Description

  The present invention relates to a gaming machine in which a detecting means for detecting a game ball can be attached to and detached from a winning device in a gaming area on the front surface of a gaming board when performing a type test of the gaming machine.

  Normally, when a new type of gaming machine is developed, an inspection (type test) of whether or not the gaming machine meets a predetermined operational standard is performed at the Hodo Association (Secure Electronic Communication Technology Association) If it passes, sales to amusement stores are possible. The type test includes a real fire test for measuring a winning probability of a game ball launched into a game area to a winning device (for example, a starting winning device). Specifically, this real fire test is performed as follows. For example, when a game ball detection sensor for detecting a winning game ball is provided in the winning device, the winning probability of the game ball to the winning device is measured based on the number of times an electric signal is output from the game ball detection sensor. In this way, it is possible to determine whether or not the gaming machine satisfies the operation standard based on the measured winning probability. However, some winning devices are not provided with a game ball detection sensor. In this case, a test game ball detection sensor is attached to the winning device, and the winning probability of the game ball to the winning device is measured in this state.

  By the way, when the gaming machine is a type of gaming machine (so-called normal machine) that mechanically opens and closes the opening / closing members of a plurality of normal winning devices based on winning of a game ball to the winning device, A game ball detection sensor for paying out a prize ball is provided only at a certain winning prize opening. On the other hand, the above-mentioned game ball detection sensor is provided in a prize opening at the lower part of the prize winning device, that is, a winning mouth that triggers opening / closing of the normal winning device or a lose prize winning port that does not trigger opening / closing of the normal winning device. Not provided. Therefore, if the gaming machine is a normal machine, when performing a real fire test, a gaming ball detection sensor is attached from the back side of the gaming board to the winning hole at the bottom of the winning device, and the gaming ball to each winning hole is It is necessary to inspect the winning rate of A1. However, in a normal machine, since an interlocking mechanism that interlocks the opening and closing members is provided so as to surround the winning device, the component arrangement density on the back side of the game board is very high, and a test game ball detection sensor is attached. The place is narrow. Therefore, even if the game ball detection sensor is attached from the back side of the game board as described above, there is a problem that workability is very poor. Moreover, since it is necessary to remove the game ball detection sensor after the end of the real fire test, not only the workability is poor, but also the holder holding the game ball detection sensor may be damaged.

Therefore, the winning device is composed of a base plate fixed to the game board and a holding means capable of holding the game ball detection sensor, and the holding means holding the game ball detection sensor is connected to the base board from the front side of the game board. On the other hand, a technique for facilitating attachment / detachment of the game ball detection sensor by attaching / detaching the sensor has been proposed (for example, see Patent Document 1).
Japanese Patent Laid-Open No. 11-19280 (Claims 1, [0037] to [0043], FIGS. 11 to 13 etc.)

  However, since the prize-winning device provided in the ordinary machine has a plurality of prize-winning ports, it is necessary to attach and detach the game ball detection sensor for each prize-winning port when performing a real fire test. Therefore, even if the game ball detection sensor is attached / detached from the front side of the game board as in the prior art described in Patent Document 1, it is necessary to attach / detach the game ball detection sensor one by one, thereby improving workability. I can't. Therefore, a technique for fundamentally solving the above problems is required.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a gaming machine in which a plurality of detecting means can be efficiently attached to and detached from a winning device.

  In order to solve the above-mentioned problems, the invention according to claim 1 is a gaming machine including a winning device in a game area on the front side of a game board, wherein the winning device is an apparatus main body attached to the gaming area. A winning space that is formed in the apparatus body and into which game balls can flow, a plurality of winning holes that are positioned below the winning space and into which the gaming balls that have flowed into the winning space can win, and the winning space And a distribution unit that distributes the game balls that have flowed into the winning space to any of the plurality of winning ports, and each of the plurality of winning ports that detects the winning game balls that are won in the winning ports. A plurality of detection means holding portions capable of holding the detection means; and a front cover member attached to the front side of the apparatus main body, the plurality of detection means holding portions being connected to the detection means from the front side of the apparatus main body. Wearable front side It has a mouth part and a back side opening part to which the detection means can be mounted from the back side of the apparatus main body, and the front cover member covers the front side opening parts of the plurality of detection means holding parts. The gist of the gaming machine is characterized in that it is detachably attached to the apparatus main body.

  Therefore, according to the first aspect of the present invention, the detection means can be attached to and detached from the detection means holding portion not only from the back surface side of the device main body which is a narrow space but also from the front surface side of the device main body which is not a narrow space. Workability when attaching and detaching is improved. In addition, by attaching the detection means to the plurality of detection means holding portions and then attaching the front cover member, the detection means are fixed simultaneously, so that the plurality of detection means can be efficiently attached to and detached from the winning device. Can do.

  In addition, the material which forms a front side cover member is not specifically limited, A synthetic resin, a metal, etc. can be used. In addition, as a method of detachably attaching the front cover member to the apparatus main body, a locking claw provided on one of the front cover member and the apparatus main body is engaged with a locking hole provided on the other of the front cover member and the apparatus main body. And fixing the front cover member to the main body of the apparatus. However, from the viewpoint of not only easy attachment but also easy removal, the front cover member is preferably screwed to the apparatus main body.

  According to a second aspect of the present invention, in the first aspect, the detection means has a substantially rectangular flat plate shape, and is inclined with respect to the front end surface of the detection means at one corner of the front end portion of the detection means. And a back surface of the front cover member is provided with a misassembly prevention protrusion that abuts against the taper surface when the front cover member is attached to the apparatus main body. To do.

  By the way, even if the detection means having a shape different from that of the regular product is mounted on the detection means holding portion, the operator may not notice the erroneous assembly of the detection means. Moreover, even if the detection means is mounted upside down when the detection means is a genuine product, the operator may not notice the incorrect assembly. Moreover, since the winning device of the present invention has a plurality of detection means holding portions, the risk of erroneous assembly is high.

  Therefore, in the invention described in claim 2, a misassembly prevention protrusion is provided on the back surface of the front cover member. As a result, when a detecting means having a shape different from that of a regular product is mounted, or when a normal detecting means is mounted upside down, the front cover is covered with the wrong assembly preventing projection and the detecting means. The member cannot be attached to the apparatus main body. Thus, the operator is likely to notice incorrect assembly of the detection means.

  Furthermore, when the front cover member is attached to the apparatus main body, the misassembly prevention protrusion comes into contact with the taper surface of the detection means, so that the detection means is not only the detection means holding part but also the misassembly prevention protrusion. Retained. As a result, the fixing strength of the detection means is improved, and rattling of the detection means is suppressed. Further, the strength of the front cover member can be improved by providing the misassembly prevention protrusion.

  Here, as a method of bringing the misassembly prevention protrusions into contact with the tapered surface, the misassembly prevention protrusions may be brought into point contact or surface contact with the taper surface. It is preferable. In this way, since the contact area between the misassembly preventing protrusion and the detection means is increased, the fixing strength of the detection means is further increased, and rattling of the detection means can be more reliably suppressed.

  In addition, it is preferable that the protrusion amount of the misassembly prevention protrusion is as large as possible as long as it does not interfere with the detection means when the front cover member is attached to the apparatus main body. If the protrusion of the misassembly prevention protrusion is too small, the front cover member can be attached to the device body even if the misassembly prevention protrusion interferes with the detection means. It becomes difficult to notice wrong assembly of means. In addition, since the detection means cannot be reliably held by the misassembly prevention protrusion, the detection means is likely to be loose. On the other hand, if the amount of protrusion of the misassembly prevention protrusion is too large, the misassembly prevention protrusion and the detection means interfere with each other even though the detection means is correctly mounted. Cannot be attached to the main unit.

  Note that various known structures can be applied to the misassembly preventing protrusion. Examples of the misassembly preventing protrusion include a columnar member and a rib extending along the vertical direction of the front cover member, and a rib is preferable. In this way, since the contact area between the misassembly preventing protrusion and the detection means is increased, the fixing strength of the detection means is further increased, and rattling of the detection means can be more reliably suppressed. Further, only one misassembly preventing projection may be provided for each detection means, or a plurality of misassembly preventing projections may be provided. However, if the misassembly preventing projection is a columnar member, for example. It is preferable that a plurality are provided. Even in this case, since the detection means can be supported by a large number of columnar members, the contact area between the misassembly prevention protrusion and the detection means is increased, so that the fixing strength of the detection means is increased and the detection means The rattling can be suppressed more reliably.

  According to a third aspect of the present invention, in the first or second aspect, when the front cover member is attached to the back surface of the front cover member, the front cover member is locked to the upper surface of the front end portion of the detection means. The gist of the invention is that a game ball guiding piece for guiding the game ball to the rear end side of the detecting means is provided.

  Therefore, according to the third aspect of the present invention, the game ball won in the winning opening can be smoothly guided to the rear end side of the detecting means by the game ball guiding piece. That is, it is possible to solve the problem that the detection means detects the game ball a plurality of times by the game ball bouncing. Further, when the front cover member is attached to the apparatus main body, the game ball guide piece is locked to the upper surface of the front end portion of the detection means, so that the detection means is held not only by the detection means holding part but also by the game ball guide piece. . As a result, the fixing strength of the detection means is improved, and rattling of the detection means is suppressed. Furthermore, when the front cover member is attached to the apparatus main body, the front cover member can be positioned in advance by the game ball guiding piece being locked to the detection means, so that the front cover member can be easily attached.

  Note that it is preferable that a game ball passing portion is formed on the rear end side of the detecting means. In this way, the significance of guiding the game ball with the game ball guiding piece increases. Here, examples of the passing portion of the game ball include a through-hole penetrating the front and back surfaces of the detection means.

  Further, it is preferable that the amount of protrusion of the game ball guiding piece is as large as possible as long as it does not block the game ball passing portion of the detection means. If the protruding amount of the game ball guiding piece is too small, the game ball cannot be smoothly guided to the rear end side of the detection means. In addition, since the detection means cannot be reliably held by the game ball guide piece, the detection means is likely to be rattled. On the other hand, if the amount of protrusion of the game ball guiding piece is too large, the game ball passing portion of the detection means is blocked, and the game ball cannot be detected by the detection means.

  Note that various known structures can be applied to the game ball guide piece. Examples of the game ball guiding piece include a tongue-like plate-like member and a rib extending along the left-right direction of the front cover member, and a rib is preferable. In this way, the game ball guide piece can be easily locked to the upper surface of the front end portion of the detection means, so that the fixing strength of the detection means can be further increased and the play of the detection means can be more reliably suppressed. Further, only one game ball guide piece may be provided for each detection means, or a plurality of game ball guide pieces may be provided. If the game ball guide pieces are, for example, plate-like members, a plurality of game ball guide pieces are provided. It is preferable. Even if it does in this way, since it becomes easy to latch a game ball guide piece to the upper surface of the front-end part of a detection means, while fixing strength of a detection means becomes higher, the rattling of a detection means can be suppressed more reliably.

  As described in detail above, according to the first to third aspects of the present invention, it is possible to provide a gaming machine in which a plurality of detecting means can be efficiently attached to and detached from the winning device. In particular, according to the second aspect, it is easy to notice erroneous assembly of the detection means.

The inner rail 13a and the outer rail 13b define a substantially circular gaming area 12. A part of each rail pin 14 is exposed on the side surface of the inner rail 13a and the side surface of the outer rail 13b. In the game area 12, a guide wheel 16 also called a windmill, a plurality of game nails 21 projecting from almost the entire game area 12, and the like are arranged. The guide wheel 16 and the game nail 21 win the prize devices 30 to 36 and 41 to 43, which will be described later, by changing the direction of the game ball A1 (see FIG. 3 etc.) flowing down in the game area 12. It can be made to. That is, the guide wheel 16 and the game nail 21 play a role in affecting the game result.

  As shown in FIG. 1, an out mouth member 20 that collects the game ball A <b> 1 that has flowed down in the game area 12 is disposed at the bottom of the game area 12. The out port member 20 is sandwiched between the game board 11 and the inner rail 13a. The out port member 20 is fixed to the game board 11 by two rail pins 14 among the plurality of rail pins 14. That is, both rail pins 14 are driven into the game board 11 through the left and right sides of the opening 20a of the out port member 20, respectively.

  In addition, a prize winning device 31 is disposed at a substantially central portion of the game area 12. An upper winning device 30 is disposed above the winning device 31. In addition, a left middle and upper winning device 32 is disposed on the left side of the winning device 31, and a left middle and lower winning device 34 is disposed immediately below the left middle and upper winning device 32. On the other hand, a right middle and upper winning device 33 is disposed on the right side of the winning device 31, and a right middle and lower winning device 35 is disposed immediately below the right middle and upper winning device 33. Further, a central lower prize device 36 is disposed immediately below the prize device 31 in the game area 12. A lower left prize device 37 is disposed on the left side of the central lower prize device 36, and a lower right prize device 38 is disposed on the right side of the central lower prize device 36. Further, a lower winning device 41 is disposed at a position directly below the center lower winning device 36 and directly above the out port member 20.

A detection switch (not shown) for detecting the passage of the game ball A1 is disposed in the back of each of the winning devices 30, 32 to 38, 41 to 43. When the passage of the game ball A1 is detected by these detection switches, a predetermined number (for example, 8) of prize balls are paid out.

As shown in FIG. 1 and the like, each of the winning devices 32 to 36 and 41 to 43 can easily win the game ball A1 with the winning of the gaming ball A1 to the winning devices 31 to 36 and 41 to 43. A pair of blade members 44 (opening and closing members) are provided that can be displaced in an open state or a closed state in which it is difficult to win the game ball A1. The both blade members 44 are in the open state when the upper ends are inclined outward (see the solid line portion in FIG. 1), and are closed when the upper ends are upright (see the broken line portion in FIG. 1). For example, when the game ball A1 wins each of the winning devices 32 to 36, 41, if the vane member 44 of the winning device to which the game ball A1 has won is in the open state, it is displaced to the closed state. In particular, when the game ball A1 wins the winning devices 42 and 43, if the blade member 44 of the winning device to which the game ball A1 wins is open, it is displaced to the closed state, and if it is closed, it is displaced to the open state. It is like that. Further, when the game ball A1 wins the center lower winning device 36, if the blade member 44 of the lower winning device 41 is in the closed state, it is displaced to the open state. Similarly, when the game ball A1 wins the left middle / upward winning device 32, if the blade member 44 of the left middle / lower winning device 34 is closed, the game ball A1 is displaced to the open state, and the game ball A1 enters the right middle / upward winning device 33. When winning, if the blade member 44 of the lower right middle winning device 35 is in the closed state, it is displaced to the open state. That is, the pachinko machine of the present embodiment is a so-called ordinary machine that includes a link mechanism (the interlocking mechanism 61 shown in FIG. 2) and does not include an electric accessory using a solenoid.

  Next, a procedure for attaching and detaching the game ball detection sensor 91 during the actual shooting test will be described. By the way, in the winning device 31 of the present embodiment, no game ball detection sensor is provided at each of the winning ports 56 to 59. Therefore, when performing the real fire test, it is necessary to attach the game ball detection sensor 91 to each of the winning ports 56 to 59 in order to detect the winning game ball A1. Therefore, a process of attaching the game ball detection sensor 91 to each of the winning ports 56 to 59 will be described below.

  First, after removing the screw 104 of the front cover member 101 from the device main body 51 of the winning device 31, the front cover member 101 is removed. Thereby, the front side opening part 82 of each detection sensor holding part 81 is exposed. Next, a game ball detection sensor 91 is inserted vertically into each front opening 82 from the front side of the apparatus main body 51 (see FIGS. 11 and 12), and the rear end surface 91c of the game ball detection sensor 91 is detected by the detection sensor. Engage with the holding piece 84 of the holding portion 81 (see FIG. 10). Thereby, the game ball detection sensor 91 is attached to each detection sensor holding portion 81. Thereafter, the front cover member 101 is disposed on the front side of the apparatus main body 51, and in this state, the screw 104 is inserted into the screw hole 103 and screwed to the apparatus main body 51. As a result, the front cover member 101 is fixed to the apparatus main body 51, and the game ball detection sensors 91 are simultaneously fixed (see FIG. 5 and the like).

  Next, a connector provided at one end of the lead wire is attached to the connector attachment portion of the game ball detection sensor 91, and the other end of the lead wire is connected to an inspection device for a live test. Thereby, the inspection device can pick up the detection signal output from the game ball detection sensor 91. More specifically, the game ball detection sensor 91 detects the game ball A1 that wins the winning ports 56 to 59 and passes through the through hole 92. At this time, a detection signal is output from the game ball detection sensor 91 to the inspection device, and the inspection device inspects each of the winning holes 56 to 59 based on the detection signal (the number of times the game ball A1 has won the winning balls 56 to 59, etc.) Inspection).

  After the real test, the pickup of the detection signal by the inspection device is stopped, the connector provided at one end of the lead wire is removed from the connector mounting portion of the game ball detection sensor 91, and the other end of the lead wire is connected. Remove from the inspection device. Further, the screw 104 of the front cover member 101 is removed from the device main body 51 of the winning device 31, and the front cover member 101 is removed. Thereby, since the front opening 82 of each detection sensor holding part 81 is exposed, the game ball detection sensor 91 can be removed from each front opening 82.

  Therefore, according to the present embodiment, the following effects can be obtained.

  (1) By the way, in the pachinko machine of the present embodiment, the interlocking mechanism 61 that interlocks the blade members 44 of the winning devices 32 to 36 and 41 to 43 is provided so as to surround the winning device 31, so that The component arrangement density on the back side of the board (that is, the back side of the apparatus main body 51) is very high, and the place where the game ball detection sensor 91 is attached is narrow.

  However, in the present embodiment, the game ball detection sensor 91 can be attached to and detached from the detection sensor holding portion 81 not only from the back side of the device body 51 that is narrow, but also from the front side of the device body 51 that is not narrow. Workability at the time of attaching and detaching the ball detection sensor 91 is improved. Moreover, the game ball detection sensor 91 can be attached and detached from both the front side and the back side of the apparatus main body 51 as needed. In addition, the detection sensor holding portion 81 does not have to be damaged by trying to attach or detach the game ball detection sensor 91 from the back side of the apparatus main body 51 with poor workability. Specifically, it is possible to prevent the gaming ball detection sensor 91 from rattling or dropping off due to the holding piece 84 being broken.

  In addition, it is possible to attach to the winning device 31 at the time of manufacture of the pachinko machine according to the desire of the game shop. In this case, since the winning device 31 is attached to the game board 11 after the gaming ball detection sensor 91 is attached to the winning device 31, the back side of the device main body 51 is not narrow when the gaming ball detection sensor 91 is attached. Therefore, the game ball detection sensor 91 can be easily attached and detached from either the front side or the back side of the apparatus main body 51.

  (2) In the present embodiment, since each game ball detection sensor 91 is simultaneously fixed by attaching the front cover member 101 after mounting the game ball detection sensor 91 to each of the plurality of detection sensor holding portions 81, A plurality of game ball detection sensors 91 can be efficiently attached to and detached from the winning device 31.

  (3) By the way, even if a game ball detection sensor having a shape different from that of the regular product is mounted on the detection sensor holding portion 81, the operator may not be aware of incorrect assembly of the game ball detection sensor. Moreover, even if the game ball detection sensor 91 that is a genuine product is mounted upside down, the operator may not notice the incorrect assembly. Moreover, since the winning device 31 of the present embodiment has a plurality of detection sensor holding portions 81, the risk of incorrect assembly is high.

  Therefore, in the present embodiment, the rib 105 is provided on the back surface 101 a of the front cover member 101. As a result, the rib 105 and the game ball detection sensor 91 interfere with each other when the game ball detection sensor having a shape different from that of the regular product is mounted, or when the normal game ball detection sensor 91 is mounted upside down. In addition, the front cover member 101 cannot be attached to the apparatus main body 51. Therefore, the operator is likely to notice incorrect assembly of the game ball detection sensor 91.

  Further, when the front cover member 101 is attached to the apparatus main body 51, the rib 105 abuts against the tapered surface 93 of the game ball detection sensor 91, so that the game ball detection sensor 91 is not only detected by the detection sensor holding portion 81 but also by the rib 105. Retained. Thereby, the fixing strength of the game ball detection sensor 91 is improved and the play of the game ball detection sensor 91 is suppressed.

  (4) The rib 105 of this embodiment is in surface contact with the tapered surface 93 of the game ball detection sensor 91 when the front cover member 101 is attached to the apparatus main body 51, and along the vertical direction of the front cover member 101. Since it extends, the contact area of the rib 105 and the taper surface 93 can be ensured reliably. Therefore, the fixing strength of the game ball detection sensor 91 is further improved, and the play of the game ball detection sensor 91 can be more reliably suppressed.

  (5) Since the game ball guide piece 102 of the present embodiment extends along the left-right direction of the front cover member 101, the contact area between the game ball guide piece 102 and the upper surface 91b of the game ball detection sensor 91 is ensured. It can be secured. Therefore, the fixing strength of the game ball detection sensor 91 is further improved, and the play of the game ball detection sensor 91 can be more reliably suppressed.

  (6) In the front cover member 101 of the present embodiment, all the protrusions such as the game ball guiding piece 102, the rib 105, and the engaging protrusion 106 are provided on the back surface 101a. Thereby, the front and back of the front side cover member 101 can be confirmed by confirming whether it is a surface with a protrusion. Therefore, it is possible to solve the problem that the erroneous assembly is not noticed because the front cover member 101 is attached upside down even though the gaming ball detection sensor 91 is erroneously assembled.

  (7) In the present embodiment, the front cover member 101 is provided with the game ball guiding piece 102, the rib 105, and the engagement protrusion 106, so that the strength of the front cover member 101 is improved.

  In addition, you may change embodiment of this invention as follows.

  In the above embodiment, the front cover member 101 is provided with five game ball guiding pieces 102, five ribs 105, and five engaging protrusions 106, respectively. However, the number of game ball guiding pieces 102, ribs 105, and engagement protrusions 106 may be changed.

  -Although the game ball detection sensor 91 of the said embodiment was attached to the winning device 31 at the time of a real-fire test, it may be attached to the winning device 31 at the time of manufacture of a pachinko machine according to the desire of a game shop. Good. In this case, even if a malfunction occurs in the game ball detection sensor 91, the game ball detection sensor 91 can be removed and replaced from the front side of the winning device 31.

  -Although the game machine of the said embodiment was what is called a normal machine, if the game ball A1 flows down the game area | region 12, another game machine may be sufficient. For example, the gaming machine of the above embodiment may be a so-called “feather” gaming machine. In this case, a game ball detection sensor for paying out a winning ball is provided at the upper part of the winning device, and a specific gaming state (a plurality of blade members are provided in a special winning opening (so-called “V zone”) at the lower part of the winning device. A game ball detection sensor is provided for providing a game state that is opened and closed in rotation. On the other hand, a game ball detection sensor is not provided in the general winning opening at the side of the special winning opening. Therefore, when the game machine is a blade, it is necessary to inspect the winning rate of the game ball A1 to the special winning opening and the general winning opening by attaching a gaming ball detection sensor in the general winning opening when performing the real fire test. There is.
