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

First, the display content of the special symbol performed by the first special symbol display device 371B and the second special symbol display device 371D will be described. The variation display of the special symbol is expressed by the change of the lighting pattern of the eight LED segments. This special symbol variation display is based on the winning order of the game ball to the start winning device 33, based on the winning order, the first special symbol display device 371B.
And the second special symbol display device 371D, and stops after a predetermined time. Specifically, after performing the all-extinguishing process to stop the lighting state of the corresponding special symbol display device on the corresponding side, the change is started by executing the switching process of sequentially lighting each LED segment in a predetermined order, When the variable display time determined by the value of the stop pattern selection counter C3 described later elapses, the switching process described above is interrupted and the all-off process is performed, and determined based on the values of the jackpot random number counter C1 and the jackpot symbol counter C2 described later. Each LED segment is turned on according to the mode, and when displaying the result of losing in the jackpot lottery, only one dot-shaped LED segment is lit up, while when displaying the jackpot result Depending on whether or not the winning is to generate a high-probability gaming state after the jackpot, different numbers are arranged in the shape of “8” 7 Lit display using LED segments. Note that during the period when one special symbol display device is in the variable display state, the other special symbol display device does not perform the variable display, and the lighting display of the symbol that has been stopped and displayed when the last variable display is performed is continued. The The number of times that a game ball has won the central start port 33a and the right start port 33b of the start winning device 33 is held up to 4 times, respectively, and the number of hold times is about the number of holds corresponding to winning in the central start port 33a. The second special symbol hold display device 371C and the decorative symbol display device are displayed in the predetermined areas of the first special symbol hold display device 371A and the decorative symbol display device 42, respectively, and the number of holds corresponding to the winning at the right start port 33b. 42 in addition to the number of times of holding corresponding to winning in the central starting port 33a, depending on the gaming state, on the holding lamp 800a of the decorative symbol holding display device 800. The number of times of holding corresponding to winning in the right start opening 33b is lit up.

Next, display contents of the decorative symbol display device 42 will be described. On the display screen of the decorative symbol display device 42, for example, three decorative symbol columns Z1 to Z3 are displayed in three display areas divided into an upper stage, a middle stage, and a lower stage. These decorative symbol rows Z1 to Z3 are scroll-displayed from right to left. The decorative symbol is composed of, for example, a main symbol composed of numbers “1” to “9” and a sub symbol smaller than the main symbol, and a symbol row of the decorative symbol is formed by each of the main symbol and the sub symbol. In each symbol row formed with decorative symbols, the main symbols are arranged in ascending or descending order of numbers, and sub-designs are arranged between the main symbols. When a winning to the start winning device 33, that is, a start winning occurs, the decorative symbol is displayed in a variable manner, and the variable display is stopped after a lapse of a certain time according to the changing pattern. 3 nine decorative symbols are displayed as a display result. In the variable display won in the big win lottery, the display control device 45 controls the three main symbols so that they stop on a vertical or diagonal straight line among the nine decorative symbols. The jackpot is indicated. On the other hand, in the variable display out of the big hit lottery, the display control device 45 controls the game so that three identical main symbols do not stop vertically or diagonally among the nine decorative symbols. The occurrence of detachment is shown to the person. When the gaming state does not include a support state (a state in which the pair of opening and closing blades 60 is easier to open than usual and the opening time is longer than normal), the holding lamp 800a of the decorative symbol holding display device 800 is used. When the number of holds corresponding to the winning at the central start port 33a is lit and displayed with red light emission, the right start port is displayed on the hold lamp 800a of the decorative symbol display device 800 when the game state includes a support state. 33
The number of holdings corresponding to winning a prize for b is lit up.

Next, the display contents of the normal symbol performed in the normal symbol display device 371E will be described. The normal symbol variation display is expressed by alternately lighting the two LEDs described above. The variation display of the normal symbol is started on the condition that the game ball passes through the passing port of the operation winning device 34, and the variation display of the normal symbol is stopped after a predetermined time. And both LE
When D is stopped in a lighting state, the start winning device 33 is configured to be in an operating state for a predetermined time (the pair of opening / closing blades 60 are opened). The number of times that the game ball has passed through the opening of the operation winning device 34 is held up to 4 times, and the number of times of holding is the normal symbol hold display device 371F.
Is lit and displayed.
(When power is turned on)
When the power of the pachinko machine 10 is turned on, various parts such as a speaker, a liquid crystal screen of the decorative symbol display device 42, various LEDs arranged on the frame, various LEDs arranged on the game board 30 are specified as operation confirmation and power-on notification. It is set to perform a predetermined operation over a period of time (in this embodiment, 30 seconds). For this reason, it can be visually confirmed whether or not each of these parts functions normally. At this time, it can also be confirmed whether or not the pachinko machine 10 has been illegally modified.
Next, the operation of the pachinko machine 10 configured as described above will be described. In the present embodiment, the MPU 501 in the main control device 261 uses various counter information during the game to set up a jackpot lottery or a symbol display setting of a special symbol display device. Specifically, a counter group related to the special symbol and a counter group related to the normal symbol are provided. First, a counter group related to special symbols will be described. As a group of counters related to the special symbol, the jackpot random number counter C1 used for the jackpot lottery, the jackpot symbol counter C2 used for the selection of the jackpot symbol of the special symbol display device, and the special symbol display device when the special symbol display device is out and fluctuates. A stop pattern selection counter C3 used for selection of stop patterns (corresponding to reach lottery for reaching or completely losing in the variation of decorative symbols) and a jackpot random number counter C
1 includes an initial value random number counter CINI1 used for setting an initial value of 1, and variation type counters CS1 to CS3 for determining a type used for variation pattern selection.

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

Each of the counters C1 to C3, CINI1, CS1 to CS3 is a loop counter that adds 1 to the previous value every time it is updated, and returns to 0 after reaching the maximum value. Each counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area 700 including one execution area and four holding areas (holding first to fourth areas). In each of these areas, a game to the start winning device 33 is performed. The values of the jackpot random number counter C1, the jackpot symbol counter C2, and the stop pattern selection counter C3 are stored in accordance with the winning timing of the ball.

  Next, the specific contents of each counter will be described in detail.

The jackpot random number counter C1 is configured such that, for example, 1 is sequentially added within a range of 0 to 738, and after reaching the maximum value (that is, 738), it returns to 0. Especially jackpot random number counter C
When 1 makes one round, the value of the random number initial value counter CINI1 at that time is read as the initial value of the jackpot random number counter C1. The random number initial value counter CINI1 is configured as a loop counter that is updated in the same range as the jackpot random number counter C1 (value = 0 to 0).
738), and is updated once for each timer interrupt and is repeatedly updated within the remaining time of the normal processing. The jackpot random number counter C1 is updated periodically (once every timer interruption in this embodiment), and the reserved ball storage area 7 of the RAM 503 is the timing when the game ball wins the start winning device 33.
Stored in 00. The number of random number values that are jackpots is set at two times, low probability and high probability. The number of random number values that are jackpots at low probability is 2, and the value is “373,727”.
”And the number of random number values that are jackpots at high probability is 14, and the values are“ 59, 109,
163, 211, 263, 317, 367, 421, 479, 523, 577, 631,
683,733 ". High probability means a state in which a special symbol combination is a jackpot due to the combination of a specific symbol that is a predetermined probability variation symbol and the subsequent jackpot probability has increased as added value, so-called probability change. Time (when the probability is low) refers to a case where the probability variation state is not such.

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

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

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

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

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

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

The variation type counter CS1 is, for example, incremented by 1 within a range of 0 to 198, and returns to 0 after reaching the maximum value (that is, 198). The variation type counter CS2 is, for example, incremented by 1 within a range of 0 to 240, and returns to 0 after reaching the maximum value (that is, 240). The variation type counter CS3 is, for example, 1 in order within a range of 0 to 162, for example.
Each is added, and after reaching the maximum value (that is, 162), it returns to 0.

The variation type counter CS1 determines a rough pattern variation mode such as the type of reach such as normal reach, super reach, special reach, premium reach, etc., and the variation type counter CS2 further determines, for example, normal reach A, normal reach B, etc. The detailed symbol variation mode is determined, and the variation type counter CS2 determines, for example, the addition / subtraction of the variation time in the case of the slip stop variation. Therefore, these variation type counters CS
By combining 1 to CS3, a wide variety of variation patterns can be easily realized.

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

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

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

Next, the specific contents of the winning random number counter C4 and the initial value random number CINI2 will be described in detail. The winning random number counter C4 is, for example, incremented by 1 in the range of 0 to 250, and returns to 0 after reaching the maximum value (that is, 250). When the winning random number counter C4 makes one round, the value of the winning initial value random number counter CINI2 at that time is read as the initial value of the winning random number counter C4. The initial value random number counter CINI2
Is configured as a loop counter that is updated in the same range as the hit random number counter C4 (value =
0 to 250), it is updated once every timer interrupt and is repeatedly updated within the remaining time of the normal processing. The winning random number counter C4 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area 701 of the RAM 503 at the timing when the game ball passes through the operation winning device 34. The number of random number values hit by the hit random number counter C4 is 149,
The value is “5 to 153”.

In addition, the magnitude | size and range of each counter are only examples, and can be changed arbitrarily. However, if importance is attached to irregularity, the big hit random number counter C1, stop pattern selection counter C3, hit random number counter C4, and variation type counters CS1 to CS3 are all different prime numbers and are not synchronized in any case. It is desirable to leave.
The details of each control process executed by the MPU 501 in the main controller 261 are as follows.
Detailed description is omitted here.

However, in summary, as described above, the main control device 2 is obtained by winning the start winning device 33.

As a result, the movable hook 72 moves away from the first face plate 74 of the base 71 by the locking portion 72H (clockwise direction as shown by arrow A11 in FIG. 16).
It has come to be energized.

A lock member 84 is mounted between the movable hook 72 and the second face plate 75 of the base 71.
As shown in FIG. 21, the lock member 84 extends in a substantially rectangular shape that fits in the base 71 corresponding to the outer shape (rectangle) of the second face plate 75 of the base 71, and has one end edge (the left lower end edge in FIG. 21). Further, both side edges thereof have a shape extending in a circumferential wall shape having a U-shaped cross section toward one surface side (the upper surface side in FIG. 21), and are made of the same resin as that constituting the movable hook 72 described above. Yes. A plurality of ribs extending along the extending direction project from the outer surfaces of both side pieces of the peripheral wall-shaped extending portion to form a gripping surface 84G. A regulating surface 84L perpendicular to the extending direction of the peripheral wall-shaped extension portion is formed at a position slightly inward (slightly below the upper end in FIG. 21) on the inner side of the peripheral wall-shaped extension portion. From the restricting surface 84L, the other end side of the lock member 84 (FIG. 2).
In FIG. 1, a sloped guide surface 84 </ b> S in which the height in the extending direction of the peripheral wall-shaped extending portion gradually decreases is formed. Both sides of the guide surface 84S are continuous with both side pieces of the peripheral wall-like extension portion. The peripheral wall-shaped extending portion, the regulating surface 84L, the guide surface 84S, and the like are all formed into a wall shape having a predetermined thickness and are integrally continuous at the boundary portion. With the above configuration, one end portion (the lower left end portion in FIG. 21) of the lock member 84 is formed into a generally trapezoidal shape toward one surface side (upper surface side in FIG. 21) and bulging into a hollow shape. Has been. As shown in FIG. 17, the side surface opposite to the regulating surface 84L (see FIGS. 17 and 21) in the bulging portion.
In the bulging portion, a partition wall 84P parallel to the end surface of the bulging portion (the left front end surface in FIGS. 17 and 21) is located at the boundary between the regulating surface 84L and the guide surface 84S. The partition 84P is formed, and the space in the bulging portion has a shape partitioned into a substantially rectangular parallelepiped space inside the regulating surface 84L and a substantially triangular prism shaped space inside the guide surface 84S. .

As shown in FIG. 21, in the lock member 84, the peripheral edge of the portion extending from the substantially trapezoidal bulge portion to the other end side (upper right end side in FIG. 21) is the extension height of the peripheral wall-like extension portion. It is formed into a peripheral wall shape having an extension height smaller than the above, and has a generally rectangular dish shape thinner than the bulging portion as a whole. In other words, a recess 84N that is recessed in a substantially rectangular dish shape is formed so as to be surrounded by the peripheral wall-shaped portion and the guide surface 84S. Inner rails 84R extend from both ends of the peripheral wall-shaped portion to both sides. The inner rail 84R extends linearly from the recess 84N side end (upper right side end in FIG. 21) of the lock member 84 to the vicinity of the gripping surface 84G. On both sides of the recess 84N, a regulation rib 84M is formed at the lower part of the inner rail 84R.

As shown in FIG. 18, the lock member 84 is placed on the second face plate 75 of the base 71 with a surface (the lower surface in FIG. 18) opposite to the substantially trapezoidal bulge forming side. Then, it is inserted into the base 71 from the concave portion 84N side. At this time, the inner rail 84 </ b> R of the lock member 84 is connected to the base 71.
The outer rails 76R, 77R of the inner side (the lower side in FIG. 18) enter the inside of the outer rails 76R, 77R.
4 is held so as to be slidable along the length direction (lower left or upper right in FIG. 18) on the second face plate 75 while being restricted from moving up and down. At this time, while the lock member 84 is being inserted, the restriction rib 84M comes into contact with the restriction rib (not shown) of the base 71, but the third face plate 76 and the fourth face plate 77 are forcibly press-fitted while being elastically deformed. To do. After the press-fitting, the movement of the restriction rib 84M of the lock member 84 is restricted by the restriction rib of the base 71, thereby restricting the lock member 84 from being pulled out from the base 71 beyond a predetermined distance.

As shown in FIG. 22, the pusher 73 extends in a generally rectangular shape (generally strip shape) in a front view that fits in the base 71 corresponding to the outer shape (rectangle) of the first face plate 74 of the base 71, and is generally half on one end side. While the portion (the upper half on the upper side in FIG. 21) bulges to one surface side (the lower left side in FIG. 21) in the thickness direction,
The other end half (the lower end half in FIG. 21) is slightly recessed in the thickness direction to form a curved surface meandering in a generally S-shape when viewed from the side, and on both sides of the curved surface. Each has a substantially cloud-shaped side wall perpendicular to the curved surface, and is made of the same resin as that of the movable hook 72 described above. A pressing surface 73E is formed by the bulging curved surface of the one end side half. The inner side (FIG. 21) of the pressing surface 73E forming side end (upper end in FIG. 21).
In the center of the width direction on the back side, a partition parallel to the side wall is formed (not shown).
Further, the central portion in the length direction on the inside and the end portion on the side opposite to the pressing surface 73E formation side (FIG. 2).
1 is formed with ribs extending in the width direction (not shown). A shaft insertion opening 73P penetrating in a straight line in the width direction of the pusher 73 is formed in the both side walls and the partition wall.

As shown in FIG. 18, the pusher 73 has the shaft insertion opening 73 </ b> P formation side end (upper end in FIG. 18) directed toward the fifth face plate 78 side of the base 71, and the opposite side of the pressing surface 73 </ b> E is the first side of the base 71. 1
It is housed in the base 71 with the posture facing the face plate 74, and the shaft insertion opening 73 </ b> P is connected to the third face plate 7.
6 and the second pivot shaft 85 in a state matched with the second shaft insertion holes 76S and 77S of the fourth face plate 77.
Is inserted and fixed on the outer surface side of each of the third face plate 76 and the fourth face plate 77 with an E-type retaining ring (not shown) so as to be pivotally supported. A second torsion coil spring 86 is fitted inside the pusher 73. The second torsion coil spring 86 includes two coils 86C,
This is a double torsion spring integrally having a U-shaped central arm 86M between the two coils 86C and end arms 86E extending further on both sides of the two coils 86C. As shown in FIG. 17, the second torsion coil spring 86 is connected to the end portion of the pusher 73 on the side where the pressing surface 73E is formed (
17 and 18, the central arm 8 is positioned on the inner side (the back side in FIGS. 17 and 18) with the partition wall between the coils 86 </ b> C and the position of the shaft insertion opening (not shown).
6M is the end side direction opposite to the press surface 73E forming side end of the pusher 73 (FIGS. 17 and 1).
8 is a downward direction) and is directed obliquely away from the pusher 73, that is, toward the lower right direction in FIGS. 17 and 18, while the end arm 86E is opposite to the end portion of the pusher 73 on the side where the pressing surface 73E is formed. It is arranged so as to face the part side direction (downward in FIGS. 17 and 18) and gradually toward the back surface of the pressing surface 73E, that is, in the lower left direction in FIGS. 17 and 18, and as described above. On the way of inserting the moving shaft 85, the coil 86C is inserted along with both the coils 86C, so that it is fitted on the second rotating shaft 85. The tip of the central arm 86M of the second torsion coil spring 86 contacts the first face plate 74 of the base 71, while the tip of the end arm 86E extends in the direction extending along the back surface of the pressing surface 73E of the pusher 73 (FIG. 17 and FIG. In FIG. 18, it is bent in the downward direction), and the bent portion is disposed so as to contact the back surface of the pressing surface 73E. As a result, the pusher 73 moves toward the locking portion 72H of the movable hook 72 with the one end portion pivotally supported by the second rotation shaft 85 (in FIG. 16, as shown by the arrow A12 in the counterclockwise direction). Rotation direction).

As schematically shown in FIG. 9, the first hooking device 70 </ b> A has the third face plate 76 and the fourth face plate 77 of the base 71 on the upper side and the lower side, and the second face plate 75 and the fifth face plate 78 on the right side and On the left side
The first face plate 74 is disposed on the front surface of the inner frame 12 with the posture facing the rear side, and is fastened and fixed by screws at the screw insertion pieces 74T of the base 71.

Hereinafter, a procedure for attaching the game board 30 using the first hooking device 70A will be sequentially described.
(A) Usually, as shown in FIGS. 23 and 24, the movable hook 72 of the first hooking device 70A is set to the closed position before the mounting operation. If the movable hook 72 and the lock member 84 are protruded forward, it becomes easier to receive contact from the surroundings, and it is more likely to be damaged.
In addition, since it tends to interfere with surrounding work, it is desirable to store (retract) the movable hook 72 and the lock member 84 in this way.

In the closed position, as shown in FIG. 24, the right side surface of the rotating body portion 72 </ b> D of the movable hook 72 abuts on the restriction surface 84 </ b> L of the lock member 84, thereby the locking portion 72 of the movable hook 72.
H is restricted so that it cannot rotate in a direction away from the board surface of the game board 30 (counterclockwise direction in FIG. 24). That is, the movable hook 72 is locked at the closed position by the lock member 84.

On the other hand, as shown in FIGS. 9 and 23, a fixing hook 87 is arranged and fixed at a position corresponding to the center of the left side edge of the game board 30 in the height direction on the front surface of the inner frame 12.
The fixed hook 87 is a member that has a substantially U-shaped cross section that can include the left side edge of the game board 30 and extends slightly longer in the vertical direction. Although not shown in FIG. 9, as shown in FIG. 23, the ridge corner of the front side piece 87F of the fixed hook 87 is formed such that the ridge corner portion on the inner side of the front end (upper right side in FIG. 23) falls, and thereby the game board 30 is easily received. On the other hand, a pressing piece 88 for pressing the game board 30 from the rear to the front is disposed on the rear piece 87R. The configuration and mounting structure of the pressing piece 88 are the same as those of the pusher 73 in the first hooking device 70A described above, and therefore the description thereof is omitted. The fixed hook 87 is the first hooking device 70 described above.
While the movable hook 72 in A is configured to be movable, it is a non-movable (non-movable) hook member that always maintains a substantially U-shaped cross section except for the operation of the pressing piece 88.
(B) At the time of attachment work, first, as shown by an arrow A13 in FIGS. 23 and 24, the lock member 84 of the first hooking device 70A is pulled out to the front of the pachinko machine 10, thereby showing in FIGS. 25 and 26. As described above, the movable hook 72 is set to the open position. The lock member 84 can be gripped so as to pinch the gripping surface 84G and can be easily slid out. FIG.
5 and FIG. 26, when the entire gripping surface 84G reaches a position slightly protruding forward from the base 71, the movement of the restriction rib 84M of the lock member 84 is restricted by the restriction rib of the base 71 as described above. As a result, the lock member 84 is regulated so that it cannot be pulled forward from this position. That is, this position is a limit position for moving the lock member 84 forward. As the lock member 84 is pulled forward to the movement limit position in this way, the restricting surface 84L is disengaged from the rotating body 72D of the movable hook 72 to release the restriction of the operation of the movable hook 72. Since the movable hook 72 is urged by the first torsion coil spring 83, the urging force causes the movable hook 72 to move forward as shown by an arrow A14 in FIGS. 25 and 26 (in FIGS. 25 and 26). Turn counterclockwise. At this time, in the movable hook 72, the curved surface of the protruding corner in the bent portion rotates along the guide surface 84S of the lock member 84. When the movable hook 72 is turned forward by about 45 ° from the closed position as shown in FIGS.
The right side surface of 2D hits the front surface of the right side portion (recessed portion) of the pusher 73, and further rotation is prevented. That is, this position is a limit position for turning the movable hook 72 forward and is an open position.
(C) Next, as shown in FIG. 27, while the gaming board 30 is tilted so that the right side is further away from the pachinko machine 10, the left side edge is inserted into the fixed hook 87 from the right front, and the front side Hang inside the piece 87F.
(D) Next, as shown by an arrow A15 in FIG. 27, the game board 30 is rotated so that the door is closed (counterclockwise in FIG. 27) around the above-mentioned left end edge latching position. FIG.
As shown in FIG. 4, the right end is inserted to a position where it abuts against the pusher 73 of the first hooking device 70A.

At this time, the ridge corner on the left rear side of the game board 30 comes into contact with the pressing piece 88 of the fixed hook 87 and receives a slight resistance, but by turning the game board 30, a large lever force acts on the ridge corner. Therefore, the left edge of the game board 30 is connected to the front piece 87F and the rear piece 87R in the fixed hook 87 as shown in FIG.
Insert between. After the left edge of the game board 30 is thus fitted into the fixed hook 87, the pressing piece 88 elastically presses the game board 30 against the front piece 87F of the fixed hook 87 from the rear, so that the left edge of the game board 30 The front surface is always held at the position of the inner side surface of the front piece 87F of the fixed hook 87. With this configuration, even if the board thickness of the game board 30 varies, the front surface of the left end portion of the game board 30 is reliably held at a predetermined position. In other words, the pressing piece 8
Due to the elasticity of 8, the front surface of the game board 30 can be accurately fitted to a predetermined front-rear position while absorbing variations in plate thickness.

On the other hand, in the first hooking device 70A, since the movable hook 72 is set at the open position, the right end of the game board 30 can be easily fitted. At this time, instead of the first hooking device 70A, for example, a hooking device (hereinafter also referred to as “reference hooking device”) 89 having a configuration schematically shown in FIG. 29 may be used. However, according to this reference latching device 89,
There is a disadvantage compared to the first hooking device 70A described above. In the reference latch device 89 shown in the figure, the movable hook 90 has a substantially U-shaped cross section that can include the right side edge of the game board 30. When the game board 30 is attached or detached, As shown in FIG. 29, the movable hook 90 is rotated obliquely forward and set at the open position. In this configuration, the portion that contacts the front surface of the game board 30 and the portion that contacts the rear surface are integrated with a substantially U-shaped cross section, so the number of components is small and the configuration is simple. There are advantages. However, the space for receiving the game board 30 in the movable hook 90, that is, the distance between the front and rear side pieces is always a constant dimension that is almost equal to the thickness of the game board 30 and does not expand further. It is difficult to insert the game board 30. Further, since the elastic force of the pusher 91 is immediately received from the time when the game board 30 is inserted, an extra force is required until the game board 30 is fitted to the mounting position. On the other hand, when the game board 30 is removed from the mounting position, the game board 30 is inevitably pulled forward together with the movable hook 90 being set to the open position. There is also a problem that there is a risk of falling vertically if not supported.

On the other hand, in the first hooking device 70 </ b> A, the pusher 73 is disposed at a certain rear (back) position along the front surface of the inner frame 12 regardless of the rotation (displacement) of the movable hook 72. Since it moves substantially back and forth for pressing, it is substantially immobile. Therefore, when the movable hook 72 is set to the open position, the space between the pusher 73 is greatly expanded and a space for receiving the game board 30 is obtained. Therefore, the game board 30 can be easily inserted. That is, the pusher 73 stays at a certain rear (back) position through the process until the game board 30 is inserted into the mounting position, and does not touch the game board 30, while FIG. 27 and FIG.
As shown in FIG. 3, the movable hook 72 in the open position deviates outside the turning track of the game board 30. Therefore, since the space between the game board 30 and the mounting position is completely open and there is no object to be touched, the game board 30 can be fitted into the mounting position very easily.
Further, since the pusher 73 does not come into contact with the game board 30 until it reaches the mounting position, no resistance is generated on the game board 30 in addition to the elastic force. On the other hand, when the game board 30 is removed from the attachment position, the movable hook 72 can be moved to the open position with the game board 30 left in the attachment position. Since the game board 30 is supported by the inner frame 12 at the mounting position, it is necessary to keep the game board 30 from falling forward only by removing the movable hook 72, but there is a risk of falling vertically. Therefore, it is probably safer than in the case of the reference latch device 89.
(E) Next, as shown in FIG. 30, the movable hook 72 of the first hooking device 70A is returned to the closed position again. At this time, as shown by an arrow A16 in FIG.
Push it back to zero. As the lock member 84 is pushed in in this way, the guide surface 84S of the lock member 84 functions as a cam surface, and the curved surface of the protruding corner at the bent portion of the movable hook 72 is shown by an arrow A17 in FIG. Then, the first torsion coil spring 83 is guided so as to rotate in the direction of retracting backward (clockwise in FIG. 30) against the urging force of the first torsion coil spring 83. Thus, when the movable hook 72 is rotated about 45 ° rearward from the open position, the right side surface of the rotating portion 72D of the movable hook 72 comes into contact again so as to ride on the regulating surface 84L of the lock member 84, thereby moving the movable hook 72. The hook 72 is locked (restricted) in the closed position again by the lock member 84.

At this time, the resistance is somewhat received by the elastic force of the pusher 73 via the game board 30.
By pushing the lock member 84 backward, the right end of the game board 30 can be inserted into the mounting position as shown in FIG. After the right edge of the game board 30 is thus fitted into the mounting position and the movable hook 72 of the first hooking device 70A is locked in the closed position, the pusher 73 is elastic as in the case of the left edge described above. The game board 30 is pressed against the locking portion 72H of the movable hook 72 from behind, while the locking portion 72H of the movable hook 72 is locked in the closed position and is held stationary. The front surface of the end is always the locking portion 7 of the movable hook 72.
It is held at the position of the inner surface of 2H. With this configuration, even if the board thickness of the game board 30 varies, the front surface of the right end portion of the game board 30 is reliably held at a predetermined position. In other words, due to the elasticity of the pusher 73, the front surface of the game board 30 can be attached to the predetermined front and rear position accurately while absorbing the thickness variation.

According to the above mounting process, as described above, even if the board thickness of the game board 30 varies, the left and right side ends of the game board 30 are fixed on the front surface by the fixing hook 87 and the first hooking device 70A, respectively. Although it is possible to attach the front and rear positions so as to be accurately aligned with a predetermined position, the game board 30 can be attached by using the fixing hook 87 and the first hooking device 70A, particularly the first hooking device 70A. This can be done advantageously.

In the first hooking device 70A, the movable hook 72 can be moved between the closed position and the open position by pushing and pulling out the lock member 84, so that the operation is easy. In particular, the lock member 84 is arranged separately from the movable hook 72 so that the game board 3
It can operate without touching the front surface of 0, and when pushing the game board 30 against the elastic force of the pusher 73, it is not necessary to push the game board 30 while directly contacting it. Further, damage such as scratches on the surface (front surface) of the game board 30, dirt, and the like can be reduced. Further, at this time, the movable hook 72 and the pusher 73 that are in contact with the game board 30 are made of resin, so that the damage to the game board 30 is further reduced. In addition, the base 71 and the lock member 84 are also combined. Since the entire first hooking device 70A is basically made of resin, the first hooking device 70A is light and inexpensive. Furthermore, the movable hook 72 is formed into a shape in which the corner portion inside the front end portion that easily contacts the game board 30 is dropped, while the pusher 73 has a curved surface shape in which the surface facing the game board 30 is gently expanded. Due to such a shape of the movable hook 72 and the pusher 73, damage to the game board 30 is reduced.

Further, since the movable hook 72 is rotated, the movable hook 72 is configured to move in a direction substantially orthogonal to the surface (front surface) of the game board 30 to come into contact with and separate from the game board 30. Damage to the surface of the surface (especially damage due to friction) is reduced.

In addition, both the movable hook 72 and the lock member 84 are configured to move and operate by rotating or reciprocating in the direction orthogonal to the game board 30, that is, the front-rear direction of the pachinko machine 10. The necessary area does not expand around the first hooking device 70A (that is, outwards along the board direction of the game board 30), and fits in the area corresponding to the front shape of the first hooking device 70A. It has become. For example, if the operation area is configured to expand to the surroundings by rotating or sliding the hooks or operating members, it is necessary to secure a free space for this operation around the area. If a vacant space is provided, there is a problem that an illegal act such as inserting a fraudulent tool into the pachinko machine 10 is likely to be performed. On the other hand, according to the configuration of the first hooking device 70A, there is no need to provide such an empty space in the surroundings, which is advantageous from the viewpoint of preventing fraud.
(Operation according to the first embodiment)
The pachinko machine 10 is configured by attaching a game board 30 having a game area on the front side where a game ball flows down to the inner frame 12 of the game machine main body from the front.
Is held in a posture that restricts the front and rear positions of the front surface of the game board 30 from the front when the game board 30 is in the attachment position, and the game board 30 when the game board 30 is in the attachment position. The movable hook 72 of the first hooking device 70A, which is a movable portion that can be displaced from the position of the front surface of the 30 and released to allow the game board 30 to be attached and detached, and the movable hook 72 Regardless of the displacement, the game board 30 is arranged at a certain front and rear position on the rear side of the game board 30, and
And a pusher 73 of the first hooking device 70 </ b> A, which is a pressing portion that presses forward.

According to the above configuration, the game board 30 can be easily moved into and out of the mounting position by moving the movable hook 72 to the open position, while the game board 30 can be easily moved by moving the movable hook 72 to the closed position. Can be fixed in the mounting position, and therefore the movable hook 7
The game board 30 can be easily attached and detached by the displacement of 2.

Further, since the pusher 73 is disposed at a fixed front and rear position regardless of the displacement of the movable hook 72, it is difficult to obstruct the game board 30 when it is attached or detached. At this time, if the pressing portion (pusher 91) moves forward as the movable portion (movable hook 90) is displaced to the open position, as in the case of the reference latch device 89, for example, Board 3
There is no expansion of the space for entering and exiting 0, and the pressing portion (pusher 91) is easily attached when the game board 30 is entered and exited, making it difficult for the game board 30 to enter and exit, and the game board 30 to be easily damaged. There is also a problem. On the other hand, according to the configuration of the pachinko machine 10, even if the movable hook 72 is displaced to the open position, the pusher 73 does not move forward and remains at a certain front and rear position. The pusher 73 is difficult to hold when the game board 30 is put in and out, so that the game board 30 can be easily put in and out and the game board 30 is unlikely to be damaged. It is also.

Further, the game board 30 arranged at the attachment position is regulated from the front and back by the movable hook 72 displaced to the closed position and is pushed forward by the pusher 73, so that the front surface of the game board 30 is closed. The movable hook 72 is pressed against the position and held at a predetermined front and rear position. Therefore, even if the board thickness of the game board 30 varies, the front face of the game board 30 is reliably and stably held at a predetermined front and rear position without being affected by this.

In addition, since it further includes a lock member 84 that is an operation unit that can operate without touching the front surface of the game board 30 and displace the movable hook 72, the movable hook 72 can be opened by operating the lock member 84. In addition, the game board 30 can be easily displaced to the closed position, so that the game board 30 can be attached and detached more easily.

At this time, the lock member 84 that is the operation unit can be operated without contacting the front surface of the game board 30, so that the movable hook 72 is displaced by operating with the lock member 84, thereby The game board 30 can be attached and detached without touching it, and therefore the appearance of the game board 30 can be maintained satisfactorily without damaging the front surface of the game board 30.

Further, since the movable hook 72 is configured to be able to change between the closed position and the open position by rotating, this also reduces damage to the surface of the game board 30 (particularly damage due to friction). ing.

In addition, since the movable hook 72 and the lock member 84 are configured to move and operate in the front-rear direction of the pachinko machine 10, the area necessary for the operation may expand outward along the board surface direction of the game board 30. There is no such thing. Therefore, it is not necessary to secure a vacant space for the operation around. That is, it is possible to avoid providing an extra space that can be easily used for fraudulent acts, which is desirable from the viewpoint of fraud prevention.

Further, since the movable hook 72 and the pusher 73 that are parts that come into contact with the game board 30 are made of resin, damage to the game board 30 is reduced.

Further, since the movable hook 72 and the pusher 73 together with the lock member 84 are mounted on the base 71 and are configured as the first hooking device 70A, the first hooking device 70A is used as the inner frame 1.
2, the movable hook 72 and the pusher 73 can be easily attached to the inner frame 1 at a time.
2 can be arranged.

Further, the first hooking device 70A basically has the whole (that is, the first and second rotating shafts 8).
The first and second torsion coil springs 83 and 86 (except for the first and second torsion coil springs 83 and 86 and the E-type retaining ring) are made of resin, so that the structure is light and inexpensive.

In addition, the pachinko machine 10 includes a game board 30 having a game area on the front where game balls flow down,
The gaming machine main body, that is, the inner frame 12 is attached to the inner frame 12 of the gaming machine main body from the front, and the gaming board 30 is held from the front when the gaming machine main body, that is, the inner frame 12 is in the mounting position. A movable portion that is displaceable between a closed position that is disabled and an open position that is disengaged from the position of the front surface of the game board 30 when it is in the attachment position and allows the game board 30 to be attached and detached; A lock member 84 of the first hooking device 70A, which is an operation unit that can move the movable hook 72 by moving without contacting the front surface of the game board 30; It is the composition provided with.

According to the above configuration, the game board 30 can be easily moved in and out of the mounting position by operating the lock member 84 that is an operation portion and displacing the movable hook 72 to the open position, while the movable hook 72 is closed. The game board 30 can be easily fixed at the mounting position by displacing the game board 30. Therefore, the game board 30 can be easily attached and detached by the displacement of the movable hook 72.

At this time, since the lock member 84 can be operated without contacting the front surface of the game board 30, the game board 3 can be operated by operating the lock member 84 to displace the movable hook 72.
The game board 30 can be attached and detached without touching the front surface of the 0, so that the game board 3
It is possible to maintain a good appearance without scratching or soiling the front surface of the zero.

Further, since the movable hook 72 is configured to be able to change between a closed position and an open position by rotating, damage to the surface of the game board 30 due to the movement of the movable hook 72 (
Especially damage due to friction is less.

In addition, since the movable hook 72 and the lock member 84 are configured to move and operate in the front-rear direction of the pachinko machine 10, the area necessary for the operation may expand outward along the board surface direction of the game board 30. There is no such thing. Therefore, it is not necessary to secure a vacant space for the operation around. That is, it is possible to avoid providing an extra space that can be easily used for fraudulent acts, which is desirable from the viewpoint of fraud prevention.

Moreover, since the movable hook 72 which is a site | part which contacts the game board 30 is comprised with resin,
Damage to the game board 30 is reduced.

In addition, the movable hook 72 and the lock member 84 are mounted on the base 71 and the first hooking device 7 is mounted.
Since the first hooking device 70A is attached to the inner frame 12, the movable hook 72 and the lock member 84 can be easily disposed on the inner frame 12 at a time. ing.

Further, the first hooking device 70A basically has the whole (that is, the first and second rotating shafts 8).
The first and second torsion coil springs 83 and 86 (except for the first and second torsion coil springs 83 and 86 and the E-type retaining ring) are made of resin, so that the structure is light and inexpensive.
2. Second Embodiment In the first embodiment, instead of the first hooking device 70A, for example, a hooking device according to a second embodiment as shown in FIGS. 31 to 39 (hereinafter referred to as “second hooking device”). 70B may also be used. The second hooking device 70B shown in FIG.
And the pusher 94 has a basic structure mounted. The base 92, the movable hook 93, and the pusher 94 are members molded using the same resin.

The base body 92 includes an outer body 921 shown in FIGS. 40 and 41 and an inner body 922 shown in FIGS. 42 and 43. As shown in FIGS. 40 and 41, the outer body 921 is
The rectangular flat plate-like first piece 92B having a slight thickness is perpendicular to the one side (the rear side in FIG. 40) from one end edge (the upper end edge in FIG. 40) of the rectangular flat plate-like first piece 92B. Second piece 9
2M extends, and from the extended edge of the second piece 92M, the side opposite to the first piece 92B side (FIG. 40).
In the vertical direction to the upper side), a rectangular flat plate-like third piece 92T having a slight thickness extends,
As a whole, it is a solid having a side surface shape that is bent at a right angle at two locations in a substantially zigzag shape. Each of the first piece 92B, the second piece 92M, and the third piece 92T is configured in a rectangular parallelepiped shape having a slightly smaller thickness in one direction, with three or four sides closed by plate-like walls, and is continuous with each other. The overall shape as described above is configured, and the second piece 92M side surface portion (FIG. 41) in the first piece 92B.
In FIG. 41, the left front side portion) and the front end surface portion (lower surface portion in FIG. 41), the first piece 9 in the second piece 92M.
2B side surface portion (lower surface portion in FIG. 41), third piece 92T side end surface portion (left front end surface portion in FIG. 41), and side surface portion opposite to the second piece 92M side in the third piece 92T (left front side surface portion in FIG. 41).
Both are fully open. That is, the outer body 921 is bent at a right angle in a substantially zigzag shape when viewed from the side, from the front end surface portion of the first piece 92B to the side surface portion (left front side surface portion in FIG. 41) opposite to the second piece 92M side of the third piece 92T. The continuous four surfaces are entirely open as a whole.

On the wall on the third piece 92T side in the thickness direction of the second piece 92M (the upper side wall in FIGS. 40 and 41), the center part at the boundary with the first piece 92B is moved inward along the second piece 92M. A hook insertion opening 92H extending in a rectangular shape is formed (up to the vicinity of the center of the wall). Further, on the wall on the first piece 92B side in the thickness direction of the third piece 92T (the front side wall in FIG. 40, the rear side wall in FIG. 41), the third piece 92T from the center at the boundary with the second piece 92M. Along the inner side (to a position slightly beyond the center of the wall), the wall on the third piece 92T side in the thickness direction of the second piece 92M, that is, the hook insertion opening 92H is formed. The wall extends from the central portion at the boundary with the third piece 92T toward the inside along the second piece 92M in a slightly shallow rectangular shape (slit shape), and as a whole, the second piece 92M extends from the boundary.
A pusher insertion opening 92P is formed along the direction of both of the third piece 92T. The pusher insertion opening 92P expands while communicating with the same width while being bent at a right angle at the boundary so as to form a substantially L shape in a side view. Yes. The width of the hook insertion opening 92H and the pusher insertion opening 92P (the dimension along the direction parallel to the boundary line between the first piece 92B, the second piece 92M, and the third piece 92T) is the same, and the entire outer body 921 The width is about 50% of the width.

From the inner side surface of the two continuous walls in which the hook insertion opening 92H and the pusher insertion opening 92P are formed, a side surface that is similar to the both side walls that are continuous in a zigzag shape in a side view in the outer body 921 and is slightly smaller than the side wall surfaces. An inner rib 92R having a shape extends vertically. As shown in FIG. 41, the inner rib 92R is located slightly inward (a position closer to the center of the first piece 92B) than the first protruding corner (lower right corner in FIG. 41) inside the first piece 92B. ) To a position slightly closer to the inner side (position closer to the center of the third piece 92T) than the first protruding corner (upper right corner in FIG. 41) inside the third piece 92T (see FIG. 41). 41 is extended in parallel to the right side surface at a distance from the one side surface, then bent at a right angle along the front end surface (upper end surface in FIG. 41) of the third piece 92T and extended to the other side. Furthermore, it extends from the tip to a position slightly closer to the inside (position closer to the center of the first piece 92B) than the other protruding corner (lower left corner in FIG. 41) of the tip inside the first piece 92B. The inner rib 92R as a whole has a dimension that is slightly smaller in both extension height and total extension than the both side walls and the third piece 92T side end wall of the outer body 921, and is substantially U-shaped in rear view. The hook insertion opening 92H and the pusher insertion opening 92P
The ribs extend so as to pass through both side edges (that is, in the widthwise central portion of the outer body 921 with the same width as the hook insertion opening 92H and the pusher insertion opening 92P). Further, at a plurality of locations on the inner surface of both side pieces and the center of the inner surface of the central piece in the inner rib 92R,

The sliding rib 92F reduces the frictional force by reducing the contact area with the outer surface of the pusher 94 described later. Further, two bent portions (corner portions) in the inner rib 92R and both ends of the inner rib 92R (both ends near the right lower end and the left lower end in the first piece 92B) are the inner rib 92R. A threaded portion 92C extending in a cylindrical shape in the extending height direction and having a screw hole at the center is integrally formed with the inner rib 92R.

The central piece of the inner rib 92R (horizontal piece constituting the upper end surface in FIG. 41) is slightly closer to the front end side (upper side in FIG. 41) than the front end edge (upper end edge in FIGS. 40 and 41) of the pusher insertion opening 92P. ). In other words, the second piece 92M in the third piece 92T.
The position of the tip edge of the pusher insertion opening 92P is set so that the side wall (left front side wall in FIG. 40) extends to the inside (lower side in FIG. 40) slightly from the center piece of the inner rib 92R.
As a result, a restriction wall portion 92G (see FIG. 40) that restricts the forward movement of the pusher 94, which will be described later, covers the tip portion of the inner rib 92R that is substantially U-shaped in rear view from the second piece 92M side. Is formed.

As shown in FIGS. 42 and 43, the inner body 922 has a three-dimensional outer shape that is similar to the outer body 921 and has a dimension that fits inside the outer body 921.

On both sides of the first spring boss 95L, there are guide walls 95G having a height slightly larger than the length of the leg portion 93L with a gap slightly larger than the width of the leg portion 93L in the movable hook 93 described later. Each of the first pieces 95B extends in parallel to both side surfaces of the first piece 95B from the inner side surface of the front end face wall, and the extending end edge forms a substantially L-shaped planar shape so as to be bent at right angles to both sides. Thus, both the side walls of the first piece 95B and the side wall of the second piece 95M abut against each other and are continuous continuously. The ridge corner portion at the bent portion of the guide wall 95G is formed into a shape that falls into a curved surface. The second piece 95M side wall (the right rear side wall in FIG. 42) of the first piece 95B corresponds to and communicates with a substantially rectangular parallelepiped space formed between the two guide walls 95G. A rectangular end opening 95P for machining is formed. Second piece 95M of first piece 95B
On the inner surface of the side wall, the leg portion 93L is shorter than the length of the leg portion 93L, with an interval slightly smaller than the width of the leg portion 93L in the movable hook 93, directly above the end opening 95P.
Two sliding ribs 95D extending along the length direction are formed. The sliding rib 95D has a semicircular cross section, and both ends are formed in a spherical shape. Further, on the inner surface of the side wall of the second piece 95M of the first piece 95B, an end edge (upper edge in FIG. 42) intersecting with the second piece 95M is slightly smaller than the width of the pusher 94 described later. In this case, two sliding ribs 95E having the same shape and dimensions as the sliding rib 95D are formed.

The inner surface of the side wall (lower side wall in FIG. 42) of the first piece 95B of the second piece 95M is spaced a little smaller than the width of the pusher 94 described later (that is, the above-described two sliding ribs 95E). The sliding ribs 95F each having a semicircular cross section are formed.

A second spring boss 95H having a round bar shape and a hemispherical tip formed at the center of the inner surface of the side wall (the right rear side wall in FIG. 42) opposite to the second piece 95M side of the third piece 95T. Is protruding.

As shown in FIG. 43, corners on both sides of the tip of the side wall opposite to the second piece 95M side in the third piece 95T and both sides of the tip of the side wall of the second piece 95M in the first piece 95B (that is, end opening 95P).
Screw insertion holes 95C each having a conical face counterbore corresponding to a countersunk screw are formed at the corners on both sides of the inner body 922, that is, at the four corners of the entire inner body 922.

As shown in FIGS. 44 and 45, the movable hook 93 has a main body portion 93B having a substantially rectangular dish-like outer shape having a depth in one direction (a direction extending from the lower left to the upper right in FIGS. 44 and 45); From one end surface of the main body portion 93B (the lower end surface in FIGS. 44 and 45), a circumferential wall shape having a substantially U-shaped cross section and a surface in the same direction as the open side surface of the main body portion 93B (the front side surface in FIG. 44) The opened leg portion 93L is a resin molded body having a configuration extending outward (downward in FIG. 44) along the length direction of the main body portion 93B.

As shown in FIG. 44, the inner back wall (right rear side wall in FIG. 44) of the main body portion 93B extends from the substantially central position toward the leg portion 93L while being gently inclined so as to become shallower, and at the tip thereof. Again, it extends to the leg 93L side end of the main body 93B so as to be parallel to a portion (the upper half in FIG. 44) extending from the center of the inner back wall to the side opposite to the leg 93L. As a result, as shown in FIG. 45, the retreat space 93 that is slightly recessed inwardly on the outside of the inner back wall.
R is formed and the outer surface of the inclined portion is a cam surface 93C. In the vicinity of the end (upper end in FIG. 45) of the inner inner wall opposite to the leg 93L side, a rectangular shape extending slightly longer in the width direction of the main body 93B (the direction extending from the upper left to the lower right in FIG. 45). An engagement hole 93P that is (strip-shaped) and penetrates the inner back wall in the thickness direction is formed. Further, the ridge corner formed by intersecting the inner inner wall and the end surface wall (the upper end surface wall in FIG. 45) opposite to the leg portion 93L side of the main body portion 93B is shaped into a curved surface. On the other hand, both the edges of the end face wall (upper end face wall in FIG. 45) and the edge edges formed along the both edges of the inner back wall are also shaped to fall off at right angles to the ridge corner. Yes. The main body 93
On the inner back wall of B, the cam surface 93 in a rectangular area where a retreat space 93R is formed.
The three edges excluding the C-forming side edge (upper edge in FIG. 45) slightly extend so as to form a substantially U-shaped peripheral wall, and the outer surface of the central piece of the leg portion 93L extends from the peripheral wall-shaped portion. It is formed so as to be located on the same plane as the extended end edge. In other words, the engagement hole 93P formation surface in the inner back wall of the main body portion 93B is shaped so as to be slightly retracted inward from the extending end edge of the peripheral wall-shaped portion. As a result, both ends of the peripheral wall-shaped portion are latching portions 93E that protrude from the engagement hole 93P forming surface in the inner back wall of the main body portion 93B.

As shown in FIGS. 46 and 47, the pusher 94 has a rectangular flat plate-like first piece 94B having a slight thickness, from one end edge (upper right end edge in FIG. 46) to one surface side (upper surface side in FIG. 46). A rectangular flat plate-like second piece 94T, which is slightly thicker, extends longer than the first piece 94B, and has a side surface shape that is bent at a right angle in a substantially L-shape as a whole. It has a hollow solid. As shown in FIG. 47, the surface of the pusher 94 opposite to the first piece 94B extending side (the front left side surface in FIG. 47) is opened, and the other seven surfaces are molded so as to be totally closed. . Further, each of the ridge corner portions formed outside in the closed seven-surface portions is formed so as to be dropped.

As shown in FIG. 46, the front end surface of the first piece 94B (the front left side surface in FIG. 46) has a rectangular plate-like engagement piece 94P having a slightly thicker thickness corresponding to the engagement hole 93P in the movable hook 93 described above.
Is protruding. The engagement piece 94P has a corner that falls off at each ridge, and a tip surface of the engagement piece 94P.
It is shaped so as to be a slope whose protruding height gradually increases from the T side (the upper side in FIG. 46) to the opposite side. In addition, sliding ribs 94F are provided at both ends in the width direction of the second piece 94T side surface (upper side surface in FIG. 46) of the first piece 94B along the extending direction of the first piece 94B.
Is formed. The sliding rib 94F has a semicircular cross section, and is shaped so that the semicircular ridge corner at the tip (left end in FIG. 46) falls off. On the other hand, the region (the right rear region in FIG. 46) opposite to the first piece 94B side on the tip surface (the upper end surface in FIG. 46) of the second piece 94T is the first piece 9.
It protrudes slightly from the region on the 4B side and is formed in a step shape, whereby a latching protrusion 94E is formed. The projecting corners at both ends in the width direction of the latching protrusion 94E are shaped to fall into a curved surface.

As shown in FIG. 47, a spring receiving portion 94R extending in a cylindrical shape along the extending direction of the first piece 94B (or the thickness direction of the second piece 94T) is provided at substantially the center inside the second piece 94T. It is integrally formed. Ribs are formed between the spring receiving portion 94R and both side walls of the second piece 94T, respectively, so that the spring receiving portion 94R and the leading edge of the rib are formed in the pusher 94. The first piece 94B is shaped so as to be located on the surface opposite to the extending side (the left front surface in FIG. 47).

As shown in FIG. 39, the movable hook 93 is a first piece in the outer body 921 of the base 92 so that the engagement hole 93P formation side end (the upper end in FIG. 39) is inserted into the hook insertion opening 92H from the inside. It is fitted inside 92B. At this time, the movable hook 93 is disposed so that the engagement hole 93P formation surface (the front left side surface in FIG. 39) faces the third piece 92T side of the outer body 921 of the base body 92. On the other hand, the pusher 94 uses the first piece 94B and the second piece 94T as postures corresponding to the second piece 92M and the third piece 92T in the outer body 921 of the base body 92, respectively, on the inner rib 92R of the outer body 921. Open side, ie pusher insertion opening 92P
From the opposite side to the formation side, the inner body 921 is fitted into the inner rib 92R.

As described above, the inner body 922 is fitted to the outer body 921 of the base body 92 with the movable hook 93 and the pusher 94 housed therein. At this time, the outer body 921 and the inner body 9
The inner body 922 is fitted inside the outer body 921 so that the open side surfaces of the 22 face each other. Further, at this time, as shown in FIG. 38, the first compression coil spring 96 is inserted from one end into the leg portion 93L of the movable hook 93, and the other end is the first of the inner body 922 in the base body 92.
The spring boss 95L is externally fitted and restrained. As a result, as shown by an arrow A18 in FIG. 38, the movable hook 93 is urged in a direction in which the engagement hole 93P formation side end protrudes from the hook insertion opening 92H (upward in FIG. 38). On the other hand, the second compression coil spring 97 is inserted into the spring receiving portion 94R of the pusher 94 from one end, and the other end is the second of the inner body 922 in the base 92.
The spring boss 95H is externally fitted and restrained. As a result, as shown by an arrow A19 in FIG. 38, the pusher 94 moves in the direction in which the first piece 94B side surface (left front side in FIG. 38) protrudes from the pusher insertion opening 92P (lower left in FIG. 38). Is energized. In this state, the outer body 921 and the inner body 922 of the base body 92 are connected to the screw insertion hole 95C of the inner body 922.
It is fixed by screwing a screw into the screwing portion 92C of the outer body 921 and fastening. As a result, all 10 surfaces of the base 92 are closed, and the second hooking device 70 shown in FIG.
B is obtained.

As schematically shown in FIG. 48, the second hooking device 70B has a posture in which the tip of the movable hook 93 is directed to the position where the one side edge (right side edge) of the game board 30 comes. The outer surface (the right rear surface in FIG. 48) opposite to the second piece 95M side of the third piece 95T in 922 is overlapped with the front surface of the inner frame 12, and is the same as in the case of the first hooking device 70A described above. It is fixed at two places above and below. At this time, although the method of fixing the second hooking device 70B to the inner frame 12 is omitted, for example, an appropriate fixing means such as an adhesive may be used, or the first hooking device 70A described above may be used. Similarly to the case, an appropriate screw insertion piece may be formed on the base 92 and fixed with screws. In addition, a space is formed between the first piece 92B of the outer body 921 or the first piece 95B of the inner body 922 and the front surface of the inner frame 12 in the second hooking device 70B in a fixed state (first first). (The pieces 92B and 95B float forward), but the space 92 is filled with a suitable member, or the base 92 of the second hooking device 70B is preliminarily shaped to include this space. That is, as a whole, it is a rectangular parallelepiped shape including this space, and it may be formed so that only the first piece 92T of the outer body 921 and the third piece 95T of the inner body 922 extend. (Omitted). According to this, the second hooking device 70B can be more stably fixed to the front surface of the inner frame 12.

At this time, on the front surface of the inner frame 12, a fixing hook 87 is arranged and fixed at a position corresponding to the center in the height direction on the left edge of the game board 30, as in the first embodiment.

Hereinafter, a procedure for attaching the game board 30 using the second hooking device 70B will be sequentially described.
(A) Before the mounting operation, as shown in FIGS. 49 and 50, the movable hook 93 of the second hooking device 70B is usually housed in the base 92 and set in the open position. If the movable hook 93 is protruded from the hook insertion opening 92H, it is more likely to receive contact from the surroundings and the damage is more likely to occur. It is desirable to store (withdraw).

As indicated by a chain line in FIG. 50, the position where the movable hook 93 protrudes from the hook insertion opening 92H is the closed position. As shown by an arrow A20 in FIG. 50, the movable hook 93 in the closed position is resisted against the urging force of the first compression coil spring 96, that is, the first compression coil spring 96 is compressed. The cam surface 93C of the movable hook 93 resists the urging force of the second compression coil spring 97, that is, compresses the second compression coil spring 97,
The movable hook 93 enters the base 92 while pushing the engaging piece 94P of the pusher 94 backward, that is, toward the inner frame 12 side. When the tip end surface of the movable hook 93 is retracted to a position where the tip end surface of the movable body 92 is just flush with the surface where the hook insertion opening 92H is formed, that is, the open position, the engagement hole 93P of the movable hook 93 reaches the position of the engagement piece 94P of the pusher 94. Then, the engagement piece 94P is fitted and engaged in the engagement hole 93P by the urging force of the second compression coil spring 97. Once the engagement piece 94P is fitted into the engagement hole 93P, the engagement piece 94P is held in this engagement state by the urging force of the second compression coil spring 97. That is, the engagement piece 94P is held in the engagement hole 93P by being urged by the urging force of the second compression coil spring 97, so that the movable hook 93 is entirely accommodated in the base 92. Locked in position.

In the open position, the side surface portion of the first piece 94B in the second piece 94T of the pusher 94 (
50 is the third piece 9 of the base 92 by the biasing force of the second compression coil spring 97.
2T is held at a position slightly protruding forward (downward in FIG. 50) from the surface where the pusher insertion opening 92P is formed. At this time, the base end portion of the second piece 94T of the pusher 94 (the pusher 9
4 is the front edge of the pusher insertion opening 92P (the second piece 92 of the base 92).
The forward movement of the pusher insertion opening 92 </ b> P extending to M is restricted, and the front end of the second piece 94 </ b> T of the pusher 94 is restricted by the latching protrusion 94 </ b> E and the restriction wall of the base 92. By being hooked on the portion 92G, forward movement is restricted.
(B) At the time of attachment work, as shown in FIG. 51, in the same manner as in the first embodiment described above, while the gaming board 30 is tilted so that the right side is further away from the pachinko machine 10,
The left end edge is inserted into the fixed hook 87 from the right front side and is hooked inside the front piece 87F.
(C) Next, in the same manner as in the first embodiment described above, as shown by the arrow A21 in FIG. FIG.
Then, as shown in FIG. 52, the right end is turned to the second hooking device 70.
It is inserted to the position where it abuts against the pusher 94 of B.

At this time, the left side portion of the game board 30 is positioned and held by the fixed hook 87 as in the first embodiment.

On the other hand, in the second hooking device 70B, as in the case of the first hooking device 70A described above, since the movable hook 93 is set at the open position, the right end of the game board 30 is easily fitted. be able to. In particular, the pusher 94 is independent of the movement (displacement) of the movable hook 93.
It is arranged at a certain rear (back) position along the front surface of the inner frame 12, and it moves substantially back and forth with the movement of the movable hook 93, while it is substantially immobile. Since a certain movable hook 93 deviates from the rotation trajectory of the game board 30, the game board 30 can be attached and detached more easily and safely than in the case of the reference hooking device 89 described above. This is the same as the case of the first hooking device 70A described above.
(D) As shown by an arrow A22 in FIG. 52, the right end of the game board 30 is connected to the second hooking device 70B.
As shown in FIGS. 53 and 54, the movable hook 93 of the second hooking device 70B protrudes from the hook insertion opening 92H and returns to the closed position.

At this time, as shown in FIG. 54, when the pusher 94 is pushed backward as the right end of the game board 30 is pushed backward as described above, it is inserted into the engagement hole 93P of the movable hook 93. Then, the engaging piece 94P of the pusher 94 that has been engaged is pulled out rearward from the engaging hole 93P and the engaged state is released, and the movable hook 93 is released from the hook insertion opening 92H by the urging force of the first compression coil spring 96. Extruded in the protruding direction. The movable hook 93 has a hooking portion 9.
When the 3E is hooked from the inner side (not shown) to the peripheral wall of the hook insertion opening 92H in the second piece 92M of the base body 92, the further outward movement is restricted, and the first compression coil spring 96 is attached. The latching position is held by the force.
(E) In the state where the movable hook 93 protrudes from the hook insertion opening 92H as described above and is in the closed position, the force that pushes the right end of the game board 30 backward is removed (released). Due to the urging force of the compression coil spring 97, the pusher 94 pushes the right end of the game board 30 forward and presses it against the movable hook 93 from behind, so that the front of the right end of the game board 30 is on the inner surface of the movable hook 93. Held in position. According to this configuration, as in the case of using the first hooking device 70A described above, the elasticity of the pusher 94 allows the front surface of the game board 30 to be accurately aligned with a predetermined front-rear position while absorbing the thickness variation. Can be attached.

When the game board 30 is removed, the movable hook 93 in the closed position is pushed into the base body 92 to return to the open position. At this time, when the game board 30 is pressed against the movable hook 93 from behind by the pusher 94, it is difficult to move the movable hook 93 due to friction with the game board 30, and the front surface of the game board 30 is easily damaged. When the movable hook 93 is moved while the right end of the game board 30 is pressed backward against the urging force of the second compression coil spring 97, the movable hook 93 is easily damaged without damaging the game board 30. Can be moved.

According to the above attachment process, as in the first embodiment described above, even if the board thickness of the game board 30 varies, the left and right side ends of the game board 30 are fixed to the fixing hook 87 and the second hook respectively. Although the front and rear positions of the front surface can be precisely aligned with a predetermined position by the stopper device 70B, the following advantages are obtained by using the second stopper device 70B.

In the second hooking device 70B, the movable hook 93 in the closed position can be easily pushed into the open position, and the engaging piece 94 of the pusher 94 is opened in the open position.
When P is engaged and engaged with the engagement hole 93P of the movable hook 93 by the urging force of the second compression coil spring 97, the movable hook 93 is easily and reliably locked in the open position. At this time, the second compression coil spring 97 is mainly used to push the game board 30 forward.
4, the engaging piece 94 </ b> P of the pusher 94 is engaged and engaged with the engaging hole 93 </ b> P of the movable hook 93 using this urging force. Perhaps the number of parts is small, and the mechanism is efficiently constructed and simplified.

Further, when the movable hook 93 in the open position is set to the closed position, the pusher 94 is pushed in at the right end of the game board 30 while the game board 30 is moved to the mounting position.
The engagement state of the engagement piece 94P with respect to the engagement hole 93P of the movable hook 93 is released, and the movable hook 93 is pushed out by the urging force of the first compression coil spring 96 to automatically return to the closed position. In other words, by pushing the right end of the game board 30 into the mounting position, the movable hook 93 can be automatically set to the closed position without any other operation, and therefore, the operation is easier. Yes.

Further, since the movable hook 93 and the pusher 94 that are in contact with the game board 30 are made of resin, damage to the game board 30 is reduced, and in addition, the base 72 is also combined with the second latching device. Since the entire 70B is basically made of resin, the second hooking device 70B is light and inexpensive. Furthermore, the movable hook 93 is formed into a shape in which the corner inside the front end that is easy to contact the game board 30 is dropped, and the other ridge corners including the pusher 94 are also formed into a shape in which the corner is dropped. Therefore, the damage to the game board 30 is reduced.
(Operation by Second Embodiment)
The pachinko machine 10 is configured by attaching a game board 30 having a game area on the front side where a game ball flows down to the inner frame 12 of the game machine main body from the front.
Is held in a posture that restricts the front and rear positions of the front surface of the game board 30 from the front when the game board 30 is in the attachment position, and the game board 30 when the game board 30 is in the attachment position. The movable hook 93 of the second hooking device 70B, which is a movable portion that can be displaced from the position of the front surface of the 30 and released to allow the game board 30 to be attached and detached, and the movable hook 93 Regardless of the displacement, the game board 30 is arranged at a certain front and rear position on the rear side of the game board 30, and
And a pusher 94 of the second hooking device 70 </ b> B, which is a pressing portion that presses forward.

According to the above configuration, the game board 30 can be easily moved into and out of the mounting position by displacing the movable hook 93 to the open position, while the game board 30 can be easily moved by displacing the movable hook 93 to the closed position. Can be fixed in the mounting position and therefore the movable hook 9
With the displacement of 3, the game board 30 can be easily attached and detached.

In addition, since the pusher 94 is disposed at a certain front and rear position regardless of the displacement of the movable hook 93, it is difficult to obstruct the game board 30 when it is attached or detached. At this time, if the pressing portion (pusher 91) moves forward as the movable portion (movable hook 90) is displaced to the open position, as in the case of the reference latch device 89, for example, Board 3
There is no expansion of the space for entering and exiting 0, and the pressing portion (pusher 91) is easily attached when the game board 30 is entered and exited, making it difficult for the game board 30 to enter and exit, and the game board 30 to be easily damaged. There is also a problem. On the other hand, according to the configuration of the pachinko machine 10, even if the movable hook 93 is displaced to the open position, the pusher 94 does not move forward and stays at a certain front and rear position. The pusher 94 is difficult to hold when the game board 30 is put in and out, so that the game board 30 can be easily put in and out and the game board 30 is unlikely to be damaged. It is also.

In addition, since the game board 30 arranged at the mounting position is regulated from the front and back by the movable hook 93 displaced to the closed position and is pushed forward by the pusher 94, the front surface of the game board 30 is closed. It is pressed against the movable hook 93 at the position and is held at a predetermined front-rear position. Therefore, even if the board thickness of the game board 30 varies, the front face of the game board 30 is reliably and stably held at a predetermined front and rear position without being affected by this.

The movable hook 93 and the pusher 94 in the open position are each provided with an engaging hole 93P and an engaging piece 94P as an engaging structure, and the engaging hole 93P and the engaging piece 94P
Since the pusher 94 engages with each other by using the pressing force that pushes the game board 30 forward, that is, the urging force of the second compression coil spring 97, the number of parts is small, and the mechanism is configured efficiently. Has been simplified.

Further, the first compression coil spring 9 is moved so that the movable hook 93 moves from the open position to the closed position.
6 and the above-mentioned engagement hole 93P by pushing the pusher 94 backward.
Since the engagement state between the engagement piece 94P and the engagement piece 94P is released and the movable hook 93 is automatically moved to the closed position, the movable hook 93 is automatically moved only by pushing the game board 30 into the attachment position. Therefore, the operation can be simplified and the game board 30 can be easily attached.

Moreover, since the movable hook 93 and the pusher 94 which are parts that come into contact with the game board 30 are made of resin, damage to the game board 30 is reduced.

In addition, the movable hook 93 and the pusher 94 are mounted on the base body 92 so that the second hooking device 70 is mounted.
Since the second hooking device 70B is attached to the inner frame 12, the movable hook 93 and the pusher 94 can be easily arranged on the inner frame 12 at a time. Yes.

Further, since the second hooking device 70B is basically made of resin as a whole (that is, excluding the first and second compression coil springs 96, 97 and screws), it is light and inexpensive. Yes.

(Change mode of latching device)
Various modifications can be made to the pachinko machine 10 according to the first and second embodiments as described below, for example. In the following description and drawings, the same members or parts as those in the first and second embodiments are denoted by the same reference numerals,
The description is basically omitted.
(1) In the first and second embodiments, the first hooking device 70A and the second hooking device 70B are basically made of resin as a whole. For example, it may be made of metal or the like. For example, most of the latching device is made of metal, and a coating layer made of resin, rubber, or the like can be formed on a portion that comes into contact with the game board, such as the inner surface of a movable hook or pusher. It is.
(2) In the first embodiment, the movable hook 72 is moved between the closed position and the open position by pushing and pulling the lock member 84 in the first hooking device 70A. As a configuration, for example, a lever or the like that is operated by rotation may be disposed at a position different from the movable hook, and this can also be configured so that the operation can be easily performed. However, from the viewpoint of preventing the operation space from spreading around as much as possible, it is preferable to adopt a configuration that linearly moves (slides) in the front-rear direction of the gaming machine, like the lock member 84 in the first embodiment. .
(3) In the first embodiment, the first torsion coil spring 83 and the second torsion coil spring 86 are provided as means for biasing the movable hook 72 and the pusher 73 in the first hooking device 70A. For example, as schematically shown in FIG.
2 and the pusher 63 may be urged by the same urging means. The third hooking device 70C shown in the figure has the same configuration as the first hooking device 70A except that a plate spring 64 is provided in place of the first torsion coil spring 83 and the second torsion coil spring 86. It has become. The leaf spring 64 extends long in a band shape and is bent at an intermediate portion so as to have a substantially “h” shape when viewed from the side. As shown in FIG. 55, the rotating portion 62D of the movable hook 62 in the closed position.
Are arranged and fixed at a position between the semicircular tip and the pusher 63. Third hooking device 70
At the position where the intermediate portion of the leaf spring 64 comes on the inner surface of the C base body 65, there are two strips having a substantially “h” -shaped cross section corresponding to the intermediate portion of the leaf spring 64 and protruding inward. The ribs 65R are formed in parallel, and are fixed so that the intermediate portion of the leaf spring 64 is sandwiched between the ribs 65R. One piece 64 </ b> D extending from the middle part of the leaf spring 64 to one side passes through a slit (not shown) formed in the peripheral surface of the distal end portion of the turn part 62 </ b> D in the movable hook 62.
55, and the extended end presses the rotating drum portion 62D from the inside, and the arrow A in FIG.
23, the movable hook 62 is biased toward the open position (counterclockwise in FIG. 55). The other piece 64P extending from the intermediate portion of the leaf spring 64 to the other extends through the slit (not shown) formed in the front surface of the recessed portion of the pusher 63 into the pusher 63, and the extension end of the other piece 64P The pusher 63 is pressed from the inside, and is urged forward (in the clockwise direction in FIG. 55) so that the game board 30 can be pressed from the back side, as indicated by an arrow A24 in FIG.

According to the above configuration, the movable hook 62 and the pusher 63 are urged by the leaf spring 64 which is the same urging means, and can function in the same manner as in the case of the first hooking device 70A described above. . Therefore, the number of parts is reduced and the configuration is simplified.
(4) In the first and second embodiments, the left side edge of the game board 30 is located at one place in the center of the height direction by the fixing hook 87, and the right side edge is located at two places near the upper end and near the lower end. Although fixed by the second hooking devices 70A and 70B, the first and second
The arrangement of the fixing means in the embodiment can be variously changed as listed below, for example.
1. The first and second hooking devices 70A at the right edge of the game board 30 at one central position in the height direction,
Fix with 70B. According to the arrangement, the first and second hooking devices 70A and 70B to be used can be made one, so that the number of parts can be reduced, the configuration is simplified, and the mounting effort is also reduced. Will be. However, in order to correctly introduce the game ball ejected from the launching device to the front surface of the game board 30, the accuracy of the front and rear positions of the lower end portion of the game board 30 is particularly important. Therefore, from the viewpoint of this position accuracy, As in the arrangement in the first and second embodiments, it is desirable that at least the vicinity of the lower end of the game board 30 is fixed by the first and second hooking devices 70A and 70B, and in this case, the game board is used. Since it is difficult to stably support 30 only in the vicinity of the lower end, it is desirable that the vicinity of the upper end be fixed by the first and second hooking devices 70A and 70B.
2. 2. Fix the left side edge of the game board 30 with the first or second hooking devices 70A and 70B at an appropriate position such as one place in the center of the height direction or two places near the upper end and near the lower end. 2. In the arrangement, the right edge of the game board 30 is fixed by the fixing hook 87, that is, the arrangement in the first and second embodiments is reversed left and right. Or 3. According to the arrangement, at least the left side edge of the game board 30 is the first or second side.
It will be fixed by the latching devices 70A and 70B. As described above, the opening / closing axis of the pachinko machine 10 is on the opposite side of the game ball launching handle 18 installation position, that is, on the left side of the pachinko machine 10, and therefore the first and second latching devices 70A and 70B are provided on the game board 30. If the front frame is opened, the operation space is significantly limited by the presence of the front frame as compared to the right side, and the pachinko machine 10 is closed compared to the right side. Since unauthorized tools are difficult to enter, it is desirable from the viewpoint of preventing unauthorized operations. However, on the other hand, since the operation space is narrow, it is disadvantageous for the operation of the first and second hooking devices 70A and 70B in attaching and detaching the game board 30. From this point of view, the first and second Like the arrangement in the second embodiment, the left side edge of the game board 30 may be fixed by a fixing means such as a fixing hook 87 that can be fixed without requiring any operation other than inserting the game board 30. desirable.
4). The first and second embodiments to the above-described 1. ~ 3. In the arrangement of the first to second
Instead of the latching devices 70A and 70B, for example, as in the fourth latching device 70D shown in FIG. 56 and the fifth latching device 70E shown in FIG. 57, at least the base 66 is long along the side edge of the game board 30. 56 is used. The fourth hooking device 70D shown in FIG. 56 has a first face plate 67, a second face plate 68, and a fifth face plate 69 of the base body 66 from the vicinity of the upper end of the side edge of the game board 30. Corresponding to the length to the vicinity of the lower end, it is formed in a shape that extends vertically, and the first face plate 74 of the base 71 is provided at each of the upper and lower ends,
Components of the first hooking device 70A other than the second face plate 75 and the fifth face plate 78, that is, the third face plate 76 and the fourth face plate 77 of the base 71, the movable hook 72, the pusher 73, and the lock member 8 are used.
All of 4 are arranged. In other words, the fourth hooking device 70D has the first
Similar to the embodiment, the first face plate 74, the second face plate 75, and the fifth face plate 78 of the base 71 of the first hooking device 70A arranged in two places near the upper end and near the lower end are respectively in the vertical direction. The first face plate 67, the second face plate 68 and the fifth face plate of the base 66 extend long so as to approach each other.
As the face plate 69, the first hooking devices 70 are arranged in one piece, and thus are arranged vertically.
A is an aspect configured as one fourth hooking device 70D having a base 66 that extends vertically as a whole.

A fifth hooking device 70E shown in FIG. 57 corresponds to the length of the base 66 as well as the movable hook 98 from the vicinity of the upper end to the vicinity of the lower end of the side edge of the game board 30 in the fourth hooking device 70D. The locking member 8 is formed in a shape that extends long in the vertical direction, and is disposed substantially at the center in the height direction.
4 is configured to be operated between an open position and a closed position.

According to the fourth hooking device 70D to the fifth hooking device 70E, the first and second hooking devices 7 are provided at two locations near the upper end and near the lower end as in the arrangements of the first and second embodiments.
Compared to the case where 0A and 70B are respectively disposed, the fourth to fifth hooking devices 70D,
Since 70E itself is large, it is disadvantageous in terms of moldability, handling, storage, etc.
The side edges of the game board 30 can be supported more stably and reliably, and the fourth to fifth hooking devices 70D and 70E can be attached at once rather than vertically, so it is convenient. In addition, since the relative position between the upper and lower sides is fixed in the fourth to fifth hooking devices 70D and 70E, there is no positional deviation between the upper and lower sides, and it is not necessary to position the upper and lower parts. To that extent, positioning can be performed accurately and simply.

Further, according to the fifth hooking device 70E, the movable hook 98 also extends vertically, so that the side edge of the game board 30 can be held more stably, and the movable hook 98 The operation is simple because it can be performed at a time instead of being performed at the top and bottom. The fifth
In the latching device 70E, the movable hook 98 that extends vertically is operated by a lock member 84 disposed substantially in the center in the height direction. For example, in the fourth latching device 70D, The movable hooks 72 disposed on the upper and lower parts may be operated simultaneously by a lock member 84 disposed substantially at the center in the height direction (not shown).
However, in this case, it is necessary to provide a member or mechanism for transmitting power between the lock member 84 and the movable hook 72. Therefore, from the viewpoint of the number of parts and the simplicity of the configuration,
It is desirable to adopt a configuration such as the latching device 70E.

As described above, the fourth hooking device 70D to the fifth hooking device 70E are, as described above, the first face plate 7 of the base 71 in the pair of first hooking devices 70A that are respectively arranged up and down in the first embodiment.
4. The first face plate 67, the second face plate 68, and the fifth face plate 69 of the base 66 are integrally formed by extending the second face plate 75 and the fifth face plate 78 so as to communicate with each other. However, in the same manner as this, a part of the base in the second hooking device 70B respectively disposed above and below may be formed so as to be long in the vertical direction (specific description and illustration). Is omitted).

Furthermore, according to the fourth hooking device 70D to the fifth hooking device 70E, the urging means for urging the movable hooks 72 and 98 and the pusher 73 are respectively arranged up and down (not shown). For example, the urging means is provided only at one location such as the center in the height direction, and the upper and lower movable hooks 72 and the pusher 73 can be moved all at once or vertically by this one urging means. The configuration may be such that the number of biasing means is reduced.

Furthermore, the first and second embodiments to the above-described 1. ~ 3. In the case where the latching devices are arranged at a plurality of locations as in the above arrangement, the same latching device may be arranged at a plurality of locations, but a plurality of different latching devices are arranged at a plurality of locations. You may make it do. For example, on the opening / closing axis line side of the pachinko machine 10, that is, on the left side, a latching device having a configuration with as small a required operation space (movable region) as possible is arranged, and on the right side, the operability is increased even if the operation space becomes large An arrangement in which a latching device having a configuration advantageous in other aspects such as cost is provided.
(5) In the first and second embodiments, the movable hooks 72 and 93, the pusher 73,
94 and the lock member 84 are mounted on the bases 71 and 92 so that the first and second hooking devices 70 are mounted.
A and 70B are configured, but for example, the movable hook (movable portion), the pusher (pressing portion), and the lock member (operating portion) are arranged directly on the gaming machine main body such as the inner frame. However, according to this, the manufacturing process of the latching device and the base as a part can be omitted. However, according to this, since it is necessary to provide a structure for attaching each part to the gaming machine main body such as the inner frame, the configuration of the gaming machine main body such as the inner frame is complicated. If the parts are directly attached to a gaming machine main body such as a large inner frame, the operation tends to become cumbersome. Therefore, as described in the first and second embodiments, the parts are once assembled as a latching device. It is better to attach this latching device to the machine body such as the inner frame.
It is possible to more easily obtain a configuration in which each of the above parts is disposed in the gaming machine main body.

(Third embodiment)
Next, a pachinko machine 150 according to a third embodiment will be described with reference to FIGS. The pachinko machine 10 in the above embodiment can be attached to and detached from the game board 30 by opening the front frame set 14 and operating the latching device, and the model can be changed by replacing the game board 30.

Is provided. This configuration is the same as that in the above embodiment, and a description thereof will be omitted.

  A front frame 151 is supported on the front side of the main body part 153 so as to be openable forward with respect to the main body part 153. As this support structure, an upper and lower support plate 172 formed by processing a metal plate arranged slightly wider than the left end of the front frame 151 is provided on the left side of the main body part 153 when viewed from the front. The upper support plate 172 is provided with a shaft 173 protruding downward, and the lower support plate 172 is provided with a shaft (not shown) protruding upward.

  At the left end of the front frame 151, a groove 174 having a U-shape in a plan view opened rearward is provided at a position corresponding to the shaft 173 of the upper support plate 172 of the main body part 153 (see FIG. 61). The width of the groove 174 is slightly wider than the diameter of the shaft 173, and the shaft 173 of the upper support plate 172 of the main body part 153 enters the groove 174. A shaft 173 is located at the front side end of the pachinko machine 150 of the groove 174, and an end portion of the stopper portion 175 formed by bending a metal wire is formed on the opening direction side (exit side) of the groove 174 with respect to the shaft 173. positioned.

  The stopper portion 175 is urged clockwise in a plan view by a spring built around the rotation shaft 175a and is in contact with a part of the groove 174 at the position shown in FIG. The rear end (the lower end in FIG. 61) of the groove 174 of the stopper portion 175 has a shape that is substantially perpendicular to the outlet side (the upper side in FIG. 61) of the groove 174, and the shaft 173 is the stopper portion. The rotating shaft 175a of the stopper portion 175 is positioned at the tip of the portion that contacts the 175, and the stopper portion 175 prevents the shaft 173 from moving in the direction of withdrawal (upper side in FIG. 61).

  The stopper portion 175 is inclined with respect to the direction of the groove 174 on the outlet side of the groove 174 (upper side in FIG. 61), and when the shaft 173 is pushed into the groove 174 with a certain force or more, the stopper portion 175 The shaft 173 enters the groove 174 by the force in the rotation direction acting and the end of the stopper 175 moving. Therefore, the front frame 151 is attached and fixed to the main body part 153 by aligning the groove 174 of the front frame 151 and the axis of the main body part 153 and pushing the front frame 151 toward the main body part 153 with a force of a certain level or more. The Rukoto.

  The same structure is also provided upside down at the lower left end of the front frame 151, and movement of the shaft in the pull-out direction is prevented by a torsion spring. By manually operating against the urging force of the stopper portion 175, the shaft 173 is allowed to come out and the front frame 151 can be removed.

  The front end of the stopper 175 is exposed to the inside of the pachinko machine 150 (the game board 152 side) when the front frame 151 is opened as shown in FIG. 58, and the front frame is closed when the front frame 151 is closed. 151 is covered with a part. The front frame 151 is locked in a closed state by a locking device (not shown), and cannot be opened unless a store clerk or the like of the game hall performs an unlocking operation. The structure is such that it cannot be operated unless it is operated.

  As shown in FIG. 61, the front frame 151 and the game board 152 are integrated by the left side fixing device 176 and the right side fixing device 177 in the state of the replacement unit 160 alone. The left side fixing device 176 and the right side fixing device 177 can be separated from each other after the front frame 151 and the game board 152 are fixed to the main body part 153, and the front frame 151 is opened to the main body part 153. It is possible.

  The left side fixing device 176 includes an insertion portion 176a that protrudes rearward at two upper and lower positions on the right end of the front frame 151 as viewed from the rear side, and a receiver 176b that is provided at two upper and lower positions on the left end of the game board 152 when viewed from the front. It is comprised by. As shown in FIG. 59 (b), the insertion portion 176 a is arranged at a position that enters the back side of the pachinko machine 150 with respect to the receiving member 176 b of the game board 152, and in the state of the replacement unit 160, The backward movement of the game board 152 is prevented.

  The receptacle 176b is, for example, a part formed by bending a metal plate, and is formed in a shape in which the front right side of the game board 152 is opened in a cross-sectional view as shown in FIG. 59 (b). Yes. The insertion portion 176a located in the receptacle 176b moves to the front right side of the game board 152 when the front frame 151 rotates about the rotation shaft 173 of the front frame 151. By forming the receptacle 176b in a shape that is open on this direction side, in the state of the exchange unit 160, that is, in the state where the front frame 151 is closed with respect to the game board 152, the game board 152 with respect to the front frame 151 When the rearward movement is prevented and the front frame 151 is opened, the insertion portion 176a can be freely removed from the receiving member 176b without performing other operations.

  As shown in FIG. 58, the left side fixing device 176 is arranged on both the upper side and the lower side of the pachinko machine 150 from the maximum horizontal width part that forms the maximum horizontal width L1 of the game area 152a that is partitioned on the front side of the game board 152. The maximum vertical width portion which is arranged and forms the maximum vertical width L2 of the game area 152a is arranged on the left side of the front frame 151 close to the rotating shaft 173 when viewed from the front side of the pachinko machine 150. In particular, since the game area 152a is disposed within the maximum lateral width L1, the game area 152a can be widened within the limited width of the main body part 153 to diversify the game playability. Further, since the left side fixing device 176 is disposed within the maximum vertical width L2 of the game area 152a, the game area 152a is enlarged within the limited height dimension of the main body part 153, thereby diversifying the game characteristics. can do. In addition, the left side fixing device 176 is provided at a position near the rotating shaft 173 of the front frame 151, thereby reducing the influence of the displacement of the insertion portion 176a due to the backlash of the rotating shaft when the front frame 151 is opened and closed. Therefore, the integration of the main body part 153 and the game board 152 by the left side fixing device 176 can be functioned more reliably.

  The right-side fixing device 177 is provided at two upper and lower portions of the right end of the front side of the game board 152 and a cylindrical locking portion 177a protruding rearward at two upper and lower portions of the left end of the front frame 151. And a fixed part 177b. The locking portion 177a is formed of a synthetic resin component that becomes a base of the front frame 151, has a hollow cylindrical shape inside, and has an annular end surface 177a1 with a hole in the center. The game board 152 and the front frame 151 are fixed by the end surface 177a1 coming into contact with the deformed portion 177b1 of the fixed component 177b.

  The fixed component 177b is deformed into a release form and a fixed form by moving the movable part 177b2 back and forth, and a movable part 177b2 supported by the game board 152 so as to be movable between a front release position and a rear fixed position. And a deformable portion 177b1. The deformable portion 177b1 is provided on the front frame 151 side with respect to the movable portion 177b2, the front side (lower side in FIG. 61) is fixed to one end of the movable portion 177b2, and the rear side (upper side in FIG. 61) is the game board. The front surface of 152 can be contacted. The deformable portion 177b1 is formed of a cylindrical deformable part having elasticity by an elastic material such as rubber. The deformable portion 177b1 is elongated in the front-rear direction when the movable portion 177b2 is in the released position, and can be inserted through the hole of the locking portion 177a in this state. When the movable portion 177b2 is moved to the fixed position, the deformable portion 177b1 is compressed and deformed to be inflated in the circumferential direction, and the fixed state is formed because the size cannot be inserted through the hole of the locking portion 177a.

  As shown in FIG. 59 (a), the main body component 153 includes a contact portion 153a that contacts the movable portion 177b2 of the right side fixing device 177 on the back surface side in a state where the game board 152 is attached to the main body component 153. Have. The contact portion 153a is formed at a height that positions the movable portion 177b2 of the right-side fixing device 177 at the front-side release position when the game board 152 is fixed by the latching device 171. When the game board 152 is attached from the front side of the main body part 153 in a state where the movable portion 177b2 of the right side fixing device 177 is disposed at the rear fixed position, the movable portion 177b2 is pressed by the contact portion 153a and is moved from the fixed position. The movable part 177b2 moves to the release position.

  As shown in FIG. 58, the right side fixing device 177 is arranged on both the upper side and the lower side of the pachinko machine 150 from the maximum horizontal width portion that forms the maximum horizontal width L1 of the game area 152a that is partitioned on the front side of the game board 152. When viewed from the front side of the pachinko machine 150, the maximum vertical width portion that forms the maximum vertical width L2 of the game area 152a is arranged on the right side far from the rotation shaft 173 of the front frame 151. In particular, since the game area 152a is disposed within the maximum width L1, the game area can be widened by increasing the width of the game area within the limited width of the main body part 153. Further, since the right side fixing device 177 is arranged within the maximum vertical width L2 of the game area 152a, the game area is enlarged within the limited height dimension of the main body part 153 to diversify the game playability. be able to. In addition, since the right side fixing device 177 is provided at a position away from the rotation shaft 173 of the front frame 151, the amount of movement of the movable portion 177b2 of the fixed component 177b when the front frame 151 is opened and closed is increased. It is possible to more reliably cause the fixed release in conjunction with the movement of the movable portion 177b2.

  In the pachinko machine 150 configured as described above, when changing the model, both the front frame 151 and the game board 152 constituting the replacement unit 160 can be removed from the main body part 153 and a new replacement unit can be attached. As a result, it is possible to renew the design of the front surface of the pachinko machine 150 as compared with the case where only the game board 152 is exchanged by changing the model, and it is possible to easily show the player that the model has been changed.

  Further, the game board 152 is fixedly supported on the main body part 153 by the latching device 171 of the main body part 153, and the front frame 151 is rotatably supported by the support plates 172 provided on the upper and lower sides of the main body part 153. For this reason, when only the game board 152 is to be exchanged, the game board 152 can be easily exchanged with the front frame 151 attached to the main body part 153. Therefore, when the main body parts are shared by a plurality of gaming machine manufacturers and the front frame is different for each manufacturer, only the game board is exchanged for the same manufacturer's model exchange, and the model exchange to a different manufacturer's gaming machine is not This is effective in terms of workability and cost in the case of dealing with exchanging exchange units. In this case, when a payout control board or a power supply board for performing a part of the game control is provided for each gaming machine manufacturer, these boards may be provided on the exchange unit side.

  Here, when a part corresponding to the support plate 172 is provided on the game board 152 and the front frame is supported by the game board so that the front frame can be opened, the game board is fixed when the game board is configured to be replaceable. This can be realized by providing a frame body that supports the front side unit so that it can be opened and closed. However, in this case, the parts cost of the frame body is increased as compared with the conventional pachinko machine. In the pachinko machine 150 according to the present embodiment, the game board 152 and the front frame 151 are separated when the front frame 151 is opened with respect to the game board 152 in a state where the replacement unit 160 is attached to the main body part 153. In addition, parts corresponding to the frame body are not required and the cost of parts can be reduced, and parts can be replaced by the replacement unit 160 and can be replaced as a single game board 152, thereby facilitating the workability of the replacement work. .

  When the replacement unit 160 is attached to the main body part 153, the movable portion 177b2 of the right-side fixing device 177 is pressed by the contact portion 153a, and the movable portion 177b2 moves from the fixed position to the release position. The fixing of the front frame 151 to 152 is released. Further, the left-side fixing device 176 allows the insertion portion 176a to be removed from the receiving member 176b without performing other operations when the front frame 151 is opened. Therefore, the game board 152 and the front frame 151 are separated during the opening operation of the front frame 151 without performing other operations simply by attaching the replacement unit 160 to the main body part 153, so that these separation operations are unnecessary. Therefore, the workability for changing the model can be improved.

  As shown in FIG. 58, the front frame 151 is formed to have a size that completely covers the front side in the vertical direction and the horizontal direction of the pachinko machine 150 with respect to the game board 152. The front frame 151 is fixed to the rear surface side. For this reason, the replacement unit 160 has a conventional crime prevention function, for example, a combination of a groove and a protrusion for eliminating a gap with the main body part 153 on the outer periphery of the front frame 151 by using the game board 152 and the main body part 153 of the conventional size. Even if it is equal, the front frame 151 can be shown in a shape that is enlarged vertically or horizontally from the size of the game board 152 so that the player can easily understand the model change.

  In addition, it is not limited to the description content of each above-mentioned embodiment, For example, you may implement as follows. Incidentally, each of the following configurations may be applied independently to the configuration of each of the above embodiments or a combination of the above configurations, or may be applied to the configuration of each of the above embodiments in a predetermined combination.

  In the above embodiment, the vertical size of the front frame 151 is almost the same as that of the game board 152 and is slightly larger than that of the game board 152, but the operation unit for the launch operation disposed below the front frame 151. In addition, the front frame 151 is extended downward to a part including at least one of an operation unit and a display unit in a case where the ball lending operation or the pachinko ball is circulated in one pachinko machine as a sealed pachinko machine. In this case, there is an effect that fraud targeting the mating surface between the front frame 151 and the lower portion thereof can be prevented. In addition, when the configuration of the replacement unit 160 described above is adopted as an encapsulated pachinko machine, it is preferable to provide a ball polishing device, a ball circulation device, an out-ball counting device, etc. on the main body part 153 side. It is preferable that the display unit for the number of balls required for the pachinko machine of the type, the balance display unit of the player corresponding to cards and cash, or the operation unit for them is also provided on the main body part side. May be provided with a transparent member that covers those display units, or may be provided with a window unit that exposes the display unit and the operation unit on the front side of the pachinko machine 150.

  The structure for fixing the front frame so as to be rotatable is not limited to the above-described form, but other forms may be adopted, but a configuration in which the front frame 151 can be attached to the main body part 153 by a pushing operation is preferable. For example, the U-shaped groove 174 and the stopper 175 described above are used only on the upper side, and the lower side is simply a combination of a shaft and a hole, and the lower side of the front frame is aligned with the main body part. The front frame may be fixed to the main body part by pushing the upper side later, or the left end of the front frame is aligned with the left end of the main part as a combination of a shaft hole and a shaft in both the upper and lower sides. After that, the front frame may be fixed to the main body part by pushing the right side.

  The left-side fixing device 176 and the right-side fixing device 177 do not necessarily need to be arranged in the number and combination described above. For example, the left side of the game board 152 is fixed in the same manner as the right-side fixing device 177 because the game board 152 is fixed. You may employ | adopt the structure separated. Here, in the case of adopting a device that restricts only the forward / backward movement without restricting the rotational movement like the left side fixing device 176, the front frame 151 and the game board 152 are rotated only by the device having the structure. Since it cannot be integrated impossible, a part for preventing relative rotation between the front frame 151 and the game board 152 similar to the right side fixing device 177 described above is provided, or is integrated as a part different from the replacement unit 160. A stopper may be provided on the side far from the rotation shaft, and the stopper may be removed before or after the replacement unit 160 is attached to the main body part 153.

  The left-side fixing device 176 and the right-side fixing device 177 are not necessarily configured to be fixed and released only by attaching the replacement unit 160 to the main body part 153. Fixing is released by an operation (for example, an operation of releasing a fixing device (for example, a fixing lever) different from the left side fixing device 176 and the right side fixing device 177, or an operation of removing a fastener such as a screw). It is good also as a structure.

  The right-side fixing device 177 does not necessarily change between the fixed state and the separable state due to the deformation of the deformation portion 177b1, and is fixed by the stopper member that moves in the left and right or up and down directions of the pachinko machine by the movement of the movable portion. The separable state may be changed. Also, it is not necessary to have a configuration in which the fixed state is released by the operation of the mechanical member by the pushing operation, and it is operated by a switch as a detecting means for detecting that the pushing operation has been performed and an electric signal from a solenoid, a motor, or the like. It is also possible to provide a driving means for changing the fixed state and the separable state. In this case, the separable state may be set while the power is on, and the fixed state may be set when the power is off.

  The left side fixing device 176 and the right side fixing device 177 are not necessarily arranged within the width of the maximum horizontal width L1 of the game area 152a or the width of the maximum vertical width L2 of the game area 152a. There is also an effect, and a configuration in which the width is arranged outside both widths may be adopted. In addition, it is not always necessary to arrange the fixing devices at the upper and lower positions, and one or three or more fixing devices may be provided.

  The hooking device 171 may be only on the right side instead of the left and right sides. The numbers do not have to be one above the other. Not only the same structure but also different structures may be combined. In addition to the fixing structure by pushing operation, other fixing structures such as opening the front frame 151 and rotating and fixing the locking lever may be combined.

  Other types of pachinko machines different from the above-described embodiments, such as pachinko machines that release a predetermined number of times when a game ball enters a specific area of a special device, or a game ball enters a specific area of a special device The present invention can also be applied to a pachinko machine that generates a big hit when a right is generated, a pachinko machine equipped with other objects, an arrangement ball machine, a sparrow ball, and the like. Moreover, it may be implemented as various gaming machines such as a gaming machine in which a so-called pachinko machine and a slot machine are integrated, or may be implemented as a slot machine.

  In a gaming machine in which a slot machine or a pachinko machine and a slot machine are combined, a replacement unit including a part provided with a reel or the like instead of the gaming board 152 and a door-like member covering the front side of the part Similarly to the game board 152 and the front frame 151 constituting the 160, the exchange unit may be integrated by a fixing device.

<Invention Group Extracted from Each Embodiment>
Hereinafter, the characteristics of the invention group extracted from each of the above-described embodiments will be described while showing effects and the like as necessary.
[Background art of the invention relating to means A1 to means A9 / Problems to be solved by the invention]
A gaming machine such as a pachinko machine is provided with a game board in which a game area where a game ball flows down is formed on the front surface, and a game ball can be guided to the game area of the game board to play a game. Is common. In conventional gaming machines, a structure in which a gaming board is attached from the back side of the gaming machine has been mainstream, but there is a problem that efficiency is poor because it takes time to attach and detach the gaming board. Therefore, for example, as disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 6-47157), it has been proposed to have a structure in which a game board is attached from the front side of the game machine. In the structure described in Patent Document 1, a gaming board is arranged from the front side of the gaming machine, and a hook member is locked from the side to the side edge of the gaming board, so that the gaming board is brought into the mounting position. It is intended to be fixed. According to this, for example, it is possible to perform a game board replacement operation or the like from the front side while the gaming machine is installed in the game hall, so that the gaming board can be installed in a state where the gaming machine as the attachment destination is stable. When the work can be performed from the back side because it is only necessary to open the front frame when replacing the game board from the front side of the gaming machine, etc. There is also an advantage that it takes less time to open the gaming machine.

By the way, particularly in the case of a pachinko machine, it is important to accurately align the relative front and back positions of the front surface of the game board with respect to the launch device arranged below the game board. This causes a problem that the game ball launched from the device is not correctly introduced into the game area of the game board. Conventionally, since the gaming board is attached from the back side of the gaming machine as described above, the gaming board is positioned in contact with the gaming machine main body on the front surface, and therefore the front and rear positions of the front surface of the gaming board are the gaming machine main body. However, the above-described positional deviation is hardly generated. On the other hand, in the case where the gaming board is attached from the front side of the gaming machine, the gaming board is positioned in contact with the gaming machine main body on the back side, and therefore, for example, the board thickness of the gaming board varies. In some cases, there is a problem that the front and rear positions of the game board also vary and the above-described positional deviation occurs.

However, according to the description of Patent Document 1, the locking position by the hook member is set so as to come to a certain position with a predetermined distance from the frame of the gaming machine body forward by a predetermined thickness. However, it does not take into account the problem of misalignment caused by the variation in the board thickness of the game board as described above. For this reason, for example, if the gaming board becomes thinner than a predetermined thickness due to variations in the board thickness of the gaming board, the gaming board will rattle back and forth, while if the gaming board becomes thicker than the predetermined thickness, it will be locked by the hook member. In any case, it is difficult to accurately and stably match the front and rear positions of the front surface of the game board. Therefore, the structure described in Patent Document 1 must be said to be insufficient in terms of positioning and stability of the game board. In other words, the structure described in Patent Document 1 described above is easy to attach and detach the game board by attaching the game board from the front side of the gaming machine, but with this structural change. Although a new problem of variation in the position of the front surface of the game board has arisen, it can be said that this problem has not yet been considered.
