Further, swingable flippers 29 are provided on both sides of the ball drop opening 28 on the stage 26. Further, the stage is provided with a solenoid 33 (FIG. 5) below each flipper 29, and the swing of each flipper 29 is realized by the change of the magnetic field by the solenoid 33.

In addition, a transparent plate-shaped sensor 30 is attached to the entire lower part of the display cover 15 located immediately above the rear side of the stage 26. The sensor 30 changes the electric resistance by the contact of the game ball.

On the other hand, the screen of the LCD 14 displays "7, 7,
7 ”and“ 5, 2, 3 ”and other symbols are displayed as the symbol display portion L. It should be noted that each of the numeral portions, that is, the left portion L1, the middle portion L2, and the right portion L3 of the symbol is changed independently of or related to each other and displayed so as to be stopped. Further, cylindrical spacers 32, 32, ... Are projected forward around the symbol display portion L, and each spacer 32 is in contact with the rear surface of the display portion cover 15 of the front member 13.

Further, as shown in FIG. 5, the LCD 14 and the sensor 30 are the control device 35 installed in the pachinko machine 1.
Are electrically connected to each other via the I / O interface 43. Further, the solenoids 33, 34 for driving the members
Are similarly connected to the control device 35. Furthermore, various game ball detectors such as the game ball detector 36 in the warp zone 24 and the similar game ball detector 37 (FIG. 5) installed at the back of the special winning opening 9 are similarly controlled by the control device 35. It is connected to the. Furthermore, the operation hold indicator 23, the launching device, the illumination lamp, and the like are similarly connected to the control device 35.

The control device 35 includes a CPU 40 and a C
ROM 41 and RAM 42 connected to PU 40
, The I / O interface 43, and a loop counter 44 that takes a value that increases one after another so as to repeat within a certain range (for example, 0 to 255) based on the clock of the CPU 40.
And so on. The control device 35 is divided into several boards and arranged in the pachinko machine 1. Further, some substrates are incorporated in the members of the pachinko machine 1.

Then, the pachinko machine 1 operates as follows via the control device 35. When the firing handle 11 is rotated by the player, the game ball is fired toward the game area 6 with a strength according to the degree of rotation. The game balls that have reached the upper part of the game area 6 flow down while colliding with obstacle nails, windmills, etc., and win various prize holes, or are discharged through the out port 10 without winning.

When various prize holes are won, a predetermined number of prize balls are paid out to the supply tray 4 or the storage tray 5 by the payout device. Further, when the game ball P wins the ball entrance 21, it enters the distribution path 25 via the center of the introduction path 22,
Further, it reaches the one warp zone 24, falls, and passes through the game ball detector 36. The game ball detector 36 is a game ball P.
By passing through, an induced current is emitted as a detection signal. When the induction current flows in, the control device 35 causes the solenoid 3
Intermittent pulse currents are generated toward 3, 3 and the flippers 29, 29 are swung. Then, the game ball P reaches the ball outlet 27 immediately after passing through the game ball detector 36, and starts rolling on the front side of the stage 26 toward the ball drop opening 28.

By rolling, the game ball P approaches one of the flippers 29, and is flipped to the back depending on the timing of rocking. The game ball P that is vigorously played climbs the stage 26, contacts the sensor 30, and bounces off. If the momentum is insufficient, the stage 26 is returned to the front without climbing up.
The game ball P that has not been flipped or returned is either flipped by one of the flippers 29 or dropped from the ball drop port 28.

When the electric resistance of the sensor 30 changes due to the contact of the game ball P, the control device 35 receives a change in voltage as a fluctuation signal, and the control device 35, as shown in FIG.
Based on the presence or absence of a voltage change, the contact of the game ball with the sensor 30 is determined (S12), and only when there is contact, the RAM4
The value M of operation suspension stored in 2 is increased by 1 within the range of a predetermined upper limit (here, 4 times) (S13) 1 (S14). The initial value of operation suspension is 0 (S11). Further, the value M of operation suspension is displayed on the operation suspension display 23 by the control device 35.

Further, the control device 35 has not caused a special game state (S21), has stopped the symbol on the symbol display portion L of the LCD 14 (S22), and the value M of the operation suspension is If it is not 0 (S23), the value M of operation suspension is
Is decremented by 1 (S24), and the symbol on the symbol display portion L is changed (S25). After starting the fluctuation, the control device 35 refers to the value C of the loop counter 45 (S26).

When the referred value C is a predetermined value (for example, 7), the control device 35 changes the symbol in a state including a special mode (so-called reach operation) (S28).
a) After a lapse of a predetermined time, it is stopped with a predetermined symbol (a winning symbol, for example, "7,7,7""3,3,3" ...) (S29a). And after stopping, as a special game state,
An intermittent pulse current is emitted toward the solenoid 34, and the special winning opening 9 is opened intermittently (for example, about 20 seconds each time) (S30). The control device 35 opens the special winning opening 9,
The special game state is maintained for a predetermined number of times (for example, 16 times), and after that, the pulse current to the solenoid 34 is stopped to close the special winning opening 9, and the winning symbol is stopped. In addition, when the induced current of the game ball detector 37 behind the special winning opening 9 is received, that is, due to the winning of the big winning opening 9 of the game ball, an extremely large number of prize balls are paid to the supply tray 4 or the storage tray 5 by the payout device. The RAM 42 stores the cumulative number of winning prizes for each opening. If the cumulative number of winnings exceeds a predetermined upper limit (for example, 10), the pulse portion is forcibly cut even within a certain period of time, and the special winning opening 9
Close. Further, during the special game state, an animation is displayed on the background of the symbol display portion L (a portion other than the symbol portions L1 to L3), and the illumination lamp is turned on to generate a predetermined fanfare from the speaker.

On the other hand, when the referred value C is other than the predetermined value, the control device 35 changes the symbol (S28
b), after a lapse of a predetermined time shorter than the case including the reach operation, it is stopped with a symbol other than the prescribed symbol (deleting symbol) (S29b).

Note that the ROM 41 of the control device 35 holds certain information such as a part of the operation program, a pattern of a predetermined symbol, and a value of a loop counter that causes a special game state.

In the pachinko machine 1 as described above, since the operation suspension that causes the fluctuation of the symbol occurs due to the contact of the game ball P with the sensor 30, the game operation leading to the occurrence of the special game state is the prize winning device. Can get a different, completely new taste. Moreover, since the sensor 30 is attached to the front side of the symbol display portion L where a predetermined symbol is stopped, the player looks at the symbol display device 7 in order to confirm the occurrence of the special game state, You can also see the movement of the game ball that leads to suspension of operation, and you can play with an extremely high level of interest. By installing the stage 26, warp zone 24, and flipper 29, the game ball P
Can be smoothly guided to the front side of the symbol display portion L of the symbol display device 7. Further, by installing the flippers 29, 29, it is possible to impart a variety of movements to the game ball P, which can further arouse the player's interest.

Further, since the operation suspension is generated by the game ball P flowing down in the symbol display device 7, the symbol display device 7
It is not necessary to install a winning device (symbol starting port) that causes operation suspension in other game areas 6, and even if the symbol display device 7 is large, it is possible to prevent the player's interest from being lowered, and the game area 6 Can be effectively utilized. Since the sensor 30 is transparent and is attached to the lower edge of the display unit cover 15, the visibility of the symbol display unit L is good, and the attachment of the display unit cover 15 allows the LCD 14 to play the game ball P. Does not cause any pain.

[Second Embodiment] FIG. 8 shows a pachinko machine 2 according to the second embodiment. Since the pachinko machine 2 has the same configuration as the pachinko machine 1 on the game area 45 except for the symbol starting port 46 and the symbol display device 47, the description thereof will be partially omitted and the corresponding members will be denoted by the same reference numerals. Indicate.

In the game area 45 of the pachinko machine 2, a symbol display device 47 having the same structure as the symbol display device 7 is provided in the center except that the position of the sensor is different.
Below the ball dropping port 28 of the symbol display device 47, a symbol starting port 46 in which a game ball wins is mounted. Design starting port 4
6 is arranged close to the ball drop port 28 so that the game ball P that has passed through the ball drop port 28 has a higher probability of winning than a game ball that does not pass. Further, a game ball detector (not shown) similar to the game ball detector 36 is installed behind the symbol starting port 46.

The symbol display device 47 includes a front member 48 and an LCD.
As shown in FIGS. 9 and 10, the front member 48 is provided with a sensor 50 similar to the sensor 30 in the back of the stage 26 and on the front side of the display unit cover 15. The sensor 50 detects the contact of the game ball P rolling around the upper edge of the stage 26.

The pachinko machine 2 is controlled by the controller 35.
It is controlled similarly to the pachinko machine 1. In addition, the control device 35
When the detection signal of the game ball detector behind the symbol starting opening 46 is received, the value M of operation suspension is within the predetermined upper limit, and the sensor 50
Increases by 1 independently of.

In the pachinko machine 2, because the operation suspension leading to the occurrence of the special game state occurs due to the contact of the game ball with the sensor 50 and the winning of the symbol starting port 46 below the ball drop port 28. Even if the game ball comes out of the symbol display device 47 without contacting the sensor 50, there is an opportunity of operation suspension, and it is possible to diversify the game contents according to the flow of the game ball, which makes the player entertaining. Can be evoked. Also,
Since the sensor 50 is attached to the stage, the player can confirm the occurrence of operation suspension due to contact while visually recognizing the pattern.

[Third Embodiment] The pachinko machine according to the third embodiment is the same as the pachinko machine 2 except for the installation position and type of the sensor and the control method relating to the sensor.
Only the symbol display device 3 and the flowchart are shown in FIGS. 11 to 13, a part of the description is omitted, and corresponding members are denoted by the same reference numerals.

On the lower side of the display cover 15 of the symbol display device 3, there are added sensors 51 which are divided into three regions 51a to 51c which are horizontally arranged and have the same width so as to correspond to the respective portions L1 to L3 of the symbol. It is set up. Each of the regions 51a to 51c changes resistance of different size (attaching position information) by contact of a game ball, and changes voltage of different size to each connection circuit of the control device 35 (display change signal). ) Bring.

In the pachinko machine according to the third embodiment, the controller 35 controls the pachinko machine until the game ball P exits from the ball outlet 21 in the symbol display device 3 and before it falls from the ball drop port 28. It is controlled similarly to 1.

When the game ball P exits from the ball outlet 21, it is launched by the flipper 29 or dropped from the ball drop port 28 as it is. Game ball P launched
Is returned by contact with the sensor 51 or gravity, and is launched again. Or it falls.

When the game ball P contacts the sensor 51, the control device 35 judges the contacted regions 51a to 51c according to the magnitude of the voltage change as shown in FIG. 12 (S41).
~ S43), if the symbol portion corresponding to the contact area is changed (S44a to S44c), the type of the symbol portion to be animated is selected (S45a to S45c), and a predetermined animation in the symbol portion corresponding to the contact area is performed. (Here, as shown in FIG. 11B, the stop symbol portion or the selected symbol portion “7” is gradually reduced in size and then returned to the original size) (S46a)
~ S46c). That is, the control device 35 changes the display mode of the corresponding symbol based on the display change signal having the position information. If the symbol has been changed immediately before, stop processing is not performed until the end of the animation of the symbol. Further, the value M of the operation suspension is increased by 1 by winning the symbol starting opening 46 as a predetermined condition, but is not increased by the contact of the game ball with the sensor 51.

In the pachinko machine according to the third embodiment, the control device 35 recognizes the contact of the game ball with the sensor 51 via the display change signal, and when it is recognized, the symbol display on the symbol display section L is displayed. Since the mode is changed, the display mode of the symbol display portion L can be varied and can be closely related to the flow down of the game ball. Therefore, even if the symbol display device 3 is large, the player can enjoy the display of the symbol display portion L while watching the downflow of the game ball interestingly in the pachinko machine according to the third embodiment.

Further, the sensor 51 has areas 51a to 51a.
It is divided into c and sends a display change signal with the position information of the area, so the symbols L1 to L according to the position information.
By displaying only 3 as an animation, it is possible to perform the effect that the game ball has pressed the design,
It is possible to raise the interest of the player to a high level by providing a display mode of the fresh symbol display portion L.

The present invention is not limited to the above embodiment, but can be modified in various ways, as will be partially shown below. The sensor 30 does not need to adopt a sensor that changes the electric resistance by the contact of the game ball, and can change the electrostatic capacitance or the electromagnetic induction current or a combination thereof. Further, the sensor does not need to send a physical quantity change directly caused by the contact of the game ball as a signal, but may send a physical quantity change processed by further conversion. That is, as long as the control device can recognize the various signals, the mode such as the direction of change in voltage and current, the presence / absence / direction of propagation, or the priority of processing after recognition is not limited. The same applies to the game ball detector.

Further, the control device 35 does not have to be divided into several substrates, but may be composed of a larger number or a single substrate. The loop counter may be clock-based or decremented. Further, the symbol display device is not limited to the LCD and may be a CRT or the like. In addition, the materials and dimensions of various members are not limited to those in the above embodiment, the sensor may be opaque, and the game ball detector need not be wound with a solenoid.
