The rolling passage formation member includes a spiral groove 40a for forming a rolling passage part 34, where the game ball B rolls and falls while performing rotary movement repeatedly, in a partial ball circulation passage (ball discharge passage 32) that includes a ball supply passage for supplying the game ball B to a ball shooting part and the ball discharge passage 32 for discharging the game ball B from a game area, and circulates the game ball B via the game area.

Description

  The present invention relates to a pachinko gaming machine, and in particular, a rolling passage portion in which a game ball rolls and falls while being repeatedly rotated is formed in a part of the ball circulation passage.

  Conventionally, in a pachinko gaming machine, when the launch handle is turned, a game ball supplied from the storage dish to the ball launcher is launched into the game area formed on the game board by the ball launcher. When there are a plurality of game balls in the storage tray, the plurality of game balls are continuously fired at intervals of about 0.6 seconds. A plurality of winning holes are provided in the gaming area, and when a game ball wins a winning hole, a plurality (several to ten or more) gaming balls can be obtained for each winning game ball.

  In the recent mainstream pachinko machines that have a start opening and an openable large winning opening as a winning opening in the game area, a big hit lottery is performed when a game ball wins a winning opening, and it was won in the big win lottery In this case, a big hit game is usually generated in which a closed winning prize opening is opened and closed over a plurality of rounds. Due to the occurrence of the big hit game, a plurality of game balls win the big prize opening in a short period of time, so that a large number (from several hundred to several hundreds) of game balls can be obtained.

  In a general pachinko machine, all acquired game balls are paid out to a storage tray. Therefore, when a big hit game occurs, the game balls in the storage tray overflow, so most of the paid out game balls are taken out from the storage tray and stored in a storage box (so-called dollar box) and stored as holding balls. Later, the ball can be used in a storage tray. Normally, when there is no ball, until a big hit game is generated, a plurality of (for example, 25) game balls are purchased by a ball purchase device arranged in parallel with a pachinko game machine and used in a storage tray. .

  In pachinko gaming facilities where multiple pachinko machines are installed on an island structure, generally, ball circulation is achieved by circulating game balls through the game area of each pachinko machine across each pachinko machine and island structure. A passage is provided. In this ball circulation passage, an island-side ball supply passage and an island-side ball discharge passage common to a plurality of pachinko machines are provided in the island structure, and game balls are stored in each pachinko machine from the island-side ball supply passage. A ball supply passage for supplying to the dish (that is, the ball launcher) and a ball discharge passage for discharging the game ball from the game area (out port or the like) to the island-side ball discharge passage are provided.

  On the other hand, a ball-enclosed pachinko game machine in which game balls are enclosed so that they cannot be taken out has been put into practical use. In this ball-enclosed pachinko machine, the number of game balls purchased, the number of shots, the number of acquisitions, etc. are managed by the computer. Therefore, a predetermined number (for example, about several hundred to several thousand) of game balls It can be configured to be able to play by being enclosed so as to be circulated in the gaming machine. The island-side sphere supply passage and the island-side sphere discharge passage of the island structure can be omitted.

  By the way, in conventional pachinko gaming facilities, usually, outside of the actual operation of the pachinko gaming machine, a large number of gaming balls are collected from the pachinko gaming machine through the island side ball discharge passage and cleaned by a dedicated cleaning device. To do. However, such cleaning of game balls is a very large-scale operation, and it is considered unreasonable to collect and clean a large number of game balls from a plurality of ball-enclosed pachinko machines. Therefore, the following technology has been developed in response to a request to clean the game balls circulating during the actual operation of the pachinko gaming machine.

  In the pachinko gaming machine of FIG. 1 (FIG. 1), a polishing member for cleaning the game ball is provided on the outer rail of the ball launch passage that guides the launched game ball to the game area. In the pachinko gaming machine of Patent Document 2 (FIG. 5), the right end portion of the game area is partitioned by a separate rail, and a ball polishing passage is formed by the rail and the outer rail, and polishing is performed on the outer rail of the ball polishing passage. A member is provided. In the case where the upstream end of the ball polishing passage is opened and closed by the opening / closing member and the game ball is cleaned, when the game ball is hit to the right with the opening / closing member opened, it is introduced into the ball polishing passage and cleaned by the polishing member. In the pachinko gaming machine (FIG. 1) of Patent Document 3, a part of the ball discharge passage is formed by an inclined linear polishing rod, and a plurality of cuts are formed in the polishing rod, and a game is played at the step portions of the plurality of cuts. The sphere is cleaned.

  In the pachinko gaming machine (FIG. 1, FIG. 8) of Patent Document 4, a part of a ball supply passage for supplying a game ball to a ball launcher is formed in a U-shaped passage, and includes a sprocket and an electric motor. Thus, the game ball is conveyed upward in the rising path of the U-shaped path, and the cleaning member is disposed in the rising path so as to come into contact with the game ball. In the pachinko gaming facility of Patent Document 5 (FIGS. 1 and 12), the island structure is provided with a rising passage from the island-side ball discharge passage side to the island-side ball supply passage side, and the same ball transport as in Patent Document 4 By the mechanism, the game ball is conveyed upward in the ascending passage, and an abrasive tape is disposed in the ascending passage so as to come into contact with the game ball.

  The cleaning techniques of Patent Documents 4 and 5 both clean a game ball using the driving force of a ball transport mechanism. In the pachinko gaming machine of Patent Document 6 (see FIGS. 5 and 7), an elongated brush member is disposed along a straight passage portion of a ball supply passage for supplying game balls to a ball launching portion, and the brush member is an electric motor. Is driven to rotate and cleans the game ball.

  As shown in FIGS. 6 to 12, in this pachinko gaming machine 1, a rolling passage portion 34 is formed in a part of the ball circulation passage 30 so that the game ball B rolls and falls while being repeatedly rotated. A rolling passage forming member 40 having a spiral groove 40a is provided. The rolling passage portion 34 is provided in the ball discharge passage 32 of the ball circulation passage 30.

The rolling passage forming member 40 and the like will be described in detail.
In the sphere discharge passage 32, a sphere assembly passage forming member 35 that forms a T-shaped sphere assembly passage portion 33 is provided at an upstream portion thereof, and a spiral rolling passage portion is provided downstream of the sphere assembly passage portion 33. A rolling passage forming member 40 capable of forming 34 is provided.

  A rolling passage forming member 40 is disposed near the lower part of the ball collecting passage forming member 35, and a small stock portion 21 is disposed near the lower part of the rolling passage forming member 40. A plurality of game balls B discharged from the out-port 11b and the winning opening of the game area 11 are gathered by the ball gathering passage 33, sequentially discharged from the lower end thereof, and transferred to the rolling passage 34, and the rolling The passage portion 34 is dropped while being repeatedly rotated, discharged from the lower end thereof, and collected in the small stock portion 21.

  The small stock portion 21 is formed in a horizontally long box shape that opens upward, and a rolling passage forming member 40 is disposed above the right portion of the small stock portion 21. The bottom surface of the small stock portion 21 is inclined downward toward the left front, and the plurality of game balls B collected from the rolling passage forming member 40 move to the left front portion of the small stock portion 21 and from there It is supplied to the first transport mechanism 28.

  In the rolling passage forming member 40, the bottom surface 40a1 of the spiral groove 40a forms a rolling surface 40a1 on which the game ball B rotates, and the lower center side of the spiral groove 40a (rolling surface 40a1) (of the spiral groove 40a). There is a drop hole 40b at the downstream end).

  For example, the spiral groove 40a is formed to go from the outer peripheral end (upstream end) about 2.5 to 3 and reach the center (downstream end), and the gradient is about 5 degrees. From the downstream end of the spherical collecting passage portion 33, it is discharged rearward (horizontal direction) at an appropriate speed, and is transferred to the upper end of the spiral groove 40a and the upstream end of the left end. For about 5 seconds), dropping and passing several times in the clockwise direction (for example, 2.5 to 3 rotations) in plan view, and finally falling to the small stock portion 21 from the drop hole 40b. .

  The bottom surface 40a1 of the spiral groove 40a has a function of cleaning the game ball B by contact with the game ball B. The rolling passage forming member 40 is a sheet-like or film-like member that is replaceably mounted on a synthetic resin-made main body member 41 having a spiral groove portion 41a having substantially the same shape as the spiral groove 40a, and the entire bottom surface of the spiral groove portion 41a. The bottom surface 40a1 of the spiral groove 40a is formed by this polishing member 42, and a cleaning function is obtained.

  The polishing member 42 is made of a material that imparts relatively high friction to the game ball B, and polishes the game ball B so as to remove dirt from the game ball B. The polishing member 42 is formed in a spiral shape, and is adhered to the bottom surface of the spiral groove portion 41 a of the main body member 41 with a tape material or the like in close contact.

The rolling passage forming member 40 is fixed in a stable state with its axis being vertical.

  Note that the size and shape of the rolling passage forming member 40 (the inclination of the rolling surface 40a, etc.), the speed at which the game ball B is transferred to the rolling passage portion 34, the polishing member 42 and the game ball B In consideration of friction acting between them, several (for example, 5 to 6) game balls B stay in the rolling passage portion 34 at the same time and can smoothly roll without colliding as much as possible. And it sets suitably so that a desired cleaning function may be acquired.

The pachinko gaming machine 1 (ball circulation device 6) has the following effects.
Since the rolling passage forming member 40 having the spiral groove 40a that forms the rolling passage portion 34 in which the game ball B rolls and falls while rotating rotationally repeatedly is formed in a part of the ball circulation passage 30, the pachinko During actual operation of the gaming machine 1, the game ball B circulating in the ball circulation passage 30 rolls on the rolling passage formation member 40 and falls while rotating, so that the game ball B can be cleaned. .

  The individual game balls B can be reliably cleaned by the spiral grooves 40a of the rolling passage forming member 40 because the individual game balls B are guided in an orderly manner so as to drop while rotating. That is, to remove the dirt of the game ball B as much as possible and play normally using the game ball B, that is, normal launch of the game ball B, collision with the obstacle nail (bounce back), to the winning opening It is possible to maintain winnings etc.

  Since the driving energy is not required separately using the potential energy of the game ball B for cleaning, the rolling passage forming member 40 is further dropped while rotating the game ball B repeatedly. Therefore, the structure of the rolling passage forming member 40 can be simplified and made compact. Therefore, the production cost and running cost of the rolling passage forming member 40 can be reduced, the installation space can be easily secured, and the game ball B is launched into the game area 11 (that is, a game). Can be prevented from being adversely affected, and the appearance can be prevented from deteriorating.

  Since the bottom surface 40a1 of the spiral groove 40a has a function of cleaning the game ball B by contact with the game ball B, the game ball B rolls on the bottom surface 40a1 of the spiral groove 40a and falls while rotating, The game ball B can be reliably cleaned.

  Since the bottom surface 40a1 of the spiral groove 40a is formed by the sheet-like or film-like polishing member 42 that is replaceably mounted on the rolling passage forming member 40, the base of the rolling passage forming member 40, that is, the main body member 41 The structure can be simplified, and when the cleaning function deteriorates due to long-term use of the polishing member 42, the cleaning function can be easily improved by replacing the polishing member 42 with a new one.

  Since the rolling passage portion 34 is provided in the ball discharge passage 32, the game ball B is discharged from the game region 11 even when the game ball B is contaminated by being launched into the game region 11 (game board 10). After that, the game ball B can be cleaned immediately.

  Since the pachinko gaming machine 1 is a ball-sealed pachinko gaming machine 1 in which a game ball B is enclosed so as not to be taken out, a general pachinko gaming machine in which a plurality of pachinko gaming machines are installed on an island structure is described. In contrast, it is unreasonable to collect and wash a large number of game balls B from a plurality of ball-enclosed pachinko gaming machines 1 in a lump.

  Therefore, although the pachinko gaming machine 1 is provided with the cleaning device 2 individually, it is physically and regularly used to clean the game ball B when the pachinko gaming machine 1 is actually operated using the cleaning device 2. Therefore, by providing the rolling passage forming member 40 that forms the rolling passage portion 34 in a part of the ball circulation passage 30, the rolling passage forming member 40 allows the game ball to be used during actual operation of the pachinko gaming machine 1. B can be cleaned.

  In the rolling passage forming member 40, the polishing member 42 is omitted, and a polishing portion corresponding to the polishing member 42 and having relatively high durability is integrally formed on the bottom surface of the spiral groove portion 41 a of the main body member 41. May be. The number of parts of the rolling passage forming member 40 is reduced, which is advantageous in manufacturing cost.
