Description

  The present invention relates to a strip for recognizing a symbol position of a reel of a slot machine, a wheel for a symbol position detector of a mechanical slot machine, a symbol position detector of a mechanical slot machine, and a mechanical slot machine.

  Conventionally, there has been proposed an angle sensor that detects a rotation angle of a rotating shaft by forming a spiral slit in a disk fixed to the rotating shaft and detecting a light transmission position by an optical sensor (for example, a patent) Reference 1).

In the angle sensor described in Patent Document 1, a disc having a spiral slit is fixed to a rotating shaft, and when the rotating shaft rotates, a gap between the light emitting unit of the optical sensor and the light receiving unit facing the optical sensor is obtained. It is comprised so that the slit of a disc may pass. A linear position detection element is used as the light receiving unit. Utilizing the fact that the light receiving position of the light receiving portion changes when the disk rotates, the rotational position of the disk is detected from the light receiving position.

  As described above, a device has been proposed in which a disk is provided on a rotation shaft and the rotation angle of the rotation shaft or the rotation position of the disk is detected.

  However, when the device described in Patent Document 1 is used to detect the symbol position of each symbol applied to the reel over 360 ° as in the case of detecting the symbol position of the reel of the slot machine, the spiral is used. It is necessary to provide a slit in the shape of 360 °, and it is difficult to maintain a strength that does not deform when the disc is rotated together with the rotating shaft. When the deformation occurs, not only the accuracy of the angle sensor is lowered, but the angle sensor itself may be destroyed.

  In order to maintain the strength of the disk, an angle sensor is also known in which beams are provided at regular intervals in the slit. However, when the beam is at the position of the optical sensor, the rotational position of the disk cannot be detected. .

  The present invention relates to a belt-like body capable of directly detecting a symbol position of a reel having sufficient strength even when rotated with a reel of a slot machine, a symbol position detector wheel for a mechanical slot machine, and a symbol position of a mechanical slot machine using the same. An object is to provide a detector and a mechanical slot machine.

  (1) In order to achieve the above object, the belt-like body of the present invention, together with the reel, uses the rotation axis of the reel as a concentric axis to detect the symbol position of each symbol applied to the reel of the mechanical slot machine. A belt-like body provided in an annular shape along a peripheral edge of a rotatable wheel, the belt-like body having regions having different attributes from each other, and a boundary point of the region is one end in the length direction of the belt-like body As it goes from the side to the other end side, the band-shaped body is gradually approached or separated from one end side in the width direction to the other end side.

  As described above, when the band according to the present invention is used for detecting the symbol position, it is formed into a ring shape and fixed to the wheel. By adopting such a structure, the strength can be maintained so as not to be deformed even when the belt-like body is rotated.

  In addition, as described above, in the present invention, the boundaries of the regions having different attributes of the band-like body gradually approach or separate from one end side to the other end side in the width direction of the band-like body along the length direction of the band-like body. Thus, it is possible to specify the symbol position of the reel without rotating the reel only by detecting the position of the boundary point in the width direction of the regions having different attributes of the belt-like body. Therefore, it is possible to eliminate the need to provide a portion serving as a reference position on the belt-like body. In addition, the current symbol position of the reel can be detected without rotating the reel even immediately after the power is turned on. Further, when detecting the symbol position of the current reel, it is possible to eliminate the process of calculating the symbol position of the reel from the difference between the reference position of the strip and the current position. Also, since the current reel symbol position can be directly detected, it is not necessary to control the reel stop position by controlling a precise motor such as a stepping motor, and stop control is performed while monitoring the current reel symbol position. It is also possible. Therefore, it is possible to control the driving of the reel even if the reel does not reach a certain rotation speed. In addition, since the position in the width direction of the boundary point between the different areas of the belt-like body corresponds to the symbol position of the reel, it is easy even if the actual position deviates from the detected position due to the vibration of the housing.

  FIG. 2 is a diagram showing an electrical configuration of the mechanical slot machine according to the present embodiment. As shown in FIG. 2, the mechanical slot machine 1 is electrically composed of a main board A and a sub board B. In the main substrate A, the CPU 30 includes a ROM 31 and a RAM 32, and performs a control operation according to a preset program. In addition to a control program for controlling the operation of the mechanical slot machine 1, the ROM 31 stores a prize group lottery table and the like used for predetermining a prize group (internal lottery).

  The CPU 30 is connected to a clock generation circuit 33 that generates a reference clock pulse and a random number generation circuit 34 that generates a fixed random number. The CPU 30, ROM 31, RAM 32, and random number generation circuit 34 constitute a lottery device. A control signal sent from the CPU 30 is output via an output port 35 to a medal payout device 36 that pays out medals and a reel unit control unit 70 that controls a reel unit of the symbol display unit 7. The symbol display unit 7 and the reel unit 37 constitute a display unit.

  The signals output from the medal discriminating device 38 for discriminating the suitability of medals, the payout medal counter 40 for counting the number of medals to be paid out, and the start lever 41 for starting the rotation of the reels are sent to the CPU 30 via the input port 43. Entered. A signal output from the CPU 30 is output to the sub-board B via the data transmission circuit 46 under the control of the transmission timing control circuit 45 that controls the signal transmission timing to the sub-board B.

  In the sub-board B, the signal output from the data transmission circuit 46 is input to the data input circuit 47. The signal input to the data input circuit 47 is processed by the CPU 48. Connected to the CPU 48 are a clock generation circuit 49 that generates a reference clock pulse, a ROM 50 in which various programs and image data are recorded, and a RAM 51. Data relating to the image is output from the CPU 48 to the liquid crystal display 53 via the display circuit 52 that performs image processing and the like. The liquid crystal display 53 displays characters, still images, moving images, and the like. Further, data related to sound is output from the CPU 48 to the amplifier circuit 56 via the sound LSI 54 that performs sound processing and the like. The sound LSI 54 extracts necessary audio data from the audio ROM 55 and processes the audio data. Audio data that has undergone processing such as amplification by the amplifier circuit 56 is output to the speaker 58 via an audio adjustment circuit 57 that performs audio adjustment.

  FIG. 3 is a perspective view of the reel unit 37 of the mechanical slot machine according to the present invention. For example, when the symbol display unit 7 is configured by three reels, a reel unit is configured for each reel, and control such as rotation or stop is independently performed. The reel unit 37 is configured as follows. First, a lamp holder 63, a motor 64, and a sensor 65 are fixed to the reel body 62. As the motor 64, a stepping motor is used. However, it is not limited to a stepping motor, and a DC motor may be used. In the present invention, since the current reel symbol position can be directly detected, it is not necessary to control the reel stop position by controlling a precise motor such as a stepping motor, while monitoring the current reel symbol position, Stop control is also possible. Therefore, it is possible to control the driving of the reel even if the reel does not reach a certain rotation speed. A lamp 63 a is fixed to the lamp holder 63, and a shaft 66 as a rotating shaft is connected to the motor 64. A reel 67 and a wheel 68 are fixed to the shaft 66. A belt-like body 69 is fixed to the wheel 68 by being bent into an annular shape.

  As described above, when the band-like body 69 is used for position detection, it is formed into a ring shape and fixed to the wheel 68. By adopting such a structure, the strength can be maintained so as not to be deformed even when the belt-like body 69 is rotated. Moreover, since it is produced as the strip-shaped body 69 and it is not necessary to provide a slit in the strip-shaped body, fabrication and handling can be facilitated, and it is possible to facilitate fabrication of regions having different attributes.

  FIG. 4 is a side view of the reel unit 37 of the mechanical slot machine according to the present invention as viewed from the direction of the arrow C shown in FIG. As shown in FIG. 4, the lamp holder 63 is installed in the direction of the symbol display unit 7 so that the symbols on the reel 67 can be illuminated from the back to make the symbols easy to see.

  The light emitting unit 65 a and the light receiving unit 65 b of the sensor 65 are installed so as to face both surfaces of the strip 69. Further, since the reel 67 and the wheel 68 are both connected to a shaft 66 as a rotation axis, the central axes of rotation are the same. The band-like body 69 is bent in an annular shape and is fixed to the wheel so that both ends thereof are in contact with each other. Although omitted in FIG. 4, the lamp 63a and the sensor 65 are electrically connected to the CPU 30 through connectors and wiring.

  FIG. 5 is a perspective view of the main part when the reel unit 37 of the mechanical slot machine according to the present invention is disassembled. When the belt-like body 69 is not fixed to the wheel 68, the shape thereof is a rectangular sheet as shown in FIG.

  FIG. 6 is a block diagram showing an electrical configuration of the reel unit 37 and the reel unit controller 70 of the mechanical slot machine according to the present invention. As shown in FIG. 6, the reel unit 37 of the mechanical slot machine is electrically composed of a reel unit controller 70, a lamp 63 a, a motor 64, and a sensor 65. The sensor 65 includes a light emitting unit 65a and a light receiving unit 65b. The reel unit controller 70 includes a CPU 30, a ROM 31, a RAM 32, a clock generation circuit 33, and an output port 35, and performs a control operation according to a preset program. Further, the reel unit control unit 70 includes a storage unit 71 and a symbol specifying unit 72. The storage unit 71 composed of the ROM 31 and the RAM 32 has a control program for controlling the operation of the motor 64 by reflecting the detected symbol position of the reel in addition to a program for detecting the symbol position of the reel. Data in which positions and symbols are associated is stored in a table. In addition to the symbol, a blank (blank) portion may correspond to the position of the boundary point. Further, the data in which the position of the boundary point is associated with the symbol is not necessarily stored in the form of a table. The symbol specifying unit 72 inquires a table stored in the storage unit 71 from the position information of the boundary point detected by the program, and specifies the symbol currently displayed. Here, the symbol position of the reel refers to the state of the reel when each symbol on the reel is at a specific position. Specifically, if the boundary point of the strip 69 is Xp in the width direction and Yp in the length direction at the position of the sensor 65, the symbol position of the reel is specified.

  A control signal transmitted from the CPU 30 is output to the lamp 63 a, the motor 64, or the light emitting unit 65 a of the sensor 65 via the output port 35. Further, signals output from the light receiving unit 65 b of the sensor 65 and the central control board are input to the CPU 30 via the input port 43.

  The wheel 68, the belt-like body 69 as a belt-like portion fixed to the wheel 68, the sensor 65, the storage unit 71, and the symbol specifying unit 72 constitute a symbol position detector according to the present invention.

  As described above, in this embodiment, the reel unit control unit 70 configured by the CPU 30 and the like has a function of detecting the symbol position of the reel and controlling the operation of the reel unit reflecting the detected position of the symbol. A control board may be provided for each reel unit and installed in the reel body, and these functions may be included in the control board. In that case, the control board for each reel unit also serves to relay a signal between the CPU 30 and the reel unit 37.

  FIG. 7 is a perspective view of the sensor 65. The light emitting unit 65a of the sensor 65 has a function of irradiating the belt 69 with light, and includes, for example, an LED as a light emitting element. On the other hand, the light receiving portion 65 b of the sensor 65 includes a light receiving element 75, and a PTr (phototransistor) is used as an element of the light receiving element 75. In addition, PD (photodiode), photo IC, modulated light photo IC, or the like can be used as an element of the light receiving element 75. The light receiving element 75 is configured by a collection of elements that are units capable of detecting light reception. As shown in FIG. 7, the light receiving unit of the sensor has a configuration in which elements are arranged on a straight line. The number of elements per unit length is constant, for example, 16 pieces / mm. The sensor 65 is installed on the reel main body 62 so that the direction of the row of elements of the light receiving element 75 matches the width direction of the strip 69.

  FIG. 8 is a plan view of a strip 69a according to the present invention. The left side is colored black with the diagonal line as the boundary. In this embodiment, the attribute is light transmittance. A transparent plastic etc. can be used for the material of a strip | belt shaped object. When the attribute is light transmittance, for example, the band according to the present invention can be easily produced simply by printing a pattern with a black ink on a band made of a transparent plastic film. Note that any material that transmits light and can produce a light-shielding portion such as printing on the surface can be used in the same manner. As described above, the belt-like body 69a has regions having different light transmittances. As shown in FIG. 8, the boundary points of the regions having different light transmittances gradually move from the left side to the right side in the width direction of the strip 69a as it goes from the upper side to the lower side in the length direction of the strip 69a. .

  Thus, the symbol position of the reel 67 can be specified without detecting the rotation of the reel 67 only by detecting the position of the boundary point in the width direction of the belt-like body. Therefore, it is possible to eliminate the necessity of providing a portion serving as the reference position in the strip 69. Further, the current symbol position of the reel can be detected without rotating the reel 67 even immediately after the power is turned on. Further, when detecting the current position of the symbol, it is possible to eliminate the process of calculating the symbol position of the reel 67 from the difference between the reference position of the strip 69a and the current position. In addition, since the position in the width direction of the boundary point between the regions having different light transmittances of the band 69a corresponds to the symbol position of the reel 67, the position where the actual position is detected by the vibration of the casing You can easily fine-tune even if you deviate from the position

  In addition, since the boundary points of the regions having different attributes of the strip 69a have a continuous trajectory along the length direction, the symbol position of the reel can be detected with high accuracy. Hereinafter, unless otherwise specified, a boundary point between different attribute areas of the strip is simply referred to as a “boundary point”.

  Next, the operation of the mechanical slot machine according to the present embodiment configured as described above will be described. FIG. 9 is a flowchart showing a characteristic operation of the gaming machine according to the present embodiment.

  First, a normal game start operation is performed by a player's input (step S1). Here, as described above, the winning line is specified by the BET operation by the player, and the start lever 11 is operated.

  Next, a random number value for the stop number of the reel band in the first to third reels is acquired (step S2), and a winning line is determined (step S3). Next, rotation of the first to third reels is started (step S4). At this time, the symbol display unit 7 displays a state in which the symbols rotate and change in the display area of each reel. The direction of rotation may be from top to bottom or from bottom to top. Note that reels may be provided not only in the column direction but also in the row direction and rotated from left to right or from right to left.

  Next, the current symbol position of the reel is detected by the sensor (step S5). As shown in FIG. 10, for example, if the position in the width direction is at Xp for a certain boundary point, the position in the length direction is determined to be at Yp. Since Yp corresponds to the symbol position of the reel, the current symbol position of the reel can be directly detected. That is, the position Xp in the width direction of the boundary point may be considered as the symbol position of the reel itself. Therefore, when detecting the current symbol position of the reel, the conventionally required process of calculating the symbol position of the reel from the difference between the reference position of the strip and the current position can be eliminated. . In addition, the symbol specifying unit 72 can specify the currently displayed symbol by referring to a table in which the position in the width direction is associated with the symbol for the boundary point stored in the storage unit 71. In the following, the boundary points currently detected by the sensor are represented by Xp and Yp. The operation of the sensor at this time will be described below.

  FIG. 11 is a diagram illustrating a part of the light receiving element 75. Squares in the figure indicate elements constituting the light receiving element 75. In FIG. 11, light receiving elements represented by diagonal lines represent elements that do not receive light transmitted through the belt-like body. On the other hand, a light receiving element represented by white is a light receiving element that receives light transmitted through a belt-like body.

  As shown in FIG. 11, assuming that the nth light receiving elements are not receiving light and the (n + 1) th light receiving elements are receiving light, the elements per unit length in the light receiving element 75 are as follows. Since the number of installations is constant, the position of the boundary point in the width direction can be detected. For example, when the number of elements per unit length of the light receiving element 75 is 16 / mm, the number of elements is 128, and the length of the light receiving element is 8.00 mm, the light receiving element 75 detects If n is 50, Xp is 3.13 mm. Such processing is performed by the reel unit control unit 70.

  Next, the motor is driven from the position of the boundary point currently detected to the position of the boundary point to be stopped, and a signal for stopping at the position of the boundary point to be stopped is transmitted (step S6). Next, based on the signal transmitted from the reel unit controller 70, the rotations of the first to third reels are sequentially stopped (step S7). Here, the reels are sequentially stopped from the first reel toward the third reel at a predetermined time interval. The time interval can be 0.5 seconds, for example.

  For example, as shown in FIG. 12, when the symbol is to be stopped at the display position D, the position of the reel at the position Ys in the length direction of the boundary point of the belt-like body representing the symbol at the sensor position E Control the motor to stop rotation. Here, the symbol ★ corresponds to the position in the length direction of the boundary point from Ya to Yb, the position in the width direction from Xa to Xb, and the intermediate position Ys between Ya and Yb and the intermediate position Xs between Xa and Xb. It is assumed that the symbol is a representative value. Such a correspondence relationship is stored in advance in a storage unit configured by the RAM 32 as a table. In the reel 67 of FIG. 12, symbols other than ★ are omitted.

  Next, the current symbol position of the reel is detected by the sensor 65 (step S8). Specifically, the position Xp in the width direction of the boundary point of the strip 69a is detected at the position of the sensor 65. Next, the detected position information is collated with the position information transmitted to the motor in advance (step S9), and it is determined whether or not they match (step S10). Specifically, it is determined whether or not the position Xp in the width direction of the boundary point is within the range from the position Xa in the width direction corresponding to the ★ symbol to Xb. If it is not within the range, an error is displayed (step S11) and the machine is locked (step S12). In addition, when the position of the stopped symbol has shifted | deviated from the position which should be displayed, it is good also as correcting this by control of CPU30. If Xp is within the range of Xa to Xb, the process proceeds to step 13. Next, it is determined whether or not a winning is achieved (step S13). If no winning is achieved, the process returns to the game start standby state. On the other hand, if there is a prize, the number of medals stored (credit) is added as a prize payout (step S14). Then, the process returns to the game start standby state.

(Modification)
In the above-described embodiment, as shown in FIG. 8, the band-like body 69a whose left side is colored black with the diagonal line as a boundary is used. For example, the band-like bodies shown in FIGS. It may be used. FIG. 13 is a plan view of a strip 69b whose left side is colored black with a straight line inclined with respect to the length direction as a boundary. FIG. 14 is a plan view of a strip 69c whose boundary is drawn in a curved line. FIG. 15 is a plan view of a strip 69d in which only the diagonal line is colored black. In this case, since there are two boundaries on both sides of the straight line, it is necessary to create a program so that only boundary points on one boundary are detected in advance. FIG. 16 is a plan view of a strip 69e in which the black portion and the transparent portion are inverted with a certain length as a boundary with respect to the strip as shown in FIG. FIG. 17 is a plan view of a strip 69f having a pattern in which the strip as shown in FIG. 8 is cut at a certain length, replaced, and connected again. In this case, the boundary point has a one-to-one correspondence between the position in the width direction of the strip 69f and the position in the length direction.

  Also for such a band-like body, the same effect as the band-like body 69a as shown in FIG. 8 can be obtained. That is, the symbol position of the reel 67 can be specified without detecting the rotation of the reel 67 only by detecting the position of the boundary point. Therefore, it is possible to eliminate the need to provide a portion serving as the reference position on the belt-like body. Further, the current symbol position of the reel can be detected without rotating the reel 67 immediately after the power is turned on. Further, when detecting the current position of the symbol, the process of calculating the symbol position of the reel 67 from the difference between the reference position of the strip 69 and the current position can be eliminated.

  Further, since the position in the width direction of the boundary point directly corresponds to the symbol position of the reel, fine adjustment can be easily performed even if the actual position deviates from the detected position due to vibration of the housing.

  Further, since the position in the width direction and the position in the length direction of the strip 69 at the boundary point correspond one-to-one, the symbol position of the reel can be detected with high accuracy.

  Further, in the above embodiment, the belt-like body 69 is deformed into an annular shape and fixed to the wheel, but the same pattern as when the belt-like portion is provided in the wheel itself and the belt-like body 69 is annularly formed in the belt-like portion. The same effect can be obtained by creating.

  In the above embodiment, the sensor 65 is a transmissive optical sensor. However, a reflective optical sensor that detects a difference in lightness or chromaticity or a sensor that detects magnetic susceptibility may be used. When a reflection type optical sensor is used, the sensor 65 can be provided only on either the rotating shaft side or the reel side of the belt-like body 69. An LED or the like can be used as the light emitting element, and a PTr or the like can be used as the light receiving element 75, as in the above embodiment. In the case of using a sensor that detects a difference in lightness, as the band 69, for example, a white plastic with black printing can be used. As described above, when the attribute is lightness, the band according to the present invention can be easily produced. On the other hand, when using a sensor that detects a difference in chromaticity, for example, as the strip 69, a yellow plastic coated with a blue paint can be used. Thus, when the attribute is chromaticity, the band according to the present invention can be easily produced.

  When a sensor for detecting the magnetic permeability is used as the sensor 65, the sensor can be provided only on either the rotating shaft side or the reel side of the belt-like body, similarly to the reflective optical sensor. As the sensor, a magnetic sensor that reads a general magnetic tape or a magnetic card can be used. When the attribute is magnetism, the strip itself is magnetized, so that the sensor can be sufficiently configured if only the reading function is provided. As the band-like body 69, a film that has been coated with a plastic containing magnetic powder, etc., subjected to a certain treatment, and has a pattern that generates a certain magnetic permeability stored in the coating portion can be used.
