The present invention relates to a gaming machine represented by a pachinko machine.
A game machine such as a pachinko machine has a game board formed with a game area formed on the front side in which a shot game ball is guided and flows down, and a front frame that covers the board surface of the game board in a visible state through glass or the like from the front. And the like are generally provided. The members such as the front frame are usually pivotally supported at one side edge and are attached so as to be openable and closable in a hinged door manner. During various operations such as removing game balls caught on any part of the way or cleaning the board surface dirty by the passage of game balls, open the front frame and other members and work from the front (Hereinafter, openable and closable members that cover the game board from the front, such as the front frame, are also collectively referred to as “front door”.) (Japanese Patent Application Laid-Open No. 2004-8331)
Although the dimensions of gaming machines are standardized and constant, the area where nails are planted has expanded to the surrounding area due to the increase in size of liquid crystal devices arranged in the gaming area. The front door also extends to the position of the side edge where the front door is pivotally supported. For this reason, when the front door is opened to perform various operations on the board surface as described above, the front door becomes an obstacle near the side edge where the front door is pivotally supported, and work on the board surface is not performed. There is a problem that it is difficult.
In addition, there is also a problem that the front door inherently tends to be an obstacle to a player of a gaming machine adjacent to the opened side when the front door is opened.
In other words, the open front door is likely to be an obstacle not only to work on the board surface but also to games of an adjacent gaming machine, that is, inside and outside the gaming machine.
The present invention has been devised in view of such a problem, and an object of the present invention is to provide a gaming machine in which an open front door is unlikely to interfere with work on a board surface and games of an adjacent gaming machine.
Hereinafter, the best mode of the present invention will be described in detail with reference to the drawings. Here, a pachinko gaming machine (hereinafter, simply referred to as a “pachinko machine”) is exemplified as the gaming machine.

(Configuration of the pachinko machine front side)
FIG. 1 is a front view of the pachinko machine 10, and FIG. 2 is a perspective view of the pachinko machine 10. As shown in FIGS. 1 and 2, the pachinko machine 10 includes an outer frame 11 forming an outer shell of the pachinko machine 10, and an inner frame 12 supported on one side of the outer frame 11 so as to be openable and closable. ing. Hereinafter, the configurations of the outer frame 11 and the inner frame 12 will be individually described.

  The outer frame 11 is formed of a wooden plate as a whole in a rectangular shape, and each plate is assembled with a detachable fastener such as a small screw. The outer frame 11 may be made of resin or light metal such as aluminum. With this configuration, it is possible to reduce the weight of the pachinko machine.

  On the other hand, the opening / closing axis of the inner frame 12 is set so as to extend up and down on the opposite side (left side of the pachinko machine 10 in FIG. 1) from the front of the pachinko machine 10 where a handle (a game ball firing handle 18 described later) is installed. With this opening / closing axis as the axis, the inner frame 12 can be sufficiently opened forward. This configuration is based on the assumption that the opening / closing axis of the inner frame 12 is in the vertical direction on the handle installation side (the right side of the pachinko machine 10 in FIG. 1). This is because the head 18 and the like interfere with the adjacent pachinko machine or card unit (ball lending unit), and the inner frame 12 cannot be sufficiently opened. The inner frame 12 is made of a synthetic resin, specifically, an ABS (acrylonitrile-butadiene-styrene) resin. By doing so, the advantages of high viscosity, high impact resistance, and low-cost production can be obtained.

  The inner frame 12 is roughly divided into a lower plate unit 13 attached to the lowermost portion thereof, and a vertical portion on the left and right sides of the inner frame 12 in a range above the lower plate unit 13 as described later. It includes a front frame set 14 that is attached to be openable and closable about an opening / closing axis, a resin base (not shown), and a game board 30 described below that is attached to the rear side of the resin base. Each of these components will be described in detail below.

  The lower plate unit 13 is fixed to the inner frame 12 by fasteners such as screws. On the front side of the lower plate unit 13, a lower plate 15, a ball pulling lever 17, a game ball firing handle 18, an ashtray 22, and a sound output port 24 are provided. The lower plate 15 as a ball tray is provided substantially at the center of the lower plate unit 13 and serves to stop game balls discharged from the discharge port 16 when the upper plate described later becomes full. is there. The ball removing lever 17 is for removing a game ball in the lower plate 15. By moving the ball removing lever 17 to the left in FIG. 1, a predetermined portion of the bottom surface of the lower plate 15 is opened, The game balls stopped in the lower plate 15 can be discharged to the player's ball storage box (dollar box) through the opening on the bottom surface of the lower plate 15. The game ball firing handle 18 is disposed so as to protrude rightward from the lower plate 15 toward the near side. In response to an operation of the game ball firing handle 18 by the player, a game ball is hit by a game ball firing device provided with a firing solenoid toward a game board 30 described later. The sound output port 24 is an output port for outputting a sound from a speaker provided in the lower plate unit 13 or on the rear surface. The ashtray 22 is provided to the left of the lower plate 15. The right side of the ashtray 22 is supported by the lower plate 15 in a one-way manner so that the ashtray 22 rotates around the axis in the left-right direction (horizontal direction) (for example, rotates forward toward the front side).

  It should be noted that the lower plate unit 13 is mostly formed of ABS resin like the inner frame 12.

  On the other hand, an upper plate 19 as a tray for game balls is provided integrally with the front frame set 14 below the front frame set 14 (above the lower plate 15). The upper plate 19 is a ball tray for temporarily storing game balls and guiding them toward the game ball launching device 38 while aligning them in a line. In the conventional pachinko machine, a front decorative frame that can be opened and closed with respect to the inner frame is provided below the front frame set, and an upper plate is provided in the front decorative frame, but in this embodiment, the front decorative frame is omitted. The upper plate 19 is provided directly to the front frame set 14. Like the lower plate 15, the upper plate 19 has a configuration in which the surface layer is formed of a flame-retardant ABS resin. At the lower left of the upper plate 19, an effect button 79 for the player to perform an operation such as changing the background of the decorative symbol display device 42 is provided.

  In addition, light emitting means such as various lamps is provided around the front frame set 14 (for example, at a corner). These light-emitting means play a role of enhancing the effect during the game by controlling the light-emission mode such as lighting and blinking in accordance with a change in the game state during a jackpot game state or the like. For example, on the periphery of the window 101, an annular illuminated portion 102 having a built-in light emitting means such as an LED is provided symmetrically, and lights or blinks at the time of the jackpot game state, thereby indicating that the player is in the jackpot game state. This is a configuration for notifying.

  A ball lending operation unit 120 is provided below the window 101. The ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. When the ball lending operation unit 120 is operated in a state in which bills, cards, and the like are inserted into a card unit (ball lending unit) (not shown) arranged on the side of the pachinko machine 10, the lending of game balls is performed according to the operation. Done. The ball lending button 121 is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is supplied to the upper plate 19 as long as there is a remaining amount on the card or the like. Is done. The return button 122 is operated when requesting the return of a card or the like inserted in the card unit. The frequency display unit 123 displays remaining amount information such as cards. In a pachinko machine in which game balls are lent directly from the ball lending device to the upper plate without the intervention of a card unit, a so-called cash machine, the ball lending operation unit 120 becomes unnecessary. Therefore, a decoration seal or the like is attached to the installation portion of the ball lending operation unit 120. Thus, the ball-lending operation unit can be shared between the pachinko machine using the card unit and the cash machine.

  Next, the configuration of the game board 30 will be described with reference to FIGS. FIG. 3 is a front view showing the configuration of the game board 30, and FIG. 4 is a view schematically showing the vicinity of the entrance 61 of the accommodation section. The gaming board 30 has a general winning opening 31, a variable winning device 32, a first starting opening 33 composed of an upper starting opening 33a and a lower starting opening 33b (composed of an operating chucker 33b), and a second starting opening 34 (through gate). ), A special symbol display device 38, a normal symbol display device 41, and a variable display device unit 35 including a decorative symbol display device 42. The general winning opening 31, the variable winning device 32, the first starting opening 33, the second starting opening 34, the variable display device unit 35, etc. are respectively provided in the through holes formed by the router processing in the game board 30. The game board 30 is attached from the front side with wood screws or the like. At the entrance of the lower starting port 33b, a pair of opening and closing blades 60 are provided as shown in FIG. 4, and an open position for guiding the game ball and a closing position in which the game ball becomes difficult to enter the lower starting port 33b. Can take position. The opening and closing blade 60 is driven by a solenoid SL1 disposed on the back side of the game board 30. In addition, below the lower starting port 33b, an entrance 61 of the storage unit is arranged. The entrance 61 of the storage section will be described later. An entrance ball detection switch SW1 is provided in the entrance 61 of the accommodation section.

  A game ball enters the above-described general winning opening 31, the variable winning device 32, and the first starting opening 33, and the incoming ball is detected by a detection switch (a winning opening switch, a count switch, an operating port switch, etc.) described later. A predetermined number of prize balls are paid out to the upper plate 19 (or the lower plate 15) based on the output of the detection switch. In addition, the game board 30 is provided with an out port 36, so that game balls that have not entered the various prize devices or the like are guided to a ball discharge path (not shown) through the out port 36. It has become. On the game board 30, a large number of nails are planted for appropriately dispersing and adjusting the falling direction of the game ball, and various members (accessories) are provided.

  The special symbol display device 38 variably displays a special symbol as identification information with a prize at the first starting opening 33 as a trigger, and the decorative symbol display device 42 variably changes a decorative symbol corresponding to the special symbol variable display. The normal symbol display device 41 displays the normal symbol in a variable manner by passing through the second starting port 34 as a trigger.

  The special symbol display device 38 is composed of two-color LEDs 38a and 38b, and the display content is controlled by a main control device 261 to be described later. Each of the LEDs 38a and 38b is adapted to perform a variable display of, for example, red and green.

  The decorative symbol display device 42 is configured as a liquid crystal display device, and the display content is controlled by a display control device described later. On the decorative symbol display device 42, symbols as identification information are displayed at, for example, three places: upper, middle, and lower. These symbols are scrolled and variably displayed on the decorative symbol display device 42. In this embodiment, the decorative design display device 42 (liquid crystal display device) includes a large liquid crystal display of, for example, a 10-inch or 12-inch size.

  The ordinary symbol display device 41 includes ordinary symbol lamps 41a and 41b. In this embodiment, the lamp 41a for a normal symbol is provided, for example, above both sides of the display of the decorative symbol display device 42, and has an "O" shape in appearance, while the lamp 41b for an ordinary symbol is , Is provided adjacent to the upper right side of the lamp 41a, and its external shape is an “X” shape. In the normal symbol display device 41, for example, each time the game ball passes through the second starting port 34, the display symbol (ordinary symbol) by the lamps 41a and 41b fluctuates. Specifically, the lamps 41a and 41b alternately light up. When the operation is stopped by the lamp 41a, the lower starting port 33b of the first starting port 33 is operated (opened) for a predetermined time. The number of times that the game ball has passed through the second starting port 34 is held up to a maximum of four times, and the held number of times is lit on the holding lamp 801a. In addition, the lamps 41 a and 41 b may be a plurality of display units that are variably displayed on a part of the decorative symbol display device 42.

  The variable winning device 32 is normally in a closed state in which game balls cannot be won or hard to win, and is repeatedly operated between an open state in which the game balls can easily win and a normal closed state in a big hit. However, the specific configuration will be described later. Briefly, when the special symbol display device 38 is in a specific display mode (when the fixed symbol after the decoration symbol display device 42 is stopped is a combination of a specific symbol set in advance), the special game state is set. Occurs. Then, the variable winning device 32 enters a ball receiving state, and allows winning of a game ball. Specifically, the elapse of a predetermined time (for example, 30 seconds) or a predetermined number (for example, 10) of winnings is defined as one round, and the receiving state of the variable winning device 32 is repeatedly opened a predetermined number of times. The number of times the game ball has passed through the first starting port 33 is held up to a maximum of four times, and the number of times held is lit on the hold lamp 800a. Note that the holding lamp 800a may be configured to be variably displayed on a part of the decorative symbol display device 42 or the like.

  The game board 30 is provided with a rail unit 50 for guiding a game ball fired from the game ball launching device to the upper part of the game board 30, and is fired by a rotating operation of the game ball firing handle 18. The game ball is guided to a predetermined game area through the rail unit 50. The rail unit 50 is made of a ring-shaped metal plate, and has an inner rail 51 and an outer rail 52 that are integrally formed inside and outside. At the rear edge of the inner rail 51 and the outer rail 52 (the edge facing the game board 30), studs 56 are provided at a plurality of locations at predetermined intervals, and the inner rail 51 and the outer rail 52 are The studs 56 are attached to the game board 30 so as to strike. The inner rail 51 is formed in a substantially annular shape except for about an upper one-fourth, and an outer rail 52 is formed so that a part (mainly a left side) faces the inner rail 51. In such a case, a guide rail is constituted by the inner rail 51 and the outer rail 52, and a ball guide passage is formed by a portion (the left portion as viewed) where the rails 51 and 52 are parallel to each other at a predetermined interval. The ball guide passage is formed in a groove shape having an abutting surface with the game board 30, that is, a groove shape having an open front side.

  A return ball preventing member 53 is attached to a tip portion (upper left portion in FIG. 4) of the inner rail 51. This prevents a situation in which a game ball once guided from the ball guide passage between the inner rail 51 and the outer rail 52 to the upper portion of the game board 30 returns to the ball guide passage again. I have.

  Note that the game area is formed in a substantially circular shape by the inner peripheral portion (inner and outer rails) of the rail unit 50 and the oblique side of the main display unit 371. In the present embodiment, the game area is particularly formed on the board of the game board 30. Game area is much larger than before.

(Back view of pachinko machine)
Next, the configuration of the back of the pachinko machine 10 will be described. FIG. 5 is a rear view of the pachinko machine 10.

  First, an overall outline of the rear configuration of the pachinko machine 10 will be described. On the back side of the pachinko machine 10 (actually, on the back side of the inner frame 12 and the game board 30), various control boards are arranged so as to be arranged vertically and horizontally, or to be stacked back and forth. A game ball supply device (payout mechanism) for supplying game balls, a resin protective cover, and the like are attached. In the present embodiment, various control boards are separately mounted on two mounts to form two control board units, and these control board units are individually mounted on the inner frame 12 or the back surface of the game board 30. . In this case, the main control board (device), the power supply monitoring board (device), and the sub-control board (device) are mounted on one mounting base to form a unit, and the payout control board (device) and the emission control board (device) ) And a power supply board (apparatus) are mounted on the other mount to form a unit. Here, for convenience, the former unit is referred to as a “first control board unit 201”, and the latter unit is referred to as a “second control board unit 202”.

  Further, the dispensing mechanism and the protective cover are also integrated as one unit, and the resin portion is generally called a back pack. Therefore, the unit is herein referred to as a “back pack unit 203”. The detailed configuration of each of the units 201 to 203 will be described later.

  The first control board unit 201, the second control board unit 202, and the back pack unit 203 are configured to be detachable in units without using any tool or the like. Is provided so that the inner frame 12 or the back surface of the game board 30 can be opened and closed. This is also a device for making it possible to easily check a hidden configuration or the like even when the units 201 to 203 and other components are arranged one above the other.

  The above-described first control board unit 201 includes a main control board for controlling the progress of the game, a power supply monitoring board for monitoring power supply, a display control of the decorative symbol display device 42 and an audio lamp according to instructions from the main control board. And a sub-control board for controlling. The main control board and the power supply monitoring board are housed in a board box 263 made of a transparent resin material or the like. The board box 263 includes a substantially rectangular parallelepiped box base and a box cover that covers an opening of the box base. The box base and the box cover are connected to each other by a sealing unit so that the board base cannot be opened. Box 263 is sealed.

  The sealing unit may have any configuration as long as the box base and the box cover are connected so that the box base cannot be opened. The sealing process by the sealing unit prevents unauthorized opening after the sealing. Even if an unauthorized opening is performed, such a situation can be detected early and easily.

  Next, the second control board unit 202 has a payout control board, a firing control board, a power supply board, and a card unit connection board. The payout control board controls the payout of prize balls and rental balls, the launch control board controls the firing solenoid according to the operation of the game ball firing handle 18 by the player, and the power supply board requires various control devices and the like. A predetermined power supply voltage is generated and output. The card unit connection board is electrically connected to a ball lending operation unit 120 (see FIG. 1) on the front of the pachinko machine and a card unit (not shown), and takes in a ball lending operation command from the player and controls the payout. Output to the substrate. In a cash machine in which game balls are directly rented to the upper plate from a ball rental device or the like without the intervention of a card unit, the card unit connection board is unnecessary.

  The dispensing control board is housed in a dispensing control board case 280 made of a transparent resin material or the like, and the power supply board is housed in a power supply board case 281 made of a transparent resin material or the like. The card unit connection board is housed in a card unit connection board case 314 made of a transparent resin material or the like, and the emission control board is housed in a firing control board case (not shown) made of a transparent resin material or the like. In particular, in the dispensing control board, as in the case of the main control board described above, the box base and the box cover constituting the board case (enclosing means) are unopenably connected by a sealing unit (sealing means), so that the board box is not opened. Is sealed.

  The dispensing control board is electrically connected to the state return switch 321. For example, when the state return switch 321 is pressed down at the time of a dispensing error such as a clogged ball in the dispensing motor unit, the dispensing motor slowly rotates. The ball is rotated to eliminate clogging of the ball (return to a normal state).

  Next, the configuration of the back pack unit 203 will be described. The back pack unit 203 integrates a back pack 351 formed of resin and a payout mechanism 352 for game balls.

  The back pack 351 is integrally molded of, for example, an ABS resin, and has a substantially flat base portion 353 and a protective cover portion 354 that projects to the rear of the pachinko machine and has a substantially rectangular parallelepiped shape. The protective cover portion 354 has a shape in which the left and right side surfaces and the upper surface are closed and only the lower surface is opened, and has at least a size sufficient to surround the electric accessory unit (center accessory). ). A large number of ventilation holes 354a are provided on the back surface of the protective cover 354.

The power failure monitoring circuit 542 monitors a DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 541, and determines that a power failure (power interruption) has occurred if this voltage falls below 22 volts. The power outage signal SG1 is output to the main control device 261 and the payout control device 311. Based on the output of the power failure signal SG1, the main control device 261 and the payout control device 311 recognize the occurrence of the power failure and execute the NMI interrupt process. In addition, even after the DC stable voltage of 24 volts becomes less than 22 volts, the power supply unit 541 outputs the voltage of 5 volts, which is the drive voltage of the control system, for a time sufficient for executing the NMI interrupt processing. Is maintained at a normal value. Therefore, main controller 261 and payout controller 311 can normally execute and complete the NMI interrupt processing.

  The reset circuit 544 is a circuit that outputs a reset signal to initialize the main control device 261, the payout control device 311, the sub control device 262, and the display control device 45. The reset signal from the reset circuit 544 is directly supplied to the main control device 261, but is supplied to the payout control device 311, the sub control device 262, and the display control device 45 via the power supply device 313. Is to be given.

  Here, the display contents of the special symbol display device 38, the ordinary symbol display device 41, and the decorative symbol display device 42 will be described. In the pachinko machine 10 of the present embodiment, a special symbol displayed on the special symbol display device 38 as a symbol for indicating occurrence of a big hit to the player and a decorative symbol displayed on the decorative symbol display device 42 are used. Two types are provided. The decorative design is a design that fluctuates in synchronization with the special design, starts to fluctuate at the same time (or almost at the same time) as the special design starts to change, and at the same time as the special design stops changing (or almost at the same time). 2) Stop the fluctuation. The decorative pattern is provided to provide the player with a variety of display effects to provide the player with a game that is hard to get tired of.

  First, the display contents of the special symbol display device 38 will be described. The change display of the special symbol is expressed by a change in the lighting pattern such as a color change (a change between red and green) and blinking of the special symbol display lamps 38a and 38b. The variable display of the special symbol is started based on the winning of the game ball into the starting port 33, and the variable display of the special symbol is simultaneously stopped after a predetermined time. After the stop, when the special symbols are aligned, that is, when the special symbol display lamps 38a, 38b are in the lighting state of the same color, a big hit occurs. When the special symbols are not aligned when the variable display is stopped, that is, When the special symbol display lamps 38a and 38b are in a different color lighting state, they are out of order, and the variable display is performed again based on the winning in the starting opening 33. The number of times that the game ball has won the starting port 33 is retained up to a maximum of four times, and the retained number of times is illuminated and displayed on the reservation lamp 800a of the special symbol reservation display device 800. In this embodiment, if the special symbol display lamps 38a and 38b are both lit in red when the variable display is stopped, the special symbol display lamps 38a and 38b are regarded as a specific symbol (probability variation symbol). If it is in the green lighting state, it is regarded as a non-specific symbol (non-probability variable symbol).

  Next, the display contents of the decorative symbol display device 42 will be described. On the display screen of the decorative symbol display device 42, for example, three decorative symbol columns Z1 to Z3 are displayed in three display areas divided into upper, middle, and lower rows. These decorative symbol columns Z1 to Z3 are scroll-displayed from right to left. The decorative symbol is composed of a main symbol consisting of, for example, numbers "1" to "9", and a sub symbol smaller than the main symbol, and the main symbol and the sub symbol form a symbol row of the decorative symbol. In each symbol row formed by the decorative symbols, the main symbols are arranged in ascending or descending order of numbers, and sub symbols are arranged between the main symbols. When a winning in the starting opening 33, that is, a starting prize is generated, the fluctuating display of the decorative symbol is performed, the fluctuating display is stopped after a lapse of a predetermined time according to the fluctuating pattern, and the decorative symbol display device 42 displays 3 × 3. Are displayed as the display results. In the variable display that has won the jackpot lottery, the display control device 45 controls the three main symbols to be stopped in a vertical or diagonal straight line among the nine decorative symbols, so that the player is stopped. A jackpot occurrence is indicated. On the other hand, in the variable display out of the jackpot lottery, the display control device 45 controls the three main symbols so as not to stop in any of the vertical or diagonal directions among the nine decorative symbols. The outbreak is indicated to the person.

  Next, the display contents of the ordinary symbol display device 41 will be described. The fluctuation display of the ordinary symbol is expressed by alternately lighting the ordinary symbol display lamp 41a (appearance is O shape) and the ordinary symbol display lamp 41b (appearance is X shape). The variation display of the ordinary symbol is started on condition that the game ball passes through the second starting port 34, and after a predetermined time, the variation display of the ordinary symbol is stopped. Then, the first starting port 33 is configured to be operated (opened) for a predetermined time when stopped by the display lamp 41a. The number of times the game ball has passed through the second starting port 34 is held up to a maximum of four times, and the number of times held is normally lit and displayed on the holding lamp 801a of the symbol holding display device 801.

  Next, the operation of the pachinko machine 10 configured as described above will be described. In the present embodiment, the MPU 501 in the main control device 261 performs a jackpot lottery and the setting of the symbol display of the special symbol display device 38 using various kinds of counter information at the time of the game. More specifically, it includes a counter group related to a special symbol and a counter group related to a normal symbol. First, a group of counters related to special symbols will be described. As a group of counters related to the special symbol, the jackpot random number counter C1 used for the jackpot lottery, the jackpot symbol counter C2 used for selecting the jackpot symbol of the special symbol display device 38, and the special symbol display device 38 deviate and change. The stop pattern selection counter C3 used for selection of a stop pattern at the time (corresponding to a reach lottery of determining whether to reach or completely deviate in the case of fluctuation of decorative symbols) and an initial value of the jackpot random number counter C1 It has an initial value random number counter CINI1 and fluctuation type counters CS1 to CS3 for determining the type used for selecting a fluctuation pattern.

  Here, the fluctuation pattern means each pattern (form) in a case where a pattern having a common characteristic of the fluctuation display is classified.

  Each of the counters C1 to C3, CINI1, and CS1 to CS3 is a loop counter in which 1 is added to the previous value each time it is updated, and returns to 0 after reaching the maximum value. Each counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a reserved ball storage area 700 composed of one execution area and four reserved areas (reserved first to fourth areas). In each of these areas, a game ball to the starting port 33 is provided. , The respective values of the jackpot random number counter C1, the jackpot symbol counter C2, and the stop pattern selection counter C3 are stored, respectively.

Next, the specific contents of each counter will be described in detail.
The jackpot random number counter C1 is configured to be incremented by one in order within a range of, for example, 0 to 738, and to return to 0 after reaching the maximum value (that is, 738). In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI1 at that time is read as the initial value of the jackpot random number counter C1. Note that the random number initial value counter CINI1 is configured as a loop counter that is updated in the same range as the jackpot random number counter C1 (value = 0 to 738), is updated once every timer interrupt, and is executed during the remaining time of the normal processing. Is updated repeatedly. The jackpot random number counter C1 is updated periodically (once for each timer interrupt in this embodiment), and is stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball wins the starting port 33. The number of random hit values at the time of low probability and the high probability are set at two types. The number of random numbers at the time of low probability is two, and the value is “373,727”. Yes, the number of random numbers that will be a big hit at high probability is 14, and the value is "59, 109, 163, 211, 263, 317, 367, 421, 479, 523, 577, 631, 683, 733". is there. In addition, the high probability time means that a special symbol combination is a predetermined probability variation symbol combination of specific symbols (in the present embodiment, the specific symbol display lamps 38a and 38b are both lit in green) and a big hit is achieved. The state in which the subsequent jackpot probability is increased as the added value, that is, the time of so-called probable change, and the normal time (low probability) is not such a probable change state (in the present embodiment, the specific symbol display lamps 38a and 38b are (When both light up in red).

  The big hit symbol counter C2 is for determining a special symbol at the time of a big hit when the change of the special symbol in the special symbol display device 38 is stopped. For example, the symbol is added one by one in a range of 0 to 4, and the maximum value (ie, 4 ), And returns to 0 after reaching. For example, when the value of the jackpot symbol counter C2 is "0" or "1", the special symbol display lamps 38a and 38b are both stopped in green, and the combination of the special symbols is non-specific symbol (normally). Jackpot pattern).

  When the value of the jackpot symbol counter C2 is "2", "3", or "4", the special symbol display lamps 38a and 38b are both stopped in red, and the combination of the special symbols (in this case, the specific symbol ( (Probability variation symbol).

  The jackpot symbol counter C2 is updated periodically (in this embodiment, once for each timer interrupt), and is stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball wins the starting port 33.

  The stop pattern selection counter C3 is configured to be incremented by one, for example, in the range of 0 to 238, and return to 0 after reaching the maximum value (that is, 238). In the present embodiment, the special symbol change display is configured to be expressed by the two display lamps 38a and 38b. Therefore, in the case of the special symbol, there is no concept of reach, and the stop pattern corresponding to reach is changed to the stop pattern. It is determined by the selection counter C3. On the other hand, in the case of a decorative symbol, there is reach because three decorative symbols stop. Therefore, in the case of the decorative symbol, the reach lottery is determined by the stop pattern selection counter C3. In other words, in the case of a decorative symbol, the final stop symbol is shifted one position before and after the reach symbol after reaching, and the "rear-and-aft reach", and the final stop symbol after reach has occurred, except for the front and rear of the reach symbol. It is decided to draw lots of “reach other than out of front and rear” to stop and “complete out of reach” where no reach occurs. For example, the stop pattern selection counter C3 = 0 to 201 corresponds to complete deviation, the stop pattern selection counter C3 = 202 to 208 corresponds to forward and backward reach, and the stop pattern selection counter C3 = 209 to 238 corresponds to reach other than forward and backward. Applicable.

  Here, the “reach” means that after the decorative symbol displayed on the display screen of the decorative symbol display device 42 starts the variable display, the combination of the symbols stopped first is the same symbol (in the decorative symbol having a plurality of effective lines, The combination of the jackpot symbols, which suggests to the player that the jackpot will be achieved depending on the display result of the symbol that is the same symbol on any of the activated lines) and meets the condition of the jackpot, and the variable display is continued. Is expected to be expected by the player, and is a kind of entertainment effect. The entertaining effect means that a predetermined symbol represented by reach is displayed on the display screen of the decorative symbol display device 42 during the variable display, a specific sound is output from a speaker, or a vibration motor is used. This is an effect of causing the player to expect that the display result after the variable display will be a big hit, with the unusual mode being accompanied by the variable display, such as vibrating the game ball firing handle 18.

  The stop pattern selection counter C3 is updated periodically (once for each timer interrupt in this embodiment), and is stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball wins the starting port 33.

The variation type counter CS1 is configured to be incremented by one, for example, in the range of 0 to 198, and to return to 0 after reaching the maximum value (that is, 198). The fluctuation type counter CS2 is configured to be incremented by one, for example, in the range of 0 to 240, and to return to 0 after reaching the maximum value (that is, 240). The variation type counter CS3 is configured to be incremented by one, for example, in the range of 0 to 162, and to return to 0 after reaching the maximum value (that is, 162).
A rough symbol variation mode such as a reach type such as a normal reach, a super reach, or a premium reach is determined by the variation type counter CS1, and a finer symbol such as a normal reach A or a normal reach B is determined by the variation type counter CS2. The variation mode is determined, and addition / subtraction of the variation time in the case of the slip stop variation is determined by the variation type counter CS2. Therefore, by combining these variation type counters CS1 to CS3, a wide variety of variation patterns can be easily realized.

  The counters CS1 to CS3 are updated once each time a normal process described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of the counters CS1 to CS3 are obtained when determining the variation pattern at the start of the variation of the special symbol by the special symbol display device 38 and the decoration symbol by the decorative symbol display device 42.

  Next, a group of counters related to the ordinary symbols will be described. The counter group related to the normal symbol includes a winning random number counter C4 used for winning lottery and an initial value random number counter CINI2 used for setting an initial value of the winning random number counter C4.

  The hit random number counter C4 is a loop counter in which 1 is added to the previous value every time it is updated, and returns to 0 after reaching the maximum value. The counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a reserved ball storage area 701 composed of one execution area and four reserved areas (reserved first to fourth areas). The value of the random number counter C4 is stored in accordance with the passing of the game ball.

  Next, the specific contents of the hit random number counter C4 and the initial value random number CINI2 will be described in detail. The hit random number counter C4 is configured to be incremented by one, for example, in the range of 0 to 250, and to return to 0 after reaching the maximum value (ie, 250). When the hit random number counter C4 makes one round, the value of the hit initial random number counter CINI2 at that time is read as the initial value of the hit random number counter C4. Note that the initial value random number counter CINI2 is configured as a loop counter that is updated in the same range as the random number counter C4 (value = 0 to 250), is updated once every timer interrupt, and is executed within the remaining time of the normal processing. Is updated repeatedly. The hit random number counter C4 is updated periodically (once every timer interrupt in this embodiment), and is stored in the reserved ball storage area 701 of the RAM 503 at the timing when the game ball passes through the second starting port 34. The number of random numbers to be a hit of the hit random number counter C4 is 149, and the value is “5 to 153”.

  Note that the size and range of each counter are merely examples, and can be arbitrarily changed. However, if emphasis is placed on irregularities, the sizes of the jackpot random number counter C1, the stop pattern selection counter C3, the random number counter C4, and the variation type counters CS1 to CS3 are all different prime numbers, and are values that are not synchronized in any case. It is desirable to keep.

The details of each control process executed by the MPU 501 in the main control device 261 are omitted here.
However, in summary, as described above, the winning in the starting opening 33 causes the main control device 261 to perform a winning / non-winning lottery with a predetermined probability, and at the time of winning, shifts to a special game state.

Thereby, the support member 83 to which the movable shaft member 82 is fixed is held between the casing 81 and the mechanism housing portion 14H so as to be slidable in the left-right direction. At this time, the support member 83 is attached so as to fit the compression coil spring 86 into the groove 83G in a posture facing left and right, whereby the support member 83 is moved rightward with respect to the left side surface of the mechanism housing portion 14H. Is to be energized.

  As shown in FIGS. 9 and 10, the upper left pivot 70C is configured to be symmetrical with the upper right pivot 70A, and the lower right pivot 70B is basically configured similarly to the upper right pivot 70A. Therefore, the description of the upper left shaft support 70C and the lower right shaft support 70B is omitted. However, in the lower right shaft support 70B, as shown in FIGS. 39 and 40, two left and right cutouts are formed in the horizontal piece of the bracket 74B, and the left cutout is similar to the tube 75A of the upper right support 70A. A tube 75B having the same structure as that described above is disposed in the same structure, and the second wire 76B is inserted therethrough. The notch on the right side has the same structure as the end member 75E of the tube 75A in the upper right shaft support 70A. The guide member 87 is fitted, and the first wire 76A of the upper right shaft support 70A is inserted therethrough. The lower left shaft support 70D is configured to be symmetrical with the lower right shaft support 70B, and a description thereof will be omitted.

  As shown in FIGS. 39 and 40, a first right pulley 88A whose axial direction is directed forward and backward is supported directly above the right slider 68R, and the first wire 76A is guided by the first right pulley 88A. Then, the hook piece 681R is inserted into a slit of the hook piece 681R of the right slider 68R, and a fastener is fixed to a tip of the hook piece 681R so as to be hooked on the inner surface (lower surface) of the hook piece 681R. The second wire 76B is inserted into the slit of the hook piece 681R of the right slider 68R without being guided by the pulley, and is hooked on the inner surface (lower surface) of the hook piece 681R by a fastener fixed to the tip. I have.

  As shown in FIGS. 12, 13 and the like, the fourth right pulley 88D just above the hook piece 681L of the left slider 68L and the left side (right side in FIGS. 12 and 13) in the same manner as the first right pulley 88A. And the third right pulley 88C are pivotally supported, and below the lower left pivot support 70D on the rear side surface of the inner frame 12, at the same height position as the fourth right pulley 88D and the third right pulley 88C, and at the upper right of each other. A fourth left pulley 89D and a third left pulley 89C are pivotally supported at two locations aligned diagonally at the lower left. The third wire 76C and the fourth wire 76D have one ends hooked on the hook pieces 681L of the left slider 68L in the same manner as the first wire 76A and the second wire 76B, and the third right pulley 88C and the fourth The right and left pulleys 88D and 89D respectively extend to the left, the third and fourth left pulleys 89D and 89D respectively extend upward and have the other ends of the first and second wires 76A and 76B, respectively. In the same manner as above, it is fixed to the upper left shaft support 70C and the lower left shaft support 70D.

  In the above configuration, an operation mechanism (key operation mechanism) including the cylinder lock 62, the rotor 67, etc., the right and left sliders 68R, 68L, the first to fourth wires 76A to 76D, the first, A transmission mechanism including the third and fourth right pulleys 88A, 88C, 88D, the third and fourth left pulleys 89C, 89D, and the like, and a configuration including the movable member 72, the base material 73, the rotating shaft 82S, and the like. Are linked (linked) in such a manner that they can be linked in this order, and the power generated by the operation of the operating mechanism (key operating mechanism) is transmitted via the transmission mechanism to change the state of the supporting mechanism in the supporting mechanism. It is configured to be driven to be released.

Hereinafter, the opening and closing operations of the inner frame 12 and the front frame set 14 will be sequentially described.
A. Closed state As described above, when the inner frame 12 is closed with respect to the outer frame 11, the hook 65H of the engagement piece 65 is engaged with the metal fitting of the outer frame 11, whereby the outer frame 11 is closed. The inner frame 12 is restrained in a closed state. On the other hand, when the front frame set 14 is fitted into the inner frame 12, the front frame set 14 is closed with respect to the inner frame 12 by the upper right shaft support 70A, the lower right shaft support 70B, the upper left shaft support 70C, and the lower left shaft support 70D. Be bound by the state.

  Specifically, taking the case of the upper right pivot support 70A as a representative example, as shown in FIG. 45, the operating piece 72F of the movable member 72 and the fixed operating piece of the base material 73 in the bearing-side mechanism 71R on the inner frame 12 side. 73F, as described above, is normally held together by the urging force of the compression coil spring 78 and held in a closed posture. In this closed posture, the distal ends of the operating piece 72F and the fixed operating piece 73F are integrally formed. 45, the inner side (rear side) is recessed in an approximately valley shape from the both sides to the center from the center in plan view. On the other hand, the shaft-side mechanism 71S on the front frame set 14 side is indicated by an arrow in FIG. As shown in A11, the rotating shaft 82S of the movable shaft member 82 enters the recessed portions of the operating piece 72F and the fixed operating piece 73F, and the operating piece opposes the urging force of the compression coil spring 78. Press 72F Continue to enter while expanding. When the rotating shaft 82S reaches the position of the shaft fitting notch 72R of the movable member 72 and the position of the shaft fitting notch 73R of the base member 73 and fits into these shaft fitting notches 72R, 73R, the operating piece is actuated by the urging force of the compression coil spring 78. 72F is again fitted with the fixed operation piece 73F and returns to the closed posture. Thus, the rotating shaft 82S is surrounded by the shaft fitting notch 72R of the movable member 72 and the shaft fitting notch 73R of the base member 73, and is held in this posture by the urging force of the compression coil spring 78. That is, the urging force of the compression coil spring 78 holds the shaft fitting notch 72R of the movable member 72 and the shaft fitting notch 73R of the base material 73 integrally so as to form a circular shaft insertion hole. The rotating shaft 82S is held in a posture supported by the hole. The lower right shaft support 70B, the upper left shaft support 70C, and the lower left shaft support 70D are each held in a posture in which the rotary shaft is supported by the shaft insertion hole in the same manner as in the case of the upper right shaft support 70A. As shown in FIG. 13, the front frame set 14 is pivotally supported by the inner frame 12 at four corners and is restrained in a closed state.

B. Opening of the inner frame 12 As described above, the inner frame 12 is closed regardless of whether the inner frame 12 and the front frame set 14 are closed or only the front frame set 14 is opened by an operation described later. Is closed with respect to the outer frame 11, the key K1 is inserted into the cylinder lock 62 as shown in FIG. 35, and the cylinder lock 62 is moved rearward against the urging force of the compression coil spring 62S as shown by an arrow A12. 36, the key K1 is rotated clockwise (counterclockwise in FIG. 36) as shown by an arrow A13 in FIG. As a result, the rotor 67 rotates clockwise at the position where the rotor 67 is pushed backward, whereby the engagement projection 67E engages with the engagement notch 65R of the engagement piece 65, and an arrow shown in FIG. The engagement notch 65R is pushed down as indicated by A14, whereby the engagement piece 65 is pushed down against the urging force of the tension coil spring 66 as shown in FIGS. When the engagement piece 65 is pushed down in this manner, the hook portions 65E of the hooks 65H are disengaged downward from the receiving fittings, whereby the closed state of the inner frame 12 with respect to the outer frame 11 is released. Can be opened by pulling the right side of the front.

C. Opening the front frame set to the left As described above, both the inner frame 12 and the front frame set 14 are closed or only the inner frame 12 is opened, that is, the front frame set 14 is opened regardless of the open / closed state of the inner frame 12. 12, the key K1 is inserted into the cylinder lock 62, and the cylinder lock 62 is pushed forward by the urging force of the compression coil spring 62S without being pushed in, as shown in FIG. As shown by an arrow A15 in FIG. 38, the key K1 is rotated clockwise (counterclockwise in FIG. 38). As a result, the rotor 67 rotates clockwise at the front position where the rotor 67 is not pushed rearward, and accordingly, the engagement protrusion 67E engages with the notch 682R of the right slider 68R. 26A and 26B, the right notch 682R is pushed down as shown in FIG. 26 and FIG.

  When the right slider 68R is pressed down, both the first wire 76A and the second wire 76B hooked on the hook piece 681R are pulled down. When the first wire 76A is pulled down, as shown in FIGS. 43 and 44, the hook piece 72E hooked on the tip of the first wire 76A is pulled backward against the urging force of the compression coil spring 78. As a result, the movable member 72 is rotated clockwise in plan view as shown by an arrow A17 in FIG. When the movable member 72 rotates in this manner, the operating piece 72F rotates so as to separate from the fixed operating piece 73F of the base material 73 and expands. With this rotation, the front end edge of the pressing piece 72P of the movable member 72 is moved. As shown by an arrow A18 in the figure, the rotary shaft 82S abuts against the rotary shaft 82S and slightly pushes the rotary shaft 82S leftward away from the fixed operating piece 73F against the urging force of the compression coil spring 86. Thereby, the rotating shaft 82S is detached from the shaft fitting notch 73R of the base material 73, while the front end of the pressing piece 72P is at the base end side (the base 72B side) of the shaft fitting notch 72R in the movable member 72 as described above. ) Since it is shaped so as to gradually expand from the end position to the outside of the circumferential direction of the shaft fitting notch 72R, when the movable member 72 rotates as described above, the distal end portion of the operating piece 72F and the pressing piece 72P. Is positioned such that it can be opened forward, so that the rotation shaft 82S is not restricted from moving forward (hereinafter, also referred to as an “unrestricted state”). On the other hand, at the same time, when the second wire 76B is pulled down, the lower right shaft support 70B is similarly unconstrained.

  As described above, the upper right shaft support 70A and the lower right shaft support 70B are in the non-restrained state, while the upper left shaft support 70C and the lower left shaft support 70D are continuously restrained in the posture supported by the shaft. When the right side of the front frame set 14 is pulled toward the user in this state, the front frame set 14 is opened around the rotation axes of the upper left shaft support 70C and the lower left shaft support 70D as shown in FIGS. Opening to the left (also referred to herein as "left opening") becomes possible. As shown in the figure, when the front frame set 14 is rotated to the left by about 90 °, the left side of the set abuts against the inner frame 12, and further rotation is difficult. That is, the position at which the front frame set 14 is rotated leftward by about 90 ° is the leftward open limit position.

D. Opening the front frame set to the right As described above, both the inner frame 12 and the front frame set 14 are closed or only the inner frame 12 is opened, that is, the front frame set 14 is opened regardless of the open / closed state of the inner frame 12. 12, the key K1 is inserted into the cylinder lock 62, and the cylinder lock 62 is pushed forward by the urging force of the compression coil spring 62S without being pushed in, as shown in FIG. As shown by an arrow A19 in FIG. 38, the key K1 is rotated counterclockwise (in FIG. 38, clockwise). As a result, the rotor 67 rotates counterclockwise at a front position where the rotor 67 is not pushed rearward, and accordingly, the engaging projection 67E engages with the latching notch 682L of the left slider 68L and rotates. The latching notch 682L is pushed down as shown by an arrow A20 in the figure, whereby the left slider 68L is pushed down as shown in FIGS.

  When the left slider 68L is pushed down, both the third wire 76C and the fourth wire 76D hooked on the hook piece 681L are pulled down, and accordingly, the above-described upper right shaft support 70A and lower right shaft support 70B are not restrained. In the same manner as in the state, the upper left shaft support 70C and the lower left shaft support 70D are driven to be in the non-restrained state. On the other hand, in the upper right pivot support 70A and the lower right pivot support 70B, since the rotating shaft is continuously restrained by the supported posture, if the left side of the front frame set 14 is pulled forward in this state, FIG. 32, it is possible to open the front frame set 14 around the rotation axis of the upper right shaft support 70A and the lower right shaft support 70B and open it to the right like a door (also referred to as "right open" in this specification). It becomes. As shown in the figure, when the front frame set 14 is turned to the right by about 90 °, the right side surface thereof abuts against the inner frame 12, and further turning is difficult. That is, the position at which the front frame set 14 is rotated to the right by about 90 ° is the opening limit position to the right.

  As described above, each of the inner frame 12 and the front frame set 14 can be easily pressed into the outer frame 11 and the inner frame 12 to be restrained in a closed state. , The key K1 is rotated while pressing the key, the key K1 is rotated clockwise without pressing the cylinder lock 62, and the key K1 is rotated counterclockwise without pressing the cylinder lock 62. Accordingly, three types of opening, that is, opening the inner frame 12, opening the front frame set to the left, and opening the front frame set to the right can be easily performed.

  In the above configuration, an upper right shaft support 70A, a lower right shaft support 70B, an upper left shaft support 70C, and a lower left shaft support 70D are provided at the upper right, lower right, upper left, and lower left corners of the inner frame 12, respectively. The shaft support 70A and the lower right shaft support 70B are a pair on the right side, the upper left shaft support 70C and the lower left shaft support 70D are a pair on the left side, and these two sets are a pair, for example, an upper right shaft support 70A and a lower right shaft support 70B. , So that the opening operation is performed collectively (up and down) in any one of a pair of left and right pairs so that the opening operation is performed selectively.

  In addition, according to the above configuration, the front frame set 14 is in a state in which one of the pair of left and right pivots is opened in an unconstrained state, that is, in a state in which the pivots are left-opened or right-opened, By further opening the pair of shaft supports in the unconstrained state, the front frame set 14 can be easily removed from the inner frame 12.

  Here, as described above, the front frame set 14 can be opened leftward or rightward depending on whether the cylinder lock 62 is rotated clockwise or counterclockwise with the key K1 without being pressed. (In the present specification, such a system that can be selectively opened freely in any direction is also referred to as “two-way opening”). Has a structure suitable for such a two-way opening configuration, and electrically connects the front frame set 14 and the main body of the pachinko machine 10. Hereinafter, this connection structure will be described.

  As shown in FIGS. 21 to 24 and FIGS. 28 to 31, a wiring guide 90 is provided between the inner frame 12 and the front frame set 14. The wiring guide 90 is configured by connecting a first member 91 and a second member 92, as shown in FIGS.

  The first member 91 extends in a strip shape in the lateral direction, and has a main body 91B made of a plate-like piece that stands upright so that the width direction coincides with the vertical direction. A rib 91R made of a plate-like piece integrally joined at the center in the width direction to the upper end edge of the main body 91B in a posture lying down so that the directions coincide with the horizontal direction, and has a T-shaped cross section as a whole It is a member made of a resin extending in the lateral direction. The rib 91R is bent at a right angle toward the center in the width direction (height direction) of the main body 91B at a position slightly inside one end of the main body 91B, extends downward so as to sandwich the main body 91B from both sides, and extends in the width direction of the main body 91B. At the center (in the height direction), it is bent at right angles toward one end of the main body 91B and extends. That is, the main body 91B and the rib 91R extend in a cross-shaped cross section from the bent position to the tip of the main body 91B. A bearing 91C is integrally formed at the tip of the main body 91B and the rib 91R. The bearing portion 91C has a circumferential surface on the opposite side (right side in FIG. 50) of the cylindrical main body 91B extending vertically with the same length as the width (height) of the main body 91B so as to be stripped in the longitudinal direction. And has a shape extending vertically up and down in a C-shape in cross section, and furthermore, both end edges at the open portion at the tip end are each extended in a square piece while slightly expanding to the tip end side. . Further, in the main body 91B, the rib 91R extending along the upper end edge is located near the other end of the rib 91R from the position inside the portion bent at a right angle toward the center in the width direction (height direction) of the main body 91B as described above. Are formed at a plurality of locations (four locations) at regular intervals up to the position shown in FIG. Is established. A shaft 91S is integrally formed at the other end of the main body 91B (an end opposite to the end on the bearing 91C forming side). The shaft portion 91S is formed with one end portion of two plate-shaped bodies having an oblong shape arranged side by side in parallel with each other with the upper and lower edges at the other end portion of the main body 91B sandwiched from above and below. A rotating shaft (not shown) is formed integrally between the other ends of the plate-like body.

  The second member 92 is a member having the same size and shape as the first member 91 and made of the same resin, and has the same main body 92B, rib 92R, bearing 92C, and hooks as those of the first member 91. It has a configuration having a stop hole 92P and a shaft portion 92S. Therefore, further description of the second member 92 will be omitted.

  The rotating shaft of the shaft portion 92S of the second member 92 is press-fitted and supported by the bearing portion 91C of the first member 91, so that the first member 91 and the second member 92 move around the vertical axis. The wiring guide 90 is configured to be rotatably connected.

  As shown in FIGS. 22 and 28, the body-side bearing portion 12C is provided at the center of the upper end of the front surface of the inner frame 12, and the front door-side shaft member 14S is provided at the center of the upper end of the rear surface of the front frame set 14. It is arranged. As shown in FIGS. 50 and 51, the main body side bearing portion 12C has the same thickness (height) as the width (height) of the main body 91B of the first member 91, and has an arc-shaped tip in plan view. It is formed in a substantially U shape so as to protrude forward from the front surface of the inner frame 12. A rotating shaft (not shown) of the shaft portion 91S of the first member 91 is inserted into the distal end portion of the main body side bearing portion 12C, and is rotatably supported by the shaft. Above the main body side bearing portion 12C, an open / close detection switch 12S protruding in a horizontally long rectangular parallelepiped shape is protruded to a position near the tip of the main body side bearing portion 12C. The open / close detection switch 12S is configured to be immersed in the inner frame 12 when pressed rearward, and functions as a switch for detecting opening / closing of the front frame set 14. Since the open / close detection switch 12S for detecting the opening / closing of the front frame set 14 is provided at the center of the upper end of the front surface of the inner frame 12, the front frame set 14 can be opened right even when the front frame set 14 is opened left. In this case, on / off is performed at the same timing. The front door-side shaft member 14S has a pivot shaft (not shown) between an upper wall and a lower wall formed at the same interval as the width (height) of the main body 92B of the second member 92. ) Are provided, and the right and left sides have a cylindrical shape having a shaft in the front-rear direction, and a screw insertion portion having a screw insertion hole therein is integrally formed. As shown in FIGS. 22 and 28, the upper end portion of the front frame set 14 is elongated in a groove shape along the upper edge from a position immediately adjacent to the upper right pivot support portion 70A to a position immediately adjacent to the upper left pivot support portion 70C. The front door-side shaft member 14S is fitted into the center of the recess 14N, and is fixed with a screw through a screw insertion portion. The rotating shaft (not shown) of the front door side shaft member 14S is press-fitted into a bearing 92C of the second member 92, whereby the bearing 92C is rotatably mounted on the front door side shaft member 14S. It is being supported.

  The total length of the wiring guide 90 is determined by the main body side bearing portion 12C and the front door side shaft when the front frame set 14 is at an open limit position to the left or right, that is, at a position rotated about 90 ° to the left or right. The distance is set to be slightly larger than the distance to the member 14S. Accordingly, when the front frame set 14 is at the left or right opening limit position as shown in FIGS. 21 to 24 and FIGS. 28 to 31, the wiring guide 90 is moved to its central portion, that is, the first member. The connection between the bearing portion 91C of the first member 91 and the shaft portion 92S of the second member 92 is maintained in a posture slightly bent in a substantially rectangular shape in a plan view so as to protrude to one side (left side in the present embodiment). It has become. Thus, when the front frame set 14 is closed from the left or right opening limit position, the wiring guide 90 is caused to reliably and smoothly bend. That is, a problem that the wiring guide 90 is used as a stay to prevent rotation of the front frame set 14 is hardly generated. In this configuration, regardless of whether the front frame set 14 is opened rightward or leftward, the wiring guide 90 is always larger or smaller and bent toward one side (the left side in the present embodiment). It may be bent to either the right side or the left side.

  When the front frame set 14 is further closed, the wiring guide 90 is further bent accordingly, and when the front frame set 14 is closed to the end, the wiring guide 90 is in a folded position, It is stored between the inner frame 12 and the front frame set 14, specifically, in the recessed portion 14N of the front frame set 14.

  As shown in FIG. 52, the wiring guide 90 holds a harness 93 that electrically connects the front frame set 14 and the pachinko machine 10 main body. That is, the plurality of harnesses 93 are fixed to the wiring guide 90 while being bundled by the harness fastener 94. The harness fastener 94 has a rectangular bottom piece 94B having a long side slightly smaller than the width of the hook holes 91P and 92P in the first and second members 91 and 92 of the wiring guide 90 and a short side smaller than the long side. The two long sides of the bottom piece 94B extend upward to form two parallel extension pieces, one of which extends outward (to the right in FIG. 52) by being bent at a right angle. The lower extending piece 94E is formed, and the other extending piece extends further upward than the lower engaging piece 94E and is bent inward to be in the same direction as the lower engaging piece 94E. Are formed integrally with resin as a whole so as to extend substantially in parallel to the same position to form the upper engaging piece 94E. The interval between the upper and lower hook pieces 94E is slightly larger than the vertical width (height) of the hook holes 91P and 92P. Further, the upper and lower hooking pieces 94E are formed with slopes so that the thickness gradually increases upward and downward from the tip, respectively, and return to the original thickness of the hooking piece 94E at a certain distance from the tip. And a claw portion projecting vertically in a generally triangular cross section as a whole is formed. A plurality of harnesses 93 are inserted into the harness fastener 94 from between the upper and lower hook pieces 94E, and in this state, the upper and lower hook pieces 94E are pressed into the hook holes 91P and 92P of the wiring guide 90. You. The upper and lower hook pieces 94E enter the hook holes 91P and 92P while being elastically deformed so as to slightly approach each other, and when pressed to the end, the claw portions of the upper and lower hook pieces 94E respectively become hook holes. The harness fasteners 94 are fixed to the hook holes 91P, 92P by being hooked on the upper edge and the lower edge of the pins 91P, 92P.

  One side of the harness 93 is connected to a sub-control board disposed on the pachinko machine 10 through the center of the upper end of the inner frame 12, and the other side of the harness 93 is connected to the center of the upper end of the front frame set 14, It is connected to electric components such as light emitting means such as the various lamps. Here, in the present pachinko machine 10, since the front frame set 14 is attached to the inner frame 12 so as to be able to open in two ways as described above, the connection is temporarily made at one of the right and left ends. Then, when the front frame set 14 is opened with the connected one shaft supporting portion in the unconstrained state, the connection portion on the inner frame 12 side and the connection portion on the front frame set 14 side are separated as much as possible. As a result, the length of the wiring between them becomes the maximum, so that the storing of the wiring is cumbersome and requires a lot of space, and the wiring tends to be a hindrance when the front frame set 14 is open. Therefore, in the present pachinko machine 10, as described above, the inner frame 12 and the front frame set 14 are electrically connected to each other via the left and right center of the inner frame 12 and the left and right center of the front frame set 14. Therefore, the length of the wiring, that is, the harness 93, is minimized, so that the wiring is easy to store and hardly interferes.

  Further, in the pachinko machine 10, the harness 93 is configured to be guided while being held by the wiring guide 90 serving as a guide member. As described above, the length of the harness 93 provided between the inner frame 12 and the front frame set 14 is minimized, but the harness 93 can be used alone without using other members. When the front frame set 14 is closed, the posture of the harness 93 is not constant, and the harness 93 protrudes outside the pachinko machine 10 or is caught by any protruding structure in the vicinity, The harness 93 itself is likely to be damaged, and the appearance is likely to be impaired. In addition, even when the front frame set 14 is opened, if the harness 93 is laid alone as it is, the harness 93 is directly subjected to any external force applied thereto, and is liable to be damaged. On the other hand, by guiding the harness 93 while holding it with the wiring guide 90 as described above, it is possible to prevent the harness 93 from protruding outside or being caught in the closed state with the front frame set 14 closed. Can be stored in any position. Further, even when the front frame set 14 is open, the harness 93 is protected by the wiring guide 90, and the influence of the external force is reduced.

(Action)
The pachinko machine 10 includes a main body member (a game board 30 in which a game area in which a game ball flows down is formed on a front surface) and a front frame set as a front door that covers a front surface (a board surface of the game board 30) of the main body member. 14 and a key operation mechanism using a cylinder lock 62 for opening the front frame set 14, the front frame set 14 includes a pair of opposed right edge portions, At the left edge, the upper and lower right pivots 70A and 70B and the upper left and lower left pivots 70C and 70D are detachably pivoted to the inner frame 12, which is a member on the gaming machine main body side, by a pivoting mechanism including: By operating the key operating mechanism using the cylinder lock 62, the pair of shaft support mechanisms (ie, a pair of upper right and lower right shaft supports 70A and 70B and upper left and lower left shaft supports 70C and 70D) is formed. Kicking has a structure capable of opening and closing either one of the shaft supporting condition as an axis.

  According to the above configuration, the front frame set 14 is pivotally supported on the inner frame 12 by the pivoting mechanism at the pair of edge portions, that is, the left and right end edges, so that the front frame set 14 is closed (closed state). Can be restrained. On the other hand, in this closed state, the key operating mechanism using the cylinder lock 62 is operated (opening operation) to open and close with one of the pivotal support states of the pair of pivotal support mechanisms as an axis. Can be pivoted to open the door. That is, it is possible to freely select which of the pair of edges in the front frame set 14, that is, the left and right edges, which edge is the fixed end (supporting end) and which edge is the free edge. The front frame set 14 can be freely and selectively opened to any one of the pair of edges, that is, the front frame set 14 can be opened in two ways. It has become.

  Therefore, when performing various operations on the board surface, the front frame set 14 is opened to the edge portion side relatively away from the part to be operated so that the front frame set 14 does not disturb the operation. can do.

  In addition, by selectively opening the front frame set 14 to one side of the gaming machines on both sides which is relatively hard to obstruct, for example, because the game is not being played, the front frame set 14 is It is also possible not to disturb the game of the gaming machine adjacent to the side.

  In addition, the above-described pivoting mechanism includes a pair of operating pieces 72F and 73F disposed on the inner frame 12 which is a member of the main body of the gaming machine, and a rotating shaft 82S disposed on the front frame set 14 which is a front door. The pair of operating pieces 72F, 73F are normally opened and opened and biased by a compression coil spring 78, which is a biasing means, so that they are normally held in a closed posture. The operating pieces 72F and 73F are provided with shaft fitting notches 72R and 73R, respectively, and as the operating pieces 72F and 73F are closed, the shaft fitting notches 72R and 73R are integrated to form a shaft insertion hole. The front frame set 14 is easily and reliably detachably attached to the inner frame 12 by opening and closing the two operating pieces 72F and 73F and inserting the rotary shaft 82S into the shaft insertion holes. Can be supported It has become way.

  Further, when the key operation mechanism inserts the key K1 and rotates it to one side, one of the pivotal support states of the pair of pivotal support mechanisms can be released. Is rotated so that the other of the pivotal support states of the pair of pivotal support mechanisms can be released, so that the two-way opening of the front frame set 14 can be easily and reliably performed by operating the key K1. To be able to do it.

  In addition, the power generated by the rotation of the key K1 is transmitted through the first to fourth wires 76A, 76B, 76C, and 76D, which are linear members, so that the pair of shaft support mechanisms, that is, the upper right and lower right shafts are provided. Since a pair of the support portions 70A, 70B and the upper left and lower left shaft support portions 70C, 70D are driven, respectively, the upper right, lower right, upper left positions which are the driving positions separated from the insertion portion of the key K1, that is, the cylinder lock 62. The power is effectively transmitted to each of the lower left shaft supports 70A, 70B, 70C, and 70D by a simple configuration.

  A member on the gaming machine main body side on which the front frame set 14 as the front door is pivotally supported is an inner frame 12, and the inner frame 12 is another outer frame on the gaming machine main body side. When the key operating mechanism is rotated while inserting and pushing the key K1, the inner frame 12 is closed with respect to the outer frame 11 and the locked state is released. Therefore, three kinds of opening operations including the opening of the inner frame 12 and the opening of the front frame set 14 in two ways can be easily and reliably performed by operating the key K1.

  Also, the pachinko machine 10 has a front member that is a front door that covers a main body member (a game board 30 having a game area in which a game ball flows down is formed on the front face) and a front face of the main body member (the board face of the game board 30). In a configuration including a frame set 14 and an operation mechanism using a cylinder lock 62 for opening the front frame set 14, the front frame set 14 is a pair of right edge portions, which are a pair of opposite edge portions. And at the left edge thereof are detachably supported by the inner frame 12, which is a member of the main body of the gaming machine, by a shaft support mechanism including upper right and lower right shaft supports 70A and 70B and upper left and lower left shaft supports 70C and 70D. By operating the operating mechanism using the cylinder lock 62, the pair of shaft support mechanisms (that is, a pair of upper right and lower right shaft supports 70A and 70B and upper left and lower left shaft supports 70C and 70D). The front frame set 14 and the inner frame 12 are configured to be openable and closable about any one of the pivotal support states, and through a substantially central position between the pair of opposed edge portions. Are electrically connected to each other.

  According to the above configuration, the front frame set 14 is pivotally supported on the inner frame 12 by the pivoting mechanism at the pair of edge portions, that is, the left and right end edges, so that the front frame set 14 is closed (closed state). Can be restrained. On the other hand, in this closed state, the operating mechanism using the cylinder lock 62 is operated (opening operation) to open and close one of the pivotal support states of the pair of pivotal support mechanisms, thereby opening and closing the front frame set 14. It can be pivoted to open the door. That is, it is possible to freely select which of the pair of edges in the front frame set 14, that is, the left and right edges, which edge is the fixed end (supporting end) and which edge is the free edge. The front frame set 14 can be freely and selectively opened to any one of the pair of edges, that is, the front frame set 14 can be opened in two ways. It has become.

  Therefore, when performing various operations on the board surface, the front frame set 14 is opened to the edge portion side relatively away from the part to be operated so that the front frame set 14 does not disturb the operation. can do.

  In addition, by selectively opening the front frame set 14 to one side of the gaming machines on both sides which is relatively hard to obstruct, for example, because the game is not being played, the front frame set 14 is It is also possible not to disturb the game of the gaming machine adjacent to the side.

  By the way, since the front frame set 14 is provided with electric components such as light emitting means such as the various lamps, it is necessary to electrically connect the front frame set 14 and the pachinko machine 10 body. However, in a conventional gaming machine, the front door is always pivotally supported at one side edge, so that wiring is performed on this pivoted side to electrically connect the front door and the gaming machine body. I should have connected. However, in the pachinko machine 10, the front frame set 14 is configured to be openable in two ways as described above, and the front frame set 14 can be separated from the pachinko machine 10 body on any side. The connection is hard to make.

  Therefore, in the present pachinko machine 10, the front frame set 14 and the inner frame 12 on the main body side of the pachinko machine 10 are connected to each other through the central position between the pair of edges, that is, the right edge and the left edge. Are electrically connected. Thus, while the front frame set 14 is configured to be openable in two ways, the electrical connection between the front frame set 14 and the pachinko machine 10 main body is easily and reliably made.

  Further, the front frame set 14 and the inner frame 12 are electrically connected by a harness 93 serving as a wiring, and the harness 93 is guided while being held by a wiring guide 90 serving as a guide member. Therefore, in a state where the front frame set 14 is closed, the harness 93 is stored in an appropriate posture without protruding or being caught outside, and on the other hand, even when the front frame set 14 is opened, The harness 93 is protected by the wiring guide 90 so that the influence of the external force is reduced.

  Further, since the wiring guide 90 is configured to be foldable, the wiring guide 90 is compactly stored between the inner frame 12 and the front frame set 14 in a folded posture as the front frame set 14 is closed. Is to be able to be.

  In addition, since the front frame set 14 is formed with the recessed portion 14N that can store the folded wiring guide 90, the wiring guide 90 can be stored more compactly.

(Modification)
Various changes can be made to the above embodiment, for example, as described below.

(1) In the above embodiment, a pair of operating pieces 72F, 73F that are configured to be openable and closable are provided with shaft fitting notches 72R, 73R, respectively, and when the operating pieces 72F, 73F are closed, both shafts are fitted. A notch 72R, 73R is integrally formed to form a shaft insertion hole, and a shaft support mechanism is configured such that the rotary shaft 82S is inserted into the shaft insertion hole. However, for example, as shown in FIG. 53, a configuration in which a rotating shaft 96 is detachably supported on an engagement ring 95 configured to be openable and closable is also possible. Note that the pivot mechanism according to the modification shown in FIG. 53 is similarly configured at both left and right ends of the gaming machine. Therefore, in FIG. 53, only the right end of the gaming machine is shown, and the left end is Illustration is omitted.

  In the pivot mechanism according to the modification shown in FIG. 53, base portions 95B projecting forward in a generally trapezoidal shape in a plan view are provided on both left and right sides of the gaming machine main body side member 97, respectively, and a front door (not shown) is provided. Rotating shafts 96 extending vertically are disposed on both left and right sides of the shaft. A concave portion 95R is formed on the distal end surface of the base portion 95B so as to be recessed rearward in a semicircular shape in plan view. Inside the base 95B, a movable ring piece 95M having a substantially semicircular shape in plan view can be accommodated behind the recess 95R so as to be movable in the circumferential direction along the peripheral surface of the recess 95R. , From the one side (the left side in FIG. 53) of the recess 95R, and is normally pushed forward by a biasing means (not shown) as shown by an arrow A21 in FIG. In FIG. 53, it rotates about 180 degrees in the counterclockwise direction) and is held in a closed posture forming a shaft insertion hole having a substantially circular shape in plan view together with the recess 95R. In this manner, the movable ring piece 95M in the closed position is configured such that the power generated by operating the key with the cylinder lock is transmitted via a drive mechanism (not shown), and thereby the inside of the base 95B is indicated by an arrow A22 in FIG. 53 (clockwise direction in FIG. 53), whereby the front of the recess 95R is opened, and the rotation shaft 96 can be attached and detached.

  With the pivot mechanism according to this modification, the front door can be opened in two ways as in the case of the above embodiment. However, in the case of the above-described embodiment, the rotary shaft 82S can be inserted into the shaft insertion hole only by pushing it in. On the other hand, in the case of this modification, the movable ring piece 95M in the closed posture is opened. The rotation shaft 96 cannot be inserted into the shaft insertion hole until the rotation is completed. Further, in the case of this modification, the rotation range of the ring piece 95M is large, and the driving mechanism tends to be slightly complicated. From these points, the shaft support mechanism according to the above embodiment is more advantageous.

(2) Further, as shown in FIG. 54, for example, as shown in FIG. 54, a structure in which the rotation shaft 111 is supported so that the rotation shaft 111 can be detached forward only when the front door is in a closed position is also possible. It is. The pivot mechanism according to the modification shown in FIG. 54 is configured to be symmetrical at both left and right ends of the gaming machine. Therefore, FIG. 54 shows only the right end of the gaming machine, and the left end thereof. Are not shown.

  In the shaft support mechanism according to the modification shown in FIG. 54, shaft insertion portions 113 protruding forward are provided on both left and right sides of the gaming machine main body side member 112, respectively, and are provided on both left and right sides of a front door (not shown). , And a rotating shaft 111 extending vertically. A shaft insertion hole 113P that penetrates vertically in a circular shape in a plan view is formed at a tip end of the shaft insertion portion 113, and a diameter of the shaft insertion hole 113P is formed in a front peripheral portion of the shaft insertion hole 113P. A slit 113S having a smaller width W11 is formed. Thus, the distal end portion of the shaft insertion portion 113 has a substantially C-shape in plan view in which the shaft insertion hole 113P communicates with the space in front through the slit 113S. The rotary shaft 111 is a metal round bar-shaped shaft having a diameter slightly smaller than the diameter of the shaft insertion hole 113P. However, as shown in FIG. Further, indentations 111R each having a thickness (height) H11 slightly larger than the thickness of the shaft insertion portion 113 and indenting in a rectangular shape in a side view from both right and left sides to the center side are respectively formed. The distance D11 between the two indentations 111R is slightly smaller than the width W11 of the slit 113S in the shaft insertion portion 113. The peripheral surface of the rotating shaft 111 is cut into a substantially D-shaped cross section by forming the two indented portions 111R. However, the movable body 111M having the same peripheral surface as the cut peripheral surface is formed on both sides. The indentations 111R are fitted into the respective indentations 111R, and are held movably along the indentation direction of the indentations 111R. Each movable body 111M is urged outwardly by an urging means inside the indentation 111R (not shown), and its peripheral surface is usually the periphery of the rotation shaft 111 as shown in FIG. It is held at a position flush with the surface. In other words, the movable body 111M normally supplements the cutout of the rotating shaft 111, so that the rotating shaft 111 has the same outer shape as a complete round bar. As shown by an arrow A24 in FIG. 55, when the movable body 111M is pushed inward (toward the center of the rotation shaft 111) against the urging force of the urging means, each movable body 111M comes into both the indentations 111R. I have.

  As shown in FIG. 54 (a), when the front door (not shown) is closed, the rotating shaft 111 is fitted into the shaft insertion hole 113P of the shaft insertion portion 113 and is supported by the shaft. At this time, each movable body 111M is protruded to the left and right sides to the limit position by being urged outward as described above, and its peripheral surface is held in a posture coplanar with the peripheral surface of the rotating shaft 111. Therefore, since the peripheral surfaces of both movable bodies 111M are held in the shaft insertion hole 113P by the urging force of the urging means so as to be in a posture widened to the left and right more than the width W11 of the slit 113S, the normal state is usually used. It is held in a posture supported by the shaft insertion hole 113P without detaching outward (forward) from the slit 113S. At this time, the front door is locked by a cylinder lock and an engagement mechanism (not shown) at one central portion in the left-right direction, and is thereby restrained in a closed state.

  As shown in FIG. 54 (b), the locked state by the cylinder lock is released, and as shown by an arrow A25 in FIG. 54, one side (the right side in FIG. 54) of the front door is pulled forward to rotate the rotation shaft 111. When the movable body 111M is moved outward (forward) from the inside of the insertion hole 113P, the peripheral surfaces of both movable bodies 111M abut on both ends of the slit 113S on the way, but the rotating shaft 111 further faces outward (front). As the movable body 111M moves, the peripheral surface of the movable body 111M becomes a cam surface, and the movable body 111M is pushed into the indented portion 111R against the urging force of the urging means, thereby being retracted. Then, the rotating shaft 111 escapes outward (forward) from the inside of the shaft insertion hole 113P, the support state is released, and the front door is supported by the other side (left side) support mechanism and opened to the left like an open door. It can be left open, that is, open left. On the other hand, from the left-opened state, one side (the right side in FIG. 54) of the front door is again moved toward the original position, that is, backward, and at this time, the rotating shaft 111 is inserted into the slit 113S of the shaft insertion portion 113. When it is pushed in, the peripheral surface of the movable body 111M becomes a cam surface and is pushed into the indentation 111R and immersed in the same manner as in the above-mentioned case of pulling out (opening operation). It is re-inserted into the pin 113P and returns to the same axial support posture as that shown in FIG.

  On the other hand, from the state where the front door is closed and locked by the cylinder lock as shown in FIG. 54 (a), this locked state is released, and the pivotal support state on the other side (left side) of the front door is changed to the above-mentioned one side ( When the front door is opened rightward as in the case of the right side), the pivot mechanism on one side (right side) of the front door functions as a hinge, as shown in FIG. 54 (c). The rotation shaft 111 rotates in the shaft insertion hole 113P of the shaft insertion portion 113. When the rotation shaft 111 rotates, the indentation direction of the indentation portion 111R (or the moving-in / out direction of the movable body 111M) assumes a posture slightly inclined back and forth from the left and right directions, as shown in FIG. Parts other than the movable body 111M are stuck on both sides of the slit 113S and cannot escape from the shaft insertion hole 113P. That is, while the rotating shaft 111 rotates, the rotating shaft 111 cannot escape from the inside of the shaft insertion hole 113P, and is therefore securely held in the posture supported by the shaft insertion hole 113P.

  As described above, when the locked state is released from the state where the front door is closed and the cylinder is locked by the cylinder lock, any of the pivoted state in the left-sided pivot support mechanism and the pivoted state in the right-sided pivot support mechanism is performed. Either one can be freely released selectively, and when the supporting state of one of the supporting mechanisms is released, the other supporting mechanism can reliably hold the supporting state and function as a hinge. It has become. Thereby, the front door can be easily and reliably opened in two ways.

(3) In the above-described embodiment, the power generated by the rotation of the key K1 is transmitted through the first to fourth wires 76A, 76B, 76C, and 76D, which are linear members. A pair of the upper right and lower right pivots 70A, 70B and the upper left and lower left pivots 70C, 70D were respectively driven. In addition to the mechanism in which the power is transmitted mechanically exclusively, For example, a mechanism may be used in which the electric switch is turned on by the rotation of the key, and the power of a drive source such as a motor or a solenoid is transmitted to drive the shaft support (not shown). According to the mechanism in which power is transmitted using electric control in this manner, it is necessary to provide a transmission means such as a linear member that mechanically transmits power to a shaft support portion separated from the key operation position. Therefore, the configuration can be simplified.

(4) In the above-described embodiment, the key operating mechanism using the cylinder lock 62 by operating the key K1 is configured as the operating mechanism for opening the front door. In addition to the key operating mechanism, for example, a mechanism may be provided that includes operating means such as knobs and levers that operate without using a key, and that the power of the operating means is transmitted to open the shaft support (not shown). . However, in this case, it is usually necessary to separately provide a mechanism for locking the front door with a key. Therefore, as in the above embodiment, the function of opening the front frame set 14 and the function of locking with the key K1 are combined. The key operation mechanism provided can simplify the configuration.
Further, as the operation mechanism, in addition to the one operated by inserting the key K1 as in the above-described embodiment, for example, a mechanism remotely operated by a remote controller or the like may be used.

(5) In the above embodiment, the key operating mechanism rotates the key with the key K1 while pressing the cylinder lock 62, rotates the key K1 clockwise without pressing the cylinder lock 62, and does not depress the cylinder lock 62. With the three operations of rotating the key K1 in the counterclockwise direction, the opening of the inner frame 12, the opening of the front frame set to the left, and the opening of the front frame set to the right can be opened in three ways. For example, a key operation mechanism for opening the front door left and right and a key operation mechanism for opening the inner frame may be separately provided (not shown). However, from the point of view of the simplicity of the mechanism, the arrangement space, and the like, it is desirable to adopt a configuration in which three types of opening can be performed by one common key operation mechanism as in the above embodiment.

(6) In the above-described embodiment, the first to fourth wires 76A, 76B, 76C, and 76D are used as the linear members for transmitting the motive power for driving the shaft support mechanism. Any material can be used as long as it has a high degree of flexibility and tensile strength. For example, members of various forms such as thread, string, belt, and chain made of various materials such as resin, rubber, and metal can be used. Can be used.

(7) In the above embodiment, the front frame set 14 and the inner frame 12 are electrically connected by the harness 93 serving as a wiring, and the harness 93 is guided while being held by the wiring guide 90 serving as a guide member. However, for example, as shown in FIG. 56, connection terminal portions are disposed at the left and right central portions of the front door and the corresponding left and right central portions of the gaming machine body side member, and the front door is When closed, these connection terminals may be connected to each other.

  In the connection structure according to the modification shown in FIG. 56, a horizontally long rectangular parallelepiped concave portion 98R is formed at the center of the upper end on the rear surface of the front frame set 98 that is the front door, and a connection terminal portion is formed at the center in the concave portion 98R. A plug connector C11 is arranged and fixed. On the other hand, a receptacle connector C12 is arranged and fixed as a connection terminal at the center of the upper end on the front surface of the inner frame 99 which is a member on the main body of the gaming machine. When the front frame set 98 is closed, the plug connector C11 is inserted into the receptacle connector C12 as shown by an arrow A23 in the same figure, whereby the front frame set 98 and the inner frame 99 are electrically connected. It has become.

  According to the connection structure according to the present modification, it is not necessary to lay a wiring (harness) between the front frame set 98 and the inner frame 99. Therefore, when the front frame set 98 is opened, the front frame It is possible to avoid a situation in which wiring is erected in the air between the set 98 and the inner frame 99 to be in a position easily affected by an impact, and to provide a member for guiding the wiring while protecting the wiring from such an impact. Can also be eliminated. Further, even when the front frame set 98 is closed, it is not necessary to provide a means or a space for accommodating the wiring and the guide member.

(8) In the above embodiment, the wiring guide 90 serving as the guide member is configured to fix the plurality of harnesses 93 while bundling them with the harness fastener 94, but the guide member may be, for example, a cylindrical member. It is also possible to adopt a configuration in which a plurality of harnesses are guided inside and held while being guided. However, according to this configuration, it takes time to insert a plurality of harnesses into the interior, and it is possible to open and close the harnesses to facilitate the insertion of the harnesses. Becomes complicated. Therefore, from such a point, a configuration like the wiring guide 90 according to the above embodiment is advantageous.
The means for fixing the harness 93 is not limited to the above-mentioned harness fastener 94, and any other means can be used. For example, the band has an insertion hole at one end, the band is wound around the object (harness) in an annular shape, and the other end is inserted into the insertion hole and narrowed so that the annular portion is reduced. May be fixed to the hooking holes 91P and 92P of the wiring guide 90 using a binding band configured to bind the harness 93 (not shown).

(9) In the above-described embodiment, the front frame set 14 and the inner frame 12 are electrically connected to each other via a position exactly at the center between the right edge and the left edge, which are a pair of opposite edges. The front door and the member on the gaming machine main body side are electrically connected to each other through a substantially central position between a pair of opposed edge portions. What should I do?

  In this case, the position of the electrical connection is, for example, within a range of about 30 to 70%, preferably about 40 to 60% when the entire interval between the pair of opposed edges is 100%. desirable. As the position of the electrical connection deviates from one of the central positions, the maximum distance between the connection portions also increases. However, if the position of the electrical connection is within the range of about 30 to 70%, such a case is obtained. The maximum distance between the connecting parts can be kept to an extent that does not become too large, so that when connecting the connecting parts with wiring (harness), the length can be made not to be too large. Further, even in the case where the connection terminal portions are connected to each other as in the above-described modification, the connection terminal portions abut against each other in the case where the connection terminals are left-opened and the case where the connection terminals are opened right, as the connection position is shifted from the center position. The difference in posture (angle) becomes large, and connection is likely to be unreasonable. For this reason, the position of the electrical connection varies depending on the structure of the connection terminal portion, the size (width) of the front door, and the like. In general, for example, when the entire interval between a pair of facing edges is 100%. It is desirable that the distance between the center and each side be about 10%, preferably about 5%. If the position of the electrical connection is within the above range, the difference in posture (angle) as described above can be suppressed to an extent that does not become excessive, and therefore, the configuration is such that the connection terminal portions can be connected without difficulty. be able to.

(10) In the above embodiment, one of the pivoting states in a pair of pivoting mechanisms (that is, a pair of upper right and lower right pivots 70A and 70B and upper left and lower left pivots 70C and 70D) is selected. For example, as schematically shown in FIG. 57, it is possible to open and close one of the pair of pivoting mechanisms around one of the pivoting mechanisms without releasing any of the pivoting states. It may be configured.

  In the modification shown in FIG. 57, a support frame 116, which is a member for supporting the front frame set 114, is disposed between a front frame set 114, which is a front door, and an inner frame 115, which is a member on the gaming machine main body side. ing. One end (left end in FIG. 57) of the front frame set 114 is pivotally supported on one end (left end) of the support frame 116 by a normal hinge mechanism 114H using a bracket. The other end (right end in FIG. 57) of the support frame 116 is hooked to the other end (right end) of the support frame 116 by a hooking mechanism (not shown) that can be attached and detached by an operating mechanism. It has become. The end (right end in FIG. 57) of the support frame 116 on which the front frame set 114 is hooked by the hook mechanism (not shown) is the end of the inner frame 115 corresponding to the end. A portion (right end) is supported by a normal hinge mechanism 116H using a bracket, and the other side end (left end in FIG. 57) of the support frame 116 is the other side end of the inner frame 115. (Left end) is locked by a locking mechanism (not shown) that can be attached and detached by an operation mechanism.

  When the end of the front frame set 114 and the support frame 116 on the side where the locking mechanism is provided is pushed in, the support frame 116 and the inner frame 115 are respectively closed and closed as shown in FIG. Held in state. As shown in FIG. 57 (b), when the operating mechanism is operated to release the locked state between the front frame set 114 and the support frame 116, the front frame set 114 is pivotally supported at the end (in FIG. 57, the left end). ) To open one side (to the left) as an opening door as shown by an arrow A26, that is, a state where left opening is possible. On the other hand, as shown in FIG. 57 (c), when the operating mechanism is operated to release the hooked state between the support frame 116 and the inner frame 115, the support frame 116 is moved to the pivot-side end (the right end in FIG. 57). ) To open the door to one side (right side) as shown by an arrow A27, that is, to open the support frame 116 to one side (right side) together with the front frame set 114, in other words, Then, the front frame set 114 can be opened rightward.
