Therefore, a decorative seal or the like is attached to the installation portion of the ball rental operation unit 120. Thereby, the common use of the lending operation unit of the pachinko machine using the card unit and the cash machine can be achieved.

  As shown in FIG. 2, the game board 30 is made of a plywood having a quadrangular shape when viewed from the front, and its peripheral edge is attached in contact with the back side of the resin base (not shown) of the inner frame 12. A gaming area 30a, which is a substantially central portion on the front side of the game board 30, is visible from the front side of the inner frame 12 through the resin-based substantially elliptical window portion 101 (glass plate 137) shown in FIG. ing.

  Next, the configuration of the game board 30 will be described with reference to FIG. The game board 30 includes a general winning port 31, a variable winning device 32, first starting ports 33a and 33b (for example, operation chucker), a second starting port 34 (for example, a through gate), a variable display unit 35, and the like. Yes. These general winning port 31, variable winning device 32, first starting ports 33a and 33b (for example, operation chucker), second starting port 34 (for example, through gate), variable display unit 35, etc. Each of the through holes formed by router processing is disposed in each through hole, and is attached from the front side of the game board 30 with a wood screw or the like. A game ball enters the aforementioned general winning port 31, variable winning device 32, and first start ports 33a and 33b, and the detected balls are detected by detection switches (winning port switch, count switch, operation port switch) described later. Based on the output of the detection switch, a predetermined number of prize balls are paid out to the upper plate 19 (or the lower plate 15). As described above, the first start port 33a on the upper side is provided with an operation port switch (passage detection switch), and a ball entering the first start port 33a is detected by the operation port switch. It is like that. Further, the first start port 33b on the lower side is also provided with an operation port switch (passage detection switch), and the ball entering the first start port 33b is detected by the operation port switch. . That is, in either case of entering a game ball into the first start port 33a on the upper side or entering a game ball into the first start port 33b on the lower side, it is a start prize. There is no change. The upper first start port 33a and the lower first start port 33b are configured by a single start winning device 33 as shown in FIG.

  In addition, as shown in FIG. 2, the game board 30 is provided with an out port 36, and game balls that have not entered the various winning devices or the like pass through the out port 36 in a ball discharge path (not shown). You will be guided to the direction. A number of nails are planted on the game board 30 in order to appropriately disperse and adjust the falling direction of the game balls, and various members (acts) such as the windmill 37 are arranged.

  The variable display device unit 35 includes a first symbol display device 40 for variably displaying a first symbol (for example, a special symbol) as identification information, triggered by winning in the first start ports 33a and 33b, and a second start. With the passage of the mouth 34 as a trigger, the second symbol display device 41 that variably displays the second symbol (for example, a normal symbol) and the winning of the first start ports 33a and 33b as a trigger, the third symbol (for example, a decorative symbol) ) In a variable manner.

  The first symbol display device 40 includes, for example, a plurality (two in this embodiment) of two-color light emitting type LEDs (light emitting diodes) 40a and 40b, and a hold indicating the number of hold of the variable display on the LEDs 40a and 40b. And a lamp 40c. The LEDs 40a and 40b can emit light in red and blue, for example. The first symbol display device 40 generates a variable display state of the first symbol (in this embodiment, the emission color mode of each LED 40a, 40b) by alternately changing the emission color of each LED 40a, 40b, for example, When both LEDs 40a and 40b stop in a red light emitting state, a probable big hit (specific hit) is indicated, and when both LEDs 40a and 40b stop in a blue light emitting state, a normal big hit (non-specific hit) is indicated, and both LEDs 40a and 40b are mutually connected. When it stops in the light emission state of a different color, it will show off.

  In addition, as this 1st symbol display apparatus 40, you may employ | adopt the single LED of the type which can light-emit at least 3 colors or more, and by performing light emission of each color alternately, the 1st symbol is displayed. When the LED stops in the light emission state of the first color, it shows a probable big hit (specific hit), and when the LED stops in the light emission state of the second color, it usually shows a big hit (non-specific hit) When the LED stops in the light emission state of the third color, it may be indicated that the LED has come off. The first symbol display device 40 described above corresponds to the identification information fluctuation display means in the present invention.

  The second symbol display device 41 includes, for example, a display unit 41a on which “○” is drawn for the second symbol, a display unit 41b on which “x” is drawn for the second symbol, and a holding lamp 41c. When the game ball passes through the second starting port 34, for example, the display symbols (ordinary symbols) displayed by the display units 41a and 41b change, and when the change display stops at a predetermined symbol, the lower side One start port 33b is configured to be in an activated state (opened) for a predetermined time. The number of times that the game ball has passed through the second start port 34 is held up to a maximum of 4 times, and the number of times the game ball is held is lit on the hold lamp 41c. The display units 41a and 41b have LEDs (light emitting diodes) inside thereof, and are configured to be variably displayed by switching the light emission of the LEDs (or lighting of the lamps). The second symbol display device 41 described above corresponds to the normal identification information fluctuation display means in the present invention.

  The 3rd symbol display apparatus 42 is comprised, for example with the liquid crystal display device, and the display content is controlled by the display control apparatus 45 mentioned later. On the third symbol display device 42, for example, as shown in FIG. 5 described later, three decorative symbol rows L, M, and R on the left, middle, and right are displayed. Each of the decorative symbol rows L, M, R is composed of a plurality of decorative symbols, and these decorative symbols are variably displayed on the third symbol display device 42 so as to be scrolled for each of the decorative symbol rows L, M, R. It has become so. In the present embodiment, the third symbol display device 42 (liquid crystal display device) includes, for example, a large liquid crystal display of 11 inch size. The variable display device unit 35 is provided with a center frame 47 so as to surround the third symbol display device 42. The above-described third symbol display device 42 corresponds to decoration identification information (design) variation display means in the present invention, and the above-described display control device 45 corresponds to display control means in the present invention.

  As shown in FIG. 2, the variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is in an open state in which a game ball is easy to win in the case of a big win and a normal closed state. It is operated repeatedly. As described above, a state in which the variable winning device 32 is repeatedly operated in an open state and a normal closed state in the case of a big win is called a special game state (for example, a big win state). Since the ball enters (wins) and a lot of game balls are paid out for the winning, the game state is advantageous to the player.

  More specifically, when a game ball wins the first start opening 33a, 33b, the two LEDs 40a, 40b of the first symbol display device 40 are displayed in a variable manner, and the display of the LEDs 40a, 40b after the change stop is preset. The special gaming state occurs when the combination of the light emission modes is achieved. For example, in the case of a light emitting mode in which both LEDs 40a and 40b are stopped in a red light emitting state, it indicates that a special gaming state with a probable big hit (specific hit) is won, and both LEDs 40a and 40b are stopped in a blue light emitting state. In the case of the light-emitting mode, it means that the special game state of the big hit (non-specific hit) is normally won, and in the case of the light-emitting mode in which both LEDs 40a and 40b are stopped in the light-emitting states of different colors. (You have lost the special game state).

  The variable winning device 32 is configured such that the large winning opening 32a is in a predetermined open state, and the game ball is likely to win (a big hit state). Specifically, the special winning opening 32a of the variable winning device 32 is repeatedly opened a predetermined number of times (the number of rounds) with the passage of a predetermined time or a predetermined number of winnings in the open state as one round. The number of times that the game ball has passed through the first start ports 33a and 33b is held up to a maximum of 4 times, and the number of times that the game ball is held is lit and displayed by the hold lamp 40c. Note that the hold lamp 40c may be configured such that a hold display is performed on a part of the display screen of the third symbol display device 42.

  Further, as shown in FIG. 2, the game board 30 is provided with a plurality of rails 51 and 52 for guiding the game balls launched from the game ball launching device 38 (see FIG. 3) to the upper part of the game board 30. Thus, the game balls launched in accordance with the turning operation of the game ball launching handle 18 are guided to a predetermined game area 30a through a ball guide passage 49 (to be described later) of the plurality of rails 51 and 52. . The plurality of rails 51 and 52 are long metal strip members made of stainless steel, and are attached to the game board 30 in an inner and outer double. The inner rail 51 is formed in a substantially annular shape except for about 1/4 of the upper side. The outer rail 52 is formed so that a part (mainly the left side) faces the inner rail 51. In such a case, a guide rail is constituted by the inner rail 51 and the outer rail 52, and a ball guide passage 49 is formed by a portion (the left portion toward the left) where the rails 51 and 52 are parallel to each other at a predetermined interval. . The ball guide passage 49 is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened.

  A return ball preventing member 53 is attached to the tip portion of the inner rail 51 (the upper left portion in FIG. 2). This prevents a situation in which the game ball once guided from the ball guide passage 49 between the inner rail 51 and the outer rail 52 to the upper portion of the game board 30 returns to the ball guide passage 49 again. It has become. Further, in a state in which the game board 30 is attached to the inner frame 12, the outer rail 52 is located at a position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 2: a portion corresponding to the tip portion of the outer rail 52). Is configured such that a return rubber (not shown) provided on the inner frame 12 is positioned. Accordingly, a game ball launched at a predetermined momentum or more is bounced by hitting a return rubber (not shown). Since the outer rail 52 is made of a long metal strip made of stainless steel, the flight of the game ball can be made smoother, that is, the frictional resistance of the game ball can be reduced.

  The lower right corner of the game board 30 is a space for sticking a seal (S1 in FIG. 2) such as a certificate (for example, a serial number is written) or a plate. By sticking a sticker such as a certificate (S1 in FIG. 2) to the lower right corner of the game board 30, the game board 30 and the certificate can be uniquely defined.

  Next, the game area 30a of the game board 30 will be described. As shown in FIG. 2, the game area 30 a is partitioned and formed into a substantially vertically long circular shape by inner peripheral portions (inner and outer rails) of the inner rail 51 and the outer rail 52. In particular, in the present embodiment, the game board 30 The game area 30a defined on the board surface is much larger than before. In the present embodiment, the distance between the uppermost point of the outer rail 52 and the lower part of the game board 30 is 445 mm (58 mm longer than the conventional product), and is from the extreme left position of the outer rail 52 to the extreme right position of the inner rail 51. The distance is 435 mm (50 mm longer than the conventional product). The distance from the extreme left position of the inner rail 51 to the extreme right position of the inner rail 51 is 418 mm.

  In the present embodiment, the game area 30a is viewed from the front of the pachinko machine 10, and the area of the guide rail that is a parallel part of the inner and outer rails 51 and 52 is excluded from the area surrounded by the inner rail 51 and the outer rail 52. As an area. Accordingly, when the game area 30 a is referred to, the guide rail portion is not included, and therefore the left limit position toward the game area 30 a is specified by the inner rail 51, not by the outer rail 52. Similarly, the right limit position toward the game area 30 a is specified by the inner rail 51. Further, the lower limit position of the game area 30 a is specified by the lower end position of the game board 30. The upper limit position of the game area 30 a is specified by the outer rail 52.

  Therefore, in the present embodiment, the width (maximum width in the left-right direction) of the game area 30a is 418 mm, and the height (maximum width in the vertical direction) of the game area 30a is 445 mm.

  Although detailed disclosure of the drawings is omitted, game balls are supplied to the game ball launcher 38 one by one from the ball outlet on the front frame set 14 side (the ball outlet leading from the most downstream portion of the upper plate 19). .

It can be adjusted to a state where it is attached to 32 with no gap.

<Procedure for replacement with variable winning device 32 with large back surface protrusion>
Next, a procedure for attaching the board box 263 with the fixture 420 when the variable winning device 32 is replaced with a different model and the back surface protrusion amount becomes large will be described with reference to FIG.

  FIG. 14A is a diagram showing that the rearward protrusion amount is increased by exchanging the variable winning device 32 with a different model, and that the replaced variable winning device 32 cannot be attached as it is. (B) is a figure which shows the attachment state by the attachment tool 420 of the board | substrate box 263 when the back surface protrusion amount becomes large by replacing | exchanging the variable prize-winning apparatus 32 with the thing of another model.

  Originally, as shown in FIG. 12B, the board box 263 was attached to the variable winning device 32 on the back side of the game board 30 without any gap. ) Trying to replace with a different model.

  As shown by a two-dot chain line in FIG. 14 (a), the rearward amount of the variable winning device 32 after replacement is large, so that the variable winning device 32 after replacement cannot be attached as it is.

  Therefore, as shown in FIGS. 7 and 10, the release tool 480 is inserted from the opening (release port) on the front side of the game board of the cylindrical portion 440 to release the restriction by the restriction member 450, and both the L-shaped round bars 431. Is moved in the direction of pulling out the cylinder portion 440 by a necessary amount. That is, the mounting tool 420 is moved in the direction of pulling out until the variable winning device 32 after replacement can be attached.

  In addition, when the game board 30 is removed from the inner frame 12 as described above, the opening (release port) on the front side of the game board of the cylindrical portion 440 becomes accessible. As a premise, the gaming board 30 is removed from the inner frame 12, and the cylinder board 440 is accessible to the front opening (release port) of the gaming board.

  Then, as shown in FIG. 14 (b), the variable winning device 32 after replacement is attached, and both L-shaped until the board box 263 is in contact with the base 32b of the variable winning device 32 after replacement. The round bar 431 is inserted into the tube portion 440 on the tip side.

  As described above, even when the rearward protrusion amount is increased by exchanging the variable winning device 32 with a different model, it is possible to loosen the mounting fixture 420 and adjust the state so that the variable winning device 32 after replacement can be attached. By using this attachment tool 420, the board box 263 can be adjusted to a state where it is attached to the variable winning device 32 on the back side of the game board 30 without any gap.

  As described above, according to the pachinko machine 10 of the present embodiment, the gaming board 30 has the variable winning device 32 disposed at a predetermined position in the game area 30a, and the back side of the variable winning device 32 protrudes from the back surface thereof. A board box 263 that houses a main control board 261a that performs control related to a predetermined game, and a mounting device 420 that attaches the board box 263 to a predetermined position that overlaps the variable prize device 32 on the back surface of the game board 30. The mounting instrument 420 includes a projecting member 430 projecting from the board box 263, a cylinder portion 440 provided in the game board 30 into which the projecting member 430 is inserted, and a direction in which the projecting member 430 is inserted into the cylinder portion 440. And a restriction member 450 that restricts movement in the pulling direction, so that, for example, the variable winning device 32 can be replaced with another model or the like. Therefore, even if the amount of protrusion of the variable prize device 32 on the back of the game board is smaller than that before the replacement, the protrusion member 430 is further inserted into the cylinder portion 440 of the game board 30, The board box 263 can be brought closer to the variable winning device 32 after the replacement, and the gap from the board box 263 to the variable winning device 32 after the replacement becomes smaller as the protruding member 430 is inserted into the cylindrical portion 440, and the board becomes smaller. The board box 263 can be brought into contact with the variable winning device 32 after replacement until there is no gap between the box 263 and the variable winning device 32 after replacement.

  As a result, even when the amount of protrusion on the back side of the game board is reduced by exchanging the variable winning device 32 with another model product, the gap from the board box 263 to the changed variable winning device 32 without using a spacer member. Can be provided.

  In addition, since the mounting device 420 includes a release portion 470 that releases the restriction of the movement of the protruding member 430 in the pulling direction by the restriction member 450, for example, by exchanging the variable winning device 32 to a different model or the like, Even if the amount of protrusion of the variable winning device 32 on the back of the game board is larger than before, the release member 430 is allowed to move in the pulling direction by the release of the release portion 470, and the protrusion member 430 is moved to the game board 30. By pulling out from the cylindrical portion 440, there can be no gap from the board box 263 to the variable winning device 32 after replacement. As a result, even when the amount of protrusion on the back of the game board is increased by exchanging the variable winning device 32 with another model product or the like, the gap from the board box 263 to the replaced variable winning device 32 without using a spacer member. Can be provided.

  The projecting member 430 is an L-shaped round bar 431 projecting from the substrate box 263, and an annular groove 432 formed along the circumferential direction of the L-shaped round bar 431 is a longitudinal direction of the L-shaped round bar 431. The cylinder portion 440 is provided on the game board 30 and the regulating member 450 is formed at a predetermined position on the inner peripheral surface of the cylinder portion 440. The claw portion 441 is engaged with the groove portion 432 of the round bar 431, and the release portion 470 causes the release tool 480 inserted from the opening on the front side of the game board in the cylinder portion 440 to abut the claw portion 441. By releasing the nail | claw part 441 in the direction which remove | deviates from the groove part 432, the restriction | limiting of the movement to the extraction direction of the protrusion member 430 by the control member 450 is cancelled | released. Therefore, in order to cancel the restriction of the movement of the protruding member 430 in the pulling direction, the release tool 480 must be inserted from the opening on the front side of the game board of the cylindrical portion 440. In other words, since it is necessary to make the cylinder part 440 accessible from the front of the game board, it takes much time and is more excellent in anti-fraud measures. Also, the release member 480 inserted from the opening on the front side of the game board in the cylinder portion 440 is brought into contact with the claw portion 441 and the claw portion 441 is released in a direction away from the groove portion 432. Since the restriction | limiting of the movement to the extraction direction of 430 is cancelled | released, the restriction | limiting of the movement to the extraction direction by the control member 450 can be cancelled | released suitably.

  Further, the release tool 480 is a cylindrical member into which the L-shaped round bar 431 can be inserted, and the outer periphery on the tip side is tapered, and the claw portion 441 receives the insertion of the tip of the release tool 480. A reverse tapered portion 452 is provided. Therefore, the release tool 480 is inserted from the opening on the front side of the game board of the cylindrical portion 440, and the L-shaped round bar 431 is inserted into the hollow portion of the release tool 480, so that the release tool 480 is moved toward the restriction member 450. When the tip of the release tool 480 reaches the claw portion 441, it is inserted into the reverse taper portion 452 of the claw portion 441. At the same time, the claw portion 441 can be released in a direction away from the groove portion 432 of the L-shaped round bar 431, and the locking of the L-shaped round bar 431 to the cylindrical portion 440 can be easily released by inserting the release tool 480. .

  Further, the L-shaped round bar 431 is separate from the board box 263, and the tip side can be inserted into the through hole 264 formed in the board box 263, and the other end side cannot be inserted into the through hole 264. Since it has a certain shape, the L-shaped round bar 431 cannot be removed from the board box 263 unless the tip side of the L-shaped round bar 431 is removed from the cylindrical portion 440, and the other end side of the L-shaped round bar 431 can be destroyed, When the round bar 431 is cut, it is possible to find out that there has been a fraudulent act from the traces such as the destruction, and it is possible to reduce the fraud due to unauthorized removal of the L-shaped round bar 431.

  In addition, two through holes 264 are formed at predetermined positions in the board box 263 in a predetermined direction and spaced from each other, and the cylindrical portions 440 are respectively provided in the through holes 264 in the game board 30, and L The round bar 431 is an L-shaped member by bending a predetermined portion from the front end side to the other end side, and the projecting member 430 includes two L-shaped round bars 431. A fastener 460 for fastening the other ends of the L-shaped round bar 431 is provided, and the tip side of each L-shaped round bar 431 is inserted into the two through holes 264 of the board box 263 so as to protrude from the board box 263. The leading end side of each L-shaped round bar 431 is inserted into the cylindrical portion 440 of the game board 30. Therefore, the two tips of the game board 30 are inserted by inserting the two tips of the cono-shaped projecting member 430 in which the two L-shaped round bars 431 are fastened by the fastener 460 into the two through holes 264 of the board box 263, respectively. The board box 263 can be fixed to the game board 30 by being inserted into each of the cylinder parts 440, and the board-shaped protruding member 430 can be inserted into the cylinder part 440 as much as possible to obtain the board. There can be no gap between the box 263 and the game board 30. Further, since the other ends of the two L-shaped round bars 431 constituting the projecting member 430 are held facing each other, it is possible to prevent the substrate box 263 from being opened without permission.

  Moreover, the fastener 460 can release the other ends of the two L-shaped round bars 431, and the two L-shaped round bars 431 released from the fastening by the fastener 460 pass through each other. It can be rotated around the hole 264 and the other end can be directed in the same direction. Therefore, by setting the other end side of the L-shaped round bar 431 in the same direction, the board box 263 can be opened and closed along the L-shaped round bar 431, and the back side of the board box 263 can be opened. Confirmation can be made.

  Further, since the variable winning device 32 includes the pedestal 32b with which the substrate box 263 abuts at a predetermined position on the back side thereof, when the mounting box 420 brings the substrate box 263 closer to the variable winning device 32, the substrate The box 263 comes into contact with the pedestal 32b so that there is no gap, and it is possible to prevent the portion other than the pedestal 32b in the variable winning device 32 from coming into contact with the board box 263 and being damaged.

  The board box 263 accommodates the main control board 261a inside and includes a sealing unit 269. The sealing unit 269 seals the board box 263, and the seal is released when the predetermined portion is destroyed. Is. Therefore, the cheating person wants to take out the main control board 261a from the board box 263 in order to cheat on the main control board 261a, but the board box 263 is sealed by the sealing unit 269, It is difficult to take out the control board 261a, and if the seal is destroyed, an illegal act can be found by finding the destruction trace. In addition, even if the board box 263 is to be removed, the board box 263 is attached to the game board 30 by the mounting device 420, and the protruding member 430 cannot be removed from the cylindrical portion 440. Therefore, the board box 263 is illegally removed from the game board 30. It is difficult to remove it. As a result, the main control board 261a and the board box 263 cannot be removed illegally, and illegal actions can be reduced.
