  On the lower surface of the glass door frame 2 is a hitting ball supply tray (upper plate) 3. Under the hitting ball supply tray 3, there are provided a surplus ball receiving tray 4 for storing game balls that cannot be accommodated in the hitting ball supply tray 3, and a hitting operation handle (operation knob) 5 for firing the hitting ball. The game board 6 is detachably attached to the game frame 110 on the back surface of the glass door frame 2. The game board 6 is a structure including a plate-like synthetic resin plate constituting the game board and various components attached to the synthetic resin plate, and the detailed structure thereof will be described later. . In addition, a game area 7 is formed on the front surface of the game board 6 in which a game ball that has been struck can flow down.

  An effect display device 9 composed of a liquid crystal display device (LCD) is provided near the center of the game area 7. In the effect display device 9, variable display (fluctuation) of the effect symbol (decoration symbol) synchronized with the variable display of the first special symbol or the second special symbol is performed. Therefore, the effect display device 9 corresponds to a variable display device that variably displays an effect symbol (decoration symbol) as identification information. The effect display device 9 is controlled by an effect control microcomputer mounted on the effect control board. When the first special symbol display 8a (see FIG. 3) is executing variable display of the first special symbol, the effect control microcomputer executes the effect display on the effect display device 9 along with the variable display. When the variable display of the second special symbol is executed on the second special symbol display 8b (see FIG. 3), the effect display is executed on the effect display device in accordance with the variable display. The situation can be easily understood.

  A first special symbol display (first variable display means) 8a (see FIGS. 12 and 13) for variably displaying a first special symbol as identification information is provided at a lower right position on the game board 6. In this embodiment, the first special symbol display 8a is realized by a simple and small display (for example, 7 segment LED) capable of variably displaying numbers 0 to 9. In other words, the first special symbol display 8a is configured to variably display numbers (or symbols) from 0 to 9. A second special symbol display (second variable display means) 8b (see FIGS. 12 and 13) for variably displaying the second special symbol as identification information is located above the first special symbol display 8a. Is provided. The second special symbol display 8b is realized by a simple and small display (for example, 7 segment LED) capable of variably displaying numbers 0 to 9. That is, the second special symbol display 8b is configured to variably display numbers (or symbols) from 0 to 9.

  In this embodiment, the type of the first special symbol and the type of the second special symbol are the same (for example, both 0 to 9), but the types may be different. The first special symbol display 8a and the second special symbol display 8b each variably display a number (or a two-digit symbol) from 0 to 99 using, for example, two 7-segment LEDs. It may be configured.

  Hereinafter, the first special symbol and the second special symbol may be collectively referred to as a special symbol, and the first special symbol indicator 8a and the second special symbol indicator 8b may be collectively referred to as a special symbol indicator.

  For the variable display of the first special symbol or the second special symbol, the first start condition or the second start condition, which is the variable display execution condition, is satisfied (for example, the game ball has the first start winning opening 13 or the second start winning opening) 14), a variable display start condition (for example, when the number of reserved memories is not 0 and the variable display of the first special symbol and the second special symbol is not executed) When the variable display time (fluctuation time) elapses, a display result (stop symbol) is derived and displayed. Note that winning means that a game ball has entered a predetermined area such as a winning opening. Deriving and displaying the display result is to finally stop and display a symbol (an example of identification information).

  The effect display device 9 is for decoration (effect) during the variable display time of the first special symbol on the first special symbol display 8a and during the variable display time of the second special symbol on the second special symbol display 8b. Display design (also referred to as a decorative design) as a design. The variable display of the first special symbol on the first special symbol display 8a and the variable display of the effect symbol on the effect display device 9 are synchronized. Further, the variable display of the second special symbol on the second special symbol display 8b and the variable display of the effect symbol on the effect display device 9 are synchronized. Synchronous means that the start time and end time of variable display are substantially the same (may be exactly the same) and the variable display period is substantially the same (may be exactly the same). Further, when the jackpot symbol is stopped and displayed on the first special symbol display 8a and when the jackpot symbol is stopped and displayed on the second special symbol display 8b, the effect display device 9 reminds the jackpot The combination of is stopped and displayed.

  A winning device having a first start winning port 13 is provided below the effect display device 9. The game ball won in the first start winning opening 13 is guided to the back of the game board 6 and detected by the first start opening switch 13a.

  A variable winning ball device 15 having a second starting winning port 14 through which a game ball can be won is provided below a winning device having a first starting winning port (first starting port) 13. The game ball that has won the second start winning opening (second start opening) 14 is guided to the back of the game board 6 and detected by the second start opening switch 14a. The variable winning ball device 15 is opened by a solenoid 16. When the variable winning ball device 15 is in the open state, the game ball can be awarded to the second starting winning port 14 (it is easier to start winning), which is advantageous for the player. In the state where the variable winning ball apparatus 15 is in the open state, it is easier for the game ball to win the second start winning opening 14 than the first starting winning opening 13. In addition, in a state where the variable winning ball device 15 is in the closed state, the game ball does not win the second start winning opening 14. In the state where the variable winning ball apparatus 15 is in the closed state, it may be configured that the winning is possible (that is, it is difficult for the gaming ball to win) although it is difficult to win a prize.

  Hereinafter, the first start winning opening 13 and the second start winning opening 14 may be collectively referred to as a start winning opening or a starting opening.

  When the variable winning ball device 15 is controlled to be in the open state, the game ball heading for the variable winning ball device 15 is very likely to win the second start winning port 14. The first start winning opening 13 is provided directly under the effect display device 9, but the interval between the lower end of the effect display device 9 and the first start winning opening 13 is further reduced, or the first start winning opening is set. The winning percentage of the second starting prize opening 14 is such that the nails are densely arranged around 13 or the nail arrangement around the first starting prize opening 13 is difficult to guide the game ball to the first starting prize opening 13. This may be made higher than the winning rate of the first start winning opening 13.

  In the upper part of the second special symbol display 8b, the number of valid winning balls that have entered the first start winning opening 13, that is, the first reserved memory number (the reserved memory is also referred to as the start memory or the start prize memory) is displayed. For example, from a 7-segment LED provided with a special symbol hold memory display unit and a second special symbol hold memory display unit that displays the number of effective winning balls that have entered the second start winning opening 14, that is, the second reserved memory number A special symbol hold memory display 18 is provided. The first special symbol reservation storage display unit increases the number of indicators to be lit by 1 every time there is an effective start winning. Then, each time the variable display on the first special symbol display 8a is started, the number of indicators to be turned on is reduced by one. In addition, the second special symbol reservation storage display unit increases the number of indicators to be lit by 1 every time there is an effective start winning. Then, each time the variable display on the second special symbol display 8b is started, the number of indicators to be turned on is reduced by one.

  Further, the display screen of the effect display device 9 is provided with a first reserved memory display unit 18c for displaying the first reserved memory number and a second reserved memory display unit 18d for displaying the second reserved memory number. . In addition, you may make it provide the area | region (sum total pending | holding memory display part) which displays the total number (sum total pending memory count) which is the sum total of the 1st pending memory count and the 2nd pending memory count. As described above, if the summation pending storage display section for displaying the total number is provided, it is possible to easily grasp the total number of execution conditions that are not satisfied with the variable display start condition.

  In this embodiment, as shown in FIG. 1, there is provided a variable winning ball device 15 that opens and closes only the second starting winning opening 14, but the first starting winning opening 13 and the second starting winning opening 13 are provided. Any of the winning openings 14 may be provided with a variable winning ball apparatus that opens and closes.

  Further, as shown in FIG. 1, a special variable winning ball device 20 is provided below the variable winning ball device 15. The special variable winning ball apparatus 20 includes an opening / closing plate, and when the specific display result (big hit symbol) is derived and displayed on the first special symbol display 8a, and the specific display result (big hit symbol) on the second special symbol display 8b. When the open / close plate is controlled to be open by the solenoid 21 in the specific game state (big hit game state) that occurs when the symbol is derived and displayed, the big winning opening serving as the winning area is opened. The game ball that has won the big winning opening is detected by the count switch 23.

  A normal symbol display 10 (see FIGS. 12 and 13) is provided on the right side of the first special symbol display 8a. The normal symbol display 10 is composed of, for example, two lamps. When the game ball passes through the gate 32 and is detected by the gate switch 32a, variable display of the normal symbol display 10 is started. In this embodiment, variable display is performed by alternately lighting the upper and lower lamps (the symbols can be visually recognized when turned on). For example, if the lower lamp is turned on at the end of the variable display, it is a hit. When the lamp on the lower side of the normal symbol display 10 is turned on and it is a win, the variable winning ball device 15 is opened for a predetermined number of times. That is, the state of the variable winning ball device 15 is a state that is advantageous from a disadvantageous state for the player when the lower lamp is turned on (a state in which a game ball can win a prize at the second start winning opening 14). ). On the upper part of the special symbol storage memory display 18, a normal symbol storage memory display 41 (FIG. 4) having four display portions (for example, four segments of seven segment LEDs) for displaying the number of winning balls that have passed through the gate 32. 12, see FIG. 13). Each time there is a game ball passing through the gate 32, that is, every time a game ball is detected by the gate switch 32a, the normal symbol storage memory display 41 increases the number of display units to be turned on by one. Then, each time the variable display of the normal symbol display 10 is started, the number of display units that are lit is reduced by one.

  In addition, the normal symbol storage memory display 41 composed of 7-segment LEDs has four display units (segments) for displaying the number of winning balls that have passed through the gate 32 and, for example, the number of times the special variable winning ball device 20 is opened at a big hit. There are two display units (segments) that indicate (the number of big hits) and two display units (segments) that indicate the gaming state, but these display units are separate from the normal symbol hold storage display unit. You may comprise. Further, the normal symbol display 10 may be configured by a segment LED or the like that can variably display a plurality of types of identification information (for example, “◯” and “x”) called normal symbols.

  Furthermore, in the probability variation state in which the probability of being determined to be a big hit compared to the normal state is high, the probability that the lamp on the lower side of the normal symbol display 10 is turned on is increased and a variable prize is awarded. The opening time of the ball device 15 is lengthened and the number of times of opening is increased. That is, the game ball is controlled to be in a high base state that is controlled so as to make it easier for the game ball to start and win (that is, the variable display execution conditions in the special symbol indicators 8a and 8b and the effect display device 9 are easily established). Transition. Further, in this embodiment, even in the short time state (the game state in which the special symbol variable display time is shortened), the opening time of the variable winning ball device 15 becomes longer and the number of times of opening is increased.

  Note that by extending the time during which the variable winning ball device 15 is in the open state (also referred to as the open extended state), it becomes easier for the game ball to enter the start winning opening (that is, the special symbol indicators 8a and 8b and the effect display). It is also possible to shift to a high base state that is a gaming state controlled so that the variable display execution condition in the device 9 is easily established.

  Further, instead of extending the time during which the variable winning ball device 15 is in the open state, the lower lamp in the normal symbol display 10 is turned on to shift to the normal symbol probability changing state in which the probability of winning is increased. You may move to a high base state. When the lower lamp in the normal symbol display 10 is turned on and hits, the variable winning ball device 15 is opened for a predetermined number of times. In this case, by performing the transition control to the normal symbol probability changing state, the probability that the lower lamp in the normal symbol display 10 is turned on and hits is increased, and the frequency that the variable winning ball apparatus 15 is opened is increased. Therefore, if the normal symbol probability changing state is entered, the opening time and the number of opening times of the variable winning ball device 15 are increased, and a state where it is easy to start a winning (high base state) is achieved. In other words, the opening time and the number of times of opening of the variable winning ball device 15 are increased when the lower lamp is turned on, or when the special symbol stop symbol is a probable symbol, which is disadvantageous for the player. To an advantageous state (a state where it is easy to win a start). It should be noted that increasing the number of times of opening is a concept including changing from a closed state to an open state.

  Moreover, you may transfer to a high base state by shifting to the normal symbol time short state where the fluctuation time (variable display period) of the normal symbol in the normal symbol display 10 is shortened. In the normal symbol short-time state, the variation time of the normal symbol is shortened, so that the frequency of starting the variation of the normal symbol increases, and as a result, the frequency of hitting the normal symbol increases. Therefore, when the frequency that the normal symbol is won increases, the frequency that the variable winning ball apparatus 15 is opened is increased, and the start winning state is easily set (high base state).

  Also, by shifting to the short time state when the variation time (variable display period) of special symbols and production symbols is shortened, the variation time of special symbols and production symbols is shortened, so that effective start winnings are likely to occur. The possibility that a big hit game is played increases.

  Furthermore, by making transitions to all the states shown above (open extended state, normal symbol probability change state, normal symbol short time state, and special symbol short time state), it will be easier to win a start (shift to a high base state). May be. In addition, it is easier to win a start (high base) by shifting to any one of the above states (open extended state, normal symbol probability changing state, normal symbol short time state, and special symbol short time state). Transition to a state).

  On the left and right sides of the game area 7 of the game board 6, there are provided decorative LEDs 25 that are displayed blinking during the game, and at the lower part there is an outlet 26 for taking in a hit ball that has not won. In addition, two speakers 27R and 27L that utter sound effects and sounds as predetermined sound outputs are provided on the left and right upper portions outside the game area 7. A top frame LED 28a, a left frame LED 28b, and a right frame LED 28c provided on the front frame are provided on the outer periphery upper portion, the outer periphery left portion, and the outer periphery right portion of the game area 7. Also, a prize ball LED 51 that is turned on when there is a remaining number of prize balls is provided in the vicinity of the left frame LED 28b, and a ball cut LED 52 that is turned on when the supply ball is cut is provided in the vicinity of the right frame LED 28c. . The top frame LED 28a, the left frame LED 28b, the right frame LED 28c, and the decoration LED 25 are examples of effects light emitters provided in the pachinko gaming machine 1. In addition to the above-described various LEDs for production (decoration), LEDs and lamps for production are installed.

  In addition, an operation unit 50 as an operation means that can be operated by the player is provided on a member constituting the hit ball supply tray 3. An LED 50b that can be turned on and an operation switch 50a for detecting a pressing operation of the operation unit 50 are provided inside the operation unit 50 (see FIG. 3).

  In the gaming machine, a ball striking device (not shown) that drives a driving motor in response to a player operating the batting operation handle 5 and uses the rotational force of the driving motor to launch a gaming ball to the gaming area 7. ) Is provided.

  FIG. 3 is a block diagram showing an example of the circuit configuration of the main board (game control board) 31. FIG. 3 also shows a payout control board 37, an effect control board 80, and the like. A game control microcomputer (corresponding to game control means) 560 for controlling the pachinko gaming machine 1 according to a program is mounted on the main board 31. The game control microcomputer 156 includes a ROM 54 for storing a game control (game progress control) program and the like, a RAM 55 as storage means used as a work memory, a CPU 56 for performing control operations in accordance with the program, and an I / O port unit 57. including. In this embodiment, the ROM 54 and the RAM 55 are built in the game control microcomputer 156. That is, the game control microcomputer 156 is a one-chip microcomputer. The one-chip microcomputer only needs to incorporate at least the CPU 56 and the RAM 55, and the ROM 54 may be external or built-in. The I / O port unit 57 may be externally attached. The game control microcomputer 156 further includes a random number circuit 53 that generates hardware random numbers (random numbers generated by the hardware circuit).

  In the game control microcomputer 156, the CPU 56 executes control in accordance with a program stored in the ROM 54. Therefore, the game control microcomputer 156 (or CPU 56) executes (or performs processing) hereinafter. Specifically, the CPU 56 executes control according to a program. The same applies to microcomputers mounted on substrates other than the main substrate 31.

  The random number circuit 53 is a hardware circuit that is used to generate a random number for determination for determining whether or not to win a jackpot based on a display result of variable symbol special display. The random number circuit 53 updates numerical data in accordance with a set update rule within a numerical range in which an initial value (for example, 0) and an upper limit value (for example, 65535) are set, and starts at a random timing Based on the fact that the winning time is the reading (extraction) of the numerical data, it has a random number generation function in which the numerical data to be read becomes a random value.

  The random number circuit 53 has a numeric data update range selection / setting function (initial value selection / setting function and upper limit selection / setting function), numeric data update rule selection / setting function, and numeric data update rule selection. It has various functions such as a switching function. With such a function, the randomness of the generated random numbers can be improved.

  Further, the game control microcomputer 156 has a function of setting an initial value of numerical data updated by the random number circuit 53. For example, a predetermined calculation is performed using an ID number of the game control microcomputer 156 stored in a predetermined storage area such as the ROM 54 (an ID number assigned with a different value for each product of the game control microcomputer 156). The numerical data obtained by the execution is set as the initial value of the numerical data updated by the random number circuit 53. By performing such processing, the randomness of the random number generated by the random number circuit 53 can be further improved.

  The game control microcomputer 156 reads the numerical data as random R from the random number circuit 53 when a start winning to the first start port switch 13a or the second start port switch 14a occurs, and starts to change the special symbol and the effect symbol Sometimes it is determined whether or not to make a big hit display result as a specific display result based on the random R, that is, whether or not to make a big hit. Then, when it is determined to be a big hit, the gaming state is shifted to a big hit gaming state as a specific gaming state advantageous to the player.

  The RAM 55 is a backup RAM as a non-volatile storage means, part or all of which is backed up by a backup power supply created on the power supply board. That is, even if the power supply to the gaming machine is stopped, a part or all of the contents of the RAM 55 is stored for a predetermined period (until the capacitor as the backup power supply is discharged and the backup power supply cannot be supplied). In particular, at least data corresponding to the game state, that is, the control state of the game control means (the value of the special symbol process flag or the total pending storage number counter) and the data indicating the number of unpaid winning balls are stored in the backup RAM. The data corresponding to the control state of the game control means is data necessary for restoring the control state before the occurrence of a power failure or the like based on the data when the power is restored after a power failure or the like occurs. Further, data corresponding to the control state and data indicating the number of unpaid prize balls are defined as data indicating the progress state of the game. In this embodiment, it is assumed that the entire RAM 55 is backed up.

  A reset signal (not shown) from the power supply board is input to the reset terminal of the game control microcomputer 156. A reset circuit for generating a reset signal supplied to the game control microcomputer 156 and the like is mounted on the power supply board. When the reset signal becomes high level, the game control microcomputer 156 and the like are in an operable state, and when the reset signal becomes low level, the game control microcomputer 156 and the like become inactive. Therefore, an allowable signal that allows the operation of the game control microcomputer 156 or the like is output during a period in which the reset signal is at a high level, and a game control microcomputer in which the reset signal is at a low level. An operation stop signal for stopping the operation of 156 or the like is output. Note that the reset circuit may be mounted on each electric component control board (a board on which a microcomputer for controlling the electric parts is mounted).

  Further, a power-off signal indicating that the power supply voltage from the power supply board has dropped below a predetermined value is input to the input port of the game control microcomputer 156. That is, the power supply board monitors the voltage value of a predetermined voltage (for example, DC30V or DC5V) used in the gaming machine, and when the voltage value decreases to a predetermined value (the power supply voltage is reduced). A power supply monitoring circuit that outputs a power-off signal indicating that). A clear signal (not shown) indicating that a clear switch for instructing to clear the contents of the RAM is operated is input to the input port of the game control microcomputer 156.

  Further, an input driver circuit 58 for supplying detection signals from the gate switch 32a, the first start port switch 13a, the second start port switch 14a and the count switch 23 to the game control microcomputer 156 is also mounted on the main board 31. The main board also includes an output circuit 59 for driving the solenoid 16 for opening and closing the variable winning ball apparatus 15 and the solenoid 21 for opening and closing the special variable winning ball apparatus 20 that forms a big winning opening in accordance with a command from the game control microcomputer 156. 31. Further, an information output circuit (not shown) for outputting an information output signal such as jackpot information indicating the occurrence of a jackpot gaming state to an external device such as a hall computer is also mounted on the main board 31.

  In this embodiment, the effect control means (configured by the effect control microcomputer) mounted on the effect control board 80 instructs the effect contents from the game control microcomputer 156 via the relay board 77. The control command is received, and display control with the effect display device 9 that variably displays the effect symbol is performed.

  The effect control board 80 is equipped with an effect control microcomputer (not shown) including an effect control CPU and a RAM. The RAM may be externally attached. In the effect control board 80, an effect control CPU (not shown) operates according to a program stored in a built-in or external ROM (not shown), and receives from the main board 31 inputted via the relay board 77. An effect control command is received via the input driver and the input port in response to the embedded signal (effect control INT signal). Further, the effect control CPU (not shown) causes the VDP (video display processor) to perform display control of the effect display device 9 based on the effect control command.

  An effect control CPU (not shown) reads necessary data from a character ROM (not shown) in accordance with the received effect control command. The character ROM is for storing character image data displayed on the effect display device 9, specifically, a person, characters, figures, symbols, etc. (including effect symbols) in advance. An effect control CPU (not shown) outputs the data read from the character ROM to the VDP. The VDP performs display control based on data input from the CPU for effect control.

  The effect control command and the effect control INT signal are first input to the input driver on the effect control board 80. The input driver allows the signal input from the relay board 77 to pass only in the direction toward the inside of the effect control board 80 (does not pass the signal in the direction from the inside of the effect control board 80 to the relay board 77). It is also a unidirectional circuit as a means.

  As a signal direction regulating means, the signal inputted from the main board 31 is allowed to pass through the relay board 77 only in the direction toward the effect control board 80 (the signal is not passed in the direction from the effect control board 80 to the relay board 77). A unidirectional circuit (not shown) is mounted. For example, a diode or a transistor is used as the unidirectional circuit. Furthermore, since the production control command and the production control INT signal are output from the main board 31 via the I / O port unit which is a unidirectional circuit, the signal going from the relay board 77 to the inside of the main board 31 is restricted. . That is, the signal from the relay board 77 does not enter the inside of the main board 31 (the game control microcomputer 156 side).

  Further, the effect control CPU (not shown) outputs a signal for driving the LED to the lamp driver board 35 via an output port (not shown). In addition, the effect control CPU outputs sound number data to the audio output board 70 via the output port.

  In the lamp driver board 35, a signal for driving the LED is input to the LED driver via an input driver (not shown). The LED driver supplies a drive signal to each LED provided on the frame side such as the top frame LED 28a, the left frame LED 28b, and the right frame LED 28c. Further, a drive signal is supplied to the decoration LED 25 provided on the game board side. When a light emitter other than the LED is provided, a drive circuit (driver) for driving the light emitter is mounted on the lamp driver substrate 35.

  In the voice output board 70, the sound number data is input to a voice synthesis IC (not shown) via an input driver (not shown). The voice synthesizing IC generates voice and sound effects corresponding to the sound number data and outputs them to an amplifier circuit (not shown). The amplifier circuit outputs to the speakers 27R and 27L an audio signal obtained by amplifying the output level of the speech synthesis IC to a level corresponding to the volume set by the volume. Control data corresponding to sound number data is stored in a sound data ROM (not shown). The control data corresponding to the sound number data is a collection of data showing the output form of the sound effect or sound in a time series in a predetermined period (for example, the changing period of the effect design).

  The effect control CPU (not shown) is connected to the operation unit 50 via an input / output port, and outputs a signal for driving the LED 50b in the operation unit 50 via the input / output port. An operation signal output in response to a player's pressing operation is input from the operation switch 50a in the unit 50.

  That is, the spacer member 250 has a thickness width dimension P2 (see FIG. 11) of about 1 cm, and the mounting surface of the board plate 200 is configured by the front surface 250a formed by the circular ribs 254 and the front end surfaces of the ribs 255. The game board 6 having a thickness width of about 2 cm is constituted by the board surface plate 200 arranged on the front surface 250a.

  In the vicinity of the four corners of the side wall 253, elastic locking claws 270a to 270d elastically locked to locking step portions 220a to 220d formed on the side peripheral surface of the board surface plate 200 cut the kerf from the front end portion. It is formed by.

  As shown in FIGS. 7 and 8, the mounting bosses 260 a to 260 h and 260 j and the positioning bosses 261 a to 261 c described above are provided on the front side of the back plate 252 from the crossing position of the ribs 255 to the front side. Projected toward. The mounting bosses 260a to 260h and 260j and the positioning bosses 261a to 261c have a length that slightly protrudes from the front end of the side wall 253 to the front side. Particularly, the mounting bosses 260c and 260f are formed slightly longer than the other mounting bosses 260a, 260b, 260d to 260h, and 260j and the positioning bosses 261a to 261c, and are assembled as described later. The face plate 200 protrudes to the front side from the game board surface 200a, and a screw hole 260k is formed penetrating in the vertical direction.

  When the board surface plate 200 is arranged on the front surface 250a of the spacer member 250 configured as described above, the positioning bosses 261a to 261c are fitted into the positioning holes 208a to 208c formed in the board surface plate 200 from the back side, and the spacer Assembling positions of the panel board 200 with respect to the member 250 are determined, and mounting bosses 260a to 260h and 260j are inserted into the insertion holes 207a to 207h and 207j, respectively, and formed at the tips of the insertion holes 207a to 207h and 207j. The screw hole thus made faces the game board surface 200a side of the board board 200.

  Further, when the back surface 200b of the board surface plate 200 is brought into contact with the front surface 250a of the spacer member 250, the elastic locking claws 270a to 270d are elastically locked to the locking step portions 220a to 220d, and the spacer member 250. The detachment of the board plate 200 from the board is regulated. Thus, in a state where the elastic locking claws 270a to 270d are elastically locked to the locking step portions 220a to 220d, the tips of the elastic locking claws 270a to 270d are the game board surface 200a of the board plate 200. It does not protrude further to the front side (see FIG. 19).

  FIG. 19 shows a state in which the elastic locking claw 270a is engaged with the locking step 220a. The elastic locking claws 270b to 270d and the locking step portions 220b to 220d are configured in the same manner as the elastic locking claws 270a and the locking step portions 220a, and thus detailed description thereof is omitted. And

  Since the length dimension P10 from the base portion to the distal end portion of the elastic locking claw 270a is formed shorter than the thickness width dimension P1 of the board surface plate 200 (P10 <P1), the elastic engagement claw portion 220a is elastically engaged. In a state where the pawl 270a is locked, the distal end portion of the elastic locking pawl 270a is disposed at a position retracted from the game board surface 200a to the back side by a predetermined width dimension P11. Therefore, the tip of the elastic locking claw 270a does not protrude to the front side of the game board surface 200a of the board board 200.

  Further, the length dimension P12 of the locking piece portion of the elastic locking claw 270a is formed to be approximately the same as the width dimension from the rear side edge to the locking step portion 220a on the side surface of the board surface plate 200. The length dimension P13 of the part is formed shorter than the length dimension (P12 + P13) of the locking step part 220a. That is, since the elastic locking claw 270a is locked to the locking step portion 220a when the back surface 200b of the panel surface plate 200 is brought into contact with the front surface 250a of the spacer member 250, the panel surface plate 200 is in the locked state. Against the back and forth.

  As described above, the front end portion of the side wall 253 including the elastic locking claws 270a to 270d is formed so as not to protrude to the front side from the game board surface 200a of the assembled board board 200. Projecting to the front side of the game board surface 200a, the elastic locking claws 270a to 270d are prevented from being damaged due to contact with the floor surface or other game boards 6 or the like during manufacturing, storage, or transportation described later. The

  Further, by disposing the board surface plate 200 on the front surface 250a, the elastic locking claw 270a is locked to the locking step portion 220a and the separation of the board surface plate 200 from the front surface 250a is prevented. Easy to install. Further, the elastic latching claw 270a is not only latched on the side surface of the board surface plate 200 which does not affect the game area 7 formed on the game board surface 200a, but the tip of the elastic latching claw 270a is in the game board surface in the latched state. Since it does not protrude from 200a, when the plurality of game boards 6 are stacked, it is prevented that the tips of the elastic locking claws 270a come into contact with the upper game board 6 and are damaged.

  The positioning bosses 261a to 261c fitted in the positioning holes 208a to 208c and the mounting bosses 260a, 260b, 260d to 260h, 260j inserted into the insertion holes 207a to 207h, 207j Although it does not protrude to the front side from the game board surface 200a of 200, the mounting bosses 260c and 260f protrude to the front side by about 5 mm from the game board surface 200a of the board plate 200.

  Specifically, as shown in FIG. 11, the length dimension P3 of the mounting bosses 260c and 260f protruding from the front surface 250a of the spacer member 250 is longer than the thickness width dimension P1 of the board surface plate 200. Further, the protruding length dimension P4 of the board surface board 200 from the game board surface 200a is longer than the depth dimension P5 of the fitting recesses 264c and 264f (P4> P5).

  As shown in FIG. 9, an out opening 262 communicating with the out port hole 204 is formed in the lower portion of the opening 251 in the back plate 252. Out-out ribs 263 (see FIGS. 6 and 7) are also erected on the periphery of the out-opening 262 on the front side of the back plate 252, and the front end surface thereof is on the periphery of the out-opening hole 204 in the back surface 200 b 200 b of the panel board 200. Thus, an out opening 262 having a predetermined width dimension in the front-rear direction is configured.

  Circular fitting recesses 264c having inner diameters (sizes) into which the tips of the mounting bosses 260c and 260f can be fitted, respectively, at positions corresponding to the mounting bosses 260c and 260f on the back surface 250b of the back plate 252. 264f (see enlarged view in FIG. 11) is recessed, and when a plurality of game boards 6 are stacked in the vertical direction as shown in FIG. 11, the mounting bosses 260c and 260f of the lower game board 6 are fitted. The mating recesses 264c and 264f are fitted. That is, the inner diameter L7 of the fitting recesses 264c and 264f is formed larger than the outer diameter L6 of the mounting bosses 260c and 260f (see the enlarged view in FIG. 11).

  Circular cover body positioning holes 265a to 265d into which the positioning bosses 312a to 312d provided on the cover body 302 can be fitted are formed on the upper left and right sides and the lower left and right sides of the opening 251 in the back plate 252. Is formed. Specifically, a cover body positioning hole 265a is provided at a position corresponding to the positioning boss 312a on the back plate 252, and a cover body positioning hole 265b is provided at a position corresponding to the positioning boss 312b. A cover body positioning hole 265c is provided at a corresponding position, and a cover body positioning hole 265d is provided at a position corresponding to the positioning boss 312d.

  Of these cover body positioning holes 265a to 265d, the inner diameters L1 of the upper right and lower right cover body positioning holes 265a and 265d when viewed from the back side are the upper left and lower left cover body positioning holes 265b when viewed from the back side. , 265c is larger than the inner diameter L2 (L1> L2), and is disposed closer to the upper and lower side walls 253.

  Further, from the cover body positioning holes 265a to 265d, guide concave grooves 266a to 266d (see FIGS. 31 and 32) extending to the periphery of the opening 254 are recessed in the vertical direction. These guide grooves 266a to 266d are formed so as to gradually widen from the cover body positioning holes 265a to 265d toward the periphery of the opening 254, and the positioning bosses are formed at the wide portions of the guide grooves 266a to 266d. After the tips of 312a to 312d are placed, the tips of the positioning bosses 312a to 312d are slid toward the cover body positioning holes 265a to 265d, so that they can be easily fitted into the cover body positioning holes 265a to 265d. It is like that.

  In addition, an arc-shaped engagement step portion 267 that engages with the tips of the ribs of the outer rail decorations 600a to 600c, which will be described later, is provided at the periphery of the opening 251 on the back surface 250b of the back plate 252. It is extended along. The engagement step portion 267 is suspended from the contact surface 267a formed in a C shape in the back view along the periphery of the opening 251 on the back surface 250b of the spacer member 250 and the outer periphery of the contact surface 267a. And a restriction surface 267b to be formed (see FIG. 30). The engagement step portion 267 does not have a part on the right side at the periphery of the opening 251 when the spacer member 250 is viewed from the back side, and is formed in a substantially C shape when viewed from the back side. Good. Furthermore, it does not necessarily have to be formed in an annular shape, but is preferably formed in at least three places on the periphery of the C-shape or the opening 251 in the rear view. The horizontal movement of 604 can be restricted.

  Here, the manufacturing process of the game board 6 configured as described above will be briefly described. After a resin melted by applying heat to a synthetic resin is poured into a mold to form an original board of the board face plate 200, a predetermined process is performed. The original plate is cut into a predetermined shape using an apparatus. On the other hand, the spacer member 250 is molded, and the board face plate 200 and the spacer member 250 are integrally assembled to constitute the game board 6.

  Next, after setting up obstruction nails K (see FIG. 30) and various winning devices etc. on the surface of the board plate 200, the nails K are transported to the nailing machine and placed. These processes are sequentially performed when, for example, the game board is placed on the transport conveyor and transported. And when transporting to a nailing machine through a processing machine such as a mounting hole, in order to save space when waiting in the next processing process, multiple body plates are stacked and efficiently transported to the conveyor Transport.

  In addition, after attaching a ball rail or a small winning device to be described later after nailing, large components such as a large winning device and a control circuit board are attached, but the assembly process is complicated and the assembly speed is increased. Therefore, the game board may be stacked and waited after the nailing and the small winning device is attached.

  As described above, when the game board 6 is transferred to the nailing machine through a processing machine such as a mounting hole, a plurality of main body plates are arranged so as not to take up space when waiting in the next processing process. There is a case where they are transported in a stacked state or wait in a stacked state (see FIG. 10).

  As shown in FIG. 10, the game board 6 can be stacked in the vertical direction in a state where the obstacle nail K, various winning devices, etc. are not attached to the game board surface 200 a of the board board 200. When the game boards 6 are stacked in this way, the front surface of one game board 6 and the back surface of another game board 6 stacked above the same contact each other, but the board surface plate 200 and the spacer member 250 are made of a synthetic resin material. Therefore, the game board 6 loaded above is easy to slide down.

  However, as shown in FIG. 11, the length dimension P3 of the mounting bosses 260c and 260f protruding from the front surface 250a of the spacer member 250 is longer than the thickness width dimension P1 of the board surface plate 200. The tips of the mounting bosses 260c and 260f protruding from the game board surface 200a of the board board 200 of the lower game board 6 are fitted into the fitting recesses 264c and 264f formed on the back surface 250b of the spacer member 250 of the upper game board 6. As a result, the skidding of the upper gaming board 6 relative to the lower gaming board 6 is restricted and sliding is prevented, and the loading position is determined. Therefore, as shown in FIG. Can be stacked.

  Further, when the board surface plate 200 is attached to the front surface 250a of the spacer member 250, the mounting bosses 260c and 260f for restricting the skidding of the upper game board 6 are inserted into the insertion holes 207c and 207f, and the board surface plate 200 with respect to the front surface 250a. Since the mounting position is determined, it is possible to prevent displacement of the board surface plate 200 in the surface direction with respect to the front surface 250a.

  In this embodiment, the fitting recesses 264c and 264f having a size that allows the mounting bosses 260c and 260f to be fitted are recessed in the back surface 250b of the spacer member 250. A fitting recess may be formed by the hole formed in 252 and the back surface 200 b of the panel board 200.

  Moreover, the protrusion length dimension P4 from the game board surface 200a of the board surface board 200 is longer than the depth dimension P5 of the fitting recesses 264c and 264f (P4> P5), so that the lower game board 6 In the state where the front ends of the mounting bosses 260 c and 260 f protruding from the game board surface 200 a of the board board 200 are fitted into the fitting recesses 264 c and 264 f formed on the back surface 250 b of the spacer member 250 of the upper game board 6. A gap P6 having a predetermined width (for example, about 1 to 3 mm) is formed between the back surface 250b of the spacer member 250 of the upper game board 6 and the game board surface 200a of the lower game board 6, so that the game board surface 200a is damaged. Is prevented from sticking.

  In this embodiment, as shown in FIG. 10, the mounting bosses 260 c and 260 f are provided at two locations on the surface side of the game board 6, so that the upper game board 6 can be rotated horizontally with respect to the lower game board 6. Since the orientation of the upper game board 6 with respect to the lower game board 6 is determined by regulation, not only the stability when stacking a plurality of game boards 6 is improved, but some impact is applied to the stacked game boards 6. The impact is distributed to the mounting bosses 260c and 260f and the fitting recesses 264c and 264f, and is not locally applied to the one mounting boss 260c and 260f and the fitting recesses 264c and 264f. Damage to the bosses 260c and 260f is prevented.

  In addition, the upper and lower sides of the game board 6 swing slightly in the front-rear direction around a virtual straight line passing through these two mounting bosses 260c and 260f. As a result, when the game boards 6 are stacked, a load is also applied to the upper side or the lower side of the lower game board 6, so that all the loads on the upper game board 6 are attached to the lower boss 260 c of the game board 6. , 260f is prevented from being concentrated on the two points, so that the mounting bosses 260c and 260f are prevented from being damaged. Note that the mounting bosses 260c and 260f may be provided at three or more locations, and all the loads of the upper game board 6 may be received and supported at the mounting boss arrangement position.

  In this embodiment, the mounting bosses 260c and 260f and the fitting recesses 264c and 264f are formed in a circular shape in the cross section, but the mounting bosses 260c and 260f and the fitting recesses 264c and 264f are formed in a non-circular cross section. By making the shape, horizontal rotation of the upper game board 6 relative to the lower game board 6 may be restricted. Specifically, the mounting bosses 260c and 260f and the fitting recesses 264c and 264f have, for example, a polygonal shape, an elliptical shape or the like, or a circular convex portion and a concave portion for restricting relative rotation. If a key (locking piece) and a key groove (locking groove) are formed, when the mounting bosses 260c and 260f are fitted into the fitting recesses 264c and 264f, the shaft centers of the mounting bosses 260c and 260f are aligned. The relative rotation of both the centers can be restricted. In this case, the horizontal rotation of the upper game board 6 relative to the lower game board 6 can be restricted even with one mounting boss and the fitting recess.

  In addition, fitting recesses 264c and 264f are formed at positions corresponding to the mounting bosses 260c and 260f, and the mounting bosses 260c and 260f have screw holes 206k extending from the tip to the fitting recesses 264c and 264f at the lower end. By being formed so as to penetrate in the vertical direction, in the state in which the mounting bosses 260c and 260f are fitted in the fitting recesses 264c and 264f, the openings on the distal end side of the mounting bosses 260c and 260f of the screw holes 206k are opened. And the openings on the inner surface side of the fitting recesses 264c and 264f match, so that when the plurality of game boards 6 are stacked, the screw holes 206k of the upper and lower game boards 6 and 6 communicate in the vertical direction. Therefore, for example, in a stacked state, the wire board (for example, a metal rod or string) is inserted into the screw holes 206k from above the uppermost game board 6 into the screw holes 206k. Can be prevented more effectively.

  Further, the game board 6 is the same as the game board made of veneer plywood as in the prior art by integrally assembling the board plate 200 having the thickness width dimension P1 of about 1 cm to the spacer member 250 having the thickness width dimension P2 of about 1 cm. Since it is formed in the shape and the same wall thickness (about 2 cm), it is possible to perform mounting holes and nailing using a production line for manufacturing a game board made of veneer plywood.

  In this way, by combining the board surface plate 200 made of an acrylic resin material and the spacer member 250 to form the game board 6 having a predetermined thickness, the game board 6 having a predetermined wall thickness is formed only by the board surface board 200. Compared to the case, not only the manufacturing cost can be reduced, but also a lightweight game board can be configured. Further, since the back surface 200b side of the transparent board plate 200 is protected by the spacer member 250, the board plate 200 is prevented from being damaged or broken during manufacturing or transport.

  Next, the structure of the game board 6 in which various members are attached to the front face of the board face plate 200 will be described with reference to FIGS. FIG. 12 is a perspective view showing how various members are attached to the front side of the game board. FIG. 13 is a front view showing a state in which various members are attached to the front surface of the game board. FIG. 14 is a perspective view showing the ball return prevention device.

FIG. FIG. 27 is a cross-sectional view showing a modification of the structure for attaching the game member to the game board surface. 28A is a cross-sectional view showing a structure for attaching the outer rail decoration to the game board surface, and FIG. 28B is a cross-sectional view showing a modification of the structure for attaching the outer rail decoration to the game board surface.

  As shown in FIG. 12 and FIG. 13, the game board surface 200a of the board surface plate 200 in the game board 6 is a ball hitting rail comprising an outer rail 500a and an inner rail 500b. 500, outer rail decorations 600a to 600c, obstacle nail K, windmill, certificate sticking member 601, ball return prevention device 700 and the like are attached, center frame decoration 11, variable winning ball device 15, special variable winning ball device 20, gate 32, decorative members 25L, 25R, and the like are attached to the attachment holes 201 to 206 from the front side.

  These hitting rails 500, outer rail decorations 600a to 600c, obstacle nails K, windmills, ball return prevention device 700, center frame decoration 11, variable winning ball device 15, special variable winning ball device 20, gate 32, decorative members 25L and 25R Is a game structure disposed on the game board surface 200a, of which the batting rail 500 except the outer rail decorations 600a to 600c disposed around the game area 7, the obstacle nail K, the windmill, and the ball return prevention The device 700, the center frame decoration 11, the variable winning ball device 15, the special variable winning ball device 20, the gate 32, and the decorative members 25L and 25R are arranged in the game area 7 so as to be an obstacle to the flow of the game ball. A flow direction changing member for changing the flow direction of the sphere is configured.

  Further, the outer rail decorations 600a to 600c are arranged around the game area 7 on the game board surface 200a, so that the end portions of the guide surfaces 601a to 601c having a circular arc when viewed from the front are provided on the game board surface 200a. They are connected to each other to form an annular guide surface (see FIG. 13). In addition, since the outer rail 500a is arrange | positioned along the inner side of the guidance surface 601a, it has substantially comprised the guidance surface 601a. As described above, the guide surfaces 601a to 601c divide the game board surface 200a into a circular game area 7 formed at the center and a non-game area formed around the game area 200a. The rail 500 a constitutes a rail member that forms the game area 7.

(Hitball rail)
The hitting rail 500 is an outer rail disposed in an arc shape along the left peripheral edge of the game area 7 formed in a substantially circular shape from the lower part of the game board surface 200a of the board board 200 when the game board 6 is viewed from the front side. 500a and an inner rail 500b that is spaced apart from the inner side of the outer rail 500a. A game ball launched by the ball striking device is placed in the gaming area 7 between the outer rail 500a and the inner rail 500b. A guiding passage 502 for guiding is configured.

  The hitting rail 500 is formed of a band-shaped metal plate, and a plurality of mounting pins 501 (see FIG. 17) fixed to the edge portion H on the game board surface 200a side in the longitudinal direction at predetermined intervals are provided on the game board surface 200a. By press-fitting into the plurality of mounting holes TB formed, a gap is provided between the edge H and the game board surface 200a (see FIG. 20). Thus, by providing a gap between the edge portion H and the game board surface 200a and attaching the game ball to the side surface of the batting rail 500, even if vibration occurs and the edge portion H and the game board surface 200a are connected. Since there is no rubbing, there is a low possibility that the powder generated by scraping the game board surface 200a will adhere to the game board surface 200a and the game board surface 200a will become dirty.

  Note that the edge H on the game board surface 200a side in the batting rail 500 is the outer peripheral side of the opposing surface (rear end surface) facing the game board surface 200a in the batting rail 500, and is on the opposite end surface (front end surface). The peripheral edge is not included.

  In addition, the outer rail 500a and the inner rail 500b are separated by a width that is slightly larger than the diameter of the game ball, so that the game ball moving in the guide passage 502 is guided by the outer rail 500a or the inner rail 500b. At least the ball is returned because the ball hits the side surface (standing surface) facing the passage 502 so as to slide or roll in many cases, and the game ball is unlikely to fall on the side surface and generate a large vibration in the hitting rail 500. If the gap is formed between the game board surface 200a and the edge H on the end side to which the prevention device 700 is attached, the edge H and the game board surface 200a will not rub against each other, so that the game board surface 200a is scraped. The possibility that the generated powder adheres to the game board surface 200a and the game board surface 200a becomes dirty is low.

(Outer rail decoration)
As shown in FIG. 12, the outer rail decorations 600 a to 600 c include an outer rail decoration 600 a in which a guide surface 601 a of a game ball is formed along the left edge of the game area 7, and the center of the right edge from the upper edge of the game area 7. An outer rail ornament 600b in which a game ball guiding surface 601b is formed along the portion, and an outer rail ornament 600c in which a game ball guiding surface 601c is formed along the lower edge from the center of the right edge of the gaming area 7. ,including.

  The outer rail decoration 600a is attached by screwing attachment screws 602a to 602d into screw holes formed at the distal ends of the mounting bosses 260a to 260d, and the outer rail decoration 600b is attached to the distal ends of the mounting bosses 260e and 260f. The outer rail decoration 600c is screwed into the screw holes formed at the tips of the mounting bosses 260g and 260h, and the mounting screws 602g and 602h are screwed into the screw holes formed in the screw holes 602e and 602f. It is attached by doing.

  These outer rail decorations 600a to 600c have a three-dimensional arc-shaped main body 603 standing on the game board surface 200a, and guide surfaces 601a to 601c are formed on the outer surface of the inner wall 603a of the main body 603. The front end 604 of the inner wall 603a protrudes to the front side of the front surface of the main body 603 (see FIGS. 20 to 23). That is, the front end portion 604 that is suspended from the front surface of the main body portion 603 is an arc-shaped protruding piece that extends along the guide surfaces 601a to 601c.

  As shown in FIGS. 20 to 23, a notch groove KM is formed in the edge portion H on the guide surfaces 601a to 601c side of the edge portion H on the game board surface 200a side in the inner wall 603a, and between the game board surface 200a. A gap (for example, a height of about 0.3 mm and a width of about 2 mm (for example, see FIG. 20)) extends in the longitudinal direction. Thus, a gap is formed between the edge H and the game board surface 200a by the notch recessed groove KM formed in the edge H on the guide surfaces 601a to 601c side on the rear end surface of the inner wall 603a, and the guide surfaces 601a to 601c. Even if the inner wall 603a is vibrated by contact with the game ball, the edge H and the game board surface 200a are not rubbed, so that the powder generated by scraping the game board surface 200a adheres to the game board surface 200a. The game board surface 200a is not soiled.

  The edge H on the game board surface 200a side of the inner wall 603a of each of the outer rail decorations 600a to 600c is the outer peripheral side of the opposing surface (rear end surface) facing the game board surface 200a on the inner wall 603a. The peripheral edge of the end face (front end face) is not included. That is, a portion other than the notch groove KM on the rear end surface of the inner wall 603a and a rear end surface of the main body 610 other than the inner wall 603a are in contact with the game board surface 200a.

  Although the outer rail decoration 600b is not shown in FIGS. 20 to 23, the notch groove KM is formed in the edge H on the game board surface 200a side of the inner wall 603a as in the outer rail decorations 600a and 600c. Even if vibration is generated on the inner wall 603a due to the game ball coming into contact with the guide surface 601b, the edge H and the game board surface 200a are not rubbed, so that the powder generated by scraping the game board surface 200a is removed from the game board surface 200a. The game board surface 200a does not get dirty due to adhesion.

  As shown in FIGS. 12 and 22, the outer rail decoration 600 c has a cylindrical portion 605 fitted from the front side into the out opening hole 204 of the board surface plate 200 and the out opening 262 of the spacer member 250. It continues from the lowest position in 601c toward the back side. Thus, the game ball guided (flowed down) toward the cylindrical portion 605 integrally formed with the outer rail decoration 600c by the guide surface 601c is guided into the out port 26 serving as the front opening of the cylindrical portion 605. Then, it is discharged to the back side of the game board 6 (see FIG. 22).

  Further, as shown in FIGS. 13, 22 and 23, the position near the out port 26 on the guide surface 601c of the outer rail decoration 600c is arranged upward at the lower position of the game area 7, and the guide surface 601c. The game ball is not only guided by rolling along the line, but is also a part where the game ball flowing down from above is frequently dropped and easily vibrates due to the impact of the fall of the game ball. Therefore, the outer rail ornament 600c is a game by fitting the cylindrical portion 605 formed integrally with the outer rail ornament 600c into the out opening hole 204 of the panel board 200 and the out opening 262 of the spacer member 250 from the front side. Since it is firmly attached to the board surface 200a and the occurrence of vibrations is suppressed, the edge H of the inner wall 603a on the game board surface 200a side and the game board surface 200a are less likely to rub, and the game board surface 200a is less likely to be scraped off to produce powder. Become.

  FIG. 28 (a) shows a structure for attaching the outer rail decoration 600a to the game board surface 200a. The outer rail decoration 600a is attached to the game board surface 200a by screwing the mounting screws 602a to 602d through screw holes 260k formed through the mounting bosses 260a to 260d from the front side, and protrudes from the rear side. The attachment position can be determined by fitting the positioning pin 660 thus formed into a positioning hole 209 formed through the board surface plate 200 from the front side.

  As described above, the outer rail decoration 600a is attached to the tips of the mounting bosses 260a to 260d formed on the spacer member 250, so that the powder scraped by directly screwing the mounting screws 602a to 602d into the board surface plate 200. The game board surface 200a is not soiled by adhering to the surroundings. Further, since the board surface plate 200 is sandwiched between the outer rail decoration 600a and the spacer member 250, the outer rail decoration 600a can be attached to the board surface board 200 and the spacer member 250 without using separate screw members or the like. The mounting screws 602a to 602d can be assembled together.

  Further, the positioning pin 661 on the spacer member 250 side may be fitted from the back side of the positioning hole 209 into which the positioning pin 660 of the outer rail decoration 600a to 600c is fitted from the front side. Since the positioning holes can be shared between the outer rail decorations 600a to 600c and the spacer member 250, the strength reduction of the panel board 200 can be prevented as compared with the case where each positioning hole is formed separately. Not only can it be done, it can save the labor of drilling.

  Since the outer rail decorations 600b and 600c are attached to the spacer member 250 with the same attachment structure as the outer rail decoration 600a, detailed description of the attachment structure is omitted.

  Further, regarding the outer rail decorations 600a and 600b, the mounting bosses 260c and 260f in which the screw holes 260k for mounting the mounting screws 602c and 602f are formed protrude to the front side from the game board surface 200a, so that the rear end surface of the outer wall 603b A positioning recess 662 into which the tip ends of the mounting bosses 260c and 260f can be fitted is provided at a position corresponding to the screw insertion hole 663. Therefore, the mounting positions of the outer rail decorations 600a and 600b with respect to the game board surface 200a can be easily determined by fitting the front ends of the mounting bosses 260c and 260f into the positioning recess 662.

  When the mounting screws 602c and 602f are screwed into the screw holes 260k, the tip ends of the mounting bosses 260c and 260f do not contact the inner upper surface of the recess 662, and the rear end surface of the outer wall 603b, that is, the outer wall Outer rail decorations 600a and 600b are arranged in a state in which the edge H on the game board surface 200a side in 603b is in contact with the game board surface 200a. For example, as shown in FIG. When the mounting screws 602c and 602f are screwed into the holes 260k, the tip ends of the mounting bosses 260c and 260f and the inner upper surface of the recess 662 come into contact with each other, and the edge H on the game board surface 200a side of the outer wall 603b is the game board surface. It may be arranged so as not to come into contact with 200a, that is, away from the game board surface 200a.

  By doing so, the edge H on the game board surface 200a side of the outer wall 603b and the game board surface 200a are not rubbed, and the plurality of game boards 6 are stacked when the plurality of game boards 6 are stacked as will be described later. Even when a load is applied to the outer rail decorations 600a and 600b (see FIGS. 29 and 30), the load is applied directly to the spacer member 250 instead of the board plate 200, The contact of the outer wall 603b with the edge H on the game board surface 200a side prevents the game board surface 200a from being scraped and generating powder.

(Ball return prevention device 700)
Next, the structure of the ball return device 700 will be described with reference to FIGS.

  As shown in FIGS. 14 to 16, the ball return device 700 includes a plate-like opening / closing part 701 provided so as to be able to open and close a connecting part 503 (see FIG. 13) that connects the guide passage 502 and the game area 7. It is attached to the downstream end of the rail 500b (the upper end of the inner rail 500b in FIG. 13), that is, the end on the side of the connecting portion 503 near the exit of the guide passage 502, and supports the opening / closing portion 701 so as to be swingable. The mounting support portion 702 is mainly configured.

  The opening / closing part 701 is a launching ball contact surface 703a with which a game ball launched from the hitting ball launching device comes into contact, and a side surface opposite to the launching ball contact surface 703a, from the game area 7 toward the guide passage 502 side. A plate-shaped contact portion 703 having a return ball contact surface 703b with which the returning game ball contacts, a swinging shaft portion 704, and a contact portion 703 arranged on the opposite side of the swinging shaft portion 704 to communicate with each other. A weight portion 705 for urging the contact portion 703 toward the closed position for closing the portion 503.

  A concave portion 706 that can accommodate the swinging shaft portion 704 and the weight portion 705 of the opening / closing portion 701 is provided on the surface of the attachment support portion 702 on the guide passage 502 side. Further, on the side of the recess 706, a pair of insertion pieces 707a and 707b into which the end portion on the connecting portion 503 side of the inner rail 500b is inserted, and an end portion of the inner rail 500b inserted into the insertion pieces 707a and 707b An elastic engagement claw 708 that can be elastically engaged is formed in the engagement hole 504 formed in the above.

  On both sides of the recess 706, there are formed a wall portion 709a disposed opposite to the game board surface 200a of the board surface plate 200 at the time of mounting, and a wall portion 709b on the opposite side. An insertion hole 711 through which the swing shaft 710 of the portion 701 can be inserted from the outside is formed, and a shaft hole formed in the swing shaft portion 704 of the opening / closing portion 701 from the insertion hole 711 inside the wall portion 709b. A screw hole 712 into which a male screw portion formed at the tip of the swing shaft 710 inserted through 713 is screwed is formed. The swing shaft 710 may be a pin member instead of a screw member.

  In addition, a screw accommodation hole 714 into which a general-purpose screw member 715 used in assembly of the pachinko gaming machine 1 or the like can be screwed is formed in the weight portion 705 of the opening / closing portion 701 in parallel with the shaft hole 713. The screw member 715 is screwed into the screw receiving hole 714 so that the center of gravity is biased toward the weight portion 705 side. In this way, a general-purpose screw member 715 used in assembling the pachinko gaming machine 1 or the like is screwed into the screw receiving hole 714 without using special parts or the like or molding the opening / closing part 701 by a special method. Since the center of gravity can be biased toward the weight portion 705 alone, the opening / closing portion 710 can be easily formed, and the manufacturing cost can be reduced.

  Further, a substantially C-shaped protrusion 716 protrudes from a peripheral edge portion of the insertion hole 711 on the outer surface of the wall portion 709a and comes into contact with the game board surface 200a at the time of attachment.

  As shown in FIGS. 17 and 18, the ball return device 700 configured as described above is attached to the inner rail 500b by inserting the end of the inner rail 500b into the insertion pieces 707a and 707b. The inner rail 500b of this embodiment is attached to the game board surface 200a by press-fitting each attachment pin 501 into each attachment hole TB formed in the game board surface 200a. It is necessary to press-fit each mounting pin 501 into each mounting hole TB by holding the vicinity of 501 with a clamping tool (not shown).

  As shown in FIG. 17, the mounting pin 501 is provided in the vicinity of the end of the inner rail 500 b on the side where the ball return device 700 is attached so as not to swing due to an impact caused by contact with the pachinko ball of the ball return device 700. Therefore, when the end portion of the inner rail 500b is clamped by a clamping device in order to press-fit the mounting pin 500 into the mounting hole TB, the ball return device 700 attached to the end portion is clamped. Since the return device 700 is damaged, it is necessary to attach the ball return device 700 after attaching the inner rail 500b to the game board surface 200a.

  In order to attach the ball return device 700 to the end portion of the inner rail 500b attached to the game board surface 200a, the end portion of the inner rail 500b is inserted into the insertion pieces 707a and 707b with the protrusion 716 facing the game board surface 200a. Just plug it in.

  Then, by inserting the insertion pieces 707a and 707b into the end portion of the inner rail 500b, the elastic engagement portion 708 is elastically engaged with the engagement hole 504 and the movement in the removal direction is restricted. The mounting support 702 is attached to the end of the inner rail 500b simply by inserting the insertion pieces 707a and 707b even in the state where the end is firmly attached to the game board surface 200a by the mounting pin 501. be able to. As described above, even when the inner rail 500b is fixed to the game board surface 200a, the attachment support portion 702 can be easily attached to the inner rail 500b simply by elastically engaging the elastic engagement portion 708 with the engagement hole 504. Therefore, when the inner rail 500b is fixed to the game board surface 200a, it is possible to prevent the ball return prevention device 700 from getting in the way and the ball return prevention device 700 from being damaged.

  Further, the mounting pin 501 is disposed at a position away from the end of the inner rail 500b so that the mounting pin 501 can be press-fitted into the mounting hole TB with the mounting support 702 attached to the end of the inner rail 500b. Thus, when the ball return prevention device 700 comes into contact with the game ball, the end of the inner rail 500b does not easily vibrate.

  In addition, in the state where it is attached to the end portion of the inner rail 500b, the entire outer surface of the wall portion 709a facing the game board surface 200a, including the edge portion H on the game board surface 200a side in the attachment support portion 702 contacts the game board surface 200a. Since only the front end surface of the protrusion 716 formed on the inner side of the edge H on the game board surface 200a side in the mounting support portion 702 contacts the game board surface 200a, the impact due to the contact with the game ball and the opening / closing portion Even if the powder generated by the vibration of the mounting support portion 702 due to the swinging of the 701 and the tip surface of the protrusion 716 and the gaming board surface 200a being rubbed and scraping the gaming board surface 200a adheres to the gaming board surface 200a, Since powder is concealed by covering the periphery of the protrusion 716 with the wall portion 709a, the game board surface 200a is not conspicuously soiled.

  The edge portion H on the game board surface 200a side in the attachment support portion 702 is the outer peripheral side portion of the opposite surface (outer surface of the wall portion 709a) facing the game board surface 200a in the attachment support portion 702, and the opposite surface. The peripheral side of (the outer surface of the wall portion 709b) is not included.

  Further, since the protrusion 716 is formed around the swing shaft 710, the mounting support portion 702 is not only stably supported, but also swings with respect to the mounting support portion 702 by swinging of the opening / closing portion 701. Even if vibration in the direction of rotation about the shaft 710 occurs, the ridge 716 only rotates about the swing shaft 710 and does not slide on the game board surface 200a, so the ridge 716 and the game board surface The powder scraped off by rubbing with 200a is not easily scattered around.

(Decorative member)
The decorative members 25L and 25R are attached to the attachment holes 206a and 206b. The decorative members 25L and 25R have substantially the same internal structure although the external shapes are different. Therefore, only the structure of the decorative member 25L will be described below, and the structure of the decorative member 25R will be omitted. As shown in FIG. 21, the decorative member 25L is fitted into the mounting hole 206a from the three-dimensional main body 610 standing on the game board surface 200a so as to be an obstacle to the flow of the game ball, and the bottom surface of the main body 610.

It is arrange | positioned at the periphery of 206a and the periphery part 611a can be attached now with the attachment screw 613. FIG. Further, a notch groove KM is formed in the edge H of the peripheral edge 611a, that is, the edge H of the main body 611 on the game board surface 200a side. A gap is formed between the edge portion H and the game board surface 200a by the notch groove KM, and even if vibration occurs due to the game ball coming into contact with the peripheral surface of the main body portion 611, the edge portion H and the game board surface 200a. Therefore, the powder generated by scraping the game board surface 200a does not adhere to the game board surface 200a and the game board surface 200a is not soiled.

  The edge H on the game board surface 200a side of the inner wall 603a of the main body 610 is the outer peripheral side of the facing surface (rear end face) facing the game board surface 200a on the inner wall 603a, and the opposite end face (front end face). ) Is not included.

  In addition, since the notch groove KM is formed on the entire periphery of the main body 610, the edge H of the place where the game ball flowing down the game area 7 in the main body 610 can directly drop or come into contact with the game board surface 200a Will not rub.

(Center frame decoration)
The center frame ornament 11 as another example of the decorative member is attached to the attachment hole 201. As shown in FIG. 25, the center frame decoration 11 is provided with a frame-shaped main body portion 630 attached to the peripheral portion of the mounting hole 201, and protrudes outward from the peripheral surface of the main body portion 630. The flange portion 631 is disposed at the peripheral edge of the mounting hole 201 in the mounting hole 201, and the flange portion 631 can be attached to the game board surface 200 a with the mounting screw 633.

  The main body 630 is fitted into the mounting hole 201, and a decorative portion is formed on the front surface. In addition, since the notched groove KM is formed in the edge portion H on the game board surface 200a side in the flange portion 631, a gap is formed between the edge portion H and the game board surface 200a by the notched groove KM. Even if the game ball comes into contact with the front surface of the part 630 and vibration occurs, the edge H and the game board surface 200a are not rubbed, so that the powder generated by scraping the game board surface 200a adheres to the game board surface 200a. Thus, the game board surface 200a is not soiled.

  The edge H on the game board surface 200a side of the inner wall 603a of the main body 610 is the outer peripheral side of the facing surface (rear end face) facing the game board surface 200a on the inner wall 603a, and the opposite end face (front end face). ) Is not included.

  Since the notch groove KM is formed on the entire periphery of the main body 630, the edge H of the portion where the game ball flowing down the game area 7 can directly drop or abut on the main body 630 and the game board surface 200a. Will not rub.

The elastic locking claw 648 is provided so as to protrude from the opening of the mounting hole 201 to the back surface 200b side of the board surface plate 200 in a state where the gate member 32b is attached to the game board surface 200a. The projecting portion is elastically deformed to be engaged with and disengaged from the main body of the gate switch 32a.

  Further, since the notch groove KM is formed in the edge portion H on the game board surface 200a side in the flange portion 643, a gap is formed between the edge portion H and the game board surface 200a by the notch groove KM, and the frame Even if a game ball comes into contact with the ridge portion 640 and vibration occurs, the edge H and the game board surface 200a are not rubbed, so that the powder generated by scraping the game board surface 200a adheres to the game board surface 200a. The game board surface 200a is not soiled.

  The edge portion H on the game board surface 200a side in the flange portion 643 is the outer peripheral side portion of the opposing surface (rear surface) facing the game board surface 200a in the flange portion 643, and the peripheral edge on the opposite surface (front surface). Is not included.

  Since this notch groove KM is formed on the entire periphery of the flange portion 643, the edge portion H and the game board surface 200a where the game ball flowing down the game area 7 can directly drop or abut on the flange portion 643. Will not rub.

  The gate 32 configured as described above fits the fitting portions 646 and 646 of the gate member 32b into the mounting hole 205 from the game board surface 200a side, and plays the positioning pin 647 protruding from the rear surface of the flange portion 643. It is attached by fixing the mounting screw 642 to the game board surface 200a in a state of being fitted and positioned in a positioning hole formed on the board surface 200a.

  And the rear part of the main body is elastically locked by inserting the main body of the gate switch 32a from the back surface 200b side of the panel board 200 into the insertion hole 649 of the gate member 32b arranged in the opening of the mounting hole 201 toward the front surface side. It is locked to the claw 648 and attached to the gate member 32b. Further, the gate switch 32a can be easily removed simply by deforming the elastic locking claw 648 and releasing the locked state.

  Thus, the opening 32c which comprises the channel | path part which a game ball can pass is arrange | positioned at the game board surface 200a side, and the gate switch 32a which detects the game ball which passes this opening 32c is attached to the game board surface 200a side. By being configured to be detachable from the back surface 200b side of the panel board 200 with respect to 32b, wiring (see FIG. 26 (b)) extending from the rear part of the main body of the gate switch 32a, and the wiring on the substrate or the like A connector (not shown) or the like for connection can be attached without being inserted into the attachment hole 205. For example, when the gate switch 32a breaks down and replacement or maintenance is necessary, the gate member 32b is attached. Only the gate switch 32a can be replaced without being removed. Further, since the side end surface of the main body of the gate switch 32a is covered by being inserted into the frame-like portion 640 of the gate member 32, damage or breakage due to contact with the game ball is prevented.

  As described above, in this embodiment, the outer rail decorations 600a to 600c, the decoration members 25L, 25R, and 600, the center decoration 11, the gate member 32, the variable winning ball apparatus 15 and the like are disposed in the game area 7. A gap is formed between the edge portion H and the game board surface 200a by forming a notch groove KM in the edge portion H on the game board surface 200a side in the main body of the game member. In addition, by projecting a convex portion (abutment portion) at a predetermined position on the opposing surface of the main body portion of the gaming member facing the game board surface 200a, and installing only the convex portion on the gaming board surface 200a, the main body of the gaming member A gap may be formed between the edge H on the game board surface 200a side and the game board surface 200a.

  Further, the notch groove KM formed in the edge portion H of these game members is along the game ball contact surface that may contact the game ball in each game member, that is, along the edge portion H facing the game area 7. As long as it is formed, it does not necessarily have to be formed on the entire peripheral edge of the main body.

  Further, a cushioning material such as a rubber material that can absorb vibrations may be fitted into a gap formed between the game board surface 200a by the cutout concave groove KM formed in each game member. By doing so, it is possible to prevent powder or the like that has been scraped off by rubbing against the game board surface 200a on the inner side of the notch groove KM from being scattered around.

(Game board loading)
FIG. 29 is a perspective view showing a state in which a plurality of game boards to which various members are attached are stacked. 30 is a cross-sectional view taken along line RR in FIG.

  As described above, the game board 6 in which various game structures (flow direction changing members) are attached to the game board surface 200a can be stacked vertically as shown in FIG. As mentioned above, after attaching the ball striking rail and the small prize-winning device to be described later after nailing, large parts such as a large prize-winning device and a control circuit board are attached, but the assembly process is complicated. Since the attaching speed decreases, the game board may be stacked and waited after the nailing and the small winning device is attached.

  When the game boards 6 are stacked in the vertical direction in this way, as shown in FIG. 30, the front end portions 604 of the outer rail decorations 600a to 600c of the game boards 6 are placed on the spacer members 250 of the game boards 6 stacked upward. By engaging each of the formed arc-shaped engaging step portions 267, the skidding of the upper game board 6 with respect to the lower game board 6 is restricted and sliding is prevented, and the loading position is determined. As shown in the figure, a plurality of game boards 6 can be stacked in the vertical direction.

  Specifically, the front end portion 604 made of an arc-shaped piece is formed in an annular shape (circular shape) when viewed from the front so as to extend along the guide surfaces 601a to 601c that are suspended along the periphery of the game area 7. As a whole, a convex portion protruding from the game board surface 200a is formed (see FIGS. 13 and 30). On the other hand, the engagement step portion 267 is vertically provided on the outer peripheral edge of the contact surface 267a and the corresponding contact surface 267a formed in a C shape in the rear view along the peripheral edge of the opening 251 on the back surface 250b of the spacer member 250. By forming the control surface 267b, a concave portion is formed as a whole on the back surface 250b (see FIGS. 30 and 31).

  Therefore, when the front end portion 604 of the lower game board 6 is fitted into the engagement step portion 267 of the upper game board 6, the restriction surface 267 b is arranged on the outer periphery of the front end portion 604 and the horizontal movement is performed. Since the contact is restricted, the convex portion formed of the front end portion 604 having an annular shape (circular shape) when viewed from the front is fitted into the concave portion including the engaging step portion 267 having an opening having a C-shape when viewed from the back. In this embodiment, the restricting surface 267b of the locking step portion 267 is suspended from the outer peripheral edge of the contact surface 267a. However, the restricting surface 267b may be suspended from the inner peripheral edge. When engaged, a regulating surface 267b is arranged inside the front end portion 604, and the movement in the horizontal direction is abutted and regulated.

  Further, as shown in FIG. 13, the front end portion 604 that engages with the engaging step portion 267 is disposed on the outer rail decorations 600a to 600c, so that the load of the upper game board 6 is distributed to the non-game area. In addition to the outer rail decorations 600a to 600c provided, the load applied to the outer rail decorations 600a to 600c is supported by the spacer member 250 as described above. That is, since the load of the upper game board 6 is equally applied to the periphery of the circular game area 7, not only the stability of the loaded game board 6 is improved, but also the load is applied directly to the game area 7 of the board surface board 200. Since it is not added, the board surface plate 200 is prevented from being bent or damaged.

  The height P20 of the obstacle nail K provided in the game area 7 is longer than the height P15 of the outer rail decorations 600a to 600c up to the front end 604. The combined dimension (P15 + P22) of the height dimension P15 of 600a to 600c and the depth dimension P22 of the concave accommodation space (relief part) formed by the back surface 200b of the panel board 200 and the opening 251 is the obstacle nail K. Is longer than the height dimension P20 (P15 + P22> P20).

  Therefore, among the flow direction changing members provided in the game area 7, the back surface 250b of the spacer member 250 is provided even if the obstacle nail K or the like is provided so as to protrude from the front end portion 604 of the outer rail decorations 600a to 600c to the front side. In addition, a concave relief portion having a size capable of accommodating the obstacle nail K is formed by the back surface 200b of the board surface plate 200 and the opening portion 251, so that when the game board 6 is stacked, the lower game board Since the front end portion of the six obstacle nails K is accommodated in the escape portion, there is no interference with the upper game board 6 during stacking.

  Further, the protruding length dimension P16 of the front end portion 604 protruding from the front surface of the main body portion 603 of the outer rail decorations 600a to 600c is longer than the depth dimension P17 of the engaging step portion 267 (P16> P17). Thus, in the state where the front end portions 604 of the outer rail decorations 600a to 600c are engaged with the engagement step portions 267 of the game board 6 stacked above, the main body portions of the outer rail decorations 600a to 600c Since a gap P18 having a predetermined width is formed between the front surface of various members including 603 and the back surface of the upper game board 6 (the back surface 250b of the spacer member 250), it is prevented from being damaged due to contact with each other. Is done.

  Further, the load on the upper game board 6 is not applied to the flow direction changing member (obstacle) such as the obstacle nail K provided in the game area 7, and the outer rail decorations 600 a to 600 c arranged outside the game area 7. As a result, the flow direction changing member is not deformed and the flow of the game ball is not hindered.

  Further, in the present embodiment, the convex front end portion 604 that fits into the concave engagement step portion 267 is formed on the outer rail decorations 600a to 600c that are examples of the game structure. Are provided on the flow direction changing member such as the outer rail 500a of the hitting rail 500, the center frame decoration 11, the variable winning ball device 15, the special variable winning ball device 20, the gate 32, the decorative members 25L and 25R, and the back surface of the spacer member 250. A concave portion is formed at a position corresponding to the convex portion in 250b, and the convex portion provided on the flow direction changing member when stacked is fitted into the concave portion.

  In this embodiment, the annular front end portion 604 is fitted to the C-shaped engagement step portion 267. However, the convex portion and the concave portion are limited to those formed in this manner. Instead, it may be formed of a rod-shaped convex portion and a bottomed hole-shaped concave portion. Moreover, the horizontal rotation of the upper game board 6 centering on a convex part can be controlled by making the external shape of a convex part or a recessed part into a non-circular shape, or forming a recessed part in a some convex part.

  In this embodiment, since the spacer member 250 is attached to the back surface 200b of the board surface plate 200, the engaging step portion 267 is formed on the back surface 250b of the spacer member 250, but the spacer member 250 is attached to the game board surface 200a. In the case of mounting on top (see, for example, FIG. 36), the engaging step portion 267 may be formed on the back surface 200b of the panel board 200.

(Attaching the component unit to the game board)
Next, attachment of the component unit to the game board will be described with reference to FIGS. FIG. 31 is a rear view showing a gaming board in which a flow direction changing member is attached to the gaming board surface. 32A is an SS cross-sectional view of FIG. 31, and FIG. 32B is a TT cross-sectional view of FIG. FIG. 33 is an enlarged perspective view showing a guide groove. FIG. 34 is a perspective view showing a state in which the component unit is attached to the game board. FIGS. 35A and 35B are schematic views showing the arrangement positional relationship of the cover body positioning holes, and FIGS. 35B and 35C are schematic diagrams showing modifications of the arrangement positional relationship of the cover body positioning holes.

  As shown in FIGS. 31 and 32, positioning bosses 312 a to 312 d provided on the cover body 302 can be fitted to the upper left and right sides and the lower left and right sides of the opening 251 in the back plate 252 of the spacer member 250. Circular cover body positioning holes 265a to 265d are formed. In this embodiment, the cover body positioning holes 265a to 265d and the back surface 200b of the panel board 200 form recesses into which the positioning bosses 312a to 312d can be fitted. A recess may be formed directly on 252.

  FIG. 35 is a schematic view showing the relationship between the upper left and right cover body positioning holes 265a and 265b and the positioning bosses 312a and 312b. When viewed from the back side, the inner diameter (width dimension) L1 of the right cover body positioning hole 265a is larger than the inner diameter L2 of the left cover body positioning hole 265b (L1> L2). The positioning bosses 312a and 312b have the same outer diameter L5, a smaller diameter (L5 <L1) than the inner diameter L1 of the cover body positioning hole 265a, and substantially the same size as the inner diameter L2 of the cover body positioning hole 265a. (L5≈L1) or the outer diameter L5 is slightly smaller than the inner diameter L2. That is, the difference dimension L14 (L1-L5) between the inner diameter L1 of the cover body positioning holes 265a and 265d and the outer diameter L5 of the positioning bosses 312a and 312d is equal to the inner diameter L2 of the cover body positioning holes 265b and 265c. It is larger than the difference dimension (L2−L5) from the outer diameter L5 of the bosses 312b and 312c (L1−L5> L2−L5).

  Further, the left cover body positioning hole 265b as the second recess has a positioning boss as the first protrusion with respect to the cover body positioning hole 265a as the right first recess serving as a reference in positioning. A difference dimension L14 between the inner diameter (width dimension) L1 of the positioning hole 265a for the cover body and the outer diameter (width dimension) of the positioning boss 312a from the separation width dimension L10 of the positioning boss 312b as the second convex portion 312a. (= L1-L5) is subtracted by a separation width dimension L11 which is intermediate between a minimum width dimension L12 (L10-L14) and a separation width dimension L10 and a maximum width dimension L13 (= L10) of the same dimension. Yes.

  The lower left and right cover body positioning holes 265c and 265d and the positioning bosses 312c and 312d are the same as the upper left and right cover body positioning holes 265a and 265b and the positioning bosses 312a and 312b shown in FIG. Since it is the same as the relationship, detailed description is omitted.

  As shown in FIGS. 31 and 32, guide concave grooves 266 a to 266 d (see FIGS. 32 and 33) extending to the peripheral edge of the opening 254 are recessed from the cover body positioning holes 265 a to 265 d in the vertical direction. It is installed. These guide grooves 266a to 266d are formed on the back surface 250b of the spacer member 250, and surround the bottom surface G1 that forms a guide region larger than the area of the cover body positioning holes 265a to 265d and the periphery of the bottom surface G1. The inner side surface G2 that constitutes a wall portion that is erected and has a height dimension shorter than the height dimension of the positioning bosses 312a to 312d is configured to be concave in a sectional view.

  Specifically, the guide region is a region having a size including the bottom surface G1 and the opening regions of the cover body positioning holes 265a to 265d, and the cover body positioning holes 265a to 265a are formed at the ends of the guide regions. 265d is formed. That is, the guide grooves 266a to 266d are formed in the belt-shaped guide region on the back surface 250b, and the cover body positioning holes 265a to 265d are formed in a part of the bottom region of the guide grooves 266a to 266d (the bottom surface G1 is A region excluding the cover body positioning holes 265a to 265d is formed from the guide region). Further, the depth dimension of the guide grooves 266a to 266d, that is, the height dimension L3 of the inner side surface G2 (the width dimension from the bottom surface G1 to the rear surface 250b) is smaller than the height dimension L4 of the positioning bosses 312a to 312d. With the dimensions (L3 <L4), the positioning bosses 312a to 312d are inserted into the cover body positioning holes 265a to 265d.

  The bottom surfaces G1 of the guide grooves 266a to 266d are formed so that the width dimension gradually becomes wider from the cover body positioning holes 265a to 265d toward the periphery of the opening 254, that is, as the distance is increased. Accordingly, after the tips of the positioning bosses 312a to 312d are placed on the wide portions of the guide grooves 266a to 266d, the tips of the positioning bosses 312a to 312d are slid toward the cover body positioning holes 265a to 265d. The cover body positioning holes 265a to 265d can be easily fitted.

  When attaching the gaming component unit 300 to the back surface 250b of the spacer member 250 configured in this way, as shown in FIG. 34, for example, the game board 6 is mounted on the mounting surface with the back surface facing upward. Then, the gaming component unit 300 is attached from above with the decorative body 301 assembled from the front side facing the gaming board 6.

  In this case, for example, it is determined whether to perform positioning from the upper cover body positioning holes 265a and 265b or the lower cover body positioning holes 265c and 265d among the plurality of cover body positioning holes 265a to 265d. The positioning bosses 312a and 312d are preferably fitted from the large-diameter cover body positioning holes 265a and 265d on the upper side or the lower side.

  Next, a specific example in the case of positioning using the upper cover body positioning hole 265a as a foothold will be described.

  First, as shown in FIG. 34, for example, after the game board 6 is installed on a predetermined installation surface with the back face up, the game component unit 300 is lifted, and the positioning bosses 312a-312d on the front side are moved to the game board. The game board 6 is disposed above the game board 6 so as to face the board 6.

  Then, the gaming component unit is arranged such that the positioning boss 312a is placed on the guide area formed by the cover body positioning hole 265a and the bottom surface G1 of the guide groove 266a provided continuously from the cover body positioning hole 265a. The upper side of 300 is lowered so as to tilt downward. At this time, the bottom surface G1 of the guide groove 266a is extended toward the opening 251 so as to gradually increase toward the periphery of the opening 254, that is, the bottom G1 is the opening area of the cover body positioning hole 265a. Since the area is larger than that, it can be placed in the guide groove 266a more easily than directly inserted into the cover positioning hole 265a.

  Next, when the positioning boss 312a is placed on the bottom surface G1 of the guide groove 266a, the positioning boss 312a covers the game component unit 300 (cover body 302) with the load applied on the bottom surface G1. The game component unit 300 is slid upward so as to move toward the body positioning hole 265a (see FIG. 33). At this time, the positioning boss 312a is guided toward the cover body positioning hole 265a by being guided by the inner surface G2 disposed on the left and right sides of the guide groove 266a. Accordingly, the positioning boss 312a is prevented from deviating from the bottom surface G1, and as the cover body positioning hole 265a is approached, the lateral displacement of the positioning boss 312a with respect to the cover body positioning hole 265a gradually increases. Therefore, the positioning boss 312a can be easily inserted into the cover body positioning hole 265a simply by sliding the gaming component unit 300.

  Then, with the positioning boss 312a inserted into the cover body positioning hole 265a in this way, the game component unit 300 is placed in the cover body positioning hole 265a around the positioning boss 312a as the back of the game board 6. Rotate horizontally with respect to. At this time, since the positioning boss 312a is surrounded by the inner peripheral surface of the cover body positioning hole 265a, the center of rotation is not greatly shifted. Therefore, the positioning boss 312b can be easily aligned with the cover body positioning hole 265b. Can be fitted. In this case, the positioning boss 312b may be once placed on the bottom surface G1 of the guide groove 266b, and then the positioning boss 312b may be slid toward the cover body positioning hole 265b to be fitted.

  Then, with the positioning bosses 312a and 312b inserted into the upper cover body positioning holes 265a and 265b, if the lower side of the gaming component unit 300 is tilted downward and lowered, the cover body positioning holes 265c and Positioning bosses 312c and 312d are fitted to 265d, whereby the mounting position of the game component unit 300 with respect to the game board 6 is determined. At this time, since the positioning bosses 312b and 312c are fitted in the upper and lower cover body positioning holes 265b and 265c on the left side when viewed from the back side, the horizontal displacement of the gaming component unit 300 with respect to the gaming board 6 is caused. Be regulated.

  As shown in FIG. 34, the gaming component unit 300 positioned on the back side of the game board 6 is formed on the back plate 252 of the spacer member 250 by attaching a mounting screw 313 to each mounting hole 314 from the back side. By screwing into the screw holes, the game board 6 is attached (fixed) in a predetermined posture at a predetermined attachment position on the back surface of the game board 6. In this way, the gaming component unit 300 is fastened to the back plate 252 of the spacer member 250, so that it is not necessary to form a screw hole or the like of the gaming component unit 300 on the board 200 on which the gaming area 7 is formed. Therefore, a decrease in the strength of the board surface plate 200 is prevented.

  As described above, the game board 6 is installed in a state facing the back side, and the positioning bosses 312a to 312d of the game component unit 300 are fitted into the cover body positioning holes 265a to 265d from above. In addition to being able to easily determine the mounting position of the game component unit 300 with respect to the game board 6, when the positioning boss 312a is fitted into the cover body positioning hole 265a, the cover body positioning hole 265a is used. The positioning boss 312a placed on the bottom surface G1 spreading around the periphery may be slid toward the cover body positioning hole 265a. At this time, the positioning boss 312a deviates from the bottom surface G1 by the inner surface G2. Since it is prevented from leaving the cover body positioning hole 265a, the game component unit 300 may be large or heavy. Even if there is, it is possible to perform a fitting operation of the cover body for positioning hole 265a of the positioning bosses 312a very easily.

  Further, the cover body positioning hole 265a is formed at a position in contact with the inner side surface G2, and the inner side surface G2 extends in the tangential direction of the circular cover body positioning hole 265a, that is, the inner side surface G2 is the cover body. Since the positioning boss 312a is continuously provided from the positioning surface 265a, the positioning boss 312a placed on the bottom surface G1 is slidably brought into sliding contact with the inner side surface G2 to thereby move the positioning boss 312a to the cover body positioning hole 265a. Can be reliably fitted.

  In this embodiment, the cover body positioning hole 265a is provided so as to be in contact with the inner side surface G2 erected on the peripheral edge of the end of the belt-shaped guide region. On the large guide region, the cover body positioning hole 265a may be provided at a position not in contact with the inner side surface G2 standing on the periphery of the guide region.

  Further, when the cover body positioning hole 265a is provided on the guide area larger than the cover body positioning hole 265a in such a position that the cover body positioning hole 265a is not in contact with the peripheral edge of the guide area. If the width dimension of the guide region between the cover body positioning hole 265a and the inner side surface G2 is formed at a position shorter than the outer diameter L5 of the positioning boss 312a, it is mounted on the bottom surface G1. If the placed positioning boss 312a is pushed into contact with the inner surface G2 on the opposite side of the cover body positioning hole 265a, a part of the positioning boss 312a is surely inserted into the cover body positioning hole 265a. Therefore, it can be easily fitted.

  In the present embodiment, since the inner side surface G2 standing on the periphery of the cover body positioning hole 265a stands on the periphery of the guide region, the positioning boss 312a placed on the bottom surface G1 is provided. If it is pushed so as to contact the inner surface G2 on the opposite side of the cover body positioning hole 265a, a part of the positioning boss 312a is surely engaged with the cover body positioning hole 265a so that it can be easily fitted. Can be made.

  Further, in this embodiment, the bottom surface G1 is formed in a band shape, and the inner side surfaces G2 and G2 constituting a pair of left and right wall surfaces extending in the longitudinal direction of the bottom surface G1 so as to face each other with the bottom surface G1 interposed therebetween. The positioning boss 312a placed on the bottom surface G1 is guided toward the cover body positioning hole 265a while being sandwiched between the pair of left and right inner surfaces G2 and G2. Can be combined.

  Further, the pair of left and right inner side surfaces G2, G2 are arranged so that the width dimension gradually becomes shorter toward the cover body positioning hole 265a, so that the positioning boss 312a has a wide portion on the bottom surface G1. After that, by simply sliding it toward the cover body positioning hole 265a, the lateral displacement of the positioning boss 312a with respect to the cover body positioning hole 265a is gradually reduced. It can be reliably inserted into 265a.

  Further, by providing the guide concave groove 266a corresponding to one of the plurality of cover body positioning holes 265a, it is possible not only to accurately position the gaming component unit 300 at a plurality of locations, but also among the plurality of guide concave grooves 265a. If the positioning boss 312a is securely fitted into the cover body positioning hole 265a provided with the groove 266a, the fitting position between the other cover body positioning hole 265b and the positioning boss 312b is determined and fitted. Therefore, the plurality of cover body positioning holes 265b and the positioning bosses 312b can be easily fitted.

  In the present embodiment, the bottom surface G1 is horizontally disposed toward the cover body positioning holes 265a to 265d. However, the bottom surface G1 of the guide grooves 266a to 266d faces the cover body positioning holes 265a to 265d. If the inclined surface is gradually inclined downward, the positioning bosses 312a to 312d loaded with the cover 302 can be gradually lowered while sliding on the bottom surface G1 of the guide grooves 266a to 266d. Since the drop at the time of fitting into the body positioning holes 265a to 265d can be gradually reduced, a large impact is generated at the time of fitting, and the gaming parts assembled in the cover body 302 break down, the spacer member 250, It is possible to prevent the cover body 302 from being damaged.

  Further, in this embodiment, guide grooves 266a to 266d that are recessed in the back surface 250b of the back plate 252 are used as guide portions for guiding the positioning bosses 312a to 312d to the cover body positioning holes 265a to 265d. However, the guide portion is not limited to such a concave groove, and although not particularly illustrated, for example, a bottom surface G1 formed on the back surface 250b of the spacer member 250 and a back surface 250b of the spacer member 250 are provided. You may comprise from the inner surface G2 comprised by the rib member etc. which were provided so that the bottom face G1 might be enclosed.

  Further, in this embodiment, the substantially U-shaped inner side surfaces G2 and G2 in plan view, which are continuous over the periphery of the guide region including the opening of the cover body positioning hole 265a and the bottom surface G1, are formed. If formed so as to surround, for example, the inner surface G2 may be disposed so as to be opposed to both sides in the width direction with the bottom surface G1 interposed therebetween, or is disposed in an annular shape so as to surround the entire circumference of the guide region. Alternatively, a plurality of inner side surfaces G2 may be arranged along the periphery of the guide region, that is, along the opening of the cover body positioning hole 265a or the periphery of the bottom surface G1.

  Further, in this embodiment, the bottom surface G1 of the guide grooves 266a to 266d is constituted by a belt-like surface extending from the opening edge of each cover body positioning hole 265a to 265d. As long as the area is larger than the openings 265a to 265d, the shape is not limited to the band shape, and may be formed in a circular shape or a polygonal shape, for example.

  Further, in the present embodiment, the cover body positioning holes 265a to 265d are formed on one end side in the longitudinal direction of the belt-like bottom surface G1, but may be formed, for example, in the central portion in the longitudinal direction. Further, the width of the cover body positioning holes 265a to 265d on the bottom surface G1 is the same as the inner diameters L1 and L2 of the cover body positioning holes 265a to 265d, but the cover body positioning holes 265a to 265d are formed. It may be larger than the inner diameters L1 and L2, and the bottom surface G1 may be formed to expand around the openings of the cover body positioning holes 265a to 265d.

  That is, the cover body positioning holes 265a to 265d may be formed at positions away from the periphery of the guide area in the guide area larger than the inner diameters L1 and L2 of the cover body positioning holes 265a to 265d. In this case, the inner side surface G2 only has a function of restricting contact so that the positioning bosses 312a to 312d do not deviate from the bottom surface G1.

  In the present embodiment, the guide grooves 266a to 266d are formed in a cross-sectional groove shape by the bottom surface G1 and the inner surface G2, but for example, the cross-sectional shape is a substantially upward U-shaped or substantially upward V-shaped groove. Or you may be comprised by the recessed part.

  In this embodiment, the pair of large and small cover body positioning holes 265a and 265b and the cover body positioning holes 265c and 265d are provided on the upper and lower sides, respectively, so that the operator is positioned on the lower side of the game board 6. In addition to being able to perform positioning from the upper cover body positioning holes 265a and 265b, the operator is positioned on the upper side of the game board 6 and performs positioning from the lower cover body positioning holes 265c and 265d. Can do.

  That is, the difference dimension L14 (L1-L5) between the inner diameter L1 of the cover body positioning holes 265a and 265d and the outer diameter L5 of the positioning bosses 312a and 312d is equal to the inner diameter L2 of the cover body positioning holes 265b and 265c. The clearance width dimension is larger than the positioning boss 312b and the cover positioning hole 265b by larger than the difference dimension (L2-L5) from the outer diameter L5 of the bosses 312b, 312c (L1-L5> L2-L5). If the positioning boss 312a is inserted into the cover body positioning hole 265a first, the positioning position of the positioning boss 312b with respect to the cover body positioning hole 265b is roughly determined and can be easily fitted. The game component unit 300 can be inserted into the cover body positioning hole 265a as a foothold. Even if there is, or if weight hearing, it is possible to perform the determination of the mounting position of the game component unit 300 on the game board 6 very easily.

  In this embodiment, the difference between the inner diameter L1 of the cover body positioning holes 265a and 265d and the outer diameter L5 of the positioning bosses 312a and 312d is the difference between the inner diameter L2 of the cover body positioning holes 265b and 265c and the positioning boss 312b. The difference between the inner diameter L2 of the cover body positioning holes 265b and 265c and the outer diameter L5 of the positioning bosses 312b and 312c is larger than the difference between the outer diameter L5 of the cover body positioning holes 265a and 265d. The difference may be greater than the difference between the inner diameter L1 and the outer diameter L5 of the positioning bosses 312a and 312d (L2-L5> L1-L5).

  Further, a plurality of positioning bosses 312b and 312c are fitted into the cover body positioning holes 265b and 265c with respect to the one positioning boss 312a and the cover body positioning hole 265a. The mounting position of the component unit 300 can be determined with certainty. Further, a plurality of positioning bosses 312b and 312c are fitted into the cover body positioning holes 265b and 265c with respect to the one positioning boss 312d and the cover body positioning hole 265d. The mounting position of the component unit 300 can be determined with certainty.

  Further, since the cover body positioning holes 265a and 265d having a larger diameter than the others among the plurality of cover body positioning holes 265a to 265d are formed in the bottom surface G1 of the guide grooves 266a and 266d, the cover body positioning holes The operation of fitting the positioning bosses 312a and 312d to the 265a and 265d can be performed more easily.

  In the present embodiment, as shown in FIG. 35A, the left cover body positioning hole 265b as the second recess is positioned as the right first recess serving as a reference for positioning. The hole 265a is disposed so as to be separated by an intermediate separation width dimension L11 between the minimum width dimension L12 (L10-L14) and the maximum width dimension L13 (= L10). For example, as shown in FIG. Thus, from the separation width dimension L10 between the positioning boss 312a as the first convex part and the positioning boss 312b as the second convex part, the inner diameter (width dimension) L1 of the cover body positioning hole 265a and the positioning boss 312a. May be arranged separated by a minimum width dimension L12 obtained by subtracting a difference dimension L14 (= L1-L5) from the outer diameter (width dimension) of the outer diameter (width dimension). In this case, the positioning boss 312a is Since the fitting position of the positioning boss 312b with respect to the cover body positioning hole 265b is determined by making contact with the inner surface of the bar body positioning hole 265a opposite to the cover body positioning hole 265b, the fitting work is easy. In addition, the backlash of the positioning boss 312a around the positioning boss 312b in the cover body positioning hole 265a is suppressed, so that the positioning can be performed more accurately.

  Further, as shown in FIG. 35 (c), the cover body positioning hole 265b is separated from the cover body positioning hole 265a by a maximum width dimension L13 (= L10) which is the same as the separation width dimension L10. In this case, the positioning boss 312a is brought into contact with the inner surface of the cover body positioning hole 265a on the cover body positioning hole 265b side, so that the positioning boss 312b for the cover body is provided. Since the fitting position with respect to the positioning hole 265b is determined, not only the fitting work is facilitated, but also rattling of the positioning boss 312a around the positioning boss 312b in the cover body positioning hole 265a is suppressed. Therefore, it can position more correctly.

  In the present embodiment, of the four cover body positioning holes 265a to 265d, the inner diameters of the two cover body positioning holes 265a and 265d are larger than the inner diameters of the other cover body positioning holes 265b and 265c. However, it is only necessary that at least one of the plurality has a larger diameter than the other cover body positioning holes.

  In this embodiment, the outer diameter L5 of all the positioning bosses 312a to 312d is the same, and the inner diameter L1 of the two cover body positioning holes 265a and 265d is the inner diameter of the other cover body positioning holes 265b and 265c. By making the diameter larger than L2, the difference between the inner diameter L1 of the cover body positioning holes 265a and 265d and the outer diameter L5 of the positioning bosses 312a and 312d is different from the inner diameter L2 of the cover body positioning holes 265b and 265c. The difference between the positioning bosses 312b and 312c and the outer diameter L5 is larger (L1-L5> L2-L5). For example, all the cover body positioning holes 265a to 265d have the same inner diameter (L1 = L2) Any one of the positioning bosses 312a to 312d may have an outer diameter larger than the others.

  Further, even when the inner diameters L1 and L2 of all the cover body positioning holes 265a to 265d and the outer diameter L5 of all the positioning bosses 312a to 312d are different, the inner diameter of the at least one cover body positioning hole and the positioning body If the difference from the outer diameter L5 of the boss is larger than the difference between the inner diameter of the other cover body positioning hole and the outer diameter of the positioning boss, the same operations and effects as described above are achieved.

  Further, if the positioning bosses 312a to 312d are formed in a tapered shape so that the diameter gradually decreases toward the tip, the cover body positioning holes 265a to 265d can be fitted into the cover body positioning holes 265a to 265d. The difference between the inner diameter of the positioning boss and the outer diameter of the positioning boss makes it easier to fit, and after fitting, the difference between the inner diameter of the back side opening in the cover body positioning hole and the outer diameter of the positioning boss Can be accurately positioned with respect to the spacer member 250.

  Further, in the present embodiment, the cover body positioning holes 265a to 265d are formed through the spacer member 250, and the front surface of the cover body positioning holes 265a to 265d is formed by the back surface 200b of the panel board 200 disposed on the front surface 250a. However, the cover body positioning holes 265a to 265d are provided with through holes at the positions corresponding to the cover body positioning holes 265a to 265d, and the cover body positioning holes 265a to 265d are formed. May be a through hole.
