Description

  The present invention relates to a gaming machine, and more particularly to a gaming machine configured so that a gaming board can be viewed from the front side through a transparent member disposed on the back side of a frame member.

  A pachinko machine, which is a typical gaming machine, is assembled to the outer frame fixed to the gaming machine stand so that the inner frame can be attached and detached and opened and closed, and the game board holding portion formed on the inner frame, A game board that defines a required game area is held. And, on the front side of the middle frame, a front frame (corresponding to the frame member of the present application) in which a window portion that opens back and forth at a position corresponding to the game board is pivotally supported so as to be opened and closed, The game area of the game board can be viewed from the front side of the pachinko machine through a glass unit attached to the back side of the front frame.

  The game board is provided with a frame-shaped decorative member (so-called center accessory) at a substantially central position of the game area, and a plurality of symbols are variably displayed through the opening of the decorative member. The symbol display device such as a liquid crystal type or a drum type that plays the symbol variation game is faced from the rear, and the pachinko ball (game ball) is changed by the winning of the pachinko ball (game ball) at the lower position of the decorative member on the game board. A start winning device for starting the game and a special winning device that opens at the time of a big hit are arranged. In such a pachinko machine, the pachinko ball launched into the game area gradually flows down due to its own weight while bouncing off by contact with a game nail or the like implanted in the game area, and starts in the process of flowing down the game area. By winning the winning device, various game effects such as a reach effect accompanying the symbol variation game are made on the symbol display device, and when the symbols stop on the symbol display device in a predetermined combination, a so-called big hit occurs. A special winning device provided on the game board is configured to be opened to obtain a large number of prize balls. In addition, the pachinko machine provided with such a structure is disclosed by patent document 1, for example.

JP 2001-224748 A

  As described above, a general pachinko machine is configured such that a predetermined game is performed in response to winning of a pachinko ball that flows irregularly in the game area. Here, the pachinko ball used in the pachinko machine is made of a metal ball having a diameter of about 1 cm, and the front side of the game board is covered with a glass unit. There is a risk that an illegal act of intentionally operating a pachinko ball in the game area will be performed. For this reason, the glass unit employed in a general pachinko machine is composed of two glass plates that are spaced apart by a predetermined distance in the front and rear, and the distance from the board surface of the game board to the front surface of the glass unit is increased. The influence of the magnet operated on the front side of the glass unit on the pachinko ball is reduced.

  However, even if the glass unit is composed of two glass plates as described above, the space between the game board and the front frame is limited due to the structure of the pachinko machine. There is a limit to increasing the size. For this reason, even if a glass unit consisting of two glass plates is adopted, it is difficult to prevent unauthorized operation of the pachinko ball when an illegal act is performed using a magnet that expresses a strong magnetic force. There is a strong demand for effective technology for preventing fraud.

  For this reason, some recent pachinko machines have been proposed in which a magnetic sensor is provided on the game board side to detect fraud using a magnet. However, since the magnetic detection range of one magnetic sensor is limited, it is necessary to dispose a considerable number of magnetic sensors (10 or more depending on the configuration of the game board) in order to detect a wide range of illegal acts. It is a factor that pushes up the manufacturing cost of pachinko machines. In addition, as described above, the game board is provided with the decorative member, various winning devices, and other effect devices, so that a large number of magnetic sensors required to detect fraud in the entire game area. It is extremely difficult to arrange the game board on the game board. Therefore, as a practical configuration, there are many cases where a magnetic sensor is intensively arranged by selecting a place where there is a possibility of an illegal act using a magnet. For this reason, when a fraudulent act is performed at a position outside the magnetic detection range by the magnetic sensor, the fraudulent act is not detected by the magnetic sensor, and there is a disadvantage that the fraudulent act cannot be prevented.

  In view of the above problems inherent in the conventional technology, the present invention has been proposed to suitably solve these problems, and a gaming machine capable of improving the effect of preventing fraud using a magnet at a low cost. The purpose is to provide.

In order to overcome the above-mentioned problems and achieve an intended purpose, a gaming machine according to claim 1 is:
A frame member (13) provided on the front side of the game board (20) and having a window portion (13a) opened at the front and rear at a position corresponding to the game board (20), and the back side of the frame member (13) A transparent member (30) disposed on the front side of the game board (20) and having a plurality of parallel transparent plates (31) surrounded by a frame body (32). A gaming machine (20) facing the window (13a) of the member (13) is configured to be viewed from the front side through the transparent member (30),

In addition, the entire window portion can be covered with the protruding portion by fitting the protective member to the window portion of the frame member, and the effect of preventing cheating on the entire game area is improved without using a plurality of magnetic sensors. It becomes possible. Further, since the entire front surface and rear surface of the protruding portion of the protective member are configured to be parallel to the transparent plate of the transparent member, the transparent board and the protective member (protruding portion) are permeated to visually recognize the game board. However, the distortion of the transmitted image is prevented, and the visibility of the game board is not lowered. And, because the installation surface portion of the protective member is fitted to the protruding portion inner peripheral side of the frame body whose inner peripheral shape is non-circular, the protective member is positioned in a predetermined posture with respect to the transparent member, Assembling workability of the frame member, the transparent member and the protective member is improved.

  The gist of the gaming machine according to claim 2 is that the thickness of the installation surface portion (61) is set to be equal to or less than the projecting dimension of the frame body (32) from the transparent plate (31).

  Thus, by setting the thickness of the installation surface portion to be equal to or less than the projecting dimension of the frame body from the transparent plate, the installation surface portion fitted to the inner peripheral side of the projecting portion of the frame body projects to the front side of the transparent member. Never do.

When the transparent member (30) supported by the support member (50) is fixed by the fixtures (51, 53), the installation surface portion (61) of the protection member (60) forms the window portion (13a). The gist is that it is configured to be sandwiched between the decorative part (55) and the transparent member (30).

  In this way, the transparent member supported by the support member provided on the back side of the frame member is detachably fixed by the fixture, so that the installation surface portion of the protective member is fixed in a state sandwiched between the decorative portion and the transparent member. It is possible to improve the workability and retention stability of the protective member.

  A gaming machine according to claim 4 includes holding means (70) for holding the protective member (60) in a detachable manner in a state where the installation surface portion (61) is fitted to the inner peripheral side of the frame (32). This is the summary.

  Thus, by holding the protective member by the holding means, the transparent member and the protective member can be handled integrally, and the detachability of the protective member is improved.

  That is, according to the gaming machine of the present invention, it is possible to prevent fraudulent acts using magnets without detecting the magnetism of the magnets with the magnetic sensor. Therefore, it is possible to reduce costs by reducing the number of magnetic sensors.

(3) In the embodiment, the projecting dimension of the projecting part from the installation surface part in the protective member is the minimum value of the separation dimension from the rear end part of the window part to the front end part of the opening (the rear end part to the front end part of the inner peripheral wall). Although it is equal to L _Min , even if the projecting dimension of the projecting portion is smaller than the minimum value L _Min of the separation dimension, not only does the protective member prevent the front of the frame member (front frame) from projecting, The protective member can be accommodated inside the opening of the window portion. Further, in the example, the separation dimension from the opening rear end portion to the opening front end portion in the lower opening portion (step portion) of the window portion is set to the minimum value, but the opening in the lower opening portion (step portion) of the window portion. Even if the separation distance from the rear end portion to the opening front end portion is not the minimum value, by setting the projection dimension of the projection portion from the installation surface portion to be equal to or less than the value of the separation dimension, The protective member can be prevented from protruding above the provided ball receiving portion, and the visibility of the ball receiving portion can be prevented from being lowered. Further, if the projecting dimension of the projecting part from the installation surface part is set to be at least the maximum value L _Max of the separation dimension from the opening rear end part of the window part to the opening front end part, the protective member becomes a frame member (front frame ) Can be prevented from protruding forward.
(4) In the embodiment, the outer peripheral shape of the installation surface portion of the protective member is smaller than the outer peripheral shape of the transparent member (glass unit), but the outer peripheral shape of the installation surface portion is changed to the outer peripheral shape of the transparent member (glass unit). The stability of the protective member when the transparent member (glass unit) is fixed to the frame member (front frame) via the fixture with the installation surface portion sandwiched therebetween is improved. The fixing device is not limited to the one shown in the embodiment, and a conventionally known fixing device is used as long as the transparent member (glass unit) can be detachably fixed to the frame member (front frame). can do.
(5) In the embodiment, the entire protective member is made of a transparent synthetic resin material, but at least the portion of the protruding portion that faces the front of the game area formed on the game board may be transparent. Therefore, a portion that is not located in front of the game area in the installation surface portion or the protruding portion may be opaque.
(6) In the embodiment, the thickness of the installation surface portion is matched with the protruding dimension of the protruding portion of the frame (holding frame) from the transparent plate (glass unit). By setting it to be less than the protruding dimension of the protruding part of the (holding frame), the installation surface part fitted to the inner peripheral side of the protruding part of the frame (holding frame) protrudes to the front side of the transparent member (glass unit) Can be prevented.
(7) The configuration of the holding means for detachably holding the protective member in a state where the installation surface portion is fitted to the inner peripheral side of the frame body (holding frame) is limited to the configuration shown in the second embodiment. Instead of this, an elastic hook may be formed on the frame (holding frame) side so that the protective member is locked and held. That is, as long as the protection member can be detachably held with respect to the frame (holding frame), conventionally known various types of holding means can be employed.
(8) In the embodiment, the rear end portion of the decorative portion in the frame member is configured to be in the same position as the rear surface of the flat plate member (base member), but the rear end portion of the decorative portion is formed as a flat plate member (base member). You may form so that it may protrude back from the rear surface. In this case, when the front surface of the installation surface portion of the protection member is brought into contact with the flat plate member (base member), the rear end portion of the decorative portion comes into contact with the installation surface portion in a pressing manner. It can be effectively prevented.
(9) Although the frame member (front frame) of the example is formed so that the inner peripheral shape of the window portion is slightly vertically long oval, it is not limited to this. That is, if the inner peripheral shape of the window is formed in a shape other than a circle, the protective member is positioned relative to the frame member (front frame) when the projection of the protective member is fitted to the window. It becomes possible to hold in this posture.
(10) The holding means for detachably holding the protective member in a state where the protruding portion is fitted to the window portion of the frame member (front frame) is not limited to the configuration shown in the third embodiment. Further, an elastic hook may be formed on the frame member (front frame) side so as to latch and hold the protective member. That is, as long as the protection member can be detachably held with respect to the frame member (front frame), conventionally known various types of holding means can be employed.
(11) In the embodiment, the frame member (front frame) is provided with the ball receiving portion (upper ball receiving tray). However, the frame member (front frame) and the ball receiving portion (upper ball receiving tray) are separated. It may be provided.
