In the case where the transmitting coil row group is arranged on the front side and the receiving coil row group is arranged below the transmitting coil row group, the transmitting coil row group acts as a shield and protects the receiving side which is easily affected.

The sending and receiving units are rectangular.

If the patterns are arranged orthogonally, the detection unit will operate accurately.

"Example" Hereinafter, various embodiments of the present invention will be described based on the drawings.

1 to 5 show a first embodiment of the present invention.

As shown in FIGS. 1 and 2, a pachinko game machine 1
A detection matrix 20 is attached along the board surface 11 of 0.

The board surface 11 of the pachinko game machine 10 forms a game area on the inside of the guide rail 12, and a large number of nails 13, 13, . ... has been opened, and an out hole 15 has been opened at the lower end of the game area. Further, detection points a and b for counting balls are set.

The glass lid covering the board surface 11 has a double structure consisting of a front glass body 16 and an inner glass body 17.

The front face of the pachinko game machine 10 is provided with a launch handle 18 for operating the launch operation of the pachinko balls B, and a ball surface 19 for receiving and receiving the balls.

The detection matrix 20 is provided on the inner glass body 17, which is the inner side of the two glass bodies that cover the board surface 11 and is on the board surface side.

The inner glass body 17 is an inner protective glass 17a.

It has a triple structure of a glass base substrate 17b and an outer glass 17c, and a transmitting coil row group 21 is sandwiched between the inner protective glass 17a and the glass base substrate 17b, and the glass base substrate 17b and the outer glass 17c are A receiving coil array group 25 is sandwiched between them.

A transparent conductor 11128 for shielding is attached to the surface of the outer glass 17c, which is the front side of the receiving coil array group 25.

As shown in FIGS. 2 to 4, the transmitting coil row group 21 is
Rectangular and open ring-shaped transmitting units 22a, 22a, . . . are formed by bending two conductors into sets, and are arranged in a regular array by arranging continuous transmitting coil rows 22, 22, . . . in one direction.

The receiving coil row group 25 is formed by bending two conductors into a set, and transmitting units 22a, 2 of the transmitting coil rows 22, 22...
Rectangular open ring-shaped reception units 26a, 26a are inductively coupled to 2a-... and whose pattern is orthogonal to the transmission unit 22a.
. . . is formed by arranging continuous receiving coil rows 26, 26 . . .

Receiving coil rows 26.26... are transmitting coil rows 22.2
2... are arranged in the cross direction, and the transmission unit is 2.
2a, 22a... and a receiving unit 26a.

Each superimposed part such as 26a... is a detection unit 20a, 20 that detects the pachinko ball B by impedance change.
It is doing a...

External connection terminals 23° 27 are provided at the ends of each transmitting coil row group 21 and receiving coil column group 25, respectively, and as shown in FIG. 4, the detection units 20a, 20a, .
・Some of the holes correspond to the safe holes 14a, 14a-.

Note that the pattern shapes of the transmission unit 22a and the reception unit 26a are delicate depending on the size of the pachinko ball B. If it is too large, the resolution will be poor, and if it is too small, multiple detections will be made for one pachinko ball B. The units react, making it difficult to grasp the positional relationship. The thickness of the conductor also has a large effect; if it is thin, the impedance will be too high, and if it is thick, the inner diameter of the pattern will become small, resulting in poor sensitivity.

In addition, the transmission unit 22a of the detection unit 2'Oa and the reception unit 2
Is the distance from 6a closely related to the thickness of the conductor?
It shows a good result of about 2.5 to 3.5-■.

Although the patterns of the transmitting unit 22a and the receiving unit 26a do not necessarily have to be square, for example, the dimensions (unit -) shown in FIG. 5 were practical. The conductor forming the pattern is a transparent conductive film such as an indium oxide film or a tin oxide film.

Next, the effect will be explained.

When a constant signal such as a sine wave is transmitted to each of the transmitting coil row groups 21 of the detection matrix 20, the receiving units 26a, 26a- of the receiving coil row 26 and the transmitting units 22a, 22a- of the transmitting coil row 22 are inductively coupled. Transmitting coil row group 2
1, a predetermined impedance value is generated.

Transmission units 22a, 22a- and reception units 26a.

26a... When the pachinko ball B passes through the detection unit 20a superimposed with each other, the impedance value of the transmitting coil row group 21 changes, and the receiving current of the corresponding receiving coil row 26 also changes.

By detecting the transmitting coil row 22 where the impedance value has changed and the receiving coil row 26 where the receiving current has changed, the position of the pachinko ball B can be grasped as the coordinates of the position where the matrices intersect.

The detection matrix 20 is connected to a management device not shown,
This management device is a safe hole 14a.

Detection unit 20a corresponding to 14a...

20a... are stored, and the position of the out hole 15 is also stored. The management device monitors the state of the pachinko balls B as the game progresses.

Depending on the situation, the data may be used to manage the setting, check for abnormalities due to fraud, or use as data for nail adjustments, etc.

The transparent conductive film 28 shields and protects the detection matrix 20 from any electrical influence even if a human body, a foreign object, or other metal or dielectric comes close to the one-surface glass body 16.

FIG. 6 shows a second embodiment. Since the basic configuration is the same, the explanation will be made using the same reference numerals.

In this embodiment, the transparent conductive film for shielding, which was provided on the surface of the outer glass 17c of the inner glass body 17 in the first embodiment, is attached to the inner surface of the front glass body 16.

In this embodiment, the transparent conductive film 28 for shielding is provided at a position that is spaced apart from the detection matrix 20, so that it is more effectively protected against interference from the human body or foreign objects from the surface of the surface glass body 16. I can do it.

Next, a third embodiment will be described.

The third embodiment relates to the structure of a combination of a detection matrix and glass, and since the drawings are similar to the inner glass body 17 of FIGS. 1 and 6, the description will be made with reference to those drawings.

That is, in this embodiment, unlike the first embodiment and the second embodiment, the transmitting coil row group 21 is sandwiched between the internal protective glass 17a and the glass base substrate 17b, and the glass base substrate 1
This specifies a structure in which the receiving coil array group 25 is sandwiched between the receiving coil array group 7b and the outer glass 17c.

In the third embodiment, a transmitting coil row group 21 and a receiving coil column group 25 are attached by printing so as to face each other on both sides of a glass base substrate 17b and bonded together to form a unit. A detection matrix 20 is constituted by sandwiching the detection matrix 20 between the two.

The third embodiment has the advantage that the sensing matrix 20 can be easily molded.

Although each of the above embodiments describes a pachinko game machine, the use of the detection matrix is not limited to pachinko game machines.
It can be applied to detection devices that count and inspect pachinko balls at prize exchange locations. If the characteristics of the detection unit are made more sensitive, it is also possible to detect false balls.

Furthermore, if the density of the detection matrix is set appropriately, it is possible to follow the trajectory of pachinko balls, and the game can be monitored in detail. The detection matrix may be arranged on the back side of the board of the pachinko game machine.

"Effects of the Invention" According to the pachinko game machine according to the present invention, it is possible to obtain data such as the trajectory of pachinko balls on the 51 sides, the number of pachinko balls hit by a player, and the rate of balls entering the safe hole. Since the details of the game can be known remotely, the level of accounting management for pachinko game machines can be improved.

Furthermore, the pachinko ball detection device can accurately detect pachinko balls and can also extract fake balls.
