[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a symbol variable display device for a symbol combination game machine, and more particularly, to a symbol combination game developed based on fluctuation control conditions using a pachinko ball, a coin or the like. The present invention relates to a rotating belt type variable symbol display device capable of expressing a big hit state or a winning state which is advantageous to a player when a predetermined combination condition of symbols is satisfied.

[0002]

2. Description of the Related Art In a game machine of this type typified by a pachinko machine with a symbol and a slot machine, a symbol variable display device in the form of a symbol drum is generally employed as an entity display portion for a symbol combination game. In this apparatus, as a basic configuration, a single pattern unit including a stepping motor, a pattern drum on which various patterns and one reference index are arranged, and a detection unit for the reference index is configured. This unit is made into a plurality of base units to form one unit display device.
And in the symbol combination game with this device,
The symbol drum is rotated according to the pulse drive of the symbol unit motor for each row based on the input / output control processing on the electronic control unit responding to the starting condition, 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 combination determination result of the symbols thus displayed, a special game or winning establishment can be realized in each of the gaming machines.

[0003] As for the symbol variable display device of the symbol combination type game machine used for the game to date, only the symbol drum type as described above has been generalized and widely practiced. In this display device, since the design drum is directly connected to the stepping motor and rotated, one step angle (1) with respect to the pulse output number of the motor is obtained.
The design and manufacture are relatively easy, including the indexing of the displacement angle) and the rotational displacement amount for one symbol of the symbol drum. However, if the number of patterns and the number of frames are increased, and the size of each frame is increased, the diameter of the pattern drum is inevitably increased and a large motor is required. Therefore, there is a major problem that cannot be suitably implemented. For this reason, in reality, the size of the design drum must be
(Diameter), the number of symbols are limited and the number of frames is limited to the production and implementation. In this connection, it has not been possible to sufficiently respond to the diversification of the display contents of the symbol combination game.

In such a situation, in recent years, a display device in the form of a symbol belt has been newly found as another type which can solve the problems inherent in the display device in the shape of the symbol drum. . According to this display device, the size of the symbol units in each row in the front-rear direction (depth direction) can be considerably reduced, and the entire circumference of the symbol belt can be lengthened. The design can be used, and can be suitably implemented based on a design and a design variation control mode basically similar to those in the case of the design drum form.

[0005]

However, in the design variable display device of the design belt type according to the conventional proposal, the structure is complicated, the size is large, the production and handling are complicated, and the length of the design belt is long. More suitable pattern variation due to
There was a difficult point that could not be displayed stop. Further, there is a problem that static electricity is generated due to friction between the rotating body on which the design belt is hung and the belt, thereby charging the design belt and adhering dust. Further, by the contact between the rotating body and the design belt, the dirt such as dust is pressed and condensed. That is, the detection mark arranged on the design belt cannot be reliably detected due to the contaminants condensed by crimping, and there is a serious problem that hinders the movement / stop control of the design belt.

[0006]

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

[0007]

The see-through board 3 is mounted, and the see-through board 3 is formed with three rows of display windows 4 on the left, middle, and right, and a plurality of winning lines 5 for symbol stop display. In addition, the display window 4 of each column can see through the symbols for each of the three frames shown in the drawing. For example, the center horizontal line is set as a reference line. Each part of the transparent display 1 includes a holding lamp 6 for displaying the number of valid holdings (for example, up to four) of the starting input conditions, and a display lamp for decorative light displayed according to the design display contents. 7 and the like are provided. The see-through plate 3 is preferably formed of a colored transparent resin material containing an antistatic agent.

On the other hand, in the three symbol units U, which are the actual display sections of the display device M, as shown in FIGS. A rotation drive control mechanism 16 having a plurality of rotating bodies including a drive motor 17 and a tension adjusting member arranged in
A mark-type pattern belt 28 made of film, which is stretched and hung endlessly around the rotating body of the mechanism 16; an optical detecting means 31 for detecting the position of the symbol in the process of moving the symbol belt 28; It has a lighting device 33 for appropriately illuminating the design in the front side band portion of the design belt 28 from the inside, and each unit can be made lightweight and compact by the set plate 11 as a unit and can be easily configured and manufactured. The set plate 11 is of a printed circuit board type formed of a synthetic resin plate material containing glass fiber, and has a mounting hole, a heat radiating hole, and the like formed in each portion, and a drawing on one side (outer surface) thereof. 4, a motor circuit 12, a detection circuit 13, a lighting circuit 14, and the like, which are schematically indicated by broken lines, are separately configured, and the ends of these circuits 12, 13, and 14 are located behind the set plate 11. It is connected to each pin of one connector 15 installed on the side.

In the rotary 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 (right side in FIGS. , A large-diameter main pulley 19 connected and set to the motor 17 inside the set plate 11 (left side in FIGS. 3 and 5), and a horizontal A small-diameter slave pulley 20 positioned and supported by a fixed support shaft 21 is mainly used, and a guide tool 22 having a guide pulley 26 for adjusting tension is attached to a rear portion between the pulleys 19 and 20. Then, the motor 17 moves the seat plate 62 to the set plate 11.
Is closely positioned in the circular hole 61 of the motor shaft 6 and is fixed.
The rotary disk 64 connected to the rotary disk 3 extends inward through the circular hole 61, and the main pulley 19 is connected to the rotary disk 64 by aligning the center connection seat 65 to the rotary disk 64 and connected by screws 67. In the guide tool 22, an arm 23 is supported by a support shaft 24 fixed and extended horizontally inside the set plate 11, and a spring 25
The resin-made cylindrical guide pulley 26 supported by the support shaft 27 of the arm 23
It can be guided in an appropriate stretched state by appropriately pressing from the inside.
However, this guide tool 22 enables the guide pulley 26 to be displaced to the non-guide position together with the arm 23 by a fingertip operation.
The guide pulley 26 has a tapered shape at both ends of its outer periphery.

The symbol belt 28 is formed by welding and joining both ends of a symbol display band B which will be described later schematically shown in FIG.
As shown in FIGS. 4 and 6, the rotary drive control mechanism 16 is mounted around the outer circumference of each of the rotating bodies 19, 20 and 26. The belt 28 is always stretched over the outer half of the outer surface of the main pulley 19 while being appropriately stretched and held as a whole by the urging force acting on the guide pulley 26. Between the front band portion 28a and the guide pulley 26.
b is in a substantially parallel state. Under such an extended hanging state, slack of the belt 28 itself and slippage with the main pulley 19 are avoided, so that the belt 28 can be stably and lightly rotated. This design belt 2
8 is based on the premise that the endless belt is appropriately longer than the circumferential length between the main pulley 19 and the slave pulley 20, and is quickly and easily passed through by using the switching displacement of the guide pulley 26 (removal and replacement).
it can.

The symbol display band B, which is the base of the symbol belt 28 described above, is specifically composed of two transparent ultra-thin film-like materials (for example, polyester,
It is formed into a predetermined size (length, width) based on a predetermined print cutting process using a laminate having an inner thickness of 25 to 40 μ). Then, in the width direction of the display band B, as schematically shown in FIGS. 7 and 8, a plurality of types of symbols 29 including a hit and a miss are provided (abbreviated in alphabetical characters for convenience).
Are formed by printing with inks of each color having a high sensor sensitivity (light transmission) by the detecting means 31, and are formed for a plurality of frames (see the reference numbers “0 to 20”) at the symbol center interval P indicated by a dashed line in FIG. They are arranged in an appropriate order throughout. In one side portion of the display band B, one reference mark 30 and a plurality of each symbol 30a are provided as detection marks detected by the detection means 31 at required positions for one reference symbol and each symbol selected as appropriate. Are formed by partial vapor deposition of a vapor deposition material having a low sensor sensitivity, such as aluminum or chromium.

[0016] Note that all symbols marks 30a are formed arranged in detection size P ₂ for a given pulse displacement amount of symbols belt centerline positions of the symbols, whereas the reference marks 30 are one reference symbol (for example, "A" ) Is formed at a detection size P ₁ (including one symbol mark) suitable for the detection interval of the two sensors 32 of the detection means 31 (see FIG. 8), and this mark is formed. 30, 30a part,
It is thicker than other parts of the design belt 28.
In addition, the numeral number “0” written in the figure of the symbol display band B
"20" means a counter value defined as a symbol number representing the position and type (AU) of all symbols 29 for convenience as one of the processing controls on the program in the control circuit device E to be described later. 31 is counted as the reference value "0" at the position (time point) at which the reference mark 30 is detected, counted to the final value "20", and reset to "0" again.

The design belt 28 formed by such a design display band B is a film belt having a very small mass, and a joining surface of two transparent base materials (a front base material and a back base material). All symbols 29 and marks 30, 30 formed on
a can be clearly seen from the outer surface of the belt, so that the inspector himself does not need any special equipment for the quality of each printing or vapor deposition, the quality of the module, etc. It can be quickly and easily confirmed through visual recognition, and furthermore, during the handling and use of the symbol display body B, the symbol 29 and the marks 30, 30a are completely prevented from being peeled off or dropped, so that they can be used for a long time. In addition, the sensor sensitivity (light transmission) of the symbol 29 and each of the marks 30, 30a.
By utilizing the difference between the marks, each mark can be formed and arranged at a required position without being restricted by all the symbols. (Light blocking state) is detected properly. As a result, the required symbols 29 are marked with the respective marks 30, 3
It can be formed to be large over the entire width of the belt without being restricted by the position of 0a, and can be easily implemented as a colorful, good-looking, and suitable information-marking pattern display material.

On the other hand, the detecting means 31 comprises a symbol belt 28.
When the reference mark 30 is detected during the continuous movement of
A positioning reference is detected for each rotation, and the symbol 30a at each position is detected one by one based on the time of the detection, and an optical sensor 32 (two shown) having a light emitting part and a light receiving part is used. Is done. As a detection position in consideration of the position of the reference winning line 5, as shown in FIGS. 3, 4, and 6, the symbol belt 28 inside the set plate 11 is used.
Is installed in parallel with the upper part of the front side band portion 28a, and is connected to the circuit 13. Detecting means 3
Reference numeral 1 denotes detection (code signal “1”) when both the light transmission type sensors 32 exhibit a non-light transmission state (light blocking state) with respect to the reference mark 30 and the design mark 30 a. And

In the lighting fixture 33, the set plate 1
A hopper-like light diffusion cover 35 hung on the center of the front edge of the set plate 11 is attached to a lamp base 34 connected and fixed to a predetermined portion of the circuit 14 inside the lamp base 1. A plurality of lamps 36 arranged at 34
Are forwardly accommodated in a central portion in the cover 35 so as to directly illuminate the design from the inside. As each lamp 36, an LED lamp or a round fluorescent lamp having a required emission color can be suitably used.

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

In such a solid display portion, the gap between the set plate 11 in each row and the main pulley 19 can be minimized and assembled, and even if the motor 17 in the right row in the figure is exposed to the outside,
Since the motors 17 in the middle row and the left row can be inserted into the inner diameter from one opening face of each of the main pulleys 19 in the right row and the middle row, the symbol units U in the three rows are necessary. Can be set with a small width. Then, the entity display unit is provided with the container 43.
The set plates 11 of the respective symbol units U are positioned and locked therein, so that one set can be easily handled one by one unit of the housing 43, and 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 container 43 (see FIGS. 2 to 5). In this state, the front side band portion 28a of the symbol belt 28 in each row is
And the connecting members 15 of the respective set plates 11 are exposed on the back side of the housing 43, and easily connected to an input / output control unit of a control circuit device E described later provided in the pachinko machine via a connecting line H. It can be connected (see FIG. 5).

As shown in FIGS. 2, 4 and 5, a front frame 44 fixed directly to the back of the game board 60 and assembled and aligned with the transparent display 1 as shown in FIGS.
And a rear frame 47 that is aligned and fixed to the back side of the front frame 44. In the front frame 44,
A window 45 having a size matching the see-through plate 3 is opened, and a positioning locking portion 46 for each symbol unit U with respect to the set plate 11 is formed inside the window 45. On the other hand, the rear frame 47 has an opening 48 and a heat radiating opening 49 for the connector 15 of each set plate 11 on the back surface thereof, and a positioning locking portion 50 formed inside thereof. The motor 17 in the symbol unit U in the right row is provided on one side (the right side in FIG. 5) of the combination surface of the two 44, 47.
Is formed. The rear frame 47 has a base and attached parts (not shown) as necessary.
Can be attached.

Here, setting items related to the symbol belt 28 will be additionally described as a reference example. That is, one displacement amount per pulse based on the number of pulses (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. Under this condition, the total number of pulses is set to an integer closest to the calculated value in advance, and a decimal length (for example, 1 /
Proposal for effective circumference including up to 10mm) or belt 2
It is possible to select a plan in which 8 is set to an integer effective circumference in advance, and the total number of pulses corresponding to this is rounded to the whole number by rounding down the calculated value to the decimal point. Then, based on one of these selection plans, the basic pitch of the symbol interval to be implemented and the number of frames of the symbol are basically determined from the effective circumference of the belt 28, and the reference pulse number based on the basic pitch divided by one pulse displacement is calculated. The calculated number is set to an integer closest to the reference pulse number as a basic pulse number for each symbol frame, and the symbol belt 28 is continuously moved and stopped. As a result, the deviation of the entire belt and the display deviation of each symbol due to the difference between the theoretical calculation value and the actual value can be kept to the minimum value close to "0". From the reference position (when resetting the counter "0"), all the symbol positions are directly detected based on the basic pulse number unit, and the symbols are moved stably and the accurate stop display on the winning line 5 is achieved. I can figure it out.

When the symbol belt 28 is viewed in relation to the above-described setting conditions, even if the stop display position (center line position) of each symbol 29 is shifted with respect to the reference winning line 5, The error is, as a maximum value when viewed strictly, only a small value range due to the one pulse displacement amount. For this reason, this small error can be substantially set as a tolerance range, and there is no problem even if it is regarded as a stop display at the center line position of the symbol with respect to the winning line 5. Therefore, when the symbol belt 28 is mounted, the symbol belt 28 can be freely mounted without being restricted by the selection of the position of the symbol with respect to the main pulley 19 or the setting of the reference, and the trouble and trouble can be avoided. But pattern belt 2
8 can be rotated lightly. In addition, when the detection position of the detection means 31 is viewed, on the assumption that each symbol 29 is stopped and displayed with the center line position within the above-mentioned tolerance range with respect to the winning line 5, the position of the winning line 5 is determined. Can be set to a position based on 1 pulse displacement amount × set pulse number.

A basic input / output control system relating to the substantial display unit (three symbol units U) of the display device M is constituted by the control circuit device E which is schematically shown in a block diagram in FIG. 11 as an example. Have been. In this circuit device E, a winning determination unit 51, a random number data setting unit 52, a motor control unit 53 and a pulse generation unit 54, a counter unit 55 for each symbol display unit U, and a symbol detection unit 5
6 is a basic main control section, 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 in response to the start signal input”. ), And the symbol units U in the three rows shown can be subjected to the fluctuation / stop control processing in a predetermined order, time, and shift condition.

As a reference example, in the above-mentioned "symbol origin position confirmation control process", in the case where the symbol origin alignment in the three-row symbol unit U is displayed as "out of alignment", the winning determination unit 51 is turned on when the power is turned on. According to the response with the random number data setting unit 52, one “missing initial data” related to the stop symbol in each column is selected and held in the winning determination unit 51. Under this data condition, the drive control (pulse output) of the motor control unit 53 in response to the instruction from the winning determination unit 51
On the other hand, the three rows of motors 17 are sequentially driven to rotate the symbol belt 28, while the winning determination unit 51 suspends the symbol mark detection condition related to the detection stop symbol for each column.
Under this condition, the detection means 31 of each row, which has received the detection condition instruction from the winning determination section 51 after a set time, detects the reference mark 30 of the symbol belt 28 for each row, and starts the “missing initial data” from the point of time. When the corresponding mark at the predetermined position (including both marks 30 and 30a) is detected, the information is input to the winning determination unit 51 via the counter unit 55 and the symbol detection unit 56.

After a set time from the end of the mark detection, the symbol belt 28 is stopped together with the motors 17 in each row in accordance with the stop of the drive control (stop of the pulse output) from the motor control unit 53, and the detected mark is stopped. One symbol 29 is stopped and displayed on the winning line 5. In this result, the contents of the detection information of the detecting means 31 of each column are sequentially input to the counter unit 55 and the symbol detecting unit 56, and the detected symbol mark and the counter value corresponding thereto are detected.
(0-20) and the type 29 of the symbols 29 (A to U) are subjected to a comparison conversion process and the like. Confirmed and kept waiting. In this “confirmation control processing”, in addition to the above-described “out-of-initial data” processing method, a “time control data” processing method based on a temporal processing condition between the winning determination unit 51 and the motor control unit 53. Can also be suitably adopted.

On the other hand, the "symbol change stop control process" is performed in response to a start signal input generated during a pachinko game. That is, in response to one start input, the symbol belt 28 is rotated according to the sequential drive of the three rows of motors 17 by a pulse output transmitted from the motor control unit 53 based on an instruction from the winning determination unit 51, In the data setting unit 52, one for the stop symbol corresponding to the start input is set.
Two “sampling data” are selected. For this “sampling data”, all the marks 3 on the symbol belt 28 out of the total number of symbol combinations
The data is determined to be any one of the data for the loss and the hit for the information corresponding to the figure number counter value corresponding to 0, 30a, and is input to the prize determination unit 51 and temporarily held. Next, in response to the processing instruction of the winning determination unit 51, the detection unit 31 sets “ Based on the detection conditions determined by the "sampling data", for example, a 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 unit 51 via the counter unit 55 and the symbol detection unit 56.

After a set time from the end of the detection, the symbol belt 28 is stopped together with the motors 17 in each row in accordance with the stop of the pulse output from the motor control unit 53, and one symbol (hit) is detected with respect to the detected symbol mark 30a, for example. ) 29 is stopped and displayed on the pay line 5. At this time, the content of the mark detected by the detecting means 31 of each column is determined by any one of the marks 3 detected from the detection time of the reference mark 30 by the respective counter unit 55.
The counter value corresponding to the position of 0, 30a is detected in the range of “0 to 20” and input to the symbol detection unit 56, and the type of the symbol 29 (A to U) is determined from the counter value detected by the detection unit 56. ) Is detected and determined, and information is input to the winning determination unit 51. Based on this, the same determination unit 51 determines each stop symbol individually and entirely based on the "sampling data". As a result, the symbol combination on the winning line 5 is determined to be "hit" in the case of, for example, three rows of the same type of symbol match, and is otherwise determined to be "missing (including out-of-reach)".

In this control process, as another method, one "sampling data" extracted from the random number data setting section 52 is divided into either one of a predetermined hitting and a non-hitting one. A method in which the data is determined and the input processing is performed by dividing the data into the hit processing section and the departure processing section of the winning determination section 51 can also be suitably adopted. Incidentally, as an example of creation and setting of “sampling data” according to this control processing example, a sequence (random number) in which a hit processing number “number 1” and a departure processing number “number 2” are arranged in an appropriate order and circulated at a predetermined cycle. Table) is employed, and one "sampling data" within this sequence and having a hit or miss process number at the start input is extracted.

The symbol variable display device M according to the present embodiment as described above.
According to the symbol stop display example by the direct mark detection described above, according to the symbol belt 28 of the symbol unit U of each row.
However, even if any error occurs in the displacement amount corresponding to the number of basic pulses corresponding to each symbol frame, when the detection means 31 detects the predetermined detection mark 30, 30a, the symbol value is calculated from the counter value corresponding thereto. The symbol 29 can be accurately detected and interpreted, and after a predetermined time, the symbol 29 can be stopped and displayed on the pay line 5. For each combination of symbols stopped on the other pay lines (horizontal and vertical lines and diagonal lines) other than the reference pay line 5, the counter value of each symbol on the reference pay line 5 Accordingly, detection and determination are performed based on the calculation process based on the counter values of “+1 and −1” (the set number of pulses for one symbol). In addition, the speaker 57 and the display lamp 36 illustrated in FIG. 11 generate respective sound effects and display lights 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 frictional electrification (static electricity) of the rotating body of the rotation drive control mechanism 16 and the symbol belt 28 and dirt (dust) attached to the symbol belt 28 due to the electrification, these are preferably removed. The following configuration has been added as a countermeasure for such a situation.

First, a part of the rotating body of the mechanism 16, mainly the main pulley 19 and the slave pulley 20,
Conductive resin, for example, base resin mainly composed of polypropylene, conductive carbonaceous material kneaded and compounded composite conductive resin material, each required size (diameter, shaft length)

Using the adhesive surface 78 provided on the back surface of the base frame 76, the upper right side of the cover 35 of the lighting fixture 33 in each row (detection means 31
(The lower part of the belt), and the brush part 77 can directly contact the side edge part of the front side band part 28a on the back side of the belt, particularly the part where the detection marks 30, 30a are located. Has become. Thereby, in the continuous movement of the symbol belt 28, the brush portion 7 of the removing member 75
7 is always in contact with the position of the detection marks 30 and 30a so that the charge can be suitably removed (air discharge), the adhesion of dust due to the charge can be reduced, and the attached dust can be removed cleanly.

Therefore, in the design variable display device M of the present embodiment in which the above-described countermeasures against static elimination and dust removal are taken,
As an additional function and effect of the configuration relating to the main and sub pulleys 19 and 20 and the installation of the removing member 75, the antistatic of the symbol belt 28 and the detection marks 30, 30a can be prevented under the condition that the generation of static electricity can be prevented. Can prevent the position of
The detection marks 30, 30a can always be maintained in a normal detectable state even during long-term use. As a result, during the movement of the symbol belt 28, the detection marks 30,
The detection failure of the detection means 31 caused by the contamination of 30a can be eliminated beforehand, and long and proper mark detection can be achieved.
As a result, a precise symbol display and a combination game can be presented by performing accurate fluctuation / stop control of the symbol belt 28.

The cover 35 may be other than the cover 35, and can be directly attached to the set plate 11, for example. Further, a U-shaped mounting member that sandwiches the edge of the symbol belt 28 where the detection marks 30, 30a are formed with a required gap from both sides is disposed on the cover 35 or the set plate 11, and the inside of the mounting member is Alternatively, a removing member 75 may be attached to the belt 28 so as to be in contact with the design belt 28 so as to remove dust and remove charges from the belt 28. Further, a plurality of removal members 75 may be provided on the way of rotation of the symbol belt 28. In addition, the main pulley 19 and the slave pulley 20 may be formed of an appropriate resin having no conductivity, and the brush portion 77 of the removing member 75 does not have conductivity in the base cloth 76. Fibers planted can be used.
