Description

[Detailed Description of the Invention] This invention relates to a pachinko ball detection unit for detecting balls such as safe balls or out balls in a pachinko machine.

That is, an object of the present invention is to provide a pachinko ball detection unit that can be installed at a desired location of a pachinko machine as appropriate and easily replaced by integrating the pachinko ball detection mechanism into a unit.

Now, as a means for detecting balls such as safe balls or out balls in pachinko machines, a micro switch with a self-returning contact mechanism and a hinge lever type actuator is adopted, and the micro switch is disposed in the ball path. When the lever of the same switch facing the road came into contact with the ball, the switch operated and the ball was detected.However, with this detection technology, multiple balls continuously move the switch part at high speed. If the ball is distributed in the market, it is no longer possible to accurately detect the ball.

In other words, when a plurality of balls successively pass through the path 31 at high speed as illustrated in FIG.
1 presses down the lever 33 of the switch 32 and passes, and each of the second and subsequent balls B2, B3...
Because the ball passes by pressing down the lever 33 one after another without leaving a time difference (interval) with the previous ball, the lever 3
Even if 3 is released from the leading ball, it is pressed down by the following trailing ball soon after returning to the original pre-operation (pre-detection) state.

Therefore, although the switch 32 can detect the leading ball, it cannot detect the following ball, so accurate detection cannot be expected at all.

The present invention was devised in order to solve the above-mentioned conventional problems, and consists of an actuating member facing the distribution path of the balls and capable of accurately guiding the balls one by one, connected to a detection switch. This is a detection unit that can accurately detect and operate the switch every time the ball passes through the pachinko machine.In particular, it can eliminate detection errors caused by continuous passage of multiple balls and perform accurate detection. It is designed so that it can be easily assembled.

An embodiment of the present invention will be described below with reference to the drawings. In this example, we will explain the case where it is implemented as a detection unit for safe balls, and the detection unit C itself can be installed at any desired position on a pachinko machine.
is mounted so as to face the ball flow path 3 in the safe ball collection cover gutter 2 mounted on the back surface of the play board 1, as illustrated in FIG. In FIG. 1, 4 indicates a lead-out path for safe balls, and 5 indicates a discharge path for out-balls.

In the detection unit C of this example, two pachinko balls are arranged in parallel with a gap through which one pachinko ball can pass.
Screw cylinders 9, 9 are fastened to the pair of rectangular first member 6 and second member 6' in an abutting state with screws 10. The first member 6 and the second member 6' each have a case 6 formed so as to protrude inward to form cases 60 which are divisibly connected to face each other.
Mounting portions 7 for attaching the 0 to a desired position on the play board with nails, wood screws 8, etc. are formed in opposite directions.

The detection unit C forms a ball circulation path in the case 60, and includes an operating lever 18 facing this path, and a detection switch 24 that is operated in conjunction with this lever 18.
are assembled into a case 60. That is, the first member 6 and the second member 6' are integrally formed by two screw cylinders 9 which also serve as stoppers, which are formed to protrude inward from the two members 6, 6', respectively, and are fastened in an abutting state by screws 10. In the case 60 connected to each other, an inlet 13 is formed on the upper surface through a partition piece 11 and a partition wall 12 to communicate with the outlet of the spherical flow path 3, and an inlet 13 is formed on the end surface to protrude inward from the lower end of the partition wall 12. Outlets 15 that can be communicated with the lead-out path 4 side by the guide protrusions 14 are formed corresponding to one ball (diameter), and further, a ball passage 16 that communicates the inlet 13 and the outlet 15 is formed. It is formed. Note that the interval between the lower end of the partition piece 11 and the inner end of the guide protrusion 14 is the entrance of the ball passage 16 and is slightly larger than the diameter of the ball. Reference numeral 17 denotes a recessed hole formed at the entrance 13 of the case 60, and a wall portion 17a surrounded by this recessed hole 17 and connecting only both ends of the upper edge to the first and second members 6, 6', respectively, can be inserted as needed. By cutting it out, a lateral inlet can be formed which can communicate with the inlet 13.

The operating lever 18 is a member that has both an intermittent ball feeding function of receiving and discharging balls one by one and an operating function for the detection switch 24, and its base end is connected to a pin 19 between the first and second members 6 and 6'. A circular ball receiving part 20 located in the above-mentioned ball passage 16 is formed at the free end, a stopper piece 21 is provided at the upper end of the receiving part, and a guide piece 21 is provided at the lower end of the receiving part. The pieces 22 are formed and arranged at an obtuse angle (approximately 100 degrees) to each other, and an operating piece 23 for the rod 25 of the detection switch 24 fixed in the switch housing 27 on the opposite ball path side is formed at the base end. are doing.

The actuating lever 18 is tilted by the weight of the ball, and before actuation, the rod 25 of the detection switch 24 holds the guide piece 22 in an upwardly tilted state in contact with the lower end of the guide protrusion 14. It is held stationary so that the ball receiving part 20 is directed toward the entrance 13, and when receiving the ball, the guide piece 22 is placed in a substantially horizontal position (case 6
0) to narrow the entrance and exit sides of the ball passage 16, and after passing through the operating position for the switch, it is operated to the downward tilted state stopped by the stopper screw cylinder 9, and the ball receiver is The part 20 is in a spherical outflow state directed toward the outlet 15.

The detection switch 24 is, for example, a microswitch with a self-resetting contact mechanism and a push-button actuator, and when the rod 25 is pushed from the free position to the operating position within the tilting range of the operating lever 18 described above. It is set to turn ``ON'' at this point, and turn ``OFF'' to send a detection signal when the sensor returns to the return position from the position after the subsequent operation. Note that the switch 24 is connected to the lead wire 26.
is connected to a counter (not shown) that calculates the number of detection operations (ball count).

Therefore, in this example unit configured as described above, the actuating lever 18 receives the safe ball B that has entered the inlet 13 of the detection unit C from the ball flow path 3 in the collection cover gutter 2 into the ball receiving portion 20. The switch 24 is immediately tilted downward, and while pushing in the rod 25 of the detection switch 24 with the operation piece 23, the switch 24 is moved to the operating position.
After turning "ON", the safe ball B is rolled on the guide piece 22 at the ball outflow position and is caused to flow out from the outlet 15 to the lead-out path 4 outside the unit C. The actuating lever 18, which has been released from the ball as a result of this, is returned to the ball receiving position in an upwardly tilted manner under the biasing force that accompanies the return of the rod 25. In this way, the detection switch 24 similarly performs the detection operation in connection with the operation of the operating lever 18 thereafter.

This example unit is based on this detection operation,
Detection of a plurality of safe balls continuously flowing down the ball flow path 3 can be performed accurately as follows. For convenience, each safe ball is given a subscript (Arabic numeral) and explained with reference to FIG. 5. First, the operating lever 18 that has received the leading ball B1 is tilted downward to the operating position as shown in FIG. 24 is turned ON, the entrance side of the ball passage 16 is already in a narrowed state due to the asymptotic descent of the restraining piece 21 relative to the guide protrusion 14, while the exit side is already in a narrowed state due to the asymptotic descent of the restraining piece 21 relative to the guide protrusion 14. Since the leading ball B1 is still in a narrowed state due to the middle stage, the leading ball B1 is prevented from flowing out by the guide projection piece 14 and is positioned on the guiding piece 22, and the following ball B2 cannot enter the ball passage 16 and the leading ball B1 It is located inside the entrance 13 while being in contact with the.

When the actuating lever 18 is tilted downward to the ball outflow position as shown in FIG. 15 to the outside of the detection unit C. When the lever 18 is in the downwardly tilted state, the stopper piece 21 is closest to the guide protrusion 14, so that the next ball B2 can be moved by both pieces 14,
The ball is prevented from flowing into the ball passage 16 while being supported between the balls 21 and 21 . In this state, since the stopper piece 21 receives the next ball B2 with its slope, a pushing force to the right in the figure is generated, albeit slightly, as a component of the downward force due to the ball's own weight. As a result, a clockwise moment in FIG. b is acting on the lever 18.

Subsequently, when the preceding ball B1 flows out of the detection unit C, as soon as the operating lever 18 is released from the same ball B1, it immediately returns to its original ball receiving position mainly due to the urging force accompanying the return of the rod 25. It is quickly tilted upwards towards. During the return process of the lever 18, the detection switch 24 is turned OFF as the rod 25 returns to its return position. After this, the above-mentioned stopper piece 21 moves upward apart from the guide projection piece 14 to open the entrance of the ball passage 16, so as soon as the next ball B2 is released from both pieces 14 and 21, as shown in FIG. It flows into the ball receiving part 20 from the ball passage 16. As a result, the actuating lever 18 returns to its original upwardly inclined position and then is again downwardly inclined, and in conjunction with this, the detection switch 24 is again turned "ON" to perform the ball detection operation.

Thereafter, in the same manner as described above, the detection switch 24 is operated in accordance with each intermittent ball feeding operation of the actuating lever 18 from ball reception to ball outflow, and by the cooperation of both 18 and 25, the detection switch 24 is operated to detect all the safe balls. The detection operation can be performed accurately one by one (one time at a time).

In this way, in the present invention, it is possible to accurately follow and detect one by one not only when the safe balls B pass intermittently, but also when the safe balls B pass continuously. According to this technology, a movable winning machine is operated in a state that can increase the possibility of winning (occurring) a safe ball by operating a solenoid in response to a command from a counter in response to a predetermined number of detections of the switch 24. If adopted as an example, the winning machine can be activated precisely every time a certain number of safe balls pass.

The detection unit C of the present invention has an actuation lever 18 and a detection switch 24 built into a case 60 formed by connecting a first member 6 and a second member 6' facing each other with both screw cylinders 9 and screws 10. , the installation work of the detection unit C to the play board becomes extremely simple, the time required for the installation work is shortened, and the installation work efficiency is greatly improved.
This has the effect of making repairs and inspections easier.

Further, the first member and the second member each have screw cylinders that are respectively protruded inward and fastened in a butt state so that the two members face each other with a gap that allows one pachinko ball to pass through. Since both members are integrally divided into two parts and connected facing each other by a screw tube and a screw, even if a rotatable operating lever is inserted inside, the relative position and gap between the two members can be adjusted. It is possible to easily assemble both members by always keeping them constant.

In addition, since the operating lever separates the pachinko balls one by one and allows them to pass through the case without contact, it is possible to accurately detect each pachinko ball passing through the case, and the pachinko machine It is possible to eliminate the problem of erroneous detection of the number of balls caused by continuous passing through the passage in a contact state.

Furthermore, since the actuating lever forcibly changes the direction of the pachinko balls within the case, the pachinko ball detection method of the present application does not require a separate guide path for changing the direction of the pachinko balls on the back of the play board, where installation space is limited. By simply attaching the unit to a desired position on the back of the game board, it becomes possible to change the direction of the pachinko balls in the required direction and release them from within the case.

In addition, since the pachinko balls are actively released from the case using the actuating lever, there is no problem of pachinko balls staying inside the case or clogging, and there is no problem in detecting pachinko balls. .

Further, since the detection switch can be held and released by connecting and separating the first and second members, the detection switch can be easily removed and replaced in the event of a failure of the detection switch.

In addition, the detection unit C can be freely attached to any of the pachinko ball passages for game balls, safe balls, out balls, prize balls, etc., for example, facing the safe ball entrance on the game board surface. If the winning device is properly attached, the interlocking relationship of the winning device can be set in various ways.

In particular, when installing detection unit C, case 6
With the desired side of 0, the outlet 15 can be freely attached to either the left or right direction. Moreover, it is also possible to utilize the recessed holes 17 and cutout wall portions 17a of the first and second members 6, 6' to accommodate the ball from both the top and side surfaces. Incidentally, since the intermittent ball feeding operation speed of the operating lever 18 can be set by the length and inclination angle of the guide piece 22, the guide piece 22 may be provided to be adjustable in length and angle.

In this way, the present invention incorporates a detection switch that sends out a detection signal in the process of accepting and ejecting balls one by one from the ball path, and the detection mechanism is integrated into a unit, so that the detection mechanism can be placed anywhere in the pachinko machine at any desired location. This has the effect of being able to be easily attached to the device and providing compatibility to the detection mechanism. In addition, it is possible to accurately detect all balls once at a time, not only in the case of a single occurrence and distribution of balls, but also in the case of multiple consecutive occurrences or continuous distribution in a passage. be.
