着したものである。FIG. 1 is a perspective view of a pachinko ball detection device according to the present invention, in which the detection device is installed outside a ball passing section 1 formed in a cylindrical shape. This pachinko ball detection device 10 has a plate member 11 made of a ferromagnetic material such as iron formed in an oval shape, and magnets 12 are fixed to the corners of the plate member 11.
In the lower part, that is, in the L direction of the substantially horizontally extending portion 11a,
The substrate 13 made of non-magnetic material is supported by a suitable support member 14.
When a vertical magnetic field is applied to the Hall ICl3, which has a Hall element and an amplifier circuit integrated on the same chip, an electromotive force is generated due to the Hall effect. It is positioned and fixed so that the

わち検出信号を発生するように構成されている。As shown in Fig. 2, the Hall ICl3 is equipped with a power supply circuit that applies a constant voltage V, and a direction perpendicular to the drawing (in Fig. 1).
A comparator circuit 16 that inputs the amplified electromotive force generated from the Hall ICl3 by applying a magnetic field to the
It is configured to not output unless the electromotive force of Cl3 is less than a predetermined reference value, and to generate a fixed output, that is, a detection signal, when the electromotive force is less than the reference value.
次に、第1図の実施例によるパチンコ球検出の原理を第
3図によって説明する。Next, the principle of pachinko ball detection according to the embodiment shown in FIG. 1 will be explained with reference to FIG. 3.
まず、磁石12による磁界は、強磁性体から成る部材1

る起電力は僅かであり、コンパレータ回路16は出力し
ない。First, the magnetic field generated by the magnet 12 is applied to a member 1 made of a ferromagnetic material.
When the pachinko ball 2 is formed inside the L-shape while being shielded from the external magnetic field by the magnet 12 and the pachinko ball 2 does not exist in the pachinko ball passage part l, the magnetic force lines coming out from the magnet N8i of the magnet 12 are as shown in Fig. 3 (A ), cross the hole ICl3 from the lower right to the left. In other words, the L-shaped RR material 11
The position of the hole ICl3 relative to the pachinko ball is determined so that it intersects with the line of magnetic force going from the lower right to the left to the left when there is no pachinko ball. Therefore, in this case, the electromotive force generated by the Hall ICl3 is small, and the comparator circuit 16 does not output.

It becomes almost vertical towards Hi. Therefore, the Hall ICl3 generates an electromotive force greater than the above-mentioned reference value, and the comparator circuit 16 outputs the electromotive force. Therefore, pachinko ball 2
can be detected every time it passes.

In order to pay out a predetermined number (for example, 13) of pachinko balls each time, as shown in FIG. By attaching the pachinko ball detection device 10 to the ball sending position, a count is made every time a pachinko ball 2 sent out by the rotation of the drum 24 is detected.

ことができるという効果が得られる。As described above, in the sphere detection device of the present invention, a magnet is arranged near the corner of a ferromagnetic material formed in an abbreviated shape, and a sphere made of a magnetic material is positioned within the magnetic field of this magnet. Since the Hall element is placed in a position that generates an electromotive force due to the change in magnetic flux density that occurs when In addition to the advantages of the one-town contact method, which has excellent durability and is unaffected by dust and dirt, the L-shaped ferromagnetic +1 body acts as a magnetic shield, blocking the effects of static electricity and external magnetic fields. Furthermore, by combining the magnet and Hall element with the L-shaped ferromagnetic material, the entire structure can be made compact and can be made into a unit, making it ideal even in places where space is limited. The effect is that the detection position can be easily set.
