Problems solved by technology

[0006] However, in this detection mechanism, the through hole 255 is composed of a combination of multiple components such as the housing 251, the shielding member 256, and the coil bobbin 252. If there is a deviation between the joint surfaces, there will be a deviation between the position where the ball P starts to be detected and the position where the ball P ends when the through-type metal ball detection device is detected.
Therefore, when the ball exists in the through hole, since the reference position of the output detection signal cannot be determined, it is difficult to use it for detecting the presence or absence of the ball in the structural design of the through-type metal ball detection device.
[0007] In addition, since the through hole is composed of multiple parts, a step difference is likely to occur on the inner peripheral surface of the through hole, which hinders the smooth passage of the ball when the step difference occurs.
Furthermore, each time the ball passes through the through hole, the passing speed is reduced, which becomes an obstacle when the ball passes, and has the problem of impairing the processing speed of the game machine itself.

Abstract

To build a reliable detection structure that can accurately detect a ball passing through a through hole and make the ball flow smoothly by eliminating the steps from the interior circumference of the through hole because the distance from the through hole end to the coil becomes accurate. The passing-through type metal ball detector has a coil spool wound around the exterior circumference of the through hole that makes a metal ball pass through, a wiring board with a sensor circuit connecting both ends of the coil wound around the coil spool, and a base equipped to be with the coil spool and the wiring board. The end face of the through hole formed in the coil spool is exposed in the axial direction from the end face of the outer shell member provided on the same end face side of the coil spool as a cover member of the coil spool.

Description

technical field [0001] The present invention relates to, for example, a through-type metal ball detection device built in a pachinko machine or the like to detect the presence or absence or the number of metal balls that have passed through a game, and more specifically, to a penetration-type metal ball detecting device that improves the accuracy of the detection position of a ball passing through a through hole Type metal ball detection device. Background technique [0002] Generally, in a game machine such as a pinball machine, when a metal ball (hereinafter referred to as a ball) for a game is obtained from a winning opening provided on a game board, or when the ball passes through a payout passage, the penetration type metal ball detection device detects the metal ball. passing of the ball. [0003] As shown in Patent Document 1, a conventional through-type metal ball detection device has a configuration including a coil spool for winding a coil around an outer peripher...
