Description

  The present invention relates to a gaming machine such as a pachinko machine or a slot machine, and more particularly to a gaming machine including a movable body that falls by its own weight from a rising position to a falling position.

  Among the gaming machines represented by pachinko machines, a variable display device, a start winning opening, an attacker device, etc. are provided in the gaming area of the game board, and the game balls launched toward the gaming area have won the starting winning opening. In response to this, there are many models in which electronic lottery is performed, and the variable display device performs variable display and stoppage of symbols based on the lottery result. The lottery result of the electronic lottery has a win and a loss. When the lottery result is a win, a specific symbol is displayed on the display screen of the variable display device, and the normal mode is switched to the special game mode. In this special game mode, the opening / closing door of the attacker device opens to expose the grand prize opening, so that it becomes easy for a game ball to enter the exposed big prize opening and the player can acquire many prize balls. .

  In this type of pachinko machine, a movable body whose movable mode can be changed is arranged at an arbitrary position around the variable display device, and the display content of the variable display device based on the lottery result of the electronic lottery and the movable mode of the movable body Movable accessory devices that are designed to produce a highly entertaining performance by combining these are widely adopted. The movable body is moved in various ways by a drive mechanism having a motor, gears, etc., and as an example, in the normal gaming state, the movable body is retracted to the raised position above the display screen of the variable display device. In addition, when a specific gaming state is reached, a movable accessory device that allows a movable effect to have an impact by performing a free fall from a rising position to a lowering position on the front side of the display screen is conventionally known. It is known (see, for example, Patent Document 1).

  In the movable accessory device disclosed in Patent Document 1, the movable body is guided by a guide member fixed to the game board so as to be movable in the vertical direction, and a rack extending in the vertical direction is provided on one side of the movable body. An operating gear pivotally supported on the guide member side with respect to the rack is engaged / released.

  In recent years, the movable performance by the movable body has been diversified more and more, for example, a movable display body is mounted on the back side of the movable body, and after the movable body is dropped by its own weight to the lowered position on the front side of the display screen, the front side of the display screen Thus, there is a demand to increase the impact level by projecting the movable display body from the lower end of the movable body, and by the movement of both the movable body and the movable display body. However, in such a case, even if the impact applied when the movable body falls due to its own weight is absorbed by the damper member, the movable display body is not lifted from the lower end of the movable body by the inertial force when the movable body stops at the lowered position. There arises a problem that it protrudes easily.

  The present invention has been made in view of the situation of the prior art as described above. The purpose of the present invention is to prevent the movable display mounted on the movable body from falling when the movable body falls by its own weight from the raised position to the lowered position. It is an object of the present invention to provide a gaming machine that can prevent malfunctions in preparation.

  In order to achieve the above object, a gaming machine according to the present invention includes a movable body capable of moving up and down between a raised position and a lowered position, and drop switching for dropping the movable body from the raised position to the lowered position by its own weight. Means, a stopper member that receives the movable body falling by its own weight and holds the movable body in the lowered position, a movable display body mounted on the movable body, and a drive mechanism that causes the movable display body to move in and out of the movable body, A guide member that guides a contact portion provided on a side portion of the movable display body in a vertical direction, a restriction member that can be engaged with and disengaged from the contact portion, and a spring member that elastically supports the restriction member at an initial position; When the movable body falls by its own weight, the contact portion contacts the restriction member, so that the restriction member moves downward from the initial position against the pulling force of the spring member. It is characterized by.

  In the gaming machine configured as described above, when the movable body mounted with the movable display body falls by its own weight from the raised position, the contact portion of the movable display body abuts on the regulating member during the fall, so that the spring member is Since the movement of both the movable display body and the movable body is braked by extending, it is possible to absorb an impact when the movable body that has fallen to the lowered position comes into contact with the stopper member. Inadvertent protrusion can be prevented.

  In the gaming machine configured as described above, the guide member is provided with a guide hole for guiding the regulating member in the vertical direction, and the regulating member receives the pulling force of the spring member at the initial position and is in contact with the upper end of the guide hole. Until the contact portion comes into contact with the restriction member due to the falling weight of the movable body, the elastic force of the spring member does not act on the movable display body and the movable body, and the contact portion comes into contact with the restriction member. Since the spring member starts to extend, the movable body that has fallen by its own weight from the raised position can be braked gradually from the front side of the lowered position.

  According to the gaming machine of the present invention, when the movable body falls by its own weight from the raised position to the lowered position, it is possible to prevent the movable display body mounted on the movable body from inadvertently malfunctioning.

  The mounting base 33 includes a spiral shaft 41 extending in the vertical direction, which is a constituent member of the lifting mechanism 34, a motor 42 that rotationally drives the spiral shaft 41 around its axis, and an operation that is movable along the axial direction of the spiral shaft 41. A body 43, a guide rail 44 disposed on the opposite side of the operating body 43 with the spiral shaft 41 interposed therebetween, and a photo interrupter 45 for detecting the position of the operating body 43 are supported. A moving block 44a coupled to the upper and lower ends is fitted to be movable up and down.

  A gear 46 is fixed to the lower end portion of the spiral shaft 41, and the gear 46 meshes with a gear 47 fixed to the rotating shaft of the motor 42. The spiral shaft 41 is screwed with an elevating member 48 that is a nut body. Since the elevating member 48 is restricted in movement in the rotational direction by the mounting base 33, the elevating member 48 is accompanied by the rotation of the spiral shaft 41. Can be moved in the axial direction. On the outer wall surface of the elevating member 48, a first pressing portion 48a and a second pressing portion 48b are formed to project in opposite directions, and the second pressing portion 48b is engaged with and disengaged from the second engaging portion 37b of the movable body 37.

Then, as shown in FIG. 13B, the first pressing portion 48 a comes into contact with the receiving portion 43 a and pushes down the operating body 43 against the spring force of the spring 49. As a result, the downward movement of the actuating body 43 is converted into the leftward movement of the lock piece 51 via the link member 50, and the lock piece 51 moves from the lock position to the unlock position. Since the engaging portion 37a is disengaged, the upper movable body unit 32 falls by its own weight toward the lowered position, and then collides with the stopper member 36 and stops at the lowered position.

  When returning the upper movable body unit 32 that has fallen to the lowered position to the raised position, when the motor 42 is reversed and the spiral shaft 41 is rotated in the opposite direction, as shown in FIG. Since the elevating member 48 rises along the axial direction of the spiral shaft 41, the operating body 43 moves upward by the spring force of the spring 49, and accordingly, the lock piece 51 moves from the unlocked position toward the locked position. . Further, when the elevating member 48 moves to the upper end side of the spiral shaft 41, the second pressing portion 48 b of the elevating member 48 contacts the second engaging portion 37 b of the movable body 37 during the movement, and thereafter the elevating member 48 and The upper movable body unit 32 rises together toward the raised position. Then, after the first engaging portion 37a pushes away the lock piece 51 on the front side of the raised position, the lock piece 51 is placed on the lower surface of the first engaging portion 37a when the upper movable body unit 32 moves to the raised position. Because of the contact, the upper movable body unit 32 is again locked in the raised position by the lock piece 51 as shown in FIG.

  Next, the shock absorbing mechanism of the upper movable body unit 32 will be described. As shown in FIGS. 14 and 15, the guide member 35 fixed to the right side wall portion of the support base 31 has a guide hole 52a extending in the vertical direction. A guide base 52 provided, a spacer member 53 provided with a partition wall 53a, a guide main body 54 integrated with the guide base 52 via the spacer member 53, and a regulation capable of moving up and down along the guide hole 52a. A member 55 and a tension coil spring 56 that urges the regulating member 55 upward are provided. The guide member 35 is formed with two guide grooves S1 and S2 extending in the vertical direction across the partition wall 53a of the spacer member 53, and the restricting member 55 is disposed in the back guide groove S2. The regulating member 55 is provided with a shaft portion 55a that passes through the guide hole 52a and protrudes to the back side of the guide base 52, and the lower end portion of the tension coil spring 56 that is hooked on the guide base 52 is the relay member 57.

  When the upper movable body unit 32 is locked at the raised position, as shown in FIG. 16A, the contact portion 38a of the first movable display body 38 is separated above the regulating member 55 held at the initial position. In the initial position, the shaft portion 55a of the restricting member 55 receives the pulling force of the tension coil spring 56 and is in contact with the upper end of the guide hole 52a.

  When the upper movable body unit 32 falls by its own weight toward the lowered position from this state, the contact portion 38a of the first movable display body 38 is in the middle of the fall, as shown in FIGS. Since the tension coil spring 56 begins to expand at this point, a brake is applied to the dropping speed of the entire upper movable body unit 32 including the movable body 37 and the first and second movable display bodies 38 and 39. When the lower surface of the movable body 37 abuts against the stopper member 36, the upper movable body unit 32 stops at the lowered position, but at this point in time, as shown in FIGS. Therefore, the impact when the movable body 37 abuts against the stopper member 36 can be absorbed by the spring force of the tension coil spring 56.

  Thus, the first movable display body until the contact portion 38a of the first movable display body 38 comes into contact with the regulating member 55 as the upper movable body unit 32 falls due to its own weight drop, that is, in the initial stage of the own weight drop. The spring force of the tension coil spring 56 does not act on the movable body 37 or the movable body 37, and the tension coil spring 56 begins to expand when the abutting portion 38a abuts against the regulating member 55 in the middle of dropping. The dropped upper movable body unit 32 can be gradually braked from the front side of the lowered position, and the first movable display body 38 will inadvertently protrude from the lower end of the movable body 37 due to the impact at the time of dropping. Can be suppressed.

A protective cover 67 fixed to the mounting base 62 is provided so as to cover it. In FIG. 22, the mounting base 62 and the protective cover 67 are shown in a state where they are removed for easy understanding.

  A motor 63 that is a drive source of the opening / closing drive mechanism 40 is mounted on an attachment base 62 fixed to the movable body 37, and the rotation of the motor 63 is transmitted to the cam gear 65 via the reduction gear train 64. An engagement protrusion 65 a is provided at a portion protruding from the outer peripheral surface of the cam gear 65, and the engagement protrusion 65 a is inserted into a long hole 38 c of the first movable display body 38 via a cylindrical roller 68. Has been inserted. The long holes 38c extend in the horizontal direction (left-right direction) orthogonal to the extending direction of the first rack portion 38b. The long holes 38c and the first rack portion 38b are provided in the sheet metal portion of the first movable display body 38. It has been.

  The engagement protrusion 65a slides in the elongated hole 38c as the cam gear 65 rotates, and the rotational movement of the cam gear 65 thereby causes the first movable display body 38 to move in a vertical line. Converted into movement. Although details will be described later, at that time, the engaging protrusion 65a moves in the long hole 38c so as to cross the vertical line P passing through the rotation center of the gear 65 with the cam.

  The first rack portion 38b of the first movable display body 38 and the second rack portion 39b of the second movable display body 39 extend in parallel in the vertical direction, and the first rack portion 38b and the second rack portion 39b are pinned to each other. A certain synchronous gear 66 is engaged. The first rack portion 38b, the second rack portion 39b, and the synchronization gear 66 are a power transmission portion (rack and / or rack) that transmits the vertical movement of the first movable display body 38 to the vertical movement in the opposite direction of the second movable display body 39. The synchronous gear 66 and the cam gear 65 are stacked in the direction of the rotation axis. That is, the plane on which the first rack portion 38b, the second rack portion 39b, and the synchronous gear 66 move is displaced in the front-rear direction with respect to the plane on which the reduction gear train 64 and the cam gear 65 are arranged. The opening / closing drive mechanism 40 is prevented from being enlarged in the plane direction by overlapping the arrangement space in the front-rear direction.

  The operation of the opening / closing drive mechanism 40 configured as described above will be described with reference to FIGS. FIG. 23 mainly shows the positional relationship between the cam gear 65 and the long hole 38c, and FIG. 24 mainly shows the positional relationship of the synchronization gear 66 with respect to the first rack portion 38b and the second rack portion 39b.

  When the first movable display body 38 and the second movable display body 39 are in the initial position where they overlap each other on the back surface side of the movable body 37, as shown in FIG. As shown in FIG. 24 (a), the synchronization gear 66 is engaged with the lowermost portion of the first rack portion 38b and the upper portion of the second rack portion 39b. Here, if the vertical line passing through the rotation center of the gear 65 with the cam is P, the engagement protrusion 65a is engaged with the elongated hole 38c at a position on the right side of the vertical line P, so the first movable display body 38 is engaged. Even if a downward force is applied from the outside, the external force is blocked by the right end of the long hole 38c and the engaging portion of the engaging protrusion 65a, and the first movable display 38 and the second movable display 39 Are locked in overlapping closed states.

  In this state, the motor 63 is rotated in one direction and transmitted to the reduction gear train 64, and when the cam gear 65 that meshes with the final gear of the reduction gear train 64 rotates counterclockwise in the drawing, the engagement protrusion 65a. Moves in the long hole 38c from the right end to the left end in the figure, and as shown in FIG. 23 (b), the locked state is first released when the engaging protrusion 65a exceeds the vertical line P. Thereafter, the rotation of the gear 65 with the cam is converted into a downward movement of the first movable display body 38. As a result, the first movable display body 38 is lowered along the outer guide rail 61, and the downward movement of the first rack portion 38 b of the first movable display body 38 is directed upward of the second rack portion 39 b via the synchronization gear 66. 24 (b), the first movable display body 38 and the second movable display body 39 start the opening operation, and the first movable display body 38 is at the lower end of the movable body 37. The second movable display body 39 starts to protrude upward from the upper end of the movable body 37.

  When the long hole 38c of the first movable display body 38 is lowered to a position exceeding the rotation center of the cam-equipped gear 65 in this way, the engaging protrusion 65a that has been moving toward the left end in the long hole 38c until then. When the motor 63 is stopped at the time when the engaging projection 65a moves to the right end of the long hole 38c as shown in FIG. The 2nd movable display body 39 will be in an open state. At this time, the projection amounts of the first movable display body 38 and the second movable display body 39 projecting from the movable body 37 are maximized, and as shown in FIG. 24C, the synchronization gear 66 is disposed at the maximum of the first rack portion 38b. The upper part meshes with the lowermost part of the second rack part 39b.

  If the motor 63 is rotated in the other direction when the first movable display body 38 and the second movable display body 39 are in the open state, the opening / closing drive mechanism 40 performs an operation opposite to the above, thereby The movable display body 38 and the second movable display body 39 return to the initial position where they overlap each other on the back side of the movable body 37, and both the 38 and 39 are again in the closed state in which the opening operation is locked.

  Next, the second movable accessory device 28 will be described in detail with reference to FIGS. 25 to 29. The second movable accessory device 28 includes a base member 70 as an installation member fixed to the game board 6. The lower movable body unit 71 supported by the base member 70 so as to be movable up and down, a pair of tension springs 72 that elastically urge the lower movable body unit 71 upward, and fixed to the left side wall portion of the base member 70 The auxiliary plate 73, the guide rail 74 fixed to the right side wall of the base member 70, a pair of motors 75 mounted on the base member 70, and a pair of gear units 76 that rotate using these motors 75 as a drive source. And a torsion spring 77 for assisting the pulling force of the pair of tension springs 72.

  A guide roller 71 a is provided at the left end portion of the lower movable body unit 71, and a rectangular guide portion 71 b is provided at the right end portion of the lower movable body unit 71. Then, the guide roller 71a is inserted between the base member 70 and the auxiliary plate 73 so as to be movable up and down, and the guide portion 71b is slidably fitted to the guide rail 74, whereby the lower movable body unit 71 is raised. It is supported by the base member 70 so that it can move up and down between the position and the lowered position. A pair of long holes 71c are provided on the back surface of the lower movable body unit 71, and these long holes 71c extend in the horizontal direction (left-right direction). Although not particularly illustrated, inside the lower movable body unit 71, a circuit board on which a plurality of LEDs for emitting display parts such as characters and logo marks formed on the front surface are mounted, A design plate 81 (see FIG. 31) simulating the lower part of the letter “V” is stored, and a motor 82 for moving the design plate 81 up and down is installed on the back surface of the lower movable body unit 71. .

  The pair of gear units 76 includes a support plate 78 that supports the motor 75, a reduction gear train 79 that is pivotally supported on the back surface of the support plate 78, and a swing gear 80 that meshes with the final gear of the reduction gear train 79. The shaft portion 80 a provided in the swing gear 80 is slidably inserted into the corresponding long hole 71 c of the lower movable body unit 71. The motor 75, the gear unit 76, the long hole 71c, and the like constitute a drive mechanism that moves the lower movable body unit 71 up and down.

  The torsion spring 77 has a pair of arm portions 77 b and 77 c protruding from both ends of the cylindrical winding portion 77 a, and one arm portion 77 b is a protrusion 71 d provided on the back surface of the lower movable body unit 71. The other arm 77c is hooked on a protrusion 70a provided on the front surface of the base member 70. However, the winding part 77a of the torsion spring 77 is in a free state that is not fixed to any of them, and the position of the winding part 77a moves up and down in accordance with the raising / lowering operation of the lower movable body unit 71 as will be described later. Thus, the direction of the urging force of the torsion spring 77 acting on the lower movable body unit 71 is changed.

  The ascending / descending operation of the second movable accessory device 28 configured in this manner will be described with reference mainly to FIG.

  FIG. 25 shows a state in which the lower movable body unit 71 is stopped at the lowered position. In this case, as shown in FIG. 28 (a), the pair of tension springs 72 extend to a state where the total length is maximized. Thus, a large pulling force acting upward from these tension springs 72 acts on the lower movable body unit 71. At this time, the tip (projection 71d) of one arm 77b of the torsion spring 77 is located below the tip (projection 70a) of the other arm 77c, and the lower movable body unit 71 is moved from the torsion spring 77 to the lower movable body unit 71. On the other hand, a biasing force acting substantially horizontally (in the direction of arrow A) is acting.

  When the pair of motors 75 are rotated in one direction in this state, the rotations of the motors 75 are transmitted to the rotation of the swing gear 80 via the reduction gear train 79, and the shaft portion 80a of the swing gear 80 corresponds accordingly. Since the elongated hole 71c moves from the outer end portion toward the inner end portion, the rotation of the swing gear 80 is converted into an upward linear motion of the lower movable body unit 71. As a result, the lower movable body unit 71 rises while receiving a large tensile force of the tension spring 72, and the direction of the urging force from the torsion spring 77 to the lower movable body unit 71 as shown in FIG. Gradually changes upward (in the direction of arrow B).

  When the rotation of the motor 75 is further continued, the shaft portion 80a of the swing gear 80 moves from the inner end portion of the elongated hole 71c toward the outer end portion, and accordingly, the lower movable body unit 71 approaches the raised position. Then, the total length of the pair of tension springs 72 is gradually shortened. Then, as shown in FIG. 29, when the lower movable body unit 71 rises to the raised position, the pulling force of the tension spring 72 that attempts to lift the lower movable body unit 71 at that time is minimized. The opening angle of the arms 77b and 77c is maximized, and the urging force of the torsion spring 77 is also reduced. However, as shown in FIG. 28 (c), since the direction of the urging force from the torsion spring 77 to the lower movable body unit 71 changes almost upward (arrow C direction) at this time, the lower movable body unit 71 is assisted by the upward biasing force of the torsion spring 77, and can move to the raised position while maintaining the rising speed.

  When the lower movable body unit 71 is in the raised position, when the motor 75 is rotated in the other direction, an operation opposite to the above is performed, and the lower movable body unit 71 is a spring of the tension spring 72 and the torsion spring 77. In this case, the lower movable body unit 71 having a large total weight moves to the lowering position while receiving its own weight. Therefore, the lower movable unit 71 is moved downward by the tension spring 72 and the torsion spring 77. The descending speed of the movable body unit 71 does not slow down.

  In the gaming machine (pachinko machine) configured as described above, the upper movable body unit 32 of the first movable accessory device 27 and the lower movable body unit 71 of the second movable accessory device 28 are usually driving sources. As shown in FIG. 4, the upper movable body unit 32 is held at an upper position of the variable display device 30, and the lower movable body unit 71 is a lower position of the variable display device 30. Is held in.

  FIG. 13A shows the non-operating state of the upper movable body unit 32. As described above, the upper movable body unit 32 is locked in the raised position by the lock piece 51 in this non-operating state. At this time, as shown in FIG. 16A, the abutting portion 38a of the first movable display body 38 is at a separation position above the regulating member 55 held at the initial position, and the regulating member 55 is at the initial position. The shaft portion 55a is in contact with the upper end of the guide hole 52a under the tensile force of the tension coil spring 56.

  In this state, when the motor 42 that is a drive source of the lifting mechanism 34 is rotated in one direction, the lifting member 48 is lowered along the axial direction of the spiral shaft 41, and as shown in FIG. Since 48a abuts on the receiving portion 43a and pushes down the operating body 43 against the spring force of the spring 49, the lock piece 51 moves from the lock position to the unlock position. As a result, the engagement between the lock piece 51 and the first engaging portion 37a is released, and the upper movable body unit 32 falls by its own weight toward the lowered position, and then collides with the stopper member 36 and stops at the lowered position.

  Thus, when the upper movable body unit 32 falls by its own weight toward the lowered position, the contact portion 38a of the first movable display body 38 is moved to the upper surface of the regulating member 55 during the fall as shown in FIG. Since the tension coil spring 56 begins to expand at this point, the brake is applied to the drop speed of the entire upper movable body unit 32 including the movable body 37 and the first and second movable display bodies 38 and 39. When the lower surface of the movable body 37 abuts against the stopper member 36, the upper movable body unit 32 stops at the lowered position, but as shown in FIG. Therefore, the impact when the movable body 37 comes into contact with the stopper member 36 can be absorbed by the spring force of the tension coil spring 56.

  Further, when the upper movable body unit 32 is locked at the raised position, the first movable display body 38 and the second movable display body 39 are in the initial positions overlapping on the back side of the movable body 37, and FIG. As shown in FIG. 4, the engaging projection 65a of the cam gear 65 is engaged with the right end of the elongated hole 38c in the initial position, so that the first movable display 38 and the second movable display 39 overlap each other. Locked in the closed state. Accordingly, the upper movable body unit 32 falls by its own weight toward the lowered position while maintaining this locked state, so that the first movable display body 38 and the second movable body are affected by an impact when the movable body 37 contacts the stopper member 36. The display body 39 is not inadvertently opened.

  After the upper movable body unit 32 falls by its own weight from the raised position and stops at the lowered position, when the motor 75 provided in the second movable accessory device 28 is rotated in one direction, FIGS. As shown in (c), the lower movable body unit 71 moves to the ascending position while receiving a large pulling force of the tension spring 72. During the movement, the lower movable body unit 71 is attached to the lower movable body unit 71. By changing the direction of the force upward, the lower movable body unit 71 moves to the ascending position while maintaining the ascending speed. As a result, as shown in FIG. 30, the upper movable unit 32 of the first movable accessory device 27 dropped from above and the lower movable unit 71 of the second movable accessory device 28 protruding from below are variably displayed. It is exposed in front of the display screen 30a of the device 30.

  Thereafter, when the motor 42 that is the drive source of the elevating mechanism 34 is rotated by a predetermined amount in the opposite direction, the elevating member 48 is raised along the axial direction of the spiral shaft 41 as shown in FIG. During the movement, the second pressing portion 48b of the elevating member 48 contacts the second engaging portion 37b of the movable body 37, so that the upper movable body unit 32 moves upward by a predetermined amount from the lowered position, and the upper movable body. A space is secured between the unit 32 and the lower movable body unit 71.

  When the motor 63 that is the drive source of the opening / closing drive mechanism 40 is rotated in one direction in this state, as shown in FIG. 23 (b), the engagement protrusion 65a of the gear 65 with the cam moves through the long hole 38c in the right end in the figure. Since the locked state is released when the engagement protrusion 65a exceeds the vertical line P during the movement, the rotation of the cam-equipped gear 65 rotates the first movable display body 38. Converted to downward movement. As a result, the first movable display body 38 is lowered along the outer guide rail 61, and the downward movement of the first rack portion 38 b of the first movable display body 38 is directed upward of the second rack portion 39 b via the synchronization gear 66. 24 (b), the first movable display body 38 and the second movable display body 39 start the opening operation, and the first movable display body 38 is at the lower end of the movable body 37. The second movable display body 39 starts to protrude upward from the upper end of the movable body 37.

  Then, as shown in FIGS. 23 (c) and 24 (c), when the motor 63 is stopped when the protrusion amounts of the first movable display body 38 and the second movable display body 39 become maximum, the first movable display body 38 and the second movable display body 39 are stopped. The display body 38 and the second movable display body 39 are in an open state protruding from both upper and lower ends of the movable body 37. Further, when the motor 82 mounted on the lower movable body unit 71 is started and the design plate 81 is lowered simultaneously with the opening operation of the first movable display body 38 and the second movable display body 39, as shown in FIG. Further, a design imitating the letter “V” of the alphabet is exposed from the upper movable body unit 32 and the lower movable body unit 71, and the letter “V” meaning “win” is displayed in front of the display screen 30a. appear.

  Note that the movable mode of the first movable accessory device 27 and the second movable accessory device 28 is not limited to the above-described embodiment, and the first movable accessory device 27 and the second movable accessory device 28 are continuously or independently. It is also possible to operate. For example, after the upper movable body unit 32 of the first movable accessory device 27 is dropped by its own weight from the raised position to the lowered position, the first movable display body 38 and the second movable display body 39 are maintained in the locked state while maintaining the locked state. The movable body unit 32 may be returned to the raised position. In this case, as shown in FIG. 13C, the elevating member 48 is raised along the axial direction of the spiral shaft 41 by the rotation of the motor 42, and the second pressing portion 48b of the elevating member 48 is movable during the movement. 37, when the elevating member 48 and the upper movable body unit 32 are raised toward the raised position by the further rotation of the motor 42, the lock piece 51 of the first engaging portion 37a is brought into contact with the second engaging portion 37b. Since it abuts on the lower surface, the upper movable body unit 32 can be locked again in the raised position by the lock piece 51 as shown in FIG. Alternatively, only the lower movable body unit 71 of the second movable accessory apparatus 28 may be moved up and down while the upper movable body unit 32 of the first movable accessory apparatus 27 is held in the raised position.

  As described above, in the gaming machine (pachinko machine) according to this embodiment, the upper movable body unit 32 mounted with the first movable display body 38 that moves downward on the back side of the movable body 37 falls from its raised position by its own weight. When this occurs, the abutting portion 38a of the first movable display body 38 abuts on the upper surface of the restricting member 55 during the fall, and the tension coil spring 56 begins to expand at this point. A brake is applied to the falling speed of the entire upper movable body unit 32 including the movable display bodies 38 and 39. When the lower surface of the movable body 37 abuts against the stopper member 36, the upper movable body unit 32 stops at the lowered position. At this time, the total length of the tension coil spring 56 is maximized. Can be absorbed by the spring force of the tension coil spring 56, and the first movable display body 38 is moved by the inertial force when the upper movable body unit 32 stops at the lowered position. Protruding from the lower end of the movable body can be prevented.

  In the gaming machine according to the present embodiment, the guide base 52 that is a constituent member of the guide member 35 is provided with the guide hole 52a that guides the restriction member 55 in the vertical direction. Since the portion 55 a receives the tensile force of the tension coil spring 56 and comes into contact with the upper end of the guide hole 52 a, the contact portion 38 a comes into contact with the regulating member 55 when the upper movable body unit 32 falls by its own weight. The elastic force of the tension coil spring 56 does not act on the first movable display body 38 and the movable body 37 until the tension coil spring 56 begins to expand when the contact portion 38a contacts the regulating member 55. The upper movable body unit 32 that has fallen with its own weight vigorously from the raised position can be gradually braked from the front side of the lowered position.

  In the above embodiment, the first movable display body 38 and the second movable display body 39 that can be opened and closed in the vertical direction are mounted on the back surface of the movable body 37 to form the upper movable body unit 32. Although the movable accessory device in which the body unit 32 falls by its own weight from the raised position to the lowered position has been described, the same effect is obtained even in the upper movable body unit 32 in which only the first movable display body 38 is mounted on the back surface of the movable body 37. There is an effect.

  Moreover, although the said embodiment demonstrated the case where the production | presentation actor unit by this invention was applied to the pachinko machine, it is also possible to apply to other game machines, such as a slot machine.
