Description

[Detailed Description of the Invention] The present invention relates to a pachinko machine, which has a structure in which a series of operations in which a predetermined amount of prize balls are ejected as the balls are redeemed are carried out via electrical signals, from the detection of safe balls to the prize winnings. To provide a pachinko machine which makes the operation up to the discharge of balls sharp and reliable, and allows a fair pachinko game to be played at all times by calculating and matching the number of safe balls and the number of times prize balls are discharged.

Pachinko machines that have been commonly used in the past are
The ejection of the prize balls by the safe balls is a mechanical interlocking method that uses the weight of one safe ball to operate the prize ball ejector via a link mechanism etc. Because the balls are continuously struck. A complicated mechanism (so-called renchan mechanism) is required to match the number of safe balls and the number of prize balls to be ejected when a user receives a call, and malfunctions of this mechanism frequently cause malfunctions such as ball jams. In addition to the mistakes that occur, there are also many failures in the mechanical parts, and this has many drawbacks in implementation, such as the unreasonableness that often occurs when the number of safe balls and the number of prize balls that are ejected do not match.

The present invention has been made with the aim of eliminating such drawbacks, and one embodiment thereof will be described in detail below with reference to the drawings.

In the drawings, (1) shows a safe ball collection passageway with multiple safe ball receiving holes provided on the playing board surface of a pachinko machine, (2) shows a safe ball collection passageway (1) has a safe ball collection passageway with multiple safe ball receiving slots installed In the detection passage, a hollow is formed, and the bent part has a safe ball holder part (8a) on which seven safe balls (A) are placed and a safe ball holder part (8a) on which seven safe balls (A) are placed. The weight of the safe ball (A) resting on 8a) causes the tip to descend and release the safe ball (A).
) When sending out the next safe ball (8), move the control rod (3) with the stopper regulating protrusion (3b) to the weight (3) at the rear end.
8c), the center of gravity is shifted to the rear and the support shaft (4) & Koyoshi swingable pivot are supported, creating a safe ball gathering passage (1)
[The control rod (3) ensures that nine safe balls arranged in 97 rows and rolling in the upper passage (2a) of the safe ball detection passage (2) are sent out seven by seven to the lower passage (2b). I'm doing it. (S) is a safe ball detection sensor installed at the refraction part of the safe ball detection path (2), and it does not block the light projected between the opposing projectors and receivers (5) and (6). It uses a switch with a structure that allows it to explode.
When the projecting plate (7) provided at the tip of the control rod (3) sends out the safe ball, the safe ball receiver (8a) lowers with the weight of the safe ball (~) and emits the safe ball (5). , (a) to block light between them, so that the prize ball ejector (B), which will be described later, is operated via an electronic circuit (C). Ball detection m7 sir (S) &
, : may be implemented freely even if a sensor other than the above embodiment is used. (So) is an auxiliary detection switch installed near the exit of the lower passage (2b) of the safe ball detection passage (2),
If the control rod (3) only sends safe balls and sends two or more balls at the same time, and the sensor (S) detects only seven balls, the auxiliary detection switch (Sl) is activated. This is to ensure the accuracy of counting. (B) is a prize ball ejector that dispenses a predetermined amount of prize balls (usually 7
Each time a ball is received, the swinging machine (8), which can store 5 balls, is made to swing back and forth to eject the prize ball and replenish the next prize ball. Drive device (D
), a solenoid (
An operating rod (11) is connected to the plunger (9) with one end pivoted from the support shaft aQ & so that it can swing freely, and the other end of the operating rod (11) is connected to the negative side of the rocker (8). The solenoid's plunger (
By moving up and down), the other end of the operating rod α1) is moved up and down, and the swinging machine (8) is tilted to the left and right via the engaging protrusion (b)), and the prize balls in the swinging machine (8) are Ejection and replenishment of the next prize ball into the shaking machine (8) are performed. In addition, although a downpipe type prize ball ejector (B) is used in the example, it is also possible to use a prize ball ejector with 7 legs/masks.
.

In addition, although a slide/id (b) is used as the drive device (D), a motor may be used instead of a solenoid to move the other end of the operating rod up and down by the rotational movement of the motor. αB) is a weight for returning the swinging gutter, and when discharging prize balls, the swinging machine (8) is lifted and tilted through the engaging protrusion at the other end of the operating rod (1υ), but the lifting force is released. As a result, the oscillating machine (8) automatically returns to the prize ball replenishing position with the weight indicated by the weight a.

(S2) is a switch that detects the number of times the prize balls are ejected by the prize ball ejector (B) and lights up an indicator lamp to indicate that when the prize balls are ejected. It has become. (C) is an electronic circuit, including a safe ball detection sensor (S) and an auxiliary detection switch (Sl).
, Solenoid (Foundation), Prize Ball Ejection Detection Switch (S2
) are connected respectively, and the safe ball detection sensor (S)
Counting the number of safe balls from the sensor (S), instructing the solenoid (B) to operate in response to a signal from the safe ball detection sensor (S), counting the number of prize balls discharged from the prize ball discharge detection switch (S2), and It performs calculations with the number of safe balls and digitally displays the number of remaining safe balls. In addition, in the figure, 04) is a prize ball supply tank, (15) is a prize ball supply passage, 06) is a prize ball discharge passage, and 07) is a ball extraction passage.

With the above configuration, when a ball that rolls down the game board enters the 7-7 ball receiving slot after a period of time and becomes a safe ball, the safe ball detection sensor (S) detects this and prizes it as a prize. The driving solenoid (B) of the ball ejector (B) is activated to cause the swing gutter (8) to swing back and forth to smoothly eject the prize ball and replenish the next prize ball. If the number of safe balls becomes a safe ball continuously, the number of safe balls that will not eject a prize ball is stored in the electronic circuit (C). After that, the number of prize balls is displayed digitally, and the number of prize balls is sequentially operated to eject the prize balls, and the number of safe balls and the number of times of ejection of prize balls are added and subtracted to always match.

As explained above, this invention uses a sensor to detect safe balls sent out from a safe ball collecting path and rolling through a safe ball detection path, and activates a drive device for a prize ball ejector via an electronic circuit. One safe ball performs seven prize ball ejection operations, and the number of safe balls and the number of prize ball ejections are calculated and matched using an electronic circuit, so the process from detecting a safe ball to ejecting a prize ball is easy. The series of operations can be carried out sharply and reliably, and there is no occurrence of malfunctions such as ball jams as with conventional ones.In addition, the number of safe balls and the number of times the prize balls are ejected are calculated and matched by an electronic circuit, so it is always easy to operate. This has the effect of allowing a fair game of pachinko.
