Description

The present invention relates to a game machine such as a pachinko machine or a slot machine.

As a type of gaming machine, a gaming board equipped with a winning device and a symbol display device is installed on the upper front surface of the main body base such as a machine frame and a mechanism plate, and a gaming ball is operated by operating a launching handle installed on the front surface. There is known a pachinko machine that launches a machine on the upper part of the game board and allows it to flow down on the game board. Further, in a normal pachinko machine, a front door fitted with a glass plate is attached to the base of the main body so as to cover the front surface of the game board so that it can be opened on one side. When a situation occurs, the front door can be opened to eliminate such a situation. Further, in such a pachinko machine whose front door can be opened and closed, as in Patent Document 1, when the front door is closed with respect to the base of the main body, a protrusion formed below the glass plate on the back surface of the front door is formed. In some cases, the body is inserted into a concave portion formed below the installation portion of the game board at the base of the main body so that the vertical and horizontal positions of the front door with respect to the base of the main body are not displaced.

Japanese Unexamined Patent Publication No. 2014-117566

In a gaming machine of a type in which the front door is closed with respect to the main body base while the protrusion on the back surface of the front door is inserted into the concave portion of the main body base as in Patent Document 1, the protrusion provided on the back surface of the front door. And, if the concave portion provided on the base of the main body is made larger, the front door is less likely to be misaligned with respect to the base of the main body (that is, it is less likely to be misaligned even when a load is applied). However, if the protrusions provided on the back surface of the front door and the concave portion provided on the base of the main body are made large (in both the front-rear direction and the width direction), when the front door is opened to eliminate ball clogging on the game board surface, etc. The game ball that has fallen from the surface of the game board easily enters the concave portion provided at the base of the main body. Then, when the game ball enters the concave portion of the main body base in this way, the front door cannot be closed with respect to the main body base. After scraping out the game ball that has entered, the front door must be closed again with respect to the base of the main body.

An object of the present invention is a conventional pachinko machine as described in Patent Document 1 (that is, a type of pachinko machine in which the front door is closed with respect to the main body base while the protrusion on the back surface of the front door is inserted into the concave portion of the main body base. The problem of the machine) has been solved, and the protrusion on the back of the front door and the concave part of the base of the main body are large, so the front door is very difficult to shift with respect to the base of the main body, and the game has entered the concave part. It is an object of the present invention to provide a practical gaming machine capable of easily ejecting a ball.

Among the present inventions, in the invention described in claim 1, a metal frame member is installed inside the machine frame, and a game board on which a winning device and an obstacle nail are installed is attached to the frame member. A game machine that is detachably attached and has a front door fitted with a glass plate attached to the frame member so as to cover the front surface of the game board so as to be openable on one side. A recess is formed in the lower portion, and a convex body is provided in the lower portion of the front door, and the front door fits the convex body into the recess and the convex body is formed on the bottom surface of the recess. The lower surface of the shape is supported and held in a closed state with respect to the frame member, and the bottom surface of the recess is inclined forward downward to the rear of the flat portion. The shape is such that the portions are continuously provided, and the difference between the depth of the concave portion of the frame member and the protruding length of the convex body of the front door is less than the diameter of the game ball. Is to be.

The invention according to claim 2 states that, in the invention according to claim 1, the front-rear width of the inclined portion of the bottom surface of the recess is a length of 1/2 or more of the diameter of the game ball. It is a feature.

The invention according to claim 3 is characterized in that, in the invention according to claim 1 or 2, the front of the flat portion of the bottom surface of the recess is inclined forward downward. It is a thing.

In the gaming machine according to claim 1, when the front door of the frame member is opened to clear the ball clogging, the gaming ball falls to the back surface of the gaming board surface and then falls to the frame member. If it is placed on the bottom surface of the recess, the front door cannot be closed even if the front door is closed with respect to the frame member without noticing the situation. Further, the gaming machine according to claim 1 attempts to close the front door with respect to the frame member (that is, by bringing the back surface of the front door closer to the surface of the frame member), thereby causing the bottom surface of the recess of the frame member. Since the game ball on the top is pushed to the back side of the recess by the convex body and reaches the inclined portion, when the front door is subsequently opened with respect to the frame member, the game ball reaching the inclined portion is reached. , Gravity rolls the inclined portion of the bottom surface of the concave portion, and with the rolling momentum, it passes through the flat portion and is discharged to the outside of the concave portion. Therefore, according to the gaming machine according to claim 1, it is possible to prevent a situation in which the gaming ball continues to stay on the bottom surface of the recess.

In the gaming machine according to claim 2, since the front-rear width of the inclined portion of the bottom surface of the recess is a length of 1/2 or more of the diameter of the gaming ball, after the gaming ball has flowed down to the back surface of the gaming board surface. When it falls and is placed on the bottom surface of the recess of the frame member, it is placed on the bottom surface of the recess when the front door is pressed against the frame member to close it and then opens without being completely closed. After the game ball is pushed up to the inclined portion, it is accurately discharged to the outside of the recess. Therefore, according to the gaming machine according to claim 2, it is possible to effectively prevent the situation where the gaming ball continues to stay on the bottom surface of the recess.

In the gaming machine according to claim 3, since the front of the flat portion on the bottom surface of the recess is inclined forward, the gaming ball is placed on the bottom surface of the recess of the frame member. When the door is opened after being pressed against the frame member to close it, the game ball on the bottom surface of the recess is pushed up to the inclined portion, then flows down, passes over the flat portion, and then rolls the front inclined portion. Since it moves, it is discharged to the outside of the recess with extremely high accuracy. Therefore, according to the gaming machine according to claim 3, it is possible to very effectively prevent the situation where the gaming ball continues to stay on the bottom surface of the recess.

<Explanation of the characteristic parts of pachinko machines>
FIG. 4 is a rear view (viewed from the rear) of the glass frame 11 provided on the back surface of the front door 3, and is at the lower end of the right side (right side when viewed from the front) of the glass frame 11. The fitting projection 21, which is a convex body for positioning the front door with respect to the mechanism plate (positioning up and down), is provided so as to project rearward from the plate surface of the glass frame 11. FIG. 5 is an enlarged view of the fitting protrusion 21, in which the lower portion of the fitting protrusion 21 has a rectangular parallelepiped shape that is long in the front-rear direction, and the fitting protrusion 21 is viewed from the upper surface of the rectangular parallelepiped engaging portion 22. Three vertical plate-shaped reinforcing pieces 23a to 23c are integrally provided. The length from the rear end to the front end of the engaging portion 22 is about 30 mm. Further, the left and right vertical side surfaces are orthogonal to the plate surface of the glass frame 11, and on those side surfaces, a substantially semi-cylindrical sliding auxiliary body 24a, which chamfers the peripheral edge of the rear end, 24b is projected.

Further, the bottom surface of the fitting projection 21 is in a state of being slightly inclined forward and downward with respect to the horizontal plane (a state of being inclined by about 5 °). Further, the tip surface of the fitting projection 21 (that is, the tip surface (rear surface) of the engaging portion 22) is provided parallel to the board surface of the glass frame 11. The portion connecting the bottom surface and the tip surface of the fitting protrusion 11 is in a chamfered state (R portion in FIG. 5).

On the other hand, as shown in FIG. 3, a fitting recess 31 which is a recess for fitting the fitting protrusion 21 of the glass frame 11 is formed at the lower end of the right side of the mechanism plate 5. ing. FIG. 6 is an enlarged view of the installation portion of the fitting recess 31, and the fitting recess 31 has a wide rectangular parallelepiped shape due to the left and right side plates 32a and 32b, the top plate 33, the bottom plate 34, and the back plate 35. The cavity is formed.

The left and right side plates 32a and 32b, the top plate 33, and the back plate 35 are integrally formed with the main body frame of the mechanism plate 5. Further, the left and right side plates 32a and 32b are provided vertically and vertically with respect to the board surface of the game board 4. Further, the back plate 35 is provided parallel and vertically with respect to the board surface of the game board 4.

Further, the bottom plate 34 is formed of metal in a strip shape having a constant width (about 30 mm width). A landing portion 36 having a constant width is formed near the front end edge, and a first inclined portion 37 having a constant front-rear width (about 12.0 mm) is formed behind the landing portion 36. .. Further, a horizontal portion 38 having a constant front-rear width (about 10.0 mm) is formed behind the first inclined portion 37, and a constant front-rear width (about 17.) is formed behind the horizontal portion 38. A second inclined portion 39 (0 mm) is formed. The landing portion 36 is vertically downward, and the first inclined portion 37 is in a state of being inclined forward downward so as to form an angle of about 20 ° with respect to the horizontal plane. Further, the second inclined portion 39 is in a state of being inclined forward downward so as to form an angle of about 7 ° with respect to the horizontal plane. Then, the bottom plate 34 formed as described above has a rear end inserted into a slit 40 formed at the lower end of the back plate with a portion near the rear end (a portion having a front-rear width of about 4.0 mm). It is screwed to the main body frame of the mechanism plate 5 by using the screw hole formed in the landing portion 36.

Further, on the right side of the fitting recess 31, a substantially rectangular parallelepiped storage case 41 for storing wiring and the like is installed, and the wall surface on the left side thereof functions as a side plate 32b on the right side of the fitting recess 31. There is. Further, the front surface of the storage case 41 is flush with the support plate 42 of the mechanism plate 5 to which the contact plate 36 of the bottom plate 34 is screwed. The depth of the fitting recess 31 (that is, the length from the front surface of the fitting portion 35 of the bottom plate 34 to the back plate) is about 35.0 mm. On the other hand, the side plate 32a on the left side of the fitting recess 31 is wider on the lower side than on the upper side. The lower end edge (upper end edge) is inclined at a position approximately 5.0 mm higher than the first inclined portion 37 of the bottom plate 34 at substantially the same angle as the first inclined portion 37 (that is, in a horizontal plane). On the other hand, it is tilted forward so as to form an angle of about 20 °).

<Action of pachinko machine>
In the pachinko machine 1, when the front door 3 is closed with respect to the mechanism plate 5 in a state where the game ball does not exist in the fitting recess 31, the fitting protrusion 21 on the back surface of the front door becomes the bottom surface. Is in contact with the bottom plate 34 of the fitting recess 31 and enters the inside of the fitting recess 31 (until the front end surface of the fitting portion 22 approaches the back plate 35). Then, when the fitting protrusion 21 on the back surface of the front door 3 enters the fitting recess 31 in this way, the fitting protrusion 21 is in a stable state in the fitting recess 31 (that is, the bottom surface of the fitting protrusion 21 is in a stable state. It is held in a large area in contact with the horizontal portion 38 of the bottom plate 34 of the fitting recess 31), and the vertical position and the left-right position of the front door 3 with respect to the mechanism plate 5 are accurately positioned. Therefore, the front door 3 can be closed with respect to the mechanism plate 5 (that is, the hook-shaped member 51 on the back surface of the front door 3 is engaged with the hole 52 of the mechanism plate 5). (See FIG. 7). Since the sliding auxiliary bodies 24a and 24b are projected on the side surfaces of the fitting protrusion 21, the fitting protrusion 21 fits very smoothly when the front door 3 is closed with respect to the mechanism plate 5. It enters the joint recess 31.

On the other hand, when the front door 3 is opened and the game board 4 is maintained (clearing the ball clogging, etc.), the game ball falls from the game area 10 of the game board 4 and the fitting recess 31 is formed. A situation may occur in which the game ball Y stays at the horizontal portion 38 of the bottom plate 34 (see FIG. 2). When such a situation occurs, if the game ball Y remains stationary on the horizontal portion 38 of the bottom plate 34 and the front door 3 is to be closed with respect to the mechanism plate 5, the fitting protrusion 21 protrudes. Difference between the length (length from the base end to the tip surface = about 30 mm) and the depth of the fitting recess 31 (the length from the front surface of the fitting portion 36 of the bottom plate 34 to the back plate 35 = about 35 mm) ( = Approximately 5.0 mm) is shorter than the diameter of one game ball (approximately 10 mm), so that the front door 3 is closed with respect to the mechanism plate 5 (that is, the hook-shaped member on the back surface of the front door 3). 51 cannot be engaged with the hole 52 of the mechanism plate 5).

In addition, as described above, when the game ball Y is stopped at the horizontal portion 38 of the bottom plate 34 and the front door 3 is to be closed with respect to the mechanism plate 5, the bottom plate 34 is horizontal as shown in FIG. The game ball Y on the portion 38 is pushed backward by the fitting protrusion 21 that has entered the fitting recess 31, and is pushed up to the top of the second inclined portion 39. Therefore, when an operator or the like who recognizes that the front door 3 cannot be closed with respect to the mechanism plate 5 opens the front door 3 again, the game ball Y pushed up to the top of the second inclined portion 39 is released. By its own weight, it flows down the upper surface of the second inclined portion 39, rolls on the upper surface of the horizontal portion 38 and the upper surface of the first inclined portion 37, is discharged from the fitting recess 31, and falls downward. Then, the operator or the like who has confirmed that the game ball Y has fallen can bring the front door 3 closer to the mechanism plate 5 and press it again to bring the front door 3 into a closed state with respect to the mechanism plate 5. It becomes.

<Effect of pachinko machine>
In the pachinko machine 1, as described above, the fitting recess 31 which is a recess is formed in the lower part of the mechanism plate 5 which is a frame member, and the fitting protrusion 21 which is a convex body is formed in the lower part of the front door 3. The mechanism plate is provided so that the front door 3 fits the fitting protrusion 21 into the fitting recess 31 and the bottom plate 34 of the fitting recess 31 supports the lower surface (bottom surface) of the fitting protrusion 21. It is configured to be held in a closed state with respect to 5, and the bottom plate 34 of the fitting recess 31 has a shape in which a second inclined portion 39 having an inclined front downward is continuously provided behind the horizontal portion 38. The difference between the depth of the fitting recess 31 and the protruding length of the fitting protrusion 21 is less than the diameter of the game ball Y.

Therefore, in the pachinko machine 1, when the front door 3 is opened with respect to the mechanism plate 5 to clear the ball clogging, the pachinko machine 1 falls after the game ball Y flows down to the back surface of the board surface of the game board 4. If the plate 5 is placed on the bottom plate 34 of the fitting recess 31, the front door 3 cannot be closed even if the front door 3 is closed with respect to the mechanism plate 5 without noticing the situation. Further, in the pachinko machine 1, by trying to close the front door 3 with respect to the mechanism plate 5 as described above (that is, by bringing the back surface of the front door 3 closer to the surface of the mechanism plate 5), the mechanism plate 5 The game ball Y resting on the bottom plate 34 of the fitting recess 31 is pushed to the back side of the fitting recess 31 by the fitting protrusion 21 and reaches the second inclined portion 39. Therefore, the front door 3 is subsequently opened. When the mechanical plate 5 is opened, the gaming ball Y reaching the second inclined portion 39 rolls on the second inclined portion 39 due to gravity, and passes through the horizontal portion 38 with the rolling momentum. Since the ball is discharged to the outside of the fitting recess 31, according to the pachinko machine 1, it is possible to prevent the game ball Y from continuing to stay on the bottom plate 34 of the fitting recess 31.

Further, in the pachinko machine 1, since the front-rear width of the second inclined portion 39 of the bottom plate 34 is a length of 1/2 or more of the diameter of the game ball Y, the game ball flows down to the back surface of the board surface of the game board 4. If the door 3 is dropped and placed on the bottom plate 34 of the fitting recess 31 of the mechanism plate 5, the front door 3 is pressed against the mechanism plate 5 to try to close it, and then the door 3 is opened (without being completely closed). At this time, the game ball Y resting on the bottom plate 34 of the fitting recess 31 is pushed up to the second inclined portion 39 and then is accurately discharged to the outside of the fitting recess 31. Therefore, according to the pachinko machine 1, it is possible to effectively prevent the game ball Y from continuing to stay on the bottom plate 34 of the fitting recess 31.

Further, in the pachinko machine 1, since the front of the horizontal portion 38 of the bottom plate 34 of the fitting recess 31 is inclined forward downward (that is, the first inclined portion 37 is formed), the game ball Y Is placed on the bottom plate 34 of the fitting recess 31 of the mechanism plate 5, and when the front door 3 is pressed against the mechanism plate 5 to close the door 3 and then opened, the bottom plate 34 of the fitting recess 31 is opened. Since the game ball on the top of the slingshot is pushed up by the second slanted portion 39, flows down, passes over the horizontal portion 38, and then rolls on the first inclined portion 37 in front, it reaches the outside of the fitting recess 31 with extremely high accuracy. It is discharged. Therefore, according to the pachinko machine 1, it is possible to very effectively prevent the game ball Y from staying on the bottom plate 34 of the fitting recess 31.
