That is, when the front cover member 7 is closed, the reinforcing rib portion 42 is positioned closer to the reinforcing rib portion 23 of the pachinko machine 1 according to the first embodiment than the back side wall surface of the front cover member 7. It is erected.

  Further, the groove 43 formed along the base end portion of the outer side wall portion 42B of the reinforcing rib portion 42 includes a vertical surface 43A substantially perpendicular to the surface portion of the front frame 3, and a back side direction of the vertical surface 43A (see FIG. 13, a flat inclined surface 43B that extends from the end edge portion to the outside direction (in the upper right direction in FIG. 13) from an edge portion. Moreover, the front side edge part of the front frame 3 of this inclined surface 43B is formed so that it may oppose in the back side end surface which opposes the peripheral surface part of the front frame 3 of the front cover member 7 as mentioned later ( (See FIG. 14).

Next, a schematic configuration of the reinforcing rib portion 42, the groove portion 43, and the guide rib portion 44 in a state where the front cover member 7 of the pachinko machine 41 is closed will be described with reference to FIG.
As shown in FIG. 14, when the front cover member 7 of the pachinko machine 41 is closed, the rear end surface portions (the lower end surface portions in FIG. 14) of the upper side portion and the left and right side portions of the front cover member 7 are The front frame 3 is brought into contact with the front peripheral surface (upper peripheral surface in FIG. 14), and the front surface of the front frame 3 is substantially covered by the front cover member 7 and is not visible from the front side on the player side. . Moreover, the front side edge part of the front frame 3 of the inclined surface 43B that forms the groove part 43 includes an inner side edge part and an outer side edge part of the rear side edge part of the upper side part and the left and right side parts of the front cover member 7. It is formed so as to oppose the position between. For example, as shown in FIG. 14B, the front side edge portion of the front frame 3 of the inclined surface 43B forming the groove portion 43 is the upper side portion of the front cover member 7 and the rear side end surface portion of the left and right side portions. It is formed at a position opposite to a position slightly outside the inner side edge. Further, the tip end portion (upper end surface portion in FIG. 14) of the reinforcing rib portion 42 extends to the vicinity of the back side surface of the front cover member 7.
Further, a guide rib portion 44 is provided in a substantially vertical outer direction over the entire length of the groove portion 43 (the lower side in FIG. It is formed in a straight line so as to protrude in the direction). When the front cover member 7 is closed, the upper end portion of the guide rib portion 44 is inserted into the groove portion 43 so as to be positioned in the vicinity of the inclined surface 43 </ b> B constituting the groove portion 43. .

  Thereby, for example, when a thin plastic plate (for example, a plastic plate having a thickness of about 0.5 mm) or the like is inserted from the gap between the side wall portion of the front cover member 7 and the front frame 3, the tip of the plastic plate The portion is in contact with the guide rib portion 44 of the front cover member 7 and is bent along the inclined surface 43B of the groove portion 43 in the back side direction (the lower direction in FIG. 14), and the vertical surface 43A and the inclined surface of the groove portion 43 are bent. It becomes a dead end at the back side of the groove part 43 formed by 43B, and it cannot get over the reinforcing rib part 42 and enter the game area direction (left direction in FIG. 14). Even if the height dimension of the guide rib portion 44 is low, the one-side surface portion of the plastic plate abuts against the guide rib portion 44 at the opening portion of the groove portion 43 (the upper end portion in FIG. 14B). Therefore, the front end portion of the plastic plate is bent in the back side direction (downward direction in FIG. 14) along the vertical surface 43A of the groove portion 43. Then, as shown in FIG. 14 (B), it enters the groove 43 in the direction of the arrow 45 and becomes a dead end on the back side of the groove 43 formed by the vertical surface 43A and the inclined surface 43B. Overcoming this, you will not be able to enter the game area direction (left direction in FIG. 14).

  Here, the vertical surface 43A functions as a first wall surface. The inclined surface 43B functions as a second wall surface.

  As described above, in the pachinko machine 41 according to the third embodiment, when the front cover member 7 is closed on the front surface portion of the synthetic resin front frame 3, the upper side portion of the inner wall surface of the front cover member 7 and Reinforcing ribs 42 are erected so as to face almost the entire length of the left-hand side. Further, an acute angle is formed at the base end portion of the outer side wall portion 42B of the reinforcing rib portion 42 from the vertical surface 43A substantially perpendicular to the surface portion of the front frame 3 and the rear side direction edge portion of the vertical surface 43A. A groove 43 composed of an inclined surface 43B extending in the outward direction is formed. Moreover, the front side edge part of the front frame 3 of this inclined surface 43B is a position between the inner side edge part and outer side edge part of the rear side edge part of the upper side part of the front cover member 7, and the left and right side parts. It is formed so as to face. Further, the guide rib portion 44 is linearly formed on the inner peripheral edge portion facing the groove portion 43 on the upper side portion and the left and right side portions of the front cover member 7 so as to protrude in a substantially vertical outer direction over the entire length of the groove portion 43. Is formed.

Accordingly, the rigidity of the front frame 3 made of synthetic resin can be reliably improved by the reinforcing rib portion 42, and when the front cover member 7 is closed, the reinforcing rib portion 42 and the groove portion 43 are formed on the front surface. Since it is covered with the cover member 7, it is possible to improve the appearance without generating a gap or the like in the front side peripheral portion of the pachinko machine 41.
Further, the front side edge portion of the front frame 3 of the inclined surface 43B of the groove portion 43 is between the inner side edge portion and the outer side edge portion of the rear side end portion of the upper side portion and the left and right side portions of the front cover member 7. Therefore, the reinforcing rib portion 42 can be erected closer to the inner side wall portion of the upper side portion and the left and right side portions of the front cover member 7. For this reason, even if a thin plastic plate or the like is inserted from the gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the reinforcing rib portion 42 is necessary for the plastic plate to reach the game area. After hitting the outer side wall portion, it bends substantially at a right angle, and further, it is necessary to get over the reinforcing rib portion 42, so that it is possible to make it difficult to enter a game area such as a thin plastic plate.
When a thin plastic plate or the like is inserted from the gap between the synthetic resin front frame 3 and the side end surface of the front cover member 7, the front end of the plastic plate is the front cover. Abutting on the guide rib portion 44 of the member 7, bent in the back side direction along the inclined surface 43 </ b> B of the groove portion 43, and a dead end on the back side of the groove portion 43 formed by the vertical surface 43 </ b> A and the inclined surface 43 </ b> B of the groove portion 43. Thus, it becomes impossible to get over the reinforcing rib portion 42 and enter the game area direction. Even if the height dimension of the guide rib portion 44 is low, the one side surface portion of the plastic plate abuts against the guide rib portion 44 at the opening portion of the groove portion 43, so that the back side direction along the vertical surface 43 A of the groove portion 43 It is forced to be bent into the groove portion 43 and is stopped at the acute bottom of the groove portion 43, making it very difficult to enter a game area such as a thin plastic plate.

(Fourth embodiment)
Next, a pachinko machine according to a fourth embodiment will be described with reference to FIG. In addition, the same code | symbol as the pachinko machine 1 which concerns on the said 1st Embodiment shows the same part as the pachinko machine 1 which concerns on the said 1st Embodiment, or an equivalent part.
The schematic configuration of the pachinko machine according to the fourth embodiment is substantially the same as the configuration of the pachinko machine 1 according to the first embodiment. However, the structure of the groove part of the pachinko machine according to the fourth embodiment is different from the structure of the groove part 24 of the pachinko machine 1 according to the first embodiment.

  As shown in FIG. 15, the schematic configuration of the pachinko machine 51 according to the fourth embodiment is substantially the same as that of the pachinko machine 1 according to the first embodiment (see FIGS. 1 to 3). However, as shown in FIG. 15, a groove portion 52 is formed at the base end portion of the outer side wall portion 23 </ b> A of the reinforcing rib portion 23. The groove portion 52 forms an acute angle from the vertical surface 52A substantially perpendicular to the surface portion of the front frame 3 and the edge of the back surface direction (the lower direction in FIG. 15) of the vertical surface 52A to form the outer direction (FIG. 15, a flat inclined surface 52 </ b> B extending in the right upper direction), and an arc portion 52 </ b> C having a substantially arc-shaped cross section formed at the edge of the front surface 3 of the front frame 3 of the inclined surface 52 </ b> B. It is configured. Further, the front side edge portion of the front frame 3 of the arc portion 52 </ b> C is formed so as to be located inside the inner side wall portion of the front cover member 7. Thereby, in the state where the front cover member 7 of the pachinko machine 51 is closed, the rear end surface portions (the lower end surface portions in FIG. 15) of the upper side portion and the left and right side portions of the front cover member 7 are the front frame 3. The front surface of the front frame 3 is almost covered with the front cover member 7 and is invisible from the front side on the player side, in contact with the front peripheral surface (in FIG. 15, the upper peripheral surface). Further, the front side edge portion of the front frame 3 of the arc portion 52C forming the groove portion 52 is formed at a position slightly inward of the upper side portion and the rear side end surface portion of the left and right side portions of the front cover member 7. Yes. Further, the tip end portion (upper end surface portion in FIG. 15) of the reinforcing rib portion 23 extends to the vicinity of the back side surface of the front cover member 7.

Therefore, the rigidity of the front frame 3 made of synthetic resin can be reliably improved by the reinforcing rib portion 23, and when the front cover member 7 is closed, the reinforcing rib portion 23 and the groove portion 52 are formed on the front surface. Since it is covered with the cover member 7, it is possible to improve the appearance without generating a gap or the like in the front side peripheral portion of the pachinko machine 51.
Further, even if a thin plastic plate or the like is inserted from the gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, in order to reach the game area, the plastic plate After hitting the outer side wall portion, it bends at a substantially right angle, and further, it is necessary to get over the reinforcing rib portion 23, so that it is possible to make it very difficult to enter a game area such as a thin plastic plate. Further, when a thin plastic plate or the like is inserted from the gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the plastic plate hits the outer side wall portion 23 </ b> A of the reinforcing rib portion 23. Further, it becomes easy to bend in the rear side direction of the pachinko machine 51 (in the direction of the arrow 53) along the arc portion 52C, and along the vertical surface 52A of the groove portion 52 formed along the base end portion of the outer side wall portion 23A. The possibility of entering the groove portion 52 along the inclined surface 52B can be increased, and when entering the groove portion 52, the dead end is reached and the entry into the game area such as a thin plastic plate is further extremely reduced. It becomes possible to make it difficult.

  Here, the vertical surface 52A functions as a first wall surface. Further, the inclined surface 52B and the circular arc portion 52C constitute a second wall surface.

(Fifth embodiment)
Next, a pachinko machine according to a fifth embodiment will be described with reference to FIG. In addition, the same code | symbol as the pachinko machine 31 which concerns on the said 2nd Embodiment shows the same part as the pachinko machine 31 which concerns on the said 2nd Embodiment, or an equivalent part.
The schematic configuration of the pachinko machine according to the fifth embodiment is substantially the same as the configuration of the pachinko machine 31 according to the second embodiment. However, the configuration of the groove portion of the pachinko machine according to the fifth embodiment is different from the configuration of the groove portion 33 of the pachinko machine 31 according to the second embodiment.

  As shown in FIG. 16, the schematic configuration of the pachinko machine 61 according to the fifth embodiment is substantially the same as that of the pachinko machine 31 according to the second embodiment (see FIGS. 6 and 7). However, as shown in FIG. 16, the groove portion 62 formed along the base end portion of the outer side wall portion 32B of the reinforcing rib portion 32 has a vertical surface 62A substantially perpendicular to the surface portion of the front frame 3, and the vertical surface. An inclined surface 62B having a substantially arc-shaped cross section that forms an acute angle from the edge of the rear side direction (lower direction in FIG. 16) of 62A and extends outward (rightward upward direction in FIG. 16). Has been. Further, the front side edge portion of the front frame 3 of the inclined surface 62B is formed to face the back side end surface of the front cover member 7 that faces the peripheral surface portion of the front frame 3. Thereby, in a state where the front cover member 7 of the pachinko machine 61 is closed, the rear side end surface portion (the lower end surface portion in FIG. 16) of the upper side portion and the left and right side portions of the front cover member 7 is the front frame 3. Abutting against the front peripheral surface (in FIG. 16, the upper peripheral surface), the front surface of the front frame 3 is almost covered with the front cover member 7 and is not visible from the front side on the player side. Further, the front side edge portion of the front frame 3 of the inclined surface 62B forming the groove portion 62 is slightly outside the inner side edge portion of the rear side end surface portion of the upper side portion and the left and right side portions of the front cover member 7. It is formed at a position opposite to the position. Further, the distal end portion (upper end surface portion in FIG. 16) of the reinforcing rib portion 32 extends to the vicinity of the back side surface of the front cover member 7.

Accordingly, the rigidity of the front frame 3 made of synthetic resin can be reliably improved by the reinforcing rib portion 32, and when the front cover member 7 is closed, the reinforcing rib portion 32 is used as the front cover member 7. Therefore, the appearance of the pachinko machine 61 can be improved without generating a gap or the like in the front side peripheral edge portion.
Further, the front side edge portion of the front frame 3 of the inclined surface 62B of the groove portion 62 is between the inner side edge portion and the outer side edge portion of the rear side end surface portion of the upper side portion and the left and right side portions of the front cover member 7. Therefore, the reinforcing rib portion 32 can be erected closer to the inner side wall portion of the upper side portion and the left and right side portions of the front cover member 7. For this reason, even if a thin plastic plate or the like is inserted from the gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the reinforcing rib portion 32 is necessary for the plastic plate to reach the game area. After hitting the outer side wall portion, it bends substantially at a right angle, and further, it is necessary to get over the reinforcing rib portion 32, so that it is difficult to enter the game area such as a thin plastic plate.
Further, when a thin plastic plate or the like is inserted from the gap between the synthetic resin front frame 3 and the side end surface of the front cover member 7, the tip of the plastic plate hits the vertical surface 62 </ b> A of the groove 62. At this time, the thin plastic plate that has entered the groove 62 is easier to bend in the back side direction of the pachinko machine 61 (in the direction of the arrow 63), and the vertical surface 62A is in any position over the entire length of the groove 62. In the state of being pressed so as to be pressed against the inclined surface 62B having a substantially arc-shaped cross section at the back edge, a dead end is reached at the acute bottom of the groove 62, making it extremely difficult to enter a gaming area such as a thin plastic plate. It becomes possible to do.

  Here, the vertical surface 62A functions as a first wall surface. The inclined surface 62B functions as a second wall surface.

(Sixth embodiment)
Next, a pachinko machine according to a sixth embodiment will be described with reference to FIG. In addition, the same code | symbol as the pachinko machine 41 concerning the said 3rd Embodiment shows the same part as the pachinko machine 41 concerning the said 3rd Embodiment, or an equivalent part.
The schematic configuration of the pachinko machine according to the sixth embodiment is substantially the same as the configuration of the pachinko machine 41 according to the third embodiment. However, the configuration of the groove portion of the pachinko machine according to the sixth embodiment is different from the configuration of the groove portion 43 of the pachinko machine 41 according to the third embodiment.

As shown in FIG. 17, the schematic configuration of the pachinko machine 71 according to the sixth embodiment is substantially the same as the pachinko machine 41 according to the third embodiment (see FIGS. 10 to 12). However, as shown in FIG. 16, the groove portion 72 formed along the base end portion of the outer side wall portion 42B of the reinforcing rib portion 42 has a vertical surface 72A substantially perpendicular to the surface portion of the front frame 3, and the vertical surface. An inclined surface 72B having a substantially arc-shaped cross section extending from the edge of the back side of the pachinko machine 71 of 72A (the lower direction in FIG. 17) to the outer side (upward to the right in FIG. 17). And is composed of. Further, the front side edge portion of the front frame 3 of the inclined surface 72 </ b> B is formed so as to face the back side end surface of the front cover member 7 that faces the peripheral surface portion of the front frame 3. Thereby, in the state where the front cover member 7 of the pachinko machine 71 is closed, the rear end surface portions (the lower end surface portions in FIG. 17) of the upper side portion and the left and right side portions of the front cover member 7 are the front frame 3. Abutting against the front peripheral surface (in FIG. 17, the upper peripheral surface), the front surface of the front frame 3 is almost covered with the front cover member 7 and is not visible from the front side on the player side. Further, the front side edge portion of the front frame 3 of the inclined surface 72B forming the groove portion 72 is slightly outward from the inner side edge portion of the rear side edge portion of the upper side portion and the left and right side portions of the front cover member 7. It is formed at a position opposite to the position. Further, the tip end portion (upper end surface portion in FIG. 17) of the reinforcing rib portion 42 extends to the vicinity of the back side surface of the front cover member 7.
Further, the guide rib portion 44 is provided in the substantially vertical outer direction (lower side in FIG. 17) over the entire length of the groove portion 72 on the inner peripheral edge portion facing the groove portion 72 on the upper side portion and the left and right side portions on the front cover member 7. It is formed in a straight line so as to protrude in the direction). When the front cover member 7 is closed, the upper end portion of the guide rib portion 44 is inserted into the groove portion 72 so as to be positioned in the vicinity of the inclined surface 72 </ b> B constituting the groove portion 72. .

Therefore, the rigidity of the front frame 3 made of synthetic resin can be reliably improved by the reinforcing rib portion 42, and when the front cover member 7 is closed, the reinforcing rib portion 42 and the groove portion 72 are formed on the front surface. Since it is covered with the cover member 7, it is possible to improve the appearance without generating a gap or the like in the front side peripheral portion of the pachinko machine 71.
Further, the front-side edge portion of the front frame 3 of the inclined surface 72B of the groove portion 72 is between the inner side edge portion and the outer side edge portion of the rear side edge portion of the upper side portion and the left and right side portions of the front cover member 7. Therefore, the reinforcing rib portion 42 can be erected closer to the inner side wall portion of the upper side portion and the left and right side portions of the front cover member 7. For this reason, even if a thin plastic plate or the like is inserted from the gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the reinforcing rib portion 42 is necessary for the plastic plate to reach the game area. After hitting the outer side wall portion, it bends substantially at a right angle, and further, it is necessary to get over the reinforcing rib portion 42, so that it is possible to make it difficult to enter a game area such as a thin plastic plate.
When a thin plastic plate or the like is inserted from the gap between the synthetic resin front frame 3 and the side end surface of the front cover member 7, the front end of the plastic plate is the front cover. Abutting on the guide rib portion 44 of the member 7, the groove portion 72 is forcibly bent (in the direction of arrow 73) along the inclined surface 72 </ b> B having a substantially arc-shaped cross section. When the plastic plate further enters, it is pressed so as to be pressed against the inclined surface 72B having a substantially arc-shaped cross section at the rear end edge of the vertical surface 72A at any position over the entire length of the groove 72. In this state, a dead end is reached at the acute bottom of the groove 72, and it becomes impossible to get over the reinforcing rib 42 and enter the game area. Further, even if the height dimension of the guide rib portion 44 is low, the one-side surface portion of the plastic plate abuts against the guide rib portion 44 at the opening portion of the groove portion 72, so that the back side direction along the vertical surface 72 A of the groove portion 72 It is forced to be bent into the groove portion 72 and is brought to a dead end at the acute bottom portion of the groove portion 72, making it extremely difficult to enter a game area such as a thin plastic plate.

  Here, the vertical surface 72A functions as a first wall surface. The inclined surface 72B functions as a second wall surface.

Next, a pachinko machine according to a seventh embodiment will be described with reference to FIG. In addition, the same code | symbol as the pachinko machine 1 which concerns on the said 1st Embodiment shows the same part as the pachinko machine 1 which concerns on the said 1st Embodiment, or an equivalent part.
The schematic configuration of the pachinko machine according to the seventh embodiment is substantially the same as the configuration of the pachinko machine 1 according to the first embodiment. However, the configuration of the groove portion of the pachinko machine according to the seventh embodiment is different from the configuration of the groove portion 24 of the pachinko machine 1 according to the first embodiment.

  As shown in FIG. 18, the schematic configuration of the pachinko machine 81 according to the seventh embodiment is substantially the same as that of the pachinko machine 1 according to the first embodiment (see FIGS. 1 to 3). However, as shown in FIG. 18, a groove portion 82 is formed at the base end portion of the outer side wall portion 23 </ b> A of the reinforcing rib portion 23. The groove 82 has a wall surface 82A inclined inward (leftward direction in FIG. 18) from a vertical plane substantially perpendicular to the surface portion of the front frame 3, and a rear side direction (lower direction in FIG. 18) of the wall surface 82A. ) A flat inclined surface 82B that forms an acute angle from the end edge portion and extends outward (in the upper right direction in FIG. 18). Further, the front side edge portion of the front frame 3 of the inclined surface 82 </ b> B is formed so as to be located inside the inner side wall portion of the front cover member 7. Thereby, in the state where the front cover member 7 of the pachinko machine 81 is closed, the rear end surface portions (lower end surface portions in FIG. 18) of the upper side portion and the left and right side portions of the front cover member 7 are the front frame 3. Abutting against the front peripheral surface (in FIG. 18, the upper peripheral surface), the front portion of the front frame 3 is almost covered by the front cover member 7 and is not visible from the front side on the player side. Further, the front side edge portion of the front frame 3 of the inclined surface 82B forming the groove portion 82 is formed at a position slightly inward of the upper side portion and the rear side end surface portion of the left and right side portions of the front cover member 7. Yes. Further, the distal end portion (upper end surface portion in FIG. 18) of the reinforcing rib portion 23 extends to the vicinity of the back side surface of the front cover member 7.

Therefore, the rigidity of the front frame 3 made of synthetic resin can be reliably improved by the reinforcing rib portion 23, and when the front cover member 7 is closed, the reinforcing rib portion 23 and the groove portion 82 are formed on the front surface. Since it is covered with the cover member 7, it is possible to improve the appearance without generating a gap or the like in the front side peripheral portion of the pachinko machine 81.
Further, even if a thin plastic plate or the like is inserted from the gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, in order to reach the game area, the plastic plate After hitting the outer side wall portion, it bends at a substantially right angle, and further, it is necessary to get over the reinforcing rib portion 23, so that it is possible to make it very difficult to enter a game area such as a thin plastic plate. Further, when a thin plastic plate or the like is inserted from a gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the plastic plate hits the outer side wall portion 23 </ b> A of the reinforcing rib portion 23 and hits the pachinko machine 81. When bent in the rear side direction (in the direction of arrow 83), the groove portion 82 extends along the inclined surface 82B along the wall surface 82A of the groove portion 82 formed along the base end portion of the outer side wall portion 23A. Since it enters, it becomes a dead end at the sharp bottom of the groove 82, and it becomes possible to make it very difficult to enter a game area such as a thin plastic plate.

  Here, the wall surface 82A functions as a first wall surface. Further, the inclined surface 82B functions as a second wall surface.

In addition, you may form the circular arc part (for example, it corresponds to the circular arc part 52C in FIG. 15) in the edge part of the surface side direction of the front frame 3 of the inclined surface 82B. Thus, even when a thin plastic plate or the like is inserted from the gap between the front frame 3 and the side end surface of the front cover member 7, the plastic plate is inclined when it hits the outer side wall portion 23 </ b> A of the reinforcing rib portion 23. It becomes easy to bend in the rear direction of the pachinko machine 81 (in the direction of the arrow 83) along the arc portion of the edge of the front frame 3 of the front frame 3 of the surface 82B, and along the base end portion of the outer side wall portion 23A. The possibility of entering the groove portion 82 along the inclined surface 82B along the wall surface 82A of the groove portion 82 to be formed can be increased, and when entering the groove portion 82, a dead end is formed, and a thin plastic is formed. It becomes possible to make it very difficult to enter a game area such as a board.
Here, the wall surface 82A functions as a first wall surface. In addition, the inclined surface 82B and an arc portion having a substantially arc-shaped cross section at the edge of the inclined surface 82B in the surface side direction of the front frame 3 form a second wall surface.

In addition, the same code | symbol as the pachinko machine 31 which concerns on the said 2nd Embodiment shows the same part as the pachinko machine 31 which concerns on the said 2nd Embodiment, or an equivalent part.
The schematic configuration of the pachinko machine according to the eighth embodiment is substantially the same as the configuration of the pachinko machine 31 according to the second embodiment. However, the configuration of the groove portion of the pachinko machine according to the eighth embodiment is different from the configuration of the groove portion 33 of the pachinko machine 31 according to the second embodiment.

  As shown in FIG. 19, the schematic configuration of the pachinko machine 91 according to the eighth embodiment is substantially the same as that of the pachinko machine 31 according to the second embodiment (see FIGS. 6 and 7). However, as shown in FIG. 19, the groove 92 formed along the base end portion of the outer side wall portion 32 </ b> B of the reinforcing rib portion 32 is inward of the vertical plane substantially perpendicular to the surface portion of the front frame 3 (see FIG. 19). 19, the wall surface 92 </ b> A inclined to the left side) and the edge of the back surface direction (the lower direction in FIG. 19) of the wall surface 92 </ b> A to form an acute angle in the outer direction (the upper right side in FIG. 19). And a planar inclined surface 92B that extends. Further, the front side edge portion of the front frame 3 of the inclined surface 92B is formed so as to face the back side end surface of the front cover member 7 that faces the peripheral surface portion of the front frame 3. Thereby, in the state where the front cover member 7 of the pachinko machine 91 is closed, the rear side end surfaces (the lower side end surfaces in FIG. 19) of the upper side and the left and right side sides of the front cover member 7 are the front frame 3. The front side surface of the front frame 3 is almost covered with the front cover member 7 and is not visible from the front side on the player side. Further, the front side edge portion of the front frame 3 of the inclined surface 92B forming the groove portion 92 is slightly outward from the inner side edge portion of the rear side end portion of the upper side portion and the left and right side portions of the front cover member 7. It is formed at a position opposite to the position. Further, the front end portion (upper end surface portion in FIG. 19) of the reinforcing rib portion 32 extends to the vicinity of the back side surface of the front cover member 7.

Accordingly, the rigidity of the front frame 3 made of synthetic resin can be reliably improved by the reinforcing rib portion 32, and when the front cover member 7 is closed, the reinforcing rib portion 32 is used as the front cover member 7. Therefore, the appearance of the pachinko machine 91 can be improved without generating a gap or the like in the peripheral portion on the front surface side.
Further, the front side edge portion of the front frame 3 of the inclined surface 92B of the groove portion 92 is between the inner side edge portion and the outer side edge portion of the rear side edge portion of the upper side portion and the left and right side portions of the front cover member 7. Therefore, the reinforcing rib portion 32 can be erected closer to the inner side wall portion of the upper side portion and the left and right side portions of the front cover member 7. For this reason, even if a thin plastic plate or the like is inserted from the gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the reinforcing rib portion 32 is necessary for the plastic plate to reach the game area. After hitting the outer side wall portion, it bends substantially at a right angle, and further, it is necessary to get over the reinforcing rib portion 32, so that it is difficult to enter the game area such as a thin plastic plate.
Further, when a thin plastic plate or the like is inserted from the gap between the synthetic resin front frame 3 and the side end surface of the front cover member 7, the tip of the plastic plate hits the wall surface 92 </ b> A of the groove 92. Furthermore, it becomes easier to bend in the direction of the back side of the pachinko machine 91 (in the direction of the arrow 93). When the plastic plate hits the outer side wall portion 23A of the reinforcing rib portion 23 and bends in the rear direction of the pachinko machine 91 (in the direction of the arrow 93), the plastic plate is inclined along the wall surface 92A of the groove portion 92. Since it enters into the groove part 92 along the surface 92B, it becomes a dead end at the acute bottom part of the groove part 92, and it becomes possible to make it very difficult to enter into a game area such as a thin plastic plate.

  Here, the vertical surface 92A functions as a first wall surface. The inclined surface 92B functions as a second wall surface.

The flat inclined surface 92B may be formed as an inclined surface having a substantially arcuate cross section protruding toward the wall surface 92A (for example, corresponding to the inclined surface 62B in FIG. 16). Thereby, when a thin plastic plate or the like is inserted from the gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the tip of the plastic plate hits the wall surface 92A of the groove 92. At this time, it becomes easier to bend in the back side direction of the pachinko machine 91 (in the direction of the arrow 93), and the thin plastic plate that has entered the groove portion 92 is formed on the wall surface 92A at any position over the entire length of the groove portion 92. A dead end is formed at the acute bottom of the groove 92 while being pressed against an inclined surface having a substantially arc-shaped cross section at the rear edge, making it extremely difficult to enter a game area such as a thin plastic plate. Is possible.
Here, the wall surface 92A functions as a first wall surface. Further, the inclined surface having a substantially arc-shaped cross-section projecting toward the wall surface 92A functions as a second wall surface.

(Ninth embodiment)
Next, a pachinko machine according to a ninth embodiment will be described with reference to FIG. In addition, the same code | symbol as the pachinko machine 41 concerning the said 3rd Embodiment shows the same part as the pachinko machine 41 concerning the said 3rd Embodiment, or an equivalent part.
The schematic configuration of the pachinko machine according to the ninth embodiment is substantially the same as the configuration of the pachinko machine 41 according to the third embodiment. However, the configuration of the groove portion of the pachinko machine according to the ninth embodiment is different from the configuration of the groove portion 43 of the pachinko machine 41 according to the third embodiment.

As shown in FIG. 20, the schematic configuration of the pachinko machine 101 according to the ninth embodiment is substantially the same as that of the pachinko machine 41 according to the third embodiment (see FIGS. 10 to 12). However, as shown in FIG. 20, the groove 102 formed along the base end portion of the outer side wall portion 42 </ b> B of the reinforcing rib portion 42 is inward of the vertical plane substantially perpendicular to the surface portion of the front frame 3 (see FIG. 20). 20, the wall surface 102 </ b> A inclined toward the left side) and the edge of the back side direction (the lower direction in FIG. 20) of the wall surface 102 </ b> A to form an acute angle in the outer direction (the upper right direction in FIG. 20). And a planar inclined surface 102B that extends. Further, the front side edge portion of the front frame 3 of the inclined surface 102B is formed to face the back side end surface of the front cover member 7 that faces the peripheral surface portion of the front frame 3. Thereby, in the state where the front cover member 7 of the pachinko machine 101 is closed, the rear end surface portions (lower end surface portions in FIG. 20) of the upper side portion and the left and right side portions of the front cover member 7 are the front frame 3. The front surface of the front frame 3 is substantially covered with the front cover member 7 and is invisible from the front side on the player side, being in contact with the front peripheral surface (in FIG. 20, the upper peripheral surface). Further, the front side edge portion of the front frame 3 of the inclined surface 102B forming the groove portion 102 is slightly outward from the inner side edge portion of the rear side end portion of the upper side portion and the left and right side portions of the front cover member 7. It is formed at a position opposite to the position. Further, the tip end portion (upper end surface portion in FIG. 20) of the reinforcing rib portion 42 extends to the vicinity of the back side surface of the front cover member 7.
Further, on the inner peripheral edge facing the groove 102 on the upper side and the left and right sides of the front cover member 7, a guide rib portion 44 extends in a substantially vertical outer direction over the entire length of the groove 102 (the lower side in FIG. 20). It is formed in a straight line so as to protrude in the direction). When the front cover member 7 is closed, the upper end portion of the guide rib portion 44 is inserted into the groove portion 102 so as to be positioned in the vicinity of the inclined surface 102 </ b> B constituting the groove portion 102. .

Therefore, the rigidity of the front frame 3 made of synthetic resin can be reliably improved by the reinforcing rib portion 42, and when the front cover member 7 is closed, the reinforcing rib portion 42 and the groove portion 102 are formed on the front surface. Since it is covered with the cover member 7, the appearance can be improved without generating a gap or the like in the front side peripheral edge portion of the pachinko machine 101.
Further, the front side edge portion of the front frame 3 of the inclined surface 102B of the groove portion 102 is between the inner side edge portion and the outer side edge portion of the rear side edge portion of the upper side portion and the left and right side portions of the front cover member 7. Therefore, the reinforcing rib portion 42 can be erected closer to the inner side wall portion of the upper side portion and the left and right side portions of the front cover member 7. For this reason, even if a thin plastic plate or the like is inserted from the gap between the front frame 3 made of synthetic resin and the side end surface of the front cover member 7, the reinforcing rib portion 42 is necessary for the plastic plate to reach the game area. After hitting the outer side wall portion, it bends substantially at a right angle, and further, it is necessary to get over the reinforcing rib portion 42, so that it is possible to make it difficult to enter a game area such as a thin plastic plate.
When a thin plastic plate or the like is inserted from the gap between the synthetic resin front frame 3 and the side end surface of the front cover member 7, the front end of the plastic plate is the front cover. It abuts on the guide rib portion 44 of the member 7 and is forcibly bent along the inclined surface 102B of the groove portion 102 (in the direction of the arrow 103). When the plastic plate further enters, the groove portion is pressed so as to be pressed against the inclined surface 102B at the inner edge of the wall surface 102A at any position over the entire length of the groove portion 102. A dead end is formed at the acute bottom portion of 102, and the reinforcement rib portion 42 is overcome and cannot enter the game area direction. Even if the height dimension of the guide rib portion 44 is low, the one-side surface portion of the plastic plate abuts against the guide rib portion 44 at the opening portion of the groove portion 102, so that the back side direction along the wall surface 102 </ b> A of the groove portion 102 is provided. It is forced to enter the groove 102 while being bent, and reaches a dead end at the acute bottom of the groove 102, making it very difficult to enter a game area such as a thin plastic plate.

  Here, the wall surface 102A functions as a first wall surface. The inclined surface 102B functions as a second wall surface.

The flat inclined surface 102B may be formed as an inclined surface having a substantially arcuate cross section projecting toward the wall surface 102A (for example, corresponding to the inclined surface 72B in FIG. 17). Thus, when a thin plastic plate or the like is inserted from the gap between the synthetic resin front frame 3 and the side end surface of the front cover member 7, the leading end portion of the plastic plate is the guide rib portion of the front cover member 7. 44, it becomes easier to bend in the direction of the back side of the pachinko machine 101 (in the direction of the arrow 103), and the thin plastic plate that has entered the groove 102 is located at any position over the entire length of the groove 102. The dead end at the acute bottom of the groove 102 is pressed against the inclined surface having a substantially arc-shaped cross section at the rear edge of the wall surface 102A, and extremely penetrates into a game area such as a thin plastic plate. It becomes possible to make it difficult.
Here, the wall surface 102A functions as a first wall surface. Further, the inclined surface having a substantially arc-shaped cross-section protruding toward the wall surface 102A functions as the second wall surface.

Further, the present invention is not limited to the first to ninth embodiments, and various improvements and modifications can be made without departing from the gist of the present invention.
For example, in the first to ninth embodiments, the reinforcing rib portions 23, 32, and 42 and the groove portions 24 to 102 are formed in a shape in which a portion facing the upper hinge 4 is partially cut off. Further, it may be formed in a continuous shape in accordance with the shape of the inner side wall portion of the front cover member 7. Thus, even when a thin plastic plate (for example, a plastic plate having a thickness of about 0.5 mm) is inserted through the gap between the side wall portion of the front cover member 7 near the upper hinge 4 and the front frame 3, the plastic The plate or the like comes into contact with each of the reinforcing rib portions 23, 32, and 42 and then enters each of the groove portions 24 to 102 and becomes a dead end on the back side, and the side wall portion and the front frame of the front cover member 7 near the upper hinge 4. Intrusion in the direction of the game area from the gap with 3 can be made more difficult.
