BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable symbol display device for a symbol combination game machine, and more specifically, it develops a symbol combination game based on variable control conditions using pachinko balls, coins and the like. The present invention relates to a rotary belt type variable symbol display device capable of expressing a jackpot state which is advantageous to a player when a preset combination condition of symbols is satisfied, and a winning state.

2. Description of the Related Art In a gaming machine of this kind represented by a pachinko machine with a design or a slot machine, a design variable display device in the form of a design drum is generally adopted as an entity display unit for a design combination game. In this device, as a basic configuration thereof, a stepping motor, a pattern drum in which various symbols and one reference index are arranged, and a detection unit for the reference index are included in each symbol unit. This unit is made into a unit display device by making a plurality of base units.
And in the symbol combination game by this device,
Based on the input / output control process on the electronic control unit side in response to the starting condition, the design drum is rotated according to the pulse drive of the motor of the design unit for each row, and the motor is stopped after the detection of the reference index by the detection means. Accordingly, the design drum is stopped at a predetermined position. Based on the result of the combination determination of the symbols displayed in this way, it is possible that a special game or a winning combination will appear in each gaming machine.

As for the variable symbol display device of the symbol combination type gaming machine which has been used for playing games up to today, only the symbol drum type as described above has been generalized and widely practiced. In this display device, since the pattern drum is directly connected to the stepping motor and rotated, one step angle (1
It is relatively easy to design and manufacture, including indexing the displacement angle) and the rotational displacement of the design drum for one frame. However, if the number of types of symbols and the number of frames are increased, and if it is attempted to increase the size of each frame, the size of the symbol drum will inevitably increase and a large motor will be required. Therefore, there are major problems that cannot be suitably implemented. Therefore, in reality, under the condition that it matches the configuration and size of the game machine, the size of the design drum
(Diameter), the number of pieces of the design, etc. were limited and produced, and in connection with this, it was not possible to sufficiently respond to the diversification of the display contents of the design combination game.

In such a situation, as one of other types that can solve the problems inherent in the above-mentioned display device in the form of a design drum, a display device in the form of a design belt is newly found in recent years. . According to this display device, the size in the front-rear direction (depth direction) of the symbol units in each row can be considerably reduced, and the length of the entire circumference of the symbol belt can be increased. The design becomes usable, and it can be suitably implemented based on the design and design variation control mode basically similar to the design drum form.

[0005]

However, in the design variable type display device of the design belt type according to the conventional proposal, the structure is complicated, or the size and size are complicated to manufacture and handle, and the design belt is long. Suitable pattern change due to
There was an inherent difficulty in not being able to display a stop indication. In addition, there is a problem that static electricity is generated due to friction between the rotating body on which the design belt is mounted and the belt, and the design belt is thereby charged and dust is attached. Further, due to the contact between the rotating body and the design belt, the dirt such as dust is pressed and condensed. That is, there is a serious problem that the detection mark arranged on the design belt cannot be reliably detected due to the above-mentioned stains that have been pressure-bonded and condensed, which hinders the movement / stop control of the design belt.

[0006]

SUMMARY OF THE INVENTION The present invention has been proposed in order to suitably solve the above-mentioned problems, and it is intended to reduce the weight and size of the entire apparatus, to facilitate the manufacture and handling, and to remove the dirt attached to the design belt. Therefore, it is an object of the present invention to provide a rotary belt type variable symbol display device capable of developing a suitable symbol combination game including stable movement and stop of the symbol belt.

[0007]

[Means for Solving the Problems] Overcoming the above-mentioned problems,
In order to preferably achieve the intended purpose, the present invention is a plurality of rows of rotary belt type symbol units independently having a symbol fluctuation stop display function, and necessary input / output control relating to the symbol fluctuation stop display of each symbol unit.

The illuminating device and the illuminating device that can be installed are configured in a set plate unit, and a removing member for dust or the like adhering to the detection mark portion is disposed at a required position on the rotational movement of the design belt. Characterize.

[0008]

The rotary drive control mechanism including the drive motor and the plurality of rotating bodies, the detecting means, and the illuminating device are installed at predetermined positions on one set plate, and an endless pattern belt is provided between the outer circumferences of the rotating bodies. By spreading and hanging, each pattern unit can be easily configured and manufactured by making each set plate lighter and smaller. Further, such a symbol unit can be set in parallel by plural units as a set by connecting the respective set plates in parallel and can be configured as a symbol display device for each one and can be easily handled. . And in the implementation in the target gaming machine, in the symbol variation of each symbol unit based on the control condition from the control circuit device, in the process of continuously moving the symbol belt in the predetermined direction according to the drive of the rotation drive control mechanism, Dust and the like adhering to the detection mark portion of the design belt is removed by the removing member. Thereby, the detection mark is properly detected by the detection means. Further, the brush portion made of the conductive fiber comes into contact with the pattern belt, so that the charge of the pattern belt is removed and the adhesion of dust due to the charge is reduced.

The set plate 11 is a printed circuit board type molded from a synthetic resin plate material containing glass fibers, and mounting holes and heat dissipation holes are formed in each part, while one side surface (outer surface) is illustrated. 4. A motor circuit 12, a detection circuit 13, an illumination circuit 14 and the like, which are schematically indicated by broken lines in FIG. 4, are separately configured, and the ends of these circuits 12, 13, 14 are located after the set plate 11. It is connected to each pin of one connector 15 installed on the side.

Further, in the rotation drive control mechanism 16, a stepping motor (simply a motor) which is fixed to a predetermined position on the outside of the set plate 11 (on the right side in FIGS. 3 and 5) by a screw 66 or the like and is connected to the circuit 12. 17), a large-diameter main pulley 19 connected and set to the motor 17 on the inner side of the set plate 11 (on the left side in FIGS. 3 and 5), and a horizontal position at a predetermined axial center position with respect to the main pulley 19. A small-diameter secondary pulley 20 positioned and supported by a fixed support shaft 21 is mainly used, and a guide tool 22 having a tension adjusting guide pulley 26 is attached to a rear portion between the pulleys 19 and 20. Then, the motor 17 sets the seat 62 to the set plate 11

The resin-made cylindrical guide pulley 26 supported by the support shaft 27 of the arm 23 is
It is possible to guide in an appropriate stretched state by appropriately press-contacting from inside.
However, in this guide tool 22, the guide pulley 26 together with the arm 23 can be displaced to the non-guide position by the fingertip operation.
Further, the guide pulley 26 has a taper shape in which both outer peripheral ends are loose.

The design belt 28 is formed as an endless belt having extremely high tensile strength and small expansion and contraction by welding both ends of a design display band B, which will be described later in FIG.
The rotary drive control mechanism 16 is mounted and set as shown in FIGS. 4 and 6 over the outer circumferences of the rotary bodies 19, 20, and 26. The belt 28 is properly stretched and held by the urging force acting on the guide pulley 26, and is constantly stretched over the outer surface of the main pulley 19 for a half circumference thereof. Between the front belt portion 28a and the guide pulley 26.
It is in a substantially parallel state with b. While being held in such a stretched state, the belt 28 itself is prevented from slackening, slipping with the main pulley 19, etc., so that the belt 28 can be stably and lightly rotated. This pattern belt 2
8 is an endless belt that is appropriately longer than the circumferential length between the main pulley 19 and the sub pulley 20, and uses the switching displacement of the guide pulley 26 to quickly and easily thread it (replacement / replacement).
it can.

The symbol display band B, which is the base of the symbol belt 28 described above, is specifically two transparent ultra-thin film-like materials (for example, polyester, having high tensile strength and small change in expansion and contraction).
An inner layer having a thickness of 25 to 40 μm is laminated and is formed into a predetermined size (length, width) based on a predetermined print cutting process. Then, in the width direction of the display band B, as shown schematically in FIGS. 7 and 8, a plurality of types of symbols 29 (for the sake of convenience are abbreviated by alphabetical characters) including a hitting and a detaching pattern.
Is formed by printing with an ink agent of each color having high sensor sensitivity (light transmissivity) by the detection means 31, and is divided into a plurality of frames (see the numbers 0 to 20 in the figure) at the pattern center interval P indicated by the one-dot chain line in the figure. They are arranged in an appropriate order. Further, in one side portion of the display band B, one reference mark 30 and a plurality of symbol marks 30a are provided as detection marks detected by the detecting means 31 at required positions for one reference symbol and each symbol selected appropriately. Are formed by partial vapor deposition of a vapor deposition material having a low sensor sensitivity such as aluminum or chromium.

It should be noted that all the symbol marks 30a are formed and arranged at the center line position of each symbol with a detection size P ₂ for a predetermined pulse displacement amount of the symbol belt, while the reference mark 30 is one reference symbol (for example, "A"). ) Is formed with a detection size P ₁ (including one pattern mark) suitable for the detection interval of the two sensors 32 of the detection means 31 (see FIG. 8), and this mark 30,30a part,
It is thicker than the other portions of the design belt 28.
In addition, the numeral numbers “0 to 0” written in the figure of the symbol display band B
"20" means a counter value defined as a symbol number representing the positions and types (A to U) of all the symbols 29 for convenience as one of the processing controls on the program in the control circuit device E described later, and the detecting means. The position (time point) at which the reference mark 30 is detected by 31 is counted as a reference value "0" up to the final value "20" and reset to "0" again.

The pattern belt 28 formed by such a pattern display band B is a film belt having a very small mass, and is a joint surface between two transparent base materials (front base material and back base material). All patterns 29 and marks 30, 30 formed on
Since a can be clearly seen from the outer surface of the belt, no special equipment is required for each printing or vapor deposition condition, quality of modules, etc. It can be checked quickly and easily by visual inspection, and the pattern 29 and the marks 30 and 30a are prevented from being peeled off or dropped during handling and use of the pattern display body B, so that the pattern display body B can be suitably used for a long time. Further, the mutual sensor sensitivity (light transmissivity) of the design 29 and the respective marks 30, 30a
By utilizing the difference, each mark can be formed and arranged at a required position without being restricted by all the patterns, and even if there is a case where it overlaps with a part of the pattern, its non-light transmission condition Properly detected while maintaining (light blocking state). As a result, the required pattern 29 is provided with the respective marks 30, 3
It can be formed to be large over the entire width of the belt without being restricted to the position of 0a, and can be easily implemented as a preferable information mark type pattern display material that is colorful and has a good appearance.

On the other hand, the detecting means 31 is the pattern belt 28.
When the reference mark 30 is detected during the continuous movement of the
Positioning reference detection is performed for each rotation, and the pattern mark 30a at each position is detected one by one based on this detection time, and an optical sensor 32 (two shown) having a light emitting portion and a light receiving portion is used. To be done. Then, as a detection position in consideration of the position of the reference pay line 5, as shown in FIG. 3, FIG. 4 and FIG.
Are installed in parallel above the front band portion 28a and connected to the circuit 13. The detection means 3
1 is detected (code signal "1") when both the light transmission type sensors 32 exhibit a non-light transmission state (light shielding state) with respect to the reference mark 30 and the pattern mark 30a. And

Further, in the lighting device 33, the setting plate 1
In the inside of 1, a lamp base 34 connected and fixed to a predetermined portion of the circuit 14 is assembled with a hopper-shaped light diffusion cover 35 that is hooked at the center of the front edge of the set plate 11. A plurality of lamps 36 arranged in 34
Is accommodated in the center of the cover 35 in a forward direction, and the pattern is directly illuminated from the inside. In addition, as each lamp 36, an LED lamp or a round fluorescent lamp having a required emission color can be preferably used.

As described above, each of the symbol units U constituted by one set plate 11 unit has a screw hole 38 and a screw shaft 39 at both ends as illustrated in FIG. By using the connecting rod 37 that also serves as a spacer rod and is slightly longer than the axial length, the corresponding set plates 11 can be easily assembled and set. That is, as schematically shown in FIG. 9 as an example, the three units U shown in the figure are set in the standing state in the same direction, and the connecting rods 3 are inserted into the holes 40 of the set plate 11 in the right column.
Align the screw holes 38 of 7 and screw 4 from the outside of the set plate 11.
Tighten 1. Next, the holes 40 of the set plate 11 in the middle row are aligned with the screw shafts 39 of the connecting rods 37 in the right row, and the connecting rods 37 in the middle row are inserted into the screw shafts 39 through the screw holes 38. connect. Then, each hole 40 of the set plate 11 in the left row is similarly aligned with the screw shaft 39 of each connecting rod 37 in the middle row, and the nut 42 is tightened to the screw shaft 39 from the side of the set plate 11 in the left row. . As a result, the units U are assembled and set so that the set plates 11 are in parallel with each other in a column-parallel state, and become one set of the substantial display section of the display device M (see FIGS. 3 and 5).

In such a substantial display section, the gap between the set plate 11 of each row and the main pulley 19 can be assembled with a minimum gap, and even if the motor 17 of the right row in the figure is exposed to the outside,
Since the motors 17, 17 in the middle row and the left row can be inserted into the inner diameter from one opening surface of the main pulleys 19, 19 in the right row, the middle row, the three-row symbol unit U is the most necessary. Can be set with a small width. And the entity display section is the same as the container 43.
By positioning and locking the set plate 11 of each of the symbol units U in the inside, it is possible to easily handle one group by one container 43 unit, and on the back side of the game board 60 of the pachinko machine P. On the other hand, positioning and setting can be easily performed in units of the containing body 43 (see FIGS. 2 to 5). In this state, the front band portion 28a of the design belt 28 in each row is the transparent display body 1
In addition, the connection tool 15 of each set plate 11 is exposed on the back side of the housing body 43 and can be easily connected to the input / output control section of the control circuit device E, which will be described later, equipped on the pachinko machine via the connection line H. It can be connected (see Fig. 5).

As for the container 43, as shown in FIGS. 2, 4 and 5, a front frame member 44 is directly fixed to the rear surface of the game board 60 and is assembled and aligned with the transparent display member 1.
An example is an assembly type of a rear frame body 47 which is aligned and fixed to the back side of the front frame body 44. In the front frame body 44,
A window 45 having a size that matches the transparent plate 3 is opened, and a positioning locking portion 46 for the set plate 11 of each symbol unit U is formed inside the window 45. On the other hand, the rear frame body 47 has an insertion opening 48 and a heat radiation opening 49 for the connection tool 15 of each set plate 11 on the rear surface thereof, and a positioning locking portion 50 formed inside thereof. Then, on one side (the right side in FIG. 5) of the combined surface of both 44 and 47, the motor 17 in the symbol unit U in the right column
The escape protection portion 43a is molded. It should be noted that the rear frame 47 may include a base and accessory parts (not shown) as necessary.
Can be attached.

Here, setting items related to the design belt 28 will be additionally described as reference examples. That is, one displacement amount per pulse by the number of pulses (however an integer) set for one rotation of the motor 17 and the circumference of the main pulley 19, and the circumference of the main pulley 19 and the effective circumference of the belt 28. The total number of pulses required for one rotation of the belt is obtained in advance based on the ratio of. Under this condition, the total number of pulses is set to an integer closest to the calculated value in advance, and the belt 28 can be designed and manufactured to have a decimal length (for example, 1 /
A plan to make the effective circumference including up to 10 mm), or belt 2
It is possible to select a scheme in which 8 is set as an integer effective circumference in advance, and the total number of pulses corresponding to this is rounded off to the nearest decimal place to obtain an integer. Then, based on any one of the selection plans, the basic pitch of the symbol interval to be carried out and the number of frames of the symbol are basically indexed from the effective circumference of the belt 28, and the reference pulse number by the basic pitch ÷ 1 pulse displacement amount is calculated. It is calculated, and an integer corresponding to the reference pulse number is set as the basic pulse number in the unit of one symbol, and the symbol belt 28 is continuously moved and stopped. As a result, the deviation of the entire belt due to the difference between the theoretically calculated value and the actual value and the display deviation for each symbol can be stopped at the minimum value close to "0". Under this condition, the detection means 31 detects the reference mark 30. All the symbol positions from the reference position (when the counter "0" is reset), each mark is directly detected based on the basic pulse number unit, stable movement of the symbol and accurate stop display on the winning line 5 It can be planned.

Regarding the design belt 28 in relation to the above-mentioned setting conditions, even if the stop display positions (center line positions) of the respective designs 29 with respect to the reference pay line 5 are deviated, The error is, as the maximum value when viewed strictly, only a minute value range depending on the one pulse displacement amount. Therefore, this minute error can be substantially set within the tolerance range, and it can be regarded as a stop display at the center line position of the symbol with respect to the pay line 5 without any problem. Therefore, when the design belt 28 is applied, the design belt 28 can be freely applied without being restricted by the position of the design with respect to the main pulley 19 and the reference adjustment, and the trouble and troublesomeness can be avoided, and the small motor 17 can be avoided. But the design belt 2
8 can be easily rotated. In addition, when looking at the detection position of the detection means 31, the position of the pay line 5 on the assumption that the respective symbols 29 for the pay line 5 are stopped and displayed by adjusting the center line position thereof within the above-mentioned tolerance range. Therefore, it can be set to a position based on 1 pulse displacement x set pulse number.

The basic input / output control system relating to the above-mentioned substance display section (three symbol units U) of the display device M is constituted by the control circuit device E which is shown in block diagram form in FIG. 11 as an example. Has been done. In this circuit device E, the winning determination unit 51, the random number data setting unit 52, the motor control unit 53, the pulse generation unit 54, and the counter unit 55 and the symbol detection unit 5 for each symbol display unit U.
6 is a basic main control unit, and as a basic symbol variation control mode of the display device M, an initial "symbol origin position confirmation control process" and a "symbol variation stop control process for the start signal input" In addition to achieving the required control mainly based on "," the symbol units U in the three columns shown in the figure can be subjected to fluctuation / stop control processing in a predetermined order, time, and shift conditions.

As a reference example, regarding the "symbol origin position confirmation control processing", in the example in which the symbol origin alignment in the three-row symbol unit U is displayed as "displacement", the winning determination unit 51 is provided when the power is turned on. Depending on the response with the random number data setting unit 52, one “offset initial data” related to the stop symbol in each column is selected and held in the winning determination unit 51. Under this data condition, drive control (pulse output) of the motor control unit 53 in response to an instruction from the winning determination unit 51.
Based on the above, the three rows of motors 17 are sequentially driven to rotate the design belt 28, while the winning determination unit 51 holds the detection condition of the design mark related to the detection stop design for each row.
Under this condition, after the set time, the detection means 31 of each row that has received the detection condition instruction from the winning determination section 51 detects the reference mark 30 of the pattern belt 28 for each row and becomes the "offset initial data". When the mark at the corresponding predetermined position (including both marks 30, 30a) is detected, the information is input to the winning determination unit 51 via the counter unit 55 and the symbol detection unit 56.

Then, after a set time from the end of the mark detection, in accordance with the drive control stop (stop of pulse output) from the motor controller 53, the pattern belt 28 is stopped together with the motors 17 in each row, and the pattern belt 28 is stopped. One symbol 29 is stopped and displayed on the pay line 5. In this result, the detection information content of the detection means 31 in each column is sequentially input to the counter section 55 and the symbol detection section 56, and the detected symbol mark and the counter value for the symbol mark.
(0 to 20) and the type of symbols 29 (A to U) are compared and converted, and finally the information is input to the winning determination section 51. It is confirmed and it waits as it is. In this “confirmation control process”, in addition to the “offset initial data” process system described above, a “time control data” process system based on a temporal process condition between the winning determination unit 51 and the motor control unit 53. Can also be suitably adopted.

On the other hand, the "symbol fluctuation stop control process" is performed for a start signal input generated during a pachinko game. That is, the pattern belt 28 is rotated according to the sequential drive of the three rows of the motors 17 by the pulse output transmitted from the motor control unit 53 based on the instruction from the winning determination unit 51 for one start input, while the random number is generated. In the data setting section 52, 1 for the stop symbol for the start input
Two “sampling data” are selected. For this "sampling data", all the marks 3 on the symbol belt 28 are selected from the total number of all symbol combinations.
Corresponding to the information content of the drawing number counter value corresponding to 0, 30a, it is determined to be any one of the data classified into the out-of-range and the out-of-range, and the input is temporarily suspended in the winning determination section 51. Next, in the processing instruction of the winning determination section 51, the detection means 31 at the final stage in which the symbol belt 28 is rotated at a low speed according to the sequential deceleration driving of the motors 17 in each row based on the drive control of the motor control section 53. Based on the detection conditions defined by "sampling data", for example, the symbol mark 30a at a predetermined position is detected from the detection reference time point of the reference mark 30,
Information is input to the winning determination section 51 via the counter section 55 and the symbol detection section 56.

Then, after a set time from the end of the detection, the pattern belt 28 is stopped together with the motors 17 in each row in accordance with the pulse output stop from the motor control section 53, and one symbol (hit) is detected for the symbol mark 30a, for example. 29) is stopped and displayed on the pay line 5. At this time, regarding the mark detection content of the detection means 31 of each column, any of the marks 3 detected from the detection time of the reference mark 30 in each counter unit 55.
The counter value corresponding to the position of 0, 30a is detected in the range of "0-20" and input to the symbol detection unit 56, and from the counter value detected by the detection unit 56, the type of the symbol 29 (A to U) ) Is detected and determined, and information is input to the prize determination section 51. Based on this, the determination unit 51 individually and globally determines each stop symbol based on the “sampling data”. As a result, for the symbol combinations on the pay line 5, for example, in the case of the same kind of winning symbols matching in three columns, "hit" is determined, and in all other cases, it is determined as "off (including out of reach)".

In this control process, one "sampling data" extracted from the random number data setting unit 52 is divided into one for preliminary hitting and one for deviation, as a method different from the above. A method in which data is determined and the input processing is divided into a hit processing section and a deviation processing section of the winning determination section 51 can also be suitably adopted. By the way, as an example of creating and setting "sampling data" according to this control processing example, a sequence of random numbers (random number 1) and deviating process number "numerical 2" are arranged in an appropriate order and are cycled at regular intervals (random number). Table) is adopted, and within this sequence, one "sampling data" having a hit or miss processing number at the time of start input is extracted.

The variable pattern display device M of this embodiment
According to the above, in the example of the symbol stop display by the above-described direct detection of the mark, the symbol belt 28 of the symbol unit U of each row
However, even if some error occurs in the amount of displacement corresponding to the number of basic pulses corresponding to each symbol frame, at the time when the detection means 31 detects that the predetermined detection marks 30, 30a are present, the counter value corresponding to this symbol 29 can be accurately detected and read, and the symbol 29 can be stopped and displayed on the pay line 5 after a predetermined time. In addition, regarding the combination of each symbol that is stopped on the pay line other than the standard pay line 5 (upper and lower horizontal lines and diagonal lines), with respect to the counter value related to each symbol on the standard pay line 5, Then, the detection value is determined based on the calculation process based on the counter value of "+1 and -1" (the set pulse number for one frame of the symbol). Further, the speaker 57 and the display lamp 36 illustrated in FIG. 11 generate respective sound effects and display light in accordance with the symbol fluctuation stop condition at the time of starting input.

In the symbol variable display device M of the present embodiment which can be constructed and implemented as described above, each symbol unit U
In each case, in consideration of the frictional charging (static electricity) of the rotating body of the rotation drive control mechanism 16 and the design belt 28, and the situation such as dirt (dust) attached to the design belt 28 due to the charging, these are preferably removed. The following configuration is added as a countermeasure.

First, regarding a part of the rotating body of the mechanism 16, mainly the main pulley 19 and the sub pulley 20,
The required size (diameter, axial length) of the conductive resin, for example, a base resin containing polypropylene as the main component, and a composite conductive resin material made by kneading and combining a conductive carbonaceous material.
It is a lightweight pulley that is well-balanced in terms of strength, electrical properties and moldability. And
As the outer peripheral surface shapes of the respective pulleys 19 and 20, as shown in FIGS. 12, 13, and 14, flange portions 71, 71 for belt swinging are formed at both ends of the entire length,
In the effective shaft length L, a large diameter contact portion 72 having a central portion axial length l ₁ that directly abuts a large portion in the width direction of the design belt 28 stretched as a substantial outer shape of the pulley, and both side edges of the belt 28. And small-diameter recessed escape recesses 73 and 73 having axial lengths l _{2 at} both ends for allowing the flexible deformation of the detection marks 30a and 30a to avoid contact with the thick detection marks 30 and 30a, respectively. The two parts 72, 73 are connected by the tapered surface parts 74, 74 having the axial length l ₃ .

According to this structure, the main pulley 1 and the sub pulley 1
It is possible to suitably suppress the generation of static electricity due to the rotational friction between the pattern belts 9 and 20 and to significantly reduce the electrification, and it is possible to eliminate dust adhesion due to electrification. Further, since the escape recesses 73 of both pulleys 19 and 20 can be used to avoid contact with the pattern belt 28, especially with the detection marks 30 and 30a, dust on the same portion or dust remaining on the same portion can be avoided. It is possible to suitably eliminate the pressure-bonding and solidification (see FIG. 13). Moreover, even if the pattern belt 28 used has a width size over the entire circumference thereof and is partially large including the welding margin portion at its side edge, both pulleys 19,
Since the flexure of both side edge portions of the belt is allowed by the relief recesses 73, 73 on both sides of the 20 (see FIG. 14), unnecessary rubbing between the flange portions 71, 71 on both sides and the belt side edge is eliminated. As a result, the pattern belt 28 can be properly and continuously moved in a stable stretched state.

On the other hand, a removing member 75 which also serves as a dust remover / zone remover is installed in the process of rotational movement of the design belt 28, specifically, a required portion of the front side belt portion 28a. This removal member 7
As shown in FIG. 3, FIG. 4, FIG. 6, and FIG. 15, the brush part 77 in which conductive fiber (nylon or the like) is planted in a cotton base cloth 76 is formed as a concrete example. Using the adhesive surface 78 provided on the back surface of the base frame 76, the upper right side of the cover 35 (the detecting means 31
Of the front side belt portion 28a on the back side of the belt, particularly the portion where the detection marks 30, 30a are located. Has become. Thereby, in the continuous movement of the pattern belt 28, the brush portion 7 of the removing member 75
7 can always contact with the positions of the detection marks 30 and 30a to suitably remove the electrostatic charge (air discharge), reduce the adhesion of dust due to the charging, and cleanly remove the adhered dust.

Therefore, in the variable design display device M of the present embodiment, which is provided with the above-mentioned countermeasures for removing static electricity and removing dust,
As a complementary effect of the configuration related to the main and slave pulleys 19 and 20 and the installation of the removing member 75, it is possible to prevent the generation of static electricity, prevent the electrification of the design belt 28, and detect marks 30 and 30a Since it is possible to prevent stains on the position of,
The detection marks 30 and 30a can always be maintained in a normal detectable state even during long-term use. Thereby, while the pattern belt 28 is moving, the detection mark 30,
It is possible to eliminate the detection failure of the detection means 31 due to the contamination of 30a in advance, and to achieve long and proper mark detection.
As a result, it is possible to perform a precise fluctuation / stop control of the symbol belt 28 and present a suitable symbol display and a combination game.
