Description

  The present invention relates to a winning device for a pachinko machine.

  The winning device of the pachinko machine is in the game part of the game board surface, and when a ball launched by the launching device jumps in, it has a role of connecting it as a safe ball (effective ball) and releasing a predetermined prize ball. At the same time, the winning device detects the hit of the hit ball, and uses the obtained detection signal as a start signal for the variable display device, for example, to receive the winning ball with the function of detecting the incoming ball. There is a device and it is widely used. For example, what is used as a start winning opening is an example.

  The winning device having the above-described detection function has a detection switch for detecting a passing ball (incoming ball) magnetically or optically in a ball receiving unit that receives the incoming ball, and is formed in the ball receiving unit. A ball passing through the inflow ball passage is detected, converted into an electric signal, and transmitted to the game control device, and used for the advancement of the game set in advance. Normally, this winning device has a main body part centered on a ball receiving part for receiving an incoming ball, and a detection switch for detection, and a detection switch that is separately molded on the main body part is freely attached and detached, It is completed by assembling together.

  In general, the detection switch is assembled by inserting it from the back of the mounting board prepared for fixing the main body part to the game board toward the ball receiving part provided on the front side of the board and moving the ball receiving part up and down. The ball detecting hole provided on the tip end side of the detection switch faces the penetrating ball passage that penetrates, and is mounted in communication, and after mounting, it is integrated by hooking a locking piece so as not to come out arbitrarily.

A winning device with a detection switch made in this way is often discarded when the use of the game board to which it has been installed is terminated, and in particular, those that remain in use are left as such in the new game board. It was never installed and reused. In particular, the winning device is a part of the design applied to the game board, so even if it is reused, the switch that remains in use remains a major limitation, and is actually difficult.
However, the detection switch built into this winning device is not built into the special game board design, and the service life is much longer than when the game board is discarded. Recently, the reuse of the detection switch has been specifically studied and partially implemented.

  In the conventional reuse or reuse, since this detection switch is detachably assembled to the main body portion, a method of reusing it by removing it from the main body portion and reassembling it into a new main body portion is adopted. ing. However, once the detection switch has been used, the inner wall of the sphere detection hole or the vicinity of the opening on the entrance side may be damaged or soiled by collision or contact with a passing sphere (injection sphere). After removing from the part, the state was inspected, and even if there was damage or fouling, it was avoided to use as a new product even if it was functionally defect-free.

This detection switch is often damaged or soiled by collision or contact with the passing sphere to be detected, particularly by collision or contact in the vicinity of the inner wall of the sphere detection hole or the upper opening on the inlet side. For example, a winning device is proposed in which the upper opening on the entrance side of the ball detection hole is covered to prevent a ball trying to pass through the ball detection hole from colliding with the detection switch. For example, what is described in Patent Document 1 is an example.
Japanese Patent No. 3056848. In the specification, the claims, paragraphs 0013 and 0016, and FIGS. 1 and 2 of the drawings.

  Patent Document 1 relates to a passage device of the same type as the prize-winning device according to the present invention. In the decorative cover member 30 corresponding to the ball receiving portion, an inlet opening 33 and an outlet opening 34 are formed vertically, and the inlet A covering portion 35 protrudes inward from the opening 33, and the covering portion 35 covers the upper end opening edge of the ball passing hole 41 of the passing ball detector 40 (that is, the detection switch), so that the falling hit ball passes. When passing through the mouth devices 20a and 20b, they collide with the covering portion 35 so as not to collide with the opening edges of the ball passing holes 41 of the passing ball detectors 40a and 40b.

  However, the passing-through device described in the above-mentioned patent document covers the passing ball detector, that is, the ball passing hole of the detection switch, that is, the upper end opening edge of the ball detecting hole, by the covering portion protruding from the entrance opening of the decorative cover member. Therefore, it is possible to avoid collision and contact of the passing ball with the opening edge, but contact with the inner wall surface of the ball passing hole, that is, the ball detection hole cannot be avoided. May leave a trace of the passage of the sphere. Therefore, when trying to reuse in the same state as a new article, this becomes an obstacle and it is difficult to obtain the same commercial value.

  Therefore, in view of the above-described conventional situation, the present invention completely cuts off the collision and contact of the passing ball with respect to the detection switch that is freely attached to and detached from the ball receiving portion during use of the winning device, and detects by this collision and contact. It is an object of the present invention to provide a winning device that can effectively avoid damage and contamination of a switch and can be used without renewing the value of a product in the same way as a new one upon reuse.

As is well known, the hit ball launched by the launching device is rotated by the guide rail while passing through the guide path, and the hit ball that has reached the game section falls due to the rotation being changed by the collision with the obstacle nail, etc. Therefore, not only the ball that jumps straight into the winning device, but also the ball that collides with or touches the opening edge of the ball, collides with the opposite edge while changing the rotation, or the inner wall surface of the passage hole. Or pass while touching. For this reason, in the case of a winning device equipped with a detection switch, even if the opening edge of the passage hole is covered, it is not possible to avoid contact with the inner wall surface of the ball detection hole of the detection switch. Even if not, it will leave a clear trace of use.
The present invention provides a winning device with an improved detection switch that effectively avoids traces of use left in this way and improves the detection switch after use so that it can be reused while maintaining a new state. To do.

  In order to achieve the above-mentioned object, the present invention allows a ball detection hole of a detection switch assembled to the ball receiving portion to communicate with a jumping ball passage formed in a ball receiving portion of a winning device, and In the winning device that detects the incoming ball through the ball detection hole, the upper and lower diameters of the incoming ball passage facing the upper and lower sides of the ball detection hole are limited to the diameter of the ball. The diameter of the hole is smaller than the diameter of the hole, and when the incoming ball passes through the ball detection hole, the inner wall surface of the incoming ball passage prevents the incoming ball from contacting the inner wall surface of the ball detection hole. It is to provide a winning device for a pachinko machine that is characterized by the above.

  More specifically, in the present invention, a ball receiving portion that protrudes from the front surface of the mounting substrate and has a ball-injecting ball passage is provided, and from the back of the mounting substrate toward the ball receiving portion of the ball receiving portion. A mounting hole that penetrates, a mounting receiver that is formed along an inner wall surface that is continuous with the mounting hole and surrounds the inflow ball passage, and a tip edge is engaged with the mounting receiver through the mounting hole; In a winning device for a pachinko machine comprising a detection switch for detecting a passing ball passing through the incoming ball passage by communicating a ball detection hole penetrating vertically with the incoming ball passage, the incoming ball passage is detected The inner wall portion facing the upper opening and the lower opening of the switch ball detection hole has a diameter that allows the passage of the passing ball, and has a diameter smaller than the diameter of the ball detection hole of the detection switch, A passing sphere passing through the incoming ball passage is formed on the inner wall surface of the sphere detection hole. And to provide a winning device pachinko machine is characterized in that by comprising to pass without touching.

  The ball receiving portion is formed of a synthetic resin together with the mounting substrate. Then, due to the relationship of forming the incoming ball passage in the ball receiving portion, the ball receiving portion and the mounting substrate are formed separately and completed after being molded. At this time, the ball receiving portion is provided with an intrusion ball passage which is formed so that the cross section is a U-shaped cross section and is opened rearward, and at the same time, the edge of the tip of the detection switch along the inner side, that is, the inner surface. A mounting receiving part is provided for receiving.

On the other hand, the mounting board is a fastening means for assembling the ball receiving portion to the game board, and is attached from behind the ball receiving portion to close the opening portion on the back side of the jumping ball passage, The inflow ball passage is substantially formed in a cylindrical shape.
The mounting board is provided with a mounting hole penetrating back and forth corresponding to the mounting receiving part formed in the ball receiving part, and the tip of the detection switch facing from the back of the board is passed through the mounting hole through the mounting ball. The ball receiving portion and the detection switch are assembled by inserting into the passage and finally inserting and engaging the tip edge portion of the detection switch with the mounting receiving portion.

The ball receiving portion and the mounting substrate formed separately are assembled together and fixed with screws or the like. And the detection switch assembled | attached through the mounting hole of the said mounting board | substrate is latched by the latching piece integrally provided so that it may protrude back from the back surface of this mounting board | substrate, and it mounts | wears with a removable state.
When assembling this detection switch, the ball detection hole provided in this switch is made to communicate with the incoming ball passage of the ball receiving portion so that the incoming ball from the upper entrance of the incoming ball passage can be communicated. It passes through the sphere detection hole.

The diameter of the incoming ball passage provided in the ball receiving portion is required to allow the passage of the incoming ball, but the diameter is smaller than the diameter of the ball detection hole of the detection switch facing the incoming ball passage. This prevents the incoming ball passing through from contacting the inner wall surface of the ball detection hole.
The portion of the ingress ball passage that is smaller than the diameter of the ball detection hole does not need to extend over the entire length of the passage, and only the inner wall surface facing the upper and lower openings of the ball detection hole of the detection switch. The diameter of the inner wall surface is smaller than the diameter of the sphere detection hole and has a diameter that allows the incoming ball to pass through, that is, a diameter of 11 mm or more of the diameter of the pachinko sphere.

As is apparent from the above description, the inner wall surface portion in the intrusion ball passage is most suitably provided in accordance with the position where the mounting receiving portion for mounting the detection switch is formed. If it is integrated, it is advantageous not only for easy molding but also for improving the accuracy of both.
For example, when forming the mounting receiving portion, two ridges are erected on the inner wall surface of the incoming ball passage at intervals corresponding to the wall thickness of the detection switch, and detection is performed between the ridges. While the tip of the switch can be received as a mounting receiving portion, the upper and lower protrusions are formed so that the substantial inner diameter is larger than the diameter of the pachinko sphere and smaller than the inner diameter of the ball detection hole. Then, the diameter of the incoming ball passage can be determined in accordance with the formation of the mounting receiving portion.

  By the way, in the case where the detection switch is widely put into practical use, the wall thickness thereof is about 5 to 6 mm. Therefore, the distance between the two protrusions should be adjusted to this, and the detection switch is raised in close proximity. Will do. As a result, even if the hit ball that enters the entrance ball passage collides with the edge of the opening and enters obliquely, it does not come into contact with the edges of the upper and lower ridges and contact the inner wall surface of the ball detection hole. It will pass, and the pollution accompanying contact can be avoided.

Therefore, as apparent from the above, the detection switch facing the incoming ball passage of the ball receiving portion is protected by pushing the edge of its tip into the mounting receiving portion, and at the same time, the incoming ball passage The sphere detection hole communicated with the upper and lower openings is covered by the two ridges forming the mounting receiving portion, and the inner diameter of the ridge is smaller than the inner diameter of the sphere detection hole. Since the passing ball does not come into contact with each other, and no trace is left by the contact, a new state can be maintained.
Therefore, when it is reused, it can be reused by simple processing such as wiping off dust on the surface without checking for damage or contamination, and there is no direct contact with the hit ball. Therefore, it is possible to maintain a high yield for reuse without causing any damage.

  Next, in order to clarify the present invention, the illustrated embodiment will be described. In addition, although the example disclosed here shows an example which is best for understanding and implementing the present invention, the present invention is not limited to this example.

  In the accompanying drawings, FIG. 1 is a perspective view seen from the back side of a winning device according to the present invention in a state where a detection switch is pulled out, and FIG. 2 is a rear view in which a ball receiving portion and a mounting substrate constituting the winning device are disassembled. The perspective view seen from the side, FIG. 3 is the center longitudinal right side view explaining a use condition, FIG. 4 is the front view made into the cross section along the AA of FIG. Reference numeral 1 in the drawing denotes a main body portion of the winning device of the present invention, and reference numeral 2 denotes a detection switch assembled to the main body portion 1.

  As shown in FIG. 2, the main body portion 1 is composed of a ball receiving portion 3 and a mounting substrate 4, and the ball receiving portion 3 is opposed to both sides on the back side of the front-side decorative plate 5. The two side frame plates 6 and 6 are extended in parallel, and are formed so as to have a substantially U-shaped cross-sectional shape in the cross-sectional shape. In this way, an incoming ball passage 7 having a rear portion opened therein is formed. Then, inwardly extending ridges 8 and 8 are provided at the upper ends of the left and right side frame plates 6 and 6 to narrow the distance between them, and in parallel with the ridges 8 and 8, the interval is lowered. The protrusions 9 and 9 are raised, and a mounting receiving portion 10 having a groove shape is formed by forming these two upper and lower protrusions.

  The mounting receiving portion 10 is for receiving and fixing the leading edge when the detection switch 2 is mounted. Here, a groove 11 is formed on the back surface of the decorative plate 5 so as to extend the groove. A groove is formed in a U-shape across the front and left and right surfaces to form the mounting receiving portion 10.

On the other hand, the mounting substrate 4 is combined with the ball receiving portion 3 to close the intrusion ball passage 7 that is open at the rear to form a cylindrical passage that penetrates substantially vertically. 3, the rear ends of the left and right side frame plates 6 and 6 are brought into contact with each other, and screws 14 and 14 are screwed into screw receiving holes 13 and 13 provided in the side frame plates 6 and 6 through the through holes 12 and 12 from the back side. It is supposed to be united with.
The mounting substrate 4 is provided with a through hole having a horizontally long rectangle corresponding to the mounting receiving portion 10 located in the front, and is set as a mounting hole 15 through which the detection switch 2 is inserted.

  The mounting hole 15 is formed in a horizontally long rectangular shape that substantially matches the cross-sectional shape of the detection switch 2, and a guide base 16 for guiding the tip of the detection switch mounted along the lower edge portion on the back side. Further, a locking piece 18 having an inward claw 17 at the front end is extended from one edge of the guide stand to the rear, and the rear end of the detection switch to be mounted is latched, so that it can be pulled out arbitrarily. Is preventing.

In the figure, 19 is a lamp attached to the back surface of the mounting board 4 to illuminate the winning device, and 20 is a screw hole for fixing the mounting board 4 to the game board 21.
In addition to being used for illumination, the lamp 19 may be a lamp for display, for example, a lamp that is turned on when a hit ball passes through the entry ball passage 7, or may be a combination of both.

  The ball receiving portion 3 and the mounting substrate 4 constituting the main body portion 1 of the winning device are each formed by injection molding using a thermoplastic synthetic resin as a material. For this reason, in consideration of die cutting as shown in the figure, for example, the ball receiving portion 3 has a shape with the rear opened as described above, and the mounting substrate 4 has the locking piece 18 from the edge of the guide base. It is provided so as to protrude on the rear extension line of the mounting hole 15.

  When the ball receiving portion 3 and the mounting substrate 4 which are individually formed in this way are assembled together, the screws 14 and 14 are screwed into the screw receiving holes 13 and 13 so as to be integrally coupled, thereby the ingress ball passage. 7 is an upper and lower through hole, and the mounting hole 15 faces the back of the mounting receiving portion 10.

When the detection switch 2 is mounted, the tip edge is slid onto the upper surface of the guide base 16 to be inserted into the attachment hole 15, and is pushed down to slide the both edges of the tip onto the groove-shaped attachment receiving portion 10. However, when it is further inserted into the groove 11 and the rear end of the detection switch 2 reaches the claw 17 of the locking piece 18, the claw is hooked and the mounting operation is completed.
As shown in FIGS. 3 and 4, the ball detection hole 22 is connected to the incoming ball passage 7 of the ball receiving portion 3 as a result of the attachment of the detection switch 2, and the inner wall surface 22a of the ball detecting hole 22 is attached to the attachment receiving passage. The inner wall 7a of the incoming ball passage 7 entering the three grooves forming the portion 10 and more specifically, the inner wall substantially formed by the upper and lower ridges 8, 8, 9, 9 respectively. Retreating further outward from the wall surface forms an annular recess.

  By the way, the incoming ball passage 7 formed in the ball receiving portion 3 is formed so that the inner diameter thereof is a diameter through which the pachinko ball can pass, but the upper and lower portions projecting from the inner wall surface 7a and forming the mounting receiving portion 10 are formed. The two protrusions 8, 8 and 9, 9 are formed with an interval larger than the diameter of the pachinko sphere (approximately 11 mm) and smaller than the diameter of the sphere detection hole 22, respectively. The back surface and the front surface of the mounting substrate 4 are formed so as to be aligned with the distance between the left and right protrusions, and when the pachinko ball, that is, the incoming ball A passes through the region of the mounting receiving portion 10 formed by the protrusions, The incoming ball A is allowed to pass through without contacting the inner wall surface 22a of the ball detection hole 22 (see FIGS. 3 and 4).

  That is, the protrusions 8, 8 and 9, 9 form a portion raised from the inner peripheral surface 7a of the incoming ball passage 7, and the detection switch 2 is protected by the upper and lower portions.

Therefore, from the above structure, the hitting ball A enters the winning device of the present invention, which is mounted by being screwed through the screw hole 20 with the mounting substrate 4 facing from the front side of the mounting through hole 23 established in the game board 21. In this case, the ball A jumps into the incoming ball passage 7 penetrating up and down, but in reality, the ball A has the upper protrusions 8 and 8 corresponding to the opening 7b of the passage 7, the decorative plate 5, A space formed by the front surface of the mounting substrate 4 is entered.
The hit ball A that enters the space of the opening 7b, that is, the incoming ball A passes through the ball detection hole 22 of the detection switch 2 and is formed by the decorative plate 5 and the mounting substrate 4 in the same manner as the protrusions 9 and 9 below. Through the same space as the opening 7b is released from the jumping ball passage 7 to the gaming part of the game board. During this time, the passage of the jumping ball A is detected by the detection switch, and the electric signal is output. It will be converted and sent.

  When passing through this ball A, the inner wall surface 22a of this ball detection hole enters the inside of the mounting receiving portion 10 and passes through the upper and lower ridges 8,8. 9 and 9, the collision between the intrusion sphere A and the upper opening of the sphere detection hole 22 also comes into contact with the inner wall surface 22 a of the sphere detection hole 22. Thus, the detection switch is therefore used without being damaged or contaminated by collision or contact.

  Therefore, the detection switch 2 that has been used as described above is released from the mounting hole 15 by disengaging the locking piece 18 when the winning device is to be disposed of due to disposal of the game board or the like. It can be used for reuse by replacing the main body part prepared separately. Of course, the main body portion of the winning device prepared in this case may be the main body portion related to the same design, but it is mounted on a separately designed one and incorporated into a new winning device, and reused as a new one. It becomes possible to measure.

  In the illustrated embodiment, the upper and lower ridges 8 and 9 forming the mounting receiving portion 10 are formed as parallel ridges facing the left and right side frame plates 6 and 6, and the front side is the back side of the decorative plate 5. Furthermore, the rear wall side is used as the front surface of the mounting substrate 4 to make the inner wall surface shape of the incoming ball passage 7 at the upper and lower protrusions 8 and 9 into a rectangular tube shape. The strips 8, 8 and 9, 9 are each extended to the back of the decorative plate 5 on the front side, and the shape from above is formed into a U-shape, and is adjusted to the position of each of the projections 8, 8, 9, 9 A protrusion having a concave curved surface at the front edge portion is provided on the front surface of the mounting substrate 4 so that the overall shape is circular by combining these protrusions, that is, the inner wall surface 7b of the protrusion is circular. Needless to say.

 Also, in this case, the circular hollow portion formed, that is, the inner diameter is made larger than the diameter of the pachinko ball A in the same manner as in the case of the two protruding ridges 8, 8, 9, 9. Needless to say, the diameter of the ball detection hole 22 of the detection switch 2 supported by the portion 10 is smaller than the diameter.

The perspective view from the back side of the winning device which concerns on this invention in the state which extracted the detection switch. The perspective view seen from the back direction which decomposed | disassembled the ball receiving part and attachment board which comprise a prize-winning apparatus. The center longitudinal cross-section right view in use condition. It is the front view made into the cross section along the AA in FIG.
