Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The crime-prevention type metal body detector of the present invention is installed inside the winning port of the game machine, emits an encouragement ball due to the metal body passing through the detection path of the detector, or at a metal processing factory, The present invention relates to the counting of processed products due to the processed metal body passing through the detection hole, or the application to a metal body detector in an industrial automatic equipment product.

[0002]

[Prior art]

 At present, electromagnetic induction type, contact type, and photoelectric type are practically used for these metal body detectors.

In the electromagnetic induction type, a coil is used in the detection part of the detector, a high frequency oscillation circuit is configured by combining with a capacitor, a semiconductor, etc., and when the metal body approaches the coil, the oscillation state of the oscillation circuit changes. The contact method is a method in which a lever is attached to a contact switch and the contact is opened and closed by interlocking with the contact part and the metal body comes into contact with the lever. Has an infrared light emitting element at one end of the wall of the detection path of the detector, and a light receiving element at the wall of the detection path facing each other across the detection path so that the metal body passes through the detection path. At this time, the method is to detect the passage or non-passage of the metal body by blocking the light path between the light emitting element and the light receiving element.

[0004]

[Problems to be solved by the device]

 However, the electromagnetic induction method is prone to malfunction due to reception of electromagnetic waves emitted from electromagnetic wave emitting devices such as general commercial radio, radio, television broadcasting, and amateur radio, and the contact method uses dust on the contact points of the switch. Is likely to adhere to the contacts, or the contacts may wear and cause chattering or inoperability.In addition, the photoelectric method emits light when the light-emitting element deteriorates with time and becomes inoperable. , Dust adheres to the optical path between the light receiving elements, making it inoperable.

The crime prevention type metal body detector of the present invention can solve these drawbacks and provide an excellent crime prevention type metal body detector which has a long life and is inexpensive.

[0006]

[Means for Solving the Problems]

 As a means for solving these problems, in the case of claim 1 of the present invention, a detection path through which a metal body, which is the object to be detected, can pass is provided at one end of the case body, and a lead is provided on the wall surface of the detection path. Place the switch and connect both ends of the reed switch to the input side of the electronic circuit. The magnetic material that controls the reed switch is placed on the left and right of the wall of the detection path when viewed from the reed switch side.

[0007]

[Action]

 By arranging the magnetic material on the left and right sides of the detection path when viewed from the side of the reed switch, when the metal does not pass through the detection path, the reed switch senses the magnetic force of the left and right magnetic materials and the opening / closing part Since it is "closed", the electronic circuit becomes conductive, the output level becomes "H" level, and current flows through the external load circuit.

When the metal body passes through the detection path, the magnetic field lines of the left magnetic body enter the right magnetic body through the metal body (or vice versa) to form a closed magnetic circuit, and the reed switch has no magnetic field lines. Since it reaches, the open / close part of the reed switch becomes “open”, the electronic circuit also becomes non-conductive, and the output level becomes “L” level, so that no current flows in the load circuit.

[0009]

【Example】

 Each drawing is an example in which the present invention is applied to a game machine, FIG. 1 is an exploded view of the crime prevention type metal body detector according to claim 1, FIG. 2 is an electronic circuit diagram thereof, and FIG. 2 is an exploded view of the crime prevention type metal body detector, and FIG. 4 is its electronic circuit diagram.

Therefore, the embodiment will be described in detail with reference to FIGS. 1 and 2 according to claim 1 of the present invention.

In FIG. 1, the case body 11 is made of synthetic resin and is molded into a rectangular housing body. A metal body 22 is formed in a part of the case body 11 in the thickness direction of the case body 11. A detection path 12 for passing is provided, a reed switch 13 is arranged at one end of the wall surface of the detection path 12, and both ends of the reed switch 13 are connected to the input side of the electronic circuit 16.

As shown in FIG. 1, the magnetic body 14 is disposed on the left and right wall surfaces of the detection path 12, and when the crime prevention type metal detector is applied to the metal body detector of the game machine, magnetic leakage is prevented. Therefore, the iron piece 15 is attached between the ends of the left and right magnetic bodies 14.

The power source terminal / electronic circuit output terminal 20 and the like are integrally assembled on the circuit board 17 and housed in a wide portion of the case body 11.

With reference to FIG. 2, the positive power supply terminal 19 is a positive power supply from the gaming machine body, and the negative power supply terminal / electronic circuit output terminal 20 is connected to the gaming machine, and the load circuit 21 (game Negative power is supplied from the amusement machine via the internal circuit of the machine).

The relationship between the reed switch 13 and the magnetic body 14 is that when the metal body 22 does not exist in the detection path 12, the opening / closing part of the reed switch 13 is “closed” due to the magnetic force of the left and right magnetic bodies 14. A magnetic body 14 having such a magnetic force and a lead switch 13 having an appropriate impression value are selected.

The operation of the embodiment of the present invention will be described below.

Now, when the metal body 22 does not pass through the detection path 12, the reed switch 13 senses the magnetic force of both magnetic bodies 14 to maintain the open / close portion in the “closed” state, and the reed switch 13 The output voltage of the electronic circuit 16 connected to is also maintained at the "H" level.

More specifically, when the metal body 22 does not pass through the detection path 12, the opening / closing portion of the lead switch 13 is “closed”, and the electronic circuit 16 is in a conductive state. At this time, when the collector current of the transistor 17 is set to flow 8 mA, if the internal resistance of the external load circuit 21 (internal circuit of the gaming machine) is set to 2 kΩ, the voltage generated across the load circuit 21 ( The output voltage) is 16 V according to Ohm's law.

Next, when the metal body 22 passes through the detection path 12, between the magnetic body 14 and the metal body 22 on the left and right of the detection path 12, the right side of the magnetic body 14, the metal body 22, the magnetic body 22, 14 a closed magnetic circuit on the left (or vice versa) is constructed, a magnetic field line does not reach the reed switch 13, and a reverse magnetic circuit does not reach the reed switch 13, and a magnetic field line does not reach the reed switch 13. The open / close part of the reed switch 13 is in the "open" state.

As a result, the electronic circuit 16 becomes non-conductive (current does not flow through the transistor 17) and the voltage (output voltage) generated across the load circuit 21 becomes zero.

[0021]

[Effect of the invention]

 Here, when the crime-prevention type metal body detector of the present invention is applied to a game machine, it is "crime-proof type". When claim 1 is explained, the metal body does not pass through the detection path as detailed in the embodiment. At this time, the open / close part of the reed switch is always "closed". Also, in the case of claim 2, the output of the Hall IC is always at "L" level.

In this state, when magnetism is intentionally given from the outside of the gaming machine by using a magnetic body for the purpose of causing malfunction of the gaming machine, between the ends of both magnetic bodies of the metal detector of the present invention Since the is equipped with a magnetic leakage prevention iron piece, the reed switch is completely unaffected by external magnetism. Also, considering the worst condition, even if magnetism is received, the open / close part of the reed switch is already "closed", so it does not become "closed". Further, according to claim 2, when the metal body does not pass through the detection path, the Hall IC is already "L" to the external magnetism as in the case of the reed switch. Does not mean

When a metal body is passing through the detection path, even if the opening / closing part of the reed switch is changed from “open” to “closed” in consideration of the worst case due to external magnetism, the inside of the detection path The metal body of becomes impermeable, and the action has a negative effect. Also, in the case of claim 2, the Hall IC changes from the “L” level to the “H” level, and the action has a negative effect as in the case of the reed switch.

The reed switch used in the crime-prevention type metal body detector of the present invention is a glass tube filled with an inert gas and a contact capable of detecting a magnetic body is enclosed in the connected electronic circuit. Therefore, only a very small current (20 μA in actual measurement value) flows through the contact part, which makes the contact life "permanent" (the manufacturer guarantees 100 million contact opening and closing times), and the electronic circuits installed Since it is permanent, the life as a metal body detector is extremely long.

When the Hall IC is used, the Hall IC is also a non-contact switch and the electronic circuit is also a non-contact switch, so the life as a metal body detector is extremely long, and it is similar to an exposure-type contact switch. It does not cause malfunction or chattering due to contact point wear or dust adhesion.It also causes malfunction due to dust adhesion or disturbance light in the optical path like the photoelectric type, and external electromagnetic waves like the electromagnetic induction type. It does not detect and cause malfunction.

The electronic circuit of the crime prevention type metal body detector of the present invention has a significantly reduced number of parts and is easy to assemble as compared with the electromagnetic induction type or photoelectric type electronic circuits, and is low in price and high in quality. A criminal metal body detector can be provided.
