The left and right rails 28 and 29 are made of polycarbonate, and extend over substantially the entire length thereof in the order from the back as viewed from the back, from the back to the first piece 30, the second piece 31, and the third piece 32.
Are integrally formed so as to protrude inward. Also, the hooks 33, 33,.
Are integrally formed so as to protrude outward in a state where they are arranged so as to correspond to the mounting holes 21, 21,....

On the other hand, the lower rail 27 also includes left and right rails 28,
It is formed in the same manner as 29, but differs in that the front side of the periphery of the central hook portion 33 when viewed from behind is a separate reinforcing portion 34 (FIG. 6 etc.). The reinforcing portion 34 is made of a material having excellent fatigue resistance and abrasion resistance, for example, an acetal resin, and is fitted from below into a part of the third piece 32 and a long concave portion formed below the second piece 31. Hook piece 36 and hook 3
3 has a shape including a projecting portion 35 for closing a hole of the second piece 31 necessary for the projecting molding and a half of the central hook portion 33.

Further, a receiving hole 40 is formed at the lower end of the right rail 29. At the right end of the lower rail 27, a pressing projection 41 having substantially the same size as the receiving hole 40 is provided, and at the left end, a receiving piece 42 having a width slightly smaller than that of the lower rail 27 is provided. In addition, left rail 28
The lower end is formed as a pressing portion 43 by forming a recess having substantially the same size as the receiving piece 42.

Then, the right rail 29 is locked by pulling down the hook 33 in a state where it is inserted into the upper part of the corresponding mounting hole 21 (FIG. 3). When pulled downward, the hook 33 is located at a narrow portion in the front-rear direction of the mounting hole 21 and is in contact with the lower end. The lower end of the right rail 29 is in contact with the lower rail rib 17. Similarly, the lower rail 27 is pulled to the right and attached (FIG. 4). When the lower rail 27 is pulled to the right, the pressing projection 41 at the right end
Is inserted into the receiving hole 40 of the right rail 19 and the lower rail 2
7 and the receiving piece 42 located at the escape portion 24 moves to a position just rightward from the escape portion 24. Similarly, the left rail 28 is pulled down and mounted. Pressing part 4 at lower end of left rail 28
3 is the outer periphery of the receiving piece 42 of the lower rail 27 and the receiving piece 4
2 touches the end face on which it stands and engages with it.

In addition, a left peripheral standing portion of the base 12;
A closing member 45 having a U-shaped cross section which is engaged with the left rail rib 18 when the front frame 7 is locked to the main body frame 3 in a closed state.
Are attached so as to partially insert the upper and lower through holes 23 and 25 and surround the closing member rib 46. At this time, the left side surface as viewed from the back of the closing member rib 46 and each small rib 52 are pressed against the closing member 45. Further, hooks 44 (FIG. 5) projecting rightward from the back of the closing member 45 engage with the hooks 47.

An inverted concave fixing member 50 having a locking claw 48 on the inner side and an entry piece 49 on the right side is straddled over the closing member 45 and the upper end thereof is locked by the locking claw 48. At the same time, the entry piece 49 enters the entire upper side of the uppermost mounting hole 21 and is engaged with the upper side of the horizontal rib 22 while slightly pressed against the uppermost hook portion 33 of the left rail 28 ( 7 and 8). Engagement of the fixing member 50 and each of the rails 27-2
Due to the combination of the components 9, the rails 27 to 29 are fixed integrally with the front frame 7, that is, after being attached, so as not to move relative to the front frame 7 even when the glass plate is taken in and out. . In this state, the glass plate 26 having a thickness of about 3 mm is placed between the first piece 30 and the second piece 31 and between the second piece 31 and the third piece 32 of each of the rails 27 to 29 (in each case). (Slightly larger than the thickness of the glass plate 26)
Is inserted from above.

In such a pachinko machine 1, each of the rail ribs 17 to 17 on the back surface of the front frame 7 provided on the side edge to be openable and closable.
Since the corresponding rails 27 to 29 are attached to the hook 19 by hooking the hooks 33, the support structure of the glass plates 26, 26 can be formed or removed with one touch. Also, rails 27-29 and base 1
Even if 2 and the like are formed of a synthetic resin, the glass plates 26 and 26 can be sufficiently supported, and the entire front frame 7 can be made lightweight. Thus, the front frame 7 can be made easy to handle during manufacturing or maintenance.

Further, the ends of the plurality of rails and the ends of the adjacent rails are combined to form the right rail 29 and the lower rail 2.
7 and the left rail 28 are installed in this order.
All the rails 27 to 29 are fixed only by engaging the fixing member 50 in the vicinity of the upper end of the rail 8, so that the fixing work for completing the mounting is simplified, and the rails 27 to 2
9 is integrated with the front frame 7 after installation, and is advantageous in strength in spite of its simple configuration. Here, since the closing member 45 which is a part of the lock mechanism is also attached by the fixing member 50 at the same time, the handling of the front frame 7 is further simplified.

Further, since the lower rail 27 is provided with a reinforcing portion 34 having excellent fatigue resistance and abrasion resistance, even if a game ball collides, cracking or chipping can be prevented. Here, during the game with the pachinko machine 1, the game ball that does not win the prize device reaches the lowermost portion (located substantially at the center in the left-right direction) of the circular game area and is viewed from the front for collection. Each of the rails is guided to the back, and falls at the back as viewed from the front of the lower portion of the front frame 7, while the winning game ball falls at the back as viewed from the front. 2
Of 7-29, there is a possibility of colliding with the game ball,
It is a central portion on the near side when viewed from the back of the lower rail 27,
Therefore, the reinforcing portion 34 occupies a necessary and sufficient position and range. Further, since the reinforcing portion 34 closes a hole provided when the central hook portion 33 is formed, the strength can be improved, and a fraudulent act can be prevented by eliminating a gap for a tool to enter.

Since each of the rail ribs 17 to 19 is integrally formed in a U shape surrounding three sides at the periphery,
The entire front frame 7 can resist warping or twisting, so that the front frame 7 can be formed with high strength, and since there is no need to extend a rib, the front frame 7 can be easily formed. Further, the mounting strength of each of the rails 27 to 29 can be improved. Further, since the closing member 45 is fixed by the pressure contact of the closing member rib 46 and the engagement of the hook piece 44 with the hook portion 47, the closing member 45 can be fixed to the front frame 7 with sufficient strength. In addition, it is possible to prevent a situation where the front frame 7 is opened despite being locked.

[Second Embodiment] The pachinko machine according to the second embodiment is the same as the pachinko machine of the first embodiment except for the back surface of the base 58 of the front frame 57 shown in FIG. Hereinafter, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description will be focused on the differences.

The front frame 57 of the second embodiment is the same as the first frame.
All the rails of the embodiment are integrally formed with the respective rail ribs, that is, the lower, left, and right rails 60, 61, and 6 surround three sides other than the upper side of the base 58.
2 is erected integrally with the base 58. Each of the rails 60 to 62 includes a first piece 63, a second piece 64, and a third piece 65. In addition, the fixing member 50 fixes only the closing member 45.

In the pachinko machine of the second embodiment, the first piece 63, the second piece 64,
Since the rails 60 to 62 having the third piece 65 are integrally formed, the strength can be sufficiently increased, and the glass plate supporting structure can be formed only by forming the rail, which is convenient.

It is not limited to the order of right, bottom and left, and it is not necessary to be integrated or fixed by assembling, but it is configured such that the mounting hole and the hook are pressed against each other, and directly fixed integrally It may be done. Also, when rails are combined with each other, the lower rail must be combined with the right rail, and the left rail does not need to be combined with the lower rail. It is not necessary to make the hole engage with the projection or the concave portion and the piece with the pressing, and the mode can be variously changed, such as using the claw and the locking hole without the pressing.

Furthermore, the left rail and the closing member do not need to be mounted by a common fixing member. In addition, the attachment of each rail to the corresponding rail rib is not limited to a mode in which the hook is hooked on the mounting hole, and may be a mode in which the claw is locked in the hole. Furthermore, the various rails are not limited to the right and left and lower U-shape arrangement, but may be a U-shape opened to the left, include a semicircle, or have a glass plate inserted and closed on all sides. Can be.

The various lamp substrates may be fixed not only to the base but also to the lamp decoration side, or may be omitted together with the corresponding lamp decorations. Further, the front frame is not limited to the front frame that is pivotally connected to another portion of the pachinko machine by sliding engagement. Each rail does not need to be provided with the first to third pieces to hold two glass sheets, but to provide the second piece to support one glass sheet or to support three or more glass sheets. You can do it. The present invention can also be applied to other pachinko machines whose opening portion of the front frame is not circular, and to other gaming machines other than pachinko machines.
