputer 27 and other electronic components 37 are mounted facing the lid member 33.

  The one-chip microcomputer 27 includes a ROM (read only memory) as a storage means that stores a game control program for performing game control, a CPU (central processing unit) that performs control based on the game control program, and control execution of the CPU A RAM (read-write memory) that stores necessary information as needed is integrated.

  As shown in FIG. 6, the mounting base 32, the lid member 33, and the control board 34 are first assembled to the lid member 33, and then the integrated lid member 33 and control board 34 are assembled. As shown in FIG. 3, this is performed by attaching to the attachment base 32.

  Attachment of the lid member 33 to the attachment base 32 is performed by fastening a fastening portion provided on the lid member 33 to a fastened portion provided on the attachment base 32.

  The fastening portion provided on the lid member 33 is a plurality of protrusions 35 disposed on the upper wall and the lower wall facing each other in the peripheral wall 33b. The fastened portions provided on the mounting base 32 are a plurality of storage portions 36 that are disposed at positions corresponding to the protrusions 35 on the peripheral wall 32 b and can store the protrusions 35.

  In attaching the lid member 33 to the attachment base 32, first, the lid member 33 is moved toward the attachment base 32 with the peripheral walls 32 b and 33 b facing each other, and the projection 35 of the lid member 33 is moved to the attachment base 32. It inserts in the accommodating part 36 from the opening part 36a.

  Next, the projection 35 is accommodated in the accommodation portion 36 by sliding the lid member 33 with respect to the mounting base 32 in a state where the projection 35 is inserted into the accommodation portion 36. As a result, the attachment base 32 and the lid member 33 are restricted from moving in directions away from each other. In this manner, the lid member 33 is attached to the attachment base 32, and the substrate box 30 is closed.

  However, the substrate box 30 can be opened by sliding the lid member 33 with respect to the attachment base 32 only by attaching the lid member 33 to the attachment base 32 via the protrusions 35 and the accommodating portion 36.

  Therefore, the substrate box 30 is provided with a sealing mechanism 31 that attaches the lid member 33 to the attachment base 32 and seals the substrate box 30 in a closed state.

  As shown in FIGS. 3 to 6, the sealing mechanism 31 includes a plurality of first sealing portions 41 connected to the side walls of the peripheral wall 32 b of the mounting base 32 via the connecting portions 40, and the lid member 33. A plurality of second sealing portions 43 connected to the side wall of the peripheral wall 33b via the connecting portion 42, and a one-way screw 50 for fixing the first sealing portion 41 and the second sealing portion 43 to each other. Prepare. In the present embodiment, four first sealing portions 41 and four second sealing portions 43 are formed. Hereinafter, when the four first sealing portions 41A to 41D and the four second sealing portions 43A to 43D are collectively referred to as the first sealing portion 41 and the second sealing portion 43, respectively.

  The first sealing portions 41 </ b> A to 41 </ b> D and the second sealing portions 43 </ b> A to 43 </ b> D are arranged side by side with a predetermined interval, and the lid member 33 is attached to the attachment base 32 via the protrusion 35 and the accommodation portion 36. The first sealing portions 41A to 41D and the second sealing portions 43A to 43D are disposed so as to contact each other. Note that the adjacent first sealing portions 41 </ b> A to 41 </ b> D are connected via the coupling portion 45.

  The first sealing portion 41 is formed in a substantially bottomed cylindrical shape, and a concave portion 41 a having an opening on the contact surface with the second sealing portion 43 is formed. The second sealing portion 43 is formed in a substantially cylindrical shape, and a through-hole 43a having an opening is formed on both the contact surface with the first sealing portion 41 and the opposite surface.

  The concave portion 41 a of the first sealing portion 41 and the through hole 43 a of the second sealing portion 43 are formed so as to communicate with each other in a state where the lid member 33 is attached to the attachment base 32. The one-way screw 50 is fastened across the recessed portion 41 a and the through hole 43 a to fix the first sealing portion 41 and the second sealing portion 43.

  In FIG. 3, only the pair of the first sealing portion 41A and the second sealing portion 43A is fixed by the one-way screw 50, and the top portion 50a of the one-way screw 50 is accommodated in the through hole 43a. . The other pair is a temporarily fixed state in which the one-way screw 50 is fastened only to the through-hole 43a, and the top 50a of the one-way screw 50 protrudes from the through-hole 43a.

  The one-way screw 50 is a screw that can only be turned in the tightening direction, and cannot be loosened after being fastened over the recess 41a and the through hole 43a. Therefore, in order to release the fixing of the first sealing portion 41 and the second sealing portion 43 fixed by the one-way screw 50, the first sealing portion 41 and the second sealing portion 43 are respectively attached to the mounting base 32 and the lid. This is done by separating from the member 33.

  As shown in FIGS. 5 and 7, the inner surface of the lid member 33, that is, the surface facing the control board 34 in the bottom 33 a, the control board 34 is stored in the board box 30, and the one-chip microcomputer 27 A surrounding member 51 surrounding the periphery is disposed.

  The surrounding member 51 has a peripheral wall 52 having a rectangular cross-section standing from the inner surface of the lid member 33, and an opening 51 a into which the one-chip microcomputer 27 can enter is opened on the side facing the control board 34. .

  The height of the peripheral wall 52 of the surrounding member 51 is set such that the tip 52b of the peripheral wall 52 is in contact with or close to the mounting surface 34a of the control board 34 with the lid member 33 closed with respect to the mounting base 32. ing. The surrounding member 51 is made of a transparent synthetic resin, like the mounting base 32 and the lid member 33, so that the internal one-chip microcomputer 27 can be seen through.

  When the lid member 33 having the surrounding member 51 configured as described above is attached to the attachment base 32, the one-chip microcomputer 27 mounted on the control board 34 is surrounded by the surrounding member 51. Therefore, even if a fraudulent person inserts a fraudulent tool such as a screwdriver or a thousand pieces into the board box 30 through the joint between the mounting base 32 and the lid member 33, the leading edge of the fraudulent tool is advanced by the surrounding member 51. Is prevented and does not reach the one-chip microcomputer 27. Even if the one-chip microcomputer 27 can be removed from the control board 34, the distance between the tip 52b of the peripheral wall 52 and the mounting surface 34a of the control board 34 is very small. Cannot be taken out of the surrounding member 51.

  A part of the peripheral wall 52 of the surrounding member 51 is formed so as to protrude from the distal end portion 52 b, and is configured as an insertion portion 53 through which a through hole 47 formed in the control board 34 is inserted.

  The insertion part 53 is formed in each of two opposing walls in the peripheral wall 52. As described above, the surrounding member 51 has the two insertion portions 53, and the control board 34 is formed with two through holes 47 through which the respective insertion portions 53 are inserted.

  As shown in FIG. 7, the tip of the insertion portion 53 protrudes outward in the vertical direction with respect to the insertion portion 53, and is hook-shaped that is locked to the edge portion 47 b of the through hole 47 of the control board 34. A locking portion 54 is provided. The through hole 47 of the control board 34 opens to a size that allows the locking portion 54 to be inserted.

  As shown in FIG. 5, slits 52 c extending from the distal end portion 52 b toward the proximal end portion are formed on both sides of the insertion portion 53 in the peripheral wall 52. By forming the slits 52 c on both sides of the insertion part 53, the insertion part 53 can be bent with the locking part 54 side as a free end and the base end side as a fulcrum. Thus, the insertion part 53 has flexibility.

  As shown in FIG. 7, the locking portion 54 is configured so that the through-hole 47 cannot be inserted unless the insertion portion 53 is bent in a direction approaching each other.

  The distal end of the locking portion 54 is configured as an inclined portion 54a formed in an inclined shape. When assembling the control board 34 to the lid member 33, the control board 34 and the lid member 33 are moved in a direction in which the control board 34 and the lid member 33 approach each other. It contacts the part 47a. When the control board 34 and the lid member 33 are brought closer to each other from this state, the inclined portion 54a moves forward along the edge portion 47a of the through hole 47, whereby the two insertion portions 53 have their free ends with the base end side as a fulcrum. The locking part 54 is guided in the through hole 47 by bending in the direction approaching each other. Then, by further bringing the control board 34 and the lid member 33 closer, the locking portion 54 passes through the through hole 47 and the insertion portion 53 returns to the original shape (state shown in FIG. 7).

  In a state where the locking portion 54 shown in FIG. 7 is inserted through the through hole 47, the back surface 54 b of the locking portion 54 is in contact with the edge portion 47 b of the through hole 47 on the surface 34 b opposite to the mounting surface 34 a of the control board 34. It will be in a state of confrontation. Since the back surface 54b is formed perpendicular to the insertion portion 53, when the control board 34 is moved away from the lid member 33, the back face 54b comes into contact with the edge 47b of the through-hole 47 and exceeds that of the control board 34. Regulate the movement of Thus, the back surface 54 b of the locking portion 54 functions as a stopper that prevents the control board 34 from coming off in a state where the control board 34 is assembled to the lid member 33.

  As shown in FIGS. 4 and 7, a contact portion 60 with which the tip 53 a of the insertion portion 53 contacts is disposed on the inner surface of the mounting base 32, that is, the surface facing the control board 34 in the bottom portion 32 a. FIG. 7 is a view showing a state immediately before the lid member 33 is attached to the attachment base 32.

  The contact portion 60 is formed so as to be inclined so that the insertion portions 53 bend in a direction away from each other when the distal end 53a of the insertion portion 53 contacts.

  When the lid member 33 is assembled to the mounting base 32 from the state shown in FIG. 7, the tip 53 a of the insertion portion 53 comes into contact with the contact portion 60 and the insertion portion 53 is inclined by the contact portion 60. Bend in the direction away from each other.

  Accordingly, the insertion portion 53 is pressed against the inner peripheral surface 47 c of the through hole 47, and the locking portion 54 is deeply locked with respect to the edge portion 47 b of the through hole 47. That is, the area where the back surface 54b of the locking portion 54 and the edge portion 47b of the through hole 47 face each other is increased. Therefore, the locking state between the locking portion 54 and the edge portion 47b of the through hole 47 becomes stronger. As described above, the contact portion 60 bends the insertion portion 53 in a direction in which the locking portion 54 is deeply locked with respect to the edge portion 47 b of the through hole 47.

  By bending the insertion portion 53, the locking state between the locking portion 54 and the edge portion 47b of the through hole 47 is strengthened. However, since the slit 52c is formed in the surrounding member 51 in order to give the insertion portion 53 flexibility, there is a possibility that an unauthorized tool is inserted into the surrounding member 51 through the slit 52c.

  As a countermeasure against this, as shown in FIGS. 4 and 8, a blocking member 61 that inserts the through hole 47 of the control board 34 and closes the slit 52 c formed in the surrounding member 51 is arranged on the inner surface of the mounting base 32. Established.

  Since the slit 52c of the surrounding member 51 is closed by the closing member 61 in a state where the lid member 33 is attached to the mounting base 32, an illegal act of inserting an unauthorized tool into the surrounding member 51 is prevented.

  Further, as shown in FIG. 8, a step portion 61 a is formed in the closing member 61. The peripheral wall 52 of the surrounding member 51 is formed with a support portion 52d that engages with the step portion 61a and supports the closing member 61 when the closing member 61 is pressed from the outside.

  Therefore, even when the blocking member 61 is pressed by an unauthorized tool, the blocking member 61 is not deformed, and the unauthorized act of inserting the unauthorized tool into the surrounding member 51 is more reliably prevented.

  Further, it is desirable that the closing member 61 is formed integrally with the contact portion 60. Thus, since the intensity | strength of the closure member 61 increases by comprising, the deformation | transformation of the closure member 61 when the closure member 61 is pressed by an unauthorized tool is prevented more reliably.

  Below, the assembly method of the board | substrate box 30 is demonstrated.

  First, as shown in FIG. 5, the mounting surface 34 a of the control board 34 and the inner surface of the lid member 33 are opposed to each other, and pins 33 d disposed diagonally to the lid member 33 are formed diagonally to the control board 34. The control board 34 and the lid member 33 are brought closer to each other so as to be inserted into the positioning hole 34c.

  In the process of bringing the lid member 33 and the control board 34 close to each other, the one-chip microcomputer 27 enters the inside of the surrounding member 51, and the engaging part 54 of the insertion part 53 is an edge part of the through hole 47 of the control board 34. 47a abuts.

  When the lid member 33 and the control board 34 are brought closer to each other, the two insertion portions 53 bend in a direction in which the locking portions 54 approach each other. The locking portion 54 is guided into the through hole 47 and inserted through the through hole 47. After the locking portion 54 is inserted through the through hole 47, the insertion portion 53 returns to its original shape (the state shown in FIGS. 6 and 7). As a result, the locking portion 54 is locked to the edge portion 47 b of the through hole 47, and the control board 34 is assembled to the lid member 33.

  Next, the integrated lid member 33 and control board 34 are attached to the attachment base 32. The attachment of the lid member 33 to the attachment base 32 is performed by accommodating the protrusion 35 of the lid member 33 in the accommodation portion 36 of the attachment base 32 as described above.

  In this process, the distal end 53a of the insertion portion 53 comes into contact with the contact portion 60, so that the insertion portion 53 bends away from each other. Accordingly, the insertion portion 53 is pressed against the inner peripheral surface 47 c of the through hole 47, and the locking portion 54 is deeply locked with respect to the edge portion 47 b of the through hole 47, and the locking portion 54 and the through hole 47 are The edge 47b is firmly locked. At the same time, the slit 52 c of the surrounding member 51 is closed by the closing member 61.

  As described above, by attaching the attachment base 32 and the lid member 33, the one-chip microcomputer 27 is surrounded by the surrounding member 51 and the control board 34 is locked to the lid member 33.

  After attaching the attachment base 32 and the lid member 33, one pair (in FIG. 3, the first sealing portion 41 </ b> A and the second sealing portion among the first sealing portion 41 and the second sealing portion 43). The pair of stop portions 43 </ b> A) is fixed by the one-way screw 50, and the substrate box 30 is sealed.

  When the one-chip microcomputer 27 mounted on the control board 34 housed in the board box 30 is inspected by a public institution, the first sealing part 41A and the second sealing part 43A that are fixed are connected. The first sealing portion 41A and the second sealing portion 43A are removed by cutting the portions 40, 42 and the connecting portion 45 of the first sealing portion 41A and the first sealing portion 41B with a nipper or the like. In this way, the board box 30 is normally opened.

  After the inspection by the public organization, the temporarily sealed first sealing portion 41B and second sealing portion 43B are fixed by the one-way screw 50, and the substrate box 30 is sealed again.

  According to the embodiment described above, the following effects can be obtained.

  Even when the sealing mechanism 31 is broken and the substrate box 30 is opened, the engaging portion 54 at the distal end of the insertion portion 53 of the surrounding member 51 disposed on the lid member 33 is the edge of the through hole 47 of the control substrate 34. Since it is locked to the portion 47b, the control board 34 is locked to the lid member 33, and the one-chip microcomputer 27 is prevented from being exposed. In this way, the board box 30 is difficult to cheat.

  Further, when the control board 34 is assembled to the lid member 33, the locking part 54 passes through the through hole 47 of the control board 34 due to the insertion part 53 being bent. Then, after the locking portion 54 has been inserted through the through hole 47, the locking portion 54 is locked to the edge portion 47 b of the through hole 47 of the control board 34 by returning the insertion portion 53. Thus, since the locking portion 54 cannot be inserted through the through hole 47 of the control board 34 unless the insertion portion 53 is bent, the locking portion 54 is reliably locked with the edge 47b of the through hole 47, and the lid The member 33 and the control board 34 are prevented from coming off.

  Further, since the insertion portion 53 is bent and pressed against the inner peripheral surface 47 c of the through hole 47 by the tip 53 a of the insertion portion 53 coming into contact with the contact portion 60, the locking portion 54 is an edge portion of the through hole 47. It is deeply locked to 47b. Therefore, the locking state between the locking portion 54 and the edge portion 47b of the through hole 47 becomes stronger.

  Furthermore, since the slit 52c of the surrounding member 51 is closed by the closing member 61, an unauthorized act of inserting an unauthorized tool into the surrounding member 51 is prevented.

  The present invention is not limited to the above-described embodiment, and it is obvious that various modifications can be made within the scope of the technical idea.

  The gaming machine of the present invention is not limited to the pachinko gaming machine as shown in the above embodiment, and uses, for example, gaming balls such as other pachinko gaming machines, arrange ball gaming machines, and sparrow ball gaming machines. Applicable to all gaming machines.
