Description

  The present invention relates to a gaming machine that is installed and used in a game hall such as a pachinko parlor.

  Pachinko machines, which are game machines that are installed and used in pachinko parlors and other game halls, give a certain value to pachinko balls, which are game media, and exchange pachinko balls acquired through games for various prizes. can do. The pachinko machine is equipped with various control devices that operate based on the supply of pachinko balls on the back of the game board and the main body base on which the game board is mounted, and a control circuit device corresponding to control these drive devices. When a player plays a game, these are appropriately operated to make the game full of fun.

  A control circuit device arranged in a recent pachinko machine is generally one in which a CPU (central processing unit) provided on a substrate performs electronic control according to a control program. The control program is stored as data in an IC chip mounted on a substrate such as a mask ROM (read only memory), and the CPU sequentially reads and executes the control program data from the IC chip according to the gaming state. Control is done by doing.

  By the way, when replacing a pachinko machine at a game hall, it is common to remove and replace the entire main body base including the mounting frame. However, the parts that make up a pachinko machine include those that can be reused as they are, which is a major cause of cost increase when changing models. For this reason, it is currently under consideration to replace the parts that can be diverted in the game arcade and replace only the parts that will be newly changed. In this case, the base of the main body, a pachinko ball launching device and a payout device that perform basic operations at the time of gaming, a lamp and a speaker that performs a production effect are deferred in the game hall, and a game board, a variable symbol display device, a control circuit device, etc. It is generally considered to replace the game board unit that has been changed. For this reason, the game board unit can be attached to and detached from the main body base.

  However, since the game board unit is detachable from the base of the main body, the game board unit may be illegally removed and replaced with an illegal game board unit in which various winning holes, winning ball devices, obstacle nails, etc. are modified. In addition, since the control circuit device is exposed when the game board unit is removed, the game board unit is illegally removed, and the control program of the control circuit device attached to the inside of the main body base or the back of the game board unit is illegally altered. There was a problem that.

  At present, as a method for solving this problem, for example, a method of joining the main body base and the game board unit by a connecting member (wedge member) formed in a wedge shape is being studied. According to this method, when the connection between the main body base and the game board unit is released, the connecting member can be destroyed and the connecting member cannot be reused. As a result, illegal acts such as illegally removing the game board unit and illegally crafting the control circuit device can be prevented.

  However, if the connecting member is destroyed when repairing or performing maintenance work on the control circuit device incorporated in the main body base or the game board unit, a new connecting member must be prepared each time, resulting in an increase in cost. Problems arise. Further, when the game board unit is illegally removed by destroying the connecting member and the game board unit and the main body base are joined again by the forged connection member, it is identified whether or not the game board unit has been illegally removed. The problem of being unable to do so occurs. Further, when the connecting member as described above is used, there arises a problem that the number of repairs or maintenance work cannot be identified.

  The present invention has been made to solve the above-described problems, and can reliably prevent unauthorized removal of the game board unit, and can easily check the number of times the game board unit has been removed. An object is to provide a game machine that can be used.

In order to achieve the above object, a gaming machine according to the present invention includes a gaming board having a gaming area, and a structure detachably provided on the gaming board on the gaming area side of the gaming board.

When inserted into the hole, the hole cannot be removed. A plurality of sealing portions to be locked to the hole portions are provided, and one end is fixed to the peripheral surface of the shaft portion serving as the rotation center of the wedge member, and the other end is A string that is fixed to one of the sealing portions, and that prevents the wedge member from rotating by the predetermined amount when the sealing portion is locked in the hole portion in a non-removable state. A plurality of movement prohibiting members are provided so as to correspond to the respective sealing portions.

  According to a second aspect of the present invention, each of the holes is formed at a position where the distance from the axis of the wedge member is different from each other, and the lengths of the rotation prohibiting members are different from each other.

  According to the gaming machine of the present invention, when the gaming board unit is attached to the main body base, a predetermined rotation prohibiting member is selected from a plurality of rotation prohibiting members, and the holes corresponding to the rotation prohibiting members are selected. When the sealing part is inserted into the part and the game board unit is removed from the base of the main body, the rotation prohibiting member is destroyed, and then the locking between the wedge member and the locking part is released to remove the game board from the base of the main body. Since it did in this way, it can confirm easily and reliably that the game board unit was removed from the main body base by the trace by which the rotation prohibition member was destroyed. Thereby, unauthorized removal of the game board unit can be prevented. In addition, the number of times that the game board unit has been removed from the base of the main body can be confirmed from the sealing portion inserted into the hole, and thus the number of repairs and maintenance operations can be easily known. Furthermore, it is possible to easily identify whether or not the game board unit has been illegally removed by checking whether or not the predetermined sealing portion is inserted into the predetermined hole. Therefore, unauthorized removal of the game board unit can be prevented.

It is formed in a shape that is elastically deformed so that the diameter of the tube increases.

  The operation of the pachinko machine 2 configured as described above will be described. In assembling the game board unit 16, first, the game board 4 and the support 18 are integrated by fastening with screws. Next, the locking knob 24 of the guide rail frame locking member 22 provided on the support 18 is sequentially inserted into the locking member insertion hole 4 c of the game board 4 and the knob locking hole 25 c of the guide rail frame 19. As shown in FIG. 9, the wedge member 30 provided in the guide rail frame 19 is sequentially inserted into the wedge member insertion hole 4 d of the game board 4 and the insertion hole 18 c of the support 18. To be inserted. And the game board 4, the support body 18, and the guide rail frame 19 are integrated by rotating the latching knob 24 exposed from the knob exposure opening 28b.

  When the game board unit 16 assembled in this way is attached to the main body base 6, first, the locking portion 17a of the game board unit locking member 17 is set at the mounting position (see FIG. 4). Then, the locking member 17a is inserted into the locking member locking hole 4b from the back surface 16a side of the game board unit 16 and protrudes to the game area 4a side, and the wedge member protrudes from the back surface 16a side of the game board unit 16 30 is inserted into the key cylinder 53. As shown in FIG. 10, when the engaging portion 33 is inserted into the main body portion 54 of the key cylinder 53, the engaging portion 33 is locked to the locking claw 54b, and the wedge member 30 is in a direction opposite to the insertion direction. It becomes impossible to remove. When the locking portion 17a is rotated and set at the holding position (see FIG. 5), the locking portion 17a engages with the locking member locking hole 4b and is inserted from the locking member locking hole 4b. It becomes impossible to remove, and the game board unit 16 is fixed to the main body base 4.

  After the game board unit 16 is attached to the main body base 6 in this way, the sealing portion 47 of the sealing member 41 is fitted into the hole 48. When the sealing portion 47 is fitted into the hole portion 48, the locking claw 47b of the sealing portion 47 is locked to the edge of the insertion port 48a on the accommodating portion 48b side in a non-removable state in the direction opposite to the insertion direction. To do. As a result, the rotation amount of the wedge member 30 is limited to less than 90 degrees by the rotation prohibiting member 36, so that the wedge member 30 cannot rotate 90 degrees or more. That is, the wedge member 30 cannot be moved from the unremovable state to the removable state. Thereby, unauthorized removal of the game board unit 16 can be prevented.

  When removing the game board unit 16 from the main body base 3, first, the rotation prohibiting member 36 is cut using a cutting tool such as a nipper. Next, the operation knob portion 35 of the wedge member 30 is picked and the wedge member 30 is rotated by 90 degrees to release the engagement between the engagement portion 33 and the engagement claw 54b. Then, the game board unit 16 is removed from the main body base 3 by pulling out the engaging portion 33 of the wedge member 30 from the key cylinder 53. As a result, even if the rotation prohibiting member 36 is cut and the gaming board unit 16 is illegally removed, a trace of cutting the rotation prohibiting member 36 remains, so the gaming board unit 16 is illegally removed. This can be easily confirmed.

  When the game board unit 16 is attached to the main body base 3 again, the sealing board 42 is inserted into the hole 49 after the game board unit 16 is attached to the main body base 3 according to the procedure described above. When removing the game board unit 16 from the main body base 3 again, the game board unit 16 is removed from the main body base 3 in the above-described procedure after the rotation prohibiting member 37 is cut. Thereafter, each time the game board unit 16 is attached to the main body base 3, the sealing members 43 to 45 are sequentially inserted into the holes 50 to 52, and the game board unit 16 is removed from the main body base 3 every time. The movement prohibiting members 38 to 40 are sequentially cut.

  Thereby, it is possible to easily confirm the number of times that the game board unit 16 has been removed from the main body base 3 only by visually observing which sealing member of the sealing members 41 to 45 is inserted into the hole. . Since the number is written on the lower surface 46c of the pedestal 46, the number of times that the game board unit 16 is removed from the main body base 3 can be known from the number. Further, if the sealing member that should be fitted into the hole is not fitted, or if the sealing member that should not be fitted into the hole is fitted, the gaming board unit 16 is illegally It can be easily recognized that it may have been removed. For example, if the sealing member 42 is fitted in the hole 49 even though the game board unit 16 has never been removed from the main body base 3 in the past due to repair or maintenance, It can be recognized that the board unit 16 may have been removed illegally.
