Are integrally formed on the outside of the second piece 31 so as to protrude outward in a state of being arranged so as to correspond to the mounting holes 21, 21,.
[0016]
On the other hand, the lower rail 27 is also formed in the same manner as the left and right rails 28 and 29 except that the front side when viewed from the back of the peripheral portion of the central collar portion 33 is a separate reinforcing portion 34. (FIG. 6 etc.). The reinforcing portion 34 is made of a material excellent in fatigue resistance and wear resistance, for example, acetal resin, and is fitted into a long concave portion formed in a part of the third piece 32 and a lower part of the second piece 31 from below. It has a shape including a rounded flange piece 36, a protruding portion 35 that closes the hole of the second piece 31 required for protruding molding of the flange portion 33, and a half portion of the central flange portion 33.
[0017]
Further, a receiving hole 40 is formed at the lower end of the right rail 29. Further, a pressing protrusion 41 having the same size as that of the receiving hole 40 protrudes from the right end of the lower rail 27, and a receiving piece 42 having a slightly smaller width than the lower rail 27 protrudes from the left end. In addition, the lower end of the left rail 28 is formed as a pressing portion 43 by forming a concave portion having substantially the same size as the receiving piece 42.
[0018]
And the right rail 29 is latched by pulling down in the state which put each collar part 33 in the upper part of the corresponding attachment hole 21 (FIG. 3). In the state pulled down, the flange 33 is located in a narrow portion in the front-rear direction of the attachment hole 21 and is in contact with the lower end. Further, the lower end of the right rail 29 is in contact with the lower rail rib 17. Similarly, the lower rail 27 is attached by being pulled to the right (FIG. 4). When the lower rail 27 is pulled to the right, the pressing protrusion 41 at the right end is inserted into the receiving hole 40 of the right rail 19 and is combined with the lower portion of the lower rail 27, and the receiving piece 42 located at the escape portion 24 is It moves to a position just to the right from the escape portion 24. Similarly, the left rail 28 is attached by being pulled downward. The pressing portion 43 at the lower end of the left rail 28 is in contact with the outer periphery of the receiving piece 42 of the lower rail 27 and the end face on which the receiving piece 42 stands.
[0019]
In addition, a closing member 45 having a U-shaped cross section is engaged between the left peripheral standing portion of the base 12 and the left rail rib 18 when the front frame 7 is locked to the main body frame 3 in a closed state. A part is inserted into the upper and lower through-holes 23 and 25 and attached so as to surround the closing member rib 46. At this time, the left side as viewed from the back of the closing member rib 46 and the small ribs 52 are in pressure contact with the closing member 45. Further, the flange piece 44 (FIG. 5) projecting on the right side when viewed from the back of the closing member 45 engages with the flange portion 47.
[0020]
And the reverse claw-shaped fixing member 50 having the locking claw 48 on the inner side and the entry piece 49 on the right side straddles the closing member 45 and locks the upper end thereof with the locking claw 48, The entry piece 49 is engaged with the upper side of the lateral rib 22 in a state where it enters the entire upper side where the uppermost mounting hole 21 is vacant and is slightly pressed against the uppermost flange portion 33 of the left rail 28 (FIG. 7, FIG. 7). FIG. 8). Due to the engagement of the fixing member 50 and the combination of the rails 27 to 29, the rails 27 to 29 are integrated with the front frame 7, that is, after attachment, even when the glass plate is taken in and out, It is fixed so as not to move relative to the frame 7. 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 rail 27 to 29 (all The glass plate 26 is inserted from above.
[0021]
In such a pachinko machine 1, the corresponding rails 27 to 29 are attached to the rail ribs 17 to 19 on the back surface of the front frame 7 that can be freely opened and closed on the side edges by hanging the flanges 33. Therefore, the support structure of the glass plates 26 and 26 can be formed or removed with one touch. Further, even if the rails 27 to 29, the base 12 and the like are formed of synthetic resin, the glass plates 26 and 26 can be sufficiently supported, and the entire front frame 7 can be configured to be lightweight. Thus, the front frame 7 can be easily handled during manufacturing or maintenance.
[0022]
Furthermore, when the end portions of the plurality of rails and the end portions of the adjacent rails are combined and attached in the order of the right rail 29, the lower rail 27, and the left rail 28, the fixing member 50 is attached only to the vicinity of the upper end of the left rail 28. All the rails 27 to 29 are fixed simply by engaging them, so that the fixing work for completing the mounting becomes easy, and the rails 27 to 29 are integrated with the front frame 7 after mounting and are simple. It is advantageous in terms of strength while having a simple structure. Here, since the closing member 45 which is a part of the locking mechanism is also attached by the fixing member 50 at the same time, the handling of the front frame 7 is further simplified.
[0023]
In addition, since the lower rail 27 is provided with a reinforcing portion 34 that is excellent in fatigue resistance and wear resistance, even if a game ball collides, it is possible to prevent cracking and chipping. Here, during the game on the pachinko machine 1, the game ball that has not won the prize device reaches the lowermost part of the circular game area (located substantially in the center in the left-right direction) and is viewed from the front for recovery. It is guided to the back and falls immediately in the back as seen from the front of the lower part of the front frame 7, while the winning game balls fall in the back as seen from the front. Among the lower rails 27 to 29, there is a possibility of colliding with the game ball in the central portion on the near side as viewed from the back, and therefore the reinforcing portion 34 occupies a necessary and sufficient position and range. . Further, since the reinforcing portion 34 closes the hole provided when the central flange portion 33 is formed, the strength can be improved and a gap for allowing the tool to enter can be eliminated to prevent an illegal act.
[0024]
In addition, since each rail rib 17-19 is integrally molded by the U shape surrounding three sides in the edge, it can resist warp or a torsion etc. in the whole front frame 7, and makes the front frame 7 high intensity | strength. In addition, since it is not necessary to stretch a rib, the front frame 7 can be easily formed, and the mounting strength of the rails 27 to 29 can be improved. Further, since the closing member 45 is fixed by the press-contact of the closing member rib 46 and the engagement of the flange piece 44 with the flange portion 47, the closing member 45 can be sufficiently fixed to the front frame 7. It is possible to prevent a situation where the front frame 7 is opened despite being locked.
[0025]
[Second Embodiment]

Hereinafter, parts similar to those in the first embodiment are denoted by the same reference numerals, and differences will be mainly described.
[0026]
The front frame 57 of the second embodiment is such that all the rails of the first embodiment are integrally formed with each rail rib, that is, the lower and left sides surround the three sides other than the upper side of the base 58. , Right rails 60, 61, 62 are erected integrally with the base 58. Each rail 60 to 62 includes a first piece 63, a second piece 64, and a third piece 65. The fixing member 50 fixes only the closing member 45.
[0027]
In the pachinko machine of the second embodiment, since the rails 60 to 62 including the first piece 63, the second piece 64, and the third piece 65 are integrally formed on the base 58 of the front frame 57, The strength can be sufficient, and if it is molded, a glass plate support structure can be formed, which is convenient.
[0028]

Still further, the mounting of the rail is not limited to the order of right, bottom and left, and it is not necessary to be integrated or fixed by the combination, so that the mounting hole and the collar portion are in pressure contact with each other. It may be configured and fixed directly and integrally. When the rails are combined with each other, the lower rail does not need to be combined with the right rail, and the left rail does not have to be combined with the lower rail. The mode does not need to be engaged with a hole and a projection or a recess and a piece with pressing, and can be variously changed such as a claw and a locking hole without pressing.
[0029]
Furthermore, the left rail and the closing member need not be attached 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 collar portion is hooked on the mounting hole, and a mode in which the claw portion is locked in the hole can be employed. Furthermore, the various rails are not limited to the left and right and bottom U-shaped arrangements, but are to be left U-shaped, include a semicircle, or close the four sides after inserting a glass plate. Can do.
[0030]
Further, the various lamp substrates can be not only fixed to the base but also assembled on the lamp decoration side, or can be omitted together with the corresponding lamp decoration. Further, the front frame is not limited to the one that is pivotally attached, such as slidingly engaging with other parts of the pachinko machine. In addition, each rail does not have to hold two glass plates by providing the first to third pieces, but supports up to the second piece and supports one glass plate or supports three or more glass plates. Can be. The present invention can also be applied to other pachinko machines whose front frame opening is not circular, and to other gaming machines other than pachinko machines.
