BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a launch rail tool for a pachinko gaming machine, and more specifically, a pachinko ball (also referred to as a game ball) hit by a hitting ball launching device at a launching position is moved to the front of the game area. It relates to a launch rail tool that guides flight in the process.

[0002]

2. Description of the Related Art In a gaming machine of this type represented by a pachinko machine and an arrange ball machine, a ball feeding device and a ball launching device cooperate with each other to feed and launch a ball, and thereby a launch position (a base end portion of a launch rail) The game balls that have been sent one by one to and are seated and stationary are hit by a hitting member and also fly on the launch rails and are driven into the game area. In such a batted ball firing state, as one of the important items for proceeding a comfortable game, the proper flight performance of the game ball (hit ball), that is, the ball flying condition, is required. The suitability of flight performance is
It is considered to be an important technical factor enough to confirm the goodness of the hitting ball launching performance of the gaming machine. For that reason, regardless of the game machine, the launch rail tool for guiding the flight of the hit ball has been studied and ingenious from many directions for many years, and better flight performance and stable ball flight conditions have been pursued. ing.

[0003]

By the way, as for the launch rail tool implemented in the recent game machines, as one of the modes that can improve the flight performance (ball flying condition) of the hit ball described above, The “M type rail” commonly used as outlined in 11
What is also called is being favorably viewed and being used frequently. The launch rail tool 30 is formed into a V-shaped groove over the entire length by being molded into an M-shaped cross section on the front surface of a set base 31 mainly made of synthetic resin, which is positioned and set on the front side of the game auxiliary board F in the machine. A metal-formed (mainly stainless steel) rail 33 having a flight guide path 32 is attached by a screw or the like at a required firing inclination angle, and the set base 31
And a firing position P is formed between the rail 33 and the base end of the rail 33,
The whole is constructed as one rail tool 30 and can be handled.

Such a launch rail tool 30 is positioned and set on the game auxiliary board F of the game machine, and all the game machines in the game hall generally "tilt or slope" in the industry. because it is placed at a required after tilt angle, also referred to as, 12 as illustrated (a), the installation line Y ₁ -Y ₁ of the rear tilt angle α to the vertical Y-Y
It will be in a backward tilted state along the line, and in this state, the center of the flight guide path 32 of the rail 33 and the game ball.
(Hit ball) It is designed to be able to receive and guide under the seating condition of two-point contact under the condition that the ball center of B is aligned. The flight guide path 32 has a width (approximately 13 to 14 mm) appropriately larger than the diameter (about 11 mm) of the game ball (hit ball) B, and the path center is aligned with this width center position.

However, this firing rail tool 3 is considered to be preferable.
Even at 0, no measures have been taken to prevent lateral deviation / deflection with respect to the game ball (hit ball) B on the flight guide path 32. Therefore, the ball striking member of the ball striking device is displaced on the rotation locus along the road center and hits the game ball B, and the end of the ball hits the game ball B at the launch position P.
Even when a slight deviation part regarded as an allowable error is hit from the center of the ball, the hitting game ball B floats from the flight guide path 32 to cause a one-sided swing state, and FIG. a), (b)
As illustrated in FIG. 2, there may be a case where the two sides B and 32 are displaced inward by an interval difference x and fly in a one-sided swing state in contact with the inner side surface of the guide path 32 and the front surface of the set base 31, In addition, such flight defects could not be avoided.

In the flying defect of the hitting ball B described above, the hitting ball B in flight is caused by the difference in contact resistance value of the balls to the set base 31 and the rail 33 made of different materials.
May rotate in an unexpected direction, and as a result, it becomes difficult to accurately hit the ball B at a target portion within the game area, and the hitting position causes considerable variation, which results in stable flight of the hit ball and There was a big problem that it was impossible to continue a comfortable pachinko game by driving.
