Description

  The present invention relates to a gaming machine, and more specifically, a board storage box that is attached in a state in which a control board that performs control related to a game is stored on the back of a gaming board of a gaming machine such as a pachinko gaming machine or a throttle machine. The present invention relates to a fraud prevention mechanism in which a fraud prevention measure for preventing illegal opening of the substrate storage box is taken.

  In recent years, pachinko machines, throttle machines, and other gaming machines have become mainstream that control various prize-winning devices and symbol variation display devices, etc., provided on the game board to excite the fun of gaming. The winning device, the symbol variation device, and the like are controlled by a logic control circuit board provided with a large number of electronic components such as ICs and LSIs, or a control board equipped with a microcomputer. A control board for controlling the game content of such a gaming machine is generally stored in a board storage box attached to the back side of the game board.

  The structure for sealing the control board in the board storage box that has been used in the past is that the cover body and the case body are assembled with screws, and then a sealing seal is put on the joint between them. It was made of a transparent synthetic resin material such as acrylic so that the state of the control board housed inside could be seen from the outside so that fraudulent behavior could be confirmed. It was not effective against fraudsters who used various release agents.

  In order to prevent such actions, it may be possible to make the substrate storage box a structure that cannot be opened or extremely difficult to open, and to seal the box so that there is no other way to open the box. It is not realistic considering the maintainability such as ROM inspection and repair by the target organization.

  Therefore, once the seal is opened, a sealing member (special member) is provided by separately connecting the sealing portions provided integrally with the cover body and the case body so that the opened trace remains. It has been proposed to have a structure in which sealing and unsealing can be performed a plurality of times.

  At least one of the connecting portions between the cover body and the case body and the respective sealing portions is formed so as to be easily cut by a tool such as a nipper, and the connecting portions are fixed by cutting the connecting portions. It is structured so that it can be opened by separating the part that has been separated, and if it is opened easily, it can leave traces of its cutting, so it can handle fraud It is widely adopted because it is good.

  In addition, a plurality of sealing portions are provided so that sealing and opening can be performed a plurality of times in consideration of maintainability such as ROM inspection and repair by the above-described public organization. In this case, since the sealing member used for fixing the sealing parts cannot be used for re-sealing, the sealing part of the cover body, the sealing part of the case body, and the sealing member are made into one set. This is realized by providing a plurality of sealing locations. For example, if there are eight sealing locations, if two of them are used for sealing, a total of four times of sealing and unsealing can be performed.

  An example of such a substrate storage box will be described in detail with reference to the drawings. 17 is an external perspective view of the substrate storage box 200, FIG. 18 is an exploded perspective view thereof, FIG. 19 is a top view of the sealing portion, and FIG. 20 is an A- view of the sealing portion 201 provided on the side surface of the substrate storage box 200.

On the inner peripheral edge of the engagement hole 213a, an engagement piece 213b that engages with a concave engagement groove 211b provided around the distal end portion 211a of the insertion pin 211 is formed to protrude slightly diagonally downward. .

  Further, a plurality of (four in this example) pin insertion bases 215 are provided as cover side sealing portions 206 on the left and right outer side surfaces (only one side is shown in the drawing) of the cover body 202 attached to the case body 201. Are provided so as to be integrally aligned via a connecting portion 218 formed so as to be cuttable, and on both sides of the pin insertion base 215, the above-described pin fixing screw 213 is screwed and fixed to cover the tapping screw 207 from above. Screw concealment pieces 217 and 217 are provided.

  As shown in FIG. 21, insertion pins 211 are mounted in advance on the pin insertion bases 215, 215,. The insertion pin 211 is formed by cutting with a metal rod such as aluminum or integrally formed with a synthetic resin material, and includes a flange-shaped head portion 211e and a columnar body portion 211d. A knurled ring portion 211c having a diameter slightly larger than the outer diameter of the main body portion 211d is formed at an intermediate position of the cylindrical main body portion 211d, and the pin insertion base 215 is inserted in a state where the insertion pin 211 is loosely inserted. Can be inserted. Thereby, for example, it is not necessary for an administrator of a pachinko hall to store the insertion pin separately, and therefore, there is no risk of loss or theft, so handling is convenient.

  Further, the connecting portions 218, 218,... Connecting the pin insertion bases 215, 215,... And the side wall of the cover body 202 are formed in a shape that can be easily cut by a tool such as a nipper, By cutting the connecting portion 218 at the sealed portion of the connecting portions 218, 218,..., The pin insertion base 215 at the sealed portion can be separated from the cover body 202.

  The substrate storage box 200 having such a structure can seal and open the main control substrate 203 therein a plurality of times. As shown in FIG. 17, numbers are displayed on the left and right sides of the upper surface of the cover body 202 so as to be diagonal (in this case, 1 to 4). The two insertion pins 211 marked with are struck and sealed. In order to open the ROM of the main control board 203 for inspection, it can be opened by cutting the two connecting portions 218 with the left and right numbers “1” used for sealing.

  In order to seal again, the main control board 203 can be confined in the box again by striking the two insertion pins 211 with the left and right numbers “2”. Since the main control board 203 accommodated in this way can be opened and sealed for a valid reason such as ROM inspection and repair several times, maintenance is also good.
