3 extends along the front frame 2 with a bulge forming a reinforcing cavity 29 between the front frame 2 and the front frame 2, as shown in FIG.
0, a first bent surface 25 that falls from the outer surface 24 into the front frame opening 3 along the side surface of the shelf 15 of the front frame 2, and from the lower end of the first bent surface 25. It is composed of a second bent surface 26 extending inwardly along the bottom surface of the shelf 15 of the front frame 2, and a third bent surface 27 rising from the tip of the second bent surface 26 in the extending direction. ing.

These outer surfaces 24, first bent surfaces 25, and second bent surfaces 26
, the third bent surface 27 is integrally formed by press working. Note that the first to third curved surfaces 25 to 27 are not formed over the entire length of the horizontal frame 22, 23, and some portions are provided with cutouts. The metal frame 4 is fixed to the front frame 2 by passing screws 31 through fixing holes 30 formed in the outer surface 24 and screwing them onto the front frame 2. In the illustrated embodiment, a fastening hole is also formed in the second bent surface 26, and the metal frame 4 is fixed to the front frame 2 by passing screws through the fastening hole.

Further, the first bent surface 25, the second bent surface 26, and the third bent surface 27 described above form a first prevention space 28 that prevents unauthorized members from entering between the metal frame 4 and the glass door frame 5. are doing. In addition, the outer surface 24 is bulged to form a reinforcing cavity 29 between it and the front frame 2, so that the rigidity of the metal frame 4 itself is increased and the metal frame 4 can be easily attached to the front frame 2. It has the effect of increasing the strength of.

By the way, the upper end of the left vertical frame 20 on the side where the glass door frame 5 and front plate 6 are pivotally supported among the frame frames 20 to 23 is bent so as to enter the first blocking space 28, and The support hole 32 is formed at a position extending from the first bent surface 25 of the upper horizontal frame 22. Further, an intermediate support plate 33 is provided at a position slightly below the middle of the left vertical frame 20 so as to enter the first blocking space 28, and a through hole 34 is bored in the center of the intermediate support plate 33. There is. Note that the intermediate support plate 33 is press-formed by itself, and is joined by spot welding from the back surface of the first bent surface 25 of the left vertical frame 20. Therefore, the back surface of the first bent surface 25, on which the intermediate support plate 33 is provided, is in a somewhat protruding state.

Further, at the end of the lower horizontal frame 23, the first bent surface 2
A support hole 35 is formed in 5.

The support hole 32, through hole 34, and support hole 35 described above are
It constitutes the other hinge element, and the glass door frame 5
It also engages with one of the hinge elements provided on the front panel 6, which will be described later, to ensure smooth opening and closing operations of the glass door frame 5 and the front panel 6.

On the other hand, the right vertical frame 21 is provided with a locking mechanism for locking the glass door frame 5 and the front plate 6. Of these, the locking device 40 that locks the glass door frame 5 includes a locking auxiliary plate 41 fixed along the third bent surface of the right vertical frame 21 and the locking auxiliary plate 4
1, and a locking plate 42 that is provided to be slidable up and down.

A locking part storage notch 43 is formed at two places on the top and bottom of the locking auxiliary plate 41 to accommodate a locking part (not shown) fixed to the side surface of the glass storage member 61 of the glass door frame 5. At least the lower edge of the stopper housing notch 43 forms a lower edge inclined portion 44 that is inclined in the opening direction. Further, a regulating vertical portion 4 extends vertically upward from the rear end of the lower edge inclined portion 44.
It is 5. The locking plate 42 is always biased upward by a spring 46 interposed between it and the auxiliary locking plate 41, but this is due to the guide bin protruding from the auxiliary locking plate 41. 47 is guided by passing through a guide hole 48 formed in the locking plate 42. The guide hole 48 is formed in the shape of an oblique oblong hole that moves closer to the front as it goes from top to bottom, and when the locking plate 42 is pushed down against the biasing force of the spring 46, it serves as a locking aid. The entire locking plate 42 comes to protrude forward with respect to the plate 41.

The locking plate 42 has a rearwardly extending operating lever 49 secured to it approximately in the center thereof, and locking claw portions 50 are formed above and below the operating lever 49 . The operating lever 49 is operated when you want to open the glass door frame 5 from the back of the pachinko game machine 1 while the front frame 2 is open. By pushing down the operating lever 49, the locking plate 42 is moved downward. Then, the glass door frame 5 can be opened. In the illustrated embodiment, the operating lever 49 can be rotated relative to the locking plate 42, so that the protruding state of the operating lever 49 may be an obstacle when carrying the metal frame 4 at a manufacturing factory. In such a case, the operating lever 49 can be rotated to prevent the operating lever 49 from protruding.

The locking claw portion 50 is provided at a position corresponding to the locking portion storage notch 43, and the receiver whose front edge is inclined in the direction of opening constitutes an inclined surface 51, and whose rear edge is substantially vertical. However, from the lower end of the rear end edge, a relief slope 52 is formed that slopes rearward, and from the upper end of the relief slope 52, it slopes forward. A pushing inclined surface 53 is formed.

To explain the operation of the locking device 40 configured as described above, first, when the glass door frame 5 is locked to the locking device 40, the locking portion (not shown) of the glass door frame 5 is locked. It is in a state of engagement with the rear end edge of the claw 50. When the locking plate 42 starts moving downward in this state, the locking plate 4
2 moves downward while moving forward slightly by engagement with the guide bin 47 and the guide hole 48. At this time, the engaging claw 5
Since the escape slope 52 located at the rear of the glass door frame 5 is inclined rearward, the locking portion of the glass door frame 5 can move smoothly. When the locking plate 42 further moves downward, the upper end of the locking portion of the glass door frame 5 moves forward while coming into contact with the pushing slope 53, and when pushed out, the locking claw 50 Because it is in a position that does not engage with the apex, the glass door frame 5
The locking portion becomes free and the glass door frame 5 can be opened. After the glass door frame 5 is opened, the locking plate 42 is moved upward by the biasing force of the spring 46.

Next, when the glass door frame 5 is to be closed, the locking plate 42 is in an upwardly moved state. Therefore, the lower end of the locking part of the glass door frame 5 comes into contact with the inclined surface 51, but since the inclined surface 51 of the receiver is inclined toward the rear, the receiver strongly presses the glass door frame 5. By doing so, the lower end of the locking part of the glass door frame 5 presses against the inclined surface 51 and the locking plate 4
Move backward while holding down 2. Then, when the locking plate 42 passes over the top of the locking pawl 50, the locking plate 42 rises again due to the biasing force of the spring 46, and the locking portion of the glass door frame 5 and the locking pawl 50 engage with each other, causing the glass door to open. The frame 5 is locked to the metal frame 4. Note that the lower edge inclined portion 44 of the locking portion storage notch 43 formed on the locking auxiliary plate 41 does not have any effect when the glass door frame 5 maintains an accurate position with respect to the metal frame 4. However, even if the locking part side shifts slightly downward when the glass door frame 5 is opened, the lower end of the locking part is guided upward when the glass door frame 5 is closed, and the locking part is smoothly moved to the correct locking position. It allows you to move.

Glass Door Frame Next, the structure of the glass door frame 5 will be explained with reference to FIGS. 1, 5, and 6.

The glass door frame 5 includes a front part 60 located so as to be continuous with the outer surface 24 of the metal frame 4, and a glass storage member provided on the back side of the front part 60 in the frame part excluding the upper part of the glass door frame 5. 61.

It is accommodated in the lower accommodation space. For this reason, the shelf on the support side is not formed larger than necessary, allowing quick and accurate positioning, and since the hinge elements do not come into contact with the front frame, the glass door frame and front Smooth opening and closing operations of the face plate can be ensured. Furthermore, the metal frame is provided with a reinforcing cavity, and the glass door frame is provided with a reinforcing bent portion, thereby increasing the strength of the metal frame and the glass door frame.

Further, the first curved surface, the second curved surface, and the third curved surface of the metal frame form a first prevention space for preventing unauthorized parts from entering, and further, the glass storage member of the glass door frame, the metal frame and the front surface are formed. Since the frame and the game board support member form a second prevention space for preventing unauthorized parts from entering, the game board can be inserted between the metal frame and the glass door frame or between the glass door frame and the glass. It is possible to prevent unauthorized parts from entering and reliably prevent fraud.
