Description

[Detailed Description of the Invention] The present invention relates to a device for eliminating the bridge-like blockage of balls in the path of a pachinko machine.

The back panel of the pachinko machine's peg plate shows safe balls (balls that enter the safe hole), prize balls (balls that are paid out for each safe ball), and out balls (balls that enter the out hole) along a predetermined path. Accordingly, there are troughs or passages to transport the water under its own weight. These gutters and passages do not all have a constant width; for example, the receiving part for storing prize balls is formed with a large volume, and the prize ball passage connected to it has a narrow width. In addition, the safe ball gutter is configured to receive the safe balls that have entered each safe hole all at once, and the subsequent safe ball passages allow the balls to pass through one by one so that each safe ball can be detected and counted one by one. It's about the same width.

In such a connecting part, for example, a connecting part between a prize ball receiving part and a prize ball passage, a large number of prize balls are prepared in this receiving part, and all of them flow toward the prize ball passage having a predetermined width. Therefore, adjacent prize balls may interfere with each other, forming a so-called bridge at the entrance of the prize ball passage, and causing a ball jam. Also, in the connection between the safe ball gutter and the subsequent safe ball path, if many safe balls occur within a short period of time, it may take some time to detect the safe balls, count them, and pay out the prize balls. from,
A situation may arise in which safe balls are temporarily stored in this area, resulting in the above-mentioned ball jam due to the bridge.

The present invention was developed with the aim of automatically dissolving the ball jam caused by the so-called bridging as described above, and its basic components include a bridging clearing plate whose displacement is driven by an electromagnetic device such as a solenoid; The apparatus is comprised of at least two detection means for detecting the presence or absence of pachinko balls in the vicinity of the elimination board, and a control section for driving and controlling the electromagnetic device according to the output states of both of the detection means.

An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 shows an example of the configuration of the nail plate back panel of a pachinko machine to which the present invention is applied, in which 1 is a base plate, 2 is a receiving part for storing a large number of prize balls, 5 is a safe ball gutter, and Safe holes 5 appropriately provided on the front panel of the board
It is designed to receive a safe ball that lands 0. The prize balls stored in the receiving part 2 are normally sent by their own weight through the prize ball passage 20 to the prize ball payout part 21, and when a safe ball is generated, the payout machine 21 sends out a predetermined number of prize balls to the prize ball payout part 22. After being sent out, a predetermined number of prize balls are stored in this payout device 21 again. Note that 23 is a winning bell that is rung by the paid out prize balls, 24 is an upper prize ball payout opening opened to the front panel of the nail board, and 25 is an upper tray installed on the front panel side. Further, when the upper tray is full of prize balls and it becomes impossible to pay out the prize balls from the upper prize ball dispensing port 24, the prize balls are paid out to the lower prize ball dispensing port 26 and the lower tray 27. 28 is a dispensing operation lever, a spring 29,
The solenoid 30 causes the solenoid 30 to make one reciprocating motion, thereby causing the payout section 21 to perform one prize ball payout operation. The solenoid 30 is actuated every time the safe ball is counted, as will be described later, and the photo sensors P1A and P1B detect the completion of one reciprocating movement of the operating lever 28, that is, the completion of the prize ball payout process. This photo sensor P1A, P1
For example, a reflective type having a light projecting part and a light receiving part is used as B, and the light reflected from the end surface of the actuating lever 28 is detected. Therefore, it can be confirmed that the actuation lever 28 has reliably made one reciprocation since the sensor P1A detects the reflected light and then the sensor P1B detects the reflected light. A safe ball passage 51 is further connected to the safe ball gutter 5. This safe ball passage 51 has a width that allows one pachinko ball to pass through, and a photo sensor P2 consisting of a light projecting part and a light receiving part is provided in the path of the passage, and a photo sensor P2 that allows one safe ball to pass therethrough is provided. Count each piece. This count signal is integrated into a counting circuit controlled by the CPU, and also operates the solenoid 30 that pays out the prize ball via the CPU.
Each time one prize ball payout process is detected by the aforementioned photo sensors P1A and P1B, a subtraction is made from the integrated value of the counting circuit, and when the integrated value of the counting circuit reaches the initial value, the prize ball payout process is completed. do. Needless to say, this cycle is repeated while the game continues.

A branch path 33 branched from the prize ball passage 20 is a ball removal path, and the prize balls in the receiving portion 2 can be collected by a ball removal solenoid 34 and a movable plate 35. Also, by the solenoid 36 and claw 37,
The flow of prize balls in the prize ball passage 20 can be temporarily stopped and used for inspection and other purposes.
The photo sensor P8 is a pachinko ball detector for preventing prize balls from accumulating in the lower tray 27 to a certain extent and overflowing into the inside of the pachinko machine.

P3 to P6 are photo sensors for checking the flow of pachinko balls in the respective passages, and are composed of a light projecting part and a light receiving part facing each other through a light transmitting part formed in each passage. Reference numerals 60 and 70 designate a bludge-resolving plate in the prize ball passage and a bludge-resolving plate in the safe ball gutter, respectively, and these are swung to the dotted line position by solenoids 62 and 72 about shafts 61 and 71, respectively. Note that when the solenoids 62, 72 are in a rest state, the bridge eliminating plates 60, 70 are in the solid line position shown in the figure, forming a pachinko ball passage.
The operation of the bridge elimination plates is controlled via the CPU in response to pachinko ball detection signals from the respective photo sensors.

FIG. 2 is a flowchart relating to the operation of the bridge eliminating plate, and one example thereof is shown for the bridge eliminating plate 60 of FIG. In the judgment process in this chart, each photo sensor P
Regarding 3 and P4, an "H" signal is output when the presence of a pachinko ball is detected.
As is clear from FIG. 2, if there are pachinko balls above the prize ball path but not below, sensor P3 becomes "H" and sensor P4 becomes "L". ”, a ball jamming signal is output, and the solenoid 62 is driven by this. When the solenoid 62 is driven, the bridge elimination plate 60 in FIG. 1 swings to the position indicated by the broken line, so that the pachinko balls that have entered the bridge state are forcibly moved and the bridge state is eliminated. Note that the solenoid 62 is driven until the ball is no longer clogged and the sensor P4 outputs an "H" signal.

Further, when the sensor P3 does not output an "H" signal, it means that the prize balls are out of balls, and a prize ball replenishment signal is output.

Incidentally, the bridging elimination plate 70 provided in the safe ball gutter 5 is also controlled in the same manner as in the above-described flowchart. In this case, the judgment by the sensor P3 and the prize ball replenishment signal generation process are omitted,
This can be considered by replacing sensor P4 with P2.
Further, the sensor P6 is used in combination with a timer circuit or the like so as to generate an "H" signal when the presence of a pachinko ball is detected continuously for a predetermined period of time or more.

Figure 3 is a functional diagram for explaining various control processes including the ball jam elimination process.
controlled by. In FIG. 3, the photo sensors P3, P4, P6, their processing by the CPU, and the operation of each solenoid are as described above. In addition, each photo sensor P5, P2,
Each process shown in the figure is performed by P1A and P1B.
For example, if the photo sensor P5 does not detect a pachinko ball, it means there is a problem, and the warning lamp lights up.
The motor M for launching pachinko balls is stopped. In addition, the photo sensor P2 counts the safe balls and displays the counted value digitally using a 7-segment LED. When the prize ball is paid out, a subtraction process is performed from the above-mentioned count value based on the payout confirmation signal obtained by the photo sensors P1A and P1B.

FIG. 4 shows another embodiment of the bridge elimination plate and photo sensor in the prize ball passage.
The difference from the previously described embodiments is that instead of the rocking plate 60, a sliding plate 80 having a central opening 81 of approximately the same size as the passageway is used as the bridging elimination plate, and that the photo sensor P4 uses reflected light. The reason is that a detection type photo sensor is used, and the operation control of the solenoid 62 is the same as in the previous embodiment. In this embodiment, when the sliding plate 80 moves, it hooks the ball at the opening 81 and moves it, so bridging is eliminated. In addition, the sliding plate 8
0 need not necessarily be installed horizontally, and may also be placed between the sensors P3 and P4. Furthermore, a combination of a motor and a cam may be used as a drive device for eliminating bridges.

As can be understood from what has been said above,
According to the present invention, it is possible to automatically detect the ball jamming phenomenon caused by bridging that tends to occur in various parts of the pachinko ball path or gutter, especially in places where the path width suddenly narrows and the flow of pachinko balls is restricted. ,
This can be resolved.
