Description

  The present invention relates to a gaming machine such as a pachinko machine, an arrange ball machine, and a slot machine.

  In recent years, pachinko machines and other gaming machines equipped with large liquid crystal display means have become mainstream, and each company is trying to differentiate it from other companies' products by the production images displayed on the liquid crystal display means. .

  However, it is not enough to differentiate only by virtual effect images displayed on the liquid crystal display means, and it is difficult to fully differentiate from other companies' products. In order to enhance the production effect, for example, a liquid crystal display means having a double door type door on the front side has been developed (see Patent Document 1).

  The slot machine described in Patent Document 1 is provided with a pair of left and right drive doors that can move in the left-right direction on the front side of the liquid crystal display means. Opening and closing drive is performed between a fully closed position contacting the front side of the display means and a fully open position retracting on both the left and right sides of the liquid crystal display means.

  Each drive door is provided with a rack along its upper edge side or lower edge side, and a pinion gear fixed to the drive shaft of the motor meshes with this rack.

In order to enable the drive door to move between the fully open position and the fully closed position, the rack needs to be formed longer than the full width of each drive door. The racks of the drive doors are arranged so as to protrude outward from the open side edge so that the racks do not interfere with each other when the drive doors are opened and closed.
JP-A-2005-540

  As in the slot machine described in Patent Document 1, in the case where the rack of each drive door is arranged to protrude outward from the open side edge, when the drive door reaches the fully open position, the protruding portion of the rack is Since the entire drive door must be accommodated on both the left and right sides of the liquid crystal display means, a large space is required on both the left and right sides of the liquid crystal display means.

  However, in recent gaming machines, the liquid crystal display means to be mounted is steadily increasing in size, and as a result, the space on both the left and right sides of the liquid crystal display means is gradually reduced. It is difficult to adopt such a drive door.

  In view of such a conventional problem, the present invention provides a sliding door type drive door disposed on the front side of the large display means that is difficult to secure a sufficient space on the left and right. It is an object of the present invention to provide a gaming machine that can be moved between fully closed positions.

  In the present invention, a pair of left and right drive doors 41a and 41b disposed on the front side of the display means 30 so as to be movable in the left and right direction, and the drive doors 41a and 41b, the closed side edges 83a and 83b facing each other are displayed. A door opening / closing means 31 having a drive mechanism 40 that opens and closes between a fully closed position substantially abutting on the front side of the means 30 and a fully open position retracted on both the left and right sides of the display means 30; A game provided with pinion gears 138a and 138b meshing with left and right racks 94a and 94b respectively provided on the left and right drive doors 41a and 41b, and motors 113a and 113b for rotationally driving the pinion gears 138a and 138b. In the machine, the racks 94a and 94b protrude from the closing side edges 83a and 83b of the drive doors 41a and 41b toward the other side and are mutually connected. Are offset in the vertical direction, the pinion gear 138a, 138b are those that are engaged from the rear side while being positioned toward the rotation axis 137 in the vertical direction the rack 94a, with respect to 94b.

  According to the present invention, even when the drive doors 41a and 41b are in the fully open position, the racks 94a and 94b do not protrude outward, and the large-sized liquid crystal display means 30 that is difficult to secure a sufficient space on the left and right is provided. Despite being mounted, it is possible to move the sliding door type drive doors 41a, 41b arranged on the front side between the fully open position and the fully closed position.

  Further, in order to open and close the drive doors 41a and 41b at a high speed, it is necessary to increase the diameters of the pinion gears 138a and 138b to some extent. However, since the pinion gears 138a and 138b are arranged substantially horizontally, for example, liquid crystal display means The projecting dimension to the lower side of 30 can be reduced.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1-16 has illustrated one Embodiment which employ | adopted this invention for the pachinko machine. In FIG. 1, a gaming machine main body 1 includes a rectangular outer frame 2 and a front frame 3 pivotally attached to the front side of the outer frame 2 so as to be freely opened and closed. On the front side of the front frame 3, a glass door 4 and a front plate 5 are arranged vertically and are pivotally supported by the front frame 3 so as to be freely opened and closed.

  On the front side of the front plate 5, an upper plate 6 for storing game balls for launch is arranged, and on the lower side of the front plate 5 and on the front side of the front frame 3, a lower plate 7 for storing extra balls is arranged. . On one side of the lower plate 7, for example, on the right side, a launching handle 8 of launching means (not shown) for launching a game ball is provided in a protruding manner on the front side of the front frame 3.

  A game board 21 is detachably attached to the back side of the front frame 3 so as to correspond to the rear side of the glass door 4. On the front side of the game board 21, a guide rail 22 for guiding a game ball launched from the launching means is annularly mounted, and a center case 24 and a normal symbol start are provided in a game area 23 inside the guide rail 22. Various game parts such as means 25, special symbol starting means 26, large winning means 27, and normal winning means 28 are arranged.

  As shown in FIG. 2, the center case 24 has a liquid crystal display means (display means) 30 constituting a special effect symbol display means 29, a door opening / closing means 31 capable of opening and closing the front side of the liquid crystal display means 30, and a normal opening / closing means 31. A symbol display means 32, a special symbol display means 33, a normal reserved number display means 34, a special reserved number display means 35, a special game state display means 36, and the like are provided.

  The normal symbol display means 32 is for variably displaying the normal symbol, and is composed of, for example, two light emitters (for example, LEDs) corresponding to two types of normal symbols “O” and “X”. On condition that the normal symbol starting means 25 composed of a gate or the like detects a game ball, the two illuminants blink alternately for a predetermined time, and the hit judgment disturbance acquired when the normal symbol starting means 25 detects the game ball. When the numerical value matches a predetermined hit determination value, the “○” side light emitter corresponding to the hit mode emits light, and in other cases, the “×” side light emission corresponding to the off mode The blinking ends when the body emits light.

  When the normal symbol starting means 25 detects a game ball during the fluctuation display of the normal symbol display means 32, the hit determination random number value acquired at the time of detection detects a predetermined upper limit reserved number, for example, four Is stored as a limit, and for example, the normal holding number display means 34 made of the same number of light emitters as the upper limit holding number displays the storage number of random numbers for hit determination (hereinafter, the normal holding number) by the number of light emission, The player is informed of the number of normally reserved items at that time.

  The special symbol starting means 26 is composed of a variable-actuated electric tulip or the like having a pair of left and right open / close claws 26a that can be freely opened and closed, and is disposed below the center case 24. When a later stop symbol becomes a hit state and a normal profit state occurs, the opening / closing claw 26a is operated in an open state for a predetermined time.

  The special symbol display means 33 is composed of one or a plurality of display means such as a seven-segment type capable of variably displaying one special symbol, for example, and the special symbol starting means 26 detects the game ball. If the special symbol is displayed in a variable condition for a predetermined time, and the jackpot determination random number value acquired when the special ball starting means 26 detects the game ball matches the predetermined jackpot determination value, the predetermined jackpot mode is used. In other cases, it stops in a disengagement mode.

  For example, 10 kinds of numerical symbols “0” to “9” and symbol symbol “−” are used as the special symbols, “0” to “9” are set to the big hit mode, and “−” is set to the off mode. Has been.

  Further, when the special symbol starting means 26 detects a game ball during the variation display of the special symbol, the jackpot determination random number obtained at the time of detection is stored up to a predetermined upper limit reserved number, for example, four. In addition, for example, the special reserve number display means 35 made up of the same number of light emitters as the upper limit reserved number displays the number of stored jackpot determination random number values (hereinafter referred to as special reserve number) by the number of emitted lights, and the special reserve at that time The number is notified to the player.

  The special game state display means 36 is for displaying the occurrence and the type of special game states such as so-called probability change and time reduction, for example, two pieces corresponding to two types of special game states of “probability change” and “time reduction”. When the special gaming state occurs after the end of the special profit state (bonus state) that occurs based on the special symbol after the variation of the special symbol display means 33 becomes a jackpot mode, One of the light emitters emits light corresponding to the type of the special game state.

  The effect special symbol display means 29 displays the effect special symbols variably in time synchronization with the special symbol change display by the special symbol display means 33, and one or more, for example, three effects in the left-right direction. The special symbol is configured to be variably displayed on the display screen 30a of the liquid crystal display means 30 together with various effect images, for example, and on the condition that the special symbol starting means 26 detects a game ball, the special symbol is simultaneously started to change. The special effect symbols are started in accordance with a predetermined change pattern, and the special effect symbols are stopped in a predetermined order such as left, right, and middle so that the special symbols are stopped at the same time as the special symbols are stopped.

  For example, 10 kinds of numerical symbols from “0” to “9” are used as the special effects designs, and all three symbols such as “6, 6, 6” and “7, 7, 7” are all in the same pattern. The thing is a big hit mode, and the one with different at least one pattern is the off mode.

  In addition, the stop symbol after the change of the effect special symbol by the effect special symbol display means 29 becomes a jackpot mode consisting of the same number symbol as the special symbol when the special symbol by the special symbol display means 33 stops in the jackpot mode, When the special symbol stops in a detaching manner, it becomes an arbitrary detaching manner. For example, when the special symbol stops at “7”, the special production symbol stops at “7 / 7.7”, and when the special symbol stops at “−”, the special production symbol becomes “3.4. It stops in any disengagement mode such as “5”.

  The special winning means 27 is a variable actuating type equipped with an opening / closing plate 27a that can be changed between an open state advantageous to the player and a closed state disadvantageous to the player, and the special symbol display means 33 after the change of the special symbol. When a special profit state (a big hit state) occurs based on the fact that the game is a big hit mode, the open / close plate 27a is opened to the front side for a predetermined time, and the game ball dropped on the open plate 27a is awarded to the inside. ing.

  The big winning means 27 is provided with an opening / closing plate when a predetermined condition is satisfied such that a predetermined time (for example, 28 seconds) elapses from the opening or a predetermined number (for example, ten) of game balls are won within the predetermined time. 27a is closed and the opening operation is repeated a predetermined number of times (for example, 15 times).

  The door opening / closing means 31 opens and closes the front side of the display screen 30a of the liquid crystal display means 30 by a double-sliding door type door, and is movable to the front side of the liquid crystal display means 30 as shown in FIGS.

  The door opening / closing means 31 configured as described above has the drive doors 41a and 41b and the driven doors 42a, 42b, 43a and 43b mounted between the lower drive unit 81 and the upper upper rail unit 82. The upper case body 62 is mounted from the front side. At this time, the pinion gears 138a, 138b and the like are fitted into the opening 71 on the upper case body 62 side from the front side, and the gear covers 70a, 70b are arranged near the upper sides of the pinion gears 138a, 138b, respectively. .

  As shown in FIGS. 3 and 4, the back structure 45 is detachably mounted on the front side thereof with a transparent plate 171 that substantially covers the front side of the door opening / closing means 31, and then the display window 67 is located on the front side of the front structure 44. It is mounted on the back side of the game board 21 so as to correspond to the rear side of the display window 46. At this time, the lower cover body 63 on the back structure 45 side is arranged so as to cover the rear side of the special symbol starting means 26 provided on the game board 21 side.

  Next, the opening / closing operation of the door opening / closing means 31 will be described with reference to FIG. In the normal state, the door opening / closing means 31 is a door fully open state in which the drive doors 41a and 41b and the driven doors 42a, 42b, 43a and 43b are all in the fully open position and the front side of the display screen 30a of the liquid crystal display means 30 is all open. (FIG. 16A).

  In this fully opened state, as shown in FIG. 3, the left and right three doors overlap each other in the front-rear direction, that is, on the side of the display screen 30a, that is, between the ball drop passages 48a and 48b and the light emitting panel 69. It becomes the state accommodated in between. In this door fully open state, the light from the light emitter 69b of the light emitting panel 69 is visible from the front side through the ball drop passages 48a and 48b and the door part 90 of each door.

  In this door fully open state, the drive doors 41a and 41b have their open side ends substantially in contact with the opening direction restricting portions 120a and 120b, and the driven doors 42a, 42b, 43a and 43b have their open side ends in the open direction. While being substantially in contact with the restriction portions 154a and 154b, the detected portions 98a and 98b of the drive doors 41a and 41b are detected by the position detection switches 130a and 130b, respectively.

  At this time, the interlocking protrusions 92 of the second driven doors 43a and 43b and the first driven doors 42a and 42b are fitted from the rear side into the interlocking guide grooves 93 of the first driven doors 42a and 42b and the drive doors 41a and 41b, respectively. In addition, it is positioned closest to the closed end 93a.

  For example, when the change of the effect special symbol on the effect special symbol display means 29 is started, a change pattern accompanying the operation of the door opening / closing means 31 is detected as the change pattern, and accordingly, the door from the game control means (not shown) is detected. When a closing command for the opening / closing means 31 is output, a drive command in the closing direction is transmitted to each motor 113a, 113b by an effect control means (not shown) for controlling the door opening / closing means 31. Thereby, the motor 113a on the left drive door 41a side rotates the pinion gear 138a counterclockwise in a plan view, and the motor 113b on the right drive door 41b side rotates the pinion gear 138b clockwise in a plan view, for example, at a constant speed. Then, the driving operation of the preset number of steps is started.

  When the drive operation in the closing direction of the motors 113a and 113b is started, the racks 94a and 94b meshing with the pinion gears 138a and 138b move and the racks 94a and 94b are fixed. The drive doors 41a and 41b start moving in the closing direction, respectively.

  When the driving doors 41a and 41b move in the closing direction, the interlocking projections 92 on the first driven doors 42a and 42b fitted in the interlocking guide grooves 93 of the driving doors 41a and 41b are moved relative to each other in the interlocking guide groove 93. When the drive doors 41a and 41b move approximately by one door, they abut against the open end 93b of the interlocking guide groove 93 (FIG. 16B). Thereafter, the first driven doors 42a and 42b are driven by the drive doors 41a and 41b via the interlocking protrusions 92 and both move in the closing direction.

  When the drive doors 41a and 41b and the first driven doors 42a and 42b further move by approximately one door, the second driven doors 43a and 43b on the side of the second driven doors 43a and 43b fitted in the interlocking guide grooves 93 of the first driven doors 42a and 42b. The interlocking projection 92 abuts on the open end 93b of the interlocking guide groove 93 (FIG. 16C). Therefore, after that, the second driven doors 43a and 43b also move in the closing direction together with the drive doors 41a and 41b and the first driven doors 42a and 42b.

  When the drive doors 41a and 41b come to a position just before the fully closed position, as shown in FIG. 9, the inclined surfaces 99a of the riding protrusions 99 projecting from the lower surfaces of the driven parts 86a and 86b The sliding protrusion 99 comes into sliding contact with the inclined surface 131 a of the pushing protrusion 131 on the 133 side, and rides on the upper side of the pushing protrusion 131. Thereby, the drive doors 41a and 41b are pushed up on the side on which the ride-up protrusion 99 is provided, that is, the rear side (open side) in the closing direction, and the upper end sides are swung in a direction approaching each other to correct the inclination. The door opening / closing means 31 is in a door fully closed state in which the front side of the display screen 30a of the liquid crystal display means 30 is covered by the drive doors 41a, 41b and the driven doors 42a, 42b, 43a, 43b. (FIG. 16D).

  On the other hand, when the door opening / closing means 31 is in the fully closed state (FIG. 16 (d)), for example, when a command to open the door opening / closing means 31 is output from the game control means, the effect control means applies the motors 113a and 113b. A drive command in the opening direction is transmitted. Thereby, each motor 113a, 113b starts the drive operation of the preset number of steps in the direction opposite to the time of closing, respectively.

  When the drive operation in the opening direction of the motors 113a and 113b is started, the drive doors 41a and 41b start moving in the opening direction via the pinion gears 138a and 138b and the racks 94a and 94b, respectively.

  When the driving doors 41a and 41b move in the opening direction, the interlocking protrusions 92 on the first driven doors 42a and 42b fitted in the interlocking guide grooves 93 of the driving doors 41a and 41b are relatively moved in the interlocking guide groove 93. When the drive doors 41a and 41b move approximately one door, they abut against the closing end 93a of the interlocking guide groove 93 (FIG. 16E). Thereafter, the first driven doors 42a and 42b are driven by the drive doors 41a and 41b via the interlocking protrusions 92 and both move in the opening direction.

  When the drive doors 41a and 41b and the first driven doors 42a and 42b further move by approximately one door, the second driven doors 43a and 43b on the side of the second driven doors 43a and 43b fitted in the interlocking guide grooves 93 of the first driven doors 42a and 42b. The interlocking protrusion 92 abuts on the closing side end portion 93a of the interlocking guide groove 93 (FIG. 16 (f)). Therefore, after that, the second driven doors 43a and 43b also move in the opening direction together with the drive doors 41a and 41b and the first driven doors 42a and 42b.

  When all the doors reach the fully open position (FIG. 16G), the detected portions 98a and 98b of the drive doors 41a and 41b are detected by the position detection switches 130a and 130b, respectively, and the motors 113a and 113b are opened. Is stopped.

  The production control means causes the door opening / closing means 31 to perform a predetermined initial operation at a predetermined timing such as when the power of the gaming machine main body 1 is turned on to confirm the operation. In this initial operation, for example, the motors 113a and 113b are operated in the closing direction and the opening direction, and it is confirmed whether or not the position detection switches 130a and 130b are normally turned ON / OFF.

  Further, when the motors 113a and 113b are driven in the opening direction, for example, the effect control means uses the position detection switches 130a and 130b even if the operation amount of the motors 113a and 113b exceeds a predetermined maximum number of steps (for example, 150 steps). If there is no detection, a predetermined retry operation is performed, and if there is still no detection by the position detection switches 130a and 130b, it is determined that the state is abnormal.

  In this retry operation, for example, the motors 113a and 113b are operated in a predetermined number of steps (for example, 20 steps) in the closing direction and a predetermined number of steps (for example, 100 steps) in the opening direction that is larger than the closing direction.

  If it is determined that the state is abnormal, the fact may be notified by display on the liquid crystal display means 30, sound, lamps, or the like, or without the notification, the special design display means 29 may cause the drive doors 41a, 41b and You may make it produce | present by displaying the moving image which the door substantially the same as the driven doors 42a, 42b, 43a, 43b opens and closes.
