FIG. 8 is an exploded perspective view showing the sensor unit, FIG. 9 is a perspective view of the driving means, and FIG. 10 is a front view of the pachinko machine.
[0007]
First, the outline of the pachinko machine P will be described. As shown in FIG. 10, 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, 6... In three columns × three rows at a portion facing the player at the same time, and is added to each of the upper, middle and lower rows and diagonal lines. Five hit lines 7, 7... Are set. The pachinko machine P receives the winning at the start winning opening 3 and changes the symbol 6 of the symbol variation display device 2 in the column direction. When the variation stops, the symbol 6 on the hit line 7 is, for example, “7. , 7, 7 ”or“ ☆, ☆, ☆ ”or the like, the variable winning device 4 is operated under a predetermined condition.
[0008]
Next, the symbol variation display device 2 will be described. The symbol variation display device 2 includes a mounting base 8 positioned on the front side of the game board 1, a symbol variation unit 9 having a symbol display function for one row, and a box-like back side in which three symbol variation units 9 are stored and installed. Case 10. The mounting base 8 is attached to the game board 1 with screws or the like, and has a rectangular display window 5 in which a transparent cover 11 is fitted. In addition, the transparent cover 11 may be formed in a convex lens shape so that the pattern 6 is enlarged and displayed.
[0009]
The symbol changing unit 9 includes a rectangular metal base plate 12, a belt-like and endless symbol display tape 13A, pulleys 14a to 14c and a tension roller 14d for passing the symbol display tape 13A, and a symbol display tape 13A. The driving unit 16 is configured to rotate around, a sensor unit 17 that detects the position of the symbol display tape 13A, and an illumination device 18 that illuminates the symbol display tape 13A.
[0010]
The symbol display tape 13A is formed of a milky white and translucent belt-like translucent film 19 in an endless manner, and on the surface of the translucent film 19, for example, “◯, Δ, □, ☆,. It is made by printing designs 6, 6. Shading belt portions 20a and 20b that are darkly colored over the entire periphery are formed on both side edges of the symbol display tape 13A, and the symbol points 21 are transparent at substantially the same pitch on the shading belt portion 20a on the base plate 12 side. Is formed. One transparent start point 22 is formed on the light shielding belt portion 20b on the other side edge. The symbol display tape 13A is stretched over the pulleys 14a to 14c and the tension roller 14d, and a space between the pulley 14b and the pulley 14c serves as a display area facing the player and faces the display window 5 of the mounting base 8. .
[0011]
Each of the pulleys 14a to 14c and the tension roller 14d has a shape in which a flange 24 for guiding the symbol display tape 13A is provided at the tip of a cylindrical body 23, and is entirely made of a hard synthetic resin. A plurality of lightening holes 25 are provided at equal pitches in the body portion 23 to reduce weight. The pulleys 14a to 14c are disposed at the respective corner portions of the base plate 12, and are rotatable around the rotation shafts 26a to 26c with the flange 15 as shown in FIG. The rotary shafts 26a to 26c are fixed to the base plate 12 with screws, and the pulleys 14a to 14c supported by the rotary shafts 26a to 26c rotate at fixed positions on the base plate 12.
[0012]
On the other hand, the tension roller 14d is rotatably supported by a rotating shaft 26d with a flange 28 at the tip of an arm 27 that is pivotally mounted on the base plate 12 so that the tension roller 14d is rotatably supported by the arm 27. Can rock together. A spring 29, which is a biasing means, is connected to the other end of the arm 27, and the tension roller 14d is biased toward the symbol display tape 13A by the elasticity of the spring 29.
[0013]
A square through hole 30 is formed in the base plate 12 so as to correspond to the swing range of the tension roller 14d. Then, the tension roller 14 d side of the arm 27 is swung in the through hole 30 of the base plate 12. By doing so, the tension roller 14d can be set to the same height level as the other pulleys 14a to 14c. Of course, the through hole 30 of the base plate 12 is not essential, but if the through hole 30 is not provided, the following problems occur. That is, if the through hole 30 is not provided, the arm 27 protrudes completely from the upper surface of the base plate 12, so that the attachment position of the tension roller 14d is increased. If so, the other pulleys 14a to 14c need to be set at high positions, and the bulk of the symbol variation unit 9 (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 display tape 13A so that the volume of the symbol variation unit 9 falls within a specified range. That is, the visibility of the display is sacrificed.
[0014]
The flange 15 integrated with the rotary shafts 26a to 26c has a fan shape in which a circle is divided into almost ¼, but the ¾ portion of the circle is not in contact with the symbol display tape 13A. Therefore, by cutting away the unnecessary portion, the material cost can be reduced and the weight can be reduced. Moreover, since the flange 15 and the flange 28 are separated from the pulleys 14a to 14c and the tension roller 14d as in the embodiment, the symbol display tape 13A can be attached and detached very easily. For example, the other pulleys 14a and 14b and the tension roller 14d may be assembled to the base plate 12 side while leaving the pulley 14c, and after the design display tape 13A is passed over in this state, the pulley 14c may be attached to the rotating shaft 26c. is there.
[0015]
The driving means 16 includes a driving roller 31 that contacts the surface of the symbol display tape 13A, a stepping motor 32 that rotates the driving roller 31, and a pressure roller 33 that presses the symbol display tape 13A against the driving roller 31. As shown in FIG. 9, they are installed on a single small board 34, and are attached to the base plate 12 by screwing the small board 34 to the base plate 12. The small substrate 34 has rubber washers 35 mounted on both front and back surfaces. The rubber washer 35 exhibits an anti-seismic effect that absorbs vibration caused by driving of the stepping motor 32 and an anti-loosening effect.
[0016]
The drive roller 31 is directly connected to the drive shaft 32a of the stepping motor 32, and a cover layer 36 is provided on the outer periphery of the hard body 31a with a material having a slight cushioning property and weak viscosity. The stepping motor 32 is located on the rear edge side of the small substrate 34, and the tail portion is dropped into a semicircular cutout portion 37 provided on the small substrate 34 so as not to be bulky in the height direction.
[0017]
The pressure roller 33 is disposed inside the symbol display tape 13A, and is opposed to the drive roller 31 via the symbol display tape 13A. The pressure roller 33 is rotatably supported at the tip of a roller arm 56 that is pivotally mounted on the small substrate 34. The other end of the roller arm 56 is pulled by the spring 38 and biases the pressure roller 33 toward the drive roller 31. As described above, the symbol display tape 13 </ b> A is interposed between the pressure roller 33 and the drive roller 31, so that the symbol display tape 13 </ b> A is pressed against the peripheral surface of the drive roller 31 by the pressure roller 33. Note that the pressure roller 33 also has a configuration in which a plurality of lightening holes 25 are provided in the hard body portion 33a at an equal pitch, like the pulleys 14a to 14c.
[0018]
The sensor unit 17 includes an optical start sensor S1 and a symbol sensor S2, which are a combination of a light emitting element 39 and a light receiving element 40. As shown in FIG. 8, the start sensor S1 is fixed to the tips of two upper and lower support frames 42 extending long from the sensor substrate 41, and the design sensor S2 is fixed to the sensor substrate 41. Corresponding to the start point 22 of the symbol display tape 13A, the symbol sensor S2 corresponds to the symbol point 21 of the symbol display tape 13A. The upper support frame 42 that supports the start sensor S1 is integrally formed with a shading plate 43 for light shielding.
[0019]
The game control board (not shown) for controlling the symbol variation display device 2 is set so that the symbol 6 is detected by the symbol sensor S2 based on the information after the start point 22 is detected by the start sensor S1. Yes. The stepping motor 32 is controlled by combining signals from the start sensor S1 and the symbol sensor S2. Instead of the optical sensor, the position of the symbol display tape 13A may be detected by other means, such as recording and detecting information on the symbol 6 on the side edge of the symbol display tape 13A. Further, the control of the stepping motor 32 is not necessarily required to combine the signals of the start sensor S1 and the symbol sensor S2, and a system controlled by one sensor may be adopted. As a specific example for this purpose, an arbitrary one of the design points 21 is defined as a reference point, a transparent start point is placed adjacent to the design point 21 of the reference point, and a continuous signal of the design point 21 and the start point is used. There is a method for determining the reference point.
[0020]
The sensor unit 17 is attached to the base plate 12 which is a fixed mounting portion so as to be movable in the circumferential direction of the symbol display tape 13A. That is, as shown in FIG. 8, the sensor unit 17 has three screw holes A22, A22, A22 provided in the sensor substrate 41 aligned with the three round holes 44, 44, 44 formed in the base plate 12. The sensor board 41 has screw holes B21, B21, B21 and C20, C20, C20 in addition to the screw 45, 45, 45. The attachment position on the base plate 12 can be changed in three ways by appropriately selecting the holes A22, B21, and C20. By adopting such a configuration, it is possible to deal with symbol display tapes having different numbers of frames with one type of symbol variation unit 9. This point will be described in detail with reference to FIG.
[0021]
FIG. 6 shows a schematic sectional view of the symbol variation display device 2 and development views of three types of symbol display tapes 13A, 13B, and 13C. The symbol display tape 13A on the right side of the figure is set to 22 frames for symbol 6, the symbol display tape 13B at the center is set to 21 frames, and the symbol display tape 13C on the left side is set to 20 frames. Minute design points 21 are formed. Each of the symbol display tapes 13A, 13B, and 13C includes two types of symbols 6 of large and small, and the center of the symbol point 21 and the center of the symbol 6 are in one-to-one correspondence. Each of the symbol display tapes 13A, 13B, and 13C is set to an approximate length, and is different in length by an adjustment for making the symbol points 21 have an equal pitch. This difference in length can be absorbed by the swinging of the tension roller 14d. Since the symbol display tapes 13A, 13B, and 13C must be matched with the symbol 6 on the hit line 7 of the display window 5 in the stopped state, it is necessary to always stop the symbol point 21 on the center hit line 7. Therefore, if the position of the symbol sensor S2 is set away from the center hit line 7 by a distance of (symbol point pitch × 5), the symbol point 21 that is five points away from that, that is, symbol 6 is the center hit. Stop exactly on line 7.
[0022]
The problem here is that the symbol display tapes 13A, 13B, and 13C differ in the number of frames of the symbol 6, so the pitch of the symbol point 21 is also different, and the distance for five pitches as shown in FIG. 6 is not constant. It is. Therefore, if the sensor unit 17 is fixed in accordance with the symbol display tape 13A for 22 frames, the symbol 6 stopped when the other symbol display tapes 13B and 13C are used and the hit line 7 of the display window 5 The position will be displaced. In this case, it is necessary to recreate the symbol variation unit 9 for each symbol display tape, and much cost and time must be spent.
[0023]
On the other hand, if the sensor unit 17 can be moved in the circumferential direction of the symbol display tape from the beginning, the adjustment by increasing or decreasing the number of frames can be accommodated by the movement of the sensor unit 17. Specifically, if the screw 45 that holds the sensor substrate 41 is removed and the adjacent screw holes B21, B21, B21 are aligned with the round hole 44 of the base plate 12, the symbol sensor S2 at the position of the symbol A in FIG. Is shifted to the position of the same symbol B and corresponds to the symbol display tape 13B for 21 frames. Similarly, if the screw holes C20, C20, C20 are aligned with the round holes 44 of the base plate 12, the position of the symbol sensor S2 is as shown in FIG. By shifting to the position of the middle code C, it is possible to correspond to the symbol display belt 13C for 20 frames. Therefore, one type of symbol variation unit 9 can cope.
[0024]
Various other means for making the sensor unit 17 movable are conceivable. For example, the number of round holes in the base plate 12 and screw holes in the sensor substrate 41 may be reversed. Alternatively, the round hole may be formed into a long hole shape, or the sensor substrate 41 may be slid by fitting the sensor substrate 41 to the rail frame. In this case, a scale that clearly indicates the stop position of the sensor substrate 41 may be displayed on the base plate 12. Further, it is not always necessary to make the entire sensor unit 17 movable, and it is sufficient that at least the symbol sensor S2 that detects the symbol point 21 is movable.
[0025]
As shown in FIG. 3, the illuminating device 18 includes a printed circuit board 18a, fluorescent lamps 18b and 18b which are rod-shaped light emitters, and a large number of light emitting diodes 18c, 18c. The printed circuit board 18a is a rectangle having a size that substantially covers the display area of the symbol display tapes 13A to 13C. As shown in FIGS. 2 and 5, the rectangular opening formed in the base plate 12 of the symbol variation unit 9 is provided. 46 is installed in the area surrounded by the symbol display tapes 13A to 13C. The opening 46 has a convex notch 47 on an extension of one side on the rear side, and the upper and lower edges of the printed board 18a are fitted into the notch 47 and positioned. The fluorescent lamps 18b and 18b have a linear bar shape with a length sufficient to straddle all the symbol display tapes 13A to 13C, and both ends are supported by sockets 18d fixed to the printed circuit board 18a. Further, two fluorescent lamps 18b and 18b are arranged side by side, and the distance between both fluorescent lamps 18b and 18b is substantially equal to one pitch of the symbol point 21.
[0026]
The light emitting diode 18c is a set of six pieces, and nine sets thereof are attached. Each set of the light-emitting diodes 18c is arranged in three columns and three rows so as to correspond to the symbol 6 in the display area, and three sets of the light-emitting diodes 18c corresponding to the symbol 6 in the central row are the two fluorescent lamps. Located between 18b and 18b. Therefore, the fluorescent lamps 18b and 18b function to partition the rows of the light emitting diodes 18c. On the other hand, the surface of the printed circuit board 18a has a reflective structure to which a solder plating 18e is applied. The solder plating 18e is provided in three rows corresponding to each row of the light emitting diodes 18c, and an appropriate gap 48 is formed between adjacent ones. Therefore, when the light-emitting diode 18c is turned on, the light is reflected on the solder plating 18e to illuminate the symbol display tapes 13A to 13C, and the illumination between the symbol display tapes 13A to 13C is extreme due to the gap 48 between the solder platings 18e. Therefore, the light shielding belt portions 20a and 20b on both edges are difficult to see. The above-described solder plating 18e is the most reasonable means for making the surface of the printed circuit board 18a a reflective structure. That is, since the copper foil is attached to the front and back surfaces of the core material on the double-sided type printed circuit board, the solder plating 18e can be easily formed on the surface of the copper foil on the front side using an existing automatic solder bath. Of course, any means may be used as long as the light reflection effect can be obtained, for example, an aluminum foil is attached to a single-sided type printed board, for example, to make the surface of the printed board a reflective structure.
[0027]
Further, as shown in FIG. 5, the base plate 12 is provided with a free hole 49 corresponding to the solder portion of the wiring board in addition to the through hole 30 and the opening 46 described above. The free hole 49 is configured to allow the wiring board to be brought into close contact with the base plate 12 by facing a portion raised by soldering of the wiring board. Therefore, it is not necessary to place the wiring board so as to float on the base plate 12 as in the prior art, which is extremely effective in reducing the thickness of the symbol variation unit 9.
[0028]
Thus, the symbol variation unit 9 corresponds to the symbol 6 for one row, and the three symbol variation units 9 are connected by the screw shaft 51 via the spacer cylinder 50, and this is connected to the back case. 10 is incorporated.
[0029]
In this embodiment, all the components such as the pressure roller 33, the driving roller 31, and the stepping motor 32 are set so as to be within the height range of the pulleys 14a to 14c and the tension roller 14d. By doing so, even when three symbol variation units 9 are arranged side by side as described above, the interval between the symbols 6 adjacent to each other can be minimized. There is an effect that the display balance is very good without spreading unnecessarily.
[0030]
2 and 5, reference numeral 51 denotes a wiring board attached to the base plate 12, reference numeral 52 denotes a connector for external connection attached to the wiring board 51, and reference numeral 53 denotes a sensor in FIGS. A connection connector attached to the substrate 41, reference numeral 54 in FIG. 2 is a connector attached to the wiring board 51 for connection to the connector 53 of the sensor substrate 41. Since the position of the sensor board 41 changes on the base plate 12 as described above, the connector 53 and the connector 54 of the wiring board 51 are connected by a lead wire 55 having a space.
[0031]
Next, the operation of the symbol variation display device 2 of the present invention will be described. First, when a pachinko ball wins the start winning opening 3 in FIG. 6, the stepping motors 32 of the three symbol variation units 9 are started and the drive roller 31 is rotated. Since the surface of the driving roller 31 is covered with the cover layer 36 having a weak viscosity as described above, the friction coefficient is high, and the driving roller 31 is pressed by the pressure roller 33 when the symbol display tapes 13A to 13C are pressed. Therefore, the symbol display tapes 13 </ b> A to 13 </ b> C circulate by the frictional force generated between them and the drive roller 31. Then, the stepping motors 32 are stopped in a predetermined order or all at once, and the combination of symbols 6 on the hit line 7 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. In the symbol variation display device 2 of the embodiment, even if the length of the symbol display tapes 13A to 13C slightly changes due to temperature or long-term use, the tension roller 14d is biased by the spring 29 to the symbol display tapes 13A to 13A. Since it is pressed against 13C, an appropriate tension is always applied to the symbol display tapes 13A to 13C. Therefore, the symbol display tapes 13A to 13C are not loosened and cannot be removed.
[0032]
Thus, the lighting device 18 of the symbol variation display device 2 is set to be controlled by the game control base of the pachinko machine P, and the fluorescent lamp 18b serves as a main light that illuminates the display area from the inside. The light emitting diode 18c is used as a sub-light that changes according to the game state. For example, in a state where two symbols 6 are aligned on one hit line 7 (so-called reach state), only the corresponding light emitting diode 18c blinks on the hit line 7 to appeal, In this case, the sub-light is used for the effect of flashing all the light emitting diodes 18c. Since the fluorescent lamp 18c is arranged at the center of the display area as in the embodiment, the center is bright and the amount of light naturally decreases slightly up and down. It has a visual effect that looks like Further, if a fluorescent lamp is used as the light emitter, the heat effect on the symbol display tapes 13A to 13C is small because it is bright and generates a small amount of heat. Further, the flashing is performed by controlling the inverter for the fluorescent lamp power supply. There are advantages such as being able to
[0033]
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, although two linear lamps are used as the fluorescent lamp 18c in the embodiment, a U-shaped fluorescent lamp in which the two lamps are connected at one end, or an oval shape or a waveform is used. Fluorescent lamps may be used. When a U-shaped or oval fluorescent lamp is used, there is an advantage that wiring can be easily performed because the electrical connection portions can be concentrated in one place.
[0034]
In addition, the symbol 6 of the symbol display tape 13A includes all figures such as letters, numbers and pictures. In the embodiment, the arm length of the tension roller 14d is fixed, but a plurality of (for example, three) shaft holes are formed in the arm 27, and the arm length can be changed by selecting one of the shaft holes. It may be. By doing so, the maximum distance between the swing center of the arm 27 and the outer periphery of the tension roller 14d can be increased or decreased in several steps (for example, three steps), so that it can be widely applied to the symbol display tape 13A having different lengths. Can do. Similarly, in order to achieve the purpose of increasing / decreasing the maximum distance between the swing center of the arm 27 and the outer periphery of the tension roller 14d, the arm 27 is telescopic, and the distance is increased or decreased, or arms having different arm lengths are used. A plurality of types 27 are prepared and selected according to the size of the symbol display tape 13A, or a plurality of tension rollers 14d having different diameters are prepared and selected according to the size of the symbol display tape 13A. It may be.
[0035]
In the embodiment, three symbol variation units 9 are arranged in the back case 10, but the number is arbitrary. If there is at least one game, it is possible to play a game of symbol variation. In the embodiment, the three symbol display tapes 13A to 13C are arranged side by side. However, the symbol display tapes 13A to 13C may be arranged vertically and arranged. Also, the number of pulleys may be more or less than four. The motor for rotating the driving roller 31 may be any motor as long as it can be electrically controlled for rotation. Furthermore, although the pachinko machine P is illustrated as the gaming machine, it can be widely applied to all gaming machines.
[0036]
Therefore, the above-described symbol variation display device includes the following technical idea in addition to the claims 1 of the claims. That is, first, “a component for a gaming machine in which a light emitter (corresponding to the fluorescent lamp 18b and the light emitting diode 18c in the embodiment corresponds to the embodiment) is installed on the surface of the printed circuit board and the surface of the printed circuit board has a reflective structure Lighting equipment. " This lighting device, for example, can be easily solder-plated on the copper foil surface on the front side of a double-sided type printed circuit board using an automatic solder bath, so the waste of the prior art that attached the reflector separately is eliminated. It can be omitted, and the parts cost and assembly time can be greatly reduced.
[0037]
Secondly, “A symbol display tape that displays a plurality of symbols on a strip-like endless film and that has a symbol point corresponding to each symbol, a plurality of pulleys that span the symbol display tape, and a symbol display A driving means for driving the tape to rotate between pulleys; and a symbol sensor for detecting a symbol point of the symbol display tape. The driving means is controlled by a signal of the symbol sensor to achieve a purpose on the symbol display tape. There is a symbol variation display device for a gaming machine that stops the symbol at a predetermined position, and further allows the symbol sensor to move in a rotating direction of the symbol display tape with respect to a fixed mounting portion.
[0038]
Thirdly, “having a symbol display tape formed by displaying a plurality of symbols on a strip-like endless film, a plurality of pulleys over which the symbol display tape is wound, and a drive means for driving the symbol display tape to circulate. In the symbol variation display device, there is a symbol variation display device for a gaming machine in which a plurality of lightening holes are formed in the pulley to reduce the weight. By adopting such a configuration, the moment of inertia of the pulley can be reduced, so that the symbol display tape can be started quickly and the stop position can be made accurate. Of course, it is needless to say that it is more effective to form a hole in the tension roller or pressure roller.
[0039]
Fourth, "a symbol display tape formed by displaying a plurality of symbols on a band-like and endless translucent film, a plurality of pulleys that span the symbol display tape, and a drive means for driving the symbol display tape to circulate. In the symbol variation display device in which a plurality of symbol display tapes are arranged in a side-by-side state, a fluorescent lamp that illuminates the display region facing the player of the symbol display tape from the inside, and each symbol in the display region A lighting device is configured by a combination of correspondingly provided light emitting diodes, the fluorescent lamp of the lighting device is turned on to illuminate the symbol display tape from the inside, and the light emitting diodes are blinked to produce symbol variation. There is a symbol variation display device in a gaming machine. By adopting such a configuration, it is possible to provide a lighting device having excellent durability by utilizing the characteristics of the fluorescent lamp and the light emitting diode.
[0040]
【The invention's effect】
The symbol variation display device according to the first aspect can adjust the driving roller and the pressure roller and check the operation before completion.
[0041]
Further, the symbol variation display device according to the second aspect has an effect that the repair can be easily performed because the replacement of only the drive part which is likely to fail can be performed in a short time .
