Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a winning ball detecting device for a pachinko machine, which is provided on a mechanism board on the back surface of the main body of the pachinko machine and detects a winning ball won on a game board.

[0002]

[Prior Art]

 Generally, in a pachinko machine, a mechanism board provided on the back of the main body of the pachinko machine detects a winning ball that has won a prize on a game board, or a predetermined number of balls based on the detection of this winning ball detector. It is configured by incorporating a prize ball discharging device for discharging prize balls.

Conventionally, as the winning ball detecting device of this type, the devices shown in FIGS. 6 and 7 have been provided. That is, the mechanism board is integrally provided with a collecting gutter 1 in which the winning balls A, which have won the winning holes of the game board, are guided in a line, and further downwardly in succession to the end portion of the collecting gutter 1. A discharge gutter 2 extending straight is provided. A rotary piece 3 is rotatably provided at the terminal end of the collecting trough 1, and a movable iron piece 5 which is swingable right and left by a solenoid 4 is provided below the rotary piece 3.

Thus, when the solenoid 4 is cut off, as shown in FIG. 6, the movable iron piece 5 projects into the discharge gutter 2 by the force of the spring 6, and the lowermost winning ball A flowing down the collecting gutter 1 is discharged. It is prohibited to fall. At this time, a proximity sensor 7 is provided at the upper end portion of the discharge gutter 2 so as to detect the winning ball A at the lowermost end thereof. At this time, the rotating piece 3 is retracted from the collecting trough 1. The proximity sensor 7 has an annular detection part having a slightly larger inner diameter than the winning ball A, and detects that the winning ball A made of a magnetic material has passed inside the detecting part.

When the solenoid 4 is energized, as shown in FIG. 7, the movable iron piece 5 is attracted and displaced to the right, and one winning ball A is discharged by dropping the discharge trough 2. A part of the rotating piece 3 enters the collecting trough 1 to lock the winning ball A located second from the bottom. By repeating the disconnection of the solenoid 4 as described above, the winning balls A flowing into the collecting gutter 1 are discharged while being counted one by one.

[0006]

[Problems to be solved by the device]

 However, the above conventional configuration has the following problems. That is, first of all, since two parts of the rotating piece 3 and the movable iron piece 5 are used to discharge the winning balls A one by one, the number of parts increases and the structure becomes complicated, and their position adjustment, etc. Since it is also necessary, the assembly work was troublesome.

The winning ball A located second from the bottom in FIG. 6 stands by in a state immediately above the proximity sensor 7, so that the winning ball A located at the bottom end is discharged. Even in the state shown in FIG. 7, there is a possibility that the proximity sensor 7 detects the next winning ball A, resulting in erroneous detection, and the detection reliability is poor.

Moreover, since the rotating piece 3, the solenoid 4, the proximity sensor 7 and the like are directly assembled to the mechanism board, the assemblability is poor and it is a check whether the operation is performed accurately. The work cannot be performed unless all the parts are assembled to the mechanical panel, and the work of replacing the defective part is extremely troublesome.

The present invention has been made in view of the above circumstances, and an object thereof is to simplify the structure and to reliably detect a winning ball, thereby improving reliability. An object is to provide a winning ball detection device for a pachinko machine.

[0010]

[Means for Solving the Problems]

 The winning ball detecting device of the pachinko machine of the present invention is a case that is detachably mounted on the mechanism board and that the winning balls are continuously introduced in an aligned state at the end of the collecting gutter provided in this case. And a winning ball detecting section which is continuous with the trailing end of the introducing path and into which one winning ball flows in from the introducing path, and the winning ball detecting section which is continuously provided below the winning ball detecting section. The discharge path for discharging the winning ball that has flowed into the outside of the case, the blocking wall and the cutout are provided at the top and bottom, and the cutout is located at the prizeball detecting section. Discharge that can move up and down between the upper position that allows the inflow of prize balls and the lower position where the blocking wall blocks the prize ball detection part and the notch is in the prize ball detection part and sends the prize ball to the discharge path Member, a drive mechanism provided in the case for moving the discharging member up and down, and the guide of the winning ball detecting section. The road has a feature where the comprising a proximity sensor for detecting that a winning ball is flow Type was in the winning ball detection portion provided opposite.

[0011]

[Action]

 According to the above means, the driving mechanism moves the discharging member up and down, and when the discharging member is at the upper position, the notch of the discharging member is located at the winning ball detecting portion continuous to the terminal end of the introduction path, As a result, one winning ball at the lowermost end of the winning balls guided in the introduction path in an aligned state flows into the winning ball detecting unit. At this time, the winning ball that has flowed into the winning ball detecting unit is detected by the proximity sensor provided on the side opposite to the introduction path of the winning ball detecting unit.

Then, when the discharging member is moved to the lower position, the blocking wall portion of the discharging member closes the winning ball detecting portion to prevent the winning ball from flowing in from the introduction path, and is located in the winning ball detecting portion. Only one winning ball is sent to the discharge path by the notch and discharged to the outside of the case. At this time, since the winning ball does not flow into the winning ball detecting unit, the proximity sensor does not detect the winning ball.

In this case, since the winning ball is stopped and discharged by one discharging member, a simple structure can be used. When the discharge member is at the lower position, the closed wall portion closes the winning ball detection portion, so that the winning ball located at the terminal end portion of the introduction path is reliably separated from the proximity sensor. False detection can be prevented.

Further, since each member is provided as a unit in a case detachably provided on the mechanism board, the assembling work is easier than when each member is directly assembled on the mechanism board. In addition to being simple, the operation check work can be easily performed at the unit stage, and the parts replacement work becomes easy.

Thus, a predetermined number (for example, 13) of prize balls B are discharged toward the ball receiving tray. In addition, the mechanism board 12 is provided with a prize ball removal passage 21 along the right side thereof, and the prize ball B in the prize ball tank 15 or the upper prize ball passage 16 is removed from the outlet 22. It can be pulled out to the back side of the main body 11.

On the other hand, as shown in FIG. 5, a gutter cover 23 is provided on the back surface of the game board to cover the entire area where the winning ball A is led out, with a space in which the winning ball A flows down. There is. In addition, a collecting gutter 24 is provided on the lower side of the mechanism board 12 continuously with the lower part of the gutter cover 23 so that the winning balls A flow down and are collected. The collecting trough 24 extends to the right with a gentle downward slope, and guides the winning balls A to the right in a state of being aligned in a line.

Further, the mechanism board 12 is provided with a discharge gutter 25 located below the collecting gutter 24 and communicating with the outlet 22. In this case, the discharge gutter 25 is provided on the front side (the back side as a pachinko machine) in the figure with respect to the collecting gutter 24, and the collecting gutter 24 and the discharge gutter 25 are displaced in the front-rear direction. It is supposed to do.

On the mechanism board 12, a winning ball detection unit 13 is attached to the right side of the collecting gutter 24 and the discharge gutter 25 so as to be detachable by, for example, screwing. Hereinafter, the winning ball detection unit 13 according to the present embodiment will be described in detail with reference to FIGS. 1 to 4.

The winning ball detection unit 13 is configured, for example, by arranging the following members inside a transparent plastic case 26. That is, as shown in FIGS. 1 and 2, the case 26 has a thin box shape in the front-rear direction, and inside the case 26, there are an introduction path 27 through which the prize balls A are introduced in a line and a prize. A discharge passage 28 for discharging the ball A is integrally provided.

Of these, as shown in FIGS. 3 and 4, the introduction path 27 is formed from the introduction port portion 27 a that is open at the left wall portion of the case 26 at the upper left portion on the inner side of the case 26. It is installed so that it extends to the right with a gentle downward slope. As shown in FIG. 5, in the introduction path 27, when the winning ball detection unit 13 is attached, the introduction port portion 27a is continuous with the end portion of the collecting trough 24. In addition, in the introduction path 27, the tip portion (termination portion) is closed at the right side, and an opening 27b through which one winning ball A located at the tip portion flows out forward is formed. Has been done.

On the other hand, the discharge passage 28 extends at a lower left portion on the front side in the case 26 while gently sloping downward to the left, and the tip portion thereof extends to the discharge port portion 28 a of the left wall portion of the case 26. It is provided so as to open. As shown in FIG. 5, the discharge path 28 communicates with the discharge gutter 25 when the winning ball detection unit 13 is attached. The base end portion of the discharge passage 28 is opened to the right and upward, and the upper portion of the base end portion serves as the outlet portion of the winning ball A from the opening portion 27b of the introduction passage 27.

Therefore, the upper part of the base end portion of the discharge path 28 and the front part of the opening 27b of the introduction path 27 serves as a winning ball detecting section 29 into which one winning ball A flows. It As a result, the winning ball A introduced to the right in the introducing path 27 flows into the winning ball detecting section 29 in front of the opening 27b at the terminal end of the introducing path 27, and the downward direction from here. After dropping into the discharge path 28, the discharge flow 28 is discharged to the left and flows in that order.

A discharge member 30 for discharging the winning balls A 1 one by one is provided inside the case 26, on the right side of the discharge path 28. As shown in FIG. 1 and FIG. 2, the discharging member 30 has a substantially fan-shaped plate shape with a rounded shape that expands to the left, and the winning edge is located at the lower half of the left edge thereof. A cutout portion 30a having a size in which A is loosely fitted is formed, and an upper portion of the cutout portion 30a is a closing wall portion 30b. Further, an operating portion 30c is provided at the right end of the discharging member 30.

The discharge member 30 is pivotally supported on the case 26 via a shaft 31 extending in the front-rear direction at the right end portion thereof. As a result, the discharge member 30 has an upper position where the cutout portion 30a is located in the winning ball detecting portion 29, as shown in FIGS. 1 and 3, and a closed wall portion 30b as shown in FIGS. 2 and 4. Is located in the winning ball detecting section 29, and the notch 30a is vertically swingable between the notch 30a and a lower position located at the base end of the discharge path 28.

A solenoid 32 as a drive mechanism for swinging the discharging member 30 is provided at the right end portion of the case 26. The solenoid 32 has a downward facing plunger 32a, and its tip end is connected to the operating portion 30c of the discharge member 30, so that the solenoid 32 is turned on and off, whereby the plunger 32a appears and disappears. And the discharge member 30 swings between an upper position and a lower position.

Further, the case 26 is provided with a proximity sensor 33 for detecting the winning ball A. The proximity sensor 33 has a planar detecting portion, and as shown in FIGS. 3 and 4, the case 26 is located on the side opposite to the introduction path 27 of the winning ball detecting portion 29, in this case, on the front side. It is attached to the outer wall of the winning ball A and magnetically detects the winning ball A flowing into the winning ball detecting unit 29.

The winning ball detection unit 13 configured as described above is attached to the mechanism board 12 by, for example, screwing, and at this time, as described above, the introduction path 27 is continuous to the end portion of the collecting trough 24. The discharge path 28 is continuous with the discharge gutter 25. Further, a lead wire (not shown) led out from the case 26 makes an electrical connection with the control device, the solenoid 32 is turned on and off by the control device, and the detection signal of the proximity sensor 33 is input to the control device. It is supposed to be done.

Next, the operation of the above configuration will be described. When the game is started and the winning on the game board is started, the winning balls A are collected in the collecting gutter 24 and are introduced in a line in the introducing path 27 of the winning ball detecting unit 13. The discharge member 30 is configured to keep the upper position at all times (when the power is cut off), and the first winning ball A flowing down the introduction path 27 is immediately detected as shown in FIGS. 1 and 3. It flows into the notch 30 a of the discharge member 30 forming the portion 29 and is detected by the proximity sensor 33. The control device controls the prize ball discharging unit 17 based on the detection signal generated by the proximity sensor 33, and discharges a predetermined number (for example, 13) of prize balls B for the winning. On the other hand, the control device also energizes the solenoid 32, which is the drive mechanism of the winning ball detection unit 13, to rotate the discharging member 30 to the lower position, so that the winning ball A held in the notch 30a is discharged to the discharging path 28. To release.

During this time, the winning ball A that has flown in the second and subsequent prizes is blocked by the closing wall portion 30b of the discharge member 30 that has rotated to the lower position in the upstream direction from the tip opening portion 27b of the introduction path 27. Has been made. Then, when the discharge of the prize ball B is completed, the discharge member 30 automatically returns to the upper position by cutting off the power supply to the solenoid 32 which is the drive mechanism, and the discharge member 30 is connected to the tip opening 27b of the introduction path 27. Since the cutout portion 30a of the discharging member 30 relatively faces each other, the earliest one of the waiting prize balls A can flow into the prize ball detecting unit 29.

After that, when the discharging member 30 is swung again to the lower position, the closing wall portion 30b closes the winning ball detecting section 29 and blocks the inflow of the winning ball A from the introduction path 27 as described above. At the same time, one winning ball A that was in the winning ball detection unit 29 is sent to the lower part by the notch 30b, is discharged toward the left in the discharge path 28, passes through the discharge gutter 25, and is discharged from the outlet 22 to the main body. It is discharged to the outer back surface side of 11.

By repeating the above operation, the winning balls A are detected one by one, and the winning balls B corresponding to the number of winning balls A are discharged based on the detection.

According to this embodiment, the following effects can be obtained. That is, First of all, since the winning ball A is stopped and discharged by one discharging member 30, the winning ball A is stopped and discharged by the conventional two members of the rotating piece 3 and the movable iron piece 5. The number of parts is reduced, and the structure is simplified, unlike the case where the output is performed.

When the discharge member 30 is in the lower position, the closing wall portion 30b closes the winning ball detecting portion 29, so that the winning ball A and the proximity sensor 33 located at the terminal end of the introduction path 27 are separated from each other. Since they are reliably separated from each other, unlike the conventional one in which the proximity sensor 7 may cause an erroneous detection, the proximity sensor 33 does not cause an erroneous detection. As a result, the winning ball A can be reliably detected, and the reliability thereof is significantly improved as compared with the conventional one.

Further, since the mechanism for detecting the winning ball A is incorporated into the case 26 to be unitized, compared with the case where each member is directly attached to the large mechanism board 12, one by one. Assembling workability is improved. At the same time, for example, when manufacturing a pachinko machine, the work of checking the operation can be performed at the stage of assembling the respective parts into the case 26 before the mechanical board 12 is mounted, and the check work becomes easy. .. In addition, even if there is a failure, the winning ball detection unit 13 can be easily removed from the mechanism board 12 for repairs, etc., and the winning ball detection unit 13 can be used even when it cannot be repaired. Since only the replacement is required, the work can be easily performed.

The present invention is not limited to the embodiments described above and shown in the drawings, and deviates from the gist of the present invention, for example, various modifications of the shape of the discharging member and the driving method thereof can be considered. It can be implemented by appropriately changing it within the range not to do.
