Description

  The present invention relates to a gaming machine represented by a ball game machine such as a pachinko machine.

  Some gaming machines such as pachinko machines have various control boards for performing control related to games accommodated in a board box. Further, as this substrate box, for example, a box-shaped body is divided into a base portion and a cover portion, and the base portion and the cover portion are fitted and closed together with a control board accommodated therebetween. This is common.

  For example, in a gaming machine disclosed in Patent Document 1 below, a display control device including a display control board assembles a base plate, a window frame, and the like that constitute a base portion and a unit cover that constitutes a cover portion. The unit is integrated (unitized) with the decorative symbol display device. When the assembly structure of the base portion and the cover portion in this configuration is shown, for example, in a simplified manner in FIG. 49, a plurality of engaging claws 901a are formed on the base member 901, and the cover member 902 has a corresponding structure. An engaging hole 902a is formed, and the base member 901 and the cover 902 member are engaged with each other and fixed by engaging the engaging claw 901a with the engaging hole 902a.

JP 2009-6011 A

  However, since the board box tends to increase in size and weight recently, it is difficult to assemble the base part and the cover part in the structure of the board box as described above, which makes the board box assembly work inefficient. It was a factor.

  Therefore, for example, as shown in FIG. 50, an engagement piece 912b whose tip is curved in a substantially arc shape when viewed from the side is formed on one end edge (lower end edge in FIG. 50) of the cover member 912, and corresponds to this engagement piece 912b. Then, an engaging shaft 911b extending along the end edge is formed at one end edge (lower end edge in FIG. 50) of the base member 911, and the engaging piece 912b is engaged with the engaging shaft 911b as indicated by an arrow A11. Engagement claws formed on the other end edge (upper end edge in FIG. 50) of the base member 911 by closing the cover member 912 in a door shape as indicated by an arrow A12 using the shaft support portion as a hinge. By engaging and fixing the base member 911 and the cover 912 member to each other by engaging 911a with an engagement hole (not shown) formed in the other end edge (upper end edge in FIG. 50) of the cover member 912 Configure the box It has also been made.

  According to this configuration, the cover member 912 is assembled so as to be closed like a door in a state where the weight of the cover member 912 is once deposited in the base member 911 at one end edge, that is, in a state where the cover member 912 is supported by the base member 911. Therefore, the base member 911 and the cover member 912 can be easily assembled.

  By the way, when the assembled board box is installed at a predetermined position, it is necessary to easily and surely adjust the position of the board box to the predetermined position. For this reason, for example, as shown in FIG. A positioning boss (projection) 911c is formed on the edge (lower edge in FIG. 50), while a positioning hole (reception hole) 913c is formed in the mounting base 913 to be installed, and the positioning boss 911c is positioned in the positioning hole. It is also possible to perform alignment by inserting it into 913c.

  However, in the configuration as described above, a lot of concavo-convex structures are formed in the substrate box by forming the positioning boss 911c in addition to the engagement claw 911a, the engagement shaft 911b, the engagement piece 912b, etc. The configuration is complicated and takes up a lot of space. In particular, since the concavo-convex structure is easily damaged by an external force, a large number of the uneven structures are easily damaged.

  The present invention has been devised in view of such problems, and an object of the present invention is to provide a gaming machine in which the configuration of the board box is simple, the occupied space is reduced, and the chance of breakage is reduced.

In order to achieve the above object, the gaming machine according to the present invention provides:

The support portion may function as a positioning portion for installing the control device at a predetermined position.

In the present invention, the “board box” implies almost the same contents as the “board case”, and any shape can be used as long as it can accommodate the control board. Includes those that cannot be occluded.
In addition, the support unit that can support one divided component member on the other divided component member is, for example, an engagement piece formed on one divided component member and the engagement piece engaged with each other to be pivotally supported. A support portion configured to have an engagement shaft to be obtained, a convex portion formed on one divided component member, and a concave portion formed on the other divided component member so that the convex portion can be inserted and inserted. Any supporting part or the like that is configured is implied.

  According to the configuration of the present invention, a pair of divided component members out of two or more divided component members constituting the substrate box can be assembled in a state in which one is supported by the other by the support portion. Assembling work can be easily performed. At this time, the support portion can also function as a positioning portion, that is, the support portion functions as a support portion for supporting one divided component member on the other divided component member, and the substrate box at a predetermined position. Since it has a structure that also functions as a positioning part for installation, the structure is simple and the occupied space is also larger than when individual parts specialized for these functions are individually arranged. You can save.

  According to the present invention, the configuration of the substrate box can be simplified, the occupied space can be reduced, and the chance of breakage can be reduced.

(Configuration of front side of pachinko machine)
1 is a front view of the pachinko machine 10, FIG. 2 is a perspective view of the pachinko machine 10, and FIG. 3 is a perspective view of a front frame of the pachinko machine 10. As shown in FIGS. 1 and 2, the pachinko machine 10 includes an outer frame 11 that forms an outer shell of the pachinko machine 10, and an inner frame 12 that is supported on one side of the outer frame 11 so as to be opened and closed. I have. Below, the structure of the outer frame 11 and the inner frame 12 is demonstrated separately.

  The outer frame 11 is formed in a rectangular shape as a whole by a wooden plate material, and each plate material is assembled by a detachable fastener such as a small screw. The outer frame 11 may be made of a light metal such as resin or aluminum. This is because such a configuration can reduce the weight of the pachinko machine.

  On the other hand, the opening / closing axis of the inner frame 12 is set so as to extend vertically on the opposite side (left side of the pachinko machine 10 in FIG. 1) from the position where the handle (game ball launching handle 18 described later) is installed as viewed from the front of the pachinko machine 10. The inner frame 12 can be sufficiently opened to the front side with the opening / closing axis as the axis. If the opening / closing axis of the inner frame 12 is in the vertical direction on the handle installation location side (the right side of the pachinko machine 10 in FIG. 1), the game ball launching handle is opened when the inner frame 12 is opened. This is because the 18 heads and the like interfere with adjacent pachinko machines and card units (ball lending units), and the inner frame 12 cannot be fully opened. The inner frame 12 is made of a synthetic resin, specifically, ABS acrylonitrile-butadiene-styrene resin. By doing so, the advantages of high viscosity and high impact resistance and low cost production are exhibited.

  The inner frame 12 has a lower pan unit 13 at the lowermost portion thereof, and a front frame set 14 that is attached to be openable and closable around a vertical opening / closing axis on the left side of the inner frame 12, and a resin base 25.

The game ball stopped in the lower plate 15 can be discharged to the player's ball storage box (dollar box) through the opening on the bottom surface of the lower plate 15. The game ball launching handle 18 is disposed so as to protrude to the front side on the right side of the lower plate 15. In accordance with the operation of the game ball launching handle 18 by the player, the game ball is driven toward a game board 30 described later by a game ball launching device having a launch solenoid. A sound output port 24 for outputting sound from a speaker is provided at the upper part of the front frame set 14.

  On the other hand, an upper plate 19 as a receiving tray for game balls is provided integrally with the front frame set 14 at a lower portion of the front frame set 14 (above the lower plate 15 described above). The upper plate 19 is a ball tray for temporarily storing the game balls and guiding them to the game ball launching device 38 while aligning them in a row. In addition, an effect button 79 for the player to perform an operation such as changing the background of the decorative symbol display device 42 is provided at the lower left of the upper plate 19.

  In addition, the front frame set 14 is provided with light emitting means such as various lamps in the periphery (for example, corner portion). These light emitting means play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state in the big hit game state or the like. For example, at the periphery of the window portion 101, an annular illumination portion 102 containing a light emitting means such as an LED is provided symmetrically, and lighting or blinking in the big hit gaming state, it is in a big hit gaming state It is the structure which alert | reports.

  In addition, a ball lending operation unit 120 is disposed below the window unit 101, and the ball lending operation unit 120 is provided with a ball lending button, a return button, and a frequency display unit. When the ball lending operation unit 120 is operated with a bill or a card inserted in a card unit (ball lending unit) (not shown) arranged on the side of the pachinko machine 10, a game ball is lent according to the operation. Done. The ball lending button is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is supplied to the upper plate 19 as long as there is a remaining amount on the card or the like. The The return button is operated when requesting the return of a card or the like inserted into the card unit. The frequency display section displays remaining amount information such as a card. Note that the ball lending operation unit 120 is not required for a pachinko machine in which a game ball is directly rented from the ball lending device unit to the upper plate without using a card unit, that is, a so-called cash machine. 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.

  Here, the display contents of the special symbol display device, the normal symbol display device, and the decorative symbol display device 42 will be described. In the pachinko machine 10 of the present embodiment, the special symbol displayed on the special symbol display device as a symbol for showing the player that the jackpot has been generated and the decorative symbol displayed on the decorative symbol display device 42 are two. Types are provided. The decorative symbol is a symbol that changes in synchronization with the special symbol. The decorative symbol starts changing at the same time (or almost at the same time) as the special symbol starts to change, and at the same time (or almost at the same time) as the special symbol changes. To stop the fluctuation. This decorative design is provided in order to provide a player with a variety of display effects so that the player is not bored.

  First, the display contents of the special symbol display device will be described. The special symbol variation display is expressed by a change in the lighting pattern of the nine LED segments. The variation display of the special symbol is started based on winning of the game ball to the start winning device 33, and the variation display of the special symbol is simultaneously stopped after a certain time. After the stop, a lighting pattern indicating a big hit or a lighting pattern indicating a miss is displayed. The number of times that the game ball has won the start winning device 33 is held up to a maximum of four times, and the number of times that the game ball is held is lit and displayed on the hold lamp 800a of the special symbol hold display device 800.

  Next, display contents of the decorative symbol display device 42 will be described. On the display screen of the decorative symbol display device 42, for example, three decorative symbol columns Z1 to Z3 are displayed in three display areas divided into an upper stage, a middle stage, and a lower stage. These decorative symbol rows Z1 to Z3 are scroll-displayed from right to left. The decorative symbol is composed of, for example, a main symbol composed of numbers “1” to “9” and a sub symbol smaller than the main symbol, and a symbol row of the decorative symbol is formed by each of the main symbol and the sub symbol. In each symbol row formed with decorative symbols, the main symbols are arranged in ascending or descending order of numbers, and sub-designs are arranged between the main symbols. When a winning to the start winning device 33, that is, a start winning occurs, the decorative symbol is displayed in a variable manner, and the variable display is stopped after a lapse of a certain time according to the changing pattern. 3 nine decorative symbols are displayed as a display result. In the variable display won in the big win lottery, the display control device 45 controls so that three identical main symbols stop on a vertical or diagonal straight line among the nine decorative symbols, The jackpot is indicated. On the other hand, in the variable display out of the big hit lottery, the display control device 45 controls the game so that three of the nine main symbols do not stop in the vertical or diagonal direction, and the same main symbols are stopped. The occurrence of detachment is shown to the person.

  Next, the display contents of the normal symbol display device will be described. The change display of the normal symbol is expressed by alternately lighting the first lamp (appearance is ◯ shape) and the second lamp (appearance is X shape). The normal symbol variation display is started on the condition that the game ball passes through the second start winning device 34, and the regular symbol variation display stops after a certain period of time. And when it stops by a 1st lamp | ramp, the 1st start prize-winning apparatus 33 is comprised only for predetermined time, and it is comprised so that it may open | release. The number of times that the game ball has passed through the second starting prize-winning device 34 is held up to 4 times, and the number of times that the game ball is held is lit and displayed on the hold lamp 801a of the normal symbol hold display device 801.

  Next, the operation of the pachinko machine 10 configured as described above will be described. In the present embodiment, the MPU 501 in the main control device 261 uses various counter information during the game to set up a jackpot lottery or a symbol display setting of a special symbol display device. Specifically, a counter group related to the special symbol and a counter group related to the normal symbol are provided. First, a counter group related to special symbols will be described. As a group of counters related to special symbols, the jackpot random number counter C1 used for the jackpot lottery, the jackpot symbol counter C2 used for selecting the jackpot symbols of the special symbol display device, and the special symbol display device when the special symbol display device fluctuates. Stop pattern selection counter C3 used for selection of stop patterns (corresponding to reach lottery of reaching or completely losing in the variation of decorative symbols) and initial values used for setting initial values of the jackpot random number counter C1 A random number counter CINI1 and variation type counters CS1 to CS3 for determining a type used for variation pattern selection are provided.

  Here, the variation pattern means each pattern (form) in a case where features having common features of variation display are divided.

  Each of the counters C1 to C3, CINI1, CS1 to CS3 is a loop counter that adds 1 to the previous value every time it is updated, and returns to 0 after reaching the maximum value. Each counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area 700 including one execution area and four holding areas (holding first to fourth areas). Each value of the jackpot random number counter C1, the jackpot symbol counter C2, and the stop pattern selection counter C3 is stored in accordance with the winning timing of the ball.

Next, the specific contents of each counter will be described in detail.
The jackpot random number counter C1 is configured such that, for example, 1 is sequentially added within a range of 0 to 738, and after reaching the maximum value (that is, 738), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI1 at that time is read as the initial value of the jackpot random number counter C1. Note that the random number initial value counter CINI1 is configured as a loop counter that is updated in the same range as the big hit random number counter C1 (value = 0 to 738), and is updated once every timer interruption and within the remaining time of normal processing. Will be updated repeatedly. The jackpot random number counter C1 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball wins the start winning device 33. The number of random number values that are jackpots is set at low probability and high probability, and the number of random numbers that are jackpots at low probability is 2, and the value is “373, 727” There are 14 random numbers that are big hits at high probability, and the values are “59, 109, 163, 211, 263, 317, 367, 421, 479, 523, 577, 631, 683, 733”. is there. High probability means a state in which a special symbol combination is a jackpot due to the combination of a specific symbol that is a predetermined probability variation symbol and the subsequent jackpot probability has increased as added value, so-called probability change. Time (when the probability is low) refers to a case where the probability variation state is not such.

  The jackpot symbol counter C2 determines a symbol at the time of a jackpot when the variation of the special symbol on the special symbol display device is stopped. For example, the jackpot symbol counter C2 is incremented one by one within a range of 0 to 4, and the maximum value (that is, 4). After reaching this value, it returns to 0. For example, when the value of the jackpot symbol counter C2 is “0” or “1”, nine LED segments are stopped at a specific lighting pattern, and the combination of stop symbols in this case is a non-specific symbol (normally Of jackpot symbol).

  When the value of the jackpot symbol counter C2 is “2”, “3”, “4”, the nine LED segments stop in a specific lighting pattern different from the above, and the stop symbol of this case The combination means a specific symbol (probability variation symbol).

  The jackpot symbol counter C2 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball wins the start winning device 33.

  The stop pattern selection counter C3 is, for example, incremented by 1 in the range of 0 to 238, and returns to 0 after reaching the maximum value (that is, 238). In the present embodiment, the special symbol variation display is configured to be expressed by nine LED segments. Therefore, in the case of a special symbol, there is no concept of reach, and a stop pattern corresponding to reach is designated as a stop pattern selection counter C3. It is decided to decide. On the other hand, in the case of a decorative symbol, since three decorative symbols are stopped, there is a reach. Therefore, in the case of a decorative symbol, the reach lottery is determined by the stop pattern selection counter C3. That is, in the case of a decorative design, after the reach has occurred, the final stop symbol is shifted by one shift before and after the reach symbol, and the stop symbol is stopped before and after the reach symbol. It is decided to draw “reach other than front / rear off” that stops and “completely out” that does not generate reach. For example, the stop pattern selection counter C3 = 0 to 201 corresponds to complete detachment, the stop pattern selection counter C3 = 202 to 208 corresponds to anteroposterior detachment reach, and the stop pattern selection counter C3 = 209 to 238 reaches reach other than anteroposterior detachment. Applicable.

  Here, “reach” refers to a combination of symbols that are stopped first after the decorative symbol displayed on the display screen of the decorative symbol display device 42 starts variably displaying (in a decorative symbol having a plurality of effective lines). The combination of jackpot symbols, suggesting to the player that the jackpot will be a big win depending on the display result of the symbols that are the same symbol on any active line) Is a display that makes a player expect the game, and is a type of entertainment production. Interesting effects are the display of a predetermined design represented by reach on the display screen of the decorative design display device 42 during the variable display, the output of a specific sound from a speaker, or the use of a vibration motor. This is an effect that causes the player to expect that the display result after the variation display will be a big hit with the variation display, such as vibrating the game ball launch handle 18.

  The stop pattern selection counter C3 is periodically updated (once every timer interruption in this embodiment) and stored in the reserved ball storage area 700 of the RAM 503 at the timing when the game ball wins the start winning device 33.

The variation type counter CS1 is, for example, incremented by 1 within a range of 0 to 198, and returns to 0 after reaching the maximum value (that is, 198). The variation type counter CS2 is, for example, incremented by 1 within a range of 0 to 240, and returns to 0 after reaching the maximum value (that is, 240). For example, the variation type counter CS3 is incremented by 1 within a range of 0 to 162, for example, and reaches a maximum value (that is, 162) and then returns to 0.
The variation type counter CS1 determines a rough symbol variation mode such as the reach type such as normal reach, super reach, premium reach, etc., and the variation type counter CS2 further refines the symbol such as normal reach A, normal reach B, etc. The variation mode is determined, and the variation type counter CS2 determines, for example, the addition / subtraction of the variation time in the case of a slip stop variation. Therefore, a variety of variation patterns can be easily realized by combining these variation type counters CS1 to CS3.

  The counters CS <b> 1 to CS <b> 3 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of the counters CS1 to CS3 are acquired when determining the variation pattern at the start of variation of the special symbol by the special symbol display device and the decorative symbol display device 42.

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

  The hit random number counter C4 is a loop counter that adds 1 to the previous value every time it is updated, and returns to 0 after reaching the maximum value. The counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area 701 including one execution area and four holding areas (holding first to fourth areas). In each of these areas, the second start winning device 34 is provided. The value of the hit random number counter C4 is stored in accordance with the passing of the game ball.

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

  In addition, the magnitude | size and range of each counter are only examples, and can be changed arbitrarily. However, if importance is attached to irregularity, the big hit random number counter C1, stop pattern selection counter C3, hit random number counter C4, and variation type counters CS1 to CS3 are all different prime numbers and are not synchronized in any case. It is desirable to leave.

The details of each control process executed by the MPU 501 in the main controller 261 will not be described here.
However, in summary, as described above, a winning lottery with a predetermined probability is made in the main control device 261 by winning the start winning device 33, and when winning, it shifts to a special gaming state. Thus, the variable winning device 32 enters a winning ball receiving state.

(Variable winning device and collection unit)
In this embodiment, the variable winning device 32 is configured as follows.
The basic configuration of the variable winning device 32 is to house a winning ball from a large winning opening 61 having a width that allows a plurality of gaming balls to pass in the lateral direction of the game board 30 in a housing portion (not shown). A detection sensor (not shown) is detected from a discharge portion provided in the storage portion.

  Then, a start winning device 33 (33a and 33b: see FIGS. 4 and 5) for entering a game ball flowing down the flowing space between the window portion 101 and the game board 30 into the game area of the game board 30 is provided. A winning lottery with a predetermined probability is performed by the main control device 261 by entering the starting prize winning device 33, and the game state is shifted to the special game state by the corresponding lottery. In the special game state, At least once, the variable winning device 32 is switched from the non-ball receiving state to the ball receiving state, and in the ball receiving state, a predetermined number of winning balls received from the large winning opening 61 are received in the receiving portion by the detection sensor. A predetermined number of award balls are paid out by detecting the above.

An engagement sealing portion 602F into which the stop member 603 can be fitted is formed. The engagement sealing portion 602F is bent in a rectangular shape (the rectangle is bent in a right angle in a bowl shape) so as to straddle the back wall (front wall in FIG. 11) and the upper wall or side wall of the case cover 602. A bridge wall 602C is integrally formed at the rear end portion of the notch and the upper surface portion or the side surface portion so as to communicate with the walls on both sides of the notch portion. Both sides of the bridge wall 602C are narrow to form narrow portions. Inside the engagement sealing portion 602F, a support wall 602S is integrally formed in parallel to the bridging wall 602C at an interval, and a sealing member 603 is inserted between the bridging wall 602C and the support wall 602S. In addition, an engagement piece that can engage with the sealing member 603 is integrally formed on the support wall 602S (not shown). The sealing member 603 is a substantially rectangular shape inserted between the bridge wall 602C and the support wall 602S from a rectangular pressing plate 603P corresponding to the rear surface portion (front surface portion in FIG. 11) of the engagement sealing portion 602F. The plate-shaped insertion piece 603N is a resin member integrally formed so as to extend vertically, and the insertion piece 603N can be engaged with the engagement piece of the support wall 602S. The protrusion is integrally formed (not shown).

  As shown in FIGS. 10 and 11, an engagement hole 602 </ b> E that can engage an engagement piece 601 </ b> E of a base frame 601, which will be described later, is formed at the center of the upper wall of the case cover 602. The engagement hole portion 602E is formed by recessing the upper wall of the case cover 602 in a groove shape inward from the rear end to the center portion, and opening the front end portion at the bottom portion in a slit shape, which will be described later. The claw portion can be engaged from the inside. Engaging mechanism portions 602H that can engage with engaging portions 82E of an outer packet member 82, which will be described later, are disposed near both ends of the upper surface of the case cover 602, respectively. As shown in FIG. 11, the engaging mechanism portion 602H includes a slide member 602H1 having a structure in which a tab piece extending rearward is orthogonal to the central portion of the engaging piece extending in the shape of a square bar in the left-right direction. Is slidably held to the left and right along the front edge of the upper surface of the case cover 602, and on the inner side (center side) adjacent to the slide member 602H1, along the front edge of the upper surface of the case cover 602. A rectangular parallelepiped storage portion 602H2 is integrally formed so that one side portion of the engagement piece of the slide member 602H1 can be moved in and out.

  As shown in FIGS. 12 to 14, curved engagement pieces are respectively provided at two places on the left and right sides of the lower wall of the case cover 602, more specifically, an intermediate portion between the center and the left end and an intermediate portion between the center and the right end. 602R is integrally formed. The curved engagement piece 602R has a shape in which the front end of the lower wall of the case cover 602 extends locally (to a small width) forward and curves downward so as to form an arc shape when viewed from the side.

  As shown in FIG. 12, the base frame 601 is a molded body made of a transparent resin having a laterally substantially rectangular outer shape that matches the outer shape of the case cover 602, and a peripheral wall extends rearward from four sides. The thinned portion on the extended end side is extended inwardly on the way of extension, and the thinned portion on the extended end side fits into the peripheral wall of the case cover 602 from the inside, and the outside of the thickened portion on the proximal end side from the thinned portion. The side surface is flush with the peripheral wall of the case cover 602. Engagement pieces 601E extending backward are integrally formed on the peripheral wall of the base frame 601 at five locations corresponding to the engagement sealing portions 602F and the engagement hole portions 602E of the case cover 602, respectively. The engaging piece 601E extends rearward from the extending end edge of the peripheral wall of the base frame 601 in a rectangular shape, and a claw portion that protrudes outward in a hook shape is formed at the extending end portion. ing. A rectangular display opening 601 </ b> A that is slightly smaller than the outer shape of the base frame 601 is formed on the front surface of the base frame 601. In other words, the base frame 601 is largely open at the front surface by the display opening 601A. In other words, the front edge of the peripheral wall slightly extends inward at right angles to form a saddle shape in cross section, and has four sides. The frame member extends so as to be closed in a rectangular shape along the outer peripheral portion.

  As shown in FIGS. 12 to 14, claw-like protrusions 601 </ b> P are integrally formed on the lower wall of the base frame 601 at two left and right positions corresponding to the curved engagement pieces 602 </ b> R of the case cover 602. . As shown in FIGS. 13 and 25, the claw-like protrusion 601P has a substantially horizontally long rectangular shape in front view from the rear edge of the lower wall of the base frame 601 (front edge in FIG. 13). Projecting downward, the front surface (back surface in FIG. 13) is a vertical surface, and the rear surface (front surface in FIG. 13) is inclined forward and downward from the rear edge of the lower wall of the base frame 601 until it intersects the front surface portion. It has a slope that extends, and has a roughly vertically elongated right-angled triangular cross-sectional shape, and is a protruding structure that extends in the shape of a triangular prism on the left and right. The (tip edge) is also round in cross section, and the corners at both ends are also rounded into a round shape when viewed from the front, making it difficult to stick to other structures.

  A penetration portion 601S that penetrates in the front-rear direction is formed at the base end portion of the claw-like protrusion 601P. As shown in FIG. 13, the penetrating portion 601S penetrates rearward while opening in the form of a horizontally long strip (slit) as shown in FIG. 13, and the front side passes down the claw-like protrusion 601P to the vicinity of the tip as shown in FIG. As shown in FIG. 13, the upper end extends from the lower wall of the base frame 601 to the inside (upward) while maintaining the same width, so that it slightly bites (indents). In addition, the recessed portion extends through the lower wall of the base frame 601 in the front-rear direction. That is, the lower wall of the base frame 601 is recessed in a rectangular shape in front view from the positions on both sides of the claw-like protrusion 601P inward (upward).

  As shown in FIG. 25, the end edge portion constituting the lower edge of the slit-like opening of the penetrating portion 601S in the rear wall of the claw-like projection 601P (front wall in FIG. 13) bulges inward in a substantially circular cross section. An engagement shaft portion 601R that is formed in a shape and extends in the left-right direction is thereby formed. The lower part of the rear wall of the claw-like protrusion 601P extends to the front surface along the thickness direction. Accordingly, the claw-like projections 601P are arranged so as to communicate between the both side wall portions that extend from the lower wall of the base frame 601 in a substantially vertically elongated right triangle shape and the lower end portions (tip portions) of the both side wall portions. , A rear wall portion extending rearward and upward from the rear upper edge of the lower edge portion, and an engagement shaft portion 601R extending right and left along the upper edge of the rear wall portion. In other words, both side surface portions and the lower end portion are completely closed, the portion below the slit-like opening of the through portion 601S in the rear surface portion is closed, and the front portion is large except for the lower end portion. The internal space that is open and is surrounded by the side wall portions, the lower end edge portion, the rear wall portion, and the engaging shaft portion 601R communicates with the front external space through the through portion 601S, and also has a slit shape in the through portion 601S. Backward through opening It has a configuration which communicates with the external space.

  Hereinafter, the assembly procedure of the display control device 45 will be described with reference to FIGS.

  First, a display control board or the like is disposed and fixed inside the case cover 602 (not shown), and the decorative symbol display device 42 is inserted and fixed as shown in FIG. 14 from the front side.

  Next, as indicated by an arrow A1 in FIGS. 12 to 14, both curved engagement pieces 602R of the case cover 602 are engaged with the both claw-shaped projections 601P of the base frame 601 from the rear side. More specifically, as shown in FIGS. 24 and 25, when the base frame 601 is in an upright mounting posture, the case cover 602 is moved downward from the upright mounting posture (about Inclined so that the tip of the curved engagement piece 602R faces forward, and in this position, the curved engagement piece 602R is inserted through the claw-like projection 601P of the base frame 601 as shown in FIGS. It is engaged with the slit-shaped opening of 601S so as to be inserted from the rear side.

  Next, as shown by an arrow A2 in FIGS. 15 to 17, the case cover 602 is rotated to stand up, and is fitted to the base frame 601 and closed as shown in FIGS. At this time, as shown in FIGS. 28 and 29, when the upper end side of the case cover 602 is pulled up, the curved engagement piece 602R of the case cover 602 is engaged with the engagement shaft portion 601R of the claw-like protrusion 601P of the base frame 601. In the state of being engaged so as to be mounted from above, as shown by an arrow A3 in FIG. 29, it slides along the peripheral surface of the engagement shaft portion 601R, whereby the case cover 602 is moved to the engagement shaft. The part 601R is closed so as to rotate in a hinge manner around the rotation axis. At the final stage of the closing operation, the case cover 602 hits the tip of the five engagement pieces 601E in the base frame 601 and gently touches, but when pushed in as it is, as shown in FIGS. 10 and 11, each engagement piece 601E is shown. Is elastically (snappedly) engaged with the front end edges of the engagement sealing portion 602F and the engagement hole portion 602E of the case cover 602, whereby the case cover 602 and the base as shown in FIGS. The frame 601 is fitted and fixed.

  When the case cover 602 is closed until it is sufficiently fitted to the base frame 601 as described above, the curved engagement pieces 602R of the case cover 602 are formed on the claw-like projections 601P of the base frame 601 as shown in FIG. The engaging shaft portion 601R is wound around, and the tip of the engaging shaft portion 601R reaches a position close to the rear wall of the claw-like projection 601P from the inside. Therefore, the curved engagement piece 602R fills most of the internal space of the claw-like projection 601P, which forms a part of the through portion 601S in the claw-like projection 601P. On the other hand, the curved engagement piece 602R itself is housed in the through portion 601S of the claw-like projection 601P as a whole, and the front surface is open, but the other five surfaces are surrounded (covered) by the claw-like projection 601P. A). In other words, the curved engagement piece 602R is completely accommodated inside the claw-like protrusion 601P together with the engagement shaft portion 601R, and the portions other than the front surface portion are closed. Further, at this time, the curved engagement piece 602R is tightly accommodated in the claw-like projection 601P with almost no (substantially) clearance.

  At this stage, each engagement piece 601E can be removed from the engagement sealing portion 602F and the engagement hole portion 602E by being elastically deformed, so that the engagement state can be released. 602 and base frame 601 can be opened or further separated. It should be noted that the relative positional relationship between the case cover 602 and the base frame 601 in the above procedure remains the same, and the case cover 602 is held, for example, in a posture that is flattened with the front face up, and the base frame 601 is You may make it close by hingedly rotating, and according to this, closing operation can be performed more lightly.

  Next, as shown in FIGS. 18 to 20, the sealing members 603 are fitted into the four engagement sealing portions 602 </ b> F of the case cover 602 from the rear. At this time, when the pressing plate 603P of the sealing member 603 is pressed and the insertion piece 603N is inserted between the bridging wall 602C and the supporting wall 602S of the engaging sealing portion 602F, the engaging piece of the supporting wall 602S is inserted. Thus, the engagement protrusion is engaged, and the sealing member 603 can be fitted and fixed to the engagement sealing portion 602F in a one-touch manner. When the sealing member 603 is thus fitted, the insertion piece 603N of the sealing member 603 has a distal end abutting against the distal end of the engagement piece 601E of the base frame 601 from the inside, and an engagement protrusion of the sealing member 603. Is engaged with the engagement piece of the engagement sealing portion 602F, and there is substantially no gap between the bridging wall 602C and the support wall 602S of the engagement sealing portion 602F, and therefore in a stationary state. As a result, the engagement piece 601E of the base frame 601 is prevented from being elastically deformed inward by the insertion piece 603N of the sealing member 603, and is engaged with the engagement sealing portion 602F of the case cover 602. On the other hand, the engagement state between the engagement protrusion of the sealing member 603 and the engagement piece of the engagement sealing portion 602F is difficult to release from the outside. For sealing It is difficult to extract the member 603 from the engaging sealing portion 602F. Therefore, once the sealing member 603 is pushed into the engagement sealing portion 602F, the fixed state can be released unless one of the base frame 601, the case cover 602, and the sealing member 603 is broken. It is possible to achieve a sealed state that is difficult to open without leaving a trace such as breakage or breakage, thereby effectively preventing an unauthorized opening operation.

  In addition, when it is necessary to open the display control device 45 for the purpose of checking the inside after the sealing state is established, the narrowed portion of the bridging wall 602C of the engagement sealing portion 602F is cut with a nipper or the like. If it cuts off by this, the sealing member 603 can be removed from the engagement sealing part 602F, and the case cover 602 and the base frame 601 can be opened. If the sealing member 603 is removed in this way, the engagement sealing portion 602F loses its sealing function. However, in this embodiment, the engagement sealing portion 602F is provided at four locations. If the sealing member 603 is fitted and sealed in two or one place per turn, the sealing and unsealing operations can be repeated a total of two to four times. Since the two or one sealing member 603 used for sealing can be removed without being damaged, it can be reused for the second and subsequent sealing.

  Through the above procedure, the assembly of the display control device 45 is completed as shown in FIGS. 10 and 21 to 23. Next, a procedure for installing the assembled display control device 45 at a predetermined position in the gaming machine will be described with reference to FIGS.

  First, as shown in FIG. 32, the display control device 45 is brought to the outer packaging member 82 from the rear upper side, and the two claw-like projections 601P of the display control device 45 are connected to both the outer packaging member 82 as shown in FIGS. It is inserted into the receiving hole 82P and engaged and supported.

  The outer packaging member 82 is a member that mainly functions as a mounting base (mounting base) on which the display control device 45 or the like is mounted, has a substantially rectangular front shape, and has a mounting flange 82F formed on the periphery thereof. The inside of the flange 82F is a member made of transparent resin having a depth that bulges rearward as a whole, and a position slightly above the lower end on the back surface of the game board 30 (between the big winning opening and the starting winning opening) Are attached and fixed so as to cover almost the entire area from the position of the height to the position near the upper end. A laterally long rectangular central opening 82S that exposes the liquid crystal display screen of the decorative symbol display device 42 is formed in the center of the outer packaging member 82, and display control is performed with a slight gap from the central opening 82S to the outer peripheral side. An outer frame wall 82 </ b> C is formed which can surround the outer periphery of the device 45 and extends rearward in a substantially horizontally long rectangular shape when viewed from the front.

  The receiving hole portions 82P are formed at two locations on the left and right sides of the lower wall of the outer frame wall 82C corresponding to the claw-like projections 601P of the display control device 45, respectively, and as shown in FIG. A substantially rectangular opening 82P1 extending from the base end position to a position slightly inside the extension end and having a slightly wider width than the claw-like projection 601P of the display control device 45 is formed, and from the front end of the opening 82P1 The canopy portion 82P2 is formed from a slightly rear position and bulging upward in a substantially rectangular shape when viewed from the front and extending forward.

  Next, with the display control device 45 supported by the two receiving holes 82P of the outer packaging member 82 by the two claw-shaped projections 601P as described above, the upper end side is moved forward and upward in a hinge-like manner around the support portion at the lower end. As shown in FIGS. 41 to 46, it is inserted into the outer frame wall 82C of the outer packet member 82 as shown in FIGS.

  Thereafter, the upper end portion of the display control device 45 is fixed to the outer packet member 82 by the engagement mechanism portion 602H. As shown in FIG. 37, in the outer package member 82, the left and right two portions corresponding to the both engagement mechanism portions 602H of the display control device 45 are respectively substantially rectangular parallelepiped engagement portions having a configuration in which the central side surface portion is opened. 82E is formed, and with the display control device 45 fitted into the outer frame wall 82C of the outer packaging member 82 as described above, the knob piece of the slide member 602H1 in the engagement mechanism portion 602H of the display control device 45 is removed. The upper end portion of the display control device 45 can be fixed to the outer packaging member 82 by operating and inserting the other side portion of the engagement piece into the engagement portion 82E.

(Function)
As described above, the pachinko machine 10 is configured in such a manner that the display control device 45 configured to house the display control board for performing display control relating to the game in the display control board box 45B is installed on the back side of the game board 30. The display control board box 45B includes two divided components, that is, a base frame 601 as a first component and a case cover 602 as a second component, and a base frame 601 as a pair of these divided components. The case cover 602 is formed with a claw-like projection 601P having an engagement shaft portion 601R for engaging and supporting the curved engagement piece 602R as a support portion that can support one case cover 602 on the other base frame 601. In the state where one case cover 602 is supported by the other base frame 601 with the claw-like projections 601P, The display control board box 45B is assembled by assembling the base frame 601 and the case cover 602, and the claw-like projections 601P as the support portions are arranged at predetermined positions, that is, on the back surface of the game board 30. The outer casing member 82 is configured to function as a positioning portion for installation on the outer frame wall 82C.

  With the above configuration, the base frame 601 and the case cover 602 that are a pair of divided components constituting the display control board box 45B are engaged with the claw-like projections 601P (specifically, the curved engagement pieces 602R) that are the support portions. , With one of the case covers 602 supported by the other base frame 601 with the supporting shaft 601R) to be supported, that is, with the weight of one case cover 602 temporarily assembled in the other base frame 601 Therefore, the assembling work can be easily performed. At this time, the claw-like projection 601P, which is a support portion, can also function as a positioning portion, that is, the claw-like projection 601P functions as a support portion that supports one case cover 602 on the other base frame 601. And a function as a positioning portion for installing the display control device 45 on the outer frame wall 82C of the outer packaging member 82. Therefore, the parts specialized for each of these functions are individually provided. Compared to the arrangement, the configuration is simplified and the occupied space is also reduced. Therefore, a large display space can be secured on the liquid crystal display screen of the decorative symbol display device 42, and the degree of freedom in design is improved. Yes. In addition, the nail-like projection 601P, that is, a structure that functions both as a support portion and a positioning portion in a single part, the number of portions for forming the concavo-convex structure, particularly the protrusion structure, is reduced. Therefore, the number of parts that are easily damaged is reduced.

  Further, the claw-like protrusion 601P that is a support portion includes an engagement shaft portion 601R, and one of the case cover 602 of the base frame 601 and the case cover 602 that is a pair of divided constituent members is connected to the engagement shaft. Since the curved engagement piece 602R that can be rotatably engaged and supported by the portion 601R is formed, the case cover 602 is secured by engaging and supporting the curved engagement piece 602R with the engagement shaft portion 601R. Thus, the engagement shaft portion 601R can be closed so as to rotate in a hinge manner with the rotation shaft as a rotation shaft. Therefore, this closing operation is easy to perform and the operability is good.

  Further, since the claw-like projection 601P as the support portion can accommodate the curved engagement piece 602R together with the engagement shaft portion 601R, the internal space of the claw-like projection 601P is efficiently used. Thus, the curved engagement piece 602R and the engagement shaft portion 601R are protected from external force by the claw-like projections 601P.

  Further, since the curved engagement piece 602R is tightly accommodated in the claw-like projection 601P without substantially leaving a gap, the curved engagement piece 602R or the claw-like projection 601P receives external force. However, it is held in a state where it is difficult to be deformed, so that breakage is effectively prevented and the curved engagement piece 602R is engaged and supported without rattling with the engagement shaft portion 601R.

  In addition, when the case cover 602 is closed, the distal end portion of the curved engagement piece 602R is surrounded (covered) by the claw-shaped protrusion 601P, and in particular, is covered from the rear by the rear wall of the claw-shaped protrusion 601P. Therefore, it is difficult to move the distal end portion of the curved engagement piece 602R to release the engagement state with the engagement shaft portion 601R by, for example, inserting an unauthorized tool from the outside. An unauthorized opening operation at 601P is effectively suppressed. In addition, for example, the claw-like projection 601P has a rigidity required particularly as a positioning portion, as compared with the case where the rear surface portion of the claw-like projection 601P is open and the distal end portion of the curved engagement piece 602R is not covered. It is supposed to be.

  In addition, since both sides of the curved engagement piece 602R are covered from both sides by the both side walls of the claw-like projection 601P in the state where the case cover 602 is closed, it is possible to pry in unauthorized tools from the outside. In addition to being difficult, the curved engagement piece 602R is not detached from the side, and is more securely held in the engaged shaft portion 601R.

  Further, the claw-like protrusion 601P as the support portion is formed on one end edge of the display control board box 45B, that is, the lower wall of the base frame 601, and at least one end edge other than the one end edge in the display control board box 45B. An engagement sealing portion 602F is formed at the upper end edge and both side edge portions of the case cover 602, and the base frame 601 and the case cover 602 can be sealed by the engagement sealing portion 602F. Therefore, an unauthorized opening operation of the display control board box 45B is more effectively suppressed.

  In addition, for example, the support portion may be disposed on the upper end portion or one side portion of the substrate box, and one divided component member may be assembled to the other divided component member from above or from the side. On the other hand, in the configuration of the pachinko machine 10, the claw-like projection 601 </ b> P serving as a support portion is disposed at the lower end portion of the display control board box 45 </ b> B, so that one case cover 602 is placed on the other base frame 601. Assembling can be performed in a mounted state, and therefore, the assembling work is easier to perform. At the same time, a claw-like projection 601P as a positioning portion is also provided at the lower end of the display control board box 45B, so that the assembled display control device 45 is placed at a predetermined position in the gaming machine, that is, outside the outer packaging member 82. Also when installing on the frame wall 82C, the display control device 45 can be assembled in a state of being placed on the outer frame wall 82C, and therefore the installation work of the display control device 45 is easier to perform.

(Modification)
The pachinko machine 10 can be variously modified as listed below, for example.

(1) In the embodiment, the claw-like protrusion 601P including the engagement shaft portion 601R for engaging and supporting the curved engagement piece 602R is formed as a support portion for supporting the case cover 602 on the base frame 601. However, the support portion is other than the one having the engagement piece formed on one of the divided component members and the engagement shaft that can be engaged and supported by the engagement piece. In addition, for example, it is possible to have a convex portion formed on one divided component member and a concave portion formed on the other divided component member so that the convex portion can be fitted and inserted. is there.

  FIG. 48 is a schematic diagram illustrating another example of the support portion. In the example shown in the figure, a substrate box 606 is constituted by a base frame 604 as a first component and a case cover 605 as a second component. A claw-shaped protrusion 605R that protrudes in an integrated manner is integrally formed, and claw-shaped protrusions 604P are integrally formed on the lower wall of the base cover 604 at two locations on the left and right sides corresponding to the protrusion 605R of the case cover 605. Is formed. The claw-like projections 604P of the base frame 604 are formed so as to protrude downward with substantially the same outer shape as that of the claw-like projections 601P in the above embodiment, but inside the claw-like projections 604P, A recess 604R that is recessed downward from the upper surface of the lower wall of the base frame 604 is formed, and the recess 604R has an inner surface shape corresponding to the protrusion 605R of the case cover 605. Note that the structure other than the support portion of the substrate box 606 according to the present modification is substantially the same as that of the above-described embodiment, and therefore illustration and description thereof are omitted.

  In this example, the board box 606 is installed on a mounting base member 607 disposed at a predetermined position of the gaming machine. At this time, the claw-like projections 604P of the base frame 604 serve as positioning portions, and the outer frame of the mounting base member 607 The mounting structure and the procedure thereof are inserted into a receiving hole 607P formed in the wall 607C, and this mounting structure and its procedure are the outer packaging member using the both claw-like projections 601P of the display control device 45 as a positioning part in the embodiment. The structure is basically the same as the case where it is inserted into the both receiving hole portions 82P of 82 and engaged and supported, and therefore, further explanation is omitted here.
