[Problems to be Solved by the Invention] However, since this type of inverter board converts direct current to relatively high frequency alternating current, it may oscillate at a relatively high frequency and emit radio waves. There is a drawback that the liquid crystal driver board is adversely affected by the radio waves, causing the liquid crystal driver board to malfunction and causing the liquid crystal display device to no longer be in a normal display state.

[0004] Therefore, it is conceivable to configure this inverter board separately from the liquid crystal driver board, separate the inverter board from the liquid crystal display device, and attach it to an appropriate location of the gaming machine. However, in the case of such a configuration, when assembling it into a gaming machine, the inverter board must also be assembled separately from the liquid crystal display device, which creates a new drawback that the assembly work becomes complicated. Furthermore, noise caused by static electricity is likely to be generated in a gaming hall, and there is a risk that the adverse effects of the noise will affect the liquid crystal driver board, causing malfunctions due to the noise.

The present invention has been devised in view of the above circumstances, and its purpose is to eliminate the adverse effects of radio waves emitted from an inverter board that transmits at a relatively high frequency and the adverse effects of external noise caused by static electricity on liquid crystal displays. To provide a liquid crystal display device which is prevented from reaching a driver board as much as possible, is made relatively compact as a liquid crystal display device, is easy to handle, and is relatively easy to assemble into a game machine.

[Means for Solving the Problems] The present invention is a liquid crystal display device used in a gaming machine, which includes a liquid crystal display portion, and emits light when supplied with alternating current, and irradiates light from the back side of the liquid crystal display portion. a light emitting source that makes it easier to see the display state of the liquid crystal display; a liquid crystal driver board for driving the liquid crystal display; and a liquid crystal driver board that is separate from the liquid crystal driver board. and a conductive plate covering the front side and the back side of the liquid crystal driver board, and the inverter board is integrally provided at a predetermined position outside the conductive plate. It is characterized by

[0007]

[Operation] According to the present invention, since the liquid crystal driver board and the inverter board are constructed separately, and the front and rear surfaces of the liquid crystal driver board are covered with conductive plates, oscillation occurs at a relatively high frequency. The negative influence of radio waves emitted from the inverter board is prevented as much as possible from reaching the liquid crystal driver board, and the noise from the outside is suppressed as much as possible by the conductive plate, so that the negative influence of noise from reaching the liquid crystal driver board is minimized. It can be prevented. moreover,
Since the inverter board is integrally provided at a predetermined position outside the conductive plate, the entire liquid crystal display device is assembled into a compact unit, making it easy to handle.

FIG. 9 is a flowchart showing the main routine of a program for explaining the operation of the control circuit shown in FIG.

This main routine is executed once every time the above-mentioned periodic set pulse is generated once every 2 msec. In step (hereinafter simply referred to as S) 1,
An address to be used as a stack pointer is specified. Next, in S2, it is determined whether or not there is a RAM error. This determination is made, for example, by reading data at a predetermined address in the RAM and determining whether or not the read data is equal to a predetermined value. R.A.
If there is no M error, control proceeds to S4. However, when a program runs out of control or when the power is turned on, a RAM error occurs because the contents stored in RAM are undefined, and control is switched to S3.
Proceed to.

In S3, system initial processing such as setting initial data in the RAM is performed, and then a waiting process is started. During the rendezvous process, a periodic reset pulse is given to the MPU, which resets the system and restarts the main routine from the beginning.

Next, in S4, a switch winning determination is made. This switch winning determination is based on the switch circuit 81
Which switch 8, 9 is selected based on the signal input from
, 10a to 10c are turned on. Based on the determination result, the output from the output port A is processed in S5, and the output from the output port C is processed in S6. This output port A output is the starting winning memory LED 16 (

The control output is for lighting various lamps such as , etc. and for exciting the solenoid 73 for opening the variable winning ball device 4 .

Next, proceed to S7, and set the number of LCD data transfers to 8.
is set. This is because data bits for liquid crystal display control are sent 8 bits at a time to the liquid crystal display driving device 91 (see FIG. 8) when this main routine is executed once.
In S7, "8" is set, and during one execution of this main routine, the transfer control of display data bits from S14 to S20 is repeated eight times. Next, the process advances to S8, and the first driver chip select signal is set. Next, the process advances to S9, where it is determined whether the LCD data counter is between 0 and 6. This LCD data counter is incremented by "1" in S22, which will be described later.
4, and counts how many times the display data bits consisting of 8 bits have been transferred to the liquid crystal display driving device. If the value of the LCD data counter is within the range of 0 to 6, the process proceeds to S11, but if the value of the LCD data counter is 7 to 14, the process proceeds to S10, where the second driver chip select is selected. After the signal is set, the process advances to S11. In other words, the data bits for liquid crystal display consisting of 8 bits are repeatedly transferred from 0 to 13 14 times to the liquid crystal display driving device 91.
The 56-bit liquid crystal display data consisting of the first seven times is given to the first driver, and the second half liquid crystal display data consisting of 7 to 13 times of 56 bits is given to the second driver.

In S11, the boat B output data is set, and the chip select signal set in S8 or S10 is output. Next, proceed to S12,
LCD output data is set. With this S12,
An 8-bit liquid crystal display data bit (see FIG. 10) is set. Next, the process advances to S13, where LCD CE (chip select signal) is set and initialization processing for starting communication is performed. Next, the process proceeds to S14, where one bit of liquid crystal display data bits is transferred to the LCD driver board 41 side. Next, data is selected in S15,
The LCD data is set in S16, the LCD clock is set in S17, the liquid crystal display data bit is latched and read at the rising edge of the clock signal in S18, and the LCD data is updated in S19. The clock signal of S17 is a clock signal generated within the basic circuit 77 (see FIG. 8) described above, and the relationship between the clock signal and the data bits for liquid crystal display is shown in FIG.

In FIG. 10, data bits for liquid crystal display corresponding to each rising point in the clock signal are latched, and the data bits are read and updated as data for liquid crystal display. FIG. 10 shows a diagram at the start of data transfer when the LCD data counter is "0", and at that stage, the first driver chip select signal is set and CE1 is at high level. This CE1 falls and becomes a low level when 8-bit liquid crystal display data is sent seven times and a total of 56 bits of liquid crystal display data is sent. That is, the first
The display control signal to the driver 42a consists of 56-bit liquid crystal display data. Furthermore, after the 8-bit liquid crystal display data bits have been sent seven times, the second driver 42b goes into a high level state.
The 8-bit liquid crystal display data is sent to the second driver 42b seven times, and a total of 56 bits of liquid crystal display data is transferred to the second driver 42b. That is, the second
The liquid crystal display data transferred to the driver 42b is also composed of 56-bit data. Next, the process proceeds to S20, where "1" is subtracted from the number of LCD data transfers set in S7, and the process proceeds to S21, where it is determined whether or not the number of LCD data transfers is "0".
0'', the process returns to S14 again, and the selection and transfer control of the next 1-bit liquid crystal display data is repeated. This selection and transfer control of liquid crystal display data is repeated eight times, and when the 8-bit liquid crystal display data has been transferred, a YES judgment is made in S21, and the process advances to S22, where "1" is set in the LCD data counter. is added. Next, in S23, the value of the LCD data counter is “14”.
It is determined whether or not the value is greater than or equal to 14. If the value is greater than or equal to 14, the value of the LCD data counter is cleared in S24, and then the process proceeds to S25; however, if it is less than 14, the process proceeds to S25. Proceed directly to S25. In other words, the LCD data counter repeatedly counts up values from 0 to 13. In S25, random 1 creation processing is performed, and in S26, random 2 creation processing is performed. The random 1 creation process and the random 2 creation process are processes for determining whether or not the display result when the variable display device 3 is stopped is a jackpot combination of identification information. Specifically, in S25, Set the value of the random 1 counter to “1”
'', and in step S26, the value of the random 2 counter is incremented by 1. Note that the random 1 counter is 0.
The random 2 counter counts up the value from 0 to 22 and starts counting up again from 0 when it reaches 22.The random 2 counter counts up the value from 0 to 9, and when it reaches 9, it starts counting up again from 0. I will upload it again. Next, the process advances to S27, where it is determined whether the number of resets is 1, 3, 2, or 4 by referring to the stacked data. If the number of resets is 1 or 3, the process in S28 is performed and the process advances to S31. On the other hand, when the number of resets is 2, the symbol display data set and sound data control processing is performed in S29, and S31
Proceed to. This symbol display data in S29 is symbol data to be displayed on the variable display device 3, and this
The contents of the symbol display data set by 29 are S1
4 to S21, the data is transferred to the LCD driver 41. As a result, the variable display device 3 performs a display based on the transferred contents, and by switching the contents of this symbol display data according to the gaming state, display control as shown in FIG. 7 is performed. The specific control content of the variable display of this variable display device 3 is that when a pachinko ball starts and wins without any memory of starting winnings, after the basic time (for example, 5 seconds) is displayed variably, the variable display device is turned off. Control is performed to stop it. On the other hand, the starting winning memory is 1
If there is a starting prize in such a case, control is performed to cause the variable display device to display a variable display for a shortened time (for example, 2 seconds) and then to stop the variable display device. This starting winning memory is subtracted by "1" when the variable display device starts changing. In addition, even if there is a starting winning when the starting winning memory is 1 or more, if the starting winning memory is already "0" at the time of the variable start based on the starting winning, the basic time (for example, 5 seconds) ) After the variable display is performed, the control shifts to stop the variable display device.

If it is determined in S27 that the number of resets is "4", the process advances to S30, and after each process of storage LED data control, lamp data control, and sound data control is performed, the process advances to S31. In S31, random 2 creation processing is performed. Further, in S32, a random creation process for symbol display is performed. The processing of S31 and S32 is
A reset pulse is sent from the periodic reset circuit 79 to the basic circuit 7
7 is repeatedly executed using the reset waiting time until the input is made. The specific processing content of S31 is to repeatedly count up the value of the random 2 counter, and the processing content of S32 is to repeatedly count up the value of the random counter for symbol display.

[0052] The determination as to whether or not the display result when the variable display device is stopped is to be a jackpot combination of identification information is made as follows. In other words, the value of the random 1 counter is extracted when the pachinko ball starts winning, the value of the random 2 counter is extracted when the left symbol of the variable display device stops, and the extracted value of the random 1 counter and the random 2 counter are extracted.
A jackpot is determined only when both the counter values are "1". As a result, the probability of hitting the jackpot is
1/23×1/10=1/230. The random 1 counter is incremented by 1 each time this main routine program is executed in S25, while the random 2 counter is incremented by 1 each time the main routine program is executed in S26. Not only is it added, but it is also added repeatedly using the reset waiting time in S31, and since the two addition methods are different, the value of the random 1 counter and the value of the random 2 counter are not synchronized. This avoids clutter and makes jackpot decisions more random.

The symbol display random counter is composed of three counters, one for the left symbol, one for the middle symbol, and one for the right symbol, and each counter is configured to be able to count values from 0 to 15. Then, each time S32 is processed, "11" is added to the left symbol counter, and when the left symbol counter reaches a carry, "1" is added to the middle symbol counter, and the middle symbol is When the counter for the right symbol has carried over, "7" is added to the counter for the right symbol. Then, the value of the counter for the left symbol is extracted when the variable display device starts changing, and as a result of extracting the random 1 counter and the random 2 counter, it is determined that the display result when the variable display device stops is the combination of jackpot identification information. In this case, the middle and right symbols are matched with the symbol corresponding to the value of the extracted left symbol counter, so that the display result when the variable display device is stopped is the same combination of symbols (so-called doublet). to control the stop. On the other hand, if it is decided that the display result when the variable display device stops is a combination of identification information that is out of order, the values of the counters for the middle and right symbols are extracted when the left symbol is stopped, and the values of the counters for the middle and right symbols are extracted when the left symbol is stopped. Based on the value and the value of the left symbol counter extracted at the start of variation, the variable display device is stopped and controlled so that the symbol corresponding to each value is displayed. At that time, if the values of the extracted symbol counters happen to be the same combination of identification information (so-called doublet), if the display is controlled as it is, the display result will be different even though it was determined that the result was a failure. Since the combination of identification information becomes a winning combination, in order to avoid this, the right symbol is forcibly shifted to another symbol and a stop control is performed.

As explained above, in order to serially transfer liquid crystal display data from the game control board to the LCD driver board 41, the electrical wiring connecting the game control board and the LCD driver board 41 is as shown in FIG. It has the advantage of requiring only seven wires, eliminating the need for complicated electrical wiring. The liquid crystal display board 34 is provided with a total of 44 segment display sections, and in order to display one liquid crystal display section consisting of two color liquid crystal sections, green and red, two display signal lines are required. Since 90 signal lines (44×2+2 (common lines for each driver) = 90) are required, the liquid crystal display board 34
It is necessary to connect the LCD driver board 41 and the LCD driver board 41.
