Description

  The present invention relates to a gaming machine, and more particularly, to a gaming machine that enables replacement and recovery of a broken nail when a nail implanted in a gaming board is broken.

  Conventionally, it has been pointed out that nails implanted in game boards may break. In such a case, since it is necessary to replace the broken nail, a broken nail collection box is installed at the lower front side of the game board, and the change in the weight of the broken nail collection box is detected to confirm that the nail has broken. A technique for informing is proposed (Patent Document 1: JP 2007-319193 A). However, Patent Document 1 does not specifically describe a method for replacing a broken nail.

  On the other hand, a technology (Patent Document 2: Japanese Patent Application Laid-Open No. 2011-217888) for fixing a nail fixing piece to which a life nail is fixed to a unit base by an attaching / detaching mechanism, or a pilot hole for planting a game nail is provided on the game board. A technology that allows the printed sheet on the main body and the back side to penetrate, confirms the position of the pilot hole where the tip of the game nail remains from the back, and knocks the tip of the remaining game nail from the pilot hole using a tool (patent) There are proposals such as Literature 3: JP 2011-83385), and a nailing assisting tool (Patent Literature 4: JP 10-80533) for driving a new obstacle nail from the front of the game board.

JP 2007-319193 (Abstract, FIGS. 8 and 18) JP2011-217988 (abstract, FIGS. 4 to 10) JP2011-83385 (Abstract, 0007, FIG. 7) JP 10-80533 (abstract, FIGS. 5 and 6)

  Patent Document 2 has a problem that it is necessary to disassemble the game board in order to remove the fixed piece for replacement and newly install it, and to complicate the structure of the game board. Patent Document 3 also requires work such as removing the back unit case in order to work from the back of the game board main body. In Patent Document 4, as a result of driving a new nail from the front of the game board, the nail that has not been broken spills into the back unit case, which may cause problems such as a clogged ball or an electric system. In addition, the location of the nail pieces struck on the back side of the game board may become unclear, making it impossible to collect the game machine when it is dismantled, or the operator may be injured.

  Therefore, the present invention is designed so that when a nail is broken, the remaining nail fragments can be reliably recovered when a new nail is driven from the front side of the game board and replaced without disassembling the game board. The purpose is to.

A gaming machine of the present invention made to achieve such an object includes a gaming board in which a large number of nails such as obstacle nails and windmill fixing nails are implanted, and a back unit attached to the back side of the gaming board. The following configuration is provided.
(1) A nail that is pulled out from the driving position to the back of the game board at a position on the back side of the game board corresponding to the driving position of the nail with respect to at least a predetermined nail among the plurality of nails. A nail collection mechanism was provided to collect the fragments.

  Examples of the predetermined nail include a nail on the upper left side of the game area called “bump”, a nail on the upper right side of the game area of the game machine that hits “right-handed”, and the vicinity of the winning entrance called “life nail” The nails can be raised. These nails have a high frequency of game balls colliding and are empirically likely to break. According to the gaming machine of the present invention, since it is empirically associated with a nail driving position that has a high possibility of breakage and a nail collecting mechanism is provided on the back side of the game board, the broken pieces of the nail, When a bar-shaped tool and a hammer are used to drive the game board from the front side to the back side, and then pull it back to the game board, the nail fragments are collected by the nail recovery mechanism and located in the back unit. It will not be unknown.

Here, the gaming machine of the present invention may further include the following configuration.
(2) The nail collection mechanism is constituted by a closed body that closes at least the front surface, and is installed so that the front end is in contact with the back surface of the game board.

  As this closed body, for example, not only can it be constituted by a box body, a cylinder body, a bag body, etc., which are open on the front surface, but the front surface can also be closed so that it can be broken by a nail fragment. Absent. Moreover, you may be comprised with the block body which can drive in the front-end | tip of a nail like a polystyrene block. This is because such a block body can also be a closed body that closes at least the front surface. The gaming machine of the present invention is also provided with the configuration (2), so that the nail fragments that have been pulled out to the back side of the game board can be reliably accommodated in the nail collecting mechanism. As a result, it is possible to reliably prevent the nail fragments from falling to the surroundings.

In addition, these gaming machines of the present invention may further include the following configuration.
(3) The nail recovery mechanism includes a backflow prevention mechanism that keeps the nail fragments contained therein.

  As a backflow prevention mechanism, for example, a backflow prevention valve or protrusion is installed at the entrance of the closing body, or the entrance of the closing body is closed with a rubber stopper, rubber film, vinyl sheet, etc. However, it is possible to use a configuration that includes a device that obstructs the exit of the nail once it enters the closure body. Moreover, the structure which hold | maintains the fragment | piece of the nail which installed the adhesive body in the inside of a closure body, was filled with the adhesive, and was accommodated with adhesive force can also be mention | raise | lifted. Furthermore, when the game board is formed of a light-transmitting synthetic resin, a cell sheet is pasted on the back of the game board so as to close the pilot hole of the nail, and this cell sheet also serves as the above rubber film or the like. By doing so, a backflow prevention mechanism may be realized. Further, the backflow prevention mechanism may be embodied by a configuration in which the block body is made of rubber and nail fragments are sandwiched from the periphery. The gaming machine of the present invention is provided with such a “(3) backflow prevention mechanism”, whereby the nail fragments once accommodated can be held in the nail collecting mechanism, and foreign matter is generated during the disassembling work of the gaming machine. The effect to prevent is also demonstrated.

In addition, these gaming machines of the present invention may further include the following configuration.
(4) The nail collecting mechanism is provided at a predetermined position of a unit part to be attached so that the front end is brought into contact with the back side of the game board.

  In this case, “(4A) the unit part is a back unit” and “(4B) the nail collecting mechanism is integrally formed at a predetermined position of the back unit” are also included. It is good to have.

  The back unit is attached with the front end in contact with the back of the game board so as to form a closed space for accommodating movable bodies and electronic parts on the back side of the game board. The back of the nail is covered with this back unit. Therefore, by forming the nail recovery mechanism integrally with the back unit, the operation of installing the nail recovery mechanism on the back side of the nail, which is empirically likely to break, is carried out by the back unit mounting operation. In addition, since the nail collecting mechanism is provided, an effect that the number of assembling steps is not increased is exhibited. Further, it is possible to easily realize the nail collecting mechanism as a closed body by integral molding, and it is also possible to easily realize the contact of the front end of the closed body with the back surface of the game board.

In addition, these gaming machines of the present invention may further include the following configuration.
(5) The game board is provided with pilot holes for planting the plurality of nails.
(6) The pilot hole is a through hole penetrating from the front surface to the back surface of the game board, and the nail collecting mechanism is configured as a hole continuous with the through hole.

  By providing the pilot hole, alignment when a new nail is driven can be performed accurately. The pilot hole is a through hole and the nail recovery mechanism is a hole continuous to the through hole, so that the nail fragments can be smoothly pulled out and the direction of the pull out can be accurately guided to the nail recovery mechanism. Nail fragments can be reliably recovered.

  In particular, it is preferable to adopt a configuration of “(6A) the hole as the nail collection mechanism has a size for holding the shaft portion of the nail from the periphery”. By adopting such a configuration as well, the nail fragments that have come out rearward from the pilot hole are driven into the holes of the nail collection mechanism, and are held simultaneously with the collection, thereby preventing backflow.

  The present invention is of course effective for gaming machines that employ veneer gaming boards, but is particularly effective for gaming machines that employ synthetic resin gaming boards. This is because the game board made of synthetic resin has a high stress generated at the base of the nail because of its hardness, and the problem of breakage is likely to occur compared to the veneer. Also, instead of providing the nail collection mechanism by integral molding with the back unit, it may be configured as a separate unit attached to the back unit, or as a perforated part attached so as to extend the pilot hole to the back of the game board, As described above, rubber or styrene foam may be used, as well as metal parts.

  According to the present invention, when a nail is broken, when a new nail is driven from the front side of the game board and replaced without disassembling the game board, the remaining nail fragments can be reliably recovered. Can be. As a result, it is possible to prevent short-circuiting, clogging, injury due to the tip of the nail, and the like caused by such loss of nail fragments.

For example, the vertical and horizontal dimensions are set so that the nail pieces 11b can be easily received, and the depth is set to a depth at which the nail pieces 11b can be accommodated. The depth of the nail piece 11b that can be received is the same as the length of the pilot hole 24, that is, the thickness of the plate member 20 or more, but it is certain that the depth is larger. May be accommodated in a state of being stuck in the back of the square hole 34. The vertical and horizontal dimensions that can easily accept the nail fragments 11b can be designed to be equal to or larger than the diameter of the nail. On the other hand, there may be a design that is slightly smaller than the diameter of the nail. When the vertical and horizontal dimensions are slightly smaller than the diameter of the nail, the nail pieces 11b are sandwiched and held by the inner wall surface of the square hole 34 from the top, bottom, left and right, and the backflow prevention is performed simultaneously with the storage of the nail pieces 11b. Is demonstrated. Therefore, in the present embodiment, the following description will be given on the case where the vertical and horizontal dimensions of the square hole 34 are slightly smaller than the diameter of the nail.

  Thereafter, a new nail 11c is driven into the plunge pilot hole 24 from which the nail fragments 11b have been removed. The new nail 11c may be driven in at the same time and the nail fragments 11b may be pushed out of the lower hole 24 and stored and held in the square hole 34 of the rectangular tubular portion 35.

  According to the present embodiment, the square hole 34 is provided in a straight line with the drop-in hole 24 of the drop-in nail 15 and the front end is in contact with the back surface of the plate member 20. Since the vertical and horizontal dimensions are slightly smaller than the diameter of the nail and the depth depth is equal to or greater than the plate thickness of the plate member 20, the nail fragments 11 b remaining in the pitting lower hole 24 when the piling nail 11 a is broken. Is pulled out to the back side of the plate member 20, the nail fragments 11 b are completely stored in the square hole 34 of the rectangular tube-shaped portion 35, and are sandwiched from the top, bottom, left and right by the inner wall surface of the square hole 34. Attached and held. As a result, a new nail 13c can be attached and the broken nail fragments 11b do not become unknown in the back unit.
