[0037]
In the display control device M, the connector 35 of each of the symbol display units U and the corresponding connector 52 of the second substrate portion 47 are connected via a harness 36, respectively.
[0038]
In the symbol variable display device K of the embodiment assembled in this manner, as described above, the display 20 is handled as a single unit in a state where the fluoroscopic display body 20 is assembled in advance in the front opening of the housing box 21. be able to. In addition, since the front opening of the storage box 21 is covered with the transparent display body 20, entry of foreign matter such as dust and dirt into the box 21 is preferably avoided during storage and transportation after assembly is completed. Thus, the malfunction and failure of the symbol display unit U are preferably prevented, while the symbol drums 33 are not exposed, so that the drums 33 are prevented from being damaged or broken. Further, a frame-like protruding piece 72 for positioning the front case 29 in the housing box 21 and a support guide piece 71 for positioning and holding the drive base 31 in each symbol display unit U are formed on the rear surface side of the fluoroscopic display body 20. Therefore, the positioning of each symbol display unit U and the front case 29 with respect to the fluoroscopic display body 20 can be performed very simply and easily. Moreover, the front case 29 aligned with the fluoroscopic display body 20 is latched and held from both the inside and outside by the deformation restricting boss 73, and in particular, elastic deformation to the inside is restricted (FIG. 15).
[0039]
Further, regarding the see-through display body 20, the partition wall portions 69, 69 are provided on the back side of the see-through portion 23, and the thickness of the see-through portion 23 is set large. Even if the variable symbol display device K is placed on the floor or the like with the fluoroscopic display body 20 facing downward, deformation of the fluoroscopic portion 23 is preferably prevented. Of course, even if the fluoroscopic part 23 is pressed with a fingertip or the like, the fluoroscopic part 23 is not deformed. Therefore, the deformation | transformation of the see-through | perspective part 23 can prevent suitably the damage, breakage | break, etc. of the symbol drum 33 of each symbol display unit U inserted.
[0040]
The variable symbol display device K unitized as described above is formed in each support portion 27 of the safe ball guide member 15 in the pin hole 25a formed in each connection support piece 25 of the fluoroscopic display body 20. The transparent display body 20 is positioned and set by inserting the inserted pin 27a and inserting the pin 77 into the pin hole 75 formed in each support piece 74. The fluoroscopic display body 20 is locked in a connected state to the rear side of the safe ball guide member 15 by engaging with the connection hole 27b. At this time, the entire fluoroscopic display body 20 faces the front side from the fluoroscopic window 15a of the safe ball guide member 15, and the fluoroscopic part 23 is aligned with the visible display portion 67 of the large decorative part N mounted on the front side of the game board J from the back side. To do. Thus, in the symbol variable display device K of the embodiment, the pins 27a and 77 formed on the safe ball guide member 15 are simply positioned and inserted into the pin holes 25a and 75 formed on the fluoroscopic display body 20 in a corresponding manner. Positioning with respect to the game board J can be performed accurately and quickly, and can be easily mounted and fixed by only rotating the locking devices 26. The connector 53 disposed on the second board portion 47 of the display control device M is connected to a main control device (not shown) via a harness.
[0041]
In the pachinko machine P that implements the symbol variable display device K of the embodiment, a start input is input to the display control device M when a game ball launched during a game is detected by the start winning device 11. Based on the game, a symbol combination game is developed, and when a “hit” is generated as a result of the stop display of the winning symbol on the variable symbol display device K, a special game condition that opens the entrance of the large winning device L appears. It is supposed to be.
[0042]
In each symbol display unit U of the symbol variable display device K, the display control device M causes the illuminator 78 to correspond to each time point and each condition when “reach” occurs and “big hit” occurs in the symbol variation stop control. Necessary light emission control including blinking and lighting of the irradiation lamps 79, 79 is executed, and suitable illumination for each of the symbols S is performed. As a result, the symbol S stopped on the winning line clearly floats on the display window 24, and the entire see-through portion 23 is illuminated by the illuminators 78 in each symbol display unit U, and the entire visible display portion 67 is illuminated brightly. The
[0043]
Here, in the symbol variable display device K of the embodiment, the front side of the drive base 31 in each symbol display unit U is adjacent to the partition wall portions 69 and 69 or the side wall portion 68a in the perspective display body 20. Accordingly, in each of the partition wall portions 69 and 69, the irradiation light from the irradiation lamps 79 and 79 of the illuminating device 78 in the unit U adjacent to the partition wall portions 69 and 69 is transmitted laterally. It is expected that the lighting effect will be improved due to the brighter illumination. Further, in each of the side wall portions 68a and 68b, a large number of convex portions 70 are provided so that the light is diffused. Therefore, the irradiation lamps 79 and 79 of the illumination tool 78 in the left and right symbol display units U and U are provided. From the corresponding side wall portions 68a and 68b, the irradiated light is irradiated outward and reflected on the inner wall of the plated visible display portion 67, so that further improvement of the illumination effect can be expected. Since the side wall portions 68a and 68b and the partition wall portions 69 and 69 are all formed so as not to be seen through, the inside of each symbol display unit U is seen through from the front side of the pachinko machine P through the see-through portion 23. Not.
[0044]
In the symbol variable display device K of the embodiment, each display window 24 in the see-through portion 23 is formed in a lens shape (FIG. 16A), while the display region 24a is formed transparent and other non-displays are performed. Since the region 24b is made opaque, the symbols S stopped on the winning line are clearly enlarged and displayed, and the symbols S other than the winning line are unclearly displayed (FIG. 16B). Thereby, for example, when the jackpot symbol is aligned on the winning line, the symbol display of a high “big hit” grade is performed together with the lighting effect by the lighting tool 78. Further, even if the jackpot symbols are arranged other than the winning line, the player will not mistakenly recognize it as a “jackpot”.
[0045]
On the other hand, in the symbol variable display device K according to the embodiment, the display control board 44 of the display control device M that electrically controls each symbol display unit U is divided into two pieces and is opposed to the upper surface side of the housing box 21. A large component was mounted as an electronic component on the first substrate portion 46 positioned, and a small component was mounted as an electronic component on the second substrate portion 47 positioned opposite the rear surface side of the housing box 21. Thereby, the thickness dimension of the front-back direction of the part which faces the rear surface side of the storage box 21 in the display control device M can be reduced, and the pachinko machine P equipped with the symbol variable display device K is installed on the island in the game store. In this case, the amount of protrusion to the rear side can be reduced. That is, even if the symbol drum 33 of the symbol display unit U is enlarged by the thickness of the display control device M, the symbol variable display devices K, K facing each other in the island do not interfere with each other. Therefore, a powerful symbol display is possible by increasing the size of the symbol drum 33, and the interest of the entire game can be enhanced, and the overall pachinko machine can be upgraded.
[0046]
Further, in the display control device M, since a large heavy component is mounted on the first substrate portion 46 facing the upper surface side of the storage box body 21, the display control device M is mounted on the storage box body 21 (metal frame 22). It is excellent in stability and can be reliably and stably fixed with a single screw as in the embodiment. Note that large components mounted on the first substrate unit 46 generate heat and noise, but these components are separated from the CPU 50 and the IC 51 mounted on the second substrate unit 47. The influence of heat and noise on the IC 51 can be reduced. In addition, since a large number of heat radiation holes 55d and 59a are formed in the upper part of the substrate case 45, heat generated from the large components disposed in the upper part efficiently escapes to the outside and does not stay in the case. .
[0047]
The orientation of the connectors 52 and 53 arranged on the second board portion 47 is set so that the connection ports 52a and 53a extend along the arrangement surface of the board portion 47 (control board arrangement surface). Accordingly, the front and rear thicknesses of the portion of the display control device M facing the rear surface side of the storage box body 21 can be reduced. In addition, since the connector 35 of each symbol display unit U faces the rear lower portion of the housing box 21 and the corresponding connector 52 of the display control device M is disposed below the second substrate portion 47, both connectors 35, The harness 36 for connecting 52 can be shortened. That is, the material cost can be reduced, and the influence from noise caused by the length of the harness 36 can be suppressed.
[0048]
Further, in the symbol variable display device K of the embodiment, the connector 52 disposed on the second substrate portion 47 is directed downward and protected by the second case body 55, so the pachinko machine P is installed. It is possible to prevent a pachinko ball falling on the rear side of the pachinko machine P in the island from colliding with the connector 52 and causing damage or a short circuit. Furthermore, since the harness 36 is connected to the connector 52 from below, the harness 36 also does not protrude rearward from the arrangement surface of the second board portion 47, and the pachinko ball collides with the harness 36. Can also be prevented.
[0049]
[Example of change]
FIGS. 17A and 17B are a side sectional view and a front view of the see-through portion 23 of the see-through display body (front cover member) 20 according to the modification. In the see-through display body 20 of this modified example, each display window 24 in the see-through unit 23 is formed in a lens shape by increasing only the thickness of the display area 24a corresponding to the winning line, and the upper and lower non-display areas 24b. The wall thickness is set small. In the symbol variable display device K that implements the fluoroscopic display body 20 as such a fluoroscopic part 23, only the symbol S stopped on the winning line is clearly enlarged and displayed, and the symbol S stopped outside the winning line is unclear. In combination with the lighting effect of the lighting tool 78 of each symbol display unit U, the misperception of the occurrence of “big hit” by the player is further preferably avoided.
[0050]
The variable symbol display device as a large accessory to be the subject of the present invention is not shown, but is suitable for a variable symbol display device in the form using a symbol belt (display means) in addition to the above-described embodiment using the symbol drum.

The plurality of substrate parts constituting the substrate are opposed to the upper surface and one side surface, the rear surface and one side surface, or the upper surface and both side surfaces, or the rear surface and both side surfaces, in addition to being opposed to the upper surface and rear surface of the housing box. It can be set as the structure to be located. Furthermore, the heat radiating holes provided in the substrate case may be provided in the upper plate or the upper side plate of the second case body. In addition, although the case where it divided | segmented into two was demonstrated as said storage box, the one box opened in the front-back direction may be sufficient.
[0052]
【The invention's effect】
  As described above, in the large-sized gaming machine of the pachinko gaming machine according to the present invention,pluralA front cover member is assembled in advance in the front opening of the housing box that houses and sets the symbol display unit, and can be handled as a single unit in this state. As a result, since the front opening of the storage box is covered with the front cover member, entry of foreign matter such as dust and dirt into the box during storage and transportation after assembly is preferably avoided. While malfunction of the display unit and occurrence of a failure are preferably prevented, the symbol display body is not exposed, so that a beneficial effect of preventing damage or breakage of the display body is obtained. Since the support portion for positioning and holding the symbol display unit is formed on the back side of the front cover member, there is an advantage that the symbol display unit can be positioned very simply and easily with respect to the front cover member..
