Description

  The present invention relates to a gaming machine suitable for preventing fraud, and more particularly to a gaming machine that prevents unauthorized opening of a front door that closes an opening of a casing of the gaming machine.

  One type of gaming machine is a spinning machine, for example, a slot machine. The slot machine includes a plurality of reels as rotating bodies with a plurality of symbols attached thereto, and each reel starts rotating when a player inserts a medal and operates a start lever. After each reel starts rotating, each reel is sequentially stopped by operating a stop button or elapse of a predetermined time.

  In the slot machine, a lottery is performed on condition that a medal (or coin) is inserted and a start lever is operated, and the lottery result is a win, and a player is placed on a preset active line. A predetermined number of medals are paid out on condition that the winning symbol is stopped, or a special game state (such as a bonus game) advantageous to the player occurs.

  In addition, such a slot machine includes a box-shaped housing having an opening on the front side, and a front door attached to the front side of the housing so as to be openable and closable. It is arranged and used for games with the front door covering the opening. In addition, a power supply device for supplying power to each part of the slot machine is provided inside the casing, and the slot machine is operated by the power supplied from the power supply device.

  By the way, in such a slot machine, a sub-control board that mainly performs control related to game effects, a spinning device board that controls the rotation of the reel, and operation signals from the bet button, start lever, and stop button are transferred. A central display substrate and a power supply device substrate that controls power supply to each drive unit and the like, and these substrates are centrally controlled by a main control substrate.

  The main control board also has a ROM (Read Only Memory) in which system programs, programs for slot machine games, and the like are written, and a CPU (Central Processing Unit) that reads out a predetermined program from the ROM and performs predetermined control. In addition, an electronic device such as a RAM (Random Access Memory) that holds the calculation results by the CPU is mounted, and the control by the above-described various substrates is instructed based on the program read from the ROM as the game progresses. It has become so.

  By the way, the above-described ROM mounted on the main control board is detachably attached to the connector on the board for periodic inspections and the like. In addition, each electronic element described above is sandwiched between the main body case and the upper cover case so as not to be tampered with illegally by a fraudulent jig such as a cell or wire inserted from the outside of the housing. It is a unit configuration. Further, the upper lid case is formed of a transparent plastic so that the state of each electronic element on the main control board can be easily confirmed by hall staff or the like. Further, the upper lid case is sealed with a seal that has been inspected by law and regulation, and the main body case and the upper lid case are caulked and joined via a connecting member that is joined in a caulking state, and the upper lid case is opened. There is no such thing.

  Also, the main control board is usually attached to the inner surface of the casing so as to be located above the spinning device having three reels with a predetermined number of symbols when the interior of the casing is viewed from the front. Yes. This is because, due to the configuration of the slot machine, the spinning device is arranged almost in the center of the housing, and a hopper device for paying out medals, a power supply device for supplying power, and the like are arranged below the spinning device. This is because the position where the state of the main control board can be easily confirmed by opening the front door is located above the rotating device.

  In addition, by attaching the main control board to the inner surface of the housing so as to be positioned above the rotating device, the position is the farthest when viewed from the front door side, and the main control board is located between the main body case and the upper lid case. By adopting a unit configuration sandwiched between them, various electronic elements on the main control board are not tampered with illegally by a fraudulent jig such as a cell or wire inserted from the outside to the inside of the housing. It is possible to take appropriate measures.

  By the way, in such a slot machine, the front door is locked by a locking device at a position where the opening of the housing is closed, and the hall staff or the like performs maintenance work including confirmation of the state of each electronic element on the main control board. When performing a ball management work or the like, the front door is opened by inserting a dedicated key into the keyhole of the front door and releasing the lock.

  That is, the front door is only locked at a position where the opening of the housing is closed by the locking device. Therefore, for example, when the slot machine with the above-described main control board mounted in the housing is transported to, for example, a hall or the like, the front door is opened illegally, for example, the ROM on the main control board is illegally programmed. It may be replaced with a rewritten so-called back ROM or illegal ROM. Furthermore, a substrate case in which an illegal control substrate is accommodated may be replaced with a currently used substrate case.

  This is because the main body case holding the main control board and the upper lid case are caulked and joined via a connecting member that is joined in a caulking state, so that the upper lid case cannot be opened. This is because the hole staff is formed of a transparent plastic so that the state of each electronic element on the main control board can be easily confirmed, and a hole is opened by heat of a soldering iron or the like.

  If the inspected ROM is replaced with a so-called back ROM or illegal ROM from the hole opened in the upper lid case, it can be replaced with what is called the back ROM or illegal ROM by checking the opened hole. The hole may be camouflaged to cover it with an improperly created counterfeit seal. If the camouflage is covered with such a counterfeit seal, you can immediately notice the camouflage if the hall staff, etc., familiar with the slot machine's internal configuration confirms it, but they are not familiar with the slot machine's internal configuration. When hall staff confirm, they may not be aware of the disguise.

  In this way, if the inspected ROM is illegally replaced with what is called the back ROM or illegal ROM, for example, the above-mentioned special gaming state (bonus game etc.) is forcibly generated halfway and illegal Invite people to pay out coins.

  Here, as a locking device of a gaming machine, for example, there is a gaming machine locking device as disclosed in Patent Document 1. This is composed of locking means provided near the center of the front door, and a stopper member that is arranged above and below the front door or the other side of the main body case and contacts the ground when the front door is closed to the main body case by the locking means. The locking means includes a striker fixed to the main body case, a latch that engages and locks the striker when closing the front door and the main body case, a key cylinder with a keyway on the front, and a key cylinder Consists of a pole that interlocks with one rotation to release the engagement between the latch and striker, and a case that covers the latch and the pole, and the slot machine cheating, that is, forcing from outside the key cylinder In this way, it is possible to prevent as much as possible from opening and / or direct unauthorized operation to the eaves member.

Therefore, even if the first and second locking claws 83 and 84 are pushed up, the engagement holding portion 52e and the engagement protrusion 62b are inserted into the engagement holding portion 52e of the front door side engagement portion 52 shown in FIG. Therefore, the upward movement is restricted, and the housing side engaging portion 62 is not pushed up.

  When the front door side engaging portion 52 and the housing side engaging portion 62 are overlapped, the positions of the first engaging claw portion 83 and the first engaging concave portion 52c coincide with each other. The positions of the second engagement claw portions 84, 84 and the second engagement concave portions 52d, 52d shown in FIG. The first engaging recess 52c and the second engaging recess 52d enter.

  As a result, the first and second engaging recesses 52c and 52d are engaged with the first and second engaging claws 83 and 84, and the engaging protrusion 62b and the engaging holding portion 52e are fitted. Then, the front door side engaging portion 52 and the housing side engaging portion 62 are engaged. If it will be in this state, even if it is going to open the front door 3, the engagement surface 83b of the 1st engagement nail | claw part 83 is engaging with the 1st engagement recessed part 52c (the 2nd engagement claw part 84 is also the same). Since the engagement surface 83b extends along the wall of the first engagement recess 52c (the same applies to the second engagement claw portion 84), the first and second engagement claw portions 83 and 84 are pushed upward. In addition, since the engagement protrusion 62b and the engagement holding portion 52e are fitted, the front door side engagement portion 52 cannot be separated from the housing side engagement portion 62. The first and second engaging claws 83 and 84 are not detached from the second engaging recesses 52c and 52d. Therefore, the front door side engaging portion 52 and the housing side engaging portion 62 are fixed, and the front door 3 can be coupled to the housing 2 side.

  On the other hand, as shown in FIG. 10, the stopper member 70 is inserted into the stopper insertion space of the housing side engaging portion 62 so that the first engaging claw portion 83 and the second engaging claw portion 84 (see FIG. 8) face upward. Since the above-described engagement by the first engagement claw portion 83 and the second engagement claw portion 84 does not occur when mounted on the 62a, the front door side engagement portion 52 and the housing side engagement portion that are not in the locked state. Each engagement with 62 is not performed.

  Here, by confirming characters such as “lock” on the surface 93 of the inner member 90 of the stopper member 70 from the hole 2c of the upper plate 2b of the casing 2 described above, the front door side engaging portion 52 and the casing side engagement are confirmed. It can be recognized that the joint portion 62 is engaged.

  In this state, for example, the slot machine 1 in which the above-described main control board 41 is mounted inside the housing 2 is transferred to, for example, a hole. When the front door 3 is opened illegally during transfer to a hole or the like or after transfer, the connecting portion 63 of the housing side engaging portion 62 is disconnected. In this case, since the disconnection of the connecting portion 63 of the housing side engaging portion 62 remains as a trace, the housing side engagement is made from the hole 2c of the upper plate 2b of the housing 2 during or after the transportation to the hole or the like. By confirming whether or not the connecting portion 63 of the joint portion 62 is disconnected, it can be easily confirmed whether or not the front door 3 has been opened illegally.

  On the other hand, when it is confirmed by confirmation of the connecting portion 63 of the housing side engaging portion 62 that the front door 3 is not opened illegally, for example, after each slot machine 1 is installed at a predetermined position in the hall, the housing By inserting a cutting tool such as a nipper into the hole 2c of the upper plate 2b of the body 2 and disconnecting the connecting portion 63 of the housing side engaging portion 62, the front door side engaging portion 52 and the housing side engaging portion 62 are engaged. Can be canceled.

  Thus, in this embodiment, for example, the front door side engaging portion 52 as the first engaging means is attached to the front door 3 side, and the housing side engaging portion as the second engaging means is attached to the housing 2 side. 62 is attached, and the front door side engaging portion 52 and the housing side engaging portion 62 are engaged according to the operation of closing the front door 3, and the confirmation and release of the engagement is formed on the housing 2 side, for example. This is done through the hole 2c.

  In this case, for example, the front door 3 can be opened by cutting the housing side engaging portion 62 through, for example, the hole 2c formed on the housing 2 side, but the front door 3 is illegally opened. In such a case, for example, the disconnection of the housing side engaging portion 62 is left as a trace of unauthorized opening. Thereby, it is possible to easily confirm from the trace that the front door 3 has been opened illegally, for example, during the transport of the slot machine 1 with the main control board 41 attached inside the housing 2.

  Specifically, for example, since the case-side engaging part 62 is provided with a severable connecting part 63 as a separating part connected to the mounting piece 51, when the connecting part 63 is illegally disconnected, It can be easily confirmed that the front door 3 has been opened illegally from the trace of the separation.
