Description

  The present invention relates to a structure of a segment indicator used in a gaming machine and a control method thereof.

  In pachinko machines and other gaming machines, various symbols are displayed in order to enhance the effect during the game. As one of the displays for performing this display, a segment display that displays numbers and the like in combination of a plurality of segments is used. In the segment display, each segment includes a lighting unit such as an LED, and one of the anode and the cathode of each lighting unit is connected to a common signal line, and the other is connected to an individual signal line. The common signal line is a signal line common to a plurality of lighting sections, and the individual signal line is a signal line unique to each lighting section connected to one common signal line. When a large number of lighting parts are used, the lighting parts are often divided into a plurality of groups, and the lighting parts are often connected to individual common signal lines for each group. In such a configuration, the common signal lines are used by the number of groups.

  In the segment display, by turning on / off individual signal lines while the common signal lines are turned on, the lighting states of a plurality of lighting sections can be controlled simultaneously. By sequentially switching the common signal lines that are turned on, dynamic lighting control, that is, lighting control that switches the lighting unit to be controlled in units of lighting units connected to each common signal line is realized. As described above, when the common signal lines are provided in units of groups, the lighting state of each group can be controlled relatively easily by switching the common signal lines. When the common signal line is switched at a sufficiently short interval, it is visually recognized as if one symbol is displayed in all segments due to an afterimage effect given to human vision. As an application example of dynamic lighting control, there is a technique described in Patent Document 1.

  As for the segment display, a technique for expressing multiple gradations in each lighting section has been proposed in order to improve the production effect (Patent Document 2). In this technique, in a predetermined unit period (hereinafter referred to as “cycle”), a multi-gradation is expressed by controlling a period during which each lighting unit is turned on, that is, a duty. The number of gradations that can be expressed changes according to the on / off control unit (hereinafter referred to as “frame”) of the lighting unit. For example, if one cycle is composed of 8 frames, 9 gradations can be expressed from the fully extinguished state to the fully lit state, and if composed of 16 frames, 17 gradations can be expressed.

Japanese Patent Laid-Open No. 2003-010457 JP 2003-126371 A

  For gaming machines, there is a need for further improvements in production effects. Regarding the display device, it is required to further increase the number of colors and gradations that can be expressed. The increase in the number of colors is realized by increasing the number of lighting sections, and the increase in the number of gradations is realized by increasing the number of frames.

  However, in general, the length of a frame and one cycle are limited by control processing or hardware, and therefore, when the number of frames increases, the length of one cycle tends to increase. Even when the number of common signal lines increases, it is necessary to perform lighting control while sequentially switching the common signal lines to be turned on, and therefore, the length of one cycle tends to become longer. As a result, the afterimage effect in the dynamic lighting control is weakened, and flickering of each segment becomes easy to be visually recognized when viewed on the entire display, or the luminance of each color is not stable, and as a result, the color balance may be biased. .

  An increase in the number of colors and the number of gradations means an increase in the amount of data for controlling them. The amount of data that can be handled is limited due to hardware limitations of the gaming machine, and the number of colors and gradations that can be expressed is limited. An object of the present invention is to provide a technique capable of alleviating these adverse effects and improving the expressibility of a segment display device used in a gaming machine.

  The display device for gaming machines of the present invention has a display device composed of a plurality of lighting sections. This display device is provided with a common signal line commonly connected to a plurality of lighting sections and individual signal lines for controlling on / off of each lighting section. The common signal line and the individual signal line are connected to a drive circuit that controls these voltages and lights the display. This drive circuit executes control for simultaneously turning on a plurality of common signal lines at least at one timing of lighting control.

  By simultaneously turning on a plurality of common signals in this way, it is possible to turn on all the common signals sequentially and relatively shorten the time required for one round. As an example, consider the case where there are four common signals. The time required for one cycle is half of the time required for sequentially turning on one common signal when two common signals are turned on simultaneously. Thus, by shortening the time required for one round, flickering of the lighting part in dynamic lighting control can be suppressed.

  On the other hand, even if the time required for one cycle is limited to a range in which no flicker is felt, it is possible to sufficiently secure the time for turning on each common signal. As a result, it is possible to ensure a long time during which each lighting unit is lit, and thus there is an advantage that it is possible to ensure brightness even with a low current lighting unit.

  When the display device includes a display device having multicolor lighting portions, lighting portions of various colors can be connected to one common signal line. It is not necessary for one common signal line to have the same color combination, even if the color combination of the lighting part connected to some common signal lines is different from other common signal lines. Good. In such a case, the driving circuit may perform control to turn on at least two common signal lines that are different in color combination (hereinafter simply referred to as “different colors”) at least at one time of lighting control.

  Thus, if lighting control of two or more common signal lines of different colors is performed simultaneously, a color balance between the different colors can be ensured. That is, when displaying a pattern with a combination of LEDs of different colors, it is possible to synchronize the intensity of the afterimage given to the sight by synchronizing the two, and it is possible to visually recognize a hue close to the designed hue. .

  In the present invention, at least two or more common signal lines may be provided which have a common combination of colors of the connected lighting portions (hereinafter referred to as “common colors”). In this case, the drive circuit may execute control to turn on at least two common signal lines of common colors at different timings at least at one timing of lighting control. For example, consider a case where the lighting sections of groups A and B are connected to two common signal lines A and B. Groups A and B include lighting portions of the same color. As a control mode in such a case, a mode in which the common signal lines A and B are alternately turned on and the groups A and B are alternately lit, and a mode in which both are turned on at the same time and the groups A and B are simultaneously lit are considered. . In the latter mode, the change in brightness between lighting and extinguishing is severe. On the other hand, in the former, since one of the groups A and B is always lit, the variation in brightness is relatively small. In the present invention, if the former control mode is adopted, it is possible to suppress variations in brightness for the common color.

  Contrary to the above-described aspect, control for simultaneously turning on the common signal lines of the common colors may be executed. By doing so, since the entire common color is lit in synchronism, color unevenness between parts using the common color is reduced. This aspect is highly useful when the common color lighting parts connected to different common signal lines are relatively close to each other.

  In the present invention, the common signals of different colors may be always turned on at the same time, or may be turned on simultaneously only at a specific time during display control. The common signal that is turned on at the same time may be fixed or changed through display control. As an example of the latter, if it is varied according to the symbol to be displayed, the common signal can be controlled with a combination suitable for expressing the hue of the symbol, and the effect of the presentation can be further improved.

  The present invention may be configured such that a display control device that controls lighting of a display and a drive circuit are directly connected, and a relay circuit is interposed between them. In such a configuration, the number of data signal lines (hereinafter, these data signal lines are collectively referred to as “ports”) provided for the display control device to output control data used to control the display unit is determined as individual signals. Useful when there are fewer lines. The relay circuit is provided with a plurality of latch circuits connected to the data signal lines and the individual signal lines so that the latch circuits that can receive the control data can be sequentially switched in accordance with an instruction from the display control device. From the display control device, the control data is transmitted in a plurality of times while sequentially switching the latch circuits. As a result, the control data to be output to each individual signal line can be held by the entire latch, so that the port of the display control device can be apparently increased by the relay circuit, which is necessary for the control of the display device. A large amount of data can be output. Therefore, it is possible to increase the number of colors and the number of gradations of the display, and the effect of production can be improved.

  In the present invention, it is possible to apply a method of controlling the gradation of lighting of each lighting unit by controlling the lighting duty of each lighting unit within a predetermined unit period (hereinafter referred to as “cycle”). The lighting duty can be controlled, for example, by switching on / off each lighting unit in units of a frame of a certain period set by dividing one cycle. In the present invention, as described above, since it takes a relatively short time to turn on all the common signal lines, it is possible to increase the number of frames in one cycle and realize a wide gradation expression. be able to.

  In order to realize gradation expression by duty control, the display control device sets the gradation of each lighting unit according to the design to be displayed on the display. Then, frame data for controlling on / off of each lighting section in each frame within the cycle period is generated according to this gradation, stored in the buffer memory, and driven at a predetermined timing for displaying the symbol. Output to the circuit. By doing so, it is possible to prepare frame data in advance, so that gradation expression can be realized smoothly.

  A plurality of buffer memories are preferably provided in parallel. In this way, among the plurality of provided buffer memories, any one of the buffer memories can write the frame data while data is being output from any one of the buffer memories to the drive circuit. After the writing is completed, data can be output from the buffer memory to the driving circuit, and new frame data can be written in any other buffer memory. As described above, by using a plurality of buffer memories while sequentially switching between output and writing, frame data can be set and output smoothly.

  In the dynamic lighting control, N common signal lines having different ON / OFF timings can be generated (N is a natural number). Accordingly, each lighting unit is controlled to be turned on / off in units of a period obtained by dividing the frame into N equal parts. In order to execute this control smoothly, the above-described buffer memory may be divided into N areas, and frame data may be read from the corresponding areas according to whether the common signal line is turned on or off.

  Lighting control and frame data generation can be executed at various timings. For example, lighting control is performed by a short-term interrupt process periodically generated every fixed period constituting a frame or a period obtained by dividing the fixed period by an integer, and generation of frame data is periodically generated every unit period. You may make it perform by a long-term interruption process. This means that generation of the next frame data is completed before the gradation expression by ON / OFF in units of frames is completed. In this way, smooth display control can be realized.

  For example, consider a case where a 2 ms frame is defined by dividing a unit period of 16 ms into 8 equal parts. The long-term interrupt process is executed every 16 ms. Each 2 ms frame is further divided into two equal parts, and switching control is performed such that some common signal lines are “ON → OFF” and other common signal lines are “OFF → ON”. In order to realize this switching control, the short-term interrupt process is executed every 1 ms. Under such a setting, it is possible to control the display smoothly by generating data for 8 frames during an interval in which the long-term interrupt processing is executed, that is, 16 ms.

  The present invention can be used for various displays. In a display device having a full-color lighting unit in at least one place, the number of colors to be controlled increases, and thus the utility of the present invention is particularly high. The full-color lighting section normally has three built-in lighting sections of red (R), green (G), and blue (B). These three colors are connected together to one common signal line. To do. In the present invention, the full-color lighting unit is collectively controlled by one common signal.

  The indicator of the present invention may display a symbol by a plurality of display segments as follows, for example. This display device is provided with an LED substrate on which a segment LED for emitting and displaying a display segment and a background LED for emitting and displaying a background surface of the display segment are mounted. This LED substrate is accommodated in a substrate box. In addition to segmenting the segment LED light and the background LED light, there is provided a cylindrical partition member that segments the segment LED light into a plurality of display segments and projects the light forward.

  According to such a display, the display segment is emitted and displayed by the light of the segment LED, and the symbol display is performed, while the background surface of the display segment is emitted and displayed by the light of the background LED separated from the light of the segment LED by the partition member. be able to. For this reason, the background surface of a display segment can be light-decorated and by extension, the visual interest in a symbol display can be improved.

  The present invention does not necessarily have all the various features described above, and some of them may be omitted or combined as appropriate. In addition to the configuration as a display device for gaming machines, the present invention may be configured as a control method for such a display device. Further, the present invention can be configured as a computer program for realizing such control by a computer and a computer-readable recording medium on which the computer program is recorded. Further, the present invention may be configured as a gaming machine using a game board and the display device described above.

Embodiments of the present invention will be described in the following order. In the present embodiment, a configuration as a pachinko machine is illustrated, but the present invention is not limited to this and can be applied to various gaming machines such as a spinning-type gaming machine.

D. Lighting control processing:
E. Production unit composition:

A. Control circuit configuration:
FIG. 1 is a block diagram showing a control circuit configuration of a gaming machine as an embodiment. In this embodiment, the operation of the gaming machine is controlled by distributed processing of each control board such as the main control board 1000, the payout control board 200, the sub-control board 300, and the like. Each control board is configured as a one-chip microcomputer having a CPU, RAM, ROM, etc. therein, and implements various control processes in accordance with programs recorded in the ROM.

  In the gaming machine of the embodiment, the input from the outside to the main control board 1000 is restricted in order to prevent various frauds. As shown in the figure, the main control board 1000 and the sub control board 300 are connected by a parallel electric signal, and the main control board 1000 and the payout control board 200 are connected by a serial electric signal because of the necessity of control processing. . The payout control board 200 and the sub control board 300 operate in accordance with commands from the main control board 1000, respectively.

  When a ball enters a winning slot provided on the game board surface based on the control of the main control board 1000, the pachinko machine pays out the ball, makes a hit / loss judgment based on a random number, and if it is determined to be a win Operates to release the special winning opening provided on the game board surface for a predetermined period. In order to realize the operation during the game, the detection result of the winning detector 1001 for detecting the winning of the ball at the winning opening is inputted to the main control board 1000. Further, the main control board 1000 outputs a control signal for the special prize opening solenoid 1002 for releasing the special prize opening.

  A symbol display LED 1003 is also connected to the main control board 1000. The symbol display LED 1003 is composed of 16 LEDs, and performs display called normal symbol, special symbol, normal symbol hold, and special symbol hold according to the winning state during the game. The main control board 1000 directly controls the lighting state of the symbol display LED 1003.

  Control of each operation during other games is performed via the payout control board 200 and the sub control board 300. The payout control board 200 controls the launching and payout of the ball being played in the following procedure. The launch of the sphere is controlled directly by the launch control board 202. That is, when the player operates the launch handle 201, the launch control board 202 controls the launch motor 203 to launch a ball. The payout control board 200 indirectly controls the launch of the sphere by sending a launch control signal to the launch control board 202.

  When a command indicating that a prize has been won during the game is received from the main control board 1000, the payout control board 200 controls the payout motor 220 and pays out a specified number of balls while counting the number of balls. The payout control board 200 detects whether or not the balls stored for payout are insufficient by the ball break switch 210, and outputs a ball shortage detection signal to the sub control board 300 via the main control board 1000 when there is a shortage. The sub-control board 300 receives this detection signal and lights a predetermined part of the frame decoration lamp 330.

  The sub control board 300 controls effects such as voice, display, and lamp lighting during the game. These effects vary according to the status during the game, such as during normal times, when winning a prize, or when winning a big hit. When an effect command corresponding to each status is transmitted from the main control board 1000, the sub control board 300 activates a program corresponding to each command to realize the effect instructed from the main control board 1000. .

  In the present embodiment, the sub-control board 300 directly controls the speaker 310 as shown in the figure. A plurality of speakers 310 may be connected. As the display, a frame decoration lamp 330, a design lamp 370, and a panel decoration lamp 390 are provided. In this example, LEDs were used for these lamps. The frame decoration lamp 330, the design lamp 370, and the panel decoration lamp 390 each represent a set of a plurality of LEDs arranged on the substrate.

  The frame decoration lamp 330 is connected to the sub-control board 300 via the lamp relay board 320 and is controlled to be lit statically in accordance with a control signal from the sub-control board 300. As will be described later, the symbol lamp 370 is a display unit composed of a plurality of segments, and is used to display a decorative symbol associated with the symbol display LED 1003. The symbol lamp 370 is connected to the sub-control board 300 via the lamp driving board 350, and each LED is controlled to be dynamically lit according to a signal from the sub-control board 300. The symbol lamp 370 corresponds to the display device in the present invention.

  The panel decoration lamp 390 is a display for decorating the periphery of the symbol lamp 370. The panel decoration lamp 390 is connected to the sub-control board 300 via the lamp driving board 350, and each LED is statically controlled to light according to a signal from the sub-control board 300. A unit including the design lamp 370 and the panel decoration lamp 390 is referred to as an effect unit.

  The control circuit configuration described above is an example of a gaming machine. The connection destination of each hardware module is not limited to the illustrated example, and various configurations can be adopted. Further, a configuration in which a part of the illustrated hardware module is omitted or a configuration in which a separate hardware module is added may be employed depending on the function required for the gaming machine.

B. Lamp drive board and design lamp:
FIG. 2 is an explanatory diagram showing the internal structure of the sub-control board 300 and the lamp driving board 350. Only the portion related to the connection of the design lamp 370 and the panel decoration lamp 390 is shown. The frame decoration lamp 330 is connected to the CPU 302 by a circuit different from that shown in the figure.

  The lamp driving board 350 is provided with eight latches 352 [1] to 352 [8] in parallel. Each latch can hold 8-bit data. The latch 352 [8] is connected to the panel decoration lamp 390, and the latch group 354 including the other latches 352 [1] to 352 [7] is connected to the symbol lamp 370 as a whole. Signals connected to the symbol lamp 370 include a common signal 376 and individual signal lines 377 used for dynamic lighting control of the symbol lamp 370. Details of these signals will be described later.

  The connection between the latch 352 and the design lamp 370 and the panel decoration lamp 390 is not limited to the illustrated example. For example, a part of the data lines of one latch 352 may be connected to the panel decoration lamp 390 and the rest may be connected to the symbol lamp 370.

  The lamp driving board 350 is connected to an output port from the CPU 302 of the sub control board 300. This output port includes eight data lines and a signal line 356 including a select signal for switching the latches 352 [1] to 352 [8]. Data transfer to the latch is not necessarily performed in 8 bits, and can be arbitrarily set to 4 bits. However, the number of bits for data transfer is preferably matched with the number of bits held in the latch. Even if the number of transfer bits is reduced, all data required for control can be transferred by increasing the number of data transfers.

  In the RAM provided in the sub-control board 300, two work areas, buffer memories 304 [1] and 304 [2], are provided for data output. It is output alternately. Each buffer memory 304 is connected to the CPU 302 by a data line 306 or the like.

  Data output from the CPU 302 to the symbol lamp 370 and the panel decoration lamp 390 is performed in the following procedure. The CPU 302 writes control data for controlling display of the symbol lamp 370 and the panel decoration lamp 390 in any of the buffer memories 304. The data written in the buffer memory 304 is transferred to the lamp driving board 350 in 8 steps while switching the select signal, and is sequentially held in the latches 352. When the accumulation of data in all the latches 352 is completed, these data are transmitted from the lamp driving board 350 to the design lamp 370 and the panel decoration lamp 390. Thus, the lamp drive substrate 350 apparently has a function of increasing the number of data lines from the sub-control substrate 300. In this embodiment, the number of data lines can be used up to a maximum of 64 by using eight latches.

  FIG. 3 is an explanatory diagram showing the arrangement of LEDs in the present embodiment. These are the LEDs constituting the interior of the effect unit, that is, the symbol lamp 370 and the panel decoration lamp 390. In this embodiment, red (R), green (G), and blue (B) single-color LEDs and LEDs capable of full-color display by incorporating these three colors are mixedly used. Here, for convenience of describing the following control processing, the internal configuration of the rendering unit will be described first, and the configuration of the entire unit when attached to the gaming machine will be described in detail at the end.

  Frames F1 to F3 surrounded by broken lines are panel decoration lamps 390. Each of the panel decoration lamps 390 is a red (R) single color LED. Frames A to E are symbol lamps 370. A full color LED is used for the frame A. In the frames B and C, red (R) and blue (B) single color LEDs are mixedly used. The LEDs in the frames A to C are incorporated in each of the seven segments that can display the shape of “8”. Red (R) monochromatic LEDs are used in the frames D and E. As described above, the design lamp 370 is dynamically lit. This lighting control is performed by treating the LEDs in each of the frames A to E as one group. Hereinafter, the LEDs in each frame are collectively referred to as groups A, B.

  FIG. 4 is an explanatory diagram showing a circuit configuration of the lamp driving substrate 350 and the symbol lamp 370. Four common signals C12, C11, C22, and C21 are output from the lamp driving board 350, and the LEDs of the group B, group C, group A, group D, and E are connected to each other. The common signals C11 and C12 are provided with individual signal lines S1-1 to S1-14. The blue LEDs Bb1 to Bb7 and the red LEDs Br1 to Br7 in the group B are connected to the individual signal lines S1-1 to S1 to 14, respectively, as illustrated. Similarly, the blue LEDs Cb1 to Cb7 and the red LEDs Cr1 to Cr7 in the group C are connected to the individual signal lines S1-1 to S1 to 14, respectively. The reason why the red LEDs are used in pairs while the blue LEDs are used alone is to match the luminance between the two. Moreover, although illustration was abbreviate | omitted in order to avoid complication of a figure, the resistance for brightness | luminance adjustment is connected to each LED.

  The common signals C21 and C22 are provided with individual signal lines S2-1 to S2-21. The three color LEDs incorporated in Ac1 to Ac7 of full color LEDs in group A are connected to individual signal lines S2-1 to S2-21, respectively. Dr1 to Dr14 of red LEDs of groups D and E are connected to individual signal lines S2-1 to S2-14, respectively. In the groups D and E, the individual signal lines S2-15 to S2-21 are not used. Although not shown, the LEDs for groups A, D, and E are also connected to resistors for brightness adjustment.

  In this circuit configuration, in this embodiment, the common signals C12 and C22 and C11 and C21 are turned on in synchronization with each other. When the common signals C12 and C22 are on, the LEDs of the group B (red LED and blue LED) and the group A (full color LED) are turned on according to the on / off of each individual signal line. . When the common signals C11 and C21 are on, the LEDs of the group C (red LED and blue LED) and the groups D and E (red LED) are turned on.

  Thus, in the present embodiment, lighting is controlled so that groups having different combinations of LED colors connected to the common signal are simultaneously turned on. By doing this, there is an advantage that it is easy to ensure a color balance between groups that are simultaneously turned on. In the present embodiment, by alternately turning on the groups B and C using LEDs of the same color (red LED and blue LED), these colors (hereinafter referred to as “common colors”) It is possible to realize a state in which the light is always lit at any part. Accordingly, it is possible to suppress the time variation of the brightness of the common color as a whole.

  In the present embodiment, by turning on two common signals at the same time, the LEDs of each group can be lit at a relatively short period in the dynamic lighting control. If only one common signal is used, each group is turned on in the order of group B → group C → group A → groups D and E, which is three times as long as the lighted period. There will be a blank period. Accordingly, each group can secure a lighting period only for a maximum of 25% of the total period.

  On the other hand, when two common signals are used, each group is lit in the order of group B → group C and group A → groups D and E. The blank period can be made equal. Therefore, it is possible to ensure a lighting period of up to 50% of the entire period. As described above, in this embodiment, since the blank period can be shortened, the brightness of the LED can be secured and the flicker at the time of display can be suppressed. By ensuring the brightness of the LED, the power consumption of the LED can be reduced.

C. Gradation control:
FIG. 5 is an explanatory diagram showing a gradation expression method. The lighting control of the LED “Bb2” connected to the common signal C12 is shown as an example. On the left side of the figure, output signals of individual signals S1-3 connected to the common signals C12 and Bb2 are shown. As described above, in this embodiment, the common signals C12 and C11 are alternately turned on / off. A period t1 during which each common signal is turned on is 1 ms. Accordingly, each of the common signals C12 and C11 is turned on / off at a cycle t2 of 2 ms which is twice this. Hereinafter, a section of the period t2 in which the common signals C12 and C11 are turned on / off is referred to as a frame. In this embodiment, each LED is duty-controlled in units of 8 frames, that is, a period of 16 ms. This period of 8 frames is hereinafter referred to as a “cycle”.

  The Bb2 lighting state is shown below the common signal C12 according to the gradation value. When the gradation value is “0”, Bb2 is turned off in all frames during one cycle. In the case of the gradation value “1”, the signal is on (hatched portion in the figure) at one frame. Hereinafter, as the gradation value increases, the number of frames that are turned on increases, and the lightest gradation value “8” is turned on in all frames. In this way, nine levels of gradation can be expressed by increasing the ratio of the period during which the LED is on in the cycle, that is, the duty, as the gradation value increases.

  On the right side of the figure, control data (hereinafter referred to as “frame data”) for realizing gradation expression is illustrated. As shown in the lower part of the figure, one bit is assigned to each LED, and ON / OFF is controlled by this bit string. In the upper right, the control data corresponding to the bits assigned to the LED of Bb2 is shown with gradation values on the horizontal and frame numbers on the vertical.

  When the gradation value is “0”, it is turned off in all the 1 to 8 frames, so “0” is output for all frames. When the gradation value is “1”, only the first frame is on, and the other frames are off. Accordingly, for the gradation value “1”, the bit string “1, 0, 0, 0, 0, 0, 0, 0” of 1 to 8 frames is output in this order. Similarly, the gradation values 2 to 8 are sequentially output so as to be “1” in the portion corresponding to the frame that is turned on and “0” in the other portions. That is, if attention is paid only to the bit number “3”, any of the bit strings described above is selected and output in time series according to the gradation value to be expressed by the LED “Bb2”. Simultaneously with the bit number “3”, the control data of the LED “Bb1” is sequentially output from the bit number “1”, and the control data of the LED “Br1” is sequentially output from the bit number “2”. In this way, when viewed in units of frames, a plurality of bits of data corresponding to all LEDs are output in parallel, but when viewed through 1 to 8 frames in units of bits, an on / off time series that realizes duty control A typical signal will be output.

  FIG. 6 is an explanatory diagram showing a frame data output method. A method of outputting frame data using two buffer memories 304 [1] and 304 [2] provided on the sub-control board 300 has been shown. Each buffer memory 304 schematically shows the frame data to be stored, with the LED name in the horizontal direction and the frame number in the vertical direction. Each buffer memory 304 stores frame data for one cycle (8 frames) for all LEDs.

  As illustrated, the frame data is output from the CPU 302 to the lamp driving board 350 via the two buffer memories 304 [1] and 304 [2]. The CPU 302 can switch the operation of the buffer memories 304 [1] and 304 [2] to the write mode / read mode.

  The CPU 302 first sets the buffer memory 304 [1] to the write mode, and sets the buffer memory 304 [2] to the read mode. At this time, one cycle of frame data is sequentially output from the buffer memory 304 [2] to the lamp driving substrate 350 as indicated by the black arrows in the figure. As described above, this output is outputted in a plurality of times every 8 bits, and sequentially stored in a latch in the lamp driving substrate 350.

  In the present embodiment, as described above with reference to FIG. 5, the common signals C12 and C11 are switched on / off every 1 ms in one frame (2 ms). Similarly, the common signals C22 and C21 are switched on / off. From the buffer memory 304 [2], frame data corresponding to the common signal to be turned on is read in accordance with the turning on / off of the common signal. That is, the first frame data corresponding to the LEDs belonging to the groups B and A is read during the period when the common signals C12 and C22 are turned on, and the group C is read during the period when the common signals C11 and C12 are turned on. The second frame data corresponding to D and E is read out. As a result, at the time of reading, the buffer memory 304 is divided into two areas corresponding to the first and second frame data, and data is alternately read from each area.

  In parallel with this data output, the frame data for the next one cycle is stored in the buffer memory 304 [1] from the CPU 302. Data is read in units of 1 ms, whereas data is stored in units of 16 ms. By doing so, storage of frame data to be used in the next cycle is completed before output for one cycle is completed, and smooth display control can be realized.

  Thus, when the data output from the buffer memory 304 [2] and the data writing to the buffer memory 304 [1] are completed, the CPU 302 switches the operation mode of the buffer memory 304. That is, the buffer memory 304 [2] is set to the write mode, and the buffer memory 304 [1] is set to the read mode. As a result of this switching, new control data is output from the buffer memory 304 [1] to the lamp driving board 350 as indicated by the white arrow in the figure, and the frame data of the next cycle is again output to the buffer memory 304 [2]. Is written by the CPU 302.

  In this embodiment, frame data can be output efficiently by using the two buffer memories 304 alternately in this way. The use of the two buffer memories 304 is not limited to the above-described mode. For example, the buffer memory 304 [1] may be a buffer memory dedicated to writing from the CPU 302, and the buffer memory 304 [2] may be a buffer memory dedicated to output to the lamp driving board 350. In this case, when the data output for one cycle is completed, the data is transferred from the write-only buffer memory 304 [1] to the output-only buffer memory 304 [2], and the frame data of the next cycle is output. And write. Also in this aspect, efficient data output can be realized by using two buffer memories together.

  In the present embodiment, the design lamp 370 is dynamically controlled to light using the frame data described above, while the panel decoration lamp 390 is controlled to be statically controlled. The static lighting control is a control in which the common signal is not switched and is always turned on or off for one cycle. Therefore, the control data for the panel decoration lamp 390 is sufficient to use data for one frame over one cycle. Although not shown in FIG. 6, the buffer memory 304 is also provided with an area for storing control data for the panel decoration lamp 390, and this data is transmitted via the lamp driving board 350 in the same manner as the frame data. It is output to the panel decoration lamp 390.

D. Lighting control processing:
FIG. 7 is a flowchart of control processing in the embodiment. This is a process executed by the CPU 302 of the sub control board 300. However, for convenience of explanation, only processing related to the display of symbols is shown. The left side shows a main loop repeatedly executed by the CPU 302 in a long cycle (16 ms in the present embodiment), and the right side shows a periodic execution executed by interrupting the main loop in a short cycle (1 ms in the present embodiment). The interrupt process was shown. These processes are realized by a long-cycle interrupt process and a short-cycle interrupt process, respectively.

  When the power is turned on and the main loop is started, the CPU 302 executes a predetermined initialization process (step S10) and starts a game loop. In this process, first, a system command transmitted from the main control board 1000 is analyzed (step S12). The system command includes a command for designating a symbol to be displayed.

  In response to this command, the CPU 302 sets a symbol schedule for displaying symbols (step S14). The symbol schedule is data defining the color, gradation, and blinking of each LED according to the symbol type. One symbol is composed of a plurality of cycles. The CPU 302 generates frame data in each cycle in accordance with the symbol schedule set in this way, and stores it in the buffer memory 304 (step S16). At the same time, control data for the panel decoration lamp 390 is also generated and stored in the buffer memory 304. In the main loop, the above processing is repeated during the game.

  In combination with the above-described processing, the periodic interrupt processing is executed with a short cycle of 1 ms. When this process is started, the CPU 302 first clears the common signal of the lamp driving board 350 and turns off all the LEDs (step S20). As a result, it is possible to prevent the LED from blinking irregularly during the rewriting of the individual control signal.

  Next, the CPU 302 outputs frame data for one frame from the buffer memory 304 to the lamp driving substrate 350 (step S22). This data output is performed in a plurality of times every 8 bits as described above. The CPU 302 detects the timing every 16 ms from the start of the periodic interrupt process by updating the 1 ms counter (step S24). If this timing is reached (step S26), the frame decoration frame data is output (step S28), and the periodic interrupt process is terminated. At other timings (step S26), the output of the frame decoration frame data is skipped.

  In this control process, in the main loop executed in a long cycle, not only the gradation value of each LED is set, but also the development to the frame data is completed (step S16). Therefore, the periodic interrupt process does not need to generate frame data, and only needs to output data to the lamp driving board 350, so that there is an advantage that the processing load is very light. In this embodiment, the data output to the lamp driving board 350 is executed in a plurality of times by 8 bits. However, since the processing load in the periodic interrupt processing is light, a large amount of data output can be sufficiently performed in a short cycle. It becomes possible to execute.

  According to the gaming machine of the embodiment described above, it is possible to increase the number of colors and the number of gradations of the display and secure the color balance while effectively utilizing hardware resources, and the possibility of expression during gaming Can be improved.
