[Pachinko machines with polishing equipment]
Next, an overview of the pachinko gaming machine according to the present embodiment will be described with reference to FIGS. In the embodiment described below, as a preferred embodiment for a gaming machine provided with the gaming information display device (game information display device 900 for each gaming machine) of the present invention, a first type pachinko gaming machine (“digital pachi”) is also used. The case of using (referred to as) is shown. FIG. 3 is a diagram showing an appearance of a pachinko gaming machine 1100 as a gaming machine according to the present embodiment. In this embodiment, a so-called enclosed game machine in which a game progresses in a state in which a game ball is enclosed in the game machine is used as the pachinko game machine.

  The pachinko gaming machine 1100 includes a launching device 1110, a polishing device 1, and a lifting device 1130. The launching device 1110 is located above a gaming area 1140 covered by a permeable plate-shaped protective glass installed on the front surface of the pachinko gaming machine 1100, and launches the gaming ball 10 from above to the gaming area 1140. To do. Thereby, in the pachinko gaming machine 1100, a so-called return ball can be avoided. The return ball is generated in a general gaming machine having a structure in which a game ball launched from a launching device provided below the game area is discharged upward from the end of the path to the game area through the path. This is a phenomenon in which a game ball directed upward through the passage is not released from the end of the passage to the game area, passes through the passage downward from the top, and returns to the launching device again.

  The polishing apparatus 1 polishes the game ball 10 discharged from the game area 1140 after rolling the game area 1140. Here, the polishing apparatus 1 is configured such that a polishing unit 3 having a polishing cloth 4 is attached to a pair of guide rails 2 that are inclined in the longitudinal direction, and a game ball is placed on the pair of inclined guide rails 2. 3 rolls in the direction of arrow B in FIG. 3 due to its own weight, the lower surface of the game ball 10 and the polishing pad 4 come into contact with each other, the game ball 10 is polished, and the surface of the game ball 10 is removed.

  Thus, the polishing apparatus 1 is simple because the game ball 10 rolls on the pair of guide rails 2 due to its own weight, and the game ball 10 and the polishing cloth 4 come into contact with each other so that the game ball 10 is polished. The game ball 10 can be polished with a small configuration.

  The lifting device 1130 transports the game ball 10 polished by the polishing device 1 upward and guides it to the launching device 1110. The game balls 10 are not discharged to the outside of the pachinko gaming machine 1100, and a fixed number (for example, 50) of the game balls 10 are configured to circulate through a series of paths in the pachinko gaming machine 1100. Since the game balls 10 are not discharged outside the pachinko gaming machine 1100, the pachinko gaming machine 1100 is not provided with an upper plate or a lower plate for temporarily holding the game balls 10 discharged outside. Here, specifically, the series of paths are the launching device 1110, the game area 1140, the polishing device 1, and the lifting device 1130.

  In the pachinko gaming machine 1100, since the game balls 10 are not discharged to the outside, the game balls 10 are not actually in the hands of the player, and the game balls 10 are not actually increased or decreased by playing a game. In the pachinko gaming machine 1100, the player starts playing a game after obtaining a ball by lending from the game medium management device 1400. Then, when the game ball 10 is fired from the launching device 1110, the possession number as a player's possession ball is consumed, and the possession number decreases. This information indicating the decreased number of ownership is called subtraction information. In addition, when the game ball 10 passes through each winning opening provided in the gaming area 1140, the number of possessions increases by paying out according to the conditions set according to the winning opening. This information indicating the increased number of ownerships is called addition information. Furthermore, the number of possessions also increases by lending from the game medium management device 1400.

  In the present embodiment, “game media consumption, lending, and payout” means that the holding ball (number of possessions) is consumed, lent, and paid out. Further, “increase / decrease in game media” indicates that the number of possessions increases / decreases due to consumption, lending and payout. Further, “data relating to increase / decrease in game media due to consumption, lending and payout of game media” is data relating to a decrease in the number of possessions due to the game ball 10 being launched and an increase in the number of possessions due to the lending and payout. .

  The pachinko gaming machine 1100 has a payout control board and a touch panel type liquid crystal display (not shown). The main control board is connected to various sensors that detect the passing of the game ball 10 such as each winning opening. The payout control board manages the possession number which is the number of the player's balls. For example, when the game ball 10 passes through each winning opening, the number of game balls 10 to be paid out is added to the number of possessions. When the game ball 10 is fired, the possession number is subtracted. The payout control board transmits data on the number of possessions to the game medium management device 1400 by the player's ball lending or counting operation. The touch panel type liquid crystal display accepts a request for conversion from a game value managed by the game medium management device 1400 to a possessed ball (ball lending) and a count (return) of the possessed ball. These requests are transmitted to the payout control board via the game medium management apparatus 1400, and the payout control board instructs the game medium management apparatus 1400 to transmit data relating to the current number of possessions.

  Here, “game value” refers to money / banknotes, prepaid media, tokens, electronic money, tickets, and the like that can be converted into possessed balls by the game media management device 1400. In the present embodiment, the game medium management device 1400 is a so-called CR unit, and is configured to accept bills and prepaid media. The counted ball can be used for prize exchange or the like in a game hall or the like where a game system (not shown) is installed.

  The game medium management device 1400 has a bill insertion slot 1421 into which a bill can be inserted and a prepaid medium insertion slot 1422 into which a prepaid medium can be inserted. Thereby, the game media management apparatus 1400 can accept banknotes and prepaid media from the outside, and can manage game values. Although not shown, the game medium management apparatus 1400 may also have an insertion slot into which a member card in which information such as a member ID for identifying a player is recorded can be inserted. In the present embodiment, the game value received by the game medium management device 1400 is referred to as “balance”. In addition, the game medium management device 1400 transmits data relating to the balance and data relating to lending to the pachinko gaming machine 1100. Based on this data, the pachinko gaming machine 1100 displays the balance and the number of possessions. Further, when the player performs a counting (returning) operation of the ball in the pachinko gaming machine 1100, the game medium management device 1400 receives data regarding the number of possessions transmitted from the pachinko gaming machine 1100.

  As shown in FIGS. 4 to 8, the pachinko gaming machine 1100 includes a glass door 1511 having a front glass, an outer frame 1512, a base door 1513, a game board 1514 having a game area 1140, and a game for displaying an image.

The glass door 1511 is pivotally attached to the base door 1513 through these hinges 1519 and 1518B so as to be freely opened and closed. FIG. 5 shows a state where the glass door 1511 is opened.

  In addition, an opening 1516 is formed in the center of the glass door 1511, and a transparent protective glass 1524 is disposed in the opening 1516. Further, the outer frame 1512 described above has hinges 1517 above and below one side edge portion, and the hinge 1518A on the base door 1513 side is pivotally supported by these hinges 1517 so that the base door 1513 is externally attached. The frame 1512 is pivotally supported so as to be rotatable.

  Further, in the pachinko gaming machine 1100, a touch panel type liquid crystal display (not shown) is disposed on the base door 1513 so as to be positioned below the glass door 1511.

  The firing handle 2026 is disposed on the base door 1513 so as to be positioned below the glass door 1511. The pachinko game can be advanced by operating the launch handle 2026 by the player. When the firing handle 2026 is gripped by the player and is rotated in the clockwise direction, electric power is supplied to the firing motor of the launching device 1110 according to the turning angle, and the game is played from the launching device 1110. Balls are sequentially fired on the game board 1514.

  The game board 1514 is disposed in front of the base door 1513 so as to be positioned behind the protective glass 1524. The game board 1514 has a game area 1140 on the front surface of which the launched game ball can roll. The game area 1140 is an area in which a game ball fired by the launching device 1110 from above can roll. In this way, the game ball 10 launched by the launching device 1110 falls toward the lower side of the game board while changing its traveling direction due to a collision with a plurality of obstacle nails provided in the game area 1140.

  In the center of the front surface of the game board 1514, a start port 1141A, a shutter 1145, and the like are provided. On the condition that a game ball has entered the start port 1141A, variable display of a special symbol is executed. Further, as will be described in detail later, depending on the result of variable display of this special symbol, a big hit gaming state (so-called “big hit”) that is relatively advantageous to the player over the normal gaming state is obtained. When the big hit game state is reached, the shutter 1145 is controlled to be in the open state, and the game ball may be easily opened in the big prize opening 1144.

  Behind the game board 1514, a display area 2073A of the liquid crystal display 2073 for the game board is disposed so as to be visible. A speaker 1151 is disposed above the base door 1513.

  A special symbol display device 1161 is disposed in the center of the game board 1514. This special symbol display device 1161 performs variable display of special symbols in a special symbol game. The special symbol in the special symbol display device 1161 is configured by a single symbol sequence, but is not limited thereto, and may be configured by, for example, a plurality of symbol sequences. This special symbol is a symbol made up of numbers and symbols.

  “Variable display” is a concept that can be displayed in a variable manner. For example, a “variable display” that is actually displayed in a variable state and a “stop display” that is displayed in a stopped state. It is. In addition, “variable display” can be “derivation display” in which identification information is displayed as a result of a special symbol game. Further, the period from the start of the variable display to the derivation display is referred to as one variable display.

  In addition, the special symbol display device 1161 performs derivation display of the special symbol, and the gaming state is changed to a big hit gaming state advantageous to the player based on the special symbol that has been derived and displayed in a specific display mode. Will be migrated. In addition, when the special symbol derived and displayed is in a non-specific display mode, it does not shift to the big hit gaming state.

  Also, based on the fact that the special symbol that has been derived and displayed has become a special display mode among the specific display modes, the gaming state is shifted to a big hit gaming state that is advantageous to the player, and the big hit gaming state ends. In such a case, the state will be shifted to the probability variation state.

  On the other hand, based on the fact that the special symbol derived and displayed has become a non-special display mode that is not a special display mode among the specific display modes, the gaming state is shifted to a jackpot gaming state that is advantageous to the player. When the big hit gaming state is finished, the game shifts to the non-probable change state (normal game state). In the probability change state as described above, the probability of shifting to the big hit gaming state is improved relative to the normal gaming state.

  In addition, depending on the display mode in which these special symbols are derived and displayed, there may be a transition to the short time state after the end of the big hit gaming state. In this case, the short state is controlled so that the variable display time for special symbols and the like is shorter than the normal game state and the time for the blade member to be in the open state is longer. Increases the chance of entering a state.

  The game board liquid crystal display 2073 described above has a display area 2073A for displaying an image relating to the game. The game board liquid crystal display 2073 is disposed behind (on the back side of) the opening formed in the game board 1514.

It will be displayed in a predetermined manner.

  Also, on the liquid crystal display 2073 for the game board, the decorative symbols are variably displayed in accordance with the variable symbols special display on the special symbol display device 1161. When this decoration symbol derivation display is performed and the result of variable display of the special symbol in the special symbol display device 1161 is a specific display mode, the combination of the plurality of decoration symbols that are derived and displayed is a specific combination, The gaming state is shifted to a big hit gaming state advantageous to the player.

  In the present embodiment, the game board liquid crystal display 2073 including a liquid crystal display panel is used as a portion for displaying an image. However, the present invention is not limited to this, and other modes may be used. For example, CRT (Cathode Ray Tube), dot LED (Light Emitting Diode), segment LED, EL (Electronic Luminescent), plasma, etc. may be used.

  In the game area 1140 of the game board 1514 described above, various types of accessories are provided. An example of various types of accessory will be described below with reference to FIG. 6, but is not limited thereto.

  For example, a special symbol display device 1161 is provided above the center of the game area of the game board 1514.

As described above, when the game state is shifted to the big hit gaming state, the shutter 1145 is driven so as to be in an open state (first state) in which a game ball can be easily received.

  Further, the shutter 1145 is driven to the open state until a predetermined number of game balls pass through the special winning opening 1144 or until a predetermined time elapses. In other words, in the open state, when a condition for winning a predetermined number of game balls to the big prize opening 1144 or elapse of a predetermined time is satisfied, the big prize opening 1144 is closed in a state where the game balls cannot be received (second state). ). Subsequently, the shutter 1145 that has been changed from the open state to the closed state is again driven to the open state on condition that the upper limit number of rounds has not been reached.

  A starting port 1141A is provided above the shutter 1145. When a game ball wins at the start port 1141A, a special symbol game which will be described later is started, and the state shifts to a variable display state in which the special symbol is variably displayed. As the predetermined variable display start condition, in this embodiment, the main condition is that the game ball has won the start port 1141A (the game ball has passed through the start area). In other words, when a predetermined variable display start condition is satisfied (provided that the game ball has passed through the start area), the special symbol is variably displayed. In the embodiment, the predetermined variable display start condition is that a game ball has won the start opening 1141A, but the present invention is not limited to this.

  Also, if the game ball wins the start opening 1141A during the variable display of the special symbol in the special symbol game, the game ball wins the start opening 1141A until the special symbol being variable displayed is derived and displayed. Execution (start) of variable display of the special symbol based is suspended. That is, when the predetermined variable display execution condition is satisfied but the predetermined variable display start condition is not satisfied (when the predetermined variable display hold condition is satisfied), the predetermined variable display start condition is satisfied. The execution (start) of variable symbol special display is suspended. If the special symbol is derived and displayed in a state where the execution of the variable display of the special symbol is suspended, the execution of the variable display of the special symbol that is suspended is started.

  In addition, the special symbol variable display executed when the special symbol is derived and displayed is once. Further, an upper limit is set for the number of times the execution of the special symbol variable display is suspended. For example, the variable symbol variable display is suspended up to four times. Thus, when the variable display of the special symbol in the special symbol game is held, the special symbol hold display device 1163 displays the number of the hold.

  Similarly, in the normal symbol game, the execution (start) of the variable symbol display may be suspended, and when the variable symbol variable display is suspended, the normal symbol hold display device 1164 The hold number is displayed.

  In the present embodiment, the variable symbol special display and the normal symbol variable display are suspended with the upper limit being four times. However, the present invention is not limited to this, and other modes may be used. The variable display of the special symbol may be suspended with the upper limit of times or multiple times, and may be configured to be suspended without setting the upper limit. Of course, you may comprise so that the variable display of a special symbol may not be suspended.
