The present invention relates to a rotary symbol display device for a gaming machine provided with position detecting means for performing the above.
[0002]
[Prior art]
In a pachinko machine that is a representative example of a gaming machine, a combination prize that is a right related to a special gaming state is developed by developing a symbol combination game based on a symbol variation control condition including start and stop that occurs during a game. A rotary symbol display device called a drum type or a belt type capable of satisfying and displaying conditions is provided. For example, a drum-type symbol display device is provided with a flat pulley-shaped symbol drum displaying various symbols as a symbol display body, and a driving means for rotating and stopping the symbol drum on a wiring board. A plurality of units (usually three in the left column, middle column, and right column) are set in parallel in a drum case (storage case).
[0003]
Further, an index (position detection body) serving as a position index of the design drum is erected inwardly on the inner peripheral surface of the design drum, and a detection sensor for detecting the index on the wiring board ( Position detecting means) is disposed and fixed. Then, when the detection sensor detects an index that rotates integrally with the symbol drum, a reference position of the symbol drum is recognized, and a predetermined amount is controlled by controlling the amount of rotation of the symbol drum from the reference position. It is configured so that symbols can be stopped and displayed.
[0004]
The wiring board is provided with illuminating means including a light emitting body (such as an LED) that emits light and a reflector that receives light from the light emitting body and reflects the surface thereof, so that the design of the design drum is rear surfaced. Configured to illuminate from the side. As a means for fixing the reflector to the wiring board, after positioning the reflector by inserting a plurality of positioning bosses projecting at predetermined positions of the reflector into holes formed corresponding to the wiring board, both the reflectors are positioned. A configuration in which the member is fixed with screws is employed.
[0005]
[Problems to be solved by the invention]
By the way, it is preferable that the index and the detection sensor are as close as possible to prevent an error in detecting the reference position. However, the index may be formed at a position separated from the wiring board. In this case, a configuration is adopted in which an attachment member is provided on the wiring board and a detection sensor is attached to the attachment member so as to be close to the index. . In this case, the detection sensor needs to be accurately positioned with respect to the index, and a means using a boss and a hole is employed as a positioning means for the mounting member with respect to the wiring board. However, a plurality of bosses and holes are required for positioning, and the disadvantage of increasing the cost is pointed out.

The second openings 43, 43, 43 are formed at locations corresponding to a boundary between an upper reflective surface 42a and a central reflective surface 42b, which will be described later, and a boundary between the central reflective surface 42b and the lower reflective surface 42c, respectively. Each of the second openings 43 communicates with the upper reflecting surface 42a, the central reflecting surface 42b, and the lower reflecting surface 42c. Further, a predetermined passage 45 is formed by separating the fixing member 44 and the stepping motor 38 by a predetermined distance (see FIG. 5 or FIG. 6), and the design drum 34 is driven by driving the stepping motor 38. When the is rotated, the index 46 passes through the passage 45.
[0034]
As shown in FIG. 1 or FIG. 9, the reflector 42 forms an outer peripheral surface of an arc-shaped member, and communicates with the first opening 32 f and the second openings 43 to emit light from the LEDs 41 a. Main reflection surfaces 42a, 42b, 42c that are reflected on the symbols of the symbol drum 34 that pass through the visible indicator 15 and inner surfaces of the reflector 42 as the arcuate member are formed and directed toward the visible indicator 15. The auxiliary reflecting surfaces 42d, 42e, 42f, and 42g that protrude and reflect the light from the LED 41a toward the inside of the design drum 34 are configured.
[0035]
As shown in FIG. 1, FIG. 5 or FIG. 9, the main reflecting surface of the reflector 42 is formed in parallel with the axial direction of the design drum 34, and the outer peripheral surface is sequentially inclined in the circumferential direction at a required interval. The upper reflection surface 42a, the central reflection surface 42b, and the lower reflection surface 42c. The upper reflection surface 42a, the central reflection surface 42b, and the lower reflection surface 42c correspond to the upper, middle, and lower stages of the symbol stop line T in the visible display unit 15, respectively. The left and right width dimensions of the reflecting surfaces 42a, 42b, and 42c are set smaller than the width dimension of the symbol drum 34.
[0036]
The auxiliary reflecting surface is formed at the upper edge of the upper reflecting surface 42a as shown in FIG. 1, FIG. 6, or FIG. 9, and spreads in the width direction of the symbol drum 34 to the visible display portion 15. The upper reflection surface 42d that protrudes outward (front side) as it comes closer and the lower edge of the lower reflection surface 42c are formed so as to expand in the width direction of the design drum 34 and as it approaches the visible display portion 15. The lower side reflection surface 42e protruding outward (front side) and the left and right side edges of each of the reflection surfaces 42a to 42e are formed so as to expand toward the right frame portion 35 of the design drum 34, and the visible display The right side reflection surface 42f, which is a curved surface that protrudes outward (front side) as it approaches the portion 15, and the outward (front side) as it approaches the visible display portion 15 while expanding toward the left frame portion 36. Protruding curve It is composed of a left side reflection surface 42g that is the. Thus, the auxiliary reflecting surfaces 42d, 42e, 42f, and 42g receive light from the LED 41a and reflect the light toward the symbol stop line T side in the fluoroscopic display body 22.
[0037]
Each of the second openings 43 is formed between the main reflecting surfaces 42a, 42b, 42c and the left reflecting surface 42g, as shown in FIG. 5, FIG. 6, or FIG. The LEDs 41a inserted through the first opening 32f of the base member 32 are aligned with the front surfaces of the main reflecting surfaces 42a, 42b, and 42c, and are covered with the left reflecting surface 42g. The 34 symbols are not directly illuminated.
[0038]
[Effect of the embodiment]
Next, the operation of the drum-type symbol display device for gaming machines according to the embodiment will be described. When the base member 32 is disposed on the wiring board 30, the arcuate edge 31 a of the installation part 31 in the wiring board 30 is provided with a semicircular plate surface 32 a that aligns with the installation part 31. The arc-shaped regulating piece 32b formed on the base member 32 is brought into contact with the outside (the right side of the wiring board 30). At this time, the arc-shaped restricting piece 32b in the base member 32 is formed in an arc shape that matches the outer contour of the arc-shaped end edge portion 31a in the wiring board 30. The base member 32 is not easily displaced in the vertical direction in a state where the base member 32 is in contact with the portion 31. Further, since the plurality of LEDs 41a arranged in the installation portion 31 are inserted into the first opening portion 32f opened on the plate surface 32a of the base member 32, the base member 32 does not move forward. . As described above, since the base member 32 can be easily positioned with respect to the wiring board 30 without using bosses and holes, the workability is improved and the cost can be kept low. Is possible.
[0039]
Further, as shown in FIG. 1 or FIG. 6, a mounting portion 33 protruding rightward is formed at a position below the base member 32, and a detection sensor 48 is disposed on the end surface of the mounting portion 33, thereby detecting The sensor 48 can be positioned at a position separated from the base member 32 (wiring board 30) in the right direction by a required distance (in the vicinity of the connection fixing portion 39). That is, when attaching the detection sensor 48 to a position separated from the wiring board 30, it is not necessary to use the boss and the hole, so that the operation can be easily performed and the increase in cost can be prevented. Further, since the detection sensor 48 is positioned in the vicinity of the index 46 (in the vicinity of the connection fixing portion 39), the length of the detection piece 46b of the index 46 detected by the detection sensor 48 can be shortened. . That is, by causing the detection sensor 48 to approach the support 46a of the index 46 and shortening the detection piece 46b of the index 46, the detection piece 46b is bent when the symbol drum 34 is rotated. Therefore, the original position of the design drum 34 can be detected accurately.
[0040]
An arc-shaped end edge (an edge of the left-side reflecting surface 42g) of the reflector 42 that reflects the light of the plurality of LEDs 41a disposed in the installation portion 31 is brought into contact with the arc-shaped regulating piece 32b of the base member 32. By doing so, the forward movement of the reflector 42 is restricted, and the reflector 42 is positioned with respect to the base member 32 (wiring board 30). That is, as described above, the reflector 42 can be positioned with respect to the base member 32 without using a boss and a hole, so that workability can be improved and an increase in cost can be suppressed. In addition, since the detection sensor 48 and the reflector 42 can be positioned with respect to the wiring board 30 by the same base member 32, the number of parts can be reduced and the labor of the operation can be reduced.
[0041]
The plurality of LEDs 41a are inserted into the second opening 43 provided in the reflector 42 through the first opening 32f of the base member 32. The movement is restricted and the reflector 42 can be positioned at a predetermined position. Then, the base member 32 is positioned on the wiring board 30, and the fixing member 44 positioned on the reflector 42 is screwed to the wiring board 30 with the reflector 42 positioned on the base member 32. Since it did in this way, work efficiency can be improved and an assembly | attachment can be performed easily.
[0042]
The reflector 42 is composed of main reflecting surfaces 42a, 42b, and 42c, and auxiliary reflecting surfaces 42d, 42e, 42f, and 42g, and the light from each LED 41a is surface-reflected so that the visible display section 15 (each Since the design of the design drum 34 passing through the design stop line T) is illuminated, the entire design can be brightly displayed with uniform brightness, and the effect of production can be improved. Furthermore, since each LED 41a is inserted through the second opening 43 of the reflector 42 and surrounds the side portion of the LED 41a, the light irradiated to the side of each LED 41a is blocked. The pattern is not directly irradiated with the light. That is, only the reflected light that is reflected by the reflecting surfaces 42a, 42b, 42c, 42d, 42e, 42f, 42g of the reflector 42 irradiates the design of the design drum 34. For this reason, there is no wobbling of the pattern illumination spots, and it is possible to produce an illumination effect with a uniform luminance on the symbols on each symbol stop line T.
[0043]
The main reflecting surfaces 42a, 42b and 42c are composed of an upper reflecting surface 42a, a central reflecting surface 42b and a lower reflecting surface 42c which are sequentially inclined in the circumferential direction at a required interval, and correspond to the reflecting surfaces 42a, 42b and 42c. Since each of the LEDs 41a is disposed, the LED 41a can irradiate light independently for each of the reflecting surfaces 42a, 42b, and 42c. Therefore, even when a plurality of symbol stop lines T are provided in the visible display unit 15, bright display can be performed for each symbol stop line T. Further, the second openings 43, 43, 43 opened in the reflector 42 are vertically divided by the partitions 43a, 43a to correspond to the upper reflective surface 42a, the central reflective surface 42b, and the lower reflective surface 42c, respectively. For example, when the LED 41a irradiates light to the central reflecting surface 42b, the upper reflecting surface 42a and the lower reflecting surface 42c are not irradiated with light.
[0044]
Furthermore, in the drum-type symbol display device 20, the connector connection port 30 a formed at the upper position on the rear side of the wiring board 30 is exposed to the outside from the insertion hole of the rear case 24, and the rear side of the wiring board 30 is By inserting the lower position between the restricting protrusions 24b, 24b of the rear case 24, the rear side of the symbol display unit U is positioned and fixed. Further, the positioning protrusion 32e of the base member 32 attached to the wiring board 30 is engaged with the groove 22b of the transparent display body 22, and the positioning recess 32d of the base member 32 is replaced with the protrusion of the front case 25. By engaging with 25b, the symbol display unit U is held upright in the drum case 21 with its front and rear sides positioned and fixed.
[0045]
Thus, the symbol display unit U can be accommodated and fixed in the drum case 21 without screwing with screws or the like, and the assembling work becomes easy. Since the notch 32g is formed in the protrusion 32c in which the positioning recess 32d is formed, the protrusion 32c is positioned by engaging the notch 32g with the wiring board 30. For this reason, the bending of the projecting portion 32c is prevented, and the positioning recess 32d and the projecting portion 25b of the front case 25 can be easily positioned. Further, since the arc-shaped end edge 31a of the wiring board 30 is in contact with the inside of the portion of the base member 32 that extends leftward from the plate surface 32a of the arc-shaped regulating piece 32b, the drum case When the symbol display unit U is accommodated in 21, the wiring board 30 is not visible to the player from the visible display portion 15, and the design of the pachinko machine P is not deteriorated.
[0046]
The configuration of the drum-type symbol display device is not limited to that of the embodiment, and various changes can be made. For example, the mounting portion for attaching the position detection body is formed at a position below the base member, but may be formed at another position. Furthermore, although the stepping motor and the base member are attached to the right surface of the wiring board, they can be attached to the left surface side. And although the said index was formed in L shape, you may make it extend only linearly. In this case, position detection means for detecting the position detection body may be arranged so as to open to the position detection body side so that the position detection body passes between the light emitting unit and the light receiving unit. Moreover, as a light-emitting body, it is not restricted to LED, Various light-emitting bodies, such as a bean ball, can be used. Furthermore, the reflector member is provided with three reflecting surfaces as an upper reflecting surface, a central reflecting surface, and a lower reflecting surface as main reflecting surfaces, and is configured to reflect light in three directions, but two or four or more reflecting surfaces are provided. You may make it comprise with a reflective surface and should just determine according to the symbol stop line provided in the said visible display part.

However, the cutout portion may be formed near the lower end portion of the base member. By forming at least one of the upper end and the lower end, the position of the base member relative to the wiring board can be regulated. The first engaging portion provided at the upper end portion of the base member is also formed on at least one of the upper end portion and the lower end portion of the base member, and is detachably engaged with the first engaging portion. If the second engaging portion is formed in the housing case, the wiring board can be positioned by the engagement between the first engaging portion and the second engaging portion. And although the case where the drum type symbol display device which rotates a symbol drum was used as a rotary symbol display device was demonstrated, it is not restricted to this, A belt type and other conventionally well-known apparatuses can be used. Further, the case where the rotary symbol display device is provided in a general pachinko machine as a gaming machine has been described, but the present invention is not limited to this, and can be suitably used for a slot machine machine or the like.
