The present invention relates to a large-sized game apparatus that can reveal special game conditions.
[0002]
[Prior art]
As a representative example of this type of gaming machine, in a conventionally known pachinko machine, a special combination game is developed by developing a symbol combination game based on variable control conditions including each start and stop generated during the game. As a large-sized game apparatus capable of establishing and displaying a combined winning condition that is a right related to a state, various symbol variable display devices called a drum type and a belt type are adopted. Among these, for example, in the drum-type symbol variable display device, even if there is a difference in size, variation control condition, etc. depending on the target pachinko machine, as a basic form, a flat pulley type molded as a symbol display body as a synthetic resin The design drum (with various types of identification symbols such as numbers, alphabet letters, and other figures and marks arranged on the outer periphery of the rotating body that is the base of the drum) and the design drum A symbol display unit is formed for each unit including a rotation drive means (generally a stepping motor), a positioning detection means for each symbol to be stopped, illumination means, and the like. This symbol display unit is set in parallel in a drum case with a plurality of units (usually three units in the left column, middle column, and right column) as a group unit.
[0003]
Such a symbol variable display device is attached to and fixed to the back of the game board, for example, so that the visible display part of the see-through window formed in the large decorative part assembled at the center of the front of the game board is formed. The symbol drums of the symbol display units are fixed to face each other. In addition, a transparent resin front cover member that can see through the design of the design drum is inserted between the design variable display device and the visible display portion, and depending on the start signal input condition generated during the pachinko game. Based on the control output generated from the display control device, the symbol drums of the symbol display units in each row rotate and stop under the set time condition, and each symbol is displayed on the winning line in a transparent manner.
[0004]
[Problems to be solved by the invention]
By the way, in the game board of the conventional pachinko gaming machine, the front cover member is configured to be assembled on the large decorative part side, and the drum case of the symbol variable display device has a large front side aligned with the visible display part.

The second substrate portion 47 is positioned in a state where the four corners are sandwiched from the front and rear by the boss 58 of the first case body 54 and the boss 62 of the second case body 55. The connectors 52 and 53 disposed on the second substrate 47 are covered by the corresponding protective recesses 63 and 64 provided on the second case body 55 except for the connection ports 52a and 53a. (See FIG. 7).
[0037]
As shown in FIG. 7, the display control apparatus M assembled as described above places the upper plate 54 a of the first case body 54 on the upper plate 38 of the metal frame 22 and also the main body plate 54 b of the first case 54. Is positioned and placed in contact with the rear surface of the body plate 37 of the metal frame 22. At this time, both side portions (upper side plate 55 b and lower side plate 55 e) of the substrate case 45 are sandwiched between the support pieces 40 and 40 and the second positioning pieces 42 and 42 of the metal frame 22. Further, the first positioning pieces 41 of the metal frame 22 engage with the claw pieces 65 and 65 of the substrate case 45, so that the display control device M is reliably positioned with respect to the metal frame 22. Then, the screw 66 inserted from the rear side (upper side) into the through hole 61b formed in the second case body 55 is screwed into the screw hole 43a formed in the attachment piece 43 of the metal frame 22, so that The display control device M is disposed and fixed on the rear side of the metal frame 22, that is, the housing box 21.
[0038]
The display control device M and each of the symbol display units U are electrically connected by connecting the connectors 52 and the connectors 35 with a harness 36. Since the connector 35 and the connector 52 are positioned adjacent to each other, the harness 36 having a short overall length can be used, and the material cost for the harness can be reduced.
[0039]
As described above, in the symbol variable display device K of the embodiment, the front case 29 of the housing box 21 and each symbol display with respect to the rear surface side of the perspective display member 20 serving as a reference regarding the assembling and assembling operations of the respective constituent members. The unit U, the rear case 30 of the storage box 21, the metal frame 22, and the display control device M can be assembled and assembled sequentially from the same rear side. In addition, the screw 69 for connecting the fluoroscopic display body 20 and the metal frame 22 and the screw 66 for connecting the metal frame 22 and the display control device M can also be screwed from the same direction as the assembly direction of each member. . Accordingly, there is no need to lift and change the orientation of the temporarily assembled member during assembly, and the assembly operation can be facilitated and rationalized.
[0040]
In the assembled symbol variable display device K of the embodiment, as described above, the transparent display body 20, the housing box 21 that houses the symbol display unit U, the metal frame 22, and the display control device M are assembled in advance. It can be handled as a single unit, facilitating handling and management. In addition, since the front opening of the storage box 21 is covered with the fluoroscopic 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.
[0041]
Further, with respect to the storage box 21, the three symbol display units U are stored and set through the rear opening of the case 29 with respect to the front case 29 positioned on the back side of the fluoroscopic display body 20. Since the assembling operation is completed simply by aligning and abutting the rear case 30 against the rear end side of the front case 29, the set-up of the symbol display unit U with respect to the containing box 21 is simple and reliable. You can do it. Moreover, in the rear case 30, the suitability of the drive base 31 with respect to the inner support guide piece 76 can be easily visually confirmed from the outside (rear side) of the case 30 through the confirmation hole 77. Assembling mistakes of each symbol display unit U can be reliably avoided, and the assembling work can be rationalized and facilitated.
[0042]
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. In addition, the front case 29 aligned with the fluoroscopic display body 20 is latched and held from both the inner and outer sides by the frame-shaped projecting piece 72 and the deformation restricting boss 73, and the inner side of the front portion of the left and right side frame members 29c Deformation is regulated. Further, the front case 29 is also latched and held from the inside by a deformation restricting boss 75 extending forward from the rear case 30, and deformation of the front case 29 to the inside of the rear portion of the left and right side frame members 29 c is also possible. Be regulated. Therefore, although the front case 29 is formed in a rectangular tube shape, the deformation of the left and right side frame members 29c is suitably restricted by the locking and reinforcing action by the deformation restriction boss 73 and the deformation restriction boss 75.
[0043]
Further, the back surfaces of the positioning protrusions 34 of the drive base 31 that extend downward through the relief openings defined by the notches 29b and 30b are substantially entirely covered by protective plates 29d and 30d that are connected to each other in a plate shape. Since it is protected, inconveniences such as a short circuit caused by a pachinko ball colliding with an electric circuit (conduction portion) formed on the back surface of the projecting piece 34 are preferably avoided. Moreover, since the relief opening defined by the notches 29b and 30b can be set to the minimum length necessary to allow the positioning protrusion 34 to be inserted, the strength of the housing box 21 due to the formation of the relief opening. Degradation is minimized.
[0044]
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. With the pin 27a inserted and positioned, the lock 26 can be mounted on the game board J in a single step by simply rotating and engaging the corresponding connecting hole 27b. It is possible to greatly rationalize the attachment work. Thereby, the see-through portion 23 of the see-through display body 20 faces the visible display portion 67 of the large decorative part N via the see-through window 15 a of the safe ball guide member 15. Further, the connector 53 disposed on the second substrate 47 of the display control device M is connected to a main control device (not shown) via a harness.
[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]
In the symbol variable display device K of the embodiment configured as described above, the storage box body 21 is held in a state surrounded by the fluoroscopic display body 20 and the metal frame 22. The weight of each symbol display unit U accommodated and set is added to the metal frame 22, and deformation or breakage of the accommodation box 21 due to the weight of the unit U is suitably prevented. Further, since the weight of the display control device M mounted on the back side of the metal frame 22 is also added to the metal frame 22 and not added to the storage box body 21, the storage box body by the weight of the display control device M is added. The deformation and breakage of 21 are also suitably prevented.
[0050]
Further, since the metal frame 22 is disposed between each symbol display unit U housed and set in the housing box 21 and the display control device M, the stepping motor 32 of the symbol display unit U is driven when the stepping motor 32 is driven. The noise generated from the motor is preferably shielded, and this noise preferably adversely affects the power supply component 48, the capacitor 49, the CPU 50, the IC 51, etc. of the first substrate unit 46 and the second substrate unit 47 of the display control device M. To prevent.
[0051]
(Reverse mounting mode)
On the other hand, in the symbol variable display device K of the embodiment, the screw hole 28a provided in the fluoroscopic display body 20 is formed as a through hole that opens to the front side of the display body 20 and allows the screw 69 'to be inserted. If it is assumed that the screw 69 'can be screwed into the slits 38b and 39b, the housing box 21 including the transparent display body 20, the front case 29, and the rear case 30, and each symbol display unit U It is also possible to assemble the respective members of the display control apparatus M, which accommodates the metal frame 22 and the display control board 44, sequentially assembled in the opposite direction (the front side (arrow B direction in FIG. 15)). That is, as an assembling mode based on the display control device M that accommodates and assembles the substrate portions 46 and 47, for example, with the front side of the display control device M fixed in a horizontal posture facing upward. The metal frame 22 is set on the front side of the display control device M, the screw 66 'is screwed from the front side, and then the rear case 30 of the storage box 21 is set on the front side of the metal frame 22, Each symbol display unit U is accommodated and set in the rear case 30. Then, the front case 29 is set on the front side of the rear case 30, and finally the transparent display body 20 is set on the front side of the front case 29, and the screw inserted from the front side through the screw hole 28a of the display body 20 When 69 'is screwed to the metal frame 22, it is assembled as a single unit body.
[0052]
