123b is provided, and the positioning elongated holes 123a, 123
Mounting holes 124a and 124b are formed in the lower part of b, and locking projections 125 are formed in the upper parts of the positioning elongated holes 123a and 123b.
a and 125b are formed. Therefore, the engaging recesses 129a, 1a at the upper ends of the slide guide members 126a, 126b are formed.
29b is locked to the locking projections 125a and 125b, the mounting holes 12 below the slide guide members 126a and 126b.
8a and 128b are made to correspond to the mounting holes 124a and 124b, and screws are screwed into the slide guide member 1.
26a and 126b can be attached to the attachment bases 101a and 101b. The slide guide member 126
The springs 135a and 13 to be described later are provided at the bottom of the a and 126b.
Spring locking pins 130a, 130b for locking the lower end of 5b
Are formed so as to project.

A guide slot 127 is formed at the center of the slide guide members 126a and 126b attached as described above.
a, 127b are formed. And the guide slot 127
insertion protrusions 133a and 133b to be inserted into a and 127b
The sliding members 132a and 132b integrally formed with each other are vertically slid along the guide elongated holes 127a and 127b, and the tension pulley shaft 136 is stretched over the sliding members 132a and 132b. Sliding members 132a, 13
Spring locking pins 134a and 134b are provided at the lower end of 2b so as to project. The spring locking pins 134a and 134b and the spring locking pin 13 of the slide guide members 126a and 126b.
Springs 135a and 135b are interposed between the springs 0a and 130b. Therefore, the sliding members 132a and 132b are
The springs 135a and 135b are always urged upward.

The tension pulley 136, which is rotatably supported by the tension pulley shaft 131, has bearing bearing members 137a, 137 in front of and behind the shaft cylinder 136a.
b is interposed, and the bearing bearing members 137a, 137
A tension pulley 136 is rotatably supported by a tension pulley shaft 131 via 7b. Further, as shown in FIG. 8 (A), the tension pulley 136 has belt guide protrusions 138 projecting from both ends of the outer periphery, and guides the rotating film belt 190 so as not to come off the pulley. Further, the tension pulley 136 has a dust removing groove 139 formed at the base of the belt guide convex portion 138, so that dust or dirt adhering to the film belt 190 or the like for a long period of time is attached to the end portion of the tension pulley 136. It tends to be collected, but it can be easily removed.

In the present embodiment, the outer peripheral shape of the tension pulley 136 is a drum-shaped crown curved surface 140b in which the diameter L2 of the central portion is smaller than the diameter L1 of the end portion as shown in FIG. 8B. Has been formed. The reason for this is that the drive pulley 143, which will be described later, has a drum-shaped crown curved surface and has a large diameter to increase the contact area so that the film belt 190 can be centered as much as possible and the contact force can be reliably rotated. The contact frictional force between the drive pulley 143 and the film belt 190 is relatively large. In this situation,
In order to reduce the frictional force between each of the pulleys 136, 141 and 143 and the film belt 190 as much as possible to obtain smooth rotation, the tension pulley 136 has the hourglass-shaped crown curved surface 140b. For the same reason, the driven pulley 141, which will be described below, also has the hourglass-shaped crown curved surface 14.
You may make it have 0b. Of course, the tension pulley 136 and the driven pulley 141 may be a drum-shaped crown curved surface 140a in which the diameter L3 of the central portion is larger than the diameter L1 of the end portion as shown in FIG. 8C. In this case, it is considered that the frictional force increases to some extent.

The driven pulley 141 rotatably supported by the driven pulley shaft 103 has, as shown in FIG. 10, metallic dry bearing members 142a and 142b interposed at both ends of its shaft cylinder 141a. The driven pulley 141 is rotatably supported by the driven pulley shaft 103 via the dry bearing members 142a and 142b. The dry bearing members 142a and 142b have the same function as the dry bearing members 144a and 144b, which are the bearing members of the drive pulley 143, which will be described below, and thus the details will be described below.

As shown in FIG. 9, the drive pulley 143 rotatably supported by the drive pulley shaft 102 has a metal dry bearing member 1 at both ends of its shaft cylinder 143a.
44 a and 144 b are interposed, and the drive pulley 143 is rotatably supported by the drive pulley shaft 102 via the dry bearing members 144 a and 144 b. These dry bearings 144a and 144b are molded by powder metallurgy, and a large number of grooves 145 are formed on the inner peripheral surface that abuts the drive pulley shaft 102 to reduce frictional resistance and ensure smooth rotation. It has become a bearing.
Further, the gear portion 14 is provided on the outer periphery of one end of the drive pulley 143.
6 is integrally formed, and the gear portion 146 is fixed to the motor shaft 151 of the stepping motor 150.
6 is engaged with the stepping motor 15
The rotational force of 0 is transmitted to the drive pulley 143. In this way, by adopting the transmission method of gears, compared to other transmission methods (for example, belts and rubber discs), there is less deformation even after long-term use, and the area where slippage is awaited. Therefore, the drive pulley 143 can be stopped at an accurate position. Further, a silicone coating 147 is applied to the outer peripheral surface of the drive pulley 143. The silicon coating 147 is applied to increase the frictional force between the drive pulley 143 and the film belt 190.
The slipping amount of 0 is almost eliminated to ensure the reliable rotation of the film belt 190 by the stepping motor 150.

Next, the mounting structure of the stepping motor 150 for rotationally driving the drive pulley 143 will be described. This mounting is as described above, and the mounting piece of the mounting plate 152 of the stepping motor 150 is mounted on the motor. It is performed by fixing the piece 105 with a screw. When the stepping motor 150 is attached to the motor attachment piece 105, the stepping motor 150 is surrounded by the three pulleys 136, 141, 143. Further, the wiring 154 is extended from the stepping motor, and the connector 155 attached to the tip of the wiring 154 is the substrate 1 described below.
It is connected to the motor connection connector 164 of 60. Also,
The motor shaft 151 of the stepping motor 150 has a gear 156 that meshes with the gear portion 146 of the drive pulley 143.
Is stuck. This fixation is accurately performed by fitting the D-shaped fitting hole 157 formed in the center of the gear 156 to the motor shaft 151.

Next, the substrate 160 mounted inside the auxiliary side mounting base 101b will be described. Board 16
0 is constituted by a printed wiring board, and the board 16
0 to the mounting hole 161 formed on the upper part of the board mounting hole 1
The upper part is fixed by fastening with screws in correspondence with 20, and the lower part is fixed by engaging the engaging mounting hole 162 formed in the lower part with the board mounting hook 121. However, when the upper part is fixed with screws, the board 16
The lamp cover 166 for covering the fluorescent tube lamp 163 provided in No. 0 is also fixed together. That is, as shown in FIG.
The fluorescent tube lamp 163 that emits light from the rear surface is planted by the lamp wiring legs 171.
Fluorescent tube lamp 16 to reflect the light of the front part only
The lamp cover 166 covering the rear of the No. 3 is attached to the substrate 160. The mounting is performed by inserting and supporting the fluorescent tube lamp 163 into the lamp through hole 168 formed in the lamp cover 166 and the lamp holder 169, and then mounting holes 16 formed in the side portions of the lamp cover 166.
7 is made to correspond to the mounting hole 161 of the substrate 160, and a screw is inserted from the substrate mounting hole 120 and screwed to be mounted. Since the fluorescent tube lamp 163 inserted into the lamp cover 166 reaches only the middle of the lamp cover 166, only half of the film belt 190 is illuminated brightly. In order to eliminate such a defect, the reflective convex portion 1 is provided on the tip of the lamp cover 166.
70 is formed to diffusely reflect the light emitted from the fluorescent tube lamp 163 to illuminate the entire area of the film belt 190 brightly. When the board 160 is mounted on the auxiliary side mounting base 101b, the board mounting hole 120 and the solder surface contact preventing projection 122 are connected as described above.
An insulating space 172 is formed between the substrate 160 and the auxiliary-side mounting base 101b by. Further, on the board 160, as described above, the motor connector 164 for connecting the connector 155 of the wiring 154 of the stepping motor 150 and the collective connector 1 for connecting the motor / lamp connectors 74a to 74c.
And 65 are provided.

Next, the sensor substrate 180 mounted on the switch mounting piece 109 will be described. The sensor substrate 180 has a mounting recess 181 formed at one end thereof for engaging with the stopper 110, and the other end portion. A mounting hole 182 corresponding to the stop hole 111 is formed in the mounting hole 182, and the mounting recess 181 and the mounting hole 182 are mounted on the switch mounting piece 109 as described above. In addition, a pair of sensors 183 (hereinafter, referred to as sensor A) and 184 (hereinafter, referred to as sensor B) are mounted on the sensor substrate 180 at predetermined intervals, and the connector 1
Wiring 18 in which 85 is mounted and is connected to the connector 185
The other connector 187 of 6 is directly connected to the sensor connectors 73a to 73c.

As shown in FIG. 6, the sensors A and B are both light emitting elements 183a and 184a and light receiving elements 183b and 18.
4b are provided in parallel on the same side with respect to the film belt 190, and the light emitting elements 183a and 184a are provided.
Light receiving element 18 on which light (near infrared) emitted from
The detection signal is derived when the light is received by 3b and 184b. The detection signal is derived when the symbol position detection index 191 and the reference position detection index 192 formed on the film belt 190 have passed.

As described above, the mounting bases 101a, 101
Pulleys 136, 141, 1 rotatably provided between b
The film belt 190 wound around 43 is an endless belt made of an extremely thin synthetic resin, and a plurality of patterns as identification information is formed on the outer periphery of the band, so that each pattern corresponds to the pattern. A pattern position detection index 191 is formed outside one end of the film belt 190. The symbol position detection index 191 is formed of a reflective paint that efficiently reflects the light emitted from the light emitting elements 183a and 184a of the sensors A and B, and each symbol position detection index 19
1 is an interval in which both sensors A and B are not turned on at the same time,
To put it the other way around, the two sensors A and B are provided on the sensor substrate 180 at intervals slightly smaller than the interval at which the symbol position detection index 191 is formed. However, since one of the symbol position detection indexes 191 is formed as the reference position detection index 192 that is formed to be a little long, the reference position detection index 192 and the symbol position detection index 191 that are adjacent to each other are two. The sensors A and B are turned on at the same time. Therefore, the number of steps of the stepping motor 150 is reset every time the reference position detection index 192 is detected, and by counting each time, the number of supply steps to the stepping motor 150 is controlled to obtain a desired symbol. It can be stopped and controlled at the position. However, when controlling only by the number of supply steps to the stepping motor 150, when a slip occurs between the film belt 190 and the pulleys 136, 141, and 143, the pattern may be displaced from the desired position and the pattern may be displayed. So
The stop of the symbol is performed by the number of supply steps to the stepping motor 150 and the detection of the symbol position detection index 191. Since the slip phenomenon is unlikely to occur significantly, the symbol position detection index 191 does not have to be provided so as to correspond to all symbols, for example, every other symbol, 2
You may form every other. Further, the index may be an absorbing paint or an absorbing member to reflect the material of the belt.

Further, in the case of the illustrated embodiment, when the auxiliary side mounting base 101b is mounted on the reference side mounting base 101a, the film belt 190 is attached to the pulley 136 and the film belt 190.
Since it cannot be bridged between 141 and 143, the stepping motor 150, the sensor substrate 180, and the pulleys 136, 141, and 143 are mounted on the reference-side mounting base 101a.
With the film belt 190 attached,
After that, the auxiliary mounting base 10 to which the substrate 160 is mounted is attached.
It is necessary to assemble so that 1b is attached at a predetermined position. In this case, since many parts are accurately attached to the reference side attachment base 101a first, the assembling work can be easily performed. However, the spring 135b of the tension pulley 136 is attached to the slide guide member 126b.
It is not easy to insert the spring locking pin 130b into the spring locking pin 130b, and it must be carefully assembled.

The configuration of the rotary belt unit 100 of the rotary drum device 50 according to the embodiment has been described above in detail. The features of the rotary belt unit 100 according to the present embodiment are as follows. First, as the first feature, the drive pulley 143 and the driven pulley 1 in which the mounting positions of the sensors A and B as position detectors for detecting the pattern position detection index 191 of the film belt 190 do not change
41 is the point provided between them. For example, when the film belt 190 extends due to long-term use, the position of the tension pulley 136 changes as shown in FIG. In this case, the sensors A and B are connected to the driven pulley 1
41 and the tension pulley 136, a distance L2 between the sensors A and B and the film belt 190 is set.
Is shifted by Δ2, so the symbol position detection index 191
The detection position of will shift. For this reason, there is a drawback that the stop positions of the symbols at positions visible to the player are not aligned neatly on a predetermined position (on the hit line) and are displaced. Similarly, the sensors A and B are connected to the drive pulley 14
3 and the tension pulley 136,
The distance L3 between the sensors A and B and the film belt 190 is Δ
Since the position shifts by 3, the detection position of the symbol position detection index 191 is shifted accordingly. For this reason, there is a drawback that the stop positions of the symbols at positions visible to the player are not aligned neatly on a predetermined position (on the hit line) and are displaced. On the other hand, as in this embodiment, the sensor A,
Between the drive pulley 143 and the driven pulley 141 (the position of each pulley 1
When provided at a distance L4) between the center points of 43 and 141,
Since the distance L1 between the sensors A and B and the film belt 190 does not shift, it is possible to stop the design at an accurate position for a long period of time.

The pattern position detection index 191 is not formed by reflecting but is formed as a hole for transmitting light, and the light emitting elements 183a, 184 of the sensors A, B as position detectors.
a and the light receiving elements 183b and 184b are connected to the film belt 1
When the film belt 190 is extended when the film belt 190 is provided at a position opposed to 90, the extended film belt 190 causes the extended light emitting element 183a, as shown in a circle in FIG.
Since it is possible to predict that one of the light receiving elements 184a or the light receiving elements 183b and 184b will come into contact with the driving pulley 143, the sensors A and B are installed at the drive pulley 143 also in this case.
Between the driven pulley 141 and the driven pulley 141.

Next, as a second feature, a plurality of pulleys 136, 14 for rotatably supporting the film belt 190 are provided.
Pulley shafts 102, 10 for rotatably supporting the shafts 1, 143
3, 131 is provided so as to be sandwiched by a pair of mounting bases 101a and 101b, and one reference side mounting base 101a has a drive pulley shaft 102 that rotatably supports a drive pulley 143 and a driven pulley. Driven pulley shaft 103 for rotatably supporting 141, and tension pulley 1
The gap holding shaft 104 located below 36 is fixed by caulking, and the switch mounting piece 109 for mounting the sensor substrate 180 having the sensors 183 and 184 as position detectors, which will be described later, and the stepping motor 1
A motor mounting piece 105 for mounting 50 is integrally formed, and the other auxiliary side mounting base 101b has the drive pulley shaft 102, the driven pulley shaft 103, and the spacing shaft 104.
It is a point where one end of is fixed with a screw.

That is, since the pulley shafts 102, 103, 131 are supported on both sides by the pair of mounting bases 101a, 101b, the pulley shafts 102, 103, 131 can be used for a long period of time as compared with the case where they are supported by one mounting base. Film belt 19
0 can be accurately driven, and the mounting positions of the pulleys 143, 141 and 136, which are required to maintain accuracy as a function of the rotary belt unit 100, the mounting position of the stepping motor 150 as a drive source, Also, the mounting positions of the sensors 183 and 184 as position detectors for determining the pattern of the film belt 190 are 1 respectively.
Since the two reference-side mounting bases 101a are used as the reference, they can be freely installed in any one of the left and right mounting bases 101a and 101b without any entanglement. The lack of accuracy due to defects can be eliminated. Further, by using one of the mounting bases 101a as a reference, the assembling work can be simplified.

As the third feature, the film belt 1
Among the plurality of pulleys 136, 141, 143 with which 90 abuts, the diameter of the drive pulley 143 driven by the stepping motor 150 is formed to be larger than the diameters of the other pulleys 136, 141, and the contact area with the film belt 190 is increased. Is a big thing. As a result, the friction between the film belt 190 and the drive pulley 143 is increased to suppress the slip phenomenon as much as possible, and the accurate film belt 1
The rotation control of 90 can be realized. Particularly, when the drive pulley 143 is arranged at the acute angle portion of the right-angled isosceles triangle as in the present embodiment, the contact area can be further increased, and the above effect can be further enhanced. it can. Also, the above effect can be enhanced by providing the driving pulley 143 with a silicon coating 147 (which may be a coating of another material) for improving the frictional resistance value or by winding an annular member such as rubber (which may be another material). Can be made. If the diameter of the drive pulley 143 is larger than the diameters of the other pulleys, the drive pulley 143 does not necessarily have to be at the acute angle position, and may be, for example, the driven pulley 141 position. Further, as a characteristic of the pulleys, by making the outer peripheral surface shape of any one of the pulleys a drum-shaped crown curved surface 140a, the film belt 190 comes closer to the center when the film belt 190 is rotated, so that the pulley is always supported. It will rotate along the correct orbit passing through the center. In order to obtain the same effect, belt guide protrusions 138 may be formed on the outer circumferences of both ends of any one of the pulleys. Further, by combining the pulley having the drum-shaped crown curved surface 140a and the pulley having the drum-shaped crown curved surface 140b as the outer peripheral surface shape of the plurality of pulleys, the excessive frictional force is suppressed as much as possible, and the film belt 190 is smooth. It can also be rotated.

As a fourth characteristic, as shown in FIG. 6, the tension pulley 136 is biased in a direction coinciding with the bisector of the apex. As a result, since the film belt 190 can be smoothly rotated with substantially the same force in both forward and reverse rotation directions, a more complicated rotation operation of the film belt 190 can be realized.

As a fifth feature, as shown in FIG. 6, the inside of a polygon (triangle in the case of the embodiment) surrounded by a plurality of pulleys 136, 141 and 143, which is a stepping motor 150 as a drive source, is used. Since the stepping motor 150 having a relatively large size can be easily used, the cost can be reduced, and the degree of freedom in designing can be greatly improved. That is, the stepping motor 150 as a drive source is connected to the drive pulley 1
Although a method of storing the stepping motor 150 in the interior of the stepping motor 43 is conceivable, in this case, since the stepping motor 150 needs to be downsized, the cost increases accordingly and the size of the stepping motor 150 causes the driving pulley 150 to be driven. Since the size of 143, the size of other pulleys, and the width and length of the film belt 190 are restricted, the degree of freedom in design is reduced.

In the above embodiment, the pattern position detection index 191 is formed at the end of the outer surface of the film belt 190, so that the sensors A and B as position detectors are arranged outside the film belt 190. I showed what I did,
As shown in FIG. 13, the sensors A and B are connected to the film belt 1
You may arrange | position inside 90. In this case, since the symbol position detection index 191 is formed at the end portion of the inner side surface of the film belt 190, each pulley 136, 14
As shown in FIG. 14, it is desirable to form an index avoiding recess 148 on the index forming side of 1, 143. As a result, the symbol position detection index 191 can be reliably detected without wear even after long-term use. In addition,
An advantage of forming the pattern position detection index 191 on the inner surface of the film belt 190 is that it is not restricted by the identification information (pattern) formed on the outer surface of the film belt 190. In addition, in the embodiment shown in FIG. 13, a liquid crystal display 195 (CR
T or a display device for displaying a still image may be provided, a half mirror 196 may be provided in place of the transparent plate 33, and the image projected on the liquid crystal display device 195 and the design of the film belt 190 are combined to be visually recognized by the player. I am able to do it.

Further, in the above-mentioned embodiment, the stepping motor 150 is installed at a position surrounded by a polygon formed by a plurality of pulleys.
As shown in FIG. 5, the stepping motor 150 is built in the drive pulley 143, and the stepping motor 150 is directly connected.
The drive pulley 143 may be connected to the motor shaft of. In this case, there is an advantage in that the device having the above-mentioned drawbacks can be simplified. In the embodiment shown in FIG. 15, the sensors A and B are of transmissive type.

The game operation of the game device provided on the game board 1 such as the variable display device 30 and the variable winning ball device 6 described above is controlled by the control circuit shown in FIG.
FIG. 16 is a block diagram of a control circuit that controls a game operation. Briefly explaining this, MPU, RO
It is controlled by a basic circuit 200 including M, RAM and input / output circuits. Then, the basic circuit 200 is the input circuit 2
The detection signals from the winning ball detector 11, the specific ball detector 10, the starting winning ball detector 5, and the plurality of sensors 183 and 184 are input via 04, and the address decoding circuit 205

On the other hand, the basic circuit 200 supplies control signals to the following devices and circuits. That is, the sound circuit 208
An audio signal is given to the speaker via the, and a drive signal is given from the basic circuit 200 to the big hit information circuit 209 which outputs the big hit information signal to the outside. In addition, a plurality of drum motors 150A-1

A display control signal is given to the display LED 12 and the decoration LED 40, and a drive signal is sent to the fluorescent lamp 163, the decoration lamp 19, and the opening / closing plate solenoid 9 via the lamp / solenoid circuit 203. Electric power having various voltages is supplied from the power supply circuit 210 to the above-described devices and circuits.

An example of the operation controlled by the above game control circuit will be described with reference to the flow charts of FIGS. 17 to 23. FIG. 17 is a flowchart showing a main routine executed by a reset signal which is periodically input, FIG. 18 is a flowchart of a pattern sensor check process executed by an interrupt signal, and FIG. 19 is an interrupt. FIG. 20 is a flowchart of a start winning a prize check process executed by a signal, and FIG. 20 shows steps 310 to 33 in FIG. 18.
It is a flowchart which shows the detailed subroutine of the process of 0,
FIG. 21 shows steps 130, 140, 150 of FIG.
FIG. 22 is a flowchart showing a detailed subroutine of each processing of 170, and FIGS. 22 and 23 are flowcharts showing a detailed subroutine of the processing of step 180 of FIG.

First, in FIG. 17, it is determined in step 10 whether or not the number of starting memories is "0". If it is "0", the process returns to the original state, and if it is not "0", the starting memory is stored in step 20. The random number value stored in the random number value storage area corresponding to the number 1 is read out, and then, in step 30, 1 is subtracted from the starting memory number, and the random number value storage area is shifted downward. Furthermore, in step 40, it is determined whether or not the read random number value is a hit, and when it is determined that it is not a hit, the stop symbol is determined by extracting the stop symbol determining random number in step 50. The determined stop pattern is the reach condition (the film belt 190 which stops first and then in step 60).
It is determined whether or not the combination of the symbols displayed on is on any hit line), and when the reach condition is not satisfied, the routine proceeds to step 130, where the reach condition is satisfied. If yes, step 70
It is determined whether or not the jackpot condition is satisfied. If the big hit condition is satisfied, in step 80, the symbol corresponding to the value obtained by adding "1" to the medium stop symbol is set, and then the process proceeds to step 90 to extract the random number for determining the reach pattern, The type (variation mode) is determined. Also,
If the big hit condition is not satisfied in step 70,
The process proceeds to step 90 without executing the process of step 80. On the other hand, when it is determined that the random number value is the big hit in step 40, the big hit symbol determination random number is extracted in step 100, the kind of big hit symbol and the hit line are decided, and then the reach pattern is decided in step 110. Random number is extracted and the type of reach (variation mode) is determined,
In step 120, the jackpot flag is set.

After the above processing is completed, step 13
At 0, the varying operation of all the film belts 190A to 190C is started, and then at step 140, the varying operation of the left symbol is stopped, and at step 150, the varying operation of the right symbol is stopped. Then, when the two symbols are stopped, it is determined in step 160 whether or not the reach is reached. If the reach is not reached, the changing operation of the middle symbol is stopped in step 170, and if the reach is reached, the reach is performed in step 180. The fluctuation stop operation of the middle symbol in is executed. Then, after the change operation of the medium symbol is finished, it is determined in step 210 whether or not the big hit flag is set. If the big hit flag is not set, a deviation process is performed in step 220, and the big hit flag is set. If it is set, the big hit process (repeated opening of the variable winning ball device 6) is executed in step 230, the big hit flag is reset in step 240 after the end of the big hit process, the game operation ends, and the process returns to the beginning.

Next, the symbol sensor check processing of FIG. 18 will be described. In step 300, it is determined whether or not the symbol is changing. If not changing, the process is ended without executing the following processing, and if changing, step 310.
The left symbol sensor check process is performed in, the right symbol sensor check is performed in step 320, the middle symbol sensor check is performed in step 330, and the process ends. Step 31
The detailed processing of 0, 320, and 330 is shown in FIG. 20, which will be described later.

Next, the start winning check process of FIG. 19 will be described. In step 400, it is determined whether or not there is a start prize. If there is no start prize, the process ends without executing the following process. If there is a start prize, in step 410 whether or not the number of stored starts is "4". Is judged, and if it is "4", the processing is ended without executing the following processing, and if it is not "4", "1" is added to the starting memory number at step 420, and then, at step 430, the hit is lost. A random number for determination is extracted, the extracted random number is stored in a random value storage area corresponding to the number of starting memories, and the process ends.

Steps 310, 320 and 330 described above
The detailed processing of will be described with reference to FIG. First, the left symbol sensor check processing of step 310 will be described with reference to FIG.
Then, it is determined whether or not the sensor A of the left symbol (rotating belt unit 100A) is turned on. If it is not turned on, the process is ended without executing the following process, and if it is turned on, In step 312, it is determined whether or not it is the timing when the left symbol sensor B is turned on. When it is determined that it is the timing when the sensor B is turned on, it means that both the sensors A and B are turned on at the same time, which means that the reference position detection index 192 is detected. The value of the current symbol is set to "0" (meaning the symbol for resetting the step number of the stepping motor 150 to 0), and the process is ended. On the other hand, when it is determined in step 312 that the sensor B is not the ON timing, it is determined that the normal symbol position detection index 191 is detected by the sensor A, and in step 314, "1" is added to the value of the left current symbol, and thereafter. In step 315, it is determined whether or not the value of the left current symbol is "21". In this case, since the number of symbols formed on the film belt 190A is 20, it is not possible for the value of the left present symbol to be "21" in the normal case, and the process of step 313 is performed before that. Be seen. Then,
If the value of the current symbol on the left is not "21", the process ends,
If "21", the left symbol error process is executed in step 316 and the state as it is is held.

Steps 321 to 326 of the right symbol sensor check process shown in FIG.
To 316 respectively, the description thereof will be omitted. Therefore, the medium symbol sensor check will be described next with reference to FIG. In step 331, it is determined whether or not the sensor A of the middle pattern (rotary belt unit 100B) is turned on, and if it is not turned on, the following process is not executed and the process is turned on.
If it is the timing, it is determined in step 332 whether it is the timing when the middle symbol sensor B is turned on.
When it is determined that it is the timing when the sensor B is turned on, it means that both the sensors A and B are turned on at the same time, which means that the reference position detection index 192 is detected. The value of the current symbol is set to "0" and the process ends. On the other hand, when it is determined that the sensor B is not the ON timing in step 332, it is determined in step 334 whether or not the motor is in reverse rotation. If not, the normal symbol position detection index 1
Assuming that 91 is detected by the sensor A, step 33
In step 5, "1" is added to the value of the medium-current symbol, and then in step 336, it is determined whether or not the value of the medium-current symbol is "21". In this case, since the number of symbols formed on the film belt 190B is 20, the value of the medium current symbol is "2".
There is no normal case where the value becomes "1", and the processing of step 333 is performed before that. Then, if the value of the left current symbol is not "21", the process is terminated and "2"
If it is "1", the left symbol error is processed in step 337 and the state is maintained as it is. Further, when it is determined that the motor is rotating in the reverse direction in step 334, it is determined in step 338 whether or not the value of the medium current symbol is "0", and if it is not "0", in step 339. Subtract "1" from the value of the current symbol, if "0",
The value of the middle-current symbol is set to "20" and the process ends.
The reverse rotation of the motor occurs in the state of reach mode 4 described later.

Next, step 13 of the main routine.
Detailed processing of 0, 140, 150, 170 is shown in FIG.
This will be described with reference to FIG. First, referring to FIG. 21 (A), the overall symbol variation process of step 130 will be described. In step 131, all the motors are activated and accelerated, and then in step 132, the acceleration state is changed to the constant speed state, At 133, the operation in the constant speed state is performed until the basic time (however, the basic time differs depending on the left symbol, the right symbol, and the middle symbol), and the process is ended.

In the left symbol stop process shown in FIG. 21 (B), the constant speed state of the middle and right motors is maintained at step 141, only the left motor is decelerated at step 142, and the left stop symbol at step 143. Wait until they match, and when they match, the left motor is stopped in step 144, and the process ends. In addition, the right symbol stop processing shown in FIG. 21 (C) is almost the same, the constant speed state of the middle motor is maintained in step 151, only the right motor is decelerated in step 152, and the right stop symbol is matched in step 153. Waits until, and when they match, the right motor is stopped in step 154, and the process ends. Further, the middle symbol stop processing shown in FIG. 21D is almost the same, only the middle motor is decelerated in step 171, waits until it matches the middle stop symbol in step 172, and when they match, the middle in step 173. The motor is stopped and the process ends.

Next, the detailed processing of step 180 of the main routine will be described with reference to FIGS. In step 181, the middle motor is decelerated, and in step 182, the type of reach pattern is selected. When the reach pattern 1 is selected, the medium motor is changed to a low speed rotation in step 183, the state is performed until the reach basic time in step 184 elapses, and the basic time elapses in step 185 and the intermediate stop symbol is displayed. Wait until they match,
When they match, the medium motor is stopped in step 186, and the process ends. When the reach pattern 2 is selected, the medium motor is changed to low speed rotation in step 187, and the state is maintained until the reach basic time in step 188 elapses, and then the medium motor is changed to ultra low speed rotation in step 189. Then, in step 190, the process waits until it matches the middle stop symbol, and when they match, the middle motor is stopped in step 191 and the process ends. When the reach pattern 3 is selected, the middle motor is changed to the low speed rotation in step 192, and the state is maintained until the reach reach basic time of step 193 elapses. Then, in step 194, the middle motor is once stopped and the step is performed. Wait for 195 hours (for example,
0.5 seconds), the middle motor is restarted in step 196, changed to low speed rotation again in step 197, waits until it matches the middle stop symbol in step 198, and when they match, the middle motor in step 199. To stop the process. When the reach pattern 4 is selected, the middle motor is changed to a low speed rotation in step 200, and the state is performed until the reach basic time in step 201 elapses, and the basic time elapses and one more than the intermediate stop symbol. When it is determined in step 202 that only the design has been rotated excessively, the intermediate motor is once stopped in step 203, and after waiting for the time of step 204 (for example, 0.5 seconds), step 205
In, the middle motor is restarted in the reverse direction to change to low speed rotation, and in step 206, the middle motor is stopped until it matches, and in step 207, the middle motor is stopped and the process ends.

[0069]

As is apparent from the above description, in the present invention, the belt type variable display device includes a driving rotary member driven by a motor, a driven rotary member, and a tension applying rotary member for applying tension. Since the diameter of the drive rotor is made larger than the diameter of the other rotors while the belt is hung between the rotors, the frictional force between the drive rotor and the belt is reduced. Since it can be made larger than the frictional force between the belt and the belt, the slip phenomenon of the belt can be suppressed and the identification information can be stopped at an accurate position.
