Description

  The present invention relates to a gaming machine such as a pachinko machine or a slot machine provided with a movable body that can swing vertically.

  In recent years, pachinko machines and other gaming machines equipped with large-sized liquid crystal display means have become mainstream, and each company has been trying to differentiate it from other companies' products by means of staging images displayed on the liquid crystal display means. However, it has become difficult to sufficiently differentiate from other companies' products only by differentiation based on virtual effect images displayed on the liquid crystal display means. Therefore, in order to further enhance the effect by combining mechanical effects with image effects, for example, a device provided with a movable body in the vicinity of the liquid crystal display means has been developed (see Patent Document 1).

  In addition, this type of movable body tends to increase in size with a liquid crystal screen. However, when such a large movable body is operated in the vertical direction, for example, a small drive device cannot obtain a sufficient ascending force. There are many cases. Therefore, for example, in the invention described in Patent Document 1, a movable body can be smoothly raised even with a small driving device by providing a coil spring that assists the raising force by the driving device.

  As shown in FIG. 2, the movable unit 41 is substantially entirely hidden behind the upper decoration portion 33 on the front structure 21 side, and the front display surface 41a faces substantially downward from the front side. The rotating drum 44 is not visible, the display surface 41a faces forward at the lower position, and appears below the upper decorative portion 33, and the rotating drum 44 is visible from the front side.

  The rotary drum 44 has, for example, characters, figures, and other effects designs (not shown) printed on the outer peripheral surface thereof. For example, when the movable unit 41 is in the lower position, the rotation drum 44 is arranged in the movable box 43. It rotates by the drive of the drive means 45, and it stops in the state which orient | assigned the design for any effect to the front side.

  As described above, in the movable unit 41, the support shaft 46 is disposed on the upper side of the front end portion, and the center of gravity is on the rear side and the lower side with respect to the support shaft 46. It is biased in the direction of descending to the lower position side.

And a box 64.

  The rotation drive means 61 is arranged with its drive shaft 61a parallel to the support shaft 46 on the movable unit 41 side, that is, in the left-right direction. For example, the front end side of the drive shaft 61a projects into the interlocking box 64. In this state, it is detachably fixed to the outer surface side of the interlocking box 64. The rotation driving means 61 is arranged such that the drive shaft 61a is located at a predetermined distance from the support shaft 46 in a predetermined direction, for example, on the rear side.

  The interlocking means 62 includes a driving lever 65 fixed to the driving shaft 61a, a driven lever 66 detachably connected to the support shaft 46 on the movable unit 41 side, the driving lever 65 and the driven side. A connecting link 67 that connects the lever 66 is provided.

  The drive-side lever 65 is provided in a direction orthogonal to the drive shaft 61a. The shaft fixing portion 68 on one end side is fixed to the drive shaft 61a, and the drive shaft 61a and the support shaft 46 are parallel to the other end side. A driving side connecting shaft 69 is provided. Further, a detected portion 70 corresponding to the position detecting means 63 is provided on the drive side lever 65 so as to protrude in the radial direction of the drive shaft 61a.

  The driven lever 66 is provided in a direction orthogonal to the support shaft 46, and an interlocking shaft 71 coaxial with the support shaft 46 projects from one end side in the left-right direction, and the drive shaft 61a is provided on the other end side. In addition, a driven side connecting shaft 72 parallel to the support shaft 46 is provided. The driven lever 66 is rotatably supported at both ends of the interlocking shaft 71 by bearings 73 and 74 on the interlocking box 64 side. For example, the notched engagement is provided at one end of the interlocking shaft 71. The mating portion 75 is detachably engaged with the engaging portion 76 on the support shaft 46 side, so that it is connected to the support shaft 46 in the rotational direction.

  When the movable unit 41 is in the upper position, the driven lever 66 is substantially upward with respect to the support shaft 46 (FIG. 9A), and the driven lever 66 is directed backward from that position at a predetermined angle, for example, The movable unit 41 reaches the lower position when rotated about 75 degrees (FIG. 9B).

  Further, the driven lever 66 is provided with a protruding portion 77 parallel to the support shaft 46 between, for example, the interlocking shaft 71 and the driven side connecting shaft 72, for example, on one side in the left-right direction.

  The connection link 67 is arranged in a direction orthogonal to the drive shaft 61a and the support shaft 46, and one end side thereof is connected to the drive side connection shaft 69 on the drive side lever 65 side, and the other end side is connected to the driven side on the driven side lever 66 side. Each of the shafts 72 is rotatably connected.

  The relationship among the drive shaft 61a, the support shaft 46, and the drive side lever 65, the driven side lever 66, and the connection link 67 that connect them is set as follows. That is, when the movable unit 41 is in the upper position, the angle formed by the driven side connecting shaft 72, the driving side connecting shaft 69, and the driving shaft 61a is 180 degrees as shown in FIG. The angle formed by the driven side connecting shaft 72 and the driving side connecting shaft 69 is approximately 90 degrees. When the drive shaft 61a is driven from this state and the drive side lever 65 swings downward, the driven side lever 66 swings backward in conjunction with this, whereby the support shaft 46 and the driven side connection are connected. The angle formed by the shaft 72 and the drive side connecting shaft 69 gradually increases from about 90 degrees, so that the movable unit 41 reaches the lower position before the angle reaches 180 degrees as shown in FIG. 9B. It has become.

  The interlocking box 64 is constituted by a main body case 81 and a lid 82 that can be fitted in the axial direction of the support shaft 46, for example, and, for example, a rear structure via a projecting fixing portion 64a provided on the rear side. It is detachably fixed to the body 23.

  As shown in FIGS. 6 and 7, the main body case 81 includes a right side wall 83 disposed along the left side surface of the movable unit 41, and a front and rear front and rear projecting leftward along the outer periphery of the right side wall 83. The peripheral wall 84 is formed in a flat box shape whose left side is open, and a drive side lever 65, a driven side lever 66, a connecting link 67, a position detecting means 63, and the like are disposed therein.

  The right side wall 83 of the body case 81 has, for example, an outwardly recessed shaft fitting portion 85 on which one end side of the shaft fixing portion 68 on the driving side lever 65 side is rotatably fitted, and a driven side lever 66 side. A bearing 73 that rotatably holds the right end side of the interlocking shaft 71 is provided. The bearing portion 73 is a circular through hole corresponding to the interlocking shaft 71, and the interlocking shaft 71 passes through the bearing portion 73 and is connected to the support shaft 46 outside the interlocking box 64.

  The position detecting means 63 is constituted by, for example, a transmissive photosensor, and is mounted on the upper side of the drive shaft 61a via the substrate 86, for example. The position detection means 63 is arranged so as to detect the detected portion 70 on the drive side lever 65 side when the movable unit 41 comes to the upper position or the vicinity thereof, and the drive control means (not shown) detects this position detection. Based on the detection signal from the means 63, the rotation driving means 61 is driven and controlled.

  Further, in the main body case 81, there are provided a descending side restricting portion 87 for restricting the swing of the movable unit 41 at the lower position, and an ascending side restricting portion 88 for similarly restricting at the upper position. The descending side restricting portion 87 restricts the swing of the movable unit 41 at the lower position by restricting the swing of the driven lever 66. For example, the descending side restricting portion 87 projects inwardly from the lower peripheral wall 84a of the main body case 81. It is formed, and when the movable unit 41 comes to the lower position, the driven lever 66 is brought into contact with the movable unit 41 so as to regulate the swinging thereof.

  The ascending-side restricting portion 88 restricts the swing of the movable unit 41 at the upper position by restricting the swing of the drive side lever 65. For example, the ascending side restricting portion 88 projects inwardly from the rear peripheral wall 84b of the main body case 81. When the movable unit 41 comes to the upper position, for example, the detected portion 70 on the drive side lever 65 side is brought into contact with the movable unit 41 so as to restrict its swing.

  As shown in FIG. 6, the lid 82 includes a left side wall 89 that faces the right side wall 83 on the main body case 81 side, and an outer peripheral frame 90 that protrudes toward the main body case 81 along the outer periphery of the left side wall 89. Are integrally attached to the main body case 81 so as to be substantially closed from the left side.

  In the left side wall 89 of the lid 82, for example, a notch-like drive shaft insertion port 91 and a left end side of the interlocking shaft 71 on the driven lever 66 side are rotatably held, for example, an outwardly recessed bearing portion 74. And the fitting guide part 92 which the protrusion part 77 by the side of the to-be-driven side 66 fits from the inner side is provided in the outer peripheral side of this bearing part 74.

  The drive control of the upper movable effect means 24 having the above configuration will be briefly described. At the normal time, the movable unit 41 is held at the upper position shown in FIGS. 8 (a) and 9 (a). At this time, as shown in FIG. 9A, the driven lever 66 is substantially upward, the driving lever 65 is substantially forward, and the angles formed by the driven side connecting shaft 72, the driving side connecting shaft 69, and the driving shaft 61a are as follows. The angle formed by the support shaft 46, the driven side connecting shaft 72, and the driving side connecting shaft 69 is approximately 90 degrees.

  Here, the driven lever 66 is subjected to a force to swing backward due to the weight of the movable unit 41, but the angle formed by the driven side connecting shaft 72, the driving side connecting shaft 69, and the driving shaft 61a. At 180 degrees, the driven side connecting shaft 72, which is the operating point of the driven side lever 66, is located on the extension line of the driving side lever 65, and the support shaft 46, the driven side connecting shaft 72, and the driving side connecting shaft. Since the angle formed by 69 is approximately 90 degrees and the force from the driven lever 66 side acts on the driving lever 65 in the longitudinal direction, the driving lever 65 is driven by the rotational force of the driven lever 66. It cannot be rotated around the shaft 61a, and the driven lever 66 is prevented from rotating. Therefore, for example, it is possible to reliably prevent the descent from the upper position due to the weight of the movable unit 41 without separately providing a holding means for holding the movable unit 41 at the upper position.

  When an operation command for the movable unit 41 is output from the main control means to the drive control means of the upper movable effect means 24, the drive control means starts drive control of the rotation drive means 61 according to a predetermined operation pattern. As a result, the rotation driving means 61 first operates in the direction in which the movable unit 41 is lowered, that is, the direction in which the driving side lever 65 is swung downward. The driving side connecting shaft 69 that is the operating point of the driving side lever 65 is Since it is not on the extension line of the driven lever 66, the driving in the descending direction is started smoothly without being prevented from rotating.

  Then, by driving in this downward direction, the driven lever 66 swings backward, whereby the angle formed by the support shaft 46, the driven side connecting shaft 72, and the driving side connecting shaft 69 gradually increases from approximately 90 degrees. Although the angle increases, the angle does not reach 180 degrees even when the movable unit 41 reaches the lower position (FIG. 9B). That is, even when the movable unit 41 is in the lower position, the driving side connecting shaft 69 that is the point of action of the driving side lever 65 is not on the extension line of the driven side lever 66, so Even when turning in the ascending direction, the rotation of the driving lever 65 is not prevented, and a smooth driving operation can be maintained.

  When the movable unit 41 reaches the lower position, as shown in FIG. 9B, the driven lever 66 comes into contact with the lowering-side restricting portion 87 and further swinging is restricted. Even when an excessive external force is applied to the unit 41, for example, the driven-side connecting shaft 72 on the driven-side lever 66 side exceeds the straight line connecting the support shaft 46 and the driving shaft 61a and reaches below it. Therefore, a situation in which the movable unit 41 cannot be returned to the upper position by the rotation driving means 61 can be surely prevented.

  When the movable unit 41 is driven in the upward direction as indicated by an arrow in FIG. 9B and the detected portion 70 on the drive lever 65 side is detected by the position detecting means 63, the movable unit 41 reaches the upper position. At that time, the rotation driving means 61 stops and the movable unit 41 is held in that state again.

  As described above, the upper movable effect means 24 mounted on the pachinko machine of the present embodiment has the interlocking means 62 for interlocking the rotation operation of the drive shaft 61a and the rotation operation around the support shaft 46 of the movable unit 41. A drive side lever 65 connected to the drive shaft 61a in the rotation direction and substantially orthogonal to the drive shaft 61a, a driven side lever 66 connected to the support shaft 46 in the rotation direction and substantially orthogonal to the support shaft 46, and a drive side lever 65, the driving side connecting shaft 69 on the tip end side and the driven side connecting shaft 72 on the tip end side of the driven lever 66 are connected to each other in a rotatable manner, and the movable unit 41 comes to the upper position. Since the angle formed by the driven side connecting shaft 72, the driving side connecting shaft 69, and the driving shaft 61a is approximately 180 degrees, the driven unit is in the upper position in the driven state. The driven side connecting shaft 72, which is the operating point of the lever 66, is positioned on the extension line of the driving side lever 65, and the driving side lever 65 is driven by the rotational force of the driven side lever 66 due to the weight of the movable unit 41. The rotation of the driven lever 66 is prevented. Therefore, it is possible to reliably hold the movable unit 41 that can swing in the vertical direction at the upper position thereof and reliably prevent the descent due to its own weight or the like.

  Further, when the movable unit 41 comes to the upper position, the angle formed by the support shaft 46, the driven side connecting shaft 72, and the driving side connecting shaft 69 is approximately 90 degrees. The rotational force of the driven lever 66 when the unit 41 is about to descend due to its own weight or the like can be accurately applied along the longitudinal direction of the driving lever 65 from the driven side connecting shaft 72 that is the point of action. There is an advantage that the lowering due to the weight of the movable unit 41 can be more reliably prevented.

  Further, since the movable unit 41 swings from the upper position to the lower position, the angle formed by the support shaft 46, the driven side connecting shaft 72, and the driving side connecting shaft 69 does not reach 180 degrees. When the movable unit 41 is in the lower position, the drive side connecting shaft 69 that is the operating point of the drive side lever 65 does not come on the extension line of the driven side lever 66, and therefore the movable unit 41 is moved upward from the lower position. Therefore, the drive side lever 65 is not prevented from rotating, and a smooth drive operation can be maintained.

  Further, a lowering side restricting portion 87 for restricting the swing of the movable unit 41 at the lower position is provided, and the lowering side restricting portion 87 is configured to restrict the swinging by bringing the driven lever 66 into contact. Therefore, for example, even when an excessive external force is applied to the movable unit 41 in the descending direction, the driven side connecting shaft 72 on the driven side lever 66 side connects the support shaft 46 and the driving shaft 61a. Therefore, it is possible to reliably prevent a situation in which the movable unit 41 cannot be returned to the upper position depending on the driving of the rotation driving means 61.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to these embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, the configuration of the present invention is effective even when the movable body 41 is not its own weight or is urged downward by some urging means in addition to its own weight.

  In the embodiment, a pachinko machine has been exemplified. However, other ball game machines such as an arrangement ball machine and a sparrow ball game machine as well as various game machines other than a ball game machine such as a slot machine can be similarly implemented. Needless to say.
