Benefits of technology
The present invention is a gaming machine with a gaming ball detection device. The device includes magnetic flux generation means and magnetic flux detection means. The magnetic flux generation means generates magnetic flux, while the magnetic flux detection means detects any changes in magnetic flux caused by the passage of the gaming ball through a predetermined region on the gaming board. The device is housed in a cut-out shape, which reduces production costs and allows for placement at any position on the gaming board. The magnetic flux generation means and magnetic flux detection means are provided in the same plane, which ensures accurate detection of the gaming ball. The housing case includes a metal plate that increases the efficiency of magnetic force transmission and improves the detection of the gaming ball. The invention reduces production costs and improves the accuracy of gaming ball detection.
Problems solved by technology
Therefore, a case body in such a conventional passing ball sensor needs portions, at which the magnetic field generation means and the Hall element are provided, across the through-hole, and therefore the case body becomes inevitably large.
And positions, at which the magnetic field generation means and the Hall element are provided, are limited and production costs of such a case are expensive.

The present invention provides a gaming machine comprising a gaming ball detection device for detecting a gaming ball having passed through a predetermined region of a gaming member provided on a gaming board, the gaming ball detection device comprising: magnetic flux generation means for generating a magnetic flux; and magnetic flux detection means for detecting a change in magnetic flux generated by the magnetic flux generation means, wherein the gaming member has a housing case in which the magnetic flux generation means and the magnetic flux detection means are housed side-by-side, facing the predetermined region, and the housing case is formed to have a cut-out shape in which a body of the housing case does not reach an extension of a line connecting a central point of the magnetic flux generation means with a central point of the gaming ball passing through the predetermined region, and the body of the housing case does not reach an extension of a line connecting a central point of the magnetic flux detection means with the central point of the gaming ball passing through the predetermined region.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims benefit of priority based on Japanese Patent Application No. 2005-189742 filed on Jun. 29, 2005. [0002] The contents of that application are incorporated by reference herein in their entirety. BACKGROUND OF THE INVENTION [0003] 1. Field of the Invention [0004] The present invention relates to a gaming machine comprising a gaming ball detection device for detecting a gaming ball having passed through a predetermined region of a gaming member. [0005] 2. Discussion of the Background [0006] As such a kind of conventional gaming machines, mentioned is a pachinko gaming machine. The gaming board face of this pachinko gaming machine is provided with a starting winning opening, a regular winning opening and a special winning opening, which a gaming ball can enter. These winning openings are provided with a passing ball sensor for detecting passage of the gaming ball. When the gaming ball enters these winning openings and...
