It is.
[0002]
[Prior art]
In this type of gaming machine represented by a pachinko machine or a slot machine, a rotating drum type variable symbol display device, a rotating belt type variable symbol display device, or a liquid crystal type is generally used as an entity display unit for a symbol combination game. The variable symbol display device is used. Of these, the rotary drum-type variable symbol display device requires a large motor when the symbol drum is to be increased in size (larger diameter) in order to cope with an increase in the number of symbols and an increase in size. In addition, the front and rear size of the device itself is large, and when installed in a gaming machine, it causes a disadvantage that it protrudes greatly to the back side, and there is a problem that it cannot fully respond to the diversification of display contents in the symbol combination game. . Therefore, the above-described rotating belt type variable symbol display device has been adopted as a solution to the problems inherent in the rotary drum type variable symbol display device.
[0003]
For example, FIG. 8 and FIG. 9 show an entity display unit of the rotating belt type symbol variable display device M in the pachinko machine, and among the three symbol display units U accommodated and installed in the accommodating case member 20 in parallel. It is a sectional side view which shows one of these roughly. The symbol display unit U is a support plate of the unit U and is fixed to the set plate 30 as one set plate (fixed support means) 30 also serving as a drive substrate that is positioned and held in the housing case member 20. The rotation drive control mechanism 31 having the driven motor 32 and the three pulleys 33, 34, 35 including the tension adjustment, and an endless state between the outer circumferences of the pulleys 33, 34, 35 in the rotation drive control mechanism 31 A mark-type symbol belt 37 made of a film, an optical detection means 38 for detecting the position of the symbol 71 during the movement of the symbol belt 37, and a display area in the front belt portion 37a of the symbol belt 37. The illuminating means 39 for illuminating the design 71 from the inside is basically constructed and can be handled as a unit by the set plate 30 unit.
[0004]
In the rotating belt type variable symbol display device M incorporating the symbol display unit U, it is easily positioned and set in units of the housing case member 20 with respect to the back side of the game board H of the pachinko machine. In this state, each symbol display unit The front side belt portion 37a of the design belt 37 in U faces the perspective display window 14 of the large decorative part 13 provided on the game board H, and the design 71 arriving at the front side belt portion 37a is visually recognized through the perspective display window 14. Be able to be. When a detection signal (start signal) from the start winning switch in the game board H is input to a control board (not shown) along with the start of the game on the gaming machine, the required variation pattern set by the control board is displayed. On the basis of the driving motor 32 being driven, the design belt 37 is rotationally varied, and after the variation pattern is finished, the predetermined design 71 set in advance is stopped at the stop display position of the front side band portion 37a, whereby the design 71 Are aligned on a display line formed in the fluoroscopic display window 14.
[0005]
[Problems to be solved by the invention]
In such a rotating belt type variable symbol display device M, the display area can be enlarged to some extent without increasing the size in the front-rear direction, compared to the rotary drum type variable symbol display device described above. It is possible to cope with the diversification of the display contents in the symbol combination game by increasing the size of the symbol and increasing the number of symbols. However, as shown in FIG. 9, the driving pulley 33, the driven pulley 34, and the tension pulley 35 are slightly different in diameter and shape, but all contact with the entire width direction of the back surface of the design belt 37. Even if it is formed into a cylindrical shape having a wide rim portion and is molded from a lightweight synthetic resin, there is a limit to reducing the weight.
[0006]
Therefore, the pulleys 33, 34, and 35 have a large inertia, and the load on the drive motor 32 increases when the symbol belt 37 is accelerated and decelerated due to the start / stop of the drive motor 32. It was inherent. Further, the response to the rotational fluctuation of the drive motor 32 is deteriorated, causing malfunction, and inertial slip is likely to occur between the design belt 37 and the pulleys 33, 34, 35, and this slip is caused. Wear on the back surface of the belt 37, generation of scratches, and the like have also been serious problems. Furthermore, as described above, since the drive pulley 33, the driven pulley 34, and the tension pulley 35 are in contact with the entire back surface of the design belt 37, it is pointed out that inconvenience is likely to occur due to dirt, tobacco stains, and the like. The

It is configured. The design belt 37 is stretched between the outer circumferences of the drive pulley 33, the driven pulley 34, the tension pulley 35, and the idle pulley 36 in a stretched state. That is, in each symbol display unit U in the variable symbol display device M of the embodiment, compared with the conventional symbol display unit U shown in FIG. 8, there is a gap between the driving pulley 33 and the driven pulley 34 in the set plate 30. The idle pulley 36 that supports the front belt portion 37a of the design belt 37 from the back side is additionally installed, and the pulleys 33, 34, 35, and 36 are reduced in weight.
[0019]
(Drive pulley)
The drive pulley 33 is a spear type in which a first drive pulley (first half) 49 and a second drive pulley (second half) 50 made of synthetic resin including a rim portion 51 and a spoke portion 52 are opposed to each other. When the pulleys 49, 50 are assembled to the drive shaft 32a of the drive motor 32 with screws 48, the drive motor 32 is accommodated inside the first drive pulley 49. ing. Then, the outer peripheral surfaces 51a and 51a of the rim portions 51 and 51 of the pulleys 49 and 50 respectively support the left side edge (one side edge) and the right side edge (other side edge) of the pattern belt 37 in the width direction. On the other hand, protrusions 53 are formed on the outer peripheral surface 51a of the first drive pulley 49 at every required interval to form a sprocket shape. Therefore, compared with the conventional drive pulley 33 shown in FIG. 8, the intermediate part of the rim part is largely removed, so that at least the material corresponding to this part is reduced and the weight is greatly reduced. Along with this, inertia has been greatly reduced. As a result, the drive pulley 33 is in contact with both side edges of the back surface of the design belt 37 only by the outer peripheral surfaces 51 a and 51 a of the narrow rim parts 51 and 51 provided at both end portions. Most of the back surface except for the rotational movement of the drive pulley 33 in a non-contact state.
[0020]
(Driven pulley)
The driven pulley 34 is rotatably disposed on a rotation support shaft 55 that is horizontally fixed to an upper front portion on the front side of the set plate 30, and is a first driven pulley (first half body) made of synthetic resin located on the left side of the front surface. ) 34A and the first driven pulley (second half) 34A located on the right side of the front and a second driven pulley 34B made of synthetic resin and formed symmetrically, and each driven pulley 34A. , 34B are rotatably supported with respect to the set plate 30 independently. Among these, the first driven pulley 34A is composed of a support cylinder portion 56 fitted on the rotation support shaft 55, and a rim portion 57 formed on both sides of the support cylinder portion 56 via a plurality of spokes 59, The outer peripheral surface 57 a of the rim portion 57 supports the left side edge (one side edge) of the symbol belt 37. The second driven pulley 34B includes a support cylinder portion 56 that is externally fitted to the rotation support shaft 55, and a rim portion 57 that is formed on both sides of the support cylinder portion 56 via a plurality of spokes 59. The outer peripheral surface 57a of the rim portion 57 supports the right edge (other edge) of the symbol belt 37. Further, a flange 58 for integrally preventing the symbol belt 37 from coming off is integrally formed on the outer side surfaces of the rim portions 57 and 57. Therefore, as compared with the conventional driven pulley 34 shown in FIG. 8, the intermediate portion of the rim portion is largely removed, so that at least the material corresponding to this portion is reduced and the weight is considerably reduced. By dividing into two, inertia is also greatly reduced. As a result, the driven pulley 34 is in contact with both end edges of the back surface of the design belt 37 only by the outer peripheral surfaces 57a, 57a of the narrow rim portions 57, 57 provided at both end portions. Most of the back surface except for the rotational movement of the driven pulley 34 in a non-contact state.
[0021]
(Tension pulley)
The tension pulley 35 is rotatably disposed via a rotation support shaft 63 at an upper end portion of an arm 61 that is swingably supported by a swing support shaft 60 that is horizontally fixed behind the front side of the set plate 30. The first tension pulley (first half) 35A made of synthetic resin located on the left side of the front is divided into the second tension pulley 35B made of synthetic resin located on the right side of the front, and each tension pulley 35A, 35B is divided. Is rotatably supported with respect to the arm 61. The first tension pulley 35A includes a support cylinder part 77 fitted on the rotation support shaft 63, and a rim part 79 formed on both sides of the support cylinder part 77 via a plurality of spokes 78. The outer peripheral surface 79 a of the rim portion 79 supports the left side of the back surface of the symbol belt 37. The second tension pulley 35B includes a support cylinder portion 77 fitted on the rotation support shaft 63 and rim portions 79 formed on both sides of the support cylinder portion 77 via a plurality of spokes 78. The outer peripheral surface 79a of the rim portion 79 supports the right side of the back surface of the symbol belt 37. Therefore, as compared with the conventional tension pulley 35 shown in FIG. 8, the weight is reduced and the inertia is reduced by dividing the left and right two parts. The arm 61 is always urged to swing counterclockwise in FIG. 1 by a torsion spring 62, and the tension pulley 35 is pressed against the back surface of the design belt 37 under the urging of the spring 62. The design belt 37 can always be guided while being held in an appropriate stretched state. The tension pulley 35 has a so-called barrel shape as a whole because the outer diameter of the intermediate portion where the first tension pulley 35A and the second tension pulley 35B are adjacent to each other is set to be slightly larger. It is designed to support the spread and prevent disengagement.
[0022]
(Idle pulley)
The idle pulley 36 that is additionally installed between the drive pulley 33 and the driven pulley 34 is horizontally disposed at a substantially central portion on the front side of the set plate 30 and on the rear side of the illumination means 39, as shown in FIGS. A synthetic resin first idle pulley (first half) 36A, which is rotatably disposed on a fixed rotation support shaft 65 and is located on the left side of the front surface, and a first idle pulley 36A which is located on the right side of the front surface, The second idle pulley (second half) 36B made of synthetic resin is formed in a symmetrical shape, and each idle pulley 36A, 36B is rotatably supported with respect to the set plate 30 independently. . Of these, the first idle pulley 36 </ b> A is a support that is externally fitted to the narrow and relatively large rim portion 67 located on the left side (one side) of the cover member 80 of the illumination means 39 and the rotary support shaft 65. A cylindrical portion 66 is connected by a plurality of (e.g., 10) spokes 68, and a first support surface (outer peripheral surface) 67a formed on the outer periphery of the rim portion 67 is a left edge of the front belt portion 37a in the design belt 37. (One side edge) is supported. The second idle pulley 36B is a narrow and relatively large rim portion 67 located on the right side (the other side) of the cover member 80 of the illuminating means 39 and a support cylinder fitted on the rotary support shaft 65. The portion 66 is connected by a plurality of (e.g., 10) spokes 68, and the second support surface (outer peripheral surface) 67b formed on the outer periphery of the rim portion 67 is the right edge of the front belt portion 37a in the design belt 37 ( It supports the other side edge).
[0023]
As shown in FIG. 1, the first idle pulley 36 </ b> A and the second idle pulley 36 </ b> B are configured such that the front edges of the support surfaces 67 a and 67 b of the rim portions 67 and 67 are the outer peripheral surfaces 51 a of the drive pulley 33. And a tangent line S connecting the leading edge of the outer peripheral surface 57a of the driven pulley 34 and a predetermined amount offset forward (right side in FIG. 1). Thereby, as is apparent from the drawing, the front side band portion 37a is a pseudo circle that forms part of a relatively large-diameter pseudo circle that contacts the support surfaces 67a and 67b of the drive pulley 33, the driven pulley 34, and the idle pulley 36. It extends in an arc shape. Therefore, when the symbol variable display device M containing the symbol display unit U is attached to the back side of the game board H, the front side belt portion 37a extending in a pseudo arc shape of the symbol belt 37 is formed in the perspective display window 14. It is set to face while curving to the side.
[0024]
Further, since the front belt portion 37a of the design belt 37 is supported by the drive pulley 33, the driven pulley 34 and the idle pulley 36 only on the left edge and the right edge, the dent deformation of the unsupported back side intermediate portion is caused. Although it is feared, the dent deformation | transformation of an intermediate | middle part is suitably prevented now by extending in the pseudo-arc shape. That is, as is well known, in the belt-like body such as the design belt 37, the intermediate portion in the width direction is easily recessed when the belt is in a straight state, but the recess in the intermediate portion is preferable when the belt is bent or bent. It has the property to be prevented. In the front side band portion 37a using this characteristic, no dent is generated in the intermediate portion, so that inconveniences such as each pattern 71 arriving at the front side band portion 37a appear to be distorted are preferably avoided, and a suitable symbol display is made. obtain. Further, the front side belt portion 37a is supported by the idle pulley 36 at a substantially upper and lower intermediate portion, so that it is possible to suitably prevent occurrence of vibrations such as back and forth and right and left and blurring during rotational movement.
[0025]
(Design belt)
The design belt 37 is formed as an endless belt having extremely high tensile strength and small expansion and contraction by welding both ends in the longitudinal direction of the design display body formed to a required length, and in the rotational drive control mechanism 31. The pulleys 33, 34, 35, and 36 are hooked and set as shown in FIGS. In other words, the pattern belt 37 is maintained in an appropriate stretched state as a whole by the urging force acting on the tension pulley 35, and is substantially half the circumference of each outer peripheral surface 51a, 51a of the drive pulley 33. On the other hand, the front belt portion 37a extending between the drive pulley 33 and the driven pulley 34 is stretched in a pseudo-arc shape curved forward by the idle pulley 36, and the drive pulley 33 and the tension pulley 35 are always received. The rear side belt part 37b extending between the two is extended in a substantially vertical straight line state. Further, on one side edge portion (right side edge) of the design belt 37, a locking hole 70 is formed at every required interval so that each protrusion 53 provided on the driving pulley 33 can be engaged. As the projections 53 are sequentially engaged / separated with the respective locking holes 70 under the rotation, the slippage of the design belt 37 is preferably avoided, and stable and reliable rotational movement of the design belt 37 can be realized. It has become. The design belt 37 can be quickly attached and detached using the posture displacement of the arm 61 that supports the tension pulley 35 (forcibly swinging clockwise in FIG. 1).
[0026]
Specifically, the symbol display body which is the base of the symbol belt 37 is a laminate of two transparent ultra-thin film materials (for example, polyester, thickness 25 to 40 μm) having high tensile strength and small expansion and contraction. Used and formed into a predetermined length and width dimension based on a predetermined printing cutting technique.

[0029]
As described above, the three symbol display units U configured by one set plate 30 unit are accommodated and set in the accommodation chamber 23 of the accommodation case member 20 in parallel as shown in FIG. Thus, the entity variable display device M in the symbol variable display device M constitutes a set of entity display portions including a left column, a middle column, and a right column. Then, each circuit board 40 in each symbol display unit U is connected to the relay board 45 via the relay connector 44, and the relay board 45 is connected to a control board (not shown), thereby the control board. Thus, the drive control of each of the symbol display units U, U, U is made possible.
[0030]
[Effect of the embodiment]
Next, the operation of the symbol variable display device for a symbol combination gaming machine according to the present embodiment configured as described above will be described.
[0031]
(Design variable display device set)
The symbol variable display device M of the embodiment assembled by accommodating the three symbol display units U, U, U configured as described above in parallel in the storage chamber 23 of the storage case member 20 is shown in FIG. The game board H having the display window 14 is assembled and attached to a predetermined position on the back side of the game board H by using screws or appropriate fixing means. Thereby, in each symbol display unit U, as shown in FIG. 1, the pseudo-arc-shaped front side band portion 37 a of the symbol belt 37 is located behind the fluoroscopic display window 14 in the large decorative component 13 installed on the game board H. To be consistent.
[0032]
When the start winning switch detection signal (start signal) by entering the start winning tool 12 is input to the control board with the start of the game on the pachinko machine P, the processing result on the control board Symbol variation control corresponding to the variation pattern set as is executed. That is, in each symbol display unit U, the symbol belt 37 stretched around the drive pulley 33, the driven pulley 34, the tension pulley 35 and the idle pulley 36 is controlled by driving the drive motor 32 in the rotation drive control mechanism 31. , And the position of each symbol 71 is detected based on the detection of the reference mark 72 and the symbol mark 73 by the detection means 38, and the symbol 71 arriving at the front side band portion 37 a is further backside by the illumination means 39. Illuminate from. Then, after completion of the variation control based on the variation pattern set on the control board, the symbol belt 37 stops moving based on the stop control of the rotation drive control mechanism 31 of each symbol display unit U, and the front belt portion 37a The required symbol 71 that has arrived is displayed on the display line L of the fluoroscopic display window 14.
[0033]
Here, in the symbol variable display device M of the embodiment, since the front belt portion 37a of the symbol belt 37 in each of the symbol display units U extends in a pseudo arc shape curved to the front side, it arrives at the front belt portion 37a. Each symbol 71 to be moved comes close to the see-through display window 14 side. Therefore, the visibility of each symbol 71 seen through the perspective display window 14 is improved, and the symbol display effect for a player who is sitting on the front surface of the pachinko machine P and playing a game is preferably improved. Moreover, when compared with the conventional variable symbol display device M (FIG. 8) in which the front side band portion 37a extends linearly, the front side band portion 37a of the present embodiment extending in a pseudo arc shape is more. Since the extension length is long, the display area is enlarged accordingly, and the symbol display effect is further improved.
[0034]
Further, since the front belt portion 37a of the design belt 37 extends in a pseudo arc shape, the front belt portion 37a can be suitably prevented from being deformed in the middle of the front belt portion 37a in the width direction. Inconveniences such as the symbols 71 appearing distorted appear to be distorted are preferably avoided, and a suitable symbol display can be achieved.
[0035]
Further, since the illuminating means 39 faces along the back side of the front side band portion 37a extending in a pseudo arc shape, the design 71 that has arrived at the front side band portion 37a is directly illuminated by each lamp 82. Thus, the entire enlarged display area can be reliably and uniformly illuminated, and the symbol display effect can be improved by increasing the illumination effect.
[0036]
Further, in the rotational drive control mechanism 31 in each symbol display unit U, the drive pulley 33, the driven pulley 34, the tension pulley 35, and the idle pulley 36 are significantly reduced in weight. In addition, the driven pulley 34 and the tension pulley 35 are also added. Since the idle pulley 36 is divided into left and right parts and rotates independently, the pulleys 33, 34, 35, and 36 are greatly reduced in inertia, and the drive motor 32 is activated at the time of acceleration. The start-up and the deceleration at the time of deceleration stop are very light and smooth, the burden on the drive motor 32 is reduced, and the occurrence of malfunctions and the occurrence of abrasion and scratches on the back of the symbol belt 37 are suitably prevented. The additionally installed idle pulley 36 is made as light as possible and is divided into a left and right first idle pulley 36A and a second idle pulley 36B. Therefore, the idle pulley 36 also has inertia. As a result, the load on the drive motor 32 is minimized.
[0037]
Furthermore, the drive pulley 33, the driven pulley 34, and the idle pulley 36 do not contact the back surface of the symbol belt 37 over the entire outer peripheral surface of the wide rim portion, but instead of the outer peripheral surfaces 51a, 51a, 51b of the narrow rim portions 51, 57, 67. 57a and support surfaces 67a and 67b are adapted to be in contact with and support only the left and right edges of the back surface of the design belt 37. Therefore, in addition to preventing wear on the back side of the design belt 37 and preventing formation of scratches, the occurrence of dirt, dirt contamination, etc. due to dust or tobacco dust is suitably reduced. That is, at least one of the drive pulley 33, the driven pulley 34, the tension pulley 35, and the idle pulley 36 has a structure in which a rim portion having a required width is provided at both end portions in the width direction. The one side edge of the symbol belt 37 is rotationally supported by the outer peripheral surface of the portion, and the other side edge of the symbol belt 37 is rotationally supported by the outer peripheral surface of the other rim portion. Demonstrated. However, preferably, with respect to all the pulleys 33, 34, 35, and 36, if a rim portion having a required width is provided at both side end portions in the width direction, the regions excluding both side end portions on the back surface of the design belt 37 are different. The pulleys 33, 34, 35, and 36 are not in contact at all, and further improvement of each effect such as wear prevention, scratch formation prevention, and dirt adhesion prevention is expected.
[0038]
In the variable symbol display device M of the embodiment, the outer peripheral surfaces 51a and 57a of the drive pulley 33 and the driven pulley 34 and the idle pulley are changed by changing the position of the idle pulley 36 relative to the set plate 30 back and forth. Since the outer diameter of the pseudo circle contacting the 36 support surfaces 67a and 67b changes, the curvature of the pseudo arc of the front side band portion 37a can be changed accordingly. For example, if the idle pulley 36 is further offset in the front direction of the set plate 30, the curvature of the pseudo arc of the front side band portion 37 a is further reduced and can be brought closer to the fluoroscopic display window 14 side. .
[0039]
That is, in the symbol variable display device M, the front belt portion 37a of the symbol belt 37 can be a pseudo arc having a curvature larger than the outer diameter of the idle pulley 36 without increasing the front and rear size of the device M.
[0040]
When the symbol variable display device M is used in a slot machine, the set and the weight of the rotary drive control mechanism 31 including the drive motor 32 and the pulleys 33, 34, 35, and 36 are increased. An appropriate fixing support means having higher rigidity than the plate 30, for example, a metal set plate or the like is employed. Furthermore, in the slot machine, since the game board H that is a component of the pachinko machine P is not equipped, the symbol variable display device M is installed in a state of being housed inside the casing of the slot machine. The front side band portion 37a of the design belt 37 in the display unit U faces the transparent display window provided on the front decorative door of the casing.
