The detection switch 336 is a switch for detecting a broken piece of the prize ball.

  FIG. 5 is a block diagram showing the configuration of the main control unit 220 and the video control unit 240, and shows the minimum configuration necessary for carrying out the present invention. For this reason, for example, when the game ball B wins a normal winning opening, the description of the configuration and operation for the process of paying out a predetermined number of prize balls is omitted. In the figure, the main control unit 220 includes a CPU 230, a ROM 232, a RAM 234, a communication circuit 236, a music processing circuit 222, an output processing circuit 224, and an input processing circuit 226.

  The CPU 230 controls the entire pachinko machine 100 according to the game control program stored in the ROM 232. The ROM 232 uses an EPROM for cost reduction, but is not limited to this, and an EEPROM or a flash RAM may be used. The control program includes a video command program for instructing the video control unit 240 to display a symbol for display on the special symbol display device 126, a determination program for determining whether it is “winning” or “out of”, and a normal symbol display. Programs such as a symbol display program for displaying a predetermined symbol on the device 124, an accessory control program for controlling the ordinary electric accessory 118, or a big prize opening control program for controlling the big prize opening 132 are also stored. .

  The RAM 234 generally uses a DRAM to increase the access speed, but is not limited to this, and a nonvolatile memory such as an SRAM or a flash RAM may be used. The RAM 234 stores game state signals (including command blocks described later), various data such as a gate counter, an accessory counter, and a jackpot counter, or input / output signals. Among these, the gaming state signal is information for instructing a symbol to be displayed on the special symbol display device 126.

  The communication circuit 236 is a circuit that performs mutual transmission of data with the video control unit 240, and sends transmission data sent from the CPU 230 via the bus 238 to the video control unit 240 through a communication line. Here, the transmission data is data transmitted according to the current game state of the ball game machine, and includes a command block for designating symbols to be displayed on the special symbol display device 126.

  The input processing circuit 226 receives the respective detection signals sent from the detection switches 160, 168, 170, 172, other detection switches, etc., and converts them into data formats that can be processed in the main control unit 220. Then, the data is transferred to the CPU 230 or the RAM 234. The music processing circuit 222 converts it into an analog signal according to ringing data sent from the CPU 230 via the bus 238, sends it to the speaker 320, and outputs sound or plays BGM. Further, the output processing circuit 224 converts the driving signal sent from the CPU 230 via the bus 238 into driving signals for driving the ordinary electric accessory solenoid 162 and the big prize opening solenoid 174, and sends them. Note that each of the above components is coupled to the bus 238.

  Next, the configuration of the video control unit 240 will be described. As shown in the figure, the video controller 240 includes a CPU 250, ROMs 244 and 252, a RAM 246, a video controller 256, a D / A converter 258, and a communication circuit 242.

  The CPU 250 analyzes the transmission data sent from the main control unit 220 through the communication line according to the video control program stored in the ROM 252 and sends necessary command data to the video controller 256 via the bus 254. As with the ROM 232, an EPROM is used for the ROM 252 in order to keep the cost low. However, the present invention is not limited to this, and a storage device such as an EEPROM or a flash RAM may be used. The communication circuit 242 is a circuit that performs the same operation as that of the communication circuit 236, and transmits transmission / reception data to / from the main control unit 220.

  The video controller 256 is one of the conversion means 36, and is a controller for converting into an image signal according to a designated color and displaying it on the special symbol display device 126. It is appropriate to use “TFT-GA” manufactured by AmTEC for the video controller 256. The video controller 256 includes a memory for realizing the video output process. The memory map is shown in FIG. 6 and will be described later. The video controller 256 is connected to a ROM 244, a RAM 246, and a D / A converter 258. Here, the ROM 244 and the RAM 246 are one of storage devices that embody the storage means 32.

  As with the ROM 252 and the like, the ROM 244 uses an EPROM to keep the cost low, and stores a symbol for display according to the gaming state and the like. The ROM 244 is desirably a high-speed accessible one so that symbols can be displayed at high speed. However, the present invention is not limited to this, and a storage device such as an EEPROM or a flash RAM may be used. The RAM 246 uses a high-speed DRAM and has an area for storing at least one symbol information 32a.

  Further, the D / A converter 258 is a signal converter for converting the image signal (specifically, digital video data) sent from the video controller 256 into an analog signal and sending it to the special symbol display device 126. . All of the above components are coupled to the bus 254 except for the ROM 244, the RAM 246, and the D / A converter 258.

  Next, a memory map of a memory provided in the video controller 256 is shown in FIG. 6 and will be described with reference to this. This memory map shows the minimum configuration necessary to implement the present invention. 6A, the memory map 400 is roughly divided into a ROM area 402, a work area 404, a screen table area 406, and a palette table area 408.

  The ROM area 402 stores a video output program for controlling the entire video controller 256. For example, data is set in the screen table area 406 in accordance with command data sent from the ROM 244 via the bus 254. In the work area 404, a logical operation for video output is performed. The work area 404 is an area corresponding to each section (hereinafter, referred to as “display section”) obtained by dividing a screen uniformly (or non-uniformly) into a predetermined number (for example, 6), or a plurality of screens. Is an area for synthesizing and outputting video.

  Further, the screen table area 406 is provided with a plurality of screen tables 410 corresponding to each screen, and designation of data (ie, a symbol number described later) necessary for finally outputting as a video. I do. In this screen table 410, as shown in FIG. 6 (B), each data of the symbol number 412 and the pallet number 414, which are numbers assigned to each symbol information (that is, symbol data as symbol contents), is stored. specify. A palette table 420 in the palette table area 408 is provided corresponding to each screen table 410. As shown in FIG. 6C, the color of the design is designated by color codes 422, 424, 426, and 428. . Note that the designated design color is a color that can be displayed on the special design display device 126 (for example, 4096 colors), and includes a transparent color that allows other screens to be seen through.

  Here, palette numbers (for example, numerical values 1, 2, 3, 4 and English letters a, b, c, d, etc.) are assigned in the order of the color codes 422, 424, 426, 428. Thus, by designating one of the assigned palette numbers with the palette number 414 of the screen table 410, one of a plurality of preset colors can be selected. For this reason, a color that is frequently used among various colors can be set in advance using a color code. Also, by specifying the palette number, it becomes easy to select a necessary design color (color) in a necessary scene.

  Next, specific data (numerical values) designated by the color codes 422, 424, 426, and 428 will be described with reference to FIG. FIG. 7 is a diagram showing the configuration of a color code. FIG. 7A shows a color configuration based on the three primary colors, and FIG. 7B shows a configuration based on color tone and lightness. Respectively.

  In FIG. 7A, the color code 500 includes a red lightness code 502, a green lightness code 504, and a blue lightness code 506. The data specified for each lightness code is a numerical value assigned to each of the stages by dividing the darkest color to the brightest color into a plurality of stages. For example, in the case of expressing 4096 colors, the darkest color level may be set to a numerical value “0” and the range up to the brightest color may be divided into 16 levels. At this time, if a numerical value “7” is designated as the red lightness code 502, a numerical value “7” is designated as the green lightness code 504, and a numerical value “0” is designated as the blue lightness code 506, the light yellow green (yellowish green) (Intermediate brightness) is expressed. Similarly, for each of the three primary colors, 32768 colors can be expressed if divided into 32 levels, 262144 colors can be expressed when divided into 64 levels, and 16777216 colors can be expressed when divided into 256 levels. Can be expressed. In this way, the number of colors that can be expressed is greatly increased by increasing the number of divisions, and the colors are also continuous.

  Further, instead of the method of configuring based on the above three primary colors, the configuration may be based on color tone and lightness, and the configuration will be described. In FIG. 7B, the color code 510 is composed of a lightness code 512 and a tone code 514. Here, the data specified for the lightness code 512 is a numerical value assigned to each of the stages, dividing the darkest color to the brightest color into a plurality of stages, like the redness lightness code 502 and the like. Further, the data specified for the color code 514 is a numerical value assigned to each stage by dividing the color tone into a plurality of stages. As the color tone in this case, it is appropriate to apply a color tone ring in which the colors continuously change cyclically in the order of [red-orange-yellow-green-blue-indigo-purple]. In this way, one color tone can be selected from among the color tones that change substantially continuously. The target color tone is not limited to the above color tone ring, but is necessary for display such as visible light spectrum, color temperature (temperature measured by the color of the light source compared with the color of the black body radiation), etc. It is also possible to apply a color tone having a color.

  For example, in the case of expressing 4096 colors, the darkest color is set to a numerical value “0”, the lightest color is divided into 16 levels, and a numerical value is assigned to each level. In this way, as with the color tone, one brightness can be selected from the brightness that changes almost continuously. The color tone is divided into 256 levels, and a numerical value is assigned to each level. At this time, if the numerical value “7” is specified as the lightness code 512 and the numerical value assigned to the intermediate color of yellow and green is specified as the tone code 514, a dim yellow-green color can be expressed as in the case of the configuration of the three primary colors. .

  Next, symbol data stored in the ROM 244 as the storage means 32 will be described with reference to FIG. FIG. 8 is a diagram showing the configuration of symbol data 600, 610,..., 6n0. In the figure, each symbol data of symbol data 600, 610,..., 6n0 is information (digital data) embodied in symbol information 32a, and symbol number data 602 and pixel data (pixel data, other Is also referred to as “bitmap data.”) 604. The symbol number data 602 stores a symbol number, and this symbol number is a unique number assigned corresponding to the content of the symbol displayed on the special symbol display device 126. The pixel data 604 has a predetermined shape area (for example, a rectangular area of 240 pixels wide × 416 pixels long) for storing the contents of the design, and one pixel 606 is made up of 1-bit data.

  Thus, the contents of the symbol stored in the pixel data 604 and the color code specified by the palette number 414 of the screen table 410 (specifically, the color codes 422, 424, 426, and 428 specified by the palette table 420). By any one of the above, it is possible to display various symbols on the symbols on the special symbol display device 126.

  Next, software (processing procedure) for realizing the present invention in the pachinko machine 100 having the hardware configuration as described above will be described with reference to FIGS. Here, FIG. 9 is a flowchart showing a processing procedure for carrying out the present invention. In these processing procedures, the processing shown in steps S10 to S12 in FIG. 9 is realized by the CPU 230 executing the game control program stored in the ROM 232 of the main control unit 220 shown in FIG. For example, it is executed by time division processing every 1 millisecond).

  9 is realized by the CPU 250 executing the video control program stored in the ROM 252 of the video control unit 240 shown in FIG. These series of processes are executed each time a new symbol is displayed on the special symbol display device 126, and the same symbol is continuously displayed until the next execution.

  In FIG. 9, there may be a need to display symbol information on the special symbol display device 126 due to a change in gaming state (for example, the game ball B passes through the gates 116 and 130). In this case, first, the main control unit 220 sets a command block to be sent to the video control unit 240 (step S10). The specific contents of this command block will be described with reference to FIG.

  FIG. 10A shows an example of the command block 700. This command block 700 is a fixed-length data block, and is composed of elements 702, 704, 706, 708, ..., 710, 730. The command block 700 is not limited to a fixed length, and may be a variable length data block. In this case, it is necessary to give the length of the block as one element content, or to make a data string that can recognize the last end of the block.

  Here, in the elements 702, 704, 706, 708,..., The number of the symbol data to be displayed (that is, the symbol number) is designated corresponding to each display section of the display screen of the special symbol display device 126. Each display section is assumed to be fixed in advance with the display area corresponding to the order of the elements. The element 730 stores a value obtained by summing the contents of each data designated by the elements 702, 704, 706, 708,. With this element 730, it is possible to check whether the command block 700 is normally transmitted from the main control unit 220 to the video control unit 240.

  The content specified in the element 710 is information (status) for transmitting the current state on the main control unit 220 side to the video control unit 240 side, and an example thereof is shown in the status list 710a of FIG. Specifically, the element 710 has a fixed data length of 8 bits, and is composed of three types of data.

  That is, as shown in FIG. 10B, the most significant bit 714 (D7) is data indicating the current probability state, and the middle bit 716 (D6 to D4) is the current gaming state 712 on the main control unit 220 side. The data indicating the display content 720 is stored in the lower bits 718 (D3 to D0). More specifically, as the most significant bit 714, for example, “1” is designated for a high probability and “0” is designated for a normal probability. Also, as the gaming state 712, “0” is specified when the power is turned on, “1” when the symbol fluctuates, “2” when reaching in the symbol variation, “3” when jackpot, and “4” when fraud occurs To do.

  Further, as the display contents 720, when the game state 712 is when the symbol changes, “0” is specified when the special symbol is stopped, and “1” is specified when the special symbol is changed. In this manner, the element 710 can transmit that the content of the symbol optimal for the current gaming state is displayed by transmitting the current state on the main control unit 220 side to the video control unit 240 side.

  Returning to FIG. 9, when the command block 700 is set in step S10, it is transmitted to the video controller 240 (step S12). The command block 700 (particularly, the checksum of the element 530) preferably includes an error correcting code (ECC) in order to correct data errors due to transmission errors. Examples of such error correction codes include a cyclic Hamming code, a BCH code (Bose-Chaudhuri-Hocquenghem Code), and a Reed-Solomon code. With this correction code, even when a data error occurs due to, for example, impulse noise when the command block 700 is transmitted, the error is corrected. For this reason, since display with erroneous data is prevented, reliability is improved.

  When receiving the command block 700 (step S20), the video control unit 240 sets the data table according to the contents specified in the transmitted command block 700 (step S22). This data table setting is necessary for the screen table 410 and the pallet table 420 shown in FIG. 6A in order to appropriately display the symbols specified by the elements 702, 704, 706, 708,. Set the correct data. Thereafter, symbol information is set (step S24). Specifically, according to the symbol number designated by the elements 702, 704, 706, 708,... Of the command block 700, specifically, the symbol data 600, 610,... Stored in the ROM 244 shown in FIG. 6n0, the symbol data that matches the symbol number 412 of the screen table 410 shown in FIG. 6B is transferred to each predetermined area partitioned in the RAM 246.

  Then, screen display is performed (step S26). That is, the video controller 256 adds an image signal (specifically) to the symbol data of each display section stored in the RAM 246 shown in FIG. 5 according to the contents of the screen table 410 and the palette table 420 set in step S22. Specifically, digital video data) is output. Thus, the image signal is converted into an analog signal by the D / A converter 258, sent to the special symbol display device 126, and displayed.

  For example, as shown in FIG. 8, when symbol data 600 (more specifically, symbol number 602) in which a symbol representing the English letter “A” is set is specified in the element 702 of the command block 700, First, in step S22, the palette number of the screen table 410 is set according to the status 710. Here, it is assumed that the color specified by the color code of the set pallet number is the above-described dark yellow green color. Accordingly, the pixel data is set so that the alphabet “A” is displayed in the predetermined display section on the display screen by executing step S24, and the dark yellow-green alphabet ““ is displayed on the special symbol display device 126 by executing step S26. A "is displayed. That is, one symbol data can be attached to one symbol data and displayed on the special symbol display device 126.

  In this way, since a symbol with an intermediate color such as reddish green or greenish blue can be displayed, a variety of colors can be expressed on the display screen of the special symbol display device 126. When it is necessary to simultaneously express a plurality of colors on one display screen in the special symbol display device 126 as in “blur”, a plurality of corresponding symbol data 600, 610,. The controller 256 may synthesize and display the video. In this case, it is necessary to set a color code for realizing “blurring” corresponding to each of the symbol data 600, 610,..., 6n0.

  Next, in the method for designating the symbol and the color attached to the symbol as described above, a method for designating the color of another symbol will be described with reference to FIG. First, as a structural premise, as shown in FIG. 11A, a display unit that can be controlled on the display screen 800 of the special symbol display device 126 is a dot (pixel) 802. For this reason, a different (or the same) color among the colors that change substantially continuously can be assigned to each dot 802.

  A unit for each rectangular area or circular (including arc) area in which a plurality of dots 802 are gathered is a character 804, which corresponds to the symbol data described above. Each character 804 is assigned a unique number (character code). Further, the example of the character 804 shown in the figure shows a case where the character 804 is constituted by a rectangular area of 3 dots × 3 dots. Further, one unit in which a predetermined number of characters 804 are assembled is a sprite 806, and the unit can be freely moved (panned) on the display screen 800 in this unit.

  A character table 810 shown in FIG. 11B sets a color (color) assigned to each character 804. The character table 810 is provided with a character code column 812 and a palette number column 814. In the character code column 812, a character code is set for each character 804, and in the palette number column 814, a color palette number assigned to the character 804 specified in the character code column 812 is set. Further, specific colors corresponding to the palette numbers are set in the palette table 820 as shown in FIG. This palette table 820 is provided with a palette number column 822 and a color code column 824. Numbers (numerical values) are sequentially set in the palette number column 822, and the above-described color codes 500, 510, etc. are set in the color code column 824.

  In this way, by gradually setting specific data, the color of the character 804 corresponding to a predetermined symbol unit (symbol portion) can be set continuously and in detail. Although the palette number set in the palette table 820 is set in the palette number column 814 of the character table 810, a color code may be directly set. In this case, since the pallet table 820 is not necessary, the capacity of the RAM 246 (storage means 32) can be reduced. As a result, the cost of the pachinko machine 100 can be kept low.
