Description

  The present invention relates to a ball game machine equipped with magnetic detection means for detecting fraudulent acts caused by magnets or the like.

  In general, a pachinko machine, which is one of the ball game machines, is a game that is secured by sucking a game ball launched on the game board with a powerful magnet through a glass plate or the like disposed on the front of the game machine. Magnetic detection means for detecting an illegal act called so-called magnet goto, which illegally acquires a winning ball by guiding the ball to a winning opening, is provided.

  For example, Japanese Patent Application Laid-Open No. 2005-137877 discloses an invention of an illegal magnetic detection sensor (magnetic detection means) for a gaming machine configured using a magnetic detection reed switch (see FIG. 4) as a magnetic sensor. Yes. The magnetic detection reed switch described in this publication is widely used in practice because it is inexpensive and can be configured extremely small.

  The reed switch (magnetic sensor) for magnetic detection described in Patent Document 1 described above is a magnetic switch in which two magnetic detection pieces made of a magnetic material facing each other through a minute gap are approached to a gaming machine for illegal purposes. The magnetic detection pieces are brought into contact with each other by the attractive force of the magnetic pole magnetically induced by the magnetic field to generate a signal, and the direction of the detectable magnetic field has directivity. That is, as shown in FIG. 6 (a), the thickness direction of the magnetic detection pieces 100a and 100b as indicated by an arrow A in the figure with respect to the two magnetic detection pieces 100a and 100b facing each other through a minute gap. When the magnetic field in the direction in which the magnetic field lines are linked (acting) approaches, the S pole is magnetically induced on the surface of the magnet M side of the magnet M side of the magnet M detection piece 100b, and on the side of the magnet detection side 100a on the opposite side. The N pole is magnetically induced on the surface. Similarly, the S pole is magnetically induced on the surface of the other magnetic detection piece 100a facing the magnetic detection piece 100b, and the N pole is magnetically induced on the opposite surface. Accordingly, the S pole magnetically induced on the surface of the magnetic detection piece 100a facing the magnetic detection piece 100b and the N pole of the magnetic detection piece 100b facing the magnetic detection piece 100a are attracted and contacted. The switch is turned on to generate a signal.

  However, as shown in FIG. 6 (b), when the direction of the magnetic field of the magnet M approaching for improper purpose is linked to the longitudinal direction of the magnetic detection pieces 100a and 100b as indicated by an arrow B in the figure, Although not shown, when the magnetic detection pieces 100a and 100b are linked in the width direction, magnetic induction as described with reference to FIG. 6A does not occur and the switch is not turned on.

In other words, this conventional magnetic detection reed switch has directivity in the magnetic field (line of magnetic force) acting in the thickness direction of the two magnetic detection pieces 100a and 100b as shown in FIG. There was a problem that it was difficult to detect a magnetic field.
In addition, a magnetic detector that has almost no directivity in the detection direction of a magnetic field and can detect a magnetic field in almost all directions has a complicated structure, is large, and is expensive.
