The display unit 173 is moved forward and backward by the front surface of the display frame unit main body 172 and the front clear cover 179. Even in a substantially pinched state, it can move smoothly up and down and left and right within the internal storage space 183.

  The display panel fixing part 176b of the front sliding member 176 is arranged so as to protrude into the display panel storage part 189 at a position on the rear side by the thickness of the liquid crystal display panel 175 from the front end face of the side wall of the display unit case 174. Has been. The display panel fixing part 176b is formed with a screwing part (boss) 176c for fixing the liquid crystal display panel 175 in the display panel storage part 189 with screws.

  The display unit case 174 includes a liquid crystal display panel 175 stored in the display panel storage unit 189 on the front side of the display unit case 174, and an effect control device 33 disposed on the back side of the back mechanism frame 160. A wiring opening 191 penetrating in the front-rear direction for passing a wiring for connecting the two is formed. The wiring opening 191 is formed corresponding to the position of the connector 175a provided on the back side of the liquid crystal display panel 175, as will be described later. The liquid crystal display panel 175 is connected to the display panel storage portion 189 of the display unit case 174. The connector 175a is exposed from the wiring opening 191.

  As shown in FIGS. 8 and 9, the liquid crystal display panel 175 has a rectangular plate shape and is sized to fit in the display panel storage portion 189 of the display unit case 174. The liquid crystal display panel 175 includes a liquid crystal display 55 and a backlight 56, and is arranged so that the image display surface 171 of the liquid crystal display 55 faces the front side. Therefore, the image display surface 171 of the liquid crystal display panel 175 is disposed so as to be visible from the front side of the display frame unit 170 through the front clear cover 179.

  Further, on the front side of the liquid crystal display panel 175 and on the left and right sides of the image display surface 171, screw holes 193, 193,. These screw holes 193, 193,... Are formed so as to penetrate in the front-rear direction. With the liquid crystal display panel 175 stored in the display panel storage portion 189, screws are inserted into the screw holes 193, 193,. The liquid crystal display panel 175 can be fixed to the display panel storage portion 189 by being screwed into the screwing portion 176c of the front sliding member 176 provided in the display unit case 174.

  The area of the image display surface 171 of the liquid crystal display 55 is an area where the upper half of the game board 1 fitted in the opening formed in the front frame body 130 can be covered from the back side. 11 is wider than the display window portion 12 formed by 11. In other words, the area of the image display surface 171 is at least larger than that of the display window portion 12, so that even if the size of the display window portion 12 changes, it can cope with it. As described above, the image display surface 171 of the liquid crystal display 55 covers the back side of the game board 1 widely, so that various game contents of the gaming machine 100 can be changed by replacing the game board 1. It can be adapted to the display window 12 of the game board 1.

  The liquid crystal display 55 is controlled by the effect control device 33 so that an image is displayed in an area exposed from the display window 12 because the area of the image display surface 171 is larger than that of the display window 12. Yes. Information regarding the size and position of the display window 12 of the game board 1 that determines the area for displaying the image is stored in the game control device 30, but the game control device 30 is attached to the game board 1. The game control device 30 is also exchanged together with the game board 1. Therefore, with the replacement of the game board 1, for example, the image display area corresponding to the display window part of the game board so far can be changed to the image display area corresponding to the display window part 12 of the new game board 1. It is like that.

  With the configuration described above, the display unit 173 including the liquid crystal display 55 is held by the display frame unit 170 so as to be movable in the vertical and horizontal directions, and the display frame unit 170 is held by the back mechanism frame 160 so as to be movable back and forth. Will be. That is, the display unit 173 is held by the back mechanism frame 160 so as to be movable in the front-rear, up-down, and left-right directions.

Next, position adjustment of the display unit 173 will be described. The position adjustment of the display unit 173 is performed, for example, when the game board 1 is attached to the front frame 120 from the front side with the back mechanism frame 160 closed, or the game board 1 is attached to the front frame body 130 for maintenance or the like. This is performed when the back mechanism frame 160 is changed from being opened to being closed.
Here, as an example, the position adjustment of the display unit 173 when the back mechanism frame 160 is changed from the opened state to the closed state will be described with reference to FIG.

  Note that the front frame 120 shown in FIG. 12 is configured such that the game board 1 is detachably fitted and fixed to the opening 131 formed in the front frame main body 130 from the back side. The opening 131 is provided with a regulating wall 133, a rear pressing member 134, a positioning member 136, and a game board fixing member (not shown) as members for fixing the game board 1 at a predetermined position in the opening 131. Yes.

As shown in FIG. 12A, the regulation wall 133 is a plate-like member extending in the center direction of the opening 131 perpendicular to the inner surface of the opening 131, and the opening of the front frame body 130. 131 is provided in front of the rear end portion around 131 by the thickness of the game board 1. That is, the regulation wall 133 is in contact with the front surface of the game board 1 and regulates the movement of the game board 1 in the forward direction.
In addition, in the front surface of the surrounding component member 17 provided on the front surface of the game board 1, a concave portion 17 a is formed in a portion where the restriction wall 133 abuts, and the game board 1 is accommodated in the opening 131. Part of the regulating wall 133 is accommodated in the recess 17a, and the front surface of the regulating wall 133 and the front surface of the surrounding component member 17 are substantially flush with each other. In this state where the game board 1 is accommodated in the opening 131, the back surface of the game board 1 (the back surface of the game board body 10) is substantially the same as the rear end portion around the opening 131 of the front frame body 130. The front and rear positions of the restriction wall 133 are set so as to be arranged at the front and rear positions.

Positioning members 136 that determine the left and right positions of the game board 1 are provided on the back surfaces of the restriction walls 133 on the left and right sides of the opening 131.
Two positioning members 136 are provided on each of the left and right regulating walls, one pair on the upper side and one on the lower side of the opening 131 in the vertical direction, and a pair of positioning members facing each other with the opening portion interposed therebetween. 136 and 136 are arranged in the same vertical position.

  Of the positioning members 136 provided on the left and right sides of the opening 131, the positioning member 136 on the side on which the back mechanism frame 160 is pivotally attached is a rectangular plate-like member, and is regulated so that its plate surface is horizontal. It is provided in contact with the back surface of the wall 133, the inner surface of the opening 131, and the front surface of the rear pressing member 134 described later. Note that the protruding width of the positioning member 136 in the center direction of the opening 131 is smaller than the protruding width of the regulating wall 133.

The positioning member 136 provided on the side of the opening 131 opposite to the side on which the back mechanism frame 160 is pivotally attached is a plate-like member having a shape in which one corner of a rectangle is cut off.
The positioning member 136 is in contact with the rear surface of the regulating wall 133 and the inner surface of the opening 131 so that the plate surface thereof is horizontal, and the portion where the corner portion is cut off and becomes the oblique side is the inner side and the rear side of the opening 131. It is provided so as to be arranged on the side where the game board 1 is inserted.

  Further, the distance between the side end portions of the positioning member 136 facing each other across the opening portion of the opening portion 131 and located inside the opening portion 131 is substantially the same as the lateral width of the game board 1. It has become. As will be described later, the positioning member 136 can guide the game board 1 to a predetermined position of the opening 131 when the game board 1 is attached, and the game is completely accommodated in the opening 131. Abutting on the side surface of the board 1 can restrict the movement of the game board 1 in the left-right direction.

In addition, a rear pressing member 134 that contacts the rear end portion of the game board 1 is provided at the rear end portion around the opening 131 of the front frame main body 130 on the side on which the back mechanism frame 160 is attached. Yes.
The rear pressing member 134 is a plate-like member, and is provided so as to protrude in the center direction of the opening 131 perpendicular to the inner surface of the opening 131 like the restriction wall 133. The plate surfaces of the regulating wall 133 and the rear pressing member 134 are parallel to each other, and the protruding width from the inner surface of the opening 131 is the same width. Further, the front surface of the plate-shaped rear pressing member 134 and the end portion on the center side of the opening 131 is an inclined surface that is inclined backward toward the tip.

  From the above, the inner wall of the opening 131 on the side on which the back mechanism frame 160 is pivotally attached is defined by the restriction wall 133, the rear pressing member 134, and a part of the inner surface of the opening 131, as will be described later. When the game board 1 is attached to the opening 131, an insertion recess 135 into which one end of the game board 1 is inserted is formed. And in this insertion recessed part 135, the positioning member 136 for determining the left-right position of the game board 1 mentioned above is provided.

  Further, a game board fixing member (not shown) is provided at a predetermined position on the back surface of the regulation wall 133 so that the game board 1 is fixed in the opening 131. That is, the game board fixing member has a fixing part that can be converted into a state in which the game board 1 is in contact with the back surface of the game board 1 accommodated in the opening 131 and a state in which it is retracted from the back surface of the game board 1. The board can be fixed and released.

  When the game board 1 is attached to the front frame 120 configured as described above (here, it is assumed that the old game board has already been removed and the back mechanism frame 160 is open). The left side edge of the game board 1 as viewed from the front side is inserted into the insertion recess 135 obliquely from the rear side of the opening 131 with the surface on which the game area is formed as the front side. Note that the front-side end of the rear pressing member 134 that forms the insertion recess 135 is an inclined surface, so that the game board 1 can be easily inserted into the insertion recess 135.

  Next, the gaming board 1 is fitted into the opening 131 while rotating the gaming board 1 to the front side of the gaming machine 100 with the portion inserted into the insertion recess 135 as an axis. At this time, the side end of the game board 1 opposite to the side inserted into the insertion recess 135 abuts on the oblique side of the positioning member 136 and is guided along the oblique side toward the inside of the opening 131. Further, when the side end is guided to the end inside the opening 131 of the hypotenuse along the hypotenuse, the side end is guided to the front side of the gaming machine 100 along the side surface of the positioning member 136 continuing to the hypotenuse. Then, when the front surface of the game board 1 is in contact with the back surface of the restriction wall 133, the forward movement is restricted, and the side surface of the game board 1 continuing to this side end is at the side end of the positioning member 136. Abut. Further, the side end portion of the game board 1 on the side inserted into the insertion recess 135 also comes into contact with the side end portion of the positioning member 136, so that the game board 1 is completely accommodated in the opening 131. .

When the game board 1 is completely fitted into the opening 131, the game board 1 is fixed in the opening 131 by rotating the fixing part of the game board fixing member so as to contact the back surface of the game board 1.
In a state where the game board 1 is completely fitted in the opening 131, the regulation wall 133 comes into contact with the front surface of the game board 1, and the fixed portion of the game board fixing member comes into contact with the back surface of the game board 1. 1 is restricted from moving in the front-rear direction. Further, the side end portions of the positioning members 136 and 136 are in contact with the side end portions of the game board 1 so that the movement of the game board 1 in the left-right direction is restricted.
It should be noted that the dimension between the side end portions of the left and right positioning members 136, 136 is preferably slightly larger than the dimension in the left-right direction of the game board 1, but in this case, the game board fixing member is attached to the game The board 1 can be fixed so as not to move to the left and right (for example, a structure in which the game board 1 is pressed to the left and brought into contact with the side end of the positioning member 136 to restrict the movement in the left-right direction. And).

Then, with the game board 1 attached to the front frame 120 in this way, the back mechanism frame 160 is rotated from the opened state to the closed state.
First, in a state in which the back mechanism frame 160 is opened, the display frame unit 170 held by the back mechanism frame 160 is movable back and forth within the display frame unit storage portion 168 and is a compression coil as an urging member. It is housed in a state where it is urged forward by the spring 182, and when the back mechanism frame 160 is opened, the front surface of the guided portion 18 is disposed at a position in contact with the front position regulating member 180.

  The front surface of the front clear cover 179 that forms the front surface of the display frame unit 170 provided in the back mechanism frame 160 is behind the game board 1 in the process of rotating the back mechanism frame 160 as shown in FIG. It abuts on the rear end portion 16 of the center case 11 projecting toward the center. However, since the game board 1 is restricted from moving forward by the restriction wall 133, the display frame unit 170 is pressed to the rear side of the gaming machine 100. The display frame unit 170 can move back and forth with respect to the back mechanism frame 160 and is urged forward by a compression coil spring 182 as an urging member. Therefore, when the front surface of the display frame unit 170 abuts against the rear end portion 16 of the center case 11 and is pressed backward, the display frame unit 170 is reared against the urging force of the compression coil spring 182 as the urging member. Will be pushed in the direction. Further, the guide guide portions 137a and 138a of the position adjusting members 137 and 138 protruding rearward of the game board 1 are placed on the rollers 20b and 21b of the position adjusted portions 20 and 21 provided on the side of the display unit 173. Come into contact.

  Here, the back mechanism frame 160 rotates around the rotation shafts 139 and 139 formed on the back surface of the front frame body 130, so that the rotation shaft 139 The rear end portion on the side close to 139 contacts the front surface of the display frame unit 170 first. The display frame unit 170 can be tilted in the display frame unit storage portion 168 (the display frame unit 170 is not parallel to the left-right direction of the front frame 120 (front frame main body 130)). 11 in which the rear end portion 16 abuts is moved in an inclined state so as to be pushed further backward.

  The back mechanism frame 160 gradually follows the left and right direction of the gaming machine 100 by rotating, and the back mechanism frame 160 is completely arranged on the back side of the game board 1 as shown in FIG. In the installed state (the state in which the back mechanism frame 160 is closed), the game board 1 is parallel to the left-right direction. Further, the inclination of the display frame unit 170 gradually follows the left-right direction of the gaming machine 100 by rotating the back mechanism frame 160. Thus, in a state where the back mechanism frame 160 is completely disposed on the back side of the game board 1, the front surface of the display frame unit 170 is in surface contact with the rear end portion 16 of the center case 11, and the left and right sides of the game board 1 are It becomes a state parallel to the direction. Then, the back mechanism frame 160 is fixed to the front frame body 130 by a back mechanism frame closing member (not shown) on the side of the back mechanism frame 160 that is not pivotally attached to the front frame body 130. It is fixed in a state of being arranged on the back side of the game board 1.

  Note that at the beginning of the process of rotating the back mechanism frame 160, the back mechanism frame 160 has a large inclination with respect to the rear end portion 16 of the center case 11 parallel to the left-right direction of the gaming machine 100, and the display frame unit 170 can be inclined. Since it is larger than the range, a part of the rear end portion 16 of the center case 11 is in contact with the front surface of the display frame unit 170. However, if the tilt of the back mechanism frame 160 with respect to the rear end portion 16 of the center case 11 falls within the tiltable range of the display frame unit 170 as the back mechanism frame 160 rotates, the front of the display frame unit 170 is thereafter handled. Is in surface contact with the rear end portion 16 of the center case 11.

  Further, since the display frame unit 170 is urged forward by the urging member (compression coil spring 182), the front surface is held in a state of being in close contact with the rear end portion 16 of the center case 11. The image display surface 171 can be viewed from the front surface of the game board 1 through the display window portion 12 formed by the center case 11.

As described above, the display frame unit 170 is pushed backward, and at the same time, the vertical and horizontal positions of the display unit 173 are adjusted to a predetermined position.
In the process of closing the back mechanism frame 160, the rollers 20b and 21b of the position-adjusted portions 20 and 21 in contact with the position adjusting members 137 and 138 are inclined inside the guide guide portions 137a and 138a, which are V-shaped grooves. It is guided to the engagement fixing portions 137b and 138b at the center of the groove along the surface.
In other words, the roller 20b of the position adjusting unit 20 disposed substantially horizontally on the display frame unit 170 (the roller 21b of the position adjusting unit 21 disposed substantially vertically to the left of the display frame unit 170) is adjusted in position. The member 137 (138) is guided in the vertical direction (left-right direction) by the guide guide portion 137a (138a) having a V-shaped cross section, and is formed in a cylindrical shape in the engagement fixing portion 137b (138b) which is a semicircular groove in cross section. The roller 20b (21b) comes into engagement.

  As described above, the position adjustment unit 20 (21) having the roller 20b (21b) is provided in the display unit 173 that is held so as to be movable in the vertical and horizontal directions in the internal storage space 183 of the display frame unit 170. Thus, the roller 20b (21b) is guided and engaged with the engagement fixing portion 137b (138b), whereby the vertical (left / right) position of the display unit 173 is determined.

  Here, the display unit 173 can be moved up and down and left and right smoothly in the internal storage space 183 by the front sliding member 176 and the back sliding means 184, and the rollers 20b and 21b are supported by bearings 20d, 20d, 21d and 21d. The display frame unit 170 is urged forward by a compression coil spring 182 as an urging member. Therefore, in the process of closing the back mechanism frame 160, the rollers 20b, 21b of the position adjustment parts 20, 21 are easily and reliably guided to the engagement fixing parts 137b, 138b of the position adjustment members 137, 138. The vertical and horizontal positions of the display unit 173 are reliably adjusted to a predetermined position.

  Further, since the display frame unit 170 is urged forward, the engagement formed at the center of the V-shaped groove (the bottom portion of the V-shaped groove) as the guide guide portions 137a and 138a. The rollers 20b and 21b engaged with the mating / fixing portions 137b and 138b are in a state of being substantially fixed by restricting movement in the vertical (left and right) direction and movement in the forward direction. This substantially fixed position is the position of the display frame unit 170 in use after setting.

  As described above, when the position adjustment members 20 and 21 are engaged with the position adjustment members 137 and 138 and the front, rear, left, right, top and bottom positions of the display unit 173 are accurately determined, the display window 12 of the center case 11 The position of the image display surface 171 (image display area) of the display unit 173 to be exposed is accurately determined. As a result, the position of the image displayed on the image display surface 171 and the position of the display window portion 12 is not shifted, and an image with no positional deviation can be viewed from the display window portion 12.

  It should be noted that the engagement fixing portions 137b and 138b of the position adjusting members 137 and 138 are at substantially the same front and rear positions as the rear end portion 16 of the center case 11, and the front end portions of the rollers 20b and 21b of the position adjusting portions 20 and 21. And the front surface of the front clear cover 179 (the front surface of the display frame unit 170) are substantially in the same front-rear position. Therefore, when the back mechanism frame 160 is closed, the front surface of the front clear cover 179 is placed on the rear end portion 16 of the center case 11. Are brought into surface contact with each other, and the rollers 20b and 21b are engaged with the engagement fixing portions 137b and 138b.

If the back mechanism frame 160 is in a closed state, the end (open end) of the back mechanism frame 160 on the side not pivotally attached to the front frame body 130 is fixed to the front frame body 130 by a back mechanism frame closing member (not shown). To do.
Further, the box 33a in which the effect control device 33 is housed is rotated rearward before the back mechanism frame 160 is closed, and the effect control device arrangement portion is set after the back mechanism frame 160 is closed. It is rotated forward so that it is accommodated in 165. By rotating the box 33a containing the effect control device 33 forward, the connector 33m of the effect control device 33 and the connector 32f of the effect data device 32 are connected and both are directly connected.

  From the above, the back mechanism frame 160 has a slide portion (guide portion 169) that can move the display unit 173 back and forth, and biasing means (compression coil spring) that biases the display unit 173 forward. 182) and the rear mechanism frame 160 is closed, the rear end 16 of the game board 1 abuts against the front surface of the display unit 173 so that the display unit 173 resists the urging force of the urging means. It will move to the rear side.

  In addition, the game board 1 is mounted from the rear side of the front frame 120.

In the above description, the game board 1 is attached to the front frame 120 from the back side. However, the game board 1 may be slid from the side.
Moreover, it is good also as a structure which attaches the game board 1 from the front side of the front frame 120 like the front frame 120 shown in FIG. In this case, the game board 1 is mounted on the front frame 120 with the back mechanism frame 160 closed, and the position of the display unit 173 is adjusted at this time. As described above, when the game board 1 is mounted on the front frame 120 with the back mechanism frame 160 closed, the position adjusting members 137 and 138 provided on the game board 1 operate so as to move backward. However, the game board 1 and the back mechanism frame 160 relatively operate in the same manner as described above, and the position of the display unit 173 is adjusted in the same manner as described above. Even if the game board 1 is mounted from the front side, the back mechanism frame 160 may be opened for maintenance or the like. In this case, when the back mechanism frame 160 is closed again, the display unit 173 Position adjustment will be performed.

  That is, when the back side of the game board 1 attached to the front frame 120 is changed from an open state to a closed state, or when the game board 1 is attached to the front frame 120, the back side of the game board 1 is attached to the back mechanism frame 160. The position of the display unit 173 is adjusted when the display unit 173 is positioned behind the game board 1 as in the case where the display unit 173 faces the front surface of the display unit 173. Then, the image display surface 171 of the display unit 173 is arranged at an appropriate position with respect to the display window portion 12.

  In the gaming machine 100 of the present embodiment, the display unit 173 is configured to be movable in the left-right direction and the up-down direction, but may be configured to be movable in only one direction, the left-right direction or the up-down direction. That is, the position adjustment member 138 (137) is provided only on the left side (upper side) of the center case 11 on the back surface of the game board 1, and the display unit 173 is provided with the position adjustment unit 21 (20) only on the left side (upper side). The display unit 173 may be configured to be movable only in the left and right (up and down) directions. Further, when the display unit 173 is configured to be movable only in the left and right (up and down) directions as described above, for example, the movement of the display unit 173 in the vertical (left and right) direction within the internal storage space 183 is restricted. By providing a guide or making the vertical (left / right) width of the internal storage space 183 substantially the same as the vertical (left / right) width of the display unit 173, the display unit 173 is reliably moved only in the left / right (vertical) direction. You may do it.

From the above, the display unit 173 is disposed on the back mechanism frame 160 so as to be movable in the left-right direction and / or the up-down direction, and the position adjustment member that can adjust the position of the display unit 173 on the back surface of the game board 1. 137 and 138 are provided, and when the position adjusting portions 20 and 21 corresponding to the position adjusting members 137 and 138 are provided in the display unit 173 and the back mechanism frame 160 is closed, the position adjusting members 137 and 138 are covered. By acting on the position adjusting units 20 and 21, the display unit 173 is moved to an appropriate position with respect to the display window 12 formed on the game board 1.
Here, the position adjusting members 137 and 138 may be a single mechanism member attached directly to the game board 1 as described above, or, as will be described later, other members (for example, You may make it provide in the back surface structural member 40).

Next, holding of the back mechanism frame 160 in the open state by the fixing means 230 will be described.
This fixing means 230 keeps the open state of the back mechanism frame 160, thereby facilitating the work at the time of exchanging the game board 1 or the maintenance as described above.

  First, as shown in FIG. 1, from the state in which the front frame 120 is closed with respect to the machine frame 110, the front frame 120 is rotated into a door shape to be in a state opened with respect to the machine frame 110. The front frame 120 is locked to the machine frame 110 by a locking device, and is released after unlocking. Further, the back mechanism frame 160 is provided on the open end side of the back mechanism frame 160, and is fixed by the back mechanism frame closing member (not shown) for fixing the back mechanism frame 160 to the front frame 120. Open to it. Then, as shown in FIG. 2, the front frame 120 is opened with respect to the machine frame 110, and the back mechanism frame 160 is opened with respect to the front frame 120. In this state, the fixing member 231 provided on the side surface of the back mechanism frame 160 is operated, and the engagement groove 232 is engaged with the engaged portion 112 of the engaged member 111 provided in the machine frame 110.
