In view of the above-mentioned problems, the invention according to claim 1 is made, and a starting port and a variable display means capable of changing a display state of a display portion for displaying a design, Based on the display state of the variable display means, a ball game machine configured to include a variable winning means that can be changed to a first state that is advantageous for the player and a second state that is disadvantageous The variable display means makes the design of the display unit invisible by blocking the visibility of at least part of the design of the display unit with a mask based on the fact that a hit ball has entered the starting opening. Blocking means, and a pattern appearance means for gradually making visible a pattern made invisible due to the structure scratched from the pattern masked by the visual recognition preventing means and making it visible, the disappearance of the mask, the It is an pinball game machine according to claim be associated display a different video and symbol and the mask of the radical 113. The "visual recognition prevention means" here constitutes a display mode in which the pattern cannot be visually recognized due to concealment or occlusion (hereinafter referred to as a mask), blurring, and the like. The "pattern appearance means" can be visually recognized by various configurations such as scratching the masked pattern (meaning it is torn as if it was scratched by a nail) or gradually sharpening the blur. It is intended to form a display mode in which an impossible pattern is gradually made visible and visible. This enables a novel display operation that has never existed before, and it is impossible to predict which symbol will be hit or miss until the symbol appears, which results in a thrilling game. is there.

According to a second aspect of the present invention, the symbol appearance means responds to a plurality of appearance order data corresponding to a plurality of appearance orders and random number data selected due to entry or passage of a game ball. An appearance order data selecting means for selecting a predetermined appearance order data from the plurality of appearance order data, and a ball game machine characterized in that.

The configurations of the b, the touch switch 13c, the upper tray clogging switch 13d, etc. are well known and will not be described.

Next, the liquid crystal display screen 4 as a special symbol display device will be described in detail. As shown in FIG. 2, the liquid crystal display screen 4 is arranged in 3 rows and 3 columns, and masks of special symbols and first to ninth variable display parts w1 to w9 for performing appearance display.
Is equipped with. When it is determined that the three-digit special symbols forming the hit lines L1 to L8 are equal in numerical value, the special winning opening 36 described later is changed to a state advantageous to the player (special game state). It is configured. That is, the first to ninth variable display parts w1 to w9 are respectively "1",
Consists of a symbol array consisting of five types of numbers consisting of "3", "5", "7", and "9", of which the winning symbols are three digits for any one of the aforementioned winning lines L1 to L8. It is established when the values are the same (doublet), and other than that, it is a deviating symbol. The special symbol consisting of a combination of integer values displayed in a matrix of 3 rows and 3 columns is displayed on the liquid crystal display screen 4
At first it is masked. Examples of this mask include various patterns such as a hatching pattern, solid coating, point depiction (bitmap), pattern, gradation, and the like, and can be appropriately selected from these.

Next, as shown in FIGS. 3 (a) to 3 (c), the special symbols of the first to ninth variable display parts w1 to w9 are initially masked, but one selected randomly. The mask is gradually scratched and wiped (erased) to appear in each display unit in a predetermined order, and each special symbol is finally completely displayed. The scratch here means that the masked part is torn as if scratched by the nail as described above, and the scratch gradually progresses so that the special pattern gradually appears. The display screen is configured in. The scratch speed is set to an appropriate speed suitable for the content of the game, but it is also possible to change the scratch speed to proceed. In addition, it is possible to adopt various modes such as a case where scratches are used to uniformly reduce the mask, or a case where scratches are made to change while increasing or decreasing the mask area. is there. Although the scratch is formed by a sharp straight line, it can be changed to a curved line, a wavy line, or the like.

The appearance order of the special symbols is to follow any one of the seven appearance order data randomly selected as shown in the appearance order table (stored in the ROM 11) shown in FIG. For example, if the count value is 5 as shown, the fifth variable display section w5, the first variable display section w1,
The respective masks are scratched in the order of the second variable display portion w2 and the fourth variable display portion w4, and the corresponding special symbol appears, as shown in FIG.
The display state shown in FIG. Then the seventh variable display section w
Masks of 7, the sixth variable display portion w6, the eighth variable display portion w8, and the third variable display portion w3 are scratched and a corresponding special symbol appears, and the reach display state shown in FIG. 3B is obtained. Next, as shown in FIG. 3C, the mask of the ninth variable display portion w9 is gradually scratched and gradually appears. These scratch speeds are set equal. Also, in the non-reach display, the same display order configuration is used. If the count value is 6, the first to ninth variable display parts w1 to w9 are all scratched at once.

Whether or not the special symbol is determined is determined randomly by a special symbol determination random number. Special symbol success / failure determination counter 15a as a random number generator
After the power is turned on, the initial value is set to "0", and 300 kinds of numerical values from 0 to 299 are repeatedly incremented in ascending order for each reset interrupt (2 ms). Further, as will be described later, if a big hit is made with a specific symbol among the big hit symbols, it is set to change the probability from the low probability mode to the high probability mode when the first big hit operation ends, and thereafter, at least 2 The high probability is secured for the times, and the low probability mode is returned to. On the other hand, the big hit symbol is set so that probability fluctuation does not occur except for the specific symbol.

The hit line is randomly decided by a hit line decision random number. After the power is turned on, the hit line determination counter 15b as a random number generator has an initial value of "0", and eight kinds of numerical values 0 to 7 are set in ascending order for each reset interrupt (between 0.01 ms and 2 ms). It is to repeatedly increment. Any of the hit lines L1 to L8 shown in FIG. 2 is selected in correspondence with the hit line determination random numbers 0 to 7.

The determination of the jackpot symbol of the special symbol is designed to be randomly determined by a random symbol determination random number. The winning symbol determination counter 15c as a random number generator,
After the power is turned on, the initial value is set to “0”, and five kinds of numerical values 0 to 4 are incremented in ascending order and repeatedly for each reset interrupt (between 0.01 ms and 2 ms). Corresponding to the hit symbol determination random number value 0 ~ 4, the big hit symbol array,
Any one of “111”, “333”, “555”, “777”, and “999” is selected and displayed on the selected hit line, and the hit symbols are not displayed on the remaining lines. .

The determination of the special symbol scratch order is such that it is randomly determined by the special symbol scratch order determination random number. The special pattern scratch order determination counter 15d as a random number generator, the initial value is set to "0" after the power is turned on, and seven kinds of numerical values 0 to 6 are repeated in ascending order for each reset interrupt (for 2 ms). It is to increment. As shown in FIG. 4, corresponding to the special symbol scratch order determination random number values 0 to 6, one of the seven appearance order data is randomly selected.

The determination of the deviation symbol is such that it is randomly determined by the deviation symbol determination random number. The nine out-of-range symbol determination counters 15e to 15m as random number generators have an initial value of "0" after power-on, and four kinds of numerical values 0 to 4 are reset interrupts (for 2 ms), The deviating symbol determination counters 15e to 15m are sequentially and sequentially incremented. In addition, even if it is not a hit, if the decided special symbol accidentally becomes a hit symbol, either 1
The numerical value indicated by the two special symbols is shifted by one, and the correction is forcibly corrected.

The CPU 10 randomly reads the count values of the counters 15a to 15m as the random number generator and stores them in the RAM 12. Further, predetermined data is stored in a predetermined area of the ROM 11 corresponding to each of these count values.

The ball game machine 17 shown in FIG. 5 having the electronic control unit 1 will be described. The ball game machine 17 has an outer frame 17a.

On the liquid crystal display screen 4, a special symbol is masked based on the fact that the hit ball has been won in the first-type starting opening 32 or 33, and after a certain time (for example, 5.9 seconds) has passed, the mask is sequentially scratched, and each special I try to make the design appear.

Then, when the combination of the identification information at the time of appearance of the special symbol becomes a predetermined big hit symbol (for example, the specific display result of the doublet pattern of 7), the special game state is set and the speaker.
A big hit sound is generated from 23, and the special winning opening 36 is 2
It is set to open for 8.7 seconds (or until 10 prize balls occur, even if it is within 28.7 seconds until that time), and the hit ball that falls in the game area 24 is specified during the opening. It is intended to be received in area 37. When the received hit ball turns on a specific area passage detector (not shown), the continuation right is established and the above-mentioned open state can be repeated 16 times in succession. On the left and right of the liquid crystal display screen 4 are normal design gates 30

Below the special winning opening 36, an ordinary symbol display section 38 and an ordinary symbol variation storage LED 39 are provided. The normal symbol display unit 38 starts variable display in response to the hit ball passing through the normal symbol actuation gates 30a and 30b, and stops after 27.998 seconds when the probability is low and after 5.001 seconds when the probability is high, When the display result at the time of appearance is "7", it is judged as a win.
In that case, the first type starting port 33, which is an ordinary electric accessory, should be open-driven until 0.590 seconds when the probability is low, 1.704 seconds when the probability is high, or until three winning balls are generated. I have to. In addition, the winning ball that has won the first type starting opening 32 or 33 is guided to the back surface of the game board 18 and can be detected by the starting winning ball detector 34.

The normal symbol variation storage LED 39 is for displaying the number of hit balls that have passed through the normal symbol actuating gates 30a, 30b, and the number of reserved rights for variably displaying the normal symbol display portion 38, and can store up to four. I am trying.

On the left and right of the big prize hole 36, a lower prize hole 40a,
40b is provided, and lamp windmills 41a, 41b are provided on the left and right of the upper part of the game area 24. Other, game area 24

The configuration of the back surface of the game board 18 of FIG. 5 is well known, and although illustration and details are omitted, well-known members such as various detection sensors, accessory, lead wires connected to lamps, etc. Is provided, and a control panel (not shown) storing the electronic control unit 1 is also provided.
32, 33, the winning balls that have won the lower winning openings 40a, 40b are collected in the winning path, and the number of prize balls is relatively small (7)
The balls that have won the other winning holes and the winning areas are collected on another winning path, and a relatively large number of prize balls (15) are paid out. There is.

The special operation of the present embodiment will be described with reference to the flowchart shown in FIG. When the ball game machine 17 is connected to a power source and power is supplied to each circuit from a power source (not shown), the CPU 10 performs a series of initial settings such as flags and counters and executes a main routine (not shown). At the same time, this special determination processing routine is activated by an interrupt. First, when the process starts,
The player waits for a ball entry signal from the starting winning ball detector 34 (S100), and if it is determined that there is no ball entry signal, the procedure returns to the return. On the other hand, when a hit ball is won in the first type starting opening 32 or 33, the starting winning ball detector 34 generates a ball entering signal, so that an affirmative determination is made and masking of the first to ninth variable display parts w1 to w9 is performed. (S101). At this time, the special symbol hit / miss determination counter 15a,
Winning line determination counter 15b, winning symbol determination counter 15
c, the special symbol scratch order determination counter 15d, and any one of the count values of the out-of-design symbol determination counters 15e to 15m are respectively taken out and stored in the RAM 12. In addition, the count value of the special symbol hit / miss determination counter 15a at the time of winning, and the count value of the deviation symbol determination counters 15e to 15m at the time of deviation are alternatively stored.

Then, after a small amount of time has elapsed from the start of the mask of the special symbol on the liquid crystal display screen 4, the count value of the special symbol winning / deciding determination counter 15a stored in the RAM 12 is taken out, and whether the value corresponds to the jackpot value. If it is applicable, it is determined to be a big hit, and if it is not applicable, it is determined to be out (S102).

At this time, the probability variation process is performed in another routine, and the transition between the low probability time and the high probability time is processed, and the big hit symbol is two of these (for example, 3, If it corresponds to the specific pattern of 7), after the first big hit process is completed, the probability is improved by shifting from the low probability time to the high probability time, so that the high probability is guaranteed in the subsequent two big hits. It has become. At such a high probability, if a big hit is newly made with the above-mentioned specific symbol, and from then on, the high probability is guaranteed in the following two big hits, and when such a high probability ends, it returns to the low probability. It is set. On the other hand, if the big hit symbol is a big hit symbol other than the specific symbol, even if the first big hit process is finished, it remains at the low probability and the probability fluctuation does not occur.

Next, when a positive determination is made in S102, RA
The count value of the hit line determination counter 15b stored in M12 is read from the RAM 12, and L1 to L8 shown in FIG.
One of the hit lines is selected (S103).

Next, in the case of a big hit, the count value of the hit symbol determination counter 15c stored in the RAM 12 is stored in the RAM 12
Is read out and one corresponding big hit symbol is determined according to this numerical value (S104).

On the other hand, if the hit random number is not obtained, a negative determination is made in S102, the count values of the deviation symbol determination counters 15e to 15m are read from the RAM 12, and 1 corresponding to this count value is read.
Two off-designs are determined (S105).

Next, the special symbol scratch order determination counter
The count value of 15d is read from the RAM 12, and one of the seven appearance order data corresponding to this as shown in FIG. 4 is randomly selected, and the order of special symbol scratches is determined (S106). Next, in accordance with this order, the scratch operation is instructed to each display section (S107), and each special symbol is displayed (S108).

It is determined whether or not the special symbol displayed on the liquid crystal display screen 4 is a winning symbol (S109), and if a negative determination is made, the process returns to the return, and if an affirmative determination is made, the special game described above is entered (S110). That is, output of a big hit sound from the speaker 23, turning on of the various LEDs 29a, 29b, etc. are instructed, the special winning opening 36 is opened for a predetermined time, and a hit ball falling in the game area 24 is received in the specific area 37 during that time. Process. Then, it is determined whether or not the jackpot processing is completed (S11
1) If a negative decision is made, the process returns to step S110 to repeat the processing. On the other hand, if the affirmative judgment is made, the process returns to the return.

By repeating these processes, the liquid crystal display screen 4 enables an unprecedented novel display operation, and until the special symbols appear on the first to ninth variable display parts w1 to w9, Since it is impossible to predict which of the hits will be missed, a thrilling game is provided. Further, as shown in FIG. 4, since the appearance order data is randomly selected, there is an effect that the appearance pattern cannot be predicted. Further, when the reach display is made on the eight hit lines, it is possible to give an expectation that the hit pattern will be obtained regardless of whether the hit is missed or not.

Next, the scratch operation at the time of reach performed by the electronic control unit (having the same configuration as that of FIG. 1) of the ball game machine according to another embodiment different from the above will be described. What is different from the above is that first, the scratch operation at the time of the reach is slow to increase the expectation for the big hit, and secondly, as shown in FIGS. , If there is a similar portion between the reach special symbols and other masked special symbols constituting one line, if there is a similar portion, that portion It is to scratch from.
As a result, the expectation for thrills and hits during reach is increased. As a special pattern with similar parts,
There is one illustrated in (c).

This is as indicated by the dotted circle,
These are the lower part of "1" and "7", the lower right part of "3" and "5", and the upper part of "3" and "9". By scratching these similar special symbols, the player is made to feel the illusion as if they were a winning symbol, and the expectation for winning is increased. An example in which they are scratched is shown in FIGS. 7 (a) and 7 (b). If the reach design and the masked special design are dissimilar, it can be immediately recognized by the player that they are out, and if the hit design is scratching, no matter where the scratch is made, the expectation is increased. However, here, you can increase the expectation by scratching from the same place as in a similar case.
The description of the components common to the above-described embodiment will be omitted.

In order to implement the above-mentioned operation, in addition to the processing shown in FIG. 6, the flowchart shown in FIG. 8 executed by interruption is added. That is, first, it is determined whether or not reach (S200), and if affirmative determination is made, it is determined whether or not the reach symbol and other masked special symbols constituting one line are the same or similar (S201), and normal. As described above, the image data is stored in the image data RAM and is changed to the image data having the characteristic scratching speed which is slow and the similar portion is scratched (S202), which is read out and the reach operation is executed. . It is determined whether or not the reach has been completed (S203), and when the determination is affirmative, the image data described above is changed to the image data for displaying the normal scratch operation stored in the RAM 12 (S20).
4) Return to return. In addition, when a negative determination is made in S200, S201, and S203, no processing is performed and the process is returned. If the reach symbol is not similar to the other masked special symbol, the image is displayed as a normal scratch operation.

It should be noted that instead of the scratch described above, FIG.
As shown in FIG. 7, it is possible to display the image as if the special pattern appears gradually and gradually becomes clear from a state where the pattern is blurred and invisible.

Although the present embodiment has been described above, it goes without saying that the configuration of the present invention can be appropriately modified without departing from the technical idea of the present invention, and such modifications are also within the technical scope of the present invention. Belong to. For example, the masks are not limited to the same type, and different types of masks may be used, such as a mixture of solid painting and hatching. Also, scratching starts from the corner of the display,
It is also possible to start from another location, such as the middle. When scratching a mask, it is possible to display videos of human hands, animal hands, drills, excavators, etc. where the mask is being cut, so that the masks can be reduced accordingly. is there. The special design may be a design instead of a number. Instead of the 3-row 3-column display section provided on the liquid crystal display screen 4, a 3-digit display section may be used. The color of the liquid crystal display screen 4 can be changed for each display unit. LCD display screen
Instead of 4, it is also possible to display with another display configuration such as a rotating drum. The present invention can also be applied to other types of ball game machines such as so-called right-of-use models, arrange ball game machines, and time saving machines.
