In a cash machine in which game balls are lent directly to the upper plate 19 from a ball lending device or the like without using a card unit, the card unit connection board 314 can be omitted.

  The launch control device 312 permits or prohibits the launch of the game ball by the launch device 60, and the launch device 60 is permitted to drive when predetermined conditions are met. Specifically, a firing permission signal is output from the payout control device 311, a sensor signal is detected that the player is touching the handle 18, and a firing stop switch that stops firing is operated. On the condition that it is not done, the launching device 60 is driven, and the game ball is launched at an intensity corresponding to the operation amount of the handle 18.

  The display control device 45 executes the variable display of the decorative symbols on the decorative symbol display device 42 in accordance with an instruction from the sub-control device 262. The display control device 45 includes a CPU 521, a program ROM 522, a work RAM 523, a video RAM 524, a character ROM 525, a video display processor (VDP) 526, an input port 527, an output port 529, and bus lines 530 and 531. And. An input / output port 554 of the sub control device 262 is connected to the input port 527. Further, a CPU 521, a program ROM 522, a work RAM 523, and a VDP 526 are connected to the input port 527 through a bus line 530. An output port 529 is connected to the VDP 526 via a bus line 531, and a decorative symbol display device 42 as a liquid crystal display device is connected to the output port 529.

  The CPU 521 of the display control device 45 receives the display command transmitted from the sub-control device 262 via the input port 527, analyzes the received command, or performs predetermined arithmetic processing based on the received command to control the VDP 526. (Specifically, generation of an internal command for the VDP 526) is performed. Thereby, display control in the decorative symbol display device 42 is performed.

  The program ROM 522 is a memory that stores various control programs executed by the CPU 521 and fixed value data. The work RAM 523 is a memory that temporarily stores work data and flags used when the CPU 521 executes various programs. It is.

  The video RAM 524 is a memory for storing display data to be displayed on the decorative symbol display device 42, and the display content of the decorative symbol display device 42 is changed by rewriting the contents of the video RAM 524. The character ROM 525 is a memory that stores character data such as symbols displayed on the decorative symbol display device 42.

  The VDP 526 is a kind of drawing circuit that directly operates an LCD driver (liquid crystal driving circuit) incorporated in the decorative symbol display device 42. Since the VDP 526 is an IC chip, it is also referred to as a “drawing chip”, and the substance of the VDP 526 can be said to be a microcomputer chip with a dedicated firmware for drawing processing. The VDP 526 adjusts the respective timings of the CPU 521, the video RAM 524, etc. to intervene in reading and writing data, and reads the display data stored in the video RAM 524 at a predetermined timing and causes the decorative symbol display device 42 to display it.

  The power supply device 313 includes a power supply unit 541 that supplies power to each unit of the pachinko machine 10, a power failure monitoring circuit 542 that monitors power interruption due to a power failure, and a RAM erase switch circuit 543 connected to the RAM erase switch 323. And.

  The power supply unit 541 supplies necessary operation power to the main control device 261, the payout control device 311 and the like through a power supply path (not shown). As its outline, the power supply unit 541 takes in AC 24 volt power supplied from the outside, generates + 12V power for driving various switches and motors, + 5V power for logic, backup power for RAM backup, etc. These + 12V power supply, + 5V power supply and backup power supply are supplied to the main control device 261, the payout control device 311 and the like. Note that operation power (+12 V power, +5 V power, etc.) is supplied to the launch control device 312 via the payout control device 311. Similarly, operating power is supplied to various switches, motors and the like via a control device to which these are connected.

  The power failure monitoring circuit 542 is a circuit that outputs a power failure signal SK1 to each NMI terminal of the CPU 501 of the main control device 261 and the CPU 511 of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like. The power failure monitoring circuit 542 monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 541, and determines that a power failure (power failure) has occurred when this voltage is less than 22 volts. The power failure signal SK1 is output to the main controller 261 and the payout controller 311. Based on the output of the power failure signal SK1, the main control device 261 and the payout control device 311 recognize the occurrence of a power failure and execute a power failure process (NMI interrupt processing).

  The power supply unit 541 normally outputs an output of 5 volts, which is a drive voltage of the control system, for a time sufficient to execute the process at the time of a power failure even after the DC stable voltage of 24 volts becomes less than 22 volts. Configured to maintain the value. Therefore, the main control device 261 and the payout control device 311 can normally execute and complete the power failure process.

  The RAM erase switch circuit 543 is a circuit that takes in the switch signal of the RAM erase switch 323 and clears backup data in the RAM 503 of the main controller 261 and the RAM 513 of the payout controller 311 in accordance with the state of the switch 323. When the RAM erase switch 323 is pressed, the RAM erase switch circuit 543 outputs a RAM erase signal SK2 to the main controller 261 and the payout controller 311. When the power of the pachinko machine 10 is turned on with the RAM erase switch 323 pressed (including power-on due to power failure cancellation), the data in the respective RAMs 503 and 513 are cleared in the main controller 261 and the payout controller 311. The

  As described above in detail, according to the present embodiment, the game nail 401 includes the enlarged diameter portion 412 having a larger diameter than the overhang portion 403 projecting into the game area, and the overhang portion 403 includes the enlarged diameter portion 412. It extends from. In other words, the diameter near the root portion of the overhang portion 403 is relatively large. For this reason, for example, when an external force is applied to the overhang portion 403 due to a collision of a game ball or the like, even if a relatively large stress acts near the root portion of the overhang portion 403, the root portion of the overhang portion 403 A situation in which the game nail 401 is broken or unnecessarily deformed in the vicinity can be suppressed. Therefore, the durability of the game nail 401 can be improved, and as a result, the game board 30 (pachinko machine 10) that can withstand long-term use can be obtained.

  Furthermore, since the overhang portion 403 is not thickened, but the main body portion 402 is thickened, the space for moving the game ball moving in the game area is reduced due to the overhang portion 403 becoming thick. Such a situation can be avoided.

  Further, for example, due to a manufacturing error, the game nail 401 is attached to be tilted, or the game nail 401 or an accessory installed in the game area (for example, the top winning opening 33a or the center frame 47) is arranged. In such a case, the game nail 401 may be intentionally bent by hitting the overhang portion 403 and the projection angle of the game nail 401 (movement path of the game ball) may be adjusted. At this time, for example, when the boundary portion (the front end portion of the enlarged diameter portion 412) between the main body portion 402 and the overhang portion 403 is located at a position where it is greatly immersed from the front surface of the game board main body 30a, the game nail 401 bent by the above adjustment There is a concern that the overhanging portion 403 abuts against the opening peripheral edge of the lower hole 431. In particular, when the strength of the game board main body 30a is high, even if an attempt is made to bend the overhanging portion 403 around its base portion, it is bent at a portion of the overhanging portion 403 that is in contact with the peripheral edge of the lower hole 431. As a result, the above-described effects may not be successfully achieved. In addition, when the strength of the game board main body 30a is low, the gaming periphery of the lower hole 431 is caused by the gaming nail 401 (the overhanging portion 403) bent during the adjustment being pressed against the opening peripheral portion of the lower hole 431. The part may be damaged (the lower hole 431 is widened or cracked).

  On the other hand, according to the present embodiment, the boundary portion (the front end portion of the enlarged diameter portion 412) between the main body portion 402 and the overhang portion 403 is positioned in front of the front surface of the game board main body 30a in the front-rear direction. Therefore, at the time of the adjustment, the game nail 401 can be reliably bent around the boundary portion between the enlarged diameter portion 412 and the overhang portion 403 (near the root portion of the overhang portion 403). The effect is reliably achieved. In the above adjustment, the game nail 401 is basically bent in front of the game board main body 30a, so that it is possible to prevent the game board main body 30a from being damaged by the bent game nail 401.

  Further, the front end portion of the enlarged diameter portion 412 is tapered. Therefore, it is possible to disperse the stress acting near the boundary portion between the overhang portion 403 and the enlarged diameter portion 412 (near the root portion of the overhang portion 403), and the stress concentrates on the portion, so that the game nail 401 becomes the portion. It is possible to more reliably prevent a situation such as breaking in the process.

  Further, the diameter of the lower hole 431 through which the game nail 401 is inserted is substantially the same as the diameter of the enlarged diameter portion 412, and the enlarged diameter portion 412 is brought into a substantially contact state with the inner peripheral surface of the lower hole 431. . Therefore, when the game nail 401 is bent, the enlarged diameter portion 412 is supported by the game board main body 30a (the inner peripheral surface of the lower hole 431), and deformation of the enlarged diameter portion 412 is restricted. For this reason, when the game nail 401 is bent, it is possible to prevent a situation in which a relatively large stress acts on the fixed portion 411 (the fixed portion 411 is deformed relatively large). In particular, due to the presence of the enlarged diameter portion 412 between the fixing portion 411 and the overhang portion 403, when an external force is applied to the overhang portion 403, stress is applied to the fixing portion 411. The situation can be suppressed more reliably. As a result, the attached state of the game nail 401 can be stabilized. Furthermore, since the fixed portion 411 itself has a trough having a diameter larger than the diameter of the overhang portion 403, the situation where the game nail 401 breaks at the fixed portion 411 (the trough) is more reliably prevented. be able to.

  In addition, the game nail 401 is inserted from a rear side of the game board main body 30a into a prepared hole 431 formed in advance in the game board main body 30a, and is attached to the game board main body 30a. Therefore, the mounting operation of the game nail 401 is mainly performed on the rear side of the game board main body 30a, so that the possibility that the front surface of the game board main body 30a is damaged during the mounting operation or the like can be suppressed. As a result, it is possible to prevent deterioration of the appearance quality. Furthermore, when attaching the game nail 401, it is not necessary to apply a force directly to the overhanging portion 403, so that it is possible to prevent the overhanging portion 403 from being deformed, and avoid problems caused by this. it can. In addition, since it is not necessary to provide a tool engaging portion such as the cross hole 405 at the front end portion of the game nail 401, it is possible to prevent deterioration in appearance quality.

  Furthermore, since the lower hole 431 is formed in the game board main body 30a, the game nail 401 can be attached to the game board main body 30a relatively easily, and workability is improved. Further, it is possible to suppress the possibility that the game board main body 30a (particularly the front surface) is deformed or cracked due to the game board main body 30a being forcibly driven or screwed into the game board main body 30a. Further, since the game nail 401 can be attached to the game board main body 30a without the tip shape of the game nail 401 being pointed, the design of the shape of the tip of the game nail 401 exposed in front of the game board main body 30a. Can be relaxed.

  Further, for example, if the protruding length of the game nail 401 (the overhang portion 403) protruding forward from the front surface of the game board main body 30a becomes too short, the game nail of the present embodiment in which the front end portion of the overhang portion 403 does not have a head. Concerning 401, there is a concern that the game ball that should originally be played by the game nail 401 will not be played. For this reason, it is conceivable that an illegal act of shortening the protruding length of the game nail 401 to make it easier to enter the game ball into the top winning opening 33a or the warp flow path 152 may be performed. If such fraud is made, there is a concern that the game hall will suffer a great disadvantage.

  On the other hand, in the present embodiment, the front side of the main body 402 that is embedded in the game board main body 30a is a diameter-enlarged portion 412 in which the male screw 414 is not formed, and the male screw 414 is formed and the game board is formed. The fixing portion 411 fixed to the main body 30 a exists only on the rear side of the main body portion 402. For this reason, the fixing portion 411 cannot be fixed to the game board main body 30a unless the overhang portion 403 is protruded to some extent in the game area. Therefore, by fixing the game nail 401 to the game board main body 30a, the protruding length of the overhang portion 403 is inevitably secured to some extent, and the protruding length of the overhang portion 403 is prevented from becoming too short as described above. can do.

  In addition, since the male screw 414 is not exposed to the game area, the male screw 414 is visually recognized from the front, a female screw is formed at the peripheral edge of the lower hole 431 on the front surface of the game board main body 30a, or the peripheral edge of the lower hole 431 is raised. Thus, it is possible to prevent the appearance quality from being deteriorated due to deformation.

  Furthermore, the game nail 401 is disposed at a position where the collision frequency of game balls is higher than that of other board nails (in the vicinity of the top winning port 33a and the ball inlet 151 of the warp channel 152). For this reason, the game board 30 (pachinko machine 10) which can endure long-term use can be obtained reliably. Moreover, the round nail used conventionally is used for the board surface nail arrange | positioned in another position. For this reason, it is possible to prevent a sense of incongruity caused by the renewal of all board nails erected in the game area, and to reduce the cost of the board nails.

  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, the overhang portion 403 extends from the enlarged diameter portion 412. For example, as shown in FIG. 10A, a fixed portion 411 is formed on the front side of the main body portion 402, and the overhang portion is formed. 403 may be extended from the fixed portion 411. Further, for example, the entire body portion 402 (the entire formation range of the fixed portion 411 and the enlarged diameter portion 412 in the above embodiment) may be the fixed portion 411. As described above, when the overhanging portion 403 extends from the fixing portion 411, the diameter of the fixing portion 411 (the valley portion) is configured to be larger than the diameter of the overhanging portion 403. However, when these configurations are employed, if an external force is applied to the overhang portion 403, stress may be concentrated on the valley portion of the fixing portion 411 on which the male screw 414 is formed. As described above, it is desirable to provide the enlarged diameter portion 412 that can contact the inner peripheral surface of the lower hole 431 in front of the fixing portion 411.

  Further, in the above-described embodiment, the diameter of the valley portion of the fixed portion 411 may be the same as or larger than the diameter of the enlarged diameter portion 412. In this case, the attached state of the game nail 401 can be further stabilized. In addition, the diameter of the valley portion of the fixed portion 411 may be smaller than the diameter of the overhang portion 403. Even in the case where the configuration is adopted, the fixed portion 411 is stressed by adopting a configuration in which the enlarged diameter portion 412 absorbs the external force applied when the external force is applied to the overhang portion 403 as in the above embodiment. Therefore, it is possible to avoid a situation in which the fixing portion 411 is broken.

  Although not particularly mentioned in the above embodiment, the male screw 414 in the fixing portion 411 may be formed by threading or may be formed by rolling with a rolling machine or the like.

  (B) Also, for example, as shown in FIG. 10B, the head 404 provided at the rear end of the game nail 401 may be omitted. In this case, for example, it is possible to avoid a situation in which the head 404 is visually recognized through the transparent game board main body 30a and the appearance quality is deteriorated. In FIG. 10B, a tool engaging portion (cross hole 405) is formed on the rear end surface of the main body portion 402 (fixed portion 411).

  Furthermore, the shape of the front end portion of the game nail 401 (the overhang portion 403) is not particularly limited. For example, as shown in FIG. 10B, the front end portion of the game nail 401 has a diameter larger than that of the overhang portion 403. A large nail head 701 may be provided. In this case, the appearance of the game nail 401 can be brought close to other board nails (round nails), and the uncomfortable feeling due to the difference in appearance can be suppressed. Further, by providing a nail head 701 at the front end, a plate gauge is applied to the back side of the nail head 701 as in the past, and a predetermined game nail 401 and a board nail (game nail 401 or a round nail) adjacent thereto are provided. The distance between the tip portions can be measured relatively easily. When the game nail 401 is attached from the rear side of the game board main body 30a, the diameter of the nail head 701 is configured to be smaller than the diameter of the lower hole 431 in order to pass the nail head 701 through the lower hole 431.

  (C) In the above embodiment, the front end portion of the main body portion 402 (expanded diameter portion 412) is the overhang portion 403 of the game nail 401, the front surface of the game board main body 30a, and the front surface of the overhang portion 403 and the game board main body 30a. Is located in a space surrounded by game balls that are in contact with both, but the front end portion of the main body portion 402 is substantially the same as the front surface of the game board main body 30a in the front-rear direction or from the front surface of the game board main body 30a. Also, it may be configured to be located rearward (see FIG. 10B). However, if the front end portion of the enlarged diameter portion 412 is located at a position where the front end of the game board main body 30a is relatively deeply immersed, the peripheral edge portion of the lower hole 431 on the front surface of the game board main body 30a is pressed and damaged. The overhanging portion 403 does not bend around the base portion, but is bent at a portion in contact with the peripheral edge of the lower hole 431 on the front surface of the game board main body 30a. May not be played. For this reason, it is desirable that the boundary portion between the enlarged diameter portion 412 and the overhang portion 403 is disposed at a position that is not so much immersed from the front surface of the game board main body 30a, and further, the front surface of the game board main body 30a in the front-back direction. It is desirable to be located at substantially the same position as that of the game board main body 30a.

  (D) In the above embodiment, the diameter of the enlarged diameter portion 412 and the inner diameter of the lower hole 431 are configured to be substantially the same, and the outer peripheral surface of the enlarged diameter portion 412 and the inner peripheral surface of the lower hole 431 are substantially in contact. However, for example, as shown in FIG. 10C, the lower hole 431 is configured to be larger than the enlarged diameter portion 412, so that the outer peripheral surface of the enlarged diameter portion 412 and the inner peripheral surface of the lower hole 431 can be ensured. It may be separated. However, if the gap between the enlarged diameter portion 412 and the inner peripheral surface of the lower hole 431 becomes too large, the enlarged diameter portion 412 may be relatively greatly deformed when the game nail 401 is bent. In this case, there is a concern that a relatively large stress acts on the fixing portion 411 and the mounting state is deteriorated. Accordingly, it is desirable that the diameter-expanded portion 412 is configured to be able to contact the inner peripheral surface of the lower hole 431 when the game nail 401 is deformed at a relatively small extent (within the elastic limit). . With this configuration, when the game nail 401 is bent, the enlarged diameter portion 412 abuts against the game board main body 30a, so that deformation of the enlarged diameter portion 412 is limited, and when the game nail 401 is bent. A situation in which a relatively large stress acts on the fixing portion 411 can be prevented.

  It is also possible to form the lower hole 431 slightly smaller than the enlarged diameter part 412 and attach the game nail 401 to the game board main body 30a so that the enlarged diameter part 412 comes into pressure contact with the game board main body 30a. In this case, the above-described effects can be achieved more reliably.

  (E) In the above embodiment, the game nail 401 is inserted into the lower hole 431 from the rear side of the game board main body 30a, but the game nail 401 may be inserted into the lower hole 431 from the front side of the game board main body 30a. Good. When the game nail 401 is screwed into the game board main body 30a from the front surface of the game board main body 30a, a cross hole 405 or the like that engages with the tip of the tool (driver) is formed at the front end of the game nail 401. There is a risk that the appearance quality will be significantly reduced. Therefore, the male screw 414 is omitted, and the game nail 401 is fixed to the game board main body 30a by press-fitting the game nail 401 into the lower hole 431, or the game nail 401 is attached from the rear side of the game board main body 30a as in the above embodiment. It is desirable.

  Hereinafter, an example of a case where the game nail is screwed from the front side of the game board main body 30a will be described with reference to FIG. A game nail 701 shown in FIG. 11A extends from the front end of the main body 702 to a columnar main body 702 that is fixed in a state of being inserted in the front-rear direction with respect to the game board main body 30a. And a columnar overhanging portion 703 protruding into the game area. The main body 702 includes a fixing portion 711 in which a male screw 714 is formed, and a diameter-expanding portion 712 that extends forward from the front end portion of the fixing portion 711 and has a larger diameter than the overhang portion 703. The game nail 701 is inserted and screwed into the lower hole 431 from the front side of the game board main body 30a, and is attached to the game board main body 30a.

  Further, a substantially disc-shaped skirt portion 721 that protrudes outward from the outer peripheral surface of the enlarged-diameter portion 712 and contacts the front surface of the game board main body 30a at the front end portion (boundary portion with the overhang portion 703) of the enlarged-diameter portion 712. Is provided. Due to the presence of the skirt portion 721, even when the peripheral edge of the lower hole 431 on the front surface of the game board main body 30 a is scratched by the male screw 714 when the game nail 701 is attached, the peripheral edge of the lower hole 431 is caused by the skirt portion 721. The portion is covered, and deterioration in appearance quality can be prevented. In addition, the protruding length of the game nail 701 can be defined.

  Further, the skirt portion 721 is provided with an engaging portion 722 that engages with a tool used when the game nail 701 is screwed to the game board main body 30a. By engaging the tool with the engaging portion 722 and screwing the game nail 701, it is not necessary to hit the overhanging portion 703 when attaching the game nail 701. Therefore, the game nail 701 can be removed without bending the overhanging portion 703. Can be installed reliably. Note that the boundary portion between the skirt portion 721 and the overhang portion 703 may be tapered.

  (F) Further, the male nail 414 of the fixing portion 411 is omitted, the game nail 401 is press-fitted into the lower hole 431, and the outer peripheral surface of the fixing portion 411 and the inner peripheral surface of the lower hole 431 are pressed into contact with each other. 401 may be held (attached). In this case, since the game nail 401 can be attached to the game board main body 30a only by pushing the game nail 401 into the lower hole 431, it is possible to improve the attachment workability. Hereinafter, exemplary embodiments will be described with reference to FIGS. 12 and 13.

  (F-1) A game nail 801 shown in FIG. 12 extends from the front end of the main body 802 to a cylindrical main body 802 that is fixed in a state of being inserted in the front-rear direction with respect to the game board main body 30a. A columnar projecting portion 803 that protrudes into the game area and a head portion 804 provided at the rear end portion of the main body portion 802 are provided. The diameter of the main body portion 802 is slightly larger than the inner diameter of the lower hole 431 formed in the game board main body 30a, and the diameter of the overhang portion 803 is smaller than the diameters of the main body portion 802 and the lower hole 431. In addition, the front end portion of the main body portion 802 is configured in a tapered shape with a diameter reduced toward the overhang portion 803. In this configuration, the main body 802 constitutes a fixed portion and a diameter-expanded portion.

  The game nail 801 is press-fitted into the lower hole 431 from the rear side of the game board main body 30a and attached to the game board main body 30a. Thus, by attaching the game nail 801 from the rear side of the game board main body 30a, it is not necessary to directly apply an external force to the overhang portion 803 when attaching the game nail 801. Therefore, the game nail 801 (the overhang portion 803) It is possible to prevent the possibility of deformation. Further, in the mounted state of the game nail 801, the front end portion of the head 804 is in contact with the rear surface of the game board main body 30a. As a result, the protruding length of the game nail 801 is defined, and the game nail 801 is prevented from being pulled forward.

  Furthermore, the head 804 includes an engaging portion 805 that engages with a tool (nail-out) at a position spaced from the rear surface of the game board main body 30a. Thus, by providing the engaging portion 805, the game nail 801 can be removed relatively easily (even if the overhang portion 803 is broken) without damaging the game board main body 30a. This improves workability during maintenance and recycling.

  Note that the game nail 801 shown in FIG. 12 is configured so that the main body 802 has the same diameter in any part, but is not particularly limited to such a configuration. For example, the diameter of the front portion of the main body portion 802 may be configured to be smaller than the diameter of the rear side of the main body portion 802 and larger than the diameter of the overhang portion 803. In this case, the front portion of the main body 802 is configured to be able to contact the inner peripheral surface of the lower hole 431 when a relatively small deformation occurs at least to the extent that the game nail 801 is bent (within the elastic limit). It is desirable that

  (F-2) A game nail 901 shown in FIG. 13A is a cylindrical main body 902 that is fixed in a state of being inserted in the front-rear direction with respect to the game board main body 30a, and a front end of the main body 902. A columnar overhanging portion 903 that extends forward and protrudes into the game area is provided. The diameter of the main body portion 902 is slightly larger than the inner diameter of the lower hole 431 formed in the game board main body 30a, and the diameter of the overhang portion 903 is smaller than the diameters of the main body portion 902 and the lower hole 431. In addition, the front end portion of the main body portion 902 has a tapered shape with a diameter reduced toward the overhang portion 903. In this configuration, the main body 802 constitutes a fixed portion and a diameter-expanded portion.

  The game nail 901 is press-fitted into the lower hole 431 from the front side of the game board main body 30a and attached to the game board main body 30a. In this way, by attaching the game nail 901 from the front side of the game board main body 30a, for example, even when the cell image 30b is attached to the front surface of the game board main body 30a, the game nail 901 is caused by the attachment. Thus, it is possible to avoid a situation in which the cell image 30b at the periphery of the lower hole 431 is lifted. In addition, since the game nail 901 is fixed by being press-fitted into the game board main body 30a, for example, a tool engaging portion such as a cross hole is formed on the front end portion for screwing the game nail 901. There is no need, and deterioration of the appearance quality can be prevented.

  Further, the game nail 901 is provided with a substantially C-shaped handle (engagement portion) 921 for hooking a tool at the rear end portion, so that the game board main body 30a is not damaged (in the unlikely event, the overhang portion 903). The game nail 901 can be removed relatively easily (even in the case where the game has broken).

  Further, in the attached state shown in FIG. 13A, the rear end portion of the game nail 901 is located in front of the rear surface of the game board main body 30a. For this reason, for example, even if the cell image 30b is attached to the rear surface of the game board main body 30a, it is possible to avoid a situation in which the cell image 30b is pushed by the game nail 901 and floats. Note that in the mounted state of the game nail 901, the rear end portion of the game nail 901 may be flush with the rear surface of the game board main body 30a.

  Furthermore, when the game nail 901 is attached, if the front end portion of the game nail 901 is simply hit with a hammer or the like, the overhang portion 903 may be bent. For this reason, as shown in FIG.13 (b), the front part of the main-body part 902 is pressed using the driving means 950 which comprises the nail pad part 951 which can contact | abut to the front surface (taper surface) of the main-body part 902, The game nail 901 may be press-fitted into the lower hole 431. That is, since there is a step between the main body portion 902 and the overhang portion 903, the game nail 901 can be attached to the game board main body 30a by pressing the step without pressing the overhang portion 903. . In this case, the game nail 901 can be securely attached without bending the overhang portion 903. In addition, the projecting length of the game nail 901 can be made constant by driving the game nail 901 into the game board main body 30a until the nail contact portion 951 comes into contact with the game board main body 30a (cell image 30b).

  (G) In the above embodiment, the game board main body 30a is made of a transparent resin, but may be made of a translucent or opaque resin, or may be made of wood (plywood or the like). In the above-described embodiment, for example, a display device such as a liquid crystal display device, a light emitting unit, and an accessory, or a combination thereof may be installed facing the rear surface of the game board main body 30a. . In this case, they can be visually recognized from the front through the game board main body 30a. Therefore, it is possible to give a more gorgeous decoration or perform more various effects without narrowing the area where the game ball can move in the game area, and to improve the entertainment. In the above embodiment, if the cell image 30b is affixed to the front surface of the game board main body 30a at the site where the game nail 401 is disposed, the cell image 30b peels off and floats when the game nail 401 is inserted. Therefore, it is preferable not to attach the cell image 30b to the front surface of the game board main body 30a at such a part. In addition, when adopting the wooden game board main body 30a, etc., when it is necessary to affix the cell image 30b to the part where the game nail 401 is disposed on the front surface of the game board main body 30a, the game nail 401 Then, a sticker having a hole through which the game nail 401 can be inserted may be attached to the front surface of the game board main body 30a, and the peripheral part of the lower hole 431 may be covered by the seal.

  (H) Although not specifically mentioned in the above embodiment, a nail housing portion for housing a replacement game nail may be provided in the pachinko machine 10 (for example, the rear surface of the game board main body 30a). By providing the game nail for replacement in this way, it is possible to improve the workability of replacing the game nail 401 that cannot substitute for other board nails.

  In addition, the game nail for replacement is compared with the game nail 401 before replacement. (1) When the fixed portion 411 is attached to the front side of the game nail 401 in the mounting direction (when the game nail 401 is mounted from the rear side of the game board main body 30a). May be formed to the front), or (2) the fixed portion 411 may have a large diameter. In this case, when the replacement game nail is attached, a new female screw is formed by cutting away the uncut portion of the inner peripheral surface of the lower hole 431 where the game nail 401 before replacement is disposed. Can do. Therefore, it is possible to stabilize the mounting state of the replacement game screw.

  When the configuration (1) is adopted, the main body 402 is configured such that the front end side in the mounting direction to the game board main body 30a is configured as the enlarged diameter portion 412 and the rear end side in the mounting direction is configured as the fixed portion 411. And In this case, the effect of attaching the replacement game nail more firmly is more reliably achieved. When the configuration (2) is adopted, the outer diameter of the fixing portion 411 in which the male screw 414 is formed is configured to be larger than the diameter of the enlarged diameter portion 412. In this case, the effect of attaching the replacement game nail more firmly is more reliably achieved. Note that, in the configuration of the above (1), the replacement game nail may have a longer formation section of the fixing portion 411 in the longitudinal direction than the game nail 401 before replacement, and the formation range of the fixing portion 411. Although the length of the fixing portion 411 is not changed, the entire section of the fixing portion 411 may be close to the front end portion of the main body portion 402.

  (I) In the above embodiment, the game nail 401 is disposed only in the vicinity of the entrance 151 of the warp flow path 152 and the entrance of the top winning opening 33a. However, the game nail 401 is disposed in other portions. It is good as well. Of course, all the board nails may be the game nails 401. When the game nail 401 is used only at predetermined points and the other board nails are general round nails, a portion where the game nails 401 are arranged is different from the other board nails. For this reason, for example, when a game ball passes in the game area, a point advantageous to the player (for example, when the game ball passes or rebounds, the game ball is guided to the top winning opening 33a. By placing the game nail 401 at an easy point), it is possible to easily follow the game ball at the point or to mark the stroke of the game ball to be shot into the game area. Note that the game nail 401 may be colored to ensure the above-described effects.

  Of the board nails erected on the front surface of the game board main body 30a, (1) "board nails with a relatively high collision frequency of game balls", (2) "shooting with adjustable force for launching game balls" It is desirable to use the game nail 401 as a “board nail on which a game ball hit relatively strongly by the device 60 can abut first”. For example, when the handle 18 is fully rotated and the game ball is fired most strongly, the game ball rebounds at the return rubber 54 (see FIG. 4) and vigorously collides with the nearby board nail. In the case of the arrangement configuration, the game nail 401 may be used as the board nail.

  (J) In the above embodiment, the board surface nail is erected on the front surface of the game board main body 30a and can directly come into contact with the game ball moving in the game area, but the other is arranged in the game area. It is also possible to apply to a game member. For example, the present invention can be applied to a nail for attaching an accessory such as a windmill to the game board main body 30a.

  More specifically, as shown in FIG. 14, a nail 961 for attaching the windmill 981 to the game board main body 30a is a cylindrical main body fixed in a state of being inserted in the front-rear direction with respect to the game board main body 30a. A portion 962, a columnar overhang portion 963 that extends forward from the front end portion of the main body portion 962 and protrudes into the game area, and a nail head 964 that is provided at the front end portion of the overhang portion 963 and has a larger diameter than the overhang portion 963. And.

  The main body 462 is fixed to the game board main body 30a in a state of being embedded in the game board main body 30a. The main body 462 extends forward from the front end of the fixed part 971, and has a larger diameter than the overhang 963. Part 972. The diameter of the fixed portion 971 is slightly larger than the inner diameter of the lower hole 431 formed in the game board main body 30a. In addition, the front end portion of the fixed portion 971 and the front end portion of the diameter-expanded portion 972 are configured in a tapered shape with a diameter reduced toward the overhang portion 963.

  The wind turbine 981 has a substantially disk shape, a front wall portion 982 having a communication hole 982a formed in the center, and a cylindrical shaft portion 983 extending rearward from the peripheral edge portion of the communication hole 982a of the front wall portion 982. And a plurality of (for example, three) wings 984 extending radially from the outer peripheral surface of the shaft portion 983. Further, the front and rear width of the wind turbine 981 is shorter than the length of the overhang portion 963 of the nail 961. Furthermore, the inner diameter of the communication hole 982 a is configured to be smaller than the diameter of the nail head 964.

  The nail 961 is inserted into the windmill 981 from the front wall portion 982 side to the communication hole 982a and the inner peripheral side of the shaft portion 983, and then the game board main body 30a is inserted into the lower hole 431 formed in the game board main body 30a. The main body portion 962 of the nail 961 is press-fitted from the front side. Accordingly, the windmill 981 is rotatably attached to the game board main body 30a.

  The gaming member is not limited to a nail-like (rod-like) shape. For example, the gaming member is fitted and fixed in a slit formed on the front surface of the game board main body 30a, and guides the game ball fired from the launching device 60 to the game area. It is also possible to apply to the rail 50 or the like. Further, the gaming members are not limited to those fixed to the game board main body 30a, and any gaming members may be used as long as at least a part protrudes into the gaming area and has a fixing portion fixed to the attached portion. That is, the present invention can be applied to the front frame set 14 provided on the front side of the game board 30 and the one fixed to the inner frame 12 to which the game board 30 is fixed (for example, the rail 50 is used as the front frame set 14). May be fixed).

  (K) In the above embodiment, the distance between the front end portion of the game nail 401 and the glass unit 137 is smaller than the radius of the game ball, so that the game nail 401 (fixed portion 411) and the game board main body 30a are connected. If the distance between the front end of the game nail 401 and the glass unit 137 exceeds the radius of the game ball, the game nail 401 and the game board main body 30a cannot be fixed (fixed at all) The range of formation of the fixing portion 411 may be set so that it cannot tilt, or when the game ball collides, the tilt is greatly inclined. In this case, the protruding length of the game nail 401 can be shortened to more reliably prevent an illegal act such as making it easier to enter the game ball into the top winning opening 33a or the warp channel 152 (right away with the visual inspection). In addition, by securely attaching the game nail 401, it is possible to prevent the game ball from being caught between the front end portion of the game nail 401 and the glass unit 137.

  (L) You may implement as a pachinko machine of a different type 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.

[Appendix]
The technical idea that can be grasped from the above embodiment will be described below.

  One type of gaming machine is a pachinko machine. Such a pachinko machine includes a plate-like game board main body constituting a game board and a glass plate provided in front of the game board main body, and a large space between the game board main body and the glass plate. The portion is a game area where a game ball fired by a predetermined launching means is guided. In addition, a large number of nails (board nails) projecting into the game area are arranged on the front surface of the game board main body, whereby the movement paths of the game balls moving in the game area are appropriately dispersed (for example, JP, A (See 2003-154110).

  However, for example, due to repeated collision of game balls against the board nails, the board nails may be unnecessarily deformed or broken. In this way, if the game nail is deformed or broken, not only the appearance quality is deteriorated, but also the movement path of the game ball is greatly changed. There is a risk that the game hall side will suffer a great disadvantage.

  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 including a board nail with improved durability.

Means 1. A game board main body that forms a game area on the front side where a game ball launched by the launching means is guided;
A game nail erected on the front surface of the game board main body (arranged in the game area),
The game nail is
A rod-shaped main body that is a portion that does not come into contact with a game ball moving in the game area;
An extended portion that extends from the main body and at least a tip protrudes into the game area;
The main body portion includes a fixed portion that is fixed to the game board main body in a state of being embedded in the game board main body, and includes a diameter-expanding portion that has a larger diameter than the overhang portion,
The gaming machine, wherein the overhanging portion extends from the enlarged diameter portion.

  For example, when an external force is applied to the overhanging part due to a game ball colliding or the like, a relatively large stress is likely to act near the base part of the overhanging part. On the other hand, according to the means 1, the overhanging portion extends from the enlarged diameter portion having a larger diameter than the overhanging portion. In other words, the diameter in the vicinity of the root portion of the overhang portion is relatively large. For this reason, the situation where a game nail fractures | ruptures near the base part of an overhang | projection part, or deform | transforms unnecessarily can be suppressed. Therefore, the durability of the game nail can be improved, and as a result, a gaming machine (game board) that can withstand long-term use can be obtained.

  In addition, since the entire game nail is not thickened, but at least a part of the main body is thickened, the space for moving the game ball moving in the game area is reduced due to the thickened overhang. Can be avoided.

  In addition, when an overhang | projection part extends from a fixing | fixed part, a fixing | fixed part comprises an enlarged diameter part and the diameter of a fixing | fixed part is comprised larger than the diameter of an overhanging part. Further, when the fixing portion is configured to be thick as described above, the contact area with the game board main body is increased, so that the mounting state can be stabilized.

  In addition, “the main body portion and the overhang portion have a circular cross section perpendicular to the longitudinal direction thereof, and the central axis of the main body portion and the central axis of the overhang portion are arranged on the same straight line. It is good also as. In this case, it is possible to prevent a situation in which the distance between the game nail and the predetermined object changes depending on the mounting direction of the game nail.

  Mean 2. The boundary part of the said main-body part and the said overhang | projection part is located in substantially the same position as the front surface of the said game board main body in the front-back direction, or ahead of the front surface of the said game board main body, The means 1 characterized by the above-mentioned. Game machines.

  For example, if a game nail is tilted and attached due to a manufacturing error, or a game nail or an accessory placed in a game area is misplaced, the game is played by hitting the overhanging portion. In some cases, the nail is intentionally bent to adjust the protruding angle of the game nail (the moving path of the game ball). At this time, for example, if the boundary portion between the main body portion and the overhanging portion is located at a position where it is greatly immersed from the front surface of the game board main body, the overhanging portion of the game nail that is bent by the adjustment contacts the peripheral edge of the opening of the nail hole. There is concern. In particular, when the strength of the game board main body is high, even if it is intended to bend the overhanging portion around its base portion, the overhanging portion bends at a portion that is in contact with the peripheral edge of the nail hole, There exists a possibility that the effect of the said means 1 may not be played well. In addition, when the strength of the game board is low, the peripheral edge of the opening of the nail hole is damaged (nail) due to the game nail (overhanging part) bent during the adjustment being pressed against the peripheral edge of the opening of the nail hole. There is a risk that the hole will expand or crack.

  On the other hand, according to the present means 2, the boundary portion between the main body portion and the overhanging portion is located at substantially the same position as the front surface of the game board main body or in front of the front surface of the game board main body in the front-back direction. For this reason, at the time of the adjustment, the game nail can be reliably bent around the boundary portion between the enlarged diameter portion and the overhang portion (near the root portion of the overhang portion). As a result, the effect of the means 1 is reliably achieved. Further, in the adjustment, the game nail is basically bent in front of the game board main body, so that it is possible to prevent the game board main body from being damaged by the bent game nail.

  Means 3. The gaming machine according to means 1 or 2, wherein a boundary portion of the diameter-expanded portion with the projecting portion is configured in a tapered shape with a diameter decreasing toward the projecting portion.

  According to the means 3, it is possible to disperse the stress acting near the boundary portion between the overhang portion and the enlarged diameter portion (near the base portion of the overhang portion), and the stress concentrates on the portion so that the game nail is The situation where it breaks can be prevented more reliably.

  Means 4. The enlarged-diameter portion is configured to be able to contact the game board body when an external force is applied to at least the overhang portion and the game nail is bent (when deformation occurs within an elastic limit). A gaming machine according to any one of means 1 to 3, characterized in that:

  According to the means 4, when the game nail is bent, the enlarged diameter portion is supported by being in contact with the game board main body, so that the deformation of the enlarged diameter portion is limited. For this reason, when the game nail is bent, it is possible to prevent a situation in which a relatively large stress acts on the fixed portion (the fixed portion is deformed relatively large), and as a result, the attached state Can be stabilized. It should be noted that the enlarged diameter portion may be substantially in contact with the game board main body by setting the game nail to the game board main body. In this case, the above-described effects can be achieved more reliably.

  Means 5. The game nail is attached to the game board main body by being inserted from a rear side of the game board main body into a pre-formed through hole formed in the game board main body in the front-rear direction. 4. The gaming machine according to any one of 4.

  According to the means 5, the game nail is inserted through the pilot hole and attached from the rear side of the game board main body. Therefore, the game nail mounting work is mainly performed on the rear side of the game board main body, so that the risk of the front surface of the game board main body being damaged at the time of the mounting work or the like can be suppressed. Quality degradation can be prevented.

  Furthermore, since it is not necessary to apply a force directly to the overhanging portion when attaching the game nail, it is possible to prevent the overhanging portion from being deformed, and various problems caused by this can be avoided. Further, since the prepared hole is formed in the game board main body, the game nail can be attached to the game board main body relatively easily, and the workability can be improved. Further, it is possible to suppress the possibility that the game board main body (particularly the front face) is deformed or cracked due to forcibly driving or screwing the game 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 game nail can be attached to the game board main body without making the game nail tip shape pointed, the design restrictions on the shape of the game nail tip exposed to the front of the game board main body are eased. be able to. In addition, in the case of a structure in which the game nail is screwed to the game board main body, it is not necessary to form a tool engaging portion such as a cross hole at the front end portion of the game nail, and it is possible to prevent deterioration of the appearance quality. it can.

  In addition, it is good also as "the said enlarged diameter part is smaller than the said lower hole into which the said game screw is penetrated, or is the same." In this case, when the game nail is bent, it is possible to prevent a situation in which a relatively large stress is applied to the fixed portion (the fixed portion is deformed relatively large). Can be further stabilized.

  Means 6. The front side of the main body portion embedded in the game board main body is the enlarged diameter portion that is not fixed to the game board main body, and the fixing portion fixed to the game board main body is the rear of the main body portion. The gaming machine according to any one of means 1 to 5, wherein the gaming machine exists only on the side.

  For example, if the projecting length of a game nail (projecting part) projecting forward from the front surface of the game board body becomes too short, the head (projecting part having a larger diameter than the general part of the projecting part) is formed at the front end of the projecting part. There is a concern that the game balls that should not be played by the game nails will not be played. Further, when the head is present at the front end portion of the overhanging portion, there is a concern that a game ball that should not be bounced by the game nail is bounced. In particular, when game nails are arranged corresponding to the entrances of various winning holes, it greatly affects the winning conditions of the game balls to the winning holes, resulting in a disadvantage for the player or the gaming hall. There is a risk that.

  On the other hand, according to this means 6, the front side of the main body portion embedded in the game board main body is an enlarged diameter portion that is not fixed to the game board main body, and the fixed portion fixed to the game board main body is It exists only on the back side of the main body. For this reason, unless the overhanging portion protrudes to a certain extent in the game area, the fixing portion cannot be fixed to the game board main body. Therefore, by fixing the game nail to the game board main body, the protruding length of the overhanging portion is inevitably secured to some extent, and the situation where the protruding length of the overhanging portion becomes too short as described above can be prevented. .

  Mean 7 The gaming machine according to any one of means 1 to 6, wherein a male screw is formed on an outer peripheral surface of the fixed portion.

  According to the means 7, the mounting state of the game nail can be further stabilized.

  Means 8. 8. The gaming machine according to claim 7, wherein the enlarged-diameter portion is formed so as to protrude forward from the front end portion of the fixed portion, and an external thread is not formed on the outer peripheral surface thereof.

  According to the means 8, there is an enlarged diameter portion where no external thread is formed between the fixed portion and the overhang portion. For this reason, for example, when the overhanging portion extends from the fixing portion where the male screw is formed, when an external force is applied to the overhanging portion, stress is concentrated on the valley portion of the fixing portion. Such a situation can be suppressed. As a result, it is possible to suppress a situation in which the game nail is broken at the valley portion of the fixed portion. In particular, as described in the above means 4, at least when the game nail is bent, the enlarged-diameter portion can be brought into contact with the game board main body, and when the external force is applied to the overhang portion, the fixed portion It is possible to more reliably suppress a situation in which stress acts on the film, and the above-described effects can be more reliably exhibited.

  Means 9. The gaming machine according to claim 7 or 8, wherein a diameter of a valley portion of the fixed portion where the male screw is formed is configured to be larger than a diameter of the overhang portion.

  According to the means 9, it is possible to suppress a situation in which the game nail is broken at the valley portion of the fixed portion.

Means 10. The game nail is configured to be held in pressure contact with an inner peripheral surface of the lower hole by being press-fitted into a lower hole formed in the game board main body,

The effect of being attached to the door is more reliably exhibited. In the case where a male screw is formed on the outer peripheral surface of the fixed part, the “outer diameter of the fixed part” means the diameter of the crest of the male screw.

Means 15. A game area where game balls launched by the launching means are guided; and
A gaming member disposed in the gaming area,
The gaming member is
A main body that is a part that does not come into contact with a game ball moving in the game area;
An extended portion that extends from the main body and at least a tip protrudes into the game area;
The main body portion includes a fixed portion that is fixed to the attached portion in an embedded state in the attached portion, and includes a thick portion that is thicker than the overhang portion,
The gaming machine, wherein the overhanging part extends from the thick part.

  For example, when an external force is applied to the overhanging part due to a game ball colliding directly or indirectly, a relatively large stress is likely to act near the base part of the overhanging part. On the other hand, according to the means 15, the overhanging part extends from a thick part thicker than the overhanging part. In other words, the diameter in the vicinity of the root portion of the overhang portion is relatively large. For this reason, it is possible to suppress a situation in which the gaming member is broken or unnecessarily deformed near the base portion of the overhang portion. Therefore, the durability of the gaming member can be improved, and as a result, a gaming machine that can withstand long-term use can be obtained.

  In addition, since the entire gaming member is not thickened, but at least a part of the main body is thickened, the space for moving the game ball moving in the gaming area is reduced due to the thickened overhanging portion. Can be avoided.

  The game member includes a board nail, a nail for fixing an accessory such as a windmill to the game board, and a part (an overhanging portion) protruding to the game area and fixed to the game board main body. . Further, the game member is not limited to a rod-like (nail-like) shape, and for example, a game ball that is fitted and fixed in a slit formed on the front surface of the game board main body and is launched by a launching device to the game area. It is also possible to apply to a guide rail or the like. Furthermore, the gaming member is not limited to one that is fixed to the game board main body, and may be any member that has at least a part protruding into the gaming area and having a fixing part fixed to the attached part. In other words, it can be applied to door members (front frame set) provided on the front side of the game board and those fixed to the inner frame to which the game board is fixed (for example, the rail is fixed to the front frame set). You may).
