Description

[Detailed Description of the Invention] <Industry> Second Field of Application This invention relates to a prize ball detection device for a pachinko machine for detecting winning balls entering a winning device provided on the surface of a game board.

(Prior Art) A conventional detector for detecting winning balls entering a winning device is attached to the rear surface of a game board, with the detection section at the tip facing the flow path of winning balls provided in the winning device.

<Problems to be Solved by the Invention> However, with the conventional structure described above, it is easy to remove the detector from the back side of the game board, and the welded part between the terminal and the lead wire protruding from the rear end of the detector may be melted. Lead wires can be cut. In such a state, the detector does not function properly and cannot detect the winning ball that has entered the winning device.Therefore, in a winning device where the winning state of the ball changes depending on the number of winning balls that have entered the winning device, no winnings are possible. It becomes impossible to change the state, and a state advantageous to the player continues, resulting in a large number of prize balls being ejected. In particular, in pachinko game parlors that want to prosper by giving large profits to players, they operate the above-mentioned detector on the back of the game board at the time of closing in order to provide services to the players. As a result, the pachinko player's desire to play pachinko deteriorates, and he cannot hope for a healthy start to pachinko games.

The unreleased IN+ was proposed in consideration of the above, and the front face of the detector faces the flow path in the winning device installed on the surface of the mining board. The detector is housed in a detector box that opens, a lead wire is connected to the terminal protruding from the rear end of the detector, an electrical security circuit is connected to the lead wire, and the detection part of the detector is inserted into the detector box. By protruding from the open front end, the detector cannot be removed from the back of the game board or the lead wires cannot be cut.

<Example> The present invention will be described below with reference to the embodiments shown in the drawings.The winning ball detection device 211 of the present invention has a thin plate-shaped detector 4 having a non-contact detection part 3 shown as a through hole 2 at the tip. and a detection box 5 that houses the detector 4.

The above-described detector 4 magnetically detects when a pachinko ball passes through the through hole 2, and a signal is generated from a lead wire 7 connected to a terminal 6 protruding from the rear end.

The detector box 5 described above has a bottom part 8, left and right side parts 9 standing upright from the bottom part 8, an upper part 10 extending between the upper ends of the left and right side parts 9 and parallel to the bottom part 8, and a rear part 8. A storage chamber 12 for the detector 4 is formed inside the detector 4 and surrounded by each surface, and the front surface of the storage chamber 12 is open. The left and right sides of the bottom part 8 extend laterally from each side part 9, and an upright plate 13 is provided at the extending left and right side ends, and a mounting plate 14 is provided laterally at the upper end of the upright plate 13. For example, it is fixed to the back of the game board of a pachinko machine.

In the embodiment shown in the drawings, the storage chamber 12 is horizontally long and accommodates three detectors 4.
can be fitted horizontally in parallel, and the bottom part 8
A partition piece 15.15 for supporting each detector 4 is provided in an upright manner.

On the other hand, in the rear section 11 described above, one wiring hole is provided for each detector 4.
6 will be established. A lead wire 7 connected to the terminal 6 of the detector 4 fitted in the storage chamber 12 is passed through the wiring hole 16 and extended to the outside. Therefore, since three detectors 4 can be stored in the storage chamber 12, three wiring holes 16 are also formed in the rear surface portion 11. However, wiring hole 1
6 may be provided approximately at the center of the rear surface portion, and the lead wires 7 of the respective detectors 4 may be collectively extended from this wiring hole 16 to the outside.

An electrical security circuit (not shown) is connected to this lead wire 7, and when the lead wa7 is cut or the lead wire 7 is removed from the terminal 6, an alarm lamp lights up or a buzzer sounds.

When each detector 4 is stored in the storage chamber 12, the detection part 3 protrudes from the open front end of the storage chamber 12, and the detector 4
The terminal 6 is located inside the storage chamber 12 and does not protrude rearwardly from the wiring hole 16 of the rear surface portion 11. Therefore, the detector 4 can only move forward of the detector box 5, and since the connecting part between the lead wire 7 and the terminal 6 is located inside the detector box 5, this part can be moved to the front of the detector box 5. It is not possible to simply remove the detector 4, and furthermore, if the lead wire 7 is cut, the lamp will light up or the buzzer will sound as described above, so the detector 4 cannot be removed from the winning device.

The winning ball detection device Ml of the present invention has the configuration described in "-",
This winning ball detection device 1 is attached to the back surface of the game board A of the pachinko machine, and the detection part 3 of the detector 4 is made to face the flow path inside the winning device 17 provided on the surface of the game fiA.

As an example of the winning device 2117 described above, TL technique i
A horizontally elongated prize opening 19 below the substrate 18 fixed to the surface of A
An opening/closing plate 20 for opening and closing the prize opening 19 is operated by a solenoid 21 provided on the back side of the game board A.

The opening/closing plate 20 is pivoted to the lower edge of the winning opening 19 and is attached to the entrance opening 19.
Similarly, the suppressing portion 22, which is long in the horizontal direction and provided at the minus side end, faces a tiltable lock lever 23 connected to a solenoid 21 provided on the back surface of the game board A. and,
When the solenoid 21 is demagnetized, the lock lever 23 presses the suppressing part 22, so the opening/closing plate 20 is in an upright state and closes the winning opening 19. However, when the solenoid 21 is energized, the lock lever 23 is disengaged from the suppressing part 22, so the opening/closing plate 20 falls forward and opens the winning opening 19. enter.

The back side of the board 18 has a guide frame 24 which is open at the bottom and surrounds the winning hole 19, and the inside of this guide frame 24 constitutes a channel 25 for guiding the winning balls that have entered the winning hole 19. There is. And, the ending I mentioned above! II's winning ball detection device 1 is attached to the back of the game board A, but each detection "JA4
The detection unit 3 is located at the lower end of the recording channel 25, that is, the guide frame 24.
It is located on the open bottom surface of the Furthermore, there are two vertical guide ribs 26 on the inside of the rear surface of the guide frame 24, and each guide rib 26
partitions each detection section 3 of the three detectors 4. Therefore, the batted ball that enters the winning prize 1]19 enters the flow path 25 and passes through the detection section 3 of one of the detectors 4 by the guide rib 26, and when it passes through the detection section 3, it passes through the detection section 3 of one of the detectors 4.
is detected and a detection signal is generated. Further, the batted ball that has passed through the detection section 3 of the detector 4 is guided to the back side of the game board A and becomes a prize ball, and a certain number of prize balls are discharged to the player.

Basically, the winning device 17 used in the present invention only needs to have the winning hole 19 and the opening/closing plate 20 described above, but in the embodiment shown in the drawings, there is a winning hole 27 for hitting the ball above the surface of the base plate 18. Each has a display section 28 with three 7-segment LEDs arranged horizontally in the center, guide materials 29 located above the left and right of the winning hole 19, etc., and the surface is appropriately decorated. There is a decorative plate 30 in front. Therefore, when a batted ball enters the winning hole 27, it becomes a winning ball and a certain number of prize balls are ejected to the player. Even if you pass through the front, there is a prize opening 19
Instead, they flow down the game board and into other winning devices, or into the exit.

However, when a ball hits a specific winning hole (not shown) provided on the surface of the game fiA, the display section 28 is activated.
When the operation of 8 is completed and a specific mode is reached, solenoid 2
1 is excited, the opening/closing plate 20 tilts forward to widen the prize opening 19 as described above, and the batted ball flowing down the surface of the game board A lands on the opening/closing plate 20 and enters the prize opening 19. Become. Then, the batted ball that enters the winning hole 19 is detected and counted by one of the detectors 4 as described above,
When the count is 10, the solenoid 21 is demagnetized and the opening/closing plate 2
0 is in an upright state and the ball does not enter the winning hole 19. However, if the ball passes through the detection part 3 of the central detector 4 and is detected before counting 10, the solenoid 21 is demagnetized and immediately energized. , the opening/closing plate 20 tilts forward and the prize opening 19 opens again, making it easier for a batted ball to enter. The maximum number of times the solenoid 21 can be repeatedly energized and demagnetized is 10 times.

Detection window 4 described above. Solenoid 21. The electrical control by the display unit 28 etc. is operated by an electrical control device (computer) provided on the back side of the game board A, and the operation mode described above is one example, and the present invention is limited to the above example. It is not something that will be done.

Furthermore, in the embodiment described in E, the case where three detectors are housed in the detector box has been described, but the present invention is not limited to the number of detectors, and can be selected as appropriate depending on the structure of the winning device. do it.

Another embodiment of the present invention shown in FIGS. 6 and 7 includes a detector box 5 having a bottom part 8, left and right side parts 9, 9 extending directly from the left and right side edges of the bottom part 8, and both side parts 9. It consists of an upper surface part 10 between .
Three detectors 4 can be housed in parallel inside the detector box 5. When each detector 4 is housed in the detector box 5, the detector 3 protrudes from the open front end of the detector box 5. Wiring holes 16 are formed in the rear surface portion 11 in correspondence with the respective detectors 4, and when the detector rA4 is housed in the detector box 5, the terminals 6 extend outside from the wiring holes 16. Therefore, when the connector 31 is provided at the tip of the lead wire 7' and inserted into the end f6, and the intermediate terminal 32 provided at the rear end of the lead wire 7' is connected to the electrical control device; If the detector box 5 is fixed to the back side, the detector 4 will not come off, and if the lead wire 7' is cut or the connector 31 is disconnected from the terminal 6, the electrical security circuit of the electrical control device will activate and issue an alarm. In a game parlor, it is not possible to perform an operation that would cause the detection function to be lost.In this embodiment as well, when the detection atmosphere box 5 is fixed to the back of the game board, the detection part 3 of each detector 4 can be used as a winning device. Since it faces the flow path 25 of No. 17, it is possible to count each batted ball entering the winning device 17 and supply a signal to the electric control device.

In addition, in both of the above-mentioned embodiments, if the screws etc. for fixing the detector box to the back of the game board are related to parts of the winning device, even if the detector box is removed from the back of the game board, the parts etc. Since the detector will come off or disassemble at the same time, it is impossible to easily remove the detector from the back of the game board at a game parlor.

(Effects of the Invention) In summary, according to the present invention, a detector is housed in a detector box with an open front, the detection part of the detector is made to protrude from the open front end of the detector box, and the detector is made to protrude from the open front end of the detector box. Since the lead wire connected to the terminal at the end is connected to the electric security circuit, once the winning ball detection device of the present invention is attached to the back of the game board, it becomes difficult to remove and the detector loses its function. Therefore, it is possible to reliably count the number of balls that enter the winning device, and prevent pachinko parlors from dishonestly giving players unreasonable winning balls by removing the detector from the back of the game board or cutting the lead wire. can be prevented. In addition, since the player is not given an excessive amount of prize balls, the game does not encourage the player's desire to shoot, and it is possible to bring about the interest and development of the pachinko game at large.
