  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the best embodiment of the present invention will be described in detail with reference to the accompanying drawings.

<Overall configuration of pachinko machine>
FIG. 1 is a front view showing an external appearance of a pachinko machine 1000 as a game machine according to an embodiment of the present invention.

  On the game board 1100 of the pachinko machine 1000, a game area 1300 is formed by an outer rail 1210 and an inner rail 1220 arranged in a substantially circular shape, and a sky lamp 1410 is arranged above the game area 1300. In addition, a ball tray 1420 for storing pachinko balls is arranged below the game area 1300, and the game balls stored in the ball storage section of the ball tray 1420 can be extracted by operating the ball removal lever 1430. . Further, a launching handle 1440 that launches a pachinko ball and adjusts a flight distance is arranged on the side of the ball tray 1420.

  When the game ball is full in the ball storage portion of the ball tray 1420 and there is a problem in continuing the game, control such as forcibly stopping the launching device is performed. When the storage amount increases to some extent, it is desirable to display a warning so as to prompt the player to remove the ball. Therefore, in the pachinko machine 1000 of the present embodiment, a lighting device (detailed later) is provided on the ball removal lever 1430 so that the amount of storage in the ball storage portion of the ball tray 1420 reaches the player before reaching the danger zone. Warning notification is effectively performed.

  A relatively large variable display device 1500 is disposed in the approximate center of the game area 1300, and a normal symbol start gate 1510 is disposed on the left and right sides of the variable display device 1500. Also, below the variable display device 1500, a special symbol starting port 1520, a variable winning port 1530, a big winning port 1540, and an out port 1550 are arranged side by side. Further, a special symbol display 1560 and a special symbol hold lamp 1570, a normal symbol display 1580 and a normal symbol hold lamp 1590 are arranged below the right side of the game area 1300.

  A windmill 1310 and an obstruction nail 1320 are appropriately disposed at appropriate positions in the game area 1300 as game ball collision bodies that change in the flow direction when the game balls collide with each other. In the game area 1300, a winning opening 1330 is arranged at an appropriate place. The special symbol display 1560 and the normal symbol display 1580 are constituted by a so-called 7-segment display, a dot matrix display or the like, and can variably display numbers, symbols, and the like.

  Next, an outline of the pachinko game will be described. The hit ball launched by the player pushes the ball return prevention member 1230 through the shot ball passage formed by the outer rail 1210 and the inner rail 1220 and jumps into the game area 1300. The hit ball that has entered the game area 1300 flows down to the lower side of the game area 1300 according to the firing force and the contact state with the game ball contact body.

  When the game ball passes through the normal symbol start gate 1510 and is detected by the sensor, the normal symbol display 1580 is activated. When the variable display of the normal symbol display 1580 is stopped, if the stop mode is a predetermined mode, for example, “7” is stopped and displayed, the variable winning opening 1530 is activated and the ball is won. It changes to an easy state. Incidentally, the passage of the normal symbol start gate 1510 is stored up to a predetermined number, for example, four, and is displayed by the normal symbol hold lamp 1590.

  On the other hand, a hit ball flowing down the game area 1300 enters the special symbol start port 1520, and when this ball is detected by the sensor, the special symbol display 1560 is activated.

When the stop display mode of the special symbol display 1560 (substantially, the stop display mode in the variable display device 1500) becomes a predetermined mode, a so-called big hit is made and the big prize opening 1540 is opened, and the big prize opening The jackpot gaming state is easy to enter 1540.

  Note that the number of balls entered into the special symbol start opening 1520 is stored up to a predetermined number, for example, four, and is displayed by the special symbol hold lamp 1570. Since the information is of great interest to the player, for example, a special symbol hold display device 1600 is provided in the vicinity of the variable display device 1500 with high player visibility, and the number of balls entered into the special symbol start port 1520 is stored on hold. Can be displayed effectively. When the number of reserved memories reaches an upper limit value (for example, four), even if the ball enters the special symbol starting port 1520 after that, it will not be added to the reserved memory, and only a prize ball for the entered ball will be given. According to the player's judgment, it becomes easier to proceed with the game such that the firing operation is interrupted until the reserved memory is decremented.

<Game control processing>
Next, the outline of the game control process by the main control unit 701 will be described with reference to FIG. FIG. 3A is a flowchart regarding a reset interrupt, and FIG. 3B is a flowchart regarding a timer interrupt.

  First, in FIG. 3A, when the power is first turned on to the pachinko machine 1000, in step 101 (hereinafter abbreviated as S101), initialization such as initialization of each port and memory check is executed. Further, the subsequent processing is performed by conditional branching based on the determination result in the initial setting.

  In S102, when the power is normally restored after the power is turned off, the power is restored to the state before the power is shut off in S103.

  In S104, when it is detected that the RAM clear button provided in the power control unit 871 is operated during the above-described initialization process S101, or it is impossible to return to the RAM before the power is shut off. If it is determined, the RAM is forcibly cleared to erase all previous data. In S105, when the voltage of the power source supplied to the main control unit 701 is reduced to a value less than a specific value, it is detected whether a power source abnormality signal is generated from the power source monitoring unit. When a power failure signal is detected, power interruption processing, for example, port initialization, is executed. In S106, the soft random number is updated, and these processes are looped.

  The soft random number includes a so-called initial value random number counter that determines an initial value of a random number counter that determines whether or not a symbol is hit or missed. In addition, a random number initial value random number counter that determines the time for effect display in the special symbol display device 722, and a special symbol random number for determining the type of symbol to be stopped when the special symbol is displayed as a big hit. Includes a random number counter.

  In S107, which is a RAM error, the appropriate game progress cannot be expected, so the pachinko machine 1000 remains in a non-operating state.

  Next, the timer interrupt process in FIG. 3B will be briefly described. This timer interrupt processing indicates basic control of the game in the pachinko machine 1000.

  First, in S201, the register contents are saved in the RAM as a register saving process.

  In S202, each input port data is acquired as input port acquisition processing. For example, the detection state of sensors provided in the normal symbol start gate 1510, the special symbol start port 1520, and the like is acquired.

  In S203, a soft random number update process is executed. As described above, this soft random number update determines the initial value of the random number, the random number counter, the random number counter for determining whether or not the normal symbol is hit or missed, and the time for effect display on the special symbol display device 722. When the random number counter and the special symbol are stopped and displayed as a big hit, the special figure random number counter for determining the type of symbol to be stopped and displayed is updated. When the predetermined random number counter reaches the initial value, the value of the predetermined random number counter is replaced with the value of the corresponding initial value random number counter.

  In S204, a winning detection process is executed to monitor whether or not there is a winning at the starting port (special symbol starting port 1520) or winning port (winning port 1330, variable winning port 1530, large winning port 1540). If there is a winning at the winning opening, the number of winning balls is counted up. Specifically, based on the fact that a game ball has won a winning opening, a predetermined number of winning balls for the winning opening is added to a winning ball counter provided in the RAM 715. Further, when the special symbol start port 1520 has won a prize and the holding number is less than 4, the counter circuit 718 is latched, and the output value from the counter circuit 718 is acquired as a special figure large random number value. The special figure random number value and the special figure production random number value are acquired from the special figure random number counter and the special figure production timer random number counter included in the random number counter updated in the soft random number update S203 of FIG. Further, when the ball passes through the normal symbol start gate 1510 and the number of holdings is less than 4, the normal symbol random number value is calculated from the common symbol random number counter included in the random number counter updated in the above-described soft random number update S203. Get and hold.

  In S205, special figure related processing is executed. In this special symbol related processing, a predetermined stop display time and a predetermined lottery interval time have elapsed since the symbol was stopped and displayed on the special symbol display unit 722, and it is not a big hit, and the above-described winning detection S204 When a random number related to a special figure is reserved, special symbol-related processing is performed using the reserved random number. First, it is determined whether or not the special figure jackpot random number value matches a predetermined jackpot determination value. If they match, a jackpot flag is set. That is, information indicating that a big hit is stored in the big hit determination result storage area of the RAM 715. If they do not match, information indicating that the game is lost is stored in the jackpot determination result storage area. If the big hit flag is set and the special symbol random number is a specific value, the special symbol display unit 722 is stopped and displayed, and after the big hit operation is started / finished, the special symbol display unit 722 Information indicating that the probability variation state is likely to be a big hit again is stored in the RAM 715. This is referred to as setting a probability variation flag. If the value is not a specific value, information indicating that the probability variation state is not set is stored in the RAM 715. Based on whether the big hit flag is set, whether the probability change flag is set, and the value of the special figure effect random value, the time from the start of the variable symbol display on the special symbol display unit 722 to the stop display is determined. And stored in the RAM 715. This is referred to as variation time. In the special figure related process, the number of holds is updated.

  In S206, a common map related process is executed. In this common symbol related process, a predetermined stop display time and a predetermined lottery interval time have elapsed since the symbol was stopped and displayed on the normal symbol display unit 724, and the winning symbol detection S204 described above is not successful. When a random number related to a general drawing is held, processing related to normal symbols is performed using the held random number. First, it is determined whether or not the regular random number value matches a predetermined hit determination value. If they match, a hit flag is set. That is, information indicating that the winning is made in the hit determination result storage area of the RAM 715 is stored. If they do not match, information indicating that the game is lost is stored in the hit determination result storage area. In addition, the common map-related process performs an update operation such as the number of holds.

  In S207, a control command transmission process is executed. The control command indicates a payout command and an effect command. As for the payout command, if the number of prize balls is counted up in the above-described processing of S204, that is, if the prize ball number counter provided in the RAM 715 is not zero, the value of the prize ball number counter is included in the payout command. To the payout control unit 801. Upon receiving the payout command, the payout control unit 801 drives and controls the payout device 802 so as to pay out the number of prize balls included in the command. The effect command is transmitted to the command including the above-described variation time, the variation stop command, and the sub-control unit 751. Specifically, the main control unit 701 outputs a signal including the value of the big hit flag, the probability variation flag, and the variation time to the sub control unit 751. As a result, the sub-control unit 751 drives various lamps 773 and the speaker 771 based on the information included in the received signal, and outputs a control signal to the liquid crystal control circuit 768 to start a variable display on the LCD 769. . Further, in the control command transmission process S207 in the next interrupt process in which information indicating that the fluctuation time has elapsed in the timer update S209, which will be described later, is written in the RAM 715, the fluctuation stop process is started. That is, a signal including information instructing the sub-control unit 751 to stop the fluctuation is output. As a result, the sub-control unit 751 drives the various lamps 773 and the speaker 771 based on the information included in the received signal, and outputs a control signal to the liquid crystal control circuit 768 to indicate that the special symbol is stopped on the LCD 769. The display of the image to produce is started. Further, in the control command transmission process S207 in the next interrupt process set at the timing for starting the big hit in the timer update S209 described later, the big hit process is started. That is, information indicating that the big hit is started is output to the sub-control unit 751. As a result, the sub-control unit 751 drives various lamps 773 and the speaker 771 based on the information included in the received signal, and outputs a control signal to the liquid crystal control circuit 768, thereby producing an image that produces a big hit on the LCD 769. Start display.

  In S208, port output processing is executed. In this port output processing, display control signals of various displays (for example, special symbol display unit 724, normal symbol display unit 724, etc.), a solenoid 728 that opens and closes the doors of the big prize opening 1540 and the blades of the variable prize opening 1530 are opened and closed. A signal for opening or closing is output, and output control of an external signal is performed on the information input circuit 999 included in the management apparatus of the game store.

  In S209, a timer update process is executed. In this timer update process, the elapse of the variation time determined in the special figure related process S205 is monitored, and the elapse of a predetermined stop display time is monitored. After the predetermined stop display time has elapsed, when the jackpot flag is set, each time of the jackpot operation (for example, the interval before the jackpot start, the bonus opening opening time, the bonus opening closing time, the jackpot end interval) Monitor progress. When the big win flag is not raised, the predetermined lottery interval time is monitored, and when the predetermined lottery interval time elapses, the next special symbol change can be started. The same processing is performed for the normal symbol display section and the variable winning opening.

  In S210, register return processing is executed. That is, the data saved in the register saving process of S201 described above is written again into the register.

The photorefractive member 20 is disposed on the front side of the first to third LEDs 1432a to 1432c, facing the front side through the 1LED introduction hole 1431a, the second LED introduction hole 1431b, and the third LED introduction hole 1431c. Thereby, the light of the first to third LEDs 1432a to 1432c incident from the rear surface that is the incident surface of the light refracting member 20 is transmitted while being appropriately refracted, and is irradiated from the front surface that is the output surface of the light refracting member 20. Configure.

  The light refracting member 20 is provided with a first condensed image generating means 21 (described later in detail) on the incident surface 201 side which is the rear surface of the transparent sheet member 200 having an arbitrary shape, and on the output surface 202 side which is the front surface. Two condensed image generation means 22 (detailed later) are provided, and it is possible to view from the front side a complicated and various light emission mode that is difficult to imagine from the irradiation light source by the first to third LEDs 1432a to 41432c. That is, even if the first to third LEDs 432a to 432c, which can be regarded as point light sources, are used as the light source, a complicated and interesting light emission mode can be seen from the front side of the photorefractive member 20, so that it is relatively inexpensive. A highly decorative lighting effect can be achieved with the configuration.

  A front cover member 1433 formed of clear resin or the like is provided on the front surface side of the base member 1431, and a back surface cover member 1434 that covers the LED substrate 1432 is provided on the back surface side of the base member 1431.

For example, a separate lighting device may be assembled to a required portion of the ball removal lever. .

<First Embodiment of Photorefractive Member>
Next, based on FIGS. 5-8, the specific structure and principle of the photorefractive member 20 which concern on 1st Embodiment are demonstrated.

  In FIG. 5, in order to explain the principle of the photorefractive member 20 according to the present embodiment, the first condensed image generating means 21 is provided on the incident surface of the transparent sheet member 200 ′, and the exit surface 202 ′ is not uneven. A light refracting member 20 'having a flat surface is shown. FIG. 5A shows a first arrangement in which regular tetragonal pyramidal refracting elements 211 projecting from an incident-side transmission reference plane 201 ′ (for example, a virtual plane substantially parallel to the exit plane 202 ′) are arranged in a matrix in the vertical and horizontal directions. The back surface (incident surface) of transparent sheet member 200 'which has the condensed image production | generation means 21 is shown, The approximate center is a circular illumination area | region. FIG. 5B shows the upper surface (or bottom surface) of the transparent sheet member 200 ′, and the light emission source 23 is arranged at a position relatively close to the incident surface. FIG. 5C shows the front surface of the transparent sheet member 200 ′, which is a flat emission surface 202 ′, and a first condensed image 212 including a plurality of high luminance regions appears.

  The refractive element body 211 of the first condensed image generating means 21 has four inclined refracting surfaces A, B, C, and D that are continuous with the four sides of the base surface that is flush with the incident-side transmission reference surface 201 ′. For example, a first alignment arrangement line in which the inclined refracting surface A and the inclined refracting surface C are aligned and a second alignment line in which the opposing inclined refracting surface B and the inclined refracting surface D are aligned are generated, and light emission occurs. The light emitted from the source 23 is easily refracted in the vertical direction that is the first alignment line and the horizontal direction that is the second alignment line, and a high-luminance region is formed in which incident light is condensed at the four points in the vertical and horizontal directions. As a result, a substantially cross-shaped first condensed image 212 as shown in FIG. 5C is generated. By changing the distance from the light emitting source 23 to the incident surface, the protrusion amount of the refracting element 211, the inclination angle of the inclined refracting surface, or the like, the position where the high luminance region is generated in the aligned arrangement line direction can be controlled to some extent. .

  The refractive element body 211 constituting the first condensed image generating means 21 has a minute shape with a short arrangement interval so that unevenness is not felt when touched with a finger, and is integrally molded with the transparent sheet member 200 'or transparent The incident surface of the sheet member 200 ′ is formed by processing, and when light is transmitted from the first condensed image generating unit 21 to the transparent sheet member 200 ′, a region having a non-uniform refractive index based on a medium difference is formed. It did not occur. The size of the refractive element 211 is not particularly limited, and depends on various conditions such as the illuminance and illumination area size of the light source 23 and the refractive index specific to the material of the transparent sheet member 200 ′. What is necessary is just to make the 1st condensing image 212 appear in the range of '.

  Next, FIG. 6 shows that the incident surface of the transparent sheet member 200 passes through the first condensing image generating means 21 (the same refractive element body 211 as the first condensing image generating means 21 described in FIG. 2 shows a photorefractive member 20 provided with a structure in which the reference surface 201 is arranged in a line without any gap and the second condensed image generating means 22 is provided on the exit surface. 6A shows the back surface of the transparent sheet member 200 having the first condensed image generating means 21 in which regular tetragonal pyramidal refracting elements 211 protruding from the incident-side transmission reference surface 201 are arranged in a matrix in the vertical and horizontal directions. The approximate center is a circular illumination area. FIG. 6B shows the top surface (or bottom surface) of the transparent sheet member 200, and the light emission source 23 is disposed at a position relatively close to the incident surface. FIG. 6C shows the front surface of the transparent sheet member 200 having the second condensed image generating means 22 in which regular tetragonal pyramidal refracting elements 221 protruding from the emission-side transmission reference surface 202 are arranged vertically and horizontally in a matrix. 2nd collected image 222 from the position corresponding to each high-intensity area (upper and lower left and right 4 points) of the first condensed image generated on the outgoing side transmission reference plane 201 by the first condensed image generating means 21. Appears.

  The refractive element body 221 of the second condensed image generating means 22 includes four inclined refracting surfaces A, B, C, and D that are continuous with the four sides of the square base that is flush with the outgoing-side transmission reference surface 201. Thus, for example, a first alignment line in which the inclined refracting surface A and the inclined refracting surface C are aligned and a second alignment line in which the opposing inclined refracting surface B and the inclined refracting surface D are aligned are generated. When the light in each of the four high-intensity regions in the upper and lower left and right directions in the condensed image 212 passes through the second condensed image generating means 22, the upper and lower directions that are the first alignment line and the left and right that are the second alignment line. A high-intensity region in which incident light is condensed at four points on the top, bottom, left, and right is easily refracted in the direction, and is formed at four places on the top, bottom, left, and right, so that a second condensed image having a substantially cross shape as shown in FIG. 222 occurs in four places at the top, bottom, left and right.

  If the refractive element body 211 of the first condensed image generating means 21 and the refractive element body 221 of the second condensed image generating means 22 have the same shape, the first shape of the first approximated image 212 is approximated. Although the two condensed images 222 can be generated, the refractive element body 211 of the first condensed image generating means 21 and the refractive element body 221 of the second condensed image generating means 22 can be enlarged or reduced with a similar shape. By changing the protrusion amount of the refracting element body 221 and the inclination angle of the inclined refracting surface, the light emission form of the second condensed image 222 (the size of the high luminance region, the separation distance, etc.) can be variously changed. .

  Similar to the first condensed image generating means 21 described above, the refractive element body 221 constituting the second condensed image generating means 22 is also a minute shape with a short arrangement interval so that no irregularities are felt when touched with a finger. It is formed by integrally molding with the transparent sheet member 200 or by processing the exit surface of the transparent sheet member 200, and when transmitting light from the transparent sheet member 200 to the second condensed image generating means 22, It is assumed that a region having a non-uniform refractive index due to a medium difference does not occur. Of course, the size of the refractive element body 221 is not particularly limited, and a plurality of the refractive element bodies 221 may be selected depending on various conditions such as the position and illuminance of the high luminance region in the first condensed image 212 and the refractive index specific to the material of the transparent sheet member 200. The second condensed image 222 may be made to appear.

  In addition, since the first and second condensed image generating units 21 and 22 in the photorefractive member 20 of the present embodiment are arranged so that the refractive element bodies 211 and 221 are arranged without gaps, the incident-side transmission reference plane 201 and Although the exit-side transmission reference surface 202 does not appear on the surface, for example, when the refractive element bodies 211 and 221 are arranged in a line while being slightly separated from each other, the incident-side transmission reference surface 201 is formed at a distance between the refractive element bodies 211 and 221. , The outgoing-side transmission reference plane 202 appears.

  Next, FIG. 7 shows that the first condensed image generating means 21 (the same refractive element body 211 as the first condensed image generating means 21 described in FIGS. 5 and 6 is provided on the incident surface of the transparent sheet member 200. The light refracting member 20 is provided in which the outgoing side transmission reference surface 201 is arranged in a line without any gap and the second condensed image generating means 22 'is provided on the outgoing surface. 7A shows the back surface of the transparent sheet member 200 having the first condensed image generating means 21 in which regular tetragonal pyramidal refracting elements 211 protruding from the incident-side transmission reference surface 201 are arranged in a matrix in the vertical and horizontal directions. The incident surface is shown, and the approximate center thereof is a circular illumination area. FIG. 7B shows the upper surface (or bottom surface) of the transparent sheet member 200, and the light emission source 23 is disposed at a position relatively close to the incident surface. FIG. 7C shows a regular quadrangular pyramid-shaped refracting element 221 protruding from the outgoing-side transmission reference plane 202 in an oblique direction (an angle of 45 degrees with the arrangement direction of the refracting elements 211 in the first condensed image generating means 21). The front surface of the transparent sheet member 200 having the second condensed image generating means 22 ′ arranged in alignment in the direction of forming the first condensed light generated on the output side transmission reference surface 202 by the first condensed image generating means 21. Second condensed images 222 ′ appear from positions corresponding to the high-intensity regions (four points on the top, bottom, left, and right) of the image.

  The refractive element body 221 of the second condensed image generating means 22 'has a bottom surface that is flush with the outgoing-side transmission reference surface 202, and has four inclined refracting surfaces A, B, C, and D connected to the four sides. For example, a first alignment line in which the inclined refracting surface A and the inclined refracting surface C are aligned with each other, and a second alignment line in which the opposing inclined refracting surface B and the inclined refracting surface D are aligned are generated, The light in each of the four high-brightness regions in the upper, lower, left, and right sides of the one condensed image 212 passes through the second condensed image generating means 22 in the oblique direction that is the first alignment line (in FIG. Or, it is easily refracted in the second alignment line, that is, the slant direction (in FIG. 7, the slant direction that is up or down to the left), and is incident at four points: top right, bottom right, top left, and bottom left. High-intensity areas where light is collected are generated in four locations, top, bottom, left, and right. Accordingly, it is a second Atsumarihikarizo 222 of substantially X-shape as shown in FIG. 7 (c) 'that occurs vertically and horizontally four places.

  The generation mode change of the second condensed image will be specifically described. As shown in FIG. 8A, the first aligned arrangement line L1 of the second condensed image generating unit 22 is the first condensed image generating unit. The second aligned arrangement line L2 of the second condensed image generating means 22 is aligned with the first aligned arrangement line of the first condensed image generating means 21 (for example, for example, the vertical direction). Horizontal direction), the second condensed image 222a in which two high-intensity regions are generated in the vertical direction and the horizontal direction from the four points corresponding to the high-intensity region of the first condensed image respectively appears. As shown in FIG. 8B, the first aligned arrangement line L1 and the second aligned arrangement line L2 of the second condensed image generating means 22 are replaced with the first aligned arrangement line of the first condensed image generating means 21 and the second aligned arrangement line L2. If the angle α1 (for example, 22.5 degrees) is rotated clockwise from the alignment line, As shown in FIG. 8C, the second condensed image generation means 22 appears as shown in FIG. 8C. When the first aligned arrangement line L1 and the second aligned arrangement line L2 are rotated clockwise by an angle α2 (for example, 45 degrees) from the first aligned arrangement line and the second aligned arrangement line of the first condensed image generation unit 21. The second condensed image 222c, which is similar to the second condensed image 222a of FIG. 8A and is inclined clockwise by the angle α2, appears, and as shown in FIG. 8D, the second condensed image The first aligned arrangement line L1 and the second aligned arrangement line L2 of the generation unit 22 are rotated clockwise from the first aligned arrangement line and the second aligned arrangement line of the first condensed image generating unit 21 by an angle α3 (for example, 67.5). Degree), the second condensed image 222 in FIG. Second Atsumarihikarizo 222d inclined by an angle α3 leave clockwise shape similar appears. Further, the first aligned arrangement line L1 and the second aligned arrangement line L2 of the second condensed image generating means 22 are rotated clockwise or counterclockwise from the first aligned arrangement line and the second aligned arrangement line of the first condensed image generating means 21. When rotated 90 degrees clockwise, the first aligned arrangement line L1 of the second condensed image generating means 22 coincides with the second aligned arrangement line (for example, the horizontal direction) of the first condensed image generating means 21, and the second Since the second aligned arrangement line L2 of the two condensed image generating means 22 coincides with the first aligned arrangement line (for example, the vertical direction) of the first condensed image generating means 21, the second condensed light line in FIG. A second condensed image having substantially the same shape as the image 222a appears.

  That is, by changing the direction of the exit side alignment line in the second focused image generation unit 22 relative to the incident side alignment line in the first focused image generation unit 21, the second focused image is changed. The generation mode of can be changed. As described above, in the photorefractive member 20 according to the present embodiment, the refractive element body 211 of the first condensed image generating means 21 and the refractive element body 221 of the second condensed image generating means 22 may be used as the same shape. By simply changing the direction of the alignment line, it is possible to realize a light emission mode that is not interesting in the past. In addition, by making the shapes of the refractive element body 211 of the first condensed image generating means 21 and the refractive element body 221 of the second condensed image generating means 22 different, variations in the light emission mode can be varied.

<Second Embodiment of Photorefractive Member>
Next, based on FIGS. 9-11, the specific structure and principle of the photorefractive member 30 which concern on 2nd Embodiment are demonstrated.

  FIG. 9 illustrates the principle of the light refracting member 30 according to the present embodiment, in which the first condensed image generating means 31 is provided on the incident surface of the transparent sheet member 300 ′, and the exit surface 302 ′ is flat without unevenness. A light refracting member 30 ′ as a surface is shown. FIG. 9A shows the back surface (incident surface) of the transparent sheet member 300 ′ having the first condensed image generating means 31 in which the triangular pyramid-shaped refractive element bodies 310 protruding from the incident-side transmission reference surface 301 ′ are aligned. The approximate center is a circular illumination area. FIG. 9B shows the upper surface (or bottom surface) of the transparent sheet member 300 ′, and the light emission source 33 is arranged at a position relatively close to the incident surface. FIG. 9C shows the front surface of the transparent sheet member 300 ′, which is a flat emission surface 302 ′, and a first condensed image 313 including a plurality of high luminance regions appears.

  The refractive element body 310 of the first condensed image generating means 31 is an isosceles triangle (including an equilateral triangle in which a pair of oblique sides and base sides have the same length) whose bottom surface is flush with the incident-side transmission reference surface 301 ′. It is provided with three inclined refracting surfaces connected to a certain three sides. The refractive element body 310 is referred to as a first group refractive element body 311 and a second group refractive element body 312 depending on the direction in which the refractive element bodies are aligned. For example, in the first group refractive element 311, the inclined refracting surface A connected to the base of the isosceles triangle that is the bottom shape is on the lower side, and the apex at which the inclined refracting surfaces B and C connected to the oblique side intersect is on the upper side. In the second group refractive element body 312, the inclined refracting surface “a” connected to the base of the isosceles triangle having the bottom shape is on the upper side, and the apex at which the inclined refracting surfaces “b” and “c” connected to the oblique side intersect is on the lower side. The first group element body 311 and the second group refractive element body 312 are alternately arranged in the horizontal direction, and the bottom side (side where the inclined refractive surface A rises) and the second side of the bottom surface of the first group refractive element body 311 are arranged. The arrangement of the refractive element bodies 310 was realized by arranging the base elements 312 in the vertical direction so as to coincide with the bottom of the bottom surface of the group element body 312 (the side on which the inclined refractive surface a rises).

  According to this arrangement structure, the first alignment arrangement line L1 in which the inclined refractive surface A of the first group refractive element body 311 and the inclined refractive surface a of the second group refractive element body 312 are aligned with each other, and the first opposite to each other. A second alignment line L2 in which the inclined refractive surface B of the group refractive element 311 and the inclined refractive surface b of the second group refractive element 312 are aligned, and the inclined refractive surface C of the first group refractive element 311 and the second A third alignment line L3 is formed in which the inclined refractive surfaces c of the second group refractive element bodies 312 are aligned. In the refractive element body 310 having a regular tetrahedron shape (the bottom surface and the three inclined refracting surfaces are all regular triangles), the first alignment line L1 and the second alignment line L2 have an angle of 60 degrees clockwise. Since the first and third alignment lines L1 and L2 form an angle of 120 degrees clockwise, the first to third alignment lines L1 to L3 appear at equal intervals every 60 degrees. Become.

  The light irradiated from the light emitting source 33 on the incident surface of the light refracting member 30 ′ thus configured is easily refracted selectively in the directions of the first to third alignment lines L 1 to L 3. As a result of a high luminance region where incident light is collected at a point, an asterisk-shaped first condensed image 313 as shown in FIG. 9C is generated on the exit surface 302 ′. By changing the distance from the light emitting source 33 to the incident surface, the protruding amount of the refractive element 310, the inclination angle of the inclined refracting surface, or the like, the position where the high luminance region is generated in the aligned arrangement line direction can be controlled to some extent. .

  Next, FIG. 10 shows that the first condensing image generating means 31 (the same refractive element body 310 as the first condensing image generating means 31 described in FIG. The photorefractive member 30 is shown in which the reference plane 301 is provided with an arrangement arrangement structure in which the reference plane 301 is arranged without gaps, and the second condensed image generating means 32 is provided on the exit surface. FIG. 10A shows a first tetrahedral refracting element 310 (consisting of a first group refracting element 311 and a second group refracting element 312) arranged in a line, which projects from the incident side transmission reference surface 301. The back surface of the transparent sheet member 300 which has the condensed image production | generation means 31 is shown, The approximate center is a circular illumination area | region. FIG. 10B shows the upper surface (or the bottom surface) of the transparent sheet member 300, and the light emitting source 33 is arranged at a position relatively close to the incident surface. FIG. 10C shows a second collection in which triangular pyramid-shaped refractive element bodies 320 (consisting of a first group refractive element body 321 and a second group refractive element body 322) protruding from the output-side transmission reference surface 302 are arranged. The front surface of the transparent sheet member 300 having the light image generating means 32 is shown, and each high-intensity region (hexagonal 6) of the first condensed image generated on the emission-side transmission reference surface 302 by the first condensed image generating means 31 is shown. The second condensed image 323 appears from the position corresponding to the point) through the second condensed image generating means 32.

  The refractive element body 320 of the second condensed image generating means 32 is an isosceles triangle whose bottom surface is flush with the transmission-side transmission reference surface 302 (including an equilateral triangle in which a pair of hypotenuse length and base length are the same). It is provided with three inclined refracting surfaces connected to three sides, and is referred to as a first group refracting element body 321 and a second group refracting element body 322 according to the direction in which they are aligned. For example, in the first group refractive element body 321, the inclined refracting surface A connected to the base of the isosceles triangle that is the bottom shape is on the lower side, and the apex at which the inclined refracting surfaces B and C connected to the oblique side intersect is on the upper side. In the second group refractive element 322, the inclined refracting surface “a” connected to the base of the isosceles triangle having the bottom shape is on the upper side, and the apex at which the inclined refracting surfaces “b” and “c” connected to the oblique side intersect is on the lower side. Then, the first group element bodies 321 and the second group refractive element bodies 322 are alternately arranged in the lateral direction, and the bottom side (side where the inclined refractive surface A rises) and the second side of the bottom surface of the first group refractive element body 321 are arranged. The arrangement of the refractive element bodies 320 similar to that of the refractive element body 310 was realized by arranging the base elements 312 in the vertical direction so as to coincide with the bottom side (side where the inclined refractive surface a rises) on the bottom surface.

  According to this arrangement structure, the first alignment arrangement line L1 in which the inclined refractive surface A of the first group refractive element body 321 and the inclined refractive surface a of the second group refractive element body 322 are aligned with each other, and the first opposing arrangement line L1. The second alignment arrangement line L2 in which the inclined refractive surface B of the group refractive element body 321 and the inclined refractive surface b of the second group refractive element body 322 are aligned, and the inclined refractive surface C of the first group refractive element body 321 and the second A third alignment line L3 in which the inclined refractive surfaces c of the second group refractive element bodies 322 are aligned is generated. In the refracting element body 320 having a regular tetrahedron shape, the first alignment line L1 and the second alignment line L2 form an angle of 60 degrees clockwise, and the first alignment line L1 and the third alignment line L1 form the third alignment line L1. Since the arrangement line L2 forms an angle of 120 degrees clockwise, the first to third aligned arrangement lines L1 to L3 appear at equal intervals every 60 degrees.

  The light of the light refracting member 30 configured as described above is irradiated with light from the light source 33, and the light in the six high-luminance regions in the first condensed image 313 generated on the emission-side transmission reference surface 302 is When passing through the two condensing image generating means 32, a high-luminance region in which incident light is condensed at six points of regular hexagons is easily refracted in the first to third aligned arrangement lines L1 to L3. As a result, asterisk-shaped second condensed images 323 as shown in FIG. 10C are respectively generated at six points of the regular hexagonal shape.

  If the refractive element body 310 of the first condensed image generating means 31 and the refractive element body 320 of the second condensed image generating means 32 have the same shape, the first shape of the first approximated image 313 is approximated. Although the two condensed images 323 can be generated, the refractive element body 310 of the first condensed image generating means 31 and the refractive element body 320 of the second condensed image generating means 32 can be enlarged or reduced with a similar shape. By changing the protrusion amount of the refractive element 320 and the inclination angle of the inclined refracting surface, the light emission mode (the size of the high brightness region, the separation distance, etc.) of the second condensed image 323 can be variously changed. .

  The change in the generation manner of the second condensed image in the photorefractive member 30 of this embodiment will be specifically described. As shown in FIG. 11A, the first aligned arrangement line L1 of the second condensed image generating means 32 is illustrated. Coincides with the first aligned arrangement line (for example, in the vertical direction) of the first condensed image generating means 31, and the second aligned arrangement line L 2 of the second condensed image generating means 32 corresponds to the first condensed image generating means 31. The third aligned arrangement line L3 of the second condensed image generating means 32 is aligned with the second aligned arrangement line (for example, the 60 ° clockwise tilt direction), and the third aligned arrangement line L3 of the first condensed image generating means 31 ( For example, if it is coincident with the 120 ° clockwise direction, the vertical direction, 60 ° clockwise direction and 120 ° clockwise direction from the 6 points corresponding to the high brightness area of the first condensed image are 2 respectively. Each second condensed image 323a in which a high-intensity region of points appears is shown in FIG. As shown, the first to third aligned arrangement lines L1 to L3 of the second condensed image generating means 32 are angled α1 (for example, clockwise from the first to third aligned arrangement lines of the first condensed image generating means 31). , 20 degrees), a second condensed image 323b that is inclined in the clockwise direction by an angle α1 appears similar to the second condensed image 323a in FIG. 11A, as shown in FIG. 11C. In addition, the first to third aligned arrangement lines L1 to L3 of the second condensed image generating unit 32 are respectively rotated clockwise from the first to third aligned arrangement lines of the first condensed image generating unit 31 by an angle α2 (for example, When rotated by 40 degrees, a second condensed image 323c appears in the clockwise direction while being similar to the second condensed image 323a in FIG. Further, the first to third aligned arrangement lines L1 to L3 of the second condensed image generating means 32 are 60 degrees clockwise or counterclockwise from the first to third aligned arrangement lines of the first condensed image generating means 31. Alternatively, when rotated by 120 degrees, the first aligned arrangement line L1 of the second condensed image generating means 32 coincides with the second aligned arrangement line or the third aligned line of the first condensed image generating means 31, and the second condensed light is obtained. The second aligned arrangement line L2 of the image generating means 32 coincides with the third aligned arrangement line of the first condensed image generating means 31 or the first aligned arrangement line. Since L3 coincides with the first aligned arrangement line or the second aligned arrangement line of the first condensed image generating means 31, a second condensed image having substantially the same shape as the second condensed image 323a of FIG. appear.

  That is, also in the photorefractive member 30 according to the present embodiment, the direction of the exit-side aligned arrangement line in the second condensed image generating unit 32 is relative to the incident-side aligned arrangement line in the first condensed image generating unit 31. Therefore, the generation mode of the second condensed image can be changed. Thus, in the photorefractive member 30 according to the present embodiment, the refractive element body 311 of the first condensed image generating means 31 and the refractive element body 321 of the second condensed image generating means 32 may be used as the same shape. By simply changing the direction of the alignment line, it is possible to realize a light emission mode that is not interesting in the past. In addition, by varying the shape of the refractive element body 311 of the first condensed image generating means 31 and the shape of the refractive element body 321 of the second condensed image generating means 32, variations in the light emission mode can be varied.

<Third Embodiment of Photorefractive Member>
Further, the refractive element body of the first condensed image generating means and the refractive element body of the second condensed image generating means are not limited to a regular tetrahedron shape. For example, the bottom surface is a regular triangle and three inclined refracting surfaces. Even when the refracting elements having an isosceles triangle are aligned and arranged, the first to third aligned arrangement lines L1 to L3 can be generated at equal intervals. In addition, the base shape of the refractive element is not limited to an equilateral triangle or an isosceles triangle. If the arrangement line can be generated, the light emission mode change of the second condensed image can be controlled according to the direction of the aligned arrangement line, and the second condensed image in a form that is not predicted can be obtained. In addition, the size of the refractive element body of the first condensed image generating means and the refractive element body of the second condensed image generating means can be changed, or the first condensed image generating means and the second condensed image generating means can be changed. Even if the tilt angle of the tilted refracting surfaces of both refractive element bodies is changed or the relative orientation of the alignment line is changed between the first and second condensed image generating means. The shape of the two condensed images can be changed more variously.

  For example, the light refracting member 40 according to the third embodiment shown in FIG. 12 has the first condensed image generating means 41 (according to the second embodiment) on the incident surface of the transparent sheet member 400 (see FIG. 12C). Similar to the first condensed image generating means 31 of the photorefractive member 30, the refractive element body 410 composed of the first group refractive element body 411 and the second group refractive element body 412 having a substantially triangular pyramid shape is used as the incident-side transmission reference surface 401. And a second condensing image generating means 42 (like the first condensing image generating means 41) on the exit surface (see FIG. 12A). A structure in which a refractive element body 420 composed of a first group refractive element body 421 and a second group refractive element body 422 is arranged on the output side transmission reference surface 402 without any gap is provided.

  Here, the refractive element body 410 of the first focused image generating means 41 is the length of each side of the equilateral triangle that is the bottom surface of the triangular pyramid (side where the inclined refracting surfaces A, a, B, b, C, and c rise). The refractive element body 420 of the second condensed image generating means 42 has sides of a regular triangle that is the bottom surface of the triangular pyramid (sides on which the inclined refracting surfaces A, a, B, b, C, and c rise). ) Is X2, and the side length X1 of the bottom surface of the refractive element 410 is larger than the side length X2 of the bottom surface of the refractive element 420 (X1> X2). In other words, the refractive element body 410 constituting the first condensed image generating means 41 provided on the incident surface is larger than the refractive element body 420 constituting the second condensed image generating means 42 provided on the exit surface. The number of refracting element bodies 410 arranged per area is smaller than the number of refracting element bodies 420 arranged.

  The inclined refracting surfaces A, a, B, b, C, and c in the refractive element body 410 of the first focused image generating means 41 are all isosceles triangles having the same shape, so that the first to third aligned arrangements are made. It is assumed that the lines appear at equal intervals, and similarly, the inclined refracting surfaces A, a, B, b, C, and c of the refractive element body 420 of the second condensed image generating unit 42 are all isosceles triangles (a pair of identical shapes). In this case, the first to third aligned arrangement lines appear at equal intervals. However, the refractive element body 410 of the first condensed image generating means 41 and the refractive element body 420 of the second condensed image generating means 42 do not have a similar shape, and the protrusions in the refractive element body 410 of the first condensed image generating means 41 The height H1 is the same as the protrusion height H2 in the refractive element body 420 of the second condensed image generating means 42 (H1 = H2), and the refractive element body 410 is slightly flattened compared to the refractive element body 420. .

  Specifically, the ratio between the equilateral triangle that is the bottom surface of the refractive element body 410 in the first condensed image generating means 41 and the equilateral triangle that is the bottom surface of the refractive element body in the second condensed image generating means 42 is appropriately set. By setting, when the protrusion height of the first condensing image generating unit 41 on the refractive element body 410 is H1, the inclined refractive surface A and the inclined refractive surface of the refractive element body 410 of the first condensed image generating unit 41 are set. The angle αa formed by a, the angle αb formed by the inclined refracting surface B and the inclined refracting surface b, and the angle αc formed by the inclined refracting surface C and the inclined refracting surface c become 120 degrees, respectively. When the protrusion height in the body 420 is H2, the angle αa formed by the inclined refracting surface A and the inclined refracting surface a in the refractive element body 420 of the second condensed image generating means 42, the inclined refracting surface B, and the inclined refracting surface b. The angle αb formed and the formation of the inclined refractive surface C and the inclined refractive surface c. Each angle αc was set to 90 degrees.

  Further, both the first condensed image generating means 41 and the second condensed image generating means 42 have first to third aligned arrangement lines appearing at equal intervals. The alignment direction of the first group refractive element body 411 and the second group refractive element body 412 is different from the alignment direction of the first group refractive element body 421 and the second group refractive element body 422 in the second condensed image generating means 42; The direction in which the high luminance region occurs in the first condensed image is different from the direction in which the high luminance region occurs in the second condensed image. In the refracting member 40 shown in FIG. 12, the alignment arrangement line in the first condensed image generating means 41 is inclined 45 degrees clockwise with respect to the alignment arrangement line in the second condensed image generating means 42. . When the light of the light emitting source 43 is irradiated from the incident surface of the light refracting member 40 configured in this way, as shown in FIG. 12A, a second condensed image 423 having a complex left and right light emission form is formed on the emission surface side. appear.

  As described above, the shape of the inclined refracting surfaces of the refractive element bodies of the first condensed image generating means and the second condensed image generating means, the inclination angle, the direction in which they are arranged, and the like can be changed in various ways. A second condensed image can be obtained. For example, as shown in FIGS. 13A1 and 13A2, the projecting end of the quadrangular pyramid-shaped refracting element 211 (or the refracting element 221) in the photorefractive member 20 of the first embodiment is cut out and incident. If the refractive element body 211 '(or the refractive element body 221') having a top plane substantially parallel to the side transmission reference plane or the emission side transmission reference plane is used, it is transmitted through the top plane without being refracted by the inclined refractive surface. Since light is also generated, the shape change of the first focused image or the second focused image can be further diversified. Similarly, as shown in FIGS. 13B1 and 13B2, the protruding end of the triangular pyramid-shaped refractive element body 310 (or the refractive element body 320) in the photorefractive member 30 of the second embodiment is cut out. A refractive element 310 '(or a refractive element 320') having a top plane substantially parallel to the incident-side transmission reference plane or the emission-side transmission reference plane may be used.

  Furthermore, in the photorefractive members of the above-described embodiments, the transparent sheet member in which the flat incident-side transmission reference surface and the emission-side transmission reference surface are parallel is used, but the present invention is not limited to this. For example, the light refracting member 50 shown in FIG. 13C is provided with the first condensed image generating means 510 in which the refractive element bodies are arranged in alignment on the incident side transmission reference concave surface 501 that is recessed in the curved shape of the concave lens member 500. FIG. 13D shows a concave surface and an output concave surface provided with second condensed image generation means 520 in which refractive element bodies are arranged in alignment on the output side transmission reference concave surface 502 that is recessed in the curved shape of the concave lens member 500. The light refracting member 60 shown includes an incident convex surface provided with first condensing image generating means 610 in which refractive element bodies are aligned and arranged on an incident-side transmission reference convex surface 601 bulging into a curved surface shape of the convex lens member 600, and the convex lens member 600. It has an exit convex surface provided with a second condensed image generating means 620 in which refractive element bodies are aligned and arranged on the exit-side transmission reference convex surface 602 bulging into a curved surface. Thus, if the entrance surface and the exit surface are curved, the light emission modes of the first condensed image and the second condensed image can be made more diverse. The photorefractive member may be configured such that the incident surface or the exit surface is a flat surface and the other surface is a concave surface or a convex surface, or the photorefractive member is configured by combining the incident surface and the exit surface with a concave surface and a convex surface. It doesn't matter.

<Other embodiments of lighting device>
As described above, if a photorefractive member that can change the light emission mode in various ways is used, the player's attention can be drawn by the light emission mode. For example, in the special symbol hold display device 1600 shown in FIG. 14 (a) (hold storage display means provided in the vicinity of the variable display device 1500), first to third display portions for displaying the numbers 1 to 3 stored. 1601 to 1603 perform general light emission display in which the light emitting surface is illuminated almost uniformly, and the illumination device using the above-described light refracting members 20 to 60 only for the fourth display unit 1604 showing the memory number 4 (Apparatus equipped with a light emitting source capable of appropriate illumination from an appropriate position behind the light refracting members 20 to 60) is applied, and the reserved memory of the number of balls entering the special start port 1520 is set to the upper limit value (memory number 4). It effectively reports that it has been reached. Further, in the special symbol hold lamp 1570 (holding storage display means provided in the vicinity of the special symbol display 1560) shown in FIG. 14 (b), first to third display units for displaying the numbers 1 to 3 stored. 1571 to 1573 perform light emission display using lamps or LEDs, and the illumination device using the above-described light refracting members 20 to 60 (only behind the light refracting members 20 to 60) is applied only to the fourth display portion 1574 indicating the number of memories 4. Device having a light emitting source capable of appropriate illumination from an appropriate position) is effectively notified that the reserved memory of the number of balls entering the special start port 1520 has reached the upper limit (memory number 4).

<Control block>
Next, each control unit functioning as control means in the slot machine 2100 will be described in detail. FIG. 16 shows details of the main control unit 2300, and FIG. 17 shows details of the sub control unit 2400.

<Configuration of main control unit>
First, the main control unit 2300 of the slot machine 2100 will be described with reference to FIG. The main control unit 2300 includes a CPU 2310 that is an arithmetic processing unit for controlling the entire main control unit 2300, a data bus and an address bus for the CPU 2310 to transmit and receive signals to and from each IC and each circuit, It has the structure described below.

  The clock correction circuit 2314 is a circuit that divides the clock oscillated from the crystal oscillator 2311 and supplies it to the CPU 2310. For example, when the frequency of the crystal oscillator 2311 is 12 MHz, the divided clock is 6 MHz. The CPU 2310 operates by receiving the clock divided by the clock circuit 2314 as a system clock.

  The CPU 2310 is connected to a timer circuit 2315 for setting a monitoring cycle for constantly monitoring the state of sensors and switches, which will be described later, and a transmission cycle of motor drive pulses, via a bus. When the power is turned on, the CPU 2310 transmits the frequency dividing data stored in the predetermined area of the ROM 2312 to the timer circuit 2315 via the data bus.

  The timer circuit 2315 determines an interrupt time based on the received frequency division data, and transmits an interrupt request to the CPU 2310 for each interrupt time. In response to this interrupt request, the CPU 2310 executes monitoring of each sensor and transmission of drive pulses. For example, when the system clock of the CPU 2310 is set to 6 MHz, the frequency division value of the timer circuit 2315 is set to 1/256, and the data for frequency division of the ROM 2312 is set to 44, the reference time for this interrupt is 256 × 44 ÷ 6 MHz = 1. 877 ms.

  Connected to the CPU 2310 are a program for controlling each IC, a lottery data used in the internal lottery of the winning combination, a ROM 2312 storing a reel stop position, and a RAM 2313 for storing temporary data. Has been. Other storage means may be used for these ROM 2312 and RAM 2313, and this is the same in the sub-control unit 2400 described later.

  Further, the CPU 2310 is connected to an input interface 2360 for receiving an external signal, and the medal acceptance sensor 2320, the start lever sensor 2321, and the stop button sensor 2322 (for example, the first button sensor 2322) via the input interface 2360 at every interruption time. 1 stop button sensor 2322a, second stop button sensor 2322b, third stop button sensor 2322c), MAX bet button sensor 2323, ONE bet button sensor 2324, checkout button sensor 2325, reset switch 2326, and medal payout sensor 2327 Is detected and each sensor is monitored.

  Two medal acceptance sensors 2320 are installed in the medal passage connected to the medal insertion slot of the medal insertion block 2133, and detect whether or not a medal has passed. The start lever sensor 2321 detects an operation of the start lever 2135 by the player. The stop button sensor 2322 is installed in each of the stop buttons 2136a to 2136c, and detects the operation of the stop button by the player.

  The MAX bet button sensor 2323 detects that the MAX bet button 2131 has been operated, the ONE bet button sensor 2324 detects that the ONE bet button 2132 has been operated, and each detection output is stored electronically in the RAM 2313. This is used to identify the number of medals that have been used as gaming medals. For example, when the ONE bet button sensor 2324 corresponding to the ONE bet button 2132 becomes H level, the CPU 2310 electronically inserts one stored medal, and the MAX bet button sensor 2323 corresponding to the MAX bet button 2131 When the H level is reached, three stored medals are electronically inserted. When the MAX bet button 2131 is pressed, two coins are inserted when the number of stored medals is two, and one coin is inserted when the number is one.

  The settlement button sensor 2325 detects that the settlement button 2138 has been operated. Upon receiving this, the CPU 2310 drives the hopper motor to pay out the stored medals from the medal payout device (hopper). When the reset switch 2326 is operated after recovery from an error or the like, the specific area of the RAM 2313 is cleared and the normal operation state is restored. The medal payout sensor 2327 is for detecting a medal paid out by the medal payout device and performing an appropriate number of payout controls. Each of the above sensors may be a non-contact type sensor or a contact type sensor.

  The CPU 2310 further has an input interface 2361 and output interfaces 2370 and 3271 connected to the address bus via the address decode circuit 2350. The CPU 2310 transmits and receives signals to and from external devices via these interfaces.

  An index sensor 2328 is connected to the input interface 2361. Specifically, the index sensor 2328 is installed at a predetermined position of the mounting base of each of the reels 2110 to 2112, and becomes H level each time the light shielding piece provided on the reel passes through the index sensor 2328. When detecting this signal, the CPU 2310 determines that the reel has made one rotation, and resets the rotational position information of the reel to zero.

  The output interface 2370 drives a reel motor driving unit 2330 for driving a reel and a hopper motor of a medal payout device (a device for paying out a medal accumulated in a bucket from a medal payout opening 2165. Not shown). A hopper motor drive unit 2331, a game lamp 2340 (specifically, a winning line display lamp 2120, an effect lamp 2129, etc.), a payout number display 2126, a game number display 2127, and a stored number display 2128 is connected.

  In addition, a random number generation circuit 2317 is connected to the CPU 2310 via a data bus. The random number generation circuit 2317 is an increment counter capable of incrementing a value within a certain range based on the clocks oscillated from the crystal oscillator 2311 and the crystal oscillator 2316 and outputting the count value to the CPU 2310. It is used for various lottery processes including the internal lottery. Note that the random number generation circuit 2317 includes, for example, two random number counters (a counter that increments a value from 0 to 65535 using the clock frequency of the crystal oscillator 2311 and a value from 0 to 16777215 using the clock frequency of the crystal oscillator 2316. Counter).

  In addition, an output interface 2371 for transmitting a command to the sub control unit 2400 is connected to the data bus of the CPU 2310.

The CPU 2410 transmits the frequency dividing data stored in the predetermined area of the ROM 2412 to the timer circuit 2415 via the data bus at a predetermined timing. The timer circuit 2415 determines an interrupt time based on the received frequency division data, and transmits an interrupt request to the CPU 2410 for each interrupt time. The CPU 2410 controls each IC and each circuit based on the interrupt request timing.

  Further, the CPU 2410 temporarily stores a ROM 2412 in which commands and data for controlling the entire sub-control unit 2400, backlight lighting patterns and data for controlling various displays, and the like are stored. RAM 2413 is connected via each bus.

  The CPU 2410 is connected to an input / output interface 2460 for transmitting and receiving external signals. The input / output interface 2460 has a backlight 2420 and a RAM 2413 for illuminating the designs of the reels 2110 to 2112 from the back. A reset switch 2421 for clearing the data is connected.

  The CPU 2410 is connected to an input interface 2461 for receiving a main control command from the main control unit 2300 via a data bus. Based on the command received via the input interface 2461, an effect process that excites the entire game. Etc. are executed.

  A sound source IC 2480 is connected to the data bus and address bus of the CPU 2410. The sound source IC 2480 controls sound in accordance with a command from the CPU 2410. The sound source IC 2480 is connected to a ROM 2481 that stores sound data. The sound source IC 2480 amplifies the sound data acquired from the ROM 2481 by the amplifier 2482 and outputs the sound data from the speaker 2483.

  Similarly to the main control unit 2300, the CPU 2410 is connected to an address decoding circuit 2450 for selecting an external IC, and the address decoding circuit 2450 has an output interface for outputting signals to various effect lamps. 2470, an input interface 2461 for receiving a command from the main control unit 2300, an input interface 2471 for inputting a signal from the liquid crystal screen control unit 2500, a clock IC 2424, and a signal to the 7-segment display 2440 The output interface 2472 is connected.
