Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a sagging prevention structure for a guide gutter for guiding a prize ball in a prize ball tank to a prize ball discharging mechanism in a pachinko machine.

[Prior Art] Conventionally, in a pachinko machine, as is well known, a guide gutter having two ball passages is installed below a prize ball tank to guide the prize ball in the prize ball tank to a prize ball discharging mechanism. Every time a prize ball is generated, a certain number of prize balls are discharged to the prize ball discharge gutter. In recent years, pachinko machines, which are equipped with two prize ball releasing mechanisms that release different prize balls to increase the enjoyment of the game, and that allow different prize balls to be released depending on the type of prize ball, are becoming popular. . In such a pachinko machine, a guide gutter having three ball passages is usually used.

[Problems to be Solved by the Invention] In the meantime, each of the above-described guide gutters is formed of a synthetic resin into a substantially L-shaped side surface with one side as an opening surface. It is to be attached in close contact with. For this reason, there is a problem that the side wall portion located on the opposite side of the opening surface is inevitably bent inward and obstructs the flow of the prize ball.

It is an object of the present invention to provide a guide gutter deflection prevention structure for a pachinko machine that can be applied to any of the above two types of pachinko machine guide gutters.

[Means for Solving the Problems] In order to achieve the above object, the present invention is a first prize which is rotatably mounted on the back surface of a game board, and on which the prize ball tank and the number of prize balls discharged are different. A ball releasing mechanism and a second prize ball discharging mechanism are attached, and the prize ball in the prize ball tank
In a pachinko machine equipped with a mechanism board equipped with a guide gutter having three ball passages leading to the ball discharge mechanism of the guide ball, the back surface of the mechanism board has a distance approximately equal to the width of the two ball passages of the guide gutter. A holding protrusion is provided and a fitting recess is provided at the rear end of the holding protrusion. On the other hand, the spacer member is formed by providing a protrusion that fits in the fitting recess of the spacing protrusion at the front end of the hollow cylindrical body having a length substantially guttered to the width of the single ball passage of the guide trough. Then, the projection of the spacer member is fitted into the fitting recess of the spacing holding projection, and the spacer member is detachably attached to the spacing holding projection with a screw, whereby the rear end of the hollow cylindrical body of the spacer member is attached to the side wall of the guide trough. It is designed to be in contact with the inner surface.

[Operation] As a result, in the guide gutter having the three ball passages, the rear end of the spacer member comes into contact with the inner surface of the side wall to reliably prevent the side wall from bending inward. Further, in the case of a pachinko machine that uses a guide gutter having two ball passages, the screws are removed and the spacer member is removed from the gap holding projection. As a result, the rear end of the spacing holding projection comes into contact with the inner surface of the side wall of the guide gutter, and the inner wall of the side wall is reliably prevented from bending.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. The first is a back view of a pachinko machine to which the present invention is applied, 1 is a game board mounting frame, 2 is a game board, and 3 is a mechanism plate rotatably mounted on the back surface of the game board 2. The mechanism plate 3 is

Is formed. The prize ball tank 6 is mounted on the upper back surface of the plate-shaped portion 3a. Below the prize ball tank 6, there are three ball passages 7a ...
A guide gutter 8 having 7c is installed. The guide gutter 8 is formed in a substantially L shape when viewed from the side by a side wall 8a and a bottom wall 8b which are opened on the side surface on the side that abuts the mechanism plate 3 and are located on the opposite side of the opening side surface. The first prize ball releasing mechanism 9 and the second prize ball releasing mechanism 10 are provided on one side of the back surface of the plate-like portion 3a.
The first prize ball discharging mechanism 9 is connected to the two ball passages 7a and 7b of the guide trough 8, and the second prize ball discharging mechanism 10 is one ball passage 7c of the guide trough 8. Are communicated. Below the first and second prize ball discharging mechanisms 9 and 10, a prize ball discharging gutter 11 for guiding the discharged prize balls to the hitting ball supply tray on the front surface of the pachinko machine is formed. Further, the mechanism plate 3 has a first winning ball discharging processing mechanism 12 and a second winning ball discharging processing mechanism 12 for discharging the winning balls collected in the first winning ball collecting section 4 one by one.
A second winning ball discharging processing mechanism 13 for discharging the winning balls collected in the winning ball collecting unit 5 one by one out of the machine. Then, by the operation of the first winning ball discharge processing mechanism 12,
A predetermined number, for example, 13 prize balls are discharged from the prize ball discharging mechanism 9 of the prize ball discharging gutter 11 to the second prize ball discharging processing mechanism 13.
By the operation of, the predetermined number of, for example, 7 prize balls are discharged from the second prize ball discharge mechanism 10 to the prize ball discharge gutter 11.

Therefore, in the present invention, as shown in FIGS. 2 and 4, it is the back surface of the plate-like portion 3a of the mechanism plate 3 and the side wall 8 of the guide gutter 8.
A space holding projection 14 is integrally formed at a position corresponding to a. The space-holding projection 14 is selected such that its protruding length is approximately equal to the width of the two ball passages 7a, 7b of the guide gutter 8. Further, a circular fitting recess 141 is formed in the center of the rear end of the spacing holding projection 14, and a screw hole 142 is formed in the center of the fitting recess 141.
Is provided. A spacer member 15 is attached to the spacing holding protrusion 14.

As shown in FIG. 3, the spacer member 15 has a hollow cylindrical body 151 which is made of synthetic resin or the like and has an open rear end. 1
A column-shaped projection 152 that fits into 41 is integrally formed to project,
A screw insertion hole 153 penetrating the inside of the hollow cylindrical body 151 is formed at the center of the protrusion 152. The length of the hollow cylinder 151 is selected to be substantially equal to the width of the single ball passage 7c of the guide gutter 8. In addition, the protrusion length of the protrusion 152 is equal to
The depth is selected so as to substantially match the depth of the fitting recess 141 of 4.
