JP 2009-072567 A

  In the configuration in which the first holding frame and the second holding frame are biased in a direction away from each other by the elastic member as in the transparent plate holding frame of Patent Document 1, the game board and the rear panel are caused by individual differences in the gaming machine frame. It is possible to set the distance between the game board and the rear transparent board to be constant by absorbing the distance variation with the transparent board on the side, and the mischievous act (the player pulls the front frame forward) It is possible to prevent an increase in the distance between the game board and the rear transparent plate due to fraud. That is, it is possible to prevent the occurrence of clogging due to the change in the distance.

  Here, in the transparent plate holding frame of Patent Document 1, the elastic member is arranged so as to directly urge between the first holding frame and the second holding frame. That is, the rear transparent plate (holding frame) that keeps the distance from the front of the game board constant is arranged with reference to the front transparent plate (holding frame). The transparent plate on the front side is exposed from the window of the front frame and can be touched by the player. If a gap or the like occurs, it is likely to become a target of an unauthorized player, and prevents illegal activities including mischief as described above. From the viewpoint, it is desirable that the urging force to the rear transparent plate is separated from the front transparent plate.

  In addition, considering the occurrence of individual differences in the gaming machine frame as described above, not only the front transparent plate (holding frame) directly fixed to the front frame, but also the rear transparent plate (holding frame) It is desirable to fix (bias) the frame as a reference to improve the assembly accuracy.

  The present invention has been made in view of the above circumstances, and in a transparent plate unit including a pair of transparent plate members, the rear transparent plate member is fixed as a front frame reference to improve the assembling accuracy and fraud. An object of the present invention is to provide a reliable gaming machine with an enhanced prevention effect.

In order to solve the above problems, the gaming machine of the present invention is:
An inner frame that holds a game board that forms a game area on the front side, a front frame that forms a window corresponding to the game area and that can be opened and closed on the front side of the inner frame, and a rear side of the front frame Transparent having a pair of front and rear transparent plate members that are detachably arranged to close the window portion and allow the game area to be visually recognized through the window portion when the front frame is closed with respect to the inner frame A gaming machine comprising a board unit,
The transparent plate unit
Of the pair of transparent plate members, the front transparent plate member disposed on the front side which is the player side and exposed from the window portion, and
A front holding frame that holds the front transparent plate member and is detachably fixed by a fixing means of the front frame;
Of the pair of transparent plate members, a rear transparent plate member disposed opposite to the game board on the rear side of the front transparent plate member;
A rear holding frame for holding the rear transparent plate member;
Between the front holding frame and the rear holding frame, a joining means for joining the pair of transparent plate members so as to be relatively movable within a predetermined range of width,
When the transparent plate unit is arranged in the front frame, the rear transparent plate member is urged rearward through the rear holding frame with the back surface of the front frame as a starting point, while the transparent plate unit is arranged in the front frame. And a biasing means for biasing the pair of transparent plate members between the front holding frame and the rear holding frame in a direction to separate them.

  According to the gaming machine of the present invention, in the transparent plate unit including a pair of transparent plate members, the front holding frame and the rear holding frame are relatively connected to each other within a predetermined range by the joining means. Are movably joined. When the transparent plate unit is arranged on the front frame, the rear transparent plate member is urged rearward by the urging means with the back surface of the front frame as the starting end through the rear holding frame. According to this, the rear transparent plate member (rear holding frame) in a state where the rear transparent plate member (rear holding frame) and the front transparent plate member (front holding frame) are stably joined by the joining means. ) Is fixed (biased) as the front frame reference, so that the transparent plate unit itself is not only stabilized, but also the accuracy of assembly to the front frame can be increased. Also, since the urging force by the urging means is not acting between the front transparent plate member and the rear transparent plate member, even if the player receives a shock, for example, by hitting the player, The rear transparent plate member is not affected, and the game ball can flow smoothly through the game area without any hindrance. As a result, it is possible to provide a reliable gaming machine with an increased anti-fraud effect.

  Further, when the transparent plate unit is not disposed on the front frame, the biasing means biases the pair of transparent plate members in a direction in which they are separated from each other between the front holding frame and the rear holding frame. According to this, a pair of transparent plate members can be stored and transported in a safe state without colliding with each other. That is, the urging means can switch between the front frame and the front holding frame as the other side for urging the rear holding frame depending on whether or not the transparent plate unit is arranged on the front frame. There is a good effect.

The urging means includes a compression coil spring having one end side disposed on the rear holding frame, and a spring receiving member disposed on the other end side of the compression coil spring and receiving the urging force of the compression coil spring,
The front holding frame is formed with a through-hole through which a part of the spring receiving member arranged from the rear side can protrude to the front side,
When the transparent plate unit is arranged on the front frame, a part of the spring receiving member that can be protruded is pushed into the through hole by the rear surface of the front frame, and the rear surface of the front frame is set as the start via the spring receiving member. The rear holding frame can be configured to be biased rearward.

  According to this, a through hole is formed in the front holding frame, and a spring receiving member is arranged in the through hole, and the rear holding frame is urged rearward with the rear surface of the front frame as a starting point. be able to. Further, since the rear holding frame is urged in such a manner that the spring receiving member is pushed into the through hole, a sufficient urging force (restoring force) by the compression coil spring can be obtained.

In addition, in the gaming machine, when the transparent plate unit is not disposed on the front frame, the spring receiving member is engaged with the front holding frame with a part of the spring receiving member protruding from the through hole to the front side of the front holding frame. The rear holding frame and the front holding frame can be configured to be biased in the direction of separating from each other.

  According to this, since a part of the spring receiving member protrudes from the through hole, it plays a role of a spacer when the transparent plate units are arranged at the time of storage or transportation, and the transparent plate member of the adjacent transparent plate unit is Colliding with each other can be prevented. In addition, since the spring receiving member is interposed in the form of locking to the front holding frame, the urging force of the compression coil spring can be efficiently transmitted to the front holding frame, and the front holding frame and the rear holding frame can be stably connected. Can be maintained.

  In addition, the game board or the inner frame receives a rear holding frame to keep the distance between the board surface of the game board and the rear transparent plate member constant when the front frame is closed with respect to the inner frame. The contact portion is provided, and the rear transparent plate member can be configured to be held at an intermediate position in the interval width within a predetermined range when the rear holding frame contacts the contact portion.

  According to this, since the rear holding frame (rear transparent plate member) urged rearward with respect to the front frame is received by the abutting portion on the game board or the inner frame side, the game board and the rear transparent board The distance between the members can be made constant. At that time, since the rear holding frame is set so as to be held at an intermediate position within a predetermined range of distance that can be moved relative to the front holding frame, the individual body of the gaming machine main body such as the inner frame or the front frame It is possible to absorb variations due to the difference and prevent an excessive load or breakage during the opening / closing operation of the front frame. In addition, since the rear holding frame is held in a state where the contact portion is pressed, it is possible to stably contact and make the distance between the game board and the rear transparent plate member constant.

On the side.

  Hereinafter, the transparent plate unit 7 will be described in detail. As shown in FIGS. 2 to 6, the transparent plate unit 7 is disposed on the front side which is the player side of the pair of transparent plate members, and is exposed from the window portion 41 of the front frame 4. A front holding frame 73 that holds the front transparent plate member 71 and is detachably fixed by the fixing means 44 of the front frame 4, and faces the game board on the rear side of the front transparent plate member 71 of the pair of transparent plate members. A rear transparent plate member 72 to be arranged and a rear holding frame 74 for holding the rear transparent plate member 72 are provided. The front transparent plate member 71 and the rear transparent plate member 72 are, for example, circular, elliptical (race track shape, oval shape) or rectangular transparent glass plates.

  Further, the transparent plate unit 7 can relatively move the front transparent plate member 71 and the rear transparent plate member 72 within a predetermined range width W between the front holding frame 73 and the rear holding frame 74. When the transparent plate unit 7 is disposed on the front frame 4, the rear transparent plate member 72 is attached to the rear via the rear holding frame 74 with the back surface 4 a of the front frame 4 as the starting point. Biasing means 90 for biasing. When the transparent plate unit 7 is not disposed on the front frame 4, the urging means 90 includes the front transparent plate member 71 and the rear transparent plate member 72 between the front holding frame 73 and the rear holding frame 74. Are urged in the direction of separating each.

  The front holding frame 73 has a frame shape, and an opening 73a into which the front transparent plate member 71 is fitted, and the joining means 80 and the urging means 90 are arranged (formed) extending outside the opening 73a. Corner portions 73b (four in this embodiment). An adhesive or the like is applied to the opening 73a, and the front transparent plate member 71 is press-fitted from the front side. Each corner 73b is formed with a through-hole 73c penetrating in the thickness direction. Further, a locking piece 73d fixed by the fixing means 44 of the front frame 4 is formed on the side of each corner 73b.

  The rear holding frame 74 has a frame shape, and an opening 74a into which the rear transparent plate member 72 is fitted, and the joining means 80 and the urging means 90 are disposed (formed) extending outside the opening 74a. ) Corner portions 74b (four in this embodiment). An adhesive or the like is applied to the opening 74a, and the rear transparent plate member 72 is press-fitted from the rear side. Each corner portion 74b is formed with a mounting portion 74c protruding in a cylindrical shape to which the biasing means 90 is assembled.

  As shown in FIGS. 5 and 6, the joining means 80 is formed so as to penetrate the boss portions 81 formed on the rear surface side of the respective corner portions 73 b of the front holding frame 73 and the respective corner portions 74 b of the rear holding frame 74. The insertion hole 82 and the seated screw 83 fastened to the boss 81 are configured. Therefore, in the joining means 80, the boss 81 is inserted into the insertion hole 82, and the seated screw 83 is fastened to the tip of the boss 81, so that the corner 74b (rear holding frame 74) is the seated screw 83. The front holding frame 73 and the rear holding frame 74 are slidably joined to each other by the difference between the height of the boss 81 and the thickness of the corner 74b. That is, as shown in FIG. 6, the transparent plate unit 7 is thinned by the difference (interval width W) from the thickness DM in the state where the front holding frame 73 and the rear holding frame 74 are most separated by the urging means. Can be deformed (stretched). In other words, when the transparent plate unit 7 is disposed on the front frame 4 (when the front holding frame 73 is fixed to the front frame 4), the rear holding frame 74 is a distance (thickness) from the rear surface of the front frame 4. DM can be maximized, and can be arranged to be movable by the difference (interval width W).

  Specifically, when the height of the boss 81 is H and the thickness of each corner 74b (the length of the insertion hole 82) at the end (near) of the insertion hole 82 is h, the interval width W in a predetermined range is It can be expressed by a value obtained by subtracting the thickness h of the corner portion 74b from the height H of the boss portion 81. At this time, the interval width W is desirably set to be larger than 1 mm and smaller than 5 mm, for example. More preferably, the interval width W is desirably set to approximately 3 mm (greater than 2.5 mm and smaller than 3.5 mm). As shown in FIG. 8, the interval width W is the interval width between the base end portion of the boss portion 81 and the front end portion of the insertion hole 82, and the tip end portion (the seated screw 83) of the boss portion 81 and the insertion hole. 82, when the interval width between the rear end portion is W2, it can be expressed by adding W1 and W2 (W = W1 + W2).

  Here, regarding the structure of the game board (game board 5), it is standard that it is parallel to the glass plate (rear transparent plate member 72), and the distance between them exceeds 13 mm and does not exceed 25 mm. Yes. Usually, the distance between the game board 5 and the rear transparent plate member 72 is set (standard) so that the diameter of the game ball is 11 mm, so that it does not exceed 22 mm corresponding to the distance of two game balls. Is generally set to 20 mm. If the distance between the game board 5 and the rear transparent plate member 72 is 22 mm or more for two game balls due to individual differences of the game machines 1, ball clogging is likely to occur between them, and the game There arises a problem that the ball does not enter the winning opening, and even if it does not exceed 25 mm, it may be treated as a general defective product in the accuracy and gaming nature of the gaming machine 1. Therefore, by setting the interval width W in the transparent plate unit 7 to around 3 mm, the variation is absorbed so that the distance between the gaming board 5 regarded as a defective product and the rear transparent plate member 72 does not exceed 22 mm, A set distance (19 mm to 20 mm) can be formed without any problem.

In addition, by setting the interval width W within the above range, the front holding frame 73 and the rear holding frame 74 can be stably assembled. If the interval width W is smaller than 1 mm, there is a possibility that variations in the distance between the game board 5 and the rear transparent plate member 72 due to individual differences of the gaming machines 1 cannot be sufficiently absorbed. Further, when the interval width W is larger than 5 mm, not only the transparent plate unit 7 is increased in size but also the sliding range between the front holding frame 73 and the rear holding frame 74 is increased, and rattling or the like occurs and is stable. There is a possibility that the sex is disturbed.

  The biasing means 90 includes a compression coil spring 91 whose one end is disposed on the rear holding frame 74, and a spring receiving member 92 that is disposed on the other end of the compression coil spring 91 and receives the biasing force of the compression coil spring 91. It has.

  As shown in FIG. 5, the spring receiving member 92 includes a bottom wall portion 92a protruding from the through hole 73c of the front holding frame 73, an outer peripheral wall portion 92b rising from the outer peripheral edge of the bottom wall portion 92a, and a bottom wall portion 92a. And an inner peripheral wall portion 92c that rises in a cylindrical shape from the central region of the inner region. In the spring receiving member 92, a bottomed space portion having an annular opening is formed by the outer peripheral wall portion 92b and the inner peripheral wall portion 92c, and the compression coil spring 91 is inserted from the opening. In addition, a stepped locking portion 92d whose opening side is widened (expanded) is formed on the outer peripheral surface of the outer peripheral wall portion 92b, and is prevented from coming off from the through hole 73c of the front holding frame 73 by the locking portion 92d. .

  The spring receiving member 92 has an inner peripheral wall portion 92c inserted through the through hole of the mounting portion 74c of the rear holding frame 74, and a seated screw 93 is fastened to the tip of the spring receiving member 92. It is fixed so as to be relatively slidable within the interval width (distance) of the range. The compression coil spring 91 is disposed so as to be supported from the inside by the mounting portion 74c and from the outside by the outer peripheral wall portion 92b, and the rear holding frame 74 and the spring receiving member 92 are separated from each other. Energize to. Therefore, when the transparent plate unit 7 is not disposed on the front frame 4, the locking portion 92d abuts (locks) to the edge portion of the through hole 73c by the urging force of the compression coil spring 91, and the front side holding is performed. The frame 73 and the rear holding frame 74 are biased in the direction of separating (see FIG. 6). At this time, the spring receiving member 92 is formed so that at least a part of the bottom wall portion 92a protrudes from the through hole 73c.

  The fixing means 44 provided on the back surface 4a of the front frame 4 is such that the lower fixing means 44c and 44d are in the form of a holder, and the lower retaining pieces 73d and 73d of the front holding frame 73 are from the top to the bottom. It is slid in the direction and regulates movement in directions other than the top. At this time, if the lower locking pieces 73d, 73d are wedge-shaped, the insertion is easy and can be stably fixed. The upper fixing means 44a and 44b are provided so as to be rotatable in parallel with the back surface 4a between the retracted position and the restricting position, and the upper retaining pieces 73d and 73d of the front holding frame 73 are disposed on the back surface at the restricting position. Fix it so that it presses against 4a. The fixing means 44 is not limited to these embodiments, and any means may be used as long as the front holding frame 73 can be fixed to the rear surface 4a of the front frame 4.

  Next, the operation of the transparent plate unit 7 will be described. First, when the transparent plate unit 7 is not disposed on the front frame 4, the spring receiving member 92 and the rear holding frame 74 are separated from each other by the urging force of the compression coil spring 91 as shown in FIG. 6. Be energized by. Then, in a state where a part (bottom wall portion 92a) of the spring receiving member 92 protrudes from the through hole 73c to the front side of the front holding frame 73 (corner portion 73b), the locking portion 92d of the spring receiving member 92 holds the front side. The front holding frame 73 and the rear holding frame 74 are urged in a direction separating from each other by contacting (pressing) a step formed on the inner wall of the through hole 73 c of the frame 73, and the through hole 82 of the joining means 80. Is held at a position where the end portion (corner portion 74 b) abuts against the seated screw 83. In other words, the front holding frame 73 and the rear holding frame 74 are held at the most distant positions (the state in which the front holding frame 73 and the rear holding frame 74 have the thickness DM: W1 = W (maximum), W2 = 0). Has been.

Subsequently, as described above, when the transparent plate unit 7 is fixedly arranged on the front frame 4 via the fixing means 44, as shown in FIG. ) Is held at a position where it abuts against the seated screw 83, a part (bottom wall portion 92a) from which the spring receiving member 92 can protrude is pushed into the through hole 73c by the rear surface 4a of the front frame 4. At this time, the rear holding frame 74 is positioned so that the end portion (corner portion 74 b) of the through hole 82 of the joining means 80 abuts against the seated screw 83 (the front holding frame 73 and the rear side) by the biasing force of the compression coil spring 91. The holding frame 74 is held as it is in a state where the thickness DM becomes W1 = W (maximum), W2 = 0). That is, the rear holding frame 74 is urged rearward with the rear surface 4a of the front frame 4 as the starting end via the spring receiving member 92.

  As shown in FIG. 8, when the front frame 4 is in a closed state with respect to the inner frame 3, the rear transparent plate member 72 is arranged in parallel at a position spaced apart from the board surface of the game board 5 by a predetermined distance. The Specifically, the rear transparent plate member 72 is positioned at a midway position (thickness) of a predetermined range of a width within which the rear holding frame 74 is slightly pushed back by abutting against the abutting portion 51 and is relatively movable. D state: a state in which W2 is subtracted from maximum thickness DM; W1 = W−W2, 0 <W2 <W). That is, the through hole 82 is held at a midway position of the boss portion 81 of the joining means 80. As a result, even when the front frame 4 is slightly moved in the front-rear direction, the rear holding frame 74 can be held in contact with the contact portion 51. As a result, the game board 5 and the rear transparent plate can be held. The distance from the member 72 can be kept constant. For example, as in the game board 5 (contact portion 51) shown by the phantom line in FIG. The distance between the game board 5 and the rear transparent plate member 72 can be kept constant up to the maximum separation distance position where the portion 74b) contacts the seated screw 83. Eventually, variations in the distance between the game board 5 and the rear transparent plate member 72 due to individual differences in the gaming machine frames such as the inner frame 3 and the front frame 4 are absorbed, and the game board 5 and the rear transparent plate member 72 are separated. The distance can be set constant.

  In the present invention, a pachinko machine has been described as an example of a gaming machine. However, the present invention can be applied to a gaming machine provided with a transparent plate unit such as an arrangement ball gaming machine or a sparrow ball gaming machine.
