The holding device of this embodiment for the game board 7 includes a holding frame 11 attached to the back side of the window frame 2 of the front frame 1.
A set of holding mechanisms are arranged on both sides of the holder. First, the holding frame 11 is fixed to a support rod 3 for a spacer attached to the back of the window frame 2, and a locking edge 1 for the back edge of the game board 7 is attached to the upper rod and left and right side rods.
2 and 13 are formed, and openings 14 and 14 are formed at the top and bottom of the left and right side rod portions.

The above-mentioned holding mechanisms are basically constructed in the same way even if there are slight differences between them.For convenience, one (the left side in the figure) will be explained.
A pair of upper and lower engaging and holding plates 15, 15 are fitted with pins 16 in alignment with the respective openings 14, 14 of 1. Both retaining plates 15, 15 can move in and out of the window frame 2 by using the corresponding opening 14 based on rotation, and can enter and exit the window frame 2 at the tip thereof into the corresponding engagement hole 10 of the frame 8. Engagement pieces 17, 17 are formed which can engage and disengage the engagement edge 9 with appropriate elastic force.
Note that each engagement piece 17 has a guide portion 17a formed in a curved shape for the engagement hole 10. As shown in FIG.

An operating rod 18 that can be operated from the back side of the front frame 1 using a knob 19 is connected by a pin 20 between the other ends of the upper and lower engagement holding plates 15, 15.
By raising and lowering the engaging and holding plates 15, 15, the two engaging and holding plates 15, 15 can be operated as described above. Reference numeral 21 denotes a locking rod with a pin 22 attached to the lower end of each side rod of the holding frame 11, and the operating rod 18 can be in an upright position using a spring 23 when operated from the back side of the front frame 1, or in an upright position. 18 can be switched to a sideways state in which it is released. 24 is holding frame 1
A pressing support piece made of a leaf spring is attached to the center of each side rod part of 1, and its tip can be inserted into the opening 25 formed in the locking edge 13 and can be pressed against and locked to the back surface of the game board 7.

The holding device of this example configured as described above can attach and 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 11 and set on the ball launching board 4, the back side of the peripheral edge is positioned and held by the back plate 6, each locking edge 12, 13, and the pressing support piece 24. Further, the front side of the lower edge is held aligned with the ball launcher 4 by the locking pieces 5, 5.

By upwardly operating the game board 7 based on the operating rods 18 in the holding mechanisms on each side, the upper and lower engaging holding plates 15 both rotate inward, and the engaging pieces 17 are opened. 14 to the engagement hole 10 on the game board 7 side
It plunges into the inside and presses into engagement with the engagement edge 9. As a result, the entire game board 7 is elastically pressed against the holding frame 11, and the front sides of both sides of the board are also positioned and held.
It is firmly held between the holding frame 11 and each engagement holding plate 15 in a state where it is sandwiched between the front and back. Then, by raising the locking rod 21 and locking the operating rod 18 in the upward movement position, the operating rod 18 is prevented from accidentally lowering due to shocks, vibrations, etc., and the engagement holding plates 15 on each side remain in the engaged state. Can be held stably.

On the other hand, by tilting the stopper rod 21 sideways and lowering the operating rod 18, the upper and lower engagement holding plates 15, 15
rotates outward to move the engaging piece 17 away from the engaging edge 9 and the engaging hole 10, releasing the pressing hold on the game board 7. Under this condition, the game board 7 inside the holding frame 11 can be easily taken out from the front surface of the window frame 2.

In particular, in this example device, by arranging the pressing support pieces 24, 24, even if each side edge of the game board 7 exhibits a different warpage, etc., the elasticity of the support pieces 24 can be used to prevent the board from playing. 7 can be properly pressed and held.

Note that part of the device of this example may be changed. For example, the locking rod 21 may be replaced with a locking tool that also serves as a stopper, and the operating rod 18 may be moved up and down by rotating the locking tool. Also, the engagement piece 17 of each of the upper and lower engagement holding plates 15 connected to the operating rod 18
may be configured to be able to engage and disengage from the opening 14 of the holding frame 11 to the engagement hole 10 formed at the side end of the game board 7, as shown in FIG.

As described above, according to the holding device of the present invention, the detachable and replaceable game board separated from the batting ball launching board is positioned and held by being inserted into the holding frame on the back from the front of the window frame of the front frame. By simply operating the operating members on both sides of the holding frame on the back side of the front frame, for example in the upward restraining direction, the engaging holding members on each side will plunge into the inside of the window frame and the engaging pieces will be moved to each side of the game board. The game board can be held so as to be pressed to the back side by being press-fitted to the engaging part of the part. Conversely, by simply operating the operating member, for example, in the downward release direction, the engaging and holding members on each side are moved out of the window frame, the engaging pieces are disengaged from the engaging portions, and the game board can be released. . 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, in the present device, the rear locking edge of the holding frame;
an engagement holding member actuated by the operating member;
Since it is possible to accurately press and hold both side edges of the game board, which has been considered difficult, it is possible to prevent warping of both side edges and maintain the entire game board in a proper posture, which in turn makes it possible to hold the game board in its proper position. It can be properly matched against.
Moreover, since the operating members on each side can be locked in the operating position using the locking member, it is possible to proactively prevent the operating members from falling accidentally due to vibrations or shocks when opening and closing the front frame, or loosening of the engagement holding member. This prevents the game board from wobbling or the like, thereby allowing the game board to be stably held at an accurate position for a long time.
