【Example】
Embodiments of the present invention will be described below with reference to a pachinko machine as a gaming machine. 1 is a longitudinal sectional view of the symbol variation display device, FIG. 2 is a perspective view showing one symbol variation unit, FIG. 3 is an enlarged sectional view taken along line YY of FIG. 1, and FIG. 4 is a front view of the pachinko machine. is there.
[0008]
First, the outline of the pachinko machine P will be described. As shown in FIG. 4, in the game area 1 a of the game board 1, the symbol variation display device 2 is installed at the center, and the start winning ports 3, 3. The central symbol variation display device 2 displays a total of nine symbols 6 (numbers) in three columns × three rows in a square display window 5 at a time, and a total of five symbols on each of the upper, middle and lower rows and diagonal lines. A hit line is set. Then, the pachinko machine P receives the winnings at the start winning openings 3, 3,..., The symbol 6 of the symbol variation display device 2 is varied in the column direction, and the symbol 6 on the hit line at the time when the symbol variation stops is displayed. For example, in the case of a predetermined combination such as “7, 7, 7”, the variable winning device 4 is operated under a predetermined condition.
[0009]
Next, the symbol variation display device 2 will be described. The symbol variation display device 2 includes a mounting base 7 positioned on the front side of the game board 1, a symbol variation unit 8 having a symbol display function for one row, and a box-shaped rear side in which three symbol variation units 8 are stored and installed. Case 9. The mounting base 7 is attached to the game board 1 with screws or the like, and has a rectangular display window 5 in which a transparent cover 10 is fitted. In addition, the transparent cover 10 may be formed in a convex lens shape so that the pattern 6 is enlarged and displayed.
[0010]
As shown in FIGS. 1 to 3, the symbol variation unit 8 includes a rectangular base plate 11, a strip-like and endless symbol display tape 12, pulleys 13 a to 13 c and a tension that span the symbol display tape 12. Schematic configuration includes a roller 13d, a driving roller 14 that contacts the surface of the symbol display tape 12, a stepping motor 15 that rotates the driving roller 14, and a pressure roller 16 that presses the symbol display tape 12 against the driving roller 14. Is done.
[0011]
The symbol display tape 12 is formed by forming a translucent belt-like film 12a endlessly and printing a plurality of symbols 6, 6... On the surface of the film 12a. A transparent portion 12b is formed on one side edge of the symbol display tape 12 over the entire circumference, and timing points 12c for controlling the stepping motor 15 are printed on the transparent portion 12b at an equal pitch for each symbol 6. Has been. The symbol 6 on the symbol display tape 12 has such a size that three pieces are arranged in a line in the display window 5.
[0012]
The pulleys 13a to 13c and the tension roller 13d have a shape in which flanges 18 for guiding the symbol display tape 12 are provided at both ends of a cylindrical body portion 17, and are entirely made of a hard synthetic resin. Further, a cover layer 19 made of a material having a slight cushioning property and weak viscosity is provided on the outer periphery of the body portion 17. The pulleys 13a to 13c are disposed at the respective corner portions of the base plate 11, and are rotatable about the rotation shafts 20a to 20c. The rotary shafts 20 a to 20 c are fixed to the base plate 11, and therefore the pulleys 13 a to 13 c supported by the rotary shafts 20 a to 20 c rotate at a fixed position on the base plate 11.
[0013]
On the other hand, the tension roller 13d is rotatably supported by a rotating shaft 20d at the tip of an arm 21 that is pivotally mounted on the base plate 11 so that the tension roller 13d swings together with the arm 21. Can move. The arm 21 is provided with three shaft holes 21a to 21c, and the arm length can be changed by selecting one of the shaft holes 21a to 21c. The maximum distance L (see FIG. 3) to the outer periphery of the tension roller 13d can be increased or decreased in three stages. The other end of the arm 21 is connected to a spring 22 as an urging means, and the elasticity of the spring 22 urges the tension roller 13d toward the symbol display tape 12 side.
[0014]
The base plate 11 is formed with a square through hole 23 so as to correspond to the swing range of the tension roller 13d. The pulley 21 d side of the arm 21 is swung in the through hole 23 of the base plate 11. By doing so, the tension roller 13d can be set to the same level as the other pulleys 13a to 13c. Of course, the through hole 23 of the base plate 11 is not essential, but if the through hole 23 is not provided, the following problems arise. That is, if the through hole 23 is not provided, the arm 21 protrudes completely from the upper surface of the base plate 11, so that the attachment position of the tension roller 13d is increased. If so, the other pulleys 13a to 13c need to be set at high positions, and the bulk of the symbol variation unit 8 (the width of the display window 5) increases accordingly. However, since the size of the symbol variation display device 2 is limited to some extent, it is necessary to reduce the width of the symbol variation tape 8 within a specified range by reducing the width of the symbol display tape 12. That is, the visibility of the display is sacrificed.
[0015]
The drive roller 14 is directly connected to the drive shaft 15a of the stepping motor 15, and the cover layer 19 is made of a material having a slight cushioning property and weak viscosity similar to the pulleys 13a to 13c on the outer periphery of the hard body portion 14a. Is provided. The drive roller 14 is arranged so that a part of the peripheral surface projects inward from the straight line connecting the pulley 13c and the tension roller 13d, and the drive roller 14 comes into contact with the surface of the symbol display tape 12 and the symbol display tape. 12 is slightly bent so that the contact area between the symbol display tape 12 and the driving roller 14 is increased.
[0016]
The pressure roller 16 is disposed inside the symbol display tape 12 and faces the drive roller 14 with the symbol display tape 12 interposed therebetween. The pressure roller 16 is rotatably supported at the tip of a roller arm 24 that is pivotally mounted on the base plate 11. The other end of the roller arm 24 is pulled by a spring 25 and biases the pressure roller 16 toward the drive roller 14. Since the symbol display tape 12 is interposed between the pressure roller 16 and the drive roller 14 as described above, the symbol display tape 12 is pressed against the peripheral surface of the drive roller 14 by the pressure roller 16.
[0017]
In addition, a light emitting element 26 and a light receiving element 27 are opposed to the base plate 11 with the symbol display tape 12 in between. The light emitting element 26 and the light receiving element 27 read the timing point 12c of the symbol display tape 12, and the stepping motor 15 is controlled using the signal. Instead of this optical method, a method of obtaining the control signal of the stepping motor 15 by detecting the position of the symbol display tape 12 by other position detecting means such as using magnetism may be adopted. Although not shown, a lamp is incorporated in the area surrounded by the symbol display tape 12 so as to emit light toward the display window 5, and the symbol 6 of the symbol display tape 12 is illuminated by the lamp. Can rise up brightly.
[0018]
The symbol variation unit 8 described above corresponds to the symbol 6 for one row, and three symbols 6 can be displayed on the display window 5 by arranging three symbols in parallel. In this embodiment, all the components such as the pressure roller 16, the driving roller 14, and the stepping motor 15 are set to be within the height range of the pulleys 13a to 13c and the tension roller 13d. By doing so, even when three symbol variation units 8 are arranged side by side as described above, the interval between the adjacent symbols 6 can be minimized, so that the interval between the symbols 6 and 6 in the horizontal direction is reduced. There is an effect that the display balance is very good without spreading unnecessarily.
[0019]
Next, the operation of the symbol variation display device 2 of the present invention will be described. First, when a pachinko ball wins in the start winning opening 3, 3,..., The stepping motors 15 of the three symbol variation units 8 are started and the driving roller 14 is rotated. Since the surface of the driving roller 14 is covered with the cover layer 19 having a weak viscosity as described above, the friction coefficient is high, and the symbol display tape 12 is in contact with the driving roller 14 in a pressurized state by the pressure roller 16. Therefore, the symbol display tape 12 circulates by the frictional force generated between the driving roller 14 and the symbol display tape 12. Then, the stepping motors 15 are stopped in a predetermined order or all at once, and the combination of symbols 6 on the hit line at that time is determined. As a result of the determination, when the symbol 6 is a predetermined combination, the pachinko machine P is in a big hit state, the variable winning device 4 is operated in a predetermined manner, and a predetermined profit is given to the player.
[0020]
In the symbol variation display device 2 of the embodiment, since the pressure roller 16 is disposed on the back side of the symbol display tape 12, even if the symbol display tape 12 is scratched by rubbing against the pressure roller 16, the symbol variation on the surface 6 is displayed. There is no risk of influence, so there is no problem in operation. Even if the length of the symbol display tape 12 changes slightly due to temperature or long-term use, the tension roller 13d is pressed against the symbol display tape 12 by the bias of the spring 22, so that the symbol display tape 12 is always moderate. Tension is applied. Therefore, the symbol display tape 12 does not loosen and does not come off.
[0021]
Thus, when the symbol display tape 12 is changed to a large size having a large number of frames of the symbol 6, the shaft hole 21a of the tension roller 13d may be changed to either the shaft hole 21b or the shaft hole 21c. Then, as shown in the two-dot chain line in FIG. 1, the arm length is increased and the tension roller 13d protrudes to the outside of the symbol display tape 12, so that the large symbol display tape 12 can be passed over without looseness. In order to further enhance such flexibility, it is more effective to provide a plurality of tension rollers 13d.
[0022]
Although the present invention has been described with reference to the embodiments, it is needless to say that the present invention is not limited to the above embodiments. For example, in the above embodiment, the maximum distance L between the swing center of the arm 21 and the outer periphery of the tension roller 13d is increased or decreased by changing the shaft holes 21a to 21c. The distance L may be increased or decreased. In addition, a plurality of types of arms 21 having different arm lengths are prepared and selected according to the size of the symbol display tape 12, or a plurality of tension rollers 13d having different diameters are prepared to have the size of the symbol display tape 12. You may make it select it collectively.
[0023]
In the above embodiment, three symbol variation units 8 are arranged side by side, but the number is arbitrary. If there is at least one game, it is possible to play a game of symbol variation. Also, the number of pulleys may be more or less than four. Further, the motor 15 that rotates the drive roller 14 may be any one as long as it can be electrically controlled for rotation. Furthermore, although pachinko machines have been exemplified as gaming machines, they can be widely applied to all gaming machines.
[0024]
【The invention's effect】
The symbol variation display device of the present invention does not require any special processing such as holes or irregularities on the symbol display tape, so that the cost can be greatly reduced compared to the conventional one, and the symbol display tape is not cut. Furthermore, it is highly durable for long-term operation, and furthermore, it is easy to print a symbol because the symbol display tape is a simple sheet. Furthermore, since there is no mechanical engagement relationship between the drive roller and the symbol display tape, there are many excellent effects such that it is technically easy to rotate the symbol display tape at high speed.
