Incidentally, in each engagement holding plate 13, the operating lever 14 can be rotated 90 degrees using the notch 16 formed in the side rod 12A.

Each of the pivots 17 has a support pin 18 inserted into a hole 24 of the side rod 12A and a hole 25 of the engagement holding plate 13.
, a spring 19 fitted into the pin 18, and a cap nut 20.
By tightening the threaded shaft 21 at the tip of the support pin 18 via the washer 22 and engaging with the engagement step 23 at the tip of the support pin 18, the engagement is held by the elasticity caused by the compressive deformation of the spring 19. The plate 13 is always biased in the direction of close contact with the side rod 12A with a constant tightening force that allows rotation, and is supported without rattling or loosening. However, the engagement holding plate 13 is engaged with the game board 7 without slight displacement by utilizing the slight variable amount (compressive deformation amount) remaining in the spring 19.
The material is pressed with the most effective elastic force.

In the pressing means, the upper rod 12B of the holding frame 12
A spherical pressure welding piece 27 is fitted into the receiving cylinder 26 formed on both sides so as to be movable up and down, and this pressure welding piece 27 is attached to the upper rod 1.
It is held by a pressing plate 28 made of a leaf spring attached to 2B. Each receiving tube 26 has a downward conical shape and has a pressing piece 27.
The small diameter opening is appropriately smaller than the diameter of the pressure contact piece 27. As a result, the upper and lower circumferential portions of the press-contacting piece 27 protrude from the receiving tube 26, respectively, and the lower circumferential portion can be pressed against the upper end surface of the outer frame 8 of the game board 7. The press plate 28 always urges the pressure contact piece 27 downward by an elastically deformable free end 28a. Reference numeral 29 denotes a back plate attached to the back surface of the ball launching board 4 and the lower ends of both side rods 12A of the holding frame 12, which can abut and hold the lower back surface of the game board 7.

The holding device of this example can hold the game board 7 fitted from the front side of the window frame 2 of the front frame 1 by a simple operation from the back side. That is, when the game board 7 is fitted into the holding frame 12 and set on the ball launching board 4, the rear side of the peripheral edge is positioned and held by the locking edges 12a, 12b of the holding frame 12 and the back plate 29. The locking pieces 5, 5, the engaging piece 6, and the engaging opening 11 hold the ball in alignment with the ball launcher 4. Note that the lateral distance between the panel 7 and the outer frame 8 is extremely small.

For such a game board 7, each holding means rotates the operating part lever 14 to the hanging position.
Both the engagement holding plates 13 rotate inward and their engagement pieces 15 engage with the engagement edge 9 of the play board 7, and also protrude into the engagement hole 10 to release the spring 19 of the pivot member 17.
The pressing force is used to press against the front side edge of the board 7 and press it to the back side. As a result, the front side of both side edges of the game board 7 are also positioned, and the game board 7 is firmly held in a state where it is sandwiched between the front and back without any rattling from side to side. When holding the game board, even if the side edge of the board is slightly lifted from the corresponding side rod 12A, each engagement holding plate 13 will not hold its guide portion 15.
a can be engaged with the same side edge and pressed against the back side, thereby achieving appropriate press-fit engagement.

On the other hand, in the pressing means, each pressing piece 27 is pressed by the upper end surface of the game board 7, moves upward against the pressing plate 28, and firmly presses downward while remaining in pressure contact with the upper end surface. As a result, the game board 7 is fixed in close alignment with the ball launching board 4 without vertical wobbling, and is prevented from floating.

Then, by rotating each of the operating levers 14 to the horizontal position, the engagement holding plate 13 is rotated outward, and the engagement piece 15 is detached from the engagement edge 9 and the engagement hole 10. Release the pressure on the game board 7. Therefore, the game board 7 can be easily removed from the front surface of the window frame 2. Note that after the game board 7 is removed, each pressing piece 27 is pushed back to its original position by the pressing plate 28 in the pressing means described above.

Regarding the pivots 17 of each engagement holding plate 13,
The cap nut 20 may be a wing nut or a double nut, and the tool 17 itself may have a support tube 30 having a square tube portion 30a as shown in FIG. The shaft 21 is inserted into a predetermined position (the support tube 30 is attached to the side rod 12 through the screw hole 31).
Tighten the engagement retaining plate 13 to the position where it abuts A.
may be supported with a certain tightening force. On the other hand, in the pressing means, as shown in FIG.
The pressure contact piece 27, which is secured by the bolt 3, may be slid in, and the pressure contact piece 27 may be projected downward from the hole of the upper rod 12B and biased downward by the spring 35. In either type, if a V-shaped locking groove 36 is formed in the upper end surface of the frame 8 of the board 7, and the pressure contact piece 27 is locked in the same groove, the board 7 can be pressed downward and the upper part can be pushed forward. It is possible to prevent fluctuations in The pressure contact piece may be formed of a spring material. As shown in FIG. 12, the holding frame 12 is provided with a pressing support piece 37 made of a leaf spring on each side rod 12A as an auxiliary holding means, and the tip end 37a of the support piece 37 is
It is also possible to make it face into the opening 38 formed in the locking edge 12a of the side rod 12A and to be able to come into pressure contact with the back surface of the board 7.

As described above, according to the holding device of the present invention, the engaging holding plates on each side of the holding frame are connected to the operating part for the game board that is positioned by fitting from the front side of the window frame of the front frame into the holding frame on the back side. By simply rotating the retaining plate through the side edges of the game board, the holding plate can press into engagement with the engaging parts on each side edge of the game board and hold the board against the back side, and vice versa. You can leave and release the same board. Therefore, even an unskilled person can quickly and easily attach and detach the game board, replace it, inspect it, and maintain it through the simple operations described above, thereby simplifying the assembly work of the pachinko machine. In particular, with this device, the locking edge of the holding frame and the engagement holding plate properly clamp and hold both side edges of the game board, so warping of both side edges is suppressed and the entire game board is properly held. Can be held in position. Moreover, since the pressure contact piece in the pressing means presses the game board downward with a biasing force, the play board is prevented from wobbling and is more properly aligned with the ball launching board, and in particular, the rails are prevented from being misaligned. Maintains proper communication at all times.

Moreover, in this device, the engagement holding plate and the operating part are connected as a holding means, so it is easy to process (manufacture) and can be handled as a single item, and the structure is simple and can be easily assembled to the holding frame. obtain. Since the pivot of the engagement and retention plate is not simply a pin or shaft, but is assembled with a spring, the elastic force of the spring is used to prevent the engagement and retention plate from rattling or loosening. Therefore, the game board can be stably and rotatably supported, and the game board can be properly fixed and held for a long period of time.
