The game ball guided on the stage 153 falls from the stage 153 to the front game area, or rolls on the stage 153 and then enters the pocket 154 formed at the center back side of the stage 153. . In addition, the pocket 154 communicates with a guide passage 155 that leads to a game area directly above the first start winning device 33a, and a game ball that has entered the pocket 154 will be described later with a relatively high probability. The first start winning device 33a is entered.

  A first start winning device 33a is disposed below the variable display device unit 35. The first start winning device 33a protrudes forward from the front portion of the game board 30, and a winning opening (start winning port) through which a game ball can always win is opened. Note that the first start winning device 33a of the present embodiment is not provided with an opening / closing member that changes the ease of entering a game ball into the first start winning device 33a.

  A second start winning device 33b is disposed below the first start winning device 33a. The second start winning device 33b can be rotated and displaced between the open position and the closed position adjacent to the left and right sides of the pay opening (start winning port) of the second start winning device 33b where a game ball can enter. A pair of blade members 37 are provided. 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 It is in a closed state where it is impossible to enter the ball. On the other hand, by changing the blade member 37 to the open position that opens outward, the second start winning device 33b secures a gap through which the game ball passes between the blade member 37 and the first start winning device 33a. The ball is allowed to enter, and the game ball moving to the side of the second start winning device 33b by the blade member 37 is in the open state guided to the start winning port of the second start winning device 33b.

  As will be described in detail later, the first start winning device 33a and the second starting winning device 33b include a first start winning switch 224a and a second starting winning switch as condition establishment detecting means for detecting a winning game ball, respectively. 224b is provided, and when a game ball is detected by the start winning switches 224a and 224b, whether or not to generate a big hit state or the like is determined, and a special display device 43a, which will be described later, 43b and the decorative symbol display device 42 are configured to perform variable display. And when winning in the winning / losing lottery, a jackpot state is given as a special gaming state in which the variable winning device 32 is opened.

  A through gate 34 is arranged in an area located on the left side of the variable display device unit 35 (left side area) and an area located on the right side of the variable display device unit 35 (right side area) in the game area. ing. The through gate 34 is configured such that game balls flowing down the game area can pass one by one. As will be described in detail later, the through gate 34 includes a through gate switch 225 that can detect a game ball passing through the through gate 34.

The apparatus 41 performs a variable display for teaching the result of the entry support lottery. If the winning support lottery is won, the second start winning device 33b is opened for a specified time after the end of the variation display.

  In the present embodiment, there are a “low probability state” in which the jackpot is won with a predetermined probability in the winning lottery and a “high probability state” in which the jackpot is won with a higher probability than the low probability state in the winning lottery. Furthermore, the opening / closing member 37 of the second start winning device 33b is opened relatively frequently, and the opening / closing member 37 is almost opened, in a “highly-entered state” that makes it easier for the game ball to enter the second start winning device 33c. There is a “low pitch state” in which it is difficult for the game ball to enter the second start winning device 33b. Hereinafter, the low probability state and the low entry state are referred to as “normal mode”, and the low probability state and the high entry state are referred to as “time reduction mode”. A certain state is referred to as a “probability change mode”.

  Note that the high pitched state includes, for example, (1) a state in which the fluctuation display time in the normal symbol display device 41 is shorter than that in the low pitched state, and (2) one opening time of the second start winning device 33b ( A state in which the specified time) is longer than that in the low entry state, and (3) a state in which the prescribed number of game balls that can be entered per one opening of the second start winning device 33b is larger than in the low entry state, (4) A state in which the number of times the second start winning device 33b is released per winning of the winning support lottery is larger than that in the low entering state, (5) the winning probability of the winning support lottery is lower than in the low entering state. And so on. The high pitched-in state in the present embodiment adopts the configurations (1), (2), and (5). Of course, not limited to this, any one of the configurations (1) to (5) or any combination of these configurations (1) to (5) may be adopted as the “highly-entered state”. . As a result, it becomes easier for the game balls to win the second start winning device 33b frequently, and the number of times that the winning lottery is executed is increased, and a decrease in the number of balls held by the player is suppressed. .

  Furthermore, in the present embodiment, the normal mode and the probability variation mode are continued until the jackpot state is generated, while the time reduction mode is the special display devices 43a and 43b and the decorative symbol display device 42 even if the jackpot state does not occur. When the fluctuation display in is performed 100 times, the display is terminated and the mode is shifted to the normal mode.

  Further, the jackpot type of the present embodiment is of three types: 15 round probability variation jackpot (hereinafter referred to as “15RS”) and 16 round normal jackpot (hereinafter referred to as “15RN”). Then, when the variable winning device 32 is opened for 30 seconds or when eight game balls enter the variable winning device 32 after the variable winning device 32 is opened, it is repeated 15 times. After that, the jackpot state ends. In addition, “probability change mode” is given after the big hit state of “15RS”, and “time reduction mode” is given after the big hit state of “15RN”.

  A variable winning device 32 is provided below the second start winning device 33b. The variable prize winning device 32 is configured to receive a big prize opening leading to the back of the game board 30, a shutter for opening and closing the big prize opening, a big prize opening solenoid for operating the shutter, and a game ball that has entered the big prize opening. The variable winning device 32 (large winning opening) is switched between the closed state and the open state by controlling the driving of the large winning opening solenoid and opening and closing the shutter.

  The variable winning device 32 is normally in a closed state in which a game ball cannot enter, and is in an open state in which a game ball can be won in the big hit state. It should be noted that the large winning shutter of the variable winning device 32 according to the present embodiment is pivotally supported along the lower edge of the large winning opening so that the lower edge of the large winning shutter is rotatable, and the variable winning device 32 is closed. In the state, the big winning shutter extends vertically and closes the big winning opening, so that the 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 inclined slightly downward toward the rear), and the game ball flowing down to the front of the big winning opening. Is received on the back side (upper surface) of the big prize shutter and guided to the big prize opening.

When the left and right first hold lamps are lit and the first fluctuation display is held for three times, the left first hold lamp blinks and the right first hold lamp lights and the first fluctuation When the display is held four times, the left and right first hold lamps flash. When a new game ball wins the start winning devices 33a and 33b during the big hit state, the corresponding change display is also suspended.

  In the present embodiment, the suspended variation display is digested in the suspended sequence regardless of whether the variation display is the first variation display or the second variation display. In other words, for example, the second variation display held after the first variation display already held is digested before the first variation display. Therefore, it is not a configuration in which either is preferentially digested.

  The normal symbol display device 41 is composed of two LEDs (common figure lamps). The normal symbol display device 41 is configured such that, for example, the right-side (game area outer periphery side) general-purpose lamp blinks and is displayed (variably displayed) when the game ball passes through the through gate 34. Yes. Further, after the variable display is performed for a predetermined time by the normal symbol display device 41, the variable display is stopped based on the result of the lottery support lottery. In other words, the lighting mode when the variable display is stopped (combination of the lit general-purpose lamps) is associated with various results of the entrance support lottery, and depending on the lighting mode when the variable display is stopped The result of the entrance support lottery is definitely displayed. For example, “winning” is indicated by lighting both the left and right common lamps, and “off” is indicated by lighting only the left common lamp.

  The normal hold display device 44 is composed of two LEDs (normal hold lamps). In the present embodiment, the normal symbol display device 41, which is displayed based on the passing of the game ball to the through gate 34, is configured to be able to hold and hold the variable display of up to four times. For example, when the fluctuation display on the normal symbol display device 41 is held once, the normal hold lamp on the left side (inside the game area) is lit, and when held twice, the normal left and right When the hold lamp lights up and is held three times, the left normal hold lamp blinks, and the right normal hold lamp lights and when it is held four times, the left and right normal hold lamps Flashes. In addition, when a game ball newly passes through the through gate 34 during the big hit state, the corresponding change display is also held.

  Further, the variable display device unit 35 is provided with a decorative symbol display device 42 that is configured by a liquid crystal display device and can display decorative symbols. The decorative symbol display device 42 is configured to variably display decorative symbols in accordance with the variable display by the first special display device 43a and the second special display device 43b. Furthermore, the display content of the decorative symbol display device 42 is controlled by a sub control device 262 and a display control device 45 which will be described later. That is, in the decorative symbol display device 42, the sub-control device 262 uses 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. The auxiliary display content is determined, and display is performed by the display control device 45 based on the determination.

  The decorative symbol display device 42 is provided with, for example, upper, middle, and lower three symbol display areas (upper symbol display area, middle symbol display area, and lower symbol display area), and a plurality of types of decorations are provided in each symbol display area. Symbols (for example, numerical symbols with numbers 1 to 9) are sequentially displayed (variably displayed), and then in order for each symbol display region (for example, upper symbol display region → lower symbol display region → middle symbol display) The decorative symbols are stopped and displayed (in the order of the areas). For example, when the occurrence of the big hit state is determined by the main control device 261, a display corresponding to the big hit is made on the first or second special display device 43a, 43b, and the decorative symbol is given on the decorative symbol display device 42. (For example, in the upper symbol display area, the middle symbol display area, and the lower symbol display area, the same decorative symbols are stopped and displayed in a line on the predetermined active line) Is started.

  In addition, when the decorative symbols are stopped and displayed in a combination corresponding to the jackpot, as the previous step, for example, the same decorative symbols are stopped and displayed on a predetermined effective line in the upper symbol display area and the lower symbol display area. Will be. In this way, the state where 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 being performed in the middle symbol display area is the reach state. Of course, the occurrence of a reach condition does not necessarily result in a big hit, but may be missed.

  In the present embodiment, after the reach state occurs, in the middle symbol display area, the same decorative symbol as the decorative symbol (reach symbol) stopped and displayed in the upper symbol display region and the lower symbol display region is stopped and displayed on the same effective line. When it is made (when the doublet is stopped and displayed), a big hit state is given. In addition, in the case of an odd number of eyes, “15RS” occurs, and in the case of an even number of eyes, either “15RS” or “15RN” occurs.

  In the present embodiment, a plurality of performance stages (different motifs such as backgrounds and the like) are prepared in the decorative symbol display device 42 as effects that teach or suggest the game mode in which the user is staying. More specifically, a “probability change stage” indicating that the user is staying in the probability change mode, a “normal stage” indicating that the user is staying in the normal mode, and “ There is a time reduction stage. In other words, when “15RS” is won, the process proceeds to “probability change stage” after the jackpot state ends, and when “15RN” is won, the process proceeds to “time reduction stage” after the jackpot state ends. Further, in the “time shortening stage”, when the variable display of the special display devices 43a and 43b (variable display of the decorative symbol display device 42) is performed 100 times, the process proceeds to the “normal stage”.

  In the present embodiment, the variable display of the special display devices 43a and 43b, which is performed based on the game balls entering the start winning devices 33a and 33b, is suspended (with the right to execute the variable display). However, the decorative symbol display device 42 is also taught. For example, in the hold display area which is the lower area of the display area of the decorative symbol display device 42, a hold icon indicating that the variable display is stored is displayed.

  In addition, in the lower part of the left side area and the right side area of the variable display device unit 35, a plurality of (two in each case, left and right) general along the peripheral part (inner rail constituting part 51) of the game area A winning device 31 is provided. As will be described in detail later, the general winning device 31 includes a winning port switch 221 that can detect a game ball that has entered the general winning port 31.

  The game board 30 includes an inner rail component 51 and an outer rail component 52, and a rail 50 that guides a game ball launched from the launch device 60 to the upper part of the game board 30 is attached. As a result, the game balls fired in accordance with the turning operation of the handle 18 are guided through the launch rail 61 and the rail 50 into a game area formed between the game board 30 and the glass unit 137.

  A return ball preventing member 53 is attached to the tip portion of the inner rail constituting portion 51 (the upper left portion in FIG. 4). This prevents a situation in which the game ball once guided from the rail 50 to the game area returns to the rail 50 again. Further, a return rubber 54 is attached to a substantially distal end portion (upper right portion in FIG. 4) of the outer rail constituting portion 52. The game ball fired at a predetermined momentum or more hits the return rubber 54 and is returned to, for example, the substantially central portion of the game board 30.

  In the present embodiment, the outer rail component 52 is interrupted at the upper right portion of the game board 30, and the inner rail component 51 is interrupted at the lower right portion of the game board 30. For this reason, the game area is defined by the inner peripheral surface of the rail 50 and the window hole 39 of the resin base 38. However, since the game ball launched by the launching device 60 may flow backward through the rail 50 until it passes through the return ball prevention member 53, the parallel portions of the inner and outer rail constituting portions 51 and 52 are excluded from the game area. It is burned.

When the front frame set 14 is opened, the shutter 68 protrudes forward by an urging force of a spring or the like so that the outlet of the payout passage 67 is almost closed. ing. When the front frame set 14 is closed, the shutter 68 is pushed open by the inlet side rear end of the lower plate communication path 71. In addition, the inlets (sphere inflow portions) of the lower plate communication passage 71 and the upper plate communication passage 73 are adjacent to each other, and in the closed state of the front frame set 14, each of the inlets and the discharge passage 67 are separated by a predetermined distance. A game ball can pass through the gap between the two. For this reason, when the upper plate 19 and the upper plate communication passage 73 are filled with game balls, the game balls to be dispensed flow to the lower plate communication passage 71 side (overflow to the inlet side of the lower plate communication passage 71), and the lower plate connection It will be paid out to the lower plate 15 through the passage 71.

  In addition, the ball path unit 70 is provided with a full detection switch (not shown) that detects a game ball located in the lower dish communication path 71. Due to the presence of the full detection switch, it is grasped that the lower plate 15 is full of game balls (the lower plate 15 is full of game balls and the game balls are retained in the lower plate communication path 71). be able to. In the present embodiment, based on the fact that a game ball is continuously detected for a predetermined time by the full detection switch, an error notification that teaches that the lower plate 15 is full using a display or sound on the decorative symbol display device 42 is used. Is controlled. When the game ball stays in the lower tray communication path 71 and the game ball is not detected by the full detection switch (when it is not detected continuously for a predetermined time), the error notification state is canceled.

  Further, a member (frame cover 213 or the like) attached to the rear surface of the game board 30 is attached to the game board main body 401 and is not attached to the base portion 405 (it may be in contact with the rear surface of the base portion 405, but the screw Etc.). Thus, the board surface replacement unit 404 can be removed from the game board body 401 relatively easily without removing the members on the rear side of the game board 30 from the game board 30.

  Further, as shown in FIG. 9, on the rear side of the game board 30, the cell image 412 is partially attached not only to the rear face of the game board main body 401 but also to the rear face of the base portion 405. However, in this example, the cell image 412 is separately attached to the game board main body 401 and the base portion 405, and the base portion 405 is fitted into the base portion opening 403 so that both cell images 412 are displayed. The symbols are connected (continuous) without any step difference. In addition, there is no member that can be attached to 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 nails 406 provided on the base portion 405 is provided. When the game nail 406 of the board replacement unit 404 is damaged or the like, and the game nail 406 is replaced, the base portion 405 (a part of the game board 30) is replaced. That is, conventionally, when the broken game nail 406 is removed from the game board 30, a stick-shaped tool is applied to the game nail 406 remaining inside the game board 30 from the front side of the game board 30, and the tool is hammered. The broken nail was pushed out to the rear side of the game board 30. Further, when the game nail 406 is newly attached, the game nail 406 is hit against the game board 30 with a hammer. For this reason, when the game nail 406 is replaced, a relatively large impact is applied to the game board 30, so that the other parts of the pachinko machine 10 are not damaged due to the impact. The game nail 406 was replaced after the various game members and the like were removed from the game board 30 and the game board 30. Accordingly, it involves work such as attachment / detachment of various members and attachment / detachment of wiring, which requires a great amount of labor and increases the risk of work mistakes. It is also feared that the game board 30 and the rear side member are dropped and damaged.

Accordingly, it is possible to replace the game nail 406 by simply removing the center frame 47 from the game board 30 and attaching the game board 30 to the main body (inner frame 12) of the game machine 10. The occurrence of mistakes is suppressed, and even if an error occurs, the situation until the game board 30, the game nail 406, and the game members around it are damaged (for example, the front of the game board 30 or the game nail 406 with a hammer) It can be configured so as not to cause a situation such as hitting and damaging it. As a result, it is possible to improve workability when replacing the game nail 406, reduce the risk of damage to the game board 30, the game nail 406, and the like.

  In addition, the base portion 405 of the board surface replacement unit is less restrictive in shape than the game nail 406, and the shape of the attachment site for the game board main body 401 can be designed relatively freely. In the present embodiment, the base portion 405 includes a mounting portion 432 attached to the center frame 47 using screws 422 and a positioning portion formed on the inner peripheral surface of the base portion opening 403 of the game board 30. A positioned portion 435 that is in contact with 425 and is positioned in the front-rear direction. For this reason, the game nail 406 of the board surface replacement unit 404 is sufficiently stable in the attached state to the game board main body 401, for example, compared with the game nail 406 directly attached to the game board main body 401. The nail 406 can be easily removed from the game board 30 (game board main body 401). Therefore, when the game nail 406 is removed from the game board 30, the place where the game nail 406 is attached to the game board 30 is damaged, and it is preferable to attach a new game nail 406 to the place. Is not attached (the lower hole 431 is widened when the game nail 406 is pulled out, and the game nail 406 cannot be attached as it is. It is possible to avoid a situation in which the position of the game nail 406 is shifted from the original position in the hole 431 and the scar remains and causes a decrease in design. it can. As a result, the game nail 406 can be exchanged accurately and relatively easily, and the accuracy and workability 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 can be visually recognized through the game board 30, for example, when the game nail 406 is removed from the game board 30, the game board 30 If the rear surface or the inside of the machine is damaged, such a damaged part is visually recognized, and there is a concern that the design property is deteriorated. In this regard, with respect to the game nails 406 of the board surface replacement unit 404, the entire upper panel surface replacement unit 407 to be replaced together with the base portion 405 to which the game nails 406 are attached is relatively relatively smooth. Therefore, 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. Accordingly, 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 the design property is deteriorated.

  In addition, the game board 30 made of polycarbonate is harder than the game board made of conventional plywood, and there is a concern that the game nail 406 may break easily due to this. In addition, the game board 30 has a strong force to hold the game nail 406, and it becomes difficult to remove the game nail 406 (which remains broken inside the game board 30) from the game board 30, and the game board 30 is damaged. There is also concern that In this regard, as in this embodiment, the board surface replacement unit 404 is provided so that the game nail 406 can be replaced accurately and relatively easily, so that the number of opportunities for replacing the game nail 406 has increased. However, sufficient maintenance can be handled.

  Further, 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. For this reason, for example, the base portion 405 protrudes rearward from the rear surface of the game board 30, thereby obstructing the arrangement of various members (various control devices, etc.) provided on the rear surface side of the game board 30 by the board surface replacement unit 404. (In this example, it is possible to avoid a situation in which the frame cover 213 or the like cannot be attached). In other words, it is possible to reduce a situation in which the part where the board surface replacement unit 404 can be installed is limited by the arrangement of various members provided on the rear side of the game board 30, and to a desired position (game area) A board surface replacement unit 404 can be installed (for convenience of arrangement of various game members on the side). Furthermore, the cell image pasted on the rear surface of the game board main body 401 and the cell image pasted on the rear surface of the base portion 405 can be made flush with each other, and the game visually recognized through the transparent game board 30 The visual recognition mode on the rear side of the 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. For this reason, it is possible to prevent a situation in which the game ball flowing down from above the game nail 406 of the board surface replacement unit 404 along the front surface of the game board 30 collides with the upper surface of the base portion 405. Therefore, a malfunction caused by the game ball colliding with the upper surface of the base portion 405 and jumping forward or the like (for example, the ball collides with the glass unit 137 in front of the game area to generate noise, or the movement path of the game ball) Can be avoided and a winning device (such as deviating from the first start winning device 33a) can be avoided. Furthermore, due to the collision of the game ball with the upper surface of the base portion 405, the base portion 405 is damaged, or the mounting state of the base portion 405 is adversely affected (the base portion 405 and thus the game nail 406 is inclined). It is possible to avoid the situation that occurs. In addition, the impression between the pachinko machine 10 and the gaming machine maker may deteriorate due to the formation of a step between the base part 405 and the gaming board body 401 (may be a defective product that has been cut by hand) It is possible to prevent such a situation that the designability is lowered.

  In addition, since the base portion 405 that is a part of the game board 30 is a separate piece from the game board main body 401, the design of the game board 30 can be changed relatively easily in the base portion 405. For example, the color of the game board main body 401 is used for a predetermined purpose such as to be a mark of the target position of the game ball (so that the main part can be noticed) or to make the game ball easier to see. It is relatively easy to make variations and functions of the game board 30 relatively different from each other, or to integrally form a portion where a predetermined member can be attached, locked, and supported on the rear surface side of the base portion 405. It becomes possible to increase to. Accordingly, it is possible to improve functionality and design. In addition, for example, when changing the model, it is relatively easy to change the arrangement of game members such as game nails and winning holes and to change the information means such as model information by changing the board replacement unit. Can be done. In this example, information specific to the pachinko machine 10 (information different for each model, subtitle and center frame 151) is displayed on the front surface of the base portion 405 of the upper board surface replacement unit 407 and the horizontal board surface replacement unit 408. A sticker printed with information indicating the position of the entrance 151 of the warp channel 152 is attached, and the base portion 405 of the lower board surface replacement unit 409 is colored to suppress light transmittance. (Consists of colored transparent resin).

  Further, in this embodiment, positioning is performed by a positioning portion 425 having a substantially triangular convex cross section of the game board main body 401 and a positioned portion 435 having a substantially triangular concave cross section of the base portion 405, and a base portion with respect to the game board main body 401. Relative displacement of 405 forward and backward is prevented. For this reason, the number of screws 422 used for attaching the board surface replacement unit 404 to the game board main body 401 and the center frame 47 and the installation location are reduced. In particular, the panel surface replacement unit 401 and the game board main body 401 are connected. Screw can be eliminated. Therefore, it is possible to improve the workability of attaching and detaching the panel surface replacement unit 404 and to suppress the deterioration of the design property due to the visual recognition of the screw. In addition, in this embodiment, since the game board main body 401 and the base part 405 are transparent, the screw 422 is used for connection between the game board main body 401 and the base part 405, so that the screw is passed through the game board 30. The entire 422 (all parts embedded in the game board 30) are visually recognized (the screw 422 appears to float), and a situation in which designability is deteriorated or uncomfortable can be prevented.

  Furthermore, since the positioning part 425 and the positioned part 435 have a substantially triangular cross section, for example, the board surface replacement unit is compared with the case where one of the positioning part and the positioned part has a substantially rectangular cross section. When a force is applied in the front-rear direction to the base portion 405 of 404 or the portion of the game board main body 401 adjacent to the base portion 405 (a shearing stress is applied to the positioning portion 425), the positioning portion 425 or A situation in which the positioned portion 435 is damaged (broken) can be suppressed. Further, when the positioning portion 425 and the positioned portion 435 are abutted with each other, one of the positioning portion 425 and the positioned portion 435 is placed on the other slope without matching the positions in the front-rear direction. As a result, the relative displacement is made to an appropriate position. Therefore, it is possible to improve the mounting workability of the panel surface 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 be positioned in contact with the entire circumference of the positioning portion 425. For this reason, positioning with the base part 405 and the game board main body 401 can be performed more firmly. Also, for example, a part of the outer peripheral surface of the base portion 405 facing the inner peripheral surface of the base portion opening 403 of the game board main body 401 is orthogonal to the front surface of the game board 30 (game board 30 (in the thickness direction) (when the portion is not the positioned portion 435), the back of the gaming board 30 can be seen at the boundary portion (matching portion) with the gaming board main body 401 of the surface. There is a concern that such a gap may be formed. In this regard, by positioning the entire inner periphery of the base portion opening 403 of the game board main body 401 as the positioning portion 425 and positioning with the positioned portion 435 over the entire inner periphery, the positioning portion 425 and the position to be positioned over the entire inner periphery. Since the part 435 overlaps with the front-back direction, this concern can be wiped out.

  Further, when the positioning portion 425 is formed over the entire inner peripheral surface of the base portion opening 403, the base portion 405 is attached to the base portion opening 403 of the game board main body 401 by being relatively displaced in the front-rear direction. However, in this embodiment, since the through hole 402 for attaching the variable display device unit 35 is formed adjacent to the base portion opening 403, the base portion 405 is mounted from the through hole 402 to the base. It can be inserted into the opening 403 for part.

  Further, a screw 422 (for example, a flat head screw) having a head 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 part 405 from the front through the frame side mounting hole 423 of the mounting piece 421. For this reason, when the game nail 406 of the board surface replacement unit 404 is replaced, the screw 422 is screwed to the base part 405 of the new board surface replacement unit 404. For example, the screw 422 is attached to the base part. As in the case of adopting a configuration in which the base portion 405 is penetrated from the 405 side and screwed to the center frame 47, the frame side mounting hole of the center frame 47 is loosened, and the screw 422 is preferably used. It is possible to avoid the possibility that it cannot be screwed.

  Further, the center frame 47 is made of an opaque resin, and the screws 422 that connect the center frame 47 and the base portion 405 are provided on the opaque mounting piece 421, so that the screws 422 are not so noticeable. In addition, 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, so that the game nail 406 can be removed (so as not to be dropped or displaced) during the mounting operation of the screw 422. ) The screw 422 can be screwed while being held and supported by hand (for example, as compared with the case where the mounting piece 421 is positioned behind the base 405 and the screw 422 is mounted from the rear). Improvement is achieved.

(Second Embodiment)
Hereinafter, a second embodiment will be described. As shown in FIGS. 10 and 11, in the second embodiment, a variable display device unit 35 having a plurality of patterns having different shapes with respect to the game board 30 (game board main body 442) using a board surface replacement unit 441. A center frame 47) can be attached. More specifically, as shown in FIG. 10, the game board 30 has a center frame 47 that is located in the center of the game board 30 and that has a front view shape of a game area in which a game ball can move substantially symmetrically. (Hereinafter, referred to as a left-right symmetric frame 443), as shown in FIG. 11, a center frame 47 (hereinafter referred to as a right expansion frame 444) that looks like the left-right symmetric frame 443 is expanded to the right side of the game area. ) And can be attached. The vertical width of the right extension frame 444 is larger than the vertical width of the left-right symmetric frame 443. 10 and 11, the illustration of the game nail 456 and the like of the game board main body 442 is omitted.

  A through hole 445 for attaching the right extension frame 444 is formed in the game board main body 442.

With 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. Then, the right extension frame 444 is attached to the game board main body 442 by screwing the screws 449 into the screw holes 448 from the front via the frame side attachment holes 447. In this embodiment, when the right extension frame 444 is mounted on the game board main body 442, the board surface replacement unit is not used.

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

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

  On the other hand, as shown in FIG. 12, the base portion 451 of the panel surface replacement unit 441 is formed with a positioned portion 454 having a substantially triangular concave section that fits into the positioning portion. In addition, 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) in which one is fitted to the other. Yes.

  Then, after the base portions 451 of the two panel surface replacement units 441 are sequentially fitted to the right extension portion 452, the left-right symmetric frame 443 is inserted into the through hole 445, and the mounting pieces 446 of the left-right symmetric frame 443 are inserted. Are brought into contact with the front surfaces of the game board main body 442 and the base portion 451. Furthermore, the left and right symmetric frame 443 is attached to the game board 30 by connecting the game board main body 442 and the base portion 451 and the attachment piece 446 with the screws 449.

  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 section in the game board body 442. In this way, it extends obliquely toward the inner peripheral side of the through hole 445 toward the rear. Also, as shown in FIGS. 12 and 13, among the outer peripheral surfaces of the left-right symmetric frame 443 and the right extension frame 444, the inner peripheral surface of the through-hole 445 (the positioning portion 453 formed) and the mounting portion of the base portion 451 The part facing the side surface of 455 extends inclining 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 the present embodiment, there is a portion where the positioning portion 453 and the outer peripheral surfaces of the left-right symmetric frame 443 and the right extension frame 444 are opposed to each other. Has been.

  In addition, as shown in FIG. 12, when attaching the symmetrical frame 443 to the game board main body 442, as shown in FIG. 13, a screw 449 for attaching the right extension frame 444 to the game board main body 442 is screwed. Of the screw holes 448, those provided in the periphery of the right extension portion 452 are unnecessary. In this embodiment, the lower hole 457 for attaching the game nail 456 and the screw hole 448 formed in the game board main body 442 have the same shape (hole diameter), and the game board main body 442 has a symmetrical frame. When the 443 is mounted, the game nail 456 is configured to be attached to the screw hole 448 that is not used for the attachment of the symmetrical frame 443 to the game board main body 442. In other words, the mounting piece 446 of the right extension frame 444 is formed with a frame side mounting hole 447 corresponding to one of the lower holes 457 to which the game nail 456 is mounted when the left and right symmetrical frame 443 is mounted on the game board main body 442. Has been.

  In the present embodiment, the right extension frame 444 corresponds to the first specific game member, and the left-right symmetric frame 443 corresponds to the second specific game member. Furthermore, the state in which the right extension frame 444 is mounted on the game board main body 442 corresponds to the first use state, and the state in which the left-right symmetric frame 443 is mounted on the game board main body 442 corresponds to the second use state. In addition, the frame side mounting hole 447 corresponds to the member side mounting hole, and the lower hole 457 into which the screw 449 for mounting the right expansion frame 444 is screwed out of the lower hole 457 of the game board main body 442 is the board side mounting hole. It corresponds to.

  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 mounting the left-right symmetric frame 443 on the game board main body 442, mounting the pilot hole 457 used for attaching the game nail 456 to the game board main body 442 and mounting the right extension frame 444 on the game board main body 442. In addition, the right extension frame 444 is configured to be used as a screw hole 448 into which a screw 449 for attaching the right extension frame 444 to the game board main body 442 is screwed.

  For this reason, when the right extension frame 444 is mounted, a screw hole 448 for attaching the right extension frame 444 to the game board main body 442 is separately required (when the right extension frame 444 is used, the screw hole 448 is bothered. Can be avoided. Further, in the game board main body 442, the screw hole 448 for attaching the right extension frame 444 to the game board main body 442 is not used in a state where the left-right symmetric frame 443 is mounted (the screw hole 448 which is not used exists, ), It is possible to avoid a situation in which a sense of incongruity or the like is caused or the design property is deteriorated.

  In the present embodiment, the angles of the surfaces to be abutted on the outer peripheral surface of the left-right symmetric frame 443 or the right extension frame 444, the outer peripheral surface of the base portion 451, and the inner peripheral surface of the through hole 445 are aligned. It is comprised so that it may contact | abut on a surface. For this reason, compared with the structure which cannot make these contact | abut on a surface, for example, stabilization of an attachment state, reduction of damage risk, etc. can be aimed at.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

It is good.

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

  In addition, the upper portion of the base portion 405 is configured to be located slightly rearward of the front surface of the game board 30, and the lower portion of the base portion 405 is configured to be slightly forward of the front face of the game board 30. It may be configured. In this case, at the boundary portion between the front surface of the game board main body 401 and the front surface of the base portion 405, the upper portion is configured to be positioned at the front side. It is possible to reliably avoid the formation of a step where the game balls come into collision. It should be noted that it is desirable to configure the base portion 405 so that the portion including at least the upper side portion of the front surface is flush with the front surface of the game board body 401 or behind the front surface of the game board body 401. Here, the “upper side portion of the front surface of the base portion” intends the front side portion of the surface that is visible when the base portion is viewed from above.

  Further, a cable holder for hooking the wiring may be provided on the rear surface side of the base portion 405 so as to protrude rearward from the rear surface of the game board main body 401. In this case, for example, by providing the cable holder along the arrangement of the game nail, the wiring extends along the arrangement of the game nail, and the wiring visually recognized through the base portion 405 is made as inconspicuous as possible by the game nail. It can also be done. Further, on the rear surface side of the base portion 405, a locking means for locking the decorative accessory is provided (for example, a direction in which the pair of left and right locking pieces and the pair of locking pieces are separated from each other). It is good also as providing the latching claw which protrudes in the. In this case, a decorative accessory can be visually recognized through the transparent base portion 405. The cable holder, the locking means, etc. may be formed integrally with the base portion 405, or may be configured separately and attached by locking, press-fitting, screwing, bonding, or the like. Good.

  (B) In the above-described embodiment, the board surface replacement unit 404 in which the game nail 406 is attached to the base portion 405 is embodied, but the board surface replacement unit 404 in which another game member is attached to the front surface of the base portion 405. You may apply to. For example, the board surface replacement unit 801 shown in FIG. 14 is provided corresponding to a substantially rectangular base portion 802 and a winning hole 803 formed in the base portion 802, and receives a game ball moving in the game area to win a prize.

The ball receiving portion 804 is fixed to the base portion 802 with screws on the rear surface side of the base portion 802. In this example, the base portion 802 and the ball receiving portion 804 are made of a colorless and transparent resin (a seal (not shown) is attached to the front surface of the ball receiving portion 804). In addition, a first start winning switch that detects a game ball that has entered the ball receiving portion 804 is provided in a portion of the ball receiving portion 804 on the rear side of the base portion 802. Note that the ball receiving portion 804 may be formed integrally with the base portion 802.

  The base portion 802 is formed with a positioned portion 806 having a substantially triangular convex section along the left and right side portions and the lower side portion, and is formed on the inner peripheral surface of the base portion opening portion of the game board main body (not shown). The positioning section having a substantially triangular concave shape is fitted. Further, a base side mounting hole (not shown) into which a screw 808 for mounting the base portion 802 to the mounting piece 807 of the center frame 47 is screwed is formed in the vicinity of the upper right corner and the upper left corner of the base portion 802. ing. Then, after the base portion 802 is inserted into the base portion opening so that the positioned portion 806 is fitted to the positioning portion, the center frame 47 is inserted through the through hole of the game board main body (not shown) from the front. The mounting piece 807 of the center frame 47 is brought into contact with the front surface of the base portion 802. In such a state, the frame side mounting hole (not shown) formed in the mounting piece 807 for inserting the screw 808 matches the base side mounting hole of the base portion 802. A screw 808 is screwed into the base side mounting hole from the front mounting piece 807 side through the frame side mounting hole. As a result, the panel surface replacement unit 801 and the center frame 47 are connected.

  In addition, as a gaming member of the board surface changing unit 404, it may be applied to other gaming members such as a windmill nail, a through gate 34, a start winning device 33b, and a variable winning device 32. Furthermore, the combination when a plurality of types of game members are mounted on one base portion 405 can be set as appropriate.

  In addition, when a winning device is adopted as the game member, the base portion 802 to which the ball receiving portion is attached is formed in a disc shape, and the base portion 802 is provided so as to be rotatable with respect to the game board main body (the positioning portion and the target portion). The positioning portion may be configured as a rail extending in an arc shape), and may be configured to continue to rotate when the pachinko machine 10 is powered on (or in a predetermined hit state). A game ball entered when the opening of the ball receiving portion is upward is guided to the rear of the base portion 802 and provided in a receiving passage for receiving a game ball flowing from the ball receiving portion with the opening facing upward. A game ball may be detected by the entered ball detection switch. Furthermore, as the shape of the game board main body side in the case of adopting such a configuration, for example, a base part opening part into which a base part 802 equipped with a winning device can be inserted, and a base part opening part and a through hole are provided. A communication portion to be communicated (formed in a shape like a part of a long hole), a positioning portion is formed on the entire inner surface of the opening for the base portion and the communication portion, and from the through hole side via the communication portion After the base portion 802 equipped with the winning device is inserted through the base portion opening, the communication portion has a shape that just fits into the communication portion and constitutes a part of the game board 30 and is also provided with game nails. The base part of the corresponding panel surface replacement unit is inserted into the communication part from the through hole side. The base part of the communication part corresponding panel replacement unit is for a base that rotatably supports a positioned part that fits the positioning part of the communication part and a positioned part that is formed on the outer periphery of the base part 802 mounted with the winning device. A positioning portion of the opening and a support portion having the same shape in cross section are formed.

It has become. The screw 822 (a countersunk screw) that connects the base portion 812 and the game board main body 817 is also configured not to protrude rearward from the rear surface of the game board main body 817.

  As described above, the board surface replacement unit 811 is attached to the game board body 817 only with the screws 822, so that the board surface can be positioned not adjacent to the specific game member attached to the opening of the game board 30 such as the center frame 47. The replacement unit 811 can be attached independently. In addition, since the screw 822 for attaching the board surface replacement unit 811 to the game board body 817 is attached from the rear side of the game board 30, the screw 822 is provided on the front surface although the game board body 817 and the base portion 812 are transparent. The screw 822 can be made inconspicuous compared with the case where it is attached to the side. Furthermore, since the flange portion 815 is on the rear side of the game board 30, the area of the base portion 812 on the front side of the game board 30 can be reduced as much as possible, and at the boundary between the base portion 812 and the game board body 817. It is possible to reduce the possibility that the traveling direction changes (forward) when the game ball hits.

  (C-2) Further, for example, as shown in FIGS. 16 and 17, a board surface replacement unit 832 on which only one game nail 831 is mounted may be embodied. More specifically, as shown in FIGS. 16 (a) and 17, the base portion 833 of the panel surface changing unit 832 has a cylindrical shape having a nail hole 834 for attaching the game nail 831 to the center portion. A main body portion 836 having a threaded portion 835 formed on the outer peripheral surface, and a substantially disk having a diameter larger than that of the main body portion 836, provided on the end side opposite to the side on which the game nail 831 protrudes in the main body portion 836. And a head 837 having a shape. 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 panel surface changing unit 832.

  On the other hand, as shown in FIG. 17, the game board main body 844 can accommodate the main body portion 836 of the base portion 833, and has a main body having a threaded portion 841 that is screwed to the screw portion 835 of the main body portion 836. A base portion opening 843 is formed that includes a housing portion 839 and a head housing portion 842 that can house the head portion 837. Then, until the head 837 is accommodated in the head accommodating portion 842 and abuts, the base portion 833 is screwed to the game board main body 844, so that the board surface replacement unit 832 is attached to the game board main body 844.

  In this embodiment, 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) on the front surface of the base portion 833. . Further, when the board surface replacement unit 832 is attached to the game board main body 844, the front surface of the base portion 833 is flush with the front surface of the game board main body 844, and the rear surface of the base portion 833 is flush with the rear surface of the game board main body 844.

In particular, it is possible to exchange the game nail 831 at a pinpoint, such as applying the board replacement unit 832 as a game nail 831 (life nail) in the vicinity of the first start winning device 33a, and there is no need to replace it. It is possible to avoid waste such as replacement of the game nail 831 and the like.

  Further, since the distance between the outer peripheral surface of the main body portion 836 of the base portion 833 and the nail hole 834 is less than the radius of the game ball on the front side of the game board 30, the game ball is placed on the base portion 833. And cannot contact the boundary with the game board main body 844. Accordingly, the game ball moving along the front surface of the game board 30 collides with the boundary between the base part 833 and the game board main body 844, and the course of the game ball may be greatly changed (frontward). It is possible to reliably avoid a situation in which the base portion 833 damages the game board main body 844 at the boundary portion. In this embodiment, the entire front surface of the base portion 833 corresponds to the riding-up prevention area.

  In addition, about the structure which makes the distance between the outer periphery of the front surface of the base part 833, and game members, such as the game nail 831, less than the radius of a game ball, it is also possible to materialize to another board surface exchange unit 404. It is. For example, in the board surface replacement unit 811 as shown in FIG. The panel surface replacement unit 811 may be provided at a position where the panel approaches 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 may be opaque or other such as wooden (plywood) You may comprise with the material of. Further, the game board main body 401 and the base 405 may be made of different materials. For example, the game board main body 401 may be made of plywood, and the base portion 405 may be made of a transparent resin. Further, the base portion 405 may be formed by mixing a resin with fine beads or lame sheets, or a figure or the like may be embedded in the base portion 405. In addition, illumination means for irradiating the base portion 405 with light from behind or the like may be provided (for example, the hue, the color tone, and the brightness may be changed so that the relative displacement is possible).

  (E) In the above embodiment, the entire thickness direction of the positioning portion 425 of the game board body 401 has a substantially triangular convex section, and the entire thickness direction of the positioned portion 435 of the base section 405 has a generally triangular concave shape. However, it is not limited to such a shape. For example, the positioning section 425 and the positioned section 435 having a substantially triangular convex shape and a triangular concave section are provided only at the center in the thickness direction of the game board main body 401 and the base portion 405, and the inner peripheral surface of the base portion opening 403 and the base In the mating surface with the outer peripheral surface of the part 405, the front part and the rear part may be configured to extend along the thickness direction of the game board 30 (in a direction orthogonal 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 403 of the game board main body 401 are sharp and easily damaged. 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, or the like. Further, the positioning portion 425 may be concave and the positioned portion 435 may be convex.

However, it is only necessary that some of them are provided.

  (F) Further, for example, by making light incident on the base portion 405 of the board surface changing unit 404 from the side (from the side of the center frame 47 having a flat end surface), a predetermined mode is applied to the portion where the light is incident. You may comprise so that may surface. More specifically, the light incident from the side is bent in a direction different from the other parts with respect to the part of the base part 405 that is intended to raise the predetermined mode (all within the base part 405). A light guide plate that does not reflect and is irradiated forward is processed. Furthermore, the light emitting part is provided toward the base part 405 in a direction in which light can be irradiated to a part of the center frame 47 adjacent to the base part 405. The light emitting unit is driven and controlled by the sub-control device 262, and the lighting mode changes according to the effect or the like. Thereby, only the base part 405 of the game board 30 can be made to derive | lead-out the aspect of a light-guide plate.

  Further, for example, with respect to the mating surface of the game board main body 401 and the base part 405 of the board surface replacement unit 404, a predetermined decorative member (polarizing filter, lamellar transparent string, etc.) or the game board 30 Electrically connecting the front side and the rear side (the front side and the front side may be connected, the rear side and the rear side may be connected, or the front side and the rear side and the outer peripheral side of the game board 30 are connected. It may also be embedded so as to sandwich wiring (desirably decorated) or the like. In this case, a decorative member or the like can be embedded in the game board 30 relatively easily (if the decorative member is thick, an installation recess may be formed). Further, a positioning member extending from the game board main body 401 and the base portion 405 is provided on the rear surface side at the joint portion between the game board main body 401 and the base portion 405 of the board surface replacement unit 404 (for example, a game A concave portion extending between the board body 401 and the base portion 405 may be formed, and a positioning member fitted into the concave portion may be press-fitted). In this case, more accurate positioning can be performed.

  (G) Further, for example, in the base portion 405, a concave portion that is depressed about the thickness of the attachment piece 421 may be formed at a portion that contacts the attachment piece 421 of the center frame 47. In this case, the front surface of the attachment piece 421 can be flush with the front surface of the game board 30. Further, in the case of adopting such a configuration, by forming the attachment piece 421 of the center frame 47 only at a portion corresponding to the board surface replacement unit 404, for example, a recess for the attachment piece 421 is formed in the game board main body 401. By doing so, it is possible to avoid a situation in which the versatility of the game board main body 401 is reduced.

  (H) In the second embodiment, the right extension frame 444 that is attached to the game board body 442 without using the board surface replacement unit 441 and the two board surface replacement units 441 that are used for the game board body 442 are used. Although it is actualized in the structure which can replace the left-right symmetric frame 443 attached, it is not limited to such a structure in particular, The shape of a center frame 47 and the board surface replacement unit 441, a magnitude | size, arrangement | positioning, number Etc. can be designed as appropriate. For example, a center frame 47 attached to the game board main body 442 using one board surface replacement unit 441 and a center frame 47 attached to the game board main body 442 using two board surface replacement units 441 are provided. You may comprise so that attachment is possible.

  (I) You may implement as a pachinko machine of a different type from the said embodiment. For example, movable means that can be changed between a specific area in which a game ball moving in the game area can enter, an open state that allows entry into the specific area, and a closed state that prohibits entry into the specific area ( Variable entry means comprising wing members), specific entry means and non-specific entry means capable of entering a game ball entering a specific area, and detection of a game ball entering the specific entry means Specific entry detection means (condition establishment detection means) that performs, a start entry means that is provided outside the specific area and can enter a game ball that moves in the game area, and a game ball that has entered the start entry means And a main control means for controlling opening and closing of the variable pitching means, and when a game ball enters a specific area, the game ball is not specified and non-specific. Regardless of which ball you enter, a predetermined number of game values (game balls) will be given to the player The main control means, based on the detection of the starting entrance detection means, the small hit state in which the variable entrance means is opened once or a plurality of times for the first time, or the variable entrance means is the first Whether to generate a jackpot state in which a predetermined number of game balls enter the open state for the second time longer than the time, or until the specified number of game balls enter the open variable means, which is set in the open state. If you win or lose lottery, if you win a lottery in the winner lottery, a small hit state is generated, if you win a jackpot in the winner lottery, and if there is a detection of specific entry detection means May be applied to a gaming machine that generates a big hit state. In addition to the pachinko machines, various game machines such as an arrangement ball machine and a similar sparrow ball may be used.

[Appendix]
The technical idea that can be grasped from the above embodiment will be described below.

  A. Conventionally, for example, a pachinko machine is known as a kind of gaming machine. The pachinko machine is provided with a game board, and a game area in which a game ball launched by the launching device is guided is formed in front of the game board. In addition, on the front side of the game board, various game members such as game nails that diversify the behavior of game balls moving in the game area and winning devices that can enter game balls moving in the game area are provided. (For example, refer to JP2003-154110A).

  In addition, since the game member disposed in the game area is subjected to a load such as repeated collision of game balls, the game member may be damaged. For example, a game nail may break due to deformation caused by a collision of game balls, adjustment for returning from the bent state to the original state, deterioration due to aging (wear, etc.). is there. In this case, it is necessary to replace the gaming member.

  By the way, when a new gaming member is attached to the place where the gaming member is removed, there is a concern that the gaming member cannot be suitably attached. In other words, for example, even if you try to install a new game nail in 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 installed well, or the nail hole is filled with Even if the game nail is driven into the game nail, there is a risk that the game nail is slightly displaced from the original game nail arrangement in such a manner that the game nail is moved in a predetermined direction. Also, for example, when a winning device as a gaming member is attached to a game board with a screw, even if a new winning device is to be attached again with a screw, the screw hole is loosened and cannot be attached well. There is a possibility that even if the stuffing is carried out and the screw is screwed there, the screw is slightly displaced from the original screw arrangement in a manner that the screw is moved in a predetermined direction, and consequently the position of the winning device is slightly displaced. is there.

  The present invention has been made in order to solve the above-described problems and the like, and its purpose is to provide a gaming machine capable of improving accuracy and workability regarding replacement of gaming members arranged in a gaming area. It is to provide.

Means A-1. A launching means for launching a game ball;
A game area provided on the front side of the game board and guiding a game ball fired by the launching means;
In a gaming machine comprising a plurality of gaming members provided to project forward from the gaming board and capable of changing a moving path of a gaming ball moving in the gaming area,
A board surface replacement unit comprising the predetermined game member and a base portion to which the game member is attached;
The base part is attached in a state of being inserted into a base part opening formed in the game board (penetrating in the front-rear direction) so as to constitute a part of the game board. A gaming machine.

  According to the 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 the game member of the board replacement unit When exchanging, the base part (a part of the game board) will be exchanged. In addition, the shape of the base portion is less restricted than that of the game member, and the shape of the attachment portion with respect to the game board main body can be designed relatively freely. For this reason, the gaming member of the board surface replacement unit is, for example, a gaming member as compared to a gaming member directly attached to a gaming board (gaming board body), while ensuring sufficient stabilization in the state of being attached to the gaming board body. Can be easily removed from the game board (game board body). Therefore, when the gaming member is removed from the gaming board, for example, because the gaming member is damaged, the portion of the gaming board where the gaming member is attached is damaged, and a new gaming member is attached to the location. However, it is possible to avoid such a situation that it is not suitably attached (the position of the gaming member is shifted, etc.) or a scar is left and the designability is deteriorated. As a result, the gaming member can be exchanged accurately and relatively easily, and the accuracy and workability of the gaming member exchange can be improved.

  In addition, the design of the game board can be changed relatively easily in the base part. For example, for a predetermined purpose such as to be a mark of the target position of the game ball (so that the main part can be noticed) or to make the game ball easier to see, colors etc. To increase the variations and functions of the game board relatively easily, such as making them different, or integrally forming a part that can attach, lock, and support a predetermined member on the rear side of the base part Is possible. Accordingly, it is possible to improve functionality and design. In addition, for example, when changing the model, it is relatively easy to change the arrangement of game members such as game nails and winning holes and to change the information means such as model information by changing the board replacement unit. Can be done.

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

  According to the means A-2, for example, the base portion protrudes rearward from the rear surface of the game board, so that the arrangement of various members (such as various control devices) provided on the rear surface side of the game board by the board surface replacement unit. It is possible to avoid the situation that it is obstructed. In other words, the arrangement of various members provided on the rear side of the game board can reduce the situation where the part where the board replacement unit can be installed is limited, and can be reduced to a desired position (on the game area side). A board replacement unit can be installed (due to the arrangement of various gaming members).

  Means A-3. The means A-1 or A is characterized in that the base part has a portion including at least the upper side part of the front face flush with the front face of the game board or behind the front face of the game board. -2 gaming machine.

  According to the means A-3, the portion including the upper side of the front surface of the base portion and the front surface of the game board are flush with each other or are located behind the front surface of the game board. It is possible to prevent a situation in which the game ball flowing down from above the gaming member of the board surface replacement unit collides with the upper surface of the base portion. Therefore, a malfunction caused by the game ball colliding with the upper surface of the base portion and jumping forward or the like (for example, it collides with the glass unit in front of the game area and noise is generated, or the movement path of the game ball is large. It can be avoided that the winning means are changed and the like. 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 advanced comfortably.

  Furthermore, due to the impact of the game ball on the upper surface of the base part, the base part may be damaged, or the mounting state of the base part may be adversely affected (the base part and thus the gaming members may be tilted). Can be avoided. In addition, there is a difference in level between the base and the game board itself, which may worsen the impression of the gaming machine and the gaming machine manufacturer (whether it is made by hand or is not defective) Etc.), and it is possible to prevent such a situation that the design property is lowered.

  The “upper side portion of the front surface of the base portion” is intended to be a front side portion of a surface that is visible when the base portion is viewed from above, and “a portion including the upper side portion of the front surface of the base portion”. As for, it is desirable to include the whole of the front side part, but it may be a part, depending on the shape of the base part and necessity (whether it is a path through which a game ball may pass) It can be designed as appropriate.

Means A-4. It is arranged so as to penetrate through the opening formed in the game board, and includes a specific game member attached to the game board using an attachment member,

It is possible to reduce the number of installation members and installation locations, and in particular, to eliminate the installation members for connecting the board surface replacement unit and the game board main body. Therefore, it is possible to improve the workability of attaching and detaching the panel surface replacement unit, and it is possible to suppress the deterioration of the design property due to the visual recognition of the mounting member.

  Means A-5. One of the positioning portion and the positioned portion has a convex portion having a substantially triangular cross section, and the other has a concave portion having a generally triangular cross section that fits the convex portion. A gaming machine according to A-4.

  According to the means A-5, forward and backward relative displacement can be more reliably prevented. In addition, for example, compared to the case where one of the positioning portion and the positioned portion has a substantially rectangular cross section, the base portion of the board surface replacement unit or the portion adjacent to the base portion of the game board main body On the other hand, when a force is applied in the front-rear direction (a shear stress is applied to the positioning portion), it is possible to suppress a situation in which the positioning portion or the positioned portion is damaged (ruptured). Further, when the positioning portion and the positioned portion are abutted with each other, one of the positioning portion and the positioned portion is guided to the other slope without matching the positions in the front-rear direction completely. Thus, the relative displacement is made to the proper position. Therefore, it is possible to improve the mounting workability of the panel surface replacement unit.

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

  According to the means A-6, the positioning of the base part and the game board main body can be performed more firmly. In addition, for example, a part of the outer peripheral surface of the base portion that faces the inner peripheral surface of the base portion opening of the gaming machine body is orthogonal to the front surface of the game board (the thickness direction of the game board). When the surface is extended to the surface (when it is a portion that is not a positioned portion), a gap is formed at the boundary portion (matching portion) between the surface and the gaming machine main body so that the back of the game board can be seen. There are concerns. In this regard, by positioning the entire inner circumference of the base board opening of the game board main body as a positioning portion and positioning with the positioned portion over the entire inner circumference, the positioning portion and the positioned portion over the entire inner circumference This overlaps the concerns.

  Further, when the front and rear positioning is performed by the positioning portion and the positioned portion as in the means A-5, the base portion is relatively displaced in the front-rear direction with respect to the base portion opening of the game board main body. However, since the opening for the specific game member is formed adjacent to the opening for the base portion as in the means A-4, the base portion is opened for the specific game member. It is possible to insert into the opening for the base part from the part.
