(First embodiment)
A first embodiment of a pachinko gaming machine (hereinafter simply referred to as "pachinko machine") will be described in detail below with reference to the drawings. As shown in FIG. 3, etc., the pachinko machine 10 has an outer frame 11 as a fixed frame forming the outer shell of the pachinko machine 10, and an inner frame 12 as a game board mounting frame is supported on one side of the outer frame 11 so as to be openable and closable. For the sake of convenience, FIG. 3 omits the game members (nails, accessories, etc.) provided on the game board 30, the glass unit 137 attached to the front frame set 14 as the front frame, and the like.

As shown in FIG. 6 and the like, the outer frame 11 includes an upper frame-constituting portion 11a and a lower frame-constituting portion 11b made of wooden plate material, and a left frame-constituting portion 11c and a right side frame-constituting portion 11d made of aluminum alloy extruded material.

An upper hinge 81 and a lower hinge 82 are attached to the upper and lower ends of the left side frame-constituting portion 11c (see FIG. 1). The upper and lower parts of the inner frame 12 are rotatably supported by the upper hinge 81 and the lower hinge 82, so that the inner frame 12 can be opened and closed. A space formed inside the outer frame 11 accommodates the inner frame 12 and the like.

An extension wall portion 83 that protrudes toward the inside of the outer frame 11 from the vicinity of the rear end in the width direction is formed on the right-side frame-constituting portion 11d. The extending wall portion 83 covers the entire upper and lower sections corresponding to the locking device 600 (see FIG. 6) provided on the back side of the right side portion of the inner frame 12 from the back side of the inner frame 12 (see FIG. 5). In addition, as shown in FIG. 3 , a pair of upper and lower receiving portions 84 and 85 to which the locking member of the locking device 600 is locked is provided on the front side of the extending wall portion 83 . A pressing portion 86 that abuts on an inner frame open detection switch 92 (to be described later) protrudes toward the inside of the outer frame 11 from the lower receiving portion 85 .

Further, a resin-made curtain plate decoration 87 is attached to the lower side frame-constituting portion 11b. A rib 88 protruding upward is integrally formed in the inner part of the upper surface of the curtain plate decoration 87 . This makes it difficult for a gap to be formed with the inner frame 12 .

As shown in FIG. 3, the opening/closing axis of the inner frame 12 is set vertically along the left side of the pachinko machine 10 when viewed from the front, and the inner frame 12 can be opened forward with this opening/closing axis as the axis. The inner frame 12 is mainly composed of a resin base 38 having a rectangular outer shape, and a substantially elliptical window hole 39 is formed in the central portion of the resin base 38 .

A front frame set 14 is attached to the front side of the inner frame 12 so that it can be opened and closed. As with the inner frame 12, the front frame set 14 can be opened forward with an opening/closing axis set along the top and bottom on the left side of the pachinko machine 10 as viewed from the front. Note that the front frame set 14 may be configured to be directly supported by the outer frame 11 instead of via the inner frame 12 so as to be openable.

The front frame set 14 has a rectangular outer shape like the inner frame 12, and covers substantially the entire front side of the inner frame 12 in the closed state. A substantially elliptical window portion 101 is formed in the central portion of the front frame set 14 . Thereby, the game board 30 (game area) attached to the rear surface of the inner frame 12 can be visually recognized from the outside through the window portion 101 of the front frame set 14 and the window hole 39 of the inner frame 12 . A detailed configuration of the game board 30 will be described later.

As shown in FIGS. 1 and 2, on the front side of the front frame set 14, a lower tray 15 as a ball receiving tray is provided at the center of the lower part, and the game balls discharged from the outlet 16 can be stored in the lower tray 15.例文帳に追加Further, on the front side of the lower tray 15, a ball extracting lever 25 for ejecting game balls from the inside of the lower tray 15 is provided.

A game ball shooting handle (hereinafter referred to as "handle 18") is provided on the right side of the lower plate 15 and protrudes forward. The handle 18 is provided with a touch sensor (not shown) and an operation amount detection means (variable resistor) (not shown) for detecting an operation amount of an operation portion of the handle 18 . Then, when the handle 18 is rotated clockwise, a game ball is shot by a shooting device 60 as a shooting means, which will be described later, with a force corresponding to the amount of rotation operation. Also, the handle 18 is provided with a firing prohibition button 18a that can be pressed with the thumb of the right hand holding the handle 18. As shown in FIG. When the shooting prohibition button 18a is pressed, shooting of game balls by the shooting device 60 is prohibited even if the handle 18 is gripped. Therefore, it is possible to rotate the handle 18 while prohibiting the shooting of the game ball, or temporarily stop shooting the game ball while gripping the handle 18.例文帳に追加

An upper plate 19 is provided above the lower plate 15 . The upper tray 19 is a ball receiving tray that temporarily stores game balls and guides them toward a launching device 60, which will be described later, while aligning them in a row. When the upper tray 19 is filled with game balls, the game balls to be paid out are guided to the lower tray 15 via the lower tray communication passage 71 and the discharge port 16, which will be described later.

A ball lending button 121 and a returning button 122 are provided on the upper surface of the upper plate 19. - 特許庁Thus, in a game hall or the like, when a ball lending button 121 is operated with bills, cards, etc. thrown into a card unit (ball lending unit) arranged on the side of the pachinko machine 10, the lending balls are supplied to the upper tray 19 according to the operation. On the other hand, the return button 122 is operated when requesting the return of the card or the like inserted in the card unit. However, the ball lending button 121 and return button 122 are unnecessary in a pachinko machine in which game balls are directly lent to the upper tray 19 from a ball lending device or the like without going through the card unit, that is, a so-called cash machine.

Also, the upper plate 19 is provided with a ball removal button 123 . By pressing the ball ejecting button 123, a communication passage (not shown) leading from the upper tray 19 to the lower tray 15 is opened, and the game balls stored in the upper tray 19 are guided (dropped) to the lower tray 15.例文帳に追加That is, the player can move the game ball on the upper tray 19 to the lower tray 15 at any time by operating the ball removal button 123 .

Furthermore, the upper surface of the upper plate 19 is provided with a performance button 125 and a cross button 126 (cursor keys) as operation means. A performance button 125 has a built-in LED, and by pressing the performance button 125, a corresponding performance is performed in a decorative pattern display device 42 or the like, which will be described later, or the performance content is changed.

Further, the front face of the front frame set 14 is provided with light emitting means such as various lamps around it. These light emitting means play a role of increasing the performance effect during the game by changing and controlling the light emitting mode in accordance with the change of the game state or the like. For example, on the periphery of the window portion 101, an annular illumination portion 102 containing light emitting means such as an LED is provided. In addition, error display lamps 104 are provided on both sides of the ring-shaped decorative portion 102 to light up in the event of a predetermined error. A large number of fine through-holes are formed in the annular illumination portion 102 above the error display lamps 104 so as to correspond to the speakers SP (see FIG. 3) provided on the rear surface of the front frame set 14 .

A glass unit 137 is attached to the back side of the front frame set 14 . The glass unit 137 does not have a conventional front and rear pair of rectangular plate glasses that are attached separately as a front and rear pair, but has a round shape as a whole and is attached after being assembled.

Next, the inner frame 12 will be described with reference to FIG. As described above, the game board 30 is attached to the inner frame 12 in contact with the back side of the resin base 38 on the rear side of the window hole 39 . Therefore, a substantially central portion of the front surface of the game board 30 is exposed to the front side of the inner frame 12 through the window hole 39 .

In addition, a shooting device 60 and a shooting rail 61 for guiding game balls immediately after being shot by the shooting device 60 are attached to the front lower portion of the inner frame 12 (resin base 38), that is, the position below the window hole 39. In this embodiment, a solenoid type launcher is adopted as the launcher 60 . Further, above the shooting device 60, a ball feeding device 63 is provided for guiding the game balls guided from the upper tray 19 one by one to the shooting position of the shooting device 60 by driving a built-in drive means (for example, a solenoid).

Next, the configuration of the game board 30 (game area) will be described with reference to FIG. The game board 30 is provided with a general winning port 31, a variable winning device 32, a first starting winning device 33a, a second starting winning device 33b, a through gate 34, a variable display device unit 35, and the like. As is well known, when a game ball enters (wins a prize) in various winning openings such as the general winning opening 31, the variable winning device 32, and the starting winning devices 33a and 33b, it is detected by various detection switches, and a predetermined number of winning balls are paid out to the upper tray 19 or the lower tray 15.

In this embodiment, 3 game balls are paid out when there is entry into the starting prize winning devices 33a and 33b, 10 game balls are paid out when there is entry into the general prize winning port 31, and 14 game balls are paid out when there is entry into the variable prize winning device 32. Also, even if a game ball passes through a through gate 34 which only passes the game ball but does not enter (is not discharged to the back side of the game board 30), the game ball is not paid out. In addition, the first starting winning device 33a, the general winning opening 31, and the through gate 34 are configured so that game balls moving in the game area can always enter or pass through, while the second starting winning device 33b and the variable winning device 32 are configured to change between an open state in which a game ball can enter and a closed state in which a game ball cannot enter.

In addition, the game board 30 is provided with an out port 36 corresponding to the lowest part of the game area, and game balls that do not enter various prize winning ports such as a general winning port 31 are discharged out of the game area through the out port 36.例文帳に追加The game board 30 is also provided with a large number of nails (game nails) for appropriately distributing and adjusting the falling direction of the game balls, and various members (accessories) such as windmills.

A variable display device unit 35 is arranged in substantially the center of the game area. A center frame 47 is arranged in the variable display device unit 35 so as to surround a decorative design display device 42 which will be described later. A ball entrance 151 into which a game ball can enter is provided on the left side and the right side of the center frame 47, and the game ball entering the center frame 47 through the ball entrance 151 is guided onto a stage 153 formed below the decorative pattern display device 42 via a warp flow path 152 extending vertically along the left and right sides of the decorative pattern display device 42. A game ball guided onto the stage 153 falls from the stage 153 to a front game area, or enters a pocket 154 formed on the central back side of the stage 153 after rolling on the stage 153. - 特許庁In addition, the pocket 154 communicates with a guide passage 155 that leads to a game area directly above the first starting prize winning device 33a, and a game ball entering the pocket 154 has a relatively high probability of entering the first starting prize winning device 33a described later.

Below the variable display device unit 35, a first starting winning device 33a is arranged. The first starting winning device 33a protrudes forward from the front portion of the game board 30, and a winning opening (starting winning opening) in which game balls can always win is opened on the upper side thereof. The first start-up winning device 33a of the present embodiment is not provided with an opening/closing member that changes the ease with which a game ball enters the first start-up winning device 33a.

A second start-up winning device 33b is arranged below the first start-up winning device 33a. The second starting winning device 33b is adjacent to both left and right sides of a winning opening (starting winning opening) of the second starting winning device 33b into which game balls can enter, and is provided with a pair of blade members 37 capable of rotating and displacing between an open position and a closed position. In particular, in this embodiment, when the blade member 37 is in the closed position, there is no room for the game ball to pass between the blade member 37 and the first start winning device 33a, and the second start winning device 33b is in a closed state in which it is impossible to let the game ball enter. On the other hand, when the blade member 37 changes to the open position where the blade member 37 opens outward, the second start winning device 33b is in an open state in which a gap for the game ball to pass is secured between the blade member 37 and the first start winning device 33a, and the game ball is allowed to enter, and the game ball moving on the side of the second start winning device 33b is guided to the start winning opening of the second start winning device 33b by the blade member 37.

Although details will be described later, the first start prize-winning device 33a and the second start prize-winning device 33b are provided with a first start prize-winning switch 224a and a second start prize-winning switch 224b as condition establishment detection means for detecting a winning game ball, respectively. 3a, 43b, and the decorative pattern display device 42 are configured to perform variable display. Then, when winning the lottery, a jackpot state is provided as a special game state in which the variable prize winning device 32 is opened.

Through gates 34 are arranged in the area located on the left side of the variable display device unit 35 (left side area) and the area located on the right side of the variable display unit 35 (right side area) in the game area. The through gate 34 is configured so that game balls flowing down the game area can pass one by one. The through gate 34 has a through gate switch 225 capable of detecting a game ball passing through the through gate 34, which will be described later in detail.

Although details will be described later, when a game ball is detected by the through gate switch 225, a ball entry support lottery is performed to determine whether or not the second start prize winning device 33b is to be opened, and a variable display for teaching the result of the ball entry support lottery is performed on the normal symbol display device 41. Then, when winning the ball-entering support lottery, the second starting prize-winning device 33b is opened for a specified time after the end of the variable display.

In the present embodiment, there are a "low probability state" in which a jackpot is won with a predetermined probability in a lottery, and a "high probability state" in which a jackpot is won with a higher probability than the low probability state in the lottery. Furthermore, there is a "high ball entry state" in which the opening/closing member 37 of the second start-up winning device 33b is opened relatively frequently to allow game balls to easily enter the second start-up winning device 33c, and a "low ball entry state" in which the opening/closing member 37 is hardly opened and game balls are difficult to enter the second start-up winning device 33b. Hereinafter, the low probability state and low ball entry state will be referred to as "normal mode", the low probability state and high ball entry state will be referred to as "time reduction mode", and the high probability state and high ball entry state will be referred to as "constant variable mode".

The high ball winning state includes, for example, (1) a state in which the fluctuation display time on the normal symbol display device 41 is shorter than that in the low ball winning state, (2) a state in which the opening time (specified time) of the second start winning device 33b is longer than in the low ball winning state, (3) a state in which the specified number of game balls that can be entered per opening of the second start winning device 33b is greater than in the low ball winning state, (4) a second start winning per ball winning support lottery. A state in which the number of times the device 33b is opened is higher than in the low ball entry state, and (5) a state in which the winning probability of the ball entry support lottery is higher than in the low ball entry state. The high ball entry state in this embodiment employs the configurations (1), (2), and (5) above. Of course, not limited to this, any one of the configurations (1) to (5) or any combination of the configurations (1) to (5) may be adopted as the “high ball entry state”. As a result, game balls are more likely to frequently win prizes in the second starting prize winning device 33b, the number of times winning/losing lotteries are executed increases, and a state in which the number of balls possessed by the player is suppressed from being reduced is maintained.

Furthermore, in the present embodiment, the normal mode and the probability variable mode are continued until the big win state occurs, whereas the time reduction mode is terminated when the variable display is performed 100 times on the special display devices 43a and 43b and the decorative pattern display device 42 even if the big win state does not occur, and the mode is shifted to the normal mode.

In addition, there are three types of jackpot types in this embodiment: a 15-round probability variable jackpot (hereinafter referred to as “15RS”) and a 16-round normal jackpot (hereinafter “15RN”). The opening of the variable prize winning device 32 for 30 seconds or the entry of eight game balls into the variable prize winning device 32 after the opening of the variable prize winning device 32 is regarded as one round, and after this is repeated 15 times, the jackpot state is completed. Further, after the jackpot state of "15RS" ends, the "probability variable mode" is given, and after the jackpot state of "15RN" ends, the "time reduction mode" is given.

A variable winning device 32 is provided below the second startup winning device 33b. The variable winning device 32 is provided with a large winning opening leading to the rear of the game board 30, a shutter for opening and closing the large winning opening, a large winning opening solenoid for operating the shutter, and a count switch 223 for detecting a game ball entering the large winning opening, and the variable winning device 32 (large winning opening) is switched between a closed state and an open state by controlling the driving of the large winning opening solenoid and opening/closing the shutter.

The variable winning device 32 is normally in a closed state in which game balls cannot enter, and is in an open state in which game balls can win in the case of a big win. In the variable winning device 32 of the present embodiment, the lower edge of the big winning shutter is rotatably supported along the lower edge of the big winning opening, and when the variable winning device 32 is closed, the big winning shutter extends vertically to close the big winning opening, and a game ball can pass in front of the big winning shutter. On the other hand, in the open state of the variable winning device 32, the big winning shutter rotates forward and extends back and forth (the upper surface is slightly downwardly inclined toward the rear), and the game balls flowing down in front of the big winning opening are received by the rear surface (upper surface) of the big winning shutter and guided to the big winning opening.

In addition, adjacent to the upper right part of the substantially elliptical game area, a first special display device 43a for performing variable display for teaching the result of the winning lottery performed based on the entry of the game ball into the first starting prize winning device 33a, a second special display device 43b performing variable display for teaching the result of the winning lottery performed based on the entry of the game ball into the second starting prize winning device 33b, and during the variable display on the special display devices 43a and 43b. When a game ball enters the starting prize winning devices 33a and 33b, a first holding display device 46a and a second holding display device 46b indicating that the variable display corresponding to the entering ball has been held and stored; A normal holding display device 44 is provided so as to be visually recognizable from the front of the pachinko machine 10, indicating that the variable display corresponding to the passage is held and stored when there is a pass. In this embodiment, the first special display device 43a, the second special display device 43b, the first reservation display device 46a, the second reservation display device 46b, the normal symbol display device 41, and the normal reservation display device 44 are directly display-controlled by the main control device 261 as main control means described later.

The first special display device 43a is composed of four LEDs (first special lamps). Triggered by the entry of the game ball into the first starting prize winning device 33a, the switching display (variable display) of the first special figure lamp is performed on the first special display device 43a.

The second special display device 43b is composed of four LEDs (second special lamps). Then, the switching display (variation display) of the second special figure lamp is performed on the second special display device 43b triggered by the entry of the game ball into the second starting prize winning device 33b.

After the variable display is performed for a predetermined time on the first special display device 43a and the second special display device 43b, the variable display is stopped based on the result of the lottery. That is, the lighting mode (combination of lighting special lamps) when the variable display is stopped is associated with various results of the lottery, and the result of the lottery, that is, 'big hit' or 'loss' is definitely displayed according to the lighting mode when the variable display is stopped.

Furthermore, in the first special display device 43a and the second special display device 43b, the jackpot type, ie, "15RS" or "15RN", is taught depending on the lighting mode (stop mode) to be stopped. In addition, there are not one but a plurality of stop modes of the first special display device 43a and the second special display device 43b that respectively teach various types of jackpots and failures, and one of them is selected and stopped.

Further, the stop display on the first special display device 43a and the second special display device 43b is configured to be maintained for a specified time, and the next variable display can be started after the specified time has passed. Furthermore, if the next variable display is not performed even after the specified time has passed after the stop display on the first special display device 43a or the second special display device 43b, the first special display device 43a or the second special display device 43b is configured to switch from the lighting mode indicating the result of the lottery to the lighting mode indicating the standby state in which the variable display is not performed. It should be noted that the configuration may be such that the lighting mode indicating the result of the lottery is maintained as it is.

Each of the first reservation display device 46a and the second reservation display device 46b is composed of two pieces (a first reservation lamp and a second reservation lamp). In the present embodiment, up to four variable displays (hereinafter referred to as "first variable displays") based on the entry of game balls into the first starting prize winning device 33a can be stored. Furthermore, it is configured to be able to hold and store up to four variable displays (hereinafter referred to as "second variable display") based on the entry of game balls into the second starting prize winning device 33b.

Further, for example, when the first variation display is suspended for one time, the first suspension lamp on the left side (on the inner circumference side of the game area) lights up, when the first variation display is suspended for two times, the left and right first suspension lamps light up, when the first variation display is suspended for three times, the left first suspension lamp blinks and the right first suspension lamp lights up, and when the first variation display is suspended for four times, the left and right first suspension lamps blink. In addition, when the game ball newly wins the starting winning devices 33a and 33b during the jackpot state, the variable display for that amount is also suspended.

Further, in this embodiment, the suspended variable display is completed in the order in which it was suspended regardless of whether it is the first variable display or the second variable display. In other words, for example, the second variable display held after the already held first variable display is digested earlier than the first variable display, so that the order of suspension is changed so that one of them is not preferentially digested.

The normal symbol display device 41 is composed of two LEDs (normal symbol lamps). Then, in the normal symbol display device 41, when the game ball passes through the through gate 34, for example, the normal symbol lamp on the right side (on the outer peripheral side of the game area) blinks (is variably displayed). Further, after the variable display is performed for a predetermined time on the normal symbol display device 41, the variable display is stopped based on the result of the entrance support lottery. In other words, the lighting mode (combination of lighting normal lamps) when the variable display is stopped is associated with various results of the ball entry support lottery, and the result of the ball entry support lottery is definitely displayed according to the lighting mode when the variable display is stopped. For example, by lighting both the left and right general pattern lamps, it indicates "winning", and by lighting only the left general pattern lamp, it indicates "off".

The normal hold display device 44 is composed of two LEDs (normal hold lamps). In this embodiment, up to four variable displays of the normal symbol display device 41 performed based on the passage of the game ball to the through gate 34 can be retained and stored. For example, when the variation display of the normal pattern display device 41 is suspended for one time, the left normal suspension lamp (on the inner circumference side of the game area) is lit, when it is suspended for two times, the left and right normal suspension lamps are lit, when it is suspended for three times, the left normal suspension lamp blinks and the right normal suspension lamp lights, and when it is suspended for four times, the left and right normal suspension lamps blink. Incidentally, when a game ball newly passes through the through gate 34 during the jackpot state, the variation display for that amount is also suspended.

Further, the variable display device unit 35 is provided with a decorative pattern display device 42 configured by a liquid crystal display device and capable of displaying decorative patterns. The decorative design display device 42 is configured to variably display the decorative design according to the variative display by the first special display device 43a and the second special display device 43b. Further, the display contents of the decorative pattern display device 42 are controlled by a sub-control device 262 and a display control device 45, which will be described later. That is, in the decorative pattern display device 42, the auxiliary display content is determined by the sub-control device 262 based on the command from the main control device 261 so as to correspond to the results displayed on the first special display device 43a and the second special display device 43b, and the display is performed by the display control device 45 based on the determination.

The decorative design display device 42 is provided with, for example, three upper, middle and lower design display areas (upper design display area, middle design display area, and lower design display area). In each design display area, a plurality of types of decorative design (for example, numeric designs with numbers 1 to 9) are sequentially displayed (variably displayed). It is designed to be For example, when the main controller 261 confirms the occurrence of a big win, the first or second special display devices 43a and 43b display corresponding to the big win, and the decorative pattern display device 42 stops displaying the decorative patterns in a combination corresponding to the big win (for example, the same decorative patterns are stopped and displayed on a predetermined effective line in the upper pattern display area, the middle pattern display area, and the lower pattern display area), and the big win state is started.

In addition, when the decorative patterns are stop-displayed in a combination corresponding to a big win, the same decorative patterns are stop-displayed on a predetermined effective line in the upper pattern display area and the lower pattern display area, for example, as a preliminary stage. In this way, the state in which the same symbol is stopped and displayed on a predetermined effective line in the upper symbol display area and the lower symbol display area and the variable display is still performed in the middle symbol display area is the ready-to-win state. Of course, the occurrence of the reach state does not necessarily mean that the jackpot will be won, and there are cases where the win is lost.

In this embodiment, after the occurrence of the ready-to-win state, when the same decorative pattern (ready-to-win pattern) stopped and displayed in the upper and lower pattern display areas is stopped and displayed on the same effective line in the middle pattern display area (when doubles are stopped and displayed), a big win state is given. Also, in the case of an odd number of doublets, "15RS" is generated, and in the case of an even number of doublets, either "15RS" or "15RN" is generated.

In this embodiment, a plurality of performance stages (with different motifs such as backgrounds) are prepared in the decorative design display device 42 as a performance for teaching or suggesting the game mode in which the player is staying. More specifically, there is a “variable probability stage” that indicates staying in the variable probability mode, a “normal stage” that indicates staying in the normal mode, and a “time reduction stage” that indicates staying in the time reduction mode. That is, when '15RS' is won, the game shifts to a 'probability variable stage' after the big win state is ended, and when '15RN' is won, the game shifts to a 'time shortening stage' after the big win state ends. Furthermore, when the variable display of the special display devices 43a and 43b (the variable display of the decorative pattern display device 42) is performed 100 times in the "time shortening stage", the stage shifts to the "normal stage".

In addition, in this embodiment, the fact that the variable display of the special display devices 43a and 43b performed based on the entry of game balls into the starting winning devices 33a and 33b is suspended (that the right to execute the variable display has been obtained) is also taught in the decorative pattern display device 42. For example, in the reserved display area, which is the lower area of the display area of the decorative design display device 42, a reserved icon indicating that the variable display is reserved is displayed.

In addition, a plurality of general prize winning devices 31 (in this example, two on each side) are provided along the periphery of the game area (inner rail component 51) below the left side area and the right side area of the variable display device unit 35. Although details will be described later, the general winning device 31 includes a winning opening switch 221 capable of detecting a game ball entering the general winning opening 31 .

Further, the game board 30 is provided with a rail 50 which is composed of an inner rail component 51 and an outer rail component 52 and guides the game ball shot from the shooting device 60 to the upper part of the game board 30 . As a result, the game ball shot with the rotating operation of the handle 18 is guided into the game area formed between the game board 30 and the glass unit 137 through the shooting rails 61 and 50 .

A return ball preventing member 53 is attached to the tip portion (upper left portion in FIG. 4) of the inner rail constituting portion 51 . As a result, the game ball once guided from the rail 50 to the game area is prevented from returning into the rail 50 again. Moreover, a return rubber 54 is attached to substantially the tip portion (upper right portion in FIG. 4) of the outer rail-constituting portion 52 . A game ball shot with a force greater than or equal to a predetermined amount hits the return rubber 54 and is returned to, for example, the substantially central portion side of the game board 30 .

Further, in the present embodiment, the outer rail forming part 52 ends at the upper right part of the game board 30 and the inner rail forming part 51 ends at the lower right part of the game board 30 . Therefore, the play area is defined by the rails 50 and the inner peripheral surfaces of the window holes 39 of the resin base 38 . However, since the game ball hit by the shooting device 60 may flow backward on the rail 50 until it passes the return ball preventing member 53, the parallel portions of the inner and outer rail constituent portions 51 and 52 are excluded from the game area.

As shown in FIG. 3 , a ball passage unit 70 is provided on the back side of the front frame set 14 below the window portion 101 . The ball passage unit 70 includes a lower tray communication path 71 that connects the payout mechanism 352 to the outlet 16 of the lower tray 15 and an upper tray communication path 73 that connects the payout mechanism 352 to the upper tray 19 . Further, there is a gap of a predetermined interval between the launch rail 61 provided on the front side of the inner frame 12 and the rail 50 (outer rail forming part 52), and the ball passage unit 70 of the front frame set 14 is formed with a foul ball passage 72 for guiding the game ball dropped from the gap to the lower tray 15. As a result, if a game ball shot from the shooting device 60 does not reach the return ball preventing member 53 and travels back along the rail 50 as a foul ball, the foul ball is discharged to the lower tray 15 through the foul ball passage 72.例文帳に追加

Reference numeral 67 in FIGS. 3 and 4 denotes a payout passage for guiding game balls put out by a payout mechanism 352, which will be described later, to the front of the inner frame 12, and is divided into a passage leading to the upper tray communication passage 73 (upper tray 19) and a passage leading to the lower tray communication passage 71 (lower tray 15). A shutter 68 is provided below the pay-out passage 67, and when the front frame set 14 is opened, the shutter 68 protrudes forward due to the urging force of a spring or the like to substantially close the outlet of the pay-out passage 67. - 特許庁Further, when the front frame set 14 is closed, the shutter 68 is pushed open by the inlet-side rear end of the lower tray communication passage 71 . The entrances (ball inflow portions) of the lower tray communicating path 71 and the upper tray communicating path 73 are adjacent to each other, and the entrances and the payout path 67 are separated by a predetermined distance when the front frame set 14 is closed, and a game ball can pass through the gap between them. Therefore, when the upper tray 19 and the upper tray communication path 73 are filled with game balls, the put-out game balls flow toward the lower tray communication path 71 side (overflow to the inlet side of the lower tray communication path 71) and are put out to the lower tray 15 through the lower tray communication path 71.例文帳に追加

In addition, the ball passage unit 70 is provided with a full detection switch (not shown) for detecting game balls positioned in the lower tray communication passage 71 . Due to the presence of the full detection switch, it can be grasped that the lower tray 15 is full of game balls (that the lower tray 15 is full of game balls and that the game balls are staying in the lower tray communication passage 71). In this embodiment, based on the detection of game balls continuously for a predetermined period of time by the full detection switch, an error notification is controlled to teach that the lower tray 15 is full using the display and sound of the decorative pattern display device 42. In addition, when the retention of the game ball in the lower tray communication passage 71 is eliminated and the game ball is no longer detected by the full detection switch (when the game ball is no longer detected continuously for a predetermined time), the error notification state is canceled.

Next, the rear configuration of the pachinko machine 10 will be described with reference to FIGS. 5 and 6. FIG. Various control boards are arranged vertically and horizontally on the rear surface of the pachinko machine 10, and some of them are arranged so as to be overlapped in the front and rear directions. Since the dispensing mechanism and the protective cover are integrated as one unit, and the resin portion is generally called the back pack, the unit is called "back pack unit 203" here.

First, the rear configuration of the game board 30 will be described. As shown in FIG. 6, on the rear side of the variable display unit 35 (see FIG. 4) disposed corresponding to the through hole in the center of the game board 30, a resin frame cover 213 is provided to cover the center frame 47 from behind and protrude backward. Further, on the rear side of the frame cover 213, a decorative pattern display device 42, a display control device 45, and a sub-control device 262, which are liquid crystal display devices facing forward from the opening of the frame cover 213, are detachably attached in a state of being stacked in the front-rear direction.

The decorative pattern display device 42 is housed in a housing box 42a formed with an opening for exposing a display part (liquid crystal screen) of the decorative pattern display device 42 to the front side of the pachinko machine 10 and fixed to the rear side of the frame cover 213. The display control device 45 is housed in a substrate box 45a and fixed to the back side of the decorative pattern display device 42 (housing box 42a). The sub-controller 262 is accommodated in a substrate box 262a and fixed to the rear side of the display control device 45 (substrate box 45a). An LED control board or the like for driving the LED or the like built in the center frame 47 is arranged inside the frame cover 213 . The storage box 42a and the substrate boxes 45a and 262a are made of a transparent resin material or the like so that the inside can be visually recognized.

Below the frame cover 213, a back frame set 215 is attached to the game board 30 so as to cover the general winning port 31, variable winning device 32, starting winning units 33a and 33b, etc. from behind. The back frame set 215 is provided with a ball recovery mechanism (not shown) for recovering game balls that have entered various winning slots. The game balls collected by this ball collecting mechanism are guided to a discharge passage portion 217 which will be described later, and discharged to the outside of the pachinko machine 10 from a discharge chute of the discharge passage portion 217 .

Also, in this embodiment, the back frame set 215 functions as a mounting base for the main controller 261 . More specifically, a substrate box 263 having a main controller 261 mounted thereon is rotatably pivoted to the back frame set 215 and can be opened rearward.

The main controller 261 is housed in a substrate box 263 made of transparent resin material or the like. The board box 263 includes a box base and a box cover that covers the opening of the box base, and these box base and box cover are connected by a sealing member. The circuit board box 263 connected by the sealing member is configured so that it cannot be opened unless a predetermined trace is left. As a result, it is possible to easily discover that the board box 263 has been illegally opened.

In addition, the game board 30 is provided with ball entry detection switches for detecting game balls that have entered the various prize winning openings corresponding to the various winning openings such as the general winning opening 31 and the like. Specifically, as shown in FIG. 4 , the general winning opening 31 is provided with a winning opening switch 221 , and the variable winning device 32 is provided with a count switch 223 . Further, the first start winning device 33a and the second start winning device 33b are provided with a first start winning switch 224a and a second start winning switch 224b, and the through gate 34 is provided with a through gate switch 225.

Although not shown, the back frame set 215 is provided with a first board relay board that is electrically connected to the winning slot switch 221, the count switch 223, and the through gate switch 225 via cable connectors. This first board surface relay board relays the winning slot switch 221 and the like and the main controller 261, and is electrically connected to the main controller 261 via a cable connector. On the other hand, the starting prize-winning switches 224a and 224b are directly connected to the main controller 261 via connector cables without passing through the relay board.

The detection results detected by the various incoming ball detection switches are taken into the main controller 261 . Then, a payout command (the number of game balls to be paid out) according to the winning status of each time is transmitted from the main control device 261 to the payout control device 311, and a predetermined number of game balls are paid out based on the output signal from the payout control device 311 (excluding the detection of the through gate switch 225 which does not correspond to the prize balls).
In addition, although not shown, on the rear surface of the game board 30, a solenoid for opening a large winning opening is provided by the variable winning device 32, and a solenoid for opening and closing a pair of opening and closing members 37 is provided by the starting winning unit 33. The back frame set 215 is also provided with a second board relay board (not shown) that relays these solenoids and the main controller 261 .

Next, the configuration of the back pack unit 203 will be described. As shown in FIG. 5, the back pack unit 203 is formed by integrating a resin-molded back pack 351 and a game ball payout mechanism 352 . The back pack unit 203 is supported so as to be openable and closable with respect to the left side (the right side in FIG. 5) of the inner frame 12, and can be opened rearward about the opening/closing axis extending along the vertical direction. In addition, an external terminal plate 240 is provided on the upper left portion of the back pack unit 203 (upper right portion in FIG. 5).

The external terminal board 240 is for relaying transmission of various kinds of information to a game hall computer or the like, and is provided with a plurality of external connection terminals. Terminals for outputting information on the current gaming state (jackpot state, probability variable mode, etc.), terminals for outputting information on the opening of the front frame set 14 and the inner frame 12 detected by the open detection switches 91 and 92 described later, terminals for outputting information on various error states such as ball entry error, lower tray full error, tank no ball error, payout error, and terminals for outputting information on the number of prize balls paid out from the payout control device 311. etc. are provided.

The back pack 351 is integrally formed of, for example, ABS resin, and has a protective cover portion 354 that protrudes rearward from the pachinko machine 10 and has a substantially rectangular parallelepiped shape. The protective cover portion 354 has a shape in which left and right side surfaces and an upper surface are closed and only a lower surface is opened, and has a size sufficient to cover at least the frame cover 213 . However, in this embodiment, the protective cover portion 354 is configured to cover the upper portion and the right portion (the left portion in FIG. 5) of the board box 263 as well. As a result, when the back pack unit 203 is closed, the sealing member provided on the right side of the board box 263 and the terminal section (board side connector) provided along the upper edge of the main controller 261 are covered.

The dispensing mechanism section 352 is arranged so as to bypass the protective cover section 354 . Namely, above the protective cover portion 354, a tank 355 which opens upward is provided, and the tank 355 is sequentially replenished with game balls supplied from the island facilities of the game hall. Below the tank 355 is connected a tank rail 356 having, for example, two rows of ball passages in the horizontal direction and gently sloping toward the downstream side. A payout device 358 is provided at the most downstream portion of the case rail 357, and payout of the required number of game balls is appropriately performed by a predetermined electrical configuration such as a payout motor. The game balls paid out from the payout device 358 are supplied to the upper tray 19 and the like.

The payout mechanism unit 352 is provided with a payout relay board 381 for relaying a payout command signal from the payout control device 311 to the payout device 358, and a power switch board 382 for inputting main power from the outside. The power switch board 382 is supplied with a main power supply of, for example, 24 V AC via a voltage converter, and is turned on or off by a switching operation of the power switch 382a.

Below the back pack unit 203 (board box 263), a lower frame set 251 that is pivotally supported by the left side (the right side in FIG. 5) of the inner frame 12 and that can be opened rearward is provided. As shown in FIG. 6, the lower frame set 251 is formed with a discharge passage portion 217 into which game balls collected by the ball collecting mechanism described above flow in, and at the most downstream portion of the discharge passage portion 217, a discharge chute (not shown) for discharging game balls to the outside of the pachinko machine 10 is formed. In other words, the game balls that have won the prize-winning openings such as the general prize-winning opening 31 are collected via the ball recovery mechanism of the back frame set 215 and discharged to the outside of the pachinko machine 10 through the discharge chute of the discharge passage portion 217 . Incidentally, the out port 36 is similarly connected to the discharge passage portion 217, and the game balls that do not win in any of the prize winning ports are also discharged to the outside of the pachinko machine 10 through the discharge chute. In this embodiment, the back pack unit 203 and the lower frame set 251 are configured as separate bodies and can be opened and closed independently, but the back pack unit 203 and the lower frame set 251 may be integrally formed.

Also, as shown in FIG. 5, on the back side of the lower frame set 251, a payout control device 311, a firing control device 312, a power supply device 313, and a card unit connection board 314 are detachably attached in a state of being superimposed on each other.

The firing control device 312 and the power supply device 313 are housed in a board box 313 a and fixed to the back side of the lower frame set 251 . For the sake of convenience, the launch control device 312 and the power supply device 313 are described as independent control devices, but they are actually configured by one substrate (printed circuit board).

Also, the payout control device 311 is housed in the board box 311a and fixed to the back side of the board box 313a (the firing control device 312 and the power supply device 313). The board box 311a housing the dispensing control device 311 is provided with a sealing member in the same manner as the board box 263 housing the above-described main control device 261, so that a trace of opening the board box 311a remains.

In addition, the card unit connection board 314 is housed in a board box 314a and fixed to the rear side of the board box 313a (the firing control device 312 and the power supply device 313). The board boxes 311a, 313a, and 314a are made of a transparent resin material or the like so that the inside can be visually recognized.

Also, the payout control device 311 is provided with a state return switch 321 projecting outward from the substrate box 311a. For example, when the state recovery switch 321 is pressed when a payout error such as a ball clogging occurs in the payout motor, the payout motor is rotated forward or reverse to clear the ball jam (return to normal state).

Further, the power supply device 313 is provided with a RAM erase switch 323 projecting outward from the board box 313a. This pachinko machine 10 has a backup function, and can retain the state at the time of power failure even when power failure occurs, and can be restored to the state at the time of power failure when recovering from the power failure (recovery of power). Therefore, when the power is cut off in a normal procedure (for example, at the end of business of the game hall), the state before the power cutoff is memorized and held, so that the power is turned on while pressing the RAM erasing switch 323 when the initial state is to be restored when the power is turned on.

Further, as shown in FIG. 6, a locking device 600 is provided on the rear side of the right side portion of the inner frame 12 . The locking device 600 includes a cylinder lock 700 (see FIG. 1, etc.) exposed on the front side of the front frame set 14. A key is inserted into the keyhole of the cylinder lock 700 and rotated in one direction to unlock the inner frame 12. By rotating in the other direction, the front frame set 14 can be unlocked. In this embodiment, inner frame 12 is locked to outer frame 11 and front frame set 14 is locked to inner frame 12 .

As described above, the right side frame forming portion 11d of the outer frame 11 is formed with the extending wall portion 83 that covers the entire upper and lower sections corresponding to the locking device 600 from the rear side of the inner frame 12 (see FIG. 5). As a result, it becomes difficult to insert a wire or the like from the back side of the outer frame 11 and operate the locking device 600 with the wire or the like. As a result, the defense performance can be improved. Furthermore, the extending wall portion 83 is configured to cover the right end portion (the left end portion in FIG. 5) of the back pack unit 203 and the lower frame set 251 from the back side, and in the closed state of the inner frame 12, the back pack unit 203 and the lower frame set 251 cannot be opened.

Further, as shown in FIG. 4, a front frame open detection switch 91 for detecting the opening of the front frame set 14 is provided at the lower right portion of the front side of the inner frame 12 (on the right side of the launching device 60), and as shown in FIG. The front frame open detection switch 91 and the inner frame open detection switch 92 each have a detection part that can be retracted with respect to the switch body part, the front frame open detection switch 91 is provided so that the detection part faces forward, and the inner frame open detection switch 92 is provided so that the detection part faces backward. When the detector is in a state of protruding from the switch body, an ON signal is output to the main controller 261, and when the detector is pushed toward the switch body and retracted into the switch body, an OFF signal is output to the main controller 261. That is, when the front frame set 14 is closed, the detection part of the front frame open detection switch 91 is turned off by being pressed by the back surface of the front frame set 14, and when the front frame set 14 is opened, the detection part returns to the projected state and is turned on. Similarly, when the inner frame 12 is closed, the inner frame open detection switch 92 is turned off when the detection portion is pressed by the pressing portion 86 integrally formed with the receiving portion 85 of the outer frame 11, and when the inner frame 12 is opened, the detection portion returns to the projected state and is turned on.

Next, the electrical configuration of the pachinko machine 10 will be described. FIG. 7 is a block diagram showing the electrical configuration of the pachinko machine 10. As shown in FIG. A main controller 261 (main substrate) as main control means is equipped with a CPU 501 as a one-chip microcomputer as an arithmetic device. The CPU 501 includes a ROM 502 that stores various control programs and fixed value data to be executed by the CPU 501, a RAM 503 that temporarily stores various data when executing the control programs stored in the ROM 502, and various circuits such as an interrupt circuit, a timer circuit, and a data transmission/reception circuit. However, the CPU, ROM, and RAM may not be formed into one chip, but may be formed into chips for each function.

The RAM 503 includes a stack area that stores the contents of the internal registers of the CPU 501 and the return address of the control program executed by the CPU 501, a work area (work area) that stores various flags, counters, and I/O values, and a backup area 503a.

In addition, the RAM 503 is configured to retain (back up) data by being supplied with a backup voltage from the power supply device 313 even after the pachinko machine 10 is turned off, and all the data stored in the stack area, work area and backup area 503a are backed up.

The backup area 503a is an area for storing the values of the stack pointer, each register, I/O, etc. at the time of power-off (including power failure, hereinafter the same) in order to restore the state of the pachinko machine 10 to the state before the power-off when the power is turned on again when the power is cut off due to the occurrence of a power failure or the like. Writing to the backup area 503a is executed by the main process when the power is turned off, and conversely, restoration of each value written to the backup area 503a is executed by the main process when the power is turned on (including when the power is turned on due to the cancellation of a power failure; the same shall apply hereinafter). The NMI terminal (non-maskable interrupt terminal) of the CPU 501 is configured to receive a power failure signal SK1 output from a power failure monitoring circuit 542, which will be described later, when the power is shut off due to a power failure or the like.

If at least the data stored in the stack area and the backup area 503a are backed up, it is not necessary to back up the data stored in all areas. For example, the data stored in the stack area and the backup area 503a may be backed up, and the data stored in the work area may not be backed up.

An input/output port 505 is connected to the CPU 501 containing the ROM 502 and RAM 503 via a bus line 504 including an address bus, a data bus, and the like. Connected to the input/output port 505 are a RAM erasure switch circuit 543, a payout control device 311, a sub-control device 262, first and second special display devices 43a and 43b, a normal symbol display device 41, a first and second reservation display devices 46a and 46b, a normal reservation display device 44, and the like. With this configuration, the above-described special display devices 43a and 43b and the normal symbol display device 41 are directly controlled by the main control device 261. FIG. On the other hand, the decorative pattern display device 42 is controlled via the sub-control device 262 .

In addition, although illustration of various relay boards and the like is omitted for convenience, the input/output port 505 is connected to various detection switches such as the winning port switch 221, the count switch 223, the starting winning unit switches 224a and 224b, the through gate switch 225, and various switches of the handle 18, and various electrical components such as various boards and solenoids for opening and closing the variable winning device 32. In other words, the main controller 261 is provided with a plurality of terminal portions (board-side connectors) for connecting connectors of various cable connectors.

The sub-control device 262 (sub-control board) as a sub-control means includes a CPU 551 which is an arithmetic device, a ROM 552 which stores various control programs and fixed value data to be executed by the CPU 551, a RAM 553 which is a memory for temporarily storing various data when executing the control program stored in the ROM 552, an input/output port 554, and a bus line 555. The RAM 553 is a memory that temporarily stores work data and flags used when various programs are executed by the CPU 551 .

The input/output port 554 is connected to the CPU 551 , the ROM 552 and the RAM 553 via a bus line 555 and also to the display control device 45 . Further, the input/output port 554 is connected with the speaker SP, the hold lamps 46a and 46b, the performance button 125, various illumination parts and the lamps 102-104.

The CPU 551 of the sub control device 262 causes the display control device 45 to execute display control based on, for example, a command signal (for example, a variation pattern command) transmitted from the main control device 261, and causes the decorative pattern display device 42 to display. As described above, in the present embodiment, the first and second special display devices 43a and 43b controlled by the main control device 261 are adapted to display that the player has won the jackpot, and the decorative design display device 42 controlled by the sub-control device 262 performs display (incidental effect display) in accordance with the display of the special display devices 43a and 43b. In addition, a gaming machine ID is stored in the ROM 552 of this embodiment.

The payout control device 311 controls the payout of prize balls and rental balls by the payout device 358 . A CPU 511, which is an arithmetic device, includes a ROM 512 storing control programs executed by the CPU 511, fixed value data, and the like, and a RAM 513 used as a work memory and the like.

The RAM 513 of the payout control device 311, like the RAM 503 of the main control device 261, includes a stack area in which the contents of the internal register of the CPU 511 and the return address of the control program executed by the CPU 511 are stored, a work area (work area) in which values such as various flags, counters, and I/O are stored, and a backup area 513a.

The RAM 513 is configured to retain (back up) data by being supplied with a backup voltage from the power supply device 313 even after the pachinko machine 10 is turned off, and all the data stored in the stack area, work area and backup area 513a are backed up. If at least the data stored in the stack area and the backup area 513a are backed up, it is not necessary to back up the data stored in all areas. For example, the data stored in the stack area and the backup area 513a may be backed up, and the data stored in the work area may not be backed up.

The backup area 513a is an area for storing the values of the stack pointer, each register, I/O, etc. at the time of power-off in order to restore the state of the pachinko machine 10 to the state before the power-off when the power is turned on again when the power is cut off due to the occurrence of a power failure or the like. Writing to the backup area 513a is executed by the main process when the power is turned off, and restoration of each value written to the backup area 513a is executed by the main process when the power is turned on. As with the CPU 501 of the main control device 261, the NMI terminal of the CPU 511 is also configured to receive a power failure signal SK1 from the power failure monitoring circuit 542 when power is shut off due to a power failure or the like. When the power failure signal SK1 is input to the CPU 511, NMI interrupt processing as power failure processing is immediately executed.

A work area is provided with a payout permission flag for setting the payout permission of prize balls by the payout control device 311, a command reception flag set when a command transmitted from the main control device 261 is received, and a command buffer for storing the command transmitted from the main control device 261. - 特許庁

The payout permission flag is a flag for setting the payout permission of prize balls, and is turned on when a specific command permitting the payout of prize balls is transmitted from the main control device 261 and the specific command is received, and is turned off when the initial setting process or the state before the power shutdown is restored. In this embodiment, the specific commands are a payout initialization command that instructs the initialization process of the RAM 513 of the payout control device 311, a prize ball command that instructs the payout of prize balls, and a payout return command that is transmitted when the main control device 261 is restored.

The command reception flag is a flag for confirming whether or not the payout control device 311 has received a command, and is turned on when any command is received. Similar to the payout permission flag, it is turned off when the initial setting process or before the power is turned off, and is turned off when the received command is judged by the command judgment process.

The command buffer consists of a ring buffer that temporarily stores commands sent from the main controller 261 . The ring buffer has a prescribed storage area, stores commands with regularity from the start end to the end of the storage area, and is configured to return to the start end of the storage area and update the command when the commands are stored in all the storage areas. Therefore, when a command is stored and read, the store pointer and read pointer in the command buffer are updated, and the command is stored and read based on each pointer.

An input/output port 515 is connected to the CPU 511 containing the ROM 512 and RAM 513 via a bus line 514 comprising an address bus and a data bus. The input/output port 515 is connected to the RAM erasing switch circuit 543, the main controller 261, the firing controller 312, the dispensing device 358, and the like.

The card unit connection board 314 is electrically connected to a ball lending operation section (ball lending button 121 and return button 122) on the front of the pachinko machine 10 and a card unit (ball lending unit) arranged on the side of the pachinko machine 10 in a game hall or the like, and takes in a ball lending operation command by the player and outputs it to the card unit. Note that the card unit connection board 314 may be omitted in a cash machine in which game balls are directly lent to the upper tray 19 from a ball lending device or the like without going through the card unit.

The shooting control device 312 permits or prohibits shooting of game balls by the shooting device 60, and the shooting device 60 is allowed to be driven when predetermined conditions are met. Specifically, the shooting device 60 is driven and the game ball is shot with an intensity corresponding to the amount of operation of the handle 18, provided that a firing permission signal is output from the payout control device 311, that the sensor signal detects that the player is touching the handle 18, and that the firing prohibition button 18a (see FIG. 1) for stopping firing is not operated.

The display control device 45 follows the instruction from the sub-controller 262 and executes the variable display of the decorative design in the decorative design display device 42 . The display control device 45 includes a CPU 521, a program ROM 522, a work RAM 523, a video RAM 524, a character ROM 525, a video display processor (VDP) 526, an input port 527, an output port 529, and bus lines 530 and 531. An input/output port 554 of the sub-controller 262 is connected to the input port 527 . Also, the CPU 521 , program ROM 522 , work RAM 523 and VDP 526 are connected to the input port 527 via the bus line 530 . An output port 529 is connected to the VDP 526 via a bus line 531, and the output port 529 is connected to the decorative pattern display device 42, which is a liquid crystal display device.

The CPU 521 of the display control device 45 receives the display command transmitted from the sub-control device 262 via the input port 527, and analyzes the received command or performs predetermined arithmetic processing based on the received command to control the VDP 526 (specifically, to generate an internal command for the VDP 526). Thereby, display control in the decorative pattern display device 42 is performed.

The program ROM 522 is a memory that stores various control programs and fixed value data executed by the CPU 521, and the work RAM 523 is a memory that temporarily stores work data and flags used when the CPU 521 executes various programs.

The video RAM 524 is a memory for storing display data to be displayed on the decorative design display device 42. By rewriting the content of the video RAM 524, the display content of the decorative design display device 42 is changed. The character ROM 525 is a memory for storing character data such as designs displayed on the decorative design display device 42 .

The VDP 526 is a kind of drawing circuit that directly operates the LCD driver (liquid crystal driving circuit) incorporated in the decorative pattern display device 42 . Since the VDP 526 is made into an IC chip, it is also called a "drawing chip", and its substance should be called a microcomputer chip containing firmware dedicated to drawing processing. The VDP 526 adjusts the timing of each of the CPU 521, the video RAM 524, etc., and intervenes in the reading and writing of data.

In addition, the power supply device 313 includes a power supply unit 541 that supplies power to each part of the pachinko machine 10, a power failure monitoring circuit 542 that monitors power interruption due to power failure, etc., and a RAM deletion switch circuit 543 that is connected to the RAM deletion switch 323.

The power supply unit 541 supplies necessary operating power to each of the main control device 261, the payout control device 311 and the like through a power supply path (not shown). As an overview, the power supply unit 541 takes in an AC 24 volt power supply supplied from the outside, and generates +12V power supply for driving various switches and motors, +5V power supply for logic, backup power supply for RAM backup, etc., and supplies these +12V power supply, +5V power supply and backup power supply to the main control device 261 and the payout control device 311. An operating power source (+12V power source, +5V power source, etc.) is supplied to the launch control device 312 via the payout control device 311 . Similarly, various switches, motors, and the like are supplied with operating power through the control device to which they are connected.

The power failure monitoring circuit 542 is a circuit that outputs a power failure signal SK1 to each NMI terminal of the CPU 501 of the main controller 261 and the CPU 511 of the payout controller 311 when the power is shut off due to power failure or the like. The power failure monitoring circuit 542 monitors the voltage of stable DC 24 volts, which is the maximum voltage output from the power supply unit 541, determines that a power failure (power failure) has occurred when this voltage becomes less than 22 volts, and outputs a power failure signal SK1 to the main controller 261 and the payout controller 311. By the output of this power failure signal SK1, the main control device 261 and the payout control device 311 recognize the occurrence of power failure and execute power failure processing (NMI interrupt processing).

The power supply unit 541 is configured to maintain the output of 5 volts, which is the driving voltage of the control system, at a normal value for a period of time sufficient for executing the power failure processing even after the stable 24 volts of direct current becomes less than 22 volts. Therefore, the main control device 261 and the payout control device 311 can normally execute and complete the power failure processing.

The RAM erase switch circuit 543 is a circuit that takes in the switch signal of the RAM erase switch 323 and clears the backup data of the RAM 503 of the main controller 261 and the RAM 513 of the payout controller 311 according to the state of the switch 323 . When the RAM erasing switch 323 is pressed, the RAM erasing switch circuit 543 outputs a RAM erasing signal SK2 to the main controller 261 and the payout controller 311. When the power of the pachinko machine 10 is turned on with the RAM erasing switch 323 pressed (including power-on due to power failure cancellation), the data in the RAMs 503 and 513 of the main controller 261 and payout controller 311 are cleared.

Now, as shown in FIGS. 8 and 9, in this embodiment, a board replacement unit 404 including a base 405 forming part of the game board 30 and game nails 406 attached to the base 405 is provided. That is, the game board 30 of this embodiment is composed of a game board body 401 formed with a through hole 402 and the like for mounting the variable display unit 35, and a base part 405 attached while being inserted into a base part opening 403 formed by partially expanding the through hole 402. When the game nail 406 of the board replacement unit 404 is damaged, the game nail 406 is replaced together with the base portion 405 (part of the game board 30). 8, illustration of the game nail 406 and the like of the game board main body 401 is omitted.

The game board main body 401 and the base portion 405 are made of transparent polycarbonate. For this reason, the game board 30 is harder than the conventional one made of plywood, has an increased force for holding the game nails 406, etc., and is thin. Further, behind the game board 30, an electric decoration member 411 (an electric decoration accessory or the like having a transparent or translucent case body and an LED built in the case body) and decoration accessories are arranged, and the light mode of the electric decoration member 411 and the decoration accessories can be visually recognized through the transparent game board 30. - 特許庁Further, on the rear surface and the front surface of the game board 30, a translucent cel image 412 is attached appropriately.

Further, as shown in FIG. 9, the game nail 406 as a game member includes a columnar body portion 414, a head portion 415 provided on one end side of the body portion 414, and a pointed end portion 416 provided on the other end side of the body portion 414. A helical groove portion 417 is formed in a portion of the body portion 414 on the side of the tip portion 416 and embedded in the game board 30 .

Furthermore, the center frame 47 of the variable display device unit 35 as a specific game member is provided so as to pass through a through hole 402 formed in the game board 30 . In addition, the center frame 47 has mounting pieces 421 projecting outward from the outer periphery of the center frame 47 . The mounting piece 421 is formed with a frame-side mounting hole 423 through which a screw 422 as a mounting member is inserted. The mounting piece 421 is fixed to the game board 30 by a screw 422 while being in contact with the front surface of the game board 30 . The center frame 47 of this embodiment is made of a colored opaque resin material (for example, polycarbonate or the like). Note that the center frame 47 can also be made of a transparent resin material.

In addition, the board surface replacement units 404 are arranged at a plurality of positions corresponding to the game nails 406 with which the game balls collide relatively vigorously and the game nails 406 with which the game balls are frequently contacted among the many game nails 406 arranged in the game area. In other words, the game nail 406 on the route through which the game ball passes frequently receives a large load from the game ball and is likely to be damaged, and if it should be damaged, the impact on the game is great. In this embodiment, there are provided an upper board replacement unit 407 adjacent to the upper left of the variable display device unit 35 (center frame 47), a side board replacement unit 408 provided adjacent to the ball entrance 151 (see FIG. 4) on the left side of the center frame 47, and a lower board replacement unit 409 provided adjacent to and below the variable display unit 35.

In the game of the pachinko machine 10, it is customary to shoot a game ball by striking it against the game peg 406 arranged at the upper left part of the game area, and the game peg 406 of the upper board surface replacement unit 407 is equipped with the game peg 406 with which the game ball hit into the game area is likely to come into contact first. In addition, since the moving path of the game ball in the game area is determined depending on which game nail 406 the game ball hits first and how, the game nail 406 attracts a lot of attention. Furthermore, since the pachinko machine 10 advances the game by entering the game balls into the starting prize winning devices 33a and 33b, the game nail 406 of the lower board face replacement unit 409 for moving the game balls toward the starting prize winning devices 33a and 33b attracts a lot of attention and the contact frequency (passing frequency) of the game balls is relatively high. In addition, if the game nail 406 of the horizontal board surface replacement unit 408 is bent, the ease with which the ball can be entered into the ball entrance 151 of the warp flow path 152 is greatly changed, so that the game nail 406 attracts a relatively high degree of attention. In addition, the game nail 406, which has a high frequency of contact with the game ball and is positioned at an important point in the movement path of the game ball, is relatively frequently adjusted to be straightened when it is bent.

Also, the base portion 405 has the same thickness as the game board main body 401 . Further, the base portion 405 is formed with pilot holes 431 at positions where the game nails 406 are arranged, in the same manner as the game board main body 401 . In addition, the base portion 405 includes a mounting portion 432 that is attached to the center frame 47 using a screw 422 as a mounting member, and a positioned portion 435 that is positioned in the front-rear direction by coming into contact with a positioning portion 425 formed on the inner peripheral surface of the base portion opening 403 of the game board main body 401.

The positioning portion 425 of the game board main body 401 has a substantially triangular convex cross-sectional shape with a top portion positioned rearward of the central portion in the thickness direction of the game board main body 401 and forward of the rear surface of the game board main body 401 . In this embodiment, the positioning portion 425 is formed over the entire inner peripheral surface of the base portion opening 403 .

On the other hand, the positioned portion 435 of the base portion 405 has a substantially triangular recessed cross section that fits with the positioning portion 425 . Further, the positioned portion 435 is formed over the entire outer peripheral surface of the base portion 405, which is substantially rectangular in plan view, and faces the positioning portion 425 (the entire surface other than the surface that abuts against the center frame 47).

In this embodiment, the upper board surface replacement unit 407 and the side board surface replacement unit 408 correspond one-to-one with the base opening 403, and are positioned over the entire inner peripheral surface of the base opening 403 by the positioning section 425. Therefore, when the base portions 405 of the upper board surface replacement unit 407 and the side board surface replacement unit 408 are fitted into the base portion openings 403, the base portions 405 are positioned in the through holes 402, and then inserted into the corresponding base portion openings 403 while being slid parallel to the game board main body 401.

In addition, the lower board surface replacement unit 409 is composed of a left part 409a, a center part 409b, and a right part 409c, and positioning is also performed with respect to the mating surface (of the base portion 405) between the left part 409a and the center part 409b and the mating surface (of the base portion 405) between the center part 409b and the right part 409c. More specifically, the left part 409a and the right part 409c are the same, and the base part 405 thereof has a substantially rectangular shape (trapezoidal shape) when viewed from the front. A base portion 405 of the central part 409b has a substantially V-shape in front view, and a concave positioned portion 435 is formed on the lower surface corresponding to the opening portion 403 for the base portion. Furthermore, the mating surfaces of the left part 409a, the right part 409c, and the central part 409b are formed with recesses or projections that fit one into the other. Therefore, in the lower board surface replacement unit 409, with the left part 409a and the right part 409c installed in the base part opening 403, the central part 409b is inserted from the through hole 402 side into the base part opening 403 between the left part 409a and the right part 409c.

A mounting portion 432 of the base portion 405 is a portion of the base portion 405 on the mating surface side with the center frame 47. The mounting portion 432 is formed with a base-side mounting hole 433 into which a screw 422 as a mounting member is screwed. In addition, of the outer peripheral surface of the base portion 405, the surface facing the inner peripheral side of the through hole 402 and facing the outer peripheral surface of the center frame 47 (the side surface of the mounting portion 432) extends rearward at an angle to the inner peripheral side of the through hole 402.

On the other hand, a portion of the outer peripheral surface of the center frame 47 facing the base portion 405 extends rearward while being inclined toward the inner peripheral side of the through hole 402 (parallel to the side surface of the mounting portion 432). The mounting piece 421 extends outward from the front end of the inclined surface of the center frame 47 .

Then, the center frame 47 is inserted into the through-hole 402 from the front of the game board 30 with the base part 405 of each board replacement unit 404 fitted in the base part opening 403 . After inserting the center frame 47 into the through hole 402 until the rear surface of the mounting piece 421 abuts against the front surface of the base portion 405 and the game board main body 401, the screw 422 is screwed into the base side mounting hole 433 of the mounting portion 432 from the front through the frame side mounting hole 423 of the mounting piece 421. As a result, the board replacement unit 404 and the center frame 47 are connected.

Further, when the center frame 47 is passed through the through-hole 402, the outer peripheral surface (inclined surface) of the center frame 47 and the side surface of the attachment portion 432 of the base portion 405 of the board replacement unit 404 are configured to abut against each other. Further, when the base part 405 is attached to the game board main body 401 and the center frame 47, the rear surface of the base part 405 is flush with the rear surface of the game board main body 401, and the front surface of the base part 405 is flush with the front surface of the game board main body 401.例文帳に追加

The inner peripheral surface of the through hole 402 is also configured to have the same inclination as the side surface of the mounting portion 432 of the base portion 405 . A portion of the outer peripheral surface of the center frame 47 facing the inner peripheral surface of the through hole 402 also extends rearward while being inclined toward the inner peripheral side of the through hole 402 (parallel to the side surface of the mounting portion 432). Therefore, when the center frame 47 is passed through the through hole 402, the outer peripheral surface (inclined surface) of the center frame 47 and the inner peripheral surface of the through hole 402 are configured to abut. The screw 422 connecting the mounting portion 432 of the base portion 405 and the mounting piece 421 of the center frame 47 is the same countersunk screw as the screw 422 for mounting the center frame 47 to the game board main body 401 . Furthermore, the head of the screw 422 is configured to fit within the thickness of the mounting piece 421 .

In addition, for example, a sticker (cel 412) printed with a subtitle of the pachinko machine 10 or a pattern associated with the motif of the pachinko machine 10 is attached to the front surface of the base portion 405 of the upper board replacement unit 407 (see FIG. 9). are Furthermore, the game board main body 401, the upper board surface replacement unit 407, and the side board surface replacement unit 408 are colorless and transparent, while the base part 405 of the lower board surface replacement unit 409 is colored and transparent, so that the light transmittance is slightly lowered. As a result, the degree of backlight in the peripheral portion of the first starting prize winning device 33a is alleviated, and the behavior of the game ball becomes relatively easy to visually recognize.

Further, when the game nail 406 of the board replacement unit 404 is broken, the board replacement unit 404 is replaced. When replacing the board surface replacement unit 404, first, the screws 422 connecting the attachment piece 421 of the center frame 47, the game board main body 401 and the base part 405 are removed, and the center frame 47 is removed from the game board 30. As a result, the base portion 405 of the board replacement unit 404 can be pulled out toward the through hole 402 . Then, the corresponding board replacement unit 404 is removed, and a replacement board replacement unit 404 is attached (the base portion 405 is fitted into the base portion opening 403). After that, the center frame 47 is inserted into the through hole 402 , and the game board main body 401 and the base portion 405 are connected to the mounting piece 421 with screws 422 . As described above, the replacement of the board replacement unit 404 is completed.

If the base part 405 to which the damaged game nail 406 is attached can be reused after removing the damaged game nail 406 (if there is no scar of removal, etc.), it is possible to reuse it by attaching a new game nail 406 again.

Also, the members (frame cover 213, etc.) attached to the rear surface of the game board 30 are attached to the game board main body 401 and are not attached to the base portion 405 (they may come into contact with the rear surface of the base portion 405, but are not fixed by screws or the like). As a result, the board replacement unit 404 can be relatively easily removed from the game board body 401 without removing the member on the rear side of the game board 30 from the game board 30 .

Furthermore, as shown in FIG. 9 , on the rear surface side of the game board 30 , the cell image 412 is attached not only to the rear surface of the game board main body 401 but also to the rear surface of the base portion 405 . However, in this example, the cell image 412 is attached separately to the game board main body 401 and the base portion 405, and by fitting the base portion 405 into the base portion opening 403, the patterns of both cell images 412 are connected (continuously) without a step in the front and back. In addition, there is no member attached between the base portion 405 and the game board main body 401 .

As described in detail above, according to the present embodiment, the board surface replacement unit 404 including the base portion 405 constituting a part of the game board 30 and the game nail 406 provided in the base portion 405 is provided, and when the game nail 406 of the board surface replacement unit 404 is damaged and the game nail 406 is to be replaced, the base portion 405 (part of the game board 30) is replaced. That is, conventionally, when the broken game nail 406 is removed from the game board 30, the game nail 406 left broken inside the game board 30 is hit with a bar-shaped tool from the front side of the game board 30, and the tool is hit with a hammer to push out the broken nail to the rear side of the game board 30.例文帳に追加Furthermore, when a new game nail 406 is attached, the game nail 406 is hammered into the game board 30 with a hammer. For this reason, since a relatively large impact is applied to the game board 30 when the game nail 406 is replaced, the game board 30 is removed from the inner frame 12 and various game members are removed from the game board 30 so that other members of the pachinko machine 10 are not damaged by the impact, and then the game nail 406 is replaced. Therefore, it involves work such as attachment and detachment of various members and attachment and detachment of wiring, which requires a great deal of labor and increases the risk of work mistakes, and there is concern that the game board 30 and the game members may be damaged (by mishandling the hammer), or the game board 30 and the members on the rear side may be dropped and damaged.

In this regard, in the present embodiment, it is not necessary to hit the game nail 406 or the like with a hammer when replacing the game nail 406 . Therefore, by simply removing the center frame 47 from the game board 30, it is possible to replace the game nail 406 even while the game board 30 is attached to the main body (inner frame 12) of the game machine 10. In addition, it is possible to suppress the occurrence of work mistakes, and even if it occurs, the game board 30, the game nail 406, and the game members around them are damaged (for example, by hitting the front surface of the game board 30 and the game nail 406 with a hammer). It can be configured so as not to cause a situation such as damage. As a result, it is possible to improve workability when exchanging the game peg 406 and reduce the risk of damage to the game board 30, the game peg 406, and the like.

Further, the base portion 405 of the board replacement unit has less restrictions on its shape than the game nail 406, and the shape of the attachment portion to the game board main body 401 can be designed relatively freely. In this embodiment, the base portion 405 includes a mounting portion 432 that is attached to the center frame 47 using screws 422, and a positioned portion 435 that is positioned in the front-rear direction by coming into contact with a positioning portion 425 formed on the inner peripheral surface of the base portion opening 403 of the game board 30. Therefore, the game nail 406 of the board surface replacement unit 404 can sufficiently secure the stability in the mounting state to the game board main body 401, and can make the game nail 406 easier to remove from the game board 30 (the game board main body 401) than the game nail 406 directly attached to the game board main body 401, for example. Therefore, when the game nail 406 is removed from the game board 30, the part of the game board 30 where the game nail 406 was attached is damaged. 6 is shifted in a predetermined direction in the prepared hole 431, the position of the game nail 406 is displaced from its original position, etc., and a scar is left to cause deterioration of the design. As a result, the game nail 406 can be replaced accurately and relatively easily, and the accuracy and workability of the replacement of the game nail 406 can be improved.

In particular, in a configuration in which the game board 30 is transparent and the rear side and the inside of the game board 30 are visible through the game board 30, for example, when the game nail 406 is removed from the game board 30, if the rear surface or the inside of the game board 30 is damaged, the damaged part will be visible and there is a concern that the design will be deteriorated. Regarding the game nail 406 of the board surface replacement unit 404, the whole upper board surface replacement unit 407, which is replaced together with the base part 405 to which the game nail 406 is attached, can be relatively smoothly removed from the game board main body 401, so that the connection part (positioning part) between the board surface replacement unit 404 and the game board main body 401 can be prevented from being damaged. Therefore, it is possible to avoid a situation in which a scar or the like formed when the game nail 406 is replaced is visually recognized and causes deterioration of the design.

In addition, the game board 30 made of polycarbonate is harder than the conventional game board made of plywood, and as a result, there is concern that the game nail 406 may be easily broken. In addition, the game board 30 has a strong force for holding the game nail 406, and the task of removing the game nail 406 (broken and left inside the game board 30) from the game board 30 becomes difficult, and there is a fear that the game board 30 will be damaged. In this respect, as in the present embodiment, by providing the board face replacement unit 404 to enable the game nails 406 to be replaced accurately and relatively easily, even if the chances of replacing the game nails 406 increase, sufficient maintenance can be performed.

Furthermore, the rear surface of the base portion 405 attached to the game board main body 401 and the center frame 47 is flush with the rear surface of the game board main body 401 . Therefore, for example, it is possible to avoid a situation in which the base portion 405 protrudes rearward from the rear surface of the game board 30, and the board surface replacement unit 404 hinders the arrangement of various members (various control devices, etc.) provided on the rear surface side of the game board 30 (in this example, the frame cover 213, etc., cannot be attached). In other words, the arrangement of various members provided on the rear surface side of the game board 30 can reduce the situation that the part where the board replacement unit 404 can be installed is limited, and the board replacement unit 404 can be installed at a desired position (due to the arrangement of the various game members on the game area side). Furthermore, the cel image stuck to the rear surface of the game board main body 401 and the cel image stuck to the rear surface of the base part 405 can be made flush with each other, and the visibility of the rear side of the game board 30 viewed through the transparent game board 30 can be improved.

The front surface of the base portion 405 attached to the game board main body 401 and the center frame 47 is flush with the front surface of the game board main body 401 . Therefore, it is possible to prevent the game balls flowing down from above the game nails 406 of the board replacement unit 404 along the front surface of the game board 30 from colliding with the upper surface of the base portion 405 . Therefore, it is possible to avoid problems caused by the game ball colliding with the upper surface of the base portion 405 and being bounced forward (for example, collision with the glass unit 137 in front of the game area to generate noise, or deviation from the winning device (first start winning device 33a) due to a large change in the movement path of the game ball, etc.). Furthermore, it is possible to avoid the situation that the base part 405 is damaged or the mounting state of the base part 405 is adversely affected (the base part 405 and the game nail 406 are tilted, etc.) due to the collision of the game ball with the upper surface of the base part 405. - 特許庁In addition, the formation of a step between the base part 405 and the game board main body 401 can prevent a situation in which the pachinko machine 10 or the game machine maker has a bad impression (whether it is a poor product or not, etc.), or the design is deteriorated.

In addition, since the base portion 405, which is a part of the game board 30, is a separate piece from the game board body 401, it is possible to change the design of the game board 30 at the base portion 405 relatively easily. For example, it is possible to relatively easily increase the variations and functions of the game board 30 by, for example, making it different from the game board main body 401 in color or the like for a predetermined purpose such as marking the target position of the game ball (to draw attention to the main part) or making the game ball easier to see, or integrally forming a part on the rear surface side of the base part 405 to which a predetermined member can be attached, locked, or supported. Therefore, it is possible to improve functionality and design. Also, when changing the model, for example, by replacing the board surface replacement unit, it is possible to relatively easily change the arrangement of game members such as game nails and prize winning openings, and change information means such as model information. In this example, a sticker printed with information unique to the pachinko machine 10 (information that differs depending on the model and indicates the subtitle and the position of the ball entrance 151 of the warp flow path 152 of the center frame 151) is attached to the front surface of the base portion 405 of the upper board surface replacement unit 407 and the side board surface replacement unit 408, and the base portion 405 of the lower board surface replacement unit 409 is colored to suppress light transmittance. (Composed of colored transparent resin).

Further, in this embodiment, the positioning portion 425 of the game board main body 401 having a substantially triangular convex cross section and the positioned portion 435 having a substantially triangular concave cross section of the base portion 405 are used for positioning, thereby preventing the base portion 405 from moving forward and backward relative to the game board main body 401. Therefore, the number of screws 422 used for mounting the board surface replacement unit 404 to the game board main body 401 and the center frame 47 and the installation locations can be reduced, particularly screws for connecting the board surface replacement unit 401 and the game board main body 401 can be eliminated. Therefore, it is possible to improve the attachment/detachment workability of the board surface replacement unit 404, and to suppress deterioration in designability due to visible screws. Moreover, in this embodiment, since the game board main body 401 and the base part 405 are transparent, by using the screw 422 to connect the game board main body 401 and the base part 405, the entire screw 422 (including all the parts embedded in the game board 30) can be visually recognized through the game board 30 (the screw 422 appears to be floating), and it is possible to prevent a situation in which the design is lowered and the feeling of discomfort is caused.

Furthermore, since the positioning portion 425 and the positioned portion 435 have a substantially triangular cross-section, for example, compared to the case where one of the positioning portion and the positioned portion has a substantially rectangular cross-section, when force is applied in the front-rear direction (shear stress acts on the positioning portion 425) to the base portion 405 of the board surface replacement unit 404 or a portion of the game board body 401 adjacent to the base portion 405, the positioning portion 425 and the positioned portion 435 do not move. It is possible to suppress a situation such as damage (breakage). Further, when the positioning portion 425 and the positioned portion 435 are butted against each other, one of the positioning portion 425 and the positioned portion 435 is guided by the slope of the other and relatively displaced to an appropriate position even if the positions in the front-rear direction are not completely matched. Therefore, it is possible to improve the mounting workability of the board replacement unit 404 .

In addition, the positioning portion 425 is formed over the entire inner peripheral surface of the base portion opening 403 , and the positioned portion 435 is configured to contact the entire circumference of the positioning portion 425 to be positioned. Therefore, the positioning between the base portion 405 and the game board main body 401 can be performed more firmly. Further, for example, if a portion of the outer peripheral surface of the base portion 405 facing the inner peripheral surface of the opening portion 403 for the base portion of the game board body 401 is a surface extending in a direction perpendicular to the front surface of the game board 30 (thickness direction of the game board 30) (in the case of a portion other than the positioned portion 435), a gap may be formed at the boundary portion (joint portion) between the surface and the game board body 401 so that the rear side of the game board 30 can be seen. Concerned. In this regard, by using the entire inner circumference of the opening 403 for the base portion of the game board body 401 as the positioning portion 425 and performing positioning with the positioned portion 435 over the entire inner circumference, the positioning portion 425 and the positioned portion 435 overlap in the front-rear direction over the entire inner circumference, so such concerns can be dispelled.

Furthermore, when the positioning portion 425 is formed over the entire inner peripheral surface of the base portion opening 403, the base portion 405 cannot be attached by being relatively displaced in the front-rear direction with respect to the base portion opening 403 of the game board main body 401. can be inserted into the opening 403.

A screw 422 having a head (for example, a countersunk screw) is used to connect the base portion 405 and the center frame 47, and the mounting piece 421 of the center frame 47 is overlapped in front of the base portion 405, and the screw 422 is screwed into the base side mounting hole 433 of the base portion 405 from the front through the frame side mounting hole 423 of the mounting piece 421. Therefore, when the game peg 406 of the board replacement unit 404 is replaced, the screw 422 is screwed into the base portion 405 of the new board replacement unit 404. For example, as in the case where the screw 422 is screwed into the center frame 47 by penetrating the base portion 405 from the base portion 405 side, the frame side mounting hole of the center frame 47 has become loose and the screw 422 is screwed. It is possible to avoid the possibility that the screws cannot be screwed together properly.

Further, since the center frame 47 is made of opaque resin and the screws 422 connecting the center frame 47 and the base portion 405 are provided in the opaque mounting pieces 421, the screws 422 are not so conspicuous. In addition, since the mounting piece 421 of the center frame 47 is positioned in front of the base portion 405 and the screw 422 is mounted from the front, the screw 422 can be screwed while holding the game nail 406 by hand (so as not to drop or shift its position). is planned.

(Second embodiment)
A second embodiment will be described below. As shown in FIGS. 10 and 11, in the second embodiment, a plurality of patterns of variable display units 35 (center frame 47) having different shapes can be attached to the game board 30 (game board main body 442) using a board replacement unit 441. More specifically, as shown in FIG. 10, the game board 30 can be fitted with a center frame 47 (hereinafter referred to as a symmetrical frame 443) that fits in the center of the game board 30 and has a substantially symmetrical front view shape of the game area in which the game ball can move, and a center frame 47 (hereinafter referred to as a right extended frame 444) that extends the symmetrical frame 443 to the right side area of the game area as shown in FIG. Configured. The vertical width of the right extension frame 444 is larger than the vertical width of the symmetrical frame 443 . 10 and 11, illustration of the game nail 456 and the like of the game board body 442 is omitted.

The game board main body 442 is formed with a through hole 445 for mounting the right expansion frame 444. As shown in FIG. In this state, the frame-side mounting hole 447 formed in the mounting piece 446 matches the screw hole 448 formed in the game board main body 442 . The right expansion frame 444 is attached to the game board main body 442 by screwing the screws 449 from the front into the screw holes 448 through the frame-side attachment holes 447 . In this embodiment, when the right expansion frame 444 is mounted on the game board main body 442, the board replacement unit is not used.

On the other hand, as shown in FIG. 10, when a symmetrical frame 443 is mounted on a game board main body 442, a board replacement unit 441 is provided so as to fill the gap formed between the symmetrical frame 443 passed through the through hole 445 and the peripheral edge of the through hole 445. In this embodiment, the gap is filled with two base portions 451 (the base portions 451 of the two board replacement units 441). Hereinafter, such a gap (a portion of the through-hole 445 where the base portion 451 of the board replacement unit 441 is installed) is also referred to as a right extended portion 452 .

As shown in FIGS. 12 and 13, in this embodiment, a positioning portion 453 having a substantially triangular convex cross section is formed over the entire inner peripheral surface of the through hole 445 .

On the other hand, as shown in FIG. 12, a base portion 451 of the board replacement unit 441 is formed with a positioned portion 454 having a substantially triangular recessed cross-section that fits into the positioning portion. The mating surfaces of the base portions 451 of the pair of board surface replacement units 441 are also formed with concave portions or convex portions (similar to the positioning portion 453 and the positioned portion 454) so that one fits into the other.

Then, after the base portions 451 of the two board surface replacement units 441 are fitted in order to the right expanded portion 452, the symmetrical frame 443 is inserted into the through hole 445, and the attachment piece 446 of the symmetrical frame 443 is brought into contact with the game board main body 442 and the front surface of the base portion 451. Further, by connecting the game board main body 442 and the base portion 451 to the attachment piece 446 with the screw 449, the symmetrical frame 443 is attached to the game board 30. FIG.

As shown in FIG. 12, the side surface of the mounting portion 455 of the base portion 451 of the board surface replacement unit 441 is parallel to the front inclined surface of the positioning portion 453 having a substantially triangular convex cross section of the game board main body 442, and extends backward toward the inner peripheral side of the through hole 445. 12 and 13 , of the outer peripheral surfaces of the symmetrical frame 443 and the right extended frame 444, the inner peripheral surface of the through hole 445 (the positioning portion 453 formed in) and the portion of the base portion 451 facing the side surface of the mounting portion 455 extend obliquely in parallel with the front inclined surface of the positioning portion 453 and the side surface of the mounting portion 455 of the base portion 451. In other words, in this embodiment, there is a portion where the positioning portion 453 and the outer peripheral surfaces of the symmetrical frame 443 and the right extended frame 444 face each other.

Further, as shown in FIG. 12, when the symmetrical frame 443 is attached to the game board main body 442, as shown in FIG. 13, among the screw holes 448 for screwing the screws 449 for attaching the right expansion frame 444 to the game board main body 442, those provided around the right expansion portion 452 are unnecessary. In this embodiment, the pilot hole 457 for attaching the game nail 456 formed in the game board main body 442 and the screw hole 448 have the same shape (hole diameter). In other words, the mounting piece 446 of the right expansion frame 444 is formed with a frame side mounting hole 447 aligned with one of the pilot holes 457 to which the game nail 456 is mounted when the symmetrical frame 443 is mounted on the game board main body 442 .

In addition, in this embodiment, the right extended frame 444 corresponds to the first specific game member, and the symmetrical frame 443 corresponds to the second specific game member. Furthermore, the state in which the right expansion frame 444 is mounted on the game board main body 442 corresponds to the first use state, and the state in which the game board main body 442 is mounted with the symmetrical frame 443 corresponds to the second use state. In addition, the frame-side mounting hole 447 corresponds to the member-side mounting hole, and the pilot hole 457 into which the screw 449 for mounting the right expansion frame 444 is screwed among the pilot holes 457 of the game board main body 442 corresponds to the board-side mounting hole.

As described above, in the second embodiment, the game board main body 442 can be shared, and the cost of the game board main body 442 can be reduced and the convenience of management can be improved. Also, when the symmetrical frame 443 is mounted on the game board main body 442, the pilot hole 457 used for attaching the game nail 456 to the game board main body 442 is used, and when the right expansion frame 444 is mounted on the game board main body 442, it is configured to be used as a screw hole 448 into which the screw 449 for attaching the right expansion frame 444 to the game board main body 442 is screwed.

Therefore, when the right expansion frame 444 is mounted, a screw hole 448 for attaching the right expansion frame 444 to the game board main body 442 is separately required (when using the right expansion frame 444, the screw hole 448 is specially opened). In addition, in the game board main body 442, the screw hole 448 for attaching the right expansion frame 444 to the game board main body 442 is not used when the left-right symmetrical frame 443 is mounted (the unused screw hole 448 exists and is visually recognized), thereby avoiding a situation in which a sense of incongruity or the like is caused or a deterioration in design is caused.

Further, in the present embodiment, the outer peripheral surface of the symmetrical frame 443 or the right expansion frame 444, the outer peripheral surface of the base portion 451, and the inner peripheral surface of the through hole 445 are configured such that the angles of the surfaces that face each other are the same, and the surfaces are in contact with each other. Therefore, for example, compared to a configuration in which these are not brought into contact with each other, it is possible to stabilize the mounting state and reduce the risk of damage.

It should be noted that the present invention is not limited to the contents described in the above-described embodiment, and may be implemented as follows, for example.

(a) In the above embodiment, the front surface of the base portion 405 is flush with the front surface of the game board main body 401 , but it may be positioned behind the front surface of the game board main body 401 . Furthermore, in the above embodiment, the rear surface of the base portion 405 is configured to be flush with the rear surface of the game board main body 401, but it may be provided so as to be positioned forward of the rear surface of the game board main body 401.

Further, the base portion 405 of the board replacement unit 404 is attached so as to fit within the thickness of the game board main body 401, but it is not particularly limited to such a configuration. For example, the front surface of the base portion 405 may be formed with decorative unevenness so that the front surface of the base portion 405 partially or entirely protrudes forward from the front surface of the game board main body 401 . Further, for example, a convex portion having a substantially triangular cross section may be formed on the front side of the base portion 405 so that a step in the front-rear direction is not formed between the end edge of the mounting piece 421 of the center frame 47 (so as to form a slope toward the game board body 401). Even if the projecting portion projecting forward from the base portion 405 is integrally formed with the base portion 405, when the game ball cannot pass in front of the projecting portion, the projecting portion corresponds to a game member instead of the base portion.

In addition, the upper part of the base part 405 may be positioned slightly behind the front surface of the game board 30, and the lower part of the base part 405 may be positioned slightly forward of the front surface of the game board 30.例文帳に追加In this case, the boundary between the front face of the game board main body 401 and the front face of the base part 405 is configured such that the upper side is positioned forward, so that it is possible to reliably avoid the formation of a step that the game balls moving from above collide with at the boundary. It should be noted that the portion of the base portion 405 that includes at least the upper side of the front surface is preferably flush with the front surface of the game board main body 401 or located behind the front surface of the game board main body 401 . Here, the "upper side portion of the front surface of the base portion" is intended to be the front side portion of the surface that is visible when the base portion is viewed from above.

Also, on the rear surface side of the base portion 405 , a cable holder for hooking wires may be provided so as to protrude rearward from the rear surface of the game board body 401 . In this case, for example, by providing the cable holder along the arrangement of the game nails, the wiring can be extended along the arrangement of the game nails, and the wiring visually recognized through the base part 405 can be made as inconspicuous as possible by the game nails. Further, on the rear surface side of the base portion 405, locking means for locking a decorative accessory may be provided (for example, a pair of left and right locking pieces and locking claws protruding from the tips of the pair of locking pieces in directions away from each other). In this case, the decorative accessory can be visually recognized through the transparent base portion 405 . The cable holder, locking means, and the like may be formed integrally with the base portion 405, or may be formed separately and attached by locking, press-fitting, screwing, bonding, or the like.

(b) In the above embodiment, the board replacement unit 404 is embodied in which the game nail 406 is attached to the base portion 405, but it may be applied to the board replacement unit 404 in which another game member is attached to the front surface of the base portion 405. For example, the board surface replacement unit 801 shown in FIG. , jump nails). The ball receiving portion 804 is fixed to the base portion 802 on the rear side of the base portion 802 with screws. In this embodiment, the base portion 802 and the ball receiving portion 804 are made of a colorless transparent resin (a sticker (not shown) is attached to the front surface of the ball receiving portion 804). In addition, a portion of the ball receiving portion 804 on the rear side of the base portion 802 is provided with a first start winning switch for detecting a game ball that has entered the ball receiving portion 804 . Note that the ball receiving portion 804 may be integrally formed with the base portion 802 .

Positioned portions 806 having a substantially triangular convex cross section are formed along the left and right side portions and the lower side portion of the base portion 802, and are fitted with positioning portions having a substantially triangular concave cross section formed on the inner peripheral surface of the opening for the base portion of the game board body (not shown). Furthermore, base side mounting holes (not shown) into which screws 808 for mounting the base portion 802 to the mounting pieces 807 of the center frame 47 are screwed are formed near the upper right and upper left corner portions of the base portion 802 . Then, after inserting the base part 802 into the opening part for the base part so as to fit the positioned part 806 to the positioning part, the center frame 47 is inserted from the front through the through hole of the game board main body (not shown), and the mounting piece 807 of the center frame 47 is brought into contact with the front surface of the base part 802. In this state, the frame-side mounting hole (not shown) formed in the mounting piece 807 through which the screw 808 is inserted is aligned with the base-side mounting hole of the base portion 802, so the screw 808 is screwed into the base-side mounting hole through the frame-side mounting hole from the front mounting piece 807 side. As a result, the board replacement unit 801 and the center frame 47 are connected.

In addition, as the game member of the board replacement unit 404, other game members such as the pinwheel nail, the through gate 34, the starting winning device 33b, the variable winning device 32, etc. may be applied. Furthermore, it is also possible to appropriately set combinations when a plurality of types of game members are mounted on one base portion 405 .

Further, when a prize winning device is adopted as a game member, the base portion 802 to which the ball receiving portion is attached is formed in a disk shape, and the base portion 802 is provided rotatably with respect to the game board body (the positioning portion and the positioned portion are configured like rails extending in an arc), and may be configured to continue rotating when the pachinko machine 10 is powered on (or when a predetermined winning state occurs). A game ball entered when the opening of the ball receiving part faces upward is guided to the rear of the base part 802, and the game ball may be detected by an entering ball detection switch provided in a receiving passage for receiving the game ball flowing from the ball receiving part whose opening faces upward. Further, as for the shape of the game board main body when adopting such a configuration, for example, an opening for the base portion into which the base portion 802 mounted with the winning device can be inserted, and a communicating portion for communicating between the opening for the base portion and the through hole are formed (configured in a shape like a part of an elongated hole), a positioning portion is formed on the entire inner surface of the opening for the base portion and the communicating portion, and a base for mounting the winning device is formed on the entire inner surface of the opening for the base portion and the communicating portion from the through hole side via the communicating portion. After the part 802 is inserted, the base part of the board replacement unit corresponding to the communication part, which has a shape that fits the communication part, constitutes a part of the game board 30, and is also provided with game nails, is inserted into the communication part from the side of the through hole. The base portion of the communicating portion corresponding board surface replacement unit is formed with a positioned portion for fitting the positioning portion of the communicating portion, and a supporting portion having the same cross-sectional shape as the positioning portion of the base opening portion for rotatably supporting the positioned portion formed on the outer periphery of the base portion 802 on which the winning device is mounted. By connecting the base portion of the board replacement unit corresponding to the communication portion to the center frame 47 with a screw, the base portion 802 with the prize winning device mounted thereon is rotatably attached. By adopting such a configuration, the base of the configuration that rotates with respect to the game board 30 can be flush with the front surface of the game board 30 . Further, by forming a communicating part between a base opening for accommodating a base part 802 mounted with a prize winning device and an insertion hole of a center frame 47, and providing a board surface changing unit corresponding to the communicating part corresponding to the communicating part, the installation position of the board face changing unit mounted with the winning device can be relatively freely set.

(c) In the above embodiment, the board replacement unit 404 is provided adjacent to the center frame 47, but it may be provided adjacent to other specific game members attached to the opening formed in the game board 30. The starting winning devices 33a and 33b, the variable winning device 32, and the like can be embodied as the board replacement unit 404, and can also be embodied as specific game members.

Further, in the above-described embodiment, the positioned portion 435 is formed in the base portion 405 to perform positioning with the positioning portion 425 formed on the inner peripheral surface of the base portion opening 403, and the board surface replacement unit 404 and the center frame 47 are connected by the screws 422, but the configuration is not particularly limited to this.

(c-1) For example, the base portion 812 of the board replacement unit 811 shown in FIG.

Correspondingly, the game board main body 817 is formed with a base opening 821 composed of a main housing portion 818 for housing the main body portion 814 and a flange housing portion 819 for housing the flange portion 815 . The base portion 812 is attached to the game board main body 817 by inserting the base portion 812 into the base portion opening 821 and screwing the screw 822 into the prepared hole 823 of the game board main body 817 through the mounting hole 816 .

When the board surface replacement unit 811 is attached to the game board main body 817, the front surface of the base part 812 is flush with the front surface of the game board main body 817, and the rear surface of the base part 812 is flush with the rear surface of the game board main body 817. Further, the screws 822 (countersunk screws) connecting the base portion 812 and the game board main body 817 are also configured so as not to protrude rearward from the rear surface of the game board main body 817 .

As described above, by attaching the board surface replacement unit 811 to the game board main body 817 only with the screw 822, the board surface replacement unit 811 can be attached independently even at a position not adjacent to the specific game member attached to the opening of the game board 30 such as the center frame 47. In addition, since the screw 822 for attaching the board replacement unit 811 to the game board body 817 is attached from the rear side of the game board 30, the game board body 817 and the base part 812 are transparent, but the screw 822 can be made inconspicuous compared to the case where the screw 822 is attached to the front side. Furthermore, since the flange part 815 is located on the rear side of the game board 30, the area of the base part 812 on the front side of the game board 30 can be minimized, and the possibility that the game ball hits the boundary part between the base part 812 and the game board main body 817 and changes its traveling direction (forward) can be reduced.

(c-2) Further, for example, as shown in FIGS. 16 and 17, it may be embodied in a board replacement unit 832 having only one game nail 831 mounted thereon. More specifically, as shown in FIGS. 16(a) and 17, the base portion 833 of the board face changing unit 832 has a cylindrical shape having a nail hole 834 for attaching the game nail 831 in the central portion thereof. A disk-shaped head 837 is provided. Further, as shown in FIG. 16B, the head 837 is formed with a cross hole 838 that engages with the tip of a special tool for rotating the board replacement unit 832 .

On the other hand, as shown in FIG. 17, the game board main body 844 is formed with a base portion opening 843 composed of a main body accommodating portion 839 having a threaded portion 841 which can accommodate the main portion 836 of the base portion 833 and is screwed to the threaded portion 835 of the main portion 836, and a head portion accommodating portion 842 which can accommodate the head portion 837. Then, the board replacement unit 832 is attached to the game board body 844 by screwing the base part 833 to the game board body 844 until the head 837 is accommodated in the head accommodation part 842 and abuts against it.

In this embodiment, the front surface of the base portion 833 is configured such that the distance between the outer peripheral surface of the main body portion 836 and the nail hole 834 is less than the radius of the game ball (for example, about 5 mm). Further, when the board surface replacement unit 832 is attached to the game board main body 844, the front surface of the base part 833 is flush with the front surface of the game board main body 844, and the rear surface of the base part 833 is flush with the rear surface of the game board main body 844.

When adopting the above structure, the position of the game nail 831 can be kept the same even if the board surface replacement unit 832 is rotated, and the structure in which the board surface replacement unit 832 is screwed to the game board main body 844 enables the game nail 831 to be accurately, smoothly and reliably replaced. In particular, by applying the board surface replacement unit 832 as a game nail 831 (life nail) in the vicinity of the first starting prize winning device 33a, the game nail 831 can be pinpointed to be replaced, and waste such as replacing even the game nail 831 which does not need to be replaced can be avoided.

Further, on the front side of the game board 30, the distance between the outer peripheral surface of the main body part 836 of the base part 833 and the nail hole 834 is set to be less than the radius of the game ball, so that the game ball cannot come into contact with the boundary part between the base part 833 and the game board main body 844.例文帳に追加Therefore, the game ball moving along the front surface of the game board 30 collides with the boundary part between the base part 833 and the game board main body 844, the course of the game ball is greatly changed (repelled forward), or the base part 833 damages the game board main body 844 at the boundary part. In addition, in this embodiment, the entire front surface of the base portion 833 corresponds to the riding-on prevention area.

The configuration in which the distance between the outer peripheral edge of the front surface of the base portion 833 and the game member such as the game nail 831 is less than the radius of the game ball can be embodied in another board replacement unit 404 . For example, in the board replacement unit 811 as shown in FIG. 15, the distance between the predetermined plurality of game nails 813 and the upper side of the front surface of the base portion 812 may be less than the radius of the game ball, and the board replacement unit 811 may be provided at a position where the game ball approaches the base portion 812 from above.

(d) In the above embodiment, the game board 30, that is, the game board main body 401 and the base part 405 are made of transparent polycarbonate, but they may be made of opaque or other materials such as wood (plywood). Also, the game board main body 401 and the base portion 405 may be made of different materials. For example, the game board body 401 may be made of plywood, and the base portion 405 may be made of transparent resin. Further, the base portion 405 may be formed by mixing finely ground beads or lame sheets in the resin, or a figure or the like may be embedded in the base portion 405 . In addition, illumination means for illuminating the base portion 405 from the rear or the like (for example, capable of being relatively displaceable, capable of changing hue, color tone, and brightness) may be provided.

(e) In the above embodiment, the entire thickness direction of the positioning portion 425 of the game board main body 401 has a substantially triangular convex cross-section, and the entire thickness direction of the positioned portion 435 of the base portion 405 has a substantially triangular concave cross-sectional shape. For example, the positioning portion 425 and the positioned portion 435 having substantially triangular convex and triangular concave cross-sections may be provided only in the thickness direction central portions of the game board main body 401 and the base portion 405, and the front and rear portions of the mating surfaces of the inner peripheral surface of the base portion opening 403 and the outer peripheral surface of the base portion 405 may extend along the thickness direction of the game board 30 (in a direction perpendicular to the front surface of the game board 30). In this case, it is possible to avoid a situation in which the outer peripheral portion of the base portion 405 and the peripheral portion of the base portion opening portion 403 of the game board body 401 are sharp and easily damaged. Further, for example, the cross-sectional shape of the positioning portion 425 is not particularly limited to a triangular convex shape, and may be a substantially rectangular convex shape, a shape in which two triangles are arranged side by side, or the like. Furthermore, the positioning portion 425 may be concave and the positioned portion 435 may be convex.

In addition, in the above-described embodiment, the positioning portion 425 is provided over the entire inner peripheral surface of the base portion opening 403, and the positioned portion 435 is provided over the entire portion of the outer peripheral surface of the base portion 405 facing the positioning portion 425.

(f) Further, for example, by causing light to enter the base portion 405 of the board surface replacement unit 404 from the side (from the side of the center frame 47 with a flat end surface), a predetermined aspect may emerge at the portion where the light is incident. More specifically, the portion of the base portion 405 where the predetermined aspect is to be highlighted is bent in a direction different from that of the other portions (to form a light guide plate that does not undergo total reflection within the base portion 405 and is projected forward). Further, a light-emitting portion is provided at a portion of the center frame 47 adjacent to the base portion 405 so as to irradiate the base portion 405 with light. Such a light-emitting part is driven and controlled by the sub-control device 262 so that the lighting mode changes according to the performance or the like. As a result, only the base portion 405 of the game board 30 can derive the mode of the light guide plate.

Also, for example, a predetermined decorative member (a polarizing filter, a glitter-containing transparent string, etc.) or the front side and the rear side of the game board 30 are electrically connected to the mating surface of the game board main body 401 and the base part 405 of the board replacement unit 404 (the front side and the front side may be connected, the rear side and the rear side may be connected, or the front side or the rear side and the outer peripheral side of the game board 30 may be connected). It may be embedded so as to sandwich the wiring (which is preferably decorated) or the like. In this case, the decorative member or the like can be embedded in the game board 30 relatively easily (if the decorative member is thick, the installation recess may be formed). Furthermore, a positioning member extending between the game board main body 401 and the base part 405 may be provided on the rear side of the joint between the game board main body 401 and the base part 405 of the board replacement unit 404 (for example, a recess extending between the game board main body 401 and the base part 405 may be formed, and a positioning member that fits into the recess may be press-fitted). In this case, more accurate positioning can be performed.

(g) Further, for example, in the portion of the base portion 405 that abuts on the mounting piece 421 of the center frame 47, a recess may be formed that is recessed by the thickness of the mounting piece 421. FIG. In this case, the front surface of the attachment piece 421 can also be flush with the front surface of the game board 30 . Further, in the case of adopting such a configuration, by forming the mounting piece 421 of the center frame 47 only at a portion corresponding to the board surface replacement unit 404, for example, it is possible to avoid a situation in which the versatility of the game board body 401 is reduced by forming a recess for the mounting piece 421 in the game board body 401.

(h) In the second embodiment, the right expansion frame 444 attached to the game board main body 442 without using the board replacement unit 441 and the left-right symmetrical frame 443 attached to the game board main body 442 using two board replacement units 441 are exchangeable. For example, the center frame 47 attached to the game board body 442 using one board replacement unit 441 and the center frame 47 attached to the game board body 442 using two board replacement units 441 may be replaceable.

(i) You may implement as a pachinko machine of a different type from the said embodiment. For example, variable ball entry means comprising a specific area into which a game ball moving in the game area can enter, a movable means (feather member) that can change between an open state that allows a ball to enter the specific area and a closed state that prohibits entry into the specific area, specific ball entry means and non-specific ball entry means that allow a game ball that has entered the specific area to enter, specific ball entry detection means (condition fulfillment detection means) that detects a game ball that has entered the specific ball entry means, and provided outside the specific area, A start ball entry means for allowing a game ball moving in the game area to enter, a start ball entry detection means for detecting the game ball entering the start ball entry means, and a main control means for controlling the opening and closing of the variable ball entry means, wherein when the game ball enters the specific area, regardless of whether the game ball enters the specific ball entry means or the non-specific ball entry means, a predetermined number of game values (game balls) are awarded to the player, and the main control means is based on the detection of the start ball entry detection means. Then, a small winning state in which the variable ball entering means is opened once or a plurality of times for a first period of time, or until the variable ball entering means is kept open for a second period of time longer than the first time, or until a specified number of game balls enter the open variable ball entering means is regarded as one round. , and may be applied to a game machine in which a jackpot state is generated when the specific ball-entering detection means detects the detection. In addition, other than the pachinko machine, it may be implemented as an arrangement ball machine, various game machines such as majang ball similar thereto.

[Appendix]
Technical ideas that can be grasped from the above embodiment will be described below.
2. Description of the Related Art Conventionally, pachinko machines and the like are known as one type of gaming machines. A pachinko machine is provided with a game board, and in front thereof, a game area is formed in which game balls shot by a shooting device are guided. In addition, on the front side of the game board, there are provided various game members such as game nails for diversifying the behavior of game balls moving in the game area and winning devices that allow game balls moving in the game area to enter.
By the way, it is desired to appropriately install the game members arranged in the game area.
SUMMARY OF THE INVENTION The present invention has been made to solve the problems exemplified above, and its object is to provide a game machine in which game members arranged in a game area can be preferably installed.
The gaming machine of the present invention is
A launching means (shooting device 60) for shooting game balls;
a game area where game balls shot by the shooting means are guided (an area between the game board 30 and the glass unit 137 and defined by the rail 50 and the inner peripheral surface of the window hole 39 of the resin base 38);
A plurality of game members capable of changing the movement path of the game ball moving in the game area (general winning port 31, variable winning device 32, first starting winning device 33a, second starting winning device 33b, through gate 34, variable display device unit 35, game nails, various members such as windmills),
In a gaming machine comprising a rear defining portion (game board main body 401, particularly the front surface) that defines the rear portion of the game area,
A game member unit (board replacement unit 404) comprising a predetermined game member and a base portion (base portion 405) to which the predetermined game member is attached,
The game member unit is inserted into a unit opening (board base portion opening 403) formed in the rear defining portion so that a portion of the base portion defines a portion of the rear portion of the game area.
A specific game member (through hole 402) that is arranged to pass through an opening formed in the rear defining portion and is attached to the rear defining portion using a mounting member,
The unit opening is provided so as to expand the opening in which the specific game member is arranged,
The game member unit is configured to be installed adjacent to the specific game member,
The front surface of the base portion has a portion extending parallel to the front surface of the rear defining portion.
According to the present invention, it is possible to suitably install the game members arranged in the game area.

A. 2. Description of the Related Art Conventionally, pachinko machines and the like are known as one type of gaming machines. A pachinko machine is provided with a game board, and in front thereof, a game area is formed in which game balls shot by a shooting device are guided. In addition, on the front side of the game board, various game members such as a game nail for diversifying the behavior of the game ball moving in the game area and a prize-winning device that allows the game ball moving in the game area to enter are provided (see, for example, Japanese Unexamined Patent Application Publication No. 2003-154110).

In addition, the game members arranged in the game area are subjected to loads such as repeated collisions of the game balls, so that the game members may be damaged. For example, a game nail may break due to deformation due to collision with a game ball, adjustment to return to the original state after being bent due to collision, or deterioration (abrasion, etc.) due to long-term use. In this case, it is necessary to replace the game member.

By the way, when attaching a new game member to a place where the game member has been removed, there is a concern that the game member may not be properly attached. That is, for example, even if a new game nail is attached to a nail hole from which a game nail as a game member has been pulled out, the nail hole has become loose and cannot be attached well, or even if the nail hole is stuffed and a game nail is driven into the hole, the game nail may be moved in a predetermined direction and slightly displaced from the original arrangement of the game nail. Further, for example, when a winning device as a game member is attached to a game board with screws, even if an attempt is made to attach a new winning device with screws, the screw holes may become loose and may not be attached successfully, or even if the screw holes are stuffed and screws are screwed into the screw holes, the screw may be pulled in a predetermined direction and slightly displaced from the original arrangement of the screws.

The present invention has been made to solve the problems exemplified above, and its object is to provide a game machine capable of improving the accuracy and workability of exchanging game members arranged in the game area.

Means A-1. a launching means for launching a game ball;
a game area provided on the front side of the game board, in which the game balls shot by the shooting means are guided;
A game machine comprising a plurality of game members protruding forward from the game board and capable of changing the movement path of a game ball moving in the game area,
A board replacement unit comprising a predetermined game member and a base portion to which the game member is attached,
The gaming machine is characterized in that the base portion is installed in a state of being inserted into an opening for the base portion (penetrating in the front-rear direction) formed in the game board so as to constitute a part of the game board.

According to means A-1, the base part of the board replacement unit serves as a connection between the game member of the board replacement unit and the main body of the game board (game board main body), and when the game member of the board replacement unit is replaced, the entire base part (part of the game board) is replaced. Further, the shape of the base portion is less restricted than that of the game member, and the shape of the attachment portion to the game board main body can be designed relatively freely. Therefore, the game member of the board surface replacement unit can be easily removed from the game board (game board main body) compared to, for example, a game member directly attached to the game board (game board main body) while sufficiently securing the stability in the mounting state to the game board main body. Therefore, it is possible to avoid such a situation that when the game member is damaged and the game member is removed from the game board, the part where the game member was attached is damaged on the game board, and even if a new game member is to be attached to the corresponding part, it cannot be preferably attached (the position of the game member is displaced, etc.), or the design is deteriorated due to the scar left. As a result, the game member can be exchanged accurately and relatively easily, and the accuracy and workability of the exchange of the game member can be improved.

In addition, it becomes possible to relatively easily change the design of the game board at the base. For example, it is possible to increase the variations and functions of the game board relatively easily, such as by making the color or the like different from that of the game board main body for a predetermined purpose such as marking the target position of the game ball (to draw attention to the main part) or making the game ball easier to see, or by integrally forming a part on the rear side of the base part where a predetermined member can be attached, locked, and supported. Therefore, it is possible to improve functionality and design. Also, when changing the model, for example, by replacing the board surface replacement unit, it is possible to relatively easily change the arrangement of game members such as game nails and prize winning openings, and change information means such as model information.

Means A-2. The gaming machine according to means A-1, wherein the rear surface of the base portion is flush with the rear surface of the game board or located forward of the rear surface of the game board.

According to the means A-2, it is possible to avoid a situation in which, for example, the base part protrudes rearward from the rear surface of the game board, thereby hindering the arrangement of various members (various control devices, etc.) provided on the rear surface side of the game board by the board surface replacement unit. In other words, the arrangement of various members provided on the rear surface side of the game board can reduce the situation that the part where the board replacement unit can be installed is limited, and the board replacement unit can be installed at a desired position (due to the arrangement of the various game members on the game area side).

Means A-3. A gaming machine according to means A-1 or A-2, wherein a portion of the base portion including at least the upper side portion of the front surface is flush with the front surface of the game board or positioned behind the front surface of the game board.

According to the means A-3, the part including the upper side part of the front face of the base part and the front face of the game board are flush with each other or positioned behind the front face of the game board, so that it is possible to prevent a situation in which a game ball flowing down from above the game member of the board replacement unit along the front face of the game board collides with the upper surface of the base part. Therefore, it is possible to avoid problems caused by the game ball colliding with the upper surface of the base part and being bounced forward (for example, collision with the glass unit in front of the game area to generate noise, or deviation from the winning means due to a large change in the movement path of the game ball, etc.). As a result, the movement of the game ball in the peripheral portion of the game member can be made smoother, and the game can be progressed comfortably.

Furthermore, it is possible to avoid the situation that the base part is damaged or the installation state of the base part is adversely affected (the base part and the game member are tilted, etc.) due to the collision of the game ball with the upper surface of the base part. In addition, the formation of a step between the base part and the game board main body can prevent a situation in which the impression of a game machine or a game machine maker is deteriorated (whether it is a poor product or not, etc.) and the design is deteriorated.

The "upper side of the front surface of the base" is intended to be the front side of the surface that is visible when the base is viewed from above, and the "part including the upper side of the front surface of the base" preferably includes the entire front side, but may be part of the front side, and can be appropriately designed according to the shape of the base and the necessity (such as whether the path is likely to pass through a game ball).

Means A-4. a specific game member disposed so as to pass through an opening formed in the game board and attached to the game board using a mounting member;
The opening for the base portion is formed so as to expand the opening for the specific game member,
The board replacement unit is provided adjacent to the specific game member,
The base portion is
an attachment portion attached to the specific game member using an attachment member;
A game machine according to any one of means A-1 to A-3, further comprising a positioned portion that is positioned in the front-rear direction by coming into contact with a positioning portion formed on the inner peripheral surface of the opening for the base portion of the game board.

According to means A-4, since positioning is performed by the positioned portion of the base portion and the positioning portion of the game board body, the number and installation locations of the mounting members used for mounting the board replacement unit to the game board body and the specific game member can be reduced, and in particular, the mounting member for connecting the board replacement unit and the game board body can be eliminated. Therefore, it is possible to improve the workability of attaching and detaching the board surface replacement unit, and to suppress deterioration of the design property due to the mounting member being visible.

Means A-5. One of the positioning portion and the positioned portion has a convex portion with a substantially triangular cross-section, and the other has a concave portion with a substantially triangular cross-section that fits into the convex portion. The game machine according to means A-4.

According to the means A-5, relative displacement forward and backward can be prevented more reliably. Also, for example, compared to the case where one of the positioning part and the positioned part has a substantially rectangular cross section, it is possible to suppress the situation in which the positioning part and the positioned part are damaged (broken) when force is applied in the front-rear direction (shear stress acts on the positioning part) to the base part of the board replacement unit or the part of the game board main body adjacent to the base part. Also, when the positioning part and the positioned part are butted against each other, one of the positioning part and the positioned part is guided by the slope of the other and relatively displaced to an appropriate position even if the positions in the front-rear direction are not completely matched. Therefore, it is possible to improve the mounting workability of the board replacement unit.

Means A-6. The positioning portion is formed over the entire inner peripheral surface of the opening for the base portion, and the portion to be positioned is positioned in contact with the entire circumference of the positioning portion. A gaming machine according to means A-4 or A-5.

According to the means A-6, the positioning between the base portion and the game board main body can be performed more firmly. Further, for example, if part of the outer peripheral surface of the base portion facing the inner peripheral surface of the base portion opening of the game machine main body is a surface extending in a direction perpendicular to the front surface of the game board (thickness direction of the game board) (in the case where it is not a portion to be positioned), there is a concern that a gap will be formed at the boundary portion (joint portion) between the surface and the game machine main body so that the rear of the game board can be seen. In this regard, by using the entire inner circumference of the opening for the base portion of the game board body as the positioning portion and positioning with the positioned portion over the entire inner circumference, the positioning portion and the positioned portion overlap in the front and back direction over the entire inner circumference. Therefore, such concerns can be dispelled.

Furthermore, as in means A-5, when the positioning part and the positioned part are used to perform forward and rearward positioning, the base part cannot be attached to the base part opening of the game board body by displacing it in the front-rear direction. However, since the opening part for the specific game member is formed adjacent to the base part opening part as in means A-4, it is possible to insert the base part from the opening part for the specific game member into the base part opening part.

Means A-7. The mounting member for mounting the board replacement unit to the specific game member is a screw having a head,
The game machine according to any one of means A-4 to A-6, wherein the screw passes through the specific game member from the side of the specific game member and is screwed to the base portion of the board replacement unit.

According to means A-7, the board changing unit and the specific game member are connected by a screw having a head, and the screw is screwed into the base of the board changing unit via the specific game member. Therefore, when the game member of the board replacement unit is replaced, the screw is screwed into the base portion of the new board replacement unit. For example, it is possible to avoid the possibility that the screw hole of the specific game member is loose and the screw cannot be properly screwed, as in the case of adopting a configuration in which the screw penetrates the base portion from the base portion side and is screwed to the specific game member.

Means A-8. a first use state in which the first specific game member is attached corresponding to the opening formed in the game board;
The game machine according to any one of means A-4 to A-7, wherein a second use state in which a second specific game member having a smaller area than the first specific game member corresponding to the opening and the board surface replacement unit provided so as to fill a gap formed between the inner peripheral surface of the opening and the second specific game member are installed can be selected.

According to the means A-8, it is possible to standardize the game board main body, thereby reducing the cost of the game board main body and improving the convenience of management.

In addition, "a first use state in which a first specific game member corresponding to the opening formed in the game board, and a first board surface replacement unit provided so as to fill the gap formed between the inner peripheral surface of the opening and the first specific game member are attached, and a second specific game member corresponding to the opening, having a smaller area than the first specific game member, and a second specific game member provided to fill the gap formed between the inner peripheral surface of the opening and the second specific game member. It may be configured to be capable of selecting a second use state in which two board replacement units are attached. Further, a predetermined gap formed between the inner peripheral surface of the opening and the specific game member may be filled with the base portion of one board replacement unit, or may be filled with the base portions of a plurality of board replacement units.

Means A-9. A member-side mounting hole is formed in the first specific game member for mounting the first specific game member to the game board using the mounting member,
The game machine according to means A-8, wherein a hole used as a nail hole for attaching the game nail in the second state of use is used as a board side mounting hole for mounting the mounting member through the member side mounting hole in the first state of use.

According to the means A-9, it is possible to avoid a situation in which a separate board-side mounting hole is required for mounting the first specific game member to the game board main body in the first use state (a board-side mounting hole is purposely opened in the first use state). In addition, it is possible to avoid a situation in which the board-side mounting holes in the first use state are not used in the second use state (unused holes exist and are visually recognized), causing a sense of incongruity, etc., or deteriorating the design.

Means A-10. The game machine according to any one of means A-1 to A-9, wherein the game member of the board replacement unit is a game nail projecting forward from the front surface of the game board.

When the game nail protruding from the game board is broken at the root part, the game nail left inside the game board is pushed out from the game board using a jig and taken out. Thus, in the work of removing the rest of the broken game nail from the game board or the work of installing a new game nail in place of the broken game nail, actions such as hitting the new game nail with a hammer or the like are carried out, such as a jig brought into contact with the buried game nail. For this reason, if the game board is left attached to the game machine or various members are left attached to the game board during such work, there is a concern that each part may be greatly affected (for example, the impact may break the electrically operated member, or the mounting state of the various members may be released, etc.). Therefore, when replacing the game nail, basically the game board is removed from the game machine and various members are removed from the game board. For this reason, it takes a lot of labor and time to replace the game nails, and the risk of work mistakes increases, and there is concern that the game board and game members may be damaged (by mishandling the hammer), or the game board and members on the back side may be dropped and damaged.

In this respect, by adopting the configuration of the above-mentioned means A-1, which includes a board replacement unit in which the game member is attached to the base portion constituting a part of the game board, it is possible to dispense with the work of hitting the game nail or the like with a hammer when replacing the game nail. Therefore, even if the game board is attached to the main body of the game machine, the game member can be replaced, and the occurrence of work mistakes is suppressed, and even if it should occur, the game board or the game member can be prevented from being damaged (for example, by hitting the front surface of the game board or the game member with a hammer to damage them). As a result, it is possible to improve the workability when replacing the game nails, and reduce the risk of damage to the game board, game members, and the like.

Means A-11. The gaming machine according to any one of means A-1 to A-10, wherein the gaming board and the base portion of the board replacement unit are made of a transparent resin material.

In a configuration in which the game board is transparent and the inside and the like of the game board are visible through the game board as in the means A-11, for example, if the rear surface or the inside of the game board is damaged when the game member is removed from the game board, there is a concern that the damaged part will be visible and the design will be deteriorated. In this regard, as in the above means A-1, with respect to the game members of the board replacement unit, the base part to which the game members are attached is replaced, and the whole board replacement unit can be removed relatively smoothly from the game board main body. Therefore, it is possible to avoid a situation in which a scar or the like formed when a game member is replaced is visually recognized, resulting in deterioration of the design.

Further, as in the above means A-1, the rear surface of the base portion of the board surface replacement unit is flush with the rear surface of the game board (main body) or located in front of it, thereby facilitating the installation of various decorative members visible through the game board on the rear surface side of the game board. For example, the cel image pasted on the rear surface of the game board main body and the cel image pasted on the rear surface of the base part can be flush with each other, or a decorative accessory can be installed in the space behind the base part. Therefore, the space on the rear side of the game board can be used more effectively.

Further, according to the means A-4, since it is not necessary to use a mounting member for connecting the base portion of the board replacement unit and the game board main body, it is possible to prevent a situation in which the entire mounting member (including all the parts embedded in the game board) is visually recognized through the transparent game board, thereby degrading the design. In addition, ``the specific game member has an attachment piece connected by the attachment member to the attachment portion of the base portion, and the attachment piece is made of an opaque material and is positioned in front of the attachment portion''. In this case, since the mounting member is provided on the opaque mounting piece, the mounting member is less conspicuous. In addition, since the mounting piece of the specific game member is positioned in front of the base portion and the mounting member is mounted from the front, the mounting member can be mounted while holding the game member by hand (so as not to fall or shift its position) (for example, compared to the case where the mounting piece is positioned behind the base portion and the mounting member is mounted from the rear).

Furthermore, in response to measure A-10, a game board made of a resin material is harder than a conventional game board made of plywood, and there is concern that the game nails may easily break due to this. In addition, the game board has a strong force for holding the game nail, and the task of removing the game nail (broken off inside the game board) from the game board becomes difficult, and there is a fear that the game board may be damaged. In this respect, as in the above means A-1, by providing a board replacement unit so that the game nails can be replaced accurately and relatively easily, even if the chances of replacing the game nails increase, sufficient maintenance can be performed.

Means A-12. A game machine according to any one of means A-1 to A-11, wherein the base portion has a run-on prevention area in which the distance between the outer peripheral edge of the front surface of the base portion and the game member is less than the radius of the game ball.

According to means A-12, it is possible to avoid a situation in which a game ball moving along the game board surface comes into contact with the boundary between the outer periphery of the base and the game board main body with respect to the run-on prevention area. Therefore, for example, when a step, gap, etc. is formed (unintentionally due to manufacturing error or long-term use) at the boundary between the outer periphery of the base and the game board main body, it is possible to avoid a situation in which the movement path of the game ball is significantly (irregularly) changed at the boundary.

B. 2. Description of the Related Art Conventionally, pachinko machines and the like are known as one type of gaming machines. A pachinko machine is provided with a game board, and in front thereof, a game area is formed in which game balls shot by a shooting device are guided. In addition, on the front side of the game board, there are provided various game members such as game nails that diversify the behavior of game balls moving in the game area, and winning devices that allow game balls moving in the game area to enter (see, for example, Japanese Unexamined Patent Application Publication No. 2003-154110).

By the way, when replacing a damaged game member, when the game member is removed from the game board, there is a concern that the part where the game member was attached may be damaged, making it impossible to suitably attach a new game member.

In addition, when screws for attaching the winning device to the game board and screws for fixing between parts when the winning device is composed of a plurality of parts are frequently used, there is a concern that the design may be deteriorated. Especially when the game board is made of a transparent material, such concerns become more pronounced.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems exemplified above, and its object is to provide a game machine capable of improving the design while improving the accuracy and workability of exchanging game members.

Means B-1. a launching means for launching a game ball;
a game area provided on the front side of the game board, in which the game balls shot by the shooting means are guided;
a plurality of game members projecting forward from the game board and capable of changing the movement path of the game ball moving in the game area;
A board replacement unit comprising a predetermined game member and a base portion to which the game member is attached,
The base portion is installed in a state of being inserted into a base portion opening (passing through in the front-rear direction) formed in the game board so as to constitute a part of the game board,
a specific game member disposed so as to pass through an opening formed in the game board and attached to the game board using a mounting member;
The opening for the base portion is formed so as to expand the opening for the specific game member,
The board replacement unit is provided adjacent to the specific game member,
The base portion is
an attachment portion attached to the specific game member using an attachment member;
A gaming machine, comprising: a positioned portion that is positioned in the front-rear direction by contacting a positioning portion formed on an inner peripheral surface of the opening for the base portion of the game board.

According to the means B-1, the base part of the board replacement unit serves as a connection between the game member of the board replacement unit and the main body of the game board (game board main body), and when the game member of the board replacement unit is replaced, the entire base part (part of the game board) is replaced. Further, the shape of the base portion is less restricted than that of the game member, and the shape of the attachment portion to the game board main body can be designed relatively freely. Therefore, the game member of the board surface replacement unit can be easily removed from the game board (game board main body) compared to, for example, a game member directly attached to the game board (game board main body) while sufficiently securing the stability in the mounting state to the game board main body. Therefore, it is possible to avoid such a situation that when the game member is damaged and the game member is removed from the game board, the part where the game member was attached is damaged on the game board, and even if a new game member is to be attached to the corresponding part, it cannot be preferably attached (the position of the game member is displaced, etc.), or the design is deteriorated due to the scar left. As a result, the game member can be exchanged accurately and relatively easily, and the accuracy and workability of the exchange of the game member can be improved.

In addition, since positioning is performed by the positioned portion of the base portion and the positioning portion of the game board (game board main body), the number and installation locations of the mounting members used for mounting the board replacement unit to the game board main body and the specific game member can be reduced, and in particular, the mounting member for connecting the board replacement unit and the game board main body can be eliminated. Therefore, it is possible to improve the workability of attaching and detaching the board surface replacement unit, and to suppress deterioration of the design property due to the mounting member being visible.

In addition, it becomes possible to relatively easily change the design of the game board at the base. For example, it is possible to increase the variations and functions of the game board relatively easily, such as by making the color or the like different from that of the game board main body for a predetermined purpose such as marking the target position of the game ball (to draw attention to the main part) or making the game ball easier to see, or by integrally forming a part on the rear side of the base part where a predetermined member can be attached, locked, and supported. Therefore, it is possible to improve functionality and design. Also, when changing the model, for example, by replacing the board surface replacement unit, it is possible to relatively easily change the arrangement of game members such as game nails and prize winning openings, and change information means such as model information.

Means B-2. One of the positioning portion and the positioned portion has a convex portion with a substantially triangular cross section, and the other has a concave portion with a substantially triangular cross section that fits into the convex portion. The gaming machine according to means B-1.

According to the means B-2, relative displacement forward and backward can be prevented more reliably. Also, for example, compared to the case where one of the positioning part and the positioned part has a substantially rectangular cross section, it is possible to suppress the situation in which the positioning part and the positioned part are damaged (broken) when force is applied in the front-rear direction (shear stress acts on the positioning part) to the base part of the board replacement unit or the part of the game board main body adjacent to the base part. Also, when the positioning part and the positioned part are butted against each other, one of the positioning part and the positioned part is guided by the slope of the other and relatively displaced to an appropriate position even if the positions in the front-rear direction are not completely matched. Therefore, it is possible to improve the mounting workability of the board replacement unit.

Means B-3. The positioning portion is formed over the entire inner peripheral surface of the opening for the base portion, and the portion to be positioned is positioned by contacting the entire circumference of the positioning portion. The gaming machine according to means B-1 or B-2.

According to the means B-3, the positioning between the base portion and the game board main body can be performed more firmly. Further, for example, if part of the outer peripheral surface of the base portion facing the inner peripheral surface of the base portion opening of the game machine main body is a surface extending in a direction perpendicular to the front surface of the game board (thickness direction of the game board) (in the case where it is not a portion to be positioned), there is a concern that a gap will be formed at the boundary portion (joint portion) between the surface and the game machine main body so that the rear of the game board can be seen. In this regard, by using the entire inner circumference of the opening for the base portion of the game board body as the positioning portion and positioning with the positioned portion over the entire inner circumference, the positioning portion and the positioned portion overlap in the front and back direction over the entire inner circumference. Therefore, such concerns can be dispelled.

Furthermore, as in means B-2, when the positioning part and the positioned part are used to perform forward and rearward positioning, the base part cannot be attached to the base part opening of the game board body by displacing it in the front-back direction. However, as in the means B-1, since the specific game member opening is formed adjacent to the base part opening, it is possible to insert the base part from the specific game member opening into the base part opening.

Means B-4. The mounting member for mounting the board replacement unit to the specific game member is a screw having a head,
The game machine according to any one of means B-1 to B-3, wherein the screw passes through the specific game member from the side of the specific game member and is screwed to the base portion of the board replacement unit.

According to means B-4, the board changing unit and the specific game member are connected by a screw having a head, and the screw is screwed to the base of the board changing unit via the specific game member. Therefore, when the game member of the board replacement unit is replaced, the screw is screwed into the base portion of the new board replacement unit. For example, it is possible to avoid the possibility that the screw hole of the specific game member is loose and the screw cannot be properly screwed, as in the case of adopting a configuration in which the screw penetrates the base portion from the base portion side and is screwed to the specific game member.

Means B-5. a first use state in which the first specific game member is attached corresponding to the opening formed in the game board;
The game machine according to any one of means B-1 to B-4, wherein a second use state in which a second specific game member having a smaller area than the first specific game member corresponding to the opening and the board surface replacement unit provided so as to fill a gap formed between the inner peripheral surface of the opening and the second specific game member are installed can be selected.

According to the means B-5, the game board main body can be standardized, and the cost of the game board main body can be reduced and the convenience of management can be improved.

In addition, "a first use state in which a first specific game member corresponding to the opening formed in the game board, and a first board surface replacement unit provided so as to fill the gap formed between the inner peripheral surface of the opening and the first specific game member are attached, and a second specific game member corresponding to the opening, having a smaller area than the first specific game member, and a second specific game member provided to fill the gap formed between the inner peripheral surface of the opening and the second specific game member. It may be configured to be capable of selecting a second use state in which two board replacement units are attached. Further, a predetermined gap formed between the inner peripheral surface of the opening and the specific game member may be filled with the base portion of one board replacement unit, or may be filled with the base portions of a plurality of board replacement units.

Means B-6. A member-side mounting hole is formed in the first specific game member for mounting the first specific game member to the game board using the mounting member,
The game machine according to means B-5, wherein a hole used as a nail hole for attaching the game nail in the second state of use is used as a board side mounting hole for mounting the mounting member through the member side mounting hole in the first state of use.

According to the means B-6, it is possible to avoid a situation in which a separate board-side mounting hole is required for mounting the first specific game member to the game board main body in the first use state (a board-side mounting hole is purposely opened in the first use state). In addition, it is possible to avoid a situation in which the board-side mounting holes in the first use state are not used in the second use state (unused holes exist and are visually recognized), causing a sense of incongruity, etc., or deteriorating the design.

Means B-7. The game machine according to any one of means B-1 to B-6, wherein the game member of the board replacement unit is a game nail projecting forward from the front surface of the game board.

When the game nail protruding from the game board is broken at the root part, the game nail left inside the game board is pushed out from the game board using a jig and taken out. Thus, in the work of removing the rest of the broken game nail from the game board or the work of installing a new game nail in place of the broken game nail, actions such as hitting the new game nail with a hammer or the like are carried out, such as a jig brought into contact with the buried game nail. For this reason, if the game board is left attached to the game machine or various members are left attached to the game board during such work, there is a concern that each part may be greatly affected (for example, the impact may break the electrically operated member, or the mounting state of the various members may be released, etc.). Therefore, when replacing the game nail, basically the game board is removed from the game machine and various members are removed from the game board. For this reason, it takes a lot of labor and time to replace the game nails, and the risk of work mistakes increases, and there is concern that the game board and game members may be damaged (by mishandling the hammer), or the game board and members on the back side may be dropped and damaged.

In this respect, by adopting the configuration of the above-mentioned means B-1, which includes a board replacement unit in which the game member is attached to the base part constituting a part of the game board, it is possible to dispense with the work of hitting the game nail or the like with a hammer when replacing the game nail. Therefore, even if the game board is attached to the main body of the game machine, the game member can be replaced, and the occurrence of work mistakes is suppressed, and even if it should occur, the game board or the game member can be prevented from being damaged (for example, by hitting the front surface of the game board or the game member with a hammer to damage them). As a result, it is possible to improve the workability when replacing the game nails, and reduce the risk of damage to the game board, game members, and the like.

Means B-8. The gaming machine according to any one of means B-1 to B-7, wherein the gaming board and the base portion of the board replacement unit are made of a transparent resin material.

In a configuration where the game board is transparent and the inside and the like of the game board can be seen through the game board as in the means B-8, for example, when the game member is removed from the game board, if the rear face or the inside of the game board is damaged, the damaged part will be visible, and there is a concern that the design will be deteriorated. In this respect, as in the above means B-1, the base part on which the game member is attached is replaced with respect to the game member of the board replacement unit, and the whole board replacement unit can be relatively smoothly removed from the game board main body. Therefore, it is possible to avoid a situation in which a scar or the like formed when a game member is replaced is visually recognized, resulting in deterioration of the design.

Further, according to the means B-1, it is not necessary to use a mounting member to connect the base portion of the board surface replacement unit and the game board main body, so it is possible to prevent a situation in which the entire mounting member (including all the parts embedded in the game board) is visually recognized through the transparent game board, thereby degrading the design. In addition, ``the specific game member has an attachment piece connected by the attachment member to the attachment portion of the base portion, and the attachment piece is made of an opaque material and is positioned in front of the attachment portion''. In this case, since the mounting member is provided on the opaque mounting piece, the mounting member is less conspicuous. In addition, since the mounting piece of the specific game member is positioned in front of the base portion and the mounting member is mounted from the front side, the mounting member can be mounted while holding the game member by hand (so as not to fall or shift position), and workability is improved (for example, compared to the case where the mounting piece is positioned behind the base portion and the mounting member is mounted from the rear).

Furthermore, in response to measure B-6, the game board made of resin material is harder than the conventional game board made of plywood, and there is concern that the game nails may easily break due to this. In addition, the game board has a strong force for holding the game nail, and the task of removing the game nail (broken off inside the game board) from the game board becomes difficult, and there is a fear that the game board may be damaged. In this regard, as in the above means B-1, by providing a board surface replacement unit so that the game nails can be replaced accurately and relatively easily, it is possible to perform sufficient maintenance even if the chances of replacing the game nails increase.

Means B-9. The base portion is characterized in that the distance between the outer peripheral edge of the front surface of the base portion and the game member is provided with a run-on prevention area in which the distance is less than the radius of the game ball. The gaming machine according to any one of means B-1 to B-8.

According to means B-9, it is possible to avoid a situation in which a game ball moving along the game board surface comes into contact with the boundary between the outer periphery of the base and the game board main body in the run-on prevention area. Therefore, for example, when a step, gap, etc. is formed (unintentionally due to manufacturing error or long-term use) at the boundary between the outer periphery of the base and the game board main body, it is possible to avoid a situation in which the movement path of the game ball is significantly (irregularly) changed at the boundary.

Means B-10. The game machine according to any one of means B-1 to B-9, wherein the rear surface of the base portion is flush with the rear surface of the game board or located forward of the rear surface of the game board.

According to the means B-10, for example, the base portion projects backward from the rear surface of the game board, thereby preventing the arrangement of various members (various control devices, etc.) provided on the rear surface side of the game board by the board surface replacement unit. In other words, the arrangement of various members provided on the rear surface side of the game board can reduce the situation that the part where the board replacement unit can be installed is limited, and the board replacement unit can be installed at a desired position (due to the arrangement of the various game members on the game area side).

Further, in the configuration in which the game board is transparent and the inside and the like of the game board are visible through the game board as in the above means B-8, the rear surface of the base portion of the board replacement unit is flush with the rear surface of the game board (main body) or is positioned in front thereof, thereby facilitating the installation of various decorative members visible through the game board on the rear side of the game board. For example, the cel image pasted on the rear surface of the game board main body and the cel image pasted on the rear surface of the base part can be flush with each other, or a decorative accessory can be installed in the space behind the base part. Therefore, the space on the rear side of the game board can be used more effectively.

Means B-11. A gaming machine according to any one of means B-1 to B-10, wherein a portion of the base portion including at least the upper side portion of the front surface is flush with the front surface of the game board or positioned behind the front surface of the game board.

According to the means B-11, since the part including the upper side part of the front face of the base part and the front face of the game board are flush with each other or positioned behind the front face of the game board, it is possible to prevent the game balls flowing down along the front face of the game board from above the game members of the board replacement unit from colliding with the upper face of the base part. Therefore, it is possible to avoid problems caused by the game ball colliding with the upper surface of the base part and being bounced forward (for example, collision with the glass unit in front of the game area to generate noise, or deviation from the winning means due to a large change in the movement path of the game ball, etc.). As a result, the movement of the game ball in the peripheral portion of the game member can be made smoother, and the game can be progressed comfortably.

Furthermore, it is possible to avoid situations in which the base part is damaged or the attachment state of the base part is adversely affected due to the collision of the game ball with the upper surface of the base part. In addition, the formation of a step between the base part and the game board main body can prevent a situation in which the impression of a game machine or a game machine maker is deteriorated (whether it is a poor product or not, etc.) and the design is deteriorated.

The "upper side of the front surface of the base" is intended to be the front side of the surface that is visible when the base is viewed from above, and the "part including the upper side of the front surface of the base" preferably includes the entire front side, but may be part of the front side, and can be appropriately designed according to the shape of the base and the necessity (such as whether the path is likely to pass through a game ball).
