The fixed plate /4 (fixes the game board l as a workpiece, and has position regulating protrusions /1 and /1 protruding upward on the top surface. Therefore, as shown in Fig. 3, When placing the game board L on the fixed board /41 that has been pulled out, insert the position regulating protrusions /I and /l into the position regulating holes.

! By fitting it inside, the game board l can be easily set in a predetermined position. The outer partition board and the inner picture board 3 are temporarily fixed to the game board l in advance.

As shown in Fig. 4, the outer partition plate is made by cutting a metal band plate to a predetermined length, and forming fixing holes 1 through which split pins 6 are passed.
9... are provided at predetermined intervals near the lower edge. The cotter pin 6 is made by folding a narrow plate material or wire material in half into a hairpin shape with both ends pointed, and the one shown in the drawing has a retaining protrusion 6' formed in the middle of its length. .

Therefore, after passing the split pin 6 through the hole lt as shown in FIG.
When inserted into the small holes by hand one after another, the outer drawing board bends due to its elasticity and can be temporarily fixed in a predetermined arc shape.

In addition, the inner drawing board 3 is also a metal band plate similar to the outer drawing board -, and has fixing holes/? By sequentially inserting the split pins 6 passed through the small holes in the game board l, they can be temporarily fixed in an arc shape.

As above, the game board/outer drawing board - and inner drawing board 3 are placed on the surface.
After temporary fixing, the fixed plate /4 is driven by the cylinder 12.
(When you move the end of the fixed plate, 27
It comes into contact with and stops at a predetermined position below the press plate/6. In this state, when the pressing plate 6 is lowered and pressed by the pressing tool J/... provided on the bottom surface of the pressing plate 1, each split pin 6 deeply enters the small hole, and both partition plates 1 and 3 are pressed. can be firmly fixed.

As shown in FIG. 6, the pressing tool a/ is provided with an elevating member U urged downward by a spring inside a cylindrical casing 3 having a fixing protrusion n at the upper end.
At the bottom end of the compartment board.

In addition to providing a partition plate abutting portion core having a notch portion which is slightly wider than the thickness of No. 3 and has an opening that widens toward the end,
Place the claw-shaped cotter pin clamping parts on both sides of the partition plate abutting part, and insert the claw-shaped split pin holding parts into the support shaft. , 29. Note that the split pin holding parts ko and -j are biased by a spring 30 so that the distance between their lower ends is always widened. The pressing tools configured as described above are fixed to the lower surface of the pressing plate in accordance with the positions of the split bottles 6 of the outer partition plate and the inner partition plate 3. Further, on the lower surface of the pressing plate 16, three auxiliary guide tools having a guide notch 3/ similar to the notch of the partition plate abutting part are installed at an angle of −7° to the pressing tool. / are arranged appropriately between.
