Description

  The present invention relates to a pachinko gaming machine provided with a translucent gaming board.

The pachinko gaming machine is equipped with a gaming board and a symbol display arranged side by side in the front and rear direction on the inner frame so that the player can visually recognize the display contents of the symbol display through the gaming board, or the entire area of the gaming board or the gaming board There is a display that can use a large-screen symbol display that covers the entire vertical direction. In this configuration, the amount of heat generated by the symbol display increases with the size of the screen, so the heat generated by the symbol display is based on the interposition of a frame-shaped spacer between the game board and the symbol display. Is not transmitted to the game board side. In the case of this pachinko gaming machine, each of the game board and the symbol display is detachably attached to the inner frame, and the translucent game board is replaced with another translucent game while leaving the symbol display on the inner frame. The board can be replaced. For this reason, in a veneer game board in which the symbol display must be made smaller than the light-transmitting game board, the light-transmitting pattern display fixed to the inner frame described above remains on the inner frame. Interfering with the game board symbol display becomes a problem. Therefore, the same inner frame cannot be used between the translucent game board and the non-translucent veneer game board. Therefore, the applicant of the present invention forms a unit by joining the three members of the game board, the spacer, and the symbol display together, and the translucent game board and veneer are based on replacing the game board in units when changing the board. It was proposed to use the inner frame between game boards made by the manufacturer.

  In pachinko machines, veneer game boards are generally used. In the case of this general pachinko gaming machine, the symbol display is housed in the case, and the case is joined to the rear surface of the game board so that the display area of the symbol display is visible behind the opening of the game board. It is arranged. This case is made of synthetic resin, and has the effect of reducing the impact force acting on the symbol display when the game board is transported and when the window frame is opened and closed. However, when trying to join a large screen symbol display to a translucent game board through a synthetic resin case, a wide flange is formed around the symbol display in the case, and the wide flange is attached to the game board. It is necessary to secure enough strength to support the heavy symbol display by joining to the rear surface. For this reason, since the joining position of a wide flange is limited by the relationship with other parts, there exists a possibility of causing the deterioration of the assembly workability | operativity of a symbol display, and the instability of the assembly posture of a symbol display. Therefore, the structure which joins a symbol display to a game board through a case cannot be employ | adopted, but the new device which relieves the impact force which acts on a symbol display is requested | required. In addition, when the three members of the translucent game board, the spacer, and the symbol display are unitized, the weight balance of the entire game board unit is biased to the rear side by the total of the weight of the case and the weight of the spacer. For this reason, handling of the game board becomes difficult when the game board is mounted on the inner frame at the manufacturing stage and when it is replaced at the time of changing the board. Ingenuity is also required.

  The present invention has been made in view of the above circumstances, and an object thereof is to reduce the influence of heat generated by the symbol display on a translucent game board, and to reduce the weight balance of the entire game board. An object of the present invention is to provide a pachinko gaming machine that can protect a symbol display from an impact without being largely biased to the side.

1. Description of pachinko gaming machine according to claim 1 The pachinko gaming machine according to claim 1 is characterized in that it includes [1] game board to [6] spring screw.
[1] The game board has a game area in which a game ball can roll and has translucency. Reference numeral 30 in FIG. 2 is an example of a game board, and reference numeral 37 in FIG. 2 indicates a game area.
[2] The entrance device is provided in the game area of the game board, and can be switched between a closed state where the game ball cannot enter and an open state where the game ball can enter. Is. The special electric winning device 42 in FIG. 2 is an example of a ball opening device, and FIG. 2 shows the special electric winning device 42 in a closed state.
[3] The symbol display has a display area for displaying a video game image for identifying a big hit that opens the entrance device and a release that does not open the entrance device. It is provided behind the game board so that it can be visually recognized through the game area of the game board. Reference numeral 170 in FIG. 3 is an example of a symbol display. The liquid crystal panel 171 of FIG. 3 is an example of a display area. The liquid crystal panel 171 displays an image of a symbol game that sequentially displays the identification symbols in a variable state and a variable stop state.
[4] The spacer is provided between the game board and the symbol display, and has a frame shape surrounding the display area of the symbol display. For this reason, since the distance between the two becomes longer than in the case where the symbol display is directly joined to the rear surface of the game board, it is possible to suppress the heat generated by the symbol display from being transmitted to the game board. A reference numeral 90 in FIG. 2 is an example of a spacer, and the spacer 90 includes a back cover 60 and a frame 80.
[5] The stay connects the symbol display to the game board, and is composed of a metal plate integrally having a board side plate joined to the game board and a counter board side plate joined to the symbol display. . For this reason, since the strength of the stay is higher than that of the case made of synthetic resin, the width dimension of the board side stay can be made narrower than that of the flange made of synthetic resin. Accordingly, since the restriction on the joining position of the board side stays is reduced, it is possible to prevent deterioration of the assembling workability of the symbol display and instability of the assembling posture of the symbol display. The counterboard side plate supports only the edge of the symbol display, and supports at least either the left edge or the right edge. For this reason, a stay is reduced in weight compared with the case where the case-like stay which supports the whole symbol display is used. Therefore, since the weight balance of the entire game board is prevented from being greatly biased backward, handling of the game board is facilitated when the game board is mounted on the inner frame at the manufacturing stage and when the game board is replaced when the board is changed. The liquid crystal stay 130 in FIG. 3 is an example of a stay. The liquid crystal stay 130 includes a left liquid crystal stay 140 and a right liquid crystal stay 150, and each of the front plate 141 of the left liquid crystal stay 140 and the front plate 151 of the right liquid crystal stay 150 corresponds to a panel side plate. Each of the left side plate 142 of the left liquid crystal stay 140 and the right side plate 152 of the right liquid crystal stay 150 corresponds to a counter-plate side plate, and the left side plate 142 supports only the left edge of the symbol display 170, and the right side plate. 152 supports only the right edge of the symbol display 170.
[6] The spring screw joins the game board and the board side plate to each other, and has a screw and a spring. The screw is fixed to the game board so as not to move, and is attached to the stay so as to be slidable with respect to the game board. The spring is inserted into the outer periphery of the screw, and when the impact force is applied when the game board is transported or when the window frame is opened or closed, the spring is elastically deformed to reduce the impact force acting on the stay. To do. For this reason, since it is suppressed that an impact force is transmitted from a stay to a symbol display, a symbol display can be protected from an impact. Reference numeral 160 in FIG. 5 is an example of a spring screw, and reference numeral 161 indicates a screw. Each of the front spring 165 and the rear spring 166 inserted into the outer peripheral portion of the screw 161 corresponds to a spring.
2. Description of the pachinko gaming machine according to claim 2 The pachinko gaming machine according to claim 2 differs from the pachinko gaming machine according to claim 1 in that [7] spring screws are used instead of [6] spring screws. .
[7] The spring screw is for joining the symbol display and the counterboard side plate of the stay to each other, and has a screw and a spring. The screw is fixed to the symbol display unit so as not to move, and is attached to the stay so as to be slidable with respect to the stay. The spring is inserted into the outer periphery of the screw, and when the impact force is applied when the game board is transported or when the window frame is opened or closed, the impact force acting on the symbol display is based on the elastic deformation of the spring. To ease. Reference numeral 160 in FIG. 6 is an example of a spring screw, and reference numeral 161 indicates a screw. Each of the left spring 167 and the right spring 168 inserted into the outer peripheral portion of the screw 161 corresponds to a spring.

10. Description of Symbol Game As shown in FIG. 7A, the liquid crystal panel 171 of the symbol display 170 has “1”, “1” as the symbol element in the left column, the symbol element in the middle column, and the symbol element in the right column. Any of the numbers “2”, “3”, “4”, “5”, “6”, “7”, and “8” is displayed in the variable stop state, and the game ball is in the upper start opening 43 and below the electric starter 41. When winning in any one of the start ports 44, as shown in FIG. 7B, the three rows of symbol elements change from the variable stop state to the variable state. In this variation state, eight types of symbol elements “1” to “8” arranged in a vertical row are scroll-displayed so that the display range moves in the vertical direction, and the symbol elements in each column are from top to bottom. While moving, it changes cyclically in the order of “1” → “2” → “3” → “4” → “5” → “6” → “7” → “8” → “1”. These symbol elements in the left column, the symbol elements in the middle column, and the symbol elements in the right column constitute a decorative symbol. The decorative symbols are (1) symbol elements in the left column (2) symbol elements in the right column (3) Fluctuation stops in the order of symbol elements in the middle row.

  When both the symbol elements in the left column and the symbol elements in the right column are variably stopped, a combination of reach is selectively displayed. As shown in FIG. 7 (c), this reach combination refers to a combination in which the symbol elements in the left column and the symbol elements in the right column are identical to each other. This refers to a narrative-like video that directs whether or not the symbol element stops changing at the same number as both the symbol element in the left column and the symbol element in the right column. (D) to (f) of FIG. 7 show examples of effect images, and depending on whether the shrine can withstand the heat of the bath, the symbol elements in the middle row are the symbol elements in the left column and the symbol elements in the right column. Whether or not the change is stopped is produced with the same number as both.

  The jackpot game is started when the jackpot combination is started when all of the symbol elements in the left column, the right column, and the middle row of the symbol elements are in a variable stop state, and the combination is an outlier that is different from the jackpot combination. When hit, the big hit game will not start. The jackpot combination refers to a combination in which the symbol element in the left column, the symbol element in the middle column, and the symbol element in the right column are the same, and for the jackpot combination, “111” “222” “333” “444” Eight kinds of “555”, “666”, “777”, and “888” are set. The big hit game opens the door 46 of the special electric prize-winning device 42 and generates a player-favorable state that allows the game ball to win in the special winning opening of the special electric prize-winning device 42. The game is held in an open state until the condition for the number of game balls having an upper limit value (for example, 10) to win in the winning opening or the time condition for reaching the upper limit value (for example, 30 sec) is satisfied. The opening / closing operation based on the number condition and the time condition of the doors 46 is called a big hit round, and the big hit round is repeated a fixed number of times (for example, 15 times).

According to the said Example 1, there exists the following effect.
Since the frame-shaped spacer 90 is interposed between the game board 30 and the symbol display 170, the distance between the two becomes longer than when the symbol display 170 is directly joined to the rear surface of the game board 30. For this reason, since heat generated in the symbol display 170 is suppressed from being transmitted to the game board 30 side, it is possible to reduce the influence of heat generated by the symbol display 170 on the game board 30.

  The liquid crystal stay 130 is composed of a left liquid crystal stay 140 made of a metal plate and a right liquid crystal stay 150 made of a metal plate. For this reason, since the strength of the liquid crystal stay 130 is higher than that of the case made of synthetic resin, the width dimension of the front plate 141 of the left liquid crystal stay 140 and the width dimension of the front plate 151 of the right liquid crystal stay 150 are measured. Each can be made narrower than the flange of the synthetic resin case. Accordingly, since the restriction on the joining position of the front plate 141 and the restriction on the joining position of the front plate 151 are reduced, the assembling workability of the symbol display 170 is deteriorated and the assembling posture of the symbol display 170 is unstable. Is prevented.

  Since the left side plate 141 of the liquid crystal stay 130 supports only the left side edge of the symbol display 170, and the right side plate 151 of the liquid crystal stay 130 supports only both the right side edge of the symbol display 170, the symbol is displayed. The liquid crystal stay 130 is reduced in weight compared to the case where a case-like stay that supports the entire display 170 is used. For this reason, since the weight balance of the game board unit 20 is prevented from being greatly biased to the rear, the game board unit 20 is attached to each of the case where the game board unit 20 is mounted on the inner frame 2 at the manufacturing stage and when the board is replaced when the board is changed. Is easy to handle.

  Each of the left liquid crystal stay 130 and the right liquid crystal stay 140 is joined to the game board 30 via a spring screw 160. For this reason, the left liquid crystal stay 130 is based on the elastic deformation of the front spring 165 and the rear spring 166 of the spring screw 160 when an impact force is applied when the game board unit 20 is transported or when the window frame 17 is opened or closed. The impact force acting on the right liquid crystal stay 140 is alleviated. For this reason, since the impact force is prevented from being transmitted from the left liquid crystal stay 130 and the right liquid crystal stay 140 to the symbol display 170, the symbol display 170 can be protected from the impact.

  Each of the left liquid crystal stay 130 and the right liquid crystal stay 140 was joined to the symbol display 170 via a spring screw 160. For this reason, the symbol display 170 is based on the elastic deformation of the left spring 167 and the right spring 168 of the spring screw 160 when an impact force is applied when the game board unit 20 is transported or when the window frame 17 is opened or closed. Since the impact force acting on the symbol is reduced, the symbol display 170 can be protected from the impact from this point.

  The panel frame 172 of the symbol display 170 is made of an elastomer having rubber elasticity. Therefore, when an impact force is applied when the game board unit 20 is transported or when the window frame 17 is opened / closed, the panel frame 172 is elastically deformed to reduce the impact force. 170 can be protected from impact.

In the first embodiment, the front plate 141 of the left liquid crystal stay 140 and the front plate 151 of the right liquid crystal stay 150 may be joined to the game board 30 so as not to move.
In the first embodiment, the left side plate 142 of the left liquid crystal stay 140 and the right side plate 152 of the right liquid crystal stay 150 may be joined to the symbol display 170 so as not to move.

  In the first embodiment, instead of the liquid crystal stay 130, a rectangular frame-like stay having a horizontally long lower stay, a horizontally long upper stay, a vertically long left stay, and a vertically long right stay may be used.
