Locking edges 10a and 10b for the back edge of the game board 6 are formed at 0A and 10B.

The holding means includes each side rod 10A of the holding frame 10,
10A is basically configured in the same way.
To explain one side for convenience, a pair of upper and lower engagement holding plates 12, 12 are fitted with pins 13 in alignment with respective openings 11, 11 formed on the upper and lower sides of each side rod 10A. Both retaining plates 12, 12 can move in and out of the window frame 2 by using the corresponding opening 11 based on the rotation, and have their tips inserted into and out of the corresponding engagement hole 9 of the frame 7. Engagement pieces 14, 14 are formed which can engage and disengage the engagement edge 8 with appropriate elastic force. Note that each engagement piece 14 has a guide portion 14a for the engagement hole 9 formed in a curved shape.

An operating rod 15 that can be operated from the back side of the front frame 1 using a knob 16 is connected between the other ends of the upper and lower engagement holding plates 12 and 12 by a pin 17, and by raising and lowering the rod 15, both the holding plates can be held. Plates 12, 12 may operate as described above. Reference numeral 18 denotes a locking rod having a pin 19 attached to the lower end of each side rod 10A of the holding frame 10, which can be operated from the back side of the front frame 1 to lock the operating rod 15 in the raised position using a spring 20, and in an upright state. 15 can be switched to a sideways state in which it is released. 21 is each side rod 10
A pressing support piece made of a leaf spring is attached to the center of A, and its tip can be inserted into the opening 22 formed in the locking edge 10a and can be locked in pressure contact with the back surface of the game board 6.

In the pressing means, the upper rod 10B of the holding frame 10

It is held by a pressing plate 25 attached to 0B. Each receiver tube 23 has a downward conical shape and is formed to be shallower than the radius of the pressure contact piece 24, and its small opening is appropriately smaller than the diameter of the pressure contact piece 24. As a result, the upper and lower circumferential portions of the press-contacting piece 24 protrude from the receiving tube 23, respectively, and the lower circumferential portion can be pressed against the upper end surface of the frame 7 of the game board 6. The pressing plate 25 is made of a leaf spring and always urges the pressing piece 24 downward by an elastically deformable free end 25a. Reference numeral 26 denotes a back plate attached to the back surface of the ball launching board 4 and the lower ends of both side rods 10A, 10A of the holding frame 10, which can abut and hold the lower back surface of the game board 6.

The holding device of this example configured as described above can attach and hold the game board 6 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 6 is fitted into the holding frame 10 in the forward tilted state and set substantially vertically on the ball launching board 4, each of the locking edges 10a, 10a of the holding frame 10,
The rear side of the peripheral edge is positioned and held by the pressing support pieces 21 and the back plate 26, and the front side of the lower edge is aligned and held with the ball launching board 4 by the locking pieces 5, 5.
Note that the lateral distance between the board 6 and the frame 10 is extremely small.

By upwardly operating the operating rods 15 in the holding mechanisms on each side of the game board 6, the upper and lower engagement holding plates 12 rotate inward to release the engagement pieces 14.
enters into the engagement hole 9 on the side of the game board 6 through the opening 11 and is pressed into engagement with the engagement edge 8. As a result, the entire game board 6 is elastically pressed against the holding frame 10, both sides of its front side are also positioned and held, and is firmly held in a state where it is sandwiched between the holding frame 10 and each engagement holding plate 12 in the front and back. Ru. Then, by raising the locking rod 18 and locking the operating rod 15 in the upward movement position, the operating rod 15 is prevented from accidentally lowering due to shock or vibration, and each engagement holding plate 12 is stably held in the engaged state. can.

On the other hand, in the pressing means, each pressing piece 24 is pressed by the upper end surface of the game board 6 and moves upward against the pressing plate 25, and is pressed against the upper end surface in point contact by the elastic force of the pressing plate 25. Firmly press the board 6 downward. As a result, the game board 6 is fixed in close alignment with the ball launching board 4 without vertical wobbling, and is prevented from floating.

Then, the stop rod 18 is turned sideways and the operating rod 15 is
By lowering the upper and lower engagement holding plates 12,
12 rotates outward, the engagement piece 14 is disengaged from the engagement edge 8 and the engagement hole 9, and the game board 6 is released from being pressed. The game board 6 originally inside the holding frame 10 can be easily removed from the front surface of the window frame 2. Note that after the game board 6 is removed, each pressure contact piece 24 is pushed back to its original position by the pressure plate 25 in the above-described pressing means.

Note that part of the device of this example may be changed. For example, the locking rod 18 may be replaced with a locking tool that also serves as a stopper, and the operating rod 15 can be moved up and down by rotating the locking tool. In addition, each engagement holding plate 12
The engagement piece 14 can be engaged and detached from the opening 11 of the holding frame 10 into an engagement hole formed at the side end of the game board 6. This is the case. The pressing means is a holder 27 attached to the upper rod 10B with screws or the like as shown in FIG.
The pressure contact piece 24, which is prevented from coming out by the adjustment stopper 28, is slid into the inside, and the pressure contact piece 24 is projected downward from the hole 29 of the upper rod 10B, and is biased downward by the pressure spring 30, so that the lower end ball head The upper surface of the game board 6 may be pressed against the upper surface of the game board 6. In either format, board 6
If, for example, a V-shaped locking groove 31 is formed on the upper end surface of the frame 7 and the pressure contact piece 24 is locked in the same groove, the downward pressing of the board 6 and the prevention of forward movement of the upper part of the board can be prevented. obtain. Note that the pressure contact piece may be formed of a spring material.
The pressing means may be attached to one side of the holding frame 10, for example, the right side rod 10A.

As described above, according to the holding device of the present invention, with respect to a game board that is positioned by being inserted into the holding frame on the back side from the front side of the window frame of the front frame, the operating members on each side of the holding frame are moved, for example, in the upper restraining direction. Just operate to
The engaging and holding members on each side can be rotated so that their engaging pieces are pressed into engagement with the engaging parts on each side of the game board to hold the game board against the back side, and the operating member can be For example, simply by operating in the downward release direction, the engagement and holding members on each side rotate to separate the engagement pieces from the engagement portions, thereby releasing the play 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 edges of the holding frame and the engagement holding member 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 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.

In addition, since the pressing piece in the pressing means presses the game board downward with its biasing force, the top and bottom of the board is no longer rattled, and the board is properly aligned with the ball launching board, and in particular, the rails are prevented from being misaligned. Maintain proper communication at all times. The pressure contact pieces are spherical and can be moved up and down by utilizing the elastic deformation of the pressure piece by a spring, so when the game board is taken in and out, each pressure contact piece has a spherical shape at its lower end. The upper surface of the game board can be brought into pressure contact with the upper surface of the game board in a point-contact state and smoothly without any force, and can also be released.
