In the same manner as described above, the special prize starting means 16 is provided with the locked portion in the special winning means 16 and the engaging claw in the special symbol starting means 15. It is good also as a structure which enables 15 single drawers.

  Further, as shown in FIGS. 2 and 4, the special winning means 16 includes normal winning means 18 at both the left and right sides thereof. As shown in FIG. 9 and FIG. 12, the normal winning means 18 of the big winning means 16 guides the normal winning opening 80 in which the game balls are opened upward so that the winning can be won, and the gaming balls won in the normal winning opening 80. Guide path 81 to be guided, a downward guide path 82 for guiding the game ball from the guide path 81 downward, and a winning detection for a normal prize placed on the downstream side of the downward guide path 82 for detecting the passage of the game ball A sensor 83 (for example, a proximity sensor).

  As described above, in the pachinko machine according to the present embodiment, the game board 7 having the game area 12 where the game balls flow down, the glass plate 5b arranged to face the game area 12 at a predetermined interval, and the game A special symbol starting means 15 and a large winning means 16 which are arranged in the game area 12 so that a ball can be won, a second special symbol winning detection sensor 62 for detecting a gaming ball won by the special symbol starting means 15, and a large A prize winning detection sensor 56 capable of detecting a game ball won in the prize winning means 16 and having a function of detecting magnetism, and a special symbol starting means 15 in the detection range by the prize winning detection sensor 56 for big prize. The big prize winning detection sensor 56 is arranged so that the winning means 16 is located.

  That is, since the winning detection switch with magnetic detection function (large winning winning detection sensor 56) is provided, it is not necessary to arrange a dedicated magnetic sensor separately from the winning detection switch, and the number of parts can be reduced. An installation space can be eliminated. Further, since the special prize starting detection means 15 and the special prize winning means 16 are arranged so that the special symbol starting means 15 and the special prize winning means 16 are located in the magnetic detection range by the special prize winning detection sensor 56, a prize with a magnetic detection function is provided. A detection switch (a winning prize detection sensor 56) can cover both the special symbol starting means 15 and the winning prize means 16, and it is not necessary to replace all winning detection switches with a winning detection switch with a magnetic detection function. A winning detection switch with a magnetic detection function can be used effectively.

  The distance between the second special symbol winning detection sensor 62 and the special winning prize detection sensor 56 is smaller than the distance between the special symbol starting means 15 and the special winning means 16 winning opening. In other words, the second special symbol winning detection sensor 62 and the big winning prize detection sensor 56 are arranged closer to the distance between the special symbol starting means 15 and the big winning means 16. The second special symbol winning detection sensor 62 is also located in the magnetic detection range of the special winning winning prize detection sensor 56, and it is possible to detect an illegal act due to magnetism aiming at the second special symbol winning detection sensor 62. .

  The special symbol starting means 15 and the big winning means 16 are separate parts, and either the special symbol starting means 15 or the big winning means 16 has both the second special symbol winning detection sensor 62 and the big winning prize detection sensor 56. Therefore, the second special symbol winning detection sensor 62 and the big prize winning detection sensor 56 can be disposed close to each other in one winning means, and the second special symbol winning detection sensor 62 and the big prize winning are provided. It is possible to more reliably detect an illegal act due to magnetism aimed at the prize winning detection sensor 56. Further, since the other winning means is not provided with the winning detection switch, the size can be reduced.

  Since the special symbol starting means 15 and the solenoid 41 and the opening / closing driving means 55 (electrical parts) related to the special winning means 16 are arranged outside the detection range by the winning prize winning detection sensor 56, the solenoid 41 and the opening / closing driving means 55 are provided. It is possible to reduce the false detection caused by. For example, the special symbol starting means 15 includes a blade member 33 (opening / closing member) for opening and closing the winning opening and a solenoid 41 for driving the blade member 33. The special winning means 16 includes an opening / closing plate 52 for opening / closing the special winning opening 51 and an opening / closing driving means 55 such as a solenoid for driving the opening / closing plate 52. Since the solenoid 41 and the opening / closing drive means 55 are disposed outside the detection range, it is possible to reduce the detection of the magnetism by the solenoid 41 and the opening / closing drive means 55 by the big prize winning detection sensor 56, thereby reducing erroneous detection. it can.

  In addition, as shown in FIG. 2, the out ball opening 14 is included in the detection range by the big prize winning detection sensor 56, so that when the fraudster approaches the out ball opening 14, the magnetism is detected, It is also possible to detect fraudulent acts aimed at the out ball port 14. Specifically, for example, a cheating person brings the magnet close to the out-ball mouth 14 and clogs, for example, about 10 game balls in the out-ball mouth 14, and then the game ball is clogged even if the magnet is released. It reduces the illegal act that game balls falling from above accumulate from the out ball opening 14 to the special symbol starting means 15 (starting opening) and reach the special symbol starting means 15 (starting opening) for winning. can do.

  In addition, a special symbol starting means 15 and a big winning means 16 for guiding the winning game balls to the back side of the gaming board 7 are provided on the gaming board 7 having the gaming area 12 where the gaming balls flow down, adjacent to each other vertically, The second special symbol winning detection sensor 62 for detecting the game ball won in the special symbol starting means 15 is mounted on the mounted portion 60 formed in the range of the large winning means 16 in the rear view of the large winning means 16. . Accordingly, since the second special symbol winning detection sensor 62 of the special symbol starting means 15 is disposed on the large winning means 16 side, the storage portion of the second special symbol winning detection sensor 62 and the storage portion follow. The discharge passage and the like can be removed from the special symbol starting means 15, and the special symbol starting means 15 can be reduced in size, and the special symbol starting means 15 can be made closer to the big winning means 16. In addition, the special winning means 16 is formed with the mounted portion 60 to which the second special symbol winning detection sensor 62 is attached within the rear view range, so that the special winning means 16 itself may be bulky. Absent. Therefore, the total height (total height) of the special symbol starting means 15 and the special winning means 16 can be reduced. As a result, the game area 12 of the game board 7 and the arrangement area of the movable effect means (for example, a movable accessory) can be expanded.

  Moreover, the to-be-attached part 60 is formed in the location which the special symbol starting means 15 respond | corresponds to the upper side location of the big winning means 16 within the said range. That is, since the second special symbol winning detection sensor 62 is disposed in the large winning means 16 at a location close to the special symbol starting means 15, the second special symbol winning is provided downstream of the special symbol starting means 15. Winning can be detected at almost the same timing as when the detection sensor 62 is provided, and the player does not feel a delay in detecting the winning to the special symbol starting means 15. On the other hand, when the second special symbol winning detection sensor 62 is provided on the lower side of the large winning means 16, the winning detection is performed at a timing later than the above-described configuration, and the winning detection to the special symbol starting means 15 is detected. It becomes easy for the player to feel the delay of the game, and there is a risk that the game may be distrusted due to the uncomfortable feeling of winning detection.

  Further, since the mounted portion 60 is exposed on the back side of the special winning means 16 so that the second special symbol winning detection sensor 62 can be attached and detached, for example, it is provided on the special winning means 16 side. If the second special symbol winning detection sensor 62 fails or the like, the second special symbol winning detection sensor 62 can be replaced from the back side of the big winning means 16, and the large winning means 16 can be disassembled or the game board 7 can be disassembled. It is not necessary to replace the second special symbol winning detection sensor 62 by removing it.

  The special winning means 16 includes an attached portion 59 to which a special winning prize detection sensor 56 for detecting a game ball that has entered the winning case 54 is attached, and a special prize winning attached to the attached portion 59 is provided. A second special symbol winning detection sensor 62 mounted on the mounted portion 60 is disposed at a position where the detection sensor 56 is removed. That is, since the second special symbol winning detection sensor 62 in the state of being attached to the mounted portion 60 is located at a position where the winning winning prize detection sensor 56 is removed, the removal of the special winning prize winning detection sensor 56 is removed. Can be suppressed. In other words, unless the second special symbol winning detection sensor 62 is removed, the special winning prize detection sensor 56 cannot be removed, and the illegal winning prize detection sensor 56 is excellent in fraud reduction.

  The special symbol starting means 15 is formed on the front side of the game board 7 so that a game ball can be won. The special symbol start means 15 communicates with the lower special start opening 32 and sends the game ball to the back side of the game board 7. The second special symbol winning detection sensor 62 includes a lower depth passage 30 and a downward guide passage 38 that gently and downwardly incline guide, and a downward discharge port 38b formed on the downstream side of the downward guide passage 38. Is provided with a through-hole 62a through which a game ball can pass, and detects the passage of the game ball into the through-hole 62a, and is penetrated by the second special symbol winning detection sensor 62 mounted on the mounted portion 60. The hole 62a is located immediately below the discharge port 38b, and allows a game ball from the discharge port 38b to enter. Accordingly, the lower depth passage 30 and the downward guide passage 38 of the special symbol starter 15 are inclined gently downward, so that the lower part of the bottom surface where the lower depth passage 30 and the downward guide passage 38 of the special symbol starter 15 exist is located below. The protruding amount can be reduced, and the special symbol starting means 15 can be arranged in contact with or close to the big winning means 16 in the front view of the game board 7. Further, since the through hole 62a of the second special symbol winning detection sensor 62 mounted on the mounted portion 60 communicates directly under the discharge port 38b, the large winning means 16 itself does not become bulky. Therefore, the overall height of the special symbol starting means 15 and the special winning means 16 can be made smaller. As a result, the game area 12 of the game board 7 and the arrangement area of the movable effect means can be further expanded.

  For example, the lower depth passage 30 and the downward guide passage 38 may be inclined more gently than the downward inclination of the lower special start port 32 (guide rib 32a). Note that the gradient of the lower depth passage 30 and the downward guide passage 38 is, for example, two vertical distances (for example, a distance equal to or less than 1/4 of the diameter of the game ball) versus horizontal distances (for example, one or more of the game balls). The ratio of the following distance) is mentioned. In this case, the bottom face of the special symbol starting means 15 can be brought into contact with or close to the top face of the big winning means 16 (for example, 1 or 2 mm). The arrangement can be close to a minute gap (for example, about 1 mm or 2 mm).

  The special symbol starting means 15 includes a first special symbol starting means 15a and a second special symbol starting means 15b which are arranged adjacent to each other in the vertical direction, and the second special symbol winning detection sensor 62 includes: The game balls won in the second special symbol starting means 15b are detected, and the discharge passages (first to third discharge passages 71 to 71) of the first special symbol starting means 15a, the second special symbol starting means 15b and the big winning means 16 are detected. 73) are formed side by side in the rear view of the big winning means 16, so that the depth length of the big winning means 16 is longer than the configuration in which the first to third discharge passages 71 to 73 are arranged in the depth direction of the big winning means 16. The length can be shortened, and space saving in the depth direction can be achieved.

  Further, the first special symbol starting means 15a is composed of an upper depth passage 29, a communication rear side passage 35 and a hanging passage 36, and the game ball from the lateral opening 39 of the hanging passage 36 is a big winning means. Since it is received by the 16 horizontal downward passages 71a and discharged in the back direction or the downward direction, it has a special pattern as compared with a configuration including a lateral refraction post-hanging passage that refracts laterally and hangs down on the back side of the communication back side passage 35. The lateral width of the starting means 15 can be reduced. Specifically, in the configuration including the lateral refraction post-hanging passage, the horizontal width of the special symbol starting means 15 is increased by the amount of the horizontal refraction post-hanging passage. Since it is a guide passage that hangs down later and does not include the above-described lateral refraction suspending passage, the lateral width of the special symbol starting means 15 can be reduced. Further, since the game balls from the first special symbol starting means 15a are received by the laterally descending passage 71a having a height lower than that of the top surface of the big winning means 16, it is not necessary to provide a passage portion protruding from the upper surface of the big winning means 16. The increase in the height of the big winning means 16 can be reduced.

  Further, the first special symbol winning detection sensor 37 and the second special symbol winning detection sensor 62 are positioned vertically with their through holes 37a, 62a facing downwards, and each through hole 37a in plan view. 62a are disposed in the opposite direction in the front-rear direction so that they do not overlap, so that two paths of the first special symbol starting means 15a and the second special symbol starting means 15b can be formed with a minimum depth. it can.

  Further, since the second special symbol winning detection sensor 62 is disposed with a gap D below the hanging passage 36 of the first special symbol starting means 15a, the hanging passage 36 of the first special symbol starting means 15a. It is possible to prevent the impact of the game ball flowing down the bottom portion of the hanging passage 36 from being transmitted to the second special symbol winning detection sensor 62, and to reduce the malfunction of the second special symbol winning detection sensor 62. The failure of the second special symbol winning detection sensor 62 due to the continuous impact of the game ball can be reduced.

  Further, the upper surface portion of the second special symbol winning detection sensor 62 in the mounting direction front end side is covered with the covering portion 66, so that, for example, an unauthorized person moves up the second special symbol winning detection sensor 62 in the mounting direction front end side. Even if it is moved in the direction to be removed, the removal in the upward direction is restricted, and fraud can be reduced.

  Further, as shown in FIG. 7, the stepped portion (locked portion 75b) at the lower portion of the front decorative base plate 28 of the special symbol starting means 15 is a rounded corner portion with roundness.
