Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slot machine, and more particularly, it is possible to accurately detect the rotating condition of a rotating reel (design) in the slot machine and the position when the rotation is stopped, and at the same time, to cause a defect due to external factors And a slot machine capable of detecting a malfunction of the slot machine.

[0002]

2. Description of the Related Art Conventionally, a stepping motor has been generally used as a drive means for rotating reels in a slot machine. Since this stepping motor makes an equiangular rotational motion each time a drive pulse is supplied, the rotational position of the stepping motor can be obtained by counting the number of drive pulses supplied by the drive control side with a counter.

In practice, however, the number of drive pulses supplied to the stepping motor and the actual amount of rotation of the stepping motor are affected by defects in the drive system such as the motor connector and the components of the reel frame or the electric system. There may occur a phenomenon that the correspondence is displaced. As a result, when the rotating reel is stopped, the stop position of the rotating reel, that is, the symbol on the pay line when stopped, is shifted or a predetermined symbol (according to a random number generated by a random number generator (not shown) etc.) The pattern determined by the internal lottery) may have been different.

In order to deal with such a problem, a light-shielding piece is provided on the outer circumference of each rotating reel as a reference point, and the light-shielding piece is detected and reset by a photosensor each time the rotating reel makes one rotation. The technique of generating pulses has been used. FIG. 9 is a configuration diagram showing a slot machine including a conventional rotary reel with a light shielding piece. In FIG. 9, this slot machine includes a rotary reel 910 with a light blocking piece,
Drive unit 900, light-shielding piece detection unit 970, drive pulse counting unit 960, and control unit 930 having a pattern determination unit 934.
And a storage unit 940.

Here, the rotary reel 910 with the light shielding piece is
The reel wheel and a reel band attached to the outer circumference of the reel wheel are provided, and a light shielding piece is provided on a part of the outer circumference of the reel wheel. In addition, the drive unit 900
Is realized by a stepping motor or the like and rotationally drives the rotary reel 910 with the light shielding piece based on the drive pulse supplied from the control unit 930. The light-shielding piece detection unit 970 is realized by a photosensor or the like, and detects the passing light-shielding piece and outputs a reset pulse when the rotating reel 910 with the light-shielding piece is rotating. The drive pulse counting unit 960 is realized by a counter or the like, cumulatively counts the drive pulses supplied from the control unit 930 to the driving unit 900, and cumulatively counts by the reset pulse supplied from the light shielding piece detection unit 970. The cumulative pulse count value is reset.

The storage unit 940 is realized by a volatile and non-volatile semiconductor memory or the like, and the drive pulse counting unit 9
A second symbol table (not shown) in which the cumulative pulse count value counted by 60 and the symbol are associated with each other is stored. In addition, the symbol determination unit 934, the drive pulse counting unit 9
By referring to the second symbol table stored in the storage unit 940 based on the cumulative pulse count value of 60, the symbols on the pay line when the rotation of the light-shielding piece-equipped rotating reel 910 is stopped are determined. Further, the control unit 930 controls the CP
The driving unit 900 and the storage unit 940 are realized by U or the like.
The symbol determination unit 934 is realized by a program executed on the control unit 930 (CPU or the like).

In the conventional slot machine having such components, the number of drive pulses supplied to the stepping motor and the actual amount of rotation of the stepping motor are caused by a defect in the drive operation due to the drive system and components. Even if the correspondence relationship is deviated, the drive pulse counting unit 960 resets the cumulative pulse count value counted by the reset pulse by the light shielding piece every time the rotating reel 910 makes one rotation, so that it is supplied to the stepping motor. The device having the correspondence relationship between the number of generated drive pulses and the actual rotation amount of the stepping motor is reset.

[0008]

However, in the conventional slot machine described above, the number of drive pulses supplied to the stepping motor and the actual rotation of the stepping motor due to a defect in the drive operation due to the drive system and components. If the rotating reel 910 driven by the stepping motor does not make at least one rotation when a phenomenon in which the correspondence with the amount is deviated occurs, the reset pulse causes the accumulated pulse count value of the driving pulse counting unit 960 and the rotating reel 910 to rotate. Since the difference in the correspondence relationship with the rotation position of the rotary reel 9 is not set, the control unit side sets the rotation reel 9
In some cases, the rotation status of 10 (the symbol) and the stop position when the rotary reel 910 is stopped are not accurately grasped.

In the conventional slot machine, the drive pulse supplied to the drive unit 900 is converted into the drive pulse counting unit 96.
The configuration is such that the drive pulse counting unit 960 keeps counting the drive pulses even if a defect due to an external factor (for example, a mischief or a cheating by a player) occurs due to the configuration of counting by 0. Since the symbol determination unit 934 determines the symbol based on the cumulative pulse count value, the control unit cannot detect a defect due to such an external factor.

The present invention has been made in view of the above-mentioned conventional circumstances, and it is possible to accurately detect the rotation state of a rotating reel (design) and a position when the rotation is stopped in the slot machine, and at the same time, externally. It is an object of the present invention to provide a slot machine capable of detecting a defect due to a factor or an operation defect in the slot machine.

Claims 1, 2, 3, 4, 5, 6, of the present invention
In the slot machines according to 7, 8, and 9, the rotating reel is rotationally driven by the driving means, and the information reading means holds the code information corresponding to the symbol on the rotating reel. The bar code is optically read, and the symbol recognition means recognizes the symbol based on the code information read by the information reading means.

In this way, the pattern drawn on the outer peripheral surface of the rotating reel corresponding to the code information is recognized based on the code information read by the information reading means.
During rotation of the rotary reel 310 or when the rotation of the rotary reel 310 is stopped, it is possible to always accurately detect a symbol at a predetermined position of the slot machine, for example, a symbol on a pay line.

Further, in particular, in the slot machine according to the second aspect, it is preferable that the slot machine is provided with a storage means for storing a symbol table which associates the code information read by the information reading means with the symbol.

Further, in the slot machine according to the third aspect of the present invention, the first abnormality determining means determines whether or not there is an abnormality based on the recognition result of the symbol recognizing means, and the notifying means determines that the abnormality has occurred. When it is determined, the fact is notified.

For example, if the rotational speed of the rotating reel (the number of symbols per unit time) is detected based on the symbol recognized by the symbol recognizing means, and it is different from the predetermined rotational speed of the rotating reel, the first The abnormality determination means determines that the slot machine is abnormal, and the notification means notifies the manager / maintenance manager of the slot machine to that effect, whereby the rotation reel is displaced or forced due to a defect caused by an external factor by the player. It is possible to detect a stop of the rotating reel, an operation failure due to a drive system such as a motor connector, an operation failure due to a reel frame or a component of an electric system even before the rotation reel is stopped.

Further, for example, when the design recognized by the design recognizing means and the design preliminarily determined by the internal lottery are different when the rotation of the rotating reel is stopped, it is determined that the first abnormality determining means is abnormal, By notifying the manager / maintenance manager of the slot machine by the notification means, the rotation reel is displaced or forcedly stopped due to a defect caused by an external factor, or the motor connector is driven. It is possible to detect an operation failure due to the system, an operation failure due to a reel frame or the like, or a component of the electric system.

Further, in the slot machine according to the fourth aspect, the number of drive pulses input to the drive means is counted by the drive pulse counting means, but the base point detecting means corresponds to a specific symbol on the outer peripheral surface of the rotating reel. When the base point provided additionally is detected and the reset base point signal is input, the cumulatively counted number of drive pulses is reset. on the other hand,
In the symbol determining means, the symbol is determined based on the number of drive pulses cumulatively counted by the driving pulse counting means, and in the second abnormality determining means, the symbol recognized by the symbol recognizing means and the symbol determined by the symbol determining means. When it is determined to be abnormal by comparing the above, the notifying means notifies that effect.

In this way, the second abnormality determining means compares the symbol recognized by the symbol recognizing means with the symbol determined by the symbol determining means, and when it is detected that they are different, it is determined to be abnormal. However, the notification means notifies the manager / maintenance manager of the slot machine to that effect.Therefore, the rotating reel is displaced or forcedly stops due to a defect caused by an external factor, or the motor connector or the like is stopped. It is possible to detect an operation failure due to the drive system, an operation failure due to a reel frame or the like, or a component of the electric system.

Further, in the slot machine according to the fifth aspect, the rotation speed detecting means detects the rotation speed of the rotating reel based on the read signal from the information reading means, and based on the detection result of the rotation speed detecting means. The presence / absence of an abnormality is determined by the third abnormality determining means, and when the third abnormality determining means determines that there is an abnormality, the notifying means notifies that effect.

For example, the rotation speed of the rotating reel is obtained by detecting the bar code delimiter from the read signal of the information reading means and counting the number of bar codes detected per unit time, and in the third abnormality judging means. , For example, when it is determined that the rotation speed of the rotating reel is disturbed or the rotating reel is different from a predetermined rotation speed, the notification means notifies the manager / maintenance manager of the slot machine to that effect, The rotating reel is misaligned due to external factors, forcibly stops the rotating reel, malfunctions due to the drive system such as the motor connector, malfunctions due to the reel frame or electrical system components, etc. Can be detected even before the stop.
Further, since the abnormality determination is performed based on the rotation speed of the rotating reel, the bar code reading resolution of the information reading means can be suppressed to a low level when the symbol recognition during rotation is unnecessary.
As a result, the device cost can be reduced.

Further, particularly, in the slot machine according to the sixth aspect, it is desirable that the bar code is printed in correspondence with only the highly important design in the design. As a result, the number of barcodes can be reduced and the cost of the device can be reduced compared to the case of printing barcodes corresponding to all the patterns drawn on the rotating reel.

Further, in the slot machine according to the seventh aspect, it is desirable that the bar code has ancillary information such as model information, game type information or reel arrangement information in addition to the code information corresponding to the symbol. As a result, when the rotary reel is rotated or stopped, the information reading unit reads the type information of the slot machine, the game type information performed in the slot machine, or the arrangement information of the rotary reel attached to the slot machine. It is possible to prevent incorrect installation of the rotating reel in the manufacturing process, and also possible to prevent incorrect installation when changing the model or performing maintenance at the store in the management stage.

Further, in the slot machine according to the eighth aspect, it is preferable that the bar code is arranged so that the reading direction of the information reading means is parallel or orthogonal to the rotation direction of the rotating reel.

Further, in the slot machine according to the ninth aspect, when the bar code is arranged so that the reading direction by the information reading means is orthogonal to the rotation direction of the rotating reel, the bar code is read by the information reading means. It is desirable to make the length readable. In this way, by increasing the length of the bar of the barcode so that the barcode can be read by the information reading unit, the barcode can be reliably read by the information reading unit.

[First Embodiment] FIG. 3 shows a first embodiment of the present invention.
FIG. 3 is a configuration diagram showing a slot machine according to the embodiment of FIG.
In FIG. 3, the slot machine of this embodiment includes a drive unit 300, a rotating reel 310, an information reading unit 320, and
The control unit 330 including the symbol recognition unit 332 and the first abnormality determination unit 334, the storage unit 340, and the notification unit 350 are configured.

First, the rotating reel 310, the drive section 300 and the information reading section 320 will be described with reference to FIGS. 4 and 5. FIG. 4 is a perspective view showing a main part on the rotating reel side. Further, FIG. 5 is a development view of the rotary reel 310, FIG. 5A corresponds to an outer peripheral surface on which various symbols are drawn, and FIGS. 5B, 5C and 5D correspond to various symbols. Each of the back sides is printed with a barcode. It should be noted that in FIG. 7B, the barcode is printed such that the reading direction of the barcode is parallel to the rotation direction of the rotary reel 310, and in FIG. The bar code is printed so that the bar code reading direction is orthogonal to each other. In FIG. 7D, the bar code reading direction is orthogonal to the rotation direction of the rotary reel 310, and the bar length of the bar code is Is printed with a long barcode in the vertical direction (the rotation direction of the rotary reel 310).

First, the drive unit 300 drives the rotary reel 310 to rotate based on the drive pulse supplied from the control unit 330, and is realized by including a stepping motor 300a as shown in FIG. The rotary reel 310 includes a reel wheel 310a and a reel band 310b attached to the outer periphery of the reel wheel 310a, and the reel wheel 310a is fixed to the drive shaft 300b of the stepping motor 300a. .

Here, referring to FIG. 5, the rotating reel 31
The 0 reel band 310b will be described in detail. Figure 5
As shown in (a), various symbols constituting the winning combination shown in FIG. 2 are drawn on the surface (outer peripheral surface) of the reel band 310b, and on the back surface (inner peripheral surface) of the reel band 310b, As shown in FIG. 5B, the barcodes corresponding to the symbols drawn on the surface of the reel band 310b are printed such that the reading direction of the barcode is parallel to the rotation direction of the rotary reel 310. Has been done.

As shown in FIG. 5C, the barcode printed on the rotary reel 310 may be arranged such that the reading direction of the barcode is orthogonal to the rotation direction of the rotary reel 310. Good. At this time, since the barcode reading direction is orthogonal to the rotation direction of the rotary reel 310, the barcode reading direction by the information reading unit 320 is an oblique direction while the rotary reel 310 is rotating.
However, when the diameter of the rotating reel 310 is larger than normal, the linear velocity on the outer periphery of the rotating reel 310 becomes high, and therefore the barcode shown in FIG.
May not be read by. Therefore,
As shown in (d), the barcode is arranged so that the reading direction of the barcode by the information reading section 320 is orthogonal to the rotation direction of the rotary reel 310, and the bar length of the barcode is adjusted in the vertical direction. By increasing the length in the (rotational direction of the rotating reel 310), the barcode can be sufficiently read in the oblique direction by the information reading unit 320 even when the diameter of the rotating reel 310 is larger than usual. Also, FIG.
In (b), each bar code printed on the back surface of the reel band 310b is separated by a white background having a sufficient length, corresponding to each design drawn on the front surface of the reel band 310b. The length of the white background may be any length as long as the information reading unit 320 can recognize the division of the barcode, and the resolution of the information reading unit 320 can be further increased by increasing the size of the entire barcode. Is. Further, instead of the white background, blank information indicating a bar code delimiter may be inserted and printed.

The code information of the bar code printed on the back surface of the reel band 310b has a reel band 310b in addition to the pattern information representing the respective patterns drawn on the front surface of the reel band 310b. Spinning reel 310
The model information indicating the model number of the slot machine to which is attached, the game type information indicating the type of game played in the slot machine having the reel band 310b attached, and the rotary reel 310 having the reel band 310b are, for example, It includes reel array information indicating which array of the first to third rotating reels is mounted.

Further, in this embodiment, the reel band 310 is used.
Although the bar code is printed for all the patterns drawn on the surface of b, only the bar code corresponding to the “highly important pattern” may be printed. Here, the “highly important symbol” is, for example, a symbol constituting the winning combination shown in FIG. 2, and in particular, a symbol “7” or the like related to a high payout. In the present embodiment, a one-dimensional bar code is described as an example, but a two-dimensional bar code capable of recording about 1 kbyte of information may be used.

Next, the information reading section 320 is realized by a bar code reader 320a or the like (see FIG. 4), and the rotary reel 3 is used.
By irradiating the bar code printed on the back surface of the rotating reel 310 with light and receiving the reflected light from the bar code when the rotating reel 10 is rotated or stopped, the object to be read is rotated while the rotating reel 310 is rotating. Each bar code passing through the position is read, and when the rotation of the rotary reel 310 is stopped, the bar code at the read target position is read. The detailed configuration and operation of the bar code reader 320a are well known, and thus the description thereof is omitted.

The reading target position is, for example, a symbol position on the pay line. Therefore, as shown in FIG. 4, the bar code reader 320a is provided inside the reel wheel 310a so that the position to be read by the bar code reader 320a becomes a symbol on the pay line when the rotary reel 310 is stopped. By the way, the bar code reader 320a is provided at an arbitrary position inside the reel wheel 310a so that the control section 330 can judge which symbol is on the pay line from the recognition result of the symbol recognition section 331. May be. Further, in this embodiment,
Although the bar code is printed on the back surface of the reel band 310b, the bar code may be printed anywhere as long as it is invisible to the player. For example, when the bar code is printed on the side surface of the reel wheel 310a, the bar code is printed. The code reader 320a reads the bar code printed on the side surface of the reel wheel 310a so as to read the barcode.
It will be provided outside 0a.

Next, the symbol recognition unit 332 and the first unit shown in FIG.
The abnormality determination unit 334, the control unit 330, the storage unit 340, and the notification unit 350 will be described. The control unit 330 performs arithmetic processing such as drive control of the rotating reel 310, various display controls, and game progress control, and is realized by a CPU or the like. Further, the symbol recognition unit 332 recognizes the symbol based on the read signal read by the information reading unit 320. Here, the read signal is a pulse signal that represents the barcode read by the information reading unit 320 in time series. In addition, the first abnormality determination unit 334
Is for determining the presence or absence of abnormality based on the recognition result of the symbol recognition unit 332. The symbol recognition unit 332 and the first abnormality determination unit 334 are realized by a program executed on the control unit 330 (CPU or the like).

The notifying unit 350 is realized by a speaker, a display panel, or the like, and when the first abnormality judging unit 334 judges that the abnormality has occurred, the notifying unit 350 notifies that effect by voice output or message output. The notification unit 350
May be installed on the side of an administrator who is distant from the slot machine (for example, a system console which is connected to each slot machine by a line to operate and manage). Further, the storage unit 340 is realized by a volatile and non-volatile semiconductor memory (RAM, ROM, EEPROM, flash memory) or the like, and a first symbol table (not shown) in which code information and symbols are associated one-to-one. ) Is stored.

Next, the processing operation in the slot machine of the present embodiment having the above components will be described.
First, when the rotation reel 310 rotates or stops rotating,
The information reading unit 320 reads the bar code printed on the back surface of the reel band 310b of the rotary reel 310, and based on the read signal from the information reading unit 320, the pattern recognition unit 332 performs code information (numerical information), for example, Obtain type information, game type information, and reel arrangement information. Then, the first abnormality determination unit 334 determines that the rotating reel 310 having the formal reel band 310b is not attached to the slot machine based on the model information, the game type information, and the reel arrangement information obtained by the symbol recognition unit 332. In this case, the notification unit 350 notifies the administrator of the error based on the command from the first abnormality determination unit 334.

While the rotating reel 310 is rotating at a constant speed,
The bar code printed on the back surface of the reel band 310b of the rotary reel 310 is continuously or periodically read by the information reading section 320, and the code is recognized by the pattern recognizing section 332 based on the read signal from the information reading section 320. The information is recognized, and the rotation speed of the rotary reel 310 is obtained based on the reading interval (the number of pieces of code information per unit time) of the code information. Then, when the first abnormality determination unit 334 detects the disturbance of the rotation speed of the rotation reel 310, or the rotation speed of the rotation reel 310 and the pattern recognition unit which are predetermined by the control unit 330 which controls the rotation drive of the drive unit 300. When it is detected that the rotation speed of the rotating reel 310 obtained by 332 is different, the first abnormality determination unit 334.
The notification section 350 notifies the administrator of the error based on the command from the.

Furthermore, when the rotation of the rotary reel 310 is stopped, the information reading section 320 reads the bar code corresponding to the symbol on the pay line, and the symbol recognizing section 332.
By referring to the first symbol table stored in the storage unit 340, the symbol on the pay line represented by the code information obtained based on the read signal from the information reading unit 320 is recognized. Then, the first abnormality determination unit 334 determines whether or not the symbol on the pay line recognized by the symbol recognition unit 332 is different from the symbol on the pay line predetermined by the internal lottery in the control unit 330. If different, the notification unit 35 is based on the command from the first abnormality determination unit 334.
An error is notified to the administrator by 0.

As described above, according to the slot machine of this embodiment, the drive unit 300 rotationally drives the rotary reel 310 having plural kinds of symbols drawn on the outer peripheral surface,
The information reading section 320 optically reads a bar code having code information corresponding to the symbol on the rotary reel 310, and the symbol recognizing section 332 recognizes the symbol based on the code information read by the information reading section 320. I am trying.

Thus, the information reading section 320 optically reads the bar code having the code information corresponding to the symbol, and the symbol recognizing section 332 causes the code information stored in the storage section 340 and the rotary reel 310 to be read. By referring to the first symbol table that associates the drawn symbol with the symbol, the symbol drawn on the outer peripheral surface of the rotary reel 310 is recognized based on the code information of the barcode read by the information reading section 320, and therefore the rotation is performed. During the rotation of the reel 310 or when the rotation of the rotating reel 310 is stopped, the symbol at a predetermined position of the slot machine, for example, the symbol on the pay line can always be accurately detected.

Further, the first abnormality judging section 334 judges whether or not there is an abnormality based on the recognition result of the symbol recognizing section 332.
When it is determined that there is an abnormality, the notification unit 350 notifies that effect. In this way, the first abnormality determination unit 334 determines whether or not there is an abnormality based on the recognition result of the symbol recognition unit 332. For example, when the rotating reel 310 rotates, the interval between the symbols recognized by the symbol recognition unit 332 ( If the rotation speed of the rotary reel 310 obtained based on the number of symbols per unit time) and the predetermined rotation speed of the rotary reel 310 are different, it is determined to be abnormal, and the rotation reel 310 At the time of rotation stop, the symbol stopped at a predetermined position of the slot machine recognized by the symbol recognition unit 332, that is, if the symbol on the pay line and the predetermined symbol are different, it is determined to be abnormal, The notification unit 350 notifies the manager / maintenance manager of the slot machine that these abnormalities have occurred, so that the spinning reel due to a defect or the like caused by an external factor. Shift or stop the forced rotation reels 310, or, operation trouble caused by the driving system such as a motor consolidated, it is possible to detect the malfunction due component reel frame, etc., or electrical system.

The bar code has additional information such as model information, game type information or reel arrangement information in addition to the code information corresponding to the pattern printed on the rotary reel 310, so that the bar code of the rotary reel 310 can be obtained. At the time of rotation or stop of rotation, the pattern recognition unit 332 causes the information reading unit 32 to operate.

Then, the rotation speed detecting unit 738 detects the rotation speed of the rotating reel 310 based on the cumulative number of barcodes counted by the barcode number counting unit 760, and the third abnormality determining unit 734 causes the rotation speed detecting unit 738 to detect. When it is determined that the detected rotation speed of the rotary reel 310 is different from the predetermined rotation speed of the rotary reel 310 by the storage unit 730, the notification unit 350 notifies the administrator of the error.

As described above, according to the slot machine of this embodiment, the barcode number counting section 760 allows
The number of barcodes is counted based on the read signal from the information reading unit 320, and the rotation speed detection unit 738 determines the rotation speed of the rotary reel 310 based on the cumulative number of barcodes counted by the barcode number counting unit 760. The third abnormality determining unit 734 determines whether or not there is an abnormality based on the detection result of the rotation speed detecting unit 738.
When the abnormality determination unit 734 determines that there is an abnormality, the notification unit 350 notifies that effect.

In this way, the bar code number counting section 760 counts the number of bar codes read based on the read signal from the information reading section 320, and the rotation speed detecting section 73.
8, the rotation speed of the rotating reel 310 (the number of barcodes per unit time) is detected, and in the third abnormality determination unit 734, for example, the rotation speed of the rotating reel 310 is disturbed or the rotating reel 310 is predetermined. When it is determined that the rotation speed is different from the rotation speed, the notification unit 350 notifies the manager / maintenance manager of the slot machine to that effect. Therefore, the rotation reel shift or the forced rotation reel 310 due to a defect caused by an external factor or the like. Or the operation failure due to the drive system such as the motor connector, the operation failure due to the reel frame or the components of the electric system, and the like can be detected before the rotation reel 310 is stopped.

Further, the information reading section 320 optically reads the bar code having the code information corresponding to the pattern printed on the rotary reel 310, and the pattern recognizing section 732 reads the code information read by the information reading section 320. The pattern is recognized based on. In this way, the pattern recognition unit 7
By 32, the code information stored in the storage unit 340 and the design drawn on the rotating reel 310 are associated with each other.
Since the pattern drawn on the outer peripheral surface of the rotating reel 310 corresponding to the code information of the barcode is recognized based on the code information of the barcode read by the information reading unit 320 with reference to the symbol table, Spinning reel 310

It is possible to obtain game type information executed in the slot machine or arrangement information of the rotary reels 310 attached to the slot machine. When the third abnormality determination unit 734 determines that the official spinning reel is not attached to the slot machine, the notification unit 350 causes
Since the administrator is notified of that fact, it is possible to prevent a mistake in mounting the rotary reel 610 in the manufacturing process,
In addition, it is possible to prevent installation mistakes when changing the model or performing maintenance at the store at the management stage.

Further, according to the present embodiment, as compared with the slot machine according to the second embodiment, the light-shielding piece and the light-shielding piece detecting portion 970 are unnecessary, and the reset pulse signal is not necessary. The number of signal lines between the rotating reel side and the control section side can be reduced. Further, based on the read signal from the information reading unit 320, the barcode number counting unit 76
Since the number of barcodes read by 0 is counted and the rotation speed of the rotation reel 310 is detected by the rotation speed detection unit 738, the resolution of the information reading unit 320 (bar code reader or the like) is relatively low. Even if it is possible to detect the rotation speed of the rotating reel 310 and to determine the symbol, the device cost can be reduced. Further, since the barcode number counting unit 760 is realized by hardware, the operation clock of the CPU that realizes the control unit 730 can be suppressed to a low level.
The cost of the device can be reduced by using the inexpensive CPU.
