が生じてしまう欠点があつた。 When controlling the flow of steel balls such as pachinko balls flowing in a gutter, an opening/closing plate that moves up and down toward the bottom of the gutter is used, but this type of opening/closing plate has a fixed width in the horizontal direction. It is difficult to maintain a completely horizontal state over the entire length. For this reason,
As shown in Fig. 1, when the lower end of the dam plate 3' comes into contact with one of the balls 2a' and is prevented from descending any further, the balls 2b', 2c' are placed on either the left or right side of the abutting part. There was a problem that the closing function did not work satisfactorily because there was a gap in which ... could pass freely. In addition, as shown in Figure 2, it is known that the lower edge of the opening/closing plate is formed into a serrated shape to facilitate cutting into the flow of steel balls, but in the conventional type, the spacing between the ridges of the serrations is larger than that of the steel balls. Since the steel ball 2a' is sandwiched between the peaks of the opening and closing plate as shown in Figure 2, the opening and closing plate tilts only slightly, allowing the balls 2b' and 2c' to pass through the other gaps. The problem was that there was a sufficient amount of time between the two.

本考案はこのような欠点を解消するためになさ

供することにある。 The present invention was devised to eliminate these drawbacks, and its purpose is to provide an opening/closing plate that can reliably open and close the flow of multiple rows of balls from above and below.

以下、本考案の一実施例を第３図に基づいて説
明する。第３図において１は鋼球２ａ，２ｂ，２

板である。 An embodiment of the present invention will be described below with reference to FIG. In Fig. 3, 1 indicates steel balls 2a, 2b, 2
A gutter 3 through which c... passes in plural rows is an opening/closing plate that is installed vertically movably across the transverse direction in the gutter 1, and opens and closes the flow of the steel balls as a checkpoint by vertical movement.

本考案の開閉板３は樋１の底面に向けられた下
部端縁４を鋸歯状に形成するとともに、該鋸歯の

り、樋１の側壁と開閉板３の下端角の間に鋼球が
はさまれないように構成する。 The opening/closing plate 3 of the present invention has a lower edge 4 facing the bottom surface of the gutter 1 formed into a sawtooth shape, and the interval d of each sawtooth is smaller than the diameter of the steel balls 2a, 2b, 2c... It is formed to be larger than the radius of the sphere. The distance d' between the side wall 1' of the gutter 1 and the side edge of the opening/closing plate 3 is made narrower than the radius of the steel ball. Configure the ball so that it does not get caught.

本考案は以上の構成になるため、第３図のよう

１の球列に円滑に割り込ませるのに便利である。 Since the present invention has the above configuration, even if the serrations of the opening/closing plate 3 come into contact with the steel ball 2a and prevent the entire dam plate from descending as shown in Fig. 3, the interval d of the serrations is the diameter of the ball. Since the opening/closing plate is smaller, even if the opening/closing plate is slightly inclined, the other steel balls 2b, 2c, . Therefore, even if the flow pressure of the rear ball is high, a reliable damming effect can be obtained. Furthermore, since the sawtooth interval d of the opening/closing plate 3 is larger than the radius of the steel balls, it is convenient for the opening/closing plate 3 to be inserted smoothly into the ball array of the gutter 1.
