JP 2003-154110 A

  However, the nail may be loosened due to, for example, countless game balls colliding with the nail during the game. And when a game ball collides with the nail in such a loose state, there is a possibility that the nail will be greatly tilted or dropped. In particular, when a resin game board main body is employed, a pilot hole is generally provided in the game board main body. However, when nails are provided in the lower hole, the above-mentioned fear may occur due to variations in the accuracy of the pilot holes and nails. Becomes more prominent. Furthermore, no matter how hard the nail is driven, the nail may still be in a loose state. In this way, if the nail is tilted or dropped off, the quality of the game ball will be deteriorated as well as the flow path of the game ball will change greatly. The side may suffer a great deal of disadvantage.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a gaming machine having a gaming board body to which nails are firmly attached.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

Means 1. A game board main body having a game area on the front side where a game ball fired by a predetermined launch means is guided;
A gaming machine comprising a nail erected in the gaming area,
A through-hole penetrating in the front-rear direction is provided at a position where the nail of the game board body is disposed,
The nail is
A thread-like projecting portion is formed on one end (base end) side, the thread is screwed and fixed to the game board body, and the other end (leading end) side is provided with a rod-like body portion projecting into the game area. ,
A gaming machine characterized in that a diameter of a part on the other end side of the part where the screw thread is formed is smaller than a diameter of a main body part including the screw thread.

  According to the means 1, a screw thread is formed on one end (base end) side of the main body, and this screw thread is screwed into the game board main body. For this reason, it is possible to firmly attach the nail (the nail for the gaming machine) to the game board main body as compared with the case where a nail in which no thread is formed is driven into the game board main body. Therefore, it is possible to suppress the possibility that the nail will loosen due to collision or vibration of the game ball, adjustment of the projection angle of the nail by hitting the nail in the hole, and the like. Therefore, it is possible to prevent the game ball from colliding with the nail in a loose state, and the possibility that the nail is greatly inclined or dropped off. As a result, the player side or the hall side has a great disadvantage due to the fact that the nail is greatly inclined or dropped, resulting in a decrease in the appearance quality, or the flow path of the game ball greatly changing. It is possible to prevent the possibility of being covered.

  Further, according to this means, the nails are attached to the game board main body in a through-hole penetrating forward and backward, but as described above, the screw thread is screwed into the game board main body. Therefore, for example, even when a nail is struck from the front of the game board main body when adjusting the nail, the movement of the nail to the rear of the game board main body is reliably restricted. Therefore, even when there is no enlarged diameter part in front of the game board main body as in this means, the possibility that the nail will fall out to the rear side of the through hole by being hit from the front of the game board main body is suppressed. can do. Further, for example, when a through hole (a lower hole) penetrating in the front-rear direction is formed in the game board main body in advance, even if a slight manufacturing error occurs in the lower hole or the nail (the diameter of the lower hole is the main body portion) If the error is within the range where the diameter of the pilot hole is smaller than the diameter of the main body including the screw thread, it can be attached. Therefore, it is possible to widen the range of allowable manufacturing errors as compared with the case where nails without threads are driven into the prepared hole.

  In general, a nail that is struck from the front side of the game board main body has a head having a larger diameter than the main body, and the head is arranged so that the head is positioned in front of the game board main body. Yes. However, when the nail is arranged so that the game ball can pass between the predetermined nail and the nail adjacent to the nail, the game ball can pass between the two main body parts, but between the two heads. There is a concern that the diameter of the game ball becomes smaller than that, and in some cases, a ball clogging may occur between the heads. In this respect, according to the present means, there is no portion having a diameter larger than that of the main body portion in front of the game board main body, so that the above problem can be avoided. In addition, since the head of the nail is present in front of the game board main body, it is possible to avoid a situation in which the decoration becomes difficult to see when the decoration is applied to the front surface of the game board main body.

  In addition, since the diameter on the other end side of the part where the screw thread is formed is smaller than the diameter of the main body part including the screw thread, the nail is inserted into the game board main body from the back side of the game board main body. It can be installed through. In this case, work such as nail attachment work and nail projecting length adjustment to the game area is mainly work on the back side of the game board body. It is possible to suppress such a risk that the appearance quality is deteriorated.

  A through hole (a lower hole) penetrating in the front-rear direction may be formed in the game board main body in advance. By forming the pilot hole in this manner, the nail can be easily inserted into the game board main body, and the workability of attaching the nail can be improved. In addition, it is possible to suppress the possibility that the game board main body is deformed or cracked due to forcibly driving or screwing the nails into the game board main body. In particular, when the game board main body is made of resin, these effects become more remarkable. Furthermore, since the nail can be inserted into the game board main body without making the nail tip shape pointed, the design restrictions on the shape of the nail tip exposed to the front of the game board main body can be relaxed. it can. Also, by not making the tip shape of the nail pointed, it is possible to prevent the tip portion from being deformed or damaged by being hit by a game ball or being hit when adjusting the nail. be able to.

  The game board main body may be made of resin. According to the present means, by providing the thread on the nail, the attached state of the nail can be maintained firmly even if the game board body is not so thick, so the thickness of the game board body can be reduced. Therefore, when a cell image or the like is pasted on the back side of a transparent or translucent resin game board body, or when a display device or an accessory such as a liquid crystal device is installed, the game board body is thick. The risk of them becoming difficult to see can be suppressed. Moreover, it is good also as immersing a nail in the back surface of a game board main body. In this case, it is possible to avoid the risk of other members being caught by the nail protruding from the back of the game board main body and being damaged, or by bringing the member provided on the rear side of the game board main body closer to the game board main body. Can be placed.

Mean 2. In the game board main body, a through-hole penetrating in the front-rear direction is formed in advance corresponding to the arrangement position of the nail,
The nail is inserted through the through hole through the other end portion (tip portion) of the main body from the back side of the game board main body, the screw thread is screwed into the game board main body, and the main body portion is inserted into the game area. The gaming machine according to claim 1, having a mounting structure for projecting the other end side.

  According to the means 2, the tip of the main body is inserted into the through hole from the back side of the game board main body, the screw thread is screwed into the inner peripheral surface of the through hole of the game board main body, and the other end of the main body is inserted into the game area. The nail is attached so that the part side protrudes. By adopting this configuration, work such as nail attachment work and nail projecting length adjustment to the game area is mainly work on the back side of the game board body. The fear that the front surface is damaged can be suppressed, and as a result, deterioration in appearance quality can be prevented.

  In addition, since the through hole (lower hole) penetrating in the front-rear direction is formed in the game board main body in advance, the nail can be easily inserted into the game board main body, and the workability of attaching the nail is improved. . In addition, it is possible to suppress the possibility that the game board main body is deformed or cracked due to forcibly driving or screwing the nails into the game board main body. In particular, when the game board main body is made of resin, these effects become more remarkable. Furthermore, since the nail can be inserted into the game board main body without making the nail tip shape pointed, the design restrictions on the shape of the nail tip exposed to the front of the game board main body can be relaxed. it can. Also, by not making the tip shape of the nail pointed, it is possible to prevent the tip portion from being deformed or damaged by being hit by a game ball or being hit when adjusting the nail. be able to. The lower hole is a hole in which a female screw is not formed, and a female screw is formed when the nail is screwed in, so that a separate work process for pre-forming the female screw is omitted. be able to.

  Even if a slight manufacturing error occurs in the pilot holes and nails formed in the game board body (even if the diameter of the pilot hole is slightly larger than the diameter of the main body part), the diameter of the pilot hole is If the error is smaller than the diameter of the main body including the thread, it can be installed, and the range of allowable manufacturing errors can be expanded compared to driving nails without threads in the pilot hole. it can.

  Means 3. A gaming machine according to means 1 or 2, wherein a tool engaging portion is formed at one end of the main body.

  For example, as one method of disposing a threaded nail on a game board main body, it may be possible to gradually screw in by hitting one end of the main body (the base end of the nail). In this case, there is a concern that the nail cannot be screwed in well or that the installation work takes time. Therefore, it is desirable to provide a tool engagement part such as a cross hole for engaging the tip of a tool such as a screwdriver at the base end of the nail, but this tool engagement part is visible from the front side. If it is done, the appearance quality may be significantly reduced. In this regard, as described in the above means 1 or 2, the screw thread provided on the base end side of the main body is screwed into the game board main body, and the front end side of the main body is fixed to the front side of the game board main body. By adopting a structure that protrudes to the base, even when a tool engaging portion is formed at the base end of the nail, the base end is not exposed in front of the game board main body, thereby preventing deterioration in appearance quality. it can.

  And in this means 3, the tool engaging part is formed in the one end part (base end part of a nail) of a main-body part. Thereby, the nail can be screwed by engaging the tip of the tool with the tool engaging portion, and the nail can be attached to the game board main body relatively easily. Therefore, if the nail is not screwed in well and the female board is not formed well in the game board body, the hole through which the nail is inserted becomes too large, or the nail is screwed into the pilot hole in which the female screw is formed, It is possible to suppress the fear that the screw will be crushed and the nail will wobble. Further, it is possible to improve the time efficiency during the nail placement work. Furthermore, since the nail provided with the thread can be removed relatively easily, it is possible to improve the separation workability at the time of recycling. It should be noted that the nail can be removed relatively easily even when the head is not provided on the nail or the base end of the nail provided with the screw thread is immersed in the game board main body.

Means 4. Provided with an enlarged diameter part (head) at one end of the main body,
The gaming machine according to any one of means 1 to 3, wherein the enlarged diameter portion is attached in a state of being substantially in contact with the game board main body.

  In general, when a game ball collides with a nail during a game, the nail may gradually move in the direction of loosening forward. For this reason, for example, when adopting a configuration in which the nail is driven from the front of the game board main body, if the nail is not driven regularly, the nail may be greatly inclined due to the collision of the game ball during the game. Depending on the situation, it may fall off. Also, when adjusting the projection angle of the nail by hitting the nail in the hole, the nail may move in the forward loosening direction, and if you forget to hit the nail after adjusting the nail, There is a risk that the nail will be greatly inclined or fall off due to the collision. In this regard, according to the present means 4, an enlarged diameter portion (head) that contacts the game board main body is provided on the back side of the game board main body, and the forward movement of the nail is restricted. Therefore, even when a nail adjustment is performed or a game ball collides, the nail does not move forward and loosen, and the above problem can be solved.

  Further, since the nail is positioned by the enlarged diameter portion (head) coming into contact with the game board main body, the protruding length of the nail into the game area can be made uniform. In correspondence with the means 3, the tool engaging portion can be formed larger, and the stress applied by the tool can be transmitted to the nail more reliably. Moreover, it will contact | abut with a tool in a wider area, and the malfunction that a tool engaging part will be crushed can also be suppressed.

  Means 5.

  According to the means 5, even if one end portion (base end portion) of the main body portion is flush with the back surface of the game board main body or slightly immersed in the back surface of the game board main body, the screw thread is not exposed to the game area. For this reason, it is possible to avoid the possibility that the screw thread is exposed to the game area and is visually recognized from the front, resulting in a decrease in appearance quality. In addition, by inserting a nail from the back side of the game board main body and attaching it, the possibility of a female screw being formed at the peripheral edge of the nail on the front side of the game board main body or being deformed so as to rise up is suppressed. can do. Accordingly, it is possible to prevent the appearance quality from being deteriorated. In addition, when the thread is formed up to the base end of the main body, there is no “site on one end (base end) side than the part where the thread is formed”. The length of the “formed part” is equal to or less than the thickness of the game board main body. In addition, when the enlarged diameter portion (head) is formed and the head is immersed in the back of the game board main body, the enlarged diameter portion (head) is also “one end portion than the portion where the thread is formed ( It is preferable to be included in the “base end portion side portion”.

At this time, in order to position the gauge in the front-rear direction, the gauge is slid forward to move the gauge. Touch the back of the nail head. Thereby, the measurement position of the distance between the nails is unified, and accurate measurement is achieved. On the other hand, in this means 6, although the head of the nail does not exist in front of the game board main body, the gauge can be positioned by applying a gauge to the step portion instead. Therefore, even if there is no head at the tip of the nail, the distance between the nails at a predetermined position in front of the game board main body can be accurately measured. Furthermore, since the gauge is only applied to the step portion of the nail from the front during measurement, the time until measurement can be shortened. In addition, since the protruding portion of the nail has a small diameter, it is easy to pass the nail through the game board main body (the lower hole).

Further, the central axis of the main body portion 412 and the central axis of the protruding portion 413 are arranged on the same straight line. For this reason, the distance W4 from the connection part (base part of the protrusion part 413) of the protrusion part 413 and the main-body part 412 to the outer peripheral surface of the main-body part 412 is constant. In the present embodiment, the diameter W5 of the protrusion 413 is 1.0 mm. In addition, the tip of the protrusion 413 has an arcuate cross section.

  In addition, the game board main body 30 in which the nail 411 configured as described above is disposed has a lower hole 451 penetrating in the front-rear direction corresponding to the location of the nail 411 (see FIG. 6). The lower hole 451 is formed with an inclination of about 3 to 5 degrees toward the upper front side with respect to the game board main body 30 erected substantially vertically. In the present embodiment, the diameter of the lower hole 451 is slightly larger than the diameter W1 of the main body 412 and smaller than the diameter W2 of the main body 412 including the thread 421 (for example, 2.0 mm to 2.2 mm). It has become. In addition, the lower hole 451 has a taper-shaped enlarged diameter on the back side of the game board main body 30 in order to immerse the head 415 of the nail 411 into the game board main body 30. A female screw is not formed in the lower hole 451, and a female screw is formed when the thread 421 of the nail 411 is screwed into the lower hole 451. Note that the diameter of the lower hole 451 does not necessarily need to be larger than the diameter W1 of the main body portion 412, and may be the same size as the diameter W1 of the main body portion 412 or slightly smaller than the diameter W1 of the main body portion 412. Good.

  Next, the process of attaching the nail 411 will be described. First, on the back side of the game board main body 30, the nail 411 is arranged so that the tip portion (projecting portion 413) of the nail 411 faces the lower hole 451. . Then, the tip end portion (projecting portion 413) of the nail 411 is inserted into the lower hole 451 from the back side of the game board main body 30. As for the portion of the main body 412 where the thread 421 is formed, the tip of the driver is engaged with the cross hole 431 of the head 415 and the screw 421 is screwed into the game board main body 30 by turning the driver. Then, the nail 411 is screwed in until the head 415 is immersed in the back surface of the game board main body 30 and substantially comes into contact with the game board main body 30 to complete the installation.

  As described above in detail, in the present embodiment, the thread 421 is provided on the base end side of the main body portion 412 (general portion 414) (the end portion of the main body portion 412 positioned on the base side of the nail 411 in the attached state). The screw thread 421 is screwed into the game board main body 30. For this reason, the nail 411 can be firmly attached to the game board main body 30 as compared with a case where a nail in which no thread is formed is driven into the game board main body 30. Therefore, it is possible to suppress the possibility that the nail 411 is loosened due to the collision and vibration of the game ball, the adjustment of the projection angle of the nail 411 by hitting the nail 411 in the hole, and the like. For this reason, it is possible to prevent the possibility that the nail 411 is greatly inclined or dropped due to the game ball colliding with the nail 411 in a loose state. As a result, the nail 411 is greatly inclined or dropped, resulting in a decrease in appearance quality, or a significant change in the flow path of the game ball. The possibility of suffering profits can be prevented.

  Furthermore, according to the present embodiment, the nail 411 is attached in the inserted state to the lower hole 451 penetrating forward and backward, but as described above, the screw thread 421 is screwed into the game board main body 30 and fixed. For example, when the nail is adjusted, even if the nail 411 is struck from the front of the game board main body 30, the rearward movement of the nail 411 is reliably restricted. Accordingly, it is possible to suppress the possibility that the nail 411 is pulled out to the rear side of the lower hole 451 by being driven from the front.

  Further, since the screw thread 421 is screwed into the game board main body 30, the mounting state of the nail 411 can be maintained firmly even if the game board main body 30 is not so thick. As a result, the thickness of the game board main body 30 is increased. Can be made thinner. Therefore, when the cell image 401 is affixed to the back surface of the game board main body 30 as in the present embodiment, the possibility that the cell image 401 becomes difficult to see due to the thick game board main body 30 can be suppressed. .

  In general, a nail that is struck to a game board main body has a head that expands at one end of a rod-shaped main body, and the head is positioned in front of the game board main body (game area). Arranged. However, when the nail is arranged so that the game ball can pass between the predetermined nail and the nail adjacent to the nail, the game ball can pass between the two main body parts, but between the two heads. There is a concern that the diameter of the game ball becomes smaller than that, and in some cases, a ball clogging may occur between the heads. In this regard, according to the present embodiment, since the head 415 is not provided in front of the game board main body 30, the above-described problem can be avoided. Further, the presence of the head 415 of the nail 411 in front of the game board main body 30 can avoid a situation in which the decoration is difficult to see when the decoration is applied to the front surface of the game board main body 30. it can. Even if the nail 411 is strongly struck from the front side of the game board main body 30, in this embodiment, the rapid movement of the nail 411 to the rear is restricted by the screw thread 421 screwed into the game board main body 30. Therefore, the possibility that the nail 411 jumps out of the back of the game board main body 30 can be suppressed. As a result, it is possible to avoid a risk that the nail is accidentally driven too much at the time of adjusting the nail and the member disposed on the rear side of the game board main body 30 is damaged.

  Further, since the head 415 that contacts the game board main body 30 is provided on the back side of the game board main body 30, the forward movement of the nail 411 is restricted. Therefore, even when a nail adjustment is performed or a game ball collides, the nail does not move forward and loosen, and the game ball collides during the game and the nail is greatly inclined. It is possible to prevent the possibility of falling or falling off more reliably.

  Furthermore, since the nail 411 is positioned by the head 415 coming into contact with the game board main body 30, the protruding length of the nail 411 into the game area can be made uniform. Further, the cross hole 431 can be formed larger than the case where the head 415 is not provided, and the stress applied by the driver can be transmitted to the nail 411 more reliably. In addition, this can also prevent a problem that the cross hole 431 is crushed.

  Further, for example, as one method of disposing the threaded nail on the game board main body 30, it can be considered that the nail is gradually screwed by hitting the head of the nail. There is a concern that the screw cannot be screwed in well or the installation work takes time. Therefore, it is desirable to provide a cross-hole file or the like for inserting the tip of a screwdriver or the like on the head of the nail. However, if this cross-hole file or the like is viewed from the front side, the appearance quality is remarkable. There is a risk of lowering. In this regard, in the present embodiment, the nail 411 is inserted and attached from the back side of the game board main body 30, so that the head 415 is not exposed to the game area, and the cross hole 431 cannot be seen from the front. As a result, the appearance quality can be prevented from deteriorating.

  In the present embodiment, the cross hole 431 is formed in the head 415. With this, the tip of the driver is engaged with the cross hole 431 and the nail 411 is screwed relatively easily. be able to. Therefore, there is a risk that the nail 411 will not be screwed in well, so that the female board will not be formed well in the game board body 30, or the lower hole 451 through which the nail 411 is inserted will become too large, causing the nail 411 to wobble. Can be deterred. Further, it is possible to improve the time efficiency when the nail 411 is disposed. Furthermore, since the nail 411 provided with the screw thread 421 can be removed relatively easily, it is possible to improve the sorting workability during recycling.

  In general, the distance between the nails is measured by inserting a thin plate gauge between the nails. At this time, in order to position the gauge in the front-rear direction, the gauge is slid forward to Place the gauge on the back of the nail head. Thereby, the measurement position of the distance between the nails is unified, and accurate measurement is achieved. On the other hand, in this embodiment, although the head 415 of the nail 411 does not exist in front of the game board main body 30, the gauge can be positioned by applying a gauge to the stepped portion 441 instead. Therefore, even if the head 415 is not provided at the tip of the nail 411, the distance between the nails 411 at a predetermined position in front of the game board main body 30 can be accurately measured. Furthermore, since the gauge is only applied to the step portion 441 of the nail 411 from the front during measurement, the time until measurement can be shortened. Further, since the tip of the nail 411 has a small diameter, the nail 411 can be easily passed through the lower hole 451. Furthermore, since the tip portion (projecting portion 413) has a reduced diameter, it is possible to make the decoration easy to see when the decoration is applied to the front surface of the game board main body 30.

  Further, since the pilot hole 451 is formed in the game board main body 30 in advance, the nail 411 can be easily inserted into the game board main body 30, and the workability of attaching the nail 411 can be improved. In addition, the risk of the game board main body 30 being deformed or cracked due to forcibly driving or screwing the nails 411 into the game board main body 30 can be suppressed. In particular, in the present embodiment, since the game board main body 30 is made of resin, these effects become more remarkable. Further, since the nail 411 can be inserted into the game board main body 30 without the tip shape of the nail 411 (projecting portion 413) being pointed, the design of the tip shape of the nail 411 exposed in the game area is designed. Restrictions can be relaxed. Further, by not making the tip shape of the nail 411 (projecting portion 413) pointed, the tip portion is deformed or damaged by being hit by a game ball or being hit when adjusting the nail. It is possible to suppress the fear of end. In addition, the lower hole 451 is a hole in which a female screw is not formed, and a female screw is formed when the nail 411 is screwed. Therefore, a separate work process for pre-forming the female screw is omitted. be able to. In this embodiment, since the diameter of the lower hole 451 is slightly larger than the diameter W1 of the main body part 412, the main body part 412 without the thread 421 can be easily inserted into the lower hole 451. Further, since the diameter of the lower hole 451 is smaller than the diameter W2 of the main body portion 412 including the screw thread 421, the screw thread 421 is surely screwed into the game board main body 30, and the nail 411 is firmly attached to the game board main body 30. be able to. Further, even if a slight manufacturing error occurs in the lower hole 451 and the nail 411, if the error is within a range where the diameter of the lower hole 451 is smaller than the diameter W2 of the main body portion 412 including the screw thread 421, it is attached. Compared with a case where a nail without a thread is driven into the prepared hole 451, the range of allowable manufacturing errors can be expanded.

  Further, according to the present embodiment, the length obtained by adding the length L4 (8.5 mm) of the portion of the main body portion 412 where the screw thread 421 is formed and the length L2 (1.1 mm) of the head portion 415. However, the thickness is 9.9 mm or less of the game board main body 30. That is, even if the head 415 is flush with the back of the game board main body 30 or slightly immersed in the back of the game board main body 30, the screw thread 421 is not exposed to the game area. For this reason, the possibility that the thread 421 is exposed to the game area and is visually recognized from the front can cause deterioration in appearance quality. In addition, it is possible to suppress the possibility that a female screw is formed on the periphery of the nail 411 on the front surface of the game board body 30 or that the female screw is deformed so as to rise. Accordingly, it is possible to prevent the appearance quality from being deteriorated.

  In the present embodiment, since the nail 411 (head 415) is immersed in the back surface of the game board main body 30, for example, other members are caught and damaged by the nail protruding from the back surface of the game board main body 30. It is possible to avoid such a risk that the member is provided, or a member provided on the rear side of the game board main body 30 can be arranged closer to the game board main body 30. In addition, since the cross hole 431 is formed in the head 415, the nail 411 can be removed relatively easily even if the head 415 is immersed in the game board main body 30 as in the present embodiment. As a result, it is possible to improve the sorting workability during recycling. The main body portion 412 and the protruding portion 413 are formed in a columnar shape, and the central axis of the main body portion 412 and the central axis of the protruding portion 413 are arranged on the same straight line. The distance W4 to the outer peripheral surface of the part 412 is constant. For this reason, the distance between nails can be measured more accurately.

  Returning to the description of FIG. 3, the variable display device unit 35 triggers a normal symbol display device 41 that displays the normal symbols in a variable manner with the passage of the second trigger corresponding port 34 as a trigger, and a winning to the first trigger corresponding port 33. As a special display device 43 that performs color change display (fluctuation display) of the LED, and a decorative symbol display device 42 as a variable display device that displays the decoration symbol in a variable manner in accordance with the variable display by the special display device 43.

  The normal symbol display device 41 is configured so that “O” or “X” can be lit and displayed as a normal symbol, and each time the game ball passes through the second opportunity corresponding port 34, for example, the normal symbol is changed from “O” to “ The first opportunity corresponding port 33 is predetermined when the change display is fast (change display) such as “×” → “○” →..., And the display is stopped for several seconds with the “○” symbol (winning symbol). It is configured to be activated (opened) only for a period of time. The display contents of the normal symbol display device 41 are directly controlled by a main control device 261 described later. In addition, when a new game ball passes through the second opportunity corresponding port 34 while the normal symbol display device 41 is displaying the normal symbol variation, the corresponding normal symbol variation display is performed at that time. The configuration is performed after the end of the variable display. That is, the variable display is on standby (held). The maximum number of the variable display to be held is determined for each model of the pachinko machine, but in this embodiment, it is held up to 4 times, and the hold number is lit and displayed by the hold lamp 44. Yes.

  Note that the normal symbol may be configured to be variably displayed on a part of the decorative symbol display device 42 (liquid crystal display device), in addition to the configuration to be variably displayed by switching the lighting modes of a plurality of lamps. Similarly, the hold lamp 44 may be configured to be displayed on a part of the decorative symbol display device 42.

  The special display device 43 is provided on the right side of the normal symbol of the normal symbol display device 41, and is configured by a three-color light emitting diode (three-color LED) having emission colors of red, green, and blue. The display content of the special display device 43 is also directly controlled by the main control device 261. In the present embodiment, whether or not a big hit is determined is displayed definitely by the special display device 43.

  The decorative symbol display device 42 is configured as a liquid crystal display device, and the display content is controlled by the sub-control device 262. That is, in the decorative symbol display device 42, auxiliary display contents are determined by the sub-control device 262 based on a command from the main control device 261 so as to correspond to the result displayed on the special display device 43, Display is performed by the display control device 45. The decorative symbol display device 42 displays three symbol rows, upper, middle and lower. Each symbol sequence is composed of a plurality of symbols, and these symbols are scrolled and displayed on the decorative symbol display device 42 so as to be scrolled for each symbol sequence, and then the upper symbol sequence → the lower symbol sequence → the middle symbol sequence. Stops are displayed in order. In the present embodiment, the decorative symbol display device 42 includes an 8-inch size liquid crystal display. The variable display device unit 35 is provided with a center frame 47 so as to surround the decorative symbol display device 42.

  The variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is in an open state in which a game ball is easy to win in the case of a big hit (occurrence of a special game state). More specifically, when a game ball wins the first opportunity corresponding port 33, the special display device 43 displays the three-color LED at a high speed, such as red → green → blue → red →. When a predetermined time elapses, it is determined and displayed in one of the colors. The high-speed color change display is, for example, that red, green, and blue are displayed in order every 4 msec. At this time, if the decision display is made in red or green (for example, stopped for a few seconds), which means that the lottery lottery is won, a big hit state occurs. In addition, when the special display device 43 determines and displays the three-color LEDs in red or green, a combination of specific symbols is supplementarily displayed on the decorative symbol display device 42. The large winning opening of the variable winning device 32 is in a predetermined open state, and the game ball is configured to be in a state where it is easy to win (a big hit state). Specifically, the passage of a predetermined time or a predetermined number of winnings is defined as one round, and the big winning opening of the variable winning device 32 is repeatedly opened a predetermined number of times (a predetermined number of rounds).

  Further, when a game ball is newly won in the first opportunity corresponding port 33 during the variable display of the special display device 43, the corresponding variable display is performed after the end of the variable display at that time. It has a configuration. That is, the variable display is on standby (held). The maximum number of the variable display to be held is determined for each model of the pachinko machine, but in this embodiment, it is held up to 4 times, and the hold number is lit and displayed by the hold lamp 46. Yes. In addition, when a new game ball wins the first opportunity corresponding port 33 during the big hit state, the corresponding change display is also suspended.

  The game board (game board main body 30) is provided with a rail unit 50 as a rail member for guiding the game balls launched from the game ball launching device to the upper part of the game board main body 30, and the handle 18 is turned. A game ball launched in accordance with the operation is guided to a predetermined game area through the rail unit 50. The rail unit 50 has an inner rail component 51 and an outer rail component 52.

  A return ball preventing member 53 is attached to the tip end portion of the inner rail constituting portion 51 (the upper left portion in FIG. 3). This prevents a situation in which the game ball once guided from the ball guide passage between the inner rail constituting portion 51 and the outer rail constituting portion 52 to the upper portion of the game board main body 30 returns to the ball guide passage again. The Further, a return rubber 54 is attached to the outer rail constituting portion 52 at a position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 3: a portion corresponding to the tip portion of the outer rail constituting portion 52). . Therefore, the game ball fired at a predetermined momentum or more hits the return rubber 54 and is returned to, for example, the substantially center portion side of the game board main body 30.
