Description

  The present invention relates to a winning device including a front door for opening and closing a winning opening of a gaming machine.

  In a game area of a gaming machine such as a pachinko machine, a plurality of winning devices including a front door for opening and closing a winning opening are installed. A large winning device, which is one of the winning devices, has a rectangular front door that opens and closes a horizontally long rectangular winning opening. The front door is provided with a rotation shaft at the lower end, and the upper end is rotated upward and forward (player side) to open and close the winning opening. When the upper end of the front door is tilted forward, the front door receives a ball that flows down the game area on the back side and wins a winning opening.

  In the center of the game area, a center accessory having a variable symbol display device is provided, and a start winning opening is arranged below the center combination. When the symbols change on the condition that the ball wins the start winning opening and the symbols when stopped are in a predetermined combination, the front door of the winning device is opened as a so-called big hit. When the ball counting sensor provided in the winning opening detects the passage of a predetermined number of balls, or when a predetermined time has elapsed, the front door is rotated upward and the winning opening is closed.

  In the conventional winning device, for example, as described in Patent Document 1, even when the ball counting sensor detects a predetermined number of balls, the ball on the back surface of the front door or the ball counting still A ball present in the winning opening not detected by the sensor is taken into the winning opening when the front door is closed. As a result, more than a predetermined number of prize balls are paid out, resulting in a disadvantage to the hall side.

Conventionally, as shown in FIG. 7 of Patent Document 1, a bottom plate for guiding the ball to the ball counting sensor is disposed in the case of the winning device so as to be inclined downward toward the ball counting sensor. It had been. Therefore, the prize-winning device is extended rearward as much as the bottom plate is provided, and the overall height is increased by the downward slope. However, in recent years, as the game contents become more complex, the display form of the variable symbol display device has become more complex, and the proportion of the center role in the game area has increased. Such an increase in the size of the center accessory has a narrow space for arranging various decorative members, and the demand for downsizing in the vertical direction is also increasing particularly in the winning device.
JP 2000-037518 A

  In view of the above-described conventional problems, an object of the present invention is to provide a winning device for a gaming machine in which balls are not paid out more than a predetermined number and can be downsized.

A winning device for a gaming machine according to the present invention made to solve the above-described problems, a vertical guide plate is disposed in front of an opening provided with a winning opening with a gap through which a ball can pass,
In the opening, after arranging the front door that opens the prize opening when the upper end is rotated forward from upward,
The back surface of the front door is characterized in that a guide portion is formed to guide the ball toward the winning opening while holding the ball between the guide plate when the front door is open. is there.

  In the above-described invention, a plate-like portion for guiding the sphere backward is provided on the back surface of the front door, and a guide portion having an arc surface whose radius of curvature gradually decreases toward the plate-like portion is formed. . In addition, a ball counting sensor is disposed as an award opening in the opening adjacent to the plate-like portion, and a plate-like portion is formed at one end on the back side of the front door.

  In the invention according to claim 1, since the guide portion for ball guidance can be positioned in front of the opening portion, it is no longer necessary to provide a bottom plate that is inclined in the lateral direction, which is conventionally provided in the winning opening of the winning device. Thus, the width and the overall height of the winning device can be reduced.

  In the invention according to claim 2, since the guide part is formed of a curved surface, when the front door is closed when the ball counting sensor counts a predetermined number of balls, the ball on the front door It falls down without entering. Therefore, no extra ball is won. Further, since the front door formed of a curved surface has a thickness, it is superior in strength when compared with a conventional plate-shaped front door.

  According to the third aspect of the present invention, there can be no undetected sphere in the opening due to the structure.

  In the invention according to claim 4, since the ball flows into the upper part of the plate from only one side, the ball can be smoothly flowed into the winning opening without causing the ball to be blocked at the winning opening.

Embodiments of the present invention will be described below with reference to the drawings.
1 to 3 are views showing a winning device of the present invention, wherein 1 is a front door mounting member, 2 is a main body case, 3 is a front door, and 4 is a guide plate member. The front door mounting member 1 is formed with an opening 11 having a horizontally long and substantially rectangular shape, and the front door 3 for opening and closing the opening 11 is pivotally attached to the left and right support shafts 31. .

  Adjacent to the front door 3, a ball counting sensor 5 that counts the passage of the ball is disposed on the front door mounting member 1 as a winning opening. In this embodiment, the ball counting sensor 5 is disposed at one end of the opening 11. A front door opening / closing lever 6 is disposed in the main body case 2, and a front door opening / closing solenoid 7 is attached to the rear of the main body case 2 together with a support member 8 that also serves as a heat sink. .

  The guide plate member 4 has a U-shape in plan view, and a guide plate 42 is provided perpendicularly to the left and right support plates 41. As shown in FIGS. It is arrange | positioned in parallel with the wide direction of the opening part 11, and has covered the opening part 11 front. The front surface of the front door mounting member 1 and the back surface of the guide plate 42 are separated by a gap through which one sphere can pass.

Details of the front door 3 will be described with reference to FIGS.
The front door 3 is pivoted about a lower support shaft 31 and closes the opening 11 when the upper end is upward, and opens the opening 11 when the upper end is forward facing a player. A stopper 43 is provided on the inside of the left and right support plates 41, and these abut against the front door 3, thereby restricting the maximum opening position of the front door 3. The front surface 32 of the front door 3 is formed flat so that it does not protrude from the front surface 32 of the front door mounting member 1 when the front door 3 closes the opening 11 (FIG. 6).

  A substantially triangular prism-shaped guide portion 33 is formed on the back surface of the front door 3 so as to extend laterally, and a ball-shaped winning plate portion 34 is provided at one end of the back surface. The guide portion 33 has an arc surface 35, and when the front door 3 is tilted forward, the arc surface 35 can hold the sphere between the guide plate 42. The circular arc surface 35 is formed so that the radius of curvature gradually decreases toward the plate-like portion 34, and the center of the sandwiched sphere is hung from the left to the right in FIG. The ball is shaped to sink gradually. Therefore, the ball on the guide part 33 can slowly flow down in the direction of the plate-like part 34. Also, the ball is formed so as to flow down gradually between the guide portion 33 and the plate-like portion 34. Therefore, it is possible to smoothly flow down between the guide portion 33 and the plate-like portion 34.

  Adjacent to the plate-like portion 34, the ball counting sensor 5 is disposed in the opening 11 in the vertical direction so as to be inclined rearward so that the balls do not stay inside the ball counting sensor 5. The plate-like portion 34 is formed on a steep slope toward the ball counting sensor 5 in order to shorten the time that the ball is on. Therefore, even when the ball counting sensor 5 counts a predetermined number of balls and the front door 3 is closed, the balls on the plate-like portion 34 are not taken in as extra winning balls.

The opening / closing structure of the front door will be described with reference to FIGS.
In a normal gaming state, the plunger 71 of the solenoid 7 protrudes due to the elastic force of the spring 72, and thus presses the branch portion 61 of the front door opening / closing lever 6. By this pressing, the front door opening / closing lever 6 rotates about the support shaft 62 and the engaging portion 63 presses the lower end portion 36 of the front door 3, so that the upper end of the front door 3 is positioned upward and the opening portion 11. Is closed (FIGS. 7 and 8).

  When the game state is a big hit, the plunger 71 is attracted by the energization of the solenoid 7, so that the pressing of the branch portion 61 is released. By this release, the front door opening / closing lever 6 is rotated by the weight of the balance 64 and the plunger 71 excited by energization attracting the metal portion provided at the tip of the branch portion 61, and the engaging portion 63 is lifted. Since the rotation projection 37 of the front door 3 is pressed, the weight of the front door 3 itself is also helped to tilt forward (FIGS. 9 and 10).

  In the winning device configured as described above, the front door 3 is opened when a big hit occurs. The ball jumping into the guide member 4 moves slowly in the direction of the plate-like portion 34 while being sandwiched between the guide portion 33 and the guide plate 42. The ball on the plate-like portion 34 immediately passes through the ball counting sensor 5 and wins.

  As soon as the ball counting sensor 5 counts a predetermined number of balls, the front door 3 is closed by energization of the solenoid 7. When the front door 3 is closed, the circular arc surface 35 is a curved surface with the support shaft 31 as the center, so that the ball riding on the guide portion 33 does not receive resistance from the guide portion 33 and is not guided backward. The ball formed between the guide portion 33 and the guide plate 42 falls downward from a gap that allows passage of a sphere. Therefore, no more than a predetermined number of balls are won after the completion of counting. Further, since the arcuate surface 35 is formed in the guide portion 33 and there is almost no resistance of the ball applied when the front door 3 is closed, the solenoid can be made smaller than before.

  The plate-like portion 34 may be installed at the center of the front door 3 or the plate-like portion 34 may be installed at both ends of the front door 3, respectively. It is desirable to install it at one end of the door because it is less likely to cause ball clogging.
