A shielding piece 30 is arranged on the starting opening 13 so as to move forward and backward with respect to the game board 3, and the starting opening 13 is covered at its extended position. This shield piece 30
Is converted into an open position (retracted position) and a closed position (extended position) by a drive device 31 including a solenoid shown in FIG.

The opening / closing control of the drive unit 31 is executed by the central control unit MPU shown in FIG.

Below the starting opening 13, a variable winning device 22 having a wide special winning opening is arranged. This variable winning device 22 has a publicly-known configuration in which a lid 24 is opened in the front-rear direction by a solenoid and a guiding action of the lid 24 guides a game ball to a special winning opening 23. A central portion of the special winning opening 23 is provided. As a specific area, when the game ball enters the specific area, the ball is detected by the V winning switch and the continuous opening operation is caused.

In the microcomputer having such a configuration, the central control unit MPU gives control signals to various devices in response to the output of each control signal according to the program data stored in the storage device ROM. On the other hand, signals from the winning switch, the count switch, and the V winning switch of the starting opening 13 are given to the central control unit MPU. Further, the signal output from the central control unit MPU causes the driver to drive the symbol display device 6, the drive device 31 of the shield piece 30, the solenoid of the variable winning device 22, the stored number display LED 11, the lamp and the like.

Next, the control mode of the symbol display device 6 will be described.

Here, each of the symbol display devices A, B and C sequentially circulates from "0" to "9" and then from "A" to "F", and displays this as one cycle.

Then, the symbol display device C is stopped and the symbol display devices A, B and C are, for example, "1, 1, 1", "2, 2,".
2 ”,“ 3, 3, 3 ”,“ A, A, A ”, etc., when the symbols composed of numbers or alphabets are the same,
It becomes a "big hit", the notification device emits a fanfare, and the solenoid of the winning device 22 is driven, so that the lid 2
4 tilts forward and the special winning opening 23 is opened, and about 10 game balls are won or opened until a predetermined time elapses. The special winning opening 23 is continuously driven when passing through the specific area, and the special winning opening 23 is released again after the opening operation is completed. The maximum number of continuous operations is 16 including the first opening.

In this symbol display device 6, a ball is inserted into the starting port 13 and the detection switch S1 is turned on to drive or win the prize. Then, the inflow of the hitting balls into the starting opening 13 is controlled by the shielding piece 30.

This shield piece 30 relates to the main part of the present invention, and the drive control mode thereof will be described.

The shield piece 30 is continuously advanced and retracted by the continuous switching control of the drive device 31, and the operation of converting the starting opening 13 into the open state and the closed state is generated. For example, assuming that the shield piece 30 causes a continuous opening / closing operation in which the predetermined opening time T ₁ and the predetermined closing time T ₂ are alternately repeated, T ₁
= T ₂ = 2 seconds. As a result, only when the ball is in the retracted position, the ball can be introduced into the starting port 13, the inflow timing must be appropriate, and the inflow mode is changed.

Although a configuration in which the shield piece 30 is simply and continuously opened and closed is proposed, the shield piece 30 can be associated with various condition devices to cause various operations as described below. An example of the operation mode will be described below.

In a normal state, the shield piece 30 is continuously moved forward and backward, and the shield piece 30 is kept open depending on the contents of the big hit operation of the symbol display device 6. For example,
When the display symbol of each of the symbol display devices A, B, C of the symbol display device 6 becomes "777", the shielding piece 30 is maintained in the open state until the next big hit. Thereby, the drive rate of the symbol display device 6 is improved by the display contents of the symbol display devices A, B, C, and a new gain is generated.

Further, in a structure in which a normal symbol display device is arranged on the symbol display device 6 and the ball is passed through a starting gate provided on the game board 3, the device is activated. Alternatively, the shielding pattern 30 may be maintained in the open state for a predetermined time when the normal symbol display device is specific. This predetermined time may be maintained, for example, for 10 seconds, or the normal symbol display device may be continuously opened until a predetermined symbol (corresponding to Bubba) is displayed.

When the predetermined condition is satisfied, the opening time T
₁ may be set longer than the closing time T ₂ .
For example, as described above, in the case where the ordinary symbol display device is provided, the opening time T ₁ may be set longer than the closing time T ₂ when the ordinary symbol display device is specific. For example, in a steady state, if T ₁ = T ₂ = 2 seconds, and if a predetermined condition is satisfied, T ₁ = 5 seconds and T ₂ = 2 seconds can be considered. This advantageous opening / closing operation time may be maintained, for example, for 10 seconds, or the normal symbol display device may be continuously opened until a predetermined symbol (corresponding to Bubba) is displayed.

In a normal state, the shielding piece 30 is continuously moved forward and backward (opening and closing operation), and the shielding piece 30 is maintained in a closed state according to the display content of the symbol display device 6.
For example, "X" is mixed in each display symbol of each symbol indicator A, B, C of the symbol indicator 6, and symbol indicator A, B, C
When "X" appears in any of the above, the shielding piece 30 is maintained in the closed state for a predetermined time. "X" corresponds to so-called Bubba, which causes a change in the pachinko game.

In each of the above constructions, the conventional starting port 13
The rate of inflow into the starting port 13 is reduced as compared with the configuration in which the opening is left open. However, in order to secure the same inflow rate as the conventional one and generate the gain by the above-mentioned inflow timing profit or the satisfaction of the predetermined condition, a plurality of the starting ports 13 are provided, and one of them is opened. Alternatively, the shield piece 30 may be arranged. Further, even if the inflow rate into the starting opening 13 decreases, it is possible to secure a harmonious payout as a whole by means such as improving the probability of a big hit of the symbol display device 6.

Further, the opening time T ₁ and the closing time T ₂
If the control is possible, there is an advantage that the operating rate of the symbol display device 6 can be adjusted.

FIG. 5 shows another embodiment of the shielding piece 30 in which a holding groove 32 consisting of a V groove on which one ball is placed is formed on the upper surface thereof. In this configuration, the shield piece 30
When the ball x is in the closed position, the balls can be mounted on the holding groove 32, and when the ball x is supported on the holding groove 32 in a well-balanced manner, the shielding piece 30 retracts in the mounting state. Then, the balls on the holding groove 32 can fall into the starting opening 13.

In addition to the structure of the shield piece 30 that moves forward and backward orthogonally to the play board 3, a structure in which the shield piece 30 is rotated up and down to be converted into a position where the starting port 13 is opened and a position where the starting port 13 is closed is also applied. obtain.
