When a hit ball enters the first-type starting port 4, the display screen of the symbol display device 6 in which three rows of symbols are scrolled in the vertical direction and fluctuates, and a predetermined same symbol is displayed. When the player stops in line, a jackpot is won and the special winning opening 5 is opened, and when a predetermined time elapses, or when a predetermined number of hits enter the special winning opening 5, the opening of the special winning opening 5 is performed. Stop.

Reference numeral 8 is a representative representation of a plurality of display lamps provided on the panel surface 1. The display lamps 8 are turned on and off when a predetermined condition is reached during a game. Reference numeral 9 denotes a sound generator which generates a predetermined sound when a predetermined condition is satisfied during a game.

In order to determine a stopped symbol after scrolling in the symbol display device 6 described above, a predetermined calculation process is performed on the counting result of the counting circuit that counts a predetermined timing signal, and each of the three rows arranged in the horizontal direction is processed. The pattern was decided.

Further, the display symbols after the power is turned on are automatically determined by a preset function of each circuit after each circuit of the display control device is initially reset.

With a display function other than the pachinko game machine described above,
For example, a display device of a game machine such as a slot machine is also displayed by a similar function.

[Problems to be Solved by the Invention] According to the above-mentioned conventional symbol determination means, since the display symbol determination of the symbol display device at the time of power-on does not have complete randomness, a plurality of symbols provided in parallel are not provided. Since all the amusement machines display the same symbol arrangement, there is a problem of giving the customer distrust, and there is also a fear that the big hit symbol is displayed from the beginning.

Further, since the symbols of the respective amusement machines at the start of the game are the same, the randomness of the symbol display function between the respective machines after the start of the game is also affected.

SUMMARY OF THE INVENTION An object of the present invention is to provide a display control device which solves the above-mentioned conventional problems and gives randomness to a symbol which is displayed first after the power is turned on, and in which a jackpot symbol is not displayed from the beginning. .

Wherein the delay signal generation circuit includes a resistor connected to a power supply circuit, a capacitor having one terminal connected to the resistor and the other terminal connected to a signal reference line, And a connection circuit for connecting a connection between the capacitor and the capacitor to a reset terminal of the microcomputer. Further, the address determination means sets a result obtained by performing a predetermined arithmetic processing so as to remove a predetermined numerical value from the count content value of the counting circuit as an address.

[Operation] According to the above configuration, after the counting circuit starts counting, the timing at which the computer is reset and the symbol display device is read is delayed, and the delay time can be made random. Randomness was able to be given to the display symbol of the symbol display device. Further, since the integrating circuit including the resistor and the capacitor is used for the delay circuit, the initial object is achieved at a low price. Also, since a predetermined calculation process is performed on the output value of the counting circuit, the address where the symbol data of the predetermined jackpot symbol is recorded is not set, so that the jackpot is not displayed simultaneously with turning on the power. Was.

FIG. 3 is a diagram showing details of one embodiment of the delay circuit 15 shown in FIG. 2. In FIG. 3, a connected to one terminal of the resistor 31 is an output from the power supply circuit 14 shown in FIG. The terminal on the opposite side of the resistor 31 is a terminal for inputting a predetermined DC power to be supplied, and one terminal of the capacitor 32 is connected to the Schmitt trigger 33.
Connected to the input terminal. The opposite terminal of the capacitor 32 is connected to a ground line as a signal reference line, and the output terminal of the Schmitt trigger 33 is connected to a microcomputer.
11 is connected to the reset signal input terminal 10.

 Next, the operation in the above configuration will be described.

When the power of the pachinko game machine is turned on, an AC power is input from the input circuit 13 to the power supply circuit 14, and a predetermined DC voltage rises and is output from each output circuit of the power supply circuit 14.

As described above, when the rising of the DC voltage supplied to each of the processing signal creation circuit 24 and the counting circuit 25 is completed,
The operation of each function is started according to a predetermined condition. That is, the counting circuit 25 starts counting the pulse train input from the processing signal creation circuit 24.

In addition, the rise of the DC voltage connected to the reset terminal 10 also proceeds, but due to the influence of the delay circuit 15, the reset of the computer 11 is delayed from the start of counting by the counting circuit 25 by the time delayed by the delay circuit.

That is, the DC voltage input to the input terminal a of the delay circuit 15 is increased exponentially by the Schmitt trigger 33 by the integration function of the resistor 31 and the capacitor 32. The setting voltage of Schmitt trigger 33 is a delay circuit
Since it is set close to the DC voltage value connected to 10, the integration function output voltage formed by the resistor 31 and the capacitor 32 approaches the saturation value, the voltage change rate decreases, and when the voltage reaches a predetermined set voltage. , Schmitt trigger 33 is triggered.

Since the Schmitt trigger 33 is triggered when the output voltage of the integration function approaches the saturation value and the rate of change of the voltage decreases, the time from turning on the power until the Schmitt trigger 33 is triggered is not constant. Without becoming unstable.

When the microcomputer 11 is reset by a reset signal input from the reset terminal 10, the microcomputer 11 starts up and operates according to a predetermined program condition.

The microcomputer 11 starts up, outputs an output signal when a predetermined condition is set in advance, inputs the count value of the counting circuit 25 to the arithmetic circuit 26, and with respect to this count value,
Different predetermined arithmetic processes are performed to determine the symbols provided in three columns, and the digital symbols are output to the address generation circuit 27 in digital code.

Since the contents of the above-described counting circuit 25 are affected by the above-mentioned unstable delay time, the numerical value obtained each time the power is turned on is indeterminate.

In the address creation circuit 27, the processing signal creation circuit 24
In order to display the symbols in synchronization with the predetermined synchronization signal created in the above, an address for sequentially reading the symbol data to be serially displayed on the symbol display device screen from the ROM 16 is created. To supply. The read symbol data is supplied to a symbol display device included in the operation function 18 in synchronization with the horizontal and vertical synchronization signals output from the processing signal creation circuit 24, and the symbols are displayed.

In the above description, the Schmitt trigger is used for the delay circuit. However, it is not necessary to use the Schmitt trigger depending on the condition of the reset input circuit of the microcomputer. Although the delay circuit uses an integrating circuit including a resistor and a capacitor, other delay circuits may be used.

Also, in order to not display a symbol that becomes a big hit when the power is turned on, for example, when the symbol has an odd value, the least significant digit of the digital code indicating the image signal output from the arithmetic circuit 26 is set to an even number. The process is performed.

This processing can be easily performed by performing processing such that the least significant digit always becomes, for example, high.

In the above description, the arithmetic circuit is configured by hardware, but may be performed by software processing by a microcomputer.

In the above description of the embodiment of the present invention, the description has been made of a pachinko game machine, but with other display functions, for example, in a game machine such as a slot machine,
The present invention can be implemented by matching the detailed operation specifications to the specifications of the game machine.

[Effects of the Invention] As described above, according to the present invention, a counting circuit starts counting as a means for generating randomness at the time of power-on in a display control device such as a pachinko machine or a slot machine having a display function. After that, the computer resets and delays the timing of reading the symbol display device, and since this delay time can be made random, the symbol displayed on the symbol display device after power-on can have randomness. Therefore, by changing the display pattern displayed on the display function of each amusement machine for each amusement machine at the time of the amusement hall opening, there is no fear of distrusting customers, and between the amusement machines after opening. The randomness of the stop symbols could be improved.

In addition, since the integrating circuit including the resistor and the capacitor is used for the delay circuit, the purpose of the processing is achieved at a low price. In addition, since the predetermined calculation processing is performed on the output value of the counting circuit, the address where the symbol data of the predetermined jackpot symbol is recorded is not set, and the jackpot is not displayed at the same time when the power is turned on. The excellent effect can be obtained.
