Description

  The present invention relates to a gaming machine such as a pachinko machine or a slot machine having a relatively large movable body movable in the vertical direction.

  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. 9 and the like, the holding unit 45 includes a magnet 61 disposed on the movable member 43 side and a magnetic metal member 62 disposed on the fixed member 41 side. For example, the magnet 61 is formed in an H shape in a front view integrally including a pair of suction pieces 63 and a fixed piece 64 that are parallel to each other, and a connection portion 65 that connects the suction pieces 63 and the fixed piece 64 at the center. In the state in which the attracting piece 63 protrudes to the outer peripheral side of the movable member 43, the fixed piece 64 is fitted and fixed to the magnet fixing portion 66 on the movable member 43 side so that it can be attached to and detached from the upper edge side of the movable member 43. It is installed.

  The magnetic metal member 62 is a substantially J-shape in which a plurality of (three here) flat plate portions having different areas are connected at right angles by bending a ferromagnetic metal plate such as stainless steel at a plurality of places (here two places). And is detachably attached to the magnetic metal holding means 67 provided on the fixing member 41 side. The outer surfaces of the three flat plate portions of the magnetic metal member 62 are first to third adsorption surfaces 62a to 62c for the magnet 61, respectively, and the area of the first adsorption surface 62a is the largest, and the third adsorption surface 62c. Is the smallest.

  The magnetic metal holding means 67 is disposed on the fixed member 41 side corresponding to the position of the magnet 61 when the movable body 24 is in the steady position, and includes a holding groove 68 into which the magnetic metal member 62 can be fitted. A holding case 69 and a retaining member 70 made of a screw with a washer or the like that is detachably attached to the holding case 69 so as to hold the magnetic metal member 62 in the holding groove 68 are provided.

  The holding groove 68 includes a first holding groove 68 a that holds the magnetic metal member 62 so that the first attracting surface 62 a faces the magnet 61, and a magnetic metal member 62 that makes the second attracting surface 62 b face the magnet 61. Three types of holding grooves (holding portions) 68a to 68c, which are the second holding groove 68b for holding and the third holding groove 68c for holding the magnetic metal member 62 so that the third attracting surface 62c faces the magnet 61, are combined. When the movable body 24 is in the steady position, any one of the first to third suction surfaces 62a to 62c is attracted to the magnet 61, so that the movable member 43 and the movable body that operates integrally therewith 24 is held in a steady position.

  The drive control of the movable effect means 25 having the above configuration will be briefly described. Normally, the movable body 24 is in a steady position, and the magnet 61 on the movable member 43 side is attracted to any one of the first to third suction surfaces 62a to 62c of the magnetic metal member 62 on the fixed member 41 side. State is maintained.

  When an operation command for the movable body 24 is output from the main control means 72 to the drive control means 71, the drive control means 71 starts drive control of the drive means 44 according to a predetermined operation pattern. As shown in FIG. 11, this operation pattern is preset by data in which the operation direction (down, pause, ascend, etc.) and the corresponding driving speed (for example, time per step) are arranged in a time sequence.

  Here, every operation pattern starts with a lowering operation. In this lowering operation from the steady position, the driving unit 44 is movable against the holding force of the holding unit 45, that is, the adsorption force of the magnet 61 to the magnetic metal member 62. Since it is necessary to drive the member 43, the drive control means 71 operates the drive means 44 at a lower speed than usual (for example, 16 ms per step), for example, for the first predetermined step (for example, 30 steps), thereby After the magnet 61 is separated from the magnetic metal member 62, the speed is increased (for example, 8 ms per step). Thereby, it is possible to drive the movable body 24 more smoothly while suppressing the vibration operation caused by the sudden change in resistance by the holding means 45.

  Further, in this embodiment, since the areas of the first to third adsorption surfaces 62a to 62c of the magnetic metal member 62 are all different, the magnetic metal member 62 is made to be the first to the first metal as shown in FIGS. The holding force by the holding means 45 can be changed depending on which of the third holding grooves 68a to 68c is mounted, that is, which of the first to third suction surfaces 62a to 62c is opposed to the magnet 61. The holding force by the holding means 45 can be easily adjusted so that the descent start operation becomes smoother while securing the holding force.

  When the movable body 24 is raised through lowering, resting, etc., the drive control means 71 operates the driving means 44 to the ascending side by the total number of steps of the lowering operation + the number of steps. This + α corresponds to an error between the theoretical number of steps and the actual number of steps until the detection switch 51 detects the detected portion 50, and the drive control means 71 detects the detection switch during the upward drive. When the detection signal from 51 is received, the drive operation of the drive means 44 is stopped. At this time, the movable body 24 returns to the steady position and is held again at the steady position by the holding means 45.

  As described above, the pachinko machine of the present invention includes the holding means 45 that holds the movable body 24 in a steady position when the driving means 44 is not in operation, and this holding means 45 is a magnet provided on the movable body 24 side. 61 and a magnetic metal member 62 provided on the rear structure 23 side corresponding to the magnet 61, and among the attracting surfaces 62 a to 62 c of the magnetic metal member 62 when the movable body 24 is in a steady position. Since any one of these is configured to be attracted to the magnet 61, the large movable body 24 that can move up and down can be reliably held in a steady position even if some impact or vibration occurs. .

  Further, magnetic metal holding means 67 for detachably holding the magnetic metal member 62 is provided on the rear structure 23 side, and the magnetic metal member 62 has a plurality of types of first to third adsorption surfaces 62a to 62c having different areas. The magnetic metal holding means 67 includes first to third holding grooves 68a to 68c that hold the magnetic metal member 62 with the first to third attracting surfaces 62a to 62c facing the magnet 61 side. Are provided in accordance with the number of first to third suction surfaces 62a to 62c, so that the holding force by the holding means 45 can be increased so that the descent start operation becomes smoother while ensuring a certain holding force. It can be easily adjusted.

  FIG. 12 illustrates a second embodiment of the present invention and shows an example in which the magnetic metal holding means 67 is configured to hold the magnetic metal member 62 rotatably.

  As in the first embodiment, the magnetic metal member 62 of the present embodiment is formed in a substantially J shape in which the first to third suction surfaces 62a to 62c having different areas are connected to each other at right angles. The three suction surfaces 62a to 62c are held rotatably about a rotation shaft 73 provided at an equidistant position. That is, the first to third suction surfaces 62 a to 62 c are arranged in different directions on the circumference around the rotation shaft 73. The rotating shaft 73 is provided on a flat plate extending from the end of the third suction surface 62c, for example.

  With the above configuration, the attracting surface facing the magnet 61 can be changed only by rotating the magnetic metal member 62 around the rotation shaft 73 without attaching or detaching the magnetic metal member 62.

  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, one of the magnet 61 and the magnetic metal member 62 may be provided on the fixed side of the rear structure 23 or the like, and the other may be provided on the movable body 24 or the movable side operating integrally therewith.

  The movable body 24 only needs to be movable in the vertical direction, and is not limited to one that swings around the central axis as in the embodiment, and may be one that slides in the vertical direction, for example.

  The magnetic metal member 62 only needs to have adsorption surfaces with different areas in different directions, and the angle formed by each adsorption surface is arbitrary. For example, a plurality of adsorption surfaces are connected at an angle shallower than 90 degrees. Also good.

  Moreover, as a structure which can change the attraction | suction area with respect to the magnet 61 of an attraction | suction surface, in addition to what selects one of the some attraction | suction surfaces 62a-62c like embodiment, for example, one attraction surface was provided.
