As described above, there is a pachinko machine as a kind of gaming machine. The pachinko machine is provided with various ball detecting means for detecting a game ball.

For example, in a game area where a launched game ball is guided, various entry means capable of entering the game ball are provided, and game balls that have entered the entry means corresponding to these entry means A ball detection switch is provided for detecting the above.

When the detection signal output from the entrance detection switch is input to the main control device, the main control device performs various controls relating to the game based on these detection signals. For example, when a game ball enters a predetermined entrance means, the main control device transmits a payout command corresponding to the detection result to the payout control device. In addition, when a game ball enters the starting ball entry means, a winning lottery is performed to determine whether or not a big hit state is to be generated, and if a win result is obtained, a big hit state advantageous to the player is generated. When the big hit state occurs, the player can obtain a lot of prize balls by putting the game ball into the big hitting means.

On the other hand, the payout control device drives and controls the payout device so as to pay out the number of prize balls corresponding to the payout command from the main control device. The payout device includes a prize ball detection switch that detects a prize ball that has been paid out, and the payout control device pays out a prize ball as scheduled based on detection information detected by the prize ball detection switch. Know whether or not.

As a general sphere detection switch, many proximity switches that are non-contact type and have excellent durability are employed.

The proximity switch detects the passage of the game ball, for example, by detecting a change in magnetic flux accompanying the passage of the game ball.

More specifically, the proximity switch has a passage hole through which a game ball passes, a detection coil disposed around the passage hole, and a high-frequency oscillation circuit connected to the detection coil. When the game ball passes through the passage hole, an induced current flows through the metal game ball due to electromagnetic induction. In this case, the oscillation amplitude, the oscillation frequency, and the like change in the high-frequency oscillation circuit due to changes in the inductance and loss of the detection coil. By detecting this with the detection circuit, the passage of the game ball can be detected in a non-contact manner. A signal detected by the detection circuit is output to the outside through an output circuit including a comparator.

Under the above configuration, in a normal state where the game ball does not pass through the passage hole, a low level signal is output from the output terminal of the proximity switch, while on the other hand, when the game ball passes through the passage hole, the high level is output. A signal is output. The main control device can detect that the game ball has passed by detecting the change in the signal level (see, for example, Patent Document 1).

However, in general, the size of the ball passage to which the proximity switch is attached is formed larger than the size of the passage hole of the proximity switch so as not to hinder the flow of the game ball. Therefore, there is a possibility that the game ball flowing down collides with the peripheral hole of the proximity switch exposed in the ball passage, causing the proximity switch to break or break down.

The present invention has been made to solve the above-described problems and the like, and an object thereof is to provide a gaming machine capable of suppressing the occurrence of a failure or the like.

  However, as shown in FIG. 18, the prize opening switch 221 in this embodiment is a position that is a predetermined distance away from the upper surface portion 221f to the lower surface portion 221g side in the through direction of the passage hole 221d (vertical direction in FIG. 18). A section from x1 to a position x2 further apart by a predetermined length is set as a detection range L. That is, when the game ball B passes through the passage hole 221d of the winning hole switch 221 and its lower end Ba reaches the detection range L, the game ball B starts to be detected, and its upper end Bb passes the detection range L. At the end, the detection of the game ball B ends. In the present embodiment, the diameter of the regular game ball B is 11 mm, whereas the diameter W1 of the pass hole 221d of the prize opening switch 221 is set to 11.4 mm, for example, and the thickness from the upper surface portion 221f to the lower surface portion 221g. W2 is set to 6.0 mm, the distance W3 from the upper surface part 221f to the position x1 is set to 8.6 mm, and the section of the detection range L is set to 2.7 mm. Of course, the dimensions of the winning opening switch 221 and its detection range L are not limited to this, and can be changed as appropriate.

  On the other hand, when the game ball passes through the passage hole 221d (detection range L), a low level signal having a reference potential of 0 V is output. Therefore, a low level signal is normally input to the CPU 501 of the main controller 261 via the inverting circuit 229, and a high level signal is input when the passage of a game ball is detected.

  For example, when the game ball passes through the passage hole 221d of the winning hole switch 221, as shown in FIG. 19A, the oscillation amplitude, oscillation frequency, etc. of the high-frequency oscillation circuit during the passage of the game ball (time TS <b> 1 to TS <b> 2). As shown in FIG. 19B, the input level of the main controller 261 is switched from the low level (L) to the high level (H).

  The reason why the winning opening switch 221 outputs a high level signal during normal time and outputs a low level signal during game ball detection is to prevent erroneous detection by the CPU 501 of the main controller 261.

  In a configuration in which a low level signal is output during normal time and a high level signal is output when a game ball is detected as in the prior art, noise is applied to the electrical path 228 between the winning port switch 221 and the main control device 261. There is a possibility that the CPU 501 may mistakenly recognize that a game ball has passed though it has been input to the main control device 261 as a high level signal, and the game ball has not actually passed through the prize opening switch 221. there were. Causes of noise include static electricity generated by various electronic devices, vibrations caused by the player shaking or hitting the pachinko machine 10, and the like.

  Although not described in detail, the winning port switch 221 is also related to the relationship between the other ball detection switches (count switch 223, first trigger corresponding unit switch 224, second trigger corresponding port switch 225) and the main controller 261. It is the same composition as.

  Subsequently, a switch reading process periodically performed by the CPU 501 of the main control device 261 will be described in detail. In this switch reading process, each ball detection switch (winning port switch 221, count switch 223, first opportunity corresponding unit switch 224, second opportunity corresponding port switch 225) is individually monitored and the same individually. Processing is performed. Accordingly, here, the switch reading process related to the winning opening switch 221 will be described in detail with reference to FIG. 20 as an example, but the same process as the process shown in FIG.

  First, in step S6001, the signal level of the input signal from the winning opening switch 221 is checked. The function of this processing constitutes the signal monitoring means in this embodiment.

  For example, when the game ball is not passing through the passage hole 221d (detection range L) of the winning opening switch 221, a high level signal (H) of + 12V is output from the winning opening switch 221 [timing shown in FIG. On the main controller 261 side, a low level signal (L) having a reference potential of 0 V is input to the CPU 501 via the inverting circuit 229 (see timing t1 in FIG. 21B). FIG. 21A is a timing chart for explaining an output signal from the winning opening switch 221, and FIG. 21B is a timing chart for explaining an input signal to the CPU 501.

  On the other hand, while a game ball enters the general winning port 31 and the game ball passes through the passage hole 221d (detection range L) of the winning port switch 221, a low level signal ( L) is output (see timings t2 and t3 in FIG. 21A), and the high level signal (H) is input to the CPU 501 through the inverting circuit 229 on the main controller 261 side [timing in FIG. 21B]. t2, t3 reference].

  In the subsequent step S6002, the signal level checked in step S6001 is stored in the signal level buffer for the winning opening switch 221 provided in the work area of the RAM 503.

  The signal level buffer is provided corresponding to each incoming detection switch (award opening switch 221, count switch 223, first opportunity corresponding unit switch 224, second opportunity corresponding opening switch 225). The signal level for each detection switch is stored. The signal level buffer corresponds to the level storage means in this embodiment.

  The signal level buffer is configured by a ring buffer. In the ring buffer, the start address and the end address in the buffer area are conceptually connected in a ring shape, and the write address and the read pointer are used to write sequentially from the start address and reach the end address. This buffer is controlled so that it can be written back to the start address again. After data is written at a predetermined address position indicated by the write pointer, the value of the write pointer is updated to a value indicating the next address. Similarly, after data is read from a predetermined address position indicated by the read pointer, the value of the read pointer is updated to a value indicating the next address.

  In addition, the latest 200 msec data, that is, 100 cycles of data is stored in the ring buffer that constitutes each signal level buffer of this embodiment, and the oldest data beyond this is erased in order. Yes. Further, the position of the read pointer indicates a predetermined address position where the latest data is stored. As described later, the data for the past plural times is read based on the position of the read pointer. .

  Returning to the description of step S6002, each time the signal level is checked at a cycle of 2 msec, a logical value corresponding to the signal level is sequentially written in a predetermined address position indicated by the write pointer in the signal level buffer for the winning opening switch 221. To go. Here, when the signal level of the input signal to the CPU 501 is “H (high)”, a logical value “1” is stored as level information indicating this, and the signal level is “L (low)”. Stores a logical value “0” as level information indicating this.

  Thereafter, in step S6003, a calculation process which is a pre-process for determining whether or not a game ball has entered the general winning opening 31 is performed.

  More specifically, logical inversion processing is performed on the earliest data (oldest data) of the latest three data stored in the signal level buffer, and the earliest data that has been logically inverted and the remaining 2 data. Calculate the logical product of all the batch data. Then, this value is temporarily stored in the work area of the RAM 503. The function of this processing constitutes the logic inversion means and the logical product calculation means in this embodiment.

  For example, as shown in FIG. 21B, when the logical values of the signal levels stored at timings t1, t2, and t3 are “0”, “1”, and “1”, the logical inversion of the earliest data When processing is performed, the earliest data is “1”. Therefore, the logical product of this data and the other two data is “1”.

  In the subsequent step S6004, it is determined whether or not the logical product value calculated in step S6003 is “1”. Here, when the logical product value is “1”, it means that the signal level has been switched from “L” to “H”. In step S6005, “1” is set to the value of the ball entry discrimination flag for the winning hole switch 221 (general winning hole 31), and this process is terminated. In addition, the entrance discrimination flag is a discriminator for discriminating whether or not there is an entrance and is provided corresponding to each entrance detection switch. Then, main controller 261 determines whether or not there is a ball in the subsequent processing.

  On the other hand, when the logical product value is “0”, the signal level remains “L” or “H” for the past 4 msec, or the signal level does not switch from “H” to “L”. Therefore, it is determined that there is no entry to the general winning opening 31, and in step S6006, the value of the entering determination flag for the winning opening switch 221 is set to “0”. Exit. The function of the series of processing (entrance determination processing) in steps S6003 to S6006 described above constitutes the entrance determination means in the present embodiment.

  Now, proximity switches such as the prize opening switch 221 have been subject to various illegal acts.

  For example, in the related art, as shown in FIGS. 24A and 24B, as a mounting structure for inserting the proximity switch 900 into the ball passage 901 and fixing it, a position facing the mounting hole 902 into which the proximity switch 900 is inserted. In addition, there is known one in which a concave holding portion 903 for holding the insertion side distal end portion 900a of the proximity switch 900 is formed. However, like the ball collection member 216 of the present application, the ball passage component member 905 is generally integrally formed of a resin material. Therefore, in the conventional configuration, when the ball passage component member 905 is molded, For the convenience of die-cutting the mold H for forming the concave shape (a pair of protruding portions 903a and 903b), and between the upstream edge portion 902a of the mounting hole 902 and the upper surface portion 900b of the proximity switch 900, and mounting Clearances K1 and K2 were formed between the downstream edge portion 902b of the hole 902 and the lower surface portion 900c of the proximity switch 900. For this reason, there is a possibility that a fraudulent act may be performed such that a wire or the like enters the ball passage 901 from the gaps K1 and K2, the wire or the like is inserted into the passage hole 900d of the proximity switch 900, and the proximity switch 900 malfunctions. .

  On the other hand, the mounting hole 406 in the present embodiment has an opening width Y1 along the vertical direction that is substantially the same as the vertical width of the winning opening switch 221, and the opening width Y2 along the left and right direction has a winning opening. The switch 221 is formed to have substantially the same width as the left and right width. Thus, when the winning opening switch 221 is attached to the attachment hole 406, no gap is formed between them. As a result, fraudulent acts as described above can be suppressed.

  As described above, when the ball collecting member 216 is formed so that no gap is formed between the mounting hole 406 and the winning opening switch 221, a concave holding portion that holds the front end portion of the winning opening switch 221 is formed. This makes it impossible to make the winning opening switch 221 in an unstable state.

  On the other hand, in this embodiment, in addition to the support portions 411 and 412 on the back surface side of the bulging portion 405 and the groove portions 413 and 414 on the wall surfaces of the ribs 402 and 403, the upper edge portion of the mounting hole 406 and the bulging portion 405 Extending pieces 407 and 408 extending from the lower edge portion toward the inside of the passage are provided. Thus, in the attached state of the winning opening switch 221, the extended pieces 407, 408 are in surface contact with and support the upper surface portion 221 f and the lower surface portion 221 g of the winning opening switch 221, so that a sufficient holding amount is obtained. Can be secured, and the winning opening switch 221 can be stably held.

  It should be noted that if only the upper surface portion 221f and the lower surface portion 221g of the winning opening switch 221 are in surface contact and a relatively large contact area is ensured, the bulging portion 405 is not provided and the outside of the passage is formed from the mounting hole 406. A configuration is also possible in which the extension piece is formed to extend toward the surface. However, in such a configuration, the extension piece projecting outward from the passage from the upper edge portion and the lower edge portion of the attachment hole 406 becomes an obstacle, and the attachment hole 406 is formed. There is a risk that it will be difficult to perform the work of attaching the prize opening switch 221 to the.

  In this respect, in the present embodiment, a bulging portion 405 bulging from the inner side to the outer side of the ball passage 231 is provided, and the upper and lower edges of the mounting hole 406 formed here are respectively provided to the ball passage 231. By extending the inwardly extending pieces 407 and 408, the contact area with the winning port switch 221 is secured relatively large, but does not obstruct the mounting operation of the winning port switch 221. .

  The pachinko machine 10 according to the present embodiment is installed in an inclined manner so that the upper part of the game board 30 is located more rearward in a game hall or the like in order to properly flow down the game ball. That is, the game ball flows down along the back wall 401 of the ball collection member 216 in the ball passage 231. For this reason, in this embodiment, the extended pieces 407 and 408 protruding to the inside of the ball passage 231 function as a restricting means that weakens the downward flow of the game ball. When a restricting portion (see the restricting portion 450 in FIG. 10) is provided in a normal passage section, the protruding amount of the restricting portion cannot be increased so much due to the size of the ball passage 231 and the game ball. By projecting the extending pieces 407 and 408 toward the inside of the passage from the bulging portion 405 bulging outward from the passage as in the embodiment, the protruding amount of the extending pieces 407 and 408 is made relatively large. Therefore, a larger effect can be obtained as a regulating means.

  Further, by providing the bulging portion 405, even if a wire or the like is intruded along the back side of the back wall portion 401 of the ball collection member 216, the bulging portion 405 causes the wire or the like to move outward from the passage. Since the direction can be changed, it becomes more difficult to enter a wire or the like into the ball passage 231.

  In addition, in the present embodiment, of the end edge portions 407a and 408a of the extension pieces 407 and 408, the portion located on the rear side (the bulging portion 405 side) from the center of the passage hole 221d of the prize opening switch 221 is: It is formed in a substantially arc shape along the peripheral shape of the passage hole 221d. As a result, the end edges 407a and 408a of the extended pieces 407 and 408 can be extended to the limit position reaching the peripheral edge of the passage hole 221d, and therefore supported to a position closer to the front end of the winning port switch 221 that is not held. In addition, it is possible to secure a larger contact area with the winning opening switch 221. If the edge portions 407a, 408a of the extended pieces 407, 408 are linear along the left-right direction, the winning hole switch is used to prevent the passage holes 221d from being blocked by the extended pieces 407, 408. It becomes difficult to ensure a relatively large contact area with 221.

  In the present embodiment, the extension pieces 407 and 408 also support the side portion of the winning opening switch 221 and hold the three sides of the spherical passage 231 having a substantially rectangular cross section. It is possible to stabilize the attached state of the winning opening switch 221 inside.

  Furthermore, in the present embodiment, by providing the extended pieces 407 and 408, it is possible to prevent the game ball from directly and vigorously colliding with the periphery of the passage hole 221d of the winning port switch 221, and the winning port switch 221. It is possible to suppress the occurrence of breakage or failure in

  When a proximity switch such as the above-described prize opening switch 221 is used, the magnetic field around the detection coil may change due to the influence of external radio waves. For this reason, conventionally, there has been a risk that a fraudulent act of intentionally causing the proximity switch to malfunction, that is, a so-called “radio wave” is performed using a device that transmits radio waves.

  For example, a fraudulent act with respect to a ball entry detection switch such as a prize port switch 221 that artificially increases the number of balls entered into the general prize port 31 will be described. As shown in FIG. 22A, by inserting a radio wave having a shorter transmission time (time TK1 to TK2) while the game ball is passing (time TS1 to TS2), as shown in FIG. As shown in FIG. 22B, the input level of the main control device 261 is at the low level (L) during the time TK1 to TK2. In other words, the signal level is switched twice while the game ball is passing (time TS1 to TS2), and in reality there are two game balls that have entered the general winning opening 31 and the like. It is possible to make a false detection that there is a minute of entry. In this way, for example, if an illegal act is performed with respect to the first opportunity corresponding port switch 224 of the first opportunity corresponding port 33, the game hits the jackpot even though the game ball does not enter the first opportunity corresponding port 33. Extra lottery opportunities will be obtained.

  In addition, a regular game ball (diameter 11.0 mm) and a game ball having a diameter larger than the passage hole 221d (diameter 11.4 mm) of the prize opening switch 221 (hereinafter referred to as “illegal large sphere”. For example, a diameter 11.8 mm). ) Is also conceivable. In such a case, first, the illegal large ball is put into the ball passage 231 in advance by winning the general winning opening 31 or the like. Then, the illegal large sphere cannot pass through the passage hole 221d of the winning hole switch 221 and is caught in the passage hole 221d. As a result, the winning opening switch 221 is always in a state (on state) in which an illegal large ball is detected. In this state, by appropriately transmitting an improper radio wave [see FIG. 22 (a)] that makes the winning opening switch 221 in the non-detection state (off state), the on / off state is switched and the game ball is not passing. Regardless, it can be erroneously detected that the game ball has passed. However, the target of such fraudulent acts is limited to a ball detection switch arranged on the back side of the pachinko machine 10 that cannot be visually recognized by the player, such as a prize opening switch 221. This is because it is unlikely that an illegal large ball is set in advance for a ball detection switch that is visible to the player from the front side of the pachinko machine 10, such as the first opportunity corresponding port switch 224. .

  In the method of artificially increasing the number of balls entered in the previous stage, the game balls must actually be awarded to the general prize opening 31 and the like, and the timing of passing through the prize opening switch 221 must be matched to insert unauthorized radio waves. It is difficult to do realistically. On the other hand, since the method using the illegal large sphere in the latter stage is relatively easy to execute, a means for effectively preventing such illegal acts is required.

  In this regard, the winning opening switch 221 in the present embodiment has a detection range L in the vertical direction from a position x1 that is a predetermined distance away from the upper surface portion 221f to the lower surface portion 221g side. Is set as. That is, the detection range L in which the game ball can be detected is set at a position where an illegal large sphere that cannot pass through the passage hole 221d does not reach even in a state where the illegal large sphere is fitted to the passage hole 221d from the upstream side. As a result, it is possible to suppress illegal acts using the illegal large sphere as described above.

  However, in the case where the illegal large sphere is formed in a distorted shape such as an elliptical shape, a part of the illegal large sphere can be obtained by simply setting the detection range L of the winning opening switch 221 as described above. It may reach the detection range L of 221 and the effect may be insufficient.

  In this regard, in the present embodiment, the provision of the extended piece 407 on the upstream side of the winning opening switch 221 makes it possible to keep the illegal large ball in the upstream position. It is possible to further enhance the effect of suppressing fraud using the.

  Next, a fraudulent act on a payout count switch or the like that cancels the detection of the passing of the game ball by transmitting radio waves for a time longer than the game ball passing time TS1 to TS2 will be described. As shown in FIG. 23 (a), as shown in FIG. 23 (a), as shown in FIG. 23 (a), as shown in FIG. 23 (a), by sending radio waves for a time longer than the game ball passage time TS1-TS2, The input level 311 is maintained at the low level (L) without switching to the high level (H). That is, the prize ball is actually paid out, and the passing of the prize ball is not detected even though the prize ball passes through the payout count switch. As a result, the payout control device 311 executes the payout process again, and the fraudulent person can acquire an excessive number of prize balls in excess of a preset number.

  However, such a method is actually inefficient because it is necessary to actually win the game ball to the general winning opening 31 and the like, and the payout control device 311 is processed as a payout error after a predetermined time has elapsed. Not right. On the other hand, if a gap similar to the gaps K1 and K2 (see FIG. 24) is formed between the payout count switch and its mounting hole, a wire or the like enters the ball path from the gap. In the payout device 358, an unauthorized radio wave that cancels the detection of the passing of the gaming ball as described above is transmitted while the gaming ball is caused to flow down by illegally operating a regulating member such as a sprocket that regulates the flow of the gaming ball. This makes it possible to illegally acquire a large number of game balls.

  Such a fraudulent act can be sufficiently dealt with by adopting the mounting structure of the winning opening switch 221 in the present embodiment as the mounting structure of the payout count switch.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) In the above embodiment, when performing the ball entering determination process, the logic inversion process of the earliest data among the latest three data stored in the signal level buffer is performed and the logic inversion is performed. The logical product of all the data and the remaining two data is calculated, and the determination process is performed based on the calculation result. However, the present invention is not limited to this, and the same processing may be performed based on at least two times of data stored in the signal level buffer. Alternatively, the logical inversion processing of the earliest data may be omitted, and a logical product of data for a plurality of times may be simply calculated.

  (B) In a configuration in which other ball start detection switches such as the count switch 223 and the first opportunity corresponding port switch 224 are mounted on the ball collection member 216, the ball port detection switch 221 in the above embodiment is also mounted on the ball detection switch. A mounting structure similar to the structure may be adopted.

  (C) The ball path constituent member to which the ball detection switch is attached is not limited to the ball collecting member 216, but may be a variable prize device or a payout device, for example, as long as the ball path through which a game ball passes is formed. Other members may be used.

  (D) The configuration, such as the shape and size of the bulging portion 405, is not limited to the above embodiment. For example, the bulging part 405 may be configured to bulge to substantially the same position as the rear end part of the winning prize opening switch 221.

  Further, on the back side of the bulging portion 405, for example, a curved chamfered portion may be formed on the peripheral portion of the mounting hole 406. Thereby, it becomes easy to perform the work of attaching the winning opening switch 221.

  (E) The configuration of the extending pieces 407 and 408, such as the shape and size thereof, is not limited to the above embodiment.

  For example, a configuration in which the front side (game board 30 side) portion from the center of the passage hole 221d of the winning port switch 221 may be omitted. In the case where the effect of suppressing the illegal act using the illegal large sphere as described above or the effect as the restricting means is enhanced, the extended pieces 407, 408, etc. around the passage hole 221d of the winning opening switch 221 Although it is preferable to form the covering portion, such a configuration may cause the ball passage to become narrow and the game ball may not flow smoothly. In this regard, if the extension pieces 407 and 408 are provided at least at a position located on the rear side (the bulging portion 405 side) from the center of the passage hole 221d of the winning hole switch 221, the occurrence of such a problem is suppressed. However, it is possible to more effectively exhibit the effect of suppressing the illegal act using the illegal large sphere and the effect as the regulating means. Of course, from the viewpoint of avoiding the collision of the game ball with the winning port switch 221, it is preferable that an extending piece (protective piece) is formed around the entire passage hole 221 d of the winning port switch 221.

  Moreover, in the said embodiment, about the part located in the rear side (the bulging part 405 side) from the center of the passage hole 221d of the winning opening switch 221 among edge part 407a, 408a of the extended piece 407,408, It is formed in a substantially arc shape along the peripheral shape of the passage hole 221d. Not limited to this, from the viewpoint of avoiding the collision of the game ball with the winning opening switch 221, the passage hole of the portion located on the front side (the game board 30 side) from the center of the passing hole 221 d of the winning opening switch 221 is also used. It is preferably formed in a substantially arc shape along the peripheral shape of 221d.

  In the above-described embodiment, the extending pieces 407 and 408 are provided in substantially the entire upper edge portion and lower edge portion of the attachment hole 406 along the left-right direction so as to connect the ribs 402 and 403. Not only this but the structure where the extension piece (protection piece) was each formed separately, for example in the corner part which rib 402 and the bulging part 405 contact, and the corner part which rib 403 and the bulging part 405 contact | connect It is good.

  (F) Depending on the configuration of the bulging portion 405 and the extending pieces 407 and 408, the supporting portions 411 and 412, the groove portions 413 and 414, the regulating piece 415, and the like may be omitted.

  (G) In the above embodiment, the detection range L of the winning opening switch 221 is set at a position further away from the lower surface portion 221g, but the detection range L is limited to the range of the above embodiment. It is not something. For example, the upper limit position of the detection range L may be the position of the lower surface portion 221g. Further, as in the prior art, the detection range L may be set to a section in the passage hole 221d. However, from the viewpoint of suppressing the illegal act using the illegal large sphere as described above, at least the detection range L is the radius of the passage hole 221d from the upper surface portion 221f of the prize opening switch 221 (the maximum diameter that can pass through the passage hole 221d). It is preferable that the spheres are separated from each other by at least the radius. That is, it is preferable that the detection range L is set at a position where an illegal large sphere that cannot pass through the passage hole 221d does not reach even in a state of being fitted to the passage hole 221d from the upstream side.

  (H) In the above-described embodiment, the winning opening switch 221 is attached to the ball collection member 216 in a state where its longitudinal direction is along the front-rear direction. Not limited to this, the winning opening switch 221 may be attached to the ball collection member 216 in a state where the longitudinal direction of the winning prize switch is along the left-right direction. In such a case, for example, the support portion 411 or the like is omitted, and a slit communicating with the mounting hole 406 is formed in the bulging portion 405, the rib 402, or the like, and the longitudinal direction of the winning opening switch 221 is set along the left-right direction. In such a state, it is possible to adopt an attachment structure or the like in which the winning opening switch 221 is inserted into the ball passage 231 from the back side of the ball passage 231 toward the front.

  (I) In the above embodiment, the winning opening switch 221 is attached in the passage section extending along the vertical direction. However, the present invention is not limited to this, and for example, the winning opening switch 221 is formed in a section in which the passage is inclined obliquely. It is good also as a structure which attaches.

  (J) In the above embodiment, a proximity switch that detects the passage of the game ball by detecting a change in magnetic flux accompanying the passage of the game ball is employed as the ball detection means. However, the present invention is not limited to this, and other configurations such as a switch for detecting passage of a game ball by an optical sensor may be adopted.

  (K) You may implement as a different type of pachinko machine from the above-mentioned embodiment. In addition to pachinko machines, various game machines such as an arrangement ball machine and a sparrow ball similar thereto may be used.

  (L) In the above embodiment, from the viewpoint of suppressing the complexity of the manufacturing process and the increase in production cost, the ball collection member 216 is integrally formed of a resin material. From the viewpoint of avoiding the collision of the game ball with the winning opening switch 221, the ball collecting member 216 is formed by combining a plurality of members in order to form an extending piece (protective piece) around the entire passage hole 221 d of the winning opening switch 221. It is good also as a structure formed using the metal mold | die apparatus which performs complicated operation | movement which die-cuts a metal mold | die in many directions, such as front and back, right and left.

  (M) From the viewpoint of avoiding the collision of the game ball with the winning port switch 221, the bulging portion 405 may be omitted as long as the extension piece 407 and the like are formed.

  (N) The extension piece 407 or the like may be configured not to contact the prize opening switch 221 as long as the extension piece 407 or the like is formed from the viewpoint of avoiding the collision of the game ball with the prize opening switch 221.

  Hereinafter, the technical idea that is not described in the claims and that can be grasped from the above embodiment will be described together with the effects thereof.

Means 1. A ball passage component having a ball passage through which a game ball can flow down;
A ball detecting means having a passage hole through which a game ball can pass and capable of detecting a game ball passing through the passage hole;
In the gaming machine in which the ball detecting means is attached to the ball path component so that the passage hole faces the ball path,
The ball passage component is
The ball detection means extends from the inner wall surface of the ball passage along the upper surface of the ball detection means toward the inside of the ball passage, and at least a part of the edge of the ball detection means extends along the peripheral shape of the passage hole of the ball detection means. The gaming machine according to means 1, further comprising an extended piece (protective piece) formed.

  According to the means 1, by providing the extending piece, it is possible to prevent the game ball from directly and vigorously colliding with the periphery of the passage hole of the ball detecting means, and the ball detecting means is damaged or broken. The risk of doing so can be reduced.

  Mean 2. 2. The gaming machine according to claim 1, wherein the extended piece is in contact with at least the upper surface of the ball detecting means in the attached state of the ball detecting means.

  According to the means 2, no gap is generated between the extended piece and the upper surface portion of the sphere detecting means, and the operational effect of the means 1 can be made more reliable.

Means 3. A game ball is configured to flow down along a predetermined wall portion (for example, a back wall portion) of the ball passage,
The gaming machine according to claim 1 or 2, wherein the extending piece is formed at least in a range closer to the predetermined wall portion than the center position of the passage hole of the ball detecting means.

  In order to enhance the effect as the restricting means for suppressing the collision of the game balls as described above, it is preferable to form the extending piece around the entire passage hole of the ball detecting means. There is a possibility that the passage becomes narrow and the game ball does not flow smoothly. In this respect, according to the means 3, the effect as the regulating means can be more effectively exhibited while suppressing the occurrence of such a problem.

Means 4. In a part of the predetermined wall portion, provided with a bulging portion bulging from the inside of the ball passage toward the outside,
The gaming machine according to claim 3, wherein the extended piece is provided in the bulging portion.

  When an extension piece is provided in a normal passage section, the protruding amount of the extension piece cannot be increased so much due to the size of the passage and the game ball. Since the protruding amount of the extending piece can be made relatively large by projecting the extending piece from the protruded bulging portion toward the inside of the passage, a larger effect can be obtained as a restricting means. .

Means 5. In the bulging portion, the opening width of the game ball along the flow-down direction is formed to be substantially the same as the vertical width of the ball detection means along the penetration direction of the passage hole, and the ball detection means is connected to the ball passage. It has a mounting hole that can be inserted into the inside,
The extending pieces extend from the upstream edge and the downstream edge of the mounting hole toward the inside of the spherical passage,
The gaming machine according to claim 4, wherein in the attached state of the ball detecting means, the two extending pieces are in contact with the upper surface portion and the lower surface portion of the ball detecting means.

As a mounting structure for inserting and fixing the sphere detection means into the sphere passage, a concave holding portion for holding the insertion side tip of the sphere detection means is formed at a position facing the mounting hole for inserting the sphere detection means. Things have been known for some time. However, in general, since the ball passage component is integrally formed of a resin material or the like, in the conventional configuration, when the ball passage component is molded, a pair of protruding portions of the concave holding portion is formed. For convenience of die removal, gaps are formed between the upstream edge of the mounting hole and the top surface of the ball detecting means, and between the downstream edge of the mounting hole and the bottom surface of the ball detecting means. It had been. For this reason, there is a possibility that a fraudulent act may be performed such that a wire or the like enters the ball passage from the gap, the wire or the like is inserted into the passage hole of the ball detection unit, and the ball detection unit malfunctions. Of course, it is not impossible to form the concave holding portion without generating the gap by using a mold apparatus that performs a complicated operation such as punching the mold in multiple directions such as front, rear, left and right. In such a case, problems such as complication of the manufacturing process and an increase in production cost are caused. In this respect, the means 5 has an opening width of the mounting hole along the flow direction of the game ball (passage direction). By forming substantially the same width as the vertical width of the sphere detection means, between the upstream edge of the mounting hole and the upper surface of the sphere detection means, and the downstream edge of the mounting hole and the lower surface of the sphere detection means No gap is formed between the two. Thereby, fraudulent acts as described above can be suppressed.

  As described above, the sphere is formed so that no gap is formed between the upstream edge of the mounting hole and the upper surface of the sphere detecting means, and between the downstream edge of the mounting hole and the lower surface of the sphere detecting means. In the case of forming the passage component member, it is impossible to form a concave holding portion that holds the insertion-side tip of the sphere detection means, so that the mounting state of the sphere detection means may be unstable.

  On the other hand, it is conceivable to stabilize the mounting state by forming a groove portion into which the side portion of the sphere detection means is fitted along the insertion direction of the sphere detection means on the inner wall surface of the sphere passage. However, the distance between the side portion of the sphere detecting means and the peripheral portion of the passage hole is relatively short, and it is difficult to secure a sufficient holding amount by itself.

  In this respect, in the present means 5, the extending pieces formed to extend from the upstream edge and the downstream edge of the mounting hole toward the inside of the spherical passage respectively face the upper surface portion and the lower surface portion of the ball detecting means. Since it abuts and supports it, the ball detecting means can be stably held.

  If the surface is simply abutted against the upper surface and the lower surface of the sphere detecting means and a relatively large contact area is ensured, the bulging portion is not provided, and the holding is performed from the mounting hole toward the outside of the passage. Although a configuration in which the extending piece for extension is formed is also conceivable, in such a configuration, the extending piece for holding protruding outward from the passage from the upstream edge portion and the downstream edge portion of the mounting hole becomes an obstacle, There is a possibility that it is difficult to perform the work of attaching the ball detecting means to the mounting hole.

  In this respect, the present means 5 is provided with a bulging portion that bulges from the inner side to the outer side of the ball passage, and from the upstream edge portion and the downstream edge portion of the mounting hole formed here to the inside of the ball passage. By using the extension piece for restriction formed so as to extend toward the surface, a relatively large contact area with the ball detection means can be secured, but the work for mounting the ball detection means is not obstructed.

  At this time, when the edge of the extended piece is linear, it is possible to ensure a relatively large contact area with the ball detecting means in order not to block the passage hole with the extended piece. It becomes difficult. In addition, in a configuration that does not have a groove portion into which the side portion of the sphere detection means is fitted, the sphere detection means is held only on one side (bulge portion side) of the spherical passage having a substantially rectangular cross section. There is a possibility that the mounting state of the ball detecting means in the ball passage becomes unstable.

  In this regard, as described above, at least a part of the end edge portion of the extension piece is formed along the peripheral shape of the passage hole of the sphere detecting means, so that the end edge portion of the extension piece is made to pass through the passage hole. Since it can extend to the limit position reaching the peripheral edge, it can be supported to a position closer to the insertion side tip of the sphere detection means that is not held, and a larger contact area with the sphere detection means is ensured. be able to. In addition, since it supports at least a part of the side portion of the sphere detection means and holds the three sides of the spherical passage having a substantially rectangular cross section (the corner portion of at least one side and two sides in contact with the side), The mounting state of the sphere detection means in the sphere passage can be stabilized.

Means 6. A launching means for launching a game ball;
A game board having a game area on the front side where a launched game ball is guided;
In a gaming machine comprising a pitching means arranged in the gaming area,
The flow path component is a member attached to the back side of the game board,
The gaming machine according to any one of means 1 to 5, wherein the ball detecting means is a ball entering detecting means for detecting a game ball that has entered the ball entering means.

  In order to allow the game ball to flow down properly, the gaming machine configured as the above means 6 is installed at an inclination so that the upper part of the game board is located further rearward in a game hall or the like. For this reason, it can be made to function as a control means as mentioned above by providing at least the above-mentioned extension piece on the back side of a channel constituent member (ball passage).

  Mean 7 The gaming machine according to any one of means 1 to 6, wherein the ball detection means is a proximity switch that detects the passage of the game ball by detecting a change in magnetic flux accompanying the passage of the game ball.

  When a proximity switch such as this means is used as a sphere detection means, the magnetic field around the detection coil may change due to the influence of external radio waves. For this reason, conventionally, there has been a risk that a fraudulent act of intentionally causing the proximity switch to malfunction, that is, a so-called “radio wave” is performed using a device that transmits radio waves.

  As one of such radio wave methods, for example, a method using a game ball having a diameter larger than that of a regular game ball (hereinafter referred to as “illegal large ball”) can be considered. In such a case, an illegal large sphere is first placed in the ball passage in advance. Then, the illegal large sphere cannot pass through the passage hole of the sphere detection means and is caught by the passage hole. Thereby, the sphere detection means is always in a state (on state) in which an illegal large sphere is detected. In this state, by appropriately transmitting an improper radio wave that makes the ball detection means non-detection state (off state), the on / off state is switched, and the game ball has passed even though the game ball has not passed. False detection can be made.

  In this respect, the provision of the extending piece upstream of the sphere detection means makes it possible to keep the illegal large sphere at a position that does not reach the detection range of the sphere detection means. Can be suppressed.

  Means 8. The ball detecting means can detect a game ball passing through the passage hole, and a detection range of a game ball (a ball having a diameter larger than the diameter of the passage hole) that cannot pass through the passage hole is the passage hole. The gaming machine according to any one of means 1 to 7, wherein the gaming machine is set at a position that does not reach even when fitted from the upstream side.

  For example, an example in which the detection range is more than the radius of the passage hole (the radius of the largest diameter sphere that can pass through the passage hole) from the upper surface portion of the sphere detection unit with respect to the penetration direction of the passage hole. .

  According to the means 8, it is possible to further enhance the effect of suppressing illegal acts using the illegal large sphere as described above. For example, when the illegal large sphere is formed in a distorted shape such as an elliptical shape, a part of the illegal large sphere is detected by the sphere detecting means only by providing the above-mentioned extending piece upstream of the sphere detecting means. It may reach the range, and the effect may be insufficient.

  Means 9. The gaming machine according to any one of means 1 to 8, wherein the gaming machine is a ball and ball gaming machine (for example, a pachinko machine or a gaming machine equivalent to a pachinko machine).

  For example, a bullet ball gaming machine is provided with game value giving means for giving a predetermined game value based on the entry of a game ball into a predetermined ball entry means. Here, to give a game value, for example, paying out a prize ball, performing a lottery as to whether or not to generate a special game state advantageous to a player, and displaying identification information in a variable manner. included.
