When the decorative board 21 is stored and held in the housing frame 10, the rear end face of the housing frame 10 and the back surface of the decorative board 21 are aligned and flattened.
[0024]
Now, in the housing frame 10 configured as described above, the locking mechanisms 50 are disposed at two positions on the left and right of the lower frame portion 12. FIG. 4 is a side sectional view of the vicinity of the locking mechanism 50 as viewed in the direction of arrow IV in FIG. 3, and FIG. 5 is a perspective view of the mechanism 50 as viewed from the back side of the housing frame 10. The locking mechanism 50 will be described with reference to FIG.
[0025]
The locking mechanism 50 mainly includes a locking metal member 51 that is attached so as to sandwich the lower frame portion 12 and protrudes upward. The locking fitting 51 has a base portion 51a supported on the upper surface of the lower frame portion 12, a front side of the base portion 51a is bent upward and a locking side portion 51b protruding upward, and a rear side of the base portion 51a is bent downward.

It is formed of a fixed side portion 51e and the like, in which a mounting hole is formed, which is bent downward to extend downward and through which a screw 58 is inserted.
[0026]
The distance between the rear surface of the locking side portion 51b and the rear end surface of the rear side portion 51c, that is, the front-rear dimension of the upper surface of the base portion 51a is set to be equal to or slightly smaller than the thickness of the decorative plate 21. . In addition, the upper end of the locking side 51b is gently bent toward the front to smoothly receive and guide the lower end of the decorative board 21 and prevent scratches on the decorative board surface. The locking metal member 51 is formed by molding a metal material such as a stainless steel plate or a cold-rolled steel plate having a thickness of about 1 to 2 mm into a shape shown in the drawing by using known processing means such as punching, bending, and press forming. To form a desired surface treatment.
[0027]
On the other hand, a receiving notch 12c is formed at a mounting position of the locking metal member 51 by cutting a rear edge portion of the lower frame portion 12 by a thickness of the locking metal member 51, and the receiving metal member 51 is mounted. The rear notch 12c receives the rear side 51c of the locking metal fitting 51 in the receiving notch 12c, and the rear end of the rear side 51c is flush with the rear end of the housing frame 10 including the left and right lower frames 12. It is to be arranged in. A cylindrical boss 12b that supports the front surface of the fixed side portion 51e is formed below the receiving notch 12c, and a screw receiving portion that receives the screw 58 is formed at the center thereof.
[0028]
At the left and right ends of the lower frame 12, corner frame-shaped backing plates 12 a, 12 a are formed to connect the lower frame 12 to the left and right frames 13, 14. At the left and right corners of the side, a backing plate receiving portion 42a which is counterbored by the thickness of the backing plate portion 12a according to the shape of the backing plate portion 12a is formed. The lower edge of the decorative board 21 is cut at an angle on the back side to form a flank 42e.
[0029]
The latch 51 has a base 51a placed on the upper surface of the lower frame 12 in accordance with the position of the receiving notch 12c. The lower frame 12 is fitted to and connected to the lower frame 12 so that the lower frame 12 is sandwiched between the lower frame 12 and the fixed frame 51d.
[0030]
When the locking fitting 51 is attached in this manner, the base portion 51a is supported on the upper surface of the lower frame portion 12, and the locking side portion 51b is disposed so as to protrude upward at the front side of the lower frame portion 12. The rear end surface of the rear side portion 51b is disposed on the same plane as the rear end surface of the housing frame 10, and the locking side portion 51b has a front-rear dimension between the rear surface and the rear end surface of the housing frame 10 of the decorative board 21. It is arranged in the front-rear direction position having the same size or slightly smaller than the plate thickness.
[0031]
When the game board 20 is mounted on the locking mechanism 50 configured as described above, the left and right side edges of the decorative board 21 are viewed from the front side of the game board 20 with the glass door 5 and the upper bowl 6 open. The game board 20 is held in a slightly forwardly inclined posture by gripping the portion, and the lower end of the decorative board 21 is inserted obliquely into the housing frame 10 from above the locking side 51b.
[0032]
Here, as shown in FIGS. 3 and 4, the height of the backing plate portion 12a is formed larger than the protruding height of the locking side portion 51b. For this reason, when the lower end portion of the decorative board 21 is inserted obliquely into the housing frame, the left and right backing plate receiving portions 42a are respectively engaged with the front surfaces of the backing plate portions 12a and guided, and the decorative board 21 is directly moved downward. , The left and right locking side portions 51b can be engaged with appropriate positions on the front surface of the decorative board. Since the upper end of the locking side 51b is gently bent toward the front, the decorative board 21 slid downward is smoothly guided at its lower end to the base 51a. The side portion 51b and the base portion 51a elastically deform to receive the decorative board 21 in an inclined posture. Thereby, the game board 20 is elastically biased and supported on the base portion 51a in the forwardly inclined posture.
[0033]
Further, since the flank 42e is formed at the lower end of the rear surface of the decorative board 21, the lower end of the decorative board 21 can be inserted into or removed from the game board 20 in an inclined posture or swung up and down. Even if the user attaches or detaches the back set board 30 without protruding backward from the rear end face and holding the back set board 30 closed so as to be in close contact with the rear end face of the storage frame 10, excessive stress may be applied to the back set board 30. Does not occur.
[0034]
Further, the rear end side of the locking metal member 51 is bent in a U-shape to form a holding side portion 51d, and is configured to hold the lower frame portion 12. Therefore, even if a force that tilts the locking side portion 51b forward acts and the locking side portion 51b and the base portion 51a are elastically deformed, the clamping side portion 51d transmits this force to the lower frame portion 12. And does not directly act on the fixed side portion 51e. Therefore, no excessive bending moment or tensile force acts on the boss 12b via the screw 58, and the boss 12b is not broken or the screw receiving portion is not damaged. In addition, by bending the locking fitting in this manner, the length of the elastically deformable region can be increased, and the locking mechanism that is flexible and hardly plastically deformed can be configured in a small size.
[0035]
In the embodiment, the locking side portion 51b of the locking metal is bent at a right angle to the base portion 51a, and the front-rear dimension between the rear surface of the locking side portion 51b and the rear end surface of the housing frame 10 is equal to that of the decorative plate 21. Although the form in which it projects vertically upward with substantially the same interval as the plate thickness is illustrated, the locking mechanism 50 is not limited to such a form and can lock the lower end portion of the decorative plate 21. Should be fine. For example, in the case where the same metal fitting as that of the embodiment is provided, a gap slightly larger than the thickness of the decorative board 21 is provided between the lower part of the locking side and the rear end face of the housing frame. The locking side portion 51b is positioned at a right angle to the base portion 51a with an interval slightly smaller than the thickness of the decorative board 21 between the upper side of the locking side portion and the rear end surface of the housing frame. May be bent at a small angle and projected in a slightly backward tilted posture. In the locking mechanism of such a form, even if there is a slight variation in the thickness of the decorative plate 21, the locking metal is elastically absorbed, and a gap is formed between the decorative metal and the decorative metal plate 21 or the locking metal is excessively large. No stress is generated.

[0046]
When the fixing member 63 and the temporary fixing member 65 are assembled in this manner, the operation member 61 is rotated from the front side of the front frame 2 to move the fixing member 63 downward from the upper frame portion 11 (inward of the housing frame 10). 8 (a)), and an open position (FIG. 8 (a)) where the decorative board 21 is stored in the upper frame 11 and released from engagement with the decorative board 21. 8 (b)). Further, when the fixing bracket 63 is located at the open position, the temporary fixing member 65 is disposed at a temporary fixing position protruding inward of the accommodation frame 10, and the game board 20 is detachably accommodated in the accommodation frame 10. The game board 20 is engaged with the housed game board 20 to temporarily support the game board in the housed posture.
[0047]
On the other hand, an upper edge engaging portion 41 is formed at the center of the upper edge of the decorative plate 21. The upper edge engaging portion 41 includes a backing plate receiving portion 41a formed on the back surface side of the decorative plate 21, an upper side portion 41b serving as an upper end surface of the decorative plate 21, and a temporary fixing fitting receiving groove formed on the front side of the decorative plate 21. 41c, an introduction surface 41e in which the upper end corner where the backing plate receiving portion 41a and the upper side portion 41b intersect is cut obliquely and formed in a slope shape, and a slope between the upper side portion 41b and the temporary fastener receiving groove 41c. It is composed of the formed locking surface 41f and the like.
[0048]
Among them, the backing plate receiving portion 41a is configured such that the rear surface side of the decorative plate 21 is a backing plate in accordance with the formation position and shape of the backing plate portion 11a formed so as to protrude from the upper frame portion 11 toward the inside of the housing frame 10. When the game board 20 is accommodated in the housing frame 10, the backing plate portion 11a is received by the backing plate receiving portion 41a, and the rear end face of the housing frame 10 and the decorative board are formed. The rear surface 21 is aligned with the front and rear to form a flat rear surface.
[0049]
Here, when the lower end portion of the decorative board 21 is engaged with the locking mechanism 50 and the game board 20 is swung in the closing direction, the introduction surface 41e is an introduction side portion of the temporary fixing metal at the temporary fixing position. The introduction side 65e is formed so as to be in contact with the introduction surface 65e and to be able to ride on the introduction surface 41e. The locking surface 41f is formed in alignment with the position of the locking side 65f of the temporary fixing member 65, and engages with the locking side 65f when the game board 20 is housed in the housing frame 10. The game board 20 is formed so as to be temporarily fixed in the accommodation posture.
[0050]
Now, the operation of the temporary support fixing mechanism 60 configured as described above will be described from the case where the game board 20 is mounted on the housing frame 10 first.
[0051]
The operator opens the glass door 5, rotates the operation bolt 61 from the front side of the front frame 2 using a hexagon wrench or the like, swings the fixing bracket 63 upward, and stores the fixing bracket 63 in the upper frame portion 11. Position. At this time, the temporary fixing member 65 is disposed downward, and the distal end side of the arm portion is disposed at a temporary fixing position where the front end side protrudes inward of the housing frame 10 from the opening 11d of the upper frame portion 11 (see FIG. 9). . The left and right fixing mechanisms 80 are also operated to rotate the operation bolts 82 so that the fixing brackets 81 are pivotally retracted downward (or upward).
[0052]
Then, the lower end of the decorative board 21 is obliquely inserted into the housing frame 10 using the above-described locking mechanism 50 to engage with the locking metal fitting 51, and the game board 20 is tilted forward on the base portion 51a. To be elastically supported. In this state, when the operator weakens the force in the forward tilt direction, the upper portion of the game board 20 is swung rearward by the elastic force of the locking metal fitting 51, and as shown by a solid line in FIG. The introduction surface 41e of the engaging portion 41 is supported in a temporary support posture in which the introduction surface 41e is in contact with the introduction side portion 65e of the temporary fixing member 65.
[0053]
When the worker presses the upper part of the game board 20 backward from the temporary support posture, the arm part 65a is pushed by the introduction surface 41e moving rearward and swings rearward to allow the decorative board 21 to enter. , The introduction side portion 65e moves upward so as to slide on the slope of the introduction surface 41e. When the decorative plate 21 is further tilted and the lower end corner of the introduction side portion 65e moves to the upper end of the introduction surface 41e and the engagement is released, the arm portion 65a, which has been elastically deformed rearward, moves forward by elastic force. Then, the locking side 65f is displaced so as to slide down the locking surface 41f, and the locking side 65f and the locking surface 41f are engaged. Also, at this time, the backing plate receiving portion 41a of the decorative board comes into contact with the backing plate portion 11a, and the game board 20 is temporarily fixed to the housing frame 10 in the housing posture.
[0054]
In this temporarily fixed state, the locking side 65f of the temporary fixing member 65 is engaged with the locking surface 41f of the decorative plate 21 to hold the decorative plate 21 between the decorative plate 21 and the backing plate 11a. Even if the operator releases the pressing force of pressing the decorative board 21 backward, the game board 20 is maintained in the housed posture (the temporary fixing metal fittings indicated by the two-dot chain lines in FIG. 8B and FIG. 6). 65). For this reason, the game board 20 does not fall out of the housing frame 10 or slide out.
[0055]
After the game board 20 is temporarily fixed in this manner, the operator rotates the operation bolt 61 clockwise from the front of the front frame 2. When the operation bolt 61 is rotated, the tip of the temporary fixing member 65 moves upward along an arc trajectory, and accordingly, the tip of the fixing member 63 moves downward along an arc trajectory. The curved surface area of the pressing portion 63c gently bent and formed forward on the distal end side of the lever portion 63 smoothly engages with the front surface of the decorative board 21. When the operation bolt 61 is further rotated, the engagement between the locking side portion 65f of the temporary fastener and the locking surface 41f of the decorative plate is released, while the curved surface region on the tip side of the pressing portion 63c moves downward. As a result, the flat area on the base end side of the pressing portion 63c engages with the front surface of the decorative board 21 to press the decorative board 21 backward.
[0056]
Then, when the lever portion 63a of the fixing member is swung to a fixing position extending vertically downward, the temporary fixing member 65 is stored horizontally in the upper frame portion 11, and the pressing portion 63c of the fixing member moves the decorative plate 21 rearward. The game board 20 is fixedly held on the housing frame 10 so that the decorative board 21 is sandwiched between the game board 20 and the backing plate portion 41a (see FIGS. 8A and 6).
[0057]
In a state where the game board 20 is fixed and held in the housing frame 10 in this manner, the backing plate portion 11a is received by the backing plate receiving portion 41a, and the rear end surface of the housing frame 10 and the back surface of the decorative board 21 are aligned in front and rear. A flat back surface is formed. For this reason, a flat surface is formed on the back surface side of the housing frame 10, and a configuration in which compatibility with the back set board 30 closed behind is improved. The backing plate portion 11a is formed so as to protrude from the inner surface of the upper frame portion 11 toward the inside of the housing frame 10, and the backing side of the decorative plate 21 is counterbored to form the backing plate receiving portion 41a. Therefore, the thickness of the front frame 2 including the housing frame 10 can be made thin.
[0058]
On the other hand, when removing the game board 20 fixed and held by the housing frame 10, the glass door 5 is opened, and the operation bolt 61 is rotated counterclockwise from the front of the front frame 2 using a hexagon wrench or the like. .
[0059]
When the operation bolt 61 is rotated counterclockwise, the pressing portion 63c of the fixing bracket 63 moves upward along an arc trajectory, and the leading end of the temporary fixing bracket 65 moves downward along the arc trajectory. First, the rear corner of the locking side 65f of the temporary fastener engages with the locking surface 41f of the decorative board. When the operation bolt 61 is further rotated, the locking side portion 65f of the temporary fixing metal and the locking surface 41f of the decorative plate are engaged in surface contact, while the pressing portion 63c moves upward to make contact with the fixing metal member 63. The engagement with the decorative board 21 is released.
[0060]
When the fixing bracket 63 is swung to an open position where the fixing bracket 63 is horizontally stored in the upper frame portion 11, the lever portion 65a of the temporary fixing member is disposed at a temporary fixing position extending vertically downward. The perimeter 65f engages with the locking surface 41f of the decorative board to temporarily fix and support the game board 20 to the housing frame 10 (see FIG. 8B). For this reason, even if the operator does not press the game board 20 during the opening operation, the game board 20 does not fall out or slide out of the housing frame 10 and the fixing bracket 63 is moved to the open position. The gaming board 20 is also held in the temporarily fixed posture temporarily fixed to the housing frame 10 when the game board 20 is positioned.
[0061]
Next, from this temporary fixing posture, the decorative board 21 is pulled forward by placing a finger on a game nail or an outer rail above the game board, for example. At this time, since the lower end of the front surface of the decorative board 21 is locked by the locking metal member 51, the game board 20 tends to tilt forward around the locking portion. For this reason, the locking side portion 65f engaged with the locking surface 41f is pulled forward, and the arm portion 65a is elastically rocked and deformed, allowing the game board to tilt in the forward tilt direction, The retaining side 65f moves upward so as to slide on the locking surface 41f.
[0062]
When the lower end corner of the locking side 65f moves to the upper end of the locking surface 41f and the engagement is released, the arm 65a elastically deformed forward self-returns to the rear by elastic force, It returns to the state before the temporary fixing shown in FIG. In this state, the lower end of the decorative board 21 is in a temporary supporting position elastically supported by the locking metal fittings 51, and the game board does not fall forward even if the front side of the game board 20 is not supported. Therefore, the operator can remove the game board 20 by holding the appropriate position with both hands to carry out the game board 20 and pulling out the decorative board 21 obliquely upward.
[0063]
As described above, in the pachinko machine PM of this configuration, when the game board 20 is locked by the locking mechanism 50, the game board 20 is locked in the temporary support posture urged in the housing direction, and When the housing 20 is housed in the housing frame 10, it is temporarily held in the housing posture by the temporary support and fixing mechanism 60, and the game board is maintained in the housing posture even when the fixing by the fixing bracket 63 is released. For this reason, at the time of attaching / detaching the game board, even if the game board 20 housed in the housing frame 10 is not supported, the game board 20 does not fall down or slide out, so that the game board is dropped. Alternatively, the risk of damaging the connector cable connected to the back side of the game board can be prevented beforehand, so that even an unskilled person can easily and safely mount and remove the game board.
[0064]
In the above description, the introduction surface 41e and the locking surface 41f are formed on the upper edge portion of the decorative plate 21, and the leading end portion of the temporary fixing member 65 is bent and formed in multiple stages to introduce the introduction side portion 65e and the locking side portion 65f. In the illustrated embodiment, the engaging side 65f is relatively displaced so as to get over the upper side 41b and engages with the engaging surface 41f to temporarily support the game board 20. The portion may not be provided with the introduction surface 41e, the locking surface 41f, the temporary fixing metal receiving groove 41c, and the like as described above. That is, only the backing plate receiving portion 41a and the upper side portion 41b are provided on the upper edge engaging portion 41 of the decorative plate 21 to form the upper edge flat, and as shown by the two-dot chain line in FIG. A temporary fixing member 65 'having a curved engaging portion is engaged and supported by the operation bolt 61 in the same manner as described above, and the engaging portion and the upper side are frictionally engaged by utilizing the elastic force of the temporary fixing member 65'.
