By inserting and engaging the third restricting piece 138b formed on the rear mounting piece 138, the display control board 75 is positioned at a position separated from the installation plate 110 (see FIG. 16). Then, the display control board 75 is inserted into the screw holes 137a and 138a of the corresponding rear mounting pieces 137 and 138 by inserting the screws SC inserted into the through holes 75a of the display control board 75 into the display data board. 76 and the inverter relay board 77 are fixed so as to be spaced apart and partially overlap each other (see FIG. 16). In addition, by positioning the display control board 75 at the rear ends of the rear mounting pieces 137 and 138, the insertion terminals 141 protruding from the non-mounting surface of the display control board 75 are inserted into the display data board 76. Inserted into the receiving portion 144, the two substrates 75 and 76 are electrically connected. Further, the other end of the cable having one end connected to the liquid crystal relay board 78 before the display data board 76 is attached to the metal plate 82 is connected to the display control board 75 after the display data board 76 and the display control board 75 are attached. As a result, the display control board 75 and the liquid crystal relay board 78 are electrically connected. Further, by connecting the display control board 75 and the inverter relay board 77 by connectors, all the boards 75, 76, 77, 78 disposed on the metal plate member 82 are electrically connected in a predetermined relationship. .

  As described above, the plurality of substrates 75, 76, 77, 78 are fixed to the metal plate member 82 via the corresponding first to third fixing portions 126, 127, 128, so that they are all or partly in the front-rear direction. Will overlap. That is, by arranging a plurality of substrates 75, 76, 77, 78 in the front-rear direction, the installation space for the substrates 75, 76, 77, 78 can be reduced, and the display control device 52 can be made compact. obtain. Further, by sequentially fixing the plurality of substrates 75, 76, 77, 78 via the first to third fixing portions 126, 127, 128, the control ROM 139, the CPU 140, and the data ROM 143 mounted on each mounting surface. The substrates 75, 76, 77, 78 can be fixed in such a positional relationship that various electronic components such as other electronic components 147 do not contact each other.

(Installation of metal plate)
The attachment of the metal plate 82 to the base member 80 in the display control device 52 will be described. The elastic body 117 is attached to each of the three first mounting portions 115 and one second mounting portion 116 formed on the metal plate member 82 to which the plurality of substrates 75, 76, 77, 78 are fixed. That is, by pushing the small-diameter fitting portion 117b of the elastic body 117 into the housing portion 119 from the inlet portion 118 of each mounting portion 115, 116, the installation plate 110 of the metal plate member 82 is moved to the first holding portion as shown in FIG. The elastic body 117 is attached to the metal plate member 82 while being sandwiched between the second holding portion 124 and the second holding portion 124. In this case, since the opening size of the inlet portion 118 in each of the mounting portions 115 and 116 is set to be smaller than the diameter of the small diameter fitting portion 117b of the elastic body 117, the elastic body 117 attached to each of the mounting portions 115 and 116. However, the elastic body 117 is not dropped during the operation of attaching the metal plate 82 to the base member 80, and the operation is interrupted, so that the operation can be performed smoothly. .

  The metal plate member 82 to which the four elastic bodies 117 are attached is projected from the front wall 83 to the through-hole 117c of each elastic body 117 so that the installation plate 110 faces the front wall 83 of the base member 80. Temporarily attached so that the corresponding arrangement boss 88 is inserted. In this case, the second mounting portion 116 for a mark provided on the metal plate member 82 is non-linear with respect to a line segment passing through the center point of the metal plate member 82 (installation plate 110) with respect to the other first mounting portions 115. Because of the symmetrical relationship, when the mounting direction of the metal plate 82 is different with respect to the base member 80, the arrangement boss 88 is inserted into the through hole 117c of the elastic body 117 attached to the second mounting portion 116. Thus, it can be reliably determined that the mounting direction of the metal plate member 82 is wrong.

  Screws of the flanged screws 125 from the first holding part 123 side to the screw holes 88a of the disposing bosses 88 inserted through the through holes 117c of the respective elastic bodies 117 of the metal plate member 82 temporarily attached to the base member 80. The part 125b is screwed. As a result, the metal plate member 82 to which the plurality of substrates 75, 76, 77, 78 are fixed is provided on each side portion provided on the edge of the installation plate 110 as shown in FIG. 16, FIG. 17, FIG. 111, 112, 113, 114 are attached at appropriate positions where they do not contact the corresponding walls 84, 85, 86, 87 of the base member 80.

(Assembling the first case body)
The corresponding engagement holes 92a of the cover member 81 are respectively inserted into the engagement pieces 86a of the base member 80 to which the metal plate material 82 to which the plurality of substrates 75, 76, 77, 78 are fixed is attached. Originally, by bringing the cover member 81 close to the base member 80, the locking claw 87 a of the base member 80 is locked in the locking hole 93 b of the cover member 81, and the cover member 81 is fixed to the base member 80. The first case body 79 is configured by being attached (see FIG. 15). That is, the metal plate member 82 and the plurality of substrates 75, 76, 77, 78 are accommodated in the first case body 79. At this time, as shown in FIG. 16 or FIG. 17, the metal plate member 82 has side walls 111, 112, 113, 114 provided on the edge of the installation plate 110 corresponding to the walls 90, 91, 114 corresponding to the cover member 81. It is accommodated in a state where it is not in contact with 92,93.

(Countermeasures against substrate vibration)
When the metal plate 82 is attached to the base member 80, the first protrusion 123a of the elastic body 117 contacts the support portion 125a of the flanged screw 125 as shown in FIG. The second protrusion 124a of the elastic body 117 is in contact with the wall 83), and the metal plate member 82 is not in direct contact with the base member 80. As described above, the side walls 111, 112, 113, 114 provided on the edge of the installation plate 110 of the metal plate member 82 also correspond to the corresponding walls 84, 85, 86, 87 and the cover member 81 of the base member 80. Are not in contact with any of the corresponding walls 90, 91, 92, 93. That is, the metal plate 82 is in contact only with the elastic body 117, and vibrations from the base member 80 and the cover member 81 are suppressed from being attenuated by the elastic body 117 and vibrating the metal plate 82. Moreover, since only the protrusions 123a and 124a of the elastic body 117 are in contact with the support portion 125a and the base member 80, and the contact area of the elastic body 117 with respect to the support portion 125a and the base member 80 is small, the base member 80 and the cover member The absorption rate by the elastic body 117 of the vibration transmitted from the 81 and the flanged screw 125 is increased, and the vibration transmitted to the metal plate member 82 can be further reduced.

  Further, in the flanged screw 125 in which the screw portion 125 b is screwed into the screw hole 88 a of the arrangement boss 88 of the base member 80, the support portion 125 a comes into contact with the rear end of the arrangement boss 88 as shown in FIG. 22. Thus, the position is regulated, and the distance between the support portion 125a and the front wall 83 of the base member 80 is kept constant. That is, the tightening amount of the flanged screw 125 is not changed by an operator, and the protrusions 123a and 124a of the elastic body 117 are prevented from being excessively crushed, thereby supporting the support portion 125a and the base member of the elastic body 117. The contact pressure for 80 can always be constant. Thereby, the vibration absorption capability by the elastic body 117 is always constant, and the vibration transmitted to the metal plate member 82 can be suitably reduced. In addition, the disposition boss 88, which is a means for attaching the metal plate member 82 to the base member 80, has a function of keeping the distance between the support portion 125a and the base member 80 constant. There is no need, the number of parts can be reduced, and the mounting work of the metal plate 82 to the base member 80 is simplified.

  As described above, the metal plate member 82 to which the plurality of substrates 75, 76, 77, 78 constituting the display control device 52 is fixed is elastic with respect to the base member 80 and the cover member 81 (first case body 79). Since the contact is made only through the body 117, the pachinko machine 10 and the game board 33 are transported in the state in which the symbol display device 13 having the display control device 52 attached thereto is disposed on the game board 33 as described later. The elastic body 117 can suppress the vibration generated in the symbol display device 13 when the middle frame 12 is opened and closed with respect to the outer frame 11 from being transmitted to the plurality of substrates 75, 76, 77, 78 constituting the display control device 52. That is, in particular, since it is possible to suppress the occurrence of poor contact of the control ROM 139 and CPU 140 mounted on the display control board 75 and the data ROM 143 mounted on the display data board 76, the effects on the symbol display device 13 can be suppressed. In this way, it is possible to prevent the player from being disadvantaged or confused. In addition, since the metal plate 82 to which the plurality of substrates 75, 76, 77, and 78 are fixed and the base member 80 are attached via the elastic body 117, vibration countermeasures are provided for each of the substrates 75, 76, 77, and 78 ( There is no need to apply the elastic body 117), and the number of elastic bodies 117 used can be reduced to reduce the cost. As a mounting portion for attaching the elastic body 117 to the metal plate member 82, a second portion provided at a position that is largely separated from the edge of the installation plate 110 through a hole 121 formed in the installation plate 110. By adopting the mounting portion 116, it is possible to perform vibration isolation at an intermediate position of the metal plate member 82 (a position between the upper and lower or left and right edges of the installation plate 110). That is, since the metal plate material 82 can be supported by the elastic body 117 not only at the four corners of the installation plate 110 but also at an intermediate position, vibration due to the bending of the metal plate material 82 (installation plate 110) can also be suppressed.

(Attaching the display control device to the symbol display device)
As described above, the display control device 52 in which the substrates 75, 76, 77, and 78 are accommodated in the first case body 79 is provided with the first insertion piece 86 b formed in the base member 80 in the symbol display device 13. The first receiving portions 51b are inserted and engaged, and the first connecting portions 96 formed on the cover member 81 are aligned with the corresponding first connected portions 51c provided on the symbol display device 13, respectively. In this state, the display control device 52 is attached to the symbol display device 13 by connecting the first connecting portion 96 and the first connected portion 51c with the first connecting device 97 (see FIG. 5). Since the metal plate member 82 is disposed to face the base member 80 located on the symbol display device 13 side in the display control device 52, various substrates 75 disposed on the metal plate member 82 are affected by electrical noise. , 76, 77, 78 can be prevented from reaching various electronic components.

(Attaching the integrated drive unit to the display controller)
The overall drive device 104 is engaged by inserting the second insertion piece 106 a formed in the third case body 106 into the second receiving portion 98 a provided in the installation portion 98 of the cover member 81 in the display control device 52. At the same time, the second connecting portion 106 b formed in the third case body 106 is aligned with the second connected portion 98 b provided in the installation portion 98 of the cover member 81 of the display control device 52. In this state, by connecting the second connecting portion 106b and the second connected portion 98b with the second connecting tool 107, the overall driving device 104 is attached to the installation portion 98 of the display control device 52 in an overlapping state (FIG. 5).

  The inverter board 53 is screwed to the right of the display control device 52 on the back surface of the symbol display device 13 and the inverter cover 101 is placed on the back surface of the symbol display device 13 so as to cover the inverter substrate 53. Install. A plurality of control devices are attached to the back surface of the symbol display device 13 by attaching the overall control device 54 to the back surface of the inverter cover 101.

(Protection of electronic components in display control devices)
In the overall drive device 104 attached to the back surface of the display control device 52, the relay socket 109 provided on the overall drive substrate 105 is connected to the lower relay substrate 74 disposed on the game board 33. The wiring plug is plugged in from behind. At this time, a force for inserting the plug into the relay socket 109 is applied to the cover member 81 in which the overall driving device 104 is disposed in a direction in which the cover member 81 is bent forward. However, as shown in FIG. 18, a plurality of first ribs 99 are arranged vertically and horizontally on the inner surface of the cover member 81 to enhance rigidity, so that the plug is connected to the relay socket 109 of the overall drive board 104. Even when force is applied to the cover member 81, the cover member 81 (rear wall 89) can be prevented from being greatly bent. In addition, the inner surface of the cover member 81 has a large projecting dimension over the entire length in the vertical direction at a position corresponding to the relay socket 109 of the overall drive board 105 in the overall drive device 104 attached to the installation portion 98. Since the two ribs 100 are formed, the occurrence of bending due to the force applied when the plug is inserted into the relay socket 109 of the overall drive board 104 can be further suppressed. That is, the rear wall 89 of the cover member 81 is bent inward and can be prevented from coming into contact with various electronic components such as the control ROM 139 and CPU 140 mounted on the display control board 75.

  Note that the second rib 100 having a large protruding dimension is formed by using a step portion generated by disposing the display control board 75 and the display data board 76 in the first case body 79 apart from each other in the front-rear direction. Since it is formed, the projecting dimension of the second rib 100 can be increased without increasing the depth dimension (front-rear dimension) of the cover member 81 (see FIGS. 16 and 17). That is, it is not necessary to increase the depth dimension of the cover member 81 in order to increase the projecting dimension of the second rib 100, and the longitudinal dimension of the first case body 79 (display control device 52) while increasing the rigidity of the cover member 81. Can be reduced.

  In addition, since a plurality of protrusions 89b projecting larger than the first rib 99 are provided on the inner surface of the cover member 81, the force applied when the plug is inserted into the relay socket 109 of the overall drive board 105. Even if the rear wall 89 is trapped by the above, the protrusion 89b is formed on the mounting surface of the display control board 75 before the first rib 99 comes into contact with various electronic components such as the control ROM 139 and CPU 140 of the display control board 75. Can abut and regulate bending. Therefore, it is possible to reliably prevent the first rib 99 from coming into contact with various electronic components such as the control ROM 139 and the CPU 140, and to prevent the occurrence of failure of these electronic components. That is, the display is performed without taking into account the position of various electronic components such as the control ROM 139 and CPU 140 mounted on the display control board 75 of the display control device 52 and the position of the relay socket 109 of the overall drive board 105. The overall drive device 104 can be placed on the rear side of the control device 52 in an overlapping manner. As described above, since the position of the overall drive device 104 is not limited, the degree of freedom in design is increased, and a space in which another control device cannot be installed on the rear side of the display control device 52 does not occur. Can be used effectively.

  Further, the first rib 99, the second rib 100, and the protrusion 89b provided on the cover member 81 of the display control device 52 are in the normal state in which no load is applied to the rear wall 89 of the cover member 81. Since it does not come into contact with the control board 75, vibrations are not transmitted to the display control board 75 via the ribs 99, 100 and the protrusion 89b (see FIGS. 16 and 17). That is, while the rigidity of the cover member 81 is improved by the ribs 99, 100 and the protrusions 89b, the failure of various electronic components such as the control ROM 139 and the CPU 140 mounted on the display control board 75 is prevented. It is possible to prevent vibration from being transmitted from the cover member 81 to the display control board 75 and to suppress the occurrence of defects due to the vibration of the various electronic components.

  Note that a support piece 114a for supporting the display control board 75 from the front side is provided at a position close to the socket 142 provided on the display control board 75 in the metal plate member 82 (see FIGS. 16 and 20). When the plug of the wiring to be connected to the lower relay board 74 is inserted into the socket 142 from the rear side, the display control board 75 is restrained from being bent and is mounted on the inverter relay board 77 arranged to overlap the front side. It is possible to prevent the display control board 75 from coming into contact with the electronic components that are present and causing a failure.

(Removal of the symbol display device from the game board)
Next, fixing the symbol display device 13 to the game board 33 (back unit 36) will be described. With the symbol display device 13 in an oblique posture with respect to the installation surface 60 of the back unit 36, a pair of locking protrusions 51 a, 51 a formed on the left side surface of the symbol display device 13 is provided on the back unit 36. The symbol display device 13 is rotated so that the right side surface is close to the back unit 36 in this state. Then, the front surface (accommodating case 51) of the symbol display device 13 is brought into contact with the installation surface 60 of the back unit 36, and the upper and lower lock members 64, 64 are rotationally displaced from the release position to the locking position, The lock members 64, 64 are brought into contact with the corresponding receiving portions 55, 55 of the symbol display device 13, whereby the symbol display device 13 is fixedly held in the installation area S of the back unit 36 (see FIG. 5). At this time, the front surface of the symbol display device 13 abuts on the installation surface 60, and the rear surfaces (receiving portions 55, 55) of the symbol display device 13 abut on the upper and lower lock members 64, 64, The back and forth movement of the symbol display device 13 is restricted. Further, the right side surface of the symbol display device 13 abuts on the right side wall portion 59, and the left side surface of the symbol display device 13 contacts the abutment surface 61 a of the abutment guide piece 61 formed on the left side wall portion 58. By the contact, the right and left movement of the symbol display device 13 is restricted. Further, the upper surface of the symbol display device 13 is in contact with the upper wall portion 56 and the lower surface of the symbol display device 13 is in contact with the lower wall portion 57, whereby the symbol display device 13 is moved up and down. Be regulated.

  On the other hand, in order to remove the symbol display device 13 from the game board 33 (back unit 36), the upper and lower lock members 64, 64 are rotationally displaced from the locking position to the release position, and the upper and lower lock members 64, 64 are removed. Are separated from the corresponding receiving portions 55, 55 of the symbol display device 13, and in this state, the right side of the symbol display device 13 is rotated so as to move backward. The pair of locking projections 51a and 51a formed on the left side surface of the symbol display device 13 is extracted from the corresponding insertion ports 58a and 58a formed on the left side wall portion 58 of the back unit 36, thereby the symbol. The display device 13 is removed from the installation area S of the back unit 36. Thus, when the symbol display device 13 is attached to the game board 33 (back unit 36), the locking projections of the symbol display device 13 are inserted into the insertion ports 58a, 58a provided in the game board 33 (back unit 36). With the 51a and 51a inserted, it is only necessary to bring the housing case 51 of the symbol display device 13 into contact with the installation surface 60 and to rotationally displace the lock members 64 and 64 to the locking position. When removing the game board 33 from the game board 33 (back unit 36), it is only necessary to displace the locking members 64, 64 to the release position and to extract the locking projections 51a, 51a from the insertion ports 58a, 58a. Even the symbol display device 13 can be easily attached and detached.

(Operation of lock member)
When the lock member 64 at the release position is rotationally displaced toward the locking position in order to fix the symbol display device 13 having the front surface in contact with the installation surface 60 of the installation area S, it is provided on the contact surface portion 69. The restricting projection 73 is brought into contact with and locked to the locking recess 67 of the pedestal 62, and the lock member 64 is positioned at the locking position. Further, immediately before the lock member 64 reaches the locking position, the corner portion of the contact surface portion 69 abuts against the regulating piece 68 provided on the pedestal portion 62 and is subjected to a load applied when rotating while elastically deforming it. On the other hand, the load can be reduced by separating the corner from the restricting piece 68, so that the operator can determine that the lock member 64 has reached the locking position. That is, the operator can grasp that the lock member 64 has reached the locking position, and can prevent the lock member 64 and the pedestal portion 62 from being damaged by turning the lock member 64 too much. Furthermore, since the lock member 64 of the embodiment is configured to be pivotably held via a fixing bracket 65 that is fixed to the pedestal portion 62 via two screws, the symbol display device 13 at the locking position. Therefore, the symbol display device 13 can be held in the installation area S over a long period of time. That is, even if vibration is generated by carrying the pachinko machine 10 or the game board 33 or opening / closing the middle frame 12 with respect to the outer frame 11, it is possible to suppress the movement of the symbol display device 13 in the front-rear direction as much as possible. In other words, the symbol display device 13 itself is less likely to vibrate. Therefore, vibrations of the display control device 52 and the overall control device 54 disposed on the back side of the symbol display device 13 are also suppressed, and each device 52 , 54 of the substrates 75, 76, 77, 78, 102, it is possible to suppress the occurrence of defects due to vibrations of various electronic components.

  Further, when the lock member 64 is rotationally displaced from the locking position to the release position, the rotation is restricted by the side edge of the abutment surface portion 69 abutting against the regulation piece 68 of the pedestal portion 52, The lock member 64 is positioned at the release position. That is, by restricting the rotation of the lock member 64, the operator can grasp that the lock member 64 has reached the release position.
