By the way, the engagement receiving portion provided on the glass door side and rotatably receiving the engagement protrusion at the lower end of the glass unit has a slit-like portion inserted and inserted into the engagement protrusion. It has become.
Here, when a game ball is launched with the glass unit removed, the game ball may be fitted into the slit portion of the engagement receiving portion.
In addition, even if the game ball is not completely fitted, but placed in the slit, for example, an attempt to attach the glass unit without noticing the game ball, the engagement protrusion on the game ball If it is placed, the engagement receiving portion may be elastically deformed, and the game ball may be press-fitted and fitted.

Further, in this case, the engaging protrusion of the glass unit cannot be engaged with the engaging receiving portion. However, since the operator at this time has the glass unit with both hands, for example, The ball cannot be removed and it is necessary to place a glass unit once.
In such a case, there is a possibility of inducing a mistake of dropping the glass unit or hitting the glass unit.
In addition, since the game ball fitted in the slit of the engagement receiving portion is spherical, it is difficult to handle and it takes time to remove it from the slit portion of the engagement receiving portion. In particular, when the game ball is pushed and the engagement receiving portion is elastically deformed so that the game ball is sandwiched by the elastic force, it takes more time to remove the game ball.

  The present invention has been made in view of the above circumstances, and the glass unit is detachably attached to the glass door, and is provided on the lower side of the glass unit below the opening into which the glass unit of the glass door is fitted. When an engagement receiving portion that engages with the engagement protruding portion and receives the engagement protruding portion from the lower side is provided, it is possible to prevent the game ball from being fitted into the engagement receiving portion, and An object is to provide a gaming machine capable of improving the mounting work efficiency.

In order to solve the above-mentioned problem, a gaming machine according to claim 1, wherein a gaming board having a gaming area in which gaming balls flow down,
A glass door that covers the front surface of the game board at least so that the game area is visible and can be opened and closed;
A glass unit comprising a glass plate that is detachably provided on the glass door and covers the game area so as to be visible;
Fixed portions provided on the left and right of the upper end of the glass unit;
An engagement protrusion provided to protrude downward on the left and right of the lower end of the glass unit;
An opening provided in the glass door, in which the glass unit is detachably fitted;
A fixing member that is provided on the left and right above the opening of the glass door, and that fixes and unfixes the fixed part of the glass unit in a state of being fitted into the opening;
An engagement receiving portion that is provided on the left and right sides of the opening of the glass door and that engages with the engagement protrusion by inserting the engagement protrusion of the glass unit;
In a gaming machine comprising an insertion port into which the engagement protrusion of the engagement receiving portion is inserted,
The engagement receiving portion supports the engagement protrusion rotatably in a direction in which the upper side of the glass unit falls to the rear side and in a direction to return to the front side so as to be fitted into the opening,
The insertion port is characterized in that the width in the front-rear direction is narrowed by a length set so that the game ball is difficult to press-fit into the insertion port with respect to the diameter of the game ball.

  In the first aspect of the present invention, the insertion opening into which the engagement protrusion of the engagement receiving portion that supports the engagement protrusion provided on the left and right sides of the lower side of the glass unit detachably attached to the glass door is inserted. Since the front and rear widths are narrowed by a length set so that the game ball is difficult to press-fit into the insertion port, it is possible to prevent the game ball from being fitted into the engagement receiving portion.

  Note that the difficulty of press-fitting means that, for example, the force of a human finger or a force about the load of the glass unit indicates that the game ball is not press-fitted into the insertion port of the engagement receiving portion. A completely impossible state is also included, for example, including a case where the engagement receiving portion is damaged when a game ball is forcibly inserted.

  Further, the front-rear direction in the front-rear width of the insertion port of the engagement receiving portion, that is, the front-rear direction in the glass door and the glass unit, refers to the side facing the player when the player is playing with the gaming machine. The direction is the front, the side facing the game board is the rear, and the direction is substantially orthogonal to the glass surface of the glass unit of the glass door.

Here, if the front-rear width of the insertion slot is wider than the diameter of the game ball, the game ball enters the insertion slot, making it difficult to take the game ball, and it takes time to remove the game ball. In this case, however, the game ball can be removed by grasping it with two fingers or scooping it up with a thin rod-like member (such as a pen).
On the other hand, when the front and rear width of the insertion port is the same as or slightly narrower than that of the game ball, there is a risk that the game ball will be pressed into the insertion port, due to the elastic deformation of the member forming the insertion port. When inserted, it becomes difficult to remove the game ball from the insertion slot.

  Therefore, the insertion port is not simply made narrower than the diameter of the game ball, but the elastic deformation of the members constituting the engagement receiving portion is considered. It is necessary to make the width in the front-rear direction of the entrance smaller than the diameter of the game ball by a length set so that the game ball does not fit into the game ball.

  Whether or not the game ball is press-fitted into the loading port depends on the load applied to the game ball, the material (elastic coefficient, etc.) and shape of the engagement receiving portion, and the front-rear width of the insertion port of the engagement receiving portion. Will do. Therefore, for example, the load applied to the game ball is the weight of the glass unit, or about 1/2 or 1/3 of the glass unit, and the material of the engagement receiving portion is a synthetic resin currently used, By changing the width of the insertion port of the engagement receiving portion experimentally, the optimum width of the insertion port can be set.

  Thereby, a game ball does not fit in an insertion port, and the attachment operation | work of the glass unit to a glass door can be made efficient. That is, without knowing that the game ball is in the insertion slot, trying to attach the glass unit, the glass unit cannot be installed, or the game ball in the insertion slot is pushed in with the glass unit, and the game ball becomes more difficult to take. Can be prevented. Moreover, the operation | work which removes the game ball fitted to the insertion port before inserting a glass unit can be made easy.

Even if the game ball does not fit into the insertion slot, the glass unit cannot be attached without removing the game ball even if the game ball can be easily removed from the insertion slot when the game ball is placed on the insertion slot. Therefore, for example, it is preferable that the structure is such that the game ball is difficult to be placed on the insertion slot.
Here, the front corresponds to the front surface of the gaming machine, and the rear corresponds to the back surface of the game ball. Therefore, the direction from the back to the front of the gaming machine is the forward direction, and the direction from the front to the back of the gaming machine is the backward.

In the gaming machine according to claim 2, the lower end portion of the engagement protruding portion is provided with an arc convex portion that protrudes rearward and has a rear end surface that is convex in a substantially circular arc shape,
The engagement receiving portion is in contact with the rear end surface of the arc convex portion, and the arc convex portion rotates in a direction in which the glass unit falls to the rear side and a direction to fit the opening of the glass door toward the front side. The arc guide piece has a substantially arc-shaped cross section to guide the arc guide piece, and the tip end portion of the arc guide piece is above the portion projecting to the rearmost side of the arc convex portion and wraps around to the front side from the portion. It is formed by.

According to a second aspect of the present invention, an arc guide piece is provided with an arc projection on the engagement protrusion, and the engagement receiving portion abuts against the rear end surface of the arc projection to guide the rotational movement of the glass unit. The arc guide piece is formed so as to wrap around the front side above the portion of the arc convex portion that protrudes to the rearmost side, so that the arc convex portion is engaged with the arc guide portion. The upward movement of the part is restricted.
By restricting the upward movement of the arc convex part, the upward movement of the glass unit having the arc convex part is restricted.

  Here, when the gaming machine is removed from the island equipment of the amusement store, for example, when the removed gaming machine is placed on the floor a little roughly with the glass unit attached, it is placed on the floor. In some cases, a force may be applied so that the glass unit moves upward with respect to the gaming machine. In this case, conventionally, the lower side of the glass unit is in a state of being received so that the glass unit does not move downward, so the movement of the glass unit to the upper side is not restricted, and the force to move to the upper side of the glass unit is It will be applied to the fixed part on the upper side of the glass unit and the fixing member fixing the fixed part. As a result, there is a possibility that problems such as cracks in the fixed portion and the fixing member may occur.

  On the other hand, the upward movement of the glass unit is restricted by the arc convex portion and the arc guide portion as described above, so that an upward force is applied to the glass unit due to an impact when the gaming machine is placed. Even in this case, the force acts on the fixing member and the arc guide portion in a distributed manner, and damage to the fixed portion and cracks of the fixing member can be prevented.

  In addition, the tip end portion of the arc guide portion extends to the front side from the rearmost portion of the arc convex portion, thereby making it possible to narrow the width of the insertion port. That is, by extending the front end portion of the arc guide portion to the front side, the upward movement of the glass unit can be restricted, and the width of the insertion port can be narrowed so that the game ball cannot be press-fitted into the insertion port. One effect can be obtained.

  With reference to FIGS. 4-11, the attachment structure of the glass unit 5 of the glass unit 5 and the glass door 4 is demonstrated. The glass door 4 shown in FIGS. 4 to 11 is a synthetic resin plate part serving as a base of the glass door 4, and illustration of each member attached to the synthetic resin plate part is omitted. .

The glass unit 5 is obtained by integrally bonding these glass plates 5a with a bonding member 5b at the peripheral portion of the glass plates 5a in a state where two glass plates 5a are arranged in parallel and spaced apart from each other. It is.
2 and 3, the upper portion of the glass unit 5 is provided with a protruding portion 5 c that protrudes upward and has a flat upper surface. The protruding portion 5 c is provided on the back side of the glass door 4. It accommodates in the accommodating part 4b provided above the opening part 4a, and hold | maintains the upper position of the glass unit 5 with respect to the glass door 4 from the back side. The holding | maintenance in the other site | part of the glass unit 5 is mentioned later.

As shown in FIG. 7, fixed portions 13 are provided on the left and right of the upper end portion of the glass unit 5 so as to protrude upward.
The fixed portion 13 is formed in a plate shape and includes an engagement hole portion 13 a that engages with the fixing member 25 when fixed to a fixing member 25 described later. Moreover, the base end part of the to-be-fixed part 13 becomes the shape integrally provided in the joining member 5b. The front surface of the fixed portion 13 is disposed slightly in front of the front surface of the glass plate 5 a on the front side of the glass unit 5.

Further, the glass plate 5a of the glass unit 5 is formed in an arc shape on the upper end side, the center is high, and the height is lowered as the distance from the center increases. It is lower than the upper ends of the left and right central portions of the glass plate 5a, and the distal end portion of the fixed portion 13 is at substantially the same height as the upper end of the glass plate 5a.
The fixed portion 13 is fixed by a fixing member 25 described later of the glass door 4 so as to be switchable between a state fixed to the glass door 4 and a state where the fixing is released.

  As shown in FIGS. 8 and 11, on the left and right sides of the lower end of the glass unit 5, there are provided engaging protrusions 15 that protrude downward from the bonding member 5 b at the lower edge of the glass plate 5 a. The engagement protrusion 15 includes a plate-like plate portion 15a protruding downward in the figure and an arc convex portion 15b protruding rearward (rightward in the drawing) from the lower end portion of the plate portion 15a. Prepare. The plate portion 15a is arranged in parallel to the surface of the glass plate 5a and protrudes below the lower end of the glass plate 5a and the lower end of the joining member 5b. Moreover, the front-rear position of the plate portion 15a is slightly more forward than the center position in the thickness direction of the glass unit 5, and is closer to the rear than the front surface of the front glass plate 5a.

The arcuate convex portion 15b is provided bent in an L shape rearward from the lower end of the plate portion 15a. And the end surface which faces the back of the circular arc convex part 15b is formed in the semicircle shape in the cross section. This semicircle is a shape obtained by cutting the circle in half along a line along the vertical direction. Thereby, the approximate center of the thickness in the front-rear direction (left and right in FIG. 11) of the arc convex portion 15b is the portion that protrudes most backward.
The engagement protrusion 15 engages with an engagement receiving portion 27 described later of the glass door 4.

As shown in FIGS. 4 to 7 and 9, fixing members 25 for fixing the fixed portion 13 of the glass unit 5 are fixed to the glass door 4 on the left and right sides of the opening 4 a of the glass door 4. It is provided corresponding to the position of the fixed part 13 of the glass unit 5 to be provided.
The fixing member 25 is provided on the back side of the glass door 4. The fixing member 25 is provided on the upper side of the position where the fixed part 13 is arranged when the glass unit 5 is installed on the glass door 4, and is rotatable to the shaft part 25 a and the shaft part 25 a. The rotating member 25b is supported, an operation lever 25c for operating the rotation of the rotating member 25b, and a stopper 25d for regulating the rotation range of the rotating member 25b.

  A rotary member 25b is rotatably supported on the shaft portion 25a, and an operation lever 25c is provided on the rotary member 25b so as to be rotatable integrally therewith. The rotating member 25b is arranged to extend downward from the shaft portion 25a in a state in which the fixed portion 13 is fixed, and in a state in which the fixing of the fixed portion 13 is released, the rotating member 25b is moved from the fixed state. It rotates 90 degrees and faces the outside from the shaft portion 25a (right side of the right fixing member 25b and left side of the left fixing member 25 when viewed from the back). Note that the rotation of 90 degrees or more from the fixed state is regulated by the stopper 25d.

  Further, the rotating member 25b is provided with an engaging convex portion 25e that engages with the engaging hole portion 13a of the fixed portion 13 in a state of being overlapped with the fixed portion 13 so as to fix the fixed portion 13. Yes. The engaging convex portion 25e is provided so as to protrude forward from the front surface of the rotating member 25b, and is engaged in a state where the tip is inserted into the engaging hole portion 13a of the fixed portion 13 that is overlapped with the front side of the rotating member 25b. To do.

  As shown in FIGS. 4 to 6, 8, 10, and 11, the glass unit 4 receives the engaging protrusions 15 of the glass unit 5 on the left and right sides below the opening 4 a of the glass door 4. 5 is provided on the back surface of the glass door 4 corresponding to the position of the engagement protrusion 15 of the glass unit 5 fixed to the glass door 4. . The left and right engagement receiving portions 27 have different left and right widths and the like, but the cross-sectional structures of the portions with which the engagement protrusions 15 are engaged are the same.

  As shown in FIGS. 8 and 11, the engagement receiving portion 27 is a substantially horizontal plate-like support plate portion that restricts the downward movement of the engagement protrusion 15 in a state where the engagement protrusion 15 is inserted. 27a, an arc guide piece 27b formed to extend in an arc shape from the rear to the upper side of the support plate portion 27a, and an insertion port 27c for inserting the engagement protrusion 15 between the tip of the arc guide piece 27b. And an edge member 27d.

The arc guide piece 27b is formed in an arc shape in cross section along the end surface of the arc convex portion 15b of the engagement protrusion 15 described above. Therefore, the circular arc guide piece 27b has a shape that extends upward from a portion that protrudes most rearward from the lower end of the circular arc convex portion 15b and wraps forward from the portion.
Therefore, in a state in which the arc convex portion 15b enters the portion that becomes the concave side of the arc guide piece 27b, the upward movement of the arc convex portion 15b is restricted by the tip portion of the arc guide piece 27b.

  Further, in a state in which the arc convex portion 15b enters the concave portion of the arc guide piece 27b, the rotational movement in the direction in which the plate portion 15a of the engagement protrusion 15 falls to the rear side and the direction to rise to the front side is guided. It has come to be. Further, the rotation of the circular arc convex portion 15b within the circular arc guide piece 27b is such that the glass unit 5 is fitted into the opening 4a of the glass door 4, so that the rotation of the front side is substantially perpendicular to the plate portion 15a (glass unit 5). It is regulated in the state.

  Further, the rotation of the glass unit 5 in the direction in which the glass unit 5 is tilted rearward is restricted by contact between the tip of the arc guide piece 27b and the plate portion 15a, but the arc convex portion 15b moves away from the arc guide piece 27b. However, the range of rotation in the direction in which the glass unit 5 falls is widened by rolling the upper surface of the support plate portion 27a with the arc convex portion 15b facing downward.

  Also, as shown in FIG. 11, an insertion port 27c into which the engagement protrusion 15 is inserted is formed between the tip 27e of the arc guide piece 27b and the tip 27f of the edge member 27d. The insertion port 27c may be slit-shaped. The front-rear width of the insertion port 27c is the shortest distance between the tip 27e of the arc guide piece 27b and the tip 27f of the edge member 27d. At this time, since the tip 27e of the arc guide piece 27b is located below the tip 27f of the edge member 27d, the shortest distance is a distance on an obliquely inclined line.

  The front-rear width of the insertion port 27c is shorter by a length set with respect to the diameter of the game ball. This set length is obtained experimentally, for example. For example, even if the game ball is pushed in with a load corresponding to about half of the weight of the glass unit 5, the game ball is fitted into the insertion slot 27c. The length does not fall below the insertion opening 27c. However, the front-rear width of the insertion port 27c needs to be wider than the minimum front-rear width in which the engagement protrusion 15 can be inserted, and the arc guide 27c becomes narrower than that. It is necessary to increase the thickness of the piece 27b or the edge member 27d, or to change the material to a hard material.

Further, when the game ball is placed on the insertion port 27c between the tip 27e of the arc guide piece 27b and the tip 27f of the edge member 27d, the game ball is placed on the insertion port 27c as it is and stabilized. It is preferable that the structure is difficult to be brought into a state.
For example, the distance in the horizontal direction when the tip 27e of the arc guide piece 27b and the tip 27f of the edge member 27d are viewed vertically from below is less than the radius of the game ball. The vertical distance when the tip 27e of the arc guide piece 27b and the tip 27f of the edge member 27d are viewed horizontally from the side is preferably equal to or less than the radius of the game ball and longer than zero.

  In such a gaming machine, when the glass unit 5 of the glass door 4 is attached, the glass unit 5 is attached on the back side of the glass door 4 in a state where the glass door 4 is opened with respect to the machine frame 1. At this time, the engaging protrusion 15 on the lower end side of the glass unit 5 is inserted into the engaging receiving portion 27 from the insertion port 27c with the glass unit 5 being inclined. In this state, the arc convex portion 15b of the engagement protrusion 15 is in contact with the support plate portion 27a.

  In this state, when the glass unit 5 is raised while rotating the upper end of the glass unit 5 toward the front side, the arc convex portion 15b enters the concave portion of the arc guide piece 27b, and the arc convex portion 15b becomes the arc guide piece. After the state guided by 27 b, the glass unit 5 is fitted into the opening 4 a of the glass door 4.

At this time, the fixing member 25 of the glass door 4 needs to be arranged at a position where the fixing of the fixed portion 13 of the glass unit 5 is released. That is, the rotating member 25b of the fixed member 25 needs to be substantially horizontal facing the outside.
With the glass unit 5 fitted in the opening 4a, the fixing member 25 is turned to the fixed position by rotating the rotating member 25b of the fixing member 25 using the operation lever 25c. The rotating member 25 b overlaps the rear side of the portion 13, and the engaging convex portion 25 e of the fixing member 25 is engaged with the engaging hole portion 13 a of the fixed portion 13.

  Thereby, the glass unit 5 is fixed to the glass door 4. When removing the glass unit 5 from the glass door 4, the fixing member 25 is not fixed, the glass unit 5 is tilted obliquely rearward, and the engagement protrusion 15 is removed from the engagement receiving portion 27. Thus, the glass unit 5 is moved obliquely upward.

  In such a gaming machine, the game ball can be prevented from being fitted into the insertion port 27c of the engagement receiving portion 27 as described above, and the game ball is placed on the insertion port 27c of the engagement receiving portion 27. When the engagement protrusion 15 of the glass unit 5 is inserted into the engagement receiver 27 in order to attach the glass unit 5 to the glass door 4, the engagement receiver 27 is inserted. There are no game balls placed on the mouth portion 27c and no game balls fitted into the insertion port 27c, and there is no need to perform an operation for removing these game balls. Therefore, the glass unit 5 can be fixed to the glass door 4. That is, the workability of attaching the glass unit 5 to the glass door 4 can be improved.

  In particular, the operation of attaching the glass unit 5 can be greatly shortened as compared with the case where the game ball is fitted into the insertion slot 27c or falls below the insertion port 27c and relatively troublesome in removing the game ball. As a result, when the glass unit 5 is attached to a large number of gaming machines, it is not necessary to remove the gaming balls in some gaming machines, and the working time is shortened. Can do.

  In addition, since the arc guide piece 27b of the engagement receiving portion 27 of the glass door 4 wraps around the arc convex portion 15b of the engagement protrusion 15 of the glass unit 5, the glass unit 5 is attached to the glass door 4. It is possible to prevent the fixed unit 13 and the fixing member 25 from being damaged due to the impact when the pachinko gaming machine in a fixed state is placed on the floor and the glass unit 5 is raised upward.

  Further, the front end portion of the arc guide piece 27b is extended so as to wrap around the front side above the arc convex portion 15b, so that the front-rear width of the insertion port 27c can be reduced and the glass unit 5 can be prevented from moving upward. Thus, both of the above two effects can be obtained.

  As mentioned above, although embodiment which applied the invention made by this inventor was described, this invention is not limited by the description and drawing which make a part of indication of this invention by this embodiment. That is, it should be added that other embodiments, examples, operation techniques, and the like made by those skilled in the art based on this embodiment are all included in the scope of the present invention.
