Further, on the left and right side portions of the substrate case 131, connection fixing portions (protruding portions) 135, 135 for connecting and fixing the dish-like member 131a and the cover-like member 131b are formed so as to protrude sideways. When the control device 130 is disposed on the upper surface side of the drum case 60, the rear side of the connection fixing portions 135, 135 abuts on the front side of the third position regulating pieces 121, 121 formed on the upper metal plate 111. It is configured to

(About the fixture)
The fixtures 140 and 140 are formed corresponding to the left and right second engaging protrusions 134 and 134 formed on the control device 130 (substrate case 131), respectively, and are positioned on the right side as shown in FIG. The fixing tool 140 corresponding to the second engaging protrusion 134 and the fixing tool 140 corresponding to the second engaging protrusion 134 located on the left side are formed in a symmetrical shape. As shown in FIG. 20, at the upper position of each of the fixtures 140, the upper restriction wall 141 and the side restriction walls 142, 142 are opened to the front and the side (side facing the other fixture 140). A mating recess 143 is formed, and the second engaging projection 134 corresponding to the engaging recess 143 can be inserted.

  The fixing tool 140 is formed with a through hole 144 penetrating in the front-rear direction at a position corresponding to the third screw hole 74 a of the screw boss 74 provided in the rear case body 62, and the engaging recess 143. In a state where the corresponding second engaging protrusion 134 is inserted into the second engaging protrusion 134, the screw inserted into the through hole 144 is screwed into the third screw hole 74a, whereby the second engaging protrusion 134 of the control device 130 is inserted. Are in contact with the upper restriction wall 141 and the side restriction walls 142, 142, respectively, and are fixed in a state where movement in the rear, upper and left and right directions is restricted. Further, on the surface of the fixture 140 facing the screwing boss 74, a support plate portion 73 on which the screwing boss 74 is formed and a groove portion 145 aligned with the reinforcing rib 73a are formed. By allowing the plate portion 73 and the reinforcing rib 73a to face the groove portion 145, the through hole 144 of the fixture 140 and the third screw hole 74a of the screwing boss 74 are aligned in the front-rear direction. Each of the fixtures 140 is formed with a wiring hook 146 so that a wiring (not shown) connecting the first connector receiving portion 26a and the third connector receiving portion 132 can be locked. It has become.

(Effects of Example)
Next, the operation of the drum-type symbol display device 20 according to the above-described embodiment will be described. Each symbol display unit 21 provided in the drum-type symbol display device 20 has a drive motor 31 disposed on a base metal plate 27 and the drive motor 31 is inserted into an opening 24 a provided in a printed wiring board 24. The support plate 23 of the symbol display unit 21 is configured by fixing the printed wiring board 24 and the base metal plate 27. Thus, by superimposing the base metal plate 27 on the printed wiring board 24, the rigidity of the symbol display unit 21 (support plate 23) can be dramatically increased. At this time, the second connector receiving portion 26b connected to the drive motor 31 and the LED 42 of the illuminating means 41 are surface-mounted on the printed wiring board 24, so that component leads are provided from the back surface of the printed wiring board 24. It does not protrude, and it is not necessary to provide a relief hole in the base metal plate 27 for escaping the component lead. Accordingly, the reinforcing effect of the printed wiring board 24 by the base sheet metal 27 is not reduced, and the labor required for processing the base sheet metal 27 can be omitted to reduce the cost. Then, by attaching the drive motor 31 to the base metal plate 27, the base metal plate 27 functions as a so-called heat sink, and the drive motor 31 can be prevented from overheating.

  The symbol display unit 21 inserts the rotating shaft 31a of the drive motor 31 into the through hole 35a formed in the fixing plate 35 of the symbol drum 34 in a state where the printed wiring board 24 and the base metal plate 27 are fixed. The design drum 34 is assembled to the drive motor 31 by inserting the positioning protrusion formed on the fixed plate 35 into the positioning hole 32 a formed in the disk-like member 32 of the drive motor 31. That is, positioning by the rotation shaft 31a of the drive motor 31 and the through hole 35a of the design drum 34 (fixed plate 35) and positioning hole 32a of the drive motor 31 (disk-shaped member 32) and the design drum 34 (fixed plate 35). By positioning by the projection 35b, the original position detection sensor built in the drive motor 31 and the symbol displayed on the symbol drum 34 can be assembled so as to always have a fixed positional relationship. Therefore, by controlling the drive motor 31 based on the detection by the original position detection sensor, each symbol displayed on the symbol drum 34 can be stopped at an arbitrary position.

  The symbol display unit 21 is configured such that a cover member 50 is disposed on the front end edge side of the support plate 23 (the printed wiring board 24 and the base metal plate 27), and the front end edge is covered with the cover member 50. Therefore, when the symbol display unit 21 is accommodated in the drum case 60, the front edge of the support plate 23 (the mating surface of the printed wiring board 24 and the base metal plate 27) cannot be seen from the player side. It is possible to prevent the appearance of the display device 20 from being damaged.

  Further, since the covering piece 55 formed on the cover member 50 extends to the front of the LED of the illumination means 41 and extends so as to face the inside of the design drum 34, the design drum 34 is emitted when the LED 42 emits light. It is possible to prevent light from leaking from between the support plate 23 and the printed wiring board 24. When the LED 42 emits light, the reflected light reflected by the reflecting surfaces 44a, 44b, 44c, and 44d of the reflector member 43 is irradiated on the pattern film 39 of the pattern drum 34, and the front side is irradiated. The incoming symbol is brightened. Thus, by illuminating the design of the design drum 34 only with the reflected light from the reflector member 43, the design can be illuminated with uniform brightness, and the occurrence of illumination spots can be prevented. .

  In order to attach the reflector member 43 and the cover member 50 to the support plate 23, the arc-shaped covering portion 51 of the cover member 50 is attached to the arc-shaped edge 25 of the support plate 23 (printed wiring board 24 and base metal plate 27). , 28 from the front side, and the protruding piece 51a formed on the cover member 50 is brought into contact with the surface of the printed wiring board 24 to position the cover member 50 with respect to the support plate 23. At this time, since the first insertion holes 24b and 24b of the printed wiring board 24 and the second insertion holes 54a and 54a of the contact piece 54 in the cover member 50 are aligned, the first and second insertion holes The reflector member 43 and the cover member 50 are positioned at a time with respect to the support plate 23 by inserting the boss portions 46 and 46 of the reflector member 43 into the respective 24b and 54a. At this time, each of the through holes 46a, 46a of the boss portions 46, 46 is aligned with the first screw holes 27a, 27a formed in the base metal plate 27, so that the screws inserted into the respective through holes 46a correspond to the corresponding ones. Screwed into the first screw hole 27a. At this time, since the contact pieces 54 and 54 of the cover member 50 are sandwiched between the attachment pieces 45 and 45 of the reflector member 43 and the printed wiring board 24, the reflector member 43 is attached to the base metal plate 27. By screwing, the three members of the reflector member 43, the cover member 50, and the printed wiring board 24 can be fixed at a time.

  In order to accommodate and hold each of the symbol display units 21 in the drum case 60, a portion where the printed wiring board 24 and the base metal plate 27 overlap at the rear upper and lower positions of the support plate 23 is formed in the rear case body 62. The difference between the pair of first insertion pieces 71a, 71a of the second rear side clamping part 71 formed on the rear case body 62, while being inserted between the pair of regulation protrusions 70a, 70a of the first rear side clamping part 70. Include. As a result, the rear side of the symbol display unit 21 is positioned and held. In this state, the front case body 76 is faced from the front of the symbol display unit 21, and a portion where the printed wiring board 24 and the base metal plate 27 overlap is formed in the front case body 76 at the lower position on the front side of the support plate 23. Between the pair of second insertion pieces 83a, 83a of the front clamping part 83 and between the pair of engagement pieces 56a, 56a of the insertion engagement part 56 formed at the upper end of the cover member 50, The protrusion 84 formed in the front case body 76 is inserted. Thereby, the front side of the symbol display unit 21 is positioned and held. At this time, the first inner stepped portion 81a formed in the front case body 76 contacts the front end portion of the support plate 23 (insertion engaging portion 56 of the cover member 50), and the second inner stepped portion 81b Since the front end of the support plate 23 abuts, the front movement of the symbol display unit 21 is restricted, and the symbol display unit 21 is held at a predetermined position in the drum case 60.

  Here, as described above, each of the first rear clamping unit 70, the second rear clamping unit 71, and the front clamping unit 83 has the support plate 23 at a portion where the printed wiring board 24 and the base metal plate 27 overlap. Therefore, the printed wiring board 24 can be prevented from being damaged due to vibration during transportation, and the printed wiring board 24 and the base sheet metal 27 can be prevented from being peeled and a gap between the members 24 and 27 can be prevented. obtain. Further, the relationship between the distance between the pair of engaging pieces 56a and 56a formed on the cover member 50 and the width of the protrusion 84 is such that the width of the protrusion 84 is slightly larger. When the protrusions 84 are inserted into a pair of engaging pieces 56a, 56a that are alternately formed on the front and rear sides, the protrusions 84 are formed by the engaging pieces 56a, 56a. The symbol display unit 21 can be firmly held in the drum case 60 by being pinched so as to be bitten. At this time, a tapered portion is formed at the rear end of the protruding portion 84 so as to taper rearward, and when the protruding portion 84 is inserted, the tapered portion is interposed between the engagement pieces 56a and 56a. The protrusion 84 can be easily inserted between the engagement pieces 56a and 56a.

  Thus, since the symbol display unit 21 is sandwiched between the front and rear case bodies 62 and 76, the vicinity of the four corners of the support plate 23 is supported, so that the stability of the symbol display unit 21 is improved. Since the transparent cover body 90 and the upper and lower metal plates 111 and 125 can be assembled in a state where the symbol display unit 21 is stable, the assembling work can be easily performed. Further, when the symbol display unit 21 is accommodated in the drum case 60, the second screw hole 29a of the fixing piece 29 formed in the base metal plate 27 in the support plate 23 is formed in the rear wall surface 64 of the rear case body 62. The insertion hole 64b is configured to be aligned in the front-rear direction. Therefore, a screw can be screwed into the second screw hole 29a of the fixing piece 29 formed on the base metal plate 27 from the outside of the drum case 60, and the backlash of the symbol display unit 21 housed in the drum case 60 is effective. Can be prevented.

  When attaching the metal frame member 110 to the drum case 60, first, the locking pieces 118, 118 of the second restricting portions 129 formed on the lower metal plate 125 are attached to the lower surface portion 93 of the transparent cover body 90. The extension piece 117 of the second restricting portion 129 is made to be a hook-shaped recess in a state of being positioned in front of the pair of hook-shaped recesses 98, 98 (engaging surface portions 98a, 98a) of the second hook portion 97 formed in 98, 98 (engagement surface portions 98 a, 98 a), the lower metal plate 125 is moved rearward, and the locking pieces 118, 118 of the second restricting portion 129 are moved to the second hooking portion 97. The contact surfaces 98a and 98a are brought into contact with and engaged with each other. Here, since the inclined surface 99 is formed on the lower surface portion 93 of the transparent cover body 90 at a position corresponding to each of the second hook portions 97, the lower plate portion 126 of the lower metal plate 125 is formed. The locking pieces 118, 118 of the second restricting portion 129 can be brought into contact with and engaged with the engaging surface portions 98a, 98a of the second hooking portion 97 in a posture inclined downward to the rear. That is, by tilting the lower metal plate 125, the rear plate portion 128 of the lower metal plate 125 can be prevented from interfering with the drum case 60, and when the lower metal plate 125 is moved backward, Since the locking pieces 118, 118 of the second restricting portion 129 are naturally guided along the inclined surface 99 toward the engaging surface portions 98a, 98a of the second hooking portion 97, each locking piece 118, 118 can be easily engaged with the engaging surface portions 98a and 98a of the second hooking portion 97, and the workability of assembling the lower metal plate 125 can be improved.

  Then, with the locking pieces 118, 118 of the second restricting portion 129 in contact with and engaging with the engaging surface portions 98a, 98a of the second hooking portion 97, the rear plate portion 128 of the lower metal plate 125 is moved. Positioning projections 64c and 64c formed on the rear case body 62 are formed on the rear plate portion 128 of the lower metal plate 125 by being moved close to the drum case 60 (the rear wall surface 64 of the rear case body 62). It fits in the positioning holes 128b and 128b. At this time, four pieces formed on the rear wall surface 64 of the rear case body 62 on the inner edges of the first positioning opening 128c and the second positioning opening 128d formed in the rear plate portion 128 of the lower metal plate 125. The positioning protrusion 64d abuts (see FIG. 18). That is, the positioning protrusions 64c and 64c are fitted in the positioning holes 128b and 128b, and the positioning protrusions 64d are formed on the inner edges of the first and second positioning openings 128c and 128d. The movement of the metal plate 125 in the vertical direction and the movement in the horizontal direction is restricted, and the lower metal plate 125 is temporarily fixed to the drum case 60.

  Similarly, a pair of hook-shaped recesses 98 of the first hooking portion 96 formed on the upper surface portion 92 of the transparent cover body 90 with the locking pieces 118, 118 of the first restricting portions 116 formed on the upper metal plate 111. , 98 (engagement surface portions 98a, 98a), the extension piece 117 of the first restricting portion 116 faces between the hook-shaped recesses 98, 98 (engagement surface portions 98a, 98a). Then, the upper metal plate 111 is moved rearward, and the locking pieces 118 and 118 of the first restricting portion 116 are brought into contact with and engaged with the engaging surface portions 98 a and 98 a of the first hook portion 96. Here, since the inclined surface 99 is formed on the upper surface portion 92 of the transparent cover body 90 at a position corresponding to each of the first hook portions 96, the upper plate portion 112 of the upper metal plate 111 is rearward. The locking pieces 118, 118 of the first restricting portion 116 can be brought into contact with and engaged with the engaging surface portions 98 a, 98 a of the first hook portion 96 in a posture inclined upward. That is, by tilting the upper metal plate 111, it is possible to avoid the rear plate portion 114 of the upper metal plate 111 from interfering with the drum case 60. The locking pieces 118, 118 of the first restricting portion 116 are naturally guided along the surface 99 toward the engaging surface portions 98a, 98a of the first hooking portion 96. The first hook portion 96 can be easily engaged with the engagement surface portions 98a and 98a, and the workability of assembling the upper metal plate 111 can be improved.

  Then, the rear plate portion 114 of the upper metal plate 111 is moved in the state where the locking pieces 118, 118 of the first restricting portion 116 are in contact with and engaged with the engaging surface portions 98 a, 98 a of the first hook portion 96. Positioning projections 64c, 64c formed on the rear case body 62 are moved toward the drum case 60 (rear wall surface 64 of the rear case body 62), and positioning holes formed on the rear plate portion 114 of the upper metal plate 111. 114b and 114b are fitted. At this time, four positionings formed on the rear wall surface 64 of the rear case body 62 at the inner edges of the first positioning opening 114c and the second positioning opening 114d formed on the rear plate 114 of the upper metal plate 111. The projecting piece 64d abuts (see FIG. 18). That is, the positioning protrusions 64c and 64c are fitted in the positioning holes 114b and 114b, and the positioning protrusions 64d are formed on the inner edges of the first and second positioning openings 114c and 114d. The movement of the plate 111 in the vertical direction and the movement in the horizontal direction is restricted, and the rear plate portion 114 of the upper metal plate 111 and the rear plate portion 128 of the lower metal plate 125 overlap each other with respect to the drum case 60. The upper metal plate 111 is temporarily fixed.

  At this time, each of the screw insertion hole 114 a formed in the rear plate portion 114 of the upper metal plate 111 and the screw insertion hole 128 a formed in the rear plate portion 128 of the lower metal plate 125 is formed in the rear case body 62. The said symbol display unit which accommodated in the drum case 60 the screw | thread inserted in each of each screw insertion hole 114a, 128a, 64b from the outer side of this upper metal plate 111 in alignment with the screw insertion hole 64b formed in the rear wall surface 64. The upper and lower metal plates 111 and 125 are fixed to the drum case 60 by being screwed into the second screw holes 29 a of the fixing pieces 29 of the 21 (support plate 23). As described above, when the upper and lower metal plates 111 and 125 are assembled to the drum case 60, the respective metal with respect to the first and second hook portions 96 and 97 formed on the upper and lower surface portions 92 and 93 of the transparent cover body 90. Since the locking pieces 118, 118 formed on the plates 111, 125 are engaged with each other correspondingly from the front side, it is only necessary to screw them to the rear case body 62 at the overlapping portions of the metal plates 111, 125. The metal plates 111 and 125 can be assembled by work.

  As described above, in the drum-type symbol display device 20 according to the embodiment, the metal frame member 110 attached to the outer surface of the drum case 60 has a divided structure including the upper metal plate 111 and the lower metal plate 125. Each of the upper metal plate 111 and the lower metal plate 125 can be individually attached to the case 60. That is, when a metal frame member formed by bending a single metal plate so as to cover a range from the upper surface of the drum case 60 through the rear surface to the lower surface is assembled to the drum case 60, the plate corresponding to the upper surface and the lower surface It is necessary to expand the portion and insert the drum case 60, which has a disadvantage of poor workability. On the other hand, in the embodiment, since the metal frame member 110 is divided into the upper and lower metal plates 111 and 125, a complicated operation of inserting the drum case 60 between the upper and lower metal plates 111 and 125 is required. Instead, the assembly workability can be improved. Further, since the upper and lower metal plates 111 and 125 can be fixed with screws to the drum case 60, the workability of assembling the upper and lower metal plates 111 and 125 is remarkably improved.

  Furthermore, as described above, the extending pieces 117 of the first and second restricting portions 116 and 129 in the upper and lower metal plates 111 and 125 correspond to the corresponding first and second hooking portions 96 in the transparent cover body 90. , 97 so as to face between a pair of bowl-shaped recesses 98, 98. Therefore, when assembling the upper and lower metal plates 111, 125 to the drum case 60, the metal plates 111, 125 are positioned in the left-right direction, and the locking pieces 118, 118 are held in a state where the metal plates 111, 125 are positioned. Since it can be engaged with the engagement surface portions 98a and 98a of the bowl-shaped recesses 98 and 98, the workability of attaching the metal plates 111 and 125 is greatly improved.

  The upper metal plate 111 and the lower metal plate 125 are configured to be fixed to the rear case body 62 (the fixing piece 29 of the symbol display unit 21) by the rear plate portions 114 and 128 overlapping each other. Compared with the case where the metal plates 111 and 125 are individually fixed, the integrity of the metal plates 111 and 125 is improved, and deformation and breakage of the drum case 60 can be more effectively prevented. Further, by screwing at the portion where the upper and lower metal plates 111 and 125 overlap, there is an advantage that the screwing locations of the metal plates 111 and 125 can be reduced and the working efficiency can be improved. Further, by fixing the upper and lower metal plates 111 and 125 with screws, the symbol display unit 21 accommodated in the drum case 60 is also fixed, so that it is possible to effectively suppress the backlash of the symbol display unit 21. .

  In order to dispose the control device 130 on the drum case 60, a first engagement protrusion 133 formed at the front end of the control device 130 is provided with a locking hole of the rising wall 119 formed on the upper metal plate 111. Insert into 119a. Thereafter, the second engaging protrusions 134 and 134 formed at the rear end of the control device 130 are engaged with the engaging recesses 143 and 143 of the fixing members 140 and 140, so that the fixing members 140 and 140 are engaged. Since the control device 130 is fixed to the upper surface of the drum case 60 by screwing to a screwing boss 74 provided on the support plate portion 73 of the rear case body 62, the control device 130 is installed by a simple operation. be able to.

  Here, in a state in which each of the symbol display units 21 is accommodated in the drum case 60, the first outlet hole 72 formed in the upper inclined surface 66 of the rear case body 62 and the upper inclined plate portion of the upper metal plate 111 are provided. The first rear end of the support plate 23 of the symbol display unit 21 protrudes outward from the case through the second outlet hole 122 opened in 113 and is connected to the control device 130 by wiring. The part 26a is located outside the case. Accordingly, each third connector receiving portion 132 of the control device 130 installed on the upper surface of the drum case 60 can be easily attached to and detached from the corresponding first connector receiving portion 26a, and the workability of wiring connection is improved. Figured. Here, each of the symbol display units 21 is configured to cut out a base metal plate 27 constituting the support plate 23 at a position corresponding to the first connector receiving portion 26a provided on the printed wiring board 24. A first connector receiving portion 26a is mounted on the printed wiring board 24 in such a manner that component leads protrude from the back surface through through holes. Therefore, since the first connector receiving portion 26a is firmly fixed to the printed wiring board 24 as compared with the surface mounting, the wiring from the control device 130 is attached to and detached from the first connector receiving portion 26a. In addition, it is possible to prevent inconveniences such as peeling of a portion fixed to the printed wiring board 24 (soldered portion). In particular, in the embodiment, the connector insertion port of the first connector receiving portion 26a is attached so as to face the rear side of the support plate 23, so that it protrudes from the first outlet hole 72 and the second outlet hole 122. When the connection to the first connector receiving portion 26a is facilitated, the load at the time of wiring connection acts in a direction parallel to the printed wiring board 24. Therefore, when the first connector receiving portion 26a is attached by surface mounting In this case, it is pointed out that the first connector receiving portion 26a may drop off. However, the first connector receiving portion 26a is mounted in a form in which the component leads are protruded on the back surface as in the embodiment. It is possible to effectively prevent the connector receiving portion 26a from falling off.

  In addition, since the support plate portion 73 is provided at four locations that are separated in the left-right direction of the rear case body 62, the control device 130 is installed on the upper surface of the drum case 60. The lower surface is supported by the support plate portion 73 at a plurality of locations, and the stability of the control device 130 is increased. Furthermore, each of the support plate portions 73 is configured to extend and support a predetermined length before and after the control device 130 (in the embodiment, about 1/3 of the front and rear dimension of the control device 130). The impact resistance is improved, and it is possible to prevent the control device 130 from falling off due to damage to the support plate portion 73 due to vibration during transportation of the pachinko machine.

  Further, the through holes 144 and 144 formed in the fixtures 140 and 140 and the screwing bosses 74 are formed only by aligning the groove portions 145 formed in the fixtures 140 and 140 with the support plate portion 73 and the reinforcing rib 73a. Since the third screw holes 74a and 74a formed in the first and second screw holes 74a and 74a are aligned with each other, the attaching work of the fixtures 140 and 140 can be easily performed. When the control device 130 is disposed on the upper surface of the drum case 60, the second position restriction piece 120 formed at the front end of the rising wall 119 and the upper plate portion 112 of the upper metal plate 111 is connected to the front end of the control device 130. The control device 130 is restricted from moving forward by being in contact with the portion. Further, a third position restricting piece 121 formed on the upper metal plate 111 abuts against the side surface of the control device 130 to restrict the movement of the control device 130 in the left-right direction, and is connected from the left and right side surfaces of the control device 130. The fixing portions 135, 135 abut against the front end of the third position restricting piece 121 and restrict the backward movement of the control device 130. That is, when the control device 130 is arranged on the upper surface of the drum case 60, the movement of the control device 130 in the front-rear direction and the left-right direction is restricted even before the fixing device 140 and 140 are fixed. Therefore, it is possible to prevent the control device 130 from falling off and to easily perform the fixing work using the fixtures 140 and 140.

  Further, when the control device 130 is disposed on the upper surface of the drum case 60, the lower surface of the control device 130 is attached to the first hook portion 96 formed on the transparent cover body 90 and the support plate portions 73. In contact with each other, a gap S is defined between the control device 130 and the metal frame member 110 (upper metal plate 111). Accordingly, the heat generated inside the drum-type symbol display device 20 (heat generated by driving the drive motor 31) is externally transmitted through the gap S between the control device 130 and the metal frame member 110 (upper metal plate 111). Therefore, there is an advantage that the control device 130 can be prevented from being adversely affected.
